How much is my Disney reel worth?
I'm guessing not very much. Original prints of Steamboat Willie would be 35mm and old nitrate film. Most likely this is a relatively modern copy, from the 50s or 60s. Is it a sound film? The original Steamboat Willie was silent, sound was added later for a re-release. Mickey's Misfortune I never hear of that either. The Hindenburg Newsreel is everywhere. I guess an original copy might be worth some money, but again, it would probably be nitrate film. Cut a little piece off the end and see if it burns!
Could ya give me a list of songs?

If Ugly Stiks are such great rods and popular with everyone, why is it...?
Well, "great" has many different connotations and means different things for different people. If you are a weekend plunker and want a rod that is going to last forever and not break even when your grandkids step on it while getting into the boat, then the Ugly Stik is probably the greatest rod of all time. I've never, ever replaced an Ugly Stik rod, and one of my kids is so hard on gear he once trashed a brand new pair of hiking boots in ONE scoutcamp. But no one is going to say that an Ugly Stik has the best casting characteristics, or that it is super-sensitive, or that the company even offers a product line for epic game fish like Marlin. Those big-game anglers have custom-made rods, purpose-built rods, and I'm sure that their equipment is great for that application. Even among freshwater sport anglers, I don't see many of them using Ugly Sticks. The hard-core guys won't touch them -- they don't have the senstitivy or finesse that a better rod has. Ugly Stiks are for kids and fairweather anglers who don't want to spend much and would ruin the more-spendy equipment anyway. So yeah, the Ugly Stick is "great," but it's not "GREAT." You're comparing apples caught from the deep sea to oranges caught in a little fishpond.
If there is a three-digit lock and the digits are from 0 to 9, and a person tries to open it, after how many attempts will he be able to open it?
If there is a three-digit lock and the digits are from 0 to 9, if a person tries to open it, after how many attempts will he be able to open it?This makes 1000 possible combinations, since each of the 3 digits has 10 unique settings.If say a billion people were to open the lock, trying combination after combination until they found the one which worked, and since all combinations are presumably equally likely, we should expect that on average, it would take about 500 attempts.(Since the average number is [math]\;\tfrac{1000\cdot\left(1000+1\right)}{2}/1000=500[/math].)But for any single attempt, it's impossible to say how many tries it would take for success. It could be anywhere between 1 and 1000. It's literally no different than generating a random number from 1 to 1000.
How were programs loaded onto memory before operating systems existed? How was the first operating system installed onto memory?
For my first assembly language course (many moons ago), I was assigned to write a program for a PDP-8 computer that would link two teletype machines so that whenever a key was pressed on one machine, the character was printed on the other. (Sort of a stone-age chat program.)The PDP-8 had no operating system and the way I loaded the program was to enter the instructions in machine code, one instruction at a time, through a set of switches on the front panel of the machine. I’d set the switches (one switch per bit) for the next instruction code and then depress a special “enter” switch that would load that instruction into the next memory location. There was also a “run” switch that I could hit to begin execution of the program once all the instructions were loaded. As I recall, there was also a switch to halt execution, one to execute just the next instruction, and a few other control switches.If it isn’t obvious, all program development took place with pencil and paper. Needless to say, the entire program development and debugging process was painfully tedious. The hardest part about debugging was trying to examine the I/O ports when things went wrong, to see what data was being sent and received by the teletype machines. (I’d toggle in the port address, press a “read” switch and the machine would display the port value by lighting up a series of lights on the front panel—one light per bit.) A quirk of the PDP-8 hardware was that reading the port value, even through the front panel, cleared whatever data might have been there. This meant that every time I looked at the port value, trying to figure out why things weren’t working, I destroyed the state of my program. If the port value didn’t tell me enough to correct the bug, I then had to completely restart the program and re-enter all the input just to get it back into same state, from which I could then advance to the next instruction.This experience greatly enhanced my appreciation of compilers and operating systems when I finally took courses in those areas.
