Joining the Netbook world

mbottrell@gmail.com (Matt) — Thu, 01 Oct 2009 12:51:00 +1000

I may be a slow adopter but I've finally jumped on the Netbook bandwagon.

I've been toying with the idea of getting hold of one of these beasties for a little while, and today a deal on Zazz! came up I couldn't resist.

They have the Asus Eee PC S101 for an amazing $444AUD. I'd seen them around the $999 price tag only as recent as March this year. (I think they are $599 RRP currently).

So in went my order.

Now -- what Netbook distro should I run on it (Windows XP Home is coming off immediately when it arrives).
I've looked at gOS and the Ubuntu Netbook Remix.

Any ideas/thoughts on the preferred Linux OS to run on such a beastie are greatly welcomed!

Pimp my Duck!

mbottrell@gmail.com (Matt) — Thu, 24 Sep 2009 14:50:00 +1000

Chris, a friend of mine has been able to do some fun electronics hacking for a worthy cause.

Chris has entered into The Great Brisbane Duck Race, a competition run by PA Foundation which sponsor the Prince Alfred Hospital. All monies raised will be used for Cancer research.

So what is the Great Brisbane Duck Race I hear you say?
Well it's not the infamous Ernie from Sesame Street rubber duckie:

In a nut-shell:

Purchase a rubber duckie from PA Foundation

Pimp your duck -- add a motor, jet engine, whatever you think is appropriate to make it the speediest duck around

Go down to the competition on the day

Navigate without sinking the 100m water course

Ensure your duck passes the line first to win!

Chris has been making some good progress, and been blogging about the project.

In fact he even has a YouTube video showing his current results.

The competition is being held on Saturday 26^th September at 2:40pm on the Brisbane River (in front of South Bank where the new Brisbane Big Wheel is located).

Whilst I won't be there in person cheering Chris on, I will be one of his virtual supporters!
If you're in Brisbane, head down for a great day and support such a worthy cause.

Flash your computer BIOS now under Linux

mbottrell@gmail.com (Matt) — Sat, 09 May 2009 00:19:00 +1000

FlashROM 0.90 has been released as part of the CoreBoot project.

That means you can read, write and verify almost all common BIOS chips now under Linux!
Gone of the days of needing to boot into DOS to Flash your BIOS.

So what does this mean?

Flash a running system, without needing to reboot. The new BIOS comes effective after a reboot (you can verify it prior to bouncing it).
Flash a remote system over SSH. No physical access required.
No need for a boot floopy or bootable CD to flash a system.
More than Linux is available. It is also available under FreeBSD, DragonFly BSD, Solaris, Mac OS X, and other Unix-like OSes.

Awesome work by the CoreBoot developers, and it means we're one step closer to removing any dependency on that other OS.

Linux Audio : Welcome to the spaghetti system

mbottrell@gmail.com (Matt) — Sat, 18 Apr 2009 03:13:00 +1000

Diagram of Linux Audio

Ever wondered why PulseAudio sucks so bad?

Sick of the multiple Audio stacks in Linux? (OSS/ALSA/PulseAudio).
Ever wanted to make sense of items like JACK,ESD,aRts and NAS or just confused with either GStreamer or xine?

Here is a clever overview of the sound systems that is Linux. (click the image for a larger view)/

Linux audio like it or not is a mess. Multiple layers providing the same functionality. It's a house of cards that often falls down.
Things have been hidden well in OSS/ALSA and it's not until demanding audio like HD codecs have started to make their way across that some of these issues are starting to be uncovered (the infamous 'popping' sounds).

PulseAudio has been poking and pushing ALSA in recent times, and as a result unearthed a number of issues.

I'm hopefully eventually we'll get to a single, simple but powerful audio stack. I'm not holding my breath though.

Mobile Internet for the entire household and universal mobile phone chargers

mbottrell@gmail.com (Matt) — Wed, 18 Feb 2009 01:27:00 +1100

Huawei, the Chinese company that ruffled a number of Cisco feathers have been pushing out a number of wireless 3G devices for wireless broadband for some years. You can find the Huawei devices like the E220 and E169 available from several Australian telcos for 'mobile Internet'.

I personally own a E169 on a Optus Pre-Paid Mobile broadband connection as a 'backup' for when my ADSL connection goes down.

This week at the Mobile World Congress being held in Barcelona Spain, Huawei has announced the release of i-Mo; a combined 3G wireless modem and Wifi router unit. This means one connection can now support multiple people.

Many people are already dropping a dedicated telephone line and the cost of ongoing line rental, such a device is certainly only going to grow this market more, as it can now move from a single user device to a household device.

However, the biggest news from the Mobile gathering is that we're likely to finally see a universal power adapter for mobile devices (so no need for a new charger whenever you upgrade that mobile phone). They are also suggesting up to 50% power savings when charging your phone. Don't hold your breathe, it won't become active until 2012. If only they could do the same with damn data connectivity cables!

Linux Printing - where is the fun in that

mbottrell@gmail.com (Matt) — Thu, 22 Jan 2009 04:16:00 +1100

Ahh the good ol' days.

I distinctly remember the days when you would stick a printer on the network and then wrestle with the sucker getting the right settings so your printouts didn't look like Egyptian hieroglyphics.
Installing custom filters and weird control files were all the norm. Not so much now.

Thanks to Michael Fox advice, I purchased a Brother Mono Laser printer this week (that handles Duplex/Networking as well). The Brother HL-5250DN works 100% under Linux and just required installing the PPDs off LinuxPrinting.org (though it was working fine prior to that just via CUPS and the included driver). What's even more surprising is that they have a Linux section on the Brother website.

I had the printer uninstalled from the box, read the 'setup instructions' included (plug this, remove that, etc), and had it printing duplex in < 10 minutes!

Before Michael's advice -- I had avoided Brother printers -- mainly due to having a PoS Brother plain-paper Fax machine. It seems their printers are much better than their Faxes.

So a big thanks to Michael.

So I ask Linux developers... stop making it so easy to install hardware. Otherwise everyone will be running Linux before too long!

Now -- I only need a bookcase in my office, and I've completed my new office setup!

Strange IRC messages from across the Indian Ocean

mbottrell@gmail.com (Matt) — Tue, 04 Nov 2008 20:34:00 +1100

Leave your IRC client set to away for a day, and then check your private chats later that night.

It's amazing some of the strange banter you get:

[someuser] hi..
[someuser] yesterday we completed the network config change in all servers, and now network part is clear
[someuser] ;P
[someuser] ;P
[someuser] :p
[someuser] please ignore above 3 lines

For the record, I was helping a fellow admin out with configuring a series of bonded interfaces for a server (7 connections - 3 bonded, one not).

I take it the first two lines of the message tells me it's been completed.
The next 3 lines were meant for someone else, whilst the last the user recognised what they had done.

The lesson for today: Check which window you're in before typing.

RAIDing the RAID

mbottrell@gmail.com (Matt) — Sat, 18 Oct 2008 03:44:00 +1100

In a not to distant past Russell Coker wrote about RAID Issues and referred in part to a report containing data from 1,530,000 disks running at NetApp customer sites. (also available in PDF or Postscript)

Interesting reading, for sure - particularly if you run any large dataset and want to ensure it stays intact!

It prompted in the recesses of my memory a report compiled in February 2007 by Google. The report, 'Failure Trends in a Large Disk Drive Population' was a report presented at the USENIX (FAST '07) Conference.

The Google report looked at actual hardware failures of disk Google saw over several years. The numbers were crunched (Is there anything else Google does besides crunch large datasets?). Some interesting results popped out:

The disks studied where either SATA or PATA consumer-grade disks that were either 5400RPM or 7200RPM ranging in size from 80G to 400G and been commissioned from any time after 2001. - Interesting this is the same disks that many of us will find in our own machines. No Enterprise disks, SCSI or SAS disks in the study.
HDDs had a higher tendancy to fail at the start of their life or anything beyond >3 years of use.
Low or Heavy Utilization of the HDD resulted in greater loss then 'Medium use'.
Disks that had surface scan errors had a greater result of failure over the next 60 days.
HDDs in operating in cool temperature (15-30^oC) had much greater failure rate in the first 3 years. Whilst disks > 3 years had a greater failure rate with the higher the operating temperature. The ideal rate for running disks to minimise failure rate was 30-35^oC.
A disk that spends more than 50% of it's powered on time > 40^oC is a good indication of a possible problem.
SMART data analysis revealed that it is not a reliable way to determine if a disk is about to fail. 36% of all disk failure had no SMART errors. The disks that had SMART errors the majority where seek errors (~72%). So basically, expect to see seek errors, beyond that you appear to be running blind with SMART.

Looking at both the Google Report and the NetApp Storage Report some 'best practices' become apparent to ensure you minimise your data loss:

HDDs are mechanical devices. Expect failure and plan for it.
Attempt to operate disks in the 30 - 35^oC temperature range to extend their life.
Monitor disk temperatures. Extended periods where a disk temperature rises unexpectedly (ie: not under any additional load than normal), is often an early sign that failure is close at hand.
Attempt to purchase disks not from the same batch. This will avoid a common manufacturing fault taking your disks out at the same time. (Many storage companies will do that for you as part of their service.)
HDD failure follows the Bathtub curve. The 'right side' of the bath kicks in around 3 years. Getting life out of your HDDs beyond that is a bonus, treat it as such!
HDDs are cheap these days. Don't be cheap -- implement RAID-6 over RAID-5 as a matter of course. Ensure you use Double-parity on your RAID-6 implementation. You'll find most recent versions of RAID-6 implement double-parity as 'standard'. (NB: If using NetApp - it's coined as RAID-DP.) Some vendors even allow you to upgrade the storage firmware online if using RAID-6 with Double Parity (NetApp for example has this feature).
Hot-Spares in your RAID-6 array is a very good idea. For the cost of the array consider it an insurance policy against the dreaded multiple disk failure which could potentially toast your array.
How important is your data? Can you put a cost on it? If the cost of replacement is extreme, consider redundancy options. This could include: Implementing RAID-60 (or RAID-6+0), archive/backup solutions, or even a total Disaster Recovery (DR) solution.
Air flow around an array unit is critical. Don't cram your arrays in a fully populated rack, as minimal air-flow will ensure. This will add to the HDD temperatures and general storage enclosure. Remember you're aiming to keep your disks at 30-35^oC.
Keep a logbook of when each drive was added/replaced. You know that 18 month disk then is less likely to fail than that disk that has been whirring away for 5 years. Record size, manufacturer and model/run. You may see some 'patterns' emerge in your own failure rates that will help with additional purchase decisions (ie: particular makes/models to avoid!)
Perform regular 'scans' or 'checks' of your HDD health, knowing the current state of disks allows you to plan for the inevitable failure.

Other tips I've picked up over the years looking after Enterprise systems attached to large storage arrays:

There is a reason that the ASX demands that publicly listed companies with 'mission critical' services for the public (items such as water supply, electricity/gas, and telecommunications) MUST ensure their 'mission criticial' applications have full Disaster Recovery operation on hot-standy.
Don't cut corners and not implement items like HotSpares and Double Parity. When you have a drive failure (not if), you'll be glade you spent that little bit extra on it.
A well planned storage solution should have drive failures, it shouldn't have storage failures. (Don't tell Sun/Internode that!)
Ensure you have clean-filtered power. Don't assume it. Power voltage fluctuations and disk writes don't play nicely.
Don't put all your eggs in one basket. Bad things do happen (I won't mention Internode again). Spreading your data out over multiple storage arrays helps add another level of redundancy. This is a GoodThing^TM
It's never a bad idea to have spare disks in storage waiting for that inevitable failure, rather than relying on a vendor to have your disk capacity/model available. Every day that dead disk isn't replaced you are putting your array at risk.
Look after your disks and arrays, and they generally will look after you (ie: ensuring you don't spend countless hours in the early mornings attempting to recover the unrecoverable!)

Above all, may your next disk failure not be a complete failure.

I'm interested to hear others stories, experiences and ideas that they have put in place to keep their data nice and cosy and their HDDs whirring in a constant and reliable state. Feel free to drop me a comment.

As a side note: I've been putting RAID-1 in place on my desktop machines as disk prices are so cheap now over the past 18 months. For the price of a few hundred dollars why bother the stress of a hard-disk failure? Having said that, it's no replacement for backing up your 'important' information. RAID-1 is still susceptible to the dreaded multiple disk failure issue. Having said that, I've been lucky at that hasn't occurred. (Touch wood!)

A visit to Ballarat this week

mbottrell@gmail.com (Matt) — Sat, 04 Oct 2008 04:35:00 +1000

This week saw me head to the Victorian regional city of Ballarat for a few days to undertake some RHEL5 x86_64 builds for work.

Whilst it's not as exotic a destination as an unnamed colleague visited nor did it see me returning without my pants or shoes ( sorry Jon, I couldn't resist! ), it was a productive visit.

Traditionally we undertake builds remotely, however these servers are likely not to appear on our network or even administered by ourselves, so it made sense to go onsite to undertake the work.

I stayed in the Doherty Ballarat Hotel and Convention Centre which literally is on the opposite side of the road to Sovereign Hill (and no I didn't have time to go there!)

View Larger Map

Whilst I spent most of my time in the office battling with hardware that had been incorrectly ordered (ie: missing hardware and/or non-compatible hardware (ie: 3.5" SATA drives ordered instead of 2.5" SAS drives for the internal enclosure)), I did venture back to the hotel in the evenings for some R&R.

The hotel room was quite pleasant, and what something a corporate traveller expects. There was no surprises out of the ordinary (which you really don't need when travelling), though I did have two strange nights of sleep due to external factors:

1^st night: Apparantly it's Koala mating season. Staying in a hotel room surrounded by forest is lovely to look at during the day, but it's also the playground for randy koalas of a night. So thumbs up to the 'big boy' who kept me up for several hours in the early hours whilst he ravaged the local female population. Koalas aren't dying out in this region whilst this bloke is still kicking! Seriously, I thought those types of noises I may have heard from other hotel rooms, not above my hotel room.

2^nd night: Local Football season must have finished. Seems some of the local players didn't head over to Bali to celebrate but decided our hotel was a great place to party.

In depth conversations at yelling level could be heard at around 3am. Answers to lifes biggest questions such as "Can you scull beer or bourbon faster?" were asked repeatedly. Finally after about an hour when it took that long for the gorillas to realise that they couldn't order a pizza to their room (and yes their was going to be surcharge for anything delivered to their room), the group of 6 decided that bundling into a car and heading down to the local McDonalds whilst tanked was the sensible thing to do.

I passed out after that, though it appears they were successful (if not foolish) as their car was there in the morning without any visible signs of damage. It seems the drink and driving campaigns don't apply to footballers.

I made sure I made enough noise as I passed their room at 7am heading off for breakfast, however in their drunken state the night previously, I doubt I would of woken them. It did bring me mild relief to my simmering frustration/anger from the previous nights interruption however.

The crazy and overpriced Internet costs in the room ($0.20/1MB with both uploads/downloads charged or $0.15/min) ensured I had a relatively Internet free week night. I really didn't miss being connected, though it did remind me how often I relied on just 'quickly looking up something'. Items like news, weather and even a TV guide via the Internet seems to have become the 'standard' method of information retrieval for me. It became more of an inconvenience than anything. I realised then that there was indeed a TV guide in the room. I gathered a quick round-up of news/weather using local radio. So this is what life was like prior to the Internet? (It seems so long ago now!)

Traditionally I use Google Reader to keep abreast of my feeds (as it allows me to bookmark, tag and share feeds easily), but being disconnected from the Internet was going to make that impossible.
I did however utilise a RSS reader, and was pleasantly surprised how easily it actually integrated into my Gnome desktop (particularly as it's a KDE app). The tray-icon and minimize/restore from tray all worked flawlessly (mostly due to the fact it's probably coded using FreeDesktop specs). I went with Akregator over Liferea after hearing reports that recent versions were prone to 100% CPU usage.

One thing I did notice, is that current RSS readers do allow for 'offline' mode - though it would be nice if it gave you the option of a 'full download' of certain feeds. Offline mode that only sucks down text is quite frustrating at times, as the associated image (being discussed in the article) isn't available. It feels like over-hearing a discussion you weren't meant to hear!

Whilst it's probably prudent allowing it to be set as a 'per feed' setting as I suspect many people may not want to download a full page for every article on every feed. (Particularly those feeds you only 'scan', and read a small amount of, or those that are overly heavy with graphics/flash, and embedded video.)

Since returning I did notice that Gnome also has the Straw Reader. Hopefully that comes along nicely as it appears to be in early development.
Ideally I would love to see an RSS reader that integrated WebKit with a good OPML import/export feature, as well as good support for RSS (0.91, 1.0 and 2.0), RDF as well as ATOM formats. Having a feature that allowed you to selectively do a full download of certain feeds for offline mode would be fantastic. I'll whack that down on my ever growing todo list (I think I'll need to live to 800 to ever complete it!)

One nice feature I discovered is the room had direct dial-in, and due to poor mobile reception in the room it was much more cost effective to have Pauline call me direct over VOIP. It also meant we could speak for much longer.

The staff I met at the Ballarat office were extremely friendly and actually quite enjoyable to be around. ( Sorry MrPointy, they were more cheery then you! ) They appreciated the effort I put in whilst down there (it's always nice to get some recognition) and appreciated the attention to detail. It was quite good timing as I will relocate offices to this one once I move into our new home (probably 4-6 weeks away). Heading into the Ballarat office is much closer than the Melbourne offices from Bannockburn. I've already made some good inroads into getting to know people there. I'll be the only member from my team at this office location, so it makes sense to build some bridges.

I did add two things to my 'travel-list' when travelling for work:

A cheap mini 10/100 switch.
This is invaluable when you're stuck in a room with one Ethernet port attempting multiple server builds, and also wishing to have your laptop online at the same time. I headed out the first day a picked up a cheapie TP-Link 5-port 10/100 Switch. Cost me $20 from a local computer store, but saved hours of frustration.

A decent power board with surge protection
In hindsight I should have also taken/purchased a decent power board. The room only had 4 power outlets which meant I could only have one server up at a time. It would have been nice that I could have multiple machines up at the same time, as these were identical builds (besides their hostnames), I could have used something like clusterssh to undertake the same tasks across all the machines at the same time -- ensuring I could have finished the job in a fraction of the time.

We live and learn.

The Linux Foundation speaks for no-one.

mbottrell@gmail.com (Matt) — Sat, 27 Sep 2008 04:14:00 +1000

I was appalled after reading the rather rash statements made by Jim Zemlin the Executive director of the Linux Foundation.

His rather bizarre statements against Sun (who is also a silver member of the Foundation) must have left many execs in Santa Clara scratching their heads and wanting some answers.
What's worse is the story originally ran in InfoWorld, then was picked up by the New York Times. Other notable online sites also ran with it, including Slashdot and LWN to mention just two.

Lets look at some of the statements the Exec Director of the Foundation made:

"The future is Linux and Microsoft Windows, it is not Unix or Solaris."

Solaris has almost no new deployments and is a legacy operating environment offered by a company with financial difficulties. Original equipment manufacturers also do not see a bright future for Solaris. This was paraphrased and not a direct quote.

Sun, he declared, should just move over to Linux.

"It's certainly true that Unix is on the decline." - Discussing IBM AIX and HP-UX

"The only people I hear talk about DTrace [Solaris's technology for assessing program and OS behaviours] and ZFS [the Zettabyte File System] as competitive features [are] Sun Microsystems sales representatives. It's not something I believe is impacting the market in any way."

"...With capabilities such as ZFS and DTrace, Sun is trying to compete based on minor features", Zemlin says. "That's literally like noticing the view from a third-story building as it burns to the ground."

Zemlin, on Sun's open-source Solaris as "too little, too late." He also goes on to claim that there is no real open source community around OpenSolaris, arguing that Sun still controls development

Open Solaris is no more than an attempt to expand the Solaris user base to drive customers to commercial Sun technology.

Seriously where does the guy get off?

Looking at his profile on the Linux Foundation it doesn't instil a level of confidence.
A former Exec at Free Standards Group (who with the OSDL merged to become the Linux Foundation). He was also VP of Marketing of Colavent Technologies (basically a crowd that sold commercial Apache support amongst other things). In 2000 he was a board member of Corio an ASP, that had an IPO then was sold off in chunks. IBM retains the http://www.corio.com/ URL.

So, from my reading he's got quite a bit of marketing/exec background for web-based application servers.... beyond that, I don't see any real technical prowless. He's a marketing suit that appears to shoot from the hip.

Let's review some of his "quick-draws":

The future is Linux and Windows?

WTF?! Did you take crack before taking the interview?

Sure as the exec. director of The Linux Foundation we expect you to come out and say "Linux is the future" - but to throw Microsoft in the mix -- you have to be kidding me.

Look at general stall that Microsoft has had with Vista. They have forced OEMs to install it, and even some of the larger ones now have kicked back and offer corporations and high-end consumer devices the option of Windows XP instead.

No major deployments of Solaris... and disliked by the OEMS.

That must be news to both IBM and Dell, who offer OpenSolaris on their x86 series servers.

As for a company in 'financial trouble' this is an extract of the letter to shareholders attached to their latest Annual Report /10-K filing to the SEC (Read it online here).

I've included a screenshot the opening paragraph of the letter:

That doesn't sound like a company in 'financial trouble' to me.

You can see this on their Consolidated Statements Of Operations

The decline of Unix (Solaris, HP-UX, AIX).

It's interesting to note that all of these make hardware as well as an operating system. These systems normally scale much larger than that of a traditional Linux server (excluding clusters). Take a look at Sun's M9000, IBM's p5 595 and HP's HP-9000 Superdome Server. These computers can replace dozens of Intel based servers and thus are not something companies run out and buy dozens of. (well normally!) Interestingly... both HP and IBM are also Platinum Members of the Linux Foundation. With a Platinum membership of $500,000USD each. How's that for biting the hand that feeds you (literally in Zemlin's case).

The I/O throughput and disk-subsystems available for these machines normally far outstrip that of anything under Intel/Linux range.

ZFS, Sun Zones/Containers and DTrace.

Seriously you jest Mr Zemlin?

Linux virtualization is still a mish-mash under heavy development. (take Xen, KVM, LVS and even Sun's VirtualBox)... I wouldn't class as enterprise ready. Hell, even VMWare that started in Linux roots, has moved over onto their own kernel. Zones and Containers under Solaris are much neater and better suited to an enterprise environment.

As for ZFS -- Linux has no mainstream file-system that competes. The size of volumes and the ease of use leaves ext3 behind. Even the upcoming ext4 has no real claims over ZFS. For large scale filesystems, ZFS has it over native Linux filesystems.

DTrace - ask any administrator of 100's of Linux servers if they think DTrace is a minor thing? Sure Systemtap is nice, but the comparison of Systemtap to DTrace still shows some deficiencies. Being able to trace safely on production systems is a requirement for something that can be used in the real world. Add to it the ability to trace user-space programs and DTrace does indeed have some features many SysAdmins discuss and would love to see under Linux.

Sun's open source Solaris 'too little-too late'. No community, still controlled by Sun.

Wow... I wonder if he would make the same statement if Microsoft released their OS as open-source? Open-Solaris is a community site, though Sun still controls it. There is nothing wrong with that. It's their baby, and they can do with it what they like.

Sun is still a large OSS backer.... remember products like MySQL, Innotek/VirtualBox, and hey, they even OpenSourced Java.

Sun have shareholders to consider, and they need to make a return on their investments / R&D. I don't really have anything bad to say about the CDDL. It makes sense for them... and hey something is better than nothing. What I find hilarious is that many Linux advocates will bag the CDDL, but love Mozilla. Wake up people... the CDDL is based on the MPL! The CDDL is also recognised as a license under the OSI.

Open Solaris attempts to drive customers to commercial Sun technology

Actually most of the people I've come across it are already using the commercial Solaris or wish to learn Solaris. OpenSolaris is a nice way they can install it at home and come familiar with the environment outside of work at their own pace. It makes sense that they can utilise the same operating system in their work-place and in the comforts of their own home.

For me, I'm a fan of Linux. I love the breadth of software available to me, the rich and colourful community around it. I have grown up watching Linux (I first compiled up an 0.54 kernel on a lowly 286). My servers and desktops/laptops all run Linux.

Having said that, I learnt *NIX on SunOS and later Solaris. It has it's place, even in today's world.
I agree, the low-end UNIX servers are often replaced by Linux servers, yet there is nothing really in the Linux space that competes with the high-end UNIX environments.

A lot of what we see in Linux has it's roots in commercial UNIX. (Hell, who has networked file systems in their environment that doesn't use Sun's NFS?)

So take some advice from a Linux admin at the coal face. Linux co-exists well in a heterogeneous environment, sharing the space with commercial UNIXes and even those annoying Windows servers.

If you need to beat up a 'Server OS' next time Zemlin, try attacking Microsoft (Hint: they are not a member of the Linux Foundation).

Linux servers have probably dented more Windows server sales then that of commercial UNIX. Samba has played a large role in that.

Exchange is probably the last bastion of Microsoft dominance. With the amount of Exchange 'replacements' now on the go that run under Linux (ie: PostPath, Zafara, OpenGroupWare, Scalix and Open-Xchange to name just a small fraction of those available. ) It's likely more inroads into the proprietary walls of Microsoft are now showing cracks in many corporations. Many IT managers are struggling to justify the outrageous price they get slugged for Microsoft Exchange, and these cheaper and feature-rich alternatives are often fractions of the cost if not free.

So next time you attempt to speak for the 'Linux Community' Jim Zemlin, try actually speaking to some Linux administrators that live in the Fortune 500 world. We aren't all hippies yelling 'free OS love'. In fact we happily co-exist with commercial *NIX and sometimes even Windows servers (much to our disgust).

Leave your "Us vs Them" mentality at your door, it's not a view held by a large proportion of the Linux community. Indeed many Linux administrators actually also administer other commercial *NIX machines in their day-to-day jobs. There are more similarities between the commercial *NIX flavours and Linux than not.

We do realise it's part of the Foundation's role to 'promote Linux', but keep the mud-slinging and crap out of it. Let Linux stand on it's own technical merits and not at the detriment of dragging another 'cousin' down in the process. We see enough of this style of 'marketing' from Microsoft that we don't need to stoop to the same levels.
