This is more web dev question but couldnt find the thread. Really need help with this. So I'm working on a project and my job is to create the UI (so it looks like the screenshot).
He said i will have access to the API later so i can get all the data and statistics. I know about divs and tables and all of that, but how would i go about coding this to get it look like this mock up? It looks like a infographic.
Any help with this would be greatly appreciated.

Hey /g/ I'm writing an android app for a project and I am absolutely baffled as to why this is throwing an error.
We have a login screen with a create new account button, and the onClick method for said button points correctly to the right method. The method creates an intent and starts the activity but when it actually calls startActivity() it crashes and throws the exception "Could not execute method for android:onClick".
I don't understand why, because the create new account button correctly calls the method and creates the intent with no issue. Googling points me to the obvious results, but there is no onClick method called after the button is pressed. what is going on here?

for example[0, 0] = 10
[0, 1] = 3

[1, 1] = 2
etc
but now based on values I would like to find what value is in point
[1.30, 0.15]

ruby is a language, rails is a web framework. ruby is a perfectly good language in its own right even though it has a lot of really dumb stuff in it as well
java is still very heavily used for backend systems, but if you don't want to be part of the javasphere because you don't want to compete with h1bs then you should be good with languages in general, not a single language.

I know y'all get this question a hundred times a week, but I've lurked for a couple weeks now and have yet to find a definitive answer.
Where should I start /dpt/?
What language should I dive into? Java? C++? Ruby? I've heard these 3 spouted like gospel from various sources. Heard ruby is good for beginners, C++ has great resources, and java is used in fucking everything. Which would be the best starting point?
I've taken a class that focused on VB and Alice, thought it was garbage, blew through the class and moved on.
Looking for something I can do on my own time, budget, and would actually be worth my time. (ie: pick it up at my own pace fast or slow, free or cheap resources, logical jump to other languages, in decently widespread use) I guess I'm just worried I'd spin my wheels trying to jump straight to C++, lack resources for java, or find no demand for ruby.
Merits or flaws of each are appreciated, or let me know if I overlooked something.
Tl;dr ruby, java, C++. Whats the best use of my time as a newbie?
C noob here, I'm starting to write small C programs, in particular my dwm status bar.
(My god, the memory usage is actually less than 500KiB compared to the python equivalent of 9 MB)
Im such a novice though. Is there a better way to get an output of a system command and evaluate it in C? For now, I trigger a bash script to write to file, then I use C to open file and get the output from the file. I know this is wrong and probably not the best practice.
TLDR; Best way to get a system command's output and possible evaluate and parse it
Here's my code for getting the cmus now playing as an example:char *

char *co;
char str[12256];
char PAUSED[400];
char STOPPED[400];
int ret;
system("bash /home/marche/bin/cmus-np.bash > /home/marche/.np");
co = readfile("/home/marche/", ".np");
if (co == NULL) {
return smprintf("");
}
sscanf(co, "%[^\n]", str);
free(co);
strcpy(PAUSED, "paused");
strcpy(STOPPED, "stopped");
ret = strcmp(str, PAUSED);
if (ret == 0) {
return smprintf("\uf04c %s", str);
}
ret = strcmp(str, STOPPED);
if (ret == 0) {
return smprintf("");
}
if (strlen(str) == 0) {
return smprintf("");
}

Assembly
>>51635468
system() is pretty shit. Use fork() and execv(). If you want to get the output of the program (stdout) of that program back in your main program, you'll need to create a pipe() and then redirect stdout of the child to it using dup(). It might be a bit overwhelming for a total noob, but there are actually heaps of tutorials online for this sort of thing. Just search for "C how to use fork()" or something.
They're not 'C standard', but they are 'POSIX standard'.
I also think glibc might do this all for you, but I don't remember what they're called and I don't use it.

> What interpolation method would work the best in your opinion?
Define "best".
Interpolation is one of those subjects which could easily fill a bookcase. You could fill a book with just the basics.
The main thing is that you're very limited in what you can do if you need to be able to sample near the edges. Most of the better algorithms require more than just the values on either side (i.e. 2 values for 1-D interpolation, 2x2=4 for 2-D, etc).
If you can afford a 4x4 window (i.e. the interpolation point will always be at least one cell from any edge), then cubic interpolation provides first-order continuity (i.e. you don't get obvious banding).
Given a value x, you determine y=f(x) byi = floor(x) // integer part
f = x - i // fractional part
// determine Hermite spline
y0 = f(i) // value below
y1 = f(i+1) // value above
dy0 = (f(i+1)-f(i-1))/2 // derivative below, f'(i)
dy1 = (f(i+2)-f(i))/2 // derivative above, f'(i+1)
// determine cubic polynomial coefficients
c0 = y0
c1 = dy0
c2 = 3*(y1-y0)-dy1-2*dy0;
c3 = 2*(y0-y1)+dy0+dy1
// evaluate polynomial
y = c0 + f*(c1 + f*(c2 + f*c3));
This is separable, i.e. in 2 or more dimensions, you just interpolate in each dimension in sequence. So for 2-D, you take a 4x4 region, interpolate each row of 4 values using the x coordinate, then interpolate the 4 interpolated results using the y coordinate.

Hello thread, I am not entirely sure if it's the right thread to ask for advice but I didn't find another related with my problems. Also, please be gentle.
I graduated last year on Computer Science, I have worked with mobile development (using Xamarin) but since I graduated I have been studying by myself about native android development and I just really like it, more than I liked developing using Xamarin. So I got fired from my job and I am struggling to find another job (mostly because I am searching for native development jobs, not Xamarin ones).
I really wanted to keep myself active by developing apps by myself but I have a few problems doing so. First I just can't get myself to think about an app that I could develop, I don't have any idea of what do to. Second is if I want to create a more elaborated app, I will need a service to fill it with data, and I simply can't afford to buy a server just to host it.
Are there any android developers out there that could give me a light?
TL;DR: Newbie Android Developer needing to find a way to keep active while struggling to find a new job.

Once you reach the end of the list, there will not be a y+1 for you to access. Either add a check that will tell you if you're at the end of the list, or come up with a better function.

In your loop you bring it down to 9, so your loop will run from 0 to 9. But once you reach 9, guess what y+1 is trying to do? 10, and distro_info[10] won't work.
I recommend doing something like this if you want to access indices.for index, value in enumerate(distro_info):
if index != len(distro_info)-1:
# do a thing that does y+1 here
enumerate() produces a list of pairs, the first item
being the index and the second being the value.
>>51637741
>>51637714
Nah, you should do -2. One for the last item on the list, one for starting from zero instead of for one.

I wish most of these weren't just weird, esoteric math problem solvers.
>>51637779
Instead of running a conditional each loop, just go through the list, but skip the first element, and use y-1 instead.

Hi /g/
How do I make an empty JList display as an empty box? Right now my empty JList displays as a tiny dot in my GUI, but I need a large white box. Even setting the fixed cell width and height doesn't fix it. Any clue?nameList = new JList <String>(Names);
nameList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
nameList.addListSelectionListener(new ListListener());
JScrollPane scrollPane = new JScrollPane(nameList);
scrollPane.getViewport().add(nameList);
thisPanel.add (scrollPane); //a JPanel
nameList.setFixedCellWidth (275);
nameList.setFixedCellHeight(275);
nameList.setVisibleRowCount (9);
thisPanel.add(nameList);

Create a seperate pane and use setPrefferedSize(new Dimension(275,275);
and add that panel to your thisPanel.

>tfw I only know VB.NET
should I just give up?
it seems the .clone() function is broken and not a good idea to use it. So no problem I write my own clone method. The only Problem is that I have an interface instance in my Object.public class Foo{
public TestInterface test;
public Foo(TestInterface test){
this.test = test;
}
}new Foo(new TestInterface(){
//do stuff
}
how do I duplicate the interface instance without clone? the instance might have some private variables and just passing a pointer is not an option. Or did I miss something?

Well if you are forgetting stuff I'd put it into a Makefile. It really does make shit easier.
Porting a bunch of functions from the existing perl codebase at work to C++ to give things a speed boost when running on largeish data sets. I've overcommented because the source I'm working from is at least 15 years old, has 0 comments and I find perl a bit cryptic at the best of times; I don't want someone to come along in another 15 years and wonder what prick wrote a load of uncommented code that they now have to port. It's mostly checksum generation/validation with patient numbers, sample IDs etc.

thats because it detected what you were trying to do wand was writing your html for you
>>51637566
You're approaching this a little wrong which makes coding complex.
distro_info should be a list of lists, like this:
#sample data file1,2,3,4,5
10,20,30,40,50
#sample distro_info[
[1, 2, 3, 4, 5],
[1, 2, 3, 4, 5],
]
If you throw away all your code and rewrite it like this, it should be much easier.

Any DBA's present?
I'm in the process of designing a database structure for a project, and I'm wondering how performant using a GUID-Token system as a unique ID across tables is.
I.E. All the characters on a map, the map itself, all the players involved, all have a shared GUID in their respective rows in their respective tables, so when you load up any given game it runs a query to pull all the records with that GUID to pop in all the info.
But I'm wondering if there's a more efficient way to do that

It's called clang because it's the sound it makes when you drop it after it failed to compile your standard-compliant program, again.

Nothing about java is inherently bad, but it has a lot of very well documented negatives because of how long it's been around.
It's not a bad place to start, or to code in general, because of the wealth of documentation that exists and the amount of industry that uses it.
But, if you can help it, just use C#. It's Java refactored by microsoft, which makes it exactly as efficient (I.E. Not) but way, way fucking cleaner to write with.
LALRPOP (a Rust parser generator) is broken on the latest nightly, so I can't work on my latest project. To pass the time I am writing a monadic parser combinator library since I've never actually used one before and I thought making one would give insight into them.

>>51639651
Let me rephrase:
Well documented complaints.
All languages have inherent negatives to them. Java is bloated, memory inefficient, and will quickly spiral out of control into single object factory page enterprise spaghetti code.
That said, overall, it's a solid language.
