In the previous post I wrote about enabling compression for your pages so that they would load faster to the visitor. Today I’m going to write about how you can make use of browser caching to save some bandwidth. Some people told me that their ISP or hosting provider requested that they upgrade the hosting [...]

In 2008, I wrote Compressing WordPress Output and this is done by adding one line to index.php The problem with that approach is that when you upgrade WordPress you have to manually add the line into index.php, and the [...]

I’ve been pushing the limits of my mid-2010 13″ MacBook Pro lately, running all sort of applications and leaving them running. There has been occasions where the machine will freeze while it struggles to schedule the CPU time to all of the applications. I use a lot of email, and by a lot I don’t [...]

I was looking for a simple utility that will work like dos2unix tool on Linux to convert endlines from DOS to UNIX. I was scraping some contents from a server running .NET and those ugly ^M characters appeared in vim. I found this https://ccrma.stanford.edu/~craig/utility/flip/, downloaded the PPC binary and used it happily for a while. [...]

On my MacBook Pro with minimal disk size (250GB) I had to install VirtualBox in order to run any kind of Windows, for emergency cases. I was able to install Windows Server 2008 in a 20GB dynamically expanding virtual disk image (VDI). A couple of months back I also made a clone of my HP [...]

I have just received an email from Yahoo! announcing the end of MyBlogLog service. It’s going to be discontinued effective May 24, 2011. Nice of Yahoo! to give us some time before terminating it for good.

This is related to the previous post, where I had a lot of checked out Subversion working copies in my disk. They came from a Windows machine I used before I bought myself a Mac. For your information, in a Subversion working copy, there will always be a hidden folder named .svn in each directory, [...]

Since I moved to a new home I didn’t let my Linux servers run 24/7 so that I can save on electricity bills. It’s not so much about moving homes but it’s about the tariff increase. My 500W and 400W power supplies can easily reach the max usage of around 300W each which translates to [...]

I saw quite a significant number of tweets mentioning Google Instant, and decided to check it out. Some people might already be aware of it or heard of it before but I am outdated, that I am willing to admit. First, I went to the Official Google Blog where I saw Search: now faster than [...]

I had to transfer 2 WordPress blogs to another hosting provider last night, as the free one is going to expire today.

PHP does not have any SMTP authentication mechanism in its configuration, and most developer opt for PEAR packages to perform email sending via custom ports and SMTP authentication. I am one of those who will avoid using external packages as much as possible unless really necessary, and of course because I wanted a quick solution [...]

If you’re one of the SysAdmins working for Maxis, and you celebrated the recent System Administrator’s Appreciation day, you should really think about your future. SysAdmins are supposed to make people life’s easier, not the other way round. Maxis has been implementing transparent proxy for some time now, I think to save on bandwidth usage [...]

I wanted to be able to use my personal laptop to check my work email, so that I don’t have to carry around the 3kg DELL beast all the time. Sure, I can use the Blackberry but typing long emails on it can prove painful especially with fat fingers. I have VPN access, but Cisco [...]

While attempting to compile djbdns 1.05 and daemontools 0.76 on a CentOS 5.5 I received the error: /usr/bin/ld: errno: TLS definition in /lib/libc.so.6 section .tbss mismatches non-TLS reference in envdir.o The problem can be eliminated by adding: -include /usr/include/errno.h In conf-cc files for each tarball.
