Is the order of messages sent by SignalR constant on the client? -

i have simple question regarding signalr, possible signalr messages arrive in out of sync order. i.e if send messages a,b,c server, possible client might messages in order other a,b,c? thank in advance! there isn't guaranteeing equal performance of delivery client assuming independent message calls. need consider handling on client side. of course if running server async have impact well.

determining the sum of top-left to bottom-right diagonal values in a matrix with Ruby? -

i have square matrix of indeterminate row & column length (assume rows , columns equal befits square). i've plotted out example matrix follows: matrix = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ] my goal sum top-left bottom-right of diagonal values. obviously in example, i'll need: diagsum = matrix[0][0]+matrix[1][1]+matrix[2][2] #=> 15 i see pattern it's +1 incremental each row & column argument in matrix, code i've developed matrix of indeterminate length (supplied argument method diagsum preferably need implement sort of row_count method on matrix argument. if arr = [[1,2,3], [4,5,6], [7,8,9]] then: require 'matrix' matrix[*arr].trace #=> 15

javascript - Swap an image without flicker while showing the new one immediately -

tl;dr: there way swap images reliably while showing whichever image being loaded @ time without causing page flicker? i have 2 images , 2 buttons , when hover on 1 button shows 1 image. hovering on other button swaps second image. doing this: $('#button1').mouseover(function() { $('#image').attr('src', 'image1.png'); }); $('#button2').mouseover(function() { $('#image').attr('src', 'image2.png'); }); this works fine when first image has loaded , second hasn't, doesn't show second image until has completed loading. try give user indication of when new image loading (which they're expecting appear immediately), forced add null image before these swaps, this: $('#button1').mouseover(function() { $('#image').attr('src', '#'); $('#image').attr('src', 'image1.png'); }); $('#button2').mouseover(function() { $('#image...

git - GitHub Pull Requests Between Branches -

my organization making transition svn git (hosted on github) , have adopted git-flow branching model. we have been using pull requests merge between branches. use github web interface process merge , close request. pull requests merged --no-ff. merge commit occur in destination branch. so.... merge develop master - happens after merge develop branch both behind (due merge commits not being in master) , ahead (due new work being done in develop). over many iterations, end "develop branch both 23 commits behind , 7 commits ahead of master" - seems ridiculous. should not worry this? should merge manually , not through githuib web interface? if reason develop ever behind because of merge commits, should able routinely schedule sync. git fetch git checkout develop git merge --ff-only master git push if have hotfix branch went in, worst case above fail. you're going merge without --ff-only tag. that's perfectly acceptable , expected (...

c++ - Preprocessor directive for certain address space -

lets wanted define directive take int8_t , store specified memory location 0x0071. how this? i know say #define ddra 0xaa and make ddra = 0xaa, how make typing ddra = 0xbb; will write 0xbb in address location 0x0071? the avr-gcc headers define i/o ports using internal _sfr_io8 macro, e.g. in <avr/iom328p.h> : #define portb _sfr_io8(0x05) this macro defined in <avr/srf_defs.h> as: #define _sfr_io8(io_addr) _mmio_byte((io_addr) + __sfr_offset) which, in turn, resolved _mmio_byte macro in same file: #define _mmio_byte(mem_addr) (*(volatile uint8_t *)(mem_addr)) the definition of __sfr_offset is… little obscure. has 32-byte offset between avr i/o space , start of memory. tl;dr: #define ddra _sfr_io8(0x71) , standard headers part should doing if it's standard i/o port.

c# - Sort List with duplicate keys by custom comparer -

i have list inputcoll of type myvalue many duplicate keys: myvalue1.id=100; myvalue2.id=100; ...etc and have custom comparer compare 2 myvalue elements id : inputcoll.sort(myvaluecomparer); what doing wrong? comparer: public class myvaluecomparerbyid : icomparer<myvalue> { public int compare(myvalue x, myvalue y) { if (x.id == y.id) return 0; else if (x.id > y.id) return -1; else if (x.id < y.id) return 1; return 0; } } unless equality comparer not implemented badly, solution should work. but suggest easier approach, using linq: inputcol = inputcol.orderby(o => o.id).tolist();
