i'm interested in peoples' views on how best store preferences , default settings in cross-platform applications. i work in node.js , perl on *nix , windows i'm interested in bigger picture. in *nix world "dotfiles" (and directories) common system-wide or application default settings residing in 1 path , user-specific settings in home directory. such files , dirs begin dot "." , hidden default directory listings. windows has registry has paths defaults , per-user overrides. certain cross-platform apps own way, firefox uses javascript preference files. should cross-platform app use 1 system across platforms or dotfiles on *nix , registry on windows? favourite programming language have library or module accessing them in standard way? there emerging best practice or roll own? what storing in db? cluster-friendly , has been working great us. in last job used store them in directory server. java has support in form of preferences api

very strange thing happening here in ie7, ie8: index.php versus index-2.php as can see on index.php, button below "registration details" visible. on index-2.php, button not. difference between these 2 pages <a href> . on index.php <a href> existing page (but incorrect page) our-partners.php. on index-2.php, <a href> correct (and existing page) register-now.php. can please explain why happening? i'm going crazy trying understand! despite changing html & css suggested below, it's still not working correctly seemingly because of <a href> ! mtia! well, can see on both pages (ff 3.5). however, advise against putting <a href> around <div> that. might better idea use <a href="..." class="read-more"> , add display: block; style of read-more class. may or may not solve original problem ;)

i asked here while ago matching text inside of 2 wrapped <code>..</code> tags string, , it's been working great until had other html wrapped inside <code> tags. this how i'm doing far: preg_match_all("!<code>([^<]*)</code>!", $string, $return_array); could improve regular exp. solve problem? :) thanks in advanced! this 1 case have agree dreaded regex evil meme. straightforward extraction purposes, regular expressions suitable. if want process malformed , or nested html, it's not option without significant fuss. hence i'd recommend using phpquery or querypath such occasions. it's pretty simple: print qp($html)->find("code")->text();

i'm trying review final , i'm going on example problems given me professor. can explain me concept of how leaky bucket works. here's review problem professor gave me leaky buckets. a leaky bucket @ host network interface. data rate in network 2 mbyte/s , data rate application bucket 2m5 mbyte/s a.) suppose host has 250 mbytes send onto network , sends data in 1 burst. should minimum capacity of bucket (in byte) in order no data lost? b.) suppose capacity of bucket 100m bytes. longest burst time host in order no data lost? leaky bucket symbolizes bucket small hole allowing water (data) come out @ bottom. since top of bucket has greater aperture bottom, can put water in faster goes out (so bucket fills up). basically, represents buffer on network between 2 links different rates. problem a we can compute sending data take 250mbyte / (2,5mbyte / s) = 100 s. during 100 s, bucket have retransmitted (leaked) 100s * 2mbyte/s = 200mbytes so bucket need m

i've got table returns history of value, current one, each date. the oldest date main record. if value changed, new record created, old value, , main record updated new value. if happens again, third record created, contains old value. so if value starts @ 4, changes 2, again changes 1. records go 1 4 2 i'm creating inner join on table follows, gets max date of 3 above records, 2.. actual value need 4. easiest way tell if record historical 1 triageenddatetime null. inner join (select emergencyattendanceid,min(sourcecreatedatetime) max_date factemergencyattendancetriagedetail group emergencyattendanceid) eaid on eaid.emergencyattendanceid = factemergencyattendancetriagedetail.emergencyattendanceid , eaid.max_date = factemergencyattendancetriagedetail.sourcecreatedatetime what need select second record, if exists. along lines of this. select emergencyattendanceid,min(sourcecreatedatetime) m

i need table http://code.google.com/apis/chart/docs/gallery/qr_codes.html#details in program , i'm not sure if associative array way go. given type (numeric/alphanumeric), number of characters , ec (error correction) level, want function return version (first column). first, javascript has "arrays" , "objects". 'associative array' assume mean javascript object, using keys other non-negative integers. you can create javascript object literals using syntax such following: var versions = { "1" : { rowcols : [21,21], charsbyeclevel : { l : { digits:41, alpha:25 }, m : { digits:34, alpha:20 } } }, "2" : { rowcols : [25,25], charsbyeclevel : { l : { digits:77, alpha:47 }, m : { digits:63, alpha:48 } } } }; you access properties so: console.log( versions[1].charsbyeclevel.l.di

when try run dll compiled in visual studio 2010, following message: this assembly built runtime newer loaded runtime , cannot loaded. i'm guessing means recent version of visual studio. there way can build dll earlier version? all assemblies in final solution, dlls or exes, in different solutions or in same one, must target same version of clr. can ensure configuring targeting in 2010 solution. most you're targeting 4.0 in dll's project. crank 3.5 or earlier , see if fixes problem.

i discovered lucene (java library) , starting read on it. i'm interesting in taking works of literature (for example, philo, josephus), , indexing them, doing following types of analysis (similar bible software programs do): 1) find word x within 2 or 3 words of word y 2) find "work* of * hand*" - find "works of hands", "work of hand" etc... 3) find literary patterns (also called "motiffs") such author uses phrase "in day". (i think might trickiest, might have find combinations of 2-7 word phrases count them , rank them, showing top 25 example). might show example josephus use 1 sets of phrases, , philo another. are there open-source libraries recommend? language preferences 1) python, 2) c#, 3) java. ideally no dependencies on proprietary database. thanks, neal lucene best 1 out there in opinion in terms of popularity, community, activity , tooling. suggest @ solr built on top of lucene. open source

my current project involves lexing , parsing script code, , such i'm using fslex , fsyacc. fslex lexbuffers can come in either lexbuffer<char> , lexbuffer<byte> varieties, , i'd have option use both. in order user both, need lexeme function of type ^buf -> string. far, attempts @ specialization have looked like: let inline lexeme (lexbuf: ^buf) : ^buf -> string ^buf : (member lexeme: char array) = new system.string(lexbuf.lexeme) let inline lexeme (lexbuf: ^buf) : ^buf -> string ^buf : (member lexeme: byte array) = system.text.encoding.utf8.getstring(lexbuf.lexeme) i'm getting type error stating function body should of type ^buf -> string , inferred type string . clearly, i'm doing (majorly?) wrong. is i'm attempting possible in f#? if so, can point me proper path? thanks! functions , members marked inline cannot overloaded, original strategy won't work. need write different code both of declarations, ne

i developing gui in qt have show battery status icon. system power status, using windows api. show status anytime , need use thread continuously read , display power status? i thinking of using event handler. not sure how implement. thinking 1 status icon run thread. has better suggestion, please share. using thread might overkill, using timer might more suitable case. qtimer can used update battery status on given interval. create qtimer object , connect it's timeout() signal slot in object, perhaps in battery state widget. in slot read new state , update icon accordingly. start qtimer instance interval of choice in milliseconds. btw. qt mobility api can used read power state on desktop. anyway if porting not issue, might easier use api platform provides.

i using own custom function populate events: $('#calendar').fullcalendar({ events:getcalendardata }); and happen have calendar 1 of tabs using jquery tabs plugin (tabs created $('#tabs').tabs();). the set-up works, except find when load page, calendar make async request (i see in firebug), if switch tab on calendar displayed, blank (interface fine, no events). if move next month , again, show data fine. also, if make calendar on first tab works fine! seems initial request not rendering events, perhaps because tab hidden @ time loaded. if load page, go calendar tab (showing no events), , happen manually call $('#calendar').fullcalendar( 'render' ); load events. i've tried putting render call after call fullcalendar callback, no dice. callback(events); $('#calendar').fullcalendar( 'render' ); it seems 1 option might bind $('#calendar').fullcalendar( 'render' ); show event of tab, that's tad messy

without curve fit toolbox how fit function data in matlab? in particular, how fit function isn't polynomial, e.g., if want fit function y = x^(1/3) + 5 not integer? if know form of function want fit not know parameters, can use fminsearch find parameters fit data. if have data (possibly noisy) want fit y=x^a + b where a and b are unknown (here assume true values a=1/3 , b=5 ) how i'd have quick answer: here generate data (you not have in real life case) >> x = linspace(0,5,10); >> y = x.^(1/3) + 5; >> y_noisy = y + 0.1*rand(size(y)); then define function want minimize respect a , b , minimize fminsearch . in case, minimize integral of square of difference between data , function used fit. below have defined 2 functions, 1 noisy data, , 1 without noise. see in absence of noise recover values of a and b . nb: fminsearch wotks vector of parameters ( v in case). took a=v(1) and b=v(2) . have provide initial guess v (here [1 1] ). &g

how replace string inside file using perl ? perl -pi -e 's/arun/brun/g' * this worked fine me but when tried change class/students/a class1/students1/b throws error how solve problem ..i tried adding slash ( \ ) before every ( / ) didn't perl -pi -e 's/class/students/a/class1/students1/b/g' * you using / regex delimiter. there / in pattern , replacement . need somehow ensure these / should not treated delimiter. you have 2 options: escape / in pattern , replacement as: perl -pi -e 's/class\/students\/a/class1\/students1\/b/g' * or use different delimiter: perl -pi -e 's#class/students/a#class1/students1/b#g' * method 2 preferred keeps regex short , clean .

i have object have many properties lists. avoid having null checks everywhere before call add, count, clear, etc . . . thought better new lists upfront so inside resource object in case, have following code: public resource() { regions = new list<region>(); directs = new list<direct>(); } public virtual ilist<direct> directs { get; set; } public virtual ilist<region> region{ get; set; } i warning in visual studio saying calling virtual methods in constructor is there wrong or risk code above when using nhibernate ?? if wrong, there better way of achieving goal? that's fine. if want cleaner approach, use: public resource() { _regions = new list<region>(); _directs = new list<direct>(); } ilist<direct> _directs; public virtual ilist<direct> directs { { return _directs; } } ilist<region> _regions; public virtual ilist<region> regions { { return _regions; }
