[General Topics] Menneisyys:
Yes, it was quite a long ago that I've published my last Misc news. The reason for this is my having been really busy:

1. I've acquired a Tablet PC, a HP TC1100, and have read through all the Tablet PC forums. I've had some severe problems with the XP SP3 upgrade - see THIS if interested -, which was cured by a BIOS upgrade and/or forcing it to download the SP3 from Windows Update, as opposed to downloading it manually and doing the "Checked" Registry hack explained HERE. I've also tried setting up Vista Ultimate checked/debug with SP1 on it, but, unlike what others have reported, I was just unable to make the Wi-Fi card (in my device, the 2100) work. (And, of course, it's pretty slow compared to XP, even with the 1.5 GB of RAM and 5400 rpm 160 GB Samsung HDD. Dunno if it'd be faster with a 7200 rpm one - I don't want to have additional heat, noise and power consumption from switching to 5400 to 7200 for sure.)

BTW, speaking of the Wi-Fi card, I've also made some thorough tests to find out whether it's indeed as good as some TC1100, comparing its sensitivity and range to that of the new HP iPAQ 210 Pocket PC (running the default 1.00.06 stock ROM) and the Nokia N95 (with firmware version v21). I must state the reports on the TC1100's having great range are overly exaggerated. The iPAQ 210 has definitely better range. The TC1100 has about the same range as the Nokia N95.

The TC1100, otherwise is absolutely gorgeous. It does have some minor problems (for example, it's very slow at scrolling PDF files and, in portrait, the screen I have in my device isn't very well polarized; fortunately, the latter is less of an issue if you increase the backlight and don't use it at its lowest level), but, for a year 2003 model, it's just great, especially at the (current, second-hand) price, you will hardly find a better tablet. The alternatives would have been either much more (at least two times) expensive or considerably heavier - or both. The weight of the device (3.1 lbs, 1.350 kg without the detachable keyboard) is pretty much acceptable with a feather-weight (350g without the shoulder strap; 520 with it) bag like the 12" Tucano designed for the Mac Powerbook (and is, therefore, slightly oversized for the TC1100, but there simply wasn't a smaller bag in the shop) I've bought. Just a comparison: the 15" notebook bag I've received as the MS MVP gift in 2006 weighs 1300 grams - and, of course, is laughably oversized for a 10.5" tablet. A tablet, with the bag, weighing 1870 grams, is already very easy to carry everywhere. Just a comparison: my old 15" IBM Thinkpad a31p weighs, with the above-mentioned 15" MVP bag, almost 5 kg and is very hard to lug around. My favorite pastime, in addition to using it as a computer in the bed, is taking it out for excursions and walks. Two shots of my using it outdoors; in the second case, for video phoning, tethered it to the N95 via (feel free to zoom into the image - with the second shot, I've left it at 12 Mpixel, "only" decreasing the quality to reduce the storage need) Mobiola WebCamera:

The battery life of the TC1100 is also very cool. With the lowest backlight level, when just reading a book or a static, unanimated Web page (that is, no CPU-hungry tasks like Flash animations on Web pages are running), the power consumption is around 7 Watts. (Just for comparison, the one-generation older, Pentium 4M-based a31p consumes about 24 Watts the least. The more than three times more power usage is both caused by the older architecture of the CPU and the huge, power-hungry IPS screens. Unfortunately, IPS screens, while they have orders of magnitude better quality than plain TN + film TFT's, have always been pretty power-hungry.)

BTW, now that I also have a tablet, except tablet-related news & tips & reviews too in the future.

2. And yes, another (Microsoft) mobile platform I officially start to publish on: I've received a Microsoft Zune (second generation 8GB model), thanks to the Microsoft Company Store, which does ship them to abroad. Were I situated in the States, I would have access to its major selling point: the flat rate Zune Pass (costing US$14.99 a month), "take it (almost) all" store. Too bad while the hardware is already accessible outside the US and Canada, you still can't sign up into Zune Pass (you need to enter a valid US / Canadian address). I might ask some folks there to help to sign up? ;-)

Hardware-wise, I like the (second-generation) Zune pretty much, particularly now that there already is some kind of third party XNA app / game development for the device (see THIS and THIS for more info). I will definitely post on the latest news, hacks and, of course, development (games etc.) news on it too - but, for the time being, no Zune Pass / Zune Marketplace-related info as I'm in Europe and, as has already been stated, can't sign up for Zune Pass.

The stock earbud headphones coming with the device are really-really excellent (for an earbud, that is; of course, they can't beat supra-aural headphones or tightly fit canalphones [in-ear monitors]); they are of definitely better quality than the stock headphones (which aren't bad either) of the Nokia N95. My biggest grief is "just" the complete lack of A2DP (this is pretty much a showstopper on the long run) and the lack of a miniUSB or comparable socket for universal and easy synchronization / recharge access (no need to carry around the proprietary sync cable). I really hope Microsoft fixes these issues in the third generation Zunes due out next year.

3. Having read the written version of my recent W3C presentation, I've been invited by no one else than Dominique Hazael-Massieux, the Activity Lead and the co-Chair of the Test Suites Working Group, to contribute to the W3C Mobile Web Initiative. (BTW, he also has frontpaged my presentation and called it impressive, which is a BIG honor for me!) This means I needed (and will need) to get up to speed with the projects in there and will post even more Web browsing related, even more in-depth and developer-friendly articles on all the mobile platforms I support (Windows Mobile, Symbian S60, BlackBerry, MS Zune and, hopefully in the not distant future, the iPhone).

4. Of course, I've been working on my generic Bible on Digital TV, radio and all the like. The task turned out to be of epic proportions because I'll also elaborate on a lot of related subject, even on maths and digital signal processing. That is, I plan to give you an overall picture on what books there are on DSP, telecommunications techniques, which you should use for actually understanding how these technologies work etc. Be patient.
