You missed the lawsuits by everyone else.

You still need to build the power infrastructure to the rural areas. Build the infrastructure for the people, like roads, sewage, water, buildings, etc. Navigate the regulation and permit processes.

Space DC make sense when local governments and communities don't want DC built on Earth. Space DC is an engineering and finance problem, not a problem in legal/permission, real estate, power generation, grid delivery, environmental, etc.

For small arrays that can fit in L1 cache, it's ok to do more loops. For bigger arrays, cache miss could remove all the gains.

When I bought my car, it had no Car Play or Android Auto. Upon some investigation I found out that both of them were installed on all the current models. It’s just disabled on the cars sold without the option. Some open source software for the car entertainment system flashed on the car was able to turn on the flags to enable various features including Car Play and Android Auto. So a happy story.

One use of focused RF detectors is locating hidden cameras via scanning their WiFi or Bluetooth RF signals.

I have a heat pump based water heater installed in the garage. One side benefit is the garage got cooled down. It used to be that the garage got very hot during hot days. Now it’s cool.

What does it take to add support for a router? Support for tp-link ax5400 seems missing for a long time.

How's Alpine? Most of the containers seem to pick Alpine as the basis OS.

It's straight corruption, no matter of big or small business. It should have been randomized blind selection of business who have existed for more than a year, and the granted money pays for new employees' taxes. Blind selection takes out the path to corruption (not who you know to get the fund). Randomized to be fair. Government is bad at picking winners or losers anyway. Business more than a year to screen out frauds. Granted money for new employees' taxes to encourage hiring new employees. Paying the taxes only so that the money can be spread out to more people.

This is an interesting read.

You can solve the same problem with Range Min Query Tree. The query for balanced or unbalanced parentheses is O(log N). A two or three level RMQTree can represent billions of parentheses already (a two-level tree of 65536 branch factor = 4B parentheses). The query is O(65536 + 65536) or effectively O(1). For a four-level tree of 256 branch factor, the query is O(256 + 256 + 256 + 256) or O(1). It becomes a problem of memory access on the number of levels vs the number of entries to process per level. A total = 0 and min > 0 mean the parentheses are balanced.

The parentheses can be broken up into multiple segments, and be processed in parallel. Multiple RMQTrees can be used, one per segment, and the trees can be processed in parallel. Need to have a final pass to sum up the 'total' and 'min' from all the RMQTrees. Parallel processing probably doesn't gain much.

I think he didn't know cellular well enough and thought a wireless phone was unlocatable because it was mobile and not tied down to a landline. As a physicist, Shimomura would have known all about radio and signal. He just used old WW2 tech of radio triangulation to find the location of the cell phone radio transmitter. It didn't help that cell phones were rare back then and the signal of his cell transmitter frequency was standing out like a sore thumb.

Regarding the full weight of the police, Shimomura did have an easier time to convince the ISP and phone companies to give him access to the logs. He was able to ask the cellular company to locate the cell tower where Mitnick's cell phone connected and traced him to the general area. If Mitnick had been careful, he could have hacked into the ISP/phone companies and erased all his access logs.

Oddly, since the Covid time, I haven't caught a cold or flu once. I'm not sure it's the vaccines, the flu shots, or the less physical contacts on things overall. I still go to crowded places from time to time, like plane or train rides. May be the population in general have less cold or flu virus overall to go around.

I read the book by Tsutomu Shimomura, who caught Mitnick's hacking and tracked him down. It's a fascinating read. He was able to locate Mitnick in physical world based on his online activities and his cellular phone usage. In those early days, few people understood the cyber landscape and cellular technologies to exploit them.

That's because they've reclassified unemployment status. Anyone working 1 hour out of N months is not considered unemployed.

"Is anyone still using emacs?"

Of course. Emacs has been my stable editor over many years, handling many languages that came along, surviving many other IDEs that came and gone (the latest being the Cursor sold out).

There're always new enhancements in Emacs, from multiple-cursor editing years ago, to LSP and tree sitter in recent years. Currently I just got into the vertico/marginalia/consult/embark combo packages. Embark with its context based actions seriously is an amazing underrated package.

Up to 40% unemployment or very low employment.

Plus electricity, labor, and maintenance?

The California state budget for 2026-27 is at $248 billions. Life is good for the state politicians.

Facial and gait recognition tech make the pedestrian vs car point moot.

VAT is a regressive tax. It hits everyone along the way, rich or poor. It hits the poor especially hard proportionally.

LoRa is for long range lower power communication. It can achieve a range of approximately 10 kilometers (6.2 miles) in practical conditions and up to 330 kilometers (210 miles) in perfect conditions. There are plenty of applications for it.

This is great. Other things needed for a great C development environment are a standardized build process plus build tools and a standardized packaging system.

I actually find music with lyrics helps me concentrate, as long as it’s an old song that I’m familiar. New songs are distracting as I would wander off trying to understand what’s being sung. Old songs have no such problem and they just become familiar background patterns.

Same here. Emacs has been the stable editor for all kinds of language changes, tool changes, and IDE changes. Emacs is great with LLM, as LLM is mostly text related and Emacs is great in capturing and dealing with text.

Yes. Many people set a limit on the maximum payout as doubling goes up very fast. A 8-fan win is $1280 payout, from each player. People usually limit the max to be 9 fan.

Base point is like the minimum payout. All players agree upon a minimum payout (base point) ahead of time. E.g. $10 as the minimum for the first fan. A fan literally means doubling. A 4 fan win means the payout is $10x2x2x2=$80 from each losing party. It can go up very quickly.

Looking from Earth at the stars closer to the center of a galaxy, they are found to be older. Looking from Earth at the stars closer to the edge of a galaxy, they are found to be younger.

I feel there should be a PowerToy applet to turn Segment Heap on or off.

Gen X was the last free range children. They ran wild after school without the tethering cell phones, playing in sand and drinking from garden hoses. The silent generation turned out to be a great generation building most of modern technologies.
