Another method using DATEPART
built-in function:
SELECT cast(DATEPART(hour, GETDATE()) as varchar) + ':' + cast(DATEPART(minute, GETDATE()) as varchar)
The message is clear: you have a repeated column in the mapping. That means you mapped the same database column twice. And indeed, you have:
@Column(nullable=false)
private Long customerId;
and also:
@ManyToOne(optional=false)
@JoinColumn(name="customerId",referencedColumnName="id_customer")
private Customer customer;
(and the same goes for productId
/product
).
You shouldn't reference other entities by their ID, but by a direct reference to the entity. Remove the customerId
field, it's useless. And do the same for productId
. If you want the customer ID of a sale, you just need to do this:
sale.getCustomer().getId()
To create multiple sub-folders
mkdir -p parentfolder/{subfolder1,subfolder2,subfolder3}
I hope that the below answer may be efficient and also simple:
$content = "The main string to search";
$search = "T";
//For compare the begining string with case insensitive.
if(stripos($content, $search) === 0) echo 'Yes';
else echo 'No';
//For compare the begining string with case sensitive.
if(strpos($content, $search) === 0) echo 'Yes';
else echo 'No';
//For compare the ending string with case insensitive.
if(stripos(strrev($content), strrev($search)) === 0) echo 'Yes';
else echo 'No';
//For compare the ending string with case sensitive.
if(strpos(strrev($content), strrev($search)) === 0) echo 'Yes';
else echo 'No';
Can't you originally get the data as a JSONObject?
Perhaps parse the string as both a JSONObject and a JSONArray in the first place? Where is the JSON string coming from?
I'm not sure that it is possible to convert a JsonArray into a JsonObject.
I presume you are using the following from json.org
JSONObject.java
A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having get() and opt() methods for accessing the values by name, and put() methods for adding or replacing values by name. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.
JSONArray.java
A JSONArray is an ordered sequence of values. Its external form is a string wrapped in square brackets with commas between the values. The internal form is an object having get() and opt() methods for accessing the values by index, and put() methods for adding or replacing values. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.
To get the behavior you want you need to wait for the process to finish before you exit Main()
. To be able to tell when your process is done you need to return a Task
instead of a void
from your function, you should never return void
from a async
function unless you are working with events.
A re-written version of your program that works correctly would be
class Program { static void Main(string[] args) { Debug.WriteLine("Calling DoDownload"); var downloadTask = DoDownloadAsync(); Debug.WriteLine("DoDownload done"); downloadTask.Wait(); //Waits for the background task to complete before finishing. } private static async Task DoDownloadAsync() { WebClient w = new WebClient(); string txt = await w.DownloadStringTaskAsync("http://www.google.com/"); Debug.WriteLine(txt); } }
Because you can not await
in Main()
I had to do the Wait()
function instead. If this was a application that had a SynchronizationContext I would do await downloadTask;
instead and make the function this was being called from async
.
Change the names of your inputs:
<input name="xyz[]" value="Lorem" />
<input name="xyz[]" value="ipsum" />
<input name="xyz[]" value="dolor" />
<input name="xyz[]" value="sit" />
<input name="xyz[]" value="amet" />
Then:
$_POST['xyz'][0] == 'Lorem'
$_POST['xyz'][4] == 'amet'
If so, that would make my life ten times easier, as I could send an indefinite amount of information through a form and get it processed by the server simply by looping through the array of items with the name "xyz".
Note that this is probably the wrong solution. Obviously, it depends on the data you are sending.
BTW you can pass the error message directly to sys.exit:
if len(sys.argv) < 2:
sys.exit('Usage: %s database-name' % sys.argv[0])
if not os.path.exists(sys.argv[1]):
sys.exit('ERROR: Database %s was not found!' % sys.argv[1])
When filtering a DataFrame with string values, I find that the pyspark.sql.functions
lower
and upper
come in handy, if your data could have column entries like "foo" and "Foo":
import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))
I've got this working after doing the following:
Note: This doesn't give me the runtime exceptions either, it works.
import sys
sys.exit(1)
If you have the flutter SDK installed.
Run:
flutter doctor -v
The first line will show the install path..
(if you don't have it installed go to the documentation)
I'm not sure if this has been changed, or if it has something to do with which version of PS you're using, but using Andy's example, I can remove the -Name parameter and I still get the value of the reg item:
PS C:\> $key = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion'
PS C:\> (Get-ItemProperty -Path $key).ProgramFilesDir
C:\Program Files
PS C:\> $psversiontable.psversion

Scikit learn plays really well with Pandas, so I suggest you use it. Here's an example:
In [1]:
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
data = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
labels = np.random.randint(2, size=10) # 10 labels
In [2]: # Giving columns in X a name
X = pd.DataFrame(data, columns=['Column_1', 'Column_2'])
y = pd.Series(labels)
In [3]:
X_train, X_test, y_train, y_test = train_test_split(X, y,
test_size=0.2,
random_state=0)
In [4]: X_test
Out[4]:
Column_1 Column_2
2 -1.39 -1.86
8 0.48 -0.81
4 -0.10 -1.83
In [5]: y_test
Out[5]:
2 1
8 1
4 1
dtype: int32
You can directly call any scikit functions on DataFrame/Series and it will work.
Let's say you wanted to do a LogisticRegression, here's how you could retrieve the coefficients in a nice way:
In [6]:
from sklearn.linear_model import LogisticRegression
model = LogisticRegression()
model = model.fit(X_train, y_train)
# Retrieve coefficients: index is the feature name (['Column_1', 'Column_2'] here)
df_coefs = pd.DataFrame(model.coef_[0], index=X.columns, columns = ['Coefficient'])
df_coefs
Out[6]:
Coefficient
Column_1 0.076987
Column_2 -0.352463
setDatabasePath() method was deprecated in API level 19. I advise you to use storage locale like this:
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");
}
NOTE: I am sharing this. It is not mean that here is not good answer but because I easily understood.
Answer:
When a class is conceptualized, what are the properties we can have in it given the context. If we are designing a class Animal in the context of a zoo, it is important that we have an attribute as animalType to describe domestic or wild. This attribute may not make sense when we design the class in a different context.
Similarly, what are the behaviors we are going to have in the class? Abstraction is also applied here. What is necessary to have here and what will be an overdose? Then we cut off some information from the class. This process is applying abstraction.
When we ask for difference between encapsulation and abstraction, I would say, encapsulation uses abstraction as a concept. So then, is it only encapsulation. No, abstraction is even a concept applied as part of inheritance and polymorphism.
Go here for more explanation about this topic.
People say you can't and I understand you may be frustrated when asking a question and getting such an answer.
If you really want it to show in UTF-8 instead of US ASCII then you need to do it in two steps.
First:
iconv -f us-ascii -t utf-16 yourfile > youfileinutf16.*
Second:
iconv -f utf-16le -t utf-8 yourfileinutf16 > yourfileinutf8.*
Then if you do a file -i
, you'll see the new character set is UTF-8.
Why don't you $.post
or $.get
directly?
GET
requests:
$.get(url, data, callback);
POST
requests:
$.post(url, data, callback);
Then you don't need a form, just send the data in your data object.
$.post("form2.html", {myField: "some value"}, function(){
alert("done!");
});
Many of these answers were quite useful to me in the past, but I would like to add an additional scenario that has cost me some time, as it may help others in the future:
Make sure that the test classes and methods are public.
My problem was that I was using an automatic test class/methods generation feature of my IDE (IntelliJ) and for some reason it created them as package-private. I find this to be easier to miss than one would expect.
This only works for powers of two (and frequently only positive ones) because they have the unique property of having only one bit set to '1' in their binary representation. Because no other class of numbers shares this property, you can't create bitwise-and expressions for most modulus expressions.
Try this
public static void main(String[] args)
{
String original = "ABCDEFGHIJKLMNOPQ";
String tobeChecked = "GHi";
System.out.println(containsString(original, tobeChecked, true));
System.out.println(containsString(original, tobeChecked, false));
}
public static boolean containsString(String original, String tobeChecked, boolean caseSensitive)
{
if (caseSensitive)
{
return original.contains(tobeChecked);
}
else
{
return original.toLowerCase().contains(tobeChecked.toLowerCase());
}
}
You could use Hortonworks spark-llap library like this
import com.hortonworks.hwc.HiveWarehouseSession
df.write
.format("com.hortonworks.spark.sql.hive.llap.HiveWarehouseConnector")
.mode("append")
.option("table", "myDatabase.myTable")
.save()
Yes, just format your strings in the standard String.format()
way.
See the method Context.getString(int, Object...)
and the Android or Java Formatter
documentation.
In your case, the string definition would be:
<string name="timeFormat">%1$d minutes ago</string>
One thing you should know is $ prefix refers to an Angular Method, $$ prefixes refers to angular methods that you should avoid using.
below is an example template and its controllers, we'll explore how $broadcast/$on can help us achieve what we want.
<div ng-controller="FirstCtrl">
<input ng-model="name"/>
<button ng-click="register()">Register </button>
</div>
<div ng-controller="SecondCtrl">
Registered Name: <input ng-model="name"/>
</div>
The controllers are
app.controller('FirstCtrl', function($scope){
$scope.register = function(){
}
});
app.controller('SecondCtrl', function($scope){
});
My question to you is how do you pass the name to the second controller when a user clicks register? You may come up with multiple solutions but the one we're going to use is using $broadcast and $on.
$broadcast vs $emit
Which should we use? $broadcast will channel down to all the children dom elements and $emit will channel the opposite direction to all the ancestor dom elements.
The best way to avoid deciding between $emit or $broadcast is to channel from the $rootScope and use $broadcast to all its children. Which makes our case much easier since our dom elements are siblings.
Adding $rootScope and lets $broadcast
app.controller('FirstCtrl', function($rootScope, $scope){
$scope.register = function(){
$rootScope.$broadcast('BOOM!', $scope.name)
}
});
Note we added $rootScope and now we're using $broadcast(broadcastName, arguments). For broadcastName, we want to give it a unique name so we can catch that name in our secondCtrl. I've chosen BOOM! just for fun. The second arguments 'arguments' allows us to pass values to the listeners.
Receiving our broadcast
In our second controller, we need to set up code to listen to our broadcast
app.controller('SecondCtrl', function($scope){
$scope.$on('BOOM!', function(events, args){
console.log(args);
$scope.name = args; //now we've registered!
})
});
It's really that simple. Live Example
Other ways to achieve similar results
Try to avoid using this suite of methods as it is neither efficient nor easy to maintain but it's a simple way to fix issues you might have.
You can usually do the same thing by using a service or by simplifying your controllers. We won't discuss this in detail but I thought I'd just mention it for completeness.
Lastly, keep in mind a really useful broadcast to listen to is '$destroy' again you can see the $ means it's a method or object created by the vendor codes. Anyways $destroy is broadcasted when a controller gets destroyed, you may want to listen to this to know when your controller is removed.
There are lots of good answers already for this question. However nowadays Route configuration is sort of "deprecated". The newer version of MVC (.NET Core) does not support it. So better to get use to it :)
So I agree with all the answers which uses Attribute style routing. But I keep noticing that everyone repeated the base part of the route (api/...). It is better to apply a [RoutePrefix] attribute on top of the Controller class and don't repeat the same string over and over again.
[RoutePrefix("api/customers")]
public class MyController : Controller
{
[HttpGet]
public List<Customer> Get()
{
//gets all customer logic
}
[HttpGet]
[Route("currentMonth")]
public List<Customer> GetCustomerByCurrentMonth()
{
//gets some customer
}
[HttpGet]
[Route("{id}")]
public Customer GetCustomerById(string id)
{
//gets a single customer by specified id
}
[HttpGet]
[Route("customerByUsername/{username}")]
public Customer GetCustomerByUsername(string username)
{
//gets customer by its username
}
}
Insert into = Adding rows to a table
Upate = update specific rows.
What would the where clause describe in your insert? It doesn't have anything to match, the row doesn't exist (yet)...
This is now possible with JPA 2.1:
@Column(name = "RIGHT")
@Enumerated(EnumType.STRING)
private Right right;
Further details:
I could find all parameters by using following code for both POST and GET requests.
var express = require('express');
var app = express();
const util = require('util');
app.post('/', function (req, res) {
console.log("Got a POST request for the homepage");
res.send(util.inspect(req.query,false,null));
})
The tidyverse
version is this:

2 0.3721239 37.212%
3 0.5728534 57.285%
4 0.9082078 90.821%
5 0.2016819 20.168%
Looks tidy as usual.

If you're thinking about manually removing Apple's default Python 2.7, I'd suggest you hang-fire and do-noting: Looks like Apple will very shortly do it for you:
Python 2.7- as well as Ruby & Perl- are deprecated in Catalina: (skip to section "Scripting Language Runtimes" > "Deprecations")
https://developer.apple.com/documentation/macos_release_notes/macos_catalina_10_15_release_notes
Indeed, if you do nothing at all, according to The Mac Observer, by OSX version 10.16, Python 2.7 will disappear from your system:
https://www.macobserver.com/analysis/macos-catalina-deprecates-unix-scripting-languages/
Given this revelation, I'd suggest the best course of action is do nothing and wait for Apple to wipe it for you. As Apple is imminently about to remove it for you, doesn't seem worth the risk of tinkering with your Python environment.
NOTE: I see the question relates specifically to OSX v 10.6.4, but it appears this question has become a pivot-point for all OSX folks interested in removing Python 2.7 from their systems, whatever version they're running.
Thanks Andy for the example, this was very helpful. I ended implementing a slightly different strategy since I am developing a single-page scroll and did not want Angular to refresh when using the hashbang URL. I also want to preserve the back/forward action of the browser.
Instead of using the directive and the hash, I am using a $scope.$watch on the $location.search, and obtaining the target from there. This gives a nice clean anchor tag
<a ng-href="#/?scroll=myElement">My element</a>
I chained the watch code to the my module declaration in app.js like so:
.run(function($location, $rootScope) {
$rootScope.$watch(function() { return $location.search() }, function(search) {
var scrollPos = 0;
if (search.hasOwnProperty('scroll')) {
var $target = $('#' + search.scroll);
scrollPos = $target.offset().top;
}
$("body,html").animate({scrollTop: scrollPos}, "slow");
});
})
The caveat with the code above is that if you access by URL directly from a different route, the DOM may not be loaded in time for jQuery's $target.offset() call. The solution is to nest this code within a $viewContentLoaded watcher. The final code looks something like this:
.run(function($location, $rootScope) {
$rootScope.$on('$viewContentLoaded', function() {
$rootScope.$watch(function() { return $location.search() }, function(search) {
var scrollPos = 0
if (search.hasOwnProperty('scroll')) {
var $target = $('#' + search.scroll);
var scrollPos = $target.offset().top;
}
$("body,html").animate({scrollTop: scrollPos}, "slow");
});
});
})
Tested with Chrome and FF
This is old question but in my case...
- (void) scrollViewWillBeginDragging:(UIScrollView *)scrollView {
_m_offsetIdx = [m_cv indexPathForCell:m_cv.visibleCells.firstObject].row;
}
- (void) scrollViewDidEndDecelerating:(UIScrollView *)scrollView {
_m_offsetIdx = [m_cv indexPathForCell:m_cv.visibleCells.lastObject].row;
}

After struggling with various page-break settings and heights and a million various CSS rules on the body tag, I finally solved it over a year later.
I have a div which is supposed to be the only thing on the page which prints, but I was getting several blank pages after it.
My body tag is set to visibility:hidden;
but that wasn't enough. Vertically tall page elements still take up 'space'. So I added this in my print CSS rules:
#header, #menu, #sidebar{ height:1px; display:none;}
to target specific divs by their ids which contain tall page layout elements. I shrunk the height and then removed them from the layout. No more blank pages. Years later I'm happy to tell my client I cracked it. Hope this helps someone.
If your experiencing the same problem while querying a DB2 database, you'll need to use the below query.
SELECT *
FROM OPENQUERY(LINK_DB,'SELECT
CITY,
cast(STATE as varchar(40))
FROM DATABASE')
From See Java Static Variable Methods:
- It is a variable which belongs to the class and not to object(instance)
- Static variables are initialized only once , at the start of the execution. These variables will be initialized first, before the initialization of any instance variables
- A single copy to be shared by all instances of the class
- A static variable can be accessed directly by the class name and doesn’t need any object.
Instance and class (static) variables are automatically initialized to standard default values if you fail to purposely initialize them. Although local variables are not automatically initialized, you cannot compile a program that fails to either initialize a local variable or assign a value to that local variable before it is used.
What the compiler actually does is to internally produce a single class initialization routine that combines all the static variable initializers and all of the static initializer blocks of code, in the order that they appear in the class declaration. This single initialization procedure is run automatically, one time only, when the class is first loaded.
In case of inner classes, they can not have static fields
An inner class is a nested class that is not explicitly or implicitly declared
static
....
Inner classes may not declare static initializers (§8.7) or member interfaces...
Inner classes may not declare static members, unless they are constant variables...
See JLS 8.1.3 Inner Classes and Enclosing Instances
final
fields in Java can be initialized separately from their declaration place this is however can not be applicable to static final
fields. See the example below.
final class Demo
{
private final int x;
private static final int z; //must be initialized here.
static
{
z = 10; //It can be initialized here.
}
public Demo(int x)
{
this.x=x; //This is possible.
//z=15; compiler-error - can not assign a value to a final variable z
}
}
This is because there is just one copy of the static
variables associated with the type, rather than one associated with each instance of the type as with instance variables and if we try to initialize z
of type static final
within the constructor, it will attempt to reinitialize the static final
type field z
because the constructor is run on each instantiation of the class that must not occur to static final
fields.
Add the following css class
.dropdown-menu {
width: 300px !important;
height: 400px !important;
}
Of course you can use what matches your need.
For example, if you have a users
entity you want to store, with fields (firstname, lastname , email)
and you want autogenerated id, you do this.
@Entity(tableName = "users")
data class Users(
@PrimaryKey(autoGenerate = true)
val id: Long,
val firstname: String,
val lastname: String,
val email: String
)
Room will then autogenerate and auto-increment the id
field.
Lets get a visual impression about what was already said. For example you have a table with some tasks:
SELECT a.id,a.status,a.description FROM minicloud_tasks as a ORDER BY random();
id | status | description
----+------------+------------------
4 | processing | work on postgres
6 | deleted | need some rest
3 | pending | garden party
5 | completed | work on html
And you want to order the list of tasks by its status. The status is a list of string values:
(processing, pending, completed, deleted)
The trick is to give each status value an interger and order the list numerical:
SELECT a.id,a.status,a.description FROM minicloud_tasks AS a
JOIN (
VALUES ('processing', 1), ('pending', 2), ('completed', 3), ('deleted', 4)
) AS b (status, id) ON (a.status = b.status)
ORDER BY b.id ASC;
Which leads to:
id | status | description
----+------------+------------------
4 | processing | work on postgres
3 | pending | garden party
5 | completed | work on html
6 | deleted | need some rest

Just add this in you styles.xml. The colorPrimary is for the action bar and the colorPrimaryDark is for the status bar.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:colorPrimary">@color/primary</item>
<item name="android:colorPrimaryDark">@color/primary_dark</item>
</style>
This picture from developer android explains more about color pallete. You can read more on this link.
I usually use this piece of code :
var start = new Date(timestamp),
startMinutes = start.getMinutes() < 10 ? '0' + start.getMinutes() : start.getMinutes();
It is quite similar to the @ogur accepted answer but does not concatenate an empty string in the case that 0 is not needed. Not sure it is better. Just an other way to do it !
We do it in a project running in production for months now and never had a problem so far. Keep in mind the 2 ingredients needed for this recipe:
Design your object model with a backwards-compatibility approach, that is deprecate objects and attributes rather than removing/altering them. This means that if you need to change the name of an object or attribute, leave the old one as is, add the new one and write some kind of migration script. If you need to change an association between objects, if you already are in production, this means that your design was wrong in the first place, so try to think of a new way of expressing the new relationship, without affecting old data.
Always backup the database prior to deployment.
My sense is - after reading this post - that 90% of the people taking part in this discussion are horrified just with the thought of using automations like this in a production environment. Some throw the ball at the DBA. Take a moment though to consider that not all production environments will provide a DBA and not many dev teams are able to afford one (at least for medium size projects). So, if we're talking about teams where everyone has to do everything, the ball is on them.
In this case, why not just try to have the best of both worlds? Tools like this are here to give a helping hand, which - with a careful design and plan - can help in many situations. And believe me, administrators may initially be hard to convince but if they know that the ball is not on their hands, they will love it.
Personally, I'd never go back to writing scripts by hand for extending any type of schema, but that's just my opinion. And after starting to adopt NoSQL schema-less databases recently, I can see that more than soon, all these schema-based operations will belong to the past, so you'd better start changing your perspective and look ahead.
Another option if you're using vue cli 3 is to use a config file. Make a vue.config.js
at the same level as your package.json
and put a config like so:
module.exports = {
devServer: {
port: 3000
}
}
Configuring it with the script:
npm run serve --port 3000
works great but if you have more config options I like doing it in a config file. You can find more info in the docs.
You have to specify the projectBaseDir
if the module name doesn't match you module directory.
Since both your module are located in ".", you can simply add the following to your sonar-project properties:
module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.
Sonar will handle your modules as components of the project:
EDIT
If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions
:
module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*
module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*
Another solutions are assign RangeIndex
or range
:
df.index = pd.RangeIndex(len(df.index))
df.index = range(len(df.index))
It is faster:
df = pd.DataFrame({'a':[8,7], 'c':[2,4]}, index=[7,8])
df = pd.concat([df]*10000)
print (df.head())
In [298]: %timeit df1 = df.reset_index(drop=True)
The slowest run took 7.26 times longer than the fastest. This could mean that an intermediate result is being cached.
10000 loops, best of 3: 105 µs per loop
In [299]: %timeit df.index = pd.RangeIndex(len(df.index))
The slowest run took 15.05 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 7.84 µs per loop
In [300]: %timeit df.index = range(len(df.index))
The slowest run took 7.10 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 14.2 µs per loop
found = binarySearch(first, last, search4, &random);

User1's example worked well for me. But, as a warning, it won't work with anything other than simple String/Integer types, unless you add an @XmlSeeAlso annotation:
@XmlRootElement(name = "List")
@XmlSeeAlso(MovieTicket.class)
public class MovieTicketList {
protected List<MovieTicket> list;
This works OK, although it prevents me from using a single generic list class across my entire application. It might also explain why this seemingly obvious class doesn't exist in the JAXB package.

ShellEd
Solutions below how to install ShellEd don't work for me. A lot of error on dependencies. Found solution that works for me.
System:
Linux Lubuntu 12.04
IDE:
Eclipse Kepler
In Eclipse, go to Help > Install New Software
Click Add...
Add the following Location, http://download.eclipse.org/releases/kepler, and name it "Eclipse Kepler".
Click OK.
Select the newly-created Eclipse Kepler site.
Expand the Web, XML, Java EE and OSGi Enterprise Development section at the bottom. Select WST Server Adaptors.
Click Next, and install like usual.
Restart Eclipse
Then add ShellEd repo likewise as listed above: http://sourceforge.net/projects/shelled/files/shelled/update/
And install it.
Restart Eclipse.
Also worked in Eclipse Indigo as said here: http://docs.wraithmonster.com/install-shelled
Enjoy :)
Update
S3 now offers a fully-managed SFTP Gateway Service for S3 that integrates with IAM and can be administered using aws-cli.
There are theoretical and practical reasons why this isn't a perfect solution, but it does work...
You can install an FTP/SFTP service (such as proftpd) on a linux server, either in EC2 or in your own data center... then mount a bucket into the filesystem where the ftp server is configured to chroot, using s3fs.
I have a client that serves content out of S3, and the content is provided to them by a 3rd party who only supports ftp pushes... so, with some hesitation (due to the impedance mismatch between S3 and an actual filesystem) but lacking the time to write a proper FTP/S3 gateway server software package (which I still intend to do one of these days), I proposed and deployed this solution for them several months ago and they have not reported any problems with the system.
As a bonus, since proftpd can chroot each user into their own home directory and "pretend" (as far as the user can tell) that files owned by the proftpd user are actually owned by the logged in user, this segregates each ftp user into a "subdirectory" of the bucket, and makes the other users' files inaccessible.
There is a problem with the default configuration, however.
Once you start to get a few tens or hundreds of files, the problem will manifest itself when you pull a directory listing, because ProFTPd will attempt to read the .ftpaccess
files over, and over, and over again, and for each file in the directory, .ftpaccess
is checked to see if the user should be allowed to view it.
You can disable this behavior in ProFTPd, but I would suggest that the most correct configuration is to configure additional options -o enable_noobj_cache -o stat_cache_expire=30
in s3fs:
-o stat_cache_expire
(default is no expire)specify expire time(seconds) for entries in the stat cache
Without this option, you'll make fewer requests to S3, but you also will not always reliably discover changes made to objects if external processes or other instances of s3fs are also modifying the objects in the bucket. The value "30" in my system was selected somewhat arbitrarily.
-o enable_noobj_cache
(default is disable)enable cache entries for the object which does not exist. s3fs always has to check whether file(or sub directory) exists under object(path) when s3fs does some command, since s3fs has recognized a directory which does not exist and has files or subdirectories under itself. It increases ListBucket request and makes performance bad. You can specify this option for performance, s3fs memorizes in stat cache that the object (file or directory) does not exist.
This option allows s3fs to remember that .ftpaccess
wasn't there.
Unrelated to the performance issues that can arise with ProFTPd, which are resolved by the above changes, you also need to enable -o enable_content_md5
in s3fs.
-o enable_content_md5
(default is disable)verifying uploaded data without multipart by content-md5 header. Enable to send "Content-MD5" header when uploading a object without multipart posting. If this option is enabled, it has some influences on a performance of s3fs when uploading small object. Because s3fs always checks MD5 when uploading large object, this option does not affect on large object.
This is an option which never should have been an option -- it should always be enabled, because not doing this bypasses a critical integrity check for only a negligible performance benefit. When an object is uploaded to S3 with a Content-MD5:
header, S3 will validate the checksum and reject the object if it's corrupted in transit. However unlikely that might be, it seems short-sighted to disable this safety check.
Quotes are from the man page of s3fs. Grammatical errors are in the original text.
Create a file in C:\Users\USERNAME which is called config.bashrc, containing:
PATH=$PATH:/c/Program\ Files\ \(x86\)/Application\ with\ space
Now move the file on the command line to the correct location:
mv config.bashrc .bashrc
The issue occurred in my case because spring framework couldn't fetch the properties of nested objects. Getters/Setters is one way of solving. Making the properties public is another quick and dirty solution to validate if this is indeed the problem.
There are no limits to the number of objects you can store in your S3 bucket. AWS claims it to have unlimited storage. However, there are some limitations -
That being said if you really have a lot of objects to be stored in S3 bucket consider randomizing your object name prefix to improve performance.
When your workload is a mix of request types, introduce some randomness to key names by adding a hash string as a prefix to the key name. By introducing randomness to your key names the I/O load will be distributed across multiple index partitions. For example, you can compute an MD5 hash of the character sequence that you plan to assign as the key and add 3 or 4 characters from the hash as a prefix to the key name.

Since ObjC 2.0, Objective-C exceptions are no longer a wrapper for C's setjmp() longjmp(), and are compatible with C++ exception, the @try is "free of charge", but throwing and catching exceptions is way more expensive.
Anyway, assertions (using NSAssert and NSCAssert macro family) throw NSException, and that sane to use them as Ries states.
You could do something like this
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:6740/api/Membership/exist");
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = 6;
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
And then strReponse should contain the values returned by your webservice
Use the example of Syed Raza Mehdi and add on the Application theme
the name=actionOverflowButtonStyle
parameter for compatibility.
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
<!-- For compatibility -->
<item name="actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>
Actually, I think the problem is that your variable "lines" is bad. You defined lines as a tuple, but I believe that write() requires a string. All you have to change is your commas into pluses (+).
nl = "\n"
lines = line1+nl+line2+nl+line3+nl
textdoc.writelines(lines)
should work.
For the Swift way of doing things, you can try and make use of the tools available in the Swift Standard Library. These should work on any platform that is able to run Swift.
Instead of floor()
, round()
and the rest of the rounding routines you can use rounded(_:)
:
let x = 6.5
// Equivalent to the C 'round' function:
print(x.rounded(.toNearestOrAwayFromZero))
// Prints "7.0"
// Equivalent to the C 'trunc' function:
print(x.rounded(.towardZero))
// Prints "6.0"
// Equivalent to the C 'ceil' function:
print(x.rounded(.up))
// Prints "7.0"
// Equivalent to the C 'floor' function:
print(x.rounded(.down))
// Prints "6.0"
These are currently available on Float
and Double
and it should be easy enough to convert to a CGFloat
for example.
Instead of sqrt()
there's the squareRoot()
method on the FloatingPoint protocol. Again, both Float
and Double
conform to the FloatingPoint
protocol:
let x = 4.0
let y = x.squareRoot()
For the trigonometric functions, the standard library can't help, so you're best off importing Darwin on the Apple platforms or Glibc on Linux. Fingers-crossed they'll be a neater way in the future.
#if os(OSX) || os(iOS)
import Darwin
#elseif os(Linux)
import Glibc
#endif
let x = 1.571
print(sin(x))
// Prints "~1.0"
Use the following snippet to add a Switch to your layout via XML:
<Switch
android:id="@+id/on_off_switch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="OFF"
android:textOn="ON"/>
Then in your Activity's onCreate method, get a reference to your Switch and set its OnCheckedChangeListener:
Switch onOffSwitch = (Switch) findViewById(R.id.on_off_switch);
onOffSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
Log.v("Switch State=", ""+isChecked);
}
});
DON'T be tempted to do things like this:
Select * from [User] U where convert(varchar(10),U.DateCreated, 120) = '2014-02-07'
This is a better way:
Select * from [User] U
where U.DateCreated >= '2014-02-07' and U.DateCreated < dateadd(day,1,'2014-02-07')
see: What does the word “SARGable” really mean?
EDIT + There are 2 fundamental reasons for avoiding use of functions on data in the where clause (or in join conditions).
2014-02-07
. It is far more efficient to alter the criteria to suit the data instead. "Amending the criteria to suit the data" is my way of describing "use SARGABLE
predicates"
And do not use between either.
the best practice with date and time ranges is to avoid BETWEEN and to always use the form:
WHERE col >= '20120101' AND col < '20120201' This form works with all types and all precisions, regardless of whether the time part is applicable.

If someone is facing issue using texttocolumns function in UFT. Please try using below function.
myxl.Workbooks.Open myexcel.xls
myxl.Application.Visible = false `enter code here`
set mysheet = myxl.ActiveWorkbook.Worksheets(1)
Set objRange = myxl.Range("A1").EntireColumn
Set objRange2 = mysheet.Range("A1")
objRange.TextToColumns objRange2,1,1, , , , true
Here we are using coma(,) as delimiter.
you can use @see
to do that:
sample:
interface View {
/**
* @return true: have read contact and call log permissions, else otherwise
* @see #requestReadContactAndCallLogPermissions()
*/
boolean haveReadContactAndCallLogPermissions();
/**
* if not have permissions, request to user for allow
* @see #haveReadContactAndCallLogPermissions()
*/
void requestReadContactAndCallLogPermissions();
}
I had the same problem in my tomcat server but when i check deeply i found that i add a new tag in my web.xml file and the server doesn't accept it so check your file to if any update happened then restart your tomcat and will be good .
Go to %ORACLE_HOME%\inventory\ContentsXML
folder and open

In my case (Win8.1, TortoiseGit running), it was the process called "TortoiseSVN status cache" that was locking the file.
Killing it allowed me to run "git gc" without any more problems. The above process is fired up by TortoiseGit, so there is no need to manually restart it.
In addition to @Marek's comment about not including fixed==TRUE
, you also need to not have the spaces in your regular expression. It should be "A1|A9|A6"
.
You also mention that there are lots of patterns. Assuming that they are in a vector
toMatch <- c("A1", "A9", "A6")
Then you can create your regular expression directly using paste
and collapse = "|"
.
matches <- unique (grep(paste(toMatch,collapse="|"),
myfile$Letter, value=TRUE))
You can also get microsecond precision from the time
module using its time()
function.
(time.time()
returns the time in seconds since epoch. Its fractional part is the time in microseconds, which is what you want.)
>>> from time import time
>>> time()
... 1310554308.287459 # the fractional part is what you want.
# comparision with strftime -
>>> from datetime import datetime
>>> from time import time
>>> datetime.now().strftime("%f"), time()
... ('287389', 1310554310.287459)
Yes it should be fixed, HAXM isn't working.
HAXM sometimes works; experience with HAXM is currently sporadic across platforms.
For instance, I've got late 2009 iMac running 10.8.5 and i7 processor @2.8Ghz, Android SDK 22.6 with all the goodies updated this morning (03/05/14). API17 will build emulators with HAXM acceleration on this iMac machine, API19 chokes out.
I also have early 2013 MBP 15" Retina running 10.8.5 and i7 processor @2.7Ghz, Android SDK 22.6 with all the goodies updated this morning (03/05/14). API17 will build emulators with HAXM acceleration, API19 works great too.
Ditto for my (personal) late 2013 MBP Retina 13" with dual-core i5 and Mavericks.
There is something going on for virtualization at the chip level missing from older CPU's (even i7's) that the new API19 x86 images need for HAXM to work. If API19 is not working, give API17 or even 16 a try.
80% of the time, when folks say "daemon", they only want a server. Since the question is perfectly unclear on this point, it's hard to say what the possible domain of answers could be. Since a server is adequate, start there. If an actual "daemon" is actually needed (this is rare), read up on nohup
as a way to daemonize a server.
Until such time as an actual daemon is actually required, just write a simple server.
Also look at the WSGI reference implementation.
Also look at the Simple HTTP Server.
"Are there any additional things that need to be considered? " Yes. About a million things. What protocol? How many requests? How long to service each request? How frequently will they arrive? Will you use a dedicated process? Threads? Subprocesses? Writing a daemon is a big job.
There's now a Jackson module (for Jackson 2) specifically designed to handle Hibernate lazy initialization problems when serializing.
https://github.com/FasterXML/jackson-datatype-hibernate
Just add the dependency (note there are different dependencies for Hibernate 3 and Hibernate 4):
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-hibernate4</artifactId>
<version>2.4.0</version>
</dependency>
and then register the module when intializing Jackson's ObjectMapper:
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new Hibernate4Module());
Documentation currently isn't great. See the Hibernate4Module code for available options.
You can use Mockito.any() when arguments are arrays also. I used it like this:
verify(myMock, times(0)).setContents(any(), any());
when you add context:component-scan for the first time in an xml, the following needs to be added.

This can mean a lot of things, but the most common one is that the class contained in the file doesn't have the same name as the file itself. So, check if your class is also called HelloWorld2.

I wrote a small function that can do it, with the Web Audio API...
var beep = function(duration, type, finishedCallback) {

}
duration = +duration;
// Only 0-4 are valid types.
type = (type % 5) || 0;
if (typeof finishedCallback != "function") {
finishedCallback = function() {};
}
var ctx = new (window.audioContext || window.webkitAudioContext);
var osc = ctx.createOscillator();
osc.type = type;
osc.connect(ctx.destination);
osc.noteOn(0);
setTimeout(function() {

finishedCallback();
}, duration);
};
(I am new to Codeigniter, so I don't know if this is the best advice)
I keep publicly available files in my public folder. It is logical for them to be there, and I don't want to use Codeigniter for something I don't need to use it for.
The directory tree looks likes this:
The only files I keep in /public/ are Codeigniter's index.php, and my .htaccess file:
RewriteEngine On
RewriteBase /
RewriteRule ^css/ - [L]
RewriteRule ^img/ - [L]
RewriteRule ^js/ - [L]
RewriteRule ^index.php(.*)$ - [L]
RewriteRule ^(.*)$ /index.php?/$1 [L]
SQL Alchemy session objects have their own execute
method:
result = db.session.execute('SELECT * FROM my_table WHERE my_column = :val', {'val': 5})
All your application queries should be going through a session object, whether they're raw SQL or not. This ensures that the queries are properly managed by a transaction, which allows multiple queries in the same request to be committed or rolled back as a single unit. Going outside the transaction using the engine or the connection puts you at much greater risk of subtle, possibly hard to detect bugs that can leave you with corrupted data. Each request should be associated with only one transaction, and using db.session
will ensure this is the case for your application.
Also take note that execute
is designed for parameterized queries. Use parameters, like :val
in the example, for any inputs to the query to protect yourself from SQL injection attacks. You can provide the value for these parameters by passing a dict
as the second argument, where each key is the name of the parameter as it appears in the query. The exact syntax of the parameter itself may be different depending on your database, but all of the major relational databases support them in some form.
Assuming it's a SELECT
query, this will return an iterable of RowProxy
objects.
You can access individual columns with a variety of techniques:
for r in result:
print(r[0]) # Access by positional index
print(r['my_column']) # Access by column name as a string
r_dict = dict(r.items()) # convert to dict keyed by column names
Personally, I prefer to convert the results into namedtuple
s:
from collections import namedtuple
Record = namedtuple('Record', result.keys())
records = [Record(*r) for r in result.fetchall()]
for r in records:
print(r.my_column)
print(r)
If you're not using the Flask-SQLAlchemy extension, you can still easily use a session:
import sqlalchemy
from sqlalchemy.orm import sessionmaker, scoped_session
engine = sqlalchemy.create_engine('my connection string')
Session = scoped_session(sessionmaker(bind=engine))
s = Session()
result = s.execute('SELECT * FROM my_table WHERE my_column = :val', {'val': 5})
In my case, I'd added a framework that must be using Objective C++. I found this post:
that explained how the main.m needed to be renamed to main.mm so that the Objective-C++ classes could be compiled, too.
That fixed it for me.
You cannot use function calls in a class construction, you should initialize that value in the constructor function.
From the PHP Manual on class properties:
This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.
A working code sample:
<?php
class UserDatabaseConnection
{
public $connection;
public function __construct()
{
$this->connection = sqlite_open("[path]/data/users.sqlite", 0666);
}
public function lookupUser($username)
{
// rest of my code...
// example usage (procedural way):
$query = sqlite_exec($this->connection, "SELECT ...", $error);
// object oriented way:
$query = $this->connection->queryExec("SELECT ...", $error);
}
}
$udb = new UserDatabaseConnection;
?>
Depending on your needs, protected
or private
might be a better choice for $connection
. That protects you from accidentally closing or messing with the connection.
There's no direct equivalent of "friend" - the closest that's available (and it isn't very close) is InternalsVisibleTo. I've only ever used this attribute for testing - where it's very handy!
Example: To be placed in AssemblyInfo.cs
[assembly: InternalsVisibleTo("OtherAssembly")]
Change your HOME environment variable.

$("#item").removeClass();
Calling removeClass
with no parameters will remove all of the item's classes.
You can also use (but is not necessarily recommended, the correct way is the one above):
$("#item").removeAttr('class');
$("#item").attr('class', '');
$('#item')[0].className = '';
If you didn't have jQuery, then this would be pretty much your only option:
document.getElementById('item').className = '';
Put it in a div tag seems to be the only way to FORCE that:
<div style="vertical-align: middle"><div><input ... /></div></div>
May be other tags like span works as like div do.
For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015
and run the program in the search result.
You can now execute your command in it, for example: cl /?
You're experiencing a strict requirement of the GROUP BY clause. Every column not in the group-by clause must have a function applied to reduce all records for the matching "group" to a single record (sum, max, min, etc).
If you list all queried (selected) columns in the GROUP BY clause, you are essentially requesting that duplicate records be excluded from the result set. That gives the same effect as SELECT DISTINCT which also eliminates duplicate rows from the result set.
The browser's native JSON API may not give you back your idOld function after you call JSON.stringify, however, if can stringify your JSON yourself (maybe use Crockford's json2.js instead of browser's API), then if you have a string of JSON e.g.
var person_json = "{ \"age:\" : 20, \"isOld:\": false, isOld: function() { return this.age > 60; } }";
then you can call
eval("(" + person + ")")
, and you will get back your function in the json object.
Try:
if not "asdf" == "fdas" echo asdf
That works for me on Windows XP (I get the same error as you for the code you posted).
As an improvement to both Praveen and Tony, I use an override:
public partial class MyDatabaseEntities : DbContext
{
public override int SaveChanges()
{
try
{
return base.SaveChanges();
}
catch (DbEntityValidationException dbEx)
{
foreach (var validationErrors in dbEx.EntityValidationErrors)
{
foreach (var validationError in validationErrors.ValidationErrors)
{
Trace.TraceInformation("Class: {0}, Property: {1}, Error: {2}",
validationErrors.Entry.Entity.GetType().FullName,
validationError.PropertyName,
validationError.ErrorMessage);
}
}
throw; // You can also choose to handle the exception here...
}
}
}
You are going to have to expose and endpoint (URL) in your system which will accept the POST request from the ajax call in jQuery.
Then, when processing that url from PHP, you would call your function and return the result in the appropriate format (JSON most likely, or XML if you prefer).
This functionality hasn't been there your whole life. It's been supported in Visual Studio since the 2010 version. It's a new C++11 feature, so it's not exclusive to Visual Studio and is/will be portable. Most compilers support it already.
You May use first split and rejoin it using white space. it will work sure.

I was answering a similar question post but the poster deleted it before i could post. Here is one example to illustrate the differences.
Python libraries may have one or more files (modules). For exmaples,
package1
|-- __init__.py
or
package2
|-- __init__.py
|-- module1.py
|-- module2.py
We can define python functions or classes inside any of the files based design requirements.
Let's define
func1()
in __init__.py
under mylibrary1
, andfoo()
in module2.py
under mylibrary2
.We can access func1()
using one of these methods
import package1
package1.func1()
or
import package1 as my
my.func1()
or
from package1 import func1
func1()
or
from package1 import *
func1()
We can use one of these methods to access foo()
:
import package2.module2
package2.module2.foo()
or
import package2.module2 as mod2
mod2.foo()
or
from package2 import module2
module2.foo()
or
from package2 import module2 as mod2
mod2.foo()
or
from package2.module2 import *
foo()
Try setting: "AllowOverride All".

Here is a lower level solution :
exec(open("MyClass.py").read(), globals())
The word "read" is vague, but here is an example which reads a jpeg file using the Image class, and prints information about it.
from PIL import Image
jpgfile = Image.open("picture.jpg")
print(jpgfile.bits, jpgfile.size, jpgfile.format)
I had this challenge when working on a Rails 6 API application in Ubuntu 20.04.
I had already existing models, and I needed to generate corresponding controllers for the models and also add their allowed attributes in the controller params.
Here's how I did it:
I used the rails generate scaffold_controller
to get it done.
I simply ran the following commands:
rails generate scaffold_controller School name:string logo:json motto:text address:text
rails generate scaffold_controller Program name:string logo:json school:references
This generated the corresponding controllers for the models and also added their allowed attributes in the controller params, including the foreign key attributes.
create app/controllers/schools_controller.rb

WARNING:
The syntax list(groupby(...)) won't work the way that you intend. It seems to destroy the internal iterator objects, so using
for x in list(groupby(range(10))):
print(list(x[1]))
will produce:
[]
[]
[]
[]
[]
[]
[]
[]
[]

Instead, of list(groupby(...)), try [(k, list(g)) for k,g in groupby(...)], or if you use that syntax often,
def groupbylist(*args, **kwargs):
return [(k, list(g)) for k, g in groupby(*args, **kwargs)]
and get access to the groupby functionality while avoiding those pesky (for small data) iterators all together.
A common PyTorch convention is to save models using either a .pt or .pth file extension.
Save/Load Entire Model Save:
path = "username/directory/lstmmodelgpu.pth"
torch.save(trainer, path)
Load:
model = torch.load(PATH)
model.eval()
You can declare it yourself quite easily:
interface StringConstructor {
format: (formatString: string, ...replacement: any[]) => string;
}
String.format('','');
This is assuming that String.format is defined elsewhere. e.g. in Microsoft Ajax Toolkit : http://www.asp.net/ajaxlibrary/Reference.String-format-Function.ashx
Can you check value of i
by putting logger or println(). and check with closing db conn at the end. Rest your code looks fine and it should work.
The thing on the right of <-
is a formula
object. It is often used to denote a statistical model, where the thing on the left of the ~
is the response and the things on the right of the ~
are the explanatory variables. So in English you'd say something like "Species depends on Sepal Length, Sepal Width, Petal Length and Petal Width".
The myFormula <-
part of that line stores the formula in an object called myFormula
so you can use it in other parts of your R code.
Other common uses of formula objects in R
The lattice
package uses them to specify the variables to plot.
The ggplot2
package uses them to specify panels for plotting.
The dplyr
package uses them for non-standard evaulation.
Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.
Source: MSDN: Understanding Files and Filegroups
The recommended file name extension for secondary data files is .ndf
, but this is not enforced.
Here is how I would fix it, using a code snippet to give you a basic idea:

@FindBy(id = "iFrame1TextFieldTestProcessButtonID" ) public WebElement copyButton;
public IFrame1( RemoteWebDriver drv ) {

this.driver = drv;
this.driver.switchTo().defaultContent();
waitTimer(1, 1000);
this.driver.switchTo().frame("BodyFrame1");

I totally missed the export button at the bottom of each visualization. As for read only access...Shield from Elasticsearch might be worth exploring.
String search = "A";
for(String s : myList)
if(s.contains(search)) return true;
return false;
This will iterate over each string in the list, and check if it contains the string you're looking for. If it's only spaces you want to trap for, you can do this:
String search = "A";
for(String s : myList)
if(s.replaceAll(" ","").contains(search)) return true;
return false;
which will first replace spaces with empty strings before searching. Additionally, if you just want to trim the string first, you can do:
String search = "A";
for(String s : myList)
if(s.trim().contains(search)) return true;
return false;
Maybe you should try it with -quality 100 -size "1024x1024", because resize often gives results that are ugly to view.
lastrow = Sheet1.Range("A#").End(xlDown).Row
This is more easy to determine the row count.
Make sure you declare the right variable when it comes to larger rows.
By the way the '#' sign must be a number where you want to start the row count.
Just simple modification of @silgon answer:
while true; do
inotifywait -r -e modify,create,delete /directory
rsync -avz /directory /target
done
(@silgon version sometimes crashes on Ubuntu 16 if you run it in cron)
public void setHoursWorked(){
hoursWorked = hours;
}
You haven't defined hours
inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.
This works for me (tested OK!):
HTML:
<div class="mydiv">
<p>Item to be centered!</p>
</div>
CSS:
.mydiv {
height: 100%; /* Or other */
position: relative;
}
.mydiv p {
margin: 0;
position: absolute;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%); /* To compensate own width and height */
}
You can choose other values than 50%. For example, 25% to center at 25% of parent.
Assuming your data frame is named d
,
d[order(as.Date(d$V3, format="%d/%m/%Y")),]
Read my blog post, Sorting a data frame by the contents of a column, if that doesn't make sense.
There is a clean, one-line way of doing this in Pandas:
df['col_3'] = df.apply(lambda x: f(x.col_1, x.col_2), axis=1)
This allows f
to be a user-defined function with multiple input values, and uses (safe) column names rather than (unsafe) numeric indices to access the columns.
Example with data (based on original question):
import pandas as pd
df = pd.DataFrame({'ID':['1', '2', '3'], 'col_1': [0, 2, 3], 'col_2':[1, 4, 5]})
mylist = ['a', 'b', 'c', 'd', 'e', 'f']
def get_sublist(sta,end):
return mylist[sta:end+1]
df['col_3'] = df.apply(lambda x: get_sublist(x.col_1, x.col_2), axis=1)
Output of print(df)
:
ID col_1 col_2 col_3
0 1 0 1 [a, b]
1 2 2 4 [c, d, e]
2 3 3 5 [d, e, f]
If your column names contain spaces or share a name with an existing dataframe attribute, you can index with square brackets:
df['col_3'] = df.apply(lambda x: f(x['col 1'], x['col 2']), axis=1)
Note that the '=' is optional in C++11 universal initialization syntax, and it is generally considered better style to write :
char myarray[ARRAY_SIZE] {0}
You have writer.close();
in your code. So bash receives EOF on its stdin
and exits. Then you get Broken pipe
when trying to read from the stdout
of the defunct bash.
A good and simple example for nested try/except could be the following:
import numpy as np
def divide(x, y):
try:
out = x/y
except:
try:
out = np.inf * x / abs(x)
except:
out = np.nan
finally:
return out
Now try various combinations and you will get the correct result:
divide(15, 3)
# 5.0
divide(15, 0)
# inf
divide(-15, 0)
# -inf
divide(0, 0)
# nan
(Of course, we have NumPy, so we don't need to create this function.)
ng g c component-name
For specify custom location: ng g c specific-folder/component-name
here component-name
will be created inside specific-folder.
Similarl approach can be used for generating other components like directive
, pipe
, service
, class
, guard
, interface
, enum
, module
, etc.
You can also use the RestSharp library for example
var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");
client.Authenticator = new HttpBasicAuthenticator(userName, password);
var request = new RestRequest(Method.POST);
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
In my case (using IntelliJ) File
- Invalidate Caches / Restart...
did the trick.
From experience I'll just note that while it is the C++ way to put formerly-static functions into the anonymous namespace, older compilers can sometimes have problems with this. I currently work with a few compilers for our target platforms, and the more modern Linux compiler is fine with placing functions into the anonymous namespace.
But an older compiler running on Solaris, which we are wed to until an unspecified future release, will sometimes accept it, and other times flag it as an error. The error is not what worries me, it's what it might be doing when it accepts it. So until we go modern across the board, we are still using static (usually class-scoped) functions where we'd prefer the anonymous namespace.
I was facing the similar problem in OSx. My stacktrace was saying
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: setuptools>=11.3
Then I did the following
sudo pip install --upgrade setuptools
This solved the problem for me. Hope someone will find this useful.
If you are using Java, you can actually use commons-codec library
import org.apache.commons.codec.binary.Base64;
String stringToBeChecked = "...";
boolean isBase64 = Base64.isArrayByteBase64(stringToBeChecked.getBytes());
[UPDATE 1] Deprecation Notice Use instead
Base64.isBase64(value);
/**
* Tests a given byte array to see if it contains only valid characters within the Base64 alphabet. Currently the
* method treats whitespace as valid.
*
* @param arrayOctet
* byte array to test
* @return {@code true} if all bytes are valid characters in the Base64 alphabet or if the byte array is empty;
* {@code false}, otherwise
* @deprecated 1.5 Use {@link #isBase64(byte[])}, will be removed in 2.0.
*/
@Deprecated
public static boolean isArrayByteBase64(final byte[] arrayOctet) {
return isBase64(arrayOctet);
}
This technique is working for me:
$('#myInputFieldId').bind('input',function(){
alert("Hello");
});
Note that according to this JQuery doc, "on" is recommended rather than bind in newer versions.
Use the Below Code for that
UPDATE Table1 SET Column1 = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(Column1, CHAR(9), ''), CHAR(10), ''), CHAR(13), '')))`
Maybe I'm missing something, but wouldn't this suffice:
if (view instanceof B) {
// this view is an instance of B
}
I wrote this a while ago and really happy with it. Feel free to use it.
It takes an index
and total
and optionally title
or bar_length
. Once done, replaces the hour glass with a check-mark.
? Calculating: [¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦] 18.0% done
? Calculating: [¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦] 100.0% done
I included an example that can be run to test it.
import sys
import time
def print_percent_done(index, total, bar_len=50, title='Please wait'):
'''
index is expected to be 0 based index.
0 <= index < total
'''
percent_done = (index+1)/total*100
percent_done = round(percent_done, 1)
done = round(percent_done/(100/bar_len))
togo = bar_len-done
done_str = '¦'*int(done)
togo_str = '¦'*int(togo)
print(f'\t?{title}: [{done_str}{togo_str}] {percent_done}% done', end='\r')
if round(percent_done) == 100:
print('\t?')
r = 50
for i in range(r):
print_percent_done(i,r)
time.sleep(.02)
I also have a version with responsive progress bar depending on the terminal width using shutil.get_terminal_size()
if that is of interest.
Yes, there are a few of them.

In templates, you can separate filter arguments by colons.
{{ yourExpression | yourFilter: arg1:arg2:... }}
From Javascript, you call it as
$filter('yourFilter')(yourExpression, arg1, arg2, ...)
There is actually an example hidden in the orderBy filter docs.
Example:
Let's say you make a filter that can replace things with regular expressions:
myApp.filter("regexReplace", function() { // register new filter
return function(input, searchRegex, replaceRegex) { // filter arguments
return input.replace(RegExp(searchRegex), replaceRegex); // implementation
};
});
Invocation in a template to censor out all digits:
<p>{{ myText | regexReplace: '[0-9]':'X' }}</p>
I'd personally make use of the table.insert
function:
table.insert(a,"b");
This saves you from having to iterate over the whole table therefore saving valuable resources such as memory and time.
Looks like there're no single case when this error appears.
Happened to me when I didn't declare constructor in statefull component.
class MyComponent extends Component {
render() {
return <div>Test</div>;
}
}
instead of
class MyComponent extends Component {
constructor(props) {
super(props);
}
render() {
return <div>Test</div>;
}
}
In my case (Windows 10) the reason was that I dared to unzip the android sdk into non default folder. When I moved it to the default one c:/Users/[username]/AppData/Local/Android/Sdk and changed the paths in Android Studio and System Variables, it started to work.
There are two ways to do it..Say String==null or string.equals()..
public class IfElse {
public int ifElseTesting(String a){
//return null;
return (a== null)? 0: a.length();
}
}
public class ShortCutifElseTesting {
public static void main(String[] args) {
Scanner scanner=new Scanner(System.in);
System.out.println("enter the string please:");
String a=scanner.nextLine();
/*
if (a.equals(null)){
System.out.println("you are not correct");
}
else if(a.equals("bangladesh")){
System.out.println("you are right");
}
else
System.out.println("succesful tested");
*/
IfElse ie=new IfElse();
int result=ie.ifElseTesting(a);
System.out.println(result);
}
}
Check this example..Here is an another example of shortcut version of If Else..
You can do this using the ResourceManager
:
public bool info(string channel)
{
object o = Properties.Resources.ResourceManager.GetObject(channel);
if (o is Image)
{
channelPic.Image = o as Image;
return true;
}
return false;
}
If you have user specific credentials ( i.e each developer might have different username/password ) then I would recommend using the gradle-properties-plugin.
gradle.properties
gradle-local.properties
( this should be git ignored ).This is better than overriding using $USER_HOME/.gradle/gradle.properties
because different projects might have same property names.
Alternatively, you could invert the image using the bitwise_not
function of OpenCV:
imagem = cv2.bitwise_not(imagem)
I liked this example.
fscanf
- "On success, the function returns the number of items successfully read. This count can match the expected number of readings or be less -even zero- in the case of a matching failure.
In the case of an input failure before any data could be successfully read, EOF is returned."
So, instead of doing nothing with the return value like you are right now, you can check to see if it is == EOF
.
You should check for EOF when you call fscanf
, not check the array slot for EOF.

Your usage of now() is correct. However, you need to use one type of quotes around the entire query and another around the values.
You can modify your query to use double quotes at the beginning and end, and single quotes around $somename
:
$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='$somename'";
You can use =A4, in case A4 is having long formula
It's not possible in CSS at the moment, unless you want to select a child or sibling element (trivial and described in other answers here).
For all other cases you'll need JavaScript. jQuery and frameworks like Angular can tackle this problem with relative ease.
[Edit]
With the new CSS (4) selector :has(), you'll be able to target parent elements/classes, making a CSS-Only solution viable in the near future!
More convenient Swift 3 method:
let documentsUrl = FileManager.default.urls(for: .documentDirectory,
in: .userDomainMask).first!
there might be a problem at your web hosting company from where you are testing the secure communication for gateway, that they might not allow you to do that.
also there might be a username, password that must be provided before connecting to remote host.
or your IP might need to be in the list of approved IP for the remote server for communication to initiate.
Even though this is pretty old, I thought I would point out a cool feature I just found for listing tags with commits:

It will show the branches which end/start at a commit, and the tags for commits.
Here is a simple solution using the query-string
library.
const qs = require('query-string')
function addQuery(key, value) {
const q = qs.parse(location.search)
const url = qs.stringifyUrl(
{
url: location.pathname,
query: {
...q,
[key]: value,
},
},
{ skipEmptyString: true }
);
window.location.href = url
// if you are using Turbolinks
// add this: Turbolinks.visit(url)
}
// Usage
addQuery('page', 2)
If you are using react
without react-router
export function useAddQuery() {
const location = window.location;
const addQuery = useCallback(
(key, value) => {
const q = qs.parse(location.search);
const url = qs.stringifyUrl(
{
url: location.pathname,
query: {
...q,
[key]: value,
},
},
{ skipEmptyString: true }
);
window.location.href = url
},
[location]
);
return { addQuery };
}
// Usage
const { addQuery } = useAddQuery()
addQuery('page', 2)
If you are using react
with react-router
export function useAddQuery() {
const location = useLocation();
const history = useHistory();
const addQuery = useCallback(
(key, value) => {
let pathname = location.pathname;
let searchParams = new URLSearchParams(location.search);
searchParams.set(key, value);
history.push({
pathname: pathname,
search: searchParams.toString()
});
},
[location, history]
);
return { addQuery };
}
// Usage
const { addQuery } = useAddQuery()
addQuery('page', 2)
PS: qs
is the import from query-string
module.
To multiply, use mult
for signed multiplication and multu
for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0
that means that you assume the result will fit in 32 bits.
The 32 most significant bits will be held in the HI
special register (accessible by mfhi
instruction) and the 32 least significant bits will be held in the LO
special register (accessible by the mflo
instruction):
E.g.:
li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0
To divide, use div
for signed division and divu
for unsigned division. In this case, the HI
special register will hold the remainder and the LO
special register will hold the quotient of the division.
E.g.:
div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0
You need to open the file in append mode, by setting "a" or "ab" as the mode. See open().
When you open with "a" mode, the write position will always be at the end of the file (an append). You can open with "a+" to allow reading, seek backwards and read (but all writes will still be at the end of the file!).
Example:
>>> with open('test1','wb') as f:
f.write('test')
>>> with open('test1','ab') as f:
f.write('koko')
>>> with open('test1','rb') as f:
f.read()
'testkoko'
Note: Using 'a' is not the same as opening with 'w' and seeking to the end of the file - consider what might happen if another program opened the file and started writing between the seek and the write. On some operating systems, opening the file with 'a' guarantees that all your following writes will be appended atomically to the end of the file (even as the file grows by other writes).
A few more details about how the "a" mode operates (tested on Linux only). Even if you seek back, every write will append to the end of the file:
>>> f = open('test','a+') # Not using 'with' just to simplify the example REPL session
>>> f.write('hi')
>>> f.seek(0)
>>> f.read()
'hi'
>>> f.seek(0)
>>> f.write('bye') # Will still append despite the seek(0)!
>>> f.seek(0)
>>> f.read()
'hibye'
In fact, the fopen
manpage states:
Opening a file in append mode (a as the first character of mode) causes all subsequent write operations to this stream to occur at end-of-file, as if preceded the call:
fseek(stream, 0, SEEK_END);
with
):Example: (in a real program use with
to close the file - see the documentation)
>>> open("test","wb").write("test")
>>> open("test","a+b").write("koko")
>>> open("test","rb").read()
'testkoko'
string::c.str()
returns a string of type const char *
as seen here
A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str())
;
While the above may work, it is undefined behaviour, and unsafe.
Here's a nicer solution using templates:
char * my_argument = const_cast<char*> ( ...c_str() );
Though this might be too late to comment but here's the working code for problems such as yours.

If you are a Mac user and have keychain enabled, you to need to remove the authorization information that is stored in the keychain:
- Open up Keychain access
- Click "All items" under category in the left-hand column
- Search for git
- Delete all git entries.
Then you should change your username and email from the terminal using git config
:
$ git config --global user.name "Bob"
$ git config --global user.email "[email protected]"
Now if you try to push to the repository you will be asked for a username and password. Enter the login credentials you are trying to switch to. This problem normally pops up if you signed into GitHub on a browser using a different username and password or previously switched accounts on your terminal.
I use this function to indent my output (for example to print a tree structure). The indent
is the number of spaces before the string.
void print_with_indent(int indent, char * string)
{
printf("%*s%s", indent, "", string);
}
Those documents are outdated. I'm guessing the 1.6 in the URL is for Docker 1.6, not Compose 1.6. Check out the correct syntax here: https://docs.docker.com/compose/compose-file/#network_mode. You are looking for network_mode
when using the v2 YAML format.
I would recommend to use this since I have the same issue which got fixed.
$('input:text').focus(
function(){
$(this).val('');
});
Don't know it this is your problem but it was mine.

That means we need to not just copy the objects to a new array (or a target array), but also create copies of the objects.
...use map
to create a new array, and copy the objects as you go:
const newArray = sourceArray.map(obj => /*...create and return copy of `obj`...*/);
...where the copy operation is whatever way you prefer to copy objects, which varies tremendously project to project based on use case. That topic is covered in depth in the answers to this question. But for instance, if you only want to copy the objects but not any objects their properties refer to, you could use spread notation (ES2015+):
const newArray = sourceArray.map(obj => ({...obj}));
That does a shallow copy of each object (and of the array). Again, for deep copies, see the answers to the question linked above.
Here's an example using a naive form of deep copy that doesn't try to handle edge cases, see that linked question for edge cases:
function naiveDeepCopy(obj) {
const newObj = {};
for (const key of Object.getOwnPropertyNames(obj)) {
const value = obj[key];
if (value && typeof value === "object") {
newObj[key] = {...value};
} else {
newObj[key] = value;
}
}
return newObj;
}
const sourceArray = [

const newArray = sourceArray.map(naiveDeepCopy);
// Modify the first one and its sub-object
newArray[0].name = newArray[0].name.toLocaleUpperCase();
newArray[0].address.country = "United States of America";
console.log("Original:", sourceArray);
console.log("Copy:", newArray);

...and you want to append the contents of the source array to it, you can use push
and a loop:
for (const obj of sourceArray) {
destinationArray.push(copy(obj));
}
Sometimes people really want a "one liner," even if there's no particular reason for it. If you refer that, you could create a new array and then use spread notation to expand it into a single push
call:
destinationArray.push(...sourceArray.map(obj => copy(obj)));
Since this is the first google hit for the problem and I assume more people will search for this. There is a new option since Spring Boot '1.4.0'. It is now possible to define a custom RequestMappingHandlerMapping that allows to define a different path for classes annotated with @RestController
A different version with custom annotations that combines @RestController with @RequestMapping can be found at this blog post
@Configuration
public class WebConfig {
@Bean
public WebMvcRegistrationsAdapter webMvcRegistrationsHandlerMapping() {
return new WebMvcRegistrationsAdapter() {
@Override
public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
return new RequestMappingHandlerMapping() {
private final static String API_BASE_PATH = "api";
@Override
protected void registerHandlerMethod(Object handler, Method method, RequestMappingInfo mapping) {
Class<?> beanType = method.getDeclaringClass();
if (AnnotationUtils.findAnnotation(beanType, RestController.class) != null) {
PatternsRequestCondition apiPattern = new PatternsRequestCondition(API_BASE_PATH)
.combine(mapping.getPatternsCondition());
mapping = new RequestMappingInfo(mapping.getName(), apiPattern,
mapping.getMethodsCondition(), mapping.getParamsCondition(),
mapping.getHeadersCondition(), mapping.getConsumesCondition(),
mapping.getProducesCondition(), mapping.getCustomCondition());
}
super.registerHandlerMethod(handler, method, mapping);
}
};
}
};
}
}
I've found using cmd works well as an alternative, especially when you need to pipe the output from the called application (espeically when it doesn't have built in logging, unlike msbuild)
cmd /C "$msbuild $args" >> $outputfile
I've just managed to setup new TabLayout, so here are the quick steps to do this (????)?*:???
Add dependencies inside your build.gradle file:
dependencies {
compile 'com.android.support:design:23.1.1'
}
Add TabLayout inside your layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"/>
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Setup your Activity like this:
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
public class TabLayoutActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pull_to_refresh);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
tabLayout.setupWithViewPager(viewPager);
}
public class SectionPagerAdapter extends FragmentPagerAdapter {
public SectionPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new FirstTabFragment();
case 1:
default:
return new SecondTabFragment();
}
}
@Override
public int getCount() {
return 2;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "First Tab";
case 1:
default:
return "Second Tab";
}
}
}
}
if you want to use HEX instead of RGBA, just drag a new empty .swift and add below mentioned code:
import UIKit
extension UIColor {
convenience init(rgba: String) {
var red: CGFloat = 0.0
var green: CGFloat = 0.0
var blue: CGFloat = 0.0
var alpha: CGFloat = 1.0
if rgba.hasPrefix("#") {
let index = advance(rgba.startIndex, 1)
let hex = rgba.substringFromIndex(index)
let scanner = NSScanner(string: hex)
var hexValue: CUnsignedLongLong = 0
if scanner.scanHexLongLong(&hexValue) {
switch (count(hex)) {
case 3:
red = CGFloat((hexValue & 0xF00) >> 8) / 15.0
green = CGFloat((hexValue & 0x0F0) >> 4) / 15.0
blue = CGFloat(hexValue & 0x00F) / 15.0
case 4:
red = CGFloat((hexValue & 0xF000) >> 12) / 15.0
green = CGFloat((hexValue & 0x0F00) >> 8) / 15.0
blue = CGFloat((hexValue & 0x00F0) >> 4) / 15.0
alpha = CGFloat(hexValue & 0x000F) / 15.0
case 6:
red = CGFloat((hexValue & 0xFF0000) >> 16) / 255.0
green = CGFloat((hexValue & 0x00FF00) >> 8) / 255.0
blue = CGFloat(hexValue & 0x0000FF) / 255.0
case 8:
red = CGFloat((hexValue & 0xFF000000) >> 24) / 255.0
green = CGFloat((hexValue & 0x00FF0000) >> 16) / 255.0
blue = CGFloat((hexValue & 0x0000FF00) >> 8) / 255.0
alpha = CGFloat(hexValue & 0x000000FF) / 255.0
default:
print("Invalid RGB string, number of characters after '#' should be either 3, 4, 6 or 8")
}
} else {
println("Scan hex error")
}
} else {
print("Invalid RGB string, missing '#' as prefix")
}
self.init(red:red, green:green, blue:blue, alpha:alpha)
}
}
similarly, drag another empty .swift file and add below mentioned code:
class Colors {
let colorTop = UIColor(rgba: "##8968CD").CGColor
let colorBottom = UIColor(rgba: "#5D478B").CGColor
let gl: CAGradientLayer
init() {
gl = CAGradientLayer()
gl.colors = [ colorTop, colorBottom]
gl.locations = [ 0.0, 1.0]
}
}
after that in view controller, under class instantiate your 'Color' class like this:
let colors = Colors()
add a new function:
func refresh() {
view.backgroundColor = UIColor.clearColor()
var backgroundLayer = colors.gl
backgroundLayer.frame = view.frame
view.layer.insertSublayer(backgroundLayer, atIndex: 0)
}
state that function in viewDidLoad:
refresh()
you're done :)) using HEX is way too easy if compared to RGBA. :D
You should always try as much as possible to always put your statements in a try catch block ... it will always help in situations like this and will let you know whats wrong. Perhaps the table name or column name is wrong.
For those who find this on the internet. Check the Windows.csproj file if the compilation is there. There should be 2 entries
<Page Include="YourFile.xaml">
<SubType>Designer</SubType>
<Generator>MSBuild:Compile</Generator>
</Page>
<Compile Include="YourFile.xaml.cs">
<DependentUpon>YourFile.xaml</DependentUpon>
</Compile>
If you're developing in Flutter, there's a new experimental option as of 5/1/2018 that allows you to format code on save.
What about
30.seconds.ago
2.days.ago
Or something else you were shooting for?
Although the DATEADD
is probably the most transparrent way of doing this, it is worth noting
that simply getdate()-30
will also suffice.
Also, are you looking for 30 days from now, i.e. including hours, minutes, seconds, etc? Or 30 days from midnight today (e.g. 12/06/2010 00:00:00.000). In which case, you might consider:
SELECT *
FROM Results
WHERE convert(varchar(8), [Date], 112) >= convert(varchar(8), getdate(), 112)
In Swift 3.0 Apple removed 'NS' prefix and made everything simple. Below is the way to get hour, minute and second from 'Date' class (NSDate alternate)
let date = Date()
let calendar = Calendar.current
let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
print("hours = \(hour):\(minutes):\(seconds)")
Like these you can get era, year, month, date etc. by passing corresponding.
If this is C#, it won't work: enums are value types, and can't be null
.
The normal options are to add a None
member:
public enum Color
{
None,
Red,
Green,
Yellow
}
Color color = Color.None;
...or to use Nullable
:
Color? color = null;
Here is the algorithm I use to crypt with MD5.It returns your crypted output.
public class CryptWithMD5 {
private static MessageDigest md;
public static String cryptWithMD5(String pass){
try {
md = MessageDigest.getInstance("MD5");
byte[] passBytes = pass.getBytes();
md.reset();
byte[] digested = md.digest(passBytes);
StringBuffer sb = new StringBuffer();
for(int i=0;i<digested.length;i++){
sb.append(Integer.toHexString(0xff & digested[i]));
}
return sb.toString();
} catch (NoSuchAlgorithmException ex) {
Logger.getLogger(CryptWithMD5.class.getName()).log(Level.SEVERE, null, ex);
}
return null;
}
}
You cannot decrypt MD5, but you can compare outputs since if you put the same string in this method it will have the same crypted output.If you want to decrypt you need to use the SHA.You will never use decription for a users password.For that always use MD5.That exception is pretty redundant.It will never throw it.
The TextBlock doesn't support vertical text alignment.
I work around this by wrapping the text block with a Grid and setting HorizontalAlignment="Stretch" and VerticalAlignment="Center".
Like this:
<Grid>
<TextBlock
HorizontalAlignment="Stretch"
VerticalAlignment="Center"
Text="Your text" />
</Grid>
I ran into this recently and eventually found that this was caused by a network timeout from the endpoint we were hitting. Fortunately for us we were able to increase the timeout duration.
To verify this was our issue (and actually not an issue with net http), I made the same request with curl and confirmed that the request was being terminated.
Found the best way to do it for a server which does not support pkill
kill -9 $(ps ax | grep My_pattern| fgrep -v grep | awk '{ print $1 }')
You do not have to loop.
Step 1 :
Add this in htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]
</IfModule>
Step 2 :
Remove index.php in codeigniter config
$config['base_url'] = '';
$config['index_page'] = '';
Step 3 :
Allow overriding htaccess in Apache Configuration (Command)
sudo nano /etc/apache2/apache2.conf and edit the file & change to
AllowOverride All
for www folder
Step 4 :
Enabled apache mod rewrite (Command)
sudo a2enmod rewrite
Step 5 :
Restart Apache (Command)
sudo /etc/init.d/apache2 restart
Don't forget to include
import Image
In order to show it use this :
Image.open('pathToFile').show()
Conclusion,
to_char
works in its own way
So,
Always use this format YYYY-MM-DD for comparison instead of MM-DD-YY or DD-MM-YYYY or any other format
I found when using this method that the space between the td elements caused a gap to form in the border, but have no fear...
One way around this:
<tr>
<td>
Example of normal table data
</td>
<td class="end" colspan="/* total number of columns in entire table*/">
/* insert nothing in here */
</td>
</tr>
With the CSS:
td.end{
border:2px solid black;
}
Once you generated the file, and changed your password, you can run as below,
cntlm -H
Username will be the same. it will ask for password, give it, then copy the PassNTLMv2, edit the cntlm.ini, then just run the following
cntlm -v
Try:
if (isset($_FILES['uploaded_file']) &&
$_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK) {
$mail->AddAttachment($_FILES['uploaded_file']['tmp_name'],
$_FILES['uploaded_file']['name']);
}
Basic example can also be found here.
The function definition for AddAttachment
is:
public function AddAttachment($path,
$name = '',
$encoding = 'base64',
$type = 'application/octet-stream')
How about removing the onclick
attribute and adding an ID:
<input type="image" src="btn.png" alt="" id="img-clck" />
And your script:
$(document).ready(function(){
function codeAddress() {
var address = document.getElementById("formatedAddress").value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
}
});
}
$("#img-clck").click(codeAddress);
});
This way if you need to change the function name or whatever no need to touch the html.
Compilation settings that vim was compiled with, are part of the issue. vim --version
shows these.
In OSX, the default vim has -clipboard
But you need +clipboard
On osx you can and apparently generally should, use macvim. You can do brew cask install macvim
That one has +clipboard
.
Them you'll have two vims.
~$ ls -l /usr/bin/vim <--- default vim
-rwxr-xr-x 1 root wheel 1745984 15 Jul 2017 /usr/bin/vim
~$ ls -l /usr/local/bin/vim <-- macvim, installed recently via that mentioned brew line.
lrwxr-xr-x 1 apple admin 42 16 May 23:32 /usr/local/bin/vim -> /Applications/MacVim.app/Contents/bin/mvim
~$
running vim will run macvim 'cos /usr/local/bin
should be before /usr/bin
in the path, though you can check with which vim
.
running vim(to run macvim), is fine but you may want to map vi to macvim 'cos otherwise running vi stays at the default vim! You can rewrite or delete(with rm) and recreate the vi sym link, with ln. And to do that without an 'operation not permitted" error, you have to (temporarily) disable SIL. https://apple.stackexchange.com/questions/208478/how-do-i-disable-system-integrity-protection-sip-aka-rootless-on-macos-os-x .
macvim has +clipboard
as shown by vim --version
Here is a working ~/.vim/vimrc
with just the required lines.
:set mouse=a
:map <leader>c "+y
:map <leader>v "+p
The default leader key is backslash.
I read a suggestion that one should use the leader key.. (certainly control has many keys already in use, so the suggestion was to not use control. I don't know if that applies to command key too, but anyhow).
With that mentioned mapping, \c
will do "+y
which will copy from the register known as +, to the clipboard. And \v
will paste from the register known as +.
So that's a copy/paste that works between windows.
Another OS may require "*
rather than "+
Because testing port number is not a good practice according to me, my solution is:
define('HTTPS', isset($_SERVER['HTTPS']) && filter_var($_SERVER['HTTPS'], FILTER_VALIDATE_BOOLEAN));
The HTTPS
constant returns TRUE
if $_SERVER['HTTPS']
is set and equals to "1", "true", "on" or "yes".
Returns FALSE otherwise.
If you want everything in your post to be as $Variables you can use something like this:
foreach($_POST as $key => $value) {
eval("$" . $key . " = " . $value");
}
range()
: range(1, 10)
returns a list from 1 to 10 numbers & hold whole list in memory.xrange()
: Like range()
, but instead of returning a list, returns an object that generates the numbers in the range on demand. For looping, this is lightly faster than range()
and more memory efficient. xrange()
object like an iterator and generates the numbers on demand (Lazy Evaluation).In [1]: range(1,10)
Out[1]: [1, 2, 3, 4, 5, 6, 7, 8, 9]
In [2]: xrange(10)
Out[2]: xrange(10)
In [3]: print xrange.__doc__
Out[3]: xrange([start,] stop[, step]) -> xrange object
range()
does the same thing as xrange()
used to do in Python 3 and there is not term xrange()
exist in Python 3.
range()
can actually be faster in some scenario if you iterating over the same sequence multiple times. xrange()
has to reconstruct the integer object every time, but range()
will have real integer objects.
I had a similar situation, but the client config was using a basicHttpBinding. The issue turned out to be that the service was using SOAP 1.2 and you can't specify SOAP 1.2 in a basicHttpBinding. I modified the client config to use a customBinding instead and everything worked. Here are the details of my customBinding for reference. The service I was trying to consume was over HTTPS using UserNameOverTransport.
<customBinding>
<binding name="myBindingNameHere" sendTimeout="00:03:00">
<security authenticationMode="UserNameOverTransport" includeTimestamp="false">
<secureConversationBootstrap />
</security>
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Soap12" writeEncoding="utf-8">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>

</customBinding>
If you have two lists that have the predicted and actual values; as it appears you do, you can pass them to a function that will calculate TP, FP, TN, FN with something like this:
def perf_measure(y_actual, y_hat):
TP = 0
FP = 0
TN = 0
FN = 0
for i in range(len(y_hat)):
if y_actual[i]==y_hat[i]==1:
TP += 1
if y_hat[i]==1 and y_actual[i]!=y_hat[i]:
FP += 1
if y_actual[i]==y_hat[i]==0:
TN += 1
if y_hat[i]==0 and y_actual[i]!=y_hat[i]:
FN += 1
return(TP, FP, TN, FN)
From here I think you will be able to calculate rates of interest to you, and other performance measure like specificity and sensitivity.
Try this:
var d = new Date(),
minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(),
hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(),
ampm = d.getHours() >= 12 ? 'pm' : 'am',
months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;
