in java when you set a value to variable, it return new value. So
private boolean getValue()
{
return value = !value;
}
This is what I did:
Suppose you have the following code, in this code, we have a Passenger class with a couple of properties that we want to sort based on.
public class Passenger
{
public string Name { get; }
public string LastName { get; }
public string PassportNo { get; }
public string Nationality { get; }
public Passenger(string name, string lastName, string passportNo, string nationality)
{
this.Name = name;
this.LastName = lastName;
this.PassportNo = passportNo;
this.Nationality = nationality;
}
public static int CompareByName(Passenger passenger1, Passenger passenger2)
{
return String.Compare(passenger1.Name, passenger2.Name);
}
public static int CompareByLastName(Passenger passenger1, Passenger passenger2)
{
return String.Compare(passenger1.LastName, passenger2.LastName);
}
public static int CompareNationality(Passenger passenger1, Passenger passenger2)
{
return String.Compare(passenger1.Nationality, passenger2.Nationality);
}
}
public class TestPassengerSort
{
Passenger p1 = new Passenger("Johon", "Floid", "A123456789", "USA");
Passenger p2 = new Passenger("Jo", "Sina", "A987463215", "UAE");
Passenger p3 = new Passenger("Ped", "Zoola", "A987855215", "Italy");
public void SortThem()
{
Passenger[] passengers = new Passenger[] { p1, p2, p3 };
List<Passenger> passengerList = new List<Passenger> { p1, p2, p3 };
Array.Sort(passengers, Passenger.CompareByName);
Array.Sort(passengers, Passenger.CompareByLastName);
Array.Sort(passengers, Passenger.CompareNationality);
passengerList.Sort(Passenger.CompareByName);
passengerList.Sort(Passenger.CompareByLastName);
passengerList.Sort(Passenger.CompareNationality);
}
}
So you can implement your sort structure by using Composition delegate.
Packaging of pom
is used in projects that aggregate other projects, and in projects whose only useful output is an attached artifact from some plugin. In your case, I'd guess that your top-level pom includes <modules>...</modules>
to aggregate other directories, and the actual output is the result of one of the other (probably sub-) directories. It will, if coded sensibly for this purpose, have a packaging of war
.
The steps mentioned by Jason are very good and should work. There is a little twist with SQL Developer, though. It caches the connection specifications (host, service name, port) the first time it reads the tnsnames.ora file. Then, it does not invalidate the specs when the original entry is removed from the tnsname.ora file. The cache persists even after SQL Developer has been terminated and restarted. This is not such an illogical way of handling the situation. Even if a tnsnames.ora file is temporarily unavailable, SQL Developer can still make the connection as long as the original specifications are still true. The problem comes with their next little twist. SQL Developer treats service names in the tnsnames.ora file as case-sensitive values when resolving the connection. So if you used to have an entry name ABCD.world in the file and you replaced it with an new entry named abcd.world, SQL Developer would NOT update its connection specs for ABCD.world - it will treat abcd.world as a different connection altogether. Why am I not surprised that an Oracle product would treat as case-sensitive the contents of an oracle-developed file format that is expressly case-insensitive?
The lock screen works without keyguard i have tested it. The home button stops working and you can't get to task manager by holding the home key. I wish they didn't develop a new process when it used to be built into system ui or whatever. I don't see the need for the change and extra process

Just found sys.executable
- the full path to the current Python executable, which can be used to run the script (instead of relying on the shbang, which obviously doesn't work on Windows)

Lombok
supports var but it's still classified as experimental:
import lombok.experimental.var;
var number = 1; // Inferred type: int
number = 2; // Legal reassign since var is not final
number = "Hi"; // Compilation error since a string cannot be assigned to an int variable
System.out.println(number);
Here is a pitfall to avoid when trying to use it in IntelliJ IDEA
. It appears to work as expected though including auto completion and everything. Until there is a "non-hacky" solution (e.g. due to JEP 286: Local-Variable Type Inference), this might be your best bet right now.
Note that val
is support by Lombok
as well without modifying or creating a lombok.config
.
As said by Scott Chamberlain(and several others), Tuples work best if you don't mind having immutable(ie read-only) objects.
If, like suggested by David, you want to reference the int by the string value, for example, you should use a dictionary
Dictionary<string, int> d = new Dictionary<string, int>();
d.Add("string", 1);
Console.WriteLine(d["string"]);//prints 1
If, however, you want to store your elements mutably in a list, and don't want to use a dictionary-style referencing system, then your best bet(ie only real solution right now) would be to use KeyValuePair, which is essentially std::pair for C#:
var kvp=new KeyValuePair<int, string>(2, "a");
//kvp.Key=2 and a.Value="a";
kvp.Key = 3;//both key and
kvp.Value = "b";//value are mutable
Of course, this is stackable, so if you need a larger tuple(like if you needed 4 elements) you just stack it. Granted this gets ugly really fast:
var quad=new KeyValuePair<KeyValuePair<int,string>, KeyValuePair<int,string>>
(new KeyValuePair<int,string>(3,"a"),
new KeyValuePair<int,string>(4,"b"));
//quad.Key.Key=3
So obviously if you were to do this, you should probably also define an auxiliary function.
My advice is that if your tuple contains more than 2 elements, define your own class. You could use a typedef-esque using statement like :
using quad = KeyValuePair<KeyValuePair<int,string>, KeyValuePair<int,string>>;
but that doesn't make your instantiations any easier. You'd probably spend a lot less time writing template parameters and more time on the non-boilerplate code if you go with a user-defined class when working with tuples of more than 2 elements
Property hibernate.allow_refresh_detached_entity
did the trick for me. But it is a general rule, so it is not very suitable if you want to do it only in some cases. I hope it helps.
Tested on Hibernate 5.4.9
Enable general query log by the following query in mysql command line
SET GLOBAL general_log = 'ON';
Now open C:/xampp/mysql/data/mysql.log
and check query log
If it fails, open your my.cnf
file. For windows its my.ini
file and enable it there. Just make sure its in the [mysqld]
section
[mysqld]
general_log = 1
Note: In xampp my.ini
file can be either found in xampp\mysql
or in c:\windows
directory
If your iPhone is jailbroken you can use DemoGod
On Python 3 numpy.genfromtxt
expects a bytes stream. Use the following:
numpy.genfromtxt(io.BytesIO(x.encode()))
You are trying to execute the number in the ENDTIME
as a command. You should also see an error like 1370306857: command not found
. Instead use the arithmetic expansion:
echo "It takes $(($ENDTIME - $STARTTIME)) seconds to complete this task..."
You could also save the commands in a separate script, commands.sh
, and use time command:
time commands.sh
Try this:
$str = htmlentities($str,ENT_QUOTES,'UTF-8');
So, after filtering your data using htmlentities()
function, you can use the data in XML tag like:
<mytag>$str</mytag>
Just use Collections.sort(yourListHere)
here to sort.
You can read more about Collections from here.
One is a function that prints to stdout. The other is an object that provides several member functions and overloads of operator<<
that print to stdout. There are many more differences that I could enumerate, but I'm not sure what you are after.
This cannot be done for the table; besides, you even cannot change this default value at all.
The answer is a server variable datetime_format, it is unused.
JSON string that needs to be deserialized will have to contain the type information about parameter T
.
You will have to put Jackson annotations on every class that can be passed as parameter T
to class Data
so that the type information about parameter type T
can be read from / written to JSON string by Jackson.
Let us assume that T
can be any class that extends abstract class Result
.
class Data <T extends Result> {
int found;
Class<T> hits
}
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT)
@JsonSubTypes({
@JsonSubTypes.Type(value = ImageResult.class, name = "ImageResult"),
@JsonSubTypes.Type(value = NewsResult.class, name = "NewsResult")})
public abstract class Result {
}
public class ImageResult extends Result {
}
public class NewsResult extends Result {
}
Once each of the class (or their common supertype) that can be passed as parameter T
is annotated, Jackson will include information about parameter T
in the JSON. Such JSON can then be deserialized without knowing the parameter T
at compile time.
This Jackson documentation link talks about Polymorphic Deserialization but is useful to refer to for this question as well.
javadocs show that the parse method is overloaded.
Create a StringStream or InputSource using your string XML and you should be set.
The trick here is defining "reverse". One can modify the list in place, create a copy in reverse order, or create a view in reversed order.
The simplest way, intuitively speaking, is Collections.reverse
:
Collections.reverse(myList);
This method modifies the list in place. That is, Collections.reverse
takes the list and overwrites its elements, leaving no unreversed copy behind. This is suitable for some use cases, but not for others; furthermore, it assumes the list is modifiable. If this is acceptable, we're good.
If not, one could create a copy in reverse order:
static <T> List<T> reverse(final List<T> list) {
final List<T> result = new ArrayList<>(list);
Collections.reverse(result);
return result;
}
This approach works, but requires iterating over the list twice. The copy constructor (new ArrayList<>(list)
) iterates over the list, and so does Collections.reverse
. We can rewrite this method to iterate only once, if we're so inclined:
static <T> List<T> reverse(final List<T> list) {
final int size = list.size();
final int last = size - 1;
// create a new list, with exactly enough initial capacity to hold the (reversed) list
final List<T> result = new ArrayList<>(size);
// iterate through the list in reverse order and append to the result
for (int i = last; i >= 0; --i) {
final T element = list.get(i);
result.add(element);
}
// result now holds a reversed copy of the original list
return result;
}
This is more efficient, but also more verbose.
Alternatively, we can rewrite the above to use Java 8's stream
API, which some people find more concise and legible than the above:
static <T> List<T> reverse(final List<T> list) {
final int last = list.size() - 1;
return IntStream.rangeClosed(0, last) // a stream of all valid indexes into the list
.map(i -> (last - i)) // reverse order
.mapToObj(list::get) // map each index to a list element
.collect(Collectors.toList()); // wrap them up in a list
}
nb. that Collectors.toList()
makes very few guarantees about the result list. If you want to ensure the result comes back as an ArrayList, use Collectors.toCollection(ArrayList::new)
instead.
The third option is to create a view in reversed order. This is a more complicated solution, and worthy of further reading/its own question. Guava's Lists#reverse method is a viable starting point.
Choosing a "simplest" implementation is left as an exercise for the reader.
From the answer here, spark.sql.shuffle.partitions
configures the number of partitions that are used when shuffling data for joins or aggregations.
spark.default.parallelism
is the default number of partitions in RDD
s returned by transformations like join
, reduceByKey
, and parallelize
when not set explicitly by the user. Note that spark.default.parallelism
seems to only be working for raw RDD
and is ignored when working with dataframes.
If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions)
(don't forget to assign it to a new val
) in your code.
To change the settings in your code you can simply do:
sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")
Alternatively, you can make the change when submitting the job to a cluster with spark-submit
:
./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300
In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, @
:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new { @class = "myclass"})
For VB.NET this syntax would be accomplished using the dot, .
, which in that language is default syntax for all anonymous types:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })
The html code you written is absolutely perfect
<ul class="nav navbar-nav list-inline">
<li class="list-inline-item">FB</li>
<li class="list-inline-item">G+</li>
<li class="list-inline-item">T</li>
</ul>
The reasons that could be possible is
1. Check out the CSS for class name "nav" or "navbar-nav" may be over writing it, try to remove and debug the class names in the ul element.
2. Check any of the child element(a tag or "social-icon" class) is using block level CSS style
3. Check out your using a HTML5 !DOCTYPE html
4. Place your bootstrap.css link at the last before closing your head tag
5. Change text-xs-center to text-center because xs is dropped in Bootstrap 4.
This One will work perfectly fine
<!-- Use this inside Head tag-->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/js/bootstrap.min.js"></script>
<!-- Use this inside Body tag-->
<div class="container">
<ul class="list-inline">
<li class="list-inline-item"><a class="social-icon text-center" target="_blank" href="#">FB</a></li>

<li class="list-inline-item"><a class="social-icon text-center" target="_blank" href="#">T</a></li>
</ul>

function changeStyle(findSelector, newRules) {
// Change original css style declaration.
for ( s in document.styleSheets ) {

for ( x in CssRulesStyle ) {
if ( CssRulesStyle[x].selectorText == findSelector) {
for ( cssprop in newRules ) {

It's getElementsByName()
and getElementsByTagName()
- note the "s" in "Elements", indicating that both functions return a list of elements, i.e., a NodeList, which you will access like an array. Note that the second function ends with "TagName" not "Tag".
Even if the function only returns one element it will still be in a NodeList of length one. So:
var els = document.getElementsByName('frmMain');
// els.length will be the number of elements returned
// els[0] will be the first element returned
// els[1] the second, etc.
Assuming your form is the first (or only) form on the page you can do this:
document.getElementsByName('frmMain')[0].elements
document.getElementsByTagName('table')[0].elements
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
int rowIndex = e.RowIndex; // Get the order of the current row
DataGridViewRow row = dataGridView1.Rows[rowIndex];//Store the value of the current row in a variable
MessageBox.Show(row.Cells[rowIndex].Value.ToString());//show message for current row
}
I have gone through all the answers and i come up with my own answer which first check whether Internet is available and if Internet is available then it check whether it is active or not.
I have included all necessary method and classes to check for active Internet connection.
NetworkUtils.class
public class NetworkUtils {
public static final int STATUS_CONNECTED = 0 ;
public static boolean isInternetAvailable(Context ctx){
ConnectivityManager cm = (ConnectivityManager)ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
return activeNetwork != null && activeNetwork.isConnectedOrConnecting();
}
public static int isInternetActiveWithPing() {
try {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
int exitValue = process.waitFor();
return exitValue;
} catch (Exception ex) {
return -1;
}
}
public static boolean isInternetActiveWithInetAddress() {
try {
InetAddress inetAddress = InetAddress.getByName("www.google.com");
return inetAddress != null && !inetAddress.toString().equals("");
} catch (Exception ex) {
return false;
}
}
public static void displayInternetConnectionMessage(Context ctx){
Toast.makeText(ctx, "Check Internet Connection", Toast.LENGTH_SHORT).show();
}
}
You can check whether Internet is active using below code:
private void checkInternetConnection() {
if (NetworkUtils.isInternetAvailable(this)) {
new Thread(new Runnable() {
@Override
public void run() {
if (NetworkUtils.isInternetActiveWithPing() == NetworkUtils.STATUS_CONNECTED) {
performNetworkingOperations();
} else {
if (NetworkUtils.isInternetActiveWithInetAddress()) {
performNetworkingOperations();
} else {
displayConnectionMessage();
}
}
}
}).start();
} else {
displayConnectionMessage();
}
}
private void performNetworkingOperations() {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, "Internet is Available", Toast.LENGTH_SHORT).show();
}
});
}
private void displayConnectionMessage() {
runOnUiThread(new Runnable() {
@Override
public void run() {
NetworkUtils.displayInternetConnectionMessage(MainActivity.this);
}
});
}
Or, if you are doing a split - join:
GROUP_CONCAT(split(thing, " "), '----') AS thing_name,
You may want to inclue WITHIN RECORD
, like this:
GROUP_CONCAT(split(thing, " "), '----') WITHIN RECORD AS thing_name,
from BigQuery API page
function getOnemonthBefore($date){
$day = intval(date("t", strtotime("$date")));//get the last day of the month
$month_date = date("y-m-d",strtotime("$date -$day days"));//get the day 1 month before
return $month_date;
}
The resulting date is dependent to the number of days the input month is consist of. If input month is february (28 days), 28 days before february 5 is january 8. If input is may 17, 31 days before is april 16. Likewise, if input is may 31, resulting date will be april 30.
NOTE: the input takes complete date ('y-m-d') and outputs ('y-m-d') you can modify this code to suit your needs.
I know this is a pretty old topic, but I also had a same problem.
My solution:
how we fill the combobox:
foreach (KeyValuePair<int, string> item in listRegion)
{
combo.Items.Add(item.Value);
combo.ValueMember = item.Value.ToString();
combo.DisplayMember = item.Key.ToString();
combo.SelectedIndex = 0;
}
and that's how we get inside:
MessageBox.Show(combo_region.DisplayMember.ToString());
I hope it help someone
An optional way if you want to use pure Python:
ElementTree is good for most cases, but it can't CData and pretty print.
So, if you need CData and pretty print you should use minidom:
minidom_example.py:
from xml.dom import minidom
doc = minidom.Document()
root = doc.createElement('root')
doc.appendChild(root)
leaf = doc.createElement('leaf')
text = doc.createTextNode('Text element with attributes')
leaf.appendChild(text)
leaf.setAttribute('color', 'white')
root.appendChild(leaf)
leaf_cdata = doc.createElement('leaf_cdata')
cdata = doc.createCDATASection('<em>CData</em> can contain <strong>HTML tags</strong> without encoding')
leaf_cdata.appendChild(cdata)
root.appendChild(leaf_cdata)
branch = doc.createElement('branch')
branch.appendChild(leaf.cloneNode(True))
root.appendChild(branch)
mixed = doc.createElement('mixed')
mixed_leaf = leaf.cloneNode(True)
mixed_leaf.setAttribute('color', 'black')
mixed_leaf.setAttribute('state', 'modified')
mixed.appendChild(mixed_leaf)
mixed_text = doc.createTextNode('Do not use mixed elements if it possible.')
mixed.appendChild(mixed_text)
root.appendChild(mixed)
xml_str = doc.toprettyxml(indent=" ")
with open("minidom_example.xml", "w") as f:
f.write(xml_str)
minidom_example.xml:
<?xml version="1.0" ?>
<root>
<leaf color="white">Text element with attributes</leaf>
<leaf_cdata>
<![CDATA[<em>CData</em> can contain <strong>HTML tags</strong> without encoding]]> </leaf_cdata>
<branch>
<leaf color="white">Text element with attributes</leaf>
</branch>
<mixed>
<leaf color="black" state="modified">Text element with attributes</leaf>
Do not use mixed elements if it possible.
</mixed>
</root>
If array is static allocated:
size_t size = sizeof(arr) / sizeof(int);
if array is dynamic allocated(heap):
int *arr = malloc(sizeof(int) * size);
where variable size is a dimension of the arr.
In my case (new sql server install, newly created user) my user simply didn't have the necessary permission. I logged to the Management Studio as sa, then went to Security/Logins, right-click my username, Properties, then in the Server Roles section I checked sysadmin
.
max(ozone$Ozone, na.rm = TRUE)
should do the trick. Remember to include the na.rm = TRUE
or else R will return NA.
CPU Virtualization is enabled by default on all MacBooks with compatible CPUs (i7 is compatible). You can try to reset PRAM if you think it was disabled somehow, but I doubt it.
I think the issue might be in the old version of OS. If your MacBook is i7, then you better upgrade OS to something newer.
Arguments are passed by assignment. The rationale behind this is twofold:
So:
If you pass a mutable object into a method, the method gets a reference to that same object and you can mutate it to your heart's delight, but if you rebind the reference in the method, the outer scope will know nothing about it, and after you're done, the outer reference will still point at the original object.
If you pass an immutable object to a method, you still can't rebind the outer reference, and you can't even mutate the object.
To make it even more clear, let's have some examples.
Let's try to modify the list that was passed to a method:
def try_to_change_list_contents(the_list):
print('got', the_list)
the_list.append('four')
print('changed to', the_list)
outer_list = ['one', 'two', 'three']
print('before, outer_list =', outer_list)
try_to_change_list_contents(outer_list)
print('after, outer_list =', outer_list)
Output:
before, outer_list = ['one', 'two', 'three']
got ['one', 'two', 'three']
changed to ['one', 'two', 'three', 'four']
after, outer_list = ['one', 'two', 'three', 'four']
Since the parameter passed in is a reference to outer_list
, not a copy of it, we can use the mutating list methods to change it and have the changes reflected in the outer scope.
Now let's see what happens when we try to change the reference that was passed in as a parameter:
def try_to_change_list_reference(the_list):
print('got', the_list)
the_list = ['and', 'we', 'can', 'not', 'lie']
print('set to', the_list)
outer_list = ['we', 'like', 'proper', 'English']
print('before, outer_list =', outer_list)
try_to_change_list_reference(outer_list)
print('after, outer_list =', outer_list)
Output:
before, outer_list = ['we', 'like', 'proper', 'English']
got ['we', 'like', 'proper', 'English']
set to ['and', 'we', 'can', 'not', 'lie']
after, outer_list = ['we', 'like', 'proper', 'English']
Since the the_list
parameter was passed by value, assigning a new list to it had no effect that the code outside the method could see. The the_list
was a copy of the outer_list
reference, and we had the_list
point to a new list, but there was no way to change where outer_list
pointed.
It's immutable, so there's nothing we can do to change the contents of the string
Now, let's try to change the reference
def try_to_change_string_reference(the_string):
print('got', the_string)
the_string = 'In a kingdom by the sea'
print('set to', the_string)
outer_string = 'It was many and many a year ago'
print('before, outer_string =', outer_string)
try_to_change_string_reference(outer_string)
print('after, outer_string =', outer_string)
Output:
before, outer_string = It was many and many a year ago
got It was many and many a year ago
set to In a kingdom by the sea
after, outer_string = It was many and many a year ago
Again, since the the_string
parameter was passed by value, assigning a new string to it had no effect that the code outside the method could see. The the_string
was a copy of the outer_string
reference, and we had the_string
point to a new string, but there was no way to change where outer_string
pointed.
I hope this clears things up a little.
EDIT: It's been noted that this doesn't answer the question that @David originally asked, "Is there something I can do to pass the variable by actual reference?". Let's work on that.
As @Andrea's answer shows, you could return the new value. This doesn't change the way things are passed in, but does let you get the information you want back out:
def return_a_whole_new_string(the_string):
new_string = something_to_do_with_the_old_string(the_string)
return new_string
# then you could call it like
my_string = return_a_whole_new_string(my_string)
If you really wanted to avoid using a return value, you could create a class to hold your value and pass it into the function or use an existing class, like a list:
def use_a_wrapper_to_simulate_pass_by_reference(stuff_to_change):
new_string = something_to_do_with_the_old_string(stuff_to_change[0])
stuff_to_change[0] = new_string
# then you could call it like
wrapper = [my_string]
use_a_wrapper_to_simulate_pass_by_reference(wrapper)
do_something_with(wrapper[0])
Although this seems a little cumbersome.
Have a look at iconv()
or mb_convert_encoding()
.
Just by the way: why don't utf8_encode()
and utf8_decode()
work for you?
utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1
utf8_encode — Encodes an ISO-8859-1 string to UTF-8
So essentially
$utf8 = 'ÄÖÜ'; // file must be UTF-8 encoded
$iso88591_1 = utf8_decode($utf8);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);
$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');
$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 encoded
$utf8_1 = utf8_encode($iso88591);
$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);
$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');
all should do the same - with utf8_en/decode()
requiring no special extension, mb_convert_encoding()

I know this is a little old question, but things changed. Laravel isn't that slow. It's, as mentioned, synced folders are slow. However, on Windows 10 I wasn't able to use rsync
. I tried both cygwin
and minGW
. It seems like rsync
is incompatible with git for windows
's version of ssh
.
Here is what worked for me: NFS.
Vagrant docs says:
NFS folders do not work on Windows hosts. Vagrant will ignore your request for NFS synced folders on Windows.
This isn't true anymore. We can use vagrant-winnfsd
plugin nowadays. It's really simple to install:
vagrant plugin install vagrant-winnfsd
Vagrantfile
: config.vm.synced_folder ".", "/vagrant", type: "nfs"
Vagrantfile
: config.vm.network "private_network", type: "dhcp"
That's all I needed to make NFS
work. Laravel response time decreased from 500ms to 100ms for me.
From the term "automatic login" I suppose security (password protection) is not of key importance here.
The guidelines for solution could be to use a JavaScript bookmark (idea borrowed form a nice game published on M&M's DK site).
The idea is to create a javascript file and store it locally. It should do the login data entering depending on current site address. Just an example using jQuery:
// dont forget to include jQuery code
// preferably with .noConflict() in order not to break the site scripts
if (window.location.indexOf("mail.google.com") > -1) {
// Lets login to Gmail
jQuery("#Email").val("[email protected]");
jQuery("#Passwd").val("superSecretPassowrd");
jQuery("#gaia_loginform").submit();
}
Now save this as say login.js
Then create a bookmark (in any browser) with this (as an) url:
javascript:document.write("<script type='text/javascript' src='file:///path/to/login.js'></script>");
Now when you go to Gmail and click this bookmark you will get automatically logged in by your script.
Multiply the code blocks in your script, to add more sites in the similar manner. You could even combine it with window.open(...)
functionality to open more sites, but that may get the script inclusion more complicated.
Note: This only illustrates an idea and needs lots of further work, it's not a complete solution.
I think it's not simple to set caret to some position in contenteditable element. I wrote my own code for this. It bypasses the node tree calcing how many characters left and sets caret in needed element. I didn't test this code much.
//Set offset in current contenteditable field (for start by default or for with forEnd=true)
function setCurSelectionOffset(offset, forEnd = false) {
const sel = window.getSelection();
if (sel.rangeCount !== 1 || !document.activeElement) return;
const firstRange = sel.getRangeAt(0);
if (offset > 0) {
bypassChildNodes(document.activeElement, offset);
}else{
if (forEnd)
firstRange.setEnd(document.activeElement, 0);
else
firstRange.setStart(document.activeElement, 0);
}
//Bypass in depth
function bypassChildNodes(el, leftOffset) {
const childNodes = el.childNodes;
for (let i = 0; i < childNodes.length && leftOffset; i++) {
const childNode = childNodes[i];
if (childNode.nodeType === 3) {
const curLen = childNode.textContent.length;
if (curLen >= leftOffset) {
if (forEnd)
firstRange.setEnd(childNode, leftOffset);
else
firstRange.setStart(childNode, leftOffset);
return 0;
}else{
leftOffset -= curLen;
}
}else
if (childNode.nodeType === 1) {
leftOffset = bypassChildNodes(childNode, leftOffset);
}
}
return leftOffset;
}
}
I also wrote code to get current caret position (didn't test):
//Get offset in current contenteditable field (start offset by default or end offset with calcEnd=true)
function getCurSelectionOffset(calcEnd = false) {
const sel = window.getSelection();
if (sel.rangeCount !== 1 || !document.activeElement) return 0;
const firstRange = sel.getRangeAt(0),
startContainer = calcEnd ? firstRange.endContainer : firstRange.startContainer,
startOffset = calcEnd ? firstRange.endOffset : firstRange.startOffset;
let needStop = false;
return bypassChildNodes(document.activeElement);
//Bypass in depth
function bypassChildNodes(el) {
const childNodes = el.childNodes;
let ans = 0;
if (el === startContainer) {
if (startContainer.nodeType === 3) {
ans = startOffset;
}else
if (startContainer.nodeType === 1) {
for (let i = 0; i < startOffset; i++) {
const childNode = childNodes[i];
ans += childNode.nodeType === 3 ? childNode.textContent.length :
childNode.nodeType === 1 ? childNode.innerText.length :
0;
}
}
needStop = true;
}else{
for (let i = 0; i < childNodes.length && !needStop; i++) {
const childNode = childNodes[i];
ans += bypassChildNodes(childNode);
}
}
return ans;
}
}
You also need to be aware of range.startOffset and range.endOffset contain character offset for text nodes (nodeType === 3) and child node offset for element nodes (nodeType === 1). range.startContainer and range.endContainer may refer to any element node of any level in the tree (of course they also can refer to text nodes).
While several of the solutions here will work, none handle overlap well and end up moving one item to below the other. If you are trying to layout data that will be dynamically bound you won't know until runtime that it looks bad.
What I like to do is simply create a single row table and apply the right float on the second cell. No need to apply a left-align on the first, that happens by default. This handles overlap perfectly by word-wrapping.
HTML
<table style="width: 100%;">
<tr><td>Left aligned stuff</td>
<td class="alignRight">Right aligned stuff</td></tr>
</table>
CSS
.alignRight {
float: right;
}
By useing this code below :
.classname{
background-image: url(images/paper.jpg);
background-position: center;
background-size: cover;
background-repeat: no-repeat;
}
Hope it works. Thanks

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment. (If the ‘-e’ flag is specified, then values from the environment override assignments in the makefile.

In general, utf8_general_ci is faster than utf8_unicode_ci, but less correct.
Here is the difference:
For any Unicode character set, operations performed using the _general_ci collation are faster than those for the _unicode_ci collation. For example, comparisons for the utf8_general_ci collation are faster, but slightly less correct, than comparisons for utf8_unicode_ci. The reason for this is that utf8_unicode_ci supports mappings such as expansions; that is, when one character compares as equal to combinations of other characters. For example, in German and some other languages “ß” is equal to “ss”. utf8_unicode_ci also supports contractions and ignorable characters. utf8_general_ci is a legacy collation that does not support expansions, contractions, or ignorable characters. It can make only one-to-one comparisons between characters.
Quoted from: http://dev.mysql.com/doc/refman/5.0/en/charset-unicode-sets.html
For more detailed explanation, please read the following post from MySQL forums: http://forums.mysql.com/read.php?103,187048,188748
As for utf8_bin: Both utf8_general_ci and utf8_unicode_ci perform case-insensitive comparison. In constrast, utf8_bin is case-sensitive (among other differences), because it compares the binary values of the characters.
It's very easy, using jersey-client, just include this maven dependency:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.25.1</version>
</dependency>
Then invoke it using this example:
String json = ClientBuilder.newClient().target("http://api.coindesk.com/v1/bpi/currentprice.json").request().accept(MediaType.APPLICATION_JSON).get(String.class);
Then use Google's Gson to parse the JSON:
Gson gson = new Gson();
Type gm = new TypeToken<CoinDeskMessage>() {}.getType();
CoinDeskMessage cdm = gson.fromJson(json, gm);
I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker
Base = declarative_base()
class MyTable(Base):
__tablename__ = 'MyTable'
id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
some_col = Column(String(500))
def __init__(self, some_col):
self.some_col = some_col
engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()
for class_instance in session.query(MyTable).all():
print(vars(class_instance))
session.close()
Just to add as no-one has posted an answer that includes how to actually iterate though a dataset inside a loop, you can use the keywords OFFSET FETCH.
Usage
DECLARE @i INT = 0;
SELECT @count= Count(*) FROM {TABLE}
WHILE @i <= @count
BEGIN
SELECT * FROM {TABLE}
ORDER BY {COLUMN}
OFFSET @i ROWS
FETCH NEXT 1 ROWS ONLY
SET @i = @i + 1;
END
if(($("#checkboxid1").is(":checked")) || ($("#checkboxid2").is(":checked"))
|| ($("#checkboxid3").is(":checked"))) {
//Your Code here
}
You can use this code to verify that checkbox is checked at least one.
Thanks!!

I have a local install of tensorflow 1.15.0 (with tensorboard obviously included) on MacOS.
For me, the path to the relevant file within my user directory is Library/Python/3.7/lib/python/site-packages/tensorboard/main.py. So, which
does not work for me, but you have to look for the file named main.py, which is weird since it apparently is named something else for other users.
UPDATE 2018 MAY:
Alternatively, you can embed Edge browser, but only targetting windows 10.
if addition please, if you have a long text please you can use this css code bellow;
text-overflow: ellipsis;
overflow: visible;
white-space: nowrap;
make the whole line text visible.
For those who still struggle with this problem in Xcode8. For me was a duplicate Certificate problem, this is how I solved it:
I read the answer of Nick and then I began my investigation. I checked all the keys and Certificates in my particular case (inside ~/Library/Keychains/System.keychain).
When I opened the file, I found that I had two iPhone Distribution Certificates (that was the certificate that Xcode was requesting me), one with the iOS Distribution private key that I have been using since the beginning, and another iPhone Distribution Certificate which its private Key had a name (iOS Distribution:NAME) that wasn´t familiar for me. I deleted this last certificate, started Xcode again and the problem was gone. xCode wasn´t able to resolve that conflict and that´s why it was giving signing certificate error all the time.
Check your keychains, maybe you have a duplicate certificate.
Seems to me that the right formula should be:
n64 = 4 * (n / 3) + (n % 3 != 0 ? 4 : 0)
JOptionPane.showMessageDialog(btn1, "you are clicked save button","title of dialog",2);
btn1 is a JButton variable and its used in this dialog to dialog open position btn1 or textfield etc, by default use null position of the frame.next your message and next is the title of dialog. 2 numbers of alert type icon 3 is the information 1,2,3,4. Ok I hope you understand it
They are normal symbols as 'a' or '?' or any other. Just (invisible) entries in a string. \r moves cursor to the beginning of the line. \n goes one line down.
As for your replacement, you haven't specified what language you're using, so here's the sketch:
someString.replace("\r\n", "\n").replace("\r", "\n")
If you need formatting the xml string to xml, try this:
String xmlStr = "your-xml-string";
Source xmlInput = new StreamSource(new StringReader(xmlStr));
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
transformer.transform(xmlInput,
new StreamResult(new FileOutputStream("response.xml")));
If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json
Json(someDictionaryObj, JsonRequestBehavior.AllowGet);
Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5
as for your web request...it seems ok at first glance..
I would use something like this..
public void WebRequestinJson(string url, string postData)
{
StreamWriter requestWriter;
var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;
webRequest.ContentType = "application/json";
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
}
}
May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.
I know it's an old Question, but i think some one can benefit from my solution.
select
SUBSTRING(column_name,1,CHARINDEX(' ',column_name,1)-1)
,SUBSTRING(SUBSTRING(column_name,CHARINDEX(' ',column_name,1)+1,LEN(column_name))

,LEN(column_name))
from table_name
Advantages:
Limitations:
Note: the solution can give sub-string up to to N.
To overcame the limitation we can use the following ref.
But again the above solution can't be use in a table (Actaully i wasn't able to use it).
Again i hope this solution can help some-one.
Update: In case of Records > 50000 it is not advisable to use LOOPS
as it will degrade the Performance
Most easy way..

Assuming maven project:

hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true
ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.
Let's say you have package name a.b.c.service.impl
. MyServiceImpl is in this package and so is ServiceMarker.
public interface ServiceMarker {
}
Same for repository marker. Let's say you have a.b.c.repository.impl
or a.b.c.dao.impl
package name. Then MyDaoImpl is in this this package and also Repositorymarker
public interface RepositoryMarker {
}
//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)

Have you tried with the custom format "#,##0.##"

Programmatically stepping and tracing through python code is possible too (and its easy!). Look at the sys.settrace() documentation for more details. Also here is a tutorial to get you started.

Please note that the problem is not white
color. It is because it is being transparent.
When an element is made transparent, all of its child element's opacity; alpha filter in IE 6 7 etc, is changed to the new value.
So you cannot say that it is white!
You can place an element above it, and change that element's transparency to 1
while changing the image's transparency to .2
or what so ever you want to.
If you prefer console snippet, raser, than filename, you can do this:
window.open(URL.createObjectURL(
new Blob([JSON.stringify(JSON)], {
type: 'application/binary'}

I suppese you alredy managed to solve it, but if someone is looking for similar solution then this worked for me:
g.append('svg:text')
.attr('x', 0)
.attr('y', 30)
.attr('class', 'id')
.append('svg:tspan')
.attr('x', 0)
.attr('dy', 5)
.text(function(d) { return d.name; })
.append('svg:tspan')
.attr('x', 0)
.attr('dy', 20)
.text(function(d) { return d.sname; })
.append('svg:tspan')
.attr('x', 0)
.attr('dy', 20)
.text(function(d) { return d.idcode; })
There are 3 lines separated with linebreak.
In Java
LocalDateTime firstOfWeek = LocalDateTime.now().with(ChronoField.DAY_OF_WEEK, 1).toLocalDate().atStartOfDay(); // 2020-06-08 00:00 MONDAY
LocalDateTime firstOfMonth = LocalDateTime.now().with(ChronoField.DAY_OF_MONTH , 1).toLocalDate().atStartOfDay(); // 2020-06-01 00:00
// Convert to milliseconds:
firstOfWeek.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli();
In Kotlin

I found a website offering a list of 20 distinctive colours: https://sashat.me/2017/01/11/list-of-20-simple-distinct-colors/

You can have a try!
It depends on wether the locatoin is detected by different DNS resolution from different locations, or by IP address that you are browsing from.
If its by DNS, you could just modify your hosts file to point at the server used in europe. Get your friend to ping the address, to see if its different from the one yours resolves to.
To browse from a different IP address:
You can rent a VPS server. You can use putty / SSH to act as a proxy. I use this from time to time to brows from the US using a VPS server I rent in the US.
Having an account on a remote host may or may not be enough. Sadly, my dreamhost account, even though I have ssh access, does not allow proxying.
byte[] buff = {1, -2, 5, 66};
for(byte c : buff) {
System.out.format("%d ", c);
}
System.out.println();
gets you
1 -2 5 66
? is called Ternary (conditional) operator : example
You could use a string stream and read the elements into the vector.
Here are many different examples...
A copy of one of the examples:
std::vector<std::string> split(const std::string& s, char seperator)
{
std::vector<std::string> output;
std::string::size_type prev_pos = 0, pos = 0;
while((pos = s.find(seperator, pos)) != std::string::npos)
{
std::string substring( s.substr(prev_pos, pos-prev_pos) );
output.push_back(substring);
prev_pos = ++pos;
}
output.push_back(s.substr(prev_pos, pos-prev_pos)); // Last word
return output;
}
In my experience, just pick a relatively high number (between 1024-65535) that you think is unlikely to be used by anything else. For example, port # 8080 and # 5555 are ones that I routinely use. Just pick a port number like this as opposed to just making the code randomly select it and then having to find the port number later is much easier for me.
For example, in my current ChatBot project:
port = 8080
In Java, integer literals are of type int by default. For some other types, you may suffix the literal with a case-insensitive letter like L
, D
, F
to specify a long, double, or float, respectively. Note it is common practice to use uppercase letters for better readability.
The Java Language Specification does not provide the same syntactic sugar for byte or short types. Instead, you may declare it as such using explicit casting:
byte foo = (byte)0;
short bar = (short)0;
In your setLongValue(100L)
method call, you don't have to necessarily include the L
suffix because in this case the int literal is automatically widened to a long. This is called widening primitive conversion in the Java Language Specification.
Don't waste your time, you can use Resource Bundle plugin in Eclipse
This one would always start with lowercase, and also strip non alphanumeric characters:
def camelCase(st):
output = ''.join(x for x in st.title() if x.isalnum())
return output[0].lower() + output[1:]
json.loads()
takes a JSON encoded string, not a filename. You want to use json.load()
(no s
) instead and pass in an open file object:
with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
data = json.load(jsonfile)
The open()
command produces a file object that json.load()
can then read from, to produce the decoded Python object for you. The with
statement ensures that the file is closed again when done.
The alternative is to read the data yourself and then pass it into json.loads()
.
On my case it was casing from Limits on Table Column Count and Row Size and doing changes described in this answer saved my day.
Add the following to the my.cnf file under [mysqld] section.
innodb_file_per_table
innodb_file_format = Barracuda
ALTER the table to use ROW_FORMAT=COMPRESSED.
ALTER TABLE table_name
ENGINE=InnoDB
ROW_FORMAT=COMPRESSED
KEY_BLOCK_SIZE=8;
I just like to use plain vanilla javascript to do this.
function isExists(selector){
return document.querySelectorAll(selector).length>0;
}
To run multiple commands just add &&
between two commands like this: command1 && command2
And if you want to run them in two different terminals then you do it like this:
gnome-terminal -e "command1" && gnome-terminal -e "command2"
This will open 2 terminals with command1
and command2
executing in them.
Hope this helps you.
It doesn't - the C# compiler does :)
So this code:
string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;
actually gets compiled as:
string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);
(Gah - intervening edit removed other bits accidentally.)
The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y
which then needs to be copied again as part of the concatenation of (x + y)
and z
. Instead, we get it all done in one go.
EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:
string x = "";
foreach (string y in strings)
{
x += y;
}
just ends up as equivalent to:
string x = "";
foreach (string y in strings)
{
x = string.Concat(x, y);
}
... so this does generate a lot of garbage, and it's why you should use a StringBuilder
for such cases. I have an article going into more details about the two which will hopefully answer further questions.

The quick solution is to store it in sharedPrefs and add this logic to onCreate
method in your MainActivity or class which is extending Application.
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(this, instanceIdResult -> {
String newToken = instanceIdResult.getToken();
Log.e("newToken", newToken);
getActivity().getPreferences(Context.MODE_PRIVATE).edit().putString("fb", newToken).apply();
});
Log.d("newToken", getActivity().getPreferences(Context.MODE_PRIVATE).getString("fb", "empty :("));
A better option is to create a service and keep inside a similar logic. Firstly create new Service
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onNewToken(String s) {
super.onNewToken(s);
Log.e("newToken", s);
getSharedPreferences("_", MODE_PRIVATE).edit().putString("fb", s).apply();
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
}
public static String getToken(Context context) {
return context.getSharedPreferences("_", MODE_PRIVATE).getString("fb", "empty");
}
}
And then add it to AndroidManifest file
<service
android:name=".MyFirebaseMessagingService"
android:stopWithTask="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
Finally, you are able to use a static method from your Service MyFirebaseMessagingService.getToken(Context);
Log.d("Firebase", "token "+ FirebaseInstanceId.getInstance().getToken());
It's still working when you are using older firebase library than version 17.x.x
Open Terminal and type:
pip config set global.target /Users/Bob/Library/Python/3.8/lib/python/site-packages
except instead of
/Users/Bob/Library/Python/3.8/lib/python/site-packages
you would use whatever directory you want.
As some people have mentioned, Javascript is the way to go. Bear in mind that the "validation" here is only by file extension, it won't validate that the file is a real excel spreadsheet!

Of course you could just use jQuery .fadeIn()
and .fadeOut()
functions, but the advantage of setting classes instead is in case you want to transition to a display value other than block
(as is the default with .fadeIn()
and .fadeOut()
).
Here I am transitioning to display flex
with a nice fade effect.
You're right that the SD Card directory is /sdcard
but you shouldn't be hard coding it. Instead, make a call to Environment.getExternalStorageDirectory()
to get the directory:
File sdDir = Environment.getExternalStorageDirectory();
If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
It turns out that OpenSSL is compiled and enabled in php 5.3 of XAMPP 1.7.2 and so no longer requires a separate extension dll.
However, you STILL need to enable it in your PHP.ini file the line extension=php_openssl.dll

I wrote a c++ program based on Win32 to write an assembly to the boot sector of a pen-drive. When the computer is booted from the pen-drive it executes the code successfully - have a look here C++ Program to write to the boot sector of a USB Pendrive
This program is a few lines that should be compiled on a compiler with windows compilation configured - such as a visual studio compiler - any available version.
Try this sample. It works for me.
public static void main(String[] args) {
Logger logger = Logger.getLogger("MyLog");
FileHandler fh;
try {
// This block configure the logger with handler and formatter
fh = new FileHandler("C:/temp/test/MyLogFile.log");
logger.addHandler(fh);
SimpleFormatter formatter = new SimpleFormatter();
fh.setFormatter(formatter);
// the following statement is used to log any messages
logger.info("My first log");
} catch (SecurityException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
logger.info("Hi How r u?");
}
Produces the output at MyLogFile.log
Apr 2, 2013 9:57:08 AM testing.MyLogger main
INFO: My first log
Apr 2, 2013 9:57:08 AM testing.MyLogger main
INFO: Hi How r u?
Edit:
To remove the console handler, use
logger.setUseParentHandlers(false);
since the ConsoleHandler is registered with the parent logger from which all the loggers derive.
Normally the ON clause comes from the mapping's join columns, but the JPA 2.1 draft allows for additional conditions in a new ON clause.
See,
http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Basic_JPA_Development/Querying/JPQL#ON
You want a parameter source:
Set<Integer> ids = ...;
MapSqlParameterSource parameters = new MapSqlParameterSource();
parameters.addValue("ids", ids);
List<Foo> foo = getJdbcTemplate().query("SELECT * FROM foo WHERE a IN (:ids)",
parameters, getRowMapper());
This only works if getJdbcTemplate()
returns an instance of type NamedParameterJdbcTemplate

tr
can be more concise for removing characters than sed
or awk
, especially when you want to remove different characters from a string.
Removing double quotes:
echo '"Hi"' | tr -d \"
# Produces Hi without quotes
Removing different kinds of brackets:
echo '[{Hi}]' | tr -d {}[]
# Produces Hi without brackets
-d
stands for "delete".
This should get you started:

In a nutshell :
-> Git Merge: It will simply merge your local changes and remote changes, and that will create another commit history record
-> Git Rebase: It will put your changes above all new remote changes, and rewrite commit history, so your commit history will be much cleaner than git merge. Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.

Sorry I know this is old but why not style all tr elements the way you want all except the first and the use the psuedo class :first-child where you revoke what you specified for all tr elements.
Better descriped by this example:
tr {
border-top: 1px solid;
}
tr:first-child {
border-top: none;
}

No, APK Manager decompiles the .dex
file into .smali
and binary .xml
to human readable xml.
The sequence (based on APK Manager 4.9) is 22 to select the package, and then 9 to decompile it. If you press 1 instead of 9, then you will just unpack it (useful only if you want to exchange .png images).
There is no tool available to decompile back to .java
files and most probably it won't be any. There is an alternative, which is using dex2jar to transform the dex file in to a .class
file, and then use a jar decompiler (such as the free jd-gui) to plain text java. The process is far from optimal, though, and it won't generate working code, but it's decent enough to be able to read it.
dex2jar: https://github.com/pxb1988/dex2jar
jd-gui: http://jd.benow.ca/
Edit: I knew there was somewhere here in SO a question with very similar answers... decompiling DEX into Java sourcecode
Probably you get the same error message if the standalone.xml in your standalone/configuration folder cannot be found. At least I have the same error when using a WildFly 14.0.1:
@Comment for ID:14. It's for me rather easier to write:
out.append it
instead of
out.println it
println did on my machine only write the first file of the ArrayList, with append I get the whole List written into the file.
Kindly anyway for the quick-and-dirty-solution.
List<String> names = Arrays.asList("2","@2234","21","11");
Alternatively you can grant the user DROP_ANY_TABLE
privilege if need be and the procedure will run as is without the need for any alteration. Dangerous maybe but depends what you're doing :)
If that's a global object, you can use if (!window.maybeObject)
There are already many good answers to the part "what is uintptr_t data type". I will try to address the "what it can be used for?" part in this post.
Primarily for bitwise operations on pointers. Remember that in C++ one cannot perform bitwise operations on pointers. For reasons see Why can't you do bitwise operations on pointer in C, and is there a way around this?
Thus in order to do bitwise operations on pointers one would need to cast pointers to type unitpr_t and then perform bitwise operations.
Here is an example of a function that I just wrote to do bitwise exclusive or of 2 pointers to store in a XOR linked list so that we can traverse in both directions like a doubly linked list but without the penalty of storing 2 pointers in each node.
template <typename T>
T* xor_ptrs(T* t1, T* t2)
{
return reinterpret_cast<T*>(reinterpret_cast<uintptr_t>(t1)^reinterpret_cast<uintptr_t>(t2));
}
I completely agree with mercenary's answer posted above and created this function for me which works for me. It's not an answer, it's a comment on above post by mercenary
function openWindowWithPostRequest() {
var winName='MyWindow';
var winURL='search.action';
var windowoption='resizable=yes,height=600,width=800,location=0,menubar=0,scrollbars=1';
var params = { 'param1' : '1','param2' :'2'};
var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", winURL);
form.setAttribute("target",winName);
for (var i in params) {
if (params.hasOwnProperty(i)) {
var input = document.createElement('input');
input.type = 'hidden';
input.name = i;
input.value = params[i];
form.appendChild(input);
}
}
document.body.appendChild(form);
window.open('', winName,windowoption);
form.target = winName;
form.submit();
document.body.removeChild(form);
}
I added a parameterless constructor to the model inside of DOMAIN Folder, and the problem is solved.

If you want a UTF8 string, where every byte is correct ('Ö' -> [195, 0] , [150, 0]), you can use the followed:
public static string Utf16ToUtf8(string utf16String)
{
/**************************************************************
* Every .NET string will store text with the UTF16 encoding, *
* known as Encoding.Unicode. Other encodings may exist as *
* Byte-Array or incorrectly stored with the UTF16 encoding. *
* *
* UTF8 = 1 bytes per char *
* ["100" for the ansi 'd'] *
* ["206" and "186" for the russian '?'] *
* *
* UTF16 = 2 bytes per char *
* ["100, 0" for the ansi 'd'] *
* ["186, 3" for the russian '?'] *
* *
* UTF8 inside UTF16 *
* ["100, 0" for the ansi 'd'] *
* ["206, 0" and "186, 0" for the russian '?'] *
* *
* We can use the convert encoding function to convert an *
* UTF16 Byte-Array to an UTF8 Byte-Array. When we use UTF8 *
* encoding to string method now, we will get a UTF16 string. *
* *
* So we imitate UTF16 by filling the second byte of a char *
* with a 0 byte (binary 0) while creating the string. *
**************************************************************/
// Storage for the UTF8 string
string utf8String = String.Empty;
// Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);
// Fill UTF8 bytes inside UTF8 string
for (int i = 0; i < utf8Bytes.Length; i++)
{
// Because char always saves 2 bytes, fill char with 0
byte[] utf8Container = new byte[2] { utf8Bytes[i], 0 };
utf8String += BitConverter.ToChar(utf8Container, 0);
}
// Return UTF8
return utf8String;
}
In my case the DLL request is a UTF8 string too, but unfortunately the UTF8 string must be interpreted with UTF16 encoding ('Ö' -> [195, 0], [19, 32]). So the ANSI '–' which is 150 has to be converted to the UTF16 '–' which is 8211. If you have this case too, you can use the following instead:
public static string Utf16ToUtf8(string utf16String)
{
// Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);
// Return UTF8 bytes as ANSI string
return Encoding.Default.GetString(utf8Bytes);
}
Or the Native-Method:
[DllImport("kernel32.dll")]
private static extern Int32 WideCharToMultiByte(UInt32 CodePage, UInt32 dwFlags, [MarshalAs(UnmanagedType.LPWStr)] String lpWideCharStr, Int32 cchWideChar, [Out, MarshalAs(UnmanagedType.LPStr)] StringBuilder lpMultiByteStr, Int32 cbMultiByte, IntPtr lpDefaultChar, IntPtr lpUsedDefaultChar);
public static string Utf16ToUtf8(string utf16String)
{
Int32 iNewDataLen = WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, utf16String.Length, null, 0, IntPtr.Zero, IntPtr.Zero);
if (iNewDataLen > 1)
{
StringBuilder utf8String = new StringBuilder(iNewDataLen);
WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, -1, utf8String, utf8String.Capacity, IntPtr.Zero, IntPtr.Zero);
return utf8String.ToString();
}
else
{
return String.Empty;
}
}
If you need it the other way around, see Utf8ToUtf16. Hope I could be of help.
Andy, to delete file on remote system you need to use (channelExec)
of JSch and pass unix/linux commands to delete it.
Optional should mainly be used for results of Services anyway. In the service you know what you have at hand and return Optional.of(someValue) if you have a result and return Optional.empty() if you don't. In this case, someValue should never be null and still, you return an Optional.
You code is correct. replace items with .items as below
<script>
var n = $(".items").css("left");
if(n == -900){
$(".items span").fadeOut("slow");
}
</script>
Code Example : Reading data from DataGridView and storing it in an array
int[,] n = new int[3, 19];
for (int i = 0; i < (StartDataView.Rows.Count - 1); i++)
{
for (int j = 0; j < StartDataView.Columns.Count; j++)
{
if(this.StartDataView.Rows[i].Cells[j].Value.ToString() != string.Empty)
{
try
{
n[i, j] = int.Parse(this.StartDataView.Rows[i].Cells[j].Value.ToString());
}
catch (Exception Ee)
{ //get exception of "null"
MessageBox.Show(Ee.ToString());
}
}
}
}
Try checking for duplicates with a .contains()
method on the ArrayList, before adding a new element.
It would look something like this
if(!list.contains(data))
list.add(data);
That should prevent duplicates in the list, as well as not mess up the order of elements, like people seem to look for.
The accepted answer is not the right one, because the question is not about renaming a file into a file, but moving many files into a directory. shutil.move
will do the work, but for this purpose os.rename
is useless (as stated on comments) because destination must have an explicit file name.
You can use a .Net environment Visual studio, Take a look at the differences with the PC version.
A lighter editor would be Visual Code
Alternatives :
Installing the Mono Project runtime . It allows you to re-compile the code and run it on a Mac, but this requires various alterations to the codebase, as the fuller .Net Framework is not available. (Also, WPF applications aren't supported here either.)
Virtual machine (VMWare Fusion perhaps)
Update your codebase to .Net Core, (before choosing this option take a look at this migration process)
.Net Core 3.1 is an open-source, free and available on Window, MacOs and Linux
As of September 14, a release candidate 1 of .Net Core 5.0 has been deployed on Window, MacOs and Linux.

I'm not 100% sure, but I believe the error was caused by some client-side JavaScript that was turning exports into an object. Some code in the Slick plugin (see below) calls the require function if exports is not undefined.
Here's the portion of code I had to change in slick.js. You can see I am just commenting out the if statements, and, instead, I'm just calling factory(jQuery).
;(function(factory) {
console.log('slick in factory', define, 'exports', exports, 'factory', factory);
'use strict';
// if (typeof define === 'function' && define.amd) {
// define(['jquery'], factory);
// } else if (typeof exports !== 'undefined') {
// module.exports = factory(require('jquery'));
// } else {
// factory(jQuery);
// }
factory(jQuery);
}

The problem might originate from a macro instruction in SDL_main.h
In that macro your main(){} is renamed to SDL_main(){} because SDL needs its own main(){} on some of the many platforms they support, so they change yours. Mostly it achieves their goal, but on my platform it created problems, rather than solved them. I added a 2nd line in SDL_main.h, and for me all problems were gone.
#define main SDL_main //Original line. Renames main(){} to SDL_main(){}.
#define main main //Added line. Undo the renaming.
If you don't like the compiler warning caused by this pair of lines, comment both lines out.
If your code is in WinApp(){} you don't have this problem at all. This answer only might help if your main code is in main(){} and your platform is similar to mine.
I have: Visual Studio 2019, Windows 10, x64, writing a 32 bit console app that opens windows using SDL2.0 as part of a tutorial.

Since Java 8, the answer by @ZouZou using the Collectors.toMap
collector is certainly the idiomatic way to solve this problem.
And as this is such a common task, we can make it into a static utility.
That way the solution truly becomes a one-liner.
/**
* Returns a map where each entry is an item of {@code list} mapped by the
* key produced by applying {@code mapper} to the item.
*
* @param list the list to map
* @param mapper the function to produce the key from a list item
* @return the resulting map
* @throws IllegalStateException on duplicate key
*/
public static <K, T> Map<K, T> toMapBy(List<T> list,
Function<? super T, ? extends K> mapper) {
return list.stream().collect(Collectors.toMap(mapper, Function.identity()));
}
And here's how you would use it on a List<Student>
:
Map<Long, Student> studentsById = toMapBy(students, Student::getId);
Using one of the subsets method in this question
var list = new List<KeyValuePair<string, int>>() {
new KeyValuePair<string, int>("A", 1),
new KeyValuePair<string, int>("B", 0),
new KeyValuePair<string, int>("C", 0),
new KeyValuePair<string, int>("D", 2),
new KeyValuePair<string, int>("E", 8),
};
int input = 11;
var items = SubSets(list).FirstOrDefault(x => x.Sum(y => y.Value)==input);

a full console application:
using System;
using System.Collections.Generic;
using System.Linq;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
var list = new List<KeyValuePair<string, int>>() {
new KeyValuePair<string, int>("A", 1),
new KeyValuePair<string, int>("B", 2),
new KeyValuePair<string, int>("C", 3),
new KeyValuePair<string, int>("D", 4),
new KeyValuePair<string, int>("E", 5),
new KeyValuePair<string, int>("F", 6),
};
int input = 12;
var alternatives = list.SubSets().Where(x => x.Sum(y => y.Value) == input);
foreach (var res in alternatives)
{
Console.WriteLine(String.Join(",", res.Select(x => x.Key)));
}
Console.WriteLine("END");
Console.ReadLine();
}
}
public static class Extenions
{
public static IEnumerable<IEnumerable<T>> SubSets<T>(this IEnumerable<T> enumerable)
{

for (ulong i = 0; i < upper; i++)
{
List<T> l = new List<T>(list.Count);

ReSharper does a great job of finding unused code.
In the VS IDE, you can right click on the definition and choose 'Find All References', although this only works at the solution level.
IE8/9 render the non-breaking hyphen mentioned in CanSpice's answer longer than a typical hyphen. It is the length of an en-dash instead of a typical hyphen. This display difference was a deal breaker for me.
As I could not use the CSS answer specified by Deb I instead opted to use no break tags.
<nobr>e-mail</nobr>
In addition I found a specific scenario that caused IE8/9 to break on a hyphen.
IE renders it like this.
The following code reproduces the problem pictured above. I had to use a meta tag to force rendering to IE9 as IE10 has fixed the issue. No fiddle because it does not support meta tags.
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=9" />
<meta charset="utf-8"/>
<style>
body { padding: 20px; }
div { width: 300px; border: 1px solid gray; }
</style>
</head>
<body>
<div>
<p>If there is a - and words are separated by the whitespace code &nbsp; then IE will wrap on the dash.</p>
</div>
</body>
</html>
Within Crystal, you can do it by creating a formula that uses the ToNumber
function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:
If NumericText ({field}) then ToNumber ({field}) else 0
Alternatively, you might find it easier to convert the field's datatype within the query used in the report.
render the child components not at once but after some delay .
The question says delay render but if it is ok to render but hide...
You can render the components from a map straight away but use css animation to delay them being shown.
@keyframes Jumpin {
0% { opacity: 0; }
50% { opacity: 0; }
100% { opacity: 1; }
}
// Sass loop code
@for $i from 2 through 10 {
.div .div:nth-child(#{$i}) {
animation: Jumpin #{$i * 0.35}s cubic-bezier(.9,.03,.69,.22);
}
}
The child divs now follow each other with a slight delay.
Inline tag is used to add another src of document to the current html element.
In your case an video of a youtube and we need to specify the html type(4 or 5) to the browser externally to the link
so add ?html=5 to the end of the link.. :)
If you're using Bash, you can also do the following if, let's say, you want to remove the directory /home/wrong/dir/
from your PATH
variable:
PATH=`echo $PATH | sed -e 's/:\/home\/wrong\/dir\/$//'`
To do this in t-sql, you can use the following system stored procedures to schedule a daily job. This example schedules daily at 1:00 AM. See Microsoft help for details on syntax of the individual stored procedures and valid range of parameters.

Limiting the length of the input is definitely easier. You could accept an arbitrarily-long input by using a loop, reading in a bit at a time, re-allocating space for the string as necessary...
But that's a lot of work, so most C programmers just chop off the input at some arbitrary length. I suppose you know this already, but using fgets() isn't going to allow you to accept arbitrary amounts of text - you're still going to need to set a limit.
As Darren commented, Apache don't understand php.ini
relative paths in Windows.
To fix it, change the relative paths in your php.ini
to absolute paths.
extension_dir="C:\full\path\to\php\ext\dir"
You could also look at it from the other way around...
from urlparse import urlparse
[el for el in ['text1', 'FTP://somewhere.com', 'text2', 'http://blah.com:8080/foo/bar#header'] if not urlparse(el).scheme]
Try this, you can change for even when you want. this example use jQuery.
$('#iframe').live('mousemove', function (event) {
var theFrame = $(this, parent.document.body);
this.height($(document.body).height() - 350);
});
you can Add contextual classes to every single row as follows:
<tr class="table-success"></tr>
<tr class="table-error"></tr>
<tr class="table-warning"></tr>
<tr class="table-info"></tr>
<tr class="table-danger"></tr>
You can also add them to table data same as above
You can set your table size by setting classes as table-sm and so on.
You can add custom classes and add your own styling:
<table class="table">
<thead style = "color:red;background-color:blue">
<tr>
<th></th>
<th>First Name</th>
<th>Last Name</th>
</tr>
</thead>
<tbody>
<tr>
<td>Asdf</td>
<td>qwerty</td>
</tr>
</tbody>
</table>
This way you can add custom styling. I have showed inline styling just for example how it works, you can add classes and call them in your css as well.
Try this (but please use buttons for such cases if you don't have a valid href
value for graceful degradation)
<a href="#" onclick="callmymethod(24); return false;">Call</a>
You can use OR()
to group expressions (as well as AND()
):
=IF(OR(condition1, condition2), true, false)
=IF(AND(condition1, condition2), true, false)
So if you wanted to test for "cat" and "22":
=IF(AND(SEARCH("cat",a1),SEARCH("22",a1)),"cat and 22","none")
How about:

If you want one md5sum spanning the whole directory, I would do something like
cat *.py | md5sum
A BehaviorSubject holds one value. When it is subscribed it emits the value immediately. A Subject doesn't hold a value.
Subject example (with RxJS 5 API):
const subject = new Rx.Subject();
subject.next(1);
subject.subscribe(x => console.log(x));
Console output will be empty
BehaviorSubject example:
const subject = new Rx.BehaviorSubject(0);
subject.next(1);
subject.subscribe(x => console.log(x));
Console output: 1
In addition:
BehaviorSubject
should be created with an initial value: new Rx.BehaviorSubject(1)
ReplaySubject
if you want the subject to hold more than one valueConsider:
Function GetFolder() As String
Dim fldr As FileDialog
Dim sItem As String
Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
With fldr
.Title = "Select a Folder"
.AllowMultiSelect = False
.InitialFileName = Application.DefaultFilePath
If .Show <> -1 Then GoTo NextCode
sItem = .SelectedItems(1)
End With
NextCode:
GetFolder = sItem
Set fldr = Nothing
End Function
This code was adapted from Ozgrid
and as jkf points out, from Mr Excel
Several of the responses rely on an exception being thrown and having it handled in the OnException override. In my case, I wanted to return statuses such as bad request if the user, say, had passed in a bad ID. What works for me is to use the ControllerContext:
var jsonResult = new JsonResult { JsonRequestBehavior = JsonRequestBehavior.AllowGet, Data = "whoops" };
ControllerContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.BadRequest;
return jsonResult;
For me, I was getting this error message when using PUT
or DELETE
to WebAPI. I also tried re-registering .NET Framework as suggested but to no avail.
I was able to fix this by disabling WebDAV for my individual application pool, this stopped the 'bad module' error when using PUT
or DELETE
.

For anyone who's looking to do this in 2018, I've got a much better and simpler solution then all the old stuff posted here. You can make a nice looking drag & drop box with just vanilla HTML, JavaScript and CSS.
(Only works in Chrome so far)
Let's start with the HTML.
<div>
<input type="file" name="file" id="file" class="file">
<span id="value"></span>
</div>
Then we'll get to the styling.
.file {
width: 400px;
height: 50px;
background: #171717;
padding: 4px;
border: 1px dashed #333;
position: relative;
cursor: pointer;
}
.file::before {
content: '';
position: absolute;
background: #171717;
font-size: 20px;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 100%;
height: 100%;
}
.file::after {
content: 'Drag & Drop';
position: absolute;
color: #808080;
font-size: 20px;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
After you've done this it already looks fine. But I imagine you'd like to see what file you actaully uploaded, so we're going to do some JavaScript. Remember that pfp-value span? That's where we'll print out the file name.
let file = document.getElementById('file');
file.addEventListener('change', function() {
if(file && file.value) {
let val = file.files[0].name;
document.getElementById('value').innerHTML = "Selected" + val;
}
});
And that's it.
How about something like this?
val newDF = df.filter($"B" === "").take(1) match {
case Array() => df
case _ => df.withColumn("D", $"B" === "")
}
Using take(1)
should have a minimal hit
trigger('slideIn', [
state('*', style({ 'overflow-y': 'hidden' })),
state('void', style({ 'overflow-y': 'hidden' })),
transition('* => void', [
style({ height: '*' }),
animate(250, style({ height: 0 }))
]),
transition('void => *', [
style({ height: '0' }),
animate(250, style({ height: '*' }))
])
])
Late response but this is what I ended up doing. If you want to run your curl commands very similarly as you run them on linux and you have windows 10 or latter do this:
public static string ExecuteCurl(string curlCommand, int timeoutInSeconds=60)
{
if (string.IsNullOrEmpty(curlCommand))
return "";
curlCommand = curlCommand.Trim();
// remove the curl keworkd
if (curlCommand.StartsWith("curl"))
{
curlCommand = curlCommand.Substring("curl".Length).Trim();
}
// this code only works on windows 10 or higher
{
curlCommand = curlCommand.Replace("--compressed", "");
// windows 10 should contain this file
var fullPath = System.IO.Path.Combine(Environment.SystemDirectory, "curl.exe");
if (System.IO.File.Exists(fullPath) == false)
{
if (Debugger.IsAttached) { Debugger.Break(); }
throw new Exception("Windows 10 or higher is required to run this application");
}
// on windows ' are not supported. For example: curl 'http://ublux.com' does not work and it needs to be replaced to curl "http://ublux.com"
List<string> parameters = new List<string>();
// separate parameters to escape quotes
try
{
Queue<char> q = new Queue<char>();
foreach (var c in curlCommand.ToCharArray())
{
q.Enqueue(c);
}
StringBuilder currentParameter = new StringBuilder();
void insertParameter()
{
var temp = currentParameter.ToString().Trim();
if (string.IsNullOrEmpty(temp) == false)
{
parameters.Add(temp);
}
currentParameter.Clear();
}
while (true)
{
if (q.Count == 0)
{
insertParameter();
break;
}
char x = q.Dequeue();
if (x == '\'')
{
insertParameter();
// add until we find last '
while (true)
{
x = q.Dequeue();
// if next 2 characetrs are \'
if (x == '\\' && q.Count > 0 && q.Peek() == '\'')
{
currentParameter.Append('\'');
q.Dequeue();
continue;
}
if (x == '\'')
{
insertParameter();
break;
}
currentParameter.Append(x);
}
}
else if (x == '"')
{
insertParameter();
// add until we find last "
while (true)
{
x = q.Dequeue();
// if next 2 characetrs are \"
if (x == '\\' && q.Count > 0 && q.Peek() == '"')
{
currentParameter.Append('"');
q.Dequeue();
continue;
}
if (x == '"')
{
insertParameter();
break;
}
currentParameter.Append(x);
}
}
else
{
currentParameter.Append(x);
}
}
}
catch
{
if (Debugger.IsAttached) { Debugger.Break(); }
throw new Exception("Invalid curl command");
}
StringBuilder finalCommand = new StringBuilder();
foreach (var p in parameters)
{
if (p.StartsWith("-"))
{
finalCommand.Append(p);
finalCommand.Append(" ");
continue;
}
var temp = p;
if (temp.Contains("\""))
{
temp = temp.Replace("\"", "\\\"");
}
if (temp.Contains("'"))
{
temp = temp.Replace("'", "\\'");
}
finalCommand.Append($"\"{temp}\"");
finalCommand.Append(" ");
}
using (var proc = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "curl.exe",
Arguments = finalCommand.ToString(),
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
CreateNoWindow = true,
WorkingDirectory = Environment.SystemDirectory
}
})
{
proc.Start();
proc.WaitForExit(timeoutInSeconds*1000);
return proc.StandardOutput.ReadToEnd();
}
}
}
The reason why the code is a little bit long is because windows will give you an error if you execute a single quote. In other words, the command curl 'https://google.com'
will work on linux and it will not work on windows. Thanks to that method I created you can use single quotes and run your curl commands exactly as you run them on linux. This code also checks for escaping characters such as \'
and \"
.
For example use this code as
var output = ExecuteCurl(@"curl 'https://google.com' -H 'Accept: application/json, text/javascript, */*; q=0.01'");
If you where to run that same string agains C:\Windows\System32\curl.exe
it will not work because for some reason windows does not like single quotes.
I guess the only way to do this is by utilizing reusable fragments:
fragment UserFragment on Users {
id
username
count
}
FetchUsers {
users(id: "2") {
...UserFragment
}
}
subscribe() -Invokes an execution of an Observable and registers Observer handlers for notifications it will emit. -Observable- representation of any set of values over any amount of time.
I recommend more understanding way using extension method:
public static class KeyValuePairExtensions
{
public static bool IsNull<T, TU>(this KeyValuePair<T, TU> pair)
{
return pair.Equals(new KeyValuePair<T, TU>());
}
}
And then just use:
var countries = new Dictionary<string, string>
{
{"cz", "prague"},
{"de", "berlin"}
};
var country = countries.FirstOrDefault(x => x.Key == "en");
if(country.IsNull()){
}
Use 3 backslashes to escape spaces in names of directories:
scp user@host:/path/to/directory\\\ with\\\ spaces/file ~/Downloads
should copy to your Downloads
directory the file
from the remote directory called directory with spaces
.
if not exists (select * from sysobjects where name='cars' and xtype='U')
create table cars (
Name varchar(64) not null
)
go
The above will create a table called cars
if the table does not already exist.
The way to do this using the Extention Methods, instead of the linq query syntax would be like this:
var results = workOrders.Join(plans,
wo => wo.WorkOrderNumber,
p => p.WorkOrderNumber,
(order,plan) => new {order.WorkOrderNumber, order.WorkDescription, plan.ScheduledDate}
);
SELECT CASE DATEPART(WEEKDAY,GETDATE())
WHEN 1 THEN 'SUNDAY'
WHEN 2 THEN 'MONDAY'
WHEN 3 THEN 'TUESDAY'
WHEN 4 THEN 'WEDNESDAY'
WHEN 5 THEN 'THURSDAY'
WHEN 6 THEN 'FRIDAY'
WHEN 7 THEN 'SATURDAY'
END
I spent some time trying to find a nice function to wrap a solution. Anyway, ended up with this which I feel is a better solutions when loading multiple content on a single page or across a site.
Function:
function ifViewLoadContent(elem, LoadContent)
{
var top_of_element = $(elem).offset().top;
var bottom_of_element = $(elem).offset().top + $(elem).outerHeight();
var bottom_of_screen = $(window).scrollTop() + window.innerHeight;
var top_of_screen = $(window).scrollTop();
if((bottom_of_screen > top_of_element) && (top_of_screen < bottom_of_element)){
if(!$(elem).hasClass("ImLoaded")) {
$(elem).load(LoadContent).addClass("ImLoaded");
}
}
else {
return false;
}
}
You can then call the function using window on scroll (for example, you could also bind it to a click etc. as I also do, hence the function):
To use:
$(window).scroll(function (event) {
ifViewLoadContent("#AjaxDivOne", "someFile/somecontent.html");
ifViewLoadContent("#AjaxDivTwo", "someFile/somemorecontent.html");
});
This approach should also work for scrolling divs etc. I hope it helps, in the question above you could use this approach to load your content in sections, maybe append and thereby dribble feed all that image data rather than bulk feed.
I used this approach to reduce the overhead on https://www.taxformcalculator.com. It died the trick, if you look at the site and inspect element etc. you can see impact on page load in Chrome (as an example).
Some good solutions here but this one doesn't need SVG, preserves the border via outline
and sets it flush on the button.

outline-offset: -1px;_x000D_
}

I had similar Issue where we have GenericResponse object containing list of values
ResponseEntity<ResponseDTO> responseEntity = restTemplate.exchange(

Under MYSQL 5.7, If you are using mysql for development purpose, just :
1.kill mysql :
$ sudo service mysql stop
2.start mysql under --skip-grant-tables mode:
$ sudo mysqld_safe --skip-grant-tables
and, further, you could try to change the user table under "skip-grant-table" mode, however I failed.
so, this is just a workaround.

Mostly the image is not displayed because you URL contains spaces. In your case you almost did everything correct. Except one thing - you have not added single quotes like you do if you specify background-image in css I.e.
.bg-img { \/ \/
background-image: url('http://...');
}
To do so escape quot character in HTML via \'
\/ \/
<div [ngStyle]="{'background-image': 'url(\''+ item.color.catalogImageLink + '\')'}"></div>
If you go the binary serialization route, Consider the speed at which a particular member of the datum needs to be accessed. If it is only a small collection, loading the whole file will make sense, but if it will be large, you might also consider an index file.
Tracking Account Properties/fields that are located at a specific address within the file can help you speed up access time, especially if you optimize that index file based on key usage. (possibly even when you write to disk.)
String mQuery = "SELECT Name,Family From tblName";
Cursor mCur = db.rawQuery(mQuery, new String[]{});
mCur.moveToFirst();
while ( !mCur.isAfterLast()) {
String name= mCur.getString(mCur.getColumnIndex("Name"));
String family= mCur.getString(mCur.getColumnIndex("Family"));
mCur.moveToNext();
}
Name and family are your result

Just for completeness, there has recently been a question on the Jython mailinglist where one of the answers referred to this thread.
The question was how to call a Python script that is contained in a .jar file from within Jython, the suggested answer is as follows (with "InputStream" as explained in one of the answers above:

if you do not have any database in your application simply disable the auto-config of datasource by adding below annotation.

I know it's old post, but I thought this is a good addition:
You can use List<T>.ConvertAll<TOutput>
List<int> integers = strings.ConvertAll(s => Int32.Parse(s));
This is the shortest version I could find,saving/hiding an extra conversion:
pil_image = PIL.Image.open('image.jpg')
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)
If reading a file from a URL:
import cStringIO
import urllib
file = cStringIO.StringIO(urllib.urlopen(r'http://stackoverflow.com/a_nice_image.jpg').read())
pil_image = PIL.Image.open(file)
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)
Here is an alternative programming solution that may work for others who use MyISAM IF (important) you don't care if an update has happened during the middle of the queries. As we know MyISAM can cause table level locks, especially if you have an update pending which will get locked, and then other select queries behind this update get locked too.
So this method won't prevent a lock, but it will make a lot of tiny locks, so as not to hang a website for example which needs a response within a very short frame of time.
The idea here is we grab a range based on an index which is quick, then we do our match from that query only, so it's in smaller batches. Then we move down the list onto the next range and check them for our match.
Example is in Perl with a bit of pseudo code, and traverses high to low.
# object_id must be an index so it's fast
# First get the range of object_id, as it may not start from 0 to reduce empty queries later on.
my ( $first_id, $last_id ) = $db->db_query_array(
sql => q{ SELECT MIN(object_id), MAX(object_id) FROM mytable }
);
my $keep_running = 1;
my $step_size = 1000;
my $next_id = $last_id;
while( $keep_running ) {
my $sql = q{
SELECT object_id, created, status FROM
( SELECT object_id, created, status FROM mytable AS is1 WHERE is1.object_id <= ? ORDER BY is1.object_id DESC LIMIT ? ) AS is2
WHERE status='live' ORDER BY object_id DESC
};
my $sth = $db->db_query( sql => $sql, args => [ $step_size, $next_id ] );
while( my ($object_id, $created, $status ) = $sth->fetchrow_array() ) {
$last_id = $object_id;
## do your stuff
}
if( !$last_id ) {
$next_id -= $step_size; # There weren't any matched in the range we grabbed
} else {
$next_id = $last_id - 1; # There were some, so we'll start from that.
}
$keep_running = 0 if $next_id < 1 || $next_id < $first_id;
}

Context
represents a handle to get environment data .Context
class itself is declared as abstract, whose implementation is provided by the android OS.Context

In later versions (tested with TensorFlow 1.14) there's a more numpy-like way to get the shape of a tensor. You can use tensor.shape
to get the shape of the tensor.
tensor_shape = tensor.shape
print(tensor_shape)
Don't forget to inject $location
into controller.
You can also write a custom query using @Query
@Query(value = "from EntityClassTable t where yourDate BETWEEN :startDate AND :endDate")
public List<EntityClassTable> getAllBetweenDates(@Param("startDate")Date startDate,@Param("endDate")Date endDate);
For Kotlin users (activity as AppCompatActivity).supportActionBar?.show()
for superclasses with many members I would suggest you to use @Delegate
@Data
public class A {
@Delegate public class AInner{
private final int x;
private final int y;
}
}
@Data
@EqualsAndHashCode(callSuper = true)
public class B extends A {
private final int z;
public B(A.AInner a, int z) {
super(a);
this.z = z;
}
}
I think you can use CHECK constraint - it is exactly what it was invented for.
ALTER TABLE someTable
ADD CONSTRAINT someField_check CHECK (ISNUMERIC(someField) = 1) ;
My previous answer (also right by may be a bit overkill):
I think the right way is to use INSTEAD OF trigger to prevent the wrong data from being inserted (rather than deleting it post-factum)

Should you run into "linear" vs "nonlinear" RGB, here's part of an old note to myself on this. Repeat, in practice you won't see much difference.
In color science, the common RGB values, as in html rgb( 10%, 20%, 30% ), are called "nonlinear" or Gamma corrected. "Linear" values are defined as
Rlin = R^gamma, Glin = G^gamma, Blin = B^gamma
where gamma is 2.2 for many PCs. The usual R G B are sometimes written as R' G' B' (R' = Rlin ^ (1/gamma)) (purists tongue-click) but here I'll drop the '.
Brightness on a CRT display is proportional to RGBlin = RGB ^ gamma, so 50% gray on a CRT is quite dark: .5 ^ 2.2 = 22% of maximum brightness. (LCD displays are more complex; furthermore, some graphics cards compensate for gamma.)
To get the measure of lightness called L*
from RGB,
first divide R G B by 255, and compute
Y = .2126 * R^gamma + .7152 * G^gamma + .0722 * B^gamma
This is Y
in XYZ color space; it is a measure of color "luminance".
(The real formulas are not exactly x^gamma, but close;
stick with x^gamma for a first pass.)
Finally,
L* = 116 * Y ^ 1/3 - 16
