JohannMac··on Airbus grounds A320 aircraft amid solar radiation risk
I think that depends on the given aircraft’s configuration. Some it’s just a software change (revert to older version I think).

There are two of those units in each aircraft.

JohannMac··on Airbus A320 Fly by wire corrupted by radiation in flight
Caused uncommanded pitch down, could exceed structural integrity of aircraft. There are redundant units - unknown why this can happen given redundancy.
JohannMac··on Show HN: I rewrote my Mac Electron app in Rust
Given your destination was the Mac app, why not Swift/SwiftUI rather than Rust/Tauri? Just curious is all.
JohannMac··on My husband was laid off from Microsoft by an algorithm – after 25 years
Don’t know if this is real or not but if the person was hired in 2000 they likely received stock at $35/sh worst case. And follow on grants. It’s $450 now so I assume, at least financially, the arrangement worked well?
JohannMac··on Ultrafast Optical Detector
Novel approach to optical detection which is faster than current approaches and can be incorporated on an IC.
JohannMac··on Bridging academic research and practical Li-Ion Batteries
Great summary of need and reasearch
JohannMac··on Ask HN: C-Corp or LLC for idea stage startup?
If you are self funding, and/or funding from friendly, unsophisticated investors initially, consider first an S-Corp (that’s just an IRS election) then transition to C when you have your first professional funding and need multiple classes of stock. Easy taxes, your portion of the losses just go on your 1040. Only a single class of stock is allowed though thus the transition when you take investment from professional investor.
JohannMac··on Starlink Premium
Look in the Starlink app, under visibility after it has run for 24h and it will show you where all the obstructions are. Quite handy. Clear is blue, red is obstruction.
JohannMac··on Intel PIII: Is Big Brother Inside? (1999)
Common to have unique SN in a processor. Let the SW vendors do copy protection too. E.g. at Sonos we used them to associate with the software signed certificate such that you couldn't run a given Players software on another Player without the same SN. When making products via contract manufactures, especially in China, it was a wise procedure.
JohannMac··on Starlink User Terminal Teardown
Impressive they are putting a full steerable phased array terminal at customers home.
