Re:Amazon.mp3
I prefer something I can actually get. Most of the aps on my Wing are open source, and nothing else is filling the OS gap for me on any device I can currently afford.
I'm not opposed to an open source mobile OS, if I could get a slim, functional Ubuntu on my Wing I would be all over it. It appears that some inroads are being made, but nothing is 'ready for the palmtop' yet.

Re:video resolution...bleh
Yes, but that's not the sub-$100 model number. That model is:
CPU:VIA C7-M 1.6GHz 400MHZ FSB
RAM:512 DDR II Memory
HDD:30GB
OS:Linux / Windows XP / Windows Vista
Windows Vista:7" WVGA LED Backlights (800 x 480)
Net work:Wireless Lan 802.11 b/g
10/100M Ethernet Controller
Card Reader:Push-push SD socket
Audio:Built-in Microphone and dual speakers
Input/Output:USB 2.0 X 2 VGA
Microphone jack
Headphonejack RJ45
Battery:3 cell/3 hours
Weight:900g (including battery)Which is NOT the one in the video -- and is not the model number in the video. If that model number IS the sub-$100 notebook, then either the manufacturer's specs are wrong on the site, or they have two models with completely different specs with exactly the same model number.
From http://www.linuxdevices.com/news/NS9413803799.html (the 6th link when googling for that model number): "HiVision's site, which offers pages devoted to its NBx line of notebooks, but which at press time has yet to post information on the new miniNote, should be available here."
The MiniNote is NOT the NB0700

Re:Don't count on it...
According to Linuxdevices, the manufacturer was selling them for $180 as of 3 months ago: http://linuxdevices.com/news/NS9047481010.html
$60 in 3 months is a big sudden price drop, and 100% seller markup is pretty hard to believe.

There's better products out there /w more RAMMost developers are using a Beagleboard @149 for a MIPS development platform; though like a few other development platforms as the MagicEyes Pollux, was only a precursor to the actual product. I'm puting the money on a Pandora
/w features as:* ARM® Cortexâ-A8 600Mhz+ CPU running Linux * 430-MHz TMS320C64x+â DSP Core * PowerVR SGX OpenGL 2.0 ES compliant 3D hardware * 800x480 4.3" 16.7 million colours touchscreen LCD * Wifi 802.11b/g, Bluetooth & High Speed USB 2.0 Host * Dual SDHC card slots & SVideo TV output * Dual Analogue and Digital gaming controls * 43 button QWERTY and numeric keypad * Around 10+ Hours battery life
It's no Indrema console, and better designed. At $350 per unit, It's not cost effective as a Sony PSP or Nintendo DS, but competitive to a mix between a QWERTY PDA with usable RAM/TV-out/redundant-expansion. In other words, it's a trade-off of a better Motorola A12000 CellPhone without the lock-in, more battery life, and better than the bulk of a laptop.
I'm somewhat nervous towards the that communist KOREA government-sponsored Gamepark Holdings' GP2x Wiz. It may be better designed as a gaming system, but it lacks the keyboarding of a PandoraArm9 533mHZ processor, 2.8" oLED touchscreen, 3D Accelerator, and 64MB RAM
GP2x Wiz is looking more like a MagicEyes Pollux SOC board.

Re:Slow News Day
Their 'supplier' has changed its licensing terms specifically to put them out of business. Companies get antsy about that.
They mentioned GPL3 in their annual report to the SEC
http://www.linuxdevices.com/news/NS5304340445.html
In addition, the GNU Public License is subject to occasional revision. A proposal for changing the license from its current form (GPLv2) into a newer, more restrictive version called GPLv3 has been proposed and is currently undergoing community review. If the currently proposed version of GPLv3 is widely adopted, we may be unable to incorporate future enhancements to the GNU/Linux operating system into our software, which could adversely affect our business.
in fact they regard GPL3 as a threat to Linux on the same level as SCO's lawsuit.
Our TiVo software includes parts of the Linux kernel and the GNU/Linux operating system. The Linux kernel and the GNU/Linux operating system have been developed and licensed under the GNU General Public License, version 2 and similar open source licenses. These licenses state that any program licensed under them may be liberally copied, modified, and distributed. The GNU General Public license is a subject of litigation in the case of The SCO Group, Inc. v. International Business Machines Corp., pending in the United States District Court for the District of Utah. SCO Group, Inc., or SCO, has publicly alleged that certain versions of the Linux kernel contain unauthorized UNIX code or derivative works of UNIX code. Uncertainty concerning SCO's allegations, regardless of their merit, could adversely affect our manufacturing and other customer and supplier relationships. It is possible that a court would hold these open source licenses to be unenforceable in that litigation or that someone could assert a claim for proprietary rights in our TiVo software that runs on a GNU/Linux-based operating system. Any ruling by a court that these licenses are not enforceable, or that GNU/Linux-based operating systems, or significant portions of them, may not be liberally copied, modified or distributed, would have the effect of preventing us from selling or developing our TiVo software and would adversely affect our business.
I bet they have a Tivo in the works based on an alternate OS just to cover themselves.

CF cards and poor DMA support...
Turned out it didn't fully support DMA...??? Like they didn't complete all the traces properly...
This problem is rampant in many flash card models and brands - even ones that claim to support DMA or UDMA. Search around on the interweb using your Napster machine and you'll see many others with the same issues.
After trying a Transcend 4GB 133x that would only work in PIO mode, I got my hands on a Ridata 4GB 266x that *does* work in DMA. So if anyone is considering that card, maybe that's a good sign. :)Mechanical challenges turned out to be not the only ones waiting for me when I worked on connecting the CF cards to the camera. These cards were hanging when the CPU tried to read them using DMA mode (and the card identified itself as supporting DMA mode). I tried to find the problem, and used all the tools I had. I added a bunch of printk's to the driver source, tried different speed settings for the DMA, and finally used an oscilloscope to spy on the signals between the CF card and the CPU. What I found was that the card did actually send the data using DMA mode, but always only for two "sectors" (1024 bytes total), regardless of the number of blocks to transfer written to the corresponding register. Then it silently hung, without activating an IRQ line, even if it was asked to transfer just a single block. And the CPU was relying on that interrupt to continue with the processing of the data read from the CF card. Careful examination of the data on the IDE bus did not reveal any problems (I was expecting something specific to the ETRAX). The same CF card with the DMA mode disabled in the driver worked fine (but slower, of course), as did the IDE hard drive (or SATA through the bridge) with DMA enabled. Googling the issue showed that I'm not the first to have problems with CF cards and DMA. The driver itself had a blacklist for some of the devices that caused problems. -- http://linuxdevices.com/articles/AT5102023409.html

Re:So what?
Before this Flash and Silverlight stuff, wasn't there MPEG streaming? I seem to recall watching streaming video in the mid 90s. IIRC, Flash video hit the big time when they guys who did YouTube used it to show video over dialup to family members. They created YouTube after they realized it was usable and others probably would be interested.
As far as Silverlight goes, from what I've heard, it uses Microsofts VC1 codec which is like streaming WMV files. There is no comparison between Flash FLV streams and Silverlight WMV streams. It seems FLV is light weight and lossy by design while WMV is more akin to standard video streaming.
I also recently saw where Move Networks is supporting Linux MID devices with a video player:
http://linuxdevices.com/news/NS8810160105.htmlMove Networks was used with Microsoft's Silverlight to stream the DNC and possibly the Olympics. IIRC, it is an ISP streaming caching system which streams from the ISP network to keep the bandwidth inside that network instead of steaming from the Internet to every client viewer. Could be some UDP or other tech used but the idea is source the stream close to the viewer.

Re:No -- the GPL is not a usage license (Moglen)
On usage vs distribution, from Eben Moglen's Questioning SCO paper (my highlighting with bold):
In general, users of copyrighted works do not need licenses. The Copyright
Act conveys to copyright holders certain exclusive rights in their works. So
far as software is concerned, the rights exclusively granted to the holder
are to copy, to modify or make derivative works, and to distribute. Parties
who wish to do any of the things that copyright holders are exclusively
entitled to do need permission; if they don't have permission, they're infringing.
But the Copyright Act doesn't grant the copyright holder the exclusive
right to use the work; that would vitiate the basic idea of copyright.
One doesn't need a copyright license to read the newspaper, or to listen
to recorded music; therefore you can read the newspaper over someone's
shoulder or listen to music wafting on the summer breeze even though you
haven't paid the copyright holder. ....But don't users of free software make copies, and need a license for
that activity? The Copyright Act contains a special limitation on the exclusive
right to copy with respect to software. It does not infringe the copyright
holder's exclusive right to copy software for the purpose of executing
that software on one machine, or for purposes of maintenance or archiving.
Such copying also requires no license.Eben has defended the freedom of usage from constraints on several occasions, so it's hard to see how anyone could gain the opposite impression. For example, in his public discussion with Tim O'Reilly he said:
"We've got to conclude that what Google does, they have a right to do in freedom. They shouldn't need anyone's permission to run programs. Stallman was right about that at the very beginning. If you have to ask other people's permission to run a program, you don't have adequate freedom.
I'm not too sure which statement of Stallman's he had in mind there, but it's certainly reflected in the FSF's general position on free use of GPL software.
And presumably this is why the FSF has phrased the GPL to be consistent with the above: the GPL doesn't limit usage whatsoever, only distribution. The GPL is not a usage license, neither by intent as expressed by the FSF ("the freedom to use the software for any purpose"), nor by legal applicability of Copyright as a constraint on use as Eben Moglen explained in the SCO paper.

Re:Think Antarctica
Microsoft is (and has been for a few years now) fighting hard against the Linux tide on the sub-desktop. Currently, they say its 50-50... but that was years ago. I guess that's why the first result in every API search at the time returned the WinCE version.
Fast forward today, and Windows is sliding against the Penguin, which could suggest why the first result in every API search returns the
.NET equivalent, and how if you install the Platform SDK, you cannot uncheck the option for .NET embedded APIs.So.. Linux for the future, I reckon so simply because the biggest and best weathervane for increasing Linux adoption is shouting how worried they are (ie Microsoft). If MS were ignoring Linux and F/OSS then I'd think it was all hype, but as they're coughing up cash for various OSS projects, declaring how open-source friendly they are, creating their own OSS repository sites (codeplex), getting various OSS projects better integrated with Windows.. all that just shows how worried they are, so Linux is a big deal at the moment.

Re:This is not a "$12 computer".
4. Develop a SIMPLE Operating System for it. Linux is way too big for the sort of cheap ARM chips available today. Most modern BSDs are also probably too big. Think much smaller. UNIX used to run on small machines though so it could be POSIXish.
I understand and agree with some of your comments, but this one was just ignorant. I am assuming you have never heard of the linux distros that fit on a floppy? An Example: http://www.linuxdevices.com/links/LK8414188089.html Not only do they fit on a floppy but they typically will have a web browser, FTP,Telnet and SSH.

Midori is already a browser.
It's quite sad that Microsoft feels the need to steal the name of an existing browser for their new browser-based project. A simple Google search reveals there's already a Midori browser. The company Steve wants to buy reveals the same thing. Even MSN knows about it, so Live Search isn't left out.
Transmeta even had a Linux distribution meant for Internet appliances called -- you guessed it -- Midori.
How about a little due diligence, Microsoft? Or is the plan to just lie, cheat, steal, and discredit credit-worthy opponents in the eyes of CIOs and the press? What about the new, nicer, more open Microsoft we keep hearing about? Is that just more underhanded marketing building on the goodwill of truly open companies?

Re:Obligatory...
Encapsulation, scope, etc etc, is 101 stuff. I find it hard to believe any programmer, OSS or not, doesn't know them. Are we talking script kiddies perhaps?
Stripped down Liunx is far from a myth. (Try 50MB DSL http://www.damnsmalllinux.org/) That why it's used in embedded devices. Some of which you can find at:
http://www.linuxdevices.com/
You don't have to start with a big fat distro. A full desktop system is silly for kiosk, I would argue so is x86.
Yes all this can be said for WindowCE (which you should be using over XP any day for this kind of thing!!!), but the difference is that Linux is the same OS, from watch to super computer.
D-Bus dependencies don't seam that crazy if you don't count the all the bindings (if you are including Mono, what did you expect?)

Re:There is a reason
Do you work in the embedded applications industry? I can tell you that Linux is and remains quite toxic to the business community b.c. of the GPL and the perception of substantial legal risk thereof. Cisco for instance is making a push to use a FreeBSD derivate in all of its consumer products--displacing in some cases existing linux based hardware.
Heh, while at the same time embracing Linux for their professional Integrated Services Routers. You may be familiar with the 1841, 28xx and 38xx series? Many people are.
BSD has enjoyed tremendous penetration into the commercial marketplace. Linux is included in a handful of devices--decisions attributable to a wave of linux euphoria which has now mostly dissipated.
Hi! And welcome to this planet. You seem to be a tad out of touch with the current marketplace reality, so let me give you a quick update and assure you that Linux is everywhere.

Re:Wi-fi/web server based remotes
Mac
Or if you don't like sucking Apple off, you could always get this (or the earlier model, the N770 for about $150) and you're in business. The N770 is a completely open platform, if you've got some developing skills up your sleeve you can write your own application. If writing code isn't your thing, I've seen a couple of free projects that allow you to control your PC remotely, and even one commercial one. ... iPod Touch ... iPhone
The N770 is a pretty reasonable alternative to a keyboard and mouse, plus you can take it around the house or mount it somewhere for parties to let people have a bit of control of the music. Also, resolution permitting you could run a copy of VNC Server Enterprise and use VNC Viewer Enterprise which allows dynamic resizing of the screen to fit on your tablet for when you need to do a bit more than what your web interface allows. -
ease of use and Linux ..
"It exists malware for both Apple and Linux too, but not in the same volume as for Microsoft's OS:es"
What about on servers, there's an aufull lot of nix boxes out there, with lots of jucy creditcard details on them.
"This way of relaxed behavior is kicking back because it also makes it easy to create malware"
Ease of use doesn't necessarly lead to lax security. A locked down Linux box can still provide a full feeture experience. You can click on URLs and open email attachments with 99.999% safety. Chief reason being that 'OPEN' isn't the same as RUN.
On non Unix platforms, you should run all the security bits on an embedded device, that way the 'malware don't compromise security. -

Licensing containment barrier??
I went on to read their in-depth article (linked to the main article) at http://linuxdevices.com/news/NS8981295285.html and I found this:
"Another touted benefit is the ability to consolidate control- and data-plane functions on a single device, with "solid-wall" processor boundaries reinforcing security and licensing containment barrier. In this regard, the Tile64 chip resembles another heavily multicore MIPS64 chip, Cavium's 16-way Octeon."
Does anyone know what the heck a "licensing containment barrier" is? It definitely sounds like a performance hit if it's turned on. And if it's forced to have it on then this design just lost a lot of its sex-appeal. -

He who controls the bootloader determines which systems is used by the general population. Ubuntu is already easier to install and maintain that WIndows, as are most linux distros. The barrier is that they have to be installed, for the most part. That's being beaten by pre-installed Linux. But notice that there are no dual boot machines on the market that also boot to Xp. There are dual boot like the PS3, but no dual boot with Windows. Afraid someone will compare the systems, or what?

Re:Laughably high power consumption for handheld
From Linux Devices: http://www.linuxdevices.com/news/NS5492118276.html
ARM vs. Atom
There's much to like about the Intel Atom, writes Williston in EETimes. Yet, he suggests, the media and its readers may have been overwhelmed by the hype machine. Williston offers the following responses to typical arguments from the atomic power lobbyists, at times quoting analysts such as Forward Concepts's Will Strauss to back him up:
Atom will beat ARM because it can run Vista. -- No it can't, says Williston. Atom can run Windows CE and Linux, but ARM can do the same.
Only Atom offers a "real" Internet experience with Flash video, YouTube, etc. -- "Wrong," writes Williston, pointing to ARM Flash players from BSquare, and an ARM-based YouTube decoder from On2. He might also have noted that Nokia's ARM- and Linux-based Internet tablets use a Mozilla-based browser, with plugins for Flash, Windows Media files, and even Microsoft's Flash-like Silverlight technology.
Intel dominates every market it enters. Here, the writer refers the reader to the history books, especially two years ago when Intel sold its PXA line of embedded processors to Marvell after failing to dominate the market for ARM-based SoCs.
Atom will win because ARM is proprietary technology. Nope, he writes. ARM chips are available from a number of semiconductor vendors.
Intel will win on cost. Not likely, he writes. Using a 65nm process, the Cortex-A8 occupies less than 3mm x 3mm, he notes, while the Atom core probably takes up about 9mm x 9mm of Atom's 25mm x 25mm die size, despite its smaller 45nm process. "With such a huge area disadvantage, it's hard to see how Intel will win on cost," he writes.
Intel will win on power. Once again, not likely, he argues. Intel quotes a thermal design power (TDP) of 0.6W to 2W for Atom, he writes, but doesn't specify clock speeds. ARM offers only "typical" power measurements, making comparison difficult. But at best, he suggests, Intel matches ARM on power usage, while "in most scenarios, Atom burns more power."
Intel will win because it has the most advanced fabs. Perhaps, he writes, but who cares? "Consumers focus on cost, power and speed," he writes. -
Re:Jeff AlbertsonPOS on linux is not at all new Indeed, Linux grew 32 percent year-over-year, according to figures released by IHL Group. The research firm reckons Linux accounted for $475 million of the $5.56 billion market, putting it third overall with an 8.5 percent market share.
32 percent is actually low growth in that sector for Linux. Linux would have a much larger share of POS today if Microsoft had not pulled out all the stops a few years back when Linux threatened to make major gains.
"We began the year projecting 300-400% growth for Linux," says Greg Buzek, President of IHL Consulting Group. "But two large retail defections from planned rollouts of POS units greatly hampered the growth of the operating system. Musicland was just about ready to roll with Linux when they were purchased by Best Buy, a Windows NT shop. Best Buy changed those Linux plans. And Home Depot also was looking to roll with Linux at the POS, but those plans were nixed when the company made several management changes."
So Microsoft succeeded in slowing Linux in the retail sector by that and other means. But by no means stopping it. Linux's success in the cell phone, umpc and embedded applications of all description plus IBM's support will no doubt contribute to a resurgence of Linux growth in that sector. -
Your lucky dayLinuxDevices.com has a recent article on Linux POS. http://www.linuxdevices.com/news/NS8365122751.html

Re:Which one?
There are worst-time patches and CPU binding patches for Linux. Not only that, but many embedded applications are not, in fact, in need of an RTOS at all. Linux won't displace QNX, LynxOS, and VxWorks completely, but to say it's not making gains in the embedded space is either disingenuous or ignorant of the facts.
It'd also be pretty big news to, for example, MontaVista, Nokia, Cisco, and the BlueCat folks that embedded Linux isn't making any sales. -

What's the real story?The summary and TFA seem to talk about one day coming up with lip-reading computers, which we've had for a while, and was open sourced and is apparently now on Sourceforge.
TFA links to a paper that's actually about exaggerating lip motion to improve recognition, which seems like an interesting topic, at least new to me. But it's seemingly unrelated to the reporting or any governments protecting us from our rights.
From the Abstract:Accurate lip-reading techniques would be of enormous benefit for agencies involved in counter-terrorism and other law-
enforcement areas. Unfortunately, there are very few skilled lip-readers, and it is apparently a difficult skill to transmit,
so the area is under-resourced. In this paper we investigate the possibility of making the lip-reading task more amenable
to a wider range of operators by enhancing lip movements in video sequences using active appearance models. These are
generative, parametric models commonly used to track faces in images and video sequences. The parametric nature of the
model allows a face in an image to be encoded in terms of a few tens of parameters, while the generative nature allows
faces to be re-synthesised using the parameters. The aim of this study is to determine if exaggerating lip-motions in video
sequences by amplifying the parameters of the model improves lip-reading ability. We also present results of lip-reading
tests undertaken by experienced (but non-expert) adult subjects who claim to use lip-reading in their speech recognition
process. -

Re:Alternate OS?
Does have Linux, if you go to the White Box Robotics website, they have a version with Ubuntu. That's the "Player" software on their site. Since they're running mini-ITX motherboards, Linux should run OK. Not cheap, the MS version is ~ $8K, with the Linux version at ~$6.8K.
For my money, I'd spend $350 and get the Pleo, it does run Linux on an ARM CPU. Would be more fun to work with too! http://www.linuxdevices.com/news/NS9421520726.html -
Letter to NetGear re: Linux devices
I sent this letter to NetGear a few days ago:
--cut here--
I like the fact you are using Linux in some of your products, as seen here:
http://www.linuxdevices.com/news/NS3943657768.html
A product I and I am sure many other enthusiasts are interested in:
A line of inexpensive, small, software-reconfigurable "appliance" computers
that can be easily repurposed by reloading different software. I would like a
vendor who provides a supported "image" for various applications but who allows
custom applications to be loaded at will.
Such an appliance would have one or more of the following options:
- a drive bay or bays, for use as a NAS server
- USB port or ports for printers, scanners, drives, or other devices, for use
as a device server
- 3 or more ethernet ports that can be put on separate networks or used in a
one-IP-addressable-port/two bridged ports for use as firewall device
- wireless network or networks for use as a wireless router, access point, or
repeater
- CPUs and support chips of various price points and capabilities to match
various loads. A typical home/SOHO configured as a WAP+firewall+printer
sharer+NAS would likely need a medium-performance board, a home/SOHO configured
for one of those purposes would need a low-performance board, and a gamer would
need a high-performance board.
I would expect a "bare bones" setup that only did one function with light duty
to start well under $50, with high-end systems going for several hundred plus
the cost of high-end wireless transmitters, drives and cases for drives, etc.
The most important feature of this line would be customization:
A user who needs features supported by the hardware but not the firmware should
be free to customize the firmware to his heart's content. The only exceptions
would be for the brick-recovery emergency-boot firmware which should be
read-only. Individual physical subsystems such as the wireless transmitter,
USB hardware, ethernet hardware, SATA hardware, etc. should of course enforce
regulatory and standards compliance.

Please send your own letter to NetGear thanking them for choosing open-source. Better yet, buy products that use embedded open-source. -
Pico is also obsolete
Surely you meant to bring up the mobile-ITX form factor, which is half the size
;) -
How about a better summary first?
Yeah, because there haven't been 386, 486, and other systems on a chip and Via doesn't have a 1-watt processor anywhere to be found. This is not the first 1-chip chipset for all of the x86 line. That's bullshit. An SoC is even more integrated than just having the chipset as one chip. Somebody never read the old Computer Shopper before it slimmed down. SoC solutions for x86-compatible systems have been around more than a decade. The summary is bad, because TFA does not say this is a first for the x86 line.
You're right that even low-powered x86 chips like the C7 and the Geode line are generally no match for ARM and XScale. MIPS I'm not as familiar with for power usage purposes. It'd be nice if that question was answered, but I'm afraid it'd be summarized incorrectly too.
