a similar thing becomes true for motorcycle and bicycle tires in a curve, without the differential effect of two wheels on one axle: when leaned over, the contact patch of the tire deforms conically and the effect is like rolling a solo cup on the ground: it “wants” to keep turning.

Of course, pneumatic tires have cones that adjust their shape on the fly...
> 2a. Split the ball into infinite pieces 2b. Divide the infinite pieces into 5 groups

Huh? The ball is already composed of infinite points. So in 2a you recognize that the ball exists, and then in 2b you cut it into pieces. But it seems superfluous to mention 2a separately.
Restarts allow composable bridging, across components, of the interactive and batch/"server" worlds, because they can also be invoked programmatically. Of course you wouldn't want the debugger popping in your headless server app, but it could be an incredibly powerful option when you turn it on to debug a specific issue. I don't have any first hand experience in this (never doing any server side work in CL) but Paul Graham had mentioned briefly, somewhere, about ye olde Viaweb and being able to interactively debug and fix customer issues on a live system in real time. It's an appealing proposition, though I think he romanticizes it a bit.

I agree that function-level recompilation of definitions feels alarmingly undisciplined, borderline irresponsible in a production context. On the other hand, in my $work, I can recall sufficient instances where being able to compile in just a little extra targeted debug logging to a running process would've turned completely baffling production issues into something easily explained, sparing a lot of time and hard thinking trying to infer via code review the root cause of issues that no one was able to reproduce internally, and provide much greater confidence of fixes.

It's worth mentioning that on the Lisp machines, the debugger was a first class component of the user interface in a way that might feel very foreign to people accustomed to the Unix command line. It was just a way of inspecting backtraces, it was a essentially a form of interaction where the application could present a problem situation and offer the choices how to proceed.
This is cool, but definitely asks for a steep price. I can appreciate why it is as high as that, but for something that doesn't offer much practical value I personally wouldn't buy it.

I'm actually currently working on replicating the TFL departure boards[1] and creating a generic LED Matrix display that can show departures as well as other things (BTC price, Deliveroo status, and whatever else anyone can imagine. I plan to offer an API). The price point that I will need to go for worries me, but when you're putting these things together by hand there is no way they can be sold for less than £100.

> The majority of US states have similar death rates per population at around 2K deaths per 1M citizens. (with a spread of around +/- 15%)

The range is actually about 40 to 300 per 100K (or 400 to 3000 per million), but what the upthread claim seems to be about is the recent death rate, not the total death rate. No one I can find reports that per capita, but I suspect it has even more variation (California is about middle of the road for total deaths, but was an early leader with its population centers hit really hard at the beginning of the pandemic, while a number of the places in the South that weren't hit hard initially have gotten up near the top in total deaths per capita.)
It's the same thing. If the train becomes uncentered, then one wheel is the outer wheel, and will turn the axle back toward the center.

Or, looked at the other way, when the track curves, then the axle becomes uncentered.

Seriously. I hate to be a dick, but I don't get how it's often possible to believe something that stupid (despite the fact that many, many people do, especially on HN). This model of corporations' decision as incapable of being influenced by anything but maximizing profit in a vacuum is trivially belied by examples like this[1].

(To head off the inevitable-but-nonsensical response that averting an employee revolt helps the bottom line...that's trivially true, but turns the statement into a tautological one, defining a "corporation" as some formless void that somehow doesn't include anyone making the decisions).

In principle it could but AFAIK Starlink is restricting installations to fixed land-based applications for now because they want a predictable number of customers in each satellite footprint. I expect they will extend it to marine applications in the future. Cruise ships in the near future (assuming cruise ships ever come back after COVID) will all have some kind of high-bandwidth LEO satellite internet connectivity.
IMHO, to realize that I am not working as diligently or effectively as I ought to be and being ok with it, is the best thing ever happened to me. I'm not a machine, my goal is not to become better or more productive. As one once said: "self-improvement is just masturbation". I look for the higher goal: long-term satisfaction.

And to be honest, I imagine Fowler could already retire and have zero financial problems for the rest of his life; that helps a lot regarding giving a damn about productivity.

> I sincerely hate you libertariantsy types

Huh. I didn't realize it was a libertarian view that one should be responsible for outcomes that are obviously the result of decisions they made (and still make).

> I can happily live without commute, you can go to office for all I care.

Right. A choice that each of us can individually make. I've made mine and you make yours. I am simply stating that one should take personal responsibility.

In general, your employer shouldn't/doesn't care how long you have to commute to work. Why? Because you are replaceable with someone who doesn't have this problem or won't whine about it.

Stop externalizing blame. Your quality of life will increase greatly once you stop expecting other people to solve problems you create and just solve them yourself.

> dude be a bit empathetic.

Empathy for what, exactly? OP can get a job closer to their home OR move closer to their job OR find a remote only job. It isn't their employer's responsibility to endlessly subsidize and cater to the choices of their employees.

Regarding your other assumptions: I am outside of the age group you mention and have children + distant family.

Can you read the definition? “Local Universe - Studies of the nearby universe encompass a region of approximately 1 billion light years in radius, over which the effects of cosmic evolution are small.”
A lot of people feel the need to overcommit in the chase to try to become an all time great at a thing. While overcomitting they miss out on many other things in life and have poor relationships along the way. Often not realizing the lack in quality of the relationships until they regret it.

But it's still a somewhat larger device dedicated to a single function.

For me, I'm not sure I'd want inReach-type capability in my phone if it was another monthly subscription fee. I'd prefer a separate extremely rugged device given that, when I might really need it, there's a decent chance I'm in really crappy weather, have gloves on, my face covered, etc. Who wants to be fiddling with their phone under those conditions?

In regular natural language, cutting the ball into 5 pieces implies cutting 5 contiguous pieces.

> We realized soon that it's hard to monetize such [self-hosted product]

Spot on. We iterated on a similar product in this space: "privacy preserving", "self-hosted", "open source" etc. But focused on local AI indexing & search of personal videos and photos [0], rather than backups.

We ultimately shelved VideoNinja because we weren't able to find a sustainable business angle:

* Non-technical people simply don't care (happy locked into Apple / Google).

* Technical people understood the proposition, but are super stingy. Case in point, see the responses in this very thread: "$10 per year max; I can buy a HDD for less!". That's one (cheap) restaurant meal per year.

So I fully understand your decision to go "cloud". Although that immediately takes your product off the table for me personally. I want nothing of mine (of value) in the cloud.

I feel there must be a way to square that circle, the market exists.

It's sort of hilarious to see a physics site mention the Banach-Tarski paradox. It is, after all, the most obvious hole poked in the most basic working assumption used by physicists: that space and time are measured with real numbers.

I've seen physicists go to pretty absurd extremes to avoid thinking about the problems this creates. Fixing it properly is not easy: simply dropping the axiom of choice leaves you unable to do useful physics. Getting back to a useful state, making all sets Lebesgue, can only be done with large cardinals:

https://www.jstor.org/stable/1970696

Large cardinals are pretty exotic even by the standards of mathematicians. In many departments they are in fact the domain of logicians. In fact, the existence of certain classes of Woodin cardinals is equivalent to the Axiom of Determinacy (AD), which is the "mathematically respectable" way of investigating logics with infinitary conjunction/disjunction. In fact, AD is precisely the Law of Excluded Middle (A or not-A) for logics with infinitely-long conjunctions.

Quite odd that something so ethereal would be connected to a tangible act like cutting an apple in half.
Agree. I would go further and say: good companies hire SREs to be the ones on-call (just like good companies hire QA engineers for testing, and designers for UI/UX topics).
Your posts have no value. You've said nothing of substance, made no valid criticism. If you just want to vent go talk to a therapist, don't waste precious bytes.
I have spent quite a lot of time thinking about coordination in general. Indeed, knowledge is a vital part of it. The problem that I see is that knowledge is too vague and lossy and changing and incomplete [as I mentioned in this comment https://news.ycombinator.com/item?id=26203718].

An hypothetical solution would be a system that talked a language similar to plain english, but that was determinist. You let people write their problems and views to the system, and the system determines which are the widest consensus available within a given scope and what are the highest priority problems (perceived by people). This has a lot of problems, but it's a good way to think about the topic. Even with such a system, would you really be solving the problems you want to solve?

If it does, then this is basically symbolic AI. You can try to relax requirements... but you kinda need an "automatic coordinator". If you go with a manual coordinator instead, then I doubt you will be able to scale anything that's not extremely rigid and hierarchical, at which point you are re-introducing many of the same problems you were trying to fight in the first place.
I had a discussion with a friend in college about this. We were both doing dual bachelors in Music and Physics, graduation was approaching, and it was coming time for each of us to choose whether we'd pursue research, art, or other.

He was perhaps smarter than me and worked harder. I asked him what it was that motivated him, and he said that it was a sense of guilt that had been instilled in him by his parents. I told him that guilt is a destructive motivator, at least in the long run. He replied that it actually worked well for him and he was glad to have it.

I also am sometimes motivated by guilt. Does it bother me because I'm more aware of it, or am I right in thinking that there are better motivations within reach?

The problem here is due to a lack of basic security practices. There is nothing related to old code, it is brand new code and infrastructure that was deployed without audit.
Motorcycles turn at speed by a similar principle, though the cones arrangement is a bit flipped around.

I usually demonstrate it with two solo cups put mouth-to-mouth, to make a pair of facing cones that represents the motorcycle tire. The starting condition is that you're above parking lot speeds, and the bike is stable and is dynamically inclined to stay perfectly upright. To go left, you turn the bars right to upset the stable bike onto the left cone, and it goes left. To go right you turn the bars left and it upsets the bike onto the right cone, and goes right.
I think micro-business as a term exists (and depending on the exact definition is typically 0-4 full-time employees, including the owner).

Google gives 1 million characters per month free which I don't often go over, but this will be really useful for when I do

I don't want to be unappreciative, it's amazing that this is possible much less free, but when you spend hours listening to it every day, the cracking and warbling do get old. I think there are better models I've heard snippets of but the truly amazing thing about google's is how robust it is to very weird words

(When I tried all the public cloud offering's, IBM's was the marginally nicest AFAICT but it was the most expensive with least free quota)
Younger people can help evolve topics by providing a set of fresh eyes. It's also important to pass knowledge on, otherwise it just ends up dying with you.

For example: Virtual reality headsets were fairly stagnant until a young guy in his early 20s tried something new.

Old people often become stuck in their ways and it requires someone new to show up and ask how the sausage is made.
Train cars have plenty of circulation it's not the heat locker youre describing.

Also it's 100% guaranteed that wearing masks is safer than not wearing them, and it's minimal effort. So just use common sense and wear the mask, it's working great for managing covid in Asia.

Your logic is basically this: "I heard of a study that suggest masks are less effective in an environment." --> "lets not wear masks and maximize our chances of spreading covid. Because there's a study that suggests masks are less effective in certain environments"
You have learned a good skill, which is knowing how and when to stop. That is something I have a very, very hard time with.
I was taught that dropping the axiom of choice was enough to make Banach-Tarski go away. That seems considerably short of "there is no such thing as an infinite number".

But the Twitter link at the top of this thread seems to have a rather more interesting way of doing so.

I think this is more of an industry problem than a Microsoft problem. This was a feature added onto an existing service. The old waterfall method of security approvals might have caught this, but for most orgs that has gone the way of the dodo (and probably for the better).

Cosmos DB probably went through security review during the design phase and then again regularly as the code was written and improved. The Jupyter notebook functionality was also likely reviewed by security teams during the design, testing, and implementation phases. But once you're through those approvals most security review is going to be done via automated tooling with only occasional re-reviews and penetration testing at scheduled intervals. Automated testing is great at detecting vulnerabilities that have been discovered in the past, but really not good at detecting new classes of vulnerabilities, hard-to-detect authorization vulnerabilities, or how code integrates with other services.

Once the initial approval and code reviews had been done developers would still be committing code to the service and each line of code is probably not receiving a manual code review. Vulnerabilities like this are hard to detect even with a manual review as the testing team may not have great knowledge of all interconnected services, especially if it's an outside vendor.
This is why I'll never try to build a silent system. Coil whine + fans communicate quite alot, but also fade into the background. Something about the noise from the fan just modulating slightly makes it less intrusive for me than a sound coming out of silence.
The 1_000_000 thing exists in perl as well (I think also via theft from Ada) and frankly I can't understand why everybody hasn't stolen it.
This is a brilliant mission. Postgres is commoditising the database in an amazing way.
Everyone I know who has chose a career based on passion has grown to view it as work eventually, they still enjoy parts of it but monetizing something you love and doing it 40+ hours a week turns it into work. I have friends who loved animation/art but actually working for a gaming company ended up being miserable. And 1000x would mean I could work for 1 month and make ~85 years of income so… I would be fine with that lol.
GitHub does not support IPv6
Personally I would want freedom to just put whatever URL I want, as my search engine. Every popular desktop browser has this feature and I don't see why it could not exist on the iPhone. I bet Apple would claim that it's "taking away options to help people".
Years ago I was writing a utility called Cookie Toss, that would go through a user's cookies and save all the tracking cookies to a database while replacing them with a random assortment of other peoples' tracking cookies.

I had a limited working demo for Firefox, but then was unceremoniously warned that I would end up sued by every ad company targeted, and the costs to me would become insurmountable.

So it was a great idea while it lasted. Maybe some random anonymous person will take the idea and fly with it. They're welcome to the clever name, too.
You are right that transparent high-bandwidth satellite fall back is not in the cards at the moment. I will challenge you that high bandwidth is a hard requirement in this case. If Apple can integrate emergency short text + location capability at a low marginal cost, it will make iPhone platform more attractive to people who aspire spending time outside of cell coverage.

First, let's examine some limitations we are dealing with:

1. On the receiving side the trade is power projected on the receiving terminal vs bandwidth. At lower bandwidth we can have quite reasonable power requirements, think GPS antennas. High bandwidth applications are all limited by FCC power per cm2 projection limits. Without those limits LEO satellites could focus transmit onto a much smaller area and enable high-bandwidth receivers that are basically cell-phone sized. Given that GPS is a thing, we can definitely have low-bandwidth phone integrated satellite antenna.

2. On the transmit side primary trade is again transmit power vs bandwidth. Iridium phones are a thing https://www.iridium.com/products/iridium-extreme/, so low bandwith transmit is feasible.

Overall, I think it is quite unlikely that Apple is adding a dedicated on-handset satellite coms. It is possible, maybe even likely, they will be enhancing existing satellite communication capability or adding external devices. Even if they are enhancing satellite coms the provider is definitely not Starlink because phased array power requirements are staggering for mobile applications. So, assuming there is some truth to this leak, it is maybe 1, probably not 3, and almost definitely not 2:

1. Upgrading the existing GPS capability with new antenna / silicon. Most likely to support other positioning constellations https://www.quora.com/What-are-the-competitors-to-GPS, but in era of SDRs maybe sat signals in general.

2. The claim specifically talks about phone/text calls, to make that happen they will either need to integrate with Iridium or back a new not yet deployed service. On Iridium front there are a couple of problems, but they don't seem insurmountable: Iridium modems are expensive and iPhone power/thermal requirements will mean developing logic that is significantly better than anything on the market. Of course Iridium IP licensing or company acquisition would be big news breaking quite a bit before we see any devices, so this is almost certainly not happening.

3. First party integration of external satellite antenna into iPhone ecosystem. Introducing Apple emergency beacon. Deploy this beacon anywhere in the world and get emergency communications for affordable* price. Basically a modern, Apple sleek, version of https://www.iridium.com/blog/2012/05/23/iridium-connected-de... .
