Speaking of fibre capacity Bob, when I was back at college in 1991 I had to sit through and pass a tedious unit called Transmission principles.

We were taught that the original fibre optic cables were multi mode with multiple wave fronts and a definite maximum speed. The next generation were graded (refractive) index with a higher top speed. The current generation are really thin mono mode and their speed limitation is only dependent on how fast you can switch the signalling lazer on and off. There is a lot of the old stuff out there though.

I found the above guide to wood screw sizes. It may help someone ?

The size of machine screws and bolts using the M standard also specifies the thread pitch and spanner/screwdriver size. You can find a list in the Wiki for M screw sizes.

If BT and the others do decide to ditch the switched phone network then the terminating equipment for a SIP service could easily be a line powered smart socket. All the socket programming would be done by the provider at their end and all you would have to do is plug in your existing phone.

More sophisticated services could be provided to those who like to play with their network settings but it would be up to them to provide backup power ?

The real operational difference between a skype call and a sip call is that we keep using phone numbers instead of ip addresses.

PABX manufacturers have been supporting SIP (session initialization protocol) trunks for years.

In in order to use sip trunks you must sign up to a sip trunk provider. The provider may or may not supply you with an internet connection ( you can use your own) but it must provide a sip server and a telephone number for all the trunks you rent (you can transfer your existing number if you like)

When you make a call a setup request using sip inside UDP packets is sent to the sip server. The sip request will contain a destination phone number. If the request is successful then a TCP connection will be established using RTP (real-time transmission protocol) to carry the actual audio. RTP its self does not garuntee QoS but it helps with reassembly of packets and gives a strong hint to QoS mechenisems.

The provider of your sip trunks will have a link into the PSTN using either traditional Q931 digital links or maybe even more sip trunks !

Had a funny tiss tiss tiss noise in one of my Mini’s once. The engine started to run rough too.

Turns out the over flow hose had come off the carb float chamber at some point and now the float valve had got stuck so petrol was dripping straight onto the exhaust manifold. Tiss tiss tiss ?

Actually at least part of it is rubbish. I searched for Linux and all the results were for Linux except for the one above which is Windows ?

2 Ways to Remove Saved Passwords in Firefox

Above is the very most recent info I can find on removing saved passwords in firefox running on Linux.

I don’t have a Linux install to hand at the moment so I cant test it but have a look and tell me if its complete rubbish ?

Bob. I see its a 6 speed manual now. Our posts crossed while I was typing.

Its a pity too because I have an idea for the older 5 speed manual but nothing for the 6 speed ?

The “i” in a circle is usually for information. What does it say if you hover over it or click it ?

If its an auto then 11 mph is about right for a change into 2nd on a 5 speed box.

If its a manual, is it when you change gear ?

MPG was a sore point for me.

My company car was a 2 litre 16V Vauxhall Vectra and Vauxhall said it got 36 MPG on the conbind cycle. The AA said they got 38 MPG in testing so my company used that to set a NATIONAL rate of 22p per mile.

I never did a combined cycle. I spent all day in London traffic with the aircon on and I got 25 MPG.

With the small distances I traveled l  never even got to tack a few private miles on to my expences claim like everyone outside London did !

My guess is you are using Chrome and the black key is related to the password bit in the link above.

The green padlock just means you are using HTTPS and your link is secure.

For those who may not know “save” appends changes to the end of an existing but “save as” writes out a whole new file incorporating the changes. The new file will take up less space than the old one with changes added.

[Wheels-Of-Fire]

An example of duplicates it will find is if you ever use save as instead of save. The old versions will be recovered going back many generations.

Still worth a go if you have no backups ?

[Wheels-Of-Fire]

I really do like Recuva by the same people who bring us Ccleaner.

You may have to do a deep scan to get everything back and if you do then be prepared for a session with a duplicate remover because it will recover stuff you deleted months or years ago ?
