Lookin Good

LooKInMyPC won’t fix your PC the next time it throws a wobbly, but it might make it easier for you, or someone who knows their way around computers, to track down the fault. When called into action it produces a detailed system profile and diagnostic report about all of the hardware, running services, drivers, updates, startup programs, networks, Internet connections, event logs and a zillion other things about your PC that could prove useful. Save the report when the PC is behaving itself and if things do go awry and help isn’t at hand you can email the report to a knowledgeable friend or tech. You don’t even have to install it on your PC after you’ve downloaded the program you get the option to install it on your hard drive, or on a removable drive or UDB memory stick. Hopefully you’ll never need it (some hope…) but if you do, it’s ready to help.

Solar Nanotubes Make Light Work?

I have been reporting on developments in photovoltaic cells for as long as I can remember and there’s always some new technology or fabrication method that’s going to improve upon the woeful efficiency of today’s silicon based solar cells. I’m still waiting and outside the labs most commercial cells still only manage a fairly miserable 20 – 30 percent efficiency, which basically means that during their lifetime very few solar cells ever recover the enormous amount of energy put into their manufacture, let alone live long enough to generate ‘free’ electricity. I have no doubt that one day the problem will be licked and this might just be the development to do it. It’s a rolled up graphene layer nanotube and it’s the brainchild of a team of researchers at Cornell University. The first problem, though, is that it’s tiny, no larger than a DNA molecule, which means you’ll need an awful lot of them to do anything useful. The good news is that it’s very efficient and when exposed to light the tubular structure creates more electrons, and the cylindrical structure makes it easier for them to flow. I know, we’ve been here before so don’t hold your breath, but one day, it will happen, and maybe, just maybe this is where it started…

Apple Keyboard Hack Proved Possible

Slashdot reports that Apple keyboards are vulnerable to hackers’ attacks due to the complexity of their inner workings, which include RAM and flash memory. According to the report, the hack can potentially place keyloggers and malware directly into the device’s firmware.

To make matters even worse, the author of this “proof of concept” has also published the presentation and code in a PDF that’s free to download for anyone on the planet. The vuln is undoubtedly enticing to hackers, some of which are likely to create one or more exploits for the flaw in question. To better understand how this discovery has turned into a potential security issue, we offer you a few excerpts from the published document.

For ethical reasons, the firmware modification we describe is benign. The firmware is modified so that the LED under the CAP S LOC K key of the keyboard will flash momentarily when the keyboard is first plugged into a system. However, malicious payloads can be developed by individuals with mal-intent. Read more
