Hey HN! Grammar Grizzly (http://grammargrizzly.com) is a website that helps Spanish language learners, make sense of and simplify learning grammar by showing you what and when you need to learn or revise a grammar point with endless examples and explanations.

Learning a language takes a lot of time, effort and strategy, while also being pretty expensive. Most online resources focus on vocabulary and help you pick up a few sentences for particular situations. Which feels good when you first apply it, but leaves gaps in your grammar knowledge which are a pain to find and fill down the road.

We help you prevent those gaps in the first place, learn new grammar and also continuously review known grammar.

Key benefits:

* The grammar points introduced are accompanied by multiple example sentences that reinforce what you have previously learned. With almost endless examples.

* Each grammar point also includes links to other great free online resources to further your studies and cement what you have learned into memory.

* You also have the ability to review the grammar you have learned using a built-in SRS system. SRS stands for spaces out repetition system, that helps you review the grammar when you would have almost ‘forgotten’ it. An efficient and effective way to memorize things.

* The SRS system requires manual input to test your true understanding of the material.

* Start your grammar studies and track your study progress as you cover all of the grammar points from beginner to advanced. Currently there are only a few levels on the site but we will be adding several levels each week.

We are pretty early and are adding new grammar points, levels and features daily, so any us hard feedback you have on ways to improve would be greatly appreciated. Please drop us a line hackers@grammargrizzly.com

It is completely free to sign up and try, so why not take it for a test drive? You can learn more at [grammargrizzly.com](http://grammargrizzly.com/)

There is more to quality of life than income. Despite rising incomes, younger peopple lagging far behind in terms of wealth accumulation[1]

This may have something to do with the fact that the cost of housing has risen drastically as compared to median income over the past few decades[2]

While the cost of education has also more than doubled for men, and increased by 20% for women relative to median income (despite a 73% increase in median income for women) since the 70's[3]

Yes income is increasing, but the costs for the markers of a middle-class existence are increasing much faster.

The problem with that is, the video can only be watched at it's true raw form. Any edits will need to be re-signed with "Edited by X". Now, X has to be trusted and not compromised (by money, bias or hacks).

If X is CNN, then half the population will not believe it. If X is Fox, the other half won't believe. Bottomline, the world will be truly living in virtual alternative universes and it doesn't even matter what truth is as long as everyone in that world believe that.
Same boat here. More often than not DDG has substantially more useful results than Google does.

Sometimes Google is better though, especially when I'm looking for something specific (an article I know I read or a video I know I watched, etc)
It seems Google is running their nightly pipelines with additional profile generation, but sounds like that's restricted to their internal Chrome (not Chromium) pipelines.

Microsoft would have to do their own setup. Hopefully they do.
I agree, somewhat. While the results are clearly worse my feeling is that they are covering more of my use cases as time passes. The really cool thing (and a trick Google themselves used in the beginning) is that a Google search is only a !g away, so I can easily have it as my default search engine.

Why would they not wear masks?

The amount of infected people is so low it’s basically impossible to scientifically test infections, that’s not what they are doing (especially given they tested everyone in advance). They are testing crowd movement, how many people do you get close to etcetera.

> If someone has a better explanation of why subtracting relatively prime numbers repeatedly will always result in one

I'm not sure about better, but I think I can explain it more simply.

Our subtraction is "a - b = c", where "a" and "b" have no factors in common. And the result is that "c" also has no factors in common with "b". Well, what if they did? What would it look like if "b" and "c" had a common factor?

Let's use the example of "b = 6", that was used in the article. 6 has two factors: 2 and 3, so let's see what happens if 2 is a factor of the resulting "c":

a - b = c
----------
8 - 6 = 2
10 - 6 = 4
12 - 6 = 6
14 - 6 = 8

You can see what values of "a" are required to get a factor of "2" as the result, and at this point, I reckon most folk can see the flaw in this cunning plan. But let's rub the point in with 3:

a - b = c
----------
9 - 6 = 3
12 - 6 = 6
15 - 6 = 9
18 - 6 = 12

Again, you can see the result. In order for "b" to have a common factor with "c", "a" has to be some multiple more of that common factor.

(slightly more mathy: we're looking at "a = b + c", where b = px and c = qx (x is the common factor), so we have "a = px + qx" yet we're claiming that "x" is not a factor of "a")

Anyway, since we're subtracting and always get a smaller number, and it's always a relative prime, we clearly must end up with 1.
Is there any other PDF reader on Linux that supports booklet printing?
I install adobe reader for that sole purpose.

Heck that could even be integrated into the system print dialog so the application doesn’t even matter.
How can you tell a true copy from a false copy? What makes one recording more true than the other, if you can only compare it against a reality which no longer exists (because it's in the past)?
It has become a buzzword. Sprinkle it in your text (along with "experiences", "embrace", "diverse", "engagement" etc.) and your text will be hard to argue against. Words are weapons. Just like you have to sprinkle "democracy" and "peace" in statements when you start wars as a country.
Same in Taiwan, you can basically do everything at 7/11.

You're looking for a proof of Bezout's identity, or something in the spirit of that theorem :) to be honest, I haven't seen a proof of it that I "really really like", although you might find one
Anyone else find it mildly(/extremely) distressing that a large part of our industry is dedicated to creating technology that provides little-to-no value to society, but creates enormous opportunities for great societal damage?

We then release the tech to the wild without any proposed way to address the problems, instead saying “the problems this causes are outside the domain of CS, so I won’t bother considering them – besides, if I didn’t create these problems someone else would have”
> Really? In the 1970's in the US it was possible to own a house and support a family of 4 on a single income in the manufacturing sector. It was also possible to work your way through college and exit with a degree and no debt, in a job market which made that worth it.m

This is more of a feature of the transition from a Bretton Woods/Treasury/politics-based monetary policy to neoliberal/central bank/finance-based one no? At 10% inflation, the creditors just ate most of your mortgage debt regardless of whether you worked in manufacturing or not.
Look at how that Minnesota randomized trial measured symptoms in mild Covid patients--it didn't comprehensively measure discomfort at all, and questionnaires were noisy data sources. The Spanish trial referenced took too long to give people hydroxychloroquine.

Most buyside joints don't have anything resembling a security engineer. If they actually need one, it's closer to a front office role than not. You also don't want some random jabroni in charge of something mission critical like that.
For what, exercising the "at-will employment" clause that's in most non-contractor employment contracts? You could no more sue them at that point than they could sue an employee for not giving two-weeks notice. Please don't spread misinformation.
Google searches also often yield Russian sites for me, mostly what appears to be StackOverflow translations.

Seems 80 for sure has it for X11. It's less about UI performance and more about battery life and heat; I might consider installing a Linux distro on my laptop now, last time I did the poor thing ramped up like it was rendering a video project or something anytime I pulled up a YouTube video.
Why didn't FedEx, UPS, and USPS cut/drop prices in order to be competitive? They raise rates yearly like inflation but... shouldn't their costs be going down year over year as they grow larger and larger? Volume discounts, efficiency gains.

I don't have data in front of me so I'm sort of pulling numbers out of my a if you will but I'm pretty sure UPS + FedEx raise rates about 7% year over year for all sizable shippers at pretty much the same time of the year. Meaning, FedEx raises rates, the next week, UPS raises rates.

Which is exactly what I said it was, and not consistent with your framing of departure as a "perfectly logical thing to do".

I'm happy we agree.
What is the workload like at HFT companies? My acquaintances who have worked for them all dropped out because they were working 70 hour weeks, so hourly after-tax, they were actually doing worse than what they would make at a FANG. None of them are super-geniuses though, so I'm wondering if the ones who stay have more reasonable work hours.
Surveillance != Mass Surveillance. If you need to have an investigator show up in person to carry away a thumb drive of data about one case then this means you need to make a cost-benefit analysis about when to send out that investigator. If you can just go dragnet fishing and hoard data forever then there's no incentive to ask whether you really need to.
You can sue anyone, for any thing, at any time. Doesn't mean you have a real chance.
> bargaining should be between users and developers

i.e. the power dynamic should be flipped so that developers have more leverage. This is the core issue. Users have little power on their own and are largely unorganized. So software that's useful to users enables developers to get away with many many abuses before large swaths of users abandon the product. Right now Apple has an extreme amount of leverage over developers and is rich enough to not even notice if they lose even large companies as publishers.

So yes, Apple has been protecting their business model, but the secondary effect is that user's have been benefiting hugely from this since Apple makes more money when users are happy.
I stated explicitly that they are in my comment.

Wouldn’t the second lever you can pull be your relationships? E.g. a close friend of mine works as a VP of Sales for EdTech startups. He knows every person to talk to at every school board. As long as the product is good he can (and does) bring in millions of dollars in deals with some phone calls and plane trips.

I can see what you mean by the tech leverage, but in my experience unless you’re employee number is less than 10 or greater than 100,000 you don’t really get rewarded or have the power to get rewarded from engineering changes. I’ve made changes that increased the bottom line directly by $100k+ a month but still only get a 3% raise unless I have a competing offer. I think the real trick is striking off as a consultant who charges based on results in that situation.
My main issue with CORS is the latency doubling introduced by preflight requests. I wish there was a more secure escape hatch for that than including things like access tokens in the query parameters[0].

Would you agree that your usage pattern of the device is very atypical? I suspect (no hard evidence) tat 99% of Kindle purchasers use them primarily to read Amazon Kindle books.
This capability is why I've always regarded ZFS as great for people who buy drives by the dozen, but a fairly poor choice for consumers and hobbyists. The ability to rebalance a btrfs array and switch to and from any of the RAID modes makes it vastly easier to cobble together useful redundancy from miscellaneous drives, or to recover from a drive failure without having to immediately go out and buy a suitably large replacement drive. If btrfs RAID5/6 hadn't taken so long to get to the current barely-usable-with-caveats state, I doubt ZFS could have caught on among home Linux users.
There's also Kindle competitors, like the Kobo. You can also bet that if this becomes a wide-spread concern, another e-ink reader may come to market that offers privacy and security, maybe some sort of open-source, secure-by-default, ereader. Some attempts at this have already been made [1], but its not clear how strong the market demand for that is and if it will be successful. If you really want a privacy-centered reading experience, the easiest way to do this is just borrow the printed book from your local library.

Yes, this document does not tell how and when exactly it works. I took an Apple Watch and tested it myself before writing this.

Even if you trust that Apple does not use it for anything else, you cannot check this (no source code) and you cannot be sure that they won’t start using it in the future.

Opt-out tracking is not ethical. It should be opt-in.

I always figured that was because WW2 destroyed Europe, Russia and Japan, forcing the entire world to buy from us for 30 years. I don't think it's anything that can be replicated.
I looked at the CDC's page (https://www.cdc.gov/ncbddd/fasd/alcohol-use.html). It contains a number of very negative effects from drinking alcohol while pregnant. But because the context was birth defects caused by radiation, I was thinking more in terms of visible deformities - which can be caused by radiation, but which are much less significant from alcohol.

Perhaps I was being too limited in my concept of "birth defects" - including for radiation. If the radiation while pregnant (or before) gives the child cancer at five, is that a "birth defect"? Maybe not, in the way I was thinking, but I can see how it might be thought of that way.

I think none of those is the best way to write this. Start with the conditional first, so the reader knows a branch is coming. Then have the most common case immediately following. Invert the conditional if that's necessary to put the common case first. Restating the opposite of the conditional can make it even clearer.

"If you are age 59 or under, fill form 331. If you are 60 or over, fill form 445."
They technically gain some with the niche over other options but certainly not the lion's share as they are very commoditized and not the bottleneck of scarcity at all. Shippers and retailers make more and it is far more expensive for them to get into it than to run their own local banana farm. Credit is also less accessible.

Low capital banana growers would do far worse if they tried to compete by growing grain crops in the region as they have to contend with high capital mechanized and chemical using operations with massively better yield and closer markets.

Specialization is at least a local maximia to them even if there are other options better in the long term. Take say West Virgina's coal mining vs a more diversified industry.
At least in the US, phone prices used to be subsidized by the carrier, who passed on the cost as higher monthly prices. The industry almost completely moved away from that now. Verizon, for example, was never buying iPhones from Apple for $200.
I think neither the basic idea of register renaming nor solutions to do it in a way that speeds up the processor (conceptually, each register reference has to go through a logical register-physical register lookup) are so obvious that they are guaranteed to be unworthy of patenting.

If Intel had a patent on this, it must have been on some (possibly tiny) variation, though, as IBM had register renaming in hardware in 1967 (See https://en.wikipedia.org/wiki/Tomasulo_algorithm) and the POWER1 had it in 1990.

How I made a 6-foot tall Clippy
Maybe. I grossed around $300K at a JS competitor, but quit after a few years. These can be unpleasant places to work. High concentration of jerks. Highly secretive, which means it can be hard to find useful things to do. And they're rolling in dough, which means that there's very little motivation to do things right or care about retention.

On top of that, cost-of-living in NY is very high, taxes on high salaries are very high, and it makes you a target (e.g., divorce, lawsuits, etc.).

And as a final cherry, you'd be using OCaml all day, which while interesting, is a language you'll never see again in your career.

I wouldn't beat myself up about it.
Angular Language Service for Visual Studio
It seems one of the final missing links to fully open source hardware WiFi would be the RF transceiver chip. This is, to my understanding, something similar to a high-bandwidth DAC and ADC coupled with configurable frequency mixers to access radio frequencies.

Is anyone trying to create an open source version of that chip? I understand there's not a lot in the way of open source analog chip designs out there, but with Google/Skywater's free PDK, the time may be ripe to change that.

Also, there are many SDR LTE base stations, but can we make our own SDR LTE handset as well? Can it connect to an existing cell network?
