Read The Thousand Autumns of Jacob de Zoet by David Mitchell, which takes place in 1799 at the Dutch East India Company trading post Dejima in Nagasaki, with Jacob de Zoet being a young Dutch trader. There are a lot of threads, from the Tokugawa closure of Japan to foreigners (called sakoku), to the hidden Christians, to the mutual xenophobia of Dutch and Japanese officials, to the emergence of a global commercial system (with de Zoet carrying Adam Smith in his travel box), to supernatural powers of zen monks, &tc., &tc… As The Guardian puts it,  “the final effect is confused. The main problem seems to be that Mitchell hasn’t decided if he’s writing a straight historical novel, a grandly themed fable or a cheerfully trashy romp.” Also read a BD taking on Animal Farm, called Animal Castle where the dictator is a massive bull and the enforcers Dobermanns. With a modern twist and both humour and resistance in the face of tyranny.

Made more rhubarb preserve, more galettes and more almond butter. Of which the later may have costed me dear since a parking car presumably damaged my most useful bike to a point of no repair, while I was purchasing those almonds. (I ended up find a used and cheap version of my light city bike to be cannibalised for parts.) I also tried to make the galettes on a traditional cast iron billig (pancake pan), but could not keep the galettes from sticking. And became a Holy Grail father by making a jar of elderberry jelly out of the berries growing from an old elder in our garden, a first attempt if the last type of berry I made use of! It proved rather time-consuming from collecting the berries on high branches to combing them from the stems, to cleaning them and to finally press them into a juice (that need be well-boiled to avoid poisonous cyanide effects!). Also made a few jars of blackberry jam out of invading vines from a deceased neighbour’s garden, which took about a tenth of the time necessary for the elderberry jelly.

Watched Old Guard 2, irremediably terrible (in The Guardian‘s terms, “this delayed Netflix sequel is an incomplete mess”). And the 2009 Japanese series Jin, another time-trap scenario when a character gets sucked into an earlier era (1860’s Edo Japan in this case) and brings changes while trying to avoid impacting the current era. As a neurosurgeon having to fight cholera with no drugs. Enjoyable enough, with a crazy samurai reminding me of Mifune Toshirō.  Apart the soapy parts and the long periods when the surgeon stares at the sun (without turning blind). But not as funny as the South Korean Mr. Queen. However it made me aware of the time when the Tokugawa shogunate ended and the Meiji Imperial Government took over. The characters include historical figures like Katsu Kaishū and Sakamoto Ryōma. I also discovered how much France and Britain were involved in this transition.

Read a (red) book I bought in Chamonix last January (sounds like last century, at the very least!) at the Éditions Guérin bookshop, The Bond, by Simon McCartney, translated in French as The Ghosts from Denali. It starts more or less like a traditional mountain climbing story, with a pair of cocky young climbers attacking a new and difficult route and managing the opening despite severe adverse circumstances, which is what Simon McCartney and Jack Roberts did for the north face of Mount Huntington in Alaska, having run out of food and facing the constant threat of collapsing seracs. It however turns into a inner introspection as McCartney gets stranded on the mythical Eiger Nordwand (just like many before him!) after his large group keeps breaking their Charlet Moser icepicks due to the cold (!) and end up being airlifted. He later manages a Winter climb of the Eiger and reunites with Roberts to attempt the south face of Denali, never climbed before. This is when the book takes off, from the sheer difficulty of the route to the amazing unpreparation of the climbers, to Simon’s cerebral embolism building up and bringing him a hair away from death, to the altruism of several other climbers on the mountain to bring him down from the death zone, especially Bo Kandiko, and to a trauma-induced complete break from climbing when McCartney got out of Anchorage hospital. This is gripping and moving and unbelievable. The book received a Banff Mountain Festival award and no wonder. The story told by McCartney is actually seamlessly completed by diary excerpts by Roberts and Kandiko, where they question their own involvement against the very real danger of dying from staying with McCartney, much more than giving up their own attempt against the deadly mountain. A terrific mountaineering book, truly. As a sad coda, Roberts died ice-climbing Bridal Veil Falls a few days before McCartney’s attempt to reunite with him.

Spent several evenings baking fig jam when returning from the Alps as the fig tree was full! And ended up with a total of 35 jars. Resulting into a full “marmalade closet”, as in the past weeks my mom home-made the same amount of peach jelly and my wife’s mom even more rhubarb marmalade jars. Enough to stand a whole year of lockdown, jam-wise. And ate some of the few but tasty peppers that grew in our garden, for the very first time, despite the welcomed tomato and squash invasion! Also ate a terribly greasy risotto in a supposedly highly noted restaurant…

Started watching Dark on Netflix, a German dark time-travel fiction. But while I enjoyed the complex story, the play of the young actors, and the appeal of watching a show (and a Greek play within the show, with Ariádnê and Thêseús of course!) in German, the endless paradoxes of time-travel and the duration of the series made me stop after a few episodes, the town of Winden keeping most of its mystery for me.

One challenge on code golf is to find the shortest possible code to identify whether or not an integer belongs to the binary cyclops numbers which binary expansion is 0, 101, 11011, 1110111, 111101111, &tc. The n-th such number being

a(n) = 2^{2n + 1} - 2^n - 1 = 2\,4^n - 2^n - 1 = (2^n - 1)(2\,2^n + 1)

this leads to the above solution in R (26 bits). The same length as the C solution [which I do not get]

f(n){n=~n==(n^=-~n)*~n/2;}

And with shorter versions in many esoteric languages I had never heard of, like the 8 bits Brachylog code

ḃD↔Dḍ×ᵐ≠

or the 7 bits Jelly

As a side remark, since this was not the purpose of the game, the R code is most inefficient in creating a set of size (x+1), with most terms being Inf.
