where nothing is searchable, linkable, or otherwise legible. That's a tradeoff. It has some upsides, but downsides as well.

(granted search has been struggling to not suck in general lately, facebook among others has joined the campaign against legible links, so losses are taking place in web environments anyway)

Even more ridiculous is the number of papers that do not include code. Sure, maybe Google cannot offer an environment to replicate the underlying 1PB dataset, but for mortals, this is rarely a concern.

Even better is when the paper says code will be released after publication, but they cannot be bothered to post it anywhere.

you're limited to one horse at a time with livestock trailer, and if load is a problem, you can use a straight load and i guess remove center divider in a straight load. because i train rather than haul, i'd opt for taking time with load of course.

personal farms don't need to haul, there's no disagreement about that, but op suggested that you can run a horse business this way. it took me a while to realize that he has a vanity farm that's funded by his tech money, so you know he can gradually grow, he doesn't need to board, or train, or any of those other things people in the business diversify their income sources with.

i don't think we're OT at all. in horse business and generally farming you have two types of vehicles relevant to this conversation, trucks and gators. you absolutely need both. your truck can act as a gator, but your gator can't act a truck. you can use pretty much anything as a gator, i've got an old cherokee, an atv with a hitch and an actual gator doing the gator business. op uses a ford focus. the electric pickup from original post is probably a solid gator. kei trucks can be used as gators. but none of this stuff replaces a truck, which you still have to pay shit ton of money for.

usually in conversations like this it's horse people who come in and say "nah we need a truck to haul", but this time op suggested that you can in fact run a horse business with a gator, which prompted some questions from me

Huh, I was going to post the opposite. We have enough enthusiasm and True Believers in tech work, especially in the USA where even PR pieces read "We are so excited to announce..."

We may or may not have enough critics/curmudgeons, but whether they are there or not, they certainly don't seem to rise into leadership roles where they can use their discernment and wisdom to steer better and to stop terrible projects. I know in my company, the top ranks are all filed with beaming excitement and positivity about everything, and everything we are doing is great, and we are so confident in this, and excited about that...

Thankfully, the P-cores are nowhere near as bad as the Pentium 4 was. The Pentium 4 had such a skewed architecture that it was annoyingly frustrating to optimize for. Not only was the branch misprediction penalty long, but all common methods of doing branchless logic like conditional moves were also slow. It also had a slow shifter such that small left shifts were actually faster as sequences of adds, which I hadn't needed to do since the 68000 and 8086. And an annoying L1 cache that had 64K aliasing penalties (guess which popular OS allocates all virtual memory, particularly thread stacks, at 64K alignment.....)

The P-cores have their warts, but are still much more well-rounded than the P4 was.

I used to be like this back when I chronically under-exercised, it was the only thing that would help me sleep. And even then, I struggled with insomnia.

Personally I need 10-20 hours of real sport a week to function really well, which seems to put me in some very high percentiles on HN. I need so much sport that I barely have time to do anything besides work and exercise, which means I don't do many non-athletic hobbies anymore.
Show HN: DevOpsAgent – AI ChatOps for Cloud Deployments
by Alexthh | 2025-04-25 20:18:19+00:00
We built an AI agent that automates DevOps tasks (deployments, infra-as-code, cost optimizations) via chat. It’s like Lovable, but more directed for DevOps, integrated with AWS/GCP/Azure/Linode/Digital Ocean. We’re a small team of ex-[Company] engineers launching a beta – would love feedback or questions!

This is a useful Gedankenexperiment, but I think the replies suggesting that the conclusion is that we should replace Kafka with something new are quiet about what seems obvious to me:

Kafka's biggest strength is the wide and useful ecosystem built on top of it.

It is also a weaknesses, as we have to keep some (but not of all) the design decisions we wouldn't have made had we started from scratch today. Or we could drop backwards compatibility, at the cost of having to recreate the ecosystem we already have.

I managed to find this at least:

The penny drops means sudden understanding or realisation of something or other. The expression usually implies a period of non-comprehension before the penny drops and derives from early penny slot machines in which the coin or coins took quite some time to drop. That is why the expression is sometimes in the form of ‘the penny has finally dropped’. The OED cites the 1940s as the first appearance of the figurative meaning. Penny slot machines first appeared during the mid-19th century and some alternative sources date the current figurative meaning from at least the 1920s, if not earlier.

https://idiomorigins.org/origin/penny-drops

Sounds like your intuition is correct, and the phrase comes in particular from the delay in the penny takes to drop in these machines. I'd imagine if they were faster probably the phrase wouldn't have developed, so an interesting example of how some engineers somewhere who designed the slow mechanism ended up impacting the lexicon.

I kept overestimating how much I was working each day, so I built a simple tool to track only my actual focus time.

It runs in the background and automatically pauses the timer when I open any site or app I’ve marked as a distraction (Twitter, YouTube, etc). There's also a GitHub-style heatmap to visualize your focus over time.

It’s built for macOS and uses a small Chrome extension to detect browser distractions. Still iterating and open to feedback.

Would love to hear your thoughts: what's missing, what would make this more useful for you?

Well, yeah. The filtering is a joke. And, in reality, it's all moot anyways - the whole concept of LLM jailbreaking is mostly just for fun and demonstration. If you actually need an uncensored model, you can just use an uncensored model (many open source ones are available). If you want an API without filtering, many companies offer APIs that perform no filtering.

"AI safety" is security theater.

Just a tangential note to say whenever I see these terms in discussion of MIDI keyboards it reminds me how disappointed I am the vast majority of MIDI controller (and multi-thousand dollar flagship synth) keyboards still don't fully support per note velocity or polyphonic aftertouch. It's only been 40 years kids... (sigh).

We're approaching this issue with humility. (Here is a professionally produced video publicizing the issue and our approach. The issue we're being humble about presupposes that we have achieved a technological advance unprecedented in history.)

We recognize that we'll need to regularly revise our ideas as the field develops. (Despite there being no consensus, we are eager not only to be part of the conversation in the public sphere, but to start it and continue it.)

Hi guys,

Have you ever heard of Photopea, a FREE Photoshop-like image editor?

Yes the genius behind him is Ivan Kutskir. This project of his get:

13M monthly visits

1.5M monthly user hours

$100K monthly ad revenue

Amazingly, he solo-handled 500K daily users and scaled Photopea to $1M+ in revenue and he spends only $700/year for maintenance and keeps all the profit for himself.

I run a Honda Pilot for this reason. With the seats folded I can haul 8’ lumber or 10’ PVC pipe inside the vehicle, no tie down needed. If I need to tow, I have a 5,000LB tow rating so most anything around the property is possible with a good trailer for a couple thousand extra.

I bought reasonably used, spent about 30k instead of 50k+ for a comparable pickup truck which lacks the ability to haul 7-8 passengers when needed.

Also has the benefit of being one of the most “Made in America” vehicles out there, #3 IIRC.

I'd note that he's not subject to them. It's a civilian position, and he's no longer serving in the military. You're obviously allowed to wear makeup as a former soldier.

I agree he's a clown, but not for this. Politicians frequently wear makeup. It's part of the job.

It speculates that peeing in the air may signal the dolphin's health or social status. It must suck to be a loser dolphin who can't signal lest he get ostracized further. Nature is cruel, and this practice, if true, I would imagine, would speed up natural selection. Kind of like if humans would voluntarily share their wealth status. Wait, I guess we do do that.

I worked (briefly) at Apcera as well and on the NATS team as a core contributor on the project. I sympathize because it is really difficult to build a viable business around OSS. But the move to contribute it to CNCF, which put it on a stage that it simply never would have had without the foundation, and now trying to withdraw it because it is still a fledgling project is just not a good look.

The irony is how would this have played out if it _did_ turn into a thriving project under CNCF? In that scenario, the NATS brand would have substantially more value and equity. That would have made a relicensing even more impactful, made it even more difficult to claw back from CNCF, and even more controversial. Because NATS remains relatively niche, I suspect the thinking is that not enough people will really care for it to matter, but if that's the case, why not just make a proprietary fork under a new name?

I don't know how this situation doesn't result in a fork. Either the BSL will be a fork or the OSS will be a fork. But because nearly all of the contributors are Synadia employees, I don't know what this will mean for the longevity of the project.

The issue with this is they claim the cost savings came from not having a screen and other silly features, but that’s not where money is spent.

The real cost savings came a tiny, 150 mile battery. It could easily be <100 miles loaded up after a few years of use, which means there are very few use cases for this truck, and it certainly doesn’t make sense without the tax credit. Cool idea, but there’s no getting around the price of batteries

That's an interesting idea! I'm definitely not a frontend expert, so I'm not sure if it's possible to implement a UI within a bookmarklet. It would also have to be pretty big code-wise to cover all the fallbacks and edge cases. Maybe a hybrid would be an extension that runs things locally, but with the switch I did from hcaptcha to Cloudflare Turnstile the friction seems to be almost gone.

I'm not against this kind of move (Synadia's) by itself, but it seems too early. I've been following NATS for some time, and undeservedly, it hasn't taken off. I could find only two books; documentation is clean but I think it could be improved; blog posts, tutorials, videos are few and sparse in time; community tools are nil (from what I could find). A non-open source license is going to restrict adoption even more.

I recommended it to my clients every time it looked like a solution to the problem, but never been able to convince, due to the lack of community or big cloud sponsorship/offerings.

I'm not going to watch the youboob, but if the title is an accurate summary, I'd say at least DOGE is getting this one thing right... (20.000 monkeys with typewriters may be correct after all)

The cost, and never yet solved problem of all the spent fuel ever used still sitting in "temporary" storage onsite at the reactors, means that nuclear is a disaster that only benefits the corps that get the govt contracts to build the things.

The "gee wiz" and "buck rogers adventure club" members here on HN (who also advocate flying off to Mars for space ranger adventure) may be in favor of this "futuristic" power source, but anyone who's even marginally objective can see that in the current world, spending that money on grid storage will come online and pay off much faster, and not yield tons of radioactive waste (that no one knows what to do with, and nobody wants).

Hi everyone – I’m the founder of DevOps Agent. After years at Ramboll wrestling with sprawling tool-chains and brittle cloud deployments, I saw how early-stage teams waste weeks on manual CI/CD, configuration and cost tuning. So we built an AI-powered DevOps assistant that:

Automates end-to-end deployments From devops deploy --auto to production in minutes: our agent scans your repo (Node.js, Python, Go, etc.), generates Dockerfiles, Helm/Kubernetes manifests and spins up cloud resources on AWS, GCP, Azure, DigitalOcean or Linode—no YAML editing required. Optimizes cost & performance Automatic right-sizing, anomaly detection and cost forecasts help you keep bills under control. Dashboards show CPU, memory, requests/sec and daily spend—real-time and week-over-week comparisons. Enforces security & compliance We bake in best practices: least-privilege IAM policies, vulnerability scans, SOC2/HIPAA/PCI compliance checks and policy guardrails so you can deploy with confidence. ChatOps interface Manage infrastructure through natural language. “Scale my Redis cluster by 2×,” “Show me last week’s CPU usage,” or “Patch that security vulnerability”—all without touching a CLI. We’re in private beta and just opened our waitlist. Would love to hear from folks who:

Struggle with slow release cycles or complex CI/CD setups Want better cost visibility without manual tuning Need built-in security checks but don’t have a dedicated DevOps team If that sounds useful, please join our waiting list: https://devopsagent.dev. I’m really keen on feedback—feature ideas, missing integrations or rough edges you’ve noticed. Thanks!

LLM companies don't agree that using an LLM to answer questions is a stupid thing people ought to face consequences for. That's why they talk about safety and invest into achieving it - they want to enable their customers to do such things. Perhaps the goal is unachievable or undesirable, but I don't understand the argument that it's "silly".

You are totally misunderstanding the point. I am talking about the hypothetical AGI/ASI scenario where ALL jobs are replaced by machines. Not just software development. The economic value of human labour drops to zero. This is not just about me and my own little career. It would impact everyone.

This is a serious topic that is being discussed and debated at a high level. It is an existential threat to human society. It could be catastrophically disruptive. No one knows how it would play out. There could be severe economic inequality and stratification of society unlike anything we have seen in the past.

The primitives and pre-coded kernels provided by CUDA (it solves for the most common scenarios first and foremost) is what's holding things back and in order to get those algorithms and data structures down to the hardware level you need something flexible that can talk directly to the hardware.

I'm not trying to find an attack vector, I'm trying to find a threat model where relying on non-signed commits on master is insecure, but relying on commits signed by the github key is secure.

If you are looking at and trusting github UI/API anyway as part of your verification, then you might as well just look at the green "verified" badge without actually verifying the signature locally. At which point actually signing by the github key is just useless ceremony.

Not the son of a CIA Director, as the title seems to imply.

As a car audio enthusiast, the biggest obstacle to putting a system into a new high-tech car is bypassing the deeply-embedded infotainment system while retaining decent aesthetics and steering wheel controls. The idea of getting an electric drivetrain and new-car safety with a 90's-style blank canvas for audio is amazing.

I hope that the noise isolation and intended speaker mounting locations are good!
