VIA Nano QuadCore (X4)

Thursday, May 12th, 2011

So VIA now enters the game of many-core with the VIA Nano QuadCore.

Unfortunately, however, the dual-core VIA Nano X2 did not yet even made it to the market. The VIA Nano already was years late, and so is the X2. I guess this time they may ship the QuadCore sooner, because it mostly consists of two X2 dies, which will probably help to start shipping the X2 and QuadCore in a similar timeframe.

Without all these delays, or slow development –whatever you want to name it– I’m sure VIA would have been more successful over the last years. This way Intel and AMD could get into the lower-power market easily, and quickly. And this while Intel’s Atom is only deliver an “abysmal” year 2004 Transmeta Efficeon performance.

The X2 and QuadCore thermal design power (TDP) is not that low either, 25W for the fastest X2, and 27W for the (lower-clocked) QuadCore + ~5W for the chipset and graphics. AMD’s Fusion E-350 runs at 18W, while the C- and G- series are down to 5W-9W, including the memory controller and graphics: Fusion.

VIA will continue to have a hard time competing against AMD’s high-performance, low-power offerings, as well as Intel’s less-performing either lower-power (Z-series Atom) or higher-power regular Atoms.

PS: What surprises me in Anandtech’s report is, that VIA Centaur is running their simulation cluster with Intel CPUs. I certainly would not feed my competitor, and instead rather use my own CPUs. This would not only thoroughly stress test them, but also motivate the engineers to develop performant next-gen chips, … And: You seriously expect other cloud folks (Facebook, Google, et al.) to run clusters of VIA CPUs if VIA is not even doing so in-house???

Where are the pretty PC laptops?

Thursday, March 17th, 2011

My main “workstation”, a 3 year old MacBook Pro, is really reaching the point where something slightly snappier would be nice. As I also use Linux a pretty PC laptop would be sufficed, too. Especially as I do not 100% fall in love with the latest unibody Macs, anyway (I would take a black liquid-metal incarnation, though, … ;-) .

With the advent of neat silicon from AMD there should be plenty of slim, light and long battery life PCs, but there aren’t, … :-( The only thing one could barely consider was the previously expensive, and now discontinued Dell Adamo, … With this good design vacuum it is no wonder Apple is selling that well, …

I could consider the new Lenovo X220, the IPS display is certainly appealing, but where the heck is the ultra-portable, slim & light S-series edition of it?

Oh my, guess I have to wait even longer, and if the PC industry continues to fail with good designs, I can just hope to see some nice liquid metal, black & beautiful Apple laptop in a year (or so), …

Tip of the week: keep paper feeder rubber clean

Tuesday, February 8th, 2011

For some time our office’s Konica Minolta Magicolor 2430dl kept feeding paper worse every week. Sometime one had to multiple clear a virtual “Paper jam in tray 1″ to get a single sheet printer out, … with just 7563 total faces printed on the printer’s internal counters.

It got annoying enough to finally take a look, and apparently it is a known problem! And cleaning the paper pickup rubber roller really helped, for us!

Let’s print on, … :-)

dietlibc ported to mips64

Friday, February 4th, 2011

Those who know me, or other fellow readers, may have noticed: I am a little in this low-level computer science stuff, like OS kernel, assembly, ARM, PowerPC, SPARC, and such, …

So my latest pet project, for the weekend education was resurrecting the T2 MIPS port. And as such I had some fun porting dietlibc to MIPS64.

And what a fun ride that was, looking forward to see how MIPS develops on the smart-things side of life!

Call for boycott of: Sony!

Saturday, January 15th, 2011

Sony is suing computer scientist and programmer George Hotz for getting Linux to work on his personal PS3, again - performing an in-depth security analysis of the system on the way and uncovering a bunch of beginner programmer mistakes while at it.

If anyone should have sued anyone in this case, then it should have been the general public in a class action suit against Sony for taking away an formerly advertised “Other OS” feature, a function that allowed the use a real OS, such as Linux, on the “computer system” that is the PS3. A feature taken away by Sony on April the 1st 2010.

If anything, Sony should have silently taken the in-depth security analysis by Hotz and the fail0verflow group and hardened their next gen console, such as an PS4 or PSP2, with the lessons learned form all their sloppy mistakes, such as not using random data for the crypto, … [or for delivering rootkits with their Windows software, …]

I would be all for upgrading my fat PS3 that I intentionally did not update since May 2010 to still be able to boot to my Linux, and thereby save some Euro on my electricity bill due to the more efficient PS3 slim. However, Sony’s customer limiting feature removal does prevent my living room setup from going green, …

Due to Sony’s latest actions, I call to boycott Sony, until they stop suing their customers!

Instead there are plenty of other companies delivering aesthetic, feature rich, and often more affordable consumer electronic products for home entertainment and business computer equipment. Until Sony stops their latest actions against free speech, fair use and the internet I recommend supporting more customer oriented companies. Companies that do not sue their customers for doing whatever they want with the expensive equipment investment.

BREAKING: Verizon iPhone 4 w/o SIM slot?

Tuesday, January 11th, 2011

As one can (not) see in the hands on shoots of Engadget, the iPhone 4 Verizon edition apparently does no longer spot a SIM card slot, maybe actication time programmed as rumored earlier?

AMD Fusion to end Atom performance stangation

Monday, January 10th, 2011

Finally, with the CES 2011 AMD finally set free the new Fusion APUs built from the power-efficient Bobcat micro architecture. The new AMD C-50 and E-350 set off to finally end the performance stagnation that is the Intel Atom.

One certainly does not need exorbitant number crunching performance while on-the-go. However, enough performance for a snappy web browser and video playback is certainly welcome as are more than 1024×600 pixel real estate to view more than a Twitter tweet as well as to drive more than an aging VGA link on your favorite desktop to do real work.

It looks like the VIA dual-core Nano X2 will again arrive late to the party, and the more performant Bobcat will not leave much niche for VIA to play (abysmal open source 3D drivers will do it’s rest).

Cheers from my side -to booth of them- putting some real pressure on Intel, and I am desperately looking forward to sub 10W, slim & light AMD ultra portables:

Acer Aspire One 522
Acer Iconia Tablet
Fujitsu Lifebook PH50/C
Lenovo ThinkPad X120e
Hewlett Packard DM1
MSI Wind U270
MSI CR650
Sony VAIO Y
Toshiba Satellite C655D

And who knows, maybe we will eventually see AMD’s latest, greatest shipping in one or the other Apple, too …

Update: initial performance impressions!

Update 2: and another one, …

Update 3: wow, just wow, less than an inch thick Compulab PC3, with AMD Fusion Embedded G series APU

Finally, my iPhone3G is officially unlocked, yay!

Monday, September 20th, 2010

It only took 2 years for the contract to expire and endless calls to T-Mobile Germany. Unfortunately the IMEI exchange from the exclusive phone resellers to Apple is a little lazy, works by exchanging spreadsheets or even good old facsimile transmissions and does not appear to be directly database record exchange oriented.

So I had to dictate (wait what, should they not have that in their system to start with?) IMEI to a call center agent, and they pass it along to their Apple contact department, … And after the promised “unlocked in a week” had passed, nothing was unlocked and I called again: to find out that T-Mobile had not even passed it to Apple, yet. Sigh! That second person promissed “it will be activated by Friday night”, that was last Wednesday, … Of course nothing was unlocked by Friday, nor Saturday, or Sunday, … not even this morning, … but now it is!

Got some strange “session timed out” while taking the screenshot:

In case it helps someone the hyperlink pointed to:

https://albert.apple.com/WebObjects/ALUnbrick.woa/wa/default

Unfortunately calling T-Mobile is a rather annoying affair. They let you hanging in a to-be-payed-by-minute line and drop you out after some ten minutes, so I had to call them very often (like three or more times, which is over half an hour!) to actually get thru, …

Apple TV 2.0 A4 powered!

Did not even imagine to find the CPU spec of Apple’s hobby on their website, but they indeed list it: Apple A4!

Linux IEEE 802.1q VLAN the new iproute2 way

Tuesday, August 3rd, 2010

You need to add Linux system (router, server, etc.) directly onto an 802.1q VLAN trunk? Well, for one there is this old (read: deprecated) vlan, the new way is simply via iproute2’s ip:

ip link add link eth0 name eth0.1234 type vlan id 1234

As usual: just substitute the ethernet interface name, alias, and VLAN ID as needed :-)
