For me it is much better to use an external mouse than the touchpad, which I sometimes touch accidentally. So, here is how to disable it with a short Perl-Script. A bash script with a bit of Perl would do the same, btw. #!/usr/bin/perl my $tp = `xinput list | egrep -i touch`; chomp $tp; […]
We often encounter situations, where a large number of files should be copied or renamed or moved or something like that. This can be done on the Linux command line, but it should be possible in almost the same way on the Unix/Linux/Cygwin-command line of newer MS-Windows or MacOS-X. Now people routinely do that and […]
It is a common practice in C to use arrays of char as strings. The 0 is used as end marker. The whole thing was created like that in the 1970s and at that time it was kind of cool to get away with one less language feature and to express it in terms of […]
I found this on netzwolf.info: You can enter arbitrary Unicode characters (more precisely code points) in X11 on Linux, if you know their Hex-Code: Press Shift-Ctrl (keep them pressed) Press also the letter u Release the Ctrl-Key Release the u-key Keep the Shift-key pressed Enter the Hex-Code of the Code point with the number of […]
After an upgrade, my Thnderbird started to use a weird US-date format and forgot my setting for this. I did not find any setting either. But this seems to work fine: Create a shell script #!/bin/bash export LC_TIME=sv_SE.utf8 export LC_DATE=sv_SE.utf8 exec /usr/bin/thunderbird and make sure that this gets called when thunderbird is started instead of […]
Deutsch Software often contains a logging functionality. Usually entries one or sometimes multiple lines are appended to a file, written to syslog or to stdout, from where they are redirected into a file. They are telling us something about what the software is doing. Usually we can ignore all of it, but as soon as […]
Typically we observe that line endings of text file turn out to be „linefeed“ (LF or „\n“ or 0x0a or Ctrl-J) on Linux and Unix-like systems (including MacOSX), while they are „carriage return and linefeed“ (CR LF or „\r\n“ or 0x0d 0x0a or Ctrl-M Ctrl-J) on MS-Windows. See the little obstacles of interoperability. This can […]
Deutsch A lot of things in today’s IT landscape have been unified and interoperability is much better than 20 years ago. Some examples: Networking: Today networking is TCP/IP. Even the physical cables with RJ45/Ethernet and the wireless networks have been standardized and all kinds of devices can use the same networks. In the old days […]
Today we should use encryption of disks for many situations. I recommend at least encrypting disks of portable computers that contain the home directory and portable USB disks. They can easily get stolen or lost and it is better if the thief does not have easy access to the content. We should even consider encrypting […]
It seems that Microsoft is ending the development of Windows Mobile. After having tried with some effort to get into the mobile operating system business, it seems that the market share is now less than 1%, with Android being >85% and iOS close to 15% according to IDC. Because the market is so large, it […]
