Suppose logical address space is **32 bit so total possible logical entries will be 2^32 and other hand suppose each page size is 4 byte then size of one page is *2^2*2^10=2^12...* now we know that no. of pages in page table is pages=total possible logical address entries/page size so pages=2^32/2^12 =2^20 Now suppose that each entry in page table takes 4 bytes then total size of page table in *physical memory will be=2^2*2^20=2^22=4mb***
In my case problem went away simply by using HttpContext.Current.Session
instead of Session

I was also facing a similar issue ("no runnable methods..") on running the simplest of simple piece of code (Using @Test, @Before etc.) and found the solution nowhere. I was using Junit4 and Eclipse SDK version 4.1.2. Resolved my problem by using the latest Eclipse SDK 4.2.2. I hope this helps people who are struggling with a somewhat similar issue.
Sbt version:
Append exclude("org.slf4j", "slf4j-log4j12")
to the dependency that transitively includes slf4j-log4j12
. For example, when using Spark with Log4j 2.6:
libraryDependencies ++= Seq(
// One SLF4J implementation (log4j-slf4j-impl) is here:
"org.apache.logging.log4j" % "log4j-api" % "2.6.1",
"org.apache.logging.log4j" % "log4j-core" % "2.6.1",
"org.apache.logging.log4j" % "log4j-slf4j-impl" % "2.6.1",
// The other implementation (slf4j-log4j12) would be transitively
// included by Spark. Prevent that with exclude().
"org.apache.spark" %% "spark-core" % "1.5.1" exclude("org.slf4j", "slf4j-log4j12")
)
According to: Java Revisited
Resources included by include directive are loaded during jsp translation time, while resources included by include action are loaded during request time.
Any change on included resources will not be visible in case of include directive until jsp file compiles again. While in case of include action, any change in included resource will be visible in the next request.
Include directive is static import, while include action is dynamic import.
Include directive uses file attribute to specify resources to be included while include action uses page attribute for the same purpose.
If I remember correctly the XmlDocument.Load(string) method always assumes UTF-8, regardless of the XML encoding. You would have to create a StreamReader with the correct encoding and use that as the parameter.
xmlDoc.Load(new StreamReader(
File.Open("file.xml"),
Encoding.GetEncoding("iso-8859-15")));
I just stumbled across KB308061 from Microsoft. There's an interesting passage: Specify the encoding declaration in the XML declaration section of the XML document. For example, the following declaration indicates that the document is in UTF-16 Unicode encoding format:
<?xml version="1.0" encoding="UTF-16"?>
Note that this declaration only specifies the encoding format of an XML document and does not modify or control the actual encoding format of the data.

There is preprocessor for Java which provides directives like #define, #ifdef, #ifndef and many others, for instance PostgresJDBC team uses it to generate sources for different cases and to not duplicate code.
There is no standard support for renaming properties in JavaScriptSerializer
however you can quite easily add your own:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.Script.Serialization;
using System.Reflection;
public class JsonConverter : JavaScriptConverter
{
public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer)
{
List<MemberInfo> members = new List<MemberInfo>();
members.AddRange(type.GetFields());
members.AddRange(type.GetProperties().Where(p => p.CanRead && p.CanWrite && p.GetIndexParameters().Length == 0));
object obj = Activator.CreateInstance(type);
foreach (MemberInfo member in members)
{
JsonPropertyAttribute jsonProperty = (JsonPropertyAttribute)Attribute.GetCustomAttribute(member, typeof(JsonPropertyAttribute));
if (jsonProperty != null && dictionary.ContainsKey(jsonProperty.Name))
{
SetMemberValue(serializer, member, obj, dictionary[jsonProperty.Name]);
}
else if (dictionary.ContainsKey(member.Name))
{
SetMemberValue(serializer, member, obj, dictionary[member.Name]);
}
else
{
KeyValuePair<string, object> kvp = dictionary.FirstOrDefault(x => string.Equals(x.Key, member.Name, StringComparison.InvariantCultureIgnoreCase));
if (!kvp.Equals(default(KeyValuePair<string, object>)))

{
PropertyInfo property = (PropertyInfo)member;
property.SetValue(obj, serializer.ConvertToType(value, property.PropertyType), null);
}

List<MemberInfo> members = new List<MemberInfo>();
members.AddRange(type.GetFields());
members.AddRange(type.GetProperties().Where(p => p.CanRead && p.CanWrite && p.GetIndexParameters().Length == 0));
Dictionary<string, object> values = new Dictionary<string, object>();
foreach (MemberInfo member in members)
{
JsonPropertyAttribute jsonProperty = (JsonPropertyAttribute)Attribute.GetCustomAttribute(member, typeof(JsonPropertyAttribute));
if (jsonProperty != null)
{
values[jsonProperty.Name] = GetMemberValue(member, obj);
}
else
{

}
}
return values;
}
private object GetMemberValue(MemberInfo member, object obj)
{
if (member is PropertyInfo)
{
PropertyInfo property = (PropertyInfo)member;
return property.GetValue(obj, null);
}
else if (member is FieldInfo)
{
FieldInfo field = (FieldInfo)member;
return field.GetValue(obj);
}
return null;
}
public override IEnumerable<Type> SupportedTypes

}
}
}
using System;

public class JsonPropertyAttribute : Attribute
{
public JsonPropertyAttribute(string name)
{
Name = name;
}
public string Name
{

}
}
The DataObject
class then becomes:
public class DataObject
{
[JsonProperty("user_id")]
public int UserId { get; set; }
[JsonProperty("detail_level")]
public DetailLevel DetailLevel { get; set; }
}
I appreicate this might be a little late but thought other people wanting to use the JavaScriptSerializer
rather than the DataContractJsonSerializer
might appreciate it.
These numbers come from the IEEE-754 standard, which defines the standard representation of floating point numbers. Wikipedia article at the link explains how to arrive at these ranges knowing the number of bits used for the signs, mantissa, and the exponent.
This is a bit late, but I just stumbled on this problem, trying to resolve my own problem of this kind. I then realized that I had this line in the ajax post wrong:
data: "{'quantity' : " + total_qty + ",'itemId':" + itemId + "}",
It should be:
data: "{quantity : '" + total_qty + "',itemId: '" + itemId + "'}",
As well as the WebMethod to:
public static string AddTo_Cart(string quantity, string itemId)
And this resolved my problem.
Hope it may be of help to someone else as well.
As with many tasks in ggplot, the general strategy is to put what you'd like to add to the plot into a data frame in a way such that the variables match up with the variables and aesthetics in your plot. So for example, you'd create a new data frame like this:
dfTab <- as.data.frame(table(df))
colnames(dfTab)[1] <- "x"
dfTab$lab <- as.character(100 * dfTab$Freq / sum(dfTab$Freq))
So that the x
variable matches the corresponding variable in df
, and so on. Then you simply include it using geom_text
:
ggplot(df) + geom_bar(aes(x,fill=x)) +
geom_text(data=dfTab,aes(x=x,y=Freq,label=lab),vjust=0) +
opts(axis.text.x=theme_blank(),axis.ticks=theme_blank(),
axis.title.x=theme_blank(),legend.title=theme_blank(),
axis.title.y=theme_blank())
This example will plot just the percentages, but you can paste
together the counts as well via something like this:
dfTab$lab <- paste(dfTab$Freq,paste("(",dfTab$lab,"%)",sep=""),sep=" ")
Note that in the current version of ggplot2, opts
is deprecated, so we would use theme
and element_blank
now.
I have fixed it with removing below code from
C:\wamp\bin\apache\apache2.4.9\conf\extra\httpd-vhosts.conf file
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "c:/Apache24/docs/dummy-host.example.com"
ServerName dummy-host.example.com
ServerAlias www.dummy-host.example.com
ErrorLog "logs/dummy-host.example.com-error.log"
CustomLog "logs/dummy-host.example.com-access.log" common
</VirtualHost>
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "c:/Apache24/docs/dummy-host2.example.com"
ServerName dummy-host2.example.com
ErrorLog "logs/dummy-host2.example.com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common
</VirtualHost>
And added
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot "c:/wamp/www"
ServerName localhost
ErrorLog "logs/localhost-error.log"
CustomLog "logs/localhost-access.log" common
</VirtualHost>
And it has worked like charm
I've faced same problem with my registry then i tried the solution listed below from a blog page. It works.
You can list your catalogs by calling this url:
http://YourPrivateRegistyIP:5000/v2/_catalog
Response will be in the following format:
{
"repositories": [
<name>,
...
]
}
You can list tags of your catalog by calling this url:
http://YourPrivateRegistyIP:5000/v2/<name>/tags/list
Response will be in the following format:
{
"name": <name>,
"tags": [
<tag>,
...
]
}
You can run this command in docker registry container:
curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X GET http://localhost:5000/v2/<name>/manifests/<tag> 2>&1 | grep Docker-Content-Digest | awk '{print ($3)}'
Response will be in the following format:
sha256:6de813fb93debd551ea6781e90b02f1f93efab9d882a6cd06bbd96a07188b073
Run the command given below with manifest value:
curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X DELETE http://127.0.0.1:5000/v2/<name>/manifests/sha256:6de813fb93debd551ea6781e90b02f1f93efab9d882a6cd06bbd96a07188b073
Run this command in your docker registy container:
bin/registry garbage-collect /etc/docker/registry/config.yml
Here is my config.yml
root@c695814325f4:/etc# cat /etc/docker/registry/config.yml
version: 0.1
log:
fields:
service: registry
storage:
cache:
blobdescriptor: inmemory

http:
addr: :5000
headers:
X-Content-Type-Options: [nosniff]
health:
storagedriver:

interval: 10s
threshold: 3
You can't have private
class but you can have second
class:
public class App14692708 {
public static void main(String[] args) {
PC pc = new PC();
System.out.println(pc);
}
}
class PC {
@Override
public String toString() {
return "I am PC instance " + super.toString();
}
}
Also remember that static
inner class is indistinguishable of separate class except it's name is OuterClass.InnerClass
. So if you don't want to use "closures", use static inner class.
var full_url = document.URL; // Get current url
var url_array = full_url.split('/') // Split the string into an array with / as separator
var last_segment = url_array[url_array.length-1]; // Get the last part of the array (-1)
alert( last_segment ); // Alert last segment
In C++, the size of int
isn't specified explicitly. It just tells you that it must be at least the size of short int
, which must be at least as large as signed char
. The size of char
in bits isn't specified explicitly either, although sizeof(char) is defined to be 1. If you want a 64 bit int, C++11 specifies long long
to be at least 64 bits.

Assuming that your entity name is "Photo", and that you create a CoreDataStack class...
func clearData() {
do {
let context = CoreDataStack.sharedInstance.persistentContainer.viewContext
let fetchRequest = NSFetchRequest<NSFetchRequestResult>(entityName: "Photo")
do {
let objects = try context.fetch(fetchRequest) as? [NSManagedObject]
_ = objects.map{$0.map{context.delete($0)}}
CoreDataStack.sharedInstance.saveContext()
} catch let error {
print("ERROR DELETING : \(error)")
}
}
}
Here is a good tutorial of how to use CoreData and how to use this method. https://medium.com/compileswift/parsing-json-response-and-save-it-in-coredata-step-by-step-fb58fc6ce16f#.1tu6kt8qb
Forgive me for being a Stack virgin... I'm not sure how to reply to Brian Ramsay's answer...
Using round will not work for second values between 59.5 and 59.99999. The second value will be 60 during this period. Use trunc instead...
double progress;
int minutes = floor(progress/60);
int seconds = trunc(progress - minutes * 60);
I think it's possible in Java 9:
animalMap.entrySet().stream()
.forEach(
pair -> Optional.ofNullable(pair.getValue())
.ifPresentOrElse(v -> myMap.put(pair.getKey(), v), v -> myList.add(pair.getKey())))
);
Need the ifPresentOrElse for it to work though. (I think a for loop looks better.)
var str1 = 'abc';
var str2 = str1+' def'; // str2 is now 'abc def'
Here is an alternative tr based solution that doesn't use echo, expressed as a one-liner.
for v in $(tr ',' '\n' <<< "$var") ; do something_with "$v" ; done
It feels tidier without echo but that is just my personal preference.
To make the post more comprehensive, for .NET Core devs there is FileExtensionContentTypeProvider class, which covers the official MIME content types.
It works behind the scene - sets ContentType in the Http Response headers based on the filename extension.
In case you need special MIME types, see example on customising the MIME types:
public void Configure(IApplicationBuilder app)
{
// Set up custom content types -associating file extension to MIME type
var provider = new FileExtensionContentTypeProvider();
// Add new mappings
provider.Mappings[".myapp"] = "application/x-msdownload";
provider.Mappings[".htm3"] = "text/html";
provider.Mappings[".image"] = "image/png";
// Replace an existing mapping
provider.Mappings[".rtf"] = "application/x-msdownload";
// Remove MP4 videos.
provider.Mappings.Remove(".mp4");
app.UseStaticFiles(new StaticFileOptions()
{
FileProvider = new PhysicalFileProvider(
Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot", "images")),
RequestPath = new PathString("/MyImages"),
ContentTypeProvider = provider
});
app.UseDirectoryBrowser(new DirectoryBrowserOptions()
{
FileProvider = new PhysicalFileProvider(
Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot", "images")),
RequestPath = new PathString("/MyImages")
});
}
None of the above worked for me, the only one working was
insert into tableName
select 11, 'BALOO' from sysibm.sysdummy1 union all
select 22, nullif('','') AS nullColumn from sysibm.sysdummy1
The nullif is used since it is not possible to pass null in the select statement otherwise.
Type in pip3 install yaml or like Connor pip3 install strictyaml
These steps work for me:
this question seem quite old but incase you come pass it, you can use the PHP inbuilt function array_push() to push data in an array using the example below.
<?php
$item = array();
foreach($group_membership as $i => $username) {
array_push($item, $username);
}
print_r($items);
?>

To print a specific row we have couple of pandas method
loc
- It only get label i.e column name or Featuresiloc
- Here i stands for integer, actually row number ix
- It is a mix of label as well as integerHow to use for specific row
loc
df.loc[row,column]
For first row and all column
df.loc[0,:]
For first row and some specific column
df.loc[0,'column_name']
iloc
For first row and all column
df.iloc[0,:]
For first row and some specific column i.e first three cols
df.iloc[0,0:3]
Python solution
def subtree(node, relationships):
return {
v: subtree(v, relationships)
for v in [x[0] for x in relationships if x[1] == node]
}
For example:
# (child, parent) pairs where -1 means no parent
flat_tree = [
(1, -1),
(4, 1),
(10, 4),
(11, 4),
(16, 11),
(17, 11),

(2, 23),
(26, 23),
(27, 23),
(20, 9),
(21, 9)
]
subtree(-1, flat_tree)
Produces:

I had this problem too. But this was because of another reason.
My password began with character $
... e.g. $MyPassword
I've changed it to #MyPassword
and the problem is solved.
Many questions and interviews are available at http://www.techinterviews.com/interview-questions/java and I don't really see value in copy / pasting a selection of them.
No, it's up to you to create your own compilation of things you think are important. Personally, I proceed always in two steps: first a few questions to get a basic idea of the experience and skills, then a problem solving situation. I'm indeed not convinced that being able to answer any known questions makes you a good or bad unknown problems solver. So, I prefer to ask people to solve a given problem, to give them some requirements, and ask them to write code (but not on paper). I give them some time to come back to me and check how they did it, their coding style, how they used the suggested APIs, etc.
That all being said, my favorite question is "what don't you like about Java?" (in the spirit of this one). It is really a excellent question, it gives you an immediate feedback on how much a candidate has used Java and explored its API and if he just religious about it or not (as the OP wrote).
Update: As suggested by CPerkins, a better wording for the question suggested above might be "What would you most like to see changed in Java?". And indeed, I prefer this way.
For symfony 2.6 and above we can use

In Bash 4:
name="Ricardo"
read -e -i "$name" -p "Please enter your name: " input
name="${input:-$name}"
This displays the name after the prompt like this:
Please enter your name: Ricardo
with the cursor at the end of the name and allows the user to edit it. The last line is optional and forces the name to be the original default if the user erases the input or default (submitting a null).
I will just repeat what @Ivo Bosticky said which can be overlooked. Put these lines at the VERY start of the py file.
import matplotlib
matplotlib.use('Agg')
Or one would get error
*/usr/lib/pymodules/python2.7/matplotlib/__init__.py:923: UserWarning: This call to matplotlib.use() has no effect because the the backend has already been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot,*
This will resolve all Display issue
That directory is part of your user data and you can delete any user data without affecting Xcode seriously. You can delete the whole CoreSimulator/ directory. Xcode will recreate fresh instances there for you when you do your next simulator run. If you can afford losing any previous simulator data of your apps this is the easy way to get space.
Update: A related useful app is "DevCleaner for Xcode" https://apps.apple.com/app/devcleaner-for-xcode/id1388020431
Simple solution, I've tested is
webBrowser1.Refresh();
var str = "<html><head></head><body>" + sender.ToString() + "</body></html>";
webBrowser1.DocumentText = str;
I think the word you're looking for is "overloading". There isn't any method overloading in Python. You can however use default arguments, as follows.
def stackoverflow(self, i=None):
if i != None:
print 'second method', i
else:
print 'first method'
When you pass it an argument, it will follow the logic of the first condition and execute the first print statement. When you pass it no arguments, it will go into the else
condition and execute the second print statement.
It's also possible to get this error if you are running the test project using JUnit instead of Android JUnit. Naturally, the solution is just to change how you run it.
It work for Mac also
import os
path="/Users/HOME/Desktop/Addl Work/TimeSeries-Done"
os.chdir(path)
To check working directory
os.getcwd()
It partly depends on which overload you're talking about, but the basic idea is:
(currentValue, sequenceValue)
into (nextValue)
currentValue = nextValue
currentValue
You may find the Aggregate
post in my Edulinq series useful - it includes a more detailed description (including the various overloads) and implementations.
One simple example is using Aggregate
as an alternative to Count
:
// 0 is the seed, and for each item, we effectively increment the current value.
// In this case we can ignore "item" itself.
int count = sequence.Aggregate(0, (current, item) => current + 1);
Or perhaps summing all the lengths of strings in a sequence of strings:
int total = sequence.Aggregate(0, (current, item) => current + item.Length);
Personally I rarely find Aggregate
useful - the "tailored" aggregation methods are usually good enough for me.
U can also use CoreImage to create blurred image with dark effect
Make snapshot for image
func snapShotImage() -> UIImage {
UIGraphicsBeginImageContext(self.frame.size)
if let context = UIGraphicsGetCurrentContext() {
self.layer.renderInContext(context)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
return UIImage()
}
Apply CoreImage Filters as u wish with
private func bluredImage(view:UIView, radius:CGFloat = 1) -> UIImage {
let image = view.snapShotImage()
if let source = image.CGImage {
let context = CIContext(options: nil)
let inputImage = CIImage(CGImage: source)
let clampFilter = CIFilter(name: "CIAffineClamp")
clampFilter?.setDefaults()
clampFilter?.setValue(inputImage, forKey: kCIInputImageKey)
if let clampedImage = clampFilter?.valueForKey(kCIOutputImageKey) as? CIImage {
let explosureFilter = CIFilter(name: "CIExposureAdjust")
explosureFilter?.setValue(clampedImage, forKey: kCIInputImageKey)
explosureFilter?.setValue(-1.0, forKey: kCIInputEVKey)
if let explosureImage = explosureFilter?.valueForKey(kCIOutputImageKey) as? CIImage {
let filter = CIFilter(name: "CIGaussianBlur")
filter?.setValue(explosureImage, forKey: kCIInputImageKey)
filter?.setValue("\(radius)", forKey:kCIInputRadiusKey)
if let result = filter?.valueForKey(kCIOutputImageKey) as? CIImage {
let bounds = UIScreen.mainScreen().bounds
let cgImage = context.createCGImage(result, fromRect: bounds)
let returnImage = UIImage(CGImage: cgImage)
return returnImage
}
}
}
}
return UIImage()
}
Module
using ng generate module <module name>
.ng generate component <component name> --module=<module name>
Solution:
wget -r -np -nH --cut-dirs=3 -R index.html http://hostname/aaa/bbb/ccc/ddd/
Explanation:
-r
: recursively -np
: not going to upper directories, like ccc/…-nH
: not saving files to hostname folder --cut-dirs=3
: but saving it to ddd by omitting
first 3 folders aaa, bbb, ccc-R index.html
: excluding index.html
files I would also try it this way
1) Create the Java Beans from the JSON schema
2) Use JSON parser libraries to avoid any sort of exception
3) Cast the parse result to the Java object that was created from the initial JSON schema.

This is code for checking whether a particular service is running. I'm fairly sure it can work for an activity too as long as you change getRunningServices with getRunningAppProcesses() or getRunningTasks(). Have a look here http://developer.android.com/reference/android/app/ActivityManager.html#getRunningAppProcesses()
Change Constants.PACKAGE and Constants.BACKGROUND_SERVICE_CLASS accordingly
public static boolean isServiceRunning(Context context) {
Log.i(TAG, "Checking if service is running");
ActivityManager activityManager = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);
boolean isServiceFound = false;
for (int i = 0; i < services.size(); i++) {
if (Constants.PACKAGE.equals(services.get(i).service.getPackageName())){
if (Constants.BACKGROUND_SERVICE_CLASS.equals(services.get(i).service.getClassName())){
isServiceFound = true;
}
}
}
Log.i(TAG, "Service was" + (isServiceFound ? "" : " not") + " running");
return isServiceFound;
}
tr
can be more concise for removing characters than sed
or awk
, especially when you want to remove different characters from a string.
Removing double quotes:
echo '"Hi"' | tr -d \"
# Produces Hi without quotes
Removing different kinds of brackets:
echo '[{Hi}]' | tr -d {}[]
# Produces Hi without brackets
-d
stands for "delete".
This seems to work for me.

A rather roundabout way, just for completeness:

Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.
Looks like above solutions aren't using compare method and implementing total again so here is my solution and hope it works for you (It's working fine).
#include<iostream>
#include<cstring>
#include<cmath>
using namespace std;
string tolow(string a)
{
for(unsigned int i=0;i<a.length();i++)
{
a[i]=tolower(a[i]);
}
return a;
}
int main()
{
string str1,str2;
cin>>str1>>str2;
int temp=tolow(str1).compare(tolow(str2));
if(temp>0)
cout<<1;
else if(temp==0)
cout<<0;
else
cout<<-1;
}
If you do use moment.js you would use the moment().utc() function to convert a moment object to UTC. You can also handle a nice format inside the controller instead of the view by using the moment().format() function. For example:
moment(myDate).utc().format('MM/DD/YYYY')
I'd like to share my experience of using Ant in building projects, *.properties files should be copied explicitly. This is because Ant will not compile *.properties files into the build working directory by default (javac just ignore *.properties). For example:
<target name="compile" depends="init">
<javac destdir="${dst}" srcdir="${src}" debug="on" encoding="utf-8" includeantruntime="false">
<include name="com/example/**" />
<classpath refid="libs" />
</javac>
<copy todir="${dst}">
<fileset dir="${src}" includes="**/*.properties" />
</copy>
</target>
<target name="jars" depends="compile">
<jar jarfile="${app_jar}" basedir="${dst}" includes="com/example/**/*.*" />
</target>
Please notice that 'copy' section under the 'compile' target, it will replicate *.properties files into the build working directory. Without the 'copy' section the jar file will not contain the properties files, then you may encounter the java.util.MissingResourceException.
Delete generated R package from your referenced library. Sometimes Clean and Rebuild doesn't remove old R generated files.
Here very simple method
let data = string.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
I've also had this error when trying to pull the changes into a branch which is not created from the upstream branch from which I'm trying to pull.
Eg - This creates a new branch matching night-version
of upstream
git checkout upstream/night-version -b testnightversion
This creates a branch testmaster
in local which matches the master
branch of upstream.
git checkout upstream/master -b testmaster
Now if I try to pull the changes of night-version
into testmaster
branch leads to this error.
git pull upstream night-version //while I'm in `master` cloned branch
I managed to solve this by navigating to proper branch and pull the changes.
git checkout testnightversion
git pull upstream night-version // works fine.
string json = w.JSON;
var serializer = new JavaScriptSerializer();
serializer.RegisterConverters(new[] { new DynamicJsonConverter() });
DynamicJsonConverter.DynamicJsonObject obj =
(DynamicJsonConverter.DynamicJsonObject)serializer.Deserialize(json, typeof(object));
Now obj._Dictionary
contains a dictionary. Perfect!
This code must be used in conjunction with Deserialize JSON into C# dynamic object? + make the _dictionary variable from "private readonly" to public in the code there
For those who are able to access cpanel, there is a simpler way getting around it.
log in cpanel => "Remote MySQL" under DATABASES section:
Add the IPs / hostname which you are accessing from
done!!!
Wouldn't this work?
var isFile = Regex.IsMatch(path, @"\w{1,}\.\w{1,}$");
Go to this link
Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download
Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.
Here's a copy of PJ Hyett's post, as it is not available anymore:
Git Isn't Hard
Nov 23, 2008
When we tell people why they should use Git over Subversion, the go-to line is, “Git does Subversion better than Subversion, but it does a lot more than that.”
The “lot more” is comprised of a bunch of stuff that makes Git really shine, but it can be pretty overwhelming for those coming from other SCM’s like Subversion.
That said, there’s nothing stopping you from using Git just like you use Subversion while you’re making the transition.
Assuming you’ve installed the necessary software and have a remote repository somewhere, this is how you would grab the code and push your changes back with Subversion:
$ svn checkout svn://foo.googlecode.com/svn/trunk foo
# make your changes
$ svn commit -m "my first commit"
And how would you do it in Git:
$ git clone [email protected]:pjhyett/foo.git
# make your changes
$ git commit -a -m "my first commit"
$ git push
One more command to make it happen in Git. That extra command has large implications, but for the purposes of this post, that’s all we’re talking about, one extra command.
See, it really isn’t that hard.
Update: I’d be remiss to not also mention that the equivalent of updating your local copy in Subversion compared to Git is
svn update
andgit pull
, respectively. Only one command in both cases.
I think Java is fine as it is, adding unsigned would complicate it without much gain. Even with the simplified integer model, most Java programmers don't know how the basic numeric types behave - just read the book Java Puzzlers to see what misconceptions you might hold.
As for practical advice:
If your values are somewhat arbitrary size and don't fit into int
, use long
.
If they don't fit into long
use BigInteger
.
Use the smaller types only for arrays when you need to save space.
If you need exactly 64/32/16/8 bits, use long
/int
/short
/byte
and stop worrying about the sign bit, except for division, comparison, right shift, and casting.

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below
e.g.
Exec N'Select bla..'
the N defines string literal is unicode.
Use Hosts Commander. It's simple and powerful. Translated description (from russian) here.
hosts add another.dev 192.168.1.1 # Remote host
hosts add test.local # 127.0.0.1 used by default
hosts set myhost.dev # new comment
hosts rem *.local
hosts enable local*
hosts disable localhost
...and many others...
Usage:
hosts - run hosts command interpreter
hosts <command> <params> - execute hosts command
Commands:
add <host> <aliases> <addr> # <comment> - add new host
set <host|mask> <addr> # <comment> - set ip and comment for host
rem <host|mask> - remove host
on <host|mask> - enable host
off <host|mask> - disable host
view [all] <mask> - display enabled and visible, or all hosts
hide <host|mask> - hide host from 'hosts view'
show <host|mask> - show host in 'hosts view'
print - display raw hosts file
format - format host rows
clean - format and remove all comments
rollback - rollback last operation
backup - backup hosts file
restore - restore hosts file from backup
recreate - empty hosts file
open - open hosts file in notepad
They're completely different. Objective C has more in common with Smalltalk than with C++ (well, except for the syntax, really).
You have to specify the format (fmt
) of you data in savetxt
, in this case as a string (%s
):
num.savetxt('test.txt', DAT, delimiter=" ", fmt="%s")
The default format is a float, that is the reason it was expecting a float instead of a string and explains the error message.
Standard javascript will do that using the following syntax:
string.substring(from, to)
var name = "nameGorge";
var output = name.substring(4);

As a one-liner into vim:
:set tabstop=4 shiftwidth=4
For permanent setup, add these lines to ~/.vimrc:
set tabstop=4
set shiftwidth=4
NOTE: Add set expandtab
if you prefer 4-spaces indentation, instead of a tab indentation.

Make sure you image is a relative path such as:
@Url.Content("~/Content/images/myimage.png")
MVC4
<img src="~/Content/images/myimage.png" />
You could convert the byte[]
into a Base64
string
on the fly.
string base64String = Convert.ToBase64String(imageBytes);
<img src="@String.Format("data:image/png;base64,{0}", base64string)" />
Exponentiation by squaring.
int ipow(int base, int exp)
{
int result = 1;
for (;;)
{
if (exp & 1)
result *= base;
exp >>= 1;
if (!exp)
break;
base *= base;
}
return result;
}
This is the standard method for doing modular exponentiation for huge numbers in asymmetric cryptography.
you can add the Path to coinhsl lib to LD_LIBRARY_PATH
variable. May be that will help.
export LD_LIBRARY_PATH=/xx/yy/zz:$LD_LIBRARY_PATH
where /xx/yy/zz
represent the path to coinhsl
lib.
Some answers are slightly incorrect and point to the wrong part of the docs:
If you want a component to render nothing, just return null
, as per doc:
In rare cases you might want a component to hide itself even though it was rendered by another component. To do this return null instead of its render output.
If you try to return undefined
for example, you'll get the following error:
Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null.
As pointed out by other answers, null
, true
, false
and undefined
are valid children which is useful for conditional rendering inside your jsx, but it you want your component to hide / render nothing, just return null
.
This is not an error message but a warning. It is very clearly explained in their website as :
This warning, i.e. not an error, message is reported when no SLF4J providers could be found on the class path. Placing one (and only one) of slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem. Note that these providers must target slf4j-api 1.8 or later.
In the absence of a provider, SLF4J will default to a no-operation (NOP) logger provider.
Within code you will now have access to read the variable as
string myString = Variables.MyVariableName.ToString();
In Python 2.7 with iPython:
>>> import os
>>> os.getenv??
Signature: os.getenv(key, default=None)
Source:
def getenv(key, default=None):
"""Get an environment variable, return None if it doesn't exist.
The optional second argument can specify an alternate default."""
return environ.get(key, default)
File: ~/venv/lib/python2.7/os.py
Type: function
So we can conclude os.getenv
is just a simple wrapper around os.environ.get
.
There is a pretty good example on https://developers.google.com/maps/documentation/javascript/examples/geocoding-simple
To shorten it up a little:
geocoder = new google.maps.Geocoder();
function codeAddress() {
//In this case it gets the address from an element on the page, but obviously you could just pass it to the method instead
var address = document.getElementById( 'address' ).value;
geocoder.geocode( { 'address' : address }, function( results, status ) {
if( status == google.maps.GeocoderStatus.OK ) {
//In this case it creates a marker, but you can get the lat and lng from the location.LatLng
map.setCenter( results[0].geometry.location );
var marker = new google.maps.Marker( {
map : map,
position: results[0].geometry.location
} );
} else {
alert( 'Geocode was not successful for the following reason: ' + status );
}
} );
}
NOTE: Though this is possible, it is not at all recommended as it kind of destroys the reason for inheritance. The best way would be to restructure your application design so that there are NO parent to child dependencies. A parent should not ever need to know its children or their capabilities.
However.. you should be able to do it like:
void calculate(Person p) {
((Student)p).method();
}
a safe way would be:
void calculate(Person p) {
if(p instanceof Student) ((Student)p).method();
}
Here's how I handle that:
$this->response_body = @file_get_contents($this->url, false, $context);
if ($this->response_body === false) {
$error = error_get_last();
$error = explode(': ', $error['message']);
$error = trim($error[2]) . PHP_EOL;
fprintf(STDERR, 'Error: '. $error);
die();
}
As other answers pointed out, it is most likely generated by some tool.
But if I were the original author of the file, my answer would be: Consistency.
If I am not allowed to put double quotes in my attributes, why put them in the element's content ? Why do these specs always have these exceptional cases ..
If I had to write the HTML spec, I would say All double quotes need to be encoded
. Done.
Today it is like In attribute values we need to encode double quotes, except when the attribute value itself is defined by single quotes. In the content of elements, double quotes can be, but are not required to be, encoded.
(And I am surely forgetting some cases here).
Double quotes are a keyword of the spec, encode them. Lesser/greater than are a keyword of the spec, encode them. etc..
Using Array.Filter() with Arrow Functions we can achieve this using
users = users.filter(x => x.name == 'Mark' && x.address == 'England');
Here is the complete snippet
// initializing list of users_x000D_
var users = [{_x000D_
name: 'John',_x000D_
email: '[email protected]',_x000D_

_x000D_
//filtering the users array and saving _x000D_

console.log(users);

I just saw the RSpec's code has some comment on require_relative
being O(1) constant and require
being O(N) linear. So probably the difference is that require_relative
is the preferred one than require
.

vote
method which creates a fresh HTTP connection.HttpClient
instance to post to the server. This way it wont create too many connections from the client side. HttpClient
needs to be shut and hence call httpclient.getConnectionManager().shutdown();
to release the resources used by the connections. The standard solution:
expr $d1 - $d2
You can also do:
echo $(( d1 - d2 ))
but beware that this will treat 07

is the same as 7

1- There is no way to actually destroy an object in javascript, but using delete
, we could remove a reference from an object:
var obj = {};
obj.mypointer = null;
delete obj.mypointer;
2- The important point about the delete
keyword is that it does not actually destroy the object BUT if only after deleting that reference to the object, there is no other reference left in the memory pointed to the same object, that object would be marked as collectible. The delete
keyword deletes the reference but doesn't GC the actual object. it means if you have several references of the same object, the object will be collected just after you delete all the pointed references.
3- there are also some tricks and workarounds that could help us out, when we want to make sure we do not leave any memory leaks behind. for instance if you have an array consisting several objects, without any other pointed reference to those objects, if you recreate the array all those objects would be killed. For instance if you have var array = [{}, {}]
overriding the value of the array like array = []
would remove the references to the two objects inside the array and those two objects would be marked as collectible.
4- for your solution the easiest way is just this:
var storage = {};
storage.instance = new Class();
//since 'storage.instance' is your only reference to the object, whenever you wanted to destroy do this:
storage.instance = null;
// OR
delete storage.instance;
As mentioned above, either setting storage.instance = null
or delete storage.instance
would suffice to remove the reference to the object and allow it to be cleaned up by the GC. The difference is that if you set it to null
then the storage object still has a property called instance (with the value null). If you delete storage.instance
then the storage object no longer has a property named instance.
and WHAT ABOUT destroy method ??
the paradoxical point here is if you use instance.destroy
in the destroy function you have no access to the actual instance
pointer, and it won't let you delete it.
The only way is to pass the reference to the destroy function and then delete it:
// Class constructor
var Class = function () {
this.destroy = function (baseObject, refName) {
delete baseObject[refName];
};
};
// instanciate
var storage = {};
storage.instance = new Class();
storage.instance.destroy(object, "instance");
console.log(storage.instance); // now it is undefined
BUT if I were you I would simply stick to the first solution and delete the object like this:
storage.instance = null;
// OR
delete storage.instance;
WOW it was too much :)

To help guard against SQL injection, I normally try to use functions wherever possible. In this case, you could do:
...
SET @TableName = '<[db].><[schema].>tblEmployees'
SET @TableID = OBJECT_ID(TableName) --won't resolve if malformed/injected.
...
SET @SQLQuery = 'SELECT * FROM ' + OBJECT_NAME(@TableID) + ' WHERE EmployeeID = @EmpID'
Actually, in this case it's quite simple: apply the vertical align to the image. Since it's all in one line, it's really the image you want aligned, not the text.

Just remember, having "100% code-coverage" doesn't mean everything is tested completely - while it means every line of code is tested, it doesn't mean they are tested under every (common) situation..
I would use code-coverage to highlight bits of code that I should probably write tests for. For example, if whatever code-coverage tool shows myImportantFunction() isn't executed while running my current unit-tests, they should probably be improved.
Basically, 100% code-coverage doesn't mean your code is perfect. Use it as a guide to write more comprehensive (unit-)tests.
Simple solution to achieve "split in two" background:
background: linear-gradient(to left, #ff0000 50%, #0000ff 50%);
You can also use degrees as direction
background: linear-gradient(80deg, #ff0000 50%, #0000ff 50%);
just override onCreateOptionsMenu like this in your MainPage.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
For getting the element in react
you need to use ref
and inside the function you can use the ReactDOM.findDOMNode
method.
But what I like to do more is to call the ref right inside the event
<input type="text" ref={ref => this.myTextInput = ref} />
This is some good link to help you figure out.
Here is the complete solution for PostgreSQL 9+, updated recently.
CREATE USER readonly WITH ENCRYPTED PASSWORD 'readonly';
GRANT USAGE ON SCHEMA public to readonly;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO readonly;
-- repeat code below for each database:
GRANT CONNECT ON DATABASE foo to readonly;
\c foo
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO readonly; --- this grants privileges on new tables generated in new database "foo"
GRANT USAGE ON SCHEMA public to readonly;
GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO readonly;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO readonly;
Thanks to https://jamie.curle.io/creating-a-read-only-user-in-postgres/ for several important aspects
If anyone find shorter code, and preferably one that is able to perform this for all existing databases, extra kudos.
Ted Hopp answered this quite nicely. I have been using res/raw for my opengl texture and shader files. I was thinking about moving them to an assets directory to provide a hierarchical organization.
This thread convinced me not to. First, because I like the use of a unique resource id. Second because it's very simple to use InputStream/openRawResource or BitmapFactory to read in the file. Third because it's very useful to be able to use in a portable library.

If you use the -o
option, Mac OS X’s ping
will exit after receiving one reply packet.
Further reading: http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man8/ping.8.html
EDIT: paxdiablo makes a very good point about using ping
’s exit status to your advantage. I would do something like:
#!/usr/bin/env bash
echo 'Begin ping'
if ping -oc 100000 8.8.8.8 > /dev/null; then
echo $(say 'timeout')
else
echo $(say 'the Internet is back up')
fi
ping
will send up to 100,000 packets and then exit with a failure status—unless it receives one reply packet, in which case it exits with a success status. The if
will then execute the appropriate statement.
If you are looking for features that notebooks in JupyterLab have that traditional Jupyter Notebooks do not, check out the JupyterLab notebooks documentation. There is a simple video showing how to use each of the features in the documentation link.
JupyterLab notebooks have the following features and more:
If you don't have the token at the time of the call is made, You will have to make two calls, one to get the token and the other to extract the token form the response, pay attention to
grep token | cut -d, -f1 | cut -d\" -f4
as it is the part which is dealing with extracting the token from the response.
echo "Getting token response and extracting token"
def token = sh (returnStdout: true, script: """
curl -S -i -k -X POST https://www.example.com/getToken -H \"Content-Type: application/json\" -H \"Accept: application/json\" -d @requestFile.json | grep token | cut -d, -f1 | cut -d\\" -f4
""").split()
After extracting the token you can use the token to make subsequent calls as follows.
echo "Token : ${token[-1]}"
echo "Making calls using token..."
curl -S -i -k -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer ${token[-1]}" https://www.example.com/api/resources

If your page does not modify any session variables, you can opt out of most of this lock.
<% @Page EnableSessionState="ReadOnly" %>
If your page does not read any session variables, you can opt out of this lock entirely, for that page.
<% @Page EnableSessionState="False" %>
If none of your pages use session variables, just turn off session state in the web.config.
<sessionState mode="Off" />
I'm curious, what do you think "a ThreadSafe collection" would do to become thread-safe, if it doesn't use locks?
Edit: I should probably explain by what I mean by "opt out of most of this lock". Any number of read-only-session or no-session pages can be processed for a given session at the same time without blocking each other. However, a read-write-session page can't start processing until all read-only requests have completed, and while it is running it must have exclusive access to that user's session in order to maintain consistency. Locking on individual values wouldn't work, because what if one page changes a set of related values as a group? How would you ensure that other pages running at the same time would get a consistent view of the user's session variables?
I would suggest that you try to minimize the modifying of session variables once they have been set, if possible. This would allow you to make the majority of your pages read-only-session pages, increasing the chance that multiple simultaneous requests from the same user would not block each other.

You should have a look at moment
which is a python port of the excellent js lib momentjs
.
One advantage of it is the support of ISO 8601
strings formats, as well as a generic "% format" :
import moment
time_string='2012-10-09T19:00:55Z'
m = moment.date(time_string, '%Y-%m-%dT%H:%M:%SZ')
print m.format('YYYY-M-D H:M')
print m.weekday
Result:
2012-10-09 19:10

This should be close to what you are looking for your first example:
=SUM(INDIRECT("A1:A"&B1,TRUE))
This should be close to what you are looking for your final example:
=SUM(INDIRECT("A"&1+B1&":A"&B1,TRUE))
To add yet another answer to the pile (because apparently there's so many ways of doing it depending on your setup) - I did it by selecting the literal option
element and clicking it
find(".some-selector-for-dropdown option[value='1234']").select_option
It's not very pretty, but it works :/
Clicking but then cancelling "Enable Automatic Signing" worked for me, although the actual change it made was:
ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = YES;
or in Xcode it's called Always Embed Swift Standard Libraries
The colors changed due to the order of CSS files.
Place the custom CSS under the bootstrap CSS.
Prerequisite:
sudo apt-get install build-essential gfortran libatlas-base-dev python-pip python-dev
sudo pip install --upgrade pip
Actual packages:
sudo pip install numpy
sudo pip install scipy
Optional packages:
sudo pip install matplotlib OR sudo apt-get install python-matplotlib
sudo pip install -U scikit-learn
sudo pip install pandas
Second Approach :
angular.module('myApp', [])
.controller('Ctrl1', ['$scope',
function($scope) {
$scope.prop1 = "First";
$scope.clickFunction = function() {
$scope.$broadcast('update_Ctrl2_controller', $scope.prop1);
};
}
])
.controller('Ctrl2', ['$scope',
function($scope) {
$scope.prop2 = "Second";
$scope.$on("update_Ctrl2_controller", function(event, prop) {
$scope.prop = prop;
$scope.both = prop + $scope.prop2;
});
}
])
Html :
<div ng-controller="Ctrl2">
<p>{{both}}</p>
</div>
<button ng-click="clickFunction()">Click</button>

I have tried some methods above. However, the experiment by @zbinsd has its limitation. The sparsity of matrix used in the experiment is extremely low while the real sparsity is usually over 90%. In my condition, the sparse is with the shape of (7000, 25000) and the sparsity of 97%. The method 4 is extremely slow and I can't tolerant getting the results. I use the method 6 which is finished in 10 s. Amazingly, I try the method below and it's finished in only 0.247 s.
import sklearn.preprocessing as pp
def cosine_similarities(mat):
col_normed_mat = pp.normalize(mat.tocsc(), axis=0)

I try different solutions but nothing help. But this steps (My GitBash SSH environment always asks for my passphrase, what can I do?) from Bitbucket.com seams works well :
The idea is:
you create ~/.bashrc
file
add follow script:
SSH_ENV=$HOME/.ssh/environment
# start the ssh-agent
function start_agent {
echo "Initializing new SSH agent..."
# spawn ssh-agent
/usr/bin/ssh-agent | sed 's/^echo/#echo/' > "${SSH_ENV}"
echo succeeded
chmod 600 "${SSH_ENV}"
. "${SSH_ENV}" > /dev/null
/usr/bin/ssh-add
}
if [ -f "${SSH_ENV}" ]; then
. "${SSH_ENV}" > /dev/null
ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
start_agent;
}
else
start_agent;
fi
re-run Bash
With the Underscore.js library:
var hash = {
foo: 1,
bar: 2
};
(_.invert(hash))[1]; // => 'foo'
You can try this:
var theValue = document.getElementById("demo").getAttribute("value");
None of these answers work if the variable is an uninitialized generic type
And from what I can find, it's only possible using an extremely ugly workaround, or by passing in an initialized parameter to your function, making it in-place, see here:
<T> T MyMethod(...){ if(T.class == MyClass.class){...}}
Is NOT valid because you cannot pull the type out of the T
parameter directly, since it is erased at runtime time.
<T> void MyMethod(T out, ...){ if(out.getClass() == MyClass.class){...}}
This works because the caller is responsible to instantiating the variable out
before calling. This will still throw an exception if out is null when called, but compared to the linked solution, this is by far the easiest way to do this
I know this is a kind of specific application, but since this is the first result on google for finding the type of a variable with java (and given that T
is a kind of variable), I feel it should be included
Or you can use temporary array and then delete the real one if you want to change it while in cycle:
$array = array(0 => 'a', 1 => 'b', 2 => 'c');
$temp_array = $array[1];
unset($array[1]);
array_unshift($array , $temp_array);
the output will be:
array(0 => 'b', 1 => 'a', 2 => 'c')
and when are doing it while in cycle, you should clean $temp_array
after appending item to array.
If you are doing this in a browser, you can capture keyboard events.
Can all be listened to on HTML nodes in most browsers.
Webkit also supports...

(Make sure to install react-router using npm!)
To use react-router, you do the following:
Create a file with routes defined using Route, IndexRoute components
Inject the Router (with 'r'!) component as the top-level component for your app, passing the routes defined in the routes file and a type of history (hashHistory, browserHistory)
Step 1 routes.js
import React from 'react';
import { Route, IndexRoute } from 'react-router';
/**
* Import all page components here
*/
import App from './components/App';
import MainPage from './components/MainPage';
import SomePage from './components/SomePage';
import SomeOtherPage from './components/SomeOtherPage';
/**
* All routes go here.
* Don't forget to import the components above after adding new route.
*/
export default (
<Route path="/" component={App}>
<IndexRoute component={MainPage} />
<Route path="/some/where" component={SomePage} />
<Route path="/some/otherpage" component={SomeOtherPage} />
</Route>
);
Step 2 entry point (where you do your DOM injection)
// You can choose your kind of history here (e.g. browserHistory)
import { Router, hashHistory as history } from 'react-router';
// Your routes.js file
import routes from './routes';
ReactDOM.render(
<Router routes={routes} history={history} />,
document.getElementById('your-app')
);
Step 3 The App component (props.children)
In the render for your App component, add {this.props.children}:
render() {
return (
<div>
<header>
This is my website!
</header>
<main>
{this.props.children}
</main>
<footer>
Your copyright message
</footer>
</div>
);
}
Step 4 Use Link for navigation
Anywhere in your component render function's return JSX value, use the Link component:
import { Link } from 'react-router';
(...)
<Link to="/some/where">Click me</Link>
In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:
<script type="javascript">
day = new Array(<?php echo implode(',', $day); ?>);
week = new Array(<?php echo implode(',',$week); ?>);
month = new Array(<?php echo implode(',',$month); ?>);
<!-- Then pass it to the JavaScript function: -->
drawChart(<?php echo count($day); ?>, day, week, month);
</script>
Apple's Technical Q&A QA1509 shows the following simple approach:
CFDataRef CopyImagePixels(CGImageRef inImage)
{
return CGDataProviderCopyData(CGImageGetDataProvider(inImage));
}
Use CFDataGetBytePtr
to get to the actual bytes (and various CGImageGet*
methods to understand how to interpret them).
I think the easiest way to do this is to use the Regular Expressions. This way you can get the same split count as you could using myVar.Split('x') but in a multiple character setting.
string myVar = "do this to count the number of words in my wording so that I can word it up!";
int count = Regex.Split(myVar, "word").Length;
To create a patch with both modified & new files (staged) you can run:
git diff HEAD > file_name.patch
For the 24-hour time, you need to use HH24
instead of HH
.
For the 12-hour time, the AM/PM indicator is written as A.M.
(if you want periods in the result) or AM
(if you don't). For example:
SELECT invoice_date,
TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
FROM invoices
;
For more information on the format models you can use with TO_CHAR
on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.
IFrame is just an "internal frame". The reason why it can be considered less secure (than not using any kind of frame at all) is because you can include content that does not originate from your domain.
All this means is that you should trust whatever you include in an iFrame or a regular frame.
Frames and IFrames are equally secure (and insecure if you include content from an untrusted source).
I didn't find any example explicit enough for me on how to use java.util.function.Function
for simple method as parameter function. Here is a simple example:
import java.util.function.Function;
public class Foo {
private Foo(String parameter) {
System.out.println("I'm a Foo " + parameter);
}
public static Foo method(final String parameter) {
return new Foo(parameter);
}
private static Function parametrisedMethod(Function<String, Foo> function) {
return function;
}
public static void main(String[] args) {
parametrisedMethod(Foo::method).apply("from a method");
}
}
Basically you have a Foo
object with a default constructor. A method
that will be called as a parameter from the parametrisedMethod
which is of type Function<String, Foo>
.
Function<String, Foo>
means that the function takes a String
as parameter and return a Foo
.Foo::Method
correspond to a lambda like x -> Foo.method(x);
parametrisedMethod(Foo::method)
could be seen as x -> parametrisedMethod(Foo.method(x))
.apply("from a method")
is basically to do parametrisedMethod(Foo.method("from a method"))
Which will then return in the output:
>> I'm a Foo from a method
The example should be running as is, you can then try more complicated stuff from the above answers with different classes and interfaces.
This provides you with the possibility of adding conditions on the rows and then change all the cells of a specific column corresponding to those rows:
df.loc[(df['issueid'] == '001'), 'industry'] = str('yyy')
I developed a new plugin called JavaScript Enhancements, that you can find on Package Control. It uses Flow (javascript static type checker from Facebook) under the hood.
Furthermore, it offers smart javascript autocomplete (compared to my other plugin JavaScript Completions), real-time errors, code refactoring and also a lot of features about creating, developing and managing javascript projects.
See the Wiki to know all the features that it offers!
An introduction to this plugin could be found in this css-tricks.com article: Turn Sublime Text 3 into a JavaScript IDE
Just some quick screenshots:
First, understand that you have three languages working together:
PHP: It only runs by the server and responds to requests like clicking on a link (GET) or submitting a form (POST).
HTML & JavaScript: It only runs in someone's browser (excluding NodeJS).
I'm assuming your file looks something like:
<!DOCTYPE HTML>
<html>
<?php
function runMyFunction() {
echo 'I just ran a php function';
}
if (isset($_GET['hello'])) {
runMyFunction();
}
?>
Hello there!
<a href='index.php?hello=true'>Run PHP Function</a>
</html>
Because PHP only responds to requests (GET, POST, PUT, PATCH, and DELETE via $_REQUEST), this is how you have to run a PHP function even though they're in the same file. This gives you a level of security, "Should I run this script for this user or not?".
If you don't want to refresh the page, you can make a request to PHP without refreshing via a method called Asynchronous JavaScript and XML (AJAX).
That is something you can look up on YouTube though. Just search "jquery ajax"
I recommend Laravel to anyone new to start off right: http://laravel.com/
I know this is old and whatnot (and not exactly sure if it's a question), but after searching, I had success with this command for --onefile
:
pyinstaller.exe --onefile --windowed --icon=app.ico app.py
Google led me to this page while I was searching for an answer on how to set an icon for my .exe, so maybe it will help someone else.
The information here was found at this site: https://mborgerson.com/creating-an-executable-from-a-python-script
With debounce
you need to keep the original synthetic event around with event.persist()
. Here is working example tested with React 16+
.
import React, { Component } from 'react';
import debounce from 'lodash/debounce'
class ItemType extends Component {
evntHandler = debounce((e) => {
console.log(e)
}, 500);
render() {
return (
<div className="form-field-wrap"
onClick={e => {
e.persist()
this.evntHandler(e)
}}>
...
</div>
);
}
}
export default ItemType;
With functional component, you can do this -
const Search = ({ getBooks, query }) => {
const handleOnSubmit = (e) => {
e.preventDefault();
}
const debouncedGetBooks = debounce(query => {
getBooks(query);
}, 700);
const onInputChange = e => {
debouncedGetBooks(e.target.value)
}
return (
<div className="search-books">
<Form className="search-books--form" onSubmit={handleOnSubmit}>
<Form.Group controlId="formBasicEmail">
<Form.Control type="text" onChange={onInputChange} placeholder="Harry Potter" />
<Form.Text className="text-muted">
Search the world's most comprehensive index of full-text books.
</Form.Text>
</Form.Group>
<Button variant="primary" type="submit">
Search
</Button>
</Form>
</div>

That worked for me in python3:

htmlfile = urllib.request.urlopen("http://google.com")
htmltext = htmlfile.read()
print(htmltext)
Sometimes a BEFORE
trigger can be replaced with an AFTER
one, but this doesn't appear to be the case in your situation, for you clearly need to provide a value before the insert takes place. So, for that purpose, the closest functionality would seem to be the INSTEAD OF
trigger one, as @marc_s has suggested in his comment.
Note, however, that, as the names of these two trigger types suggest, there's a fundamental difference between a BEFORE
trigger and an INSTEAD OF
one. While in both cases the trigger is executed at the time when the action determined by the statement that's invoked the trigger hasn't taken place, in case of the INSTEAD OF
trigger the action is never supposed to take place at all. The real action that you need to be done must be done by the trigger itself. This is very unlike the BEFORE
trigger functionality, where the statement is always due to execute, unless, of course, you explicitly roll it back.
But there's one other issue to address actually. As your Oracle script reveals, the trigger you need to convert uses another feature unsupported by SQL Server, which is that of FOR EACH ROW
. There are no per-row triggers in SQL Server either, only per-statement ones. That means that you need to always keep in mind that the inserted data are a row set, not just a single row. That adds more complexity, although that'll probably conclude the list of things you need to account for.
So, it's really two things to solve then:
replace the BEFORE
functionality;
replace the FOR EACH ROW
functionality.
My attempt at solving these is below:
CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
DECLARE @new_super TABLE (
super_id int
);
INSERT INTO super (subtype_discriminator)
OUTPUT INSERTED.super_id INTO @new_super (super_id)
SELECT 'SUB1' FROM INSERTED;
INSERT INTO sub (super_id)
SELECT super_id FROM @new_super;
END;
This is how the above works:
The same number of rows as being inserted into sub1
is first added to super
. The generated super_id
values are stored in a temporary storage (a table variable called @new_super
).
The newly inserted super_id
s are now inserted into sub1
.
Nothing too difficult really, but the above will only work if you have no other columns in sub1
than those you've specified in your question. If there are other columns, the above trigger will need to be a bit more complex.
The problem is to assign the new super_id
s to every inserted row individually. One way to implement the mapping could be like below:
CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
DECLARE @new_super TABLE (
rownum int IDENTITY (1, 1),
super_id int
);
INSERT INTO super (subtype_discriminator)
OUTPUT INSERTED.super_id INTO @new_super (super_id)
SELECT 'SUB1' FROM INSERTED;
WITH enumerated AS (
SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS rownum
FROM inserted
)
INSERT INTO sub1 (super_id, other columns)
SELECT n.super_id, i.other columns
FROM enumerated AS i
INNER JOIN @new_super AS n
ON i.rownum = n.rownum;
END;
As you can see, an IDENTIY(1,1)
column is added to @new_user
, so the temporarily inserted super_id
values will additionally be enumerated starting from 1. To provide the mapping between the new super_id
s and the new data rows, the ROW_NUMBER
function is used to enumerate the INSERTED
rows as well. As a result, every row in the INSERTED
set can now be linked to a single super_id
and thus complemented to a full data row to be inserted into sub1
.
Note that the order in which the new super_id
s are inserted may not match the order in which they are assigned. I considered that a no-issue. All the new super
rows generated are identical save for the IDs. So, all you need here is just to take one new super_id
per new sub1
row.
If, however, the logic of inserting into super
is more complex and for some reason you need to remember precisely which new super_id
has been generated for which new sub
row, you'll probably want to consider the mapping method discussed in this Stack Overflow question:
So imagine everyone is trying to go to the bathroom and there's only a certain number of keys to the bathroom. Now if there's not enough keys left, that person needs to wait. So think of semaphore as representing those set of keys available for bathrooms (the system resources) that different processes (bathroom goers) can request access to.
Now imagine two processes trying to go to the bathroom at the same time. That's not a good situation and semaphores are used to prevent this. Unfortunately, the semaphore is a voluntary mechanism and processes (our bathroom goers) can ignore it (i.e. even if there are keys, someone can still just kick the door open).
There are also differences between binary/mutex & counting semaphores.
Check out the lecture notes at http://www.cs.columbia.edu/~jae/4118/lect/L05-ipc.html.
With any server-side language, you will have to emit the POST variables into javascript.
.NET
var my_post_variable = '<%= Request("post_variable") %>';
Just be careful of empty values. If the variable you attempt to emit is actually empty, you will get a javascript syntax error. If you know it's a string, you should wrap it in quotes. If it's an integer, you may want to test to see if it actually exists before writing the line to javascript.
Try adding wmode, it seems to have two parameters.
&wmode=Opaque
&wmode=transparent
I can't find a technical reason why it works, or much more explanation but take at look at this query.
<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/lzQgAR_J1PI?wmode=transparent" frameborder="0" wmode="Opaque">
or this
//Fix z-index youtube video embedding
$(document).ready(function (){
$('iframe').each(function(){
var url = $(this).attr("src");
$(this).attr("src",url+"?wmode=transparent");
});
});
You can use literal quoting:
stmt := q'[insert into MY_TBL (Col) values('ER0002')]';
Documentation for literals can be found here.
Alternatively, you can use two quotes to denote a single quote:
stmt := 'insert into MY_TBL (Col) values(''ER0002'')';
The literal quoting mechanism with the Q syntax is more flexible and readable, IMO.
$("#closeLink").click(closeIt);
Let's say you want to call your function passing some args to it i.e., closeIt(1, false)
. Then, you should build an anonymous function and call closeIt
from it.
$("#closeLink").click(function() {
closeIt(1, false);
});
Python is not strongly typed in the sense of static or compile-time type checking.
Most Python code falls under so-called "Duck Typing" -- for example, you look for a method read
on an object -- you don't care if the object is a file on disk or a socket, you just want to read N bytes from it.
The "best" answer has already been submitted, but I thought I would add that you can use nested list comprehensions, as seen in the Python Tutorial.
Here is how you could get a transposed array:
def matrixTranspose( matrix ):
if not matrix: return []
return [ [ row[ i ] for row in matrix ] for i in range( len( matrix[ 0 ] ) ) ]
Multiprogramming - This term is used in the context of batch systems. You've got several programs in main memory concurrently. The CPU schedules a time for each one.
I.e. submitting multiple jobs and all of them are loaded into memory and executed according to a scheduling algorithm. Common batch system scheduling algorithms include: First-Come-First-Served, Shortest-Job-First, Shortest-Remaining-Time-Next.
Multitasking - This is basically multiprogramming in the context of a single-user interactive environment, in which the OS switches between several programs in main memory so as to give the illusion that several are running at once. Common scheduling algorithms used for multitasking are: Round-Robin, Priority Scheduling (multiple queues), Shortest-Process-Next.
Note that these solutions use the Code Igniter Active Records Class
This method uses sub queries like you wish but you should sanitize $countryId
yourself!
$this->db->select('username')
->from('user')
->where('`locationId` in', '(select `locationId` from `locations` where `countryId` = '.$countryId.')', false)
->get();
Or this method would do it using joins and will sanitize the data for you (recommended)!
$this->db->select('username')
->from('users')
->join('locations', 'users.locationid = locations.locationid', 'inner')
->where('countryid', $countryId)
->get();

The answer by @Mobilpadde is nice. But this is my solution with regex using preg_replace which might be faster according to my tests.
echo preg_replace('/<br\s?\/?>/i', "\r\n", "testing<br/><br /><BR><br>");
function function_one() {
preg_replace('/<br\s?\/?>/i', "\r\n", "testing<br/><br /><BR><br>");
}
function function_two() {
str_ireplace(['<br />','<br>','<br/>'], "\r\n", "testing<br/><br /><BR><br>");
}
function benchmark() {
$count = 10000000;
$before = microtime(true);
for ($i=0 ; $i<$count; $i++) {
function_one();
}
$after = microtime(true);
echo ($after-$before)/$i . " sec/function one\n";
$before = microtime(true);
for ($i=0 ; $i<$count; $i++) {
function_two();
}
$after = microtime(true);
echo ($after-$before)/$i . " sec/function two\n";
}
benchmark();
Results:
1.1471637010574E-6 sec/function one (preg_replace)
1.6027762889862E-6 sec/function two (str_ireplace)
Just replace and
with ,
and you're done:
try:
with open('a', 'w') as a, open('b', 'w') as b:
do_something()
except IOError as e:
print 'Operation failed: %s' % e.strerror
this will do it with just javascript - you can also put the function in a .js file and call it with onclick
//button
<div onclick="
document.forms['name_of_the_form']['name_of_the_input'].value += 'text you want to add to it'"
>button</div>
I had a similar issue with overflowing images in a flex wrapper.
Adding either flex-basis: 100%;
or flex: 1;
to the overflowing child fixed worked for me.
You can use the FromStr
trait's from_str
method, which is implemented for i32
:
let my_num = i32::from_str("9").unwrap_or(0);
You can use IIF
(I think from SQL Server 2012)
SELECT IIF(B.[STAT] IS NULL, C.[EVENT DATE]+10, '-') AS [DATE]
If it is MySql you can try
SELECT @n := @n + 1 n,
first_name,
last_name
FROM table1, (SELECT @n := 0) m
ORDER BY first_name, last_name
And for SQLServer
SELECT row_number() OVER (ORDER BY first_name, last_name) n,
first_name,
last_name
FROM table1
So, let's say you have this table:
CREATE TABLE YourTable(Col1 VARCHAR(10))
And you want to change Col1
to VARCHAR(20)
. What you need to do is this:
ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)
That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5)
, then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE
will fail.
You might try passing actual types instead of strings.
import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4']
dtypes = [datetime, datetime, str, float]
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)
But it's going to be really hard to diagnose this without any of your data to tinker with.
And really, you probably want pandas to parse the the dates into TimeStamps, so that might be:
pd.read_csv(file, sep='\t', header=None, names=headers, parse_dates=True)
I made a simple JQuery plugin for this if anyone is interested.
The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5
. From the comment you put this needed to be declared elsewhere in your code
$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider
The error was because you are trying to execute a method that does not exist.
PS C:\Users\Matt> $md5 | gm
TypeName: System.Security.Cryptography.MD5CryptoServiceProvider
Name MemberType Definition
---- ---------- ----------
Clear Method void Clear()
ComputeHash Method byte[] ComputeHash(System.IO.Stream inputStream), byte[] ComputeHash(byte[] buffer), byte[] ComputeHash(byte[] buffer, int offset, ...
The .ComputeHash()
of $md5.ComputeHash()
was the null valued expression. Typing in gibberish would create the same effect.
PS C:\Users\Matt> $bagel.MakeMeABagel()
You cannot call a method on a null-valued expression.
At line:1 char:1

PowerShell by default allows this to happen as defined its StrictMode
When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.
This happens because $cOTLdata
is not null but the index 'char_data'
does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.
To check whether the index exists or not you can use isset():
isset($cOTLdata['char_data'])
Which means the line should look something like this:
$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;
Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).
"AndroidManifest" file not changed for me and i change package name manually.

Here's a little oops that may catch some: It's pretty easy to accidentally have a filter typed in for the logcat output window (the text box with the magnifying glass) and forget about it. That which will potentially filter out all output and make it look like nothing is there.
You should always use $array[]
if possible because as the box states there is no overhead for the function call. Thus it is a bit faster than the function call.
IMPORTANT this answer is valid only for PHP 5, in PHP 7 use built-in cryptographic functions.
Here is simple but secure enough implementation:

The only way I've managed to do this is by using overflow: visible;
and width: 20000px;
on the parent element. There is no way to do this with CSS level 1 that I'm aware of and I refused to think I'd have to go all gung-ho with CSS level 3. The example below has 18 menus that extend beyond my 1920x1200 resolution LCD, if your screen is larger just duplicate the first tier menu elements or just resize the browser. Alternatively and with slightly lower levels of browser compatibility you could use CSS3 media queries.

You should place two update statements inside a transaction
As per your requirement, Thread.Sleep
is perfectly fine to use because you are not sure when the data will be available so you might need to wait for the data to become available. I have slightly changed the logic of your function this might help you little further.
string SendCmd(string cmd, string ip, int port)
{
var client = new TcpClient(ip, port);
var data = Encoding.GetEncoding(1252).GetBytes(cmd);
var stm = client.GetStream();
stm.Write(data, 0, data.Length);
byte[] resp = new byte[2048];
var memStream = new MemoryStream();
int bytes = 0;
do
{
bytes = 0;
while (!stm.DataAvailable)
Thread.Sleep(20); // some delay
bytes = stm.Read(resp, 0, resp.Length);
memStream.Write(resp, 0, bytes);
}
while (bytes > 0);
return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}
Hope this helps!
You'll want something like this to increase the message size quotas, in the App.config or Web.config file:
<bindings>
<basicHttpBinding>
<binding name="basicHttp" allowCookies="true"
maxReceivedMessageSize="20000000"
maxBufferSize="20000000"
maxBufferPoolSize="20000000">
<readerQuotas maxDepth="32"
maxArrayLength="200000000"
maxStringContentLength="200000000"/>
</binding>
</basicHttpBinding>
</bindings>
And use the binding name in your endpoint configuration e.g.
...
bindingConfiguration="basicHttp"
...
The justification for the values is simple, they are sufficiently large to accommodate most messages. You can tune that number to fit your needs. The low default value is basically there to prevent DOS type attacks. Making it 20000000 would allow for a distributed DOS attack to be effective, the default size of 64k would require a very large number of clients to overpower most servers these days.
export class Car {
id: number;
make: string;
model: string;
color: string;
year: Date;
constructor(car) {
{
this.id = car.id;
this.make = car.make || '';
this.model = car.model || '';
this.color = car.color || '';
this.year = new Date(car.year).getYear();
}
}
}
The || can become super useful for very complex data objects to default data that doesn't exist.
. .
In your component.ts or service.ts file you can deserialize response data into the model:
// Import the car model
import { Car } from './car.model.ts';
// If single object
car = new Car(someObject);
// If array of cars
cars = someDataToDeserialize.map(c => new Car(c));
Select isnull(date_column_name,cast('1900-01-01' as DATE)) from table name
I am not pro in Java but your problem can be solved by "blockingqueue" if you use it wisely.
Try to retrieve a chunk of records first, process them, and iterate the process until you complete your processing. This may help you to get rid of the OutOfMemory Exceptions
.
It should help you.

in my project name e.g 'HKUSTx:part-2' renaming it 'HKUSTx-part-2' worked for me
Have a look at the following apache commons function:
org.apache.commons.io.FileUtils.readFileToByteArray(File)
When I switched careers out of Finance, I took 9 months off to study C++ full-time out of a book by Ivor Horton. I had a lot of support from my best friend, who is a guru, and I had been programming as a hobby since high school (I was 36 at the time).
It's not just the syntax that's an issue. The idea of things like pointers, passing by reference, multi-tiered architectures, struct's vs classes, etc., these all take time to understand and learn to use. And you're adding to that the .Net framework, which is huge and constantly evolving, and SQL, which is a totally different skill set than C#. You also haven't mentioned various subsets of the framework that are becoming more widely used, like WPF, WCF, WF, etc.
You're an academic so you can definitely do it, but it's going to take serious effort for a long time, and you definitely will need some projects to work on and learn from. Good luck to you.
I am using in the following case: In UI I got an action from a button, for eg. the user want to download an 500mb file. Thank I will initialize the background engine (AsyncTask class) and pass parameters to him. On the UI I will show a blocking progress dialog and disable the user to make any other clicks. The question is: when to remove the blocking from UI? the answer is: when the engine finished with success or fail, and that can be with callbacks or notifications.
What is the difference between notification and callbacks it is another question, but 1:1 is faster the callback.
AdaTheDEV, I used your syntax and created the following and why.
Problem: Process runs once a quarter taking an hour due to missing index.
Correction: Alter query process or Procedure to check for index and create it if missing... Same code is placed at the end of the query and procedure to remove index since it is not needed but quarterly. Showing Only drop syntax here
-- drop the index
begin
IF EXISTS (SELECT * FROM sys.indexes WHERE name='Index_Name'
AND object_id = OBJECT_ID('[SchmaName].[TableName]'))
begin
DROP INDEX [Index_Name] ON [SchmaName].[TableName];
end
end
You can try this function
/**
* Gets the request parameter.
*
* @param string $key The query parameter
* @param string $default The default value to return if not found
*
* @return string The request parameter.
*/
function get_request_parameter( $key, $default = '' ) {
// If not request set
if ( ! isset( $_REQUEST[ $key ] ) || empty( $_REQUEST[ $key ] ) ) {
return $default;
}
// Set so process it
return strip_tags( (string) wp_unslash( $_REQUEST[ $key ] ) );
}
Here is what is happening in the function
Here three things are happening.
All of this information plus more info on the thinking behind the function can be found on this link https://www.intechgrity.com/correct-way-get-url-parameter-values-wordpress/
I was also facing this issue but in a little different scenario.
Scenario:
param = 1
def param():
.....
def func():
if param:
var = {passing a dict here}
param(var)
It looks simple and a stupid mistake here, but due to multiple lines of codes in the actual code, it took some time for me to figure out that the variable name I was using was same as my function name because of which I was getting this error.
Changed function name to something else and it worked.
So, basically, according to what I understood, this error means that you are trying to use an integer as a function or in more simple terms, the called function name is also used as an integer somewhere in the code. So, just try to find out all occurrences of the called function name and look if that is being used as an integer somewhere.
I struggled to find this, so, sharing it here so that someone else may save their time, in case if they get into this issue.
Hope this helps!
These are the prerequisites of directly using the script name:
#!/bin/bash
) at the very top.chmod u+x scriptname
to make the script executable (where scriptname
is the name of your script)./usr/local/bin
folder.
/usr/local/bin
because most likely that path will be already added to your PATH
variable.scriptname
.If you don't have access to /usr/local/bin
then do the following:
Create a folder in your home directory and call it bin
.
Do ls -lA
on your home directory, to identify the start-up script your shell is using. It should be either .profile
or .bashrc
.
Once you have identified the start up script, add the following line:
PATH="$PATH:$HOME/bin"
Once added, source your start-up script or log out and log back in.
To source, put .
followed by a space and then your start-up script name, e.g. . .profile
or . .bashrc
Run the script using just its name, scriptname
.
Here's the quick and dirty way.
// Add $injector as a parameter for your controller
function myAngularController($scope,$injector){
$scope.sendorders = function(){
// now you can use $injector to get the
// handle of $rootScope and broadcast to all
$injector.get('$rootScope').$broadcast('sinkallships');
};
}
Here is an example function to add within any of the sibling controllers:
$scope.$on('sinkallships', function() {
alert('Sink that ship!');
});
and of course here's your HTML:
<button ngclick="sendorders()">Sink Enemy Ships</button>
This was a really a helpful thread, I followed the same steps as @junjie mentioned but for me something weird happened, the below are the steps I did.
If Xcode detects an issue with a signing identity, it displays an appropriate action in Accounts preferences. If Xcode displays a Create button, the signing identity doesn’t exist in Member Center or on your Mac. If Xcode displays a Reset button, the signing identity is not usable on your Mac—for example, it is missing the private key. If you click the Reset button, Xcode revokes and requests the corresponding certificate.
You can also add
<Resource
auth="Container"
driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
maxActive="20"
maxIdle="10"
maxWait="-1"
name="ds/flexeraDS"
type="javax.sql.DataSource"
url="jdbc:derby:flexeraDB;create=true"
/>
under META-INF/context.xml
file (This will be only at application level).
Yes, but not how you would imagine. According to caniuse (a very good resource) there is no support and no polyfill available for adding text-shadow
support to IE9. However, IE has their own proprietary text shadow (detailed here).
Example implementation, taken from their website (works in IE5.5 through IE9):
p.shadow {
filter: progid:DXImageTransform.Microsoft.Shadow(color=#0000FF,direction=45);
}
For cross-browser compatibility and future-proofing of code, remember to also use the CSS3 standard text-shadow
property (detailed here). This is especially important considering that IE10 has officially announced their intent to drop support for legacy dx filters. Going forward, IE10+ will only support the CSS3 standard text-shadow
.
That should be simple. Try this:
var idList = new int[1, 2, 3, 4, 5];
var userProfiles = _dataContext.UserProfile.Where(e => idList.Contains(e));
I found a more recent blog post in Anaconda which instructs how to install the TF easily. I used:
conda create -n tensorflow_env tensorflow
Or for the GPU version (Make sure that you have NVIDIA GPU)
conda create -n tensorflow_gpuenv tensorflow-gpu
This way you will have different environments for different TFs.
It's an option that you pass to the read()
command:
context = new org.apache.spark.sql.SQLContext(sc)
var data = context.read.option("header","true").csv("<path>")
I've found this script example useful (from http://www.mrexcel.com/forum/excel-questions/898899-json-api-excel.html#post4332075 ):
Sub getData()
Dim Movie As Object
Dim scriptControl As Object
Set scriptControl = CreateObject("MSScriptControl.ScriptControl")
scriptControl.Language = "JScript"
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", "http://www.omdbapi.com/?t=frozen&y=&plot=short&r=json", False
.send
Set Movie = scriptControl.Eval("(" + .responsetext + ")")
.abort
With Sheets(2)
.Cells(1, 1).Value = Movie.Title
.Cells(1, 2).Value = Movie.Year
.Cells(1, 3).Value = Movie.Rated
.Cells(1, 4).Value = Movie.Released
.Cells(1, 5).Value = Movie.Runtime
.Cells(1, 6).Value = Movie.Director
.Cells(1, 7).Value = Movie.Writer
.Cells(1, 8).Value = Movie.Actors
.Cells(1, 9).Value = Movie.Plot
.Cells(1, 10).Value = Movie.Language
.Cells(1, 11).Value = Movie.Country
.Cells(1, 12).Value = Movie.imdbRating
End With
End With
End Sub
and to get it :
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.d(getLocalClassName(), "onItemClick(" + view + ","
+ position + "," + id + ")");
}
});
The original order is in fact backwards. Certs should be followed by the issuing cert until the last cert is issued by a known root per IETF's RFC 5246 Section 7.4.2
This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it.
See also SSL: error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch for troubleshooting techniques.
But I still don't know why they wrote the spec so that the order matters.
