0xDEFACED··on On the pronunciation of “fsck”
I had never considered that there might be other ways to pronounce it. I’m gonna start saying it “zhee-rá” now
0xDEFACED··on With Firefox on X11, any page can pastejack you anytime (middle button paste)
> And middle click is for opening tabs.

Learning that you can middle click on the back/forward/refresh buttons to open the previous/next/current page (respectively) in a new tab was a game changer for me

0xDEFACED··on Why do patients leave against medical advice?
My ~18 month old son is medically complex, and his pediatricians send him to the ER basically every other week. ER docs run a bunch of tests, shrug and say LGTM and send us home. The hospital is an hour away, and they never get any closer to figuring out what the problem is (just follow up with X specialist in Y months). My wife and I are sick of it, but we’re worried that if we don’t take him in when they tell us to that CPS might get involved. So off we go, wash rinse repeat.

All of that to say, if someone wants to leave early, I get it.

0xDEFACED··on Pulsifer v. United States, a case that turns on a federal law’s use of “and”
Seems the discrepancy is more related to whether the “not” is applied like:

  !A && !B && !C
or:

  !(A && B && C)
which the informed readers knows is equivalent to

  !A || !B || !C
So a little more nuanced than what “and” means. This article would have been great to use in a lesson in the logic unit when I used to teach geometry.
0xDEFACED··on Snowden leak: Cavium networking hardware may contain NSA backdoor
Computerphile has a video about this algorithm and its potential backdoor, it’s a great watch.

0xDEFACED··on Researchers have found that micro-spikes etched into titanium rupture microbes
Thanks for adding a new word to my vocabulary! I knew that silver had antimicrobial properties but didn’t know the phenomenon had a name.

I think the material described in the article is a bit more novel than you’re giving it credit for though. The article has an image showing an intact bacteria on polished titanium next to a ruptured bacteria on this new surface. My guess is that the increased surface area of this new material allows for the oligodynamic effect to act more quickly.

0xDEFACED··on Chess as a case study in hidden capabilities in ChatGPT
Very cool! I wonder how much performance might improve if you provided the FEN[0] for the game’s position after each move instead of, or in addition to, the move list.

0xDEFACED··on UChicago scientists see first evidence of 'quantum superchemistry' in the lab
> Another consequence is that the final molecules share the same molecular state. Chin explained that the same molecules in different states can have different physical and chemical properties—but there are times when you want to create a batch of molecules in a specific state. In traditional chemistry, you’re rolling the dice. “But with this technique, you can steer the molecules into an identical state,” he said.

Is this “state” referring to left/right handedness of chiral molecules, or is this some other property? Or both?

0xDEFACED··on My favorite Vim oneliners for text manipulation
I work with python a lot and recently learned you can use this

    %! python
If the buffer you have open is a python script. Doesn’t work great if you have a bunch of stdout to read, but good for quick tests
0xDEFACED··on Ask HN: Where do you buy your coffee beans?
Here’s a few of my favorites from Virginia!

0xDEFACED··on Why not tell people to “simply” use pyenv, poetry or anaconda
If using apt, you can add the deadsnakes repository which allows installing the other versions of python3 not included with your linux distro. Then you can install them with

  sudo apt install python3.X
I also recommend similarly

  sudo apt install python3.X-venv
which allows you to create venvs with whichever python version you have installed

  python3.X -m venv .venv
0xDEFACED··on Ask HN: What are some “trivial” achievements you feel satisfied about?
My son is a ventilator patient as of recently, and his ventilator has a usb port on the back that can be used to export the data. According to the manufacturer, the exported files can only be viewed using their proprietary software, which they only distribute to trained medical professionals.

Long story short, with a little digging I found the spec for the file format and was able to write my own parser.

0xDEFACED··on Ask HN: What are some of the best documentaries you've seen?
It’s 10 years old, but I didn’t see “The House I Live In” in any of the previous threads. Its an amazing look at the history of The War on Drugs, and its impact on the criminal justice system and human rights in the United States.

0xDEFACED··on Apple Removes SIM Card Tray on All iPhone 14 Models in U.S.
I see this leading to a huge spike in the prevalence of SIM-swapping scams. I can’t remember the last time I needed to have my carrier move my number from one SIM card to another, but if this becomes the norm I’ll need to ask them do it for me every time I get a new phone. Or am I missing something?
0xDEFACED··on How Tardigrades Bear Dehydration
Tardigrades are incredible creatures! Resistance to dehydration barely scratches the surface of their durability feats.

0xDEFACED··on Nano-nonsense: 25 years of charlatanry (2010)
My freshman year of undergrad I took a nanoscience course as an elective. Through that, i found out that the department was in the final stages of creating a Nanoscience major, and since the prerequisites lined up with my primary major (engineering) I decided to go for a double major.

If I could do it over, I would stay away. The subject matter was fascinating, but was also a discontinuous hodgepodge of nano-related topics from physics, chemistry, and biology.

Things may become more organized as the program matures, but looking back it felt more like a 4 year exploratory to prep for grad school than a Bachelor of Science degree.

0xDEFACED··on PayPal phishing scam uses invoices sent via PayPal
I received one of these a couple days ago and was curious, so I went to paypal’s password recovery to see what it would take to reset my password. I was shocked to see that providing my SSN (which I don’t really consider private) was one of the options. Quickly changed the email on my account and dug around in settings way too long looking to enable 2FA
0xDEFACED··on Django 4.1
>That kinda defeats the whole purpose of an ASGI app.

Unless I’m missing something, wouldn’t an async ORM provide significant benefit for apps with an internet-based DB connection? I would think the underlying DB ops would be much faster than sending a request and waiting on a response.

0xDEFACED··on Ask HN: I love programming but hate the industry. Can anyone relate?
Do you remember what major he switched to?
0xDEFACED··on IKEA Instructions for Algorithms
What makes this tricky is that the public and private keys reverse roles when signing versus encrypting. Having these keys represented by different objects (physical locks or keys) depending on the usage can potentially make things more confusing.
0xDEFACED··on Show HN: I Made a Magic Trick
Learning that shortcut was a game changer for me. There’s a similar shortcut for the other google apps too (e.g. sheet.new)
