With both systems it's equally easy to get freeware on a whim's notice. The
difference is that in windows you get it from a site with flashing porn ads and

Hehe. Yeah, well, I guess it depends which sites you try to get the 
software from. And whether you use IE or something else...

Kewl.

"italic" is a different font, while "oblique" just means "slanted."

See this: http://en.wikipedia.org/wiki/Oblique_type

It's definitely easier to make a difference as an individual contributor.

It's also the case that even a small company can make a difference in 
Microsoft's stuff. Like the company that did the first defrag program for NT 
designed the APIs for that and told MS how to write it.

And I would guess security vulnerabilities found by an individual can get 
them fixed.

But yah, definitely not as *rewarding* as doing it in Linux. You'll 
certainly not get the sort of recognition for improving MS software, if 
nothing else.

Well, as I said, people want it for free, too. :-) Overall, they did a 
pretty good job with UAC, but it needed tuning. And people aren't that used 
to having to deal with it in Windows.  *Some* of what they do users don't 
want (like signed drivers) but MS does for their own good.

I was thinking more the DRM stuff, myself.

It's what Warp recommended to me when I needed to set up several dozen

It made the sysadmin annoyed, because apparently things are in somewhat 
weird places or something, so if you want to do something like bind two 
ethernet connectors so it uses both but falls over to the working one when 
one fails, it takes more work than with (say) red hat. But for a desktop? Go

Well, except for cutting-edge stuff. Different wireless connectors, or

*drivers*.  And if there isn't a standard windows API, there's usually 
custom software that comes with the device to do the thing. (Think about the

It is only popular for embedded operations as Linux, not Unix. Before Linux, 
nobody used Unix for embedded applications. Now it's popular for embedded 
applications purely because it's free. It's actually quite a PITA to use on 
embedded devices.

People who fiddle around with it without knowing what they're doing, yes. I 
think if Linux was as widely deployed as Windows, it would be just as much a

I.e., I think Windows is much less vulnerable now especially with UAC turned 
on by default, and what protects Linux is more that it isn't popular enough 
to be valuable to the current virus writers that do it for money.

Of course, Linux probably has fewer holes in the default distros than 
Windows does.  But it's not like there have never been holes in Unix-based 
OSes that, say, brought down the internet.

  There was one point in history when I had the opinion that if a game takes
more than 4 floppy disks (that would be about 5.5 MB), it's way too large.

  Nowadays I'm wondering why there aren't multi-DVD games yet in the market.

> Does anyone remember thinking "32 bits will soon be rather limiting for a

  There was indeed a time when a file of over 4 gigabytes was absolutely
unthinkable. This was the time when a 350-megabyte hard drive was huge,
and average desktop computers had 4 megabytes of RAM (which costed
significantly more than the 2 GB of RAM which is standard nowadays).

  Rather curiously, we are nowadays in the same situation with respect to
64-bit computers. Hard drives are about 500 GB, RAMs are about 2-4 GB on
average, which is about the same ratio as above. And again, a file of
2^64 bytes feels basically unthinkable (although slightly less so due to
the past experience).

  I'm wondering if 15 years from now we will be using files of that size.

I agree 100%! 4 years ago I could by an extremely good soundcard for 110Euro, 
and even better, it had a built-in motherboard!! ok ok, I'm talking about those 
Abit NF7S (or something like that) motherboards with SoundStorm onboard sound. 
Latencies of less than 10ms, without using ASIO.  Even my 300Euro Creative X-Fi 
Platinum (or whatever) doesn't come close to that
too bad they don't make those soundchips anymore

Don't be too sure of that, there are a couple free and good-sounding 
midi-players out there... can't remember the name for sure, but "midig" pops 
into my head...

Then they bought the company?

Or did they just make their own defragmenter and put it in the OS to ensure 
other companies selling defragmenters go out of business? :P

You should try Ubuntu Server, or maybe Debian, instead of the desktop 
Ubuntu. Or maybe you can tell Ubuntu not to install all the mess, I don't 
remember.

Ubuntu Desktop comes with all sorts of graphical programs that you may or 
may not need. It's better to install yourself what you know you will need.

Well sure. If you install a GNOME app in KDE, that will happen :) Instead of

zypper se mp3

Gave me a nice list of mp3-related programs on my openSUSE system.

Scan the list, and I see "LAME - Lame Ain't an Mp3 Encoder"

I wonder what that does:

zypper if lame

Oh, look, it's "an education tool to be used for learning about MP3 
encoding.  LAME is an educational tool to be used for learning about MP3 
encoding.  The goal of the LAME project is to use the open source model 
to improve the psycho acoustics, noise shaping and speed of MP3.  Another 
goal of the LAME project is to use these improvements for the basis of a  
patent free audio compression codec for the GNU project."

In other words, an encoder.

So add another 20 seconds to figure all that out. ;-)

	Sadly, not cheaper. But in a sense, it shouldn't be. By making an OS

	Sorry. Agree with Warp on this one.

	Maybe Windows stuff has changed a lot. In the old days, for a lot of 
software that had both a free and paid version, it was often nonobvious 
how to navigate the site to find the free version. All too often, I'd 
tell a friend "Oh, you can do that task in this software." And then they 
would report to me that they never tried it because it was only a demo 
(i.e. they didn't realize there was a free version).

	And still, you've got to go and manually download Winamp, and install 
it, and then remove the installer. In Linux, with a simple command, you 
just install it.

	And Winamp is overkill as an mp3 encoder. Can you use it with other 
software to encode the audio that software produces?

If you really want, I may install and support Ubuntu for 200 bucks. ;)  But
perhaps Ubuntu's official paid support is even cheaper...

sad thing is:  so far, I only got my ex-wife to give Linux a chance... and
that's for free!  Thankfully, I don't need to give much support, she found her
way with doing stuff just nicely.

I think they still license the defragger. The company is still around

It might have been that in Vista and later, but until then it was licensed.

Some folks write it themselves.

But no, that's kind of the point.  People use Linux professionally not so 
much because it's particularly good, but because it's licensed free, which 
is what you like when you have either 500,000 servers or you have a profit

I don't mind that. But a scanner program? I don't own a scanner, why

Well, you know, I'm trying to run a GNOME program that doesn't use 
sound, yet I'm still forced to install the GNOME sound drivers. (And 
sort out the mess when it expects a different kernel driver than the one 
I'm currently using...)

Similarly, ever tried installing Linux without network support? 
Apparently it can't be done.

Possibly. I haven't used Debian recently.

Back when I tried Debian (potato?), the (text-mode) installer would 
automatically launch dselect for you, or else install a default package 
set which gives you a bash shell and a few programs like "cp", and about 
nothing else.

That's what I use with KNOPPIX, yes... SuSE gives you Yast instead. And 
Gentoo uses Emerge. Whatever, insane package dependency chains are still 
common.

(E.g., try installing something that demands a different version of 
"glibc", and watch the anarchy that results...)

  Last time I checked, Windows costed hundreds of euros, while Linux was
completely free. I call that cheaper. Maybe your definition is different.

  But nowadays eg. Solaris is free too, and should be quite robust (as it has
a long history precisely in server environments). Also the different BSD
variants (but especially NetBSD, if I have understood correctly) are of
quite high quality (especially in terms of security), especially for server
environment.

  I'm not exactly sure why precisely Linux is so popular, given that most
software is not designed specifically for Linux, but basically everything
has been ported to other unix-style systems as well (especially the BSD
variants).

  Maybe it's because Linux has the most polished distributions which minimize
the amount of setupping and administrative work?

  A quick look seems to reveal that QNX (whatever it might be) is not free
for commercial use, so it doesn't really fit the no-cost part of my question.

Oh, I think those get used also. You could argue that the BSD variants are 
driving Apple's server clusters, for example.

Plus, people using Solaris or BSD don't necessarily tell you they're doing 
so. I've often heard "We use X inside our product, but we don't tell people 
that because it's a competitive advantage."

It could be that.

It could be that Linux is more friendly than Solaris or BSDs to people doing 
significant improvements and incorporating them into future releases. For 
example, if Google releases a "fall over from master to slave replica 
without stopping the server" improvement to MySQL, it likely it gets into 
future releases. That doesn't necessarily happen with MS SQL Server. I would 
suspect the same is true of improvements in Linux.

Basically, it's a network effect. Everyone uses Linux because that's what 
everyone knows in detail. It's good marketing, somehow.

When Google talks about map/reduce, someone implements it on Linux within a 
month. I don't know why they picked Linux, but probably because they already 
had Linux yadda yadda. So it's the same "unjustified" network effect you get 
with Windows - people pick Windows because everyone they know uses Windows. 
OS geeks hack on Linux because Linux is the platform where all the OS geeks 
hack. Computer nerds move to Silicon Valley because that's where all the 
other computer nerds live, which means there's nerd jobs to choose from, 
which means there's a big bunch of nerds to choose from, ...

QNX is a well-known RTOS that's quite popular. It's basically real-time 
Unixish. It's very portable.

At this point, such special systems are fading out, because even stuff as 
small as your phone is capable of running Linux.  Back when "embedded" meant 
8K ROM 1K RAM, it wasn't reasonable to have anything close to Linux on such 
chips.

As I understand it, the main use for RTOS is stuff like industrial 
robotics, where guaranteed timing is crucial. (E.g., you don't want a 
robot to drill a hole in the wrong place just because of a scheduling 
glitch.) It's not really for "personal computers", as such.

Yep. And video games. And media decoding. And a whole bunch of other stuff 
that interacts with physics including the time dimension.

> It's not really for "personal computers", as such.

I disagree. As I've said before, cell phones are extremely real-time 
devices, to the point of needing to know the temperature so they can adjust 
for how much that makes their quartz crystal drift.

You're not going to want a GC cycle to interrupt your playback of your CD, 
either. Etc.

When your machine has 5x the power it would need to do the job with 
dedicated software from the ground up, it's easy to load a 3x overhead 
factor in the form of a general purpose OS and still get it working OK.

That is a graphical program; as opposed to the command-line 'scanimage' 
tool.

Sure, but if I don't own a scanner, why would I want all the image 
capture libraries, CLI infrastructure and GUI front-end? Why can't I 
just skip downloading and installing all that stuff?

Rise of the Robots AGA for the Amiga.

14 disks. And such a sophisticated level of data caching that each time 
you get to the next level, you have to swap disks multiple times.

This is made up for my the game's delicious graphics. All of which is 
little consolation for the fact that the game itself SUCKS. It's like 
they spent so much time making lush graphics that they forgot to write a 
GAME...

2^10 = 1 KB
2^20 = 1 MB
2^30 = 1 GB
2^40 = 1 TB (we are here already)
2^50 = 1 PB (never yet heard of anybody except huge corporations 
reaching this)
2^60 = 1 EB (unthinkably vast)

 From MB to GB is "only" 1000x (or 1024x or whatever). From the GB or TB 
figures we're at today up to exabytes is a million times. But, sure, I 
guess we'll reach it eventually.

I wonder how much data you can physically store in a given volume using 
purely magnetic technologies?

That, and the fact that currently the only people who run Linux are 
geeky people with long beards who eat lentil burgers. These people 
probably know a thing or two about how to manage a computer securely. ;-)

(Although this is less true today than it was, say, 10 years ago...)

The idea is that for an RTOS, too soon is as bad (or maybe even worse) 
than too late. You need precise timing.

That said, if you have a machine under minimal load, it's less difficult 
to guarantee exact timing.

I don't think in one *file*.  One file system, perhaps.

Amazon has special rates if you're storing more than 5 PB, so it seems 
someone is.

Depends how you define "volume".  Think of the Google File System, spread 
over lots and lots of disks.

I was thinking in terms of available storage capacity. You can buy 
multi-TB drives now for half-sane prices.

Sure. Large comporations have reached here. Hell, if you put all the 
servers in my company together, it might total almost 1 TB. What I'm 
saying is that individual users typically don't store this kind of 
volume. (Yet.)

I was more wondering if magnetic spinning disks are soon going to lose 
the ability to increase any further in capacity, much like the way 
processors can't go faster any more.

I know several people who do - I've got over 2 TB of storage here at 
home, in fact - more than we had in network storage in a building serving 
1700 employees.

(A fair amount of it is really old data that I just haven't gone through, 
and multiple copies for backup purposes of some other data, mostly 
downloaded software for my Linux installs).
