What graphics interface/api came after mode13h? Posted: 03 Nov 2018 03:52 PM PDT So in the 80s and early 90s if you wanted to write a DOS GUI application you'd use 16 bit real mode and use int 10h with al set to 0x13. You'd have a 320x200 screen to draw on in pixel mode. What graphics technology succeeded this? submitted by /u/lanzaio [link] [comments]

Opening a YML file with Java Posted: 03 Nov 2018 07:30 PM PDT I have a YML file I'm opening with events that have characteristics, is there a better way to extract them rather than reading everything into into a List then dealing with each line? tasks: - id: 1 description: Thing 1 start: "08:30" duration: 30 compatibility: - 2 - 3 - id: 2 description: Thing 2 start: null duration: 20 compatibility: - 1 - id: 3 description: Thing 3 start: "08:40" duration: 15 compatibility: - 1 Edit: Currently using the following to parse the YML - try (Stream<String> stream = Files.lines(Paths.get(fileName))) { list = stream .filter(line -> !line.startsWith("tasks:")) .map(String::trim) .collect(Collectors.toList()); } catch (IOException e) { e.printStackTrace(); } submitted by /u/corwin_of_amber_ [link] [comments]

Cold Pinky Fingers while programming Posted: 03 Nov 2018 10:03 PM PDT I totally understand if this gets removed because it isn't exactly programming. But just throwing this out there; does anyone else get cold pinky fingers while programming? I've been sat here at home programming for about 6 hours, and I've just noticed my pinkies are freezing cold. I wonder if my lack of using them causes them to go cold? My left pinky tends to do left shift only, but right doesn't really have a job. While the rest of my fingers and thumbs all have areas of the keyboard that they use. ​ It's also 5am (as I say been programming since 11pm), so apologies if this is a bit of an odd post; I don't feel 100% with it! submitted by /u/Dowzer721 [link] [comments]

Is Git Bash as effective as using the Bash Shell on a Macbook? Posted: 03 Nov 2018 10:02 PM PDT I'm going to be attending a coding bootcamp very soon, and they heavily recommended me to use a Mac because most of the testing environment is going to be done via the Bash Shell. I have Git Bash installed into my Windows laptop, so I was wondering if that'll do the job. submitted by /u/k-hiroshi [link] [comments]

[Prolog] How to compare two variables. Posted: 03 Nov 2018 10:02 PM PDT I'm writing a definition that compares the birth and death date of two individuals to see if they were alive at the same time. This is what I have so far contemporaryOf( Person, Contemp ):- lifespan( Person, BornA, DiedA ), lifespan( PersonB, BornB, DiedB ), I'm not sure how to actually compare the Born, and Died variables inside of lifespan, would someone be willing to help me out?

[Android] Is there any way to see what URL is requested by pressing a button? Posted: 03 Nov 2018 03:01 PM PDT Dumb question probably but is there any way when I'm in an app and I press a button to see what URL is requested by that button press? Is there any way to inspect that? If there isn't, theoretically we could still inspect the bytecode and based on that difficultly but get access to the URL that is requested or am I totally wrong? submitted by /u/dont_mess_with_tx [link] [comments]

Send fax automatically with one click? Posted: 03 Nov 2018 08:48 PM PDT I occasionally need to use an incoming fax # (very low volume) and the only free solution I've found is an online service. The downside (in addition to low maximum incoming volume, which isn't much of a downside since I don't use it much) is it needs to receive one fax per week to remain open. Is there a way to send a fax to a number with one click of the mouse, perhaps using one of the numerous free fax sending services on the web (some of which don't even require an image to check for robots)? submitted by /u/GetInHereStalker [link] [comments]

Python Image Tracer Posted: 03 Nov 2018 04:22 PM PDT I am trying to create an "auto rotoscoper" of sorts in Python and for that I need to trace each frame of a video to make an animation.

Floating Point Standards Posted: 03 Nov 2018 05:14 PM PDT Hi all, We've covered floating point binary as part of the computer science A-Level curriculum, and I went away today to look some stuff up to be greeted with information that, in-part, contradicts what we've learnt. We're taught as follows: First -> Nth bit = mantissa (-(20), 2-1, 2-2, 2-3) Nth -> last bit = exponent (-(2x), 2x-1, 2x-2 .. 2x-x) Both are signed as two's complement binary, and the mantissa can be normalized. Mantissa is then multiplied by 2 raised to the exponent However, looking online, people state the IEEE 754 is prominent, which has the first bit as a 'sign' (which also appears to contradict what we're taught of the use of two's complement being prominent and highly beneficial over sign-magnitude), the next N bits as exponent and then the final bits as mantissa. Have I mis-read the IEEE 754, or are there multiple 'standards' by which people run, or is this just a general misinformation? Are there significant advantages to one or the other? Looking around, people agree this is what's on the A-Level specification and not the IEEE 754 representation, so I'm certain it's not misinformation that'll drop me marks.

[Java] Changing the value of multiple variables by changing only one field. Posted: 03 Nov 2018 09:32 AM PDT I have a large collection of doubles and in this collection there is a subcollection of special variables that are all initially set to the same value. After some time I want to change the value of all of these special variables, but for efficiency I also don't want to iterate over the entire collection and change them one by one. I've tried using the double wrapper class, but apparently it's immutable, so I cannot just reference one instance of Double and change that. I thought about making my own mutable double wrapper class, and this works, but ideally I want the code to be as compatible with the primitive type double as possible. Is there any way to do something akin to this following C code in Java? int a = 0; int* b = &a; Here I only have to worry about the dereferencing. submitted by /u/kjQtte [link] [comments]

Getting out of a pair of quotes in Visual Studio 2017? Posted: 03 Nov 2018 10:17 AM PDT I'm just learning UWP, and I'm having to write a lot of " for the XAML.

Additionally, this method doesn't seem to work: https://stackoverflow.com/questions/13947886/how-do-you-move-the-cursor-past-the-closing-quotes-when-typing-property-values-i Anyone got an answer for this?

[Python] Function to print dictionaries with an unspecified amount of dictionaries as parameter Posted: 03 Nov 2018 01:38 AM PDT Hey folks, I've kind of hit a wall here. What I'm trying to create is a function that will first print the title of a dictionary and then below that every key of that dictionary together with it's value. It should be able to do this for an unspecified amount of dictionaries, My current solution is to first give a list of names as a parameter and then use *args to input the dictionaries. As you can see here in my code: https://github.com/mauritscottyn/eigenOef/blob/master/oef3.py Now this works just fine but I find it is very prone to user errors as it fully relies on the user entering the names in the list in the same order he inputs the dictionary into the function. So what I'm looking for here is a way to integrate the dictionary names better into my function so that it won't be reliant anymore on the user entering everything in the right order. I hope I was able the phrase my question kind of clear, English is not my first language. Thanks! submitted by /u/mauritsc [link] [comments]

Best way to store this data? SQL or Json? Posted: 03 Nov 2018 08:47 AM PDT Hey guys, I am working on a little project that will be a guide for a video game. Basically I want to show where every item in the game is located in a nice web ui. I don't do much SQL so was wondering if there was a better way to store this information. It basically looks like this right now. "Items - id, name", "Maps - id, name", "ItemLocations - itemId, mapId". The trouble is when I go to add a new item/map to the ItemLocations table, I have to scroll through hundreds of mapIds to find the correct one. There aren't nearly as many items, so that part is easier. Is there a more efficient way of doing this? Thanks in advance! submitted by /u/roflsausage [link] [comments]

In my Bash script, splitting strings is leading to odd results. What am I doing wrong? Posted: 03 Nov 2018 12:16 AM PDT Here is my script: https://paste.kde.org/phtyebw6h I have a file that has a list of packages in the order I wish to build, but I want selected packages to built in their default directory on the harddrive, so I don't have to recompile, say, 2200 files from scratch, but only recompile what changed. Otherwise, they build in tmpfs. If the line being read has :1, it gets compiled on the harddrive, otherwise if not, on tmpfs. Example file: https://paste.kde.org/pu8ebcozv The maddening thing is, if that :1 exists, then all lines that are next looped over are built in the harddrive directory, and not tmpfs. Even if I unset the variable or set it to empty, this still occurs. submitted by /u/Valmar33 [link] [comments]
