TortoiseSVN+SSH: ”Can’t create tunnel:” – Correct settings?


Yesterday it worked like a charm. Today I get ”Can’t create tunnel”.

This time the solution was to go to TortoiseSVN settings -> Network and make sure that SSH client is set to ”C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe”.

I wonder why that setting went astray.

Still not getting svn+ssh to work in cygwin though…

En dag för några citat om livet och sån’t


Utöver att att skrivit flertalet bra essäer, så har Paul Graham lagt upp flera citat. Eftersom jag behövde några just nu så bjussar jag på mina fyra favoriter för dagen:

”The key to performance is elegance, not battalions of special cases.”
– Jon Bentley and Doug McIlroy

”Dealing with failure is easy: Work hard to improve. Success is also easy to handle: You’ve solved the wrong problem. Work hard to improve.”
– Alan Perlis

”Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.”
– Mark Twain

”We act as though comfort and luxury were the chief requirements of life, when all that we need to make us happy is something to be enthusiastic about.”
– Einstein

Personal pedagogical ideas about undergraduate and postgraduate teaching


Remembered that I had some thoughts written down…

I can teach whatever I choose, but unless the students choose to learn, it will be in vain. Hence I believe that the focus be must be upon learning and not teaching. To most, motivation and interest are necessary for learning and with motivated students, pretty much anything is possible. The necessary motivation can be ”created” in several ways. Obviously relevant examination and grading is important, but more so is putting the knowledge in a context, and creating a percieved value in the course contents.

To accomplish the above, new knowledge must be related to knowledge the students already have. An island of knowledge is useless unless there is a bridge to it. If this bridge exists, and the application of the skill is obvious and/or needed, motivation comes so much easier. The capability to put one self in the students shoes and see the world from their perspective makes this very process so much easier.

Even more important than the actual knowledge gained – at least for the last years of the master program – is that the students really learn to learn. I think that we – the teachers and supervisors – have a huge responsibility there. It is we who will create the expectations and act as a good example. It is tempting to take the easy way out, but showing the answer or the solution is seldom the right thing to do. What we need to focus on is to learn the students how to figure out where to start looking for the solution and what information is required to be able to start the problem solving process.

Generally, students at KTH have typically only a very limited knowledge of ethics, morals, philosophy, science history, and the associated responsibility that we as engineers and fellow humans have. Because of this, many student have a hard time understanding and appreciating what technology really means and how it affects society as a whole. We – the engineers –  are part in the creation of the future. The choices we do, the engineering knowledge, designs, applications, and solutions we create will have a major influence on where the world will go. It is my opinion, that there is room in the curriculum to address some of these issues. I believe that would create even better engineers.

We should make sure that the students that get their exams are truly proud to be engineers. If we succeed in doing this, we can be proud to be part of the system that makes that happen.

Android, iPhone eller inte…


Jag är ju sjukt nöjd med min yttepyttelilla och fantastiskt enkla Samsung. Det var ett steg tillbaka från min gamla telefon som var specmässigt bättre på alla sätt. Men man vill ju alltid har mer: bra kamera, 3G, wlan, surfmöjligheter, appar… Eller så vill man inte det?

MP3 and iPod in your old Renault


Especially with a CD-player that is not to fond of cold weather, playing podcasts and my favourite albums in the car without burning them to a CD would be nice. I’ve spent way too many hours looking for a solution that is cost efficient. Had I billed for those hours instead…🙂 I didn’t really find any good info in my first Google sessions so hopefully this post will aid those in need.

This won’t work for all factory Renault stereos, but it will for some. I’ve got an old Megane with the ”Update List” main unit. There is the fancy way, which is required if you want the stalk adapter to control the iPod.

But there is a simple alternative that will give you an aux input (3.5 mm stereo jack plug) in which you can connect any smartphone, iPod or whatever. The schematics are available on the internet, but bying the parts can be costly and/hard to find. Luckily in this day and age, you can find exactly what you want with some luck.

I got my cable for €16 from this site. From order to delivery in a little more than a week without any problems. Thank you! But they’re also on e-bay (search for MP3 lead for renault update list radio)

Then remove the main unit (using four precision screwdrivers or whatever in the holes) and plug the connector in. You don’t even have to disconnect the unit. Make sure the AUX input is enabled in the expert settings.

I drilled two holes in the ”pocket” below the unit. One large in which I could pull the cable and one small. A zip-tie through the two holes fix the cable to avoid pulling directly on the connector. The holes are hidden so it looks great and my aux input is now easily accessible.
