As we all know, under windows we can flush the DNS cache with
ipconfig /flushdns
But what is the linux equivalent command? It is so obvious, yet I somehow keep forgetting it. 🙂
Under linux, the standard way to have a daemon reload its configuration, is sending a SIGHUP signal. In case of the name service cache daemon (nscd), this implies flushing its cache!
So you could use the following command to flush the DNS cache if you’re using nscd:
pkill -1 nscd
When you live in Belgium, being ripped off for broadband internet and telephony is your inevitable fate. It’s like there is some conspiracy to keep Belgian people away from the information highway. However, it seems after decade(s) of suppression, there is a little light at the end of the tunnel. 🙂 This month brings interesting news, especially if you’re a Telenet customer.
First of all, my data limit gets doubled next month and even tripled in July. Second, they finally got rid of the silly mail box size (50MB), although the silly web space without php/mysql stays. 😉
Third, and that’s why I started this post actually, is the possibility to program your digicorder (digital PVR) from wherever you are using a website (Dutch announcement)! I’ve always wanted that. 🙂 I won’t go into details why the digicorder still sucks big time (and once more, Java and “slow” seem to go together, painful coincidence? ;)), still, I welcome any improvement. 🙂 Way to go Telenet!
Nowadays, we live in a KDE4 world for real, so it’s time to update my “dump audio from video file” service menu 😉 It should work both in Konqueror and Dolphin.
Create a file with the following contents and put it in one of your service directories (which you can find out by running “kde4-config –path services” , typically you will have something like $HOME/.kde4/share/kde4/services )
[Desktop Entry]
Type=Service
Encoding=UTF-8
ServiceTypes=KonqPopupMenu/Plugin,video/*
Actions=extractaudio
[Desktop Action extractaudio]
Name=Extract audio
Name[en-GB]=Extract audio
Exec=mplayer -dumpaudio %u -dumpfile %u.dump
Icon=speaker
Recently, I watched a vid about Apple’s Time Machine and was quite impressed. For the first time in ages, I was considering to try out MacosX, after all, you have to give them credit: they just keep innovating as no other computer company. The plan was quickly abandoned though, when I discovered it wouldn’t run on my newly bought AMD monster-machine (post about that in queue ;)).
Anyhow, I searched some alternatives and somehow nothing as user-friendly showed up.. Until today I stumbled upon the solution by accident while I was checking out LinuxJournal’s tech tips! Quite interesting/entertaining stuff there btw. 🙂 I’m talking about about Back In Time and considering the Ubuntu dev, it even has a KDE4 gui, yay! 🙂
Check out the LJ screencast and the LifeHacker article.
I was trying to watch a vid on a website which was quicktime only. Since I’ve had some trouble a few days ago to play a wmv file on a windows media only site, I decided to give the firefox mplayer plugin a try. I had heard of it before but never found a compelling reason to install it. Until now. It just plays _everything_! I can’t believe how I could live so long without it. 🙂 Or maybe because 99% of the web’s vids are flash? 😉 (which works, of course)
Here is the supported formats list:
Window Media: wmv, avi, asf, wav and asx
QuickTime: mov and smil
MPEG Video and Audio: mpeg and mp3
Ogg Vorbis: ogg
AutoDesk FLI: fli and flc
Vivo: vivo
Real Player: ram and rm
I just discovered I had a mail in my outbox I sent last week. It turned out one of my email accounts was not properly migrated from Opera 9.
I ran Wireshark and it seemed Opera was sending a wrong parameter with the EHLO command (which queries an ESMTP server for its capabilities). It sent EHLO smtpserver instead of EHLO myhostname. Of course the server replied this could not be the case since he was that host himself. =)
So I grepped the accounts.ini file to see where that information could come from. It turned out there was a fqdn property present containing the smtp server name which was not present anymore in a newly created account (yet it seemed to attach some value to it, apparently). So I simply deleted the fqdn property and all was solved. 🙂
Keep in mind, I am upgrading the same opera profile since Opera 7 so I guess my particular upgrade scenario has received less attention. 😉
You’re at work and want to access your git repo who’s residing in the free external world?
create the following config file in your .ssh folder:
Host
ProxyCommand connect -S <proxy host>:<proxy port> %h %p
replace the hosts and port as appropriate.
You can find the connect executable for windows here (contains a lot of other useful socks info as well).
Hat tip to pieter.
I discovered just recently that finally, since java 6, you can actually use wildcards in your classpath to include all jars in a dir! This also works in jar manifests!
why does it have to take so long? 😉
I used to take over a running terminal session on a server using the console command line parameter. It seems this is deprecated now. I didn’t read the whole story, bottom line is, you could try the /admin option instead. 🙂
