i want filter elements using angular's filter check on 2 attributes , number of returned elements this have tried: $scope.countpriorityactive = true; $scope.getcountactive = function(strcat) { return filterfilteractive($scope.tasks, {priority: strcat, active: true}).length; }; but it's not working have started editing example: http://plnkr.co/edit/8ybrtd?p=preview what's mistake? you forgot add "active" attribute in elements of array { id: 1, name: 'iron man', fname: 'tony', lname: 'stark', location: 'stark tower', comic: 'marvel' active: true //this need add each element }, also need call "filterfilter", not "filterfilteractive" unless made new filter yourself

i have file in chef recipe , on node configure chef. want if file modify automatically changes in configured node using chef. my approach is, make recipe , put file in template folder , put recipe in runlist of nodes. cron scheduled chef-client on nodes. when files updated , recipe uploaded on server, files on nodes update. other approach more efficiently. is possible without cron. eg. chef server if file modify in recipe. it depends - always. you can use remote_file resource download files remote locations (e.g. via http). way, chef can automatically deploy updated files, if replace on source server. you can use use git or deploy resources deploy files git repository. way, update git repo , chef update node new content. but either way, chef-client changes during chef run. can trigger through cron or run chef service. triggering chef-client run automatically, either kick-off chef-client via ssh (e.g. automated jenkins server) or might give chef's push j...

i'm reading prml , gradient notation seems confusing. in chapter 2, page 116, a column vector: and on appendix e page 707, column vector: however, in chapter 3, during derivation of least-square, page 141, row vector: can clarify these confusing details me? have read posts on web, of them says gradient strictly column vector, says depends on calculation being carried out, says depends on author, , couldn't come conclusive answer the answer stated in question - gradient vector of partial derivatives, treating column/row vector not matter. people use orientation best particular use/derivation, same applies putting data points in data matrix row/column wise, defining linear projections column/row vectors etc. thus, answer it depends on particular use , have check kind of notation author uses. why that? because not matter, , calculations - row notation reduces amount of transpose operations needed, , - column notation helps. that's all.

"1" ≡ (λf.(λx.(fx))) : think of (λf.(λx.(fx))) meaning: given function f , element x , result (fx) : should thought of apply f x or, in more standard mathematical notation, f(x) . "2" ≡ (λf.(λx.(f(fx)))) : think of (λf.(λx.(f(fx)))) meaning: given function f , element x , result (f(fx)) : should thought of apply f x twice or, in more standard mathematical notation, f(f(x)) .

the code below: v1 = document.getelementbyid('double').value; while (v1 < 10) { v1++; = new date().gettime(); while(new date().gettime() < + 1000){} document.getelementbyid('inputarea').value = v1; } inputarea text box has 1 number, want increase number 1 ever second until reaches 10. problem inputarea shows last value 10, supposed ....7, 8, 9 10. you can use setinterval var timerid = setinterval(function(){ v1 = parseint(document.getelementbyid('double').value,10); if(v1 == 10){ clearinterval(timerid) } else{ document.getelementbyid('double').value = (v1+1) } },1000); <input id="double" value="1" />
