brianaker··on Norway Eyes Partial Ban of Smart Glasses
Only if they are used by janitors.
brianaker··on LG denies TV spying claims, says tracking and snooping concerns 'not true'
Create an open Xfinity Wi-Fi network, as well as an AT&T one. See if the TV connects to them.

This is probably obvious to most people, but I will mention just the same: do not install the antenna that the TV comes with.

brianaker··on Hitachi launches CO2 heat pump water heaters with solar-friendly tariff controls
A propane generator will not buy you much time or output.

If the home owner has natural gas? They should could get a natural gas generator, that way they have a continuous supply of fuel if the grid fails.

Grid and gas failure? That happens only after a significant event, like a major earthquake. Not much you can do about those sorts of events. ( The person lives in Ohio… so not as much concern. )

Cost-wise? They would be better with a dual fuel system for heating. They live in Ohio, they probably have AC so moving to dual fuel when the AC system needs to be replaced is the smarter option.

brianaker··on Hitachi launches CO2 heat pump water heaters with solar-friendly tariff controls
While in the US making a bathroom a "wet room" is rare, it can be quite common in other countries.

You can totally remodel bathrooms to be "wet rooms" in the US, it is well worth it.

Kids flooding the bathroom via the tub? Not a problem. Toilet overflowing? Gross, but not a problem.

I wish I would have made all the bathrooms in my home wet rooms.

brianaker··on Amazon Is Creating the Biggest Pollution Source in the Country
Trees are wonderful for a number of reasons, and the need for them for local climate, which includes shading and their contribution to local humidity, is important as well.

They are not, though, a significant sequestration for CO₂.

A helpful way to think about this is to consider coal. To produce coal the energy input comes from time, pressure, etc over tens to thousands of millions of years.

The significance of trees is for the local climate, or global if you are considering one of handful of rainforests.

brianaker··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
The funny part is that people think that Zigbee and Matter are open :)

All three of them have their shortcomings. Matter requires an unsecured IPv6 network to operate; I have my doubts about it having any longterm future.

brianaker··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
A mixture of threads and processes that can be used to match processors, disk I/O, and network interfaces.

A very long time ago, there was once a feature called "Data Blades" which tanked a commercial database vendor. A badly behaving blade could bring down the entire database. Most anyone who has been working on databases for a few decades remembers this and makes a point of either not introducing these sorts of features or making use of processes over threads.

I have not looked at the code referenced in the mentioned project, but thus far I haven't seen a model that could craft a complete SQL parser on its own.

There are a number of problems, and design decisions, that a developer decides on when writing a database that I don't see any current models… just because you have the ingredients does not mean that the stew is edible.

brianaker··on Fully Featured Audio DSP Firmware for the Raspberry Pi Pico
Why not use a crossover driver?

The loudspeaker would have used one; a driver is both cheaper and of higher quality.

brianaker··on Ask HN: Distributed data centers in our basements
If you don't need to manage cooling?

Then you are likely needing to manage humidity.

brianaker··on It's 2026, Just Use Postgres
It does have its use cases :)
brianaker··on In a milestone for Manhattan, a pair of coyotes has made Central Park their home
"I’ve noticed that we just don’t have outdoor cats in our neighborhood"

Stop neutering cats, encourage alley cats.

brianaker··on The $25k car is going extinct?
You obviously have not been following Subaru, while what you are saying was once true, it has not been true for several years now.

Google "Subaru battery", read about all of the additional electrical problems that are the result of Subaru being unwilling to fix a problem that is the end result of them selling your data.

Subaru stopped making reliable cars somewhere around 2014.

brianaker··on Turn any bicycle electric
US Law, i.e. Federal Law, for e-bikes is 15 U.S.C. 2085(b) and additionally Title 28 Chapter I Part 36 Subpart A § 36.105.

Pedaled vs throttle is an ablest issues; not everyone has picked up on this.

brianaker··on Do you need Redis? PostgreSQL does queuing, locking, and pub/sub (2021)
MySQL never had a problem with scaling to multi-core systems; Linux on the other hand did have a problem and its problems became everyone's problems. In the early 2000's the answer to multi-core Linux issues was to buy a system running one of the commercial UNIX. By 2006 or so this became a non-issue for Linux ( for the most part ).

Postgres uses an old design model which predates threads; I have no idea if they have made any progress in updating their design. In the past I have heard the core devs talk about how difficult it would be to do this.

Oracle Database moved to a hybrid process/thread model at some point, this is the superior solution ( I have no idea if it was done well or not, but from standpoint of how to achieve better leverage of CPU vs IO, this is the way ).

If the PG devs had enough time/money, I am sure they would move towards a hybrid model where the focus would be on processor affinity with IO being all tied to events.

brianaker··on Greenwich schools to ban most cellphones, Apple Watches, Fitbits and more
A number of years ago when my daughter was in the second grade the school expected them to turn in homework via this crappy power point knock-off app that would constantly crash.

I had her eventually just take screen shots and send them to the printer. From there? She would fill in her answers, take a picture of the work, and then drop the image into the power point knockoff.

We got a note from the Principal about how "printing" was not supported.

Whatever.

brianaker··on Supreme Court rules ex-presidents have immunity for official acts
Trump's attorneys did not say "the special counsel that prosecuted him was not properly appointed by an act of Congress", Justice Thomas brought this up in oral arguments. Trump's attorneys admitted in oral arguments that they had not brought this up during the appeal, so as an argument it was not saved.

Further more, historically there is no basis for the argument. Special prosecutors, which are different from the "independent counsel" that came about after Nixon; the laws around "independent counsel" expired a while ago.

"Special counsel", and all of the other similarly named, have been around since Marbury. By happenstance, some have been X-members of Congress, Cabinet members, etc... but far from all.

There is a reason why none of the other Justices brought this up, it is absurdist.

brianaker··on Zuckerberg personally ok'ed wiretapping both Amazon and YouTube [pdf]
How would Meta/Facebook accomplished this without reading Amazon's communication with its customers?

You have at least two parties in any conversation, I don't see where Youtube or Amazon consented, nevertheless, the recording was being done by Meta/Facebook, which was a third-party to the communication.

There are both Federal and State laws against the sort of wire-tapping that Facebook/Meta performed.

brianaker··on Zuckerberg personally ok'ed wiretapping both Amazon and YouTube [pdf]
Running a VPN service would not be wiretapping, but that is not what they were doing, and understand they had multiple avenues that they explored.

If you want to focus on just the VPN bit though; running a VPN would not break Amazon's secure communication. For Facebook/Meta to accomplish what they did they had to place fake endpoints in-between Amazon and its customers where they could pretend to be the party Amazon thought it was communicating with.

brianaker··on Zuckerberg personally ok'ed wiretapping both Amazon and YouTube [pdf]
That story links to a different document filed with the courts.

Additionally, the scope is wider than just what Onavo did for Facebook.

There are comments being made in that post as well where people are assuming all of the communication on one side, which was not the case at all.

brianaker··on Facebook: We install a root CA on the device and MitM all SSL traffic
What I find really surprising is that Amazon has not sought criminal prosecution of Meta.

Even if in all cases a user selected to allow Facebook/Meta to see what they were communicating, which from reading all of the attached documents I don't believe was the case, I don't see how Amazon gave consent.

If some individual had done what Facebook/Meta did, I can't see a situation where Amazon wouldn't have asked for criminal prosecution.

Mastercard and Visa? It would be surprising to see how they would just shrug this off; maybe this hasn't hit their radar yet.

Has Subaru been doing this as well with their STARLINK?
brianaker··on :syntax off (2016)
With vim you can restrict syntax highlighting by scope and/or folding, limelight.vim provides a good example how to implement this.
brianaker··on U.S. reenters the nuclear fuel game
Privileged myopia is certainly is alive in thriving!

I say this as someone who bikes their kid around most of the time; I love biking but it is way of life that only a minority of people can make work.

brianaker··on Chamberlain blocks smart garage door opener from working with smart homes
The description on the OpenThings website is misleading, the add-on module is an off the shelf commerical remote that is being shorted in order to operate the door.

The ratgdo device is decoding the line version of the Security+ 2.0 protocol, which gives you state information/etc. They have a page describing what they currently decode:

https://paulwieland.github.io/ratgdo/01_features.html

FWIW The Flipper Zero can decode the wireless version of the Security+ 2.0 protocol.

brianaker··on Sam Bankman-Fried Convicted
You are describing the plot to Robert Heinlein's short story "Coventry".
brianaker··on Rotary Woofer (2006)
The film "War of the Worlds(2005)" has effects going down to 20 Hz; to play it you will need an ATMOS AV receiver that has an LFE port to feed the signal to an amp that has LFE input. Not all amps which have an LFE input can cleanly output 20 Hz, let alone anything lower, so you would need to check the specs.

I wouldn't be surprised to discover that the original "Iron Man" movie reproduced effects at that level, but I know the "War of the Worlds" film does.

brianaker··on The Philips Hue ecosystem is collapsing
There are no announcements by Hue to developers that the CLIP API is going away, so I suspect there is a lot over speculation based on a clueless Twitter post made by some droid that most likely doesn't even understand the questions they were asked.
brianaker··on The Philips Hue ecosystem is collapsing
Just stop for a moment and ask yourself "could the author of this post be wrong."

Philips just introduced Matter support which requires local access, and continues to support Apple Home as well. There are dozens of apps which can manage their hubs. ( FWIW I use iConnectHue. )

Philips also just introduced cameras, which did require them to update their EULA.

brianaker··on Apple finally put USB-C in new iPhone, but limited to 23-year-old USB 2.0 speeds
Passive Thunderbolt Cables run at speeds of 40Gbp at 0.8m, otherwise they run at half the speed.

Active Thunderbolt Cables run at speeds of 40Gbp at 1.8m/3m.

All of Apple's Thunderbolt 4 cables are 40Gbp, the same cannot be said about all of the cables you buy from Amazon.

If you feel the need to blame someone? I guess you can blame Intel for the design.

brianaker··on Phenylephrine for colds and allergies don’t work, FDA panel says
The better you feel, the more likely you are to get better sleep.

Good, restive, sleep helps your body heal from most anything while the reverse, a lack of sleep, will always wreck your health.

There is zero nobility, or reason, for people to suffer through a cold.
