Yasmine, I'm so glad you published this story.

It's incredibly disheartening when anyone who lives in the United States believes that they are poor. Too many people born with the privilege of being American citizens choose to blame their life on outside circumstances, when the reality is they've been given the best outside circumstances anyone could ask for. Many people want to redefine the American dream as some kind of struggle for subsistence, but you've perfectly exemplified the true American dream: if you're willing to set goals and work your ass off, then you can choose what kind of life you will live.
Sure and thats usually a reasonable thing to do these days when storage space and bandwidth are pretty cheap.

It was really just an observation that 12 floppy disks isn't really very much. I guess random observations are downvotable offenses on HN, but thats ok too.

what is the "knapsack algorithm" ?

I understand how arranging images may be a "knapsack problem" but I can't pinpoint what the algorithm is supposed to be.

Great idea! However, the term "knapsack algorithm" is quite misleading.

There is the "knapsack problem", but there are various different algorithms to solve it. Which of those has been used? Why this and not another algorithm? All those questions are concealed behind the squishy term "knapsack algoritm".

Hi! I am the author of the plugin. Thanks for the issue. Creating an example for you guys right away :)
Whipped up a quick example, it seems to re-order the images in a way to fit the most it can on each row given the width constraints and the width of each image - http://jsfiddle.net/vXbCY/
Sounds like they have you under their spell..

(but seriously I'll probably check out those sites now : P)
There is a similar guide to hangul with information arranged in the shape of the periodic table of elements, the "periodic table of hangul": http://www.aboutletters.com/pfaq.html. I found it to be a reasonably handy reference that logically compiles all the information in one image as opposed to this guide's gradual introduction of vowels and consonants mixed in batches.

The author no longer authorizes distribution of the image over the internet, however copies can be found with a google search.
Disabling dynamic paging as suggested in the fine article seems to have made some apps that constantly gave spinning wheels before (Firefox, Time Machine backups) some extra speed.

However, it's still early days. It might just be a "washed car effect."

Computer Optimization Tips – How Can I Prevent Registry Errors Correctly
Registry is a hierarchical database which stores configuration setting for low-level operating system components as well as the applications running on the platform, including kernel, device drivers, services, SAM, user interface and third party applications. Windows Registry also provides a means to access counters for profiling system performance. Because of the importance of Registry, you should fix any registry error at once you found it. Registry error can be caused by many things, such as improperly uninstalled applications; virus, Trojans and spyware; and too many unnecessary files on your operating system. If you’re having problems about registry errors, you should read this article and you will get assistance from here.
Thanks! Mind if I include this on the github link?
At first animated graphic novel sounded like an anime to me. But that concept looks interesting. I am not so sure if it will actually be better. After all, is not an important part of reading a novel, or graphic novel to be immersed in the story and let ones creativity and visualisation flow to make the story a living experience in ones mind? If this supports that, it would be very great! On the other hand if an animated graphic novel would distract from the this, it would be very sad.

I very much like the old touch that it's given and it contrasts great with the new technology.

In the end, if this concept can lure some kids, who'd rather watch an anime than read, to read more. That would be quite an achievement!
We have used Knapsack 0-1 algorithm, since in our case images had different widths but the same height, we wanted to fit in as many images as possible so that they fit in the best way possible. We gave value 1 to each image and weight equal to width and use the total width of container of images as the maximum weight allowed.
Too slow. Pull request submitted :)
Very interesting story - hard to comprehend how frustrating it must be having lived somewhere most of your life without being formally "accepted".

"I can speak out against the government, if need be, without fear of being prosecuted, imprisoned, or killed".

Probably pays not to take that sentiment too far however. This is still the USA we're talking about.
Well I liked it. Might be worth a re-submission when the USA wakes up.

Plugin co-author here: One more possible extension of this algo would be to use value of each image equal to the weight of each image. This would ensure best fit and would be one more way to make things look beautiful and arranged.
Thanks for this - appreciated :)

It was more the walled-garden approach Apple took throughout the 90s that I was referring to. The steps they took to ensure that they were the only ones who produced computers capable of running Mac OS -- moving critical bits of the OS to on-board ROMs; applying government pressure when necessary to prevent the manufacture of early Mac clones which used reverse-engineered ROMs; later destroying the legitimate Mac clone market -- are eerily similar, albeit technically inferior, to the things they're doing today to prevent people from running OS X on unauthorized hardware and unapproved apps on Apple devices.

Apple already contends that OS X can't legally run on generic PC hardware, and has already taken x86 Mac cloners to court over this and won, so they know they've got the law on their side when it comes to control of their OS, where it can run, and what can run it.

The next logical step is to take control of what can run on it. With the recent OS X "virus" scare, the issue has become all the more urgent, as the public's perception of its security has been damaged and a signed-app "solution" seems like the easiest way to restore confidence in it.

As far as requiring signed code goes, though, their other devices already all require it, so I'm assuming, based on their moves so far, that it isn't far off on the laptop/desktop end. That it's an option (on by default) in 10.8 makes me think that, one day, the option to run unsigned code in OS X will disappear entirely.
This is the flamebaitiest flamebait I have ever seen, even accounting for the topic. It is insanely rude and unproductive. I hope it gets flagged into oblivion.

To the author: Respect your fucking readers or don't click "post." Your mother said health care pricing is screwed? Explain and teach me something or don't throw it out there. You have some godawful stereotype of people who complain about the government? Back it up with facts or get the fuck out. Don't feed me some "you are" and "you will" morality play when you invented your hypothetical audience out of thin air. Don't write three paragraphs about your straw man moron without an iota of any actual information besides rambling. Give me a break.

That looks brilliant! Can't wait to read it! Truly inspiring work
The ability of Go to produce a single, self-contained executable is one of the biggest advantages it has over the "scripting" languages. It makes deployment so much simpler.
I agree, but I'll point out that programming has been part of the curriculum in this locality since at least the time my dad was in high school. He tells of writing programs on punch cards. We started with BASIC when I was in elementary school.

Despite that, I don't know of anyone who I went to school with that could write a single line of code today. Of them, I do have one friend who is also in the software business, but his skills lie in other area of production. He admits he cannot program.

For your vision to come true, programming will have to become much more fundamental, to the point that something else will have to be cut. Which other subject should get the axe?

Yeah, that might be it - the thought that I could live another 80 years and we'd still be doing the same old shit with different paint (now with more VR!) on Earth has been somewhat banished. It might be that I'm just too used to the results of the internet and telecom revolution to make it seem futuristic since I grew up with it, and that I haven't seen the big thing that completely separates the world of my adolescence and the world of my adulthood. This seems like it could be that big thing.
Vagrant ist nice for testing but I’m not going to deploy services to VirtualBox (we use kvm for that). Of course there are dependencies outside of the Python ecosystem but their influence proved to be negligible till now. YMMV.

I don't think it's a little known fact that std::map works that way, ie. that operator [] inserts if the key doesn't exist (or at least, it's surely not little known among people using C++?).

Also, I don't think you can have an infinitely expanding std::map in the same way, because all the key/value types have to get rolled into the type signature of the top level map. It's not that hard to write something yourself to achieve it, but it's not going to be the one-liner that it is in Python.

Ahh, so thats why It went down so quick. Hahaha thats hilarious.
> Even if you had blueprints that said "here's exactly how to build a space telescope" just building it and going through all the proper testing would be quite expensive.

As launch costs go down, the cost of experimentation is going to go down, leading to faster turnaround and less on-the-ground testing. Rapid iteration will eventually be the norm.

Like asynchrony, I don't understand this argument at all. You can play however you want in chess. It doesn't change the actual victory condition, nor does it in Go. The sub-objectives during a game of chess appear to me to be equally deep and important as the sub-objectives during a game of Go; namely, they are the whole point. Like in Go, you win by conceding some sub-objectives and pursuing others.

From scanning the source, if a websocket connection is backlogged, messages sent to it are dropped. So I'd imagine it'd handle it fine :)
Also, it's interesting you find it hard to make a critical mistake in Go - this feels very common to me. For example, a decision like deciding to defend a group instead of sacrificing it (which comes up all the time) often snowballs really quickly.

I do that too, but you have a lot of room to back out before your one mistake becomes a losing mistake. If I neglect a group inappropriately, and then make it heavy, and then try desperately to defend it, and eventually fail to survive with no compensation, that's a lot of mistakes; and I usually could have chosen to stop and cut my losses for quite a while before it came fatal.

In chess, you can have long sequences in the midgame and endgame when the game is on a fine tactical balance, and one not-obviously-awful, ill-considered move can either put you in an immediately resignable state or make you spend the rest of the game fighting on the brink of defeat, trying to draw. And that's not really a style of play you can opt out of if your opponent chooses it.
Ah, that most Western of ideas — that to get consistent physical exercise it is necessary to "go in" for a "workout."
Steve Jobs said in the intro of the phone that the apps were "just the internet" or some such. Personally, when I heard that I just ignored the iPhone.
I noticed that a simple, open ended task with a lot of time to solve it gives you a nice idea. I'm not sure what kind of task would be applicable for you, but I do a simple database manipulation in python. Some people will just do the minimum that works (or sometimes doesn't), but some will send the whole git repository, show that they did tdd, generate documentation, handle logging/reporting, etc. It becomes obvious quickly who do you talk to.

These are done at home before the interview - I don't think we need to worry about anyone getting outside help to get a perfect answer. With the amount of bad/mediocre answers the onesI'm looking for tend to really stand out. And issues can be verified at the interview.

The trick is to invite people to go as far as they want instead of giving strict boundaries. And lots of time. If it should take an hour to complete, give out a couple of days before the interview anyway. If the answer is really good, the interviewed person will be able to talk for hours about the details.

The difference between a programmer & a hacker
At some level it was sloppy thinking, yes; most bugs have some obvious-in-retrospect reason they were stupid. You may be right about how to think about this one.

I've seen other defaultdict bugs -- this is just the case with the highest eyeball-count-times-attention product I can point to.
Apps/websites is going to be a cyclic thing. New platforms created as walled gardens are a breeding ground for apps but over time anything that is not the full internet will feel constrictive. And once full access is available there will be alternatives for apps using an open standard.

In the longer term these cycles will become less extreme because we are migrating to a model where every device will always be 'online'. At that point apps will lose a lot of their power.

Another thing that will drive migration to web based applications is that selling a subscription is far more lucrative than selling a piece of software for a fixed amount.

Apps are transitional, and I think they always will be.

They can give a short-lived advantage over the functionality that can be created on new devices, especially if not all the hardware on those devices is supported or accessible by web browsers.

For instance, on the current generation of mobile devices there are all kinds of input devices (gps, compas, inertial guidance devices) that are not supported by HTML but I fully expect future versions of HTML to allow access to those devices.
Oh yes, definitely. I'm just explaining why there hasn't been a privately funded space telescope yet.
Not everything that charges money needs to be close-source.

That's obvious. Programmer is somebody who create source code. Hacker is someone who learn alot about IT stuff and knows multiple times more than typical coder. Someone who can solve real problem. Programming is a craft, hacking is an art.

All magic comes with a price
Personally I would just go for Virtualenv, but you'd be surprised if you know people do with virtualization. I've mostly seen it in Windows shops, but it's by no means limited to that. A common "anti-pattern" I've seen is to build a vmware image, or set of images, that run your "environment". Developers then spin up copies and request changes that they need be made to the "master copy".

When it's time to test and deploy, the code is deployed to a vmware image, which is then sent to the testers. When everything checks out, the code is once again deploy to a new copy of the image, which is then promoted to production.

On argument we've seen is that it makes it easy to do a rollback of the system, using vmware snapshots. It might be a sensible idea in some cases, I just thing it's a bit weird and some overhead.

The worst use case of this I've seen is a Telco, where you needed to spin up as much 12 vms, depending one what you and your teams was working on. But then again that's the same company that read the Perforce guidelines on recommended setup and still decided to just pill all the projects in to one repository.
