i want generate uniformly distributed random number -1 1 using c#, u(-1,1) in math sign. expected result should real number. user random.nextdouble() , multiply result 2 subtract 1. the code: var rand = new random(); var value = rand.nextdouble() * 2 - 1;

i'm new c, apologize if answer obvious, i've searched elsewhere. the libraries i'm including are: #include <unistd.h> #include <stdio.h> #include <string.h> #include <stdlib.h> #include <sys/wait.h> #include <fcntl.h> #include <sys/stat.h> the code failing is: char *user = getlogin(); char cwd[128]; if (user == null) printf("cry\n"); getcwd(cwd, sizeof(cwd)); printf("this prints\n"); printf(user); printf("this not\n"); printf("%s@myshell:%s> ", user, cwd); cry not print, should mean getlogin successful. segfault caused on printf(user); further testing shows folling block prints entirely printf("this prints\n"); printf(user); printf("this prints\n"); but folling block print prints end segfault without showing user printf("this prints\n"); printf(user); edit: sorry wasting t

i have compiled exe file matlab script. exe seem run fine on own. produces wanted output without error message. when run exe-file within program exe file produces following error: too many input arguments error in mclfreestacktrace any suggestion welcome.

i have modify existing code , stumped on getter setter. how add setter code? public virtual string sku { { return product.id.trim(); } } depending on want in setter. if want assign value product.id should this: public virtual string sku { { return product.id.trim(); } set { product.id = value; } } in case set private field this: private string _sku; public virtual string sku { { return product.id.trim(); } set { _sku = value; } } but bit akward have setter set field, whereas when getting value different. the natural solution seem be: private string _sku; public virtual string sku { { return _sku.trim(); } set { _sku = value; } } but not know exact rules of business logic.

i want make foreach each item in list. doesn't seem possible. or doing wrong? the c# class group public int _id; public string name; public list<subgroups> subs; the c# class subgroup public int _id; public string name; normally this // make group = groups foreach(var g in group) { foreach(var s in group.subs) { // } } but can't call group.subs or @ least won't show. possible? foreach(var g in group) { foreach(var s in g.subs) { // } } you have use variable in outer loop; current variable in iteration.

i'm working on script connect external ftp, download .csv file , import each record .csv table. i've written script so, have 1 major issue. 1 of columns in .csv file description column which, guessed it, contains commas. this description column wrapped in quotation marks (") i've read solution, column contains measurements, i'd have escape " well. the easiest solution see change field separator uncommon, such | or ^. can tell me if can accomplished in php script? if has alternate suggestion, please let me know, direction here helpful! thanks!

i have set of parametric curves , reference curve, , want see ones intersect reference curve. for example, let's function1's parametric curves , function 2 reference curve. function1[x_,a_]:=x^2+a function2[x]:=1 how can know function1 intersect function2 "in clean way". tried using findroot: in:= findroot[function1[x, 1] == function2[x], {x, 1}] out= {x -> 1.} it works case, in case not work, mathematica provides me absurd value, error message. in[485]:= findroot[function1[x, 4] == function2[x], {x, 1}] "during evaluation of in[485]:= findroot::lstol: line search decreased step size within tolerance specified accuracygoal , precisiongoal unable find sufficient decrease in merit function. may need more machineprecision digits of working precision meet these tolerances. >>" out[485]= {x -> 3.09187*10^-6} instead of having absurd value (in case not intersect) or exact value (in case intersect), "true" or "false&

i have setup 72 machines take jobs rabbitmq queues , perform crud operations on sharded mongodb on 4 machines , arbeiter, want know if makes difference/sense let 1 machine handle crud operations, running on same network. on side note reason thinking because makes tracking progress easier. four instances light sharded solution, perhaps talking replication ? in mongodb concept of replication used high availability, not performance. minimum recommended configuration 3 nodes, 1 primary, 1 secondary , arbiter. purpose of arbiter being handle elections on node primary, breaking deadlock on 2 nodes handing majority of votes one. more stable replica sets have @ least 3 nodes of primary, secondary, secondary..., , possibly arbiter, arbiter again used have odd number of votes giving majority 1 node in election. in sharded configuration, collection split determined shard key across shards in cluster. main purpose of sharding when data has working set larger available ram on
