Goodbye to my grandfather March 18, 2015, 6:13 am
We saw him on Sunday wheelchairbound on Sunday but the following day his condition worsened by Monday. He was seen by most of my immediate family on Tuesday (his 80th birthday) which he was on life support. I got the news this morning that he passed away, which is saddening and which will likely upset my mother, grandmother, uncle and others.

Happy 32nd International Kaiser Day March 15, 2015, 4:34 pm

I am still here, still breathing and still staying busy. 2014 was definitely the year of 're-adjusting'. With the majority of my worries and problems finally behind me, a new goal to focus on and future contract work with NightDive Studios, I can definitely predict lots of potential this year.

My Tree Skiing Presentation (Video) March 11, 2015, 1:20 pm

My Doom Presentation March 11, 2015, 11:45 am
I'm taking a public speaking course, and one of the assignments was to prepare a speech about a hobby. So naturally I chose to talk about Doom. I presented it this morning and did so pretty successfully. Many of my other classmates were nervous wrecks and were very unprepared. So I sort of over-performed for the expectations of the class. I think I sold the game really well!

First I want to apologize in advance to TimeOfDeath, as I used screenshots of some of his weirder maps as examples of "bad maps" but only because they were very obviously weird just from looking at the pictures. I don't actually feel that way towards his maps. Most screenshots of 1994 maps I found were mostly just bland, had a slime trail here and there, and didn't appear to look far from what you would see in the IWADs. Some of the screenshots I chose for the presentation don't necessarily or accurately represent the points I wanted to make, I just thought that they would be the most visually appealing, obvious, and communicative of the particular point I was making.

Second, a good bit of the information in my presentation was a bit over-simplified. My original presentation was loaded with statistics and technical explanations. Even though I was sure I was clear, my wife said it was way too complicated for a presentation and no one was going to get it. My wife helped me simplify it (against my will) to break it down so that it was much easier to understand. I think it came out much better that way in the end.

Another thing I want to mention is that while some information is mostly pretty accurate, some of it is pretty embellished, and in some cases is downright wrong. I only did this because I was sure no one would call me out on it, and that it helped the presentation seem a bit more interesting.

There are plenty other points I wanted to talk about, such as what a wad file actually is, the differences between IWADs and PWADs, random level generators, source ports, capture the flag, TC's like Aliens, Batman Doom, Ghostbusters Doom, Simpsons Doom, demo recordning and speedrunning, but it was a lot to squeeze in a presentation that was assigned to be 3-4 minutes long.

Anyway here you are. The gif animations only appear correctly through google slides. If you view it in powerpoint, the animations choke up. Not sure why.

Below is the script I made for my presentation. Each greater than symbol (>) represents a point where I'm supposed to click to change slide or move on with the presentation.


Good Morning, Everyone.

My name is Jon, and I have a confession to make.

I am kind of a nerd.

Not like a Big Bang Theory Nerd -- I don't know anything about Star Trek, Star Wars, or Lord of the Rings, or about physics or chemistry.

I've never collected comic books or went to any conventions.

And I've never dressed up like a wizard to play Dungeons and Dragon's in my mom's basement.

But if I'm not here in school, at work, or spending time with my wife and dog,


Then I'm probably at home, playing Doom.

Doom is a popular computer game developed by Id Software in 1993.


It was so popular in fact, that a survey in 1995 found that there were more computers in the United States that had Doom installed on it, than had the Microsoft Windows 95 Operating System.

It was the first game to feature Head to Head Multiplayer that players could play against each other over an internet connection.

It's exciting new gameplay was so addictive that in the year it came out, it was said to be the number one cause of decreased productivity in the workplace in businesses around the world.


I first played Doom when I was three years old. My oldest brother came home with a set of floppy disks and installed the free 9-level shareware version of Doom where I got to play Doom for the very first time -- with all the cheat codes on, of course!

I played it for a while, but I picked it up again around the age of 13, which rekindled by love for the game.

I'm now 24 years old and I have not stopped playing.

So how you play a game for almost two decades and not get bored of it?


Well a major reason has to do with the WAD file system.

WAD Files are a system in which Doom players can safely run modifications with their game.

This was created by the developers of Doom to encourage players to play Doom and make modifications to it so they could play Doom in a way they most enjoyed.

This is different than most games both made at the time and today, that often require you to learn how to hack the software, sometimes corrupting your game in an irreversible way.

This system allows players to cycle through different modifications safely with no consequences.


So, I keep flashing this number on the screen -- One Hundred Fifty-Four Thousand, Seven Hundred Fifty-Eight. What does this number mean?


This is the number WAD files available on the internet today.

Most of these WAD files can contain anywhere between one and thirty six new Doom levels in each individual file.

If you were to play every single one of these Doom levels for just ten minutes -- back to back with no sleep or breaks, just straight playing Doom,

> (same slide -- words fly in)

It would take you 3 Years, 2 Months, 9 days, 18 hours, and 10 minutes to play through every single level just once.

That's a lot of Doom!

Now when I say there are over a hundred fifty thousand new Doom levels to play, that doesn't necessarily imply they are all going to be good.


In fact, it would be pretty ignorant of me not to mention the pretty large handful of levels that are confusing, don't make sense, or are simply not fun to play.


It's also not fair to say that they will all only take ten minutes. Some levels are very puzzle-oriented, complicated, and have waves of tens of thousands of monsters, like the ones shown here. Even with the most powerful guns in the game, it can take as long as 2 hours to complete one of these.


But even with a seemingly endless amount of levels to play, WAD files can change other things about the game too.

For example...


This is a Doom modification that accurately replaces all the guns in Doom to the ones from Call of Duty 4: Modern Warfare.

If you are a Call of Duty fan, and are bored of playing the single player campaign, which I've heard only takes about 45 minutes,

You can play through Doom's levels with this modification and feel right at home.


But the part about Doom that really gets me off the most, is Doom's level design.


With free level editors you can download on the internet, such as Wad Author, Eureka, or Doom Builder, you can draw lines to form enclosed shapes, which become sectors, which are used make up rooms or parts of rooms.

And when assembled together, they make up the floor plan for your doom level.


After that, you get to do the fun part, which is picking the colors and textures of the floors, walls and ceilings.

Then move on to placing the guns, items, and monsters in the level

And setting up traps for the player, and creating secret areas for him to find.


This is the first level of Doom, which was made in 1993.

Now, technology has evolved a lot since then, and as such, Doom's level design has gotten increasingly complex.


This a level made in 2002 by Kim Andre Malde

And if you're a real lunatic, or just have a lot of time on your hands, you might make something like this:


This is a level titled "The Eye" by a guy who goes by the alias "Mouldy" made in 2012.


This is what the level looks like from the inside.


These semi-realistic surreal environments can feature the detail, craftsmanship, and devotion that would rival something like the Sistine Chapel.

This is a level called titled "Vrack 3" by Fredrik Johansson, and you can see the individual sectors that are used to make the inset ceiling lights and hand rails.

The best part is that when you're done with your creation,

You can fill it with rocket launchers and shotguns and monsters and blow everything up by playing Doom inside your masterpiece!

Have you ever had a great uncle with a model trainset? Don't you just want to crash the trains into each other?

That's what this is all about!


These are some other levels created by Doom level designers in the last decade.

This one is called Deus Vult 2 by Huy Pham


This is a work in progress by Ed Cripps


This one is called Sunder, made by a guy who goes by the name "Insane Gazebo"


This is actually a level I made recently -- sorry it's so dark. Darkness looks cool in Doom!


Many people get into Doom level design for different reasons.

This is DWANGO -- one of the earliest and most popular levels ever created.

It was designed specifically without monsters and with tons of weapons and hiding places to be fun specifically for players who want to play against each other in a game mode called Deathmatch.


Other reasons people get into level design -- and this one is my personal preference -- is to make levels with extra monsters and traps to challenge more experienced players.

These types of level designers get a sadistic pleasure from watching the top ranking Doom players in the world suffer in their treacherous gauntlets


And other people like level design for the artistic aspect of it. This level is very difficult too, but it's shown without the monsters.

This level is titled "Swim with the Whales" and features an abstract high-contrast blue theme.


But the reason most people get into Doom Level Design is for the ability to create their own worlds and adventures.

Many modern video games today often have design teams of hundreds of people, with each person working on a very specific segment of the game.

This can be very monotonous and tiring.

Doom is a very fun, fast, and easy way to give players the ability to exercise their creative freedom.

My name is Jon, and Doom is my hobby.

Thank you.


[SOLVED] Why is the output negative? March 10, 2015, 9:59 am
This code is supposed to calculate e to the power x. It works fine at lower numbers, but then at x = 3.6, the output starts to decrease as x goes up. What's wrong?

C language.

EDIT: The problem was that "factorial" function was an int, so at high values, it won't work.

#include <stdio.h>

double factorial (int n) {

double f_result = 1; //factorial result
int i;

for (i = 1; i <= n; i++)
f_result *= i;

return f_result;


double power (double base, int exponent) {

double p_result = 1; //power result
int i;

for (i = 1; i <= exponent; i++)
p_result *= base;

return p_result;

double compute_ex (double x) {

double division = 1;
double div_sum = 0;
int counter = 0;

while (division >= 0.0001) {

division = power (x, counter) / factorial (counter);
div_sum += division;



return div_sum; //div_sum is the sum of the infinite series, which is e to the power x


int main()

double x;

printf ("Enter the value of x:\n");
scanf ("%lf", &x);

printf ("e to the power %.1lf = %.2lf", x, compute_ex (x));

return 0;


When random theme songs get stuck in your head. March 6, 2015, 4:38 am
Ever had those times a song regardless of how long its been since you last heard it somehow manages to pop up in your head without even trying to think of it, and keeps playing over and over?

Just recently the Inspector Gadget theme song keep playing repeatably in my head even though I haven't even seen the show in over two decades.

Is there any particular reason why this sort of thing sometimes occurs with peoples minds?

Coins fall out of my pants in the car. Why? March 5, 2015, 7:53 pm
I'd like to interrupt the steady stream of news articles being linked in the Everything Else board to ask for some assistance with a conundrum that has been affecting me for a considerable amount of time now. Sometimes I carry loose change around in my pocket, but whenever I exit my car there it is sitting on either the floor or the seat. And that's a best case scenario. Sometimes I may want to buy something from a vending machine or make a call from a payphone because my cell phone is dead, but lo and behold, my change is gone. I can't for the life of me figure out why this is happening, but I have a few hypotheses:
-Money just doesn't like me
-I'm being pickpocketed by bums without realizing it
-God himself is removing the change from my pocket
-The government and/or college is removing the change from my pocket
-Coins are just spontaneously melding with the pants
-I collected 100 coins and they disappeared in exchange for an extra life
-At some point I keep getting repeatedly mugged by pirates and forgetting it

If anyone can offer me any assistance, please do. This is one of the few issues in my life right now that I can potentially do something about as soon as I find out what it is. I will personally mail you 2 quarters if you can give me a solution that works.

Phone Scams! D: March 5, 2015, 2:39 pm
my landline is apparently a magnet for phone calls since the past month. lately, I've been getting a lot of calls on my home phone. usually, I end up with no message on the phone, most likely due to some dummy getting the wrong number. this is fine, mistakes happen. but what I've also been frequently getting is something even more interesting, and rather catastrophic to think about had I answered the phone that time. that's right, I'm talking about phone scams, the ones where someone is demanding money over the phone from my paycheck, or something among those lines. and I seem to get them once or twice a week that it's getting ridiculous.

the most recent one happened just yesterday. around the morning time where I live, I got a message, apparently from New York of all places. so I played the message and I was quite shocked at what I was hearing. someone had called my number, claiming to be from the IRS and saying some shit about having a lawsuit filed against me and an arrest warrant. I figured it was a scam since I really don't do anything wrong (plus I had already payed for my taxes last weekend). I had a gut feeling that the IRS doesn't directly call random peoples' phone numbers. I decided to Google this particular scam, and I found out that it seems to be targeting others in the states as well. so I showed this to my father and he called the police about the message we got. my dad knows when something's a scam anyways, since all these people want to do is take money out of our pockets.

I fucking wonder how these crooks could come up with this sort of sophisticated scheme of masquerading as IRS agents and I hope I'm not the only one who is ending up receiving these messages. I also am wondering if I should disconnect my landline, given how I am so tired of people constantly calling my home phone number.
