I'm a beardless unix greybeard who loves dabbling in new computer languages.

I'm also fascinated in the psychology of belief.

Philosophically a skeptic, but I don't attend their services :-)

emmelaich··on Log File Viewer for the Terminal
I sense an opportunity for you.
emmelaich··on Ubuntu 26.04 Ends 46 Years of Silent sudo Passwords
This is a good change.

To reduce the length exposure, the software could randomly show multiple asterisks per key-stroke. I think Lotus Notes did this. Of course, this may lead to people suspecting keybounce.

I've successfully shoulder-surfed someone to discover their password (in response to a sudo prompt) by watching their hands and fingers. So if the person is close enough, having echoed stars or not makes no difference. It was long password too, but contained two whole lowercase words.

emmelaich··on Denmark was reportedly preparing for full-scale war with the US over Greenland
Iran has been in a war with the USA since at least 1979. I was about to say "soft war" but that would be ignoring all the deaths.

This is one battle of many and the USA will win it. Whether it is warranted or whether the USA will win 'the war' is another thing.

C'mon people, no NATO member is going to attack any NATO ally. Be real.

AAA rates Tesla Y better than most.

emmelaich··on Denmark was reportedly preparing for full-scale war with the US over Greenland
The idea that the US would attempt to take Greenland by force is utterly ludicrous.
emmelaich··on Building a Shell
I don't know how real you want -- those criteria are probably self contradictory :-)

Marc Rochkind's book Avanced UNIX Programming implemented a basic shell, through iterations. You can see the first at e.g. here https://github.com/gmarler/AUPv2/blob/master/c5/sh0.c

It might be a bit old too. The book is very good but again, quite old. There seem to be free copies of it on the net.

BTW, does anyone know if Marc Rochkind is alive? His site basepath.com seems to be for sale :-(

With AI they good probably replicate it perfectly. For good and bad.

Oh man, Barney Miller, Night Court, WKRP,... golden age of US TV dramedy.

Agree, Whedon's script is essential to the popularity. I'd love it happen tho if they can do a good enough job. As well as River etc, I'd like to Shepherd Books back story.
emmelaich··on Excel incorrectly assumes that the year 1900 is a leap year
You may know this but originally they were 'correct' because the start of the year was March.
emmelaich··on Malus – Clean Room as a Service
Same argument applies. Driving slowly for 1km 0.01 under the speed limit, over legal blood alco limit is safer than driving at the speed limit for 10kms just under the alco limit.

It's very easy to come up with thought experiments to show that technically illegal scenarios are not necessarily more dangerous than some legal scenarios.

The law is often made to be easy to apply, not for precision. Hard to see how anyone could see otherwise.

That's not say that the laws are necessarily problematic. You have to draw the line somewhere.

emmelaich··on How we hacked McKinsey's AI platform
There's a sort of prisoner's dilemma. If you make a fuss you'll get branded as anti-progress and sidelined. If you put your head down and just do what you're told you're a team player and will probably survive.

Aside, there's a lot of stuff online re McKinsey. I suggest searching HN plus also search "Confessions of a McKinsey Whistleblower" in your fave web search engine.

My favourite was the LRB article "When McKinsey comes to town" -- see https://news.ycombinator.com/item?id=33869800

emmelaich··on Remotely unlocking an encrypted hard disk
You don't need a robot arm, just mimic a usb keyboard.

https://pikvm.org/ and similar exist.

This is maybe not as good as the article solution, because it requires you to secure the pi too.

emmelaich··on Show HN: I built a sub-500ms latency voice agent from scratch
Regarding 2, I believe that talking on mobile phones drives older people crazy. They remember talking on normal land lines when there was almost no latency at all. The thing is -- they don't know why they don't like it.
emmelaich··on How to talk to anyone and why you should
I've done some Uber driving. Chatting in a car is great because there's no awkwardness of whether to look at one another. I've met some really interesting people, from all backgrounds. I can recommend it if you have time to spare and want to chat with people.

Not everyone wants to talk but you can pick up on that pretty quickly.

emmelaich··on I am directing the Department of War to designate Anthropic a supply-chain risk
Did you edit it to fix it? Is HN refusing to include the period as part of the URL?
emmelaich··on What does " 2>&1 " mean?
Try it without the `cat` and tell me what you get.
emmelaich··on What does " 2>&1 " mean?
A gotcha for me originally and perhaps others is that while using ordering like

   $ ./outerr  >blah 2>&1
sends stdout and stderr to blah, imitating the order with pipe instead does not.

   $ ./outerr  | 2>&1 cat >blah
   err
This is because | is not a mere redirector but a statement terminator.

    (where outerr is the following...)
    echo out 
    echo err >&2
emmelaich··on What does " 2>&1 " mean?
Yep, there's a strong unifying feel between the Unix api, C, the shell, and also say Perl.

Which is lost when using more modern or languages foreign to Unix.

emmelaich··on I baked a pie every day for a year
Actually closer to π and matches the more sensible date format.

(Yes this is worth fighting over!)

emmelaich··on Jimi Hendrix was a systems engineer
I've not listened to that song much at all. I am however obsessed with Machine Gun which has all those elements and more. Maybe I'll have a re-listen to SSB.
