> Didn't the SR71 fly between LA and NY at above supersonic speeds? Don't military jets fly at supersonic speeds above land?

I think not routinely in either case? Most supersonic aircraft can't actually sustain supersonic speeds for a significant period; the Concorde and Tu-144 are, as far as I know, the only aircraft ever designed with supersonic flight as the effective _default_ mode of operation. For both planes, _getting_ to supersonic was rather expensive, and required the use of afterburners, so an ideal flight profile would involve ramping up to supersonic once, and then staying that way for the rest of the flight.

The SR71 was, unusually, _capable_ of sustained long-range supersonic flight, but I can't imagine it was routinely used above land when not actually on missions; why would it be?

I think I understand. So what you're saying is that every function that can be implemented with computers must be computable. Your claim is that the brain is actually a computable function, can you tell me which one it is using your favorite version of a Turing complete instruction set? Or maybe I misunderstood and what you're saying is that the brain is not the function but what it does is compute a specific function called your mind in some unknown instruction set?

When saying “it’s profitable to lay someone off”, isn’t it implied that it’s profitable in a long-term perspective? Otherwise, it would according to the definition to be profitable to lay someone of as soon as they take their first lunch break.

Another aspect to the temporal-based techniques is that they jitter where the sample is done within the pixel, so over a few frames it accumulates more information than purely having that one sample per frame as the truth of what that pixel is. Plus if the renderer knows about the world and how its moving, and passes that to the TAA function you can track the rendered history for that element of the scene when it's moved. There's more information available to create a higher quality image for a low cost.

Render resolution has been less tightly linked to display resolution for a long time, and some games have done that on different elements in a scene for a long time (I remember seeing it in Psychonauts from 2005). Variable Rate Shading is another tool developers have to pull resources away from areas it's not going to be noticed. What I've been wondering about for a while is what's the furthest a developer could push it to smartly spend performance instead of doing it on the full frame, how much effort does it take to hint to these systems that different elements are more or less important, and then compose them together in a way that doesn't have obvious flaws.
The one comparison example is sort of poor, as the "improved" part is bright, and the "original" part is dark and rather limited. It's hard to tell much from this.

>AIs are still not able to understand negations.

AIs are able to understand negations, just ask an LLM a question. Text-to-image models are the ones that struggle the most with this, they usually do not have a very nuanced understanding of text.

How documentation affects API quality
Your definitions are very subjective. Seems you define a verb to memorize like not the same as store something in memory , even imperfectly.

I perfectly understand that the LLM developers do not want the LLM to store large chunk of text but the fact that the LLM can pull the text out exactly was proven , so even if we pretend the text was not "memorized" and we use some ridiculous verb like "it was quantum probabilistic ally vectorized" the issue is not fixed.
If your LLM can reproduce my poem then it memorized it, AI bullshiters can use other word to cope but I do not give a shit, you need a mathematical proven training algorithm or even better good data to train your LLM to not reproduce copyrighted material. Renaming concepts is bullshit.
From what I read (on that source of all truth, twitter), SR-72 was effectively canceled due to unforeseen technical challenges.

Of the 6 people I hired over the last 3 months:

3: responded to the who is hiring post

1: contacted me based on a comment I made on an unrelated thread

2: from who wants to be hired that I reached out to

In total I reached out to about 30 people from “who wants to be hired”, I heard back from 19 of them, 9 of them went on to interview (the others had already found jobs, I went back a few months looking - at least 1 of my hires had only posted 4 months ago), and I hired 2 of them.

Across all sources I interviewed 30 people (between 1-4 interviews depending on how far they got, around 70 interviews total) and hired 6.

I’m not sure if you think that proves or disproves your point, just wanted to provide the data.
It's a nice philosophy, but good luck doing this in a strict Scrum process.

I think you have very succinctly stated a reasonable "compromise", as it were, and clarified the (many) issues here ...

> Why can't Google just go build a new technology and leave the web alone?

... or develop within the medium, as is or as "it should be", this later desiderata being guided by open, agreed-upon "standards", with input by all stakeholders.-

> Why are we all marching to the drum of adtech, like there is no alternative?

In a way - and I am sure this is an "overdetermined" issue - not only because of "monetization": The web, has never developed a sufficiently workable "micropayments" solution (for example) as a compensatory mechanism for stakeholders adding value ...

... so advertising became a sort of default. Downhill from there ...
I explained above that they don't have to care, but if they're going to want to be included on major industry benchmarks like those created by Google, they should probably go to the effort of ignoring the half dozen or so notable benchmarks with canary GUIDs.

I simply doubt that most of these logs (or anyone’s, usually) are that useful.

I worked at a SaaS observability company (Datadog competitor) that was ingesting, IIRC, multiple GBps of metrics, spread across multiple regions, dozens upon dozens of cells, etc. Our log budget was 650 GB/day.

I have seen – entirely too many times – DEBUG logs running in prod endlessly, messages that are clearly INFO at best classified as ERROR, etc. Not to mention where a 3rd party library is spamming the same line continuously, and no one bothers to track down why and stop it.
I wonder how this works with things like dependency management; for example, Nx lets you build all affected projects when you change one dependency's files in a monorepo. Does this do something similar?

You can't change the reasons for which you need a new person, and you've materially benefited from the person working for low pay. But it's not guilt, it's your morality and ethics identifying a gain you made that you feel you shouldn't be comfortable with.

One suggestion, perhaps the most obvious: identify the likely pay/compensation of the person who will replace them, and then pay them the difference (or as much of it as you can) in severance over and above what you're required to offer.

Second suggestion: help find this person a new job at the kind of pay they should actually have been earning for the quality of work they were doing.

But don't feel guilt: it's more like a moral obligation. It's a good thing, not a negative emotion. It means you're thinking like a complete person in a world where it is common to pretend that isn't necessary.
When I was young, my father worked for a place where asking for a raise was a fireable offence. The founder had been a pioneer in the modern cattle-not-pets attitude toward servers, except he applied it to developers. When an employee asked for a raise, it meant on of two things:

1. The employee was a vain troublemaker who had over-value what they were worth in the market. Firing them would not only remove an inefficiency from the system (as they were likely not to work as hard if they believed that they were underpaid), but it would also helpfully remind the other developers that they were all expendable.

2. The employee was a 10x developer who was vital to the company processes and could command a much higher salary somewhere else. Even if you gave them a raise today, they could be hit by a bus tomorrow. The best course of action was to simply rip off the band aid. Fire the employee, have security immediately escort them from the building, and begin triage to ensure that the critical systems that they wrote/managed could be handled by the next resume in HR's pile.

The line I will always remember is: Developer are like eggs. They are heavily undervalued, but also will crack under too much pressure. Thankfully, like eggs, you can buy them for cheap in packs of twelve, so it doesn't matter if you break a few.

This distinction is important, but in the contexts of this engine, hypersonic is important because it roughly aligns with a performance boundary for conventional ramjets.

In a conventional ramjet, you basically have some static/static-ish structures in your inlet that uh.... "rams" into the air. This entire structure slows down the supersonic airflow to subsonic speed, and causes the pressure/temperature of the air to rise to allow for combustion.

The problem is that ramjets become less and less efficient and feasible as Mach number increases, and around Mach 6 (so technically past the hypersonic boundary), you basically can't push them any harder, and so you need a supersonic ramjet (scramjet).

In a scramjet, you only slow down the airflow to low supersonic speeds (instead of all the way to subsonic), and you feed that compressed supersonic flow into your combustion chamber.

I believe expectation for scramjets in general is that you'd only really get to Mach 10-12 or so, since above that speed rockets start providing more favorable performance.
thank you! going to fix that.
Project Ara
Upper stage engines are notoriously difficult, because the operate in a very different environment than we're used to, under annoying mass constraints, and after exposure to the rigors of a rocket launch (high vibrations and acceleration).

Also, they must ignite without any help from the ground, without any felt gravity (which really helps with pumping fuel and oxidizer).

All that makes the previous run of successful missions all the more impressive.

Before version control was popular, what did large companies do?
I was introduce to version control around 2003 (svn) and before that at small companies we would just ftp files around because we all worked on separate parts of the codebase. I didn't work at a large company (IBM, Microsoft, etc) but I'm really curious how companies with that many developers handled source control and conflicts before the likes of git and git[hub|lab] etc.
I don't have that notebook now, so I have to make up a script from my head.

I opened the webmail and logged in as usual. I read the message and I had to reply with info from another site. So I copy the info to the clipboard and go to the webmail a and I press Ctrl-[Something]. (Where [Someting] is a key that I choose carefully to avoid colissions, but I don't remember now.)

So Ctrl-[Something] triggers AHK. Something like

* Search for the buttotn that says "Reply" and press it.

* Wait a second so the new page loads.

* Search for the text "Message"

* {Tab} to advance to the text field

* Write the text: "Hello! Thanks for writing. The info you need is: "

* {Paste clipboard}

* {enter}

* Write the text: "If you need more info, please write us again."

IIRC it didn't press the "send" button automatically, because from time to time I had to customize the reply. (Also to check that the cipboard text made sense.)

I remember something about skiping a few buttons like {Tab}{Tab}{Tab}{Tab}{Tab}, but I don't remember why I needed that. Perhaps to press the "send" button???. Perhaps the text box has no label and I had to search an unrelated word and skip a few UI items???

I think I had two or three similar AHK scripts with different hot keys for different types or email. The most complex used the clipboard but other just wrote some text.

I had to reply like 20 or 30 similar email per day on an old webmail page, so this was a life saving tool. I thanked my friend extensively.

My description of the script may have errors, so if something makes no sense please ask for clarifications.
I can really only talk about the UK but I'd agree there has been a move away from better paid technical contract positions. Mostly this has been due to policy change to remove tax advantages that can come with contracting.

For large scale organisations or government organisations navigating these sort policies just isn't worth it so they simplify it and apply the same policy to everyone, which means the risk/reward isn't quite as balanced as it used to be.

Ironically, for me at least this has increased what I make as I have years of navigating the landscape, but for others it's definitely less attractive.

The more insidious side of contracting is that there has been an enormous expansion in "outsourcing" contracts that are entirely about lowering organisational costs and employer responsibilities and are exploitative without any real benefits to those employed. The majority of those contracted in these cases are almost certainly made up of outsourced ex-employees or those that would in the past have been recruited directly by organisations. In the UK and local government departments are one of the worst, having been forced to make cuts to cope with diminishing budgets.

That's what I meant with a common understanding of what the ciphertext is.

I don't think this is possible if all you have is your own recording of the ciphertext, with no proof that it was actually transferred over the wire. This is the typical situation with packet capturing at one endpoint only.
Well, that's essentially a logical tautology. Everything works according to the known laws of physics but it's certainly true that everything must also work with unknown laws of physics because of basic human ignorance.

> But practically speaking this is a unique time in history of technology because there are quick feedback loops that cause that flywheel you mentioned to be a insurmountable first mover advantage.

I'm staking my career and business on you being wrong about the insurmountable part. This is just the beginning of a long road and I'm not the only one who believes this. My partnership with Dell, Advizex and a huge soon to be announced datacenter company, isn't small beans.

Much like how I didn't know how the internet would look when I first joined in 1991. But, what I can see very clearly from my decades of experience in the tech field, is that history is repeating itself with what is happening in AI.

As I'm also prone to say... this isn't a football match where one team needs to "beat" the other. It really is enough to have multiple players in the market and nothing more than that. In fact, I'm more than happy to deploy any type of compute that my customers want me to deploy for them, including Nvidia.

Even Lamini, whom were previously AMD only, just announced [0] that they are partnering with Nvidia. Their software will run equally well on any system. Why? Because it builds a simple bridge from one platform to the next. Reminds me of the Java "write once, run anywhere" slogan. It actually worked pretty well.

I’ve been saying this for years, but I’m extremely skeptical the DARPA hypersonic programs just ceased.

The waverider program was a huge success, then suddenly funding stops and nothing is heard about it anymore. That was over 10 years ago, and now we have a commercially-developed dual cycle engine in under a year.

It’s my personal opinion that the technology was developed further internally for weapons and surveillance platforms like the SR-71 was back in the day. The technology just has too much potential.
Logic is backwards: most (not all!) high power candidates live in expensive dense cities to take advantage of easy access to other people, both for culture (e.g. art and live performances) and work (e.g. meetings, networking events, 1x1s, etc.

Put another way, there aren't enough qualified candidates outside expensive cities and therefore the salaries typically tend to go up to cover those costs of living.

In my last job, I tried using a monorepo approach, merging about 50 microservices into a single repository. After several months of growth, the size of the entire git repository reached over 100GB. We had to create monthly checkpoints (.tar.gz) to facilitate faster time traveling or quick cloning for new team members. This experience taught me that perhaps git is not the best tool for managing a monorepo.

My understanding is that there are a lot of very similar economic systems. There are pros and cons to each of these systems. I don't believe one system or government as truly figured it out.

If you define "hypersonic weapon" as merely traveling at or beyond Mach 5, then practically every medium range ballistic missile since the V-2 qualifies. There is nothing special about a missile that can hit hypersonic speeds.

The real difference is maneuvering, but most of Russia's "hypersonic weapons" cannot actually do this. Hence why Ukraine has shot down nearly every Khinzal that has been fired at Kyiv and about half of the Zircon missiles too, using technology that has existed for decades. IIRC one of the Khinzal missiles was even knocked out by a PAC-2 missile, which wasn't designed for that purpose.

Maybe AvanGuard is more competent and less overrated/overhyped than their other efforts, but there's no particularly good reason to believe that. Meanwhile the last time the US successfully tested a hypersonic weapon it was immediately greenlit for serial production, and I don't think that's because they are freaking out so much as that the US sandbags our capabilities while some of our competitors inflate theirs. You claim the Russians are ahead, but they keep putting their hypersonic engine researchers in jail. I don't buy it.
