Using task scheduler, schedule a run of CMDKEY running under SYSTEM with the appropriate arguments of /add: /user: and /pass:
No need to install anything.
you can simply write:
for item,i in zip(your_list, range(len(your_list)):
if type(item) == list:
print(f"{item} at index {i} is a list")
UPDATE totals
SET total = total + 1
WHERE name = 'bill';
If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:
UPDATE totals
SET total = total + 1
WHERE name = 'bill'
AND total = 203;
Well I would do it like this instead:
TimeSpan diff = expiryDate - DateTime.Today;
if (diff.Days > 30)
matchFound = true;
Compare only responds with an integer indicating weather the first is earlier, same or later...
The presence of the logout button depends on whether you are required to login or not, in the first place. This is tweakable in PHPMyAdmin config files.
Yet, I don't think that would change anything concerning your error message. You would need to fix the configuration for the message to go away.
Edit: this is the kind of solution you should be searching for. And here are plenty of others for you to explore ^^
Wait!
There is a way to retrieve the password by using Brute-Force attack, have a look at the following tool from codeproject Retrieve SQL Server Password
To Retrieve the password of SQL Server user,run the following query in SQL Query Analyzer
"Select Password from SysxLogins Where Name = 'XXXX'" Where XXXX is the user
name for which you want to retrieve password.Copy the password field (Hashed Code) and
paste here (in Hashed code Field) and click on start button to retrieve
I checked the tool on SQLServer 2000 and it's working fine.
For deploying the war file over tomcat, Follow the below steps :
you will get one folder inside E:\Tomcat_Installation\webapps**put**
In this way you can deploy your war file in Apache Tomcat.
I figured out Leafpad to be an adequate and simple text-editor to view and save/convert in certain character sets - at least in the linux-world.
I used this to save the Latin-15 to UTF-8 and it worked.
From ?read.table
: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.
So, perhaps your data file isn't clean. Being more specific will help the data import:
d = read.table("foobar.txt",
sep="\t",
col.names=c("id", "name"),
fill=FALSE,
strip.white=TRUE)
will specify exact columns and fill=FALSE
will force a two column data frame.
You can try this code for checking which date value is the highest from two dates with a format MM/DD/YYYY:
function d_check() {
var dl_sdt=document.getElementIdBy("date_input_Id1").value; //date one
var dl_endt=document.getElementIdBy("date_input_Id2").value; //date two
if((dl_sdt.substr(6,4)) > (dl_endt.substr(6,4))) {
alert("first date is greater");
return false;
}
else if((((dl_sdt.substr(0,2)) > (dl_endt.
substr(0,2)))&&(frdt(dl_sdt.substr(3,2)) > (dl_endt.substr(3,2))))||
(((dl_sdt.substr(0,2)) > (dl_endt.substr(0,2)))&&
((dl_sdt.substr(3,2)) < (dl_endt.substr(3,2))))||
(((dl_sdt.substr(0,2)) == (dl_endt.substr(0,2)))&&((dl_sdt.substr(3,2)) >
(dl_endt.substr(3,2))))) {
alert("first date is greater");
return false;
}
alert("second date is digher");
return true;
}
/*for checking this....create a form and give id's to two date inputs.The date format should be mm/dd/yyyy or mm-dd-yyyy or mm:dd:yyyy or mm.dd.yyyy like this. */
If you are running the command from a POSIX-compliant shell, like bash
, you can set the environment variable like this:
PYTHONPATH="/path/to" python somescript.py somecommand
If it's all on one line, the PYTHONPATH environment value applies only to that one command.
$ echo $PYTHONPATH
$ python -c 'import sys;print("/tmp/pydir" in sys.path)'
False
$ PYTHONPATH=/tmp/pydir python -c 'import sys;print("/tmp/pydir" in sys.path)'
True
$ echo $PYTHONPATH
via command line we in centOs we can do this
httpd -l
you can do it better with two datagridview, you add the same datasource , hide the headers of the second, set the height of the second = to the height of the rows of the first, turn off all resizable atributes of the second, synchronize the scrollbars of both, only horizontal, put the second on the botton of the first etc.
take a look:
dgv3.ColumnHeadersVisible = false;
dgv3.Height = dgv1.Rows[0].Height;
dgv3.Location = new Point(Xdgvx, this.dgv1.Height - dgv3.Height - SystemInformation.HorizontalScrollBarHeight);
dgv3.Width = dgv1.Width;
private void dgv1_Scroll(object sender, ScrollEventArgs e)
{
if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll)
{
dgv3.HorizontalScrollingOffset = e.NewValue;
}
}
I recommend using Interweave created by milesj. Its a phenomenal library that makes use of a number if ingenious techniques to parse and safely insert HTML into the DOM.
Interweave is a react library to safely render HTML, filter attributes, autowrap text with matchers, render emoji characters, and much more.
Usage Example:
import React from 'react';
import { Markup } from 'interweave';
const articleContent = "<p><b>Lorem ipsum dolor laboriosam.</b> </p><p>Facere debitis impedit doloremque eveniet eligendi reiciendis <u>ratione obcaecati repellendus</u> culpa? Blanditiis enim cum tenetur non rem, atque, earum quis, reprehenderit accusantium iure quas beatae.</p><p>Lorem ipsum dolor sit amet <a href='#testLink'>this is a link, click me</a> Sunt ducimus corrupti? Eveniet velit numquam deleniti, delectus <ol><li>reiciendis ratione obcaecati</li><li>repellendus culpa? Blanditiis enim</li><li>cum tenetur non rem, atque, earum quis,</li></ol>reprehenderit accusantium iure quas beatae.</p>"
<Markup content={articleContent} /> // this will take the articleContent string and convert it to HTML markup. See: https://milesj.gitbook.io/interweave
//to install package using npm, execute the command
npm install interweave
You can simply go to Menu > All Programs > Visual Studio 2013. Select the folder link "Visual Studio Tools". This will open the folder. There is bunch of shortcuts for command prompt which you can use. They worked perfectly for me.
I think the trick here might be there are different versions for different processors, hence they put them all together.
Use this Way in this circle image is also working + you have preloader also for network image:
new ClipRRect(
borderRadius: new BorderRadius.circular(30.0),
child: FadeInImage.assetNetwork(
placeholder:'asset/loader.gif',
image: 'Your Image Path',
),
)
gcc objectfiles -o program -Wl,-Bstatic -ls1 -ls2 -Wl,-Bdynamic -ld1 -ld2
you can also use: -static-libgcc -static-libstdc++
flags for gcc libraries
keep in mind that if libs1.so
and libs1.a
both exists, the linker will pick libs1.so
if it's before -Wl,-Bstatic
or after -Wl,-Bdynamic
. Don't forget to pass -L/libs1-library-location/
before calling -ls1
.
For Mysql You can use this Query
UPDATE table1 a, table2 b SET a.coloumn = b.coloumn WHERE a.id= b.id
Use the setState function. So you could do
this.setState({this.state.foo.bar:123})
inside the handle event method.
Once, the state is updated, it will trigger changes, and re-render will take place.
Instead of this:
String char = name.substring(0,1); //char="a"
You should use the charAt()
method.
char c = name.charAt(0); // c='a'
int ascii = (int)c;
the way i found was to find the project compiler output (project structure > project). then find the complied folder of the module you wish to turn to a jar, compress it with zip and change the extension of the output from zip to jar.
a less-jquerish approach:
$('#mytable tr').each(function() {
if (!this.rowIndex) return; // skip first row
var customerId = this.cells[0].innerHTML;
});
this can obviously be changed to work with not-the-first cells.
In latest version of JDK, 31 is still used. https://docs.oracle.com/en/java/javase/12/docs/api/java.base/java/lang/String.html#hashCode()
The purpose of hash string is
^
in hashcode calculation document, it help unique)31 is max value can put in 8 bit (= 1 byte) register, is largest prime number can put in 1 byte register, is odd number.
Multiply 31 is <<5 then subtract itself, therefore need cheap resources.
It seems that the version "20140702" of the example link in the question was the final version, because I downloaded this file on the 12th November 2014, i.e. the version from the 2nd of July 2014 was still the latest version on 12th of November. When I try manually all the possible versions/dates between today in this date, then I always get a page with error code "404" (file not found), which indicates that no new version was released since the 12th of November.
Just in case you are like me and the Id Field of the User Entity is an Int or something else other than a string,
using Microsoft.AspNet.Identity;
int userId = User.Identity.GetUserId<int>();
will do the trick
Laravel tries to guess the name of the table, you have to specify it directly so that it does not give you that error..
Try this:
class NameModel extends Model {
public $table = 'name_exact_of_the_table';
I hope that helps!
You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.
SELECT
GROUP_CONCAT(DISTINCT (category))
FROM (
SELECT
SUBSTRING_INDEX(SUBSTRING_INDEX(tableName.categories, ' ', numbers.n), ' ', -1) category
FROM
numbers INNER JOIN tableName
ON LENGTH(tableName.categories)>=LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1
) s;
This will return distinct values like: test1,test2,test4,test3
try
raw_input('Enter your input:') # If you use Python 2
input('Enter your input:') # If you use Python 3
and if you want to have a numeric value just convert it:
try:
mode=int(raw_input('Input:'))
except ValueError:
print "Not a number"
This is spruced up from the answers just above and uses the length/number of options to conform to how many options there actually are.
Hope this helps somebody get the results they need!
function openDropdown(elementId) {
function down() {
var pos = $(this).offset(); // remember position
var len = $(this).find("option").length;
if(len > 20) {
len = 20;
}
$(this).css("position", "absolute");
$(this).css("zIndex", 9999);
$(this).offset(pos); // reset position
$(this).attr("size", len); // open dropdown
$(this).unbind("focus", down);
$(this).focus();
}
function up() {
$(this).css("position", "static");
$(this).attr("size", "1"); // close dropdown
$(this).unbind("change", up);
$(this).focus();
}
$("#" + elementId).focus(down).blur(up).focus();
}
the most effective method is to use org.apache.http.entity.mime.MultipartEntity;
see this code from the link using org.apache.http.entity.mime.MultipartEntity;
public class SimplePostRequestTest3 {
/**
* @param args
*/
public static void main(String[] args) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://localhost:8080/HTTP_TEST_APP/index.jsp");
try {
FileBody bin = new FileBody(new File("C:/ABC.txt"));
StringBody comment = new StringBody("BETHECODER HttpClient Tutorials");
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("fileup0", bin);
reqEntity.addPart("fileup1", comment);
reqEntity.addPart("ONE", new StringBody("11111111"));
reqEntity.addPart("TWO", new StringBody("222222222"));
httppost.setEntity(reqEntity);
System.out.println("Requesting : " + httppost.getRequestLine());
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpclient.execute(httppost, responseHandler);
System.out.println("responseBody : " + responseBody);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
httpclient.getConnectionManager().shutdown();
}
}
}
So i just found a solution for that: In the hover animation do this:
animation: hover 1s infinite alternate ease-in-out,splash 1;
You can also watch the output like this:
final Process p = Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug");
new Thread(new Runnable() {
public void run() {
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = null;
try {
while ((line = input.readLine()) != null)
System.out.println(line);
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
p.waitFor();
And don't forget, if you are running a windows command, you need to put cmd /c
in front of your command.
EDIT: And for bonus points, you can also use ProcessBuilder
to pass input to a program:
String[] command = new String[] {
"choice",
"/C",
"YN",
"/M",
"\"Press Y if you're cool\""
};
String inputLine = "Y";
ProcessBuilder pb = new ProcessBuilder(command);
pb.redirectErrorStream(true);
Process p = pb.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
writer.write(inputLine);
writer.newLine();
writer.close();
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
This will run the windows command choice /C YN /M "Press Y if you're cool"
and respond with a Y
. So, the output will be:
Press Y if you're cool [Y,N]?Y
As others mentioned, Justin's answer was close, but not quite right. I tested this using Visual Studio's "Paste JSON as C# Classes"
{
"foos" : [
{
"prop1":"value1",
"prop2":"value2"
},
{
"prop1":"value3",
"prop2":"value4"
}
]
}
Maybe your code is missing this line from the Microsoft example:
MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure
(SELECT C.I_WORKDATE
FROM T_COMPENSATION C
WHERE C.I_COMPENSATEDDATE = A.I_REQDATE AND ROWNUM <= 1
AND C.I_EMPID = A.I_EMPID)
In C int foo()
and int foo(void)
are different functions. int foo()
accepts an arbitrary number of arguments, while int foo(void)
accepts 0 arguments. In C++ they mean the same thing. I suggest that you use void
consistently when you mean no arguments.
If you have a variable a
, extern int a;
is a way to tell the compiler that a
is a symbol that might be present in a different translation unit (C compiler speak for source file), don't resolve it until link time. On the other hand, symbols which are function names are anyway resolved at link time. The meaning of a storage class specifier on a function (extern
, static
) only affects its visibility and extern
is the default, so extern
is actually unnecessary.
I suggest removing the extern
, it is extraneous and is usually omitted.
To check if a specific tab page is the currently selected page of a tab control is easy; just use the SelectedTab property of the tab control:
if (tabControl1.SelectedTab == someTabPage)
{
// Do stuff here...
}
This is more useful if the code is executed based on some event other than the tab page being selected (in which case SelectedIndexChanged would be a better choice).
For example I have an application that uses a timer to regularly poll stuff over TCP/IP connection, but to avoid unnecessary TCP/IP traffic I only poll things that update GUI controls in the currently selected tab page.
If you want to use slf4j simple
, you need these jar
files on your classpath:
If you want to use slf4j
and log4j
, you need these jar
files on your classpath:
No more, no less. Using slf4j simple
, you'll get basic logging to your console at INFO
level or higher. Using log4j
, you must configure it accordingly.
You don't need case
in the where
statement, just use parentheses and or
:
Select * From Times
WHERE StartDate <= @Date AND EndDate >= @Date
AND (
(@day = 'Monday' AND Monday = 1)
OR (@day = 'Tuesday' AND Tuesday = 1)
OR Wednesday = 1
)
Additionally, your syntax is wrong for a case. It doesn't append things to the string--it returns a single value. You'd want something like this, if you were actually going to use a case
statement (which you shouldn't):
Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)
AND 1 = CASE WHEN @day = 'Monday' THEN Monday
WHEN @day = 'Tuesday' THEN Tuesday
ELSE Wednesday
END
And just for an extra umph, you can use the between
operator for your date:
where @Date between StartDate and EndDate
Making your final query:
select
*
from
Times
where
@Date between StartDate and EndDate
and (
(@day = 'Monday' and Monday = 1)
or (@day = 'Tuesday' and Tuesday = 1)
or Wednesday = 1
)
You can do it without writing any code at all :) You just need to set the default value for the column in the database. You can do this in your migrations. For example:
create_table :projects do |t|
t.string :status, :null => false, :default => 'P'
...
t.timestamps
end
Hope that helps.
This works for me, basically the navigation is same
<div id="main-menu">
<ul>
<li><a href="<?php echo base_url();?>shop">SHOP</a>
<li><a href="<?php echo base_url();?>events">EVENTS</a>
<li><a href="<?php echo base_url();?>services">SERVICES</a>
</ul>
</div>
Let's say you're at the URL : http://localhost/project_name/shop/detail_shop/
And you want the "SHOP" li link to get class "active" so you can visually indicate it's the active navigation, even if you're at the sub page of "shop" at "detail_shop".
The javascript :
var path = window.location.pathname;
var str = path.split("/");
var url = document.location.protocol + "//" + document.location.hostname + "/" + str[1] + "/" + str[2];
$('#main-menu a[href="' + url + '"]').parent('li').addClass('active');
Essentially that will match links in the nav who's href attribute begins with "shop" (or whatever the secondary directory happens to be).
If you want to save data that is derived from a Javascript canvas.toDataURL()
function, you have to convert blanks into plusses. If you do not do that, the decoded data is corrupted:
<?php
$encodedData = str_replace(' ','+',$encodedData);
$decocedData = base64_decode($encodedData);
?>
Simplest and flexible solution is below: Inside ${Tomcat_home}/config/server.xml
Change the autoDeploy="false" deployOnStartup="false" under Host element like below This is must.
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="false" deployOnStartup="false">
Add below line under Host element.
<Context path="" docBase="ServletInAction.war" reloadable="true">
<WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
With the above approach we can add as many applications under webapps with different context path names.
If you're getting this, you may have forgotten to put #include <thread>
at the beginning of your file. OP's signature seems like it should work.
I've had this problem many times before with my Galaxy Nexus. Despite having the Android SDK's USB drivers installed, it did not seem to suffice.
I've always solved this by installing a program called PdaNet. While I don't know exactly what it is used for and where it gets its drivers - it comes with the drivers that has always fixed the problem for me. You can uninstall the program itself once it has finished.
Assuming you have the following database tables:
First, you need to create the @Embeddable
holding the composite identifier:
@Embeddable
public class EmployeeId implements Serializable {
@Column(name = "company_id")
private Long companyId;
@Column(name = "employee_number")
private Long employeeNumber;
public EmployeeId() {
}
public EmployeeId(Long companyId, Long employeeId) {
this.companyId = companyId;
this.employeeNumber = employeeId;
}
public Long getCompanyId() {
return companyId;
}
public Long getEmployeeNumber() {
return employeeNumber;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof EmployeeId)) return false;
EmployeeId that = (EmployeeId) o;
return Objects.equals(getCompanyId(), that.getCompanyId()) &&
Objects.equals(getEmployeeNumber(), that.getEmployeeNumber());
}
@Override
public int hashCode() {
return Objects.hash(getCompanyId(), getEmployeeNumber());
}
}
With this in place, we can map the Employee
entity which uses the composite identifier by annotating it with @EmbeddedId
:
@Entity(name = "Employee")
@Table(name = "employee")
public class Employee {
@EmbeddedId
private EmployeeId id;
private String name;
public EmployeeId getId() {
return id;
}
public void setId(EmployeeId id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
The Phone
entity which has a @ManyToOne
association to Employee
, needs to reference the composite identifier from the parent class via two @JoinColumn
mappings:
@Entity(name = "Phone")
@Table(name = "phone")
public class Phone {
@Id
@Column(name = "`number`")
private String number;
@ManyToOne
@JoinColumns({
@JoinColumn(
name = "company_id",
referencedColumnName = "company_id"),
@JoinColumn(
name = "employee_number",
referencedColumnName = "employee_number")
})
private Employee employee;
public Employee getEmployee() {
return employee;
}
public void setEmployee(Employee employee) {
this.employee = employee;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
}
I did a simple test with a formula, X-(X+1)=-1, and the largest value of X I can get to work on Safari, Opera and Firefox (tested on OS X) is 9e15. Here is the code I used for testing:
javascript: alert(9e15-(9e15+1));
Your logic condition is wrong. IIUC, what you want is:
import pyspark.sql.functions as f
df.filter((f.col('d')<5))\
.filter(
((f.col('col1') != f.col('col3')) |
(f.col('col2') != f.col('col4')) & (f.col('col1') == f.col('col3')))
)\
.show()
I broke the filter()
step into 2 calls for readability, but you could equivalently do it in one line.
Output:
+----+----+----+----+---+
|col1|col2|col3|col4| d|
+----+----+----+----+---+
| A| xx| D| vv| 4|
| A| x| A| xx| 3|
| E| xxx| B| vv| 3|
| F|xxxx| F| vvv| 4|
| G| xxx| G| xx| 4|
+----+----+----+----+---+
You can loop through each the cells in your range and use the InStr
function to check if a cell contains a string, in your case; a hyphen.
Sub DeleteRowsWithHyphen()
Dim rng As Range
For Each rng In Range("A2:A10") 'Range of values to loop through
If InStr(1, rng.Value, "-") > 0 Then 'InStr returns an integer of the position, if above 0 - It contains the string
rng.Delete
End If
Next rng
End Sub
A nice simple little jQuery solution:
$("form").bind("keypress", function (e) {
if (e.keyCode == 13) {
return false;
}
});
$array = array( 'one' =>'value', 'two' => 'value2' );
$keys = array_keys($array);
echo $keys[0]; // one
echo $keys[1]; // two
StopWatch will use the high-resolution counter
The Stopwatch measures elapsed time by counting timer ticks in the underlying timer mechanism. If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Otherwise, the Stopwatch class uses the system timer to measure elapsed time. Use the Frequency and IsHighResolution fields to determine the precision and resolution of the Stopwatch timing implementation.
If you're measuring IO then your figures will likely be impacted by external events, and I would worry so much re. exactness (as you've indicated above). Instead I'd take a range of measurements and consider the mean and distribution of those figures.
Just put the condition into the lambda itself, e.g.
animalMap.entrySet().stream()
.forEach(
pair -> {
if (pair.getValue() != null) {
myMap.put(pair.getKey(), pair.getValue());
} else {
myList.add(pair.getKey());
}
}
);
Of course, this assumes that both collections (myMap
and myList
) are declared and initialized prior to the above piece of code.
Update: using Map.forEach
makes the code shorter, plus more efficient and readable, as Jorn Vernee kindly suggested:
animalMap.forEach(
(key, value) -> {
if (value != null) {
myMap.put(key, value);
} else {
myList.add(key);
}
}
);
Difference Between For and For Each Loop in C#
For Loops executes a block of code until an expression returns false while ForEach loop executed a block of code through the items in object collections.
For loop can execute with object collections or without any object collections while ForEach loop can execute with object collections only.
The for loop is a normal loop construct which can be used for multiple purposes where as foreach is designed to work only on Collections or IEnumerables object.
Your code won't work; you need or
instead of ||
.
Try
'0' <= strg[:1] <= '9'
or
strg[:1] in '0123456789'
or, if you are really crazy about startswith
,
strg.startswith(('0', '1', '2', '3', '4', '5', '6', '7', '8', '9'))
You're trying to assign three separate string literals to a single string variable. A valid string variable would be 'John, Sarah, George'
. If you want embedded single quotes between the double quotes, you have to escape them.
Also, your actual SELECT
won't work, because SQL databases won't parse the string variable out into individual literal values. You need to use dynamic SQL instead, and then execute that dynamic SQL statement. (Search this site for dynamic SQL
, with the database engine you're using as the topic (as in [sqlserver] dynamic SQL
), and you should get several examples.)
just close the VS Code to solve the issue for me
As of Python 3.6, you can use f-strings:
list_ = [9.0, 0.052999999999999999,
0.032575399999999997, 0.010892799999999999,
0.055702500000000002, 0.079330300000000006]
print(*[f"{element:.2f}" for element in list_])
#9.00 0.05 0.03 0.01 0.06 0.08
You can use print parameters while keeping code very readable:
print(*[f"{element:.2f}" for element in list_], sep='|', end='<--')
#9.00|0.05|0.03|0.01|0.06|0.08<--
Set a flag on hover:
var over = false;
$('#elem').hover(function() {
over = true;
},
function () {
over = false;
});
Then just check your flag.
All above answers are good. But if you have created "folders" for your jobs, things are slightly different.
Click on the folder under which you want to create a new job. Then click "New Item" on the left menu. Now your "new job" URL will look like this (assuming you are creating the new job under "my-folder"):
http://my-jenkins:8080/job/my-folder/newJob
Under Enter an item name
, enter your desired new job name.
Then use the Copy from
text box at the bottom. Enter job path of he source job.
E.g. If your source job is under folder src-folder
and name of the job is src-job
, you will have to enter src-folder/src-job
in "Copy from" box.
Hope it helps.
If you are using Jackson, then you can use the @JsonProperty
annotation to customize the name of a given JSON property.
Therefore, you just have to annotate the entity fields with the @JsonProperty
annotation and provide a custom JSON property name, like this:
@Entity
public class City {
@Id
@JsonProperty("value")
private Long id;
@JsonProperty("label")
private String name;
//Getters and setters omitted for brevity
}
JSON-B is the standard binding layer for converting Java objects to and from JSON. If you are using JSON-B, then you can override the JSON property name via the @JsonbProperty
annotation:
@Entity
public class City {
@Id
@JsonbProperty("value")
private Long id;
@JsonbProperty("label")
private String name;
//Getters and setters omitted for brevity
}
Give Aquery a try. It has amazingly simple methods to load and cache images asynchronously.
Once you've got an idea, in practice, you may find lombok's @Builder
much more convenient.
@Builder
lets you automatically produce the code required to have your class be instantiable with code such as:
Person.builder()
.name("Adam Savage")
.city("San Francisco")
.job("Mythbusters")
.job("Unchained Reaction")
.build();

I saw some contradictions in the answers above, I just tried the following on Oracle 12c and the following is correct :
LEFT OUTER JOIN
SELECT *
FROM A, B
WHERE A.column = B.column(+)
RIGHT OUTER JOIN
SELECT *
FROM A, B
WHERE B.column(+) = A.column
Try
switch($value) {
case 1:
case 2:
echo "the value is either 1 or 2";
break;
}
An improved version for recursive approach suggested by @schirrmacher to print key[value] for the entire object:
var jDepthLvl = 0;
function visit(object, objectAccessor=null) {
jDepthLvl++;
if (isIterable(object)) {
if(objectAccessor === null) {
console.log("%c ? ? printing object $OBJECT_OR_ARRAY$ -- START ? ?", "background:yellow");
} else
console.log("%c"+spacesDepth(jDepthLvl)+objectAccessor+"%c:","color:purple;font-weight:bold", "color:black");
forEachIn(object, function (accessor, child) {
visit(child, accessor);
});
} else {
var value = object;
console.log("%c"
+ spacesDepth(jDepthLvl)
+ objectAccessor + "[%c" + value + "%c] "
,"color:blue","color:red","color:blue");
}
if(objectAccessor === null) {
console.log("%c ? ? printing object $OBJECT_OR_ARRAY$ -- END ? ?", "background:yellow");
}
jDepthLvl--;
}
function spacesDepth(jDepthLvl) {
let jSpc="";
for (let jIter=0; jIter<jDepthLvl-1; jIter++) {
jSpc+="\u0020\u0020"
}
return jSpc;
}
function forEachIn(iterable, functionRef) {
for (var accessor in iterable) {
functionRef(accessor, iterable[accessor]);
}
}
function isIterable(element) {
return isArray(element) || isObject(element);
}
function isArray(element) {
return element.constructor == Array;
}
function isObject(element) {
return element.constructor == Object;
}
visit($OBJECT_OR_ARRAY$);
There are likely to be many ways to accomplish this. My suggestion is to use Case/When to do it. With 3 columns, it's not too bad.
Select Id,
Case When Col1 < Col2 And Col1 < Col3 Then Col1
When Col2 < Col1 And Col2 < Col3 Then Col2
Else Col3
End As TheMin

The right way is this:
Integer i = Integer.class.cast(obj);
The method cast()
is a much safer alternative to compile-time casting.
You may want to use the onLoad
event, as in the following example:
<iframe src="http://www.google.com/" onLoad="alert('Test');"></iframe>
The alert will pop-up whenever the location within the iframe changes. It works in all modern browsers, but may not work in some very older browsers like IE5 and early Opera. (Source)
If the iframe is showing a page within the same domain of the parent, you would be able to access the location with contentWindow.location
, as in the following example:
<iframe src="/test.html" onLoad="alert(this.contentWindow.location);"></iframe>
.m2 directory on linux box usually would be $HOME/.m2
you could get the $HOME :
echo $HOME
or simply:
cd <enter>
to go to your home directory.

To execute your command directly from within C#, you would use the SqlCommand class.
Quick sample code using paramaterized SQL (to avoid injection attacks) might look like this:
string queryString = "SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName, tPatDBirthday FROM [dbo].[TPatientRaw] WHERE tPatSName = @tPatSName";
string connectionString = "Server=.\PDATA_SQLEXPRESS;Database=;User Id=sa;Password=2BeChanged!;";
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand command = new SqlCommand(queryString, connection);
command.Parameters.AddWithValue("@tPatSName", "Your-Parm-Value");
connection.Open();
SqlDataReader reader = command.ExecuteReader();
try
{
while (reader.Read())
{
Console.WriteLine(String.Format("{0}, {1}",
reader["tPatCulIntPatIDPk"], reader["tPatSFirstname"]));// etc
}
}
finally
{
// Always call Close when done reading.
reader.Close();
}
}
You could also use matrix transposition:
(a.T / row_sums).T
List<Integer> numbers = new TheClassName().myNumbers();
Add the $http, $scope services in the controller fucntion, sometimes if they are missing these errors occur.
ALTER TABLE public.contract_termination_requests
ALTER COLUMN management_company_id DROP NOT NULL;
Bitstorm has the best jquery color animation plugin I've seen. It's an improvement to the jquery color project. It also supports rgba.
First, I see you're using an explicit $.parseJSON()
. If that's because you're manually serializing JSON on the server-side, don't. ASP.NET will automatically JSON-serialize your method's return value and jQuery will automatically deserialize it for you too.
To iterate through the first item in the array you've got there, use code like this:
var firstItem = response.d[0];
for(key in firstItem) {
console.log(key + ':' + firstItem[key]);
}
If there's more than one item (it's hard to tell from that screenshot), then you can loop over response.d
and then use this code inside that outer loop.

Yeah using few API's you can, here is how I like doing it, faced this problem which I was using hibernate core & had to find classes which where annotated with a certain annotation.
Make these an custom annotation using which you will mark which classes you want to be picked up.
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface EntityToBeScanned {
}
Then mark your class with it like
@EntityToBeScanned
public MyClass{
}
Make this utility class which has the following method
public class ClassScanner {
public static Set<Class<?>> allFoundClassesAnnotatedWithEntityToBeScanned(){
Reflections reflections = new Reflections(".*");
Set<Class<?>> annotated = reflections.getTypesAnnotatedWith(EntityToBeScanned.class);
return annotated;
}
}
Call the allFoundClassesAnnotatedWithEntityToBeScanned() method to get a Set of Classes found.

This is the code of my solution base on MasterGaurav solution:
private void launchComponent(String packageName, String name){
Intent launch_intent = new Intent("android.intent.action.MAIN");
launch_intent.addCategory("android.intent.category.LAUNCHER");
launch_intent.setComponent(new ComponentName(packageName, name));
launch_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
activity.startActivity(launch_intent);
}
public void startApplication(String application_name){
try{
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
List<ResolveInfo> resolveinfo_list = activity.getPackageManager().queryIntentActivities(intent, 0);
for(ResolveInfo info:resolveinfo_list){
if(info.activityInfo.packageName.equalsIgnoreCase(application_name)){
launchComponent(info.activityInfo.packageName, info.activityInfo.name);
break;
}
}
}
catch (ActivityNotFoundException e) {
Toast.makeText(activity.getApplicationContext(), "There was a problem loading the application: "+application_name,Toast.LENGTH_SHORT).show();

I had a simple code for Spring Cloud Config
like this:
In application.properties
spring.data.mongodb.db1=mongodb://[email protected]
spring.data.mongodb.db2=mongodb://[email protected]
@Bean(name = "mongoConfig")
@ConfigurationProperties(prefix = "spring.data.mongodb")
public Map<String, Map<String, String>> mongoConfig() {
return new HashMap();
}
@Autowired
@Qualifier(value = "mongoConfig")
private Map<String, String> mongoConfig;
@Bean(name = "mongoTemplates")
public HashMap<String, MongoTemplate> mongoTemplateMap() throws UnknownHostException {
HashMap<String, MongoTemplate> mongoTemplates = new HashMap<>();
for (Map.Entry<String, String>> entry : mongoConfig.entrySet()) {
String k = entry.getKey();
String v = entry.getValue();
MongoTemplate template = new MongoTemplate(new SimpleMongoDbFactory(new MongoClientURI(v)));
mongoTemplates.put(k, template);
}
return mongoTemplates;
}

contentType
is the HTTP header sent to the server, specifying a particular format.dataType
is you telling jQuery what kind of response to expect.The $.ajax()
documentation has full descriptions of these as well.
In your particular case, the first is asking for the response to be in UTF-8
, the second doesn't care. Also the first is treating the response as a JavaScript object, the second is going to treat it as a string.
So the first would be:
success: function(data) {
// get data, e.g. data.title;
}
The second:
success: function(data) {
alert("Here's lots of data, just a string: " + data);
}

A printer doesn't understand pixels, it understand dots (pt in CSS). The best solution is to write an extra CSS for printing, with all of its measures in dots.
Then, in your HTML code, in head section, put:
<link href="style.css" rel="stylesheet" type="text/css" media="screen">
<link href="style_print.css" rel="stylesheet" type="text/css" media="print">
One pattern gobject uses is a variadic function, and enumerated values for each property. The interface looks something like:
update (ID, 1,
BACKUP_ROUTE, 4,
-1); /* -1 terminates the parameter list */
Writing a varargs function is easy -- see http://www.eskimo.com/~scs/cclass/int/sx11b.html. Just match up key -> value pairs and set the appropriate structure attributes.
It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null
.
Given your statement:
img1.ImageUrl = ConfigurationManager
.AppSettings
.Get("Url")
.Replace("###", randomString)
+ Server.UrlEncode(
((System.Web.UI.MobileControls.Form)Page
.FindControl("mobileForm"))
.Title);
I'm guessing either the call to AppSettings.Get("Url")
is returning null because the value isn't found or the call to Page.FindControl("mobileForm")
is returning null because the control isn't found.
You could easily break this out into multiple statements to solve the problem:
var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
as System.Web.UI.MobileControls.Form;
if(configUrl != null && mobileFormControl != null)
{
img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}
sdas is being read as a variable. To input a string you need " "
You can also use:
\usepackage{anyfontsize}
The huge advantage of the anyfontsize
package over scalefnt
is that one does not need to enclose the entire {tikzpicture}
with a \scalefont
environment.
Just adding \usepackage{anyfontsize}
to the preamble is all that is required for the font scaling magic to happen.
I don't think you want to do this. The correct way to use a try
statement in general is as precisely as possible. I think it would be better to do:
try:
do_smth1()
except Stmnh1Exception:
# handle Stmnh1Exception
try:
do_smth2()
except Stmnh2Exception:
# handle Stmnh2Exception
A very belated answer, but I created a Windows Batch file called pythonbat.bat
containing the following:
python.exe %1
@echo off
echo.
pause
and then specified pythonbat.bat
as the default handler for .py
files.
Now, when I double-click a .py
file in File Explorer, it opens a new console window, runs the Python script and then pauses (remains open), until I press any key...
No changes required to any Python scripts.
I can still open a console window and specify python myscript.py
if I want to...
(I just noticed @maurizio already posted this exact answer)
Just move it temporally into a hidden directory (and rename it after, if wanted).

Maybe you installed python from source. In this case, you can recompile python with tcl/tk supported.
/home/xxx/local/tcl-tk/
.# install tcl
wget -c https://prdownloads.sourceforge.net/tcl/tcl8.6.9-src.tar.gz
tar -xvzf tcl8.6.9-src.tar.gz
cd tcl8.6.9
./configure --prefix=/home/xxx/local/tcl-tk/
make
make install
# install tk
wget -c https://prdownloads.sourceforge.net/tcl/tk8.6.9.1-src.tar.gz
tar -xvzf tk8.6.9.1-src.tar.gz
cd tk8.6.9.1
./configure --prefix=/home/xxx/local/tcl-tk/
make
make install
# download the source code of python and decompress it first.
cd <your-python-src-dir>
./configure --prefix=/home/xxx/local/python \
--with-tcltk-includes=/home/xxx/local/tcl-tk/include \
--with-tcltk-libs=/home/xxx/local/tcl-tk/lib

make install
Before I respond to this question, I must explain to you the SERIALIZATION, because if you understand what it means serialization in science computer you can easily understand this keyword.
Serialization
When an object is transferred through the network / saved on physical media(file,...), the object must be "serialized". Serialization converts byte status object series. These bytes are sent on the network/saved and the object is re-created from these bytes.
Example
public class Foo implements Serializable
{
private String attr1;
private String attr2;
...
}
Now IF YOU WANT TO do NOT TRANSFERT/SAVED field of this object SO, you can use keyword transient
private transient attr2;
Easier with inline coding

Actually if you downloaded the icons pack from the android web site, you will see that you have one folder per resolution named drawable-mdpi etc. Copy all folders into the res (not the drawable) folder in Android Studio. This will automatically make all the different resolution of the icon available.
but if your not getting the images from a generator site (maybe your UX team provides them), just make sure your folders are named drawable-hdpi, drawable-mdpi, etc. then in mac select all folders by holding shift and then copy them (DO NOT DRAG). Paste the folders into the res folder. android will take care of the rest and copy all drawables into the correct folder.
In order to include the number of row index "columns" in your total shape I would personally add together the number of columns df.columns.size
with the attribute pd.Index.nlevels
/pd.MultiIndex.nlevels
:
Set up dummy data
import pandas as pd
flat_index = pd.Index([0, 1, 2])
multi_index = pd.MultiIndex.from_tuples([("a", 1), ("a", 2), ("b", 1), names=["letter", "id"])
columns = ["cat", "dog", "fish"]
data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
flat_df = pd.DataFrame(data, index=flat_index, columns=columns)
multi_df = pd.DataFrame(data, index=multi_index, columns=columns)
# Show data
# -----------------
# 3 columns, 4 including the index
print(flat_df)
cat dog fish
id
0 1 2 3
1 4 5 6
2 7 8 9
# -----------------
# 3 columns, 5 including the index
print(multi_df)
cat dog fish
letter id
a 1 1 2 3
2 4 5 6
b 1 7 8 9
Writing our process as a function:
def total_ncols(df, include_index=False):
ncols = df.columns.size
if include_index is True:
ncols += df.index.nlevels
return ncols
print("Ignore the index:")
print(total_ncols(flat_df), total_ncols(multi_df))
print("Include the index:")
print(total_ncols(flat_df, include_index=True), total_ncols(multi_df, include_index=True))
This prints:
Ignore the index:
3 3
Include the index:
4 5
If you want to only include the number of indices if the index is a pd.MultiIndex
, then you can throw in an isinstance
check in the defined function.
As an alternative, you could use df.reset_index().columns.size
to achieve the same result, but this won't be as performant since we're temporarily inserting new columns into the index and making a new index before getting the number of columns.
Use to_datetime
, there is no need for a format string the parser is man/woman enough to handle it:
In [51]:
pd.to_datetime(df['I_DATE'])
Out[51]:
0 2012-03-28 14:15:00
1 2012-03-28 14:17:28
2 2012-03-28 14:50:50
Name: I_DATE, dtype: datetime64[ns]
To access the date/day/time component use the dt
accessor:
In [54]:
df['I_DATE'].dt.date
Out[54]:
0 2012-03-28
1 2012-03-28
2 2012-03-28
dtype: object
In [56]:
df['I_DATE'].dt.time
Out[56]:
0 14:15:00
1 14:17:28
2 14:50:50
dtype: object
You can use strings to filter as an example:
In [59]:
df = pd.DataFrame({'date':pd.date_range(start = dt.datetime(2015,1,1), end = dt.datetime.now())})
df[(df['date'] > '2015-02-04') & (df['date'] < '2015-02-10')]
Out[59]:
date
35 2015-02-05
36 2015-02-06
37 2015-02-07
38 2015-02-08
39 2015-02-09
We have struggle a lot with this issue, and here's what works for us. If you use the conda-forge channel, it's important to make sure you are using updated packages from conda-forge
, even in your Miniconda
root environment.
So install Miniconda, and then do:
conda config --add channels conda-forge --force
conda update --all -y
conda install nb_conda_kernels -y
conda env create -f custom_env.yml -q --force
jupyter notebook
and your custom environment will show up in Jupyter as an available kernel, as long as ipykernel
was listed for installation in your custom_env.yml
file, like this example:
name: bqplot
channels:
- conda-forge
- defaults
dependencies:
- python>=3.6
- bqplot
- ipykernel
Just to prove it working with a bunch of custom environments, here's a screen grab from Windows:
The easiest way to calculate number of neurons in one layer is: Param value / (number of units * 4)

The following SQL statement:

A character set is a subset of all written glyphs. A character encoding specifies how those characters are mapped to numeric values. Some character encodings, like UTF-8 and UTF-16, can encode any character in the Universal Character Set. Others, like US-ASCII or ISO-8859-1 can only encode a small subset, since they use 7 and 8 bits per character, respectively. Because many standards specify both a character set and a character encoding, the term "character set" is often substituted freely for "character encoding".
A collation comprises rules that specify how characters can be compared for sorting. Collations rules can be locale-specific: the proper order of two characters varies from language to language.
Choosing a character set and collation comes down to whether your application is internationalized or not. If not, what locale are you targeting?
In order to choose what character set you want to support, you have to consider your application. If you are storing user-supplied input, it might be hard to foresee all the locales in which your software will eventually be used. To support them all, it might be best to support the UCS (Unicode) from the start. However, there is a cost to this; many western European characters will now require two bytes of storage per character instead of one.
Choosing the right collation can help performance if your database uses the collation to create an index, and later uses that index to provide sorted results. However, since collation rules are often locale-specific, that index will be worthless if you need to sort results according to the rules of another locale.
The height is a 100% unsure, try putting display: block; or display: inline-block;
difference is that int the inner(equi/default)join and natural join that in the natuarl join common column win will be display in single time but inner/equi/default/simple join the common column will be display double time.
Try like this
var results = db.costumers.Where(X=>X.FullName.Contains(FirstName)&&(X=>X.FullName.EndsWith(LastName))
.Select(X=>X);
With ES6, you can now use the spread operator to create a new array with your new elements inserted before the original elements.
// Prepend a single item._x000D_
const a = [1, 2, 3];_x000D_
console.log([0, ...a]);
_x000D_
// Prepend an array._x000D_
const a = [2, 3];_x000D_
const b = [0, 1];_x000D_
console.log([...b, ...a]);
_x000D_
I intended this answer to present an alternative syntax that I think is more memorable and concise. It should be noted that according to some benchmarks (see this other answer), this syntax is significantly slower. This is probably not going to matter unless you are doing many of these operations in a loop.
Or you could use File.AppendAllLines(string, IEnumerable<string>)
File.AppendAllLines(@"C:\Path\file.txt", new[] { "my text content" });

This works great. hope helps someone.
@JuanPieterse has already answered using @Html.ActionLink
so if possible someone can comment or answer using @Url.Action
Here is a solution which blocks all non numeric input from being entered into the text-field.
html
<input type="text" id="numbersOnly" />
javascript
var input = document.getElementById('numbersOnly');
input.onkeydown = function(e) {
var k = e.which;
/* numeric inputs can come from the keypad or the numeric row at the top */
if ( (k < 48 || k > 57) && (k < 96 || k > 105)) {
e.preventDefault();
return false;
}
};?
I personally don't like atoi
function. I would suggest sscanf
:
char myarray[5] = {'-', '1', '2', '3', '\0'};
int i;
sscanf(myarray, "%d", &i);
It's very standard, it's in the stdio.h
library :)
And in my opinion, it allows you much more freedom than atoi
, arbitrary formatting of your number-string, and probably also allows for non-number characters at the end.
EDIT
I just found this wonderful question here on the site that explains and compares 3 different ways to do it - atoi
, sscanf
and strtol
. Also, there is a nice more-detailed insight into sscanf
(actually, the whole family of *scanf
functions).
EDIT2
Looks like it's not just me personally disliking the atoi
function. Here's a link to an answer explaining that the atoi
function is deprecated and should not be used in newer code.
As theMarko suggests:
BASEDIR=$(dirname $0)
echo $BASEDIR
This works unless you execute the script from the same directory where the script resides, in which case you get a value of '.'
To get around that issue use:
current_dir=$(pwd)
script_dir=$(dirname $0)
if [ $script_dir = '.' ]
then
script_dir="$current_dir"
fi
You can now use the variable current_dir throughout your script to refer to the script directory. However this may still have the symlink issue.
You could use tr
, like this:
tr " " .
Example:
# echo "hello world" | tr " " .
hello.world
From man tr
:
DESCRIPTION
Translate, squeeze, and/or delete characters from standard input, writ- ing to standard output.
The current way to do this is by using the "Add Service Reference" command. If you specify "TestUploaderWebService
" as the service reference name, that will generate the type TestUploaderWebService.Service1
. That class will have a method named GetFileListOnWebServer
, which will return an array of strings (you can change that to be a list of strings if you like). You would use it like this:
string[] files = null;
TestUploaderWebService.Service1 proxy = null;
bool success = false;
try
{
proxy = new TestUploaderWebService.Service1();
files = proxy.GetFileListOnWebServer();
proxy.Close();
success = true;
}
finally
{
if (!success)
{
proxy.Abort();
}
}
P.S. Tell your instructor to look at "Microsoft: ASMX Web Services are a “Legacy Technology”", and ask why he's teaching out of date technology.
One simple approach you could take is to compare the length of the original string with that of the string to have whitespaces replaced with nothing. For example:
function hasWhiteSpaces(string) {
if (string.length == string.replace(" ", "").length) {return false}
return true
}
Try this in SQL Server 2008:
select *
from some_table t
where convert(time,t.some_datetime_column) = '5pm'
If you want take a random datetime value and adjust it so the time component is 5pm, then in SQL Server 2008 there are a number of ways. First you need start-of-day (e.g., 2011-09-30 00:00:00.000).
One technique that works for all versions of Microsoft SQL Server as well as all versions of Sybase is to use convert/3
to convert the datetime value to a varchar that lacks a time component and then back into a datetime value:
select convert(datetime,convert(varchar,current_timestamp,112),112)
The above gives you start-of-day for the current day.
In SQL Server 2008, though, you can say something like this:
select start_of_day = t.some_datetime_column
- convert(time, t.some_datetime_column ) ,
from some_table t
which is likely faster.
Once you have start-of-day, getting to 5pm is easy. Just add 17 hours to your start-of-day value:
select five_pm = dateadd(hour,17, t.some_datetime_column
- convert(time,t.some_datetime_column)
)
from some_table t
This line:
public object Hours { get; set; }}
Your have a redundand }
at the end
You can do this with merge
:
df_merged = df1.merge(df2, how='outer', left_index=True, right_index=True)
The keyword argument how='outer'
keeps all indices from both frames, filling in missing indices with NaN
. The left_index
and right_index
keyword arguments have the merge be done on the indices. If you get all NaN
in a column after doing a merge, another troubleshooting step is to verify that your indices have the same dtypes
.
The merge
code above produces the following output for me:
V1 V2
A 2012-01-01 12.0 15.0
2012-02-01 14.0 NaN
2012-03-01 NaN 21.0
B 2012-01-01 15.0 24.0
2012-02-01 8.0 9.0
C 2012-01-01 17.0 NaN
2012-02-01 9.0 NaN
D 2012-01-01 NaN 7.0
2012-02-01 NaN 16.0
Python has a built in method on strings called replace which is used as so:
string.replace(old, new)
So you would use:
string.replace(" ", "_")
I had this problem a while ago and I wrote code to replace characters in a string. I have to start remembering to check the python documentation because they've got built in functions for everything.
NOTE: You may want to remove duplicate items (eg duplicate entries in the same column) before doing these steps to prevent false positives.
A typical custom exception I'd define is something like this:
public class CustomException extends Exception {
public CustomException(String message) {
super(message);
}
public CustomException(String message, Throwable throwable) {
super(message, throwable);
}
}
I even create a template using Eclipse so I don't have to write all the stuff over and over again.
for current year we can use getFullYear() from Date class however there are many function which you can use as per the requirements, some functions are as,
var now = new Date()_x000D_
console.log("Current Time is: " + now);_x000D_
_x000D_
// getFullYear function will give current year _x000D_
var currentYear = now.getFullYear()_x000D_
console.log("Current year is: " + currentYear);_x000D_
_x000D_
// getYear will give you the years after 1990 i.e currentYear-1990_x000D_
var year = now.getYear()_x000D_
console.log("Current year is: " + year);_x000D_
_x000D_
// getMonth gives the month value but months starts from 0_x000D_
// add 1 to get actual month value _x000D_
var month = now.getMonth() + 1_x000D_
console.log("Current month is: " + month);_x000D_
_x000D_
// getDate gives the date value_x000D_
var day = now.getDate()_x000D_
console.log("Today's day is: " + day);
_x000D_
If the modulus (remainder) leftover from dividing by the square root is 0, then it is a perfect square.
def is_square(num: int) -> bool:
return num % math.sqrt(num) == 0
I checked this against a list of perfect squares going up to 1000.
The approach of @AzharShaikh works fine.

But I realize a trouble that TextView will be truncated by word (in default). Show if we have a text like:
test long_line_without_any_space_abcdefgh
the TextView will display:
test...
And I found solution to handle this trouble, replace spaces with the unicode no-break space character, it makes TextView wrap on characters instead of words:
yourString.replace(" ", "\u00A0");
The result:
test long_line_without_any_space_abc...
Use current_url element for Python 2:
print browser.current_url
For Python 3 and later versions of selenium:
print(driver.current_url)
It seems the docs/tool have been updated and you can now add the image
tag to your script. This was successful for me.

Here is the function I use. Created based on @Lauer answer above and some other resources:
//Get Columns
function getColumns($tablenames) {
global $hostname , $dbnames, $username, $password;
try {
$condb = new PDO("mysql:host=$hostname;dbname=$dbnames", $username, $password);
//debug connection
$condb->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$condb->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// get column names
$query = $condb->prepare("DESCRIBE $tablenames");
$query->execute();
$table_names = $query->fetchAll(PDO::FETCH_COLUMN);
return $table_names;
//Close connection
$condb = null;
} catch(PDOExcepetion $e) {
echo $e->getMessage();
}
}
Usage Example:
$columns = getColumns('name_of_table'); // OR getColumns($name_of_table); if you are using variable.
foreach($columns as $col) {
echo $col . '<br/>';
}
df.loc[:,'col':] = df.loc[:,'col':].apply(pd.to_numeric, errors = 'coerce')
This will make folder in sdcard with Folder name you provide.
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Folder name");
if (!file.exists()) {
file.mkdirs();
}
This error occurred for me because mod_rewrite was not enabled. Everything worked fine after enabling the rewrite module: https://www.debuntu.org/how-to-enable-apache-modules-under-debian-based-system-page-2/
My solution is to add this code to the app.php
define('WEB_DIRECTORY', __DIR__);
The problem is that in command line code that uses the constant will break. You can also add the constant to app/console file and the other environment front controllers
Another solution may be add an static method at AppKernel that returns DIR.'/../web/' So you can access everywhere
Try this...
<div class="row">
<div class="col-xs-3">
Menu
</div>
<div class="col-xs-9">
<div class="row">
<div class="col-sm-4 col-sm-push-8">
Right content
</div>
<div class="col-sm-8 col-sm-pull-4">
Content
</div>
</div>
</div>
</div>
This should work!
[HttpPost]
public ActionResult RedirectToImages(int id)
{
return RedirectToAction("Index", "ProductImageManeger", new { id = id });
}
[HttpGet]
public ViewResult Index(int id)
{
return View(_db.ProductImages.Where(rs => rs.ProductId == id).ToList());
}
Notice that you don't have to pass the name of view if you are returning the same view as implemented by the action.
Your view should inherit the model as this:
@model <Your class name>
You can then access your model in view as:
@Model.<property_name>
syntax is of objective c is
returnObj = [object functionName: parameters];
Where object is the object which has the method you're calling. If you're calling it from the same object, you'll use 'self'. This tutorial might help you out in learning Obj-C.
In your case it is simply
[self score];
If you want to pass a parameter then it is like that
- (void)score(int x) {
// some code
}
and I have tried to call it in an other method like this:
- (void)score2 {
[self score:x];
}
In python this work for me
self.set_your_value = "your value"
def your_method_name(self):
self.driver.find_element_by_name(self.set_your_value).send_keys(Keys.TAB)`
Use the properties-maven-plugin to write specific pom properties
to a file at compile time, and then read that file at run time.
In your pom.xml:
<properties>
<name>${project.name}</name>
<version>${project.version}</version>
<foo>bar</foo>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0.0</version>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>write-project-properties</goal>
</goals>
<configuration>
<outputFile>${project.build.outputDirectory}/my.properties</outputFile>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
And then in .java:
java.io.InputStream is = this.getClass().getResourceAsStream("my.properties");
java.util.Properties p = new Properties();
p.load(is);
String name = p.getProperty("name");
String version = p.getProperty("version");
String foo = p.getProperty("foo");
yield(): yield method is used to pause the execution of currently running process so that other waiting thread with the same priority will get CPU to execute.Threads with lower priority will not be executed on yield. if there is no waiting thread then this thread will start its execution.
join(): join method stops currently executing thread and wait for another to complete on which in calls the join method after that it will resume its own execution.

Using __doPostBack
directly is sooooo the 2000s. Anybody coding WebForms in 2018 uses GetPostBackEventReference
(More seriously though, adding this as an answer for completeness. Using the __doPostBack
directly is bad practice (single underscore prefix typically indicates a private member and double indicates a more universal private member), though it probably won't change or become obsolete at this point. We have a fully supported mechanism in ClientScriptManager.GetPostBackEventReference.)
Assuming your btnRefresh is inside our UpdatePanel and causes a postback, you can use GetPostBackEventReference like this (inspiration):
function RefreshGrid() {
<%= ClientScript.GetPostBackEventReference(btnRefresh, String.Empty) %>;
}
The clever sniping in the first set of comments was very amusing, but it really depends on what you are trying to do. If you don't already have the correct library, then 3 lines of code (as in D. Wroblewski's answer) is perfect. OTOH, if you already have the apache.commons library (as most large projects will), then Amar's answer is shorter. OK, it might take you ten minutes to get the library and install it correctly (less than one if you know what you're doing). But the clock is ticking, so you may not have the time to spare. Jarek Przygódzki had an interesting caveat--"If you don't need nested exceptions".
But what if I do need the full stack traces, nested and all? In that case, the secret is to use apache.common's getFullStackTrace (see http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/exception/ExceptionUtils.html#getFullStackTrace%28java.lang.Throwable%29)
It saved my bacon. Thanks, Amar, for the hint!
Following Markus's answer, in newer versions of JS (ES6 I think) you can create a 'struct' factory more simply using Arrow Functions and Rest Parameter like so:
const Struct = (...keys) => ((...v) => keys.reduce((o, k, i) => {o[k] = v[i]; return o} , {}))
const Item = Struct('id', 'speaker', 'country')
var myItems = [
Item(1, 'john', 'au'),
Item(2, 'mary', 'us')
];
console.log(myItems);
console.log(myItems[0].id);
console.log(myItems[0].speaker);
console.log(myItems[0].country);
The result of running this is:
[ { id: 1, speaker: 'john', country: 'au' },
{ id: 2, speaker: 'mary', country: 'us' } ]
1
john
au
You can make it look similar to Python's namedtuple:
const NamedStruct = (name, ...keys) => ((...v) => keys.reduce((o, k, i) => {o[k] = v[i]; return o} , {_name: name}))
const Item = NamedStruct('Item', 'id', 'speaker', 'country')
var myItems = [
Item(1, 'john', 'au'),
Item(2, 'mary', 'us')
];
console.log(myItems);
console.log(myItems[0].id);
console.log(myItems[0].speaker);
console.log(myItems[0].country);
And the results:
[ { _name: 'Item', id: 1, speaker: 'john', country: 'au' },
{ _name: 'Item', id: 2, speaker: 'mary', country: 'us' } ]
1
john
au
I used simple if to check for it
check out my solution
foreach (Pet pet in v.Pets)
{
if (pet == null)
{
Console.WriteLine(" No pet");// enumerator is empty
break;
}
Console.WriteLine(" {0}", pet.Name);
}
Since .NET 4.5 and C# 5.0 you should use Task-based Asynchronous Pattern (TAP) along with async-await keywords in all areas (including the GUI):
TAP is the recommended asynchronous design pattern for new development
instead of Asynchronous Programming Model (APM) and Event-based Asynchronous Pattern (EAP) (the latter includes the BackgroundWorker Class).
Then, the recommended solution for new development is:
Asynchronous implementation of an event handler (Yes, that's all):
private async void Button_Clicked(object sender, EventArgs e)
{
var progress = new Progress<string>(s => label.Text = s);
await Task.Factory.StartNew(() => SecondThreadConcern.LongWork(progress),
TaskCreationOptions.LongRunning);
label.Text = "completed";
}
Implementation of the second thread that notifies the UI thread:
class SecondThreadConcern
{
public static void LongWork(IProgress<string> progress)
{
// Perform a long running work...
for (var i = 0; i < 10; i++)
{
Task.Delay(500).Wait();
progress.Report(i.ToString());
}
}
}
Notice the following:
For a more verbose examples see: The Future of C#: Good things come to those who 'await' by Joseph Albahari.
See also about UI Threading Model concept.
The below snippet is an example of how to handle exceptions and toggle button's Enabled
property to prevent multiple clicks during background execution.
private async void Button_Click(object sender, EventArgs e)
{
button.Enabled = false;
try
{
var progress = new Progress<string>(s => button.Text = s);
await Task.Run(() => SecondThreadConcern.FailingWork(progress));
button.Text = "Completed";
}
catch(Exception exception)
{
button.Text = "Failed: " + exception.Message;
}
button.Enabled = true;
}
class SecondThreadConcern
{
public static void FailingWork(IProgress<string> progress)
{
progress.Report("I will fail in...");
Task.Delay(500).Wait();
for (var i = 0; i < 3; i++)
{
progress.Report((3 - i).ToString());
Task.Delay(500).Wait();
}
throw new Exception("Oops...");
}
}
I prefer to use \n\r. Also I am on a windows system and \n works just fine in my experience.
Since PHP_EOL does not work with regular expressions, and these are the most useful way of dealing with text, then I really never used it or needed to.
Simply create it as new byte[100]
it will be initialized with 0 by default
Dir seems to be very fast.
Sub LoopThroughFiles()
Dim MyObj As Object, MySource As Object, file As Variant
file = Dir("c:\testfolder\")
While (file <> "")
If InStr(file, "test") > 0 Then
MsgBox "found " & file
Exit Sub
End If
file = Dir
Wend
End Sub
In case you were struggling to change linetypes
, the following answer should be helpful. (This is an addition to the solution by Andy W.)
We will try to extend the learned pattern:
cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
line_types <- c("LINE1"=1,"LINE2"=3)
ggplot(data=data,aes(x=a)) +
geom_bar(stat="identity", aes(y=h,fill = "BAR"))+ #green
geom_line(aes(y=b,group=1, colour="LINE1", linetype="LINE1"),size=0.5) + #red
geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=2) + #red
geom_line(aes(y=c,group=1,colour="LINE2", linetype="LINE2"),size=0.5) + #blue
geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=2) + #blue
scale_colour_manual(name="Error Bars",values=cols,
guide = guide_legend(override.aes=aes(fill=NA))) +
scale_linetype_manual(values=line_types)+
scale_fill_manual(name="Bar",values=cols, guide="none") +
ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
ylim(0,1.6) +
theme_bw() +
theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
theme(axis.title.y = element_text(size = 15, vjust=0.3))
However, what we get is the following result:
The problem is that the linetype
is not merged in the main legend.
Note that we did not give any name to the method scale_linetype_manual
.
The trick which works here is to give it the same name as what you used for naming scale_colour_manual
.
More specifically, if we change the corresponding line to the following we get the desired result:
scale_linetype_manual(name="Error Bars",values=line_types)
Now, it is easy to change the size of the line with the same idea.
Note that the geom_bar
has not colour property anymore. (I did not try to fix this issue.) Also, adding geom_errorbar
with colour attribute spoils the result. It would be great if somebody can come up with a better solution which resolves these two issues as well.
It's not a question of preference, but of logic.
x++
increments the value of variable x after processing the current statement.
++x
increments the value of variable x before processing the current statement.
So just decide on the logic you write.
x += ++i
will increment i and add i+1 to x.
x += i++
will add i to x, then increment i.
You're tired and cant do any more work. You eat food. The energy spent looking for food, getting it and actually eating it consumes energy and is overhead!
Overhead is something wasted in order to accomplish a task. The goal is to make overhead very very small.
In computer science lets say you want to print a number, thats your task. But storing the number, the setting up the display to print it and calling routines to print it, then accessing the number from variable are all overhead.
Just return your existing check from a function.
function _isCurl(){
return function_exists('curl_version');
}
In Python, "privacy" depends on "consenting adults'" levels of agreement - you can't force it (any more than you can in real life;-). A single leading underscore means you're not supposed to access it "from the outside" -- two leading underscores (w/o trailing underscores) carry the message even more forcefully... but, in the end, it still depends on social convention and consensus: Python's introspection is forceful enough that you can't handcuff every other programmer in the world to respect your wishes.
((Btw, though it's a closely held secret, much the same holds for C++: with most compilers, a simple #define private public
line before #include
ing your .h
file is all it takes for wily coders to make hash of your "privacy"...!-))
Keyword float
:
<h1 style="text-align:left;float:left;">Title</h1>
<h2 style="text-align:right;float:right;">Context</h2>
<hr style="clear:both;"/>
File.WriteAllText(path, String.Empty);
Alternatively,
File.Create(path).Close();
Some answers don't work with large numbers.
Convert integer to the hex representation, then convert it to bytes:
def int_to_bytes(number):
hrepr = hex(number).replace('0x', '')
if len(hrepr) % 2 == 1:
hrepr = '0' + hrepr
return bytes.fromhex(hrepr)
Result:
>>> int_to_bytes(2**256 - 1)
b'\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff'
Just to clarify -- as noted above when rebasing the sense is reversed, so if you see
<<<<<<< HEAD
foo = 12;
=======
foo = 22;
>>>>>>> [your commit message]
Resolve using 'mine' -> foo = 12
Resolve using 'theirs' -> foo = 22
You should always return the same type on all case condition:
In the first one you have an character and on the else you have an int.
You can use:
Select convert(varchar(11),isnull(totalamount,0))
or if you want with your solution:
Case when total_amount = 0 then '0'
else convert(varchar(11),isnull(total_amount, 0))
end as total_amount
The other methods work fine, but you can also use the good old django.shortcut.redirect
.
The code below was taken from this answer.
In Django 2.x:
from django.shortcuts import redirect
from django.urls import path, include
urlpatterns = [
# this example uses named URL 'hola-home' from app named hola
# for more redirect's usage options: https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/
path('', lambda request: redirect('hola/', permanent=True)),
path('hola/', include('hola.urls')),
]
You can also use the bitwise complement of the array index to step through the array in reverse:
>>> array = [0, 10, 20, 40]
>>> [array[~i] for i, _ in enumerate(array)]
[40, 20, 10, 0]
Whatever you do, don't do it this way ;)
Probably, it will not matter at all. Read this post on Coding Horror ;): http://www.codinghorror.com/blog/archives/001218.html
CSS (or jQuery, for that matter) can't animate between display: none;
and display: block;
. Worse yet: it can't animate between height: 0
and height: auto
. So you need to hard code the height (if you can't hard code the values then you need to use javascript, but this is an entirely different question);
#main-image{
height: 0;
overflow: hidden;
background: red;
-prefix-animation: slide 1s ease 3.5s forwards;
}
@-prefix-keyframes slide {
from {height: 0;}
to {height: 300px;}
}
You mention that you're using Animate.css, which I'm not familiar with, so this is a vanilla CSS.
You can see a demo here: http://jsfiddle.net/duopixel/qD5XX/
"12345".each_char.map(&:to_i)
each_char
does basically the same as split('')
: It splits a string into an array of its characters.
hmmm, I just realize now that in the original question the string contains commas, so my answer is not really helpful ;-(..
These posts helped me get past a couple of issues I had creating a CLR Stored Procedure with Restful API call against Infor M3 API.

Hopefully this provides helpful.
Because it's an integer. You need to declare them as floating point numbers or decimals, or cast to such in the calculation.
One possible solution can be
class Survey{
void renderSurvey(Question q) {
/*
Depending on the type of question (choice, dropdwn or other, I have to render
the question on the UI. The class that calls this doesnt have compile time
knowledge of the type of question that is going to be rendered. Each question
type has its own rendering function. If this is for choice , I need to access
its functions using q.
*/
if(q.getOption() instanceof ChoiceQuestionOption)
{
ChoiceQuestionOption choiceQuestion = (ChoiceQuestionOption)q.getOption();
boolean result = choiceQuestion.getMultiple();
//do something with result......
}
}
}
To answer this point:
I want Sleep to be an async method so it can await other methods
you can maybe rewrite the Sleep
function like this:
private static async Task<int> Sleep(int ms)
{
Console.WriteLine("Sleeping for " + ms);
var task = Task.Run(() => Thread.Sleep(ms));
await task;
Console.WriteLine("Sleeping for " + ms + "END");
return ms;
}
static void Main(string[] args)
{
Console.WriteLine("Starting");
var task1 = Sleep(2000);
var task2 = Sleep(1000);
int totalSlept = task1.Result +task2.Result;
Console.WriteLine("Slept for " + totalSlept + " ms");
Console.ReadKey();
}
running this code will output :
Starting
Sleeping for 2000
Sleeping for 1000
*(one second later)*
Sleeping for 1000END
*(one second later)*
Sleeping for 2000END
Slept for 3000 ms
To add row to JTable
, one of the ways is:
1) Create table using DefaultTableModel:
DefaultTableModel model = new DefaultTableModel();
model.addColumn("Code");
model.addColumn("Name");
model.addColumn("Quantity");
model.addColumn("Unit Price");
model.addColumn("Price");
JTable table = new JTable(model);
2) To add row:
DefaultTableModel model = (DefaultTableModel) table.getModel();
model.addRow(new Object[]{"Column 1", "Column 2", "Column 3","Column 4","Column 5"});
'nunique' is an option for .agg() since pandas 0.20.0, so:
df.groupby('date').agg({'duration': 'sum', 'user_id': 'nunique'})
If you want to do it via setAttribute
you would change the style
attribute like so:
element.setAttribute('style','transform:rotate(90deg); -webkit-transform: rotate(90deg)') //etc
This would be helpful if you want to reset all other inline style and only set your needed style properties' values again, BUT in most cases you may not want that. That's why everybody advised to use this:
element.style.transform = 'rotate(90deg)';
element.style.webkitTransform = 'rotate(90deg)';
The above is equivalent to
element.style['transform'] = 'rotate(90deg)';
element.style['-webkit-transform'] = 'rotate(90deg)';
You can try with this code (Same case)
chaine1 + chaine2;
I suggest you also (I prefer this) the string.concat method
Call this before the query:
set define off;
Alternatively, hacky:
update t set country = 'Trinidad and Tobago' where country = 'trinidad &' || ' tobago';
From Tuning SQL*Plus:
SET DEFINE OFF disables the parsing of commands to replace substitution variables with their values.
This exact question is answered on mySql workbench-faq:
Hover over an acronym to view a description, and see the Section 8.1.11.2, “The Columns Tab” and MySQL CREATE TABLE documentation for additional details.
That means hover over an acronym in the mySql Workbench table editor.
In java.util.timer one can use .cancel()
to stop the timer and clear all pending tasks.
I came across this post and went back to an approach that I used some time ago which is similar to @MadAntrax's.
The main difference is that it uses a VBScript user-defined class to wrap all the logic for switching to CScript and outputting text to the console, so it makes the main script a bit cleaner.
This assumes that your objective is to stream output to the console, rather than having output go to message boxes.
The cCONSOLE class is below. To use it, include the complete class at the end of your script, and then instantiate it right at the beginning of the script. Here is an example:
Option Explicit
'// Instantiate the console object, this automatically switches to CSCript if required
Dim CONS: Set CONS = New cCONSOLE
'// Now we can use the Consol object to write to and read from the console
With CONS
'// Simply write a line
.print "CSCRIPT Console demo script"
'// Arguments are passed through correctly, if present
.Print "Arg count=" & wscript.arguments.count
'// List all the arguments on the console log
dim ix
for ix = 0 to wscript.arguments.count -1
.print "Arg(" & ix & ")=" & wscript.arguments(ix)
next
'// Prompt for some text from the user
dim sMsg : sMsg = .prompt( "Enter any text:" )
'// Write out the text in a box
.Box sMsg
'// Pause with the message "Hit enter to continue"
.Pause
End With

For MongoDB 3.6 and newer:
The $expr
operator allows the use of aggregation expressions within the query language, thus you can leverage the use of $strLenCP
operator to check the length of the string as follows:
db.usercollection.find({
"name": { "$exists": true },
"$expr": { "$gt": [ { "$strLenCP": "$name" }, 40 ] }
})
For MongoDB 3.4 and newer:
You can also use the aggregation framework with the $redact
pipeline operator that allows you to proccess the logical condition with the $cond
operator and uses the special operations $$KEEP
to "keep" the document where the logical condition is true or $$PRUNE
to "remove" the document where the condition was false.
This operation is similar to having a $project
pipeline that selects the fields in the collection and creates a new field that holds the result from the logical condition query and then a subsequent $match
, except that $redact
uses a single pipeline stage which is more efficient.
As for the logical condition, there are String Aggregation Operators that you can use $strLenCP
operator to check the length of the string. If the length is $gt
a specified value, then this is a true match and the document is "kept". Otherwise it is "pruned" and discarded.
Consider running the following aggregate operation which demonstrates the above concept:
db.usercollection.aggregate([
{ "$match": { "name": { "$exists": true } } },
{
"$redact": {
"$cond": [
{ "$gt": [ { "$strLenCP": "$name" }, 40] },
"$$KEEP",
"$$PRUNE"
]
}
},
{ "$limit": 2 }
])
If using $where
, try your query without the enclosing brackets:
db.usercollection.find({$where: "this.name.length > 40"}).limit(2);
A better query would be to to check for the field's existence and then check the length:
db.usercollection.find({name: {$type: 2}, $where: "this.name.length > 40"}).limit(2);
or:
db.usercollection.find({name: {$exists: true}, $where: "this.name.length >
40"}).limit(2);
MongoDB evaluates non-$where
query operations before $where
expressions and non-$where
query statements may use an index. A much better performance is to store the length of the string as another field and then you can index or search on it; applying $where
will be much slower compared to that. It's recommended to use JavaScript expressions and the $where
operator as a last resort when you can't structure the data in any other way, or when you are dealing with a
small subset of data.
A different and faster approach that avoids the use of the $where
operator is the $regex
operator. Consider the following pattern which searches for
db.usercollection.find({"name": {"$type": 2, "$regex": /^.{41,}$/}}).limit(2);
Note - From the docs:
If an index exists for the field, then MongoDB matches the regular expression against the values in the index, which can be faster than a collection scan. Further optimization can occur if the regular expression is a “prefix expression”, which means that all potential matches start with the same string. This allows MongoDB to construct a “range” from that prefix and only match against those values from the index that fall within that range.
A regular expression is a “prefix expression” if it starts with a caret
(^)
or a left anchor(\A)
, followed by a string of simple symbols. For example, the regex/^abc.*/
will be optimized by matching only against the values from the index that start withabc
.Additionally, while
/^a/, /^a.*/,
and/^a.*$/
match equivalent strings, they have different performance characteristics. All of these expressions use an index if an appropriate index exists; however,/^a.*/
, and/^a.*$/
are slower./^a/
can stop scanning after matching the prefix.
I have been working on an open source project that allows you to hot replace classes over and above what hot swap allows: https://github.com/fakereplace/fakereplace
It may or may not work for you, but any feedback is appreciated
Try using a format like %d.%02d
int iAmount = 10050;
printf("The number with fake decimal point is %d.%02d", iAmount/100, iAmount%100);
Another approach is to type cast it to double before printing it using %f like this:
printf("The number with fake decimal point is %0.2f", (double)(iAmount)/100);
My 2 cents :)
If you use GNU find
, since version 4.3.3 you can do:
find -newerct "1 Aug 2013" ! -newerct "1 Sep 2013" -ls
It will accept any date string accepted by GNU date -d
.
You can change the c
in -newerct
to any of a
, B
, c
, or m
for looking at atime/birth/ctime/mtime.
Another example - list files modified between 17:30 and 22:00 on Nov 6 2017:
find -newermt "2017-11-06 17:30:00" ! -newermt "2017-11-06 22:00:00" -ls
Full details from man find
:
-newerXY reference
Compares the timestamp of the current file with reference. The reference argument is normally the name of a file (and one of its timestamps is used
for the comparison) but it may also be a string describing an absolute time. X and Y are placeholders for other letters, and these letters select
which time belonging to how reference is used for the comparison.
a The access time of the file reference
B The birth time of the file reference
c The inode status change time of reference
m The modification time of the file reference
t reference is interpreted directly as a time
Some combinations are invalid; for example, it is invalid for X to be t. Some combinations are not implemented on all systems; for example B is not
supported on all systems. If an invalid or unsupported combination of XY is specified, a fatal error results. Time specifications are interpreted as
for the argument to the -d option of GNU date. If you try to use the birth time of a reference file, and the birth time cannot be determined, a fatal
error message results. If you specify a test which refers to the birth time of files being examined, this test will fail for any files where the
birth time is unknown.
you can use this method just pass your date to it
-(NSString *)getDateFromString:(NSString *)string
{
NSString * dateString = [NSString stringWithFormat: @"%@",string];
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"your current date format"];
NSDate* myDate = [dateFormatter dateFromString:dateString];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"your desired format"];
NSString *stringFromDate = [formatter stringFromDate:myDate];
NSLog(@"%@", stringFromDate);
return stringFromDate;
}
It works !!!! for me on MacOS Sierra 10.12.2
ln -s "/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl" /usr/local/bin/subl
and find it in terminal subl
Button ok= view.findViewById(R.id.btSettingOK);
Fragment me=this;
ok.setOnClickListener( new View.OnClickListener(){
public void onClick(View v){
getActivity().getFragmentManager().beginTransaction().remove(me).commit();
}
});
In mysql 5.7 the auth mechanism changed, documentation can be found in the official manual here.
Using the system root user (or sudo
) you can connect to the mysql database with the mysql 'root' user via CLI.
All other users will work, too.
In phpmyadmin however, all mysql users will work, but not the mysql 'root' user.
This comes from here:
$ mysql -Ne "select Host,User,plugin from mysql.user where user='root';"
+-----------+------+-----------------------+
| localhost | root | auth_socket |
| hostname | root | mysql_native_password |
+-----------+------+-----------------------+
To 'fix' this security feature, do:
mysql -Ne "update mysql.user set plugin='mysql_native_password' where User='root' and Host='localhost'; flush privileges;"
More on this can also be found here in the manual.
You should add a shebang if the script is intended to be executable. You should also install the script with an installing software that modifies the shebang to something correct so it will work on the target platform. Examples of this is distutils and Distribute.
When you have unmanaged resources and you need to make sure they will be cleaned up when your object goes away. Good example would be COM objects or File Handlers.
You should make another XML-spring configuration file in your test resource folder or just copy the old one, it looks fine, but if you're trying to start a web context for testing a micro service, just put the following code as your master test class and inherits from that:
@WebAppConfiguration
@RunWith(SpringRunner.class)
@ContextConfiguration(locations = "classpath*:spring-test-config.xml")
public abstract class AbstractRestTest {
@Autowired
private WebApplicationContext wac;
}
For an unordered list you should use:
[a.count(el) for el in set(a)]
The output is
[4, 4, 2, 1, 2]
I think you could just use the String#length method...
http://ruby-doc.org/core-1.9.3/String.html#method-i-length
Example:
text = 'The quick brown fox jumps over the lazy dog.'
puts text.length > 25 ? 'Too many characters' : 'Accepted'
Can I use a field of the type ... and retrieve it after the GET / POST method ...
Yes (haven't you tried?)
Are there any other ways of using hidden fields in PHP?
You mean other ways of retrieving the value? No.
Of course you can use hidden fields for what ever you want.
Btw. input
fiels have no end tag. So write either just <input ...>
or as self-closing tag <input .../>
.
I did the following :
I would not build or clean build it. Hope that helps you out.
