Filtering messages in rsyslog

Each time I open a new chromium-browser tab, I get messages like this in /var/log/syslog:


May  6 09:15:37 compiler kernel: [4742643.809674] type=1701 audit(1367824537.257:40179): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=433 comm="chromium-browse" reason="seccomp" sig=0 syscall=2 compat=0 ip=0x7f3de13f86c0 code=0x50002


This kind of continuous log writing is annoying and useless in my "desktop" system, even worse with an SSD disk, so I started looking how to filter rsyslog messages based in text strings.

Thanks to Javier Vela, I finally added the following to my /etc/rsyslog.d/50-default.conf:



#### Begin - Remove chromium-browser messages:

if      ($syslogfacility-text == 'kern') and \
        ( \
              ($msg contains 'chromium-browse') or \
              ($msg contains 'Chrome_') or \
              ($msg contains 'callbacks suppressed') \
        ) \
       then    ~

#### End 

auth,authpriv.*                 /var/log/auth.log
-/var/log/syslog
*.*;auth,authpriv.none          -/var/log/syslog
kern.*  -/var/log/kern.log
mail.*                          -/var/log/mail.log



After an service rsyslog restart or /etc/init.d/rsyslog restart , the message will not appear again.

Autoreload external code changes in Eclipse

Interesante, para poder usar "git" manualmente en Eclipse sin el plugin de Egit:

I have started using Sublime text as my preferred code editor (for JS, CSS, Coffee). But, I still rely on Eclipse for writing Java code because it auto-imports Java packages and auto suggests variables and method names from my custom class files.

Working on multiple editors throws in another problem: whenever I make a change in some file outside of Eclipse, the IDE does not silently reload. It shows a blank page saying 'The resource is out of sync. Press F5 to reload'. The message started annoying me soon as I had to switch back and forth often.

It is not just for the multiple editors. Even when I do a git pull, the resources go out of sync.

Then, I found a workaround for this. Eclipse provides a built-in option that auto reloads a resource if its out f sync. Here's how you  can enable it.

Go to Window -> Preferences -> General -> Workspace  and check the option 'Refresh using native hooks or polling'.

So, the next time when you try to open a out of sync file, the IDE will sync it for you (thus saving you a keystroke, one at a time  ).

El autor del mensaje original no lo comenta, pero también es necesario activar la opción Refresh on Access.
