This is the PA programming thread, home to programmers everywhere. Here we talk about cats, ponies, synergised high-efficiency software cloud platforms, and occasionally programming. Apparently the old OP is, well, old, so we've constructed a revolutionary new cost-effective commercial-grade solution for all your enterprise needs.

PADev.net is a project started up by this thread to support PA developers. A discussion about shared hosting turns into an idea to have hosting and a community to support those working on hobby programs and web services and what not.
Some things require a dedicated VPS but the bar of entry isn't that low. The cost is not extravagant but the know-how required to manage one is daunting for many. PAdev.net provides a share of hosting and support, a $5 monthly fee nets you a shell account on the hub server and the expertise of your peers.
Community members looking to help out can request an account for the website, where all members can create and maintain guides and share project updates. There is no cost to have a community account, just contact an administrator. Also available are you@padev.net email accounts or forwarders.
Current administrators: @Infidel
Languages
- Python - One of the most popular scripting languages around, Python is the go-to language for...just about everything, actually. Its high scalability and widespread support through third-party libraries make it useful for many applications, from simple five-minute jobs to complex Web servers. Python can also be embedded or bound into lower-level languages such as C, letting you write performance-critical code as well as providing access to libraries written for those languages.
- Ruby - Another popular scripting language, Ruby is best known as the basis for Ruby on Rails, a framework for Web development that competes with its Python equivalent, Django. While not quite as famous as the juggernaut that is Python, Ruby is nonetheless prolific - modern versions of RPG Maker use it as their scripting language, for instance. And, of course, it can be embedded into other applications, much like Python.
- Lua - Yet another scripting language. Lua is built on two principles: simplicity and minimalism. Designed with embedding in mind, Lua's overhead is tiny (it can be counted in hundreds of kilobytes at most) and the language itself only provides a handful of constructs...until you master the black arts of tables and metatables. Those who have done so claim to have seen the face of God; these claims are as yet unsubstantiated. What we do know, however is that in recent years Lua has garnered much attention thanks to LuaJIT, a project that provides not only a just-in-time compiler for Lua (granting a massive speed boost - almost C-like performance, in fact), but also an FFI (foreign function interface) library, allowing Lua scripts to directly call C functions without the hassle of writing boilerplate C bindings.
- C and C++ The Ones Who Came Before. C and C++ are old, clunky, archaic...and the most popular languages in existence. C was conceived in an era when memory was limited and programs were generally written in non-portable assembly languages. The underlying concept (which persists to this day) was that a compiler would take C code, turn it into assembly, and then turn that into an executable or library. Thus, programmers now only had to port most of the codebase instead of all of it! (the situation has improved considerably since then, of course - these days, only the really low-level stuff has a tough time being cross-platform). C++ came some time later, and shook things up significantly with the concepts of classes and generics. Modern C++ also includes the Standard Template Library, or STL, which provides all sorts of useful functionality to make life almost painless. These days most people will learn something simpler like Python before these guys, but make no mistake - everything from your operating system to your favourite video games to your microwave can trace its roots back to one of the two.
- C# - The poster boy for Microsoft's .NET Framework, C# is a JIT-compiled language modelled after C++, but without any of the associated pain. Though initially developed as a robust alternative for Windows development, Microsoft makes the specifications available at no cost, which has led to other implementations popping up - the most well-known being the cross-platform Mono. The main draw of C# is its ease of use: with a ridiculous number of APIs available by default and the ability to call into native code, you'll have a tough time finding something higher-level that you can't do in C#. The fact that Visual Studio, one of the best IDEs around, also supports C#, is just icing on the cake.
- Android - Directly responsible for bringing this OP into the 21st century, Android is a pseudo-operating system framework which runs on top of Linux. Android is primarily written in Java, though it also combines elements of C, C++ and sometimes even Python, and is designed for mobile devices. The Android application framework represents an almost entirely event-driven paradigm written primarily in Java which heavily utilises usage of background services, model-view-controller, and sub-classing as a method of changing behaviour of standard pieces. Also, it runs on your phone!

Saturday:
Me: Man, this is a really nice day and I'm looking forward to relaxing after these chores.
Brain: You know you can turn loopback on, right?
Me: What? What is the context of this thought?
Brain: You know, work. At work, you're trying to calibrate without a reference. But if you turn loopback on, you can provide your own guaranteed reference.
Me: IT'S THE WEEKEND GODDAMN IT but yeah you're right.
Silly brain.
So here I am Monday morning, nutting through the details.
If I do this right, this (small, but critical) portion of the project will be self calibrating and relatively robust to hardware changes....
Is nice an all, but the slowness and overall badness of the IDE (Is an error that your code isn't translated on ALL languages by default when you create the .apk? Really?)makes the experience kind of annoying.
Android Development: Kind of Annoying. A more truthful slogan.
Basic Java is smooth and polished by comparison.
Insights when learning clojure and being involved with the language in general feel very satisfying. Immutable data structures and "values" certainly is one of those. Async, lazy sequence functions & eager parallel reducers, recently transducers etc. Transit is nice, even if doomed. I find the language's philosophy on how to do programming and to approach problem resolution very attractive. I'm hoping we'll be delivering our first clojure project by the end of the year!
In the video with Beckeman I posted above(unless I am remembering the wrong video.....), they briefly discuss performance and algorithmic guarantees they needed to satisfy for the immutable data structures, could be interesting for you if you haven't seen it.
Unity feels more complete, but god damned does it feel like it's more an art asset engine than anything. It feels like programming is just tacked on.
a big problem this year for some of the poorly funded teams is car turbulence is causing the systems to crash and reboot, effectively leaving the car dead while it restarts
i am wandering aloud what kind of turbulence could have an impact on a computer with no mechanical harddrive that would cause the system to shut down and restart
as a humorous bonus, when the system reboots, they get a branded BIOS screen that they have to wait on until the system finishes loading. no word on if there's a key to hide it so they can see their memcheck and S.M.A.R.T statuses
Maybe issues with the connection between the power and the board, or maybe the board is actually twisting causing shorts. But I am not a hardware guy.
Are you sure about that? I suppose it's also possible something is becoming unseated/disconnected.
Somehow two days has cost the company $18.30. I go into the cost explorer and there's just words and acroynms and it's almost like the phase of the moon has some effect.
This is before I've started spinning up 10 EMR nodes, so I'm looking forwards to seeing that bill once I start trying to crunch 26 million records.
Probably that.
If you haven't got your interference suppression sorted correctly, you're up the creek.
It's surprisingly tough to get interference sorted out - it comes in from every possible nook and cranny (or hell, even conducted through power cables).
And that's wangernumb!
But, it get me a degree in the end... How is this useful? this better be useful.
Edit:
for those who use java :rotate: what IDE do you use? I was pointed to jgrasp.
edit 2:
I have visual studio, can I just use that?
It works just fine for assignments and school projects, and is likely what the majority will be using so you can get some help / not run into unexpected issues so much.
To be fair, the materials from Building Java Programs is fairly complete insofar as lecture notes and assignments go. But yea, ideally as an instructor you use other material as a basis and make it relevant in-context for your class. That being said, many instructors don't, especially when they are removed from the material.
Also, even though you have some programming experience, I highly recommend that you avoid an industrial-strength IDE like Eclipse or Netbeans. Use a simpler IDE like jgrasp or drjava and spend your effort on soaking in the material rather than fighting your editor. Alternatively, if you feel up to the challenge, rather than use a teaching IDE, use the class as an opportunity to teach yourself basic unix command line development skills. Such skills are essential as you move through a computer science curriculum.
taking some time off from C to work on my tooling systems. I'm going to build my game data management tool in a local rails instance running off of SQLite. Then I'll write a bash script to curl all of the JSON out of Rails and save it to the client directory
can't think of a faster way to have a GUI interface for building out items/monster data
I used NetBeans to learn both Java and OOP when I was on that part of my career, is not hard to use. It comes whole with the Java Development's Kit since years ago, so you just install it, decide where you want your files to go, and then is File -> New Project -> Java Application, write the name and off you go.
I still use it.
I am feeling almost irrationally opposed to the idea of encoding any metadata in variable names. I'm okay with using a single char or even capitalization (see: golang) to differentiate between public and private facing variables, or to get around an IDE or language deficiency. Hungarian notation would be the worst version of this, but in this instance it was using prefixed m_ for class members and s_ for static fields in java. It just fells like this unnamed person or persons are going out of the way to make java even more verbose than it already is. Eclipse, IntelliJ, and vim will all display those differently inline anyway. And statics that aren't CONSTANTS are rare anyway. Or at least they should be.
</rant>
Am I wrong?
I've heard good arguments for putting useful information in variable names, like having raw_ before strings that come from user input, and safe_ for ones that have gone through validation.
But then I think that's the sort of thing we make classes for. Don't have String safe_foo and String raw_bar, have SafeString foo and RawString bar.
NetBeans is a perfectly fine IDE. But at best, it's complete overkill for an introductory programming course and at worst, hides some of the important details of how compilation works from the student. I would go so far to say that there is absolutely no gain with using Eclipse/NetBeans over a simpler IDE like jGrasp/DrJava or even a text editor with appropriate syntax highlighting in a CS1 course especially one based on the book @DyasAlure is using.
Nope. You just need to be using the right language, is all!
let gen_eexp_rel_app (s:Sig.t) ((xrel, trel):id * typ) (g:Ctx.t) (t:typ) (met:metric) : exp Rope.t = (* ... *)At least, as a prefix to the variable.
Using them in the middle is chumps.
theBest is better than the_best
I use upper camelcase for Public variables/functions, and lower camelcase for private.
Dashes are sort of fun as a whitespace delimiter (e.g., find-system-path). A smaller part of me wishes for more languages to do that. A larger part of me wishes that coding conventions were consistent between languages so I didn't have to switch back and forth.
Our Team Lead was going to try and get us a few hours to play around with HTML5 so we can build some decent mobile apps and start on it. When he talked to the department manager about it he came back pretty much saying "Yeah they said they weren't interested, I guess it's time to abandon ship".
That arugment transfers over to any naming convention. e.g. namesWithCamelCase, naWiCaCase, camelCaseNames, namesCamelCased
Someone's getting real close to a stabbing.
___ and ____ for lyfe.
In some places this is reference as stk or STK, in other stock and STOCK. In the core as core gets library, that has been around for about a decade.
