Fossil fuels only account for about 70% of global CO2 emissions. Replacing all of them with renewable energy sources will lower emissions but also bring more emissions (e.g. from cement needed to build those power plants). Our current global economic system is pretty much single mindedly focused on exponential GDP growth. As long as this system persists, all that new clean energy will be used to produce more useless disposable gadgets, driving up more emissions from methane (from all the new trash produced with all that energy).
What we need to stop climate change is to lower consumption and to lower production. This is very much possible while also increasing quality of life. Technology can help with getting that into people's head, but a political will has to be there first, and that won't be possible without challenging the current economic system.

Gold is a crap hedge for equity selloffs. It's correlation is highly dubious and as in 2008, in this current case as well it actually sold off sharply with the equities.

Bonds are very much like gold in this respect, doubly so if you explicitly pick the bonds of a highly indebted country with a shaky economy, in the middle of a potentially massive pandemic - like Italy. Italian bonds as a hedge have been avoided like the plague by anyone with an ounce of insight.

On the previous iPad Pro keyboard page, they had this text: "The Smart Connector transfers both data and power between iPad Pro and the Smart Keyboard Folio — no batteries or charging required"

It's the same connector since the new one is backwards compatible with the old iPad Pro.

If you google "iPad Smart Connector pinout" you find previous discussion/speculation on the protocol

edit: the announcement specifically says the stand supports "pass-through charging, keeping the USB-C port on iPad Pro free for accessories including external drives and displays". So the pogo pins only have to have enough data bandwidth to send keystrokes, the stand won't give you USB 3 data
The thing is that you can participate in modern society without Google needing to track you. It isn't even hard to imagine.
Sorry not really an expert in Go.
Sure, it's a big part of life for many, but my question is whether it'd be better if it were cheaper. If all of the staff were replaced by robots and prices dropped by 20% GDP would go down, but society as a whole would be richer.
I ran a hackintosh for years. It used the retail OS plus some custom kexts. My last OS was Snow Leopard before I sold it. I got a real MacBook Pro with Lion and hated hated hated it. Hated it so much I started running Linux in a VM again and eventually switched to a Linux desktop again.

I don't know how well the modern macOS versions as Hackintoshes, but I suspect the community is still strong. The current challenge is probably around all the specialized hardware security and encryption chips on modern Macs, as well as the newer restrictions on signed/unsigned kexts and all the recent kernel/system API lock downs.
I'm surprised this doesn't mention Cauchy sequences. It seems to get close, but never quite hit the mark.

Anyway, a Cauchy sequence is one where the terms of the sequence eventually become arbitrarily close to one another; that is, you can pick an epsilon, an arbitrary small number, and after a certain point, the difference between elements of the sequence is less than epsilon.

The intuition is an infinite list of rational numbers which, when plotted, look like a ping-pong ball endlessly bouncing around a given point, getting closer and closer... to what? Well, it depends on the precise sequence, but that end-point might not exist in the rationals. If it's a_n/2 + 1/a_n, it converges to the square root of 2, but we've known for a long time that that's irrational, so the ping-pong ball bounces forever, from one rational to another, getting closer and closer to a spot that doesn't exist...

What if it did exist? What if all those spots existed? Well, if you have that, the set is now Cauchy-complete, also known as a complete metric space; if you have that, plus the field axioms (so addition, subtraction, multiplication, and division all work as you expect), plus ordering (so greater-than and less-than always work), plus the Archimedean axiom (no infinitesimal or infinite numbers), you have the real numbers. The reals are the unique Cauchy-complete Archimedian ordered field; every other set with those properties is isomorphic to the reals.
You can let the purely virtual "company" frame go bust (and the top management - would that really be a problem in such a case, and not the main purpose of such an action?) - and immediately use the assets and people to build new ones with minimal disruption. The factories don't have to be stopped for a single minute.

Not to mention that maybe letting them get so big was a mistake in the first place? Based on petty power games of "leaders" (in politics, finance and business) and not on technical necessities.
So all animals are in different species to members of their same sex?

I'm joking a little of course. But only to make the point that the definition of species taught in high school is very difficult to pin down. You identified one way. Even more common: not all organisms reproduce sexually. But also: some organisms (protists) perform sexual recombination separately to reproduction. And even for well known higher mammals (which is where the 'offspring must also be fertile' clause comes from), 'fertile' is by no means binary! A sexual definition of species is simple, but rather difficult down in the nitty-gritty.

It is always worth bearing in mind that species is a human classification concept, not a biological reality. It's not surprising that it has very grey edges.
I'm trying this out for code review on public transit.

My use case is that I batch a few small code reviews for the end of the day, and check on the status of some larger reviews that doing early reviews or working through edits.

I've previously been using the website on a mobile web browser, but it's not mobile optimized so touch points are fiddly, views need to be adjusted, long lines are hard to read, and I need to be wary about losing connection when adding a comment. Complex reviews sometimes take review of code in other files, jumping back and forth, so the mobile experience is lacking.

First impression is that the contrast for the red/green highlights seems a little low. I may just not be used to the color scheme though.
that's not how burden of proof works. you're the one making claims and assertions, not me.

You can call it 'one sided' and 'dogmatic' or you can call it 'consistent' and 'clear', seeing as it is a single entity that is broadcasting this opinion it makes sense for that single entity to be on it's own side of the argument.

The larger discussion can be seen in open core, open source, shareware, proprietary software, etc.

We are too used to scizhophrenic political parties with opinions all over the place. To the point that if there is a political party with a clear agenda then it is 'dogmatic' and 'one-sided' (hello extremists). The whole point of a representative democracy is that you follow the school of thought that represents your beliefs, if you can't trust any organization to stay true to their principles (hello startups getting bought by FAGMAN) then the whole system has lost it's foundational precondition (rendering it meaningless). For this reason I am glad to see FSF and GNU stick with the dogma they represent, practice what you preach.

I kind of feel like this is a similar discussion as whether to separate church and state. One is clearly dogmatic while the other is supposed to be a platform for (essentially religious) discussion. The problem is that the platform has to be grounded in some principle and then you've got dogma again.

Another manifestation is decentralized vs monolithic... Free software is about finding the principles to base government on so that religion can be discussed freely (policies diverging and converging). The technical problem of managing that is a version control system. I'm still waiting for them to become like governments but Subspace was launched yesterday and it is definitely in the direction of it.

I'm an epidemiologist and I think excessive testing doesn't help people, so it is definitely not just doctors. False positives can do real harm, including killing people if it leads to unnecessary treatment like surgery.

You need to think about a tests Postive Predictive Value and Negative Predictive Value. The PPV is the number of people who get a positive test who have the condition divided by the number of people who get a positive test who do not have the condition. When the PPV is low the test can provide functionally no information. Now the important thing to remember is that the PPV changes based on the prevalence of the disease in the population, so a given test could be good for some people and bad for others, all depending on their base risk.

Good. I'm hoping this will hurry along Dell's new XPS 13 Developer Edition configs with 32 GB of mem, 1080 display (I prefer battery over 4K) and linux. I have been itching to throw money at Dell since that was announced in January and here we are. Granted, the pandemic obviously hit their supply chain so I can understand.
We've never had hyperinflation in the US. We've had high inflation, but never hyperinflation. And we've had very low inflation since the 80s, including during the decade-plus period of practically-zero interest rates.

Hyperinflation is a completely different issue from inflation, and it's kind of odd for it to become the monetarist bugaboo. When the US has a massive war debt payable immediately, or a complete economic collapse that the government decides to cope with by price controls, then you'll see hyperinflation. But then, hyperinflation will be the least of your problems.
Embraer obviously isn't quite a Boeing or Airbus but their E-Jets seem like viable narrow-body jets. Now if the argument is that the USA isn't ok with all of the big jet manufacturers being foreign, then yeah, they have to bail Boeing out.
I wonder if you could combine the camera data with the lidar to make detailed real estate virtual walk-throughs.

Also, just as the Kinect allowed for some makeshift motion capture / animation, maybe the lidar could allow for some makeshift 3D modeling.

This seems to be like an answer to the "Can we just have the 2015 MBP with updated hardware?" question. Pending benchmarks, this could be the light at the end of the tunnel for a lot of users that don't need more than 16GB RAM (I'm still scraping by with Docker on my 8GB Mac and a lot of SWAP).

You could also look at it like this:

We want this general property to hold:

sum([ sum(x[0:n]), sum(x[n:]) ]) == sum(x)

define sum([]) (n = 0) so that it holds

It works the same for prod, all, and any, and gives a hint as to what the answer should be if there were things like union(sets) (the empty set) or intersection(sets) (the universe, or union of all sets)

FWIW, the German federal government (of all people), is organizing a distributed hackathon this upcoming weekend: https://wirvsvirushackathon.org/

Seems like it's supposed to be (mostly) in German language as well. If they do and market this right this might actually be an opportunity to get non-tech people to contribute important PROBLEMS that can be solved by tech right now, so we don't just get another few dozen news aggregators and case tracker dashboards.

In theory it would be a headless, modular, user-upgradeable mid-range mac - essentially a low-end Mac Pro or prosumer machine targeted towards gamers, enthusiast developers, DIY artists, etc.
The problem is that it ramps up by 250 Mhz increments, over a period of several seconds, and that can be extremely noticeable in some workflows.

I went from an 6700HQ (2.6 Ghz base) to a 10710U (1.1 Ghz base) and the difference is definitely there, and it's jarring enough to the point where I kind of regret it. It feels like a huge step backwards, despite the latter CPU being four generations ahead.
I'd happily do away with web browsers and use only native programs for each site I usually visit. For instance, when I still used reddit, I did through a fantastic command-line program called rtv [0]. I'd most definitely use something similar for HN, or any other platform--Wikipedia, for example, or ArtWiki, or MUBI. We certainly don't need a web browser as it is conceived today.

Maybe tall people are precisely as confident as they should be, and it's short people who have issues. e.g. "Napoleon Complex". I've personally met more than a few people who fall into this phenomena. It's not a trait that's compatible with good leadership skills. As for why this might be the case at all, I'd guess it has something to do with us being glorified apes.

> In 2018, evolutionary psychologist Mark van Vugt and his team at the Vrije Universiteit Amsterdam found evidence for the Napoleon complex in human males. Men of short stature behaved more (indirectly) aggressive in interactions with taller men. Their evolutionary psychology hypothesis argues that in competitive situations when males, human or nonhuman, receive cues that they are physically outcompeted, the Napoleon complex psychology kicks in: physically weaker males should adopt alternative behavioral strategies to level the playing field, including showing indirect aggression and coalition building.[10]

Of course these are generalities and you can find many exceptions, but the same is true of "managers tend to be taller"; that too is a generality with many exceptions.
The internet is still not considered a utility in the US.
So, it's not just regulation that blocks progress, many times it's lack of regulation.

There are a lot of people in the US still without reliable internet. Thanks to a lack of basic regulations on an essential utility.

That 3-6 month projection of operating expenses goes out the window once an emergency happens. Business require many more things to sustain itself. The recommendation is good for every day people because the actual cost to keep a healthy human sustained is actually pretty cheap (food, water, shelter). A business does not have human needs, it might need oil, metal, ores, chemicals, etc. to do its job. If the prices of those things spike dramatically, your 3-6 month emergency fund could quickly turn into 1-3 months.

Obama's biggest fault was that he didn't sell the American people on the inarguably excellent deal he got on the bailouts. The American people did profit off of those and most people don't know that because he didn't make a big deal about it.

Conversely, Trump, if he knows nothing else, knows how to focus doggedly on what's going to excite his base. If he can sell his base on the idea of loan-sharking Boeing (which is a legitimate strategy), then he'll come out looking like a winner, despite the fact that he'll have done the exact same thing as Obama.

Remember, never let your accomplishments go unrecognized by those you serve.

> The Triton chip will have eight memory controllers supporting memory running at 3.2 GHz, which is the same number of controllers in the Vulcan chip, which maxxed out at 2.67 GHz memory speeds. That’s a 20 percent increase in memory bandwidth, and the question is how that will balance out against the high core counts in some of the Triton SKUs.

96 cores, seems like it would be tricky to keep them busy with modest memory throughput increases.
So then the real problem is the debt, most likely that US corporate debt is given special tax treatment.

People want to get all pissy about this, and come up with all kinds of contrived punishments for the offenders. I’ll grant that this is an awful looking situation, but the most cost effective thing we could do is just learn the damn lesson finally. Don’t give companies money in boom times, keep it around for when a true unexpected disaster strikes. It literally requires no work, no new bills, just a memory that lasts a little bit and some introspection.

So think of care in this case being a pipeline, and right now the bottleneck is ventilators. Once we solve that, we may well have other bottlenecks, but right now this is the main one.

Well designed modern ventilators once set require minimal attention, and the overall settings for most COVID cases seem to be well understood from what the literature has suggested.

In terms of bacterial infections, it depends on the type of ventilation used and there are some variables here, but regular ventilator sanitation procedures should be fine, and currently have proven to be fine.
As I wrote below, gold has been a very dubious hedge for equity market crashes. As a matter of fact, in the last 2 decades, gold sold off with the initial market panic and it only started appreciating with the equity recovery.

Truth is that very if (if any) people understand gold, and it's use as a safe haven for market panic is highly questionable. It has certain correlation regimes with bonds and inflation, but given the sparsity of data on market stresses (they are by definition rare events), it is very difficult to draw any sound conclusions.

I explicitly exclude any events pre-2008, as the world now is completely different. The only thing that perhaps translates from the pre-2008 environment to our current situation is the magnitude of the selloffs, but everything else is different.
