how comma operator work in c++? for instance, if do: a = b, c; does end equaling b or c? (yes, know easy test - documenting on here find answer quickly.) update: question has exposed nuance when using comma operator. document this: a = b, c; // set value of b! = (b, c); // set value of c! this question inspired typo in code. intended be a = b; c = d; turned into a = b, // <- note comma typo! c = d; it equal b. the comma operator has lower precedence assignment.

here want do, histogram plots of columns of dataframe without grid axes. below code works, preferably i'd more elegant solution (such passing argument hist) %matplotlib inline import numpy np import pandas pd import matplotlib.pyplot plt x = np.asarray([50]*25+[30]*10) x2 = np.asarray([90]*10+[20]*25) x3 = np.asarray([10]*15+[70]*20) df = pd.dataframe(np.vstack([x, x2, x3]).t) def plot_hists(df, nbins=10, figsize=(8, 8), disable_axis_labels = true): plt.close('all') grid_of_ax_hists = df.hist(bins=nbins, figsize=figsize) if disable_axis_labels: row in grid_of_ax_hists: ax in row: ax.xaxis.set_visible(false) ax.yaxis.set_visible(false) plt.show() df.hist() plt.subplots() plot_hists(df, nbins=10, figsize=(8, 8), disable_axis_labels = true) even thread kinda old, i'd add working solution because i've had same issue. at least in pandas 0.18 df.hist() takes possible plot...

i have program communicates docker dameon remotely using rest api. receives information images, containers, repositories in json format. want translate rest api output json format c++ structures. json format takes form of key, value pair key string, value string, number, array, etc. i know if there standard schema definition docker json objects? thanks. first of all, there's official remote api documentation . however, since contains "only" example requests , no authoritative schema definitions, it's not you're looking for. there not seem be official json schema docker remote api. however, api responses directly generated corresponding go structs can find in single file in source code repository . for example, consider definition of container response type: // "/containers/json" type port struct { ip string privateport int publicport int type string } type container struct { id s...

i using jump server (bastion) connect private ec2 instance. connection successful, not able scp jar file private ec2 instance jump server location. command: [ec2-user@ip-xxx-xx-xx-x3 ~]$ scp x.jar ec2-user@xx.xxx .xx.xx5:/home/user result: "ssh: connect host xx.xxx.xx.xx5 port 22: connection timed out would highly appreciate input/suggestions fix this. do security group rules allow traffic bastion private instance, or bastion private? assume description you're copying private bastion? if rules 1 way have tried running reverse scp. so: scp ec2-user@ip-xxx:/path/to/file.jar ./file.jar

i have function foo makes ajax request. how can return response foo ? i tried return value success callback assigning response local variable inside function , return one, none of ways return response. function foo() { var result; $.ajax({ url: '...', success: function(response) { result = response; // return response; // <- tried 1 } }); return result; } var result = foo(); // ends being `undefined`. -> more general explanation of async behavior different examples, please see why variable unaltered after modify inside of function? - asynchronous code reference -> if understand problem, skip possible solutions below. the problem the a in ajax stands asynchronous . means sending request (or rather receiving response) taken out of normal execution flow. in example, $.ajax returns , next statement, return result; , executed before function passed success callback ca...
