Did the scientists deliberately break the bones of the rabbits to perform the tests? I understand that there has to be a necessary evil, and the rabbits here can at least recover from bone fractures, while lab animals in other research projects may get infected with some diseases and die painfully. Yet, I still find the scene of breaking the legs of the rabbits one by one quite troubling.

Anyway, I hope this glue gun project can finally succeed. My grandmother had a broken femur a year before she passed away. Although she could still walk with a walking frame after surgery, the irreversible loss of mobility was undoubtedly frustrating for her.

So what do you do if you have a better product and a "name brand" disadvantage? Advertising commodifies information flow instead of letting it pool with the people who already have access to it. Think of all the products that got big nowadays because they could convince VCs to fund ad spend, and saw a return for it.

I think advertising has a huge, positive, 2nd order effect on the world.

>They couldn't wrap their heads around the concept of casual crowdsourcing.

I'm sure they could, most teachers aren't idiots. And they were correct that "casual crowdsourcing" is not a fitting replacement for peer review.

And in fact, the current moderation policies for Wikipedia only work in so far as they use peer-review type processes, such as requiring "notability" and multiple sources, and preferring expertise in a field. Of course, if you're in a relevant field you shouldn't use Wikipedia as a primary source since you would presumably have access to whatever sources the wiki itself cites in the articles.

Protobufs are better but not best. Still, by far, the easiest thing to use and the safest is actual APIs. Like, in your application. Interfaces and stuff.

Obviously if your thing HAS to communicate over the network that's one thing, but a lot of applications don't. The distributed system micro service stuff is a choice.

Guys, distributed systems are hard. The extremely low API visibility combined with fragile network calls and unsafe, poorly specified API versioning means your stuff is going to break, and a lot.

Want a version controlled API? Just write in interface in C# or PHP or whatever.

Doesn't sound very profitable:

>Over the last two years, the state transportation agency has spent more than $62,000 on repairs related to guardrail theft in the region.

If the full cost of replacement is ~$31k/yr, the scrap value of the stolen guardrails is surely far less. Seems like there wouldn't be enough for even a single thief to make a living.

no, the post takes a shoddy quickly-made implementation of an attack and improves it to its own better implementation of an attack

neither are professional frontline research, because said frontline work has already been done long loong ago when Xorshift was popularized and definitely when it became javascript's *default* rng

This preening moralizing is precisely the problem. When you tell people they are "white supremacist-coded" they simply do not care. You are like an evangelical Christian telling me that if I don't accept Jesus I will go to hell. I just...don't care. I'm not mad. If anything I feel bad for you; I look at you and wonder how someone could devote so much of their mental hardware to this. Your statements do not make me feel guilty and like I need to change my ways. I am trying to convey to you that I do not share your moral worldview, and that your moralizing is completely ineffective. If you think that makes me a bad person, and you don't want to associate with me, that's fine. I don't care, in the same way that I would not care if a devoted vegan decided that he could not associate with people who use animal products. Why would I want to associate with someone who thinks I'm a bad person?

Trump got a higher percentage of the Black vote than any Republican since Gerald Ford. He nearly won an outright majority of Latino voters. How did a white supremacist candidate manage to do that? False consciousness? Marc Maron: "Progressives have really got to figure out how to deal with this buzzkill problem. You do realize we annoyed the average American into fascism."

Here's a subtle problem: An animation that looks "delightful" on the screens you have, might look pretty bad on a screen you don't have. For example, the author's animation for scaling a button looks fine on my M1 MacBook Pro, but jittery and sluggish on the crappy IBM ThinkVision monitor attached to my MacBook. See for yourself:

All of the examples in the article of “simplicity” involve the orchestration of complex platforms that are, for the most part, written using types. Try writing a browser that can pass Acid2 in Ruby and then try to convince anyone that what you’ve done is in any sense better than the Chromium codebase in all its complex glory.

Maybe the truth is that our job as developers is to manage the inherent complexity of the world we live in.

Looks like they've been doing a bad job.

They've created a pretty massive destabilization bust of the dollar, with a massive unrecovered crash since the inception of the fed [0].

Not long after the fed's inception, there was massive GDP destabilization[1], and then further boom-and-bust cycles.

Unemployment cycles circa before/after fed don't look terribly different either, especially if you exclude war time. In fact there was a pretty terrible boom-bust cycle about 20 years after the fed's inception. [2]

Which all does have me double checking all of this. We're getting long lag times, one giant bank bust in slow motion except distributed across all of us with USD going to zero, and even after the fed was created an awful great depression which some economists have theorized the fed even made worse.

Moving back to the response time -- it was a genuine question. I have no idea. Maybe the fed speeds up response by having an endless ability to quantitatively ease. Or maybe it acts like a big flywheel.

Continue to assign homework. Tie the homework to in class assessment such that if a student can do well on homework, without AI assistance, they are expected to do well on tests conducted in class, again without AI assistance.

Set homework grades to be a relatively small percentage of the final grade.

With the above framework, a student is incentivized to complete homework. If they cheat themselves and use AI, they'll do badly on the tests and badly in the class overall.

Tell the students about the above rationale. Tell them that they're not to use AI for homework, that you can't stop them from using AI, but that by using AI, all they get is a perfect score on homework and probably a bad overall grade.

I'm not specifically low-tech, but it's kind of what I'm ending up with.

I've always hated that people in sufficiently large groups seem to stop thinking for themselves. As soon as one starts doing something, people join in, just because.

I've sort of dealt with this fact by becoming suspicious of whatever the popular thing is at the moment. It makes me think twice about if I actually want something, or if I want it because it's new, flashy or popular.

I don't know if this qualifies as low-tech because I do have a desktop pc and an android phone. But I don't use streaming services, I don't listen to podcasts, i don't have any bluetooth-stuff, I only read physical books, I write using pen and paper, don't have a car, don't have any smarthome stuff, don't use social media, when I'm out of the house I don't have access to all my music, video's and holiday pictures, etc.

Honestly I don't feel like I miss out on anything.

To answer your 'How' question.. It helps me to imagine myself back in the 90s before I ever used the internet. Is a new tech/service/device something that I would have wanted or needed back then? Did I ever think "damn, I would love to be able to listen to my favorite radio show while walking the dog"? No? Well then the thing was never an issue for me, so I shouldn't try to fill that non-existent hole by listening to podcasts.

It literally styles itself as an encyclopedia, not a collection of summaries by "mainstream secondary sources".

https://en.wikipedia.org/wiki/Wikipedia:Five_pillars

> Wikipedia combines many features of general and specialized encyclopedias, almanacs, and gazetteers. Wikipedia is not a soapbox, an advertising platform, a social network, a vanity press, an experiment in anarchy or democracy, an indiscriminate collection of information, nor a web directory. It is not a dictionary, a newspaper, an instruction manual, nor a collection of source documents or media files, although some of its fellow Wikimedia projects are.

I think what we'll eventually see is frontier models getting priced dramatically more expensive (or rate limited), and more people getting pickier about what they send to frontier models vs cheaper, less powerful ones. This is already happening to some extent, with Opus being opt-in and much more restricted than Sonnet within Claude Code.

An unknown to me: are the less powerful models cheaper to serve, proportional to how much less capable they are than frontier models? One possible explanation for why e.g. OpenAI was eager to retire GPT 4 is that those older models are still money losers.

In our experience, the primary driver of Snowflake costs is not the compute for aggregation, but the compute required for lots of reads/scans.

We recently built a Snowflake-to-ClickHouse pipeline for a customer where aggregates are built hourly in Snowflake, then pushed into a ClickHouse table to power their user-facing dashboards.

By offloading dashboard queries to ClickHouse, they slashed their Snowflake bill by ~25%, which was worth millions to them.

(Admittedly, running aggregations elsewhere—for example, in Spark—could further reduce costs, but you would then need Iceberg to make the tables queryable in Snowflake.)

In relation to engine life there are several things that shorten life, most notably the EGR (Exhaust Gas Recirculation) introduces small particles into the engine that cause abrasion of the rings, pistons and cylinders among other parts. To compensate some people change their oil on very short intervals but that increases oil consumption. If I keep typing about emissions systems I will activate half of this site and people will scramble to find tailored statistics. I just operate on how often I have to replace things and this old fart has been able to keep old vehicles going for a very long time.

To block me in uBlock people can use this rule:

news.ycombinator.com##tr.athing.comtr:has(a.hnuser):has-text(/\bBender\b/)

The overall vehicle life is affected by other factors such as salt content on the road and in the air, quality of rubber gaskets and other components. To literally double the life requires regular special detailing and keeping rubber and plastic parts from drying out and salt from oxidizing the frame and body parts. Newer vehicles have special fasteners and fittings that have to be replaced with those that are serviceable and there are tricks to it one should learn from the old timer mechanics. Easy mode is to take a vehicle to a mod shop whilst it is still in good condition to be refurbished, stripped, coated, modified to better handle weather and driving conditions. Some modification shops can do this to classic vehicles for a big fee and then it can last 50+ years. One must be careful what they ask to be modded in some states.

I'm not sure why we've drifted talking about new lines/stations. Both Tube and BART hardly built anything in the last 10 years. I was only remarking on operating costs for what was already built by pandemic and the fact that ridership seems completely untangled from it.

It seems to me that BART management did what most of other government bureaucracies did around here during covid - threw their feet on the desk and took an extended 2+ year sabbatical

Presumably multi-causal (economic desperation, rising metal costs, perception that the crime won't be punished, getting the idea from others, etc.) but at least one component is probably the rise of high-powered, battery-operated tools. Battery tools are so much better today than they were even 10 years ago. In the picture from the article you can see the guy using a battery-powered reciprocating saw. Not long ago, an approach like that wouldn't have been feasible.

I think a lot of this is true, but not as critical as is being interpreted.

Compare the economics of purely cognitive AI to in-world robotics AI.

Pure cognitive: Massive scale systems for fast, frictionless and incredibly efficient cognitive system deployment and distribution of benefits are solved. On tap even. Cloud computing and the Internet.

What is the amortized cost per task? Almost nothing.

In-world: The cost of extracting raw resources, parts chain, material process chain, manufacturing, distributing, maintaining, etc.

Then what is the amortized cost per task, for one robot?

Several orders of magnitude more expensive, per task! There is no comparison.

Doing that profitably isn’t going to be the norm for many years.

At what price does a kitchen robot make sense? Not at $1,000,000. “Only $100,000?” “Only $25,000? “Only $10k”? Lower than that?

Compared to a Claude plan? That many people still turn down just to use free tier?

Long before general house helper robots makes any economic sense, we will have had walking talking, socializing, profitable-to-build sex robots at higher price points for price insensitive owners.

There are people who will pay high prices for that, when costs come down.

That will be the canary for general robotic servants or helpers.

The cost isn’t intelligence. There isn’t a particular challenge with in-world information processing and control. It’s the cost of the physical thing that processing happens in.

This is a purely economic problem. Not an AI problem at all.

I think the main fear is that these products will become so enshitified and engrained into everywhere that, looking back, we'll be wishing we didn't depend so much on the technology. For example, the Overton window around social media has shifted so much to the point that it's pretty normal to hear views that social media is a net negative to society and we'd be better off without it.

Obviously the goal of these companies is to generate as much profit as possible as soon as possible. They will turn the tables eventually. The asymmetry will go in the opposite direction, maybe to the extend that one takes advantage of the current asymmetry.

Author lists vulnerabilities of Docker, but it doesn't mean podman is more secure. Maybe it's more obscure so it is not as attractive for hackers as a target.

I tried to use podman, but that was largely a waste of time and I reverted to Docker. I don't have time going through docs to figure out why something that supposed to work is not working.

We sold badges at DEFCON31 that had a Morse code blinking option. Have to go back and look at the code to remember if it just flashed DEFCON or something else

We also had an option to connect up via serial and it would dump DEFCON or our team name at the terminal and we had games on the terminal. Amongst other things our badge did, it was a great value for $20

This seems like the kind of regulation that causes more harm than it saves in anyone's house actually burning down. I did a cursory search and didn't find any EU reports of a house fire caused by a L1 charger.

Sure you might burn a house down if you find one that has a plug which isn't correctly installed with loose connectors but the fire risk here wasn't the EV. Its the incorrectly installed wiring.

You don't tell people to get rid of their fridges because some people might have forgetten to plug theirs in and therefore they could get food poisoning from spoiled food inside.

>The sale qualifies only if:

>You buy the vehicle from a dealer.

This is such an annoying part of the tax incentive.

It's a huge, pointless gift to car dealers (who need no help) because it means they don't have to compete for price with private sellers or buyers. If I have a used EV to sell, I basically have to sell to the dealer because no buyer wants to bother buying from me when they can get the same thing from a dealer with a $4k tax credit on top.

The io_uring solution avoids this whole effort of mapping. It doesn't have to map the already-in-RAM pages at all. It reuses a small set of buffers. So there is a lot of random cache-miss prone work that mmap() has to do that the io_uring solution avoids. If mmap() does this in the background it would cache up with io_uring. I'd then have to get a couple more drives to get io_uring to catch up. With enough drives I'd bet they'd be closer than you think. I still think I could get the io_uring to be faster than the mmap() even if the count never faulted, mostly because the io_uring has a smaller TLB footprint and can fit in L3 cache. But it'd be tough.
Are LLMs better suited for PR reviews than full codebases?
by aaa_2006 | 2025-09-05 18:33:08+00:00
Semgrep recently published an analysis of how LLMs perform at spotting vulnerabilities in code: https://semgrep.dev/blog/2025/finding-vulnerabilities-in-modern-web-apps-using-claude-code-and-openai-codex/

I’ve been thinking about this problem and wanted to share a perspective.

When evaluating LLMs for static analysis, I see four main dimensions: accuracy, coverage, context size, and cost.

On accuracy and coverage, today’s LLMs feel nowhere close to replacing dedicated SAST tools on real-world codebases. They do better on isolated snippets or smaller repos, but once you introduce deep dependency chains, results drop off quickly.

Context size is another bottleneck. Feeding an LLM a repo with millions of lines creates huge problems for reasoning across files, and the runtime gets impractical.

That leads to cost. Running an LLM across a massive codebase can be significantly more expensive than traditional scanners, without obvious ROI.

Where they do shine is at smaller scales — reviewing PRs, surfacing potential issues in context, or even suggesting precise fixes when the input is well-scoped. That seems like the most practical application right now. Whether providers will invest in solving the big scaling problems is still an open question.

Curious how others here think about the trade-offs between LLM-based approaches and existing SAST tools.

sure. think original stuff. not another SaaS. but the biggest caveat is it's novelty cuz it's not a recognized idea in the main stream. But it will sure give you a piece of mind.

I just wonder what goes on a person's mind when they even considerer to buy a car from this guy.

The real problem that needs to be stopped is that other maker's have to buy "clean" credits from that company that is everything except clean.

This has to be stopped. And stop all credits and bonus for electric cars.

Electric cars can be a good thing, but not with amount of corruption. But we should focus on hybrid tech now, and not forget the conitnue to search for alternatives for petrol.

We do need some special tech to stop buy crude from this contries. But electric is not the one.

But hey, the amount of guys who really "believe" on electric cars on youtube (aka give-me-my-check-tesla) are too much.

My 2017 i3 REX is just fine. It needs new tires before winter hits, an alignment (it gets knocked way out really easily, especially if you've ever taken it on a less than perfect road. Washington State has many such roads), and I should probably proactively do an oil change on the REX. Oh, and drivers seat heater has a short so doesn't work (the fix from BMW would be prohibitively expensive, but I may try a DIY re-wire).

Otherwise, this car is as close to a perfect daily driver I've ever owned. I hope it lasts forever: not a single touchscreen, no OTA updates, decent battery range (and DC Fast Charging at 60kW+), gas engine to fall back on (with OBD-II programming you can enable Hold State of Charge on the NA models allowing you to truly treat the i3 as a proper series-hybrid and not just an emergency limp-along range extender that will crap out going up a hill in the cold), comfy seats, and did I mention NO TOUCHSCREENS and NO OTA UPDATES?

Android has really failed at this. Android apps are full of animations that serve no purpose or are even misleading, and slow down the experience. It's cargo cult copying from iOS. And the animations are janky, too.

Luckily Android has a developer option to double the speed of animations system-wide. It's the first thing I turn on every time I get a new phone. I find that double speed is about right. Designers tend to make every animation at least half as fast as it should be, to make sure you notice their effort.

I want a merge request with a short, meaningful comment and the diffs just like I’d get from a human. Then I want to be able to discuss the changes if they aren’t exactly what’s needed, just like with a human. I don’t want to have to hold its hand and I don’t want to have to pair program everything with a chatbot. It also needs to be able to show a logic diagram, a data flow diagram, and a dependency tree. If an agent can’t give me that, it’s not really ready to work as a developer for me.
