Installing Fedora on the Aspire One (D255)

Dec. 30, 2010, 11:59 a.m. broadband , netbook

Trying to figure out why the Aspire netbook ships with Windows 7 Starter. They could have shaved a little bit off the price by shipping it with linux, Instead of charging extra for a useless OS. They don't need to make us go through the trouble of installing linux on our own. Fortunately installing ...

gpg: decryption failed: No secret key

Dec. 28, 2010, 11:45 a.m. netbook , security , X11

GPG (or PGP) is something that even geeks often have trouble with so I was happy that I had a working installation of gnupg with keys properly setup. Then I needed to decrypt a file while on my newly aquired netbook running Fedora 14. It seems the GPG package on Fedora 14 is different from what I've ...

Replacing the display on an HP Nx7400

Blank screen disease is something that plagues not just Macbooks but other computers as well. Recently my uncle's HP Compaq NX 7400 was infected by it. While most of the time blank screen issues can be traced to a software bug, on this occasion it turned out to be a dead LCD. In fact dead LCDs are ...

Review of the Aspire One D255

Dec. 19, 2010, 4:45 p.m. aspire , Macbook , netbook

I've been having the Acer Aspire D255 for two weeks and I just love it. Netbooks are often derided as not having enough processing power for anything useful. Most people just use their computers for browsing, email and word processing and for that even a lowly Intel Atom processor has far too much p ...

While I was working in frenzied rush to finish off my MBA asignment, the hard drive on my Macbook died on me.

Picking a mother board.

Having chosen an AMD Phenom II as the processor, it's time to choose a motherboard. There are enough brands and chipsets to make even a geek feel confused. First up, I wanted it to be something other than Asus. A toasted Asus mother board is the reason that I am having to do this rebuild in the firs ...

Choosing a processor.

Intel's Core i7 processors, packed with upto six cores, and two threads per core, provide enormous processing power for desktops that was beyond anyone's imagination even four or five years ago. But the question is do you really need such power. The answer is hell no! Most people use a computer to a ...

Never been a fan of RDBMS no sirree. But that has never stopped me from using them (but with many repitions of the phrase 'databases suck'). Then along came non relation databases and then no-sql. For a while I had to modify my phrase to 'SQL Databases suck'. But it wasn't long before I started dabb ...

Copyright or Copyleft?

Yesterday's Lakbima newspaper carries an article saying copyleft is a figment of daya dissanayake's imagination. You can bet your hard disk that this guy laboriously wrote that article with pen and paper and then went with it to the post office to send it off to the editor. Because if he had access ...

Just a few weeks back I mentioned that I had three computers. It never pays to boast because now I am down to two. For a very brief period, I was actually down to just one. All three of them had failed at different times and two of them went together. But two of them have been restored. The travails ...

From P5B SE to P5B VM SE

On October fourth, nearly a month ago, I tweeted about a toasted Asus P5B SE mother board and about breaking my life long habit of not claiming a warranty. It turned out to be such a waste of time. The owner of the shop from which I bought the mobo, is a decent bloke. Wish I could say the same about ...

The other day, I mentioned that I have three computers. Now I am down to too. The mobo on one of them died, it wasn't entirely unexpected. For a while now this computer in question has been behaving erratically and needed a few reboots. It refused to stay up for more than a day or two at a stretch. ...

The Colombo Stock Exchange is open from 9:30 AM to 2:30 PM each day. Then why did the CDAX online trading software's ticker continue to run well past the closing time on the 24th? I will tell you why; because this system is not real time and this software is written in Java. I've blogged about ...

Yet another dead macbook

Dell is in a lot of hot water for shipping lousy hardware. One wonders why the same fate has not befallen Apple, the company that is so arrogant as to elegantly package a brick and call it an iphone or an ipad and charge you heaps of money for it. Macbooks are only slightly better. It was only a cou ...

Amazon recently announced that S3 support has been enabled in the AWS management console. Sounds great. Except that it doesn't work. Once you click on the S3 tab in the console the process seems to hang. The reason amazon and other cloud hosting companies want us to switch over to the cloud is becau ...
