I haven't been reading many such complaints before (luckily I'm no lawyer;), but it's actually quite interesting to read the complaint from SCO.
84. Prior to IBM's involvement, Linux was the software equivalent of a bicycle. UNIX was the software equivalent of a luxury car. To make Linux of necessary quality for use by enterprise customers, it must be re-designed so that Linux also becomes the software equivalent of a luxury car.
Is your project illegal? Doesn't forbid the DMCA all this?
The DMCA forbids circumventing copy protection, but this is not our goal. We develop an alternative operating system for the Xbox gaming console. A side product could be the ability to run unsigned code, but this alone does not make it possible to play pirated copies of games. Nevertheless, if you live inside the USA or another country with a similar legislation, and you work on Xbox hacking rather than on Linux developing, you can of course join the project anonymously. If you are either a lawyer or a Microsoft representative, you are of course welcome to talk to us about any changes.
Geoff "Dissonance" Gasior at The Tech Report has made an interesting comment regarding how Lindows could potentially take advantage of open-source "R&D".
In danger of maybe repeating earlier posts, I thought I'd add a link to Håkon Wium Lie's (CTO in Opera Software and the guy behind Cascading Style Sheets) view on the current DVD trial case. He sees clear analogies between the movie business' wish to decide how the content of a DVD should be played, and the wishes of Microsoft and the likes who among other things want to use proprietary and possibly encrypted formats on the Web.
I'm not on anything. Also, if you read it properly, I said "around" and not "on". There's a difference. However, it is widely recognized that Bluetooth and WLANs are based upon the IEEE 802.11-standard. See here for example.
Although 802.11 is designed as a communications channel to a host processor running TCP/IP, and Bluetooth defines more communications protocol layers and implements real applications, a Bluetooth device has for instance a unique 48-bit address from the IEEE 802 standard.
No, it's for the countries using NMT 450. NMT (Nordic Mobile Telephony) is the classic cellular standard used in 30 countries around the world. NMT operates on two different radio frequencies, 450 MHz and 900 MHz.
Essentially, the GSM 400 is a migration path from the NMT to the GSM system. GSM 400 will evolve with the core GSM specification and will include seamless roaming with other GSM bands.
Global System for Mobile Communications (GSM): First introduced in 1991, GSM is the largest digital mobile standard in use today. Implemented in 400MHz, 900MHz, 1800MHz and 1900MHz frequency bands.
General Packet Radio Service (GPRS): An enhancement for GSM and TDMA core networks that introduces packet data transmission. GPRS uses radio spectrum very efficiently and provides users with "always on" connectivity and greater bandwidth.
Time Division Multiple Access (TDMA): A mobile communications technique in which a radio frequency channel is divided into time slots, each of which lasts for a fraction of a second.
Enhanced Data for GSM Evolution (EDGE): A technology that gives GSM and TDMA similar capacity to handle services for 3G. EDGE was developed to enable the transmission of large amounts of data at rates of 384 Kbps.
3rd Generation (3G): Third generation is a set of digital technologies that promises improvements in capacity, speed and efficiency. 3G also goes by the names, Improved Mobile Telephone Service 2000 (IMT-2000) and Universal Mobile Telecommunications System (UMTS).
Universal Mobile Telecommunications System (UMTS): A 3G standard, being developed under the auspices of ETSI, and intended mainly for the evolution of GSM networks.
Code Division Multiple Access (CDMA): A technology for digital transmission of radio signals that uses digital encoding and spread-spectrum RF techniques to let multiple users share the same RF channel. In CDMA, a frequency is divided using codes, rather than in time or through frequency separation.
Wideband Code Division Multiple Access (WCDMA): A 3G wideband radio technique which makes highly efficient use of radio spectrum and is capable of supporting data rates of up to 2 Mbit/s, sufficient to allow simultaneous access to several voice, video and data services at once.
I agree that with efforts from various Wi-Fi alliances (such as the coming Wi-Fi Smart Card organization), current issues with security, privacy, roaming, and also convenience, will be, atleast mostly, solved.
However, 3G has an important advantage. Whereas 802.11 is limited with regards to speed and mobility, 3G (UMTS together with WCDMA) provides different data rates:
* 384 Kbps with a maximum speed of 500 kilmometers per hour.
* 512 Kbps with a maximum speed of 120 kilometers per hour.
* 2 Mbps at a maximum speed of 10 kilometers per hour (a little faster than walking speed.)
The power consumption is also lower with UMTS+WCDMA than with current 802.11x.
The carriers see this as a complementary service. The WLAN market is on the verge of rapid growth, and this is mainly due to the large carriers interested in the "hot spot business". T-Mobile is an example of this. It is also becoming quite apparent that 3G traffic will be mostly voice, so Wi-Fi data traffic will not deprive carriers of revenue there.
One must also remember that, unlike the technology sustaining them -- 802.11b, 802.11a, etc. -- there is not an agreed-upon, or proven, business standard which investors and operators may follow. You have the "everything is free" and the "do it yourself" thing. None of these models are "perfect" when it comes to cost, revenue, benefit and risk sharing.
Bluetooth draws heavily on existing wireless LAN technology since it is based around the IEEE's 802.11, and like 802.11, it operates in the unlicensed Industrial Scientific and Medical (ISM) 2.4 GHz band. The main differences are that in order to consume less power, Bluetooth is initially restricted to an operating distance of just 10 metres and a speed of approximately 1 Mbit/s.
It is interesting to notice that in a recent survey done in Norway (see here in Norwegian, sorry), 6 of 10 Nokia phones must undergo repair during its first six months.
This would indicate that it is becoming increasingly more difficult and expensive to (among other things) develop sophisticated software for new phones. Symbian may be seen as a response to this. However, we won't see the share of Symbian enabled phones hit 30-40% until 2005+ or so.
I agree. In addition, many cell phone manufacturers (including Nokia, Ericsson, Siemens and Motorola) have the advantage of working with next gen infrastructure too. They draw big benefits of testing their phones on new equipment before the infrastructure is let loose in the market, i.e. sold to (potential) competitors.

Anyone have experience with and/or links to tests regarding the noise level in VapoChill and water cooling kit systems?
