> For I/O-heavy workloads with a lot of metadata changes - unpacking a tarball was given as an example - Dave said that ext4 could be 20-50 times faster than XFS.

A while ago, I read somewhere that XFS is good for a small number of large files, whereas ReiserFS is good for a large number of small files. I don't know whether that's true anymore if it ever was; but perhaps extracting a tarball with thousands of small files in it is not the best way to bring out XFS's strength?

By the way, when are we expecting the "experimental" label to be taken off of btrfs?
France used to ban crypto back in 95/96 I remember we had to make huge changes to BT's Intranet to disable certain parts of it from collegues in France as we where not allowed to uses encyption to acess via a dialup service.
The issue with mobile is the limited screen real estate and the impact that has on being able to place ads. The mobile environment is different from the desktop environment, so it makes sense to distinguish the two. But you're right, calling the later "web" is a misnomer.

Don't ever start using vi. After you do, any text editor that you are forced to use that doesn't have vi key bindings will give you fits and make you cry.

Learning vi is your standard process of enlightenment and elation followed by a lifetime of disappointment. Think about how you'd feel if you ate the best meal of your life at age 13, and the restaurant where you ate it went out of business the next day.

You'll be frustrated by all other software. You'll wander around trying to explain to other people why the thing you had was so good, and it was so easy, and that nothing else compares, and wouldn't it be great if everyone did things this way.

Exactly like the author of this article.

No, we need a careful investigation of the filesystem.

Listening to my "works fine" comment is as useless as any other "didn't work for me" comment.

What might be helpful is a comment saying "I encountered the following issues with the following configuration, reported the bug, and the maintainers said ..." What would be even better would be for actual experts to audit the code, look through the bug reports, and give their opinions.

But "works for me"/"broke for me" comments are, unfortunately, as useless as most filesystem benchmarks. Indeed, any time filesystem discussions come up, a stunning majority of the opinions are unhelpful. Unfortunately, I jumped right in with one as well :(
Yeah, I also learned about the -i] commands. Can't believe I didn't know about them before...
They even say it's suspicious that someone shields the screen from view of others. WTF? I consider most of my communications essentially private and I don't want anyone to be eavesdropping.
Until the academia realizes that computers can read too, it's important for companies that DO have access to these papers (like google scholar[1]) to create 3rd party APIs so that we can at least have better search tools.

Ask HN: Has a startup ever tried renting out women's shoes?
I was thinking about statistics concerning women's shoes. Most women only wear a pair of shoes a few times. It seems like there would be value in setting up a Netflix like system where women could pick out shoes they want to wear and put them in a queue, the shoes are delivered, and then returned after use. Obviously there would be w number of hurdles to this, the biggest that I can see being sanitation. I'm just wondering if anyone has ever tried.
I always thought that was interesting because on my computer, JFS feels faster than XFS does (especially when using Pacman, on Arch Linux, which creates lots of small files).

Personally, I have never lost data with XFS or JFS.

I use vim for about a year or more, and I like it, however I'm still having trouble with copying and pasting tiny fragments of text. Maybe someone can help me out with this?

1) If I yank a line with yy, pressing P or p will insert the text into a new line.

2) If I go to visual mode and select a region, yank it with y, then press p/P, it gets it inserted into the current line.

That is, vim preserves new lines.

What I can't figure out is how to paste into the current line in the first case, and, vice-versa, how to easily paste into a new line in the second case (without doing :put, or opening a new line).
The feed itself still has a long way to do. I want to try a Timeline feed.

I was confused too. I think (given the counterpoint to the Naysayer) that this could best be described as the "Yes Man".

Incidentally, this article (like Joe Brockmeier's other articles) really needs some good editing, which is disappointing given that Joe claims to be a technology writer and editor.
I'm not sure there is much utility in trying to define "computation" as an intrinsic property of anything in the real world, rather it is a useful property that we can ascribe to particular systems if that proves to be useful.

For example, I once worked for a distinguished engineering professor who told me about he started his career building simulation models of fluid flow using hydraulic analogue computers. Note that they constructed mathematical models of the fluid flow and then solved these using hydraulics - it wasn't an attempt to simply copy the "real" systems being modelled into an idealised experiment. In this case the fluid in the simulation was arguably "computing" in the sense you mean - but there was nothing that looked like a digital computer or a program or even an algorithm.

My experience with XFS and Arch Linux is that it is rock solid.
Not sure about passionate, but I like it enough that I use VsVim for my day job (.net developer).

I actually started using Dvorak before picking up vi; never had a problem with the keyboard mappings. It helps that j and k are still next to each other, and h is to the left of l.
The last time I used AIX (I believe it was 5.3), it had old-school vi on it. I would bet this is true of newer revisions of AIX, as well as other commercial UNIX(tm) systems. I would also not be surprised to learn that some/most of the BSD systems still use it.

So Obama signed the National Defense Authorization act which allows the indefinite detention of citizen and non-citizens declared as terrorists of the united states. Lamar Smith is pushing a bill that will require ISP's to store all information on U.S. Citizens that tie to an IP address. Now the FBI is saying you are a terrorist if you try to hide your ip. So now if you don't allow the government to capture all information about you from the internet you can declared a terrorist which in-turn will cause you to be held in jail indefinitely..... or im just paranoid.

When I used it, I found it had a tendency to zero out files which were open for writing during a system crash.

This was pretty much a FAQ and very much by design. See for example:

For #1, the yy command will yank the entire line (including the newline). Try using y$, which will yank from the cursor to the end of the line (not including the newline).

A good CDN provides "close" (network latency wise) servers so if there are 30 assets to be loaded, most are done over a 10 ms hop, not a 60 ms hop. Get a complex page with 100+ assets, or try to serve it to another continent and the difference is even more impressive.

Also if you're running a "busy" site off one server, it may not be busy enough to warrant a CDN's traffic off-loading perk. When you start talking about thousands and tens of thousands of requests per second, being able to off-load 80% of those requests makes a huge difference in how much hardware you need to deal with locally.
For the first, you need to do a 0yt$ .. this will yank to endline, but not include it. The whole line can then be pasted into another without breaking it.

The 2nd can be o/O<esc>p .. Maybe there's a more elegant way though!

You could bind these to, say, <leader>p and <leader>P, if you find yourself doing it a lot.
I think it is all about intention. Intending to kill innocent civilians is different than accidentally killing them while trying to target enemy combatants.

(Of course, these differences mean nothing to those who were wrongly killed.)
That's no problem until you want to list all lists of lists that do not contain themselves.

There are some video tutorials by Derek Wyatt that have been recommended on HN a few times:

http://www.derekwyatt.org/vim/vim-tutorial-videos/
:h i_ctrl-r

That is, i<C-r>0 will paste a line character-wise, but the EOL will still be there, so you might have to join lines afterward. Alternatively, you could not yank the EOL with ^y$.

For making a newline with a character-wise yank, use o or O to make the new line and you can use <C-r>0. Or Escape and p.
Whether it pastes a newline or not depends on whether you yanked one. I guess this is what you mean by "vim preserves new lines". Don't all editors work this way?

If you want to yank a line character-wise, you would do something like ^y$. I have Y mapped to y$ for this sort of thing.

You cannot yank a substring of a line line-wise. That doesn't really make sense. I typically open a new line with o and then paste in insert mode with <C-r>". So o<C-r>".
For the first case: use 'J', join-lines command. It deletes the newline at the end of the line your cursor is on.
Well, the awesome Yvain (aka Scott Siskind) must be mentioned here, since he made years ago a list of lists of lists of lists.

I used vim for about 9 or 10 years before I switched to emacs. From my perspective people use vim because they haven't tried emacs yet (I kid!).

I still have the muscle memory for vi and that's what these sorts of editors rely on to be effective with them. Once you get enough practice the editor practically disappears and it becomes more about the text on the screen... almost like you are manipulating it directly with your mind.

Fun article. :)
I'm not sure how a tool to read some text and display a diagram of the chemical reaction described falls under the "law" of the quoted passage. Copyright law certainly allows for this, so all the journals can do is say, "you don't get to buy our feed anymore if you run your program on our articles," but surely this is a game of chicken because no company wants to lose tens of thousands of dollars a year for no reason.

I would implement this as a browser plugin that uploads the content to a server (like Google Translate), and let the journals deal with each rogue user individually.

Telling people what software they can use to read text doesn't scale.
Hahaha. That's pretty much /thread, innit?

Google counter-censorship: Why does my blog redirect to a country-specific URL?
Related question: I started playing with mod_pagespeed when it first came out, however at the time it was very buggy and broke RichFaces based apps, PHP Gallery, and a few WordPress plugins that sites I host run, so I had to ditch it. That was ages ago though. Has anyone been running a recent version of it? What is your feedback?
That doesn't matter. There is no law nor any court ruling even in France against providing free services. Here is the entire key to the issue:

>Bottin Cartographes argued that Google was only planning to give away the service for free until all the competitors had been driven out of business and then they would start charging.

It's not about free services, it's about willfully plotting to gain marketshare via free services with specific intent on charging for the service once the competitors have been driven out. While I believe the French ruling is faulty (where is the proof?), this isn't an issue of free vs paid.

The analogy only works if Wikipedia has specific intent to begin charging for access once your business is gone.
Not exactly marketing, but: I gave one to my mathematician girlfriend last year, and she pointed out that adding a lock would make these necklaces much more flexible ("nontrivial knots").
It's not the semantic interpretation of text that they're banning, but the scraping of text, which deals with copying what they'd prefer to sell you. Still an abhorrence, but let's get our facts straight.

You do realise you're actually arguing against your own point 2 up?

You said the reason the small traders went out of business is price, but now they suddenly shouldn't differentiate on price?

You don't really seem to understand monopolies or free markets or how they operate.

1. Monopoly emerges
2. Competitor opens
3. Monopoly slashes prices in local store, while maintaing prices in all others
4. Competitor runs out of cash, closes
5. Monopoly puts prices back up

That's how it works. You can also replace 3 with 'Monopoly slashes prices everywhere and relies on its cash reserves'.

But hey, you ARE French, of course you're right. The same thing of big chains killing all small towns isn't happening in the UK too for example. Oh wait, it is.
There's no good way to do it, unfortunatly. You need to yank the contents of the line without yanking the entire line qua line. Now, if 'l' were a text object for 'line' then there would be an obvious 'yil' for just getting the inner stuff, but since there isn't you'll have to do
0y$
to go to the start of the line and yank until the end of the line. That'll store the line contents instead of the line itself, so p will do what you want it to.
Interesting article, I have always been interesting in moving to Vim, and this article all but sealed the deal for me. The only problem being I don't really see how useful this would be for general notepad usage. I understand the author of this article is selling his plugin for Visual Studio, and this is a marvellous way to do it. Is there any other way to integrate vim with Visual Studio 2008 without purchasing his ViEmu? I would love to start learning vim but I doubt a trial would be enough, and I don't see most of the other attributes he covered ('.' for example) being very useful in daily notetaking.
> Actually, this kind of law does not make any sense. In the case of carrefour, since they are charging such high prices nowadays, what prevents a bunch of farmers to associate themselves and open their own mall to sell cheaper and regain market share?

The knowledge that the big mall will simply temporarily lower its prices below what the collective could reasonably do (due to their lower size/efficiency) until they're dead, and then re-raise them again?

I see it like shoes. You wear Nike, your friend wears Adidas, but you can still walk together. You can connect across networks, tag photos across networks, etc. You will have your personal page but it's really just a place to rest your head - your 'Newsfeed' aggregates all your friends activity from whatever network they're on. It won't matter what shoes you wear, just get a pair and go walking.

I know this will be an unpopular comment, but my whole problem with it is actually the attitude of those that use it. After reading the article, I was really impressed and imagining all the ways it could help me after what, 8 years of coding into an IDE; and then I got to this:

"Do whatever you want. Don't learn it if you feel it's too much effort just for nothing. Learn emacs instead. Or stay in your IDE using a lousy editor. Whatever. But in any case, don't ever claim again that those 'vi guys are nutheads' - I hope that I have succeeded in showing you why they (we) stick to it, and you should at least be able to understand its power, even if you prefer to stay away from it."
