Anyway it says that I need to know C++ so I'm going to pre-empt the coding month by learning some basic C++ in February by following a course at codecademy. How's the C++ thing going? I restarted learning C++ (I tried some back in 2017, didn't get too far) week ago and I'm about to get into memory management and advanced classes stuff. It's getting complicated now. Hopefully I'll manage to not to lose motivation like it happens with most things I start.

Modern C++ uses a lot less pointers in favor of references and move semantics. You can't get away with knowing nothing, but you can write a lot of code without using pointers.

It's good to see goons learning to code. I mainly use TypeScript for my job and while I really like it for frontend development it is hot trash for backend code (I didn't choose Node someone else did). I've used a bunch of different frontend frameworks and Angular is by far my favorite, although I haven't touched ASP.NET or React in a few years so maybe they have improved. For anyone interested in learning how to build websites I'd suggest just learning basic HTML, CSS, and javascript first before diving into a framework. If you already know the basics I can't recommend Angular enough. If you already know Angular spend some time learning how to work with Observables and Subjects, they are really great and once I had a good grasp on them I was able to completely remove Redux from the projects I'm working on.

If I may recommend yet another language, R is neat. If you use Rstudio, it makes it really easy to write Rmarkdown, which lets you make workbooks that you can use to show off your results to normal people. I find the ggplot2 library to be miles better than fighting with excel plots, especially if you want something more complex, or if you want to do some summaries or statistics first. R is slightly weird, but I don't think it's especially difficult to pick up - and "I have some tables of numbers I need to analyse or present" is a fairly common problem. It's also easy to get started with, since you get both a light IDE and an interactive shell to poke around in. I learned on my job (and it was not my first language), so I don't have any first hand experience with the resources that are available - but I can look, if anyone are interested, and I'm happy to answer questions.

The other two OO systems (ok, point taken) are just kind of there. Beyond that, though? The basic syntax is boringly standard, just yet another curly bracket language.The underlying model is a surprisingly complete and neat functional language, though. I suggest a dive into Hadley's Advanced R - it's fascinating. (I haven't looked at the 2nd edition yet). I fully understand it if you think the alternate evaluation system should be fired into the sun ... but I genuinely like having an entirely standardized, user-accessible, way to make little domain-specific languages, like the formula syntax. Compare and contrast to Go, where parts of the language are just Blessed by Google to do things you can't replicate in pure Go.

I got a c++ question: I'm doing a lesson at codecademy where I need to add up entries of a vector and output them to a new variable, no problem. My solution is, very loosely: int start_value = 0; for (iterate stuff) { start_value += vector<i>; } This works, but the solution suggested by codecademy is: int start_value = 0; for (iterate stuff) { start_value = start_value + vector<i>; } I have bolded where things are different They both do the same thing, and seem to work just fine, but is there a reason for why codecademy's solution is preferred? Here I'm thinking if one method requires less cpu cycles or RAM or whatever?

Dumb Sex-Parrot posted:I have bolded where things are different They are almost certainly going to compile down to the same machine instructions, though your solution has the potential to be more efficient, since operator+= doesn't create a temporary value like operator+ does. But that only matters for complicated types with overloaded operators, for ints it's whatever.

You can come up with correct solutions to the problem that look a lot more different to codeacademy's solution than yours does!* and like Mooey Cow said - they probably all end up as the exact same machine code after compilation, because C++ compilers are fairly sophisticated at recognising what you are doing (if you're doing something commonplace) and optimising it. * as an example, you could use std::accumulate() and make it into a one-liner.

EX: Here’s bubble sort or here’s how to write a client server in that language. O’Reilys progression from beginner to knowledgeable in language X is usually learning X, X, X cookbook, X specialized stuff... They’re good books, but I don’t think they fall in the tutorial category if you’re looking for tutorials.

Frontend? Backend? Full-Stack? A full-stack kind of idea would be to put a frontend on a public api and do something silly with it. https://pokeapi.co/ https://docs.coinapi.io/ https://thecatapi.com/ Bonus if you can work some cloud services into the hosting. EDIT: When I say "something silly" I realize that may not be super helpful. So what I mean is something involving persistent users or state (a database or data-store) as well as doing something that isn't just calling the api and dumping json to the screen. Ideas for the state include allowing users to register and mark "favorites". Generating reports that are saved with a unique hash for bookmarking/future reference.

BornAPoorBlkChild posted:Full Stack for sure. So basically just futz around with Public API Keys? From a priority perspective, the things our Full-Stack people deal with on a day-to-day basis:
So make a "Webapp" that has state (something saved to database) utilizes external APIs (make http requests to other sites you did not design) and looks like someone thought a little bit about how the frontend works (Javascript Single Page app + CSS) The "canonical" example project is a task list app, but I like the idea of integrating with services beyond your control to show you know how HTML REST/GraphQL apis work from a consumer side. Other than that, I'm not involved with the resume pipeline for Junior Software Devs at my company, so I'm not 100% certain how to stand out other than just apply to anything that looks interesting as much as you can. Be honest, and don't be afraid to shoot a little into reqs that include keywords you're not experienced with. If you see a keyword enough... bolt it onto your portfolio project so you can at least answer screener questions about it. When we're interviewing juniors, we're mainly making sure that you are familiar with functions, unit testing, control statements (loops/if/else), regex and reading code. We're also evaluating how you explain things and how you react to questions that are beyond your comfort zone.

Spring and J2EE have free versions but they're a lot to take in. If you're looking to understand the basic concepts of Dependency Injection like those two frameworks have, it's also worth looking at Guice (my personal favorite) and Dagger (extra simple) to see how it works. They all have an issue where it feels totally magical until you understand what's going on, but if there's a point where it becomes less magical it's Spring > J2EE > Guice > Dagger.
