semget: No space left on device N次遇到这个问题

This relates to semaphores on your system (you’ve run out). Run the following to clear them out:
ipcs | grep apache | awk ‘{print $2}’ > sem.txt
for i in cat sem.txt; do { ipcrm -s $i; }; done;

If this becomes a common occurance, then you may need to change your ipcs semaphore limits.
Set the following in your /etc/sysctl.conf:
kernel.msgmni = 1024
kernel.sem = 250 256000 32 1024

and reboot your system to load in those values. 继续阅读semget: No space left on device N次遇到这个问题

www.BOIP.net 的IP信息图片调用

Over the past year, we’ve been working hard to create a new look to DirectAdmin. We’ve called this new skin Evolution.
This new skin will have a similar feel to our new directadmin.com website.

We’re very close to releasing a public demo, so you can keep an eye on this page, and we’ll update it once we have more information.

Make skin responsive (css resize for tablets)
Admin Backup/Transfer
Translations (to be done during alpha testing)

After we get some feedback about the demo and finish up a few lose ends, we’ll release an Alpha version for general testing. After that, a beta, then the full release. For each step, if anyone is testing on their system, be sure to grab the latest pre-release binaries, as major internal changes have been made in DirectAdmin to accomodate the new skin.

全新的进化SKIN, 很快和大家见面

[FFMPEG] take multiple screenshots to an image

To make multiple screenshots and place them into a single image file (creating tiles), you can use FFmpeg’s tile video filter, like this:

ffmpeg -ss 00:00:10 -i movie.avi -vf 'select=not(mod(n\,1000)),scale=320:240,tile=2x3' out.png

That will seek 10 seconds into the movie, select every 1000th frame, scale it to 320×240 pixels and create 2×3 tiles in the output image out.png, which will look like this:
