using ext grid display real-time data. grid refreshed once second. scrolling top on every refresh until overrode scrolltotop function. ext.override(ext.grid.gridview, { scrolltotop: ext.emptyfn }); however, still hangs (prevents scrolling) non-trivial amount of time. how can rid of hang? obviously grid take some non-trivial amount of time render 400 rows of data. can try reduce rendering workload making grid markup light possible (no fancy renderers etc.), best bet may either wait extjs version 4 (which reputedly offers a huge boost grid performance ), or if willing use plugins, have @ ext.ux.livegrid .

will method process each element of array if array being updated within code block of each loop? for example: arr.each |x| if (x != 2) arr.push(x+4) end end will loop still iterate on every element within array, though being lengthened? maybe yes , if talking mri , , question is: " will iterator traverse new elements? ". if talking ruby language, " maybe ". there no specification mri serves reference implementation. but having said that, seems implementation-specific, partly because requiring specific behavior impose constraint on implementations no clear benefit, performance trade-offs. it's quite imperative , it's perhaps not "the ruby way", leans more functional styles . here how think ruby program should write sort of loop. expression return old array unless changes, in case creates new array in functional style there never doubt result be... >> = [1, 2, 3] => [1, 2, 3] >> a.inject(a) ...

i'm trying build vba form runs sql server stored procedure cache data before else. ideally i'd prefer not use excel data connection because can't export new workbook minimum of fuss - it'd nice contain of information in form's file. the main way know connect vba database using code along these lines: dim cnn new adodb.connection dim rst new adodb.recordset cnn.open connectionstring rst.open querytext, cnn, adopendynamic /*whatever you're doing data goes here*/ rst.close cnn.close the problem i'm running caching proc doesn't return dataset (not blank one), , type of connection seems throw tizzy if there no data returned. , i'd prefer not modify proc if don't have to. is there feasible solution, within these constraints? or being whiny , should suck , use excel data connection or something? i think looking adodb.command. try this: dim cnn new adodb.connection dim cmd adodb.command cnn.open connectionstring set cmd = new...

i learned today following java code legal: myblock: { /* ... code ... */ if (doneexecutingthisblock()) break myblock; /* ... more code ... */ } note myblock isn't loop - it's block of code i've delimited curly braces. this seems rather strange feature have. means can use named break break out of if statement or anonymous block, though can't use break statement in these contexts. my question this: is there reason design decision? is, why make can break out of enclosing statements using labeled break s not regular break s? , why allow behavior @ all? given how (comparatively) well-designed java language assume there's reason this, can't think of one. it plausible done simplicity. if labeled break can break loop statements, should clear language designer restriction isn't necessary, semantics work same statements. economics of language spec, , simpler implementation of compilers, or out of habit towards genera...

i've found gorgeous switch i'd implement in ios. artist (@jasonlong) has kindly shared psd of components @ 365psd.com , along crafty little javascript demo. now, here's trouble... custom uislider , uiswitch examples i've found seem rely on track that's stationary movable knob/toggle. in switch below, require knob/track animate behind mask passes through touch events. i've never been of interface coder, cute little bugger awesome leave alone. can point me in right direction? i suggest having background stationary, , fade between them? sliding track not going work well, can still see green/white around edge of knob.

is possible write c++(0x) metafunction determines whether type callable? by callable type mean function type, function pointer type, function reference type (these detected boost::function_types::is_callable_builtin ), lambda types, , class overloaded operator() (and maybe class implicit conversion operator 1 of these, that's not absolutely necessary). edit : metafunction should detect presence of operator() signature, including templated operator() . believe difficult part. edit : here use case: template <typename predicate1, typename predicate2> struct and_predicate { template <typename argt> bool operator()(const argt& arg) { return predicate1(arg) && predicate2(arg); } predicate1 predicate1; predicate2 predicate2; }; template <typename predicate1, typename predicate2> enable_if<ice_and<is_callable<predicate1>::value, is_callable<predicate2>::value>::value, ...

i writing script needs book seats in cinema. user asks 2 seats if there 2 seats available, system offers them client client can either accept them or request 2 seats. when accepts, seats marked "sold" since there can multiple users using system simultaneously, need way "lock" rows offered current client until time passes, or requests seats. currently marking offered seats "locked" client id, , use select return them client (this mysql, target database postgres) update seats set status = "locked", lock_time = now(), lock_id = "lock1" limit 2 select * seats lock_id = "lock1" , lock_time > date_sub(now(), interval 2 minute) there problem that: if there's 1 seat available, still marked "locked" , have release lock right away. i pretty sure there smarter way of doing that. correct way of dealing task that? race condition - think better insert rather update. 2 updates can run @ same t...

in web page: http://web.eecs.utk.edu/~huangj/cs302s04/notes/external-sorting2.html merge resulting runs successively bigger runs, until file sorted. as quoted, how can merge resulting runs together??? don't hava memory. imagine have numbers 1 - 9 9 7 2 6 3 4 8 5 1 and let's suppose 3 fit in memory @ time. so you'd break them chunks of 3 , sort each, storing each result in separate file: 279 346 158 now you'd open each of 3 files streams , read first value each: 2 3 1 output lowest value 1 , , next value stream, have: 2 3 5 output next lowest value 2 , , continue onwards until you've outputted entire sorted list.

i'm total newbie , i'm confused tutorial. know (at least think know) functions getdate , month , getfullyear pre-set functions determined javascript. why preset functions necessary tutorial if new date (2000,0,1) being submitted argument formatdate? getdate clash somehow numbers submitted argument? in function pad, understand "number" checks see whether number less 10 and, if so, adds zero, argument submitted function pad? how numbers check? can please take me through (using plain language) tutorial step step...thank in advance function formatdate(date) { function pad(number) { if (number < 10) return "0" + number; else return number; } return pad(date.getdate()) + "/" + pad(date.getmonth() + 1) + "/" + date.getfullyear(); } print(formatdate(new date(2000, 0, 1))); this function formats , prints date. the pad function add "0" (not add 10 noted) in front of number l...

for small c/c++ projects used write clean target follow: clean: $(rm) *.o *~ for bigger projects, when sources dispatched in subdirectories, src1 , src2 , write clean: $(rm) src1/*.o src1/*~ src2/*.o src2/*~ with more subdirectories, becomes messy… realized use find command this: clean: find . -name "*.o" -exec $(rm) {} \; find . -name "*~" -exec $(rm) {} \; however saw people use find in conjunction xargs instead of using -exec , wonder why since seems work fine… what use , why? i know big projects, or better compatibility, should use cmake or autotools simplicity of makefile small projects. because exec creates 1 sub-process per file being deleted. xargs , on other hand, batches them up. it's difference between: rm src1/a.o rm src1/b.o rm src2/c.o and: rm src1/a.o src1/b.o src2/c.o it's not going matter unless have lot of files it's worth knowing use case. but don't use either of met...
