This is conceptually interesting to me because I see this as almost a more generic TI Webench. I’m curious why your focus in the sized “grid” blocks (presumably for placement directly on the PCB layout) instead of doing the same but for the schematic. That way I still have the flexibility of laying out the board how I want to meet eg mechanical constraints instead of working around a 12.7mm grid.

All of these things are much more subject to the problem that effects policy generally: the law of unintended consequences. Betting on the policy, rather than an intended/expected longer-term outcome that is easily derailed by intervening events outside of your direct control is much more direct (plus, if you are corrupt enough to bet on policy you control, that policy is probably already seeking a longer-term aim that serves your existing financial interests, so the ability to bet on the policy itself makes the corruption more attractive by providing a more immediate and certain payoff on top of the longer-term, less certain one.)

The explosion of fake people on Instagram (which has become just a front-door for Other Form of "social networks"), as well as fake videos in general, will likely push people away from the Internet as a means to interact with other people.

I think old school meetups, user groups, etc, will come back again, and then, more private communication channels between these groups (due to geographic distance).

> I'm adamantly against all forms of illegal immigration

And Trump did what, exactly, make something already illegal even more illegal? And now that you are ruled by a de facto fascist with the rule of law only applicable to his enemies, how is the payoff? On the upside, illegal immigration is no longer a primary concern, I guess.

> I hate all taxes [...] because government is generally terrible

Better to let everything be run by cartels instead, surely they will have your best interests at heart. There's not a single example of a functional and effective government out there, so why even try?

>> Yeah, EU is super fucked too since it outsourced its energy dependence to Russia, consumer manufacturing to China, defence and tech services to US, and only just woke up in the last 3 or so years that it was all a huge mistake that's now costing us dearly since we're at the whims of all 3 belligerents who know that now is the time they can squeeze us.

The EU policies makes sense if the goal is peace and prosperity. You can't reach that goal without collaboration and trade. If you're going to blame someone, blame the Great Powers, the US, China and Russia, in order of importance, who have suddendly gone ballistic and can only talk of war, War, WAR, and nothing else.

Oh, sorry, President Trump is all about trade... tariffs.

I mean if the world has gone mad, don't blame the EU for trying to be sane.

Maybe some type of long physical probe you have to sit on and it generates a hash from the exact shape of your "cavity".

Seriously, am I the only one that would be happier without any of this "2FA" crap? VPS/Domain/Google with a hardware token is the one narrow scope where I see any value, and even those I could do without. Every other site is just a non-consensual nagging that hassles me when logging in. Bank accounts are the worst, as every bit of friction for checking my balance/transactions actually decreases my security!

That’s definitely a fair point. Currently for the tech company I am at we already require the candidate to download an internal video conferencing application to join the interview so I think it really depends on what you’re used to.

Also to answer your second question we’ve been finding it’s extremely difficult to detect by eye. Also we lack any video evidence to support our claim of cheating which can be problematic when we review the candidates.

As the cheating tools get more advanced I think it’s going to be impossible to detect without some sort of application running on the computer

The analysis is interesting, but I think it ignores a few factors:

1. The article mentions the bid/ask spread for contracts, but I believe that Kalshi also has its own fee structure. Small edges (an expected loss of 0.57¢ on a 1¢ contract implies an expected gain of 0.43¢ on a 99¢ contract, or a 5.75ppt edge) can be easily eaten by even small fees, and liquidity provision is all about small edges.

2. The article ignores the time value of money, and contracts take time to resolve. If a contract won't resolve for six months and the risk-free rate is 5%, then buying a "sure thing" over 97.5¢ is a loss net of otherwise earnable interest.

3. Long shots offer greater implied leverage to bettors, making them more attractive. This is still (sometimes) an exploitable mispricing, but it's closer to the well-understood "bet against beta" factor.

(Edit to add) Also, I think their explanation of the non-returns on finance is lacking:

> Why is Finance efficient? The likely explanation is participant selection; financial questions attract traders who think in probabilities and expected values rather than fans betting on their favorite team or partisans betting on a preferred candidate. The questions themselves are dry ("Will the S&P close above 6000?"), which filters out emotional bettors.

Financial contracts are the ones that are most perfectly hedges with existing markets. "Will the S&P close above X?" is a binary option, after all, so it's comparatively easy for a market-maker to almost perfectly offset their Kalshi positions with opposite positions in traditional markets.

The same financial products are used in both gambling and smart investing. The canonical example here being options. And the restrictions on what the public can and cannot invest in are complete bullshit. You can't buy shares in a series A startup because that is deemed to be too risky for anyone who is not an "accredited" investor ("accredited" here literally means rich). But anyone who wants to can bet on sports, go to a casino, or buy a 2x levered VIX ETF.

I've spent the last month building a 'Variance Scanner' to detect thread-blocking patterns in AI agents.

I ran it against OpenBB (Python-heavy financial tool) and Nautilus Trader (Rust/Python HFT engine).

The results were stark:

- OpenBB: 306 blocking calls (requests.get in main thread). Variance Score: 1602.
- Nautilus: 0 blocking calls. Variance Score: 99.

I call this failure mode 'Hydrostatic Lock' — when an agent hits a network spike and effectively brain-deads for 3+ seconds because of synchronous I/O blocking the GIL.

The repo includes the full forensic audit and the open-source scanner. Happy to answer questions about the methodology or findings.

Awesome stuff :) The results are really impressive.

GPU acceleration is a really good idea; my CPU implementation of a similar idea with triangles (https://github.com/anematode/triangle-stacking) was compute constrained for smaller images (which was fixable with good SIMD optimizations) but became bandwidth constrained for very large images that don't fit in L2. I think a port to OpenCL would have been a good idea.

In fairness to this report, the report is about tariffs and their impact on...imported goods affected directly by tariffs isn't it?

From an overall economic policy standpoint, missing facts that provide context are pretty important especially when you're trying to paint an entire side of the isle as completely brainwashed. Nobody can have a conversation when we create straw men to argue with.

Other relevant context:

- The US trade deficit just hit its lowest points since 2009 due to decreased imports and increased exports, which rose by record amounts.

https://www.reuters.com/business/us-october-trade-deficit-lo...

- US Q4 2025 GDP grew by 5.5%, outpacing China at 4.5%. For context, over the last 25 years China averages 8% per year while the US average 2.1% per year.

https://www.visualcapitalist.com/top-50-economies-real-gdp-g...

- US inflation has continued to slow at 2.7% with core inflation at 2.6%, continuing the trend from the last 2 years under Biden after a huge 9.1% inflation spike in 2022.

https://usafacts.org/answers/what-is-the-current-inflation-r...

- US gas prices continued to trend downward by national average, with significant regional drops. I live in South Carolina and filled up for $2.39 / gallon a couple of days ago.

- The price of eggs have come down significantly, to their lowest rates in 4 years.

- And the US stock market is at all time highs right now.

There's a lot of economic doom and gloom in the comments section here that's simply not reflected in the overall economic numbers. It's not perfect, but it's trending in the right direction.
Show HN: Subth.ink – write something and see how many others wrote the same
by sonnig | 2026-01-19 18:34:52+00:00
Hey HN, this is a small Haskell learning project that I wanted to share. It's just a website where you can see how many people write the exact same text as you (thought it was a fun idea).

It's built using Scotty, SQLite, Redis and Caddy. Currently it's running in a small DigitalOcean droplet (1 Gb RAM).

Using Haskell for web development (specifically with Scotty) was slightly easier than I thought, but still a relatively hard task compared to other languages. One of my main friction points was Haskell's multiple string-like types: String, Text (& lazy), ByteString (& lazy), and each library choosing to consume a different one amongst these. There is also a soft requirement to learn monad transformers (e.g. to understand what liftIO is doing) which made the initial development more difficult.

> What I'm saying is that the boundary between where you use a 'systems programming language' and where you use an 'application programming language' is artificial

Well, everything humans have ever created is artificial, so I'm not sure even how to parse this sentence. There are objectively tasks which can be accomplished with systems languages which cannot be with others. That is an indisputable fact, and not determined by anything but the language specification and implementation.

> we are using too much of the former in a place where we probably should be using the latter

If I loosen this sentence to mean that we should write more code in languages which have the familiar properties of applications languages - memory and thread safety, low boilerplate, helpful tooling, reduced cognitive load - then I can agree with it.

Where that code needs speed, uninterrupted control of execution, to be embedded, target wasm, or might want to do any of those things in the future, I think Rust is an excellent choice which provides many of those benefits.

I'd rather not have runtimes sneaking into low level performance critical areas like kernels and drivers. But some folks are into that sort of thing - Microsoft famously worked on https://en.wikipedia.org/wiki/Singularity_%28operating_syste... in C# but then again C# has very similar memory semantics to Rust. Microkernels seem to work well enough, with several extant examples. Anyway, you do you! I look forward to ogling your OS project from the sidelines.

What’s interesting to me is that no matter how “hidden” the AD indicator may be, my brain always seems to very quickly train itself to swiftly skip such posts when scrolling/browsing.

Or I could simply be another clueless victim of advertising. If only I could know the number of sponsored posts I never consciously acknowledge and am influenced by on the daily.

On the other hand, take LinkedIn for example, and you get the bottom of corporate AI-slop.

I agree that anonymization makes people more hostile to others, but I doubt the de-anonymization is the solution. Old school forums and IRC channels were, _mostly_, safe because they were (a) small, (b) local, and (c) usually had offline meetups.

I dont hink doom scrollers are the root cause, but I belive in that we would have a better political debate and better successful politicians if people who spend a lot of time in feeds were aware of the income they generate for platform companies, and how this fuels the attention economy, which in turn amplifies these problems. One of them being: it incentivizes politicians to be populistic in order to be heard through the noise and be successful.

Learning Vim has been one of the highest-longevity skill I picked up in University. With every new technology - autocomplete, IDEs, various GUI design interfaces - there's always a chorus of folks who say: "Well now you don't need to Vim, this new tool makes that obsolete." And every time I end up having to manipulate a mountain of text regardless - whether that's in logs, source code, configuration, or documentation. With the amount of text that AI outputs I don't see the need to manipulate text going away and Vim is one of the fastest and most flexible ways to do that.

I find both chatgpt and Gemini to be very good at writing c++ for Arduino/esp32. Certainly better than me unassisted. Compile errors are very rare, and usually they are just missing declarations. Right now I would say chatgpt is ahead for daily driver use but sometimes Gemini can instantly unlock things that chatgpt is stuck on.

Prediction markets don't uniquely enable it, but they make it far more effective and easy.

Insider trading is illegal. And for trades that aren't technically insider trading, often having some information ahead of time isn't as useful as it seems. Markets are known to react unpredictably to news; sometimes they move the opposite way from what you'd think, especially over the mid-long term, and there are many other influences on the price.

With a prediction market though, if you know what'll happen in the world, you know exactly what you'll win in the market.

Just a few weeks ago, terrorists twice tried to sabotage rail lines in Poland, endangering a passenger train with hundreds of people.

> "[Prime Minister Donald] Tusk said that a military-grade C4 explosive device had been detonated on 15 November at about 21:00 (20:00 GMT) near the village of Mika."

> "The explosion, which happened as a freight train was passing, caused minor damage to a wagon floor. It was captured on CCTV."

> "Tusk said the train driver had not even noticed the incident."

> "A previous attempt to derail a train by placing a steel clamp on the rail had failed, he added."

> "The second act of sabotage, on 17 November, involved a train carrying 475 passengers having to suddenly brake because of damaged railway infrastructure, said Tusk."

Love it!

I might consider adding a little more granularity to the "monthly expenses" part. You already split out medical expenses, which is good. The other big two are housing (mortgage, taxes, insurance, maintenance) and planning for college educations (since it looks like this is for the US.) That last item was an eye-opener for me when I did it 20 years ago (both kids thankfully out of college now...)

In my own planning I also split out "mandatory" (e.g. food, utilities, transport,...) vs. "discretionary" (vacation, hobbies, etc.), not sure if that is a compelling feature though.

Otherwise looks great!
Show HN: Predictability API – An engine to detect drift in AI/Sensors (Numba)
by OGsus | 2026-01-19 18:38:49+00:00
Hey HN,
I'm a solo dev. I built this API to solve a problem I saw in both finance and engineering: Non-Deterministic Data.
Everyone measures accuracy (RMSE), but few measure Predictability (how stable is the variance?).
The engine calculates a 'Predictability Score' (0-100) using a tunable volatility constant (K-Factor).

Tech Stack: Flask, Numba (for speed), Postgres.

Use Case: Detecting sensor drift before failure, or catching AI hallucinations before they hit production.
It's live at https://www.predictability-api.com.
Would love feedback on the math or the API design.

Thanks. Ryan

The LLM output isn't an unfiltered result of an unbiased model. Rather, some texts may be classified high-quality (where the em-dash, curly quotes, a more sophisticated/less-everyday vocabulary are more expected to appear), some low-quality, and some choices are driven by human feedback (aka fine-tuning), either to improve quality (OpenAI employs Kenyans, Kenyan/Nigerian English considered more colonial) or engagement through affirmative/reinforcing responses ("You're absolutely right. Universe is indeed a donut. Want me to write down an abstract? Want me to write down the equations?"). Some nice relevant articles are [1],[2].

> Says who? You can totally do code reuse using manually-written dynamic dispatch in "rust without traits". That's how C does it, and it works just fine.

Rust can monomorphize functions when you pass in types that adhere to specific traits. This is super-handy, because it avoids a bounce through a pointer.

The C++ equivalent would be a templated function call with concept-enforced constraints, which was only well-supported as of C++20 (!!!) and requires you to move your code into a header or module.

Zig can monomorphize with comptime, but the lack of trait-based constraint mechanism means you either write your own constraints by hand with reflection or rely on duck typing.

C doesn't monomorphize at all, unless you count preprocessor hacks.

As a Norwegian, I am genuinely curious how US citizens are reacting to Trump’s letter To Norway and demands.

Setting politics aside for a moment: Is there actual public support in the USA for demanding territory from Denmark? I see polling suggesting that the overwhelming majority of Americans, around 75%, oppose the idea of purchasing or seizing Greenland. It clearly isn't a popular demand among the general public. But do the people who voted for Trump actually back him on this specific issue?

To us in the Nordics, this is baffling. Greenland has been Scandinavian territory since the year 10th century. It was part of the establishment of the nation of Norway in 1261 and remained with Denmark after the Kalmar Union ended. The land has been inhabited by the Thule people and Scandinavians for over a millennium. Yet, the US Government now argues it 'should' belong to the USA and is threatening close NATO allies with tariffs to force a sale.

I am especially curious about the 'Golden Dome' justification. President Trump claims full control of Greenland is 'vital' for this new missile defense shield. Do Americans accept this narrative? From our side of the Atlantic, it looks like a pretext—existing treaties already allow the US to operate the Pituffik Space Base for exactly this kind of defense. Why is annexation suddenly considered 'vital' when the current alliance has worked for decades?

High-profile Republican Senators have publicly called the idea 'absurd' and 'weapons-grade stupid.' How is it, then, that the US Congress and Senate seem unable to stop these threats?

I would appreciate an American perspective: Is this seen as a legitimate foreign policy move or an overreach by the executive branch? Are we just witnessing a train wreck in the making on both sides of the Atlantic, with no option to stop it?

> It is almost impossible to escape the constant barrage of takes and news headlines these days without being a total luddite.

Then I am very proudly one. I don't do TikTok, FB, IG, LinkedIn or any of this crap. I do a bit of NH here and there. I follow a curated list of RSS feeds. And I twice a day look at a curated/grouped list of headlines from around the world, built from a multitude of sources.

Whenever I see a yellow press headline from the German bullshit print medium "BILD" when paying for gas or out shopping, I can't help but smile. That people pay money for that shit is - nowadays - beyond me.

To be fair. This was a long process. And I still regress sometimes. I started my working life at an editorial team for an email portal. Our job was to generate headlines that would stop people from logging in to read their mail and read our crap instead - because ads embedded within content were way better paid than around emails.

So I actually learned the trade. And learned that outrage (or sex) sells. This was some 18 or so years ago - the world changed since then. It became even more flammable. And more people seem to be playing with their matches. I changed - and changed jobs and industries a few times.

So over time I reduced my news intake. And during the pandemic learned to definitely reduce my social media usage - it is just not healthy for my state of mind. Because I am way to easily dopamine addicted and trigger-able. I am a classic xkcd.com/386 case.

Some secular people have values, I don't think religious people are saints. Secular people however don't have a framework to 'force' others with supposed values to adhere to them. I don't believe it's narrow minded to believes changes in religion might have an effect on things, the way people follow their religion is influenced by external factors, don't see why it wouldn't be the other way around as well. Atheists are quite new we'll see what happens.
