My suspicion is that a lot of people are probably still running GNU/Linux (and
yeah, I messed up saying that the entire system was written by Torvalds; I
should have proofed better before publishing).


#33 of 79 by falcon on Thu Sep 13 20:37:24 2012:

Well, to answer whether or not people use GNL/Linux, in the scope of free
software it has the largest market share.  As for folks around here, I'm
guessing that more advanced users have opted for a BSD variant?

I know a guy who is very interested in unix systems and he recomended
DragonflyBSD as his personal favorite.  I actually have a USB stick with an
installation image from 2011, but as a new user I don't feel ready to venture
there yet, as ubuntu has a ton of community support for people like me who
are still learning.

Re. #33: I run NetBSD on some production servers.


#36 of 79 by falcon on Sun Oct 21 02:15:45 2012:

Interestingly enough, I also use the Xubuntu distribution of Linux primarily,
as with post #31.  This is probably related to the unusual choice by Canonical
to ship Ubuntu main version with an unconventional Desktop Environment.

One of my recent hobby projects is to get an SGI O2 machine up and running,
able to compile software.  An experienced Unix admin suggested I get NetBSD
onto it, rather then try to compile with the proprietary OS that it came with
(IRIX) which is obsolete.  It will be my chance to become more familiar with
NetBSD.

My current level of knowledge is such that it doesn't make much of a
difference which OS I am working on, whether it be Linux or BSD variant.  Bash
scripting should be the same for simple scripts.  I have a plan to check out
the three oldest Linux distributions, in order of increasing difficulty:
Ubuntu, then CentOS(RedHat) and finally Slackware.  What I will be able to
practically do with that knowledge is not determined, but I have little
planning in my life and a person has to start somewhere.

And finally, I suppose I will rise up to the level of knowing the importance
of differences between the OSes, and I can check out OpenBSD here, NetBSD on
my O2 (if I ever get it running) and FreeBSD somehow.  FreeBSD seems to be
the OS of choice for many free shell accounts out there, so it shouldn't be
a problem to find one for tinkering with, though for me right now I'm only
starting with bash scripts, so it doesn't matter which OS I am working with
right now... as long as I can script without fear of erasing my important
files with some silly mistake.

YOu can get a free NetBSD shell account at http://sdf.org.
Very reliable and a good internet connection but sometimes things get a bit
clogged.  I often have to wait 20-30 sec while writing emails.  $1 or so to
get verified gives you the use of a lot more programs (one time fee).

There are a lot of linux live CDs.  


#38 of 79 by cross on Sun Oct 21 03:34:32 2012:

Grex's span of life on OpenBSD is coming to an end: the new hardware will run
(indeed, is already running) FreeBSD.


#39 of 79 by keesan on Sun Oct 21 13:17:39 2012:

Can you explain why the change?


#40 of 79 by cross on Sun Oct 21 15:05:28 2012:

Yes.


#41 of 79 by remmers on Sun Oct 21 22:23:15 2012:

Cool. I look forward to the changeover.


#42 of 79 by remmers on Tue Oct 23 13:52:23 2012:

(And I assume there will be a more detailed and prominent announcement in 
Agora or Coop. I've been curious for a while about what's up with the new 
hardware and the changeover to FreeBSD.)


#43 of 79 by cross on Tue Oct 23 15:45:19 2012:

Yes.

In a nutshell: the new hardware is at Tony's.  There was (is?) a hardware
problem in the new M-Net, and I'm trying to set up both Grex and M-Net to be
as nearly identical as possible.

Most of the work now is configuration and documentation.  Almost everything
is actually installed, however.


#44 of 79 by remmers on Wed Oct 24 17:30:48 2012:

Nice!


#45 of 79 by ball on Sun Nov 4 23:41:44 2012:

    I think FreeBSD is a good choice, especially given the
history of Grex on OpenBSD and SunOS.


#46 of 79 by cross on Mon Nov 5 21:52:58 2012:

Yeah.  OpenBSD was a huge mistake, and the two who pushed it so hard are MIA.


#47 of 79 by walkman on Sat Aug 10 11:58:33 2013:

Do any of you think Linux use (not counting devices with embedded
systems)  is on the decline with OS X and iOS everywhere? 


#48 of 79 by nharmon on Sat Aug 10 15:16:39 2013:

Desktops? Yes.
Servers? No.


#49 of 79 by cross on Sat Aug 10 18:44:28 2013:

PCs as desktop computers in general are on the decline, so yeah; I agree with
Nate.


#50 of 79 by dtk on Sat Aug 10 20:10:09 2013:

In the server space, I can tell you that I have seen directly in both 
industry and Gov't it is growing and is a major platform for new roll-
outs, replacing mainstays like Solaris and HP-UX (and even AIX in some 
places). 

In the desktop space, it has a moderate share of a decreasing platform, 
so it is slowly shrinking with the rest of the desktop space. 


#51 of 79 by remmers on Mon Mar 24 19:25:59 2014:

Desktop space. Server space. Hey, what about the MOBILE space?  In the 
mobile space, Linux is growing by leaps and bounds. Any of the bazillion 
folks with a smartphone running Android is carrying (a heavily Googlefied 
version of) Ubuntu Linux in their pocket or purse.



#52 of 79 by cross on Mon Mar 24 20:13:19 2014:

Android has almost nothing to do with ubuntu.


#53 of 79 by dtk on Tue Mar 25 04:23:23 2014:

Resp:51 AFAIK, Android is a modified Linux kernel, which bootstraps a
JVM  and a custom java-based user-space in-lieu of init. It is only
nominally  Linux-based, and has little or nothing to do with Linux,
other than  pedigree. 


#54 of 79 by remmers on Tue Mar 25 13:44:11 2014:

This response has been erased.



#55 of 79 by remmers on Tue Mar 25 14:18:36 2014:

Ah, I appear to have been mistaken about the Ubuntu part. Was looking at 
this: http://elinux.org/Android_Architecture.


#56 of 79 by cross on Tue Mar 25 15:11:44 2014:

I've never heard of that site.


#57 of 79 by dtk on Wed Mar 26 02:13:39 2014:

Resp:55 Interesting. I'd not seen that, though it clarifies what I 
understood of the Android architecture. 




#58 of 79 by remmers on Wed Mar 26 12:39:27 2014:

Here's a capsule summary of the role of the Linux kernel in Android, 
written by Google software engineer Robert Love. Linux kernel with minimal 
changes, heavily redesigned user space.

#59 of 79 by cross on Wed Mar 26 17:27:13 2014:

Robert sits a couple of desks down from me; really nice guy.  Anything in
particular you'd like me to ask him?


#60 of 79 by remmers on Thu Mar 27 10:40:49 2014:

Please ask him if Chromecast is going to support Amazon streaming.

Oh wait, that's probably not his department. Never mind.

Anyway, the main point of my original response was that in gauging the 
extent of OS usage, nowadays you should consider mobile devices as well as 
PCs and servers, especially since smartphones and tablets are being used 
for many of the same purposes as PCs. And if you're willing to consider 
Android as a flavor of Linux, then Linux deployment is really quite 
extensive and growing.


#61 of 79 by cross on Thu Mar 27 11:45:30 2014:

I guess I've been thinking that for the last half a decade or so, so it comes
as a surprise to me that that's something people are only recently starting
to consider.


#62 of 79 by remmers on Thu Mar 27 15:31:43 2014:

Not too surprising. People are often slow to shift mental gears in the 
face of rapid technological change.


#63 of 79 by kentn on Thu Mar 27 17:31:40 2014:

Mobile devices have been starting to hit the business world more and
more in the past couple years.  Before that, using personal devices
for work may have been disallowed (e.g. keeping company files and
information on them, not cellphone usage which has been around for a
long time).  Now, it seems businesses are starting to acknowledge that
personal smartphones and tablets may have a place at work (maybe even
to reduce the cost of company-supplied devices).  So, that would be
why, for people who do not work at more liberal companies, it seems
more recent.  And by the way, no, I can't use my own devices for doing
work, even today.  That may change; however, for regulated industries,
the need to control company files would argue against it (absent any
security measures to ensure those files don't end up in the wrong hands
or change inappropriately when on personal devices).  So, this does not
surprise me.


#64 of 79 by cross on Fri Mar 28 18:59:20 2014:

resp:62 The iPhone runs a modified Mach/BSD kernel as well (that is, iOS
uses some variant of the XNU kernel).

resp:63 Please tell me you aren't using a motorola flip phone still.  :-) 
Put another way, I think it has less to do with what's going on in businesses;
this is about consumer consciousness.

Linux shows up in a lot of seemingly surprising places in the consumer space,
in addition to industrial and business uses, but its use is often unseen,
either by design or just because it's not something people stop to think
about.  Wireless "routers", switches, firewalls, etc; many of the consumer
boxes you buy at Best-Buy run some variant of Linux.  Same (I believe) with
some set-top boxes and the like.  What OS does your fridge run?  Would anyone
even think to wonder that (I doubt I would).  And apparently, Linux can even
make coffee: http://www.tldp.org/HOWTO/html_single/Coffee/#s2


#65 of 79 by kentn on Fri Mar 28 19:02:48 2014:

No I don't use a flip phone.  I have an Android smartphone.  I just can't
use it at all for any work-related activities.


#66 of 79 by cross on Fri Mar 28 19:06:03 2014:

But you know it boots a Linux kernel, right?  :-)


#67 of 79 by kentn on Fri Mar 28 23:00:28 2014:

Sure.  And having businesses provide or allow such devices just fuels
the demand.  So, that's why I mentioned it.   

Sometimes I want to go back to my flip phone, though :-)


#68 of 79 by ball on Tue Apr 22 00:57:04 2014:

    My LG Optimus has given me several years of good service
but the battery life has declined to the point where if I'm
not near a charger it will turn itself off before lunch
time.  It's also short of RAM and the processor's slow by
today's smartphone standards which hampers performance with
modern apps.  I have a company-issue smartphone that does my
work-related things (email, calendar, iperf, ssh etc.) so I
have been thinking of moving back to a simple flip-phone for
my personal use.


#69 of 79 by keesan on Tue Apr 22 14:54:26 2014:

Cell phone batteries can be very cheap on ebay.


#70 of 79 by kentn on Tue Apr 22 15:12:28 2014:

And they are cheap batteries, too.


#71 of 79 by keesan on Wed Apr 23 03:12:21 2014:

Mine for $2.50 works fine.


#72 of 79 by ball on Wed Apr 23 23:24:18 2014:

Re. 69: It has been years since I bought anything via eBay,
   mostly because of past disappointments there.  I
   considered a new battery but the phone has a some other
   issues that reflect its age.  I'm not complaining. It has
   given me good service over the years.  I'm quite tempted
   by the flip phone. My main reservation is that I wouldn't
   be able to use it as a WiFi hotspot on the days when my
   cable Internet connection isn't working.


#73 of 79 by keesan on Thu Apr 24 02:06:20 2014:

I just bought Jim a nearly new (returned in package) Virgin Mobile Kyocera
Rise for $20.50 including shipping.  It is very similar to what I paid $50
for last year but a year newer with Android 4 instead of 2.3.4.  For $12 I
could have had the same thing without the physical keyboard.  Wifi, GPS, voice
to text.  I am hoping he can use it to compose texts via voice.  It even has
a camera and speaker.  I have had very few problems with ebay, the most
notable being a Chinese American computer screen company that keeps listing
the wrong type of screen for our laptop.  They replaced it with another of
the same and show a photo of the wrong one and wasted their own money on
shipping both ways twice.  The $2.50 battery works fine.


#74 of 79 by ball on Thu Apr 24 02:33:48 2014:

    The flip phone I'm looking at is US$ 12 brand new.  I'm
going to miss being able to use the Internet while I'm
standing in the middle of a cornfield but it will suffice
for voice and text messages.


#75 of 79 by ball on Sat Sep 20 23:06:52 2014:

    I found the phone (a Samsung Entro) for $8 new
in Walgreens and was able to port my existing
smartphone account to it.  I get 300 minutes of
talk and unlimited texts for US$ 25/month.  I've
been pleasantly surprised by the reception and
audio quality and I charge it once or twice per
week.


#76 of 79 by keesan on Thu Sep 25 15:33:39 2014:

PagePlus gives you 250 minutes/month for $12, or 1200 for $30 with some data
as well.  Any Verizon phone.  But the support people at Verizon were unable
to help a friend 'program' a VN250 LG Cosmos that is known to work with Page
Plus - claimed it had no 'MIN' number to change.  $10/100 min (120 days). 
How did your garden do this summer?  No frosts here yet.


#77 of 79 by ball on Thu Sep 25 23:44:51 2014:

    If I change jobs and have to buy another smart phone for
personal use, I may be able to move my existing plan to it.
It has unlimited text and more-or-less unmetered data
(throttled after 2 Gbytes but not cut off).  I'm hoping to
hang onto this plan.


#78 of 79 by deejoe on Fri Jun 2 21:43:37 2017:

haha, cell phone discussion. Not that far removed from topicality, given that
Android uses the Linux kernel, at least.



#79 of 79 by ball on Thu Jun 15 03:03:06 2017:

If XNU counts as a BSD, then iOS is on-topic too.
