multithreading - Where to begin serious concurrent (multi-threaded, parallel ?) programming -

-

i want begin multi-threaded/parallel/concurrent programming in real world. mean trying solve real problems in parallel , concurrently , not learning low-level details of pthread or mpi, locks, races , or academic, text-book examples. regarding low level mechanism of parallel programming, in fact rather not know them , stick more actor model :).

i have heard programming languages inherently looking , paradigm @ problem @ hand in parallel (concurrent, multi-threaded, multi-processed) fashion , provide language level tools , constructs implement task in parallel (e.g. erlang has concept of process language construct?).

i fancy language type system of scala ... know php , used lot of coding in c/c++. have working knowledge of scala , java , can read haskell i'm not particularity proficient @ it. i'm quite familiar functional paradigm , i'm willing learn more. interested in high level theoretical discussions parallelism/concurrency.

i'd mention first off parallel != concurrent. they're closely related concepts, parallel computation distinction concurrent computation in parallel flows of control happen simultaneously while concurrent may interleaved possibly parallel. fine hair split, 1 that's important understand.

... provide language level tools , constructs implement task in parallel (e.g. erlang has concept of process language construct?).

an erlang 'process' light-weight, memory isolated green thread. language provides no shared memory constructs; data passed between concurrent flows of control via 'messages'. notice said 'concurrent'. erlang explicitly designed concurrent language and, happens, schedule flows of control--which map 1:1 onto processes--in parallel. erlang not give explicit control on scheduling, unlike threading model.

it's hard know you're looking for--your question rather broad--but of languages you've mentioned (except maybe php?) allow exploit multiple cpus surely sitting in computer. pick several focus on, expect spend several years studying , go it.

java - activate/deactivate sonar maven plugin by profile? -

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

java - What is the difference between String. and String.this. ? -

-
this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
