In general, one doesn't expand out log(a + b)
; you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:
log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)
(In fact, this identity is often used when implementing log
in math libraries).
The dll
is missing in the published (deployed environment). That is the reason why it is working in the local i.e. Visual Studio but not in the Azure Website Environment.
Just do Copy Local = true
in the properties for the assembly(System.Web.Http.WebHost) and then do a redeploy, it should work fine.
If you get the similar error i.e. some other assembly missing, then make that assembly to copylocal=true and redeploy, repeat this iteratively - if you are unsure of its dependencies.
You can reference Microsoft.VisualBasic.dll
.
Then using the code below.
Microsoft.VisualBasic.Interaction.InputBox("Question?","Title","Default Text");
Alternatively, by adding a using
directive allowing for a shorter syntax in your code (which I'd personally prefer).
using Microsoft.VisualBasic;
...
Interaction.InputBox("Question?","Title","Default Text");
Or you can do what Pranay Rana suggests, that's what I would've done too...
foreach (DataGridViewRow row in dataGridView1.Rows)
{
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
String header = dataGridView1.Columns[i].HeaderText;
//String cellText = row.Cells[i].Text;
DataGridViewColumn column = dataGridView1.Columns[i]; // column[1] selects the required column
column.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells; // sets the AutoSizeMode of column defined in previous line
int colWidth = column.Width; // store columns width after auto resize
colWidth += 50; // add 30 pixels to what 'colWidth' already is
this.dataGridView1.Columns[i].Width = colWidth; // set the columns width to the value stored in 'colWidth'
}
}
List<T>.Add
adds a single element. Instead, use List<T>.AddRange
to add multiple values.
Additionally, List<T>.AddRange
takes an IEnumerable<T>
, so you don't need to convert tripDetails
into a List<TripDetails>
, you can pass it directly, e.g.:
tripDetailsCollection.AddRange(tripDetails);
With Log4j2, this can be achieved using the following utility method added to your code.
private static void setLogLevel() {
if (Boolean.getBoolean("log4j.debug")) {
Configurator.setLevel(System.getProperty("log4j.logger"), Level.DEBUG);
}
}
You need these imports
import org.apache.logging.log4j.Level;
import org.apache.logging.log4j.core.config.Configurator;
Now invoke the setLogLevel
method in your main() or whereever appropriate and pass command line params -Dlog4j.logger=com.mypackage.Thingie
and -Dlog4j.debug=true
.
You should look into Java's interfaces. A quick Google search revealed this page, which looks pretty good.
I like to think of an interface
as a "promise" of sorts: Any class that implements it has certain behavior that can be expected of it, and therefore you can put an instance of an implementing class into an interface-type reference.
A simple example is the java.lang.Comparable
interface. By implementing all methods in this interface in your own class, you are claiming that your objects are "comparable" to one another, and can be partially ordered.
Implementing an interface requires two steps:
Interface java.lang.Comparable
has just one method in it, public int compareTo(Object other)
. So you need to provide that method.
Here's an example. Given this class RationalNumber
:
public class RationalNumber
{
public int numerator;
public int denominator;
public RationalNumber(int num, int den)
{
this.numerator = num;
this.denominator = den;
}
}
(Note: It's generally bad practice in Java to have public fields, but I am intending this to be a very simple plain-old-data type so I don't care about public fields!)
If I want to be able to compare two RationalNumber
instances (for sorting purposes, maybe?), I can do that by implementing the java.lang.Comparable
interface. In order to do that, two things need to be done: provide a definition for compareTo
and declare that the interface is implemented.
Here's how the fleshed-out class might look:
public class RationalNumber implements java.lang.Comparable
{
public int numerator;
public int denominator;
public RationalNumber(int num, int den)
{
this.numerator = num;
this.denominator = den;
}
public int compareTo(Object other)
{
if (other == null || !(other instanceof RationalNumber))
{
return -1; // Put this object before non-RationalNumber objects
}
RationalNumber r = (RationalNumber)other;
// Do the calculations by cross-multiplying. This isn't really important to
// the answer, but the point is we're comparing the two rational numbers.
// And no, I don't care if it's mathematically inaccurate.
int myTotal = this.numerator * other.denominator;
int theirTotal = other.numerator * this.denominator;
if (myTotal < theirTotal) return -1;
if (myTotal > theirTotal) return 1;
return 0;
}
}
You're probably thinking, what was the point of all this? The answer is when you look at methods like this: sorting algorithms that just expect "some kind of comparable object". (Note the requirement that all objects must implement java.lang.Comparable
!) That method can take lists of ANY kind of comparable objects, be they String
s or Integer
s or RationalNumber
s.
NOTE: I'm using practices from Java 1.4 in this answer. java.lang.Comparable
is now a generic interface, but I don't have time to explain generics.
It's case-sensitive, just make sure created branch and push to branch both are in same capital.
Example:
git checkout -b "TASK-135-hello-world"
WRONG way of doing:
git push origin task-135-hello-world #FATAL: task-135-hello-world cannot be resolved to branch
CORRECT way of doing:
git push origin TASK-135-hello-world
I used some jquery to solve this
$('html').css({
'overflow-y': 'hidden'
});
$(document).ready(function(){
$(window).load(function() {
$('html').css({
'overflow-y': ''
});
});
});
Use the namespace System.Net.Mail. Here is a link to the MSDN page
You can send emails using SmtpClient class.
I paraphrased the code sample, so checkout MSDNfor details.
MailMessage message = new MailMessage(
"[email protected]",
"[email protected]",
"Subject goes here",
"Body goes here");
SmtpClient client = new SmtpClient(server);
client.Send(message);
The best way to send many emails would be to put something like this in forloop and send away!

Write bytes and Create the file if not exists:
f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()
wb
means open the file in write binary

your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if
as a top-level step in declarative, so you need to wrap it in a script
step. here's a working declarative version:
pipeline {
agent any
stages {
stage('test') {
steps {
sh 'echo hello'
}
}
stage('test1') {
steps {
sh 'echo $TEST'
}
}
stage('test3') {
steps {
script {
if (env.BRANCH_NAME == 'master') {
echo 'I only execute on the master branch'
} else {
echo 'I execute elsewhere'
}
}
}
}
}
}
you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!

/*#{#pageable}*/
""")
public Page<Entity> findByNamespaceContainsAndNameContainsAndRawStateContainsMostRecentVersion(@Param("namespace")String namespace, @Param("name")String name, @Param("state")String state, Pageable pageable)
The key here was to use: /*#{#pageable}*/
It allows me to do sorting and pagination. You can test it by using something like this: http://localhost:8080/api/v1/entities/search/namespaceAndNameAndRawStateContainsMostRecentVersion?namespace=&name=&state=published&page=0&size=3&sort=name,desc
Watch out for this issue: Spring Pageable does not translate @Column name
The default behavior is:
If the parameter is a primitive type (int
, bool
, double
, ...), Web API tries to get the value from the URI of the HTTP request.
For complex types (your own object, for example: Person
), Web API tries to read the value from the body of the HTTP request.
So, if you have:
...then you don't have to add any attributes (neither [FromBody]
nor [FromUri]
).
But, if you have a primitive type in the body, then you have to add [FromBody]
in front of your primitive type parameter in your WebAPI controller method. (Because, by default, WebAPI is looking for primitive types in the URI of the HTTP request.)
Or, if you have a complex type in your URI, then you must add [FromUri]
. (Because, by default, WebAPI is looking for complex types in the body of the HTTP request by default.)
Primitive types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post([FromBody]int id)
{
}
// api/users/id
public HttpResponseMessage Post(int id)
{
}
}
Complex types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post(User user)
{
}
// api/users/user
public HttpResponseMessage Post([FromUri]User user)
{
}
}
This works as long as you send only one parameter in your HTTP request. When sending multiple, you need to create a custom model which has all your parameters like this:
public class MyModel
{
public string MyProperty { get; set; }
public string MyProperty2 { get; set; }
}
[Route("search")]
[HttpPost]
public async Task<dynamic> Search([FromBody] MyModel model)
{
// model.MyProperty;
// model.MyProperty2;
}
From Microsoft's documentation for parameter binding in ASP.NET Web API:
When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object). At most one parameter is allowed to read from the message body.
This should work:
public HttpResponseMessage Post([FromBody] string name) { ... }
This will not work:
// Caution: This won't work! public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }
The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.
I got here searching for this error:
No Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator
Nothing to do with Retrofit but if you are using Jackson this error got solved by adding a default constructor to the class throwing the error. More here: https://www.baeldung.com/jackson-exception

I have been using Django for over a year now, and am very impressed with how it manages to combine modularity, scalability and speed of development. Like with any technology, it comes with a learning curve. However, this learning curve is made a lot less steep by the excellent documentation from the Django community. Django has been able to handle everything I have thrown at it really well. It looks like it will be able to scale well into the future.
BidRodeo Penny Auctions is a moderately sized Django powered website. It is a very dynamic website and does handle a good number of page views a day.

There's a section on Bringing Up a Popup Menu in the How to Use Menus article of The Java Tutorials which explains how to use the JPopupMenu
class.
The example code in the tutorial shows how to add MouseListener
s to the components which should display a pop-up menu, and displays the menu accordingly.
(The method you describe is fairly similar to the way the tutorial presents the way to show a pop-up menu on a component.)
The Array prototype's reverse method modifies the array and returns a reference to it, which means you can do this:
var sortedAsc = _.sortBy(collection, 'propertyName');
var sortedDesc = _.sortBy(collection, 'propertyName').reverse();
Also, the underscore documentation reads:
In addition, the Array prototype's methods are proxied through the chained Underscore object, so you can slip a
reverse
or apush
into your chain, and continue to modify the array.
which means you can also use .reverse()
while chaining:
var sortedDescAndFiltered = _.chain(collection)
.sortBy('propertyName')
.reverse()
.filter(_.property('isGood'))
.value();

you just make a list of lists like so:
List<List<string>> results = new List<List<string>>();
and then it's just a matter of using the functionality you want
results.Add(new List<string>()); //adds a new list to your list of lists
results[0].Add("this is a string"); //adds a string to the first list
results[0][0]; //gets the first string in your first list
What are non-recursive mutexes good for?
They are absolutely good when you have to make sure the mutex is unlocked before doing something. This is because pthread_mutex_unlock
can guarantee that the mutex is unlocked only if it is non-recursive.
pthread_mutex_t g_mutex;
void foo()
{
pthread_mutex_lock(&g_mutex);
// Do something.
pthread_mutex_unlock(&g_mutex);
bar();
}
If g_mutex
is non-recursive, the code above is guaranteed to call bar()
with the mutex unlocked.
Thus eliminating the possibility of a deadlock in case bar()
happens to be an unknown external function which may well do something that may result in another thread trying to acquire the same mutex. Such scenarios are not uncommon in applications built on thread pools, and in distributed applications, where an interprocess call may spawn a new thread without the client programmer even realising that. In all such scenarios it's best to invoke the said external functions only after the lock is released.
If g_mutex
was recursive, there would be simply no way to make sure it is unlocked before making a call.

Oracle JDBC drivers and other companion Jars are available on Central Maven. We suggest to use the official supported Oracle JDBC versions from 11.2.0.4, 12.2.0.2, 18.3.0.0, 19.3.0.0, 19.6.0.0, and 19.7.0.0. These are available on Central Maven Repository. Refer to Maven Central Guide for more details.
It is recommended to use the latest version. Check out FAQ for JDK compatibility.
Just pointing out that it is use of parentheses that invokes auto-concatenation. That's fine if you happen to already be using them in the statement. Otherwise, I would just use '\' rather than inserting parentheses (which is what most IDEs do for you automatically). The indent should align the string continuation so it is PEP8 compliant. E.g.:
my_string = "The quick brown dog " \
"jumped over the lazy fox"
Basically, you want to loop through each direct descendent of the old-parent node, and move it to the new parent. Any children of a direct descendent will get moved with it.

while (oldParent.childNodes.length > 0) {
newParent.appendChild(oldParent.childNodes[0]);

Depending on the hibernate flush mode that you are using (AUTO
is the default) save
may or may not write your changes to the DB straight away. When you call saveAndFlush
you are enforcing the synchronization of your model state with the DB.
If you use flush mode AUTO and you are using your application to first save and then select the data again, you will not see a difference in bahvior between save()
and saveAndFlush()
because the select triggers a flush first. See the documention.

Open the HTML Form in your Browser, Input some data & submit it!
Submit the form. You should see a confirmation that it was sent:
Open the inbox for the email address you set (above)
Everything about this is customisable, you can easily style/theme the form with your favourite CSS Library and Store the submitted data in a Google Spreadsheet for quick analysis.

The core problem is what you define line and whether end-on-line character sequence is part of the line or not. UNIX-based editors (such as VIM) or tools (such as Git) use EOL character sequence as line terminator, therefore it's a part of the line. It's similar to use of semicolon (;) in C and Pascal. In C semicolon terminates statements, in Pascal it separates them.

Below is the link which guide in parsing JSON string in android.
http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE
Also according to your json string code snippet must be something like this:-
JSONObject mainObject = new JSONObject(yourstring);
JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");
JSONString url = universityObject.getString("url");
Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)
Same for other object.
The value returned by
hashCode()
is the object's hash code, which is the object's memory address in hexadecimal.By definition, if two objects are equal, their hash code must also be equal. If you override the
equals()
method, you change the way two objects are equated and Object's implementation ofhashCode()
is no longer valid. Therefore, if you override the equals() method, you must also override thehashCode()
method as well.
This answer is from the java SE 8 official tutorial documentation
Nullable types did not come in until 2.0.
If nullable types had been made in the beginning of the language then string would have been non-nullable and string? would have been nullable. But they could not do this du to backward compatibility.
A lot of people talk about ref-type or not ref type, but string is an out of the ordinary class and solutions would have been found to make it possible.
Because the people who created Java wanted boolean to mean unambiguously true or false, not 1 or 0.
There's no consensus among languages about how 1 and 0 convert to booleans. C uses any nonzero value to mean true and 0 to mean false, but some UNIX shells do the opposite. Using ints weakens type-checking, because the compiler can't guard against cases where the int value passed in isn't something that should be used in a boolean context.
This only works in Xcode 7

The "Encoding:" combo box will tell you specifically which encoding is currently being used for the file. It has a lot more text encodings listed in there than Notepad does, so it's useful when dealing with various files from around the world and whatever else.
Just like Notepad, you can also change the encoding from the list of options there, and then saving the file after hitting "OK". You can also select the encoding you want through the "Save with Encoding..." option in the Save As dialog (by clicking the arrow next to the Save button).
In my case I just needed to remove Homebrew's executable using:
sudo rm -f `which brew`
Then reinstall Homebrew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
In the most shared hosts you can't set it.
On a VPS or dedicated server, you can set it, but everything has its price.
On shared hosts, in general you receive a Linux account, something such as /home/(your username)/, and the equivalent of /var/www/html turns to /home/(your username)/public_html/ (or something similar, such as /home/(your username)/www)
If you're accessing your account via FTP, you automatically has accessing the your */home/(your username)/ folder, just find the www or public_html and put your site in it.
If you're using absolute path in the code, bad news, you need to refactor it to use relative paths in the code, at least in a shared host.
This should do it:
for (var i = 0; i < bank_holidays.length; i++) {
if (bank_holidays[i] === '06/04/2012') {
alert('LOL');
}
}
Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.
To solve your requirement, here is the working solution -
First create your ViewModels in following way. PersonModel can have list of RoleModels.
public class PersonModel
{
public List<RoleModel> Roles { get; set; }
public string Name { get; set; }
}
public class RoleModel
{
public string RoleName { get; set;}
public string Description { get; set;}
}
Then have a index action which will be serving basic index view -
public ActionResult Index()
{
return View();
}
Index view will be having following JQuery AJAX POST operation -
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
$(function () {
$('#click1').click(function (e) {
var jsonObject = {
"Name" : "Rami",
"Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
};
$.ajax({
url: "@Url.Action("AddUser")",
type: "POST",
data: JSON.stringify(jsonObject),
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (response) {
alert(response.responseText);
},
success: function (response) {
alert(response);
}
});
});
});
</script>
<input type="button" value="click1" id="click1" />
Index action posts to AddUser action -
[HttpPost]
public ActionResult AddUser(PersonModel model)
{
if (model != null)
{
return Json("Success");
}
else
{
return Json("An Error Has occoured");
}
}
So now when the post happens you can get all the posted data in the model parameter of action.
Update:
For asp.net core, to get JSON data as your action parameter you should add the [FromBody]
attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController]
attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)
(something else)
should be a.Country
if Country
is nullable then make(something else)
be a.Country OR a.Country is NULL
This was what I did to solve my related problem

See here if you want to grant a Facebook App permanent access to a page (even when you / the app owner are logged out):

If you would like to output array within string using puts
, you will get the same result as if you were using print
:
puts "#{[0, 1, nil]}":
[0, 1, nil]
But if not withing a quoted string then yes. The only difference is between new line when we use puts
.
you can configure the coverage exclusion in the sonar properties, outside of the configuration of the jacoco plugin:
...
<properties>
....
<sonar.exclusions>
**/generated/**/*,
**/model/**/*
</sonar.exclusions>
<sonar.test.exclusions>
src/test/**/*
</sonar.test.exclusions>
....
<sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>
<sonar.jacoco.reportPath>${project.basedir}/../target/jacoco.exec</sonar.jacoco.reportPath>
<sonar.coverage.exclusions>
**/generated/**/*,
**/model/**/*
</sonar.coverage.exclusions>
<jacoco.version>0.7.5.201505241946</jacoco.version>
....
</properties>
....
and remember to remove the exclusion settings from the plugin
Are you sure that you want "055" as opposed to "55"? Some programs interpret a leading zero as meaning octal, so that it would read 055 as (decimal) 45 instead of (decimal) 55.
That should just mean dropping the '0' (zero-fill) flag.
e.g., change System.out.printf("%03d ", x);
to the simpler System.out.printf("%3d ", x);
That error also shows when the video has played fine and the script will finish but that error always throws because the imshow() will get empty frames after all frames have been consumed.
That is especially the case if you are playing a short (few sec) video file and you don't notice that the video actually played on the background (behind your code editor) and after that the script ends with that error.
I have found this simple javascript snippet very useful.
$(document).ready(function()
{
var navbar = $('#navbar');
navbar.after('<div id="more-div" style="height: ' + navbar.outerHeight(true) + 'px" class="hidden"></div>');
var afternavbar = $('#more-div');
var abovenavbar = $('#above-navbar');
$(window).on('scroll', function()
{
if ($(window).scrollTop() > abovenavbar.height())
{
navbar.addClass('navbar-fixed-top');
afternavbar.removeClass('hidden');
}
else
{
navbar.removeClass('navbar-fixed-top');
afternavbar.addClass('hidden');
}
});
});
It might be easier with vlookup. Try this:
=IFERROR(VLOOKUP(D2,G:H,2,0),"")
The IFERROR()
is for no matches, so that it throws ""
in such cases.
VLOOKUP
's first parameter is the value to 'look for' in the reference table, which is column G and H.
VLOOKUP
will thus look for D2
in column G and return the value in the column index 2
(column G has column index 1, H will have column index 2), meaning that the value from column H will be returned.
The last parameter is 0
(or equivalently FALSE
) to mean an exact match. That's what you need as opposed to approximate match.
I made a sample WebApp in May 2012 that uses JDO 3.0 & DataNucleus 3.0 - take a look how clean it is: https://github.com/TorbenVesterager/BadAssWebApp
Okay maybe it's a little bit too clean, because I use the POJOs both for the database and the JSON client, but it's fun :)

This problem is because port 80 is used by some other application. Try to reconfigure port.
If fptr
is NULL
, then you don't have an open file. Therefore, you can't freopen
it, you should just fopen
it.
FILE *fptr;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
fptr = fopen("scores.dat", "wb");
}
note: Since the behavior of your program varies depending on whether the file is opened in read or write modes, you most probably also need to keep a variable indicating which is the case.
int main()
{
FILE *fptr;
char there_was_error = 0;
char opened_in_read = 1;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
opened_in_read = 0;
fptr = fopen("scores.dat", "wb");
if (fptr == NULL)
there_was_error = 1;
}
if (there_was_error)
{
printf("Disc full or no permission\n");
return EXIT_FAILURE;
}
if (opened_in_read)
printf("The file is opened in read mode."
" Let's read some cached data\n");
else
printf("The file is opened in write mode."
" Let's do some processing and cache the results\n");
return EXIT_SUCCESS;
}

I think Scapy is what are you looking for.
http://www.secdev.org/projects/scapy/
you can build and send frames (packets) with it
From Apache Commons IO FileNameUtils
String fileName = FilenameUtils.getName(stringNameWithPath);
Here is the example directly from PEP 8 on limiting line length:
class Rectangle(Blob):
def __init__(self, width, height,
color='black', emphasis=None, highlight=0):
if (width == 0 and height == 0 and
color == 'red' and emphasis == 'strong' or
highlight > 100):
raise ValueError("sorry, you lose")
if width == 0 and height == 0 and (color == 'red' or
emphasis is None):
raise ValueError("I don't think so -- values are %s, %s" %
(width, height))
Blob.__init__(self, width, height,
color, emphasis, highlight)
if tableFields
is an array , you can loop through elements as following :
for (item in tableFields); {
console.log(tableFields[item]);
}
by the way i saw a logical error in you'r code.just remove ;
from end of for loop
right here :
for (item in tableFields); {
.
this will cause you'r loop to do just nothing.and the following line will be executed only once :
// Do stuff

I see the question is about Express Edition, but this topic is easy to pop up in Google Search, and doesn't have a solution for other editions.
So. If you run into this problem with any VS Edition except Express, you can rerun installation and include MFC files.
You can use this code:
This example takes a backup of sugarcrm database and dumps the output to sugarcrm.sql
# mysqldump -u root -ptmppassword sugarcrm > sugarcrm.sql
# mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
The sugarcrm.sql will contain drop table, create table and insert command for all the tables in the sugarcrm database. Following is a partial output of sugarcrm.sql, showing the dump information of accounts_contacts table:
--
accounts_contacts
DROP TABLE IF EXISTS `accounts_contacts`;
SET @saved_cs_client = @@character_set_client;
SET character_set_client = utf8;
CREATE TABLE `accounts_contacts` (
`id` varchar(36) NOT NULL,
`contact_id` varchar(36) default NULL,
`account_id` varchar(36) default NULL,
`date_modified` datetime default NULL,
`deleted` tinyint(1) NOT NULL default '0',
PRIMARY KEY (`id`),
KEY `idx_account_contact` (`account_id`,`contact_id`),
KEY `idx_contid_del_accid` (`contact_id`,`deleted`,`account_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Check against any long running queries in your database.
Increasing your pool size will only make your webapp live a little longer (and probably get a lot slower)
You can use sql server profiler and filter on duration / reads to see which querys need optimization.
I also see you're probably keeping a global connection?
blnMainConnectionIsCreatedLocal
Let .net do the pooling for you and open / close your connection with a using statement.
Suggestions:
Always open and close a connection like this, so .net can manage your connections and you won't run out of connections:
using (SqlConnection conn = new SqlConnection(connectionString))
{
conn.Open();
// do some stuff
} //conn disposed
As I mentioned, check your query with sql server profiler and see if you can optimize it. Having a slow query with many requests in a web app can give these timeouts too.
I was having this problem. Things I tried:
This is what worked for me
Hope this helps someone!
This worked for me:
SELECT EXTRACT(YEAR FROM ASOFDATE) FROM PSASOFDATE;
You don't need CSS for this.
<img src="abc"/>
now with link:
<a href="#myLink"><img src="abc"/></a>
Or with jquery, later on, you can use the wrap property, see these questions answer:
classes.dex
does not make it to the final .apk
. Running gradlew --offline clean && gradlew --offline assembleDebug
fixed things for me every time. From that point you can start launching the app from Android Studio again.
EDIT: Before what I said above go to Task Manager and kill all cmd.exe
and conhost.exe
processes (or just the one in which aapt
got stuck). Otherwise aapt
would crash from now on when launched from command line with the infamous error -1073741819
.
it is possible to do this by writing:
try
{
//.......
}
catch(...) // <<- catch all
{
//.......
}
But there is a very not noticeable risk here: you can not find the exact type of error that has been thrown in the try
block, so use this kind of catch
when you are sure that no matter what the type of exception is, the program must persist in the way defined in the catch
block.
You can also use any()
, map()
like so:
if any(map(l.startswith, x)):
pass # Do something
Or alternatively, using a generator expression:
if any(l.startswith(s) for s in x)
pass # Do something
I use git for-each-ref to get a list of branches that are either merged or not merged into a given remote branch (e.g. origin/integration
)
Iterate over all refs that match <pattern> and show them according to the given <format>, after sorting them according to the given set of <key>.
Note: replace origin/integration
with integration
if you tend to use git pull
as opposed to git fetch
.
origin/integration
branchgit for-each-ref --merged=origin/integration --format="%(refname:short)" refs/heads/
# ^ ^ ^
# A B C
branch1
branch2
branch3
branch4
A: Take only the branches merged into the remote origin/integration
branch
B: Print the branch name
C: Only look at heads
refs (i.e. branches)
origin/integration
branchgit for-each-ref --no-merged=origin/integration --format="%(committerdate:short) %(refname:short)" --sort=committerdate refs/heads
# ^ ^ ^ ^
# A B C D
2020-01-14 branch10
2020-01-16 branch11
2020-01-17 branch12
2020-01-30 branch13
A: Take only the branches NOT merged into the remote origin/integration
branch
B: Print the branch name along with the last commit date
C: Sort output by commit date
D: Only look at heads
refs (i.e. branches)
As far as I know, there are 2 standard ways you can do that.
1. @Input
Whenever the data in the parent changes, the child gets notified about this in the ngOnChanges method. The child can act on it. This is the standard way of interacting with a child.
Parent-Component
public inputToChild: Object;
Parent-HTML
<child [data]="inputToChild"> </child>
Child-Component: @Input() data;
ngOnChanges(changes: { [property: string]: SimpleChange }){
// Extract changes to the input property by its name
let change: SimpleChange = changes['data'];
// Whenever the data in the parent changes, this method gets triggered. You
// can act on the changes here. You will have both the previous value and the
// current value here.
}
Creating a service and using an observable in the shared service. The child subscribes to it and whenever there is a change, the child will be notified. This is also a popular method. When you want to send something other than the data you pass as the input, this can be used.
SharedService
subject: Subject<Object>;
Parent-Component
constructor(sharedService: SharedService)
this.sharedService.subject.next(data);
Child-Component
constructor(sharedService: SharedService)
this.sharedService.subject.subscribe((data)=>{
// Whenever the parent emits using the next method, you can receive the data
in here and act on it.})
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Your Controller", action = "Your Action", id = UrlParameter.Optional }
);
}
}
Let me seperate up everything and solve approach each problem in isolation:
Authentication
For authentication, baseauth has the advantage that it is a mature solution on the protocol level. This means a lot of "might crop up later" problems are already solved for you. For example, with BaseAuth, user agents know the password is a password so they don't cache it.
Auth server load
If you dispense a token to the user instead of caching the authentication on your server, you are still doing the same thing: Caching authentication information. The only difference is that you are turning the responsibility for the caching to the user. This seems like unnecessary labor for the user with no gains, so I recommend to handle this transparently on your server as you suggested.
Transmission Security
If can use an SSL connection, that's all there is to it, the connection is secure*. To prevent accidental multiple execution, you can filter multiple urls or ask users to include a random component ("nonce") in the URL.
url = username:[email protected]/api/call/nonce
If that is not possible, and the transmitted information is not secret, I recommend securing the request with a hash, as you suggested in the token approach. Since the hash provides the security, you could instruct your users to provide the hash as the baseauth password. For improved robustness, I recommend using a random string instead of the timestamp as a "nonce" to prevent replay attacks (two legit requests could be made during the same second). Instead of providing seperate "shared secret" and "api key" fields, you can simply use the api key as shared secret, and then use a salt that doesn't change to prevent rainbow table attacks. The username field seems like a good place to put the nonce too, since it is part of the auth. So now you have a clean call like this:
nonce = generate_secure_password(length: 16);
one_time_key = nonce + '-' + sha1(nonce+salt+shared_key);
url = username:[email protected]/api/call
It is true that this is a bit laborious. This is because you aren't using a protocol level solution (like SSL). So it might be a good idea to provide some kind of SDK to users so at least they don't have to go through it themselves. If you need to do it this way, I find the security level appropriate (just-right-kill).
Secure secret storage
It depends who you are trying to thwart. If you are preventing people with access to the user's phone from using your REST service in the user's name, then it would be a good idea to find some kind of keyring API on the target OS and have the SDK (or the implementor) store the key there. If that's not possible, you can at least make it a bit harder to get the secret by encrypting it, and storing the encrypted data and the encryption key in seperate places.
If you are trying to keep other software vendors from getting your API key to prevent the development of alternate clients, only the encrypt-and-store-seperately approach almost works. This is whitebox crypto, and to date, no one has come up with a truly secure solution to problems of this class. The least you can do is still issue a single key for each user so you can ban abused keys.
(*) EDIT: SSL connections should no longer be considered secure without taking additional steps to verify them.
If you use jquery.validate.js
and jquery.validate.unobtrusive.js
for validating on client side, you should remember that you have to register any validation attribute of any DOM element on your request. Therefor you can use this code:
$.validator.unobtrusive.parse('your main element on layout');
to register all validation attributes. You can call this method on (for example) :
$(document).ajaxSuccess() or $(document).ready()
to register all of them and your validation can be occurred successfully instead of registering all js files on cshtml files.
Jquery like any other good JavaScript frameworks supplies you with functionality independent of browser platform wrapping all the intricacies, which you may not care about or don't want to care about.
I think using a framework is better instead of using pure JavaScript and doing all the stuff from scratch, unless you usage is very limited.
I definitely recommend JQuery!

I amended the code from stej (which was great, just what i needed!) to use larger buffer, [long] for larger files and used System.Diagnostics.Stopwatch class to track elapsed time and estimate time remaining.
Also added reporting of transfer rate during transfer and outputting overall elapsed time and overall transfer rate.
Using 4MB (4096*1024 bytes) buffer to get better than Win7 native throughput copying from NAS to USB stick on laptop over wifi.

If you want to open .img files, you can use 7-zip, which is freeware...
Once installed, right click on the relevant img file, hover over "7-zip", then click "Open Archive". Bear in mind, you need a seperate program, or Windows 7 to burn the image to disc!
Hope this helps!
Edit: Proof that it works (not my video, credit to howtodothe on YouTube).
Yes. You know that you can put any Object
into the Object
parameter of most JOptionPane.showXXX methods
, and often that Object
happens to be a JPanel
.
In your situation, perhaps you could use a JPanel
that has several JTextFields
in it:
import javax.swing.*;
public class JOptionPaneMultiInput {
public static void main(String[] args) {
JTextField xField = new JTextField(5);
JTextField yField = new JTextField(5);
JPanel myPanel = new JPanel();
myPanel.add(new JLabel("x:"));
myPanel.add(xField);
myPanel.add(Box.createHorizontalStrut(15)); // a spacer
myPanel.add(new JLabel("y:"));
myPanel.add(yField);
int result = JOptionPane.showConfirmDialog(null, myPanel,
"Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);
if (result == JOptionPane.OK_OPTION) {
System.out.println("x value: " + xField.getText());
System.out.println("y value: " + yField.getText());
}
}
}
You should avoid using nested selects and I would go as far to say you should never use them in the actual select part of your statement. You will be running that select for each row that is returned. This is a really expensive operation. Rather use joins. It is much more readable and the performance is much better.
In your case the query below should help. Note the cases statement is still there, but now it is a simple compare operation.
select
p.product_id,
p.type_id,
p.product_name,
p.type,
case p.type_id when 10 then (CONCAT_WS(' ' , first_name, middle_name, last_name )) else (null) end artistC
from
Product p
inner join Product_Type pt on
pt.type_id = p.type_id
left join Product_ArtistAuthor paa on
paa.artist_id = p.artist_id
where
p.product_id = $pid
I used a left join since I don't know the business logic.
Simple, but complete example showing how to display QImage might look like this:
#include <QtGui/QApplication>
#include <QLabel>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QImage myImage;
myImage.load("test.png");
QLabel myLabel;
myLabel.setPixmap(QPixmap::fromImage(myImage));
myLabel.show();
return a.exec();
}

Just put this into a separate module and call fHandleFile() with the right parameters.
Even using this won't work. I think the best solution is Browserify:

console.log("I am function 1");
},

console.log("I am function 2");
}
};
-getFunc1.js-
var common = require('./common');

You need to install ENU\x64\SQLEXPRWT_x64_ENU.exe which is Express with Tools (RTM release. SP1 release can be found here).
As the page states
Express with Tools (with LocalDB) Includes the database engine and SQL Server Management Studio Express) This package contains everything needed to install and configure SQL Server as a database server. Choose either LocalDB or Express depending on your needs above.
So install this and use the management studio included with it.

Your example code is wrong and will throw a SyntaxError. You seem to have confused the syntax of creating an object Object
with creating an Array
.
The correct syntax would be: var arr = [ "abc", "def", "ghi" ];
To remove an item from the array, based on its value, use the splice method:
arr.splice(arr.indexOf("def"), 1);
To remove it by index, just refer directly to it:
arr.splice(1, 1);
varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.
I'll jump in with the notorious "Do you really want to do that" answer.
It seems like your focus is on playing with Java and seeing what it can do. However, if you want to actually develop a web app, you should be aware that, although Java is used in web applications (and in serious ones), there are other technology options which might be more adequate.
Personally, I like (and use) Java for powerful, portable backend services on a server. I've never tried building websites with it, because it never seemed the most obvious ting to do. After growing tired of PHP (which I have been using for years), I lately fell in love with Django, a Python-based web framework.
The Ruby on Rails people have a number of very funny videos on youtube comparing different web technologies to RoR. Of course, these are obviously exaggerated and maybe slightly biased, but I'd say there's more than one grain of truth in each of them. The one about Java is here. ;-)
This would be better and easy
var arr = $('input[name="user_ids[]"]').map(function(){
return $(this).val();
}).get();
console.log(arr);

As an update for those who come across this question after 2018, if you are using Kotlin, you can simply use the Android KTX extension property ViewGroup.children to get a sequence of the View's immediate children.
Unfortunately, threads do exist. A thread is something tangible. You can kill one, and the others will still be running. You can spawn new threads.... although each thread is not it's own process, they are running separately inside the process. On multi-core machines, 2 threads could run at the same time.
Internally, string::operator==()
is using string::compare()
. Please refer to: CPlusPlus - string::operator==()
I wrote a small application to compare the performance, and apparently if you compile and run your code on debug environment the string::compare()
is slightly faster than string::operator==()
. However if you compile and run your code in Release environment, both are pretty much the same.
FYI, I ran 1,000,000 iteration in order to come up with such conclusion.
In order to prove why in debug environment the string::compare is faster, I went to the assembly and here is the code:
DEBUG BUILD
string::operator==()
if (str1 == str2)
00D42A34 lea eax,[str2]
00D42A37 push eax
00D42A38 lea ecx,[str1]
00D42A3B push ecx
00D42A3C call std::operator==<char,std::char_traits<char>,std::allocator<char> > (0D23EECh)
00D42A41 add esp,8
00D42A44 movzx edx,al
00D42A47 test edx,edx
00D42A49 je Algorithm::PerformanceTest::stringComparison_usingEqualOperator1+0C4h (0D42A54h)
string::compare()
if (str1.compare(str2) == 0)
00D424D4 lea eax,[str2]
00D424D7 push eax
00D424D8 lea ecx,[str1]
00D424DB call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0D23582h)
00D424E0 test eax,eax
00D424E2 jne Algorithm::PerformanceTest::stringComparison_usingCompare1+0BDh (0D424EDh)
You can see that in string::operator==(), it has to perform extra operations (add esp, 8 and movzx edx,al)
RELEASE BUILD
string::operator==()
if (str1 == str2)
008533F0 cmp dword ptr [ebp-14h],10h
008533F4 lea eax,[str2]
008533F7 push dword ptr [ebp-18h]
008533FA cmovae eax,dword ptr [str2]
008533FE push eax
008533FF push dword ptr [ebp-30h]
00853402 push ecx
00853403 lea ecx,[str1]
00853406 call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0853B80h)
string::compare()
if (str1.compare(str2) == 0)
00853830 cmp dword ptr [ebp-14h],10h
00853834 lea eax,[str2]
00853837 push dword ptr [ebp-18h]
0085383A cmovae eax,dword ptr [str2]
0085383E push eax
0085383F push dword ptr [ebp-30h]
00853842 push ecx
00853843 lea ecx,[str1]
00853846 call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0853B80h)
Both assembly code are very similar as the compiler perform optimization.
Finally, in my opinion, the performance gain is negligible, hence I would really leave it to the developer to decide on which one is the preferred one as both achieve the same outcome (especially when it is release build).

It doesn't matter if the random_state is 0 or 1 or any other integer. What matters is that it should be set the same value, if you want to validate your processing over multiple runs of the code. By the way I have seen random_state=42
used in many official examples of scikit as well as elsewhere also.
random_state
as the name suggests, is used for initializing the internal random number generator, which will decide the splitting of data into train and test indices in your case. In the documentation, it is stated that:
If random_state is None or np.random, then a randomly-initialized RandomState object is returned.
If random_state is an integer, then it is used to seed a new RandomState object.
If random_state is a RandomState object, then it is passed through.
This is to check and validate the data when running the code multiple times. Setting random_state
a fixed value will guarantee that same sequence of random numbers are generated each time you run the code. And unless there is some other randomness present in the process, the results produced will be same as always. This helps in verifying the output.
System.Reflection.Assembly.GetExecutingAssembly()
.Location
1
Combine that with System.IO.Path.GetDirectoryName
if all you want is the directory.
1As per Mr.Mindor's comment:
System.Reflection.Assembly.GetExecutingAssembly().Location
returns where the executing assembly is currently located, which may or may not be where the assembly is located when not executing. In the case of shadow copying assemblies, you will get a path in a temp directory.System.Reflection.Assembly.GetExecutingAssembly().CodeBase
will return the 'permanent' path of the assembly.
It does not return an Array
, it returns a NodeList.
Let us add this workaround that works on my laptop!
Mac with Osx Mojave 10.14.5
Mysql 8.0.17 was installed with homebrew
I run the following command to locate the path of mysql
brew info mysql
Once the path is known, I run this :
/usr/local/Cellar/mysql/8.0.17/bin/mysqld_safe --skip-grant-table
In another terminal I run :
mysql -u root
Inside that terminal, I changed the root password using :
update mysql.user set authentication_string='NewPassword' where user='root';
and to finish I run :
FLUSH PRIVILEGES;
And voila the password was reset.
This question is 6 years old, but strangely, none of the answers really addresses all four points (speed, memory, expressiveness, portability).
Obviously this is implementation-dependent, but because JSON is so widely used, and so easy to implement, it has tended to receive greater native support, and hence speed. Considering that YAML does everything that JSON does, plus a truckload more, it's likely that of any comparable implementations of both, the JSON one will be quicker.
However, given that a YAML file can be slightly smaller than its JSON counterpart (due to fewer "
and ,
characters), it's possible that a highly optimised YAML parser might be quicker in exceptional circumstances.
Basically the same argument applies. It's hard to see why a YAML parser would ever be more memory efficient than a JSON parser, if they're representing the same data structure.
As noted by others, Python programmers tend towards preferring YAML, JavaScript programmers towards JSON. I'll make these observations:
It's hard to imagine a modern language without a JSON library. It's also hard to imagine a JSON parser implementing anything less than the full spec. YAML has widespread support, but is less ubiquitous than JSON, and each parser implements a different subset. Hence YAML files are less interoperable than you might think.
JSON is the winner for performance (if relevant) and interoperability. YAML is better for human-maintained files. HJSON is a decent compromise although with much reduced portability. JSON5 is a more reasonable compromise, with well-defined syntax.
Finally I manage to ignore the invalid characters and get only the numbers to convert the text to numeric.
SELECT (NULLIF(regexp_replace(split_part(column1, '.', 1), '\D','','g'), '')

You can use PHP strtr() function to get rid of accented characters :
$string = "Éric Cantona";
$accented_array = array('Š'=>'S', 'š'=>'s', 'Ž'=>'Z', 'ž'=>'z', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E','Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O', 'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U','Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss', 'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c','è'=>'e', 'é'=>'e', 'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o', 'ô'=>'o', 'õ'=>'o','ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'þ'=>'b', 'ÿ'=>'y' );
$required_str = strtr( $string, $accented_array );
The "delete module-info.java at your Project Explorer tab" answer is the easiest and most straightforward answer, but
for those who would want a little more understanding or control of what's happening, the following alternate methods may be desirable;

In my case, I found that I need the -f option. Such as the following:
git rm -f first_file.txt

Using java 8 LocalDateTime
and java 7 try-with statement:
public class WriteFile {
public static void main(String[] args) {
String timeLog = DateTimeFormatter.ofPattern("yyyyMMdd_HHmmss").format(LocalDateTime.now());
File logFile = new File(timeLog);
try (BufferedWriter bw = new BufferedWriter(new FileWriter(logFile)))
{
System.out.println("File was written to: " + logFile.getCanonicalPath());
bw.write("Hello world!");
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
Try this one
textBox1.Text = "Line1" + Environment.NewLine + "Line2";
Working fine for me...
This worked:
$("#theSelectId").prepend("<option value='' selected='selected'></option>");
Firebug Output:
<select id="theSelectId">
<option selected="selected" value=""/>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
You could also use .prependTo
if you wanted to reverse the order:
?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????
To see what version you have on your Mac(Window also can run that code.), run react-native -v
and you should get something like this:
If you want to know what version your project is running, look in /node_modules/react-native/package.json
and look for the version
key:
Here is the way to go:
Runtime rt = Runtime.getRuntime();
String[] commands = {"system.exe", "-get t"};
Process proc = rt.exec(commands);
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(proc.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(proc.getErrorStream()));
// Read the output from the command
System.out.println("Here is the standard output of the command:\n");
String s = null;
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
// Read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}
Read the Javadoc for more details here. ProcessBuilder
would be a good choice to use.
I would do a
git diff commit1..commit2 filepattern | git-apply --index && git commit
This way you can limit the range of commits for a filepattern from a branch.
It is stolen from Re: How to pull only a few files from one branch to another?
As for the code example in the question, the standard solution is to reference the class explicitly by its name, and it is even possible to do without getClassLoader()
call:
class MyClass {
public static void startMusic() {
URL songPath = MyClass.class.getResource("background.midi");
}
}
This approach still has a back side that it is not very safe against copy/paste errors in case you need to replicate this code to a number of similar classes.
And as for the exact question in the headline, there is a trick posted in the adjacent thread:
Class currentClass = new Object() { }.getClass().getEnclosingClass();
It uses a nested anonymous Object
subclass to get hold of the execution context. This trick has a benefit of being copy/paste safe...
Caution when using this in a Base Class that other classes inherit from:
It is also worth noting that if this snippet is shaped as a static method of some base class then currentClass
value will always be a reference to that base class rather than to any subclass that may be using that method.
Whenever you use
export someobject
and someobject is
{
"prop1":"Property1",
"prop2":"Property2",
}
the above you can import anywhere using import
or module.js
and there you can use someobject. This is not a restriction that someobject will be an object only it can be a function too, a class or an object.
When you say
new Object()
like you said
new Vue({
el: '#app',
data: []
)}
Here you are initiating an object of class Vue.
I hope my answer explains your query in general and more explicitly.

| |------------------build/ <--'static' folder, constructed by Grunt
| |--<proj |----vendors/ <-- angular.js and others here
| |-- folders> |----src/ <-- your js
| |----index.html <-- your SPA entrypoint
|------<proj
|------ folders>

I use following solution:
...
root = os.path.join(os.path.dirname(os.path.abspath(__file__)), "ui", "build")
@app.route('/<path:path>', methods=['GET'])
def static_proxy(path):
return send_from_directory(root, path)
@app.route('/', methods=['GET'])
def redirect_to_index():
return send_from_directory(root, 'index.html')

Object is a collection of methods and variables.You can't print the variables in object by just cout operation . if you want to show the things inside the object you have to declare either a getter or a display text method in class.
ex
#include <iostream>
using namespace std;
class mystruct
{
private:
int m_a;
float m_b;
public:
mystruct(int x, float y)
{
m_a = x;
m_b = y;
}
public:
void getm_aAndm_b()
{
cout<<m_a<<endl;
cout<<m_b<<endl;
}
};
int main()
{
mystruct m = mystruct(5,3.14);
cout << "my structure " << endl;
m.getm_aAndm_b();
return 0;
}

In Notepad++ on the Language menu you will find the menu item - 'J' and under this menu item chose the language - JSON.
Once you select the JSON language then you won't have to worry about how to save it. When you save it it will by default save it as .JSON file, you have to just select the location of the file.

You get the number of unix seconds, not milliseconds!
You you need to multiply it with 1000 or using valueOf()
and don't forget to use a formatter, since you are using a non ISO 8601 format. And if you forget to pass the formatter, the date will be parsed in the UTC timezone or as an invalid date.

The differences I could see is that Robocopy has a lot more options, but I didn't find any of them particularly helpful unless I'm doing something special.
I did some benchmarking of several copy routines and found XCOPY and ROBOCOPY to be the fastest, but to my surprise, XCOPY consistently edged out Robocopy.
It's ironic that robocopy retries a copy that fails, but it also failed a lot in my benchmark tests, where xcopy never did.
I did full file (byte by byte) file compares after my benchmark tests.
Here are the switches I used with robocopy in my tests:
**"/E /R:1 /W:1 /NP /NFL /NDL"**.
If anyone knows a faster combination (other than removing /E, which I need), I'd love to hear.
Another interesting/disappointing thing with robocopy is that if a copy does fail, by default it retries 1,000,000 times with a 30 second delay between each try. If you are running a long batch file unattended, you may be very disappointed when you come back after a few hours to find it's still trying to copy a particular file.
The /R and /W switches let you change this behavior.
If there's a way to attach files here, I can share my results.
I also included FastCopy and Windows Copy in my tests and each test was run 10 times. Note, the differences were pretty significant. The 95% confidence intervals had no overlap.
I was using Postman to test my Laravel API.
I received an error that stated
"SQLSTATE[42S22]: Column not found: 1054 Unknown column" because Laravel was trying to automatically create two columns "created_at" and "updated_at".
I had to enter public $timestamps = false;
to my model. Then, I tested again with Postman and saw that an "id" = 0
variable was being created in my database.
I finally had to add public $incrementing false;
to fix my API.
To do this, you can reset you local git repository to the first commit hashtag, so all your changes after that commit will be unstaged, then you can commit with --amend option.
git reset your-first-commit-hashtag
git add .
git commit --amend
And then edit the first commit nam if needed and save file.
Also, name it divrat.m
, not divrat.M
. This shouldn't matter on most OSes, but who knows...
You can also test whether matlab can find a function by using the which
command, i.e.
which divrat
A less verbose approach:
int number = [dict[@"integer"] intValue];
The root of the answer is that the person asking the question needs to have a JavaScript interpreter to get what they are after. What I have found is I am able to get all of the information I wanted on a website in json before it was interpreted by JavaScript. This has saved me a ton of time in what would be parsing html hoping each webpage is in the same format.
So when you get a response from a website using requests really look at the html/text because you might find the javascripts JSON in the footer ready to be parsed.

The seamless
attribute no longer exists. It was originally pitched to be included in the first HTML5 spec, but subsequently dropped. An unrelated attribute of the same name made a brief cameo in the HTML5.1 draft, but that too was ditched mid-2016:
So I think the gist of it all both from the implementor side and the web-dev side is that
seamless
as-specced doesn’t seem to be what anybody wanted to begin with. Or at least it’s more than anybody actually wanted. And anyway like @annevk says, it’s seems a lot of it’s since been “overcome by events” in light of Shadow DOM.
In other words: purge the seamless
attribute from your memory, and pretend it never existed.
For posterity's sake, here's my original answer from five years ago:
The attribute is in draft mode at the moment. For that reason, none of the current browsers are supporting it yet (as the implementation is subject to change). In the meantime, it's best just to use CSS to strip the borders/scrollbars from the iframe:
iframe[seamless]{
background-color: transparent;
border: 0px none transparent;
padding: 0px;
overflow: hidden;
}
There's more to the seamless attribute than what can be added with CSS: part of the reasoning behind the attribute was to allow nested content to inherit the same styles applied to the iframe (acting as though the embedded document was one big nested inside the element, for example).
Lastly, versions of Internet Explorer (8 and earlier) require additional attributes in order to remove the borders, scrollbars and background colour:
<iframe frameborder="0" allowtransparency="true" scrolling="no" src="..."></iframe>
Naturally, this doesn't validate. So it's up to you how to handle it. My (picky) approach would be to sniff the agent string and add the attributes for IE versions earlier than 9.
Hope that helps. :)

For older versions try
yourSparkConf.set("spark.hadoop.validateOutputSpecs", "false")
val sc = SparkContext(yourSparkConf)
In 1.1.0 you can set conf settings using the spark-submit script with the --conf flag.
WARNING (older versions): According to @piggybox there is a bug in Spark where it will only overwrite files it needs to to write it's part-
files, any other files will be left unremoved.
I ran into this error in a different situation, posting the resolution for those arriving via search: from within Visual Studio, I had copied a file from one project and pasted into another. Turns out that creates a symbolic link, not an actual copy. Thus the project did not find the file in the current working directory as expected. When I made a physical copy instead, in Windows Explorer, suddenly #include "myfile.h"
worked.
For Each row As DataGridViewRow In yourDGV.SelectedRows
yourDGV.Rows.Remove(row)
Next
This will delete all rows that had been selected.
git show somebranch:path/to/your/file
you can also do multiple files and have them concatenated:
git show branchA~10:fileA branchB^^:fileB
You do not have to provide the full path to the file, relative paths are acceptable e.g.:
git show branchA~10:../src/hello.c
If you want to get the file in the local directory (revert just one file) you can checkout:
git checkout somebranch^^^ -- path/to/file
For checking existence one can also use (works for both, files and folders):
Not Dir(DirFile, vbDirectory) = vbNullString
The result is True
if a file or a directory exists.
Example:
If Not Dir("C:\Temp\test.xlsx", vbDirectory) = vbNullString Then MsgBox "exists" Else MsgBox "does not exist" End If
This is the right way to do it.
try
{
Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW);
File file = new File(aFile.getAbsolutePath());
String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString());
String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
myIntent.setDataAndType(Uri.fromFile(file),mimetype);
startActivity(myIntent);
}
catch (Exception e)
{
// TODO: handle exception
String data = e.getMessage();
}
you need to import import android.webkit.MimeTypeMap;
Change your network adapter to a bridged connection, this will directly connect to your computers physical network.

I always use this code for situations like this. beside you can recognize two or three or more digit numbers.
You can use:
echo '<?php if(function_exists("my_func")) echo "function exists"; ' | php
The short tag "< ?=" can be helpful too:
echo '<?= function_exists("foo") ? "yes" : "no";' | php
echo '<?= 8+7+9 ;' | php
The closing tag "?>" is optional, but don't forget the final ";"!
Short and nice. No other dependencies, than extended std C lib.
strcasecmp(str1.c_str(), str2.c_str()) == 0
returns true if str1
and str2
are equal.
strcasecmp
may not exist, there could be analogs stricmp
, strcmpi
, etc.
Example code:
#include <iostream>
#include <string>
#include <string.h> //For strcasecmp(). Also could be found in <mem.h>
using namespace std;
/// Simple wrapper
inline bool str_ignoreCase_cmp(std::string const& s1, std::string const& s2) {
if(s1.length() != s2.length())
return false; // optimization since std::string holds length in variable.
return strcasecmp(s1.c_str(), s2.c_str()) == 0;
}
/// Function object - comparator
struct StringCaseInsensetiveCompare {
bool operator()(std::string const& s1, std::string const& s2) {
if(s1.length() != s2.length())
return false; // optimization since std::string holds length in variable.
return strcasecmp(s1.c_str(), s2.c_str()) == 0;
}
bool operator()(const char *s1, const char * s2){
return strcasecmp(s1,s2)==0;
}
};
/// Convert bool to string
inline char const* bool2str(bool b){ return b?"true":"false"; }
int main()
{
cout<< bool2str(strcasecmp("asd","AsD")==0) <<endl;
cout<< bool2str(strcasecmp(string{"aasd"}.c_str(),string{"AasD"}.c_str())==0) <<endl;
StringCaseInsensetiveCompare cmp;
cout<< bool2str(cmp("A","a")) <<endl;
cout<< bool2str(cmp(string{"Aaaa"},string{"aaaA"})) <<endl;
cout<< bool2str(str_ignoreCase_cmp(string{"Aaaa"},string{"aaaA"})) <<endl;
return 0;
}
Output:
true
true
true
true
true
It may happen that "this.checked" is always "on". Therefore, I recommend:
$('#checkbox').change(function() {
if ($(this).is(':checked')) {
console.log('Checked');
} else {
console.log('Unchecked');
}
});
sklearn.linear_model.LinearRegression
will do it:
from sklearn import linear_model
clf = linear_model.LinearRegression()
clf.fit([[getattr(t, 'x%d' % i) for i in range(1, 8)] for t in texts],
[t.y for t in texts])
Then clf.coef_
will have the regression coefficients.
sklearn.linear_model
also has similar interfaces to do various kinds of regularizations on the regression.
To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):
OPS
is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.
Rank is set with a right click on a data point selected in that column and Show Values As...
and Rank Largest to Smallest
(there are other options) with the Base field as Player
and the filter is a Value Filters
, Top 10...
one:
Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).
In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5
for Top 5.
Here's the calling order:
app.config()
app.run()
app.controller()
Here's a simple demo where you can watch each one executing (and experiment if you'd like).
From Angular's module docs:
Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.
Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the services have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.
One situation where run blocks are used is during authentications.
The following works for me in Firefox and Chrome. In Firefox it even works from file:///
models/course.js
export function Course() {
this.id = '';
this.name = '';
};
models/student.js
import { Course } from './course.js';
export function Student() {
this.firstName = '';
this.lastName = '';
this.course = new Course();
};
index.html
<div id="myDiv">
</div>
<script type="module">
import { Student } from './models/student.js';
window.onload = function () {
var x = new Student();
x.course.id = 1;
document.getElementById('myDiv').innerHTML = x.course.id;
}
</script>
I've had success with this solution. It's almost like Patrick's, with a little twist. You can use these expressions separately or in sequence. If the parameter is blank, it will be ignored and all values for the column that your searching will be displayed, including NULLS.
SELECT * FROM MyTable
WHERE
--check to see if @param1 exists, if @param1 is blank, return all
--records excluding filters below
(Col1 LIKE '%' + @param1 + '%' OR @param1 = '')
AND
--where you want to search multiple columns using the same parameter
--enclose the first 'OR' expression in braces and enclose the entire
--expression
((Col2 LIKE '%' + @searchString + '%' OR Col3 LIKE '%' + @searchString + '%') OR @searchString = '')
AND
--if your search requires a date you could do the following
(Cast(DateCol AS DATE) BETWEEN CAST(@dateParam AS Date) AND CAST(GETDATE() AS DATE) OR @dateParam = '')
The book has a note how to find help on tag sets, e.g.:
nltk.help.upenn_tagset()
Others are probably similar. (Note: Maybe you first have to download tagsets
from the download helper's Models section for this)
Check the version of the excel, if you are using older version then Value2 is not available for you and thus it is showing an error, while it will work with 2007+ version. Or the other way, the object is not getting created and thus the Value2 property is not available for the object.
if you are talking about in the reference of String Class. so you can use
subString/split
for Explode & use String
concate
for Implode.
A bit verbose but this is how I do it:
@click="$emit('click', $event)"
UPDATE: Example added by @sparkyspider
<div-container @click="doSomething"></div-container>
In div-container
component...
<template>
<div @click="$emit('click', $event);">The inner div</div>
</template>
All your problems derive from this
byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;
Which are enclosed in a try, catch block, the problem is that in case the program found an exception you are not returning anything. Put it like this (modify it as your program logic stands):
public static byte[] encrypt(String toEncrypt) throws Exception{
try{
String plaintext = toEncrypt;
String key = "01234567890abcde";
String iv = "fedcba9876543210";
SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());
Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;
} catch(Exception e){
return null; // Always must return something
}
}
For the second one you must catch the Exception from the encrypt method call, like this (also modify it as your program logic stands):
public void actionPerformed(ActionEvent e)
.
.
.
try {
byte[] encrypted = encrypt(concatURL);
String encryptedString = bytesToHex(encrypted);
content.removeAll();
content.add(new JLabel("Concatenated User Input -->" + concatURL));
content.add(encryptedTextField);
setContentPane(content);
} catch (Exception exc) {
// TODO: handle exception
}
}
The lessons you must learn from this:
I use this method for logging when I want to quickly optimize different page loads. It's a little tip...
Logging to a TABLE
SET global general_log = 1;
SET global log_output = 'table';
You can then select from my mysql.general_log
table to retrieve recent queries.
I can then do something similar to tail -f
on the mysql.log, but with more refinements...
select * from mysql.general_log
where event_time > (now() - INTERVAL 8 SECOND) and thread_id not in(9 , 628)
and argument <> "SELECT 1" and argument <> ""
and argument <> "SET NAMES 'UTF8'" and argument <> "SHOW STATUS"
and command_type = "Query" and argument <> "SET PROFILING=1"
This makes it easy to see my queries that I can try and cut back. I use 8 seconds interval to only fetch queries executed within the last 8 seconds.
This is for the more complex case where the values are not just between 0 and 1; the cmap needs to be shared instead of just using the last one.
import numpy as np
from matplotlib.colors import Normalize
import matplotlib.pyplot as plt
import matplotlib.cm as cm
fig, axes = plt.subplots(nrows=2, ncols=2)
cmap=cm.get_cmap('viridis')
normalizer=Normalize(0,4)
im=cm.ScalarMappable(norm=normalizer)
for i,ax in enumerate(axes.flat):
ax.imshow(i+np.random.random((10,10)),cmap=cmap,norm=normalizer)
ax.set_title(str(i))
fig.colorbar(im, ax=axes.ravel().tolist())
plt.show()
It's programmer preference. Personally, I love using this
since it explicitly marks the object members. Of course the _
does the same thing (only when you follow the convention)
What I did was download my sql dump in a "db-dump" folder, and mounted it:
mysql:
image: mysql:5.6
environment:
MYSQL_ROOT_PASSWORD: pass
ports:
- 3306:3306
volumes:
- ./db-dump:/docker-entrypoint-initdb.d
When I run docker-compose up
for the first time, the dump is restored in the db.
It may sound silly but in my case the USB cable was too long (even if good quality). It worked with my tablet but not with the phone. To check this, if you run on Linux run lsusb to make sure that your device is at least officially connect to the usb port.

I saw this post about a month ago when I was having similar problems. I needed y-axis scrolling for a table inside of a ui dialog (yes, you heard me right). I was lucky, in that a working solution presented itself fairly quickly. However, it wasn't long before the solution took on a life of its own, but more on that later.
The problem with just setting the top level elements (thead, tfoot, and tbody) to display block, is that browser synchronization of the column sizes between the various components is quickly lost and everything packs to the smallest permissible size. Setting the widths of the columns seems like the best course of action, but without setting the widths of all the internal table components to match the total of these columns, even with a fixed table layout, there is a slight divergence between the headers and body when a scroll bar is present.
The solution for me was to set all the widths, check if a scroll bar was present, and then take the scaled widths the browser had actually decided on, and copy those to the header and footer adjusting the last column width for the size of the scroll bar. Doing this provides some fluidity to the column widths. If changes to the table's width occur, most major browsers will auto-scale the tbody column widths accordingly. All that's left is to set the header and footer column widths from their respective tbody sizes.
$table.find("> thead,> tfoot").find("> tr:first-child")
.each(function(i,e) {
$(e).children().each(function(i,e) {
if (i != column_scaled_widths.length - 1) {
$(e).width(column_scaled_widths[i] - ($(e).outerWidth() - $(e).width()));
} else {
$(e).width(column_scaled_widths[i] - ($(e).outerWidth() - $(e).width()) + $.position.scrollbarWidth());
}
});
});
This fiddle illustrates these notions: http://jsfiddle.net/borgboyone/gbkbhngq/.
Note that a table wrapper or additional tables are not needed for y-axis scrolling alone. (X-axis scrolling does require a wrapping table.) Synchronization between the column sizes for the body and header will still be lost if the minimum pack size for either the header or body columns is encountered. A mechanism for minimum widths should be provided if resizing is an option or small table widths are expected.
The ultimate culmination from this starting point is fully realized here: http://borgboyone.github.io/jquery-ui-table/
A.
char c = '1';
int i = (int)(c-'0');
and you can create a static method out of it:
static int ToInt(this char c)
{
return (int)(c - '0');
}
I have just experienced the same error, in my case it was caused by the second parameter in angular.module
being missing- hopefully this may help someone with the same issue.
angular.module('MyApp');
angular.module('MyApp', []);
By lines I assume you mean rows in the table person
. What you're looking for is:
select p.name
from person p
where p.name LIKE '%A%'; --contains the character 'A'
The above is case sensitive. For a case insensitive search, you can do:
select p.name
from person p
where UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'
For the special character, you can do:
select p.name
from person p
where p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)
The LIKE
operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the %
sign as it means match zero or more characters.
We can do it by simple means:
In FirstActivity:
Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("uid", uid.toString());
intent.putExtra("pwd", pwd.toString());
startActivity(intent);
In SecondActivity:
try {
Intent intent = getIntent();
String uid = intent.getStringExtra("uid");
String pwd = intent.getStringExtra("pwd");
} catch (Exception e) {
e.printStackTrace();
Log.e("getStringExtra_EX", e + "");
}
If you don't want to use html/dom, you could use regex. I haven't tested this; but something along the lines of:
function parseHtmlEntities(str) {
return str.replace(/&#([0-9]{1,3});/gi, function(match, numStr) {
var num = parseInt(numStr, 10); // read num as normal number
return String.fromCharCode(num);
});
}
Note: this would only work for numeric html-entities, and not stuff like &oring;.
Fixed the function (some typos), test here: http://jsfiddle.net/Be2Bd/1/
It depends on the Markdown rendering engine and the Markdown flavour. There is no standard for this. If you mean GitHub flavoured Markdown for example, shell
should work fine. Aliases are sh
, bash
or zsh
. You can find the list of available syntax lexers here.
There are two ways, one is defined in html when you define table headers
<thead>
<th data-orderable="false"></th>
</thead>
Another way is using javascript, for example, you have table
<table id="datatables">
<thead>
<tr>
<th class="testid input">test id</th>
<th class="testname input">test name</th>
</thead>
</table>
then,
$(document).ready(function() {
$('#datatables').DataTable( {
"columnDefs": [ {
"targets": [ 0], // 0 indicates the first column you define in <thead>
"searchable": false
}
, {
// you can also use name to get the target column
"targets": 'testid', // name is the class you define in <th>
"searchable": false
}
]
}
);
}
);
Use requests
library to GET, POST, PUT or DELETE by hitting a REST API endpoint. Pass the rest api endpoint url in url
, payload(dict) in data
and header/metadata in headers
import requests, json
url = "bugs.python.org"
payload = {"number": 12524,
"type": "issue",
"action": "show"}
header = {"Content-type": "application/x-www-form-urlencoded",
"Accept": "text/plain"}
response_decoded_json = requests.post(url, data=payload, headers=header)
response_json = response_decoded_json.json()
print response_json
Any recommendation on how to fix this?
Several. You can use bind:
for (i = 0; i < j; i++) {
asycronouseProcess(function (i) {
alert(i);
}.bind(null, i));
}
Or, if your browser supports let (it will be in the next ECMAScript version, however Firefox already supports it since a while) you could have:
for (i = 0; i < j; i++) {
let k = i;
asycronouseProcess(function() {
alert(k);
});
}
Or, you could do the job of bind
manually (in case the browser doesn't support it, but I would say you can implement a shim in that case, it should be in the link above):
for (i = 0; i < j; i++) {
asycronouseProcess(function(i) {
return function () {
alert(i)
}
}(i));
}
I usually prefer let
when I can use it (e.g. for Firefox add-on); otherwise bind
or a custom currying function (that doesn't need a context object).
SELECT is_read_committed_snapshot_on FROM sys.databases
WHERE name= 'YourDatabase'
Return value:
READ_COMMITTED_SNAPSHOT
option is ON. Read operations under the READ COMMITTED
isolation level are based on snapshot scans and do not acquire locks.READ_COMMITTED_SNAPSHOT
option is OFF. Read operations under the READ COMMITTED
isolation level use Shared (S) locks.I had a problem similar to the one posed in the original question. I was intrigued by the divs styled as table elements (didn't know you could do that!) and gave it a run. However, my solution was to keep my tables wrapped in tags, but rename each input and select option to become the keys of array, which I'm now parsing to get each element in the selected row.
Here's a single row from the table. Note that key [4] is the rendered ID of the row in the database from which this table row was retrieved:
<table>
<tr>
<td>DisabilityCategory</td>
<td><input type="text" name="FormElem[4][ElemLabel]" value="Disabilities"></td>
<td><select name="FormElem[4][Category]">
<option value="1">General</option>
<option value="3">Disability</option>
<option value="4">Injury</option>
<option value="2"selected>School</option>
<option value="5">Veteran</option>
<option value="10">Medical</option>
<option value="9">Supports</option>
<option value="7">Residential</option>
<option value="8">Guardian</option>
<option value="6">Criminal</option>
<option value="11">Contacts</option>
</select></td>
<td>4</td>
<td style="text-align:center;"><input type="text" name="FormElem[4][ElemSeq]" value="0" style="width:2.5em; text-align:center;"></td>
<td>'ccpPartic'</td>
<td><input type="text" name="FormElem[4][ElemType]" value="checkbox"></td>
<td><input type="checkbox" name="FormElem[4][ElemRequired]"></td>
<td><input type="text" name="FormElem[4][ElemLabelPrefix]" value=""></td>
<td><input type="text" name="FormElem[4][ElemLabelPostfix]" value=""></td>
<td><input type="text" name="FormElem[4][ElemLabelPosition]" value="before"></td>
<td><input type="submit" name="submit[4]" value="Commit Changes"></td>
</tr>
</table>
Then, in PHP, I'm using the following method to store in an array ($SelectedElem) each of the elements in the row corresponding to the submit button. I'm using print_r()
just to illustrate:
$SelectedElem = implode(",", array_keys($_POST['submit']));
print_r ($_POST['FormElem'][$SelectedElem]);
Perhaps this sounds convoluted, but it turned out to be quite simple, and it preserved the organizational structure of the table.
As there is no implementation of a variable it can't be abstract ;)
I have finalized the code for phone numbers +9 (987) 124124.
Unicode characters occupy 4 bytes.
public static String stripNonDigitsV2( CharSequence input ) {

CharBuffer buffer = CharBuffer.wrap( input );
int i=0;
while ( i< buffer.length() ) { //buffer.hasRemaining()
char chr = buffer.get(i);
if (chr=='u'){
i=i+5;
chr=buffer.get(i);
}
if ( chr > 39 && chr < 58 )
result[cursor++] = chr;
i=i+1;
}
return new String( result, 0, cursor );
}
<form target="_blank" [....]
will submit the form in a new tab... I am not sure if is this what you are looking for, please explain better...
It's an old question, but I don't see mentioned that, depending on the details, the sharey
option may be able to do all of this for you, instead of digging up axis limits, margins, etc. There's a demo in the docs that shows how to use sharex
, but the same can be done with y-axes.
When you use ANNs, you rarely know about the internals of the systems you want to learn. Some things cannot be learned without a bias. E.g., have a look at the following data: (0, 1), (1, 1), (2, 1), basically a function that maps any x to 1.
If you have a one layered network (or a linear mapping), you cannot find a solution. However, if you have a bias it's trivial!
In an ideal setting, a bias could also map all points to the mean of the target points and let the hidden neurons model the differences from that point.
After the initial posting of this question in 2010, a lot has changed in the realm of good random functions and hardware support for them.
Looking at the accepted answer from today's perspective, this algorithm is very bad in uniformity of the random numbers drawn from it. And the uniformity suffers a lot depending on the magnitude of the input values and visible artifacts/patterns will become apparent when sampling from it for e.g. ray/path tracing applications.
There have been many different functions (most of them integer hashing) being devised for this task, for different input and output dimensionality, most of which are being evaluated in the 2020 JCGT paper Hash Functions for GPU Rendering. Depending on your needs you could select a function from the list of proposed functions in that paper and simply from the accompanying Shadertoy. One that isn't covered in this paper but that has served me very well without any noticeably patterns on any input magnitude values is also one that I want to highlight.
Other classes of algorithms use low-discrepancy sequences to draw pseudo-random numbers from, such as the Sobol squence with Owen-Nayar scrambling. Eric Heitz has done some amazing research in this area, as well with his A Low-Discrepancy Sampler that Distributes Monte Carlo Errors as a Blue Noise in Screen Space paper. Another example of this is the (so far latest) JCGT paper Practical Hash-based Owen Scrambling, which applies Owen scrambling to a different hash function (namely Laine-Karras).
Yet other classes use algorithms that produce noise patterns with desirable frequency spectrums, such as blue noise, that is particularly "pleasing" to the eyes.
(I realize that good StackOverflow answers should provide the algorithms as source code and not as links because those can break, but there are way too many different algorithms nowadays and I intend for this answer to be a summary of known-good algorithms today)
You have to do binding in a directive. Look at this:
angular.module('ng', []).
directive('sliderRange', function($parse, $timeout){
return {
restrict: 'A',
replace: true,
transclude: false,
compile: function(element, attrs) {
var html = '<div class="slider-range"></div>';
var slider = $(html);
element.replaceWith(slider);
var getterLeft = $parse(attrs.ngModelLeft), setterLeft = getterLeft.assign;
var getterRight = $parse(attrs.ngModelRight), setterRight = getterRight.assign;
return function (scope, slider, attrs, controller) {
var vsLeft = getterLeft(scope), vsRight = getterRight(scope), f = vsLeft || 0, t = vsRight || 10;
var processChange = function() {
var vs = slider.slider("values"), f = vs[0], t = vs[1];
setterLeft(scope, f);
setterRight(scope, t);
}
slider.slider({
range: true,
min: 0,
max: 10,
step: 1,
change: function() { setTimeout(function () { scope.$apply(processChange); }, 1) }
}).slider("values", [f, t]);
};
}
};
});
This shows you an example of a slider range, done with jQuery UI. Example usage:
<div slider-range ng-model-left="question.properties.range_from" ng-model-right="question.properties.range_to"></div>
set ORACLE_SID=<YOUR_SID>
sqlplus "/as sysdba"
alter system disable restricted session;
or maybe
shutdown abort;
or maybe
lsnrctl stop
lsnrctl start
Use one of these commands in the terminal (with the Angular CLI installed already):
$ ng --version
or
$ ng v
But note that depending on the folder you are in, you will get different results.
If you are NOT in an angular project folder, then will see a result like this with no clearly stated Angular: version
line, unless referring to the angular core
in the package block (as the version) :)
Angular CLI: 11.0.4
Node: 14.15.1
OS: win32 x64
Angular:

And if you run the command IN an angular project folder, you will see a similar result like this with the Angular: 8.2.14
