operating system - Difference between switch & bus architecture? -

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.

Would you ever implement a linked list in Javascript? -

i'm learning data structures formally first time. me, of benefits traditionally described of linked lists (easier memory allocation , faster input , deletion body of list) seem moot in js given way arrays work (like objects numbered keys). can give example of why i'd want use linked list in javascript? as comments note, you'd if need constant time insertion/deletion list. there 2 ways array reasonably implemented allow populating non-contiguous indices: as actual c-like contiguous block of memory large enough contain indices used; unpopulated indices contain reference dummy value wouldn't treated populated entries (and excess capacity beyond max index left garbage, since length says it's not important) as hash table keyed integers (based on c-like array) in either case, cost insert @ end going amortized o(1) , spikes of o(n) work done whenever capacity of underlying c-like array exhausted (or hash load threshold exceeded) , reallocation ne

osx - Is there danger in installing 2 versions of Anaconda for Python on one machine? -

some background: have intel mac osx (running yosemite) , use pycharm community edition main ide. code in python 3.4 however, i'm taking mit ocw courses use python 2. make easier on myself when using mit's skeleton files have downloaded python 2.7 , switch pycharm interpreter depending on project. here's question: i'm wondering if run trouble downloading 2.7 , 3.4 versions of anaconda. if ok, need special import commands depending on version of python i'm coding in? thanks! happy add clarity / more info if isn't enough answer questions. there's no danger, it's not recommended way of achieving this. rather, should use conda , package manager comes anaconda, create environment other version of python. instance, if started anaconda3, conda create -n python27 python=2.7 anaconda would create environment called python27 in ~/anaconda/envs/python27 python 2.7 , packages anaconda. point ~/anaconda/bin/python or ~/anaconda/envs/python27

javascript - Passing Query Parameters Into Component EmberJS -

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!

javascript - Pointing package.json to a specific React commit installs react-tools (not react) -

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.

regex - In PHP, what is the most efficient way to match a string against a list of keywords? -

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.

c# - Can DataGridViewCheckBoxCell accept CheckState.Indeterminate programatically, but not via clicking? -

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];
