HocusLocus··on Sick of smart TVs? Here are your best options
How come no one has suggested tiny screens and huge Fresnel lenses like Terry Gilliam's 'Brazil'? Is this the wrong thread? If you place the apparatus in front of a window to catch the afternoon sun, it would also harness solar energy in an exciting new way!
HocusLocus··on Why don't people return their shopping carts?
Parked overnight at a midwest Walmart (when that was a thing) and got out to do something at 4am trying not to look like a predator. Ten carts were pushed over the embankment into the creek. Lifted them out and put them where they could be hosed off. What gets into people?

HocusLocus··on Just use a button
A whole generation of people who click all over to find places that do something. People have this problem where they feel 'proudly vested' in learning things that just weren't designed well.

10 years ago someone decided that dragging links is so much more important than selecting text, selecting text is scarcely possible. I'm going to have to fork a browser to give link-dragging the demotion it deserves. It was probably those DIV guys.

HocusLocus··on Can “second life” EV batteries work as grid-scale energy storage?
In an ice storm and cold cloudy snap that sweeps the country, NO lithium batteries will save the grid. I'm weary of this tunnel vision of the absurd. The only 'storage' that works is to pump water uphill with 'surplus' energy, and there is not and never will be a surplus. And these evaporartion tanks are on a scale that ecologists have to remember countless horror stories (eg., Glenn Canyon Dam). And of course there's always "mfft!" (another scheme with no numbers behind it so it's credible because I'm talking about it).

The last time there was anything rational on the table was Perry under the Trump administration's 30-day rule proposal ( https://www.nucnet.org/news/nuclear-is-vital-to-us-national-... ). It gave a hard industry incentive to any energy supplier who can have 30 days' fuel on site. This means nuclear and coal. This was no gimmick, it was the first time anyone faced reality about National Security as related to Energy for the grid and survival. And now AI datacenter yadda yadda, we're also talking about the luxury of keeping schools heated in Winter. Adverse weather even for a week is grid down game over for wind and solar. Proven natural gas are ~300 years, joy! As soon as they get around to sending pregnant whales across the ocean (losing ~20% of the gas-energy in cooling) it may even last 50 years! Before we have to go to endless war again.

HocusLocus··on Delete FROM users WHERE location = 'Iran';
Now do Cuba. The American Mafia was running Cuba by 1959 because, casinos and American tourism. Fidel Castro's revolution was genuine and did reflect the desire of most Cubans when it kicked the US Mafia out. The mafia expressed interest in ousting Castro and getting their casinos back. Bay of Pigs was a failed CIA+private mission whose motive was america:demorcacy:'communism' to which I add :mob. Las Vegas was their backup cope.

Then in 1962 suddenly another motive was added :USSR-missiles. The US blockade of Russian warships probably loaded with ballistic missiles on their way to construction sites in Cuba, was the closest brink of war yet. My Dad (ARMY) was on alert and packed to go.

With that resolved and no USSR missiles in Cuba the working motive for opposition fell back on (because Castro, Communism) and its economy was hobbled for years until neutral worldwide investors besides the USSR established ties. To this day Cuba is still on the edge with the lines shifting back and forth.

As has Iran since the Shah dynasty ended and American hostages were taken. So Cuba and Iran have lines stretching back into the distance. Probably you and I are young and it all seems so ancient. But Iran is a wealthy country now and (like us and the CIA) and it is now 'on our watch' to make sure money is not being funneled into the wrong places.

This nuclear thing annoys me but I'm a 'radical'. Aside from sweetheart deals and that 'other' country the US gave The Bomb by supplying their initial fissile material... since the USSR split anyone with MONEY has been able to acquire 1,2,3,+ bombs if they want them. "So and so is two weeks from having a Bomb" is generic Boomer slop to stoke fear and justify anything. And by all means if you have uranium, centrifuge uranium. And build out nuclear power.

Don't reply with an answer and place yourself in the crosshairs. But think on or find out for yourself, what number between 3% and 99% was Iran aiming for? If the number is on the higher side don't think in terms of [stupid] nuclear war, think in terms of money being wasted and having to deal with the most sordid people in the world to sell it. A bad direction. Things like this are both funny and sad, and hint at a world that might have turned out differently, better ( https://web.archive.org/web/20150518180531/http://en.wikiped... ). Time to revisit roads we had not taken.

I sit here in my cubicle, here on the motherworld. When I die, they will put my body in a box and dispose of it in the cold ground. And in the million ages to come, I will never breathe, or laugh, or twitch again. So won't you run and play with me here among the teeming mass of humanity? The universe has spared us this moment."

HocusLocus··on Ask HN: Has anyone else been unemployed for over two years?
I'm trying to understand Section 174 impact especially because your friend's persistence seems like a good litmus test that positive changes are afoot. Also I have a daughter who will be looking for R&D/R&E EE position when she graduates in 2026.

Needing to amortize expenses over 15 years puts a big damper on anything corps may be excited about today but with less than 100% assurance of in the long run? Restoring the pre-2022 regime for domestic expenses only is for the most part supporting domestic workers? So your friend is back in a more familiar job market... maybe college grads too? Thanks.

Modern equalizers on screen are most often parodies of the original they were designed from. How can you get excited about photorealism and shiny looking knobs and 'skins' when it's 'grab with grabber hand, hold mouse and lift or lower then drop' 30 times? Like a dumb child's simulation game.

I love EQs with many bands. In the real world I used to drag across the row of sliders with the knobs between two fingers setting a general curve during the first second of a song... in a single motion. Without looking. Graphic designers want rectangular EQ knobs. DJs want round ones. I wanted to manufacture round ones with spinnable outsides to max the speed of the curve-swipe.

HocusLocus··on React is winning by default and slowing innovation
I use a discussion board that has migrated from React to uber-React. Now the system has become completely hostile to saving local pages. Now any local copy when opened locally shows (then blanks completely) all visible content and mutters helplessly "Perhaps you followed an invalid link?"

But even more hostile is a discussion forum has replaced embedded message post times <time></time> with just useless plain "x ago" text and the actual timestamps for each has been hidden as React "props" magically shown by mouseover events by "class". Like "I'll show a picture of a timestamp if you really wanna see one."

An HTML-only copy is more than useless when it used to contain messages and times. A "Web, complete..." copy has message text in there but it blanks everything, sounds like the kind of bug someone would have fixed in a minute if they cared.

And they don't it seems. Like web architecture involves toppling furniture at random and too bad if you trip over something. Love it or leave.

Is this a React thing or an attention-to-detail thing? When I cannot easily save pages locally, I'll go elsewhere.

PS: It "looks" as beautiful as ever. A tad slower maybe.

HocusLocus··on Study finds gaps in evidence for air-cleaning technologies to prevent infections
No, I just know the mechanism (UV/spark) is missing and the air has no odor of it. I know the smell of O3 because an old boss had one of those cracking sparking monsters that projected blue on the ceiling when the light was off. It blew its power supply in short order and no one suffered ill effects, but no one missed it either.
HocusLocus··on Study finds gaps in evidence for air-cleaning technologies to prevent infections
My primary device is a 2010 Comtech (good luck finding one). It's just a voltage multiplier off of 110VAC( https://en.wikipedia.org/wiki/Voltage_multiplier ). I bought 8 $5/ea Chinese 'neg ion modules' and tied then to the back of the fan... they are parts to build into a much weaker device for cars. They will last longer (because they're resin sealed) and safer (12VDC supply) but by comparative output measurement I will need an array of 36 to match the output of the 2010 device. At $5 ea, this is doable. There are single power supply units more capable but I like the idea of 36 separate waterproof replaceable 12VDC things.
HocusLocus··on Study finds gaps in evidence for air-cleaning technologies to prevent infections
Breathing and sleeping in negative ionized air for 40 years. Just high voltage potential -7 to -10kVDC and spread carbon hairs (better than metal spikes) to launch it.

Walls and floors always have positive charge conducted from the ground outside relative to the air, no sparks means ozone in too small concentrations to worry about. Dust, smoke, bacteria and viruses stick to walls not the inside of lungs and the air is clean and odorless. You can shine a very bright flashlight through it in a dark room and see absolutely no beam. Every so often you sponge off the walls with strong cleaning solution. Latex paint stains easily near the device which is a subtle way of reminding you how germy it really would have been. Use plastic over walls near the device to save yourself some color matching and painting.

Over all these years, the most annoying thing has been other people trying to sell me HEPA filter solutions with screaming fans that need accessory replacement often. They insist I'm killing myself with ozone as a fear tactic. Few people sell just ionizers or sabotage the concept by selling weak/ineffective ones... because HEPA is big money.

Ionizers use tiny energy and no recurring supplies. Just make sure your electronics are grounded well.

HocusLocus··on Building the mouse Logitech won't make
Used a trackball since 1994. Desktop publishing and photo editing, if you've ever needed to position precisely and lift finger off the ball and click or mousedown without moving the focus again you'll just know.

Kensignton makes a good one with a scrollwheel ring around it, the ball XY is perfect though the clickers are so-so in longevity. Working without a physical middle click and two button software middle click emulation is frustrating sometimes.

HocusLocus··on Building a computer in the 90s (2019)
Apple Lisa was priced way too high. We had an Apple store with one and people loved to play with it for a few minutes but at its price point no one made a connection with it. Not even people we knew to be independently wealthy and collected 'toys'.

Lisa had an early capacitance keyboard sensitive to EMF. Our building was next to an AM radio station transmitter and talking or music resulted in a steam of ghost characters when you held your hand over it. For demoing the machine I had a ground wire running to an elbow rest and chair bottom. To type comfortably with no ghost I had to have a bare foot resting on the chair legs.

HocusLocus··on What is going on right now?
Difficult to see people anthropomorphize LLMs undeservedly, it's an extension of the childhood trauma inflicted by The Brave Little Toaster. Inanimate objects projected into personhood and subjected to a cruel and indifferent world.

Dangerous actually, the effect it had on children. Of course they loved it because it had a happy ending, but at what price?

HocusLocus··on What is going on right now?
LLMs are not 'ruining' em dashes. It's just a convenient device to unmask people who make critical judgements based on ridiculous and flimsy evidence.

It is good they are being unmasked. You must avoid those people and warn your children about them. They are not safe to be around.

Yes, and sulfur isn't the only cloud nucleation trigger. Refineries of ship 'bunker fuel' used to seek contracts from disposal companies to burn their chemical waste at sea. And dirty fuel has lots of natural vanadium. Source: oil spill around my houseboat legal case in the 1980s, fuel company had to disclose breakdown of content.
