Midnight Commander is a convenient two-panel file manager with tons of features.

You can create hard links and symbolic links using C-x l and C-x s keyboard shortcuts. However, these two shortcuts invoke two completely different dialogs.

While for C-x s you get 2 pre-populated fields (path to the existing file, and path to the link – which is pre-populated with your opposite file panel path plus the name of the file under cursor; simply try it to see what I mean), for C-x l you only get 1 empty field: path of the hard link to create for a file under cursor. Symlink’s behaviour would be much more convenient…

Fortunately, a good man called Wiseman1024 created a feature request in the MC’s bug tracker 6 years ago. Not only had he done so, but he had also uploaded a sample mc user menu script (local copy), which works wonderfully! You can select multiple files, then F2 l (lower-case L), and hard-links to your selected files (or a file under cursor) will be created in the opposite file panel. Great, thank you Wiseman1024!

Word of warning: you must know what hard links are and what their limitations are before using this menu script. You also must check and understand the user menu code before adding it to your mc (by F9 C m u, and then pasting the script from the file).

Word of hope: 4 years ago Wiseman’s feature request was assigned to Future Releases version, so a more convenient C-x l will (sooner or later) become the part of mc. Hopefully.

• sysv-rc-conf: text-UI, allows editing multiple runlevels, but seems to be failing recently
• rcconf: another good-looking text-UI alternative; can only modify current runlevel
• bum: GUI tool (BootUp Manager)

More details about these tools and runlevels (in German).

I have recently realized that my planning habits are quite similar to what The Secret Weapon promotes. However, my planning is not as elaborate and detailed/structured as TSW, and I am using several tools:

• Google Keep, an awesome note-taking and to-do lists application with a really good web-interface, and free;
• Trello, convenient lists/projects/tasks management platform (especially for group work), and free;
• Google Calendar, the de facto calendar standard for Android phones, and free;
• my A5 format weekly paper planner, and… the only not free component.

It is easy to see that I am using too many tools.

In an effort to use less tools, and also to try some of the features of TSW, I’ve performed a brief search for GTD/TSW-compatible Android apps.

TSW website is built around the Evernote app. However, I am not sure if this would be a good solution for me, as I have been already using Evernote since several years for longer-term note-keeping, and thus already have a bunch of notepads, notes, and tags there. Moreover, Evernote’s website mentions something about “offline notes” in the Premium (non-free) tier for mobile apps; this hints at the requirement to have internet connectivity to be able to work with TSW+Evernote efficiently through the day.

Oh, before I forget: all the 4 tools that I am using have their purpose, with overlap between Keep and Trello.
My A5 format paper planner (weekview compact 2015) is not a simple weekly planner; it has a structure that stimulates goal-oriented planning.
More specifically, it provides means to plan:

After fixing offline uncorrectable sector warning email, I have taken a closer look at my /etc/smartd.conf, and now it looks like this:

DEFAULT -d sat -H -f -p -t -W 0,40,45 -n standby -S on -m example@example.com
# Attributes 1, 230, and 231 are very important (-r 1! -r 230! -R 230! -r 231! -R 231!), but likely covered by -t.
/dev/sda -s (S/../../6/01|L/../(01|02|03|04|05|06|07)/7/00) -C 0 -I 189 -I 194
# -a implies -f and -p (through -t)
DEFAULT -d sat -a -I 194 -W 0,40,45 -n standby -o on -S on -m example@example.com
/dev/sdb -s (S/../../6/02|L/../(01|02|03|04|05|06|07)/7/02)
# This drive does not decrement Offline_Uncorrectable (198) after re-allocation,
# so only monitoring for increase, not for non-zero value.
/dev/sdc -s (S/../../6/03|L/../(01|02|03|04|05|06|07)/7/04) -U 198+
# This drive has 40 “normally”.
/dev/sdd -s (S/../../6/04|L/../(01|02|03|04|05|06|07)/7/06) -W 0,42,45

Note: explanations below are intentionally simplified; please consult man smartd.conf for more precise, complete, and up-to-date information.

Ok, so what do these settings mean, and how is this different from default settings?

There are quite a lot of posts on how to do this, but my differs a tiny little bit, so I’m saving it for my own future reference, and also for the benefits of the wider audience.

I am updating a multisite Drupal 6 installation. To the best of my knowledge, the only difference for Drupal 7 is that instead of the site_offline D6 variable the maintenance_mode variable is used in D7.

On Debian stable and later, you can sudo aptitude install drush and then just use it immediately after that.

Note: I recommend su webuser (or sudo -s followed by sudo -s -u webuser) before you run any non-testing drush commands, where webuser is the user which owns your web-exposed files (e.g. Debian’s default is, I think, www-data). I’ve seen a lot of recommendations to run drush as a super-user, but that does not make sense, and may actually cause problems with file ownership.

One last thing before we start: if your drush seems to work fine but hangs when untarring modules – check this solution.

Drush is awesome, especially for updating multisite Drupal installations.
I had only started using it a few days ago, and I’ve immediately hit a problem, to which I did find a workaround.

Symptoms

• running drush @sites pm-update results in normal execution up to after answering ‘y[es]‘; then drush seems to hang indefinitely (haven’t waited beyond about 10 minutes, maybe it does produce an error after a long while);
• running the same command with --debug shows that drush hangs when trying to untar the downloaded module.tar.gz archive; there are no errors/warnings, it just hangs with no CPU usage;
• trying to untar any of the modules downloaded from drupal.org manually is also unsuccessful: tar -xzvf module.tar.gz seems to do nothing, it also hangs with zero CPU usage/time and no warnings/errors;
• interestingly, if I create some test.tar.gz locally, tar does happily extract that;
• finally, running strace tar -xzvf module.tar.gz shows a number of unexpected lines, such as references to NSS and libnss files (I am only showing some of the lines of strace output, including the last line):
  

  open(“/etc/nsswitch.conf”, O_RDONLY) = 4
  read(4, “# /etc/nsswitch.conf\n#\n# Example”…, 4096) = 683
  open(“/lib/x86_64-linux-gnu/libnss_nis.so.2″, O_RDONLY) = 4
  open(“/lib/x86_64-linux-gnu/libnss_files.so.2″, O_RDONLY) = 4
  open(“/etc/passwd”, O_RDONLY|O_CLOEXEC) = 4
  open(“/usr/lib/x86_64-linux-gnu/libnss_mysql.so.2″, O_RDONLY) = 4
  open(“/etc/group”, O_RDONLY|O_CLOEXEC) = 4
  open(“/etc/libnss-mysql.cfg”, O_RDONLY) = -1 EACCES (Permission denied)
  open(“/etc/libnss-mysql-root.cfg”, O_RDONLY) = -1 EACCES (Permission denied)

If you try starting Outlook 2010 and get an error like this:
“Outlook 2010 cannot open your default e-mail folders. An unexpected error has occurred. MAPI was unable to load the information service gwmsp1.dll”

you can easily fix this problem by going to Control Panel, clicking on Mail, then Show Profiles button.
Remove everything that’s there. Now start outlook again.

Note: removing all the mail profiles will disable your Novell Groupwise client.
If you still want to use non-Outlook email profiles, then the better solution is to manually create a new mail profile for Outlook.
