It's such a wild tale. What a wonder-land setup; this amazing research firm that so cyclically pulls in interesting projects and uses that to pull in interesting people which helps it get more interesting projects. What a whole different world that feels like!

> Not assigning this systems engineering-style contract to an academic department makes sense. Most academic departments are just not staffed and structured in a way to make projects like this feasible. But it’s unclear how an outfit like Raytheon would have done working through problems like the one described above. Would they have been able to solve them? If so, how quickly?

What a set of ideas to obsess over (at least to me)! The initial arpanet contract was for equivalent of $8m. Big players were mostly no-bidding it.

I wish tech had more people asking for outlandish bat shit wild stuff, stuff we don't even know if we can do. But just as much, I guess what's equally crazy is that this was kind of just one ask: it happened to be an extremely good ask, opened up so many further frontiers for exploration. We can come up with absurd abstract problems & challenges, but which problems are abstract enough to be get new inquiries after? What expands thought-spaces as we work it?
How are you going to sink/take out Houthi-like troops with lasers once you approach enemy shores? Taking those people out with missiles is already too expensive and a losing game going forward.
Show HN: LangCSS, the AI Assistant for Tailwind
Hi Everyone,

This is very early preview of an idea I am working on.

The idea is to help you do designs using AI, outputting tailwind classes.

I think tailwind is particularly suited because you can usually "drop in" the styles created here into a bigger tailwind project no problems, whereas with regular CSS you might be "fighting" the CSS sheets, especially if they are semantically defined (e.g. input has styling rather than .input).

For a link to try this out, at the moment there is no login system or security, just go to https://langcss.com/app - if I get too much traffic I might need to turn it off! The posted links is kind of the "sale pitch" and you can add your email if you want to follow how it is going, but no need to if you don't want to.

It is basic, it is one of those much frowned upon "OpenAI wrappers" :-) but I intend to do more over time. For example give it knowledge of many free components, allow more collaboration with an online editor so you can make tweaks, then get the AI to iterate on that, and convert HTML to React, Vue etc. (using non-AI compilers).

I have been dogfooding this, and it help me design the home page logo, and many of the elements there. The footer was wholesale taken from the AI output.

I… I’ve been building a plant app too and it took me waaaay too long to confirm that this app is indeed for house plant and not factories. The readme is a good setup guide, but I think a clearer/more engaging feature list would go a long way. Also, as others mentioned, examples in the form of screenshots or videos would be very valuable.

Will come back to this in a bit if I remember, seems like a very capable complex system! I would love something that lets me track everything I want to about my plants with minimal overhead.

I agree that this method will produce a better estimate of expected mean real world performance under certain load conditions, but still contend it just muddies the waters about which solution is in fact the fastest.

Aerospace was my field before tech was. Reliability is still my field.

A door got sucked out of a plane in flight. That is not a matter of unavoidable human error but can only be the consequence of a concert of cascading failures of the type that should never happen which is why it’s a 10/10, if the flight had been full at least one passenger would have likely been sucked out. It is dumb luck that this did not happen.

Your attitude of derating a disaster like this is a strong indicator of the type of problem in the industry. In the end if we don’t get executives resigning and major operating overhauls with the responsible entities, it will be a terrible miscarriage of justice.
>I think abstraction is good in theory, but at the end of the day the implementation is what is happening.

Abstraction is absolutely necessary in practice. It's the language we use to tell a system what we want it to achieve. It's the only way for us to know what the system can do without starting a science project. It's the only way for the implementer to know what to implement. And it's the only way to check whether a system actually does what it's supposed to do.

Of course, knowing how a system actually works is always better than not knowing it. Every abstraction is leaky as so many side-channel attacks clearly demonstrate. But that doesn't mean the abstraction is some theoretical pie in the sky that we can live without.
I will remark that, excluding cases where some idiot is offering several times what the company is worth, it is rare that the fiduciary duty issue would force the management of a company to choose unsustainable immediate gains.

The value of a company's equity is based on the net present value of future returns. That means that while short term earnings are important, so are earnings in the moderately distant future. (depending on risk free interest rates)

If a company like Boeing were properly managed, they'd give suitable priority to engineering excellence, at least to the point of not having critical failures like these, because that's core to their ability to compete with Airbus/etc in the future.

The real issue you're concerned about is that it is very difficult to align the interests of corporate managers with the interests of the company. It is relatively easy to align senior management with short term stock prices, but it is difficult for the public to figure out that the gains they see (less engineering cost, faster turnaround time, etc) come at the expense of the longer term viability of the company, so the former gets priced into the short term stock price (and so executive compensation) and the latter does not.
Yes, initially it is easier, but it is more difficult to scale to other platforms later on. It's all dependent on how much work you want to do upfront versus in the future.

Git is basically an object storage. Most objects in Git are blobs identified by their hash code. For example, a commit points to a directory. A directory points to all files and directories it contains.

With this foundation, Git is already quite efficient in common scenarios since most commits create only a few new objects: the commit, the new versions of the files, and all directory nodes all the way to the top.

Git could store all of these in the filesystem. Often, they are stored in indexed and compressed pack files though. But the underlying principle remains the same.
It's similar to static site generators - it's easy enough to create a simple one and hundreds of people have but the real differentiator is having hundreds of high quality working templates and aint nobody got time to maintain those.

And "kin" basically means anybody or anything that contains SOME of the same DNA.
There are two factors to consider here, and those are "Will it work?" and "Will the UX be good?".

Will it work?

What we need to look for here is support for Webauthn, we can see here that all of the popular browsers support Webauthn - https://caniuse.com/?search=webauthn across desktop, iOS and Android, covering ~96% of all users.

Will the UX be good?

This is where we start to look at support for things like biometrics and generally, we'd prefer that user's passkeys are secured on their devices using biometrics rather than a PIN. In this area, the support is good across modern mobile devices (fingerprint and/or face id) and many newer desktop devices (e.g touchid). Probably the most obvious limitation here is a desktop device with no support for biometrics, however, Webauthn has a neat solution here where a user can link up this device with their smartphone using either bluetooth or by scanning a QR code - this then allows the user to login using a desktop device with a passkey secured on their mobile device.

Most of the popular password managers now also support passkeys, so that's another workaround that works well in many cases.
> > Lack of Integrated Testing / The Navy is infamous for its paperwork. It prefers standards and supplier certifications instead of actual testing (and often drags its feet on testing even when Congress mandates it).
>
> I might misunderstand the author's intent, but the US Navy does extensive testing and qualification of new ships, sometimes a year or more, just like the rest of the US military. For example, the latest aircraft carrier, the Gerald Ford, went through eight years of tests (it was a new model of carrier). For an idea of what that means,

Ford completed her first Full Ship Shock Trial ... to ensure that she is able to withstand battle conditions. 40,000 lbs. (18 tonnes) of TNT was detonated underwater, measured as a 3.9 magnitude earthquake by USGS. Additional tests were conducted in July and August, with the test detonations set off closer to the hull.

It's funny you chose Ford shock testing as an example, because the Navy wanted to shock test a later ship because _that's the way it's usually done_. The first ship in a class is always going to have teething issues. You can either a) spend the time resolving the teething issues while working around a shock test (which adds an incredible amount of time; you can for example try to change out the boilers which takes 6 months if there's a shock test scheduled 3 months for now), or b) fix the teething issues and shock test the second ship in the class

> How do you know it's related to Boeing's actions in any way?

With all of their actions in recent memory, they currently have negative benefit of the doubt; problems and issues should be assumed, and if/when they occur, public blame and shame will generally start on them until proven otherwise.

That's the consequence of throwing caution to the wind and repeatedly trashing their own reputation for a few more short-term dollars.

On some MacBook models (Intel), there was a sensor for this that you could access with the iStat menus app (among other ones) that did the same thing - it measured the power/current at "CPU Computing Highside", or in other words before the main ~12V bus that powered the CPU. Was interesting to compare the CPU package power and this figure to see the "efficiency loss" in the VRMs.

Tangentially relevant but since you mention Aussie50... brings back the memories. At the end of primary school, I used to watch Aussie50 on YouTube a lot, and discovered a number of excellent engineering channels they were associated with. He was very good at explaining how various machinery worked, and YouTube videos like these played quite a role in getting me interested in tech.

Sadly there won't be any new videos anymore, but hopefully the channel stays up/someone has a backup of it.
It is Boeing’s aircraft. Absent a sophisticated act of intentional sabotage, Boeing is at least partially responsible. The physical design, manufacturing, assembly, qualification, maintenance plans, and maintenance training are all responsibilities of the prime contractor. If a damn door falls off in flight more than one of those definitely contributed. It isn’t only Boeing. The FAA is also reasonable for verifying and requiring Boeing do all the right things and they will share blame as well as likely one or more of the several groups that will have contributed to the failure.

If you were to limit tourism to those fit enough to be allowed anywhere near a space launch, do you still think you'd reach that number?

Not to mention, space tourism being an eighth of the total tourism market is obviously insane. The total tourism market is gigantic, space tourism would do wonderfully if it it were 0.01% of it (so, 8 billion or so? Probably not enough to warrant an assembly-line approach).

I did use Qt Quick and I've been having such a great experience (as someone that used to program GUI imperatively via Qt C++ or using other framework like React/React Native) in my opinion, Qt C++ and Qt Quick is the best combo for a GUI framework. You get the performance of C++ and the simplicity, fluid animations, reactivity of QML, etc... My block editor is build in such a way that the models are in C++ and the views are in QML. This separation of logic and presentation works really well. I'll probably wrote a blog post about it.

> A stronger tool such as the Clang static analyzer should also be used.

While also teaching students that static code analyzers are very far from infallible and can waste a great deal of developer time with false positives.

It happens about once every month or two that someone posts on the sqlite forum, "I've found this serious bug..." and, after some back and forth, it's revealed that they used a static analyzer or, even worse, just pasted a single internal function from the sqlite core into ChatGPT and asked it to analyze the code for them (completely free of any calling context). Roughly 9 times out of 10, static code analyzers are flat out wrong in their analysis of that particular source tree. It's very rare that a report in sqlite which stems from a static code analyzer is actually correct.

The advice given to such posters is invariably: if you can demonstrate code which tickles the bug your tool is claiming to have found, it will be treated with priority. Until then... not so much.
I just asked myself the question for SQL's AND and OR this week. Apparently AND takes precedence but I don't know if it is consistent accross all SQL engines. In any case it seems to me that few programers will know anyway, so it is bad practice to not have parenthesis.
Modern Boeing has a consistent record for a reckless disregard for critical aspects of safety in favor of profits. So assuming that this is another case of that and calling for heads to roll at first sight is a fair reaction. That is the result of the reputation their executives have willingly built and the choices they have made.

I don't think evolution creates or produces "meaning". It is just a blind dumb mechanism which occurs when things self-replicate.

Meaning is something in the human mind, related to language. Words and other actions have "meaning". We can ask "what is the meaning of this word, or of this action?". Meaning relates to communication between individuals, not to emergent phenomena like evolution.

> Case in point is the current conflict against the Houthis, there's no use of the US Navy's very expensive radars when trying to counter-act some guys launching cheap drones from 30-40 nautical miles out (i.e. from the Yemeni shore).

There's no evidence of that. The US is not attacking the Houthi bases, period. It's not a matter of technical capabilities, it's political reasons. If the US wanted to end Houthi attacks on shipping tomorrow, then there's a couple of carrier groups in range that would stop that pretty quickly. Now, why those political limits are in place is a very good question that I would like to know the answer to as well

It should be noted that reusable rockets are fundamentally less cargo per trip than non-reusable ones, since the reusable rockets have to carry extra fuel for re-entry. The sweetspot of having enough mass to orbit so that this reduced capacity is still worth it is not at all easy to reach.

In general, if rocket building costs could really be reduced to almost nothing, reusable rockets would be useless. The only case where reusable rockets have a chance is if building rockets is still very expensive.
I hope it's not controversial to point out that agents motivated by profit will, at the limit, optimize for profit at the expense of everything else (including, in this case, safety). Airlines are less regulated today than they were back when Boeing got its start; the other quality of free and markets is that they consolidate into monopolies, at which point the market stops functioning entirely as a useful mechanism for resource allocation.
