Two products I came across while reading a previously linked article offering datacenter tips
- PlateSpin PowerConvert
The fantastic thing about these products is that they let you seamlessly migrate physical servers into virtual servers.
This is amazing stuff:
Stream servers between physical servers, blade infrastructures, virtual machines, and image archives over the network
Gone are the bad old days of Systems Admin where you needed to audit and plan every aspect of a server migration to new hardware. Even then it was so easy to miss something - particularly with Windows which doesn't offer much in the way of storing a running config - sure you can restore a registry but if you try that to different hardware you'll render the target system inoperable. Now the only risk is a virtual machine going 'stale' as it gets moved from one virtual environment to another. At least with a hardware refresh you're forced to look at what services can be dropped or how an install can be improved when starting with a clean slate.

Caught this over at John Siracusas Blog - Apple looking for assistance porting ZFS to the Mac
As John points out the performance overhead probably would preclude its use in consumer machines but for their server stuff it would be ideal. No point re-inventing the wheel for this type of thing if someone else has already done the work. As someone else pointed out hard-drives are getting to be so cheap its a wonder machines don't come with a mirrored pair for redundancy anyway.
For consumer stuff hopefully Apple can pull out a database driven file system like BeOS FS
used to have . . .

Monday night we joined the stream of people lining up outside the St James theatre to see Sigur Ros
I'd picked up their '()
' album about 18 months ago and had just recently picked up their latest album 'Takk
' which they were touring globally.
Luckily Karen saw that they were playing live back in January so we picked up tickets and organised roadtrip to see them. Figuring they were obscure and Icelandic I figured no one would be going to the gig.
How wrong I was - we joined a queue of several hundred people waiting to get in. The venue turned out to be standing room only front of stage but the seated positions were only a third full (tix were twice the price). Being an old fart with a healthy dose of tinnitus already I figured we'd go with the seated option. As it was the seats were designed for midgets and the legroom was atrocious making for a slightly uncomfortable gigging experiance.
Opening for SR was Amiina
- this quartet played a kind of funky playground instrumental thing. If you didn't see them on stage you would think you'd walked in on a music performance by a group of 8 year olds banging away on xylophones, bells, water-glasses, bowed saw and occassional violin/cello with PowerBook accompaniment. Actually a much groovier sound than you'd expect considering the instruments involved (kind of Tortoise-esque). Amiina also provide the backing strings for SR. You can listen to a track off their AnimaminA EP
. I think I'll be ordering this EP shortly.
Sigur Ros started and finished with an apocalyptic intro and finale backlit behind a huge gauze curtain onto which a suitably visually stunning lightshow was projected from various sources in the theatre. Very cool and the intro set the tone for the entire concert - pristine sound, volume was perfect and the songs themselves were performed beautifully. About the only complaint would be that the vocalist could be a little samey and it would have been nicer if the songs dynamics were left to do their thing sans vocals.
Thoroughly enjoyable and highly recommended - if you ever get a chance to see them play definitely go. One of the best concerts I've seen in years.
A much better review of them live is at Popmatters
Sigur Ros have a healthy appreciation for sharing music - you can download a number of tracks from their site here
. They also host an FTP site of fan-made audio/video recordings too
Now I need to get my hands on their Agaetis Byrjun
album . . .

Great post on the evils of Social Pressure
over at Gaping Void. I'd blow it up and print it out to stick on my wall but its sure to offend someone
Rob points to a WebOS article over at zdnet in his blog with some pertinant comments
. ArsTechnica points to the same article and links to another web based OS project that actually covers the basics rather nicely - Is there a WebOS in your future
Some annoying suprises in Microsofts Vista OS - Endless Security Warnings

Well I'm sort of job hunting again.
I've decided that when the interviewer asks the "is there anything you'd like to ask us ?" question I'd followup with "its funny you should ask . . ."
A selection from these questions should give you an idea as to how "switched-on" the organisation is with respect to IT service provision (and potentially the head-aches you might have to deal with if you work for them - then again fixing some of the issues might be what the role is all about).
Then again they might just think you're a smart-ass and not hire you as you may come across as a potential troublemaker
So in no particular order -
- What make / model servers do you use ?
- How old are they ?
- What hardware vendor maintenance do you have for them ?
- How often do you roll over old hardware ?
- Do you have a standard server build document / run book for each system ?
- How well are the IT systems documented ?
- What processes are in place to migrate services with minimal client impact (eg can you migrate your database server without having all the apps that rely upon it falling over) ?
- What critical services need to remain 'up' all the time and what provision is made should one of these fail ?
- What Monitoring do you use ?
- What Backup system do you use & how reliable is it ?
- How is storage provisioned and managed (do they have a SAN/NAS or consolidated storage plan) ?
- What Failover provision do you have for critical services ?
- Do you use data replication for critical information ?
- What services and applications rely on outside vendors or consultants ?
- Are there key services and applications that rely on any single persons expertise to work ?
- What call tracking system is in use ?
- Is there a change control process in place ?
- What is the induction process ?
- Is there a mentoring system to help you settle in and upskill ?
- Is there an on call component ?
- How often are after-hours alerts raised - what proportion of these can be handled remotely vs going onsite ?
- What SLA's are there ?
- What desktop OS do you use ?
- Is it a managed desktop (eg how is remote support, patching, anti-virus, software deployment, auditing handled) ?
- How do you rollout new hardware, software and services to the client community ?
- What access rights do people have and how is this managed ?
- What firewall, web proxy, virus / spam checking system is in place ?
- What remote access, vpn is in place ?
- What technologies do you use for your extranet / intranet ?
- Do you use a CMS (content management system) for your website ?
- Do you use an intranet, information is availabe to staff and who updates its content ?
- Do you use a DMS (document management system) for knowledge management ?
- What groupware system do you use ?
