In most organizations, if you use non-standard equipment, you're on your own, regardless of how high up the food chain you are.
So what your saying is... If I choose to imply that the word "Martin" means stupid fuck, then if I get enough people to go along with it, then it's okay to go around calling people "you Martin!" when I'm really caling them a "Stupid Fuck".
Okay - I get it now...
"You Martin!"
See - Definitions are there to give us a clear meaning of a word. If we start changing the definitions of words on a whim, then language and soon after society starts to break down.
Linux = Kernel.
There is no other meaning to the word.
I'm going to coin an acronym here and now...
LBOS (for Linux Based Operating System).
Now - from now on if we want to talk about an OS based on Linux (Kernel remember, the only definition for the word) - we'll say LBOS.
Repeat after me.... LBOS LBOS LBOS LBOS
If we can handle this, maybe we won't end up being such Martins!
As I've always said... Say what you mean, not mean what you said.
If they said "Linux" and not "Linux Distribution", then they meant Kernel, not OS.
I'm not a sore loser, I'm accurate and precise.
Linux is a kernel, not an OS. nuff said.
I've not maid an erroneous statement.
Martin has, and now you have.
Anyone who claims that the term "Linux" implies OS is mistaken.
I don't care if you get 1 billion engineers to claim otherwise, it's still wrong.
You apparently haven't worked with a T1 yourself.
Keygen doesn't even take a second to complete.
I've seen Oracle on a T1 outperform a Oracle on a high end AMDx64 (2xDual Core opteron).
Dear god? Patching? What kind of bullshit are you talking? Have you tried to keep 20 or 30 enterprise RedHat servers in sync for patches? Especially if you can't patch them all at the same time? Christ, you could run the up2date process twice in the same day, once in the morning, once in the afternoon and end up with different patch bundles.
You don't think that every other OS replaces patches or backs them out once a better one comes along? You're sadly mistaken.
Most config files (in our environment at least), are kept in a CM environment, even if a patch would overwrite a file (the only one that's ever been overwritten to my knowledge is a sendmail.cf and submit.cf), we could put our version back in place in seconds. The submit.cf and sendmail.cf are bad examples as they should auto-generate based on the ruleset defined. Most people just modify the.cf files and wonder why they are replace them.
As to security, Solaris boxes have been used as firewall platforms for years. Checkpoint being a prime example of this. I've never seen a whitepaper suggesting not patching and throwing behind a firewall... I call bullshit on that statement. Please include a link next time.
As to OpenSSH.... the T1 has crypto acceleration, that offloads the crypto work.
Not sure where you're getting your bogus info, but it definitely is not slow at crypto.

Hmmmm - what do I see here? WoW - The T1/Solaris blowing the doors off of the AMD/RedHat system...
Dang... I must be wrong and you must be right....
Bullshit...
Again... They aren't trying to make it more like Linux (the kernel)... They are trying to make it more familiar to the Linux users.
They aren't going to suddenly rip out the SunOS (or Solaris) components that make it uniquely Solaris (SunOS) - they are going to add features to make the transition easier.
If you're going to take everything at face value, then you cannot *ADD* distribution to the word Linux. The article says *Linux* not *Linux Distribution*.
Linux is a kernel - nothing else - saying Linux Kernel is saying the same thing twice.
A Linux based Distribution is an OS. Linux by itself is not, never has been, never will be.
To make a Linux distribution, you take the Linux (you know, the Kernel) and add GNU software, as well as a few other opensource applications and voila - you have an OS (yes, I'm glossing over all the fun and excitement of rolling your own distribution).
So - every time you say Linux, you are saying Kernel - period - there's no reason to specify Kernel after Linux as they are at the same thing.
To make it so that using Solaris is like using a Linux based OS, isn't making SunOS (or Solaris) more like the kernel.
Do you get it yet?
You were completely oblivious to the fact that everything I've said was right and that you didn't even realise you didn't understand the difference between an OS and a kernel...
Linux is not, nor will it ever be a distribution.
Calling a distribution Linux is a mistake. A common one, but still a mistake.
Get it?
Got it?
Good!
2 of the 6 are no longer around. The remaining 4 are quite active and running.
How is that showing any more bias than Torvalds comparing current Linux on current Intel/AMD to Solaris 5.6 on UltraSPARC II?
discount Stormix/Turbo - everything else still stands.
This includes RedHat Enterprise 5.
Correct, uname responds with SunOS for the system_name.
The key point I was trying to make is that one version was based on BSD, while the other was AT&T based.
The BSD based OS ran up to 2.5.
The AT&T based OS started with 5.6.
That would be Solaris up to 2.5, where it was based off of the BSD code base.
5.6 and above (yes, that's right, it's not 2.6, 2.7, 2.8 - it's actually 5.6, 5.7, 5.8), was actually based off of the AT&T SVR code base.
And, no, making something more Linux-like, does not equate to making something more like Linux, depending on the context of the term "Linux".
According to some, Linux is not just a kernel, but an ideal.
To make something in accordance with an ideal, does not make something more like a kernel.
However, to go even further... Their meaning behind that phrase is to make Solaris more *familiar* to Linux users. It doesn't necessarily mean, they want to go away from what Solaris is, nor should they.
They just want to make some changes so that those familiar with Linux can adjust to Solaris without the huge culture shock that Linux is to those familiar with AIX/HP-UX and yes, even older Solaris versions.
Sometime's Martin, it's better to remain quiet. Try and remember that.
Please feel free to continue to taunt.
And I'm not wrong... You can mimic someone' writings, but since I actually use the Operating system, and I'm not seeing anything that looks more like Linux than Solaris (and yes, I'm staying current with both production Solaris and OpenSolaris).
BTW - Making something Linux-Like, is not making something more like Linux.
There is a distinction. The distinction being making something the way Linux wants to be, not the way Linux really is.
Please continue, and I won't be going anywhere.
Taunt away.. I enjoy a good laugh as much as anyone else.
Single-threaded SPARC performance on modern processors is perfectly fine. In fact it's better than on Intel / AMD in that it's always the same. ie - it runs the same speed, regardless of load. It's throughput, not race to the finish, with long waits in between.
I've had horrible experiences with RedHat in particular, with modern, patched up versions blowing chunks due to patches loading, breaking either itself or other software on the system.
We've had systems that we've had to hack to get them to see all the fibre attached devices each time it booted.
We've had systems throw away LVMs and be unable to recover them. We've had them shutdown in the middle of the day because the drivers (albeit from the vendor) misread a thermal probe, and thought the CPUs were overheating.
They aren't making Solaris look like Linux, they are however, making Solaris cross platform (Sparc/AMD/Intel) - let's face it, there's only so many ways you can write code for Intel/AMD and have it work.
What they are doing, is emulating the OpenSource development model, seeing what comes from allowing anyone who wants to, work on OpenSolaris. OpenSource does not equate to Linux. Linux is OpenSource, OpenSource isn't Linux, it's not BSD, it's not OpenSolaris... It's just OpenSource.
Vegetable oil is NOT bio-diesel.
bio diesel is the result of refining, purifying vegetable oil, with additives like detergents, etc...
Pure vegetable oil is, I repeat, NOT bio-diesel.
FYI - My neighbor owns a bio-diesel plant. Trust me on this one.
SPARC Performance horribly slow?
Have you tried a modern SPARC processor?
I'm talking say an UltraSparc T1 here, not an old US II or US III processor.
Performance on web based applications with the T1 cpu blows the doors off of most Linux based OSes.
oh and "Linux code _is better_" - I'm sorry. Today's Solaris 10 is more stable, more capable and more compatible than any Linux variant I've ever tried.
Couple this with ZFS, Fire-engine, Containers/Zones and we've got an all in one solution to consolidation that runs circles around the Linux based varieties that we've tried. (TurboLinux, RedHat, SuSE, Ubuntu, Yoper, Stormix - and yes, I know some of these are no longer around).
Please, please, make certain of the facts before making such patently false claims.
Apple's just not that big of a slice of the pie.
If I were ATI, I'd say good riddance.
Please remember, each time Apple has opened the gates and *allowed* clones to be made, the clones have outsold, outperformed and outlasted the original Apple hardware, to the point that Apple had to *close the gates* as it were.
So now that Apple is using intel hardware, and commodity PC hardware for graphics, etc... how far are we from Apple only selling the OS, and not the hardware?
Possibly a bios change to the boot sequence, maybe even a bios options "UNIX/MACOS/WINDOWS" to set certain key features to the optimal for that OS variety.
Apple has come up with some glitzy designs, then hired out the lowest bidders to make them, resulting in sub-standard pieces of hardware in some cases.
The guy wasn't using gasoline or diesel. (Those are fuels named in the gas tax law, ethanol is in there as well).
Vegetable oil is none of these.
Where's the gas tax evasion? It isn't there.
Just because he placed the vegetable oil in his diesel tank, doesn't make it diesel.
They are using terms "fuel tax" when it's not written that way.
That's an if then statement, not an algorithm...

Get a small box, install opensolaris on it, configure your JBOD as either raidz or raidz2, configure either iSCSI or SaMBa to share the files using a gig link.
Your data should be perfectly safe, with raidz2 can lose up to 2 drives, without data loss.
I've been using ZFS for quite some time, and have yet to have any form of failure or data corruption.
I've used it with simple JBOD, SAN attached, even USB attached drives - it just plain works.
With Solaris 10 U3, and the latest revs of OpenSolaris, you have access to RAIDZ2 - which gives you double parity, even more protection.
Snapshotting can be scripted to run as often as you like. I keep 2 months worth of snapshots every 5 minutes day in and day out.
You can disassemble the system, scramble the drives, reattach and bring the system back up and all will be well. ZFS will just re-assemble the pool and continue.
You can replace drives on the fly. Let's say you make your 12 disk encloser with 750GB drives. Now, 2 years later you want to replace them with 2TB drives. Simply use the zfs replace command to replace each drive, wait for it to re-silver and rebuild the data on the replaced drive, then move on to the next drive. As you replace them, the pool will grow automatically. This would grow your (assuming 12x750GB in a RAIDZ2) 7.5TB pool to a 20TB pool, without downtime.
With OpenSolaris on x86, you can even boot off of ZFS now, so use ZFS to mirror your boot disk with a like drive and you should be good for quite some time...
Using something like Sun's Thumper system, you can get a 12TB system for less than 30k (for those who have something akin to a budget)
ZFS, it's fast, safe, secure - and I enjoy working with it (as I don't have to do much with it).
If the shop offering the free wi-fi service (free as in anyone can use), doesn't want it used outside it's shop, it needs to stop it at the walls.
Otherwise, it's fair game.

With OpenSolaris on x86, you can even boot off of ZFS now, so use ZFS to mirror your boot disk with a like drive and you should be good for quite some time... Using something like Sun's Thumper system, you can get a 12TB system for less than 30k (for those who have something akin to a budget) ZFS, it's fast, safe, secure - and I enjoy working with it (as I don't have to do much with it).
If the shop offering the free wi-fi service (free as in anyone can use), doesn't want it used outside it's shop, it needs to stop it at the walls. Otherwise, it's fair game. Free-public-wi-fi is just that.
