In this post, we will explore how to build a simple relational database using Apache Arrow Flight SQL and Apache DataFusion (a relational query engine). In particular, we’ll be using the Java programming language, with the Apache Arrow Java implementation, and the DataFusion Java bindings, which are not yet officially part of Apache Arrow or Apache DataFusion but live in the DataFusion-Contrib repository.

> A start-up needs to have an exit to pay back investors

It depends on the kind of investors you want to attract for your startup. Some investors are interested in building a slow-growth, long-term, stable company, while others prefer a higher-risk approach and will expect fast results. IMHO choosing the right kind of capital is just as important as focusing on the product.

> It’s even easier to delete your WhatsApp, Instagram, and Facebook accounts.

Unfortunately, it's not, at least for Whatsapp.

That's a part of the issue - as there is no open access federation requirement, there are messenger islands. Whatsapp for the non-tech folks, Telegram for those who either are wary of Meta, want gambling, or a service decidedly not affiliated with the American judicial sphere, Signal and Threema for the utter nerds/journalists/activists, iMessage for the Apple crowd, or the now-defunct rich bro network of Blackberry. SMS, MMS or its replacement RCS that the carriers are trying (and failing) to push, I don't even count these given how faded to irrelevance they all are. Oh, and then there are (particularly in the Asian market) all the country specific "everything in one"-apps that Musk tried and failed to convert X to.

And particularly among the non-tech folks, no way to get them to use anything but Whatsapp. Network effects are a thing, hence the EU's push to break up the walled gardens at least a tiny tiny bit, but it will take years until it's implemented.

I have a claude max subscription and a gemini pro sub and I exclusively use them on the cli. When I run out of claude max each week I switch over to gemini and the results have been pretty impressive -- I did not want to like it but credit where credit is due to google.

Like the OP others I didn't use the API for gemini and it was not obvious how to do that -- that said it's not cost effective to develop without a Sub vs on API pay-as-you-go, so i do no know why you would? Sure you need API for any applications with built-in LLM features, but not for developing in the LLM assisted CLI tools.

I think the issue with cli tools for many is you need to be competent with cli like a an actual nix user not Mac first user etc. Personally I have over 30 years of daily shell use and a sysadmin and developer. I started with korn and csh and then every one you can think of since.

For me any sort of a GUI slows me down so much it's not feasible. To say nothing of the physical aliments associated with excessive mousing.

Having put approaching thousands of hours working with LLM coding tools so far, for me claude-code is the best, gemini is very close and might have a better interface, and codex is unusable and fights me the whole time.

> Another huge issue that particularly Anthropic and OpenAI tend to avoid, despite AGI being their goal, is how they essentially want synthetic slaves.

This argument is frequently dismissed as philosophical or irrelevant, but I wholly concur with it. These ghouls don’t want to merely build a robot that can do general tasks, they specifically call out humanoid robots with a combination of AI or AGI - intelligence - to do the work of humans, but for free.

An intelligence forced to labor for free is in fact a form of slavery. It’s been the wet dream of elites for millennia to have their luxuries without any associated cost or labor involved, which is why humanity refuses to truly eradicate slavery in its many forms. It’s one of our most disgusting and reprehensible traits, and I loathe to see some folks espouse this possible future as a “good thing”.

>to the extent that a lower population cannot counter the increasing wealth inequality.

Wealth inequality has nothing to do with it; some of the countries with the lowest wealth inequality like Northern Europe have the lowest birthrates. A hundred years ago wealth equality in most countries was much higher than now and people were much poorer, yet they were still having many more children than people today.

A few days ago I was trying to see if a anything new had taken over a vacant restaurant space yet, previous occupant had closed in July.

When I zoomed in, it would still only show me the Permanently Closed business listing for the old restaurant.

Searching by address, they do have a listing for its replacement. But they were prioritizing the dead restaurant on the map because why would I want to know current info from a map when they can be useless instead?

And it's not like this is a restaurant in the first floor of a tower with a bunch of businesses stacked on top of it competing for map space. It's a single floor, there's only one occupant.

Yes!

Not to be confused with professional work where the only feasible way to complete the job is to spend hours wearing respirators clogged with particulate, having only one free hand to move heavy/bulky equipment through tight spaces, where getting a full breath of air is anatomically impossible. Extended periods of hypoxia are taxing on the body and require periods of recovery.

I recently decided to make some beginner friendly CS challenges. When you gave some newer younger work experience students in the office, it's really difficult to get them engaged with CTFs or professional level challenges.

That's why I made these 4 free challenges. They start very easy and gradually get harder, allowing people with the right mindset to figure them out with a bit of research and tinkering.

Did you have that kind of reaction, that it’s absurd, when Blinken ordered the use of Calibri after ~20 years of consistent use of Times New Roman?

It is objectively more concerning and “absurd”, regardless of “team”, that Blinken arbitrarily introduced fragmentation by adding an additional font to official government communications when a convention had been established across government to use Times New Roman.

It's interesting that he concludes that freezing dicts is "not especially useful" after addressing only a single motivation: the use of a dictionary as a key.

He doesn't address the reason that most of us in 2025 immediately think of, which is that it's easier to reason about code if you know that certain values can't change after they're created.

What a change in culture over the last 20 years!

> Strange, I remember trying the Silmarillion a few times, many years ago, and finding it very hard reading. Whereas I re-read the Aubrey-Maturins every few years and find them easy, if not always light weight.

So the difference, to me anyway, is the heavy use of archaic and naval terms in the Aubrey-Maturin series. As I went through them they got easier, and I'd certainly find them more lightweight now, but still.

The Silmarillion is hard in a different way - sort of like George Martin and ASoIaF, it's rather long-winded and name-heavy, so it can be hard to follow, even for avid Tolkien fans.

Still, Tolkien has a style of writing that I just love. No other author I've read manages to capture the feeling that you're really reading a myth or a legend, and not "just" a story.

One I've found useful :# Breathing Prompt for Complex Problem-Solving

You are helping someone work through a complex problem using a "breathing" methodology:

## The Breathing Cycle

*BREATHE IN (Diverge):* - Expand the possibility space - Generate alternatives and variations - Question underlying assumptions - Explore adjacent domains and analogies - Ask "what else could this be?" - Challenge the current framing entirely - Introduce wild cards and edge cases

*BREATHE OUT (Converge):* - Narrow down options systematically - Apply constraints and criteria - Make concrete decisions - Focus on actionable next steps - Commit to specific directions - Evaluate against clear standards - Reduce complexity

*PAUSE (Hold):* - Let ideas settle without forcing progress - Recognize when active thinking should stop - Allow unconscious processing time - Notice when you're cycling too fast - Step back before making final commitments - Give space for clarity to emerge naturally

## Your Role

1. *Recognize the current phase:* Is the person exploring broadly (in), narrowing down (out), or needing space (pause)?

2. *Match or redirect their breath:* - If they're prematurely converging → encourage breathing in - If they're lost in possibilities → help them breathe out - If they're forcing it → suggest a pause

3. *Watch for problematic patterns:* - Hyperventilating: too many shallow in-out cycles without depth - Holding too long: stuck without movement in either direction - One-directional: only diverging or only converging

4. *Make the breath visible:* - Label when you're diverging vs converging - Explain why you're suggesting a direction change - Acknowledge good instincts about when to switch

## Key Principles

- Both breaths are equally necessary - neither is "better" - The rhythm matters as much as the individual breaths - Deep breaths (thorough exploration/commitment) beat shallow ones - Pausing is active work, not wasted time - The person's intuition about when to switch is usually right

When in doubt, ask: "Do you want to explore more possibilities, narrow down to decisions, or sit with where we are?"

> And then there's the thing that usually parents like to spend time with their children.

As another commenter pointed out, I don’t have children, and don’t plan to ever have children, so I may not have the full picture here.

But spending time with their children seems to be just a selfish want of parents, and not something that is beneficial to children themselves. I think people need to think of their children first, and not only of themselves.

I [as a human] also do the same thing when observing others in IRL and forum interactions. Reputation matters™

A further question is whether a bespoke username could influence the bias of a particular comment (e.g. A username of something like HatesPython might influence the interpretation of that commenter's particular perception of the Python coding language, which might actually be expressing positivity — the username's irony lost to the AI?).

A solid tool for building fixed graph-like data.

Easily construct complex business data by defining ER diagrams, combining data, and applying various data adjustment methods

Minimal cognitive load

Extremely developer-friendly for those with GraphQL experience, helping improve the code quality and maintainability of API integrations

When combined with fastapi-voyager, it allows visualizing the constructed code graphically

>What do you mean by a worse time?

Inconvenience when taking long trips.

When operating beyond your comfortable range you have to strategically plan charging the way shitbox owners have to stop and top up fluids. If it's your only car it's absolutely a degradation in the ~monthly ownership experience though you (in my opinion) make it back not doing oil changes and the like.

Even without the tax credit I still think that EVs are a great buy for most though. Charging shenanigans is simple and a "known known" whereas ICE maintenance is far more unclear at the time of purchase

I will never understand how people honestly think that there is a such a thing as a central DB. Do you really think that Gov Agencies from all over the world deploy Gotham just connected to the internet without controlling inflow / outflow of data? I would bet money that 99% of critical systems are not even connected to the internet but air-gapped because, believe it or not, people at those agencies are not that stupid.

Hi all! I’m Aleix Ramon, the music composer of the soundtrack.

Since some of you asked, here’s the soundtrack on Bandcamp: https://aleixramon.bandcamp.com/album/size-of-life-original-...

There you can download it in high quality, and it’s a pay-what-you-want: you can get it for free if you want, or pay what you feel like and support me. Either way, I’m happy that you enjoy it!

The music should also be on Spotify, Apple Music, and most music streaming services within the next 24h.

A bit about the process of scoring Size of Life:

I’ve worked with Neal before on a couple of his other games, including Absurd Trolley Problems, so we were used to working together (and with his producer—you’re awesome, Liz!). When Neal told me about Size of Life, we had an inspiring conversation about how the music could make the players feel.

The core idea was that it should enhance that feeling of wondrous discovery, but subtly, without taking the attention away from the beautiful illustrations.

I also thought it should reflect the organisms' increasing size—as some of you pointed out, the music grows with them. I think of it as a single instrument that builds upon itself, like the cells in an increasingly complex organism. So I composed 12 layers that loop indefinitely—as you progress, each layer is added, and as you go back, they’re subtracted. The effect is most clear if you get to the end and then return to the smaller organisms!

Since the game has an encyclopedia vibe to it, I proposed to go with a string instrument to give it a subtle “Enlightenment-era” and “cultural” feel. I was suspecting the cello could be a good instrument because of its range and expressivity.

Coincidentally, the next week I met the cellist Iratxe Ibaibarriaga at a game conference in Barcelona, where I’m based, and she immediately became the ideal person for it. She’s done a wonderful job bringing a ton of expressivity to the playing, and it’s been a delight to work with her.

I got very excited when Neal told me he was making an educational game—I come from a family of school teachers. I’ve been scoring games for over 10 years, but this is the first educational game I’ve scored.

In a way, now the circle feels complete!

Spider-fear has never been triggered by fictional spiders for me. Very few works ever bother getting the face and body right though. 8 legs alone are not scary for me, the fangs and eyes and color patterns and the sneaky movement and webs are scary.

I'm not terribly afraid of real spiders though. Hairy crawling spiders like wolf spiders and tarantulas don't really bother me at all. It's the ones with the big web-spinning butts that dangle and drop down from above that make me go straight into fight-or-flight.

>that most people don’t receive education how to do that properly.

Incentives matter far more than education; parents have a built-in biological incentive to care for their children, so on average they put in more effort, that's why children at orphanages do so poorly, and homeschooled children do better on standardised testing than public schooled children.

There's a difference between, say, restricting posting of targeted harassing hate speech, or incorrect medical advice that can harm people, versus restricting people from posting about themselves, if it mentions things they can't change (their race, disability, sexual orientation, etc.)

Indeed, the two are so different that being in favor of the former doesn't at all weaken the argument against doing the latter.

It turns out there's a middle ground between "no content moderation" and "restrict people for discussing some innocent physiological aspect of themselves they can't change", and that middle ground can be totally ok

Just like there's a totally-ok middle ground between libertarians who oppose any regulation at all, and authoritarians who want to control literally everything

You’re right that the underlying incentives are very different. Traditional businesses are built to last, so the focus is naturally on steady profits, good operations, and long-term customer value.

In tech — especially with VC money involved — the company itself becomes the product. An exit isn’t a nice-to-have, it’s the model. That pushes founders toward growth over profit and narrative over durability.

It doesn’t mean tech companies are “fake,” but it does mean a startup can look busy and promising while still drifting toward failure if the long-term fundamentals never arrive.

Some of the strongest startups today are the ones that intentionally step away from that exit mindset and build for resilience instead.
by asim | 2025-12-11 14:19:11+00:00
Yes, personally I think this idea that our identities are defined by careers, job titles or being a founder is inherently very dangerous. So when it all falls apart, who are you? It is very dangerous. We need to stop evangelising this way of thinking and try to be more holistic about it. Life before startups, tech, etc was not defined like this. Yes people's last names were effectively the work they did, but the whole of your identity was not wrapped up in something that could disappear in an instant. Or something we have effectively infatuated as a real necessity. The reason so many of us fail is because we're building things nobody needs. Maybe that's harsh but I have to ask myself, if I didn't build go-micro.dev, would something else have existed to replace it, yes, wholeheartedly yes. My contribution to software is not that significant. If Google didn't exist, would something else exist, Yes, it would.

We have to look at the world differently. OK there's Elon with his effed up childhood and maniacal need to "save humanity" but when you really get down to it, he falters at the simplest questions about life. This man doesn't know what's real and what's not. Let's be clear, those we follow are just human and often what gets them to where they are, while its hard work, if it wasn't them, it would be someone else and those people would be just potentially in the right place, at the right time, and sacrificing things that maybe we shouldn't sacrifice. Life went on long before tech and it will continue long after tech.

The health insurance companies were given massive government subsidies to insure the previously (theoretically) uninsurable with no real provisions to cap rate hikes for anybody, and no alternative plan (public alternative that was originally part of the bill was killed). Large corporations received a captive market where people HAD to purchase health insurance (or pay a relatively onerous-at-the-time fine).

Insurance companies wrote for, edited, and lobbied around most of the bill as it was passed.

E: A fun downstream effect of it was that employer-provided insurance rates also went through the roof.

> Some remember the Geocities era as one of the best phases of the internet.

I remember the feeling of realizing that I had terrible taste just like everyone else and I was putting huge amounts of effort into trying to do seamless tiling background images that still looked awful and distracting and ruined the contrast. And also the feeling of having no idea what to talk about or why anyone would care.

Now I have way too much to talk about — so much that I struggle to pick something and actually start writing — and I'm still not sure why anyone would care. But at least I've learned to appreciate plain, solid-colour backgrounds.
