You may also use ggarrange from ggpubr package and set "common.legend = TRUE":
library(ggpubr)
dsamp <- diamonds[sample(nrow(diamonds), 1000), ]
p1 <- qplot(carat, price, data = dsamp, colour = clarity)
p2 <- qplot(cut, price, data = dsamp, colour = clarity)
p3 <- qplot(color, price, data = dsamp, colour = clarity)
p4 <- qplot(depth, price, data = dsamp, colour = clarity)
ggarrange(p1, p2, p3, p4, ncol=2, nrow=2, common.legend = TRUE, legend="bottom")

This is how I got rid of the error:
WebDriverException: Error forwarding the new session cannot find : {platform=WINDOWS, ensureCleanSession=true, browserName=internet explorer, version=11}
In your nodeconfig.json, the version must be a String, not an integer.
So instead of using "version": 11
use "version": "11"
(note the double quotes).
A full example of a working nodecondig.json file for a RemoteWebDriver:

I recommend this plugin: HTML/CSS/JS Prettify, It really works.
After the installation, just select the code and press Ctrl+Shift+H.
Done!
In your function form
is a DOM object, In order to use attr()
you need to convert it to jQuery object.
function f(form, fname, lname) {
action = $(form).attr("action");
$.post(att, {fname : fname , lname :lname}).done(function (data) {
alert(data);
});
return true;
}
With .serialize()
function f(form, fname, lname) {
action = $(form).attr("action");
$.post(att, $(form).serialize() ).done(function (data) {
alert(data);
});
return true;
}
Additionally, You can use .serialize()
Check out curljson
$ pip install curljson
$ curljson -i <the-json-api-url>
Just set noHistory="true"
in Manifest file.
It makes activity being removed from the backstack.
This worked for me,
1. For getting Columns having at least 1 null value. (column names)
data.columns[data.isnull().any()]
2. For getting Columns with count, with having at least 1 null value.
data[data.columns[data.isnull().any()]].isnull().sum()
[Optional] 3. For getting percentage of the null count.
data[data.columns[data.isnull().any()]].isnull().sum() * 100 / data.shape[0]
Their names can be a bit confusing :). Here's a summary:
The SelectedItem property returns the entire object that your list is bound to. So say you've bound a list to a collection of Category
objects (with each Category object having Name and ID properties). eg. ObservableCollection<Category>
. The SelectedItem
property will return you the currently selected Category
object. For binding purposes however, this is not always what you want, as this only enables you to bind an entire Category object to the property that the list is bound to, not the value of a single property on that Category object (such as its ID
property).
Therefore we have the SelectedValuePath property and the SelectedValue property as an alternative means of binding (you use them in conjunction with one another). Let's say you have a Product
object, that your view is bound to (with properties for things like ProductName, Weight, etc). Let's also say you have a CategoryID
property on that Product object, and you want the user to be able to select a category for the product from a list of categories. You need the ID property of the Category object to be assigned to the CategoryID
property on the Product object. This is where the SelectedValuePath
and the SelectedValue
properties come in. You specify that the ID property on the Category object should be assigned to the property on the Product object that the list is bound to using SelectedValuePath='ID'
, and then bind the SelectedValue
property to the property on the DataContext (ie. the Product).
The example below demonstrates this. We have a ComboBox bound to a list of Categories (via ItemsSource). We're binding the CategoryID property on the Product as the selected value (using the SelectedValue property). We're relating this to the Category's ID property via the SelectedValuePath property. And we're saying only display the Name property in the ComboBox, with the DisplayMemberPath property).
<ComboBox ItemsSource="{Binding Categories}"
SelectedValue="{Binding CategoryID, Mode=TwoWay}"
SelectedValuePath="ID"
DisplayMemberPath="Name" />
public class Category
{
public int ID { get; set; }
public string Name { get; set; }
}
public class Product
{
public int CategoryID { get; set; }
}
It's a little confusing initially, but hopefully this makes it a bit clearer... :)

This approach requires jQuery. First, select your iframe:
var yourIframe = $('iframe#yourId');
//yourId or something to select your iframe.
Now you select button play/pause of this iframe and click it
$('button.ytp-play-button.ytp-button', yourIframe).click();
I hope it will help you.
The attribute packed
means that the compiler will not add padding between fields of the struct
. Padding is usually used to make fields aligned to their natural size, because some architectures impose penalties for unaligned access or don't allow it at all.
aligned(4)
means that the struct should be aligned to an address that is divisible by 4.
Since jQuery AJAX requests fail if they are cross-domain, you can use cURL (in PHP) to set up a proxy server.
Suppose a PHP file responder.php has these contents:
$url = "https://www.google.com";
$ch = curl_init( $url );
curl_set_opt($ch, CURLOPT_RETURNTRANSFER, "true")
$response= curl_exec( $ch );
curl_close( $ch );
return $response;
Your AJAX request should be to this responder.php file so that it executes the cross-domain request.
return false;
at the end of the onclick handler will do the job. However, it's be better to simply add type="button"
to the <button>
- that way it behaves properly even without any JavaScript.
Jonas's answer does not change the font size of the axes. Sergeyf's answer does not work when there are multiple subplots.

You need to call srand()
once, to randomize the seed, and then call rand()
in your loop:
#include <stdlib.h>
#include <time.h>
#define size 10
srand(time(NULL)); // randomize seed
for(i=0;i<size;i++)
Arr[i] = rand()%size;
From @sidharth: "caused my lava iris alfa to go into a bootloop :("
For my Motorola Nexus 6 running Android Marshmallow 6.0.1 I did:
adb devices # Check the phone is running
adb reboot bootloader
# Wait a few seconds
fastboot devices # Check the phone is in bootloader
fastboot -w # Wipe user data
The approach I used when faced with this problem was to add the signer of the temporary certificate to the trusted authorities list on the computer in question.
I normally do testing with certificates created with CACERT, and adding them to my trusted authorities list worked swimmingly.
Doing it this way means you don't have to add any custom code to your application and it properly simulates what will happen when your application is deployed. As such, I think this is a superior solution to turning off the check programmatically.
Many thanks for this guys.
I mangaged to get this down to one line:
var results = from p in People
where !(from e in exclusions
select e.CompositeKey).Contains(p.CompositeKey)
select p;
Thanks again everyone.
To use base_url()
(shorthand), you have to load the URL Helper
first
$this->load->helper('url');
Or you can autoload it by changing application/config/autoload.php
Or just use
$this->config->base_url();
Same applies to site_url()
.
Also I can see you are missing echo
(though its not your current problem), use the code below to solve the problem
<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />
Take IISReset as a suite of commands that helps you manage IIS start / stop etc.
Which means you need to specify option (/switch
) what you want to do to carry any operation.
Default behavior OR default switch is /restart
with iisreset
so you do not need to run command twice with /start
and /stop
.
Hope this clarifies your question. For reference the output of iisreset /?
is:
IISRESET.EXE (c) Microsoft Corp. 1998-2005 Usage: iisreset [computername] /RESTART Stop and then restart all Internet services. /START Start all Internet services. /STOP Stop all Internet services. /REBOOT Reboot the computer. /REBOOTONERROR Reboot the computer if an error occurs when starting, stopping, or restarting Internet services. /NOFORCE Do not forcefully terminate Internet services if attempting to stop them gracefully fails. /TIMEOUT:val Specify the timeout value ( in seconds ) to wait for a successful stop of Internet services. On expiration of this timeout the computer can be rebooted if the /REBOOTONERROR parameter is specified. The default value is 20s for restart, 60s for stop, and 0s for reboot. /STATUS Display the status of all Internet services. /ENABLE Enable restarting of Internet Services on the local system. /DISABLE Disable restarting of Internet Services on the local system.

Try declaring the unit of width:

I'm not sure when this was written, but currently to add or remove a default from a column in a migration, you can use the following:
change_column_null :products, :name, false
Rails 5:
change_column_default :products, :approved, from: true, to: false
http://edgeguides.rubyonrails.org/active_record_migrations.html#changing-columns
Rails 4.2:
change_column_default :products, :approved, false
http://guides.rubyonrails.org/v4.2/active_record_migrations.html#changing-columns
Which is a neat way of avoiding looking through your migrations or schema for the column specifications.

Try to check the length of the selector, if it returns you something then the element must exists else not.

{
// it exists
}
This is the full step-by-step procedure to resync a master-slave replication from scratch:
At the master:
RESET MASTER;
FLUSH TABLES WITH READ LOCK;
SHOW MASTER STATUS;
And copy the values of the result of the last command somewhere.
Without closing the connection to the client (because it would release the read lock) issue the command to get a dump of the master:
mysqldump -u root -p --all-databases > /a/path/mysqldump.sql
Now you can release the lock, even if the dump hasn't ended yet. To do it, perform the following command in the MySQL client:
UNLOCK TABLES;
Now copy the dump file to the slave using scp or your preferred tool.
At the slave:
Open a connection to mysql and type:
STOP SLAVE;
Load master's data dump with this console command:
mysql -uroot -p < mysqldump.sql
Sync slave and master logs:
RESET SLAVE;
CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=98;
Where the values of the above fields are the ones you copied before.
Finally, type:
START SLAVE;
To check that everything is working again, after typing:
SHOW SLAVE STATUS;
you should see:
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
That's it!

You don't need to use only identifier as elements locators. You can use a few ways to find an element. Read this article and choose the best for you.
The Saxon documentation, though a little unclear, seems to suggest that the JAXP XPath API will return false
when evaluating an XPath expression if no matching nodes are found.
This IBM article mentions a return value of null
when no nodes are matched.
You might need to play around with the return types a bit based on this API, but the basic idea is that you just run a normal XPath and check whether the result is a node / false
/ null
/ etc.
XPathFactory xpathFactory = XPathFactory.newInstance(NamespaceConstant.OBJECT_MODEL_SAXON);
XPath xpath = xpathFactory.newXPath();
XPathExpression expr = xpath.compile("/Consumers/Consumer/DataSources/Credit/CreditReport/AttachedXml");
Object result = expr.evaluate(doc, XPathConstants.NODE);
if ( result == null ) {
// do something
}
Use the below query to store the result in a CSV file
\copy (your query) to 'file path' csv header;
Example
\copy (select name,date_order from purchase_order) to '/home/ankit/Desktop/result.csv' cvs header;
Hope this helps you.

You can't slice a generator directly in Python. itertools.islice()
will wrap an object in a new slicing generator using the syntax itertools.islice(generator, start, stop, step)
Remember, slicing a generator will exhaust it partially. If you want to keep the entire generator intact, perhaps turn it into a tuple or list first, like: result = tuple(generator)
I know this is an old question, but I just wanted to post this bit of code as I could not find a simple gem to do just this task for me.
module QueryParams
def self.encode(value, key = nil)
case value
when Hash then value.map { |k,v| encode(v, append_key(key,k)) }.join('&')
when Array then value.map { |v| encode(v, "#{key}[]") }.join('&')
when nil then ''
else
"#{key}=#{CGI.escape(value.to_s)}"
end
end
private
def self.append_key(root_key, key)
root_key.nil? ? key : "#{root_key}[#{key.to_s}]"
end
end
Rolled up as gem here: https://github.com/simen/queryparams
You can use a list comprehension to filter it:
j2 = [i for i in j if i >= 5]
If you actually want it sorted like your example was, you can use sorted
:
j2 = sorted(i for i in j if i >= 5)
or call sort
on the final list:
j2 = [i for i in j if i >= 5]
j2.sort()
If you're using another utility that passes a single argument to grep, you can use:
'[-]X'
You can use the RANK function in Excel without necessarily sorting the data. Type =RANK(C2,$C$2:$C$7). Excel will find the relative position of the data in C2 and display the answer. Copy the formula through to C7 by dragging the small node at the right end of the cell cursor.

As you move the window bar, you'll see iframe to responsively resize
Alternatively, you may also use the intrinsic ratio technique - This is just an alternate option of the same solution above (tomato, tomato)
.iframe-container {
overflow: hidden;
padding-top: 56.25%;
position: relative;
}
.iframe-container iframe {
position: absolute;

}
Adding display:inline-block
to the labels and giving them padding-top
would fix this, I think. Also, just setting the line-height
on the labels would also.

You should be pointing it towards the Developer
directory, not the Xcode application bundle. Run this:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.
Try this:
concat(left(datefield,10),left(timefield,8))
10 char on date field based on full date yyyy-MM-dd
.
8 char on time field based on full time hh:mm:ss
.
It depends on the format you want it. normally you can use script above and you can concat another field or string as you want it.
Because actually date and time field tread as string if you read it. But of course you will got error while update or insert it.
No need to use .each

$window.location.reload();
What you may want to do is include a script on all pages that does the following ... 1. find the youtube-iframe : searching for it by width and height by title or by finding www.youtube.com in its source. You can do that by ... - looping through the window.frames by a for-in loop and then filter out by the properties
inject jscript in the iframe of the current page adding the onYoutubePlayerReady must-include-function http://shazwazza.com/post/Injecting-JavaScript-into-other-frames.aspx

If it helps, I was using centrifuge with my reactjs app, and, after checking some comments below, I looked at the centrifuge.js library file, which in my version, had the following code snippet:
if ('withCredentials' in xhr) {
xhr.withCredentials = true;
}
After I removed these three lines, the app worked fine, as expected.
Hope it helps!
The root cause of this issue can be in the regional settings - DB waiting for YYYY-MM-DD while an app sents, for example, DD-MM-YYYY (Russian locale format) as it was in my case. All I did - change locale format from Russian to English (United States) and voilà.

Xamarin.Forms
supports multiple navigation hosts built-in:
NavigationPage
, where the next page slide in,TabbedPage
, the one you don't likeCarouselPage
, that allows for switching left and right to next/prev pages.On top of this, all pages also supports PushModalAsync()
which just push a new page on top of the existing one.
At the very end, if you want to make sure the user can't get back to the previous page (using a gesture or the back hardware button), you can keep the same Page
displayed and replace its Content
.
The suggested options of replacing the root page works as well, but you'll have to handle that differently for each platform.

In simpler words:
key=
parameter of sort
requires a key function (to be applied to be objects to be sorted) rather than a single key value and operator.itemgetter(1)
will give you: A function that grabs the first item from a list-like object. (More precisely those are callables, not functions, but that is a difference that can often be ignored.)
The syntax is:
cd /path/to/dir
grep -r <"serch_word name"> .
By the time the query gets to SQL you have to have already expanded the list. The easy way of doing this, if you're using IDs from some internal, trusted data source, where you can be 100% certain they're integers (e.g., if you selected them from your database earlier) is this:
$sql = 'SELECT * WHERE id IN (' . implode(',', $ids) . ')';
If your data are coming from the user, though, you'll need to ensure you're getting only integer values, perhaps most easily like so:
$sql = 'SELECT * WHERE id IN (' . implode(',', array_map('intval', $ids)) . ')';
I set the PHPRC variable and uncommented zend_extension=php_opcache.dll

Using dotPeek helps to see how the framework actually does it. With that in mind, here's what I've come up with:
public static class EnvironmentHelper
{
[DllImport("kernel32.dll")]
static extern IntPtr GetCurrentProcess();
[DllImport("kernel32.dll")]
static extern IntPtr GetModuleHandle(string moduleName);
[DllImport("kernel32")]
static extern IntPtr GetProcAddress(IntPtr hModule, string procName);
[DllImport("kernel32.dll")]
static extern bool IsWow64Process(IntPtr hProcess, out bool wow64Process);
public static bool Is64BitOperatingSystem()
{
// Check if this process is natively an x64 process. If it is, it will only run on x64 environments, thus, the environment must be x64.
if (IntPtr.Size == 8)
return true;
// Check if this process is an x86 process running on an x64 environment.
IntPtr moduleHandle = GetModuleHandle("kernel32");
if (moduleHandle != IntPtr.Zero)
{
IntPtr processAddress = GetProcAddress(moduleHandle, "IsWow64Process");
if (processAddress != IntPtr.Zero)
{
bool result;
if (IsWow64Process(GetCurrentProcess(), out result) && result)
return true;
}
}
// The environment must be an x86 environment.
return false;
}
}
Example usage:
EnvironmentHelper.Is64BitOperatingSystem();

The first answer was great, but I had to add try/catch to avoid Java compiler errors.
Also, I had troubles to figure how to read the HttpResponse
with Java libraries.
Here is the more complete code :
/*
* Create the POST request
*/
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://example.com/");
// Request parameters and other properties.
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("user", "Bob"));
try {
httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
} catch (UnsupportedEncodingException e) {
// writing error to Log
e.printStackTrace();
}
/*
* Execute the HTTP Request
*/
try {
HttpResponse response = httpClient.execute(httpPost);
HttpEntity respEntity = response.getEntity();
if (respEntity != null) {
// EntityUtils to get the response content
String content = EntityUtils.toString(respEntity);
}
} catch (ClientProtocolException e) {
// writing exception to log
e.printStackTrace();
} catch (IOException e) {
// writing exception to log
e.printStackTrace();
}
In case entire entity is being return, better solution in spring JPA is use @Query(value = "from entity where Id in :ids")
This return entity type rather than object type
MySQL Workbench
If you want to avoid writing sql, you can also do it in MySQL Workbench by right clicking on the table, choose "Alter Table ..." in the menu.
When the table structure view opens, go to tab "Options" (on the lower bottom of the view), and set "Auto Increment" field to the value of the next autoincrement number.
Don't forget to hit "Apply" when you are done with all changes.
PhpMyAdmin:
If you are using phpMyAdmin, you can click on the table in the lefthand navigation, go to the tab "Operations" and under Table Options change the AUTO_INCREMENT value and click OK.

Well, In my applications I just need to Add a reference to "DocumentFormat.OpenXml" under .Net tab and both references (DocumentFormat.OpenXml and WindowsBase) are always added automatically. But They are not included within the Bin folder. So when the Application is published to an external server I always place DocumentFormat.OpenXml.dll under the Bin folder manually. Or set the reference "Copy Local" property to true.

Couldn't be more simple can it ?
printf
accepts a variable number of arguments. Those can only have Plain Old Data (POD) types. Code that passes anything other than POD to printf
only compiles because the compiler assumes you got your format right. %s
means that the respective argument is supposed to be a pointer to a char
. In your case it is an std::string
not const char*
. printf
does not know it because the argument type goes lost and is supposed to be restored from the format parameter. When turning that std::string
argument into const char*
the resulting pointer will point to some irrelevant region of memory instead of your desired C string. For that reason your code prints out gibberish.
While printf
is an excellent choice for printing out formatted text, (especially if you intend to have padding), it can be dangerous if you haven't enabled compiler warnings. Always enable warnings because then mistakes like this are easily avoidable. There is no reason to use the clumsy std::cout
mechanism if the printf
family can do the same task in a much faster and prettier way. Just make sure you have enabled all warnings (-Wall -Wextra
) and you will be good. In case you use your own custom printf
implementation you should declare it with the __attribute__
mechanism that enables the compiler to check the format string against the parameters provided.
I am not sure I understood your question, but if you write:
mask_data[:3, :3] = 1
mask_data[3:, 3:] = 0
This will make all values of mask data whose x and y indexes are less than 3 to be equal to 1 and all rest to be equal to 0
Just came across this problem myself, and the only solution I could find that worked in all my test browsers (IE6, IE7, Firefox) was the following:
The code:
<div style="width: 100%">
<div style="padding-right: 6px;">
<input type="text" style="width: 100%; padding: 2px; margin: 0;
border : solid 1px #999" />
</div>
</div>
Here, the total horizontal overflow for the input element is 6px - 2x(padding + border) - so we set a padding-right for the inner DIV of 6px.
To show more than one inputs inline without using "form-inline" class you can use the next code:
<div class="input-group">
<input type="text" class="form-control" value="First input" />
<span class="input-group-btn"></span>
<input type="text" class="form-control" value="Second input" />
</div>
Then using CSS selectors:
/* To remove space between text inputs */
.input-group > .input-group-btn:empty {
width: 0px;
}
Basically you have to insert an empty span tag with "input-group-btn" class between input tags.
If you want to see more examples of input groups and bootstrap-select groups take a look at this URL: http://jsfiddle.net/vkhusnulina/gze0Lcm0
Quick example using company1
from your question, with python3.
import pickle
# Save the file
pickle.dump(company1, file = open("company1.pickle", "wb"))
# Reload the file
company1_reloaded = pickle.load(open("company1.pickle", "rb"))
However, as this answer noted, pickle often fails. So you should really use dill
.
import dill
# Save the file
dill.dump(company1, file = open("company1.pickle", "wb"))
# Reload the file
company1_reloaded = dill.load(open("company1.pickle", "rb"))

Without knowing more about the problem domain, it's hard to answer your question. Unless you are certain that you need to do something more, the pythonic way to initialize a list is:
verts = []
Are you actually seeing a performance problem? If so, what is the performance bottleneck? Don't try to solve a problem that you don't have. It's likely that performance cost to dynamically fill an array to 1000 elements is completely irrelevant to the program that you're really trying to write.
The array class is useful if the things in your list are always going to be a specific primitive fixed-length type (e.g. char, int, float). But, it doesn't require pre-initialization either.
If you want add a day (24 hours) to current datetime you can add milliseconds like this:
new Date(Date.now() + ( 3600 * 1000 * 24))
According to The W3C:
This attribute sets the size of the font. Possible values:
- An integer between 1 and 7. This sets the font to some fixed size, whose rendering depends on the user agent. Not all user agents may render all seven sizes.
- A relative increase in font size. The value "+1" means one size larger. The value "-3" means three sizes smaller. All sizes belong to the scale of 1 to 7.
Hence, the conversion you're asking for is not possible. The browser is not required to use specific sizes with specific size
attributes.
Also note that use of the font
element is discouraged by W3 in favor of style sheets.
NULL
isn't a native part of the core C++ language, but it is part of the standard library. You need to include one of the standard header files that include its definition. #include <cstddef>
or #include <stddef.h>
should be sufficient.
The definition of NULL
is guaranteed to be available if you include cstddef
or stddef.h
. It's not guaranteed, but you are very likely to get its definition included if you include many of the other standard headers instead.
The published responses are correct but incomplete.
Git to install the packages we first need to make sure git is installed.
$ sudo apt install git-core
Bower uses Node.js and npm to manage the programs so lets install these.
$ sudo apt install nodejs
Node will now be installed with the executable located in /etc/usr/nodejs
.
You should be able to execute Node.js by using the command below, but as ours are location in nodejs we will get an error No such file or directory.
$ /usr/bin/env node
We can manually fix this by creating a symlink.
$ sudo ln -s /usr/bin/nodejs /usr/bin/node
Now check Node.js is installed correctly by using.
$ /usr/bin/env node
>
Some users suggest installing legacy nodejs, this package just creates a symbolic link to binary nodejs.
$ sudo apt install nodejs-legacy
Now, you can install npm and bower
Install npm
$ sudo apt install npm
Install Bower
$ sudo npm install -g bower
Check bower is installed and what version you're running.
$ bower -v
1.8.0
Reference:
well, why don't you (get rid of sidebar and) squeeze the table so it is without show/hide effect? It looks odd to me now. The table is too robust.
Otherwise I think scunliffe's suggestion should do it. Or if you wish, you can just set the exact width of table and set either percentage or pixel width for table cells.
As someone who has worked with ASP.NET API for about 3 years, I'd recommend returning an HttpResponseMessage instead. Don't use the ActionResult or IEnumerable!
ActionResult is bad because as you've discovered.
Return IEnumerable<> is bad because you may want to extend it later and add some headers, etc.
Using JsonResult is bad because you should allow your service to be extendable and support other response formats as well just in case in the future; if you seriously want to limit it you can do so using Action Attributes, not in the action body.
public HttpResponseMessage GetAllNotificationSettings()
{
var result = new List<ListItems>();
// Filling the list with data here...
// Then I return the list
return Request.CreateResponse(HttpStatusCode.OK, result);
}
In my tests, I usually use the below helper method to extract my objects from the HttpResponseMessage:
public class ResponseResultExtractor
{
public T Extract<T>(HttpResponseMessage response)
{
return response.Content.ReadAsAsync<T>().Result;
}
}
var actual = ResponseResultExtractor.Extract<List<ListItems>>(response);
In this way, you've achieved the below:
Look at this: http://www.asp.net/web-api/overview/formats-and-model-binding/content-negotiation
How about you store it like this? Maybe in username:password format, so
sebastion:password123
anotheruser:password321
Then you can use list($username,$password) = explode(':',file_get_contents('users.txt'));
to parse the data on your end.
I had the similar problem and solved it by doing following.

Late to the party, but if you don't want to expose environment variables, I guess it's easier to do something like this:
RUN echo 1 > /tmp/__var_1
RUN echo `cat /tmp/__var_1`
RUN rm -f /tmp/__var_1
I ended up doing it because we host private npm packages in aws codeartifact:
RUN aws codeartifact get-authorization-token --output text > /tmp/codeartifact.token
RUN npm config set //company-123456.d.codeartifact.us-east-2.amazonaws.com/npm/internal/:_authToken=`cat /tmp/codeartifact.token`
RUN rm -f /tmp/codeartifact.token
And here ARG
cannot work and i don't want to use ENV
because i don't want to expose this token to anything else
So I had the same issue, but it was because I was saving the access token but not using it. It could be because I'm super sleepy because of due dates, or maybe I just didn't think about it! But in case anyone else is in the same situation:
When I log in the user I save the access token:
$facebook = new Facebook(array(
'appId' => <insert the app id you get from facebook here>,
'secret' => <insert the app secret you get from facebook here>
));
$accessToken = $facebook->getAccessToken();
//save the access token for later
Now when I make requests to facebook I just do something like this:
$facebook = new Facebook(array(
'appId' => <insert the app id you get from facebook here>,
'secret' => <insert the app secret you get from facebook here>
));
$facebook->setAccessToken($accessToken);
$facebook->api(... insert own code here ...)
Besides the solutions presented already, you could use the Apache Commons Lang library:
if(StringUtils.startsWithAny(newStr4, new String[] {"Mon","Tues",...})) {
//whatever
}
Update: the introduction of varargs at some point makes the call simpler now:
StringUtils.startsWithAny(newStr4, "Mon", "Tues",...)

{
innerTableColumns.Add(column.ColumnName);
resultTable.Columns.Add(column.ColumnName);
}
var outerTableColumns = new List<string>();
foreach (DataColumn column in outerTable.Columns)
{
if (!innerTableColumns.Contains(column.ColumnName))
{
outerTableColumns.Add(column.ColumnName);
resultTable.Columns.Add(column.ColumnName);
}
}
for (int i = 0; i < innerTable.Rows.Count; i++)
{
var row = resultTable.NewRow();
innerTableColumns.ForEach(x =>
{
row[x] = innerTable.Rows[i][x];
});
outerTableColumns.ForEach(x =>
{
row[x] = outerTable.Rows[i][x];
});
resultTable.Rows.Add(row);
}
return resultTable;
}
The error you quote has nothing to do with pg_hba.conf
; it's failing to connect, not failing to authorize the connection.
Do what the error message says:
Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections
You haven't shown the command that produces the error. Assuming you're connecting on localhost
port 5432
(the defaults for a standard PostgreSQL install), then either:
PostgreSQL isn't running
PostgreSQL isn't listening for TCP/IP connections (listen_addresses
in postgresql.conf
)
PostgreSQL is only listening on IPv4 (0.0.0.0
or 127.0.0.1
) and you're connecting on IPv6 (::1
) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.
PostgreSQL is listening on a different port to the one you're connecting on
(unlikely) there's an iptables
rule blocking loopback connections
(If you are not connecting on localhost
, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).
So ... check those:
ps -f -u postgres
should list postgres
processes
sudo lsof -n -u postgres |grep LISTEN
or sudo netstat -ltnp | grep postgres
should show the TCP/IP addresses and ports PostgreSQL is listening on
BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:
$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 12345?
All the answers here are great but, just to illustrate where this comes from, for questions like this it's good to go to the source: the Java Language Specification.
Section 15:23, Conditional-And operator (&&), says:
The && operator is like & (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is true. [...] At run time, the left-hand operand expression is evaluated first [...] if the resulting value is false, the value of the conditional-and expression is false and the right-hand operand expression is not evaluated. If the value of the left-hand operand is true, then the right-hand expression is evaluated [...] the resulting value becomes the value of the conditional-and expression. Thus, && computes the same result as & on boolean operands. It differs only in that the right-hand operand expression is evaluated conditionally rather than always.
And similarly, Section 15:24, Conditional-Or operator (||), says:
The || operator is like | (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is false. [...] At run time, the left-hand operand expression is evaluated first; [...] if the resulting value is true, the value of the conditional-or expression is true and the right-hand operand expression is not evaluated. If the value of the left-hand operand is false, then the right-hand expression is evaluated; [...] the resulting value becomes the value of the conditional-or expression. Thus, || computes the same result as | on boolean or Boolean operands. It differs only in that the right-hand operand expression is evaluated conditionally rather than always.
A little repetitive, maybe, but the best confirmation of exactly how they work. Similarly the conditional operator (?:) only evaluates the appropriate 'half' (left half if the value is true, right half if it's false), allowing the use of expressions like:
int x = (y == null) ? 0 : y.getFoo();
without a NullPointerException.

One more way:
git diff stash@{N}^! -- path/to/file1 path/to/file2 | git apply -R
Use os.path.normpath
, then os.path.basename
:
>>> os.path.basename(os.path.normpath('/folderA/folderB/folderC/folderD/'))
'folderD'
The first strips off any trailing slashes, the second gives you the last part of the path. Using only basename
gives everything after the last slash, which in this case is ''
.

You have asked two questions, one in the title about the difference between PNG8 and PNG24, which has received a few answers, namely that PNG24 has 8-bit red, green, and blue channels, and PNG-8 has a single 8-bit index into a palette. Naturally, PNG24 usually has a larger filesize than PNG8. Furthermore, PNG8 usually means that it is opaque or has only binary transparency (like GIF); it's defined that way in ImageMagick/GraphicsMagick.
This is an answer to the other one, "I would like to know that if I use either type in my html page, will there be any error? Or is this only quality matter?"
You can put either type on an HTML page and no, this won't cause an error; the files should all be named with the ".png" extension and referred to that way in your HTML. Years ago, early versions of Internet Explorer would not handle PNG with an alpha channel (PNG32) or indexed-color PNG with translucent pixels properly, so it was useful to convert such images to PNG8 (indexed-color with binary transparency conveyed via a PNG tRNS chunk) -- but still use the .png extension, to be sure they would display properly on IE. I think PNG24 was always OK on Internet Explorer because PNG24 is either opaque or has GIF-like single-color transparency conveyed via a PNG tRNS chunk.
The names PNG8 and PNG24 aren't mentioned in the PNG specification, which simply calls them all "PNG". Other names, invented by others, include
There are many more possible combinations including grayscale with 1, 2, 4, 8, or 16-bit samples and indexed PNG with 1, 2, or 4-bit samples (and any of those with transparent or translucent pixels), but those don't have special names.
This is how I toggle two div
s at the same time:
$('#login-form, #recover-password').toggle();
It works!
That's still a constant. See the JLS for more information regarding the naming convention for constants. But in reality, it's all a matter of preference.
The names of constants in interface types should be, and
final
variables of class types may conventionally be, a sequence of one or more words, acronyms, or abbreviations, all uppercase, with components separated by underscore"_"
characters. Constant names should be descriptive and not unnecessarily abbreviated. Conventionally they may be any appropriate part of speech. Examples of names for constants includeMIN_VALUE
,MAX_VALUE
,MIN_RADIX
, andMAX_RADIX
of the classCharacter
.A group of constants that represent alternative values of a set, or, less frequently, masking bits in an integer value, are sometimes usefully specified with a common acronym as a name prefix, as in:
interface ProcessStates { int PS_RUNNING = 0; int PS_SUSPENDED = 1; }
Obscuring involving constant names is rare:
- Constant names normally have no lowercase letters, so they will not normally obscure names of packages or types, nor will they normally shadow fields, whose names typically contain at least one lowercase letter.
- Constant names cannot obscure method names, because they are distinguished syntactically.
Yep, confirmed that simply using hh instead of HH fixed my issue.
Changed from this:
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm aa");
To this:
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm aa");
You can still use HH to store the time if you don't want to bother storing and dealing with the AM/PM. Then when you retrieve it, use hh.
I think that's what you're looking for:
SELECT CASE WHEN BoolField05 = 1 THEN Status ELSE 'DELETED' END AS MyStatus, t1.*
FROM WorkItems t1
WHERE (TextField01, TimeStamp) IN(
SELECT TextField01, MAX(TimeStamp)
FROM WorkItems t2
GROUP BY t2.TextField01
)
AND TimeStamp > '2009-02-12 18:00:00'
If you're in Oracle or in MS SQL 2005 and above, then you could do:
SELECT *
FROM (
SELECT CASE WHEN BoolField05 = 1 THEN Status ELSE 'DELETED' END AS MyStatus, t1.*,
ROW_NUMBER() OVER (PARTITION BY TextField01 ORDER BY TimeStamp DESC) AS rn
FROM WorkItems t1
) to
WHERE rn = 1
, it's more efficient.
If you are running the correct class and the main is properly defined, also check if you have a class called String defined in the same package. This definition of String class will be considered and since it doesn't confirm to main(java.lang.String[] args)
, you will get the same exception.
Suggestion is to never hide library java classes in your package.

SDK represents to software development kit, and IDE represents to integrated development environment. The IDE is the software or the program is used to write, compile, run, and debug such as Xcode. The SDK is the underlying engine of the IDE, includes all the platform's libraries an app needs to access. It's more basic than an IDE because it doesn't usually have graphical tools.
You don't require broadcast receiver. If one would take some pain copy one of the api(serviceconnection) from above example by Stephen Donecker and paste it in google you would get this, https://www.concretepage.com/android/android-local-bound-service-example-with-binder-and-serviceconnection
There is an excellent book about the topic:
http://www.amazon.com/Texturing-Modeling-Third-Procedural-Approach/dp/1558608486
It is biased toward non-real-time visual effects and animation generation, but the theory and ideas are usable outside of these fields, I suppose.
It may also worth to mention that there is a professional software package that implements a complete procedural workflow called SideFX's Houdini. You can use it to invent and prototype procedural solutions to problems, that you can later translate to code.
While it's a rather expensive package, it has a free evaluation licence, which can be used as a very nice educational and/or engineering tool.
The limit for the length of a command line is not imposed by the shell, but by the operating system. This limit is usually in the range of hundred kilobytes. POSIX denotes this limit ARG_MAX
and on POSIX conformant systems you can query it with
$ getconf ARG_MAX # Get argument limit in bytes
E.g. on Cygwin this is 32000, and on the different BSDs and Linux systems I use it is anywhere from 131072 to 2621440.
If you need to process a list of files exceeding this limit, you might want to look at the xargs
utility, which calls a program repeatedly with a subset of arguments not exceeding ARG_MAX
.
To answer your specific question, yes, it is possible to attempt to run a command with too long an argument list. The shell will error with a message along "argument list too long".
Note that the input to a program (as read on stdin or any other file descriptor) is not limited (only by available program resources). So if your shell script reads a string into a variable, you are not restricted by ARG_MAX
. The restriction also does not apply to shell-builtins.
According to SQL2000 help, sp_spaceused includes data and indexes.
This script should do:
CREATE TABLE #t (name SYSNAME, rows CHAR(11), reserved VARCHAR(18),
data VARCHAR(18), index_size VARCHAR(18), unused VARCHAR(18))
EXEC sp_msforeachtable 'INSERT INTO #t EXEC sp_spaceused ''?'''
-- SELECT * FROM #t ORDER BY name
-- SELECT name, CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3)) FROM #t ORDER BY name
SELECT SUM(CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3))) FROM #t
DROP TABLE #t
If the user name that is in the connection string has access to more then one database you have to specify the database you want the connection string to connect to. If your user has only one database available then you are correct that it doesn't matter. But it is good practice to put this in your connection string.
The List
interface supports random access via the get
method - to get line 0, use list.get(0)
. You'll need to use array access on that, ie, lines.get(0)[0]
is the first element of the first line.
See the javadoc here.
This works similar to Array.splice
:
String.prototype.splice = function (i, j, str) {
return this.substr(0, i) + str + this.substr(j, this.length);
};
And this option?
list_name<-list()
for(i in 1:100){
paste("orca",i,sep="")->list_name[[i]]
}
It works perfectly. In the example you put, first line is missing, and then gives you the error message.
The answers seems a bit over complicated. I hope I didn't misunderstand the question.
If you simply want to open a fancy box from a click to an "A" tag. Just set your html to
<a id="my_fancybox" href="#contentdiv">click me</a>
The contents of your box will be inside of a div with id "contentdiv" and in your javascript you can initialize fancybox like this:
$('#my_fancybox').fancybox({
'autoScale': true,
'transitionIn': 'elastic',
'transitionOut': 'elastic',
'speedIn': 500,
'speedOut': 300,
'autoDimensions': true,
'centerOnScroll': true,
});
This will show a fancybox containing "contentdiv" when your anchor tag is clicked.
UPDATE: I had some time on my hands, so ... I went ahead and fleshed out this idea. See below for the code.
Here's a bit of a crazy answer:
You could do what you're looking for -- essentially treat a two-dimensional array as a table with rows -- by writing a static method (perhaps an extension method) that takes a T[,]
and returns an IEnumerable<T[]>
. This would require copying each "row" of the underlying table into a new array, though.
A perhaps better (though more involved) approach would be to actually write a class that implements IList<T>
as a wrapper around a single "row" of a two-dimensional array (you would probably set IsReadOnly
to true and just implement the getter for the this[int]
property and probably Count
and GetEnumerator
; everything else could throw a NotSupportedException
). Then your static/extension method could return an IEnumerable<IList<T>>
and provide deferred execution.
That way you could write code pretty much like what you have:
foreach (IList<string> row in table.GetRows()) // or something
{
Console.WriteLine(row[0] + " " + row[1]);
}
Just a thought.
Implementation suggestion:
public static class ArrayTableHelper {
public static IEnumerable<IList<T>> GetRows<T>(this T[,] table) {
for (int i = 0; i < table.GetLength(0); ++i)
yield return new ArrayTableRow<T>(table, i);
}
private class ArrayTableRow<T> : IList<T> {
private readonly T[,] _table;
private readonly int _count;
private readonly int _rowIndex;
public ArrayTableRow(T[,] table, int rowIndex) {
if (table == null)
throw new ArgumentNullException("table");
if (rowIndex < 0 || rowIndex >= table.GetLength(0))
throw new ArgumentOutOfRangeException("rowIndex");
_table = table;
_count = _table.GetLength(1);
_rowIndex = rowIndex;
}
// I didn't implement the setter below,
// but you easily COULD (and then set IsReadOnly to false?)
public T this[int index] {
get { return _table[_rowIndex, index]; }
set { throw new NotImplementedException(); }
}
public int Count {
get { return _count; }
}
bool ICollection<T>.IsReadOnly {
get { return true; }
}
public IEnumerator<T> GetEnumerator() {
for (int i = 0; i < _count; ++i)
yield return this[i];
}
// omitted remaining IList<T> members for brevity;
// you actually could implement IndexOf, Contains, etc.
// quite easily, though
}
}
...now I think I should give StackOverflow a break for the rest of the day ;)
Or this will work too the same way but without a save as choice:
<!DOCTYPE html>
<html>
<head>
<script type='text/javascript'>//<![CDATA[
window.onload=function(){
(function () {
var textFile = null,
makeTextFile = function (text) {
var data = new Blob([text], {type: 'text/plain'});
// If we are replacing a previously generated file we need to
// manually revoke the object URL to avoid memory leaks.
if (textFile !== null) {
window.URL.revokeObjectURL(textFile);
}
textFile = window.URL.createObjectURL(data);
return textFile;
};
var create = document.getElementById('create'),
textbox = document.getElementById('textbox');
create.addEventListener('click', function () {
var link = document.getElementById('downloadlink');
link.href = makeTextFile(textbox.value);
link.style.display = 'block';
}, false);
})();
}//]]>
</script>
</head>
<body>
<textarea id="textbox">Type something here</textarea> <button id="create">Create file</button> <a download="info.txt" id="downloadlink" style="display: none">Download</a>
<script>
// tell the embed parent frame the height of the content
if (window.parent && window.parent.parent){
window.parent.parent.postMessage(["resultsFrame", {
height: document.body.getBoundingClientRect().height,
slug: "qm5AG"
}], "*")
}
</script>
</body>
</html>
Maybe You should try scrollIntoView.
document.getElementById('id').scrollIntoView();
This will scroll to your Element.
A bit more elaborate version (to use from another window):
#!/bin/bash
DELAY=3
TERM_PID=$(echo `ps -C gnome-terminal -o pid= | head -1`) # get first gnome-terminal's PID
WID=$(wmctrl -lp | awk -v pid=$TERM_PID '$3==pid{print $1;exit;}') # get window id
xdotool windowfocus $WID
xdotool key alt+t # my key map
xdotool sleep $DELAY # it may take a while to start new shell :(
xdotool type --delay 1 --clearmodifiers "$@"
xdotool key Return
wmctrl -i -a $WID # go to that window (WID is numeric)
# vim:ai
# EOF #
The pythonic way to track state during iteration is with generators. The itertools way is quite hard to understand IMHO and trying to hack lambdas to do this is plain silly. I'd try:
def keep_last_empty(input):
last = None
for item in iter(input):
if item.name: yield item
else: last = item
if last is not None: yield last
output = list(keep_last_empty(input))
Overall, readability trumps compactness every time.
The original syntax will work with BASH but not with DASH. On debian systems you might think you are using bash, but maybe dash instead. If /bin/dash/exist then try temporarily renaming dash to something like no.dash, and then create soft a link, aka ln -s /bin/bash /bin/dash and see if that fixes the problem.
These hints helped me with my Ubuntu 14.04 LTS install,
In addition I needed to turn on the short_open_tag
in /etc/php5/fpm/php.ini
$ sudo kate /etc/php5/fpm/php.ini
short_open_tag = On
$ sudo service php5-fpm restart
$ sudo service nginx reload

Steps:
1. Add accept attribute to input tag
2. Validate with javascript
3. Add server side validation to verify if the content is really an expected file type
For HTML and javascript:
<html>
<body>
<input name="image" type="file" id="fileName" accept=".jpg,.jpeg,.png" onchange="validateFileType()"/>
<script type="text/javascript">
function validateFileType(){
var fileName = document.getElementById("fileName").value;
var idxDot = fileName.lastIndexOf(".") + 1;
var extFile = fileName.substr(idxDot, fileName.length).toLowerCase();
if (extFile=="jpg" || extFile=="jpeg" || extFile=="png"){
//TO DO
}else{
alert("Only jpg/jpeg and png files are allowed!");
}

Explanation:
I restarted my computer and then opened the IDE again and it worked while none of the above did.
Maybe you have to do the things above as well, but make sure to restart the computer too.
Use the Git GUI in the Git plugin.
Clone your online repository with the URL which you have.
After cloning, make changes to the files. When you make changes, you can see the number changes. Commit those changes.
Fetch from the remote (to check if anything is updated while you are working).
If the fetch operation gives you an update about the changes in the remote repository, make a pull operation which will update your copy in Visual Studio Code. Otherwise, do not make a pull operation if there aren't any changes in the remote repository.
Push your changes to the upstream remote repository by making a push operation.
To go directly to that folder, you can use the Set-Location
cmdlet or cd
alias:
Set-Location "Q:\My Test Folder"
You can call max(vector, na.rm = TRUE)
. More generally, you can use the na.omit()
function.
I actually had a very similar challenge on my current project. That broght me to the idea of writing a small script which I called docker-compose-profile (or short: dcp). I published this today on GitLab as docker-compose-profile.
So in short: I now can start several predefined docker-compose profiles using a command like dcp -p some-services "up -d"
. Feel free to try it out and give some feedback or suggestions for further improvements.
The enumerate()
function adds a counter to an iterable.
So for each element in cursor
, a tuple is produced with (counter, element)
; the for
loop binds that to row_number
and row
, respectively.
Demo:
>>> elements = ('foo', 'bar', 'baz')
>>> for elem in elements:
... print elem
...
foo
bar
baz
>>> for count, elem in enumerate(elements):
... print count, elem
...
0 foo
1 bar
2 baz
By default, enumerate()
starts counting at 0
but if you give it a second integer argument, it'll start from that number instead:
>>> for count, elem in enumerate(elements, 42):
... print count, elem
...
42 foo
43 bar
44 baz
If you were to re-implement enumerate()
in Python, here are two ways of achieving that; one using itertools.count()
to do the counting, the other manually counting in a generator function:
from itertools import count
def enumerate(it, start=0):
# return an iterator that adds a counter to each element of it
return zip(count(start), it)
and
def enumerate(it, start=0):
count = start
for elem in it:
yield (count, elem)
count += 1
The actual implementation in C is closer to the latter, with optimisations to reuse a single tuple object for the common for i, ...
unpacking case and using a standard C integer value for the counter until the counter becomes too large to avoid using a Python integer object (which is unbounded).
The underlying issue is using max-device-width
vs plain old max-width
.
Using the "device" keyword targets physical dimension of the screen, not the width of the browser window.
For example:
@media only screen and (max-device-width: 480px) {
/* STYLES HERE for DEVICES with physical max-screen width of 480px */
}
Versus
@media only screen and (max-width: 480px) {
/* STYLES HERE for BROWSER WINDOWS with a max-width of 480px.
This will work on desktops when the window is narrowed. */
}
A small demo may help you: In abc.php file:
<script type="text/javascript">
$('<?php echo '#'.$selectCategory_row['subID']?>').on('switchChange.bootstrapSwitch', function(event, state) {
postState(state,'<?php echo $selectCategory_row['subID']?>');
});
</script>
Dim q = From c In TableA
Select c.TableA
ObjectDumper.Write(q)
install nvm (Node Version Manager) and downgrade node version from 14 to 12 solved the issue in my case
If you mean that both ProductName
fields are to have the same value, then:
SELECT a.ProductName,a.NumberofProducts,b.ProductName,b.NumberofProductsSold FROM Table1 a, Table2 b WHERE a.ProductName=b.ProductName;
Or, if you want the ProductName
column to be displayed only once,
SELECT a.ProductName,a.NumberofProducts,b.NumberofProductsSold FROM Table1 a, Table2 b WHERE a.ProductName=b.ProductName;
Otherwise,if any row of Table1 can be associated with any row from Table2 (even though I really wonder why anyone'd want to do that), you could give this a look.
Save a snapshot of the database into a dump.rdb by either running BGSAVE
or SAVE
from the command line. This will create a file named dump.rdb in the same folder as your redis server. See a list of all server commands.
Copy this dump.rdb to the other redis server you want to migrate to. When redis starts up, it looks for this file to initialize the database from.
for i, row in df.iterrows():
if <something>:
df.at[i, 'ifor'] = x
else:
df.at[i, 'ifor'] = y
My answer is a total hack- I just created a link that looks like a button and add the URL to that.
<a class="el-button"
style="color: white; background-color: #58B7FF;"
:href="<YOUR URL ENDPOINT HERE>"
:download="<FILE NAME NERE>">
<i class="fa fa-file-excel-o"></i> Excel
</a>
I'm using the excellent VueJs hence the odd anotations, however, this solution is framework agnostic. The idea would work for any HTML based design.
You could escape the % in %20 like so:
print "Hello%%20World%s" %"!"
or you could try using the string formatting routines instead, like:
print "Hello%20World{0}".format("!")
Once you have your image, you can use
$ docker tag <image> <newName>/<repoName>:<tagName>
Build and tag the image with creack/node:latest
$ ID=$(docker build -q -t creack/node .)
Add a new tag
$ docker tag $ID creack/node:0.10.24
You can use this and skip the -t part from build
$ docker tag $ID creack/node:latest
If you only need to display the images base on a tag, then there is not to include the wrapper class "instagram.class.php". As the Media & Tag Endpoints in Instagram API do not require authentication. You can use the following curl based function to retrieve results based on your tag.
function callInstagram($url)
{
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_SSL_VERIFYHOST => 2
));
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$tag = 'YOUR_TAG_HERE';
$client_id = "YOUR_CLIENT_ID";
$url = 'https://api.instagram.com/v1/tags/'.$tag.'/media/recent?client_id='.$client_id;
$inst_stream = callInstagram($url);
$results = json_decode($inst_stream, true);
//Now parse through the $results array to display your results...
foreach($results['data'] as $item){
$image_link = $item['images']['low_resolution']['url'];
echo '<img src="'.$image_link.'" />';
}
Semantic reasons aside, there is no vtable until after the object is constructed, thus making a virtual designation useless.
Just use in your if (key=="smk")
if (key=="smk") { window.open('http://www.smkproduction.eu5.org','_blank'); }
[tableview scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO];
This will take your tableview to the first row.
You can use ESCAPE
:
WHERE columnName LIKE '%\%%' ESCAPE '\'
try $conn = mysql_connect("localhost", "root")
or $conn = mysql_connect("localhost", "root", "")
First, you'll need to add session_start()
at the top of any page that you wish to use SESSION
variables on.
Also, you should check to make sure the variable is set first before using it:
if(isset($_SESSION['SESS_fname'])){
echo $_SESSION['SESS_fname'];
}
Or, simply:
echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");
Java SE is use for the desktop applications and simple core functions. Java EE is used for desktop, but also web development, networking, and advanced things.
Aside from limiting the columns selected to reduce bandwidth and memory:
DataTable t;
t.Columns.Remove("columnName");
t.Columns.RemoveAt(columnIndex);
That's because the browser doesn't transmit that part to the server, sorry.
Kotlin
do this instead:For Example,
// * The Method I Mentioned Above
private fun parseTheValue(@NonNull valueYouWantToParse: String)
{
val intent = Intent(this, AnotherActivity::class.java)
intent.putExtra("value", valueYouWantToParse)
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent)
this.finish()
}
Then just call parseTheValue("the String that you want to parse")
e.g,
val theValue: String
parseTheValue(theValue)
then in the other activity,
val value: Bundle = intent.extras!!
// * enter the `name` from the `@param`
val str: String = value.getString("value").toString()
// * For testing
println(str)
Hope This Help, Happy Coding!

I actually use a makefile to build any dependencies needed before invoking devenv to build a particular project as in the following:
debug: coratools_debug
devenv coralib.vcproj /build debug
coratools_debug: nothing
cd ../coratools
nmake debug
cd $(MAKEDIR)
You can also use the msbuild tool to do the same thing:
debug: coratools_debug
msbuild coralib.vcxproj /p:Configuration=debug
coratools_debug: nothing
cd ../coratools
nmake debug
cd $(MAKEDIR)
In my opinion, this is much easier than trying to figure out the overly complicated visual studio project management scheme.
Here's another version, and it's arguably a bit simpler.
multipetal <- function(df, n) {
varname <- paste("petal", n, sep=".")
df<-mutate_(df, .dots=setNames(paste0("Petal.Width*",n), varname))
df
}
for(i in 2:5) {
iris <- multipetal(df=iris, n=i)
}
> head(iris)

First select drive that is where Android sdk folder is there. Then you Follow the below steps
cd DriveName:/ or Ex : cd c:/ Press 'Enter'
then you will give the path that is adb console path is there in a platform-tools folder so cd Root Folder/inner root folder if there/Platform-tools Press 'Enter' then it selects the adb directory.
In my case I misspelled , I was referring as ngmodel istead of ngModel :) Hope It helps!

In order to achieve what you want, you would have to write two applications (in either Java or Python, for example):
Bridge app that sits on the client's machine and can deal with both TCP/IP sockets and WebSockets. It will interact with the TCP/IP socket in question.
Server-side app (such as a JSP/Servlet WAR) that can talk WebSockets. It includes at least one HTML page (including server-side processing code if need be) to be accessed by a browser.
It should work like this
Note 1: The above steps are a vast simplification and do not include information about error handling and keepAlive requests, in the event that either client disconnects prematurely or the server needs to inform clients that it is shutting down/restarting.
Note 2: Depending on your needs, it might be possible to merge these components into one if the TCP/IP socket server in question (to which the bridge talks) is on the same machine as the server app.
$(document).ready(function () {
$(".trigger").click(function () {
$("#sidebar").toggle("fast");
$("#sidebar").toggleClass("active");
return false;
});
});
<div>
<a class="trigger" href="#">
<img id="icon-menu" alt='menu' height='50' src="Images/Push Pin.png" width='50' />
</a>
</div>
<div id="sidebar">
</div>
Instead #sidebar give the id of ur div.
you can get dynamic object's key with by trying this
myObj['key']
Do Cmd+F12+Fn Key on mac in IntelliJ if clicking Cmd+F12 starts.
In order to trap repeated clicks on the same cell, you need to move the focus to a different cell, so that each time you click, you are in fact moving the selection.
The code below will select the top left cell visible on the screen, when you click on any cell. Obviously, it has the flaw that it won't trap a click on the top left cell, but that can be managed (eg by selecting the top right cell if the activecell is the top left).
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'put your code here to process the selection, then..
ActiveWindow.VisibleRange.Cells(1, 1).Select
End Sub
I also had same problem in past. All had happend after moving database files to new location and after updating mysql server. All tables with InnoDB engine disappeared from my database. I was trying to recreate them, but mysql told me 1146: Table 'xxx' doesn't exist
all the time until I had recreated my database and restarted mysql service.
I think there's a need to read about InnoDB table binaries.
If you don't care about row order (which I don't think you do), then you can use a Linux/FreeBSD/Mac OS X/Cygwin box and do:
$ cat yourfile | sort | uniq > yourfile_nodups
Then open the file again in Notepad++.
I believe, the usage of and the difference between Factory & Builder patterns can be understood/clarified easier in a certain time period as you worked on the same code base and changing requirements.
From my experience, usually, you start with a Factory pattern including couple of static creator methods to primarily hide away relatively complex initialisation logic. As your object hierarchy gets more complex (or as you add more types, parameters), you probably end up having your methods populated with more parameters and not to mention you gonna have to recompile your Factory module. All those stuff, increases the complexity of your creator methods, decreases the readability and makes the creation module more fragile.
This point possibly will be the transition/extension point. By doing so, you create a wrapper module around the construction parameters and then you will be able represent new (similar) objects by adding some more abstractions(perhaps) and implementations without touching actual your creation logic. So you've had "less" complex logic.
Frankly, referring to something sort of "having an object created in one-step or multiple steps is the difference" as the sole diversity factor was not sufficient for me to distinguish them since I could use both ways for almost all cases I faced up to now without experiencing any benefit. So this is what I've finally thought about it.
There is a really useful extension called "xdebug" that will make your reports much nicer as well.
I had the same problem and also use Linux Mint (as nuduoz) . I my case problem was solved after i added boost_system
to GCC C++ Linker->Libraries
.
The reject
actually takes one parameter: that's the exception that occurred in your code that caused the promise to be rejected. So, when you call reject()
the exception value is undefined
, hence the "undefined" part in the error that you get.
You do not show the code that uses the promise, but I reckon it is something like this:
var promise = doSth();
promise.then(function() { doSthHere(); });
Try adding an empty failure call, like this:
promise.then(function() { doSthHere(); }, function() {});
This will prevent the error to appear.
However, I would consider calling reject
only in case of an actual error, and also... having empty exception handlers isn't the best programming practice.
Exactly what you need:) You can choose callback version or Promise version. Note that promises will work in IE only with Promise polyfill lib.You can put this code once on a page, and this function will appear in all your files.
The loadend event is fired when progress has stopped on the loading of a resource (e.g. after "error", "abort", or "load" have been dispatched)
Callback version
File.prototype.convertToBase64 = function(callback){
var reader = new FileReader();
reader.onloadend = function (e) {
callback(e.target.result, e.target.error);
};
reader.readAsDataURL(this);
};
$("#asd").on('change',function(){
var selectedFile = this.files[0];
selectedFile.convertToBase64(function(base64){
alert(base64);
})
});
Promise version
File.prototype.convertToBase64 = function(){
return new Promise(function(resolve, reject) {
var reader = new FileReader();
reader.onloadend = function (e) {
resolve({
fileName: this.name,
result: e.target.result,
error: e.target.error
});
};
reader.readAsDataURL(this);
}.bind(this));
};
FileList.prototype.convertAllToBase64 = function(regexp){
// empty regexp if not set
regexp = regexp || /.*/;
//making array from FileList
var filesArray = Array.prototype.slice.call(this);
var base64PromisesArray = filesArray.
filter(function(file){
return (regexp).test(file.name)
}).map(function(file){
return file.convertToBase64();
});
return Promise.all(base64PromisesArray);
};
$("#asd").on('change',function(){
//for one file
var selectedFile = this.files[0];
selectedFile.convertToBase64().
then(function(obj){
alert(obj.result);
});
});
//for all files that have file extention png, jpeg, jpg, gif
this.files.convertAllToBase64(/\.(png|jpeg|jpg|gif)$/i).then(function(objArray){
objArray.forEach(function(obj, i){
console.log("result[" + obj.fileName + "][" + i + "] = " + obj.result);

IIS7 defines a defaultDocument section in its configuration files which can be found in the %WinDir%\System32\InetSrv\Config folder. Most likely, the file index.aspx is already defined as a default document in one of IIS7's configuration files and you are adding it again in your web.config.
I suspect that removing the line
<add value="index.aspx" />
from the defaultDocument/files section will fix your issue.
The defaultDocument section of your config will look like:
<defaultDocument>
<files>
<remove value="default.aspx" />
<remove value="index.html" />
<remove value="iisstart.htm" />
<remove value="index.htm" />
<remove value="Default.asp" />
<remove value="Default.htm" />
</files>
</defaultDocument>
Note that index.aspx will still appear in the list of default documents for your site in the IIS manager.
For more information about IIS7 configuration, click here.
Each time the same will be generated:
if let uuid = UIDevice.current.identifierForVendor?.uuidString {

Each time a new one will be generated:
let uuid = UUID().uuidString

Remove jars you added recently in the web-inf ->lib. for example jstl jars.
You could try the search feature in pip,
$ pip search yaml
which looks for packages in PyPI with yaml in the short description. That reveals various packages, including PyYaml, yamltools, and PySyck, among others (Note that PySyck docs recommend using PyYaml, since syck is out of date). Now you know a specific package name, you can install it:
$ pip install pyyaml
If you want to install python yaml system-wide in linux, you can also use a package manager, like aptitude
or yum
:
$ sudo apt-get install python-yaml
$ sudo yum install python-yaml
Go to terminal
$ adb -s UDID shell
$ ip addr | grep inet
or
$ netcfg | grep inet
I would like to give another example where groupby without sort is not working. Adapted from example by James Sulak
from itertools import groupby
things = [("vehicle", "bear"), ("animal", "duck"), ("animal", "cactus"), ("vehicle", "speed boat"), ("vehicle", "school bus")]
for key, group in groupby(things, lambda x: x[0]):
for thing in group:
print "A %s is a %s." % (thing[1], key)
print " "
output is
A bear is a vehicle.
A duck is a animal.
A cactus is a animal.
A speed boat is a vehicle.
A school bus is a vehicle.
there are two groups with vehicule, whereas one could expect only one group
I have used the technique said above, still I found that the time given in the Code:Blocks IDE was more or less similar to the result obtained-(may be it will differ by little micro seconds)..
something.data()
will return a pointer to the data space of the vector.
double quotes worked in oracle when I had the keyword as one of the column name.
eg:
select t."size" from table t
answer = True
myvar = "the answer is " + str(answer)
or
myvar = "the answer is %s" % answer
Another way to understand it is to figure out what error code it eliminates by having attr_accessor
.
Example:
class BankAccount
def initialize( account_owner )
@owner = account_owner
@balance = 0
end
def deposit( amount )
@balance = @balance + amount
end
def withdraw( amount )
@balance = @balance - amount
end
end
The following methods are available:
$ bankie = BankAccout.new("Iggy")
$ bankie
$ bankie.deposit(100)
$ bankie.withdraw(5)
The following methods throws error:
$ bankie.owner #undefined method `owner'...
$ bankie.balance #undefined method `balance'...
owner
and balance
are not, technically, a method, but an attribute. BankAccount class does not have def owner
and def balance
. If it does, then you can use the two commands below. But those two methods aren't there. However, you can access attributes as if you'd access a method via attr_accessor
!! Hence the word attr_accessor
. Attribute. Accessor. It accesses attributes like you would access a method.
Adding attr_accessor :balance, :owner
allows you to read and write balance
and owner
"method". Now you can use the last 2 methods.
$ bankie.balance
$ bankie.owner
Your problem is that the indices returned by match.start()
correspond to the position of the character as it appeared in the original string when you matched it; however, as you rewrite the string c
every time, these indices become incorrect.
The best approach to solve this is to use replaceAll
, for example:
System.out.println(c.replaceAll("[^a-zA-Z0-9]", ""));
