The code in question is:

} catch (Exception e) {
if (!((_ok) ? true : (Math.random() > 0.1))) {
return res;
}
(error logging)
_ok = false;
}

A 10% percent chance to skip logging under certain circumstances. Very strange code, and a strange way to write it. Also wouldn't this be equivalent to

if (!_ok || (Math.random() > 0.1))
It has to do with the high voltage and the impact of voltage loss.

† I've accumulated a lot of stuff I'm glossing over at the end.

Let's consider a 1 square millimeter cross section wire. Your power lines will be bigger, but it scales up with the area.

Electricity facts refresher:

ohms measure resistance to electricity movement
amps measure how many electrons per second you are jamming down a wire
volts measure how hard you are jamming the electrons down the wire
watts measure power, this is ultimately what you care about

volts = amps * ohms
watts = amps * volts

this is true for AC and DC

Your copper wire has a resistance of about 17 ohms per kilometer. This wire is allowed to take 3 amps of current when used for power transmission. That makes the voltage drop over a kilometer be 3 * 17, 51 volts.

This voltage drop doesn't depend on the voltage of your power line, just of the current running through it. If you are Mr. Edison with a 110 volt generator, then you have lost almost half of your power just transmitting it one kilometer.

If you are the Pacific DC Intertie sending power from Washington state to Southern California, you are operating at 1000000 volts. You are losing 0.005% of your power per kilometer.

The whole AC/DC thing was because in the early 20th century it was easy to change the voltage of AC power but difficult and expensive to change the voltage of DC power. You could pump AC up to higher voltages for transmission, and bring it back down for domestic use.

␄

† Notes follow:

The current limits I used for the wire are for common electrical engineering work on devices, I don't know the limits for power transmission lines, but…

I sort of doubt they use copper for transmission lines, too expensive, so the resistances will be higher. Wikipedia to the rescue: The Pacific DC Intertie uses aluminum wire, reinforced with steel, with a 644 mm^2 cross section. (Not clear if that is the aluminum of the whole thing.) They are also pushing 3100 amps which puts us in the ballpark, 1000 times the current in 644 times the cross sectional area. They are operating above the power transmission guideline I picked but below the limit for chassis wiring.

Also for transmission lines, the much thicker wires will not be able to dissipate heat as well as the tiny wire I used and there will be a derating of their current capacity from that.

High frequency AC gets weird, it travels on the outside of the wire and the cross sectional area doesn't scale, but 60Hz isn't going to do that much.

If you think "I know, I'll wire my home/datacenter/yacht with 12v DC power!" Then you really care about voltage loss. If you want to move 2000 watts 10 feet with low loss you will be using two copper conductors about the diameter of your thumb. This is why you see 48v used on things like Power Over Ethernet. That is the "low voltage" limit for some regulatory agencies, and they want to get as much power of the tiny conductors as possible.
To be honest, unless you are compiling a giant C++ app or perhaps 3d rendering, developers put very little load on a machine. Consider that we typically write text files and push them remotely for execution. A 486 was sufficient for that.

A few years ago getting enough memory together to run a VM or two might be the largest issue/load. But now memory is cheap and cloud/containers are popular. Containers have breathed new life into my 5 year old machine.

Have them put money in an escrow account. I have done freelance work since I was a kid and one thing I've always done was ask for money upfront, maybe not in my hands, but held by a 3rd party. Losses of 15% seem a bit high too me.

Writing software for someone else is kind of like painting a scene from someone's dream. There is a good chance you wont hit 100% of what they were looking for, and your goal is to make them just happy enough to pay you. If they part with their money already, they are much more likely to accept what you give them, than if they haven't already bought it.

HFTs don't corner the market for a particular instrument. So what's really happening is more like the market for limited- release sneakers. They rush to the store, they buy up a bunch of sneakers. Now they're holding inventory. They only make money if they can sell that inventory off for more than they paid for it.

But there are thousands of other places where the same shoes are being sold. If the demand for the particular sneakers they bought climbs, they will make money. But it's just as likely that the demand will fall (in fact, it's much more likely that demand will fall in the instruments HFTs trade --- that's what those instruments do! They take random walks!), in which case that inventory they bought is a liability.
I prefer this too.

> For a small network (a home or small office network for instance) you likely have one incoming router anyway, so if that dies clock setting is the least of your worries until it comes back up, meaning setting the internal hosts by that one clock is as fine as anything else.

I'm not so much worried about the router dieing and losing sync with the outer world; but about the router's clock going wonky: I've seen computers where something got initialized wrong and they were 30 minutes slow after 10 hours (reboot helped in that case, but sometimes it's the oscillator is just too far off)

At the time of Edison, they already had AC transformers that made AC voltage conversions either up or down very easy. All you need is an iron ring, and you wrap some wire around it.

DC transformers only recently reached comparable performance, thanks to semiconductors, and efficiencies are not as high as a good AC converter without really sophisticated circuits.
Microsoft is (finally) making a change to its research team
Yes lower fees for drivers and passengers. Uber is wasting too much money on shtick marketing, too many managers & executives and expanding to other countries with anticompetitive laws. My approach will involve a relatively smaller operating team. We will not need 20 billion to compete directly with Uber, because our goals are different from Uber. Having Uber as a competitor provides a clear contrast for potential drivers and customers. Easier to compete when you are lean & understand the market.
Facebook trialled this feature on smaller markets before the large rollout it's getting now.

As a contractor you always pay for your own benefits. Every contractor does this (or chooses not to on their on volition). Every driver KNOWS they are a contractor, they should know what comes with being one, and it's no ones fault but their own if they don't.
I think scalping is a really bad example of what HFTs are actually doing (see https://news.ycombinator.com/edit?id=10981812).

But scalping is an interesting example for another reason. Ticket scalping is a response to an extremely inefficient market. Scalping can only be profitable if people are willing to pay more than face value for a ticket.

It might make sense to restrict scalping for tickets, because artists might want to make tickets available to people across a wide spectrum of means. But that is never the case for tradable instruments. Restrictions on scalping deliberately seek to impede price discovery. The whole point of liquid trading markets is that the price of the instruments being traded is supposed to reflect their actual value.

> But that's not the point. Sexism, in reality, favours men and hurts women. That's why an image of Brad Pitt is okay, whereas an image of Emma Watson is not okay! (and by the way, they are suggestive)

> Any argument that goes "But if we switched genders, then it would be fine!" is completely missing the point that we are still living in a de-facto patriarchy, where objectification of men is not even an issue.

I'm talking about his co-workers reactions to said images (whether Brad Pitt or Emma Watson) not about sexism. As a matter of fact I don't see how the two are related at all, what in this scenario is sexist? But since you brought it up; I do not agree with you at all because I think sexism (or the "patriarchy" whatever you want to call it) hurts men AND women. Even if it might not be the same type of hurt or even have the same effects. I think the biggest problem for us as people (humanity) is when we start quantifying and differentiating between different types of "hurt".

> In any case, I found the choice of images immature and closed the website right away.

Pictures of an adult woman's face are immature? You say it is suggestive but I don't find them suggestive at all, does that mean I'm immature or not?

Like I mentioned in my original post I don't understand the standpoint of OP and neither do I understand yours. What makes these images immature and what validates the OP's reaction that he wanted to protect his female co-workers from this imagery. Or did he try to protect himself from the reactions of his female co-workers to this imagery?

Again none of this is meant to be taken as an insult or attack I would genuinely like to understand why you feel this way.

The main problem the article is talking about is tracking 99th percentile issues (e.g. tail latency) which, given the nature of sampling is difficult to capture otherwise.

Overhead is an issue with instrumentation, but as the article mentions, there are a number of clever ways to minimize it. Some simpler examples are physical probing and dynamic instrumentation. FTrace might be a nice example of instrumentation on Linux worth looking at.

The Useless Agony of Going Offline
I think the largest problem is that HR really has no understanding of what to ask the candidate in order to gauge whether or not they're a useful fit for the objective they're looking to achieve?

In general, I feel that a couple of technical questions relating to the fundamentals of the platform you're working with. Getting a feel for who they are and their track record for either delivering on the stack you are working with or in delivering on stacks with which they have little initial familiarity. Some people are particularly adept at learning entire stacks and delivering solutions in times that other developers are incapable of delivering on stacks with which they claim intimate familiarity. Others are amazing at delivering on a particular stack but have no clue how to achieve anything outside that stack.

I think the biggest issue is that interviewers have no idea how to abstract contextual information when removed from their development environment. They think that everyone needs to look and think like them... and if they don't, they're not a good fit.

As for hiring people they like that are technically inept vs. turning away candidates that are technically adept but awkward. I guess it comes down to social aptitude - being technically awesome is only half of the requirement. You've also gotta be likable or you're not getting hired.

"Money won't make you happy" is someone's naive, illogical reversal of the underlying, relevant truth: Lack of money will make you fucking miserable.

Sure, just because luck of money will make you fucking miserable doesn't mean that the abundance of money will solve all your problems and make you happy. However, that is largely irrelevant because most people don't even have that "problem". Someone could hear that silly adage thousands of times throughout his life, and never find out first-hand whether it is true. Proverbs and adages should have broad applicability.

The saying "money won't buy you happiness" (and its various other versions) has a purpose: it expresses a kind of exasperated defeatism over not having money and trying to be content anyway. It's a version of the human behavior which is exposed in that true piece of wisdom known as the Sour Grapes Fable. The fox cannot reach the grapes, so they are declared sour (i..e If I did reach those grapes, it wouldn't make me happy, because they are sour! We just have to identify the struggle for grapes with money. Most of the time this "cannot buy happiness" adage is not only heard by those who will never experience first-hand whether it is true, but also uttered by those in the same boat.

There is a universal truth in it and it is that there exists a human predicament of not being satisified with what one has. It's not always possessions. Someone who has lots of possessions might be dissatisfied with something else in their life, and not necessarily the quantity of stuff. Perhaps he or she seeks to be more learned or skilled in something, or to have a different personality. Or to make some mark in the world other than being remembered as someone who had lots of stuff. I can tell you that if you have more money you will be happier in a sense, but you will still strive to achieve some other satisfactions.

yes, it's a much better idea. i've lost 30 pounds in the last 6 months by cleaning up my diet and working out.

at the end of the day, losing weight is work. there's no way around it. work is generally slightly uncomfortable, and if you're not at least a little bit willing to endure that, you aren't going to see results. i treat gym time and kitchen time like office time. it's just work i have to do. it's not a big deal. after i get this work done, i can relax and chill out and do something mindless.

and really, in the end it's an individual decision. you have to decide, do i give a shit about this? you don't have to give a shit about it. if you don't, that's fine. if you do, then get to work.

maybe in 20 years things will be different, but that's how it is now.
