This blog will be mainly focused on my own experiences with computers and software. Both I am using now purely as a user and hobbyist. Also I comment on interesting news about ICT, privacy and combinations of both. In deze blog zal het voornamelijk gaan over ervaringen met computers en software waar ik tegenwoordig alleen nog hobbymatig mee bezig ben en mijn commentaar op imo interessante nieuwsberichten op het gebied van ICT, privacy en de combinatie van beide.

HP parks Airbus supers in containers

According to a story from The Register HP delivered two 40 footer containers with a whopping 24,192 core High Performance Cluster to Airbus Industries. The system ranks 29th on the June 2011 Top 500 list of HPC's. It makes you wonder why on earth you would change HP into a services corporation while they still perform very well in the server business.

Oracle may "fork itself" with recent MySQL moves

Ars Technica has an opinion article about the way Oracle is moving with MySQL. With commercial only options, support contracts raised from $650 to $2000 it undoubtly makes more money but kills the OSS community around MySQL. Something Larry promised not to do in negotiatons with the EU. He will come away with it because small startups forked MySQL succesfully so it ain't dead yet. I personally think the great winner will be PostgreSQL because of the technical superiority and because it is still OSS.

Kal-El Has Five Cores, Not Four: NVIDIA Reveals the Companion Core

AnandTech reports about the next generation ARM SoC from NVidia nicknamed Kal-El which most likely will be base of the Tecra 3 platform. What takes most attention is the design of 4+1 processor core the so-called companion core. This fifth core is a low power one and the processor will switch from four high performance cores to this low power core in idle state by gating the high performance one's. A nice design which helps the power consumption at a affordable rate when idling. It is also a sign of the diverse landscape of ARM processors sharing the core logic but resulting in very different SoC's.

$1,279-per-hour, 30,000-core cluster built on Amazon EC2 cloud

Ars Technica reports about using the cloud which is in this case Amazon EC to run a 30.000 node cluster. Spreaded across different zones and running voor about 7 hours costing a $1,279 per hour it shows the power of the cloud at it's best. Of course using a cluster is particular interesting for computing jobs which can be parallelized but none the less using the cloud should be a lot cheaper then an inhouse cluster. Ironically it is like the old fashioned mainframe on which you rented computercycles in minutes, long time ago. Which reminds to Ecclesiastes 1:9 The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun. 10 Is there any thing whereof it may be said, See, this is new? it hath been already of old time, which was before us.

Off-the-shelf servers spar with million-dollar storage arrays

Commoditization of storage arrays by use of off the shelf servers is coming to town.The Register has the story about VMworld 2011 where in a hands on lab three contenders were competing with their storage arrays. Well known vendors EMC and NetApp against Nexenta who build a storage array based on common of the shelf server parts for a fraction of the costs. EMC and NetApp are of course not happy with it but the message is clear: adapt or die.

Intel preps 15-Watt 'Sandy Bridge' for micro servers

Unlike AMD Intel has deep pockets for R&D. The Register reports that Intel developed a new Sandy Bridge variant with a low 15W TDP especially for microservers which are suitable for dedicated hosting and Web infrastructure workloads. Those still growing niche amount for 10% of the server market and is the target of some ARM-based servermakers like Calxeda. Intel is not giving up without a fight and those ARM-server will have to be decent priced and have better cycles/per watt performance to stay ahead of Intel. Fair competition is fine, only problem is Intel did not really like [b]fair[/b] competition in the past.

AMD snags Guinness World Record for clockiest chip

In not dead yet The Register reports the worldrecord fastest chip for AMD. They clocked a prerelease eight-core AMD FX desktop processor to 8.429GHz which is a amazing speed of course. But they can not beat Intel's current line of Core i processors and their marketshare is too little and they earn too little to continue financing the R&D effort to beat Intel. Collaboration with ARM would be a far better option especially to develope energy saving chips but it is not likely to happen.

9/11: The day we lost our privacy and power

The Register has a topic about the changed zeitgeist after 9/11 and the immense grow of the military industrial complex. The start of a era where our privacy has been shattered to dust and the Fourth World War started without being seen other then invasive measures on airfields and planes. That is to say the topic shows some buildings which are supposed to be part of the new infrastructure of the Global War On Terror. Why supposed to be? Because it is quite possible that even this article has some misinformation to misguide the "bad" guys.

How to surf T-Mobile without a data plan

ExtremeTech has a report about Smozzy an app for android phones which enables websurfing over sms/mms. Of course it is slow and Smozzy is based on a cheap VPS so it will not be able to service hundreds of phones. And it is only usefull for people with a unlimited sms/mms plan like T-Mobile USA. All in all it is a nice hack which also shows that pricing of sms/mms is highly overpriced comparing it to other datatraffic by gprs/3G. It is also reminds me to the use of 16 Kb D-channel from a ISDN connection which is capable of X25 datapacket switching but only meant to be used for signaling. If you were lucky you could use it between two locations as a low permanent datachannel for free. Most of the time they killed it after discovery with the message that they would restore it after paying an additional monthly fee.

Wikileaked cable: AFACT was MPAA’s cat’s-paw

If you ever asked yourself how far the tentacles of the American movie industry reaches you find an answer in a report from The Register. They mentions a Wikileaks cable which confirms that it was the MPAA and only in name AFACT who is sueing Australian provider Iinet about copyright infringments by their customers. Their objectives are known too they want a judgement which would be usable in all Commonwealth countries. To be continued because this case is not over yet.

Security breach at kernel.org

The Linux Kernel Archives reports a security breach in their kernel.org servers which have endured a period of about 14 days. Damage seem to be limited but are investigated further at the moment. It is quite disturbing that such a important website has been hacked so easily but it is once again a reminder of the 11th Commandment: Thou shalt make backups!
