Arcarum

Today the Arcarum summons got their fifth release and the associated characters (sages?) have been unlocked as well. They’ve finally raised the weekly/total point limits too, so now I’m less likely to bump into that wall when running the rounds.


Az idő pénz

Azt mondjuk, az idő pénz, aztán a következő pillanatban már azt, hogy az idő az egyetlen dolog a világon, amit nem kapsz meg pénzért. Akkor most melyik? Az első állítás, miszerint az idő pénz, nekem egy egyenlőségnek tűnik, az egyenlőség meg, mint tudjuk, kommutatív, vagyis fordítva is ugyanúgy működnie kéne.

Szerintem működik is. Ha dolgozol, az időbe telik, és pénzt kapsz érte – bár itt felvetődik, hogy mi van azzal a pénzzel, amiért nem áldoztál közvetlenül időt (például a tőzsdén vagy kamatokból). És visszafelé szintén, mert a modern élet kényelmei, amik általában nagyon sok időt felszabadítanak, nem ingyen vannak. A vonat se, a gyorskaja se, sajnos az orvos se.


Mapping

The other day I was thinking about Rich Hickey’s keynote at last year’s Conj. He goes into how the literal maps (or hashes or hashmaps or however a language prefers to call them) are really functions too. A function in maths is a mapping between sets and that’s what maps are.

Then that makes functions we normally write are just like that too, except the mappings are more abstract and defined through code. Because the mappings are so complex and indirect, we write tests to check (automated) that the mapping we defined through code is correct.

Obviously defining the exact mappings for every possible combination of the input set(s) is not feasible (that’d be a map, the end). But if “all” is not possible then how much is? What exactly is the absolute minimum amount of test( case)s that’s useful?


Gala

To keep practicing snowboard, the next target was Gala Yuzawa. It’s an apparently pretty famous snow resort, considering how it has its own shinkansen station (yes really) and probably the first destination for snow tourists seeing the huge number of foreigners (including the staff).


In motion

I don’t know how it’s at other schools, but my university had compulsory PE classes. Sure only once a week and only for two semesters, but it was still annoying. Except for one good thing: there was an option to take a few days long ski trip instead of the regular class in the winter semester. Which of course I did. It was my first time skiing and I loved it. That was in 2011.
