javanix··on Ask HN: Which DRM-free ebook reader to buy?
I had a Nook Glowlight for about 6 months and the main downside is that the light screen is incredibly fragile. I am careful with my gadgets and I've managed to break 3 of them just by accidentally knocking stuff onto them (like, slipping and fumbling the Nook onto my keys, etc). Granted, Barnes and Noble replaced all of them for free (even out of warranty) but it was enough that I went and bought a Kindle Paperwhite and (minus the software) it is a generally superior device. Additionally, the Kindlegen software combined with stripping the DRM off of my Nook purchases allows me to read perfect epub-to-mobi conversions of all of my books on the Kindle without too much trouble.
javanix··on Ask HN: Please critique my (revised) cover letter
Cool - thanks. I'm flattered that such an esteemed member of HN took the time to give me some advice.
javanix··on Ask HN: Please critique my cover letter and settle a debate
Thanks for all of the help, everyone - HN is great for this sort of "real-world" feedback.

I'll update this thread later when I have a chance to make some changes.

javanix··on SpaceX wins $440M contract with NASA to develop Space Shuttle successor
According to http://www.nasa.gov/centers/kennedy/about/information/shuttl... each Shuttle launch cost about $450 million.

This contract amount seems to suggest that SpaceX launches will come in significantly lower than the Shuttle - a very good sign for continued space research.

javanix··on Gow - The lightweight alternative to Cygwin
Does this allow you to run GCC or anything compilers on Windows?

I thought that was the main draw of Cygwin.

javanix··on SLR Camera Simulator
Many cameras (including mine) do not have an LCD that accurately reflects shutter speed or ISO settings.
javanix··on Ubuntu Releases 12.04 LTS Precise Pangolin
If you use two different cards and some playing around with X.org you can get the nVidia drivers to play nice with 3 monitors.

Granted, it might be the most difficult configuration I've ever tried to figure out on *nix and I'm not trying to shoot you down, but for anyone reading your comment it's not actually "impossible".

javanix··on Apple Isn’t The Only Disruptor: How Amazon Is Killing Publishers
I don't understand this at all.

I don't read books for the experience of turning pages - I read them for the experience of reading and interpreting and taking in a story.

What exactly is more romantic or useful about reading the latest Stephen King novel on a tablet versus a bound sheaf of paper?

The death of the printed book boils down reading to the bare essence of appreciating the written word.

javanix··on Kids build great things.
Or, you know, ask the same thing to a bunch of traditionally-educated children and you'll get the same answer: a black dot.

Montessori kids have been rewarded over the years for giving out-of-the-box answers and that's probably what their mind jumps to first. Their ignorance isn't what gives them the creative answers - the years of being taught to look for something different is.

If you want to start getting better answers out of your employees/coworkers/own mind figure out how to reward them for random ideas instead of pounding them down.

javanix··on What was the most Badass JavaScript demo of 2011?
The native JS h264 decoder was pretty awesome.

javanix··on Picking a random element from a stream
Here's a link to the Stack Overflow question I found this from.

Pretty cool algorithm!

javanix··on How Super Mario Bros. 3 was made
Here's a cached version from Google. Seems some of the pictures didn't make it through though :(

javanix··on I'm starting to think LEGO is evil
Look: I will fully admit that these sets are really, really cool. My son is getting a gigantic Millenium Falcon set from Santa this year (DON’T TELL) and both my wife and I are excited to play with it too.

But it’s a model kit. We will put it together once and we will play with it a lot and that will be that. It won’t get remixed, won’t get hacked. Eventually it’ll come apart and be put away and not rebuilt because 1000 pieces is a pain in the ass.

This doesn't make any sense to me. Why on earth wouldn't you mix those pieces in with the rest of the pieces you already have from sets you've already disassembled? Sure, the marketing is a little much these days but unless I am sadly mistaken all the pieces still fit together like they did 30 years ago.

javanix··on Show HN: Entire concerts algorithmically "reconstructed" from YouTube videos
It would probably be technically "possible" but I doubt that you'd end up with anything that sounds listenable.

The only bootleg audio that usually sounds decent are soundboard recordings, and when you find audience tapes spliced in with them the difference is immediately noticable.

javanix··on Kindle Fire could be hotter than iPad this holiday season, study finds
If it has the right software and is easy enough to use, I can see this happening. Given the choice between a $400 iPad and a $200 Kindle Fire I think I can see a lot of people taking the cheaper option.

Whether it is sustainable will depend on the performance/usability of the Kindle. The problem with current iPad competitors is that at best, they come in at the same price point as the iPad and fall far short in terms of usability.

javanix··on Show HN: validate.js - lightweight JavaScript form validation library
There isn't really any way to dovetail client-side validation with server-side validation.

Client-side validation should always be assumed to be disabled completely - view it as merely a convenience for your users. Help them switch dates into a correct format, make sure their userids aren't taken before they finish filling out their forms, that sort of thing.

javanix··on Show HN: BestSFBooks, Mashup of the Best SF/Fantasy Books
This is awesome - I've been searching for somewhere to find good new SF/Fantasy for a while that doesn't just entail blindly searching Amazon.
javanix··on Computer-controlled socialist economy gets destroyed on 9/11... 1973
If anything it's a minor coincidence that the World Trade Center was destroyed precisely 28 years after a Chilean revolt.

The two events have absolutely nothing in common with one another other than sharing an arbitrary day and month of the year.

javanix··on Computer-controlled socialist economy gets destroyed on 9/11... 1973
Why was it necessary to put 9/11 in the title of this? I think knowing that the economy was computer-controlled was enough to get me to read it - I don't think the sensational title was really called for.
javanix··on Petition: Direct the Patent Office to Cease Issuing Software Patents
Better to spend your time petitioning for campaign finance and term limits - our only hope is getting enough people in office who are smart enough to do the right technical thing and who aren't reliant on the industries they are responsible for regulating.
javanix··on Petition: Direct the Patent Office to Cease Issuing Software Patents
The issue with this sort of thing is Joe Public is never going to understand the underlying issue with software patents.

Without some politician complaining loudly and simply about the wrongness of an issue, nothing is going to change. Unfortunately the major technical issues of our time (this and net neutrality, for instance) do not have loud, simple explanations.

javanix··on Guys buy island on Craigslist, use Kickstarter to turn it into artist community
Am I the only person who can't find any hard information about the project on their website?

Everything seems to talk about the principles of the project - I can't even find a decent picture of the settlement's current state.

javanix··on Google Correlate by Drawing
Ok, that is way too addicting to visit during work hours.

I drew a standard bell-curve peaking in 2007 and then trailing off to zero into 2011 and everything was either Myspace searches or Washington Mutual credit searches.

Pretty nifty.

javanix··on Mark Cuban: What Business is Wall Street in?
You missed the part where creating that valuation metric is becoming harder and harder due to an increasingly chaotic and fast-moving market.
javanix··on Computable Document Format
I'm not sure I'm entirely thrilled about a new document format that requires a 106mb download to view.
javanix··on Harvard and class
I don't think he was really complaining about the Harvard bubble - just commenting on it.
javanix··on PuTTY 0.61 released
Whoa! It does finally pay attention to my resize bindings, even in Vista. Awesome!
javanix··on Building a pure CSS 3D City
A lot of these CSS posts reference the performance gains realized from using CSS transforms as opposed to canvas because the transforms are hardware-accelerated.

How long will it be before canvas gets hardware-accelerated? Is there a technical hurdle that needs to be overcome in getting (for example) V8 to talk directly to GPUs?

javanix··on Thanks HN UpOut v1 | 9 Cities
Wow, this is an awesome looking site - wish I lived in one of those cities.

I am running on a resource-constrained computer right now - my only complaint is the JavaScript seems a bit slow - scrolling on the main page is choppy. Might be worth profiling on lower-end machines a bit to smooth some of that out.

javanix··on A cron pitfall that will probably snare you at least once in your career
It is kind of amazing how much this explains.

I thought I was doing well when I finally learned to remember the "no cron files that don't include an empty newline" rule.
