Single vs dual rank memory
In general dual (or even quad) rank memories offer higher performance in server application:

http://hpc.fs.uni-lj.si/sites/default/files/Memory%20Intel%20Xeon5500.pdf
It's much harder to find any information of memory performance in desktop system. Internet boards present various opinion on single vs dual rank subject, but not supported by any test results. Only info I've found comes from computerbase.de:
http://www.computerbase.de/2014-01/amd-kaveri-arbeitsspeicher/2/
In short: rank number did not make any difference in CPU performance on both Haswell and Kaveri platforms while was significant in GPU tests, especially for AMD where pair of dual rank memories offered 7% better performance than pair of single rank memories on A10-7850K system.

WIWA HD95 - problemy z pamięcią FLASH
W przypadku tego egzemplarza ponowna próba ratowania przez wgrywanie oprogramowania kończyła się niepowodzeniem (błąd upgrade przy ok. 44%).
Serial FLASH: W25Q32FVSIG:
![]() |
| MXL5007T - tuner |
Jakkolwiek podejrzanie porada z wątku http://www.elektroda.pl/rtvforum/viewtopic.php?p=12906996#12906996 by nie wyglądała - pomogła w przypadku tego dekodera - po podgrzaniu pamięci FLASH W25Q32FVSIG dekoder uruchomił się a ponowne wgranie firmware powiodło się. Skuteczność metody w dłuższym okresie czasu nie jest mi na razie znana.
Update 2018.12. Problem z pamięcią FLASH powracał, ale kilkukrotnie powtarzana powyższa procedura przedłużyła żywot dekodera o kilka lat. Aktualnie dekoder czeka na wymianę pamięci - tani chip zamówiony został z Chin.

Google Search spam rant
Whatever Google is doing to fight web search spam does not seem too effective.
Here are search results for "ex-03 usb phone" query:
Custom uninstallers for very niche application (and I'm not even searching for application)? Shit me not. Four out of ten top search result here are domains with algorithmically generated content distributing highly suspicious "uninstallers".
It gets worse: in my personalized (that is when I'm logged in) search results another two similar domains appear in first page thus giving more spam than real content. For comparison: none of these domains appear in top bing, yahoo or yandex search results.
Google search has spam reporting (https://www.google.com/webmasters/tools/spamreportform?hl=en) although my reports here are either ignored or sitting in queue for quite a long time (almost two weeks at the moment).
