海外TECH	DEV Community	Decoupled Microservices Architecture with Materialize	https://dev.to/bobbyiliev/decoupled-microservices-architecture-with-materialize-2l67	Decoupled Microservices Architecture with Materialize IntroductionThere are several ways to handle data in a microservice architecture in this article we will cover the approach of having a separate database for each microservice PrerequisitesThis article will build upon the concepts covered in the following video by Houssem Dellai Data in a Microservice Architecture Architecture overviewWe will use the following architecture as described in the video above The following diagram shows the architecture Quick overview of the architecture We have an eCommerce website that consists of these two microservices Catalog Service This microservice is responsible for managing products Basket Service This microservice is responsible for managing orders Both microservices are behind an API Gateway Each microservice has its own database In order for the Backend to communicate with the Catalog service we use a REST API This is how the Basket service gets the products data from the Catalog service The problem with the above architecture is that the Basket service is tightly coupled with the Catalog service There are a few drawbacks to this architecture If the Catalog service is down the Basket service will not be able to get the products data Meaning the Basket service will not be able to process orders and would also be down When scaling up the Basket service will start generating load on the Catalog service meaning the Catalog service will also need to be scaled up Each time the Catalog service is updated the Basket service will need to be updated as well To decouple the microservices we will use a third microservice called Gateway This microservice will be responsible for routing the requests to the other microservices But with this approach the API Gateway will handle all the requests and the microservices and this could turn into a bottleneck as it will have a lot of responsibilities Let s take a look at another approach to decouple the microservices Loosely coupled microservicesAs each microservice is independent and owns its own data to decouple the microservices we can use a materialized view that will store the aggregated data of the microservices The following diagram shows the architecture with the materialized view Quick overview of the architecture above We are adding a new materialized view to the Basket service which will store the aggregated data of the Basket service and the Catalog service The Catalog service is now extended to send change events to the Basket service The change events could be stored in a service like Apache Kafka or RedPanda The Basket service will now handle the change events and update the materialized view accordingly as the data in the Catalog service changes The materialized view will be used as a read only data source for the Basket service The downsides of this approach are There will be a duplicate of the data in the aggregator The change events would add lots of complexity to the microservices If you do not have the expertise adding the additional components and changes means that there will be a steep learning curve for the development team Using MaterializeMaterialize is a streaming database that takes data coming from different sources like Kafka PostgreSQL S buckets and more and allows users to write views that aggregate materialize that data and let you query those views using pure SQL Unlike traditional materialized views Materialize is designed to maintain the data in a continuous state and keeps the views incrementally updated This means that if you have a view that is constantly updating you can query the data in real time A normal materialized view would do a full table scan every time it needs to be updated which can be very expensive For a more detailed explanation of Materialize please see the Materialize Documentation You can also take a look at this quick video that explains what Materialize is Decoupled Microservices Architecture with MaterializeThanks to Materialize we can decouple the microservices architecture and use a live materialized view to store the aggregated data Materialize will keep the materialized view incrementally updated and will allow us to query the data in real time with subsecond latency This will eliminate the need for the event driven architecture and will also eliminate the need for extending the Catalog service to send change events to the Basket service The following diagram shows the architecture with Materialize Quick overview of the architecture using Materialize We will again use a materialized view to store the aggregated data of the Basket service and the Catalog service This time we will use Materialize to store the data As this will provide us with a real time view of the data we no longer need the change events as we can query the aggregated data in real time That way if the price of a product changes the Basket service will be aware of the change immediately As Materialize is Postgres wire compatible we don t need to use any third party libraries to use Materialize and there is no learning curve One thing that you need to keep in mind is that as of the time being Materialize does not have persistence This means that if you restart the service the materialized view will need to re aggregate the data This feature is on our roadmap and will be available soon DemoTo put this into practice you can take a look and run the following demo How to join MySQL and Postgres in a live materialized view ConclusionUseful links Materialize DocumentationMaterialize DemosMaterialize CloudMaterialize GitHubMaterialize

海外TECH	DEV Community	Should You do a Bootcamp in 2022?	https://dev.to/peterlunch/should-you-do-a-bootcamp-in-2022-3dan	Should You do a Bootcamp in Coding bootcamps were popping off in the early s Bootcamp graduates were landing jobs with fat K salaries And many were doing this in weeks or less It seems like every bootcamp graduate you talked to was working at places with ping pong tables and free food It s now the s and you want to be a big time developer who makes a fat salary You want to get paid to do something you love So you think you ll do a bootcamp But then you peep the K price tag You start wondering are bootcamps still good Can you still make a big time salary Are all the things that were true a few years ago still true in And if they are should you do a bootcamp in The answer is it depends Lame I know But it really does depend on a few factors This post is going to tell you what those factors are to help you decide if you should still do a bootcamp in Treat the post like a choose your own adventure Skim the headings and read the sections that are relevant to you If you read the whole thing it will tell you what a bootcamp is how to decide if a bootcamp is right for you the bad parts of a bootcamp the good parts and the alternatives Alright let s get into it If you are a person who thinks a bootcamp is doing exercise in a park with a bunch of strangers read on to find out what a coding bootcamp is and why you might want to do one What is a Coding BootcampA coding bootcamp is a short intensive course that aims to teach you the bare minimum you need to find your first developer job This is an important point to take note of Why Because coding bootcamps won t teach you everything you need to know Some of it you are going to have to learn yourself and some of it you are going to have to learn on the job This important factor to acknowledge and we ll go into it more later For now just know bootcamps aim to teach you to code quickly These coding bootcamps can also be online only in person or a mix of the two All of them should offer live teaching instructors and a structured program They are not pre recorded video courses you might buy off Udemy where you have no access to the instructor Types of BootcampsThere are many types of coding bootcamps and they can focus on a range of different technologies It could be a data science bootcamp or maybe a web development bootcamp What interests you will determine what type of bootcamp to do When looking at the types of bootcamps I think the best way to look at them is cost and ownership structure Here are the types to help you search Privately owned local bootcamps think your little hometown bootcamp put together by local people University Bootcamps often these aren t run by the University but are actually run by private for profit companies who want to leverage the Universities brand Non for profit bootcamps run for free very rare  But Leon Noel is running one now Privately owned bootcamp chains like Generally Assembly Le Wagon or Lambda School Now you know what coding bootcamps are and aren t let s look at the factors you should consider before deciding if you should do a bootcamp Factors to ConsiderIdeally you want to give a bootcamp everything you have You want to be able to dedicate your time and energy towards learning to code Doing this will mean you can get the most out of the bootcamp It will also give you a higher likelihood of being successful in finding a job Bootcamps are not easy They will challenge you and ask a lot of you Just having a teacher and structure won t make things easy A lot of people think they can just sign up half ass it and get a job in the end Unfortunately it doesn t work like that This next section looks at some factors you should consider if you re not sure if you should do a bootcamp You want to consider these Because if you acknowledge these factors then you are more likely to be able to immerse yourself and be successful during your time in the bootcamp Do You Know if You Enjoy Coding Have you tried to code Do you even like it If you answered no to either of these  Do not do a bootcamp  You can stop reading here Why Because bootcamps are tough You will be battling to keep up with the material covered Most likely you are going to have to work a lot of hours on nights and weekends I probably averaged hours a day on weekdays and hours on weekends This is how they squeeze year s worth of material into weeks because they force you to do a lot of work outside of class Ouch So if you don t want your money to go to waste you need to work your ass off Therefore if start the bootcamp without having ever written one line of code you re going to be in real trouble There are two reasons for this First if you haven t ever coded how do you know you ll enjoy it If you don t enjoy it your probably not going to get through the bootcamp or you might not get through your first year in the industry To use an analogy let s say you don t enjoy exercise Now say you sign up for a marathon where you had to run it in hours How likely are you to train to do that marathon And even if you run it how likely are you to finish in under hours I d say it is a low likelihood for most people The same applies to bootcamps trust me I ve seen it Now I m not saying you have to like what you do Plenty of people I ve worked within the past hated what they did they suffered through it because they had mouths to feed But unless you re incredibly driven it s going to be hard to do those hour days for weeks Hard but not impossible You need to decide The next reason you should try coding before you start a bootcamp is a lot of bootcamps have pre work for you to do Anyone in my bootcamp who didn t do the pre work was toast They either dropped out or struggled through the bootcamp and are now not working in tech This is a dirty little secret of bootcamps where you need to know a bit about coding before you start otherwise you won t survive You ll always be behind Now if you re always behind that means your peers who you are competing with for jobs will be ahead of you technically Meaning finding that first job just got harder So I d recommend you try some free resources I ve linked below to find out if you actually enjoy coding Can You Commit Financially Damn money was tight during my bootcamp and I m saying this as someone who was a tight arse during the bootcamp I was rolling into class with packed peanut butter and jelly sandwiches something I hadn t done for years Despite this I still nearly ran out of money before I landed my first job So you need to ask yourself can you commit financially When you sign up to do a bootcamp unless it s part time you re probably not going to be working So that K you are investing is actually the cost of the bootcamp plus the opportunity cost of the money you could be earning In my case my bootcamp actually cost me K because I was giving up K in money I could have earned in my job Now I m betting that I will make it back over my career But it is definitely something to consider Especially if you think you can learn and find a job in your spare time Real Cost of Bootcamp Bootcamp K Loss income K Cost of living per monthTotal Cost K K x per month KYou also need to consider how you will pay your bills The bootcamp cost K What about all your other expenses that still exist while you re doing the bootcamp I mean a man s gotta eat There were a few people in my bootcamp who didn t really factor this in and it added further stress to an already stressful time Another thing to consider is that you might not get a job right away I know it took me about months until after my bootcamp to land a job I moved cities at that time which complicated things This was pretty common for about thirds of my cohort who even got jobs So your calculations should also factor in some post bootcamp buffer you need a strategy for how you are going to survive a bit longer while you job hunt So make sure you have those dollars in the bank to handle your bills before you sign up to do a bootcamp otherwise you re going to have a bad time Do you Have Time This section might be better worded as do you have time and are you willing to put in the time Like I ve mentioned bootcamps are massive time investments they aren t just the hours of lessons you have They are all the other hours at night and on weekends that you need to be spending on getting yourself job ready So you need to consider this two ways The first is do you actually have time Do you have a partner like me who was understanding and knew that I would be fully immersed in this thing of my waking time for the next weeks Do you have other commitments that you can t ignore Then you need to ask yourself Honestly ask yourself if you can give the time needed to be successful at your bootcamp It takes a lot of sacrifice The other way to consider this is are you willing to work hours a day and work on your weekends I love my weekends those mothers are sacred But during my bootcamp I knew I d have to give them up I was willing to get up bleary eyed on a Saturday morning after a night crying over bugs in my code to do it all again You have to ask yourself are you willing to do that also Because during my bootcamp there was very little time for the things I liked I didn t play video games I didn t read non coding related things I only managed episodes of the Office a night It was tough Worth it but tough Now not everyone will have to do what I did Some of you will be able to get by on hours some on But even if the lessons click quickly for you I d still argue you need to be ready to dedicate a lot more time than you think to the bootcamp because I d argue and from experience I know weeks just isn t enough to make you a good developer Therefore the more work you put in the easier it will be to transition Bootcamps are a sacrifice of your time consider if your life will allow you to do that If not that is okay there are other avenues for you to achieve your dream What Jobs are Available in Your Local Area This is probably less relevant in a remote post covid world But it is still worth mentioning because I think some businesses are still hesitant to hire people outside of their local area So the more businesses that could potentially hire you means more chance of getting hired Therefore you need to do some research into what jobs in software development are being advertised in your local area Do some research by searching sites like Indeed and LinkedIn for jobs in your area Use terms like junior developer entry level developer and associate developer to see how many results are in your area When you re looking at jobs have a look at the languages they are using If the languages are mostly in something you won t be learning then consider if that will prevent you from finding work Because if your bootcamp teaches Ruby and Vue and there are only React and Python jobs in your area you might struggle to find a job Think of it this way if you were hiring someone who you know you re going to have to train anyway wouldn t you want to make life easier by ensuring they have experience with the languages you use It s kind of like an electrician trying to get a job as a plumber Yeah they are in similar areas but they have a lot longer to go than another plumber You also need to remember you won t just be competing with people in your bootcamp you ll be up against community learners I always thought the term self learner is dumb you didn t just start teaching yourself You used resources someone else made to learn rant over people with some experience and university graduates So not many jobs might mean you re going to have a harder time finding one It s not impossible to get a job in another tech stack but your chances of finding a job will probably increase if you know at least some of the potential employers programming languages So research what is available locally Are Your Skills Already too Advanced for a Bootcamp If you ve been coding for a while Especially if you have been coding with the tech stack that you re going to be learning in the bootcamp You might already be too advanced for the bootcamp The quickest way to find this out is to apply for some developer jobs You ll need to know how to get past the automated resume readers But once people start looking at your resume the market will give you some indication of if you re employable or not If you find that you re getting calls for interviews and you re passing the tech tests Then you probably don t need to spend the money for a bootcamp You just need to work on interviewing and solving tech tests until someone gives you your first break Considering all the FactorsSo those are the factors to consider when thinking if you should do a bootcamp If I had to answer every single Reddit thread asking whether they should do I bootcamp with one answer I would say this “If you enjoy coding have enough money squirreled away enough time and feasible opportunities to find work then I d recommend you do a bootcamp If this sounds like you then read on to see my methods for determining if a bootcamp is any good How to Tell if a Bootcamp is Actually GoodAlright so you ve decided a bootcamp is for you Yay That is great you can stop asking Reddit if you should do one Now you need to figure out if the bootcamps you re interested in are actually good But how do you do that Well below are some tips to help you do just that Use these to get a feeling for if the bootcamp can actually deliver what they are promising on their landing page Don t Read ReviewsYou ve probably already read some reviews for the bootcamps in your area But the thing to remember with reviews is that they tend to be biased either to really positive or really negative takes I don t know about you but I ve never left a review for a product in my life especially not a product I was just satisfied with In fact I d heard from other bootcamp alumni that some bootcamps make writing reviews a mandatory in class exercise which is very suss So my advice would be to ditch reading reviews Instead follow the steps below However if reading reviews is your only option it s not there is one trick I have up my sleeve and that is to search two other places Type into Google site reddit com bootcamp name then read peoples threads Go to Twitter s advance search  then enter the bootcamp name in the “Words sections “exact phrase box and down under the engagement section in the “minimum replies box enter “ Then hit the “Latest tab This will help you get a sense of what people are saying about the Bootcamp and it is less likely to be coerced However scrape reviews and follow the steps below to find out if the bootcamp is actually worth the money Do Some LinkedIn ResearchLinkedIn is such a great place to learn more about the bootcamps you are considering You can see all kinds of things things that the bootcamp might not tell you or that they want to hide with clever statistics we ll look at this in a little bit Here are some things you should be researching on LinkedIn before you get going How many past alumni are actually working in the field the bootcamp was preparing them for You can do this by typing “ into the search bar →clicking the people filter →all filters →school →typing the school you are interested in →then filter for your area You can then click into people s profiles and see where they are actually working How many past alumni are hired as mentors students Where alumni tend to get work after the bootcamp How long it took them to get the job Check this against the time the bootcamp finished and the time they listed as when they started their job This will give you a good indication of what is actually happening with past students and not what the bootcamp is telling you happens However the next step is the most important one you can take to help you determine if the bootcamp is actually good Reach out to past alumniThis is the single best thing you can do to find out if a bootcamp is good Now that you ve done some LinkedIn research it s time to reach out to some of the alumni Preferably you want to speak to recent graduates Why is this the best thing you can do Because those alumni are the best way to find out what to expect from the bootcamp You get to ask them questions that let you dig deeper than reviews and LinkedIn research Now you might be saying why would they respond to you They will respond because they ve been in your shoes and most people want to help Not everyone will reply but if you follow the steps below you ll have a good chance of getting some replies To reach out to alumni you can message them on LinkedIn and ask if they have time to chat about their experience at the bootcamp Pro Tip Go to their portfolio website since most bootcamps make you make one once there just grab their email or use their contact form to reach out to them You re more likely to get a reply this way Here is the template I used to reach out to them Using this I got about an reply rate to all the emails I sent out Hi X I found your details from your website after I sawyou were an alumni of bootcamp name I reallyliked say something nice about their portfoliothey worked hard on it I was wondering if I could ask you a few questionsabout your experience with the bootcamp As I amconsidering it but I wanted to speak to a fewalumni before I commit I can shoot the questions to you over email ifthat is easiest Let me know if you have time and I can send questions your way or book a quick minute chat Cheers Your Name If they agree to a face to face chat make sure in your follow up email you make it as easy as possible for them to chat with you What I mean by this is offer them a few options for times to meet like so That is amazing I really appreciate it Are you free on these days Wednesday between pm pmand Thursday Between am pm If you are just let me know the time and send you acalendar invite for a quick minute Zoom call Then all you need to do is actually ask them for their opinions of the bootcamp Here are the questions I asked What did you enjoy about the bootcamp Were there any students you know that didn t enjoy it why do you think they didn t enjoy it Were the teachers what you expected Knowing what you know now about the bootcamp would you do it again How hard was it to find a job after the bootcamp How many people in your cohort didn t find jobs Feel free to ask other questions the point is you are trying to get real authentic answers where the person isn t incentivized by sales to give you only positive answers Also try to keep in touch with this person if you decide to do the bootcamp Update them on your progress who knows they might be able to help you get a job at the end if you show initiative If you re still not sure after you ve reached out to alumni there are a few other things you can check to help you decide if you should do a bootcamp Check How Old the Bootcamp isI don t think the age of a bootcamp is necessarily an indicator as to whether a bootcamp is good or not Bootcamps are essentially the people teaching it If a teacher leaves then you re going to have a very different experience from the last cohort However there are a few things that age can help you understand when trying to determine whether the bootcamp is good or bad Older bootcamps will have employment statistics most advertise them but others will provide them if you ask for them If they don t provide them this is a red flag You can also check these statistics against some of the LinkedIn research you did just a quick eye test will do the trick Older bootcamps will also have alumni so make sure you take advantage of the step above For newer bootcamps you are going to be taking a risk if this is their first run A few things you can do to reduce that risk are Look up the teachers on LinkedIn and Twitter and have a look at their experience and what they tweet about Ask the bootcamp a lot of questions things like how they plan to support you post study the structure of the course etc If they struggle to give answers this could show they aren t prepared Don t write off newer bootcamps they all had to start at cohort Sometimes it s an advantage as their best marketing tool is you so they will want to make your experience as good as possible so they can attract future students Just recognize the risk and decide if you are willing to take that risk It s not for everyone Talk to the BootcampThe last step and one you should do is to talk to the bootcamp If Coivd permits go talk to them on campus and meet them face to face I find face to face I get a better gut feel for if something is right for me When you meet them ask them all the questions you have following on from your meetings with alumni It is okay to say things like “past alumni I spoke to said don t give them their name they didn t think you did x amp y well How are you planning on fixing it This step is about clarifying things and feeling out the place You want to suss out if you like the vibe are these people you want to spend the next weeks with Because you ll be spending a lot of time with them and personally I like to spend my time with people I like I sort of used this step to get a feel for fluffy things like the vibe and culture It was so I could get a gut feel if it felt right Do Your ResearchAt the end of the day the best way to decide if a bootcamp is worth your money is to do the research You have to go beyond the reviews and try and speak to real people There is no full proof way to ensure that the bootcamp will deliver what it says on the box As I mentioned so much depends on the teaching staff However if you do the research you ll empower yourself to make the best decision from the options you have If you take one thing away from this section please make it the part where you reach out to alumni I spoke to multiple alumni at different bootcamps and it made my decision so much easier What Bootcamps Won t Tell You the Full Truth About Student Employment RatesBootcamps manipulate these and boost them in sneaky ways So make sure you read the fine print Here are some ways they do it you should watch out for these Some bootcamps will have fine print that shows the employment rate of employees who found a job within months months is a long time can you be jobless for months or are you dedicated enough to learn for months Another misleading way a bootcamp might manipulate these figures is they hire their former students They hire them to be mentors or teachers assistants and pay them minimum wage This way they can include them in the employed column Also watch out for bootcamps that classify students that got jobs in non course related fields or doing very low level tech things like tech support “have you tried turning it off and on again type stuff So make sure you don t just look at the big number Dig into those numbers and check the fine print Bootcamps can be really sneaky Employers Don t Really Care if you Went to a BootcampYep you read that right The fact that you went to a bootcamp doesn t really carry much weight What employers actually want are tangible skills Skills like can you really code in the languages your resumes say you can They ll determine this from your projects and things like coding tests The bootcamp helps you actually get better at those languages and pushes you to make projects But it won t mean much at the end of the day So if you are going to a bootcamp because you think their cute little certificate will get you a job you re going to have a bad time The Time it Takes to get a Job and Salary ExpectationsMost people don t just go from the bootcamp straight into a job Many will finish the bootcamp and then look for jobs So don t get swept up in the claims a bootcamp makes We talked about bootcamp hiring stats so recognize it can take time to find a job It can take people anywhere from months post the bootcamp to find their first developer job Some may never find a job Also temper your salary expectations Lot s has changed since bootcamps started and people were getting paid K straight out of a bootcamp Bootcamps like to show off the big salaries people get but they might have been from years ago Check the data on that I d argue the average salaries are even bogus Be skeptical are you going to share you got K after you finished your bootcamp if someone else got K Would you share it at all If the sample is it s not worth much Salary can be really dependent on the location of the bootcamp and therefore the cost of living If the Bootcamp is in San Fransisco grads will earn more but their cost of living is higher than say someone living in Ohio I think in this situation it is better to be pessimistic rather than optimistic It is also why it is really important to speak to alumni of bootcamps they can give you some hard truths Learning is Surface LevelA bootcamp is too short of a time frame for you to truly understand the concepts It is going to take you a while to understand how things really work A bootcamp will pitch to you that you will know x y and z technologies by the end of the bootcamp But in reality you ll know just enough to be employed You re going to have to work on the rest when you start working This can feel really uncomfortable you ll probably feel like an imposter However coding is almost a never ending pursuit of learning Even the Seniors in my team are constantly remarking how they learned something new So it s okay that the learning is just surface level you just have to be prepared to keep learning after the bootcamp is finished Are you okay with learning continually because if not the bootcamp is not like an accounting degree where you ll have most of your learning done in the degree You need to be ready to continue learning at a rapid pace when you first start your new job Payment StructureIt s important to know that not all bootcamps have the same payment structure The payment structure I want to point out is “Income Share Agreements or ISAs which let you attend a bootcamp for low upfront costs Now I think ISAs get a pretty harsh wrap At the end of the day an ISA is an agreement between two adults It s up to the individual to read the fine print And for some it is their only option That said they can still be pretty confusing so let s go through them ISA s are in most cases agreements that don t require you to pay much upfront Instead you pay it back once you have a job and that money is automatically taken from your paycheck The amount taken is a percentage of your salary and it comes out every month for a set period This is an important point to note The amount is over a set period usually years It doesn t stop once you hit a certain amount So say your agreement is over years at and your first job is per year It would look like this years total paidThat is a lot of money you are paying Double And some compared to a K bootcamp Also if your pay goes up during that time it will cost you more Now some ISA s have a cap A max amount you can pay At the end of the day it s up to you to do your research on potential ISAs You need to factor in if you can live on your salary minus the percentage from the ISA Benefits of Doing a BootcampThere are a lot of benefits to doing a bootcamp aside from learning how to code with a teacher I wanted to detail these because I think sometimes the “yOu can lEarN It fOr fReE crowd can neglect these intangibles After all we re not all superhuman discipline machines like them You Put Your Money Where Your Mouth isYou spent K on the program I don t know about you but if I spend that sort of money I m damn well going to show up every day When you do a bootcamp you have in person hours where you come in and learn and work Even if you just do the hours of class time that is hours per week that you are dedicating to learning to code I found it very difficult to find hours a week when I was learning from home I think this happens for a few reasons Friends amp Family understand that you are all in and that this is a temporary change for you Therefore they are more likely to be less demanding of your time You won t have unexpected things at work come up that disrupt your time and force you to miss hours you could be coding You have peer pressure to do that work and show out You paid all that money you re less likely to say you re too tired to code or that you ll do double time on the weekends Money is a great motivator It can really light a fire under you I know it certainly did for me Accelerates Career ChangeBootcamps will speed up the process of changing careers They have to by the very nature of you being all in When you re in a bootcamp you are coding every day and flying through topics Even though the learning is surface level it is very unlikely you would achieve the same results over the same period if you were learning part time Bootcamps are also structured This means you don t waste time thinking about what project you should build and what technologies you should use you are told all of this Not having to spend energy on this stuff means you get to spend all your energy on learning You won t get that feeling of okay I finished this thing what should I do next You finish one thing and then are pushed right into the next thing during your bootcamp This acceleration will also force you to learn how you learn best This skill will be very valuable when you get into your first job You re going to need to use it time and time again as you face new challenges Access To People Who Code Better Than YouYou ll get stuck all the time when you are learning to code I still get stuck at work and need to ask my senior for help even my seniors get stuck and need to ask for help It s all part of the game Previously when I was learning on my own I would post in forums for help When I did this I might get an answer I might not But even when I got an answer it sometimes would unstick that problem only for me to find another problem straight away This often led to frustration which would lead to me putting the keyboard away A bootcamp gives you near instant access to someone more experienced than yourself who can help you get unstuck The same is not often true for other forms of learning I can t tell you how beneficial it is to actually see someone debug your code Watching the process someone goes through and learning to imitate that skill is immensely valuable I d read about how to debug and solve problems but it never really hit home until I saw someone do it Maybe you can learn that async or by yourself but it s nice to be able to do it super quickly to save that time for learning Make Friends To Share the JourneyThe best part of my bootcamp was the people I met and struggled with every day on our way to changing our lives It is actually the biggest reason I would recommend you do a bootcamp if you want to learn to code You can learn to code for free by yourself or by being part of communities But I d tried that and it is just not the same You will be on different schedules and different stages of your journey In a bootcamp you re all essentially at the same point learning the same stuff and solving the same challenges at the same time I can t tell you how good it feels to turn to your classmate and ask them how they are going only to hear that they are struggling with the exact same thing you re struggling with Not just so I can feel better about myself but so you can team up and figure out how to solve it together During the bootcamp you re like this little army fighting against the tide of information coming your way You build super strong connections from showing up and fighting side by side every day Post bootcamp the battle isn t over and while you all compete for jobs There is a lot of camaraderie helping each other through the process Once you ve landed that first job you already have a network of developers that are not just within your own company This means down the track if you want to move jobs or lose your job you have access to people who know that you fought beside them in the bootcamp and that you could do it again in their organization I tried the learn at home community taught path and I just couldn t do it A big part looking back is that I didn t have people I could lean on who could understand what I was going through and I didn t have any friends who were developers who could help me learn when I got stuck The friendships I made are for life and I look back fondly on those amazing relationships I built That is the best part of a bootcamp Should You do A Bootcamp in Now with all of that information out of the way it is time for my recommendation as to whether you should do a bootcamp in The answer is it depends I know you re saying WTF Just tell me I need someone to make the decision for me But it really does just depend on you the individual Are you the type of person who can dedicate hours of your personal time to learning to code and you have the discipline to stick to it and no potential hurdles Then you can probably get a job without attending a bootcamp However if you re like me and had a highly demanding job and can t commit to learning with good repetition each week then you might want to consider a bootcamp If you can afford it and actually like coding Just make sure you do your research and if I can recommend one thing in particular it is that you speak to past alumni of your bootcamp It made my decision a lot easier by speaking to real people and getting their private opinions Personally if you can afford it know you like coding and can see yourself doing it for a long time then I d go for it I constantly think back fondly on my time in my bootcamp I ve made amazing friends for life who I still keep in regular contact with even though I ve moved cities The bootcamp was such an intense experience and going through that struggle with others really helps you become quite connected That human connection was enough to justify the expense to me as those experiences were priceless If you made it all the way to the end Thank you so much receive some hot takes by following me on Twitter	2022-02-01 09:36:31
海外TECH	DEV Community	TwNFT - Mint your tweets as NFTs easily and for free	https://dev.to/anishde12020/twnft-mint-your-tweets-as-nfts-easily-and-for-free-2c45	TwNFT Mint your tweets as NFTs easily and for free What is TwNFT TwNFT is a simple web application that allows you to mint your tweets as NFTs for free It is my submission for the Thirdweb x Hashnode Hackathon Live Demo GitHub Repository What is Thirdweb Getting started with web can be difficult even though it is the hype nowadays We need to write something called a smart contract which is required to perform actions on the blockchain To write smart contracts on the Ethereum blockchain we need to learn a new programming language called Solidity Thirdweb provides us with smart contracts which have been written by professionals in the field They also provide us SDKs which makes using these easy This allows people with basic programming knowledge to make web applications with ease Thirdweb also takes care of deploying these smart contracts to the blockchain Let us now go back to TwNFT Where did the idea come from This hackathon was announced back on the th of January but I didn t get a solid idea until the th of January So where did it come from I came across an application called GitNFT from one of Chris Bongers s articles GitNFT lets you mint git commits as NFTs and that is when I thought How about minting tweets as NFTs I did some research and didn t find any application that did this so it was a golden opportunity for me The tech stackWhat technologies did I use for TwNFT NextJS for the websiteTailwindCSS for stylingFirebase for Twitter authentication and data storageVercel for deploying the frontendExpress for the backend APIHeroku to deploy the backendand of course Thirdweb for web authentication and minting the NFT How does TwNFT work One needs to first sign in with Twitter and then put in the tweet URL for the tweet they want to mint Before minting the image that will be minted can also be customized One needs to assign a name to the NFT and optionally add a description or else the tweet s content will be used Before minting we have checks to ensure that the person minting the NFT owns that tweet this is why they are asked to log in with Twitter and if the tweet has been minted before or not We don t allow minting the same tweet multiple times and this is to ensure that every NFT minted is unique Now let us take a deeper dive into the web part A deeper dive into web authentication with ThirdwebSetting up authentication with Thirdweb is as easy as adding lines of code I am using the rdweb hooks package for this application and it is a breeze The rdweb react package is easier to implement as it also packs in the UI However if you want a custom UI which I wanted the hooks package is a better choice Do note that you need to be using ReactJS to use any of the aforementioned packages Coming to the code firstly you need to add the Thirdweb Provider to the application import ThirdwebWebProvider from rdweb hooks const connectors injected walletconnect const supportedChainIds function MyApp Component pageProps return lt ThirdwebWebProvider connectors connectors supportedChainIds supportedChainIds gt lt Component pageProps gt lt ThirdwebWebProvider gt Then it is as easy of using the useWeb hook provided to us by either packages to retrieve the connectWallet function We have to now just call this function with the wallet type lt button onClick gt connectWallet injected gt Login with Metamask lt button gt Here injected is for the wallet injected in the browser This is Metamask in most cases For a detailed guide on implementing web authentication with Thirdweb check out their official guide A deeper dive into minting the NFT with ThirdwebI am using the Thirdweb Typescript SDK for minting the NFT on the server side Minting should take place on the server side for security reasons Minting with the Thirdweb SDK is extremely easy Let us see how it works First we initialize the SDK with our private key Do keep this secret as anyone who has your private key can gain access to your wallet I am using ethers for initializing a wallet here const SDK new ThirdwebSDK new ethers Wallet process env PRIVATE KEY ethers getDefaultProvider Next we initialize the NFT Module that will let us mint the NFT const nftModule sdk getNFTModule process env NFT MODULE ADDRESS At last we call the mintTo function asynchronously const result await nftModule mintTo payload receiverAddress nftMedatada Here the result gives us the NFT s tokenId The tokenId is a unique identifier for the NFT in that collection Now that is it We have minted an NFT For a more detailed guide you can check out Thirdweb s official guide on minting an NFT What was this NFT Module Thirdweb provides us with many modules and the NFT Collection module is one of them It allows you to mint an NFT in an NFT collection and that is what we just did The official collection for this project can be found on OpenSea here ️Using TwNFTTo get started log in with Twitter and head over to the mint page Next put in the URL to the tweet you want to mint in the textbox on the top and click the arrow You should now see a preview of the NFT something a bit like this Feel free to customize the image by clicking on the buttons on the options bar Next click on the Connect Wallet button and connect your Metamask wallet Walletconnect support is coming soon You should now see a button saying Mint NFT instead of Connect Wallet on the options bar Clicking that should bring up this modal where you can fill out the name of the NFT and optionally add a description After some time you should get the option to go to the tweet page The tweet page will look somewhat like this do give the image some time to load for the first time Notice that it says the NFT is still being minted and it is going to take minutes Check back after minutes and this is what the page should look like The NFT is now under your wallet and you can do anything with it including listing it for sale selling it and even transferring it to another wallet ️SidenoteCurrently TwNFT is running on the Rinkeby Test Network This means all NFTs minted will be on the test network and not on the main network However this is subject to change in the future ConclusionIt has been a great journey over the last days making TwNFT squashing bugs and implementing features Excited to see how it goes Bye and have a nice day Important LinksTwNFTTwNFT GitHub RepositoryTwNFT Backend GitHub RepositoryTwNFT OpenSea
