There is no such thing as a "semi-automatic machine gun." Semi-automatic is mutually exclusive to machine gun.
Firing types....
Full-Automatic
Fires multiple rounds for as long as the trigger is held.
Legal to own in the US after a background check and purchase of a special permit.
Machine gun
See Full-Automatic
Semi-Automatic
Fires a single round when the trigger is pulled.
Automatically loades the next round in the chamber.
Will fire only a single round if trigger is pulled and held.
Most hunting rifles are semi-automatic.
All of the weapons banned under the "assault weapon ban" are semi-automatic weapons with 'scary looking' features (flash suppresors, bayonet mounts, pistol grips).
Bolt-action
Fires round in chamber when trigger is pulled, user must preform manual action to load next round. Also called Lever action, Pump, etc
There is also something called selective fire (if I remember correctly) that limits the number of rounds fired in a full-auto capable weapon. Since full auto fire is very very difficult to aim accuratly, the weapon can be set to fire bursts of one, three, or "until I let off or run the clip dry" modes.
I think the point Mr. Sowell was trying to make with the camera analogy was that for 90% of the pictures I take, the "automatic" defaults produce a good serviceable photo. The advanced features (Program and Manual modes) are available and easily accessable when conditions or desire call for them.
I think Mr. Sowell would compare various programs that he complains about to the camera I learned to shoot on - my father's old Nikkromat. Manual everything, with a SLR light meter. Every shot required evaluating the shutter speed, film speed, f-stop, focus, depth of field, flash/no flash, etc. This was not a camera I could hand to a novice and tell them to "just shoot".
Developers and designers have to make reasonable decisions about default settings, and make those settings easy to change.
They also need to resist the urge to add every feature into the product. Does a chess or scrabble game really need to play music?
There's the Q-codes that have already been mentioned, and prosigns, but for real message word count reduction look no farther than the ARRL numbered radiogram messages.
Were I on vacation in Florida when a hurrican hit, I could send the message back home that "We are all safe, don't worry. There was only slight damage were we are, and we will be coming home soon." as: ARL ONE ARL FOUR ARL TWO
There is some header information needed by the message passing system (NTS), but the base message goes from 21 words to 6.
I was always taught to trade some shutter speed for a higher F-stop, giving a deeper depth of field.
Set the focus so the depth of field covers the likely distances you will encounter your shot.
My son could not stand waiting for two years to see the end of the tale after seeing the Two Towers that he started reading the books.
Even though we have the DVDs.
Maybe my answering his numerous pleas to tell him what happens next with "You'll have to read the book." and sticking to it after The Fellowship of the Ring had something to do with that.
When we got the DVD of TT, he proudly pointed out all the spots where the movie deviated from the book.
I may have to bring duct tape with me to the Return of the King to keep him quiet.
Saw a bit on something like this on PBS a few years back (8-10 years).
They profiled a rural volunteer fire department that was useing a hot air ballon inflation fan. They would place it in an exterior doorway and pump outside air into the structure.
This allowed the firefighers to wear lighter turnout gear, move faster, and see the fire easier (no smoke filled rooms).
The Apollo spacecraft (both the Command Module (CM) and the LEM) were designed to use pure Oxygen but at ~5 psi. This is the same partial pressure of O2 that we breath at sea-level (at ~15 psi, 20% O2), but reduces the need for a beefy structure by using a lower pressure. It also eliminates the need to carry a 'filler' gas like Nitrogen or Helium.
Apollo 1, being a ground level test run was using needed to be run at sea-level pressure, otherwise the CM would have been crushed. Unfortunatly they chose to use pure O2 at ~15 psi to do this test - materials that are flame resistant at 20% partial pressure of O2 are not necessarily flame resistant at 100% partial pressure O2.
In the reviews after the fire in Apollo 1, all of the material within the CM and the LEM were evaluated for their inflammability and replaced with non-infalammable materials. Also subsequent ground tests were run with ordinary air instead of pure O2.
The Shuttle uses air at ~15 psi -- one downside to this is that any astronauts going outside (EVA) need to breath pure O2 for a while to remove their nitrogen load before going outside. If they did not pre-breath the oxygen, they would get the bends (Decompression Illness) from the nitrogen bubbling in their blood.
About a $50 to $100 investment in (new) equipment, less if you are a good scrounger or have a well stocked kitchen.
2 gallon pot to boil proto-beer (wort) in
5-6 gallon plastic tub to ferment in
food grade liner for tub
lid with hole for airlock
airlock *
thermometer (optional)
hydrometer (optional)
funnel
bottles that are sealable
$15 to $30 per 5 gallon batch of beer after that for:
Malt extract
hops
yeast
water
Boil the water, malt extract, and hops - cool (add more water to bring to 5 gallons) add yeast. Wait ~2 weeks, bottle, wait ~10 days (very very important to wait at least 10 days.) enjoy.
Making beer this way you are paying someone else to do four inital steps:
Growing and harvesting the hops
Growing and harvesting the barley
Malting the barley
Mashing the malted barley
Beer is not all that hard - It is theorized that it was originally done by accident...
1991 Gulf War gave us (the citizenry) GPS? I don't think so - there were numerous stories during GW1 about soldiers bringing commercial GPS units from home because the milspec GPS receivers were in short supply.

Cups are not just for male combatants...
18 wheelers - the word you were looking for is little specialized infrastructure.
Interstates, truck stops, etc...
Most of the US is fairly temperate?!?!
Even Atlanta, Georgia, gets below freezing every winter. And don't even ask about Chicago or Minneapolis/St. Paul.
You have not lived until you go outside when the temp scale does not matter. (-40 is the same in F or C.)
But remember when swimming up, exhale. Very Very important.
One of the counter-intuitive ways to die while diving.
Change your QBATCH max active job setting then... Or have your administrator change it. That job limit is not hard coded.
That would be a case of bad adminning.
Why do you need root to set shields? Worf's userid should be part of the security group...
Or in the GUI world....
Picard: "Raise all shields, 2/3rds power to the forward shields."
Worf:
Click on work with shields
Click on advanced properties
Clippy pops up with "I see you're preparing to defend the ship..."
Highlight the forward shields
Click on raise to power, roll the roller to 66%
Click on apply now
Click on confirmation box
Highlight the remaining shields
Click on raise to power, roll the roller to 33%
Click on apply now

Heinlein in "The Man Who Sold The Moon" had the same sort of idea too.

Yes, Dr. Jones Jr. does plug the dude with the sword in the DVD set. No bowlerization here.
Sirius Cybernetics Corporation anyone?
Like the talking trashcans at our local Taco Bell that say "Thank You" when you put trash in.

OS/400 Filenames and library names are 10 char (in the QSYS filesystem).
8 char filenames is a MVS/VM restriction.

They would revert to the old IBM name - Direct Access Storage Device (DASD).
It is the lower of density in the atmosphere.
Remember, HD heads "fly" above the platter -- if the air pressure (density) is too low, the head does not produce enough lift and will crash.
Most HD specs will list an altitude or pressure range where operation of the drive is supported.
