Re: New Platform: Threadripper or Skylake-X

Your comments have served to inform me that RDIMM is slower through, which I did not know. Never had to deal with RDIMM though, so that explains that. Most consumer motherboards won't even POST with RDIMMs, so unless you deal with enterprise-grade workstation/server stuff you need to actively avoid...

Re: New 2nd monitor: exciting launches ahead?

If not failed capacitors, it's probably failed solder joints due to RoHS compliance (lead-free solder), in an area that is subjected to repeated thermal or mechanical stress.

I use good ol' fashioned leaded solder whenever I do component-level repair. They can pry it out of my cold dead hands. :lol:

Re: What are you listening to RIGHT NOW?

Kicking myself for not checking Sibelius out sooner. I don't think anyone will ever replace Beethoven as my all-time favorite classical composer, but the Sibelius symphonies are very good. Edit: On first listen, some of it reminds me of Dvorak; there's that European folk music influence (though Sibe...

Re: Windows 7 Updates

They're probably just getting caught up on a backlog of security issues they've been aware of. I suppose it's possible they know that disclosure of some new big vulnerability is coming, and they're trying to get ahead of the game.

I wouldn't be too concerned. Just business as usual on the internet.

Sibelius violin concerto in D major

Taking a little detour from my (mostly) metal explorations to dig into some of the corners of the classical repertoire I have not previously explored. Some of Tchaikovsky's lesser-known works are also in the queue.

While it is entirely possible that the drive is toast, it is also possible that the disk is just partitioned in a way which is badly confusing Windows. If this is the case, simply wiping the existing partition table (or doing a "write zeros" to the drive) so that it appears to be "fa...

I'm no expert on game engines but multithreaded code is much harder than many give credit for. Synchronization is hard. Yup, and this is why massively parallel algorithms tend to excel for problems where there is minimal, or very regular and well-defined synchronization between the parallel pieces....

In this case, it sounds like something decided to free up disk space because those folders were (supposedly, but actually not) archived to the Cloud. So the recursive delete was intentional.
