If you don't see log4net.dll in %systemdrive%\windows\assembly\
on the machine you are attempting to deploy it on, it is likely you haven't successfully installed the redistributable for Crystal Reports for .Net Framework 4.0
Install (or reinstall) the latest service pack from http://scn.sap.com/docs/DOC-7824 (SAP Crystal Reports, developer version for Microsoft Visual Studio Updates & Runtime Downloads)
That runtime distribution should add log4net to the GAC along with a bunch of CrystalDecisions dll's
I was not getting the error on 32-bit machines but was on 64-bit so I changed the target platform from x86 to Any CPU and it resolved the issue.
You would need to use the async BeginConnect
method of TcpClient
instead of attempting to connect synchronously, which is what the constructor does. Something like this:
var client = new TcpClient();
var result = client.BeginConnect("remotehost", this.Port, null, null);
var success = result.AsyncWaitHandle.WaitOne(TimeSpan.FromSeconds(1));
if (!success)
{
throw new Exception("Failed to connect.");
}
// we have connected
client.EndConnect(result);

I ran a benchmarking analysis and list(mvv_count_df.select('mvv').toPandas()['mvv'])
is the fastest method. I'm very surprised.
I ran the different approaches on 100 thousand / 100 million row datasets using a 5 node i3.xlarge cluster (each node has 30.5 GBs of RAM and 4 cores) with Spark 2.4.5. Data was evenly distributed on 20 snappy compressed Parquet files with a single column.
Here's the benchmarking results (runtimes in seconds):
+-------------------------------------------------------------+---------+-------------+
| Code | 100,000 | 100,000,000 |
+-------------------------------------------------------------+---------+-------------+
| df.select("col_name").rdd.flatMap(lambda x: x).collect() | 0.4 | 55.3 |
| list(df.select('col_name').toPandas()['col_name']) | 0.4 | 17.5 |
| df.select('col_name').rdd.map(lambda row : row[0]).collect()| 0.9 | 69 |
| [row[0] for row in df.select('col_name').collect()] | 1.0 | OOM |
| [r[0] for r in mid_df.select('col_name').toLocalIterator()] | 1.2 | * |
+-------------------------------------------------------------+---------+-------------+
* cancelled after 800 seconds
Golden rules to follow when collecting data on the driver node:
toPandas
was significantly improved in Spark 2.3. It's probably not the best approach if you're using a Spark version earlier than 2.3.

Try with enabling the sub-thread as daemon-thread.
Recommended:
from threading import Thread
t = Thread(target=<your-method>)
t.daemon = True # This thread dies when main thread (only non-daemon thread) exits.
t.start()
Inline:
t = Thread(target=<your-method>, daemon=True).start()
Old API:
t.setDaemon(True)
t.start()
When your main thread terminates ("i.e. when I press Ctrl+C"), other threads will also be killed by the instructions above.

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute
<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>
Inside the controller:
vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
vm.zoneDropdown = $customService.getZone();
}
And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):
<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
<li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">

Here's a quote from a recent blog post from Dare Obasanjo.
SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle.
However the most notable similarity is that just like most of us can’t really take advantage of the benefits of a manual transmission vehicle because the majority of our driving is sitting in traffic on the way to and from work, there is a similar harsh reality in that most sites aren’t at Google or Facebook’s scale and thus have no need for a Bigtable or Cassandra.
To which I can add only that switching from MySQL, where you have at least some experience, to CouchDB, where you have no experience, means you will have to deal with a whole new set of problems and learn different concepts and best practices. While by itself this is wonderful (I am playing at home with MongoDB and like it a lot), it will be a cost that you need to calculate when estimating the work for that project, and brings unknown risks while promising unknown benefits. It will be very hard to judge if you can do the project on time and with the quality you want/need to be successful, if it's based on a technology you don't know.
Now, if you have on the team an expert in the NoSQL field, then by all means take a good look at it. But without any expertise on the team, don't jump on NoSQL for a new commercial project.
Update: Just to throw some gasoline in the open fire you started, here are two interesting articles from people on the SQL camp. :-)
I Can't Wait for NoSQL to Die (original article is gone, here's a copy)

Update: Well here is an interesting article about NoSQL
Making Sense of NoSQL
This maybe irrelevant and of no use, but as it's javascript, you don't have to use the ternary as suggested above in the ng-click statement. You should also be able to use the lazy evaluation ("or die") syntax as well. So for your example above:
<input ng-click="{{if(profileForm.$valid) updateMyProfile()}}" name="submit" id="submit" value="Save" class="submit" type="submit">
would become:
<input ng-click="profileForm.$valid && updateMyProfile()" name="submit" id="submit" value="Save" class="submit" type="submit">
In this case, if the profile is not valid then nothing happens, otherwise, updateMyProfile() is called. Like in the link @falinsky provides above.

If you want to have see changes in the click event, i.e. Color of your UIVIew shud change whenever user clicks the UIView then make changes as below...
class ClickableUIView: UIView {
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
if let touch = touches.first {
let currentPoint = touch.locationInView(self)
// do something with your currentPoint
}
self.backgroundColor = UIColor.magentaColor()//Color when UIView is clicked.
}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
if let touch = touches.first {
let currentPoint = touch.locationInView(self)
// do something with your currentPoint
}
self.backgroundColor = UIColor.magentaColor()//Color when UIView is clicked.
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
if let touch = touches.first {
let currentPoint = touch.locationInView(self)
// do something with your currentPoint
}
self.backgroundColor = UIColor.whiteColor()//Color when UIView is not clicked.
}//class closes here
Also, call this Class from Storyboard & ViewController as:
@IBOutlet weak var panVerificationUIView:ClickableUIView!
If you've committed and pushed the changes, you can do this to get the file back
// Replace 2 with the # of commits back before the file was deleted.
git checkout HEAD~2 path/to/file

.enquiry_fld_normal{
width:278px !important;
}
.enquiry_fld_normal_select{
width:280px !important;
}
I have used the below as a background for the layout:

I am using the following test to see if strings have been urlencoded:
if(urlencode($str) != str_replace(['%','+'], ['%25','%2B'], $str))
If a string has already been urlencoded, the only characters that will changed by double encoding are % (which starts all encoded character strings) and + (which replaces spaces.) Change them back and you should have the original string.
Let me know if this works for you.
You can get the text of the selected item in any section of the picker using the same function that the pickerView does, from your custom ViewController class:
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
using the selected item
[myPickerView selectedRowInComponent:0]
so to set the text of a label in a custom cell using the currently selected value from the 2nd section of myPickerView (a property of your view controller probably)
[cell.label setText:[self pickerView:myPickerView titleForRow:[myPickerView selectedRowInComponent:1] forComponent:1]];
Just change both :1s to :2s, etc for each section
Parsing a string back to date/time value in an unknown format is inherently impossible (let's face it, what does 3/3/3
actually mean?!), all we can do is "best effort"
This solution doesn't throw an Exception
, it returns a boolean
, this is by design. Any Exception
s are used purely as a guard mechanism.
Since it's now 2018 and Java 8+ has the date/time API (and the rest have the ThreeTen backport). The solution remains basically the same, but becomes slightly more complicated, as we need to perform checks for:
This makes it look something like...
public static boolean isValidFormat(String format, String value, Locale locale) {
LocalDateTime ldt = null;
DateTimeFormatter fomatter = DateTimeFormatter.ofPattern(format, locale);
try {
ldt = LocalDateTime.parse(value, fomatter);
String result = ldt.format(fomatter);
return result.equals(value);
} catch (DateTimeParseException e) {
try {
LocalDate ld = LocalDate.parse(value, fomatter);
String result = ld.format(fomatter);
return result.equals(value);
} catch (DateTimeParseException exp) {
try {
LocalTime lt = LocalTime.parse(value, fomatter);
String result = lt.format(fomatter);
return result.equals(value);
} catch (DateTimeParseException e2) {
// Debugging purposes
//e2.printStackTrace();
}
}
}
return false;
}
This makes the following...
System.out.println("isValid - dd/MM/yyyy with 20130925 = " + isValidFormat("dd/MM/yyyy", "20130925", Locale.ENGLISH));
System.out.println("isValid - dd/MM/yyyy with 25/09/2013 = " + isValidFormat("dd/MM/yyyy", "25/09/2013", Locale.ENGLISH));
System.out.println("isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = " + isValidFormat("dd/MM/yyyy", "25/09/2013 12:13:50", Locale.ENGLISH));
System.out.println("isValid - yyyy-MM-dd with 2017-18--15 = " + isValidFormat("yyyy-MM-dd", "2017-18--15", Locale.ENGLISH));
output...
isValid - dd/MM/yyyy with 20130925 = false
isValid - dd/MM/yyyy with 25/09/2013 = true
isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = false
isValid - yyyy-MM-dd with 2017-18--15 = false
Simple try and parse the String
to the required Date
using something like SimpleDateFormat
Date date = null;
try {
SimpleDateFormat sdf = new SimpleDateFormat(format);
date = sdf.parse(value);
if (!value.equals(sdf.format(date))) {
date = null;
}
} catch (ParseException ex) {
ex.printStackTrace();
}
if (date == null) {
// Invalid date format
} else {
// Valid date format
}
You could then simply write a simple method that performed this action and returned true
when ever Date
was not null...
As a suggestion...
Updated with running example
I'm not sure what you are doing, but, the following example...
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class TestDateParser {
public static void main(String[] args) {
System.out.println("isValid - dd/MM/yyyy with 20130925 = " + isValidFormat("dd/MM/yyyy", "20130925"));
System.out.println("isValid - dd/MM/yyyy with 25/09/2013 = " + isValidFormat("dd/MM/yyyy", "25/09/2013"));
System.out.println("isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = " + isValidFormat("dd/MM/yyyy", "25/09/2013 12:13:50"));
}
public static boolean isValidFormat(String format, String value) {
Date date = null;
try {
SimpleDateFormat sdf = new SimpleDateFormat(format);
date = sdf.parse(value);
if (!value.equals(sdf.format(date))) {
date = null;
}
} catch (ParseException ex) {
ex.printStackTrace();
}
return date != null;
}
}
Outputs (something like)...
java.text.ParseException: Unparseable date: "20130925"
isValid - dd/MM/yyyy with 20130925 = false
isValid - dd/MM/yyyy with 25/09/2013 = true
isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = false
at java.text.DateFormat.parse(DateFormat.java:366)
at javaapplication373.JavaApplication373.isValidFormat(JavaApplication373.java:28)
at javaapplication373.JavaApplication373.main(JavaApplication373.java:19)
Not correct. For isValidFormat("yyyy-MM-dd", "2017-18--15"); not throw any Exception.
isValid - yyyy-MM-dd", "2017-18--15 = false
Seems to work as expected for me - the method doesn't rely on (nor does it throw) the exception alone to perform it's operation

No multi-line comments in R as of version 2.12 and unlikely to change. In most environments, you can comment blocks by highlighting and toggle-comment. In emacs, this is 'M-x ;'.
If the app minSdkVersion
which you are working is level 9, you can use:
android:foreground="?selectableItemBackground"
android:clickable="true"
Instead, starting from level 11, you use:
android:foreground="?android:attr/selectableItemBackground"
android:clickable="true"
From documentation:
clickable - Defines whether this view reacts to click events. Must be a boolean value, either "true" or "false".
foreground - Defines the drawable to draw over the content. This can be used as an overlay. The foreground drawable participates in the padding of the content if the gravity is set to fill.

In my case, Jay D is right. I have to add this before the call.
$.ajaxSetup({
async: false
});
In my previous code, I have this:
var jsonData= (function() {
var result;
$.ajax({
type:'GET',
url:'data.txt',
dataType:'json',
async:false,
success:function(data){
result = data;
}
});
return result;
})();
alert(JSON.stringify(jsonData));
It works find. Then I change to
var jsonData= (function() {
var result;
$.getJSON('data.txt', {}, function(data){
result = data;
});
return result;
})();
alert(JSON.stringify(jsonData));
The alert is undefined.
If I add those three lines, the alert shows the data again.
$.ajaxSetup({
async: false
});
var jsonData= (function() {
var result;
$.getJSON('data.txt', {}, function(data){
result = data;
});
return result;
})();
alert(JSON.stringify(jsonData));
It all depends on how big the unit of work, but I guess you're trying to treat each <product/>
nodes in succession.
For that, the simplest way would be to use XMLReader to get to each node, then use SimpleXML to access them. This way, you keep the memory usage low because you're treating one node at a time and you still leverage SimpleXML's ease of use. For instance:
$z = new XMLReader;
$z->open('data.xml');
$doc = new DOMDocument;
// move to the first <product /> node
while ($z->read() && $z->name !== 'product');
// now that we're at the right depth, hop to the next <product/> until the end of the tree
while ($z->name === 'product')
{
// either one should work
//$node = new SimpleXMLElement($z->readOuterXML());
$node = simplexml_import_dom($doc->importNode($z->expand(), true));
// now you can use $node without going insane about parsing
var_dump($node->element_1);
// go to next <product />
$z->next('product');
}
Quick overview of pros and cons of different approaches:
XMLReader only
Pros: fast, uses little memory
Cons: excessively hard to write and debug, requires lots of userland code to do anything useful. Userland code is slow and prone to error. Plus, it leaves you with more lines of code to maintain
XMLReader + SimpleXML
Pros: doesn't use much memory (only the memory needed to process one node) and SimpleXML is, as the name implies, really easy to use.
Cons: creating a SimpleXMLElement object for each node is not very fast. You really have to benchmark it to understand whether it's a problem for you. Even a modest machine would be able to process a thousand nodes per second, though.
XMLReader + DOM
Pros: uses about as much memory as SimpleXML, and XMLReader::expand() is faster than creating a new SimpleXMLElement. I wish it was possible to use simplexml_import_dom()
but it doesn't seem to work in that case
Cons: DOM is annoying to work with. It's halfway between XMLReader and SimpleXML. Not as complicated and awkward as XMLReader, but light years away from working with SimpleXML.
My advice: write a prototype with SimpleXML, see if it works for you. If performance is paramount, try DOM. Stay as far away from XMLReader as possible. Remember that the more code you write, the higher the possibility of you introducing bugs or introducing performance regressions.
For example this is my html template:
<select class="custom-select d-block w-100" id="genre" name="genre"
[(ngModel)]="film.genre"
#genreInput="ngModel"
required>
<option value="">Choose...</option>
<option *ngFor="let genre of genres;" [value]="genre.value">{{genre.name}}</option>
</select>
This is the field that binded with template from my Component:
// Genres of films like action or drama that will populate dropdown list.
genres: Genre[];
I fetch genres of films from server dynamically. In order do communicate with server I have created FilmService
This is the method which communicate server:
fetchGenres(): Observable<Genre[]> {
return this.client.get(WebUtils.RESOURCE_HOST_API + 'film' + '/genre') as Observable<Genre[]>;
}
Why this method returns Observable<Genre[]>
not something like Genre[]
?
JavaScript is async
and it does not wait for a method to return value after an expensive process. With expensive I mean a process that take a time to return value. Like fetching data from server. So you have to return reference of Observable and subscribe it.
For example in my Component :
ngOnInit() {
this.filmService.fetchGenres().subscribe(
val => this.genres = val
);
}
You can also use git diff HEAD file
to show the diff for a specific file.

I have a Samsung Galaxy and I had the same issue as you. Here's how to fix it:
In device manager on your Windows PC, even though it might say the USB drivers are installed correctly, there may exist corruption.
I went into device manager and uninstalled SAMSUNG Android USB Composite Device and made sure to check the box 'delete driver software'. Now the device will have an exclamation mark etc. I right clicked and installed the driver again (refresh copy). This finally made adb acknowledge my phone as an emulator.
As others noted, for Nexus 4, you can also try this fix.
If you want a dictionary you can import from a file by name, and also that adds entries that are nicely sorted, and contains strings you want to preserve, you can try this:
data = {'A': 'a', 'B': 'b', }
with open('file.py','w') as file:
file.write("dictionary_name = { \n")
for k in sorted (data.keys()):
file.write("'%s':'%s', \n" % (k, data[k]))
file.write("}")
Then to import:
from file import dictionary_name
I think you want to open
the ZipFile, which returns a file-like object, rather than read

Here is another way using list comprehension (some people might find it debatable). It is very approachable for simple tests, e.g. comparisons on object attributes (which I need a lot):
el = [x for x in mylist if x.attr == "foo"][0]
Of course this assumes the existence (and, actually, uniqueness) of a suitable element in the list.
private void deleteFileOrFolder(File file){
try {
for (File f : file.listFiles()) {
f.delete();
deleteFileOrFolder(f);
}
} catch (Exception e) {
e.printStackTrace(System.err);
}
}
I'm assuming mysql_fetch_array() perfroms a loop, so I'm interested in if using a while() in conjunction with it, if it saves a nested loop.
No. mysql_fetch_array
just returns the next row of the result and advances the internal pointer. It doesn't loop. (Internally it may or may not use some loop somewhere, but that's irrelevant.)
while ($row = mysql_fetch_array($result)) {
...
}
This does the following:
mysql_fetch_array
retrieves and returns the next row$row
true
, the contents of the loop are executed$row = mysql_fetch_array($result); foreach($row as $r) { ... }
This does the following:
mysql_fetch_array
retrieves and returns the next row$row
foreach
loops over the contents of the array and executes the contents of the loop as many times as there are items in the arrayIn both cases mysql_fetch_array
does exactly the same thing. You have only as many loops as you write. Both constructs do not do the same thing though. The second will only act on one row of the result, while the first will loop over all rows.
If you HAVE to, and you don't mind a hack, you could let serialization do the work for you.
Given these classes:
public class ParentObj
{
public string Name { get; set; }
}
public class ChildObj : ParentObj
{
public string Value { get; set; }
}
You can create a child instance from a parent instance like so:
var parent = new ParentObj() { Name = "something" };
var serialized = JsonConvert.SerializeObject(parent);
var child = JsonConvert.DeserializeObject<ChildObj>(serialized);
This assumes your objects play nice with serialization, obv.
Be aware that this is probably going to be slower than an explicit converter.
As others have pointed out, listeners have to be registered in order to read these streams. Also note that Debug.Write
will only function if the DEBUG
build flag is set, while Trace.Write
will only function if the TRACE
build flag is set.
Setting the DEBUG
and/or TRACE
flags is easily done in the project properties in Visual Studio or by supplying the following arguments to csc.exe
/define:DEBUG;TRACE
$(OBJDIR):
mkdir $@
Which also works for multiple directories, e.g..
OBJDIRS := $(sort $(dir $(OBJECTS)))
$(OBJDIRS):
mkdir $@
Adding $(OBJDIR)
as the first target works well.
Use screen: Start screen
, start your script, press Ctrl+A, D. Reattach with screen -r
.
Make a script that takes your "1" as a parameter, run nohup yourscript
:
#!/bin/bash
(time bash executeScript $1 input fileOutput $> scrOutput) &> timeUse.txt
sys.exit(myString)
doesn't mean "return this string". If you pass a string to sys.exit
, sys.exit
will consider that string to be an error message, and it will write that string to stderr
. The closest concept to a return value for an entire program is its exit status, which must be an integer.
If you want to capture output written to stderr, you can do something like
python yourscript 2> return_file
You could do something like that in your bash script
output=$((your command here) 2> &1)
This is not guaranteed to capture only the value passed to sys.exit
, though. Anything else written to stderr will also be captured, which might include logging output or stack traces.
example:
test.py
print "something"
exit('ohoh')
t.sh
va=$(python test.py 2>&1)
mkdir $va
bash t.sh
edit
Not sure why but in that case, I would write a main script and two other scripts... Mixing python and bash is pointless unless you really need to.
import script1
import script2
if __name__ == '__main__':
filename = script1.run(sys.args)
script2.run(filename)
Has anyone considered using int.Parse()
and int.TryParse()
like this
int bar = int.Parse(foo.ToString());
Even better like this
int bar;
if (!int.TryParse(foo.ToString(), out bar))
{
//Do something to correct the problem
}
It's a lot safer and less error prone
Use the New Java File classes in Java >=7.
Create the below method and import the necessary libs.
public static void copyFile( File from, File to ) throws IOException {
Files.copy( from.toPath(), to.toPath() );
}
Use the created method as below within main:
File dirFrom = new File(fileFrom);
File dirTo = new File(fileTo);
try {
copyFile(dirFrom, dirTo);
} catch (IOException ex) {
Logger.getLogger(TestJava8.class.getName()).log(Level.SEVERE, null, ex);
}
NB:- fileFrom is the file that you want to copy to a new file fileTo in a different folder.

As you have to use WITH (NOLOCK) for each table it might be annoying to write it in every FROM or JOIN clause. However it has a reason why it is called a "dirty" read. So you really should know when you do one, and not set it as default for the session scope. Why?
Forgetting a WITH (NOLOCK) might not affect your program in a very dramatic way, however doing a dirty read where you do not want one can make the difference in certain circumstances.
So use WITH (NOLOCK) if the current data selected is allowed to be incorrect, as it might be rolled back later. This is mostly used when you want to increase performance, and the requirements on your application context allow it to take the risk that inconsistent data is being displayed. However you or someone in charge has to weigh up pros and cons of the decision of using WITH (NOLOCK).
How do you return a JSON object from a Java Servlet
response.setContentType("application/json");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
//create Json Object
JsonObject json = new JsonObject();
// put some value pairs into the JSON object .
json.addProperty("Mobile", 9999988888);
json.addProperty("Name", "ManojSarnaik");
// finally output the json string
out.print(json.toString());
It is quite evident that there is only a single id
corresponding to a single username
because username
is unique.
But the actual problem lies in the query itself-
$sql = "SELECT 'id' FROM Users WHERE username='$name'";
+----+
| id |
+----+
| id |
+----+
i.e. 'id'
actually is treated as a string not as the id
attribute.
$sql = "SELECT `id` FROM Users WHERE username='$name'";
i.e. use grave accent(`) instead of single quote(').
or
$sql = "SELECT id FROM Users WHERE username='$name'";
session_start();
$name = $_GET["username"];
$sql = "SELECT `id` FROM Users WHERE username='$name'";
$result = mysql_query($sql);
$row=mysql_fetch_array($result)
$value = $row[0];
$_SESSION['myid'] = $value;
You can cast List<> to ArrayList<> if you understand what you doing. Java compiler won't block it.
But:
if (list instanceof ArrayList<Task>) {
ArrayList<Task> arraylist = (ArrayList<Task>) list;
}
ArrayList<Task> arraylist = Lists.newArrayList(list);
More flexible way is to use FileTimeFilterJS.bat
:
@echo off
::::::::::::::::::::::
set "_DIR=C:\Users\npocmaka\Downloads"
set "_DAYS=-5"
::::::::::::::::::::::
for /f "tokens=* delims=" %%# in ('FileTimeFilterJS.bat "%_DIR%" -dd %_DAYS%') do (
echo deleting "%%~f#"
echo del /q /f "%%~f#"
)
The script will allow you to use measurements like days, minutes ,seconds or hours. To choose weather to filter the files by time of creation, access or modification To list files before or after a certain date (or between two dates) To choose if to show files or dirs (or both) To be recursive or not
Your code works fine for me. It replaced the text in the file as expected and didn't append.
If you wanted to append, you set the second parameter in
new FileWriter(fnew,false);
to true;
Not with the HTML file control, no. A flash file uploader can do that for you though. You could use some client-side code to check for the PDF extension after they select, but you cannot directly control what they can select.
I hope this will be help you
import java.util.ArrayList;
public class Demo {
public static void main(String[] args) {
Object obj2 =null;
ArrayList al1 = (ArrayList) obj2;
al1 = (ArrayList) obj2;
System.out.println("List2 Value: " + al1);
}
}
obj2 Object is default null before you cast it to ArrayList. That's why print 'al1' as null.
Using the usual grouper recipe, you could do:
Python 2:
d = dict(itertools.izip_longest(*[iter(l)] * 2, fillvalue=""))
Python 3:
d = dict(itertools.zip_longest(*[iter(l)] * 2, fillvalue=""))
This is an old question, but I use the following class to do the job. It's based on Scott Dorman's blog:
public class NameValueCollectionConfigurationSection : ConfigurationSection
{
private const string COLLECTION_PROP_NAME = "";
public IEnumerable<KeyValuePair<string, string>> GetNameValueItems()
{
foreach ( string key in this.ConfigurationCollection.AllKeys )
{
NameValueConfigurationElement confElement = this.ConfigurationCollection[key];
yield return new KeyValuePair<string, string>
(confElement.Name, confElement.Value);
}
}
[ConfigurationProperty(COLLECTION_PROP_NAME, IsDefaultCollection = true)]
protected NameValueConfigurationCollection ConfCollection
{
get
{
return (NameValueConfigurationCollection) base[COLLECTION_PROP_NAME];
}
}
The usage is straightforward:
Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
NameValueCollectionConfigurationSection config =
(NameValueCollectionConfigurationSection) configuration.GetSection("MyParams");
NameValueCollection myParamsCollection = new NameValueCollection();
config.GetNameValueItems().ToList().ForEach(kvp => myParamsCollection.Add(kvp));

});
event.preventDefault();
});

Simplifying Damian's great answer,
public static T ParseXml<T>(this string value) where T : class
{
var xmlSerializer = new XmlSerializer(typeof(T));
using (var textReader = new StringReader(value))
{
return (T) xmlSerializer.Deserialize(textReader);
}
}
Can you try this,

$.ajax({

data: "password="+password,
success: function(html) {
var arr=$.parseJSON(html);
if(arr == "Successful")
{
**$("form[name='form']").submit();**
return true;
}
else
{ return false;
}
}
});
**return false;**
}
The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct
approach is executed like:
business_key
values to a temporary tableThe group by
could be executed like:
business key
in a hashtableThe first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.
Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.
Go to your desired perspective. Go to 'Window->show view' menu.
If you see logcat there, click it and you are done.
Else, click on 'other' (at the bottom), chose 'Android'->logcat.
Hope that helps :-)
Great solutions here, just one more option that taking into consideration handling of null
values:
Map<String,Object> map = new HashMap<>();
Map<String,String> stringifiedMap = map.entrySet().stream()
.filter(m -> m.getKey() != null && m.getValue() !=null)
.collect(Collectors.toMap(Map.Entry::getKey, e -> (String)e.getValue()));
You need something like this: https://github.com/axkibe/lsyncd It is a tool which combines rsync and inotify - the former is a tool that mirrors, with the correct options set, a directory to the last bit. The latter tells the kernel to notify a program of changes to a directory ot file. It says:
It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes.
But - according to Digital Ocean at https://www.digitalocean.com/community/tutorials/how-to-mirror-local-and-remote-directories-on-a-vps-with-lsyncd - it ought to be in the Ubuntu repository!
I have similar requirements, and this tool, which I have yet to try, seems suitable for the task.
That's because that's an SQL function, not PHP. You can use PDO::lastInsertId()
.
Like:
$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();
If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:
$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();
Just for fun, here some test:

I had the same problem. This what worked for me:
Here is an image so that you can get the bigger picture, I blurred my credentials of course:
I have copied your code and it runs fine.
I suspect you are simply having some problem in the actual file name of hello.txt, or you are running in a wrong directory. Consider verifying by the method suggested by @Eng.Fouad
num = list(str(100))
index = len(num)
while index > 0:
index -= 1
num[index] = int(num[index])
print(num)
It prints [1, 0, 0]
object.
Let's say you are writing a test case for a negative flow where the code being tested should raise an exception.
try{
bizMethod(badData);
fail(); // FAIL when no exception is thrown
} catch (BizException e) {
assert(e.errorCode == THE_ERROR_CODE_U_R_LOOKING_FOR)
}
Only one option doesn't mentioned in the answers. You can de-normalize your DB design. So you need two tables. One table contains proper list, one item per row, another table contains whole list in one column (coma-separated, for example).
Here it is 'traditional' DB design:
List(ListID, ListName)
Item(ItemID,ItemName)
List_Item(ListID, ItemID, SortOrder)
Here it is de-normalized table:
Lists(ListID, ListContent)
The idea here - you maintain Lists table using triggers or application code. Every time you modify List_Item content, appropriate rows in Lists get updated automatically. If you mostly read lists it could work quite fine. Pros - you can read lists in one statement. Cons - updates take more time and efforts.
You could try qemu, which is what the Android emulator uses. I believe it actually emulates the ARM hardware.
A couple of days ago I found a very nice solution of this problem. Read about it here. In two words Mike created a AsyncTaskManager that mediates ProgressDialog and AsyncTask. It's very easy to use this solution. You just need to include in your project several interfaces and several classes and in your activity write some simple code and nest your new AsyncTask from BaseTask. I also advice you to read comments because there are some useful tips.
Since every control element gets referenced with its name on the form element (see forms specs), controls with name "submit" will override the build-in submit function.
Which leads to the error mentioned in comments above:
Uncaught TypeError: Property 'submit' of object
#<HTMLFormElement>
is not a function
As in the accepted answer above the simplest solution would be to change the name of that control element.
However another solution could be to use dispatchEvent
method on form element:
$("#form_id")[0].dispatchEvent(new Event('submit'));
Took me a while to find this out but if you a number stored in a variable, say x and you want to select it, use
document.querySelector('a[data-a= + CSS.escape(x) + ']').
This is due to some attribute naming specifications that I'm not yet very familiar with. Hope this will help someone.
if you right click on any of the rows you can export the item or the entire data set as HAR which appears to be a JSON format.
It shouldn't be terribly difficult to script up something to transform that to a csv if you really need it in excel, but if you're already scripting you might as well just use the script to ask your questions of the data.
If anyone knows how to drive the "load page, export data" part of the process from the command line I'd be quite interested in hearing how
Sorry not sure what was going on this worked in the end:

You guys are right, but as I'm a newcomer it took me a little while to figure out all the steps to do that. Here's what worked for me:
If you want to merge the filters (eg. CSV and Excel files), use this formula:
OpenFileDialog of = new OpenFileDialog();
of.Filter = "CSV files (*.csv)|*.csv|Excel Files|*.xls;*.xlsx";
Or if you want to see XML or PDF files in one time use this:
of.Filter = @" XML or PDF |*.xml;*.pdf";
You can use cut
to access the second field:
cut -f2
Edit:
Sorry, didn't realise that SVN doesn't use tabs in its output, so that's a bit useless. You can tailor cut
to the output but it's a bit fragile - something like cut -c 10-
would work, but the exact value will depend on your setup.
Another option is something like: sed 's/.\s\+//'
Had the same issue. Obviously these .jars were included with Java <= v8.x out of the box, but are not anymore. Thus one has to separately download them and place them in the appropriate classpath as highlighted by several folks above. I understand that the new Java is modularized and thus potentially more light-weight (which is certainly a good thing, since the old setup was a monster). On the other hand this - as we can see - breaks lots of old build setups. Since the time to fix these isn't chargeable to Oracle I guess this made their decision easy...
IoC / DI to me is pushing out dependencies to the calling objects. Super simple.
The non-techy answer is being able to swap out an engine in a car right before you turn it on. If everything hooks up right (the interface), you are good.
JPA is just a specification.In market there are many vendors which implements JPA. Different types of vendors implement JPA in different way. so different types of vendors provide different functionality so choose proper vendor based on your requirements.
If you are using Hibernate or any other vendors instead of JPA than you can not easily move to hibernate to EclipseLink or OpenJPA to Hibernate.But If you using JPA than you just have to change provide in persistence XML file.So migration is easily possible in JPA.
I think you want like this, DEMO
var xmlDoc = $.parseXML( xml );
var $xml = $(xmlDoc);
var $person = $xml.find("person");
$person.each(function(){
var name = $(this).find('name').text(),
age = $(this).find('age').text();
$("#ProfileList" ).append('<li>' +name+ ' - ' +age+ '</li>');
});
I use the following code to test the empty line with or without white spaces.
if len(line.strip()) == 0 :
# do something with empty line
The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):
Mikhail,
The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.
Good luck with your implementation.
Add this to the scope - https://www.googleapis.com/auth/userinfo.profile
And after authorization is done, get the information from - https://www.googleapis.com/oauth2/v1/userinfo?alt=json
It has loads of stuff - including name, public profile url, gender, photo etc.
Based on @Chand answer. This is the implementation in Typescript. A bit safer than coercing types in JS. If you remove the type annotation should be valid JS. Also using new string functions to normalise the time.
function displayTime(millisec: number) {
const normalizeTime = (time: string): string => (time.length === 1) ? time.padStart(2, '0') : time;
let seconds: string = (millisec / 1000).toFixed(0);
let minutes: string = Math.floor(parseInt(seconds) / 60).toString();
let hours: string = '';
if (parseInt(minutes) > 59) {
hours = normalizeTime(Math.floor(parseInt(minutes) / 60).toString());
minutes = normalizeTime((parseInt(minutes) - (parseInt(hours) * 60)).toString());
}
seconds = normalizeTime(Math.floor(parseInt(seconds) % 60).toString());
if (hours !== '') {
return `${hours}:${minutes}:${seconds}`;
}
return `${minutes}:${seconds}`;
}
I was solving this algorithm and get stuck with the pairs part.
This explanation help me a lot https://betterexplained.com/articles/techniques-for-adding-the-numbers-1-to-100/
So to calculate the sum of series of numbers:
n(n+1)/2
But you need to calculate this
1 + 2 + ... + (n-1)
So in order to get this you can use
n(n+1)/2 - n
that is equal to
n(n-1)/2
You want to convert html (a byte-like object) into a string using .decode
, e.g. html = response.read().decode('utf-8')
.
UPDATE
"Run as Aministrator" is just a command, enabling the program to continue some operations that require the Administrator privileges, without displaying the UAC alerts.
Even if your user is a member of administrators group, some applications like yours need the Administrator privileges to continue running, because the application is considered not safe, if it is doing some special operation, like editing a system file or something else. This is the reason why Windows needs the Administrator privilege to execute the application and it notifies you with a UAC alert. Not all applications need an Amnistrator account to run, and some applications, like yours, need the Administrator privileges.
If you execute the application with 'run as administrator' command, you are notifying the system that your application is safe and doing something that requires the administrator privileges, with your confirm.
If you want to avoid this, just disable the UAC on Control Panel.
If you want to go further, read the question Difference between "Run as Administrator" and Windows 7 Administrators Group on Microsoft forum or this SuperUser question.
This command works perfectly. I have 8GB ram in my laptop, So I set size=8192. It is all about ram and also you need set file name. I run npm run build command that's why I used build.js.

Thanks HansUp for your answer, it is very helpful and it works!
I found three patterns working in Access, yours is the best, because it works in all cases.
INNER JOIN, your variant. I will call it "closed set pattern". It is possible to join more than two tables to the same table with good performance only with this pattern.
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM
((class
INNER JOIN person AS cr
ON class.C_P_ClassRep=cr.P_Nr
)
INNER JOIN person AS cr2
ON class.C_P_ClassRep2nd=cr2.P_Nr
)
;
INNER JOIN "chained-set pattern"
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM person AS cr
INNER JOIN ( class
INNER JOIN ( person AS cr2
) ON class.C_P_ClassRep2nd=cr2.P_Nr
) ON class.C_P_ClassRep=cr.P_Nr
;
CROSS JOIN with WHERE
SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
FROM class, person AS cr, person AS cr2
WHERE class.C_P_ClassRep=cr.P_Nr AND class.C_P_ClassRep2nd=cr2.P_Nr
;
The cleanest way is to test for it's existence, drop it if it exists, and then recreate it. You can't embed a "create proc" statement inside an IF statement. This should do nicely:
IF OBJECT_ID('MySproc', 'P') IS NOT NULL
DROP PROC MySproc
GO
CREATE PROC MySproc
AS
BEGIN
...
END
setTimeout would not hold and resume on your own thread however Thread.sleep does. There is no actual equal in Javascript

Note that is should matter but this is running on Mac OS X Snow Leopard and Oracle 11g.
Strings are always modelled as immutable (atleast in heigher level languages python/java/javascript/Scala/Objective-C).
So any string operations like concatenation, replacements always returns a new string which contains intended value, whereas the original string will still be same.
At each point in these instructions, check to see if the problem is fixed. If so, great! Otherwise, continue.
#1045 - Access denied for user 'root'@'localhost' (using password: NO)
C:\wamp\apps\phpmyadmin3.5.1\config.inc.php

This is convoluted, I know, but that's what worked for me. Some posts may say you need a password in the config file, but you don't. Mine is still ""
Hope this helps.
In addition to the other suggestions - you can also wrap the flag in a control class and make a final instance of it in your parent class:
public class Test {
class Control {
public volatile boolean flag = false;
}
final Control control = new Control();
class T1 implements Runnable {
@Override
public void run() {
while ( !control.flag ) {
}
}
}
class T2 implements Runnable {
@Override
public void run() {
while ( !control.flag ) {
}
}
}
private void test() {
T1 main = new T1();
T2 help = new T2();
new Thread(main).start();
new Thread(help).start();
}
public static void main(String[] args) throws InterruptedException {
try {
Test test = new Test();
test.test();
} catch (Exception e) {
e.printStackTrace();
}
}
}

pointer-events: none;
Is a CSS property that makes events "pass through" the element to which it is applied and makes the event occur on the element "below".
See for details: https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events
It is not supported up to IE 11; all other vendors support it since quite some time (global support was ~92% in 12/'16): http://caniuse.com/#feat=pointer-events (thanks to @s4y for providing the link in the comments).
It's not clear to me what you want, but I'll mention that the Date class also has a compareTo method, which can be used to determine with one call if two Date objects are equal or (if they aren't equal) which occurs sooner. This allows you to do something like:
switch (today.compareTo(questionDate)) {
case -1: System.out.println("today is sooner than questionDate"); break;
case 0: System.out.println("today and questionDate are equal"); break;
case 1: System.out.println("today is later than questionDate"); break;
default: System.out.println("Invalid results from date comparison"); break;
}
It should be noted that the API docs don't guarantee the results to be -1, 0, and 1, so you may want to use if-elses rather than a switch in any production code. Also, if the second date is null, you'll get a NullPointerException, so wrapping your code in a try-catch may be useful.

I experienced this problem today, but unfortunately none of the suggestions here helped. The only problem was that I didn't see ANY errors.. I literally had to do an strace -p <process_id>
on the Apache thread to spot the headers being written and Apache crashing on the next line; Somewhere in my PHP code I was setting a header with over 12KB of data.
The lesson here is that in some cases, Apache crashing with a HTTP error 500 - Premature end of script
-failure can be the result of having too long or overflowing HTTP headers.
Debug your headers for length if you have this same problems because most (if not all) web servers have HTTP header limits.
PS: This reply has some info on header sizes.
If you have access to a console in the context you are investigating, you can determine which version you are running by printing the value of the global constant RUBY_VERSION
.
Although a bit late, I've come across this question while searching the solution for the same problem, so I hope it can be of any help...
Found myself in the same darkness than you. Just found this article, which explains some new hints introduced in NetBeans 7.4, including this one:
https://blogs.oracle.com/netbeansphp/entry/improve_your_code_with_new
The reason why it has been added is because superglobals usually are filled with user input, which shouldn't ever be blindly trusted. Instead, some kind of filtering should be done, and that's what the hint suggests. Filter the superglobal value in case it has some poisoned content.
For instance, where I had:
$_SERVER['SERVER_NAME']
I've put instead:
filter_input(INPUT_SERVER, 'SERVER_NAME', FILTER_SANITIZE_STRING)
You have the filter_input and filters doc here:
The error shows that com.bd.service.ArticleService
is not a registered bean. Add the packages in which you have beans that will be autowired in your application context:
<context:component-scan base-package="com.bd.service"/>
<context:component-scan base-package="com.bd.controleur"/>
Alternatively, if you want to include all subpackages in com.bd
:
<context:component-scan base-package="com.bd">
<context:include-filter type="aspectj" expression="com.bd.*" />
</context:component-scan>
As a side note, if you're using Spring 3.1 or later, you can take advantage of the @ComponentScan
annotation, so that you don't have to use any xml configuration regarding component-scan. Use it in conjunction with @Configuration
.
@Controller
@RequestMapping("/Article/GererArticle")
@Configuration
@ComponentScan("com.bd.service") // No need to include component-scan in xml
public class ArticleControleur {
@Autowired
ArticleService articleService;
...
}
You might find this Spring in depth section on Autowiring useful.
NumberFormat currency = NumberFormat.getCurrencyInstance();
String myCurrency = currency.format(123.5);
System.out.println(myCurrency);
output:
$123.50
If you want to change the currency,
NumberFormat currency = NumberFormat.getCurrencyInstance(Locale.CHINA);
String myCurrency = currency.format(123.5);
System.out.println(myCurrency);
output:

Consider the following situation:
You are in the middle of a large, empty room, when a zombie suddenly attacks you.
You have no weapon.
Luckily, a fellow living human is standing in the doorway of the room.
"Quick!" you shout at him. "Throw me something I can hit the zombie with!"
Now consider:
You didn't specify (nor do you care) exactly what your friend will choose to toss;
...But it doesn't matter, as long as:
It's something that can be tossed (He can't toss you the sofa)
It's something that you can grab hold of (Let's hope he didn't toss a shuriken)
It's something you can use to bash the zombie's brains out (That rules out pillows and such)
It doesn't matter whether you get a baseball bat or a hammer -
as long as it implements your three conditions, you're good.
To sum it up:
When you write an interface, you're basically saying: "I need something that..."
For the first rule,
Click "greater than", then in the value option box, click on the cell criteria you want it to be less than, than use the format drop-down to select your color.
For the second,
Click "less than", then in the value option box, type "=.9*" and then click the cell criteria, then use the formatting just like step 1.
For the third,
Same as the second, except your formula is =".8*" rather than .9.

Instead of modifying the height and width attributes of the image, try modifying the CSS height and width.
myimg = document.getElementById('myimg');
myimg.style.height = "50px";
myimg.style.width = "50px";
One common "gotcha" is that the height and width styles are strings that include a unit, like "px" in the example above.
Edit - I think that setting the height and width directly instead of using style.height and style.width should work. It would also have the advantage of already having the original dimensions. Can you post a bit of your code? Are you sure you're in standards mode instead of quirks mode?
This should work:
myimg = document.getElementById('myimg');
myimg.height = myimg.height * 2;
myimg.width = myimg.width * 2;
Below is a python function that uses module htmlentitydefs
. It is not perfect. The version of htmlentitydefs

if decimal_digits: return unichr(int(decimal_digits, 10))
name = match.group(3) # name is 'lt' when '<' was matched.
if name:
decoding = (htmlentitydefs.name2codepoint.get(name)

Complete all the installation steps and restart Eclipse. You'll see a bunch of servers when you try to add a server runtime environment.
There is a plugin that adds a menu entitled TextFX
. This menu, which houses a dizzying array of quick text editing options, gives a person the ability to make quick coding changes. In this menu, you can find selections such as Drop Quotes, Delete Blank Lines as well as Unwrap and Rewrap Text
Do the following:
TextFX > TextFX Edit > Delete Blank Lines
TextFX > TextFX Edit > Delete Surplus Blank Lines
You need to reference both Microsoft.ReportViewer.WebForms and Microsoft.ReportViewer.Common and set the CopyLocal property to true. This will result in the dll's being copied to our bin directory (both are necessary).
To add one year to todays date use the following:

Since it sounds like you already know what format the byte[] array is in (e.g. RGB, ARGB, BGR etc.) you might be able to use BufferedImage.setRGB(...), or a combination of BufferedImage.getRaster() and WritableRaster.setPixels(...) or WritableRaster.setSamples(...). Unforunately both of these methods require you transform your byte[] into one of int[], float[] or double[] depending on the image format.
Jelly Bean adds support for this with the ActivityOptions.makeCustomAnimation() method. Of course, since it's only on Jelly Bean, it's pretty much worthless for practical purposes.
You need to check the folder permissions on your server and check that the account that you are using to run your application has access to that folder.
You could use limitTo
filter with -1

{{friend.name}}
</div>
char *charPtr = "test string";
cout << charPtr << endl;
string str = charPtr;
cout << str << endl;

Just create .htaccess file at root and add these lines to it
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(.*)$ public/$1 [L]
</IfModule>
That's it!
The above code works on the root public_html folder. Having said that your core laravel file should be inside the public_html folder, if your directory looks like public_html/laravelapp/public and if you put the above code inside laravelapp it won't work. Therefore you must copy all your core files into public_html and put the .htaccess file there .
If you want to keep the code in a subdirectory then you can create a subdomain then this code will work for that also.
You can use At
from pydash:
from pydash import at
dict = {'a': 1, 'b': 2, 'c': 3}
list = at(dict, 'a', 'b')
list == [1, 2]
My solution to this (which hasn't caused any performance issues):
Array.prototype.remove = function(from, to) { var rest = this.slice((to || from) + 1 || this.length); this.length = from < 0 ? this.length + from : from; return this.push.apply(this, rest); };
I'm using it in all of my projects and credits go to John Resig John Resig's Site
$scope.items.forEach(function(element, index, array){ if(element.name === 'ted'){ $scope.items.remove(index); } });
At the end the $digest will be fired in angularjs and my UI is updated immediately without any recognizable lag.
If you want blanks and NULLS to be displayed as other text, such as "Uncategorized" you can simply say...
SELECT ISNULL(NULLIF([PropertyValue], ''), 'Uncategorized') FROM UserProfile
The above answers the main question very well. This answer is an extension of that and is of value to readers.
In addition to the answer by ProGM, in case you see characters in boxes like NUL or ACK and want to get rid of them, those are ASCII control characters (0 to 31), you can find them with the following expression and remove them:
[\x00-\x1F]+
In order to remove all non-ASCII AND ASCII control characters, you should remove all characters matching this regex:
[^\x1F-\x7F]+
Another approach would be to create an embedded server to "host" your servlet, allowing you to write calls against it with libraries meant to make calls to actual servers (the usefulness of this approach somewhat depends on how easily you can make "legitimate" programatic calls to the server - I was testing a JMS (Java Messaging Service) access point, for which clients abound).
There are a couple of different routes you can go - the usual two are tomcat and jetty.
Warning: something to be mindful of when choosing the server to embed is the version of servlet-api you are using (the library which provides classes like HttpServletRequest). If you are using 2.5, I found Jetty 6.x to work well (which is the example I'll give below). If you're using servlet-api 3.0, the tomcat-7 embedded stuff seems to be a good option, however I had to abandon my attempt to use it, as the application I was testing used servlet-api 2.5. Trying to mix the two will result in NoSuchMethod and other such exceptions when attempting to configure or start the server.
You can set up such a server like this (Jetty 6.1.26, servlet-api 2.5):
public void startServer(int port, Servlet yourServletInstance){
Server server = new Server(port);
Context root = new Context(server, "/", Context.SESSIONS);
root.addServlet(new ServletHolder(yourServletInstance), "/servlet/context/path");
//If you need the servlet context for anything, such as spring wiring, you coudl get it like this
//ServletContext servletContext = root.getServletContext();
server.start();
}
And of course you can never call the two functions at the same time. Not any one in the world except you are working on two processors simultaneously.
The best way is to call a JavaScript parent function and in that, specify all the sequence of function you want to call. For example,
function ShowDiv1() {
document.getElementById("ReportDiv").style.display = 'block';
return false;
}
function validateView()
{
if (document.getElementById("ctl00_ContentPlaceHolder1_DLCategory").selectedIndex == 0) {
document.getElementById("ctl00_ContentPlaceHolder1_ErrorMsg").innerHTML = "Please Select Your Category";
document.getElementById("ctl00_ContentPlaceHolder1_DLCategory").focus();
return false;
}
if (document.getElementById("ctl00_ContentPlaceHolder1_DLEmpName").selectedIndex == 0) {
document.getElementById("ctl00_ContentPlaceHolder1_ErrorMsg").innerHTML = "Please Select Your Employee Name";
document.getElementById("ctl00_ContentPlaceHolder1_DLEmpName").focus();
return false;
}
ShowDiv1();
return true;
}
302 is temporary redirect, which is generated by the server whereas 307 is internal redirect response generated by the browser. Internal redirect means that redirect is done automatically by browser internally, basically the browser alters the entered url from http to https in get request by itself before making the request so request for unsecured connection is never made to the internet. Whether browser will alter the url to https or not depends upon the hsts preload list that comes preinstalled with the browser. You can also add any site which support https to the list by entering the domain in the hsts preload list of your own browser which is at chrome://net-internals/#hsts.One more thing website domains can be added by their owners to preload list by filling up the form at https://hstspreload.org/ so that it comes preinstalled in browsers for every user even though I mention you can do particularly for yourself also.
Let me explain with an example:
I made a get request to http://www.pentesteracademy.com which supports only https and I don't have that domain in my hsts preload list on my browser as site owner has not registered for it to come with preinstalled hsts preload list.
GET request for unsecure version of the site is redirected to secure version(see http header named location for that in response in above image).
Now I add the site to my own browser preload list by adding its domain in Add hsts domain form at chrome://net-internals/#hsts, which modifies my personal preload list on my chrome browser.Be sure to select include subdomains for STS option there.
Let's see the request and response for the same website now after adding it to hsts preload list.
you can see the internal redirect 307 there in response headers, actually this response is generated by your browser not by server.
Also HSTS preload list can help prevent users reach the unsecure version of site as 302 redirect are prone to mitm attacks.
Hope I somewhat helped you understand more about redirects.
If you're using MySQL Workbench, the mysql.server stop/restart/start

The reason #2 fails is because sys.modules['module']
does not exist (the import routine has its own scope, and cannot see the module
local name), and there's no module
module or package on-disk. Note that you can separate multiple imported names by commas.

Boost contains cstdint.hpp header file with the types you are looking for: http://www.boost.org/doc/libs/1_36_0/boost/cstdint.hpp
If you are working with a private token instead (like Gitlab API), you should replace:
$authorization = "Authorization: Bearer 080042cad6356ad5dc0a720c18b53b8e53d4c274"
with:
$authorization = "PRIVATE-TOKEN 080042cad6356ad5dc0a720c18b53b8e53d4c274";

The coming version of RStudio (1.2), already available as a preview, will include a feature to detect missing packages in library()
and require()
calls, and prompt the user to install them:
Detect missing R packages
Many R scripts open with calls to
library()
andrequire()
to load the packages they need in order to execute. If you open an R script that references packages that you don’t have installed, RStudio will now offer to install all the needed packages in a single click. No more typinginstall.packages()
repeatedly until the errors go away!
https://blog.rstudio.com/2018/11/19/rstudio-1-2-preview-the-little-things/
This seems to address the original concern of OP particularly well:
Many of them are novice/intermediate R users and don't realize that they have to install packages they don't already have.
This error seems to occur mostly if there is a space before or after your secret key
In my case, after a long search I found that PyCharm in your Django settings (Settings > Languages & Frameworks > Django) had the configuration file field undefined. You should make this field point to your project's settings file. Then, you must open the Run / Debug settings and remove the environment variable DJANGO_SETTINGS_MODULE = existing path.
This happens because the Django plugin in PyCharm forces the configuration of the framework. So there is no point in configuring any os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myapp.settings')
Your container will exit as the command you gave it will end. Use the following options to keep it live:
-i
Keep STDIN open even if not attached.-t
Allocate a pseudo-TTY.So your new run
command is:
docker run -it -d shykes/pybuilder bin/bash
If you would like to attach to an already running container:
docker exec -it CONTAINER_ID /bin/bash
In these examples /bin/bash
is used as the command.
I'm not sure if you're going to get any huge gains for reasons Jon Skeet pointed out. However, you could try and benchmark the TypeConvert.ConvertTo method and see how it compares to using your current method.
ImageConverter converter = new ImageConverter();

Some optimizing compilers will be able to do better loop unrolling with a for loop, but odds are that if you're doing something that can be unrolled, a compiler smart enough to unroll it is probably also smart enough to interpret the loop condition of your while loop as something it can unroll as well.

Than you can call this function where you want to get the value..

You want to iterate through the list, sum all the numbers, and then divide the sum by the number of elements in the list. You can use a for loop to accomplish this.
average = 0
sum = 0
for n in numbers:
sum = sum + n
average = sum / len(numbers)
The for loop looks at each element in the list, and then adds it to the current sum. You then divide by the length of the list (or the number of elements in the list) to find the average.
I would recommend googling a python reference to find out how to use common programming concepts like loops and conditionals so that you feel comfortable when starting out. There are lots of great resources online that you could look up.
Good luck!
you can apply two commands
git diff --patch > mypatch.patch // to generate the patch
git apply mypatch.patch // to apply the patch
You can use the in place option -i
of sed
for Linux and Unix:
sed -i 's/[ \t]*$//' "$1"
Be aware the expression will delete trailing t
's on OSX (you can use gsed
to avoid this problem). It may delete them on BSD too.
If you don't have gsed, here is the correct (but hard-to-read) sed syntax on OSX:
sed -i '' -E 's/[ '$'\t'']+$//' "$1"
Three single-quoted strings ultimately become concatenated into a single argument/expression. There is no concatenation operator in bash, you just place strings one after the other with no space in between.
The $'\t'
resolves as a literal tab-character in bash (using ANSI-C quoting), so the tab is correctly concatenated into the expression.
On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE
, can be tampered with so always use server side validation.
<form method="post" enctype="multipart/form-data" action="upload.php">
<input type="file" name="file" id="file" />
<input type="submit" name="submit" value="Submit" />
</form>
<script>
document.forms[0].addEventListener('submit', function( evt ) {
var file = document.getElementById('file').files[0];
if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
//Submit form
} else {
//Prevent default and display error
evt.preventDefault();
}
}, false);
</script>
On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize
. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE
has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.
On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES
array to find out the upload size. (Docs on the contents of $_FILES
can be found below the MAX_FILE_SIZE
docs)
upload.php
<?php
if(isset($_FILES['file'])) {
if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
// File too big
} else {
// File within size restrictions
}
}
Just one line will be OK.

Using GNU sed
:
sed "/cdef/aline1\nline2\nline3\nline4" input.txt
If you started with:
abcd
accd
cdef
line
web
this would produce:
abcd
accd
cdef
line1
line2
line3
line4
line
web
If you want to save the changes to the file in-place, say:
sed -i "/cdef/aline1\nline2\nline3\nline4" input.txt
Just improved phihag's code because it runs into a infinite loop if file not exists.
<?php
$filename = "so-csv.csv";
echo "<html><body><table>\n\n";
if (file_exists($filename)) {
$f = fopen($filename, "r");
while (($line = fgetcsv($f)) !== false) {
echo "<tr>";
foreach ($line as $cell) {
echo "<td>" . htmlspecialchars($cell) . "</td>";
}
echo "</tr>\n";
}
fclose($f);
}
else{ echo "<tr><td>No file exists ! </td></tr>" ;}
echo "\n</table></body></html>";

Your problem seems to be a missing space between your two classes in the CSS:
.area1.item
{
color:red;
}
Should be
.area1 .item
{
color:red;
}
Follow the next steps:
I had the same problem as you mentioned here above and my code was doing great all day yesterday.
I kept on programming this morning and when I opened my application (my file with an Auto_Open sub), I got the Run-time error '13' Type mismatch, I went on the web to find answers, I tried a lot of things, modifications and at one point I remembered that I read somewhere about "Ghost" data that stays in a cell even if we don't see it.
My code do only data transfer from one file I opened previously to another and Sum it. My code stopped at the third SheetTab (So it went right for the 2 previous SheetTab where the same code went without stopping) with the Type mismatch message. And it does that every time at the same SheetTab when I restart my code.
So I selected the cell where it stopped, manually entered 0,00 (Because the Type mismatch comes from a Summation variables declared in a DIM as Double) and copied that cell in all the subsequent cells where the same problem occurred. It solved the problem. Never had the message again. Nothing to do with my code but the "Ghost" or data from the past. It is like when you want to use the Control+End and Excel takes you where you had data once and deleted it. Had to "Save" and close the file when you wanted to use the Control+End to make sure Excel pointed you to the right cell.
In our MVC application we generate for long param
using System.Security.Cryptography;
using System.Text;
...
public static string getMD5(long id)
{
// convert
string result = (id ^ long.MaxValue).ToString("X") + "-ANY-TEXT";
using (MD5 md5Hash = MD5.Create())
{
// Convert the input string to a byte array and compute the hash.
byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(result));
// Create a new Stringbuilder to collect the bytes and create a string.
StringBuilder sBuilder = new StringBuilder();
for (int i = 0; i < data.Length; i++)
sBuilder.Append(data[i].ToString("x2"));
// Return the hexadecimal string.
result = sBuilder.ToString().ToUpper();
}
return result;
}
and same in Android application (thenk helps Andranik)
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
...
public String getIdHash(long id){
String hash = null;
long intId = id ^ Long.MAX_VALUE;
String md5 = String.format("%X-ANY-TEXT", intId);
try {
MessageDigest md = java.security.MessageDigest.getInstance("MD5");
byte[] arr = md.digest(md5.getBytes());
StringBuffer sb = new StringBuffer();
for (int i = 0; i < arr.length; ++i)
sb.append(Integer.toHexString((arr[i] & 0xFF) | 0x100).substring(1,3));
hash = sb.toString();
} catch (NoSuchAlgorithmException e) {
Log.e("MD5", e.getMessage());
}
return hash.toUpperCase();
}
a.update(b)
Will add keys and values from b to a, overwriting if there's already a value for a key.
I believe java gleans this from the environment variables in which it was launched, so you'll need to make sure your LANG and LC_* environment variables are set appropriately.
The locale manpage has full info on said environment variables.
I think @ben-rollert's solution is a good solution.
You just have to be careful if you want to use this solution in a function inside a new package.
When developping packages, it's recommended to use the syntaxe packagename::function_name()
(see http://kbroman.org/pkg_primer/pages/depends.html).
In this case, you have to use the version of as.Date()
defined by the zoo
library.
Here is an example :
> devtools::session_info()
Session info ----------------------------------------------------------------------------------------------------------------------------------------------------
setting value
version R version 3.3.1 (2016-06-21)
system x86_64, linux-gnu
ui RStudio (1.0.35)
language (EN)
collate C
tz <NA>
date 2016-11-09
Packages --------------------------------------------------------------------------------------------------------------------------------------------------------
package * version date source
devtools 1.12.0 2016-06-24 CRAN (R 3.3.1)
digest 0.6.10 2016-08-02 CRAN (R 3.2.3)
memoise 1.0.0 2016-01-29 CRAN (R 3.2.3)
withr 1.0.2 2016-06-20 CRAN (R 3.2.3)
> as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))
Error in as.Date.default(zoo::as.yearmon("1989-10", "%Y-%m")) :
do not know how to convert 'zoo::as.yearmon("1989-10", "%Y-%m")' to class “Date”
> zoo::as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))
[1] "1989-10-01"
So if you're developping a package, the good practice is to use :
zoo::as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))
Check to make sure that you don't have a specific framework search path specified. if you go to the info on the target and just remove the framework search path entries it should use the defaults for your specified deployment version.
Move the -h and specify that mydir is a directory
attrib /S /D /L -H mydir\*.*
No need to use a macro. Supposing your first string is in A1.
=RIGHT(A1, 4)
Drag this down and you will get your four last characters.
Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()
=RIGHT(TRIMSPACES(A1), 4)
Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:
=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))
@echo off
set source="C:\test case"
set target="C:\Users\Alexander\Desktop\random folder"
FOR /F "delims=" %%I IN ('DIR %source%\*.* /A:-D /O:-D /B') DO COPY %source%\"%%I" %target% & echo %%I & GOTO :END
:END
TIMEOUT 4
My attempt to copy the newest file from a folder
just set your source and target folders and it should work
This one ignores folders, concern itself only with files
Recommed that you choose filetype in the DIR path changing *.*
to *.zip
for example
TIMEOUT wont work on winXP I think
If you are on Linux:
file_put_contents('your_log_file', 'your_content');
or
error_log ('your_content', 3, 'your_log_file');
and then in console
tail -f your_log_file
This will show continuously the last line put in the file.
Sounds like you're approaching your problem the wrong way to me.
Rewrite your code to use a tuple or write a class to store all of the data.
I needed a list with all months between 2 dates for statistics. The 2 dates are the start and enddate from a subscription. So the list shows all months and the amount of subscriptions per month.
MYSQL
CREATE PROCEDURE `get_amount_subscription_per_month`()
BEGIN
-- Select the ultimate start and enddate from subscribers
select @startdate := min(DATE_FORMAT(a.startdate, "%Y-%m-01")),
@enddate := max(DATE_FORMAT(a.enddate, "%Y-%m-01")) + interval 1 MONTH
from subscription a;
-- Tmp table with all months (dates), you can always format them with DATE_FORMAT)
DROP TABLE IF EXISTS tmp_months;
create temporary table tmp_months (
year_month date,
PRIMARY KEY (year_month)
);
set @tempDate=@startdate; #- interval 1 MONTH;
-- Insert every month in tmp table
WHILE @tempDate <= @enddate DO
insert into tmp_months (year_month) values (@tempDate);
set @tempDate = (date(@tempDate) + interval 1 MONTH);
END WHILE;
-- All months
select year_month from tmp_months;
-- If you want the amount of subscription per month else leave it out
select mnd.year_month, sum(subscription.amount) as subscription_amount
from tmp_months mnd
LEFT JOIN subscription ON mnd.year_month >= DATE_FORMAT(subscription.startdate, "%Y-%m-01") and mnd.year_month <= DATE_FORMAT(subscription.enddate, "%Y-%m-01")
GROUP BY mnd.year_month;
END
As Seth stated thread safe means that a method or class instance can be used by multiple threads at the same time without any problems occuring.
Consider the following method:
private int myInt = 0;
public int AddOne()
{
int tmp = myInt;
tmp = tmp + 1;
myInt = tmp;
return tmp;
}
Now thread A
and thread B
both would like to execute AddOne()
. but A
starts first and reads the value of myInt (0)
into tmp
. Now for some reason the scheduler decides to halt thread A
and defer execution to thread B
. Thread B
now also reads the value of myInt
(still 0
) into it's own variable tmp
. Thread B
finishes the entire method, so in the end myInt = 1
. And 1
is returned. Now it's Thread A
's turn again. Thread A
continues. And adds 1
to tmp
(tmp
was 0
for thread A
). And then saves this value in myInt
. myInt
is again 1
.
So in this case the method AddOne()
was called two times, but because the method was not implemented in a thread safe way the value of myInt
is not 2
, as expected, but 1
because the second thread read the variable myInt
before the first thread finished updating it.
Creating thread safe methods is very hard in non trivial cases. And there are quite a few techniques. In Java you can mark a method as synchronized, this means that only one thread can execute that method at a given time. The other threads wait in line. This makes a method thread safe, but if there is a lot of work to be done in a method, then this wastes a lot of time. Another technique is to 'mark only a small part of a method as synchronized' by creating a lock or semaphore, and locking this small part (usually called the critical section). There are even some methods that are implemented as lockless thread safe, which means that they are built in such a way that multiple threads can race through them at the same time without ever causing problems, this can be the case when a method only executes one atomic call. Atomic calls are calls that can't be interrupted and can only be done by one thread at a time.
I run the service at IPLocate.io, which you can hook into for free with one easy call:
<?php
$res = file_get_contents('https://www.iplocate.io/api/lookup/8.8.8.8');
$res = json_decode($res);
echo $res->country; // United States
echo $res->continent; // North America
echo $res->latitude; // 37.751
echo $res->longitude; // -97.822
var_dump($res);
The $res
object will contain your geolocation fields like country
, city
, etc.
Check out the docs for more information.
You can't do
LivingRoom.objects.create(user=instance)
because you have an __init__
method that does NOT take user
as argument.
You need something like
#signal function: if a user is created, add control livingroom to the user
def create_control_livingroom(sender, instance, created, **kwargs):
if created:
my_room = LivingRoom()
my_room.user = instance
Update
But, as bruno has already said it, Django's models.Model
subclass's initializer is best left alone, or should accept *args
and **kwargs
matching the model's meta fields.
So, following better principles, you should probably have something like
class LivingRoom(models.Model):
'''Living Room object'''
user = models.OneToOneField(User)
def __init__(self, *args, temp=65, **kwargs):
self.temp = temp
return super().__init__(*args, **kwargs)
Note - If you weren't using temp
as a keyword argument, e.g. LivingRoom(65)
, then you'll have to start doing that. LivingRoom(user=instance, temp=66)
or if you want the default (65), simply LivingRoom(user=instance)
would do.
var array = (new Function("return [" + str+ "];")());

var string = "0,1";
var objectstring = '{Name:"Tshirt", CatGroupName:"Clothes", Gender:"male-female"}, {Name:"Dress", CatGroupName:"Clothes", Gender:"female"}, {Name:"Belt", CatGroupName:"Leather", Gender:"child"}';
var stringArray = (new Function("return [" + string+ "];")());
var objectStringArray = (new Function("return [" + objectstring+ "];")());

I have not tried, but if you know Perl you can use the Parse-Stata-DtaReader module to convert the file for you.
The module has a command-line tool dta2csv, which can "convert Stata 8 and Stata 10 .dta files to csv"
You don't set value to default in a table. You should clear the option "Default value or Binding" first.
