If the people who have the most to lose don't think that something is in the national interest, then is it really?

"think" is doing a lot of heavy lifting in that sentence. Are the people really thinking? I don't think they are.

Some unsolicited feedback:

I think the appRoute macro obfuscates the types and signatures, and introduces some unnecessary indirection. I would get rid of it.

Related, the AppContext type could be renamed RequestContext or ControllerContext or something as its App + HTTP Request + DB and not just the App.

Otherwise, I agree with other commenters that this is some of the cleanest C code I’ve seen in a while! Great effort!

I have always wondered how this works (along with wire bonding), especially in an economic way.

Chips being cheap makes sense at the lithography / wafer level because sure, you can stamp out thousands of them at once. But once you need to dice them up, bond wires to them, and package them... how on earth do you do that so efficiently that each chip can be sold for fractions of a cent?

If you can shine lasers at them to etch out a chip trace, then you can shine lasers to carve up the chip. Just use stronger lasers.

On a related topic: Anyone want to sign up for a HN meet up in Hong Kong. I have read at least a few expats on HN said to be working in HK. Not sure if there are many more of us.

I’d be interested.

Go do an actual sleep study some time. You'll be hooked up to a ton of sensors, and in the morning a group of doctors pour over the results, and they'll basically vote to decide on what the data means. "Oh this looks like REM".

So, to calibrate a sleep tracking device, you have a person wear the device, while also doing the sleep study. You do this a bunch of times. You train some ML models to try and make the outputs from the sensor data, after processing, the same as the study data.

After some degree of accuracy you declare success.

Now, does it work? In broad strokes, yes. You can (easily!!) see the effect of alcohol on sleep quality. If you have a crap night vs a good night, sure, a wrist based consumer device can figure that out.

Actual details? Eh. I wouldn't trust the devices for anything but directional data.

The more sensors devices get, the better than ML model can be trained.

Now it has been awhile since I last worked on this stuff (I actually just sat next to the people doing the work), so maybe there is some revolutionary new technique out there, but if not, it is still ML models trying to correlate things and match them up to what a bunch of fancier sensors said during studies.

Typical watch based sleep trackers and even my Withings sleep pad can’t really track my sleep properly, particularly REM sleep. I think I move too much. I bought a Dreem2 EEG device that measures brain waves and it could detect my REM sleep correctly, and determined that my sleep is actually fine, not great, but good enough.

I had bad RSI for ages. What helps me and other comments have agreed is pulling excercises. Specifically I have a bar at home attached to the ceiling. Just hanging from the bar as long as you can and doing that regularly seems to stretch out the right muscles/tendons. Don't over do it but at the beginning I could only do 20 seconds. Now I can hold on for 1 to 2 minutes depending on the day.

I have very little wrist pain any more.

I also have a kinesis pro keyboard and a MX master mouse. They both add to the improvement.

Flip side to this, is I’ve had Carpal Tunnel for a while now, had surgery 2 years ago. It’s somewhat better and I am now active at the gym and in general it has helped a lot but extreme gripping such as deadhangs, deadlifts and heavy rows actually aggravates my symptoms. I started using straps for any weight over 50kg and my hands have got a lot better.

I’ve found that when you’re going from (weak, sedentary) => (strong, active) it can sometimes be difficult to discern what activities are good or bad for your pain. Sometimes you need to work through pain to find relief and strength on the other side, but sometimes working through pain just leads to more pain. The boundaries aren’t always clear at the time.

J.R.R. Tolkien himself sold the film rights to United Artists.

Also, for what it's worth, it's hard to imagine a better executor than Christopher Tolkien. He basically spent his entire life serving his father's artistic interests.

I honestly find this quite sad. Dude should have lived his own life, but instead lived in the shadow of his father.

As we improve the accuracy of automation and now the neural network, once laughed as a toy idea, does cough up something half decent, people ask "But who take a responsibility when things get wrong?" My answer is nobody.

These software giants never take a responsibility of wrongful automated result for decades but we keep using it.

Meta doesn't have an incentive to fix this case. It costs them manual labor of many manhours that outweigh the ad revenue from this person.

It probably keep this way.

It seems the notions of accountability and responsibility have broken down when it comes to AI. Any given AI should have clear lines of delegated responsibility from an accountable flesh and bones human. Any decision made by an AI should be marked as such and provide a channel for the decision to be reviewed by said human or a human delegate thereof should scope (in Meta’s case) be large. If it’s too much work to manage the reviews, tough shit.
faichai commented on Ask HN: When LLMs make stuff up, call it 'confabulating', not 'hallucinating'    · Posted by u/irdc
BaculumMeumEst · 2 years ago
Similar suggestions have been made over and over, and they've never stuck. "Hallucinating" has already hit mainstream media. It's probably going to stay that way out of sheer inertia because nobody outside of a small group of nerds on hackernews is going to sit down and think about whether "hallucinating" or "confabulating" more accurately describes the nature of the error. The existing term already captures the general idea well enough.
faichai · 2 years ago
Hard disagree. I’m browsing the internet not surfing the Information Super Highway. Mainstream media needs to rely less on allegory once technology becomes mainstream.
