You'll be pleased to hear that my house was built somewhere around 1850, when builders still built from (very tough) natural materials, and were in tune with the local geography.

So, it's not on the flood plain at the bottom of the hill.
It's not in the teeth of the gale at the top of the hill.
It's not facing the prevailing winds from the West.

It did have a good clear view of last year's Beast from the East approaching up the valley - but with the dry air from that direction, the snowdrifts were easily managed. So, bring on your worst!

Kudos to British Telecom:

Hello,
We’re making your broadband faster, for free.
We’ll move you onto a connection that on average, gives customers speeds of 67 Mbps. This is quicker than your current package, which has an average speed of 50Mbps.
Edit - my actual speed is 54.93 Mbps already. I wonder how much they'll overshoot by this time?

Weather forecasts are tricky things. Sometimes "northern and western parts" means Scotland and Wales, sometimes it means here. Actually, I think 'here' has a micro-climate all of its own, which doesn't appear in any forecast.

I'll try to work out which deity is in charge - possibly Rombald the Giant, though I'm not sure if he's been elevated yet.

1) Asteroids@home, with a WU name identical for GPU and CPU, has been that way for years and my complaint will be likely ignored. I'll isolate it to a single machine with the GPU it needs or a separate BOINC directory or VM.
The identical name (by itself) shouldn't be a problem. The CPU and GPU tasks will need different different binary code to run them, and they should be distinguishable by Plan Class (shown in brackets in the 'Application' column in BOINC Manager, Advanced view - probably for the GPU tasks only).

Provided the separate plan class for GPU apps is in place, BOINC should track the estimated run times for the two different processes independently.

[I thought that Einstein was the only GPU-project still failing to do that, because they deliberately opted out of CreditNew, for understandable reasons]

I must find my tuit and get my RPi up and running........
I've got a round one somewhere. I can bring it to the Dutchman's central meet if you want to borrow it.

Is this the first time that a feature request has progressed from idea to implementation within the course of a single SETI maintenance session, during which can't search the message boards?

You might think that the Razorbill's departure might have been scheduled for the convenience of booked passengers.

Or does the Razorbill need high tide, while the passengers need low tide? Six hours in the souvenir shop to match the two up?

Further down, it explains that T.O.M. was actually Hiram Percy Maxim, who Wiki identifies as

He was the son of Sir Hiram Maxim, inventor of the Maxim Machine gun.
which was "an instrument of torture and discipline", if ever there was one.
11) Message boards : BOINC client : Problem building client with VS2017 (Message 90034)
Posted 9 days ago by Richard Haselgrove
Post:
That sounds very plausible. OpenCL is supposed to be a universal, platform independent, programming language. I've seen Windows 10 install an NVidia driver from Microsoft, which had CUDA support but not OpenCL. Later, I let the same machine download an Intel GPU driver from Microsoft, which came with OpenCL. Lo and behold, when I put the NVidia card back in the machine, that had OpenCL support too, using the Intel tools.

There are BOINC users who advocate using 'clean install' and a driver removal utility at every update: I think that's overkill, but worth having available as a standby in case problems like this crop up.

Isn't that the mechanism designed for 'non compute intensive' tasks? (Like the old Quake Catcher application, which would simply sit in the background doing very little, waiting for the earth to move)

... and everyone else uses VS2013.
Including the CI ('continuous integration') automated testing which takes place within minutes after every code change. If you build on VS2013, and you see that the AppVeyor check has passed on the branch you're interested in, you know you can concentrate on the logic and not worry about syntax errors.

There are many projects that force down work and flood the cache, ignoring their resource share.
Projects servers can't actually 'force down work' - the firewall and NAT (Network Address Translation) in your router would prevent that.

Project servers can only communicate with your computer in the form of a reply to a request made by your computer. I'd be interested to see the request/reply pair for an event like this - the <sched_op_debug> event log flag is useful for this:

11/02/2019 08:45:02 | SETI@home | Sending scheduler request: To report completed tasks.
11/02/2019 08:45:02 | SETI@home | Reporting 5 completed tasks
11/02/2019 08:45:02 | SETI@home | Requesting new tasks for NVIDIA GPU
11/02/2019 08:45:02 | SETI@home | [sched_op] NVIDIA GPU work request: 7683.10 seconds; 0.00 devices
11/02/2019 08:45:06 | SETI@home | Scheduler request completed: got 8 new tasks
11/02/2019 08:45:06 | SETI@home | [sched_op] estimated total NVIDIA GPU task duration: 7907 seconds
Note that the amounts requested and received are expressed in seconds - duration requested and runtime estimated. They should match.

I've successfully built with VS2013, but I haven't tried VS2017.

I think you would have to update the whole vs2013 solution file - Microsoft probably has an import wizard which will break the back of that process, but you may still need to tweak some lines manually.

You would also need to assemble a Windows build dependencies tree for VS2017 (that gives you curl, openssl, wxwidgets, and zlib - there may be more). I don't know how much the format changes between versions.

The simplest way these days - now you've inadvertently given away that you're running Windows - is to make, apply, and then unmake and save a trivial change to one of the Event Log Options (Ctrl+Shift+F, from BOINC Manager).

That will create a complete, working, cc_config.xml file with your current settings as defaults. Then, edit that file with a plain text editor like Notepad, and change 0 to 1 in the relevant line. As Jord says, for this particular value a restart of BOINC is necessary: for many of the others 'Read config files' from the Manager is sufficient.

That's a good point. All the modern talk is about the customer switching, but it happens the other way too - and nobody talks about that. I once had a bank account, and my custom was 'bought' twice by new owners without my consent. I started with Girobank, but found myself taken over by first Alliance & Leicester, then later by Santander. Nobody asked my permission - I was just a chattel.

Reply from Shawn Kwang, Einstein Administrator:

We're aware of the problem. And I think we have a fix, but it may not have be deployed yet. Hopefully this will be fixed soon.

I've compared notes with Eric and Jeff in the SETI lab. According to my logs, the upload problems we were suffering yesterday cleared at 02:08 UTC this morning. They saw the same message as "At 6:10pm [PST] on Tuesday the 5th..." - which is the same time, within a couple of minutes.

So it seems that Bruno's woes were indeed related to the Campus IST issue, and were solved by replacing the failed router.
