Geek Speak / Re: Why different computers/devices may show different times (at seconds precision)?

« on: 16/08/2022 14:29:04 »

I do not normally need time displayed more accurately than plus/minus one second so I use this software that allows me to use various time servers with frequent up dates dsc400r-x64 Duality Software

There seems to have been more success with the sexually promiscuous Bonobos with the unfortunate result that the endemic SIV virus has mutated into HIV.

For the American assassination squad to kill him they had to know where he was and when he would be vunerable.
I understand that million $25.00 was offered for this information and it would be interesting to know if it was paid out.
Even if it included American citizenship and life long protection I cannot believe anyone receiving this money would live very long !

Occasionally NICE will prescribe a course treatment costing up to £200.000.00 if the patient dies before completing the course are the left over pills of any value and can they be put to any use ?

Just Chat! / why does the Grefell tower fire nonsence drag on ?

« on: 14/06/2022 20:05:15 »

it is now five years if the tenants had been prosperous they would have hired good lawyers and the tower would have  been torn down by now and rebuilt with them all compensated.
It seems because they were proles the tower will be left standing as long as the Battersea power station as some sort of memorial with the surving tenants in B&Bs.

Although the difference between the American and the Europeon gallon causes confusion in the MPG figures there is an actual difference in the efficiency of engines because the low octane rating of the fuel means a lower expansion ratio must be used

Technology / Re: How does a toaster know when to pop?

« on: 23/03/2022 12:09:40 »

I have not dismantled my toaster but I believe when you adjust the control for the degree of toasting you vary  the heater current going to a thermally operated release switch that shuts down the toasting  operation.
My toaster has a button for frozen bread which apparently interpose a LED in the  heater current  circuit  delaying the cut off
These must be one of few domestic devices that do not include a computer of ENIAC complexity in their design !
