If there's one thing I wish I could do to improve HN, it would be to detect this sort of middlebrow dismissal algorithmically.

Unsophisticated people read an article like this and think: Gosh, I better eat honey for breakfast! People a little more sophisticated think: Hey, this is anecdotal evidence! Yeah, we know that. But is that the most interesting thing one can say about this article? Is it not at least a source of ideas for things to investigate further?

The problem with the middlebrow dismissal is that it's a magnet for upvotes. The "U R a fag"s get downvoted and end up at the bottom of the page where they cause little trouble. But this sort of comment rises to the top. Things have now gotten to the stage where I flinch slightly as I click on the "comments" link, bracing myself for the dismissive comment I know will be waiting for me at the top of the page.

> But they all support swipe as well, if there's an issue with the chip (or if you put the card in backwards so it can't read the chip, and repeat until it gives up on you).

For the time being, as a temporary measure while peoples cards are replaced with chip cards. Swipe is being fazed out entirely by 2015. You're already far more likely to get a rejected transaction or trip anti-fraud heuristics if your transaction is not chip-auth'd.

I run one of the largest WP installs outside of WP.com, and we've seriously struggled with performance issues. Sounds like a lot of this complaint is a WP design/performance issue. If you're looking to be create a WP serving platform, it will require a huge amount of custom configuration, a huge amount of hardware (even with the best caching), regular DB maintenance and reconfiguration, and core hacks. Automattic redirects the core dev when they need something, generally only enough to add their hooks, then they write a plugin, release it to the community, but always keep it a few versions back (HyperDB support for 3.4 anyone?)

The WP core team doesn't write code with performance, scalability, orthogonal design, good standards or any such thing in mind and you regularly hit gotchas. However... if you sign up to be a WP platform, you're kinda asking for it.

Obligatory performance tips:
1. Cache the heck out of it. CDN, varnish, optcode (APC), query caching on MySQL.
2. As has been noted, file stat'ing is massive. You have to have an exclusive install as close to each serving node as possible, even with optcode caching.
3. Core hack - Modify admin comment searching. Does 5 column wildcard lookups across the entire table. Not scalable. (http://core.trac.wordpress.org/ticket/20487)
4. Core hack - Remove content reallocation on user delete. With large user tables, you lose the ability to delete users (core fix pending: http://core.trac.wordpress.org/ticket/19867)
5. Clean and optimize your DB regularly - Old post revisions are a huge gain
6. Add indexes intelligently - WP doesn't include all the indexes you need
7. Horizontally scale your DB (whether through MySQL clustering, or HyperDB + DBs with roles)
8. Tune everything. I've found that NGINX/Apache and Percona/MySQL make little difference, but setting the right config for each daemon makes huge difference.

I just use uWSGI - not sure what the added value for Passenger would be.
He did, however describe the eventual problem: his comments table was larger than what Wordpress's out-of-the-box feature (Recent Comments) was able to sort. He had very overpowered hardware in his custom situation. It strikes me that this was an extroardinary but still within band problem that WPEngine should have eaten the cost for solving OR tell him MUCH more swiftly they couldn't.
if an attacker doesn't have the constituent encrypted chunks and/or the encryption key _for a valid time frame_

This reads an awful lot like "If the attacker has not actually compromised the gateway." After all, the gateway needs to either be able to encrypt the password or decrypt the hash to do its job. That means the gateway needs either the key, or access to an oracle that has the key. Either way, you're compromised.

The data sharding has some merit, if only because it's more difficult to simultaneously steal systems from multiple datacenters. I suppose at some level that becomes a concern, but that's roughly the level where you start hiring people with guns to protect your computers.
That's the definition of a write-through cache, not caching in general.

Also, is it really true that data is always read from the SSD? So if a block is requested that only exists on the hard drive, the data must be copied from the hard drive to the SSD, then read from the SSD--rather than simply reading the data from the hard drive?

We have had zero-downtime restarts (or, as we call it, rolling restarts) since August 1 2012, in Phusion Passenger Enterprise: https://www.phusionpassenger.com/enterprise

We also implement rolling restarts more conveniently than Unicorn:

* There are multiple ways to implement rolling restarts in Unicorn. One of them is by sending SIGUSR2. This makes Unicorn fork off a new master with the same number of workers. However this requires twice the memory usage during a restart.

* There are ways to script Unicorn to make it restart process-by-process, but this requires some effort.

* Phusion Passenger Enterprise implements rolling restarts with a single config option (PassengerRollingRestarts on), and it performs process-by-process restarting so that you don't need twice the memory usage. It automates everything for you.

* The "deployment error resistance" feature, which can be used in combination with rolling restarting, ensures that in case your new app version doesn't start, it keeps the old processes around until an administrator manually tells it to restart again.

There are many other features in Phusion Passenger Enterprise which Unicorn does not implement (e.g. live IRB console), or that we implement better. Take a look, you may like it.

We are flattered that you like Unicorn. Being Unicorn contributors ourselves, it's always good to see people contend with technology that we've contributed to. :) Phusion Passenger 4 is the combination of all the experience that we've built up in the past few years, in both Phusion Passenger and Unicorn.

That Stack Overflow post doesn't refute John Graham-Cumming's point, which is that the cryptographic strength of a salt doesn't change the security of a secure password system. The salt is there to randomize the hashes; it doesn't resist active attacks. People that obsess on the security of their salt values misunderstand the design of secure hash systems.

Bcrypt is demonstrably more secure than SHA-512. You can look to the Openwall GPU password cracking project for illustration of how. It is easier to speed up SHA2 on a GPU than it is to speed up bcrypt. Scrypt is markedly different from SHA2; it's designed specifically to be difficult to optimize with GPUs (a property bcrypt has only accidentally at present).

Moreover: the best practice for using SHA2 as a password hash is to use PBKDF2, which is not simply iterating SHA2 (you can learn more about PBKDF2 on Wikipedia). Iterated SHA2 is a fine answer for existing applications that need the simplest possible path to something better than a salted hash, but it's not a good answer for new designs.

Your responses to both these points appear to be materially wrong.
FreshDirect has a 2 hour window, that's not that bad. I usually pick the 6:30-8am window, (I normally wake up at 6:30 and leave at 7:30), so worst case I'm only a half hour behind schedule for work.

uWSGI requires another daemon which you must manage. With uWSGI, you must configure Nginx to forward requests to that daemon. Phusion Passenger fully integrates into Nginx so that is no longer necessary. With less moving parts, there is less system administration overhead.
Out of curiosity, where are you located?

Edmonton I'd say > 95% of retailers are chip-and-pin. Every other place I've been is about the same. Which given that there's two years until they turn the legacy swipe system off entirely, is about where you'd expect everywhere to be in the transition.
My girlfriend was selling at a craft fair recently, and I bought her a nice pair of earrings from another vendor who used Intuit's GoPayment system, and honestly I probably wouldn't have remembered to come back once I had cash (if I'd even gone to get any). In that sort of environment, the standard is 'cash only', so adding Visa/MC to that is a bonus, not a drawback, and in my case it made her a $60 sale she wouldn't have otherwise had.

This is especially true for higher-ticket items like silver jewellery, where I'm not likely to have $60 kicking around in my pocket, but I'll have no problem putting $60 on my Visa. Personally, I also find it hard to part with $60 in cash (more tangible) vs. putting it on my Visa or debit card.

For actual businesses (like bigger food carts), a proper 3G bank terminal is probably the appropriate response, but in places where people aren't likely to expect any card use at all (smaller food carts, craft fairs, yard sales), having Square (or similar) is a net positive.

May do flashy things to get attention, and that's not even positive attention as evidenced by this post, so at the end of the day they must do it for themselves because it'd be easier not to do it at all. I don't know what makes someone a 'poser' and someone 'legit'; what legitimizes their existence isn't appearance, what they practice or what they've been through. It's still a blanket statement of assumptions that doesn't need to be perpetuated.

He's confused, he thinks he's facebook's customer. Facebook's customers are its users. Keeping the uexperience up is the first priority.
Facebook has put themselves in an ideal situation. We're at the point in social media marketing that businesses can't survive without one, in fact they spend a lot of advertising money and placement in advertising their presence on Facebook, which is primarily an advertisement for Facebook. Every new connection, time on site, or new user to like your page is a huge win for them.

Do we as business and individuals really want to pay to promote our content AND be sold to advertisers AND build their network at the same time?
Thanks!

I didn't find it too difficult to setup uWSGI, but I can see how it can suck if you have too many apps, or apps of different types.
I'd say they're probably following a product roadmap that was laid out by Jobs and Cook prior to his death. Apple has been working to where Cook thinks it should go for a long while now, unrelenting progress in maximising, and increasing the efficiency of, the supply chain.
Nope, at this point, we don't take any percentage or fee. We even pass along any discounts we receive (we get up to 15% off flower some purchases for example and we pass that along to you).
May as well throw in my own experience with WPEngine...

We run a relatively small member site (<1000 active members) that operates on WordPress. We tried migrating the site to WPEngine, but could never get the membership plugin working as expected. Over a course of about 2 months we tried everything possible to get it working, and talked with their support on a near daily basis.

Overall, their support team tried to be helpful. They weren't always responsive (sometimes we wouldn't get a response for a day, or we would be waiting on hold for a long time), and we ran into the problem of different support people telling us different things about how their system was setup. Eventually one of the co-founders got involved in the support, but we still were not able to resolve the issue.

I managed to find 2 other people using the plugin that had run into the same problem with us on WPEngine. WPEngine claimed that other customers of theirs used the same membership plugin without any issues. I don't feel they lied, but we clearly weren't alone in this problem.

In the end, we moved to another WordPress host and were able to get up and running in no time. Unfortunately, WPEngine refused to refund us fully for the 2 months we wasted trying to get our site setup because we went past the 60 day money-back period. (We had paid for the 3rd month already, and they gave us a partial refund of that month only.) It was a relatively small amount of money, but after all the trouble we had with them it would have left a much better impression if they would have refunded the entire cost we paid.

I'm sure that WPEngine has thousands of happy customers, and our experience was largely unique, but there are many things I felt they could have done a better job of.

Do you have some data that we could use to play with? That sounds like a nice problem to solve.
Yes, hydroponics produces the best possible quality food that can be made. Being a closed system, it also doesn't require pesticides so it's essentially organic anyhow.

You are correct that Organic produce is the obvious immediate competitor. I wonder if hydroponically grown good can be labeled as organic. it could certainly come with no label at all.

As to whether there's a marketing benefit to actually being labeled as hydroponically grown, I've no idea.

As for subsidies, I assume that Organic food takes advantage of all of the same subsidies as non-organically grown food.
>I had totally expected Microsoft will get Office right

I don't know why you'd expect this. The office team has always been one of the biggest violators of any HIG or best practices guide that the windows team publishes, I find it hard to imagine that a new version of windows will suddenly make office a well-behaved windows app, when it has failed to do so for the last 7 versions.

That's kind of what sites like Service Magic (Home Advisor) try to solve. But, I think their biggest benefit is the user comments and reviews, not their service.

The Sorry State of Game Portability
Ubuntu is nothing but a Linux distribution. The job of a distribution is to provide packages, not dictate to you which packages you must use.

I use Ubuntu because it seems to still be the desktop distro most widely supported by third-party apps and drivers, and I have had good success with release upgrades. Otherwise, if I had any problem with Ubuntu's package repos, there's no reason not to use Debian or Fedora instead. Among desktop distros, Debian stable is great if you think Ubuntu LTS doesn't have a long enough lifespan, Fedora is great if you have a little more experience with Linux and want faster package updates. Both Debian and Fedora have always had more 'hacker cred' than Ubuntu without losing the benefits of being mainstream distros, if that is what you are looking for. If you want even more hacker cred, try BSDs, Slackware, Arch, Gentoo.

Canonical isn't forcing anything upon you or anyone else. They aren't doing anything unethical with Unity's design. Nor is there anything to distinguish your opinion as more worth listening to than others'. As a private company, it is Canonical's choice how they spend their money and try to build market share. You can type 'sudo apt-get install xubuntu-desktop' in seconds. You aren't paying anything for it. And there are really no external forces pushing you to use Ubuntu over anything else. It's just a distribution of packages. Serve yourself however you please - this shouldn't be a problem for you, since you are complaining that Ubuntu has abandoned 'hackers'.
I too have been following these blog posts. I'm happy to see they've open-sourced Druid but I agree that some more documentation and examples would go a long way. Presumably this will be coming in the future, for now it's nice just to be able to grab the code and play.

I find his pricing strategy for the game rather interesting. The game is free to play and contains no ads, but for $0.99, you can upgrade to a "full" version and unlock a few extra features. I think this model will definitely attract a lot of people, but I'm curious as to how many people will actually decide to pay for that upgrade (I did after about 15 minutes with the game ‒ I love it.)
Yes, but the productivity gains from not having to buy TP but once a year would more than be offset by the additional time spend on the can.

You already have the data I'd use: the text of the comments.

If anyone wants to try to train a filter to detect this sort of comment, I'd be very interested to see the result.
I don't know what these people are talking about... Call me crazy but when I saw that I had to pay for this at all I thought "Hmm, couldn't I implement that quickly myself?". Perhaps I could or couldn't, but it seems to me that it would be better served as a one time purchase. I wouldn't want to pay a monthly fee for any other premade component (lightbox, image carousel, etc).

I'm guessing there's some service associated with this, but from the tour it wasn't obvious. I'm not attacking your product, but want to give my experience/thoughts.

"Your summary of Level 5 is not quite right - Level 5 is about storing separate chunks of ciphertext"

Ah, I see. So you generate hash H and using some private key K you calculate C(H,K) where C is some cryptographic algorithm and then you split C(H,K) into parts and spread them around.

So my scenario is complicated by the necessity to compromise K in addition to one of the places where bits of the C(H,K) is stored.

I still feel that the real security of this system relies on the difficulty of computing H.
The speaker obviously had personal experiences involving teenage girls when he was younger, and related it back with a personal anecdote. Calling him (or the analogy) misogynistic is incredibly loaded, and seems more a knee-jerk reaction to anything that depicts one gender negatively without simultaneously doing the same for the other than a real critique. The use of the word 'thought-crime' was quite deliberate.

Save the outrage for where it actually matters - there is plenty of real misogyny out there. Just today I read a story about some idiot candidate for Senate in Indiana...

I really hope you don't have to pay $1,300 to get a 768GB drive in your system. I ran into a situation a couple years ago when the 320GB drive in my MBP was running out of space. I didn't want to buy a whole new system, so I ordered a 640GB drive online, took it to a local certified Apple repair shop, and let them put the drive in. The cost of the work? $100.

This was before the unibody models, but I'm sure the process will be the same for the new systems. Oh, and the best part of going to an Apple repair shop was that my warranty remained intact. I never had any issues getting the Apple Store to work on my laptop after the hard drive was replaced.

If Apple prevents people from doing this with the new hardware, then this will be a disappointment. I haven't kept up with the specifics of their new laptops--I know that the RAM is soldered in, but I hope the hard drive will be replaceable.

I'm more curious what VPS package you had powering your stuff at Linode and how much you were spending on it each month? Reason being that 250 USD buys a LOT of server these days and it is surprising you ended up with underpowered hardware if your VPS wasn't giving you any problems.

If you're looking to upgrade in the future, you might be much better off throwing a dedicated server at the problem and setting a nightly backup to S3. Also, thank you for posting.
