Data centres don't create many jobs. In 2011, Facebook stated that its data centres create roughly 1 job per 790 m² [1].

Apple's planned data centre is 166,000 m². That gives us a figure of ~210 jobs for this data centre. But that's based on a figure from four years ago, and given how aggressively companies have pursued automation and on-site staff reduction in data centres, it's likely that the 2015 figure is lower. Maybe a lot lower.

Eh. IBM chip is faster at IBM selected benchmarks? Shocker. Also no mention of price.
No, that's an engineer. "An architect is a person who plans, designs, and oversees the construction of buildings."

Blueprints can be analyzed to verify the design correctness from an engineering perspective. That a bridge depicted will hold so much weight, for example. UML has no such utility. This is another bad parallel being made between civil engineering and software. Give it up.
The primary reason is a long investment in wind energy, which could be a good reason for Apple to pick up Denmark.
Why not do both? They are orthogonal marketing tactics.
Yes, but when half the core packages on the system list Systemd as a requirement to be installed, this doesn't really work.
The typical consumer would probably just give the app access to the GPS. The hard part is getting them to download it.

After reading the article just realised why didn't you use mechanize with beautifulsoup library in Python. I feel you could have succeeded in your first attempt within 3-6 months. I did it in 2008 and it worked great for me. Also look at another open source project called scrapy http://scrapy.org/

Does it have nuget (and / or npm etc) support? Pretty essential feature for a .NET IDE
Wow, as someone who just made their first public repo I can't believe GitHub doesn't already offer this. Great idea considering I've been checking my profile constantly to see if anyone's starred or followed me. With that being said, trust is my biggest barrier to entry right now. I'd be devastated if using this somehow affected my repos.
Apple Watch Could Be Your Next Big Opportunity into Appreneurship

(writer of the blog here): Eh... hm.... I really don't want to get into conspiracy theories here. To be honest, during the whole Formula Zero championship we got absolutely zero interest from any fossil fuel companies. I haven't posted a good picture of our kart yet, but our biggest sponsors?
- Greenchoice (a grid energy provider with a focus on renewables)
- DSM (plastics manufacturer, mostly because of our innovative use of composite body parts)
- University of Delft
- A whole bunch of mechanical suppliers (Rodac, Swagelok)
- A whole bunch of electronics suppliers (Chroma, Cyner, Betronic)
- A logistics company (van Kaathoven)

Even the organization of Formula Zero, who had a pretty strong foothold in the fossil business through their renewables programmes, didn't get any attention from fossil fuel anything.

And this barely changed when the competition dissolved into Formula Student. Even though this is one of the biggest student competitions in the world, it doesn't get nearly as much sponsorship from big oil as e.g. the Shell Ecomarathon. If they were really interested in getting enthusiastic, almost evangelistic people on the case to promote hydrogen as the next big thing, they would sponsor Formula Student.

You seem to be parroting the unproven legal arguments of one of the parties to a DMCA lawsuit. The statute is fairly clear in what is required:

(vi) A statement that the information in the notification is accurate, and under penalty of perjury, that the complaining party is authorized to act on behalf of the owner of an exclusive right that is allegedly infringed.

So if I send a DMCA takedown notice, I am stating under penalty of perjury that I have the right to submit the DMCA takedown for the property allegedly being infringed. It is quite clear. So if you send a DMCA takedown notice for something you don't have the right to - but claim you do - you have committed perjury.
I am sure that advertisers would like the data if unavailable via other means, redundancy is being offered by this technique.
Get up and Go
Looks good. See you there.
Systemd has been in use for a little over 4 years. There may be some issues with distro specific implementations but that should be flushed out in the normal debian testing which had been going on with systemd for over a year?
Wireless Power Outlets Using Raspberry Pi
Let me get the plug in first: if you are on a Mac, try Dash, the app that looks up docs for you. I have it mapped to a keystroke in emacs, and I can sometimes park the cursor atop, say, the word 'render' and look it up in one motion.

(Sometimes it takes more motions, because Dash knows the docs for everything and sometimes doesn't get the context right, but that might also be driver error: the app is always politely telling me that I could learn to use it even better.)

Docs aren't always the best tool but it is good to have them at your fingertips.

patio11 is on to something when he suggests using your own codebases. Keep them all on your machine. Learn how to search them. (I use emacs and its various project-directory search utilities like Projectile and Helm, but there are other tools.)

If you don't have any Rails codebases to refer to yet, Michael Hartl is here to help you.

Your personal library is best because it comes from your perspective and with your memory cues. It also only covers use cases you have actually seen, which sounds like a bug but which is actually a feature. The problem with trying to use public docs as references is that they cover all the features that you will never use.

One drawback of your personal library is that it will always feel obsolete. This is a good thing; it means you are improving. Fix it up in bits and pieces where you can. Borrow ideas from the pages you Google.

There is a school of thought which says that you should use your public Github profile as your personal library. Having dabbled in this for a while, I now reject it. Do not write your notes for an audience larger than one. The amount of time you spend thinking "is it dangerous or embarrassing to record this line of code in my private personal repo?" should be zero. If there is anything worse than having the internet read over your shoulder, it is imagining the internet reading over your shoulder. Buy a big private Github account, use Bitbucket, or run a private server for your hacks and notes.

Take notes on everything you do. In particular, get in the habit of pasting the command-line things that you do into a cheat sheet. This is the beginning of devops wisdom. One reason why the advanced deployer does everything with a script (or Vagrantfile, or Dockerfile) is that the script remembers the steps for you and can be looked up later.

It's 2015 and people are still making false dichotomies with sysvinit.
Don't mobile devices store their battery usage over time (and also the per-app breakdown of energy usage)? I don't know what precision the stored data is in, but if it's precise enough, you could reconstruct past movements using it. E.g. when you arrive into a country, the border control could "track" your steps back for a day or so.

Ask HN: How do I contribute to open-source projects
This has been bothering me a lot for quite some time now, whenever I use open source products I can't help but feel bad for not doing anything to help improve the product I use or any other open-source projects which are alive thanks to people spending their time for free.

I want to contribute in code, but I always feel like I am not good enough, or that it would take a long time before I submit my first piece of code to a project.

How did you get in to contributing to open source? Is it possible to contribute to a project that's been there for a long time? if so, what does it take for someone to contribute in code?
The problem with this software is, sadly, not that it was adware at all, but that it was adware which contained a critical security flaw that compromised the computers Lenovo was selling.

If Lenovo had sold the machines with secure adware, there'd be no real problem.
Just throwing this out there. I'd pay double the price of this if you included amazing F# support.
Which is 4 years ago if I am correct
Use systemd?
Looks nice but as a current Sublime user, I'd like to know about plugin support.

It may be because I'm only able to see the mobile site, but whilst I can see a mention of "themability", I can't see any mention of extensibility via third-party plugins.
They have an entire logind replacement called LoginKit (which uses ConsoleKit2 as a backend), so that's hardly "no visible activity".
Domestic users also have to spend effort to check that nothing was compromised by this malware. That is in fact quite hard, and people will spend a substantial amount of time on it.
Big Data is Not a competitive advantage
I would guess that even if the curve is different from say 50% to 40% than 20% to 10% for the same journey it would be easy enough to normalise the data after profiling a couple of phones.

That's what "diplomatic stability" means.
Why would this be an issue of privacy laws? It's more just a case of faulty merchandise.

The complaint is not that Lenovo shipped adware, it's that they shipped computers which were unable to make secure network connections over HTTPS. That's like selling a car whose brakes don't work, not a privacy issue.

However, the actual amount of energy in those ultracaps isn't that much. We're talking a couple tens of kWs or, in other words, all those caps together don't even hold the same energy as one single li-ion cell (18650 size). The energy density is low, thus, the actual safety issue is fairly minor.

That being said, they are in a special Nylon enclosure with polycarbonate sides which provides an effective shield in the case of rupture. But, at the moment that picture was shot we hadn't actually tested that yet :D

Again, students.

Does it being presented as evidence in a US court mean I can freely copy it, including if I am outside the US?

If the creators were freely releasing the film, then I would have expected them to say so in some public announcement.

>I know this has been discussed all over the place to the point of exhaustion but I am still somewhat shocked that Debian adopted systemd so quickly. For a distribution that is known for it's stability and conservative approach to new software I just think this happened way too fast.

Yeah, they should give it a few decades of thought...

And maybe check out if this ANSI C thing is worth supporting over plain ole K&R C.
I guess you know *BSD might eventually adopt something similar.
Which won't allow you to install certain core pieces of Debian software which have decided to rely on systemd.

If I understand Devuian correctly, they will port releases of core software off of systemd and back to init, giving you the option of still using core software packages without systemd.

> Devuan will derive its own installer and package repositories from Debian, modifying them where necessary, with the first goal of removing systemd
Maybe it's relative to systemd reach in the OS and the fact that it's not a no brainer (this topic as proof). How many deep changes Debian did before (I think there was a glibc/eglibc swap at one point) ?
If you’re having trouble testing legacy code, mock a logger
Completely disagree. Entertainment is the first to go when there is a crisis or somehow we return to basic needs.

Edit: Also, not that it matters, but I have studied anthro for many years.
(author here): this is part 1. I will go into other types of fuel cells in a future part. Hydrogen is the focus of the first two parts just because this is the most mature technology and has actually been used in a couple of (kinda..) production cars.
Huh. I didn't know that about Fedora. I admit I don't keep up with the Red Hat world as much as I should. So, apparently systemd has been in production distros for, what, four or five years now?

I don't remember the systemd transition in Arch being too bad, though it was sort of rough around the edges. I guess that roughness is why (mentally) I hadn't expected anyone to have adopted systemd before Arch.
Ireland also has a lot of other things going for it that make for a compelling business case. A highly educated English speaking work force that doesn't cost near what an equivalent employee in the US does. It's in the EU and the Eurozone. Land and buildings are inexpensive. It's a reasonably desirable place to live in Europe for other Europeans.
Around 1998 or so. They always were an incompatible mess of differing configuration formats, "standards" and kludges, but it was ok for the first 2-3 decades of UNIX...
The "draconian" US corporate tax rate isn't so draconian when you consider the capital gains rate is way lower than most places, including Ireland.
My baby daughter is five days overdue. My three-year-old son keeps asking when he'll be a big brother. And my wife and I are trying to figure out how we'll do the grocery shopping—or even focus on a computer screen long enough to shop online—once we're juggling two kids. When I told my wife about Magic, she visibly relaxed. This service has huge, huge potential.
>you need to know the proper systemctl incantation

Isn't this true for all commandline programs? It's a different way to do things in many ways, but this argument doesn't really talk about the merits or pitfalls, only the fact that it's different.
So systemd is doing a reverse proxy for Apache in that configuration? Or is it launching Apache on demand like some sort of advanced inetd?

Either way, netstat -nlp isn't lying about who owns the port 80 socket. It's a terrible idea, but the data returned is not incorrect.
Neither of those links imply that PrivDog is bundled with those apps. It just mentions it as something you can download.

Edit : Just re-read the linked document. Yes, it does indicate that it's an install-time option. However, I've yet to see confirmation that Comodo software comes bundled with the SSL-intercepting version of PrivDog.
It's actually because of, I'm sorry to put it so bluntly, distribution maintainer incompetence in the form of not modularizing common script functions, bolting on hacks like start-stop-daemon, startpar and insserv to achieve primitive asynchronicity and service dependencies, and to an extent the failings of sysvinit itself with providing little tools to contain the environment and enforcing messy symlink farms.

What you're doing is the equivalent of looking at some old Mach performance statistics and concluding that microkernels cannot possibly work... never mind there's one alongside every smartphone.
Just this periodic strange urge to adopt superior technology that fixes several broken things at once, instead of keep going with what you're familiar with and sorta-works for decades...
Favorite quote from the above paper: Albert Einstein once said, “We can't solve problems by using the same kind of

No, I don't think HN is very smart in this regard. Holding an opinion that is seen as devaluing the state of software on HN will get you knee-jerk downvotes and subsequent hellbanning.
I don't think it should be surprising that few users actually look at the code or are willing to dig into a foreign code base. It's still true that open source makes it possible, which is a huge step up from any other model. There's a lot of backlash right now due to some very high profile bugs that have been around for a very long time. But would those bugs have been found if the programs hadn't been open? Also, look at what happened after heartbleed: Another group of people decided to dig into the openssh code base and try to clean it up, finding and fixing lots of other issues, without any authority from the original authors. That's the benefit of openness, in my opinion.
> Sadly the other options are quite limited

Jordan Hubbard already said that FreeBSD needs an systemd equivalent. OS X was the first one to get one, Windows traditionally has a general design that resembles systemd much more than any other init system. I think you are running from reality.

The v0.13.0 release is the largest Hugo release to date. The release introduced
some long sought after features (pagination, sequencing, data loading, tons of
template improvements) as well as major internal improvements. In addition to
the code changes, the Hugo community has grown significantly and now has over
3000 stars on github, 134 contributors, 24 themes and 1000s of happy users.

This release represents 448 contributions by 65 contributors

A special shout out to @bep and
@anthonyfok for their new role as Hugo
maintainers and their tremendous contributions this release.
Familiar shoes I've walked in. Build something more than the typical blog or book inventory site you see referenced in tutorials. If you can't think of something to build, then think of one of your corporate Java apps and build that in Ruby/Rails from scratch. Or if you want a side project then pick something and literally copy it in your own way. Like a photo sharing site or whatever.

Things to include in your example app so you can learn the ins/outs of how rails does it:

- Nested models: comments on photos and how to organize the models, many to many relationships

- Rendering Partials: you can factor out pages into partials and essentially load them anywhere in the app

- Gems ecosystem: check out rubytoolbox (.com I think) for categories of gems. These are like Java JAR files you can include via Maven. The popularity and activity level are good ways to assess usefulness (outside of requirements)

- Host your own server: learn how Rails apps run on a server and different options for running it. There are providers out there like Heroku where you can just deploy to them but I think it is best to understand how these work. You probably understand how Tomcat or other Java containers work, where to look for log files, how it might interoperate with Apache HTTPD, etc.

Yeah, number of eyeballs helps but it's not a catch-all. In some ways it could actually be a hindrance, since less-experienced eyeballs may not be able to mind all the necessary details, or may introduce further bugs/vulnerabilities. For our purposes, these are "bad programmers", whether or not they're good programmers on other stuff.

A simple model for code quality is something like Q =(good programmers) / (good + bad programmers). I would actually argue that it's not even related to the average, and that bad programmers can degrade quality disproportionately to their actual number. I think it might be something closer to Q = (good programmers)^2 / (good + bad programmers)^2. This is what it seems like people are getting at with the whole "negative productivity" in the good/bad/10x programmer framework.

Openness/closeness of the source code isn't the whole picture but the open-source model can more easily run into the too-many-cooks problem if the source is not properly gate-kept and reviewed in the aggregate. Thus I don't think it's entirely orthogonal. Of course closed-source software is typically commercial, which runs into its own set of pressures that degrade code quality.

I think much more sophisticated testing systems are what will really boost code quality. More advanced detection suites that throw more warnings, mandated full unit test coverage, plus CI frameworks that make sure that your code isn't merged if it doesn't clear the warnings and pass the full-coverage unit test. Randomized address systems and mandated array-bounds checking that catch undefined behavior and off-by-one errors. Basically, making things fail noisily instead of silently and forcing contributors to pay attention.

The C compiler in particular is really bad on the "throwing warnings" thing, even before you get yourself into other kinds of trouble. As in, according to the C standard, "rm -rf /" (or literally any other behavior the compiler wants) is a valid output behavior if you miss a closing quote([1]), rather than a compile-time error. That's an absurd definition in a security-minded world, and that's just the most egregious example of undefined behavior allowed by the C standard.

JVM-style managed code and declared exceptions are annoying but do seem to be a step in the right direction from a security perspective.
