>Now, after one of the longest bull market runs in history, the road ahead is again uncertain.

The rumors of this bull market's death have been greatly exaggerated. The DJIA is still up over 18% over the last 3 years, or ~6% annually; barely a percent below average. The NASDAQ 100 has almost completely recovered its' losses from the initial COVID-19 crash. Major drivers of the market over the last 10 years like $FB, $AMZN, $MSFT, and $AAPL are through the roof. Granted that a lot of this is fed meddling, and yes a lot of people from the service and hospitality industry are out of work, but the primary engine of our economy is humming along. I would not be surprised to see a record Q3 this year.
So what would your view be? Having developers make everything proprietary so that the world's computing infrastructure would collapse? I find very doubtful your claim that corporations are "gamifying" or exploiting software developers in any way. It is fallacious to label corporations as inherently trying to steal from developers, or the developers as suckers. Rather, open source allows for the symbiosis of the two that creates billions in added value for everybody. Nobody loses.
If I buy a stock, does the price at which I agreed to buy it become the new share price on the stock exchange?

Every article on "Where do stock prices come from?" seems to just talk at a high level about supply and demand.

But where does the price come from at a nitty-gritty level? Is it an average of all existing offers or something?

Do different exchanges and stock-ticker websites have different formula for calculating share price?

If a very low-volume stock is listed at $4, and then I offer to buy a share for $100, does the NYSE suddenly start listing its price at $100?
"I can’t explain what is going on here from the technical side, but I assume the shader got converted incorrectly from the source platform (possibly Wii U)."

The consensus from Steam forum posts is that the Director's Cut version is littered with downgrades throughout: missing gold filter, lower res textures in places, lighting differences, etc. Also there are many patched-out bugs that had regressions with the Director's Cut.

It's still a great game, and I applaud the author's efforts to restore it. I'd wager that the effort to bring this version of the game from Wii U back to PC was a merge from hell and too many things just got looked over.
I also deeply miss the times when people had their "sites", which had more personality/memorability than a twitter/instagram feed.
Maybe the time for "personal web spaces" is past and the web will remain " short form content scattered around other people's platforms", or maybe those platforms are popular just because of the network effect?

I've been toying with ideas to bring "social" aspects into sites, as I think the most difficult component, these days, is discoverability (finding a twitter profile is a lot easier than finding a random wordpress blog) and recurrence (nobody uses RSS anymore, for instance, so how do you even know about new content to come back to?).

Or maybe we're just nostalgic, and the future is indeed shorter and shorter bits of text and 5-second vertical video.
There’s another reason for postal services to go the proverbial extra mile: they are absolutely in the trust business.
there are some animations that show how fast molecules and proteins go around in a cell, it's basically a bunch of extremely fast collisions and interactions going at random that end up falling into proper configurations. The way Science is taught in molecular biology (as in, visually, with proteins binding to receptors just like if it were fate) is usually completely wrong.
I have avoided yield() and generators like the plague because they're hard to read and I've never seen them used except in examples explaining how they work. Yield feels like recursion - a neat trick for some corner cases but generally unnecessary.
Yeah figured it was like that.

At this point, I can only recommend waiting until apple stores reopen to get a proper diagnostic done.

Best of luck.

Your argument would be valid if the only trait that enabled humans to provide value was their IQ.
At some point the data hits a computer system, and that will be a vulnerability. You can always go back the the scans, but what if the scanners themselves are compromised? You could require a certain sample size to be manually counted and cross-referenced with the scans to be increase confidence, but I'm not sure there's a clear sweet spot, or maybe it's that I think your sweet spot needs some elaboration: Filled out on paper & scanned, sure, but then every digital link from scanning to tabulation and data storage should be designed to specs similar a similar level of security used in other very high security computing environments.
One thing I've struggled with in JavaScript is choosing a more functional or OOP approach in certain situations. I can never tell if I should stick to one or the other. Allonge sounds like it'll really help me figure that out.
A bit of context for non-Princeton readers (commenting with a throwaway because I don't want to dox myself).

You can take the CS major as either a Bachelor's or an Engineering degree. Princeton requires all Bachelor's students to do two semesters of "independent work" their junior year, plus a thesis senior years. Engineering students have to do one semester of independent work, but they have to take additional courses and have more specific requirements. (The CS BSE degree is currently unique in not requiring a thesis.)

For many departments, junior independent work is a 20ish page research paper you write over the course of the semester either as part of a seminar or one-on-one with an advisor, so the CS independent work is intended to be roughly equivalent in terms of rigor. It's my understanding that most CS students work on a significant piece of software with a writeup at the end of the semester—often (but not always) in a semester on a single topic (eg computer vision, digital audio, etc) junior fall, and one-on-one with an advisor (or in a lab) junior spring. BSE students will often do their one semester of independent work senior year, in either form.

It's often pretty daunting staring at these requirements—and a lot of the onus is on you, the student, to figure out what you want to do and initiate it—so this advice seems to me to be aimed at students starting to plan their independent work.

Don't take this as gospel—I'm actually not a CS major, somewhat ironically, though I have many friends who are. Just hope this helps to contextualize Kernighan's advice.
Yes of course being of the HN crowd I’m not impressed by the website. You know, all quebeckers share the passion of complaining about our government ;)
Short answer: there isn't an easy answer. Yet. (Give QC another 50 years).

Proof? Just look at all the replies you got: each one is dozens of pages of complex (imaginary) math, control theory, and statistics.

The hardest part of QC is exactly what you described: how to extract the answer. There is no algorithm, per se. You build the system to solve the problem.

This is why QC is not a general purpose strategy: a quantum computer won't run Ubuntu, but it will be one superfast prime factoring coprocessor, for example (or pathfinder, or root solver). You literally have to build an entire machine to solve just one problem, like factoring.

Look at Shor's algorithm: it has a classical algorithm and then a QC "coprocessor" part (think of that like an FPU looking up a transcendental from a ROM: it appears the FPU is computing sin(), but it is not, it is doing a lookup... just an analogy). The entire QC side is custom built just to do this one task:

https://en.wikipedia.org/wiki/Shor%27s_algorithm

In this example he factors 15 into 5x3, and the QC part requires FFTs and Tensor math. Oy!

Like I said, it will take decades for this to become easier to explain.

For fun, look at the gates we're dealing with, like "square root of not":

One thing that I think should be clarified regarding licensing: On the license page it says "Licenses are $25 during the beta period.". It is not clear if this means either:

1) During the beta period, a lifetime perpetual license is 25$

2) License for the duration of the beta period costs 25$. After that you may or may not need to renew your license.

This looks really interesting, but I think there are others who are hesitant to invest into something that may end up costing ongoing licensing fees that are yet to be determined.
Over-the-top optimisations with Nim (2018)
>Why is the standard of evidence for one different than the other?

Because hacking one voting machine potentially allows one person or a small group of people to alter thousands of votes.

That person (or persons) has no way to alter anyway near that many votes through in person voter fraud. The amount of effort it would take to alter the results of an election through in person voter fraud makes it extremely difficult to pull off--particularly without detection.

Additionally there are downsides to voter id laws. The most troubling is demonstrably lower minority turn out. There are no similar downsides to methods like requiring paper receipts for voting machines.

Basically the cost benefit analysis is in favor of hardening electronic voting, but not in favor of voter id laws.
The standard has nothing to do with whether the exploit has been used but whether it is possible. There is no credibly attack an adversary could carry out against the election by exploiting the lack a of voter ID requirement. There are however many proof of concept attacks performed against voting machines every time they are introduced.

As someone who hasn’t done much JavaScript since AngularJS in 2014/2015, what is the current state of JS like?

I see there’s Angular (not AngularJS that I worked with), React, and some other frameworks. I see there are all kinds of bundlers and plug ins for these things.

When I was doing AngularJS, I’d just link to a few dependencies manually from a CDN. Looks like now there’s a bunch more complexity and package management for front end dependencies.

It feels like FAR more complexity, but I’m not sure what has been gained. I also don’t know that much, so would love to learn perspectives here from people actively developing in this space.

It takes years for people who have died or moved out of state to be removed from the voter list, you could use those names without much concern
Thanks so much for your suggestion regarding the website!I am thinking about the same thing as well. Will keep improving the site along the way. Really appreciate it.

As to the data for throughput, there are some PoC projects going on and according to data from production, for inserting, one of our clients has inserted 300b records to 6 servers within 20 hours, that is 690k inserts/sec/server.

We want the benchmark data to be verified by decent clients in their production environment. And will reveal more data in the future.

Thanks again!
It’s not dissimilar to a commodity like Gold with some extra parameters like number of stocks.
Comes down to an open market and buy/sell demand.
There are other parts to your example such as depth of order book (orders on the buy sell side) which provide liquidity.
So if a low volume stock is at $4 and you offer to buy at $100 you would probably end up with 100/4=25 shares. If was more illiquid you could possibly move the price up depending on order quantity.
How to Name Startups
Have you considered the possibility that momentum carries forward for a bit like Wile E. Coyote running off a cliff and hanging in the air for a moment before plunging? If consumers can't afford to spend then why advertise, why buy a new smartphone?
Controlling My a/C with a Gameboy
I'm not sure we'll specifically know the answer there for a while, but I haven't seen much in terms of regional variation that seems especially crazy. Most of the places where it's been especially bad are places you'd expect a virus to spread well - major cities with lots of international travelers and high density. Then you overlay the timelines for when various places took serious measures and you get some logic behind why Chicago is doing better than NYC right now.

There's probably a lot of other factors that feed into it - median age, pollution, weather/temperature, potentially genetic/ethnic factors... Even things like the prevalence and use of public transit. It's a lot harder to get/spread the virus in LA where most people drive private cars to everything than in NYC where a lot of people spend an hour or more every day in crowded subway trains/stations.

Working out exactly what contributed to the real-world outcomes we're seeing is something we'll probably only be able to guess at, but nothing I've seen so far feels inexplicable.

Immersive sims and open world RPGs are not the same thing at all. Immersive sims date all the way back to Ultima Underworld in 1992. They share some similar things to open world RPGs, but are distinct things.
Why Are There So Many Data Centers in Iowa? (2015)
Yes, 10,000. iSH is also distributed as an IPA that you can sign and install.
The distance is part of the proof, but not really part of the mystery.

I'm going to throw out an analogy that gets at what's observed and why it's surprising, but doesn't relate to the physics of spin, momentum, position or anything that's actually under observation in these experiments.

It's as if we have a pair of dice, and I throw my die and you throw your die many times. In a classical world, if I throw a three, it has no influence on what you throw; you're equally likely to throw 1-6. But in the quantum world it's as if when I throw a one, your die still has the expected uniform distribution, but when I happen to throw a three, you're a little bit more likely to throw a three. Your die is fair if I happen to roll a one, but it's weighted if I happen to throw a three.

Back in the real world, this is the strange behavior that is observed in experiment. Schroedinger's equation predicts the probabilities perfectly. But Bell shows that it's far from intuitive.
What’s the big deal if it’s a few extra hours/ overnight to get the result?
The medium is the message and the medium is trite, curt, and designed to maximize attention.
I honestly recommend the following:
1. Pick up the standard textbook by Nielsen and Chuang, Quantum computation and quantum information. read the first two to three chapters.
2. Solve the exercises for the Q# programming language.

John Taylor Gatto: Weapons of Mass Instruction
Even assuming 1 person could make it through 10-20 precincts per day, you're going to need thousands of attackers to change even a close national election.

Coordination on that scale is completely impossible to pull off without detection. This just isn't a feasible attack.
Is this a fancy version of the horribly named “digital single vision” lenses that you can buy? Zeiss has a product called “i.Scription.”
Twitter's competitor Weibo launched a feature called "Long Weibo" years ago. It's essentially a blog service, except that Weibo would display the first 140 characters of a long post as if it is a tweet, and a reader needs to click on an icon to expand the tweet into a full article. It's a really nice feature. Clean time line as before, users who hate changes won't get bothered, but those who crave for longer writings get blogs for free. Better yet, an author gets to publish her thoughts in a single place and to engage readers as usual.

Why Twitter doesn't at least try this feature in an opt-in way beats me.

Turn it around, does it seem reasonable that an overseas government should be able to force a US company to make changes to their OS and add functionality it was never designed to have?

If Germany really needed it, they could take Apple to court.

I am sure Siemens would be horrified it it was turned around and the US govt started demanding they modify their industrial controllers, famously targeted by stuxnet, to allow them to be tracked more easily.

Great digging! Thanks so much for paying attention to the benchmark report data. We apologize that you have to wait for so long!

Yes we have been working on the benchmark data for quite some time because we have been working with our clients to verify our capability. For example, one of our clients has inserted 300b records to 6 servers within 20 hours, then we are confident to say that Nebula Graph can manage 690k inserts/sec/server.

We will keep working and provide a trustworthy benchmark report for you as soon as we can.

Thanks again!
The codes are 16 byte (ie 128 bit) numbers that are cryptographically derived from your daily tracing key. Of course all use of Bluetooth will reveal your MAC address, but this privacy concern already existed and is why many devices now rotate a randomly generated MAC address periodically.

I’m sorry but you used so many big words so close together, I could find no purchase with the things I know. Perhaps you could tell me what was the problem that Lie groups are supposed to solve. I read something about an infinitely symmetric transformation- the rotation of a circle is a Lie group. But then what are all the letters about- the A,B,C etc all the way up to E 8. And why did it take 77 hours on the Sage supercomputer to solve E8.
I took a look at the prices of some of the items in the Chapwood index...

They claim the price of a gallon of milk in 2011 is $3.50. The USDA has the current simple average price of a gallon of milk at $3.54 as of April 1st in 2020.

https://www.ams.usda.gov/sites/default/files/media/RetailMil...

The rest are not standardized items, so it is a bit difficult to find data, but the discrepancy in milk prices makes me suspicious of this dataset. Is the claim that all government departments are manipulating data?

I have had to learn nearly a dozen languages in my career. You are on a useful track coupling your study with a side project. I found carefully reading a language manual cover to cover while trying to see how to complete a project was powerful and surprisingly easy. The best manual includes a little example material with the specs. It does depend some on how different the philosophies are. The more different they are the more a tutorial is useful.
I disagree. Headless code on a single server can still be very difficult. For instance, nginx, mariadb, etc, which allow the frontend to function well, are difficult to write. You have to deal with multiple threads, search algorithms, handling tcp/udp requests, and optimizing all of that so it isn't dead slow. Whereas writing GUI in JS/React involves less "computer science" complexity and more compatibility complexity-dealing with things like, what is the screen-size, the locale, etc.

On the note of the HN's perceived hatred of JS, I think its because Javascript has tried to do too many things. Despite its quirks I like Javascript in the context of the web browser, but what I dislike it that it exists in applications and on the server side. The Atom editor should not take up 200 MB and take forever to boot. But it does because instead of taking the time (like sublime text) to write a rockstar system code, they instead used electron. The feeling I get sometimes is that JS developers want to program the same way they do in the browser, everywhere.

My experience w/ twitter has been diametrically opposite - the fact that ideas represented are easily digestible ideas (especially from fields I wouldn't bother about otherwise) have usually driven me towards exploring it further if it piques my interests.

Ofcourse, its about how you're interpreting this information - by inquiry or face value (which can be dangerous).

I was skeptical about feed quality getting diluted when twitter increased character limit to 280 -- fortunately, for me, it hasn't (as much as I expected) with few exceptions.

At the MIL-SPEC level? $840/page sounds like a bargain. This entity is the polar opposite of "move fast and break things".

It's more like, we're going to bury this in a cavern, and when we dig it up in 100 years, it absolutely, positively has to work.
>>Participants who successfully complete a set of qualification challenges on cybersecurity and space this spring will be invited to the ultimate challenge: to (ethically) hack a satellite.

Lol. That is so military public affairs. You are allowed to hack a satellite after being vetted and approved by government. Are Canadians allowed to participate? How about Russians? What about crypto-anarchists who will never pass a military-type background check? I cannot think of a less hacker-friendly competition.

How about this: Just launch the damn satellite. Tell us which rocket it is on (I assume it is a ride share) and give 100k to the first team that manages to broadcast a rickroll.

Bonus round: An extra 100k for any team that leverages the sat to listen in to the spysat network, the one operating on 60 GHz so that it cannot be heard from the ground directly. (Fyi, if you want to meet some men in black, try putting some 60GHz capability on your cubesat. They no like anything that might jam that spectrum.)

Or is the ad informing him he can buy access to a spirit that will accompany him on his self selected journey and help his own desires and achieve his goals?

The anti-ad argument is that he shouldn't have to buy this spirit. If Nike ads were replaced by a non-commercial alternative, then the boy could have that spirit without needing to spend the extra money on fancy shoes.
