I just tried out a build from the Subversion 1.7.x branch which appears to come close to a final release. Instead of creating
.svn directories everywhere, the new working copy layout switches to a central storage using SQLite. You will only see a single
.svn at the top most directory of the working copy. Details are outlined in the preliminary release notes.
After the upgrade to Linux kernel 2.6.38, the boot process for my machine hang quite long while
Populating /dev with existing devices through uevents. After investigations it turns out that the
cx88 driver used for my Hauppauge WinTV HVR-1300 tv card was not correctly converted to the new mutex system while removing the BKL. This is being tracked in the kernel bugzilla as bug #31962.
Fortunately, there is a patch attached to the mentioned bug report which resolves the problem:
wget -O cx88-2.6.38-fix-driver-deadlocks.patch 'https://bugzilla.kernel.org/attachment.cgi?id=53722'
patch -p1 < cx88-2.6.38-fix-driver-deadlocks.patch
[Edited on 2011-04-23: replaced patch 52902 with 53722]
After applying the patch, build and install your kernel as usual. But there are still some more problems with 2.6.38 related to tvtime. See also my next post.
I do not follow kernel development close enough to know in which git tree this has to show up to confirm if it has been merged yet. Hopefully this patch will make it into the next kernel release.
Reuse the last argument of the previous command with
$ echo abc def
$ echo !$
A common use case would be
$ mkdir foo
$ cd !$
You can also insert the last argument of the previous command and continue typing with
$ echo abc def
$ echo <ESC>. ghi
Oh, the little things… 🙂
Once again I missed the expiry date of one of the SSL certificates on my server. Therefore I am now using a cronjob to warn me early enough that a certificate is about to expire.
This is the script
/usr/local/bin/ssl-cert-check which checks the expiry date of the certificate files passed as arguments:
for file in "$@"; do
openssl x509 -checkend $(( 86400 * $DAYS )) -in "$file" > /dev/null
if [ $? != 0 ]; then
echo "==> Certificate $file is about to expire soon:"
openssl x509 -enddate -in "$file" -noout
And the corresponding cronjob entry checking SSL certificates once a day:
6 6 * * * nobody /usr/local/bin/ssl-cert-check /etc/apache2/ssl/*.crt /etc/ssl/certs/dovecot.pem
What is this?
I prefer IRC as communication protocol for multi-user chat and instant messaging. To keep in contact with users of other protocols/clients I use BitlBee which is a gateway connecting other chat networks like Jabber/XMPP and ICQ to your own IRC server.
