In specifics - the advertisement to sell the ticket is an "invitation to treat". Proferring money to the seller is the "offer" and it's implicit that the offer is on the terms of sale advertised in the invitation to treat (including terms regarding prohibition of cameras/filming) and the seller accepts the offer. The buyer could place an offer whereby they offer to buy the ticket buy allowing filming. The seller can then reject the offer and/or present a counter-offer (e.g. you can film if you pay some fee to allow filming).
The argument from the premier league is around videoing clips off the TV and posting online which is pretty clear copyright infringement.
The 30 days "record" does seem to imply he's doing more than others have done which is rather misleading; it's certainly different from submarines, though.
No, you don't use main memory as a write cache, that would be idiotic. You use it for read cache. Any updates will be written to disk (and memory) before acknowledging to the client.
In any case, it doesn't matter how good your batteries/UPS are if your server or DB software crashes for any reason and you have uncommitted writes in memory, hence why caching writes on a database is a Bad Idea (TM).
Bullshit. Well, either that or our network admins are numpties. We had a switch go down in a data hall. We knew the switch was fubar as we'd lost connectivity to a number of devices at the same time. Networks wouldn't admit a fault. We eventually got moved to new switch ports and lo, everything started working.
The usual approach to any network fault in our place is "replace your NIC". That has, in my memory, fixed maybe two faults.
As for modifying code yourself, that requires a whole set of skills & disciplines many admin teams don't have - I know our team/organisation would struggle with that. There are, of course, 100s of companies who are quite happy downloading source & patching/maintaining it themselves.
Other than that, there's some good advice in there. Version control & release/test cycles are key for any software product.
Now, while I'm not saying that Alcatel is less reliable than Cisco, Cisco generally has the reputation of reliability (warranted or otherwise) and so commands the premium.
The ruling was upheld on September 9, 2005 by a three judge panel of the U.S. Court of Appeals for the Federal Circuit under the doctrine of laches, citing "unreasonably long delays in prosecution"
So, it seems there's a chance that waiting too long can invalidate your claims.
Compare with trademark law where you have to defend it whenever it may be seen to be infringed (see the case where Hoover corp lost the right to have the exclusive rights to the term "hoover"); the same doctrine should apply for patents. Of course, the whole patent system is a mess these days as it was designed in a different age with different industries. Scrapping patents isn't the solution as they provide valuable protection to inventors who put effort into designing something, but they're horribly abused by various parties.
