CentOS 4.8 in Virtualbox 5.1.x



Years ago I was part of a project that was developed on and ran on CentOS 4.8. The software we developed was only used in-house so we were able to work around any bugs we found. The development cycle was extremely short, 4 months, considering the end result.

While we've backed up the source frequently over the years the software really never got a major facelift. I spent a bit of time over the years making some minor changes (I gave the menu a facelift changing it from rotating gifs to CSS, and made some code changes to deal with a tax shift that happened years ago), but what the project really needs is a major overhaul.

One of my goals right from the outset was to open source the project, but this didn't happen because I was simply too swamped with other things to completely audit the code. Also I wanted to simplify the project before exposing it to the world. Initially we based the project on an eCommerce suite (OSCommerce). At the time we were using that suite for another project and we thought we'd just export the database to another live site based on the same eCommerce suite. That never happened and the eCommerce suite added many more tables and fields we never ended up using (though we added a few of our own).

This all brings me back to the fact that the project was running on CentOS 4.8, an old version of CentOS (which has been on version 7 for awhile). I struggled getting CentOS 4.8 to install in Virtualbox 5.1.x, mostly because I was trying too hard. CentOS would start to boot then hang with an NMI error. The problem was that I was trying to install using the Linux kernel 2.6/3 as a base when what I really needed to do was just select Red Hat 64 (the default). I was overthinking the installation. When I finally tried the default selection for Virtualbox CentOS 4.8 installed just fine.

Converting an 82 year old to Xubuntu GNU/Linux

A few weeks ago Irvin (not his real name) came into our computer recycling project. Irvin is 82 years old. He walks with a walker and somehow managed to lug a fairly big desktop Lenovo Thinkcentre down to our recycling project. Irvin had been to several computer stores over the past few months trying to get help with his computer. Unfortunately it seems that he wasn't able to get the help he needed despite paying repeatedly for help. Irvin doesn't speak and didn't appear to understand much English, his native language is Russian. Initially one of our volunteers spent a couple of hours over two weeks trying to help Irvin with different issues he was running into. Irvin's computer was old, even by our refurbishing standards - it was running the Lenovo version of Windows XP. Many of the issues Irvin was running into were due to the fact that he was still running Windows XP. Communication was our first issue, but Google Translate seemed to work well enough that we we...

If you haven't bought an SSD you really should

I just finished upgrading my home workstation from Xubuntu 18.10 to 19.04 and the upgrade not only went smoothly but finished in less than 30 minutes. This might seem like a long time, fresh installs can literally be minutes when using a flash drive to install to an SSD, but upgrades usually take a long time. Lately when someone asks what they can do to speed up their computer I almost universally recommend they upgrade to an SSD over upgrading RAM/CPU/etc. One of our local computer shops has been carrying a 120GB SSD for $26.99. I bought one of these SSDs about 2 years ago for $69.99 and at the time felt it was a pretty good deal. Although the write speed on this particular SSD is only 350Mb/s it's still much better than the speed of a 'spinning rust' hard drive. During a distribution update more than a thousand files get updated and often more than 2,000 files are downloaded. The process also involves deleting some packages, and unpacking a number of programs befor...
