jadams5··on Emergency SOS via satellite
As a counterpoint, my cardiologist suggested I get an Apple watch so I could keep a better eye on things and send him any questionable ECGs. At least some doctors seem to think there are positives.
jadams5··on Study finds link between 'forever chemicals' in cookware and liver cancer
For folks having issues with food sticking to cast iron or carbon steel, try learning to cook on stainless. It's much more prone to sticking, but if you can get the technique down well enough to not have eggs stick on stainless then switch to cast it's a walk in the park.
jadams5··on Chemistry of Cast Iron Seasoning: A Science-Based How-To (2010)
Gotta be careful with the wire wheel, it's possible to get the surface too smooth and the seasoning won't stick as well. Source: I've stripped and re-seasoned 20+ pans and the one I wire wheeled has never been quite right. People on /r/castiron also advise against it. Even for pans where the sand cast finish was milled smooth from the factory.

jadams5··on Back Orifice (1998)
Oh wow, yep, that's exactly what we figured out. Their save file format stored the password hash, but didn't actually encrypt or obfuscate the grade data beyond just whatever serialization they were doing. We were starting on figuring that format out when we noticed that creating a new save file with or without a password changed a byte right before the password off and on... flip it off and the app no longer prompted for the password... edit/save in the app, flip it back on, and that was that. edit: I should add, rather than get expelled we got a ton of extra credit for it since it was at least sort of sanctioned.
jadams5··on Back Orifice (1998)
Oh man, yeah also adding to the list of people that abused their highschool computer labs with this. We had so much fun, but we eventually drew the ire of the school IT admin. After class one day the teacher took us aside with the admin and asked if we had installed BO on the computers, which we of course denied... they "believed" us, heh, but gave us a stern warning that whoever was doing it should stop. We would have all probably ended up with felony charges these days.

The next year, so 1999, we actually got approval to attempt to change our grades as an exercise. We actually managed to do it by sneakily copying a floppy one of the teachers used to store their grades with a program called Integrade. We took it home, reverse engineered the password protection to disable it, changed our grades on the copy, re-enable the password protection with the original password, and turned that in as our proof. Our teacher was impressed and super sketched out/nervous at the same time. I guess they never considered we'd succeed and get access to the whole class's grades...

jadams5··on What I know about cleaning and seasoning cast-iron skillets
Yeah, I've cooked eggs in cast iron for several years and I think a lot of the advice I see is wrong. You really have to get the pan fairly hot IMO, if they don't bubble as soon as you pour them in then I get a lot more sticking. But like you said, definitely not sear!

On my electric stove I let the pan warm up on medium heat for 5 minutes or so until the edges of the pan are good and hot, then add butter, let it almost brown for 30 seconds or so (if it burns the butter, too hot), then toss in the scrambled eggs which should immediately bubble and start cooking. Some quick stirring and you're done cooking in about 1-2 minutes for 2-6 eggs.

jadams5··on Beeple Mania
NBA Top Shot is major sports' entry into NFTs and is already dominating by market cap while it's still in beta. I've only been following it for a few weeks, but collectors are going nuts, but not quite to the point of some other NFTs yet. It still seems to be a fairly small crowd doing most of the buying and selling compared to the NBA's broad reach.
jadams5··on “WSB veterans know that they're making a suicide charge for the memes”
That was posted 4 days ago, long before the ladder attacks and disinformation campaigns desperately trying to shift attention away from GME. People need to understand the risks involved and not sink their life savings, but there is definitely more going on here than what you'd see in a crypto pump and dump. When a hedge fund shorts 120% of available stock, then retail investors don't sell, and aren't swayed by every trick in the book... something is going to give.
jadams5··on Too Many Video Streaming Choices May Drive Users Back To Piracy
10'ish years ago I remember people being mad at the cable companies for bundling all the channels together into all-or-nothing options. Why did I have to pay for ESPN when I just want the SciFi channel? Here we are today with lots of options where you only pay for what you want and now people want them all bundled back together again!
jadams5··on Ask HN: Looking back, what have you wasted lots of time on?
Interested to hear about what your issues with Ansible were. It's been a game changer for us over the past couple years. Manual processes that used to take an engineer a week to do manually are done in 20 minutes and correctly every time.
jadams5··on Maybe Warren Buffett Is Warning Us About Something
A friend of mine that's self made and worth about $40m strongly advised me to cash out my 401k. His reasoning just boiled down to who has your best interest at heart, you or some random broker in New York? If you think you can do a better job of putting your money to work, then you should. To be clear, he wasn't talking about buying mutual funds.

My counterpoint is that my wife would kill me if I cashed out my 401k.

jadams5··on How do black holes destroy information and why is that a problem?
(also not a physicist) I think you're correct that objects falling into a black hole never cross the event horizon from our reference frame, but at the same time the light from the object red shifts towards zero energy as it approaches the event horizon as well.
jadams5··on Maker Faire halts operations and lays off all staff
I founded and am still heavily involved in a makerspace that's doing pretty well (8k sqft facility, 4 staff). Focusing on equipment doesn't work, you have to focus on community building. The only equipment that will draw people are the high ticket $20k+ tools, but you have to have the community first to be able to get those grants.

Seek out grants to start a scholarship fund to pay for people that can't afford memberships.

jadams5··on Is Conference Room Air Making Us Dumber?
I got this model several months back and have been really happy with it: https://smile.amazon.com/gp/product/B01FYWU2IS/

I got it to monitor CO2 levels in a house without central air. It's pretty amazing how quickly it rises without the air on or a window open. If the air in a room feels "stuffy", it's probably over 1000 ppm.

edit: It's just like what you'd find in any modern commercial building in the US, just with a much older form factor of toilet. When we moved in I got curious why most new homes don't have them. Found out that they don't use any more water than a normal toilet, but they do require a higher water flow rate. The high flow rate requires at least a 2" water main into the house (which we have), while most modern residential construction uses a 1" or less.

Yep, it's a two pipe system. One of the first things I did was verify that the traps were all functioning. Amazingly enough, they were!

The house was built in the 20's by a commercial plumber who put in some more commercial-style amenities including some state of the art for the era tankless flush-valve toilets. I love them, wife hates them.

jadams5··on The Lost Art of Steam Heating (2017) [video]
I live in a 90 year old house that still uses the original steam heated radiators. It's actually been a lot of fun learning about the old technology with its pros and cons.

As an example, I always assumed that the radiators were always just full of steam while running, but the systems actually work by cycling between steam production and condensation phases. There's an alcohol filled bladder at the base of every radiator that boils and expands when the steam fills the radiator, sealing off the flow at that point, forcing the steam to route around to the next radiator. Once all the radiators seal off the pressure in the system rises, triggering the boiler to shut down. The water condenses inside the radiators as they emit their heat and cool, the bladders open, the water drains back down to the boiler, and if the home temp is still low the cycle starts again. Who knew?

For now we're actually planning on keeping it around while it's all in good working order.
