Make an image manipulation program like paint, or make a simple game like pong. Worked with public APIs before? Try pulling stock information or google maps data. Etc.

I'm looking for C# practice, um... not sure what else to say. What are you trying to do? Going through your post history in this thread, you sound like someone that doesn't give a poo poo about coding, but wants to make money coding. You're not anywhere near being an expert just from taking some online courses and reading some books, I wouldn't even classify that as "competent" by the following model: https://en.wikipedia.org/wiki/Dreyfus_model_of_skill_acquisition This isn't to poo poo on you and the effort you put in, but it's a wake up call. If you want to make money, look at the companies in your local area and what they're hiring for. Look on Linked In, go to job fairs, go to conventions and see what is in demand and how much money you can make. I can tell you in my neck of the woods Kotlin and C# do very well - Android developers are hugely in demand, and even bad ones are treated like royalty. You can totally slot in as a 9-5 career developer with either. Some places just want cogs in a machine that will do the work. If you want to go beyond that, it's a different conversation. You probably want to work someplace that has a product, or a website that is integral to selling that product. If it's a larger, enterprisey company, that means some flavor of Java or C# probably. If no companies in your area use C#, that's not a very good language to start with, so just keep that in mind. Smaller companies tend to lean towards Python or Node these days. Honestly, I'd pick Kotlin as a generic response to anyone looking to get into programming. It's probably the best flavor of Java, it's got great momentum, you can do enterprisey Java API/apps development with it, or you can do Android development with it - and both of those are in demand. You can also easily switch to Groovy or vanilla Java if you know Kotlin. I didn't get a job coding until I had built something, and I don't think that was just coincidence. I like weather for example - so I built an app that grabbed and parsed a bunch of weather data and threw it into a database, then I built a REST API that exposed it, then I built a phone app and a website that consumed that API. Pick something that you can dogfood because its so much more interesting to work on. Also, if you've settled on C# as being what you want to do for example, keep up to date on a few C# related blogs, read Hacker News, and follow the current and future release notes for the language and the .NET framework so you can intelligently talk about features. luchadornado fucked around with this message at 03:38 on Jun 29, 2018 |

Speaking of asking repetating questions with a time lag, does anyone know how to configure a create-react-app dev server with a custom MIME type? It's something that seems like it would/should be straightforward, but it's perhaps the most elusive programming question I've had; asked multiple places on the internet, and have had 0 suggestions, and 0 relevant search results... this implies that this is a deceptively devilish task. I need this to use WASM:quote:Note: To run with instantiateStreaming and compileStreaming, you need your webserver to serve .wasm file with application/wasm MIME type. The https crate can be used to serve files from localhost, and includes the application/wasm MIME type out of the box. Any thoughts on why this is so elusive?

We’ve got an epic to work on at work that is rapidly getting more complicated and I’m a little overwhelmed. We have a project that is split into a Rails UI codebase and a Rails API codebase. The UI builds some stuff using its Postgres models and puts into a Mongo database, which the API then consumes and exposes. We want to stop using Mongo, but from my digging into the codebase, getting rid of our dependency on Mongo means that we will have to share a LOT of models and functionality between the API and the UI. We’ll have to break out those Postgres models into a gem or something, and share them between each codebase. And this is like, the backbone of the UI and API project, to the point where it’d just make more sense if they were the same codebase. I’m not sure this will be something we can do in two months. Does anybody have advice on how to tackle a project like this? I’m really not sure where to even start making changes, or what would even be my best option.

I’m digging in and it’s so much worse than that. I genuinely think trying to share models is a bad idea, and we should instead just put up some API endpoints on the UI side to expose the data the API needs. Am I just being lazy or giving up?

C# is probably my favorite language, but most places pick either .NET or Java for enterprise type development. If there aren't a lot of places that use C# around you, there won't be as many opportunities to get work, etc. One of the two is bound to have opportunities in your area, just figure out which one (or both in some markets). Java is more ubiquitous. Kotlin is made by JetBrains, makers of the only good Java IDE IntelliJ IDEA, and other cool things like ReSharper and PyCharm. They understand how languages work, and got annoyed building their IDEs in Java/Scala/Groovy (all Java Virtual Machine languages) due to various problems with each of the languages. So they made their own language that also runs on the JVM, but is heavily influenced by parts of Scala, parts of C#, etc. It's pretty good. If you know Kotlin, it isn't hard to switch to Java, Groovy, or even C# for that matter. Definitely focus on getting one language down first. I know some devs with good careers focusing on a single language, but I would argue polyglot developers are more useful and usually have better careers.

Don't learn Kotlin for your first language. It only even exists because android doesn't support recent java language features and the number of people using it is fairly small. It's sort of hot right now but there's a very good chance it will become this embarrassing thing that nobody wants to admit to have ever liked in a few years like Groovy.

Doesn't seem like a good idea to learn two languages at once with these textbooks clocking in at 800+ pages... Thanks. You haven't said what you want to do. "Games, websites and apps" is hella broad and even just picking one of those is gonna give you a ton of routes to go down, with different tools to learn depending on what you're aiming for If you're just looking for A Job and you're happy with any of those areas you mentioned, and not particularly bothered which, then do what Hellcity said - look at what's in demand, pick one, and go do some tutorials until you know enough to a make a little project of your own. It's a learning process and it's something to show people But if you want to do something in particular, you'll need to look at the technologies that get used in that area, and specialise a bit. If you want to do iOS apps, you'll need to learn Objective-C or Swift. If you want to do Android, you'll need Java (and Kotlin is becoming a new standard too). C# is very similar to Java in a lot of ways, but you won't actually use it in Android dev. Websites (frontend anyway) tends to mean Javascript and learning some frameworks. Games tend to be C++ and sometimes C# - and as far as I'm aware, it's a bit harder to break into that field without creating something to show you know what you're doing. I'm generalising but hopefully you get me

People don't just use Kotlin because of Android. People use it because it's a strict improvement over Java without the complexity drawbacks of Scala. Unlike Groovy, Kotlin may not be Super Popular in five years but nobody is gong to be embarrassed for using it. It's a sane modern language which is reasonably representative of the mid-to-leading edge of popular software; the lessons it encourages and enforces are good ones to apply to other languages. But TBH anyone learning to program just to get a job is going to be basically useless at their first job until the company spends six months getting them up to speed anyway so it's mostly an academic argument. And, FWIW, mobile is a bad place to be. Write things people actually want. They don't want 95% (or more) of apps and the companies with apps people want are generally staffed by more senior people. Junior mobile development is body-shop work. tracecomplete fucked around with this message at 16:54 on Jun 30, 2018 |

This is a much better way of saying what I was going to. I don't think learning any of C#, Java, Kotlin, Python, or Node would be an egregious mistake but there are pros and cons to each. I've seen a lot of new devs flourish with Kotlin and Python recently, although Python work is hard to come by (in my area). We have a really strong Kotlin community here, so I might be more accepting of it.

I would teach someone Go or Python for their first language I think. Relatively clean syntax and decent demand. If you just want to Get A Job dehumanize yourself and face to JavaScript, it's the one language that's absolutely unavoidable, but I kind of hate it. Java and C#/.net are everywhere but it's also much more heavyweight and so harder to practice basic programming with.

It sounded to me like someone wanting to get some more experience with some coding, not design and manage a whole project, where they'd have to make architectural decisions as well as potentially having to evaluate others' submissions. Working on your own codebase is a lot easier than integrating into somebody else's. Hooking into somebody else's requires a lot of research and proficiency in figuring out where things are, general language conventions, stuff like that. It also requires much more formality with code cleanliness and documentation clarity, which can be a double edged sword (it's certainly not wholly a bad thing). Your own project may end up an unidiomatic nightmare, but as long as it compiles and does what's advertised it works and gets you some experience, at the risk of falling into bad habits. I'd only recommend starting with open source contributions if you get pointed to a project that has mentorship or at least nice people who will calmly explain where you should put code or how to refactor/lint/whatever your contributions. Now, your solo project more likely than not isn't going to get any users, especially if you made it just to write code and not to solve a problem you actually had (we don't need Basic Ray Tracing Library 299,754,210), but I think there's less pressure when you're the ruler of your own little code kingdom. KernelSlanders is right when they say it's difficult to make meaningful contributions if you haven't used the library and found its flaws or limitations yourself. You can ameliorate this if you're experienced enough. Once you have enough experience you can kiiind of jump into a codebase with nothing but an issue tracker and start trying to integrate things, but jumping into codebases just to contribute unless you have very specific goals ("I plan to use this eventually and want to become more familiar now", "I want to learn more about <X> and this is a library and contribution about <X>", etc) can be dicey at the best of times. If you're a newbie and write an open source library that somehow explodes in popularity, then yeah, suddenly you've gotten yourself in hot water that's way worse than merely diving into a big project. But that's extremely unlikely to actually happen. I do in general find "just go code" advice pretty bad, though. A lot of people don't have passion projects they just want to code, and often at a novice level you don't really have a sense of what's feasible or even available for you to do. Even as a more experiences programmer learning a new language I find it easier to learn by coding a task I already have in a new language than inventing a task "just to code" and learn it.

If you pick up a larger, active open source project, chance is it also has a community of people who can help you get the build/test set up, and give you feedback on your changes both for logic and code quality. There will often be people with deep understanding of the problem domain, so they can give more qualified help. If you start your own project, anyone you ask for help will need to learn a lot more about your structure, goals, and problem domain, and the problems might not even be any simpler.

Goat another one, but at least I recognize the language this time. It's a VB script that is meant to scrape the data from incoming emails, put the pieces into string variables and then feed those strings into a pick database. This is working fairly well, but I'm running into an issue with separating a combined City/State value. The original email message will come through to us and look like the following: From: Jimmy Vivino Email: jgvivino@gmail.com Phone: 666-524-8751 Location: San Diego, CA Inventory Location: Newport Beach, CA Stock #: 6660434 The Process reads down the email, line by line, does a CASE lookup against the field name (sFirstArgument) to the left of the ":" and returns the value (sSecondArgument) past that point. it then takes that string value and adds it to the corresponding variable so the name, or From in this case, goes into sName, email to sEmail and so on. And by and large, this has been working for most of our email submissions. But when we get down to a city and state on the same line, that's where I'm running into problems. Most of our other emails come in formatted with those items on separate lines and those process fine. This was thought of by my predecessor, who built this whole system, but it seems a bit broken here. Case Statement below with comments: code:So I have some idea as to what the problem is, but I'm unclear as to how to fix it. I know that all the messages I'm tweaking this for will have "Location" as the field name, and all the results will be in City, State format. Can I just split that string on the comma and feed sPiece(0) into sCity and sPiece(1) into sState? It kind of dawned on me as I'm typing, but I think that should work. Thoughts?

I don't know the syntax but it looks like that's going
So something like San Diego, CA will be real broken because first it splits on spaces, "San"; "Diego,"; "CA", then it sees there's a comma in there somewhere and throws out everything but "San", and expects all the data to be in there. It's expecting the whole thing to be formatted like City,State,Country with no spaces anywhere. I'm assuming the initial split on spaces is meant to catch multi-line cases or something? If you know all your stuff is gonna be City, State then yeah just split on the commas (and look for some kind of trim command to remove the extra whitespace, or just split on ", " or something). But if some of it is on separate lines, you'll need to spot that and handle it differently. If those are the only two situations, it's probably fine to handle them separately instead of having one parsing thing that does everything. Also, I'm guessing the multiline stuff doesn't work for something like San Diego CA either, since it's splitting on spaces (probably get Diego as the state) So yeah it would be something like
