On virtual reality

Many people view virtual reality (VR) – and let’s point out the big elephant in the room, HTC Vive – as “the future that is now.” Then they hype hype hype and buy it. Then they complain that there aren’t enough VR games, that they’re all bad, etc.

But instead, consumers need to look at it from this standpoint: Where were video games at ten years ago? Twenty? Ten years ago we were doing these low-poly games and the best console on the market was PlayStation 2. Increasingly developers understood the architecture more and more and were able to hyperoptimize their games to exploit what the hardware could really do, which still can’t be emulated at full speed today without hacks along the way. Now it’s 2016 and we are seeing Direct3D 12 and photorealistic graphics. No, not FSX “photorealistic,” but as in faces rendered realtime and so humanlike that you couldn’t even tell whether they were fake or real. And in the 90s and 80s, we didn’t even have 3D graphics good enough for gaming, with the exception of some rising consoles such as the N64. And even they were extremely limited in capability.

Thus, I implore consumers not to look at problems in the “now” but in the future. In twenty years we were able to achieve photorealism for realtime applications such as gaming. And now that the whole issue of graphics has been resolved (since any graphics card made since last year is able to render basically anything you wanted on it), we have new issues related to VR, such as wield variably shaped items, move around in a physically confined area (less than 9 m2!), sense their environment beyond sight, interact with the virtual environment? Currently these problems have yet to be solved. But if we literally invented (and perfected) 3D graphics in 30 years – could we not invent and perfect virtual reality in the same amount of time?

And the whole idea of how these problems will be answered frightens me because the solutions might become intrusive. What if in 2030 we simply became accustomed to human alteration? What if 2040 the first human beings entered the long-awaited “dream pods” that would cede their consciousness to the hands of a computer? What if in 2055 we decided to just transfer our entire beings into solid-state drives? What if in 2085 the human race just disappeared from the face of the planet? Soon, virtual reality will become the only reality. And it’s turtles all the way down.

So don’t complain because one day, you’ll miss playing on a monitor.

The AoS bot that I originally wanted to make

crossposted from the BnS forums:

A few years back I thought of exactly this, a decent bot. At that time I did not have the experience to actually create AI but I started slowly working on a client implementation in JavaScript anyway. My imagination ran aloose: if I could make excellent AI, I could start a clan of “noobs”, watch everybody get rekt in League, and then reveal how I did it. Built-in inaccuracies and limitations would prevent any detection of ESP, because the AI would hypothetically only be able to view the map and within its line of sight, perform some limited communication, and have a reasonable (and adjustable) hit/miss percentage. The bot could also build prefabs, and other bots could join in or defend as they are building.

I thought about a design for such a system of bots for a very long time, and I looked at some dumb bots some people around here made in Python. But I wanted the “unauthorized” approach, so I was not inclined to create a serverside script. I wanted a clientside approach that would be controlled by the bot master’s computer, so that I could simply and inconspicuously deploy three or four well balanced bots on a server. The problem, of course, is that there is a limit for clients per IP address.

The problem in the holistic sense when I envisioned this concept was not the algorithmic portion as it was the implementation and the time that it would take to complete this undertaking, which I repeatedly underestimated. Moreover, I was not familiar with three-dimensional A* or machine learning concepts. I was eager to learn them, which is really what matters. But time always turned out to be the greatest deciding factor in all of this. My time was always fragmented; 15 minutes doing this, 15 minutes doing that, rather than a solid slot of 3 hours of project time. And due to school, my free time varies from 3 nice hours of relaxation to absolutely nothing.

Many of you think that this is my excuse all the time for not being able to do anything. But it’s true, and so my disposition to commit to things has fallen. That’s why I never carried out the whole bot thing in the first place. I just did the backend and that was it. You want to pressure me into doing it for that AoS of the Future project, fine. You want to pressure me into doing it so I can fill your servers with future-proofness, fine. You want me to do it for the betterment of all your little FPS projects, fine.

Suffice to say, a well scripted bot would be perfect in imperfection. But I am not one to do it.

On computer terminology

I see in many books certain attempts to ease the apparent pains of using computer terminology.

For example:

With the help of Tim Berners-Lee, the Internet became popularized with the creation of the World Wide Web.

This simple statement becomes this convoluted paragraph:

With the assistance of Tim Berners-Lee, a computer technology was developed that allowed computers to communicate each other through what became known as the World Wide Web, which people could connect to through new software such as America Online and CompuServe that came in floppy diskettes. Thus came the existence of the Internet.

Authors continue to be extremely cautious in introducing computer terminology in their writings. But the truth is, who doesn’t know what the Internet is these days? Who doesn’t know what software is? And when authors do use the terminology, they often surround it with these metaphors so as to try to compare it to tasks once done by hand. “The Internet, like a pair of telephone wires, …” “With the advent of the microprocessor, computers once the size of rooms became smaller than the ‘a’ in this book…” This is the virtual world we’re talking about here. There is no substitute for these things.

No. Heck, no. If you’re going to include words like “axle” and “spigot” in a book and don’t bother defining them, then don’t bother with “die size” or “parallelization” either. Suck it up and make people learn the jargon. Don’t talk to them as if they were elderly people.

On Anki: 14 months on

Since January 27, 2015, the first set of cards that I had inputted on Anki, I have learned 550 kanji. No, not just stared at for 5 minutes… LEARNED!

When I first heard about spaced repetition, I thought the forum posts were too good to be true. But they prescribed the same advice: Anki. Anki. Anki. Study every day. Mine the crap out of Japanese and fling it into Anki. And I haven’t had any complaints about the system ever since that day, not because I’m an optimist who only looks at the positive side of “good” things, but rather because it’s (1) a scientifically proven model that accurately works with, not against, the dynamics of the brain, and (2) because once you set it up, you can study from wherever the heck you want. I study on my phone because it’s the most convenient, but I have to input new notes on the computer because it would take an eternity and a half doing it on a tiny phone with an even tinier keyboard.
