So, even GNOME Classic/Fallback has been shellified in recent GNOME3 releases. Used to be Classic was still using metacity and a stripped down GNOME2 panel, but now it's a "skin" of gnome-shell. With all the performance annoyances that brings when you mix a 3D compositing window-manager partly implemented in javascript, with any video and reverse engineered NVidia drivers. Sigh.

I think it's time to move to a simpler window manager for my workstation. Back to Window Maker it is! I even still had my original configs lying around - timestamp on the dir was '99! :)

Apparently the next village along is Lulsgate, which is pretty funny (especially if you speak colloquial dutch ;) ).

A KLM 737 at Schiphol in a very retro (50s? 60s?) livery. Anyone know why?

Ah, that's what it was. Thank you Internets. :)

When you're in a dracut initramfs emergency shell with no job control cause of an fsck issue, and that one inode with a flag it shouldn't have turns into a seemingly endless list of them.

I eventually gave up and hit reset. Even the fsck -y the next time still took tens of minutes to run.

In case anyone is interested in using GNU Octave / MatLab to do distance calculations in adjacency matrices for graphs. Very interested how to speed these up, if anyone knows. #octave   #graphs   #shortestpath

Networking WTF of the day:
 
So this is interesting (to TCP geeks).

+John Looney noticed that:

    while true; do telnet localhost 50000; done

will eventually succeed in connecting (nothing's listening on port 50000), and, strangely, it connects to itself. What's happening is that the ephemeral port allocated for the socket source is actually accepting the connection, resulting in a self connect.

Even more interestingly; if you have two machines, and arrange matters so that each connects to the other using the other's source address as their target address, the connection is established. This can be shown using socat as follows:

    On machine A: socat stdio TCP:B:50000,sourceport=50001
    On machine B: socat stdio TCP:A:50001,sourceport=50000

+Kevin Lyda and +Paul Jakma did some further investigation, and it looks like this is how the "simultaneous connection synchronisation" of TCP works - see figure 8 of RFC793. General opinion of the systems administration people I've shown this to is "WITCHCRAFT!"

Your Interesting Network Thing Of The Day.

For your next task: figure out how to make this into a connection-interception hack. Easiest to achieve on localhost due to the size of the address:port space, but still...

(NB: in the 'two machine' scenario, you have a very short window to establish the connection. Wrapping each socat in a while true loop made it succeed after about 40 tries.)

Not sure how you end up with NaN here...

It's a filtering function.   The degree of filtering determines the number of pages that need to be displayed.   So that number isn't constant.   The real question is why they compute the current page as a function of that as well, when it really ought to be straightforward, but there is likely some subtlety we are missing.   I suspect it's not just "because they are dopes."

Frame cracked at the bottom bracket. Looks like it started in the weld with seatpost. Hopefully Ridgeback'll fix it under warranty, cause 3 odd years is a bit quick for a frame to fail..

Aluminium Vs carbonated water in the process of freezing: no contest!

The dent is where the water actually forced open a /tiny/ little crack, and spewed out of it, rather than pushing out the metal.

Classic, uncomplicated, stylish French food, and good value to boot. Great find of a restaurant, which I'll be going back to if I'm in Nice again.

Very imaginative menu. The food was very nicely presented, and tasted as good as it looked. We really enjoyed our meal!

Rented a Giant TCR road bike, while on holiday in Tuscany. When ordering they asked me for my measurements. So when I collected the bike it was already setup almost perfectly for me. The bike was in perfect condition, and I was supplied with a saddle bag with multi-tool and inner tubes. I had a great few days cycling in Tuscany! One thing to be aware of is that Google Maps, as of this writing, shows the wrong location! Google shows them being in Navacchio, when actually they're ~1km further down the road toward San Benedetto / Cascina - across from the petrol station!

We had delicious seafood chowder, crab linguini and seafood pasta. Very pleased with our meal. Must have a good reputation locally, because they were full the whole time, and continually having to turn people away!

Customer experience & service 2nd to none. The staff are a nice, friendly bunch. They all seem to live and breathe bikes - literally their idea of a nice holiday is to go cycle up a mountain on a Spanish island, or all across Europe. No matter what you're looking to buy or needing to get fixed, from small stuff to a whole bike, they're always happy to discuss your needs and give you the benefit of their experience & knowledge. If that wasn't enough, they really shine on after-sales service and going the extra-mile to make sure you get the best out of your bike. I bought a commuting bike from them earlier this year, and they offered a years free labour on servicing on it - which was great! About to buy a 2nd bike, a nice road bike, from them in fact!
