Installing Ubuntu 12.10 on a Macbook Air

After reading pages up and down about rEFIt, and efi-grub, and how you have to resort to the command line to install debian on a Macbook, I just installed Ubuntu 12.10 almost exactly as if I was installing on a Windows laptop. I opted to keep the Mac OS partition to be able to install firmware upgrades and have a backup, but you can also choose to wipe all:

1. Shrink the Mac OS partition with the Mac OS X disk tool found in Application > Tools > Disk tools (or something to that effect): It doesn’t look like live shrinking is possible, but you have to choose the physical disk, click on “partitions”, and then add a partition. I “added” free space. In my case I was not successfull shrinking unless I gave the Mac OS partition at least as much free space as it had in use (it used about 29 GB, and I could not shrink it to less than 60.
2. Insert your USB stick with the Ubuntu install on (follow guides on how to make a USB install medium).
3. Reboot holding down the “alt” key on the keyboard and choose your USB partition to boot from.
4. Choose to install, follow the install guide, reboot and enjoy your new Ubuntu install!

After installation it did not finish shutdown properly, it had no problem booting again after that though.

Default OS will be Ubuntu, but you can choose Mac OS by holding in “alt” at startup.

Most hardware (including wireless) seems to work fine, but there are probably tweaks to apply, such as SSD optimizations and buttons ([alt]+[F4] to close windows don’t seem to work).

Logo for you sir! – First logo using 99designs.com

Some weeks ago I ended my first logo-browsing marathon on a site called 99designs.com.

99designs is an internet design “crowdsourcing” platform for hosting design contests. You post a design brief about what you want designs, choose a prize (from 99 USD and up, depending on what you want designed), and designers from all over the world post their complete design entries. I held my first contest for my employer, Western Norway Research Institute.

While I did get some valuable tip from a couple of articles (exratione.com, quixey.com) that I read before starting the contest, I had unanswered questions, that I now can answer and share with you, some of them repeat what the linked articles says:

I’ve also suggested some improvements to 99designs, that you can vote on at uservoice.

And lastly: here’s the logo that won the competition:

The easiest way to preserve your apple juice, or a really easy way to make cider

Drink! Photo: Brendan McMahan.

1. Buy a pressure cask from Speidel, or use similar cask that can tolerate 10 bar pressure.
2. Add freshly made, clean, uncontaminated apple juice made with really clean ingredients and tools. Seal cask.
3. Place in a room of about 20 degrees Celsius temperature, and make sure pressure goes up. When the pressure has reached about 5 bars you can move it to a colder room, but it should eventually (within a month or so) reach 9-12 bars.
4. Leave for about nine months.
5. Enjoy your very low alcohol, sweet, clear, sparkling cider!

Sigmund Freud died more than 70 years ago – books take on new life 70 years after their author die

Sigmund Freud died on 23rd of September 1939, 71 years ago today. But his works already entered the public domain on the 1st of January 2010.

“Sigmund Freud” by One From RM, some rights reserved.

I was going to share ‘Parapraxes’ from Introductory Lectures on Psycho-analysis (1916-1917), because it is part of my Science and Technology curriculum at NTNU, Trondheim. The other evening though, it dawned upon me that the English works of Freud probably haven’t been made freely available yet, because most of the Freud translators lived much longer than Freud himself.

So, instead of giving Freud new life on my blog, I’ll thank Project Gutenberg for Dream Psychology, point to a digital ‘Parapraxes’ that probably isn’t in the public domain, and let you know that if you want to help Project Gutenberg, the easiest way is to join Distributed proofreaders.

VPN using SSH and Firefox (SOCKS5) to surf through your university or work network

Most Norwegian students are fortunate to have access to a wealth of academic information through their univeristy network. This includes dictionaries, e-books and journals.

As a student at NTNU I also have this access, but as I’m almost never actually on campus i need an easy way to access them outside the university campus.

What follows is an easy way to access your university or work network and browse the internet through it using OpenSSH and Firefox. It can also be used as a weak proxy solution. You will have to have SSH access to your the network you want to browse through.

This is meant for you fortunate people who use Ubuntu Linux or a similar Linux distribution. If you’re a Windows user, you can see my Buzz post about the topic for instructions.

Establish your VPN

1. Open a terminal window. Type in: ssh -D 9999 ntnu-username@login.stud.ntnu.no
   (9999 is the port Firefox is connecting to, other available ports may be used.)
   Replace “ntnu-username” with your own username.
2. [Enter]
3. Type in your password and push [Enter]
4. Let the terminal window stay open. ssh should be running as long as you need your VPN.

Configure Firefox

1. Start Firefox
2. Go to Edit > Settings > Advanced > Network > Settings
3. Choose “Manual proxy settings”
4. In the field for SOCKS you write: localhost
5. In the field for port to the right you write: 9999
6. Ok, save, and so on. Now you should be set to surf through your VPN. Only in Firefox though.
7. Good luck! Remember that if the VPN channel isn’t active, you wont be able to browse the internet in Firefox without reversing the changes you did to the connection settings.

Understanding the Fjord1 time tables

Having worked in the middle of tourism in Sogn og Fjordane county (I managed a regional destination company for about a year) and receiving many couchsurfers coming by public transport, I often get to share the frustrating task of deciphering the time tables of Fjord1. I have thus found it useful to make an explanation of the codes used.

So if you ever are so fortunate to visit our beautiful fjords, glaciers and mountains, and would like to do so without your own means of transportation, you might find this explanation useful.

S: School days, which means: Monday to Friday from roughly the middle of August till the middle of June, except public holidays and school holidays. School holidays are hard to find out about and could vary from municipality to municipality. To find out about them, you could search for “skulerute” and the name of the municipality.

D: Daily
* / ** / *** / A / e: Look for explanations, will usually make limitations in time. Remember to combine all limitations.

1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday, 7 = Sunday

H = Sunday and public holidays

X = Except

DX3 thus means every day except Wednesdays. Public holidays have their own time tables and are thus always excempt. Usually timetables for public holidays will be the same as for Sundays.

Oh, and there is an online service for the timetables. Try ruteinfo.net or rutebok.no.

If you understand the time tables you might not need help from guys like these.

Jog mapping – the productive way of working out

Perhaps inspired by french barefoot jogger and entrepreneur Loic Le Meur, and the fact that during six weeks of travelling I only got to work out twice (and swimming in the shallow pools of The Flamingo doesn’t work that well), I started jogging every day last week.

My somewhat untraditional (or rather traditional?) leather running shoes

Having to attend my two last lectures of STS in Trondheim, I was stranded in the remote town of Klæbu. With six days of reading inbetween lectures, there was plenty of time for jogging. Thus, to not feel too alone I brought my newly acquired Holux m-241 GPS logger with me for my jogging trips.

The utilitarian that I am, my biggest problem with working out has always been that it’s not immediately productive. You only produce muscles and good health, and seemingly for no tangible purpose (I know there are many, the reason why I work out anyway). There are many ways to solve this problem. You can work out by chopping wood, carry things, cycle to work, etc. In Klæbu I found another way: Jog to make maps!

This is jog mapping (or map jogging): While working out is your primary goal, your secondary goal is to improve Openstreetmap. To do this you have to jog where Openstreetmap has poor coverage or needs improving, and you need to bring a GPS logging device. Now your jogging will have a real useful, tangible  purpose, as it will help Openstreetmap improve!

At the same time you’ll really get to explore the area, and as you map it you’ll get familiar with all the paths and possible routes for your jogging. If you’re especially couragious and go jogging into peoples yards and gardens, you might also make som friends (and enemies). When you start running around houses and parking lots to log their location, you’ll eventually end up in the local newspaper too.

Luckily Openstreetmap wasn’t very well covered in Klæbu, so the Tuesday I arrived, the map looked something like this:

OpenStreetMap before jog mapping in Klæbu. (This screenshot has a different style than the following because it has been grabbed from Cloudmade.

And now, it looks like this:

OpenStreetMap after jog mapping for six days.

Oh, combining mapping with your daily life and social activities isn’t anything new, there’s always a mapping party!

Roadsharing, getting there

I have long been thinking that Facebook probably would be a good platform for car/ride sharing similar to Mitfahrerzentrale, GoLoco or the failed Norwegian Haiketorget, and since we discussed it at work today, I had a cursory look if someone have already implemented the idea, and lo and behold:

• Road2Share: 1148 monthly active users, looks like the real deal but still too few users.
• Zimride | Carpool: 6549 monthly active users, good review, has launched its own homepage, so not sure if all users are counted, could be more. Also have a partnership with zipcar at Standford.
• Peugot EcoSharing: 39 monthly active users, and seemingly unusable at the moment.

The two first look promising, but what I’d really like is for bewelcome.org to provide this and integrate with facebook, twitter, buzz and not least provide apps for iPhone and Android with location awareness. That last point is probably the killer feature here.
