jsharf··on Google Launches Carbon, an Experimental Replacement for C++
You don't need to rewrite existing code. Just develop new code in it.
jsharf··on The effects of sleep debt
Generally speaking, I'm a back and side sleeper, but sometimes if I really need to sleep, I always find stomach sleeping works the best (and lowers stress -- if something was keeping me up, stomach sleeping usually helps). That being said, it hurts my back to sleep on my stomach. I've found the putting a pillow under my stomach helps, but not completely.
jsharf··on GitHub Copilot is generally available
They still have to pay for servers and maintain the model itself. A neural network isn't just the data -- training and commercializing it (testing, QA, etc) is a lot of work.

You wouldn't have an issue with someone making money by using open source software (like a website that is hosted on a server running linux).

jsharf··on Seven Teslas have caught fire in the last four days
Another reason this might be news-worth is if the rate of Tesla fires suddenly rose. I didn't look at any numbers and I suspect the number didn't suddenly change. Just trying to point out that ICE fires aren't the only baseline to compare to.
jsharf··on IPCC’s starkest message yet: extreme steps needed to avert climate disaster
There's some misunderstanding probability going on here.

For example, if the population stays at 8B between now and infinity, and we assume a uniform distribution of % chance you're born at any time, then it's just as equally likely that you'd be born at the beginning as at the end. There's no higher chance that you'd be born in the middle, whatsoever.

Now actually the population is likely to grow, so if anything it's much more likely that you'd be born towards the end. That begins said, some people have to be born first and of course if they thought this way, they might say things like "oh what a coincidence, this is highly unlikely" or "It's far more likely due to exponential growth that any one person exist towards the end of humanity, so therefore this must be the end", but of course, this thought could have been had by cavemen 1000's of years ago and they'd be wrong.

jsharf··on Google Search Is Dying
Appending "reddit" to the beginning of search queries could get SEO'd away too if enough bots start posting to reddit :/
jsharf··on Show HN: An AI program to check videos for NSFW content
yeah but this is true for profanity filters as well, and yet useful profanity filters still exist. Is it 100% accurate? No. But it's probably still useful.
jsharf··on Ask HN: What is wrong with dating in 2022?
While I agree with this sentiment, there was a lot of harassment and toxicity with the old version. It made it too easy to find someone's profile if you knew them in real life. This reminds me of the "old facebook" too, which I miss, but stalking was a problem and it's probably for the best that things changed.
jsharf··on Web3 and crypto skepticism is growing and people are finally starting to listen
Usually I hate skeptical mean comments like this on hackernews. Right or wrong, there's a certain level of empathy missing.

And yet... In this case I find myself guiltily agreeing.

jsharf··on Direct conversion of CO2 to solid carbon by Gallium-based liquid metals
Are there any chemical carbon configurations more stable than CO2 which are solid?
jsharf··on AI training is outpacing Moore’s Law
Unless we have widely available pre-trained models with generic knowledge that is easily transferable. Such a thing is obviously difficult, but it isn't impossible if we're talking about the future.
jsharf··on The Greedy Doctor Problem
Pay the doctor a fixed amount each month that increases as you get older. Sure he makes X right now, but if you live past 100 he could making 5X that.
jsharf··on Doctors Might Have Been Focusing on the Wrong Asthma Triggers
These are idle cars which are not braking, so the PM2.5 here is purely the engine pollution. City life might not be affected as much, but school buildings with cars waiting outside will be!
jsharf··on GitHub’s AI Copilot Might Get You Sued If You Use It
Honestly it seems a bit like an overreaction. The author found a single person who is leaving GitHub over it and they're waving it around like "some people" are leaving GitHub.
jsharf··on Human Rapamycin Longevity Clinical Trials Begin
Well, if your life is extended, it'll definitely happen within your lifetime ;)
jsharf··on Netanyahu is out as new Israeli government survives confidence vote
"stick together long enough....", I don't think that's going to happen. There's no way this government will last 2 years, I doubt it will even last 3 months.
jsharf··on Building a Space-Based ISP
The alternative is waiting literally 10-20 years for anyone else to catch up.
jsharf··on White House eyes subsidies for nuclear plants to help meet climate targets
Yes, but maybe steel is more essential to society than burning natural gas. But natural gas companies make more margin so they can afford the carbon credits, meanwhile steel has tighter margins so it gets passed to the consumer. This means it might disproportionately limit the consumption of things based on how much money they make. This is all fine until construction becomes more expensive because you can’t easily get the steel you need for buildings (what if you were trying to build a clean energy power plant and. Is it’s too expensive?). Some things are essential and need protection from the free market (ex, hospitals have diesel backup generators. Those would become more expensive). You could add a government subsidy for steel, but now you’re stacking laws on top of each other and playing centrally organized government. Which doesn’t work well.

The downside to having separate laws per industry is that you’ll get insane workarounds (see import tariff law). Carbon is carbon — so workarounds are easy. For example if natural gas is taxed higher than steel, you’ll have natural gas companies producing just enough steel to be qualified as steel production companies so that they get the lower rate. Or something like that.

Choosing policy is tremendously difficult. We could deliberate all day. despite what I’ve said, a carbon tax is better than doing nothing, and we would be wise to start creating/increasing carbon taxes already.

jsharf··on Why A.I. Moonshots Miss
This is just redefining what counts as "real intelligence" to raise the bar.

Once we have computers that can think like humans, there'll be people saying 'oh, it's not real "understanding", it's just generating speech that matches things it's heard in the past with some added style', not realizing that the same also applies to human writers.

As long as the bar keeps rising and we've found business applications, there will be no AI winter.

jsharf··on Fusion startup plans reactor with small but powerful superconducting magnets
haha this gave me a chuckle. underrated comment.
jsharf··on Israeli study finds 94% drop in symptomatic Covid-19 cases with Pfizer vaccine
Israel has many different population groups.

The Haredi population is acting like covid doesn’t exist and has insanely high numbers of cases.

I suspect that despite the vaccine working well on your everyday science-trusting Israeli, the Haredi population is throwing off the average significantly.

Source: I have family there.

Recently the police tried to enforce the lockdown Bnei Brak (a city with a lot of Haredis). The Haredi rioted against this, yelled “Nazis” at the police, and burned down a bus.

jsharf··on GitHub Should Start an App Store
Along these lines, it would be really cool to see GitHub begin to approach the source code infrastructure that Google has internally. If they added a good build system (heck, just use bazel) and a feature to build code in the cloud (of course, all with open protocols — it’s git after all), we could have a much more standardized open source environment— the overhead to working on a new open source project would be lower since you wouldn’t have to figure out how to build it or how to build dependencies. It would also make it significantly easier to add dependencies and integrate software together.

Along these lines, it would be really cool to see GitHub begin to approach the source code infrastructure that Google has internally. If they added a good build system (heck, just use bazel) and a feature to build code in the cloud, and a web IDE and better code review system (of course, all with open protocols — it’s git after all), we could have a much more standardized open source environment— the overhead to working on a new open source project would be lower since you wouldn’t have to figure out how to build it. It would also make it significantly easier to add dependencies and integrate software together.
jsharf··on Your Move, iPad
Apple should really converge the ipad and macbook. Having something like a surface book where there's a laptop/desktop experience with a thin, light, detachable touchscreen and full desktop software would be really nice.
jsharf··on Hemingway Editor
My experience with Hemingway in the past has been that it's a set of general heuristics which prevent bad writing. I found it quite helpful to proofread. It's not a replacement for a human editor, but it's a step up from traditional autocorrect.

At the end of the day, it is still up to the writer which suggestions they keep. Anyone who blindly accepts suggestions because the tool recommended them probably wasn't in the correct mindset to write well anyways.

jsharf··on Hackers extorted $1.14M from UCSF
But at least it's difficult and illegal. It makes them less of a target for hackers since they're less likely to pay and it places liability on anyone who tries to work around the law.
jsharf··on Markets are efficient if and only if P=NP (2010)
lol
jsharf··on “Less than one”-shot learning
To me, this seems similar to training a neural network on 10,000 images and then publishing the weights themselves as a distilled "image" (of course, it's not the weights themselves but a "distillation"). I feel like you could get something similar by taking the trained network and then applying deep-dream techniques for each classification label on a blank canvas.
jsharf··on We made an open source ESP8266 dev board for makers
Esp8266 is a microcontroller which is incredibly popular in the maker/hacker movement for it's low cost and wifi integration. You can add a relay to this microcontroller and put it on your wifi network and use it to switch appliances on/off from the internet quite easily. If you read hackaday, you'll run into esp8266 projects regularly.

It's a bit harder to get started with than your average arduino project. If you want, you can use the Arduino IDE which hides a lot of the complexities. But the docs from espressif are aimed more at the firmware engineer crowd, so if you want to get serious there's more of a learning curve (IE nvflash partitions, understanding what a bootloader is, etc). Also, you'll probably end up getting into freertos at some point, which further complicates things. But it's a super great module for home projects.

The esp-32 is a newer chip which is similar but adds bluetooth. In general you're better off going with esp-32 nowadays -- it's got a second core as well.

Until recently the only thing missing was USB (though there were bit-banged USB implementations!). But now there's an esp-32 with USB too, so really for the cost, the features are unparalleled.

If you're okay with things not being as polished as the Arduino experience (you might have to learn "real" firmware programming), it's really the best starting choice for your side projects.

jsharf··on New Zealand is about to test long-range wireless power transmission
Wow, it's cool to see all of the collective knowledge that people bring to hackernews comments. Very interesting questions! Hope Emrod answers them.
