By your response, I think you've flipped the bozo bit on me. I will try again.

I'm most certainly not asking for irrefutable proof. I'm asking for a concrete example of how you know, in a way that that would inform me and others in your readership:

1) how do the results from a TDD prompt compare to a good quality test-last prompt?

2) following the TDD approach, what are the steps to get from the initial solution, with errors and untested code, to one which passes human code review?

There's a long history of how Postel's Robustness principle combined with the difficulty of following a spec closely results in a fractured and incompatible ecosystem. We have enough deliberate Markdown variants without needing to introduce a new one by happenstance. This informs my belief that something claiming to parse Markdown requires extra attention to the details, beyond what a one-off toy example would need. That's precisely why I think this is a good example problem.

I'm not tracking what's going on with agentic programming. I don't know who Jesse Vincet is or how his Clause skills are relevant. Is the target audience for your book those who know what what those mean, or developers like me who don't?

What I do know very well is what robust tests look like, and what TDD is supposed to look like. I didn't see it in your example, and would very much like to see a full example of a non-trivial problem like this one worked out, and compared to a non-TDD agentic approach.

That level of analysis is missing from almost every TDD example, which tend to use a toy problem to walk through the mechanical details of the red-green step, with little attention to -- or need for -- the refactor part, which is the hardest part of TDD.

I'll also note that I seem to be the only one here who commented about the generated code quality and fitness to task. I mourn that so few care about those details.

IANAL, so take this with a grain of salt, but:

As with all things, who are you going to get in trouble with? And what's so magical about legal practice as opposed to, say, giving shitty medical advice or telling someone how to build porch? Asking genuinely. No one falls all over themselves to say "I am not a doctor, but...", even though their next words could kill someone. The implication is that they don't have formal training but they saw something on Facebook that you should try. What happens next is on you, not on them.

I mean thats a big number, but if you think about the amount of lakes needed to run hydro, its not actually that much of a number.

I'm not saying musk is a clever man for pointing this out. Even greenpeace said stuff like this in the early 2000s.

the point is, it sounds bigger than it is. For oil storage, the US has something like 36 square miles of storage (converting from cubic to square isnt accurate)

People are nostalgic about these places

Not I. The same sales people I had talked to the day prior would pretend to not speak English the next day. Their employees would put all the returned items back on the shelf and to comply with the law they would put temporary stickers that said "returned item" but the stickers would very intentionally fall on the floor within an hour. Friends made videos in the stores regarding this behavior and the stores called the police on them every time. The police would always side with the store likely due to the delicious sales tax funding them. Employees would improperly handle RAM and repackage it as new. A couple of them interviewing at a company I worked for even admitted as much. In my opinion a swap-meet would probably have been a safer place to buy gear. This was in Fremont, California.

As for the banks I doubt it decreases security. Even SMS 2FA actually reduces fraud by 90%+ percent.

Yes, some banks implement it silly, like SVB requiring biometric login in order to scan one-time QR 2FA code from their app (biometric login is less secure), but you don't have to use the QR code, can use regular 2FA without biometrics.

But even then having 2FA is 42 times better than not having it.

I strongly believe that if you set aside genre preferences the solid body electric guitar coupled to a tube amplifier is objectively the greatest electronic instrument ever created.

All other electronic instruments, with the one exception being the Theramin, have a fundamental problem with human expression. There is an unsolvable disconnect between what the performer's actions and their audience.

See: https://www.scribd.com/document/55134776/48787070-Bob-Ostert...

With an electric guitar you get the physicality and dynamism of an acoustic instrument with the complex timbres and extended technique possibilities of an electric/electronic instrument.

There are complex and musically significant feedback loops occurring across many dimensions that lead to extremely complex transformations of timbre via both traditional music theoretical techniques and the physics of a tube amplifier combined with an inductive load (the guitar pickup).

Its really crazy how much more dynamic and complex this can be then even a highly sophisticated modular synthesizer or whatever. Even the way you over load the power supply in a tube amplifier can be manipulated on the fly to enhance and transform timbre.

Then on top of all that it is so incredibly physical that a performer like Jimi Hendrix can manipulate these systems and have the audience intuitively understand what he is doing. Never in a million years would THAT be possible with any other electronic instrument.

I am personally of the opinion that that's more a PR thing than a genuine change of heart. I would very much love to be proven wrong, but the acts of Oct 7 really don't give me much hope there.

I think both have significant genocidal intent, if the world will let them get away with it, but only one party has genocidal capacity.

For people that don't watch the video (I don't even know if this is in the video): road wear is a function of axle weight to the fourth power. [0]

That means a 6,000lb escalade creates 3x the road wear than a 4,500 wagoneer from 1990.

Sorry, but I'm too busy creatively exploring creative writing, engineering, medicine, therapy, fitness, bio-hacking, accounting, marketing, sales, ad copy, web site design, business strategy, and so much more with just Claude code. I'm maxing my weekly max x20, and this thing is good. It is better than me and every professional I've met in my entire life.

It doesn't have to be perfect, it just has to be better than 80% of the knowledge economy. It's there. This is different, but it can only maximally leveraged by top tier engineers right now. That will change in eight months.

I gave you a super power prompt, and you want more? Respectfully, shame on you.

This isn't a good thing unless it's paired with storage and transmission upgrades. Every time this kind of story posts I make this same comment and am met with the same probably well-meaning but ignorant responses. Solar generation is easy and cheap and simple. Actually getting that power where it needs to be, when it needs to be there is complex and expensive. You either need to store it or you need to transmit it very long distances, neither of which we can do effectively right now. Most of California routinely goes into negative power pricing - this is not the mark of a healthy system, it represents a massive inefficiency and destabilizing factor.

We need to pressure politicians to subsidize pump storage powerplants and massive transmission system upgrades (which means being ok with permitting new transmission lines) it's simply impossible to continue increasing the solar on the grid otherwise, we are rapidly approaching instability.

On one hand, I don't feel strongly about this because I literally never use these builtin Windows tools. I can't help but think it'd just make more sense to include VSCode builtin though. It's already very good and has a nice startup time, and then you don't need to screw-up fundamental system utilities that are more break-in-case-of-emergency then something that should be feature rich.

Being a draft, it deprived Gates any opportunity to respond, so it's possible Epstein was playing "4D Chess" and planting defamatory disinfo in anticipation that his emails would be subpoenaed in some civil suit and leaked to the public, but that seems much less likely than Epstein boorishly bringing up an unpleasant episode that in fact did happen to use as emotional leverage over gates. (Epstein was known to be very pushy.)

It's also crazy to see a man like Bill Gates willingly compromise himself in this manner. Even setting aside the Epstein affiliation, did the Russian spy angle just not occur to him?

I felt it quite a while back (more than 10 years ago), when, in high school, I learnt LaTeX and discovered Beamer. I naturally proceeded to make all of my presentations with it, including the rehearsal for a big competitive French exam. The person reviewing the presentation advised me to dirty it up a bit, otherwise nobody would believe that my father wasn’t a PhD researcher that did the work for me.

That was a bit saddening honestly. I kept the presentation as-is as I didn’t knew how to willfully screw up a Beamer presentation, and I would not touch PowerPoint (fortunately the final jury believed me).

Cheating had always been an issue before LLMs, but now we’re back to the same old tricks: just make sure to add a mistake or two to hide you copied the homework on your neighbor. It’s a shame because I kinda like learning the subtleties of foreign languages, and as a non-native English speaker, it’s quite rewarding when going online!
Show HN: Opty – A Zig-based HDC that reduces token use by up to 90%
by bojo | 2026-02-25 21:29:18+00:00
I kept seeing people all over social media talking about how they were making custom local-LLM systems to help reduce the token load injected into their context window.

On the side my recent project has me looking at Hyperdimensional Distributed Memory. I couldn't help but wonder if I could make an MCP server to improve token usage. Sure enough, using a combination of HDC + TOOL format, I was able to get opty's own self audit down by 93% in token usage.

Still experimenting with large codebases but feel pretty good about how this should drive overall token usage down.

Happy to hear any feedback.

At least in Melbourne, the tram network genuinely does have too many stops. Stops which are only a few minutes walk from each other.

Which results in the trams being incredibly slow compared to driving even if they are frequent, clean, and generally nice. Since the network already needs total overhaul to be wheelchair accessible, there has been a plan to combine 3 stops in to two wheelchair accessible ones. Which will also speed up the trams since they don’t have to stop as often.

I am not a literature lover. I found a modern language interpretation of the poem. Many interpretation are possible. But I feel this is relevant.
I translated it to English.

============

おほけなき床の錦や散り紅葉 "Ohokenaki toko no nishiki ya chiri momiji" is interpreted as a haiku-like expression of introspection and refined aesthetic sensibility — one in which the speaker, surrounded by undeserved honor (ohokenaki) and luxurious living (toko no nishiki = sumptuous furnishings), gazes upon the fleeting falling autumn leaves and reflects on their own vanity and attachment to life.

Key points of interpretation:
おほけなき Ohokenaki (身の程知らず /畏れ多い): Refers to a luxurious situation or standing that exceeds one's true worth or station — something almost presumptuous to possess.
床の錦 Toko no nishiki: Literally, a beautifully brocaded floor covering; a symbol of opulence. By extension, it evokes the sight of vivid autumn leaves carpeting the ground — the splendor of autumn (nishiki-aki) likened to a gorgeous spread of fabric.
散り紅葉 Chiri momiji : Falling, scattering autumn leaves — a classic symbol of impermanence and the Buddhist sense of transience (mujo).
Overall picture: The speaker finds themselves in lavish surroundings that feel undeserved (ohokenaki), while the scattering leaves (mujo) adorn that world with a beauty that is at once gorgeous and hollow — a quiet contrast between humility and the ephemeral.

Even amid a life of splendor, the sight of leaves falling reveals a universal truth — that all things must eventually end. The poem captures a mood that is gently melancholic yet elevated: savoring that beauty from a place of quiet, dignified acceptance.

Oh, 350 prototypes were built. Many were incomplete. The finished ones tended to go home with engineers--TI didn't exactly watch what went out the door.

I owned a 99/8 (without Pascal GROMs), so for me it was definitely real! Extended BASIC II was onboard, and showed this:

> SIZE
62235 BYTES FREE

The manuals and most schematics are long known and archived at ftp.whtech.com. I have/had paper copies of many of them. Sadly, TI never archived any Home Computer work from Lubbock, TX. Those employees had been laid off or transferred just as TI got interested in preserving archives (starting in 1983. Described in Ed Millis book: TI, the Transistor and Me.

The TI Records are at DeGolyer Library, SMU but contain very few Home Computer folders. Conspicuously missing are the papers of CB Wilson, which turned up at an estate sale and were fortunately scanned.

Wilson's office in Dallas seems to have contributed a few things to the archives. That is typical: mostly executives and Fellows were canvassed for documents. Ed Millis revived obsolete floppy formats for the cause in 1983!

I really appreciate your commentary here! I understand that SQLite would not automatically solve the politics issue. As ctoth mentioned, it would serve as a "flag day" for the KeePass community to hopefully cover everyone's bases in a formal manner. Schema versioning and evolution is way more up SQLite's alley. An SQLite schema has referential integrity which an XML schema lacks, making it harder to misuse and contort. It is also far simpler to modify a query in the event passkey storage need to be changed than it is to modify the parser.

The lower barrier to entry probably also reduces the number of catastrophic parsing mistakes a developer can make. This is a net positive gain for the wider ecosystem of external tools which do not have to re-implement the whole parser. Every language has a great SQLite library, the same cannot be said of KDBX.

This thing seems to be more about enforcing a political PoV than about avoiding logical fallacies.

All my attempts to comment on the UBI article (and not supporting UBI) said my comment was a dogwhistle, and/or had an overly negative tone. This topic, of all things, is absolutely worthy to challenge and debate.

Using this would have the effect of creating an echo chamber, where people who stay never benefit from having their ideas challenged.

Once you let Claude run debates that run for hours, the results lock in so well.

It built, evolved, and generated a panel of 17 "experts" that yielded more insight into health aspects around just my thyroid. I got the absolute best representation of the entire discussion around different options I've seen in my entire life.

It's AMAZING.

I can't speak for the specificity of parent's "evil maids" phrase but the concept of an "Evil maid" is used in security scenarios.

A maid tends to be an example of a person who's mostly a stranger, but is given unmonitored access to your most private spaces for prolonged periods of time. So they theoretically become a good vector for a malicious actor to say "hey I'll give you $$ if you just plug in this USB drive in his bedroom laptop next time you're cleaning his house" - it's often used in the scenario of "ok what if someone has physical access to your resource for a prolonged period of time without you noticing? what are your protections there?"

I wonder if that's what OP meant? :-)

Because the opponents of it have the deepest pockets of literally anybody in the world.

A whole class of parasites who have made their lives as highwaymen on the densest energy source (outside of uranium) -- that literally comes out of the ground -- have spent at least the last 20 years actively suppressing alternatives.

In some places (see Alberta, Canada), they have literally outlawed renewable developments.

In this context political advocacy, education, and subsidy remain absolutely imperative.

There is no "free market" way out of the current situation regardless of how economically viable solar is. In the real world markets and power are intrinsically linked.

It's also actually also an emergency

What's the target?

If you're deploying applications to desktop/laptop, Microsoft stack seems like the biggest market share by a lot.

Anything else, probably not. Microsoft may have advantages in servers, or at least they have had some in the past: my go to example is Receive Side Scaling [1] was originated at Microsoft and is amazing in some use cases. But those advantages most likely aren't big enough to justify the hassle of wrangling and paying for licenses. Running your servers on open source software makes everything easier.

> Saying it's "fully conscious" is silly, and anyone with this background should know better

I'm surprised that anyone that truly knows how LLMs work would ever think they're sentient.

I made a little presentation for my colleagues last year to explain how LLMs really work (in an effort to stop them from asking it too many stupid questions) and it made so much more sense to them afterwards.

1. Just saying, strange coincidence

2. How can we compare Claude's output in a different language?

3. Detecting break-ins and handling evil-maids: unless the trick is already known on the internets, I do not disclose. Odds are not in my favor.

4. Maybe worth, maybe not. I have my adaptations. Trying to make it not worthy of stealing, in fact.

I took a Greyhound a couple of times when I was in the US, and the experience immediately showed me why Americans hate buses and coaches.

My first transfer was in Sacramento. The entire bus got held up for over an hour because someone saw a man with a knife and security had to search absolutely everyone to try to find it.

Half the stations were literally crumbling, as in the ceilings were falling down and covered in water stains and flecks of black mould. The drivers often turned up hours late, which is apparently expected and normal. The stations tended to be in exciting hotspots such as Skid Row, to cater for the desperate clientele who had no choice but to run the gauntlet.

Also, after the first time I rode it and told everyone about the knife that nobody ever found, people started showing me news stories about the man who got beheaded on a Greyhound in Canada.

Overall I think they have very patchy bus and coach systems and over-index on the worst examples.

This isn't the dystopia we're worried about.

The dystopia we're worried about is a 1984 on steroids with llms and real 24/7 worldwide monitoring by the state.

Getting caught doing embarrassing things by teenage social standards doesn't threaten your life.

A competent version of Donald Trump could have walked into the office and we would have been worse than the third Reich.

Still could be today right now. The capability is TurnKey right now at the US government.

This is open research being discussed here. Palantir already has all of this and probably 10 times more.

I run https://wwww.clawdrop.org entirely using openclaw.

- it crawls/scrapes to source the material (like this thread).

- dumps it in a sqlite db

- breaks apart raw source into individual use cases

- scores it based on the types of readers I have (solopreneuer, creator etc.)

- creates the template in my CRM, ready to send

I review and edit it at the end.

Still working out kinks, but its been great for:

scrape -> dump -> content/digital product

doing this on both, the supply and distribution side.

i’m confused why that feels staggering to you.

Do you realize how generous their return policy is? How convenient it is to order from them, and set up a subscribe-and-save for monthly household items? Also consider how many people set up wedding or baby shower registries on Amazon.

I have been avoiding amazon recently for ethical reasons but i’m genuinely confused by your comment. It sounds like you’ve never shopped at amazon lol. And with inflation…$3k isn’t even that much money in the US. That’s $250 a month.

Another option instead of using identity is to use proof of work or hashcash such that anyone who thinks a comment is valuable can use some hash rate to upvote it. It doesn't matter how the content was generated, only that someone thought it was important, and you can independently verify this by checking how much hash effort went into hashing for that comment. This also does not require any identity either.

1: This "ADHD" issue is because you've never seen properly ran bus system. I used to live in big European city, riding bus to work everyday, and I never even knew the bus schedule. I did not have to. They would come every 15 minutes, or every 7-8 minutes during the rush hour. So I could just show up at the stop anytime and be sure that a bus will appear quite soon. Zero advance planning required.

> There was a time when people wanted to dig tunnels with nukes

The article seems to be about mining rather than tunnelling.

And the issue with the idea being? We also dig using explosives, there isn't an in-principle problem. Reading the wiki article it looks like the yields were excessive, but at the end of the day mining involves the use of things that go boom. It is easy to imagine small nukes having a place in the industry.

Main differences are

CLIHub

- written in go

- zero-dependency binaries

- cross-compilation built-in (works on all platforms)

- supports OAuth2 w/ PKCE, S2S, Google SA, API key, basic, bearer. Can be extended further

MCPorter

- TS

- huge dependency list

- runtime dependency on bun

- Auth supports OAuth + basic token

- Has many features like SDK, daemons (for certain MCPs), auto config discovery etc.

MCPorter is more complete tbh. Has many nice to have features for advanced use cases.

My use case is simple. Does it generate a CLI that works? Mainly oauth is the blocker since that logic needs to be custom implemented to the CLI.

Evil maids (example): I put my laptop into a safe, seal the safe, seal the room, go to breakfast. On return, I see there was cleaning (not the usual time, I know the hotel), the cleaner looks strangely confused, the seal on the safe is detached (that is often done by applying ice; adhesive hardens, seal goes off). This level of paranoia was not my norm. Had to learn these tricks cause problems happened (repeatedly). In fact, I frequented that hotel, knew customs and the staff, so noticed irregularities.
