The problem only occurred if you use Internet Explorer 6 or older. Using href=”javascript:;” and onclick=”some function” will ignore onclick in IE6 (does not happen w/ Firefox). Solution: simply use “javascript:some function;”

Delete small files less than 100Kbytes: “find -size -100k | xargs rm” or find -size -100k -exec rm “{}” “;”

If you get this error that device is not supported by running the default command
<br /> [root@s4 downloads]# smartctl -a /dev/sda<br /> smartctl version 5.33 [i686-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen<br /> Home page is http://smartmontools.sourceforge.net/</p> <p>Device: ATA WDC WD800JD-60LS Version: 07.0<br /> Serial number: WD-WMAM9F764913<br /> Device type: disk<br /> Local Time is: Tue May 15 13:12:49 2007 CDT<br /> Device does not support SMART<br /> Request Sense failed, [Input/output error]</p> <p>Error Counter logging not supported</p> <p>Error Events logging not supported</p> <p>[GLTSD (Global Logging Target Save Disable) set.

It’s pretty interesting to see that Alexa is using CSS to scramble site traffic results. Now you cannot select, copy the data and paste into somewhere else because some random numbers are added between the original characters.

The browser sees this:

<br /> adspeed.com – 96%<br /> serv.adspeed.com – 4%<br />

The code is actually this (if CSS is disabled)

<br /> 2a80dspeed.co644m – 9196%<br /> 70serv.adsp1931eed.88com – 434%<br />

I have not had time to dig deeper into this and it’s just an interesting observation.
