jhallenworld··on California closed the Montana license plate loophole
I've seen car dealers in MA use Montana dealer plates. At the very least they are cheaper, avoids $220 / year excise tax and registration fees vs. $25 for Montana. I don't think it helps with any sales taxes- dealers don't have to pay when they buy cars, unlike customers. It would help if dealer uses the car personal reasons instead of just having it for resale.

Hmm... maybe I should start a car dealer just to avoid taxes on my next car..

The Montana plate for owners reminds of registering your boat in Wilmington Delaware to avoid state sales tax. You had to create an LLC to do this I think.

jhallenworld··on cp: -r or -R?
I never bothered to learn -C, instead I use:

    tar -cf - . | (cd <dest>;  tar -xf -)
For doing something like duplicating root of a filesystem you may want --one-file-system.
jhallenworld··on On social reality in China
Ah, I think the origin of this video style is "Zaza in China"- or at least he's the most successful at it.

jhallenworld··on On social reality in China
Well I'm grouping these under AI- they have been around a while for sure, but maybe they have reached some kind of critical mass there: I'm imagining people on Chinese social media talking about it as a way to make money.

Also the text to speech is in their own voice. Some are using this as a way to help pronounce english (maybe there is some language training software available for this, I don't know).

jhallenworld··on On social reality in China
An interesting recent phenomena is that regular Chinese people have figured out how to use AI to speak for them to make english language youtube videos. They are quite fascinating to watch, because you don't normally get such an unfiltered perspective. I think people feel safe posting these because nobody knows them in the west, whereas family, friends and govt. see Chinese social media. And of course youtube is banned in China.. Some of them make a few hundred bucks from Alphabet, this is a big deal.

Here are a few (check out the comments- working class people from around the world make contact):

Anyway, I view this as one of the more positive uses for AI.

The Iranian revolution was due to messages spread on cassette tape. It's all Phillips's fault.

CB radio then.
jhallenworld··on Kids turned low-traffic NPR Spotify comments into a secret group chat
"The goal is just to connect with people. You have nothing to talk about. You don't know each other very well. You're just seeing each other and acknowledging each other's presence"

This right here is ham radio in a nutshell. These kids need transceivers and should give morse code a try.

jhallenworld··on Z80 REPL (2018)
You should support symbols... For example, the monitor on my 6800 / 6809 Exorciser simulator has this (the "Offset at..." is printed when it fixes forward references):

    ~/exorsim$ exor -d
    % a 1000
    1000: start bra skip
    1002:  nop
    1003:  nop
    1004: skip ldx #10
    Offset at 1001 set to 02
    1007: loop dex
    1008:  nop
    1009:  bne loop
    100b:  rts
    100c: 
    % sy
    1007 loop
    1004 skip
    1000 start
    % u 1000
    1000: 20 02               BRA $1004
    1002: 01                  NOP
    1003: 01                  NOP
    1004: CE 00 0A            LDX #$000A
    1007: 09                  DEX
    1008: 01                  NOP
    1009: 26 FC               BNE $1007
    100B: 39                  RTS
What would be even better: "a" brings up a built-in mini-editor. When you exit, the code is assembled.

jhallenworld··on What Sun got wrong
I seem to remember IBM had a way to buy their stuff online, but not anymore apparently. I'm sure this was back in the System x days.
jhallenworld··on Lotus Notes and the dangers of starting from scratch
I had to use Notes after our company was acquired by IBM in 2005. As a startup, we used Thunderbird. What I remember was that finding things in Thunderbird was just so much faster because it had a filter feature (you enter a string, then instantly only the messages with that string would be shown). No such feature in Notes- I remember having a hard time finding messages, and that its search feature would miss things somehow.

Yeah, Notes had its shared database features, and you could see remnants of IBMers using them at the time, but most such applications been ported to Java CRUD apps. Also Lotus Sametime (it's like Slack) became a much more important collaboration tool.

jhallenworld··on Altair Basic Interpreter Source Code (1975) [pdf]
I always thought that the floating point routines were the big feature that made Microsoft BASIC a thing (compared with both Radio Shack and Apple integer BASIC). It's interesting reading about Monte Davidoff and also that Gates knew they needed a specialist for this.

jhallenworld··on Refurbishing a Tektronix TDS7104 Oscilloscope
>an original 7104

I've got one, they are very cool. I also have a 7834 (storage tube), cool in a different way. On the other hand, they are taking up a lot of space... I also have two 485s, one with a broken trigger.

jhallenworld··on Refurbishing a Tektronix TDS7104 Oscilloscope
We've rented them in the past- always we're not quite sure we're done so keep them much longer than necessary. They're kind of a pain to pack and ship.
jhallenworld··on Refurbishing a Tektronix TDS7104 Oscilloscope
Yeah 1 GHz is nice, but that tiny 200 MHz Siglent is going to be much more useful in practice for most things.

Speaking of boat anchors, I'm trying to get my company to buy a DSA91304a (13 GHz scope with SERDES debugging). ~$44K with all the options, but still Windows-XP. The Windows-7 ones unfortunately don't have the options I want. Maybe there is a hack..

My goto has been Shotcut, it's main advantage is high resolution support without having to pay extra compared to something like Lightworks (which has a better UI for sure, but I'm not paying...).

jhallenworld··on Bubble Memory
I worked at a place that evaluated bubble memory, but didn't use it (they had the bubble memory dev. boards). But they did use CCD memory. I remember it was prone to bit errors, which would have been OK if there had been any error correction, but there was not.

jhallenworld··on Elevators
What this doesn't include: not all people are equal. Do you want the CEO of your new office building to have to wait behind a bunch of plebeians? At least one car is going to have to be reserved for the better people.
jhallenworld··on Why is everyone trying to build a solid-state battery?
I think "solid-state" is a marketing term which means you need to use Fermi-Dirac statistics to model your device, vs. vacuum tubes where you can use Maxwell-Boltzmann statistics. I think you can use Maxwell-Boltzmann at least for the ions in the electrolyte.. but maybe have to use for Fermi-Dirac for all conductors in a solid-state battery.
jhallenworld··on Superlogical
The server being their server that you eventually have to a pay a subscription to use? Hmm..

Also, interesting permission problems. Are you going to allow a remote server owned by someone else have shell access to all of your computers? Are they allowed to train an LLM from all the things you type?

jhallenworld··on LG to ban residential proxies from smart TV apps
So actually, this TV is for an AIR B&B I rent out. I guess technically I need to add their stupid EULA to my rental agreement.
jhallenworld··on LG to ban residential proxies from smart TV apps
The main point of selecting the country seems to be getting you to consent to the country specific EULA. There's also region-based content management, but it's secondary at this point.
jhallenworld··on LG to ban residential proxies from smart TV apps
I have a new LG TV, holy moly what a terrible user experience. Out of the box it requires you to create an LG account. PITA, but OK. Except I was supposed to set the location first, instead I set it after. So now you have the problem that you can not log into LG.com using my own email (even from a web browser) because it says: "incorrect country". I contacted their tech support about this, the only fix is to switch back the country code on the TV (to US_Other), then delete the account from there, then set country code to US, then create it again. OMG. I guess there is no fix if TV breaks before you do this..or if you forget what the original country code was. You are then forced to use a different email for any future LG product. I notice that all LG smart products use the same phone app, BTW.

Also, I bought an LG soundbar to go along with it. You would think they would work well together. The soundbar sounds fine, but the synchronization drifts over time. I've tried optical, LG's enhanced optical (allows you to control the volume) and HDMI eARC. In theory optical in PCM mode works better, but then you give up the volume control. Why should an end customer know about any of this? Lip sync is a simple problem to solve (timing pulses and code slipping will always work) and they have failed at it.

Also: their remote sucks (compared with Roku).

Anyway, so no respect for LG.

jhallenworld··on Every new car sold in the European Union must include a driver monitoring camera
>2008

I bought a 2017 Kia Forte S recently.. ($4000 for 137K miles) no touch screen, but many safety features that are not too bad like radar collision detection and blindspot warning. 2019 they started with the touchscreen, and in 2023 they added "Kia Connect" with OTA updates. Anyway definitely check the year.

Problem with 2008 is some cars didn't even have Bluetooth audio or backup camera yet (like my 2010 VW CC- I had to add an aftermarket radio).

Also don't get direct inject only engine. At least for Kias, the non-turbo engines are much more reliable (but underpowered for sure).

jhallenworld··on The redistribution of housing wealth caused by rent control (2023) [pdf]
When Boston ended rent control in the late 90s, all of the sudden the landlords invested in their goldmine buildings and generally improved the city. It sucks for those trying to rent or buy (including me, I paid 60% more for a house in 2002 than what it was worth in 1996), but the city has certainly had a renaissance.

IMHO, the problem now is bad zoning. The rich car-centric suburbs are preventing denser housing- to their own financial detriment. A recent fight is that the state has forced them to allow higher density housing around commuter rail stops. Similar fights about rail trails, future abutters are afraid of change but they are valuable everywhere they exist- in that they are a desirable feature and raise your house's value.

Another problem is that they overbuilt $100/sqft bio-lab space. These are sitting empty, and the owners refuse to lower the rent.. I don't understand how the owners remain solvent.

jhallenworld··on US Consumer Price Index up 4.2%
Suppose you want shelter. It used to be that you could buy a house for a reasonable price and move in. But now that's unaffordable, so instead your have to pay rent. In CPI thinking these are equivalent forms of shelter, but I bet if you asked most Americans, they would not agree with you.
jhallenworld··on US Consumer Price Index up 4.2%
No it's cooked. For high tech items, they assume that improved technology means you are getting more for your money even if the price goes up, so they discount it. It's true that you get more for your money, but it ignores threshold effects, like you just can't buy an equivalent phone for $10 even if todays phone's are 200x better.

Then there's the "owner's equivalent rent" BS and this is 25% of CPI. It answers the question "If someone were to rent your home today, how much do you think it would rent for monthly, unfurnished, and without utilities?" It assumes rental price and housing costs are somehow linked when in reality asset prices have far outstripped rent.
