i need arrange list have distinct object items largest object x property. example: have list of objects: mylist : object[0] : name: dani x:3; object[1] : name:dani; x:1; object[2]: name:joey; x:5; object[3]: name:joey; x:1; i need find distinct objects largest x values new list 2 objects so: new list: object[0] :name:dani;x:3 object[1] :name:joei;x:5 how can find new list? lambda ex nice... myobjects.groupby(o => o.name).select(g => g.orderbydescending(o => o.x).first()) seeing don't provide details of linq provider using, best general approach. can speed things in linq2objects using maxby extension method in morelinq : http://code.google.com/p/morelinq/ myobjects.groupby(o => o.name).select(g => g.maxby(o => o.x))

when phone receives text message, upload database. on tablet should notification new message possible. how efficiently check new messages database? don't think background process queries database every few seconds efficient @ all. drain battery , it's huge waste of network. have static broadcastreceiver in app listener. if text message comes in receiver started , onreceive() called. can invoke service/ activity save database , put notification. here's nice tutorial started.

i have form this: <form> <select name="user_id[]"></select> <select name="user_id[]"></select> <select name="user_id[]"></select> <select name="user_id[]"></select> <select name="tag_id[]"></select> <select name="tag_id[]"></select> <select name="stack_id[]"></select> <!-- ... etc. --> </form> i want jquery collection consisting of first multivalue elements name: <form> <select name="user_id[]"></select> <!-- --> <select name="user_id[]"></select> <select name="user_id[]"></select> <select name="user_id[]"></select> <select name="tag_id[]"></select> <!-- --> <select name="tag_id[]"></select> ...

i have sifted through lots , lots of python/unicode explanations can't seem make sense of this. here situation: i pulling loads of comments off reddit (making bot) , store them in mongodb, need able print out comment trees in order manually check what's going on. i have had no problems far putting comments db, when try print stdout cp1252 charset having trouble characters doesn't support. as have read, in python 3 internally (strings) stored unicode, it's input , output must bytes, fine - can encode unicode cp1252 , in couple of situations see \x** characters don't mind - guessing represent out of range characters? the problem printing out comment trees (to stdout) using \n (linefeeds) , tabs easy over, apparently when encode unicode string newline escape sequences escapes them printed literals. for reference here encode statement: encoded = post.tree_to_string().encode('cp1252','ignore') thanks edit: what want is |parent c...

for example, if visit example.com website cannot visited. instead, have explicitly use www.example.com in order access correctly, fact turns out annoying since people don't want type www time. what's solution here? i'm using linux servers. you have add a record on dns service provider , , host name should www . this: first column host name , second record type , ignore third , last 1 (different provider differs), fourth ip address , pointing server.

well, i've been asking myself question quite long time now. i started using gnu fortran compiler ( gfortran ) , quite happy. started hearing intel fortran compiler ( ifort ) better because optimized intel processors (and therefore optimized computers today consequence intel has greater share of market). after started using ifort , truth i'm not happy because not detect errors gfortran (i.e. question: "reference passing changing values of matrix" ). it true there other fortran compilers but, actually, never use other gfortran , ifort . so ask you: advantages , disadvantages of each one? best one, if optimization not important? in opinion, best stick standard you're comfortable with, , write code conforming standard. then, choice of compilers dictated support said standard. here extensive list of compiler support 2003 , 2008 standards. i myself used g95 lot because liked debug messages. nowadays, commonly use fortran 2008 features, , use ...

i'm new ansible. i'm trying start process on remote host using simple ansible playbook. here how playbook looks like - hosts: somehost gather_facts: no user: ubuntu tasks: - name: change directory , run jetty server shell: cd /home/ubuntu/code; nohup ./run.sh async: 45 run.sh calls java server process few parameters. understanding using async process on remote machine continue run after playbook has completed (which should happen after around 45 seconds.) however, playbook exits process started run.sh on remote host terminals well. can explain what's going , missing here. thanks. give longer time async 6 months or year or evenmore , should fine. or convert process initscript , use service module. and add poll: 0

i'm trying use code below , works way want alerting honda, toyota, , ford in second each(). first 1 outputs 0. why doing that? var cars = { honda : {0: "accord", 1: "prelude", 2: "civic"}, toyota: {0: "camry", 1: "corolla", 2: "brz"}, ford: {0: "mustang", 1: "focus"} } $(cars).each(function(key, value)) { alert(key); }) $.each(cars, function(key, value) { alert(key); }) your first example outputs 0 because when $(cars) , you're wrapping cars object in jquery object, object 1 element index 0. also should note distinction between both "each" methods: jquery.each() or $.each() : a generic iterator function, can used seamlessly iterate on both objects , arrays. .each() : iterate on jquery object, executing function each matched element.

what best way load full page of data including external js files current page? know how way better? iframe or div? @ moment jquery ajaxing data div. toggling div when not needed. an iframe used used containing media files/content. such pdf, flash, image, video, etc. iframe can used containing html, wont great deal have great result(except need it). if want embed/attach external html page think should use div element. if want add media content web page, should use iframe element. can create toggle button using javascript. js want embed can embedded on main page(master page contains attached files/contents) or on page want embed. careful, don't attach 2 or more js has same function, make browser confused (ex : attach jqueryui-1.9.0 , jqueryui-10.0.2).

i need write program using mips take string , switch uppercase letters lower case , lowercase letters uppercase. instinct write if statements using letter numerical values wondering if there better way go this. yes, there better way of doing this! ascii values of corresponding upper , lower case alphabetical characters differ 0x20 . instance, 'a' = 0x41 , 'a' = 0x61 . basically, sixth bit set lower case characters, , cleared upper case. the simplest implementation uses bit-bashing trick - if can identify character letter, can upcase using: ch &= ~0x20; or downcase with: ch |= 0x20; remember, won't work other alphabetic ascii characters. can check whether character matches (ch >= 'a' && ch <= 'z') || (ch >= 'a' && ch <= 'z') . another approach avoids if entirely build 256-entry table consisting of intended output each character, , indexing each character. may slightly more e...

i have form in there 10 fields, of them drop downs. halfway through there 1 drop down list mandatory , next link adding new item drop down. add new link goes form entry can made , entry reflected in drop down. want when form comes original form values in fields prior drop down must retained. remember link element data not getting posted values cannot taken session without pressing submit button. tried session not working because said without pressing button values not posted no question of getting them in session. or hint appreciated. problem happens on social networking sites. when start filling profile somewhere in between asked upload image. link takes page after loading photo come original form , values still retained. form still not complete , not submitted filled values there. here code drop down list think code not of help. scenario important in case: <tr> <td> dealer name </td> <td> <?php if(isset($_get['n...

consider following loop: (i =1; <= n; i++) { (j = 1; j <= i; j++) { k = k + + j; } } the outer loop executes n times. i= 1, 2, ..., inner loop executed 1 time, 2 times, , n times. thus, time complexity loop t(n)=c+2c+3c+4c...nc =cn(n+1)/2 =c/2(n^2)+c/2n =o(n^2).. ok don't understand how time complexity, t(n) determines c+2c+3c. etc.. , cn(n+1)/2? did come from? the sum 1 + 2 + 3 + 4 + ... + n equal n(n+1)/2, gauss series . therefore, c + 2c + 3c + ... + nc = c(1 + 2 + 3 + ... + n) = cn(n+1) / 2 this summation comes lot in algorithmic analysis , useful know when working big-o notation. or question summation comes @ all? hope helps!
