It must be the guys that do the bonking

One doge hitting another doge on the head with a baseball bat, making a "bonk" sound, and saying "go to horny jail"

On the train: next stop: Horny Smokovec, then Stary Smokovec

Not unless it's a special HashWithIndifferentAccess from Rails, generally symbol keys and string keys are treated as different keys - you can even have a hash like this:

irb(main):006> hash = { 'a' => 1, :a => 2 }
=> {"a" => 1, a: 2}

TIL: you can write #Ruby hash literals in such cursed format, listing some of the keys in the 1.8 style (=>) and some in the 1.9 style (:) 🫣 (vs. listing all in one format or all in the other)

irb(main):001> hash = { 'a' => 1, b: 2 }
=> {"a" => 1, b: 2}
irb(main):002> hash.keys
=> ["a", :b]
irb(main):003> hash['a']
=> 1
irb(main):004> hash[:b]
=> 2

There are Sankey diagrams everywhere for those with the eyes to see…

For more on this, Ding Yuan et al. have a great paper and talk: Simple Testing Can Prevent Most Critical Failures: An Analysis of Production Failures in Distributed Data-Intensive Systems. The paper is basically what it says on the tin. The authors define a critical failure as something that can take down a whole cluster or cause data corruption, and then look at a couple hundred bugs in Cassandra, HBase, HDFS, MapReduce, and Redis, to find 48 critical failures. They then look at the causes of those failures and find that most bugs were due to bad error handling. 92% of those failures are actually from errors that are handled incorrectly.

Diagram showing:
initial faults (e.g. h.w. fault, bugs, misconfig.) - 92% to incorrect handling of errors explicitly signaled in s.w. - 35% of that to trivial mistakes - errors ignored 25%, abort in over-caught exceptions 8%, TODO in handler 2%; 57% to system-specific - easily detectable 23%, complex bugs 34%; the other 8% is "latent error". Everything connects in the end to "Catastrophic failures (100%).

Drilling down further, 25% of bugs are from simply ignoring an error, 8% are from catching the wrong exception, 2% are from incomplete TODOs, and another 23% are "easily detectable", which are defined as cases where “the error handling logic of a non-fatal error was so wrong that any statement coverage testing or more careful code reviews by the developers would have caught the bugs”. By the way, this is one reason I don't mind Go style error handling, despite the common complaint that the error checking code is cluttering up the main code path. If you care about building robust systems, the error checking code is the main code!

A few more weeks in a place like this would fix me… heal my mind 🩵

Re: solar in Poland: ok, beat this - a floating shack at the edge of a lake that serves fried fish, which has a pier completely covered with PV panels and is only powered this way 😄

I don't think the panthers stand a chance, a panther only has surface-to-surface melee weapons and a hurricane has air-to-air and air-to-surface ranged weapons…

iOS. I tried in Safari (iPad) later and I got this instead, and then when I clicked post again it said something like "object is in invalid state" (?), and then the tab crashed and reloaded too…

Let's search what snakes live in Poland to find which one I could have seen today… … oh no

AI graphics "snakes in Poland". There's a few small typos in Polish diacriticals (including in the title), but also one snake is duplicated, another is duplicated and mistranslated, and at least some of the snakes are like… branching out instead of being a single curved line?!

Poles *really* fucking love free stuff, so free power = awesome! There's this catch that you need to invest in it first, but there were a lot of subsidies from the govt/EU (?) in the last decade if you buy PV for your house (again, free money and you lose it if you don't buy now!)

It's crazy how much more solar there is in Poland everywhere now vs. 10 years ago… ☀️☀️ Wind turbines are rather controversial, but pretty much everyone* loves solar (*) except 1 (one) guy, whom Kaczyński intends to make the future prime minister, sadly
