I managed to get out for my yoga classes Saturday and Sunday mornings. Saturday afternoon I spent a lot of time faffing and failing to go to the public skates I'd tentatively pencilled in; eventually I dragged myself out for the last one and unsurprisingly I felt much better for having done so. It was much easier to drag myself there on Sunday, and I had a bonus surprise meeting with a work colleague, and a lovely long chat while we skated.

Then it turned out Charles's usual lift to hockey practice (alternate Sunday evenings) had fallen through, so I said I'd take him. I had the bright idea of asking the coach if there was room for me to hop on too as a one-off addition to the class, and so I got a bonus 2-hour ice hockey practice. Oh, that felt so good.

Yesterday I switched things up and took Nico swimming in the early afternoon, which I found surprisingly tiring, and went to yoga in the evening. I got chatting to a fellow student afterward, and it turns out she also works for the university on the same site as me, and knows some of my colleagues, because Cambridge is Like That. We swapped some class recommendations and may stay in touch.

I'm really glad I picked up the hot yoga pass, it's been fun to do regularly and if nothing else it's ensured I left the house pretty much every day. If money were no object I might consider a more regular membership, but it's pretty expensive when not on a promotional pass. Plus between my hockey commitments and the additional gym sessions I want to add in January, I'm really not sure I have the time. Maybe I'll think about it again after the university season is over.

Tomorrow I'll see out the old year with one last yoga class, and then go to the last public skate of the year at the rink in the early afternoon. I'm vaguely planning a movie night with Tony and the offspring, watch the fireworks broadcast from London, and then probably zonk.

Aside from exercise I've mostly been reading, with a side of listening to hockey podcasts fall in love with Heated Rivalry.

Drag instructions onto the flowchart and press space or click the map to start executing. On later levels click the map while executing to increase the speed.

Since my last post I added some more programmer-y levels up to level 15, cleaned up some of the earlier levels, and improved a bunch of UI things like saving which levels you've unlocked. Most easily played on web, on either desktop or mobile, but you can clone the source and build for windows or linux too. (https://github.com/CartesianDaemon/rusttilegame I should compile a windows binary to download too if that would be useful for anyone.)

If you do play, it would be really helpful to hear how far you got. And if you have time, which levels were easy, which were hard, what was nice or difficult about the UI, etc.

Shoresy (seasons 1-4)

Shoresy is a Canadian comedy show about an ice hockey team, currently available to stream on ITVX. It is very crude (swearing, sex & toilet humour) and very funny, and it loves hockey. The episodes are short, around 20 minutes, and the seasons only have six of them, so it's relatively fast watching.

(ITVX insists on checking in with me at the start of each episode that I really want to watch "very strong language and adult humour". This made it great for watching in bed because if I fell asleep, it wouldn't keep playing past the end of the current episode.)

Anyway, despite the aforementioned crudity, it is often weirdly wholesome. There's a lot of little repeated catchphrases, I think maybe the show's own meta-commentary on how much of hockey discussion is cliché-ridden, but like Terry Pratchett wrote, sometimes things become clichés because they are true. Hockey brings people together. Hockey players give back. By the community, for the community. Go till you can't go no more. Episode 3.6 in particular manages to capture how a high-stakes hockey game feels, and is probably my favourite of the entire four seasons.

So anyway, this weird crude funny show got past my usual reluctance to watch TV on my own, and even to rewatch some of my favourite parts. I gather season 5 started showing in Canada on 25 December, but no idea if it too will come to ITVX.

(Trivia point: the executive producer of Heated Rivalry is Jacob Tierney, who also produced Shoresy. I didn't realise this until I'd started watching, but ok, this guy loves ice hockey, just like Rachel Reid does, no wonder he chose to adapt her books.)

Christmas Day and Boxing Day

We had our usual quiet Christmas Day: stockings, family zoom, salmon-elevenses, roast bird dinner with my brother Jonny, a silly film (Shaun the Sheep: Farmageddon). I even managed to drag the children out to the park for an hour or so before dinner, including some table tennis and frisbee.

One of my personal Christmas traditions is watching the Nutcracker, usually in a cinema broadcast, and I just couldn't make that work this winter. So I was really charmed to find a broadcast of the Royal Ballet's production on iPlayer; the advantage of watching it at home is that I can have a quiet chat with my brother alongside without bothering anyone else.

This morning I woke up nice and early and headed out for another of my booked hot yoga sessions, followed by dropping in on my old friend Shaun for a long-overdue catchup. This afternoon has mostly been reading and TV, and the evening will probably continue the same way.

doubly dual shuffles

Here's a pearlescent xmas gift for you!

There are four variants of the algorithm for shuffling an array, arising from two independent choices:

  • whether to swap elements in the higher or lower parts of the array
  • whether the boundary between the parts moves upwards or downwards

The variants are perfectly symmetrical, but they work in two fundamentally different ways: sampling or permutation.

The most common variant is Richard Durstenfeld's shuffle algorithm, which moves the boundary downwards and swaps elements in the lower part of the array. Knuth describes it in TAOCP vol. 2 sect. 3.4.2; TAOCP doesn't discuss the other variants.

(Obeying Stigler's law, it is often called a "Fisher-Yates" shuffle, but their pre-computer algorithm is arguably different from the modern algorithm.)

Merry Christmas

Yesterday (Christmas Eve) I worked a half day from home before finishing for the year. I spoke to a few of my family on the phone. I went skating with some of my uni teammates on the last public skate until Saturday, but sadly failed to persuade any of the others to wear a santa hat along with me. I brought a teammate's kit back to my house so I know I have it to take to meet her in Prague next month (did I mention I'm going to hockey camp near Prague in January with the Women's Blues? same coaches & place as I went to last June). I got stocking supplies for the household.

In the early evening Tony, Charles and I gathered for the ritual watching of Die Hard and followed it with Knives Out. I enjoyed both films very much, still. I filled the stockings for everyone before going to bed, and fell asleep over a library book.

I am grateful for my home, my family, my friendships, and all the good things in my life.

Aye up.

My visits to write LJ entries seem these days to be occasional, in every sense. But it's Christmas, and I know a couple of you look for me at Christmas, so here we are.

To cover the important traditional points: I'm at my parents' house, we've got the fire in, I've snuggled up the pigs in blankets, Dad and I have pints of beer. More to the point, it is proper brown beer that tastes brown, which is vanishingly hard to find these days. Rockin' Rudolph made by - of all people - Greene King. Who'd have thought it?

Today, we had a delightfully throwback experience: lift tree in from garden*, adorn tree with fairy lights, plug in fairy lights...

Nowt.

Not a sausage. )

Also, as usual: I've written some Christmas puzzles. If you'd like them, drop me a line.

Reading, Listening, Watching

purplecat: The Tardis against a sunset (or possibly sunrise) (Doctor Who)
[personal profile] purplecat
Reading: Adventures Across Space and Time: A Doctor Who Reader - I love the idea of this book - a collection of academic writing about Doctor Who that can stand as a starting point for scholars, but I knew when I bought it that I would find it quite hard going because I'm not a humanities scholar and I find their idiom somewhat hard-going.

Listening: The Radio Free Skaro and, this year, the Starship Alexandria Advent calendars. I am, as I always am, somewhat behind. But at least this year I'm up to day 18...

Watching: We watched The War Between the Land and the Sea and it was... fine? I don't quite feel it justified its existence. The ending was unsatisfactory - our heroes got to be in love, but everything else looks like a complete garbarge fire. It was very good in places, fine in others, kind of dull sometimes and events often felt like they were happening in order to get to the next plot beat rather than because they made internal sense. If it hadn't been Doctor Who adjacent, we wouldn't have watched.

Turns out one of my uni hockey friends has a long-standing history channel on YouTube, and of course he made a video about ice hockey history. I think I'd have liked it even if I didn't know the creator, enjoy:

In shock news, hot yoga is hot

The hot yoga place has two levels of classes: "hotpod flow" and "nurturing flow". In January I found the nurturing one a bit too relaxing and slow, and I've been doing the free yoga classes through work pretty consistently all year, so I thought sure, I'll be fine in the standard class. I'll have to modify some of the harder positions but I'm used to that.

It was hot in the class. Not sauna hot, but I was definitely finding it harder than I'd expected based on the January classes. I took the teacher at her word about it being fine to take breaks and drink water as needed, but well before the end I just had to stop, sit, and let my heart rate come down. She checked in with me, and I assured her that I know my body and I'm not going to let myself faint, but yes it was harder than I'd expected. I've switched my classes for the next couple of days to the "nurturing flow", so we'll see how that goes.

slightly gross body stuff
My workout clothes were saturated when I finished. I thought I was sweaty after Huskies practice (two hours skating hard, trying to keep up with young men), but this was a new level. Luckily I had a hoodie and skirt to throw over the top for the bike ride home - it's a weirdly mild December week but not so mild I wanted evaporative cooling all the way. Absolutely everything went in the wash when I got home.

I emptied my 950ml water bottle in/just after the practice, and had another couple of litres of water over the course of the evening, this time with my trusty electrolyte tablets, and managed to see off the lurking dehydration headache. I'm going to make sure there's electrolytes in the in-class bottle too from tonight onward.

Sunset at 15:49

On this shortest day of the year, Nico and I went to Clip-n-Climb first thing, cycling there and back together through a heavily overcast but weirdly mild December day. We did a little Co-op run on the way home, and then I unpacked the hire car before returning it. I decided against buses or scooters and walked the hour or so back home, including a little diversion to collect a yoga towel from Decathlon. If all goes to plan, I will cycle to hot yoga this evening in the dark (and quite probably the rain) for the first of my "festive pass" sessions.

(I mean it about being weirdly mild: both cycling and walking I had to take my hoodie off because I was too hot.)

Technically I started the 21st of December still awake at midnight, and watching the first couple of episodes of Shoresy, a Canadian comedy TV show about ice hockey, on a friend's recommendation. (Same director/executive producer as Heated Rivalry although I didn't realise that until after I'd started watching.) Very crude, very funny.

Ice hockey, climbing, walking outdoors, yoga. Spending time with my offspring, thinking of my friends, and taking care of myself. If this is a turning day of the year, it's a good set of things to mark it.

Strictly we are not yet into the "mellandagarna", the in-between days of Christmas-to-New-Year. I'm still working until lunchtime on Wednesday, but a lot of the usual rhythms of my life and my household are paused now. School's out, hockey practice is out, everything has "holiday opening hours" listed and I'm feeling a bit unmoored. (Being ill most of the last fortnight probably hasn't helped.) My yoga pass is part of my attempt to put a little structure on the downtime.

Weekend fun, and the week to come

Yesterday after work I did a library run (more Rick Riordan!) on the way to pick up a hire car for the weekend. Then drove with Charles over to Northstowe for the Kodiaks Christmas party at the Northstowe Tap and Social. Secret Santa, noodles buffet, attempting to introduce an American to prawn crackers - she didn't like them - and a drag queen bingo.

I left the party a little early to go to the last Warbirds practice of the year and was so glad to be back on the ice again. (Yes, in shock news, 48 hours after having a massive mood crash about having a cold forever, I was well enough to skate hard for 90 minutes. It is a weird signal, but a consistent one.) It was ten days since my last practice, and it's now ten days until my next one (Kodiaks 2 on 30 Dec). I missed it so much. Practice was just the right level of challenging that I'm really pushing myself but not feeling like a hopeless incompetent, it was just what I needed, as was seeing my teammates again.

(Charles made his own way home from Northstowe by bus)

Tonight is the last Kodiaks 1 game of the year, for which I will be herding the volunteers as usual, and rocking my lovely new manager's coat (incredibly warm knee-length hooded puffer coat, personalised with the club logo and my initials). There is apparently a post-game clubbing plan. And tomorrow morning I'm taking Nico climbing. Somewhere in there I'm sleeping, honest.

I have 2.5 more days to work this year, and I am so ready to be done. The giant Ocado order is booked for Tuesday evening. I have a very large pile of borrowed books to read, and the rink public skate schedule in my calendar. The hot yoga place had a special offer, so I also have a 12-day pass to get me through the lack of hockey practices. They are quite strict about turning up sick, and I still have a bit of a cough this morning, so I won't be using it today. But hopefully tomorrow.

I am the stage of being ill with a cold where it feels like I will never be well again, I barely even remember what it is to not cough, and all is doom. Woe, woe is me. [From experience, this stage is usually about two days before I actually get fully well, but try telling my feelings that.]

(brought to you by having to miss yet another hockey practice tonight, the penultimate one of the year, and being sad about it)

Cheering myself up with the news that Heated Rivalry comes to the UK on 10 January. I am going to be very normal about it. Meanwhile I await a delivery of Rick Riordan books from my dealer the buddy who got me into them, and Instagram is doing its usual creepily-accurate targeting, supplying me with Yorkshire Percy Jackson and advertising a PJ musical in Peterborough next spring.
