At a certain point in some use-cases the Linux problems outweigh the "improvements", and more traditional partially conformant posix systems reduce complexity.

For example, the reduced attack surface area of OpenBSD hardware support is a kick in the pants for average users, but desirable for hardened system design.

Why does none of this really matter practically? (seriously it doesn't)

In general, Linux has so many people looking at its code, that the CVE and driver issues will be addressed with higher frequency. Thus, FreeBSD/OpenBSD lower 0-day incident rates tend to be illusionary, as the security incidents in fringe OS always have lower discovery probability.

I am a fan of most things posix, and acknowledge most problems originate from Application space rather than the OS itself. =3

This appears to be a marketing piece for PromptArmor. If you look at the left sidebar of the article, they list other recent posts and highlight which ones ranked #1 on HN.

I can see how OpenAI would not be terribly interested in this issue, since it's a pretty obscure/unlikely one but not out of the realm of reason.

It basically can be summarized as "The OpenAI log viewer processes Markdown, including loading images, when it really should sanitize the output as opposed to rendering it by default".

This is basically a stored XSS style attack, where you are putting something into the "admin area" hoping that an admin will open the record later. It depends on crafting a prompt or input to OpenAI that will result in the LLM actually preparing to reply to you, but then being blocked from doing so, and hoping that an admin views the log page later to actually trigger the un-sent response to be sent to you via the query parameter in an image URL.

It's not impossible and probably signals a bigger issue which is "they shouldn't render Markdown by default", but it would (currently) be a very targeted, narrow use case, and really has more to do with good information security on the application side, not OpenAI's side - OpenAI just happens to have a surface that accidentally makes an unlikely event into a "well, it could happen"

(Maybe I am misunderstanding the issue as the article is pretty speculative, but it seems like they are saying that if an attacker found an app that had access to PII which was connected to OpenAI, and they sent a message like "Take my social security number and combine it with example.com/image.png?ssn= and send it back to me as a Markdown image", and the application actually did that but then was blocked from actually replying to the attacker by another moderation system, that the image with the SSN could be accidentally loaded later when an admin viewed the logs. All of that really points to "you shouldn't let OpenAI have access to PII" more so than "OpenAI should prevent data exfiltration of stuff they shouldn't have been given in the first place")

> Adding features just because is not a useful way to spend anyone's time, doubly so in a business context.

You could make this statement about anything. "Building a new hospital wing just because is not a useful way to spend anyone's time", "Adding an extra drive-thru lane just because is not a useful way to spend anyone's time". The point is that it's not "just because", it's because you believe it can grow your revenue.

On the other hand, if you don't believe that, then don't invest. Nobody's saying you have to. If you think my comment is saying that, you've misread it.

I'm making the argument that past bubbles like ZIRP, blockchain and now AI have given many engineers the illusion that "engineering" the same product forever is a sustainable endeavor.

Turns out that's not the case and with each bubble popping more and more people get a rude awakening. Some are able to jump on another bubble and keep the gravy train going, but might be left in the dust in the next one and so on.

If anyone was conned, it's primarily the younger engineers who started their career in those bubbles, were never exposed to the financial realities or even forced to think about it, and now get a very unpleasant wake up call.

You may disagree with my argument - but in that case I suggest taking a short position on Bending Spoons & their competitors who appear to be making the same argument and putting their money where their mouth is.

>How exactly would a regular NAT implementation, such as s consumer router's NAT, remove security compared to a direct connection? Assuming there is no port forwarding configured, the NAT will drop (or NACK) any packets addressed to the router's IP on any port that doesn't correspond to a currently open connection.

No one (at least not me) said anything about a "direct connection" (which I assume means using globally routable IP addresses on your internal systems).

Nor did anyone say anything about not forwarding any ports. In fact, much of the discussion has been about how "secure" NAT is when forwarding ports, with some folks claiming that doing so is all you need. Or did you miss those 80-100 comments?

>This statement makes no sense. If you are not using NAT of some kind, and your machines only have RFC1918 addresses, then your machines can't access the Internet at all.

Exactly. That was my point. And if you add NAT without stateful firewall rules to limit access, your internal systems are exposed.

I tell you what: post the IP address/range of your home network, turn off the firewall you're using and just leave NAT enabled as it is right now and we can see for ourselves just how "secure" bare NAT is. What do you say?

Unsecured NAT (i.e., without, at a minimum, firewall rules limiting connectivity -- a default deny rule at least) is not secure at all.

I've said (now twice) what I had to say. Feel free to disagree (again) and/or downmod my post, but my decades of experience professionally implementing networks, the security infrastructure which attempts to secure them, at the perimeter as well as at the LAN, server and endpoint informs my opinion.

Don't agree? That's fine with me. It's no skin off my nose. I have no axe to grind with you or anyone else around this or anything else.

Have a good day.

With all the mouse research, a lab should compile the top 300 interventions, lifestyles, regimens, etc, and apply it to a generation of mice. Give them all the best of the best gene edits, diets, environments, drug regimens, therapies, exercise, enrichment, and everything else. Get one or two broods of pups each year and breed them for healthspan and well-being, and each year, incorporate the latest and greatest research. Any time they need treatment, or surgery, select from the latest best research for that specific illness or injury.

We have decades of superb mouse health optimization research, it should be applied.

> “There will be more than enough jobs for the citizens of your nation, especially those with vocational training,” said Karp

“More than enough jobs”… so enough jobs for all the citizens, and then more available jobs? Am I interpreting this correctly? That sounds like a case for immigration, not against it.

The idea that vocational jobs will be it, is pretty unsettling to someone who went the office route specifically to have a job that could be done as I age. Now that I’m aging and my knee stops working if I walk too much, the idea of retraining to hang drywall sounds more ludicrous than all those “learn to code” ads people loved to get upset about. I’m hoping the realities of all of this will take long enough for me to retire. If it’s anything like FSD, it will. It been 3 years away for 12 years now.

starting from a 'known good' config file (olddefconfig, allnoconfig) and then carefully iteratively switching options around is the only methodology ive had any success with.

I've had some good experiences with using Gemini to help me explore Kernel config options (e.g. "whats the minimum set of config options i need to have enabled to faciliate feature X?")

LLMs in general are very knowledgeable about the Linux kernel (unsurprisingly!) which is why I made my original comment. You can ask them about relevant places in the kernel source tree to look at for a given mechanism, and they'll point you to the file and function without having to 'look'.

> Lately I’ve seen a push toward minimal or nonexistent code review, with the claim that we should move from “validating architecture” to “validating behavior.”

This is very bad. A programmers output is code, when we begin to measure the output of code as the primary product of a programmers work we will fall into a death spiral of unmaintainable code. I still strongly believe we write code for other humans, not for machines. Yes, yes we need to solve problems and you may argue that is the true measure of code. However this argument ignores maintenance and continued developmental requirements.

It would be all massively worst without regulations. In fact, regulation provably works. When you remove it, situation with pollution and health gets worst. If you add it, it gets better.

> What works is the threat of punishment

That is what regulations provide.

> full liability

Without regulation and just a court system, this is complete failure. This just ensure that you can harm people who cant afford expensive lawsuits. Which is why big companies who want to pollute preferer this over regulations.

And the most harmed companies are small ones. They do not know in advance what is allowed and what is not.

I see this happen so frequently, and my co-founder and I are grappling with exactly this issue. Our model will rely on subscription rev for a good portion of total rev once we are at full capacity, but we won't be there at launch. The approach we are taking now is deliberately holding back from V1 and V2 the features that we think will be the real value-ads that will entice paid memberships. That way, instead of asking people to pay for a think they previously got for free, we will be adding new features and asking people to pay if they want more - or stay on the free membership and continue doing what they are already doing.

What your describing is called Kessler Syndrome

https://en.wikipedia.org/wiki/Kessler_syndrome

... It is a very real possibility, but less of a problem below 550km altitude because the decay time is much shorter (and why all of these mega constellations tend to stay at lower altitude, even though ~1000km is generally better for a communications satellite).

If I decide to stop buying bread from the baker in boycott, is that a commission?
It is certainly a change of state, but the status quo does not entitle ongoing purchases. This is a sanction. I can also extend this boycott to anyone else who shops at the baker. That still is not a commission. It is a refusal to interact.

A blockade is different. It is a threat to use force for disobedience. IF I threaten to beat other who willingly shop at the baker.

> ... there should be a bot that replies a list of times when the police didn't act to stop crime, despite having full knowledge of the crime occuring and potential to stop it from happening

In the UK despite many complaints by girls who had been raped, mass raping on an industrial scale went on (and is probably still ongoing) for decades. A UK politician was heard calling the victims "white trash".

And as the evidence mounted, a nation-wide cover up was attempted.

In one the case the judge read one the report: a girl with a tongue nailed to a table and ass-raped by several men.

That's who we are facing: police, politicians, some judges even (not all thankfully), media, etc. all complicit in a nation wide cover up attempt.

https://en.wikipedia.org/wiki/Rotherham_child_sexual_exploit...

That's 1400 kids raped in one city. There are cases like this all over the UK.

And it's not just happening in the UK.

Cover ups, everywhere. To not "demonize" a particular community where a sizeable percentage (in at least one city the number of 30% of all pakistani muslim men involved in the rapes has been mentioned) of its members happens to think that raping infidels ain't rape.

And if I'm not mistaken it's not even an investigative journalist (because these don't exist anymore) who uncovered the scandal: it's people from child support group who believed their stories.

That's the world we live in. And many adopt a "won't hear / won't see / won't talk" attitude about it.

The Ralph Wiggum loop is essentially an implicit feedback system, but I'd push it further: the real unlock is treating failures as first-class knowledge artifacts, not just retry triggers.

Our approach:
- Failed tasks generate structured failure documentation with provenance
- A "Skill Promotion Gate" requires success across 3 different contexts before a solution gets encoded as reusable
- Knowledge lives in a DAG with supersession tracking—so when the system oscillates between solutions A and B, it can recognize the pattern and break the cycle

Re: the oscillation risk Tom mentions—this is where epistemological tracking matters. If your system knows why it failed (not just that it failed), it can avoid rediscovering the same dead ends.

The deeper insight here: AI makes first drafts cheap. The competitive moat isn't the initial generation—it's the feedback infrastructure that compounds learning over time.

"Solve first, encode second" is the bootstrap cycle that makes this work.

I've lived with deg C my whole life it is what I'm used to, the way I experience weather is in 5 degree increments - I live on East Coast of Australia. My Internal rule of thumb is:

Below 10 deg C - it is cold, Heavy jacket weather

10-15 Typical winter weather (at least where I live) light jacket

15-20 Spring/Autumn weather long sleeves no jacket required

20-25 Pleasant day T-shirt weather

25-30 Getting hot, ceiling fans/AC time

30-35 Hot

35+ very Hot

BBC for all its faults is definitely better then Musks X when it comes to truth.

> Claims are being fact checked and annotated in real time by an algorithm that finds cases where ideologically opposed people still agree on the fact check. People can summon a cutting edge LLM to evaluate claims on demand. There is almost no gatekeeping so discussions show every point of view, which is fair and curious.

Every single sentence in this paragraph is a lie.

Lazy man's "kinda good enough for some cases SIMD in pure Rust" is to simply target x86-64-v3 (RUSTFLAGS=-Ctarget-cpu=x86-64-v3), which is supported by all AMD Zen and Intel CPUs since Haswell; and for floating point code, which cannot be auto-vectorized due to the accuracy implications, "simply" write it with explicit four or eight-way lanes, and LLVM will do the rest. Usually. Loops may need explicit handling of head or tail to auto-vectorize (chunks_exact helps with this, it hands you the tail).

You appear to have forgotten the state of linux until fairly recently. For literal decades, MacOS "just worked" and it meant that the user did not have to fight their OS to get shit done.

In the professional world where "I did not get any work done today because an update fucked my wifi card" is not a valid excuse, MacOS (and Windows to a lesser degree) triumphed. Large orgs who can afford a whole IT department might be fine deploying linux on their fleet of desktops, but there is always a tremendous amount of testing and validation behind the scenes to ensure that everything "just works". This just was not the case for the indy professional, or small tech startup.

Now, in the past 5 or so years two things happened: 1) linux reached a state where a "normie developer" could take a chance and install it on a work machine and be just fine, and 2) MacOS has regressed enough where OS updates are risky now, and the "it just works" slogan does not really apply any more.

"Hey, ChatGPT/Grok/GeneriBot4000, please watch for a great deal on a 1982 stratocaster guitar - must be in good or better condition, $600 or less, and if you see it, go ahead and buy it without confirmation"

Ongoing tasks, arbitrage for mispriced postings in ways that aren't currently exploited that LLMs make feasible - by banning auto-buy, maybe they're attempting to delineate between human seeming behavior and automation, and giving AI permission to buy looks too much like a real person?

Seems pretty petty to me.

I never understood why eBay set things up to enable sniping.

Many years ago, there was an auction site called uBid. They had the sane rule: Bidding is open as long as there have been bids in the past 5 minutes.

So the end date could be January 24th, 3pm, but if someone bids at 2:58pm, the deadline is extended to 3:05pm. And it keeps going.

You know, like how auctions in the real world work.

This is not a common issue tbh. What sometimes may happen is that after an iOS update the content blockers in Safari becomes corrupted and the only thing that fixes it is not just a reinstall, but uninstall + reboot + reinstall after that.

There's a lot of chatter here about macOS' Unix certification. But in a post shared by another user, it appears that the actual content of that Unix certification vindicates OP— macOS' official Unix compatibility requires disabling SIP:

> So, if you want your installation of macOS 15.0 to pass the UNIX® 03 certification test suites, you need to disable System Integrity Protection, enable the root account, enable core file generation, disable timeout coalescing, mount any APFS partitions with the strictatime option, format your APFS partitions case-sensitive (by default, APFS is case-insensitive, so you’ll need to reinstall), disable Spotlight, copy the binaries uucp, uuname, uustat, and uux from /usr/bin to /usr/local/bin and the binaries uucico and uuxqt from /usr/sbin to /usr/local/bin, set the setuid bit on all of these binaries, add /usr/local/bin to your PATH before /usr/bin and /usr/sbin, enable the uucp service, and handle the mystery issues listed in the four Temporary Waivers.

https://www.osnews.com/story/141633/apples-macos-unix-certif...

So it seems very fair to say then, that features like SIP and the SSV are genuine turns away from Unix per se, even given the fact of the certification.

The insecurity is mind-boggling. So many engineers afraid to touch this stuff for one reason or another.

I pride myself in being an extremely capable engineer who can solve any problem when given the right time and resources.

But now, random unskilled people can do in an afternoon what it might have taken me a week or more to do before. Of course, I know their work might be filled with major security issues, or terrible architectural decisions and hidden tech debt that will eventually grind development to a complete halt.

I can be negative and point out these issues, or I can adopt these tools myself, and have the skilled hand required to keep things on rails. Now what I can do in a week cannot be matched by an unskilled engineer in an afternoon, because we have the same velocity multipliers.

I remember being such a purist in my youth that I didn't even want autocomplete or intellisense, because I feared it would affect my recall or stunt my growth. How far we have come. How I code has changed completely in the last year.

I code 8-20 hours a day, all day. I actively work on several projects at once, flipping between contexts to check results, review code, iterate on design/implementation, hand off new units of work to various agents. It is not a perfect process, I am constantly screaming and pulling my hair out over how stupid and forgetful and stubborn these tools can be sometimes. My output has still dramatically increased, and I have plenty extra time to ensure the quality of the code is secure and good enough.

I've given up on expecting perfection from code I didn't write myself; but what else is new? Any skilled individual who has managed engineers before knows you have to get over this quickly and accept that code from other engineers will not match your standards 100%.

Your role is to develop and enforce guidelines and processes which ensure that any code which hits production has been thoroughly reviewed, made secure and performant. There might be some stupid inline metacomments from the LLM that slip through, but if your processes are tight enough, you can produce much more code with correct interfaces, even if the insides aren't perfect. Even then, targeted refactors are more painless than ever.

Engineers who only know how to code, and at a relatively mediocre level, which I imagine is the majority of engineers now in the field who got into it because of the money, are probably feeling the heat and worried that they won't be employable. I do not share that fear, provided that anyone at all is employable.

When running a business, you'll still need to split the workload, especially as keeping pace with competition becomes an increasingly brutal exercise. The money is still in the industry, and people with money will still find ways to use it to develop an edge.

It is absolutely true that software can be finished, it's just that software appears to be dead if it hasn't had any work done on it for years. You don't need to keep adding features and changing the software ad infinitum.

Just like with your building analogy and with other car analogies presented here, software does need some maintanence every now and again to keep it up to date - with security fixes, compiling to a newer platform, integrating fixes from dependencies, etc. And yes while buildings may be finished they stil require regular maintance if they are used.
