Not a very useful measure if a country has cheap and reliable publicly owned rental apartments. I would prefer rental because it's easier to leave.

Some projects can be done as part of university courses cheaply and slowly.

The action Groundhog Day. I liked both, and Retroactive, Palm Springs, Map of Tiny Perfect Things, Meet Cute, and Stargate SG-1 S04E06 "Window of Opportunity". Who invented the time loop plot the first time around?

Check out the similarly plotted Star Trek TNG S05E18 "Cause and Effect", and its equivalent Outer Limits 1995 S05E16 "Deja vu".

The keyboard is probably short-lived anyway, so a replacement is a good idea. Just take photos of every phase of disassembly and keep the parts and screws arranged on trays or something.

A repair is theoretically possible with silver paint applied to the damaged conductive paths in the switching film, https://lemmy.world/comment/14076165 , but all the other switches will remain old and unreliable.

You might check what AliExpress has to offer. My Lenovo Ideapad 530S's film-switched keyboard started malfunctioning at three years age. I replaced it even though it was melt-studded (?) in - plastic rods poke through the keyboard, their ends melted flat and wide. Some instruction video told me to cut the stud ends off with a chisel, but I used a mini drill. The most difficult part was to hold the keyboard pressed in its place with weights on sticks while doing a temporary re-melt of the insufficient rod ends with a soldering iron (I could have skipped that). After that, I covered the re-melted ends with epoxy for near-original strength. The repair was successful.

I once damaged a Microsoft desktop keyboard with water, and repaired the corroded membrane with silver paint designed to conduct electricity. I'm not sure if laptop membranes can be pulled apart like that.

 

The whole wash was estimated 72 minutes when it started.

It weighs the clothes by inertia in the beginning, I didn't overload, and the water (hot and cold) comes in fast through thick pipes, so there's no excuse for this.

How dumb must the program be to estimate one minute left in the beginning of the rinse cycle with two rinses and a spin cycle to go?

The building and presumably the machine were made 2018, and the maintenance log on the side says many repairs have been made since, so the software must have been updated many times already.

 

I just made a post copy-pasting images from another tab. All jpegs became pngs, for example 1.3MB became 6.4MB.

If I save the image first, then upload to Lemmy, it stays as a jpeg. What causes the pointless converting when copy-pasting? Can it be stopped from happening?

Who invented the modern computer look and feel?


  1. Vannevar Bush invented the Memex crowd thinking desktop environment with redundancy-merging hypertext wiki 1939–1945.

He had designed analog computers and founded the Manhattan Project that produced the first nuclear bomb.

Memex was to increase humanity’s collective wisdom enormously, comparable to the printing press revolution in science in the last few centuries.

“First do this,”

“then do that:”

“Massive progress in collaborative thinking!”

Memex as described by Bush in “As We May Think“

"enlarged intimate supplement to one's memory"

"mechanized so that it may be consulted with exceeding speed and flexibility"

"Wholly new forms of encyclopedias will appear, ready made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified."

"The inheritance from the master becomes, not only his additions to the world's record, but for his disciples the entire scaffolding by which they were erected."

(emphasis mine)

Memex remembers knowledge and its creation process to be immediately learned from and built upon. It self-organises, integrating added information to the common knowledge tree.

It was designed for crowd work on all human knowledge.

WWW does not remember - it works like a paper pile. You can’t see a mesh of associative trails running through WWW any more than through a paper pile. The mental scaffolding by which knowledge was erected is lost. You can’t drop a knowledge structure into WWW and expect any amplification to happen.

It was made for publishing, not processing.

Vannevar Bush squiggling alone in his outer brain about a shared outer brain:

He specified a desktop computer to host Memex,

and suggested a quaint working principle,

which nobody thought could possibly work.

John von Neumann replied:

Konrad Zuse already made it from ones and zeros - it’s fast and precise. Let me show you how to make one.”

Bush replied “It’s hideous and boring! Twiddling knobs is so much gayer than pressing buttons!”

"I tweak this - that there resists. I let go - it returns under the force set by this slider. I flip this clutch - these three start arguing, and it’s all chaos! It wiggles! Then you tweak the adjusters until order emerges. The point is collaboration.”

“It doesn’t matter which way you swing the data. All computers are born equal, so ours isn’t any worse”, explains Alan Turing.

“Also, we were being bombed when we made it, and beat Nazi Germany with it.”

“What will the machine do? Nobody knows. Is it thinking? Who cares? If it quacks, it’s a duck., says Turing.

“We’re selling them too. Can you afford to be without?”

U.K. Government drove Turing to suicide for his taste in companions.

Meanwhile:


U.S. military chose von Neumann’s architecture and made SAGE air traffic control computer for Soviet Russian bombers.

Inside the computer, bits of electricity were beamed off of red hot metal wires all the way to the display, X-raying the user.

Outside the computer, workers parked their cars.

They wanted reliability, so a backup computer ran in the background, ready to take over.

Meanwhile:


  1. Ivan Sutherland liked the pointable display and invented interactive computer graphics.

“See, when I scale the main part, all the sub-parts inherit the change. Then I start the simulation and we’ll see if the chair can bear the weight. Easy as C-A-D.”


  1. Douglas Engelbart, who had been inspired by Memex, looked at the new computers and the state of Earth’s collective intelligence.

He had a worry:

“What if an unforeseen danger is about to hit us? Can we solve the problem quickly enough? Doubtful.”

He had a vision:

"We should use computers to boost mankind's capability for coping with complex, urgent problems."

He worked at ARPA IPTO with master craftsmen orchestrated by J. C. R. Licklider, Ivan Sutherland (the CAD guy), and Robert Taylor. In 1968 they launched “The Mother of All Demos” on the oN-Line System (NLS), a collaborative desktop environment.

Douglas Engelbart mousing around with other users’ pointers while typing on a 5-bit chord keyboard.

Talking about the structure of knowledge in a real-time collaborative-editing wiki.

Team of programmers wiggling the server’s logic graphs with their mice. No twiddle knobs, only unfeelable pictures under glass.

Internet, then ARPAnet, has been up since then - it may be the most reliable machine ever made.

Moments later:

  1. Alan Kay working at the same ARPA IPTO designed the handheld computer Dynabook 1968. (He writes on Quora.)

“The best way to predict the future is to invent it.”

Unimpressed, the U.S. Congress fired ARPA IPTO in 1972.

Earlier, over the decades where the congress representatives live:

The Principal contaminants in used oil are Aluminium Dichlorodifluoromethane, Benzene, Antimony Trichclorotrifluorethane, Toluene Arsenic, 1,1,1-Trichloroethane Xylenes, Barium Trichloroethylene, Chromium Polychlorinated biphenyls Other PAHs, Cobalt Sulphur, Copper Nitrogen, Lead, Magnesium, Manganese. Mercury, Nickel, Phosphorus, Silicon, Sulphur and Zinc.

http://www.materialsciencejournal.org/vol7no1/environmental-impacts-of-used-oil/

Luckily a rich company, Xerox, immediately grabbed the project. Whew!

At Xerox PARC Alan Kay (the Dynabook guy) made a user-programmable desktop development environment virtual machine Smalltalk on the first modern personal computer Xerox Alto (“interim Dynabook”) 1973.

Children loved its learnability.

Users loved its understandability: Transparent meanings all the way down to what makes it tick.

https://www.youtube.com/watch?v=AnrlSqtpOkw&t=157s

"Doing with images makes symbols!”

It was highly learnable, user editable, and crowd collaborable in an unlimited number of persistent, shared workspaces.

It was supposed to make everyone fluent in computers in the same way that Ford Model T with its complete manual for disassembly, maintenance, and repair had birthed a generation of Americans fluent in mechanics who then went on to win World War II, to the Moon, and higher up skyscrapers than ever.

“Learn this as a child:”

“Do this as an adult:”

“Let’s do the same with computers?”, suggests Alan Kay.
