Returning pure array is slightly faster than returning an array of objects.
MyClass.class.getDeclaredConstructor(String.class).newInstance("HERESMYARG");
or
obj.getClass().getDeclaredConstructor(String.class).newInstance("HERESMYARG");
I suggest split (not saying that the other answers are invalid, this is just another way to do it):
def findreplace(char, string):
return ''.join(string.split(char))
Splitting by a character removes all the characters and turns it into a list. Then we join the list with the join function. You can see the ipython console test below
In[112]: findreplace('i', 'it is icy')
Out[112]: 't s cy'
And the speed...
In[114]: timeit("findreplace('it is icy','i')", "from __main__ import findreplace")
Out[114]: 0.9927914671134204
Not as fast as replace or translate, but ok.
In my opinion, using "if(value)" to judge a value whether is an empty value is not strict, because the result of "v?true:false" is false when the value of v is 0(0 is not an empty value). You can use this function:
const isEmptyValue = (value) => {
if (value === '' || value === null || value === undefined) {
return true
} else {
return false
}
}
I find myself using boost::lexical_cast
for this sort of thing all the time these days.
Example:
std::string input;
std::getline(std::cin,input);
int input_value;
try {
input_value=boost::lexical_cast<int>(input));
} catch(boost::bad_lexical_cast &) {
// Deal with bad input here
}
The pattern works just as well for your own classes too, provided they meet some simple requirements (streamability in the necessary direction, and default and copy constructors).
Construct a List<AppMeta>
from the excluded List and use the Except Linq operator.
var ex = excludedAppIds.Select(x => new AppMeta{Id = x}).ToList();
var result = ex.Except(unfilteredApps).ToList();
Sticking to the method you are using to insert it, use
list[:0] = ['foo']
http://docs.python.org/release/2.6.6/library/stdtypes.html#mutable-sequence-types
No, there is no better way.
Actually you have an error in your pattern. What you want is:
DecimalFormat df = new DecimalFormat("#.00");
Note the "00"
, meaning exactly two decimal places.
If you use "#.##"
(#
means "optional" digit), it will drop trailing zeroes - ie new DecimalFormat("#.##").format(3.0d);
prints just "3"
, not "3.00"
.
You will need to install a local mailserver in order to do this. If you want to send it to external e-mail addresses, it might end up in unwanted e-mails or it may not arrive at all.
A good mailserver which I use (I use it on Linux, but it's also available for Windows) is Axigen: http://www.axigen.com/mail-server/download/
You might need some experience with mailservers to install it, but once it works, you can do anything you want with it.

I think the classic answer is to create a more decoupled application, which has no knowledge of which implementation will be used during runtime.
For example, we're a central payment provider, working with many payment providers around the world. However, when a request is made, I have no idea which payment processor I'm going to call. I could program one class with a ton of switch cases, such as:
class PaymentProcessor{
private String type;
public PaymentProcessor(String type){
this.type = type;
}
public void authorize(){
if (type.equals(Consts.PAYPAL)){
// Do this;
}
else if(type.equals(Consts.OTHER_PROCESSOR)){
// Do that;
}
}
}
Now imagine that now you'll need to maintain all this code in a single class because it's not decoupled properly, you can imagine that for every new processor you'll support, you'll need to create a new if // switch case for every method, this only gets more complicated, however, by using Dependency Injection (or Inversion of Control - as it's sometimes called, meaning that whoever controls the running of the program is known only at runtime, and not complication), you could achieve something very neat and maintainable.
class PaypalProcessor implements PaymentProcessor{
public void authorize(){
// Do PayPal authorization
}
}
class OtherProcessor implements PaymentProcessor{
public void authorize(){
// Do other processor authorization
}
}
class PaymentFactory{
public static PaymentProcessor create(String type){
switch(type){
case Consts.PAYPAL;
return new PaypalProcessor();
case Consts.OTHER_PROCESSOR;
return new OtherProcessor();
}
}
}
interface PaymentProcessor{
void authorize();
}
** The code won't compile, I know :)
df = pd.read_csv('somefile.csv', low_memory=False)
This should solve the issue. I got exactly the same error, when reading 1.8M rows from a CSV.
You're close. You can strip the whitespace by using the replace
method like this:
$answer.replace(' ','')
There needs to be no space or characters between the second set of quotes in the replace method (replacing the whitespace with nothing).
My issue was simple: the Master page and Master.Designer.cs class had the correct Namespace, but the Master.cs class had the wrong namespace.

Why not just use the built-in Format() function?
Dim vTest As Variant
vTest = Empty ' or vTest = null or vTest = ""
If Format(vTest) = vbNullString Then
doSomethingWhenEmpty()
Else
doSomethingElse()
End If
Format() will catch empty variants as well as null ones and transforms them in strings. I use it for things like null/empty validations and to check if an item has been selected in a combobox.

I recently worked on a project to read the RFID tags. The project used the Devices from manufacturers like Zebra (we were using RFD8500 ) & TSL.
More devices are from Motorola & other vendors as well!
We have to use the native SDK api's provided by the manufacturer, how it works is by pairing the device by the Bluetooth of the phones and so the data transfer between both devices take place! The programming is based on subscribe pattern where the scan should be read by the device trigger(hardware trigger) or soft trigger (from the application).
The Tag read gives us the tagId & the RSSI which is the distance factor from the RFID tags!
This is the sample app:
We get all the device paired to our Android/iOS phones :
What you want to do is use the HTML5 attribute placeholder
which lets you set a default value for your input box:

I suggest the following to make sure everything is uninstalled:
sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev

In this sample, I created a JavaScript progress bar (with percentage display), you can control it and hide it with JavaScript.
In this sample, the progress bar advances every 100ms. You can see it in JSFiddle
var elapsedTime = 0;
var interval = setInterval(function() {
timer()
}, 100);
function progressbar(percent) {
document.getElementById("prgsbarcolor").style.width = percent + '%';
document.getElementById("prgsbartext").innerHTML = percent + '%';
}
function timer() {
if (elapsedTime > 100) {
document.getElementById("prgsbartext").style.color = "#FFF";
document.getElementById("prgsbartext").innerHTML = "Completed.";
if (elapsedTime >= 107) {
clearInterval(interval);
history.go(-1);
}
} else {
progressbar(elapsedTime);
}
elapsedTime++;
}
I know this might be an old question but I have a simple solution for low-level beginners in JavaScript.
As a beginner, I could only understand some of the solutions to this question so I used two nested FOR loops to check each character against every other character in the string, incrementing a count variable for each character found that equals that character.
I created a new blank object where each property key is a character and the value is how many times each character appeared in the string(count).
Example function:-
function countAllCharacters(str) {
var obj = {};
if(str.length!==0){
for(i=0;i<str.length;i++){
var count = 0;
for(j=0;j<str.length;j++){
if(str[i] === str[j]){
count++;
}
}
if(!obj.hasOwnProperty(str[i])){
obj[str[i]] = count;
}
}
}
return obj;
}

I ran into this problem a lot when attempting to use SVG with react.
I ended up using quite a dirty fix, but it's useful to know this option existed. Below I allow the use of the vector-effect
attribute on SVG elements.
import SVGDOMPropertyConfig from 'react/lib/SVGDOMPropertyConfig.js';
import DOMProperty from 'react/lib/DOMProperty.js';
SVGDOMPropertyConfig.Properties.vectorEffect = DOMProperty.injection.MUST_USE_ATTRIBUTE;
SVGDOMPropertyConfig.DOMAttributeNames.vectorEffect = 'vector-effect';
As long as this is included/imported before you start using react, it should work.

Use -a
(for and) and -o
(for or) operations.
tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html
Update
Actually you could still use &&
and ||
with the -eq
operation. So your script would be like this:
my_error_flag=1
my_error_flag_o=1
if [ $my_error_flag -eq 1 ] || [ $my_error_flag_o -eq 2 ] || ([ $my_error_flag -eq 1 ] && [ $my_error_flag_o -eq 2 ]); then
echo "$my_error_flag"
else
echo "no flag"
fi
Although in your case you can discard the last two expressions and just stick with one or operation like this:
my_error_flag=1
my_error_flag_o=1
if [ $my_error_flag -eq 1 ] || [ $my_error_flag_o -eq 2 ]; then
echo "$my_error_flag"
else
echo "no flag"
fi
If you are using Auto Layout then you can do it on the Story board.
Add a height constraint to the text field, then change the height constraint constant to any desired value. Steps are shown below:
Step 1: Create a height constraint for the text field
Step 2: Select Height Constraint
Step 3: Change Height Constraint's constant value
If we need only one column to be numeric
yyz$b <- as.numeric(as.character(yyz$b))
But, if all the columns needs to changed to numeric
, use lapply
to loop over the columns and convert to numeric
by first converting it to character
class as the columns were factor
.
yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))
Both the columns in the OP's post are factor
because of the string "n/a"
. This could be easily avoided while reading the file using na.strings = "n/a"
in the read.table/read.csv
or if we are using data.frame
, we can have character
columns with stringsAsFactors=FALSE
(the default is stringsAsFactors=TRUE
)
Regarding the usage of apply
, it converts the dataset to matrix
and matrix
can hold only a single class. To check the class
, we need
lapply(yyz, class)
Or
sapply(yyz, class)
Or check
str(yyz)
There are several design patterns that can be called wrapper classes.

The key is in the quotes around the colon and &, i.e. rows(variable & ":" & variable).select
Adapt this:
Rows(x & ":" & y).select
where x and y are your variables.
Some other examples that may help you understand
Rows(x & ":" & x).select
Or
Rows((x+1) & ":" (x*3)).select
Or
Rows((x+2) & ":" & (y-3)).select

You can create an item in your custom SharePoint list doing something like this:
using (SPSite site = new SPSite("http://sharepoint"))

SPListItem listItem = list.AddItem();
listItem["Title"] = "The Title";
listItem["CustomColumn"] = "I am custom";
listItem.Update();

If you're using display:table-row
etc., then you need proper markup, which includes a containing table. Without it your original question basically provides the equivalent bad markup of:
<tr style="width:100%">
<td>Type</td>
<td style="float:right">Name</td>
</tr>
Where's the table in the above? You can't just have a row out of nowhere (tr must be contained in either table
, thead
, tbody
, etc.)
Instead, add an outer element with display:table
, put the 100% width on the containing element. The two inside cells will automatically go 50/50 and align the text right on the second cell. Forget floats
with table elements. It'll cause so many headaches.
markup:
<div class="view-table">
<div class="view-row">
<div class="view-type">Type</div>
<div class="view-name">Name</div>
</div>
</div>
CSS:
.view-table
{
display:table;
width:100%;
}
.view-row,
{
display:table-row;
}
.view-row > div
{
display: table-cell;
}
.view-name
{
text-align:right;
}
To add a row:
DataRow row = dt.NewRow();
row["Name"] = "Ravi";
row["Marks"] = 500;
dt.Rows.Add(row);
To see the structure:
Table.Columns
Apart from the information given by David M. Lloyd one could add that the mechanism that allows this is called target typing.
The idea is that the type the compiler assigns to a lambda expressions or a method references does not depend only on the expression itself, but also on where it is used.
The target of an expression is the variable to which its result is assigned or the parameter to which its result is passed.
Lambda expressions and method references are assigned a type which matches the type of their target, if such a type can be found.
See the Type Inference section in the Java Tutorial for more information.
you can just do $scope.todo = Todo.get({ id: 123 })
. .get()
and .query()
on a Resource return an object immediately and fill it with the result of the promise later (to update your template). It's not a typical promise which is why you need to either use a callback or the $promise property if you have some special code you want executed after the call. But there is no need to assign it to your scope in a callback if you are only using it in the template.
$('#foo option:selected').data('id');
Wherever you have Text
component in your page just you need to set style of the Text
component.
<Text style={{ textAlign: 'center' }}> Text here </Text>
you don't need to add any other styling property, this is spectacular magic it will set you text in center of the your UI.
Found a solution. This problem happens, when you import a project.
The solution is simple
Now you should see the web app libraries showing your jars added.
You can set the ReadOnly property to true.
Quoth the link:
When this property is set to true, the contents of the control cannot be changed by the user at runtime. With this property set to true, you can still set the value of the Text property in code. You can use this feature instead of disabling the control with the Enabled property to allow the contents to be copied and ToolTips to be shown.
If you'll go through these steps:
brew install jmeter
and hit Enterjmeter
and hit Enter againYou won't have to solve any kind of issue. Don't thank
The FAQ is not available anymore.
From the documentation of shrinkwrap
:
If you wish to lock down the specific bytes included in a package, for example to have 100% confidence in being able to reproduce a deployment or build, then you ought to check your dependencies into source control, or pursue some other mechanism that can verify contents rather than versions.
Shannon and Steven mentioned this before but I think, it should be part of the accepted answer.
The source listed for the below recommendation has been updated. They are no longer recommending the node_modules
folder be committed.
Usually, no. Allow npm to resolve dependencies for your packages.
For packages you deploy, such as websites and apps, you should use npm shrinkwrap to lock down your full dependency tree:
For reference, npm FAQ answers your question clearly:
Check node_modules into git for things you deploy, such as websites and apps. Do not check node_modules into git for libraries and modules intended to be reused. Use npm to manage dependencies in your dev environment, but not in your deployment scripts.
and for some good rationale for this, read Mikeal Rogers' post on this.

sqlcmd works, System.Data.SqlClient not working - Server not found in Kerberos database. You should add RestrictedKrbHost SPN
5.1.2 SPNs with Serviceclass Equal to "RestrictedKrbHost"
Supporting the "RestrictedKrbHost" service class allows client applications to use Kerberos authentication when they do not have the identity of the service but have the server name. This does not provide client-to-service mutual authentication, but rather client-to-server computer authentication. Services of different privilege levels have the same session key and could decrypt each other's data if the underlying service does not ensure that data cannot be accessed by higher services.
Click on the cell you want to copy. In the formula bar, highlight the formula.
Press Ctrl C
.
Press escape (to take you out of actively editing that formula).
Choose new cell. Ctrl V.
To preserve key order, instead of hash(str(dictionary))
or hash(json.dumps(dictionary))
I would prefer quick-and-dirty solution:
from pprint import pformat
h = hash(pformat(dictionary))
It will work even for types like DateTime
and more that are not JSON serializable.
Or you can try using git revert http://www.kernel.org/pub/software/scm/git/docs/git-revert.html. I think something like git revert HEAD~1 -m 1
will revert your last commit (if it's still the last commit).
I guess this may be an issue about limited contexts, e.g. WYIWYG editors on a web system used by not-programmers users, that limits the possibilities of follow the standards. Sometimes (like TinyMCE), it's a lib that puts your content/code inside a textarea
tag, that is rendered by the editor as a big div
tag. And sometimes, it may be an old version of these editors.
I'm supposing that:
stylesheets
. Actually, it would be impractical for the admins (or webdevs), considering the number of requests in that sense that they would have.In some cases, without use style
rules, it may be a very poor design experience. So, yes, these users need customization. Okay, but what would be the solutions, in this scenario? Considering the different ways to insert CSS in a html
page, I suppose these solutions:
Ask to your system adm for including some CSS rules at the system's stylesheets
. This will be an external or internal CSS solution. As already said, it might be not possible.
<link>
on <body>
Use external style sheet on the body
tag, i.e., use of the link
tag inside the area you have access (that will be, on the site, inside the body
tag and not in the head
tag). Some sources says this is okay, but "not a good practice", like MDN:
A
<link>
element can occur either in the<head>
or<body>
element, depending on whether it has a link type that is body-ok. For example, thestylesheet
link type is body-ok, and therefore<link rel="stylesheet">
is permitted in the body. However, this isn't a good practice to follow; it makes more sense to separate your<link>
elements from your body content, putting them in the<head>
.
Some others, restrict it to the <head>
section, like w3schools:
Note: This element goes only in the head section, but it can appear any number of times.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file foo.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<link href="bar.css" type="text/css" rel="stylesheet">
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
</body>
</html>
And then a CSS file, at the same directory, called bar.css
:
.test1 {
color: green;
};
Well, this will just looks possible if you have how upload an CSS file somewhere at the institution system. Maybe this would be the case.
<style>
on <body>
Use internet style sheet on the body
tag, i.e., use of the style
tag inside the area you have access (that will be, on the site, inside the body
tag and not in the head
tag). This is what Charles Salvia's and Sz's answers here are about. Choosing this option, consider their concerns.
Alert
These ones are related to modifying the <head>
element of the page. Maybe this will not be allowed by the institution's system administrators. So, it's recommended to ask them permission first.
Okay, supposing permission granted, the strategy is access the <head>
. How? JavaScript methods.
<link>
on <head>
This is another version of the 2nd option. Use external style sheet on the <head>
tag, i.e., use of the <link>
element outside the area you have access (that will be, on the site, not inside the body
tag and yes inside the head
tag). This solution complies with the recommendations of MDN and w3schools, as cited above, on 2nd option solution. A new Link
object will be created.
To solve the matter through JS, there are many ways but at the following codelines I demonstrate one simple.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file f.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
<script>
// JS code here
</script>
</body>
</html>
Inside the script
tag:
var newLink = document.createElement("link");
newLink.href = "bar.css";
newLink.rel = "stylesheet";
newLink.type = "text/css";
document.getElementsByTagName("head")[0].appendChild(newLink);
And then at the CSS file, at the same directory, called bar.css
(as at the 2nd option):
.test1 {
color: green;
};
As I already said: this will just looks possible if you have how upload an CSS file somewhere at the institution system.
<style>
on <head>
Use new internal style sheet on the <head>
tag, i.e., use of a new <style>
element outside the area you have access (that will be, on the site, not inside the body
tag and yes inside the head
tag). A new Style
object will be created.
This is solved through JS. One simple way is demonstrated following.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file foobar.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
<script>
// JS code here
</script>
</body>
</html>
Inside the script
tag:
var newStyle = document.createElement("style");
newStyle.innerHTML =
"h1.test1 {"+
"color: green;"+
"}";
document.getElementsByTagName("head")[0].appendChild(newStyle);
<style>
on <head>
Use an existing internal style sheet on the <head>
tag, i.e., use of a <style>
element outside the area you have access (that will be, on the site, not inside the body
tag and yes inside the head
tag), if some exists. A new Style
object will be created or a CSSStyleSheet
object will be used (in the code of the solution adopted here).
This is at some point of view risky.
First, because it may not exists some <style>
object. Depending of the way you implement this solution, you may get undefined
return (the system may use external style sheet).
Second, because you will be editing the system design author's work (authorship issues).
Third, because it may not be allowed at your institution's IT politics of safety.
So, do ask permission to do this (as at in other JS solutions).
Supposing, again, permission was granted:
You will need to consider some restrictions of the method available to this way: insertRule()
. The solution proposed uses the default scenario, and a operation at the first stylesheet
, if some exists.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file foo_bar.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
<script>
// JS code here
</script>
</body>
</html>
Inside the script
tag:
function demoLoop(){ // remove this line
var elmnt = document.getElementsByTagName("style");
if (elmnt.length === 0) {
// there isn't style objects, so it's more interesting create one
var newStyle = document.createElement("style");
newStyle.innerHTML =
"h1.test1 {" +
"color: green;" +
"}";
document.getElementsByTagName("head")[0].appendChild(newStyle);
} else {
// Using CSSStyleSheet interface
var firstCSS = document.styleSheets[0];
firstCSS.insertRule("h1.test2{color:blue;}"); // at this way (without index specified), will be like an Array unshift() method
}
} // remove this too
demoLoop(); // remove this too
demoLoop(); // remove this too
Another approach to this solution it's using CSSStyleDeclaration
object (docs at w3schools and MDN). But it may not be interesting, considering the risk to override existing rules on the system's CSS.
Use inline CSS. This solve the problem, although depending of the page size (in code lines), the maintenance (by the author itself or other assigned person) of code can be very difficult.
But depending of the context of your role at the institution, or its web system security policies, this might be the unique available solution to you.
Create a file _foobar.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 style="color: green;">Hello</h1>
<h1 style="color: blue;">World</h1>
</body>
</html>
How is a browser supposed to render css which is non contiguous?
- Is it supposed to generate some data structure using all the css styles on a page and use that for rendering?
- Or does it render using style information in the order it sees?

For a more accurate answer, I suggest Google these articles:
It's a SQL Compact database. You need to define what you mean by "Open". You can open it via code with the SqlCeConnection so you can write your own tool/app to access it.
Visual Studio can also open the files directly if was created with the right version of SQL Compact.
There are also some third-party tools for manipulating them.
If you are not interested in the host name (for example www.beta.example.com
) but in the domain name (for example example.com
), this works for valid host names:
function getDomainName(hostName)
{
return hostName.substring(hostName.lastIndexOf(".", hostName.lastIndexOf(".") - 1) + 1);
}
The body

If you are using the ‘static’ keyword without the ‘final’ keyword, this should be a signal to carefully consider your design. Even the presence of a ‘final’ is not a free pass, since a mutable static final object can be just as dangerous.
I would estimate somewhere around 85% of the time I see a ‘static’ without a ‘final’, it is WRONG. Often, I will find strange workarounds to mask or hide these problems.
Please don’t create static mutables. Especially Collections. In general, Collections should be initialized when their containing object is initialized and should be designed so that they are reset or forgotten about when their containing object is forgotten.
Using statics can create very subtle bugs which will cause sustaining engineers days of pain. I know, because I’ve both created and hunted these bugs.
If you would like more details, please read on…
Why Not Use Statics?
There are many issues with statics, including writing and executing tests, as well as subtle bugs that are not immediately obvious.
Code that relies on static objects can’t be easily unit tested, and statics can’t be easily mocked (usually).
If you use statics, it is not possible to swap the implementation of the class out in order to test higher level components. For example, imagine a static CustomerDAO that returns Customer objects it loads from the database. Now I have a class CustomerFilter, that needs to access some Customer objects. If CustomerDAO is static, I can’t write a test for CustomerFilter without first initializing my database and populating useful information.
And database population and initialization takes a long time. And in my experience, your DB initialization framework will change over time, meaning data will morph, and tests may break. IE, imagine Customer 1 used to be a VIP, but the DB initialization framework changed, and now Customer 1 is no longer VIP, but your test was hard-coded to load Customer 1…
A better approach is to instantiate a CustomerDAO, and pass it into the CustomerFilter when it is constructed. (An even better approach would be to use Spring or another Inversion of Control framework.
Once you do this, you can quickly mock or stub out an alternate DAO in your CustomerFilterTest, allowing you to have more control over the test,
Without the static DAO, the test will be faster (no db initialization) and more reliable (because it won’t fail when the db initialization code changes). For example, in this case ensuring Customer 1 is and always will be a VIP, as far as the test is concerned.
Executing Tests
Statics cause a real problem when running suites of unit tests together (for example, with your Continuous Integration server). Imagine a static map of network Socket objects that remains open from one test to another. The first test might open a Socket on port 8080, but you forgot to clear out the Map when the test gets torn down. Now when a second test launches, it is likely to crash when it tries to create a new Socket for port 8080, since the port is still occupied. Imagine also that Socket references in your static Collection are not removed, and (with the exception of WeakHashMap) are never eligible to be garbage collected, causing a memory leak.
This is an over-generalized example, but in large systems, this problem happens ALL THE TIME. People don’t think of unit tests starting and stopping their software repeatedly in the same JVM, but it is a good test of your software design, and if you have aspirations towards high availability, it is something you need to be aware of.
These problems often arise with framework objects, for example, your DB access, caching, messaging, and logging layers. If you are using Java EE or some best of breed frameworks, they probably manage a lot of this for you, but if like me you are dealing with a legacy system, you might have a lot of custom frameworks to access these layers.
If the system configuration that applies to these framework components changes between unit tests, and the unit test framework doesn’t tear down and rebuild the components, these changes can’t take effect, and when a test relies on those changes, they will fail.
Even non-framework components are subject to this problem. Imagine a static map called OpenOrders. You write one test that creates a few open orders, and checks to make sure they are all in the right state, then the test ends. Another developer writes a second test which puts the orders it needs into the OpenOrders map, then asserts the number of orders is accurate. Run individually, these tests would both pass, but when run together in a suite, they will fail.
Worse, failure might be based on the order in which the tests were run.
In this case, by avoiding statics, you avoid the risk of persisting data across test instances, ensuring better test reliability.
Subtle Bugs
If you work in high availability environment, or anywhere that threads might be started and stopped, the same concern mentioned above with unit test suites can apply when your code is running on production as well.
When dealing with threads, rather than using a static object to store data, it is better to use an object initialized during the thread’s startup phase. This way, each time the thread is started, a new instance of the object (with a potentially new configuration) is created, and you avoid data from one instance of the thread bleeding through to the next instance.
When a thread dies, a static object doesn’t get reset or garbage collected. Imagine you have a thread called “EmailCustomers”, and when it starts it populates a static String collection with a list of email addresses, then begins emailing each of the addresses. Lets say the thread is interrupted or canceled somehow, so your high availability framework restarts the thread. Then when the thread starts up, it reloads the list of customers. But because the collection is static, it might retain the list of email addresses from the previous collection. Now some customers might get duplicate emails.
An Aside: Static Final
The use of “static final” is effectively the Java equivalent of a C #define, although there are technical implementation differences. A C/C++ #define is swapped out of the code by the pre-processor, before compilation. A Java “static final” will end up memory resident on the stack. In that way, it is more similar to a “static const” variable in C++ than it is to a #define.
Summary
I hope this helps explain a few basic reasons why statics are problematic up. If you are using a modern Java framework like Java EE or Spring, etc, you may not encounter many of these situations, but if you are working with a large body of legacy code, they can become much more frequent.
Agile and Scrum are terms used in project management. The Agile methodology employs incremental and iterative work beats that are also called sprints. Scrum, on the other hand is the type of agile approach that is used in software development.
Agile is the practice and Scrum is the process to following this practice same as eXtreme Programming (XP) and Kanban are the alternative process to following Agile development practice.

i guess your could use the --name-only
flag. something like:
git log 73167b96 --pretty="format:" --name-only
i personally use git show
for viewing files changed in a commit
git show --pretty="format:" --name-only 73167b96
(73167b96 could be any commit/tag name)

a combination of answers gave me a very fast running time. using the shift method to create new column of next row values, then using the row_iterator function as @alisdt did, but here i changed it from iterrows to itertuples which is 100 times faster.
my script is for iterating dataframe of duplications in different length and add one second for each duplication so they all be unique.
# create new column with shifted values from the departure time column
df['next_column_value'] = df['column_value'].shift(1)
# create row iterator that can 'save' the next row without running for loop
row_iterator = df.itertuples()
# jump to the next row using the row iterator
last = next(row_iterator)
# because pandas does not support items alteration i need to save it as an object
t = last[your_column_num]
# run and update the time duplications with one more second each
for row in row_iterator:
if row.column_value == row.next_column_value:
t = t + add_sec
df_result.at[row.Index, 'column_name'] = t
else:
# here i resetting the 'last' and 't' values
last = row
t = last[your_column_num]
Hope it will help.
If you want something like global constants; a quick an dirty way is to put the constant declarations into the pch
file.
I face the same issues recently, to solve this problem(simple and fast algorithm to compare two images) once and for all, I contribute an img_hash module to opencv_contrib, you can find the details from this link.
img_hash module provide six image hash algorithms, quite easy to use.
Codes example
#include <opencv2/core.hpp>
#include <opencv2/core/ocl.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/img_hash.hpp>
#include <opencv2/imgproc.hpp>
#include <iostream>
void compute(cv::Ptr<cv::img_hash::ImgHashBase> algo)
{
auto input = cv::imread("lena.png");
cv::Mat similar_img;
//detect similiar image after blur attack
cv::GaussianBlur(input, similar_img, {7,7}, 2, 2);
cv::imwrite("lena_blur.png", similar_img);
cv::Mat hash_input, hash_similar;
algo->compute(input, hash_input);
algo->compute(similar_img, hash_similar);
std::cout<<"gaussian blur attack : "<<
algo->compare(hash_input, hash_similar)<<std::endl;
//detect similar image after shift attack
similar_img.setTo(0);
input(cv::Rect(0,10, input.cols,input.rows-10)).
copyTo(similar_img(cv::Rect(0,0,input.cols,input.rows-10)));
cv::imwrite("lena_shift.png", similar_img);
algo->compute(similar_img, hash_similar);
std::cout<<"shift attack : "<<
algo->compare(hash_input, hash_similar)<<std::endl;
//detect similar image after resize
cv::resize(input, similar_img, {120, 40});
cv::imwrite("lena_resize.png", similar_img);
algo->compute(similar_img, hash_similar);
std::cout<<"resize attack : "<<
algo->compare(hash_input, hash_similar)<<std::endl;
}
int main()
{
using namespace cv::img_hash;
//disable opencl acceleration may(or may not) boost up speed of img_hash
cv::ocl::setUseOpenCL(false);
//if the value after compare <= 8, that means the images
//very similar to each other
compute(ColorMomentHash::create());
//there are other algorithms you can try out
//every algorithms have their pros and cons
compute(AverageHash::create());
compute(PHash::create());
compute(MarrHildrethHash::create());
compute(RadialVarianceHash::create());
//BlockMeanHash support mode 0 and mode 1, they associate to
//mode 1 and mode 2 of PHash library
compute(BlockMeanHash::create(0));
compute(BlockMeanHash::create(1));
}
In this case, ColorMomentHash give us best result
Pros and cons of each algorithm
The performance of img_hash is good too
Speed comparison with PHash library(100 images from ukbench)
If you want to know the recommend thresholds for these algorithms, please check this post(http://qtandopencv.blogspot.my/2016/06/introduction-to-image-hash-module-of.html). If you are interesting about how do I measure the performance of img_hash modules(include speed and different attacks), please check this link(http://qtandopencv.blogspot.my/2016/06/speed-up-image-hashing-of-opencvimghash.html).
If you can use inline styling, you can set the left and right padding on each td
.. Or you use an extra td
between columns and set a number of non-breaking spaces as @rene kindly suggested.
Both are pretty ugly ;p css ftw

Unfortunately, (for practical and security reasons I guess), if you want to add/copy local content, it must be located under the same root path than the Dockerfile
.
From the documentation:
The <src> path must be inside the context of the build; you cannot ADD ../something/something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon.
EDIT: There's now an option (-f
) to set the path of your Dockerfile ; it can be used to achieve what you want, see @Boedy 's response.
Since youre using JSON, I would Base64 Encode it before sending it across the wire.
If the files are large, try to look at BSON, or some other format that is better with binary transfers.
You could also zip the files, if they compress well, before base64 encoding them.
Because I know it's possible in while conditions, but I'm not sure if I'm doing it wrong for the if-statement or if it's just not possible.
HINT: what type while and if condition should be ??
If it can be done with while, it can be done with if statement as weel, as both of them expect a boolean condition.
I was having this issue when viewing my website on a phone. While I was trying to close the overlay, I was pretty much clicking on anything under the overlay. A solution that I found working for myself is to just add a

Make one or both of the terms a floating point number, like so:

Alternatively, turn on the feature that will be default in Python 3.0, 'true division', that does what you want. At the top of your module or script, do:

There is a simple trick if it is a BOOL parameter.
Pass nil for NO and self for YES. nil is cast to the BOOL value of NO. self is cast to the BOOL value of YES.
This approach breaks down if it is anything other than a BOOL parameter.
Assuming self is a UIView.
//nil will be cast to NO when the selector is performed
[self performSelector:@selector(setHidden:) withObject:nil afterDelay:5.0];
//self will be cast to YES when the selector is performed
[self performSelector:@selector(setHidden:) withObject:self afterDelay:10.0];

Unix will only run commands if they are available on the system path, as you can view by the $PATH variable
echo $PATH
Executables located in directories that are not on the path cannot be run unless you specify their full location. So in your case, assuming the executable is in the current directory you are working with, then you can execute it as such
./my-exec
Where my-exec
is the name of your program.

Most modern linkers include a verbose option that prints out to varying degrees;
For gcc and clang; you would typically add -v -Wl,--verbose
or -v -Wl,-v
to the command line. More details can be found here;
For MSVC, /VERBOSE
(in particular /VERBOSE:LIB
) is added to the link command line.
/VERBOSE
linker option.Using dictionaries should be right way to keep the variables and associated values, and you may use this:
dict_ = {}
for i in range(9):
dict_['string%s' % i] = 'Hello'
But if you want to add the variables to the local variables you can use:
for i in range(9):
exec('string%s = Hello' % i)
And for example if you want to assign values 0 to 8 to them, you may use:
for i in range(9):
exec('string%s = %s' % (i,i))
int segundo = 0;
DateTime dt = new DateTime();
private void timer1_Tick(object sender, EventArgs e){
segundo++;
label1.Text = dt.AddSeconds(segundo).ToString("HH:mm:ss");
}
The Python approach to "main" is almost unique to the language(*).
The semantics are a bit subtle. The __name__
identifier is bound to the name of any module as it's being imported. However, when a file is being executed then __name__
is set to "__main__"
(the literal string: __main__
).
This is almost always used to separate the portion of code which should be executed from the portions of code which define functionality. So Python code often contains a line like:
#!/usr/bin/env python
from __future__ import print_function
import this, that, other, stuff
class SomeObject(object):
pass
def some_function(*args,**kwargs):
pass
if __name__ == '__main__':
print("This only executes when %s is executed rather than imported" % __file__)
Using this convention one can have a file define classes and functions for use in other programs, and also include code to evaluate only when the file is called as a standalone script.
It's important to understand that all of the code above the if __name__
line is being executed, evaluated, in both cases. It's evaluated by the interpreter when the file is imported or when it's executed. If you put a print
statement before the if __name__
line then it will print output every time any other code attempts to import that as a module. (Of course, this would be anti-social. Don't do that).
I, personally, like these semantics. It encourages programmers to separate functionality (definitions) from function (execution) and encourages re-use.
Ideally almost every Python module can do something useful if called from the command line. In many cases this is used for managing unit tests. If a particular file defines functionality which is only useful in the context of other components of a system then one can still use __name__ == "__main__"
to isolate a block of code which calls a suite of unit tests that apply to this module.
(If you're not going to have any such functionality nor unit tests than it's best to ensure that the file mode is NOT executable).
Summary: if __name__ == '__main__':
has two primary use cases:
It's fairly common to def main(*args)
and have if __name__ == '__main__':
simply call main(*sys.argv[1:])
if you want to define main in a manner that's similar to some other programming languages. If your .py file is primarily intended to be used as a module in other code then you might def test_module()
and calling test_module()
in your if __name__ == '__main__:'
suite.
if __file__ == $0
).Since there's no answer using regular array find
:
var one = {id: 1, name: 'one'};
var two = {id: 2, name:'two'}
var arr = [one, two]
var found = arr.find((a) => a.id === 2)
found === two // true
arr.indexOf(found) // 1
This is how it worked for me (from above answers it was showing both default title and my custom view also).
ActionBar.LayoutParams layout = new ActionBar.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
// actionBar.setCustomView(view); //last view item must set to android:layout_alignParentRight="true" if few views are there
actionBar.setCustomView(view, layout); // layout param width=fill/match parent
actionBar.setDisplayShowCustomEnabled(true);//must other wise its not showing custom view.
What I noticed is that both setCustomView(view)
and setCustomView(view,params)
the view width=match/fill parent. setDisplayShowCustomEnabled (boolean showCustom)
Use setInterval
:
$(function(){
setInterval(oneSecondFunction, 1000);
});
function oneSecondFunction() {
// stuff you want to do every second
}
Here's an article on the difference between setTimeout
and setInterval
. Both will provide the functionality you need, they just require different implementations.
Old question, but I had current problems with this issue. So I provide you my solution. Now the sources and javadocs are inside the jdk. So, unzip your jdk version.You can see that contanins a "src.zip" file. Here are your needed sources and doc files. Follow the path: Window->Preferences->Java->Installed JREs-> select your jre/jrd and press "Edit" Select all .jar files, and press Source Attachement. Select the "External File..." button, and point it to src.zip file.
Maibe a restart to Eclipse is needed. (normally not) Now you should see the docs, and also the sources for the classes from jdk.
This is the easiest solution in my opinion is to select all the element which has certain data attribute:
var data = $("#dataTable[data-timer]");
var diffs = [];
for(var i = 0; i + 1 < data.length; i++) {
diffs[i] = data[i + 1] - data[i];
}
alert(diffs.join(', '));
What you have should work, unless ${STATUS}
is empty. It would probably be better to do:
if ! [ "${STATUS}" -eq 200 ] 2> /dev/null && [ "${STRING}" != "${VALUE}" ]; then
or
if [ "${STATUS}" != 200 ] && [ "${STRING}" != "${VALUE}" ]; then
It's hard to say, since you haven't shown us exactly what is going wrong with your script.
Personal opinion: never use [[
. It suppresses important error messages and is not portable to different shells.
For those who want to access a file from an already loaded PowerShell session, either use Unblock-File to mark the file as safe (though you already need to have set a relaxed execution policy like Unrestricted
for this to work), or change the execution policy just for the current PowerShell session:
Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process
With the WebClient class:

I figured it out already:
as.data.frame.matrix(mytable)
does what I need -- apparently, the table needs to somehow be converted to a matrix in order to be appropriately translated into a data frame. I found more details on this as.data.frame.matrix() function for contingency tables at the Computational Ecology blog.
SHOW TABLE STATUS WHERE Name = 'xxx'
This will give you (among other things) an Engine
column, which is what you want.
If you have a fixed div
just absolute position it at 50% from the top and 50% left and negative margin top and left of half the height and width respectively. Adjust to your needs:
div {
position: absolute;
top: 50%;
left: 50%;
width: 500px;
height: 300px;
margin-left: -250px;
margin-top: -150px;
}
one liner
var date = DateTime.Now.Date.Add(new TimeSpan(4, 30, 0));
would bring back todays date with a time of 4:30:00, replace DateTime.Now with any date object
Here are some examples:

1 5 1 NA 1
2 6 2 3 2
3 7 3 2 3
4 8 4 1 4
>
> weight <- c(1, 2) # x * 1/3 + y * 2/3
> z$wmean <- apply(subset(z, select = c(x, y)), 1, function(d) weighted.mean(d, weight, na.rm = TRUE))

Consult the documentation for updates:
No you don't have to put credentials, You have to put headers on client side eg:
$http({
url: 'url of service',
method: "POST",
data: {test : name },
withCredentials: true,
headers: {
'Content-Type': 'application/json; charset=utf-8'
}
});
And and on server side you have to put headers to this is example for nodejs:
/**
* On all requests add headers
*/
app.all('*', function(req, res,next) {
/**
* Response settings
* @type {Object}
*/
var responseSettings = {
"AccessControlAllowOrigin": req.headers.origin,
"AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Date, X-Api-Version, X-File-Name",
"AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
"AccessControlAllowCredentials": true
};
/**
* Headers
*/
res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
res.header("Access-Control-Allow-Origin", responseSettings.AccessControlAllowOrigin);
res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);
if ('OPTIONS' == req.method) {

Googled for Retrieve unsaved Scripts and found a solution.
Run the following select
script. It provides a list of scripts and its time of execution in the last 24 hours. This will be helpful to retrieve the scripts, if we close our query window in SQL Server management studio without saving the script. It works for all executed scripts not only a view or procedure.
Use <database>
SELECT execquery.last_execution_time AS [Date Time], execsql.text AS [Script] FROM sys.dm_exec_query_stats AS execquery
CROSS APPLY sys.dm_exec_sql_text(execquery.sql_handle) AS execsql
ORDER BY execquery.last_execution_time DESC
The suggested for loop is quite fine but you have to check the properties with hasOwnProperty

In Swift 4, as String
is a collection of Character
, you need to use map
let array1 = Array("hello") // Array<Character>
let array2 = Array("hello").map({ "\($0)" }) // Array<String>
let array3 = "hello".map(String.init) // Array<String>
I haven't worked much with Appcelerator Titanium, but I'll put my understanding of it at the end.
I can speak a bit more to the differences between PhoneGap and Xamarin, as I work with these two 5 (or more) days a week.
If you are already familiar with C# and JavaScript, then the question I guess is, does the business logic lie in an area more suited to JavaScript or C#?
PhoneGap is designed to allow you to write your applications using JavaScript and HTML, and much of the functionality that they do provide is designed to mimic the current proposed specifications for the functionality that will eventually be available with HTML5. The big benefit of PhoneGap in my opinion is that since you are doing the UI with HTML, it can easily be ported between platforms. The downside is, because you are porting the same UI between platforms, it won't feel quite as at home in any of them. Meaning that, without further tweaking, you can't have an application that feels fully at home in iOS and Android, meaning that it has the iOS and Android styling. The majority of your logic can be written using JavaScript, which means it too can be ported between platforms. If the current PhoneGap API does most of what you want, then it's pretty easy to get up and running. If however, there are things you need from the device that are not in the API, then you get into the fun of Plugin Development, which will be in the native device's development language of choice (with one caveat, but I'll get to that), which means you would likely need to get up to speed quickly in Objective-C, Java, etc. The good thing about this model, is you can usually adapt many different native libraries to serve your purpose, and many libraries already have PhoneGap Plugins. Although you might not have much experience with these languages, there will at least be a plethora of examples to work from.
Xamarin.iOS and Xamarin.Android (also known as MonoTouch and MonoDroid), are designed to allow you to have one library of business logic, and use this within your application, and hook it into your UI. Because it's based on .NET 4.5, you get some awesome lambda notations, LINQ, and a whole bunch of other C# awesomeness, which can make writing your business logic less painful. The downside here is that Xamarin expects that you want to make your applications truly feel native on the device, which means that you will likely end up rewriting your UI for each platform, before hooking it together with the business logic. I have heard about MvvmCross, which is designed to make this easier for you, but I haven't really had an opportunity to look into it yet. If you are familiar with the MVVM system in C#, you may want to have a look at this. When it comes to native libraries, MonoTouch becomes interesting. MonoTouch requires a Binding library to tell your C# code how to link into the underlying Objective-C and Java code. Some of these libraries will already have bindings, but if yours doesn't, creating one can be, interesting. Xamarin has made a tool called Objective Sharpie to help with this process, and for the most part, it will get you 95% of the way there. The remaining 5% will probably take 80% of your time attempting to bind a library.
Update
As noted in the comments below, Xamarin has released Xamarin Forms which is a cross platform abstraction around the platform specific UI components. Definitely worth the look.
Now because I said I would get to it, the caveat mentioned in PhoneGap above, is a Hybrid approach, where you can use PhoneGap for part, and Xamarin for part. I have quite a bit of experience with this, and I would caution you against it. Highly. The problem with this, is it is such a no mans' land that if you ever run into issues, almost no one will have come close to what you're doing, and will question what you're trying to do greatly. It is doable, but it's definitely not fun.
As I mentioned before, I haven't worked much with Appcelerator Titanium, So for the differences between them, I will suggest you look at Comparing Titanium and Phonegap or Comparison between Corona, Phonegap, Titanium as it has a very thorough description of the differences. Basically, it appears that though they both use JavaScript, how that JavaScript is interpreted is slightly different. With Titanium, you will be writing your JavaScript to the Titanium SDK, whereas with PhoneGap, you will write your application using the PhoneGap API. As PhoneGap is very HTML5 and JavaScript standards compliant, you can use pretty much any JavaScript libraries you want, such as JQuery. With PhoneGap your user interface will be composed of HTML and CSS. With Titanium, you will benefit from their Cross-platform XML which appears to generate Native components. This means it will definitely have a better native look and feel.
Try using the command: git status
as noted here, this is what worked best for me:
sudo apt-get install python3 python3-pip python3-setuptools
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
The Easiest way to implement scrollbar using java swing is as below :
Getting only the "major" build #:
java -version 2>&1 | head -n 1 | awk -F'["_.]' '{print $3}'
In general, it is considered best-practice to use relative URLs, so that your website will not be bound to the base URL of where it is currently deployed. For example, it will be able to work on localhost, as well as on your public domain, without modifications.
Python 3+:
inv_map = {v: k for k, v in my_map.items()}
Python 2:
inv_map = {v: k for k, v in my_map.iteritems()}
Warning! Your SQL isn't a good idea, because it will select all rows (no WHERE clause assumes "WHERE 1"!) and clog your application if you have a large number of rows. (What's the point of selecting 1,000 rows when 1 will do?) So instead, when selecting only one row, make sure you specify the LIMIT clause:
$sql = "SELECT id FROM games LIMIT 1"; // Select ONLY one, instead of all
$result = $db->query($sql);
$row = $result->fetch_assoc();
echo 'Game ID: '.$row['id'];
This difference requires MySQL to select only the first matching record, so ordering the table is important or you ought to use a WHERE clause. However, it's a whole lot less memory and time to find that one record, than to get every record and output row number one.
Something like this:
if($('#postageyes').is(':checked')) {
// do stuff
}
I believe Nginx dont take in account Docker resolver (127.0.0.11), so please, can you try adding:

:-) Sunday | 0 -> Sun
|
Monday | 1 -> Mon
Tuesday | 2 -> Tue
Wednesday | 3 -> Wed
Thursday | 4 -> Thu
Friday | 5 -> Fri
Saturday | 6 -> Sat
|
:-) Sunday | 7 -> Sun
As you can see above, and as said before, the numbers 0
and 7
are both assigned to Sunday. There are also the English abbreviated days of the week listed, which can also be used in the crontab.
Examples of Number or Abbreviation Use
15 09 * * 5,6,0 command
15 09 * * 5,6,7 command
15 09 * * 5-7 command
15 09 * * Fri,Sat,Sun command
The four examples do all the same and execute a command every Friday, Saturday, and Sunday at 9.15 o'clock.
In Detail
Having two numbers 0
and 7
for Sunday can be useful for writing weekday ranges starting with 0
or ending with 7
. So you can write ranges starting with Sunday or ending with it, like 0-2
or 5-7
for example (ranges must start with the lower number and must end with the higher). The abbreviations cannot be used to define a weekday range.
I found the problem that was causing the HTTP error.
In the setFalse()
function that is triggered by the Save button my code was trying to submit the form that contained the button.
function setFalse(){
document.getElementById("hasId").value ="false";
document.deliveryForm.submit();

when I remove the document.submitForm.submit();
it works:
function setFalse(){
document.getElementById("hasId").value ="false";
document.deliveryForm.submit()
@Roger Lindsjö Thank you for spotting my error where I wasn't passing on the right parameter!
No, there is not.
First of all, SQL injection is an input filtering problem, and XSS is an output escaping one - so you wouldn't even execute these two operations at the same time in the code lifecycle.
Basic rules of thumb
mysql_real_escape_string()
)strip_tags()
to filter out unwanted HTMLhtmlspecialchars()
and be mindful of the 2nd and 3rd parameters here.I use Apache common's DurationFormatUtils like so:
DurationFormatUtils.formatDuration(millis, "**H:mm:ss**", true);
Solution #1: Your statement
.Range(Cells(RangeStartRow, RangeStartColumn), Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues
does not refer to a proper Range
to act upon. Instead,
.Range(.Cells(RangeStartRow, RangeStartColumn), .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues
does (and similarly in some other cases).
Solution #2:
Activate Worksheets("Cable Cards")
prior to using its cells.
Explanation:
Cells(RangeStartRow, RangeStartColumn)
(e.g.) gives you a Range
, that would be ok, and that is why you often see Cells
used in this way. But since it is not applied to a specific object, it applies to the ActiveSheet
. Thus, your code attempts using .Range(rng1, rng2)
, where .Range
is a method of one Worksheet
object and rng1
and rng2
are in a different Worksheet
.
There are two checks that you can do to make this quite evident:
Activate your Worksheets("Cable Cards")
prior to executing your Sub
and it will start working (now you have well-formed references to Range
s). For the code you posted, adding .Activate
right after With...
would indeed be a solution, although you might have a similar problem somewhere else in your code when referring to a Range
in another Worksheet
.
With a sheet other than Worksheets("Cable Cards")
active, set a breakpoint at the line throwing the error, start your Sub
, and when execution breaks, write at the immediate window
Debug.Print Cells(RangeStartRow, RangeStartColumn).Address(external:=True)
Debug.Print .Cells(RangeStartRow, RangeStartColumn).Address(external:=True)
and see the different outcomes.
Conclusion:
Using Cells
or Range
without a specified object (e.g., Worksheet
, or Range
) might be dangerous, especially when working with more than one Sheet
, unless one is quite sure about what Sheet
is active.
The above code didn't work for me. The following approach worked.
Create an Intent object with appropriate info and then check if the Intent is callable or not using the following function:
private boolean isCallable(Intent intent) {
List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
}
I suspect its a new feature since this post was created - pass parameters to the script block using $Using:var. Then its a simple mater to pass parameters provided the script is already on the machine or in a known network location relative to the machine
Taking the main example it would be:
icm -cn $Env:ComputerName {
C:\Scripts\ArchiveEventLogs\ver5\ArchiveEventLogs.ps1 -one "uno" -two "dos" -Debug -Clear $Using:Clear
}
I don't know which version of Python you are using but I tried this in Python 3 and made a few changes and it looks like it works. The raw_input function seems to be the issue here. I changed all the raw_input functions to "input()" and I also made minor changes to the printing to be compatible with Python 3. AJ Uppal is correct when he says that you shouldn't name a variable and a function with the same name. See here for reference:
TypeError: 'int' object is not callable

I noticed a small bug in your code as well. This function should ideally convert pounds to kilograms but it looks like when it prints, it is printing "Centimeters" instead of kilograms.
def convertPK():
input_P = float(input(("Pounds: ")))
P_conv = input_P * 0.45
# Printing error in the line below
print("Centimeters: {P_conv}\n")

I was able to read a 4GB log file in about 50 seconds with the following. You may be able to make it faster by loading it as a C# assembly dynamically using PowerShell.
[System.IO.StreamReader]$sr = [System.IO.File]::Open($file, [System.IO.FileMode]::Open)
while (-not $sr.EndOfStream){
$line = $sr.ReadLine()
}
$sr.Close()
In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.
You can try this sample code:
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" android:id="@+id/rootLayout">
<Button
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MOVE" android:layout_centerHorizontal="true"/>
<ImageView
android:id="@+id/img1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
<ImageView
android:id="@+id/img2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
<ImageView
android:id="@+id/img3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">
<ImageView
android:id="@+id/img4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
</LinearLayout>
</RelativeLayout>
Your activity
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
{
@Override
public void onClick(View v)
{
ImageView img = (ImageView) findViewById( R.id.img1 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img2 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img3 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img4 );
moveViewToScreenCenter( img );
}
});
}
private void moveViewToScreenCenter( View view )
{
RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
DisplayMetrics dm = new DisplayMetrics();
this.getWindowManager().getDefaultDisplay().getMetrics( dm );
int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();
int originalPos[] = new int[2];
view.getLocationOnScreen( originalPos );
int xDest = dm.widthPixels/2;
xDest -= (view.getMeasuredWidth()/2);
int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;
TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
anim.setDuration(1000);
anim.setFillAfter( true );
view.startAnimation(anim);
}
The method moveViewToScreenCenter
gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset
variable measures the status bar height.
I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.
java.time.LocalDate
From Java 1.8, you can use the method lengthOfMonth
on java.time.LocalDate
:
LocalDate date = LocalDate.of(2010, 1, 19);
int days = date.lengthOfMonth();
You can use text-align: center; line-height: 65px;
CSS
.loginBtn {
background:url(images/loginBtn-center.jpg) repeat-x;
width:175px;
height:65px;
margin:20px auto;
border-radius:10px;
-webkit-border-radius:10px;
box-shadow:0 1px 2px #5e5d5b;
text-align: center; <--------- Here
line-height: 65px; <--------- Here
}
First is you have to understand the difference between MyISAM
and InnoDB
Engines. And this is clearly stated on this link. You can use this sql statement if you want to convert InnoDB to MyISAM:
ALTER TABLE t1 ENGINE=MyISAM;
Vertical alignment doesn't work with floated elements, indeed. That's because float lifts the element from the normal flow of the document. You might want to use other vertical aligning techniques, like the ones based on transform, display: table, absolute positioning, line-height, js (last resort maybe) or even the plain old html table (maybe the first choice if the content is actually tabular). You'll find that there's a heated debate on this issue.
However, this is how you can vertically align YOUR 3 divs:
.wrap{
width: 500px;
overflow:hidden;
background: pink;
}
.left {
width: 150px;
margin-right: 10px;
background: yellow;
display:inline-block;
vertical-align: middle;
}
.left2 {
width: 150px;
margin-right: 10px;
background: aqua;
display:inline-block;
vertical-align: middle;
}
.right{
width: 150px;
background: orange;
display:inline-block;
vertical-align: middle;
}
Not sure why you needed both fixed width, display: inline-block and floating.
When you use a custom view in a ListView
you must define the row layout.
You create an xml where you place android widgets and then in the adapter's code you have to do something like this:
public MyAdapter(Context context, List<MyObject> objects) extends ArrayAdapter {
super(context, 1, objects);
/* We get the inflator in the constructor */
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
/* We inflate the xml which gives us a view */
view = mInflater.inflate(R.layout.my_list_custom_row, parent, false);
/* Get the item in the adapter */
MyObject myObject = getItem(position);
/* Get the widget with id name which is defined in the xml of the row */
TextView name = (TextView) view.findViewById(R.id.name);
/* Populate the row's xml with info from the item */
name.setText(myObject.getName());
/* Return the generated view */
return view;
}
Read more in the official documentation.
You can try, (filtering with 1 object like a list or a set of values)
ds = ds.filter(functions.col(COL_NAME).isin(myList));
or as @Tony Fraser suggested, you can try, (with a Seq of objects)
ds = ds.filter(functions.col(COL_NAME).isin(mySeq));
All the answers are correct but most of them do not represent a good coding style. Also, you should always consider the variable length of arguments for the future, even though they are static at a certain point in time.
Change the file extension of your css file to .less
. You don't need to write any LESS in it; all CSS is valid LESS (except of the MS stuff that you have to escape, but that's another issue.)
Per Fractalf's answer this is fixed in v1.4.0
I am using ipinfodb.com
api and getting exactly what you are looking for.
Its completely free, you just need to register with them to get your api key. You can include their php class by downloading from their website or you can use url format to retrieve information.
Here's what I am doing:
I included their php class in my script and using the below code:
$ipLite = new ip2location_lite;
$ipLite->setKey('your_api_key');
if(!$_COOKIE["visitorCity"]){ //I am using cookie to store information
$visitorCity = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
if ($visitorCity['statusCode'] == 'OK') {
$data = base64_encode(serialize($visitorCity));
setcookie("visitorCity", $data, time()+3600*24*7); //set cookie for 1 week
}
}
$visitorCity = unserialize(base64_decode($_COOKIE["visitorCity"]));
echo $visitorCity['countryName'].' Region'.$visitorCity['regionName'];
Thats it.
A browser's default styles are defined in its user agent stylesheet, the sources of which you can find here. Unfortunately, the Cascading and Inheritance level 3 spec does not appear to propose a way to reset a style property to its browser default. However there are plans to reintroduce a keyword for this in Cascading and Inheritance level 4 — the working group simply hasn't settled on a name for this keyword yet (the link currently says revert
, but it is not final). Information about browser support for revert
can be found on caniuse.com.
While the level 3 spec does introduce an initial
keyword, setting a property to its initial value resets it to its default value as defined by CSS, not as defined by the browser. The initial value of display
is inline
; this is specified here. The initial
keyword refers to that value, not the browser default. The spec itself makes this note under the all
property:
For example, if an author specifies
all: initial
on an element it will block all inheritance and reset all properties, as if no rules appeared in the author, user, or user-agent levels of the cascade.This can be useful for the root element of a "widget" included in a page, which does not wish to inherit the styles of the outer page. Note, however, that any "default" style applied to that element (such as, e.g.
display: block
from the UA style sheet on block elements such as<div>
) will also be blown away.
So I guess the only way right now using pure CSS is to look up the browser default value and set it manually to that:
div.foo { display: inline-block; }
div.foo.bar { display: block; }
(An alternative to the above would be div.foo:not(.bar) { display: inline-block; }
, but that involves modifying the original selector rather than an override.)
You could also use DateTime.FromFileTime(finishTime) where finishTme is a long containing the ticks of a time. Or FromFileTimeUtc.
JQuery UI already has this, in my example below I included a maxchar attribute to focus on the next focus-able element (input, select, textarea, button and object) if i typed in the max number of characters
HTML:
text 1 <input type="text" value="" id="txt1" maxchar="5" /><br />
text 2 <input type="text" value="" id="txt2" maxchar="5" /><br />
checkbox 1 <input type="checkbox" value="" id="chk1" /><br />
checkbox 2 <input type="checkbox" value="" id="chk2" /><br />
dropdown 1 <select id="dd1" >
<option value="1">1</option>
<option value="1">2</option>
</select><br />
dropdown 2 <select id="dd2">
<option value="1">1</option>
<option value="1">2</option>
</select>
Javascript:
$(function() {
var focusables = $(":focusable");
focusables.keyup(function(e) {
var maxchar = false;
if ($(this).attr("maxchar")) {
if ($(this).val().length >= $(this).attr("maxchar"))
maxchar = true;
}
if (e.keyCode == 13 || maxchar) {
var current = focusables.index(this),
next = focusables.eq(current+1).length ? focusables.eq(current+1) : focusables.eq(0);
next.focus();
}
});
});
The most similar method to readdir
is probably using the little-known _find
family of functions.
A lookahead regex syntax can help you to achieve your goal. Thus a regex for your example is
.*?quick.*?(?=z)
And it's important to notice the .*?
lazy matching before the (?=z)
lookahead: the expression matches a substring until a first occurrence of the z
letter.
Here is C# code sample:
const string text = "The quick red fox jumped over the lazy brown dogz";
string lazy = new Regex(".*?quick.*?(?=z)").Match(text).Value;
Console.WriteLine(lazy); // The quick red fox jumped over the la
string greedy = new Regex(".*?quick.*(?=z)").Match(text).Value;
Console.WriteLine(greedy); // The quick red fox jumped over the lazy brown dog
How about this, using a simple flag
function checkPalindrom(str){
var flag = true;
for( var i = 0; i <= str.length-1; i++){
if( str[i] !== str[str.length - i-1]){
flag = false;
}
}
if(flag == false){
console.log('the word is not a palindrome!');
}
else{
console.log('the word is a palindrome!');
}
}
checkPalindrom('abcdcba');
Chr(10)
is the Line Feed character and Chr(13)
is the Carriage Return character.
You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.
Historically, Line Feed would move down a line but not return to column 1:
This
is
a
test.
Similarly Carriage Return would return to column 1 but not move down a line:
This
is
a
test.
Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.
Updated answer for Swift 4
let language = Bundle.main.preferredLocalizations.first
The current object is explicitly passed to the method as the first parameter. self
is the conventional name. You can call it anything you want but it is strongly advised that you stick with this convention to avoid confusion.
If we are directly use data from csv it will give combine data based on comma separation value as it is .csv file.
user1 = pd.read_csv('dataset/1.csv')
If you want to add column names using pandas, you have to do something like this. But below code will not show separate header for your columns.
col_names=['TIME', 'X', 'Y', 'Z']
user1 = pd.read_csv('dataset/1.csv', names=col_names)
To solve above problem we have to add extra filled which is supported by pandas, It is header=None
user1 = pd.read_csv('dataset/1.csv', names=col_names, header=None)
I think you'll get what you want with the -maxdepth 1
option, based on your current command structure. If not, you can try looking at the man page for find
.
Relevant entry (for convenience's sake):
-maxdepth levels
Descend at most levels (a non-negative integer) levels of direc-
tories below the command line arguments. `-maxdepth 0' means
only apply the tests and actions to the command line arguments.
Your options basically are:
# Do NOT show hidden files (beginning with ".", i.e., .*):
find DirsRoot/* -maxdepth 0 -type f
Or:
# DO show hidden files:
find DirsRoot/ -maxdepth 1 -type f
Use flatMap. If a value is present, flatMap returns a sequential Stream containing only that value, otherwise returns an empty Stream. So there is no need to use ifPresent()
. Example:
list.stream().map(data -> data.getSomeValue).map(this::getOptinalValue).flatMap(Optional::stream).collect(Collectors.toList());
You can use Date.before() or Date.after() or Date.equals() for date comparison.
Taken from here:
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateDiff {
public static void main( String[] args )
{
compareDates("2017-01-13 00:00:00", "2017-01-14 00:00:00");// output will be Date1 is before Date2
compareDates("2017-01-13 00:00:00", "2017-01-12 00:00:00");//output will be Date1 is after Date2
compareDates("2017-01-13 00:00:00", "2017-01-13 10:20:30");//output will be Date1 is before Date2 because date2 is ahead of date 1 by 10:20:30 hours
compareDates("2017-01-13 00:00:00", "2017-01-13 00:00:00");//output will be Date1 is equal Date2 because both date and time are equal
}
public static void compareDates(String d1,String d2)
{
try{
// If you already have date objects then skip 1
//1
// Create 2 dates starts
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date1 = sdf.parse(d1);
Date date2 = sdf.parse(d2);
System.out.println("Date1"+sdf.format(date1));
System.out.println("Date2"+sdf.format(date2));System.out.println();
// Create 2 dates ends
//1
// Date object is having 3 methods namely after,before and equals for comparing
// after() will return true if and only if date1 is after date 2
if(date1.after(date2)){
System.out.println("Date1 is after Date2");
}
// before() will return true if and only if date1 is before date2
if(date1.before(date2)){
System.out.println("Date1 is before Date2");
}
//equals() returns true if both the dates are equal
if(date1.equals(date2)){
System.out.println("Date1 is equal Date2");
}
System.out.println();
}
catch(ParseException ex){
ex.printStackTrace();
}
}
public static void compareDates(Date date1,Date date2)
{
// if you already have date objects then skip 1
//1
//1
//date object is having 3 methods namely after,before and equals for comparing
//after() will return true if and only if date1 is after date 2
if(date1.after(date2)){
System.out.println("Date1 is after Date2");
}
//before() will return true if and only if date1 is before date2
if(date1.before(date2)){
System.out.println("Date1 is before Date2");
}
//equals() returns true if both the dates are equal
if(date1.equals(date2)){
System.out.println("Date1 is equal Date2");
}
System.out.println();
}
}
As you have it, the argument w
is expecting a value after -w
on the command line. If you are just looking to flip a switch by setting a variable True
or False
, have a look here (specifically store_true and store_false)
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('-w', action='store_true')
where action='store_true'
implies default=False
.
Conversely, you could haveaction='store_false'
, which implies default=True
.
Use \W
which is equivalent to [^a-zA-Z0-9_]
. Check the documentation, https://docs.python.org/2/library/re.html
Import re
s = 'h^&ell`.,|o w]{+orld'
replaced_string = re.sub(r'\W+', '*', s)
output: 'h*ell*o*w*orld'
update: This solution will exclude underscore as well. If you want only alphabets and numbers to be excluded, then solution by nneonneo is more appropriate.
Building on the answer from Sharfi, edit the /etc/my.cnf file and add just this one line:
validate_password_policy=LOW
That should sufficiently neuter the validation as requested by the OP. You will probably want to restart mysqld after this change. Depending on your OS, it would look something like:
sudo service mysqld restart
validate_password_policy takes either values 0, 1, or 2 or words LOW, MEDIUM, and STRONG which correspond to those numbers. The default is MEDIUM (1) which requires passwords contain at least one upper case letter, one lower case letter, one digit, and one special character, and that the total password length is at least 8 characters. Changing to LOW as I suggest here then only will check for length, which if it hasn't been changed through other parameters will check for a length of 8. If you wanted to shorten that length limit too, you could also add validate_password_length in to the my.cnf file.
For more info about the levels and details, see the mysql doc.
For MySQL 8, the property has changed from "validate_password_policy" to "validate_password.policy". See the updated mysql doc for the latest info.
You are using jQuery, right? Separate JavaScript from HTML.
You can use trigger or triggerHandler.
var $myInput = $('#changeProgramatic').on('change', ChangeValue);
var anotherFunction = function() {
$myInput.val('Another value');
$myInput.trigger('change');
};
Moq (and other DynamicProxy-based mocking frameworks) are unable to mock anything that is not a virtual or abstract method.
Sealed/static classes/methods can only be faked with Profiler API based tools, like Typemock (commercial) or Microsoft Moles (free, known as Fakes in Visual Studio 2012 Ultimate /2013 /2015).
Alternatively, you could refactor your design to abstract calls to static methods, and provide this abstraction to your class via dependency injection. Then you'd not only have a better design, it will be testable with free tools, like Moq.
A common pattern to allow testability can be applied without using any tools altogether. Consider the following method:
public class MyClass
{
public string[] GetMyData(string fileName)
{
string[] data = FileUtil.ReadDataFromFile(fileName);
return data;
}
}
Instead of trying to mock FileUtil.ReadDataFromFile
, you could wrap it in a protected virtual
method, like this:
public class MyClass
{
public string[] GetMyData(string fileName)
{
string[] data = GetDataFromFile(fileName);
return data;
}
protected virtual string[] GetDataFromFile(string fileName)
{
return FileUtil.ReadDataFromFile(fileName);
}
}
Then, in your unit test, derive from MyClass
and call it TestableMyClass
. Then you can override the GetDataFromFile
method to return your own test data.
Hope that helps.
We get err_cache_miss error while using the bowser. Its mean there may be a problem with your browser. It due the items in the cache may be unusable or some configurations are not configured correctly. You may get the solution to clear browser data or Check browser extensions and remove extensions which you felt cause the problem or Resetting your browser or Update your browser or Disabling cache system. These are some tricks to come out this error.
In my case I am enabling draggable. It works.
var bootstrapDialog = new BootstrapDialog({
title: 'Message',
draggable: true,
closable: false,
size: BootstrapDialog.SIZE_WIDE,
message: 'Hello World',
buttons: [{
label: 'close',
action: function (dialogRef) {
dialogRef.close();
}
}],
});
bootstrapDialog.open();
Might be it helps you.
You can store favourites with no associated menu in a separate table:
CREATE TABLE FavoriteWithoutMenu
(
FavoriteWithoutMenuId uuid NOT NULL, --Primary key
UserId uuid NOT NULL,
RecipeId uuid NOT NULL,
UNIQUE KEY (UserId, RecipeId)
)
For the asynchronous dispatch case you describe above, you shouldn't need to check if you're on the main thread. As Bavarious indicates, this will simply be queued up to be run on the main thread.
However, if you attempt to do the above using a dispatch_sync()
and your callback is on the main thread, your application will deadlock at that point. I describe this in my answer here, because this behavior surprised me when moving some code from -performSelectorOnMainThread:
. As I mention there, I created a helper function:
void runOnMainQueueWithoutDeadlocking(void (^block)(void))
{
if ([NSThread isMainThread])
{
block();
}
else
{
dispatch_sync(dispatch_get_main_queue(), block);
}
}
which will run a block synchronously on the main thread if the method you're in isn't currently on the main thread, and just executes the block inline if it is. You can employ syntax like the following to use this:
runOnMainQueueWithoutDeadlocking(^{
//Do stuff
});
The key system must have several properties:
One solution that should give you these would be to use a public key signing scheme. Start with a "system hash" (say grab the macs on any NICs, sorted, and the CPU-ID info, plus some other stuff, concatenate it all together and take an MD5 of the result (you really don't want to be handling personally identifiable information if you don't have to)) append the CD's serial number and refuse to boot unless some registry key (or some datafile) has a valid signature for the blob. The user activates the program by shipping the blob to you and you ship back the signature.
Potential issues include that you are offering to sign practically anything so you need to assume someone will run a chosen plain text and/or chosen ciphertext attacks. That can be mitigated by checking the serial number provided and refusing to handle request from invalid ones as well as refusing to handle more than a given number of queries from a given s/n in an interval (say 2 per year)
I should point out a few things: First, a skilled and determined attacker will be able to bypass any and all security in the parts that they have unrestricted access to (i.e. everything on the CD), the best you can do on that account is make it harder to get illegitimate access than it is to get legitimate access. Second, I'm no expert so there could be serious flaws in this proposed scheme.
To change all classes for an element:
document.getElementById("ElementID").className = "CssClass";
To add an additional class to an element:
document.getElementById("ElementID").className += " CssClass";
To check if a class is already applied to an element:
if ( document.getElementById("ElementID").className.match(/(?:^|\s)CssClass(?!\S)/) )
How about
a["abc"] = [1, 2]
This will result in:
>>> a
{'abc': [1, 2]}
Is that what you were looking for?
Ids are supposed to be unique document wide, so you shouldn't have to select based on both. You can assign an element multiple classes though with class="class1 class2"
Use saved_change_to_published?
:
class SomeModel < ActiveRecord::Base
after_update :send_notification_after_change
def send_notification_after_change
Notification.send(…) if (saved_change_to_published? && self.published == true)
end
end
Or if you prefer, saved_change_to_attribute?(:published)
.
Warning
This approach works through Rails 5.1 (but is deprecated in 5.1 and has breaking changes in 5.2). You can read about the change in this pull request.
In your after_update
filter on the model you can use _changed?
accessor. So for example:
class SomeModel < ActiveRecord::Base
after_update :send_notification_after_change
def send_notification_after_change
Notification.send(...) if (self.published_changed? && self.published == true)
end
end
It just works.
"Is it possible to run this service always as when the application pause and anything else?"
Yes.
In the service onStartCommand method return START_STICKY.
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
Start the service in the background using startService(MyService) so that it always stays active regardless of the number of bound clients.
Intent intent = new Intent(this, PowerMeterService.class);
startService(intent);
Create the binder.
public class MyBinder extends Binder {
public MyService getService() {
return MyService.this;
}
}
Define a service connection.
private ServiceConnection m_serviceConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder service) {
m_service = ((MyService.MyBinder)service).getService();
}
public void onServiceDisconnected(ComponentName className) {
m_service = null;
}
};
Bind to the service using bindService.
Intent intent = new Intent(this, MyService.class);
bindService(intent, m_serviceConnection, BIND_AUTO_CREATE);
For your service you may want a notification to launch the appropriate activity once it has been closed.
private void addNotification() {
// create the notification
Notification.Builder m_notificationBuilder = new Notification.Builder(this)
.setContentTitle(getText(R.string.service_name))
.setContentText(getResources().getText(R.string.service_status_monitor))
.setSmallIcon(R.drawable.notification_small_icon);
// create the pending intent and add to the notification
Intent intent = new Intent(this, MyService.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
m_notificationBuilder.setContentIntent(pendingIntent);
// send the notification
m_notificationManager.notify(NOTIFICATION_ID, m_notificationBuilder.build());
}
You need to modify the manifest to launch the activity in single top mode.
android:launchMode="singleTop"
Note that if the system needs the resources and your service is not very active it may be killed. If this is unacceptable bring the service to the foreground using startForeground.
startForeground(NOTIFICATION_ID, m_notificationBuilder.build());
Here is one aditional free Floating Action Button library for Android It has many customizations and requires SDK version 9 and higher
You should use Ctrl+shift+enter when using the =SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE)) that results in {=SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE))} en also works.
It's better to Use feature in html5 5 data Attributes
<script src="http://path.to/widget.js" data-width="200" data-height="200">
</script>
Inside the script file http://path.to/widget.js you can get the paremeters in that way:
<script>
function getSyncScriptParams() {
var scripts = document.getElementsByTagName('script');
var lastScript = scripts[scripts.length-1];
var scriptName = lastScript;
return {
width : scriptName.getAttribute('data-width'),
height : scriptName.getAttribute('data-height')
};
}
</script>
you can use pow(base, exponent)
from #include <math.h>
or create your own:
int myPow(int x,int n)
{
int i; /* Variable used in loop counter */
int number = 1;
for (i = 0; i < n; ++i)
number *= x;
return(number);
}
try this, calling the activity in the constructor
public class WebService {
private Activity activity;
public WebService(Activity _activity){
activity=_activity;
helper=new Helper(activity);
}
}
.bak
is a backup file generated in SQL Server.
Backup files importing means restoring a database, you can restore on a database created in SQL Server 2012 but the backup file should be from SQL Server 2005, 2008, 2008 R2, 2012 database.
You restore database by using following command...
RESTORE DATABASE YourDB FROM DISK = 'D:BackUpYourBaackUpFile.bak' WITH Recovery
You want to learn about how to restore .bak

Same as all the answers here, but using StreamReader/StreamWriter to split on new lines (line by line, instead of trying to read the whole file into memory at once). This approach can split big files in the fastest way I know of.
Note: I do very little error checking, so I can't guarantee it'll work smoothly for your case. It did for mine (1.7 GB TXT file of 4 million lines split in 100,000 lines per file in 95 seconds).
#split test
$sw = new-object System.Diagnostics.Stopwatch
$sw.Start()
$filename = "C:\Users\Vincent\Desktop\test.txt"
$rootName = "C:\Users\Vincent\Desktop\result"
$ext = ".txt"
$linesperFile = 100000#100k
$filecount = 1
$reader = $null
try{
$reader = [io.file]::OpenText($filename)
try{
"Creating file number $filecount"
$writer = [io.file]::CreateText("{0}{1}.{2}" -f ($rootName,$filecount.ToString("000"),$ext))
$filecount++
$linecount = 0
while($reader.EndOfStream -ne $true) {
"Reading $linesperFile"
while( ($linecount -lt $linesperFile) -and ($reader.EndOfStream -ne $true)){
$writer.WriteLine($reader.ReadLine());
$linecount++
}
if($reader.EndOfStream -ne $true) {
"Closing file"
$writer.Dispose();
"Creating file number $filecount"
$writer = [io.file]::CreateText("{0}{1}.{2}" -f ($rootName,$filecount.ToString("000"),$ext))
$filecount++
$linecount = 0
}
}
} finally {
$writer.Dispose();
}
} finally {
$reader.Dispose();
}
$sw.Stop()
Write-Host "Split complete in " $sw.Elapsed.TotalSeconds "seconds"
Output splitting a 1.7 GB file:
...

This handles not only accents, but also "strokes" (as in ø etc.):
import unicodedata as ud
def rmdiacritics(char):
'''
Return the base character of char, by "removing" any
diacritics like accents or curls and strokes and the like.
'''
desc = ud.name(char)
cutoff = desc.find(' WITH ')
if cutoff != -1:
desc = desc[:cutoff]
try:
char = ud.lookup(desc)
except KeyError:
pass # removing "WITH ..." produced an invalid name
return char
This is the most elegant way I can think of (and it has been mentioned by alexis in a comment on this page), although I don't think it is very elegant indeed. In fact, it's more of a hack, as pointed out in comments, since Unicode names are – really just names, they give no guarantee to be consistent or anything.
There are still special letters that are not handled by this, such as turned and inverted letters, since their unicode name does not contain 'WITH'. It depends on what you want to do anyway. I sometimes needed accent stripping for achieving dictionary sort order.
Incorporated suggestions from the comments (handling lookup errors, Python-3 code).
On Raspberry Pi I had to install php5 mysql extension.
apt-get install php5-mysql
After installing the client, the webserver should be restarted. In case you're using apache, the following should work:
sudo service apache2 restart
Here is complete console working application code. Please install RestSharp package.

I had to use:
find / -name expect 2>/dev/null
specifying the name of what I wanted to find and then telling it to redirect all errors to /dev/null
expect being the location of the expect program I was searching for.
c_str() converts a C++ string into a C-style string which is essentially a null terminated array of bytes. You use it when you want to pass a C++ string into a function that expects a C-style string (e.g. a lot of the Win32 API, POSIX style functions, etc).
Swift
import Foundation
extension String {
func fromBase64() -> String? {
guard let data = Data(base64Encoded: self) else {
return nil
}
return String(data: data, encoding: .utf8)
}
func toBase64() -> String {
return Data(self.utf8).base64EncodedString()
}
}
Try using os.system
:
os.system("script2.py 1")
execfile
is different because it is designed to run a sequence of Python statements in the current execution context. That's why sys.argv
didn't change for you.
Programs to monitor if a process on a system is running.
Script is stored in crontab
and runs once every minute.
#! /bin/bash

If process is not found, restart it.
1
If process is found, all ok.
*
If process running 2 or more, kill the last.
It just tests the exit flag $?
from the pidof
program. It will be 0
of process is running and 1
if not.
#!/bin/bash

You could use streams in Java 8. To always get 10 entries at the most, you could do:
dataList.stream().skip(5).limit(10).collect(Collectors.toList());
dataList.stream().skip(30).limit(10).collect(Collectors.toList());
I was having the same problem, it has a very simple solution.
Steps for executing the 'Lex' program:
On Mac, Shift+CMD+F for search and replace. Search for '\n' and replace with Shift+Enter.
fmin
and fmax
, of fminl
and fmaxl
could be preferred when comparing signed and unsigned integers - you can take advantage of the fact that the entire range of signed and unsigned numbers and you don't have to worry about integer ranges and promotions.
unsigned int x = 4000000000;
int y = -1;
int z = min(x, y);
z = (int)fmin(x, y);
As to me, i need to caffe to my python path. I can add it's path to the file
/home/xy/.bashrc
by add
export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH
.
to my /home/xy/.bashrc
file.
But when I use pycharm, the path is still not in.
So I can add path to PYTHONPATH
variable, by run -> edit Configuration.
To debug php with vscode,you need these things:
you can gently walk through step 1 and 2,by following the vscode official guide.It is fully recommended to use XDebug installation wizard to verify your XDebug configuration.
If you want to debug without a standalone web server,the php built-in maybe a choice.Start the built-in server by php -S localhost:port -t path/to/your/project
command,setting your project dir as document root.You can refer to this post for more details.
Try the different values for Graphics.InterpolationMode. There are several typical scaling algorithms available in GDI+. If one of these is sufficient for your need, you can go this route instead of relying on an external library.
