balance sheet snowboarding season 2017/16

For a change a winter with snow again, allowing a early start of the season (December 2). Due to early easter (lifts closing) last run was on April 14. The amount of snow would have allowed boarding for at least another two weeks. (Today, on May 10 mountainbiking is still curtailed, routes above 1650 meters of altitude are not yet rideable.)

OTOH weather sucked, extended periods of stable sunny weather were rare and totally absent in February and the first half of March. - I only had 3 days on piste in February. I made many kilometres luging during that time. ;-)

Anyway here it is:

Fixing the boot-delay

Some time ago my computer stopped booting fast, it was stuck for about 10 seconds at Wait for Network to be Configured. Which seemed strange, since I am using systemd-networkd with a simple static configuration.

[Match]
Name=enp2s*

[Network]
Address=10.0.0.140/8
Gateway=10.0.0.138

Debugging showed the expected quick network setup followed by "NDISC":

Given that I am not running a local IPv6 network I have simply added IPv6AcceptRA=no to the [Network]-stanza and bootup is fast again.

balance sheet snowboarding season 2016/17

Another year of minimal snow. Again there was early snowfall in the mountains at the start of November, but the snow was gone soon again. There was no snow up to 2000 meters of altitude until about January 3. Christmas week was spent hiking up and taking the lift down.

I had my first day on board on January 6 on artificial snow, and the first one on natural snow on January 19. Down where I live (800m), snow was tight the whole winter, never topping 1m. Measuring station Diedamskopf at 1800m above sea-level topped at slightly above 200cm, on April 19. Last boarding day was yesterday (April 22) in Warth with hero-conditions.

I had a preopening on the glacier in Pitztal at start of November with Pure Boarding. However due to the long waiting-period between pre-opening and start of season it did not pay off. By the time I rode regularily I had forgotten almost everything I learned at Carving-School.

Nevertheless I strong season due to long periods on stable, sunny weather with 30 days on piste (counting the day I went up and barely managed a single blind run in superdense fog).

Anyway, here is the balance-sheet:

2005/06 2006/07 2007/08 2008/09 2009/10 2010/11 2011/12 2012/13 2013/14 2014/15 2015/16 2016/17

I am wondering …

I am wondering how many years it is going to take me to stop expecting snow below 2000m in December. This has now been the third year in a row with basically zero snow until christmas up to the top of the mountains around here. (And this year it is not going to change anymore, there might be a tiny bit of snow on January 3, but not enough to ride a board on.) I should have grown accustomed to it, but I have not managed yet, it still feels like a let-down.

some illustrations.

balance sheet snowboarding season 2015/16

A very weak season, mainly due to two reasons:

  • weather: It was just too warm. Pre-season in November things looked hopeful with early snow, but December 2015 was absurdely warm. According to the weather station Damüls Hertehof (1580m above sea level) there were only three days in December when temperatures fell below 0° Celsius. I had my first snow day on December 6 followed by 3 more days in December (12, 19 and 20) with continuously worsening conditions. I gave it another chance on January 6th, but things had not improved and I paused until January 21, which was the first good day.
  • On February 7th 2016 I had a small accident at luging, resulting in a (partially) torn ligament at my left ankle joint. Joy. No snowboarding until March 13. My season ended on April 10, when Warth/Schröcken closed.

Here is the balance sheet:

How to put on one's hardboots, when ligaments are damaged

I have finally managed to do (a little bit of) snowboarding again this weekend. Previously I had failed early, when trying to pull on my hard-boots. I had (partially) torn some ligament in the ankle joint in February and am generally fine now, but exactly this movement still caused pain.

What worked was to

  1. take the liner out of the boot,
  2. pull on the liner,
  3. step into the outer shell.

Dual boot Debian (stretch) and Windows 10 (UEFI)

I have just assembled and upgraded to a new computer (ct 11 Watt PC with Skylake i5-6500) and chose to go from BIOS/MBR to UEFI/GPT. The computer needs to also run Windows (in this case 10) and so I had googled in vain before for a matching dual-boot howto.

It turned out to be unnecessary, it is straightforward.

  1. Install Windows and leave some space for Linux. (I used rufus to build a UEFI USB install image).
  2. Install Debian. Stretch-Alpha4 di just worked and adds a entry for Windows to the grub menu
  3. Reboot and enter UEFI setup, and select the Debian installation as boot option.

balance sheet snowboarding season 2014/15

A very late start into the season, with a nice ending.

We had about zero snow until after christmas, and not just down in the valley, but also at 2000m in the mountains. My first run was therefore very late, on January 1st, followed by two short excursions (8:45 - 11:20) due to too many people on January 5th and 6th.

After that we had more than enough snow which allowed me to go to Diedamskopf most of the time (basically only natural snow there, which makes better slopes). I went there almost exclusively until they closed on Easter sunday after heavy snowfall in Holy week, and had 5 more days therafter In Damül;s and Warth/Schröcken. Last run was on April 19.

Here is the balance sheet:

2005/06 2006/07 2007/08 2008/09 2009/10 2010/11 2011/12 2012/13 2013/14 2014/15

What does not show up here is the number of times I walked (with and without snowshoes) up the mountain and used the lift down and obviously also tobogganing.
