i using ipdb debug python script. i want print long variable. there ipdb pager more or less used in shells? thanks you might want create function accepts text, puts text temporary file, , calls os.system('less %s' % temporary_file_name) . to make easier everyday use: put function file (e.g: ~/.pythonrc ) , specify in pythonstartup . alternatively can install bpython ( pip install bpython ), , start bpython shell using bpython . shell has "pager" functionality executes less last output.

tcp segments include checksum field of 16-bits , ip datagrams , udp packets. @ link layer, crc checksum 4 bits (for 802.3 , 802.4). on extreme part of spectrum, computing parity bit might yield lot of false-positive, packet looks valid in fact not, because number of bits have been altered. on other hand, having 16-bit checksum when 4 bits suffice waste of memory/bandwidth/money. how evaluate how many bits checksum should be? ps: i have taken internet stack example, applies protocol/software really. ps2: not sure forum use. first, quick nomenclature correction - checksums , crcs 2 different approaches trying solve same problem: detect bit errors occurred during data transmission in noisy channels. in general crcs more powerful detecting errors @ expense of more complexity. selecting right error detection scheme requires knowledge channel (e.g. error probability) , noise characteristics (e.g. impulsive, bursty). there papers out there problem analyzed in detail , g...

is @ reasonable low of test error rate? doubt it, because test error rates listed on mnist database website higher this, evidence otherwise seems irrefutable. using 2 layer net 100 hidden units. using no regularization. initialize small random weights , use nesterov momentum method on mini-batches. training error rate 0.0000667 (4 training examples misclassified). average cross entropy loss on training examples 0.00410, , same on test examples 0.207. here link original metaoptimize post . edit: i found result must have missed on mnist page: 2-layer nn, 800 hu, cross-entropy loss, obtains test error rate of 1.6%. guess other results high error rates there make point types of fancy modifications neural nets harm performance. net hasn't done better 1.6%, believe result more readily.

is there wrong in wpf setting owner property of window parent in parent's constructor? there shouldn't be, right? why getting xamlparseexception following code? public partial class mainview : window { private readonly ownedwindow owned; public mainview() { initializecomponent(); owned = new ownedwindow(); owned.datacontext = datacontext; var window = getwindow(this); owned.owner = this; //setting window causes same error ... } i should clarify removing owned.owner = this; removes runtime error. the details of exception: xamlparseexception unhandled the invocation of constructor on type '...mainview' matches specified binding constraints threw exception. actually , looked @ inner exception, , says: cannot set owner property window has not been shown previously. so i'm looking now. the problem because wpf creates native window first time wpf window shown, c...

new pointers , unsafe world in c#. going through getting memory address of variables via pointers, move things around bit here , there etc; learning. static unsafe void m() { var = 1; var p = &i; //gets memory location of variable here //how write location p, value of 100? } i wondering if there way write specific location well? helps great deal see what's going around if can read , write @ same time. no practical purposes, learning. or not possible c#? you need dereference pointer * operator. ex: *p = 100;

yeah question topic has been discussed many times. , i'm clear difference. i've 1 doubt related example in book. this question related my previous question , presented 2 classes taken example in book c++ primer. in reference classes, book quotes following paragraph, specially related declaration of member function of windowmanager class friend function. here's says: making member function friend requires careful structuring of our programs accommodate interdependencies among declarations , definitions. in example, must order our program follows: first, define window_mgr class, declares, cannot define, clear. screen must declared before clear can use members of screen. next, define class screen, including friend declaration clear. finally, define clear, can refer members in screen. the code presented in question follows structure only. seems not working out. makes me think if above points misguiding or didn't implement correctly. ...

i'm trying make connection between function in 1 class can call in class. answers i've found either specific or maybe i'm missing because cannot life of me figure out i'm doing wrong. also, i'm bit new boost library please excuse dumb questions may ask. the setup workflow this... class myclass : public baseclass { void setup(); void myfunc(datatype); otherclass myotherclass; } void setup() { othernamespace::addlistener(this, myotherclass); } namespace othernamespace { class otherclass { signals::signal<void (datatype)> myconnection; } template<class a, class b> void addlistener(a * app, b & connection) { connection.myconnection.connect( 'i don't know here' ); } } basically, addlistener function won't make connection between signal , function. know don't know i'm doing wrong can't figure out wrong. i'm making helper function can pass functions 1 class call them when they're attached....

i have table that: create table `appointment` ( id int not null auto_increment, user_id int not null, doctor_slot_id int not null, date date not null, primary key(id), foreign key(user_id) references user(id), foreign key(doctor_slot_id) references doctor_slot(id) ); i want user can't arrange appointment doctor more once in day. want add unique constraint between doctor_id , user_id in structure can't. tried things not in sql syntax: unique(user_id, doctor_slot.doctor_id) and unique(user_id, doctor_slot(doctor_id)) and unique(user_id, doctor_id(doctor_slot)) but know, didn't work. there suggestions can make? based on comment doctor_slot is, seem have bit on issue schema design. there should no reason store both slot_id , date in appointment table, in doctor_slot has date component, storing date in appointment table redundant storage of data, , become problematic keep in sync. of course, without date on table impossi...

i have c++ style text file i'm trying pipe gcc remove comments. initially, tried regex approach, had trouble handling things nested comments, string literals , eol issues. so i'm trying like: strip_comments(test_file.c) def strip_comments(text): p = popen(['gcc', '-w', '-e', text], stdin=pipe, stdout=pipe, stderr=stdout) p.stdin.write(text) p.stdin.close() print p.stdout.read() but instead of passing file, i'd pipe contents because files i'm trying preprocess don't have .c extension has had success this? this 1 works subprocess.pipe (os.popen() deprecated), , need pass , additional - argument gcc make process stdin: import os subprocess import popen, pipe def strip_comments(text): p = popen(['gcc', '-fpreprocessed', '-dd', '-e', '-x', 'c++', '-'], stdin=pipe, stdout=pipe, stderr=pipe) p.stdin.write(text) p.stdin.close() ...
