Deepseek Coder Instruct 6.7b has been my local LLM (M1 series MBP) for a while now and that was my first thought… They selectively chose benchmark results to look impressive (which is typical).

I tested out StableLM Zephyr 3B when that came out and it was extremely underwhelming/unusable.

Based on this, Stable Code 3B doesn’t look to be worth trying out. Guessing if they could put out a 7B model which beat Deepseek Coder 6.7B they would have.
SF doesn't seem like an ideal place, it rains and is foggy which both degrade lidar performance.
Well... except that explanation only arrived 20 minutes after the original video, after people began pointing out the deception.
I usually help bag my stuff if there isn't someone there already to help. I really don't mind and it gets me out of the store faster + helps the next person get through faster. I don't understand the mentality of just standing there helplessly waiting for someone to come. It's really not that difficult. It feels like the same energy as folks who can't be bothered to throw away their trash at counter-service restaurants and cafes that do not actually have people whose sole responsibility it is to bus tables. Is it really putting one out that much to carry their coffee cup and napkin with them as they walk right by the trash next to the door on their way out?

NL2SQL is a solved problem Not [CIDR 2024 paper] [pdf]
Okay, then it's clear why Epic couldn't do anything.
The thing about machine learning is that it can fail very suddenly, in a very unhuman way.

So even if self driving works most of the time, it takes a lot of work to address weird edge cases even the most inebriated human would not mess up, that other drivers/pedestrians would not anticipate.
It works most of the time but the issue is that "most of the time" is not good enough for these systems. Even if the failure rate is <1% that may end up being lots of accidents and deaths at scale.

People often make arguments that "oh it will still be less accidents than human drivers", which is true, but, the problem is that human accuracy is a very poor benchmark for autonomous systems. Autonomous systems need to be held to a higher bar, and it's better if that accountability and expectation is held from the beginning.
Let's say Spotify adds this in-app message: "Buy with Apple Pay, or visit our website and pay 20% less". No links, just simple text. How would anybody be able to produce a "clear paper trail"? Spotify can only say the total number of web purchases. Apple has no choice, other than to guess how many people would have bought through the app store instead.

If they decide to ban these kinds of messages, and only enforce link tracking, that would be directly in conflict with the ruling.
Yeah have fun when it's snowing so hard that all the sensors get covered if you stand still for too long at a light or something.

And I do wonder what hail would do to it. Could cause a lot of... interesting input data. And subsequently a lot of interesting driving.
In Germany you always bag everything yourself and in the discount stores you have 1.4 seconds per item to pack stuff while the cashier is sliding stuff towards an area of maybe 60cm x 100cm (2 feet by 3 feet) where if you bag it too slow you'll hold up the line and people will look at you.
My reference was the "System V Application Binary Interface" itself (chapter 4). It's not that difficult to grok.

I just took another quick look at my Rust code and Python's C code. It looks like they try to avoid allocating/acquiring a Mutex in the short case. I wonder if that could be part of the problem. Allocating a Rust Mutex should be ~free on Linux, but acquiring it will be a SeqCst compare-exchange...

Edit: My code avoids acquiring the Mutex in the initial constructor and only takes it in update(). Are you using update() in your benchmark? If you tweak it to avoid update, does it affect the numbers?
They are testing, but don’t offer a service in snowy areas yet.
...That's rude.

A Walmart I visited recently had a camera at ankle level specially to show the bottom of your cart for the cashier to see.

Another store (I forget which) had a full cart camera and prompted me to check my cart for remaining items because I had unused reusable bags in it.
You cannot pay taxes or do anything legitimate with crypto.

Sounds pretty useless to me.
2fa means BOTH factors are needed. the situation you are discussing here is not password and email but password or email. either one would work.

i have seen services that send a token to your email every time you log in or when you log in on a new device or when you haven't logged in in a long time. that would indeed be a form of 2FA. but these services also allow you to reset the password through email, so it's not exactly 2FA all the time like most other 2FA setups.
One angle is to look at when we expect there to be data showing a new autopilot vehicle is at least equivalently safe to a new non-autopilot vehicle with modern ADAS. I don't think the performance is there yet, hard to tell when it will be.

Then get rid of it. In the US, you’re not obligated to have insurance and are free to gamble on your continued good health and save your premium money for a black swan health event.

Or, alternately, look up the word “insurance” and realize what its purpose is.
Barring a laundry list of technological breakthroughs, space based solar power will not be practical in our lifetimes. I recently did a lit review in this area, and it's pretty clear that this is a pipe dream for a small group of people that seems to attract bursts of grant money in 10-20 year intervals before collapsing when the people picking up the tab realize what the challenges are.

There are a few extant concept designs for space based solar power, but the most mature and most representative example is a design called SPS-ALPHA [1] which came out of a NIAC contract and has been refined by its inventor in the intervening decade. Essentially, the architecture assumes a large
structure supporting an array of mirrors in geostationary orbit focused on a sandwich panel. One side of the sandwich panel contains solar cells, the other contains a retrodirective phased array which beams the collected power back to a site transmitting a pilot signal on earth.

This design is interesting and solves some issues that plagued the original designs developed in the 70s. The sandwich panel avoids the need to collect and transfer power between separate solar panels and an antenna, and the retrodirective array avoids the need for precise subwavelenth position knowledge of array elements across the antenna. Using mirrors also reduces the number of solar cells required, however, the achievable concentration ratio isn't very high (3x or so IIRC) due to thermal constraints requiring the sandwich panel to passively self-cool. The mirrors are gimballed, allowing the design to maintain peak power generation regardless of the position of the sun.

The problem is the sheer size of the structure, and it is dictated by physics constraints. Efficient microwave power beaming over a fixed distance imposes an inverse relationship between the size of the transmitting and receiving antenna: halving the area of the space based antenna doubles the area of the earth based antenna, and vice-versa. Both antennas can be shrunk simultaneously by increasing the frequency of transmission, however, atmospheric absorption caps efficient transmission at around 10 GHz. Most designs, including SPS-ALPHA, assume a 2.4 GHz transmission frequency (probably because of the ISM band and the feasibility of building high efficiency saturated amplifiers in this band). For SPS-ALPHA, this leads to an antenna about 1.7 km in diameter in space and 5 km in diameter on tbr ground.

Here's the key part: these dimensions are independent of the amount of power transferred. For efficient transmission, you need to build a spaceborne megastructure regardless of if you're transmitting 1 MW or 1000 MW. You can't really do a small demonstration plant, you pretty much have to go for the whole meal deal. And that structure is huge: the largest thing we've ever built in space by several orders of magnitude, in a very hostile radiation environment (GEO). The costs would be incredible.

Could you build it? Technically, yes. But there is no universe in which it makes economic sense.

This story just gets worse and worse. Interesting that Sunak only promises to try to overturn convictions and get some kind of financial remuneration for victims, but no discussion about having a investigation into how this structurally happened in the first place and figuring out who needs to be punished for coming up with these incentives in the first place?

You are free to think so, but it really doesn't make you an artist any more than wearing a medal you bought second hand makes you a war hero.

Something else did the work and you're just claiming credit. It's honestly kind of sad.
Are there any vision only self driving cars on the road?
You’re wrong on most counts.

1. Waymo costs around $120,000 and the cost is rapidly dropping with new hardware generations and vehicle platforms. They’re in LA, soon in Austin, airport rides in Phoenix and imminent highway driving.

2. Tesla and Comma are only L2, not even L3.
Ask HN: How long can a company keep product in repair?
I bought a monitor which broke in just 4 months and has been under repair for over a month in company's repair center. They still don't have any estimated date for fix and will not replace or refund. Is there any law (in US) which a consumer can use for protection against this practice? What option does a consumer have?
It is extremely common to have a collection that might or might not be empty at runtime, and we don’t want to force every programmer who allocates a slice to manually write an alternate code path for the empty case.
>> a future in which capital concentrates even further into the hands of a few technological elite who make their money off of flouting existing laws and the labor of thousands

I think this is the central issue and is not limited to just AI generated art. Wealth concentrates to the few from each technological development. When robots replaced factory workers, the surplus profit went to the capital holders, not the workers who lost their jobs. AI generated art will be no different but I don't think it will replace the creative art that people will want to make, just the art that people are making to pay the bills.
Agreed - that's been a huge annoyance to me as well. What's worse is many of the self-checkout stations around where I live used to accept cash, but the stores have been transitioning a larger and larger proportion of them to card-only.

Another annoyance I've run into at one store in particular is that the self-checkout machine no longer pre-calculates the tax amount. Now, I have to hit the pay button before I'm given the true amount due.

The self-checkout machines are getting worse over time. It's quite reminiscent of how ATMs have evolved.
Not familiar with tc, but from an online search they seem similar.

Cruise has Teleoperators. Their snafu revealed an intervention every 4-5 miles, which is worse than Tesla's FSD. (Cruise vehicles were also subjectively bad at driving)

Leveling means nothing, and are determined by the company. Actual operations and range of operational capability matter.
What company in tech has unpaid internships? They’re paid less, but they’re still paid in any tech firm I’m aware of.
This can’t be the first time a company has tried to have a layoff without calling it as such. I have to believe there is legal precedent that a forced relocation is the same as a layoff.
“behoove” in a discussion about tech and the military is where worlds collide. The favorite word of mixed-ly educated, immensely powerful senior enlisted. I’ve been told what behooves me many a time but this is the first time that AI has behooved me.
Where I work, yes, internship places have been massively reduced. Internships feed into the hiring pipeline: no hiring, no internships.

They're not a way to get low cost employees, since even very adept interns need a ton of guidance and help from the people around them, and that takes time from the full time employees hosting the interns.
I sure hope so, Russia has 100% been doing it, with multiple documented „botfarms” (more like fake identity verification farms)

And Phoenix, and very soon LA, and very soon Austin. They're expanding, not staying in one spot for eternity.

> Meanwhile Tesla and Comma (both pure vision) are the only operational L3 systems being used every day by regular people to drive millions of miles.

What a coincidence, because L2 (what Tesla actually is) to L4 self driving are millions of miles away from each other.
> A ton of what the foundation does is provide incentives for both government and NGO aid-services to stay locked into Microsoft products

Wait, is that documented? The foundation will only give you money if you use Microsoft products? Or they won't officially do that, but potential grant receivers have had foundation representatives strongly hint it would be better for everyone if they kept using Microsoft products?

Because that's a pretty big claim to make otherwise.
World peace incoming
Yeah, I just think that is kinda a garbage perspective.

If your perspective is so great that everything is arbitrary simply because it is the product of the human mind, then the term is meaningless. why bother even using it.

Similarly, if someone treats every definitions as fluid, and makes no attempt seek logical or objective consistency, I don't see the point in conversing with them.

I will just assume the true meaning of everything you said is enthusiastic agreement. If you disagree, I can waive your point away as the arbitrary and pointless ravings of a human mind.
I never experience phantom braking in FSD Beta on HW4.
Just took a Waymo ride across San Francisco 3 nights ago in hard rain, at night. A hilly complex city with bike lanes, kinda oddball medians and bollards, many pedestrians, and homeless people wandering down the middle of streets. It did great.

Even if it didn't work in snow (and it's unlikely to do worse than humans), all the west coast, desert west, and south have basically zero snow all year long.
This has already been the case for primarily fitness oriented GPS watches / heart-rate trackers / etc for some time. Bluetooth, but even longer using ANT+, which is quite a bit more battery efficient.
Man so this has been an issue for 20 years, we suddenly invent LLMs and you want your money back on Nvidia.
These are great questions, and ones we’re very curious about as well. I don’t believe that our current Chapel team has much experience programming NNs and LLMs, having focused on other areas. That said, I’m also not aware of any intrinsic barriers to implementing such algorithms in a portable way within Chapel, potentially calling out to vendor-optimized implementations when available and appropriate.

If you, or others, would be interested in exploring this topic, we’d be very interested in either partnering with you or supporting your efforts.

The ACA was a fantastic tool, enabling millions more people to access insurance that will actually pay things. If this is your analysis, my assumption is that you work in a healthcare adjacent world like BNPL and don’t actually have even the vaguest understanding of what the ACA is, does, or includes.

We can start with the simple fact that catastrophic plans still exist and that they actually cover things, now. That you think they both don’t exist and we’re somehow better before defies belief.
Phantom braking has been almost entirely eliminated in the past year. Plenty of others have noted the same experience.

Used to happen to me once every ~100 miles. This year, it only happened once the whole year, and the drop was maybe ~10mph.
> I wouldn't mind these machine so much if they always accepted cash. The problem is that more often than not they don't.

Ooof. I haven't seen a SCO with no cash capability. I know cash-handling equip costs but if they don't want pay for that, they might need a cashier.

Walmart may have a couple SCO that won't do cash temporarily - but there will be 10 more fully working.
>There is some radiation with some designs, but the basic idea of fusing hydrogen into helium works without radioactivity.
Per unit energy D-T fusion, the fusion reaction most likely to be viable near term, generates more neutrons than the fission of U235. The U235 fission reaction[0] releases 3 neutrons and 202.5 MeV of energy, 8.8 MeV escapes as antineutrinos, so let's call it 193.7 MeV, so 64.5 MeV per neutron.

D-T fusion generates 17.6 MeV and 1 neutron, so 17.6 MeV per neutron. So for the same amount of energy produced it makes about 3.5x more neutrons. Worse yet, in D-T fusion, 14.1 MeV of the energy released is in the kinetic energy of the neutron. Compare this to the 8.8 MeV energy of all three neutrons in a fission reaction. Neutron activation and damage are significant engineering concerns for fusion reactors.

wow! Looks like Apple finally caved.

This is a huge win for the developers, despite that pesky warning. They can still ask users to circumvent apple pay/in-app purchases and get away by not giving a revenue cut to Apple.
How would that work? From my previous comment, let's say you add this message (no links): "Buy with Apple Pay, or visit our website and pay 20% less". Nobody knows how many users decided to visit the website instead.
Can anyone explain what’s Stability’s business model (or plan for one)?

I get why Meta releases tons of models, but still can’t quite understand what stability is trying to achieve
I don't know why they'd need OpenAI though. Our government's three letter agencies must have a one hell of a data set to train their own AI on.
4) a seat heater ALONE is useless in frozen cold, you need much more, and much more means much more power...

6) some example: I have an EVC300400300 witch offer also a bad integration with my p.v. (bad, because badly designed by Victron), I do not count how many times my car refuse to charge or by EVC refuse to allow charge because of crappy communications between the two and ZERO control on my side. I have HA who handle as much as I can in the actual crappy state of crapIoT but nothing I can do with anything not made to be integrated. Cars actually are one not made to be integrated, even if they offer also V2L, crapplications for remote control and so on. The are just designed as a rolling data collection device, controlled by the OEM not the formal owner. To came back on topic I simply can't makes my car heat the battery when I want it heated to use it in the early morning, there is no way to do so. The car decide autonomously when to heat and the EVC decide autonomously if allow it or not, so the resulting behavior is NOT MUCH BASED ON ACTUAL TEMP but on random interaction behavior between two badly designed devices. That's is.

7) it's not a matter of mere horsepower or torque, with a mechanic gearbox I can dose the torque, with an EV I can not. It's the same when parking in tight places, arriving slowly to nearly kiss another vehicle bumper is easy with a mechanic gearbox, next to impossible with an electric motor. At least not if I can't both accelerate and break a little bit in absence of something better.
Phew. I was getting scared that someone would use it to cause instability.

So Apple will be collecting 27% (instead of 30%) for... what exactly?

They might just get away with something as crass in a vacuum, but given that the DMA will go into effect very soon, there will be a point of reference in a similar economy, and I don't think it'll be pretty for Apple.

US regulators (federal or state; I could see something equivalent to GDPR and CCPA) will be taking a very close look.
I built a home-grown scanner like this one (not with ZBar though) for my asset tracking web app (www.assetbots.com) and agree that for 1D barcodes a cheap bluetooth or USB scanner is hard to beat.

Russia doesn't need fancy "AI" to do this. Human operators and a few well-designed scripts make botting very easy.
Tesla doesn't have self driving though. Its level 2. Mercedes has level 3 cars on the road where the driver can legally watch a movie or read a book. Level matters but it dictates what the driver can legally do. Also Mercedes is accepting 100% liability while their cars are in self driving, Tesla makes the driver 100% liable. There's a huge difference.
