38leinad··on Finding a Creature in Ethereum's Dark Forest
Sorry for maybe asking a stupid question, but if i understand correctly, the nounce is just a secret as the private key. But the nounce is not needed for the signature check? So, it can be choosen random and then simply forgotten after signature generation? After first quick google search, it looks like there is also the term nounce use here but it is deterministic and just counted up which does not seem to fit with the article: https://developpaper.com/the-nonce-of-ethereum/ Am I missing something?
38leinad··on John Carmack Quakecon 2013 Keynote Livestream
if you are interested in rendering, don't miss out John's talk at 5pm dallas time today: "Principles of Lightining and Rendering with John Carmack" http://www.quakecon.org/event-schedule/ Should also be streamed on the quakecon twitch stream. according to the keynet video, it is supposed to be a talk he has given internally at id before and was urged to redo it at quakecon.

"John will present a lecture-style presentation on the physics of light transport and rendering. He will discuss how light behaves in the real world, and the approximations and compromises that are involved in simulating the behavior with computers. Note: not for the technically faint at heart."

have you tried paint.net? i really like it for doing pixel art.
38leinad··on What's Wrong with the iOS 7 Icons?
someone saw the "ios in the car" icon? http://cdn.iflowreader.com/wp-content/uploads/2013/06/apples... To me, this is the most ugly icon I have ever seen. ever!
38leinad··on Take music to a new dimension
anybody can describe what makes this better then spotify?
38leinad··on Apple Unveils iTunes Radio
maybe a new ipod touch? does not have a speaker but only a camera at the usual location.
38leinad··on Pixar's Chris Horne Sheds New Light on Monsters University
Anybody knows how other companies like universal's animation department (ice age, despicable me, ...) stand technology-wise? From the visuals, i always assumed pixar is setting the standards but now knowing that they just start to use unified raytracing, the gap might not be that big...
38leinad··on An Introduction to Java Web Services Programming
i am not anti-java. not at all. but to be honest, creating this simple web service shows really how complicated some things are in java.
38leinad··on OpenGL 101: Textures
I also found that its definitely the best guide. A good companion to look at some things from another angle are also these tutorials: http://duriansoftware.com/joe/An-intro-to-modern-OpenGL.-Tab...
38leinad··on Try Objective-C
sometimes I really get annoyed over here because of stupid comments like yours. keep it to yourself!
38leinad··on JS Objects: Inherited a Mess
thanks for the clarification. that helped a lot to get the understanding straight. always thought I am missing something fundamentally. Looking forward to the read.

in the end i also think super-calls are not a very good concept as you normally don't know what the super calls are doing internally, but somehow it seems like the way to go as almost every mainstream language/framework is supporting/doing it... but i guess that's the general bitter taste i get from classical inheritance...

38leinad··on JS Objects: Inherited a Mess
I never find an answer to my most daunting question: how is the pattern for doing something like a super call in this prototypal model? bar.prototype.methodname? what if the method is only defined in the proto-prototype? I.e. Foo? Do I then have to explictly know this and write bar.prototype.prototype.methodname?

I hope you know what I mean. This concept of super-calls does not transfer well to prototypal inheritance for me. Are there other patterns that should be used instead?

38leinad··on Quake 3 engine in Rust
not 100% on topic, but as the author is doing his mod because he likes to have a voxelized and fully destrutable word: I remember Red Faction. Is there any in-depth review/interview on the technology they used at the time? Looked like "simply" carving out destructed structures from a polygon model; But would be interested in the details...
38leinad··on Introducing HTML’s new template element
can someone eleborate in which way this is different to what you can do today with a script-tag? E.g. http://knockoutjs.com/documentation/template-binding.html

Am I missing something?

38leinad··on Don't Copy-Paste from Website to Terminal
i think gizmo686 is aware of that. what he says is that he trusted the source where he c&p's from. if you don't trurst the source you should not blindly copy any command. Even one flag/parameter that you might not know can do harm. There do not have to be hidden characters to make it harmful and dangerous.
38leinad··on GDC 2013: Michael Abrash on “Why VR is Hard (and where it might be going)”
Great! Was already considering buying GDC Vault annual fee of 500$ to just see this presentation... let's see if the read can spare me this money. :-)
38leinad··on Two Letters from Steve Jobs
I personally think writing just "OK" does not make him less of a jerk. Seriously! This guys friend is terminally ill and he does not have a few nice words to spare? Just "OK"???
38leinad··on List of worthwhile DOS games
oh my god! haven't played games in some time but i was just reminded to boot up transporter tycoon when time permits...
38leinad··on Germans and Jaywalking: An American's Perspective on the Berlin Tech Scene
hm. was in columbus, ohio a few weeks back: if you are at certain places in the US (an like walking) you have no other possibility then jaywalking. cities and especially indudstrial/commerical areas are not constructed in a way to make it easy for pedestriants. you can be happy if there is a pedestrian crossing within the next mile...
38leinad··on Sublime Text 2 Web Inspector
Note that this is more then reloading the web-page. It actually seems to be doing hot code-replacement on the fly. I only know this from Java in the debug mode or JRebel. Having this work for Javascript will be really neat... I am feeling more and more confident that my move away from Webstorm to ST2 was the right one...
38leinad··on Show HN: 6 months ago I quit my job to pursue indie dev. Here is our first game
Looks great! Did not play much yet but I guess it needed a lot of trial/error and deep insights to designer some of the hard "levels".
38leinad··on What Does 200 Calories Look Like?
I have always asked myself why that is so? how did it happen that this "mistake" got into everyones mind? you don't say "meters" if you mean "kilometers"...
38leinad··on So you think you can tell Arial from Helvetica?
actually a was bored after ten right answers or so. It was really easy. At first I only looked for what "looked better" because I generally like Helvetica but find Arial really ugly. After doing the first answers, I started to see the minor differences and now understand why I like Helvetica better.
38leinad··on Math for Game Programmers 04 – Operations on vectors
he also seems to have a nice article on 2d platformers: http://higherorderfun.com/blog/2012/05/20/the-guide-to-imple... marked for reading.
38leinad··on Quake Video Game Industry Legend Paul Steed Has Passed Away
read the sequel; then, you should be looking forward to it...
38leinad··on Raspberry Pi book by The Pragmatic Programmers
please note that i did not look at the book; so it might be actually worth it's money; but i am a bit biased and the first thing i think once a new pragmatic programmers book hits the market is:

somebody tries to make a quick buck. whatever is in this book, is basically just a quick write-up of what can be found in the internet for free anyway...

38leinad··on The Differences Between Germany and the United States
seinfeld is a really good example for this. a hilarious show; someone watching the dubbed german version would never understand what's funny about it...
38leinad··on Lessons learned from MITx’s prototype course
why does that make the course look bad?
38leinad··on The Purity of Running
Same for me. It is not so much a denotational state but a highly focused experience to process and reflect on what has happened that day (or the day before... I am not so much an earlybird...).
