> I never used LinkedIn... hadn't even updated my profile in the 9 months since I left my last software engineering job.

So you use LinkedIn only passively, never do anything on the platform and then write a rant on how it provides you no value? Maybe actually _try_ to use the strengths of LinkedIn before you dismiss it?
But what if the urge to seek CBT is itself a part of our ex-post-facto narration?
> Can you please provide an example of the energy mix of a 100% renewable grid? I don't even know what it looks like in theory.

It's not hard to imagine, if you allow yourself to think about it (which I suggest you do so you can cease embarrassing yourself here.)

For Germany, one can just look at simple model outputs, using real weather data. The site I often point to, https://model.energy/ allows you to find optimum solutions to the problem of producing a steady amount of power. This ignores seasonality of demand, but it good for addressing the "but nuclear" fanboys, since nuclear reactors produce near steady output. The assumed 2030 cost for H2 electrolysers there is already well above current costs; decline has been more rapid than expected.

If you go to that site and ask for solutions for Germany, you get a mix that includes wind, solar, batteries, and hydrogen (about 6 hours of battery storage, and about a week of hydrogen storage.)

This solution does NOT include thermal storage, which would be very large for many applications, as it is extremely cheap. In particular, underground storage of low grade heat would likely be used for district heating.

> Because there isn't one and not without trying. Germany is a perfect example. A very rich, progressive country with a massive budget surplus .. and yet they aren't doing it

They aren't doing it because the CO2 cost needed to make it happen isn't in place yet. An argument very similar to yours was made about them getting off coal. "Look at Germany, still burning all that coal." Yet when the European CO2 market was tweaked to increase the cost of CO2 credits, coal use in Germany began to rapidly decline. It wasn't high because coal is essential and irreplaceable, it was high because the market signals made it high. Change those signals and other solutions are adopted.

You are confusing what is currently cheapest with what is physically possible or practical. These are not the same thing.

> Are you sure you're not the Flat Earther?

Yes, absolutely. You're the one engaging in shoddy and illogical arguments, the "it hasn't happened yet therefore it can't happen", the one ignoring the repeated refutations of your clear logical errors and misconceptions.

Depends on what you want to filter. I used to have unsafe water from my well, and only reverse osmosis could make it safe. However safety isn't the only reason to filter water. If it is safe to drink but looks dirty a cheaper partical filter removes mud. If it is safe but tastes bad an activated charcoal filter will often be a cheap cure. If it is hard a water softener will fix that, but you want to drink the hard water instead of the softened water (though sodium content doesn't seem to be as much of a worry as it was 30 years ago. I'm note sure that it is science changing or not). I've also seen Iron filters.

Depending on the problem you need a different filter. Fridge filters only solve the simple problems where the water isn't too bad in the first place.
I figure the reasoning is this:

soon everyone will do this, by the time someone who had this happen to them and got mad gets around to buying another fridge it will be industry wide procedure - therefore they will accept it (or do without a fridge) and then they will buy our product based on some other calculation than if it has the mal-feature that every other fridge will have.
Where did they say "selfish"?

This wouldn't be a problem if it was a case of choosing between A) paying $15 to the restaurant or B) $15 to the restaurant plus $5 in delivery.

However, in reality you're choosing between paying A) $15 directly to the restaurant or B) $12 to the restaurant and $8 for delivery.

Hopefully the added volume of orders makes up for the $3 (made up numbers by the way), but I'm not so sure.

Google will report how busy some business are on an hour by hour basis, I assume based on anonymous phone locations collected. If google covers the business you want to go to that would solve the coordination problem.

I'm not sure how to make google show this information. Usually I can just look up "[business] hours" and it will give me the plot, it might not be showing that information right now due to low activity because of the lock down.
In a related area, American companies produce on-patent drugs in owned European factories by process-copy-identical methods. They purposely do NOT go through the paperwork of obtaining FDA approval for these processes and factories, though identical. (Of course rigorous European approvals are obtained.) NOW, it becomes illegal to import the European versions into the U.S. and Customs cooperates by random seizure of small shipments, thereby harassing American, mostly older citizens on limited budgets, directly.
It looks like their comment added the same value, posing several questions about the value of comments about low value posts. Shouldn't you praise it?

Yeah, someone who doesn't use LinkedIn "closed" it. Who gives a shit. Well, a lot of people do because they desperately need the bottom feeders fretting over their LinkedIn because it helpfully debases everyone.

Anyone who relies upon LinkedIn for anything (rolodex, word of mouth, contacts) has failed in life and career.

This comment is for the edification of the good people use use showdead.
It's not happening yet because the cost of CO2 is not high enough yet to make it competitive. Having said that, Germany is putting a lot of money into hydrogen, and this is driving down the cost of electrolysers, the same way Germany drove down the cost of PV a decade ago.
Depending on the outcome you desire, this could be a perfectly designed activity.
We’re starting to see some big cracks in the armor of democracy (polarization and entropy) and capitalism (inequality) so perhaps iterations or complete substitution of these pillars of modern life should be expected sooner than later
Has anyone here used Cortana for anything? I really hate to see it using CPU/RAM.
Its not an argument on the scale of the operation but rather if alternatives exist. I am merely stating that burning down a library is not less of a loss if an alternative exists, especially seeing that you'd need to find the new archive and get awareness out about its new location.
> Until you can demonstrate that isn't the case then using crime statistics as an excuse for police actions will be questionable at best

What else can be used other than statistics? Is there some other common frame of reference out there?
I made exactly the same mistake initially :)
I see UDP as superior in general, and don't see a good reason to use SCTP at this point for any real use case.

IMO, it's a "good thing" for applications (or types of application) to have control over the Transmission Layer since the characteristics that each type of application might desire is different. Want your app to use raw UDP sockets? Easy. Want to use QUIC? Use a QUIC library. HTTP/3? Use and HTTP/3 library.

If it all used SCTP, you are locked in to its feature set and are likely to end up with new problems similar to what we see with TCP.

I could possibly UDP/QUIC taking over TCP in a long, long while, but SCTP is not likely to ever be usefully supported because there isn't a compelling reason to do it.
This is already happening, see these rules for foreign travel published by the Czech ministry of health:

There is a map with green, orange and green countries.

UK and Sweden are red, most of western Europe orange.

For green countries, Czech citizens can go there and back without the need to present negative tests results and enter quarantine. Same thing for residents and nationals of those countries.

For orange countries, Czech citizens can go there and back without the need to present negative tests results and enter quarantine. Residents and nationals of those countries are banned from entering Czech Republic.

For red countries, Czech citizens can go there but need to present negative tests results and enter quarantine. Residents and nationals of those countries are banned from entering Czech Republic.

Also a big assumption here is that black people dont plead guilty to crimes they haven't committed at a higher rate than the rest of the population.

Ive seen a lot of evidence of black people not being able to fully prove their innocence and taking a plea deal because they would rather spend 6 months in jail over fighting, with the aid of an incompetent public defender, to avoid a 10 year sentence.

With all the corruption caught on officer body cameras in just the last 5 years (planting drugs, killing innocent people, unnecessary excessive force, death penalty/life sentence convictions overturned, prosecutors caught hiding evidence of innocence, etc)... It is safe to assume that this level of corruption (which is in many cases protected by both qualified immunity and prosecutorial immunity) has been going on for decades, heavily skewing black crime stats with false entries.
Maybe the linked article has been updated since you posted, but this is not true of the current article.

Yes, they were distributing a modified ISO and it probably should/could have been taken down on straight copyright grounds. But the article is about the fact that rather than concentrating on this clear violation, the DMCA complaint specifically calls out the modifications as infringing because "the link provides a work around technical restrictions of the software". This distinction is directly addressed in the paragraph that starts "At first view, some may conclude that Ninjutsu OS amounts to a heavily modified yet pirated version of Windows 10."
" nothing to do with the cost of production."

The cost of production is generally not a meaningful measure of underlying costs. Although sometimes it is.

Drugs are a little bit like software 'making is hard' while 'copying is cheap'.

Of course, most software doesn't save lives.
I've actually done some side by side tests with stains using conditioner vs not. I wouldn't call it necessary by any means. Depends on the stain and the wood but sometimes I did feel the result was noticeably better, sometimes I couldn't tell the difference.
> Obviously nobody expects the police not to shoot back when fired upon.

When police creates situation in which the other person has no reason to think they are police, where that person can reasonably think it would be legal to shoot, yes I do. That whole situation was created by police and they had time to prepare. So yes, I expect them not to shoot randomly.

It is not reasonable to expect less from police then we expect from civilians.
Performance is a secondary concern. SourceHut already has the best performance in the industry, built on Python:

https://forgeperf.org

But I think it could be even better, and this work will help. It will make it easier to write performant code without explicitly hand-optimizing everything.

There are more important reasons to consider GraphQL than performance, which I cover in detail in TFA.

Hey HN,

We’re Fırat and Tolga, we are the builders Joospeh. We were frustrated by dozens of tabs in our browsers and endless search for high-quality articles and videos. At some point we were so frustrated by the fluff marketing content and piles of tabs in our browsers, we decided to create a better way to use the internet.

We come with this idea of an online directory for organizing and discovering great learning materials through collections (like learning paths, newsletters etc.). Basically, you can save and organize your articles,videos etc. in your library and discover and share collections as learning paths, newsletters etc.

You can easily search and filter any of your bookmarks from your library. Also, you can weekly newsletter from your recent bookmarks and the collections you have followed

Any of the content can be ranked by liking or disliking, also your likes and dislikes personalize your suggestions so you can find easily great articles and videos about the subjects that matters to you.

Now today we’re launching our extension, here’s what you can do with it:

- Bookmark any link to your favorites or your collections (like folders)

- Create new collections from extension

- Check rating of a content

- You can like and dislike any content from extension

I hope you like it. Waiting for your feedback on the comments :)
How Much of a Performance Boost Can You Expect with PHP OPcache Preloading?
Strongly agreed. 95% of the web's problems can be blamed squarely on advertising-based business models. HN does not have ads, so the focus is not on getting more users and clicks (i.e. generating outrage), and the excellent moderators are quick to punish harmful users, because there is no motivation to keep them around.
- Comments aren't executed or covered by a test suite so it's much easier for mistakes in them to slip by. A comment like "Close the file when..." when it should say "Open the file when..." could easily slip by review or when the underlying code changes. Same with typos and wrong names.

- When you're adapting existing code, misleadingly named variable names and function names are going to be quickly noticed and fixed as developers are forced to read them (unlike reams of external docs or big comments). If you name a function "close" instead of "open" by accident, someone is going to notice fast.

> Well that's an organizational problem. Personally when I do code review and I see a comment which is redundant or doesn't match the code, I immediately return the PR and tell the developer to fix it.

You can justify any misguided developer practice like this though. The question is "is this a worthwhile thing to spend time enforcing?" and not "is it possible to enforce?". Getting rid of manual checks is a good thing when you can too.
The worst part is often people don't buy their refrigerator, it comes with their house/apartment as a package deal. So you would literally have no clue that this is a thing until it happens. And in the case of an apartment, you literally have no choice in the matter (cant use your own refrigerator) if the apartment maintenance wont replace the filter.
Yeah Atkins was quite heavy. That said, I think it does a good job of being self-contained. You could more or less get 80-90% of what you need with only that text from high school knowledge. But without additional resources and teachers supplementing, it will probably be too gruelling.

I think that's more because physical chemistry is quite hard
From the PDF:

In 2019, we awarded our standard ongoing compensation to each of our non-employee directors, including an annual $75,000 cash retainer payable in arrears and an annual $350,000 GSU grant. We paid an additional $25,000 annual cash retainer and an additional $150,000 annual GSU grant to John L. Hennessy, our non-executive Chairman of the Board of Directors, given his additional duties in the role. We also paid an additional $25,000 annual cash retainer to Ann for her role as the Audit Committee chairperson.We awarded the above-mentioned cash retainers and GSU grants to our non-employee directors on July 3, 2019, the first Wednesday of the month following our 2019 Annual Meeting of Stockholders. The exact number of GSUs comprising the equity awards wascalculated by dividing the target dollar value of the award by the closing price of Alphabet’s Class C capital stock on the day prior to grant and rounding up to the nearest whole share. All annual GSU grants made to our non-employee directors vest at the rate of 1/48th monthly, beginning on the 25th day of the month following the grant date until fully vested, subject to continued service on our Board of Directors through the applicable vesting dates.

And then they have a table with concrete values for each director, on page 38. The median for 2019 is $428,298.

The power users outside of the MS ecosystem already left Windows a while ago you mean. A lot of mainstream tech tools & languages only have a medium support on Windows which is not really prioritized that much compared to the Mac & Linux versions. WSL is a big move to try to win those power users back.

Which of the modern startup founders have gotten into the Stanford PhD program as teenagers? Those people are extremely rare and there is far too much VC floating around to focus only on such talent. Most founders, while still outstanding, are not from that class of person. Also, due to the larger sums of money being thrown around, people can just do those things now and spend their time growing their business instead of optimizing it. In the VC funded environment, optimizing businesses lose out to competitors which grow the fastest.
It will be performing this indirection over localhost. I don't see it as much different from the indirection of SQLAlchemy. Yes, there is the question of parsing the GQL and so on, but I think that they're surmountable and fit well within our desired performance budget.

Performance is also just one of many reasons why this approach is being considered.
> it's perfectly reasonable to gate access to that value

It's also perfectly reasonable to distribute that information widely and without limits. The fact information is valuable to someone doesn't make it scarce. The harsh reality that creators need to face is that only the first copy need be paid for.

> I'm sure you wouldn't argue that anyone can watch a movie for free just because someone else made it

I would. Instead of charging money for copies of a movie, film makers need to figure out how to get paid before the movie is made. Creation must act like an investment, not a product. Maybe the answer is crowdfunding? Whatever it is, it needs to pay the creators before they start working so that the final result can be released into the public domain immediately.

> People have a right to own and control the distribution of their works that they invested in creating.

That's nothing but an illusion. Once the information is out there, it can no longer be controlled. People will copy it, distribute it, edit it, create derivative works, memes... And there's next to nothing creators can do to stop it. The work becomes part of mankind's culture. People infringe copyright every day without even realizing it.

"Creators have the right to control..." sounds like a neat idea on paper but it completely breaks down when put into practice. When authors try to "exercise control over their content", we end up with websites which disable right click and create annoying pop ups when we try to copy paste. It's completely ineffective and serves only to annoy people.

The only way to control information is to control all the computers that process it. Currently, it's impossible but not for lack of trying. In order to prevent infringement, the copyright industry is prepared and willing to sacrifice computing freedom: their ultimate goal is to prevent us from running "unauthorized" software. Programs that do subversive things like copy movies or play movies without checking for a valid license first would not be signed by the authorities and the processor would then refuse to execute such code. Therefore, the copyright industry is an existential threat to hackers and the free and open source software community. I'd rather sacrifice the entire copyright industry than computing freedom.

On the hiring side, we tried using LinkedIn during a recent hiring round of about 5 highly skilled C developers. We flipped through hundreds of LinkedIn candidates and exactly zero made it past the resume filter. Completely useless.

To me that reads as they’d send enough personnel to flood an area such that it would deter people from the worst aspects we’ve seen while allowing non violent protests.

So any troublemakers would think twice about trying to hit an area to sew chaos (looting, rioting, setting property on fire, etc.)
Wow, that is more violent than I expected!

I think both effects are at work. Thought experiment/hypothesis: If you detached the plate and merely held it in front of the fan blades, I think the fan would still rotate due to the decreased airflow on one side of the fan, but it would rotate less quickly since the force that moving air is applying to the plate would no longer be acting on the fan.
And that's the thing, the code _is_ the blueprint. What is code if not a sufficiently detailed specification?
In the US the biggest impact a board can have is the hiring and firing of the CEO. (And the threat of that) They give the CEO guidance, and check performance, but as a group they work through the CEO.

The CEO has to aggregate the needs of both the board and their directs (and customers and suppliers) into a coherent whole. Not an easy job as if everyone gets 100% of what they want the organization can’t function. (In a sense it’s like product management at the company level)
