i using mvc , jquery pull in function server (as partial view generate on fly , append body of html) , execute it. works fine, can view in fiddler, debugging terrible. pull in method using like: $("#makegrid").click(function (e) { $.get('/gridder/basicgrid', callbackfn); function callbackfn(data) { //append markup dom $('body').append(data); // call js function partialview here generategrid(); } }); whether best practice or not i'm not sure, if 'view source' after ajax command, code isn't visible, , using debugger; command doesn't seem work. eg: function generategrid() { alert("start"); debugger; alert("end"); } creates 2 alerts doesn't bring debugger though firebug active. discussion raises similar issue. worked around using debugger twice (this bug meant gone now) or opening firebug in ...

we using datamapper in sinatra application , use case insensitive works on both sqlite (locally in development) , postgresql (on heroku in production). we have statements treeitem.all(:name.like =>"%#{term}%",:unique => true,:limit => 20) if term is "berl" suggestion "berlin" both sqlite , postgresql backends. if term is "berl" result sqlite , not postgresql. i guess has fact both dm-postgres-adapter , dm-sqlite-adapter outputting like in resulting sql query. since postgresql has case sensitive like (for unwanted) behavior. is there way case insensitive in datamapper without resorting use raw sql query adapter or patching adapter use ilike instead of like ? i of course use in between, such as: treeitem.all(:conditions => ["name ?","%#{term}%"],:unique => true,:limit => 20) but tied use of postgresql within our own code , not configuration adapter. by writing own data object adap...

for example: string 1: aggcct || | | string 2: agccat these 2 strings identical @ 4 positions, function want return 4. is there clever (i.e., fast) method doing this, other obvious method of iterating through both strings @ same time? thanks! uri i don't think "clever" trick beats obvious approach, if it's executed: sum(c1 == c2 c1, c2 in itertools.izip(s1, s2)) or, if use of booleans arithmetic irks you, sum(1 c1, c2 in itertools.izip(s1, s2) if c1 == c2)

hey all. i'm trying optimize linq entities call statically caching , reusing compiled query. query checks same thing variable number of filter arguments, , way compile query arguments explicitly use number of arguments (rather contains()-type logic, in sql can't parameterized). this works great , gives me major performance boost. problem code ugly. repeat same chunk of code number of times each of possible parameters. i.e: expression<func<entities, string, string, string, string, iqueryable<instrument>>> query = (context, searchterm0, searchterm1, searchterm2, searchterm3) => context.instruments .where( (searchterm0 == null || instr.fullname.indexof(searchterm0) > -1 || instr.shortname.indexof(searchterm0) > -1 || instr.strategies.orderby(st => st.level).select(st => st.name).tak...

recently had question regarding data types. since then, i've been trying use namedtuples (with more or less success). my problem currently: - how import lines file new tuples, - how import values separated space/tab(/whatever) given part of tuple? like: monday 8:00 10:00 etr_28135 lh1n1522 computer science 1 tuesday 12:00 14:00 etr_28134 lh1n1544 geography ea 1 first line should go tuple[0]. first data: tuple[0].day; second: tuple[0].start; ..and on. , when new line starts (that's 2 tab (\t), start new tuple, tuple[1]). i use separate data: with open(filename) f: line in f: rawdata = line.strip().split('\t') and rest of logic still missing (the filling of tuples).

we have class manages many queues store data. want user notified when new data added each of these queues. i'd use observer pattern using delegate , events. single event , source, we'd do: public delegate void newdataaddeddelegate(); public event newdataaddeddelegate newdataadded; and observer: qmanager.newdataadded += new qmanager.newdataaddeddelegate(getnewdatafunc); but in case, have, say, 10 queues, each of can receive data arbitrarily. we'd observer functions subscribe individual queue. thought do: public delegate void newdataaddeddelegate(); public event newdataaddeddelegate [] newdataadded; // can't and in constructor of qmanager: newdataadded = new newdataaddeddelegate[numberofqueues]; and in observer: qmanager.newdataadded[0] += new qmanager.newdataaddeddelegate(getnewdatafunc0); qmanager.newdataadded[1] += new qmanager.newdataaddeddelegate(getnewdatafunc1); but no go, since event expected delegate type, not array of delegates type. a...

it's easy make link in rails make post request. link_to 'click me', some_path, :method => :post . works great... unless need pass additional parameters in. because there's no way make actual post request link, rails fakes request, means if try pass additional parameters some_path , builds query string. when mouseover link looks this: /some_path?foo=var&foo=bar[foo][bar] normally wouldn't bad, except gets ugly if you've got controller expecting nested params. so question is, bother else, or me? the workaround can think of change href # , add hidden form nearby, , add click handler link serializes form , submits when link clicked. makes link degrade ungracefully , awful lot of work amounts aesthetic gripe. i'm pretty obsessive urls. there easier way? or being crazy , should deal params in query string? the web ugly place, , 1 of things that's annoying can't make link post without creating form or doing wild javascript handle...

i have wcf webservice (not under control) implements functionality need access via isoneway=true + callback interface, 1 of methods of notifies of processing completion. has been written way designed access gui. however need access same method console application use in batch. crude method of achieving set flag false , after calling wcf method implement while loop brief thread.sleep() call in it. works seems poor way of achieving end result. i'd know proper way of doing is. note: service out of control , reference has been added through ide although can knockup code implementation etc. use manualresetevent waiting completion. call one-way async method on service , wait on manualresetevent object. in callback call set() method let main thread continue execution after waitone() call so: var waithandle = new manualresetevent(); yourwcfobject.calltheonewaymethod(); waithandle.waitone(); void callbackmethodraisedbywcfservice() { waithandle.set(); }

i've data triplets want write in sort of basic owl ontology. i've triplets like: delhi part of india or india asian country note i've relations "is-a", "part-of", or "related-to". what's simplest way build ontology? working example or reference example website great help! there lot of different things mixed in question, suggest take bit of time (away keyboard!) think through you're trying achieve here. firstly, geographic ontologies can quite complex, , lot of work has been done in area. obvious starting point geonames ontology , gives names geographic features, including cities dehli , countries india. @ least should re-use names places in application, maximise chances data can joined other available linked-data sources. however, don't want whole of geonames in application (i'm guessing), need clear why need ontology @ all. way approach outside of application: rather worry kind of jena model use, star...

i want implement encrypted communication between 2 java servers, both under control. there 3 architectures have in mind , want input on pros , cons of them. architecture 1: whenever invoke remote method, not pass parameters plain text serialized ciphertext-object. use esapi-library this, actual implementation not matter. what's important ciphertext-object contains arbitrary data encrypted symmetric key including mac authentication. symmetric key available pre-shared secret on both servers. architecture 2: don't care encryption on application level delegate transport layer. vpn-tunnel or sort of server-to-server encryption supported. don't have information available on modern application server @ moment. input on welcome well. architecture 3: using javax.rmi.ssl use rmi on ssl. it feels architecture 1 complicated , pain implement. architecture 2 leaves encryption application server. application developer have no control on configuration these features. that...

i'm trying optimize code, , got problem don't quite understand. on every page of web app, there list of notifications facebook's new ticker. so, on every request, run code in beggining: notification_query = db.query(ticker, keys_only=true)\ .filter('friends =',self.current_user.key().name()) self._notifications_future = notification_query.run() then, find spot, call middle function is: notification_keys = [future.parent() future in self._notifications_future] self._notifications = db.get_async(notification_keys) finally fetch them @ end: context.update({'notifications': self._notifications.get_result() }) every thing works great except this: if call middle function in end of request's function, this: dumb spot and if call in think optimized spot, this: smart spot as can see api usage doubled making "optimization". going on here? call number 2, first snippet in both cases. call number 12 in dumb spot second snipp...

edit 2: confirmed performance problems due static function call stringextensions class. once removed, indexof method indeed fastest way of accomplishing this. what fastest, case insensitive, way see if string contains string in c#? see accepted solution post here @ case insensitive 'contains(string)' have done preliminary benchmarking , seems using method results in orders of magnitude slower calls on larger strings (> 100 characters) whenever test string cannot found. here methods know of: indexof: public static bool contains(this string source, string tocheck, stringcomparison comp) { if (string.isnullorempty(tocheck) || string.isnullorempty(source)) return false; return source.indexof(tocheck, comp) >= 0; } toupper: source.toupper().contains(tocheck.toupper()); regex: bool contains = regex.match("string search", "string", regexoptions.ignorecase).success; so question is, fastest way on average , why so? ...
