In terms of a feature-set to target, would it make sense to be going after RPython instead of "real" Python? Doing that would let you leverage all the work that PyPy has done on separating what are the essential primitives required to make a Python vs what are the sugar and abstractions that make it familiar:

I haven't seen battery price quotes for retail customers for a while now, everybody I know who wants one has one. But not too long ago a battery bank including installation was easily in the range of 800 to 1000 EUR/kWh of storage.

Battery storage may become a bit of a no brainer from a purchasing price point of view, but I don't think it will actually be more beneficial for people, especially if BEV adaption continues at a similar rate and bi-directional charing becomes widespread

Not yet — I'm currently testing on a Zynq-7000 platform (embedded-class FPGA), mainly because it has an ARM CPU tightly integrated (and it's rather cheap). I use the ARM side to handle IO and orchestration, which let me focus the FPGA fabric purely on the Python execution core, without having to build all the peripherals from scratch at this stage.

To run PyXL on a server-class FPGA (like Azure instances), some adaptations would be needed — the system would need to repurpose the host CPU to act as the orchestrator, handling memory, IO, etc.

The question is: what's the actual use case of running on a server? Besides testing max frequency -- for which I could just run Vivado on a different target (would need license for it though)

For now, I'm focusing on validating the core architecture, not just chasing raw clock speeds.

I went through this exact thing. I became so depressed and stressed out during my last real software development job, after making it to a pretty respectable senior software engineer. I quit as a life saving decision, and now it seems that those 5+ years I put in just don’t matter, as I had been getting to the final hiring stages and then getting passed up constantly. In the other hand, I have been able to get into graphics programming, painting, 3d modeling, etc, because I don't have to come home and force myself to learn the new frontend/backend framework, I have a lot less stress and I have no desire to get back into the hamster wheel of the tech world. I love creating and building, it gives me a reason to live, I now know that I was preventing myself from this very important life satisfaction, which led me to my huge career impasse/quitting my job. I think some of us are just not built for the hyper optimization and materialism of the modern corporate tech world. I err personally more toward the artistic side, and that quality is not appreciated by the vast majority of recruiters and hiring managers. Like you, I am hopeful for the future, but I also no longer hold the delusion that I can find life satisfaction through the job alone, as I so naively pursued before. It’s so much harder to measure success when its not based on those simplistic metrics like company status or income, but maybe that’s because it never should have been the concern. :)

I don't like this example but in general I very much agree with you and find it a shocking that multiple people here do not.

It is plain and simply unethical to do such research on human subjects, regardless of how many other bots there are out there.

It is a matter of principal and ethical responsibility. I would have expected especially researchers to be conscious of this.

Thank God. People on the roads are extremely reckless and we don't do anything about it. Our highways are lawless for the most part. People can drive however they feel like it. You literally have to kill someone AND be drunk before you actually get in trouble and are locked up. If you kill someone sober though, it's totally fine under our current system.

In my opinion, if you get caught driving recklessly, the punishment should be that you're banned from operating 4 wheel vehicles, and only allowed to operate light 2 wheel vehicles like scooters where you will only kill yourself and no one else.

The automobile is not the primary mode of transportation simply because the US is "big." Its dominance stems from a series of deliberate, damaging historical and policy decisions, not inherent necessity or geography.

One critical example is the National City Lines conspiracy. Backed by the totally expected actors General Motors, Firestone, Standard Oil of California, Phillips Petroleum, and others, this group bought up efficient electric streetcar systems across the country. They were found guilty of criminally conspiring to monopolize the sale of buses and supplies to these captive transit lines. Their actions effectively destroyed electric rail to force dependency on fossil fuel buses and private automobiles; this was manipulation, not free market competition.

Furthermore, post war suburban planning deliberately engineered car dependency. Low density sprawl, mandated parking minimums, and strict separation of housing from jobs and services made car ownership non negotiable. This planning functioned explicitly as a "means test", using the requirement of car ownership to enforce segregation and keep lower income populations out of these new communities. This represents a significant shift, as most Americans relied heavily on non automotive transport until the mid 20th century.

This dependency was cemented by massive government bias towards cars. Trillions were poured into building roads and highways like the Interstate system, representing a huge subsidy for driving. Meanwhile, public transit and passenger rail systems were systematically starved of equivalent investment, left to decline, or dismantled altogether.

Therefore, the "big country" argument fails logically. If sheer size dictated transport, why not advocate for air travel, being far faster than driving cross country? The car's chokehold is strongest for daily commutes and regional travel, precisely the areas where robust public transit could thrive if it had not been actively undermined or neglected in favor of automobile ownership. The car isn't the default because it naturally "beats" other options in a large country, it is the default because the system was deliberately shaped over decades to ensure its dominance at the expense of efficiency, equity, and alternatives.

In my car taking the headliner off involves removing 6 bolts (one in each pillar) and then popping out some retaining clips. I was surprised at how easy it was when I ran the wire to the rear camera. Headliners were notoriously difficult to deal with in the old days. There was even space to tuck the excess wire away to keep it neat and tidy looking. My camera just sticks to the glass using a sticker so attaching it was no problem either.

Ah, I didn't know this. One of the prospective tools I had in mind was real time alerting in case of drastic drops eg ping doctor or relative. I think will have to be limited to the apps/tools that do support realtime.

This is a very big misconception about AlphaFold. It's not generating a structure totally de novo from sequencing. Instead it's primarily finding relationships on the sequence level to other solved structures. If those structure/sequence relationships didn't exist somewhere, AF wouldn't work because it doesn't really have much information about protein folding from first principles. There are some small de novo elements, but nothing really groundbreaking. Where AF's true strength lies is in it's ability to detect relationships we have been unable to detect with any other method.
by mlsu | 2025-04-28 15:23:13+00:00
The information needs to propagate through the network either forward (when the model has the codebase in context) or backward (when it updates its weights).

You can have the models pseudo “learn” by putting things in something like a system prompt but this is limited by context, and they will never permanently learn. But we don’t train at inference time with today’s LLMs.

We can explicitly reject this possibility by looking at the information that goes into the model at train and test time.
by quesera | 2025-04-28 15:23:47+00:00
No, not at all.

Alpha code with zero context is an utter waste of attention.

I must be confused about how y'all are developing software, because the path from "incompletely specified takeaways from a product design meeting", and "final product" does not pass through any intermediate steps where reduced contextual awareness is valuable.

Writing code is not the hard part.
by nonethewiser | 2025-04-28 15:23:50+00:00
In my experience, "vibe coding" can produce a rich prototype very fast.

Then as scope expands you're left with something that is difficult to extend because its impossible to keep everything in the LLM context. Both because of context limits and because of input fatigue in terms of communicating the context.

At this point you can do a critical analysis of what you have and design a more rigorous specification.
by gnfargbl | 2025-04-28 15:24:32+00:00
I don't see nearly enough complexity in this analysis to justify the claim of having found any insurance fraud.

Firstly, there's no account for correlation between the features identified. The article mentions VINs which have several single-vehicle accidents, for example, but someone who has one single-vehicle accident is probably more likely to have another. Switching coverage is another of those potentially-correlated features; if you claim and it bumps your premium, aren't you likely to shop around as a result?

Secondly, there's no attempt to account for the law of large numbers. It's incredibly unlikely that someone has three single vehicle accidents in a year, but because the probability of that is nonzero, we know that with enough vehicles on the road then someone is going to do it.

The article covers itself by acknowledging this, of course, but if you title your blog post "We Found Insurance Fraud in Our Crash Data" then you should actually do that.
by jandrese | 2025-04-28 15:24:57+00:00
I've wondered this too. Even if it's only the rear camera all cars should have a few seconds of rolling buffer that they save whenever an accident is detected. At the very least if the airbags blow it should trigger the save. You only need enough storage for maybe 10-15 seconds of footage.

I would also like the ability to turn on the rear camera when moving forward, for those times when the rear view mirror is blocked, especially on vehicles where the backup camera is integrated into the rear view mirror.

There's more than code to build a startup. I have found the best way for me to avoid burnout or alternatively feeling like i am behind is to set very high goals. Find a lifetime goal. Maybe it's making a startup, maybe it's something else. Everything you do should mostly fit into some super long term plan that could take an entire lifetime's worth of work. If you are doing creative or personal projects, these build skill and experience which will be needed by that long term project. Martial artists train by punching trees. To build micro fractures in the hand bones and increase the density and strength of these bones. Go punch your trees.

> Don't show me the average, show me the distribution.

Put another way, don't give me a measure of center (mean) without a corresponding measure of spread (variance/standard deviation).

Providing a measure of center for something that is approximately normal doesn't obviate the need for a measure of spread--you could have two distributions with the same mean but wildly different spread of results due to variance.

There was lots of prior art from the 80s for "write anywhere", which is a generally a consequence of copy-on-write on-disk formats. The write-anywhere thing is not really what's interesting, but, rather, not having to commit to some number of inodes at newfs time. Sun talking about NetApp makes sense given that they were the competition.

We don't know exactly what happened with Apple and Sun, but there were lots of indicia that Apple wanted indemnification and Sun was unwilling to go there. Why Apple really insisted on that, I don't know -- I think they should have been able to do the prior art search and know that NetApp probably wouldn't win their lawsuits, but hey, lawsuits are a somewhat random function and I guess Apple didn't want NetApp holding them by the short ones. DTrace they could remove, but removing ZFS once they were reliant on it would be much much harder.
by vessenes | 2025-04-28 15:25:47+00:00
Nice idea. Essentially, adding differentiability to the best of n choice lets them encourage models to add some diversity “naturally”. The Gemma 2b results indicate it’s probably worth trying this on larger models.

That said, I’m unclear how much this helps in practice; we don’t usually parse through say 32 responses from our 2B parameter models. I guess if you instrumented parallel reasoning processes in batch this might be helpful. Perhaps that’s what o1-pro is doing in the background, actually.

Anyway, this one seems to me like it might make its way onto the “good idea” list when rl is available in the training pipeline.

When type annotations are available, it's already possible to compile Python to improve performance, using Mypyc. See for example https://blog.glyph.im/2022/04/you-should-compile-your-python...
by mattkrause | 2025-04-28 15:26:06+00:00
The conclusion is a little too strong for my tastes. Changing coverage looks sketchy, but I’d bet people shop around after a crash and the ensuing rate hike.

Being involved in multiple accidents could suggest fraud but it could also just be bad driving, maybe someone very young or old.

It’d really help to know the base rates for many of these things: how often do people switch insurance, for example?

I really hate Linkedin as a content source. There are annoying colleagues whom I want to ghost, I don't want them to see any of my activities on Linkedin, such as liking a post.

I prefer anonymous social networks.

And people on Linkedin are very pretentious, marketing themselves for attention. There are good contents shared on Linkedin, but the platform is a bit insincere, like clubhouse.

There are basically 4 classes of amino acids:

Non-polar

Polar

Acidic

Basic

In terms of 3D fold - i.e. the general abstract shape of the protein in 3D, you can make loads of substitutions without changing it, generally as long as you stay within the same class.

It's not until you compare the 3D shape that you see the relationship.

In another life I worked as an engineer commissioning oil rigs and I’ve seen how tricky even a small-scale black start can be. On a rig, we simulate total power loss and have to hand-crank a tiny air compressor just to start a small emergency generator, which then powers the compressors needed to fire up the big ~7MW main generators. It's a delicate chain reaction — and that's just for one isolated platform.

A full grid black start is orders of magnitude more complex. You’re not just reviving one machine — you’re trying to bring back entire islands of infrastructure, synchronize them perfectly, and pray nothing trips out along the way. Watching a rig wake up is impressive. Restarting a whole country’s grid is heroic.

Well they do say they calculate propensity scores, but the whole language of the blog post is very hand-wavy. Warning over and over again that something is not causal proof, and then dramaticizing it as if it were proof is just unprofessional.

If you have a fraud model, just show the model and the data and the validation - everything else is marketing fluff.

No, they were suggesting attacking it based on speculation about this specific event, so yes out of thin air.

I agree that Russia is evil, but saying that it got away with it Scot free is just insane. In fact it even plays into Russian propaganda, to say that nothing really harmed them even after the past 3 years of international sanctions and consequences.

And western cowardice? Apart from nuclear war (which I'm glad people are being "cowardly" about), what do you suggest? It's also funny when war mongers online talk about cowardice. Why dont you go volunteer in Ukraine if you're such a non coward?

I did actually look a bit harder before I commented, I'm aware of how the media works. "Unleashing American Energy" pauses (cancels) all the "Green New Deal" programs as stated in the article. There was supposedly federal funding for a lot of new public transit projects that's now gone. Maybe it'll come back later, reframed as new projects... but I think that's extremely unlikely for a lot of this. The focus is now elsewhere.

Does anyone have suggestions for an simple audiobook/music player like this for the elderly and or those mild dementia? It should have large, tactile buttons, simple play/pause interface, volume control (ideally knob), and be able to read from sdcard or usb/

- I've used the Relish 'dementia radio' [1] before. Its a radio with support for reading from usb, but has no memory so useless for audiobooks. Very overpriced.

- The 'National Library Service for the Blind and Print Disabled' has excellent cassette type players [2], but they only take their cartridges. Ideally something this format but supporting usb/sd card

- Another comment [3] here suggests a smartphone with a macropad. this could work. they also built a custom solution.

Once upon a time crossing the street meant walking across a 20 foot road with the occasional small car going 20-25 mph. Now it's a 4-8 lane stroad full of 6,000 pound trucks that can't see anyone shorter than 5 feet past the hood going 50 mph.

How far will you let your kid walk from home alone?

Anyway my point is just that pedestrian deaths have gone up even as the number of miles walked and biked (_especially_ by kids - the modeshare for biking to school has absolutely plummetted) goes down.

I got a dashcam that ran off USB, which I knew my car had a port for on the center console. There's ways to run the wire under the trim for the most part, but it's a long run.. and at the end there's a part that remains visible to some degree.

There are cams that can do a rear view as well from inside the cab, which likely provides enough evidence if you're rear ended.

I only opted for a forward facing dash cam.

In my state, you are 100% at fault for rear ending someone unless you can prove your innocence -- which a dashcam can do assuming the person in front does something shady (like lane change + intentionally slam breaks).

However, do note that dash cams are not going to magically make rear ending the person in front of you somehow that person's fault. Virtually no one seems to leave enough follow distance by default because doing so means someone merged into the space.. and a dash cam doesn't shift the blame for simple rear endings unless it can prove some kind of malice or inattentiveness on the other driver (but even then, inattentiveness of the other driver is not necessarily a legal defense for you not leaving enough room to react.. perhaps if they stopped faster than a car could be expected to break, e.g. hit a concrete wall....) -- of course, laws vary by state

>there is a perception among many of lower socioeconomic status

I don't think this is it at all. In the US we don't enforce social norms. The public transit experience in the US is dominated by an extreme antisocial minority ("crazy" bums, drug users, bluetooth speakers, etc).

This is the true killer of public transit in America.
