L+133: Logbook

Quiet Easter Sunday here on ISS, no work at all on my schedule, although I did a little bit of work off the “task list”. Oh, I don’t think I ever told you about the task list, time to change that!

The task list is a pool of activities that have been prepared by the ground, but don’t have a high enough priority to be put on the regular schedule. If we want to do some work in our free time, or if time frees up because some activity could be completed quicker than expected, or because a planned activity was aborted, we can browse the task list and find useful things to do.

Some are bigger tasks of several hours, others are little housekeeping tasks, like replacing the batteries or the shell of a laptop, or reconfiguring stowage in preparation of an upcoming activity. Packing and unpacking a cargo vehicle is also often on the task list, in case we want to work ahead during our free time. 

And since being late with packing is really not an option, we always get a head start: the stowage specialists on the ground send up pre-pack gather lists well before a vehicle actually shows up, so we can start getting return bags ready. In the picture you can see the Node 2 endcone with all the bags we already started to pack for Dragon. Compare it with the way it looks about a month ago for our Exp 42 crew picture!

Recording video messages or educational videos for outreach purposes is also typically on the task list, as well as a couple of procedures that are permanent entries: changing the solid waste container and the urine container in our space toilet. After the first couple of times, you don’t really need a procedure for that, but an activity also has a stowage note attached, which in this case tells you which new containers to get, where to find them and where to stow the removed ones.

As you know, every item is tracked on the Space Station: by part number, barcode , serial number.. or all three of them!

Things still get lost occasionally, unfortunately. We’re all humans and as such are prone to making mistakes:  if something ends up in the wrong place (in the real world or in the inventory system), who knows when it’s going to be found! Also, things accumulate over time that should actually have been disposed of a long time ago. Not unlike most people’s homes, we can’t afford to accumulate things that are no longer necessary, because we need the space for new hardware to support the science program.

The European laboratory Columbus, after having been on orbit for about 7 years now, has seen a little bit of that. When I arrived back in November there were quite a few stowage bags on the rack fronts: so much science going on, so little space to stow the equipment! Luckily ATV5 and SpX-5 took away some bags that were no longer used and some optimization of the available volume in the endcone has cleaned up the cabin quite a bit.

In order to optimize more, on the weekends I have been doing photo-audits of our main stowage rack in Columbus, the Deck 4 rack. The stowage team at COL-CC, the COSMOs, want to have the full picture of what’s in those lockers, in order to devise a consolidation plan that will hopefully save some space! So I have been snapping away… patiently, locker by locker, bag by bag, item by item, nicely showing all the barcodes and serial numbers.

And you thought that being an astronaut was all glamour and adrenaline, didn’t you?

IT@M, the IT service company of the city of Munich, has published a statement WRT that ominous (but secretive) study that HP Consulting commisioned on behalf of Microsoft. Some juicy quotes in there. With permission from the press office of the city of Munich I have published the statement on my blog at

With the help of Google translate and my infinite wisdom:

HP study produced on behalf of Microsoft on the LiMux migration

(01/22/2013) Under the intriguing title "[Mayor of Munich] Ude has wasted millions on Linux machine?" Focus Money Online reported on a study that HP made on behalf of Microsoft. The study allegedly proves that the city didn't save in the tens of millions Euro by switching to OpenOffice and LiMux, but actually paid far more.

Karl-Heinz Schneider, head of the municipal IT service IT@M:"Of course we want to deal with this criticism. I have asked Microsoft to share the study with us. What I could gather so far from press articles however raises a considerable amount of doubt on the validity of the study and its findings." The study does not take into account the licensing costs that would be incurred for using Microsoft products. Schneider: "This simply drops seven million into the void - which is quite the biggest saving we had."

The claim that no new versions of Windows and its application would have been needed is simply not true. Schneider: "A major trigger for the decision to put our operating system architecture to the test was precisely the announcement by Microsoft to drop support for Windows NT - the operating system that was used as a standard at the city of Munich at that time. A migration to a new operating system was therefore inevitable. "

The claim that the city would have compared the cost of a current Windows 7 with a ten year old version of Linux is also simply wrong.  Schneider: "Of course we have been gradually optimizing LiMux over time. The current version is far away from the original version and can stand  a comparison with Windows 7."

The study also falsely claims that one in four city computers still run on Windows as none of the specialized procedures can be migrated to Linux. Schneider: "It is true that not all business applications can be migrated to Linux. But that is 'not all' and not 'none'. All web-based business applications can be used without any migration costs under LiMux and most of the procedures that are tightly integrated with Microsoft can be accessed with standard technologies that are also used by the Linux client.

Finally the number of remaining Windows machines in Munich that the study claims is too high. Instead of the claimed 75 percent, we have already moved 13,000 of the planned 15,000 machines to LiMux - that's almost 87 percent. "

Programmer Interrupted

The most thorough study to date that uses a variety of techniques to gauge the cost of interrupting a programmer:

subvocal utterances
tracking eclipse and visual studio typing frequencies/patterns.

High level takeaway:
A programmer takes between 10-15 minutes to start editing code after resuming work from an interruption.

When interrupted during an edit of a method, only 10% of times did a programmer resume work in less than a minute.

Definitely worth reading.
