If you encounter low disk space on Ubuntu (eventually on other Linux flavour), a useful program to find size of directories is baobab.
You might see that /lib/modules contains gigabytes of files related to old kernel versions. How to remove them? The answer is here:
apt install --auto-remove

Migrate a WordPress blog into HubSpot
There is a tutorial on how to migrate WordPress blog posts into hubspot. If anything more complicated is needed, e.g. to deal with language variants, here are some commands that will help to automate it. I am also offering the migration as a service.
The situation was that the original blog had language variants in the form of http://blog.company.com/2017/... (without any language specified) for English and http://blog.company.com/ru/2017/... for other languages (in this case, "ru" for Russian).
Therefore, we process English blog items separately:
{ xmlstarlet ed -d '//item[not(contains(link,"blog.avast.com/20"))]' all.xml; echo ""; } > all-en.xml
Other languages are processed automatically with the help of a loop:
for L in cs de es fr it ja pl pt-br ru tr uk ; do export F=all-$L.xml; { xmlstarlet ed -d '//item[not(contains(link,"blog.avast.com/'$L'/"))]' all.xml; echo ""; } > "$F"; sed -r -i "s:(<link.*blog.avast.com/)$L/:\1:g" $F; done
There are redirects to be set up in the HubSpot settings so that the old URLs are still accessible and they will point to existing articles (new locations). This helps to maintain ranking in search engines and does not break links from other sites.
# english without a cycle
L="" perl -ne 'if(/^http:\/\/blog.avast.com(.*),http:\/\/avast.hs-sites.com(.*)$/ && not ($1 eq $2)) { print "$1,$2\n"}' > redirects-languages.txt
# other languages
for L in de it fr ru pl pt-br cs es; do
perl -ne 'if(/^http:\/\/blog.avast.com(.*),http:\/\/avast.hs-sites.com(.*)$/ && not ("/'$L'$1" eq $2)) { print "/'$L'$1,$2\n"}' >> redirects-languages.txt
done
One may have to deal with CDATA:
CDATA tag replace in ViM:
:%s#\(<script.*\)// <!\[CDATA\[#\1#
:%s#// \]\]\]\]><!\[CDATA\[></script>#</script>#
With these commands, it was possible to migrate thousands of blog posts from WordPress into HubSpot.

:%s#// \]\]\]\]><!\[CDATA\[></script>#</script>#
When uploading new redirects (which is possible to do in bulk), we deleted the old redirects first. It is possible to automate it with an iMacros script:
VERSION BUILD=8940826 RECORDER=FX
TAB T=1
URL GOTO=https://app.hubspot.com/content/486579/settings/url-mappings
TAG POS=1 TYPE=SPAN ATTR=CLASS:dropdown-targetsettings-icon&&TXT:
TAG POS=11 TYPE=A ATTR=TXT:Delete
TAG POS=1 TYPE=A ATTR=ID:hs-fancybox-ok
TAB T=1
URL GOTO=https://app.hubspot.com/content/486579/settings/url-mappings
TAG POS=1 TYPE=SPAN ATTR=CLASS:dropdown-target
TAG POS=11 TYPE=A ATTR=TXT:Delete
TAG POS=1 TYPE=A ATTR=ID:hs-fancybox-ok
With these commands, it was possible to migrate thousands of blog posts from WordPress into HubSpot.

badblocks: says it is not safe to run and stops
Symptoms:
When checking for bad blocks, following error is displayed:# badblocks -nvs /dev/sdb
/dev/sdb is apparently in use by the system; it's not safe to run badblocks!
Solution:
- Check the mounts (/etc/mtab), unmount with umount
- Check the swaps (/proc/swaps), unmount with swapoff
- Check volume groups (/dev/mapper/...), deactivate with vgchange -a n

Dual screen in Ubuntu Unity/compiz
Besides what is obvious from configuring Displays, there is a useful shortcut that I did not find anywhere documented:
Start+P
All windows end up on the first virtual desktop though. I did not find a solution for that. One can set up rules in compiz (with the ccsm utility) so that specific windows appear on specific virtual desktops, appear maximized, etc, then noone can move them from that position.
Start+P
It cycles through different display configurations (for the built-in LVDS notebook screen and for the external display). Unity tends to forget the settings in some cases (suspending the machine, disconnecting from the display) and this is where the shortcut becomes useful.

Encrypted Ubuntu filesystem on a logical volume (without alternate install)
Ubuntu with LVM and an encrypted filesystem does not require the Alternative installation media. It can be done via the official one.
My setup is what is usually called full-encryption (although I would not call it full, because the /boot partition is not encrypted and thus it can be backdoored by someone who has physical access to the machine). The root filesystem is located on a logical volume and encrypted (unlike in other setups and how-tos where the whole LVM is encrypted). The boot partition is on the /dev/sda3 partition; it can boot other systems where I do not want to install LVM support.
If a newly installed system does not boot after a reboot and drops out into a busybox shell, it can be because the initramfs is unable to find root partition to mount and boot the rest of the system. This is what I have done to finalize the installation:
1. Boot another system (e.g. Ubuntu from the installation media)
2. Open the new (encrypted) target Ubuntu root filesystem
3. Mount it
5. Chroot to it
7. Edit the file /etc/default/grub and add kernel command line options
(GRUB_CMDLINE_LINUX="root=/dev/mapper/cryptroot cryptopts=source=/dev/vg/new")
so that after propagating the changes (update-grub) the generated grub configuration file (/mnt/boot/grub.cfg) has the line
(linux..... root=/dev/mapper/cryptroot cryptopts=source=/dev/vg/new)
You can omit the first option if root= option gets added automatically. You could omit the latter one (until 12/2011 in Ubuntu 11.10), but if the boot drops you to a" busybox initramfs shell" with an error that it cannot find /dev/mapper/cryptroot, this might be the useful.
8. Edit /etc/fstab
You can comment and ask, maybe I forgot some steps that were also needed. Consider also encrypting swap.

1. Boot another system (e.g. Ubuntu from the installation media)
2. Open the new (encrypted) target Ubuntu root filesystem
(cryptsetup luksOpen /dev/vg/new cryptroot)Of course you have not given your volume group a name like "vg" and your logical volume the name "new". (If yes... Do you like that all volume groups on your and your friend's USB drives have the same name "vg"? And do you want to have a logical volume that is old for many years but it is called "new", because you do not want to rename it?)
3. Mount it
4. Mount the /boot partition.(mount /dev/mapper/cryptroot /mnt)
Change the device number accordingly. This is the unencrypted boot partition. Kernel image and initramfs (initrd) boot files are located here.(mount /dev/sda3 /mnt/boot)
5. Chroot to it
6. Install LVM and cryptsetup(chroot /mnt)
Once you install these packages, they will update the initramfs automagically. That is why it is important to have the boot partition mounted.(apt-get install lvm2 cryptsetup)
7. Edit the file /etc/default/grub and add kernel command line options
(GRUB_CMDLINE_LINUX="root=/dev/mapper/cryptroot cryptopts=source=/dev/vg/new")
so that after propagating the changes (update-grub) the generated grub configuration file (/mnt/boot/grub.cfg) has the line

9. Enjoy!(/dev/mapper/cryptroot / ext3 errors=remount-ro 0 1)

Skype does not ring in Ubuntu
Skype does not ring... More precisely, all events that display notifications fail to play sounds, but the others work fine (e.g. testing the event of "Ringing out" plays the sound).
Solution: System -> Preferences -> Sound
Pull up the Alert volume like above.

OpenVAS says 'login failed'
This solution was found at
http://lists.wald.intevation.org/pipermail/openvas-discuss/2008-August/000732.html
"openvas-adduser" probably created the user directory in a different location (e.g. /usr/local/var/lib/openvas/) than the server is looking for it. It needs to moved to /var/lib/openvas.

VirtualBox: Could not find an open hard disk with UUID
My VirtualBox sometimes shows a dialog box that says:
"One or more virtual hard disks, CD/DVD or floppy media are not currently accessible."
My virtual machine becomes inaccessible. Details show this error:
Could not find an open hard disk with UUID {5bad2863-64d0-40a2-a394-7442e3a6adc7}.
Result Code: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)
This happens when a snapshot is removed, then another snapshot is made and the host computer crashes (e.g. freezes during hibernation). After this, there is a reference to a non-existing HardDisk in the configuration file "~/.VirtualBox/VirtualBox.xml". This needs to be updated with the real value. The last working situation can be found in the log file (e.g. "~/.VirtualBox/Machines/<...>/Logs/VBox.log")

Dell Latitude volume keys under Debian
Dell laptops have volume keys above the F-keys. This post explains how to enable them to control the volume.
First, the keys need to be recognized. One can set the right keyboard model in /etc/default/console-setup:
By choosing the right keyboard model, following lines are applied, which should already be present somewhere in /usr/share/X11/xkb/symbols:
First, the keys need to be recognized. One can set the right keyboard model in /etc/default/console-setup:

Firefox displays blank Alert and ssl is disabled
I've got error "ssl_error_ssl_disabled" (Firefox cannot connect securely because the SSL protocol is disabled).
During start, there was always a blank / empty Alert box. That was probably "Could not initialize the browser's security component."
Solution: Moved cert8.db file from another profile (you can also delete it).

cron not running commands
crontab was not working. Silently, not running the command, not writing anything to /var/log/cron. You can check the syntax of your crontab using:
# crontab /etc/crontab "/etc/crontab":16: bad minute errors in crontab file, can't install.
The problem was in splitting command into more lines using backslash \ at the end of each line.
Simple workaround: Put it on one line.
Do not forget also that the minute column is right to the hour column.
