this question has answer here: pass parameter content script injected using chrome.tabs.executescript() 2 answers when i'm getting message popup want execute script, simply: chrome.runtime.onmessage.addlistener(function(message, sender, response) { chrome.tabs.executescript({file: "content.js"}); }); my problem: content.js needs data message . how pass it? try chrome.runtime.onmessage.addlistener(function(message, sender, response) { chrome.tabs.executescript({code: paramname=paramvalue},function() { chrome.tabs.executescript({file: "content.js"}); }); }); they both injected same isolated world, content.js can refer same variables.

i can't script wait until libraries copied on 'src/main/resources/libs' before starts jar everything. files copied on jar task think not waiting until files copied over? because not added jar. unless run script again :/ how fix this? task copydependencies(type: copy) { configurations.mylib 'src/main/resources/libs' } jar.dependson 'copydependencies' jar { manifest {} } to execution order right, processresources have depend on copydependencies . however, shouldn't copy src/main/resources . instead, libraries should included directly in jar, without intermediate steps: jar { into("libs") { configurations.mylib } } this assumes there custom process or class loader in place makes use of libraries in jar's libs directory. standard jvm/class loader ignore them.

the pickle module documentation says right @ beginning: warning : pickle module not intended secure against erroneous or maliciously constructed data. never unpickle data received untrusted or unauthenticated source. however, further down under restricting globals seems describe way make unpickling data safe using whitelist of allowed objects. does mean can safely unpickle untrusted data if use restrictedunpickler allows "elementary" types, or there additional security issues not addressed method? if there are, there way make unpickling safe (obviously @ cost of not being able unpickle every stream)? with "elementary types" mean precisely following: bool str , bytes , bytearray int , float , complex tuple , list , dict , set , frozenset i'd go far saying there no safe way use pickle handle untrusted data. even restricted globals, dynamic nature of python such determined hacker still has chance of finding way __builtin...

is there alternative tc-sfq (stochastic fairness queueing) allows configure limit based on packet size (total bytes) instead of packet count? the reason given packet size of 50 bytes, 1 htb class (rate=1000kbit) example dequeue 25 packets per 10ms, packet size of 1500 bytes 0.83 packets per 10ms. if set tc-sfq limit 25 packets, in worst case full queue take 300ms empty. -- this on linux 3.0.101, fq_codel doesn't work afaik. maybe has patch replaces sfq packet limit byte limit (similar pfifo vs. bfifo)? here's did: backported few changes kernel tree linux 3.0 sfq. since commit ddecf0... there backlog counter maintained each slot. needed change use depth parameter ( sfq_sched_data.maxdepth ) max backlog bytes : drop packet if slot->backlog >= q->maxdepth in enqueue function. with rate of 1000kbit can set depth 3750, means slot takes max 30ms empty. 2 large packets 1500 bytes each or 25 small ones 150 bytes each.

what best way 2d avatar creator without using game engine (ie. unity)? the avatar images basic body , placing different images different body parts - head, body, legs, arms, etc. layer different images on top of base image. can achieved in regular android app without using sort of game engine? there libraries done? for 2d avatar creator, using game engine job seems overkill (a library might well). coding scratch simpler having deal bunch of unnecessary tools @ end of day take space. also, more efficient, code bits need. because want make app android, i'd recommed doing using official android sdk . includes eclipse (a nice ide popular) no need worry on else download. sdk requires use java (if haven't learned language yet so. it's best , language you'll need know).

actually question not targeting play framework, general question async programming. i know in play, can use: ws.url(url).get() to make rest call async return promise/future.
