To get round some of the issues/problems that have ben highlighted I would suggest converting the string to lower case first and then call the ToTitleCase method. You could then use IndexOf(" Mc") or IndexOf(" O\'") to determine special cases that need more specific attention.
inputString = inputString.ToLower();
inputString = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(inputString);
int indexOfMc = inputString.IndexOf(" Mc");
if(indexOfMc > 0)
{
inputString.Substring(0, indexOfMc + 3) + inputString[indexOfMc + 3].ToString().ToUpper() + inputString.Substring(indexOfMc + 4);
}
You may try this
/**
* capitilizeFirst(null) -> ""
* capitilizeFirst("") -> ""
* capitilizeFirst(" ") -> ""
* capitilizeFirst(" df") -> "Df"
* capitilizeFirst("AS") -> "As"
*
* @param str input string
* @return String with the first letter capitalized
*/
public String capitilizeFirst(String str)
{
// assumptions that input parameter is not null is legal, as we use this function in map chain
Function<String, String> capFirst = (String s) -> {
String result = ""; // <-- accumulator
try { result += s.substring(0, 1).toUpperCase(); }
catch (Throwable e) {}
try { result += s.substring(1).toLowerCase(); }
catch (Throwable e) {}
return result;
};
return Optional.ofNullable(str)
.map(String::trim)
.map(capFirst)
.orElse("");
}
Don't overlook the preservation of white space. If you want to process 'fred flinstone'
and you get 'Fred Flinstone'
instead of 'Fred Flinstone'
, you've corrupted your white space. Some of the above solutions will lose white space. Here's a solution that's good for Python 2 and 3 and preserves white space.
def propercase(s):
return ''.join(map(''.capitalize, re.split(r'(\s+)', s)))
If you want to get all Employee name in mysql which having at least one uppercase letter than apply this query.
SELECT * FROM registration WHERE `name` REGEXP BINARY '[A-Z]';
If you use Bootstrap, you can simply add the text-capitalize
helper class:
<p class="text-capitalize">CapiTaliZed text.</p>
EDIT: just in case the link dies again:
Text Transform
Transform text in components with text capitalization classes.
lowercased text.
UPPERCASED TEXT.
CapiTaliZed Text.<p class="text-lowercase">Lowercased text.</p> <p class="text-uppercase">Uppercased text.</p> <p class="text-capitalize">CapiTaliZed text.</p>
Note how text-capitalize only changes the first letter of each word, leaving the case of any other letters unaffected.

If there are more than 1 word in the column, then this will not work as shown below. The UDF mentioned above may help in such case.
mysql> select * from names;

1 row in set (0.00 sec)
Or maybe this one will help...
If the first character is an integer, it will not capitalize the first letter.
>>> '2s'.capitalize()
'2s'
If you want the functionality, strip off the digits, you can use '2'.isdigit()
to check for each character.
>>> s = '123sa'
>>> for i, c in enumerate(s):
... if not c.isdigit():
... break
...
>>> s[:i] + s[i:].capitalize()
'123Sa'
function cap(input) {
return input.replace(/[\.\r\n\t\:\;\?\!]\W*(\w)/g, function(match, capture) {
// For other sentences in the text
return match.toUpperCase();
}).replace(/^\W*\w/, function(match, capture) {
// For the first sentence in the text
return match.toUpperCase();
});;
}
var a = "hi, dear user. it is a simple test. see you later!\r\nbye";
console.log(cap(a));
// Output: Hi, dear user. It is a simple test. See you later!
// Bye
Well, setTimeout
, per its definition, will not hold up the thread. This is desirable, because if it did, it'd freeze the entire UI for the time it was waiting. if you really need to use setTimeout
, then you should be using callback functions:
function myfunction() {
longfunctionfirst(shortfunctionsecond);
}
function longfunctionfirst(callback) {
setTimeout(function() {
alert('first function finished');
if(typeof callback == 'function')
callback();
}, 3000);
};
function shortfunctionsecond() {
setTimeout('alert("second function finished");', 200);
};
If you are not using setTimeout
, but are just having functions that execute for very long, and were using setTimeout
to simulate that, then your functions would actually be synchronous, and you would not have this problem at all. It should be noted, though, that AJAX requests are asynchronous, and will, just as setTimeout
, not hold up the UI thread until it has finished. With AJAX, as with setTimeout
, you'll have to work with callbacks.
In CSS3 paged media this is possible using position: running()
and content: element()
.
Example from the CSS Generated Content for Paged Media Module draft:
@top-center {
content: element(heading);
}
.runner {
position: running(heading);
}
.runner can be any element and heading
is an arbitrary name for the slot.
EDIT: to clarify, there is basically no browser support so this was mostly meant to be for future reference/in addition to the 'practical answers' given already.
Since this question was asked in 2012 and we have come a long way with browser support for flexboxes, I felt as though this answer was obligatory.
If the display of your parent container is flex
, then yes, margin: auto auto
(also known as margin: auto
) will work to center it both horizontally and vertically, regardless if it is an inline
or block
element.
#parent {
width: 50vw;
height: 50vh;
background-color: gray;
display: flex;
}
#child {
margin: auto auto;
}
_x000D_
<div id="parent">
<div id="child">hello world</div>
</div>
_x000D_
Note that the width/height do not have to be specified absolutely, as in this example jfiddle which uses sizing relative to the viewport.
Although browser support for flexboxes is at an all-time high at time of posting, many browsers still do not support it or require vendor prefixes. Refer to http://caniuse.com/flexbox for updated browser support information.
Since this answer received a bit of attention, I would also like to point out that you don't need to specify margin
at all if you're using display: flex
and would like to center all of the elements in the container:
#parent {
width: 50vw;
height: 50vh;
background-color: gray;
display: flex;
align-items: center; /* vertical */
justify-content: center; /* horizontal */
}
_x000D_
<div id="parent">
<div>hello world</div>
</div>
_x000D_

You asked:
wouldn't it be easier to just accept JSON object through normal $_POST and then respond in JSON as well
From the Wikipedia on REST:
RESTful applications maximize the use of the pre-existing, well-defined interface and other built-in capabilities provided by the chosen network protocol, and minimize the addition of new application-specific features on top of it
From what (little) I've seen, I believe this is usually accomplished by maximizing the use of existing HTTP verbs, and designing a URL scheme for your service that is as powerful and self-evident as possible.
Custom data protocols (even if they are built on top of standard ones, such as SOAP or JSON) are discouraged, and should be minimized to best conform to the REST ideology.
SOAP RPC over HTTP, on the other hand, encourages each application designer to define a new and arbitrary vocabulary of nouns and verbs (for example getUsers(), savePurchaseOrder(...)), usually overlaid onto the HTTP 'POST' verb. This disregards many of HTTP's existing capabilities such as authentication, caching and content type negotiation, and may leave the application designer re-inventing many of these features within the new vocabulary.
The actual objects you are working with can be in any format. The idea is to reuse as much of HTTP as possible to expose your operations the user wants to perform on those resource (queries, state management/mutation, deletion).
You asked:
Am I missing something?
There is a lot more to know about REST and the URI syntax/HTTP verbs themselves. For example, some of the verbs are idempotent, others aren't. I didn't see anything about this in your question, so I didn't bother trying to dive into it. The other answers and Wikipedia both have a lot of good information.
Also, there is a lot to learn about the various network technologies built on top of HTTP that you can take advantage of if you're using a truly restful API. I'd start with authentication.
I had such problem. In my case problem was in data - my column 'information' contained 1 unique value and it caused error
UPDATE: to correct work 'pivot' pairs (id_user,information) cannot have duplicates
It works:
df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5],
'information':['phon','phon','phone','phone1','phone','phone1','phone'],
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')
it doesn't work:
df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5],
'information':['phone','phone','phone','phone','phone','phone','phone'],
'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')

jquery offers a variety of methods to hide the div in a timed manner that do not require setting up and later clearing or resetting interval timers or other event handlers. Here are a few examples.
Pure hide, one second delay
// hide in one second
$('#mydiv').delay(1000).hide(0);
Pure hide, no delay
// hide immediately
$('#mydiv').delay(0).hide(0);
Animated hide
// start hide in one second, take 1/2 second for animated hide effect
$('#mydiv').delay(1000).hide(500);
fade out
// start fade out in one second, take 300ms to fade
$('#mydiv').delay(1000).fadeOut(300);
Additionally, the methods can take a queue name or function as a second parameter (depending on method). Documentation for all the calls above and other related calls can be found here: https://api.jquery.com/category/effects/

Using Next.js 9 or above you can get query parameters:
With router
:
import { useRouter } from 'next/router'
const Index = () => {
const router = useRouter()
const {id} = router.query
return(<div>{id}</div>)
}
With getInitialProps
:
const Index = ({id}) => {
return(<div>{id}</div>)
}
Index.getInitialProps = async ({ query }) => {
const {id} = query
return {id}
}
Consider this example:
bool isEqual = (23.42f == 23.42);
What is isEqual
? 9 out of 10 people will say "It's true
, of course" and 9 out of 10 people are wrong: https://rextester.com/RVL15906
That's because floating point numbers are no exact numeric representations.
Being binary numbers, they cannot even exactly represent all numbers that can be exact represented as decimal numbers. E.g. while 0.1
can be exactly represented as a decimal number (it is exactly the tenth part of 1
), it cannot be represented using floating point because it is 0.00011001100110011...
periodic as binary. 0.1
is for floating point what 1/3
is for decimal (which is 0.33333...
as decimal)
The consequence is that calculations like 0.3 + 0.6
can result in 0.89999999999999991
, which is not 0.9
, albeit it's close to that. And thus the test 0.1 + 0.2 - 0.3 == 0.0
might fail as the result of the calculation may not be 0
, albeit it will be very close to 0
.
==
is an exact test and performing an exact test on inexact numbers is usually not very meaningful. As many floating point calculations include rounding errors, you usually want your comparisons to also allow small errors and this is what the test code you posted is all about. Instead of testing "Is A equal to B" it tests "Is A very close to B" as very close is quite often the best result you can expect from floating point calculations.
In my case I faced that error while parsing an email. I got the attachment as base64 string and extract it via re.search. Eventually there was a strange additional substring at the end.

--_=ic0008m4wtZ4TqBFd+sXC8--
When I deleted --_=ic0008m4wtZ4TqBFd+sXC8--
and strip the string then parsing was fixed up.
So my advise is make sure that you are decoding a correct base64 string.
If we have built in functions to convert your integer values to COLOR then why to worry.
string hexValue = string.Format("{0:X}", intColor);
Color brushes = System.Drawing.ColorTranslator.FromHtml("#"+hexValue);
ASCII encoding is 7-bit, but in practice, characters encoded in ASCII are not stored in groups of 7 bits. Instead, one ASCII is stored in a byte, with the MSB usually set to 0 (yes, it's wasted in ASCII).
You can verify this by inputting a string in the ASCII character set in a text editor, setting the encoding to ASCII, and viewing the binary/hex:
Aside: the use of (strictly) ASCII encoding is now uncommon, in favor of UTF-8 (which does not waste the MSB mentioned above - in fact, an MSB of 1 indicates the code point is encoded with more than 1 byte).
just saying:
pod install
- for installing new pods,
pod update
- for updating existing pods,
pod update podName
- for updating only specific pod without touching other pods,
pod update podName versionNum
- for updating / DOWNGRADING specific pod without touching other pods
Way 1: only works for dataURL, not for other types of url.
function dataURLtoFile(dataurl, filename) {
var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
while(n--){
u8arr[n] = bstr.charCodeAt(n);
}
return new File([u8arr], filename, {type:mime});
}
//Usage example:
var file = dataURLtoFile('data:image/png;base64,......', 'a.png');
console.log(file);
Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)
//return a promise that resolves with a File instance
function urltoFile(url, filename, mimeType){
mimeType = mimeType || (url.match(/^data:([^;]+);/)||'')[1];
return (fetch(url)
.then(function(res){return res.arrayBuffer();})
.then(function(buf){return new File([buf], filename, {type:mimeType});})
);
}
//Usage example:
urltoFile('data:image/png;base64,......', 'a.png')
.then(function(file){
console.log(file);
})
Both works in Chrome and Firefox.
For whatever it's worth now: here is yet another solution:
display: inline-block
tabhead
)tabfull
)setTimeout(() => {/*...*/})
to execute code after render / after filling the table with results from fetch
clientWidth
) With a few tweaks, this is the method to use (for brevity / simplicity, I used d3js, the same operations can be done using plain DOM):
setTimeout(() => { // pass one cycle
d3.select('#tabfull')
.style('margin-top', (-1 * d3.select('#tabscroll').select('thead').node().getBoundingClientRect().height) + 'px')
.select('thead')
.style('visibility', 'hidden');
let widths=[]; // really rely on COMPUTED values
d3.select('#tabfull').select('thead').selectAll('th')
.each((n, i, nd) => widths.push(nd[i].clientWidth));
d3.select('#tabhead').select('thead').selectAll('th')
.each((n, i, nd) => d3.select(nd[i])
.style('padding-right', 0)
.style('padding-left', 0)
.style('width', widths[i]+'px'));
})
Waiting on render cycle has the advantage of using the browser layout engine thoughout the process - for any type of header; it's not bound to special condition or cell content lengths being somehow similar. It also adjusts correctly for visible scrollbars (like on Windows)
I've put up a codepen with a full example here: https://codepen.io/sebredhh/pen/QmJvKy
You can use as_json
method. It'll convert your object into hash.
But, that hash will come as a value to the name of that object as a key. In your case,
{'gift' => {'name' => 'book', 'price' => 15.95 }}
If you need a hash that's stored in the object use as_json(root: false)
. I think by default root will be false. For more info refer official ruby guide
http://api.rubyonrails.org/classes/ActiveModel/Serializers/JSON.html#method-i-as_json
In the last answer, you don't need to make a list from numbers; it is already a list:
numbers = [1, 2, 3]
numsum = sum(numbers)
print(numsum)
How about:

Edit: I just found out while debugging that the class is instantiated before every test too. I guess the @BeforeClass annotation is the best here.
You can set up on the constructor too, the test class is a class after all. I'm not sure if it's a bad practice because almost all other methods are annotated, but it works. You could create a constructor like that:
public UT () {
// initialize once here
}
@Test
// Some test here...
The ctor will be called before the tests because they are not static.
In STS/Eclipse go to "project explorer" or "package explorer" and
there is a folder called "server." Open it and you will find server.xml
file. Inside this file at the bottom you find a definition like
<Context docBase="myproject" path="/myproject" reloadable="true"
source="org.eclipse.jst.jee.server:myproject"/>
You might find duplicates of the same definition that you would need to remove.
You were looking for help on installations with pip. You can find it with the following command:
pip install --help
Running pip install -e /path/to/package
installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.
I've seen this kind of thing work in the wild:
<input type="button" th:onclick="'javascript:getContactId(\'' + ${contact.id} + '\');'" />
I use Apache server, so I've used mod_proxy module. Enable modules:
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
Then add:
ProxyPass /your-proxy-url/ http://service-url:serviceport/
Finally, pass proxy-url to your script.
As a supplementary, on Amazon EC2, what I need to do is:
sudo yum install freetype-devel
sudo yum install libpng-devel
sudo pip install matplotlib
Right-click the project, select Properties then under 'Configuration properties | Linker | Input | Ignore specific Library and write msvcrtd.lib
Use the CREATE TABLE SELECT syntax.
http://dev.mysql.com/doc/refman/5.0/en/create-table-select.html
CREATE TABLE new_tbl SELECT * FROM orig_tbl;
I needed this instead of using padding because I used inline-block containers to display a series of individual events in a workflow timeline. The last event in the timeline needed no arrow after it.
Ended up with something like:
.transaction-tile:after {
content: "\f105";
}
.transaction-tile:last-child:after {
content: "\00a0";
}
Used fontawesome for the gt (chevron) character. For whatever reason "content: none;" was producing alignment issues on the last tile.
__str__
is only called when a string representation is required of an object.
For example str(uno)
, print "%s" % uno
or print uno
However, there is another magic method called __repr__
this is the representation of an object. When you don't explicitly convert the object to a string, then the representation is used.
If you do this uno.neighbors.append([[str(due),4],[str(tri),5]])
it will do what you expect.

I've created the visualization which should help to understand the idea. Semaphore controls access to a common resource in a multithreading environment.
ExecutorService executor = Executors.newFixedThreadPool(7);
Semaphore semaphore = new Semaphore(4);
Runnable longRunningTask = () -> {
boolean permit = false;
try {
permit = semaphore.tryAcquire(1, TimeUnit.SECONDS);
if (permit) {
System.out.println("Semaphore acquired");
Thread.sleep(5);
} else {
System.out.println("Could not acquire semaphore");
}
} catch (InterruptedException e) {
throw new IllegalStateException(e);
} finally {
if (permit) {
semaphore.release();
}
}
};
// execute tasks
for (int j = 0; j < 10; j++) {
executor.submit(longRunningTask);
}
executor.shutdown();
Output
Semaphore acquired
Semaphore acquired
Semaphore acquired
Semaphore acquired
Could not acquire semaphore
Could not acquire semaphore
Could not acquire semaphore
Sample code from the article
The one liner : bind()
to own address, connect()
to remote address.
Quoting from the man page of bind()
bind() assigns the address specified by addr to the socket referred to by the file descriptor sockfd. addrlen specifies the size, in bytes, of the address structure pointed to by addr. Traditionally, this operation is called "assigning a name to a socket".
and, from the same for connect()
The connect() system call connects the socket referred to by the file descriptor sockfd to the address specified by addr.
To clarify,
bind()
associates the socket with its local address [that's why
server side bind
s, so that clients can use that address to connect
to server.]connect()
is used to connect to a remote [server] address, that's
why is client side, connect [read as: connect to server] is used.JavaScript just got the new Object.fromEntries
method.
function mapObject (obj, fn) {_x000D_
return Object.fromEntries(_x000D_
Object_x000D_
.entries(obj)_x000D_
.map(fn)_x000D_
)_x000D_
}_x000D_
_x000D_
const myObject = { a: 1, b: 2, c: 3 }_x000D_
const myNewObject = mapObject(myObject, ([key, value]) => ([key, value * value]))_x000D_
console.log(myNewObject)
_x000D_
The code above converts the Object into an nested Array ([[<key>,<value>], ...]
) wich you can map over. Object.fromEntries
converts the Array back to an Object.
The cool thing about this pattern, is that you can now easily take object keys into account while mapping.
Object.fromEntries
is currently only supported by these browsers/engines, nevertheless there are polyfills available (e.g @babel/polyfill).
In general you can use pandas rename function here. Given your dataframe you could change to a new name like this. If you had more columns you could also rename those in the dictionary. The 0 is the current name of your column
import pandas as pd
import numpy as np
e = np.random.normal(size=100)
e_dataframe = pd.DataFrame(e)
e_dataframe.rename(index=str, columns={0:'new_column_name'})
I had a CASE statement with WHEN column = 'sometext & more text' THEN ....
I replaced it with WHEN column = 'sometext ' || CHR(38) || ' more text' THEN ...
you could also use WHEN column LIKE 'sometext _ more text' THEN ...
(_ is the wildcard for a single character)
ColumnNames
is a property of type List<String>
so when you are setting up you need to pass a List<String>
in the Returns
call as an argument (or a func which return a List<String>
)
But with this line you are trying to return just a string
input.SetupGet(x => x.ColumnNames).Returns(temp[0]);
which is causing the exception.
Change it to return whole list:
input.SetupGet(x => x.ColumnNames).Returns(temp);
May be it's obvious for expert users of MYSQL but I wasted some time while trying to figure out default value would not export functions. So I thought to mention here that --routines param needs to be set to true to make it work.
mysqldump --routines=true -u <user> my_database > my_database.sql
Using pdfbox we can achive this
Example :
public static void main(String args[]) {
PDFParser parser = null;
PDDocument pdDoc = null;
COSDocument cosDoc = null;
PDFTextStripper pdfStripper;
String parsedText;
String fileName = "E:\\Files\\Small Files\\PDF\\JDBC.pdf";
File file = new File(fileName);
try {
parser = new PDFParser(new FileInputStream(file));
parser.parse();
cosDoc = parser.getDocument();
pdfStripper = new PDFTextStripper();
pdDoc = new PDDocument(cosDoc);
parsedText = pdfStripper.getText(pdDoc);
System.out.println(parsedText.replaceAll("[^A-Za-z0-9. ]+", ""));
} catch (Exception e) {
e.printStackTrace();
try {
if (cosDoc != null)
cosDoc.close();
if (pdDoc != null)
pdDoc.close();
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
I came by the same error on an old 2010 Exchange Server. A service(Exchange mailbox replication service) was giving out the above error and the migration process could not be continued. Searching through the internet, i came by this link which stated the below:
The Exchange GRE fails to open when installed for the first time or if any changes are made to the IIS server. It fails with snap-in error and when you try to open the snap-in page, the following content is displayed:
This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. If your service is being hosted in IIS you can fix the problem by setting 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'."
Cause: This error occurs because http port number 443 is already in use by another application and the IIS server is not configured to handle multiple binding to the same port.
Solution: Configure IIS server to handle multiple port bindings. Contact the vendor (Microsoft) to configure it.
Since these services were offered from an IIS Web Server, checking the Bindings on the Root Site fixed the problem. Someone had messed up the Site Bindings, defining rules that were overlapping themselves and messed up the services.
Fixing the correct Bindings resolved the problem, in my case, and i did not have to configure the Web.Config.
The answers from @unbeli and @Niklas are good, but @unbeli's answer does not work for all hex strings and it is desirable to do the decoding without importing an extra library (codecs). The following should work (but will not be very efficient for large strings):
>>> result = bytes.fromhex((lambda s: ("%s%s00" * (len(s)//2)) % tuple(s))('4a82fdfeff00')).decode('utf-16-le')
>>> result == '\x4a\x82\xfd\xfe\xff\x00'
True
Basically, it works around having invalid utf-8 bytes by padding with zeros and decoding as utf-16.
Method 1:
Update ListView in the your xml layout activity/fragment:
<ListView
...
android:choiceMode="singleChoice"
android:listSelector="@android:color/darker_gray"
/>
That's it, you're done!
If you want a programmatic way to handle this then use method 2...
Method 2:
If you're using a ListFragment you can override onListItemClick(), using the view to set the colour. Save the current View selected to reset the colour of the last selection.
Please note, this only works on listviews that fit on one screen, as the view is recycled.
public class MyListFragment extends ListFragment {
View previousSelectedItem;
...
@Override
public void onListItemClick(ListView parent, View v, int position, long id) {
super.onListItemClick(parent, v, position, id);
if (previousSelectedItem!=null) {
previousSelectedItem.setBackgroundColor(Color.WHITE);
}
previousSelectedItem=v;
v.setBackgroundColor(Color.BLUE);
}
}
You can use inline css :
<td style = "text-align: center;">
Entity interface
public interface Entity<I> extends Serializable {
/**
* @return entity identity
*/
I getId();
/**
* @return HashCode of entity identity
*/
int identityHashCode();
/**
* @param other
* Other entity
* @return true if identities of entities are equal
*/
boolean identityEquals(Entity<?> other);
}
Basic implementation for all Entities, simplifies Equals/Hashcode implementations:
public abstract class AbstractEntity<I> implements Entity<I> {
@Override
public final boolean identityEquals(Entity<?> other) {
if (getId() == null) {
return false;
}
return getId().equals(other.getId());
}
@Override
public final int identityHashCode() {
return new HashCodeBuilder().append(this.getId()).toHashCode();
}
@Override
public final int hashCode() {
return identityHashCode();
}
@Override
public final boolean equals(final Object o) {
if (this == o) {
return true;
}
if ((o == null) || (getClass() != o.getClass())) {
return false;
}
return identityEquals((Entity<?>) o);
}
@Override
public String toString() {
return getClass().getSimpleName() + ": " + identity();
// OR
// return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}
Room Entity impl:
@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;
@Column(name = "number")
private String number; //immutable
@Column(name = "capacity")
private Integer capacity;
@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable
Room() {
// default constructor
}
public Room(Building building, String number) {
// constructor with required field
notNull(building, "Method called with null parameter (application)");
notNull(number, "Method called with null parameter (name)");
this.building = building;
this.number = number;
}
public Integer getId(){
return id;
}
public Building getBuilding() {
return building;
}
public String getNumber() {
return number;
}
public void setCapacity(Integer capacity) {
this.capacity = capacity;
}
//no setters for number, building nor id
}
I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).
If you are using Maven, add the below config in your pom.xml:
<build>
<testResources>
<testResource>
<directory>src/main/webapp</directory>
</testResource>
</testResources>
</build>
With this config, you will be able to access xml files in WEB-INF folder. From Maven POM Reference: The testResources element block contains testResource elements. Their definitions are similar to resource elements, but are naturally used during test phases.
You can examine the url through several Request
fields:
Imagine your application is listening on the following application root:
http://www.example.com/myapplication
And a user requests the following URI:
http://www.example.com/myapplication/foo/page.html?x=y
In this case the values of the above mentioned attributes would be the following:
path /foo/page.html full_path /foo/page.html?x=y script_root /myapplication base_url http://www.example.com/myapplication/foo/page.html url http://www.example.com/myapplication/foo/page.html?x=y url_root http://www.example.com/myapplication/
You can easily extract the host part with the appropriate splits.
Make sure that the component has the "exported" flag set to true. Also the component defining the permission should be installed before the component that uses it.
I also had this question and found two more things very useful:
So I use something like this on the command line (OSX 10.9):
ping www.goooooogle.com & PING_PID=$(pgrep 'ping'); SECONDS=0; while pgrep -q 'ping'; do sleep 0.2; if [ $SECONDS = 10 ]; then kill $PING_PID; fi; done
As this is a loop I included a "sleep 0.2" to keep the CPU cool. ;-)
(BTW: ping is a bad example anyway, you just would use the built-in "-t" (timeout) option.)
You don't need to change the delimiter to display the right part of the string with cut
.
The -f
switch of the cut
command is the n-TH element separated by your delimiter : :
, so you can just type :
grep puddle2_1557936 | cut -d ":" -f2
Another solutions (adapt it a bit) if you want fun :
Using grep :
grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or still with look around regex
grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or with perl :
perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or using ruby (thanks to glenn jackman)
ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or with awk :
awk -F'puddle2_1557936:' '{print $2}' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or with python :
python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or using only bash :
IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2
js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2
php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'

For both crypto & noncrypto, efficiently:
private static readonly Random _random = new Random();
public static string GenerateRandomString(int length, string charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890") =>
RandomString(_random.NextBytes, length, charset.ToCharArray());
public static string GenerateRandomCryptoString(int length, string charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890")
{
using (var crypto = new System.Security.Cryptography.RNGCryptoServiceProvider())
return RandomString(crypto.GetBytes, length, charset.ToCharArray());
}
private static string RandomString(Action<byte[]> fillRandomBuffer, int length, char[] charset)
{
if (length < 0)
throw new ArgumentOutOfRangeException(nameof(length), $"{nameof(length)} must be greater or equal to 0");
if (charset is null)
throw new ArgumentNullException(nameof(charset));
if (charset.Length == 0)
throw new ArgumentException($"{nameof(charset)} must contain at least 1 character", nameof(charset));
var maxIdx = charset.Length;
var chars = new char[length];
var randomBuffer = new byte[length * 4];
fillRandomBuffer(randomBuffer);
for (var i = 0; i < length; i++)
chars[i] = charset[BitConverter.ToUInt32(randomBuffer, i * 4) % maxIdx];
return new string(chars);
}
Using generators & LINQ. Not the fastest option (especially because it doesn't generate all the bytes in one go) but pretty neat & extensible:
private static readonly Random _random = new Random();
public static string GenerateRandomString(int length, string charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890") =>
new string(_random.GetGenerator().RandomChars(charset.ToCharArray()).Take(length).ToArray());
public static string GenerateRandomCryptoString(int length, string charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890")
{
using (var crypto = new System.Security.Cryptography.RNGCryptoServiceProvider())
return new string(crypto.GetGenerator().RandomChars(charset.ToCharArray()).Take(length).ToArray());
}
public static IEnumerable<char> RandomChars(this Func<uint, IEnumerable<uint>> randomGenerator, char[] charset)
{
if (charset is null)
throw new ArgumentNullException(nameof(charset));
if (charset.Length == 0)
throw new ArgumentException($"{nameof(charset)} must contain at least 1 character", nameof(charset));
return randomGenerator((uint)charset.Length).Select(r => charset[r]);
}
public static Func<uint, IEnumerable<uint>> GetGenerator(this Random random)
{
if (random is null)
throw new ArgumentNullException(nameof(random));
return GeneratorFunc_Inner;
IEnumerable<uint> GeneratorFunc_Inner(uint maxValue)
{
if (maxValue > int.MaxValue)
throw new ArgumentOutOfRangeException(nameof(maxValue));
return Generator_Inner();
IEnumerable<uint> Generator_Inner()
{
var randomBytes = new byte[4];
while (true)
{
random.NextBytes(randomBytes);
yield return BitConverter.ToUInt32(randomBytes, 0) % maxValue;
}
}
}
}
public static Func<uint, IEnumerable<uint>> GetGenerator(this System.Security.Cryptography.RNGCryptoServiceProvider random)
{
if (random is null)
throw new ArgumentNullException(nameof(random));
return Generator_Inner;
IEnumerable<uint> Generator_Inner(uint maxValue)
{
var randomBytes = new byte[4];
while (true)
{
random.GetBytes(randomBytes);
yield return BitConverter.ToUInt32(randomBytes, 0) % maxValue;
}
}
}
a simpler version using LINQ for only non-crypto strings:
private static readonly Random _random = new Random();
public static string RandomString(int length, string charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890") =>
new string(_random.GenerateChars(charset).Take(length).ToArray());
public static IEnumerable<char> GenerateChars(this Random random, string charset)
{
if (charset is null) throw new ArgumentNullException(nameof(charset));
if (charset.Length == 0) throw new ArgumentException($"{nameof(charset)} must contain at least 1 character", nameof(charset));
return random.Generator(charset.Length).Select(r => charset[r]);
}
public static IEnumerable<int> Generator(this Random random, int maxValue)
{
if (random is null) throw new ArgumentNullException(nameof(random));
return Generator_Inner();
IEnumerable<int> Generator_Inner() { while (true) yield return random.Next(maxValue); }
}
This would also work:
// callback function
function tryMe (param1, param2) {
alert (param1 + " and " + param2);
}
// callback executer
function callbackTester (callback) {
callback();
}
// test function
callbackTester (function() {
tryMe("hello", "goodbye");
});
Another Scenario :
// callback function
function tryMe (param1, param2, param3) {
alert (param1 + " and " + param2 + " " + param3);
}
// callback executer
function callbackTester (callback) {
//this is the more obivous scenario as we use callback function
//only when we have some missing value
//get this data from ajax or compute
var extraParam = "this data was missing" ;
//call the callback when we have the data
callback(extraParam);
}
// test function
callbackTester (function(k) {
tryMe("hello", "goodbye", k);
});
Java documentation is helpful to know the root cause of a particular IOException.
Just have a look at the direct known sub-interfaces of IOException
from the documentation page:
ChangedCharSetException, CharacterCodingException, CharConversionException, ClosedChannelException, EOFException, FileLockInterruptionException, FileNotFoundException, FilerException, FileSystemException, HttpRetryException, IIOException, InterruptedByTimeoutException, InterruptedIOException, InvalidPropertiesFormatException, JMXProviderException, JMXServerErrorException, MalformedURLException, ObjectStreamException, ProtocolException, RemoteException, SaslException, SocketException, SSLException, SyncFailedException, UnknownHostException, UnknownServiceException, UnsupportedDataTypeException, UnsupportedEncodingException, UserPrincipalNotFoundException, UTFDataFormatException, ZipException
Most of these exceptions are self-explanatory.
A few IOExceptions
with root causes:
EOFException: Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal the end of the stream.
SocketException: Thrown to indicate that there is an error creating or accessing a Socket.
RemoteException: A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.
UnknownHostException: Thrown to indicate that the IP address of a host could not be determined (you may not be connected to Internet).
MalformedURLException: Thrown to indicate that a malformed URL has occurred. Either no legal protocol could be found in a specification string or the string could not be parsed.
On github there is also a secret way...
You can filter commits by author in the commit view by appending param ?author=github_handle
. For example, the link https://github.com/dynjs/dynjs/commits/master?author=jingweno shows a list of commits to the Dynjs project

This was a test that ran each scenario 10,000,000 times. :-)
Co-ercion is 0 + "123"
Casting is (integer)"123"
I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123')
is a fatal error in PHP. You might want your code to check the type of the supplied value.
My test code is below.
function test_string_coerce($s) {

You could also solve it with an interface default method:
@Query(select p from Person p where p.forename = :forename and p.surname = :surname)
User findByForenameAndSurname(@Param("surname") String lastname,
@Param("forename") String firstname);
default User findByName(Name name) {

Of course you'd still have the actual repository function publicly visible...
it will print log messages in your developer console (firebug/webkit dev tools/ie dev tools)
You can convert the QString type to python string by just using the str
function. Assuming you are not using any Unicode characters you can get a python
string as below:
text = str(combobox1.currentText())
If you are using any unicode characters, you can do:
text = unicode(combobox1.currentText())
I cloned the simple_list_item_1
(Alt + Click) and placed the copy on my res/layout
folder, renamed it to list_white_text.xml
with this contents:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:textColor="@color/abc_primary_text_material_dark"
android:minHeight="?android:attr/listPreferredItemHeightSmall" />
The android:textColor="@color/abc_primary_text_material_dark"
translates to white on my device.
then in the java
code:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_white_text, myList);
Source code of clear shows the reason why the newly added data gets the first position.
public void clear() {
modCount++;
// Let gc do its work
for (int i = 0; i < size; i++)
elementData[i] = null;
size = 0;
}
clear() is faster than removeAll() by the way, first one is O(n) while the latter is O(n_2)
Try using jQuery for the event listener, it will then work in Firefox.
myAudio = new Audio('someSound.ogg');
$(myAudio).bind('ended', function() {
myAudio.currentTime = 0;
myAudio.play();
});
myAudio.play();
Something like that.
When you are transitioning between Fragments, call addToBackStack()
as part of your FragmentTransaction
:
FragmentTransaction tx = fragmentManager.beginTransation();
tx.replace( R.id.fragment, new MyFragment() ).addToBackStack( "tag" ).commit();
If you require more detailed control (i.e. when some Fragments are visible, you want to suppress the back key) you can set an OnKeyListener
on the parent view of your fragment:
//You need to add the following line for this solution to work; thanks skayred
fragment.getView().setFocusableInTouchMode(true);
fragment.getView().requestFocus();
fragment.getView().setOnKeyListener( new OnKeyListener()
{
@Override
public boolean onKey( View v, int keyCode, KeyEvent event )
{
if( keyCode == KeyEvent.KEYCODE_BACK )
{
return true;
}
return false;
}
} );
Directly from ngStyle
docs:
Expression which evals to an object whose keys are CSS style names and values are corresponding values for those CSS keys.
<div ng-style="{'width': '20px', 'height': '20px', ...}"></div>
So you could do this:
<div ng-style="{'background-color': data.backgroundCol}"></div>
Hope this helps!
Another approach using linq is:
foreach ( int number in numbers.Skip(1))
{
// process number
}
If you want to skip the first in a number of items.
Or use .SkipWhere
if you want to specify a condition for skipping.
You can use a regular expression or some manual string fiddling, but I think I prefer:
date("d/m/Y", strtotime($str));
I notice you are using windows, which is particularly bad about using low port numbers for outgoing sockets. See here for how to reserve the port number that you want to rely on using for glassfish.
For the SQL statement, you also have to specify the column list. For eg.
INSERT INTO tbl (idcol1,col2) VALUES ( value1,value2)
instead of
INSERT INTO tbl VALUES ( value1,value2)
I searched for a the same solution with a variable instead of the String.
I hope i can help someone with my solution :)
var numb = "3";
$(`#myid[data-tab-id=${numb}]`);
This might not be relevant to your specific problem, but the error message you mentioned has many causes, one of them is using a return type for an [OperationContract] that is either abstract, interface, or not known to the WCF client code.
Check the post (and solution) below
I know it's an old question, but it's a good one, so how about this?
unsigned short int x = 65529U;
short int y = *(short int*)&x;
printf("%d\n", y);
If you are planning to hide show some span based on click event which is initially hidden with style="display:none" then .toggle() is best option to go with.
$("span").toggle();
Reasons : Each time you don't need to check whether the style is already there or not. .toggle() will take care of that automatically and hide/show span based on current state.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="button" value="Toggle" onclick="$('#hiddenSpan').toggle();"/>_x000D_

It looks like you want the return
keyword
def check_ping():
hostname = "taylor"
response = os.system("ping -c 1 " + hostname)
# and then check the response...
if response == 0:
pingstatus = "Network Active"
else:
pingstatus = "Network Error"
return pingstatus
You need to capture/'receive' the return value of the function(pingstatus) in a variable with something like:
pingstatus = check_ping()
NOTE: ping -c
is for Linux, for Windows use ping -n

It's probably worth going through a good introductory tutorial to Python, which will cover all the fundamentals. I recommend investigating Udacity.com and codeacademy.com
Since this appeared to be a breaking change introduced in version 10 of pip, I downgraded to a compatible version:
pip install 'pip<10'
This command tells pip to install a version of the module lower than version 10. Do this in a virutalenv so you don't screw up your site installation of Python.
Dirty fix.
android:paddingTop="10dp"
android:drawableTop="@drawable/ic_src"
Figuring right padding solve the purpose. However, for varied screen, use different padding and put that in dimens resource in respective value folder.
String array[]=new String[]; and String array[]=new String[]{};
No difference,these are just different ways of declaring array
String array=new String[10]{}; got error why ?
This is because you can not declare the size of the array in this format.
right way is
String array[]=new String[]{"a","b"};
As a visual person, I like to weigh in with a sequence diagram of the proxy pattern. If you don't know how to read the arrows, I read the first one like this: Client

The problem with merge sort is the merge, if you don't actually need to implement the merge, then it is pretty simple (for a vector of ints):
#include <algorithm>
#include <vector>
using namespace std;
typedef vector<int>::iterator iter;
void mergesort(iter b, iter e) {
if (e -b > 1) {
iter m = b + (e -b) / 2;
mergesort(b, m);
mergesort(m, e);
inplace_merge(b, m, e);
}
}
To receive the new commits
git fetch
Reset
You can reset the commit for a local branch using git reset
.
To change the commit of a local branch:
git reset origin/master --hard
Be careful though, as the documentation puts it:
Resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded.
If you want to actually keep whatever changes you've got locally - do a --soft
reset instead. Which will update the commit history for the branch, but not change any files in the working directory (and you can then commit them).
Rebase
You can replay your local commits on top of any other commit/branch using git rebase
:
git rebase -i origin/master
This will invoke rebase in interactive mode where you can choose how to apply each individual commit that isn't in the history you are rebasing on top of.
If the commits you removed (with git push -f
) have already been pulled into the local history, they will be listed as commits that will be reapplied - they would need to be deleted as part of the rebase or they will simply be re-included into the history for the branch - and reappear in the remote history on the next push.
Use the help git command --help
for more details and examples on any of the above (or other) commands.
As of NuGet 2.8, there is a feature to downgrade a package.
Example:
The following command entered into the Package Manager Console will downgrade the Couchbase client to version 1.3.1.0.
Update-Package CouchbaseNetClient -Version 1.3.1.0
Result:
Updating 'CouchbaseNetClient' from version '1.3.3' to '1.3.1.0' in project [project name].
Removing 'CouchbaseNetClient 1.3.3' from [project name].
Successfully removed 'CouchbaseNetClient 1.3.3' from [project name].
Something to note as per crimbo below:
This approach doesn't work for downgrading from one prerelease version to other prerelease version - it only works for downgrading to a release version
If no access specifier is given, it's package-level access (there is no explicit specifier for this) for classes and class members. Interface methods are implicitly public.
This happens when your result is not a result (but a "false" instead). You should change this line
$sql = 'SELECT * FROM $usertable WHERE PartNumber = $partid';
to this:
$sql = "SELECT * FROM $usertable WHERE PartNumber = $partid";
because the " can interprete $variables while ' cannot.
Works fine with integers (numbers), for strings you need to put the $variable in single quotes, like
$sql = "SELECT * FROM $usertable WHERE PartNumber = '$partid' ";
If you want / have to work with single quotes, then php CAN NOT interprete the variables, you will have to do it like this:
$sql = 'SELECT * FROM '.$usertable.' WHERE string_column = "'.$string.'" AND integer_column = '.$number.';
Pass a duration to show()
and hide()
:
When a duration is provided,
.show()
becomes an animation method.
E.g. element.delay(1000).show(0)
Though you might hope that browsers would support ISO 8601 (or date-only subsets thereof), this is not the case. All browsers that I know of (at least in the US/English locales I use) are able to parse the horrible US MM/DD/YYYY
format.
If you already have the parts of the date, you might instead want to try using Date.UTC(). If you don't, but you must use the YYYY-MM-DD
format, I suggest using a regular expression to parse the pieces you know and then pass them to Date.UTC()
.
Download and run the following script to recursively convert soft tabs to hard tabs in plain text files.
Place and execute the script from inside the folder which contains the plain text files.
#!/bin/bash
find . -type f -and -not -path './.git/*' -exec grep -Iq . {} \; -and -print | while read -r file; do {
echo "Converting... "$file"";
data=$(unexpand --first-only -t 4 "$file");
rm "$file";
echo "$data" > "$file";
}; done;
Make sure you plug the Arduino directly into the computer and not through a hub. Using a hub will give you this error.
A NullPointerException means that one of the variables you are passing is null, but the code tries to use it like it is not.
For example, If I do this:
Integer myInteger = null;
int n = myInteger.intValue();
The code tries to grab the intValue of myInteger, but since it is null, it does not have one: a null pointer exception happens.
What this means is that your getTask method is expecting something that is not a null, but you are passing a null. Figure out what getTask needs and pass what it wants!
Try out this as well. Your page will refresh every 10sec

WebKit supports scrollbar pseudo elements that can be hidden with standard CSS rules:
#element::-webkit-scrollbar {
display: none;
}
If you want all scrollbars hidden, use
::-webkit-scrollbar {
display: none;
}
I'm not sure about restoring - this did work, but there might be a right way to do it:
::-webkit-scrollbar {
display: block;
}
You can of course always use width: 0
, which can then be easily restored with width: auto
, but I'm not a fan of abusing width
for visibility tweaks.
Firefox 64 now supports the experimental scrollbar-width property by default (63 requires a configuration flag to be set). To hide the scrollbar in Firefox 64:
#element {
scrollbar-width: none;
}
To see if your current browser supports either the pseudo element or scrollbar-width
, try this snippet:

Since the Logical Address space is 32-bit long that means program size is 2^32 bytes i.e. 4GB. Now we have the page size of 4KB i.e.2^12 bytes.Thus the number of pages in program are 2^20.(no. of pages in program = program size/page size).Now the size of page table entry is 4 byte hence the size of page table is 2^20*4 = 4MB(size of page table = no. of pages in program * page table entry size). Hence 4MB space is required in Memory to store the page table.
Try below code,
UIView *view1 = [[UIView alloc]init];
view1.backgroundColor = [UIColor blackColor];
[view1 setFrame:CGRectMake(0, 0, 50, 50)];
UIView *view2 = [[UIView alloc]init];
view2.backgroundColor = [UIColor greenColor];
[view2 setFrame:CGRectMake(0, 100, 100, 100)];
NSArray *subView = [NSArray arrayWithObjects:view1,view2, nil];
[self.stack1 initWithArrangedSubviews:subView];
Hope it works. Please let me know if you need anymore clarification.

the same rules should apply to Java.
in your case it means output of integer values in 2 or more digits, the first being zero if number less than or equal to 9
Put it in a separate, custom header.
Overloading the standard HTTP headers is probably going to cause more confusion than it's worth, and will violate the principle of least surprise. It might also lead to interoperability problems for your API client programmers who want to use off-the-shelf tool kits that can only deal with the standard form of typical HTTP headers (such as Authorization
).
I actually implemented this in PHP using the Guzzle client to make a client library for the api, but the concept should work for other platforms.
Basically, I issue two tokens, a short (5 minute) one and a long one that expires after a week. The client library uses middleware to attempt one refresh of the short token if it receives a 401 response to some request. It will then try the original request again and if it was able to refresh gets the correct response, transparently to the user. If it failed, it will just send the 401 up to the user.
If the short token is expired, but still authentic and the long token is valid and authentic, it will refresh the short token using a special endpoint on the service that the long token authenticates (this is the only thing it can be used for). It will then use the short token to get a new long token, thereby extending it another week every time it refreshes the short token.
This approach also allows us to revoke access within at most 5 minutes, which is acceptable for our use without having to store a blacklist of tokens.
Late edit: Re-reading this months after it was fresh in my head, I should point out that you can revoke access when refreshing the short token because it gives an opportunity for more expensive calls (e.g. call to the database to see if the user has been banned) without paying for it on every single call to your service.
I've achieved the same thing before by using subqueries. So if your original table was called StoreCountsByWeek, and you had a separate table that listed the Store IDs, then it would look like this:
SELECT StoreID,
Week1=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=1),
Week2=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=2),
Week3=(SELECT ISNULL(SUM(xCount),0) FROM StoreCountsByWeek WHERE StoreCountsByWeek.StoreID=Store.StoreID AND Week=3)
FROM Store
ORDER BY StoreID
One advantage to this method is that the syntax is more clear and it makes it easier to join to other tables to pull other fields into the results too.
My anecdotal results are that running this query over a couple of thousand rows completed in less than one second, and I actually had 7 subqueries. But as noted in the comments, it is more computationally expensive to do it this way, so be careful about using this method if you expect it to run on large amounts of data .
If you want to do it the way you showed in your question, this is a way to do it inline
class YourClass: UIViewController{
@IBOutlet weak var tableView: UITableView!
//other IBOutlets
//THIS is how you declare a UIImageView inline
let placeholderImage : UIImageView = {
let placeholderImage = UIImageView(image: UIImage(named: "nophoto"))
placeholderImage.contentMode = .scaleAspectFill
return placeholderImage
}()
var someVariable: String!
var someOtherVariable: Int!
func someMethod(){
//method code
}
//and so on
}
There is a difference how web driver handles different windows and how it handles different tabs.
Case 1:
In case there are multiple windows, then the following code can help:
//Get the current window handle
String windowHandle = driver.getWindowHandle();
//Get the list of window handles
ArrayList tabs = new ArrayList (driver.getWindowHandles());
System.out.println(tabs.size());
//Use the list of window handles to switch between windows
driver.switchTo().window(tabs.get(0));
//Switch back to original window
driver.switchTo().window(mainWindowHandle);
Case 2:
In case there are multiple tabs in the same window, then there is only one window handle. Hence switching between window handles keeps the control in the same tab.
In this case using Ctrl + \t (Ctrl + Tab) to switch between tabs is more useful.
//Open a new tab using Ctrl + t
driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL +"t");
//Switch between tabs using Ctrl + \t
driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL +"\t");
Detailed sample code can be found here:
http://design-interviews.blogspot.com/2014/11/switching-between-tabs-in-same-browser-window.html
For a horizontal progress bar, you first need to define your progress bar and link it with your XML file like this, in the onCreate
:
final TextView txtview = (TextView)findViewById(R.id.tV1);
final ProgressBar pbar = (ProgressBar) findViewById(R.id.pB1);
Then, you may use onProgressChanged Method in your WebChromeClient:
MyView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
if(progress < 100 && pbar.getVisibility() == ProgressBar.GONE){
pbar.setVisibility(ProgressBar.VISIBLE);
txtview.setVisibility(View.VISIBLE);
}
pbar.setProgress(progress);
if(progress == 100) {
pbar.setVisibility(ProgressBar.GONE);
txtview.setVisibility(View.GONE);
}
}
});
After that, in your layout you have something like this
<TextView android:text="Loading, . . ."
android:textAppearance="?android:attr/textAppearanceSmall"
android:id="@+id/tV1" android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textColor="#000000"></TextView>
<ProgressBar android:id="@+id/pB1"
style="?android:attr/progressBarStyleHorizontal" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_centerVertical="true"
android:padding="2dip">
</ProgressBar>
This is how I did it in my app.
It is the bitwise xor operator in java which results 1 for different value (ie 1 ^ 0 = 1) and 0 for same value (ie 0 ^ 0 = 0).
The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND
command on another connection, but it apparently was "not opening [it] up in sync with the client side".
Well, the main reason would be there was no synchronisation whatsoever. Calling:
cs.send("SEND " + FILE)
cs.close()
would just place the data into a OS buffer; close
would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep
after close
might mitigate the problem, but this is not synchronisation.
The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK
, or better PORT 36250
to indicate where to connect). This would make sure the server is already listening.
The other thing is you must check the return values of send
to make sure how many bytes was taken from your buffer. Or use sendall
.
(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)

You do need to loop through it. C++ does not implement any simpler way to do this when you are dealing with primitive type arrays.

In my case, the folder which served the files was a symbolic link to another folder, made with
ln -sf /origin /var/www/destination
Even though the permissions (user and group) where correct on the destination folder (the symbolic link), I still had the error because Nginx needed to have permissions to the origin folder whole's hierarchy as well.
I use
pidof X && echo "yup X server is running"
pgrep and $DISPLAY are other options.
Other considerations:
su then $DISPLAY will not be set. Things that change the environment of the program running can make this not work.
I don't recommand ps -e | grep X as this will find procX, which is not the X server.
If you add the extension .SH
to the environment variable PATHEXT
, you will be able to run shell scripts from PowerShell by only using the script name with arguments:
PS> .\script.sh args
If you store your scripts in a directory that is included in your PATH environment variable, you can run it from anywhere, and omit the extension and path:
PS> script args
Note: sh.exe or another *nix shell must be associated with the .sh extension.
You can use net stop http
it will display which process is using. Moslty world wide web services are using

I was having the same issue in asp.NET razor C#
I had a ComboBox
filled with titles from an EventMessage
, and I wanted to show the Content of this message with its selected value to show it in a label or TextField
or any other Control
...
My ComboBox
was filled like this:
@Html.DropDownList("EventBerichten", new SelectList(ViewBag.EventBerichten, "EventBerichtenID", "Titel"), new { @class = "form-control", onchange = "$(this.form).submit();" })
In my EventController
I had a function to go to the page, in which I wanted to show my ComboBox
(which is of a different model type, so I had to use a partial view)?
The function to get from index to page in which to load the partial view:
public ActionResult EventDetail(int id)
{
Event eventOrg = db.Event.Include(s => s.Files).SingleOrDefault(s => s.EventID == id);
// EventOrg eventOrg = db.EventOrgs.Find(id);
if (eventOrg == null)
{
return HttpNotFound();
}
ViewBag.EventBerichten = GetEventBerichtenLijst(id);
ViewBag.eventOrg = eventOrg;
return View(eventOrg);
}
The function for the partial view is here:
public PartialViewResult InhoudByIdPartial(int id)
{
return PartialView(
db.EventBericht.Where(r => r.EventID == id).ToList());
}
The function to fill EventBerichten:
public List<EventBerichten> GetEventBerichtenLijst(int id)
{
var eventLijst = db.EventBericht.ToList();
var berLijst = new List<EventBerichten>();
foreach (var ber in eventLijst)
{
if (ber.EventID == id )
{
berLijst.Add(ber);
}
}
return berLijst;
}
The partialView Model looks like this:
@model IEnumerable<STUVF_back_end.Models.EventBerichten>
<table>
<tr>
<th>
EventID
</th>
<th>
Titel
</th>
<th>
Inhoud
</th>
<th>
BerichtDatum
</th>
<th>
BerichtTijd
</th>
</tr>
@foreach (var item in Model)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.EventID)
</td>
<td>
@Html.DisplayFor(modelItem => item.Titel)
</td>
<td>
@Html.DisplayFor(modelItem => item.Inhoud)
</td>
<td>
@Html.DisplayFor(modelItem => item.BerichtDatum)
</td>
<td>
@Html.DisplayFor(modelItem => item.BerichtTijd)

</tr>
}

Converting your value in milliseconds to days is simply (MsValue / 86,400,000)
We can get 1/1/1970 as numeric value by DATE(1970,1,1)
= (MsValueCellReference / 86400000) + DATE(1970,1,1)
Using your value of 1271664970687 and formatting it as dd/mm/yyyy hh:mm:ss
gives me a date and time of 19/04/2010 08:16:11
A quicker faster version would use mt_rand:
$min=1;
$max=20;
echo mt_rand($min,$max);
Source: http://www.php.net/manual/en/function.mt-rand.php.
NOTE: Your server needs to have the Math PHP module enabled for this to work. If it doesn't, bug your host to enable it, or you have to use the normal (and slower) rand().
Option #1: You can come up with a new UI design that does not require simultaneous horizontal and vertical scrolling.
Option #2: You can obtain the source code to ScrollView
and HorizontalScrollView
, learn how the core Android team implemented those, and create your own BiDirectionalScrollView
implementation.
Option #3: You can get rid of the dependencies that are requiring you to use the widget system and draw straight to the Canvas.
Option #4: If you stumble upon an open source application that seems to implement what you seek, look to see how they did it.
e.which doesn't work in IE try e.keyCode, also you probably want to use keydown() instead of keypress() if you are targeting IE.

I had a problem where I had to round up only and these answers didnt work for how I had to have my code run so I used a different method. The INT function rounds towards negative (4.2 goes to 4, -4.2 goes to -5) Therefore, I changed my function to negative, applied the INT function, then returned it to positive simply by multiplying it by -1 before and after
Count = -1 * (int(-1 * x))

What? Use file open, seek position then stream erase line using null.
Gotch it? Simple,stream,no array that eat memory,fast.
This work on vb.. Example search line culture=id where culture are namevalue and id are value and we want to change it to culture=en
Fileopen(1, "text.ini")
dim line as string
dim currentpos as long
while true
line = lineinput(1)
dim namevalue() as string = split(line, "=")
if namevalue(0) = "line name value that i want to edit" then
currentpos = seek(1)
fileclose()
dim fs as filestream("test.ini", filemode.open)
dim sw as streamwriter(fs)
fs.seek(currentpos, seekorigin.begin)
sw.write(null)
sw.write(namevalue + "=" + newvalue)
sw.close()
fs.close()
exit while
end if
msgbox("org ternate jua bisa, no line found")
end while
that's all..use #d
Assuming the ID is unique:
var result = xmldoc.Element("Customers")
.Elements("Customer")

You could also use First

or Where
, instead of Single

In June 2018, in an effort to raise security and comply with modern standards, the insecure TLS 1.0 & 1.1 protocols will no longer be supported for SSL connections to Central. This should only affect users of Java 6 (and Java 7) that are also using https to access central, which by our metrics is less than .2% of users.
For more details and workarounds, see the blog and faq here: https://blog.sonatype.com/enhancing-ssl-security-and-http/2-support-for-central
If you are trying to do this, it means you are doing something wrong. Consider using a dict
instead.
def show_val(vals, name):
print "Name:", name, "val:", vals[name]
vals = {'a': 1, 'b': 2}
show_val(vals, 'b')
Output:
Name: b val: 2
You can use a CancellationToken
to control whether the task gets cancelled. Are you talking about aborting it before it's started ("nevermind, I already did this"), or actually interrupting it in middle? If the former, the CancellationToken
can be helpful; if the latter, you will probably need to implement your own "bail out" mechanism and check at appropriate points in the task execution whether you should fail fast (you can still use the CancellationToken to help you, but it's a little more manual).
MSDN has an article about cancelling Tasks: http://msdn.microsoft.com/en-us/library/dd997396.aspx

Sounds like you really want a Dictionary<int, string>
or possibly a switch
statement...
You can do it with the conditional operator though:
userType = user.Type == 0 ? "Admin"
: user.Type == 1 ? "User"
: user.Type == 2 ? "Employee"
: "The default you didn't specify";
While you could put that in one line, I'd strongly urge you not to.
I would normally only do this for different conditions though - not just several different possible values, which is better handled in a map.
I use the following formula that extends previous answers:
class A(object):
def __init__(self):
print "world"
class B(A):
def __init__(self):
print "hello"
super(self.__class__, self).__init__()
B()
This way you don't have to repeat the name of the class in the call to super. It can come handy if you are coding a large number of classes, and want to make your code in the initialiser methods independent of the class name.
Keep in mind that you have to exactly specify your path to your language.JSON like this:
language: {
url: '/mywebsite/js/localisation/German.json'
}
Even I faced the same issue with my domain. If I gave an IP address it was working. But with a domain name it was not.
Then I checked my DNS A record. The domain had multiple entries with different IP addresses assigned. I removed all the wrong values, and it worked. Just one more check list if anyone faces a similar issue.

Since you are going to use this in a login page. Here is a code I used in a Login page using Material-UI
<Grid
container
spacing={0}
direction="column"
alignItems="center"
justify="center"
style={{ minHeight: '100vh' }}
>
<Grid item xs={3}>
<LoginForm />
</Grid>
</Grid>
this will make this login form at the center of the screen.
But still IE doesn't support the Material-UI Grid and you will see some misplaced content in IE.
Hope this will help you.
Clearing screen in Java is not supported, but you can try some hacks to achieve this.
a) Use OS-depends command, like this for Windows:
Runtime.getRuntime().exec("cls");
b) Put bunch of new lines (this makes ilusion that screen is clear)
c) If you ever want to turn off System.out, you can try this:
System.setOut(new PrintStream(new OutputStream() {
@Override public void write(int b) throws IOException {}
}));
Use build job plugin for that task in order to trigger other jobs from jenkins file. You can add variety of logic to your execution such as parallel ,node and agents options and steps for triggering external jobs. I gave some easy-to-read cookbook example for that.
1.example for triggering external job from jenkins file with conditional example:
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueOfParam2')
]
}
2.example triggering multiple jobs from jenkins file with conditionals example:
def jobs =[
'job1Title'{
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueNameOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueNameOfParam2')
]
}
},
'job2Title'{
if (env.GIT_COMMIT == 'someCommitHashToPerformAdditionalTest') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam3',value: 'valueOfParam3')
booleanParam(name: 'keyNameOfParam4',value:'valueNameOfParam4')
booleanParam(name: 'keyNameOfParam5',value:'valueNameOfParam5')
]
}
}
You can simply check whether the multisets with the elements of x and y are equal:
import collections
collections.Counter(x) == collections.Counter(y)
This requires the elements to be hashable; runtime will be in O(n)
, where n
is the size of the lists.
If the elements are also unique, you can also convert to sets (same asymptotic runtime, may be a little bit faster in practice):
set(x) == set(y)
If the elements are not hashable, but sortable, another alternative (runtime in O(n log n)
) is
sorted(x) == sorted(y)
If the elements are neither hashable nor sortable you can use the following helper function. Note that it will be quite slow (O(n²)
) and should generally not be used outside of the esoteric case of unhashable and unsortable elements.
def equal_ignore_order(a, b):
""" Use only when elements are neither hashable nor sortable! """
unmatched = list(b)
for element in a:
try:
unmatched.remove(element)
except ValueError:
return False
return not unmatched
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
}

You can also create an overload of ShowDialog in your child class that gets an out parameter that returns you the result.
public partial class FormOptions : Form
{
public DialogResult ShowDialog(out string result)
{
DialogResult dialogResult = base.ShowDialog();
result = m_Result;
return dialogResult;
}
}
I was also adding the wrong assembly during initialization. The class I'm persisting is in assembly #1, and my .hbm.xml file is embedded in assembly #2. I changed cfg.AddAssembly(...

System.web.http.webhost not found.
You just need to copy the system.web.http.webhost
file from your main project which you run in Visual Studio and paste it into your published project bin
directory.
After this it may show the same error but the directory name is changed it may be system.web.http
. Follow same procedure as above. It will work after all the files are uploaded. This due to the nuget package in Visual Studio they download from the internet but on server it not able to download it.
You can find this file in your project bin
directory.
The most trivial way to upload a file over SFTP with JSch is:
JSch jsch = new JSch();
Session session = jsch.getSession(user, host);
session.setPassword(password);
session.connect();
ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
sftpChannel.connect();
sftpChannel.put("C:/source/local/path/file.zip", "/target/remote/path/file.zip");
Similarly for a download:
sftpChannel.get("/source/remote/path/file.zip", "C:/target/local/path/file.zip");
You may need to deal with UnknownHostKey
exception.
Do display: inline-block
:
#report-upload-form label {
padding-left:26px;
width:125px;
text-transform: uppercase;
display:inline-block
}
Another cause is accidentally putting the data=...
inside the aes(...)
instead of outside:
RIGHT:
ggplot(data=df[df$var7=='9-06',], aes(x=lifetime,y=rep_rate,group=mdcp,color=mdcp) ...)
WRONG:
ggplot(aes(data=df[df$var7=='9-06',],x=lifetime,y=rep_rate,group=mdcp,color=mdcp) ...)
In particular this can happen when you prototype your plot command with qplot()
, which doesn't use an explicit aes()
, then edit/copy-and-paste it into a ggplot()
qplot(data=..., x=...,y=..., ...)
ggplot(data=..., aes(x=...,y=...,...))
It's a pity ggplot's error message isn't Missing 'data' argument! instead of this cryptic nonsense, because that's what this message often means.

//but i cannot really get the id and assign it to an array that is not with in the scope?(or can I)
Yes, you can!
var IDs = [];
$("#mydiv").find("span").each(function(){ IDs.push(this.id); });
This is the beauty of closures.
Note that while you were on the right track, sighohwell and cletus both point out more reliable and concise ways of accomplishing this, taking advantage of attribute filters (to limit matched elements to those with IDs) and jQuery's built-in map()
function:
var IDs = $("#mydiv span[id]") // find spans with ID attribute
.map(function() { return this.id; }) // convert to set of IDs
.get(); // convert to instance of Array (optional)
Throwing my version into the pile here:
import argparse
parser = argparse.ArgumentParser()
args = parser.parse_args()
if not vars(args):
parser.print_help()
parser.exit(1)
You may notice the parser.exit
- I mainly do it like that because it saves an import line if that was the only reason for sys

on Windows if MySQL is install as a service you can change the binpath of the service. For example
sc config MySQL57 binPath= "\"C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqld.exe\" --defaults-file=\"<myini path>" MySQL57"
space after binpath is important. You must escape double quotes
It would be nice if there were some way of turning off "throw on non-success code" but if you catch WebException you can at least use the response:
using System;
using System.IO;
using System.Web;
using System.Net;
public class Test
{
static void Main()
{
WebRequest request = WebRequest.Create("http://csharpindepth.com/asd");
try
{
using (WebResponse response = request.GetResponse())
{
Console.WriteLine("Won't get here");
}
}
catch (WebException e)
{
using (WebResponse response = e.Response)
{
HttpWebResponse httpResponse = (HttpWebResponse) response;
Console.WriteLine("Error code: {0}", httpResponse.StatusCode);
using (Stream data = response.GetResponseStream())
using (var reader = new StreamReader(data))
{
string text = reader.ReadToEnd();
Console.WriteLine(text);
}
}
}
}
}
You might like to encapsulate the "get me a response even if it's not a success code" bit in a separate method. (I'd suggest you still throw if there isn't a response, e.g. if you couldn't connect.)
If the error response may be large (which is unusual) you may want to tweak HttpWebRequest.DefaultMaximumErrorResponseLength
to make sure you get the whole error.

XStream is pretty good at serializing object to XML without much configuration and money! (it's under BSD license).
We used it in one of our project to replace the plain old java-serialization and it worked almost out of the box.
Although I'm not sure why you want to create CSS classes with JavaScript, here is an option:
var style = document.createElement('style');
style.type = 'text/css';

document.getElementsByTagName('head')[0].appendChild(style);
document.getElementById('someElementId').className = 'cssClass';

Similar to @joran's answer. Reshape the df so that the prices for each product are in different columns:
xx <- reshape(df, idvar=c("skew","version","color"),
v.names="price", timevar="product", direction="wide")
xx will have columns price.p1, ... price.p4, so:
ggp <- ggplot(xx,aes(x=price.p1, y=price.p3, color=factor(skew))) +
geom_point(shape=19, size=5)
ggp + facet_grid(color~version)
gives the result from your image.
You can use the following rule to redirect from https to http :
RewriteEngine On
RewriteCond %{HTTPS} ^on$
RewriteRule ^(.*)$ http://example.com/$1 [NC,L,R]
Explanation :
RewriteCond %{HTTPS} ^on$
Checks if the HTTPS is on (Request is made using https)
Then
RewriteRule ^(.*)$ http://example.com/$1 [NC,L,R]
Redirect any request (https://example.com/foo) to http://example.com/foo .
$1 is part of the regex in RewriteRule pattern, it contains whatever value was captured in (.+) , in this case ,it captures the full request_uri everything after the domain name.
[NC,L,R] are the flags, NC makes the uri case senstive, you can use both uppercase or lowercase letters in the request.
L flag tells the server to stop proccessing other rules if the currunt rule has matched, it is important to use the L flag to avoid rule confliction when you have more then on rules in a block.
R flag is used to make an external redirection.
I'm currently working with Eclipse Luna. And had the same problem. You might want to verify the compiler compliance settings, go to "Project/Properties/Java Compiler"
The Compiler compliance level was set to 1.4, I set mine to 1.5,(and I'm working with the JDK 1.8); it worked for me.
And if you had to change the setting; it might be useful to go to "Window/Preferences/Java/Compiler" And check to see that the Compiler compliance level is 1.5 or higher. Just in case you have a need to do another Java project.
Well if you're happy printing it in decimal, you could just make it positive by masking:
int positive = bytes[i] & 0xff;
If you're printing out a hash though, it would be more conventional to use hex. There are plenty of other questions on Stack Overflow addressing converting binary data to a hex string in Java.
While the others answers are correct in so far as they show what a mere +
usually does (namely, leave the number as it is, if it is one), they are incomplete in so far as they don't explain what happens.
To be exact, +x
evaluates to x.__pos__()
and ++x
to x.__pos__().__pos__()
.
I could imagine a VERY weird class structure (Children, don't do this at home!) like this:
class ValueKeeper(object):
def __init__(self, value): self.value = value
def __str__(self): return str(self.value)
class A(ValueKeeper):
def __pos__(self):
print 'called A.__pos__'
return B(self.value - 3)
class B(ValueKeeper):
def __pos__(self):
print 'called B.__pos__'
return A(self.value + 19)
x = A(430)
print x, type(x)
print +x, type(+x)
print ++x, type(++x)
print +++x, type(+++x)
I would do this in CSS:
div.centered {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
then in HTML:
<div class="centered"></div>
JavaScript btoa() function can be used to convert data into base64 encoded string
BLOB :
BLOB
(Binary Large Object) is a large object data type in the database system. BLOB
could store a large chunk of data, document types and even media files like audio or video files. BLOB
fields allocate space only whenever the content in the field is utilized. BLOB
allocates spaces in Giga Bytes.
USAGE OF BLOB :
You can write a binary large object (BLOB
) to a database as either binary or character data, depending on the type of field at your data source. To write a BLOB
value to your database, issue the appropriate INSERT or UPDATE
statement and pass the BLOB
value as an input parameter. If your BLOB
is stored as text, such as a SQL Server text field, you can pass the BLOB
as a string parameter. If the BLOB
is stored in binary format, such as a SQL Server image field, you can pass an array of type byte as a binary parameter.
A useful link : Storing documents as BLOB in Database - Any disadvantages ?
Whenever we do queries to get some data, it is returned as an object. Then most of us convert it to array for looping through the rows easily. In php "empty()" function is used to check if an array is empty i.e. if it has no data in it. So we can check if returned array representation of query isn't empty by doing like this
if(!empty($result)){
//DO STUFF
}
It probably works with Javascript. When you click the link, nothing happens because it points to the current site. The javascript will then load a window or an url. It's used a lot in AJAX web apps.
Ubuntu these days comes with ufw - Uncomplicated Firewall. ufw is an easy-to-use method of handling iptables rules.
Try using this command to allow a port
sudo ufw allow 1701
To test connectivity, you could try shutting down the VPN software (freeing up the ports) and using netcat to listen, like this:
nc -l 1701
Then use telnet from your Windows host and see what shows up on your Ubuntu terminal. This can be repeated for each port you'd like to test.
How about setting it with JavaScript?
var e = document.getElementById('cardNumber');
e.autocomplete = 'off'; // Maybe should be false
It's not perfect, but your HTML will be valid.
I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following
data class CustomObjectKey(var key1:String = "" , var
key2:String = ""):Comparable<CustomObjectKey?>
{
override fun compareTo(other: CustomObjectKey?): Int {
if(other == null)
return -1
// suppose you want to do comparison based on key 1
return this.key1.compareTo((other)key1)
}
override fun equals(other: Any?): Boolean {
if(other == null)
return false
return this.key1 == (other as CustomObjectKey).key1
}
override fun hashCode(): Int {
return this.key1.hashCode()
}
}
Using jQuery, you can like the map()
method like so;
$.map(arr, function(val,i) {
return parseInt(val);
});
You have to be very careful about the method names. In this case, the method name is just "lowercaseString
", not "lowercaseString:
" (note the absence of the colon). That's why you're getting NO
returned, because NSString
objects respond to the lowercaseString
message but not the lowercaseString:
message.
How do you know when to add a colon? You add a colon to the message name if you would add a colon when calling it, which happens if it takes one argument. If it takes zero arguments (as is the case with lowercaseString
), then there is no colon. If it takes more than one argument, you have to add the extra argument names along with their colons, as in compare:options:range:locale:
.
You can also look at the documentation and note the presence or absence of a trailing colon.

This statement will evaluate true for numbers between 10 and 20.
This is a rough equivalent to 10 < x < 20
what about changing the position: relative on your #content #text div to position: absolute
#content #text {
position:absolute;
width:950px;
height:215px;
color:red;
}
then you can use the css properties left and top to position within the #content div
Datatype: array_name:datatype[]=[];
Example string: users:string[]=[];
For array of objects:
Objecttype: object_name:objecttype[]=[{}];
Example user: Users:user[]=[{}];
And if in some cases it's coming undefined in binding, make sure to initialize it on Oninit()
.
Do this using rs.next()
:
while (rs.next())
{
...
}
If the result set is empty, the code inside the loop won't execute.
In the case that you not only want to exclude a list of special characters, but to exclude all characters that are not letters or numbers, I would suggest that you use a char type comparison approach.
For each character in the String, I would check if the unicode character is between "A" and "Z", between "a" and "z" or between "0" and "9". This is the vba code:
Function cleanString(text As String) As String
Dim output As String
Dim c 'since char type does not exist in vba, we have to use variant type.
For i = 1 To Len(text)
c = Mid(text, i, 1) 'Select the character at the i position
If (c >= "a" And c <= "z") Or (c >= "0" And c <= "9") Or (c >= "A" And c <= "Z") Then
output = output & c 'add the character to your output.
Else
output = output & " " 'add the replacement character (space) to your output
End If
Next
cleanString = output
End Function
The Wikipedia list of Unicode characers is a good quick-start if you want to customize this function a little more.
This solution has the advantage to be functionnal even if the user finds a way to introduce new special characters. It also faster than comparing two lists together.
I haven't played with these settings myself so this is just speculation but if we think about this issue as normal cores and threads in a distributed system then in your cluster you can use up to 12 cores (4 * 3 machines) and 24 threads (8 * 3 machines). In your first two examples you are giving your job a fair number of cores (potential computation space) but the number of threads (jobs) to run on those cores is so limited that you aren't able to use much of the processing power allocated and thus the job is slower even though there is more computation resources allocated.
you mention that your concern was in the shuffle step - while it is nice to limit the overhead in the shuffle step it is generally much more important to utilize the parallelization of the cluster. Think about the extreme case - a single threaded program with zero shuffle.
If you use git stash apply
rather than git stash pop
, it will apply the stash to your working tree but still keep the stash.
With this done, you can add
/commit
the file that you want and then reset the remaining changes.
Here is a simple php script for login and a page that can only be accessed by logged in users.

In the new lodash release v4.0.0 _.pluck
has removed in favor of _.map
Then you can use this:
_.map(users, 'id'); // [12, 14, 16, 18]
You can see in Github Changelog
You are actually ignoring exception in your code. But I suggest you to reconsider.
Here is a quote from Coding Crimes: Ignoring Exceptions
For a start, the exception should be logged at the very least, not just written out to the console. Also, in most cases, the exception should be thrown back to the caller for them to deal with. If it doesn't need to be thrown back to the caller, then the exception should be handled. And some comments would be nice too.
The usual excuse for this type of code is "I didn't have time", but there is a ripple effect when code is left in this state. Chances are that most of this type of code will never get out in the final production. Code reviews or static analysis tools should catch this error pattern. But that's no excuse, all this does is add time to the maintainance and debugging of the software.
Even if you are ignoring it I suggest you to use specific exception names instead of superclass name. ie., Use NullPointerException
instead of Exception
in your catch
clause.
To be able to access the form in your controller, you have to add it to a dummy scope object.
Something like $scope.dummy = {}
For your situation this would mean something like:
<form name="dummy.customerForm">
In your controller you will be able to access the form by:
$scope.dummy.customerForm
and you will be able to do stuff like
$scope.dummy.customerForm.$setPristine()
Having a '.' in your models will ensure that prototypal inheritance is in play. So, use
<input type="text" ng-model="someObj.prop1">
rather than<input type="text" ng-model="prop1">
If you really want/need to use a primitive, there are two workarounds:
1.Use $parent.parentScopeProperty in the child scope. This will prevent the child scope from creating its own property. 2.Define a function on the parent scope, and call it from the child, passing the primitive value up to the parent (not always possible)
or you can also do ( for pem file )
scp -r -i file.pem [email protected]:/home/backup /home/user/Desktop/
I use the filter solution above, for ie8. However.. In order to solve the freezing links problem , do also the following:
background: no-repeat center center fixed\0/; /* IE8 HACK */
This has solved the frozen links problem for me.
This worked for me:
import re
text = 'how are u? umberella u! u. U. U@ U# u '
rex = re.compile(r'\bu\b', re.IGNORECASE)
print(rex.sub('you', text))
It pre-compiles the regular expression and makes use of re.IGNORECASE so that we don't have to worry about case in our regular expression! BTW, I love the funky spelling of umbrella! :-)
Here is the example directly from PEP 8 on limiting line length:
class Rectangle(Blob):
def __init__(self, width, height,
color='black', emphasis=None, highlight=0):
if (width == 0 and height == 0 and
color == 'red' and emphasis == 'strong' or
highlight > 100):
raise ValueError("sorry, you lose")
if width == 0 and height == 0 and (color == 'red' or
emphasis is None):
raise ValueError("I don't think so -- values are %s, %s" %
(width, height))
Blob.__init__(self, width, height,
color, emphasis, highlight)
I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:
.ui-helper-center {
text-align: center;
}
And then add the ui-helper-center
class to the table cells for which you wish to control the alignment:
<td class="ui-helper-center">Content</td>
EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.
See Gabe's answer for how to include the CSS rule into your page.
You want to use "multiline".
$string =~ /(START)(.+?)(END)/m;
button.setVisibility(button.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);
Makes it visible if invisible and invisible if visible
The parent component can manage child state passing a prop to child and the child convert this prop in state using componentWillReceiveProps.
class ParentComponent extends Component {
state = { drawerOpen: false }
toggleChildMenu = () => {
this.setState({ drawerOpen: !this.state.drawerOpen })
}
render() {
return (
<div>
<button onClick={this.toggleChildMenu}>Toggle Menu from Parent</button>
<ChildComponent drawerOpen={this.state.drawerOpen} />
</div>
)
}
}
class ChildComponent extends Component {
constructor(props) {
super(props)
this.state = {
open: false
}
}
componentWillReceiveProps(props) {
this.setState({ open: props.drawerOpen })
}
toggleMenu() {
this.setState({
open: !this.state.open
})
}
render() {
return <Drawer open={this.state.open} />
}
}
As a LinearSegmentedColormaps
is based on a dictionary of red, green and blue, it's necessary to reverse each item:
import matplotlib.pyplot as plt
import matplotlib as mpl
def reverse_colourmap(cmap, name = 'my_cmap_r'):
"""
In:
cmap, name
Out:
my_cmap_r
Explanation:
t[0] goes from 0 to 1
row i: x y0 y1 -> t[0] t[1] t[2]
/
/
row i+1: x y0 y1 -> t[n] t[1] t[2]
so the inverse should do the same:
row i+1: x y1 y0 -> 1-t[0] t[2] t[1]
/
/
row i: x y1 y0 -> 1-t[n] t[2] t[1]
"""
reverse = []
k = []
for key in cmap._segmentdata:
k.append(key)
channel = cmap._segmentdata[key]
data = []
for t in channel:
data.append((1-t[0],t[2],t[1]))
reverse.append(sorted(data))
LinearL = dict(zip(k,reverse))
my_cmap_r = mpl.colors.LinearSegmentedColormap(name, LinearL)
return my_cmap_r
See that it works:
my_cmap
<matplotlib.colors.LinearSegmentedColormap at 0xd5a0518>
my_cmap_r = reverse_colourmap(my_cmap)
fig = plt.figure(figsize=(8, 2))
ax1 = fig.add_axes([0.05, 0.80, 0.9, 0.15])
ax2 = fig.add_axes([0.05, 0.475, 0.9, 0.15])
norm = mpl.colors.Normalize(vmin=0, vmax=1)
cb1 = mpl.colorbar.ColorbarBase(ax1, cmap = my_cmap, norm=norm,orientation='horizontal')
cb2 = mpl.colorbar.ColorbarBase(ax2, cmap = my_cmap_r, norm=norm, orientation='horizontal')
EDIT
I don't get the comment of user3445587. It works fine on the rainbow colormap:
cmap = mpl.cm.jet
cmap_r = reverse_colourmap(cmap)
fig = plt.figure(figsize=(8, 2))
ax1 = fig.add_axes([0.05, 0.80, 0.9, 0.15])
ax2 = fig.add_axes([0.05, 0.475, 0.9, 0.15])
norm = mpl.colors.Normalize(vmin=0, vmax=1)
cb1 = mpl.colorbar.ColorbarBase(ax1, cmap = cmap, norm=norm,orientation='horizontal')
cb2 = mpl.colorbar.ColorbarBase(ax2, cmap = cmap_r, norm=norm, orientation='horizontal')
But it especially works nice for custom declared colormaps, as there is not a default _r
for custom declared colormaps. Following example taken from http://matplotlib.org/examples/pylab_examples/custom_cmap.html:
cdict1 = {'red': ((0.0, 0.0, 0.0),
(0.5, 0.0, 0.1),
(1.0, 1.0, 1.0)),
'green': ((0.0, 0.0, 0.0),
(1.0, 0.0, 0.0)),
'blue': ((0.0, 0.0, 1.0),
(0.5, 0.1, 0.0),
(1.0, 0.0, 0.0))
}
blue_red1 = mpl.colors.LinearSegmentedColormap('BlueRed1', cdict1)
blue_red1_r = reverse_colourmap(blue_red1)
fig = plt.figure(figsize=(8, 2))
ax1 = fig.add_axes([0.05, 0.80, 0.9, 0.15])
ax2 = fig.add_axes([0.05, 0.475, 0.9, 0.15])
norm = mpl.colors.Normalize(vmin=0, vmax=1)
cb1 = mpl.colorbar.ColorbarBase(ax1, cmap = blue_red1, norm=norm,orientation='horizontal')
cb2 = mpl.colorbar.ColorbarBase(ax2, cmap = blue_red1_r, norm=norm, orientation='horizontal')
Using a shebang line to invoke the appropriate interpreter is not just for BASH. You can use the shebang for any interpreted language on your system such as Perl, Python, PHP (CLI) and many others. By the way, the shebang
#!/bin/sh -
(it can also be two dashes, i.e. --
) ends bash options everything after will be treated as filenames and arguments.
Using the env
command makes your script portable and allows you to setup custom environments for your script hence portable scripts should use
#!/usr/bin/env bash
Or for whatever the language such as for Perl
#!/usr/bin/env perl
Be sure to look at the man
pages for bash
:
man bash
and env
:
man env
Note: On Debian and Debian-based systems, like Ubuntu, sh
is linked to dash
not bash
. As all system scripts use sh
. This allows bash to grow and the system to stay stable, according to Debian.
Also, to keep invocation *nix like I never use file extensions on shebang invoked scripts, as you cannot omit the extension on invocation on executables as you can on Windows. The file command can identify it as a script.
Another solution I ran across tonight, which worked for my needs, was to add box-sizing
attributes:
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
These attributes force the border to be part of the box model's width and height and correct the issue as well.
According to caniuse.com » box-sizing, box-sizing
is supported in IE8+.
If you're using LESS or Sass there is a Bootstrap mixin for this.
LESS:
.box-sizing(border-box);
Sass:
@include box-sizing(border-box);
In general, you implement the ICloneable interface and implement Clone yourself. C# objects have a built-in MemberwiseClone method that performs a shallow copy that can help you out for all the primitives.
For a deep copy, there is no way it can know how to automatically do it.
You can nest your queries:
select * from (
select bla
from bla
where bla
order by finaldate desc
)
where rownum < 2
I actually got this error because I was checking InnerHtml for some content that was generated dynamically - i.e. a control that is runat=server.
To solve this I had to remove the "static" keyword on my method, and it ran fine.
