The issue is usually less what species gets endangered or faces extinction, but the fact that this is not done for progress but for greed (be it humanity or corporations).

Destructively changing anything should be approached with extreme care, since you cannot un-extinct a species.

I'd illustrate it like what happens on Linux when you are approaching OOM situations. You can either kill other processes, not knowing what they did or if they were vital, or just stop doing what you were doing. And so far societies have usually decided that mines are not as important as raw materials at some point.
Ask HN: Doomsday Terminal – your thoughts
Hi guys,

just wanted to present my open source project: https://github.com/vasso123/DoomsdayTerminal

The name is just random, so don't ask why :)

On my daily job, I had many situations where I needed such a tool, but couldn't find one (for Linux). I've found a nice utility app for Windows, but for example when connected to a Linux server through ssh, and you want quickly to test some tcp communication with some other server or device, you're stuck with telnet and netcat basically, which just don't offer more advanced options.

So when I saw the Lanterna Java library I knew that was the right tool for the job :) For all Java haters out there, the plan is to package the application as a "native" one, using the new Java 9 jlink tool, so that you don't have to depend on the JRE installed on the machine.

I would like to get some feedback on the project, do you see it useful, and which additional features would you like to see in it?
The question is not well defined. If m is the degree of the polynomial, you want ∀ i ∈ {0, ..., m}, c_i ≥ 0 and ∃ i ∈ {1, ..., m}, c_i > 0. Otherwise the solution is either trivial or not unique.

> Do you find this interesting?

Depends. For a pedagogical tool in 5th to 8th grades, maybe.

There may be some reason it is a compelling exercise which I am not seeing though. So, you might want to explain why you find this interesting enough to post it twice.
> We can’t preserve everything anyway...

Sure, so we might as well just go scorched earth, I guess. Nothing lasts forever, better destroy the environment then. Hey, clean water? Nope, just a fantasy. Clean air? Impossible. Living in balance with the other species that share this planet? Untenable, so we’d better just kill them all and get it over with in the name of profits.

"It is difficult to get a man to understand something, when his salary depends upon his not understanding it."
> We can't preserve everything anyway, and there is nothing to be proud of in keeping a dying species in the world.

That doesn't mean we shouldn't try. And many of these dying species are a result of our rape of the land [0].

As more species die, more will starve. We live in an interconnected environment, and harmful effects to even the smallest of species have repercussions for others and even us humans on the top.

We need to be better stewards of the land we use and share.

I'd be interested in looking at the categories of this increased consumption as well.

Maybe they bought needed underwear they couldn't afford before or something that's a necessity.

Maybe they bought a laptop which provides them massive value as far as information goes.

We have to be careful of interpreting these results based on what we 'expect'.

Unfortunately, cost of the development boards is in no way the problem blocking wider use and knowledge of FPGAs.

FPGA tooling is stuck in the dark ages. FPGA pipelines are windows-only, the development environment UIs look like a toddler was given access to VB6, and the licensing is crazy.

Lattice semiconductor will give a free licence for iceCube2 to a resident of the USA in less then 24 hours but will deliberate for weeks over giving one to someone in Australia (so you should just lie and say you live at the white house, that's what I did after three weeks of no response to my licence request).

Xilinx's free licence for ISE states that by using the free licence you agree to let ISE upload all your FPGA code to them and they get to use it for whatever they want. It actually states directly in the licence that if you don't like that you should install the software and then airgap the computer from the internet forever. Cheeky as hell in my opinion. I installed mine on a virtualbox machine and then removed the virtual network card.

The reality is, FPGA manufacture and tooling is stuck where 3d printing was a decade ago, but for slightly different reasons. Designing and manufacturing FPGAs is pretty high investment which is a major barrier to entry for competitors (the same way patents was for 3d printers). Since FPGAs are desirable for many high end tech companies, it's more profitable for Lattice/Xilinx/et al to charge a small number of companies a squillion dollars for high end development boards and commercial software licences than it is for them to lower the barriers of entry and sell to a wider audience.

I'd put a lot of support behind an open hardware FPGA design, even if it was rather shitty in performance, cost and/or features to the current top of the line FPGAs.
The other Autodesk products use DirectX rather than OpenGL on Windows since years back. Apparently a big reason for this was the sketchy OpenGL driver support on Windows, which caused issues with many consumer-level graphics cards.

So this is not necessarily an issue with Apples deprecation of OpenGL, but could as well be Autodesk wanting to move also the Alias product to DirectX only.
Pretty much any mine? I've seen proposed mines get shut down by that sort of environmental activism.

Bar a bit of recycling, everything that is metal or stone and most of our energy comes from some sort of mining activity. The cheaper it is to extract, the better it is for rich & poor alike. If I have to choose between losing a species of beetle and people freezing in winter, the beetle is in trouble.

Technology is lovely, but at the end of the day the more natural resources we extract, the better the quality of life of people everywhere.
That's well and good, but the article linked here is still garbage because of how meaningless the idea of parking spaces/resident actually is. I'm not saying Jackson is a good place to live, but just because you can make up a stat, doesn't make it insightful. The authors of the summary in question clearly didn't try to think about the situation holistically, just chuckled to themselves about their silly number.
"Like that" as in trying to educate? Too bad.

This described something isn't "massively parallel" and couldn't scale up. I'm happy with calling the big Sunway- and PEZY-based systems supercomputers and hope that Neo turns out well.
I don't see what is "passed on" "more than genetics" when reading the actual studies:

https://www.cell.com/developmental-cell/fulltext/S1534-5807(...

https://www.cell.com/developmental-cell/fulltext/S1534-5807(...

Skimming through them, I only understand that the sperms go through different phases before the fertilization and that the scientist observe some details of that now. That the whole process is quite complex was know since a while.

Maybe somebody who understands more can explain here?
Perhaps your definition of "human progress" could expand a little, to include "learning to be ecologically responsible"?
No, any extra height to pump water up compared to the height of the dam is just wasted power. They wouldn't do that without a good reason.

My understanding is you can't just stick an inlet on the river, otherwise you could only pump water up when the dam was running (defeating the point). You need to build some kind of reservoir.

Additionally, with hydropower it's not enough to build a dam above your generators. You also need to get rid of the water exiting your generators fast enough. If there is any restiction on the outflow, the back pressure will decrease the generation capacity.

My guess is the distance is needed to meet these requirements. Enough space to let the water slow down, then enough space to build a reservoir.

> Is there a reason Amazon doesn't limit reviews to verified purchasers?

When the Amazon review system was created back in the 1990s, there was no requirement to purchase the item. That led to people often reviewing books they got from the library, or books that they already owned in their home library before Amazon existed. There were no scammers around to ruin things yet, and even if people weren’t buying every book from Amazon, they were still drawn to the site by these social features, the very vibrant "community" of book fans.

Over the past few years, Amazon has already removed various community discussion forums. Apparently, now that the site has reached a dominant market position, it feels that social features are no longer necessary to attract or retain customers. As part of these changes, Amazon has also reduced the visibility of non-verified purchase reviews on many listings. Still, its efforts are gradual, maybe it feels that completely limiting the review system to verified purchases would be too drastic a step.
That is my understanding as well, and the main reason why I thought he was just trying to scare me.

However, they can place me on the no flylist, but I believe that this is run by a different branch of the government.

> The logical consequence of the belief in people being unable to defend their minds against elaborate ads is that we should abolish democracy.

Totally! And it’s a disheartening thought the more you think about it. How can people who, in their majority, do not have an informed opinion on _any_ issue (not because they are necessarily stupid, but because for almost any given issue there will be fewer people who have thought really deeply and clearly about it or were specially trained to think about it than those who haven’t) be trusted to make a choice?

And, to continue this bleak train of thought, why should your fate as an individual be governed by the choice of the uninformed?

It is all very depressing.
I think you'd find I'm on the pro-extraction end of things.

I'm just not convinced that the costs of restraint are particularly high, especially given the capability of modern industry.
The basic problem is astroturfing.

In politics if I create a bot network to artificially boost the more divisive tweets, over time the entire political network may become more polarized and toxic. And it would necessarily elevate fringe candidates who are most equipped to deal with chaos. Its absolutely fascinating that you can create a real world riot just through a simple algorithm over time.

And politics is probably small potatoes compared to the commercial applications. Imagine if you can make your product go viral, suppress all dissent and at the same time sabotage your opponent's user base. And all that for very little investment. That is an unbelievable competitive edge.

So, the question is how do you stop this?

The internet is designed for anonymity and is not easily traceable across national lines.

So, if a Chinese/Russian company is involved in massive botting, what can you even do, except hire them yourself to stop your opponents gaining an advantage.

I am struggling to see a solution or how government involvement doesnt make this problem worse.

I disagree....where I am from(UK) the cinema is so incredibly expensive that I pretty much only see movies that I know I will like(big blockbusters) because I cannot risk spending £16 on a ticket and not linking the movie. And yes, you can sometimes buy tickets for £6-7, but that's usually only on specific days and times, which doesn't always work for me. Regular cinema is incredibly expensive.
The average person doesn't compare the source, and the average person doesn't read the bash script, for them it's the same thing.

For the person who wants to read the source, I'll argue that pressing backspace 6 time to delete "| bash" is _more_ straightforward than looking up the source for a PyPi package.

There's only a subtle difference between a PyPi account and a server (script hosted on Github?) being pwned.

Though yes, I do believe they shouldn't have used an URL shortener.
Can't blame them for not wanting to port to Metal.

However, I found that out from the comments on HN - because when I opened the page the article was covered by a full popup informing me that they 'care about my privacy'. And then they probably wanted me to agree to being tracked. Not sure because I instaclosed it.
When we say "HPC" generally, we're talking about being able to run computation that isn't embarrassingly parallel. The bulk of work on typical general purpose systems tends to be DFT-type materials science and finite element/CFD engineering. Obviously if you have a special purpose system you can made different trades-off.
Endangered species are a proxy for biodiversity as a whole. A fairly objective Schelling fence [1] people can agree on. (But we should—and do—have other metrics as well to avoid Goodhart's law.)

>If I have to choose between losing a species of beetle and people freezing in winter, the beetle is in trouble.

Yes but which mine is it that's 'keeping people from freezing' exactly? I would totally support a mine if it kept people from freezing to death, I just don't see any evidence that one or two or three new mines are actually going to do that. Commodities becoming cheaper is good, but it's not infinitely good and other things, like preserving just one weird beetle species, are important as well.
I use the favorite link, as mentioned in the other comment, but I also use Pocket, and its chrome extension. I have the app on my phone, and my e-reader downloads my pocket saves for me to read offline.
(just adding as a comment because the original text was too long)

Maybe I reached my goals too quick and without much hassle at all and therefore can't really value what I have.

Changing my life circumstances again would probably not solve it. I always loved and needed to do new things. If I would quit now, I feel like I would lose all credibility. I mean, who wants to hire someone who even leaves his own company only because he is not happy? If there would be at least a reason... But there isn't. Even financials are working fine.

Sorry. Just spitting out what is in my head, unsorted and unstructured. I'm not even sure what I'm asking for with this post.

What's wrong with me?
If you read until the end, you will see the section entitled ”How much does accuracy cost?” were they explain that the difference that matters is the cost of the fixed point implementation.
I use Instapaper but I have also recently started trying out Pocket. These tools are effective since it is very easy to set a bookmark let to save articles for later.

One great thing about them is that they allow you read articles offline and without ads and in the format you want such as black background.
The advantage with pumped storage is its fast response you can turn it on in so much faster than other types.

The Endangered Species Act is not a good way to protect endangered species. It bars consideration of cost at any level, and basically destroys the property rights system thereby providing incentives to preemptively destroy habitat.

Anyone who wishes to understand effective ways of protecting species needs to think a little about cows and elephants.

I’m not sure. I know the bioavailability of magnesium citrate is much better than that of magnesium oxide, due to the bad solubility in water of the latter (and supplements with magnesium oxide are thus next to useless). That suggests Mg ions already present should be readily absorbed.
The "background" rate of extinction, i.e., pre-humans most of the time, is estimated at about 1-5 species per year. Currently, humans are causing 100 - 1000 times the background rate (10+ per day) [0, 1]. Do you feel that it is reasonable to allow any animal that isn't adapted to having its habitat destroyed by humans, go extinct?

In my opinion, given that these animals took millions of years to evolve, and if their threat of extinction is directly related to our activities, it seems reasonable, that as a progressive, intelligent species, we make efforts to preserve them for many worthwhile reasons.

I have enjoyed using Ansible, but I learn and deliver more using simple bash script. I integrated several "concepts" from Ansible in my scripts: idempotence and vault. If my infrastructure were larger, more complexe or required frequent modifications, I would reconsider Ansible again.
I can think of two reasons to protect species: one practical, one moral.

The practical one is that humans rely on ecosystems being the way they are, and that unbalancing them disturbs our interests, particularly in agriculture. We also rely on a diverse plant ecosystem to discover and develop new medicines.

The second argument is more values-based: that ecosystems and animals have value in and of themselves, axiomatically. If you don't appreciate this argument perhaps you never will: it's not something that draws on more fundamental principles, it just is a principle itself. Similar are arguments about speciesism and the active right of sentient animals to survival: it's probably one of those things that can't be deconstructed into more basic, falsifiable arguments. I'd suggest the same applies to the claim that human progress is necessary and valuable - it doesn't seem provable, just an instinctual belief.

There might be a third argument: that protecting the environment helps economies optimise for longer term gains. One of the things holding back sustainability has been the relative cheapness of dirty alternatives - so restricting mining might encourage more creative means of manufacturing. And frankly, if all you're doing is mining cadmium for smartphone batteries, you may not be doing the human race much good to begin with.

This is FALSE again, they go against people or sites that publish schematics or instructions on how to fix things, they go against people that want to buy replacement parts, they say is for keeping the brand standards but is for the money.

Imagine your side mirror of your car is broken(say a Ford).
Now imagine Ford is not allowing you to buy any other brand of mirror to replace it, you can't even buy the Ford mirror to replace it yourself either, you must go to a Ford shop pay 10x more for the mirror replacement but in some cases the guys there say that is to expensive to try replace only the mirror and they will change the entire car body but all is fine if you bought the extra insurgence package, if not you will pay 25%-50% the original full car price to have it fixed.

Again, inform yourself, this thread has many references and be honest with yourself, you can like Apple for the things that they do right and don't try to excuse them for the things they do wrong.
How about focusing on a domain rather than languages? Say you're interested in Natural Language Processing. Pick a language and become an expert in NLP only. You'll be valued for your domain knowledge even if you're not that good of a programmer. That way you're not pressured to pick up a handful of languages, which pretty much do the same thing anyway.
Yup...this is how I do it too actually for all sites
Conservation is tricky. One can usually make the argument that things will probably fine without <insert species> or that dumping a little more <insert environmental toxin> won't cause immediate disaster.

But have you ever played pick-up sticks? That's basically what we're doing with an environment we don't understand as well as we might want to believe. Sure, your particular possum might not be important. In all fairness, it probably isn't. But remove enough sticks, one at a time...

Yeah, maybe but I don't think you can 100% trust extensions, an extension can read all the content on your pages, they can do network calls so it is always a risk.
Actually I think that doing all the projects I want to do during a staycation is perfect. I know I have a ton of time to do them, and I can actually get them done. Instead of stressing and using up my weekends or weeknights doing them.

I’m actually taking a staycation later this month and that’s my plan.
"We can't preserve species over millions of years, so we might as well make them go extinct now" is not a good argument. It's like saying "we can't stop people from dying eventually, so it doesn't matter if I murder someone".

Even if you don't care much for animals, which is fine, you should still be worried about preserving biodiversity. We don't fully understand all the systems at play in an ecosystem, and killing some "useless" possum can have cascading effects that humans won't find favorable in the long run.

You can put a mine somewhere else, but you can't bring an extinct animal back to life.

No raising necessary https://www.saultstemarie.com/attractions/soo-locks/
> without code being involved

When you perform a network request you cause code to be executed. The code on the server is designed to respond to the request, in the same way as any local cross-process call responds to a request (including a kernel system call).

The key difference is not in the trigger, but in the measurement: measuring cache timing effects is more tricky when you can only interact with the target machine via a relatively high latency (and highly variable latency) channel such as the network. The new attack here shows how this can still be done probabilistically.

If you wonder how you can flush the cache over the network (without code involved) the answer is the same ad the answer to this question: why can't spectre be solved by just restricting the ability to issue a cache flush instruction? You can effectively flush the cache by performing more requests that cause other stuff to be loaded in the cache and evicting the parts you want to be evicted.
The Science of Creating Fixed Components on Scroll with Vanilla
Exactly, on the scaling, but even then you probably won't see potential problems with, say, deadlock, that may hit you on a real system. You can't stress latency enough, as you'll now if you've ever seen something like cp2k limping over TCP/Ethernet.

By the way, if you want to simulate performance of real coes on real systems (as you should), you use programs like dimemas, simgrid, and others with real or projected parameters.
