chiph··on Danish supermarket chain is setting up "Emergency Stores"
Most of the cost of currency is up-front in it's production and initial distribution. The cost of handling it is also mostly up front (purchasing a wallet to hold it, buying a cash register with a drawer for the bills and coins). The transactional costs are things like taking it to the bank for depositing. But if you have cash to deposit - your business is probably doing things right and this is negligible.
chiph··on Samsung taking market share from Apple in U.S. as foldable phones gain momentum
I think there are two factors that drive the purchase. Primarily - it's a status symbol. I am reminded of the scene with Paul Allen's business card...

But also that it's useful when you want a larger display surface in a more portable form. Like watching films on an airplane or reading documents without having to constantly swipe & zoom.

I agree with the other poster(s) that Apple is likely working on a folding model, even though it would sabotage sales of some iPad models.

chiph··on The World War Two bomber that cost more than the atomic bomb
Each turret had it's own analog computer. Here's an explanation by the curator at The Museum of Flight in Seattle.

The B-29 also had ECM detectors and transmitters, so they could block enemy radar signals.

chiph··on Comic Sans typeball designed to work with the IBM Selectric typewriters
One of the Teletypes I used to work on had an eccentric-driven Wiffletree to position the typebox. This was necessary because of it's high speed[0] to decode the ASCII character set (it wasn't a Baudot machine). The selector cam at the end of the machine would do the serial-to-parallel conversion, then clutches would rotate the eccentrics powering the wiffletree to select the character.

If you look at the ASCII chart [1] you can select a character via binary tree - the Wiffletree being a mechanical equivalent.

chiph··on States target wealthy homeowners with new property taxes, sparking backlash
Pushing up home prices (via comparable valuations) is the issue. Not affordable housing per-se.

These second homes cause a hotspot in local prices that then spreads out further over the years as the neighbors sell their homes and demand higher prices (since "that's the market now"). Eventually (a decade or more) it does affect cheaper homes in the area and price out people.

But knowing human nature, this is probably just local government doing a money grab. Because someone buying a $23mm home won't even miss the little bite.

chiph··on Notes on Managing ADHD
Getting diagnosed is the first step. It can be a steeper step for some than others. But once you have a medication that works for you (which sometimes takes a few attempts) then you'll find that task avoidance becomes less frequent. Having a to-do list will help you ensure that the "must-do" tasks get completed. I rely on my phone's calendar, task list, and a journaling app named Daylio that I use to track how effective I was in completing tasks that day (you pick an emoji)

I was fortunate to find a physician that specializes in ADHD. Most of his patients are children/teens but they also see adults like myself. You can also go the route of seeing a psychologist that specializes in ADHD.

chiph··on U.S. government takes 10% stake in Intel
Looks like they will get common shares (not preferred). Could Intel create a new share class for this investment (with different voting rights)? Does 10% give the government a controlling interest?
chiph··on Making Your Own Merchant Service Provider
It's commonly a low volume - high value transaction, so they can charge that much. I have used them to buy houses and change banks. But not to buy a car - because car dealers are evil and there's no way to easily reverse one when the dealer stiffs you.
chiph··on New treatment eliminates bladder cancer in 82% of patients
Pluvicto (brand-name in the US) wasn't appropriate for my treatment, but I'm glad you were at least able to get those few months together before he passed.
chiph··on Inside OS/2 (1987)
You're probably right. It was long long ago... I keep meaning to look at ArcaOS but I never seem to have the hardware to dedicate to it at the same time my interest returns.
chiph··on New treatment eliminates bladder cancer in 82% of patients
One of the things I learned going through my own treatment (prostate) was that everyone's cancer is different. Which makes sense if you think about the variability in malignant cell growth.

So something that cures half the patients and only requires an office or outpatient visit every few weeks (no surgery, no radiation) is astounding. This result will likely lead to further research using this approach.

chiph··on All known 49-year-old Apple-1 computers
The one in Austin (piano themed) met a sad end.

Part of their old space is now being redeveloped for a MicroCenter.

chiph··on A CT scanner reveals surprises inside the 386 processor's ceramic package
kens - Presumably they chose the pin assignments to make it easier to arrange traces on the motherboard side. Or did they?
chiph··on Inside OS/2 (1987)
Because of that, I got good at creating multi-threaded GUI apps. Stardock were champs at this - they had a newsgroup reader/downloader named PMINews that took full advantage of multithreading.

The rule of thumb I had heard and followed was that if something could take longer than 500ms you should get off the UI thread and do it in a separate thread. You'd disable any UI controls until it was done.

chiph··on It's Beginning to Smell a Lot Like Stagflation
The inflation part is guaranteed. Not sure about the "stag" part, but it could be coming - a friend works at a company whose product is used in many other industries (it's a critical part of their production lines), and their orders are down. This might be because of the death of manufacturing in the US, but might also be because their orders are also down.

For those who haven't heard the term before:

chiph··on Microsoft is open sourcing Windows 11's UI framework
What I miss about UI development on Windows is the commitment to help me create applications that seamless blend in, and look like something that Microsoft themselves had created. The introduction of web technologies has allowed the visual language of the Windows experience to fragment. Not just because Microsoft hasn't kept older applications up to date (like the Control Panel), but also because the modern tooling isn't providing the libraries to match their style.

From memory, this first started during Vista, where 3rd party devs just weren't able to match the translucency of the new Aero UI. And the lack of articles being published by the MSDN group with titles like "Here's how you add this new feature to your app" with examples in C, C# and Visual Basic.

chiph··on How Hyper built a 1M-accurate indoor GPS
Many times these stores have floor cleaning machines - either robotic or driven by a human. An employee could zip-tie their sensor to it, let it do its cleaning trip around the store, and return to collect the data later.

This would allow an employee to do several stores in a town in a single day. And potentially less chance of a workers-compensation claim being filed if they fall down while walking around looking at their device.

chiph··on Air Force unit suspends use of Sig Sauer pistol after shooting death of airman
It depends on your job in the USAF. I was a security augmentee[0] and we did not chamber a round. But the Airman who died likely protected missile silos, which are "no-lone zones" and they would be carrying with a round in the chamber.

https://en.wikipedia.org/wiki/Two-person_rule

The P320 is known to have accidental discharges for civilian owners (honestly - don't buy one). But Sig Sauer has stated that the M18 military version did not have those problems. We will need to wait on the results of the investigation to find out.

[0] An extra duty typically assigned to junior enlisted - we only armed up during exercises. Which brings back a story - we were waiting on the trucks to take us to our posts, and the room was full of Airmen armed with M16s and M60 machine guns. And we were all watching Justin Wilson cooking up some delicious Cajun food on the TV.

chiph··on A look at IBM's short-lived "butterfly" ThinkPad 701 of 1995
IBM used to have an outlet store at a mall near the Raleigh Durham airport (prior to the sale of the PC division to Lenovo), and they had some for sale. I was sorely tempted but even at the time it was underpowered. Such a cool design though.
chiph··on My Family and the Flood
This might be a good project for someone - take the terrain contours and rainfall location & amount into account when determining where to send alerts.
chiph··on My Family and the Flood
I think it has become a "term of art" used by agencies like FEMA and insurance companies. And it makes for a good soundbite on the news.
chiph··on My Family and the Flood
The "Once in a hundred year" saying is misunderstood. It's actually 1% chance each year. So you roll your D100 every spring.

Whether that's an acceptable risk is up to you. Having lived in central Texas, it's a region known for it's flash floods, and you should take the warnings seriously. If there's heavy rainfall - you should be asking where all that water will go.

In this case, I hope that Texas looks into upgrading their alerting system so that people get word in time to leave the area. The news was saying the weather center added additional staff for the storm (five meteorologists) but if their forecasts can't get to where they're needed, that's not good enough.

chiph··on Impacts of Adding PV Solar System to Internal Combustion Engine Vehicles
I believe that solar panels were an option on the Maybach 62S, and they would run the ventilation fan while you were parked so you wouldn't return to a hot car after going to the store.

Like everyone else has said - there just isn't enough area on the top surfaces of a car to do any noticeable charging.

chiph··on The Robot Sculptors of Italy
I doubt that's because of the introduction of robots, but because of the high price of materials and labor limiting who can afford them.

"60 Minutes" published a similar story in 2024 and the chunk of Carrara marble needed to produce a large statue cost about $300,000. To carve a statue entirely by hand from it would be more than a year's labor, so add another $100k+ to that. If a robot can do the boring part of removing the waste, that makes sculptures more accessible. And could result in an increase in the number of sculptors in the world who are doing the finishing parts that add beauty to the stone.

Where I have a problem with the approach is the use of 3D scanners and robots to mass-produce copies of existing masterpieces. If everyone has an exact copy of "David" then the value of the original is diminished.

If 3D design tools are used to create original pieces of art, produced with the assistance of robots (and maybe some that were never technically possible before) that's interesting.

chiph··on Operational Apple-1 Computer for sale [video]
Honestly, even if I had the money, I'd be too afraid to use it. I'd get one of the replica boards.

Those electrolytic capacitors will eventually need replacing. At that point you have to ask yourself if the value will be diminished more by replacing them (with as close to a vintage cap as you can find) to keep it running, or by letting it become nonoperational.

chiph··on The Hidden Engineering of Liquid Dampers in Skyscrapers
I don't recall him mentioning how the viscosity of the fluid changes it's effectiveness, but I imagine it would. For reduced maintenance costs (prevent algae growth) they probably use mineral oil, not blue water.
chiph··on China Builds New Large Jet-Powered Ekranoplan
How well do they perform in open ocean, where you would encounter larger waves than somewhere like the land-locked Caspian Sea?
chiph··on Dr. Demento Announces Retirement After 55-Year Radio Career
Late 1970's for me. I set a timer on Sunday nights to record it and would listen to it after school on Mondays.

It's where I first heard gems like the Star Trek spoof by Bobby Pickett. "Plot complication showing up on ship's sensors now, Captain. Switching to visual."

chiph··on Inside the Apollo “8-Ball” FDAI (Flight Director / Attitude Indicator)
I think it's "generally" true. I saw a mention of some where the transistor had 4 pins: Emitter, collector, base, and ground (can). Presumably for RF shielding and they wanted a higher quality connection to the can without soldering/clamping it directly.
chiph··on Inside the Apollo “8-Ball” FDAI (Flight Director / Attitude Indicator)
kens - Are the collectors of the output transistors on the amplifier boards connected to the metal can? I can see from the photo that the heatsinks don't touch (there's a gap between them for the capacitors). Did they use nylon screws to prevent an electrical path through the frame?
