underdevelopment

You hate reading? you want to try out mod_pagespeed? you run a ubuntu or other debian based server? Well then just follow the following steps.

1. get the binary package based on your architecture. (to check which one run “uname -m”. If it says x86_64, they you have a 64bit server)
   • 64 bit.

     wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-beta_current_amd64.deb

   • 32 bit.

     wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-beta_current_i386.deb

2. install the package (substitute am64.deb with i386.deb if you don’t have a 64bit version)

   sudo dpkg -i mod-pagespeed-beta_current_amd64.deb

3. open up the following file with your favorite editor

   /etc/apache2/mods-available/pagespeed.conf

4. add all the cool features you want, i currently run this. (line 47 in the file, but it doesn’t really matter)

   ModPagespeedEnableFilters collapse_whitespace,elide_attributes
   ModPagespeedEnableFilters combine_css,rewrite_css,move_css_to_head,inline_css
   ModPagespeedEnableFilters rewrite_javascript,inline_javascript
   ModPagespeedEnableFilters rewrite_images,insert_img_dimensions
   ModPagespeedEnableFilters extend_cache
   ModPagespeedEnableFilters remove_quotes,remove_comments

5. restart apache

   sudo service apache2 restart

6. done.

I haven’t fully looked into mod_pagespeed and all its filters and implications there of myself, but I always like following these kinds of lazy quick guides myself to start poking around instead of actually reading something for a change. So i figured I should just make one as well.

I recently purchased a sony vaio VGN-BZ31VT. To be short, everything works for as far as I know and care.

Specs

CPU: Intel® Core™2 Duo-processor P8700 @ 2,53 Ghz
mem: DDR2 SDRAM (2 x 2 GB)
graphics: Mobile Intel® Graphics Media Accelerator 4500MHD

Wifi: intel wifi link 5100
audio: intel HD audio
ethernet: Intel 82567 Gigabit
bluetooth: ?  2.0 + EDR

what works

Well all the basics seem to work, the special function keys on the keyboard, the mouse pad, the screen, wifi and ethernet port.
But most importantly, suspend and hibernate also work. All of this out of the box, just install and go.

incidentally, this CPU also support intel VT, it is off by default, but you can easily enable it in the bios. If like me you use virtual machines a lot, it is rather nice to have. Haven’t done any real tests to see if it is faster, but at least it’s there.

Not tested

I haven’t tested bluetooth, don’t need it.

What doesn’t work

The laptop also has a fingerprint scanner, which with some tinkering can be used. It’s not so much a problem of hardware support it seems, but more that there isn’t a mainstream way of integrating fingerprints scanners with the security system in linux. The solution I read needs you to install some fingerprint scanning software and load that as a module in PAM. Too much work for too little gain for my taste, but if you really want it, then you can get it to work (probably).

conclusion

I wanted a no-nonsense development laptop with lots of memory and preferably virtualization support in the CPU, it should also work under linux with minimal fuss and suspend working was a must have.
Mission successful it seems.

Seeing as there is very little recent user experience info about this laptop out there at the moment, i figured i should write this little blog, if only to give people the peace of mind that you can safely buy this laptop for running linux.
