i have table, contains logs , has following scheme: user | date | log x x x ... now, want make one query retrieve every (user, date) pair, date latest user. i thinking (pseudo): select ... (table) ordered date, distinct user but i'm not sure if that's gonna work. is correct distinct take first possible dates in query, therefore yielding required result? or order of elements in distinct query undefined? if yes, how should solve problem (this case can't add new table, such users and, example, cache lastest dates there) ? now, want make 1 query retrieve every (user, date) pair, date latest user. select user, max(date) yourtable group user you might want add order user . since both user , date reserved words sql dbms, more run. select "user", max("date") "yourtable" group "user";

we have animated spinner gif use spice submit button after user has submitted form. if validation passes on form, assign background via jquery's css() method, setting background image, positioning , color in one. ie9 not showing background image on submit, though continues seen in other browsers. this technique has worked fine in previous ie browsers, seems have broken in ie9, including in older "browser modes". i'm not sure if bug in ie9, has changed behavior , cannot trust ie7/8 modes behave expected because of this. it seems though maybe ie decides not more repainting after user has submitted form. if case i'm not sure i've got way around it, i'd think isn't case. ran previous problem technique in firefox, discovered firefox halts http requests besides form request itself, means if background image not in cache wouldn't work. because of we've taken preloading spinner on image object in memory. interestingly, if manually call met

my project uses sandcastle , sandcastle file builder generate documentation. we're using customized version of script_manifold.js persists user's language preference across pages (the default version resets language preference each page). currently, script located in sandcastle\presentation\vs2005\scripts folder. is there way override script custom version, without having mess sandcastle installation? is, can have file checked source control along source code, , somehow have file used shfb instead of default sandcastle one? never mind, found answer! in shfb project explorer window, can create folder same name presentation style content wish override. works stock content, such html, css or js files. in situation, needed override script_manifold.js file lives in scripts folder of vs2005 presentation style. so needed create folder called scripts in shfb project, put script_manifold.js in folder. it works perfectly. excellent!

can suggest simpler, more elegant implementation of perl's schwartzian transform in groovy? def unsorted = [7, 3, 109, 22, 55] def sortcriterion = { + 1 } def sorted = unsorted.inject([:],{map, v -> map << [(v):sortcriterion(v)]}).sort{it.value}.collect{k,v->k} assert sorted == [ 3, 7, 22, 55, 109] there must better way keys sorted map, instance. here's take on it: def sorted = unsorted.groupby(sortcriterion).sort().values().flatten()

(i put on here , not tex site, useful reading text files, , not latex!) if you're on unix-y machine (this includes macs), task small should reach sed first: $ sed -ne '/^\\begin{theorem}$/,/^\\end{theorem}$/p' doc.tex if you're on windows, though, don't sed bundled os, , perl rather easier install aiui, here's equivalent: > perl -ne 'print if /^\\begin\{theorem\}$/.../^\\end\{theorem\}$/;' doc.tex you may notice distinct resemblance between the

this question occurred mind , want ask here. the case intentional, write loop runs infinitely. how go unit testing it? i ask because, situation may occur anywhere in code. method delegates several other methods, , want know how ran infinite loop what set of input caused it call method (from method) has caused this i have no code written this. question purely knowledge sake if situation arises in future. please respond. how unit test method runs infinite loop input? you can test opposite: " how unit test method method not run longer xxxx milliseconds input". if test fails may have found candidate infinite loop. nunit 2.5 has timeoutattribute makes test fail if test takes longer given amount of milliseconds.

i have 2 identical tables, 1 current values rows, , 1 new values. trying select rows new values table column in new values table has different value column in old values table. query using looks like: select `new`.`item_id` `new_items` `new` join `items` `old` new.item_id = old.item_id , (new.price != old.price || new.description != old.description || new.description_long != old.description_long || new.image_small != old.image_small || new.image_large != old.image_large || new.image_logo1 != old.image_logo1 ) however, query takes way long execute. mysql have better way or know more efficient query? use: select n.item_id new_items n exists (select null old_items o o.item_id = n.item_id , (o.price <> n.price or o.description <> n.description or o.description_long <> n.description_long

is possible somehow create pow function measure types? pow function in f# takes int parameter, , pow function in math class takes float - dosent allow float<cm> . i first thought that: let rec mypow(x:float<cm>,y:int) = if y = 0 x else mypow(x*x, y - 1) might work out, obvious each time come across else line change return type. any suggestions? ankur correct - cannot (without resorting hacks break units). maybe clearer description of problem type of pow function depend on value of argument , f# doesn't allow this. imagine work if using literals second argument, become tricky if used expressions: pow 3 // assuming = 1.0<cm>, return type float<cm ^ 3> pow n // assuming = 1.0<cm>, return type float<cm ^ n> in second case value n have appear in type! you can use nasty tricks (inspired haskell article ), becomes bit crazy. instead of using numeric literals, you'd use s(s(s(n))) represent number 3 . way,

when sending reference counted objects other threads, better better rule of thumb increment count before launching thread or within thread? in more general sense, should (as function) assume parameters passed me accounted or not? incrementing count within new thread pass object wrong. arbitrary amount of code in "parent" thread may run before new "child" thread gets run @ all, in case function in "parent" might return, other stuff, decrement reference count 0, , free object. new thread touch invalid memory, invoking undefined behavior, , hell break lose. further note such bugs go undetected long time, since it's statistically unusual new thread not run immediately. in fact customers/clients see bug first... :-)

searching php.net autovivification gives no results. @ time of writing, wikipedia claims perl has it. there no definitive results when searching google "php autovivification". this php code runs fine: $test['a'][4][6]['b'] = "hello world"; var_dump($test); array 'a' => array 4 => array 'b' => array ... can provide canonical answer (preferably references) php have feature, , details such version introduced in, quirks, shortcuts etc? yes, php have autovivification (and has had long time), although isn't referenced terminology. php.net states: an existing array can modified explicitly setting values in it. this done assigning values array, specifying key in brackets. key can omitted, resulting in empty pair of brackets ([]). $arr[key] = value; $arr[] = value; // key may integer or string // value may value of type

i work spring framework 3.0.5, hibernate 3.6 , mysql server 5.1. ive got questions regarding transaction management in general. use declarative transaction management spring. great if answer questions yes/no (or correct/incorrect) , maybe, if necessary, give short explanations. nice if several people answer in case there different opinions. thank :-) 1) sentences correct: dbms responsible implementation of transactions , behaviour. 1) b) maybe better say: dbms responsible implementation of transactions , behaviour of database (for example when transaction rolled back). 2) hibernate uses database connection. needs transactions, doesnt configurate any(!) settings regarding transactions , behaviour. 3) but: work transactions, hibernate needs know, transactions start, commited , need rolled back. 4) hibernate need know in case of roll happens? think no, because should defined in dbms. (that means: tables shall locked, database operations shall made undone, , on, correct?
