Show HN: ClawData – reusable data engineering patterns on top of OpenClaw
by Sean766 | 2026-02-19 23:52:12+00:00
Hi HN,

I build data platforms (Snowflake, dbt, Airflow) and kept seeing the same issue: starting a clean analytics stack is harder than it should be. Not because of tools — but because of patterns.

How do you structure raw vs staging vs analytics layers?
How do you ingest without creating a mess?
How do you avoid rebuilding the same scaffolding every time?

So I pulled the patterns I use into something reusable.

ClawData is a skills library for OpenClaw that encodes practical ingestion and modelling workflows. It’s less about generating SQL and more about enforcing structure.

You can run it locally:

git clone https://github.com/clawdata/clawdata.git
cd clawdata
./setup.sh

It checks for OpenClaw, installs if needed, and lets you select skills (DuckDB, dbt-style modelling, Snowflake patterns, etc.).

It’s early. I’m still figuring out the right abstractions.

Would appreciate feedback — especially on whether encoding data engineering patterns this way makes sense.

Wait, your operating theory on why the NSDAP became popular is because they... tricked everyone into hating jews?

You are not only entirely misunderstanding why the NSDAP appealed to people, you're also completely misunderstanding what post WWI Germany was - a republic hastily brought about with little care so that Woodrow Wilson would offer Germany peace based on his 14 points (he didn't). It was doomed to fail from the very beginning. If not the NSDAP it would have been some other extremists.

The idea that freedom of speech was what led to its downfall does not stand up to even the smallest scrutiny. Or the idea that an aged, pacified 2026 Germany would immediately return to 1930s Nazism if they had free speech is even more ludicrous.

This bill is performative legislature not because of pipes and nails, but because professionally manufactured guns are widespread in the US. Criminals in the US overwhelmingly choose this option.

Criminals have tons of options, including straw purchasing a CA compliant gun, straw purchasing a non-CA-compliant gun from Nevada, or just throwing a brick through the window of the nearest pickup truck with a Glock sticker on it.

Take a look at ZSAs oryx configurator for Voyager (52 keys) - you'll see some general configs and development ones etc.

In general, for my moonlander I would have the first layer with all the normal alpha numerics and a few symbols like <>?

But the second layer would contain most symbols, arranged/grouped in a manner which was natural for programming - e.g. grouping keys together like (), [], {},

Yeah, it’s two or three(?) letters that got cut out, one of them is kinda rare.

You can get used to it, but why suffer. Especially if one also uses a laptop.

Other thing that I don’t like in all these small custom keyboards is that most rely on a single spacebar on one half. I learned to use either thumb depending on which next key is: press space with left thumb if next key is on the right half and vice-versa.

—

Also I would urge you to buy a keyboard with arrows keys and extra stuff like home/end

I use uhk 40 and it is fine most of the time since I use vim-motions in my IDEs. But sometimes I just wish they were there.

For example alt-right on mac is to expand all folders recursively in the Finders list view. Just becomes an effing piano if you need to add caps-l to have an arrow in addition to all the alts and shifts.

You can mitigate this with studd like caps + ; for alt-right arrow (ctrl-right arrow for win), but again, when you need to add shift or not only left/right it gets cumbersome once you are not in the vim-like environment.

tldr; buy uhk 80 nowadays. And a bluetooth external numpad for those days when you need to enter a lot of numbers.

Maybe I'm missing something, but I'm confused why you compared gemini 2.5 against opus 4.6, and gpt 5.3-codex ? I assume you used sonnet 4.5 because 4.6 was released in the last 2 days, but opus 4.6 and 5.3-codex were released 2 weeks ago, so gemini 3 was definitely around then.

Um. Swiping is almost exactly like the gesture letter shapes, except now they are word shapes. Swiping “shape” is always the same gesture on the keyboard, you can learn these gestures and type really fast.

To your second paragraph: of course it looks “throughly 90’s”. It was the 90’s. Did an LLM tell you to say this? I have no idea what scroll bars have to do with anything. I can tell you they were a pain to use. That hasn’t changed.

To your third paragraph: the stylus wasn’t optional. They didn’t just “lack” capacitive screens. It didn’t exist yet at scale. This was what Apple brought to the market. You couldn’t really have them if you wanted them. That being said, I used these interfaces while walking, riding in a car, and sitting still. I never had trouble tapping the right thing because the buttons were huge in the UI.

You do bring up a good point about there not really being swipe gestures to go “back”. I don’t use them today, so I’m not as familiar with that type of behavior other than to say it is really annoying when done by accident, usually while picking up the device.

I know it will not "solve" every case of depression, however, I really wish people who don't already, would try going outside and/or exercising regularly.

Anecdotal I know, but it seems like nearly every person I know who does both are rarely if ever depressed.

While the people I've known who do struggle with depression rarely if ever leave home.

Again, I know this isn't a catch all for all cases, however, I've seen far too many people turn to meds/substances when lifestyle changes could be all that's required.

It's also a couple of things that only have positive side effects as opposed to most of the medicated approaches people take.

I believe we should treat the current administration like the past ones.

If you condemn one president for the actions of ICE, you should condemn all the presidents that used ICE in a similar way.

If you approve of one president for his use of ICE, you should approve of all presidents that have similarly used ICE.

It’s the most logical position, I think.

Define "common-sense gun regulations", because every time someone tries explaining what that means it is almost always the exact opposite of common sense. Is restricting suppressors common sense? Because some of the nations with the most restrictive gun laws advocate for the usage of suppressors. Or bans on the scary AR-15, which is less powerful than most 60 year rifles which nobody cares about, especially when the vast majority of gun crime is committed with handguns. How about bans on gun accessories like types of stocks, slings, or bayonet lugs? How about sawed off shotguns which are less powerful than many "pistols" that shoot rifle rounds? Or shotgun/rifle combinations which were once a popular hunting combination for small game.

Either we should be allowed whatever semi-auto gun, or we should be allowed zero. Everything in between is a complete waste of time and effort and just leads to fucking over poor people for judicial profit because they can't afford $10,000+ lawyer that gets everybody with any money off of such charges.

Excellent science communication, as would be expected from this author.

A recent finding from last year looked at the mutational signatures in colon cancer in those under 50:

https://www.nature.com/articles/s41586-025-09025-8

The different processes that damage DNA have sequence preferences for the direct change in the DNA (e.g. G-->C versus G-->T), as well as the sequence around the damage. Smoking causes very very different signatures of DNA damage than, say, damage from UV from being in the sun.

So every cell in our body carries with it a (noisy) history of the mutagenic processes it has been exposed to.

This paper found some differences in these mutational signatures of later colon cancers, and attributed them to colibactin, a mutagen produced by bacteria.

It remains to be seen what percentage of the increase in under-50 colon cancers this would explain, but it's an additional risk factor that didn't make it onto the chart, likely because it's not coming from standard epidemiological analysis, and instead from the world of molecular analysis.

"Concentration camp” is a term that predates its (somewhat euphemistic, when done in retrospect) use for the camps eventually used in the extermnation campaign by the Nazis (which also started out as concentration camps, in the more usual sense, as part of what was nominally a deportation program.)

Though concentration camps are almost always part of systematic, ethnically-targetted abuse, even when they aren't part of genocide campaigns.

My CS college used Turbo Pascal as a teaching language. I had a professor who told us "don't turn the range and overflow checking off, even when compiling for production". That turned out to be very wise advice, IMHO. Too bad C and C++ compiler/language designers never got that message. So much wasted to save that less than 1% performance gain.

I fled SF and I know a bunch of similar people. Startups are still founded there for the address, not the local talent pool. The address is there because of inertia, not because of inherent advantage. If I were to create a startup I wouldn't even consider doing it in SF now. It is a waste of money that could be put towards the idea. The US is clearly on an ant-intellectual path. People default to here because of inertia but every attack on immigrants, every high level decision based on quack science and personal gain and every attack on our institutions supporting the development of the next generation is putting inertia elsewhere. It is clear as day that the US is only keeping any kind of advantage right now due to inertia and threat and not innovation and effort.

Creator here. We just shipped MCP Registry support — pip install semanticapi-mcp gives Claude Desktop native access.

Also shipped auto-discovery today: query for an API we don't have indexed, it gets discovered in real-time from the provider's docs.

The semantic matching runs ~100ms (vector similarity → LLM confirmation). 163 providers, 771 capabilities built in.

Happy to answer questions.
Show HN: Stack Status – Tracking outages across the internet's underlying stack
by thestackfox | 2026-02-19 23:57:51+00:00
I built a dashboard to track incidents across the services the internet quietly relies on: stackfox.co/stack-status

Web apps feel flakier lately because the stacks underneath keep getting taller. When one layer blips (auth, hosting, DBaaS, queues), everything above it starts failing.

Stack Status pulls outages from major infra providers and shows what’s actually down right now.

Early version — feedback on missing providers or categories is welcome.

They didn't claim evolution got it perfectly right.

They speculated that immune systems evolved to avoid being continuously on alert. And that's exactly right- our immune systems have an extremely complicated system for detecting foreign invaders that is tightly regulated. And a failure to regulate that is often associated with autoimmune disorders, which remain very poorly understood.

I've studied biology from the perspective of engineering better drugs for decades now and I can say with confidence that I simply don't understand how the immune system works, and I don't think anybody else really does either (compared to, say, the heart, or many biological systems like protein production). We have identified many players, and observed a great deal of actions, and have speculative models for many of the underlying processes, but we don't really have an "understanding" of the immune system. I skimmed this paper and frankly, it has a very long way to go before people are convinced to try this in human clinical trials.

I look forward to innovations, but to a first order approximation: evolution found model parameters that exceed the best human science and engineering.

Even as the field evolves, the phoning home telemetry of closed models creates a centralized intelligence monopoly. If open source atrophies, we lose the public square of architectural and design reasoning, the decision graph that is often just as important as the code. The labs won't just pick up new patterns; they will define them, effectively becoming the high priests of a new closed-loop ecosystem.

However, the risk isn't just a loss of "truth," but model collapse. Without the divergent, creative, and often weird contributions of open-source humans, AI risks stagnating into a linear combination of its own previous outputs. In the long run, killing the commons doesn't just make the labs powerful. It might make the technology itself hit a ceiling because it's no longer being fed novel human problem-solving at scale.

Humans will likely continue to drive consensus building around standards. The governance and reliability benefits of open source should grow in value in an AI-codes-it-first world.

There's a ground truth to human cognition in that we have to feed ourselves and survive. We have to interact with others, reap the results of those interactions, and adjust for the next time. This requires validation layers. If you don't see them, it's because they're so intrinsic to you that you can't see them.

You're just indulging in sort of idle cynical judgement of people. To lie well even takes careful truthful evaluation of the possible effects of that lie and the likelihood and consequences of being caught. If you yourself claim to have observed a lie, and can verify that it was a lie, then you understand a truth; you're confounding truthfulness with honesty.

So that's the (obvious) distinction. A distributed algorithm that predicts likely strings of words doesn't do any of that, and doesn't have any concerns or consequences. It doesn't exist at all (even if calculation is existence - maybe we're all reductively just calculators, right?) after your query has run. You have to save a context and feed it back into an algorithm that hasn't changed an iota from when you ran it the last time. There's no capacity to evaluate anything.

You'll know we're getting closer to the fantasy abstract AI of your imagination when a system gets more out of the second time it trains on the same book than it did the first time.

I have both a ZSA Moonlander and Voyager. I've used the former for five years or so, and the latter as a travel keyboard for about a year. I'm super happy with them (obviously happy enough to buy a travel version).

I switched to Dvorak at the same time that I switched from row staggered keyboards (so five years ago), and I must say, if you're thinking about switching layouts like that, there is no better time than when switching to a wildly different keyboard. My Dvorak muscle memory is entirely tied to typing on a split, columnar keyboard, and my QWERTY muscle memory is entirely tied to row staggered keyboards. I have never used Dvorak on a row staggered keyboard, and I have never used QWERTY on my Moonlander or Voyager. I think that's helped with maintaining my ability to use standard QWERTY keyboards after not using them regularly for years.

Suppose you're an Iranian citizen with video of milita murdering your countrymen, and you have no way to upload it (even suppose you have a starlink, but you're concerned using it will get you tracked and killed). Wouldn't Freedom.gov be a very, very good thing in that set of circumstances? (provided Iran haven't blocked access to it, in which case it's useless, but that would make you no worse off than if freedom.gov didn't exist).

Probably not a great suggestion these days. Back when I first got carpal tunnel / RSI (1995), I was using an IBM model M - which I loved the feel of. I had a dream of cutting a keyboard in two and hanging two halves off my chair so I could drop my arms to my sides and type that way.

Anyway, after trying a couple of things, Microsoft Natural (the original with backtilt) saved my programming career. I still have "weak" wrists/fingers/forearms, but it's rarely painful enough for me to have to stop working. Adding in some stretches generally makes it so I can survive.

I can type on a normal keyboard for maybe 15 minutes and maybe an hour on a laptop before I just can't anymore. I can generally go most of the day on my Microsoft Natural. Retraining from a regular keyboard layout (took typing in high school - yes, I'm ancient) wasn't hard at all - it's basically the same.

Sure, it's technically not a "split" keyboard - it's still one thing. These days, I buy used examples off ebay, usually 3 at a time, and on some, the typing action is horrible - but I still have a couple of examples that are usable. And I had to find the right ps2->usb adapters for my work setup. If I ever totally run out, my professional coding days are probably done.

Even if you don't want to go through the trouble of setting up dockerized containers/VM, I'm always shocked when I see people using Codex/CC on their primary user account which usu. has admin privileges.

At least take the time to setup a more restricted agentic user account to limit some of the fallout damage in the event of a disaster.

> The US government is now more authoritarian than the Chinese government

Nah we’re not playing this game.

Try asking the CCP officials in person about Uyghur internment camps, or Tiananmen Square, and see if your family isn’t all arrested.

Ask Olympian Alysa Liu how the CCP targeted her father to try to coerce her to skate for China.

China is trying. Around the time the US announced restrictions on the H-1B visa, China announced the K visa for attracting immigrants [1].

At this point in time, I don't think people are lining up to get K visa to go live in China. But if the current trajectory continues in the US, who knows how things will be in 5 years?

From the country where guns are sold? I don't get it. What is the point?
Not even being ironic. I don't understand the point.

If you tell me that this can make an untracked weapon, I will tell you that probably an untracked weapon can be done with anything, and surprise surprise, even without 3d printed parts.

Imagine the amount of false positives and inquiries on unprovable things.
Soon this will also be used for copyright or whatever, and that will be the sole purpose

To be fair, there is a decent chance that law would be deemed unconstitutional in federal court. The only problem is nobody making their own guns at home has the capital to try and bring this case to any larger court. The ones with capital to do so, established gun manufacturers, have no incentive to fight it, a couple hundred bucks is literally nothing to them. They spend more money on office coffee each day.

Doesn't the law include that devices which fail to implement such checks are barred from sale?

>In addition, knowingly disabling or circumventing the blocking software is a misdemeanor.

The inobvious thing is that that aspect of the law cannot be applied to felons or persons convicted of misdemeanor domestic violence, since like failing to pay the tax stamp on a Class-III firearm or accessory, it would require self-incrimination, which thus far, is still illegal.

I'm not so sure - everyone goes on about the EU's relative lack of GDP growth as though it's a death sentence, which is obvious hyperbole.

In any case, numerically I'd imagine that 15% being made up by spending increasing by 2-3 times by the remaining 85% (from 2% previous target to 5%, or 3.5% more realistically).
