why log-line yield "true" here? added fragment tag "id"! fragmenttransaction ftrans = getsupportfragmentmanager().begintransaction(); ftrans.add(0, new myfrag(), "id"); ftrans.commit(); fragment frag = getsupportfragmentmanager().findfragmentbytag("id"); log.i("", "fragment null?

my code follows pca algorithm in order find eigenvectors , eigenvalues of 20000 *35 matrix. in order find eigenvector, need find covariance matrix, on calculation of order of 20000*20000. how process such huge matrix? using opencv code i believe question ill formed; if doing pca, 20000 * 35 matrix has 20000 observations on 35 variables (having 35 observations of 20000 variables not of use, i'm guessing it's not case). if such case, covariance matrix has size 35 x 35, not 20k x 20k. you can compute eigenpairs 35x35 matrix using qr algorithm, jacobi method or other eigenvalue/eigenvector approximating algorithm (many specific real symmetric matrices, case of covariance matrix).

so want jtexfield put text in jtextarea when enter key pressed cursor in it. can help? forget using keylistener swing components. this listener designed use awt components not provide reliable interaction mechanism jtextcomponents . use actionlistener instead - on vast majority of systems actionevent dispatched jtextfield when enter pressed. mytextfield.addactionlistener(new actionlistener() { @override public void actionperformed(actionevent e) { mytextarea.append(mytextfield.gettext() + "\n"); } });

let's have c dll functions like: void beep(); char* foo(char** whatever); now want able put dll on 1 machine (server) , call different machine (client). client can c# dll (and proxy server) needs regular c. ideal on client: mydllaccess remote = proxylib.getremotedll("192.168.1.10:12100", "mydll.dll"); remote.execute("beep"); // other machine beeps (uses getprocaddress find function) i know i'm reinventing com, etc, but..... there way? if not, why not , simplest way want since have dll? edit: needs work linux shared library, e.g. proxylib.getremote("192.168.10.12100", "mything.so") if need work across different oses, have hard time doing in pretty generic manner. can search "platform independent apis" in wikipedia article: inter-process communication idea. of find heavyweight. one simple way write ad-hoc http rest server (possibly json or xml interchange format). has advantage of being simp...
