Counts:-

UTC ..... Out in ..... Awaiting
........ field ...... Validation


19:00 .... 443 ....... 1591
20:50 .... 442 ....... 1571


So, 1 Hour 50 mins elapsed, 1 result came in, but 20 came off the "awaiting validation" count.

Does that mean that there were 20 non-matching results on 1 WU, that the one recieved result cleared?

Hmmm I could understand 3 or even 5, but 20 - Wow!

Edit :- to reformat table data.

It had to happen sooner or later.

Now look at what is being developed

http://www.bbc.co.uk/news/technology-35890486

Imagine one of them passing through a jet turbine while it is landing or taking off

Chicken Gun


For the rest of the aircraft it would probably be no worse than a frozen chicken, but that fuel tank would probably rupture if it was struck by a fan blade, even if the hydrogen did not explode imediately it would burn well when it passed through the rest of the engine.



And those tanks, I would guess Carbon Fibre or similar, may be a little solid for the rest of the engine... unlike the rest of the plastic parts of the drone.

Hmm I wonder about the metal motor parts?... probably too small and light I hope.

Would another species have reached self awareness or domination in the way we have?


I've always wondered this about dinosaurs. They certainly were around long enough to get smart, so why didn't they invent computers?


I thought that their fine manipulation abilities were fairly minimal, or at least in all the ones I've seen skeletons & drawings of.

Unlike Monkeys & Apes - they are fairly dextrous already.

Looking at the extension lead at the bottom left of that pic, it looks like it is in th UK, or a UK wired part of the US.

Not a good idea in homes with free-running pets, I would think.

However, a reasonable heating system...

We saw that film when it was out on general release. I thought it was a very good and deep film, but I agree that the start was a bit slow. However there was, I thought, a lot of background to fill in, including the 'technical' side.

We enjoyed it a lot.
11) Message boards : Cafe SETI : What is this mathematical concept called? (Message 1771063)
Posted 12 Mar 2016 by Profile Graham Middleton
Is there a reason why you cannot use a backup-type tool (there are many - 7-ZIP, WINRAR, I believe Nero etc. etc. ) to create a contiguous conmpressed file that can then span multiple Blu-ray disks?

This would use virtually all the space on every disk other than the last one. Most of these tools can also compress the data input to further optimise storage.

With most of this type of package individual files can still be extracted from the storage set if needed. In addition most allow you to control the amount of redundancy and checking data that is included within the storage set to allow for errors at a later time e.g. for archive storage.

I have used WINRAR and others to do this & still allow the restoration of data after one complete volume of the storage set is unusable.

Several of the tools will allow for data transfer from one platform to another with a different O/S.

If you want any more info, please ask.

I believe that Lode Lane Spanner , Brum Spanner, and Brum screwdriver are all alternative and somewhat derogatory names for a Hammer, usually a large one.

All to do with using the wrong tool for a job.


Brum is a nickname for Birmingham in the UK

The reference to Birmingham Screwdriver is a term referring to the habit of some (usually not so good) carpenters and general builders, of using a hammer to insert screws into wood, in the hope it will hold. Sometimes they might finish with a half-turn of the screw to hold it a bit better. This dates from the days before electric drills, impact drivers etc.

Lode Lane may refer to one of the Land Rover factories in Solihull, though I'm not to sure of this connection.

I think it is a hardware issue, but I just want to be sure before I strip the system down completely.

There's nothing in the event viewer before the system start without a shutdown, just the normal mix of neutral system messages I've seen in other running systems.

Is this a cause or an effect of a system prpblem???

Many thanks for that info, which I wasn't aware of.

I'm still not sure as to why the BSOD, so I'm waiting to see if another comes along, I hope not.

I have rebooted the system since that BSOD reboot earlier on today. The system came up just fine, without those no project URL messages.

I have not detached or reattached since the messages.

The system is running and producing work.

Before the BSON it had been up for about 3 or 4 days withiut issues.

I haven't seen those messages before, and was wondering what they meant. I suspect that they weren't a cause but rather an effect of the BSOD somehow. As far as I can see, they weren't connected with any aborted WUs (at least not that I could see from the history info.

20) Message boards : Cafe SETI : New programming constructs (Message 1768140)
Posted 27 Feb 2016 by Profile Graham Middleton
For the coders out there, let's suggest some new programming language elements...



A few suggestions to start with :-

IF ... THOUGH ... BUT [ALTERNATIVELY ...]

COMEFROM

The UNLESS clause - applies to any other construct e.g. RUN DND UNLESS <managerpresent> )





And for Assembly Programmers (if there are any now) :-


WO Wake Operator
WOI Wake Operator Immediate
EC Electrify Console (See wo & WOI)
DDS Double Dick Speed (use with care in loops)
ICS Increase Clock Speed WARP
WARP Wobble Adjacent Reader and Punch
JRS Jump to Random Subroutine
IOI Ignore Operator Input



Any more thoughts?
