i'm trying clone repository on https , reason local config says take cafile tries use value global config. local config: [http] sslcainfo = c:/../cacert-client.pem global config: [http] sslcainfo = /bin/curl-ca-bundle.crt when i'm executing clone command see instead of local value trying use global cafile value. how specify http.sslcainfo inline git clone command? c:/your/path/to/cacert-client.pem should work ,supposing ' /../ ' in question stands your/path/to (otherwise c:/../xx points non-existent path). if doesn't work, can try other syntax: git config http.sslcainfo /c/your/path/to/cacert-client.pem you can set git_curl_verbose 1 , see more of git using. getting path right (either git config , or environment variable git_ssl_cainfo ) bettern alternative: git_ssl_no_verify=true or git config --global http.sslverify false .

i've got simple listplot like list2 = table[{x, sqrt[x]}, {x, 0, 100}]; now want color specific points red, every 5th point, tried mycolor[x_] /; mod[x, 5] == 0 = red; mycolor[_] = blue; now listplot[#, plotstyle -> absolutepointsize[3], colorfunction -> mycolor[#[[all, 1]], colorfunctionscaling -> false]] &[list2] doesnt work quite right, points still blue. wrong here? thanks, archi here easy way result you're after :- list2 = table[{x, sqrt[x]}, {x, 0, 100}]; mycolor[x_] := if[mod[x, 5] == 0, red, blue]; mycolors = mycolor /@ list2[[all, 1]]; listplot[list /@ list2, plotstyle -> map[{absolutepointsize[3], #} &, mycolors]] alternatively, colour function, rm -rf's answer on george's link :- list2 = table[{x, sqrt[x]}, {x, 0, 100}]; mycolor = function[{x, y}, if[mod[x, 5] == 0, red, blue]]; listlineplot[list2, plotstyle -> absolutepointsize[3], colorfunction -> mycolor, colorfunctionscaling -> false]

i have 2 approaches count of rows in table in db2. 1 way is select count(*) foo col1 = val1; another way count results (number 1's list) retrived following query method in java code select 1 foo col1 = val1; here "list of number 1's" second query , size of list in java code count. can explain efficient way rows count ? select count faster - because database needs return single number rather potentially long list.

" + "and winning_time = ?"; try { statement = connection.preparestatement(query); statement.setstring(1, race_name); statement.setint(2, race_year); statement.setstring(3, rider_name); statement.setint(4, distance); statement.setobject(5, winning_time); } catch(sqlexception e) { system.out.println(e1.getmessage()); } to check null , since java 7, have objects.requirenonnull(somevariable); or use overloaded method can specify message. method throw exception if argument passed null

i have following function in link-function in directive: var add_todos = function(todos) { html += "<ul>"; (var = 0; < todos.length; i++) { html += '<li> <input type="checkbox">'+ todos[i].title; add_todos(todos[i].children); html += '</li>'; } html += "</ul>"; }; i use element.replacewith(html) . works well, want use ng-if in checkbox. however, if did html += '<li> <input type="checkbox" ng-click="myfunction()">'+ todos[i].title; , wouldn't work, because, html isn't evaluated angular anymore. i know if used template, evaluate ng-click() , don't know how use template while maintaining linking function. i've been thinking having angularjs regard html template, mean evaluate ng-click() . have no idea, however, how this. other, perhaps more efficient means of getting work, welcome too,

so started unit , answered couple questions outta book. answers show proper understanding of exceptions , try-catch blocks? wanted verify before start working try-catch blocks/exceptions :) what classes (and subclasses) examples of unchecked exceptions? answer: ioexceptions, classnotfoundexception, runtimeexception (its subclasses: arithmeticexception, nullpointerexception, indexoutofboundsexception, illegalargumentexception what 2 different ways programmer can deal checked exceptions avoid compil answer: use either try-catch block or declare exception in method header beforehand. describe steps occur when exception not caught in current method answer: if exception not caught in current method, java exits method, passes exception method invoke method, , continues same process find handler. if no handler found in chain of methods being invoked, program terminates , prints error message on console. (ths process of finding ‘handler’ called catching , exception. how ‘chai

i have data file separated 2 lines. each section of data ~50 lines. i'm trying make .gif file. know how plot them individually or in group can't .gif work. my problem similar 1 worked out glen maclachlan in youtube channel, part 5. instead of 1 point, have ~50 data points each data section. solves problem utilizing $index feature, , tried same mine doesn't work. what missing? have plot data separately .png files , group them .gif file? what i've done::: i edited data file. there 2 columns x, , y. now, have them in 2nd , 3rd column, , first column index 0 50. each block of data has similar index. bash script create plot file for ((i=0;i < 50; i++)) echo "plot 'data.txt' u 2:3 w circles index $i"; done >>simulate.plt it plots data points why don't show have tried? the following should work fine: set terminal gif animate delay 100 set output 'foobar.gif' stats 'datafile' nooutput set xrange [-0.

i learning html forms , in particular action attribute has me bit confused. difference between following values , when best use each case? action="" action="?" action="?page" action="?page=main" action="." action="../" action="/" action="#" from w3 form documentation : this [action] attribute specifies form processing agent that is, form, when submitted, sends values wherever action set to. part noted actions submit form same page form displayed on. leave action out together or use <?php echo $_server['php_self']; ?> (if you're on php page) obtain same effect. now, "?page=main" technically go same page well, page value set "main" (might used processing output somehow example). use if need page value, otherwise 1 of blank ones.

say do: with my_connection: o.first_call() where my_connection 's __exit__ method calls rollback and o.first_call in execution calls j.second_call , calls z.third_call . z.third_call inserted record in database, j.second_call inserts record, o.first_call craps out. rollback state before first entered context of my_connection or rollbacked state between o.first_call , j.second_call ? edit: clear, i'm hoping entire thing gets rolled before ever called o.first_call edit2: i'm hoping if there magic in __enter__ , kind of context say, whatever called 1 big transaction. transactions rolled-back last commit call. per database api specification v2.0 : .commit() commit pending transaction database. .rollback() ... causes database roll start of pending transaction. so depends on mean "successfully inserted". if insertion finalized call commit , rollback not remove insertion. however, if there no commit, insert

i have code uses max ogden's websocket-stream library ( https://github.com/maxogden/websocket-stream ), pretty nifty. when this: websocketstream.on('data', function(data){ console.log(data); }); i arraybuffer in client (what want, binary websocket stream). when try implement writable stream (using prototypes or whatever), i'm getting arraybufferview in _write instead of bare arraybuffer :-(. i'm using objectmode:true. the simplest example is: var s = new writable({objectmode:true}); s._write = function(chunk, enc, next){ console.log(chunk); // arraybufferview console.log(enc); // `buffer` next(); } websocketstream.pipe(s); who's newing buffer view, , how can stop them? the workaround take chunk in write , grab .buffer. i'm doing best understand 'implementors' side of newer streams interface, , love things correctly.

my app based on notifications server, using signalr getting entities , adding them using manager.createentity(entitytype, entity, breeze.entitystate.unchanged); the ui based on angular grid bind entities of type, how ever when adding new entity grid isn't being updated, assumption bind cache , not other collection. same issue when removing entity as @pwkad pointed out in comments above, getentities function builds array each time called, returning entities cache match parameters. resulting array won't updated when cache changes. in case, should store array that's returned getentities, add each new entity after that: scope.gridlist = manager.getentities(entitytype); // ... later: scope.gridlist.push(manager.createentity(entitytype, entity, breeze.entitystate.unchanged));

i guess i'm asking difference between order of these 2 operations on arraylist. suppose have following arraylists arraylist<string> list = new arraylist<string>(); arraylist<string> list2 = new arraylist<string>(); list.add("tom"); list.add("jerry"); list.add(1,"harry"); list.set(1,"klaus"); system.out.println(list); output [tom, klaus, jerry] then same thing list2 except switch last 2 statements list2.add("tom"); list2.add("jerry"); list2.set(1,"harry"); list2.add(1,"klaus"); system.out.println(list2); output [tom, klaus, harry] when value set at posiotion why list add an item @ position+1 when attempt add new item @ position as in second list . shouldn't list2 be? [tom, klaus] and shouldn't list have [tom, klaus] its simple add inserts new value @ given index and set replace value @ given index. have @ output after e

running tomcat 7.0 have file in web-inf folder accessible through browser by: http://localhost:8080/wsdarwin_1.0.0/hello.txt how go accessing file , contents in java code ( using relative links, guess ). can access fine using buffered reader , accessing full url such: url requesturl = new url(path_prefix_two+"/request.txt"); bufferedreader testin = new bufferedreader(new inputstreamreader(requesturl.openstream())); but isn't there way access 'locally' ? i'm not using maven for example, accessing file locally permits me this: bufferedreader testin = new bufferedreader(new filereader(new file(path_prefix+"/request.txt"))); path_prefix = "c:/users/username/.../hello.txt"; if change path_prefix "/hello.txt", not access ( file not found error ) not sure if you're looking for, if file deployed in web-inf/classes or in jar in web-inf/lib, can access via thread.currentthread().getcontextclassloader
