Soton is in an entirely different league to MMU.

Textile making isn't an academic discipline, and historically would not have been taught at a university at all. If you want high quality academic research and rigour, you're far more likely to find it somewhere other than MMU.

This is an unfortunate truth, but a truth nonetheless.

Presumably they'd have to be rewritten, but if you're talking a new OS anyway everything's gotten be rewritten, because you won't have the standard UNIX syscalls. This is not something to embark on lightly, which is why I haven't embarked on it yet.

But imagine a future where using a traditional OS means there's close to a 100% chance that you will have your identity and/or financial assets stolen, or where these computers are widely used in the military and a security failure literally means you're dead. We're headed there anyway, judging from all the headlines on data breaches and identity theft. There'll be system failure at that point, as well as a strong incentive to rewrite everything as a secure system.

How to think about stock options
Climate change is the biggest opportunity civilization has ever seen, and I'm happy to share that view with others that might contribute.

Appreciate your thoughts on this! You make a great point about LED bulbs and their landfill potential.

You're totally right about the fixed costs of LEDs. Today they're very complex from a manufacturing and materials standpoint, and can create much more trouble at a landfill than old glass and wire bulbs. That's a huge opportunity for improvement.

Ultimately as a civilization we have to find solutions with the lowest fixed and variable costs. The variable cost of glass and wire bulbs is high. You're heating a wire and generating tons of lost heat. LEDs beat the pants of glass and wire bulbs in terms of efficiency. So we have to improve that up front manufacturing and landfill potential of LEDs.
I'm asking out of ignorance. You're using the word "solutions". Do we know those are really "solutions", and not guesses for solutions? Like, will those actions reduce temperatures?

It seems that some of what already happened, like melting of icebergs, is not easy to be revert.
A carbon tax is just massive scam built around this fear of global warning.
(another Physics Ph.D. here)

Solving a problem in physics or math generally implies a closed form solution. Which this is, decidedly, not. It is in fact a special case, with low particle count, and doesn't return velocity information, thus leading to problems assessing whether some things like Energy, are actually conserved.

They discuss this. And have to use a second network to compute velocity, used for computing kinetic energy. In which they discover that in close near-collision dynamics, their error can spike. Unless they reproject the phase space coordinates specifically atop the "right" constant energy surface.

So ... yeah ... title of preprint is quite misleading. Their conclusions are also misleading.

Are they better/more general at numeric solution for arbitrary mass, arbitrary particle count, arbitrary initial conditions than, say, a good symplectic integrator of high order?

No. Actually they only studied the equal mass case of 3 particles. Given the combinatorics, I could not fathom the size of the training set they'd need for N(particles) of any reasonable size.

There they would start having to look into some of the approximations that the simulation folks have been using for a long ... long time. Just to get their training cost down far enough to be useful.

An example. Take a simulation with N ~ 10<sup>6</sup>. 1 Million objects. Take a mass distribution in a Poissonian distribution, or an EVD, or similar. Make it similar to approximate stellar masses. Create your initial conditions and generate your training sets from these initial conditions. How many of these simulations would you need to run, and for how long, in order to be able to get something which provided long time scale prediction, which meshed with reality?

Oh, take N at least 8 for planetary mass distribution. With satellites, so N ~ 200. Never mind planetary rings or Oort cloud/Kuiper belt/asteroid belt objects.

How does large does your training need to grow in order to be able to predict, with any degree of accuracy, orbital stability over gigayear intervals?

My point is not to beat on the authors, but to point out that this study, while interesting, is most definitely not a solution to the 3 body problem. There is vast literature on solutions to N-body problems in general. These problems are considered hard. Because, they actually are. There are some "short cuts", basically field-like approximations, that one can use to make some generally reasonable arguments about the interaction with many distant objects. They actual dynamics, and details of Poincare maps and phase space portraits are, again, very well studied phenomenon. With 100+ years of research behind this.

If they wanted a simpler dynamic problem to work with, the double pendulum exhibits chaotic behaviour. All they need to vary are 2 parameters for each arm/mass, length and mass. See how close they come to actual behavior, onset of trajectory divergence, etc.

[edit: slight clarification of second network computing velocity for kinetic energy]
Honestly I don't use it so often, but it seems that any query in graphql could be easily and automatically translated to a SQL query. Am I wrong?

There are definitely trying to solve the same problem, aren't they? What are the advantages of GraphQL over SQL?

Please, I really want to know the answer to this question.

The previous answer was "the infrastructure we build around GraphQL is better for microservices", ok I can see that. But it is the only answer? It seems like a little weak reason to create a language so that later you can create a new infrastructure around it.

Am I missing something?

Why you don't find GraphQL similar to SQL?
> And we’re actually going to have […] ‘installathons,’ ” Musk said, which will pit two teams against each other to see who can roof one of two similar-sized/designed roofs faster. Musk reiterated later that there’s “quite a bit of R&D just in the installation process itself.”

Not a short seller, but that sounds a lot like: “We don’t yet know how to do this well, but in the meantime we are going to optimize for speed.” This may look good to investors, but homeowners might cringe. Did Musk learn nothing from the pre-Titan installs? Somebody get him a copy of _The Mythical Man-Month_. This quote alone took me from possible early-adopter to wanting to wait 3 to 5 years until they decide to optimize installation for correctness and lowered risk of ignition.
> but the presentation is not

You are very wrong here. It is the very presentation in those books viz; succinct and concise, no frills approach, high information density and with an eye to applications which makes them so valuable today. It is the best way of Science teaching distilled from the brains of a whole lot of smart people.

I am not sure why you are fixated on one book of tables. It is irrelevant in the broader scheme of things. For example none of the Mir books that i have, have anything to do with pre-calculated tables other than a few appendices.

There are a huge swath of students across the world who do not have the same access to technology as we do. Printed books are still the norm amongst the majority of students in the world. Printed books will also outlast any Digital media presentation of books due to its simplicity and robustness i.e no problems like DRM, unreadable extinct formats, availability of good ereaders, health aspects, etc (there is a whole lot more i can elaborate here).

Finally, and most important, research is beginning to show that we retain/understand less when using ebooks/ereaders than when we read a printed book. This is very much true of technical books (borne out by my own experience) where you need concentrated attention with body and mind. For example, we intuitively jump back and forth across pages, use our fingers as book marks, subconsciously create spatial maps of what we are reading etc. all of which have no analogues with current day ereaders. Cognitive Science is still trying to figure out how best to use modern technology. So don't throw away your old Maths books just yet :-)
That means the person is liable for their mental state correct? As in they could have taken actions to prevent that situation but they intentionally chose not to?

With possession laws and statutory rape for example, the liability is that a reasonable person is expected by law to take steps to prevent their posession of co trolled substance or in case of statutory rape to discover the age of their partner. Intent does not need to be proven because the law (controversialy) defines the action to be sufficient proof of criminal intent.

Case in point: a mentally handicapped person or a small child cannot be convicted of these crimes, even under strict liability because they are incapable of criminal intent(and therefore criminal liability). even with intent or strict liability identical to that of a sane reasonable person,their inability to reason sufficiently means their intent is not considered criminal. I say that as argument that if strict liability has nothing to do with intent then inability to reason is irrelevant,because if for example mental handicap exempts a person of strict liability,it is because they are not behaving with reason and awareness of their actions and intent right? Or if someone (say a policeman) throws a bag of cocaine at you and you catch it,are you liable under strict liability? (Not being rhetorical,Honestly curious)

Strict liability does mean intent does not need to be proven but only because the law defines the action sufficient proof of criminal intent. If you can defend against this "proof" ,will you still be liable? I mean, it is my understanding that if you prove someone planted drugs to frame you or that your sexual partner showed fraudulent evidence (fake ID for example) of their age you will not be held liable, is that not the case?

Hypervisor on hypervisor makes sense if you care about security. Your average FaaS-on-Kubernetes hosting services not from one of the tech giants is a far cry from AWS Firecracker (Lambda) level of isolation. E.g. you run a gaming server and wants to allow arbitrary user plugins, or perhaps a challenger fintech bank that wants some simple user scripting. You want to allow Python/Ruby/any lang except Lua/JS/WASM. You won't be able to find anything hosted that doesn't cost an arm and a leg. (On an unrelated note, if anyone from Zeit is reading this, can you comment on why now.sh container support was deprecated in V2? Was it because of cost?)
I use vim binding in the shell a lot, typically for stringing a bunch of commands together. For replacing one word would using the `^` work?

Without criticizing the article at all, I want to point out that headlines like this go viral and make money, while the opposite ones would go nowhere.

In other words, the news you see is selected by virality, not by how well they describe the real world.

I use the following stack:

3. I use a custom Alfred workflow which uses riggrep to search very quickly through the notes.

One thing to mention is that I want my stack to be private, so this doesn't publish anything to the web but it does sync.

there are other interesting variations to this.

PostgREST is a project that does that automatically for PostgreSQL. It takes your schema of your db and creates an api based on table relationships and provides security through a database design pattern of enforcing row level security. Side effects are challenging.

I'm baffled. You "expect" something that you say you have no reason to expect, and you hope this expectation is wrong. Is this some new meaning of "expect" that I'm not familiar with? Or do you follow a psychological strategy of expecting bad things so that you'll always be pleasantly surprised?

Picture in your mind if you will, what 1600 iPads all downloading a 6 GB iOS update over a 150 Mbit (~19 MBytes/sec) link at once might do to a network. Now compare that to a gigabit (125 MByte/sec) link to our Mac Pro and 9.6 TByte saving in internet quota.

To claim any tax is a “scam” is to misunderstand tax.
No, the tax makes sense, buying and selling carbon offsets is the scam. We tried it before and it made people alike Al Gore billionaires, but was definitely a huge scam and resulting in nothing but the public getting fleeced and did jack and shite to reduce CO2.
Who said that billions are gonna die?

Frankly, if the solution to climate change will slow economic growth, I think that the highest human cost will come from the lack of growth. To put it in clear terms: lack of growth means that a sewage system, or a hospital, don't get built. This _will_ cause victims.

C# Intermediate Course: Classes and Objects Part 1
I didn’t see this response, apologies.

It seems you keep referencing: marginal cost == value. That’s very untrue. Indeed marginal cost is a factor in value, but is most certainly not directly relational.

Simply put, value is ascertained by a product’s measure of overall impact. An example would be a simple script that tally’s an employee’s hours from clock in and clock out times. Say a task that once took a bookkeeper an hour to do, with the script takes .1 seconds.

Let’s say the script cost $5 to create but zero dollars to duplicate. It doesn’t mean it’s value is zero. It’s value is equivalently equal to the hour of bookkeeping time that person saved multiplied by however many times the task is used in any given time frame.

Marginal Cost is 0. But the value is far from it. A similar exercise is done to evaluate the value of entertainment. Different factors, but same idea.

I don't know who you specifically work for but I've been to 2 different banking tech conferences in the past month. JPMorgan mentioned they have 13 (or was it 16?) wholly owned datacenters. BoA's tech summit was just this past week in Palo Alto and they were highly negative of anything public cloud. For them it is an extremely rare thing for them to put anything in public cloud. A point they stressed throughout the summit is that the main thing they sell is 'trust' (eg: by holding people's money) and that is quite simply not something they are willing to delegate to others and that's the main driver for them but of course all the other things like cost, security, regulatory, and data gravity are drivers as well.
I think the difference is still that many dot-com era companies didn't have much or any revenues, definitely not in billions.
