i have been using python year now, coming java background. found python quite easy learn because of focus on readability , simple design. thing don't understand python why language focuses heavily on readability, uses non-descriptive names modules, functions, constants etc.. 1 thing java descriptive class/attribute/method names (i objective-c more reason). seems python programmers in general seem have taken c type approach naming use short names possible everything. know wants little typing possible lot of programmers spend majority of time reading code rather writing find choice between short non-descriptive names , long descriptive names, easy 1 make. (i longer descriptive names xd) a few examples, looking @ modules in standard library, sched — event scheduler, have been eventscheduler? asyncore — asynchronous socket handler, asynchronoussockethandler? imghdr — determine type of image, determineimagetype? pickle? i know isn't huge issue find myself more not hav

basically, i'm asking if salting password appending hashed version of end of secure salting different string. so: is this: $pass = "pass"; $salt = sha1(md5($pass)); $pass = md5($pass.$salt); as secure this? $pass = "pass"; $salt = "4d9ds*^dkrui45^#dkd*3fd8&!dlvd*"; $pass = md5($pass.$salt); the first example secure hashing without using any salt @ all, because still requires password , nothing more crack. in other words, applying hashing functions same thing few times more. a better bet still create salt each user , store alongside, separately. fixed salt alright, guess, because cannot use password determine salt. however, generating unique salt each user better because take more information password crack (e.g. username, date registered, or other info).

i have interface want able statically link modules. example, want able call functions (albeit in seperate files) called foo or match prototype, make call function in file without header in other files. dont impossible since found hack can it, want non hacked method. (the hack use nm functions , prototypes can dynamically call function). also, know can dynamic linking, however, want statically link files. ideas? this common in writing test code. e.g., want call functions start test_. have shell script grep's through .c files , pulls out function names match test_.*. script generates test.c file contains function calls test functions. e.g., generated program like: int main() { inittestcode(); testa(); testb(); testc(); } another way use linker tricks. linux kernel initialization. functions init code marked qualifier __init. defined in linux/init.h follows: #define __init __section(.init.text) __cold notrace this causes linker put fun

i having trouble figuring out how (and where) order subcollection in linq/ef query. basically have collection of subscriptiontypes, each having own collection of subscriptions. each subscription in collection ordered numberofmonths. here current query: public iqueryable<subscriptiontype> subscriptiontypesbyproperty(string propertycode) { return in db.subscriptiontypes.include("subscriptions") a.subscriptions.any(x => x.propertycode == propertycode) select a; } i subscriptions ordered numberofmonths. tried this: public iqueryable<subscriptiontype> subscriptiontypesbyproperty(string propertycode) { return in db.subscriptiontypes.include("subscriptions") a.subscriptions.orderby(q => q.numberofmonths).any(x => x.propertycode == propertycode) select a; } .. did not order subscriptions correctly. does know of easy way this? update: subscriptiontype , su

i have bunch of forms have various input elements. want sanitize these on server side ( yes , i'm using server-side javascript) use these inputs parameters, , prevent special characters malformed. before go, "this belongs not in realm of javascript", etc., etc. i using multi-million licensed software solution, has javascript apparently has no standard functions out of box. so, whatever using, can assure you have never touched or heard of it. , supports server side javascript, because well, language cool. my first objective sanitize data before goes in database, , love way example how ruby labels foreign data: tainted. , rather have no tainted data. google , copy paste poor regex here , there, , got sad example. however, have function said "well, takes off 70% of possible stuff data , pretty darn sanitize". basically string these elements should escaped , assume best practices existing wish of mine. function sanitize(mystring) { ... ; return mystrin

i not know php i'd love 1 simple thing: access php page within <img src="/myhumbleimage.php" /> , i'd have image returned url. i came with: <?php header('content-type: image/png'); readfile('i' . rand(1,3) . '.png'); exit; and works: avatar selection http://vercas.webuda.com/img.php?.png (reload page few times!) check out readfile() . the basic idea send appropriate mime type headers (using header()) deliver file contents using readfile() . for example <?php // myhumbleimage.php // whatever myhumbleimage.php before image delivered header('content-type: image/jpeg'); readfile('path/or/url/of/image/file.jpg'); exit;

i have string: string somestring = "\\\\tecan1\\tecan #1 output\\15939-e.esy" i need extract 15939 it 5 digit number, preceeded '\' , "-" after it string result = path.getfilename("\\\\tecan1\\tecan #1 output\\15939-e.esy").split('-')[0]; perhaps?

i have list of international phone numbers , list of country calling codes . identify country numbers can't find fast , elegant way it. any idea? got have hardcoded check (eg. "look @ first number, @ second number: if it's x check third number. if second number y country foo", etc.). i'm using php , db (mysql) lists, think pseudocode help. i after similar this, wanted determine region/state - if available. in end hacked based on tree of digits leading digits (spurred on description @ wikipedia ) my implementation available gist .

i have following function: library (reshape) phenotype <- rnorm (100) data <- matrix(rnorm(1000), nrow = 10, ncol=100) spearman.p <- reshape( melt( apply(data, 1, function(y){ cor.test(y,phenotype,method="spearman") }[c("p.value", "estimate")] ) ), timevar="l2", idvar="l1", direction="wide" ) that know if there more efficent way of getting out p.value , estimate "apply"ed cor.test can provide suggestions? this more compact , delivers p.values duplicated data. wanted?: dtt <- do.call(rbind, apply(data, 1, function(y){ cor.test(y,phenotype,method="spearman") }[c("p.value", &qu

i have datepicker in activity. works fine except when user enters date via keypad , not use + or - buttons change date. date returned when user edits via keyboard datepicker initialized with. when debug notice ondatechanged() callback never called except when date change using buttons. yep, meet issue too. datepicker save change if remove focus active edittext. have run "mdatepicker.clearfocus();" before date it.

i developing tool may got more million data fill in. current have designed single table 36 coloumns. question need divide these multiple tables or single?? if single advantage , disadvantage if multiple advantage , disadvantage and engine use speed... my concern large database have atleast 50000 queries perday.. any help?? yes, should normalize database. general rule of thumb if column isn't foreign key contains duplicate values, table should normalized. normalization involves splitting database tables, , helps to: avoid modification anomolies. minimize impact of changes data structure. make data model more informative. there plenty of information normalization on wikipedia . if have serious amount of data , don't normalize, come point need redesign database, , incredibly hard retrospectively, involve not changing code accesses database, migrating existing data new design. there cases might better avoid normalization performance reasons,

i'm using standalone autotest in projects along minitest . in 1 of projects, have single file ( validation.rb ) validates document different internal format levels. (a level 2 document has more features level 1 document.) testing validation particular level requires repeatedly loading in known-valid document, subtly mutating in broken way, , ensuring broken. in short: class testvalidation < minitest::unit::testcase def setup @l1 = document.load( l1doc ) end def test_valid assert @l1.valid_level_1? end def test_unbalanced_data @l1.instance_eval{ @tracks[0].data.pop } refute @l1.valid_level_1?, "validation must ensure tracks have same amount of data" end # many more tests level 1 here end the problem autotest (as far can tell) knows tests run based on name of test classes. testvalidation have tests automatically run when validation.rb changed. without autotest, have named above class testl1validation , , created new class test

my master git branch seams have errors i'd recheck, re-merge or possibly clone dev branch on master branch master branch copy of dev. how can that? thx. if problem checked-out files don't match branch, use git reset normally: git reset --hard head that should need. however, if still want overwrite master dev, read on. if want overwrite master branch contents of dev branch, use git reset so: $ git checkout master $ git reset --hard dev and if want push somewhere else: $ git push origin master note if dev branch doesn't fast-forward master branch (which i'm guessing won't, since said master branch has screwed stuff in it), you'll need add --force flag push overwrite on remote: $ git push origin master --force note, however, can involve of normal caveats of rewriting history la git rebase - if else uses remote, they'll need deal equivalent of upstream rebase. to avoid problem in future, advise friend using --force nev
