On Kubuntu 14.04, Kinetis Design Studio (KDS) could be started, but when I tried to create a new project, it’d crash with the following message displayed in the terminal: $ kinetis-design-studio java: /build/buildd/gtk2-engines-oxygen-1.4.5/src/animations/oxygencomboboxdata.cpp:87: void Oxygen::ComboBoxData::setButton(GtkWidget*): Assertion `!_button._widget' failed. KDS is a Eclipse-based IDE. So I suspect the issue is related to Eclipse IDE itself. (I can’t confirm this as I’m not running the Eclipse IDE on this machine. I know I could have just downloaded and test it; but I don’t have time.) ...

For Linux users who want to update Kinetis Design Studio (DKS), if you launch KDS as a non-privileged user, you’d have to relaunch KDS with sudo for update to go ahead. $ sudo /opt/Freescale/KDS_3.0.0/eclipse/kinetis-design-studio Then to update it, just click on Help -> Check for Updates from the menu.

I just noticed that in the /root directory, there exists a directory with its name starting with a dash: -p in my FreeBSD box. root@raspbsd:~ # ls -l total 144 drwxr-xr-x 2 root wheel 512 May 5 18:26 -p drwxr-xr-x 2 root wheel 512 May 5 20:45 .byobu drwxr-xr-x 3 root wheel 512 May 5 20:45 .cache -rw-r--r-- 2 root wheel 959 Jan 23 00:59 .cshrc As much as I wanted to get rid of it, I was curious to find out what’s inside that directory. ...

Someone asked this question in one of his blog posts: Ever see this? dhcpd: uid lease 192.168.1.150 for client xx:xx:xx:xx:xx:xx is duplicate on 192.168.1/24 Yes, I’m seeing something like that now in the my dhdcp logs. Here is the actual message: DHCPREQUEST for 192.168.1.109 from 08:00:27:6e:61:b8 via eth0 DHCPACK on 192.168.1.109 to 08:00:27:6e:61:b8 via eth0 DHCPINFORM from 192.168.1.109 via eth0 DHCPACK to 192.168.1.109 (08:00:27:6e:61:b8) via eth0 uid lease 192.168.1.224 for client 08:00:27:6e:61:b8 is duplicate on 192.168.1.0/24 DHCPREQUEST for 192.168.1.109 from 08:00:27:6e:61:b8 via eth0 DHCPACK on 192.168.1.109 to 08:00:27:6e:61:b8 via eth0 I think I know why this happened.
