I got confused: should I use insserv or chkconfig on SLES? How do they differ?
Apparently, chkconfig is a perl wrapper to insserv, which actually mimics chkconfig very well.
Good.
SuSE chkconfig vs. insserv
June 29th, 2009Windows firewall adventures
June 20th, 2009At work, I needed to block outgoing IP connections in order to inspect the behavior of our product.
I thought: why not use the native, Windows Firewall for that? Oh. Controlling outgoing connections is not supported by windows firewall (w2k3, at least). lame.
So I went on and searched the net for free windows firewalls. And.. I couldn’t find anything good which is really free. So I’ve started looking for less-free firewalls, and found the Kerio firewall which is a trial version which expires if you don’t pay them $$s.
It was pretty good actually, and satisfied my needs.
[30 days later]
Why is this VM so slow?? Remote desktop doesn’t work.. After chasing the wrong error message problem, I’ve tried logging in through the vmware console. Then I’ve noticed this little balloon on the systray saying something like “Kerio firewall trial has expired; limiting bandwidth to 4kb/sec“. OHHH that’s just a great attitude!
Local issues
April 30th, 2009This is not a post of original content, I’m simply linking to interesting things I’ve read recently.
- Israel: Linux-IL mailing list is inspecting some weird phenomenon. Looks like 012 ISP is blocking SSH packets which are sent abroad.
- Hebrew: this feature is too hidden.. Diego explains that how to enable left/right alignment switching by ctrl+shift. (Useful for RTL languages). The “trick” works for QT, KDE (3+4) apps.
Weird CSS tricks
April 22nd, 2009I was quite surprised to find out these two interesting css “tricks”:
- Data urls: putting the data inside the CSS (inline).
- CSS sprites: instead of loading many small images (one per item), it’s possible to load one big image that contains them all.. then play with the offsets to get the right image.
פוסט ליום השואה: בירקנאו
April 21st, 2009
Auschwitz Birkenau. click to enlarge the photo.
את התמונה הזו צילמתי במסעי לפולין מביה”ס התיכון.
זוהי תמונה של מבני המגורים (מילה עדינה מדי בשביל לתאר את תת התנאים ששררו שם) של מחנה אושוויץ-בירקנאו. זהו מחנה עצום מימדים עם עשרות מבנים מאוד ארוכים, שהיה למעשה מחנה ההשמדה בו הושמד מספר האנשים הגדול ביותר (מעל מיליון).
מבחינתי זהו מקום שמסמל את הרמה השפלה ביותר אליה האדם הגיע.
For the dear English readers: today is Holocaust memorial day in Israel. I’ve taken this photo in my journey to Poland on year 2000. This is the picture of the barracks of Auschwitz Birkenau, the extermination camp in which the highest number of people were executed: over a million. In my opinion, this place represents the lowest point that human beings have ever reached.
