Thoughts on bureaucracy

Written by Grigory Rechistov in Uncategorized on 05.02.2024. Tags: thoughts,

Bureaucracy has good (wut?) and bad sides.

The good intentions behind of formalizing an activity into a documented process is to reduce variation, reduce possibility for corruption and thus improve scaling. While all good things, there is a price to consider.

Automation has lower flexibility than humans have when it …

Does Suppress All Exceptions also suppress MXCSR updates?

Written by Grigory Rechistov in Uncategorized on 26.01.2024. Tags: sae, avx512, evex, mxcsr,

Incremental metrics provide most value to the development

Written by Grigory Rechistov in Uncategorized on 06.03.2023. Tags: tests, benchmarking, static analysis, incremental analysis,

Updated 2023-07-06

Hjul

Hjulparet har äntligen kommit fram. Här är vad kartongen innehöll.

Enkla snabbkopplingsaxlar och en kassettdistans insvepta i tidsenlig (från juli 2021) pappersbit. Till QR-axlarna har jag ett bättre par liggandes någonstans. Kassettdistansen kom dock till nytta vid bygget.

Snabbkopplingar

Skyddsfilm

På tal av att ramla ner i en container med stickers. Det kom tre ark med skyddsfilm:

Tre ark

Målen med klistermärkena var att:

  1. Strö lite variation till den monotona blå ramfärgen.
  2. Skapa visuellt brus som skulle dölja eventuella sprejmålningsdefekter
  3. Färgkoordinera gaffeln och ramen(, något som inte lyckades att åstadkomma den …
