search for: expessed

I have the following problem. I have an automatically generated named list with "stringified" names: a <- list("A"=..., "B"=..., "C"=..., ) then I want to refer to the elements of the list, stored as an vector of names: nn <- c("A", "B", "C"), so that I could get list elements like a$nn[1], a$nn[2], etc. Obviously it

Grover's search algorithm gives a cryptographically-relevant quantum computer a quadratic speedup. This effectively halves the strength, as expessed in bits, of symmetric ciphers and (I think) hash algorithms. I.e. AES-256 would be "as strong" as AES-128, and AES-128 would be reduced to 64-bit equivalent strength. The latter sounds pretty scary but AIUI the attacker would need to perform close to 2^64 quantum computations to break AE...

Have people given thought to the private key encryption methods in light of potential quantum attacks? While the recent paper about breaking 50bit RSA doesn't pose a threat I've been thinking about future harvest now, decrypt later attacks against CC20 and AES. Are there post quantum ciphers that can effectively replace these available or in development? Is the threat still too far off to

Hello everyone, I'm trying to write a function that will step through a vector of strings and evaluate the contribution to the R-squared of each in turn. I suspect this is related to the anova(model) call but not quite sure how and anova() is order dependent so I have to step through orders anyhow. The issue is that I pass a vector of strings to the function and want to use it as:

Two different issues, but maybe they are related? 1) Attempt to install Compuserve under wine, I initially see three fixme messages: fixme:win:SetWindowTextA cannot set text "Unpacking Compuserve..." of other process qindow (nil) fixme:int21:DOS3Call get interrupt vector - move to winedos... fixme:int21:DOS3Call get interrupt vector - move to winedos... Then an install box is

On packaging systems (for me Fedora),
