It wasn’t the opposite .

By 2015 they were trying to hide how much of the group growth and profits were largely contributed by just AWS , i.e. they were hiding the e-commerce margins .

Without AWS and subscriptions, Amazon is quite an unprofitable company.

Both overall growth and margin driven by AWS(and prime) while E-commerce revenue remains outsized because they count GMV as revenue which is iffy even when they own the merchandise, but being largely a marketplace these days GMV is very misleading metric.

It would be like Stripe decided to count their revenue as $1.4T the amount they processed this year as revenue rather than $10-20B they actually got after paying the banks, merchants , VISA etc . This 20B is not profit either just the pie from which salaries cloud costs etc have to be paid to get to actual profit.

Most of the reports on the downdetector heatmap are coming from the NYC area, that's probably more likely to be a network issue (or even, if you can imagine it, DNS) than a real AWS failure since it's well into business hours on the West Coast.

Would appreciate anyone's thoughts. I know I didn't provide a lot of details but that was purposeful. I'm looking for feedback from fellow engineers who are interested in building a convergent system. The reason its called a "redprint" (as opposed to a "blueprint") is because in my mind this is an evolving layer of AI we're just beginning to grasp. The architecture itself is meant to shift as the agents self-improve. For decades the field of AI research has been split across many domains and experts. However I believe Redprint is a step towards fusing many of these ideas into a practical framework for Cognition itself.

Please chime in if you feel any interest in the subject. I'm not asking for money or hype or anything like that. Ideally someone who's ready to challenge what I have set forth and perhaps participate in the building.

> industry-standard quality control ... proven approach

proven for the private market(s) != proven (or even acceptable) for governments

do the risk analysis. what happens when an industry-standard quality control measure fails in whatever way for a private company? some hit to their reputation, stock price, market share, maybe they even fail. these are perfectly acceptable outcomes for a private organization. they are not acceptable outcomes for governments. governments demand (much) higher standards and more stringent processes. slowness is a feature, not a bug.

What justifies the V4 Plus being worth $350? They're using the CM4 so they’ve made a PCB, but what hardware are they adding over the peripherals available on a Pi 4/5? All I can tell is an additional Ethernet port, a SIM card tray, and an “ATX controller”.

What does the board look like, why can’t I DIY that version, etc. Are they just trying to make it up with the software (that I also can’t tell what it looks like).

I both read a fair amount (and long books, 800-1,000 page classic Russian novels, that kind of thing) and use LLMs.

I quite like using LLMs to learn new things. But I agree: I can't stand reading blog posts written by LLMs. Perhaps it is about expectations. A blog post I am expecting to gain a view into an individual's thinking; for an AI, I am looking into an abyss of whirring matrix-shaped gears.

There's nothing wrong with the abyss of matrices, but if I'm at a party and start talking with someone, and get the whirring sound of gears instead of the expected human banter, I'm a little disturbed. And it feels the same for blog content: these are personal communications; machines have their place and their use, but if I get a machine when I'm expecting something personal, it counters expectations.

The paid for feature seems to show the number of dislikes that have the extension installed, however what is shown is the estimated number of dislikes based on the actual number of likes youtube shows, so if the extension users have a like/dislike ratio of 50%, and there youtube shows 1000 likes, the extension estimates that there are also a 1000 users that disliked the video, even though there may only be 1 like and 1 dislike from the extension users, which would be very obvious that the estimate is very off.

Also, never set jobs to run at midnight (00:00) as nobody will be able to tell what day it is. Set it to 00:01 or something.

And tbh, don't run jobs on the hour anyway. Everything kicks off then. Set stuff to run at 01:45 or 02:15 or something instead.

(None of these suggestions are time change related)

Having tried many times to use local time instead of UTC to make life simpler for myself, I really don't think it's ever a good idea.

Better to localize times for users on the client-side based on their local settings, IMHO

For quotas and usage limit resets it can be a little harder, but if it's a cron job anyway, my initial approach would be to just schedule it for a time that is close to midnight for the area your customers are in.

As someone who briefly wrote a bunch of AI generated blog posts, I kind of agree... The voicing is terrible, and the only thing it it does particularly well is replace the existing slop.

I'm starting to pivot and realize that quality is actually way more important than I thought, especially in a world where it is very easy to create things of low quality using AI.

Another place I've noticed it is in hiring. There are so many low quality applications its insane. One application with a full GitHub and profile and cover letter and or video which actually demonstrates that you understand where you are applying is worth more than 100 low quality ones.

It's gone from a charming gimmick to quickly becoming an ick.

Definitely! For self-hosted as a product I think Ubiquiti's Unifi Protect is easiest. (but there's free software options like Frigate)

You just need a console (NVR) and the a camera. Here's what I use:

- https://store.ui.com/us/en/category/cloud-gateways-compact/c...

- and a wireless camera: https://store.ui.com/us/en/products/uvc-g6-ins

and the camera has a standard 1/4" female thread mount, so also a stand to hold the camera. And in the UniFi protect setting enable "Hallway Mode" to rotate it 90 degrees to get the length of baby.

Why we care about Busy Beaver numbers, from “Who Can Name the Bigger Number?” by Scott Aaronson:

Now, suppose we knew the Nth Busy Beaver number, which we’ll call BB(N). Then we could decide whether any Turing machine with N rules halts on a blank tape. We’d just have to run the machine: if it halts, fine; but if it doesn’t halt within BB(N) steps, then we know it never will halt, since BB(N) is the maximum number of steps it could make before halting. Similarly, if you knew that all mortals died before age 200, then if Sally lived to be 200, you could conclude that Sally was immortal. So no Turing machine can list the Busy Beaver numbers—for if it could, it could solve the Halting Problem, which we already know is impossible.

But here’s a curious fact. Suppose we could name a number greater than the Nth Busy Beaver number BB(N). Call this number D for dam, since like a beaver dam, it’s a roof for the Busy Beaver below. With D in hand, computing BB(N) itself becomes easy: we just need to simulate all the Turing machines with N rules. The ones that haven’t halted within D steps—the ones that bash through the dam’s roof—never will halt. So we can list exactly which machines halt, and among these, the maximum number of steps that any machine takes before it halts is BB(N).

Conclusion? The sequence of Busy Beaver numbers, BB(1), BB(2), and so on, grows faster than any computable sequence. Faster than exponentials, stacked exponentials, the Ackermann sequence, you name it. Because if a Turing machine could compute a sequence that grows faster than Busy Beaver, then it could use that sequence to obtain the D‘s—the beaver dams. And with those D’s, it could list the Busy Beaver numbers, which (sound familiar?) we already know is impossible. The Busy Beaver sequence is non-computable, solely because it grows stupendously fast—too fast for any computer to keep up with it, even in principle.

I'm not sure if this has been mentioned here yet, and I don't want to be pedantic, but for centuries famous artists, musicians, writers, etc. have used assistants to do their work for them. The list includes (but in no way is this complete): DaVinci, Michelangelo, Rembrandt, Rubens, Raphael, Warhol, Koons, O'Keefe, Hepworth, Hockney, Stephen King, Clancy, Dumas, Patterson, Elvis, Elton John, etc. etc. Further, most scientific, engineering and artistic innovations are made "on the shoulders of giants." As the saying goes: there is nothing new under the sun. Nothing. I suggest that the use of an LLM for writing is just another tool of human creativity to be used freely and often to produce even more interesting and valuable content.
by ribosometronome | 2025-10-27 17:41:14+00:00
I think the almond talking point takes hold because, like a lot of complaining about LLM usage, large parts of the blame gets directed elsewhere rather than the choices that we're all way more likely to be making and could influence. Like, it's 2025. Even the people most likely to be drinking almond milk have largely moved to oat, whose water usage is great.

> why we define the Action as this object and why we should expect it to be minimised for the physical trajectory in the first place.

The most coherent explanation I've heard was from Feynnman [0]. As far as I understand it (and I may well not have understood it at all well), at the quantum level, all paths are taken by a particle but the contributions of the paths away from the stationary point tend to cancel each other. So, at a macroscopic level, the net effect appears to be be that the particle is following the path of least action.

> a proof of the equivalence to Newtonian mechanics

The Lagrangian method isn't really equivalent to Newton's method. Again, Feynman talks about this in [0]. It's that for a certain class of action, the Euler-Lagrange equations are equivalent to Newton's laws.

It's perfectly plausible to come up with actions that recover systems that represent Einsteinian relativity or quantum mechanics. This is the main reason (as I understand it) why it's considered a more powerful formalism.

over 50% less the price, I see the JetKVM at $90 USD, but PiKVMs range from $230+.

I found PiKVM useful as I already had the hardware laying around, so setting one up didn't cost me anything, and its a pretty good experience. If I were to buy new though, not sure I'd find it worth the cost for my use case.

Exactly. If it's substantially the writer's own thoughts and/or words, who cares if they collaborated with an LLM, or autocomplete, or a spelling/grammar-checker, or a friend, or a coworker, or someone from Fiverr? This is just looking for arbitrary reasons to be upset.

If it's not substantially their own writing or ideas, then sure, they shouldn't pass it off as such and claim individual authorship. That's a different issue entirely. However, if someone just wanted to share, "I'm 50 prompts deep exploring this niche topic with GPT-5 and learned something interesting; quoted below is a response with sources that I've fact-checked against" or "I posted on /r/AskHistorians and received this fascinating response from /u/jerryseinfeld", I could respect that.

In any case, if someone is posting low-quality content, blame the author, not the tools they happened to use. OOP may as well say they only want to read blog posts written with vim and emacs users should stay off the internet.

I just don't see the point in gatekeeping. If someone has something valuable to share, they should feel free to use whatever resources they have available to maximize the value provided. If using AI makes the difference between a rambling draft riddled with grammatical and factual errors, and a more readable and information-dense post at half the length with fewer inaccuracies, use AI.

What's really sad here is that it is all form over function. The original got the point across, didn't waste words and managed to be mostly coherent. The result, after spending a lot of time on coaxing the AI through the various rewrites (11!) was utter garbage. You'd hope that we somehow reach a stage where people realize that what you think is what matters and not how pretty the packaging is. But with middle management usually clueless we've conditioned people to having an audience that doesn't care either, they go by word count rather than by signal:noise ratio, clarity and correctness.

This whole AI thing is rapidly becoming very tiresome. But the trend seems to be to push it everywhere, regardless of merit.

I try to avoid crons at the top of the hour, partly because of this... but also because (in shared / serverless infrastructure) I assume a lot more people are setting their crons for 'on the hour' so there's more resource contention... I also aim for 'after 4am' where I can as well, or 'before midnight', to avoid this whole range.

If I want a report of what happened at a specific time I need that report at local time

I get a daily status report of various things from our 24 hour operational management team which runs at 8am UK time every day. That means last week it ran at 0700UTC and this week at 0800UTC

This is built around operational events, shift changes, etc.

I've got another system which is in operation in Sydney from 0630 to 1630 local time, this means that maintence windows which overlap with UK shift patterns depend on the week but mean the system is operating 2130-0730 UK time at some times, 2030-0630 UK at others, and 1930-0530 at others.

UTC is not "the answer". Sometimes you want things running at a UTC time, sometimes you want them running at local time.

I have a regular meeting at 10am London time on Tuesday and Thursday. That can't be stored in UTC as it varies depending on the time of the year. It has to have the timezone stored and actioned.

The fact that essentially every major ISA except x86 has support for big-endian including the two latest big-name entries (ARMv8 and RISC-V) contradicts this assertion.

Most importantly, big-endian numbers have overwhelmingly won the human factor. If I write 4567, you don't interpret it as 7 thousand 6 hundred and fifty-four. Even an "inverted big-endian" (writing the entire sequence backward rather than partially forward and partially backward like little endian) makes more sense and would be much more at home with right-to-left readers more than little endian too.

They already get paid to do that - the 30% is completely unrelated to that.

That's also optional. Apple chooses to develop iOS because it becomes a new pathway for siphoning money from consumers and developers, and allows them to create their walled garden.

They could just stop at any point and use android or even off-the-shelf Linux with an OS mobile environment.

I've been really happy with my JetKVM. The tariff situation is unfortunate, my recollection is that it was something like $50 during the kickstarter (could be wrong, didn't check). Looking around a bit, I'm not sure I see anything remotely as hackable at a competitive price, so maybe $90 is still a great deal.

It would be awesome if they made a PoE version.
Understanding MCP Servers
by ematth | 2025-10-27 17:44:10+00:00
Hi everyone,

I've been keeping up with the state-of-the-art in AI development for a while, and MCP Servers have recently become popular. Even though I've walked through several tutorials and explanations, I'm still a little lost on what makes MCP a breakthrough in the AI space. Is it that they act as easy-plug-in tools for models for problems that they can't solve easily or would just make a guess on? This is my best understanding, so I'd love to hear from all of you on what makes MCP important. Thanks :)

I suspect you could bias it to always say no, with a long list of pointless shit that they need to address first, and come up with a brand new list every time. maybe even prompt "suggest ten things to remove to make it simpler".

ultimately I'm happy to fight fire with fire. there was a time I used to debate homophobes on social media - I ended up writing a very comprehensive list of rebuttals so I could just copy and paste in response to their cookie cutter gotchas.

I've told this story before, but it's super relevant here. When I set up all the servers for reddit, I set them all to Arizona time. Arizona does not have DST, and is only one hour off of California (where we all were) for five months, and the same as here the rest of the year.

I didn't use UTC because subtracting eight when reading raw logs is a lot harder than subtracting one.

They use UTC now, which makes sense since they have a global workforce and log reading interfaces that can automatically change timezones on display.

What bugs me most is the rent seeking on some of the tlds... dynamic pricing which is higher for simple English words. And what happens if your domain gets popular, are they going to just jack up your rent from $25/yr to $500/yr or more?

I have a few domains that I've been sitting on with every intention of getting to, but tbh, I'm about ready to just drop half of them (of around 35 or so), just because the annual costs just to keep it are getting to be too much.

Definitely some heinous-sounding stuff.

The third result was "FREE $FOO PORN" where $FOO was something that nearly the entire human race recognizes as deeply Not Okay and is illegal everywhere.

I wonder what % of the heinous-sounding sites are actually providing the things they say they are.

I'm sure that some (most?) of them actually offer heinous stuff. But surely some of them are honeypots run by law enforcement and some are just straight up scams. However, I have no sense of whether that percentage is 1% or 99%.

From a constitutional perspective, I find a different question much more interesting:

What method does the Constitution provide to handle a situation when a sitting President, with the support of the DOJ and FBI, refuses to leave after his term has expired?

Or a sitting President who is impeached by the House and Convicted by the Senate, but who, with the full backing of the DOJ and FBI, refuses to step aside?

The subreddit also had a policy of not unlocking the megathread until the leaderboard was filled up. So any hints there will also be too late for the making the global leaderboard.

And the old About noted what you just said about there being nothing preventing someone from using AI:

> If you want to use AI to help you solve puzzles, I can't really stop you, but I feel like it's harder to get better at programming if you ask an AI to do the programming for you.

> Bevy is just a very good, modern graphics tech demo, not something suitable for developing actual games.

I would agree with you that bevy is not fit for making a commercial game. but not because its not capable. Its just NEW. we are only now starting to see commercial games come out with godot and thats 11 years old. bevy came out what, late 2021? give it some time. It still needs more workflow tools, a level editor stable documentation and a bunch of other things.

It will get there. it just takes time.

They also added more to the 365 Family Manager family premium plan though -- they ended Copilot Pro as that was an add-on that made no sense when people already had to juggle the other two copilots that are finally "settling in".

Good move there, at least.

You are correct about the US in relation to trademarks. The situation there is rather complex, with it being possible for people to just add TM to their texts and ask other people to do the same and it is considered legally binding. They can take the extra step of registering and then they add (R) to their texts and that gets them an even stronger legal case.

Because of the case law nature of the US legal system and the informality of TM, if other people start using the term in other ways (for example using "xerox" as a verb meaning "copy") and you don't show an effort to curb that then you can lose your trademark.

In other countries things are different. Brazil, for example, uses a Latin legal system which is more formal. So the only thing that matters is whether you have registered the trademark with INPI (National Institute for Intellectual Property) or not. Which is why Gradiente owned the iPhone trademark in Brazil even though they were not using it anymore (it was from a product from around 2000) and if you asked anybody on the streets in Brazil they would associate the name with Apple.

That is a common refrain by people who have no domain expertise in anything outside of tech.

Spend a few years in an insurance company, a manufacturing plant, or a hospital, and then the assertion that the frontier labs will figure it out appears patently absurd. (After all, it takes humans years to understand just a part of these institutions, and they have good-functioning memory.)

This belief that tier 5 is useless is itself a tell of a vulnerability: the LLMs are advancing fastest in domain-expertise-free generalized technical knowledge; if you have no domain expertise outside of tech, you are most vulnerable to their march of capability, and it is those with domain expertise who will rely increasingly less on those who have nothing to offer but generalized technical knowledge.

I've been using it since I got it. It's been working great with one small issue that I haven't been able to solve. For some reason when I use plasma on Arch linux (but not ubuntu), the display outputs garbage. I'm guessing it's not detecting the EDID correctly and setting a weird resolution or refresh rate. It's not a major issue since other desktop work well so I haven't spent much time looking into it.

How well does change tracking work in Excel... how hard would it be to review LLM changes?

AFAIK there is no 'git for Excel to diff and undo', especially not built-in (aka 'for free' both cost-wise and add-ons/macros not allowed security-wise).

My limited experience has been that it is difficult to keep LLMs from changing random things besides what they're asked to change, which could cause big problems if unattackable in Excel.
