Re: [go-nuts] Writing a non-blocking thread-safe buffer

Thanks for all your responses, folks. I'm curious about swapping to a single channel and will try that. On Friday, April 7, 2017 at 4:37:10 PM UTC-6, John Souvestre wrote: > > A few ideas… > > > > Instead of using two channels, use just one. Let the writer(s) use a > “select” to do the write,

[go-nuts] why RES(in top command) change back to high level after GC release the memory to system?

Go programs can only inform the operating system that a page in memory is unused, no API exists to demand that the operating system take it back (save unmapping the memory). Operating systems frequently ignore the advice go programs give to it using the madvise(2) syscall, especially when they a

[go-nuts] why RES(in top command) change back to high level after GC release the memory to system?

Hi, I just wrote a thrift rpc service and run performance testing on the programe. After stoping the test clients (2000 clients), RES (in top command) will reduce to 84M, while 240M when 2000 clients running. But after a few minutes, RES grows back to 240M, and the inuse memory still low in pp

Re: [go-nuts] Can the bit representation of a float64 silently change?

It is not crazy in any way to use the special NaN payload--it was designed just for you. Dr. Kahan and others provided the broad set of NaNs in '754 for just this purpose, for example, to encode missing data values and N/A data values separately for statistical processing, or to allow great freedom

[go-nuts] Can the bit representation of a float64 silently change?

Hi, I'm working on a feature for the Prometheus monitoring system that requires adding special entries in our database. Our values are float64, and I plan on taking advantage of the fact that there's 2^52-1 valid bit representations for NaN. So I'll choose one of those representations for an act
