HTTP Compression on Redhat / CentOS / Fedora
I was doing some testing on my server the other day, and realised that http compression within apache (httpd) was not enabled by default. Further digging showed me that mod_defate was what I needed, and infact it was installed by default on my CentOS box.
How to enable mod_default on Centos: Create /etc/httpd/conf.d/deflate.conf with the following contents
# Insert filter
SetOutputFilter DEFLATE
# Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html
# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4.0[678] no-gzip
# MSIE masquerades as Netscape, but it is fine
BrowserMatch bMSIE !no-gzip !gzip-only-text/html
# Don't compress images
SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
# Don't compress already compressed stuff !
SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .pdf$ no-gzip dont-vary
# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
# Log Stuff !
# DeflateFilterNote Input input_info
# DeflateFilterNote Output output_info
# DeflateFilterNote Ratio ratio_info
# LogFormat '"%r" %{output_info}n/%{input_info}n (%{ratio_info}n%%)' deflate
# CustomLog /var/log/httpd/deflate_log deflate
restart httpd (/etc/init.d/httpd restart) and your done

n800 bookmarks
For those who are looking for n800 resources, last night I published all of my n800 bookmarks – http://del.icio.us/linickx/n800
They will eventually be pushed here with my other del.icio.us bookmarks but due to the recent vulnerability in xmlrpc I’ve disabled the access.
Being an n800 owner is expensive.
I’ve had my n800 a couple of weeks now, and I’m still in the “lovin it!” phase; but one of the things I’ve quickly noticed is that being an n800 owner is quickly going to become an expensive affair.
I’m a novice PDA person, in fact this is the first one I’ve brought, previous companies have leant me smart-phone PDA’s so actually buying one was a big commitment to me… we all know that computer technology, especially gadgets have a limited lifespan.
To ensure I get the most out of my n800, I insisted on buying the Navicore “sat nav” upgrade, my reasoning being that if n800’s basic functionality doesn’t meet my needs that sat nav functionality will be invaluable… I’m always getting lost!! This decision was in it’s self an expensive move; the n800 is £280… ok not bad for such a feature rich pda, but the navicore pack is £150, half the price again!
In the time I’ve had n800 the navicore software has been great, it’s got me door to door when I don’t know where I’m going, and when I do just having it on and “beeping” when I’m near a traffic camera is a real bonus for me, but in my day to day use of n800 I’m wondering if I could have spent the money better else where?
To start with the case that come in the n800 pack, is a flimsy felt thing, ok so it’ll protect the screen from the odd scratch, but other than that I’ve got to be careful that it doesn’t [a] fall out my pocket or [b] have something sharp (like a parker pen) “poke it”. It looks like a leather case is about £35 and a screen protector would also be a good idea, that’d be another £6, I guess in relation to what I’ve already paid out that doesn’t seem like a lot (well excluding postage).
The expense really starts to stock up when you look at the usability, you get a 120Mb Mini-SD card, which is enough to store a little music (I have two cds) and a short video (I have 30mins), this is not exactly a library of entertainment to choose from if you have to hop on a train for an hour where an internet connection is non-existent; it appears that memory hard range from a modest £10 (512mb) to £50 (8Gb) considering there are two slots and you can’t yet run n800 as a usb host to connect a usb disk to, what you spend here really is dependent on how often you are “removed” from the net. A final area to look at on my radar would be the usability, I’m typing this on my laptop, I could use my n800 but trying to use the handwriting thing or the touch keyboard is so slow it’s frustrating, so I’m looking at a bluetooth keyboard but look they’re another £75.
Of course there are other bits and pieces you might need, like chargers or spare batteries so, if you’re looking to buy an n800, be prepared. As you can see I only budgeted for n800 + navicore and I feel now that I should have thought further; that said, I’m still happy, and the other stuff will just have to be brought in good time, just make sure you buy the right accessory’s for you !
Disclaimer: The n800 is an Internet Tablet, not a PDA, but I don’t buy that marketing B*&$£!”£%
What’s happened to the linux counter?
I’ve been a proud linux counter member (#372709) for sometime now; a few days ago I got some bounce-back error messages..
<machine-registration@gimel.counter.li.org> (expanded from <machine-registration@counter.li.org>): delivery temporarily suspended: connect to gimel.counter.li.org[158.38.152.227]: No route to host</machine-registration@counter.li.org></machine-registration@gimel.counter.li.org>
I didn’t think, much of it at the time, maintenance happens, but today noticed it again, a quick google shows that others have noticed too… I do hope this isn’t the end of what was a great project 
Extra Packages for Enterprise Linux… CentOS !
Why has it taken me so long to spot this ? Looks like this draft was written on the 13th May, if I hadn’t have been just about to download FC7 then I’d have missed it !
EPEL – Fedora Project Wiki
EPEL is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages that complement the Fedora-based Red Hat Enterprise Linux (RHEL) and its compatible spinoffs like CentOS or Scientific Linux.
About time, and thank you redhat/fedora, want fedora extra packages in centos, then install this epel-release .rpm frickin’ sweet !
