While he is correct that slow walking doesn't burn many calories in itself, there is also evidence[1] that even mild levels of exercise act to increase your metabolism significantly.

This means that the benefits outweigh the simple measurement of calories burnt, especially for people who are otherwise sedentary.

Developers don't install the consumer JRE anyway. They install the JDK which doesn't do this. I doubt it'd make any difference to Android.

Meanwhile, for apps like Minecraft that want to distribute consumer Java apps, just bundle the JRE. It's quite easy these days.
I have a wireless mouse that works via a USB dongle, and I use a USB headset for my Skype calls with my business team. I also charge my cellphone from a USB port, especially when travelling, as it's far more convenient to have one plug adaptor and my Macbook Pro power supply than carrying a plug adaptor and a multi-box everywhere.

At the moment, the two USB ports I have on my MBP are pretty much bare minimum but every now and then I find myself juggling peripherals.
Well that's certainly one point of view.

authorities in the U.S. and U.K. ... oppose end-to-end encryption ... In a statement, [German] interior minister Thomas De Maizière said encryption was an important requirement for Germany's desire to take the lead in the provision of digital services.

If encryption becomes the norm in Germany, I could imagine more demand for technology that integrates with and is compatible with end-user control and confidentiality, more of it being developed there, and they could indeed take the lead in those areas.

The fear is not that Starfighter dominates; that would be a good case.

The fear is that there are a bunch of hiring fiefdoms, all waxing and waning, so that I have to spend a bunch of time on a bunch of them to stay relevant. I don't want to be laid off one day and then find out that these days employers are using StackOverflow scores or wherever and that I should have spent the past year working on that.

OTOH, if 1) I can easily find out that SoftwareCo is hiring through Foo-CTF without having built a Foo-CTF profile, and 2) I can spend, say, 5 hours building a profile at Foo-CTF and get a serious response at the end of that, that's good. It means instead of spending 5 hours doing the silly technical interview dance with SoftwareCo, I'm spending 5 hours doing the serious work-sample test with Foo-CTF. Foo-CTF's value-add is that they're experts at doing the work-sample test.
> Last month my fourth iPhone in six years was, in medical terms, crashing. The screen, which had pulled away from its glue, was behaving strangely. The charging port, no matter how thoroughly I cleaned it, only occasionally took power.

Maybe a solution is to treat your next expensive phone with a modicum of care? My partner and I have each had four iPhones over the same period with one cracked screen, and that's it (and I consider us heavy users). I can't even picture how to make the screen come unglued if I wanted it to...

It is hard for me to believe that macbooks (that receive all the attention) are always getting the royal treatment, when macbook pros are more expensive, and are (regularly) paid for by a business. Furthermore, my niece in college does not need a new macbook as often as I (as a professional) need a new macbook pro!

Fair point, my argument is that rather than saying salary is 100k, they should be saying total compensation is valued at 110k with 100k being salary, parking being valued at 7k and donations to the upper peninsula bird watching society covered by the company to the tune of 3k per year.

I read a bunch of different tech sites, but it my opinion, the most relevant stuff is on HN. It basically aggregates all the best stuff from all the tech publications anyway, so you are probably just as well off in the end. Of course, if you want to read more academic articles per se, stick to the big science publications like Nature, etc.

Here's a list in no particular order:

On your "About Us" page, you say "We're especially interested in talking to you if you will be hiring 10+ engineers in the next year, as we may be able to help you out with that. Get in touch with any of us."

Does a company need to be hiring 10 or more engineers to make it worth it to talk to you?

I'm at a small company, that has been trying to hire engineers for the last couple of years, and not having much success; we've hired a couple, had a couple take other offers, lost a few to attrition.

We would love to be able to get some candidates who have already passed a technical screen; less time for us, scheduling an hour with a bunch of candidates who don't pan out, less time for them, only focusing on one more in-depth set of problems rather than a whole bunch of different phone screens.

But we're not hiring 10+ developers any time soon; that would double the worldwide size of our dev team. We're looking for maybe 3 or so at this point.

Would you consider working with smaller companies as well?
Other interesting lessons discovered:
1. You could run an >100' >100kbps rs232 link for over a year without issue. Proper wiring and rs232 length limitations be damned.
2. You could wire up an rs232 link (-12V and +12V) directly to a TTL input for over a year without issue.

People exceeding the defined limitations of things seemed to know better when it came to exceeding defined limitations.
Yes this has been a pattern we have seen as well, but as the market has shifted away from employees and more towards contract based employment we have seen that dynamic shift some. Also as we have focused on being a distributed team we have seen more contract based work. That is the piece we are all missing is a longer term relationship with a company that we are more of a permanent fixture with.

Right in so many points:
"Now, it's all about the style": that's right, it's an accessory, it's the long awaited iPad pro + keyboard, a glorified browser for your social network, check photos and look chick and trending.

Why are we here? People have decided with their pockets, Apple is now the biggest company in the history of humanity.
Don't get me wrong, Apple has done a lot of stuff right, the amount of design and engineering behind the original iPhone it's incredible, and yes maybe a lot of the technology already existed but they polished the combined products until they got something that worked in such a nice fashion; that's the "magic" behind their products but from there is downhill.

iPad: bigger iphone.
iPad mini: mini- bigger iphone.
MacBook Air: let's trade some some performance and take away the capability of upgrade the machine in a pursuit of a more thinner machine.
MacBook: let's take the least powerful CPU from Intel (the reason behind the no-fan design"), cripple the typing experience, take away all upgrade-ability, cripple the semantics of touch from the track pad, take away all the ports.... WTF.. charge for the hub... and make it more expensive.....

But I think the problem is not Apple but the people buying their products and how they use them. It's a super glorified version of "I belong to the better group" psychology.

now that I type all this... it could make some sense to start looking all this not as a computer... or apple as a computer and software company but a boutique selling accessories.

I would love to tell you that thinkpads still make sense but the "no leds" and "screw keyboard" may prove me wrong.
I found that using brew to install GNU tools and replace Apple's FreeBSD tools really made my transition a lot easier. Now build tools don't randomly break because of some unusual command line incompatibility between OSX and Linux.

Annoyingly at the end of the day, I just want a Unix OS with working drivers, and that can run photoshop. Linux doesn't quite cut it (no matter how much I love it).
>Where are the apps that are even half as feature-rich as a typical Windows application from the '90s?

I hear you. One reason for this is scalability. You can build richer web apps if you aren't shooting for scale.

I worked on two startups with conventional LAMP stacks and heavy user sessions before joining Yahoo. At Yahoo there was really no session object[1], due to scalability. A few cookies could be set to customize behavior, but adding new cookies was seriously frowned upon. This made me appreciate sessions as a means to adding in nice little features.

In principle you can solve that by storing the session in a scalable key-value store, providing the latency is low enough.

Indeed. If you have dedicated parking with a charger, it's far more convenient than a gas vehicle. If you don't, it's terrible.
A lot of contradictory comments on this thread:

> This means that the benefits outweigh the simple measurement of calories burnt, especially for people who are otherwise sedentary.

> It was my understanding that if you're largely sedentary, no amount of exercise can "make up" for that, and that the correlation with increased morbidity and mortality remains.

Some say that even a little helps, some say that even large amounts of exercise still isn't enough.

As a largely sedentary person, I wish there were more concrete studies done to show how to mitigate the risks of long-term problems for those of us that are sedentary for a (relatively) big part of the day.

FreeBSD 10 on the EC2 boxes, whatever Linux AWS is running on their managed service instances. Nginx backed by Python and Go servers.

Plus a smattering of other services like ELBs, etc.

I can't imagine having something so critical that you build a custom Nginx plugin. I thought I was cool for doing a bit of Lua scripting. :)

But I'll play along. I'll be taking Starfighter in a new direction. Most notably, we'll be reorganizing how we react to online discussion. Anonymous critics will be summarily executed unless we cannot identify them, in which case they shall merely be barred from Starfighter for life, which, if you believe our marketing department (AND AS CEO I DO IN FACT I'M SORRY I IMPLIED IT WAS POSSIBLE TO DOUBT THEIR CLAIMS), will make it very difficult for them to find work in the hiring utopia that is the post-Starfighter process.
Apple's slowly becoming a fashion company. I'm being only slightly facetious.

I'm not an Apple hater despite saying that. If anything, I usually prefer Apple products over the competitors, and I've used iMacs or Macbooks for years now. But, between the $17k gold Apple Watch and the recent updates to the Macbook Air and iPad lines, it seems clear to me where Tim Cook is taking the company. And I don't think Apple as a fashion company is even a bad thing, it's just a transformation that some will like and others will resent.
I've always found if it was really important, it would show up in my twitter feed or HN - So rather than going to the various sites, I just use those two as my meta-index.
This machine also has a weaker CPU. I'm guessing it would output less heat.
Seems like many of the comments here are/will be railing on patent trolls and disgusting corporate enterprises making money off of ideas they claim to have come up with. I actually don't know or really care too much about those issues, but as a student working with patent data in a research lab, I hope to goodness they address their bureaucracy. The patent data they put out is way behind the technology we have today and it's really hampering research in that area, and consolidating it is something we're still dealing with that doesn't even touch on the disambiguation problem yet!
I'm just using a simple tactic: if the user follows more than 10k users, that means that he has no interest in my tweets and will probably never interact with me.

So, if I like what he is really doing, sure, I might follow him back. Otherwise, no way.
> As a standard procedure and just as an example, bee-keeper remove most honey and feed their bees on corn syrup

The feeding on corn syrup is generally due to the fact that the bees are feeding on a monoculture. When the bees are pollinating a crop, there is NO other crop around for miles. The corn syrup with additives is an attempt to buttress any dietary deficiencies.
They seem to just dump every current theory in a pile and call this pile a new theory. (Climate change is even thrown in, in the main paper)

I think as a rule of thumb, things don't happen because of multiple reasons.

If someone tells you this is great because of X, Y, Z chances are Y and Z are made up to make the argument.

80/20 rule. There's always a main reason for things, the other stuff is just fluff that really doesn't matter.

This is different to cause and effect, once you destroy a habitat you create a new order of things for an animal. Then disease might turn into the 80%.
You're just agreeing with ansible - no one here is arguing that a CS degree means you can code. Rather ansible is relating his experiences with people graduating from those courses and not being able to code.

What you seem to be implying, is that this is obviously true for graduates, but couldn't possibly be true for people with real experience. (But your implication has no evidence to support it)

Exactly why do you believe that it is completely plausible for a recent CS graduate to be able to explain the technical details of their final year project when in reality they contributed zero code to that project, yet it is entirely implausible for someone with 3 years experience to be able to be able to explain the technical details of their most recent development projects when in reality they contributed zero code to those projects?
Code that doesn't have patent protection isn't very useful to people who live in countries with oppressive patent laws.
Why does it matter if your build system takes a while? You shouldn't be pushing it to there until you are happy it works locally, at which point you can move on to the next task and forget about it.
The Boy Whose Brain Could Unlock Autism
It's awful for consumers, though. And for developers, it's not great, either, because you end up having to support a customer on an old version of OS X, for example, which means keeping a suitably old environment around just so you can keep your builds compatible, or jump through all kinds of hoops.

I don't feel like this is a good thing to encourage in an industry that already has more than enough churn as it is.
They weren't delivering power over Thunderbolt (though technically possible I think).

By moving to USB-C they are now on tech the rest of the world is likely to pickup.

It's also pretty likely that it's more power-efficient than Thunderbolt and less complicated. (The Intel Thunderbolt controller is a mean looking IC that gets pretty hot)

Something is always better than nothing. It might not increase your long-term longevity, but will be of great help in an altercation or simply playing with a child.

> I was hoping apple will... retinafy the regular air

I doubt that's happening soon. With this new macbook on the market, the only use Apple has for the Air is as a budget option. The new macbook is smaller and lighter, the only advantage of the air is its 12 hour battery life compared to this thing's 8, but that's to be expected considering how gutless the Air is.

If one takes a bit of time to choose well, it's possible to buy good quality stuff at almost steal prices. Think Moto E, Acer C720, Nexus 7, Casio F-91, Duralex glassware, etc. None of those qualify as shit-x, yet their prices do.
> it is assumed that you spent several months preparing for coding interviews.

Not all companies are like that.

The point for prepping is that you're likely going to go through several coding interviews at a variety of companies, and the upfront prep time is to kick the tires on those skills.

Whiteboard coding is a skill, and like any skill can be mastered with practice.

We turned old articles off a few hours ago as an emergency measure because the site was being crawled aggressively and our poor single-core Racket process couldn't keep up. Previous solutions that have served us well until now, such as IP-address rate limiting, appear no longer to suffice. If you noticed HN being unusually slow earlier today, that was why.

Sorry for the inconvenience! We've turned everything back on for the time being.

Our interim solution will probably be to cache the html for old articles, since nothing about old threads ever changes. This is not a perfect solution because, for those older articles, logged-in users won't see their usernames in the top right, nor will they see which items they voted for or the orange asterisk beside their own posts. But everything else
should be there. Edit: oh, and those of you with a custom top color won't see that (on older items) either. :(

We have a better solution in mind that will restore the per-logged-in account details to the old threads, but that will take longer.
Performance thought:

I like the way you raytrace the entire image at once. Clever, but you might be able to make it faster...

Right now you process the entire image in one hit. However a 1080p * 4 byte image is 777,600 bytes - from a quick read I believe you have several of these. They're large enough to blow the caches in your CPU.

It might be much faster to break the image into 8,16 or 32 square or rectangular or line shaped "patches" and process each in sequence. That would help you hit the same parts of your working arrays more often and keep them in cache between iterations.

I'm thinking

for patch in patches
for iter in iterations <-- currently your outer rendering loop

Might be a quick performance win worth playing with.

Amazing article, thankyou!
greggman is talking about dependencies between build targets (such as files or directories or projects), eg: "lib.js depends on lib.coffee" + "lib.coffee's last modified time > lib.js's last modified time" = "must run task that regenerates lib.js"
That's the point from the inventor's perspective, yes. If an inventor wanted it publicly available, she'd just publish it. That's generally how science happens. For an inventor, a patent is a way to guarantee ownership of proceeds.

A government, however, doesn't actually care if the inventor gets paid. The government provides a patent office in order to make inventions public. In return, it provides what the inventor wants: a way to defend ownership.

Notice that you cannot patent something without making it publicly available. It's not possible. If exclusion from intellectual property was the only goal, this would not be true. You should be able to register your invention with the government and reference it in court, only divulging its details when the facts of the case demand it.
Thanks, it is very useful and interesting stuff.

where are you getting 30K from?

I only have experience with what CMU will quote a family with modestly upper middle class means, about 10 years ago, but I was unimpressed

the difference back then between them and state school was multiples more than 30K over 4 years

2 things about that 20K difference

1) how much of the can be attributed to better students starting off at those schools

2) I'm not convinced that the 20K a year difference persists over time, the state school engineer who becomes professionally accomplished will get raises, the elite school engineer who rests on their laurels won't

what matters is the individual, not the school
They just say, "especially," and I think a charitable reading would tell us that it's a call to get a good base of early adopters from which more-easily generalizable results can be gleaned.
