endianness - Little-endian support in Netty 4 -

-

the new & noteworthy docs 4 state support -ness has changed significantly, going on show use of bytebuf.order(). whilst that's useful localised use within channel handlers, whole downstream pipeline use little-endian buffers.

the upstream handler lengthfieldbasedframedecoder takes constructor argument byte order, downstream handler lengthfieldprepender not. appears support configuration-driven replacement of buffer factories has gone netty 4, how should arrive @ complete little-endian downstream pipeline?

i did this, though feels awfully hacky:

https://gist.github.com/thomaslee/7871444

if wire in pipeline after lengthfieldprepender run, rewrite (big endian) length field using little endian byte ordering.

probably more efficient write length in little endian after measuring length of in & dropping lengthfieldprepender entirely rather adding step pipeline code has been lazily copied & can attest working. :)

i love know if there's better solution beyond hand-rolling stuff in 4.x.

plot - Remove Objects from Legend When You Have Also Used Fit, Matlab -

Image
i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
