I'm apparently like you, none of this make sense to me.

The CLI works like this: I type in a command, I get to see the result (if any) and back to step one.

If doing a `cd` command takes 3 seconds, I'll have to wait for it to be ready to run the next command anyways, because my `rm` command has to run in there or I might have a problem.

For hasty typers like myself this could pretty easily backfire.

By the way, you can type the next command as the previous is running. You might get gibberish on screen, but you're sure it's only executed after the former is done.

Or you could just type several commands like `./configure && make` so that you can switch to something else in between.

In any case I don't see any advantages of an async prompt, just potential dangers.
Definitely! I have a couple issues I need to fix on the hardware so the board runs without mods, but I plan on posting all of the hardware/firmware very soon once I get that wrapped up.
I could see roundabouts being an advantage on smaller one or two lane streets but beyond that it seems like it would get dangerous fast.
There's a lightly fictionalized account of how this was engineered in Richard (Manchurian Candidate) Condon's largely-forgotten novel Mile High.

Personally I don't see any cognitive dissonance in thinking that a messy decades-long guerrilla war would represent both a failure to "export democracy" when taking place overseas and a failure to "defend democracy" if taking place in one's own neighbourhood.
It's possible they're both being sensible. Roundabouts are certainly under utilised in the US (unlike those awful four-way stop signs which are particularly hellish for law-abiding cyclists) so putting more in is a good move.

However, as traffic at any particular intersection increases it eventually may make sense to replace a roundabout with a traffic light. Roundabouts can handle large amounts of traffic, but only if they're large roundabouts -- if you can't expand the actual road space then the traffic light is the best move.
Here are some things I've done recently that seemed useful:

1) Rather than ask them to code something, give them some code and have them review it. I opened up a browser and went to code review.stackexchange.com and picked one in the interviewee's favorite language.

2) Have them show you code they've written. It doesn't have to be from their current job, which would probably violate their employment agreement, but they've probably written some side projects for fun, or worked on some open source, or something.

3) Discuss problems they've actually solved and how they approached it. What did they try that didn't work? Why did they choose the solution they did? Did they consider anything but not try it? If so why didn't they try it?

That way you're not testing their ability to write unrealistic code (who writes their own linked list?) under ridiculous time pressure (less than 1 hour); you're not bringing on test-trauma that wouldn't affect them in their real job, etc.
Why would the OpenBSD team not accept the commits? It is just linking to a system library that will always be present on the platform. It's like saying Windows opensource should be forced to use some thrid party filesystem library.
> This is not genetic but not "necessarily hereditary", this is hereditary, but requiring a combination of inherited "things" to manifest.

Down syndrome is a result of genetic expression but is not a hereditary trait. General, normal human features (like having 5 fingers on each arm and feet) are also genetic but so universal it makes no point describing them as "hereditary".

> IQ, not being a binary trait, doesn't work the same way, and probably (even to the extent it is genetic) the product of isn't a single, simple genetic trait of any kind, but influenced by a number of different genes.

If it's a function of thousand features as been suggested, this makes the odds for direct trait inheritance not particularly good, no?
It leads to interview arms race. People will try to find ways around any sort of objective measure devised. Soon we'll have sexiness! "Your code works. You were fast and correct but just not sexy enough. Thanks for stopping in."

It's cute that there is some kind of VBScript for calling web services, but this line tells me that this document must have been authored by some kind of PowerShell apologist.

Just put none in the `whois` box and move on.

Are the 2 statistics presented in any way related? They say a quarter to a half of the food in the world is wasted and 70% of rural Africa doesn't have electricity but is the food waste occuring in those regions due to a lack of electricity? There are plenty of food systems that don't rely on refrigeration. The food waste is occuring in places with adequate refrigeration, but because food is too cheap and people are lazy!
I think it comes down to unreliable communications... In the case that your POS terminal isn't able to connect upstream, do you completely decline the transaction? Businesses used to accept checks from most people without issue.. these transactions took several days.. yes there was some fraud, but it was minimal.

In this case it may be part of the protocol to not confirm if there is a communication problem, and that risk may be acceptable. It seems to me a test of is "0000" valid and is "9999" valid and at least one of the two rejected before the user is allowed to enter their pin would be reasonable here.

There's a lot to be said for user in/convenience in decision making.
The question should be, what is best for this particular intersection in the near future? The two designs have different characteristics.

My understanding is that roundabouts are best when traffic is low, when it gets heavy they become much less efficient. Lights, while a lot of overhead in low traffic, scale better. There's also the question of space required.

Since the UK may have too many roundabouts due to traffic growth, and the US virtually none, they could both be building the opposite and making the right choice.
It's complicated. U.S. EMV credit is (virtually) all chip and signature. Debit is split between PIN and signature. US Debit Common AID is Online PIN, but you can legally do PIN bypass ("no cvm") or even fall back (or have user select) the card brand's application on the card (instead of the US Debit Common AID), in which case for Visa it will be signature and for Mastercard it will be online PIN. Politics and posturing.
So? We haven't clocked a physical object moving at the speed of light either. That doesn't mean the math is wrong.
In industry its almost unknown.

So unknown that even Microsoft offers git functionality in Visual Studio now: https://msdn.microsoft.com/en-us/Library/vs/alm/Code/git/ove....

Maybe it's not dominating (or maybe it is, don't care), but to say that git is almost unknown is a bit strong, IMO.
Maybe because it's not possible to achieve 0K? It's physically not possible.
For many kinds of tiny one-off hobbyist projects, why bother with servers or dynos at all?

Couldn't help but wonder if the (valid) cost and performance problems the author has with heroku will end up pushing devs faster to Backend-as-a-Service platforms like Parse, Firebase, or something like Amazon Mobile Hub (Lambda on Rails?).

I'd imagine the horses were telling themselves the same thing back when the automobile hit the scene...

Robots have already replaced human jobs. They started with factory labour, but today they're trading our stocks, diagnosing diseases, driving our cars... it'll be a very long time before automation can completely replace the human animal (today, our ability to improvise in a highly unpredictable world gives us a strong edge, which is why those self-driving cars won't be seen on wintry roads any time soon), but I have no doubt that humans will get automated out of work in the fullness of time.
The content is available after it is decrypted in a browser on a single host. If the streams are inspectable by network defenses they can be inspected at much more feasible scale allowing one device to protect 10,000s of hosts from the same malware-laden ad. The alternative is to try and deliver protection to 10,000 browsers, and somehow keep them synchronized which is just so much harder and expensive. Or you could make the host operating system, apps, and the browser resistant to exploitation...

It's not that encrypting secrets is bad (and sessions are secrets). It's that encrypting everything without looking at what you gain and lose is poor engineering and it all seems to be politicized somehow (camps, factions, dogma..) with HTTPS-only being pushed as the answer to one security problem (confidentiality vs active eavesdroppers) at the expense of existing solutions to other problems, including integrity (please don't compromise my hosts), availability (I cannot use recent browsers to admin my equipment because they ban self-signed certs but trust 100+ CAs) and non-repudiation (where did the malware come from?).

It used to be pretty terrible for python. You couldn't use third party libraries that had C dependencies (e.g. Pandas). Now with docker images you can at least define your instances.
Probably so that it can keep running even if no user account is logged in.
I don't see roundabouts as a replacement for traffic lights in the US. Above a certain traffic volume, you'll almost always want to move to traffic lights anyway. They're actually a replacement for the 4-way Stop - a ridiculous type of intersection that ought not to exist.

According to https://www.openshift.com/products/pricing/plan-comparison the free plan idles after 24 hours of inactivity (https://developers.openshift.com/en/managing-idling.html)

However you can work around it by hitting your server with an http request every 24 hours, or upgrade to the Bronze Plan which apparently has $0 base price anyway so I'm not sure what the downside is.
Sorry, I don't understand this response.

Are you saying that you are familiar with the events that DonnyV is referring to but you are confident that they are mere legend? That you disagree with the published accounts?

Or are you saying that you are not familiar with that particular scandal, you've never heard of it, and your response is simply "Not that I know of."?
The UK also has a lot of roundabouts retrofitted with traffic lights (especially at motorway junctions).

No, they wouldn't. They've run the numbers. What they figured out is the cost to acquire a paid user is cheaper by having a free account than by buying a bunch of ads.

Free plans or hobbyist plans are really there to get the marketing and cheap customer acquisition, not to power the mainline B2B business. The main business in both cases is likely bolstered by enterprise clients worth 5+ figures a year, but don't likely cost much more than a hobbyist account to maintain.

If you only had a hobbyist offering, you'd go out of business. As this post points out, Heroku has a much larger common offering where they should have plenty of profit at scale.

Meanwhile, they also benefit from hobbyists saying "oh yeah, Heroku is easy, let's use that!"

Heroku is smart, they know what they are doing.
The headline makes it sound like it's a wholesale thing, but from how the article describes it, traffic agencies in both countries are discovering that some intersections are more useful, safer, etc if they had a different kind of traffic control. As information disperses, it becomes easier for engineers from different countries to share ideas and knowledge to figure out what the best course of action is for a certain type of intersection.
True, but irrelevant. The definition of temperature (average kinetic particle energy) means it exists. Conversely, Absolute Hot[1], is an open question.

As danso notes, the NY Times editor and Amazon's Carney have now made pretty unequivocal contradictory statements, with little room for them both to be right without one of them outright lying. (And I don't think either one would go on the record here with an outright lie.) Except that the NY Times says "But he [Olson] said he was never confronted with allegations of personally fraudulent conduct or falsifying records, nor did he admit to that... If we had known his status was contested, we would have said so". That is, they can both be telling the truth if Olson was lying to the Times about his departure.

That's my prediction for how this shakes out. And in that case, the Times will have egg on their face for having not properly vetted their sources.
Yup, mostly so they can target a bigger market and be closer to large clients. This does not apply to every company, but for SaaS and software companies, I think it is often the case.

I think running a business in Spain, what we call here being an 'empresario', can have some small-but-negative connotations for part of the population, who see the rich as a mere consequence of corruption forces instead of the financial result of providing value to customers. It's not like we haven't had our fair share of large cases of corruption over the last few yours, though.

I think this is also the case in other European countries.
cool I didn't know that - thanks for the info!
As I understand it, most drugs are still a pretty "blunt" from the standpoint of biochemistry. Too much of X causes some problem, so you make an antagonist for X. But X does a half dozen other things, and your X antagonist is going to affect them all. 99% of the time we call them "side effects", and they're bad. It's not that they have "no fucking idea" what they're doing; it's that sometimes there's no way to isolate the system they want to affect. The human body wasn't designed for external maintenance.
The temperature scale has a zero, and that's a fundamentally important temperature limit, so you'll want in on that scale.
Yes, but why is a high bypass turbofan quieter? If I understood correctly, it's because most of the thrust comes from the large slow moving fan, so you don't need to blast nearly so much air through the turbine as a turbojet to get the same thrust.

The whole purpose of decoupling the fans is to give you an even higher bypass ratio - two or three large electric fans driven from one turbine can have a larger swept area than a single large geared turbofan, so can run slower for the same thrust, and hence be quieter.
How does this compare to the standard MySQL performance?
They would simply bring in UN "peacekeeping" force. Problem solve. Foreign military on US soil shooting citizens. I don't know if you have seen UN vehicles staged at various bases around the US, I've seen them at a National Guard staging area. The system is already in place. There have been sightings of UN troop movements along the US/Canada border.

I can certainly see the point where Heroku comes out wildly overpriced for certain types of hobby-scale apps. I've seen several people recommend dedicated servers via Linode or DigitalOcean instead, which has it's own pluses and minuses - gotta maintain the server, but for a pretty low price, you get something powerful enough to run a 24/7 server + database + whatever other odds and ends your app needs, as long as the demands aren't too high.

I'm wondering how AWS compares, though - running a dedicated, manually managed EC2 instance or ElasticBeanstalk. Seems like you could get your own server, and still have little barrier to scaling as high as anybody could ever need at the touch of a button. Anybody have much insight on that?
>> If doing a `cd` command takes 3 seconds, I'll have to wait for it to be ready to run the next command anyways, because my `rm` command has to run in there or I might have a problem.

My understanding is that the cd command finishes before the next prompt gets displayed; the command that continues running in the background is `git status` inside the new working directory.
Oh, I thought this was just a client.
Elaborate please

Edit: Nevermind, I didn't realize that there was thread that could be found if you were looking for it. My girlfriend had one put in somewhat recently and I never noticed.
How big is the VPS you're running it on? I've got a 1GB Digital Ocean box for my side projects already, wondering if I should just spin up another one of those with Dokku instead.
> If doing a `cd` command takes 3 seconds, I'll have to wait for it to be ready to run the next command anyways, because my `rm` command has to run in there or I might have a problem.

I think the CWD is actually changed before the PS1 magic queries for the status of the version control system--meaning that your `rm` would hit the correct target.

But, I'm guessing--I haven't used a fancy prompt like this.
Many? I think it's the vast majority. I'm in the industry I want to be in, but not exactly in the way I want. If one is trading their autonomy for survival, the odds that they are in the job they want seems low and the chance of that job remaining the job they want seems high.

All scientific explanations are fundamentally ad hoc. We get scientific facts through falsifiable models based on evidence.

It’s the same in economics, but economics is a field that is both complex (informationally) and complicated (incidentally), so our models aren’t very good. Often they’re only falsifiable in theory, because a practical assessment would be too costly.

I wonder if this may be attributable to the difference between a CPU bound versus an IO bound workload? I imagine CVS is doing a fair amount of IO, which on a laptop with local disk (and no competing workloads driving IO) may be able to handle pretty effectively.
Also, in my experience, roundabouts work best if traffic at all entrances/exits are roughly equal (within an order of magnitude or two)

If traffic flow becomes highly unbalanced, a constant flow of cars from the primary entrance to the primary exit can block all cars from entering the roundabout at secondary entrances. They have to wait for a car to enter at the primary entrance then take the secondary exit so before they can enter.

I was once stuck at a roundabout for 5min due to a sports event in a nearby town creating a constant flow of south to north traffic, when I wanted to go from west to east. The roundabout useally worked perfectly fine, but was broken by the abnormal traffic.

If that intersection had traffic lights, the impact on non south-north traffic would have been minimal.
I've worked on a (C++) codebase which mixes tabs and spaces for this reason. It works okay - in particular, since my editor is configured for 4-space tabs, while patches are reviewed in GitHub with an 8-space tabs, any mistakes are likely to be caught in review. But it's not that hard to avoid making them in the first place if you remember to use the space bar to line things up.
Yes, of course. If no coercion is involved and someone is stupid enough to exchange a valuable item for a pittance, who am I to stand in their way?

One reason for the general failure of gun buybacks in the US is two responses from the gun savvy:

1) Go back a bit from the front of the line, and if you see a valuable weapon held by a noob (vs. a likely crime weapon), buy it on the spot for a lot more than what's being offered.

2) Gather up clunker weapons with values much less than the $100 or whatever they're offering and make out like a bandit.

This article has much more detail:

http://theflyingengineer.com/flightdeck/pw1100g-gtf/

The gearbox is described as the epicyclic type with the compressor driving the sun gear and the carrier of the five planet gears driving the fan. The article doesn't seem to identify any extra special sauce. It points out that geared turbofans have been used on an airliner in the past, and identifies some design trade-offs. "there may be a performance penalty, marked by slower cruise speeds for the same thrust setting, possibly slower max cruise speeds, slower green dot (best L/D speed), slightly shallower climbs, and possibly degraded single-engine performance. The single engine performance difference is expected to be the most prominent, with a possibly larger yaw, and a definitely reduced climb gradient, consequently lowering obstacle clearances."

My impression based on just reading that article is that, rather than a technological breakthrough enabling the geared approach, Pratt and Whitney have explored a rather neglected area of the design space, to arrive at a more efficient, lower noise engine with slightly worse performance in some other respects. And had to conquer numerous 'ordinary' engineering challenges to make it work.
