Treason doth never prosper, what’s the reason? For if it prosper, none dare call it Treason.

My $0.02: - The stick-and-rudder skills aren’t hard and not the main reason people die. It’s the decision making that kills. - The “faster to fly” than drive for me starts at about 3 hrs drive (wind, preflight time, takeoff / climb &#x

With 10+% annual inflation in US in the last 2-3 years, 20+ P/E doesn’t look bad at all. Actually anything under 40 or so should be a strong buy.

Thanks for explanation. I will read the code to see how sharing works.

That’s not what I saw in the code but I didn’t spend much time so I might be wrong. I’ll check it more carefully later. But if this indeed is whole DB then it’s very limited use case.

Does the server reads specific rows from spam numbers DB or the whole database?

Evil server stores BOTH encrypted and plain text phone number in the same db row

Exactly, plain text phone number in the same db row

by lsh123 2y ago
If we assume that server is “evil” then the server can store both PIR encrypted and plain text phone number in the same row in the database and when this row is read, simply log plain text phone number. What do I miss here? We can send PIR

Since for telescope what matters is the surface size of the mirror (light collected is proportional to surface which is proportional to r^2), the 9m telescope is ~1.9x better than 6.5m one. This is a big difference. Not even counting the lo

Not sure what exactly are you looking for. Bunch of info is on FAA website, for example: https://www.faa.gov/air_traffic/publications/atpubs/aim_html... https://www.faa.gov/air_traffic/fl

DME (distance measuring equipment) is much simpler than LORAN. However, navigation computers can use multiple VOR / DME signals to compute position similar to LORAN or GPS. The problem is that DME / VOR are typically limited to 50

Botched go around killed many pilots. May be trimmed too much up for landing with flaps and didn’t push nose down hard enough. In general, touch and goes in a high performance planes is not a good idea (no time for checklists, runway length

I also got my license around that time with eb6, paper charts, VORs, NDB approaches, … and I don’t miss it a bit. Nostalgia - yes. But not missing it. I like to fly direct, I like to get LPV approach to 200 feet at an airport that would nev

Same is true for aviation nav aids: VOR, ILS, … stations transmit their name in Morse code for identification.

I fly ifr nearly all the time with exception of local flights like a test flight after picking up the plane from annual (even then I am talking to tower or approach just in case). The main reason for me is that I like having someone (atc) w

The purpose of initial training is to teach the pilot how to fly a plane “by feel”. The best PC simulators still lack the details: How does wind sound change with airspeed and AOA? How does wing tell you it’s about to stall? How does the en

1/ Visual vs instrument approach. The main difference in this case is separation requirements that ATC must provide. Specifically, under IFR rules ATC mus provide 3 miles / 500 feet altitude separation minimum. For visual approach

Don’t use ORM for performance critical DB operations and write SQL by hand might be another answer. Case in point: I recently improved performance of my email app by about 250x by replacing SwiftData with native SQLite database (and manual

+1 to the above. ATC is working to get * ALL* traffic going and if one pilot doesn’t want to do what everyone else is doing then this pilot goes to the end of the line. Company procedures or not, SFO parallel arrivals require visual separa

I can’t speak for everyone, but the company I work for takes this very seriously and does its best to comply with the law. Said that, all of it is very complicated. Most (if not all) privacy problems I observed so far are caused not by mali
