axiolite··on Sony DTC-700 audio DAT player/recorder
ATRAC was just to avoid the onerous MP3 license fees, AND lock-in consumers.

Sony is all about NIH. They never release a product unless it uses their own proprietary something-or-other. Remember memory stick? Hi8? UMD? PS Vita memory cards? MicroMV? MiniDisc? HiFD drives? SuperAIT? AVCHD? Why do you think DAT didn't use some other existing tape format like Digital8?

axiolite··on Cloud-forming isoprene and terpenes from crops may drastically improve climate
Clever, but no. This is about cloud formation, and doesn't indicate any (significant) increased chances of precipitation.
axiolite··on Get PC BIOS back on UEFI only system
From the project page: "Boot FreeDOS, Windows XP, and Windows 7"

Additionally, it was just 3 years ago that memtest86plus finally got a UEFI version. That was painful for a few years there. (Though the 4GB RAM limit would have made this not an ideal solution.)

I'm sure there are other such self-hosting utilities that haven't been and may not be ported/rewritten to work under UEFI.

axiolite··on How the Sun Enterprise 10000 was born (2007)
> The Sun box was not 800x faster at anything than a single x86 box.

You don't buy enterprise gear because it's economical for bulk number-crunching... You buy enterprise gear when you have a critical SPOF application (typically the database) that has to be super-reliable, or that requires greater resources than you can get in commodity boxes.

RAS is an expensive proposition. Commodity servers often don't have it, or have much less of it than enterprise gear. Proprietary Unix systems offered RAS as a major selling point. IBM mainframes still have a strong market today.

It wasn't until the late 2000's when x86 went to 64-bit, so if your application wanted to gobble more than 2GB/4GB of RAM, you had to go with something proprietary.

It was even more recently that the world collectively put a huge amount of effort in, and figured out how to parallelize a large amount of number-crunching problems that were previously limited to single-threaded.

There have been many situations like these through the history of computing... Going commodity is always cheaper, but if you have needs commodity systems don't meet, you pay the premium for proprietary systems that do.

axiolite··on Tmux – The Essentials (2019)
You included no arguments. You only hinted that something is "somehow" more complex and less capable. Analogies usually help people understand things. I don't see why you're offended and obstinate, but you can of course keep it up if you like. Have a nice day.
axiolite··on Tmux – The Essentials (2019)
I was illustrating that the parent comment was "lacking any arguments."
axiolite··on Tmux – The Essentials (2019)
I find most of shellcheck's opinions quite arbitrary.

Wider shell compatibility is a good reason to use backticks. Avoiding nesting is always possible. Quoting may be a concern in more complex usage. But yes, I know well, and often also use $( ) syntax.

Making a lot of noise about use of (the shellcheck author's) non-preferred syntax, which works perfectly fine in a given context, is a design flaw that renders shellcheck useless to me. I'm perfectly capable of finding an opinionated pedant on my own who will also critize the syntax I use (with little or no justification), and offer no actual help...

axiolite··on Tmux – The Essentials (2019)
I use backticks in shell scripts all the time. Meanwhile, I've never had a legit use for: Ctrl-y so that's my tmux escape.
axiolite··on Tmux – The Essentials (2019)
Same reasons you might need Ctrl-a instead of Home...

1) Some keyboards don't have it, or have it in an awkward place. Most Android on-screen keyboards don't have it (good time to plug Hacker Keyboard). The gestures on Blackberry (e.g. Android) physical keyboards act like scroll-wheel movements rather than cursor keys.

2) Some shells/systems/terminal emulators/some TERM= settings/etc. just don't handle cursor or home/end keys in the console, and instead splat out garbage like: ^[[C^[[D^[[7~^[[5~

axiolite··on Tmux – The Essentials (2019)
"I tried caviar but found I really prefer hot dogs..."
axiolite··on Tmux – The Essentials (2019)
It's a choice. tmux uses the "alternate screen" capability, the same way editors like "vi" do, which (according to man tmux): "preserves the contents of the window when an interactive application starts and restores it on exit, so that any output visible before the application starts reappears unchanged after it exits."

To change that behavior, put the following in your tmux.conf:

    set -g terminal-overrides '*:smcup@:rmcup@'
    set -g status off
axiolite··on Tmux – The Essentials (2019)
> * Smooth/fast scrolling goes away.

That was the first thing I looked-up how to fix (years ago). Put the following in your tmux.conf:

    set -g terminal-overrides '*:smcup@:rmcup@'
    set -g status off
axiolite··on Is bitcoin different from a cookie store coupon code without any cookie store?
Paper currency has some intrinsic value because there is a government that will accept it for debts owed (e.g. taxes, fines, ID cards, etc.). Not so for Bitcoin, nowhere is guaranteed to accept it. NOTE: I'm not the author.
axiolite··on Binocular Shot: A tribute to movies with inaccurate binocular shots
Meh on the whole thing. If your eyes aren't both focusing quite right, or you pull the two apart a little bit too much, you will see through binoculars in a figure 8, too.

It's a fools errand to take cinematography too literally as what a character can actually see. Should films also show the chromatic aberrations, adjust the camera to match the main character's eyes focusing, simulate blinking, eye 'floaters', and more?

And how about films in caves? Take away the last little bit of light for realism, so the audience is completely blinded, watching a black screen like the character(s)? Never mind that viewers of films don't get to smell, feel, interact with the world as they choose, as the actual character in the film would.

axiolite··on Residential Networking over Telephone
That copper requires upkeep, which is expensive. The maximum speeds are terrible by modern standards. Using the existing right-of-way (established for the copper lines) to install new fiber that will replace the copper, is the right move.
axiolite··on McKinsey unit will pay $123M to settle claims it bribed South African officials
US oil companies like ExxonMobile have survived on the international market just fine, despite the laws preventing them handing out bribes for the past several decades.

There are several examples of bribes being publicized and the guilty company losing out on big contracts as a result (e.g. from ECHELON spying).

axiolite··on The fight to ban gas-powered cars in the 1960s
Lead-acid power is what the EV1 came out with, so something similar to that could have existed in the 1960s. Cheaper vehicles would have been closer to golf carts or electric bikes, but it would have been possible.

Because EVs didn't have the range of gasoline vehicles, EV concepts in the old days usually included something like overhead catenary power lines, or in-road induction or other "3rd rail" type charging on freeways, in order to sustain longer trips.

Let's try to keep in-mind that 1960s cars were horrendously unreliable, not starting when you turned the key because they were too hot or too cold, requiring obscene amounts of maintenance, etc., so a trade-off of range in exchange for an immensely reliable vehicle is something many people would have been willing to make, too.

axiolite··on A free tool to quickly detect counterfeit flash (2017)

RHEL9 installer is 10GB.

It's a fact of life that titles can't always be a fully accurate description of the whole subject. Otherwise we wouldn't need the part that comes after the title...
axiolite··on A free tool to quickly detect counterfeit flash (2017)
Have you found cases where "f3probe --destructive" didn't work for you?
axiolite··on A free tool to quickly detect counterfeit flash (2017)
You can certainly return an item if the title of the listing was inaccurate.

In my experience, eBay won't "flag" dishonest sellers of counterfeit storage products, anyhow. I tried to get a listing selling counterfeit Samsung micro SD drives taken down, but eBay did nothing. I was refunded, but the unsuspecting will continue to be duped.

axiolite··on A free tool to quickly detect counterfeit flash (2017)
The subject of this topic, f3, will quickly probe the drive, determine the true size, and create a partition on it of the actual usable size. Using that partition, you will never lose any data. If you try to create a partition in the rest of the drive, it will be immediately corrupted, no tools will show it as good, you won't ever be able to get around to putting data on it to lose it.

Works perfectly fine for me. v125.3.0 with uBlock.
axiolite··on A free tool to quickly detect counterfeit flash (2017)
A few sellers on eBay are honest

  Description:
  This item is upgraded by 32 GB Pen Flash Drive to 2TB
  32GB-2TB, the actual capacity is 32G, the computer displays 2TB, the detection is also 2TB, more than 32G things can be stored, but not displayed.

  https://www.ebay.com/itm/234810575961
That's not bad. Most counterfeits I get are just 2GB so hardly useful. Still, the counterfeit firmware makes compatibility issues more likely, so better to buy one without the counterfeiting.
axiolite··on Inside an IBM/Motorola mainframe controller chip from 1981
> HTML forms are poorly reimplemented IBM terminals

In HTML forms you can SEE where the input fields are. You don't have to "PROTECT" the HTML document from warping. You don't have to hit a special key when an HTML document is larger than your screen.

And IBM manages to get credit for ALL the early computer technologies just because they're still around. Other block-oriented terminals certainly existed, and I'm glad they didn't catch-on...

axiolite··on Inside an IBM/Motorola mainframe controller chip from 1981
Ethernet (OSA cards) and Fibre Channel (FICON cards) are standard on z Mainframes these days. TCP/IP is standard on z/OS, CP (z/VM), AIX and Linux. Terminal emulators connect over TCP/IP, not RS-232 or coax. etc.

But still today:

- The character set for most OSes (not Linux) is EBCDIC.

- The terminal is form-based (like a web page, but with invisible input fields) rather than character based.

- You ALWAYS have to have key punch and card reader devices defined (even on Linux).

- z/OS needs proprietary FICON (not plain fibre channel) connections to emulated ECKD disks (not block based) on one of just a few SANs that support it.

- VSE still needs a TCP/IP stack (one of two 3rd party vendors) purchased separately.

- You need several x86 computers (HMC and two support elements) to manage or even boot-up a mainframe.

- You have to painstakingly configure virtual to physical device address mappings (IOCDS) before you can boot-up anything.

And more.

axiolite··on Decade of the Battery
> there isn't a remotely affordable consumer friendly solution for "I want these batteries to take over when my power goes out".

That's called a UPS. You can buy them in stores. Closer fit for this purpose might be solar-charging portable power stations, which are also COTS hardware that similarly costs a few hundred dollars each.

Anything more elaborate than that needs to be wired into your breaker box, requiring licensed electricians and inspections. Not terribly expensive, though. Installing an automatic transfer switch in your home is pretty common in rural areas with frequent power outages, for generator installations.

axiolite··on The rise of batteries in six charts
> I cannot reasonably run lengths of 110v extension cords down the block to charge a car overnight, and acquiring my own house with a garage is dramatically more expensive

You don't need a garage, just some sort of reserved parking space... There are plenty of weatherproof electrical boxes. It costs a bit of money to have a trench from your home to your car parking area, but far less than buying a house.

And that "110v extension cord" can supply 240V with just a change of connectors on either end (e.g.: 6-30p) allowing charging twice as fast.
