I wasn?t always free, so I know how it feels to work in an office.
Hopefully, you have a good seat.
But more important, and MUCH MORE EASIER is to change the habit.
You CAN go to the toilet, you can take every phone-call STANDING.
Now that I?m working at home, I still stand up at times to type something on a keyboard, or to think about a problem.
I get my best ideas under the shower, or, when I just stand up and walk a few meters in the room.
It?s really THAT EASY.
And remember, just because it?s easy, doesn?t mean it?s no good....
-
Having said that, here's my answer to your question:
NOTHING.
I want the doc's to have STABLE equipment, stuff I can rely on.
I know the feeling of not being able to move an inch way too good.
What you want as a patient is TRUST and CONFIDENCE.
You want to KNOW that the monitor measuring your heart-rate doesn't fail.
You are worried about air-bubbles in infusions.
You want nurses and docs to have TIME !!
Put a TV and a VCR in each patient's room, have some videos and headphones (!!!) ready.
Let a nurse come along every 45 minutes.
That's WHAT I REALLY WANT, HONESTLY.
And believe me, I really know what I'm talking about here.
Good luck,
george./
If you want to get Unix/Linux understanding,
buy this old book:
The UNIX Programming Environment, Brian W. Kernighan & Rob Pike, Pretence Hall Software Series, ISBN 0-13-937681-X. Do NOT worry about the age ! Unix is old !
If you want a fast solution for a specific question, gimme an email.
For your purpose, the German SCOPE program seems to be the best choice.
Contact the University of Karlsruhe and/or the City Hall of Duesseldorf, both Germany.
The data are processed to a 3D model, with extrapolation and accuracy scalable by you.
The program also generates output that can be used to control a movement over (or through) the terrain.
So it can be used for cruise-missile like steering.
It also makes it possible to extrapolate in time, to predict ground-water flow.
I had the "fun" to port this from a UNIX mini-super (2 PR1ME machines) to an IBM ES/9000 running MVS/ESA.
If you contact the City Hall of Duesseldorf, dept. of Environment, they sure can help you with data aquisition issues.
I worked in the central IT dept., and the department of environmental issues is using the program,
including gathering data from different sources with different methods.

- My experience (22 years on the job) showed that languages which are easy to use, are considered "childish" or worthless by the managment.
I wrote a connectivity (system) application using REXX. Two ES/9000 mainframes and numerous AIX workstations, access to DB2 from both mainframes (which were NOT coupled). Plus a fool-proof user interface that also worked around bugs in an IBM "user interface". I saw persons looking at the code, saying "looks like VB"...
I know that a US finance agency runs a complete system using REXX. I know how much trouble the developer at IBM had, to get her implemantation of REXX for IBM's AIX machines "official". (We used a free interpreter REGINA until the managment gave in.)
If something does look easy, it's considered worthless. What I wrote in 1000 assembler lines in 1979 could be written in 50 lines using REXX. But those 50 lines don't give you credit. Write 1000 lines and the managment thinks you're really hip, a real cool cat, a hoopy frood.
It's a kind of scripting language, but can be compiled to object code. It runs on Windows, Unix, IBM's/360 to/390, IBM's ES/9000, AIX, in short: Everywhere.
It has system calls facility. You can even choose what other system the call should go to (on a mainframe, that's important; on Unix it's not).
It is VERY easy to learn, yet VERY powerful. Some financial gov't in the US uses a complete REXX-written application. I used it for connectivity between mainframes and AIX workstations and almost everywhere.
The different interpreters are either free (for Unix, there's "Regina") or commercial (a very good one is from Quercus Systems for Windows).
Since the commands are very intuitive (that was the goal of the developer, an IBM employee) you can almost use it without any learning curve.
Kids - I guess - will make more use of system calls over time, and develop the special SENSE that either shows the talent, or does not.
Just keep in mind, programming can't be learned. You either have the talent, or you don't. But unless you let the kids check it out, you can't know.
- That was and still is (after 22 years) my goal. I think I reached it and I'm VERY HAPPY. You don't get the daily routine stuff assigned, you get the stuff that no-one else can do. As such, you automatically learn more, since you always get the tasks no-one else can do. Hence, you always are ahead of everybody else.
I saw a comment about money. This here is more worth to me than money, more than anything else. There are just two kinds of people: Those who want to be loved - Those who want to be admired. george./
- I've been working decades on the/360,/370,... up to the ES/9000 IBM mainframe architecture.
It would be going backwards to port Linux from the ASCII world to EBCDIC.
Even IBM's VM architecture is too esoteric, although it incorporates some features we find on Unix. (I see "Linux" as a "Unix flavor".)
There is NO point in creating some kind of emulation on an IBM mainframe running MVS/ESA, like an ES/9000 and the/390 do.
Or would you write an emulation to run IBM's EBCDIC on Linux ?? The system architecture is from another planet ! Believe me, I've been working on both systems long enough...
Warp drives and anti-gravity is NOT subject to NASA's research (this is the offical story).
The "universal conscisnous", observed in rats, is close to that "esoteric" water, which heals you because a molecule was nearby some time ago.
I always thought that was bullshit, but had to change my mind after reading some Quantum Physic stuff.
Take these two things together, and you have two facts, which might prove this discovery/theory. At least, they back it up somehow.
A person who thinks (happens at times) does emit electromagnetic waves. Does have changed (electric) resistance. See a polygraph.
Until now, no-one knows what the heck "the soul" is. Searching went on for decades to no avail.
Who's thinking here ? The brain or the soul (conscisnous) ? The conscisnous (never located in the brain) triggers the brain to think. How ? Ask God.
So if a poly works (and if you're in the US, you sure know at least one person who's ass was strapped to a poly), why shouldn't something else on the same principle work ?
Resistance (measured by a poly) does not exist without electricity.
Electricity does not exist without electrons. Electrons do not exist without atoms (free electrons were once bound to atoms, folks). Atoms do not exist without sub-atomic particles. Particles do not exist without the weak and strong force. Quantum Physic is an OBSERVING thing.
We don't know which state a particle has, unless we see a change. We don't "see" such particles, we only see interactions. That's how electron microscopes work.
If that particle loses his wave characteristic,..... no think for yourself.
Does that particle really HAVE a wave characteristic, or is it just simpler TO SAY it has one AT TIMES ?
We apply two different theories to the same phenomenon. Take light. Take quarks.
We only do that, because we don't really know the right theory yet.
We do however know, that a falling rice bag in china changes the weather.
So what's strange about a person's electro-magnetic emission and a sensitive receiver picking that up ?
I don't see anything strange here.
(Sorry for typos, haven't had enough cup~o~chinos yet.)
- I know a lot people who bought CDs at cheapbytes and later bought exactly the same stuff, to get the printed manuals. So do I. I need to look up something, and not changing the screen.
Here, you can "only" use telnet or ftp to get ON the machine. I've not concentrated on ftp yet, but I think an additional login-layer will help.
I use a root only executable (a script), that runs and prompts you for an additional "password". It's not killable, since trapped by "trap 'exit 1' 1 2 3 9 15". /etc/profile exits, if you kill this wizardcode-prompt, or if you give the wrong answer.
To get rid of that, you first have to be ON the system, to kill it. There's only LUCK to get thru this additional door. Script on request.
- From the site (DMM): >The memory intensive nature of object-oriented languages such as C++ and Java
From a reply: >why not make the hardware faster?
Fellow programmers, am I the only one who still remembers Assembler and the intensive search for memory preserving methods ?
Am I the only one who tries to make things fast, without thinking about the processor ?
In the 70s we struggled for every byte we could spare (yes, and we created the Y2K problem). "Star programmers" like me even changed the code during runtime, by moving new instruction over old ones. Yes, it was very hard to read, but it was top efficient.
Fellow programmers, are you all too young or what happened to the common sense ?
If I have to solve a problem for my daily life with my machines, I FIRST check if a SHELL SCRIPT can do it.
Not, because I'm too lazy to use C, but because it might be faster.
If you run The Shell, there are inbuild commands and external commands, some having the very same name.
Ie: A "test" runs faster than a "command test".
BUT, YOUR:
case "$1" in hello) COMMAND esac
RUNS *** NOT *** FASTER If "test" is inbuild in your shell (and it is, folks) and you write:
if test "$1" = hello then COMMAND fi Am I the only one who knows that ?
Java needs a lot of memory. It's hip. But what is Java REALLY ? Nothing than an interpreter language that just happens to have support by MS and Netscape (and due to this, now in our Linux kernels).
In the 80s we used (and I still do) REXX. It's also an interpreter language, can also be compiled to object code. It runs on MVS, VM, Unix, DOS, MS Windows.....
At that time, there were just no browsers (besides Mosaic). It can do everything Java can, the only reason why you guys and girls use Java is that Big Companies ship their interpreters with their browsers and it looks like, as if Java runs on it's own, like magic.
The only thing that runs on it's own is Assembler.
Now I don't want to say you should use Assembler, but I think I need to remind us all, that hardware becomes faster and faster, and that because of this, programmers get lazy and code stuff that runs on state-of-the-art hardware, but would run 4 times as fast, if these programmers would first think about RESOURCES.
A good program will run on a 486 in a reasonable speed and on a Piii like "real time".
I want programmers to THINK about how they code. It IS possible to write applications that do not need extensive memory and a fast CPU (or two), IF the programmer would first THINK about how to write something and optimize the code himself, not only with a standard optimizer (if he uses that at all).
Read "The Unix Programming Environment" by Brian W. Kernighan and Rob Pike. After that, your programs will run 4 times faster.
Replies greatly appreciated, fine day y'all, george./
- Here in my lab I also deal with intelligence. And artificial intelligence.
You are all invited to check out "Patsy":
A female cat, recognizes her name, recognizes multiple specific human beings and reacts accordingly.
Never falls, can even jump !
Special regenerative power supply lasts over 10 years.
Recognizes rooms, remembers places and even interprets a human's voice or behavior. The interpretation is stored in EPROM, so once she "understood" something, she will react faster the next time. To avoid stereotypic behavior, the stored information will be flushed if proven invalid for several times. That's what we humans call "learning".
"Patsy" can't speak yet, so bodylanguage is used.
There's only one string attached: She's copyrighted by God....
- the difficulties I pointed out are the same you mentioned.
How many folks have the time to recompile all their pgms ? I don't.
What is YOUR ADVICE for a LINUX-NEWBIE ?
Always re-installing new versions ?
I see this as a problem for Linux to get on more desktops, which is the goal of many Slashdot readers, isn't it ?
So WHAT DO YOU DO when XFree 4x, kernel 2.3, KOffice etc. come out ?
Do you upgrade your stuff for a week, or do you re-install, saving your data ?
What do you answer to a newbie who wants to run an application that requires a higher libc ?
Although I'm a pro, I want to USE my machines, not to be forced to upgrade every week. Maybe I'm getting old --- but that is also what new Linux users want.
And why they hesitate, because in a few months something better will be availabe. My answer is dumb: wait until the new distribution is out, then never read anything about improvements anymore.
Just when you buy a PC. A week later you find a better or cheaper one.
New users are not used to upgrade every month. They want to install something, and live in peace for the next 5 years.
I really think this is a big problem for Linux to go mainstream.
And I REALLY like to read your answers, thanks, george./

- And I mean EVERYBODY.
One year ago I thought such studies are nonsense. Then I read one from a nice chick at MIT. --- If someone is interested, I can search it to publish it here. --- Then I discussed it with a friend (a shrink).
LET's FACE IT: We deal with people and information in another way John Street does. And that's okay, we know more (news, weather), we experience more (discussions right here), we are way more powerful (information is power) than non-Netizens.
HOWEVER: Meeting someone F2F has an advantage. I alwayd denied that, because I didn't believe.
Since I'm absoluteley not the kind of guy who tends to socialize, I haven't changed my habits since I became a Netizen. No need to, there were no friends, I could saw less. And my TV doesn't miss me (okay, that's a guess).
I'm OUTING ME here, not using Anonymous Coward, so please give this a thought: REAL life Example: I have had 2 online friends who vanished. One is still there. I have one (in figures: 0x1) "in the flesh". That's it.
OH - NO - SORRY: I have a nice cat; she just learned not to tamper with all these computer/video/sound cables here in my lab.
So that makes 1 cyber-buddy, 1 real life friend and a cat.
OUTING: I thought this would be fine, -- but it isn't. No need to prove that, because my feeling tells me (what about your feelings, honestly ?). Yes, I admit I'm feeling lonely from time to time.
What I miss, is a non-commerical service to find folks. I don't go out unless I have a reason to, and where I live, there aren't much. And I rather program than seeing folks get drunk, or discussing the weather.
What about PROOVING that it is possible to meet new friends, with our "cyberspace" methods (what a disgusting word) ? Any ideas and suggestions ? Use email if necessary for not to blow up the comments here.
BUT, I'm ONLY taking MYSELF as an EXAMPLE.
What if WE, HERE, just proove the opposite ?
Would help all those who feel lonely but don't dare to tell it, and would add a GREAT thing to Slashdot.
The first volunteer for that (possible) work is: george./
- I've often been asked how to upgrade. You guys have the same problems and your comments are more or less THIS VERY QUESTION.
Now, there is no way if you ask me. And I think I know what I'm doing.
GLIBC upgrading ? -- Forget it !
LDP to the rescue ? -- Forget it !
WHY ? -- COMMERCIAL INTEREST.
You can not upgrade the C-libs on a RatHead 5.2 system ("you" is 90% of the folks who want to). (RatHead is an example, I think a good one regarding who many folks run the stuff.)
Download the GNU libc, and if you're in Europe, you could already forget about it, since EXPORT RESTRICTIONS applied. I tried it.
Have it, and you walk thru outdated, inaccurate documenation inside the libc tarball.
If you actually start and do it, you render your machine unusable.
The only way is - as one reader pointed out - to install a new distribution from scratch. I know A LOT OF PEOPLE who go this way. And they are not dummies.
If RatHead would make it easy, there would be an RPM to upgrade your libc. But RatHead wants you to buy their new stuff.
I don't know of a distribution with a reasonable pack of applications who doesn't go the same way.
And - there is a TECHNICAL PROBLEM.
If you compile all the applications in a distribution in a way that they need the libc at runtime, you would have to recompile every app you use. That's how companies (read: distributions) do it.
And YES, it IS the best way to handle programs, but it's also the best way to force someone to reinstall everything again (read: BUY AGAIN).
SOLUTION: Let the customer who buys a distribution decide whether to trade upgradabiltiy (nice word, hey?) for small apps, with better, overall performance (unless RAM is not an issue and your CPU is fast enough). Let him have the choice to have bigger programs (not dynamically linked) and the chance to upgrade the ESSENTIAL libc.

My experience (22 years on the job) showed that languages which are easy to use, are considered "childish" or worthless by the managment.
I wrote a connectivity (system) application using REXX.
Two ES/9000 mainframes and numerous AIX workstations, access to DB2 from both mainframes (which were NOT coupled).

I can however get a book, search the index (yes, my fellow hackers, good books do have indices),
and find it.
Ever bought a new MOTHERBOARD ???
Well, my latest came with a CD.
On that CD a dozen m/b's were described, GREAT HELP !!
SOUNDCARD ???
Yep - don't get the bass and treble adjusting working (neither on Linux nor M$ Windows), and the CD refers to A DIFFERENT card.
Folks, get real, we need SOME paper.
All I described above, no more, no less.
I won't buy a Linux distro without paper.
And that stuff is the ONLY paper lying around here.
Here, you can "only" use telnet or ftp to get ON the machine.
I've not concentrated on ftp yet,
but I think an additional login-layer will help.
I use a root only executable (a script), that runs and prompts you for an additional "password".
It's not killable, since trapped by "trap 'exit 1' 1 2 3 9 15".
/etc/profile exits, if you kill this wizardcode-prompt, or if you give the wrong answer.
To get rid of that, you first have to be ON the system, to kill it.
There's only LUCK to get thru this additional door.
Script on request.

From the site (DMM):
>The memory intensive nature of object-oriented languages such as C++ and Java
From a reply:
>why not make the hardware faster?
Fellow programmers,
am I the only one who still remembers Assembler and the intensive search for memory preserving methods ?
Am I the only one who tries to make things fast, without thinking about the processor ?
In the 70s we struggled for every byte we could spare (yes, and we created the Y2K problem).
"Star programmers" like me even changed the code during runtime, by moving new instruction over old ones.
Yes, it was very hard to read, but it was top efficient.
Fellow programmers,
are you all too young or what happened to the common sense ?
If I have to solve a problem for my daily life with my machines, I FIRST check if a SHELL SCRIPT can do it.
Not, because I'm too lazy to use C, but because it might be faster.
If you run The Shell, there are inbuild commands and external commands, some having the very same name.
Ie: A "test" runs faster than a "command test".
BUT, YOUR:
case "$1" in
hello) COMMAND
esac
RUNS *** NOT *** FASTER
If "test" is inbuild in your shell (and it is, folks) and you write:
if test "$1" = hello
then
COMMAND
fi
Am I the only one who knows that ?
Java needs a lot of memory.
It's hip.
But what is Java REALLY ?
Nothing than an interpreter language that just happens to have support by MS and Netscape (and due to this, now in our Linux kernels).
In the 80s we used (and I still do) REXX.
It's also an interpreter language, can also be compiled to object code.
It runs on MVS, VM, Unix, DOS, MS Windows.....
At that time, there were just no browsers (besides Mosaic).
It can do everything Java can,
the only reason why you guys and girls use Java is that Big Companies ship their interpreters with their browsers
and it looks like, as if Java runs on it's own, like magic.
The only thing that runs on it's own is Assembler.
Now I don't want to say you should use Assembler,
but I think I need to remind us all,
that hardware becomes faster and faster,
and that because of this, programmers get lazy and code stuff that runs on state-of-the-art hardware,
but would run 4 times as fast, if these programmers would first think about RESOURCES.
A good program will run on a 486 in a reasonable speed and on a Piii like "real time".
I want programmers to THINK about how they code.
It IS possible to write applications that do not need extensive memory and a fast CPU (or two),
IF the programmer would first THINK about how to write something and optimize the code himself, not only with a standard optimizer (if he uses that at all).
Read "The Unix Programming Environment" by
Brian W. Kernighan and Rob Pike.
After that, your programs will run 4 times faster.
Replies greatly appreciated,
fine day y'all, george./

Here in my lab I also deal with intelligence.
And artificial intelligence.
You are all invited to check out "Patsy":
A female cat, recognizes her name, recognizes multiple specific human beings and reacts accordingly.
Never falls, can even jump !
Special regenerative power supply lasts over 10 years.
Recognizes rooms, remembers places and even interprets a human's voice or behavior.
The interpretation is stored in EPROM, so once she "understood" something, she will react faster the next time.
To avoid stereotypic behavior, the stored information will be flushed if proven invalid for several times.
That's what we humans call "learning".
"Patsy" can't speak yet, so bodylanguage is used.
There's only one string attached:
She's copyrighted by God....

Interesting, that so many folks believe in telnet.
I thought I was the only one.
Now I would like to test my configuration, because I think it's bulletproof.
There is no encryption, no nothing. telnetd operates like "out of the box".
However, I added a security mechanism, that a some (older?) guys may know as the "wizard code".
With a one-letter-password,
I still believe no-one will be able to actually do an "ls" or whatever.
If there is interest, I can explain how it works and how you can install it (on a Linux/Unix system).
Even if you know the code in advance (with 2 lines left out), you will still have problems to successfully login on my main machine.
Anyone willing to take the challenge ?
Nice day Everybody,

the difficulties I pointed out are the same you mentioned.
How many folks have the time to recompile all their pgms ?
I don't.
What is YOUR ADVICE for a LINUX-NEWBIE ?
Always re-installing new versions ?
I see this as a problem for Linux to get on more desktops,
which is the goal of many Slashdot readers, isn't it ?
So WHAT DO YOU DO when XFree 4x, kernel 2.3, KOffice etc. come out ?
Do you upgrade your stuff for a week,
or do you re-install, saving your data ?
What do you answer to a newbie who wants to run an application that requires a higher libc ?
Although I'm a pro, I want to USE my machines,
not to be forced to upgrade every week.
Maybe I'm getting old --- but that is also what new Linux users want.
And why they hesitate, because in a few months something better will be availabe.
My answer is dumb: wait until the new distribution is out, then never read anything about improvements anymore.
Just when you buy a PC.
A week later you find a better or cheaper one.
New users are not used to upgrade every month.
They want to install something, and live in peace for the next 5 years.
I really think this is a big problem for Linux to go mainstream.
And I REALLY like to read your answers,
thanks,
george./

I have to correct something in regard to this reply:
I never said, or at least I never ment to, that statical linked systems, apps,... are better.
Of course I prefer the state-of-the-art dynamical architecture.
I just wanted to point out, how difficult it is to keep pace.
BTW, you CAN NOT download and upgrade glibc from RedHat.

And I mean EVERYBODY.
One year ago I thought such studies are nonsense.
Then I read one from a nice chick at MIT.
--- If someone is interested, I can search it to publish it here. ---
Then I discussed it with a friend (a shrink).
LET's FACE IT:
We deal with people and information in another way John Street does.
And that's okay, we know more (news, weather), we experience more (discussions right here), we are way more powerful (information is power) than non-Netizens.
HOWEVER:
Meeting someone F2F has an advantage.
I alwayd denied that, because I didn't believe.
Since I'm absoluteley not the kind of guy who tends to socialize, I haven't changed my habits since I became a Netizen.
No need to, there were no friends, I could saw less.
And my TV doesn't miss me (okay, that's a guess).
I'm OUTING ME here, not using Anonymous Coward, so please give this a thought:
REAL life Example:
I have had 2 online friends who vanished.
One is still there.
I have one (in figures: 0x1) "in the flesh".
That's it.
OH - NO - SORRY: I have a nice cat; she just learned not to tamper with all these computer/video/sound cables here in my lab.
So that makes 1 cyber-buddy, 1 real life friend and a cat.
OUTING:
I thought this would be fine, -- but it isn't.
No need to prove that, because my feeling tells me (what about your feelings, honestly ?).
Yes,
I admit I'm feeling lonely from time to time.
What I miss, is a non-commerical service to find folks.
I don't go out unless I have a reason to, and where I live, there aren't much.
And I rather program than seeing folks get drunk, or discussing the weather.
What about PROOVING that it is possible to meet new friends, with our "cyberspace" methods (what a disgusting word) ?
Any ideas and suggestions ?
Use email if necessary for not to blow up the comments here.
BUT, I'm ONLY taking MYSELF as an EXAMPLE.
What if WE, HERE, just proove the opposite ?
Would help all those who feel lonely but don't dare to tell it, and would add a GREAT thing to Slashdot.
The first volunteer for that (possible) work is:

I've often been asked how to upgrade.
You guys have the same problems and your comments are more or less THIS VERY QUESTION.
Now, there is no way if you ask me.
And I think I know what I'm doing.
GLIBC upgrading ? -- Forget it !
LDP to the rescue ? -- Forget it !
WHY ? -- COMMERCIAL INTEREST.
You can not upgrade the C-libs on a RatHead 5.2 system ("you" is 90% of the folks who want to).
(RatHead is an example, I think a good one regarding who many folks run the stuff.)
Download the GNU libc, and if you're in Europe, you could already forget about it, since EXPORT RESTRICTIONS applied.
I tried it.
Have it, and you walk thru outdated, inaccurate documenation inside the libc tarball.
If you actually start and do it, you render your machine unusable.
The only way is - as one reader pointed out - to install a new distribution from scratch.
I know A LOT OF PEOPLE who go this way.
And they are not dummies.
If RatHead would make it easy, there would be an RPM to upgrade your libc.
But RatHead wants you to buy their new stuff.
I don't know of a distribution with a reasonable pack of applications who doesn't go the same way.
And - there is a TECHNICAL PROBLEM.
If you compile all the applications in a distribution in a way that they need the libc at runtime, you would have to recompile every app you use.
That's how companies (read: distributions) do it.
And YES, it IS the best way to handle programs,
but it's also the best way to force someone to reinstall everything again (read: BUY AGAIN).
SOLUTION:
Let the customer who buys a distribution decide whether to trade upgradabiltiy (nice word, hey?) for small apps, with better, overall performance (unless RAM is not an issue and your CPU is fast enough).
Let him have the choice to have bigger programs (not dynamically linked) and the chance to upgrade the ESSENTIAL libc.
I don't see this happen in my lifetime.
This is the "Free Software" around Linux....

To both replies:
You overall agree, so there's nothing for me to answer to.
I just tend to be a nice guy replying to folks.
If this is offtopic,
then PLEASE someone from slashdot tell me so.
I'm new here, and I don't wanna waste space, nor do I want to ignore replies.
Fine Sunday Everybody,
