postgresql - How to call a procedure as part of SQL statement using psycopg2 -

how go executing following insert using psycopg2? insert file (name, volume) values ('foo', (select id volume volume.name='bar')); this of course not work : cursor.execute("insert file (name,volume) values (%s,%s)","foo","(select id volume volume.name='bar')") select id volume volume.name='bar' replaced call stored procedure : lookup_vol_id('bar') thanks you use insert...select form of insert , e.g.: insert file (name,volume) select 'foo', (select id volume volume.name='bar'); or if name , column columns in table, in order, can leave out column names entirely: insert file select 'foo', (select id volume volume.name='bar'); either sql string can passed cursor.execute (without semicolon). as aside, looks perhaps volume column should renamed volume_id , since it's id column volume table.

stream - New to C++ and wondering what getline() and cin are doing in my code -

#include <iostream> #include <string> using namespace std; void computefeatures( string ); int main(int argc, const char * argv[]) { string name; cout<< "please enter full name" << endl; cin >> name; cout << "welcome" << name << endl; cout << "please re-enter full name: "; getline(cin, name); cout << "thanks, " << name << endl; return 0; } the output this: please enter full name john smith welcomejohn please re-enter full name: thanks, smith i guess question why cin print out first name , why getline() print second name. there way print both? cin takes first word it's input , second 1 separated space waiting in input buffer. getline() gets last name automatically , doesn't wait user input. you should use getline(cin,name) if want both first , last name in string variable name.

i sending emails webapp using javascript->firebase->zapier->mailgun. works. want send same (not customized each recipient) email 2 or 3 addresses. trying decide if should send multiple emails or send 1 email multiple addresses (separated commas) in "to:" field. 1) if send 1 email multiple email addresses, 1 bad email address (properly formatted, not deliverable) prevent other email addresses receiving email? 2) answer different if used multiple email addresses in "bcc:" field? 3) lastly, if 1 bad email address not prevent delivery addresses, there performance reason choose between sending multiple emails or sending 1 multiple addresses in "to:" or "bcc:" field?

let's assume have binding: <textblock text="{binding mybaseproperty.mysubproperty}" /> is possible tell wpf listen changes mybaseproperty ? , whenever mybaseproperty changes (re-)query mysubproperty of mybaseproperty ? the background behind question is: have view model contains property ( mybaseproperty ) pointing instance of class not implement inotifypropertychanged interface. datacontext textblock implement inotifypropertychanged interface , can therefore inform view changes mybaseproperty . if great if found accomplish kind of base-with-path-binding way can around valueconverters , extending viewmodel inotifypropertychanged -backed property wrappers mysubproperty . this fix you, you can listen mybaseproperty changed event , when happens .. you can force binding updates -- bindingoperations.getbindingexpressionbase(_mytextbox, textbox.textproperty).updatetarget();

Whats the Java EE package naming convention? -

-
i've been trying grasp better understanding of features belong java ee specification , standard java features of new application i'm working on, , i've noticed package structure seems bit muddled. an example, take packages: import javax.enterprise.context.sessionscoped; import javax.inject.named; both of these enterprise features 1 make s obvious existing in enterprise package. in java ee api specification here notice of features held within enterprise package. my guess of packages around before ee edition of java, kept structure backwards compatibility? still.. seems little odd. some apis in javaee stack not specific javaee , usable in javase. example cdi provides dependency injection, have in question javax.inject.named , can used in javase application well.

java - Is it possible to use JMH as a maven validation check? -

-
i have performance critical piece of code protect maven build step, i.e. jmh run , check performance hasn't degraded local changes. how can check such degradation using jmh? i've found few related links: perf testing in ci c++ ci perf metrics chapter: perf in ci ci junit , contiperf (uses @required() annotation) i've achieved automated performance testing before (though not java, , not in ci environment). 1 key point note never run absolute, since machine benchmark running on can vary. bogomips or test-dependent type of reference can used relative comparison. benchmark measured multiple of reference time, upper , lower bounds. while typically wary of benchmark slowing (degrading), it's important check upper bound well, may indicate unexpected speedup (better hardware support), should indicate per-system/architecture bound needs checked. i suggest build set of runner options via optionsbuilder , call run on within junit test. while author...

algorithm - Partition Frisbees C++ -

we have set f of n frisbee's in 2d. want partition f 2 subsets f1, , f2 no 2 frisbee's intersect in each respective subset. our function takes in input so: (x_j, y_j) centre of j-th frisbee, , rad_j radius of j-th frisbee. output should s_0 s_1 ... s_n-1, s_j = 1 if j-th frisbee in f1 , s_i = 2 if j-th frisbee in f2. if cannot partition f, return 0. ideally, algo should computed in o(n^2) time. i figured should use type type of matrix representation of graph, don't think need need construct graph, think bfs/dfs useful, i'm stuck on how elegantly in o(n^2). coding in c++ way. you on right track graph search. here's c++11, o(v^2), depth first search solution uses o(v+e) space. the dfs o(v+e) in time, generating adjacency lists o(v^2) obvious way. #include <iostream> #include <vector> #include <cmath> using namespace std; struct frisbee { double x; double y; double radius; }; int dfs(const vector< vector<int> ...

Java regex not matching, regex looks OK -

the following returns no matches: string patternstr = "((19\\d{2}|20\\d{2})-([0-2]\\d{2}|3[0-5]\\d)-(([0-1]\\d|2[0-3])[0-5]\\d[0-5]\\d))"; string fullpath = afile.getabsolutepath(); // fullpath should expand this: "/home/user1/2013-023-135159_abcd_001/file.txt" pattern p = pattern.compile(patternstr); matcher m = p.matcher(fullpath); if (m.matches()) { system.out.println("matches found"); } it should match date portion, 2013-023-135159. tested online , regex looks ok. you need use: m.find() instead of: m.matches() as regex matching parts of input string not expected m.matches() regex demo
