Also sticking equations in images is poo poo for accessibility, but so was almost everything in 03. I think some form of https://en.wikipedia.org/wiki/MathML was (poorly) supported by a few vendors back then?

Well I was going to refrain from pointing out that the first version was in 1998 I think, and somebody probably did make a pdf of this by now, I just don't know where it is. I mean, it serves its purpose  You can still understand it on a computer almost 20 years later.

I'm not even close to being a Windows programmer, but I've got an idea for a little utility that I want to make with Electron. The one problem I see with this is that I want to be able to do some TextExpander-esque things and I'm not sure how to go about that. I guess I'll need to write something in C# or something because I doubt Electron has any hooks or whatever that are low-level-enough to monitor keyboard activity system-wide like that? Anyone have any low-effort suggestions? Failing low-effort, just the lowest-effort... I mean, I could just use TextExpander or something like that but I want to redistribute this utility.

Does anyone know if there is some sort of service/api that would allow my company to track issues relating to health/status of IoT devices? I already wrote a bunch of health checks that get executed by AWS IoT, right now they just notify slack. Unfortunately that isn't good enough and people want/need to be able to see a history of the various issues that occurred on the device. This project has been stuck in development hell for loving ever, so it has been dumped on me. What has been done is a  cthulu of spaghetti that tries to twist Jira into an IoT issue tracker.

If so, you could use that and consume those logs (I can't remember how long CloudTrail persists logs but probably not long enough for what you want) and store them somewhere. If not, what about SNS or SQS?

With C# (or C whatever) on Windows you can do a few things. You can hook it using SetWindowsHookEx but I'm pretty sure that there are better ways now. I've used the raw input api and it works as advertised. Another option would be to use DirectX, but I couldn't tell you how.

This is probably a dumb question, but it's for a personal project where I'm trying to learn stuff: The little project I'm working on has to do with college programs. I'm interested in using some data about each school (current tuition rates, list of majors, etc). It's all available on their websites, obviously, but I'm looking for some way to hook into that data and have it all available to use. I did find that there is official federal documentation with lists of all accredited schools in the US, which is really cool, but it doesn't have the type of detailed informative I'm looking for. Any tips on where to start with something like that? It's a c# application if that matters.

What you probably want is called "scraping". For C# you might try using some HTTP download class to get the web page in raw data format, then feed it to HtmlAgilityPack to turn it into HTML, then find the particular data you need by rummaging around in the document. The rummaging part can be easier if you open the web page in your browser and right click the element and choose the "inspect" menu item, then see if you can come up with a CSS selector that matches the element you want. Hopefully that gives you some terms to search for and places to start.

Scraping is the alternative if the data service you're trying to rummage through doesn't provide a public API, service or what have you for developers to connect to. Guessing the pages you're talking about don't have a public interface for that, so yeah, scraper

Well, here's a data source: http://nces.ed.gov/ipeds/datacenter/Default.aspx Automating retrieval of this data seems like a huge pain in the rear end, but you could download a huge ream of it on your own in CSV format from multiple institutions. edit: Actually: https://github.com/DataUSA/datausa-api I didn't look too closely at it but looks like someone did the work.

If you're totally blind, I'd guess it'd be almost worthless just considering he's representing powers as a character on the line above offset by a space which is  as gently caress. Also there's no structure to speak of for a screen reader to follow.For a visually impaired user who can see the well enough to get a sense of the structure but needs a screen reader to figure out what characters are on display, I think it'd be more useful than an image without an alt attribute. Disclaimer: this is guesswork based on usability testing I, a person with better than average eyesight for my age, have done occasionally because it's part of my job and it's possible that actual blind people are way better at coping with this poo poo. It's worth pointing out that when you look up anything math-related on Wikipedia that there's usually a formal description of the equation and an image (possibly generated from MathML?) because IIRC that's what their guideline says to do to make the articles accessible.

Anyone have any low-effort suggestions? Failing low-effort, just the lowest-effort... Having not heard of TextExpander and just looking it up, I'll second Munkeymon and suggest that you look into autohotkey for low pain windows implementation of this sort of keyboard hijacking. The language itself is painful to use, but simple stuff is simple enough, and the compilation / execution is straightforward. If you decide to use it, there's a pretty good autohotkey package for SublimeText2 (syntax, compile, run, etc). I imagine that you'd end up generating AHK code with your electron app? What are you planning to use on the linux / osx side? I've had a repetative-stress-injury-prevention keyboard-remapping project in mind for a while, but my limited research didn't turn up much, maybe because I don't know what any linux words mean. e: someone did start into a C# implementation of AHK, called IronAHK I think, but it was abandoned prematurely I think.

I'm very familiar with AutoIT. For some reason I didn't even think about using it! (if you're not familiar with AutoIT, generally speaking it's quite a bit better than AHK if only because of it's BASIC-like syntax, so give it a try!)

I'm a little surprised nobody chimed in with a .Net library that nicely wraps all of the things AHK and AutoIT do.

I've been learning Prolog (as a hobby - I know formal logic at a pretty high level so it seemed like a fun diversion), and I'm stumped on how to do something. I'm trying to use Prolog to parse a list (it's a list of Pokemon followed by all the moves they have - I'm trying to make an expert system) of the form [pokemon_name,move,move,move,pokemon_name,move,move (etc)]. I understand perfectly well how to do this if the number of moves were the same for every pokemon, it'd be something like: code:

There are a lot of difficulties here in any language. Your options are basically: 1. Maintain a database of Pokemon names and disambiguate when you hit a Pokemon name 2. Encode the number of moves in the field after the Pokemon and switch parsing based on that 3. Pad the fields to 4, with a flag like NoMove Based on my recollections of Prolog, 1 is rather difficult, but 2 and 3 should both be fairly straightforward.

I've used cmusphinx for a small voice-command project and it worked very well. It'll run on the the raspberry pi 3, and they've already collected all of the extra data you need. On Windows though, the Microsoft speech system is super good, accurate, and way easy to use.

Hey dudes. I noticed that there aren't any proper epub3 readers in existance. There are some that claim to have epub3 support, but only include a subset of the features. So I was thinking about trying to make one. The basics of rendering text from an epub is similar to HTML; could I use electron (a NPM/chromium platform for desktop apps) to do the heavy-lifting of the rendering?

Yes you can probably make that render most paged and continuous flow content in a reasonable way. You may have to transform the data in a non-trivial way to make everything work. As long as you don't assume you can just feed it in, apply a simple stylesheet, and be done, you should be okay. When making a document reader, also be extremely wary of the potential for exploits. Full-privilege code execution, affecting the application UI in unintended way possibly tricking the user into doing something they wouldn't, content that could render differently depending on context (e.g. screen/print, or depending on device resolution), and lots of other classes I don't know about/can't recall. Assume that users will expect your program to be secure and well-behaved, and expect to receive data intended to break your code.

Looking for the term for this kind of packing problem or the name of the algorithm to solve it. Given X sinks and Y Faucets where each faucet can flow into 3 specific sinks. Fill each sink up to a certain amount using the least amount from each faucet. (Or maybe minimum total, I'd want to play with both)

ultrafilter posted:What about this problem is under your control? Presumably how much each faucet is used. So like if faucet A sends 10% of its output to sink 1, 50% to sink 2, 40% to sink 3, you can dump 1L of water from faucet 1 and have 100ml/500ml/400ml in the three sinks. This sounds kind of like a packing problem to me.

In a sense, I guess, but it's a continuous packing problem and so very different in practice. You have coefficients Flow_{f,s} for faucet f and sink s, the constraints \sum_{f \in F} Flow_{f,s} Time_f >= Capacity_s, and want to minimize... something about Time_f. Sounds like textbook linear programming.

Yep Linear Programming it is. https://msdn.microsoft.com/en-us/library/ff628587(v=vs.93).aspx Looks like .NET even has a constraints library that will let me set it up really easily. Too bad, was hoping it'd be a bit more code to bite into for the break but rather have it done then reinvent the wheel.
