    Getting untruncated command line options passed to a Solaris process

    If you have ever wanted to get the command line options that were passed to a running Solaris process, you might have noticed that the output of command line arguments from ps is truncated to 80 characters. Looking into /usr/include/sys/procfs.h will reveal the reason why! This is because of the restriction in struct psinfo. Here [...]

    Chainloading OpenSolaris from GRUB 2

    I have a triple boot system with OpenSolaris, Ubuntu 9.10 and Microsoft Windows XP. I upgraded my Ubuntu 9.10 GRUB to GRUB 2 today. GRUB2 automatically added an entry for Microsoft Windows XP. However, it didn’t detect the OpenSolaris that was installed. I had to manually configure OpenSolaris chainloading in GRUB 2. If you are [...]

    Enabling virtual consoles in OpenSolaris

    OpenSolaris was lacking virtual console for a while. This support was made available since build snv_124. However, due to various bugs, it is turned off by default. To enable virtual consoles, do the following.

    $ pfexec svcadm enable vtdaemon
    $ pfexec svcadm enable console-login:vt2
    $ pfexec svcadm enable console-login:vt3
    $ pfexec svcadm enable console-login:vt4
    $ pfexec svcadm enable console-login:vt5
    $ pfexec [...]

    Tack sharp eyes

    One of the key things that I try to do when I take portraits is to focus on the eye of the subject. This is a well documented technique and works very well. Also, each lens has a sweet spot aperture for which the picture is really crisp. I find that it is at f/2.8 [...]

    Fix mouse cursor jumping to top left corner of screen on OpenSolaris

    Update 2009-11-07: This issue is fixed in OpenSolaris build snv_126.

    OpenSolaris dev repository update snv_116 introduced an XOrg bug that caused the mouse cursor to jump to the top left corner of the screen very frequently. Apparently, there is some floating point math issue is involved using MMX/SSE2 instructions. I was living with the workaround posted [...]

    Random links for week 36

    My (ex-)manager David Carlton has decided to leave us to join Playdom. I learned a lot in the past two years working with him. We are going to miss him a lot! Playdom is fortunate to have such a talented individual on board. I am sure he will be bringing a multitude of perspectives into [...]

    GNOME Metacity dual screen issue in OpenSolaris 2009.06

    With the latest OpenSolaris 2009.06, maximizing windows managed by Metacity (GNOME) will maximize the windows across both screens. This is due to an issue that Metacity was trying to use a wrong Xinerama type. This issue is fixed in the mercurial repository. However, the fix was not on time to make it into the final [...]

    Setting up FTPS using vsftpd for Wordpress plugins auto upgrade

    One of the handy features in the latest Wordpress is the support to upgrade plugins in one click through the Wordpress administration interface. It needs FTP or FTPS access to the server where you have hosted your Wordpress installation. But turning on FTP for users (non-anonymous) is a bad idea. Using FTP involves transferring user [...]

    Turning off loud system beep in OpenSolaris Gnome and GDM

    Since OpenSolaris started using Gnome 2.24, I started getting loud system beeps those were produced on the PC speaker device that by-passes the audio device. Gnome uses kbd to generate this beep. This beep is so loud that it is really annoying. Also it hurts one’s ears when listening to music using a headset. The [...]
