axiolite··on Comparing the power consumption of a 30 year old refrigerator to a new one
> Some also add incredibly annoying high pitch whines. That seemingly nobody seems to notice but me.

That drove me crazy for about a week trying to figure out what the noise was coming from... Pinhole water pipe leak? Cat stuck in the flue? Once I realized what it was, I didn't mind it much. It is better than loud old compressors suddenly kicking on and burrr'ing away then stopping.

axiolite··on Comparing the power consumption of a 30 year old refrigerator to a new one
I've found cheap after-market thermostats to have short lifetimes... Original lasted 20 years... Replacement started misbehaving in just 2 years.

So now my policy is to retrofit all old refrigerators with digital STC-1000 thermostats. A bit more work to cut out some plastic, split the hot wire and tap into a neutral wire (easy enough to follow the bulb) but cheaper, super reliable, and gives very consistent and highly controllable results.

Two such upgraded refrigerators are still working without an issue several years later. Though both required replacing the relay (with a solid state relay/capacitor unit) at about the same time, and one after replacement of the evaporator fan motor due to noise issues.

axiolite··on Are hard drives getting better?
PaperBack claims 0.5MB per page: https://news.ycombinator.com/item?id=39883531

It's likely not possible to do much better. I never said that was the most practical method.

axiolite··on Are hard drives getting better?
You can't get a perfect digital copy of a printed out photo. You're subjecting yourself to generational losses for no good reason.

If you're a fan of paper, you could base64 encode the digital photo and print that out onto paper with a small font, or store the digital data in several QR codes. You can include a small preview too. But a couple hard drives or microSD cards will hold many millions of times as many photos in less physical space.

axiolite··on AV2 video codec delivers 30% lower bitrate than AV1, final spec due in late 2025
Though things are pretty boring and stable right now, there have been many times when audio codecs were changing rapidly and many people didn't have (and often couldn't get or use) an audio codec that was being commonly used in video files distributed online.

You could technically fit 10 SD channels together in the US, except I recall that the government ("FCC") specifically REQUIRED (at least during initial rollout) at least one to be in highdef, unless you applied for a special waiver.

These days the FCC is unlikely to care, but I suspect viewership would suffer if any of the major broadcast networks downgraded their "main channel" signal to SD.

This explains the typical arrangement, as well as listing some of the extreme cases:

axiolite··on AV2 video codec delivers 30% lower bitrate than AV1, final spec due in late 2025
Circa 2009 when analog TV was first shut-off in the US, each DTV station usually only had one channel, or perhaps a second basic one like a static weather radar on-screen. Some did have 3 or 4 sub-channels early on, but it was uncommon.

Circa 2019, after the FCC "repack" / "incentive auction" (to free-up TV channels for cellular LTE use) it became very common for each RF channel to carry 4+ channels. But to be fair, many broadcasters did purchase new, improved MPEG-2 encoders at that time, which do perform better with a lower bit-rate, so quality didn't degrade by a lot.

"A terrestrial (over-the-air) transmission carries 19.39 megabits of data per second (a fluctuating bandwidth of about 18.3 Mbit/s left after overhead such as error correction, program guide, closed captioning, etc.),"

> FPGAs' in our machines that you could just use flash to the newest codec

They're called GPUs... They're ASICs rather than FPGAs, but it's easy to update the driver software to handle new video codecs. The difficulty is motivating GPU manufacturers to do so... They'd rather sell you a new one with newer codec support as a feature.

Why? ATSC is 19Mbps. A single 1080i video using that whole bitrate will look quite good.

> You especially notice the compression on gradients and in dark movie scenes.

That can happen at even the highest bitrates if "HDR" is not enabled in the video codec.

axiolite··on Using a laptop as an HDMI monitor for an SBC
> I always thought it would be great to have a "laptop without a motherboard"

That's basically what a rack console is. At 1U it was skinnier than laptops from prior decades. They're not exactly a laptop form factor, but to get them smaller you would have had to accept a much lower screen resolution, which would risk some systems not being able to display (e.g. your server may have booted-up to 1280x1024 while your laptop could only do 800x600), or would have needed to be quite expensive to add an ultra-high DPI screen.

Still, at various times there were briefly devices like that available for purchase at closeout prices... like the failed "Motorola ATRIX lapdock":

I'd say the USB-HDMI capture card is a better solution all-around. I even prefer it to USB "crash carts" because you aren't dependent on the manufacturer keeping their proprietary software software updated for each subsequent Windows/Linux/Mac release.

axiolite··on Using a laptop as an HDMI monitor for an SBC
> A niche thing, but it shouldn't be expensive to implement, and the ports are already here (usb-c, hdmi).

A Display Controller Board for driving a laptop screen from an external input is going to add at least $20 to the price of the laptop. Considerably more expensive than the $6 USB-HDMI capture devices which do the job (and have more utility).

The HDMI output port on your laptop (if you even have one, many only offer miniDP) can't just be run in reverse. The board would need to be updated to allow switching it between output and input, at considerable extra cost.

axiolite··on Bob Ross paintings to be auctioned to fund US public broadcasting
> Thinking they will suddenly come to their senses is just delusional.

Abstract proclamations don't affect people. Taking something away from them, affects them. That's when the rubber hits the road. That's when the public starts turning on the politicians. Even the strictest party-line voters don't support EVERYTHING (or even most of what) the party says and does.

> They don't let their kids watch educational shows.

> They have an entire "alternative" media infrastructure set up.

"PBS has also reported a diverse ideological split among its consumers [...] 26% who self-identify as Republicans and 37% who say they are independents."

https://www.thewrap.com/defund-pbs-npr-impact/

"Among those that voted for President Trump, PBS/public television has a much higher positive image rating (60%) than the traditional broadcast networks (37%), cable TV networks (41%) and newspapers (24%)."

"66% who voted for President Trump favor increasing or maintaining federal funding for public TV"

Wouldn't it be better to let those towers go dark, and await the public outcry, instead of temporarily hiding the effects?

The PBS affiliate stations in most need of federal funding are typically in rural, largely Republican areas. Let their own base tell the party they're not happy about being cut-off from their baseball documentaries and all the educational shows their kids watch.

axiolite··on Inkjet printer with DRM-free ink will be launched via a crowdfunding campaign
Epson Workforce Pro WF-7820 is just $200 on Amazon right now. Brother MFC-J5340DW is currently at $280.

Tabloid printing used to be quite inexpensive... Any 11" wide dot-matrix printer could manage it.

The rise of inkjets made it relatively more expensive. I resorted to rescaling tabloid (11x14") printouts to US Legal (8.5x14") to keep old business applications working.

In recent years, as A3 format copiers (with network printing) have become very common in offices everywhere, it's becoming inexpensive to print on tabloid sized paper once again.

axiolite··on Athlon 64: How AMD turned the tables on Intel
> Alpha systems were very expensive, and so they had a limited customer base.

That's the usual chicken & egg problem... If they sold more units, the prices would have come down. But people weren't buying many, because the prices were high.

Itanium, like Alpha, or any other alternative architecture, would also have trouble and get stuck in that circle. x86-64, being a very inexpensive add-on to x86, managed to avoid that.

axiolite··on SSH3: Faster and rich secure shell using HTTP/3
Telnet, FTP and rlogin wasn't broke, either. They had their own encrypted variants before SSH came along.

Listing all the deficiencies of something, and putting together a thing that fixes all of them, is the kind of "designed by committee" project that everyone hates. Real progress requires someone to put together a quick project, with new features they think are useful, and letting the public decide if it is useful or not.

axiolite··on US cities pay too much for buses
> 2. If getting through downtown by bus is slow, getting through it by car isn't any faster.

If the buses and cars are on the same roads, going the same speed, the car will get you to your destination faster, and everyone will go by car. Buses only get ridership if they have dedicated lanes where they can go faster than regular car traffic:

axiolite··on US cities pay too much for buses
It's not that pushing buses onto surface streets makes it worse for cars. It's that it makes it worse for buses, which then leads people to take cars instead, which makes things even worse.
axiolite··on Athlon 64: How AMD turned the tables on Intel
> if intel's compilers and architecture had been stellar and provided a x5 or x10 improvement it would have caught on.

That sounds like DEC Alpha to me, yet Alpha didn't take over the world. "Proprietary architecture" is a bad word, not something you want to base your future on. Without the Intel/AMD competition, x86 wouldn't have dominated for all these years.

axiolite··on Disney reinstates Jimmy Kimmel after backlash over capitulation to FCC
I clearly said: "as they secure alternative broadcast arrangements in each area"

TV broadcast tower agreements are not ossified. Every year some station switches from one to another. Comcast buying NBC led to quite a spate of that in several markets. It can be slightly disruptive on the fringes (like Comcast/NBC*) or it can go unnoticed or even improve reception.
