java - Lock dependencies by secure checksum in Maven -

when distribute source project pom can define dependencies version strings. build download dependencies if not in local repository, verify checksums of downloaded files metadata same repository ( -c ). however build download dependencies number of public repositories (and proxies) , users @ mercy of public services if return unmodified files. i have way record checksums of build dependencies , ship them pom (so sure files unaltered dont need ship copy of local repository builders). is there maven way this? similiar that, there easy way archive dependencies (copy of local repository used artifacts , metadata files) can repeat build when central repositories fail or ship them offline customers? (both without need repository proxy if possible. know can build that, wonder if there infrastructure in maven already. maybe shipping local repository contain metadata files or similiar?) nb: not looking createchecksum on generated artifacts, on locking checksums of used dependencie

i have list of 2d integer coordinates (coordinate pairs). i'd read these in and, later, determine if point has been read. the integer data may fall anywhere within range offered integer data type, number of actual data points small. therefore, using 2d array track points have been read impractical. set seems way of doing this. my current code accomplish follows: #include <set> #include <iostream> using namespace std; class grid_cell{ public: int x,y; grid_cell(int x, int y) : x(x), y(y) {} grid_cell(){} bool operator< (const grid_cell& a) const { return y<a.y || x<a.x; } }; int main(){ set<grid_cell> bob; bob.insert(grid_cell(1,1)); bob.insert(grid_cell(-1,1)); bob.insert(grid_cell(1,-1)); bob.insert(grid_cell(-1,-1)); cout<<bob.count(grid_cell(1,1))<<endl; cout<<bob.count(grid_cell(-1,1))<<endl; cout<<bob.count(grid_cell(1,-1))<<endl; cout<<b

i'm writing web app run on heroku using postgresql. on servers, environment variable provided like: export database_url=postgresql://localhost:5432/iqtest they advise when running app locally, should disable usual postgres setup used in debian/ubuntu, , run server locally 'to avoid permissions issues'. you can create database like: /usr/lib/postgresql/9.1/bin/initdb pg and run server like: /usr/lib/postgresql/9.1/bin/postgres -d pg this works fine, wonder if it's possible system setup instead. i can't find simple explanation of how debian/ubuntu standard setup supposed work or how you're supposed use it, , experiments have ended demanding password, , warning me it's going write disk plaintext. has managed standard setup work heroku-style app without having appalling? as secondary question, there graphical (or text ui) browser/editor postgres tables? can use psql , sql commands, point , click nicer. pgadmin3 won't connect database

there lot of files, each of them need read text content, processing of text, write text (replacing old content). know can first open files rt read , process content, , close , reopen them wt , not way. can open file once read , write? how? see: http://docs.python.org/2/library/functions.html#open the commonly-used values of mode 'r' reading, 'w' writing (truncating file if exists), , 'a' appending (which on unix systems means writes append end of file regardless of current seek position). if mode omitted, defaults 'r'. default use text mode, may convert '\n' characters platform-specific representation on writing , on reading. thus, when opening binary file, should append 'b' mode value open file in binary mode, improve portability. (appending 'b' useful on systems don’t treat binary , text files differently, serves documentation.) see below more possible values of mode. modes 'r+', 'w+' ,

javascript - How can I know a 2 last pressed key on a keyboard -

-
is possible know, 2 last keys pressed on keyboard? how can it? need compare keys, , if same - make function. example, if press enter - first function, if after enter press space- second function. if after enter press ctrl - third function. so, hink onw way - make 2 var current , previous key value, , make if else if function :-) way, how current key value $('#text').keydown(function(event) { $('#show').text(event.keycode); }); or, better question! (i saw right now) directly in editor, after press doublespace - jump anothe line in live-preview. how works? i'm not sure, thinks need same. thank much! you start very simple jquery plugin: (function($) { $.fn.keywatcher = function() { return this.keydown(function(evt){ var $this = $(this); var prevevt = $this.data('prevevt'); $this.trigger('multikeydown',[prevevt,evt]); $this.data('prevevt',evt); });
