Not a patch on Infra-Black
(And now I go reading the comments I see I'm not the first. Not that I expected to be.)
Re: Wireshark maybe
These are all good questions which can be summarised by the question: "What is your aim?"
Do you want the info for troubleshooting? Compliance reasons? To catch someone you suspect of doing something naughty? How you answer these should dictate how much importance you put on each aspect of the task.
For instance if you're trying to understand who is using the most bandwidth and which sites they're using then it MIGHT be a better solution to upgrade to a router/firewall that can gather these statistics for you if you don't have one already (I haven't read the other article yet). Most home routers these days and certainly the lower cost 'business' routers seem to have this functionality.
You might find that your firewall/router also has the ability to do more detailed log capture/packet analysis and send the results to a log server which could be one of the internal PCs which you SSH into and SCP the files from OR you could get it to log to YOUR server, wherever that might be.
There are many options. And the more I think of it the more I can come up with but the key question remains: "What is your aim?"
I know you said "...Installing a server to do the sniffing probably isn't an option..." so I'm going to take the 'probably' bit and run with it. Also, in the time it takes me to type this up ninety-eleven other people are bound to have said the same thing.
I think this is probably exactly the kind of thing a Raspberry Pi running Wireshark would excel at. It'd allow you to SSH in to SCP the dump files for analysis, it's small with low power requirements and importantly it's very low cost.
It's true though that if you wanted to capture ALL traffic on the local layer 2 segment then you'd have to have (as I understand it) a switch that can mirror traffic from other ports to the one the Pi is attached to otherwise all you'll be able to pick up is broadcast traffic. Also, with regard to inbound and outbound traffic you'd need to find a way to use the Pi as a router and pass the out/in bound traffic over NICs attached to it which would mean using a USB to Ethernet adapter and I have no experience using one of them with a Pi.
I believe to train drivers this means 'Signal Passed At Danger' (i.e. jumping a red)
Which fits here too.
No mention of the length of a piece of string?
I used to do some IT support for the boffins at NPL (and I'd like to take the opportunity to say what a fantastic bunch of chaps and chapesses they are!) and the one thing that I found amazing was they could - and WOULD - measure anything.
I think the story goes like this (I heard it Nth hand): One of the boffins asked one of the designers how long a brochure or leaflet or somesuch would take to complete "Oh, well, how long is a piece of string?" came the reply. About a week later a small wooden box was delivered to the head of the design department containing a piece of string and an official certificate saying something along the lines of "A piece of string. Length: 97.914mm" and a typed note saying "So, how long until I get my brochure?"
The story may well be apocryphal but I have a photo of the piece of string in its box and the certificate somewhere. (Though I may have misremembered the exact length, it was to 3 decimal places!)
What a wonderful bunch!
Loading disks on a Mac
Listen up, this is IMPORTANT people. What you need to do is disable Mission Control's use of f12 to bring up the Dashboard. SO pop on over to System Preferences>Mission Control and from the popup menu next to 'Show Dashboard' choose the -
Then, to load the disk you've selected in the emulator press - by default- [shift]-[fn]-[f12] OR if you've selected 'Use all F1, F2, etc. keys as standard function keys' in System Preferences>Keyboard, you can leave out the [fn] key press.
Pies, Ham Pies and Statistics
I'm no expert but...
On a cursory read-through it does seem to me that they're not normalising (or whatever you want to call it, I did say I'm not an expert) their data before doing an analysis of it. This is bound to throw the numbers off somewhat.
Also, what others said above me, the duty cycle and usage hasn't really been taken into consideration.
I'm Brian, and so's my wife.
Except that she had problems and I didn't.
Now if only there was a stop/go icon.
"Common Sense" (not all that common and not always sensible) says to me 'Not practically or cost effectivly with current tech'.
If you were able, like IBM, to manipulate things at the atomic/molecular level then 'maybe'.
Only just this morning I was reading this...
There's so much egg on his face he MUST have been yolking!
What? It wasn't that bad a joke, was it?
(Thanks for the thumbs ups!)
I should point out that far from being the abject failure the (now deceased) teacher predicted, I'm IT Manager at a large company and am doing pretty well for myself.
Re: Me Too
This, to the power of eleventybillion!
We need an "El Reg Unit of Agreement" that I can use here.
Re: So how would one request you to cease speaking on a topic?
I tend to tell people that if they want me to stop/change subjects to tell me firmly that 'That's enough of that subject". I'm not going to be offended as I KNOW I go on but you have to be clear about it and say what you mean as if you use a euphemism or just hint at it I'm really unlikely to notice.
After 40 years of not quite getting 'life' I was finally diagnosed with Asperger's last year. And was promptly sacked when I told my employer. (that's dealt with, amicably).
So now I'm back to square one with '...[he has] no valid excuse for his behaviour and actions other than being a bloody minded, stubborn hellion of a child who will find no place at this school or in society if he doesn't buck his ideas up very quickly indeed..." as one teacher so eloquently put it when I was 7.
It's too hot for a coat, I'll just go, then, shall I?
Again I'm amazed
That disk failure can cause such a problem. Do you not make sure that your data is replicated across multiple storage devices/sites/tapes/whatever? You might call it backup, archiving or simply 'making a copy' but don't these people think in terms of full redundancy of complete datasets?
Yes, I know the bean counters don't like it, but isn't being laughed out of the business worse than spending the money to ensure you have a stable platform on which to offer your services?
I often think in cases like this it must be much more than a failed disk or 3.
Add a ; for fun
At the end of line 10 and instead of it printing:

(at least BBC Basic did and I think the Speccy was the same)
Re: As a friend of mine put it..
Then in that case there's a perfect ascii representation of; this comment, ^ that comment and v that one, too.
Even to the pyto I just made and the rong spelling and bad grammar.
The infinite nature of π has a lot to answer for!
Re: Local caching?
I'd guess two things factor in that. 1) Cost and 2) Licensing.
Running a bunch of caching servers and the associated storage 'locally' on their network will mean they have to pay for the kit, pay to put it somewhere, pay to power it and pay someone to keep it ticking over. Not a small undertaking.
As for licensing, I'm sure that there's some legal gubbins to be sorted out when copying and storing that much copyrighted (copywritten?) material. Virgin being a big telly provider may well have the legals sorted out in the same way they do for providing the 'live' BBC telly stream.
That is truly awesome
I think I can implement that between floors in my building with minimal loss in bandwidth merely by sending larger packets!
Learning from each other's mistakes?
I understand that from a business perspective the exact reasons for the titsup may not be good to disclose. Companies automatically go into face-save mode and make statements and quote statistics proving how rare such things are etc.
The problem I see with that is the lack of information sharing. They use off the shelf products in a configuration probably quite similar to other people. If they were to say "Hey guys, we had X and Y in Z config but when X did A and Y did B then Z went pop!" then we all could learn about nasty gotchas.
Yes, I know the problems with that include, but are not limited to; Trade Secrets or maybe having a stupid setup you don't want to admit to.
Oh, OK. I'm just a dreamer who lives in a fantasy world of people helping each other out.
Just face it...
...Writing like that is why we love El Reg.

Every single one of our clients in the UK
My wife's company and my friend's company. Also some users I know in continental Europe and South Africa.
Not that EVERY problem is necessarily related to the current issue bit I think it's quite widespread.
"Microsoft buys Skype and it all goes tits-up". Truth is it may have nothing to do with Microsoft at all, but it's what we're all thinking, isn't it?
So hang on....
...She wouldn't have laughed seeing someone else doing the same thing?
Anyway, she got up immediately and walked away as if nothing had happened. Why would security have to go and check on her? It's not as if they left her floating face down in the fountain for those 20 minutes. To me she was demonstrably OK, she showed no signs of distress, just mild embarrassment.
Why do people seem to be unable to take responsibility for their own actions?
No one mentioned
David Gibbons yet.
You're kidding me right?
His surname is Borker?
What do you call it when your name reflects what you do?
Not abandoned Java (totally...)
Abandoned writing the Mac implementation. Leaving it up to Oracle to support the platform as it does with Windows et al. (http://www.apple.com/pr/library/2010/11/12openjdk.html)
I say 'not totally' as even though they're not 'killing' Java per se they won't be supporting Java apps in the upcoming Mac App Store. Which some would argue is a death of sorts.
Yes, yes, slightly off topic and boring.
I for one...
...etc, etc, etc...
I love these...
Having seen a good many of them myself.
The CAT-5 monster looks like it might just (if we're very, VERY lucky) evolve into a Flying Spaghetti Monster.

It's back up again.
Just all kinds of Awesome
Genuinely inspirational. All you appear to need is the enthusiasm of a kid and a willingness to just get on and do it.
Just get on and do it. Not listen to people who say stuff is hard.
The photos and footage are spectacular too.
Top hole chaps
I can't WAIT to see the footage.
"Oh! I have slipped the surly bonds of earth..." etc.
A new Icon is in order, methinks.
I've climbed Himalayan Mountains in the Annapurna Circuit
And the odd lump in Europe, Kenya and South Africa. I've hung upside down over a 200m drop for a bet (I was young, dumb and stupid, OK?) and I've jumped out of perfectly serviceable aeroplanes with a sheet in a knapsack.
Yet for some reason watching THIS made me feel a little bit sick.
I hope they get paid well. Kudos to some very hardy people. They must be related to the New York High Steel workers of the 1920s :)
NO NO NO!
CAKE IS NOT A THEORY!
(sorry, was I shouting?)
They don't believe in themselves, so...
I don't believe in creationists.
...Of this kind of thinking.
I've always been amazed of the reaction to 'public beta' software ever since Apple Pubic Beta'd Mac OS X. There's all the bitching and moaning about the fact this bit and that bit don't work.
As stated above, this is why it's called a 'Beta'. It isn't finished.
As for Diaspora, it's in ALPHA fer chrissake, that's one BEFORE Beta! Of COURSE it's going to have huge amounts of fail in it. They haven't finished cooking it yet.

You could settle for:

Where have I heard that lately..?
(Just to throw into the mix that I've not had a problem on any of the 11 phones I've updated this morning.)
Excellent use of a variable there. I shall promptly nick it but credit it, of course.
His Pratchettness once quipped...
Something along the lines of:

Stop using Logic
Are you green blooded with pointy ears?
Didn't think so.
It's people like you who take all the fun out of pederasty, sorry, pedantry.

Last of the Decade?
Has Vulture Central managed to crack the whole 'Going Into The Future" thing and are they reporting from a year hence?
Just the one question...
And I expect the flames to engulf me for this.
When doing the Mac tests did you have the drives formatted as FAT23 or as HFS+(J)? It'd be interesting (to me) from a purely empirical point of view as to whether the drives functioned faster when formatted as one type or another.
How Art Imitates Life.
I've been dealing with a luser this week with over 86,000 eMails in their INBOX (16GB or so). Not their whole account. THEIR INBOX. They're wondering why things were running slowly and their account keeps needing to be rebuilt...
If only I'd thought of the fire extinguisher myself, I could have used it on the poor bloody server to cool it down!
