Re: [backstage] Make the primary OS used in state schools FOSS
I think FOSS can have a huge future but the community need to think about user experience then it will be taken more seriously. FWIW I've just come back from FOSDEM (open source community event in Brussels), and there are plenty of open source projects now putting usability at the top of their requirements list - and are hiring accordingly. These include Ubuntu, Firefox (of course!), Drupal and Mediawiki. Those are just the ones I know about. Hopefully we'll see some positive results in the coming months and years.

Single-point-of-failure risks are easily addressed, but 100s of individual machines will always be a pain :-( In many (most?) of the school labs that I have visited, half of the (Windows) PCs are not working properly - e.g. CD tray will not open - due to creative play from the students (e.g. constantly opening and closing the tray). A malfunctioning PC is an expensive piece of junk. A broken thin client at Skegness Grammar goes in the recycling, and a new one comes out of the cupboard: 30 seconds later it's up and running.

So think local. How many schols are there within 40 miles of you?= (by the way Richard, I believe we may have conversed before this evening, offline :) Thistle, last year?) Oh, there are many schools in my area. There's one about a third of a mile away from my doorstep! You seem to be saying that although the status quo is not good (indeed, it is delivering a second-cless education), there's no easy way out, so let's leave things as they are. If I have mis-characterised your argument, I apologise, but let's sidestep that. After all, you're barking up the wrong tree. You're somewhat on target; my final comment on this for the time being is that I think the current situation is far from ideal, but I freely admit that I have no fantastical solution which will make everything better. (the educational goldmine?) I know that M6-IT is somewhat unique in how it operates, including recycling legacy gear and giving it a new lease of life with quality FOSS to provide custom solutions that fit in where other proprietary solutions may not have worked as efficiently (it's a great thing!) - but M6 is also slightly different in its model, aiming itself as it does as a social enterprise for the voluntary and educational sectors. How many schools do you serve in your locality? (just curious...) Your model obviously works exceptionally well for what you do, but I wonder how big your client base is versus how big it could potentially be if you supported every school in the area - you could get very big, very fast, or the ground could open up for competition and aside from lower costs to the end users, there might be an even greater disparity in levels of support or the kinds of solutions delivered. I suppose the one sad fact about the current MS incumbency is that there can be some predictable level of consistency throughout the LEA. I'm fed up to the back teeth as much as anyone at some counties (including where my parents live) where the council has a massive arrangement with Dell - for the kind of service they get, they must literally parachute bags of money into Dell's UK HQ, and I think it's good money mostly wasted.

If you're talking about SaaS, the problems highlighted by Salesforce.com's recent downtime are testament to that - and as I'm sure you're well aware, school timetables and the National Curriculum have even less margin for troubleshooting IT than even the business sector. If I was a teacher I would hate it hate it hate it if I couldn't teach a class because the main host server was bogged down with too many intensive tasks, or it fell over or lagged out or needed to be failed over for some reason. There's a new build school in Bucks which is currently under construction; unfortunately it looks like not enough forethought was paid to the IT infrastructure so it becomes horrendously unfeasible, perhaps even impossible, to implement the kind of high quality, high bandwidth and low latency network a totally thin-client based network would require. (right down to simple things such as impossible corners for bundles of fibre to go round, poorly chosen rooms for network nodes in context of rooms where computers will be installed, and architectural features that can't have ducting run along them as it would spoil the visual presentation! So the fibre has to take a massively long route all the way around instead, hugely increasing the cost.) Of course, not every school is (hopefully) going to be designed like this, but it's not great... I think a lot of educational ICT systems have these kinds

bits and bobs snipped Note I'm not affiliated with these groups, nor am I a teacher, just showing that working, LEA-or-bigger SaaS *is* being delivered because of that better resourcing. It warms the cockles of my very being to hear that some organisations can get it right :) I wonder how much of it is mainly down to clueful people at the reins? BathNES seems to have come a long way... But then we in Wiltshire were always the poor relation to upper middle class BaNES ;) (lived in Wiltshire for 14 years when I were but a nipper :) BucksCC with the SEGfL is currently in the process of implementing a few gigs of storage (think it's 10?) + hosted email + docs + VLE + workspace for every single primary and secondary pupil in the county, with several years' retention and remote access, all the other gubbins... A truly titanic investment and development of infrastructure, which central Government /is/ paying for, handily. Every so often I ask about how it's progressing and I just get a weary look in my direction! I think in the end a proprietary solution /was/ chosen over the alternatives because it was just faster, easier and more beneficial to implement, having on balance the best interoperability with the other existing infrastructure and all the other essentials. I must ask the old man for some more information because I know things have changed since we last talked about it too. What is BathNES using for its base infrastructure? School network reliability aside, many Universities across the UK are deploying thin clients as we speak, my current employer (the University of Bath) has rolled out something like 400 in the past 12 months, without any significant problems. A number of other universities have had similar experiences. Bath are rolling out Sun Ray machines, as are, again, some of the other universities. All the components you mention above are probably equally as important - if the AD server goes down for a day and no-one can log in? Wuh oh. If the proxy is down and a teacher can't show the class the youtube video of a science experiment or get them to do some research for a project? Wuh oh. Yes, very true, my analogy works both ways. However, there's always the fact that unless something catastrophic happens to the authentication server (of which hopefully there's more than one if it's a large network) there's that much more of an incentive to get it fixed! In the meantime, if people are already logged on, hopefully the system will let them stay logged on because they already have validated credentials for that session. Thin client server goes down... Caput. I've witnessed my fair share of cockups and poor adminning at a network level as a luser in some of the schools I've been in (including some hair-tearingly frustrating ones... Classfuls of roaming profiles loading over a 100mbps network at the start of each lesson anyone?) but a catastrophic failure of some element of the network in a regular 'standalone' machine infrastructure won't be *quite* as catastrophic to the people who are currently using the system as if they were on thin clients... ... That said, do the Sun machines have some kind of stateful 'stasis' mode where the full state of each person's session is restored after a reboot of the host server? Of course if uptime is the #1 essential then you're going to have multiple host servers, but then you still need all the other bits and pieces AND you need multiple huge, sweaty beasts of machines to power the entire school's computing needs. And then you end up with compartmentalised networks, multiple host servers to look after in physically different locations... I can quickly see it becoming as much of an administrative nightmare as a sprawling standalone network. Pros and cons I suppose... I look forward to the time when thin clients become usable enough to fully replace desktops in some scenarios, because then we'll all get more desk space :D As a side note, I can guarantee Dave that educational software from five years ago that is essential in the classroom today does not run under Wine even now :) Can I put a fiver on that? I have a feeling that most schools would carry on using their existing setups regardless because it's too much hassle to change.
