when using git source control in vs2013, there way show diff between 2 arbitrary versions of source file in integrated editor (either built in functionality or free extension/plugin)? so far found out how display changes made since last commit or 1 commit next. if makes difference: i'm using vs c++. you can following: right click on file , choose "view history" on history tab choose 2 revisions you'd compare finally click on 1 of selected revisions , choose "compare..."

i'm investigating code has cache layer @ bottom level uses memorycache class. c# windows service app not web/iis. there section of code spawns off number of threads in creates , executes code in poc perform calculations. these stored in above mentioned cache layer. been seen looks cached values seem getting stored per thread , not @ apication level. thought memorycache singleton sit out side of individual threads. can confirm behaviour expected? many comments. a memorycache thread-safe there no reason assume it's singleton. if want different threads access same memorycache instance need give them reference same instance (either singleton (really bad) static (still bad) or through argument passing dependency injection (good)). the simple way (which use global state) access default memory cache: var cache = memorycache.default; // not idea , harder test, works you can find specific docs here . make sure configure in app/web.config file .

[edit]: dont have git console installed , therefore use git-plugin eclipse. i have several projects in eclipse / scala ide this: project 1 project 2 project 3 ... it can happen work on i.e. project 1 , changes. after work on project 2 , create changes. project 2 still faulty, have not finished changing code , want go bed or this. now click on project 1 -> team -> commit ... , down in file-window have done pops (project 1 - want upload, , project 2 - faulty , dont want upload). i aware there filter, can type in text , upload stuff project 1, have type everytime. if forget use filter? upload faulty code! also filter primitive, cant save templates later click on, have type correct(!) filter-text everytime want commit. so there way click on project , upload that? or keep other projects being uploaded until ready? it practice select files wanted commit. you can using command line using git add <file-name> git commit . think eclipse provide...

according struct tm documentation , value tm_sec can 0 - 61 , range include leap seconds in systems. how can detect if there leap second in system , in opensuse 13.2 machine specifically? leap seconds not related particular system. not directly informatic problem rather physical one. in ideal world, every clock accurate, there no reason leap seconds. in our restricted world, clocks tend deviate. moving system time, specially moving backwards can cause bad things happen. if batch task stores time of last run know files has been processed , because of clock moving backwards thinks time before last run, process again file may plain wrong. for reason, system developpers invented leap seconds allow system adjust system clock (of course slight deltas, enough if check clock on regular base) without having move backwards. as noted @supuhstar, operating system implementation of leap seconds. leap seconds have true physical origin , introduced compensate variation betw...

unless mistaken, speaker consists of floppy metal sheet has many positions. in java, there way manually set position of speaker? looking along these lines: ... speaker.setposition(byte position); // or setspeakerposition(byte position); ... thanks in advance! you mistaken. speakers not metal sheets. (if want understand how typical speaker works, try this: http://electronics.howstuffworks.com/speaker.htm ) there isn't way (move "plate" specific position) in java. doubt possible @ hardware level ... unless speaker implemented in rather strange way / expensive / inefficient way. on top of that, in typical computer audio system, there number of hardware , software components between program , speaker plate, none of designed used way.

i've read through related answers , articles on so, still doesn't : on chrome console if add 2 listeners output keycode on keypress , keydown events different keycode when key lowercase. when uppercase however, keycode appears same 2 events. example: document.addeventlistener('keypress', function(e){ console.log('keypress', e.keycode); }); document.addeventlistener('keydown', function(e){ console.log('keydown', e.keycode); }); // open console // typing 'a' in result field outputs 'keypress 97' 'keydown 65' // on chrome 42 console. activate uppercase, , typing 'a' outputs 'keypress 65' , 'keydown 65' // why ? so normal behaviour ? what's difference between keydown , keypress in .net? … explains well. keydown tracking key itself, not state of key. if press a keydown generates keycode of keys.a , if press shift + a keycode of keys.a.

i'm working on to-do list windows forms application in c# features date time picker, through research able find able set minvalue property of date time picker within designer tab of form. the plan set minimum date value date time picker through following code: this.startdatepicker.mindate = system.datetime.now; this.startdatepicker.value = system.datetime.now; this isn't issue, code fine , works. sets minimum value date time picker today, preventing user choosing date before date. however, issue reason designer tab decides reset , automatically remove code. i wondering if there way prevent designer tab changing minimum value date time picker? are modifying .designer.cs file? it's autogenerated , changes lost. you're not supposed edit manually. just move lines form constructor same effect, right after call initializecomponent() .

i working on project need deal 3 dimensional large array. using numpy 3d array of entries going zero, it's lots of wastage of memory. scipy sparse seems allow 2d matrix. there other way can store 3d sparse array? scipy.sparse has number of formats, though couple have efficient set of numeric operations. unfortunately, harder ones extend. dok uses tuple of indices dictionary keys. easy generalize 2d 3d or more. coo has row , col , data attribute arrays. conceptually then, adding third depth (?) easy. lil require lists within lists, messy. but csr , csc store array in indices , indptr , data arrays. format worked out years ago mathematicians working linear algebra problems, along efficient math operations (esp matrix multiplication).
