The lack of luggage

Sunday, October 28th, 2007

I had a feeling things would not be OK, when I had to check myself in. The machine gave me three leaves of paper, which did not resemble a boarding pass at all. Then I presented my luggage to a not-so-nice-lady at the counter. I showed her the sheets, and she never mentioned they would not do. But it got me through security. So everything appeared to be ok. Until I arrived at the boarding point, and I clogged the line because I could not board using the semi-boarding pass I was issued. No really. I showed the guy the itenary ticket I had received the week before when leaving Brussels. After some debate, it seemed I would be allowed to board.

I still have no idea where I should have obtained a real boarding pass. I encountered no other counters where I could have received something. My ticket was checked three four times: once when checking in my luggage, when entering the security checkpoint, when leaving it and when entering the section leading to the gate where I needed to board. So why nobody told me I could not board using it – and why they issue it in the first place – I remain clueless.

Same story at Frankfurt. Apparently, there is no money associated with such a boarding pass, and the lady flat out refused to let me board. I showed her my itenary ticket, which seemed to soothe her some. In the end, she wrote down my reservation number, and said she’d get her money that way.

Final smack was dealt in Brussels Airport. After waiting until the luggage line stopped, I lined up with some other people who were going to complain. When it finally was my turn, the lady was flabbergasted at the luggage coupon I showed her. I needed a tag from the label that was attached to my bag. Duh. No, sorry, can’t give you that, I only have this piece of paper. After some fiddling, she located some clues, and found out my bag was still waiting in Montreal. Now, I hope she was right, and my bag is not kind of lost. After all, it’s filled to the brim with presents for my kids and for Veerle.

Bottom line, I should have refused when Lufthansa changed my return itenary from the LH flight leaving at 17:10 to the one operated by Air Canada leaving at 19:40.

Update: I have received my luggage on Monday evening, when a friendly French-speaking guy rang my bell and required me to sign off on the bag he dropped on my porch.

Travelling to Montreal

Sunday, October 21st, 2007

The flight was very uneventful. Luckily. Unlike the last flight I took with British Airways, Lufthansa managed to get us flying on schedule. The food on board was quite good, actually. I took the chicken, which seemed to have been killed prematurely, because apparently, there was very little meat available. The only drawback was the lack of sufficient drinks. Refusing one kind of juice results in the stewardess passing us by on the second round, rather than offering us water.

From the air, Montreal looks spectacular. There are trees lined up on each sidewalk, wich gives a superb effect as the leaves are coloured in various shades of green, yellow and brown.

Manipulation

Monday, October 2nd, 2006

The NMBS (Belgian railways) keeps track of the delays each vehicle has. They use it to produce annual reports on the preciseness of their service. The aim is to keep delays to a minimum. However, I was told that, as long as the announced delay does not equal or exceed 10 minutes, they delay is dropped from the statistics.

I’ve been commuting between Ghent and Ostend for the past ten years, and it is quite rare that they use delays that are not a multiple of five minutes. So, perhaps this was a neat way to improve, shall we say, the annual report :-)


Manipulation?

Return Trip

Saturday, September 23rd, 2006

We had slightly hoped that the return trip from Seattle would proceed as planned. And it did. More or less. We did not miss any plane, and we arrived in Brussels with all of our bags. But. The check-in counters of BA in Seattle were rather undermanned. The line was long, and the time was running short. Finally BA decided to allow economy class travellers at their first and business class counters (though they call it slightly different IIRC). With less than an hour to reach the gate, the check-in line began moving faster. No windows seats left (obviously), and we were at the very rear of the plane, on what they claimed were pre-assigned seats. Ah well. We moved on to the security line, with abut 35 to 40 minutes before the deadline the check-in lady gave us to reach the gate. I wonder how the line behind us could possibly make that deadline. Lucky for us the security check went speedily. Some people were confused about the no-belts, no-shoes demand, but we passed through ok. No re-checks.

When we made it to the gate, having just missed the train – causing an extra 4 minute delay – we were asked if we’d passed the immigration machines. Nope. Seems weird, checking out of the US is obligatory, and we thought we were doing fine because they had removed the immigration paper from the passport when checking in, but apparently there is nobody forcing you to pass the US-visit machines to have your prints taken once more. When they announced it at the gate prior to boarding, a lot of people were getting up and moving out fast to the said machine.

The flight itself was uneventful, I watched MI-III, which was good, brainless entertainment. Nothing spectacular and certainly not as good as I and II. The ride was bumpy at times, but no booze was spilled. The dude serving us was not very friendly, and the chick in front of me got angry when I stowed away my powerbook and (reading) book in the seat, bumping into her back. I managed to sleep through most of the night. We landed half an hour late. This gave us max. 1.5 hours to reach the next gate. Great. Heathrow made our plane wait for another half hour on the runway, which was even greater. Add to that the fact that we needed to stay in Terminal 4, passing the same security line we passed on our outbound trip, and you can see that there was a good reason for an increase in stress. Additionally, we had seats on row 51. The back of the plane. With 55 minutes to reach the gate, people began to move at the business class. Luckily, some people stayed seated, so we could moved on faster than expected. We also did manage to walk by most of the passengers of our plane on the way to the security check. So, we finally made it with 15 minutes to spare to the gate. Sigh.

In Brussels, both bags turned up on the carroussel, so we went on our happy way, trying out the Belgian railways. Luckily, we managed ok. No delays.

PACT paper

Tuesday, September 19th, 2006

I am a co-author for a paper accepted at PACT 2006, titled “Performance Prediction based on Inherent Program Similarity”, by K. Hoste, A. Phansalkar, L. Eeckhout, A. Georges, L.K. John and K. De Bosschere. Kenneth Hoste will present it tomorrow.

The paper abstract reads as follows.

A key challenge in benchmarking is to predict the performance of an application of interest on a number of platforms in order to determine which platform yields the best performance. This paper proposes an approach for doing this.
We measure a number of microarchitecture-independent characteristics from the application of interest, and relate these characteristics to the characteristics of the programs from a previously profiled benchmark suite. Based on the similarity of the application of interest with programs in the benchmark suite, we make a performance prediction of the application of interest.
We propose and evaluate three approaches (normalization, principal components analysis and genetic algorithm) to transform the raw data set of microarchitecture-independent characteristics into a benchmark space in which the relative distance is a measure for the relative performance differences.
We evaluate our approach using all of the SPEC CPU2000 benchmarks and real hardware performance numbers from the SPEC website. Our framework estimates per-benchmark machine ranks with a 0.89 average and a 0.80 worst case rank correlation coefficient.

We show that it is possible to make a very good prediction of which machine will be the best performing machine for an application of which we know only the microarchitecture independent characteristics. You can find a pdf of the paper here.

Seattle

Sunday, September 17th, 2006

I am in Seattle for PACT, where a paper I am co-author of, will be presented by Kenneth. The trip over here was smooth in some aspects, bumpy in others.

First of all, let me say that the airline food on the BA flight was nothing short of good. The most yummy food I’ve ever gobbled down when flying. The chicken came with a nice mushroom sauce, the potatoes were edible, and the vegetables were yummy. The dinner was very good as well, though I did not eat it all. While the British in general can’t cook, they do make the greatest cakes.

Inflight entertainment was good too, with nice screen for everybody, and a rich choice of programs to watch. I viewed The Da Vinci Code, and the second half of X-Men II: The Last Stand. I drained my PowerBook battery trying to get some work done, and had a bit of a nap.

Now on to the bad parts. The flight from Brussels to Heathrow arrived late, and we were delivered to the wrong gate, so we had to wait for a bus to take us back to a gate where we were allowed to arrive. It seems strange to me, but apparently, the Brits are not allowed to disembark at a terminal where people will embark subsequently. To me, it seems like one just needs two levels at the terminal, but they seemed not to have thought of that. So, after a wait and a ride (including a stop to remove some bag, that had fallen from a lorry, from the road) we were finally ready to make our way from Terminal building 4 to Terminal building 4, which seemed to include a thorough security check. I knew that fluids were not allowed, but they made me remove the spare ink cartridges I had with me. Even the attendant though it was simply ridiculous. By then, we had about 40 minutes left of the two hours we originally had according to our travel plan to get to the gate for boarding the seattle flight. Twenty minutes later, having moved on about 20 metres in the row, we asked some official looking girl what to do. One minute later, another official looking girl passed by, towing a load of passengers needing to get their connection. We joined the passenger train and were brought to the front of the line, where they made us take off our shoes, belt, take out our laptop, picked out an old man for screening, … By then it was 15:45, and the gate closed at 15:55, or so our boarding pass mentioned. Needless to say, we took the rest of the way to the gate at an increased pace. I did not dare to run, remembering the Brazilian student police shot a while ago. But we made it on time to the gate. Obviously, as the boarding got delayed to 10 minutes past the foreseen take-off time.

That, however was not the end of trouble. Upon arrival in Seattle, we were last through immigration, joining the group still waiting for their luggage. As more bags rolled onto the carroussel, and ours were not with it, our agitation increased. Slightly. But when the man who set the luggage upright at the carroussel walked away, a mild panic surged over us. I was more than relieved when my bag appeared. But Kenneth went half beserk when his did not. To make a long story short, we waited some more, went to see the lady form BA, got send through customs, onto the main bagage claim floor, where left-over bags seemed to have been directed. Nothing there, went to see the BA bagage people, where they told us the bag was still in London. Really. It should arrive today, they said, and gave us $50 to buy some stuff.

So far the first day in Seattle. We did find some good food in Rock Bottom, just around the corner from our Hotel.
