Rediscover··on A bear case: My predictions regarding AI progress
FWIW, local Yellow Cab et al, in the U.S., has been doing that for /decades/ in the areas I've lived.

Rx medicine delivery used to be quite standard for taxis.

Rediscover··on Making my first robot as a software engineer
Much great info about JST connectors, heck the whole website is great:

Rediscover··on Funding restored for man-page maintenance
Try comparing OpenBSD (or Solaris or ...) man pages to those on Linux?

The one for traceroute(8) has some great commentaries on the sample output ("God only knows what's going on with 12."). It's a personal favorite.

Rediscover··on Ask HN: Life-changing purchases since 2020? (Under $100 and under $1000)
This year I treated myself to a benchtop power supply for home use.

I've worked with electronics (mostly embedded hardware and lower-level software) for >3 decades professionally where bench supplies are everywhere. My hobby use saw me using various wall-warts, regulators, batteries, and hijacked/hacked-up desktop PSUs as I always thought owning a dedicated supply would be a waste. Purchasing other TE had higher priority.

Surprise!! Life is so much better, unbelievably, having my own benchtop power supply for idiot stuff that I would not have invested the time and effort to try previously. I was adding a fan to a project yesterday so I spent ~2 minutes testing candidates for audible noise when using 12V and 24V at various currents - not a necessary part of the selection process for the expected use but nice when it is low effort (turn on PSU, select output channel,dial in voltage, dial in current, done).

> ... any door ... wouldn't lock behind me.

You are not alone with that precaution. Ages ago, before plastic gift cards were ubiquitous, I used to quest/urbex with shims of thin aluminum trimmed to door jamb size (making them harder to detect).

The buddy system also was used - "You stay on this side, I'll go through and test it can get opened from the other side."

Extremely useful when entering campus/city steam tunnels that may not have another good door for hundreds of meters (the tunnels were secured to prevent access to the structures they connected).

Rediscover··on Why and how we’re migrating many of our servers from Linux to the BSDs
Slackware. It has always had a bit of *BSD flavoring in it, too.
Rediscover··on Leonard Cohen: The Man Who Saw the Angels Fall
No one has mentioned it, the album "I'm Your Fan" is a collection of LC covers by (album order): R.E.M., Ian McCulloch, Pixies, That Petrol Emotion, The Lilac Time, Geoffrey Oryema, James, Jean-Louis Murat, David McComb & Adam Peters, The House of Love, Lloyd Cole, Robert Forster, Peter Astor, Dead Famous People, Bill Pritchard, The Fatima Mansions, Nick Cave and the Bad Seeds, & John Cale.
Rediscover··on James Earl Jones has died
James Earl Jones did the intro for the book "Poetry [to read] Out Loud." His voice is very present in those written words. Great stuff!
Rediscover··on Show HN: Anyma V, a hybrid physical modelling virtual instrument
Thank You very much. It is extremely nice that a virtual piece of hardware such as this is created AND shared.

High regards!

Rediscover··on GenBook RK3588 – Modular open-source ARM laptop with DIY expansion capabilities
I don't know but it slightly reminds me of the Cool Pi laptop:

Rediscover··on Reverse engineering a restaurant pager system
Kerouac aside, wasn't it the yippies (not yuppies) that were doing the Pentagon performance?

ISTR yuppies were years after the Youth International Party (and quite different).

Anyone?

Rediscover··on I bought an encyclopedia
I really enjoyed John Muir pubs like How to Keep Your Volkswagen Alive: A Manual of Step by Step Procedures for the Compleat Idiot. They are available for a handful of vehicles (the Subaru one is a favorite of mine). Available at a used bookshop or new.

Great drawings, useful for non-motor-heads. The Sub version has info like resuscitating a drowned lizard :)

Avoid if You hate R. Crumb style drawings and hippies.

Edit, adding: you don't need a specific one to gain great knowledge.

Rediscover··on Deterioration of local community a major driver of loss of play-based childhood
Such a great use of group chat. Thanks!
Rediscover··on Research as leisure activity
It used to be the nearest university (especially if they have an adjoining curriculum), sometimes a local business. Don't be afraid of microfiche for older pubs. Don't be afraid to introduce yourself.

I still find libraries pretty useful while simultaneously being amazed at the quantity of papers online - I have found papers I would have nearly killed for decades ago now online at faculty pages of my favorite researchers. I'm guessing online is better for most, especially when coupled with browsing faculty pages for the author of your random linked papers. Also, look for citations listings that include authors of papers You like (it's printed and at your local research/eng lib for older obscure authors).

Before Eternal September and still today (though maybe less?), sending an intro email to someone that is studying a subject You are interested in is often useful (possibly better for niches). I'm guilty of not responding in a timely manner.

Probably Semi-OT: look at some indexes for CoEvolution Quarterly.

Rediscover··on Ask HN: What's your favorite everyday app or product?
Now that it's mentioned... Yeah, Termux. I use it all the time. I used to always have a small laptop and/or a wearable with me constantly, now those are often still with me but Termux (with the Hacker's Keyboard) has reduced my carrying of those. I possibly spend more time (on my phone) in Termux than all the other apps combined (including the browser "apps").

Thanks for alerting me to my usage (reliance?) of it.

Bonus: Most everything also syncs easily, for me, with my more traditional computers with rsync or scp from/to a Termux session.

Rediscover··on New startup sells coffee through SSH
Thanks for posting the link.

Shift+Insert has worked for decades in the XTerms I've used. It's bound in my muscle memory and is a source of frustration, for me, when attempting to use non-X Widows GUIs or odd-ball "terminals"/programs/foo.

Rediscover··on Run0, a systemd based alternative to sudo, announced
Main here, with *BSDs or Yocto-based right behind.
Rediscover··on Self-control signals and affords power
Good quote from Neil Peart. Roll the bones
Rediscover··on Reverse engineering a cable modem and turning it into an SDR
FWIW, some Panasonic laptops still have real (non-USB, as opposed to their internally-USB-based) RS-232 ports. Just saying...
Rediscover··on AT&T applies to end obligation to service landlines in California
If anyone is wondering about first reponders' use of land lines, that necessity is to be alleviated with the United States setting aside some spectrum in 700MHz back in 2012.

Do a search for "band 14" - here is something to look at: FirstNet

https://www.firstnet.com/coverage/band-14.html

[My household used to be required to have a land line ages ago and I still pay (slight) attention to things in this space. I do not have first-hand experience any more with such matters.]

Rediscover··on I just wanted Emacs to look nice – Using 24-bit color in terminals
Apologies, I meant to add more saying I could not get a remote machine to invoke the local emacs reliably. I got close with hacking up emacsclient to ssh back, but was eventually stymied by new network policies at $JOB and eventually settled for the above.

db48x has a great answer below.

Rediscover··on I just wanted Emacs to look nice – Using 24-bit color in terminals
Probably not the answer You are looking for...

Try some variant of this in your remote .bash_profile or what-not:

  if [ "$PS1" ]; then
      export PS1='\h:\w\$ '
      if [[ "x${TERM}" = "xeterm" || "x${TERM}" = "xeterm-color" ]]; then
       function set-eterm-dir {
         echo -e "\033AnSiTu" $(whoami)
         echo -e "\033AnSiTc" $(pwd)
         echo -e "\033AnSiTh" $(hostname -f)
       }
      PROMPT_COMMAND=set-eterm-dir
    fi
  fi
Now, locally, invoke M-x ansi-term, then within the ansi-term ssh to the remote machine. Change dirs, hit C-x C-f to open a file in the current (remote) directory.

See also the ansi-term hints on emacswiki

or the comments in /usr/local/share/emacs/*/lisp/term.el

Edit: formatting

Rediscover··on Compression Attached Memory Modules may make upgradable laptops a thing again
Let's Note series. I've only seen it branded Toughbook in North America.

I love that series, especially those from your laptop's era.

Edit: Let's Note are much more durable than "standard" notebooks.

Rediscover··on My SBC Collection
That seems not a niche feature from my view...

Maybe it's a feature that isn't often advertised (amd64 machines excepted). I find it frequently in the datasheets (and then verifying with schematics and testing).

Another non-advertised thing is "real" LVDS on the same physical pins as MIPI-DSI. Again, datasheets+schematics.

Rediscover··on Operation Snow White
See also Dave Touretzky's homepage at CMU for a great take ("wacky") about Scientologists, and them appearing on the Carnegie Mellon campus.

Oh, there's talk of DMCA, aviation, and Lisp on that page, too.

Rediscover··on The Art of Electronics (2015)
2nd ed, chap 12, Construction Techniques, is missing from the third ed. Or I'm blind, but I don't see it here.
Rediscover··on Ask HN: What's your "it's not stupid if it works" story?
Lynx is my most-used/favorite browser. I get variations daily of "your browser is unsupported" messages that almost always go away, without website degradation^1, once I have lynx self-report as "Mozilla" - argh, white-listing.

^1 Excepting javascript, of course.

Rediscover··on Researchers uncover on/off switch for breast cancer metastasis in mice
As much as I dislike many aspects of living in most of both Ohios (NE (which, to me, should be Cleveland/Akron/Canton/Kent/Youngstown/PGH/Buffalo),vs the rest of the state), I am super impressed with the leniency (latitude?) tolerated in that place re: "academic freedoms," while not going [dipshit] (ok, I cannot describe or conceive of a more comprehensive term, my bad, my apologies).
Rediscover··on Chimera Linux
I suspect two of the many reasons for GNU usage were

(1) crazy command options (it only takes one or two to ease your workflow over the what the system distro supplied, plus the same behavior for the same flags across platforms)

(2) the lawsuit (probably an understatement - it was Serious back then)

Edit: added "usage" for clarity, s/statment/statement
