Rigged Death Trap posted:I'm starting a computer science course later this year and I was wondering, since I am wet behind the ears on programming, what stuff I could read up on to begin with? If you want a leg up on your course, it probably wouldn't hurt to read up on a few sorting algorithms. Try quick sort and bogo sort and please skip bubble sort. vvv If you want real-time, free is mutually exclusive to good. Actually free+good basically doesn't exist for market data at all.. leper khan fucked around with this message at 20:58 on Jul 29, 2012 |

soapydishwater posted:Thanks for the advice everyone, it really helps (even Bognar's "word vomit"). That part about the interface driving the logic from Nielsm made a lot of what I already know click into place. To narrow the scope, by the way, I was mostly taking about a desktop, GUI sort of application, since I've been wanting to write my own image editor for a while- but like I said, I wasn't sure where to start. I'm sure there's more specific stuff that applies to image editors, but I can probably figure it out myself. Start with pen and paper. This may sound strange, but it will lead to better results faster than everything else. At least it has in my experience.

Snak posted:So basically all my problems with this entire project are caused by the way the files are set up. I don't know how to avoid duplicate definitions because, there are supposed to be four files of source code, which can be assembled in different combinations using a makefile. I can't put my includes in just one of the headers because not all combinations use all the source files. This project is a nightmare. Please tell us more in the horrors thread. Also I don't understand why you can't have more than four files? Or why it's desirable that including in different orders changes behavior.

Hughmoris posted:Thanks for this. I have a feeling that it is a local app that generates html. The software is something similar to the Epic EMR package. The kicker is that I'm 99% sure that all the application is doing is writing my entry to a database table. I know jack poo poo about databases but that means if someone had write access to the database, then they could simplify all of this by creating a script that would write the results directly to the table? This time-sucking project would be completed pretty drat fast if that was the case. As it is, we are having to touch over 1300 medications by hand. Connecting straight to the DB is probably a bad idea. The application could be altering some data you don't notice at which point you've forced the DB into a bad state. Boot up wireshark; hopefully it's simple http queries.

Fisticuffs posted:Cool, then I will definitely look into customizing someone else's base into something that can hopefully offer similar quality to ESPN3. Thanks for this info this is really awesome. Do you know of any open source databases, search engines or basically some site that'll help me locate these programs and start vetting them for my needs or looking into how customize-able they are? Thanks again for the help everyone! Just to be clear, you're trying to break into a crowded market with absolutely no understanding of the underlying technology. I hope you have a lot of money that you're willing to burn. If you're really looking into this, it might be better to read the RFCs on streaming web content before looking for half fleshed out services. If you want something minimal though, you can probably just host full videos and play them on a site with an html5 player. Live-transcoding content can probably be added later.

PRADA SLUT posted:I have a text file with lines of data. I want a script that will enter the first line into a text box on a website, hit enter, wait 5 seconds, enter the second line, wait, etc. I've done similar things in C#; it's pretty simple, just look up the API for emulating mouse/keyboard events on the MSDN. You can "type" by passing strings, etc. Depending on what you're actually doing, it may make more sense to just use curl to directly send web requests though.

dupersaurus posted:I was involved with a (much smaller that wow) mmo a few years back, and I'm pretty sure it was some flavor of SQL. The whole game state is loaded on startup and kept in memory, so it's not like you have to be constantly pulling and pushing into the db. The MMOs I've worked on all used MSSQL. They weren't at WoW's scale, but there's nothing wrong with RDBMS. Especially when you know the form data should have (as with most problems in games).

It's also indicative of the type of place where there's an incompetent in a position of minor authority that will "correct" valid terms with whatever nonsense lives in their broken mind. Guaranteed HR isn't arguing semantics of terms if an engineer tells them it's something other than what they were saying previously. People in recruitment are shockingly good at parroting.

it is posted:I wanna write something to scrape manta.com (a directory of local businesses) for work. I started but my rough draft got sniffed out by their security. The site is clearly designed to be crawled, but what are some best practices to make sure I can get the information I'm looking for without getting in trouble? It depends? Easiest thing to do is ask for their data (they won't give it to you). Failing that, you can write your crawler to distribute scraping tasks to multiple machines and make sure any given machine doesn't make calls extremely quickly or at precise intervals. Eg, use a bot net. I don't know what "getting into trouble" means to you. If you don't want to get your bot shut down, try to mimic human actions. If you are worried from a legal/ethical standpoint, maybe don't do a thing. Basically don't piss off their CJ's and even if they catch you they may not care enough to bother dealing with you. But if you interfere with the operation of their site by DOSing them, they'll very likely blacklist you.

For erlang there's a bunch of books on structuring things in OTP containers I guess.

Jsor posted:I was looking over one of my old wrappers, and I'm wondering how you all would handle something. The library I'm wrapping only has one way to load or save a type: calling a function with a string pointing to a file destination. However, I want my type to be serializable using the language's serialization feature. You almost certainly don't need to write a file, the ease of doing so depends on the language you're using and if you have source access to the underlying type. What you have is a straightforward workaround for a seemingly bad API. It sounds like the simplest alternative is a memcpy, but I can't know that there aren't hidden types allocated that you would probably need to replicate as well. e: You may want to look into how your language handles reflection. leper khan fucked around with this message at 12:52 on Sep 13, 2016 |

If you did need to do that, I'd probably set up predefined tasks or something.

Minorkos posted:hi I've recently started studying computer sciences after bumbling around in humanities for a couple of years. I did some research and it turns out that this degree will be largely worthless as well unless I really put some effort into learning programming and stuff at home as well. we've done a bit of programming in C# at my college already but it's all been extremely basic and easy stuff, and I want to really learn a lot of stuff fast. seeing as I'm already in over my head, what would you recommend for a person such as myself? I'd like to do something that starts out somewhat easy but can be built upon from there. I was thinking of making some dumb project in Unity or something like that, but I don't know if that's a silly plan. Maybe go through some C# tutorials? i don't know Unity is fine, but be sure to stick to a project that seems far too simple to start with. Minesweeper/Tetris/etc. You'll find a number of people with a similar background to yours in the various game dev threads, but many have strong technical backgrounds as well. Those threads are also generally open to people starting out.

cubicle gangster posted:I work for a marketing agency that creates interactive experiences and sales galleries and have a question about time/pricing. have a client asking for a ballpark timeframe/cost, for something we & they know we'd need to hire a freelancer for. Tell your client to provide an API to their database and you're basically done? Smart fox is probably the wrong tool due to both cost and complexity. All you need is a web API with preconfigured queries into the database. If you don't have DB experience in house, you may just want to ask your client for the API, unless you want to get stuck with support contracts you'll continuously feed to random people. It shouldn't be terribly complicated, but I also don't know what kind of nightmare their schema is. I would expect the contract for that bit to be less than a month at whatever mid level dba's charge in your area. After the API is up, you can just pull things down using unity's WWW class.

csammis posted:Those methods are all about foreground-background subtraction which requires learning or being told what is "background" and what isn't. If you can assume that everything in the foreground that you care about is definitely moving in every set of images you analyze, then this may work for you. If you don't know (or can't determine) what "background" means in your image set then you may want to look into object tracking. In OpenCV this involves selecting a set of points, usually by a feature detection algorithm like FAST, and running it through one of these methods. Are there any libraries other than kinect for grabbing 3d pose information for humans out of an rgbd image? Looked around but couldn't find anything. If not, a short reading list would be appreciated if you're familiar with the domain.
