i'm writing simple script cd multiple folders file, cd doesn't work. i have tried solutions in why doesn't "cd" work in bash shell script? , shell script change directory variable but didn't work. here script: cat filename.txt | while read line; echo $line line=$(echo $line | tr -d '\r') cd "$line" done + inputfile=drugs800folders.txt + ifs= + read -r line + line=cid000000923 + cd cid000000923 + awk '$11 < 0.05 {print $1 $2 $3 $8 $10 $12}' groups.txt + ifs= + read -r line + line=cid000001003 + cd cid000001003 filterfuncoutput.sh: line 5: cd: cid000001003: no such file or directory + exit @charles duffy works, , did awk first folder in list, not remaining folders after first line first line selects first file in list ? unless have lastpipe shell option set (and prerequisites operation met), elements of shell pipeline in bash run in own subshell. consequently, side effects o...

i try simple division of polynomials in 2 variables using sage. unfortunately, unexpected result, illustrated in code below. tried several different ways instantiate ring , variables, result stays same. using %-operator rest of division yields same results. ideas? r, (x, y) = polynomialring(rationalfield(), 2, 'xy').objgens() t = x^2*y^2 + x^2*y - y + 1 f1 = x*y^2 + x f2 = x*y - y^3 (q, r) = t.quo_rem(f1) print "quotient:", q, "reminder:", r assert q == x , r == x^2*y-x^2-y+1 (q, r) = r.quo_rem(f2) # error, expected q = x, r = -x^2+x*y^3-y+1 print "quotient:", q, "reminder:", r assert q == x , r == -x^2+x*y^3-y+1 output: quotient: x reminder: x^2*y - x^2 - y + 1 quotient: 0 reminder: x^2*y - x^2 - y + 1 --------------------------------------------------------------------------- assertionerror traceback (most recent call last) <ipython-input-8-861e8a9d1112> in <module>() 10 (q, r) = ...

this homework, , becoming little frustrated how can't figure out simple. to simplify code, have 3 files right now: 1 class add() method created among other things, 1 file tests (made prof), , 1 creates object (which won't post, b/c working). here's add() function. edit 2: i'm going add method prints array, maybe that's problem? public class population { private person[] pop = new person[15]; private int numpop = 0; public void add(person c){ // object created in class, works fine for(int = 0; < pop.length; i++){ if(pop[i] == null) { pop[i] = c; numpop++; } else {} } public string listpeople(){ system.out.println("population "+numpeople+" people follows:"); int = 0; while (i<numpeople){ system.out.println("a "+pop[i].getage()+"year old person named "+pop[i].getname()); i++; //fyi methods wor...

i'm making code should print text on console , every letter should came little delay. i've tried this from time import sleep print "h", sleep(0.1), "e", sleep(0.1), "l", sleep(0.1), "l", sleep(0.1), "o" but puts random "none" there. should do? please :?: sleep returns none, gets printed. print each char without newline , sleep: import sys time import sleep c in "hello": print c, # note comma sleep(0.1) print # final newline but avoid spaces inbetween, you'll have this: import sys time import sleep c in "hello": sys.stdout.write(c) sleep(0.1) sys.stdout.write('\n') depeding on environment, might need flush stdout buffer: import sys time import sleep c in "hello": sys.stdout.write(c) sys.stdout.flush() sleep(0.1) sys.stdout.write('\n') sys.stdout.flush()

i trying figure out best way handle multiple connections c++ tcp server. stumbled upon epoll() sadly it's available linux , i'm doing on windows. after research seems best way handle sockets on windows use of i/o completion ports. use them, client application uses send() , recv() (i cannot change that), meaning need use same functions send , receive data client. these functions don't seem used iocp ( wsasend() / wsarecv() used instead). i'd know if there's still way able use iocp send() , recv() ? or should other methods? i need use same functions send , receive data client that's incorrect. client has no idea how data , out of tcp connection, either way same exact tcp segments sent across network. if server i/o bound, wsaasyncselect and/or wsaeventselect work (and save trouble of multithreading). compute-bound services iocp worthwhile, because distribute work items available thread simultaneous requests can spin , calculations...
