i going through operating systems textbook got stuck @ switch architecture . please explain , how different bus architecture ? switch architecture , bus architecture 2 aspects of computer networks. the main differences between 2 in bus architecture, paths different components of network shared , response time slow when large number of users there because of single path particular resource(shared memory). in case of switch networks there concurrent paths resource , these paths point point. due reason throughput of switch based architecture more of bus based architecture multiple paths available shared resource , if user not getting off resource, other users not stalled unlike bus architecture stalled due single path.

i throttle file uploads in express 4. mean bytes per second, not number of api calls. i want able simulate slow connection file uploads can test out progress animations. i want limit file upload endpoint , not other endpoints. how can this? ideally, i'd add middleware on specific endpoint , specify transfer speed in bytes/s. if on osx , interested in occasional testing (as opposed standardized test response) i'd take @ apple network link conditioner. here's info . also appears recent versions of chromium , assume chrome have built in network throttling options in dev tools.

i have large number of query parameters route right now, , have component resides in route's template. i want query parameters updated upon change inside component, pass in query parameters via component like: {{comp-name query_param1=query_param1 ... query_param=query_param20 }} i update query params in component with: {{input value=query_param_x}} however, gets tedious , overwhelmingly long passing in 20 parameters. there way make more concise? note: application developing on ember 1.12 , not using ember-data. you can create object contains params, similar this: params = { query_param1, query_param2, ... } pass in params object instead of each individual param: {{comp-name params=params}} also, try think if component needs many parameters. there way break down less complex, smaller components, etc.

on site i'm working on, i've got looking pretty same on main browsers (checking chrome, safari & firefox). all except pesky 1px gap on navigation items, noticeable on active items (when background filled). you can visit site here: http://lumbre.breadadams.com/ this gap i'm talking about i've messed height , line-height , padding , etc. of multiple elements (nav, ul , such), nothing seems trick. however if increase font-size 1.2em 1.3em fits, doesn't on chrome. increasing font 0.1 @ time makes alternate between fitting on chrome , firefox basically. #navigation-container #main-nav ul > li.menu-item-has-children > a::after { content: ""; font-family: fontawesome; margin-left: 4px; position: absolute; } here answer amigo! just add position: absolute; it's :after (the small icon) needs position absolute. it's causing bit of upper space, when give position absolute, friend!

i making game , board 2d array, have procedure print maze , each time prints it should show 'x' player standing. problem keeps 'x' player standing: -1 x -1 -1 -1 2 3 -1 -1 -1 4 5 -1 6 7 -1 9 8 -1 b -1 -1 -1 c d -1 -1 -1 e f -1 1 -1 h g 2 x -1 -1 -1 x 3 -1 -1 -1 4 5 -1 6 7 -1 9 8 -1 b -1 -1 -1 c d -1 -1 -1 e f -1 1 -1 h g there 2 'x's when there should 1 don't know why. def printmaze(maze, x, y): oldroom = maze[y][x] u = x - 1 v = y - 1 maze[v][u] = oldroom maze[y][x] = 'x' in range(9): z in range(4): print str(maze[i][z]).rjust(2), print '' if x , y coordinates of player, first thing set oldroom equal player is. isn't x currently? instead of shuffling around values in maze array, why not check if current location you're printing player is, , print x instead? def printmaze(maze, x, y): in range(9): z in range(4): ...

when add line package.json: "react": "git://github.com/facebook/react.git#08e4420019f74b7c93e64f59c443970359102530" ...and run npm install , find node_modules/react-tools installed when expect see node_modules/react . what doing wrong here? the code @ git://github.com/facebook/react.git not same code gets installed when npm install react . instead, code contains series of build steps used build npm package. far know, there not way use specific sha of react repo npm package; need clone repo, build project, , copy somewhere can require it.

i have list of keywords, , need check whether of these occurs in string. e.g.: /* keywords */ rock paper scissors /* strings */ "this town rocks!" /* match */ "paper patient" /* match */ "hello, world!" /* no match */ i put keywords in array, loop through , preg_match() or substr() on each iteration, seems bit cpu-expensive. i've mucked aroud regexps bit, without success. what efficient way (in terms of lean code , low cpu loads) this? note comparison must case-insensitive. a regex alternatives ensure string scanned once, rather n times n keywords. pcre library optimized. preg_match('/rock|paper|scissors/i', $string); it gets faster if keywords have common prefixes , take advantage of (essentially building trie , inlining it): preg_match('/rock|paper|sci(?:ssors|ence)/i', $string); and there's preg_grep($regex, $array_of_strings); that match against array of strings , return ones match. ...

i have followowing datagridviewcheckboxcell part of datagridview : datagridviewcheckboxcell cell = new datagridviewcheckboxcell(true) {value = checkstate.unchecked}; grdrow.cells.add(cell); grdrow.tag = key; grdfilter.rows.add(grdrow); later on, update state based on whether other check boxes checked. var numchecked = cells.count(c => c.value.equals(true)); cbcell.value = (numchecked == cells.count) ? checkstate.checked : (numchecked == 0 ? checkstate.unchecked : checkstate.indeterminate); this works great. however, if user clicks checkbox, cycles between checked, unchecked, , indeterminate. want cycle between checked , unchecked . if set tristate false on cell, no longer allows me set value checkstate.indeterminate . is there way behavior want? update: i've tried trapping cellvaluechanged event so: void datagridview_cellvaluechanged(object sender, datagridviewcelleventargs e) { var changedcell = grdfilter.rows[e.rowindex].cells[e.columnindex]; ...

i searching on internet , didnt find solution. lets want use 1 paramerer in pdo multiple times. select * `users` inner join `user_names` on `users`.`id`=`user_names`.`id` `user_names`.`name` concat('%', ? ,'%') or `users`.`name` concat('%', ? ,'%') how can avoid use ? 2 times ? looking this: select ? `search_name`, * `users` inner join `user_names` on `users`.`id`=`user_names`.`id` `user_names`.`name` concat('%', `search_name` ,'%') or `users`.`name` concat('%', `search_name` ,'%') thank you you can join subselect contains parameter value or (like below) complete search string. select * `users` inner join `user_names` on `users`.`id`=`user_names`.`id` cross join (select concat('%', x.name, '%') searchstring) x `user_names`.`name` x.searchstring or `users`.`name` x.searchstring
