version control - Insight on handling static library revisions (i.e. binaries) with git -


i'm looking insight on how handle git repositories each utilize (large) static library, , have concerns solution thought about.

suppose lots of separate projects, under version control, each rely upon large static library under (very) active development. let's repos a, b, c, ... have own development teams, , rely on lib. now, lib project under version control, , being worked on yet team. let's assume teams can't/shouldn't access source lib, accessing headers , static library binaries ok.

now, when first thought how organize sort of situation in git repos, submodules came mind. here's quick diagram:

"lib" repo:     dist/ -> "lib_dist" submodule     headers/     sources/     ...  "lib_dist" repo:     binaries/ (output "lib" repo build process)     headers/ (copied "lib" repo in build script)  "a" repo:     headers/     libs/         lib_dist/ -> "lib_dist" submodule     sources/  "b" repo:     (looks "a")  "c" repo:     (again looks "a")

the build process lib compile source static library files , copy headers dist subfolder. subfolder submodule of lib repo, , we'll call lib_dist repo. lib_dist repo added a, b, c, ... submodule.

advantages: developers on teams a, b, c, etc. not have compile large static library themselves, can't see source code lib, , a, b, c, repos able compile no matter revision developer using. mean if developer on project a needs go older revision, can git checkout <rev_hash> . , git submodule update; if lib_dist has changed since time <rev_hash> committed, submodule revision adjusted match 1 present @ time <rev_hash> made. means lib_dist headers , binaries "just work".

disadvantages: on time (and exacerbated due active development), lib_dist repo grow very large, git isn't meant store binary files under version control. git repos on 1gb in size can tax server, , pushing/pulling become time consuming , resource intensive.

so, in sort of context, "best practices"? git right tool? better tool exist (i'm open other version control tools)? nothing came mind me, short of manually managing lib versions. but, seems me manually managing to-be-compiled-against version of static lib so... 20th century (and error-prone).

thanks!

edit: should add these projects written in c/c++.

i not recommend using git managing library binaries, gits core feature versioning not need. if building on multiple platforms, have provide separate binaries each platform.

what looking seems kind of automated dependency management e.g. maven java.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

first of all, thank being patient know simple question more couple of weeks' experience figure out. i've seen folks persevere , helpful on here , hope you're willing me. here fiddle: http://jsfiddle.net/65uzf/ here 1 of places searched answers on here: ( vertically center image thumbnails fix-sized div ) tried solutions on there , didn't work out me. i've searched ~4 or 5 others, , been unsuccessful those, too. what want take large image (what linked background-image #ysypic , #tabpic divs) , display thumbnail version of image in confines of divs have set it. is, using background properties have laid out in css, portion of image displays inside of circular divs. without these properties, display defaults smaller section of image [presumably pi*(50^2) area in top left] terrible resolution. i not care if entire image doesn't display inside of circles (it won't, given difference in shape), , overflow not being displayed fine. want able see figu

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
