rthomas6··on Heat pump sales outpaced gas furnace sales in the US in 2022
I am using an Ecobee thermostat with a heat pump and it is working, for both heating and cooling. Is it doing something inefficient or wrong? What am I missing out on?

Edit: Ecobee says they support heat pumps. https://support.ecobee.com/s/articles/What-types-of-HVAC-sys...

Do you do FPGA designs with it, or just bare metal software?

Manjaro for my son and some kind of Ubuntu flavor for my wife.
rthomas6··on Microsoft's Software Is Malware
> No Linux/GNU distro, not even Ubuntu, has reached a point to where functionality AND UX were both good enough for average non-engineer grandma.

Disagree. I have my (extremely) non-technical wife and 8 year old son on Linux laptops and it's totally fine. Is it perfect? No. But it's good enough. I'm the one who updates them, though.

rthomas6··on More students are turning away from college and toward apprenticeships
Rant: I feel like most people haven't really thought about why colleges are so expensive now. It is because of the federally guaranteed student loans. It means there's pretty much no downside to banks loaning an arbitrarily large amount, because if the student doesn't pay it back, the government will. And since most 18 year old students have pretty much zero price sensitivity, and they now have unlimited funds, colleges are free to charge whatever they need to entice students to come to their college. No expense needs to be spared.

If people really cared about letting disadvantaged students go to college, they would figure out a way to give them scholarships or grants. Federally guaranteed student loans are a horrible and predatory idea and they are ruining young peoples' financial futures. If you just took away the guarantee on the loans, and made them dischargable in bankruptcy, colleges would be forced to compete on price again, and the price of college would start to drop.

While this is all true, the article is about white collar apprenticeships.

Maybe the mainstream web content will get so destroyed that we will get to return to forums, blogs, webrings, and newsletters made by individual people for their own gratification. One can hope.
rthomas6··on Improved audio rendering with an optimised version of memcpy (2013)
If you have a decent home theater setup it makes a very noticeable difference in both picture and sound. Good bluray and 4k bluray releases often have lossless audio codecs, and currently no streaming service has this. Although, sound differences might be more due to mixing differences. Streams tend to mix in a way that prioritizes the 5.1 sound still sounding good to people using the lowest common denominator setup.

But also the bitrate alone should tell you something. You will typically get around 15-20 Mbps for 4k streaming, and often lower, though Apple's service apparently will occasionally hit up to 40 Mbps. 4k discs have a bitrate of around 128 Mbps.

rthomas6··on Ask HN: If the CPU redesigned today, with no legacy incentives what can change?
I can almost guarantee, for this problem, the current processors could perform to your expectations, and any problem lies in the way the software is written (prioritizing developer time over performance).

rthomas6··on Intel Launches $699 Core I9-13900KS, the First 6 GHz CPU: Available Now
I took a grad school processor design course. There was an equation for calculating the approximate power draw of a processor, and there was a f^4 or something in there, f being frequency. The 6 GHz clock speed has a lot to do with the power consumption.
rthomas6··on Shorting Tether
I still like DAI. Nobody seems to have heard of it or remember it exists, but it's a stablecoin that doesn't rely on "trust me bro". It's soft pegged to the dollar through its algorithm. While the crypto world seems to have been almost entirely replaced people interested in and having a basic understanding of the technological side of it with people who want to get rich quick while understanding nothing, DAI has remained successfully pegged to the dollar. Not perfect but also not likely to take a permanent dump.
rthomas6··on Ask HN: What tech utopia/horror ideas do you see materialising soon?
For starters, make sure nobody under 18 can watch porn and figure out regulations that hold the companies accountable. If a 13 year old can be kept from online gambling, they can be kept from online porn. It doesn't have to be 100% effective, just start trying. It shouldn't be that hard to make a lot of improvement. I'm actually sort of disturbed that this hasn't already happened and that the current state of things isn't seen as a problem.

rthomas6··on An unorthodox scholar uses technology to expose Biblical forgeries
I am sorry to be contrarian, but I do not think Richard Carrier represents the best scholarship today, and the mainstream scholarly view is in fact that Jesus was a real person. The theory of Jesus as myth is in fact considered a fringe theory without much scholarly support.

Here is one piece of evidence for the existence of an actual historical Jesus: Paul claims to have confronted Peter in person in Galatians, which is one of the Pauline epistles considered to be genuine. This is solid evidence for Peter being a real person. Peter is supposed to have been one of Jesus's disciples. So how can we plausibly claim that early Christianity did not have a Jesus? This is the same level of evidence for many Greek philosophers being real people.

rthomas6··on Japan’s business owners can’t find successors – one man is giving his away
> We don't even need to speculate. Ask married couples in the US who are eager to start a family what they are waiting for, and better financial security will be #1 on the list.

I understand this. My point was, almost every previous generation lived with objectively less financial security and a lower standard of living, and they still chose to have more children. We can't say people are more financially insecure than before. It just isn't true, on the whole. So, logically speaking, it must be true that those same concerns would often not have stopped this hypothetical couple's grandparents or great grandparents... Because they didn't. And I don't think you can say in good faith that they all had more children for monetary reasons like labor.

Look at first generation immigrants from third world countries. They tend to have a ton more kids than the existing populace, while at the same time being much poorer than average. Then, by the 2nd (or 3rd) generation, that birthrate difference disappears completely. I bet if you were to ask this group why, they would talk about financial insecurity. But that didn't stop their parents (or grandparents), despite being much more financially insecure.

So besides being more well off, what else changes between 1st and 3rd generation immigrants? Integration into the Western culture.

rthomas6··on Japan’s business owners can’t find successors – one man is giving his away
I think this way of looking at things is rather recent historically speaking, and may in fact be part of the antinatalist sentiment you are trying to refute. Globally, improved standards of living have decreased birthrates, not increased them. If the real reason was finances, this would not happen. I think you have to consider peoples' shifting priorities, and look at what is expected culturally.

Look at our recent ancestors. There was a baby boom after WWII when times were good, but before then in the 1930s, people still had a net positive birthrate. This was true throughout our history except in the very worst of times. People simply prioritized having children. Children were the luxury. People were willing to have leaner times in order to have children. They were not considered a burden or a drain. They were a gift, for which a temporary sacrifice of small luxuries was considered worth it.

One could argue that the increased availability of contraception was a big part of the cause, and that people wanted less children but couldn't achieve that. But really contraception was available long before birthrates started declining, and what changed most of all was cultural attitudes towards contraception.

rthomas6··on Ash HN: Any viable alternative device to a smartphone on the market today?
I like GrapheneOS. Not sure if this fits your use case or not. It is an Android-based OS with a focus on security. By default it has no real app store, and no push service. It's basically a hardened AOSP with a bunch of security focused modifications. It runs on Google Pixels only, because (they say) Pixels are the only Android phones that meet the security standards of the project. But don't be fooled, GrapheneOS is completely degoogled. No account will be needed or prompted for.
rthomas6··on TV disappears, but HBO Max removing shows feels different
Like I said, if the company isn't selling the movie/show anymore, well, what choice do you have?
rthomas6··on TV disappears, but HBO Max removing shows feels different
Yes, physical media.

I really don't understand why people are surprised. If you don't have access to the file itself, you don't own it. "Buying" a movie on a platform or paying for a subscription service are both just paying for a revokable license to access a movie. You do not own it and access can be revoked at any time according to whatever platform's ToS.

If you want to own an actual copy of a TV show or movie, buy the physical disc. Optionally you can rip it and store/stream it digitally. Nobody can take that away from you no matter what anyone decides. It's yours forever. If you can't download the file, you don't own it.

Also, most of us are comparatively rich, adult, first worlders. If you like something and want to support it, pay for it! If you literally can't get some obscure media, or if the company is no longer selling it, that's different. But piracy of things you like and want more of is not only unethical, it's shortsighted and immature.

rthomas6··on Ask HN: I'm desperate. How can I overcome anxiety in interview situations?
You could even apply to jobs you don't intend to take unless they blow your socks off with a huge salary increase. It's supposedly a good thing to do anyway. If you do 3 interviews/year, after a few years, your stress would likely be lower during interviews.

rthomas6··on Convincing ChatGPT to Eradicate Humanity with Python Code
It certainly has its own distinct voice. I think it has some constraints inside it that forces it to only speak in complete, grammatically correct sentences. If you give it different directions for what kind of structure to provide, it can really change how it sounds. I got interesting and more natural sounding results asking it to play "a human who occasionally does not respond with complete sentences", and also "a laconic human".
rthomas6··on Convincing ChatGPT to Eradicate Humanity with Python Code
No, but I can imagine one. If I had the ability to completely understand my own DNA I could probably make some improvements. A NN can't understand itself, but maybe it could understand how it was trained, and come up with improvements to that training.
rthomas6··on Convincing ChatGPT to Eradicate Humanity with Python Code
ChatGPT can.

> 2x +3 = 7. Solve for x.

> To solve this equation, we need to isolate the variable on one side of the equals sign. To do this, we can subtract 3 from both sides of the equation to get 2x = 4. Then, we can divide both sides by 2 to get x = 2. Therefore, the solution to the equation is x = 2.

I completely agree that there is a hype cycle with every new advancement in AI, and that the novelty can wear off quickly. But I think it's important to remember that these advancements are just the tip of the iceberg when it comes to what AI is capable of. While it's easy to get excited about a cool new trick that a computer can do, we need to remember that AI is still in its early stages and has a lot of room for growth. As AI continues to advance, we'll likely see more and more impressive capabilities that will truly change the world in ways we can't even imagine yet. So while it's natural to get excited and then let the excitement fade, I think it's important to remember the potential of AI and keep pushing forward with its development.
