I think you guys might like this personal research tool I launched about a month ago:

https://getpolarized.io/

It's actually designed for this use case around spaced repetition and it's designed to be a knowledge manager AROUND spaced repetition tools.

I should have cloud sync support in the next release (1-2 weeks) which will allow you to keep your data in the cloud and sync it between machines. Initially it will just support Firebase but I have plans to support other cloud providers via plugins.

I'd also like to support end to end encryption so that you don't have to worry about people reading your data.

There's a huge Hacker News about Polar here:

https://news.ycombinator.com/item?id=18219960

It also supports PDFs, text and area highlights, comments, flashcards and sync with Anki.

The initial response after our release has been amazing. The user base is really engaged with thousands of monthly active users and contributors.

Anyway. Take it for a spin. It's free and Open Source.
I think there is a better way.

1. Add package called `WebMarkupMin.AspNetCore2`.

2. Add and configure code in your `Startup.cs` like so.

services.AddWebMarkupMin(
options =>
{
options.AllowMinificationInDevelopmentEnvironment = true;
options.AllowCompressionInDevelopmentEnvironment = true;
options.DisablePoweredByHttpHeaders = true;
})
.AddHtmlMinification(
options =>
{
options.MinificationSettings.RemoveRedundantAttributes = true;
options.MinificationSettings.RemoveHttpProtocolFromAttributes = true;
options.MinificationSettings.RemoveHttpsProtocolFromAttributes = true;
// More options if you like so
})
.AddHttpCompression();

Not only will this minfy HTML output, but also apply a lot more optimisations based on your configuration.
I don’t know anything about the system in question but if it was mounted on a humvee it would have to be low power to avoid cooking people in the beam. Plus there will be so many reflections in an urban environment and the ranges are so short that you’d likely do better with a low power system. Maybe on the order of 5-25 watts.

That said, sinking say 10W of heat into your organs overnight is going to do serious damage.
I’ve been following these studies for awhile. The biggest red flag for me is that the effect is constrained to male rates. This is exactly the sort of result you expect to see when not sufficiently controlling for multiple statistical analyses (i.e., unintentional p-hacking). I suspect a Bayesian approach with an appropriate prior on sex-sensitive biological cancer effects would not yield statistically significant results.

Some other broad concerns are outlined here: https://theness.com/neurologicablog/index.php/that-rat-cellp...
Seemingly missing from the article, but present in the paper: the RF was at 900 MHz and 1900 MHz. Both frequencies are in the range in which water absorbs RF. Checks with "these scientists slow-cooked the mice with radio waves."

London also has a supply constrained by wealthy buyers of second and third homes for investment purposes. There are a lot of central residential areas without many people actually living in them and a lot of prime land taken up by spacious luxury residences.

If council tax were unfrozen and allowed to go up this effect would be mitigated and rents might actually go down.
Individual action doesn't matter. If you're only willing to spend 30% of your take home pay on rent, whereas your sociodemographic twin is willing to pay 50%, they'll outbid you.

Incidentally I currently spend 47% of my take-home on rent in London. At 32, buying a property is still out of my reach.

> so it's probably a standard topic around the world (I think it's used to understand Fourier analysis in more advanced courses).

These notes are contained in a chapter or two of any standard linear algebra textbook. This can serve as a background when studying analysis. Analysis starts with considering the real line first, then moves on to the metric spaces, then the normed spaces etc. That's when this stuff comes in handy. Typically, in linear algebra course one is introduced to norms and their properties; but analysis doesn't care about this stuff - it's just that LA ideas are used to further generalize analysis concepts. Fourier analysis (in mathematically rigorous sense) is introduced relatively late in ones analysis edjumacation. But the subject is important to engineers and physicists, so they get to be introduced to Fourier stuff as early as possible, but with much of the analytic rigor stripped.

Maybe you shouldn't store the file path but just the name, and a parent pointer. That brings you down to 8 bytes size + Parent pointer + a short string. Regarding the string you can go for offsets into a string pool (memory chunk containing zero terminated strings).

So I think 50 bytes per file is easy to accomplish if (name/parent/path) + size is all you want to cache. For speed-up, I would add another 4 or 8 bytes index to map each directory to its first child.

Ukraine bank offers 21% interest rate for doing 10,000 steps a day
>everyone's utility function is the same //

It really isn't. The cost of a $2000 for a poor person is huge, the cost for a richer person - whilst significant - is not debilitating. If you've 10% chance of getting caught then a rich person can afford it, getting caught really doesn't hurt so much.

That's why progressive justice systems use means tested fines for things like speeding.

I'm going to guess you're relatively wealthy, your analysis seems entirely wrong to me.

What you get with small fines is people will pay, even if they didn't deserve the fine, because of the cost of time/effort to challenge it.

If a company can save €100k for multiple years, the only downside being that if they're the 1:10000 that are caught they'll have a €20k fine, the financial analysis - morals aside - says don't pay, unless the €20k would sink you.

Oldest and Fatherless: The Terrible Secret of Tom Bombadil (2011)
Here we go again.

"The RFR exposure was intermittent, 10 minutes on and 10 minutes off, totaling about nine hours each day. RFR levels ranged from 1.5 to 6 watts per kilogram in rats, and 2.5 to 10 watts per kilogram in mice."

Even the lowest amount cited, 1.5w/kg, is far above what a human would receive standing directly in front of a cell tower transmitting antenna.

They basically cooked(because RF does cause heating) the mice alive for two years, and they developed cancer.

Interesting that the rats, who appear to have been exposed to lower amounts of RF, were the group identified as developing cancer.

Would be nice if articles like this actually linked to the study.
You can learn something new every day :)

I still wonder what the efficiency loss is on actually capturing the heat here so it is usable elsewhere while the building where it's generated stays cool. I guess most of the heat will be lost on the surface area of the building

I mean in district heating you use some closed, well isolated system. Though maybe they use water cooling and get a closed system with that.

What differences? I've noticed that selenium often fails because it can't find a certain element that is actually there. Specially if the window isn't focused, it gives false negatives a lot. I've switched test frameworks and had the same problems.
Edit: Obviously, I'm not GP, but here's my take on this.

> doesn't clean code always deliver a higher value as opposed to, say, messy code?

I'll agree with you there, but I'm under the impression that the phrase "clean code" is somewhat too ambiguous.

Coding style per se is very subjective anyway, so obsessing over it propably is not a good thing in most cases, yes. But if the "quick and dirty" approach also influences the architecture of what you're developing (i.e. it also affects other code) I'd very well argue that taking a stand against it is a good thing to do.

On a similar note: I find the notion of "technical debt" to be quite useful in a lot of ways: By taking the short path, you'll be forced to make up for it at a later date, be it through slower development, a lack of reliability or the necessity to clean up the "hacks". Where the metaphor breaks down (and seems to be contraproductive) is that it leads many business people to assume the debt (i.e. the negative impact) will be easy to quantify and can be treated like some other expense (and thus it often is ignored for far too long).

So, the first thing I ask whenever the "business side" asks for a quick and dirty fix for something (often mainly because of some production issue) is "When and how are we going to fix this properly? How will we deal with the downsides in the mean time?". This usually achieves my goal of making them think about the implications more -- I don't believe that's a very viable strategy in bigger companies, though.
A: Closing the deal.

The only exposure your bank has in terms of losing money is losing the costs associated with starting up the loan when you apply — there is a strong incentive to approve. The government owns the risk on performance.

This was a policy choice, because banks making subjective decisions usually looked a lot like redlining. Nobody would write a loan on a luxury condo in a rehabbed factory in the inner city because it’s a measurably higher risk. Bad schools, high crime, pollution, and risk of the condo board doing dumb things makes that a risk for the bank.
The language might seem harsh to you, but you'd understand it if you'd ever lived with or near such people.
It's also because they aspire to be part of the investment class.
Whenever this topic comes up, there are inevitably scores of commenters shitting on the ‘scientifically ignorant’ because cell phones emit non-ionizing radiation and therefore are not carcinogenic.

To me the important outcome of this study is to demonstrate that there is a spectrum (har har) of dosage and that there is now a fleck of evidence that non-ionizing radiation can cause cancer at higher levels.

The fact that humans are 50-100x the body mass of a rat is important obviously, but if most of the RF is being absorbed by the first few inches of brain matter by your ear maybe the effective difference isn’t so great.
Controversial spraying method aims to curb global warming
Take a look at the lumber market. The cost of building materials has been shooting up for the past 10 years. I believe houses are getting more expensive because returns on new builds come with much higher risk.

It’s cheaper to recycle the existing real estate market.
Briefly.
Absolutely. On top of the interest rates (and QE) we have:

1. Cities becoming much wealthier, and lower crime, resulting new generations moving there
2. New immigration wave to Western Countries. (UK esp had population relatively slow growing pop in the 50s, 60s, 70s)
3. A big demographic bulge of baby boomers getting ready for retirement saving as much as possible, looking for investments
4. Lots of money coming out of China looking for investments
5. Two huge stock market crashes leaving most people wary of stocks and seeing property as a safer investment
6. A combination of all factors pushing property even higher into bubble conditions.

Instead of showing who people are upfront, show their tweets without their identities attached, and let people follow based off of that. Anything else is just a diversity virtue signal.
Or that the rats, who were exposed to lower amounts of RF, were the ones that developed cancer attributable to the RF, but mice, who were exposed to higher levels of RF, did not show a statistically significant increase.

It doesn't work that way in practice. It's a weird argument and nobody would ever buy it as there is no obvious cognitive (and politically valid) path from climate change policy to healthcare policy. This is true for America, and Canada and Australia and I suspect every other country.

Also, your underlying assumption, that the American government either has no incentive or is uncaring with respect to keeping the American public health, is just wrong and probably betrays your ideology. Both parties, Dems and GOP, care about people.
I find your answer confusing. You initially clarify that you're talking about conscious decisions but your later claim is broad enough to include both conscious and unconscious bias.

I might agree that conscious racial bias is rare but I would find it harder to accept that unconscious racial bias is as uncommon as you claim. Does that sound reasonable?

Some napkin math:

It looks like mouse/rat weight varies widely, I'm going to be lazy and just pick 400g and from what I can tell, that also means about 400cm^2 body volume. Ultimately all that matters is the density though, which is unsurprisingly pretty close to water, close enough I'm not going to bother with it.

microwave power density = 1200W * 0.75 (efficiency estimate) / 22500cm^3 (interior volume) = 0.04W/cm^3

So in this experiment we have 1.5w to 10w * 0.4kg = 0.6W to 4W

In a 1200W microwave: 400cm^2 * 0.04W = 16W

In an 600W microwave: 8W (tho a 600W microwave is probably smaller so this may be low)

So a microwave would be 2-4 times more radiation than what they were exposed to in this experiment. Likely my power-to-rat-delivery estimate is a bit low for the microwave since I didn't take into account any sort of chamber resonance / reflection in the microwave enclosure, just it's baseline power density. Though, it would still get no where near dumping all it's power into something the size of a rat.

It seems to mostly boil down to the fact that they were able to work together with the Dart team to integrate the tooling, compiler and VM to provide a good debugging and hot reloading experience.

Kotlin/Native was not really ready at the time they started on Flutter.

But otherwise, I think Kotlin would be a much better fit, since it has fairly unique features to support building UI hierarchies[1] in code the way Flutter wants to do[2], which Dart lacks. They way this kind of code has to be written in Dart reminds me of old Java code, with callbacks using anonymous classes for lack of lambda functions.

If you ask, as you see the person's response - if their face isn't overcome with an expression of excitement, you could continue ... "or something interesting you've seen this year ... or any new place you've been ..." etc.

It's hard to come up with a good one-question strategy that would fit all. As you know more about the person it gets easier to ask fitting questions. For example if they have a child, that's a whole basket of good things to ask - let them be proud about the kid's first steps / first year in school / etc.

You're not an antenna, you're a reflector.

Just like you are a reflector for RFR at much greater power levels and much higher frequencies (light), yet only the highest energy ones(UV and above) cause cancer, and that is because they are of a sufficiently high energy that they are able to knock electrons away from atoms, turning them into ions(ionizing radiation).
