You'll find the junit launch commands in .metadata/.plugins/org.eclipse.debug.core/.launches, assuming your Eclipse works like mine does. The files are named {TestClass}.launch.
You will probably also need the .classpath file in the project directory that contains the test class.
Like the run configurations, they're XML files (even if they don't have an xml extension).
The link you gave does actually describe the differences, but it's buried at the bottom of the page:

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.
The conversion could be to normalize \r\n
to \n
(or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.
Problems only surface when I am I trying to give the first loaded content an active state
Does this mean that you want to add a class to the first button?
$('.o-links').click(function(e) { // ... }).first().addClass('O_Nav_Current');
instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:
CSS:
.image-area { width: 100%; height: auto; display: none; } .image-area:first-of-type { display: block; }
JavaScript:
var $slides = $('.image-area'), $btns = $('a.o-links'); $btns.on('click', function (e) { var i = $btns.removeClass('O_Nav_Current').index(this); $(this).addClass('O_Nav_Current'); $slides.filter(':visible').fadeOut(1000, function () { $slides.eq(i).fadeIn(1000); }); e.preventDefault(); }).first().addClass('O_Nav_Current');
Seeing that it appears you are running using the SQL syntax, try with the correct wild card.
SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4;
If you aren't using fetchBusinesses method anywhere apart from the effect, you could simply move it into the effect and avoid the warning
useEffect(() => {
const fetchBusinesses = () => {
return fetch("theURL", {method: "GET"}
)
.then(res => normalizeResponseErrors(res))
.then(res => {
return res.json();
})
.then(rcvdBusinesses => {
// some stuff
})
.catch(err => {
// some error handling
});
};
fetchBusinesses();
}, []);
If however you are using fetchBusinesses outside of render, you must note two things
fetchBusinesses
as a method when it's used during mount with its enclosing closure?To sum it up I would say that if you are using fetchBusinesses
outside of useEffect
you can disable the rule using // eslint-disable-next-line react-hooks/exhaustive-deps
otherwise you can move the method inside of useEffect
To disable the rule you would write it like
useEffect(() => {
// other code
...
// eslint-disable-next-line react-hooks/exhaustive-deps
}, [])
As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.
For example:
Assume we have double _bmi;
and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:
String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}
or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.
I was upgrading tensorflow to 1.4.0 & was hitting my head on wall as this error was not solving, but finally solved it. Guess what?
One of my python script was running, and it was using tensorflow . Package installed successfully after closing it.
Perhaps the error message is somewhat misleading, but the gist is that X_train
is a list, not a numpy array. You cannot use array indexing on it. Make it an array first:
out_images = np.array(X_train)[indices.astype(int)]

After running these two commands, you must run the first command again so that the index does not go again into read-only mode
All of the above answer are correct but they did not work for me. The only way I was able to make this work was by follow steps/commands:
npm uninstall -g @angular/[email protected]
npm cache clean --force
npm install -g @angular/cli@latest
npm install node-sass -g
ng new MY_PROJECT_NAME
cp -r from_my_old_project to_new_MY_PROJECT_NAME
try use keyup.enter or keydown.enter

Entity Framework Core does not support multiple parallel operations being run on the same DbContext
instance. This includes both parallel execution of async
queries and any explicit concurrent use from multiple threads. Therefore, always await async
calls immediately, or use separate DbContext
instances for operations that execute in parallel.
Run ./gradlew build -stacktrace
in Android Studio terminal. It helps you to find a file that causes this error.
I encountered the same problem with:
Spring Boot version = 1.5.10
Spring Security version = 4.2.4
The problem occurred on the endpoints, where the ModelAndView
viewName was defined with a preceding forward slash. Example:
ModelAndView mav = new ModelAndView("/your-view-here");
If I removed the slash it worked fine. Example:
ModelAndView mav = new ModelAndView("your-view-here");
I also did some tests with RedirectView and it seemed to work with a preceding forward slash.
I had the same issue, I could solve it by switching fom JDK 11 to JDK 8.

By setting verbose 0, 1 or 2 you just say how do you want to 'see' the training progress for each epoch.
verbose=0
will show you nothing (silent)
verbose=1
will show you an animated progress bar like this:
verbose=2
will just mention the number of epoch like this:
The results = 'hide'
option doesn't prevent other messages to be printed.
To hide them, the following options are useful:
{r, error=FALSE}
{r, warning=FALSE}
{r, message=FALSE}
In every case, the corresponding warning, error or message will be printed to the console instead.
you can use skimage.img_as_ubyte(yourdata)
it will make you numpy array ranges from 0->255
from skimage import img_as_ubyte
img = img_as_ubyte(data)
cv2.imshow("Window", img)
In general, to set a video's FPS to 24, almost always you can do:
With Audio and without re-encoding:
# Extract video stream
ffmpeg -y -i input_video.mp4 -c copy -f h264 output_raw_bitstream.h264
# Extract audio stream
ffmpeg -y -i input_video.mp4 -vn -acodec copy output_audio.aac
# Remux with new FPS
ffmpeg -y -r 24 -i output_raw_bitstream.h264 -i output-audio.aac -c copy output.mp4
If you want to find the video format (H264 in this case), you can use FFprobe, like this
ffprobe -loglevel error -select_streams v -show_entries stream=codec_name -of default=nw=1:nk=1 input_video.mp4
which will output:
h264
Read more in How can I analyze file and detect if the file is in H.264 video format?
With re-encoding:
ffmpeg -y -i input_video.mp4 -vf -r 24 output.mp4
You can add parameter columns or use dict
with key which is converted to column name:
np.random.seed(123)
e = np.random.normal(size=10)
dataframe=pd.DataFrame(e, columns=['a'])
print (dataframe)
a

I had similar situation. I found that one of my config maps was duplicated. I had two configmaps for the same namespace. One had the correct namespace reference, the other was pointing to the wrong namespace.
I deleted and recreated the configmap with the correct file (or fixed file). I am only using one, and that seemed to make the particular cluster happier.
So I would check the files for any typos or duplicate items that could be causing conflict.
If you want to change the default container and you are using Virtualbox, you can do it via the commandline / CLI:
docker-machine stop
VBoxManage modifyvm default --cpus 2
VBoxManage modifyvm default --memory 4096
docker-machine start
I had the same problem. Docker running but couldn't access it through CLI.
For me the problem was solved by executing "Docker Quickstart Terminal.app". This is located in the "/Applications/Docker/" folder. As long as I work in this instance of the Terminal app Docker works perfectly. If a second window is needed I have to run the "Quickstart" app once more.
I have a Docker for Mac installation. Therefore I am not sure if my solution is valid for a Homebrew installation.
The "Docker Quickstart Terminal" app seems to be essentially some applescripts to launch the terminal app and a bash start script that initialise all the necessary environment variables.
Hope this helps someone else !
After a few hours of messing around I eventually got something that works, partially answered in a similar issue here: How do I include a JavaScript file in another JavaScript file?
BUT there was an import that was screwing the rest of it up:
.vue
files<script>
var mylib = require('./mylib');
export default {
....
mylib
exports.myfunc = () => {....}
import
The actual issue in my case (which I didn't think was relevant!) was that mylib.js
was itself using other dependencies. The resulting error seems to have nothing to do with this, and there was no transpiling error from webpack
but anyway I had:
import models from './model/models'
import axios from 'axios'
This works so long as I'm not using mylib
in a .vue
component. However as soon as I use mylib
there, the error described in this issue arises.
I changed to:
let models = require('./model/models');
let axios = require('axios');
And all works as expected.
The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.
In android Oreo,notification app is done by using channels and NotificationHelper class.It should have a channel id and channel name.
First u have to create a NotificationHelper Class
public class NotificationHelper extends ContextWrapper {
private static final String EDMT_CHANNEL_ID="com.example.safna.notifier1.EDMTDEV";
private static final String EDMT_CHANNEL_NAME="EDMTDEV Channel";
private NotificationManager manager;
public NotificationHelper(Context base)
{
super(base);
createChannels();
}
private void createChannels()
{
NotificationChannel edmtChannel=new NotificationChannel(EDMT_CHANNEL_ID,EDMT_CHANNEL_NAME,NotificationManager.IMPORTANCE_DEFAULT);
edmtChannel.enableLights(true);
edmtChannel.enableVibration(true);
edmtChannel.setLightColor(Color.GREEN);
edmtChannel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
getManager().createNotificationChannel(edmtChannel);
}
public NotificationManager getManager()
{
if (manager==null)
manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
return manager;
}
public NotificationCompat.Builder getEDMTChannelNotification(String title,String body)
{
return new NotificationCompat.Builder(getApplicationContext(),EDMT_CHANNEL_ID)
.setContentText(body)
.setContentTitle(title)
.setSmallIcon(R.mipmap.ic_launcher_round)
.setAutoCancel(true);
}
}
Create a button in activity xml file,then In the main activity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
helper=new NotificationHelper(this);
btnSend=(Button)findViewById(R.id.btnSend);
btnSend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String title="Title";
String content="Content";
Notification.Builder builder=helper.getEDMTChannelNotification(title,content);
helper.getManager().notify(new Random().nextInt(),builder.build());
}
});
}
Then run ur project
A temporary table can have 3 kinds, the #
is the most used. This is a temp table that only exists in the current session.
An equivalent of this is @
, a declared table variable. This has a little less "functions" (like indexes etc) and is also only used for the current session.
The ##
is one that is the same as the #
, however, the scope is wider, so you can use it within the same session, within other stored procedures.
You can create a temp table in various ways:
declare @table table (id int)
create table #table (id int)
create table ##table (id int)
select * into #table from xyz
Saving a Keras model:
model = ... # Get model (Sequential, Functional Model, or Model subclass)
model.save('path/to/location')
Loading the model back:
from tensorflow import keras
model = keras.models.load_model('path/to/location')
For more information, read Documentation
Popen expect a list of strings for non-shell calls and a string for shell calls.
Call subprocess.Popen with shell=True:
process = subprocess.Popen(command, stdout=tempFile, shell=True)
Hopefully this solves your issue.
This issue is listed here: https://bugs.python.org/issue17023
Had the same issue after updating to Android Studio 2.3, the fix was to add the following package in the build.gradle
:
compile 'com.android.support:support-v13:25.3.1'
Note: Change the version to match other support library packages used in your project
In my case I console.log(this.$route)
and returned the fullPath:
console.js:
fullPath: "/solicitud/MX/666",
params: {market: "MX", id: "666"},
path: "/solicitud/MX/666"
console.js: /solicitud/MX/666
What did you expect the following to do?
v1 = [0,0],[M[i,0],M[i,1]]
v1 = [M[i,0]],[M[i,1]]
This is making two different tuples, and you overwrite what you did the first time... Anyway, matplotlib
does not understand what a "vector" is in the sense you are using. You have to be explicit, and plot "arrows":
In [5]: ax = plt.axes()
In [6]: ax.arrow(0, 0, *v1, head_width=0.05, head_length=0.1)
Out[6]: <matplotlib.patches.FancyArrow at 0x114fc8358>
In [7]: ax.arrow(0, 0, *v2, head_width=0.05, head_length=0.1)
Out[7]: <matplotlib.patches.FancyArrow at 0x115bb1470>
In [8]: plt.ylim(-5,5)
Out[8]: (-5, 5)
In [9]: plt.xlim(-5,5)
Out[9]: (-5, 5)
In [10]: plt.show()
Result:
You can use this VSCode Extension called Reload
You can use the Web API FontFace constructor (also Typescript) without need of CSS:
export async function loadFont(fontFamily: string, url: string): Promise<void> {
const font = new FontFace(fontFamily, `local(${fontFamily}), url(${url})`);
// wait for font to be loaded
await font.load();
// add font to document
document.fonts.add(font);
// enable font with CSS class
document.body.classList.add("fonts-loaded");
}
import ComicSans from "./assets/fonts/ComicSans.ttf";
loadFont("Comic Sans ", ComicSans).catch((e) => {
console.log(e);
});
Declare a file font.ts
with your modules (TS only):
declare module "*.ttf";
declare module "*.woff";
declare module "*.woff2";
If TS cannot find FontFace type as its still officially WIP, add this declaration to your project. It will work in your browser, except for IE.
Try rerunning the pod and running
kubectl get pods --watch
to watch the status of the pod as it progresses.
In my case, I would only see the end result, 'CrashLoopBackOff,' but the docker container ran fine locally. So I watched the pods using the above command, and I saw the container briefly progress into an OOMKilled state, which meant to me that it required more memory.
You were looking for help on installations with pip. You can find it with the following command:
pip install --help
Running pip install -e /path/to/package
installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.
There is another way to install the pip3: just reinstall 3.6.
For me, in Ubuntu 18.04. I needed to chown inside ~/.config/composer/
E.g.
sudo chown -R $USER ~/.config/composer
Then global commands work.
Starting with node 8.0.0, you can use this:
const fs = require('fs');
const util = require('util');
const readdir = util.promisify(fs.readdir);
async function myF() {
let names;
try {
names = await readdir('path/to/dir');
} catch (err) {
console.log(err);
}
if (names === undefined) {
console.log('undefined');
} else {
console.log('First Name', names[0]);
}
}
myF();

If you want to change the external terminal to the new windows terminal, here's how.
image
has a shape of (64,64,3)
.
Your input placeholder _x
have a shape of (?, 64,64,3)
.
The problem is that you're feeding the placeholder with a value of a different shape.
You have to feed it with a value of (1, 64, 64, 3)
= a batch of 1 image.
Just reshape your image
value to a batch with size one.
image = array(img).reshape(1, 64,64,3)
P.S: the fact that the input placeholder accepts a batch of images, means that you can run predicions for a batch of images in parallel.
You can try to read more than 1 image (N images) and than build a batch of N image, using a tensor with shape (N, 64,64,3)

Using ngcWebpack Plugin I got this error when not specifying a mainPath or entryModule.
In swift 3 use this -
object?.addTarget(objectWhichHasMethod, action: #selector(classWhichHasMethod.yourMethod), for: someUIControlEvents)
For example(from my code) -
self.datePicker?.addTarget(self, action:#selector(InfoTableViewCell.datePickerValueChanged), for: .valueChanged)
Just give a :
after method name if you want the sender as parameter.
By converting the matrix to array by using
n12 = np.squeeze(np.asarray(n2))
X12 = np.squeeze(np.asarray(x1))
solved the issue.

With Angular CLI 6 you need to use builders as ng eject is deprecated and will soon be removed in 8.0. That's what it says when I try to do an ng eject
You can use angular-builders package (https://github.com/meltedspark/angular-builders) to provide your custom webpack config.
I have tried to summarize all in a single blog post on my blog - How to customize build configuration with custom webpack config in Angular CLI 6
but essentially you add following dependencies -
"devDependencies": {
"@angular-builders/custom-webpack": "^7.0.0",
"@angular-builders/dev-server": "^7.0.0",
"@angular-devkit/build-angular": "~0.11.0",
In angular.json make following changes -
"architect": {
"build": {
"builder": "@angular-builders/custom-webpack:browser",
"options": {
"customWebpackConfig": {"path": "./custom-webpack.config.js"},
Notice change in builder and new option customWebpackConfig. Also change
"serve": {
"builder": "@angular-builders/dev-server:generic",
Notice the change in builder again for serve target. Post these changes you can create a file called custom-webpack.config.js in your same root directory and add your webpack config there.
However, unlike ng eject configuration provided here will be merged with default config so just add stuff you want to edit/add.
const absolutePath = path.join(__dirname, some, dir);
vs.
const absolutePath = path.resolve(__dirname, some, dir);
path.join
will concatenate __dirname
which is the directory name of the current file concatenated with values of some
and dir
with platform-specific separator.
Whereas
path.resolve
will process __dirname
, some
and dir
i.e. from right to left prepending it by processing it.
If any of the values of some
or dir
corresponds to a root path then the previous path will be omitted and process rest by considering it as root
In order to better understand the concept let me explain both a little bit more detail as follows:-
The path.join
and path.resolve
are two different methods or functions of the path module provided by nodejs.
Where both accept a list of paths but the difference comes in the result i.e. how they process these paths.
path.join
concatenates all given path segments together using the platform-specific separator as a delimiter, then normalizes the resulting path. While the path.resolve()
process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.
When no arguments supplied
The following example will help you to clearly understand both concepts:-
My filename is index.js
and the current working directory is E:\MyFolder\Pjtz\node
const path = require('path');
console.log("path.join() : ", path.join());
// outputs .
console.log("path.resolve() : ", path.resolve());
// outputs current directory or equivalent to __dirname
Result
? node index.js
path.join() : .
path.resolve() : E:\MyFolder\Pjtz\node
path.resolve()
method will output the absolute path whereas the path.join()
returns . representing the current working directory if nothing is provided
When some root path is passed as arguments
const path=require('path');
console.log("path.join() : " ,path.join('abc','/bcd'));
console.log("path.resolve() : ",path.resolve('abc','/bcd'));
Result i
? node index.js
path.join() : abc\bcd
path.resolve() : E:\bcd
path.join()
only concatenates the input list with platform-specific separator while the path.resolve()
process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.
When you normalize a matrix using NORM_L1, you are dividing every pixel value by the sum of absolute values of all the pixels in the image. As a result, all pixel values become much less than 1 and you get a black image. Try NORM_MINMAX instead of NORM_L1.
Despite the plethora of wrong answers here that attempt to circumvent the error by numerically manipulating the predictions, the root cause of your error is a theoretical and not computational issue: you are trying to use a classification metric (accuracy) in a regression (i.e. numeric prediction) model (LinearRegression
), which is meaningless.
Just like the majority of performance metrics, accuracy compares apples to apples (i.e true labels of 0/1 with predictions again of 0/1); so, when you ask the function to compare binary true labels (apples) with continuous predictions (oranges), you get an expected error, where the message tells you exactly what the problem is from a computational point of view:
Classification metrics can't handle a mix of binary and continuous target
Despite that the message doesn't tell you directly that you are trying to compute a metric that is invalid for your problem (and we shouldn't actually expect it to go that far), it is certainly a good thing that scikit-learn at least gives you a direct and explicit warning that you are attempting something wrong; this is not necessarily the case with other frameworks - see for example the behavior of Keras in a very similar situation, where you get no warning at all, and one just ends up complaining for low "accuracy" in a regression setting...
I am super-surprised with all the other answers here (including the accepted & highly upvoted one) effectively suggesting to manipulate the predictions in order to simply get rid of the error; it's true that, once we end up with a set of numbers, we can certainly start mingling with them in various ways (rounding, thresholding etc) in order to make our code behave, but this of course does not mean that our numeric manipulations are meaningful in the specific context of the ML problem we are trying to solve.
So, to wrap up: the problem is that you are applying a metric (accuracy) that is inappropriate for your model (LinearRegression
): if you are in a classification setting, you should change your model (e.g. use LogisticRegression
instead); if you are in a regression (i.e. numeric prediction) setting, you should change the metric. Check the list of metrics available in scikit-learn, where you can confirm that accuracy is used only in classification.
Compare also the situation with a recent SO question, where the OP is trying to get the accuracy of a list of models:
models = []
models.append(('SVM', svm.SVC()))
models.append(('LR', LogisticRegression()))
models.append(('LDA', LinearDiscriminantAnalysis()))
models.append(('KNN', KNeighborsClassifier()))

where the first 6 models work OK, while all the rest (commented-out) ones give the same error. By now, you should be able to convince yourself that all the commented-out models are regression (and not classification) ones, hence the justified error.
A last important note: it may sound legitimate for someone to claim:
OK, but I want to use linear regression and then just round/threshold the outputs, effectively treating the predictions as "probabilities" and thus converting the model into a classifier
Actually, this has already been suggested in several other answers here, implicitly or not; again, this is an invalid approach (and the fact that you have negative predictions should have already alerted you that they cannot be interpreted as probabilities). Andrew Ng, in his popular Machine Learning course at Coursera, explains why this is a bad idea - see his Lecture 6.1 - Logistic Regression | Classification at Youtube (explanation starts at ~ 3:00), as well as section 4.2 Why Not Linear Regression [for classification]? of the (highly recommended and freely available) textbook An Introduction to Statistical Learning by Hastie, Tibshirani and coworkers...
I had the same problem today and have gone through the following path - (%USERPROFILE%\AppData\Roaming\npm) and came to know that there is some junk data and when I cleared everything under npm directory. Now when I ran (npm install command again). Now everything works fine.
Alternatively you can write the same like
{
test: /\.(svg|png|jpg|jpeg|gif)$/,
include: 'path of input image directory',
use: {
loader: 'file-loader',
options: {
name: '[path][name].[ext]',
outputPath: 'path of output image directory'
}
}
}
and then use simple import
import varName from 'relative path';
and in jsx write like
<img src={varName} ..../>
....
are for other image attributes
You could use tf.config.set_visible_devices
. One possible function that allows you to set if and which GPUs to use is:
import tensorflow as tf
def set_gpu(gpu_ids_list):
gpus = tf.config.list_physical_devices('GPU')
if gpus:
try:
gpus_used = [gpus[i] for i in gpu_ids_list]
tf.config.set_visible_devices(gpus_used, 'GPU')
logical_gpus = tf.config.experimental.list_logical_devices('GPU')
print(len(gpus), "Physical GPUs,", len(logical_gpus), "Logical GPU")
except RuntimeError as e:
# Visible devices must be set before GPUs have been initialized
print(e)
Suppose you are on a system with 4 GPUs and you want to use only two GPUs, the one with id = 0
and the one with id = 2
, then the first command of your code, immediately after importing the libraries, would be:
set_gpu([0, 2])
In your case, to use only the CPU, you can invoke the function with an empty list:
set_gpu([])
For completeness, if you want to avoid that the runtime initialization will allocate all memory on the device, you can use tf.config.experimental.set_memory_growth
.
Finally, the function to manage which devices to use, occupying the GPUs memory dynamically, becomes:
import tensorflow as tf
def set_gpu(gpu_ids_list):
gpus = tf.config.list_physical_devices('GPU')
if gpus:
try:
gpus_used = [gpus[i] for i in gpu_ids_list]
tf.config.set_visible_devices(gpus_used, 'GPU')
for gpu in gpus_used:
tf.config.experimental.set_memory_growth(gpu, True)
logical_gpus = tf.config.experimental.list_logical_devices('GPU')
print(len(gpus), "Physical GPUs,", len(logical_gpus), "Logical GPU")
except RuntimeError as e:
# Visible devices must be set before GPUs have been initialized
print(e)

One of the fundamental principles behind a promise is that it's handled asynchronously. This means that you cannot create a promise and then immediately use its result synchronously in your code (e.g. it's not possible to return the result of a promise from within the function that initiated the promise).
What you likely want to do instead is to return the entire promise itself. Then whatever function needs its result can call .then()
on the promise, and the result will be there when the promise has been resolved.
Here is a resource from HTML5Rocks that goes over the lifecycle of a promise, and how its output is resolved asynchronously:
http://www.html5rocks.com/en/tutorials/es6/promises/
The .spec.ts files are for unit tests for individual components.

Deleting node_modules folder contents and running

solved the problem for me!
Here is one way to do it, in case it is still useful: I ran this in pyspark shell, Python version 2.7.12 and my Spark install was version 2.0.1.
PS: I guess you meant to use different seeds for the df_1 df_2 and the code below reflects that.
from pyspark.sql.types import FloatType
from pyspark.sql.functions import randn, rand
import pyspark.sql.functions as F
df_1 = sqlContext.range(0, 10)
df_2 = sqlContext.range(11, 20)
df_1 = df_1.select("id", rand(seed=10).alias("uniform"), randn(seed=27).alias("normal"))
df_2 = df_2.select("id", rand(seed=11).alias("uniform"), randn(seed=28).alias("normal_2"))
def get_uniform(df1_uniform, df2_uniform):
if df1_uniform:
return df1_uniform
if df2_uniform:
return df2_uniform
u_get_uniform = F.udf(get_uniform, FloatType())
df_3 = df_1.join(df_2, on = "id", how = 'outer').select("id", u_get_uniform(df_1["uniform"], df_2["uniform"]).alias("uniform"), "normal", "normal_2").orderBy(F.col("id"))
Here are the outputs I get:

I've just edited QoP's current answer to support SSR and use it with Next.js (React 16.8.0+):
/hooks/useWindowDimensions.js:
import { useState, useEffect } from 'react';
export default function useWindowDimensions() {
const hasWindow = typeof window !== 'undefined';
function getWindowDimensions() {
const width = hasWindow ? window.innerWidth : null;
const height = hasWindow ? window.innerHeight : null;
return {
width,
height,
};
}
const [windowDimensions, setWindowDimensions] = useState(getWindowDimensions());
useEffect(() => {
if (hasWindow) {
function handleResize() {
setWindowDimensions(getWindowDimensions());
}
window.addEventListener('resize', handleResize);
return () => window.removeEventListener('resize', handleResize);
}
}, [hasWindow]);
return windowDimensions;
}
/yourComponent.js:
import useWindowDimensions from './hooks/useWindowDimensions';
const Component = () => {
const { height, width } = useWindowDimensions();
/* you can also use default values or alias to use only one prop: */
// const { height: windowHeight = 480 } useWindowDimensions();
return (
<div>
width: {width} ~ height: {height}
</div>
);
}
It is 2019 and many of the answers here would work, depending on what you want to do. If you want to pass in some internal state not visible in URL (params, query) you can use state
since 7.2 (as I have learned just today :) ).
From the blog (credits Tomasz Kula) - you navigate to route....
...from ts: this.router.navigateByUrl('/details', { state: { hello: 'world' } });
...from HTML template: <a routerLink="/details" [state]="{ hello: 'world' }">Go</a>
And to pick it up in the target component:
constructor(public activatedRoute: ActivatedRoute) {}
ngOnInit() {
this.state$ = this.activatedRoute.paramMap
.pipe(map(() => window.history.state))
}
Late, but hope this helps someone with recent Angular.
the tutorial of how to build NodeJS for Android https://github.com/dna2github/dna2oslab/tree/master/android/build
there are several versions v0.12, v4, v6, v7
It is easy to run compiled binary on Android; for example run compiled Nginx: https://github.com/dna2github/dna2mtgol/tree/master/fileShare
You just need to modify code to replace Nginx to NodeJS; it is better if using Android Service to run node js server on the backend.

's good answer, here is how I choose among the two in practice:
lateinit
is for external initialisation: when you need external stuff to initialise your value by calling a method.
e.g. by calling:
private lateinit var value: MyClass
fun init(externalProperties: Any) {
value = somethingThatDependsOn(externalProperties)
}
While lazy
is when it only uses dependencies internal to your object.
You can open the PDF file and extract its contents using the Adobe library (which I believe you can download from Adobe as part of the SDK, but it comes with certain versions of Acrobat as well)
Make sure to add the Library to your references too (On my machine it is the Adobe Acrobat 10.0 Type Library, but not sure if that is the newest version)
Even with the Adobe library it is not trivial (you'll need to add your own error-trapping etc):
Function getTextFromPDF(ByVal strFilename As String) As String
Dim objAVDoc As New AcroAVDoc
Dim objPDDoc As New AcroPDDoc
Dim objPage As AcroPDPage
Dim objSelection As AcroPDTextSelect
Dim objHighlight As AcroHiliteList
Dim pageNum As Long
Dim strText As String
strText = ""
If (objAvDoc.Open(strFilename, "") Then
Set objPDDoc = objAVDoc.GetPDDoc
For pageNum = 0 To objPDDoc.GetNumPages() - 1
Set objPage = objPDDoc.AcquirePage(pageNum)
Set objHighlight = New AcroHiliteList
objHighlight.Add 0, 10000 ' Adjust this up if it's not getting all the text on the page
Set objSelection = objPage.CreatePageHilite(objHighlight)
If Not objSelection Is Nothing Then
For tCount = 0 To objSelection.GetNumText - 1
strText = strText & objSelection.GetText(tCount)
Next tCount
End If
Next pageNum
objAVDoc.Close 1
End If
getTextFromPDF = strText
End Function
What this does is essentially the same thing you are trying to do - only using Adobe's own library. It's going through the PDF one page at a time, highlighting all of the text on the page, then dropping it (one text element at a time) into a string.
Keep in mind what you get from this could be full of all kinds of non-printing characters (line feeds, newlines, etc) that could even end up in the middle of what look like contiguous blocks of text, so you may need additional code to clean it up before you can use it.
Hope that helps!
You are right. This is a badly documented issue. But you can change the font size parameter (by opposition to font scale) directly after building the plot. Check the following example:
import seaborn as sns
tips = sns.load_dataset("tips")
b = sns.boxplot(x=tips["total_bill"])
b.axes.set_title("Title",fontsize=50)
b.set_xlabel("X Label",fontsize=30)
b.set_ylabel("Y Label",fontsize=20)
b.tick_params(labelsize=5)
sns.plt.show()
, which results in this:
To make it consistent in between plots I think you just need to make sure the DPI is the same. By the way it' also a possibility to customize a bit the rc dictionaries since "font.size" parameter exists but I'm not too sure how to do that.
NOTE: And also I don't really understand why they changed the name of the font size variables for axis labels and ticks. Seems a bit un-intuitive.
Here is another workaround with refernce to JavierFuentes answer:
<a [routerLink]="['self-route', id]" fragment="some-element" (click)="gotoHashtag('some-element')">Jump to Element</a>
in script:
import {ActivatedRoute} from "@angular/router";
import {Subscription} from "rxjs/Subscription";
export class Links {
private scrollExecuted: boolean = false;
constructor(private route: ActivatedRoute) {}
ngAfterViewChecked() {
if (!this.scrollExecuted) {
let routeFragmentSubscription: Subscription;
routeFragmentSubscription = this.route.fragment.subscribe(fragment => {
if (fragment) {
let element = document.getElementById(fragment);
if (element) {
element.scrollIntoView();
this.scrollExecuted = true;
// Free resources
setTimeout(
() => {
console.log('routeFragmentSubscription unsubscribe');
routeFragmentSubscription.unsubscribe();
}, 0);
}
}
});
}
}
gotoHashtag(fragment: string) {
const element = document.querySelector("#" + fragment);
if (element) element.scrollIntoView(element);
}
}
This allows user to directly scroll to element, if user directly lands on the page having hashtag in url.
But in this case, I have subscribed route Fragment in ngAfterViewChecked
but ngAfterViewChecked()
gets called continuously per every ngDoCheck
and it doesn't allows user to scroll back to top, so routeFragmentSubscription.unsubscribe
is called after a timeout of 0 millis after view is scrolled to element.
Additionally gotoHashtag
method is defined to scroll to element when user specifically clicks on the anchor tag.
Update:
If url has querystrings, [routerLink]="['self-route', id]"
in anchor wont preserve the querystrings. I tried following workaround for the same:
<a (click)="gotoHashtag('some-element')">Jump to Element</a>
constructor( private route: ActivatedRoute,
private _router:Router) {
}
...
...
gotoHashtag(fragment: string) {
let url = '';
let urlWithSegments = this._router.url.split('#');
if(urlWithSegments.length){
url = urlWithSegments[0];
}
window.location.hash = fragment;
const element = document.querySelector("#" + fragment);
if (element) element.scrollIntoView(element);
}
On top of @unutbu answer, you could coerce pandas numpy object array to native (float64) type, something along the line
import pandas as pd
pd.to_numeric(df['tester'], errors='coerce')
Specify errors='coerce' to force strings that can't be parsed to a numeric value to become NaN. Column type would be dtype: float64
, and then isnan
check should work

You can try, (filtering with 1 object like a list or a set of values)
ds = ds.filter(functions.col(COL_NAME).isin(myList));
or as @Tony Fraser suggested, you can try, (with a Seq of objects)
ds = ds.filter(functions.col(COL_NAME).isin(mySeq));
All the answers are correct but most of them do not represent a good coding style. Also, you should always consider the variable length of arguments for the future, even though they are static at a certain point in time.
The short answer taken from the announcement of jQuery 3.0 Final Release :
Along with the regular version of jQuery that includes the ajax and effects modules, we’re releasing a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code.
The file size (gzipped) is about 6k smaller, 23.6k vs 30k.
The dict.items
iterates over the key-value pairs of a dictionary. Therefore for key, value in dictionary.items()
will loop over each pair. This is documented information and you can check it out in the official web page, or even easier, open a python console and type help(dict.items)
. And now, just as an example:
>>> d = {'hello': 34, 'world': 2999}
>>> for key, value in d.items():
... print key, value
...
world 2999
hello 34
The AttributeError
is an exception thrown when an object does not have the attribute you tried to access. The class dict
does not have any predictors
attribute (now you know where to check it :) ), and therefore it complains when you try to access it. As easy as that.
Although I was expecting an automatic solution (fitting to the screen automatically), resizing solves the problem as well.
import cv2
cv2.namedWindow("output", cv2.WINDOW_NORMAL) # Create window with freedom of dimensions
im = cv2.imread("earth.jpg") # Read image
imS = cv2.resize(im, (960, 540)) # Resize image
cv2.imshow("output", imS) # Show image
cv2.waitKey(0) # Display the image infinitely until any keypress
If you stored the complete model, not only the weights, in the HDF5 file, then it is as simple as
from keras.models import load_model
model = load_model('model.h5')
use this URL : "https://twitter.com/(userName)/profile_image?size=original"
If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient
, using TWTRAuthSession
.
This is the code snipe for iOS:
if let twitterId = session.userID{
let twitterClient = TWTRAPIClient(userID: twitterId)
twitterClient.loadUser(withID: twitterId) {(user, error) in
if let userName = user?.screenName{
let url = "https://twitter.com/\(userName)/profile_image?size=original")
}
}
}
This thread has some considerable debate about whether BN should be applied before non-linearity of current layer or to the activations of the previous layer.
Although there is no correct answer, the authors of Batch Normalization say that It should be applied immediately before the non-linearity of the current layer. The reason ( quoted from original paper) -
"We add the BN transform immediately before the nonlinearity, by normalizing x = Wu+b. We could have also normalized the layer inputs u, but since u is likely the output of another nonlinearity, the shape of its distribution is likely to change during training, and constraining its first and second moments would not eliminate the covariate shift. In contrast, Wu + b is more likely to have a symmetric, non-sparse distribution, that is “more Gaussian” (Hyv¨arinen & Oja, 2000); normalizing it is likely to produce activations with a stable distribution."

You can see what fonts you have available with the command windowsFonts()
. For example mine looks like this when I started looking at this:
> windowsFonts()
$serif
[1] "TT Times New Roman"
$sans
[1] "TT Arial"
$mono
[1] "TT Courier New"
After intalling the package extraFont and running font_import
like this (it took like 5 minutes):
library(extrafont)
font_import()
loadfonts(device = "win")
I had many more available - arguable too many, certainly too many to list here.
Then I tried your code:
library(ggplot2)
library(extrafont)
loadfonts(device = "win")
a <- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
ggtitle("Fuel Efficiency of 32 Cars") +
xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
theme(text=element_text(size=16, family="Comic Sans MS"))
print(a)
yielding this:
You can find the name of a font you need for the family
parameter of element_text
with the following code snippet:
> names(wf[wf=="TT Times New Roman"])
[1] "serif"
And then:
library(ggplot2)
library(extrafont)
loadfonts(device = "win")
a <- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
ggtitle("Fuel Efficiency of 32 Cars") +
xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
theme(text=element_text(size=16, family="serif"))
print(a)
After trying lots of other approaches, and lots of re-installs and checks, I have just fixed the issue by clearing out browsing data from Chrome (cached images and files) and then refreshing the page.
You can also use
./gradlew clean build
(Mac and Linux) -With ./
gradlew clean build
(Windows) -Without ./
it removes build folder, as well configure your modules and then build your project.
i use it before release any new app on playstore.
According to the Box-cox transformation formula in the paper Box,George E. P.; Cox,D.R.(1964). "An analysis of transformations", I think mlegge's post might need to be slightly edited.The transformed y should be (y^(lambda)-1)/lambda instead of y^(lambda). (Actually, y^(lambda) is called Tukey transformation, which is another distinct transformation formula.)
So, the code should be:
(trans <- bc$x[which.max(bc$y)])
[1] 0.4242424
# re-run with transformation
mnew <- lm(((y^trans-1)/trans) ~ x) # Instead of mnew <- lm(y^trans ~ x)

You should run:
composer dump-autoload
and if does not work you should:
re-install composer

Besides polyfill, I use babel-plugin-transform-runtime. The plugin is described as:
Externalize references to helpers and builtins, automatically polyfilling your code without polluting globals. What does this actually mean though? Basically, you can use built-ins such as Promise, Set, Symbol etc as well use all the Babel features that require a polyfill seamlessly, without global pollution, making it extremely suitable for libraries.
It also includes support for async/await along with other built-ins of ES 6.
$ npm install --save-dev babel-plugin-transform-runtime
In .babelrc
, add the runtime plugin
{
"plugins": [
["transform-runtime", {
"regenerator": true
}]
]
}
Note If you're using babel 7, the package has been renamed to @babel/plugin-transform-runtime.
Syntax of JSON
object = {} | { members }
array = [] | [ elements ]

You can try to use the parameter "enable-automation"
var options = new ChromeOptions();
// hide selenium
options.AddExcludedArguments(new List<string>() { "enable-automation" });
var driver = new ChromeDriver(ChromeDriverService.CreateDefaultService(), options);
But, I want to warn that this ability was fixed in ChromeDriver 79.0.3945.16. So probably you should use older versions of chrome.
Also, as another option, you can try using InternetExplorerDriver instead of Chrome. As for me, IE does not block at all without any hacks.
And for more info try to take a look here:
Selenium webdriver: Modifying navigator.webdriver flag to prevent selenium detection
Unable to hide "Chrome is being controlled by automated software" infobar within Chrome v76
You can do it like this:
In your main view controller:
func showModal() {
let modalViewController = ModalViewController()
modalViewController.modalPresentationStyle = .overCurrentContext
presentViewController(modalViewController, animated: true, completion: nil)
}
In your modal view controller:
class ModalViewController: UIViewController {
override func viewDidLoad() {
view.backgroundColor = UIColor.clearColor()
view.opaque = false
}
}
If you are working with a storyboard:
Just add a Storyboard Segue with Kind
set to Present Modally
to your modal view controller and on this view controller set the following values:
As Crashalot pointed out in his comment: Make sure the segue only uses Default
for both Presentation
and Transition
. Using Current Context
for Presentation
makes the modal turn black instead of remaining transparent.
to anyone looking for solution to the flickering/blinking issue when you already have DividerItemDecoration
. i seem to have solved it like this:
override fun onDrawOver(...)
{
//code from before
//do NOT return on null
val childInContact = getChildInContact(recyclerView, currentHeader.bottom)
//add null check
if (childInContact != null && mHeaderListener.isHeader(recyclerView.getChildAdapterPosition(childInContact)))
{
moveHeader(...)
return
}
drawHeader(...)
}
this seems to be working but can anyone confirm i did not break anything else?
For react-router
2.4.0+
NOTE: It is advisable to migrate all your code to the latest react-router
to get all the new goodies.
As recommended in the react-router documentation:
One should use the withRouter
higher order component:
We think this new HoC is nicer and easier, and will be using it in documentation and examples, but it is not a hard requirement to switch.
As an ES6 example from the documentation:
import React from 'react'
import { withRouter } from 'react-router'
const Page = React.createClass({
componentDidMount() {
this.props.router.setRouteLeaveHook(this.props.route, () => {
if (this.state.unsaved)
return 'You have unsaved information, are you sure you want to leave this page?'
})
}
render() {
return <div>Stuff</div>
}
})
export default withRouter(Page)
numpy.random.randint
accepts a third argument (size
) , in which you can specify the size of the output array. You can use this to create your DataFrame
-
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
Here - np.random.randint(0,100,size=(100, 4))
- creates an output array of size (100,4)
with random integer elements between [0,100)
.
Demo -
import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
which produces:
A B C D
0 45 88 44 92
1 62 34 2 86
2 85 65 11 31
3 74 43 42 56
4 90 38 34 93
5 0 94 45 10
6 58 23 23 60
.. .. .. .. ..
for me the fix was to add the injected class as inner class in the one annotated with @ConfigurationProperites, because I think you need @Component to inject properties.
In case you'd like to do it with async:
const request = async <T>(param1: string, param2: number) => {
const res = await func();
return res.response() as T;
}
And a more complex pattern, in case you'd like to wrap your function inside a generic counterpart, such as memoization (Example uses fast-memoize):
const request = memoize(
async <T>(
url: string,
token?: string
) => {
// Perform your code here
}
);
See how you define the generic after the memoizing function.
I'm running Microsoft Windows 10 Pro, Version 10.0.17763 Build 17763, and I see my .ssh folder easily at C:\Users\jrosario\.ssh without having to edit permissions or anything (though in File Explorer, I did select "Show hidden files, folders and drives"):
The keys are stored in a text file named known_hosts, which looks roughly like this:
Pattern based configs are scheduled for 2.0.0 release of ESLint. For now, however, you will have to create two separate tasks (as mentioned in the comments). One for tests and one for the rest of the code and run both of them, while providing different .eslintrc files.
P.S. There's a jest environment coming in the next release of ESLint, it will register all of the necessary globals.
I have had a similar scenario in Laravel and solved it in the following way.
The password contains characters from at least three of the following five categories:
First, we need to create a regular expression and validate it.
Your regular expression would look like this:
^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$
I have tested and validated it on this site. Yet, perform your own in your own manner and adjust accordingly. This is only an example of regex, you can manipluated the way you want.
So your final Laravel code should be like this:
'password' => 'required|
min:6|
regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$/|
confirmed',
Update As @NikK in the comment mentions, in Laravel 5.5 and newer the the password value should encapsulated in array Square brackets like
'password' => ['required',
'min:6',
'regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$/',
'confirmed']
I have not testing it on Laravel 5.5 so I am trusting @NikK hence I have moved to working with c#/.net these days and have no much time for Laravel.
Note:
Some online references
Regarding your custom validation message for the regex rule in Laravel, here are a few links to look at:
just get into the zabbix.conf.php
>$sudo vim /etc/zabbix/web/zabbix.conf.php
>$ZBX_SERVER = '**your zabbix ip address or DNS name**';
>$ZBX_SERVER_PORT = '10051';
>$ZBX_SERVER_NAME = '**your zabbix hostname**';
just change the ip address you can resolve the error
Zabbix server is not running: the information displayed may not be current
After that restart the zabbix server
>$sudo service zabbix-server restart
To verify go to Dashboard Administration -> queue there you see data
i resolved my error like this works fine for me.
In the Divi Theme Documentation, it says that the theme comes with access to 'ePanel' which also has an 'Integration' section.
You should be able to add this code:
<script>
$( ".et-pb-icon" ).click(function() {
$( this ).toggleClass( "active" );
});
</script>
into the the box that says 'Add code to the head of your blog' under the 'Integration' tab, which should get the jQuery working.
Then, you should be able to style your class to what ever you need.
referring to radio buttons ,you can also do it with Segmented Control as following:
step 1: drag a segmented control to your view in the attribute inspector change the title of the two segments ,for example "Male" and "Female"
step 2: create an outlet & an action for it in the code
step 3: create a variable for future use to contain choice's data
in the code do as following:
@IBOutlet weak var genderSeg: UISegmentedControl!
var genderPick : String = ""
@IBAction func segAction(_ sender: Any) {
if genderSeg.selectedSegmentIndex == 0 {
genderPick = "Male"
print(genderPick)
} else if genderSeg.selectedSegmentIndex == 1 {
genderPick = "Female"
print(genderPick)
}
}
Ok, so, I found this answer very helpful and thanks to all the people who contributed. Just to add something, though. The accepted answer is indeed the correct answer...BUT...in my case, I was looking to implement the error message below the EditText
widget with app:errorEnabled="true"
and this single line made my life difficult. it seems that this overrides the theme I chose for android.support.design.widget.TextInputLayout
, which has a different text color defined by android:textColorPrimary
.
In the end I took to applying a text color directly to the EditText
widget. My code looks something like this:
styles.xml
<item name="colorPrimary">@color/my_yellow</item>
<item name="colorPrimaryDark">@color/my_yellow_dark</item>
<item name="colorAccent">@color/my_yellow_dark</item>
<item name="android:textColorPrimary">@android:color/white</item>
<item name="android:textColorSecondary">@color/dark_gray</item>
<item name="android:windowBackground">@color/light_gray</item>
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:textColorHint">@color/dark_gray</item>
<item name="android:colorControlNormal">@android:color/black</item>
<item name="android:colorControlActivated">@android:color/white</item>
And my widget:
<android.support.design.widget.TextInputLayout
android:id="@+id/log_in_layout_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:errorEnabled="true">
<EditText
android:id="@+id/log_in_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textColor="@android:color/black"
android:ems="10"
android:hint="@string/log_in_name"
android:inputType="textPersonName" />
</android.support.design.widget.TextInputLayout>
Now it displays black text color instead of the textColorPrimary
white.
for me it was a problem with lfs files that were not downloaded
git lfs fetch --all
fixed the problem.
To check a space symbol you can use the following approach
if ( c == ' ' ) { /*...*/ }
To check a space and/or a tab symbol (standard blank characters) you can use the following approach
#include <ctype.h>
//...
if ( isblank( c ) ) { /*...*/ }
To check a white space you can use the following approach
#include <ctype.h>
//...
if ( isspace( c ) ) { /*...*/ }
An alternative to AtomicInteger
is to use an array (or any other object able to store a value):
final int ordinal[] = new int[] { 0 };
list.forEach ( s -> s.setOrdinal ( ordinal[ 0 ]++ ) );
But see the Stuart's answer: there might be a better way to deal with your case.
If you can produce a small demo showing the onMouseEnter / onMouseLeave or onMouseDown / onMouseUp bug, it would be worthwhile to post it to ReactJS's issues page or mailing list, just to raise the question and hear what the developers have to say about it.
In your use case, you seem to imply that CSS :hover and :active states would be enough for your purposes, so I suggest you use them. CSS is orders of magnitude faster and more reliable than Javascript, because it's directly implemented in the browser.
However, :hover and :active states cannot be specified in inline styles. What you can do is assign an ID or a class name to your elements and write your styles either in a stylesheet, if they are somewhat constant in your application, or in a dynamically generated <style>
tag.
Here's an example of the latter technique: https://jsfiddle.net/ors1vos9/
pip when used with virtualenv will generally install packages in the path <virtualenv_name>/lib/<python_ver>/site-packages
.
For example, I created a test virtualenv named venv_test with Python 2.7, and the django
folder is in venv_test/lib/python2.7/site-packages/django
.
Here it is in maven, with the property so you can survive between spring boot upgrades
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>

<version>${jackson.version}</version>
</dependency>
here is another example for changing the arrows and using your own arrow-images.
.slick-prev:before {
background-image: url('images/arrow-left.png');
background-size: 50px 50px;
display: inline-block;
width: 50px;
height: 50px;
content:"";
}
.slick-next:before {
background-image: url('images/arrow-right.png');
background-size: 50px 50px;
display: inline-block;
width: 50px;
height: 50px;
content:"";
}
You can use sklearn.preprocessing:
from sklearn.preprocessing import normalize
data = np.array([
[1000, 10, 0.5],
[765, 5, 0.35],
[800, 7, 0.09], ])
data = normalize(data, axis=0, norm='max')
print(data)
>>[[ 1. 1. 1. ]
[ 0.765 0.5 0.7 ]
[ 0.8 0.7 0.18 ]]
This happens with images for which the script does not launch a service awaiting requests, therefore the container exits at the end of the script.
This is typically the case with most base OS images (centos, debian, etc.), or also with the node images.
Your best bet is to run the image in interactive mode. Example below with the node image:
docker run -it node /bin/bash
Output is
root@cacc7897a20c:/# echo $SHELL
/bin/bash
import { Route, Redirect } from "react-router-dom";
class App extends Component {
render() {
return (
<div>
<Route path='/'>
<Redirect to="/something" />
</Route>
//rest of code here
this will make it so that when you load up the server on local host it will re direct you to /something
If you don't care about the columns where the missing files are, considering that the dataframe has the name New
and one wants to assign the new dataframe to the same variable, simply run
New = New.drop_duplicates()
If you specifically want to remove the rows for the empty values in the column Tenant
this will do the work
New = New[New.Tenant != '']
This may also be used for removing rows with a specific value - just change the string to the value that one wants.
Note: If instead of an empty string one has NaN
, then
New = New.dropna(subset=['Tenant'])
Simple solution for me: sudo docker-compose up
UPDATE 2016-3-14: At some point in the docker install process (or docker-compose ?) there is a suggestion and example to add your username to the "docker" group. This allows you to avoid needing "sudo" before all docker commands, like so:
~ > docker run -it ubuntu /bin/bash
root@665d1ea76b8d:/# date
Mon Mar 14 23:43:36 UTC 2016
root@665d1ea76b8d:/# exit
exit
~ >
Look carefully at the output of the install commands (both docker & the 2nd install for docker-compose) and you'll find the necessary step. It is also documented here: https://subosito.com/posts/docker-tips/
Sudo? No!
Tired of typing sudo docker everytime you issue a command? Yeah, there is a way for dealing with that. Although naturally docker is require a root user, we can give a root-equivalent group for docker operations.
You can create a group called docker, then add desired user to that group. After restarting docker service, the user will no need to type sudo each time do docker operations. How it looks like on a shell commands? as a root, here you go:
> sudo groupadd docker
> sudo gpasswd -a username docker
> sudo service docker restart
Done!
This section contains optional procedures for configuring Linux hosts to work better with Docker.
Manage Docker as a non-root user
The docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can only access it using sudo. The docker daemon always runs as the root user.
If you don’t want to use sudo when you use the docker command, create a Unix group called docker and add users to it. When the docker daemon starts, it makes the ownership of the Unix socket read/writable by the docker group.
To create the docker group and add your user:
# 1. Create the docker group.
$ sudo groupadd docker
# 2. Add your user to the docker group.
$ sudo usermod -aG docker $USER
# 3. Log out and log back in so that your group membership is re-evaluated.
# 4. Verify that you can run docker commands without sudo.
$ docker run hello-world
This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.
Swift 3 / Swift 4 Update:
let screenSize: CGRect = UIScreen.main.bounds
let myView = UIView(frame: CGRect(x: 0, y: 0, width: screenSize.width - 10, height: 10))
self.view.addSubview(myView)
Answer given by kennyut/Kistian works very well but to get exact RDD like output when RDD consist of list of attributes e.g. [1,2,3,4] we can use flatmap command as below,
rdd = df.rdd.flatMap(list)
or
rdd = df.rdd.flatmap(lambda x: list(x))
In your webpack.config.js file add below:
var webpack = require("webpack");
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery"
})
],
Install jQuery using npm:
$ npm i jquery --save
In app.js file add below lines:
import $ from 'jquery';
window.jQuery = $;
window.$ = $;
This worked for me. :)
mine was DispatchQueue.main.sync inside the closer I made it DispatchQueue.main.async and it worked.
So if you go to
-> Setting -> Project:My_project -> Project Structure,
Just the directory in which the source code is available and mark it as "Sources" (You can see it on the same window). The directory with source code should turn blue. Now u can import in modules residing in same directory.
I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.
It is neither an API nor a framework. It is just an architectural concept. You can find more details here.
I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.
EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.
It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).
Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.
As such there is no direct method to copy or rename index in ES (I did search extensively for my own project)
However a very easy option is to use a popular migration tool [Elastic-Exporter].

[PS: this is not my blog, just stumbled upon and found it good]
Thereby you can copy index/type and then delete the old one.
It might be obvious, but make sure that you are sending to the parser URL object not a String containing www adress. This will not work:
ObjectMapper mapper = new ObjectMapper();
String www = "www.sample.pl";
Weather weather = mapper.readValue(www, Weather.class);
But this will:
ObjectMapper mapper = new ObjectMapper();
URL www = new URL("http://www.oracle.com/");
Weather weather = mapper.readValue(www, Weather.class);
Thanks to Mike's comment, I've re-read the doc and I've realised that my current user (i.e. userA that already has the create privilege) wasn't a direct/indirect member of the new owning role...
So the solution was quite simple - I've just done this grant:
grant userB to userA;
That's all folks ;-)
Another requirement is that the object has to be owned by user userA before altering it...
Passing a parameter to gulp can mean a few things:
Here's an approach of passing parameters from the main gulpfile to a gulp task. By moving the task that needs the parameter to it's own module and wrapping it in a function (so a parameter can be passed).:
// ./gulp-tasks/my-neat-task.js file
module.exports = function(opts){
opts.gulp.task('my-neat-task', function(){
console.log( 'the value is ' + opts.value );
});
};
//main gulpfile.js file
//...do some work to figure out a value called val...
var val = 'some value';
//pass that value as a parameter to the 'my-neat-task' gulp task
require('./gulp-tasks/my-neat-task.js')({ gulp: gulp, value: val});
This can come in handy if you have a lot of gulp tasks and want to pass them some handy environmental configs. I'm not sure if it can work between one task and another.
Try to check installed global packages npm list -g --depth=0
. If you will not find nodemon
, - install it with flag -g
or --save-dev
. Don't install nodemon
with flag --save
, because nodemon
uses only for development
.
Os X Mojave 10.14 has:
Error: The Command Line Tools header package must be installed on Mojave.
Solution. Go to
/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
location and install the package manually. And brew will start working and we can run:
brew uninstall --force git
brew cleanup --force -s git
brew prune
brew install git
You could also use the RouteHandler mixin to avoid the wrapper component and more easily pass down the parent's state as props:
var Dashboard = require('./Dashboard');
var Comments = require('./Comments');
var RouteHandler = require('react-router/modules/mixins/RouteHandler');
var Index = React.createClass({
mixins: [RouteHandler],
render: function () {
var handler = this.getRouteHandler({ myProp: 'value'});
return (
<div>
<header>Some header</header>
{handler}
</div>
);
}
});
var routes = (
<Route path="/" handler={Index}>
<Route path="comments" handler={Comments}/>
<DefaultRoute handler={Dashboard}/>
</Route>
);
ReactRouter.run(routes, function (Handler) {
React.render(<Handler/>, document.body);
});
You can use a vector. Instead of worry about different screen sizes you only need to create an .svg file and import it to your project using Vector Asset Studio.
If you are developing to a modern browser. https://caniuse.com/#search=fit%20content
You can use:
width: fit-content;
In Swift 5 it looks like this:
label.translatesAutoresizingMaskIntoConstraints = false
label.centerXAnchor.constraint(equalTo: vc.view.centerXAnchor).isActive = true
label.centerYAnchor.constraint(equalTo: vc.view.centerYAnchor).isActive = true
Similar to the accepted solution, but you can replace the
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
with
let button = UIButton()
Here is the full solution, enjoy: (it's just a bit cleaner than the accepted solution)
let button = UIButton()
button.frame = CGRectMake(0, 0, 51, 31) //won't work if you don't set frame
button.setImage(UIImage(named: "fb"), forState: .Normal)
button.addTarget(self, action: Selector("fbButtonPressed"), forControlEvents: .TouchUpInside)
let barButton = UIBarButtonItem()
barButton.customView = button
self.navigationItem.rightBarButtonItem = barButton
From Android Support Library 23.2.1 update, all WRAP_CONTENT should work correctly.
Please update version of a library in gradle
file OR to further :
compile 'com.android.support:recyclerview-v7:23.2.1'
solved some issue like Fixed bugs related to various measure-spec methods
Check http://developer.android.com/tools/support-library/features.html#v7-recyclerview
you can check Support Library revision history
Another situation that can cause this problem is incorrect casting in your queries.
I know it may sound obvious, but I have run into this by using tablename
instead of Tablename
. Check your queries, and make sure that you're using the same case as the actual names of the columns in your table.
In Swift 4.2 and Xcode 10.1
Add image for selected UIButton
button.addTarget(self, action: #selector(self.onclickDateCheckMark), for: .touchUpInside)//Target
button.setImage(UIImage.init(named: "uncheck"), for: UIControl.State.normal)//When selected
button.setImage(UIImage.init(named: "check"), for: UIControl.State.highlighted)//When highlighted
button.setImage(UIImage.init(named: "check"), for: UIControl.State.selected)//When selected
But if you want to change selected button image you need to change it's selected state. Then only selected image will appear in your button.
@objc func onclickDateCheckMark(sender:UIButton) {
if sender.isSelected == true {
sender.isSelected = false
print("not Selected")
}else {
sender.isSelected = true
print("Selected")
}
}
How long is the list you're going to normalize?
def psum(it):
"This function makes explicit how many calls to sum() are done."
print "Another call!"
return sum(it)
raw = [0.07,0.14,0.07]
print "How many calls to sum()?"
print [ r/psum(raw) for r in raw]
print "\nAnd now?"
s = psum(raw)
print [ r/s for r in raw]
# if one doesn't want auxiliary variables, it can be done inside
# a list comprehension, but in my opinion it's quite Baroque
print "\nAnd now?"
print [ r/s for s in [psum(raw)] for r in raw]
Output
# How many calls to sum()?
# Another call!
# Another call!
# Another call!
# [0.25, 0.5, 0.25]
#
# And now?
# Another call!
# [0.25, 0.5, 0.25]
#
# And now?
# Another call!
# [0.25, 0.5, 0.25]
v22.1
of appcompat-v7
introduced some new possibilities. Now it's possible to assign a specific theme only to one view.
Deprecated use of app:theme for styling Toolbar. You can now use android:theme for toolbars on all API level 7 and higher devices and android:theme support for all widgets on API level 11 and higher devices.
So instead of setting the desired color in a global theme, we create a new one and assign it only to the Button
Example:
<style name="MyColorButton" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorButtonNormal">@color/myColor</item>
</style>
And use this style as theme of your Button
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

I had similar problem with the shadow. The shadow is drawn by direct parent of AppBarLayout in my case. If height of the parent is the same as AppBarLayout's the shadow cannot be drawn. So checking size of the parent layout and maybe layout remake can solve the problem. https://www.reddit.com/r/androiddev/comments/6xddb0/having_a_toolbar_as_a_fragment_the_shadow/
I worked out a working solution to this problem after 2 days of struggle, below solution is perfect for them who want to change few edit text only, change/toggle color through java code, and want to overcome the problems of different behavior on OS versions due to use setColorFilter() method.

In my case Product Clean and then restarting Xcode did resolve this problem...
For me, the problem was that in Android 5.0 the android:colorButtonNormal
had no effect, and actually, no item from the theme (like android:colorAccent
), but in Android 4.4.3, for example, did. The project was configured with compileSdkVersion
and targetSdkVersion
to 22, so I've made all the changes as @Muhammad Alfaifi sugessted, but in the end, I've noticed that the problem was the buildToolsVersion, that wasn't updated. Once I changed to 23.0.1, everything start working almost as normal. Now, the android:colorButtonNormal
still has no effect, but at least the button reacts to android:colorAccent
, which for me is acceptable.
I hope that this hint could help someone.
Note: I've applied the style directly to the button, since the button's android:theme=[...]
also didn't have effect.
Changing compile 'com.android.support:appcompat-v7:21.0.0'
into compile 'com.android.support:appcompat-v7:20.0.0'
in gradle.build works for me.
Your problem is actually a simple transform acting on the columns:
def f(s):
return s/s.max()
frame.apply(f, axis=0)
Or even more terse:
frame.apply(lambda x: x/x.max(), axis=0)
I had issues getting through a form because of this error.
I used Ctrl+Click to click the submit button and navigate through the form as usual.
For calling the method of one class within the second class, you have to first create the object of that class which method you want to call than with the object reference you can call the method.
class A {
public void fun(){
//do something
}
}
class B {
public static void main(String args[]){
A obj = new A();
obj.fun();
}
}
But in your case you have the static method in Date and TemperatureRange class. You can call your static method by using the class name directly like below code or by creating the object of that class like above code but static method ,mostly we use for creating the utility classes, so best way to call the method by using class name. Like in your case -
public static void main (String[] args){
String dateVal = Date.date("01","11,"12"); // calling the date function by passing some parameter.
String tempRangeVal = TemperatureRange.TempRange("80","20");
}
It's also possible to typecast an object to an array. That worked for me here.
(array) $object;
will convert
stdClass Object
(
[id] => 4
)
to
Array(
[id] => 4
)
Had the same problem when trying to pass data from query builder to a view. Since data comes as object. So you can do:
$view = view('template', (array) $object);
And in your view you use variables like
{{ $id }}
This problem really cost me some hours.
My system is Ubuntu 14.04, I installed docker by sudo apt-get install docker
, and typed some other commands that caused the problem.
I google "unknown job: docker.io", answers did not take effect.
I looked for reasons of "unknown job" in /etc/init.d/
, found no proper answer .
I looked for way to debug script in /etc/init.d/
, found no proper answer.
Then, I did a clean:
sudo apt-get remove docker.io
find / -name "*docker*"
, such as /etc/init/docker.io.conf
, /etc/init.d/docker.io
.Follow the latest official document: https://docs.docker.com/installation/, there is a lot of outdated documentation which can be misleading.
Finally, it fixed the problem.
Note: If you are in China, because of the GFW, you may need to set the https_proxy to install docker from https://get.docker.com/ .
If the worksheet you want to retrieve exists at compile-time in ThisWorkbook
(i.e. the workbook that contains the VBA code you're looking at), then the simplest and most consistently reliable way to refer to that Worksheet
object is to use its code name:
Debug.Print Sheet1.Range("A1").Value
You can set the code name to anything you need (as long as it's a valid VBA identifier), independently of its "tab name" (which the user can modify at any time), by changing the (Name)
property in the Properties toolwindow (F4):
The Name
property refers to the "tab name" that the user can change on a whim; the (Name)
property refers to the code name of the worksheet, and the user can't change it without accessing the Visual Basic Editor.
VBA uses this code name to automatically declare a global-scope Worksheet
object variable that your code gets to use anywhere to refer to that sheet, for free.
In other words, if the sheet exists in ThisWorkbook
at compile-time, there's never a need to declare a variable for it - the variable is already there!
If the worksheet is created at run-time (inside ThisWorkbook
or not), then you need to declare & assign a Worksheet
variable for it.
Use the Worksheets
property of a Workbook
object to retrieve it:
Dim wb As Workbook
Set wb = Application.Workbooks.Open(path)
Dim ws As Worksheet
Set ws = wb.Worksheets(nameOrIndex)
Both the name and index of a worksheet can easily be modified by the user (accidentally or not), unless workbook structure is protected. If workbook isn't protected, you simply cannot assume that the name or index alone will give you the specific worksheet you're after - it's always a good idea to validate the format of the sheet (e.g. verify that cell A1 contains some specific text, or that there's a table with a specific name, that contains some specific column headings).
Using the Sheets
collection contains Worksheet
objects, but can also contain Chart
instances, and a half-dozen more legacy sheet types that are not worksheets. Assigning a Worksheet
reference from whatever Sheets(nameOrIndex)
returns, risks throwing a type mismatch run-time error for that reason.
Not qualifying the Worksheets
collection is an implicit ActiveWorkbook reference - meaning the Worksheets
collection is pulling from whatever workbook is active at the moment the instruction is executing. Such implicit references make the code frail and bug-prone, especially if the user can navigate and interact with the Excel UI while code is running.
Unless you mean to activate a specific sheet, you never need to call ws.Activate
in order to do 99% of what you want to do with a worksheet. Just use your ws
variable instead.
In case you are like me, and cannot work out how to use "regular expression with capturing groups" for extract
, the following code replicates the extract(...)
line in Hadleys' answer:
df %>%
gather(question_number, value, starts_with("Q3.")) %>%
mutate(loop_number = str_sub(question_number,-2,-2), question_number = str_sub(question_number,1,4)) %>%
select(id, time, loop_number, question_number, value) %>%
spread(key = question_number, value = value)
The problem here is that the initial gather forms a key column that is actually a combination of two keys. I chose to use mutate
in my original solution in the comments to split this column into two columns with equivalent info, a loop_number
column and a question_number
column. spread
can then be used to transform the long form data, which are key value pairs (question_number, value)
to wide form data.
If you have a container running as root that runs a script (which you can't change) that needs access to the sudo
command, you can simply create a new sudo
script in your $PATH
that calls the passed command.
e.g. In your Dockerfile:
RUN if type sudo 2>/dev/null; then \
echo "The sudo command already exists... Skipping."; \
else \
echo -e "#!/bin/sh\n\${@}" > /usr/sbin/sudo; \
chmod +x /usr/sbin/sudo; \
fi
I got the same error message for two separate reasons, so you can add them to your debugging checklist:
Context: Xcode 6.4, iOS:8.4. I was adding a toolbar with custom UIBarButton
s to load with the UIKeyboardTypeNumberPad
(Swift: UIKeyboardType.numberPad
) , namely "Done" and "+/-". I had this problem when:
My UIToolbar was declared as a property, but I had forgotten to explicitly alloc/init it.
I had left off the last line, [myCustomToolbar sizeToFit];
, which sounds like it's the same family as Holden's answer (my code here: https://stackoverflow.com/a/32016397/4898050).
Good luck
Simple idea: get the lenght of the longest row, iterate over each column printing the content of a row if it has elements. The below code might have some off-by-one errors as it was coded in a simple text editor.
int longestRow = 0;
for (int i = 0; i < array.length; i++) {
if (array[i].length > longestRow) {
longestRow = array[i].length;
}
}
for (int j = 0; j < longestRow; j++) {
for (int i = 0; i < array.length; i++) {
if(array[i].length > j) {
System.out.println(array[i][j]);
}
}
}
I've tried in a sample project to use standard, @2x and @3x images, and the iPhone 6+ simulator uses the @3x image. So it would seem that there are @3x images to be done (if the simulator actually replicates the device's behavior).
But the strange thing is that all devices (simulators) seem to use this @3x image when it's on the project structure, iPhone 4S/iPhone 5 too.
The lack of communication from Apple on a potential @3x structure, while they ask developers to publish their iOS8 apps is quite confusing, especially when seeing those results on simulator.
**Edit from Apple's Website **: Also found this on the "What's new on iOS 8" section on Apple's developer space :
Support for a New Screen Scale The iPhone 6 Plus uses a new Retina HD display with a screen scale of 3.0. To provide the best possible experience on these devices, include new artwork designed for this screen scale. In Xcode 6, asset catalogs can include images at 1x, 2x, and 3x sizes; simply add the new image assets and iOS will choose the correct assets when running on an iPhone 6 Plus. The image loading behavior in iOS also recognizes an @3x suffix.
Still not understanding why all devices seem to load the @3x. Maybe it's because I'm using regular files and not xcassets ? Will try soon.
Edit after further testing : Ok it seems that iOS8 has a talk in this. When testing on an iOS 7.1 iPhone 5 simulator, it uses correctly the @2x image. But when launching the same on iOS 8 it uses the @3x on iPhone 5. Not sure if that's a wanted behavior or a mistake/bug in iOS8 GM or simulators in Xcode 6 though.
You can use PowerShell.

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.
Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.
In this case I'd ask why you're including both cstdlib
and stdlib.h
; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib
puts them in the namespace std
in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!
Anyway, your use of using namespace std
(which I would recommend against, in future) means that std::system
from cstdlib
now conflicts with system
from stdlib.h
. I can't explain what's going on with std::cout
and std::cin
.
Try removing #include <stdlib.h>
and see what happens.
If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.
So the answer seems to be to NOT use the Solution Explorer search box.
Rather, open any file in the solution, then use the control-f search pop-up to search all files by:
A few comments:
analog=True
in the call to butter
, and you should use scipy.signal.freqz
(not freqs
) to generate the frequency response.Here's my modified version of your script, followed by the plot that it generates.
import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt
def butter_lowpass(cutoff, fs, order=5):
nyq = 0.5 * fs
normal_cutoff = cutoff / nyq
b, a = butter(order, normal_cutoff, btype='low', analog=False)
return b, a
def butter_lowpass_filter(data, cutoff, fs, order=5):
b, a = butter_lowpass(cutoff, fs, order=order)
y = lfilter(b, a, data)
return y
# Filter requirements.
order = 6
fs = 30.0 # sample rate, Hz
cutoff = 3.667 # desired cutoff frequency of the filter, Hz
# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)
# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()
# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0 # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data. We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)
# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)
plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()
plt.subplots_adjust(hspace=0.35)
plt.show()
Yet another usage of th:class, same as @NewbLeech and @Charles have posted, but simplified to maximum if there is no "else" case:
<input th:class="${#fields.hasErrors('password')} ? formFieldHasError" />
Does not include class attribute if #fields.hasErrors('password') is false.
You may have some problems if you use return false or stopPropagation() method because your events will be interrupted. Try this code, it's works fine:
$(function() {
$('.dropdown').on("click", function (e) {
$('.keep-open').removeClass("show");
});
$('.dropdown-toggle').on("click", function () {
$('.keep-open').addClass("show");
});
$( ".closeDropdown" ).click(function() {
$('.dropdown').closeDropdown();
});
});
jQuery.fn.extend({
closeDropdown: function() {
this.addClass('show')
.removeClass("keep-open")
.click()
.addClass("keep-open");
}
});
In HTML:
<div class="dropdown keep-open" id="search-menu" >
<button class="btn dropdown-toggle btn btn-primary" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<i class="fa fa-filter fa-fw"></i>
</button>
<div class="dropdown-menu">
<button class="dropdown-item" id="opt1" type="button">Option 1</button>
<button class="dropdown-item" id="opt2" type="button">Option 2</button>
<button type="button" class="btn btn-primary closeDropdown">Close</button>
</div>
</div>
If you want to close the dropdrown:
`$('#search-menu').closeDropdown();`
try this
html
<div ng-controller="MyCtrl">
Hello, {{newDate | date:'MM/dd/yyyy'}}!
</div>
JS
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
var collectionDate = '2002-04-26T09:00:00';
$scope.newDate =new Date(collectionDate);
}
If using the following HTML:
<button id="submit-button"></button>
Style can be applied through JS using the style object available on an HTMLElement.
To set height and width to 200px of the above example button, this would be the JS:
var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';
I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.
Under your reference, you have this:
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">

<link src="http://maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">
Have you tried replacing src=

I don't think the accepted solution handles the case where the error text is reported on stderr. From my testing the exception's output attribute did not contain the results from stderr and the docs warn against using stderr=PIPE in check_output(). Instead, I would suggest one small improvement to J.F Sebastian's solution by adding stderr support. We are, after all, trying to handle errors and stderr is where they are often reported.
from subprocess import Popen, PIPE
p = Popen(['bitcoin', 'sendtoaddress', ..], stdout=PIPE, stderr=PIPE)
output, error = p.communicate()
if p.returncode != 0:
print("bitcoin failed %d %s %s" % (p.returncode, output, error))

Return code is: 401, ReasonPhrase: Unauthorized. -> [Help 1]
Solution:
In this case you need to change the version in the pom file, and try to use a new version.
Here 01.16.03 already exist so it was failing and when i have tried with the 01.16.04 version the job went successful.
You need to map the unique route to specify your parameters as query elements. In RouteConfig.cs (or WebApiConfig.cs) add:
config.Routes.MapHttpRoute(
name: "MyPagedQuery",
routeTemplate: "api/{controller}/{action}/{firstId}/{countToFetch}",
defaults: new { action = "GetNDepartmentsFromID" }
);
for Z score, we can stick to documentation instead of using 'apply' function
from scipy.stats import zscore
df_zscore = zscore(cols as array, axis=1)

Another silly mistake that will cause this error is repeated files. I accidentally copied some files twice. First I went to Targets -> Build Phases -> Compile sources. There I noticed some files on that list twice and their locations.
I recently ran into similar issues, and this is what worked for me.
If the variable is numeric, then a simple df$Var[df$Var == ""] <- NA
should suffice. But if the variable is a factor, then you need to convert it to the character first, then replace ""
cells with the value you want, and convert it back to factor. So case in point, your Sex
variable, I assume it would be a factor and if you want to replace the empty cell, I would do the following:
df$Var <- as.character(df$Var)
df$Var[df$Var==""] <- NA
df$Var <- as.factor(df$Var)

This is how you can create a beautiful button with a bezel and rounded edges:
loginButton = UIButton(frame: CGRectMake(self.view.bounds.origin.x + (self.view.bounds.width * 0.325), self.view.bounds.origin.y + (self.view.bounds.height * 0.8), self.view.bounds.origin.x + (self.view.bounds.width * 0.35), self.view.bounds.origin.y + (self.view.bounds.height * 0.05)))

loginButton.setTitleColor(UIColor(red: 24.0/100, green: 116.0/255, blue: 205.0/205, alpha: 1.0), forState: UIControlState.Normal)
There are two distinct uses of mipmaps:
For launcher icons when building density specific APKs. Some developers build separate APKs for every density, to keep the APK size down. However some launchers (shipped with some devices, or available on the Play Store) use larger icon sizes than the standard 48dp. Launchers use getDrawableForDensity and scale down if needed, rather than up, so the icons are high quality. For example on an hdpi tablet the launcher might load the xhdpi icon. By placing your launcher icon in the mipmap-xhdpi directory, it will not be stripped the way a drawable-xhdpi directory is when building an APK for hdpi devices. If you're building a single APK for all devices, then this doesn't really matter as the launcher can access the drawable resources for the desired density.
The actual mipmap API from 4.3. I haven't used this and am not familiar with it. It's not used by the Android Open Source Project launchers and I'm not aware of any other launcher using.
I get this error too when creating a project in IntelliJ without using a template.
I have 2 SDKs installed: Amazon Corretto and java version 11.0.4 and so, what I do when I have this error is "change the SDK" it usually works fine with Corretto
to do that you need to click on File (in IntelliJ)/ Project Structure / Project / Project SDK: select corretto from the dropdown list (or check the option in your computer) as shown here
hope this will work for you too
Best, Constantin
If anyone came here to resolve an error with react-native-fbsdk
after installing it using Cocoapods
, keep in mind that you have to remove all the other .a files in your Projects build phases and only keep the .a from cocoapods called libPods-WhateverAppName.a
.
This is usually caused from running rnpm link
and the way rnpm works.
After I removed the facebook core .a file from my build phases my project was up and running once again.
It's also important to note that MongoDB has the concept of "authentication database", which can be different than the database you are connecting to. For example, if you use the official Docker image for Mongo and specify the environment variables MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD, a user will be created on 'admin' database, which is probably not the database you want to use. In this case, you should specify parameters accordingly on your application.properties file using:
spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.port=27017
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.username=<username specified on MONGO_INITDB_ROOT_USERNAME>
spring.data.mongodb.password=<password specified on MONGO_INITDB_ROOT_PASSWORD>
spring.data.mongodb.database=<the db you want to use>
You need to encode it yourself by escaping strings with URLEncoder and joining them with "="
and "&"
. Or you can use FormEncoder from Mimecraft which gives you a handy builder.
FormEncoding fe = new FormEncoding.Builder()
.add("name", "Lorem Ipsum")
.add("occupation", "Filler Text")
.build();
I got this answer from here. and its works for me

To help you with your problem I found this blog which talks about making laravel production optimized. Most of what you need to do to make your app fast would now be in the hands of how efficient your code is, your network capacity, CDN, caching, database.
Now I will talk about the issue:
Laravel is slow out of the box. There are ways to optimize it. You also have the option of using caching in your code, improving your server machine, yadda yadda yadda. But in the end Laravel is still slow.
Laravel uses a lot of symfony libraries and as you can see in techempower's benchmarks, symfony ranks very low (last to say the least). You can even find the laravel benchmark to be almost at the bottom.
A lot of auto-loading is happening in the background, things you might not even need gets loaded. So technically because laravel is easy to use, it helps you build apps fast, it also makes it slow.
But I am not saying Laravel is bad, it is great, great at a lot of things. But if you expect a high surge of traffic you will need a lot more hardware just to handle the requests. It would cost you a lot more. But if you are filthy rich then you can achieve anything with Laravel. :D
The usual trade-off:
Easy = Slow, Hard = Fast
I would consider C or Java to have a hard learning curve and a hard maintainability but it ranks very high in web frameworks.
Though not too related. I'm just trying to prove the point of easy = slow
:
Ruby has a very good reputation in maintainability and the easiness to learn it but it is also considered to be the slowest among python and php as shown here.
Using btoa
with unescape
and encodeURIComponent
didn't work for me. Replacing all the special characters with XML/HTML entities and then converting to the base64 representation was the only way to solve this issue for me. Some code:
base64 = btoa(str.replace(/[\u00A0-\u2666]/g, function(c) {
return '&#' + c.charCodeAt(0) + ';';
}));
In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.
But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:
{ Id: 1,
name:'john',
phones:[{title:'home',number:111111,...},
{title:'office',number:22222,...}]
}
sends
{ Id: 1,
name:'john',
phones:[object object]
phones:[object object]
}
If you are new to React JS and using create-react-app cli command to create the application, then run the following NPM command to include the latest version of font-awesome.
npm install --save font-awesome
import font-awesome to your index.js file. Just add below line to your index.js file
import '../node_modules/font-awesome/css/font-awesome.min.css';
or
import 'font-awesome/css/font-awesome.min.css';
Don't forget to use className as attribute
render: function() {
return <div><i className="fa fa-spinner fa-spin">no spinner but why</i></div>;
}
Arrays.toString(int []) works for me.
var isProduction = (process.argv.indexOf("production")>-1);
CLI gulp production
calls my production task and sets a flag for any conditionals.
The man pages is the best source of information you can find... and is at your fingertips: man mkdir
yields this about -p
switch:
-p, --parents
no error if existing, make parent directories as needed
Use case example: Assume I want to create directories hello/goodbye
but none exist:
$mkdir hello/goodbye
mkdir:cannot create directory 'hello/goodbye': No such file or directory
$mkdir -p hello/goodbye
$
-p
created both, hello
and goodbye
This means that the command will create all the directories necessaries to fulfill your request, not returning any error in case that directory exists.
About rlidwka
, Google has a very good memory for acronyms :). My search returned this for example: http://www.cs.cmu.edu/~help/afs/afs_acls.html
Directory permissions
l (lookup)
Allows one to list the contents of a directory. It does not allow the reading of files.
i (insert)
Allows one to create new files in a directory or copy new files to a directory.
d (delete)
Allows one to remove files and sub-directories from a directory.
a (administer)
Allows one to change a directory's ACL. The owner of a directory can always change the ACL of a directory that s/he owns, along with the ACLs of any subdirectories in that directory.
File permissions
r (read)
Allows one to read the contents of file in the directory.
w (write)
Allows one to modify the contents of files in a directory and use chmod on them.
k (lock)
Allows programs to lock files in a directory.
Hence rlidwka
means: All permissions on.
It's worth mentioning, as @KeithThompson pointed out in the comments, that not all Unix systems support ACL. So probably the rlidwka
concept doesn't apply here.
In Linux adding these lines to my code helped me.

Go to prompt command and type "adb devices". If it is empty, then make sure you allowed for "MTP Transfer" or similar and you enabled debugging on your phone.
To enable debugging, follow this tutorial: https://www.kingoapp.com/root-tutorials/how-to-enable-usb-debugging-mode-on-android.htm
Then type "adb devices" again. If a device is listed in there, then it should work now.
This affects:
This is because Netbeans does not 'see' that tomcat is started, although it started just fine.
I have filed Bug #262749 with NetBeans.
In the server.xml
file, in the Connector
element for HTTP/1.1, add the following attribute: server="Apache-Coyote/1.1"
.
Example:
<Connector
connectionTimeout="20000"
port="8080"
protocol="HTTP/1.1"
redirectPort="8443"
server="Apache-Coyote/1.1"
/>
The reason for that is that prior to 8.5.3, the default was to set the server header as Apache-Coyote/1.1
, while since 8.5.3 this default has now been changed to blank. Apparently Netbeans checks on this header.
Maybe in the future we can expect a fix in netbeans addressing this issue.
I was able to trace it back to a change in documentation.
"Overrides the Server header for the http response. If set, the value for this attribute overrides any Server header set by a web application. If not set, any value specified by the application is used. If the application does not specify a value then no Server header is set."
"Overrides the Server header for the http response. If set, the value for this attribute overrides the Tomcat default and any Server header set by a web application. If not set, any value specified by the application is used. If the application does not specify a value then Apache-Coyote/1.1 is used. Unless you are paranoid, you won't need this feature."
That explains the need for explicitly adding the server attribute since version 8.5.3.

I have a "last_password_change" column in my database that stores the date and time when the password was last changed. I also store the date/time of issue in the JWT. When validating a token, I check if the password has been changed after the token was issued and if it was the token is rejected even though it hasn't expired yet.
you can use map function. this is worked for me.
db.Sensors
.findAll({
where: { nodeid: node.nodeid }

response.json( rows )

Yes the culprit is definitely word-wrapping. When I tested your two programs, NetBeans IDE 8.2 gave me the following result.
Looking at your code closely you have used a line break at the end of first loop. But you didn't use any line break in second loop. So you are going to print a word with 1000 characters in the second loop. That causes a word-wrapping problem. If we use a non-word character " " after B, it takes only 5.35 seconds to compile the program. And If we use a line break in the second loop after passing 100 values or 50 values, it takes only 8.56 seconds and 7.05 seconds respectively.
Random r = new Random();
for (int i = 0; i < 1000; i++) {
for (int j = 0; j < 1000; j++) {
if(r.nextInt(4) == 0) {
System.out.print("O");
} else {
System.out.print("B");
}
if(j%100==0){ //Adding a line break in second loop
System.out.println();
}
}
System.out.println("");
}
Another advice is that to change settings of NetBeans IDE. First of all, go to NetBeans Tools and click Options. After that click Editor and go to Formatting tab. Then select Anywhere in Line Wrap Option. It will take almost 6.24% less time to compile the program.
just vars(obj)
, it will state the whole values of the object
>>> obj_attrs = vars(obj)
>>> obj_attrs
{'_file_data_cache': <FileData: Data>,
'_state': <django.db.models.base.ModelState at 0x7f5c6733bad0>,
'aggregator_id': 24,
'amount': 5.0,
'biller_id': 23,
'datetime': datetime.datetime(2018, 1, 31, 18, 43, 58, 933277, tzinfo=<UTC>),
'file_data_id': 797719,
}
You can add this also
>>> keys = obj_attrs.keys()
>>> temp = [obj_attrs.pop(key) if key.startswith('_') else None for key in keys]
>>> del temp
>>> obj_attrs
{
'aggregator_id': 24,
'amount': 5.0,
'biller_id': 23,
'datetime': datetime.datetime(2018, 1, 31, 18, 43, 58, 933277, tzinfo=<UTC>),
'file_data_id': 797719,
}
Here's a simple solution with lambdas:
root = Tk()
root.attributes("-fullscreen", True)
root.bind("<F11>", lambda event: root.attributes("-fullscreen",
not root.attributes("-fullscreen")))
root.bind("<Escape>", lambda event: root.attributes("-fullscreen", False))
root.mainloop()
This will make the screen exit fullscreen when escape is pressed, and toggle fullscreen when F11 is pressed.
An easy way to use the css3-mediaqueries-js is to include the following before the closing body tag:

@jeminar has the best solution above.
I cleaned it up a bit though.
I recommend adding this to a FunctionsArray module
isInitialised=false
is not needed because Booleans are false when createdOn Error GoTo 0
wrap and indent code inside error blocks similar to with
blocks for visibility. these methods should be avoided as much as possible but ... VBA ...Function isInitialised(ByRef a() As Variant) As Boolean

You need to use list-style: none;
<ul style="list-style: none;">
<li>...</li>

Try this:
window.onmousewheel = document.onmousewheel = null
window.ontouchmove = null
window.onwheel = null
Visual select the text, then U for uppercase or u for lowercase. To swap all casing in a visual selection, press ~ (tilde).
Without using a visual selection, gU<motion>
will make the characters in motion
uppercase, or use gu<motion>
for lowercase.
For more of these, see Section 3 in Vim's change.txt help file.
As per the official documents, it's not anymore advisable to use matrix class since it will be removed in the future.
https://numpy.org/doc/stable/reference/generated/numpy.matrix.html
As other answers already state that you can achieve all the operations with NumPy arrays.
Actually, the best solution for this question is to use checkout
commend
git checkout <branch> <path1>,<path2> ..
For example, assume you are in master, you want to the changes from dev1 on project1/Controller/WebController1.java
and project1/Service/WebService1.java
, you can use this:
git checkout dev1 project1/Controller/WebController1.java project1/Service/WebService1.java
That means the master branch only updates from dev1 on those two paths.
for
-loopA traditional for
-loop has three components :
These three components are seperated from each other by a ;
symbol. Content for each of these three components is optional, which means that the following is the most minimal for
-loop possible :
for (;;) {
// Do stuff
}
Of course, you will need to include an if(condition === true) { break; }
or an if(condition === true) { return; }
somewhere inside that for
-loop to get it to stop running.
Usually, though, the initialization is used to declare an index, the condition is used to compare that index with a minimum or maximum value, and the afterthought is used to increment the index :
for (var i = 0, length = 10; i < length; i++) {
console.log(i);
}
for
-loop to loop through an arrayThe traditional way to loop through an array, is this :
for (var i = 0, length = myArray.length; i < length; i++) {
console.log(myArray[i]);
}
Or, if you prefer to loop backwards, you do this :
for (var i = myArray.length - 1; i > -1; i--) {
console.log(myArray[i]);
}
There are, however, many variations possible, like eg. this one :
for (var key = 0, value = myArray[key], var length = myArray.length; key < length; value = myArray[++key]) {
console.log(value);
}
... or this one ...
var i = 0, length = myArray.length;
for (; i < length;) {
console.log(myArray[i]);
i++;
}
... or this one :
var key = 0, value;
for (; value = myArray[key++];){
console.log(value);
}
Whichever works best is largely a matter of both personal taste and the specific use case you're implementing.
Note :Each of these variations is supported by all browsers, including véry old ones!
while
-loopOne alternative to a for
-loop is a while
-loop. To loop through an array, you could do this :
var key = 0;
while(value = myArray[key++]){
console.log(value);
}
Note :
Like traditional for
-loops, while
-loops are supported by even the oldest of browsers.
Also, every while loop can be rewritten as a for
-loop. For example, the while
-loop hereabove behaves the exact same way as this for
-loop :
for(var key = 0;value = myArray[key++];){
console.log(value);
}
for...in
and for...of
In JavaScript, you can also do this :
for (i in myArray) {
console.log(myArray[i]);
}
This should be used with care, however, as it doesn't behave the same as a traditonal for
-loop in all cases, and there are potential side-effects that need to be considered. See Why is using "for...in" with array iteration a bad idea? for more details.
As an alternative to for...in
, there's now also for for...of
. The following example shows the difference between a for...of
loop and a for...in
loop :
var myArray = [3, 5, 7];
myArray.foo = "hello";
for (var i in myArray) {
console.log(i); // logs 0, 1, 2, "foo"
}
for (var i of myArray) {
console.log(i); // logs 3, 5, 7
}
Note :
You also need to consider that no version of Internet Explorer supports for...of
(Edge 12+ does) and that for...in
requires at least IE10.
Array.prototype.forEach()
An alternative to For
-loops is Array.prototype.forEach()
, which uses the following syntax :
myArray.forEach(function(value, key, myArray) {
console.log(value);
});
Note :
Array.prototype.forEach()
is supported by all modern browsers, as well as IE9+.
jQuery.each()
Additionally to the four other options mentioned, jQuery also had its own foreach
variation.
It uses the following syntax :
$.each(myArray, function(key, value) {
console.log(value);
});
The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0
):
ffmpeg -i input.mov -q:v 0 output.mp4
yes, there is:
object[] x = new object[2];
x[0] = new { firstName = "john", lastName = "walter" };
x[1] = new { brand = "BMW" };
you were practically there, just the declaration of the anonymous types was a little off.
If you want a single JavaScript object such as the following:
{ uniqueIDofSelect: "uniqueID", optionValue: "2" }
(where option 2, "Absent", is the current selection) then the following code should produce it:
var jsObj = null;
var status = document.getElementsByName("status")[0];
for (i = 0, i < status.options.length, ++i) {
if (options[i].selected ) {
jsObj = { uniqueIDofSelect: status.id, optionValue: options[i].value };
break;
}
}
If you want an array of all such objects (not just the selected one), use michael's code but swap out status.options[i].text
for status.id
.
If you want a string that contains a JSON representation of the selected object, use this instead:
var jsonStr = "";
var status = document.getElementsByName("status")[0];
for (i = 0, i < status.options.length, ++i) {
if (options[i].selected ) {
jsonStr = '{ '
+ '"uniqueIDofSelect" : '
+ '"' + status.id + '"'
+ ", "
+ '"optionValue" : '
+ '"'+ options[i].value + '"'
+ ' }';
break;
}
}
You have a numpy array of strings, not floats. This is what is meant by dtype('<U9')
-- a little endian encoded unicode string with up to 9 characters.
try:
return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))
However, you don't need numpy here at all. You can really just do:
return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)
Or if you're really set on using numpy.
return np.asarray(listOfEmb, dtype=float).mean()
it can also be achieved with below code
import re
text = 'how are u? umberella u! u. U. U@ U# u '
print (re.sub (r'[uU] ( [^a-z] )', r' you\1 ', text))
or
print (re.sub (r'[uU] ( [\s!,.?@#] )', r' you\1 ', text))
UPDATE tablename SET fieldname = CONCAT("test", fieldname) [WHERE ...]
... You can then use copy()
to duplicate a PHP file, although this sounds incredibly inefficient.
I want to point out one behavior of BackgroundWorker class that wasn't mentioned yet. You can make a normal Thread to run in background by setting the Thread.IsBackground property.
Background threads are identical to foreground threads, except that background threads do not prevent a process from terminating. [1]
You can test this behavoir by calling the following method in the constructor of your form window.
void TestBackgroundThread()
{
var thread = new Thread((ThreadStart)delegate()
{
long count = 0;
while (true)
{
count++;
Debug.WriteLine("Thread loop count: " + count);
}
});
// Choose one option:
thread.IsBackground = true; // <--- This will make the thread run in background
thread.IsBackground = false; // <--- This will delay program termination
thread.Start();
}
When the IsBackground property is set to true and you close the window, then your application will terminate normaly.
But when the IsBackground property is set to false (by default) and you close the window, then just the window will disapear but the process will still keep running.
The BackgroundWorker class utilize a Thread that runs in the background.

This is just some additional information that might help anyone. I want to make it abundantly clear that what I am describing here is possibly:
I am not a DBA, but every time I find myself setting up a SQL Server (Express or Full) for testing or what not I run into the connectivity issue. The solution I am describing is more for the person who is just trying to get their job done - consult someone who is knowledgeable in this field when setting up a production server.
For SQL Server 2008 R2 this is what I end up doing:
Usually after I do what I mentioned above I don't have a problem anymore. Here is a screenshot of what to look for - for that last step:

If you use
ssh [email protected] "~/tools/run_pvt.pl $BUILD_NUMBER"
instead of
ssh [email protected] '~/tools/run_pvt.pl $BUILD_NUMBER'
your shell will interpolate the $BUILD_NUMBER
before sending the command string to the remote host.
Looks like python requests does not handle extremely large multi-part files.
The documentation recommends you look into requests-toolbelt
.
Here's the pertinent page from their documentation.
SELECT TABLE_NAME AS "Table Name",
table_rows AS "Quant of Rows", ROUND( (
data_length + index_length
) /1024, 2 ) AS "Total Size Kb"
FROM information_schema.TABLES
WHERE information_schema.TABLES.table_schema = 'YOUR SCHEMA NAME/DATABASE NAME HERE'
LIMIT 0 , 30
You can get schema name from "information_schema" -> SCHEMATA table -> "SCHEMA_NAME" column
Additional You can get size of the mysql databases as following.
SELECT table_schema "DB Name",
Round(Sum(data_length + index_length) / 1024 / 1024, 1) "DB Size in MB"
FROM information_schema.tables
GROUP BY table_schema;
Result
DB Name | DB Size in MB
mydatabase_wrdp 39.1
information_schema 0.0

In SQL Server 2016 the wizard is a separate app. (Important: Excel wizard is only available in the 32-bit version of the wizard!). Use the MSDN page for instructions:
On the Start menu, point to All Programs, point toMicrosoft SQL Server , and then click Import and Export Data.
—or—
In SQL Server Data Tools (SSDT), right-click the SSIS Packages folder, and then click SSIS Import and Export Wizard.
—or—
In SQL Server Data Tools (SSDT), on the Project menu, click SSIS Import and Export Wizard.
—or—
In SQL Server Management Studio, connect to the Database Engine server type, expand Databases, right-click a database, point to Tasks, and then click Import Data or Export data.
—or—
In a command prompt window, run DTSWizard.exe, located in C:\Program Files\Microsoft SQL Server\100\DTS\Binn.

For exemple. You can insert the (select ... from ... where) wherever you want it will be replaced by the corresponding data.
I know that the others exemple (even if each of them are really great :) ) are a bit complicated to understand for the newbies (like me :p) so i hope this "simple" exemple will help some of you guys :)
You can get equal height columns in CSS by applying bottom padding of a large amount, bottom negative margin of the same amount and surrounding the columns with a div that has overflow hidden. Vertically centering the text is a little trickier but this should help you on the way.

I think it worth mentioning that the previous answer by streetpc has invalid html, the doctype is XHTML and there are single quotes around the attributes. Also worth noting is that you dont need an extra element with clear
on in order to clear the internal floats of the container. If you use overflow hidden this clears the floats in all non-IE browsers and then just adding something to give hasLayout such as width or zoom:1 will cause IE to clear its internal floats.
I have tested this in all modern browsers FF3+ Opera9+ Chrome Safari 3+ and IE6/7/8. It may seem like an ugly trick but it works well and I use it in production a lot.
I hope this helps.
For the legend, you can use this
plt.setp(g._legend.get_title(), fontsize=20)
Where g is your facetgrid object returned after you call the function making it.
HTML + JQuery: A link that submits a hidden form with POST.
Since I spent a lot of time to understand all these answers, and since all of them have some interesting details, here is the combined version that finally worked for me and which I prefer for its simplicity.
My approach is again to create a hidden form and to submit it by clicking a link somewhere else in the page. It doesn't matter where in the body of the page the form will be placed.
The code for the form:
<form id="myHiddenFormId" action="myAction.php" method="post" style="display: none">
<input type="hidden" name="myParameterName" value="myParameterValue">
</form>
Description:
The display: none
hides the form. You can alternatively put it in a div or another element and set the display: none
on the element.
The type="hidden"
will create an fild that will not be shown but its data will be transmitted to the action eitherways (see W3C). I understand that this is the simplest input type.
The code for the link:
<a href="" onclick="$('#myHiddenFormId').submit(); return false;" title="My link title">My link text</a>
Description:
The empty href
just targets the same page. But it doesn't really matter in this case since the return false
will stop the browser from following the link. You may want to change this behavior of course. In my specific case, the action contained a redirection at the end.
The onclick
was used to avoid using href="javascript:..."
as noted by mplungjan. The $('#myHiddenFormId').submit();
was used to submit the form (instead of defining a function, since the code is very small).
This link will look exactly like any other <a>
element. You can actually use any other element instead of the <a>
(for example a <span>
or an image).
The C Programming Language (K&R) would have you check for null == ptr to avoid an accidental assignment.
You can use \n
for new line and \t
for tabs. Also, extra spaces/tabs are just copied the way you write them in Strings.xml
so just give a couple of spaces where ever you want them.
A better way to reach this would probably be using padding/margin in your view xml and splitting up your long text in different strings in your string.xml
Yes; change your where to be:
where T:BaseFruit, new()
However, this only works with parameterless constructors. You'll have to have some other means of setting your property (setting the property itself or something similar).
now you can use rgba in CSS properties like this:
.class {
background: rgba(0,0,0,0.5);
}
0.5 is the transparency, change the values according to your design.

Following are few options available to change Heap Size.
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size

Yes, it is not required and is usually omitted. It might be required for accessing variables after they have been overridden in the scope though:
Person::Person() {
int age;
this->age = 1;
}
Also, this:
Person::Person(int _age) {
age = _age;
}
It is pretty bad style; if you need an initializer with the same name use this notation:
Person::Person(int age) : age(age) {}

JSONObject jsonObject = new JSONObject (YOUR_JSON_STRING);

I am late to the part but I found a nicer way to do this than the answer posted above. Instead of assigning a variable to hold the value of the service variable, I created a function attached to the scope, that returns the service variable.
controller
$scope.foo = function(){
return aService.foo;
}
I think this will do what you want. My controller keeps checking the value of my service with this implementation. Honestly, this is much simpler than the selected answer.
public <E> List<E> collectionToList(Collection<E> collection)
{
return (collection instanceof List) ? (List<E>) collection : new ArrayList<E>(collection);
}
Use the above method for converting the collection to list
I added .table-responsive
to the table and it worked. From the docs
Create responsive tables by wrapping any .table with .table-responsive{-sm|-md|-lg|-xl}, making the table scroll horizontally at each max-width breakpoint of up to (but not including) 576px, 768px, 992px, and 1120px, respectively.
The following code works as a count-up timer. It's pure JavaScript code which shows hour:minute:second
. It also has a STOP button:
var timerVar = setInterval(countTimer, 1000);
var totalSeconds = 0;
function countTimer() {
++totalSeconds;
var hour = Math.floor(totalSeconds /3600);
var minute = Math.floor((totalSeconds - hour*3600)/60);
var seconds = totalSeconds - (hour*3600 + minute*60);
if(hour < 10)
hour = "0"+hour;
if(minute < 10)
minute = "0"+minute;
if(seconds < 10)
seconds = "0"+seconds;
document.getElementById("timer").innerHTML = hour + ":" + minute + ":" + seconds;
}

<div id="timer"></div>
<div id ="stop_timer" onclick="clearInterval(timerVar)">Stop time</div>

If you're still getting an error check your Antivirus/Firewall is not blocking Xampp or port 443.
That's your jQuery API problem, not your script. There is not much to worry about.

If is ok for you to index the array you can do this:
<form>
<input type="text" class="form-control" placeholder="Titel" name="levels[0][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[0][build_time]">
<input type="text" class="form-control" placeholder="Titel" name="levels[1][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[1][build_time]">
<input type="text" class="form-control" placeholder="Titel" name="levels[2][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[2][build_time]">
</form>
... to achieve that:
[levels] => Array (
[0] => Array (
[level] => 1
[build_time] => 2
)
[1] => Array (
[level] => 234
[build_time] => 456
)
[2] => Array (
[level] => 111
[build_time] => 222
)
)
But if you remove one pair of inputs (dynamically, I suppose) from the middle of the form then you'll get holes in your array, unless you update the input names...
Bootstrap 3 and Bootstrap 4 docs refer two events you can use.
hide.bs.modal: This event is fired immediately when the hide instance method has been called.
hidden.bs.modal: This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
And provide an example on how to use them:
$('#myModal').on('hidden.bs.modal', function () {
// do something…
})
Bootstrap's documentation refers two events you can use.

I threw CMS's excellent answer into a quick jQuery extension:
(function($, window) {
$.fn.replaceOptions = function(options) {
var self, $option;
this.empty();
self = this;
$.each(options, function(index, option) {
$option = $("<option></option>")
.attr("value", option.value)
.text(option.text);
self.append($option);
});
};
})(jQuery, window);
It expects an array of objects which contain "text" and "value" keys. So usage is as follows:
var options = [
{text: "one", value: 1},
{text: "two", value: 2}
];
$("#foo").replaceOptions(options);
You can use the following: File.exists()
When installing Python 3.4 the "Add python.exe to Path" came up unselected. Re-installed with this selected and problem resolved.
This will format column A as text, B as General, C as a number.

Columns(2).NumberFormat = "General"
Columns(3).NumberFormat = "0"
End Sub
Inside controller inject Request object. So if you want to access request body inside controller method 'foo' do the following:
public function foo(Request $request){
$bodyContent = $request->getContent();
}
The same origin policy is applicable only for browser side programming languages. So if you try to post to a different server than the origin server using JavaScript, then the same origin policy comes into play but if you post directly from the form i.e. the action points to a different server like:
<form action="http://someotherserver.com">
and there is no javascript involved in posting the form, then the same origin policy is not applicable.
See wikipedia for more information
Datatables supports HTML5 data-* attributes for this functionality.
It supports multiple columns in the sort order (it's 0-based)
<table data-order="[[ 1, 'desc' ], [2, 'asc' ]]">
<thead>
<tr>
<td>First</td>
<td>Another column</td>
<td>A third</td>
</tr>
</thead>
<tbody>
<tr>
<td>z</td>
<td>1</td>
<td>$%^&*</td>
</tr>
<tr>
<td>y</td>
<td>2</td>
<td>*$%^&</td>
</tr>
</tbody>
</table>
Now my jQuery is simply $('table').DataTables();
and I get my second and third columns sorted in desc / asc order.
Here's some other nice attributes for the <table>
that I find myself reusing:
data-page-length="-1"
will set the page length to All (pass 25 for page length 25)...
data-fixed-header="true"
... Make a guess
You can gtk-server for this. Gtk-server is a program that runs in background and provides text-based interface to allow other programs (including bash scripts) to control it. It has examples for Bash (http://www.gtk-server.org/demo-ipc.bash.txt, http://www.gtk-server.org/demo-fifo.bash.txt)
If table is without partition then code will be,
Insert into table table_name
select col_a,col_b,col_c from another_table(source table)
--here any condition can be applied such as limit, group by, order by etc...
If table is with partitions then code will be,
set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;
insert into table table_name
partition(partition_col1
, paritition_col2
)
select col_a,col_b,col_c,partition_col1,partition_col2
from another_table(source table)
--here any condition can be applied such as limit, group by, order by etc...
In all of the cases above, the variable is correctly set, but not correctly read! The right way is to use double quotes when referencing:
echo "$var"
This gives the expected value in all the examples given. Always quote variable references!
Why?
When a variable is unquoted, it will:
Undergo field splitting where the value is split into multiple words on whitespace (by default):
Before: /* Foobar is free software */
After: /*
, Foobar
, is
, free
, software
, */
Each of these words will undergo pathname expansion, where patterns are expanded into matching files:
Before: /*
After: /bin
, /boot
, /dev
, /etc
, /home
, ...
Finally, all the arguments are passed to echo, which writes them out separated by single spaces, giving
/bin /boot /dev /etc /home Foobar is free software Desktop/ Downloads/
instead of the variable's value.
When the variable is quoted it will:
This is why you should always quote all variable references, unless you specifically require word splitting and pathname expansion. Tools like shellcheck are there to help, and will warn about missing quotes in all the cases above.
There can be multiple reasons for this problem and these reasons are mainly in the resource or app level build.gradle file.
In my case, a view in the resource file didn't had the required dependency included in the build.gradle file.
So, make sure to include all the required dependencies in the build.gradle file.

Use some design patterns, you can mix UIWebView and WKWebView. The key point is to design a unique browser interface. But you should pay more attention to your app's current functionality, for example: if your app using NSURLProtocol to enhance network ability, using WKWebView you have no chance to do the same thing. Because NSURLProtocol only effects the current process, and WKWebView using muliti-process architecture, the networking staff is in a seperate process.
Use the C Standard Library function getchar()
instead as getch()
is not a standard function, being provided by Borland TURBO C for MS-DOS/Windows only.
printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");
getchar();
Here, getchar()
expects you to press the return key so the printf
statement should be press ENTER to continue
. Even if you press another key, you still need to press ENTER:
printf("Let the Battle Begin!\n");
printf("Press ENTER key to Continue\n");
getchar();
If you are using Windows then you can use getch()
printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");
getch();
//if you press any character it will continue ,
//but this is not a standard c function.
char ch;
printf("Let the Battle Begin!\n");
printf("Press ENTER key to Continue\n");
//here also if you press any other key will wait till pressing ENTER
scanf("%c",&ch); //works as getchar() but here extra variable is required.
That's the problem. I've outputted a bunch of information (including the HTML to build the login page itself). So how do I redirect the user from one page to the next?
This means your application design is pretty broken. You shouldn't be doing output while your business logic is running. Go an use a template engine (like Smarty) or quickfix it by using output buffering).
Another option (not a good one though!) would be outputting JavaScript to redirect:
<script type="text/javascript">location.href = 'newurl';</script>
I wanted to be able to extract a list of apps just as they appear in the start menu. Using the registry, I was getting entries that do not show up in the start menu.
I also wanted to find the exe path and to extract an icon to eventually make a nice looking launcher. Unfortunately, with the registry method this is kind of a hit and miss since my observations are that this information isn't reliably available.
My alternative is based around the shell:AppsFolder which you can access by running explorer.exe shell:appsFolder
and which lists all apps, including store apps, currently installed and available through the start menu. The issue is that this is a virtual folder that can't be accessed with System.IO.Directory
. Instead, you would have to use native shell32 commands. Fortunately, Microsoft published the Microsoft.WindowsAPICodePack-Shell on Nuget which is a wrapper for the aforementioned commands. Enough said, here's the code:
// GUID taken from https://docs.microsoft.com/en-us/windows/win32/shell/knownfolderid
var FOLDERID_AppsFolder = new Guid("{1e87508d-89c2-42f0-8a7e-645a0f50ca58}");
ShellObject appsFolder = (ShellObject)KnownFolderHelper.FromKnownFolderId(FOLDERID_AppsFolder);
foreach (var app in (IKnownFolder)appsFolder)
{
// The friendly app name
string name = app.Name;
// The ParsingName property is the AppUserModelID
string appUserModelID = app.ParsingName; // or app.Properties.System.AppUserModel.ID
// You can even get the Jumbo icon in one shot
ImageSource icon = app.Thumbnail.ExtraLargeBitmapSource;
}
And that's all there is to it. You can also start the apps using
System.Diagnostics.Process.Start("explorer.exe", @" shell:appsFolder\" + appModelUserID);
This works for regular Win32 apps and UWP store apps. How about them apples.
Since you are interested in listing all installed apps, it is reasonable to expect that you might want to monitor for new apps or uninstalled apps as well, which you can do using the ShellObjectWatcher
:
ShellObjectWatcher sow = new ShellObjectWatcher(appsFolder, false);
sow.AllEvents += (s, e) => DoWhatever();
sow.Start();
Edit: One might also be interested in knowing that the AppUserMoedlID mentioned above is the unique ID Windows uses to group windows in the taskbar.

Unlike div
, p
1 which are Block Level elements which can take up margin
on all sides,span
2 cannot as it's an Inline element which takes up margins horizontally only.
From the specification:
Margin properties specify the width of the margin area of a box. The 'margin' shorthand property sets the margin for all four sides while the other margin properties only set their respective side. These properties apply to all elements, but vertical margins will not have any effect on non-replaced inline elements.
Demo 1 (Vertical margin
not applied as span
is an inline
element)
Solution? Make your span
element, display: inline-block;
or display: block;
.
Would suggest you to use display: inline-block;
as it will be inline
as well as block
. Making it block
only will result in your element to render on another line, as block
level elements take 100%
of horizontal space on the page, unless they are made inline-block
or they are floated
to left
or right
.

2. Inline Elements - MDN Resource
Just in case anyone is having the same problem... I was getting this error, and it turned out to be my <Application.Resources>
in my App.xaml file. I had a resource outside my resource dictionary tags, and that caused this error.
Had the same problem. Since you can still get data using the .data() method, you only have to figure out a way to write to the elements. This is the helper method I use. Like most people have said, you will have to use .attr. I have it replacing any _ with - as I know it does that. I'm not aware of any other characters it replaces...however I have not researched that.
function ExtendElementData(element, object){
//element is what you want to set data on
//object is a hash/js-object
var keys = Object.keys(object);
for (var i = 0; i < keys.length; i++){
var key = keys[i];
$(element).attr('data-'+key.replace("_", "-"), object[key]);
}
}
EDIT: 5/1/2017
I found there were still instances where you could not get the correct data using built in methods so what I use now is as follows:
function setDomData(element, object){
//object is a hash
var keys = Object.keys(object);
for (var i = 0; i < keys.length; i++){
var key = keys[i];
$(element).attr('data-'+key.replace("_", "-"), object[key]);
}
};
function getDomData(element, key){
var domObject = $(element).get(0);
var attKeys = Object.keys(domObject.attributes);
var values = null;
if (key != null){
values = $(element).attr('data-' + key);
} else {
values = {};
var keys = [];
for (var i = 0; i < attKeys.length; i++) {
keys.push(domObject.attributes[attKeys[i]]);
}
for (var i = 0; i < keys.length; i++){
if(!keys[i].match(/data-.*/)){
values[keys[i]] = $(element).attr(keys[i]);
}
}
}
return values;
};

You first must install python. Mac comes with python 2.7 installed to install Python 3 you can follow this tutorial: http://docs.python-guide.org/en/latest/starting/install3/osx/.
To run the program you can then copy and paste in this code:
python /Users/luca/Documents/python/gameover.py
Or you can go to the directory of the file with cd
followed by the folder. When you are in the folder you can then python YourFile.py

Ok maybe this one should solve your problem. Note that each time you make a change you call the change() method that releases the wait.
Integer any = new Integer(0);
public synchronized boolean waitTillChange() {
any.wait();
return true;
}
public synchronized void change() {
any.notify();
}
Your function would work like this:
CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS
$$
BEGIN
RETURN QUERY EXECUTE '

SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;
END
$$ LANGUAGE plpgsql;
Call:
SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)
You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.
The aggregate function count()
returns bigint
, but you had rowcount
defined as integer
, so you need an explicit cast ::int
to make this work
I use dollar quoting to avoid quoting hell.
However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.
Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)
The query itself seems rather odd, btw. But that's beside the point here.
Use the Array#join
method (the argument to join
is what to insert between the strings - in this case a space):
@arr.join(" ")
I faced with the same issue. I just added credentials config:
aws_access_key_id = your_aws_access_key_id
aws_secret_access_key = your_aws_secret_access_key
into "~/.aws/credentials" + restart terminal for default profile.
In the case of multi profiles --profile arg needs to be added:
aws s3 sync ./localDir s3://bucketName --profile=${PROFILE_NAME}
where PROFILE_NAME:
.bash_profile ( or .bashrc) -> export PROFILE_NAME="yourProfileName"
More info about how to config credentials and multi profiles can be found here
Stumbled across this answer and I actually wanted BOTH groups (data containing that one user and data containing everything but that one user). Not necessary for the specifics of this post, but I thought I would add in case someone was googling the same issue as me.
df <- data.frame(
ran_data1=rnorm(125),
ran_data2=rnorm(125),
g=rep(factor(LETTERS[1:5]), 25)
)
test_x = split(df,df$g)[['A']]
test_y = split(df,df$g!='A')[['TRUE']]
Here's what it looks like:
head(test_x)
x y g
1 1.1362198 1.2969541 A
6 0.5510307 -0.2512449 A

Use for of loop instead which is part of ES2015 release. Unlike forEach, we can use return, break and continue. See https://hacks.mozilla.org/2015/04/es6-in-depth-iterators-and-the-for-of-loop/
let arr = [1,2,3,4,5];
for (let ele of arr) {
if (ele > 3) break;
console.log(ele);
}
PuTTY can't find where your X server is, because you didn't tell it. (ssh on Linux doesn't have this problem because it runs under X so it just uses that one.) Fill in the blank box after "X display location" with your Xming server's address.
Alternatively, try MobaXterm. It has an X server builtin.
In case you have a BottomBar:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
if (mBottomBar.getCurrentTabId() == R.id.tab_more) {
getMenuInflater().inflate(R.menu.more_menu, menu);
}
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.preferences:
startActivity(new Intent(this, PreferenceActivity.class));
break;
}
return super.onOptionsItemSelected(item);
}
Then you just need to call:
@Override
public void onBottomBarClick(int tabId) {
supportInvalidateOptionsMenu();
}
Let's say you have a master
branch with files/directories:
> git branch
master
> ls -la # (files and dirs which you may keep in master)
.git
directory1
directory2
file_1
..
file_n
git checkout —orphan new_branch_name
ls -la |awk '{print $9}' |grep -v git |xargs -I _ rm -rf ./_
git rm -rf .
touch new_file
git add new_file
git commit -m 'added first file in the new branch'
git push origin new_branch_name
In step 2, we simply remove all the files locally to avoid confusion with the files on your new branch and those ones you keep in master
branch.
Then, we unlink all those files in step 3. Finally, step 4 and after are working with our new empty branch.
Once you're done, you can easily switch between your branches:
git checkout master
git checkout new_branch
to get every unique value from your customer table, use
SELECT DISTINCT CName FROM customertable;
more in-depth of w3schools: https://www.w3schools.com/sql/sql_distinct.asp
For example : a = "One Two Three"
1.9.2-p290 > a = "One Two Three"
=> "One Two Three"
1.9.2-p290 > a = a[1..-1]
=> "ne Two Three"
1.9.2-p290 > a = a[1..-1]
=> "e Two Three"
1.9.2-p290 > a = a[1..-1]
=> " Two Three"
1.9.2-p290 > a = a[1..-1]
=> "Two Three"
1.9.2-p290 > a = a[1..-1]
=> "wo Three"
In this way you can remove one by one first character of the string.
I just hit a problem with this. Mine was a fall off from changing the input
to a button
and I'd had a badly written />
tag terminator:
So I had:
<button name="submit_login" type="submit" class="login" />Login</button>
And have just amended it to:
<button name="submit_login" type="submit" class="login">Login</button>
Now works like a charm, always the annoying small things... HTH
here is my try to import database from cmd in xampp server the correct command for me is this you can change it with your requirements.and i also attached Errors that i face first time importing db from command line.you can see last command that i use and i paste it here also its working fro me.
mysql -h localhost -u root ovxsolut_windhs < C:\Users\eee\Downloads\ovxsolut_windhs.sql
I don't understand where the first "result with sample data" is coming from, but the problem in the console app is that you're using SelectMany
to look at each item in each group.
I think you just want:
List<ResultLine> result = Lines
.GroupBy(l => l.ProductCode)
.Select(cl => new ResultLine
{
ProductName = cl.First().Name,
Quantity = cl.Count().ToString(),
Price = cl.Sum(c => c.Price).ToString(),
}).ToList();
The use of First()
here to get the product name assumes that every product with the same product code has the same product name. As noted in comments, you could group by product name as well as product code, which will give the same results if the name is always the same for any given code, but apparently generates better SQL in EF.
I'd also suggest that you should change the Quantity
and Price
properties to be int
and decimal
types respectively - why use a string property for data which is clearly not textual?
Use the start
command with the /b
flag to run a command/application without opening a new window. For example, this runs dotnet run
in the background:
start /b dotnet run
You can pass parameters to the command/application too. For example, I'm starting 3 instances of this C# project, with parameter values of x
, y
, and z
:
CTRL + BREAK
In my experience, this stops all of the background commands/programs you have started in that cmd
instance.
According to the Microsoft docs:
CTRL+C handling is ignored unless the application enables CTRL+C processing. Use CTRL+BREAK to interrupt the application.

PyXML works well.
You didn't say what platform you're using, however if you're on Ubuntu you can get it with sudo apt-get install python-xml
. I'm sure other Linux distros have it as well.
If you're on a Mac, xpath is already installed but not immediately accessible. You can set PY_USE_XMLPLUS
in your environment or do it the Python way before you import xml.xpath:
if sys.platform.startswith('darwin'):
os.environ['PY_USE_XMLPLUS'] = '1'
In the worst case you may have to build it yourself. This package is no longer maintained but still builds fine and works with modern 2.x Pythons. Basic docs are here.
http://www.rodsdot.com/ee/cross_browser_clipboard_copy_with_pop_over_message.asp works with Flash 10 and all Flash enabled browsers.
Also ZeroClipboard has been updated to avoid the bug mentioned about page scrolling causing the Flash movie to no longer be in the correct place.
Since that method "Requires" the user to click a button to copy this is a convenience to the user and nothing nefarious is occurring.
Nothing here that is not covered. But would like to add my 2 cents. At times, I run a build and it changes lot of files and then I want to work on something, so this command really helps me a lot.
git update-index --assume-unchanged `git status | grep modified | sed 's|modified:||g'| xargs`
Hope someone else find it useful as well.
This works for me:
This is a criteria over two fields/columns (9 and 10), this filters rows with values >0 on column 9 and rows with values 4, 7, and 8 on column 10. lastrow
is the number of rows on the data section.
ActiveSheet.Range("$A$1:$O$" & lastrow).AutoFilter Field:=9, Criteria1:=">0", Operator:=xlAnd
ActiveSheet.Range("$A$1:$O$" & lastrow).AutoFilter Field:=10, Criteria1:=Arr("4","7","8"), Operator:=xlFilterValues
List<string> empnames = (from e in emplist select e.Enaame).ToList();
Or
string[] empnames = (from e in emplist select e.Enaame).ToArray();
Etc...
copy
module is a wrong tool for copying many files and/or directory structure, use synchronize
module instead which uses rsync
as backend. Mind you, it requires rsync
installed on both controller and target host. It's really powerful, check ansible documentation.
Example - copy files from build
directory (with subdirectories) of controller to /var/www/html
directory on target host:
synchronize:
src: ./my-static-web-page/build/
dest: /var/www/html
rsync_opts:
- "--chmod=D2755,F644" # copy from windows - force permissions
Follow command rename all files to sequence and also lowercase extension:
rename --counter-format 000001 --lower-case --keep-extension --expr='$_ = "$N" if @EXT' *
One thing to note is that ngModel is required for ngOptions to work... note the ng-model="blah"
which is saying "set $scope.blah to the selected value".
Try this:
<select ng-model="blah" ng-options="item.ID as item.Title for item in items"></select>
Here's more from AngularJS's documentation (if you haven't seen it):
for array data sources:
- label for value in array
- select as label for value in array
- label group by group for value in array = select as label group by group for value in array
for object data sources:
- label for (key , value) in object
- select as label for (key , value) in object
- label group by group for (key, value) in object
- select as label group by group for (key, value) in object
For some clarification on option tag values in AngularJS:
When you use ng-options
, the values of option tags written out by ng-options will always be the index of the array item the option tag relates to. This is because AngularJS actually allows you to select entire objects with select controls, and not just primitive types. For example:
app.controller('MainCtrl', function($scope) {
$scope.items = [
{ id: 1, name: 'foo' },
{ id: 2, name: 'bar' },
{ id: 3, name: 'blah' }
];
});
<div ng-controller="MainCtrl">
<select ng-model="selectedItem" ng-options="item as item.name for item in items"></select>
<pre>{{selectedItem | json}}</pre>
</div>
The above will allow you to select an entire object into $scope.selectedItem
directly. The point is, with AngularJS, you don't need to worry about what's in your option tag. Let AngularJS handle that; you should only care about what's in your model in your scope.
Here is a plunker demonstrating the behavior above, and showing the HTML written out
Dealing with the default option:
There are a few things I've failed to mention above relating to the default option.
Selecting the first option and removing the empty option:
You can do this by adding a simple ng-init
that sets the model (from ng-model
) to the first element in the items your repeating in ng-options
:
<select ng-init="foo = foo || items[0]" ng-model="foo" ng-options="item as item.name for item in items"></select>
Note: This could get a little crazy if foo
happens to be initialized properly to something "falsy". In that case, you'll want to handle the initialization of foo
in your controller, most likely.
Customizing the default option:
This is a little different; here all you need to do is add an option tag as a child of your select, with an empty value attribute, then customize its inner text:
<select ng-model="foo" ng-options="item as item.name for item in items">
<option value="">Nothing selected</option>
</select>
Note: In this case the "empty" option will stay there even after you select a different option. This isn't the case for the default behavior of selects under AngularJS.
A customized default option that hides after a selection is made:
If you wanted your customized default option to go away after you select a value, you can add an ng-hide attribute to your default option:
<select ng-model="foo" ng-options="item as item.name for item in items">
<option value="" ng-if="foo">Select something to remove me.</option>
</select>
The python 2.5 documentation explains it well.
Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.
If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is ordered first (for example, [1,2] < [1,2,3]).
Unfortunately that page seems to have disappeared in the documentation for more recent versions.
Just Go to
iOS Simulator -> Hardware -> Keyboard -> Uncheck the Connect Hardware Keyboard Option.
This will fix the issue.
Your MAC keyboard will not work after performing the above step, You have to use simulator keyboard.
Isn't the height of the text in pixels equal to the font size (in pts) if you define the font using context.font ?
<link rel="shortcut icon" type="image/x-icon" href="~/favicon.ico" />
_x000D_
This worked for me. If anyone is troubleshooting while reading this - I found issues when my favicon.ico was not nested in the root folder. I had mine in the Resources folder and was struggling at that point.
Try jcabi-xml, with a one liner:
Node node = new XMLDocument("<node>value</node>").node();
You can just use localStorage
and remember the date it was first created in session cookie
. When localStorage
"session" is older than the value of cookie then you may clear the localStorage
Cons of this is that someone can still read the data after the browser is closed so it's not a good solution if your data is private and confidental.
You can store your data to localStorage
for a couple of seconds and add event listener for a storage
event. This way you will know when any of the tabs wrote something to the localStorage
and you can copy its content to the sessionStorage
, then just clear the localStorage
You could add a span before the link with a specific class like so:
<div class="btn btn_red"><span class="icon"></span><a href="#">Crimson</a><span></span></div>
And then give that a specific width and a background image just like you are doing with the button itself.
.btn span.icon {
background: url(imgs/icon.png) no-repeat;
float: left;
width: 10px;
height: 40px;
}
I am no CSS guru but off the top of my head I think that should work.
With these two steps we can check if it LL(1) or not. Both of them have to be satisfied.
1.If we have the production:A->a1|a2|a3|a4|.....|an. Then,First(a(i)) intersection First(a(j)) must be phi(empty set)[a(i)-a subscript i.]
2.For every non terminal 'A',if First(A) contains epsilon Then First(A) intersection Follow(A) must be phi(empty set).
Git pull is actually a combo tool: it runs git fetch (getting the changes) and git merge (merging them with your current copy)
Are you sure you are on the correct branch?
White space is important, expr
expects its operands and operators as separate arguments. You also have to capture the output. Like this:
COUNT=$(expr $FIRSTV - $SECONDV)
but it's more common to use the builtin arithmetic expansion:
COUNT=$((FIRSTV - SECONDV))
Run
git remote -v
and check whether your origin's URL has your co-worker's username hardcoded in there. If so, substitute it with your own:
git remote set-url origin <url-with-your-username>
The push()
method adds new items to the end of an array, and returns the new length. Example:
var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.push("Kiwi");
// The result of fruits will be:
Banana, Orange, Apple, Mango, Kiwi
The exact answer to your question is already answered, but let's look at some other ways to add items to an array.
The unshift()
method adds new items to the beginning of an array, and returns the new length. Example:
var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.unshift("Lemon", "Pineapple");
// The result of fruits will be:
Lemon, Pineapple, Banana, Orange, Apple, Mango
And lastly, the concat()
method is used to join two or more arrays. Example:
var fruits = ["Banana", "Orange"];
var moreFruits = ["Apple", "Mango", "Lemon"];
var allFruits = fruits.concat(moreFruits);
// The values of the children array will be:
Banana, Orange, Apple, Mango, Lemon
public class ServiceA extends Service {
//....
public void showToast(final String message) {
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
@Override
public void run() {
Toast.makeText(getContext(), message, Toast.LENGTH_LONG).show();
}
});
}
//....
}
You can also put showToast
method in your Application class, and show toast from anywhere.
In my case, I was using a dependency scoped as <scope>test</scope>
. This made the class available at development time but, by at compile time, I got this message.
Turn the class scope for <scope>provided</scope>
solved the problem.
A three line solution, but works quite well:
int[] source_array = {0,1,2,3,4,5,6,7,8,9,10,11};
ArrayList<Integer> target_list = new ArrayList<Integer>();
for(int i = 0; i < source_array.length; i++){
target_list.add(random_array[i]);
}
I've got the same problem here. I have an UTF-8 Page an need to post to an ISO-8859-1 server.
Looks like IE can't handle ISO-8859-1. But it can handle ISO-8859-15.
<form accept-charset="ISO-8859-15">
...
</form>
So this worked for me, since ISO-8859-1 and ISO-8859-15 are almost the same.
Use is_same
:
#include <type_traits>
template <typename T>
void foo()
{
if (std::is_same<T, animal>::value) { /* ... */ } // optimizable...
}
Usually, that's a totally unworkable design, though, and you really want to specialize:
template <typename T> void foo() { /* generic implementation */ }
template <> void foo<animal>() { /* specific for T = animal */ }
Note also that it's unusual to have function templates with explicit (non-deduced) arguments. It's not unheard of, but often there are better approaches.
If you have Pillow
installed with scipy
and it is still giving you error then check your scipy
version because it has been removed from scipy since 1.3.0rc1
.
rather install scipy 1.1.0
by :
pip install scipy==1.1.0
check https://github.com/scipy/scipy/issues/6212
The method imread
in scipy.misc
requires the forked package of PIL
named Pillow
. If you are having problem installing the right version of PIL try using imread
in other packages:
from matplotlib.pyplot import imread
im = imread(image.png)
To read jpg
images without PIL
use:
import cv2 as cv
im = cv.imread(image.jpg)
You can try
from scipy.misc.pilutil import imread
instead of from scipy.misc import imread
Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.
You can't. They simply do not work that way. A drop down menu must have one of its options selected at all times.
You could (although I don't recommend it) watch for a change event and then use JS to delete the first option if it is blank.
I strongly suggest you to read this blog post which appeared on HackerNews recently: How HashMap works in Java
In short, the answer is
What will happen if two different HashMap key objects have same hashcode?
They will be stored in same bucket but no next node of linked list. And keys equals () method will be used to identify correct key value pair in HashMap.
SELECT pg_size_pretty(pg_database_size('name of database'));
Will give you the total size of a particular database however I don't think you can do all databases within a server.
However you could do this...
DO
$$
DECLARE
r RECORD;
db_size TEXT;
BEGIN
FOR r in
SELECT datname FROM pg_database
WHERE datistemplate = false
LOOP
db_size:= (SELECT pg_size_pretty(pg_database_size(r.datname)));
RAISE NOTICE 'Database:% , Size:%', r.datname , db_size;
END LOOP;
END;
$$
If you use UPPER(text)
, the like '%lah%'
will always return zero results. Use '%LAH%'
.
Yes you can change it. if you call VBscript function within Javascript.
Here is simple example
<script>
function alert_confirm(){
customMsgBox("This is my title","how are you?",64,0,0,0);
}
</script>
<script language="VBScript">
Function customMsgBox(tit,mess,icon,buts,defs,mode)
butVal = icon + buts + defs + mode
customMsgBox= MsgBox(mess,butVal,tit)
End Function
</script>
<html>
<body>
<a href="javascript:alert_confirm()">Alert</a>
</body>
</html>
It is a accepted standard to have content, layout and behavior separate. So window.onload() will be more suitable to use than <body onload="">
though both do the same work.
Oracle does support WITH.
It would look like this.
WITH emps as (SELECT * FROM Employees)
SELECT * FROM emps WHERE ID < 20
UNION ALL
SELECT * FROM emps where Sex = 'F'
@ysth WITH is hard to google because it's a common word typically excluded from searches.
You'd want to look at the SELECT docs to see how subquery factoring works.
I know this doesn't answer the OP but I'm cleaning up any confusion ysth may have started.
Webclient client = new Webclient();
string content = client.DownloadString(url);
Pass the URL of page who you want to get. You can parse the result using htmlagilitypack.
You can use TextWatcher for TextView, is more flexible than ClickLinstener (not best or worse, only more one way).
holder.bt_foo_ex.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// code during!
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
// code before!
}
@Override
public void afterTextChanged(Editable s) {
// code after!
}
});
You should create the media
dir appended to what getLocalPath()
returns.
SQL injection: when user has the chance to input something that could be part of the sql statement
For example:
String query = “INSERT INTO students VALUES(‘” + user + “‘)”
when user input “Robert’); DROP TABLE students; –” as the input, it causes SQL injection
How prepared statement prevents this?
String query = “INSERT INTO students VALUES(‘” + “:name” + “‘)”
parameters.addValue(“name”, user);
=> when user input again “Robert’); DROP TABLE students; –“, the input string is precompiled on the driver as literal values and I guess it may be casted like:
CAST(‘Robert’); DROP TABLE students; –‘ AS varchar(30))
So at the end, the string will be literally inserted as the name to the table.
http://blog.linguiming.com/index.php/2018/01/10/why-prepared-statement-avoids-sql-injection/
This is useful when you want to have a global variable. You define the global variables in some source file, and declare them extern in a header file so that any file that includes that header file will then see the same global variable.
Resorting to a PivotTable might not count as using formulas only but seems more practical that most other suggestions so far:
You can use the infoDictionary which gets the version details from info.plist of you app. This code works for swift 3. Just call this method and display the version in any preferred UI element.
Swift-3
func getVersion() -> String {
let dictionary = Bundle.main.infoDictionary!
let version = dictionary["CFBundleShortVersionString"] as! String
let build = dictionary["CFBundleVersion"] as! String
return "v\(version).\(build)"
}
I'm also running XP SP2, and this works perfectly (from the command line...):
start control schedtasks
You can achieve this with: EventTarget.dispatchEvent(event)
and by passing in a new KeyboardEvent as the event.
For example: element.dispatchEvent(new KeyboardEvent('keypress', {'key': 'a'}))
Working example:
// get the element in question_x000D_
const input = document.getElementsByTagName("input")[0];_x000D_
_x000D_
// focus on the input element_x000D_
input.focus();_x000D_
_x000D_
// add event listeners to the input element_x000D_
input.addEventListener('keypress', (event) => {_x000D_
console.log("You have pressed key: ", event.key);_x000D_
});_x000D_
_x000D_
input.addEventListener('keydown', (event) => {_x000D_

I had the exact same issue. If you are using a relative path os.path.dirname(path) will only return the relative path. os.path.realpath does the trick:
>>> import os
>>> f = open('file.txt')
>>> os.path.realpath(f.name)
One more point in addition to the above answers. When using a font inside a fragment, the typeface instantiation should be done in the onAttach method ( override ) as given below:
@Override
public void onAttach(Activity activity){
super.onAttach(activity);
Typeface tf = Typeface.createFromAsset(getApplicationContext().getAssets(),"fonts/fontname.ttf");
}
Reason:
There is a short span of time before a fragment is attached to an activity. If CreateFromAsset method is called before attaching fragment to an activity an error occurs.
I was having similar problems loading 3D models from S3 into a javascript 3D viewer (3D HOP), but strangely enough only with certain file types (.nxs).
What fixed it for me was changing AllowedHeader
from the default Authorization
to *
in the CORS config:
<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<MaxAgeSeconds>3000</MaxAgeSeconds>
<AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>
Date.parse
recognizes only specific formats, and you don't have the option of telling it what your input format is. In this case it thinks that the input is in the format mm/dd/yyyy
, so the result is wrong.
To fix this, you need either to parse the input yourself (e.g. with String.split
) and then manually construct a Date
object, or use a more full-featured library such as datejs.
Example for manual parsing:
var input = $('#' + controlName).val();
var parts = str.split("/");
var d1 = new Date(Number(parts[2]), Number(parts[1]) - 1, Number(parts[0]));
Example using date.js:
var input = $('#' + controlName).val();
var d1 = Date.parseExact(input, "d/M/yyyy");
Use data URL scheme: https://en.wikipedia.org/wiki/Data_URI_scheme
In this case you use that string directly in html : <img src="data:image/png;base64,iVBOR....">
Here is an answer that should work in all cases:
def is_empty(s):
"Check whether a string is empty"
return not s or not s.strip()
If the variable is None, it will stop at not s
and not evaluate further (since not None == True
). Apparently, the strip()
method takes care of the usual cases of tab, newline, etc.
There are multiple methods for handling this problem.
My advice is to use the powerful Windows freeware console application SendEmail.
sendEmail.exe -f [email protected] -o message-file=body.txt -u subject message -t [email protected] -a attachment.zip -s smtp.gmail.com:446 -xu gmail.login -xp gmail.password
Use <br/>
. For example:
Change log, upgrade version
Dependency | Old version | New version |
---------- | ----------- | -----------
Spring Boot | `1.3.5.RELEASE` | `1.4.3.RELEASE`
Gradle | `2.13` | `3.2.1`
Gradle plugin <br/>`com.gorylenko.gradle-git-properties` | `1.4.16` | `1.4.17`
`org.webjars:requirejs` | `2.2.0` | `2.3.2`
`org.webjars.npm:stompjs` | `2.3.3` | `2.3.3`
`org.webjars.bower:sockjs-client` | `1.1.0` | `1.1.1`
You can use for loop to untar multiple .tar.gz files to another folder. The following code will take /destination/folder/path as an argument to the script and untar all .tar.gz files present at the current location in /destination/folder/path.
if [ $# -ne 1 ];
then
echo "invalid argument/s"
echo "Usage: ./script-file-name.sh /target/directory"
exit 0
fi
for file in *.tar.gz
do
tar -zxvf "$file" --directory $1
done
Simple javascript solution for all browser:
setTimeout(function() {
$(".parent input").each(function(){
parent = $(this).parents(".parent");
$(this).clone().appendTo(parent);
$(this).attr("id","").attr("name","").hide();
});
}, 300 );
Clone input, reset attribute and hide original input. Timeout is needed for iPad
By encode, do you mean: Convert all applicable characters to HTML entities?
htmlspecialchars
or
htmlentities
You can also use strip_tags if you want to remove all HTML tags :
Note: this will NOT stop all XSS attacks
Here is what I use. It combined process enumeration to perform switching and mutex to safeguard from "active clickers":
public partial class App
{
[DllImport("user32")]
private static extern int OpenIcon(IntPtr hWnd);
[DllImport("user32.dll")]
private static extern bool SetForegroundWindow(IntPtr hWnd);
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
var p = Process
.GetProcessesByName(Process.GetCurrentProcess().ProcessName);
foreach (var t in p.Where(t => t.MainWindowHandle != IntPtr.Zero))
{
OpenIcon(t.MainWindowHandle);
SetForegroundWindow(t.MainWindowHandle);
Current.Shutdown();
return;
}
// there is a chance the user tries to click on the icon repeatedly
// and the process cannot be discovered yet
bool createdNew;
var mutex = new Mutex(true, "MyAwesomeApp",
out createdNew); // must be a variable, though it is unused -
// we just need a bit of time until the process shows up
if (!createdNew)
{
Current.Shutdown();
return;
}
new Bootstrapper().Run();
}
}
Unique Keys: The columns in which no two rows are similar
Primary Key: Collection of minimum number of columns which can uniquely identify every row in a table (i.e. no two rows are similar in all the columns constituting primary key). There can be more than one primary key in a table. If there exists a unique-key then it is primary key (not "the" primary key) in the table. If there does not exist a unique key then more than one column values will be required to identify a row like (first_name, last_name, father_name, mother_name) can in some tables constitute primary key.
Index: used to optimize the queries. If you are going to search or sort the results on basis of some column many times (eg. mostly people are going to search the students by name and not by their roll no.) then it can be optimized if the column values are all "indexed" for example with a binary tree algorithm.
In case anyone stumbles with this problem again, the accepted solution did work for older versions of ionic and app scripts, I had used it many times in the past, but last week, after I updated some stuff, it got broken again, and this fix wasn't working anymore as this was already solved on the current version of app-scripts, most of the info is referred on this post https://forum.ionicframework.com/t/ionic-cordova-run-android-livereload-cordova-not-available/116790/18 but I'll make it short here:
First make sure you have this versions on your system
cli packages: (xxxx\npm\node_modules)
@ionic/cli-utils : 1.19.2 ionic (Ionic CLI) : 3.20.0
global packages:
cordova (Cordova CLI) : not installed
local packages:
@ionic/app-scripts : 3.1.9 Cordova Platforms : android 7.0.0 Ionic Framework : ionic-angular 3.9.2
System:
Node : v10.1.0 npm : 5.6.0
An this on your package.json
"@angular/cli": "^6.0.3", "@ionic/app-scripts": "^3.1.9", "typescript": "~2.4.2"
Now remove your platform with ionic cordova platform rm what-ever Then DELETE the node_modules and plugins folder and MAKE SURE the platform was deleted inside the platforms folder.
Finally, run
npm install ionic cordova platform add what-ever ionic cordova run
And everything should be working again
Float has 32 bit (4 bytes) with 8 places accuracy. Double has 64 bit (8 bytes) with 16 places accuracy.
If you need better accuracy, use Double instead of Float.
Simple do this:
df = df.loc[:, ~df.columns.str.contains('^Unnamed')]
Actually, it is
private const int TheAnswer = 42;
At least if you look at the .NET library, which IMO is the best way to decide naming conventions - so your code doesn't look out of place.
The replacement with snprintf is NOT complete!
It covers only bases: 2, 8, 10, 16, whereas itoa works for bases between 2 and 36.
Since I was searching a replacement for base 32, I guess I'll have to code my own!
var list = new List<MyClass>();
var item = list.Find( x => x.GetId() == "TARGET_ID" );
or if there is only one and you want to enforce that something like SingleOrDefault
may be what you want
var item = list.SingleOrDefault( x => x.GetId() == "TARGET" );
if ( item == null )
throw new Exception();
Even if your data falls within your specified limits (e.g. c(0, 335)
), adding a geom_jitter()
statement could push some points outside those limits, producing the same error message.
library(ggplot2)
range(mtcars$hp)
#> [1] 52 335
# No jitter -- no error message
ggplot(mtcars, aes(mpg, hp)) +
geom_point() +
scale_y_continuous(limits=c(0,335))
# Jitter is too large -- this generates the error message
ggplot(mtcars, aes(mpg, hp)) +
geom_point() +
geom_jitter(position = position_jitter(w = 0.2, h = 0.2)) +
scale_y_continuous(limits=c(0,335))
#> Warning: Removed 1 rows containing missing values (geom_point).

I had this problem a couple hours ago when I exported my projects from Eclipse to Android Studio. Unfortunately, the top answers here didn't work for me.
Anyway, creating a new project instead of opening an old one did the trick for me as what Thomas Kaliakos mentioned on his comment here
I had to mess around with the project..and at some point it worked. I don't know how though. My guess would be that creating a new project and adding your source code would work every time. Sorry for not being very clear, but honestly I was surprized even myself that it worked. – Thomas Kaliakos Oct 15 '13 at 4:08

ECMA2017 onwards:
Object.values(obj)
will fetch you all the property values as an array.

foreach (DataGridViewRow row in dataGridView1.Rows)
{
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
String header = dataGridView1.Columns[i].HeaderText;
//String cellText = row.Cells[i].Text;
DataGridViewColumn column = dataGridView1.Columns[i]; // column[1] selects the required column
column.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells; // sets the AutoSizeMode of column defined in previous line
int colWidth = column.Width; // store columns width after auto resize
colWidth += 50; // add 30 pixels to what 'colWidth' already is
this.dataGridView1.Columns[i].Width = colWidth; // set the columns width to the value stored in 'colWidth'
}
}
Using a list comprehension:
from datetime import date, timedelta
d1 = date(2008,8,15)
d2 = date(2008,9,15)
# this will give you a list containing all of the dates
dd = [d1 + timedelta(days=x) for x in range((d2-d1).days + 1)]
for d in dd:
print d
# you can't join dates, so if you want to use join, you need to
# cast to a string in the list comprehension:
ddd = [str(d1 + timedelta(days=x)) for x in range((d2-d1).days + 1)]
# now you can join
print "\n".join(ddd)
The problem is somewhere else in your code, because this works:
string line("test\ttest2\ttest3");
vector<string> strs;
boost::split(strs,line,boost::is_any_of("\t"));
cout << "* size of the vector: " << strs.size() << endl;
for (size_t i = 0; i < strs.size(); i++)
cout << strs[i] << endl;
and testing your approach, which uses a vector iterator also works:
string line("test\ttest2\ttest3");
vector<string> strs;
boost::split(strs,line,boost::is_any_of("\t"));
cout << "* size of the vector: " << strs.size() << endl;
for (vector<string>::iterator it = strs.begin(); it != strs.end(); ++it)
{
cout << *it << endl;
}
Again, your problem is somewhere else. Maybe what you think is a \t
character on the string, isn't. I would fill the code with debugs, starting by monitoring the insertions on the vector to make sure everything is being inserted the way its supposed to be.
Output:
* size of the vector: 3
test
test2
test3
If you use jQuery you can write:

I've been trying to do this in Jupyter Lab so thought it might be useful to post the answer here. You can find the shortcuts in settings and also add your own, where a full list of the possible shortcuts can be found here.
For example, I added my own shortcut to run all cells. In Jupyter Lab, under Settings > Advanced Settings, select Keyboard Shortcuts, then add the following code to 'User Overrides':
{
"notebook:run-all-cells": {
"command": "notebook:run-all-cells",
"keys": [
"Shift Backspace"
],
"selector": ".jp-Notebook.jp-mod-editMode"
}
}
Here, Shift + Backspace will run all cells in the notebook.
You can add parameter columns or use dict
with key which is converted to column name:
np.random.seed(123)
e = np.random.normal(size=10)
dataframe=pd.DataFrame(e, columns=['a'])
print (dataframe)
a
0 -1.085631
1 0.997345
2 0.282978

6 -2.426679
7 -0.428913
8 1.265936
9 -0.866740
e_dataframe=pd.DataFrame({'a':e})
print (e_dataframe)

To provide a differing response, I'm running OS X and Xcode on a virtualised (VMware) machine on Linux. CPU is a Core2Quad (Q8800), and it is perfectly fast. I found a prebuilt VM online (I'll leave it to you to find) Xcode/iPhone development works perfectly, as does debugging via USB to the phone itself.
It actually surprised me a lot - but I've had no issues at all.
well for one thing, since i dont really understand what you want to do, the lines
int roundUp = roundDown + multiple;
int roundCalc = roundUp;
return (roundCalc);
could definitely be shortened to
int roundUp = roundDown + multiple;
return roundUp;
Steps to reproduce can be simplified to this:
var contextOne = new EntityContext();
var contextTwo = new EntityContext();
var user = contextOne.Users.FirstOrDefault();
var group = new Group();
group.User = user;
contextTwo.Groups.Add(group);
contextTwo.SaveChanges();
Code without error:
var context = new EntityContext();
var user = context.Users.FirstOrDefault();
var group = new Group();
group.User = user; // Be careful when you set entity properties.
// Be sure that all objects came from the same context
context.Groups.Add(group);
context.SaveChanges();
Using only one EntityContext
can solve this. Refer to other answers for other solutions.
Using RandomAccessFile
would be simple and handy.
RandomAccessFile f = new RandomAccessFile(filepath, "r");
byte[] bytes = new byte[(int) f.length()];
f.read(bytes);
f.close();
All proposed solutions didn't work for me but the closest one was from @Rishii.
I'm using AngularJS 1.4.4 and UI Bootstrap 0.13.3.

var dateFormat = 'yyyy-MM-dd';
ngModel.$parsers.push(function(viewValue) {
return dateFilter(viewValue, dateFormat);
});
ngModel.$validators.date = function (modelValue, viewValue) {
var value = modelValue || viewValue;
if (!attrs.ngRequired && !value) {
return true;
}
if (angular.isNumber(value)) {
value = new Date(value);
}
if (!value) {
return true;
}
else if (angular.isDate(value) && !isNaN(value)) {
return true;
}
else if (angular.isString(value)) {
var date = dateParser.parse(value, dateFormat);
return !isNaN(date);
}
else {
return false;

}
};
}])
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8"))); //remove the parameter UTF-8 if you don't want to specify the Encoding type.
this works well for me even though the XML structure is complex.
And please make sure your xmlString is valid for XML, notice the escape character should be added "\" at the front.
The main problem might not come from the attributes.
Your problem is not with the match / replacement, but that String is immutable, you need to assign the result:
str = str.replaceAll(",","."); // or "\\.", it doesn't matter...
(
with the pattern
\(
. Regex.Escape
or Java's Pattern.quote
\Q
and \E
, with literal text between them.(
literally, and require \(
for capturing groups.There are many way to do the string aggregation, but the easiest is a user defined function. Try this for a way that does not require a function. As a note, there is no simple way without the function.
This is the shortest route without a custom function: (it uses the ROW_NUMBER() and SYS_CONNECT_BY_PATH functions )
SELECT questionid,
LTRIM(MAX(SYS_CONNECT_BY_PATH(elementid,','))
KEEP (DENSE_RANK LAST ORDER BY curr),',') AS elements
FROM (SELECT questionid,
elementid,
ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) AS curr,
ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) -1 AS prev
FROM emp)
GROUP BY questionid
CONNECT BY prev = PRIOR curr AND questionid = PRIOR questionid
START WITH curr = 1;
Are you using Git-Bash
in Windows? I was getting the same error until I tried PowerShell
and magically this error disappeared.
string mac = "";
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
if (nic.OperationalStatus == OperationalStatus.Up && (!nic.Description.Contains("Virtual") && !nic.Description.Contains("Pseudo")))
{
if (nic.GetPhysicalAddress().ToString() != "")
{
mac = nic.GetPhysicalAddress().ToString();
}
}
}
MessageBox.Show(mac);
Other way with Git Bash:
stopProcessByPortNumber() {
port=":${1}"
portStrLine="$(netstat -ano | findstr LISTENING | findstr $port)"
processId="$(grep -oP '(\d+)(?!.*\d)' <<< $portStrLine)"
echo $processId
taskkill -PID $processId -F
}
I am adding this because all other answers I tried fell short one way or another. The following method can handle large files, arbitrary long lines, as well as empty lines. It has been tested with actual content and will strip out newline character from the output.
- (NSString*)readLineFromFile:(FILE *)file
{
char buffer[4096];
NSMutableString *result = [NSMutableString stringWithCapacity:1000];
int charsRead;
do {
if(fscanf(file, "%4095[^\r\n]%n%*[\n\r]", buffer, &charsRead) == 1) {
[result appendFormat:@"%s", buffer];
}
else {
break;
}
} while(charsRead == 4095);
return result.length ? result : nil;
}

We can read properties file in spring boot using 3 way
1. Read value from application.properties Using @Value
map key as
public class EmailService {
@Value("${email.username}")
private String username;
}
2. Read value from application.properties Using @ConfigurationProperties
In this we will map prefix of key using ConfigurationProperties and key name is same as field of class
@Component
@ConfigurationProperties("email")
public class EmailConfig {
private String username;
}
3. Read application.properties Using using Environment object
public class EmailController {
@Autowired
private Environment env;
@GetMapping("/sendmail")
public void sendMail(){
System.out.println("reading value from application properties file using Environment ");
System.out.println("username ="+ env.getProperty("email.username"));
System.out.println("pwd ="+ env.getProperty("email.pwd"));
}

Another approach is keep that element, change the text, then append that element back
const star_icon = $(li).find('.stars svg')
$(li).find('.stars').text(repo.stargazers_count).append(star_icon)
Use \n
for a line break and \t
if you want to insert a tab.
You can also use some XML tags for basic formatting: <b>
for bold text, <i>
for italics, and <u>
for underlined text.
Other formatting options are shown in this article on the Android Developers' site:

I had the same problem. Check wether plt.isinteractive()
is True. Setting it to 'False' helped for me.
plt.interactive(False)
This is because the original A activity is already being destroyed by the time you start it from B, C or D. Therefore, onCreate will be called in stead of onNewIntent(). One way of solving this is to always destroy the existing A(using FLAG_ACTIVITY_CLEAR_TASK | FLAG_ACTIVITY_NEW_TASK conjunction when startActivity) before starting a new A, so onCreate will always be called, and you put the code of onNewIntent() into onCreate by checking if getIntent() is the intent you started with.

stderr is usually unbuffered and stdout usually is. This can lead to odd looking output like this, which suggests code is executing in the wrong order. It isn't, it's just that the stdout buffer has yet to be flushed. Redirected or piped streams would of course not see this interleave as they would normally only see the output of stdout only or stderr only.
Although initially both stdout and stderr come to the console, both are separate and can be individually redirected.
Usage of final keyword in method calls.
For example why does the method test in below code does not give any compile error despite using final qualifier for the method parameter.
class Name {
private String name;
public Name (String s) {
this.name = s;
}
public void setName(String s) {
this.name = s;
}
}
private void test (final Name n) {
n.setName("test");
}
Quick solution I found was inside the pgAdmin program for windows. Under Tools menu there is a "Query Tool". Inside the Query Tool there is a Graphical Query Builder that can quickly show the database tables details. Good for a basic view
Sounds like you have a utility class similar to java.lang.Math.
The approach there is final class with private constructor and static methods.
But beware of what this does for testability, I recommend reading this article
Static Methods are Death to Testability

You can add a class (such as "success-dialog" in my example) to div#success, either directly in your HTML, or in your JavaScript by adding to the dialogClass option, as I've done.
$('#success').dialog({
height: 50,
width: 350,
modal: true,
resizable: true,
dialogClass: 'no-close success-dialog'
});
Then just add the success-dialog class to your CSS rules as appropriate. To indicate an element with two (or more) classes applied to it, just write them all together, with no spaces in between. For example:
.ui-dialog.success-dialog {
font-family: Verdana,Arial,sans-serif;
font-size: .8em;
}

is to obtain a parameter from the URI as well — see Spring Reference Chapter 16.3.3.3 Binding request parameters to method parameters with @RequestParamIf the URL http://localhost:8080/MyApp/user/1234/invoices?date=12-05-2013
gets the invoices for user 1234 on December 5th, 2013, the controller method would look like:
@RequestMapping(value="/user/{userId}/invoices", method = RequestMethod.GET)
public List<Invoice> listUsersInvoices(
@PathVariable("userId") int user,
@RequestParam(value = "date", required = false) Date dateOrNull) {
...
}
Also, request parameters can be optional, and as of Spring 4.3.3 path variables can be optional as well. Beware though, this might change the URL path hierarchy and introduce request mapping conflicts. For example, would /user/invoices
provide the invoices for user null
or details about a user with ID "invoices"?
Visual Studio 2015 RC, has LocalDb 12 installed, similar instructions to before but still shouldn't be required to know 'magic', before hand to use this, the default instance should have been turned on ... Rant complete, no for solution:
cmd> sqllocaldb start
Which will display
LocalDB instance "MSSQLLocalDB" started.
Your instance name might differ. Either way pop over to VS and open Server Explorer, right click Data Connections, choose Add, choose SQL Server, in the server name type:
(localdb)\MSSQLLocalDB
Without entering in a DB name, click 'Test Connection'.
I like the bytes.Buffer struct. I see it has ReadFrom and String methods. I've used it with a []byte but not an io.Reader.
I now found solution by using mysqli
instead of mysql
.
<?php
// enable error reporting
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
//connect to database
$connection = mysqli_connect("hostname", "user", "password", "db", "port");
//run the store proc
$result = mysqli_query($connection, "CALL StoreProcName");
//loop the result set
while ($row = mysqli_fetch_array($result)){
echo $row[0] . " - " . + $row[1];
}
I found that many people seem to have a problem with using mysql_connect, mysql_query and mysql_fetch_array
.
The issue is because your data source is not setup properly, to do that please verify your data source connection, in order to do that first navigate to Report Service Configuration Manager through
clicking on the start -> Start All -> Microsoft SQL Server ->Configuration Tool -> “Report Service Configuration Manager”
The open Report Manager URL and then navigate to the Data Source folder, see in the picture below
Then Create a Data Source or configure the one that is already there by right click on your database source and select "Manage" as is shown below
Now on the properties tab, on your left menu, fill out the data source with your connection string and username and password, after that click on test connection, and if the connection was successful, then click "Apply"
Navigate to the folder that contains your report in this case "SurveyLevelReport"
And Finally set your Report to the Data Source that you set up previously, and click Apply
This should work:
import os,sys
filename=os.path.basename(os.path.realpath(sys.argv[0]))
dirname=os.path.dirname(os.path.realpath(sys.argv[0]))
Or use awk
instead:
awk '/null/ { counter++; printf("%s%s%i\n",$0, " - Line number: ", NR)} END {print "Total null count: " counter}' file
Inside the filter inject this JavaScript which will bring the login page like this. If you don't do this then in your AJAX call you will get login page and the contents of login page will be appended.
Inside your filter or redirect insert this script in response:
String scr = "<script>window.location=\""+request.getContextPath()+"/login.do\"</script>";
response.getWriter().write(scr);
You may do it by using following code:
var url = "www.site.com/index.php#hello";
var hash = url.substring(url.indexOf('#')+1);
alert(hash);
