I replaced an old condenser and furnace with a 21 seer 5 head mini split system last summer. It’s much quieter and allows everyone to have their preferred temp. My biggest surprise was the efficiency. I have amp meters on my mains, and I thought something was wrong when we first turned it on. The old condenser was 32k btu and the new one was ~40k, but it consumes 30% the energy compared to the old unit on average. This is all for AC. As for heating, my electricity bill is higher as I replaced natural gas… but I have solar. Anyways, heat pumps are pretty awesome IMO. On a new build I’d look at geo thermal heat pumps. Still a lot of theoretical efficiency to gain with improvements.
You can use a text editor. I’d look at the hello world Java application to see how simple it can be. It’s the frameworks that are responsible for config files, generated code, etc. That said, it’s much easier to manage large applications with an IDE.
PoS hasn’t had much impact. The leveling out there is more like related to fewer transactions. Proto dank sharding, which may ship in 2023, should have a bigger impact on gas fees.
Earnings are a fundamental factor. Forward earnings as well. In the last bull run, market caps skyrocketed way beyond sensible forward P/E because rates were 0% and growth equities were worth the risk. Now that rates are going up, the risk profile has changed. In the last year growth stocks that have not shifted to value stocks have been slaughtered. Think meta, snap, etc. At the end of the day there are way more factors than earnings influencing price. The options market even has a big impact on underlying assets. Anyways the risk profile has changed and value will become a stronger factor.
Cool. My takeaway is this: Instead of sending an RPC call to the network to execute code and change state, code is executed off chain (locally), and the state change is sent to the network with proof that it's valid state. If my thinking is correct, this is pretty awesome. The article was very well written IMO.
It does require more memory for tracking objects as well as storing objects longer than they are strictly necessary. So I would argue that manual memory management is most useful when there are memory constraints. But yes, GCd systems can yield more throughput. They are also easier to work with IMO.
It's unfortunate we have to consider the downside. That said, using Siri for common tasks saves time. It might only be 10 to 30 seconds here and there, but add that up over a day, a week, a year... and then multiply by millions of people... The time savings is massive. I expect the capabilities to grow, and adoption to grow, because it's more convenient.
I would say the NFT market places make it easy to buy/sell (liquid). Since contracts are composable it could be sold to a contract with distribution properties so there can be fractional ownership. Programmable money flows.
Just like baseball cards. That said, there are some interesting use cases where the NFT is paired with off-chain cash flow. See royal.io, where IP rights for music are represented by NFTs and the owner of the NFT receives royalties. I think having a liquid market for that kind of investment is more tractable than a jpeg without real IP rights.
Even ignoring the concept of adversaries, wireless mesh is difficult to scale. Throughput and range are inversely proportional. Environmental conditions can attenuate signal. Propagation of routes is tricky as the network grows. It makes sense for something like starlink where there is LOS and ownership. But for modern day bandwidth requirements wireless mesh doesn’t make sense. Useful for smaller deployments where the data payloads are small and the max hops is limited.
Intel fab blocking AMD may impact AMD but it will impact Intel’s margins. I really hope Intel gets back on track with EUV, but 10nm was a major blunder and setback. TSM has the leading edge monopoly right now. There is a chance it stays that way beyond 2023.
FWIW: I want competition for the sake of progress, but I am bullish AMD for the next few years, and may be bullish Intel once they demonstrate their ability to shrink their process and execute IDM 2. Then they compete with AMD again… and TSM.
If integration of RNA into the DNA integration is expected with viral infections, then shouldn't we expect that with vaccines as well? This isn't coming from a place of fear or rejecting the value of vaccines, I'm just curious.
I agree they are undervalued. That said, AMD is growing quickly in terms of earnings, and intel is not. I think it’s a matter of time and impeccable execution before Intel is winning again.
One summer in college I worked with my Dad as a timber faller. I had the luxury of getting paid for writing software before that (being paid to learn). On one hand I enjoyed the work… I was outside, getting great exercise, and I gained a ton of respect for my father. But by the end of the summer, it became pretty repetitive, extremely hot, and I was physically exhausted every day. Nearly 20 years later, when I feel like I am burning out for whatever reason, I reflect on that one summer and ground myself a bit. I have it really good. I’m extremely fortunate to have found interest in this world at a young age, and even more lucky to have hard working parents that supported my interest.
