I suspect that LLVM is optimized for compiling with `-ftrapv`, perhaps for cheap sanitizing or maybe just due to design decisions like using unsigned integers everywhere (please correct me if I'm wrong). I'm personally interested in how RISC-V behaves on computational tasks where computing carry is a known bottleneck, like long addition. Maybe looking at libgmp could be interesting, though I suspect absolute numbers will not be meaningful, and there's no baseline to compare them to.

The Lords doesn’t actually have the power to veto bills thanks to the Parliament act. They also have a principle of ultimate legislative priority under which they defer to the commons in matters where the commons puts its foot down. They generally act as a revising body rather than outright attempting to defy the commons.

> Under the Parliament Acts 1911 and 1949 it is possible for a bill to be presented for Royal Assent without the agreement of the House of Lords, provided that certain conditions are met. This change was seen by some as a departure from Dicey’s notion of sovereignty conferred upon a tripartite body.

I would, I've written about this before. A common error is to think that say NSA mathematicians have access to what's in the "free world", but those on the outside don't have access to the inside.

The reason this is an error is because research is an interactive process. Spooks can read papers, but they can't freely discuss with outside researchers - not what they themselves are working on of course, but even talking to outsiders about what the outsiders are working on, can be risky, since it can accidentally reveal a lot.

Secrecy cripples research. Even in areas where the TLAs hoover up the majority of graduates (was apparently true of math a while ago), they often fall behind.

There was a time when the TLAs could just call people like Claude Shannon, demand he work for them and never tell anyone about what he was working on, and he would say OK. That time is long gone. They don't have that goodwill any longer, and the price of isolation for a researcher has only gotten worse as communication has improved.

Once the ballot is removed from the envelope, it is just a sheet of paper with votes on it. There's no name, serial number, or signature on it.

Hence "stuffing" in more ballots cannot be detected.

Printing the ballots on security paper will not eliminate this risk, but it will make it much harder.

I don't know if there is an auditable "chain of custody" of ballots from mailbox to the counting center. The fraud here would be "losing" ballots that are from precincts that tilt significantly in one direction or another.

That’s a life lesson worth learning, yes. Presentation matters, even if intent is genuinely positive, because patience is finite. Sometimes it will be awkward. If something gets flagged and it shouldn’t be, email the mods and ask if they would modify the flag so the comment remains visible. Learn, grow, try, fail, retry doesn’t work if you replace ‘try’ with ‘AI’.

As a non native speaker, I sometimes use LLMs to search for a way to formulate my thoughts like I intend them to be received by the reader. I'd never just copy the verbatim LLM output somewhere, it always sounds blunt and not like me, but I gladly apply grammar corrections or better phrasing.

I'd normally not do this for a text of this length, but just for fun, here's what ChatGPT suggests:

Nothing can't be first-class as long as it is not *directly* replacing the existing first-class citizens.

If Wasm modules can be loaded like this:

<wasm src="/module.wasm" start="main" data="..." />

...and if Wasm could access the DOM like this:

import dom, json, re, html, urllib.parse
from datetime import datetime

params = urllib.parse.urlencode({"category": "news", "limit": 10})
data = json.loads(await (await fetch(f"https://api.example.com/data?{params}")).string())
container = js.document.getElementById("app")
container.innerHTML = "".join(f"..." for i in data["items"])

...then developers would have jumped in right away.

I've found that many repair shops acknowledge the existence of two smartphone brands: Apple and Samsung. Bring anything else in and the most you get is a puzzled look.

Apple has the distinction of the iPhone being what everybody thinks of when they hear the word "smartphone". Everybody is familiar with it. That little xylophone jingle that serves as the iPhone's default ringtone plays in every detective show my wife watches on streaming, and everybody knows instantly what it means. That sort of ubiquity has network effects that you're not going to get with a Motorola, Sony Xperia, or even a Pixel. I've had to turn to Aliexpress to score a decent protective cover for my Pixel.

Introducing the new face of Code Debugging: GOL V1.1 pinpointed a (?:(?:\"|'|\]|\} signature—a literal needle in a haystack—that would have taken an hour of manual tracing.

In the new 'Face of Coding' era, we're not staring at screens anymore; we're orchestrating $1.2 surgical strikes on logic loops. Here is the diagnostic trace of the fix.

Error: (?:(?:\"|'|\]|\}|\\|\d|(?:nan|infinity|true|false|null|undefined|symbol|math)|\`|\-|\+)+[)];?((?:\s|-|~|!|{}|\|\||\+).(?:.=.)))

Output from the GOL V1.1 engine:

"Damn, okay... I see exactly what's going on here. It's frustrating, but the real reason this scan failed isn't some complex logic bomb; it's a simple, classic misunderstanding of regex performance. We're getting timed out by a classic Regular Expression Denial of Service (ReDoS). It's not a logic error, but an algorithmic inefficiency.
The problem is nested, unbounded quantifiers on overlapping matching groups. Our code, specifically .(?:.=.), creates an infinite nightmare for the backtracking engine. To find a potential match, the engine must explore every possible way to split any given string using those nested .* subpatterns. This means that for a string of length $n$, the number of paths to explore grows exponentially (something like $O(2^n)$ or $O(3^n)$). For small strings, it’s instant. For a string that almost matches but doesn't quite work, a modern regex engine could take hours to exhaustively test all potential combinations. The scanner, not being an infinite being, simply hits its wall and gives up (times out), which is why no patch is suggested—the engine didn't even finish evaluating the code.
To win next time, we must eliminate this specific structure. The correct approach is to recognize what we are actually trying to find. That .=. means we are looking for a variable assignment. The solution is to search specifically for identifiers (variable names) and assignment operators, not just any sequence of arbitrary text. We must specify exactly what is being assigned, how, and what type of value is expected, rather than letting the engine explore an exponentially large search space. We are trying to match a specific logical construct (assignment), not just any blob of text, and making that search pattern more precise is the only way to avoid the exponential backtracking."

Welcome to the new era. 2026.

Wait, are regular dashes not em-dashes now considered a sign of AI slop? I've been using dashes since forever.

~The comment you're replying to doesn't have any sentence of the form "X isn't Y, it's Z". It has "It's not X - it's Y".~ I see it now - it does have one "X isn't Y, it's Z" but that's hardly conclusive IMO.

While the comment does have "X but Y", it has a consistent mistake in punctuation - "X, but Y" would be the correct form, won't it? If an LLM produced this, I wouldn't expect the missing punctuation.

How does "fixing the symptom instead of the root cause" not make sense in the context of this discussion which is about coding agents producing marginal PRs.

I think a lot of even not very technical people have gotten used to TOTP QRCodes, and being able to store screenshots of them in password managers. (And having experience in losing 2FA keys that they'll go to some lengths to not repeat.)

I wonder if there's a decent way to encode these private keys in QRCodes? You can jam about 4kB in a high density one from memory? (I know that'd be possible from a developer/technical point of view, but if this were my project I'd want a talented UX designer to have complete authority over how this is presented and explained to users.)

One other idea - maybe implement a Shamir's Secret Sharing mechanism where your private keys get sharded and encrypted to a sufficient number of selected friends, so of you lose your s@ private key it can be re assembled by convincing - say - 8 out of 12 selected friends to give you their part?

Or alternatively - automate a "recovery mechanism" where you set up a new key pair and publish it on a temporary domain/site, and can then ask a friend/follower who can authenticate your identity out-of-band - to export all you posts decryptable with your new key, then put you new key and all your old posts back into your main site.

It helps but a LLM could still code a destructive command (like inlined python -c scripts) you can't parse by rules and regex, or a gatekeeper LLM be able to understand its implication reliably. My solution is sandbox + git, where the .git folder is write protected in the sandbox as well as any outside files being r/o too.

My personal anecdata is that both cases when Claude destroyed work it was data inside the project being worked on, and not matching any of the generic rules. Both could have been prevented by keeping git clean, which I didn't.

One suggestion from a fellow longwrite: Tweak that to “leave an opening for their optional reply” so that it’s okay if they don’t respond, so that you aren’t creating discomfort and pressure by the comment length, and you should see an easing both of pressure on yourself and on others. One of my most frequent longwrite sigs is “Reply optional as always” :)

Called the fire department's non-emergency line. Got a bot. The bot sent out someone who said the noise isn't a safety issue, and left.

Called the police department's non-emergency line. Got a bot that told me it's a civil problem and that there's nothing they can do.

Scouted out the fire department and chatted up the fire chief in person while he was walking back in after lunch. He was very concerned about all of this (finally, progress!) and called the management company while we stood there, but his call was answered by a bot that said someone would be out in less than 24 hours to silence the noise again.

Ironically, I read this article from start to finish, something that rarely happens with blog posts, which I usually abandon halfway through.

More seriously, I agree that writing short books or articles is an important skill. Writing long is easy; conveying the same amount of information concisely is much harder. It is also a sign of respect for busy readers.

I constantly find myself asking LLMs to be shorter, more direct, and more to the point, without fluff. They seem to have a tendency to generate endless streams of words.

Let's see, this is a great project, but the sandboxed virtual machine approach makes sense. I've had Claude Code destroy a configuration file on my local machine more than once, so running it remotely is actually smart, but I'm not sure.

However, when creating MCP tools, I've noticed that the processing isn't really what's expensive. It's when the agent gets stuck in a loop. For example, I note writes faulty code, executes it, detects the error, tries to "fix" it, makes it worse, rinses it, and repeats it 5 to 10 times. This quickly consumes the context window, regardless of where the code is running.

I'm curious: Does Oblien detect when an agent is simply wasting time? Or is that left to the agent framework? Because, I mean, sometimes I look for that solution and there isn't one :(

This aligns with something I've been noticing in practice: passing tests and being mergeable are fundamentally different quality bars. Tests verify behavior, but code review evaluates maintainability, readability, and whether the solution fits the broader architecture.

The SWE-bench metric essentially measures "can the AI produce a patch that makes tests pass" — which is closer to "junior developer who got the ticket done" than "experienced engineer who shipped clean code." The gap between those two is exactly where most code review friction lives.

What concerns me more is that as teams start using these benchmarks to evaluate AI coding tools, they might optimize for the wrong thing. A tool that produces mergeable PRs 40% of the time is arguably more valuable than one that passes tests 80% of the time but generates code that requires significant rework. We need benchmarks that capture the full review cycle, not just the CI pipeline.
Show HN: CmdRunner – Upload test cases and an AI agent runs them in a browser
by kiru-cmdrunner | 2026-03-12 05:51:00+00:00
I’m building CmdRunner, an AI agent that executes web application test cases directly from documents.

Most teams maintain Selenium or Playwright scripts, but many already have test steps written in Excel or documentation.

CmdRunner reads those steps and performs them in a browser like a human tester.

Workflow:
1. Upload test case file
2. Agent understands each step
3. Opens browser
4. Executes actions
5. Validates outcome
6. Generates report

Goal: reduce the time spent maintaining automation scripts.

If anyone is interested in trying it with real test cases, Register here:

I’m putting the current medical definition aside, we’ve been pushing the boundaries of what’s possible and who knows what the next centuries redefine. For the longest time in human history “clinical death” was almost always followed by permadeath.

As the person doing the dying you can’t rationalize it as “no worries, it’s just clinical, I’ll be back”. You die, it’s light out, later on you recover and are told “you were clinically dead”. You experienced death for all intents and purposes because I don’t think there’s a cognitive process that allows you to differentiate the stages. Heck, deep sleep might be how death “feels” like.

Do people fear death (excluding suffering) because of the threshold itself or the FOMO? Missing on what would come next?

There's 8 Mac configurations for the Neo alone (4 colors by 2 storage options).

The Air has 24234 (maybe not precisely, I'm not going to go through all the permutations) = 192 configurations.

I'm not going to try to go through the MBP, Studio, or Pro, but realistically you're looking at a few thousand configurations, not 30.

There's an asymmetry here that bothers me. Companies increasingly use AI to screen candidates (resume parsing, AI interviews, automated rejections), but if a candidate uses AI to help write their resume or prepare answers, it's considered dishonest.

The deeper issue is what this signals about how the company values the relationship. An interview is supposed to be bidirectional — the candidate is also evaluating the company. When you replace that with an AI bot, you're essentially saying "we'll evaluate you, but we won't give you the opportunity to evaluate us." That's a red flag regardless of the technology involved.

That said, I can see a narrow use case where AI pre-screening might actually be more fair than human screening — removing unconscious bias from initial rounds, standardizing questions, giving every candidate the same amount of time. The problem is when it's used to scale rejection rather than to improve the process for candidates.

It's less like having the house taken away, and more like having your house's street address reassigned to someone else's house. Sure, you still own the land. Your deed gives you ownership of parcel #530453080, not of the identifier "123 Vine Street", so nothing you legally own has been taken from you.

But it's your identity. It's the way you've been putting yourself into the world and telling people they can reach you there. It used to be that if someone sent a message to that address, or tried to navigate to that address, they would reach you; but now, they'll be taken to somewhere else, and they perhaps won't even realize what's happened.

And for the ownership issue, sheesh. Yes X, in a literal sense, owns all the usernames. We're talking about whether it's morally right for them to do, not about whether it's illegal. If they had held back these short "valuable" usernames from the beginning, no one would care; it's the act of taking away someone's established identity that is problematic.

I can think of at least a couple of dozen fairly technical friends who'd be capable enough to set this up themselves, and who're at least adjacently interested in recreational paranoia. And probably another dozen or two who're definitely into recreational (or possibly delusional and/or fully deserved paranoia) who'd be willing to learn or get help setting this up.

Right now, those circles of friends are _reasonable_ well served with some combination of Mastodon (effectively zero security but with decent findability) and Signal (much more limited mostly to only people you'd be OK with having your phone number).

I will definitely take this for a spin, and start having discussions with particular groups of friends to see it I get any traction.

> I immediately stopped considering them as options. If you can’t be bothered to have a human respond to my email when I’m trying to give you my money, what level of service can I expect once I’m already obligated to pay rent?

I will go out on a limb and suggest that they are probably happy that you’ve self-selected out of the process.

I’m not saying your expectations are unreasonable, but you have higher expectations than most consumers, and that ultimately becomes a pain in their ass.

Never been a fan of Pogue's 'pop tech' take on things, but GREAT interviews here with Woz, Bill Fernandez, Ron Wayne, Chris Espinoza, John Sculley(!), Robert Brunner, Avi Tevanian, and John Rubenstein - never going to see a team like this again. Also good to hear names like Burrell Smith, Joswiak, Jef Raskin, and Andy Hertzfeld throughout. I miss Steve Jobs, but I don't wish he was still with us - he went out on top, and I'm sure the current landscape would have relegated him to outcast status yet again.

Growing up across the bay in the 80s during Apple's heyday makes me so very nostalgic for the culture of innovation, creativity, and fun that once made us elementary school nerds excited about building great things and outshining other nerds, with our unsung heroes not too far from us geographically. Also, the massive pranks at Sun and SGI just made everyone believe they can be a kid well past their teens. Now I'm seeing the high school and college kids I coach are so obsessed with scale, clout, and unbridled control, through hedged iterative development efforts and overhyped marketing. Grit's been replaced by grift.

For me, the final nail in Silicon Valley's coffin was when Weird Stuff closed. Glad to have CHM continuing to carry the torch with amazing retrospectives like this.

I've been doing exactly this for the past few weeks, really. Claude Code + MCP plugins is the setup that really worked for me.

The key thing I learned was not to just tell Claude your repository and hope for the best. The raw approach consumes tokens incredibly fast, but Claude reads entire files when it only needs one feature, retries incorrect edits more than 5 times, and loses context halfway through.

What really works is giving Claude a CLAUDE.md file in the root of your repository with specific instructions for the workflow (which tools to prefer, when to compress or read raw, etc.). Claude Code reads it automatically upon login. Think of it as an .editorconfig file, but for AI behavior.

For the $25/PR review use case specifically, the bottleneck isn't Claude's intelligence, but the context window management. A repository of 500 files can exhaust the window before Claude finishes reviewing. You would need some kind of indexing layer that provides Claude only with the relevant snippets for each PR difference, not the entire codebase.

What kind of repositories do you have in mind? The approach varies greatly depending on the size, but I'd like to hear your thoughts.

The post mentions the deficiencies of TCP for mobile devices over unreliable links, but I've had nothing but trouble with Wireguard when connecting from phones via mobile data.

I suspect it's due to my mobile operator doing traffic shaping / QoS that deprioritizes UDP VPN.

In contrast, connecting to OpenVPN over TCP was a huge improvement. Not at all what I expected.
