That's definitely still where I see the appeal of PLA, and once I get through the too much bulk PETG that I own I may mix up my future purchases to have more PLA where I don't need load strength and won't have issues with high temperature usage.

I am getting reasonably consistent prints but they aren't perfect.

The long version of my tips for using PETG are:

- A Bambu Lab printer doesn't hurt since it's so nicely calibrated and idiot-proof

- Clean the build plate with dish soap and dry fully. I haven't found any need for glue stick on a textured plate.

- Using a filament that has a profile available from the manufacturer for Bambu lab printers

- Printing with the filament in the dryer with the dryer running during printing

Today I learned that I would make a terrible detective!

When I watched Broadchurch with my family, I thought he was doing a fine job at getting to the bottom of the case. Goes to show much crime drama I watch.

I see now that Tennant's character's actions are a plot device to reveal the drama amongst the other characters, not the workings of a good detective.

You are correct on both points, which you elucidated well. Let's me differentiate the two systems based on "who-to-trust".

- The observe-system operates on an adversarial basis. The people observing the voting process are state officer, independent observer, each party's observers. If you vote for party X, then you trust that party and its people to do right by you. This include trust party X's observer, who additionally is often a local well-known person. You can actively distrust all the other observers and officers, and as long as your observer gives the A-Okay, you are happy with the result. This trust in your observer is a very simple human kind of trust. No expertise is needed by your observer. If you trust other observers, your trust in the result goes even higher.

- The stats-system is founding its trust in the trustworthiness of the stats experts. The problem is that (1) you don't know the stats expert personally. In fact, a huge chunk of the population in any country doesn't know anyone who is good enough at maths and stats. If people in your family are not the math type, your friends will also not be the math type. (2) It is incredibly easy to sling mud at the expertise and trustworthiness of an expert. This process is operating at a very high level these days on social media. Anyone remotely connected to politics is continuously character assassinated by others. Adopting a stats-system actually will actually increase this mud slinging to new heights.

The observe-system is better because as someone else has said, all the counters and anti-counters to it have been known for 100s of years. Breaking it requires breking 100s or 1000s of polling stations across the country. The stats-system has more central points of trust which can be broken more easily.

This is awful but hardly surprising. Someone mentioned reproducible code with the papers - but there is a high likelihood of the code being partially or fully AI generated as well. I.e. AI generated hypothesis -> AI produces code to implement and execute the hypothesis -> AI generates paper based on the hypothesis and the code.

Also: there were 15 000 submissions that were rejected at NeurIPS; it would be very interesting to see what % of those rejected were partially or fully AI generated/hallucinated. Are the ratios comperable?

If this is true, then why does it seem like the places with the least diversity are full of people Hell-bent on directly destroying the country?

There's some truth in what you're saying regarding social cohesion, but you're skipping some very important steps like the media fanning reactionary flames by scaring rural dwellers that "diversity" is going to come for them, etc.

Meanwhile people who are confronted with actual diversity in their day to day lives are less likely to buy into such simplistic and destructive narratives in the first place.

I hear you. I'd say the value prop is drop-in integration and customization with Rails, time-saving design (useful for 0-1 or early-stage ideas for non-design-savvy folks), and fewer headaches compared to adapting other components or themes in the wild into a Rails app.

No matter what you choose, there's work to be done to adapt to each app's use case, branding, copywriting, etc. Rails UI definitely isn't "complete" and is a constant work in progress, hence the subscription model.

Whether that's valuable to you is definitely up to you. Some folks don't want to be beholden to an AI for design and prefer a ready-made human-engineered system to refer back to and evolve as their app does.

I use this project for my own stuff. That's why I originally built it; however, I'm biased and am deeply on the Rails bandwagon. Ultimately, it saves me a bunch of time, which to me is the most valuable thing there is.
Show HN: VibeFarm – A non-generative IDE for composing AI prompts
by vibefarm | 2026-01-22 16:02:32+00:00
Creator here.

I built VibeFarm because prompt work kept collapsing into scattered notes, version chaos, and lost “recipes” across Midjourney, Sora, DALL·E, ChatGPT, etc. I wanted something closer to an IDE: structured, reusable, and model-agnostic, not a chat wrapper.

VibeFarm is a non-generative prompt composition workspace. Prompts are built from semantic slots (subject/context/style/etc.), optional layers, and saved snapshots (“VibeCards”) that export clean prompts to any model or to a portable .vibe JSON format.

Design choices:
- No generation inside the app, it’s intentionally just composition (no model lock-in, no API costs).
- Static curated vocabulary: 20,000+ palettes, ~1M fragments, instant drag-drop, no runtime calls.
- Reuse-first: variables for series swaps, video-mode timeline overrides, and versioned snapshots.

Try it instantly (guest mode): https://app.vibefarm.ai
Homepage: https://vibefarm.ai
Optional demo video: https://youtu.be/IgEly7VpwwI

Happy to answer questions or hear feedback, especially from people doing structured or repeatable prompt work.

I don't see any energy security for the future for the UK unfortunately. We sold ourselves short during the GW/Blair Neo-labour era. Scotland maybe, they have wind-farms but the UK likes to tax that. We've just started the era of paying for the cost of Brexit. It's hitting hard.

A supermarket shop for the basic essentials (cheese, eggs, flour, vegetables) now come to around $60/80 a trip.

Pamantasan Cheese is around ~£22-£45 ($30-$60) per kg compared to the US $7–$24+ per kg.

Going through a retraction and blacklisting process is also a lot of work -- collecting evidence, giving authors a chance to respond and mediate discussion, etc.

Labor is the bottleneck. There aren't enough academics who volunteer to help organize conferences.

(If a reader of this comment is qualified to review papers and wants to step up to the plate and help do some work in this area, please email the program chairs of your favorite conference and let them know. They'll eagerly put you to work.)

"Common core" math is an attempt to codify this style so more kids can get a deeper understanding of numbers instead of just blindly following steps. Like the people that created it noticed people like you and me (I do something similar but not quite the same) have an intuitive understanding of math that made us good at it that they want to replicate for everyone. But it seems like very few parents and teachers understand it themselves, resulting in a blind-leading-the-blind situation where it gets taught in a bad way that doesn't achieve the goal.

Also aside, in the method I was taught in school (and I assume you and GP from terminology), "carrying" is what you do with addition (an extra 1 can be carried to the next column), "borrowing" is for subtraction (take a 1 away from the next column if needed).

That works as reference to a frustrating situation, but Charlie Brown doesn't just miss. We assume that if the football was left where it was promised, he would have kicked it.

Maybe you suspect a similar situation with the Democrats, that those holding power sabotage their efforts, or maybe the analogy doesn't work in that way, but I think that people like this Charlie Brown trope because his failure isn't the result of a lack of ability; it's an excess of hope and trust.

I've heard plenty of people say that Americans are idiots because they don't realize the system is rigged against them and they believe the American Dream that anyone can achieve success. I think plenty of them know that the world is a harsh place with untrustworthy and adversarial people and that they are at a personal disadvantage compared to the wealthy and powerful, but they choose to persevere regardless because they believe hope is better than nihilism.

That can work against them. They might vote for a political party even if it fails them. I'm not saying that kind of hope is sane or rational from a game theory perspective, but it's very American to keep it up anyway.

Police are allowed to summarily execute fleeing violent felons. It does look like she barely nicked him with the car, which technically is felony battery on a a police officer. I will say I don't have all the facts, nor do I agree with the morality of the shooting, just to note the police are allowed to execute people even not in self defense.

If we judge him by, say, civilian standards in Minnesota though there was no excuse as it is a "duty to retreat" state and he had a clear path of retreat.

I’d like to play with an array language because I’ve never used one. I don’t want to pay for it; this is just for fun and as an experiment. I also want to run it locally in a shell, writing it in a local editor, not working in a web UI. And while popularity isn’t everything, and none of these are exactly Python levels of widespread, I also don’t want to find myself learning a cool one along with 3 other people in the world and then find out all other array language programmers do things completely differently. (Analogy: I don’t want the equivalent experience of picking Haskell as my first ever PL.)

This topic tends to bring up a few, like APL itself, J, K, and BQN. Given those (soft!) constraints, what’s the one I want to start hacking around with?

What? No Canada isn't cheap solar power -- last I checked rooftop ballasted solar is a 12-14 year payback on avoided costs. Inverter will go beforehand and that excludes any op costs. 8k$ free loan doesn't really provide as much value as you would think.

FWIW - I am all for solar but selling rooftop solar in canada as cheap and no-brainer is false.

3-4 year payback would be a no brainer. 8-13 year payback with an inverter upgrade and op-costs is definitely a decision that needs to be thought out.

The grid you are offsetting is fairly green to begin with so the net benefit is marginal.

If you are going to be isolated and put backup power into the equation. You ROI tanks further but at least you have about a day or two worth of energy in the storage asset.

I'm not sure I understand the Burroughs example as relevant to the UK, but another good illustration is Thomas Hardy. His books sold well but were never seen as consistent with the UK cultural mainstream, and the reaction to Jude the Obscure in 1895 stopped him from writing novels entirely. Yet post-WWI he came to be seen/adopted as a mainstream cultural icon.
by blindstitch | 2026-01-22 16:04:46+00:00
Thanks for all this, what you wrote and the discussion that followed has been genuinely helpful, and I think it might help bridge some cultural divides that I've experienced when working with Indian people.

Another question I'd like to ask of you is, do you see any aspects of the western style of cooperation that are the inverse? i.e. which create divides in which the westerner's ways of working can be the source of conflict?

If MS abandons WinNT, then people will likely continue to use the existing versions of Windows which are out there for any existing software (just as people continue to use MS-DOS and Win 9x for old games and software).

As for new software - I think it's open to debate just how much new Win32 software will be created after a hypothetical abandonment by Microsoft of Windows.

It's always valuable to have a generalizable skill. But design is fundamentally a craft; an applied art. It's problem-solving. And like any craft, there are tools and techniques that are tried and true. You could approach woodworking with a ground-up Systems Thinking approach, but would you turn down the advice of a carpenter with 30 years of experience? Technically all you need to understand woodworking is a physics textbook and maybe an organic chemistry textbook.

My guess is you're a software developer (as I am), and in my opinion the fatal flaw of our group is the incorrect belief that we could do anything or solve any problem by simply decomposing it into smaller and smaller components. The thing is, for a big enough problem, there are an almost infinite number of ways to break it down and then build it back up. In optimization terms, complex projects are highly nonlinear problems, so you may be able to understand what the inputs are, but it sometimes takes wisdom and experience to tune the parameters.

this is not a launch post or a startup update.

a month ago i was deep in hacker/creator circles, building and learning fast. then college apps and burnout hit and i disappeared.

coming back was brutal. everyone i used to talk to kept building. but i didn’t.

so i’m not doing anything special. i’m just going to post for 30 days to get back into my rhythm.
i want to get back to thinking, building, and sharing work in public the way i used to enjoy.

posting this here because HN is one of the only places where showing real work actually matters. if this resonates, i’d love to build in public with people who actually care about the work.

This is nice and all, but what repercussion does GPTZero get when their bullshit AI detection hallucinates a student using AI? And when that student receives academic discipline because of it?

Many such cases of this. More than 100!

They claim to have custom detection for GPT-5, Gemini, and Claude. They're making that up!

When you print objects with 10's of printers 'tuning your 3D printer' is no longer an option other than to tune it to be 'in spec' You can only tune your designs and the profile for your filament and for a particular model of printer but then all of those have to be close to identical. As soon as you start tweaking your design or filament profile to offset possible issues with the printer you've lost reproducibility.

Incidentally, a lot of the stuff on thingiverse and other similar sites suffers from those kind of issues. They are tuned for PLA on a particular printer without realizing it.

When I was reviewing such papers, I didn't bother checking that 30+ citations were correctly indexed. I focused on the article itself, and maybe 1 or 2 citations that are important. That's it. For most citations, they are next to an argument that I know is correct, so why would I bother checking. What else do you expect? My job was to figure out if the article ideas are novel and interesting, not if they got all their citations right.

That's not my recollection of the events. I think "showed us who he really was" is just the FUD spread by the Liberals. I have left leaning friends and their opinions of PP are totally disconnected from the reality of what he says and does, they are just repeating the talking points they get from their circle.

Nobody wants to debate actual policy and basically we ended up with a different conservative, Carney, whose actual policies are in my opinion iffy ans his performance the same. Scare tactics are easier than policy debate.

Merge algebra is similar to git with a three way merge. Given that lix tracks individual changes, the three way merge is more fine grained.

In case of a conflict, you can either decide to do last write wins or surface the conflict to the user e.g. "Do you want to keep version A or version B?"

The SQL engine is merge unrelated. Lix uses SQL as storage and query engine, but not for merges.

Every time, over the years, that there has been some kind of headline saying renewables have overtaken fossil fuels, when you look at it a bit more closely there is always a big 'but'. For example, it was compared to coal (not taking into account electricity from gas), or it was for one day, or it was a percentage of new installations, or it excludes winter, includes nuclear etc.

This time, however, it looks like it's actually true and that's just for wind and solar. This is incredible, and done through slowly compounding gains that didn't cause massive economic hardships along the way.

I’m not a game designer, but 15 years after initially reading it, Jesse Schell’s “The Art of Game Design: A Book of Lenses” really sticks with me in any product design context. Organizing your thoughts around the lenses presented in this book makes for productive discussion, and can turn subjective points (an example might be how frictionless or not a UI element might be) into more objective points. I suggest checking it out. The author posted a deck of the lenses here: https://deck.artofgamedesign.com

I like to say "my code is 200% vibe-coded; the tricky bit is figuring out which 100% to keep".

Decisions matter, both technical and product ones. LLMs don't make as good technical or product decisions as I would, and the way I work with them tries to maximize my strengths and the LLM's strengths. I don't know if I succeed, but it's better than "make me an app like X" as a prompt.

The article is fascinating, but posits that the controversy of when death begins was something of days past.

The Uniform Determination of Death Act settled it legally for the US, but only legally. Emotionally, and sometimes even practically, it remains a haunting question with answers that may be both true and false at the same time.

Sad to hear of the doctor whose career and reputation were sideswiped by popular, religious objections to his opinions on the matter.

Europe has fantasies of being a mighty empire but actually all it does it lick the butt of actual great empires. Also Europe is a little baby, it wears diapers and poops in them all the time and doesn't even know what toilet training is, then they need mommy to come change the diapee or else Europe will cry and scream and throw a big tantrum.

In my experience trying to outsource to India, there is a strong systemic bias towards lying and cheating to get ahead (and that was even before AI), and a focus on milking as much money as possible rather than building great technology.

While there is real talent there, there is also a lot of overhead to find people you can trust.

This is probably just a reflection of the competitive nature of the market and the social ladder tech salaries enable there.

If your product has code on it that can only be understood and worked on by the person that wrote it, then your code is too complex and underdocumented and/or doesn't have enough test coverage.

Your time would be better spent, in a permanent code base, trying to get that LLM to understand something than it would be trying to understand the thing yourself. It might be the case that you need to understand the thing more thoroughly yourself so you can explain it to the LLM, and it might be the case that you need to write some code so that you can understand it and explain it, but eventually the LLM needs to get it based on the code comments and examples and tests.

Totally agree, WW1 is really the root cause of all of Britains problems.

Victory wasn't worth the cost. It would've been better to give the entire empire to the Germans to maintain peace. It'd be lost anyway in a short amount of time. Even forcing King George and Kaiser Wilhelm to marry would've been better for them than German Republicanism and the British Royals becoming Kardashians with crowns.

I’m Indian. I absolutely loathe this part of Indian culture. My uncle was once eating a pizza like a naan (ripping pieces off straight from the box) and I called him out on it, and he said he wasn’t doing anything like that…while holding a piece of naan and the pizza looking like rats had a party with it.

It happens basically constantly, I have never heard my family admit to a mistake unless violently confronted by someone with authority.

Leads to all sorts of issues and societal breakdowns, like police beating people up before even trying to communicate.

Design thinking, at least in its formal STS approach, is essentially applied sociology; it's about using various toolkits to build a sufficient understanding of a domain from the "inside out" (using desk and field research) so that you can design valuable experiences that build upon the expertise of those actually inside the domain. In this, it's a bridge between UX/product and users/stakeholders (technical stakeholders are admittedly too often an afterthought, but that's a process problem). If anyone comes in and attempts to blindly shove workshops at you without first conducting in-depth research, interviews, and field studies in your domain, then they are (without resorting to the One True Scotsman) not doing design thinking, they're doing cargo-cult brainstorming. (It's also a process orthogonal to agile development, since by definition it's a linear process that needs to be conducted prior to developing the actual product features and requirements.)

The books and papers the OP cites are solid (Rittel and Webber, Buchanan, etc., though TRIZ, I think, is rather oversold), but in my experience the problem with most design thinking practitioners is that they aren't qualified sociologists and ethnographers, so a lot of design thinking is basically a reinvention of the last century of sociological middle-range theory and ethnographic principles, without being strongly informed by either, likely due to the field's foundation in early software requirements studies.

I still see this as a design flaw, even if it explains why it was done. They save a little in manufacturing, and then thousands of people per day end up using it wrong for decades, in the case of a high traffic door, like at a mall.
