Real-Time in Sweden (RTiS) 2007

RTiS 2007 just took place in Västerås, Sweden. It is a biannual event where Swedish real-time research (and that really means embedded in general these days) presents new results and summarizes results from the past two years. For someone who has worked in the field for ten years, it really feels like a gathering of friends and old acquaintances. And always some fresh new faces. Due to a scheduling conflict, I was only able to make it to day one of two.

I presented a short summary of a paper I and a colleague at Virtutech wrote last year together with Ericsson and TietoEnator, on the Simics-based simulator for the Ericsson CPP system (see the publications page for 2006 and soon for 2007). I also presented the Simics tool and demoed it in the demo session. Overall, nice to be talking to the mixed academic-industrial audience.

Solaris to IBM, x86 to Apple, Power to Microsoft, and other flying pig events

The register report “IBM embraces – wtf – Sun’s Solaris across x86 server line” is a very appropriate headline for something quite surprising. The day before this happened, we discussed the announced announcement and said “nah, it can’t be about operating systems”. The idea of IBM in-sourcing Solaris for x86 just felt like the kind of thing that was in the same realm as flying pigs, freezing hells, and similar unlikely events.

Matts Today in History: The Vasa Sinks, August 10, 1628

Matts Today in History: The Vasa Sinks, August 10, 1628
is the latest installment in the very good and long-running PodCast called “Matt’s Today in History”. I really appreciate the effort going into the production of it, and the perserverance of Matt in keeping it up for more than two years.

This particular issue was interesting in two regards.

First, I suggested the topic.

Second, it featured what at least seemed like real paid advertising at the start. This is thanks to PodShow, the “media network” used to distribute this podcast. The deal behind PodShow is quite simple fo the podcaster: you get bandwitdh for free, in return for the possibility of there being advertising inserted into the audio.

The reasoning behind PodShow is nicely explained in a podcast from the Stanford Technology Ventures Entrepreneurial Thought Leaders series. Here, Ron Bloom and Ray Lane of PodShow describe the way PodShow got started and just what it is. Basically, they are building a new media company, to compete with radio and television. It is not just a nice place to find podcasts. Recommended listen for anyone interested in just how podcasting can be monetized. They describe how their staff constantly monitors the various shows that they carry, and find those popular and targeted enough to carry some paid advertising. Other shows carry intros and pointers to various other PodShow shows, to drive audience to more popular properties.

Thus, the conclusion must be that Matt’s Today in History has reached some threshold of audience that makes it valuable enough to carry advertising. Great job, and a sure sign of popularity of the podcast.

The Customer is not always Right

I just listened to Episode 103 of the Security Now podcast, where Leo Laporte and Steve Gibson talk to the head of security at PayPal. PayPal is doing the right thing right now, issuing their customers with RSA security keys. Which gives them two-factor authentication (password and security key passnumber).

But for some reason, they do not enforce the use of security keys on their customers. Even when you have obtained a security key (which is optional, weirdly enough) and said you are using it, you can still login without it doing some additional security questions. For the reason of convenience! Which basically reduces the security added to nothing, since you can still login in a traditional fashion.

Off-Topic: Tallink Customer Service to Pärnu

I just had a nice vacation in the Estonian town of Pärnu. Pärnu is a really nice little town full of summer visitors and still with lots of local character.

Getting there, however, was less pleasant than it could have been, thanks to Tallink where we booked the trip and the hotel nights in Pärnu.

When we booked the trip, they told us that there were convenient buses from Tallinn to Pärnu, and that we did not need to bring a car. They also booked us on a nice brand-new integrated hotel containing a “water land” and spa services, and being located very close to the beach. Sounded perfect.

As it turned out, some of these things fell through:

  • The buses to Pärnu left from the central bus station in Tallinn, which is not close to the docks where the ferries arrive, but rather some kilometers away. It would have been nice if this had been clear from the start. Instead, Tallink representatives and information made sound as if the buses left directly from the docks, or at least in some place very close by.
  • The staff on the ferry to Tallinn did not know about the direct local buses from the docks to the central bus station (a tip: it is bus number 2, which stops right outside of terminal D. Or walk some more and take tram number 2). They gave us confused and incorrect information as how to get to the bus station. At least they told us where the bus station was…
  • At the last minute (one day before departure) it turned out that our main hotel was overbooked and that we would be given a different hotel. After some discussions they also promised us entrance tickets to the water land in our booked hotel. However, it was not clear how this was to work out in practice. Or if our new hotel was any better or worse than the one we were booked on initially. Customer service gave the impression that all would be handled at check-in in their terminal in Stockholm.
  • When we checked in in Stockholm, we did get hotel vouchers for the replacement hotel. But for a double room, not the suite that was what they had said initially. And the check-in personell had no idea about the entrance tickets to the water land. “there is no note of that in the computer system”. We got to talk to a supervisor who told us that things should work out, wrote a note to the hotel on a copy of our booking, and had the good sense to give us a name and phone number to call would they not.
  • Once we arrive in Pärnu, the hotel that we were staying at did provide an envelope containing the tickets to the water land that we needed. The hotel was also recently renovated and very fresh (it was the St. Petersburg hotel, in a carefully renovated 16th-17th-century building in downtown Pärnu). The location was more convenient for eating out and shopping, if a bit more removed from the beach (20 minutes walk rather than five).

Thus, in the end, things worked out and we got decent value for our money. Even so, it is still annoying how Tallink handled things, especially since the fixes are mostly in precision of communication and should actually be cheaper for them to do right.

So how could Tallink have done better in our case (and quite probably in general):

  • Run their own bus shuttle from Tallink to Pärnu and other interesting destinations. They do that in Sweden, so why not in Estonia? We would have been happy to pay some extra for a bus conveniently arriving at the docks to take us straight to the destination.
  • Present correct and complete facts about each destination on the phone and on their homepage. If they refer people to the bus service to Pärnu, do provide a time-table, a map on how to get to the main bus station, and a map of the end location to help you find your hotel. After all, Tallink have local staff in Tallinn that can easily find out for you.
  • Have their customer service staff be precise and clear. In the end, things did work out and we were not cheated of our vacation. But the details like the standard of our replacement hotel, how the water land tickets would work, and similar simple things could have been clearly communicated from the start. That would have saved them lots of phone service time, and us a bunch of unnecessary annoyment and anxiety.

Finally, the main drawback of a trip of this type where you spend a night on the ferry each way is that the ferry trip takes a lot of time from the vacation. This would not be so bad if it was enjoyable time, and they are trying to give off the impression that it is kind of a luxurious experience to travel on their modern ferries to Tallinn. And mostly it is nice. Going on a ship where you can walk around and have lots of space is vastly superior to inhuman modes of transport like long-distance air travel or car trips. For the kids, having a dedicated playroom is great.

But since the length of the trip makes it necessary to eat dinner and breakfast onboard, the food is quite a important component. And here Tallink and most other Baltic ferries I have tried fall down by simply providing fairly taste-less and disappointing fare. The tradition of a grand buffet is great in principle, but something makes it so that each course is cheapened down to its simplest least tasty version. Creating a rather disappointing experience overall. And there is no indication that the a la carte restaurants are any better. So for now, you eat because you have to and not as much because you enjoy it.

Why this is the case, I don’t know. Either they think their customers do not care or cannot tell a good meal from a poor one, or they lack pride in the kitchen, or they are saving money by using the cheapest stuff they can get away with, or something else.

Let’s get started

So I have finally decided to try to write a blog of my own. Having seen the phenomenon grow over the past few years, the urge to have my own place just to write short public posts or essays on interesting things got the better of me.

I might write about anything that I find interesting, but the topic is really business and computer software, and how they interrelate. Which is sufficiently broad to let me write on almost anything
