Interestingly, using -fdata-sections can make the literal pools of your functions, and thus your functions themselves larger. I’ve noticed this on ARM in particular, but it’s likely to be true elsewhere. The binary I was testing only grew by a quarter of a percent, but it did grow. Looking at the disassembly of the changed … Read more
Yes, Aero lies about the window size returned by GetWindowRect(). It is a rather important appcompat hack, without it far too many programs would have a client area that’s too small. Unfortunately there’s neither an API call nor a manifest entry that can be used to turn off the lie. The only way is to … Read more
It’s a constraint violation, and your compiler should diagnose it. If it compiles it in spite of that, your program has undefined behaviour [thanks to @Steve Jessop for the clarification of the failure mode, and see @Michael Burr’s answer for why some compilers allow this]: From C11, 6.5.3.4./1: The sizeof operator shall not be applied … Read more
This is a question crying out for a canonical one, really. In the interest of answering your specific question in the absence (as far as I can tell, but I may write one eventually), I’ll answer. The argument to size must not be an unallocated allocatable variable. For your code fred is an allocatable variable. … Read more
Setting -Xmx to one gig doesn’t mean that the JVM will allocate that much memory upon start-up. The JVM will allocate only -Xms (plus overhead) until more heap space is needed. Do you need to protect your users from thrashing virtual memory or a failed memory allocation from the OS? If not, just set Xmx … Read more
You can’t. This is normally done with dynamic memory allocation. // Like “ENEMY enemies[100]”, but from the heap ENEMY* enemies = malloc(100 * sizeof(ENEMY)); if (!enemies) { error handling } // You can index pointers just like arrays. enemies[0] = CreateEnemy(); // Make the array bigger ENEMY* more_enemies = realloc(enemies, 200 * sizeof(ENEMY)); if (!more_enemies) … Read more
Just an update (07-2014), as I’m not able to add comments: As correctly noted above, newer Express versions have deprecated the use of the limit middleware and now provide it as a built-in option for the BodyParser middleware: var express = require(‘express’) var bodyParser = require(‘body-parser’) var app = express() app.use(bodyParser.json({ limit: ‘5mb’ }))
I think this is because of a typo. Instead of upload_max_filesize = 7MB it should read upload_max_filesize = 7M use phpinfo() again to check what value actually gets applied.
The following bit of code does what you ask for. Just make sure that you assign enough space so that the text on the button becomes visible JFrame frame = new JFrame(“test”); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); JPanel panel = new JPanel(new GridLayout(4,4,4,4)); for(int i=0 ; i<16 ; i++){ JButton btn = new JButton(String.valueOf(i)); btn.setPreferredSize(new Dimension(40, 40)); panel.add(btn); } … Read more
que.add(d); if (que.size() > YOUR_LIMIT) que.poll(); or did I missunderstand your question? edit: forgot to mention that for this to work you probably have to invert your comparTo function since it will throw away the one with highest priority each cycle. (if a is “better” b compare (a, b) should return a positvie number. example … Read more
