"(CRON) Info (No MTA Installed, Discarding Output)" Error In The Syslog

Answer : Linux uses mail for sending notifications to the user. Most Linux distributions have a mail service including an MTA (Mail Transfer Agent) installed. Ubuntu doesn't though. You can install a mail service, postfix for example, to solve this problem. sudo apt-get install postfix Or you can ignore it. I don't think the inability of cron to send messages has anything to do with the CPU spike (that's linked to the underlying job that cron is running). It might be safest to install an MTA and then read through the messages ( mutt is a good system mail reader). This happens because your cron jobs are producing output and then the cron daemon tries to email that output to you (i.e. root). If you don't need that output, the easiest way to solve this is to discard it at the crontab: sudo crontab -e and add >/dev/null 2>&1 to every job: * * * * * yourCommand >/dev/null 2>&1 In my case, the message was hinting at a permissions problem with the bash

Alternate Output Format For Psql

Answer : I just needed to spend more time staring at the documentation. This command: \x on will do exactly what I wanted. Here is some sample output: select * from dda where u_id=24 and dda_is_deleted='f'; -[ RECORD 1 ]------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- dda_id | 1121 u_id | 24 ab_id | 10304 dda_type | CHECKING dda_status | PENDING_VERIFICATION dda_is_deleted | f dda_verify_op_id | 44938 version | 2 created | 2012-03-06 21:37:50.585845 modified | 2012-03-06 21:37:50.593425 c_id | dda_nickname | dda_account_name | cu_id | 1 abd_id | (New) Expanded Auto Mode: \x auto New for Postgresql 9.2; PSQL automatically fits records to the width of the scr

Css Text-justify Example

The text-justify CSS property sets what type of justification should be applied to text when text-align : justify; is set on an element. text-justify : none ; text-justify : auto ; text-justify : inter-word ; text-justify : inter-character ; text-justify : distribute ; /* Deprecated value */ Syntax The text-justify property is specified as a single keyword chosen from the list of values below. Values none The text justification is turned off. This has the same effect as not setting text-align at all, although it is useful if you need to turn justification on and off for some reason. auto The browser chooses the best type of justification for the current situation based on a balance between performance and quality, but also on what is most appropriate for the language of the text (e.g., English, CJK languages, etc.). This is the default justification used if text-justify is not set at all. inter-word The text is justified by adding space between words (effectively

Access Parent Window From Iframe (cross-domain)

Answer : If I were you I would check out window.postMessage. It may do what you want: For reference see the following: MDN - Window.postMessage https://stackoverflow.com/a/3076648/296889 - see the Window.postMessage section If I understand correctly, all modern browsers do now allow to do this. So I'm here to find the best solution. This is your solution. What you're asking is not possible. See related questions: How to access parent Iframe from JavaScript <iframe> javascript access parent DOM across domains? Cross-domain access in iframe from child to parent EDIT As mentioned in the comments below, @JeremysAwesome's answer offers a method that would allow cross-domain requests under certain circumstances. See the SO question below for more information. Ways to circumvent the same-origin policy but you can change the src attribute of the iframe (adding a #hashtag for example) and listen to the onhashchange event in the child window

Concatenate Several Np Arrays In Python

Answer : concatenate can accept a sequence of array-likes, such as args : In [11]: args = (x1, x2, x3) In [12]: xt = np.concatenate(args) In [13]: xt Out[13]: array([1, 0, 1, 0, 0, 1, 1, 1, 1]) By the way, although axis=1 works, the inputs are all 1-dimensional arrays (so they only have a 0-axis). So it makes more sense to use axis=0 or omit axis entirely since the default is axis=0 .

Can't Reset MySQL (MariaDB) Root Password

Answer : I have found a solution that is as strange as the problem itself. Reboot MySQL/MariaDB using --skip-grant-tables (search for tutorials on the web). (not necessary at all, read my edits at the end of the post) Look at the plugin field into the mysql.user table: MariaDB [mysql]> SELECT user, plugin FROM user; +------+-------------+ | user | plugin | +------+-------------+ | root | unix_socket | | root | unix_socket | | root | unix_socket | | root | unix_socket | +------+-------------+ I had to reset the plugin field of each entry to a blank string. UPDATE user SET plugin=""; // without WHERE clause Also, make sure that a password is defined, because sometimes it seems to be erased (select on user, password fields). If not, update it with: UPDATE user SET password=PASSWORD("my_password") WHERE user="root"; Privileges parameters need to be saved explicitly: FLUSH PRIVILEGES; Then, restart MySQL in normal mode and

Boxplot Of Multiple Columns Of A Pandas Dataframe On The Same Figure (seaborn)

Image
Answer : The seaborn equivalent of df.boxplot() is sns.boxplot(x="variable", y="value", data=pd.melt(df)) Complete example: import numpy as np; np.random.seed(42) import pandas as pd import matplotlib.pyplot as plt import seaborn as sns df = pd.DataFrame(data = np.random.random(size=(4,4)), columns = ['A','B','C','D']) sns.boxplot(x="variable", y="value", data=pd.melt(df)) plt.show() This works because pd.melt converts a wide-form dataframe A B C D 0 0.374540 0.950714 0.731994 0.598658 1 0.156019 0.155995 0.058084 0.866176 2 0.601115 0.708073 0.020584 0.969910 3 0.832443 0.212339 0.181825 0.183405 to long-form variable value 0 A 0.374540 1 A 0.156019 2 A 0.601115 3 A 0.832443 4 B 0.950714 5 B 0.155995 6 B 0.708073 7 B 0.212339 8 C 0.731994 9 C

A Long Bigger Than Long.MAX_VALUE

Answer : That method can't return true . That's the point of Long.MAX_VALUE . It would be really confusing if its name were... false. Then it should be just called Long.SOME_FAIRLY_LARGE_VALUE and have literally zero reasonable uses. Just use Android's isUserAGoat , or you may roll your own function that always returns false . Note that a long in memory takes a fixed number of bytes. From Oracle: long: The long data type is a 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). Use this data type when you need a range of values wider than those provided by int. As you may know from basic computer science or discrete math, there are 2^64 possible values for a long, since it is 64 bits. And as you know from discrete math or number theory or common sense, if there's only finitely many possibilities, one of them has to be the largest. That would

3d Array Javascript Code Example

Example 1: how to declare 3d array in javascript var myArray = [ [ [ ] ] ] ; Example 2: javascript define multidimensional array var iMax = 20 ; var jMax = 10 ; var f = new Array ( ) ; for ( i = 0 ; i < iMax ; i ++ ) { f [ i ] = new Array ( ) ; for ( j = 0 ; j < jMax ; j ++ ) { f [ i ] [ j ] = 0 ; } } Example 3: multi-dimensional array js var array = [ [ "0, 0" , "1, 0" , "2, 0" , "3, 0" , "4, 0" ] , [ "0, 1" , "1, 1" , "2, 1" , "3, 1" , "4, 1" ] , [ "0, 2" , "1, 2" , "2, 2" , "3, 2" , "4, 2" ] , [ "0, 3" , "1, 3" , "2, 3" , "3, 3" , "4, 3" ] , [ "0, 4" , "1, 4" , "2, 4" , "3, 4" , "4, 4" ] , ] ; // Think of it as coordinates, array[x, y] x = 0; y = 0; is "0,

Couldn't Load Memtrack Module Logcat Error

Answer : This error, as you can read on the question linked in comments above, results to be: "[...] a problem with loading {some} hardware module. This could be something to do with GPU support, sdcard handling, basically anything." The step 1 below should resolve this problem. Also as I can see, you have some strange package names inside your manifest: package="com.example.hive" in <manifest> tag, android:name="com.sit.gems.app.GemsApplication" for <application> and android:name="com.sit.gems.activity" in <activity> As you know, these things do not prevent your app to be displayed. But I think: the Couldn't load memtrack module error could occur because of emulators configurations problems and, because your project contains many organization problems, it might help to give a fresh redesign. For better using and with few things, this can be resolved by following these tips: 1. Try an other emulator... And even
