It has been very hard to ignore pictures of flaming laptops. Problems as such have not only affected Dell, which is now recalling millions of batteries.. If you own a Dell laptop, consider this an important announcement.

Dell Inc.’s record-setting recall of 4.1 million notebook computer batteries raised safety concerns about the power source of countless electronic devices, but experts said the problem appears to stem from flaws in the production of the laptop batteries, not the underlying technology.

Apple has begun similar a initiative, wherein it collects batteries (quick replacements to be shipped). Additionally, in the United States, an agency has begun reviewing all of Sony’s laptop batteries. Dell partly blames Sony for its battery woes. Sony is responsible for one component of the batteries which Dell stocks.

O, there I am at work again. By all means it’s an ordinary day, but the unusual heat makes me want to stay inside where it’s air conditioned. Just a minute ago I saw a follow Ph.D. student slamming his mouse and keyboard. I could see an empty Windows XP desktop, so I can only imagine that it froze on him (possibly after an important overnight experiment). That’s just something, isn’t it? No access to the results and a whole night gone in vain. I’d offer him Linux (it’s already installed on his secondary partition), but I don’t want to risk alienation or become his ‘support guy’.

My computer was running from April to July (SuSE Linux 8.1) without a single reboot, but we had three outages recently. These were due to the heat wave that evidently affects London datacentres, as well as California (notably the half-day MySpace downtime). I even heard about Utah too last week… downtime reported in news:alt.www.webmaster. I then found a news release and reproted it to Walt as a possible proof that the Web host was not lying. I guess we must all have to cope with the effect of the weather on our servers. Everyone suffers the same, so balance prevails.

NE thing that keeps striking me as surprising is that people’s habits supersede all logic. I will provide an example from technology.

How can anybody argue that drive A for floppy disk and C for primary hard-drive is more rational than the rhetorical and self-explanatory /dev/floppy/ (for floppy device) and /dev/hd0/? This comes the prove that it is all just a matter of habits. People refuse to accept new things that they are not already used to, irrespective of their reasoning. In fact, the hierarchy of a computer (abstraction) in the *nix world is far more robust. It may also be easier for a new user to ‘digest’ and everything stems from the root of a single tree.

may have just helped in intercepting a key decision and plan. It was the plan of our Division to convert a Linux HPC cluster into a Windows Compute Server, deploying it across approximately 32 nodes.

Not everybody was happy with this decision which made by just one junior staff, especially after I had voiced my own opinions. That guy, a regular Windows user, was rather frustrated. He wanted to convert a perfectly-operational Linux cluster into something else. He wanted to do so because the *nix system administrator who runs the Linux supercomputer has recently left. Without much clue about the alternative route, he went ahead and made a proposition to the management, contacting Microsoft in the process.

It worries me when such decisions are pushed forward by people who are not qualified to judge. The initiator does not know anything but Windows, let alone is able to draw a comparsion between different high-performance solutions (IBM have clearly stated that Linux is superior in that arena).

The person in question was/is bound to go to a training course on using Windows supercomputing, but an afternoon IT staff meeting will review the whole plan and possibly scrape it. I feel as though I have, to some extent, prevented a huge and expensive mistake from being made. That was my Linux advocacy for today and it was done locally, where it truly matters, rather than over cyberspace.

Not the actual box. Treat as
placeholder for illustrational purposes.

When you see a great deal, you simply know it! 149.95 dollars will buy you:

• AMD Duron 2.8 GHz Processor with 800 MHz FSB
• 180 Gigabyte Hard Drive
• 256 Megabytes of RAM
• K7MNF-64 nVidia nForce2 Socket A Motherboard
• nVidia nForce2 chipset

[...]

The machine will of course run GNU/Linux. It seems too good to be true, so I remain skeptic. Having toyed with the cart feature, it seems to be genuine though. The site statistics (Alexa, Netscraft), as well as some other available products, seem to suggest it is real.

Noteworthy: get Windows and double the cost of the worktstation…

ESTERDAY I read about three-dimensional displays, which are said to require no glasses and make stereo-vision a reality. This seemed like ‘queue hopping’ from a scientific point-of-view, so I had to read it carefully and identify some points of skepticism. I was successful in finding some gaps and deficiencies, which a careful read would quickly reveal (albeit the headline is very eye-catching — an exaggeration within or even beyond reason).

If you have some idiosyncratic interests which pertain to the study of vision and human-computer interaction (HCI), you may find some of my past essays on the topic intersting:
