@Danny_naj @Robotbeat I had an asymptotic scan that showed a massive prolactinoma pressing against my optical nerve, eating away at the bones in my sinus column, and pressing on my brain.

Got on Cabergoline and it’s shrinking. Was glad to find that before my vision started going or worse.

@Chronodendron @nealenrick My wife has points and accounts everywhere always trying to manage a discounted or free book, so I just have her buy my books for me and she keeps the points. Win-win.

[Mike Petty @mpetty423]

@smaashhhley @CensoredLeak Nope, that’s just your irrational framing.

If we sit down, look up the statistics for safety, watch some videos, and they still want to do it and I’m satisfied it runs a lower risk than a soccer tourney, then the simple risk assessment is a go. You should teach this to your kid

[Mike Petty @mpetty423]

@smaashhhley @CensoredLeak So you just encourage your kid to be a mute because their brain isn’t developed yet, so screw any preferences or thoughts they have, right? Like why even talk to out interact with your kids until they’re 25 then, right?

[Mike Petty @mpetty423]

@smaashhhley @CensoredLeak My tiny kid jumped off a cliff strapped to this guy’s chest. The first thing he said when they landed the BASE jump was “Again! Give me sister’s turn too!”

Fork your dependencies, trim them to only your use case, never update unless it breaks for your users. I’ve been vocal about this for 10+ years. I’ve always said that updating is way riskier than latent bugs (which can be tracked and CVEs monitored).

If you are updating a dependency, it’s on you to analyze every single commit in the full transitive set of dependencies. If you dont see anything compelling, dont update!

I remember at HashiCorp once in awhile an engineer would try to update a dep or replace a DIY lib with an external one and id always ask “show me the commit we need.” Dont update for the sake of it.

Feeling pretty swell about this mentality with all the supply chain attacks happening.

@HazelM97249481 @JackLinFLL @HotAsPuck Unless you're trained and prepared, if someone silts up a cave, you're diving in chocolate milk with no visibility and you'll just swim around in circles trying to find a way out until you run out of air.

@America1stDem @Noahpinion I actually got polled for this, I think. Exact questions not too long ago. What you’re describing here definitely doesn’t match why I answered unfavorable to both.

[Mike Petty @mpetty423]

@Noahpinion I said this once to a Slovakian grandpa, but used Russia.

He said “no, the non-Russian states in the USSR did all that”.

He said in the old country we had a joke about Russian engineers:

“What doesn’t buzz, and doesn’t fit up your butt?”

“A Russian butt buzzer!”

@xwanyex The altimeter is vestigial and the warning siren stops functioning as they outgrow it.

@bumbadum14 It’s illegal to sell in the US. An unelected committee decided they were unsafe.

We had one that was basically a padded three sided box we just plopped between us.

As a dad I loved it. I would’ve hated a bassinet next to mom. I want to see middle of night baby too!

[Mike Petty @mpetty423]

@GrantSlatton Exactly.

I have gone to the same grocery store for 20 years now.

Could you just recognize my face and not complain if something weighs an ounce more than it should, or not call an associate over if my movement blocked the camera for a microsecond?

The scariest finding in this paper: the subjects couldn't tell it was happening.

UPenn ran this study on 48 healthy adults. One group slept 8 hours. Another slept 6. Another slept 4. For 14 straight days. They tested cognitive performance every 2 hours from 7:30am to 11:30pm.

The 6-hour group's reaction times, working memory, and sustained attention deteriorated on a near-linear curve. By day 14 they were performing at the same level as someone who hadn't slept at all in 48 hours. The 4-hour group hit that threshold by day 6.

Here's the part that should unsettle everyone who thinks they "do fine" on 6 hours: the subjects' self-reported sleepiness flatlined after the first few days. Their brains kept getting worse. Their perception of how impaired they were stopped updating. The cognitive decline was invisible to the person experiencing it.

The researchers found a hard threshold. Any wakefulness beyond 15.84 hours in a day produces cumulative neurobiological cost. That cost compounds every single day you exceed it and does not reset with a weekend of sleeping in.

About 35% of American adults sleep less than 7 hours a night. 40% of those get 6 hours or less. In 1942 that number was 11%. We built an entire professional culture around a sleep schedule that this paper says is functionally equivalent to pulling consecutive all-nighters.

"I'm fine on 6 hours" is the most common response to sleep research. The first thing chronic sleep debt destroys is your ability to notice chronic sleep debt.

@guy_pharm @CalebRodden1 @uncledoomer You could rent an ROV to go down there and be in the water in a week. They're fairly common and not all that expensive to rent (compared to the prize here).

Four humans are about to fall into a 10,000°C wall of plasma at 25,000 mph with a heat shield NASA knows is flawed. Tomorrow evening. Off the coast of San Diego.

Orion hits the atmosphere at 36 times the speed of sound. The air can't move out of the way fast enough, so it compresses into a shockwave twice as hot as the surface of the Sun. The plasma ionizes the surrounding air and blocks all radio signals. For several minutes, the crew is falling faster than any humans have ever traveled inside a spacecraft, and nobody on the ground can talk to them.

The heat shield is 186 blocks of a material called Avcoat glued to a titanium skeleton. It works by charring, melting, and disintegrating on purpose. The destruction of the outer layer is the cooling mechanism. There is no backup system. No redundancy. The heat shield works or the crew doesn't come home.

The Artemis I heat shield came back with over 100 locations where chunks had ripped off. NASA spent two years figuring out why, concluded it was gas pressure building up inside the material during reentry, and decided not to replace the shield. They changed the flight path instead. Steeper angle, less time in the danger zone. NASA Administrator Jared Isaacman said publicly that this approach "is not the right way to do things long term."

The capsule will slow from 25,000 mph to 17 mph in thirteen minutes. Parachutes don't even deploy until the last four. Everything before that is managed by a curved piece of titanium and glue entering air twice as hot as the Sun.

Tomorrow at 5:07 PM Pacific, San Diego might hear a sonic boom. That sound is four people betting their lives on NASA's math being right.

@TheLastNeocon I once answered on vacation and started getting an earful from the school

I said “I’m probably the only person that picked up or didn’t hang up on you today. Don’t take my caring about my kid and not hanging up as an invitation for you to let out all your frustrations out on me”

[Mike Turitzin @miketuritzin]

A programming lesson that's been hammered into my skull is to not try to create a general system until you've implemented AT LEAST a handful of one-offs the system is supposed to support.

Otherwise you waste endless time fighting with and refactoring your "general" system.

@AlecStapp Wait until your kid tries Amira. My child hates iReady. It’s horrible, but it’s predictable. Same wait after every question. Amira is so unpredictable in what it does makes my son want to rage quit school. He comes home and hits the punching bag like a pissed off mini Tyson.

[Mike Petty @mpetty423]

@koalakitch @VicVijayakumar Wow, a triple reply!

Guess I touched a nerve.

I prefer to talk to my kids with my undivided attention and looking them in the eyes rather than looking at a pan.

Have a good one. We both seem to care much about our kids. Too much to be drug into some silly breakfast thing.
