i'm writing geo app , works nicely, i'm considering how it'll work on devices don't have gps or 3g, , wifi may off or not provide location info. is best bet request location update (or use last known) , assume there way location (whether gps or network) or framework include way see what's available, , avoid geo-lookup delay? i figure on device no gps app should provide ui user specify location, , remember in sharedprefs don't have keep re-entering (i'm thinking devices google tv, , tablets). i'd appreciate suggestions on how handle process of acquiring location in context of various devices have different levels of geo-awareness, , how handle that. you can invoke locationmanager.getallproviders() retrieve location providers, or invoke locationmanager.getproviders(true) retrieve active location providers. boolean hasactivelocationprovider = false; locationmanager locationmanager = context.getsystemservice(context.location_service);

when user logs facebook using popup displayed fb.login() call, js sdk plants domain cookie containing oauth access_token in plain text. then, cookie being sent server every subsequent request - , it's pretty obvious not every request uses https . isn't security problem? if so, how solve it? an attacker, able sniff network traffic (e. g. wireless lan), can read cookie. , pretend person created for. this not issue because same attack works on facebook pages itself: username/password - authentication done via https. following pages use unencrypted http, contain cookie. there easy-to-use firefox extension allows steeling of cookies, if able sniff network traffic: http://codebutler.com/firesheep ps: stackoverflow.com vulnerable, too.

i wanting use core plot before work on implementing it, wondering how performs large number of data points. of data want display on line graph has around 5000 data points. can core plot show of data on screen without having scroll see more data? load many points quickly? core plot cache larger graphs this? any comments great. can core plot show of data on screen without having scroll see more data? sure, scale of plot space , axes independent of number of data points. will load many points quickly? it depends on format you're starting (core plot supports several ways of getting data), device you're using, , how define "fairly quickly". gut feeling loading data won't bottleneck no matter format use--drawing 5000 points will. you'll have try see if meet needs. does core plot cache larger graphs this? it caches data in efficient format , there methods add , remove data points without reloading everything. not cache bitmap explicitly.

i getting below error when try set hash value parent url iframe contains domain url: unsafe javascript attempt access frame url "url1" frame url "url2". domains, protocols , ports must match. how can fix problem? from child document of different origin not allowed access top window's location.hash property, allowed set location property itself. this means given top windows location http://example.com/page/ , instead of doing parent.location.hash = "#foobar"; you need know parents location , do parent.location = "http://example.com/page/#foobar"; since resource not navigated work expected, changing hash part of url. if using cross-domain communication, recommend using easyxdm instead.

how garbage collection work in javascript? similar .net garbage collection? , because implementation of garbage collection in vbscript bad people avoided , established preference javascript standard client-side language? how garbage collection work? the short answer is: when block of memory (an object, say) no longer reachable, eligible reclaimed. when, how, or whether reclaimed entirely implementation, , different implementations differently. @ language level, it's automatic. for example: function foo() { var bar; bar = new reallymassiveobject(); bar.somecall(); } when foo returns, object bar points automatically available garbage collection because there nothing left has reference it. contrast with: function foo() { var bar; bar = new reallymassiveobject(); bar.somecall(); return bar; } // elsewhere var b = foo(); ...now reference object survives call, , persists until/unless caller assigns else b or b goes out of s

if (rarely) put flash onto website develop use this: $('#hello').flash({ src: 'hello.swf', width: 320, height: 240 }); yet code flash gives horrible messy bit of code. why 5 lines of code = flash's default html embedding code. right in thinking theres no disadvantage use jquery version? you mean why simpler use jquery flash plugin adobe-provided code? because wraps complexity away you. same stuff still happening in scripts have included, don't see it. if you're including jquery , flash plugin embed flash on page you're downloading more script adobe's default or not-jquery-based 1 swfobject . if you're using jquery on site won't make difference.

i'm trying figure out how automatically add files of extension (for example *.tex) commit dialogue (the checkbox should checked! don't want search new files every single time) i tried adding *.tex auto-commit list (=comma separated list) doesn't anything. mercurial has called hooks stuff automatically on events. see hgrc documentation , mercurial wiki page on hooks . your task can done pre-commit hook, defined in repository's hgrc file: [hooks] pre-commit = hg add -i "*.tex" before commit, hook automatically adds not yet tracked tex files in root of repository's current working directory. adjust value of -i option or add more -i options specify more complex patterns of files add automatically. note: don't use tortoisehg, cannot if hook causes checkboxes pre-selected. anyway, should work if commit tortoisehg.

in sql server 2005 database have column rma_number datatype char(10) in table rma . the value increasing number format rma0002511 . fastest way highest number increment on inserting? my first approach was: select top (1) rma_number rma (rma_generated = 1) order creation_date desc but error-prone because somehow possible higher rma_number has earlier creation date. workaround, sorting primary key works: select top (1) rma_number rma (rma_generated = 1) order idrma desc but maybe possible source of error. logically best way order rma_number desc . but because not sure if gives correct result , thought sorting char column slow if number of records increase, chose order date column. so, is idea order char(10)-column (performance , accuracy)? would better select max( rma_number ) rma highest number(perf. , accuracy) should stick on using primary key order if first 2 points wrong or should use int column , format number in applic

in of classic descriptions of mvc, model notifies views via observer pattern. seems me doesn't happen asp.net mvc, , 1 of fundamental relationships between model, view, , controller missing. is case? if so, why? views in asp.net mvc stateless. exist short time , sent down client. the process goes this: request comes in controller. controller retrieves model , instantiates view (passing model). the view rendered, markup returned client, , disposed of. therefore, since view no longer exists after sent client...there's nothing notify model changes.

if have compare 2 cursors , retrun unique vals how do that example cursor c_stock_option select empid, name, ssn, isenrolled employee isenrolled=1 cursor c_espp_option select empid, name, ssn, isenrolled employee isenrolled=2 now want reject recs in second cursors in cursor 1 select, how do that ummm.....by definition, of rows isenrolled=2 not overlap rows isenrolled=1. think you're asking more general question how exclude rows 1 result set in another. if case, take few different approaches: 1) cursor c_stock_option select empid, name, ssn, isenrolled employee isenrolled=1 minus select empid, name, ssn, isenrolled employee isenrolled=2 2) cursor c_stock_option select empid, name, ssn, isenrolled employee isenrolled=1 , empid not in ( select empid, name, ssn, isenrolled employee isenrolled=2) 3) cursor c_stock_option select empid, name, ssn, isenrolled employee e isenrolled=1 , not exists( select 1 e

is there way in silverlight 4 dictate elements within stackpanel must have margin, instead of specifying margin="10,0" on each one? i'm afraid it's not possible declaratively in xaml stackpanel directly. it's conceptual philosophy in silverlight/wpf panel should not modify properties of children. implement own panel anyway, or use itemscontrol that: <itemscontrol> <itemscontrol.itemtemplate> <datatemplate> <contentpresenter margin="10,0" content="{binding content}" /> </datatemplate> </itemscontrol.itemtemplate> [...] </itemscontrol> an itemscontrol uses stackpanel default, can use itemspanel property define panel itemspaneltemplate if wish so.

i using standard lru queue defined zeromq guide figure 41 , , wondering how add in protection don't send messages end points have disappeared (server crash, oom killer, along lines). from documentation read xrep drop message if going non-existant end-point, , there no way notified that. there way such notification? should send out "ping" first , if don't response "worker" dead meat me? how know same client sent ping getting message from? or use case not 1 zeromq? want make sure message has been received, don't want being dropped on floor without knowledge... pinging worker know if alive cause race condition: worker might answer ping before dies. however, if assume worker not die during request processing (you can little in case), can reverse flow of communication between workers , central queue. let worker fetch request queue (using req / rep connection) , have send answer along original envelope when processing done (using same sock

i cannot understand wrong. mistake:"inconsistent accessibility: return type 'library.servicereference1.author[]' less accessible method 'library.funcs.getauthorslist()'" //class in dll [datacontract] public class author { [datamember] private string fn, n, p; [operationcontract] public string getfamilyname() { return fn; } [operationcontract] public string name() { return n; } [operationcontract] public string patronymic() { return p; } public author(string familyname, string name, string patronymic) { fn = familyname; n = name; p = patronymic; } } //in service public author[] getauthorslist() { return db.singleton.getauthorslist().toarray(); } why have [operationcontract] attributes in datacontract class, believe not valid outside of servicecontract decorated class? if define read properties instead of method

i have 10 cells/rows in uitableview , have set 4 of these cells have text so: if (indexpath.row == 0) { cell.textlabel.text = @"before school"; } im doing of inside: - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { i struggling add uitextfield specific rows. how can achieve this? have managed add uitextfield either or none of them using: [cell addsubview:textfield]; hope can help. you should use if else statements. example: if([indexpath row] == 0){ [cell setaccessoryview:textfield]; }else if([indexpath row] == 1){ [cell setaccessoryview:textfield]; }

in sql stored proc i'm inserting row , hoping return identity int new row, in c# code. alter procedure the_proc @val_2 varchar(10), @val_3 varchar(10) begin set nocount on insert the_table (field_2, field_3) output inserted.field_1 values (@val_2, @val_3) end in c# i'm using linq fuzzy on how retrieve output value. tried including output parameter in sql proc declaration, couldn't working either (exceptions complaining not being supplied in call). closest i've gotten in walking db.designer.cs code, iexecuteresult result returnvalue contains 0 (not correct) inspecting contained results view ( result.returnvalue results view ) have outputed value. key = (int)(db.theproc(val2,val3).returnvalue); key coming 0. want identity int value insert. output inserted.* is same thing doing select. isn't going show output parameter rather come result set. btw, returnvalue should 0 seeing in case. you'll need change linq statement capture resul

i have asp.net datepicker control (no source available ) produces image element, when clicked shows calendar. want disable or enable on demand image through javascript. when added 'disabled' attribute img element, script in page goes in busy state , page never finishes rendering. guess disabled attribute causing conflict in way. my next attempt disable custom click event asp.net control adds unoptrusively. how disable click event? how re-enable img works normal. using jquery 1.4. var $img = $('img#yourid'), handler = $img.get(0).onclick; // previous click handler // unbind $img.unbind('click').click(function(){ alert('new click'); }); // rebind $img.unbind('click').click(handler); you might need check other events (mousedown mouseup etc).

i need in figuring out design principle program. donot expect progamming code rather design , architecture theory. i programming in c language using socket api. want know how sql database, socket api, other language, etc needed complete it. if possible without lot of hassle, want upload on webserver. appreciate help. thanks. make small library has wrapper functions socket api, library sql database access, , else might use. these libraries should error handling, among other thing might do. emit diagnostics , decide whether continue or abort program, , it. build , test these libraries. then write program, is, reading , writing database , network , else might add. link against libraries when building. this program, understand question, going listen on port incoming connections, fork thread (or process), , keep listening. child process decide read or write , whether network or database. i hope simple enough homework started.

i using short script post data php processing page. function get(){ $.post('data.php',{name: form.name.value}, function(output) { $('#age').hide().html(output).fadein(1000); } ); } this send 1 input: $.post('data.php',{name: form.name.value}, i wondering how alter script send more 1 ? function get() { $.post('data.php', $('form').serialize(), function(output){ $('#age').hide().html(output).fadein(1000); }); } this assumes want send form inputs. alternatively, replace object literal such as... { name: $('input[name="name"]').val(), age: $('#age').val() }

i trying implement recursive tree structure arbitrary keys in java. want have tree<x,y> holds x , more (sub)trees, indexed set of y s. however, think since trees used indexing data in readonly disk file, tree should read-only. so, in order create them, made subclass, mutabletree , should allow editing operations on tree . here code: public class tree<c,k> implements serializable { protected c content; protected java.util.hashmap<k, tree<c,k>> nexts; protected tree () {} public c getcontent() { return content; } public java.util.iterator<k> getkeys () { return nexts.keyset().iterator(); } public tree<c,k> descend(k key) { return nexts.get(key); } } and mutabletree : public class mutabletree<c,k> extends tree<c,k> { public mutabletree (tree<c,k> par) { super(); this.content = par.content; this.nexts = par.nexts; } public

i have website users can "like" , "dislike" items. so each item, have data such total number of "likes" , % of total votes "likes". i'd calculate single score show users. using % wouldn't work because though item_a might have 90% of "likes" while item_b might have 80% of "likes", item_b should still rank in front of item_a if item_b has 10,000 total votes while item_a has 1,000 total votes. likewise using total "likes" wouldn't work because while item might have large number of "likes" shouldn't ranked high if % of "likes" low. what algorithm create single score out of data above? ideally score should "meaningful" or "normalized" in way. example if go imdb , see movie has score of 8/10, i'd know movie. on other hand if see score of 1,370 wouldn't know if or bad. there's couple of articles on how reddit sort of ranking here , ,

we've moved git still have systems depend on same data being in perforce i'm mirroring our git repo on perforce follows: git pull origin master git p4 rebase git p4 submit but problem i'm seeing every time run submit after pull origin tries re-apply every commit, ones submitted results in self generated conflicts. what's interesting works: git p4 submit <--- submit changes git p4 submit <--- no changes submit, recognizes it's date but throw in git pull origin master (even if there nothing new on origin) loses track , on next submit tries re-apply everything. example: git p4 submit <--- no changes submit git pull origin master <--- no activity on git server side no changes applied git p4 submit <--- tries re-apply changes submitted earlier is git pull origin master somehow wiping out git p4's notion of changes have been applied , haven't? you still pointing @ root. check branches point right place. use gitk --all
