As someone who has been in this industry for a long time and seen a lot, this still baffles me.

Who agrees to being on call 24/7 for a week? Especially when you are getting paid a typical professional salary? It seems absurd. I've always been active after hours and willing to jump in when things happen.

But this idea that you are essentially working (since you need to always be somewhere you can start working within minutes) for a week out of a month every month of your life for a salary job with no equity or long term payoff on the other end, has to be the most bizarre choice a person could make.

Maybe there is something to that I don't understand? I guess if you don't have any other interests or people in your life. But that just seems really sad.

Possibly someone who does this could help me to understand this a little better?
Convolution is essentially polynomial multiplication. That's how I think about it.

You remember (a + b)(c + d) = ac + ad + bc + bd?

Or (2x^2 + 1)(4x^3 + x) can be calculated by doing conv([0,2,0,1], [4,0,1,0]) (the numbers represent the coefficients). The results are the coefficients of the resulting polynomial.

As the polynomials grow larger this gets harder and harder computationally. Convolution theorem lets you use Fourier to you convert this multiplication into a pairwise multiplication so that

fft(f * g) = fft(f) .* fft(g)

where * is convolution and .* is pairwise multiplication.
That doesn't explain the clomifeme. I doubt the drugs are performance enhancers in bridge, but he might have been taking them for other (cosmetic?) reasons.

It's been rock-solid. Only time it hasn't worked for me was when I was on one public wifi that blocked most/all UDP traffic.
There's Go functionality such as pprof that requires the use of the default serve mux and therefore you can't use pprof with a true shared nothing design. The log module is similar.

Does that lead to more bugs in programs? I don't know. It's quite possible it doesn't matter in terms of defect count. It's not shared nothing, though, is all I'm saying.
if your office firewall blocks a site secured with ssl, you will see an error message something like this. Do you have an aggressive firewall? If so, it's probably being blocked. Try from a different connection (like a coffee shop or home) and see what the result is.
From my observation it’s much easier to recruit Java devs than Node devs, for example (I’m located in an average city, not a leading one like SF or NY). I’ve closed my Node projects because it seems to be too early to recruit and train interns in this area.
The only downside of a bidet is that you get so used to the cleanliness that using a restroom with toilet paper will seem primitive and you will feel unclean for the rest of the day. You will also wonder how can it be that everybody else laughs, plays, and generally acts normal while having stuff smeared on their behind.
It's not a trade-off! We as a species absolutely require people to have kids. Discriminating against those who do is the most fundamantally wrong thing I can think of.

It is what we are here for, if nothing else.

It is a good practice for static pages focused on performance (e.g. landing pages like this one) that the critical CSS is inline. It is common that all CSS for above the folder content is inline - usually done through a processor, so the development code is kept sane.

The application and approval process, filtering, certification, authentication, etc. sounds like a separation problem. Since the site is about math, IIRC there's some math for separation problems??

Uh, since the site is for "math/stat" and there have to be rates of false positives, that people are already complaining about, and false negatives, I don't see people complaining about spam, then we're into statistical hypothesis testing, right? Sooo, to do better on the rates of false negatives, we want more data for a more powerful test. Sooo, we need a multi-variate test. Since no way can we justify assuming probability distributions for all the relevant data, we need a distribution-free test. So, where can we find one of those???

Disclosure: This question is just an exercise. For an answer, I published one of those. So, it's an applied probability calculation based on an algebraic group of measure preserving transformations! It may be a rationalization of resampling theory. Crudely the result is obvious, but a proof is tricky. It may be that the work is a stimulation for and or connection with approximate independence, e.g., maybe as in some work of Choquet student M. Talagrand.
It seems obvious that there's room for improving a system that can't detect an object that's 75 feet long and 13 1/2 feet high directly in front of it.

Self-driving cars are decades away from reality, and self-driving trucks are even further away.
How does the rate of accidents while using autopilot compare to manual driving? It seems to be an important question as it can't be expected that automated systems will never get in accidents.
> I wonder how much information, if any, is withheld by military organizations in various countries.

Ooh, I can answer that. All of it, unless forced to disclose by political factors. There is no upside to the military to releasing anything, ever.

HN is a geekfest, and I'm a geek too. I could not, and still cannot, comprehend how resistant to the "helpfulness instinct" a military man is. I, by my very nature, cannot resist helping people whereever i can, and offering whatever information I might judge useful whenever I can. The military [1] is the exact opposite of that. It's hard to get your head around.

I have zero doubt that one or more militaries in the area, especially Singapore, know exactly where MH370 went, or at least what direction it eventually took off in. Every radar in the world is recording 24/7. They have no incentive whatsoever to divulge what they undoubtably know. We'll find out in a few decades, probably.

That one isn't filled with unfiltered optimism :P

Southwest was able to offer such a service because of their long term contracts on oil.
That looks extremely expensive for something you use every day.
Well yes and no. On the actual tax form you just put a total, but TurboTax asks you to break it down, one so that you get it right, and two because if you get audited you have to provide broken down info, so you can't use their audit defense product unless you break it down.
I don't know what led to the decision. The CEO had already built a very successful company on the same principles. The company where I worked had these same principles from day one. This also happened to be a start-up and not a megacorp. This was not in an anglophone country, so norms differ. I am from England for the record. Out of all of the companies where I have worked, this has been the most successful, and became successful the quickest. The IDE was IntelliJ-based.

I have never before or since worked at a company that allowed "every man for himself" while managing to enforce the discipline required to maintain a uniform style guide, tests always passing and code review. It was nice to go over to a colleague's computer and see exactly the same code as I see on my own, and in the same environment. Everyone used the same debugger interface and same unit test interface, because everyone used the same IDE. They become more natural to use. People were able to refactor easily and maintain consistent naming standards, which is more difficult in Emacs, and especially in vim.

> “We opposed the data broker registry in Vermont because we believe it is unnecessary to single out a specific industry (in this case, ‘data brokers,’) when first-party data controllers often have as much data as companies like Acxiom,” the company’s chief data ethics officer Jordan Abbott told Wired.

I agree with him. First parties like Google and Facebook should be subject to the same rules.

But what really surprised me was that Acxiom has a chief data ethics officer. That job sounds like it would be as real as a consumer health advocate at Philip Morris.
Yes I did. Wish you the best.
Again?

So far, Teslas have crashed into two semitrailers, a street sweeper [1], a stalled car partially in the left lane, a stalled truck partially in the left lane, a fire truck, and two road barriers. We don't know about the latest one yet, but in all the other cases, the crash was not preceded by automatic emergency braking.

Tesla lacks basic obstacle detection. The original Mobileye system had "recognize car" as the first step. If it didn't look like a car, it wasn't an obstacle. Tesla claims to have replaced that with their own system, but we're still seeing full-speed collisions with obvious obstacles.

"Saved" China and the world from what?

What problem could justify such an abhorrent intrusion into a person's life?
China is bad. Have I got the gospel right?

Now, the _facts_ are that the policy did have a real, significant impact. And that has benefited mankind as a whole.

But, OK, let's say it was useless... I cannot be said to have been disastrous, then, can it?
> Seems like on-site open-book 90 minute real-world problems would be a nice solution.

It is. And it's superior to a take-home test because you know the candidate wrote the code, you know how long it took them, and you can turn it into a pair-programming exercise.
I second the DFW recommendation.

He wrote a long-essay for Harper's on the experience of traveling on a cruise ship. You can find a free pdf of it doing a google search for "On the (nearly lethal) comforts of a luxury cruise".

I highly recommend that essay.

Look, some misguided individuals seem to hate Chromium because they think it doesn't respect their privacy or out of abject hatred for Google. But a lot are not actually looking from an engineering point of view. Browser's are the 1# security risk on any computer system due their complexity and access to the outside world. Chromium was the first (and mabye only) web browser that was designed from the ground up with privsep in mind. Firefox on the other hand did not have privsep for a long time, it was only implemented later after the fact. Not only that, Chromium now supports unveil, and new security innovation that blocks the browser's access to all files folders on the system except for what specified in settings.
This is a great outline. Martin Kleppmann's Designing Data Intensive Applications [0] is very much in the same domain as what's in these notes.

Speaking about scale and distributed systems: AWS specific resources I find interesting from their EdgeEngineering/NetEng teams (I haven't seen many other service teams in AWS openly share as much about design as them):

- https://aws.amazon.com/blogs/architecture/category/networkin... series of articles on Route53's 100% data-plane availability architecture [1].

- https://www.youtube.com/watch?v=O8xLxNje30M colmmacc [2] (seems to be the eng behind AWS HyperPlane [3][4]?) on 10 design patterns for building resilient systems.

- https://www.youtube.com/watch?v=swQbA4zub20 Peter Vosshall (co-creator of Dynamo [5]) presenting "cell-based" design in-use at AWS.

At my job we use tabs, but elsewhere I've always used spaces. Rather than installing yet another plug-in, I use a Vim autocmd that checks to see whether I'm in a company repo, and if I am, it applies some overrides.

Doesn't matter how long it is if you're pointing the same way.
For easier reading and referencing you could specify the total big-O cost of your algorithm right in the beginning (or even in the abstract). And an indication on which range of input sizes it is likely to outperform karatsuba multiplication before being outperformed by the fft.
Yes, I agree. I was wildly exaggerating.

Life sustaining equipment is regulated and has a lot of resources spent on it to make it reliable. And toy software doesn't matter if it falls down.

I guess medium level services fall in between. Still causing inconvenience and monetary losses when they fail.
I used to think this way. I've stopped.

Now I call people whatever they want me to call them. They've surely thought about it more than I have and with so many problems in the world why would I get bent out of shape over saying "they" instead of "she" for someone that I think looks like a woman. Why bother worrying about bell hooks or Kim Dotcom, it's just a waste of energy. People are different and that's that. Some people think I'm weird for studying weapon systems and arms control.

It takes all types and hooks's book "all about love" changed my life. How can I begrudge her choice?
Hiring people is also about portraying your company in a positive light. Your allusions to the TSA security screen, and how you have to be "trained and calibrated" seem to imply a robotic kind of detachment that would probably be very off-putting to me.

Often employers seem to be of the mind that they have the treasure and it's up to them to filter out the best candidates (sellers market I suppose) regardless of how they appear in the process. I would imagine that a lot of brilliant people get turned off by this. Which (oddly enough) is also fine by me - like dating, I'd rather spend my time finding an open minded/humane place to work, and I find hiring practices are often a rough initial proxy for that.
World population:

I sold my ORCL a couple years ago (had held it for 20 years) for just that reason. A company whose customers use their product because they have to rather than because they want to is doomed.

Hey hey. My name is Michael. So, just did a quick cut&paste of part of your comment that I wish to comment on:
"Luckily, Firefox, arguably among the most 'free from corporate greed' of the browsers, has now finally caught up to Chrome on stability and speed (in my experience),"
No, you're not alone. I will absolutely agree with you about Firefox quickly catching up to Chrome and at an alarming (but satisfying) rate. By that, I only mean that Google is no longer a sort of "underdog" like it was-at least when standing next to Microsoft-(and hasn't been for some time).And I have to agree with Reda's comment that Google has become the very thing that it was trying to stomp out in Microsoft: a sort of monopoly-just-short-enough-of-being-a-monopoly to escape the law's notice. What I fear is that Google will get so big and powerful that if they did get close enough to technically qualifying as being a monopoly that they could and quite possibly would be like, "SO?! WHAT ARE YOU GOING TO DO ABOUT IT?" And being able to because at that point, who COULD do anything? I never thought it possible for any one company until recently. It is too close for comfort.
Thanks,
Michael

ps- sorry it was so long. I actually am working on that.

Clomiphene is indicated for low sperm count in men, it increases production of FSH and LH, which in turn acts on the testicles. That would also explain the exogenous testosterone. Thanks, Guardian, for letting the world know about that person's medical issues.

While gender and biological sex can be disconnected under certain conditions for the majority of the population this is not the case.
Can I just use words to describe it though? Or pseudocode? Short lists of issues that need to be considered in the design, with various options and their pros and cons, in words?

It's the expectation of drawing pictures on a whiteboard that's so strange to me, that's completely alien to the way I think about software. I think in text.
In this case the Tesla hit a truck that was perpendicular to its direction of travel.
If only there we some other way to notice solid objects, instead of relying on the statistical analysis of video frame images relative to one another, over time, in real time.

If only we could figure out how to detect solid objects, but alas, such a difficult problem. So hard to implement that no one should hold their breath, in hopeful anticipation that a carmaker might add solid object detection to their sensor array package, so that cars can do the most important thing everyone expect from them.

But, you know, when you make a self driving car, hazard avoidance and collision detection actually turn up much lower on the list of priorities that you'd expect.

(in driver's ed, we learned not to overdrive our headlights, to not drive so fast that our stopping distance began beyond our visual field of good lighting surrounded by darkness; meaning that should an object suddenly appear in the light cone as you approach it, the combination of your human reaction time, combined with the tire's capacity for friction against the road surface, combined against the total inertia of the car in motion should all remain in the cognitive focus of your situational awareness as you drive a car at night; without this, as a human, you are not a safe driver;

and yet robots are judged according to different standards, even though, for them, it is always nightime, and the world is perpetually a cloudy environment shrouded in mysterious darkness; too bad that's not what sells cars)
I don't see any GCM ciphers nor ECDHE/DHE key exchanges deployed on this site, so forward secrecy and authenticated encryption are not implemented and supported by the Not Quite So Broken toolchain? It would be a project of great value if those are implemented, plain RSA and CBC is pretty much dead in TLS nowadays...
Ah. Bigger than a proverbial barn door then.
And using 8 bits to encode 2 is also a very strange choice.
The settings can be derived from other files in the repo
That's a topic of much debate. Tesla parses the numbers to indicate that it's much better than manual driving, but others are skeptical.

I disagree. Most drugs on the list (maybe even all?) will increase physical performance across the board for all physical activity. Testosterone will bump up muscle production whether you're swimming, running, cycling, lifting, skiing, or whatever.

This is just more evidence that Bridge doesn't belong in the Olympics, IMO.
And the rear of a dry van truck is 8 1/2 feet wide by 13 1/2 feet high, so if it can't detect that, how is it supposed to avoid another car, let alone a pedestrian?

This case (truck perpendicular to travel path) should literally be the easiest test case for object detection, other than larger stationary objects like buildings and bridges.
