There is at least three places you need to set the maximum upload file size in WordPress.
First check your php.ini
upload_max_filesize = 64M;
post_max_size = 64M;
Restart Apache after making this change.
Then if you are using WordPress multi-site, you need change a setting in the backend. Visit My Sites -> Network Admin -> Dashboard -> Settings -> Network Settings. Then scroll down to the Upload Settings area and change that.
Thanks to dorr13 for that tip.
From time to time I need to create an init.d startup script for a program that is not part of the default debian distribution. I’ve always found it unnecessarily fiddly to create a new script. The other day I came across naholyr’s gist, a script to make init.d scripts.
There were a few problems with it so I made it into a proper github project and fixed up the problems. The url it was retrieving the service.sh script from was 404, and it wasn’t checking for successful download of the script, so I made it abort if it fails to download.
I couldn’t come up with a decent name for it so its called sample-service-script.
I already had a few pull request to it, yay!
I finally wired up the big LEDs and made an acrylic mounting board for all the parts. I laser cut holes in the board and tapped them with an M3 tap. That allowed me to mount the circuit boards directly to the mounting board. I used Dupont connectors to wire everything up which gives a very neat finish I think.
If you ever need to do a factory reset on a Yealink phone, maybe if you forgot the admin password, simply hold the OK key down for 10 seconds and follow the prompts.
Thanks to Langineers for that tip.
Sometimes you want to preserve file permissions under subdirectories in linux with ACLs but that’s not the whole story. If you want multiple users to be able to read and write to these files, and the group permissions to stay correct, you need to set ACLs and also group +s on the subdirectories. This is to ensure new files and directories are also created with the correct permissions and group ownership.
I wrote a small script that takes a group and a directory as parameters, and recursively fixes the permissions and set new ACL and group permissions so in future, new files will have the correct permissions.
I put set-acl-permissions on github.
It blindly recursively sets permissions so be careful. Also, it may well contain bugs that could cause catastrophic failures.
A while ago I broke my favourite mug. After a long and difficult search I found a new mug. A mug with the periodic table of elements entry for uranium on it. It also glows in the dark. Gav from the hacker space has a Geiger counter so I took the opportunity to measure the radioactivity of my mug. Luckily it’s not radioactive at all. Only 0.106μSv/h (micro Sieverts per hour).
Sometimes you might need to copy a whole directory from a remote host, but the remote host does not have enough space to tar the whole thing up and then sftp it off. The solution is to tar/bzip the directory and stream it directly to your local host:
ssh root@remotehost 'tar cjf - /path/to/somedirectory' | pv -cN tar > somedirectory.tar.bz2
Using pv (pipe viewer) gives you extra progress bar goodness:
tar: 176MB 0:09:14 [ 371kB/s] [ <=> ]
I’ve been on a quest to find a good remote for MythTV. My first try was with a Logitech Harmony. Those things are nasty horrible pieces of crap. I’d never touch one again. Programming it is a nightmare. It does not have a generic PVR option so you have to fake it to make it work with Mythtv by telling it its another device and learning those codes in LIRC. It is a very slow device with what felt like a 500ms delay with each keypress. It also tried to know what state your equipment was in so that it could turn things on and off, but of course it would always be out of sync and then you’d have to go through this process of turning things on and off until it was in sync again.
Enter the HP MediaSmart IR remote, also known as HP RC2285202/01. These devices used come with a media player box that HP used to sell. As far as I can tell, its not in production anymore but the remotes are readily available on Ebay.
Features:
There are a few downsides too:
I spent many hours trying to work out why it would not work on my system. In the end it came down to two things.
For some reason LIRC does not work correctly with MCEUSB receivers that are plugged into USB3 sockets.
You need to tell the kernel to treat the receiver as lirc rather than anything else, in order for LIRC to be able to connect to it:
$ sudo sh -c "echo lirc > /sys/class/rc/rc6/protocols"
$ sudo cat /sys/class/rc/rc6/protocols
rc-5 nec rc-6 jvc sony mce_kbd [lirc]
The word [lirc] surrounded with square brackets tells you it worked.
I implemented this at boot time by adding
/etc/rc-scripts/start-lirc
to /etc/rc.local and then in /etc/rc-scripts/start-lirc
#!/bin/bash
echo "Making lirc the default for rc"
echo lirc > /sys/class/rc/rc0/protocols
echo "Starting lircd"
/etc/init.d/lirc start
Remove lirc from the normal startup process:
$ sudo update-rc.d lirc remove
Test your configuration (retrieve HP-RC2285301-01.conf below):
$ sudo /usr/sbin/lircd -n -d /dev/lirc0 -P ./lirc.pid HP-RC2285201-01.conf
$ irw
And when you press the keys on your remote, you should see some output from irw.
