deepspace··on Show HN: Tome, aka Tom's Editor – a new command-line text editor
My TUI editor of choice is "joe". It allows you to freely assign keybindings through a config file. Comes out of the box with Wordstar, Vi and Emacs bindings, but it is easy to roll your own.
deepspace··on Turning an old car into a powerful generator
Hell, no, it is not safe. That box of Arduino madness is going to fail sooner rather than later, and destroy the motor, the person's house wiring or both.
deepspace··on Turning an old car into a powerful generator
Also, look into controlling the ECU directly instead of futzing around with mechanically controlling the cruise control (yuk).

And this really, really needs a proper RTOS and "software written by someone more professional than someone who tinkers with Arduinos", since malfunctioning software can destroy the engine and/or burn your house down.

For the same reason, it requires a proper PCB, not some yanky box of protoboard and wires.

deepspace··on Most UI applications are broken real-time applications
Someone has not told Microsoft | It is not as simple as that.

On some Windows machines with network-mounted drives, the File-Print-to-pdf dialog takes *minutes* to become responsive, even when all currently open files are on a local drive.

This is the kind of thing the author is talking about. The programmers of that dialog box probably just called a generic "open file dialog" library function, without researching its worst-case performance.

In turn the library writers probably blithely coded something like "check if all mounted drives are accessible", without stopping to consider the worst-case performance.

deepspace··on iOS 17 is available today
I would be happy if it stopped correcting "and" to "And" in the middle of a sentence.
deepspace··on Johnson and Johnson is getting rid of its script logo after more than 130 years
I am old enough to still know how to use a slide rule, but I have not used one in decades. I can also scribble in cursive, but I have not done that in years either.

At some point, I noticed that I rarely wrote down something, and when I did, it became instantly unsearchable and therefore as good as lost. For a while, I scanned my written notes, but as soon as swipe keyboards on smartphones became a thing, I just switched over to 100% digital notes.

So, yes, it is hard to imagine a use for cursive anymore. Good riddance.

deepspace··on FindMyCat – Open-Source Pet Tracker
Yes, this is mostly a solved problem for vehicles. I have a tracker in my car that does not even connect to the electrical system. It is a somewhat bulky brick with a battery that lasts 4–6 months. Smaller units are available, trading off battery life for size.

The cost of the device is less than $100, excluding the cellular data cost.

deepspace··on In a Git repository, where do your files live?
That was very informative, but I wondered if there is an easy-to-read reference somewhere about WHY git works the way it does?

I am old enough to have used SCCS, RCS and CVS extensively. Each had their faults, but Git is the only VCS I have used where dealing with merge conflicts is unintuitive enough that I sometimes end up with the repository in an unusable state. I am sure I am doing something wrong, but I would like to understand why.

The VCS that maps closes to the way my brain works is ClearCase. You essentially have a versioned file system, and you can set up a view to present any previous state of that file system. Of course, administration is a nightmare, it is not distributed, it is expensive, yada, yada. But when using it I always felt I knew exactly what was going on under the covers, which is not the case with Git at all.

deepspace··on Arm IPO to kick off today
> Acorn Archimedes

Newb /s

I cut my teeth on an Acron Atom in 1982, and upgraded to a BBC Micro (a renamed Acorn Electron) the next year.

But, yes, I never would have thought that, 40 years later, most of the CPUs in my house would still be derived from that scrappy British's company's designs.

deepspace··on When MFA isn't MFA, or how we got phished
That is more plausible. But the embellishment about the phisher knowing the layout of the office etc makes me think it was just straight up an inside job, with the employee willingly handing over the OTP and trying to cover their tracks.
deepspace··on When MFA isn't MFA, or how we got phished
There is also the bit about the phishers deep-faking an employee's voice. Yeah, right. That happened. /sarcasm
deepspace··on We built the fastest CI and it failed
That line caught my attention too, and it looked superficially true. I have certainly never purchased a tool based on a phone call from a vendor. However, that only pertains to cold-calling, which is the absolute worst way to sell anything.

Advertising is a trillion dollar market for a reason – it works. The trick is to find the correct message and media for the audience.

Effective advertising takes a lot of skill, a lot of money, or both. A large portion of HN posts (including this one) are contain "hidden" advertising, and they absolutely work.

I have purchased more than one developer tool based on reddit and HN reviews, which originated as posts by the seller. On the "lot of money" side, a poster in the arrivals tunnel at SFO is an excellent way of raising brand awareness; even for developer tools.

deepspace··on To make dishwashers great again? (2020)
I still use the pods in the main dispenser, for convenience, but after watching the TC video, I started dumping a spoonful of loose Oxyclean into the washer before closing the door. That also provides detergent during both cycles, and the difference in cleanliness is night and day.
deepspace··on Chicago’s parking meter disaster
As someone who purchased every edition of Microsoft Flight Simulator from the beginning, I am still salty about Daley bulldozing Meigs field in the middle of the night.

deepspace··on Kagi Small Web
It is such a weird experience to do a Google search on someone else's computer after being used to Kagi. I recently requested a small usability enhancement, and it was implemented within a few weeks. Zero chance of that happening with any other search engine.

The search results are consistently better than anyone else's, including DuckDuckGo, so I am, and will remain, a happy paying customer.

deepspace··on US broadband grant rules shut out small ISPs and municipalities, advocates say
That is what the small city where I live did. As a result, we get gigabit symmetrical service for the equivalent of just over US$20 a month.
deepspace··on Govt of Canada proposes a 4% Link Tax
The bill passed. Meta has already stopped allowing links to news on Facebook. This is just an announcement of the fee the government will be charging companies like Google and Meta for linking.
deepspace··on Show HN: Travel search engine calculating results in single digit ms
No results for Toronto. It was quick to return no results, though. Fast != Good.
deepspace··on STM32 Blue Pill as an Hid USB Keyboard
I just bought a 4G 4B for $75 Canadian. More expensive than before the pandemic, but not outrageous. Of course, once you add a case, PSU, cables, etc, you are over $100 again.
deepspace··on OnlyFans: Who is Leonid Radvinsky, the elusive owner of a porn empire?
I think, to a large extent, they don't attract decent talent. The sites are barely functional from a monetization POV.

OF, for example, leaves stacks of money on the table by not having a functioning recommender engine. OF artists are almost always discovered and promoted on platforms like Twitter, which DO have finely tuned recommender systems, but it seems like such an inefficient way of going about things.

deepspace··on Untouchable number
What does that even mean?
deepspace··on 50TB IBM tape drive more than doubles LTO-9 capacity
I used to work in the bulk storage industry and the running joke from 2005 until 2018 when I left was "surely this is the year tape will become obsolete".

Cold tier cloud storage absolutely has tape behind it. You can even send tapes to some cloud vendors.

Broadcasting is another giant customer. Companies like WBD have Exabytes or Zettabytes of digitized programming (movies, series, documentaries) which would be impractical to store on disk. The typical workflow is for the program scheduler to direct the robot to fetch the tape containing a program 24 hours in advance of the broadcast time and copy it to disk, then erasing the disk copy after broadcast.

deepspace··on An excruciatingly detailed guide to SSH (but only the things I find useful)
> I'm squinting at it throughout

Same here. I have anecdotally noted that many people, like myself, who were around in the days of actual green screen terminals and later green monochrome monitors are far less likely to prefer dark mode than younger people.

For me, the advent of color screens that made black-on-white text possible was a huge improvement in terms of readability and eye strain reduction, and I cannot imagine going back to the old ways.

deepspace··on Suppose I wanted to kill a lot of pilots (2020)
> Or, maybe, Munger figured out that what was viewed as obviously correct wasn't actually correct

Nah, looking at the floor plans, he was just optimizing for cost at the expense of user experience.

To rebut your anecdata with my own: My dorm rooms at college had large 5' x 4' windows that opened. The unlimited fresh air and view over the campus helped me keep my sanity while studying for a 4-year engineering degree. A windowless room would have driven me stark raving mad in the first year.

deepspace··on Old software keeping space missions alive
The article calls software from the 90s "old". Nobody used COBOL for mission-critical software at that time. There is embedded software I wrote in the 80s and 90s still running in the field, mostly written in C.
deepspace··on micro – A Modern Alternative to nano
Yes! The first word processor I used was Wordstar (under CP/M). My first programming environment was Borland Turbo Pascal. Later, I used "QEdit", which was configurable to use the wordstar keys.

When I finally migrated from DOS to Unix, in the early 90s, I was delighted to discover JOE. It is the first program I install on any new Linux or *BSD box or VM.

JOE has syntax highlighting and several other nice features these days. I have therefore never felt the need to get proficient with vi or emacs.

deepspace··on Railway Safety Posters (2022)
For shock value, the Canadian workplace safety ad featuring the chef comes pretty close: https://www.youtube.com/watch?v=noFCekWiUGE
deepspace··on Railway Safety Posters (2022)
The one with the bridge reminds me of the trestle scene in "Stand by Me".
deepspace··on LK-99 isn’t a superconductor
Yes, I was typing faster than I was thinking. I should have said Resistivity instead of Resistance and ohms.m instead of ohms/m. My point is still valid, though.
deepspace··on LK-99 isn’t a superconductor
Yes, that was my first thought. There are absolutely instruments which can directly measure resistance down to 10E-8 ohms/m or lower, and I would expect any lab doing research into superconductivity to at least have one of those.
