That's true, but it leaves out the other half of the equation: you'll still likely spend less of your valuable time on your making your Ubuntu installation work, than on anything else (speaking as someone with commercial dev experience on MacOS, Windows, Linux, and FreeBSD).

I spent hours trying to stabilise my wife's XPS13 after a recent Windows Update sent it into paroxysms of BSODs. Reset, reimaged, the whole nine yards: nothing. Ended up installing Ubuntu on it and it's been rock-solid stable since.
>The problem is that in aggregate you end up with an internet with a single point of failure.

And the other problem, which I'm pointing at, is that without using something like Cloudflare, you end giving yourself more points of failure (more pressure, DDoS, lack of easy load balancing, most costs and devops to implement those yourself, etc).

And each site doesn't care if 10000 others go down together -- if anything that's good, if their competitors go down for a while. They care for their own status...

>And even if as it is now isn't a big problem, who's to say that one day it is a huge problem?

I'd say periodic mass failures should inform our usage and dependance patterns of the internet so that we're not 100% dependent on it 24/7, in which case sites going down together never becomes "a huge problem".

In other words, one way to never have it be a huge problem is to make the internet perfectly decentralized (which is impossible anyway -- first because sites people care about is a power law distribution, e.g. Google, MS, Amazon, stores, app stores, etc, so if Google goes down there's a disruption to billions of people, even if millions of lesser sites are up that much fewer care about, -- and second because critical instrastructure is shared, e.g. undersea cables etc.

The other way to never have it be a huge problem is to learn and adapt to situations when sites might be done, and build resilient alternative ways of operation (analogue, if need be).
The way I like to explain this is to start from an intensional definition of money as "something that has no value by itself but can be potentially exchanged for something of that value". And total amount of money in economy is the total amount of these things at a given point in time.

So when somebody creates an IOU trusted enough so it could be resold, they have effectively created "money" according to the above definition, because now that IOU can be traded _independently_ of the thing it was originally exchanged for.

I think what confuses lot of people about this is that creation of money is a 3-sided transaction, and we are conditioned to think of a market economy as a sequences of 2-sided transactions.

Also, what I find very funny, some libertarians want to impose government to only create money backed by a commodity, like a gold standard. Yet their fundamental axiom is to allow any two parties to enter (almost) any contract, in particular, allow them to create and resell IOUs. However, if the government has to enforce any contract that two parties can come up with, this is already giving too much freedom for the money to be created regardless of the actual commodities in existence, and regardless what the government does.
Where I live a pint is 0.5L and a metric cup is 0.25L.
Take this with 2 cents since I'm not versed explicitly in Zen architecture, but it's likely only the SP. Usage patterns are fairly easy to deduce at compile time and are optimized, i.e. loop tiling, thus I think it's fair to assume the optimizations are leveraged against this. For example, if you can predict the loop pattern you can repurpose the SP.
Non-physicist here, so excuse the layman rambling, but to me this was always something I just assumed when asking myself how fast is time? I just figured it was a constant because it is, it doesn't slow down or speed up - well, except for when you're doing really tedious work of course!). So, I just always assumed that if it's a constant, then it must be equal to the fastest or slowest constants we know.

That always leads me to this (probably) crazy rabbit hole I can never quite articulate or resolve that no doubt countless others have wondered about - what if it's not moving at all? What if time is 'solid'?

I guess the best way to explain what I mean here is like a flip book. On each page there is a drawing, if you look at one page you just see a static drawing. If you look at the book, it's just a static book. But if you flip through the pages, it animates and appears to be moving.

What if our experience of time is just like this 'flip book' experience, where in actuality, our experience of time is that we are moving through it, but time is not moving at all?

I'd love to know if there have been any other studies or discussions about this? Because if time is a constant, it could also be 0, no?
That’s not true. You can have decimals for any base.

10/5 in Base 12 is 2.49724972497...

Or binary (Base 2)

1011/101 = 10.0011001100...

Duodecimal metric system would have the same features that you’re talking about (which have nothing to do with the base).
With sims, and particularly when you're new to sims, I recommend turning on assists and just going for it. IRL we have rigorous flight training because planes are expensive and there's no reset button, but in sims there's nothing wrong with just taking something up and crashing a few dozen times while you figure things out.

Many of us who are playing today also got our start with very simple and forgiving sims. When I got into them, there was no mixture, no prop pitch, no spins, no torque, and no p-factor (which was good, because I didn't bother binding rudder controls). It's a lot easier if you enable that stuff a few at a time, once you get the hang of the basics.
Yeah, I'm using Java, so in practice this means I extended my JDBC DataSource. On every call to getConnection() it sets the schema.
You sue whoever looks to be to blame. So perhaps the victim’s family sues the car owner. The car owner then sues the car manufacturer if they feel it was to blame. If the company feels an individual engineer was to blame they might sue the engineer. Basically just let the courts figure out the balance between societal harm and responsibility.
Vermaden and FreeBSD and HP Elitebook = Nice
It should be stated somewhere here that relativity operates in Minkowski space and not Euclidian 4D space.

What this means is that the length of a relativistic four-vector [ct, x, y, z] is sqrt((ct)^2 - (x^2 + y^2 + z^2)).

It is not the same as the Euclidian magnitude, i.e. NOT sqrt((ct)^2 + x^2 + y^2 + z^2)

The article does mention this, although with slightly confusing wording, but it should be emphasized that Lorentz invariant quantities need to be computed with the Minkowski metric.
FWIW the amount of time I've spent fiddling with my OS in the last year approaches zero, and I don't remember it being this unintrusive when I was using Windows or macOS at work.

Nothing just works quite like something that simply hasn't changed.

In the amount of time I used to spend in a month making sure macOS wasn't on the brink; a couple weeks ago I investigated and implemented a feature in a system component, one that is not present on any commercially available desktop operating system.

Now my input method client displays language-appropriate glyph variants based on the input method's locale, and you just managed to get the App Store to shut up, or fix some of your homebrew after a system upgrade.
Sorry, but I fail to see the brocken system here.. Isn't the calculation true?
CRAMs are both several tons in weight, require a lot of power and special mounting, and are found mounted on a warship or in a military base; you're not really going to worry about some random insurgent carrying it off. Besides, they eat 20x102mm ammunition, which isn't exactly common stuff.

That is a far cry from the consequences of leaving a M240 around, which is both man portable and consumes the incredibly common 7.62x51mm NATO cartridge.
I wonder why this can even happen. Tesla cars have some kind of radar for front distance, no?
It's a good sound bite but I don't think it really reflects the reality of parenting. I know reality is that helicopter parents have taken over but I'm a light-touch parent. To me parents helicopter because they're bad at politics. When my daughter had trouble with boys or tried drugs I knew immediately because I've never given her something I couldn't compromise at an unnoticeable level. On the other hand, I've never used this to force her hand.

If I know my daughter is being bullied or having trouble with a boy I wait for her to come to me or I make unassuming statements that give her the opportunity to decide if she thinks she should open up to me. Obviously if she got into something like meth the situation would be different, but in the case of things like weed or vaping I focus on topics that let her feel in control of her life because the point of parenting is imo to teach our kids to handle themselves when we're gone. For example, when she went through a weed phase I focused on noticing her grades had been slipping while stressing that I wouldn't be worrying if that hadn't been the case. The result is that she still smokes weed sometimes with friends but she's made a point to bring her grades up because she thinks it'll curb my concerns and convince me to give her more agency (which I do). To her credit, she seems to genuinely be trying to balance her peer group against the pressures I push on her and so as long as I don't think she's on a path that's destructive in the long haul I try to respect her choices.

Focusing on things like social trends or teen-tech is the wrong angle imo because the truth is that money is freedom and money comes from carefully considered action. Kids make mistakes and get hurt in hard ways sometimes, I hate that but it's the world we live in. So as long as my kid is chasing money and grades I don't mind giving her the freedom to make mistakes and get hurt (even if I hate it).
Which sounds pretty horrible if you think about it - how many of those obsolete software stacks are driving around out there without any clear notification to drivers that they're lacking in quality?
I think thats because they don't know anything more atm. CenturyLink didn't do a postmortem yet so they can only guess and see what happend. What they suggest all seems possible, but it will be guesswork until CenturyLink explains what happens (if that ever happens)

Two thoughts:

For this problem, I would use union types in Julia. Union types are a sort of sum, but they are amalgamated sums whilst sums types in PL semantics usually means disjoint sums. The difference is that disjoint sums 'mark' whether a value is of the left or right type, while with amalgamated sums the value may belong unmarked to the intersection. The distinction does not matter in the example the post gives.

Second, Julia does not give the benefit that Rust gives of type coverage, that is, ensuring that functions that take the sum type as argument actually are defined for each branch of the sum type. The Rust compiler guarantees this automatically. AFAICS, with Julia it is up to the user to provide tests exploring the branches.
Your pricing should be much higher in my opinion, something like $20-25/month, but then give those customers pretty massive access. (unlimited everything)

Doing the math here, for you to make a starter engineering salary off this project, you'd need to hit $10,000/month - which would mean around 40,000 paying basic users or 12,000 paying pro users.

If this hits the front page you'd maybe get around 50,000 hits to the site - which means your conversion needs to be around 80% (for Basic).

Whereas if you had a free plan and a pro plan that was $25/month - you'd only need 400 people. Which is a conversion of 8% from this particular traffic source.

Your call, but I think lower prices these days speak to me as the developer not being all-in on their particular product - even if you are, it's just the optics of it.

If I really need this, you can bet I'd pay $25/month for it.

The Roam Research guys do a good job at this, even if their product is not yet at 90% refinement, just the fact that they are willing to charge a higher price makes me believe they will actually put the work into it to make it better. There are students and researchers that do NOT want to bother with storing the files to build that graph, hooking up VSCode with a graph-editor addon (there are many), all they want is a thing that does what it says it does. And they pay well for it.
Of course not. We can prove things that are absolutely true. For example, we can show 2+2, with suitable definitions of 2, + and 4, always equals 4 anywhere in the universe.
Precisely. I truly have no idea how it's made it's way into CS, but I suspect it has to do with:

I think these (to the extent they are true) are just a bunch of synonyms for ad targeting, which people already intuitively understand. If an ad is targeted at you, obviously the information needed to do that has to exist somewhere. People may not know the technical terminology, but they understand it. I’m not just talking about the tech filter bubble. When I visit my rural family home, people talk to me about it. They joke about what the algorithm will think of this or that activity they do on a phone.

It’s not true that you can just buy a dossier on someone from Google or Facebook. That would make no sense, their business is rationing the use of that data by selling inferences (the gold eggs), not by selling the model (the golden goose).
This reminds me to be afraid as a blind pedestrian in this modern world of automated danger. I still remember it took me a while as a kid to begin and trust that drivers would actually see me. I think I will never trust that self-driving cars will react properly to me being blind.

Thank you for a clear explanation.
I'm a total layman here, so forgive my questions if they don't make sense:

> One of the deep insights of special relativity is that these scalar and vector quantities are actually unified into a single, new entity called a "four-vector"

On which basis was this pairing between position and time "decided"?

> But the really weird thing about this particular four-vector is that it always has a magnitude of exactly the speed of light

Why is that? Is it by definition?

> it's actually the change in coordinate time per change in proper time

How does this translate to what we call "time" in our daily lives?
> this is completely non nondiscoverable

I also don’t find this discoverable, but option clicking was best analogy to right clicking on Apple since the mouse used to have one button.

Your complaint is like saying that having to copy and paste with ctrl c and ctrl v is non discoverable in Windows with a two button mouse because in Linux it’s just select text and middle click somewhere else.
There are reprocessing schemes like pyroprocessing that are less useful for producing bomb materials. But yes, currently at industrial scale the method of choice is PUREX, which AFAIK is the same process which is used for producing Pu for weapons. Although when reprocessing high burnup spent fuel from commercial reactors you get Pu with an isotopic composition poorly suited for weapons.
Comments can get stale really fast but I probably write at least twice the amount of comments as code because that's how I reason about the function and intention of the code. Sometimes the code seems simple but the reason why it exists can be really complex.

One of my favorites is (spoiler alert) Incandescence, which presents the utterly novel concept of an alien civilization whose faculties, environment, and thought processes are totally un-human. The characters in this story very gradually discover the principles of relativity from scratch.

For me reading this book, the process of understanding what it is that they are understanding ends up conveying very little useful information of how humans understand physics -- a bizarre and thought-provoking experience.
Even enough statistics to do better in a game that uses dice or card decks would help people a lot in other aspects of life.
The article clearly implies that some or several of involved parties are ripping off taxpayers when instead the actual costs per ventilator are quite low, and not only that, the deal they're referring to wasn't even due now. That's deceptive. Even your summary is deceptive when you say stuff like "instead used that money to also design higher-cost ventilators that it actually started selling" - there seems to be 0 evidence of that occurring at least in any unreasonable sense.

Put it this way: what's there actually to report here? That a lowest-possible-cost contract for a few ventilators before 2022 didn't deliver many more before 2020? That the contract looks reasonable, and so far honestly fulfilled?

The insinuations aren't harmless. Not only because it might lead people to support more oversight and interventions where none are warranted, but also because they distract from real issues - and there are more than enough of those.

I think another factor at play here is that with remote meetings, there isn't a sunk cost in people physically travelling to the meeting room. It can feel silly to bring 4 people to a place to meet just for 4 minutes, especially if they're coming from other floors or other buildings. Remotely it feels fine. Blip in, blip out.

Almost all of the Tesla autopilot crashes could have been avoided if they used LIDAR on their cars.

But of course, if they used LIDAR on their cars, they wouldn't be able to ship hundreds of thousands of cars.
Maybe a good comparison could be nuclear fusion power plant. Correct me if I'm wrong but theoretical breakthrough took place in like the 1970's, with operational labs sized tokamak.

Yet the first test breakeven reactor ITER is 'scheduled' to operate in 2025 (if nothing goes havoc until then).

Yeah I known that software operate on different concept these day (move fast and break things) but I'm still unconvinced this could be compatible with any marketing strategy for self driving cars.

Well of course you should define the methods in DB entry, that way they can be changed as needed as business needs change. Seeing as nobody is going to be touching the absolutely sacrosanct source code, putting functions in the DB and reading them into the code base during compile and/or hot-reload is really the only reasonable way.
The are decommissioning some of the redundant VOR stations. The VOR network will remain operational as a backup to GPS. (See: "VOR minimum operational network")

When it comes to life-critical systems, you never rely on a single point of failure. GPS is potentially a single point of failure. It can and does have errors, either due to military jamming exercises, satellite failures, or other interference. I've personally had the GPS system in my aircraft completely fail due to interference.

It's also worth noting that the FAA considers VOR navigation a required skill. It's part of the core material on the test as a private pilot.
I was happy to write this, since The Great Courses have had such a big impact on my learning. I was just frustrated that what could've been a nice profile (given how much access the author had to the company and its leadership) turned into an ideological screed. IMO, Heather MacDonald sees herself and/or functions as more of a commentator/activist than journalist.

It's truly a remarkable company. It has reinvented itself multiple times: physical DVDs, online downloads, Netflix style streaming, and now audio partnerships with Audible. The recent lifestyle additions (partnerships with NatGeo and Culinary Institute of America) have been great too.

Reliably jamming drone comms would also jam all other radio based systems in the area. You could try to narrow your beam, but that could lead to evasive pattern dodge manouvers, and would be harder against a swarm of the things. Even then, the drones could get by with extremely crude, near ballistic autonomy (erraticly fly 500m in that compass direction and detonate on the moving blob near the pool).
Best way to save important stuff for me is to just email it to myself :/ Crude but effective, even with GMail's less than optimal search.

This is in the same vein as the thought-experiment about the One-Electron Universe [https://en.wikipedia.org/wiki/One-electron_universe].

The idea is, maybe everything in the universe is just 1 electron looping through 4D space over and over, interacting with itself at various points of the loop. Comes about from the observation that antimatter can be described perfectly as just regular matter moving backwards in time.
I'm not sure, but can you actually access a drive on Linux while it's being fsck'd? It sounds quite logical not to mount the drive, although perhaps one could get some mileage from mounting it RO.

> Apple completely hides what is actually going on from the user

That's intentional. I know people, ranging from barely computer-aware to MSc., who don't/can't understand what you would mean by resolution. Or exFAT. Or kill -9. However, they do know how to mess up with the slightest amount of power given to them. Hiding the system is a boon.

I'm a computer enginer, and for me, macOS is a great blend of power and simplicity/usability. I won't be happy if they mess up the OS or the hardware.
