Is light-gray-blue a good color

Sunday, March 16, 2003 22:42 // Aarburg, Switzerland // href

In 14 days we will be moving out of our good old flat, to a new house. Or rather we will move out, and after Easter we will move into the new house.

Yesterday we finally chose the new table and chairs we were going to buy for the house. We spent a great deal of time figuring out what table we were going to get and where we would get it without spending all the money we have left after buying that house.

What we sort of ignored all the time, was the chairs. We did not ignore them completely, no, but we did never discuss their color. So when we finally were ready to order everything, yesterday at the furniture place, the guy wanted to know which color the chairs should be (the part which is not wood).

We have a pitch black floor, a fair beech wood table, white walls, transparent light gray white curtains. The chairs should contrast to their surroundings without taking all the attention. Aargh ... what a decision 20 minutes before they are going to close the shop for the night.

We went back and forth amongst all the colors on offer and finally settled on a fair grayish color with a hint of blue. With the order sent and the price agreed, we are left to worry if this was really the color which is right for us. Will not be to delicate? Will it fit with the rest of our furniture? I see six to eight weeks of worrying to worry ahead of us. Because of all our special wishes, it will take them that long to produce and ship the things.

Don't say it ... just don't! I'm going to bed now.

 

75 billion for the war

Monday, March 24, 2003 23:48 // Home Sweet Home, Aarburg, Switzerland // href

I read in the paper today that the George W is going to ask Congress for 75 billion to finance his crusade against Saddam. Lets assume this will amount to about to maybe 100 billion in the end. This is about 500$ for each American citizen or 5,000$ for each person living in Iraq. I don't know how much the average income in Iraq is, but I guess with 5,000$ per person you should do well. Think even how many people in some other 3rd world country, one which has not even oil, could be sustained with this kind of money.

I saw Bowling for Columbine (www.amazon.com ...) last autumn, today heard Michael Moore's (www.michaelmoore.com ...) acceptance speech for the Oscar. He seems to be one of the few outspoken, witty Americans around these days, who are actively working for a better future for America in this world and not apart from it. A country currently governed by fear and through fear of an artificially enhanced enemy whom to fight will serve as a method to ensure W's reelection by people who might otherwise just realize what disservice they are doing themselves by choosing leaders who don't seem to have the understanding nor the intention to play by the rules for the greater good of the world.

In the radio news today, the presenter remarked, that the US was detaining POWs in Guantanamo under the label of 'Unlawful Combatants', refusing them any of the rights POWs should have, according to international law. He continued, that Iraq might call the US Soldiers exactly the same and would not even be all the out of line as the US is fighting this war with out UN mandate and is thus in blatant violation of the very fabric the chances for stability and prosperity of the world are based upon.

 

4 vans full of stuff and lots of help

Sunday, March 30, 2003 17:31 // Feldstrasse to Aarweg, Olten // href

All Friday Regula have been packing our stuff into cardboard boxes. On Saturday morning at 8:30 10 of our friends arrived in Aarburg, ready to help us move all our belongings from the flat at the Feldstrasse to our new house at the Aarweg in Olten.

We had packed 90 boxes which had to be carried down 3 floors at the old place and up 4 floors in the new place. And this was only the beginning. The boxes alone filled the Van we had rented. A further three rides were necessary to transport all our furniture. I had hoped we would manage with two rides. I was so wrong. I promise, I will never buy anything new unless I give something old away ...

At 4pm all was done and everybody had had a gracious share of lifting and stair climbing. Thanks to the delicious lunch my mother had prepared for the whole crew we were tired, but at least well fed. (Thanks Mom!)

A big thanks to Alexa, Claudia, Doris, Gabi, Regula, Christoph, David, Fritz, Manfred, Manuel for their help. If you are ever going to move house, count me in.

 

War on Iraq proposed by Clinton

Monday, April 07, 2003 23:53 // Gallusstrasse, Olten, Switzerland // href

I was searching google groups today when I lumbered onto this post from February 1998: (groups.google.com ...)

Amazing, these days many people blame W but six years ago, the Clinton administration has proposed a war on Iraq as well, only that they did listen: (www.cnn.com ...) It seems CNN has not edited their archives, even thought these days, US media don't report anti war rallies unless many hundred thousends attend. They rather bring an extendes feature on the few people marching for the war. It seems that independent and critical journalism is "out". Remember Watergate?

Today Akamai kicked Al Jazeera off their network. The Register has some thoughts on this (www.theregister.co.uk ...)

 

First Meeting of the SANE 2004 Program Committee

I got up at 4:15 am today. In order to get to Eindhoven on time, I had to take the 7 am flight from Zurich and thus the 5:20 train from Olten. Guess I am lucky to have no problem with getting up early.

In Schiphol I met Rudi and Alexios. Together we rode to Eindhoven and arrived at the TU/e just in time for the meeting. The other members of the program committee were there as well: Walter, Edwin, Brenda, Peter, Bastiaan, Xander, Jos and Fred. And there was also Marielle and Sabina from Iconic who will be doing all the actual organization work for the conference.

This is my first time on a PC. What I found the most difficult part, is to figure out which talks would be relevant 1.5 years from now, as the conference will be held at the end of September 2004.

At the meeting we did not really decide anything fixed, apart from the meaning of SANE: System Administation and Network Engineering Conference.

We tossed around a ton of names of potential invited speakers, had a short discussion about the deadlines, debated whether we should demand 400 word abstracts or extended abstracts like LISA. We also collected places where we wanted to distribute the Call for Papers.

I guess most things will get sorted on our PC mailing list, as we move on.

 

How to become a virus expert

Sunday, August 24, 2003 22:33 // ETH Zurich // href

eye candy

A week ago, a journalist of the swiss NZZ Newspaper had been directed to me by the universities press office. The guy was looking at writing a story on Open Source software and the press office people knew I had some projects in this area. It was the week of the Blaster worm. So after talking for about 40 minutes to the journalist on Wednesday he calls on Thursday to let me know that the story on Open Source had been shelfed, and he had to write a piece on Blaster. Oh, and by the way, would I know anything about the worm. I had been battling it for the last two days, so I said yes. With the effect that I was quoted in the article on Blaster.

The following week a guy from Swiss national television (SF DRS) called, they were doing a piece on Blaster too, with a 'confront MS angle'. They had read my name in the newspaper, I agreed to the interview. I organized coaching from our press office, as the TV people were from that hard hitting investigative show, and I didn't want to be caught in the middle. I was really careful not to make any too harsh comments. They have not yet broadcast it, so I don't know if I am going to look good or bad.

In the meantime Sobig has come back to haunt us, now in its F incarnation. The press office sent the local TV people straight to me when they inquired about a person to talk to regarding Sobig.

As you can see in the screenshot, I am the IT expert now. I picked that profession after the TV people told me that "Systemmanager" was way too complex and the press office people insisted, that "Security Specialist" was going to cause trouble with the folks from CS or central IT Security. Just in case you ever wondered how you become an expert.

I guess I just had my 15 minutes of fame :-).

 

Today I watched Farscape ep 22 season 4

Friday, September 12, 2003 20:42 // Olten, Earth // href

I have known it for a about a year. SciFi has not renewed its commitment to Farscape which essentially meant the end of the show. I am sure none of the folks at SciFi who made these decisions had watched the show. How else could it be that they killed the single most captivating, intelligent, humorous, sexy, thrilling, emotional and realistic sci-fi show ever conceived. Almost every episode I watched left me tingling all over, ideally wondering how they were able to come up with these great episodes over and over again.

It's almost a year since the cancellation, the Farscape fan-base still seems to be going strong at (www.savefarscape.co ...) plotting away on a strategy to get the show back on the air. Never loose hope.

Today I also went to the website of SciFi wondering what they were doing regarding Farscape. And indeed, they have this page "Farscape Memories" with articles from different actors remembering their time shooting the series. What hypocrisy first they pull the plug on the show and then they act all bleary eyed.

If I was rich, I mean real rich, I would just order a few more years of Farscape from the Creature Shop ... I guess I should not have gone into OpenSource, but rather have turned commercial at an early age, sucking in big bucks during the Internet Bubble then I could do more than keeping my fingers crossed for another network picking up the show again.

 

Wilbur, Alice and a Friend of mine

Tuesday, December 09, 2003 22:06 // Arthouse Alba, Zurich, Switzerland // href

The other night I went to see "Wilbur wants to kill himself" (xrl.us ...) a movie about a guy, his brother, a women kid living in some Scottish town. The guy has a book shop, falls in love with the women and the brother tried to kill himself. The movie is by Lone Scherfig a Danish writer/director who was quite successful with the movie Italian for Beginners. I loved the story and the acting and above all the Scottish accent.

The strangest thing happened to me a few minutes into the film. When Alice (the women) entered the scene for the first time. She looks exactly like a friend of mine. I am quite sure it was not here, because she does not speak with a Scottish accent, and she is not an actress. Never the less I kept comparing her and Alice all through out the film. How would she act in a similar situation? And just to make it more complex, Alice is just a role, played by Shirley Henderson (xrl.us ...) but written by Sherfig, so how can it have any bearing on my friends behavior, or do looks influence how people behave, did Sherfig write the part of Alice for Shirley? Are Alice and my friend twins separated a birth?

Well it was a wired experience, but definitely a great movie. Go watch it!

 

The West Wing and reality

Tuesday, December 09, 2003 22:36 // Aarweg, Olten, Switzerland // href

I admit, I am a soap opera junkie. I just love watching them. My current favorite is The West Wing written by Aaron Sorkin (en2.wikipedia.org ...). Tonight I made it through the final episode of the first season. This time the outlook is great, as the show is till running in the US, now in its fifth season.

The West Wing is about people working in the White House for the President. It's also about the President himself. President Bartlet, played by Martin Sheen is a liberal Democrats dream. What a contrast to the current reality. An American friend told me recently that she finds it rather disturbing to watch the show, seeing what the reality could also be. Michael Moor even nominates Bartlet for President, along with Oprah in his latest book.

I am watching the West Wing on DVD, there was also the 15 minutes Making Of feature on one of the disk. There the actors talk about their parts and some bits of the sets are shown. Hearing the actors talk was odd. They were so different from the roles they play in the show. Not only did they talk differently, but also their body language was altered. I have never noticed something like this before in such a show. The characters in the West Wing make a very authentic impression on me, much more than the actors themselves actually. At least as far as the story line and the dialogs are concerned this has to be credited to Aaron Sorkin. Maybe Michael Moor should be nominating Aron Sorkin along with Oprah and Bartlet, someone has to write their lines after all.

 

Finding Needles in a TB Haystack.

A Talk by Urs Hölzel, Vice President for Technology,

About Google

Mission: TO organize the worlds information and make it universally accessible and useful,

An international company: 250% traffic from outside US

Engine has 4 Billion pages in index

Profitable since q1/2001

23 Office Location Worldwide.

15k boxes, several TB disk storage

There are over 1000 queries a seconds on dec 25th, 2am.

About the Web

Static web 167 TB in 11 Giga Pages, but dynamic websize 92 PB. (Estimates)

1 in 4 hosts on the net run a webserver.

Problem: All data, users, hosts grow exponentially. This means the problem of finding useful information grows exponentially too which makes for interesting problems.

Google Infrastructure

A high reliable system based on low cost comodity hardware. Redundancy has to be built into the software and hardware. Monitoring, repair and maintain these boxes is a prime problem.

The Google Filesystem GFS

Stripe files across many boxes and replicate them on multiple servers.

Components: Master - keeps directory and plans file layout, ChunkServer - hold the data. Clients - use the data. (Chunksize is 64 MB. Data is cached on client once retrieved. SOSP'03 (www.cs.rochester.edu ...) )

10+ Clusters of 1000+ boxes.

How to be a Search Engine

Crawling: Recursive Process. Problem: dynamic pages, slow servers, management of the link list, session ids in the URL, how to prioritize the URLs, being nice to the web servers, detection of duplicates, avoiding traps, actively fill forms to pull "hidden" contents, figure out when the page needs to be re-crawled.

Indexing: Words by document and position in the document. One Terra Words in the index.

Ranking: Hard problem. All traditional assumptions on searching like long, coherent, high quality documents are not valid for web documents. Googles idea is to define a PageRank for figuring the importance of the page. The PageRank of a page is the sum of PageRanks of other pages pointing to this page. A page contributes its PageRank divided by number of out-links to each of its target pages. In reality it is more complex. Google has about 100 factors in its real PageRank function like font size, color, proximity to other words.

Serving: Partition the data to different servers and have each solve a sub problem of each query. Query goes to Google Webserver, it queries Index Farm, accesses the Doc Farm for the real data. Additional services from Add Server and Spelling Server. IEEE Micro, 2003 has more on the structure (www.computer.org ...) .

Advertising: Find the best add, relevant to the query. This is a very important problem as this is the main source of revenue. Only show an add which has a chance to be clicked on, if the click-through is low, the add will be dropped. Advertisers only pay for adds actually clicked.

Google Playground

There is lots of data and computing infrastructure at Google. Google pays people who spend their time on figuring new ways to analyze and present this data: (labs.google.co ...)
