Der Fussballguck-Fluch bleibt weiterhin bestehen. Deutschland hat gestern verdientermassen verloren, auch wenn der Schiedsrichter ein wenig einseitig gepfiffen hat. Die deutsche Nationalmannschaft kann eben kein Spiel gewinnen, bei dem ich zuschaue. Und diesmal konnte ich nicht mal abschalten, denn ich war auf beim Public Viewing in Hamburg:
Es war tolle Stimmung auf dem Gelände ... ja bis zum 0:1 fuer die Spanier ... danach hat es ein wenig nachgelassen, ein wenig sehr. 10 Minuten vor Spielende sind die Ersten gegangen. BTW: Ich wusste uebrigens auch schon, das es zu Null gegen uns ausgehen wuerde, aber das ist eine andere Geschichte. Koerpergroesse hat uebrigens bei solchen Veranstaltungen einen Nachteil: Andere enttäuschte und wahrscheinlich alkoholisierte Zuschauer raunzen einen an, wenn man von der anderen Seite in ihr blickfeld gedrueckt wird, und da sich niemand freiwillig hinter jemanden mit 1,92m stellt glauben alle das da ein Durchgang ist. PS: Ich bin mir sicher, das nach dem Fuss in Kloses Leistengegend ein kollektives Schmerzgefuehl durch die Menge ging St. Stephen's Cathedral, ViennaSaturday, June 28. 2008A new offer from Sun - or: Oracle, Sun and the costs of middleware licensesSaturday, June 28. 2008
We´ve made an interesting annoucement yesterday: An all-you-can-install bundle consiting out of license and support payed on a annual basis for Mysql and Glassfish. A really interesting offer. You should look at the website of Sun for the details.
But this isn´t the point i want to write about: I strongly believe, this move may hurt Oracle. Not because of the this offer, but because of this as a part of a more general movement in the market. We won´t lure a large amount of old installation to Mysql and Glasfish. It´s more an idea for new systems. Since the last increase of licensing costs (and this is only half the story, as the maintainance costs are based on a percentage of the license costs) i´ve read multiple comments, that customers can´t longer justify or even afford the costs for the stuff from Oracle. BTW: There is another infrastructure component that had a hefty increase in pricing. When BEA was an independent company, a processor license for Weblogic Enterprise Edition burned a $17,000 hole per processor in your pocket. Nowadays BEA is a LarryCorp and the same license costs you $25,000. Additionally Oracle is the last stronghold of the core based licensing models with somewhat strange core multipliers. Not that there is no logic behind this core multipliers, but the logic is purely in favour of LarryCorp. You can ask yourself, why a Victoria Falls Core is worth 0,75 cores but a Opteron/Intel core is worth 0.5 cores. And why a Power6 core is equivalent to a Niagara 1 core when used at 1.4 GHz? The logic is quite simple behind it: On a given IT budget less money for the hardware leaves more money for LarryCorp. Thus you give the the customer an incentive for cheap hardware, even when it would force you to Enterprise Edition much faster than a equivalent SPARC system (256 Cores VF in Batoka is still Standard Edition, an equivalent System for OLTP loads with x86 would need more than 4 sockets, thus lead you in the realm of the Enterprise Edition). Okay, at least this explains the strange factor for Intel. The favourable factor for IBM pseries is still a miracle to me. The next bluesuit after the pSeries salesperson entering your office is the salesperson for DB2, leaving nothing earn to Oracle ... Of course large databases for your ERP will stay on the established databases like Oracle. But everything else? A well-supported database may drive all this auxillary databases in a company to other systems and every increase in licence princing make the concept of having two databases in you company more alluring. With the application server it´s something different. Glassfish plays in the same technical ballpark like BEA Weblogic AppServer, thus the effects of the new "all-you-can-install" licensing model may be much more adverse for Oracle. Okay, there are interesting times ahead of us. Shrinking IT-Budgets may lead to a more sensible position to multiple, but right sized software systems. We will see the effects in the middleware sector. Ultra Dense ThumperSaturday, June 28. 2008
I had an idea for a new product this morning while waiting for boiling water for my tea: A ultra dense packed Thumper. In a X4500 you can put 48 hard disks with 1 TB worth of storage per disks, giving you 48 TB of storage. An disclaimer at first: This is not an upcoming product as far as i´m aware of and it´s only a tought game on the basis of data sheets from the websites of the usual suspects.
Okay, the casing of the X4500 has a width of 439 mm and a length of depth of 749,9 mm. Let´s assume we can´t use 10 mm of the length and 10 mm of the size. We keep the size of 4 rack units. Now let´s change a little piece of the equation: We will use 2,5 disks! A Samsung HM500LI has a width of 69,85 mm, a length of 100 mm and a height of 9,5 mm. The disks will plugged in from above like with the normal thumper. The small side will be parallel to the the front side to the casing. A 4 RU unit casing like the thumper has a height of 175 mm, the disk takes 100 mm. So we have 75 mm for the top and the bottom of the casing of the "Dense Thumper", the "system controller" and a backplane. As 1 RU (44,5m) dual socket is normal, it should be not problem to integrate the system beneath the harddisks with plain standard technology. Let´s further assume that every harddisk get´s 1,5mm additional space in the direction of the airflow and 0.5mm in the other orientation.So a disk takes 12,5mm in height and 70,85mm in width. Let´s further assume, that you need an 5 mm per disk for a simple slide-in holder (increasing the width ...something like two miniature u-profiles sliding in each other) With such dimensions you would be able to hold 38 disks on the width of the "ultra dense thumper casing" and 9 disks on the length of the casing. This leads to a total amount of disks in the casing of 342 disks. A HM500LI has 500 GB per disk, thus such a "Dense Thumper" would give you 171 Terabyte (marketing ones) of storage on 4 rack units. The whole disks would take something aroung 900 watts of power. BTW: A staggered spin-up of all these disks looks really sensible ... Connecting the all these disks to the system is a little bit tricky. But this should be solvable to. The is a chip called LSI LSISASx36. This is a 36-Port 3Gb/s SAS Expander. We use 4 connections for outside connections and 32 lanes for disk connection. Thus we have to connect 11 of this chips. This chips could connect to SAS controllers like the LSISAS1068E, an 8-Port PCI Express to 3Gb/s SAS Controller. This leads to the necessity of 6 of this controller as we can connect 2 expander to 1 controller chip. For this 6 Controller you would need 6 PCI Express busses. This should be solvable with a Opteron based system. I should write a mail to Andy ...

More news about the Netapp lawsuitFriday, June 27. 2008
There is an additional interesting read on Mikes homepage: The reply of Dave Hitz to Suns plea for a partial stay until the PTO made some decisions. Of course, you want to see an decision while your core patents are still valid when there is a good chance that they will by invaldidated by the PTO due prior art
News about the NetApp lawsuitThursday, June 26. 2008
Mike Dillon (our general counsel) posted some news about the NetApp lawsuit in his blog - NetApp Litigation - an update:
Over the last two months, the PTO has granted the first five of our reexamination requests, finding in all the cases that multiple “SNQP” exist for each patent (one request filed in June is still pending). These include, among others, US Patent Nos. 5,819,292; 6,857,001 and 6,892,211, "core patents" according to NetApp. With regard to one NetApp patent, the ‘001 patent, the PTO has issued a first action rejecting all the claims of this patent. Yet another security theaterThursday, June 26. 2008
Bruce Schneier linked to an interesting essay about mass screening of people with infrared thermometry guns. With this devices you can measure the temperature of a person from a certain disctance. But the essay questions the sense of such a method as they compared the results of this IR guns with :
We assessed the accuracy of cutaneous infrared thermometry, which measures temperature on the forehead, for detecting patients with fever in patients admitted to an emergency department. Although negative predictive value was excellent (0.99), positive predictive value was low (0.10). Therefore, we question mass detection of febrile patients by using this method.Negative predictive value means "The device says you have no fever and you have really no fever". Negative predictive value stands for "The device says you have fever, and you have really fever." So the system is good at detecting a person without fever, but not at dividing people with a higher (but normal for them) skin temperature and people with fever.

Advertisment gone badThursday, June 26. 2008
A colleague of me got a mail from a company selling virtualisation technology for a special offer. Well ... a good idea. A good advertisment is the polite offer to the customer, a seduction to buy your product. A good advertisment is polite and full of respect to the customer. So i have the vage notion that this advertisment is somewhat counter-productive

VerbaseltThursday, June 26. 2008
Bei omnisophie erklaert Gunter Dück, wie das vollstaendige Ausnutzen der Basel II-Regularien zu den Problem gefuehrt hat, deren Auswirkungen wir in Form des Bankendominos sehen:
Die Ver-Basel-Grenzen aber werden wie Empfehlungen gesehen, immer genau an der Grenze zu stehen, immer nur einen Nanometer neben der Kriminalpolizei, immer ein Milligramm vor dem Absturz in den Tod. So wird das Leben zu einem reinen Seiltanz über der Schlucht, bei dem die besseren Menschen einen Fallschirm dabei haben und die restlichen zu Präkariatsmasse zerschellen. Unten, wenn alle vom Seil fallen, warten wir Hilfsbereiten und päppeln die mit Staatsgeldern auf, die noch leben – die mit den Fallschirmen.Sehr gut geschrieben ... Sun Ray MythsThursday, June 26. 2008
The Sun Ray technology is one of really cool technolgies of Sun, but somehow it´s surrounded by some misunderstandings. Paul Murphy wrote with his artcle "The top Sun Ray myths" an interesting answer to the most prevalent myths.
