| 3 | Re: Postgres 19 is late because so many more bugs are being found now
This is a good thing. Repaying technical debt is always a great thing.
On our own 1.5M loc system, we've found and fixed thousands of bugs, security holes and circular dependencies in the last year. Code quality has increased, test coverage increased. We've also recently set our compiler to treat warnings as errors, and to be as strict as possible. It is absolutely amazing to see the gaps being filled, it would've been an impossible task for human devs and IDE's would've made it very uncomfortable. We've also ironed out all the bugs and failure modes in our infrastructure automation / monitoring. Our next project is to eliminate all 3rd party dependencies, and after that to rebuild our frontends completely using zero frameworks, not touching npm ever again after that.
So when I read this about postgres, I was very happy that they found and pursued this side quest. They can make the codebase bullet proof.

| 4 | Re: Ask HN: Which TV do you recommend for privacy?
- Buy an LG OLED TV. They're as gorgeous as they are notorious. I just got a 77" LG C6 and it is crazy good.
- Root it [0].
- Install Glasshouse [1] and disable all telemetry. YOU now own the glass. Now you can chromecast to the TV, use Adfree YouTube, access IP TV, etc etc etc. No point crippling your TV by pulling the wireless module and voiding your warranty.
- Install a bunch of cool apps to your TV [2] (there are many more out there besides those listed here)
- Restore to Factory Defaults if you ever want / need to unroot and get back to stock e.g. a warranty claim
The only issue is that LG recently closed the vulnerability that made rooting possible so you don't want any firmware released after 2026-10-10 like 43.21.84. Hopefully a new exploit is found that makes rooting possible once again.
BTW, you might have heard of Dev Mode on these TVs but they don't allow anywhere near the functionality that rooting provides.

| 6 | Re: Postgres 19 is late because so many more bugs are being found now
I did a little AI-assisted bug-hunting in Postgres this summer in between jobs, and the haul was staggering. Multiple serialization anomalies (eg [0] [1] [2]), foreign key integrity issues ([3] [4]), planner correctness bugs such as [5]. Various CVE-worthy vulnerabilities. An unfixable timezone bug [6]. The list got so long that I had to triage what I even had time to report, and settled for a dozen or two out of hundreds of candidates. Now imagine the entire world doing this.
[0] Write skew observed under serializable isolation:
https://www.postgresql.org/message-id/flat/CA+COZaBo+ZpKgMvx...
[1] Serializable anomaly: duplicate primary keys:
https://www.postgresql.org/message-id/flat/CA+COZaBOiiRPmEfX...
[2] SERIALIZABLE can commit write skew after SSI summarization:
https://www.postgresql.org/message-id/flat/CA+COZaCtK=UQbeQw...
[3] Fix temporal foreign key validation of pre-existing rows
https://www.postgresql.org/message-id/flat/CA+COZaChq_ukm2o7...
[4] Lost lock during toasting allows FK violation
https://www.postgresql.org/message-id/flat/CA+COZaC-2-GQabq+...
[5] Partition pruning can incorrectly exclude a RANGE default partition
https://www.postgresql.org/message-id/flat/CA+COZaDXrfTaBjLE...
[6] timestamp vs. timestamptz comparisons inconsistently ordered under DST : https://www.postgresql.org/message-id/flat/c22286ad6268347c6...

| 7 | Re: Postgres 19 is late because so many more bugs are being found now
> This year is going to be different. PostgreSQL 19 most likely won’t be released until November… […] So, what happened? The short answer is that LLMs happened. […] There’s a huge amount of code, and that code contains a huge number of bugs. […] What’s different now is that it’s become vastly easier to find those bugs.
This seems…good?
That it might disrupt the project's "traditional" release cadence a bit doesn't seem terribly bad in light of the alternative, which is shipping another major update with bugs which have apparently haunted the codebase for some time.

| 8 | Re: One-minute frequency disturbances from synchronization in power systems
The corresponding concept in gears is to avoid meshing two gears unless the number of teeth are co-prime, because this will cause uneven wear patterns. If the tooth counts are coprime, then each tooth will contact every tooth on the other gear the same number of times, effectively "wear leveling" the teeth.
In this instance, one fix is to fire the timer every 59.XXX seconds, so it will naturally drift out of phase with the minute hand of the clock.
If work needs to be done exactly every 60 seconds, this is fixed by having a WAIT(RAND(60e6)) microseconds during the first timer initialization, so if 10,000 units start simultaneously they don't try all at once. This is good practice in most (all?) systems. Hint: test power and infra outage/reconnect, which can unintentionally sync timers.
This is why many software will do automated updates every 17 hours: 17 is coprime with 24.
Classic "thundering herd" mitigation tactics.
Edit: Tempting to blame IoT, but (since this is news) I don't think anyone knew there was something to fix here. We have the tools however.

| 9 | Re: AI delivers 'zero financial payoff' to most companies, Apollo economist says
The same Apollo Global Research partner, Torsten Slok, also published this widely cited story in September 2025 last year, "AI Adoption Rate Trending Down for Large Companies": https://www.apolloacademy.com/ai-adoption-rate-trending-down...
I don't think that one has held up very well. A cynic might opine that they've realized how easy it is to grab headlines and attention by putting out research that feeds people who are hungry for negative stories about AI.
UPDATE: I'm going to take this one back a a bit: it turns out Apollo publish articles like this on a daily basis, so the occasional headline that appeals to the "hungry for negative stories about AI" crowd is less of a pattern than if they published less frequently than that.

| 10 | Re: Frontier Airlines Likely Breached
Someone found a vulnerability in the system of Hong Kong Airlines that let the user to see the details of another passenger by changing a few characters in the URL. He reported the issue to the airlines. Then he was prosecuted and found guilty for hacking.
Tells you a lot about the attitude of many cooperations about these vulnerabilities.

| 11 | Re: Landline phones will switch off across Britland in 100 days, no extensions
An interesting component of the switching off of POTS is that the quality of service requirements are different. POTS is regulated to require the phone company to maintain a certain legal quality of service with negative consequences for failing to do so.
Meanwhile, cell phone and VOIP services are "best effort."
The phone company put a pretty huge amount of effort into maintaining QoS (Lily Tomlin jokes aside) because there were consequences for not doing so. It makes sense that they would prefer to shed that responsibility.

| 13 | Re: ChatGPT and Codex usage limits merging
It's amusing how desensitized we became to AI companies charging money however they like.
Just look at this announcement: "your usage will be measured in tokens, which we do not define, nor give you a way to measure them. The amount of tokens you consume will depend on things you can't control". What is left unsaid is that your subscription will contain an unknown number of those tokens you can't measure anyway, and that they will change the number whenever they feel like it.
You pay for… what, exactly?
I have no idea how this kind of sale is legal, especially in jurisdictions with consumer rights protection (EU).

| 14 | Re: Mathematics has changed. Let's act like it
> To me, someone who chooses a worthwhile problem, obtains a proof completely using AI, understands it thoroughly, and uses it to develop interesting further questions or directions has made a substantial mathematical contribution. I would give that person substantial credit even if they supplied no new ingredient in the original proof.
Yup. This is what Terence Tao has been saying about digestion of results for several months now. Mathematics has become a field where results themselves matter less, the social aspect of attracting others to understand your results and explore new problems has become more important.
In a sense it is a little
bit like software engineering, where writing code can sometimes be delegated to AI, and is arguably less important than understanding what the customer really wants from this software.

| 15 | Re: Serbia just elected the world's brainiest parliament
I feel most comments in this thread do not really understand what Vućiċ regime was.
Google Aleksandar Vućiċ Voja Nevolja meat grinder…
Vučiċ is successor of people that assassinated Zoran Ðinďić, a Serbian prime minister. Basically drugs and arms dealers from either mafia, secret service or special forces.
Even if this government ends up being corrupt the level of moral lows they would need to hit to reach previous regime is staggering.
So people justifiably think it can’t get worse… but that only the time will tell…

| 16 | Re: Jepsen: ParticleDB 1.1.4
> We now run sustained Jepsen workloads daily alongside our own test suites.
Why would anyone believe you when you say this? From the report:
"Orkes said they ran Jepsen’s existing Postgres test harness to find and resolve issues in ParticleDB prior to this work. However, that same test harness failed immediately when run against ParticleDB 1.1.4. Orkes also stated they tested ParticleDB with SQLancer, which generates far more complex queries than the ones we tested. It is therefore perplexing that nearly every feature we tested exhibited glaring errors, and that our findings seemed to come as a surprise.
Most databases have a test suite which exercises at least basic examples of each feature, and it is customary to run those tests before release, if not continuously. Where were those tests for ParticleDB? How does one add support for NOT NULL constraints without a test which tries to insert at least one NULL value? What development process adds a CHARACTER(10) type without trying to write a string of (e.g.) five characters?
Our findings suggest structural deficiencies in the ParticleDB QA process. Perhaps tests were not run prior to release. Perhaps the test suite was run, but failed to exercise basic functionality. Perhaps engineers entrusted Large Language Models with the work of testing."

These guys are no fun at all.
Is this really the same cowboys that recklessly broke into others networks and instead of apologising proudly told the world how they did it?
Every 6 months Anthropic publishes a report telling us how closer they have gotten us to extinction as if human life was just a game, yet now they draw the line at computer game modding??

I find it fairly amazing that they could say this without mentioning the episode "The measure of a man" in which Picard literally makes the case.
Perhaps it is uncomfortable for people to think about now.

| 19 | Re: Anthropic may not secure investment-grade rating after IPO, Blackstone says
ChatGPT became publicly available in November 2022, and Claude followed in March 2023. It's year 4. It's foolish to think we know who the big names will be 20 years down the line, which is the kind of timeline bond investors are thinking about. A lot of people probably wish they could have invested (or invested more) in Google or Facebook in 2006, but they are probably very glad they did not invest in Yahoo or MySpace (or Friendster or Tumblr .. you get the idea) at the time, despite looking very promising (MySpace was beating Google on pageviews on some days in '06 and '07). Instagram and Snapchat and TikTok and WeChat didn't even exist yet.
