> WRAP YOUR CAMERA AROUND YOUR WRIST AS YOU GO FROM MEETING TO MEETING.

Who wraps their webcam around their wrist to go to a different meeting? I just don't understand the target of these ads/marketing.
I’m not saying LLMs are good for nothing, I just think the class of problem they are good at is not a match for the current rhetoric.
I generally agree, but don't all the latter items simply in the end have the desired result of deterring future criminal behavior?

If distracted driving was caught 95% of the time, and the sentence was something like 40 hours of community service (and escalated for repeat offenders in some manner), I don't think society has nearly as difficult of a moral problem on it's hands when a 19 year old kills a cyclist due to checking a text on their phone.

Studies repeatedly show "random" punishments (even if harsh) are simply not very effective vs. consistent enforcement. When you drop the hammer on someone who more or less got "unlucky" that day by engaging in what amounts to otherwise normalized behavior due to lack of enforcement - it gets kind of hard to see how that can be remotely effective at accomplishing much for society beyond vengeance. While that is important, it certainly isn't everything.
Yeah, of course, this is a low-cost alternative, since you have to use your own camera or phone.

You clearly seem hung up on one country over another, and continue to ignore the specifics of the situation or any nuance to the situation. I think that speaks volumes. Especially when Dreamworks TV has been heavily outsourced based since the beginning. Just look at how many of their shows are produced at Bardel in Vancouver.

Anyway, agreed there's no point arguing with someone who has no actual roots in this industry. Have a good day, I hope your partner finds work soon, but maybe don't place the blame where it doesn't belong.
> reducing speed can improve throughput when congestion is happening

no, consistent speeds improve throughput, jackasses can, and do, tap their brakes at reduced speeds.
I believe you my surprise is more that someone would admit to making such a damaging choice for such a pathetic reason.
> But instead of reducing demand, more poachers may enter the market, because the high value of the tusks means they can make more with less work. The cost of the good is not related to its real-world rareness, but to the cost of paying people to obtain it, which may be high or low.

This doesn't rationally follow at all.

The rareness (low supply) of a good is the net sum of how hard it is to obtain, due to all the possible reasons for that.

More poachers may enter the market, but with fewer elephants left alive, they cannot find elephants so easily, which means it takes more time and effort: the MTBE (mean time between elephant) goes up, making the hunt more costly. They may have to engage in increasingly hostile and violent turf wars with other poachers.

More poachers entering the market will not prevent a reduction in demand; it isn't something "instead of reducing demand".

If the market maintains the same level of interest in the good, the demand curve stays the same, and the only thing that changes demand is the current price point, which determines where on the demand curve the market is.

The author of the article doesn't seem to understand the difference between a reduced demand due to a movement of price along the same demand curve and actually reduced demand, whereby the market is less interested in the good, and buys less of it at every price point.
Is there somewhere to see historical forecasts?

So not "the weather on 25 December 2022 was such and such" but rather "on 20 December 2022 the forecast for 25 December 2022 was such and such"
According to google that process took several hundred million years. As long as we generate atmosphere faster than it gets stripped away, there's no problem.

Anyway, I think terraforming is getting ahead of ourselves. Step one is getting supplies to Mars. Step two is building a base there. Step three is making that base as self-sufficient as possible. Down the road from that we can worry about generating an atmosphere.
Tell HN: It's quite simple to deceive someone on Facebook Marketplace
I recently purchased a Herman Miller chair on Facebook Marketplace and, like anyone, was closely monitoring the UPS site to track my package. Everything seemed fine until I noticed that, while in transit, the seller instructed UPS to return the package to them. Now, I'm facing an issue where Facebook doesn't allow me to file a claim. Every attempt results in the same response: "The seller has already shipped your package." I was surprised at how easily one can be scammed on Facebook Marketplace with such an obvious trick.

Funny to mention. None of the AI forecasts can actually predict precip. None of them mention this and i assume everyone thinks this means the rain forecasts are better. Nope just temperature and humidity and wind. Important but come on, it's a bunch of shite
I had a girlfriend who would get visibly anxious in the grocery store line if she hadn't introduced herself to the person in front of her. People were often shocked when she would randomly introduce herself, but it often turned into interesting but brief conversations.

When I moved overseas, she told me that I should do it, and I do on a regular basis - though not in the grocery store line, and I don't get anxious if I don't do it.

I've definitely made some interesting connections, including with a guy on a bus in 2012 who transferred me my first bitcoin on that bus and got me into crypto. I wish I knew he was so I could thank him.

I've never regretted reaching out to a single person. Sometimes people don't want to talk, and that is easily noticeable. Sometimes I don't end up wanting to talk to them, and that's a bit harder for me to exit.

Give it a shot, but do be conscious of other people's feelings and understand quickly if they want to be left alone.

As the update only affects infotainment and not critical systems, it seems like a reasonable tradeoff to me. Just because a car can fail in ways that kill people doesn't mean all parts of a car are equally critical.
Both APIs use weather models from NOAA GFS and HRRR, providing accurate forecasts in North America. HRRR updates every hour, capturing recent showers and storms in the upcoming hours. PirateWeather gained popularity last year as a replacement for the Dark Sky API when Dark Sky servers were shut down.

With Open-Meteo, I'm working to integrate more weather models, offering access not only to current forecasts but also past data. For Europe and South-East Asia, high-resolution models from 7 different weather services improve forecast accuracy compared to global models. The data covers not only common weather variables like temperature, wind, and precipitation but also includes information on wind at higher altitudes, solar radiation forecasts, and soil properties.

Using custom compression methods, large historical weather datasets like ERA5 are compressed from 20 TB to 4 TB, making them accessible through a time-series API. All data is stored in local files; no database set-up required. If you're interested in creating your own weather API, Docker images are provided, and you can download open data from NOAA GFS or other weather models.
I built a whole remote software update mechanism for a control binary that ran on 25k+ servers across multiple data centers.

Rest assured that after the first time I messed it up (which required ssh into each box individually), I wrote a lot of unit and integration tests to make sure that it never failed to deploy again. One of the integration tests ensured that the app started up and could always go through the internal auto update process. This ran in CI and would fail the build if it didn't pass.

While I fully understand that this is hard to get right 100% of the time, a mess up of this level by a car manufacturer is pretty amazing to me.
They're using predictive models to decide which experiment to do next. It's as AI as anything else.

> The OER is a thermodynamically uphill reaction involving four consecutive oxidation steps and O–O bond formation, which requires an applied voltage of no less than 1.23 V to operate. The OER overpotential, which is defined as the extra voltage above 1.23 V required for catalysis to occur, characterizes the voltage efficiency of the electrochemical device. Therefore, we chose the measured overpotential as the primary target of our ML model in searching for the optimal OER catalyst10,11,12. We first created 29,902 unique compositions and simulated atomic structures of resulting high-entropy hydroxides (Fig. 2a) from classical MD simulations (Supplementary Figs. 11 and 12). The obtained structural features, such as averaged metal–metal and metal–oxygen distances (Supplementary Figs. 13 and 14 and Supplementary Table 2), are passed to previously established bimetallic hydroxide models13,14 (Fig. 2b) to determine the OER activity of each multimetallic hydroxide by DFT calculation. Three DFT-predicted OER activity descriptors—including the Gibbs free energy change of hydroxyl adsorption ΔGOH* (ref. 15) and differences between the Gibbs free energy change for oxygen adsorption and hydroxyl adsorption ΔGO−OH (ref. 16), the amount of charge transferred for hydroxyl adsorption on the activate site Δq (ref. 17)—and the paired composition information are used for NN training. As Fig. 2c shows, the NN model can accurately reproduce these DFT results. With the NN model, we can now rapidly predict the OER activity of high-entropy hydroxides obtained from any given composition of selected Martian ores (Supplementary Fig. 15), and these theoretical values are then connected with experimentally measured overpotentials. The ML model achieves remarkable accuracy in predicting true overpotentials (Fig. 2d).

The first TCP/IP Amiga stack was released in the late 80s called AmigaTCP (AmigaNOS) based on KA9Q TCP. All it had was SLIP, FTP and Telnet. I've never managed to get it going on my Amiga 500.

How to write a cold email (2020)
A ‘good idea’ where it is impossible to implement well, but easy to pretend to implement - in terrible ways - is actually a really bad idea.

As is a good idea (somewhere/some other time!) that no one can actually afford/doesn’t fit the circumstances where we are at, but we do anyway.

That is what I’m referring to. Communism, as an example, has a terrible track record beyond smaller communes (about 50ish, it appears). Folks I’ve met who push it as a good idea, call the larger scale failures problems with the implementation. It wasn’t done right.

It is also of course a common strategy for folks who are ideologically opposed to a new idea to sabotage the actual implementation of that idea, then declare the whole idea terrible.

I don’t know enough about the behind the scenes situation with the Oregon decriminalization to know if the treatment/rehab part of the effort was sabotaged or not, or actually went as well as could be expected, etc.

But time to design it and ramp it up, or evaluating if it would even produce useful/good outcomes or would even be effective (and what to do if it wasn’t) clearly wasn’t provided in the measure.

If they’re even now struggling to even get it ramped up, then that falls solidly under one of those three categories IMO. Feel free to pick which one.

Notably, these are the same issues that SF has been having with homelessness and drug use, among many other places.

Or if you think I’m wrong, I’m all ears!

Also half of these pedestrian-driver crashes involve someone (pedestrian or driver) being inebriated, but they certainly do occur when the driver is paying full attention.

> I've actually been in the crosswalk and had to stop for a right-on-red turning car who didn't manage to see a person in the street in broad daylight.

I've been in the same position as you here, but I've had a lot more drivers wait for me. I've also seen drivers (particularly in Florida) acknowledge my existence by making eye contact before rudely turning directly in front of me. This particular piece of American car culture drives me crazy, too, but is not an indication of broad negligence or disregard for the lives of others.

>Except it's plainly neither necessary nor sufficient.

Historically, the only times in which workers in developed countries saw gains relative to Capital owners is when they organized into large unionized formations during the Industrial Revolution and when the West was under threat from Soviet Union, both materially and ideologically. Since the collapse of the USSR, inequality has spiked massively and technological progress has become even more decoupled from societal progress.

And you’re correct about Stalin because the country was underdeveloped in its political economy and quickly devolved into totalitarianism under pressure from external threats. This eventually culminated in them attempting to speed-run a form of state-directed Capitalism, with its corresponding class formations (see Bettleheim’s book Class Struggle in the USSR). The same thing also happened in China, although more durably and shifted by about 20-30 years, relative to their revolution. Soviet and early CCP leaders were mistaken in thinking that you could leapfrog Capitalist development and thus both succumbed to its forces, the former externally and the latter internally.

Having moved to writing records by default in many places such as models and "DTOs", primary constructors are a very useful "transition" tool in those cases of "this started as a record, but now needs to be a mutable class for X reasons" and means a little bit less code to entirely rewrite in the first pass. It's also useful for even just "I aesthetically like for my class 'View Models' to mirror their record 'Model' definitions a little closer".
All this really shows is that it overfit to a common logic puzzle (which mind you lots of humans do).

The lion should go first in this one rather than the goat as it's the lion here that will eat the cabbage.
