"Starfighter is a new, weird kind of recruiting company. We detect and market underpriced programming talent. We do that by creating opportunities for programmers to casually and effectively demonstrate aptitude." Having a hard time parsing this. Do you find underpriced talent and help them get paid more?

Yes, that's the thesis. I mean, we're happy to represent anyone capable! But we're particularly interested in the people with no resumes.

Susie works making crud apps for a boring insurance company. She is a brilliant programmer but due to where she lives, personal situations, she hasn't faced a challenge that lets her know the extent of her abilities, etc, she is working below her potential. Susie creates a novel solution to one of Stockfighter's games. Stockfighter uses that solution as evidence to present her to companpanies as a great engineer. She…

Except according to an earlier posting from someone who went thru the process -- they didn't get a direct offer: they still had to go thru technical interviews. I thought a big point of this was that you could skip the BS technical interviews and prove yourself thru this. https://news.ycombinator.com/item?id=11433414 While it's a great service, this takes a lot away for people who are great programmers but might not…

We're just recruiters. We exert pressure where we can and get process breaks from most of our clients, but we're a tiny little company. Everyone gets interviewed.

Nobody wants to eliminate tech job interviews more than I do.

I know this is a low-quality comment, but i just want to congratulate the whole stockfighter team for getting the jailbreak ctf out. it looks like it was a ton of work and looks fantastic. as somebody who was excited about it after trying my hand at microcorruption, i'm super excited to see this finally. hats off!

Thank you!

This is just an early demo version. It's going to get pretty bananas in a few weeks. Noisy testers are very welcome; we're going to start spoiling the "full CTF" levels next week for beta testers.

Hi man, I just interrupted my game of Overwatch because a colleague pointed me to this comment. My C compiler in Haskell is located here: https://github.com/tinco/nanc it's not fully functional yet, but will be soon ;) Also, just got owned by a team with 3 tracers :( edit: Just read what this thread is about.

Kudos on your cool side project, and triple Tracers sounds like the pinnacle of frustration :P (is this…

Could very well be then! They played 3 tracers a winston and a Mei. (Winston had a play of the game smashing four of us in Mei's ulti :\)

I'm 29, experience the same with SC2, it's just not fun if all you can do is to learn the meta and polish your mechanics.

Whatever you build, make sure it's test driven! Nothing beats sitting down to work on your project and the only thing you need to do is to run the test suite to remember what you should work on next. It also helps you chop your project up in fun achievable sized bits. I make it a point ending every session with 1 red test.

I haven't tried this, but https://github.com/ketchupsalt/debugger might be of interest to you. More generally, it's not actually sandboxed inside a web browser, you can interact with system through REST-ish API as well. see https://starfighter.readme.io/docs/retrieve-device-status for some documentation on that.

This line seems like a bug to me (assigning the int 16 to a variable that should be of an enumerated type {I8, I16, I32, S, R}, though I don't know if Go has those):

Snif. My feels. Right in the feels! Try as hard as you like though, you cannot make comments like these unproductive!

* You cannot "explore the filesystem". The "files" are really just bookmarks in case you want to switch between different C-like programs to deal with a level. I hate the UI more than you do, but suggestions very welcome.

* You mean "compile" as in, the debugger command? What would you like it to print? Before we split the source editor off into its own page (it used to live in a tab, and it just didn't work), the CLI was an important way to interact with the compiler. Now the command is vestigial. I suppose I could just make it print out the bytecode instructions from the compiler.

* What does "inspect the compiler" mean?

* How can I surface the documentation that explains the relationship between the compiler and the system so that it is more apparent that it exists? It's clear you didn't see it.

* Hate the web interface? You're in luck! https://starfighter.readme.io/ --- skip to "Microcontroller API reference".

* I have a hit list of improvements to the command line, but if you have more suggestions, I'd be happy for them.

* The "latency" you're seeing when you single-step programs is... the network? The clientside UI code?

Just a little, is the answer to the last question.

Which "load" command? What's the feedback you're looking for?

Did you write a C program, click the compile button, and now want to run it? Just type "run".

There's an in-game reason why we break out the flash/load/exec commands the way we do, but "run" does all the fiddly steps.

Speaking only for myself, I have near-constant coder's guilt - a term I just made up to describe the nagging voice in my head that keeps telling me I should be coding more in my free time.

Do you code for your day job, though? Your profile suggests you may be a technical manager. I'm guessing you don't code for 8-10 hours a day, then come home and code for 1-2 more hours[0]? That's the argument the parent is making. I know that I personally am only good for 4-6 hours of productive coding. Any more than that and I write bugs, not code.

[0]: If I'm wrong and you're doing 10-12 hours of productive code a day, then good god man, what's your secret?!?
