The author's argument for this post is rather poor. He states that the raw data plot is noisy and weakly correlated, thus no relationship can be drawn by averaging the data into sets of buckets.

While the author is correct in that averaging hides the variance of data, he does not try to answer the question of "Can a trend be found from noisy data?" or show other accepted statistical methods that show no correlation in the data.

Instead the author dismisses the report from Gates through name calling: "It seems like the point of this ‘research’ is to simply ‘prove’ that Gates was right about what he expected to be true. "

In my experience it's enough to version control custom parts of wp-content (you theme, your un-published plugins) as everything else is better left to Wordpress one-click updater.

Google went back on what Motorola had already pledged when they bought them. What assurance does anyone have that Google won't do the same again?
I think you're making a mistake that I see over and over again here on HN. Not my data, not my article. I just submitted it here.
Apple and MS don't like legal uncertainty and additional risks in choosing technologies. Open never entered into it. People also forget some of the problem both companies had with MPEG-LA.
Thanks for the feedback, I too used to use backup buddy, but found this way the quickest for deploying different branches to different sit-ups, an example would be dev/staging/live.

I agree it could be overkill to version control the full Wordpress install, but I prefer to have instant roll back if a update goes wrong.

Can backup buddy now deploy a backup via ssh? For locked down servers
To build intuition, let's consider a hypothetical society. We divide a group of people in two. The first group rolls a die with 100 sides labeled from 1 to 100 in even increments. The second group rolls a die with labeled 1 to 110 in even increments. The roll determines their annual ability level which is unknowable. If you were hiring, which group would you prefer? Is it fair to the second group?

Note that this isn't strictly equivalent for several reasons. The game above the error is part of the generating process instead of the measurement process. Also the distribution is district rather than continuous. The key commonality is that a weak predictor at an individual level can be a meaningful predictor at a group level.
If it starts to rely on systemd, the question you should be asking, is: why does this program want to depend on systemd?

It's to interact with the lower plumbing - ie. set up hostname, locale, timedate, multi-seat etc.

If these interfaces are missing, the software should still work minus a few missing features. Applications could still #ifdef all they want to make things work on BSDs, no change there either.

Or the BSDs could make their own implementation of the plumbing interfaces. Lennart even provided a handy chart:
http://www.freedesktop.org/wiki/Software/systemd/InterfacePo...

Honestly, it's about time we standardize and stop wasting time on these low-level things. I'd rather work on software higher up in the stack, than wasting my time working around trivial differences between the Linux distros (bonus points if they get adopted on other the BSDs too). But that's just me.
"that's what happened"

It didn't just happen - seems like you have intentionally copied someone else's idea, down to naming and design. You're obviously entitled to do so, but it's not something I would run bragging about on hn, especially without giving any credit the original work.

And saying "I don't see a problem here" after the original creator has pointed (quite gently) to the fact, is not very empathetic of you.
I'm kinda intrigued by the way different settings for different domain are handled. I'm using the following approach:

>If there's a dense line in there, how come it's not sticking out of the blob even a little?

It is. If you look at the density in the upper right of the cloud, it is clearly clustered around the x=y line. The correlation may not be very strong, but without extra information about how strong of an effect would constitute clear evidence in favor of including the value add metric, we can't say anything more about it.

> Do actual phenomena often yield "deceptive" blobby scatterplots with dense lines hidden inside them?

Absolutely. You're looking at a misapplication of a plotting technique - a scatterplot with substantial overplotting. The author may be convinced that there's no correlation there, but by presenting this plot they provide no evidence in support of their point.
The problem is people who would have the experience / knowledge to really make it better, are not tempted to go in and fix it, because there's so much political / non-technical work involved in doing that. If someone wants to solve hard computational problems, they might as well go into another field. If they really care about doing biology, chances have been that they aren't the greatest programmers (I understand this may be changing, but still seemed to be the case 4 years ago when I left bioinformatics). This leaves the people who are happy with the status quo, staying in bioinformatics, and the people who are dissatisfied, going to other fields where they feel their work can have more of an impact.

In my experience, what happens is that biologists define the science, and they depend on the computer scientists / engineers to implement solutions to their computational problems. The computational people depend on the biologists to validate whatever results they produce. The iteration cycle can be painfully slow, especially for people used to telling machines what they want them to do, and getting results immediately. The proposition of changing that dynamic is not alluring to most people, but I still hope there will be some who try.

A heatmap would be more revealing, but I'd eat my hat if it weren't a standard distribution (and I had a hat). It's nature (but hey, anything's possible). The scales are only slightly skewed, but we're not talking logarithms. The merit of the scales ("value-added") on the other hand, is very questionable.

But the relation, whatever it is describing, is pretty weak since the ellipse isn't very irregular (it's only "slightly" irregular).

The idea would be not to waste numerous resources and money implementing a broken idea and spend some time coming up with a better one. Why put the education of our children and the careers of good teachers on the line with such a poorly thought out and half-assed idea?
There is no objective way to measure teacher performance. Any evaluation method that can be written as a list of rules can and will quickly be gamed.

The thing is, it's easy to find out who the best teachers are. Simply ask the students, parents, and staff. They all know who the good ones and the bad ones are - and that can't be gamed.

So are indie games, notgames, and Minecraft all not real for you? Reserving the term "modern games" to only "ridiculously expensive projects" and dubbing the rest "not real" is... just one point of view.

What's interesting to me is the fact that makers of indie and notgames, that do not require the enormous scale and pushing the hardware and programmers to their limits - they often make them for Windows, too!

Why You Never Truly Leave High School
Ooh, that's neat. I use a similar system, though mine permits several possible ways to encrypt a number and I usually pick an encryption with 5 or 6 digits. It doesn't require me to remember anything but the algorithm, so I don't feel comfortable with sharing it. I know it might be less secure than encrypting the pin with another pin, but I can't trust myself to remember any pin.
Is this created by a third party based on own design ideas,
or is this by a third party, based on ffOS design guidelines (do they exist already?) or is this published by mozilla?

It looks really great, but those were some questions that came up in my mind when I saw it. It never hurts to have a bit of description on the page.

Huh? The averaging doesn't give you only the positive correlation. It simply averages it. If the correlation was negative, you'd see that just as plainly. Averaging doesn't change the trend -- it just removes the volatility from the graph and makes the graph more readable (what's the density at y=x? I suspect it's a lot denser than he'd have you believe, but you can't tell from the chart at all).

Sure, you could add a volatility measure as well, but the trend is clear -- you'd rather have your child by a teacher with a high teacher score than a low one. Or are you saying that over 12 years of schooling you don't think you'd have any preference having your child taught by teachers with a score in the lowest 5%ile versus a teacher with a predicted score in the top 5%ile? Of course there's some volatility, but over time, it's seems pretty obvious to me.

When I crafted my MIPS subset dual core CPU in a senior design class, I chose the 6502 method. That is, perform ADD, OR, XOR, etc in parallel at word width (that is 32 bits x the number of operations) and select the correct output using a multiplexer. The 8085 method seems smaller but I wonder how much delay it adds to the circuit.

Do I get it right that he is suggesting expiring emails?

If so, then it's a neat idea, but it won't see any adoption. Virtually all time-sensitive emails are of promotional nature, so it's in sender's best interest to keep it in the Inbox even if the actual email content is no longer valid.

It is a great time to be a web developer! I have no idea whatsoever if Firefox OS will gain enough of a stronghold to be a viable competitor in the mobile space. I have high hopes, however, that it will spur the technological advancement of HTML-based mobile apps (aka hybrid apps).

Today, hybrid apps are kind of second rate applications. Facebook (on android?) was the most prominent case, but examples abound, where the UX for an hybrid app is leagues away from a native alternative. Better foundation (frameworks/OS support) can change that, and one must applaud the unification of development stacks.
Did you ever run the HDL on an FPGA? That is half the fun/battle/frustration! =)

Way too involved in your team's day-to-day- I'd say that's a pretty big issue. When you hire a designer to design, and you're telling them where to place things and what they should look like when you yourself have no background in design, that's a sure-fire way to bring a company down
One reason is just that since game development is mostly all windows based, new programmers learn to use windows tools.. and thus become more experienced with them and not wanting to switch to something completely new which would require a loss of productivity.

Also, and that's really only based from my experiences, it seemed to me that game developers aren't that much into "hacking" linux. Things should just Work. The terminal is a deprecated tool compared to new intuitive IDE. Most of you won't agree with these statements (And I clearly don't) but that's really what I've felt every time I'd talk with a game developer friend or colleague. And, this mentality goes back to when I was an engineering students.. While I had fun learning linux and Python, friends graduating in video gaming would laugh of Python for being a "scripting non-performant language" or they would play around in visual studio with C# and making forms or build some games with XNA.

So, sometimes I think it's not that much about linux not being "good enough" but more about video game developers' mentality to not fit with it. Man, I won't lie, I'm an experienced Linux developer and user and I always have to lurk in all kind of forums and RTFM on every small things that needs to be installed (which is not in the standard library). And, it often happens that I break stuff and spend countless hours trying to fix it. Hell, even last week, I've upgraded a server on Archlinux and it totally broke my system without any warning. I really needed help so I went on #archlinux and I've been told that I should have read the archlinux news before tempting an update. Fair enough, I guess.. but I can understand that on a extremely tight schedule, games developers can't waste time on stuff like that. Compared to say, [next] [next] [finish] windows install where everything just Work.

Please, don't down-vote me if you don't agree with things I've seen from my experience. I don't agree with it neither, but I thought I'd share it here. It's really something I see coming again and again from all kind of different video games programmers.

I think the big difference here is that quantum theory and string theory hold enormous implications for the nature of reality. Understanding these concepts, even on a basic level, ignites in us a sort of spiritual fascination with the universe. That's why they are sexy. It has nothing to do with science fiction novels. It's just that understanding the mechanics of a vacuum cleaner doesn't leave us in awe of the universe.
What bugs me about stuff like this is that there will always be mercenaries, guys just like you and me that will do anything as long as it pays. The Chinese government wouldn't stand a chance if they had to do this stuff themselves. Mercenary coders are nothing new, we have them in every country (and sysadmins, companies and so on).

But you have to wonder what goes on in their heads, what mindset would prompt you to sell out like that.
More and more, people think that nannying is the essential function of government.
I see that they're using data-* attributes for a number of these controls- is there associated code for these as well? Markup is great, but a rich control model is more critical for creating great mobile experiences.
I believe that a serious study of kanji (such as Heisig) is best left for a more advanced level of Japanese. Beginners often overload themselves trying to learn thousands of kanji when they don't even know the meanings of the compounds that the kanji are used in. I believe that Heisig even mentions in his introduction something to the effect that using his book won't really improve your Japanese, it will just improve your ability to learn Japanese. Rather than spend hours per day studying Heisig for months, I would recommend a more traditional approach to beginners of learning the most common kanji as they learn the vocabulary.

For the advanced student looking to master kanji, then a method like Heisig's seems best. However, for those interested in the Heisig method, I recommend this book: Kanji ABC [1]. It is similar to Heisig's but organizes the kanji so that you learn similar kanji together. Also, while Heisig spends much time trying to get you to memorize convoluted association sentences, Kanji ABC simply gives you the radicals (similar to Heisig's 'primitives') and you build your own association sentences.

> It seems like you listen to a lot of the propaganda used to separate people into classes that keep them believing that they shouldn't even try.

In the earliest human societies nobody was more entitled to the worlds natural resources then anybody else. According to Heckewelder in Iroquios society "whatever liveth on the land, whatever groweth out of the earth, and all that is in the rivers and waters, was given jointly to all".

Classes emerged when one group of people decided that they were more entitled to the Earth's natural resources then everyone else. These people made these natural resources into their private property and in order to get wealth out of those natural resources they made human workers into their private property as well. These owners became the ruling class and their subjects became the slave class.

Slavery existed in human society for several millennia until it was partially replaced by feudalism. In feudal societies, there was still a ruling class that controlled the natural resources and violently suppressed anyone who opposed them, except that their serfs had a little bit more autonomy and they were tied to the land rather then their masters.

The industrial revolution changed everything. In industrial societies people were able to work in other sectors of the economy besides the primary sector, which allowed some people to live free of the tyranny of the landlords. However, new forms of private property emerged corresponding to the new sectors of the economy. In the manufacturing sector, there was private property in the means of production and the instruments of labor, and in the knowledge sector there was intellectual private property.

The private ownership of our natural resources also still exists. As an example, Gina Rinehart, the world's richest woman, is a mining tycoon who inherited her control of Australia's natural mining resources. Classes have existed throughout written history and with people like Gina Rinehart they apply today as much as ever before.

> Open Source Everything

You want to eliminate the form of private property that exists in your sector of the economy: intellectual property. This is good, but what are you going to do for people working in the primary and secondary sectors of the economy? Do you want farmers to continue to subjected to the tyranny of the landlords and do you want for manufacturing workers to continue to be completely alienated from their workplace?
