I designed highways. This is correct, and this is why weight restrictions exist. Noncompliance is not that much of an issue, and there are occasional permitted loads anyway when there’s a need to haul industrial equipment or unusually large objects.

The most important thing to remember about flexible, pavement lifespan is that asphaltic pavements are not designed to last forever. The asphalt binder will eventually oxidize and become brittle even with no traffic. These surfaces are meant to be consumable bearing services that last for 10 or 20 years and then have to be removed and or overlaid.

What's a decent time for this?

I was curious what it would take if I approached it the way I do with most CSV transformation tasks that I'm only intending to do once: use Unix command line tools such as cut, sed, sort, and uniq to do the bulk of the work, and then do something in whatever scripting language seems appropriate to put the final output in whatever format is needed.

The first part, using this command [1], produces output lines that look like this:

219,/blog/php-81-before-and-after,2021-06-21

and is sorted by URL path and then date.

With 1 million lines that took 9 or 10 seconds (M2 Max Mac Studio). But with 100 million it took 1220 seconds, virtually all of which was sorting.

Turning that into JSON via a shell script [2] was about 15 seconds. (That script is 44% longer than it would have been had JSON allowed a comma after the last element of an array).

So basically 22 minutes. The sorting is the killer with this type of approach, because the input is 7 GB. The output is only 13 MB and the are under 300 pages and the largest page count is under 1000 so building the output up in memory as the unsorted input is scanned and then sorting it would clearly by way way faster.

[1] cut -d / -f 4- | sed -e 's/T..............$//' | sort | uniq -c |
sed -e 's/^ *//' -e 's/ /,\//'

#!/bin/zsh
echo "{"
PAGE=none
while read LINE; do
COLS=("${(@s/,/)LINE}")
COUNT=${COLS[1]}

I've been thinking recently about how with the impending demographics crunch hitting a lot of countries soonish you're going to see a sort of day of reckoning for municipalities that were run poorly in the past because people will just move to ones that that don't have horrible budget and infrastructure deficits and the one sthat do will just shrivel up and die.

Tha perpetually increasing population growth is no more and that means no more growing tax base to paper over terrible decisions to pass them onto another generation.

For the first time in a long while we're looking at actual, real selection pressures on municiptalities.

If that were true, news organizations wouldn't be as careful as they are to preface the word "alleged" before the behavior -- before or after a trial. I don't think you'll find any reputable commercial newsgathering organization that makes a plain statement that Kyle Rittenhouse is a murderer.

The First Amendment doesn't protect the speaker against all forms of defamation (though it does put some barriers up that make it harder to win in some circumstances). If it did, defamation as a cause of action wouldn't exist at all.

As a practical matter, though, this is largely theoretical. Once you've been through the rigamarole of arrest, prosecution, and trial, even if you're found not guilty of the crimes committed, the reputational damage is just too widespread. You're not going to go after the defamers: there are just too many, and if you tried, there would be a fair question as to whether you have any positive reputation left to injure. Your life is pretty much ruined. It's a pretty terrible situation for the wrongly accused.

Yes I agree, but the problem I'm pointing out is that in a phrase as simple as "X person sucks" your system flagged one as implicitly racist because the person being criticized was black.

Nothing in "Obama sucks" implied any kind of racism. If it's so baked in that with a simple phrase like that it reaches for dogwhistles, how can anyone trust the objectivity of this?

It's a chicken and egg problem. The way to make buses competitive is to build bus only lanes. But to do that you end up removing a lane for drivers and dedicating enforcement resources to keeping bus lanes free of private vehicle traffic.

The usual pattern is when a bus only lane is proposed, drivers complain because they view the bus as a social program. Local legislators often take the drivers' side because they also view the bus as a social program. Even if you get the political capital to push a bus only lane, traffic enforcement will routinely ignore bus lane violations. LA is making waves on the latter problem by attaching cameras to buses which automatically write tickets for cars blocking the bus lane.

Ultimately it's a politics problem. If nobody wants to spend political capital on running a bus system as a transport program, it ends up as a social program.
by righthand | 2026-02-25 22:05:46+00:00
Just want to mention that the type of bus I'm referring to is the local municipal bus system in Colorado not Greyhound-type national bus lines. The national bus lines like Greyhound are indeed in disrepair, even in Nyc the bus stop is essentially the parking lot you leave from. It can be 100F or 0F and if you get a delay it's miserable. The main difference being the local municipal system is under utilized and the private corporation system is probably squeezing pennies for service.

so the story is about a silly law requiring bike lanes and handicap curbs and your proposal is to kick everyone out of their homes and remigrate them into the cities?

ADA code is insanely expensive. We did a couple blocks of those silly dimple ramps for $250,000 . You could hire every blind person in town a personal guide for less than it would be to ADA all the side walks.

Fascinating. I've read 5 posts about this and they're all either "anthropic is dropping their ethics" or "anthropic is fighting the facists" - and whether due to echo chamber or other perhaps more nefarious dealings (some of which I cannot posit due to forum rules) the posts below all of them are more or less in accord with one another which is a rarity for political discourse on HN.

I built a tiny Notepad clone in ~5 minutes using an LLM: open/save, plain text, no surprises.

Lately I've been doing the same for other small utilities. Roughly half the little tools I use are ones I generated and kept because they’re predictable and easy to audit.

The point isn't replacing built-ins; it's reducing dependence on shifting defaults. I want to care less about what the software/os vendor changes this time.

Sonder (noun). The profound feeling of realizing that each random passerby is living a life as vivid and complex as your own. Every passing car is being driven by another human being with a brain, thoughts, feelings, relationships, things they like and things they don't like. Every apartment window on a giant skyscraper is the little corner of the world that a person calls home. Everyone in their own way is a main character in their life.

Lifespan bridges that gap between everyone else in the world and you by letting you experience life through someone else's perspective. Create your own character or let the algorithm pick for you and read through a spirited journey of their life. Get married, join the military, start a business, the world is your oyster with Lifespan. What choices are you going to make?

This has little to do with EVs, and much more to do with the idea that whoever brings a heavier vehicle to collision, wins (and lives). Hence the propensity to drive truck-sized SUVs and actual F-150s with just the driver, and the light load, but the pleasant feeling of safety. Who's gonna survive in an incident of road rage gone bad, a Ford Explorer or a Fiat 500?

Coming back to the EVs, a small EV is a possibility, because it takes less power to move a lighter and smaller car. But would it sell on the US market?

Author here. We often hear that 95% of enterprise AI pilots fail. But the real friction in large organizations isn't the 95% that fail—it's the 5% that actually work, which the institutional immune system then actively tries to kill.

In this piece, I look at the recent $300B SaaS wipeout and argue that the market is finally pricing in a brutal divide: companies selling "surplus" (staff aug, API wrappers) vs. companies selling "scarcity" (liability shields, deep workflow integration).

The core thesis: Generative AI killed the IT "Dark Room." Failures are now instantly visible to the board, benchmarked against a $20 ChatGPT subscription. Because of this transparency, what enterprises are actually buying when they sign a $5M contract isn't better technology than a $50k pilot. They are buying a legal and political liability shield.

To map this, I propose shifting from the traditional tech stack to a margin-based "Value Stack" (Infrastructure > Runtime > Governance > Workflow), where Governance functions as an independent, highly profitable economic layer.

Curious if folks building B2B AI tools here are experiencing this friction between selling pure tech (surplus) vs. selling operational accountability (scarcity).

They get the privilege of immediately polluting the website with LLM-generated comments.

Many of them sound and look completely normal and have others on here interacting with them. They don't use em dashes, sometimes they'll use all lowercase text, sometimes the owner of the bot will come out and start commenting to throw you off.

All examples I've witnessed here.

HN should immediately start implementing at least some basic bot detection methods without requiring us to email them every time. I've discovered multiple bots make detailed comments within 30 seconds of each other in different threads, something a normal human wouldn't be able to do. That should be at least flagging the account for review. Obviously they'll get smarter and not do that soon but it would help in the short term.

I'd say it's not an issue but everything I described above has happened in less than a month and every day now I'm discovering bots here.

Yes, it's glaringly obvious to me that they've been actively suppressing their own tech sector. Feels like a lot of EU politicians owned shares of US tech companies.

This effect of politicians making decisions based on what corporate shares they own is ubiquitous now.

In the other direction, I even wonder if US threats about Greenland were related to this trend of Denmark moving off US big tech. I feel like the real game is military coercion dressed up as economics.

I suspect if people knew the real reasons behind each political decision, they'd be shocked. I'm sure it's all 100% about money; about taking as much as possible whilst giving as little in exchange as possible; filling the gap with pure coercion.

You are incorrectly assuming the Esclade isn't on 32+" tires with 285+mm width and the Wagoneer isn't on pizza cutters. Tire size has increased greatly on SUV and light trucks, which exerts less ground pressure.

It's not realistic to do this on a heavy truck, which run 110+ PSI on heavy wall tires and why they cause the power law damage to roads.

So I was about ready to rant about bloat in modern software, but I checked first: the new edit.exe for Windows is 260kB. The old editor for DOS 6.22 was actually provided by qbasic.exe, which had the editor and a full BASIC interpreter packed in 250kB. Edit.com was just a tiny wrapper.

This isn't bad at all given how most other software evolved in thr the intervening 30 years.

I wrote this because I was fascinated by the gap between an LLM's ability to talk about chess and yet and consistently make legal moves.
Even with huge context windows and massive training sets, LLMs consistently fail at basic chess logic once they are taken "out of book." In the post, I break down why this isn't just a matter of more data, but a fundamental mismatch between transformer architecture (probabilistic token prediction) and the symbolic, state-based requirements of a 64-square grid.
Show HN: AgentMD – CI/CD for AI agents, makes AGENTS.md executable
by iedayan03 | 2026-02-25 22:09:01+00:00
AgentMD parses, validates, and executes AGENTS.md files—the standard used by 60k+ repos for AI coding tools (Cursor, Codex, etc.). Instead of just reading the spec for context, we run the build, test, and lint commands it describes—with guardrails and governance built in.

What we do:
• Parse & validate AGENTS.md (YAML frontmatter, sections, commands)
• Execute with sandboxing (blocks dangerous patterns by default)
• Dashboard: execution history, success rates, ROI metrics
• GitHub App, Slack approvals, human-in-the-loop for sensitive ops

Try it live: https://agentmd.vercel.app — paste your AGENTS.md, get your score. CLI and GitHub Action available from source.

Open source core (MIT), cloud dashboard for teams. Would love feedback from anyone using agentic coding tools.

I'm arguing that a curation process that includes security review is likely to produce a more secure set of software. Admittedly it might be completely ineffective, but I think that's an unreasonable assumption. So some review is more secure than no review. Now I'm not saying "better", you could argue it's a false sense of security, but it's still more security.

Thanks for reading! Your current method, pushing the load until the GC spirals and then comparing the CPU utilization, is exactly the painful, trial-and-error approach I'm hoping this new API helps alleviate.

You've hit on the exact next frontier of GC observability. The API in JDK 26 tracks the explicit GC cost (the work done by the actual GC threads). Tracking the implicit costs, like the overhead of ZGC's load barriers or G1's write barriers executing directly inside your application threads, along with the cache eviction penalties, is essentially the holy grail of GC telemetry.

I have spent a lot of time thinking about how to isolate those costs as part of my research. The challenge is that instrumenting those barrier events in a production VM without destroying application throughput (and creating observer effects) is incredibly difficult. It is absolutely an area of future research I am actively thinking about, but there isn't a silver bullet for it in standard HotSpot just yet.

Something that you could look at there are some support to analyze with regards to thread pauses is time to safepoint.

Regarding OpenTelemetry. MemoryMXBean.getTotalGcCpuTime() is exposed via the standard Java Management API, so it should be able to hook into this.

> Isn't Nagle usually introduced in a networking class typically taken by CS (non-CE/EE) undergrads

Networking, OS, and Distributed Systems is increasingly treated as CompE or even EE nowadays in the US.

> Just because EEs are exposed...

That's the thing - I truly do not believe that EE and CS should be decoupled, and I believe ECE as a stopgap is doing a disservice to the talent pipeline we need for my verticals to remain in the US, especially when comparing target American CS and EECS programs to peer CEE, Indian, and Israeli CS programs [0].

There is no reason that a CS major should not be required to take a summary circuits, DSP, computer architecture, and OS fundamentals course when this is the norm in most CS programs abroad. Additionally, I do not see any reason for EEs and ECEs to not take Algorithms, Data Structures, and Compilers as well.

> Just because EEs are exposed to some mathematical concepts during their training doesn't mean that non-EEs are not exposed through a different path

Mind you, I'm primarily in Cybersecurity, AI/ML infra, DefenseTech, and DeepTech adjacent spaces - basically, anything aligned with the "American Dynamism" or Cyberstarts thesis.

From what I've seen, the most successful founders are those who are able to adeptly reason and problem solve, but are also able to communicate to technical buyers because you are selling a technical product where those people make the decision.

Just because an approach isn't useful today doesn't necessarily imply it isn't in the future and being exposed to those kinds of knowledge and foundational principles makes it easier for one to evaluate and reason through problem spaces that are similar but not necessarily the same - for example, going to the Nagle's example - this was a bog standard networking concept that has now become critical in foundation model training because interconnect performance is a critical problem which can impact margins.

A lot of foundational knowledge is useful no matter what, and is why we fund founders and hire talent at competitive salaries.

I suspect you don't understand how serious the problem is. The problem isn't "we need to add bike lanes." The problem is that the streets have to be repaved anyway and if the city can't afford to simply bring them up to code in the short run, then they can't afford to keep repaving them at all in the long run.

The sidewalks are going to have to be completely replaced eventually... not just the sections that need ramps. Right now the city can't afford to replaces just the ramp sections.

Cutting taxes has consequences.
Americans have enjoyed a huge increase to their living standards over the years and have become decoupled from many of the services that their taxes fund. In turn, large swaths of the populace are insulated from the consequences of degrading government services and infrastructure. This has caused a shift in attitudes towards taxes as most of these Americans no longer see the benefit of paying their taxes, incentivizing politicians to focus on cost reduction and tax breaks.
The problem here is that this attitude of Anti-Taxation has translated into no longer addressing the root cause, and people believing things like unproven stories of government corruption as being the sole cause of these degrading services despite the evidence for such being low to non-existant.
They dont want to address the real cause, so look to a convenient scapegoat that explains the degredation without accepting that they should pay more taxes.

Just like how at the federal level DOGE found almost no waste and corruption during their crusade against the federal services (stoked by similar anti-tax sentiment) it seems that every time a narrative of "corruption" takes hold enough to actually tackle the issue and launch a program to handle it, the program in turn finds its just wasting money.

People just need to accept paying more taxes in order for their society to flourish.

Hi all, author here. Please don't go to this website. It's expensive for me. It's a realtime multiplayer text-to-website chat, powered by Sonnet 4.6, that I built to showcase the incredible agency and speed frontier models have attained. I am paying API costs out-of pocket. Call it a business expense?

It's inspired by Pieter Levels' tweet about chatting with his websites. [1]

It uses the same tool under the hood as the core web offering, bareclaw [2], a thin Claude Code CLI wrapper I created to enable custom CC client creation while leveraging your Claude Max subscription.

Hi,
I sort of wandered into my career. I started in telecom due to a co-op, and then jumped to a cool job making computers for blind people that was both closer to my home, but also offered the opportunity to see many parts of the business. I ended up working on electronics and software in the medical device field. If one has the aptitude for it, I think jobs that are closer to the hardware will have a much longer shelf life. Get a copy of "Horowitz and hill", if you find that book entertaining, you should be fine.

I feel like the synthesizer--CMI Fairlight, Moog anything, Synclavier, PPG Wave, and just the general concept of modular synthesis--are pretty staunch competitors. Yours is certainly a fun and fair take, and arguably the electric guitar+tube amps birthed so many genres (blues, soul, funk, rock, punk, metal, etc) where as synthesizers remained pretty niche with their contribution to experimental music and pop music, mixing in with rock funk and disco, and the titan of EDM that grew out of that.
