Based on this comment, I started looking into JRuby support for the pg gem. I think it's possible; I have started stubbing it out, and the Postgresl JDBC driver publishes additional interfaces that provide everything folks here have been asking for.

I'm looking for help filling it out. Here's the mostly stubbed extension:

https://github.com/headius/jruby-pg

And here's the docs for pgsql's hidden interfaces (cast the JDBC objects to these, and you're good to go):

why most of the games emulate Mario? I am not a gamer, but for me, the first impression appears to be like mario...though the plot and creatures are different.
I'm seeing a lot of these type of comment. The thing is, AWS completely crapped out. Don't believe their status updates that make it sound like it was a tiny little area of their data center. It was pretty much the entire zone and then whenever there is an outage affecting an entire zone it brings down global services and even other zones as well.

We had servers in the bad zone and started having load issues. When I went to use the cool cloud features that are made for this, the entire thing completely fell on its face. I couldn't launch new EC2 servers either because the API was so bogged down, or the new zone I was launching in was restricted because of load.

Basically, the thing that nobody keeps in mind when they think it's so cool that you can spin up servers to work around outages is that EVERYONE IS DOING THAT. This is Amazon's entire selling point and when it comes to doing it, it doesn't work!

We were lucky to get some new servers launched before the API pretty much completely went down. They started giving everyone errors saying request limit exceeded. The forums were full of people asking about it.

ELB, Elastic IP, and other services not associated with a single availability zone completely failed. I keep seeing comments saying that if people designed their stuff right, they wouldn't have an issue. That's just completely bull, AWS has serious design flaws and they show up at every outage. It's NOT just people relying on a single zone.
Well, comparing Apples and Teslas ;)
Long time indie game developer here; if you're looking to make money from this, you need to have the demo playable directly on your website.

A back of the envelope calculation suggests that serving the game even on S3 would cost $2 per 1000 players - much less elsewhere (I use 100tb but that's overkill for you).

I don't know if you're keeping track of the conversions - from hit to download and hit to sale - but you should easily make $10 per 1000 hits. $3 is also too low; you're likely to make far more revenue at $5 or $7.

I wouldn't be surprised if this change alone raised your revenue by ten times or more for people not coming from the ultra curious HN crowd.

You also should make the intro more like 10 seconds long at most. Split the intro cutscene up and show it slowly over the levels.

Seriously. You need to do this. I guarantee you're losing at least half the players.

Some other notes from a quick playthrough:

* Shadowing is impressive!

* You should probably scale 2x by default. Full screen is too big and default is too small

* I love the premise of the story

* You should have a visual reaction when you're hit

* Sticking in the same direction as you're firing works but I would limit it to key down, not key hit - let the player turn as normal when they tap fire

* It would be awesome if stalactites fell when you shot them, able to take out enemies

* Unfortunately I closed the game accidentally having gotten this far in the list and couldn't bring myself to button mash through the intro again :)

One last thing; I understand that it's the end of a long project and you just want to get it out. But the hours you spend to get the launch right (marketing, testing, feedback from friends etc) are critically important to the success of the product as a whole.

They're easily worth 10x as much to the bottom line as the hours you spend hacking away in the middle of the project. Single changes can have a 20% or 50% or 100% impact on sales.

I wouldn't try to release quickly and barely test a project I've been working on for two weeks, let alone two years - something to keep in mind so you don't have to learn it the hard way like I (and many others here) did.

In any case, great first project! Do you have a mailing list to sign up to? I'd be interested in hearing about whatever you come up with next.

I will be happy if someone corrects me but JDK 7 has some bugs with InvokedDynamics and it is turned off by default. These bugs have been fixed in JDK 8 (beta so far).

In the future, even if JRuby team does only bug fixes, JRuby will get faster and faster as JVM's support for dynamic languages improves through InvokedDynamics.
I think many people here are confused as to what constitutes "stuff".

In your example, you find your box of bits and tools extremely useful and they make your life better with essentially zero maintenance cost or ownership burden. They take up very little space, and are not big and heavy to move with you.

This is not "stuff" these are valuable things in your life. Keep them!

"Stuff" are usually physical objects you have that probably get a tick in one or more of the following boxes:

a) High cost of ownership (monthly fees, or regular maintenance)

b) Requires payments just to keep/use as intended (still paying it off / satellite radio fee)

b) Big and / or heavy. They take a lot of space to own, and to move with you.

c) You use them infrequently, and don't particularly get enjoyment when you do (the "good" wine glasses for example)

These items you can remove from your life, and you will be happier for not having them.

Bloom filters in redis: https://gist.github.com/3936629

Turns out it's kinda hard to get a decent hashing algorithm working in redis-lua-land, but I'm sure an implementation of murmurhash wouldn't be so hard if one had a few hours.

EDIT: It's worth mentioning, too, that we've been using a collection of lua scripts to manage inventory reservations at Shopify since March, and the tech has worked very well for us.
I run ubuntu 10.04nbr on my eeepc off of an sd card. It varies between truly awful and not that bad, depending on the particular card I'm using. None of them are top of the line cards, mostly Transcend SDHCs of various capacities. The 8 gb one works well, one of the 16s is ok, the other is crap. The higher speed, larger cards are optimized for throughput, not random writes.

In the ok range, I could get work done-- chrome, emacs, and a web stack running. Page loads revere slow, but usable. I don't think I'd set a machine up this way again, it's just too much of a pain for what I'm getting out of it.

It's complicated. Wayland can replace some parts of X11 in Linux distributions, but it relies on some other parts of X11 (like libxkbcommon).

I believe Wayland window managers [1] will replace most of X11 for most users in a couple of years, but X11 will still be around to run legacy apps (similar to the way you can run X11 applications in

I also think that Wayland will replace X11 in the way that most of the X11 developers will move to Wayland. X11 will still be around, and probably still be supported by window managers for quite a while though.

1. Wayland is actually the protocol/API, which window managers/compositors and the applications that run in them will implement. The reference compositor for the Wayland project is called Weston.

It's easy to understand shooting a leg with a shotgun. That's a simple thing.

The Amazon thing in question is far more complicated, and far harder to understand.

Thinking they are "akin" is a mistake. It shows you're thinking about it wrong and failing to recognize how completely different they are.

One isn't going to confuse anyone or be misunderstood, the other will confuse most of the population and be misunderstood by most people.

One, if someone misunderstood, only involves one individual being an idiot. The other involves a large company being evil and thus can help feed conspiracy theories.

I'm not sure if you are aware of the difficulty of Amazon doing this. Suppose Jeff Bezos wants to do it. He can't simply order people to do it because they will refuse and leak it to the media and he'll look really bad and then he'll definitely have to make sure to try super hard for there to be no outages anytime soon.

Shooting yourself in the foot is stupid but easy. Doing this is stupid and essentially impossible. To think it's possible requires thinking that Amazon has a culture of unthinking obedience, or has an evil culture that all new hires are told about and don't leak to the media. Totally different.

Casually talking about impossible, evil conspiracies by big business, as if they are even possible, is a serious slander against those businesses, capitalism, and logic. Slandering a bunch of really good things -- especially ones that approximately 50% of US voters want to harm -- and then saying "it's just a joke, it's funny" is bad.

While "luck" (especially the sort that leaves you relatively healthy) may be considered a factor in any business endeavour, I think it's worth pointing out that most levels of business success require several orders of magnitude less luck than a successful startup (of the "enormous growth" variety) does. That may be obvious (and in fact it follows pretty directly from most definitions of what constitutes a startup IMO) but it's an important distinction; many of the people reading this could create a "lifestyle business" with an excellent chance of "success" by the normal definition.

I looked through the comments and was surprised that mostly there seems to be a discussion on if we should legalize it or not...

I was mostly intrigued by the principle and the layout of the site.

In todays time it seems like an awesome principle to just make a collection of noteworthy people and get people to twitter (generally: contact) them to get their point of view in order to use this quote for your cause.

Combined with a nice layout, catchy URL and clever use of social media, seems like things like this could be done with more causes than just this one.

While i know that most of you will think "Well, not really a revolution, it has been done before. Where have you lived the last few years of your life to be intrigued by something like that" I personally never saw it in such a well executed form and manner.

How about doing the same with gay marriage.

So this seemed insane to me. SSD stalking has become a bit of an obsession of mine, and the thought that an SD card could beat out an HDD was hard enough; that it could beat out an SSD bordered on blasphemy.

But it has proved to be plausible. A gloss for those in the same boat as I was:

I just did a "hdparm -tT /dev/sda" on my bluelight-special 5400 rpm laptop drive and it is getting 3,100 MB/sec cached reads. The absolute fastest reads I see reported with the Sandisk Ultra cards on Amazon is 45 MB/s, with a few 30 MB/s reads, and mostly 20 MB/s reads.

Something doesn't add up here.

But the thing that really matters for bootup time, application load time, and application responsiveness time is 4k random reads. And 4k random reads for my bluelight-special 5400 rpm drive are:

4K random reads: 494 KB/s (KB!!!)[0]

According to the number one google result for "4k random read sandisk ultra"[1]:

4k random speeds: 4,499 KB/s

There are definitely some older SSDs that come in at around 2,350 KB/s (6,000 iops) for their 4k random reads.

So moral of the story: just buy a new SSD already with 4k random reads of 250,000+ KB/s.

In addition, their comments about Core Data multithreading are flat out wrong. The whole point of queued contexts in iOS 5/OS X 10.7 was to do away with the whole mess of passing IDs between threads. It works quite well, although as always, there is a vocal minority who never completely grokked Core Data and hate on it when they encounter bugs in their implementation along the way.
Please don’t even call out to the server, unless I actively interact with the page. I sometimes open 50 or 60 browser tabs at once, and when I unsleep my laptop or connect to a new wifi hotspot, many of them try to simultaneously make such ajax calls, which prevents any other web pages I want to open from loading until those calls either make it through or time out. Occasionally I have to SIGSTOP my main browser and open a different one if I need to access something online right away. Even pages of ostensibly static content, like years-old news articles, now are littered with "web 2.0" doodads on them which do this kind of crap.

Constant surveillance is one of those societal boundaries where the line is hard to find. We all agree that public spaces are... public but if a plane can follow everywhere you go and record all of it, you start to get into weird creepy stalker territory. If that plane is controlled by the state then it is doubly creepy.

There aren't easy answers but it ultimately goes back to the 'Why do you need to hide anything if you don't do anything bad?' argument. And we already know plenty of answers to that argument.

There's a huge labor shortage in the software industry, but we seem to be doing just fine. Simply pointing out that the shortage exists does not automatically imply that it's relevant or even useful to correct.

If you will not acknowledge that this course of action could well increase the class divide, or that widening said divide is bad for everyone, there's not much to be done.

(As an aside, why again is it undesirable to simply help them get running water and schools in their own countries?)

More concise explanation of the signal bit: the notion that we can get reliable factual signals out of the current situation does not work, because we can cherry pick any action (or lack thereof) and ascribe to it motivations at whim. Better?

You're statement is actually much more stupid than the verdict. I can tell you have not studied law. You should start with Babylonian law...

https://en.wikipedia.org/wiki/Code_of_Hammurabi

Fortunately for humanity, such principles have been the foundation of civilisation since the time of Babylon. What you think is stupid is actually a part of the foundation of civil society.

I think the loss of principles such as these are a big part of the rot in our society. Take for instance Wall Street. Once there is a disconnection between the actions and behavior of people in positions of influence and authority and the consequences of that behavior, you get an economic moral hazard and the implicit license to do and say whatever pays your pockets for that day, ignoring all the downside risk.

The correct answer the scientists should have given at the time is "yes, there may be an earthquake. Or there might not be. We can't tell." Not just saying what the politicians wanted to hear. Not just putting out a statement to placate people and make them feel safe. That is certainly negligent. This is not an attack on science. This is holding authority to account for their negligence.

Personally I think the case should extend into the negligence of politicians who forced the scientists to release the statement as well. Also negligent may be the builders or building code authorities who allowed such fragile buildings to be built in a high quake area. There is more than one negligent party here.

Also not covered in the article is the fact they arrested the non-scientist who made the prediction and locked him up, because he was driving around trying to convince people to relocate before the earthquake hit.
That's a great post! Thanks for sharing.

Why is the idea of innate IQ still taken seriously if there's so little evidence for it? If intelligence is just the ability to think in a structured abstract way, doesn't it make sense to think of it as a skill developed over time? I mean, it's not hard to think of spending most of your time in a different mode of thought. I'd say that for most people their normal day to day tends to require concrete or social/emotional information processing.

If it seems that intelligence (specifically abstract structured thought) seems to stabilize early in life, maybe it's something that starts developing even earlier. A strategy for prioritizing, filtering, and processing information from a world of endless stimuli (of which abstract/structured would be only one such strategy) would start developing the moment we're born. By the time you're 10, you'd already have 10 years of "practice".
