A part of the problem is character entry. If it were easy to enter in all these symbols APL may have taken off and we wouldn't have gotten ASCII variants of it like J. So it's somewhat easier to just take our latin alphabet and turn a single symbol into a pair of letters or a letter with a subscript.

The symbols in math are great for writing by hand, but can become cumbersome when typing.
They didn't fork, RH just rebranded it.
Agreed. This article has some good thoughts but the "White" thing is annoying. There are plenty of white people whose life is not golden. In the end it comes down to wealthy vs not wealthy. Race or gender doesn't matter.

Clearly you dont understand that people with 300 Million dont just put it into the market. That's why the whole Hedge Fund/Private Wealth Management industry exists. This argument is so far from reality.
Look up the definitions of servitude and slavery on a dictionary: they fit.
> capacity to support a self-sustaining tech industry.

You mean the industry that includes tons of companies founded by immigrants or their children?

I'm not saying SV can be replicated elsewhere. But the code you're writing can be, if the price differential is big enough. Outsourcing is a PITA, so if the price differential is not big, why bother. But... if it's big enough, innovative people will find a way to make it work.

> This will close that spigot in favor of either the local talent pool or a foreign talent pool where immigrants find an employer to sponsor their application for permanent citizenship.

Or a foreign office without all the bureaucratic, nativist BS.
My theory is that math anxiety is really anxiety about a cold assessment.

In other subjects you can rationalize to yourself in various ways: the teacher doesn't like me, or I got unlucky and they only asked the history questions I didn't know.

But with math, no rationalization is possible. There's no hope the teacher will go easy on you, or be happy that you got the gist of the solution.

Failure in math is often (but not always) a sign that education has failed in general. Teachers can be lazy or too nice and give good grades in art or history or reading to any student. But when the standardized math test comes around, there's no hiding from it (teacher or student).
Think of the intro to the Ghost in the Shell, where the android body is floating up through a bath, and the manufacturer layer on the body is dissolving and being removed. This method could detect that the material is 100% removed from the body as well as confirm that the body is created exactly to spec.
I don't believe in shareholder primacy, but your first link has no substance at all. Not the best source. And this argument is rather disingenuous, it is codified in law that directors have a duty to act in good faith. This all seems somewhat pedantic.
The fear emotion is really something else.

People fear they are missing out on something - a quick scheme to make money...
What? $250k is a lot of money. I know very very few, if any, people that could just shell out that kind of money in any situation.
It's more complex than that. There is only one racial side here... there is no other side that believes black lives DON'T matter.

Opinions are complex... Philando Castille certainly did not deserve death, although to say his murder is a symptom of epidemic racism is shortsighted and representative of narrow statistical exposure. Cops get away with murdering white people too.

We would be better off preaching color blind unity and stop blaming white people for the inevitable effects of high crime, police-xenophobic neighborhoods. Particularly where demonizing white people is ok. Cops working in those areas have a hard job. You have no idea.

We don't live in 1968 anymore, or even 1988. I realize there are many living today who did go through terrible times. There are also quite a few racists still around. But Black Lives Matter's finger-pointing at innocents is making more racists.

You can't help where you're born. No one likes to be punished for the sins of the father.

You aren't helping.
"There's no arbitrary obligation for a company to pay a "liveable wage", whatever that is."

And I disagree. I believe there is. At the very least, I believe that a company should not be relying on labor subsidized by welfare.
Without a citation, that seems right, in the narrowest sense of "owning single shares in a company".

Keep in mind that "owning stock" isn't well-defined though, that could mean (a) own individual shares (narrowest), (b) owns shares or ETFs (broader), (c) owns mutual funds.

But that still doesn't address my point. It's a lot bigger when both private sector, and public, pensions are included.

This issue is near and dear to my heart because I grew up in Illinois (now living in California) and am watching the budget battle unfold there. They have a huge pension funding gap, and the returns of the stock market are going to have a very direct, real effect on how much tax the state has to collect to fund the pensions.
Which a problem with using linters, not with programming.
> I think math education needs to be reworked from top to bottom to focus more on building blocks. E.g. I'm not sure there's enough focus on what multiplication is before you're expected to memorize the times tables.

This was tried. It was called "New Math". Spectacular failure. Do you want to know what worked? Memorizing times tables.

There's just no way around the fact that drilling is key to early mathematical learning.
Russian Dirt on Clinton? ‘I Love It,’ Donald Trump Jr. Said
As someone who went to university for mathematics (and computer science) I can tell you this is the most common misconception. People think that I spent years studying how to become a calculator.

I love talking about both subjects I went to university for actually and both can be difficult to get people interested in. There are massive misconceptions about both.

Is the European version pretty much the same?
I'm certain you would be confused by non-standard usage of notation. It's not just symbols and that any symbol can be used. Try reading or speaking English with the adjectives in an order that is not expected. It's confusing as hell but grammatically correct. Our brains get trained to see things in a certain way and when the symbols get jumbled up so do we.

(x1(x2+x3) - x1(x2))/x3

is simply not as understandable to a first year calculus student as

(f(x+h) - f(x))/h

I've been teaching university level mathematics for 25 years and I know mixing up symbols confuses people. Try reading Newton's Principia. It's really hard to know what he's talking about.

EDIT: Try this equation. What famous one does it represent?

(sex(sxe) - sex(xes))/(sxe - xes) = xse sex/xse sxe

Really short and accurate answer from People Who Know about why you don't see 'JavaScript' used as often:

- Oracle own the trademark on JavaScript (though buying what was left of Sun, through the Sun Netscape Alliance)

- Nobody trusts Oracle

A good idea proposed is just to call the language itself 'JS' and have it not stand for anything.
That is amazing. I think I've looked at every photogrammetry, desconstruction, hand modeling etc... technique for 3D reconstruction and this one takes the cake for ingenuity, quality and capability.

Not sure how practical it is right now, but I wonder if you could do this with air volume at a high enough delta measurement resolution you might get some amazing results.

I understand what you're getting at but I think you may have misunderstood me. Being able to run a marathon in 3 hours probably meant you set aside a hour or two, 5 times a week for years. Walking a marathon in 7 hours means that your in the sort of shape that is required to not die early from being sedentary.

If you tell me you RAN a marathon, I'll think that you RAN a marathon. If you walked a marathon and you think that's a great accomplishment (and it very well may be), I'm also very happy for you. But it's not the same thing. Conflating the two is dishonest and devalues what others are doing. It's the difference between building a website as a fullstack dev vs building one using Square Space. It's not that there's anything wrong with Square Space, but if you tell me your a software engineer afterwards, I'll think of you the same way I think of marathon walkers who tell me they ran a marathon.
isn't that hideously inefficient? you're making a new object each iteration.
and if you look at half the workforce at these companies,Labor- the ones not making 6 figures- like couriers, personal shoppers, cafeteria workers, content reviewers, helpdesk, customer support, admins, security- they are contractors that don't get 401k, IRA and live hand-to-mouth and always precariously poised to be fired anyday. They can't afford, can't buy and never benefit from stock price increases.
I've got 512gb and it keeps being close to full.

A windows xp, 7 and 10, a few Linux vms, source checkouts for GCC and clang and a few build trees, some traces that end up being a few GB, it all adds up.
Agreed... most space is used on media (including 3D designs, layouts, etc.). Code is just really compact, even when you have a huge local version tree.

The only counter example I can think of are large databases/VMs... which most wouldn't keep local anyway.

Really, with the speed (latency/bandwidth) of modern networks vs rotating media there seems little reason for local storage that isn't flash drive fast... other than security or minimizing bandwidth.
Real-World Angular Series – Part 5: Animation and Template-Driven Forms
Apple got to this point by notoriously never paying out dividends. Paying out dividends obviously takes away money usable for growth. I don't see any competition between these two models. You issue stock to get capital to compete with other behemoths. If not for having contributed cash to the endeavor, the investors function more like parasites that want to extract the maximum they can from the host. Such massive payouts will probably stop Apple from becoming a major conglomerate with varied tech/science/engineering interests in the distant future and limit them to high end consumer electronics. They got to this point by acting more like Google, and they will likely degrade like HP or IBM now.

A very silly article comparing two companies with similar money-management history and acting like some competition exists between the models because investors recently got an upper hand with Apple. They wouldn't have gotten their market position doing this. It strikes me like comparing two athletes when one recently acquired a disability and suggesting that the disability contributed to their historical success and suggests some new model for the sport going forward.
They're here.

When Are You Too Old for an MBA?
I don't know a generic solution, I just can say what I did:

1. I quit my office job.

Worked there for about 7 years. I saved some money and got unemployment benefits (60% of my previous salary) so I had 1 year to do nothing.

2. I did some OSS stuff

OSS teams are almost all remote and they love contributors. So it's not hard to find some and ... well contribute?

It's an easy way to get into a remote team.

I didn't do it for long, because I don't like maintenance dev stuff, which working on Firefox stuff basically is if you a contributor for Mozilla, haha.

3. Do some remote studying

I started a master in computer science at a remote university here in Germany. They had two mandatory programming projects I had to do with a remote team of other students.

We did much coordination via slack, hangouts etc.

This was also a good way to get into the remote workflow.

4. Post your CV online and wait

I saved money for 2 years, so after one year of OSS and remote projects, I posted my CV on some recruiting sites (Angellist, Stackoverflow, etc.) and waited.

Took 3 months till I started my first remote job. Talked to 5-6 companies. Some never called back, some took 2 months to tell me they want/don't want me.

5. Worked remote for 2 years

I worked remote for 2 years in a startup that was about 300km away from me. Went there every 2 months for a day or two. They were rather picky with their remote employees and always tried to persuade me into working in-office. One day they they lost a investor and had to let a few people go, since I was the only remote guy left, I guess they simply wanted to get rid of me, haha. So I got fired.

6. Started freelancing

With >2 years of remote experience and >10 years of general developer experience, I started freelancing.

Got 2 projects. One I found by pure luck online in some project small directory and one in the company where my girlfriend works. Both don't care how and where I work.
I was taught multiplication by rote memorization of the tables. It didn't go well as I'm bad at rote memorization.

People ask me if they see the beauty in math when I'm complaining. I do, but I also see the other kids outside playing while I'm held back from recess until I can tell you what 7*8 equals. Fuck that so much.
interestingly, to keep the profit margin, they are also pushing for SSDs that have even higher per GB cost, e.g. Optane.
Here is an interesting observation on what you wrote:

x(y) = (+/-) sqrt(y)

is not valid notation. On the left hand side you are stating that x is a function of y. But on the right hand side your usage of (+/-) indicates that y can go to two different values. Hence x is not a function of y. To be a function one must have each input going to a distinct output.

Fedora is not identical to RedHat. It's more of a proving ground for new things that may or may not make their way back into RedHat Enterprise Linux.

It's not a simple rebrand. Fedora Core 1 took what was staged for RedHat 10 and packaged it with a different license and sent it off in a different direction.
Another thing this may be useful for is to be able to snapshot and compare a product from version to version, without having to worry about setting up deployments and environments for older versions.

For my money I would much, much rather own shares of stock in my retirement plan than have a state- or corporate-backed pension.

Have you seen the movie Casino? That actually happened, the Teamsters pension fund came under control of the mob.

What about Illinois, which is facing a $120 billion pension shortfall due to decades of accounting gimmicks?

What about the UAW guys, who were counting on pensions from the big 3?

All I'm saying is, look at how it _actually_ works, in practice, vs. how it _could_ work, in theory. The reality is, DB plans are getting phased out because they're too expensive to service, and too risky for employees.

You can make the argument that people aren't getting compensated enough, and maybe that's true, but that's not an argument about DB vs. DC.

The point is, there are no certainties in this world, and if someone tells you there are, they're lying.
The parent comment was talking about H1Bs working for startups. Startups are not InfoSys or Tata. I agree with you and the parent comment, as I said, that H1Bs are widely abused by InfoSys and Tata and I would be very happy to see that abuse stopped -- but let's not tar startups with the same brush!

VC: Hey DHS, Entrepreneur lied about something 2 years ago just before/after he came here.

Entrepreneur: That was not a lie - that was marketing. Every business does it.

DHS: "Get out"

> For a VC and an entrepreneur, the VC has shares in a company that is run by the entrepreneur. The entrepreneur ALSO has shares in the company and always will even if they leave the country.

This is nice in theory, but in practice (especially in knowledge economy companies), the employees are the company - everything else is furniture, coffee machines, ping pong tables...

The VC can just start a new company with ideas stolen from the person they just kicked out. They can offer the (now unemployed) employees of the previous company slightly more equity and money then they would have received at the previous company.

I don't understand why you are defending a system like this.
The data I was going to put on it weren't that valuable, mostly music and phone photos - I wasn't that distraught when I snapped the old SD card. A quick test that it wasn't completely fake would have satisfied me.
> I have never seen an H1B holder make any less than their counterpart born in the US

I have. And based on the patterns I saw in hiring, I expect that it's the same across the industry, even when companies aren't trying to underpay immigrants. It's a fascinating perspective when you get involved with hiring at the offer stage and see the negotiations. You can send the exact same offer to an H1-B and a citizen and the counter-offers will be completely different. A citizen will ask for more comp and an H1-B will ask for an EB2 sponsorship. Both are entirely rational decisions the since employment flexibility of a green card is probably worth more to an immigrant than an immediate increase in comp.

> Best reform idea I've heard...

I still think the best idea is to impose ratios like other countries do. Let companies hire as many immigrants as the like so long as they're also employing, in similar positions, the requisite number of Americans as well. If the theory is that highly-skilled immigrants are bringing skills and knowledge that's in short supply here, we should be trying to have them work with Americans as much as possible so that Americans can learn from them. Companies that abuse the current system end up having nearly all-immigrant work forces. Meanwhile, smaller companies without large legal teams can have difficulty getting even a single H1-B hired. Ratios fix both problems and they also help immigrants assimilate faster because there's less chance they end up working with mostly other immigrants.

Your idea of using salary as the deciding factor is great in theory, but in practice we don't allocate capital wisely. We'd end up with a lot of H1-Bs in finance and almost none in science or any of the many lower-paying areas that require education and intelligence.
> So what? Is scrolling really that big of a deal?

Yes.
> It may be new but it is not a well-thought design. 110+ characters per line is hard to read and ugly

Er, not sure if you're looking at the before and after screenshots the wrong way round? The new design appears to reduce the number of characters per line from ~100 to ~80 (by increasing the body font size).

Compare first line of Array#slice in the old design:

"The slice() method returns a shallow copy of a portion of an array into a new array object selected"

vs the new:

"The slice() method returns a shallow copy of a portion of an array into a new array"

New Intel Xeon Scalable Processors Boost HPC Performance – InsideHPC
On the other hand, if you can make an organization work with a lower grade of employees, you will scale much more easily and cheaply. Maybe its a pipe dream to accomplish this but I think it's probably somewhere in between. At the scale of a multinational corporation with hundreds of thousands of employees, it surely comes into play more.
It's way too early to judge "New Math" to be a failure. I think the idea of focusing on concepts over computation 100% in the right spot. The biggest problem to its acceptance is cultural. Parents don't feel comfortable with math concepts, and in my opinion, most of the negativity is coming from that insecurity. So they demand for things to be taught the "old way", even though that's produced a generation or two of mathphobic Americans.

EDIT: As pointed out, I mistook OPs invocation of New Math to be talking about the much maligned Common Core rethinking of math education. I was briefly a high school math teacher, but before the roll out of these changes, so I can't comment first-hand on what the new curriculum looks like in the actual teaching. But I do know how poorly prepared my students were for math beyond arithmetic. They were trained with similar curriculum that I had experienced growing up in the 90s, which I think is poorly thought out.

Apologies for the confusion caused by me not recognizing the term New Math.
The bold headline steals attention away from the copy; it makes it much harder to focus on the actual content.

IMO they could try making the bold header a lighter shade to stop stealing focus. I much prefer the older one for readability.
