Contesting with N1MM on Linux

N1MM+ has been the go-to contest logger for many hams and, thanks to its networking features, also clubs. Sadly, it's only for Windows, it's closed-source and the bugs (whether in N1MM or Wine) don't make it any more fun.

Setting up Wine

1. Install any decently recent flavour of Wine. Usually the one provided by your distro's package manager is fine.
2. Install winetricks.
3. Set the required environment variables. To work inside this wineprefix (which is, in short, a self-contained "fake" "Windows" "installation"), you need to specify its path inside every newly opened terminal window.

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
