Photobiomodulation seems promising

PHOTOBIOMODULATION IN INHERITED RETINAL DEGENERATION (2012)

"A growing body of evidence indicates that exposure of tissue to low energy photon irradiation in the far-red to near-infrared (NIR) range of the spectrum, (photobiomodulation or PBM) acts on mitochondria-mediated signaling pathways to attenuate oxidative stress and prevent cell death. "

I'd say live chat and many concurrent users (+ many small messages being sent around) is exactly the kind of thing that Phoenix (and LiveView, and Elixir) is basically made for.
I really hoped this is what EC2 spot instances would be, but it doesn't seem to work that way. My spot instances usually get terminated due to "no available capacity" without any major price movement.

It would also be pretty neat to integrate processing power markets with the wholesale energy markets. Energy prices are quite volatile and making load responsive to that would actually be quite helpful to stabilize them.

I've always wondered how super old cities like Athens and Rome deal with infrastructure. I mean, if you need to install new sewer or cabling systems underground you're dealing with literally thousands of years of stuff under the city, and I'm guessing there is no good documentation for what's there. How do civil engineers know where it's safe to build?

I think PHP will end up being the BASIC of our generation. It was so easy to pickup and understand. The fact that it was really a templating language helped people make that jump from static HTML -> programming in small increments. And once you knew PHP, you weren't locked into web-dev. You could easily leverage your knowledge into systems development; I think roughly 40% of my PHP work ended up being backend utilities for Linux.
I use my quest every day and my kids love it.
I personally think the most relevant courses I took were an OS course (I don't write operating systems, but knowing how they work can be very important) and algorithms come up rarely, but still sometimes. I also had a networking course that I definitely benefited from. Generally, I am quite pleased with my education.
I don't know, those could be genuine feelings. Like the first time using VR.

I think the biggest hurdle would be the Functional Programming aspects. Elixir was quite easy for me to approach coming from mostly PHP, Node.js and Python (preferred Python before Elixir).

Phoenix has a sprinkling of magic or syntactic sugar through macros and stuff but the step between Phoenix and LiveView is not that mystical to me.

I have taught a novice developer, not yet out of 2-year school for web dev, to use Elixir and the Phoenix Framework. I really should interview him about that. Write something up.

I would say that Django does more stuff under the hood than Phoenix. But they are fairly different vehicles.

Is there some reason to think Cuban has some useful thoughts here?

He has done well for himself but he seems more than willing to make quips well outside of his knowledge base. Specifically I'm thinking of some off the cuff tweets regarding personal healthcare that seemed to be pretty far off base.

Maybe that was a one off thing but I recall some others even regarding personal finance that seemed questionable.
I don’t think that the ‘ploughed salt’ approach is considered true anymore. The articles I want to link to are paywalled but there is a good discussion in the below reddit thread. The tldr is the salt was very expensive.

But as I pointed out in the original post - the 10B in fees is in line with revenue the banks receive during normal times. And going off the earnings the banks posted last week, they are losing millions every day just keeping the lights on.

There is no increased earnings there is in fact very big losses. Which is another thing people tend to forget when discussing exec pay. The execs take a hit when business is bad, but the majority of employees continue getting paid.

Exec pay is high but you can't forget that much of the risk / responsibility should the business do poorly is on their heads not the majority of the workforce.
Current employee here. The employee count is actually 7000, half of what you stated. Not sure where you got 14,000.
Looking at the README of vim-gitgutter[1] (assuming that's the plugin you're referring to), it says the following:

>> You cannot unstage a staged hunk.

I'm not sure if that's a feature they plan to support, but something like this could easily be done by highlighting the hunk displayed when running git diff --cached in vim's linewise visual mode and filtering it through git apply -R --cached -.

> Are you saying the US is incapable of doing what is already being done in many other countries?

"Incapable" assumes lots of things, but practically speaking the number of things that we (the USA) "are capable of doing" is shrinking and using GDP/Person is an interesting way to illustrate the point.

We are overpaying for services that other countries have managed to solve for reasonable costs. University tuition, healthcare, building infrastructure are all ridiculously expensive in the USA, so our higher GDP/Person is largely wasted compared to most other OECD countries. Our government and the crooked ethical guidelines of our companies/organizations are why this overpricing started and continues to exist.

For those tasks which require regulatory/legal changes, the USA is swimming in peanut butter. What we "are capable of doing" largely has to do with our Legislature+Executive branches ability to find ways to make productive changes (rare) without sabotaging those same efforts (even rarer). But half of those people are rowing in one direction (team red) and the other half in another (team blue). The USA's primary policy tool is "make the most visible spectacle of brinksmanship" and has been for 10+ years.

The people/companies in the USA are capable of feature parity with just about any other country's people/companies, but that assumes that our government either doesn't get in the way or their government doesn't assist them.
Pretty much. All
of these tricks are meant to cover for gaps in pay or toxic environments. If you want me to be “productive” spare the “motivational” bs and give me the tools i need to get the job done, pay according to my contribution and keep politics away. Everything else are stories for naive junior staff.
It's completely relevant. People run more than one application on their desktop computers.

Regardless of what many people say, RAM usage still matters. If every app takes a giant chunk of RAM just to get started ( which many do ) eventually that's going to bite you.

Yes, we do have a ton more resources to work with than we used to, but I'm afraid far too many developers have just stopped caring about it at all -- and that's a very bad thing.
This is tiring. Can you confirm that you understand or do not the difference between what the Vedas declare about varna dharma and how it has been abused? This core point you continue to either ignore or not comprehend. Your entire argument is useless because it continues to be based on the misapplication of varna dharma, which I agree, is not good.

> By the way Britishers never had religion as part of education.

That is utterly, laughably, ridiculously false. I can't believe someone with even a modicum of intelligence would say that.

If you don't believe in karma that's fine, but whether you believe in it or not doesn't mean you continue to state false things about the Vedas. One can have a correct understanding of something without necessarily believing in it. But your understanding has been incorrect this entire thread, where I've each time pointed to the difference between what the Vedas declare in contrast to what people have done. This difference you can't seem to grasp.
It's a classic observation bias.

If you're a programmer who doesn't know any CS, you are likely unaware of what you don't know. Googling for what you don't know is remarkably unuseful.
Way better? I spent a week in both Georgia and Armenia recently and although I think the two counties are some of the coolest places I've been I found Armenia to be more interesting. That may have been because I had a local guide in Armenia though. (I like to travel with Couchsurfing as you get to meet and stay with locals, and for whatever reason Georgia is the only country I've visited where I couldn't find a host.)

In particular, I spent a day in Kutaisi and although it was a lovely little place I didn't find it super interesting.

I'll definitely be back though, I hadn't heard of Mtskheta and it seems really interesting, I'd like to check it out.

I assume you're Georgian, from the name :) Any other places you'd suggest to visit in Georgia? I personally prefer the really unusual/out of the way stuff myself.

Let's just imagine that you are a water supply company for a medium sized city with $1,000,000/month in revenue. Let's further imagine that all of your "business demand", which is normally 50% of your business, has dried up while you residential demand has gone up 50%, so you are running at 75%. And let's pretend that you have fixed costs and previously had a 10% profit margin.

Whereas before you were making $100,000/month profit, now you are losing $150,000/month. Now, let's say you run out of money to pay your employees and can't raise more.

If you shut down, the city can't have water. If you stay open, your costs and employees can't get paid. If you close down and your creditors take over you, they'll have the same issue. So what do you do? I'd argue a government bailout in this case is necessary. There's a whole other question of how punitive the bailout should be. Does the government lend you money, take partial ownership or take full ownership outright? But I think most people agree that something needs to get done.
Perhaps they're big in SF, but they exist basically nowhere else in numbers that matter in any way (aside from those super weird Segway tours in like D.C.). Sometimes the tech itself just isn't that good, and sometimes it's a bad idea.
> Everything a typical programmer does can be learned with just a textbook and/or the Internet.

You are absolutely right. Literally every single thing a programmer does, every bit of information they use, and every other thing they might use or need to know can be found beyond the ivory tower. It's all there. In fact, often the problem is less getting information and more figuring out what information is relevant.

Is it possible that some people may find value in a structured educational process? One that has already organized and worked out how to teach the fundamentals? I suspect that many people, pointed at the internet in general, may experience some difficulty in figuring out what to study and in what order.

As for material, I've personally found DFAs, FSMs, algorithmic analysis, and an understanding of computer architecture to be valuable to my career. I found a lot of basic theory useless, until I encountered cryptography that required me to understand a lot of theory to grasp fully. Obviously, personal mileage can, does, and will vary greatly.
They had a few-hundred-pound cart-bound prototype called The Beast that was supposedly mind blowing to use, and that's what convinced a lot of engineers to drop everything and move to Florida to work on it. I agree pushing that technical narrative would have sounded much better.

Suppose I'm building a new datacenter that I want to do some constant amount of work each day. It doesn't matter the time of day. I can either power it with solar power, in which case it will run for 1/Y of the day, or with coal power, in which case it will run 100% of the day. If it only runs for 1/Y of the day, then I will need to buy Y times as many computers in the solar scenario than in the coal scenario.

If Y = 2 and only 16% of the carbon in a typical coal-powered computer's lifetime is from the manufacture, then solar makes sense - solar is 2*16% = 32% of the carbon of coal. But if Y = 10 - so it's running 10% of the time, meaning there need to be 10x as many computers built - and 16% of the carbon is from the manufacture, then solar power is actually worse for the environment than coal power: solar takes 60% more carbon than coal power.

Of course, this is a vastly simplified situation, but it points to the idea that we need to at least consider the carbon cost of manufacturing.

Basically a meta-layer for the real world that you can interact with outside of a screen. This would let you do things like interact with a lightswitch from across the room by looking at it, get metadata about most object states by looking at it, anchor big displays to white walls, etc.

I think there's huge potential for this kind of interface, but I suspect the hardware isn't possible yet.

Some of my coworkers brought up the story of NASA's renegade "Pirate Paradigm" that upset the status quo and busted through bureaucratic barriers before Agile was in vogue. [0] It's a true story of a group of young engineers that created a new system for mission control that would enable missions for years to come, while the thought of it was lambasted by management.

But one quote that popped out to me was:

> By taking action that challenged the established culture of their organization, the Pirates innovated new mission control capabilities for NASA, resulting in the group’s first project, Real-Time Data Systems (RTDS), which took a year’s worth of off-hours time to create.

>>>>Which took a year's worth of off-hours time to create.

So the team performed this groundbreaking work with no extra pay, on top of their other duties. This was construed to be inspirational among my coworkers who brought it up. I can see it. It is really awesome, and I bet those engineers felt like they were on top of the world.

But to me, this is almost crazy to think that - in today's world - working for a large business the size of NASA that you wouldn't be fairly compensated while doing such immensely valuable work far above your personal scope of duty - even if you have the best coworkers or love your work. Sure, in several industries this happens all the time (especially startups, where founders perform immense amounts of work with no pay with the hope of hitting gold), but in the big corporate, government, and defense contracting worlds this is not only discouraged, but often disallowed.

To add to this, it's worth noting that Elixir would have difficulty _ever_ becoming statically typed because of how message-passing works. For example, if you look at Gleam [0] -- the recent project that's trying to create a statically typed language for the BEAM -- it can't handle message-passing [1].

And I totally agree with you here:

> I've found that it's possible to pretend it is a statically typed language if you squint just right.

My Elixir code tends to use a lot of pattern matching on structs. It's not real static typing, but it gets me a lot of mileage!

Writing a thesis in a Nazi concentration camp
My rift CV1 just got a firmware update this week.
"Within the scope of developing reinforcement learning (RL) algorithms, the goal is to build agents that learn to achieve the given objective."

This is the fundamental problem. That is not the goal. As long as people believe that is the goal we will not advance.

Put another way, "the given objective" to date has always been wrong. All of the desired behavior that we are trying to get machines to emulate is a tiny subset of the learned behaviors of the capable agents (us).

The primary object we have is to survive. On a moment to moment basis our object is to fulfill a set of competing needs (hunger, tiredness, boredom etc). It is the interplay of these multiple objectives with an complex environment which necessitates the kind of intelligence that we have.

And to be absolutely clear the answer to "How do we faithfully capture the human concept of a given task in a reward function?" is "You don't" and trying to do so is harmful to the research effort.

The correct path is to evolve a reward system which functions to increase the frequencies of behaviors which meet the needs of agents in the moment and fulfill the general goal of survival. Then through a curriculum of environmental challenges* allow for those needs to only be met by accomplishing certain tasks which have value, or are of interest, to us.

*Simulator fidelity / hacking will continue to be a problem, but it is orthogonal to the problem of RL. RL finds the bugs, you fix them.
> 'nerdy' (a word that doesn't even have an equivalent in Russian)

I wonder how many languages actually do have an equivalent. Maybe English is the only one?

When I translate something to Slovak, I also struggle with the word 'nerd'. We do not have a word for this concept. A close one is "bifľoš", which means a person who puts a lot of effort into memorizing school material, but it is implied that the person does not truly understand it. Another one is "kockáč", which means a math-oriented person. But we do not have a word that means: a weird person, because they actually study and understand something.

To me it seems that America is like "no child left behind", while Russia and Eastern Europe are like "if a child gets behind, wolves will eat them, who cares, at least it motivates others to run faster". :D
Confirm. LiveView will apply css loading state classes, which are user defined, but we generated css by default in new apps to lock the UI with loading cursor, and show a top loading bar. On reconnect, which happens automatically, we rematch the DOM with any changes, and we also send up any user form input beforehand so client state is lost that was in progress. We already have reports of users pushing bugs to their systems and the UI seemingly being unaffected because the LiveViews automatically recover, wether from a disconnect or a crash on the server.
Computing had been in the works since Babbage, over hundreds of years. Once the tech was in place there was infinite jobs to be had making sure humanity could democratize and exploit computing to it's highest potential.

What's coming down the hundreds-of-years pipe that we can bust open for this half-century? The 40s were famously the fighting forties, if we don't get on it we're going to be forced to take what others have in an attempt to access the infinite or stave off nihilism.

Nukes are underutilized but likely to be surpassed by fusion if the recent builds and smaller experiments pay off. With infinite computing power and orders of magnitude cheaper energy we employ everybody to do the same as before but bigger and better. Material science could unlock a bunch of new avenues for improvement. Biomed is kicking off but that's unlikely to employ everybody. I can't see it all, there's gotta be something.

The IRS already has the information that the banks are asking for.

For companies with employees, that is IRS Forms 940 and 941.

For Sole Props that is your IRS Form 1040 and Schedule-C.

The IRS likely has the banking information for your company (or your payroll processor) and if they don't they have your business address, and could cut checks like they do EVERY YEAR.

Claiming that a bank has to be there to process the paperwork is just plain ignorant of the amount of information the IRS already requires from companies on a quarterly and yearly basis.
