This article from today is somewhat obsolete. MiFID II regulations require absolute accuracy of either 100 microseconds or 1 millisecond depending on certain conditions, and reporting in microseconds. I don't know why they went with microseconds when nanoseconds would have been technically just as practical and far more future-proof.

Nuclear power isn't very "dispatchable", it takes long times to be turned on vs off. But it might be useful for seasonal use in the winter when there is less sun.
This looks great, but my first thought was, "what happens when all these new cyclists experience their first winter on a bike?"

Not saying that it _should_ cause them to reconsider, just that it might, and we won't really know until we see what happens in December-January.
The vroom R package is likely the fastest R package in read speed, not the ones used in this article. vroom was 13.1x faster than R's fread/data.table based on the read performance benchmark in https://cran.r-project.org/web/packages/vroom/vignettes/benc... so may be similar or faster in read speed vs julia.

You are right that Schwab makes a pretty good profit from it. The way they do that is by lending "your" money to their margin customers and charging those people 7% or more while paying you pennies.

In a "margin" brokerage account, "your" money is merely a debt obligation of Schwab.

TD Ameritrade (and now I think Schwab) will sweep cash from your brokerage account into a real, genuine, bank account. But the interest rate is still almost nothing.

The idea of a “uniform” has been lost on the police and sheriff departments of the communities I live around. Two officers in the patrol car together will wear completely different outfits. One will be in the traditional blue uniform, wearing a tactical vest with plates on the outside, while the other will be dressed half plainclothes. Khakis with a polo embroidered with a badge and a ball cap.

The brewery where I used to brew was better at coordinating the daily uniform.
There are several problems with trading at 1 second intervals (or any other fixed interval):

A) What do you do when bids and asks do not match up? Who's orders get filled and who's do not? There are several possible answers to this problem, but not are satisfactory.

B) You do not eliminate the advantage of speed because everyone is still incentivized to put in their orders at the last possible moment before the end of the interval.

The world is continuous, not discrete. Therefore, like it or not, trading must be continuous and not discrete.

Yes, this. As the old Soviet saying went, "show me the man and I'll show you the crime."

When you place the burden on the people and not the state - often through "common sense laws/regulation" - you inherently enable subjective and arbitrary enforcement of the law.

This unfortunate trend not only creates and enables petty tyrants, but disproportionally afflicts the most vulnerable in society and politically disfavored minorities.

Target date retirement funds aren't new? And they include bonds, so of course you're not going to beat the market with them.

Most target date funds (Vanguard, Fidelity's Zero funds, Schwab's Target Date Index) use passive index funds and are exceedingly cheap and have excellent performance. Schwab's have a net ER of just 0.08%, the lowest in the industry, beating Vanguard by 7 basis points.

There are some ridiculously complicated and overpriced TDFs (T. Rowe Price comes to mind) out there, of course. Knowing what you buy is important.

The reason the NASDAQ 100 is beating the S&P is because of FAANG stocks, and the trend has mostly been the last decade or so. Meanwhile, the total market index is pretty much on par with the S&P since 1992 [1].

Well the currently deployed, old nuclear plants certainly aren't as safe as the new, unbuilt ones the nuclear proponents always like to showcase. Even if you decide towards using nuclear in the future, you should build new reactors from scratch using those new safer designs.

4,000 is not a conservative estimate.

It is based on the UNSCEAR report, which I consider to be the authoritative source. The following WHO write-up provides a full breakdown by category. [1] The 30-60K number is scaremongering. The UNSCEAR report is about 600 pages and took 20 years to compile, and included 8 intergovernmental organizations and all the local affected governments.

"Alongside radiation-induced deaths and diseases, the report labels the mental health impact of Chernobyl as 'the largest public health problem created by the accident' and partially attributes this damaging psychological impact to a lack of accurate information." [1] This was a material problem, as many people killed themselves believing they were "contaminated" when, in reality, that were just fine.

As the link covers (both yours and mine), the primary cancers attributable to Chernobyl are thyroid cancer, due to radioactive iodine. Thyroid cancers have a 99% survival rate. This is curiously omitted in your link. Thankfully, I-131 has a half-life of just 8 days and is long, long gone.

Major incidents should not, in my opinion, dominate the discourse. After all, we're fine with hydro power when the Bangqiao Dam incident killed up to 200,000 people in one fell swoop. A single dam failure could easily cause drastically more harm than a nuclear incident.

> "Can you imagine it? A European catastrophe."

26% of all power generated in Europe comes from nuclear today. Luckily, they have learned from their mistakes and improved processes and safety measures.

[edit] The discrepancy in your link I suspect comes from this: "Excess cancer deaths can be estimated from published collective doses."

Further, I suspect the actual extent of future deaths will be lower than even UNSCEAR. They support the "linear no-threshold dose response" model, where any amount of increased radiation exposure leads to a proportional increase cancer deaths. However, this model is being challenged, as experimental evidence shows this is not consistent with biological and experimental data [2].

There is also geothermal energy (Alaska, West Coast, Rockies; I assume we are talking solely the USA here) and hydroelectric power (Alaska, West Coast, South East, and more).

But we often don’t talk about the energy wasted in bad location of industries. E.g. growing water demanding crops in the Mid-West or South East instead of California where water is scarce, or energy intensive industries in Alaska (where energy is plentiful) instead of Texas where it is scarce.

Another thing not mentioned is wasted energy because of lacking infrastructure. This also applies to the rest of the world. A good example is not building high speed rail connection between high travel areas, so people use polluting air travel instead, another is lack of waste management facilities so garbage is left to rot instead of reused or recycled lowering demand for making the same thing again in a far away facility.
The amount of money being made in the arms race has gone down hugely over time due to computerization. Spreads are 1/10th of what they used to be (or smaller in many cases). There's really no need to fight this fight with taxes. The war has already been won.
Yep - I get the "it just works" argument.

But just remember folks, Windows 10 telemetry is basically Microsoft-sanctioned adware/spyware right on your computer. I've done a "base setup" of W10 sniffing traffic from a clean/fully patched install and it talks to everyone. The only way I've been able to mitigate this is running LTSB/LTSC versions along side of reputable "disable telemetry" software pulled from GH. It's gross.

Although I admit to fighting with my Debian installations from time to time, at least they respect my privacy.

I think anyone who is a step up from a casual gamer would recognize the difference between 60hz and 120hz if they were somewhat familiar with a game. Especially games that required tracking your opponent with a mouse, such as aiming a hit scan weapon like a lightning gun where your goal is to keep a continuous beam on them while both of you move unpredictably.

It was especially apparent in Quake 3 back in the day. If you didn't run at 125 fps with a 120hz refresh rate you were at a disadvantage at competitive levels. Not even world class competitive, but enough to be good enough to play in tournaments with thousands of dollars in prizes.

If you ever want to see hardcore technical analysis of hardware from a gamer's POV, try reading forum threads from the early 2000s when ball mice started to transition to laser and optical mice. Or using after market Teflon pads on your mouse feet to get more consistent friction.

Fortunately most of these things were only a few bucks. Most competitive gamers in Quake would also use config settings that reduced the graphics quality[0] of the game to maximize visibility and get consistent frame rates.

For 1), it is simple, but not trivial to parallelize csv parsing correctly, hence the yesterday’s post.

Otherwise, agree on 2 and 3. Object wrapping, number decoding can be slow on the whole “file to dataframe object” path, but trivially parallelizable.

> Reactors from civilian plants don’t blow up like atomic bombs...

No they don't, but they do blow up like industrial hydrogen gas explosions. Loss of coolant accidents are unforgiving in boiling water reactors and quickly fail catastrophically (in the engineering sense).

> the 1950s design CANDU reactor is small enough to be considered “modular”

Ummm, no. I stood in front of reactor #4 at Darlington just before it went into production. I think this was the last CANDU reactor to go into service in Canada. The scale of the reactor, the turbine hall, and the containment building are incomparable to anything else man-made that I've experienced.

The large size compared to equivalent boiling water reactors accounts for the CANDU's primary failing: it costs too much. Especially in the age of fracking, nuclear is uncompetitive cost wise compared to natural gas.

The supporters of nuclear energy and The Green New Deal both rely on a working assumption that the cost of CO2 emissions is the only important factor moving forward. Geographic and geopolitical considerations may play a significant role in continental Europe, Japan, and China but I have yet to hear a reasonable non-ideological argument against a natural gas centric strategy in North America.
Yeah, you kind of fell right into the trap I was talking about. Your approach either requires being able to memory map the CSV data or storing the CSV data in memory. And to be honest, it's not clear to me that your approach would end up being faster anyway. There's a lot of overhead buried in there, and it sounds like it's at least two passes over the data in common cases. And in cases where there are line breaks in the data, your approach will perform very poorly I think.
Engineering definitely scales sub-linearly to revenue (unless you're a body shop), but it's definitely always still above a constant. Large tech companies would be crazy to keep their engineering teams artificially low, because when you're making billions in revenue the added headcount ends up paying for itself even if it's only capturing that last 1% of possible product efficiency gains. Like, Google Search could be nearly as good as it is now with 1/20th the engineers -- but that last bit of improvement is still absolutely worth having the much bigger team.
B) you don’t advertise orders until the end of the second; for all ordering questions within your algorithm, you assume they have arrived at a certain random order; given two of the above, you resolve all of the orders at that end of the second too
In a similar vein perhaps people have seen a statistic going around about a "0.13% death rate".

The origin of the 0.13% death rate statistic is as follows: On Monday Oct 05 the WHO announced there were 750 million cases of Covid worldwide (see tons of news sources). According to the official WHO tracker there have been 1 million deaths.

1 million divided by 750 million is 0.00133333 or 0.13% IFR.

I suppose this is not limited to the internet marketing genre, but I've found from my own experience, this is common.

Small anecdote: I was once asked to review an ebook in the internet marketing space based on some things I was doing at the time. The "author" had created an ebook that consisted of clipart, default Microsoft Word formatting, and egregious spacing to pump up the page count. The "author" was furious when my review was neutral rather than glowing.

This is another in the "Now that we have computers with gazillions of bits of RAM and many cores and gazillions of cycles, what conventional wisdom is no longer wise?" series :-).

I suggested to a client that they use Sqlite3 for their company database rather than a disk based database. And they looked at me shocked, as if I had spoken heresy. I pointed out how many records they could store on a 64GB machine and that is a small data center class machine and it sort of boggled their mind. Add read-only copies, shared from a NAS device gave them perfect scalability in terms of queries per second (their sales folks had their own database that they were updating). It was fun to watch their expression go from horror to wonder to excitement when they finally implemented it.

Nuclear reactors per se can be made pretty small, e.g. research reactors typically have a maximum (steady state) power output of a few hundred kW (roughly a car engine). OTOH the minimum economic size is probably somewhat larger.

I would imagine there's similar issues as with nuclear power plants on land, that is, to get the best return on the invested capital you want to run them with as high capacity factor as possible. So some short-range ship that spends a large fraction of its time in port is probably a poor match, whereas a trans-oceanic liner with quick turnarounds, like a container ship, could make for a good fit.

Nowadays there's "New Panamax", after a new set of locks opened in 2016 enabling (much) bigger ships.
Is there a source for this?

I’ve been using it for months and it’s seriously good. It’s really a shame that one person can write something like this and yet Slack “doesn’t have the resources” to make their experience better on native platforms.
And to address the other half of your question, the lower costs for solar and wind take into account the lifetime of the generation, and it's usually measured by the levelized cost of energy (LCOE) which is roughly the lifetime cost divided by the lifetime energy output. This does not take into account the value of the time that energy is delivered, so LCOE is not directly comparable for renewables and dispatchable generation like natural gas (though a huge percentage of the new solar and wind deploys for the next 5 years are adding storage to convert them into dispatchable resources.)

As for the disposal costs, that's a fairy trivial problem. Solar panel recycling has not really started because there's not many dead panels to recycle; lifetimes are tending to be longer than expected. However as there is a larger source of retired solar panels, those attempting to recycle them will get a better feel for the costs of construction of new panels from raw materials versus recycled magerials.

It's not that Windows has backward compatibility solved better than anyone. It's that they don't remove the old stuff. They only removed Win16 in the 64-bit versions of Windows so it was around for 20 years. Perhaps they will leave Win32 in until they come out with Win128.

I find teflon tape to be not great not terible for threaded water fittings. Sometimes I find it is just too thin and needs to be wound too many times.
In these cases I find that a bit of caulk covered afterwards in tape works best.
There is also a product like a thread covered in teflon (looks kinda like dental floss) but I never tried it because it was too expensive. Maybe as a professional it saves time.

Also I found that the direction you wind the tape matters. It is easier if the female/receptacle/socket part that needs to be screwed does not go against the end of the tape but in the same direction.
A nice read, and I'm very happy to see the author progress from foster homes to the military to academia and finally to the brink of a PhD.

The pattern I don't like is the one where people load JS like jQuery from a CDN with a local fallback if that doesn't work:

- realistically, nobody is going to be testing if the fallback functionality works as the site grows so you're going to get weird breakages if the fallback misbehaves (e.g. your local file is a different version).

- big CDNs go down so rarely it's not worth thinking about (and if it is serve it from your own site)

- it's easy nowadays to put your whole site behind a CDN so there's little point (the article debunks the caching advantages)

I think people are just copy/pasting snippets that do this from somewhere without thinking.
> In order to do it, they bored through mountains in Pennsylvania in order to make the path of the wire as straight as possible, reducing the distance information had to travel. In total, the project cost \$300 million. The result? They can send information in 13.3 milliseconds round trip, 3 milliseconds faster than the competition at the time. So we can see that a 3 millisecond edge is worth at least \$300 million.

I understand the motivation and rationale and that my take here is subjective, but I take a pause at how sad it is that we're literally boring holes through our natural mountains in order to flip bits 3ms faster in the name of high frequency trading.
