Best practice: one form per product is definitely the way to go.
Benefits:
In your specific situation
If you only ever intend to have one form element, in this case a submit
button, one form for all should work just fine.
My recommendation Do one form per product, and change your markup to something like:
<form method="post" action="">
<input type="hidden" name="product_id" value="123">
<button type="submit" name="action" value="add_to_cart">Add to Cart</button>
</form>
This will give you a much cleaner and usable POST
. No parsing. And it will allow you to add more parameters in the future (size, color, quantity, etc).
Note: There's no technical benefit to using
<button>
vs.<input>
, but as a programmer I find it cooler to work withaction=='add_to_cart'
thanaction=='Add to Cart'
. Besides, I hate mixing presentation with logic. If one day you decide that it makes more sense for the button to say "Add" or if you want to use different languages, you could do so freely without having to worry about your back-end code.
You can't use variable names to bind columns or other system objects, you need dynamic sql
DECLARE @value varchar(10)
SET @value = 'intStep'
DECLARE @sqlText nvarchar(1000);
SET @sqlText = N'SELECT ' + @value + ' FROM dbo.tblBatchDetail'
Exec (@sqlText)
I think the problem is that you load
isfar
data.frame but you overwrite it by value returned by load
.
Try either:
load("C:/Users/isfar.RData")
head(isfar)
Or more general way
load("C:/Users/isfar.RData", ex <- new.env())
ls.str(ex)
Material UI have implemented their own Flexbox layout via the Grid component.
It appears they initially wanted to keep themselves as purely a 'components' library. But one of the core developers decided it was too important not to have their own. It has now been merged into the core code and was released with v1.0.0.
You can install it via:
npm install @material-ui/core
It is now in the official documentation with code examples.
You can use Group by All but be careful as Group by All will be removed from future versions of SQL server.
According to the JavaDoc for the .contains(Object obj)
:
Returns true if this list contains the specified element. More formally, returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e)).
So if you override your .equals()
method for your given object, you should be able to do: if(list1.contains(object2))...
If the elements will be unique (ie. have different attributes) you could override the .equals()
and .hashcode()
and store everything in HashSets
. This will allow you to check if one contains another element in constant time.
There are codes for other space characters, and the codes as such work well, but the characters themselves are legacy character. They have been included into character sets only due to their presence in existing character data, rather than for use in new documents. For some combinations of font and browser version, they may cause a generic glyph of unrepresentable character to be shown. For details, check my page about Unicode spaces.
So using CSS is safer and lets you specify any desired amount of spacing, not just the specific widths of fixed-width spaces. If you just want to have added spacing around your h2 elements, as it seems to me, then setting padding on those elements (changing the value of the padding: 0 settings that you already have) should work fine.
Alternatively, you can just do:
import matplotlib as mpl
label_size = 8
mpl.rcParams['xtick.labelsize'] = label_size
pgrep -f process_name > any_file_name
sed -i 's/^/kill /' any_file_name
chmod 777 any_file_name
./any_file_name
for example 'pgrep -f firefox' will grep the PID of running 'firefox' and will save this PID to a file called 'any_file_name'. 'sed' command will add the 'kill' in the beginning of the PID number in 'any_file_name' file. Third line will make 'any_file_name' file executable. Now forth line will kill the PID available in the file 'any_file_name'. Writing the above four lines in a file and executing that file can do the control-C. Working absolutely fine for me.
I solved the same problem, I used a network connection through a proxy server, when I selected the option not to use proxies for internal and local connections, the problem disappeared
The .cpp file is the compilation unit : it's the real source code file that will be compiled (in C++).
The .h (header) files are files that will be virtually copy/pasted in the .cpp files where the #include precompiler instruction appears. Once the headers code is inserted in the .cpp code, the compilation of the .cpp can start.
BigInteger has a constructor where you can pass string as an argument.
try below,
private void sum(String newNumber) {
// BigInteger is immutable, reassign the variable:
this.sum = this.sum.add(new BigInteger(newNumber));
}
Inherit the tableview delegate and datasource. Implement delegates what you need.
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
And Finally implement this delegate
func tableView(_ tableView: UITableView, didSelectRowAt
indexPath: IndexPath) {
print("row selected : \(indexPath.row)")
}
First want to credit @emil-ingerslev for an awesome answer. I tested it and it worked perfectly. There were two things however I wanted to improve.
<iframe id="ifmcontentstoprint" style="height: 0px; width: 0px; position: absolute"></iframe>
already in the dom tree.I hope this makes others happy and saves a few minutes of life. Now go take those extra minutes and do something nice for someone.
function printPartOfPage(elementId, uniqueIframeId){
const content = document.getElementById(elementId)
let pri
if (document.getElementById(uniqueIframeId)) {
pri = document.getElementById(uniqueIframeId).contentWindow
} else {
const iframe = document.createElement('iframe')
iframe.setAttribute('title', uniqueIframeId)
iframe.setAttribute('id', uniqueIframeId)
iframe.setAttribute('style', 'height: 0px; width: 0px; position: absolute;')
document.body.appendChild(iframe)
pri = iframe.contentWindow
}
pri.document.open()
pri.document.write(content.innerHTML)
pri.document.close()
pri.focus()
pri.print()
}
EDIT 2019-7-23: After using this more, this does have the downside that it doesn't perfectly render react components. This worked for me when the styling was inline but not when handled by styled-components or some other situations. If I come up with a foolproof method I will update.
For unmanaged types aka value types, structs:
Marshal.SizeOf(object);
For managed objects the closer i got is an approximation.
long start_mem = GC.GetTotalMemory(true);
aclass[] array = new aclass[1000000];
for (int n = 0; n < 1000000; n++)
array[n] = new aclass();
double used_mem_median = (GC.GetTotalMemory(false) - start_mem)/1000000D;
Do not use serialization.A binary formatter adds headers, so you can change your class and load an old serialized file into the modified class.
Also it won't tell you the real size in memory nor will take into account memory alignment.
[Edit] By using BiteConverter.GetBytes(prop-value) recursivelly on every property of your class you would get the contents in bytes, that doesn't count the weight of the class or references but is much closer to reality. I would recommend to use a byte array for data and an unmanaged proxy class to access values using pointer casting if size matters, note that would be non-aligned memory so on old computers is gonna be slow but HUGE datasets on MODERN RAM is gonna be considerably faster, as minimizing the size to read from RAM is gonna be a bigger impact than unaligned.

Plain JavaScript is the best pick for small onetimers.
On the other hand, if you need more date stuff, MomentJS is a great solution.
For example:
moment().format('YYYY-MM-DD HH:m:s'); // now() -> 2015-03-24 14:32:20
moment("20111031", "YYYYMMDD").fromNow(); // 3 years ago
moment("20120620", "YYYYMMDD").fromNow(); // 3 years ago
moment().startOf('day').fromNow(); // 11 hours ago
moment().endOf('day').fromNow(); // in 13 hours
Because you are asking the compiler to initialize a static variable with code that is inherently dynamic.
NSArray *directoryPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *imagePath = [directoryPath objectAtIndex:0];
//If you have superate folder
imagePath= [imagePath stringByAppendingPathComponent:@"ImagesFolder"];//Get docs dir path with folder name
_imageName = [_imageName stringByAppendingString:@".jpg"];//Assign image name
imagePath= [imagePath stringByAppendingPathComponent:_imageName];
NSLog(@"%@", imagePath);
//Method 1:
BOOL file = [[NSFileManager defaultManager] fileExistsAtPath: imagePath];
if (file == NO){
NSLog("File not exist");
} else {
NSLog("File exist");
}
//Method 2:
NSData *data = [NSData dataWithContentsOfFile:imagePath];
UIImage *image = [UIImage imageWithData:data];
if (!(image == nil)) {//Check image exist or not
cell.photoImageView.image = image;//Display image
}
In Laravel 5 simply:

You can filter all characters from the string that are not printable using string.printable, like this:
>>> s = "some\x00string. with\x15 funny characters"
>>> import string
>>> printable = set(string.printable)
>>> filter(lambda x: x in printable, s)
'somestring. with funny characters'
string.printable on my machine contains:
0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c
EDIT: On Python 3, filter will return an iterable. The correct way to obtain a string back would be:
''.join(filter(lambda x: x in printable, s))
tested on IE11, FF53, GC58 :
onclick="var e=this;setTimeout(function(){e.disabled=true;},0);return true;"
You can get and set environment variables via os.environ
:
import os
user_home = os.environ["HOME"]
os.environ["PYTHONPATH"] = "..."
But since your interpreter is already running, this will have no effect. You're better off using
import sys
sys.path.append("...")
which is the array that your PYTHONPATH
will be transformed into on interpreter startup.
I recently had the same problem and found out that I just needed to convert the .py file's charset to UTF-8 as that's the set Python 3 uses.
BTW, I used 4-space tabs all the time, so the problem wasn't caused by them.
Dependencies vs dev dependencies
Dev dependencies are modules which are only required during development whereas dependencies are required at runtime. If you are deploying your application, dependencies has to be installed, or else your app simply will not work. Libraries that you call from your code that enables the program to run can be considered as dependencies.
Eg- React , React - dom
Dev dependency modules need not be installed in the production server since you are not gonna develop in that machine .compilers that covert your code to javascript , test frameworks and document generators can be considered as dev-dependencies since they are only required during development .
Eg- ESLint , Babel , webpack
@FYI,
mod-a
dev-dependents:
- mod-b
dependents:
- mod-c
mod-d
? dev-dependents:
- mod-e
dependents:
- mod-a
----
npm install mod-d
installed modules:
- mod-d
- mod-a
- mod-c
----
checkout the mod-d code repository
npm install
installed modules:
- mod-a
- mod-c
- mod-e
If you are publishing to npm, then it is important that you use the correct flag for the correct modules. If it is something that your npm module needs to function, then use the "--save" flag to save the module as a dependency. If it is something that your module doesn't need to function but it is needed for testing, then use the "--save-dev" flag.
# For dependent modules
?npm install dependent-module --save
?# For dev-dependent modules
np?m install development-module --save-dev
You can use mysql_real_escape_string. mysql_real_escape_string()
does not escape %
and _
, so you should escape MySQL wildcards (%
and _
) separately.
By using a simple pattern based in ES6 WeakMaps is possible to obtain private member variables, reachable from the prototype functions.
Note : The usage of WeakMaps guarantees safety against memory leaks, by letting the Garbage Collector identify and discard unused instances.
// Create a private scope using an Immediately _x000D_
// Invoked Function Expression..._x000D_
let Person = (function() {_x000D_
_x000D_
// Create the WeakMap that will hold each _x000D_
// Instance collection's of private data_x000D_
let privateData = new WeakMap();_x000D_
_x000D_
// Declare the Constructor :_x000D_
function Person(name) {_x000D_
// Insert the private data in the WeakMap,_x000D_
// using 'this' as a unique acces Key_x000D_
privateData.set(this, { name: name });_x000D_
}_x000D_
_x000D_
// Declare a prototype method _x000D_
Person.prototype.getName = function() {_x000D_
// Because 'privateData' is in the same _x000D_
// scope, it's contents can be retrieved..._x000D_
// by using again 'this' , as the acces key _x000D_
return privateData.get(this).name;_x000D_
};_x000D_
_x000D_
// return the Constructor_x000D_
return Person;_x000D_
}());
_x000D_
A more detailed explanation of this pattern can be found here
btn1.setId(1);
addRule()
, check
out the android java docs for this
LayoutParams
object.What we have in our table:-
Primary Key
Event type (e.g. "UPDATED", "APPROVED")
Description ("Frisbar was added to blong")
User Id
User Id of second authoriser
Amount
Date/time
Generic Id
Table Name
The generic id points at a row in the table that was updated and the table name is the name of that table as a string. Not a good DB design, but very usable. All our tables have a single surrogate key column so this works well.
You could use np.isreal
to check the type of each element (applymap applies a function to each element in the DataFrame):
In [11]: df.applymap(np.isreal)
Out[11]:
a b
item
a True True
b True True
c True True
d False True
e True True
If all in the row are True then they are all numeric:
In [12]: df.applymap(np.isreal).all(1)
Out[12]:
item
a True
b True
c True
d False
e True
dtype: bool
So to get the subDataFrame of rouges, (Note: the negation, ~, of the above finds the ones which have at least one rogue non-numeric):
In [13]: df[~df.applymap(np.isreal).all(1)]
Out[13]:
a b
item
d bad 0.4
You could also find the location of the first offender you could use argmin:
In [14]: np.argmin(df.applymap(np.isreal).all(1))
Out[14]: 'd'
As @CTZhu points out, it may be slightly faster to check whether it's an instance of either int or float (there is some additional overhead with np.isreal):
df.applymap(lambda x: isinstance(x, (int, float)))
I know I come late, but only recently I was able to implement such "addHeader" to the Adapter. In my FlexibleAdapter project you can call setHeader
on a Sectionable item, then you call showAllHeaders
. If you need only 1 header then the first item should have the header. If you delete this item, then the header is automatically linked to the next one.
Unfortunately footers are not covered (yet).
The FlexibleAdapter allows you to do much more than create headers/sections. You really should have a look: https://github.com/davideas/FlexibleAdapter.
First, set customErrors = "Off" in the web.config and redeploy to get a more detailed error message that will help us diagnose the problem. You could also RDP into the instance and browse to the site from IIS locally to view the errors.
<system.web>
<customErrors mode="Off" />
First guess though - you have some references (most likely Azure SDK references) that are not set to Copy Local = true. So, all your dependencies are not getting deployed.
Get to the detailed error first and update your question.
UPDATE: A second option now available in VS2013 is Remote Debugging a Cloud Service or Virtual Machine.
If it's just for display purposes, you can render the text as upper or lower case in pure CSS, without any Javascript using the text-transform
property:
.myclass {
text-transform: lowercase;
}
See https://developer.mozilla.org/en/CSS/text-transform for more info.
However, note that this doesn't actually change the value to lower case; it just displays it that way. This means that if you examine the contents of the element (ie using Javascript), it will still be in its original format.
Just putting it in src/main/resources
will bundle it inside the artifact. E.g. if your artifact is a JAR, you will have the log4j.properties
file inside it, losing its initial point of making logging configurable.
I usually put it in src/main/resources
, and set it to be output to target like so:
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<targetPath>${project.build.directory}</targetPath>
<includes>
<include>log4j.properties</include>
</includes>
</resource>
</resources>
</build>
Additionally, in order for log4j to actually see it, you have to add the output directory to the class path.
If your artifact is an executable JAR, you probably used the maven-assembly-plugin to create it. Inside that plugin, you can add the current folder of the JAR to the class path by adding a Class-Path
manifest entry like so:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.your-package.Main</mainClass>
</manifest>
<manifestEntries>
<Class-Path>.</Class-Path>
</manifestEntries>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id> <!-- this is used for inheritance merges -->
<phase>package</phase> <!-- bind to the packaging phase -->
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
Now the log4j.properties file will be right next to your JAR file, independently configurable.
To run your application directly from Eclipse, add the resources
directory to your classpath in your run configuration: Run->Run Configurations...->Java Application->New
select the Classpath
tab, select Advanced
and browse to your src/resources
directory.
EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable
example does not need the mappedBy
annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:
org.hibernate.AnnotationException:
Associations marked as mappedBy must not define database mappings
like @JoinTable or @JoinColumn
Let's pretend that you have an entity named Project
and another entity named Task
and each project can have many tasks.
You can design the database schema for this scenario in two ways.
The first solution is to create a table named Project
and another table named Task
and add a foreign key column to the task table named project_id
:
Project Task
------- ----
id id
name name
project_id
This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:
@Entity
public class Project {
@OneToMany(mappedBy = "project")
private Collection<Task> tasks;
}
@Entity
public class Task {
@ManyToOne
private Project project;
}
The other solution is to use a third table, e.g. Project_Tasks
, and store the relationship between projects and tasks in that table:
Project Task Project_Tasks
------- ---- -------------
id id project_id
name name task_id
The Project_Tasks
table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable
annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:
Project
entity:
@Entity
public class Project {
@Id
@GeneratedValue
private Long pid;
private String name;
@JoinTable
@OneToMany
private List<Task> tasks;
public Long getPid() {
return pid;
}
public void setPid(Long pid) {
this.pid = pid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Task> getTasks() {
return tasks;
}
public void setTasks(List<Task> tasks) {
this.tasks = tasks;
}
}
Task
entity:
@Entity
public class Task {
@Id
@GeneratedValue
private Long tid;
private String name;
public Long getTid() {
return tid;
}
public void setTid(Long tid) {
this.tid = tid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
This will create the following database structure:
The @JoinTable
annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks
property like this:
@JoinTable(
name = "MY_JT",
joinColumns = @JoinColumn(
name = "PROJ_ID",
referencedColumnName = "PID"
),
inverseJoinColumns = @JoinColumn(
name = "TASK_ID",
referencedColumnName = "TID"
)
)
@OneToMany
private List<Task> tasks;
The resulting database would have become:
Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.
You can take a look at the Rails documentation . Anyways , in your form :
<%= f.collection_select :provider_id, Provider.order(:name),:id,:name, include_blank: true %>
As you can guess , you should predefine email-providers in another model -Provider
, to have where to select them from .
How about this, it will read each line to a variable and that can be used subsequently ! say myscript output is redirected to a file called myscript_output
awk '{while ( (getline var < "myscript_output") >0){print var;} close ("myscript_output");}'
To do something after certain div load from function .load()
.
I think this exactly what you need:
$('#divIDer').load(document.URL + ' #divIDer',function() {
// call here what you want .....
//example
$('#mydata').show();
});
Here's a solution where security checking is disabled (for example, conversing with the localhost) Also, some of the solutions I've seen now contain deprecated methods and such.

If you will apply security="none"
then no csrf token will be generated. The page will not pass through security filter. Use role ANONYMOUS.

Structs can have functions just like classes. The only difference is that they are public by default:
struct A {
void f() {}
};
Additionally, structs can also have constructors and destructors.
struct A {
A() : x(5) {}
~A() {}
private: int x;
};
I think servlet is basically a java class which acts as a middle way between HTTP request and HTTP response.Servlet is also used to make your web page dynamic. Suppose for example if you want to redirect to another web page on server then you have to use servlets. Another important thing is that servlet can run on localhost as well as a web browser.
In addition, it's convenient to define variables referring to objects. For instance,
Sub CreateTable()
Dim lo as ListObject
Set lo = ActiveSheet.ListObjects.Add(xlSrcRange, Range("$B$1:$D$16"), , xlYes)
lo.Name = "Table1"
lo.TableStyle = "TableStyleLight2"
...
End Sub
You will probably find it advantageous at once.
keytool -import -v -alias cacerts -keystore cacerts.jks -storepass changeit -file C:\cacerts.cer
One way:
public string GetOSVersion()
{
int _MajorVersion = Environment.OSVersion.Version.Major;
switch (_MajorVersion) {
case 5:
return "Windows XP";
case 6:
switch (Environment.OSVersion.Version.Minor) {
case 0:
return "Windows Vista";
case 1:
return "Windows 7";
default:
return "Windows Vista & above";
}
break;
default:
return "Unknown";
}
}
Then simply do wrap a select case around the function.
This will probably never see the light of day... but here it is anyway.

What error message are you getting?
I'd guess your actual error is because your php variable isn't wrapped in quotes. Try this
$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='" .$somename . "'";
There is a new instance method called String::formatted(Object... args)
as of Java 15.
The internal implementation is same to String::format(String format, Object... args)
.
Formats using this string as the format string, and the supplied arguments.
String step1 = "one";
String step2 = "two";
// results in "Step one of two"
String string = "Step %s of %s".formatted(step1, step2);
Advantage: The difference is that the method is not static
and the formatting pattern is a string itself from which a new one is created based on the args
. This allows chaining to build the format itself first.
Disadvantage: There is no overloaded method with Locale
, therefore uses the default one. If you need to use a custom Locale
, you have to stick with String::format(Locale l,String format,Object... args)
.
Using a terminal command i.e. "clear", in a script called from cron (no terminal) will trigger this error message. In your particular script, the smbmount command expects a terminal in which case the work-arounds above are appropriate.
You could compare String representations so:
array1.toString() == array2.toString()
array1.toString() !== array3.toString()
but that would also make
array4 = ['1',2,3,4,5]
equal to array1 if that matters to you
The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.
See also here: How to supply value to an annotation from a Constant java
It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.
Object properties can be checked for existence by property_exists
Example from a unit test:
function testPropertiesExist()
{
$sl =& $this->system_log;
$props = array('log_id',
'type',
'message',
'username',
'ip_address',
'date_added');
foreach($props as $prop) {
$this->assertTrue(property_exists($sl, $prop),
"Property <{$prop}> exists");
}
}
You should be using IHtmlString
instead:
IHtmlString str = new HtmlString("<a href="/Home/Profile/seeker">seeker</a> has applied to <a href="/Jobs/Details/9">Job</a> floated by you.</br>");
Whenever you have model properties or variables that need to hold HTML, I feel this is generally a better practice. First of all, it is a bit cleaner. For example:
@Html.Raw(str)
Compared to:
@str
Also, I also think it's a bit safer vs. using @Html.Raw()
, as the concern of whether your data is HTML is kept in your controller. In an environment where you have front-end vs. back-end developers, your back-end developers may be more in tune with what data can hold HTML values, thus keeping this concern in the back-end (controller).
I generally try to avoid using Html.Raw()
whenever possible.
One other thing worth noting, is I'm not sure where you're assigning str
, but a few things that concern me with how you may be implementing this.
First, this should be done in a controller, regardless of your solution (IHtmlString
or Html.Raw
). You should avoid any logic like this in your view, as it doesn't really belong there.
Additionally, you should be using your ViewModel
for getting values to your view (and again, ideally using IHtmlString
as the property type). Seeing something like @Html.Encode(str)
is a little concerning, unless you were doing this just to simplify your example.
Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.
I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.
Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.
possibly if you want to just transfer data to be used by JavaScript then you can use Hash Tags like this
http://localhost/project/index.html#exist
so once when you are done retriving the data show the message and change the
window.location.hash to a suitable value.. now whenever you ll refresh the page the hashtag
wont be present
NOTE: when you will use this instead ot query strings the data being sent cannot be retrived/read by the server
Use setOnItemClickListener() api in your activity. Following is the sample.
listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<> parent, View view, int position, long id)
{
// your code here.
}
});

Usage: You can simply get the device model with:
let deviceType = UIDevice().type
or print the exact string with:
print("Running on: \(UIDevice().type)")
Output -> "iPhone X"
Another example with cases:
var myDefaultFontSize: CGFloat = 26.0
switch UIDevice().type {
case .iPhoneSE, .iPhone5, .iPhone5S: print("default value")
case .iPhone6, .iPhone7, .iPhone8, .iPhone6S, .iPhoneX: myDefaultFontSize += 4
default: break
}

I had this issue in VS 2015. The following solved it for me:
Find "webpages:Version" in the appsettings and update it to version 3.0.0.0. My web.config had
<add key="webpages:Version" value="2.0.0.0" />
and I updated it to
<add key="webpages:Version" value="3.0.0.0" />

Just check for the current Facebook user id $user
and if it returned null then you need to reauthorize the user (or use the custom $_SESSION
user id value - not recommended)

$facebook = new Facebook(array(
'appId' => 'APP_ID',

$file='photos/my.jpg'; //Example image file
$photo_details['image'] = '@' . realpath($file);

try {
// We have a valid FB session, so we can use 'me'
$upload_photo = $facebook->api('/me/photos', 'post', $photo_details);
} catch (FacebookApiException $e) {

I've written a tutorial on how to upload a picture to the user's wall.
Suppose you bound your combobox to a List<Person>
List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource
pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;
Of course this means that you need to add a checking code when you try to use the info from the combobox
if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
MessageBox.Show("Please select a person name");
else
......
The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection
In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to
DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);
Or use java.sql.Timestamp. Calendar is kinda heavy,I would recommend against using it in production code. Joda is better.
import java.sql.Timestamp;
public class DateTest {
/**
* @param args
*/
public static void main(String[] args) {
System.out.println(new Timestamp(System.currentTimeMillis()));
}
}

Lots of the answers here don't honor changes of the table or are way too complicated. Using a subclass of UITableView
that will properly set intrinsicContentSize
is a far easier solution when using autolayout. No height constraints etc. needed.
class UIDynamicTableView: UITableView
{
override var intrinsicContentSize: CGSize {
self.layoutIfNeeded()
return CGSize(width: UIViewNoIntrinsicMetric, height: self.contentSize.height)
}
override func reloadData() {
super.reloadData()
self.invalidateIntrinsicContentSize()
}
}
Set the class of your TableView to UIDynamicTableView
in the interface builder and watch the magic as this TableView will change it's size after a call to reloadData()
.
Please consider using Prestyler
import Prestyler
...
Prestyle.defineRule("$", UIColor.red)
label.attributedText = "\(calculatedCoffee) $g$".prestyled()
The Header
property of the TreeViewItem
is statically typed to be of type object
.
Therefore the ==
yields false
. You can reproduce this with the following simple snippet:
object s1 = "Hallo";
// don't use a string literal to avoid interning
string s2 = new string(new char[] { 'H', 'a', 'l', 'l', 'o' });
bool equals = s1 == s2; // equals is false
equals = string.Equals(s1, s2); // equals is true
Explicit conversions are very clear to someone that's new to the language. Using type coercion, as others have suggested, leads to ambiguity if a developer is not aware of the coercion rules. Ultimately developer time is more costly than CPU time, so I'd optimize for the former at the cost of the latter. That being said, in this case the difference is likely negligible, but if not I'm sure there are some decent JavaScript compressors that will optimize this sort of thing.
So, for the above reasons I'd go with: n.toString()
or String(n)
. String(n)
is probably a better choice because it won't fail if n
is null or undefined.

When mysql was installed with Homebrew, the following command did the trick for me:
brew services stop mysql
Try this:
// Hide the login modal
$('#login').modal('hide');
// Show the next modal after the fade effect is finished
setTimeout(function(){ $('#lost').modal('show'); }, 500);
This simple hack works for me.
You have to add CORS on the server side:
If you are using nodeJS then:
First you need to install cors
by using below command :
npm install cors --save
Now add the following code to your app starting file like ( app.js or server.js
)
var express = require('express');
var app = express();
var cors = require('cors');
var bodyParser = require('body-parser');
//enables cors
app.use(cors({
'allowedHeaders': ['sessionId', 'Content-Type'],
'exposedHeaders': ['sessionId'],
'origin': '*',
'methods': 'GET,HEAD,PUT,PATCH,POST,DELETE',
'preflightContinue': false
}));
require('./router/index')(app);
WHERE will filter after the JOIN has occurred.
Filter on the JOIN to prevent rows from being added during the JOIN process.
An interesting observation I made while passing previous state params from one route to another is that $stateParams gets hoisted and overwrites the previous route's state params that were passed with the current state params, but using $state.param
s doesn't.
When using $stateParams
:
var stateParams = {};
stateParams.nextParams = $stateParams; //{item_id:123}
stateParams.next = $state.current.name;
$state.go('app.login', stateParams);
//$stateParams.nextParams on app.login is now:
//{next:'app.details', nextParams:{next:'app.details'}}
When using $state.params:
var stateParams = {};
stateParams.nextParams = $state.params; //{item_id:123}
stateParams.next = $state.current.name;
$state.go('app.login', stateParams);
//$stateParams.nextParams on app.login is now:
//{next:'app.details', nextParams:{item_id:123}}
What Every Computer Scientist Should Know About Floating-Point Arithmetic
Floating-point numbers cannot represent all the numbers. In particular, 2.51 cannot be represented by a floating-point number, and is represented by a number very close to it:
>>> print "%.16f" % 2.51
2.5099999999999998
>>> 2.51*100
250.99999999999997
>>> 4.02*100
401.99999999999994
If you use int, which truncates the numbers, you get:
250
401
Have a look at the Decimal type.

Yes, assuming the account has appropriate permissions you can use:
SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;
You just need to prefix the table reference with the name of the database it resides in.
Spark 1.6.2:
log4j = sc._jvm.org.apache.log4j
log4j.LogManager.getRootLogger().setLevel(log4j.Level.ERROR)
Spark 2.x:
spark.sparkContext.setLogLevel('WARN')
(spark being the SparkSession)
Alternatively the old methods,
Rename conf/log4j.properties.template

So it sounds like the bad commit was incorporated in a merge commit at some point. Has your merge commit been pulled yet? If yes, then you'll want to use git revert
; you'll have to grit your teeth and work through the conflicts. If no, then you could conceivably either rebase or revert, but you can do so before the merge commit, then redo the merge.
There's not much help we can give you for the first case, really. After trying the revert, and finding that the automatic one failed, you have to examine the conflicts and fix them appropriately. This is exactly the same process as fixing merge conflicts; you can use git status
to see where the conflicts are, edit the unmerged files, find the conflicted hunks, figure out how to resolve them, add the conflicted files, and finally commit. If you use git commit
by itself (no -m <message>
), the message that pops up in your editor should be the template message created by git revert
; you can add a note about how you fixed the conflicts, then save and quit to commit.
For the second case, fixing the problem before your merge, there are two subcases, depending on whether you've done more work since the merge. If you haven't, you can simply git reset --hard HEAD^
to knock off the merge, do the revert, then redo the merge. But I'm guessing you have. So, you'll end up doing something like this:
git rebase -i <something before the bad commit> <temporary branch>
to remove the bad commit)git rebase --onto <temporary branch> <old merge commit> <real branch>

You can deploy your angular application on github
using
angular-cli-ghpages
check out the link to find how to deploy using this cli.
the deployed website will be stored in some branch in github
typically
gh-pages
use can clone the git branch and use it like static website in your server

I recommend this for Python 3: Please install it this way with pip
pip3 install opencv-python
This will download and install the latest version of OpenCV.
This is ugly but avoids allocations:
private static string GetFolderName(string path)
{
var end = -1;
for (var i = path.Length; --i >= 0;)
{
var ch = path[i];
if (ch == System.IO.Path.DirectorySeparatorChar ||
ch == System.IO.Path.AltDirectorySeparatorChar ||
ch == System.IO.Path.VolumeSeparatorChar)
{
if (end > 0)
{
return path.Substring(i + 1, end - i - 1);
}
end = i;
}
}
if (end > 0)
{
return path.Substring(0, end);
}
return path;
}
This eclipse documentation has details on the markups in .project
file: The project description file
It describes the .project
file as:
When a project is created in the workspace, a project description file is automatically generated that describes the project. The purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace. This file is always called ".project"
I needed the offset that not only included day light savings time but as a numerial. Here is the code that I used in case someone is looking for an example.
I get a response of "3.5" (3:30') which is what I would expect in Tehran , Iran in winter and "4.5" (4:30') for summer .
I also needed it as a string so I could post it to a server so you may not need the last line.
for getting currect time zone :
TimeZone tz = TimeZone.getDefault();
Date now = new Date();
//Import part : x.0 for double number
double offsetFromUtc = tz.getOffset(now.getTime()) / 3600000.0;
String m2tTimeZoneIs = Double.parseDouble(offsetFromUtc);
In most contexts where double
values are used, calculations will have a certain amount of uncertainty. The difference between 1.33333333333333300 and 1.33333333333333399 may be less than the amount of uncertainty that exists in the calculations. Displaying the value of "2/3 + 2/3" as "1.33333333333333" is apt to be more meaningful than displaying it as "1.33333333333333319", since the latter display implies a level of precision that doesn't really exist.
In the debugger, however, it is important to uniquely indicate the value held by a variable, including essentially-meaningless bits of precision. It would be very confusing if a debugger displayed two variables as holding the value "1.333333333333333" when one of them actually held 1.33333333333333319 and the other held 1.33333333333333294 (meaning that, while they looked the same, they weren't equal). The extra precision shown by the debugger isn't apt to represent a numerically-correct calculation result, but indicates how the code will interpret the values held by the variables.
It's probably worth noting that IE won't cache css files called by other css files using the @import method. So, for example, if your html page links to "master.css" which pulls in "reset.css" via @import, then reset.css will not be cached by IE.
Question 1: Restrict to certain characters
You are right, this is easy to solve with regular expressions:
import re
input_str = raw_input("Please provide some info: ")
if not re.match("^[a-z]*$", input_str):
print "Error! Only letters a-z allowed!"
sys.exit()
Question 2: Restrict to certain length
As Tim mentioned correctly, you can do this by adapting the regular expression in the first example to only allow a certain number of letters. You can also manually check the length like this:
input_str = raw_input("Please provide some info: ")
if len(input_str) > 15:
print "Error! Only 15 characters allowed!"
sys.exit()
Or both in one:
import re
input_str = raw_input("Please provide some info: ")
if not re.match("^[a-z]*$", input_str):
print "Error! Only letters a-z allowed!"
sys.exit()
elif len(input_str) > 15:
print "Error! Only 15 characters allowed!"
sys.exit()
print "Your input was:", input_str
Use the PasteSpecial method:
sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues
BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).
With a running instance of myExecutableName
having a PID 15073
:
hitting Tab twice after $ gdb myExecu
in the command line, will automagically autocompletes to:
$ gdb myExecutableName 15073
and will attach gdb to this process. That's nice!
If you prefer to use the simplest possible solution to a problem, an alternative to RedirectMatch is, the more basic, Redirect directive.
It does not use pattern matching and so is more explicit and easier for others to understand.
i.e
<IfModule mod_alias.c>
#Repoint old contact page to new contact page:
Redirect 301 /contact.php http://example.com/contact-us.php
</IfModule>
Query strings should be carried over because the docs say:
Additional path information beyond the matched URL-path will be appended to the target URL.
I don't often develop in asp.net, however when it comes to loggers I think a lot of best practices are universal. Here are some of my random thoughts on logging that I have learned over the years:
</xxx>
tag, your log is broken.-- Invoking Class: com.foocorp.foopackage.FooClass:9021 SELECT * FROM foo;
This is my logging statement - Repeated 100 times
Also see this question of mine.
You need a dict
:
my_dict = {'cheese': 'cake'}
Example code (from the docs):
>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True
You can read more about dictionaries here.
The most effective way:
if (array.indexOf(element) > -1) {
alert('Bingooo')
}
If your data is from json, you can do that
import json
json.loads('true')
True
HTML Elements
An HTML element usually consists of a start tag and end tag, with the content inserted in between:
<tagname>Content goes here...</tagname>
The HTML element is everything from the start tag to the end tag. Source
HTML Attributes
An attribute is used to define the characteristics of an HTML element and is placed inside the element's opening tag. All attributes are made up of two parts: a name and a value.
HTML Tag vs Element
"Elements" and "tags" are terms that are widely confused. HTML documents contain tags, but do not contain the elements. The elements are only generated after the parsing step, from these tags. Source: wikipedia > HTML_element
An HTML element is defined by a starting tag. If the element contains other content, it ends with a closing tag.
For example <p>
is starting tag of a paragraph and </p>
is closing tag of the same paragraph but <p>This is paragraph</p>
is a paragraph element.

The basic syntax of initializing pointer that points to multidimentional array is
type (*pointer)[1st dimension size][2nd dimension size][..] = &array_name
The the basic syntax for calling it is
(*pointer_name)[1st index][2nd index][...]
Here is a example:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main() {
// The multidimentional array...
char balance[5][100] = {
"Subham",
"Messi"
};
char (*p)[5][100] = &balance; // Pointer initialization...
printf("%s\n",(*p)[0]); // Calling...
printf("%s\n",(*p)[1]); // Calling...
return 0;
}
Output is:
Subham
Messi
It worked...
I know it's not an answer to the exact question asked, but I found this question looking to diff a file in a branch and a local uncommitted file and I figured I would share
Syntax:
git diff <commit-ish>:./ -- <path>
Examples:
git diff origin/master:./ -- README.md
git diff HEAD^:./ -- README.md
git diff stash@{0}:./ -- README.md
git diff 1A2B3C4D:./ -- README.md
(Thanks Eric Boehs for a way to not have to type the filename twice)
You're trying to call an instance method on the class. To call an instance method on a class you must create an instance on which to call the method. If you want to call the method on non-instances add the static keyword. For example
class Example {
public static string NonInstanceMethod() {
return "static";
}
public string InstanceMethod() {
return "non-static";
}
}
static void SomeMethod() {
Console.WriteLine(Example.NonInstanceMethod());
Console.WriteLine(Example.InstanceMethod()); // Does not compile
Example v1 = new Example();
Console.WriteLine(v1.InstanceMethod());
}
var imgSrc, imgW, imgH;
function myFunction(image){
var img = new Image();
img.src = image;
img.onload = function() {
return {
src:image,
width:this.width,
height:this.height};
}
return img;
}
var x = myFunction('http://www.google.com/intl/en_ALL/images/logo.gif');
//Waiting for the image loaded. Otherwise, system returned 0 as both width and height.
x.addEventListener('load',function(){
imgSrc = x.src;
imgW = x.width;
imgH = x.height;
});
x.addEventListener('load',function(){
console.log(imgW+'x'+imgH);//276x110
});
console.log(imgW);//undefined.
console.log(imgH);//undefined.
console.log(imgSrc);//undefined.
This is my method, hope this helpful. :)
Probably it would be easier and neater to close the file after text = re.sub('foobar', 'bar', text)
, re-open it for writing (thus clearing old contents), and write your updated text to it.
ALTER TABLE "Employee" MODIFY ("Salary" NUMERIC(22,5));

You can improve the code by asking the user when the certificate is not valid whether he wants to continue or not. Do you want to continue? As below:
ServicePointManager.ServerCertificateValidationCallback =
new RemoteCertificateValidationCallback(ValidateServerCertificate);
And add a method like this:
public static bool ValidateServerCertificate(object sender,X509Certificate certificate,X509Chain chain,SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == SslPolicyErrors.None)
return true;
else
{
if (System.Windows.Forms.MessageBox.Show("The server certificate is not valid.\nAccept?", "Certificate Validation", System.Windows.Forms.MessageBoxButtons.YesNo, System.Windows.Forms.MessageBoxIcon.Question) == System.Windows.Forms.DialogResult.Yes)
return true;
else
return false;
}

The dataset:
dat <- read.table(text = "A B C D E F G

2 720 350 377 255 340 615 345

4 220 240 876 789 820 100 75", header = TRUE)
Now you can convert the data frame into a matrix and use the barplot
function.

Through this post we are going to draw some lines of differences between VMs and LXCs. Let's first define them.
VM:
A virtual machine emulates a physical computing environment, but requests for CPU, memory, hard disk, network and other hardware resources are managed by a virtualization layer which translates these requests to the underlying physical hardware.
In this context the VM is called as the Guest while the environment it runs on is called the host.
LXCs:
Linux Containers (LXC) are operating system-level capabilities that make it possible to run multiple isolated Linux containers, on one control host (the LXC host). Linux Containers serve as a lightweight alternative to VMs as they don’t require the hypervisors viz. Virtualbox, KVM, Xen, etc.
Now unless you were drugged by Alan (Zach Galifianakis- from the Hangover series) and have been in Vegas for the last year, you will be pretty aware about the tremendous spurt of interest for Linux containers technology, and if I will be specific one container project which has created a buzz around the world in last few months is – Docker leading to some echoing opinions that cloud computing environments should abandon virtual machines (VMs) and replace them with containers due to their lower overhead and potentially better performance.
But the big question is, is it feasible?, will it be sensible?
a. LXCs are scoped to an instance of Linux. It might be different flavors of Linux (e.g. a Ubuntu container on a CentOS host but it’s still Linux.) Similarly, Windows-based containers are scoped to an instance of Windows now if we look at VMs they have a pretty broader scope and using the hypervisors you are not limited to operating systems Linux or Windows.
b. LXCs have low overheads and have better performance as compared to VMs. Tools viz. Docker which are built on the shoulders of LXC technology have provided developers with a platform to run their applications and at the same time have empowered operations people with a tool that will allow them to deploy the same container on production servers or data centers. It tries to make the experience between a developer running an application, booting and testing an application and an operations person deploying that application seamless, because this is where all the friction lies in and purpose of DevOps is to break down those silos.
So the best approach is the cloud infrastructure providers should advocate an appropriate use of the VMs and LXC, as they are each suited to handle specific workloads and scenarios.
Abandoning VMs is not practical as of now. So both VMs and LXCs have their own individual existence and importance.
Install pip
Download get-pip. Remember to save it as "get-pip.py"
Now go to the download folder. Right click on get-pip.py then open with python.exe.
You can add system variable by
(by doing this you can use pip and easy_install without specifying path)
1 Clicking on Properties of My Computer
2 Then chose Advanced System Settings
3 Click on Advanced Tab
4 Click on Environment Variables
5 From System Variables >>> select variable path.
6 Click edit then add the following lines at the end of it
;c:\Python27;c:\Python27\Scripts
(please dont copy this, just go to your python directory and copy the paths similar to this)
NB:- you have to do this once only.

// My stored keys and values from the json object
HashMap<String,String> myKeyValues = new HashMap<String,String>();

Stack<String> key_path = new Stack<String>();

try{
key_path.push(json_key);
loadJson(json.getJSONObject(json_key));
}catch (JSONException e){
// Build the path to the key
String key = "";
for(String sub_key: key_path){
key += sub_key+".";
}
key = key.substring(0,key.length()-1);
System.out.println(key+": "+json.getString(json_key));

myKeyValues.put(key, json.getString(json_key));
}
}
if(key_path.size() > 0){
key_path.pop();

}
What you're trying to insert is not a date, I think, but a string. You need to use to_date()
function, like this:
insert into table t1 (id, date_field) values (1, to_date('20.06.2013', 'dd.mm.yyyy'));
Clearing Resharper's cache did not help in my case, tried suspend/restore, and also Repair Resharper, using latest download off JetBrains' website - neither of these helped. This is after I tried close/reopen VS, restart my machine, repeat, Build/Rebuild and combination thereof.
It's interesting that suspending Resharper seemed to solve the problem after the 2nd restart of VS, but it was back after I enabled Resharper <-- I tried to do this sequence 2-3 times to ensure the pattern.
Anyway, I was still having issues when I found this article:

If i understand your question, you just want to be able to access items in a data frame (or list) by row:
x = matrix( ceiling(9*runif(20)), nrow=5 )
colnames(x) = c("col1", "col2", "col3", "col4")
df = data.frame(x) # create a small data frame
df[1,] # get the first row
df[3,] # get the third row
df[nrow(df),] # get the last row
lf = as.list(df)
lf[[1]] # get first row
lf[[3]] # get third row
etc.

There is an interesting discussion here: http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/307d658a-f677-40f2-bdef-e6352b0bfe9e/ My understanding of this thread is that freeing small allocations are not reflected in Private Bytes or Working Set.
Long story short:
if I call
p=malloc(1000);
free(p);
then the Private Bytes reflect only the allocation, not the deallocation.
if I call
p=malloc(>512k);
free(p);
then the Private Bytes correctly reflect the allocation and the deallocation.

Must say I agree with that the most elegant solution to this is using boost::lexical_cast. You can then catch the bad_lexical_cast that might occure, and do something when it fails, instead of getting 0.0 which atof gives.
#include <boost/lexical_cast.hpp>
#include <string>
int main()
{
std::string str = "3.14";
double strVal;
try {
strVal = boost::lexical_cast<double>(str);
} catch(bad_lexical_cast&) {
//Do your errormagic
}
return 0;
}
Array
in JSON
are indexed array only, so the structure you're trying to get is not valid Json/Javascript.
PHP Associatives array are objects in JSON, so unless you don't need the index, you can't do such conversions.
If you want to get such structure you can do:
$indexedOnly = array();
foreach ($associative as $row) {
$indexedOnly[] = array_values($row);
}
json_encode($indexedOnly);
Will returns something like:
[
[0, "name1", "n1"],
[1, "name2", "n2"],
]
Imagine a counter with an initial value of 0
.
For every loop, increment the counter value by 1 using $counter = 0;
The final counter value returned by the loop will be the number of iterations of your for loop. Find the code below:
$counter = 0;
foreach ($Contents as $item) {
$counter++;
$item[number];// if there are 15 $item[number] in this foreach, I want get the value `: 15`
}
Try that.
Honestly, I hate all the solutions I've seen so far, and I'll tell you why: They just don't seem to ever align it right...so here's what I usually do:
I know what pixel values each div and their respective margins hold...so I do the following.
I'll create a wrapper div that has an absolute position and a left value of 50%...so this div now starts in the middle of the screen, and then I subtract half of all the content of the div's width...and I get BEAUTIFULLY scaling content...and I think this works across all browsers, too. Try it for yourself (this example assumes all content on your site is wrapped in a div tag that uses this wrapper class and all content in it is 200px in width):
.wrapper {
position: absolute;
left: 50%;
margin-left: -100px;
}
EDIT: I forgot to add...you may also want to set width: 0px; on this wrapper div for some browsers to not show the scrollbars, and then you may use absolute positioning for all inner divs.
This also works AMAZING for vertically aligning your content as well using top: 50% and margin-top. Cheers!
I had the same problem and seems like we haven't had an accurate solution. Hope this can help other people.
After take time exploring around, I finally found the answer. This is my code to get file attach with jQuery:
var attach_id = "id_of_attachment_file";
var size = $('#'+attach_id)[0].files[0].size;
alert(size);
This is just the example code for getting the file size. If you want do other stuffs, feel free to change the code to satisfy your needs.
In my case this error caused by wrong /etc/nsswitch.conf configuration on debian.
I've been replaced string
hosts: files myhostname mdns4_minimal [NOTFOUND=return] dns
with
hosts: files dns
and everything works right now.
You have to use the FormulaEvaluator, as shown here. This will return a value that is either the value present in the cell or the result of the formula if the cell contains such a formula :
FileInputStream fis = new FileInputStream("/somepath/test.xls");
Workbook wb = new HSSFWorkbook(fis); //or new XSSFWorkbook("/somepath/test.xls")
Sheet sheet = wb.getSheetAt(0);
FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();
// suppose your formula is in B3
CellReference cellReference = new CellReference("B3");
Row row = sheet.getRow(cellReference.getRow());
Cell cell = row.getCell(cellReference.getCol());
if (cell!=null) {
switch (evaluator.evaluateFormulaCell(cell)) {
case Cell.CELL_TYPE_BOOLEAN:
System.out.println(cell.getBooleanCellValue());
break;
case Cell.CELL_TYPE_NUMERIC:
System.out.println(cell.getNumericCellValue());
break;
case Cell.CELL_TYPE_STRING:
System.out.println(cell.getStringCellValue());
break;
case Cell.CELL_TYPE_BLANK:
break;
case Cell.CELL_TYPE_ERROR:
System.out.println(cell.getErrorCellValue());
break;
// CELL_TYPE_FORMULA will never occur
case Cell.CELL_TYPE_FORMULA:
break;
}
}
if you need the exact contant (ie the formla if the cell contains a formula), then this is shown here.
Edit : Added a few example to help you.
first you get the cell (just an example)
Row row = sheet.getRow(rowIndex+2);
Cell cell = row.getCell(1);
If you just want to set the value into the cell using the formula (without knowing the result) :
String formula ="ABS((1-E"+(rowIndex + 2)+"/D"+(rowIndex + 2)+")*100)";
cell.setCellFormula(formula);
cell.setCellStyle(this.valueRightAlignStyleLightBlueBackground);
if you want to change the message if there is an error in the cell, you have to change the formula to do so, something like
IF(ISERR(ABS((1-E3/D3)*100));"N/A"; ABS((1-E3/D3)*100))
(this formula check if the evaluation return an error and then display the string "N/A", or the evaluation if this is not an error).
if you want to get the value corresponding to the formula, then you have to use the evaluator.
Hope this help,
Guillaume

The answer is simpler than people are making it.
There's no technical advantage either way, and "x is not y" is what everybody else uses, which makes it the clear winner. It doesn't matter that it "looks more like English" or not; everyone uses it, which means every user of Python--even Chinese users, whose language Python looks nothing like--will understand it at a glance, where the slightly less common syntax will take a couple extra brain cycles to parse.
Don't be different just for the sake of being different, at least in this field.

Another possible fix:
For some reason, this work.
None of the above answers helped me, but I just found the solution.
For those who couldn't benefit from any of the above answers;
The issue was that I tried to build project with another Team.
I have 2 different teams as you see
I noticed that I did debug before with second team and xCode automatically created an App ID in second team's developer account.
I opened https://developer.apple.com/ for second account and removed auto-created APP ID
Then worked fine
Make sure you're not telling IIS to check and see if a file exists before serving it up. This one has bitten me a couple times. Do the following:
Open IIS manager. Right click on your MVC website and click properties. Open the Virtual Directory tab. Click the Configuration... button. Under Wildcard application maps, make sure you have a mapping to c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll
. MAKE SURE "Verify the file exists" IS NOT CHECKED!
Sure.
You need to compare 'installed packages' with 'desired packages'. That's very close to what I do with CRANberries as I need to compare 'stored known packages' with 'currently known packages' to determine new and/or updated packages.
So do something like
AP <- available.packages(contrib.url(repos[i,"url"])) # available t repos[i]
to get all known packages, simular call for currently installed packages and compare that to a given set of target packages.
.table-hover tbody tr:hover td {
background: aqua;
}
this is the best solution i can gice so far.it works out perfectly in such scena
Use FromResult Method
public async Task<string> GetString()
{
System.Threading.Thread.Sleep(5000);
return await Task.FromResult("Hello");
}
chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]
This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:
data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]
Outputs:
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]
There is no way to configure an exclusion to the proxy settings, but a colleague of mine had an create solution for that particular problem. He installed a local proxy server called cntlm. That server supports ntlm authentication and exclusions to the general proxy settings. A perfect match.
As far as I can tell Python, up through 2.5, only supports hexadecimal & octal literals. I did find some discussions about adding binary to future versions but nothing definite.
For me worked only adding the config
or ssh_config
file that was on the dir ~/.ssh/config
on my Linux system on the c:\Program Files\Git\etc\ssh\
directory on Windows.
In some git versions we need to edit the C:\Users\<username>\AppData\Local\Programs\Git\etc\ssh\ssh_config
file.
After that, I was able to use all the alias and settings that I normally used on my Linux connecting or pushing via SSH on the Git Bash.
This could be more helpfull....
$("element").prop("id", "modifiedId");
//for boolean
$("element").prop("disabled", true);
//also you can remove attribute
$('#someid').removeProp('disabled');
Just for the record, since SQL 2012 you can use FORMAT, as simple as:
SELECT FORMAT(GETDATE(), 'ddMMyyyy')
(op question is specific about SQL 2008)
I have the same problem. Mine is caused by a vmware installation. It is vmware worstation v8 on windows 7 and was a default installation.
Running netstat -aon | find ":80" | find "LISTENING" from cmd showed PID of the service causing the problem, this related to vmware. Going to services, I manually stopped all of the running vmware services (did not change their start up type, just a manual stop - I want them to work again after the next reboot) I could immediately test my webservice, glassfish 4 started as it should.
Hope it helps
RecyclerView was created as a ListView improvement, so yes, you can create an attached list with ListView control, but using RecyclerView is easier as it:
Reuses cells while scrolling up/down : this is possible with implementing View Holder in the ListView adapter, but it was an optional thing, while in the RecycleView it's the default way of writing adapter.
Decouples list from its container : so you can put list items easily at run time in the different containers (linearLayout, gridLayout) with setting LayoutManager.
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view); mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));
So, to conclude, RecyclerView is a more flexible control for handling "list data" that follows patterns of delegation of concerns and leaves for itself only one task - recycling items.
I had an issue where I was pushing to my remote repo from a local repo that didn't match up with history of remote. This is what worked for me.
I cloned my repo locally so I knew I was working with fresh copy of repo:
git clone Your_REPO_URL_HERE.git
Switch to the branch you are trying to get into the remote:
git checkout Your_BRANCH_NAME_HERE
Add the remote of the original:
git remote add upstream Your_REMOTE_REPO_URL_HERE.git
Do a git fetch and git pull:
git fetch --all
git pull upstream Your_BRANCH_NAME_HERE
If you have merge conflicts, resolve them with
git mergetool kdiff3
or other merge tool of your choice.
Once conflicts are resolved and saved. Commit and push changes.
Now go to the gitub.com repo of the original and attempt to create a pull request. You should have option to create pull request and not see the "Nothing to compare, branches are entirely different commit histories" Note: You may need to choose compare across forks for your pull request.
request.getSession(true)
and request.getSession()
both do the same thing, but if we use
request.getSession(false)
it will return null
if session object not created yet.
In case you want to pass multiple arguments you can use a tuple
price = 33.3
with open("Output.txt", "w") as text_file:
text_file.write("Purchase Amount: %s price %f" % (TotalAmount, price))
mysqldump --extended-insert=FALSE
Be aware that multiple inserts will be slower than one big insert.
Late to the party here, but if using VSCode, a quick way to do so is to open the command palette (CTRL / CMD + SHIFT + P) and type "Pop Stash", you'll be able to retrieve your stash by name without the need to use git CLI
And here is the non jQuery answer.
Fiddle: http://jsfiddle.net/J7m7m/7/
function changeText(value) {
document.getElementById('count').value = 500 * value;

Total <input type="text" id="count" value="1"/>
EDIT: It is very clear that this is a non-desired way as pointed out below (I had it coming). So in essence, this is how you would do it in plain old javascript. Most people would suggest you to use jQuery (other answer has the jQuery version) for good reason.
As commented by David Thomas, descendants of those child elements will (likely) inherit most of the styles assigned to those child elements.
You need to wrap your .myTestClass
inside an element and apply the styles to descendants by adding .wrapper *
descendant selector. Then, add .myTestClass > *
child selector to apply the style to the elements children, not its grand children. For example like this:
JSFiddle - DEMO
.wrapper * {_x000D_
color: blue;_x000D_
margin: 0 100px; /* Only for demo */_x000D_
}_x000D_
.myTestClass > * {_x000D_
color:red;_x000D_
margin: 0 20px;_x000D_
}
_x000D_
<div class="wrapper">_x000D_
<div class="myTestClass">Text 0_x000D_
<div>Text 1</div>_x000D_
<span>Text 1</span>_x000D_
<div>Text 1_x000D_
<p>Text 2</p>_x000D_
<div>Text 2</div>_x000D_
</div>_x000D_
<p>Text 1</p>_x000D_
</div>_x000D_
<div>Text 0</div>_x000D_
</div>
_x000D_
While there are IPv6 equivalents for the IPv4 address range, you can't convert all IPv6 addresses to IPv4 - there are more IPv6 addresses than there are IPv4 addresses.
The only sane way around this issue is to update your application to be able to understand and store IPv6 addresses.
@bogatron already gave the answer suggested by the matplotlib docs, which produces the right height, but it introduces a different problem. Now the width of the colorbar (as well as the space between colorbar and plot) changes with the width of the plot. In other words, the aspect ratio of the colorbar is not fixed anymore.
To get both the right height and a given aspect ratio, you have to dig a bit deeper into the mysterious axes_grid1
module.
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable, axes_size
import numpy as np
aspect = 20
pad_fraction = 0.5
ax = plt.gca()
im = ax.imshow(np.arange(200).reshape((20, 10)))
divider = make_axes_locatable(ax)
width = axes_size.AxesY(ax, aspect=1./aspect)
pad = axes_size.Fraction(pad_fraction, width)
cax = divider.append_axes("right", size=width, pad=pad)
plt.colorbar(im, cax=cax)
Note that this specifies the width of the colorbar w.r.t. the height of the plot (in contrast to the width of the figure, as it was before).
The spacing between colorbar and plot can now be specified as a fraction of the width of the colorbar, which is IMHO a much more meaningful number than a fraction of the figure width.
UPDATE:
I created an IPython notebook on the topic, where I packed the above code into an easily re-usable function:
import matplotlib.pyplot as plt
from mpl_toolkits import axes_grid1
def add_colorbar(im, aspect=20, pad_fraction=0.5, **kwargs):
"""Add a vertical color bar to an image plot."""
divider = axes_grid1.make_axes_locatable(im.axes)
width = axes_grid1.axes_size.AxesY(im.axes, aspect=1./aspect)
pad = axes_grid1.axes_size.Fraction(pad_fraction, width)
current_ax = plt.gca()
cax = divider.append_axes("right", size=width, pad=pad)
plt.sca(current_ax)
return im.axes.figure.colorbar(im, cax=cax, **kwargs)
It can be used like this:
im = plt.imshow(np.arange(200).reshape((20, 10)))
add_colorbar(im)
You can also put the JavaScript code in script tags, rather than a separate function. <script>//JS Code</script>
This way the code will get executes on Page Load.
if you get to use the q library https://github.com/kriskowal/q it has q.allSettled() method that can solve this problem you can handle every promise depending on its state either fullfiled or rejected so
existingPromiseChain = existingPromiseChain.then(function() {
var arrayOfPromises = state.routes.map(function(route){
return route.handler.promiseHandler();
});
return q.allSettled(arrayOfPromises)
});
existingPromiseChain = existingPromiseChain.then(function(arrayResolved) {
//so here you have all your promises the fulfilled and the rejected ones
// you can check the state of each promise
arrayResolved.forEach(function(item){
if(item.state === 'fulfilled'){ // 'rejected' for rejected promises
//do somthing
} else {
// do something else
}
})
// do stuff with my array of resolved promises, eventually ending with a res.send();
});
For someone who doesn’t need the BuildConfig information for application's UI, however wants to use this information for setting a CI job configuration or others, like me:
There is an automatically generated file, BuildConfig.java, under your project directory as long as you build your project successfully.
{WORKSPACE}/build/generated/source/buildConfig/{debug|release}/{PACKAGE}/BuildConfig.java
/**
* Automatically generated file. DO NOT MODIFY
*/
package com.XXX.Project;
public final class BuildConfig {
public static final boolean DEBUG = Boolean.parseBoolean("true");
public static final String APPLICATION_ID = "com.XXX.Project";
public static final String BUILD_TYPE = "debug";
public static final String FLAVOR = "";
public static final int VERSION_CODE = 1;
public static final String VERSION_NAME = "1.0.0";
}
Split information you need by a Python script or other tools. Here’s an example:
import subprocess
# Find your BuildConfig.java
_BuildConfig = subprocess.check_output('find {WORKSPACE} -name BuildConfig.java', shell=True).rstrip()
# Get the version name
_Android_version = subprocess.check_output('grep -n "VERSION_NAME" ' + _BuildConfig, shell=True).split('"')[1]
print('Android version: ’ + _Android_version)
According to Oracle's Java Documentation:
private static final Pattern NUMBER_PATTERN = Pattern.compile(
"[\\x00-\\x20]*[+-]?(NaN|Infinity|((((\\p{Digit}+)(\\.)?((\\p{Digit}+)?)" +
"([eE][+-]?(\\p{Digit}+))?)|(\\.((\\p{Digit}+))([eE][+-]?(\\p{Digit}+))?)|" +
"(((0[xX](\\p{XDigit}+)(\\.)?)|(0[xX](\\p{XDigit}+)?(\\.)(\\p{XDigit}+)))" +
"[pP][+-]?(\\p{Digit}+)))[fFdD]?))[\\x00-\\x20]*");
boolean isNumber(String s){
return NUMBER_PATTERN.matcher(s).matches()
}
If you are fine using a graphical tool this works very well:
gitk <file>
gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!
I would just use a Union
In your second query add the extra column name and add a ''
in all the corresponding locations in the other queries
Example
//reverse order to get the column names
select top 10 personId, '' from Telephone//No Column name assigned
Union
select top 10 personId, loanId from loan
To subtract timevals:
gettimeofday(&t0, 0);
/* ... */
gettimeofday(&t1, 0);
long elapsed = (t1.tv_sec-t0.tv_sec)*1000000 + t1.tv_usec-t0.tv_usec;
This is assuming you'll be working with intervals shorter than ~2000 seconds, at which point the arithmetic may overflow depending on the types used. If you need to work with longer intervals just change the last line to:
long long elapsed = (t1.tv_sec-t0.tv_sec)*1000000LL + t1.tv_usec-t0.tv_usec;
Environment.NewLine should be used as Dan Rigby said but there is one problem with the String.Empty. It will remain always empty no matter if it is read before or after it reads. I had a problem in my project yesterday with that. I removed it and it worked the way it was supposed to. It's better to declare the variable and then call it when it's needed. String.Empty will always keep it empty unless the variable needs to be initialized which only then should you use String.Empty. Thought I would throw this tid-bit out for everyone as I've experienced it.
For this you can simply use the redirect
function that is included in flask
from flask import Flask, redirect
app = Flask(__name__)
@app.route('/')
def hello():
return redirect("https://www.exampleURL.com", code = 302)
if __name__ == "__main__":
app.run()
Another useful tip(as you're new to flask), is to add app.debug = True
after initializing the flask object as the debugger output helps a lot while figuring out what's wrong.
To enable the query log in MAC Machine:
Open the following file:
vi /private/etc/my.cnf
Set the query log url under 'mysqld' section as follows:
[mysqld]
general_log_file=/Users/kumanan/Documents/mysql_query.log
Few machine’s are not logging query properly, So that case you can enable it from MySQL console
mysql> SET global general_log = 1;
In order for a bot to send a message, you need <client>.send()
, the client
is where the bot will send a message to(A channel, everywhere in the server, or a PM). Since you want the bot to PM a certain user, you can use message.author
as your client
. (you can replace author
as mentioned user in a message or something, etc)
Hence, the answer is: message.author.send("Your message here.")
I recommend looking up the Discord.js documentation about a certain object's properties whenever you get stuck, you might find a particular function that may serve as your solution.
function palindrome(str) {
var testString = str.toLowerCase();
var expression = /[a-z0-9\^s]/gi;
if (testString.match(expression).reverse().join("") == testString.match(expression).join("")) {
return true;
} else {
return false;
}
}
I solved the problem by using the index to read the string and checking one by one. Reading using the name still gives the same error.
I have the problem when I develop a C# window application, I did not have the problem in my asp.net application. There must be something in the setting which is not right.
easy!
if option == str(1):
numberA = int(raw_input("enter first number. "))
numberB= int(raw_input("enter second number. "))
print " "
print addition(numberA, numberB)
etc etc etc
If you want to check if a string has a numeric value, use this code:
$a = "44.4"
$b = "ad"
$rtn = ""
[double]::TryParse($a,[ref]$rtn)
[double]::TryParse($b,[ref]$rtn)

If you are looking for a range of columns, you can try this:
df.iloc[7:] = df.iloc[7:].astype(float)
The examples above will convert type to be float, for all the columns begin with the 7th to the end. You of course can use different type or different range.
I think this is useful when you have a big range of columns to convert and a lot of rows. It doesn't make you go over each row by yourself - I believe numpy do it more efficiently.
This is useful only if you know that all the required columns contain numbers only - it will not change "bad values" (like string) to be NaN for you.
The --no-ff
option is useful when you want to have a clear notion of your feature branch. So even if in the meantime no commits were made, FF is possible - you still want sometimes to have each commit in the mainline correspond to one feature. So you treat a feature branch with a bunch of commits as a single unit, and merge them as a single unit. It is clear from your history when you do feature branch merging with --no-ff
.
If you do not care about such thing - you could probably get away with FF whenever it is possible. Thus you will have more svn-like feeling of workflow.
For example, the author of this article thinks that --no-ff
option should be default and his reasoning is close to that I outlined above:
Consider the situation where a series of minor commits on the "feature" branch collectively make up one new feature: If you just do "git merge feature_branch" without --no-ff
, "it is impossible to see from the Git history which of the commit objects together have implemented a feature—you would have to manually read all the log messages. Reverting a whole feature (i.e. a group of commits), is a true headache [if --no-ff
is not used], whereas it is easily done if the --no-ff
flag was used [because it's just one commit]."
I have found that creating a var to hold the WebElement
and the call the sendKeys()
works for me.
WebElement speedCurrentCell = driver.findElement(By.id("Speed_current"));
speedCurrentCell.sendKeys("1300");
I've added a "Connected Service" to our project by Visual Studio which generated a default method to create Client.
var client = new MyWebService.Client(MyWebService.Client.EndpointConfiguration.MyPort, _endpointUrl);
This constructor inherits ClientBase and behind the scene is creating Binding by using its own method Client.GetBindingForEndpoint(endpointConfiguration):
public Client(EndpointConfiguration endpointConfiguration, string remoteAddress) :
base(Client.GetBindingForEndpoint(endpointConfiguration),
new System.ServiceModel.EndpointAddress(remoteAddress))
This method has different settings for https service and http service. When you want get data from http, you should use TransportCredentialOnly:
System.ServiceModel.BasicHttpBinding result = new System.ServiceModel.BasicHttpBinding();
result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportCredentialOnly;
For https you should use Transport:
result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;
SJF are two type - i) non preemptive SJF ii)pre-emptive SJF
I have re-arranged the processes according to Arrival time. here is the non preemptive SJF
A.T= Arrival Time
B.T= Burst Time
C.T= Completion Time
T.T = Turn around Time = C.T - A.T
W.T = Waiting Time = T.T - B.T
Here is the preemptive SJF Note: each process will preempt at time a new process arrives.Then it will compare the burst times and will allocate the process which have shortest burst time. But if two process have same burst time then the process which came first that will be allocated first just like FCFS.
You may put an inner div in the container that is enough wide to hold all the floated divs.

This code:
from scipy.stats import linregress
linregress(x,y) #x and y are arrays or lists.
gives out a list with the following:
slope : float
slope of the regression line
intercept : float
intercept of the regression line
r-value : float
correlation coefficient
p-value : float
two-sided p-value for a hypothesis test whose null hypothesis is that the slope is zero
stderr : float
Standard error of the estimate
mins = minutes + 1
should be
minutes = minutes + 1
Also,
minutes = 0
needs to be outside of the while loop.
Use git ls-files
to checkout deleted(-d) or modified(-m) files.
git checkout $(git ls-files -d)
see How can I restore only the modified files on a git checkout?
There is no such thing as an "epoch" in a specific timezone. The epoch is well-defined as a specific moment in time, so if you change the timezone, the time itself changes as well. Specifically, this time is Jan 1 1970 00:00:00 UTC
. So time.time()
returns the number of seconds since the epoch.
If you want more general information about various methods of representing numbers including Two's Complement have a look at:
Two's Complement and Signed Number Representation on Wikipedia
using (WebClient client = new WebClient())
{
byte[] response =
client.UploadValues("http://dork.com/service", new NameValueCollection()
{
{ "home", "Cosby" },
{ "favorite+flavor", "flies" }
});
string result = System.Text.Encoding.UTF8.GetString(response);
}
You will need these includes:
using System;
using System.Collections.Specialized;
using System.Net;
If you're insistent on using a static method/class:
public static class Http
{
public static byte[] Post(string uri, NameValueCollection pairs)
{
byte[] response = null;
using (WebClient client = new WebClient())
{
response = client.UploadValues(uri, pairs);
}
return response;
}
}
Then simply:
var response = Http.Post("http://dork.com/service", new NameValueCollection() {
{ "home", "Cosby" },
{ "favorite+flavor", "flies" }
});
I got the same error when xampp was installed on windows 10.
www.example.com:443:0 server certificate does NOT include an ID which matches the server name
So I opened httpd-ssl.conf
file in xampp folder and changed the following line
ServerName www.example.com:443
To
ServerName localhost
And the problem was fixed.
If I understood you right, you mean that if you have a function 'func', you want to check for each item in list if func(item) returns true; if you get true for all, then do something.
You can use 'all'.
For example: I want to get all prime numbers in range 0-10 in a list:
from math import sqrt
primes = [x for x in range(10) if x > 2 and all(x % i !=0 for i in range(2, int(sqrt(x)) + 1))]
pathlib.Path.rglob
Use pathlib.Path.rglob
from the the pathlib
module, which was introduced in Python 3.5.
from pathlib import Path
for path in Path('src').rglob('*.c'):
print(path.name)
If you don't want to use pathlib, use can use glob.glob('**/*.c')
, but don't forget to pass in the recursive
keyword parameter and it will use inordinate amount of time on large directories.
For cases where matching files beginning with a dot (.
); like files in the current directory or hidden files on Unix based system, use the os.walk
solution below.
os.walk
For older Python versions, use os.walk
to recursively walk a directory and fnmatch.filter
to match against a simple expression:
import fnmatch
import os
matches = []
for root, dirnames, filenames in os.walk('src'):
for filename in fnmatch.filter(filenames, '*.c'):
matches.append(os.path.join(root, filename))
jQuery.fn.make_me_red = function() {
return this.each(function() {
this.style.color = 'red';
});
};
$('a').make_me_red() // - instead of this you can use $(this).make_me_red() instead for better readability.

You want to ask is "what is the difference between a mutable and a non-mutable array or dictionary." Many times there different terms are used to describe things that you already know about. In this case, you can replace the term "mutable" with "dynamic." So, a mutuable dictionary or array is one that is "dynamic" and can change at runtime, whereas a non-mutable dictionary or array is one that is "static" and defined in your code and does not change at runtime (in other words, you will not be adding, deleting or possibly sorting the elements.)
As to how it is done, you are asking us to repeat the documentation here. All you need to do is to search in sample code and the Xcode documentation to see exactly how it is done. But the mutable thing threw me too when I was first learning, so I'll give you that one!
I know this is an old post but I thought I might add a thought for people who come across a similar problem. I'm assuming that you are using ASP.NET MVC since you mentioned site.css.
Check your Bundles.config file to see if you have BundleTable.EnableOptimizations = true
; If you don't, then it can be your problem since this allows the program to be bundles and "minified". Depending on if you run in debug mode or not this could have an effect.
I am also faced the same issue
use this code:
// notice string() call
String resStr = response.body().string();
JSONObject json = new JSONObject(resStr);
it definitely works
Haven't tested it, but that should alert the blobs data url:
var blob = event.clipboardData.items[0].getAsFile(),
form = new FormData(),
request = new XMLHttpRequest();
var reader = new FileReader();
reader.onload = function(event) {
alert(event.target.result); // <-- data url
};
reader.readAsDataURL(blob);
I'll throw mine in the mix:

this evaluates the if statement once and adds no watch listener BUT you can add an additional attribute to the element that has the set-if called wait-for="somedata.prop" and it will wait for that data or property to be set before evaluating the if statement once. that additional attribute can be very handy if you're waiting for data from an XHR request.
angular.module('setIf',[]).directive('setIf',function () {
return {
transclude: 'element',
priority: 1000,
terminal: true,
restrict: 'A',
compile: function (element, attr, linker) {
return function (scope, iterStartElement, attr) {
if(attr.waitFor) {
var wait = scope.$watch(attr.waitFor,function(nv,ov){
if(nv) {
build();
wait();
}
});
} else {
build();
}
function build() {
iterStartElement[0].doNotMove = true;
var expression = attr.setIf;
var value = scope.$eval(expression);
if (value) {
linker(scope, function (clone) {
iterStartElement.after(clone);
clone.removeAttr('set-if');
clone.removeAttr('wait-for');
});
}
}
};
}
};
});
This is a known issue in Chrome and resolved in latest versions. Please refer https://bugs.chromium.org/p/chromium/issues/detail?id=942440 for more details.
You can use $(function(){ // code });
which is executed when the document is ready to execute the code inside that block.
$(function(){
$('#clicker').click(function(){
alert('hey');
$('.hide_div').hide();
});
});
If you installed rspec as a plugin rather than as a gem, then you won't have the spec
executable.
At any rate, All you need to do is run the file using ruby. The rspec code is clever enough to run the tests for you.
eg:
ruby myclass_spec.rb
The other answers answer the question adequately, but your example looks like the second command depends on the first one being exiting successfully. You may want to try a short-circuit evaluation in your alias:
alias lock='gnome-screensaver && gnome-screensaver-command --lock'
Now the second command will not even be attempted unless the first one is successful. A better description of short-circuit evaluation is described in this SO question.
Let's say you have 'black box' application with some class named BlackBoxClass
that has method doSomething();
.
Further, you have observer or listener named onResponse(String resp)
that will be called by BlackBoxClass
after unknown time.
The flow is simple:
private String mResponse = null;
...
BlackBoxClass bbc = new BlackBoxClass();
bbc.doSomething();
...
@override
public void onResponse(String resp){
mResponse = resp;
}
Lets say we don't know what is going on with BlackBoxClass
and when we should get answer but you don't want to continue your code till you get answer or in other word get onResponse
call. Here enters 'Synchronize helper':
public class SyncronizeObj {
public void doWait(long l){
synchronized(this){
try {
this.wait(l);
} catch(InterruptedException e) {
}
}
}
public void doNotify() {
synchronized(this) {
this.notify();
}
}
public void doWait() {
synchronized(this){
try {
this.wait();
} catch(InterruptedException e) {
}
}
}
}
Now we can implement what we want:
public class Demo {
private String mResponse = null;
...
SyncronizeObj sync = new SyncronizeObj();
public void impl(){
BlackBoxClass bbc = new BlackBoxClass();
bbc.doSomething();
if(mResponse == null){
sync.doWait();
}
/** at this momoent you sure that you got response from BlackBoxClass because
onResponse method released your 'wait'. In other cases if you don't want wait too
long (for example wait data from socket) you can use doWait(time)
*/
...
}
@override
public void onResponse(String resp){
mResponse = resp;
sync.doNotify();
}
}
What about an answer for the question related to a workflow like this?
merge --squash
after the PR, but the team thought that would slow down the process.)I haven't seen a workflow like that on this page. (That may be my eyes.) If I understand rebase
correctly, multiple merges would require multiple conflict resolutions. I do NOT want even to think about that!
So, this seems to work for us.
git pull master
git checkout -b new-branch
git checkout -b new-branch-temp
git checkout new-branch
git merge --squash new-branch-temp
// puts all changes in stagegit commit 'one message to rule them all'
git push
export const authHandler = (config) => {
const authRegex = /^\/apiregex/;
if (!authRegex.test(config.url)) {
return store.fetchToken().then((token) => {
Object.assign(config.headers.common, { Authorization: `Bearer ${token}` });
return Promise.resolve(config);
});
}
return Promise.resolve(config);
};
axios.interceptors.request.use(authHandler);
Ran into some gotchas when trying to implement something similar and based on these answers this is what I came up with. The problems I was experiencing were:
You need to do a forceful push after rebasing against master
If you're not explicitly using an encryption library, or rolling your own encryption code, then I think the answer is "no"
I recently run into this problem, when trying to count using case when
, and found that changing the order of the which
and count
statements fixes the problem:
SELECT date(dateday) as pick_day,
COUNT(CASE WHEN (apples = 'TRUE' OR oranges 'TRUE') THEN fruit END) AS fruit_counter
FROM pickings
GROUP BY 1
Instead of using - in the latter, where I got errors that apples and oranges should appear in aggregate functions
CASE WHEN ((apples = 'TRUE' OR oranges 'TRUE') THEN COUNT(*) END) END AS fruit_counter
Return as a tuple, e.g.
def foo (a):
x=a
y=a*2
return (x,y)
