>asking the president of Ukraine to investigate a rival for political reasons goes against everything that Washington has been promoting in the developing world for decades: the rule of law and the independence of the judiciary.

Besides the obvious fact that "being a political rival of the president" is not, has never been, and should not become a reason to be above the law, the author clearly hasn't been paying attention to what the US government has actually been doing. Was the invasion of Iraq really about promoting democracy? Was Operation Timber Sycamore about promoting an independent judiciary in Syria? Is backing the coups in Turkey and Venezuela about promoting the rule of law? Obviously not. The US uses that language to subvert other countries for its own geopolitical interests.

The author appears oblivious of what his titular song actually refers to. If your revolution is promoted by the existing power structures then it's not a real revolution. The center left manufactures credibility by pretending to fight a revolution against the center right despite effectively sharing power with them.
I dream of a day when I can write UIs in Swift that work across Windows, Linux, and MacOS...

Can the news industry survive coronavirus?
Current scientist: I think the answer is easy. Take more risk. Science is by nature risky. We're trying to figure out things that we don't know. That results in a lot of failure (I definitely wouldn't use the Silicon Valley model of failure being a metric of success though).

One major change I would make from public money is publishing of results good or bad. There's this competition to get into top tier journals (which I don't think is bad or you can get rid of), but this is done at the cost of dumping good science just because it wasn't good enough for a top tier. Using impact as a metric is good but not great. The mark of a good scientist is their work and their passion, not where they publish. While there's a correlation, there's also Goodhart. If this is the only metric that we really concentrate on, then it will lead to slower science. We all know that we learn much more from failure than success. We all know that most of science is banging your head on the table for weeks out of frustration. But that's also not common knowledge.

So I'd say that those funding science need to be more risky and those in science need to be more open about their failures and be realistic in their discussion of science.

The Revolution of Remote Work. Part 2: The Present
> Rust's model definitely maps much more easily to a kernel, since the dominant pattern will be to drain a buffer, poke a device, and then wait for an interrupt to happen (the interrupt handler calling the wake function).

What is nice about Rusts model is that it prevents the continuation from running inline the event handler which signaled the completion. That avoids a ton of reentrancy issues and questions around "where does my code actually run"? That indeed makes it also interesting to use for interrupt handlers, since it is guaranteed that the code which waits for the interrupt to happen runs purely in the executors thread and will not accidentally take over the interrupt handler.

Fair enough, but I'm having trouble understanding the point of the abstraction. Open-UI sounds like it wants to be an overarching standard that all design systems should work to. So they can inter-operate. Which in my opinion is a flawed idea.
Here are some serious outstanding problems in software:

* Considering how fast modern computers are, software is so damn slow.

* Software frequently stops working. When it does, the process to diagnose the bug and fix it conclusively is not a straightforward one.

* Software is poorly understood. Most developers today work with other people’s abstractions. It’s rare to find a software system that someone can describe the inner workings of end to end.

* Software is excessively complex. To understand a codebase, you might have to crawl through ten layers of dependencies, imports, and scaffolding before finding code that actually does anything.

These are just some obvious ones off the top of my head. Does following the advice on this list make me any better at tackling any of these problems?

Could someone conceivably do none of the things on this list, and still be a very skilled developer who makes strong strides toward solving these problems?

I wasn’t sure if you were aware of this already or not but capital gains are not taxed at a marginal tax rate plus anything, they are taxed at 0%, 15% or 20%.

However, it’s worth noting that in terms of market volume, most entities that buy shares (like pension funds) don’t pay any taxes on their dividends or stock sales, so your scheme won’t make dividends attractive to these entities and indeed would likely raise the price, making them even less interesting to those entities.

This is why pension funds don’t buy (many) munis or TIPS etc. - they gain nothing from the tax advantages.
If people in those places have Visa/Mastercard credit cards, I'd expect to be able to charge them in Stripe just like any other card. Sure, https://stripe.com/global doesn't list Pakistan, but that's the list of countries your company is allowed to be based in -- your customers can be anywhere in the world.

If people in those places don't have credit cards, I'd wait for Stripe to add whatever payment method they do use. (They've already added systems like Alipay and Klarna that are mainly used outside the US.) In the meantime, they can email me and we'll work out if they can mail me a check or use Western Union, or maybe I'll just give them an extended free trial or something. There are probably not so many people in the world who (a) don't have credit cards and (b) are interested in my software-as-a-service that I wouldn't be able to manually help them on a case-by-case basis.

I agree; but think of it this way: if lending libraries hadn't been a thing for a long time when ebooks came along, they wouldn't even be allowed to do CDL. They'd have said "no transfer of ownership whatsoever", just like iTunes does.

It works mainly because the audience was 'educated', and part of this process lets the power instill its 'values' into youngsters' brains.

In most of the Western World and a not-so-distant past some Christian Church was in charge of this, and we had Crusades, clerics baptizing guns...

The main cause may be the will to 'enhance' the populace by using education in order to inoculate values. We may escape by only teaching fundamentals (either politically neutral or boosting a critical mindset). Letting a central power mix proper education with its messages leads to total war.

What is your take on the need for time-travel queries for versioned, mutable data? Versioning immutable data items is not enough if you have structured data that is updated. Every time you update a data item, you store a full copy - not a diff of the actual data. You are not able to make "time-travel queries" - give me the data that was generated in this time-range, for example.

For example, if you have a Feature Store for ML, and you want to say "Give me train/test data for these features for the years 2012-2020". This isn't possible with versioned immutable data items. Also, if you don't store the diffs in data - if you store immutable copies, you get explosive growth in data volumes. There are 2 (maybe 3) frameworks that allow such time-travel queries i am aware of: Apache Hudi (Uber) and Databricks Delta. (Apache Iceberg by Netflix will have support soon.)

It's also beyond much of the US to implement 80-90 degree temperatures that dramatically limit the ability for SARS-Cov-2 to spread as in Singapore.

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3551767

See: Hawaii, Texas, Nevada, New Mexico, Arizona, much of California and a lot of the warmer south. Which are all seeing between extremely low and low localized per capita transmission levels and hospitalizations, despite the very lagged (and overall mediocre) US response.

The Las Vegas metro area will be 80 degrees on Wednesday. Take a look at their deaths and hospitalizations (despite having millions of people). With their international traffic, vast number of casinos and casino workers, slow speed at which they shut it all down and the initially lagged testing rates, they should be absolutely buried in Covid cases and deaths. They're anything but and they're seeing no big surge in cases.

These temps are the reason why the experts are hopefully anticipating the infection rates to rapidly bend down in the coming weeks, and perhaps peak in May or June. Even very informed people like Bill Gates have spoken publicly about being hopeful about this (see his recent Ted Connects talk, it's about an hour long and almost exclusively about this situation). It's the seasonal temperature increase (and to an extent humidity) factor.

edit: I understand why some people don't like these facts, I understand the emotional response. The numbers don't lie: hotter climates in the US are not seeing the surge in cases, they're not seeing the same hospitalization rates and as a consequence they're not seeing the deaths as in the other climates like NY, NJ, MA, IL, CT, MI.

Check out all the cities in Texas (huge population), their metro areas, and look at the per capita rates of infection, hospitalization and death. Then compare.

This isn't going to happen outside of rare cases. Lots of companies are not just laying people off, they've folded entirely. People I personally know work for companies that have closed shop entirely in recent weeks. Those jobs are gone.

Of course, plenty of companies will not bankrupt, but of those that don't, they aren't going to be expanding their payroll anytime soon after the stock market just took an absolute pummeling and removed years of economic gain in days.

The market is currently being propped up by the federal reserve providing unlimited quantitative easing at the cost of inflation, not a long term solution. Even if we gave everyone a cure and vaccine tomorrow, we are on shaky ground because of what the fed has been doing, for better or worse, and will be in a recession for years.

> As a scientist the first test is intuition.

I have been wrong so many times. Moreover, I'm very good to point the right idea but like 50% of the times I get the conclusion in the wrong direction. Luckily my coworkers take a look. (And none of the decisions involve human or animal lives.)

> The second test is having people getting better with treatment.

The dead rate is something between 0.2% and 20%. It depends on your age, your health, and how wide is the test network. It's a 100 fold (and perhaps more). So whatever you do, most of the patients will get better. And without a baseline it is very difficult to compare.

For example, they ask the people if they want to participate. This is a filter that exclude the people that is very ill. What is the death rate in the subgroup of persons that are capable of signing a form?

> You try something. It seems to work.

How are you sure that it is working if you don't have data to compare? The "control group" was in another hospital. Does the patients in the other hospital have the same median income level? (Being poor is corelated to a lot of health problems.) Can all the patients in the other hospital sign a form? Is the other hospital nearby a university and it get a lot of young patients or it is nearby a geriatric and it get a lot of old patients?

> Now it's time to act. Not pull over waiting for some authority to decide for yourself.

But we don't know if this treatment is good or bad. Someone posted a link in another thread to a list of 20 home remedies and supplements that may be helpful. Which one should we apply? Can we use all of them together? Which are the side effects? They are not very well tested, so some of them may be harmful.

Note that in this study, one of the persons treated with the combination of drugs died, but none in the "control group" died. What is the conclusion? Is this combination of drugs safe? (Note: This is clearly a fluke.)

> The list of publications is here to show that this available treatment doesn't come from a magical hat.

Cross out the first study because it is not reliable. Try to read the second one more carefully, perhaps it has some surprises.
> I think you should consider listening more to your supervisor. I know nothing about your field, but I've seen a lot of PhDs go off the rails because they chased after something they thought was a great idea only to find it was a problem no one really cared about.

Unfortunately only so much can be communicated in an online comment. I tried going into detail, but I'll leave it at this: I do listen to my advisor, but I disagree with him about how science is best done.

> The incremental "find an open problem mentioned elsewhere and work on that for a while" isn't a bad way to start a PhD career. You learn a bunch about the field doing that.

Reading your paragraph makes me think my point wasn't communicated clearly. I'm not arguing against working on open problems. I'm saying to make sure that the problem is actually open, and don't start doing expensive things like experiments without having a good idea of what you're doing. Given the existence of a large amount of archival literature, your great idea is likely to have been done already. There is value in reproducing previous experiments, but people should do new research too.

> This seems an odd thing to complain about. Surely a PhD is all about peer review, and should be so. Peer review means people who know about the topic have reviewed it - how else should a PhD be done?

For what it's worth I don't believe peer review as currently practiced in journals provides much value. The reviews tend to be superficial at best, and are provided far too late in the research process to have a strong influence on it. In my experience the reviews mostly help to make the paper more clear, and not because the reviewers give good suggestions on writing themselves, rather, because the reviewers seem confused about things I thought were written clearly.

However, my advisor is definitely a strong believer in peer review as currently practiced. I mis-characterized him before. For him it's less "publishing in journals is the right thing to do" and more "publishing in journals provides a strong check on the work".

In my view, the most important thing someone can do to improve their research is to be deeply critical of it. Unfortunately few people are critical of their own work. Getting feedback from others is valuable, but I believe that the best way to do so at present is to actively solicit it yourself, which is what I've been doing. Peer review in a journal should be the last step, not the only step aside from one's supervisor looking over the work.

Also, I removed a paragraph about how I strongly dislike the current academic publishers. That's a major factor here as well. My field does not have good open access options at present. I'd really prefer to wait a few years as I think the landscape could change dramatically.

>Are you saying that if you own shares of company A, the value of those shares is extracted from the company's bank account?

Like the sibling comment said, thats how stocks are supposed to work. The entire reason stocks have value is because you were entitled to a dividend. So that $75 would be shared among the people who own the stock.

Now if the stock entitles you to a dividend of $5/year of the company's profits, you then might say that the company's stock is with $25 (just an example). If you think the company may become more profitable, and start paying $6, you may decide the stock is worth $26, and the inverse is true as well. Transferring that ownership of the stock is taxed, naturally.

Now we now live in a world where the largest companies don't pay a dividend, and I'm not sure how much "potential dividend revenue" factors into company valuation, but, as I understand it, this is the "backbone" of how stocks work.

>and the much more reasonable thing to do is have the company pay me a salary out of its profits. Which is another, separate, taxed, transaction.

This is taxed separately however. There is no "double-tax" here as payments to employees aren't considered the company's profit. When the company pays its employees, it's taxed once (payroll tax). When the company pays it's owners it's taxed twice (Corporate tax, then dividend tax).
