Just as a jot, a tool to access SSH shares via SSHFS on Windows: win-sshfs. It gives you a drive letter, instead of fiddling with separate tools to access files.

Some time ago, the Firefox developers decided it was a good idea to trim the http(s):// from the address in the address bar. Since then, I’ve been getting HTTPS site where I don’t want it, because I can’t see what I’m doing. Especially so because HTTPS has no concept of virtual host names, and putting https:// in front of any domain might put you on a completely different web site. So, when I accidentally typed https:// in front of an URL once, it will remember that, but not show me…
Luckily it can be disabled, by setting browser.urlbar.trimURLs to false in about:config.
This annoying feature is right up there with the removal of the RSS icon from the address bar.
Noting this down to not forget.
The Logitech HD Webcam C270 is a cheap webcam that is simply a USB video device, so it works in all OS’s without special drivers.
There are a million 20×2 characters LCDs out there, but this is one that I like:
- http://www.okaphone.com/artikel.asp?id=475234
- Farnell code: 9448780
It has a metal frame that fits my cross-over front panel, and the metal frame is shiny silver. And, the screw holes aren’t grounded.
When I booted my system with the webcam plugged in, it was sound device 0, instead of 1. This is annoying, so I added this to /etc/modprobe.d/alsa.conf:
options snd slots=,snd_usb_audio
This forces the usb sound module to take second place.
Like this, but then with bonding:
# The loopback network interface auto lo iface lo inet loopback auto bond0 # The primary network interface iface bond0 inet manual slaves eth0 eth1 bond-mode active-backup bond-miimon 100 bond-downdelay 200 bond-updelay 200 auto xenbr0 iface xenbr0 inet static address 1.2.3.4 netmask 255.255.255.0 network 1.2.3.0 gateway 1.2.3.4 dns-nameservers 1.2.3.4 5.6.7.8 bridge_ports bond0 bridge_fd 0
I needed it because I had have a dedicated server that was setup with ethernet bonding that I wanted to install Xen on. Normally, you can let xen setup the network with “network-script network-bridge” in /etc/xen/xend-config.xsp, but that doesn’t work when you have bonding. And, it’s actually better to do it with Debian’s netconfig anyway.
It’s that time again…
First my grub broke. So I had to type my config manually:
root (hd0,0) kernel /vmlinux26 root=/dev/mapper/lvmopraid-root initrd /kernel26.img boot
Then my logical volumes can’t be found. Type this in the recovery shell:
lvm lvchange -a e lvmopraid
I commented on an archlinux bug about this.
And then nothing started anymore on boot, because everything is migrating to systemd (as opposed to systemv), without telling me… Still working on fixing that.
#!/bin/bash -e trap "echo ERROR HANDLING HERE." ERR echo "Starting" asdfasdf echo "End"
And when you run it:
Starting piet.sh: line 5: asdfasdf: command not found ERROR HANDLING HERE. End
For the record, about chemical tin PCB treatment:
Whenever one of the servers in /etc/resolv.conf is unreachable, Linux/glibc/whatever isn’t smart enough not to retry it for a while. This results in a lot of services becoming unavailable, because a lot of them do reverse lookups on all incoming connections (like SSH), which will hang for the time-out of the first DNS server query.
There doesn’t seem to be a solution, but I worked around it a little bit by putting this in /etc/resolv.conf (or /etc/resolvconf/resolv.conf.d/base && resolvconf -u):
options timeout:2 rotate
Still not perfect, but more workable.
