13 Best Apps to Make Money Taking Surveys Online

hey guys justin bryant here from self-made success.com in this video I’m going to show you the 13 best apps to make money from taking surveys online so if you want to make some extra money you want to basically just do some of this in your free time do a few surveys answer a few questions give your opinion out and get paid to do it then these are 13 of the best and most highly rated apps that you can do this with so the first one is called inbox dollars and inbox dollars is nice because not only do they let you make money from surveys not only are they a very highly rated app with four stars out of 62,000 plus ratings that’s just on Android alone but they also give you a lot of other ways to make money so you can also make money checking email searching the internet watching videos referring friends to use it and things like that so obviously this video is more geared towards surveys but you know you can kind of see what this looks like they have all kinds of different offers where you earn money from them it tells you kind of what you have as far as how much money is worth instead of how many points and having to do all these exchanges of points and stuff like that so it cuts out that kind of hassle from having to deal with all those points and redeeming them for rewards they actually tell you how much money you actually make from what you’re doing so inbox dollars definitely one of the top ones I recommend as far as giving you lots of options while also offering surveys number two is swag bucks so swag bucks is another one they have a couple different apps I’m going to show you one is this one right here which is the swag bucks serve a specific app it’s not as highly rated they don’t give you as many choices of what you can do to make money on this one this is just surveys only you can kind of see what it looks like but you redeem everything for gift cards and other rewards but you know they also offer PayPal which I always think is a nice bonus it’s a lot better to do something like PayPal in my opinion than it is to just do like a gift card but this is specific to surveys if you want the main app for swag bucks it’s called swag bucks best app that pays and it gives you a lot more options for how you make money so you can watch videos you can surf the internet as well as take surveys and things like that so swag bucks the main app or swag bucks answer either way made by the same company and you can make money from surveys number three surveys on the go so surveys on the go the reason I like this one and as you can see a lot of others do as well this is one of the highest-rated on my list of top survey apps you can see it’s a four-point four out of five on Google Play but surveys on the go is a free app that allows you to make money specifically from surveys so they pretty much specialize in surveys they don’t really give you a lot of other options but they do what they do very well so it’s very simple it tells you what category they’re in what the survey is kind of about and it tells you how much each survey is going to pay you in terms of dollars instead of just being like oh well you have to earn a thousand credits and then exchange the credits where five thousand credits equals five dollars to this gift card so they don’t overcomplicate it they just tell you exactly how much money in the currency you use will be paid to you from each survey so it’s much easier to just get an idea of which ones you should do and you know you can make some pretty decent extra money if you do all these surveys another one is Google opinion rewards and you know Google is going to deliver a pretty product considering they’re one of the biggest companies in the world and they have a reputation they have to hold up as a quality company they have a four star rating out of five hundred thousand plus reviews definitely the most reviewed and the most used of any of these survey apps I’m going to mention but this is just on Google Play they have a lot of users of course but for Google the difference between this and a lot of the others is of course it’s made by a top company but it’s also going to pay you in Google Play credits so you see here you earn in Google Play credit instead of actual just cash so or you don’t really get a choice of how you get your money in in other words instead of getting it through PayPal or having the choice to do an Amazon or Starbucks gift card you don’t really have any of that it’s just all google play credits but pretty much all of your entertainment needs can be met by Google Play because they offer video games music books movies TV shows and Android apps all in Google Play alone so these credits can go a long way towards that type of stuff number five is ipoll ipoll has been around a good while and they are one of the top survey specific apps for paying you they have just under four star rating out of just under eighteen thousand users on Google Play alone and they ask you to kind of create a profile and then you can start taking surveys so they have all types of different surveys you can search for something specifically which is nice if you want to do surveys on specific types of categories you can get notifications you can see push notifications as an option right there and you just have all kinds of different surveys but it will actually remind you to take some if you trying to make some extra money from me so nice but you can redeem your rewards on a ipoll website so just keep that in mind you have to go to actual ipoll comm website to redeem your rewards number six is YouGov so you gov is probably a little lesser-known than the ones I’ve mentioned so far but they have daily surveys that you can do and it’s still a really nice app one thing I love about you go that kind of makes them a little different is you can see how other people answered the questions and that can actually maybe give you some more incentive to keep doing it because you’re interested in seeing what other people think besides just yourself so instead of just doing like a big multiple choice question air and just answering one and then go into the next one you actually get to see what other people say as well so that’s nice good rating not as many users as the others but it’s still effective number seven is called I say so you may have heard of I say mobile it’s actually called I say Rewards your opinion now but they have been around a while they are a top survey app and they specialize in surveys they don’t really have no not like inbox dollars or swag bucks where they give you all these different choices of stuff to do it’s pretty much just polls and surveys they will give you notifications on your lock screen for new surveys that you can take they have a lot of different rewards you can do and they tell you of course how much your points can get you as you take more surveys it tells you kind of the progress bar of how much farther you have to go in your survey which is nice if you’re kind of timing yourself maybe you’re waiting in line somewhere maybe you’re in a drive-through or something trying to get through a survey pretty quickly it’ll actually tell you your progress on that little bar there so a lot of them don’t do that which is nice that they do but and then it tells you how many points and the duration so it’s very you know user-friendly as far as giving you an idea of how long you’ll take to do these surveys but I say mobile spin around a good while and it’s it’s a reputable company and you can make some nice extra money from that number eight is quick thoughts quick thoughts is also very highly rated one of the higher rated ones it’s four stars actually a little over four stars i think yeah 4.1 stars and it’s got just under fifty one thousand people that have reviewed it on google play alone so it’s definitely one of the more popular ones and the thing that they do is they pay you an amazon gift card so you don’t really have a choice of how you get paid so if you’re looking for PayPal money or you’re looking for actual checks in the mail in cash or you want credits to something besides Amazon maybe you don’t use Amazon that much then this is not going to be a great app for you but if you use Amazon which pretty much has everything you could ever want to buy on there then you get paid an Amazon gift cards and you can get a lot of them through this site because they have a lot of sources which means they have a lot of surveys meaning you can get paid more they have over 1,000 sources as you can see you just share your opinions and it’s on your phone so it’s mobile and it’s easy to use you can find surveys you want to search for something specific they’ll even do location-based and stuff like that so they have all kinds of stuff that you can do a lot of different types of surveys because of their vast amount of sources and they help you save money on Amazon number 9 is cash reward so cash reward is an app that’s also highly rated one of the better ratings it’s over four stars I have 16,000 plus reviews on Google Play alone and what’s good what’s good about them is they do offer PayPal as you can see here they offer Amazon PayPal and a few other for converting your points to money but I think PayPal is usually the way to go so you can put it directly in your account or you can use is use it straight from PayPal and you just kind of create a quick account add your email and everything 4.3 stars definitely the highest rated on this list but you can also make money from other things kind of like inbox dollars and some of these others like swag bucks where you can actually make money from also downloading free apps downloading paid apps or trying them out registering for free sites watching ads playing free games you can get paid from a lot of different things so they’re just a solid app they really don’t have a lot of weaknesses number 10 is survey many so survey many kind of specializes more in surveys you can see this with Apple looks like it’s got a very good rating not quite as many users not quite as well known as some of these others I’ve been shinned but they do have a lot of different rewards they also have promotions that they’re doing all the time as you can see this is an example of a sonic drive-in thing that they have going on but you can earn rewards you get points you redeem those points when you click the button in the lower left corner one of these will probably show you that button yes see you down here you select redeem rewards that bottom left corner button and then you can exchange your points for money but they have stuff about like your experiences with restaurants what kind of music you listen to or they have all kinds of stuff that you can do they have all kinds of different rewards as you can see all these different gift cards you can get and things like that but in their highly rated so that’s always good when you know that you can kind of trust the app because a lot of people have tried it and given their thoughts on it number eleven easy shift and easy shift is not quite as highly rated but it still has about three stars which is decent it’s not as widely used as some of the other ones but it’s still one of the top survey apps if you just want to do as many surveys and make as much extra money as possible you know you can make probably an extra you know few hundred few thousand dollars a year depending on how many of these you actually do and how consistently you do them but easy shift is another one to do that if you’re just trying to do as many as possible you might want to throw in there they are more location-based in a way one nice thing about them that kind of separates them from some others depending on what you’re comparing it to is they do not have restrictions or an application process so you can see there in the features it doesn’t have any of that stuff in there which is really nice because it allows you to automatically be able to partake in any of the surveys that they have on they’re not worrying about what your occupation is your education level your demographic or any of that stuff so they’re not picky about who takes their surveys and that’s one really nice thing about them and it basically just tells you how much you make in terms of money instead of how much you make in terms of you know points and then having to exchange points so it kind of cuts out the hassle of that number twelve is zap surveys and zap surveys has a pretty good rating not a lot of users really but it’s still a solid app like I said is another one you would throw in if you just want to do as many surveys as possible make as much extra money as possible they have frequent surveys and you can also make small donations by doing these surveys to children in need and other causes so you know they give to charity you also make money it’s not like all the money you make goes to a charity and you don’t get to keep anything it does a little both so you’re kind of feeling good about yourself when you do these surveys and that’s why that’s one reason why I think their popularity is going to grow more and more but you get paid pretty well in your first survey as you can see I think it’s said on here yeah guaranteed at least six dollars on your first survey which is nice a little part of it they give some money to charity when you do these surveys you get to keep what you earn and then they do all kind of stuff like which one do you think looks best what do you think about this which is funny to you so they’re actually pretty fun surveys it’s not like okay well not going to ask you a lot of like boring stuff it’s actually like okay what picture what logo looks cooler you know how you feel about this how you text you know stuff that actually matters stuff that’s actually kind of entertaining to you to answer questions at the house so then it tells you your lifetime earnings how much you’ve helped children around the world with the cause and how much you’ve actually earned and kept so that’s really nice it’s a really solid app and it has a really good cause behind it and last but not least is earning station with number 13 and earning station is a fairly well rated app it doesn’t have near as many users as most of the others I’ve mentioned but you know do as many as you can if you want to make the most money off of surveys see it’s pretty easy to sign in just an email and a password or you can sign it with Facebook you have kind of a little profile on the side that tells you how many points you have gives you a quick link to redeem them for rewards it tells you how many surveys that you can do today and they also have other offers and things like that you can watch videos you can invite friends to do it and get bonuses for stuff like that but you know things like that and they have all kinds of different surveys that you can do probably around four per day or so and you can watch videos so it’s not like you have to do nothing but surveys they actually give you a few choices and so it can kind of give you a little more variety but you know they’re very detailed for sure in their display on the Google Play Store so you can kind of see all these different pictures about you know what it looks like but other than that that’s about it for this video I just want to do one that covers all the different surveys I know in a couple of my videos on line I have I’ve mentioned surveys as one way to make money online but I’ve never really done a video where I take all the top survey sites the high rated ones the ones that have quite a few users and put them in one place for you to kind of see which ones you should do so hopefully this video will be helpful to you if it was helpful please like and subscribe so and create more videos like this for you also if you want to let me know about your experiences with any of these or just let me know what you thought about the video in general let me know in the comments I’d love to hear from you they’d love to get your feedback and also get your advice whatever if you want to add to the topic and help others out that watch this video that would be great too and I’ll have the links to these pages and more show notes and related content to this

Is It A Scam!? Testing Online Survey Websites

hey guys welcome back to my channel today we’re doing another installment of random slash weird ways to make money on the internet today’s is the most requested it’s to test out if online surveys are actually legit so I’m gonna test a few of them and see if they actually work let’s do it alright so the first one that I’m gonna test is Opinion Outpost because i’ve heard of it before I mean this website just looks really gimmicky I kind of hate how it looks okay so then you just fill in basic info all right it says my first survey is ready so let’s see I’m interested in what are they gonna ask for me oh this is probably just to like figure out your demographic please confirm your employment status I’m self-employed which best describes your current self-employment these are really boring questions so far which best describes your department video production entertainer oh my god it’s an actor slash model such a youtuber that’s hilarious I have you deeper on here and what are you in the decision to purchase products or services in any of the fun areas accounting or tax or visit insurance pretty much everything alright so I just finished the first survey and it says congrats you’ve completed a profile so now I can take an actual one so let’s try it because yeah that one’s just asking all about you okay let’s see this oh this is kind of a similar thing it just is like asking about you using five words tell us what personal goals you would like to achieve in the next five years I hate that okay so now that I finished that one it says earn 25 points in just 34 minutes basic questions to start of course where do you live who are you what do you do oh it’s a survey about health care that’s kind of interesting do you or anyone and your household currently take any of the following medications when you think of hospitals in your area which ones come to mind first cedars-sinai I’ve never actually been to it right now who asked you some questions about the hospital you mentioned but I’ve never been to it okay whatever how familiar are you with it not really I guess I’ll put two because I’ve seen it okay so I just finished that survey it took like 30 minutes I think but now I have 25 points whatever that means so I’m gonna go to my account and try and figure out like what the points equal so it says that you can redeem a hundred points for $10 in paypal and it took me like 30 minutes to get 25 points so that is really not good that’s like what 250 an hour or something like that the good thing about this I don’t think you have to be a specific age to do it but I don’t know for sure but I got this email and it says five opinion points for a ten minute survey so five minutes I’ll just do it let’s see what this one’s about okay it says equity split and team relational norms what why did they think I was a good pick for this one you currently the owner or one of the owners of a venture startup such a business I always said I didn’t qualify it said thanks for my time did they get any points I don’t think I got a good point from that guys I’ll try another one it says take a survey so let’s see if there’s any available oh this isn’t even an actual one this was just one that would get me more surveys which of the following conditions – I have none I don’t watch TV s I don’t I don’t really have cable what so the following activity is do you plan to do in the next 12 months purchase a vacation home I wish ya none of these so since Opinion Outpost didn’t really have anything that I could actually take I’m gonna try another popular one that’s called swag bucks where you got to sign up all over again that’s kind of annoying okay now I have two swag bucks get free gift cards for answering service and brands so it’s pretty obvious like why they pay like they want the like market research it’s like a focus group online okay Wow now we have all these other ways add the swag button wow so this actually has a lot more stuff I like the interface of it oh you’re gonna earn swag bucks by just like buying stuff that you kind of buy anyway you can watch a slideshow like I’m guessing it’s like a really like boring slideshow a health pledge and get one swag bucks so 9 surprising facts about diabetes so I just have to click through this I’m just looking at a bunch of ads right now this is so strange it’s gonna keep it through 9 surprising facts oh you have to wait for the countdown to finish before clicking through that’s so funny so they want you to like wait now we’re on this page gotta wait 7 seconds next page there’s only six sides so I got one swag book for that let us entertain you this is a 26 minute video and you’re looking at six swag bucks you can earn up to 500 sewing bucks per day watching unique videos it’s really a lot to this one like Opinion Outpost wants nothing like this to be honest like they have way more stuff on here okay what’s this video gonna be oair plan okay kind of cool I guess klm oh this is another ad isn’t it oh I get it you have to watch night you have to watch like a series of videos everyone’s like 20 of them 500 swag bucks and we’ll get you a find on Amazon giftcard so you can get a $5 amazon you’ve heard every day but like you’re probably taking a long time considering I would have to watch like 20 minutes worth of videos for like saying this is interesting I’ll keep trying the fun see how it goes alright so now it’s Thursday I’m gonna try Opinion Outpost again see if we can get anything okay I found one so it’s only five minutes so what time did you watch TV yesterday which television stations do you watch so that little preliminary survey took like five minutes and now I can earn 5 points if I take another 10 minute survey but now I just have to select if me or any of my roommates have purchased any of this stuff replacement toothbrush heads I think it purchased like a brush so basically when you do the math five points is only fifty cents so I only got 50 cents in this eight minute survey doesn’t seem worth it to me I don’t know I’ve now been on this Opinion Outpost website for like a half-hour and gotten 50 cents alright so now it’s Friday and I’m just gonna go over the experience of this is it worth it so on Opinion Outpost i have 57 points I did seven total surveys and some of those weren’t complete somewhere like you didn’t match so 57 points pretty much translates to 5 dollars and 70 cents so let’s see what we can redeem this for so you can redeem it for PayPal cash but you have to have a hundred points Amazon giftcard I basically earned $5 and I definitely spent over an hour doing this I probably spent at least two hours maybe more taking these surveys so that is a terrible wage out really wait so that’s like 250 an hour like that’s so bad so I’ll redeem the Amazon giftcard just to check and see like if this is for real because there’s always that chance this is all a scam and like it’s not next onto swagbucks the other one that we tried halfway through the week I think swag bucks gives you more of an opportunity to earn points but their points are worth so much less that I decided early on it wasn’t worth it so I got 15 swag bucks which is basically 15 cents and obviously you can’t get anything with that okay no you can do charity donation so we’ll donate to the Humane Society this is what we’re gonna do with it 15 swag bucks donate the actual surveys though I feel like are not worth it you can get more for your time on Opinion Outpost wag bucks I would only use it for the cash back like you can play games and earn if you shop online you can earn you know so if you guys want to try it out I’ll link them down below oh swag bucks you only need to be like 13 to sign up so I think it’s really good actually if you aren’t old enough to get a job like if you’re 13 then you can make like a little bit of money from this but then once you’re at the age to get a job it just seems like you’re spending so much time for like not very much I so comment below like if there’s other sites that are better than these two that you know of or anything like that I’m very interested to see haven’t anyone else’s experience on this also you guys this is a part of my series of testing weird ways to make money online so if you haven’t seen the other ones go check them out I have tried walking dogs on a dog walking app I’ve tried flip I tried flipping clothes and I’m currently in the process of testing sweat coins which a bunch you guys commented to try yeah okay I think that’s it for this video again let me know if you tried any of them below and this video a like or dislike if you didn’t like it give it a like if you liked it and whatever if you didn’t yeah just like it I don’t care okay I will see you guys in my next video bye [Music]

HOW TO MAKE MONEY ON THE INTERNET AS A TEENAGER, YOUNG ADULT AND JOBLESS PERSON

[Music] hey guys welcome to my channel I hope you up all well I am very excited today I really wanted to do this video for a while last year I actually did a video on how not to go broke and to save money I’m gonna link that below because I really feel like it’s still super valuable but today I wanted to give you guys some tips and tricks for making money online because I know it is hard out here sometimes and I know not everyone has a job and I know that sometimes you just need to make some extra cash flow for the weekend and I feel like money something that a lot of people don’t really like to talk about I feel like it’s a little bit of a trick to kind of let those that are in the know keep known but people who don’t know are never allowed to know and I don’t think it’s fair and I think we should all eat and I think we should all grow and I think we should all be open to opportunity and information is power so today I’m gonna share what I know about making money on the internet that anybody and everybody can do so number one it’s YouTube as you can see I am a YouTube creator and I am able to make a living doing this now obviously I have quite a few subscribers we thank God but anybody can start a YouTube channel you do not need money to start a YouTube channel you do not need a network or a special account to start a YouTube channel all you need is a camera and some I DS if you’ve got any form of ideas that you feel like you want to share with the world YouTube is a great way to monetize that when I started on YouTube almost over five years ago I never made a single penny because there was no form of monetization for three years I did youtube without making any earnings but I was passionate about it so I do think it’s really important that if you are going to start a YouTube channel make sure it’s not just about making money because it’s not a quick moneymaker but it’s maybe about sharing your passions but you can definitely do that how it works when it comes to monetization is literally you make videos and there are ads that run against your videos the more people that watch your videos the more money you make on your ads it’s as simple as that you to share the money with Google I believe an Adsense and then you get a share of that money as well you can get popular videos by doing stuff that is trending like celebrity gossip or celebrity news or breaking news from wherever you are in the world as well as doing videos on products that you like maybe entertaining people what will happen is that you will have a channel and YouTube will say you I believe you’re actually able to monetize straight away when I started you had to have like two thousand views or something before you can monetize which is what I never monetize for so long but you can monetize straight away and what you’ll see is when you reach over 60 pounds you’ll begin to receive money into your bank account that you set up where your adsense account if you want more information on that you can Google Adsense and how it actually works and create yourself an adsense account after that it’s also blogging and a writing content similar to YouTube in that is you’re producing your own content based on information writing a blog is a great way to also do that and the same mechanism is Adsense as well if you write content that is relevant then you also get ads that come up beside your blog besides your written content or images and you’ll be able to make money if you want to promote that stuff then social media is a great way to do that so another way to make money is affiliate linking if there is a website that you like or a product that you like online you can use sites such as Skimlinks rewards style and I believe this one could add Network I can’t quite remember and what happens is that every time someone buys from that link it might be your auntie it might be your friend it might be your followers you are able to make a small Commission on that link now a lot of people do this on Twitter and for instance I also will say I buy this necklace from necklace from Urban Outfitters and I will share a link with you that is an affiliate link so that I make you know 20 P on you buying the necklace but if I get 20 people make doing that then how much money did I make was my calculations 20 P times 24 pounds for parents yeah I’ll make four pounds on that so I know that sounds it’s not that much money but it can actually build up you can link electronics you can link home where there’s so many things that you can link and if you like searching the web for really nice and cool product and you want to share that with your friends or your family or your social network then you can definitely do it however I wouldn’t advise just putting links out and saying buy this link I think it has to be links that are associated to what you do or what your friends and your family actually want to see from you usually a lot of these accounts work by your threshold and but I think anyone can set it up if you have a blog or an email address and then they will sign you up to their network and you will be able to log in and start sharing your links of your friends and your followers so after that if you want to make money it’s all about selling your skill if you are good at something you should try and make money on it there are sites that I like such as people per hour this is a site that I go to all the time when I’m looking for a graphic designer when I’m looking for an editor when I want a logo made or a banner made I go on to then I’ll say graphic designer and lots of people around the world are sharing their skills they’re able to make money from the comfort of their own home by providing me a service based on what they actually know how to do I’ve actually seen there are people can buy an hourly of a guy who looks like mr. t and he says happy birthday so you did it or whatever he sells that for a hundred and fifty pounds and we’ll say happy birthday Michael because he looks like mr. t if you are good at writing if you’re good at taking photos if you are good at Photoshop people are out there looking for your skills and looking for your services you can make some money while doing it and people per hour is just one of the sites that I know that does that and there may be many others and I’m also going to link everything in the description bar below so that you guys have some good insight into it so next if you can create a product it is a great way to make some money I’ve told you guys this story many times but is one of the ways that I made money when I was a teen I used to braid hair at lunchtime I myself like leave school like ten pounds each day there’s like 40 pounds a week and for a thirteen-year-old that’s a lot of money so if you have a product or a skill or something that you can sell to friends and family or to a community then make some money on it you don’t need to make 5,000 pounds every day you can make 50 pounds or 10 pounds or 5 pounds but it all adds up another site that I really like is teespring if you have a design you can create a design on teespring and then you can um sell that design so I’m thinking about doing t-shirt as I I don’t want the fuss of packaging it and sending it and doing it all myself I might just use teespring to do it so you also probably want to have like a closet clear out I’m sure you know of a bunch of stuff that you’ve got in your house or in your closet that you’re not even using anymore go through have a clear out and sell it online the pop is an app that I really like for selling clothes it’s for fashion-forward people bloggers and all that kind of stuff they’re forever on there selling stuff selling their old clothes or swapping it out so finally you can also take online surveys there are lots of different survey companies out there where people want your opinion one of the survey companies that I have talked about many times is Opinion Outpost basically all it is is companies and brands such as Amazon or Apple or I don’t know t-mobile or something lots of these different brands want to know your opinion on their product or their services and you can do this from the comfort of your bed at home basically fill in a form say how many times you use your phone a day and you can make money while doing it now somewhere like Opinion Outpost they give you vouchers gift cards coupons they also have a quarterly prize draw of $10,000 as well and it is free to join up and you can receive an email into your gmail surveys they’re in great way to make it a little bit of extra money online if you’re just like I’m sitting at home rather than wasting time on tumblr or Twitter you can be making money okay so glass I really hoped you enjoyed that video and it gave you some ideas on how to actually make some money online I know it is hard out there and I know that a lot of people don’t share this information and I have no problem sharing I think sharing is caring or need to blow it and develop and I’m definitely here for like giving all the information I have I’m also gonna be doing my live chat today I’m so excited about it it’s at 8 o’clock tonight I’m gonna link it below and I don’t know we’re gonna talk about so Nev a comment if there’s anything you know you want to talk about let me know I’m going to do it but I’m gonna see if this can be a regular thing so thank you for watching guys and I’ll see you all later [Music]

Making Money Online, Surveys and Payment Proof 2017 | Carly

hi everybody welcome to the video today um today’s video is a little different from what I have been doing but I just wanted to share this with everybody because I think it’s really awesome um lately I have been taking online surveys way more often than usual because I found a really really great site that pays pretty well for a survey site okay and they also have like payment options you can get like 200 different kinds of gift cards they have cash options which are PayPal direct deposit or a check of course and since I was a little nervous the first time I actually had them send me a check you know cuz I had physical proof to show you guys you know so the name of the site is called insta GC I’ve been on there for a couple of years now but I really didn’t start actually using site until recently like over Christmas time um and I actually got to check a payment from one survey one survey was worth $30 I’m going to show you that check in a second but I just wanted to talk about the site real quick so you know what you’re getting into if you go and try it okay it’s free to sign up first of all second of all it’s not a get-rich-quick type of thing you’re not gonna make thousands of dollars you know you’re gonna make little bits of money like um let’s say I do about five surveys every day for seven days I would probably earn anywhere from 25 to 50 bucks you know it’s not going to be tons and tons of money so don’t go into it thinking you know each survey is gonna be worth $30 or $50 that’s not really how they work um on this particular site each survey you see in the list actually has an estimated time so you’re not going to end up sitting there taking a survey for like an hour and only get paid 20 cents you know it’s not going to be like that you’re gonna know how long it’s going to take you to take the survey and how much you’re getting paid before you even click to go to the survey okay and most of the time the surveys range from 50 cents to $1 per survey and they’re usually about 15 to 20 minutes long so if you really think about it the amount of surveys that they have on there every day you could make a lot of money if you put a lot of time into it but for me I don’t have tons and tons of time um so I usually spend about an hour two hours on there you know just in my free time while I’m not doing anything else so why not make a little money right okay well here is the check I’m going to show you the tab which is actually it says right here the survey company which this is a company that’s affiliated with the site I use um a lot of their surveys show up on there um I’m just going to put my finger over my information show you so you can see there is my name okay and then there is the amount right there all right you can see the dates everything I just got this in the mail today all right so there and there there’s my wonderful thirty dollar check and again that was from only one survey so you get lucky sometimes you find surveys on there that are worth a lot more than the twenty five cent 50 cent ones um but that’s not all the time I mean you got a check you got a check back once in a while um and you’ll be able to find those like I said I got lucky finding this one and I’m always checking I go on there at least once a day just to see what’s available in the little survey tab and once in a while they have won five dollars ten dollars and they’re usually only like 15 to 20 minutes long I mean you got 20 minutes why not make a dollar you know and it’s just it’s just fun I’m kind of getting addicted to it so I hope that I kind of gave you a little insight to what this site is about if not if you have any more questions feel free to leave me some comments um ask me anything you want to ask me regarding survey sites because I have been to almost all of them and this one is probably the best one that I have found um yeah that’s about it so thanks for watching today don’t forget to subscribe and bye

5 Ways To Make Money This Summer! ☼ On The Internet

making money as a teenager doesn’t have to be hard maybe you’re planning on going to prom next year or you want to go to Europe this summer whatever you want to do it’s probably gonna cost you some money here are five ways to easily earn what you want this summer [Music] well hello people of the Internet hey guys it’s Ava and today’s video is going to be actually really cool new location this is not a permanent location I just thought with this video it’d be kind of cool to film in front of my office don’t get excited it’s literally just a corner of my bedroom today give me a cool video because I’m going to be teaching all of you guys how to make money off the internet it’s easy making money as a teenager is extremely hard I know from personal experience I’m a teenager still and it’s hard to be accepted and gets jobs as a teenager nobody wants to hire you they think that you’re not competent enough but you know what you gotta push through it me specifically I’ve learned going throughout high school that if nobody hires you you’ve got to hire yourself so it seems easy and you probably are asking Ava okay that sounds great but how am I gonna make money I got you so for today’s video I’m gonna tell you five foolproof ways that you can make money off the internet starting today does that sound awesome I’m pretty sure it does so if you guys want to learn how to make money off the internet then keep on watching so the first way to make money off the internet is for all the people that love to make crafts whatever you like to make you can do it and make money off the internet now if you’re not into online selling and having to package and ship things up selling things on your Facebook page is so easy I used to do it in high school so basically in high school I figured out that I can make really cool hair barrettes like cool pins you can tuck your hair back with and stuff and I just got stuff at Michael’s for like three dollars and I sold them on my Facebook page to people that went to my high school so all you have to do is make things in your own home take photos of it post it on your Facebook wall to all your friends and say hey I’m selling these like DIY cups for five dollars anyone want to buy them and then people will say like yeah I’ll buy them and then you’ll sell them at school pretty sure that’s illegal but I did it so I mean you know I also sold brownies on my Facebook page to people at school and whatever do was I’d make the brownies at home and then I’d package those super cute like for Mother’s Day or for maybe like an anniversary or something and I would sell them at high school so those are awesome ways to make money off the internet if you’re not into exchanging with people that you don’t know now the second way to make money off the internet is by cleaning out your closet and this is so amazing because not only number one are you making a ton of money but number two you’re cleaning your bedroom now this is kind of the same thing as the last one you can either sell your clothes online with sites like Poshmark a thread flip or something like that these sites are really amazing because then you have like millions upon millions of people that are looking at your closet and want to kind of a bargain with you it’s super easy all you do is you separate the clothes that you don’t want anymore maybe it’s something that you bought two years ago and you’ve worn it twice you separate it into a pile and you just take photos of it you post them on the site it spells it’s so easy but if you’re not into selling things to random people like I said before then you guys can also use the Facebook trick closet fails so closet sales became really popular in my high school about two years ago and basically what it is is taking photos of a bunch of clothes you don’t wear and posting them in a facebook album you can even do it on Instagram if you like really want to people will comment and be like oh well I’ll buy it at school the next day what I like to do is package them into little like shopping bags and then they fill it to them super easy making money off the internet and the third way to make money off the internet is obviously YouTube and I love YouTube because it’s not even about making the money it’s essentially doing what you love on camera and the cool thing about YouTube is that you don’t have to be a beauty guru you don’t have to be super funny if you love cars nail polish if you love shopping maybe knitting whatever you love put it on YouTube maybe it’s a hundred views you’re still getting paid for those hundred views so essentially you’re getting paid doing what you love and it’s a great thing to do just if you are bored and have a hobby you guys want to show to the world and keep in mind a lot of people don’t know this you don’t have to have ten thousand subscribers to be making money off of YouTube you can make money the second start your channel it’s so easy all you do is monetize your account bingo so the fourth way to making money online is photography and this is so much fun you don’t have to be a professional photographer to make money off of photography so to make money off of photography on the Internet there are a couple ways to doing it so the first thing is having some source of a camera it could be your iPhone camera it could be a like little point and shoot camera it could be a DSLR camera so what you’re gonna need to have to set yourself up is an Instagram page or a Facebook page for your photography and you’re also gonna want a few shots to show people so maybe just shoot a free round of shots on your friends and family first to kind of get you prepared to post them then after you have 10 of your best shots ever edited to perfection you’re gonna post those on your Facebook and on your Instagram and then the cool thing about photography is people will find your Instagram and you’ll have your little email on your Instagram about me and people who love your work contact you and be like hey so-and-so I love your photography can you shoot my senior photos can you shoot my engagement photos I don’t know what your life is and then you guys can like charge them your rate and it’s awesome people love to be photographed so if you charge them a cheap rate and you charge enough people you can make $100 easily in a week now the fifth way to making money off of the internet is so easy and it’s super easy because you can do it in your bed at night at like 4:00 in the morning instead of tumblr you could be making money so the fifth thing is online surveys and I’ve been taking online surveys since I was like a sophomore in high school just because they’re so easy the website that I use is called Opinion Outpost and basically online surveys are awesome because companies that are huge like Apple I don’t know mason jar there are huge companies out there filled with old men that don’t know anything about teenagers so if you’re a teenager and you’re in the demographic that they’re looking for maybe they need help deciding what to take out of a cell phone what to put in to answer a survey like times do text a day how many times do you touch your phone a day stuff like that that’s super easy and you’re making money off of it because you’re basically helping them develop a better company SUEZ can be taking online surveys whenever you’re bored and be winning things like money gift cards to like Amazon or your favorite stores or just credit to all of your favorite online stores and the cool thing about Opinion Outpost is that quarterly they have a ten thousand dollar giveaway prize and you can enter as many times as you want so on top of making money off of surveys you can also potentially be making ten thousand dollars what’s not to love and Opinion Outpost is free to join pretty cool so those are all of my ways to making money off the internet online and I’m gonna link all of those websites that I listed down below you guys got some inspiration on making money give this video a thumbs up and we’re all going to be rolling in the dough and just like throwing bands I make her dance [Music] if you’re a teenager likes me know that it’s not impossible to making money no matter how many times somebody tells you it is it’s not be sure to follow me on my Instagram Twitter vine account Facebook page all of those good things I love you guys I’ll talk to you guys soon oh I wish it was easier back some wallet

10 Gigabit Networking – I wanna go fast. Really, really fast.

ten gigabit networking I mean think about it transferring files around to remote pcs at speeds upwards of one gigabyte per second that’s a thousand megabytes per second well today we’re not only going to do it we are going to give you some tips and tricks that will hopefully help you out when the time comes to move to ten gigabit yourself whether it’s at work or at home and on the subject of work I thought to myself hey how about clearing some space on my desk at work by building a PC under the desk Wow drop a like on the video if you’re amped to see my upcoming desk PC build blog [Music] the mastercase 5 by Coolermaster gives you the freedom to truly make your mid-tower pc case your own with a variety of modular parts and accessories click on the link in the video description to learn more you know I still remember how mind-blowing it was like the first time that I saw something transfer over my network it 60 to 70 megabytes per second with the on-board Gigabit LAN port on some enforce board that I had then shortly afterward my mind was blown again when the PCI bus bottleneck was removed and thanks to onboard PCI Express gigabit networking I could transfer files thanks to my trusty Dimond Max 9 120 gig raid 0 boot drive and over a hundred megabytes per second Wow then for the last 10 years well it says no time has pretty much been standing still neat shirt the enterprise space is getting 40 gigabit and 100 gigabit links but it really feels like about a decade ago the entire industry had a meeting and decided that now gigabit is good enough for consumers and small businesses and let’s just leave it at that well I say no more we are using and I’m using this term fairly loosely here affordable hardware to go 10 gig at the office today it begins with the Nix that is to say network interface cards will be using Intel X 540 T twos with the only difference between it and the t1 being that it has two ports instead of well one and while any 10 gigabit card will knock the socks off of a gigabit one we chose these for two reasons one their Intel which is basically the industry standard for prosumer network cards not to mention our testing with them is gone very well and 2 because they’re both somewhat affordable at 300 bucks a pop on eBay although I got some of mine for cheaper and available in an rj45 equipped variant this is important because we wanted to use Ethernet cables rather than the expensive SFP+ connectors and direct-attached copper cables that we were using in our previous 10 gigabit setup the reason for that is that while that configuration worked well for us before starting out with PCs attached daisy-chaining to each other actually then moving up to using the backbone links on a 48 part Netgear GS 752 TX s which it doesn’t play nicely with running cabling through the walls definitely desirable for an office space and it’s not scalable and if we want to run more pcs on 10 gig at a time we need a 10 gig switch with more ports and pretty much the switch right now if you don’t want to spend an absolute fortune and you know then you might as well get sfp+ gear is the XS 7 12 T 12 port or it’s a port little brother from Netgear and those use rj45 connectors all right so it’s simple right plug into the Ethernet cables and bippity-boppity-boo your transferring files at a thousand megabytes per second right actually not quite first you’ll need to make sure that you’re using cat 6a cables if you want reliable data transfer over a reasonable distance and second and you may not have consider this but 10 gigabit is so fast that it exceeds the 6th gigabit per second limit of third-generation SATA so even if you have a wicked fast SSD drive you’ll be limited to speeds in the neighborhood of 500 550 megabytes per second and while PCI Express SSDs that overcome this bottleneck do exist I stole our Intel 750 series and put it in my personal rig so I ended up using other solution I’ve got our 24 SSD storage server on one end the one that we built in this video here and I’ve got a test bench with that 128 gigabyte kit of Dominator Platinum ddr4 from Corsair on the other end with a free and easy to use utility called soft perfect Ram disk used to treat that round like a hard drive so with such fast storage on either end it’s much easier to evaluate the performance of the actual network link which frankly didn’t go so hot on the first kick at the county I don’t know who these people getting perfect 10 gig performance out of the box are or how many horseshoes they had to put up their butts to make them so damn lucky but I was seeing this weird cap at around 300 to 350 megabytes per second now to be clear that is still a significant improvement and already well worth the upgrade for our purposes but I wanted more den and I paid for more and thanks to an amazing series of posts on thus innovate blog which you should definitely check out we can link them below the video I was able to do much better than that mostly so the first tip from them was this great tool called NTT TCP that has a command-line interface so not the friendliest thing but that they simplified by basically showing you where to plug in the program install path and machine IP addresses and boom it’s off to the races so this tool revealed that my two machines were capable of more than one gigabyte per second performance between them so what gives well time to dig into the event settings to see if there’s anything that we can tweak I started by enabling jumbo packets on all clients involved in the transfer and on my network switch side note here it doesn’t seem to matter if the values don’t match up exactly as long as your switch is set to something higher than your NICs so this means that now effectively the data packets sent back and forth are bigger which is better for a high speed transfer of large files next I tweaked receive side scaling a feature that leverages more CPU cores for network transfers and I set it to match the settings with my number of logical processors on my pcs so 16 on my 59 60 X test bench 8 on my 6700 K test bench and 16 on my Xeon server and finally I increased the size of both the send and receive buffers to their maximum this increases memory usage but can yield extra performance so then what did I get well performance wise over the original numbers in ntt TCP not much but my real-world transfers were much higher in fact more higher than they should have been but I’m not gonna complain and I was seeing sustained speeds of over double my original transfer rates with that said not all is necessarily rosy and for whatever reason maybe some of you sharp people out there can go and contribute your comments below some transfers are faster or slower than others so I ended up actually putting together two test benches with brand spanking new installations of Windows 10 and Windows Server 2012 r2 just for the sake of trying to eliminate as many variables as possible I was still running into weirdness where one machine with a particular OS would saturate the connection writing to the Wanek SSD server but then be capable of half or 60% of that speed when reading from it and then another would saturate on reads and then limp along writes I mean that’s the one you’re looking at here by the way but as snake-bitten as I seem to be when it comes to networking stuff limping along in this case is still 500 plus megabytes per second so I guess I’ll just have to deal with my 34 gigabyte file transferring a little slower than it otherwise would overall very happy with the results and speaking of being happy with the results Squarespace if you were thinking to yourself gee I’d like to build myself a website but I sure don’t want to be unhappy with the results BAM pick out a template on Squarespace customize that template to build yourself whatever it is you’re trying to build yourself you want to build a store a company website on you know menu a blog portfolio use their simple templates and their powerful creation tools and their 24/7 tech support and it starts at only $8 a month so it’s affordable and you won’t break the bank and sure I have more talking points but I think you guys pretty much get the point you want to build an easy to use reliable website Squarespace com they’ve got a free trial which you can sign up for two day and then if you end up liking the site that you create you can look into their affordable plans pretty freakin awesome there’s no credit card required by the way to try out the trial so pretty

Computer Networks: Crash Course Computer Science #28

hi I’m Kerry Ann and welcome to crash course computer science the Internet is amazing in just a few keystrokes we can stream videos on YouTube hello read articles on Wikipedia order supplies on Amazon video chat with friends and Suites about the weather without a doubt the ability for computers and their users to send and receive information over a global telecommunications network forever change the world a hundred and fifty years ago sending a letter from London to California would have taken two to three weeks and that’s if you paid for express mail today that email takes a fraction of a second this million fold improvement in latency that’s the time it takes for a message to transfer juiced-up the global economy helping the modern world to move at the speed of light on fibre optic cables spanning the globe you might think that computers and networks always went hand-in-hand but actually most computers pre-1970 were humming away all alone however as big computers started popping up everywhere and low-cost machines started to show up on people’s desks it became increasingly useful to share data and resources and the first networks of computers appeared today we’re going to start a three-episode arc on how computer networks came into being and the fundamental principles and techniques that power them [Music] the first computer networks appeared in the 1950s and 60s they were generally used within an organization like a company or research lab to facilitate the exchange of information between different people and computers this was faster and more reliable than the previous method of having someone walk a pile of punch cards or a reel of magnetic tape to a computer on the other side of the building which was later dubbed as sneakernet a second benefit of networks was the ability to share physical resources for example instead of each computer having its own printer everyone could share one attached to the network it was also common on early networks to have large shared storage drives ones too expensive to have attached to every machine these relatively small networks of closeby computers are called local area networks or lands and LAN could be as small as two machines in the same room or as large as a university campus with thousands of computers although many land technologies were developed and deployed the most famous and successful was Ethernet developed in the early 1970s at Xerox PARC and still widely used today in its simplest form a series of computers are connected to a single common Ethernet cable when a computer wants to transmit data to another computer it writes the data as an electrical signal on to the cable of course because the cable is shared every computer plugged into the network sees the transmission but doesn’t notice the data is intended for them or another computer to solve this problem Ethernet requires that each computer has a unique media access control address or MAC address the unique address is put into a header the prefix is any data sent over the network so computers simply listen to the Ethernet cable and only process data when they see their addressing the header this works really well every computer made today comes with its own unique MAC address for both Ethernet and Wi-Fi the general term for this approach is carrier sense multiple access or CSMA for sure the carrier in this case is any shared transmission medium that carries data copper wire in the case of Ethernet and the air carrying radio waves for Wi-Fi many computers can simultaneously sense the carrier has the sense and multiple access and the rate at which the carrier can transmit data is called its bandwidth unfortunately using a shared carrier has one big drawback when network traffic is like computers can simply wait for pilots on the carrier and then transmit their data but as network traffic increases the ability that two computers will attempt to write data at the same time also increases this is called a collision and the data gets all garbled up like two people trying to talk on the phone at the same time fortunately computers can detect these collisions by listening to the signal on the wire the most obvious solution is for computers to stop transmitting wait for silence and then try again problem is the other computer is going to try that too and other computers on the network that have been waiting for the carrier to go silent will try to jump in during any pause this just leads to more and more collisions seeing everyone is talking over one another and has a backlog of things they need to say like breaking up with a boyfriend over a family holiday dinner terrible idea Ethernet had a surprisingly simple and effective fix when transmitting computers detects a collision they wait for a brief period before attempting to retransmits as an example let’s say one second of course this doesn’t work if all the computers use the same wait duration they just collide again one second later so a random period is added one computer might wait 1.3 seconds while another weighs 1.5 seconds with any luck the computer that waited 1.3 seconds will wake up find the carrier to be silent and start transmitting when the 1.5 second computer wakes up a moment later it’ll see the carrier’s in use and will wait for the other computer to finish this definitely helps but doesn’t totally solve the problem so an extra trick is used as I just explained if a computer detects a collision while transmitting it will wait one second plus some random extra time however if it collides again which suggests network congestion instead of waiting another 1 second this time it will wait 2 seconds if it collides again it will wait 4 seconds and then 8 and then 16 and so on until it’s successful with computers backing off the rate of collision goes down and data starts moving again freeing up the network family dinner saved this backing off behavior using an exponentially growing wait time is called exponential back-off both Ethernet and Wi-Fi use it and so do many transmission protocols but even with clever tricks like exponential back-off you can never have an entire University’s worth of computers on one shared Ethernet cable to reduce collisions and improve efficiency we need to shrink the number of devices on any given shared carrier what’s called the collision domain let’s go back to our earlier Ethernet exam Paul where we had six computers on one shared cable aka one collision domain to reduce the likelihood of collisions we can break this network into two collision domains by using a network switch it sits between our two smaller networks and only passes data between them if necessary it does this by keeping a list of what MAC addresses are on what side of the network so if a one’s transmitted to see the switch doesn’t forward the data to the other network there’s no need this means if he wants to transmit two F at the same time the network is wide open and two transmissions can happen at once but if F wants to send data to a then the switch passes it through and the two networks are both briefly occupied this is essentially how big computer networks are constructed including the biggest one of all the infinite which literally interconnects a bunch of smaller networks allowing Internet work communications what’s interesting about these big networks is that there’s often multiple paths to get data from one location to another and this brings us to another fundamental networking topic routing the simplest way to connect two distant computers or networks is by allocating a communication line for their exclusive use this is how early telephone systems work for example there might be five telephone lines running between Indianapolis and Missoula if John picked up the phone wanting to call Hank in the 1910s John would tell a human operator where he wanted to call and they’d physically connect John’s phone line into an unused line running to Missoula for the length of that call that line was occupied and if all five lines were already in use John would have to wait for one to become free this approach is called circuit switching because you’re literally switching whole circuits to route traffic to the correct destination it works fine but it’s relatively inflexible and expensive because there’s often unused capacity on the up side once you have a line to yourself or you have the money to buy one for your private use you can use it to its full capacity without having to share for this reason the military banks and other high importance operations still buy dedicated circuits to connect their data centers another approach for getting data from one place to another is message switching which is sort of like how the postal system works instead of a dedicated route from A to B messages are passed through several stops so if John Y is selected to Hank it might go from Indianapolis to Chicago and then hop to Minneapolis then Billings and then finally make it to Missoula each stop knows where to send it next because they keep a table of wet past letters given a destination address what’s neat about message switching is and it can use different routes making communication more reliable and fault tolerant sticking with our mail example if there’s a blizzard in Minneapolis grinding things to a halt the chicago mail hub can decide to route the letter through omaha instead in our example cities are acting like network rooters the number of hops our message takes along its route is called the hop count keeping track of the hop count is useful because it can help identify routing problems for example let’s say Chicago thinks the fastest route to Missoula is through Omaha but Omaha thinks the fastest route is through Chicago that’s bad because both cities are going to look at the destination address Missoula and end up passing the message back and forth between them endlessly not only is this wasting bandwidth but it’s a routing area that needs to get fixed this kind of error can be detected because the hop count is stored with the message and updated along its journey if you start seeing messages with high hop counts you can bet something has gone awry in the routing this threshold is called the hop limit a downside to message switching is that messages are sometimes big so they can clog up the network because the whole message has to be transmitted from one stop to the next before continuing on its way while a big file is transferring that whole link is tied up even if you have a tiny 1 kilobyte email trying to get through and either has to wait for the big file transfer to finish or take a less efficient route that’s bad the solution is to chop up big transmissions into many small pieces called packets just like with message switching each packet contains the destination address on the network so reaches know where to forward them this format is defined by the Internet Protocol or IP for short a standard created in the 1970s every computer connected to a network gets an IP address you’ve probably seen these as 4 8 bit numbers written with dots in between for example 1 7 2.2 17.7 dot 2 3 8 is an IP address for one of google’s servers with millions of computers online all exchanging data bottlenecks can appear and disappear in milliseconds network routers are constantly trying to balance the load across whatever routes they know to ensure speedy and reliable delivery which is called congestion control sometimes different packets from the same message take different routes through a network this opens the possibility of packets arriving at their destination out of order which is a problem for some applications fortunately there are protocols that run on top of IP like TC PYP they handle this issue we’ll talk more about that next week chopping up data into small packets and passing these along flexible routes with spare capacity it’s so efficient and fault tolerant it’s what the whole internet runs on today this routing approach is called packet switching it also has the nice property of being decentralized with no central authority or single point of failure in fact the threat of nuclear attack is why packet switching was developed during the Cold War today roof is all over the globe work cooperatively to find efficient routing –zz exchanging information with each other using special protocols like the internet control message protocol ICMP and the border gateway protocol BGP the world’s first packet switch Network and the ancestors of the modern Internet was the ARPANET named after the u.s. agency that funded it the Advanced Research Projects Agency here’s what the entire ARPANET looked like in 1974 each smaller circle is a location like a university or research lab that operated a Reuter they also plugged in one or more computers you can see PDP ones IBM system/360 and even an atlas in london connected over satellite link obviously the internet has grown by leaps and bounds in the decades since today instead of a few dozen computers online is estimated to be nearing 10 billion and it continues to grow rapidly especially with the advent of Wi-Fi connected refrigerators thermostats and other smart appliances forming an Internet of Things so that’s part one an overview of computer networks is it a series of tubes well sort of next week we’ll tackle some higher-level transmission protocols slowly working our way up to the world wide web I’ll see you then crash course computer
