Because OO seems to be going down the same drain, too.
I have "upgraded" to version 3 a few days back. Then I did my first copy/paste from some web pages into writer, and was greeted by an explosion of dozens of post-it like notes all over the screen that told me that I just pasted all this stuff.
That was my second "WTF?? how to I turn this crap OFF !!!" moment I ever had while running Linux and FOSS.
(The first one being the screen blanking that always needs quite some fiddling to finally be completely off when I install a new box, since it always seems to be triggered from different places again in the console, Xorg, and the window manager)
Not necessarily. When something is wrong in an IT system, the cause for the problem very seldom is something that has to do with math or CS.
The main thing you need, in my opinion, (after the ability to read and understand plain-language error messages, which a lot of people seem to be lacking ), is the ability to "see" in your mind how different system interact and depend on each other.
Then you need to be able to figure out how to break a problem down and tackle one part after the other. Once you have located that $SYSTEM has $PROBLEM, then you can always Google if you don't know much about $SYSTEM or $PROBLEM.
I think much of *my* problem solving skills I acquired during my time as electrician, fixing industrial machines. Fixing them wasn't so different from fixing an IT system. See what works, see what doesn't work, isolate part with the problem, then dig into the documentation of that part if you don't know what's wrong.
They only ethical considerations businesses have is to their shareholders and owners to keep profit coming in.
Of course, a lot of companies forget that if you want to "keep profit coming in" for longer than a few years, you will need to keep both your suppliers and customers. The person you screw over today might be the one you need next year to make more profit.
One of the main difference between the Windows admins at work, and me, the Linux/Unix admin, is that when any big changes need to be done in off-hours, is that the Windows admins run around at work pointing and clicking and re-checking settings at night or on the weekend, while I just SSH into work and fire of the script I wrote and tested during work hours.
If the script takes longer sometimes because it has to change a lot of machines or a lot of data, I just keep an eye on it while watching TV or do games, or have some friends over.
In *nix, once you have figured out how to do something, you basically know everything you need to know to script and automate it.
In Windows, it is a huge additional step to figure that out and implement it, and it's not even possible all the time.
So on *nix you need to spend a lot more time learning stuff, but you spend a lot less time doing repetitive boring stuff.
For example, one Windows admin spend about six ours on a weekend at work to change the EmployeeID in AD to a new numbering scheme. Now I'm PRETTY shure that could have been scripted some way, even in Windows, but he rather did it by hand than try to figure out how to script it. Weird people.;-P
When ONE phone can create a da-da-daaa da-da-daaa da-da-daaa every few minutes in his radio, I imagine dozens of phones in a commercial jet, while not bringing it down directly, would drive the pilot nuts pretty quick.
And communication interference can be a cause for crashes, like in the 1977 Tenerife airport disaster.
I would estimate a communication interference at a critical moment is more dangerous to the plane than all the nail clippers that are not allowed on board any more.
Well, the good news is there is a proposed plan to bring rocks back from Mars, where NASA and ESA are expected to decide this November whether to go ahead with the plan or not.
They could also send the supplies / habitat first in unmanned automated mission.
That way they could land that, and see if the life support / hydroponics / water extraction / whatever "survives" the landing and starts working correctly long-term before sending the crew three years later.
Actually, what I heard from mechanics is that when you go downhill you use more gas when you press the clutch, since gas is needed to keep the engine running.
Any time your foot is off the gas pedal, and the engine is above idle RPM, the gas flow will be shut off or will be even lower than when the engine is running idle.
And engine breaking is way better for long downhill stretches than wasting your breaks using them all the time during the descend.
I have never encountered any *gaping* holes in the to_char/to_date documentation.
Granted, overlooking some obscure detail in the quite ramble-on-y Format Model specification linked from all the conversion functions ( which would go on over 19 pages if printed out ) is quite possible.
At least there you can still threaten your boss with "If you do $THING, then I will set the standard number format to Roman, and the standard Date format to Japanese Imperial";-P
Aside from the actual WORKING search functionality (which gives you a list in of "books" in which the search term occured with numbers of hits first, so that you can go to the relevant "book" when the search term is something ambiguous like "format" instead a long list of maybe or maybe not relevant links).
I never found the right thing on MSDN unless I stumble upon it via a Google search, Oracle usually gives the Description of a feature, some overview where it is uses and some examples with each feature. So once you are on the HTML page of the particular feature you are interested in you basically can get all the Information from that single page. Take for example a direct comparison between the commands to format a number into a string.
to_char (Oracle) found in about 20 seconds on the web page itself either by browsing by function or searching.
After two minutes I managed to get here in MSDN trying to find the command to format numbers in SQL Server, but haven't found the exact command yet, only an overview about "string functions" but the right one doesn't seem to be in this category.
I even know the command is "format".. something, but I cant browse there directly, since I don't know in what CATEGORY in those open/closable subdirectories they put it in.
The quickly scrollable and searchable HTML indexes of Oracle's online help are much easier to manage.
Ummmm.. There is just the small hitch that my special toner cartridge has run out just now. But if you send me $299 do refill it, plus an addressed and stamped return envelope, I have your working $1.000.000 check in the return mail right away.
We looked for a new junior admin, and one "test" we gave was an application not starting up, but giving a database error message. Which was pretty easily solvable by reading the documentation for the application and some light googling.
Which tested the basic necessity for IT: Think about a problem you have never seen before and try to find a solution. That test weeded out the ~75% of "Uuhhh.. sorry, I have never worked with that program before" applicants who would have needed hand-holding for years to come, even though they managed to get a long list of qualifications somehow.
I would count those software using "license servers" that check on startup and then deny startup of the application into the "license enforcement" category, not in the "license management" category.
On the other hand, we have one special software that doesn't enforce any license checks during runtime, but offers a "license audit" tool that outputs your concurrent users, maximum users, etc.. during a specific time period. That way you can check easily if you have enough licenses every now and then. And there is a condition in the license agreement that you have to check at least once a year. That is acceptable in my opinion.
Then as a bad example we have this other software that is a pain in the ass to get to run because they needs a hardware ID to get it to run. Thankfully we were able to fake that hardware ID in VMWare. Because it wouldn't fit in our disaster recovery otherwise.
In another topic people get worked up because ISPs advertise "unlimited" internet when in reality they try to enforce limits. That also can't be defended with "free speech", because it's not true.
In that case the ISPs also try to get an advantages by spreading false statements.
So the question really is, are the statements that were made about those women true or not. If yes, then the trolls should get off the hook, if not they should be responsible for the damages.
Committing some kind of fraud (Like telling someone "Yeah, that IS a genuine Mayan ash tray" and then selling it to him) also can't be justified by the free speech argument.
So to sum it up, we can agree that there is no gravitational convection, however there is some smaller Rayleigh-Benard and/or Benard-Marangoni convection.
Which means, to use "off the shelf" equipment they either need to check carefully how much it relies on gravitational convection, or add forced convection by fans or mounting the equipment in a place where additional airflow exist anyway.
In zero-g environments there can be no buoyancy forces, and thus no natural (free) convection possible....
The 2nd law of thermodynamic of course still applies, so the heat will eventually move away from the electronics, but much slower than through convection, where the heated air moves away and is replaced by cooler air. I would imagine it might be equivalent to enclosing the electronics in Styrofoam, which also keeps the air in place.
But there is no convection, since the heated air doesn't move "upward" like it does on earth. It hangs around the heated part without moving off, unless there is some sort of active ventilation.

He probably already HAD a career in banking, considering the schemes those guys came up with to generate money from thin air.
Gas is gas. Water is water. Sewage is sewage. You can't multiplex gas molecules. How can you have differentiated service?
Works that way here in Germany, too.
As you said, Gas is gas, water is water, etc.. so it doesn't really matter WHICH gas you get, just the AMMOUNT matters.
You have a meter at the place where the gas leaves the infrastructure (which is owned by an entire different company or the City).
The service providers have meters at the places where they put their gas into the infrastructure.
Everything else is (just) a matter of reading the meters right and bill correctly.

Interesting article, especially :

I would imagine it might be equivalent to enclosing the electronics in Styrofoam, which also keeps the air in place.
Nope. Why should it move, when there is no gravity to make hot air lighter than cold? Why would thermal currents form?
For example, they did experiments with candles. and they snuffed, because the hot air didn't move away and thus no new oxygen arrived at the flame.
