> Novel hardware devices (e.g., for VR, or the Wii remote, or for new musical instruments) can be used as the basis for new tools for thought. While hardware can be duplicated, it’s often much more expensive than duplicating software. And, in any case, the advantage for such companies is often in distribution, marketing, and relationships with vendors who make products for the platform.

SimulaVR was heavily influenced by the early visions for computing devices as "Tools for Thought".[1]

"Computing as an intelligence augmenter" seemed to be a really popular viewpoint through the 70s and 80s (even in corporate advertisements for computing devices). Then it somehow got co-opted by "computing as a medium for passive entertainment and video games", and then eventually as "a medium for social networking". I'm certainly not against these things in all contexts, but to me the exciting thing about VR/AR is that it creates a completely open field to make new advancements in the way human beings interact with machines to get stuff done immersively & with greater creativity.

Despite this, the entire VR ecosystem seems to be focused almost exclusively on gaming/entertainment + social networking (facebook "Metaverse"). I personally find it really exciting to think about how the extra dimension could help us create more interactive tools in line with Alan Kay (& co's) early visions. Before that's possible, we first need to get the basic hardware good enough to replace PCs & Laptops (for everyday 2-dimensional applications). After that, we can these devices as platforms to build better thinking tools on.

There any studies looking for differences in outcomes between patients cared for by physicians and those cared for by other highly intelligent, capable humans with fewer years of specialized training in healthcare.

It might be interesting to examine some of this literature in the context of this thread.
Idle CPU's also use less power than ones running full tilt.
I was thinking in something similar. (I have no idea what a Ricatti equation is https://en.wikipedia.org/wiki/Riccati_equation ) Perhspas I should have said "half a dozen".

Here the first ODE course is half a semester. If you spend a week or two proving existence and unicity, you get one week to study each method and make a few examples and then you must change to next week trick.

Fourier/Laplace and other advanced stuff are in a more advanced course.

I never used perturbation theory for ODE. I've seen it for solving eigenvalues/eigenvector of operators in QN. But perhaps it's one tool I don't know.
I can look into that!
Ordinary 'investment banks' were perfectly capable and allowed to hold securities under G&S, in fact they issued more than any 'same roof' banks had (and as the wiki cite in the other thread shows, there was little structural change following repeal).
That doesn't seem to cover parasites that subsist on the food consumed by the host rather than the host itself. Tapeworms for example.
I think if you live in reality it’s pretty undeniable that Russia is doing badly in this war.

Russias man power has been so degraded they had to resort to recruiting people from prisons and forced conscription of Ukrainians in Luhansk and Donbas.

Russias heavy armour has been destroyed so badly that we are seeing T62s rolled out to the front lines. These T62s are so old they don’t even use the 3 man setup that all more modern Russian takes do because they don’t have a autoloader.

Russia is also incapable of protecting territory it has captured. The occupied territories of Ukraine regularly have car bombs and ammo depots explode, Crimea even has Russian air bases spontaneously exploding so much all Russian tourists fled back to Russia.
In The Checklist Manifesto, Atul Gawande wrote that he

...came across two professors who studied the science of complexity, which highlighted three types of problems in the world: the simple, the complicated and the complex. They are defined as:

Simple Problems – “are ones like baking a cake from a mix. There is a recipe. Sometimes there are a few basic techniques to learn. But once these are mastered, following the recipe brings a high likelihood of success.”

Complicated Problems – “are the ones like sending a rocket to the moon. They can sometimes be broken down into a series of simple problems. But there is no straightforward recipe. Success frequently requires multiple people, often multiple teams and specialized expertise. Unanticipated difficulties are frequent. Timing and coordination become serious concerns.”

Complex Problems – “are ones like raising a child. Once you learn how to send a rocket to the moon, you can repeat the process with other rockets and perfect it. One rocket is like another rocket. But not so with raising a child. Every child is unique. Although raising one child may provide experience, it does not guarantee success with the next child. Expertise is valuable but most certainly not sufficient. Indeed, the next child may require an entirely different approach from the previous one. And this brings up another feature of complex problems: their outcomes remain highly uncertain. Yet we all know that it is possible to raise a child well.”

For the longest time medicine has been part of the complex problem set. Doctors (very rightly) are highly trained with a minimum of 4 years of training followed by years of residency. The profession is seen as highly complex where they need to combine their book learning, with hands-on training and decades of experience to diagnose and treat a wide variety of health conditions. However in Low and Middle Income Countries, where doctors are in short supply, can some level of healthcare be provide by applying Artificial Intelligence to the SOAP (Subjective, Objective, Assessment, Plan) Note along with a touch of the Bayesian Priors?
Northeastern University is a college which is extremely popular for it's co-op program. What is co-op? It's literally just working at a company for 6 months. Yet students proclaim how it teaches them so much better than classes and helps them so much to get a great job, and I mean, it does.

College is the new high-school: everyone goes, only to get a job, because you have to go to college and get a CS degree to get a job. Why? A lot of "compute science" isn't used in software development at all.

I think we should replace colleges with "boot camps" which are unpaid internships which teach high schoolers how to work in actual software development, in various fields (let's call them "entry level jobs which don't require 5 years of experience"). Why unpaid? Because companies will love it, and it will still be better than colleges where you pay a full year's salary in tuition.

What about people who actually want to pursue higher-ed computer science? Just don't replace all colleges. It seems like most people getting into CS are not doing it for academia, those that are will have a better time taking courses with others who are passionate about the subject instead of simply using it to get a high-paying job.
Huh, TIL. There are two or three shows that I just stopped bothering with altogether on Hulu and have been torrenting for years because of those ads, while we used Hulu for shows that didn't have any ads at all. I wish their communication around this had been stronger, I wonder how long ago I would've stopped pirating them.

Thanks for pointing that out! (And I should dig into those details the next time I share links like that)
I just looked it up: Even if you accept less than 1 GB you'll have a hard time finding drives below $3. The USB controller chip alone is about $1 and you need some actual storage and a casing as well. Even if you're really proficient at acquisition and manage to get them for 10% of that price, it's still orders of magnitude more expensive than email based spam.
The SOAP note (an acronym for subjective, objective, assessment, and plan)is a methodology for documenting a patient's condition on first examination by a medical professional. It serves as an excellent cognitive framework for medical professional to assess their patients.

The SOAP Note originated from the early work done by Dr. Lawrence Weed (an American physician, researcher, educator, entrepreneur and author, who is best known for creating the problem-oriented medical record as well as one of the first electronic health records).

SOAP notes are commonly found in Electronic Medical Records as a means to succinctly communicate patient information in a standard format and are particularly useful between hand-offs between medical professionals.

Modern Electronic Health Record (EHR) Systems offer a great deal more in terms of adding additional diagnostic information as well as a longitudinal patient record but the basics SOAP note could prove immensely valuable as we think about how to design a system that can empower Community Health Workers (CHWs).

SOAP Note in Practice (highly simplified for an illustrative example)

Situation: A medical professional encounters an individual who seeks or is identified for medical care

Subjective data collection

Shaking chills

Muscle ache

Fatigue

Objective data collection

Fever of 102 F (suing a Bluetooth connected thermometer or a cell phone camera based temperature detector)

Malaria Rapid Diagnostic Test (RDT) administered - shows positive

Assessment

The Subjective and Objective information is collated in the medical professionals mind and and she assesses that the patient shows indications of Malaria

Plan

Based on the Subjective and Objective and informed by the Assessment, the medical professional develops a Plan that is specific to the situational context - in this case it may involve sending the patient for a confirmatory Malaria confirmatory test or in some cases starting them directly on anti-malarial treatment.

The SOAP note allows a complicated problem to be broken down into components to then become a simple problem. However, in Global Health today, this complicated problem is treated as a complex problem because it is felt that only a doctor with decades of experience and a medical degree would be able to accurately diagnose and treat Malaria.
Eh, I think it’s naive to believe that greed is sufficient protection. Owning a bunch of ETH so you can set ETH on fire would be a waste of money, only so long as the person setting the fire didn’t value the mischief more than the ETH. I don’t see why nation states wouldn’t attack each other by burning down the crypto assets of citizens, either.
This is a myth.

Netflix's DRM is sufficiently good that the Reddit Piracy subreddit has spent the last three months moaning that they have no access to 4K Netflix rips, at least for weeks or months after the content comes out.

Netflix's DRM and key management systems do what they care about pretty well at this point, which is protect the initial airing of popular shows.
Yah I imagine they would. What other productive industries could replace them I wonder.

Usually the top priorities at a research university are:

1. Fundraising.
2. Research (in support of 1)

In the humanities, tenure track positions usually only open up when someone dies or retires, assuming the slot is not also retired, and there will be hundreds of applicants for each position.

The academic pyramid is unsustainable since faculty usually supervise (and graduate) multiple Ph.D. students before dying or retiring.

But it is disappointing to hear that Yale's "tenure track" has a high failure rate. It seems like an incredible waste of people's lives.
Just a guess, but before everybody adopted ARM the ST20 that was inherited from Inmos was ST's high end microprocessor, though they had a bunch of other families with 8 bits and such.

> 1/x also has a singularity, but as far as I'm aware, it's a perfectly normal function.

No one integrates it over 0, but they do the delta function.

> I recall that in my analysis class, they wanted to define the dirac delta as the limit of a sequence of functions.

In my engineering courses, they often tried to make it a limit of the "rectangle" function. Consider a function that is 0 everywhere except between [-delta, delta], where its value is whatever is needed to make the area under this rectangle 1. Then let delta approach 0.

This definition still fails using the standard limits/analysis that is taught (convergence problems, etc). In mathematics, the delta function needs the theory of distributions to "work".

I thought this, and then my mom got scammed. She realized one day later, and the bank was able to recover the portion sent via bank transfer. But they also tricked her into sending money via bitcoin ATMs, and that portion was not recovered.

I think that a lot of the purposeful exaggeration of these smokescreen like issues everywhere, are not necessarily with an ulterior motive, but in a banal sense, just to make things more interesting to read or make the person or company reporting about the issue, seem more interesting and just for fighting these made up paper monsters.
You're describing volumetric video, but from a single frame rather than multiple capture.

We were pitching this as the future of video about 4 years ago when raising funding for https://ayvri.com - suggesting that we have the data of where somebody was, and what the world was like around them. With a photo or video of the person, we could re-create a complete scene and you'd have a capture of essentially every angle.

Everyone said I was crazy, but what we're seeing with this sort of research, along with 3D scene recreation from a single photo and generative environments, it's definitely going to happen. I was saying it would take 5 years, 4 years ago. I'd say it is still 4-5 years from being a commercial technology.

And no, we don't actively work on Ayvri anymore. The team has moved on (started something new), we were too early. It's a good lesson.
It's volumetric data, so you can use marching cubes to extract a mesh. Nvidia has also released nvdiffrec with the explicit goal of generating meshes, materials, and lighting.

One problem with this - speculative assets are at least partially valuable because of their volatility - their ability to appreciate quickly. Even if eth is untrusted for long term value, so long as it has the potential to make money for someone in the short term it's going to continue to get transactions.

And, as always, sometimes folks just want to watch the world burn. It's a relatively low investment (~$50k) to become a validator, and the fine's only about $7k (.5 eth).

Imagine the damage someone with a few million (say, some baby-boomer who just sold their California duplex) could do if they wanted to.
PoS is less proven than PoW and has some edges cases that give many concerns. To say this up front, I own ETH, have worked on dapps on it, and completely supprt the move to PoS.

That said, the fact that PoW has been running the longest and Bitcoin uses it to secure the most value of any chain and it has had 100% uptime for the last 9.5 years, means people naturally trust it more.

PoS also in theory incentivizes centralization of staking over time. It's already started to play out this way way with the top two stakers controlling 46% of the staked ETH on the Beacon Chain. With Bitcoin, because you constantly have to buy new hardware and find cheap energy every single block, there's been a constant rise and fall of large miners.

A related issue is that it's more fragile to government censorship as the Tornado Cash OFAC sanctions show. Bitcoin has had mixers sanctioned and it didn't affect the core chain at all. With Tornado Cash, it's possible that Coinbase and other US-based stakers will have to not validate certain transactions, which doesn’t work in PoS, so they've said they will stop staking if the US gov't decides OFAC applies to stakers (which there's a legal argument it does). It's a bit in the weeds, but basically Bitcoin/PoW works in a fundamentally different way, so miners can filter out transactions they legally aren't allow to process and all that happens is those transactions get validated in a future block by other miners.

One other is that PoS has no deterministic way to recover from a complete outage. If a huge EMP brought down every computer network on Earth, when they come back online, PoW has a clear rule for determining which chain is the real one. PoS does not, so it's unclear what would happen. This may seem like a small edge case, and it is, but trust and security are so important when $500B and growing is at stake that tiny edge cases matter.

Luckily there are many interesting examples that can be solved. In particular the linear differential equations. Many equations can be approximated by a linear version of it.

Also, in Physics, a lot of ODE are mysteriously integrable if the variable is x instead of t. (One reason is that it's easy to measure the force/fields, but the "real" thing are the potential, so you are measuring the derivative of a hopefully nice object.)

Also a lot of the theoretical advanced stuff to prove analytical solutions and to estimate the error in the numerical integrations use the kind of stuff you learn solving the easy examples analytically.

And also historical reasons. We have less than 100 years of easy numerical integrations, and the math curriculum advance slowly. Anyway, I've seen a reduction in the coverage of the most weird stuff like the substitution θ=atan(x/2) (or something like that, I always forget the details). It's very useful for some integrals with too many sin and cos, but it's not very insightful, so it's good to offload it to Wolfram Alpha.
Yes, I noticed this after I posted. Small errors like this become common when instructions reach this length. It randomly forgets to do steps that aren’t written down — it never leaves things blank, but it forgets pieces of compound directions.

I also suspect it was confused by the fact the name was abbreviated but not misspelled, and it was only told explicitly to ensure names are not misspelled. Still an error though.
I'm implying their popular because they're familiar, that was how my first post started. People get comfortable with things forced upon them too.

Lets face it: There is so much theory crammed into some CS degrees, bachelor and master degrees, that students do not get to code much. Real coding is often learned by oneself in side projects or on the job. If students do not engage in side projects, how do we expect them to be proficient computer programmers out of university?

However, I see this as a failure of CS education. Our work is with computers. If we do not teach, how to use the tool we work with properly, then we have failed. I know CS is not only developing software, but also a lot about the theory, but it should not exclude practice of working with the most commonly used tool, which graduates will use, the computer.

Often even things are taught wrongly (do not get me started on "every noun is a class" kind of teaching of OOP), by people, who have not developed a single larger code base for decades.

That said, the industry has at least in that regard caught up a bit, and realized, that fresh from university most people do not write good code immediately.

I think it's funny that I got downvoted for this! For full clarity: I wasn't suggesting that they _shouldn't_ be called debug tooling, just that it's not what I would call that class of feature, and it seems that other people do call it that.

We spent decades being gaslit (heh) by pro-hydrocarbon stooges who swore that renewables could never ever work, citing junk statistics they carefully curated or just outright fabricated, and then PV panel production really ramped and proved them to be liars, and they all moved on to the next thing. What is true is that the oil and gas industry is going to kick and scream the entire way as the human race tries to wean itself from this addiction, and it doesn't matter how many animals die, how many glaciers melt or rivers run dry, they do not care.
Yeah, I’ve not seen anything that I love there unfortunately. Ton for the former, but not much for the later. I’ve thought of trying to create it, but I know how hard it is to produce great content and how unrewarding it is.

Checkpoint is a deploy system, not a CICD. A quick Google finds a nice description of it: https://slack.engineering/deploys-at-slack/

That said, once you step away from webapp world, a lot of times all existing CI/CD systems are pretty terrible. For example we have pre-merge tests that need a few tens of cpu-hours spread across a dozen machines, and running natively (no docker). This rules out pretty much every CI/CD system out there except Jenkins and Buildkite, and both of them a pretty horrible at it unless you spend lots of time with custom scripts. At some point it will become easier to rewrite entire system rather than try to fight existing one.
