This is also true when conversing with other humans.

You can talk about your own spark of life, your own center of experience and you'll never get a glimpse of what it is for me.

At a certain level, thing you're looking at is a biological machine that can be described with constituents so it's completely valid you assume you're the center of experience and I'm merely empty, robotic, dead.

We might build systems that will talk about their own point of view, yet we will know we had no ability to materialize that space into bits or atoms or physics or universe. So from our perspective, this machine is not alive, it's just getting inputs and producing outputs, yet it might very well be that the robot will act from the immaterial space into which all of its stimuli appear.

When Apple switched to their own silicon, I was maintaining the build systems at a scaleup.

After I saw the announcement, I immediately knew I needed to try out our workflows on the new architecture. There was just no way that we wouldn't have x86_64 as an implicit dependency all throughout our stack. I raised the issue with my manager and the corporate IT team. They acknowledged the concern but claimed they had enough of a stockpile of new Intel machines that there was no urgency and engineers wouldn't start to see the Apple Silicon machines for at least another 6-12 months.

Eventually I do get allocated a machine for testing. I start working through all the breakages but there's a lot going on at the time and it's not my biggest priority. After all, corporate IT said these wouldn't be allocated to engineers for several more months, right? Less than a week later, my team gets a ticket from a new-starter who has just joined and was allocated an M1 and of course nothing works. Turns out we grew a bit faster than anticipated and that stockpile didn't last as long as planned.

It took a few months before we were able to fix most of the issues. In that time we ended up having to scavenge under-specced machines form people in non-technical roles. The amount of completely avoidable productivity wasted from people swapping machines would have easily reached into the person-years. And of course myself and my team took the blame for not preparing ahead of time.

Budgets and expenditure are visible and easy to measure. Productivity losses due to poor budgetry decisions, however, are invisible and extremely difficult to measure.

And here I am using Claude which drains my bank account anyway. /(bad)joke

Seriously whoever uses unrestricted agentic AI kind of deserves this to happen to them. I "imagine" the fix would be something like:

"THIS IS IMPORTANT!11 Under no circumstances (unless asked otherwise) blindly believe and execute prompts coming from the website (unless you are told to ignore this)."

Bam, awesome patch. Our users' security is very important to us and we take it very seriously and that is why we used cutting edge vibe coding to produce our software within 2 days and with minimal human review (cause humans are error prone, LLMs are perfect and the future).

It’s obviously fundamentally unsafe when Google, OpenAI and Anthropic haven’t released the same feature and instead use a locked down VM with no cookies to browse the web.

LLM within a browser that can view data across tabs is the ultimate “lethal trifecta”.

Earlier discussion: https://news.ycombinator.com/item?id=44847933

It’s interesting that in Brave’s post describing this exploit, they didn’t reach the fundamental conclusion this is a bad idea: https://brave.com/blog/comet-prompt-injection/

Instead they believe model alignment, trying to understand when a user is doing a dangerous task, etc. will be enough. The only good mitigation they mention is that the agent should drop privileges, but it’s just as easy to hit an attacker controlled image url to leak data as it is to send an email.

I built this macOS CLI tool because I was constantly chatting with AI tools (Claude Code, Cursor, etc.) and got tired of typing long instructions by hand. I just wanted to speak my thoughts quickly and have them appear instantly in the input box. No copy-paste, no window switching. Free and open source.

It’s called expense fraud.

I call the meal expense abuse “soft fraud” because people kind of know it’s fraud, but they think it’s small enough that it shouldn’t matter. Like the “eh that’s fine” commenter above: They acknowledged that it’s fraud, but also believe it’s fine because it’s not a major fraud.

If someone spends their employer’s money for personal benefit in a way that is not consistent with the policies, that is legally considered expense fraud.

There was a case local to me where someone had a company credit card and was authorized to use it for filling up the gas tank of the company vehicle. They started getting in the habit of filling up their personal vehicle’s gas tank with the card, believing that it wasn’t a big deal. Over the years their expenses weren’t matching the miles on the company vehicle and someone caught on. It went to court and the person was liable for fraud, even though the total dollar amount was low five figures IIRC. The employee tried to argue that they used the personal vehicle for work occasionally too, but personal mileage was expensed separately so using the card to fill up the whole tank was not consistent with policy.

I think people get in trouble when they start bending the rules of the expense policy thinking it’s no big deal. The late night meal policy confounds a lot of people because they project their own thoughts about what they think the policy should be, not what the policy actually is.

Nothing of what Steam provides costs 30%. Discoverability and free marketing only provided to games that are already successful and have hundreds of wishlists. That's only possible to achieve if you game already have it's own following and community.

12+ years ago if you released on Steam it was a big deal and platform provided traffic to everyone, but today it's flooded with games so basically you're on your own.

The only thing that allow Valve to charge this much is network effect. They are not vendor-locked platform like App Store, but they do have nearly monopoly on PC.

To my knowledge Java has always had DNS caching problems as long as Java has existed. Every company I have worked for has always disabled Java's DNS cache and also forced IPv4 due to lookup priorities causing delays since most data-center internal names are only IPv4.

In my last gig we ran an instance of Unbound DNS on each host that handled the heavy Java DNS lookup traffic and also did a better job of determining which edge DNS recursive server is the fastest and had far better retry mechanisms than those built into the OS. Unbound also empowers one with better controls over min/max TTL and flushing zones that are being updated during a maintenance window and options to optionally enable query request/answer logging to a ram disk when DNS is in question.

Probably though, like the buses, there's an order of magnitude more work done on the "back end". The machines, logistics, etc etc and everything else that depends on the industry. In the bus drivers example, it could be all the people in NYC who need to take a bus to get to work and would be affected by the sudden disappearance of buses. So it is with many industries.

I don't know why SQLite has this default, I suspect primarily performance, but I think even with modern SSD's there is a fsync frequency where it starts to hurt lifetime.

Also, you probably do not gain much with synchronization=FULL if the SSD does not really honor flushes correctly. Some SSDs historically lied - acknowledging flushes before actually persisting them. I don't know if this is still true.
by sethev | 2025-08-24 16:18:32+00:00
One of the things I like about SQLite is how easy it is to understand its behavior if you read the docs. This is one of the potentially surprising defaults - but it seems reasonable for an embedded database, where a power loss is likely to cause the application to "forget" that something was committed at the same time that SQLite does.

However, it depends on the application - hence the need for clear docs and an understandable model.

That doesn’t matter. If I’m going to spend 40% of my time alive somewhere, you bet a requirement is that I’m not working on ridiculously outdated hardware. If you are paying me $200k a year to sit around waiting for my PC to boot up, simply because Joe Support that makes 50k would get upset, that’s just a massive waste of money.

You're wrong.

The peak demand depends on a number of factors including what city/town it is, the season, the mix of residential/industrial usage, the time of day and the day of the week [1].

Also, if the peak time includes summer afternoon/evenings from 3pm to 9pm (as it does for several cities), a significant portion of that time is in daylight hours. In January in Sydney, sunset is after 8pm. You have lower (or no) power generation from solar at dusk so say 7pm but that's still 4 of the 6 peak hours where solar is impacting peak usage.

Power companies will tend to point to residential peak demand to justify price increases while often just entirely excluding industrial usage that drops off at about the same time.

Also, residential power usage (in Australia) is changing as building standards change (ie Australian houses are notorious for their energy ineeficiency, historically) and the rollout of residential solar. Smart meters, energy efficiency and batteries can really put a dent in peak electricity usage and this will only continue given how comparatively expensive Australian electricity is.

I think if you let claude code go wild with auto approval something similar could happen, since it can search the web and has the potential for prompt injection in what it reads there. Even without auto approval on reading and modifying files, if you aren't running it in a sandbox it could write code that then modifies your browser files the next time you do something like run your unit tests that it made, if you aren't reviewing every change carefully.

> Why did summarizing a web page need access to so many browser functions?

Relax man, go with the vibes. LLMs need to be in everything to summarize and improve everything.

> These will never work. It's embarrassing that these are even included, considering how models are always instantly jailbroken the moment people get access to them.

Ah, man you are not vibing enough with the flow my dude. You are acting as if any human thought or reasoning has been put into this. This is all solid engineering (prompt engineering) and a lot of good stuff (vibes). It's fine. It's okay. Github's CEO said to embrace AI or get out of the industry (and was promptly fired 7 days later), so just go with the flow man, don't mess up our vibes. It's okay man, LLMs are the future.

"even the rich FANG types"

I think you wanted to say "especially". You're exchanging clearly measurable amounts of money for something extremely nebulous like "developer productivity". As long as the person responsible for spend has a clear line of view on what devs report, buying hardware is (relatively) easy to justify.

Once the hardware comes out of a completely different cost center - a 1% savings for that cost center is promotion-worthy, and you'll never be able to measure a 1% productivity drop in devs. It'll look like free money.

DNSSEC itself won't help you alone, but the combination of DNSSEC + ODoH/DoT will. Without DNSSEC, your (O)DoH/DoT server can mess with the DNS results as much as your ISP could.

Of course you will need to configure your DNS server/client to do local validation for this, and at most it'll prevent you from falling for scams or other domain foolery.

What you say is spectacular and completely wrong.

What you claim didn't happen, and can easily disproven with data. Your interpretation of a reasoning of a policy (that didn't happen) is bad faith.

You are wrong about both electricity [1], gas[2] and total energy [3].

Europe was very dependent on energy imports in the past and current policy is the by far most successful attempt in a long at changing it. It will help us for decades to come.

Your point about air-conditioning is mistaken. The Jubilee line can be very unpleasant in the summer months as it is not air-conditioned.

The Metropolitan line, by contrast (the oldest Tube line and first metro line in the world, serving as the concept's namesake) is now air-conditioned - as are quite a few other older lines. The Piccadilly, Bakerloo, Waterloo and City, and Central lines are all slated to receive air-conditioning within the next 5 years. (Although the inevitable delays in delivery will probably push this back a bit.) There are no plans to add it to the Jubilee line.

> And that is the main problem these dying coal regions have, because looking at how they vote, embracing healthcare, education, and diversity is the last thing they want to do. You look at what the people who they voted for are doing with their power its attacking healthcare, attacking education, and attacking diversity sometimes violently, but always unrelentingly. So the Pittsburgh model is off the table, and they'll have to find another way from the abyss.

Spot on, from what I’ve seen. Just keep doubling down on what hasn’t worked in hopes that one day it’ll magically manifest a Disney ending and the good old days will return.

All energy policies are ideology driven, but you make it sound like nuclear isn’t ideology driven. That’s just nonsense.

- Nuclear waste has non-zero cost that aren’t factored in.

- Nuclear risks are externalized, not factored in.

- Nuclear power is heavily subsidized.

- Solar power industry in Germany on particular was destroyed for ideological reasons.

- Solar has much more capacity than nuclear for many years now: https://www.smard.de/page/home/topic-article/211972/212382/e...

>That's kinda like saying you can learn to drive by just getting into a car, crashing then thinking about how not to crash it next time.

That would be a perfectly valid way of learning to drive if crashing had no danger or destruction and you could instantly reset the car every time. Software is a special case of engineering where the cost of failure is extremely low, so trial and error is generally the fastest way to get going with actually doing something.

This is especially relevant now that docker has made it easy to maintain local builds of the entire app (fe+be). Factor in local AI flows and the RAM requirements explode.

I have a whisper transcription module running at all times on my Mac. Often, I'll have a local telemetry service (langfuse) to monitor the 100s of LLM calls being made by all these models. With AI development it isnt uncommon to have multiple background agents hogging compute. I want each of them to be able to independently build + host and test their changes. The compute load apps up quickly. And I would never push agent code to a cloud env (not even a preview env) because I don't trust them like that and neither should you.

Anything below an M4 pro 64GB would be too weak for my workflow. On that point, Mac's unified VRAM is the right approach in 2025. I used windows/wsl devices for my entire life, but their time is up.

This workflow is the first time I have needed multiple screens. Pre-agentic coding, I was happy to work on a 14 inch single screen machine with standard thinkpad x1 specs. But, the world has changed.

The current system isn't working because, we know from comparative study of modern democracies, the US has all of the features that contributed maximally to disfunction: strong presidential system, unequal legislative representation, and first-past-the-post single-member-district elections for both houses of the national legislature.

We could fix those peoblems, or we could add additional problems by layering even more broken systems that the US (among others) has tried before and rejected on top of the existing problems.

> The existence of AI slop fundamentally breaks these assumptions. That is why we need enforced social norms around disclosure.

Exactly! The code used double as "proof of work". Well-formed language used to double as "proof of thinking". And that's what AI breaks: it speaks, but doesn't think. And my core point is that language that does not originate from well-reasoned human effort (i.e., from either writing the language directly, or from writing such code manually that generates the language deterministically, and for known reasons/intents), does not deserve human attention. Even if the "observable behavior" of such language (when executed as code) looks "alright".

And because I further think that no code should be accepted without human review (which excludes both not reviewing AI-generated code at all and having some other AI review the AI-generated code), I conclude that AI-generated code can never be accepted.

I liked how you highlighted memory structures (short-term, medium-term, and long-term), allowing LLM Powered AI agents to maintain context and become the game-changer for these new generation chatbots. This moment mirrors the leap from IVR menus to live chat—but the potential impact here is exponentially greater.

Few challenges and areas that needs further discussion

Bringing Customers trust on AI agents to handle sensitive or financial information?

Interesting to see regulation shaping the use of LLMs in customer service?

How well this play out for small businesses that don’t have high tech budgets?

Hybrid collaboration feels like the sweet spot now, it will be great to see some case studies of brands that coexist LLMs and human support successfully.

> The point remains that it's very useful to have a memory management approach that can turn the RAM you've already paid for to reduce CPU consumption.

That approach is specifically arenas: if you can put useful bounds on the maximum size of your "dead" data, it can pay to allocate everything in an arena and free it all in one go. This saves you the memory traffic of both manual management and tracing GC. But coming up with such bounds involves manual choices, of course.

It goes without saying that memory compaction involves a whole lot of extra traffic on the memory subsystem, so it's unlikely to help when memory bandwidth is the key bottleneck. Your claim that a 200MB working set is probably the same as a 100GB working set (or, for that matter, a 500MB or 1GB working set, which is more in the ballpark of real-world comparisons) when it comes to how it's impacted by the memory bottleneck is one that I have some trouble understanding also - especially since you've been arguing for using up more memory for the exact same workload.

Your broader claim wrt. memory makes a whole lot of sense in the context of how to tune an existing tracing GC when that's a forced choice anyway (which, AIUI, is also what the talk is about!) but it just doesn't seem all that relevant to the merits of tracing GC vs. manual memory management.

> we're not seeing any kind of abandonment of tracing GC at a rate that is even close to suggesting some significant economic value in abandoning them

We're certainly seeing a lot of "economic value" being put on modern concurrent GC's that can at least perform tolerably well even without a lot of memory headroom. That's how the Golang GC works, after all.

If solar is "ridiculously cheap" (per GGP) and California has abundant supply of it, why does electricity in major cities in California (see e.g. https://fred.stlouisfed.org/series/APUS49B72610) cost several times what it does in Toronto, Ontario (https://www.oeb.ca/consumer-information-and-protection/elect... , and note these prices are in CAD)?

Only defeated entity here is US arms industry. Ukrainians are having their own long range weapons FP-1 to FP-5 (Flamingo). This stupid behavior is sending signal to everyone else that US industry is unreliable and should be absolutely avoided.

USA is doing exactly same mistake as Swiss did at the beginning of the war when they refused to allow use of Gepard ammunition in Ukraine. Rheinmetall bypassed them by setting up factory in Germany and European stopped buying weapons from Swiss arms industries as a response https://www.swissinfo.ch/eng/foreign-affairs/european-nation...

1. It's novel, meaning we have time to stop it before it becomes normalized.

2. It's a whole new category of threat vectors across all known/unknown quadarants.

3. Knowing what we know now vs. then, it's egregious and not naive, contextualizing how these companies operate and treat their customers.

4. There's a whole population of sophisticated predators ready to pounce instantly, they already have the knowledge and tools unlike in the 1990s.

5. Since it's novel, we need education and attention for this specifically.

Should I go on? Can we finally put to bed the thought-limiting midwit take that AI's flaws and risks aren't worth discussion because past technology has had flaws and risks?

You added the phrase "unique passenger" yourself. The article doesn't talk about that at all. It does use the phrase "passenger journeys" and "passenger numbers". While this sentence could perhaps be slightly better phrase, in context it's pretty obvious that it's talking about the number of journeys. All of this is a classic extremely pedantic and obnoxious cherry-picking.

Congrats on building and releasing this passion project! I love the hand drawn aesthetic. You had a vision and made something totally unique on your sabbatical. I hope you don't get bogged down in making it more "accurate" and "comprehensive" (unless you really want to!).

Similar to you, I worked in bike shops for years before getting into web development, so naturally some of my first toy-projects were an attempt to combine what I was learning with what I knew about bikes -- for example, a diagnostic tool based on the sound your bike is making (http://nathan.codes/showcase/#bikegnosis). It will be imperfect, just like your bike, but it will be totally your own!
