Others mention that it will be visible to other users, but I can be more clear in what that means: At first glance, it seems you could use a negative-balance user to hide fractional reserve. Say the sum of all deposits is 2000. You only hav

First off, great idea! The screenshots look friendly and I think it would be something I'd have used when I was a kid. That said, you have some stability/UX issues. The loading delays are very long. I can easily see kids losing in

I would agree, but if you don't update WhatsApp it disables itself after a week or so.

Not too long ago, the internet measured top speeds in tens of kBps. So first off, give it time. Engineers are good at solving problems like this. Furthermore, mesh networking is a fundamentally different architecture solving a different pro

Hahah yes!!!! Thank you SO much. My only regret is that I have but 1 upvote to give.

Wow! That was pretty fun. I just wish it had a description of which buttons were which; I died after only a few minutes because I couldn't figure out which button was L.

Good point! Still, I think the best hash inversion I've seen is slightly under 1/2 the hash space (2/5ths?). Using a 512-bit hash like SHA3, even at an ungodly hash rate (1 TH/s), you still get approximately 2^141 seco

The issue is that you can parallelize the "unlocking" operation. So, if one person is attempting to unlock, they solve in 10 years. If two people attempt, it's solved in 5 years. If the NSA puts all their computers on it,

I like the parallelized hash chain construction idea; I've never seen that before. One could improve a chunk of the chain by having checkpoints along the way. As the author mentioned, it would suck to be 2 years into mining a 35-year

I love how whoever mods this site now doesn't even have to follow their own rule about not editorializing headlines. Mods: Don't be hypocrites. If you're going to enforce your "only use the source title" trash on

You assume the 5% per annum is going entirely to equity. Consider that property taxes, HOA fees, utilities, mortgage interest and maintenance all contribute to the ~8% figure, and your p/a equity looks closer to 3%. Now let's com

You make a pretty big assumption here: that anything you can invest in to earn money passively CAN be guaranteed. What you mean by "generate guaranteed income" is "to allow me to grow my investment". After all, invest

Ding ding ding. You are correct! The number of people showing up here (disproportionately from California, actually) is pushing housing prices through the roof. Houses sell about 10% over ask pretty much anywhere. Rent has doubled for mo

"Work" is pretty broad. Let's define it as "have a productive experience" because any non-period matched programs have issues other than pure compatibility. For example, bring many old DOS programs up on modern ha

If you really believe that, I'd suggest you check out the WCS Season 2 Grand Finals from last night. Really, all of the WCS event. Proxies do quite well against standard build orders--that's one of the things that makes pro play

Exactly! I agree. However, all the current system does is penalize people who follow the submission rules (since their content doesn't get up-voted), and generate annoying comments about the "original topic" for the rest of

Mods invisibly changing titles really bothers me. It's even worse that the mods decided it was a great idea to silence debate by [dead]ing the topic when HNers discussed possible alternatives. Makes me wonder how much longer I want to

I'm not sure if there's a cause-effect relationship here. MakerBot was only founded in 2009 [1], RepRap released their first project in 2007 [2] and the project I was a part of, Fab@Home, open-sourced in 2006 [3]. I can't sp

The early GPU Gems books might be of interest to you. They are full of stuff like frame timing subtleties and interesting ways to solve common game loop problems. These days, you can probably get them for less than $50 each, too.

Hi! Wow, very nice to meet the author. Most of this was written after I'd already finished my game, but the Object Pool article was part of the inspiration for my memory pool class [1]. Thanks for everything you've written, it

I wouldn't hold your breath. When I last used this site in 2010 [1] it wasn't that much less complete. Still, what is has is very useful and I'd suggest giving it a read. [1] http://web.archive.org/web/2

While I agree with most of these as great reasons for moving to Austin, as a resident I'd caution those interested in moving here to not take them at face value. Come visit and consider what they're not telling you when making a decision:

That's not a particularly good analogy, because both roles require significant commitment to practice and study. Trying to achieve both would take would likely render you worse than most at either. Being a good programmer takes training a

Viktor Zykov (one of Hod's grad students) did something like this in 2006 [1][2]. He built a "starfish" then had it learn its own shape through experimentation, then evolve a way to move. [1] Video: http://www.youtube.com/watch?v=msw267li

My first thought was "this is really familiar"... then I realized it's because I used to work in Hod's lab :) I think it's interesting that most of the robots that evolved don't have rigid components. I wonder if reducing the structural su
