dkobia··on Meta Blocks President Lula's Facebook Page, Campaign Ads 2 Weeks from Election
No one used to care about elections in other countries, but it seems political polarization is truly globalized now. An election in one country seems to carry such heavy stakes for citizens elsewhere. Why? Transnational disinformation? Sad time.
dkobia··on Rails World 2026 Opening Keynote [video]
A few things are true:

- He is not wrong and all programmers need to hear this

- He loves to hear himself talk

- A year or two from now he will run this video to admit he was wrong about something

dkobia··on What AI-Native Looks Like
13,000 tests. That tells you everything you need to know. It doesn't matter how experienced you say you are, if AI is doing all the work including writing and running tests because I know no human is actually reviewing these. I've recently found tests written by Fable that don't actually do anything in a very large codebase. My point is not to advocate for doing any of this manually, but to highlight one of the problems brought about by pumping out so much code.

I hate to sound cynical, but I don't know if bragging about being AI-native is something any of us should be doing. We're really just pulling a lever on a slot machine and crossing our fingers.

dkobia··on Flock is rolling out a voluntary severance program
Axon which is already well established is quietly stealing Flocks market share while avoiding all the scrutiny.
dkobia··on Senate Blocks Cryptocurrency Regulation
Ordinarily regulation is favored by liberals and opposed by conservatives. This particular regulation flips that dynamic. As they say -- Follow the money. The exchanges want it so they don't have to deal with the SEC any more. The president wants it, mostly because it validates World Liberty Financial, meme coins, and the questionable money made ($500 million in reported revenue).
dkobia··on I Used AWS Cognito for a Startup. I Wouldn't Do It Again
I both hate and love Cognito. Hate it for its unnecessary complexity, love it for providing auth at bargain bin prices. I review Auth0 contracts frequently and that is daylight robbery/extortion, a poster child for vendor-lock-in. I had hopes for clerk.dev, but unfortunately the auth business optimizes for deep lock-in + steadily escalating prices.

After working through a few transitions to/from Auth0 that is something I never ever want to do again at scale.

dkobia··on Africans Are Turning to Starlink
Worth remembering that many African telcos are not just mobile phone/data providers but also digital wallets (mobile money) - much of the GDP flows through them. Companies like Safaricom are the de facto financial utility of the country, so they are not going anywhere any time soon. That said Starlink is forcing the telcos to innovate and expand footprints. They’ve held very comfortable politically protected monopolies for far too long.
dkobia··on ICE Appears to Be Buying Immigrants' Tax Identifiers from a Data Broker
The open secret here is that we have a system that collects billions (~$100 billion annually[1]) in unclaimable taxes while keeping the labor force just vulnerable enough to stay cheap. That said, ICE's actions seem like self sabotage.

dkobia··on AI is slowing down
Zitron is begging for a collapse at this point. Yes, his macro analysis correctly identifies a massive financial risk but his incessant pessimism completely misses the incredible ground-level utility that many of us on HN celebrate every day through undeniable, massive productivity gains.

At this point I'm trying to believe there's a middle ground where the level of individual capability this unlocks, leads to major discoveries.

dkobia··on Project Hail Mary – Stellar Navigation Chart
Thank you for making this whoever you are. There is a wonderful video at https://www.youtube.com/watch?v=8FT-oz9aZU4 that visualizes space travel and time dilation in Hail Mary. What I wished I had immediately after watching it was an interactive stellar chart.
dkobia··on I believe there are entire companies right now under AI psychosis
The primary issue here is that CEOs and investors are particularly vulnerable to AI psychosis which is then forcibly propagated to the rest of the organization. Understandably, the perceived benefits are almost impossible to ignore, compounded by the FOMO of the AI first/AI native narrative being sold by AI influencers.
dkobia··on Air is full of DNA
This always blows my mind. We are currently breathing in the DNA of the trees, animals, and people around us—and we’re leaving ours behind for them, too. We’re all one big genetic soup.
dkobia··on All phones sold in the EU to have replaceable batteries from 2027
It seems like the whole world could massively benefit from this much like the other great innovation out of the EU -- the Common Charger Directive (aka USB-C).
dkobia··on Ask HN: M5 MacBook Pro buyers, worth spending the $$$ to maybe run LLMs local?
I’m running local models with a maxed out M4 but I find local models only useful and reliable for trivial tasks and sensitive items like database optimization work. Local LLMs just don’t come anywhere close to Claude or Codex for heavy work.
dkobia··on A Tiny Camera Revealed a Hidden Passage in the Great Pyramid
Just when you think Egyptology can't get more interesting, it does. No wonder "just a quick search about the Pyramids" turns into a lifelong obsession for many.
dkobia··on Elon Musk pushes out more xAI founders as AI coding effort falters
I thought Grok in the car was awesome until it went off on a tangent and started praising Elon.
dkobia··on Tesla Sales Down 55% UK, 58% Spain, 59% Germany, 81% Netherlands, 93% Norway
The average price of a new car in the US is now ~$50,000 and the average monthly payment is almost $800. All people want is an affordable car and it is clear that won’t happen any time soon. It isn’t strange at all that prisoners to this system are cheering on the Chinese disruption.
dkobia··on America Isn't Ready for What AI Will Do to Jobs
AI Slop or not, these doomer articles have more than a grain of truth and you as a knowledge worker knows “Something is happening”.
dkobia··on I now assume that all ads on Apple news are scams
Surely what they make from these ads is negligible enough to not warrant the terrible user experience for something users pay for. The ads in Apple News are infuriating.
dkobia··on Dell UltraSharp 52 Thunderbolt Hub Monitor
At 52" I now believe that there is a limit to the size of a monitor. This might have crossed it.
dkobia··on Let's be honest, Generative AI isn't going all that well
Preaching to the wrong choir. The HN community is reaping massive benefits from generative AI.
dkobia··on How AI labs are solving the power problem
Interesting choice of names: "Solar Turbines" - a wholly owned Caterpillar subsidiary that designs and manufactures industrial gas turbines.

That said, it is all pretty impressive.

dkobia··on AI is wiping out entry-level tech jobs, leaving graduates stranded
I had the privilege of working with a great SWE intern this year. Their fresh ideas and strong work ethic made a real impact. Experienced engineers need this kind of energy.

Yes many over-rely on LLMs, but new engineers see possibilities we've stopped noticing and ask the questions we've stopped asking. Experience is invaluable, but it can quietly calcify into 'this is just how things are done.'

dkobia··on Australia begins enforcing world-first teen social media ban
I have kids and I like this but as we know, prohibition only makes the drink stronger and the thirst deeper.
dkobia··on It's ~2026 –. ChatGPT still doesn't allow email change
This is probably one of those tickets on the backlog that is constantly kicked down the road. Always superseded by a new fire.
dkobia··on Tesla is at risk of losing subsidies in Korea over widespread battery failures
Besides being a meme stock, Tesla is also in the enviable position of owning its entire stack - software, hardware, chips, manufacturing etc., unlike Honda that has many critical components built by other manufacturers and not tightly integrated with the software. It is therefore well placed to make much more revenue per vehicle, if only the owner of the company can get out of its way.
dkobia··on Apple Shelves Vision Headset Revamp to Prioritize Meta-Like AI Glasses
For me - hands free operation. I love to use them at my kids games and events. Many times parents are trying to both watch and capture that special moment and fail at both. The LLM has so much potential but hobbled by the fact that it is supported by Llama.
dkobia··on Apple Shelves Vision Headset Revamp to Prioritize Meta-Like AI Glasses
Meta is onto something pretty remarkable. The only problem with their glasses is that they’re built by Meta.
dkobia··on Xcode Is the Worst Piece of Professional Software I Have Ever Used
Swift is actually a really good language let down by its official IDE. Slow build times, laggy autocomplete, random crashes etc. I can’t remember Xcode ever being great to use.
dkobia··on Bringing fully autonomous rides to Nashville, in partnership with Lyft
What a time to be alive. 3 companies competing for what might be the next trillion dollar business.

- Waymo has the advantage of launching sooner but has much more expensive vehicles which will eat into margins.

- Tesla has the advantage of full vertical integration owns their hardware and cheaper cars but also trying to do this with vision only.

- Zoox has the advantage of building purpose-built autonomous vehicles from the ground up with Amazon's deep pockets behind them, but faces the challenge of manufacturing at scale for a novel vehicle.
