When I did my Pitman typing qualifications in the UK in the late 90s, 2 spaces was mandatory. That is where I learnt it from, and still keep doing it to this day as muscle memory.
Some (maybe most) people find it easier to remember and comprehend things they can vocalize, so using an inscrutable character, even consistently, can cause problems.
How can we be sure it was from the fish market? We have to take China's government's word for it. Even though many of the original cases were not tied to the market, and then this is how they handled it.

Your post definitely contains some good tips! Thanks for sharing!
That's not how proofs work. I can look and see negative cases, but you need for than that to show a net negative effect on society.
That article has 1906 (her engagement as cook in the Warren household) to 1932 (her paralysis) as the period of her infection of others, assuming after her paralysis she didn't infect anyone else.

That's still not 38 years; it's not especially important a point - she infected others over at least 2 extended periods amounting to mor than a couple of decades in total.

It's interesting to me, I thought nih.gov was a scientific publication but at least one part of that document appears to be opinion asserted as fact (~"she never intended to abide by the conditions of her release").

Does this exist for time numbers?

I wish Telegram used such a thing. Someone not seen for 1h59m is 'last seen an hour ago'. Even just showing the actual time would be more helpful IMO - it displays it at the top right underneath (iOS) or very near (Android) the system time anyway, I don't know why it's thought to be a good idea to remove so much information.
Ask HN: Which are some Covid-19 simulation models that are accurate?
I posted this recently - https://news.ycombinator.com/item?id=22981283

Also, there a model which Trump is following that predicts 80k American lives will fall by August 2020 to COVID-19, which is turning out to be prophetic.

Are there other COVID-19 simulation models which have turned out to be presciently accurate?
Playing Kerbal Space Program helped me a lot to get a (more or less) "intuitive grasp" on orbital maneuvers including "sling shots". I can highly recommend giving the game a try if you're interesting in rockets and interplanetary space flight. Even though it looks like a game (and can be hilarious fun at times), it's really a fairly accurate space flight simulator.

How are they measuring declining IQ over time? IQ tests are regularly recalibrated to mean=100 and std=15. That opens quite the can of worms for comparabilty in all sorts of ways.

For this sort of dough you may need e.g. 1.8g of yeast (that's the actual quantity I used for the last dough I made). It depends on how much flour you make, of course, but pizza doughs with long fermentation use minute amounts of yeast. If you use 1.6g or 2.0g instead of 1.8g, your pizza may be ready twelve hours too soon or too late.

I bought a second kitchen scale to deal with the minute quantities, since my old one is accurate to only 1g.
That's right. It has to do with the dimensionality and topology of the language syntax, not just how it looks.

C++ is not a visual programming language, no matter how much you colorize and pretty-print and fold it, because it's represented as a one-dimensional stream of characters, one after the other.

Excel is a visual programming language (and one of the most widely used programming languages in the world of any kind, visual or not), because it's represented as a two-dimensional grid of numbers, expressions, strings, relative and absolute two-dimensional references, and it also (though no not necessarily for the definition of a VPL) supports all kinds of graphical attributes, colored text and background, fonts, text styles, formatting, boxes and lines, freezing and grouping and outlining rows and columns, embedded graphs and graphics, etc.
I would compile the C code with the -S option to output your C code as assembler, and then compare them to see what decisions were made by the (pre)compiler that made the compiled C code run faster than your hand-wrung code. The code is short enough that you should be able to relate the different parts and easily see the "improvements".

This is how I learned to program assembler for Linux. I already knew TASM / MASM / a86 assembler languages for DOS/Windows - all similar but different in their own regards - but gas is a different un-backward beast, and of course the system calls are totally different between Linux and DOS/Windows.

For example, here are 6 different ways to program helloworld on an ARM cpu (Raspberry Pi) running Raspbian Linux: https://github.com/ksaj/helloworld I kept each of them as close to the same as possible, so that it is easy enough to see the differences in how each call is set up before execution.

I'm sure if you added timer code before and after the example code, you'd very quickly discover which methods are more optimal and then begin to dissect why that would be, and how to use that knowledge in future programs.

Keep in mind that the order of opcodes will impact execution speed, because of the many techniques modern cpus use to speed things up (branching, prediction, encoding techniques, entirely rewriting opcodes to something else with the same functionality - eg, most compilers understand that mov ax,0, sub ax,ax and xor ax,ax all do the same thing), etc.
Feynman definitely had some undesirable features, and he probably should if nothing else be re-examined as the poster boy for American science, but yeah, most articles criticizing him seem to be from people who haven't read anything he wrote.

There was an interesting article in The Baffler a little while ago on his polarizing history and personal views. I don't really agree with the conclusions it came to (it was very much of the position that he was undeniably irredeemably awful), but it was really the first long-form critique of him that seemed like it actually was familiar with the target, and has really been something I've thought about every time I've seen Feynman mentioned since, in any context.
This seems to be a direct outcome of globalism on digital steroids. Globalism increases the pool of people everyone uses for social comparison. Small scale achievements become negligible as they provide no sense of social status.
I was really impressed by remove.bg but hate uploading my pictures to who-knows-where. I looked around GitHub and there are several projects to remove backgrounds from photos but hard to judge the quality without trying them. Most were some python blob with murky or no instructions on setting up. But give it a few more years and I’m sure there will be a gimp plug-in.
While Docker is already offering 'host.docker.internal', what is the reason for this blog post?
Yes, I read about that, but free software is always a bit of a struggle.
Why again are explicit `min` and `max` faster? Is that GLSL specific, and (unlike say C++, where std::min and std::max are just `if (__a < __b) return __a; return __b;`) the compiler won't be able to turn a one-line conditional into an ARB MIN or MAX instruction?

This is a really interesting technical concept.

Capturing high-quality audio in a meeting room for videoconferencing is a notoriously complicated problem.

Microphones are crazy sensitive and pick up things like footsteps and conversations outside the door, shuffling feet and tapping on keyboards, and construction and HVAC noise like you wouldn't believe.

So filtering those things out, and then capturing the best quality audio from the current speaker, and trying to get everyone's voice at roughly the same volume whether they're sitting directly across from the microphone or are piping up from the corner of the room...

...and do this all while cancelling 100% of the echo that might be coming from two or three speakers at once...

...it's an insanely hard problem. Beamforming microphones absolutely help in a huge way, because if you know the speaker's voice is coming from 45° then knowing that any sound coming from any other angle can be removed is a really helpful piece of info.

Now, with beamforming microphones, the precise relative location and direction of each mic is known. The idea of creating one big beamforming mic for the room out of people's individual mics is... insanely hard, but super cool.

It's interesting to me that this article is about measuring the quality of voice transcription, rather than about the quality of audio in an actual meeting. But I suppose the voice transcription quality measurement is simply a proxy for the speaker audio quality generally, no?

This could actually be a huge step forward in not needing videoconferencing equipment in meeting rooms. So far, one of the biggest reasons has actually been dealing with echo and feedback -- when people are in the same call with multiple devices in the same room, it tends to end badly. But if the audio processing is designed for that... the results could actually be quite amazing.

And it's well-known that the "bowling alley" visual of meeting participants (camera at the end of a long conference table) isn't ideal. If each participant has their own laptop camera on themselves, it could be a vastly better experience for remote participants.

That’s true if you’re familiar with programming and know how CloudFormation works. Adding a framework or abstraction layer requires certainly more skills from your end. This article is more suitable for people who want to deploy small projects quickly and don’t want to invest time to learn a framework.
Yes, these things happened to the military personnel but that's not a military dictatorship. In the military dictatorship, the coup succeeds and the military personnel rape and torture people.

In Turkey's case, the military attempted a coup, failed and the civilians did these things to the military.

Pro tip: The guys with the uniform are the military ones, they got beaten on the streets when attempted to establish a military dictatorship.
The series is just a bunch of propagandist BS in a very nice package. The amazing number of factual errors given that not only documents but documentary footage are available along with internationally verified reports.
> (although, that's not technically true since irccloud does all the things you just mentioned)

Yes but then you're not using IRC, you're using IRCCloud. Its features are independent from the backend that is used; they could switch to Matrix or XMPP or a proprietary protocol for that matter, and the features would still be there. You can't expect the one you talk to to have IRCCloud and tell them "just search in the conversation history, it's there" because the protocol doesn't allow it.

The GP's answer is correct, Slack does a lot of useful things by default. That's why people like installing Ubuntu or even Debian but don't want to take time to setup an Archlinux or a Gentoo anymore: it's fun, but if I just want to do something other than tuning my install I'm not going to consider those distributions.

Now, the question is, does that mean that LFS or any bare distribution "lost" to, say, Fedora ? No, because they are meant for different needs. I'd say it's the same for IRC: it's best suited for people who are not interested in the full history and want to talk to people in a synchronous manner, people for whom text is a more than good enough solution and aren't necessarily interested in binary exchanges, people who like pseudonymity, etc
Exactly the increase in "all cause mortality" is the most honest we have at this point. But they say that number often gets adjusted in the weeks after (not sure why that is happening or acceptable).

Belgium unveil plans to lift lockdown
Is there a source that says they were using PCR testing? The article seems pretty light on technical details.
The key words in the parent post are 'for me'.

Imagine you have a single core compilation process that takes two minutes that you must run 50 times a day. This can happen. Ten percent brings 12 seconds per compile or ten minutes a day. This might not sound great but it means you can get an extra five compiles done. You can also get increased likelihood that you can remember what you were working on. Therefore the marginal gain in single thread performance is well worth having in this use case. The expense of genuine Intel becomes worth it even if you don't have so many cores.
These robots are GPS tracked, not to mention lockable and remotely deactivable. All you looted was some plastic, useless cameras, circuit boards, and mini wheels as well as a GPS tracker. Break it open and you'll find $25 worth of food inside.

> But on that day in August, when Muddy Waters tweeted that it would release a report about an accounting fiasco at a London-listed firm, Block noticed an interesting development: the stock of NMC Health dropped. “We had tweeted in advance an innocuous comment about our intention to initiate a campaign the next day on an unnamed London listed firm. NMC happened to drop significantly on the tweet. That’s a pretty strong indication that the market knows something isn’t right at the company, so we took a look….” Block told ET Magazine in an emailed response. What they found was not pretty.

That's the most interesting 'event study', as it were, I've heard of since the Challenger or Alchian's nuclear bomb market study.

It's amazing the things that the market 'knows'. I sometimes wish that event studies could track down the specific traders responsible and understand what exactly they know and how they learned it, because it otherwise is such voodoo.
Barely, if at all. Not all benchmarks have been done with all exploit mitigations we have today. Also AMD is cheaper per performance.
You write very well.

But this: "Enjoying your life and doing things that you take pride in are secondary to the all-encompassing drive to impress people who know nothing about you. "

I'm sorry to say is a vicious new Anglo/American trend that used to be only for specific groups 30 years ago and has metastasized ... sadly into everything.

Please don't let it steal your youth.

Consider that most of it doesn't work, that people have pretty good subconscious BS filters. Just be yourself. At the office, obviously a little more than that, but even then worry less about 'personal brand' there is nothing to gain.
What you’re describing isn’t managing up. It’s fraud. You’re misleading your boss about material aspects of your job.
"The series ends with an epilogue noting that, while the official death toll remains 31, other estimates have ranged from 4,000 to 93,000, with some estimates climbing even higher."

This was the worst moment in the series. The otherwise pretty solid description of the event was tainted by that. I screamed at the screen. The correct statement would be closer to:

"60 deaths have been directly attributed to Chernobyl, and large careful consortia of hundreds of scientists concluded in the 2000s that "up to 4000" early deaths may occur from the accident across the decades, though they later revised the statement to say they do not recommend multiplying small doses by large populations to get large death values. Meanwhile, a few fringe groups and Greenpeace said 93,000 and Helen Caldicott says millions just because she feels that it must be that high. By the way, burning fossil fuel kills 4 million people every year by air pollution. That's a Chernobyl every 2.5 days, day after day. So even though Chernobyl was horrible, the dispassionate numbers show that nuclear energy is still extraordinarily safe compared to other major forms of energy production. Plus it is very nearly carbon free, which matters more than ever today."

The UNSCEAR group with the 4000 number is analogous to the IPCC. The 93,000 and beyond people are analogous to the anti-vaxxers. The HBO series gave them equal weight.

Look it up! It is truly shocking.
It may be the case you can put a new OS on the device without it being wiped, because the OS partition is separate from the user data partition, and probably unencrypted.

Anyway, a hypothetical alternative firmware couldn't just magically bypass the encryption. What it could have done, and I think this may only apply to older iPhone models as it's now handled by the Secure Enclave(?), is make it easier to brute-force the pincode (no lockout, less delay).

If you are running many single-threaded applications at once AND if you care about their performance. For example my Windows might run some background processes from time to time, but I don't care about their execution time, all I care is about my foreground application.

There is a huge volume of literature for astrophotography - I think most random hits you'd get on Google will be OK (the vast majority will be digital oriented). For example: http://www.astropix.com/html/i_astrop/toc_ap.html

I can probably give a better recommendation if you have a particular goal in mind. There are plenty of guides on how to take photos of the Milky Way with an SLR, but astrophotography is a broad (and quickly very expensive) field to get into.

If you're interested in a more technical angle, you can look at the Handbook of CCD Astronomy (Howell, 2006) which also discusses noise issues in detail. Nowadays we're moving to CMOS though. However when you go for astrophysics books they tend to focus more on measuring intensities accurately (photometry) rather than getting pretty pictures.

Although one nitpick with the article - tracking mounts do not follow the rotation of the Earth, they rotate in the opposite direction.
There are obvious(?) privacy issues and what not here. But ignoring all that for a second, it does sound pretty cool to be able to leverage all the little computers we walk around with.

Think of all those shitty little video clips people take at a concert. Could all those be combined to make some high quality panoramic video? Probably a lot of other cool applications that I can't even comprehend for now. What a time to be alive.
Most of the guides for digital will concentrate on post-processing, as the actual shot is quite simple, and you can tweak everything as you have instant feedback. If you can see the milky way with the naked eye, you need: tripod + wide lens (24mm on full frame is ok) with wider aperture, manual focus (using the display zoom function for best results) as autofocus on stars doesn't always work, manual exposure for something like ISO 1600-3200, around 20 seconds exposure on f/2.8, 10 second timer exposure, press the shutter and leave the camera to stabilize on the tripod.

The key is to find the places where you can see the milky way and to plan ahead - a moonless and cloudless night is important. There are websites[1] and tools[2] or that.

I take your point but there are downsides to restricting oneself to only Roman letters. In a few fields I've been a student of, there's a bias against introducing Greek letters. The downside is one does run out of letters. Eventually one needs Greek letters if one wants to not communicate in an amateurish manner -- either that, or one is forced to use multi-letter variables like "Eff", "Density", which are somewhat unwieldy, especially in complex expressions.

Also some Greek letters have such a strong conventional association with certain quantities that using Roman letters in their place can be more obfuscating, e.g. ρ = density, Δ = change, η = efficiency, θ = parameter, σ = standard deviation, μ = mean, τ = time constant, etc.

Notation is to some extent a function of a community's conventions.
Thats why we used to use to term Free Software... Now what open source really means depends on whoever uses it.
To expand on your point - I am starting to believe that the political correctness oozing out of teens and those in the early 20s today is actually compensation for a new form of selfishness that comes from being measured in real time on a global scale, and drives the non-stop status games you described.
The problem today is that the disinformation is also coming from official channels. Look at how much effort had to be put into countering a ""sarcastic"" statement from a White House briefing.

Perhaps the only way is to appeal to the enlightened self-interest of the tech companies. Ad spend has collapsed; perhaps they will realise that you can't sell ads if you let misinformation destroy society.

> Chernobyl is ultimately a deeply frightening story about the danger of refusing to accept reality in favor of political ideology. The Soviet Union provided many examples of this danger, but such refusal is not only a Soviet phenomenon. Chernobyl is a reminder that lies have a cost and, eventually, reality will catch up with you.

As a thought experiment, substitute climate change for Chernobyl and US for Soviet Union.
I don't think the salary effects who goes in jail or not. The only thing it could change is that people making a good living would be less likely to take risks and lose everything than people already at the bottom.

There isn't much to debate, Turkey is universally seen as a dictatorship and has a track record of doing very shady and questionable things (which are not even close to being acceptable in the EU or US). Feel free to believe whatever you want but you haven't provided any resources besides your own idea of what Turkey is and this view isn't backed by anyone besides Erdoğan supporters.
