Speeding up Liferea

Anthony Batchelor — Fri, 21 Aug 2009 13:46:38 +0000

Liferea was taking a couple of minutes to open for me, so I thought I’d look for a solution to that. I have >100 feeds, but I’m not about to cut the amount down (not addicted, honest).

Liferea stores a lot of information in an sqlite database. If sqlite databases aren’t vacuumed every now and then, they bloat and slow down.

Most people know about speeding up Firefox by vacuuming the sqlite databases every now and then. Well, the same can be done with Liferea.
Close Liferea and paste the following in a bash terminal.

sqlite3 ~/.liferea_1.4/liferea.db "VACUUM;"

Open up Liferea and you should notice it load much faster. Unless of course, it was fast to begin with.

Handy Hints: What is using up my disk space?

Anthony Batchelor — Mon, 06 Apr 2009 12:59:36 +0000

Here are some commands I use to find out what is eating all of my disk space on a remote server:

df -h Shows how much disk space is available. The -h means that you get G for gigabytes, M for megabytes etc.

sudo du -k / | sort -n Shows which directories are biggest (starting at the root directory /). The biggest ones will be printed at the bottom of the list. The sudo allows du to check directories that your user doesn’t have permission for. To check your home directory only use du -k ~ | sort -n

du -ka | sort -n Shows the size of all the files and sub-directories of the current directory. The biggest ones at the bottom of the list.

watch 'du -ka | sort -nr' Shows the size of all the files and sub-directories of the current directory. The biggest ones at the top of the list. The list is updated every 2 seconds. This is useful for watching disk usage in a particular directory, such as an upload directory on a web server.
