I joined Twitter for the curated news feed. You can still set your feed to timeline so you don’t get anything the algo feeds you. I’m staying; my feed is a great source of news and opinions from various prominent scientific, tech and hackin

The more I learn, the more I find that “best practice” isn’t always best. It should be called good defaults. For example “Disable ssh password auth and use keys”. It depends on your threat model. A good password can be secure and may in som

The way GPS was designed to work originally is two sets of codes. Course Acquisition (CA) code which repeats at 300ms intervals with a deliberate bias was designed to bootstrap the receiver into locating its position in a 1-week Precise (P)

This is a basic story of how some guy pumped a shitcoin in third party markets to make his 1e100 coins appear to be worth a lot, but lacked any exit liquidity to actually make any money. I wonder if the tax office would allow people to valu

I set up an auto-correct for 'ducking' to replace it back to what you actually want to say. Also whilst Apple is reading this, please stop changing "were" to "we're" out of context. Ugh.

If a phone can take down airline communications, there is something wrong with the aircraft. These should be properly shielded lines. There are now millions of hours of airline ops with phones on. It doesn’t cause any problems. Also hot tip

The summary should be to use a request which satisfies the long term minimum cpu required at any given time. Then if you’re happy to allow it to burst then don’t set a limit. If you want consistency and constant runtime, set a limit. If yo

Oh and make sure you raid the stationary cupboard. 8 years later and I still have a surplus supply of 4-pens!! Don’t take more than an item a day though. Stock up on printer paper and things like that.

The wallet address was a bunch of leading zero's, indicating it was probably generated from a vanity address - likely Profanity. Which was recently discovered to have a fault in the private key generation resulting in a 2^32 key space.

I remember reading an article once where they said SIP sends the hash of the application in the clear. This allows your ISP to track known application hashes you have installed. Unsure if this is still accurate.

Yeah but to be fair, aviation statistics would also be 10% as bad if they excluded people who didn’t fly into bad weather, took off overweight, didn’t have enough fuel in the tanks, ran out of light or were too fatigued, or couldn’t say ‘no

It’s all about weight. These aircraft are optimising to the last kilogram. If you add 10kg more, that may be 1 less pax, or 15 minutes (34 NM) range.

I know of 7 engine failures with people I know and they all walked away safely after landing in a field. It’s rare it ends up in a fatality, even without a parachute. Most are in fact twin engines that suffer an engine failure and mishandli

What you’re after is a piper cub. Incredible short field takeoff and landing performance. You can land from an engine failure in a tiny amount of space, quite safely. The comments so far seem to presume the parachute is the only thing requi

I learned that in SwiftUI if you don’t want a view to re-render when one of its properties changes, but you need it to have that property/state because it needs passing to children, you can just make it a regular variable without the @

The problem with Cirrus is the parachute. Insurance companies don’t like it because instead of half or more of aircraft landing safely on a road or in a field, they are now all write offs. This then adds insurance premiums. We are also now

Also the challenge of old receivers was which Doppler shift frequency to listen on depending on if the target satellite is going towards or away. By knowing the rough location (from cell towers, known wifi AP’s etc), they can get an instant

First rule of optimisation - don't. Second rule of optimisation (experts only) - don't, yet. However in this case this is the hot path half the internet uses (granted, M1 specific in this case), and a 6% speedup is significant.

Or they are so advanced that their “bodies” are made up of individual units teeming with nanotechnology components, most of which are atoms wide, working to generate power from atoms absorbed from external environment, self repair and more.

I’ll save everybody their time: it’s just a bunch of Amazon links to strong regular umbrellas you can use to hit people. I was hoping for something out of Kingsmen, like kevlar, retractable blade and single shot blow dart!
