Color convergence on large CRT monitors is problematic. Back in the early 90s I spent $1200 out of my own pocket to buy a 20" CRT. At the time I was designing 3D rasterization algorithms and circuits and would spend hundreds of hours tweaking constants (how much difference loss does a 5b interpolation fraction introduce vs 6b, etc) and A/B testing to get the most cost effective & high quality results.

I bought and returned two and just lived with the defects of the 3rd one when I realized it was impossible to get good convergence across the display. I would confine my A/B tests to a specific area of the screen where convergence was best.

BTW, I forget the exact details, but color convergence at the factory was set with the monitor facing some particular direction, lets say north. If you set up the monitor facing east, the convergence would be off a little bit.

When quality LCDs became available, convergence was a non-issue, but they used dithering to attempt to increase the color gradations, so it didn't really help my kind of work anyway.
I agree. There is an implied assumption in the original post that people have the capacity to use that extra time for learning. If you are mentally drained from work and other personal problems, then the ability to learn during that time may not exist.
Right - sounds like you have more of a production support role vs. a data analysis workflow kind of task. Tacking on "exploratory" is helpful but I'm still concerned that you misuse the overall concept of analysis. It's decision-making task, which is practically the opposite of production support.
Hi tmpz22,

The slides are from decks that are publicly available on Slideshare.

The data (company name, year, funding stage, slide category...) is manually added by me with a lot of Google search.

The download includes 67 decks which corresponds to 1,210 slides.

It is true that in the download email, I also announce my next product, which is also free and also for entrepreneurs. So this seems fair to me - but happy to reconsider my position on that.

We might want new nucelar power plants for industrial centers. But what we certainly shouldn't be doing is using them as an excuse to propagate the idea of a centralized grid of power authorities distributing power nationally or globally.

Centralized grids are incredibly expensive, difficult to manage, and introduce single points of failure in the physical and information domains. We should be doing everything we can to decentralize our grids, promote distributed power generation and storage in urban and commercial installments, and focus on letting the municipal levels of government coordinate bulk storage appropriate to their needs.

Folks get so worked up about highly efficient new nuclear power plants that they forget about transit and storage, or argue that these aspects shouldn't be considered. Both ideas are deleterious to making a modern, resilient power infrastructure that's able to adapt to climate change, changes in the economic environment, and the increasing pace of modern technology in the space of power storage and delivery.

Until these goals can coexist with the call for a "nuclear new deal", we should view them for what they are: short-sighted and misguided attempts to make profit off a need without considering the actual long term goals that society has.

President Obama, was a fan of the show "Homeland", created by the makers of 24. The plot of homeland concerns a stereotypical arab terrorist organization infiltrating the US government and the cia's attempts to stop it. I hardly think it is fair to say that this is a "conservative" phenomenon. Members of both political parties seem have a fetish for watching federal law enforcement rough up stereotypical hollywood terrorists.
Wow, closed source shareware. I wonder if that's still a winning model.

Shareware was about leveraging the now defunct sneakernet via physical medium such as floppies and making it ok to copy software and give it to friends on the premise people who like it will feel morally obligated to pay a modest fee.

One can use this to express a large part of a deep ML model as a reversible function, thus drastically lowering memory requirements for backpropagation. The same technique, but applied by hand was recently used to speed up training for transformer language model: https://arxiv.org/abs/2001.04451

I think in the future we will see a trend of expressing most of DL model as reversible computation, with minimal irreversible module in the end and in the beginning.
Some knowledge we gain is negative. We've learned nuclear wasn't as promising as had been claimed.

More generally, in engineering most technologies must fail. That's because there are multiple technologies that can solve any given problem, and only one can come out on top. The number of niches < the number of different solutions.

If you think just wait, we'll learn more and nuclear wins, why doesn't that same argument apply to the technologies nuclear is competing against?

Indeed, it's a hard philosophical problem. On one hand we need to respect peoples privacy, but on the other FR would allow the police to act faster and catch dangerous people before they do more harm to society. I just hope they don't add a clause about dismissing evidence if FR was somehow part of the process, nothing is sadder than reading the "we have evidence of X doing Y, but the evidence was sent via improper channels so we can't prosecute"-stories.
Calling tear gas a “chemical weapon” is a rhetorical exaggeration that conjures up comparisons to actually lethal chemical weapons like nerve gas. The two are not the same. The 1925 Geneva protocol has exceptions for riot control agents to be used in various circumstances specifically because its wording is otherwise overly broad. Tear gas is a non lethal tool to bring crowds under control. The alternative is to let crime happen or to put both the police and criminals at greater risk.

In case of Seattle’s attempt at banning use of tear gas, the federal judge also didn’t say “the police might get significantly more violent”. Do you have a source on that, because it feels like editorializing. From https://crosscut.com/2020/07/judge-blocks-seattles-ban-tear-...

> The DOJ argued that implementing a ban on tear gas and other crowd control weapons, which the Seattle City Council passed in June, would result in “irreparable harm resulting from officer confusion and the inability to modulate force or de-escalate situations in which force may be needed.”

> "The issuance of this immediate change, without time for additional direction or training, is likely to result in officer confusion," he wrote.

Weird comment, the “unignorable” factor is the problem?
Not all generators in wind turbines require permanent magnets (which are made from rare earths). In fact most generators in wind turbines in the US do not have rare earths. But it should be said that generators with rare earths are more efficient.
Fast reactors could, in principle, blow up like atomic bombs (in the sense of having a prompt supercritical reaction with unmoderated neutrons.)
Perhaps that wasn't the best term for the point they're making. From the abstract:

"This paper presents a comprehensive techno-economic evaluation of two pathways: one reliant on wind, solar, and batteries, and another also including firm low-carbon options (nuclear, bioenergy, and natural gas with carbon capture and sequestration). Across all cases, the least-cost strategy to decarbonize electricity includes one or more firm low-carbon resources. Without these resources, electricity costs rise rapidly as CO2 limits approach zero. Batteries and demand flexibility do not substitute for firm resources."
We provide software that runs within very secure financial networks, and have some extreme constraints regarding what sorts of 3rd party code we can pull in. We are having to do a vendor swap on some document parsing code because one of our clients scanned a dependency and found it could be vulnerable in a context that it would never be exposed to in our application. These types of things make it really risky to go out and build your enterprise on top of someone else's idea of a good time.

Virtually everything we do is in-house on top of first party platform libraries - i.e. `System.`, `Microsoft.`, etc. We exclusively use SQLite for persistence in order to reduce attack surface. Our deliverables to our customers consist of a single binary package that is signed and traceable all the way through our devops tool chain, which is also developed in-house for this express purpose of tightly enforcing software release processes.

This approach is certainly slower than vendoring out everything to the 7 winds, but there are many other advantages. Every developer knows how everything works up and down the entire vertical since its all sitting inside one happy solution just an F12 away. Being able to see a true, enterprise-wide reference count above a particular property or method is like a drug to me at this point. We are definitely over the hill and reaping dividends for building our own stack. It did take 3-4 years though. Most organizations cannot afford to do what we did.

I doubt we'll every know that precisely. People are still trying to figure out how many died from flu in 1918. Here in the US the mortality rate is surely higher than .15 percent. The testing regimen is clearly not counting everyone who's been exposed; it is likely several times higher than the official count. But not yet anywhere close to half the population. And then there are places like Brazil and Mexico, where the disease is clearly rampant and the testing regimens are totally inadequate.

Gloss indeed, I think you'd be find just doing the straight line distance between stations. Possibly radius' if it's a long way. We just need the relative distance to/from places not that actual surface area.

If that's not good enough it'd be time to skip re-inventing the wheel and use the secondary port calculation.
Professionals exist for a reason. Whether software or investing, you are better off with a pro. All these anecdotes make my eyes roll.

>Please help me, what real value does an investment like this yield for the economy as a whole?

The argument usually goes like this: HFT firms provide liquidity for the market; they are usually the people on the other side of the trade when a retail investor buys stock/bonds/etc. So without the HFT firms, you wouldn't be able to trade at a good/fair price according to market conditions. Furthermore, if you buy stock from NASDAQ or NYSE or London stock exchange, you should get the same price. This idea that you should pay the same price for an asset regardless of where you buy it is enforced by HFT firms, as outlined in the article. Clearly, HFT firms need to get paid for this service, so retail investors typically pay the bid/ask spread.

What's wrong with 'pink slime' anyway? Isn't it an example of nose-to-tail eating and efficient use of the animals we can kill? Isn't that a good thing?
I agree.
By 'a waste', I didn't mean that it is not better, but I meant that it is a diminishing returns curve, and you will end up sacrificing a lot to achieve it (resolution and graphical quality, as computing is not free) and it doesn't feel that much better. Going from 60HZ to 120, or even 90HZ is very noticeable by everyone, even in normal 2D content. Past 120 it is like, eh, just a bit better.

Between 120HZ 4k, and 240HZ HD, I'd take the 120HZ 4k
Between 120HZ 4k, and 90HZ 4k but with fully Ray Casting, I'd take the 90HZ (unless it is a competitive FPS)

etc...
In my youth I bought one of those types of high end monitor second hand. Had 5 BNC inputs and required a resolution tweaking utility to change the sync polarity.

I spent hours tweaking convergence on the 9 million trim pots to get it just right. Best color gamut of any display I ever owned. Sadly the display physically broke something internal when I lost the included plastic screwdriver and tried using a metal one. The internal heads of the trim pots were apparently connected to the circuit.

The display was fixed to 1024x768x75Hz exactly (though you could squeeze in a bit more with modeline tweaking), but the colors were great.

This is ridiculous and obviously wrong. A chain reaction with moderated neutrons with water and graphite could not, even in principle, produce that much energy.
Maybe just a bit of a nudge? ;) ;) ;)
The issue with renewables isn't recycling, it's storage. Solar generates electricity in a sine wave. Half the day it's generating no electricity. Wind doesn't follow a sine wave, but has the potential to generate lower levels of power for long stretches of time. Wind is consistent on a yearly basis, but variable on a weekly basis.
Isn't there an obvious hidden random variable there? The only countries that are really actively building nuclear power are growing developing countries like India, so of course their emissions are increasing.

EDIT: So yes:

> "The study found that in countries with a high GDP per capita, nuclear electricity production does associate with a small drop in CO2 emissions."
And it takes a very long time. I’m not convinced at this point we have time to nuclear.

The WTF license is an antipattern really. All it does is push away anyone who has serious use cases for your work, because of the risk that nothing in that license will (likely) hold up in court. MIT carries basically the exact same provisions as WTF, so just use that.

I think “tyranny of the majority” refers generally to policies made with majority support, not necessarily by referendum.

To your specific question, though: often! In the US, state constitutional amendments and local ordinances are often decided by popular vote. For example, voters in New Jersey are currently choosing whether to legalize marijuana.
It could possibly be too late to start with new nuclear plants, although I'm not totally convinced.

If we had them now, nuclear plants would be vastly superior to coal plants for baseload, at least in terms of emissions.

The question is, if a nuclear plant takes 20-30 years from project start to being online, how will it compare with what's available then and over the design lifetime (50ish years). Of course, we can't know for sure, but if storage becomes good enough in the next 30 or so years, the lifetime economics of a nuclear plant get pretty bad.

That said, maybe the economic risk isn't as important as the emissions risk. If renewable + storage doesn't work, and we are still running coal plants in 30 years, that's probably worse than if renewable + storage works and ratepayers paid for an underutilized nuclear plant.
Thought it was interesting this focused on opinion or blog style stuff. Wonder if he ever does fiction or creative writing things.
It happens to all of us :)

In retrospect my comment might have read unintentionally sternly; I was just curious in case it was possible to track down where their policies were misrepresented originally.
It would be good to do a bit more work to justify that, then.

The NIA blog post doesn't even address the core point of the paper. It looks at a correlation of existing energy by US states, where our nuclear was largely built in the 1970s and 1980s.

In contrast, the academic paper looks at what has happened to countries , globally, that have tried to build nuclear since the 1990s.

And this is a crucial distinction, because the problem with nuclear is that economies have changed since the 1970s and we have new technologies with different costs.

So what if we look at what has happened to US states that, since 1990, have tried to build nuclear versus those that have tried to build renewables?

Nuclear has failed since the 1990s in the US, even with construction project with very strong community support and federal regulatory support from the NRC.

So when you ask the question that the paper asks: "does building new nuclear or renewables decrease carbon more with modern economies?" We see that the US recapitulates the same correlation that researchers found globally.

This huge bias of nuclear proponents, the inability to address the cost issue and very basic construction issues, is far more problematic for nuclear than a corrective analysis of what has happened to grids that have pursued different strategies.
I know people in that industry. I worked in an office and warehouse for that industry, but not in IT.

Some of the policies and stuff are the same across the industry due to restrictions in the government contracts. You will likely encounter a more bureaucratic and strict environment compared to other companies.

Pay and benefits are generally reasonable from what I've heard. I think they are falling behind on benefits compared to the PTO, student loan repayment, free food/perks, and paternal leave offered by others.

Great point. Adding onto this, an example of an auction is debt issuances. Also many exchanges use auctions (https://www.daytradetheworld.com/wiki/tse/#auction_mechanism...) during opens and closes. Essentially auction mechanisms mean that speed is not as important for participants.
Bike routes are currently heavily optimized already and sometimes I'm also a bit surprised about the good route quality ;) but actually this is only possible with the fantastic OpenStreetmap data. Still the most improvements are probably possible via data improvements in many areas. Still we will try to improve routes via "less turns" and more precise elevation data etc. For bike routing we only need to keep the balance between time, distance, simple route and beautiful route ;)

This is the kind of review I love to see. Not just for languages, everything. In my experience, reviews almost exclusively come while something is still novel to the reviewer, not battle tested, and worse, conflated with whatever situations the reviewer just happens to find themselves in at that period of time.

What a wonderful post to be able to read and not have to wonder how much of it will hold up given a little time.
> my concern is whether we can maintain a stable political environment for the decades/hundred years required to responsibly take care of nuclear.

Spot on. People often ignore the political problems of nuclear power:

- Centralization of control encourages corruption and the hiding of incidents

- Power stations make excellent targets in case of war. The bigger they are, the bigger the impact

- Nuclear power stations also cause social panic if hit, even if the damage is minimal

- The last two points apply to war but also to terrorism

If we want political stability (aka no wars) we need reasonably decentralized access to food, water, energy and information.
