This topic comes up every now and then. I thought this post was particularly insightful,

"One thing to keep in mind when looking at GNU programs is that they're often intentionally written in an odd style to remove all questions of Unix copyright infringement at the time that they were written.

The long-standing advice when writing GNU utilities used to be that if the program you were replacing was optimized for minimizing CPU use, write yours to minimize memory use, or vice-versa. Or in this case, if the program was optimized for simplicity, optimize for throughput.

It would have been very easy for the nascent GNU project to unintentionally produce a line-by-line equivalent of BSD yes.c, which would have potentially landed them in the 80/90s equivalent of the Google v.s. Oracle case."

> have the negative affect of giving us "too much" choice, and so people never settle or make choices, or take chances.

As someone who settled and is now regretting it during the divorce, I have to ask why you think people should settle? For that matter, I'm not keen to even hook up, much less get in a LTR again soon, so I have to ask also why you think people should take chances or have to "make choices"? Life is short; too short to waste on people you obviously aren't "meant to be" with. Why not apply an aggressive filter from the start and save everyone time and heartbreak?

Ask HN: Not getting Jobs, Should I switch Technology?
I am very good developer in my technology. For Past 2 months I am trying to switch the Jobs but I am not getting enough Calls from recuiters. The market of my current technology seems to stagnant.

Most of my company friends working in frontend are able to switch in good companies and easily. Should I start learning frontend my own. I have no production experience in the frontend. But I know some of JS and react.

Should I start looking job in my current technology or start leaning frontend technologies? I am very depressed for the same reason. Please give some advice

Thanks

Cantor showed that these sets have the same cardinality. You can represent a complex (in the form of two reals) by interleaving digits or using a space-filling curve for example.

But this (set) isomorphism between R and C is not continuous. Indeed one can show that there exists no continuous epimorphism f: R^n -> R^m, where m > n, since for every such continuous map f the image f(R^n) has a measure of 0 with respect to the Borel measure in R^m.

I dont know if this an elephant in the room. I'm guessing engineers have thought about this and just not discussed it publicly. They have some pretty smart guys.

Also to nitpick, from "the ends of a viable hyperloop track will have to move hundreds of meters" - this doesn't have to be true. There can be absorption points along the track. Overlaps. Or maybe they tunnel the entire way where its cooler. Or wrap the tunnel in something cooling and reflective. We dont have train tracks moving hundreds of meters do we? I dont profess to know the solution, but do know there are solutions somewhere.

NEOGEO: A Visual History
The proof is: Trump is in charge of the government that is handling relief. Responsibility is his by definition.

In the past, we understood and celebrated the fact that the man at the top was the final word on this sort of thing: https://www.trumanlibrary.org/buckstop.htm

Puerto Rico is a bit different because there's no sovereign state government with local responsibility. In a state, the Feds can help out, but the state government is a separate entity with jurisdiction and responsibility for most of what's going on. In a territory, the federal government is all there is. There is a territorial government, but that is just a part of the federal government.

But it's not very different. If people blamed Obama for FEMA's failures while he was in office, that would be completely justified. The main difference I'm harping on here is that Trump and his defenders insist on deflecting the blame and saying "it's not my fault." When Obama responded to a natural disaster, did he ever say he was doing a great job and all the problems were due to corrupt local officials and crippling debt? I don't recall that ever coming from him, or from any other President from either party.

That would depend on the perspective of the follower. In general, each successive religion sees itself as a continuation of the former, but the former does not see its successor as legitimate.

Meaning, if you asked a Christian whether he and a Jewish follow believe in the same god, he would say yes. The Jew would probably say No (I once heard a Jewish man refer to the New Testament as "that appendix").

By the same token, a Muslim would insist that he follows the same god of Abraham, Moses, Jesus, etc. A Christian, however, would say that he does not.

My experience has been that if people detect even a hint of eccentric or crackpot about you, they hospitalize you at worst, shun you on average, and condescend to you like an invalid at best.

I am diagnosed with severe depression recently. I am also an ADHD.

Depression is a disease and I never dealt with it until now.

I seek help from a good psychiatrist. And he has given me some great advice to fight depression and anxiety.

1. Exercise: I am running 3Kms daily. And its helping me alot. I feel fresh. I feel the strength in the body. The Dr. said to me that if your body is strong, your mind will be strong too. And it will help you distract yourself from depressive thoughts.

2. Healthy Meals: Cut sugar. Cut soft-drinks. Eat fish, vegetables, do proper breakfast.

Incidentally, in Bitcoin, large mining pools do not have control over the consensus rules. It doesn't matter what the miners say, their chain is worthless if people refuse to run it.

In Bitcoin, the economic majority decides what is Bitcoin. And when there's a substantial disagreement (e.g. BCC) there's a fork.

Large mining pools have no more power to enforce consensus rule changes on others than anybody else does.

I 100% do not mean to point this at you in particular. I do not know your situation. But, in a general sense, a lot of the reason for the pressure is because these thing take time. There is no magic cure.

Going to a mental health professional requires time to see results. It also requires being with the right person. Medication won't instantly make you feel better (for longer than the short term), it requires the correct dosage, correct type, etc. The "working out, eating right, plenty of sleep" method may show results but it also takes a lot of time and persistence to see those results.

I am not saying that any of these solutions will work for everyone. I am just saying that any of these solutions takes trial and error. Some people go see a therapist once, don't make a connection, and declare that it doesn't work for them. It will take time. It is a process. Again, everyone is different and need to find what works for them, but whatever it is, they need to stick with it. I know it can be overbearing, but it comes from a place of compassion and concern. No one who cares about you wants to see you depressed. How would you prefer that they approach it?

The questions are core to their matching algorithm. Yes, you'll get superficially better results by being white, tall and having a chiseled face or being a blond, thin and short woman, but that doesn't change the fact that you'll meet lots of girls/guys that you might or might not match with.
On Hulu, I've seen many BofA ads that target my family's racial demographic. I assumed not everyone was seeing these ads, and that BofA was doing the same thing Toyota did here.

It's interesting to see how Toyota is potentially seen as engaging in stereotyping (in a negative way) here. All marketing involves stereotypes, to some extent.

I was also surprised to see how the NYTimes characterized the recent Dove ad in this article. They make it seem like there was a linear progression from a dark-skinned woman to a white woman, but it was actually a loop involving three women (the white woman turned into an Asian woman, who turned into the dark-skinned woman, to complete the loop). And the dark-skinned woman has specifically said that she disagrees with the sentiment that she was somehow victimized by the ad. [1] But to hear the NYTimes tell it, the ad was a simple transition from blackness to whiteness.

I always get tempted to switch to Ruby * whenever i remember that Matz intended to make programmers happy. However, I don't think i'd feel comfortable with a language that only allows object-oriented programming, and moreover OOP of the old way (a method must be tied to only one object. This is what prevents me from going to Smalltalk, btw.)

Additionally, the MRI is perhaps the slowest implementation of a dynamic language out there (besides "R"). I know there are alternative implementations; is there any implementation that is significantly faster (at least as fast as Google V8 for ECMAScript) and that supports the full Ruby language without compatibility issues?

* in place of Python
Optimization makes a huge difference with arrays in Swift. The following took 2.37 seconds (!) on my machine un-optimized:

var bytes = [UInt8](count: 16_737_732, reapeatedValue: 0)

This was slow enough to block my UI (spinning pizza) -- so I ran it on a background thead!. Turn on optimization and it took a more reasonable 0.0165 seconds. BTW, took C's memset only 0.00827 seconds on the same machine.

I switched back to my beloved Objective-C for the app I was developing. Won't be using Swift for low-level image processing.
No. The paper gets this badly wrong. It looks only at the incremental thermal expansion between pylons, and neglects the fact that in a sealed tube the thermal expansion will be cumulative.

"These would absorb the small length changes between pylons due to thermal changes, as well as long form subtle height changes." [emphasis added]

The cumulative expansion is dealt with in a single sentence:

"A telescoping tube, similar to the boxy ones used to access airplanes at airports would be needed at the end stations to address the cumulative length change of the tube."

But that's not enough. The entire track near the ends is moving by this amount. That means that the ends of the track are advancing and retreating over multiple pylons (unless you can figure out a way to cantilever the track over 300 meters). This is a completely unsolved problem.
I would guess that Bitcoin is only a tiny fraction of the capital flight from China. I could imagine a few scenarios where China's access to Bitcoin gets cut off somehow, tanking Bitcoin, but leaving the other more utilized capital flight methods intact.

That's a shame, since one's understanding of so much of Western art of all sorts is greatly improved by familiarity with: 1) the Bible, and 2) a dozen or so Greek and Roman authors, including and especially Homer. By losing that foundation one engages with pretty much the entire body of Western art at a huge disadvantage. It's a kind of common language of symbols, tropes, and allusions that bind the whole thing together, without which much is lost.

Because this issue has been brought up many, many times since the Hyperloop paper was first published and no one has yet proposed a viable solution.

But you can't curve the track. The track has to be very nearly straight or the G forces become intolerable.

This is the thing: lots of people glibly propose what they think is a solution, but none of them actually work.

In either case they are probably detrimental for the team.
