I am working with sdk 23.1.0 and gradle 1.3.1. I created a new project edited nothing and got the aidl error. I went into my project gradle file and changed tool to 22.0.1 instead of 23.1.0 and it worked:
compileSdkVersion 23
buildToolsVersion "22.0.1" //"23.1.0"
To resolve this issue:
The jstl jar
should be in your classpath. If you are using maven, add a dependency to jstl in your pom.xml
using the snippet provided here. If you are not using maven, download the jstl jar from here and deploy it into your WEB-INF/lib
.
Make sure you have the following taglib directive at the top of your jsp
:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
This simplifies it a bit and it behaves as you want it.
FileWriter f = new FileWriter("../playlist/"+existingPlaylist.getText()+".txt");
try {
f.write(source);
...
} catch(...) {
} finally {
//close it here
}
Connection timeouts (assuming a local network and several client machines) typically result from
a) some kind of firewall on the way that simply eats the packets without telling the sender things like "No Route to host"
b) packet loss due to wrong network configuration or line overload
c) too many requests overloading the server
d) a small number of simultaneously available threads/processes on the server which leads to all of them being taken. This happens especially with requests that take a long time to run and may combine with c).
Hope this helps.
In my case, this was because the partition hosting the ibdata1 file was full.
Set showInLegend to false.
series: [{

Just set the position of the div and you may have to set the z-index.
ex.
div#map-div {
position: absolute;
left: 10px;
top: 10px;
}
div#cover-div {
position:absolute;
left:10px;
top: 10px;
z-index:3;
}
There is one way to implement multiple interface.
Just extend one interface from another or create interface that extends predefined interface Ex:
public interface PlnRow_CallBack extends OnDateSetListener {
public void Plan_Removed();
public BaseDB getDB();
}
now we have interface that extends another interface to use in out class just use this new interface who implements two or more interfaces
public class Calculator extends FragmentActivity implements PlnRow_CallBack {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
}
@Override
public void Plan_Removed() {
}
@Override
public BaseDB getDB() {
}
}
hope this helps
Using the latest Luna upgrade. The only solution that worked was Window >> New Window. It's very easy to lose that critical bar.
Here's what I did:
That's it. I have tested it with my Nokia and it's working for me.
For frequent uses of this command I found it easy to add the location of C:\xampp\apache\bin
to the PATH
. Use whatever directory you have this installed in.
Then you can run from any directory in command line:
httpd -k restart
The answer above that suggests httpd -k -restart is actually a typo. You can see the commands by running httpd /?
I met NoClassDefFoundError for a class that exists in my project (not a library class). The class exists but i got NoClassDefFoundError. In my case, the problem was multidex support. The problem and solution is here: Android Multidex and support libraries
You get this error for Android versions lower than 5.0.
In fact when you open the pom.xml, you should see 5 tabs in the bottom. Click the pom.xml, and you can type whatever dependencies you want.
The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS
In computer programming, particularly in the C, C++, and C# programming languages, a variable or object declared with the volatile
keyword usually has special properties related to optimization and/or threading. Generally speaking, the volatile
keyword is intended to prevent the (pseudo)compiler from applying any optimizations on the code that assume values of variables cannot change "on their own." (c) Wikipedia
I find this to be the most straightforward and working:
df = pd.DataFrame({
'one thing':[1,2,3,4],
'second thing':[0.1,0.2,1,2],
'other thing':['a','e','i','o']})
df = df[['one thing','second thing', 'other thing']]
Need to add a single attribute to your toolbar theme -
<style name="toolbar_theme" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="colorControlNormal">@color/arrow_color</item>
</style>
Apply this toolbar_theme to your toolbar.
OR
you can directly apply to your theme -
<style name="CustomTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorControlNormal">@color/arrow_color</item>
//your code ....
</style>
A better solution is explained in the official explanation. I left the answer I have given before under the horizontal line.
According to the solution there:
Use an external tag and write down the following code below in the top-level build.gradle file. You're going to change the version to a variable rather than a static version number.
ext {
compileSdkVersion = 26
supportLibVersion = "27.1.1"
}
Change the static version numbers in your app-level build.gradle file, the one has (Module: app)
near.
android {
compileSdkVersion rootProject.ext.compileSdkVersion // It was 26 for example
// the below lines will stay
}
// here there are some other stuff maybe
dependencies {
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
// the below lines will stay
}
Sync your project and you'll get no errors.
You don't need to add anything to Gradle scripts. Install the necessary SDKs and the problem will be solved.
In your case, install the libraries below from Preferences > Android SDK or Tools > Android > SDK Manager
you could change the innerHtml on an element
function produceMessage(){
var msg= 'Hello<br />';
document.getElementById('someElement').innerHTML = msg;
}

You can access the fields by indexing the object array:
foreach (object[] item in selectedValues)
{
idTextBox.Text = item[0];
titleTextBox.Text = item[1];
contentTextBox.Text = item[2];
}
That said, you'd be better off storing the fields in a small class of your own if the number of items is not dynamic:
public class MyObject
{
public int Id { get; set; }
public string Title { get; set; }
public string Content { get; set; }
}
Then you can do:
foreach (MyObject item in selectedValues)
{
idTextBox.Text = item.Id;
titleTextBox.Text = item.Title;
contentTextBox.Text = item.Content;
}
In [Package Manager Console]
try the below
Install-Package NuGet.CommandLine
for(Field field : cls.getDeclaredFields()){
Class type = field.getType();
String name = field.getName();
Annotation[] annotations = field.getDeclaredAnnotations();

VBA subs are no macros. A VBA sub can be a macro, but it is not a must.
The term "macro" is only used for recorded user actions. from these actions a code is generated and stored in a sub. This code is simple and do not provide powerful structures like loops, for example Do .. until, for .. next, while.. do, and others.
The more elegant way is, to design and write your own VBA code without using the macro features!
VBA is a object based and event oriented language. Subs, or bette call it "sub routines", are started by dedicated events. The event can be the pressing of a button or the opening of a workbook and many many other very specific events.
If you focus to VB6 and not to VBA, then you can state, that there is always a main-window or main form. This form is started if you start the compiled executable "xxxx.exe".
In VBA you have nothing like this, but you have a XLSM file wich is started by Excel. You can attach some code to the Workbook_Open event. This event is generated, if you open your desired excel file which is called a workbook. Inside the workbook you have worksheets.
It is useful to get more familiar with the so called object model of excel. The workbook has several events and methods. Also the worksheet has several events and methods.
In the object based model you have objects, that have events and methods. methods are action you can do with a object. events are things that can happen to an object. An objects can contain another objects, and so on. You can create new objects, like sheets or charts.
The simple way would be to disable the foreign key check; make the changes then re-enable foreign key check.
SET FOREIGN_KEY_CHECKS=0; -- to disable them
SET FOREIGN_KEY_CHECKS=1; -- to re-enable them
I suggest storing the numbers in a varchar without formatting. Then you can just reformat the numbers on the client side appropriately. Some cultures prefer to have phone numbers written differently; in France, they write phone numbers like 01-22-33-44-55.
You might also consider storing another field for the country that the phone number is for, because this can be difficult to figure out based on the number you are looking at. The UK uses 11 digit long numbers, some African countries use 7 digit long numbers.
That said, I used to work for a UK phone company, and we stored phone numbers in our database based on if they were UK or international. So, a UK phone number would be 02081234123 and an international one would be 001800300300.

Screen-shot of how it does NOT conflict with search: Notes:
An addendum to this. You can use character entities (such as changing <div>
to <div>
) and it will render in the textarea. But when it is saved, the value of the textarea is the text as rendered. So you don't need to de-encode. I just tested this across browsers (ie back to 11).

I was facing this issue while deploying a django app on heroku.
In my case the requirements.txt, Procfile and runtime.txt files were present in a subdirectory. Moving them to the root directory of the repository solved the problem.
Heroku is specifically looking for requirements.txt in the root directory to setup the python environment.
P.S :
If heroku is unable to reach till the wsgi file residing in the subdirectory, solve it by referring below thread -
How can I modify Procfile to run Gunicorn process in a non-standard folder on Heroku?

You can also do the following:
txt = "Hello World!"
print (*txt, sep='\n')
This does not use loops but internally print statement takes care of it.
*
unpacks the string into a list and sends it to the print statement
sep='\n'
will ensure that the next char is printed on a new line
The output will be:
H
e
l
l
o
W
o
r
l
d
!
If you do need a loop statement, then as others have mentioned, you can use a for loop like this:
for x in txt: print (x)
You should define a key name while storing data to local storage which should be a string and value should be a string
localStorage.setItem('dataSource', this.dataSource.length);
and to print, you should use getItem
console.log(localStorage.getItem('dataSource'));
Or with Prototype:
Event.observe(this, 'load', function() { new Ajax.Request(... ) );
Or better, define the function elsewhere rather than inline, then:
Event.observe(this, 'load', functionName );
You don't have to use jQuery or Prototype specifically, but I hope you're using some kind of library. Either library is going to handle the event handling in a more consistent manner than onload, and of course is going to make it much easier to process the Ajax call. If you must use the body onload attribute, then you should just be able to call the same function as referenced in these examples (onload="javascript:functionName();"
).
However, if your database update doesn't depend on the rendering on the page, why wait until it's fully loaded? You could just include a call to the Ajax-calling function at the end of the JavaScript on the page, which should give nearly the same effect.
I tested and the script run ok!

Any mature enough SQL database should be able to execute that just as effectively as the equivalent JOIN
. Use whatever is more readable to you.
You have to explicitly define the constructor in B and explicitly call the constructor for the parent.
B(int x) : A(x) { }
or
B() : A(5) { }
You will use props in your child component
for example
if your now component props is
{
booking: 4,
isDisable: false
}
you can use this props in your child compoenet
<div {...this.props}> ... </div>
in you child component, you will receive all your parent props.
You may use str.isdigit()
and str.isalpha()
to check whether given string is positive integer and alphabet respectively.
Sample Results:
# For alphabet
>>> 'A'.isdigit()
False
>>> 'A'.isalpha()
True
# For digit
>>> '1'.isdigit()
True
>>> '1'.isalpha()
False
str.isdigit()
returns False
if the string is a negative number or a float number. For example:
# returns `False` for float
>>> '123.3'.isdigit()
False
# returns `False` for negative number
>>> '-123'.isdigit()
False
If you want to also check for the negative integers and float
, then you may write a custom function to check for it as:
def is_number(n):
try:
float(n) # Type-casting the string to `float`.
# If string is not a valid `float`,
# it'll raise `ValueError` exception
except ValueError:
return False
return True
Sample Run:
>>> is_number('123') # positive integer number
True
>>> is_number('123.4') # positive float number
True
>>> is_number('-123') # negative integer number
True
>>> is_number('-123.4') # negative `float` number
True
>>> is_number('abc') # `False` for "some random" string
False
The above functions will return True
for the "NAN" (Not a number) string because for Python it is valid float representing it is not a number. For example:
>>> is_number('NaN')
True
In order to check whether the number is "NaN", you may use math.isnan()
as:
>>> import math
>>> nan_num = float('nan')
>>> math.isnan(nan_num)
True
Or if you don't want to import additional library to check this, then you may simply check it via comparing it with itself using ==
. Python returns False
when nan
float is compared with itself. For example:
# `nan_num` variable is taken from above example
>>> nan_num == nan_num
False
Hence, above function is_number
can be updated to return False
for "NaN"
as:
def is_number(n):
is_number = True
try:
num = float(n)
# check for "nan" floats
is_number = num == num # or use `math.isnan(num)`
except ValueError:
is_number = False
return is_number
Sample Run:
>>> is_number('Nan') # not a number "Nan" string
False
>>> is_number('nan') # not a number string "nan" with all lower cased
False
>>> is_number('123') # positive integer
True
>>> is_number('-123') # negative integer
True
>>> is_number('-1.12') # negative `float`
True
>>> is_number('abc') # "some random" string
False
The above function will still return you False
for the complex numbers. If you want your is_number
function to treat complex numbers as valid number, then you need to type cast your passed string to complex()
instead of float()
. Then your is_number
function will look like:
def is_number(n):
is_number = True
try:
# v type-casting the number here as `complex`, instead of `float`
num = complex(n)
is_number = num == num
except ValueError:
is_number = False
return is_number
Sample Run:
>>> is_number('1+2j') # Valid
True # : complex number
>>> is_number('1+ 2j') # Invalid
False # : string with space in complex number represetantion
# is treated as invalid complex number
>>> is_number('123') # Valid
True # : positive integer
>>> is_number('-123') # Valid
True # : negative integer
>>> is_number('abc') # Invalid
False # : some random string, not a valid number
>>> is_number('nan') # Invalid
False # : not a number "nan" string
PS: Each operation for each check depending on the type of number comes with additional overhead. Choose the version of is_number
function which fits your requirement.

Let's say I have 32-bit ARGB value with 8-bits per channel. I want to replace the alpha component with another alpha value, such as 0x45
unsigned long alpha = 0x45
unsigned long pixel = 0x12345678;
pixel = ((pixel & 0x00FFFFFF) | (alpha << 24));
The mask turns the top 8 bits to 0, where the old alpha value was. The alpha value is shifted up to the final bit positions it will take, then it is OR-ed into the masked pixel value. The final result is 0x45345678 which is stored into pixel.
You're probably passing null
value if you're loading the coordinates dynamically, set a check before you call the map loader ie: if(mapCords){loadMap}

I have personally witnessed "" resulting in (minor) problems twice. Once was due to a mistake of a junior developer new to team-based programming, and the other was a simple typo, but the fact is using string.Empty would have avoided both issues.
Yes, this is very much a judgement call, but when a language gives you multiple ways to do things, I tend to lean toward the one that has the most compiler oversight and strongest compile-time enforcement. That is not "". It's all about expressing specific intent.
If you type string.EMpty or Strng.Empty, the compiler lets you know you did it wrong. Immediately. It simply will not compile. As a developer you are citing specific intent that the compiler (or another developer) cannot in any way misinterpret, and when you do it wrong, you can't create a bug.
If you type " " when you mean "" or vice-versa, the compiler happily does what you told it to do. Another developer may or may not be able to glean your specific intent. Bug created.
Long before string.Empty was a thing I've used a standard library that defined the EMPTY_STRING constant. We still use that constant in case statements where string.Empty is not allowed.
Whenever possible, put the compiler to work for you, and eliminate the possibility of human error, no matter how small. IMO, this trumps "readability" as others have cited.
Specificity and compile time enforcement. It's what's for dinner.

The only thing that worked for me and I think it is the simplest way is using a Path with a paint object like this:
Paint paintDash = new Paint();
paintDash.setARGB(255, 0, 0, 0);
paintDash.setStyle(Paint.Style.STROKE);
paintDash.setPathEffect(new DashPathEffect(new float[]{10f,10f}, 0));
paintDash.setStrokeWidth(2);
Path pathDashLine = new Path();
Then onDraw(): (important call reset if you change those points between ondraw calls, cause Path save all the movements)
pathDashLine.reset();
pathDashLine.moveTo(porigenX, porigenY);
pathDashLine.lineTo(cursorX,cursorY);
c.drawPath(pathDashLine, paintDash);
I resolved the issue by converting the source feed from http://www.news18.com/rss/politics.xml to https://www.news18.com/rss/politics.xml
with http below code was creating an empty file which was causing the issue down the line
String feedUrl = "https://www.news18.com/rss/politics.xml";
File feedXmlFile = null;
try {
feedXmlFile =new File("C://opinionpoll/newsFeed.xml");
FileUtils.copyURLToFile(new URL(feedUrl),feedXmlFile);
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(feedXmlFile);
Hopefully I'm understanding your question correctly in that you are wondering about the differences between dispatch_async and dispatch_sync?
dispatch_async
will dispatch the block to a queue asynchronously. Meaning it will send the block to the queue and not wait for it to return before continuing on the execution of the remaining code in your method.
dispatch_sync
will dispatch the block to a queue synchronously. This will prevent any more execution of remaining code in the method until the block has finished executing.
I've mostly used a dispatch_async
to a background queue to get work off the main queue and take advantage of any extra cores that the device may have. Then dispatch_async
to the main thread if I need to update the UI.
Good luck
A simple way but dangerous way to do this would be to use eval()
. eval()
executes the string passed to it as code. The dangerous thing about this is that if this string is gained from user input, they could maliciously execute code that could break the computer. I would get the input, check it with a regex, and then execute it if you determine if it's OK. If it's only going to be in the format "number operation number", then you could use a simple regex:
import re
s = raw_input('What is your math problem? ')
if re.findall('\d+? *?\+ *?\d+?', s):
print eval(s)
else:
print "Try entering a math problem"
Otherwise, you would have to come up with something a bit stricter than this. You could also do it conversely, using a regex to find if certain things are not in it, such as numbers and operations. Also you could check to see if the input contains certain commands.

There is one space after the IFS.
It's looking for the file in the current directory.
First, go to that directory
cd /users/gcameron/Desktop/map

Update 2018-01-07 with Spring Boot 1.5.8.RELEASE
If you want to know how to config it, how to use it, and how to control transaction. I may have answers for you.
You can see the runnable example and some explanation in https://www.surasint.com/spring-boot-with-multiple-databases-example/
I copied some code here.
First you have to set application.properties like this
#Database
database1.datasource.url=jdbc:mysql://localhost/testdb
database1.datasource.username=root
database1.datasource.password=root
database1.datasource.driver-class-name=com.mysql.jdbc.Driver
database2.datasource.url=jdbc:mysql://localhost/testdb2
database2.datasource.username=root
database2.datasource.password=root
database2.datasource.driver-class-name=com.mysql.jdbc.Driver
Then define them as providers (@Bean) like this:
@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
return DataSourceBuilder.create().build();
}
@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
return DataSourceBuilder.create().build();
}
Note that I have @Bean(name="datasource1") and @Bean(name="datasource2"), then you can use it when we need datasource as @Qualifier("datasource1") and @Qualifier("datasource2") , for example
@Qualifier("datasource1")
@Autowired
private DataSource dataSource;
If you do care about transaction, you have to define DataSourceTransactionManager for both of them, like this:
@Bean(name="tm1")
@Autowired
@Primary
DataSourceTransactionManager tm1(@Qualifier ("datasource1") DataSource datasource) {
DataSourceTransactionManager txm = new DataSourceTransactionManager(datasource);
return txm;
}
@Bean(name="tm2")
@Autowired
DataSourceTransactionManager tm2(@Qualifier ("datasource2") DataSource datasource) {
DataSourceTransactionManager txm = new DataSourceTransactionManager(datasource);
return txm;
}
Then you can use it like
@Transactional //this will use the first datasource because it is @primary
or
@Transactional("tm2")
This should be enough. See example and detail in the link above.
Some cron implementations support the "L" flag to represent the last day of the month.
If you're lucky to be using one of those implementations, it's as simple as:
0 55 23 L * ?
That will run at 11:55 pm on the last day of every month.

As of V8 v7.0 / Chrome 70, V8 uses TimSort, Python's sorting algorithm. Chrome 70 was released on September 13, 2018.
See the the post on the V8 dev blog for details about this change. You can also read the source code or patch 1186801.
I am working with a Python code for a REST API, so this is for those who are working on similar projects.
I extract data from an URL using a POST request and the raw output is JSON. For some reason the output is already a dictionary, not a list, and I'm able to refer to the nested dictionary keys right away, like this:
datapoint_1 = json1_data['datapoints']['datapoint_1']
where datapoint_1 is inside the datapoints dictionary.
you can creat HttpClient instance by the way with Httpclient-android-4.3.5,it can work well.
SSLContext sslContext = SSLContexts.createSystemDefault();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
sslContext,
SSLConnectionSocketFactory.STRICT_HOSTNAME_VERIFIER);
RequestConfig.Builder requestConfigBuilder = RequestConfig.custom().setCircularRedirectsAllowed(false).setConnectionRequestTimeout(30*1000).setConnectTimeout(30 * 1000).setMaxRedirects(10).setSocketTimeout(60 * 1000);
CloseableHttpClient hc = HttpClients.custom().setSSLSocketFactory(sslsf).setDefaultRequestConfig(requestConfigBuilder.build()).build();
Currently from MySQL 8
you can set the following to a DATE
column:
In MySQL Workbench
, in the Default
field next to the column, write: (curdate())
If you put just curdate()
it will fail. You need the extra (
and )
at the beginning and end.
iris %>% dplyr::select(where(is.numeric)) #as per most recent updates
Another option with purrr
would be to negate discard
function:
iris %>% purrr::discard(~!is.numeric(.))
If you want the names of the numeric columns, you can add names
or colnames
:
iris %>% purrr::discard(~!is.numeric(.)) %>% names
Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.
Server side Comments:
Razor .cshtml
@* Comment goes here *@
.aspx
For those looking for the older .aspx
view (and Asp.Net WebForms) server side comment syntax:
<%-- Comment goes here --%>
Client Side Comments
HTML Comment
<!-- Comment goes here -->
Javascript Comment
// One line Comment goes Here
/* Multiline comment
goes here */
As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).
On your remote machine, System.Data.OracleClient need access to some of the oracle dll which are not part of .Net. Solutions:
On your local machine most probably path to Oracle Client is already added in Path environment variable to there required dll are available to application but not on remote machine
This following code example seems to work best for me. While you can use 'return false' that stops all handling of that event for the div or any of it's children. If you want to have controls on the pop-up div (a pop-up login form for example) you need to use event.stopPropogation().
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<a id="link" href="#">show box</a>
<div id="box" style="background: #eee; display: none">
<p>a paragraph of text</p>
<input type="file" />
</div>
<script src="jquery.js" type="text/javascript"></script>
<script type="text/javascript">
var box = $('#box');
var link = $('#link');
link.click(function() {
box.show(); return false;
});
$(document).click(function() {
box.hide();
});
box.click(function(e) {
e.stopPropagation();
});
</script>
</body>
</html>
I navigated to:
Eclipse>Pref>Java>Installed JRE>Search...
2 of them popped up and I checked the latest one. Before I did this I also went to About>Check for Updates
and updated it. I didn't have to reinstall any JRE or JDK either. I might have done it a while back, except it was with 1.6 not 1.4. Hope that helps!
If your <td>
is not empty, one popular trick is to insert a non breaking space
in it, such that:
<td id="td1"> </td>
Then you will be able to use:
document.getElementById('td1').firstChild.data = 'New Value';
Otherwise, if you do not fancy adding the meaningless  
you can use the solution that Jonathan Fingland described in the other answer.
I ran into this with a bitbucket account, where I had accidentally stored ginormous *.jpa backups of my site.
git filter-branch --prune-empty --index-filter 'git rm -rf --cached --ignore-unmatch MY-BIG-DIRECTORY-OR-FILE' --tag-name-filter cat -- --all
Relpace MY-BIG-DIRECTORY
with the folder in question to completely rewrite your history (including tags).
This works on SQL Server 2000.
use master
select count(*) From sysxlogins WHERE NAME = 'myUsername'
on SQL 2005, change the 2nd line to
select count(*) From syslogins WHERE NAME = 'myUsername'
I'm not sure about SQL 2008, but I'm guessing that it will be the same as SQL 2005 and if not, this should give you an idea of where t start looking.
Another way of dealing with this situation if your files ARE already checked in, and your files have been merged (but not committed, so the merge conflicts are inserted into the file) is to run:
git reset
This will switch to HEAD, and tell git to forget any merge conflicts, and leave the working directory as is. Then you can edit the files in question (search for the "Updated upstream" notices). Once you've dealt with the conflicts, you can run
git add -p
which will allow you to interactively select which changes you want to add to the index. Once the index looks good (git diff --cached
), you can commit, and then
git reset --hard
to destroy all the unwanted changes in your working directory.
This is a function i used in the past for substracting a date from another one related with your question, my principe was to get how many days, hours minutes and seconds has left until a product has expired :
$expirationDate = strtotime("2015-01-12 20:08:23");
$toDay = strtotime(date('Y-m-d H:i:s'));
$difference = abs($toDay - $expirationDate);
$days = floor($difference / 86400);
$hours = floor(($difference - $days * 86400) / 3600);
$minutes = floor(($difference - $days * 86400 - $hours * 3600) / 60);
$seconds = floor($difference - $days * 86400 - $hours * 3600 - $minutes * 60);
echo "{$days} days {$hours} hours {$minutes} minutes {$seconds} seconds";
The accepted answer here indeed makes a json from a form, but the json contents is really a string with url-encoded contents.
To make a more realistic json POST, use some solution from Serialize form data to JSON to make formToJson
function and add contentType: 'application/json;charset=UTF-8'
to the jQuery ajax call parameters.
$.ajax({
url: 'test.php',
type: "POST",
dataType: 'json',
data: formToJson($("form")),
contentType: 'application/json;charset=UTF-8',
...
})
I prefer to use Daniel X. Moore's {SUPER: SYSTEM}
. This is a discipline that provides benefits such as true instance variables, trait based inheritance, class hierarchies and configuration options. The example below illustrates the use of true instance variables, which I believe is the biggest advantage. If you don't need instance variables and are happy with only public or private variables then there are probably simpler systems.
function Person(I) {
I = I || {};
Object.reverseMerge(I, {
name: "McLovin",
age: 25,
homeState: "Hawaii"
});
return {
introduce: function() {
return "Hi I'm " + I.name + " and I'm " + I.age;
}
};
}
var fogel = Person({
age: "old enough"
});
fogel.introduce(); // "Hi I'm McLovin and I'm old enough"
Wow, that's not really very useful on it's own, but take a look at adding a subclass:
function Ninja(I) {
I = I || {};
Object.reverseMerge(I, {
belt: "black"
});
// Ninja is a subclass of person
return Object.extend(Person(I), {
greetChallenger: function() {
return "In all my " + I.age + " years as a ninja, I've never met a challenger as worthy as you...";
}
});
}
var resig = Ninja({name: "John Resig"});
resig.introduce(); // "Hi I'm John Resig and I'm 25"
Another advantage is the ability to have modules and trait based inheritance.
// The Bindable module
function Bindable() {
var eventCallbacks = {};
return {
bind: function(event, callback) {
eventCallbacks[event] = eventCallbacks[event] || [];
eventCallbacks[event].push(callback);
},
trigger: function(event) {
var callbacks = eventCallbacks[event];
if(callbacks && callbacks.length) {
var self = this;
callbacks.forEach(function(callback) {
callback(self);
});
}
},
};
}
An example of having the person class include the bindable module.
function Person(I) {
I = I || {};
Object.reverseMerge(I, {
name: "McLovin",
age: 25,
homeState: "Hawaii"
});
var self = {
introduce: function() {
return "Hi I'm " + I.name + " and I'm " + I.age;
}
};
// Including the Bindable module
Object.extend(self, Bindable());
return self;
}
var person = Person();
person.bind("eat", function() {
alert(person.introduce() + " and I'm eating!");
});
person.trigger("eat"); // Blasts the alert!
Disclosure: I am Daniel X. Moore and this is my {SUPER: SYSTEM}
. It is the best way to define a class in JavaScript.
One thing you might consider is something like Robocode, in which a lot of coding is abstracted away and you basically just tell a robot what to do. A simple 10-line function can make the robot do a great deal, and has a very visual and easy-to-follow result.
Perhaps Robocode itself isn't suited to the task, but this kind of thing is a good way to relate written code to visual actions on the computer, plus it's fun to watch for when you need to give examples.
public class MyFirstJuniorRobot extends JuniorRobot {
public void run() {
setColors(green, black, blue);
// Seesaw forever
while (true) {
ahead(100); // Move ahead 100
turnGunRight(360); // Spin gun around
back(100); // Move back 100
turnGunRight(360); // Spin gun around
}
}
public void onScannedRobot() {
turnGunTo(scannedAngle);
fire(1);
}
public void onHitByBullet() {
turnAheadLeft(100, 90 - hitByBulletBearing);
}
}
If you want to modify the original array instead of returning a new array, use .push()
...
array1.push.apply(array1, array2);
array1.push.apply(array1, array3);
I used .apply
to push the individual members of arrays 2
and 3
at once.
or...
array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.
for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
array1.push.apply(array1, to_add.slice(n, n+300));
}
If you do this a lot, create a method or function to handle it.
var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);
Object.defineProperty(Array.prototype, "pushArrayMembers", {
value: function() {
for (var i = 0; i < arguments.length; i++) {
var to_add = arguments[i];
for (var n = 0; n < to_add.length; n+=300) {
push_apply(this, slice_call(to_add, n, n+300));
}
}
}
});
and use it like this:
array1.pushArrayMembers(array2, array3);
var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
value: function() {_x000D_
for (var i = 0; i < arguments.length; i++) {_x000D_
var to_add = arguments[i];_x000D_
for (var n = 0; n < to_add.length; n+=300) {_x000D_
push_apply(this, slice_call(to_add, n, n+300));_x000D_
}_x000D_
}_x000D_
}_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);
_x000D_
SELECT unnest(ARRAY[1,2,2,3,3])
EXCEPT
SELECT unnest(ARRAY[1,1,2,3,3])
UNION
SELECT unnest(ARRAY[1,1,2,3,3])
EXCEPT
SELECT unnest(ARRAY[1,2,2,3,3])
Result is null, but sources are different!
But:
(
SELECT unnest(ARRAY[1,2,2,3])
EXCEPT ALL
SELECT unnest(ARRAY[2,1,2,3])
)
UNION
(
SELECT unnest(ARRAY[2,1,2,3])
EXCEPT ALL
SELECT unnest(ARRAY[1,2,2,3])
)
works.
I had the same issue and I realized that my <button>
had a type="submit"
when Bootstrap states that it needs to be type="button"
If you're escaping for HTML, there are only three that I can think of that would be really necessary:
html.replace(/&/g, "&").replace(/</g, "<").replace(/>/g, ">");
Depending on your use case, you might also need to do things like "
to "
. If the list got big enough, I'd just use an array:
var escaped = html;
var findReplace = [[/&/g, "&"], [/</g, "<"], [/>/g, ">"], [/"/g, """]]
for(var item in findReplace)
escaped = escaped.replace(findReplace[item][0], findReplace[item][1]);
encodeURIComponent()
will only escape it for URLs, not for HTML.
You should have a look at moment
which is a python port of the excellent js lib momentjs
.
One advantage of it is the support of ISO 8601
strings formats, as well as a generic "% format" :
import moment
time_string='2012-10-09T19:00:55Z'
m = moment.date(time_string, '%Y-%m-%dT%H:%M:%SZ')
print m.format('YYYY-M-D H:M')
print m.weekday
Result:
2012-10-09 19:10

Most documentation and tutorials use Python's Threading
and Queue
module, and they could seem overwhelming for beginners.
Perhaps consider the concurrent.futures.ThreadPoolExecutor
module of Python 3.
Combined with with
clause and list comprehension it could be a real charm.
from concurrent.futures import ThreadPoolExecutor, as_completed
def get_url(url):
# Your actual program here. Using threading.Lock() if necessary
return ""
# List of URLs to fetch
urls = ["url1", "url2"]
with ThreadPoolExecutor(max_workers = 5) as executor:
# Create threads
futures = {executor.submit(get_url, url) for url in urls}
# as_completed() gives you the threads once finished
for f in as_completed(futures):
# Get the results
rs = f.result()
In excel 2013 the object creation string is:
Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
instead of the code in the answer above:
Dim fs,fname
Set fs=Server.CreateObject("Scripting.FileSystemObject")
Here is how its done in Angular 6
<li *ngFor="let user of userObservable ; first as isFirst">
<span *ngIf="isFirst">default</span>
</li>
Note the change from let first = first
to first as isFirst
substring().

To loop through an object array or just array in javascript, you can do the following:
var cars = [{name: 'Audi'}, {name: 'BMW'}, {name: 'Ferrari'}, {name: 'Mercedes'}, {name: 'Maserati'}];
for(var i = 0; i < cars.length; i++) {
console.log(cars[i].name);
}
There is also the forEach() function, which is more "javascript-ish" and also less code but more complicated for its syntax:
cars.forEach(function (car) {
console.log(car.name);
});
And both of them are outputting the following:
// Audi
// BMW
// Ferrari
// Mercedes
// Maserati
From what I understand, you struggle with what to put into your template.
I'll show an example:
<ul>
{% for guest in guests %}
<li>{{ guest.name }} <a href="{{ path('your_delete_route_name',{'id': guest.id}) }}">[[DELETE]]</a></li>
{% endfor %}
</ul>
Now what happens is it iterates over every object within guests (you'll have to rename this if your object collection is named otherwise!), shows the name and places the correct link. The route name might be different.
Using scanf
removing any blank spaces before the string is typed and limiting the amount of characters to be read:
#define SIZE 100
....
char str[SIZE];
scanf(" %99[^\n]", str);
/* Or even you can do it like this */
scanf(" %99[a-zA-Z0-9 ]", str);
If you do not limit the amount of characters to be read with scanf
it can be as dangerous as gets
The Problem might be from the driver name for example instead of DRIVER={MySQL ODBC 5.3 Driver}
try DRIVER={MySQL ODBC 5.3 Unicode Driver}
you can see the name of the driver from administration tool
I try to avoid a few things when using Git.
Using knowledge of the internals, e.g. refs/tags. I try to use solely the documented Git commands and avoid using things which require knowledge of the internal contents of the .git directory. (That is to say, I treat Git as a Git user and not a Git developer.)
The use of force when not required.
Overdoing things. (Pushing a branch and/or lots of tags, to get one tag where I want it.)
So here is my non-violent solution for changing a tag, both locally and remotely, without knowledge of the Git internals.
I use it when a software fix ultimately has a problem and needs to be updated/re-released.
git tag -d fix123 # delete the old local tag
git push github :fix123 # delete the old remote tag (use for each affected remote)
git tag fix123 790a621265 # create a new local tag
git push github fix123 # push new tag to remote (use for each affected remote)
github
is a sample remote name, fix123
is a sample tag name, and 790a621265
a sample commit.
i'd suggest adding a class to display/hide elements:
.hide { display:none; }
and then use jquery's .toggleClass() to show/hide the element:
$(".news").toggleClass("hide");
For example:
Map<Object,Pair<Integer,String>> multiMap = new HashMap<Object,Pair<Integer,String>>();
where the Pair
is a parametric class
public class Pair<A, B> {
A first = null;
B second = null;
Pair(A first, B second) {
this.first = first;
this.second = second;
}
public A getFirst() {
return first;
}
public void setFirst(A first) {
this.first = first;
}
public B getSecond() {
return second;
}
public void setSecond(B second) {
this.second = second;
}
}
The way of dknaack does not work for me, I found this solution as well:
@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList,
"Select chapter", new { @onchange = "location = this.value;" })
where
@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)
In the controller you can add:
DbModel db = new DbModel(); //entity model of Entity Framework
ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");
Instead of window
use global
it('correct url is called', () => {
global.open = jest.fn();
statementService.openStatementsReport(111);
expect(global.open).toBeCalled();
});
you could also try
const open = jest.fn()
Object.defineProperty(window, 'open', open);
The documentation is misleading.
I have the following code running in production
DECLARE @table TABLE (UserID varchar(100))
DECLARE @sql varchar(1000)
SET @sql = 'spSelUserIDList'
/* Will also work
SET @sql = 'SELECT UserID FROM UserTable'
*/
INSERT INTO @table
EXEC(@sql)
SELECT * FROM @table
The regular expression would be:
.+name="([^"]+)"
Then the grouping would be in the \1
You can also use chr(176)
to print the degree sign.
Here is an example using python 3.6.5 interactive shell:
You could unregister the control with
regsvr32 /u badboy.ocx
at the command line. Though i would suggest testing these things in a vmware.
Though not extremely performant, the only readable solution is:
// Split by separator and pick the first one.
// This has all the characters till null, excluding null itself.
retByteArray := bytes.Split(byteArray[:], []byte{0}) [0]
// OR
// If you want a true C-like string, including the null character
retByteArray := bytes.SplitAfter(byteArray[:], []byte{0}) [0]
A full example to have a C-style byte array:
package main
import (
"bytes"
"fmt"
)
func main() {
var byteArray = [6]byte{97,98,0,100,0,99}
cStyleString := bytes.SplitAfter(byteArray[:], []byte{0}) [0]
fmt.Println(cStyleString)
}
A full example to have a Go style string excluding the nulls:
package main
import (
"bytes"
"fmt"
)
func main() {
var byteArray = [6]byte{97, 98, 0, 100, 0, 99}
goStyleString := string(bytes.Split(byteArray[:], []byte{0}) [0])
fmt.Println(goStyleString)
}
This allocates a slice of slice of bytes. So keep an eye on performance if it is used heavily or repeatedly.
If a GPU device has, for example, 4 multiprocessing units, and they can run 768 threads each: then at a given moment no more than 4*768 threads will be really running in parallel (if you planned more threads, they will be waiting their turn).
threads are organized in blocks. A block is executed by a multiprocessing unit. The threads of a block can be indentified (indexed) using 1Dimension(x), 2Dimensions (x,y) or 3Dim indexes (x,y,z) but in any case xyz <= 768 for our example (other restrictions apply to x,y,z, see the guide and your device capability).
Obviously, if you need more than those 4*768 threads you need more than 4 blocks. Blocks may be also indexed 1D, 2D or 3D. There is a queue of blocks waiting to enter the GPU (because, in our example, the GPU has 4 multiprocessors and only 4 blocks are being executed simultaneously).
Suppose we want one thread to process one pixel (i,j).
We can use blocks of 64 threads each. Then we need 512*512/64 = 4096 blocks (so to have 512x512 threads = 4096*64)
It's common to organize (to make indexing the image easier) the threads in 2D blocks having blockDim = 8 x 8 (the 64 threads per block). I prefer to call it threadsPerBlock.
dim3 threadsPerBlock(8, 8); // 64 threads
and 2D gridDim = 64 x 64 blocks (the 4096 blocks needed). I prefer to call it numBlocks.
dim3 numBlocks(imageWidth/threadsPerBlock.x, /* for instance 512/8 = 64*/
imageHeight/threadsPerBlock.y);
The kernel is launched like this:
myKernel <<<numBlocks,threadsPerBlock>>>( /* params for the kernel function */ );
Finally: there will be something like "a queue of 4096 blocks", where a block is waiting to be assigned one of the multiprocessors of the GPU to get its 64 threads executed.
In the kernel the pixel (i,j) to be processed by a thread is calculated this way:
uint i = (blockIdx.x * blockDim.x) + threadIdx.x;
uint j = (blockIdx.y * blockDim.y) + threadIdx.y;
module.exports
and exports
both point to the same object before the module is evaluated.
Any property you add to the module.exports
object will be available when your module is used in another module using require
statement. exports
is a shortcut made available for the same thing. For instance:
module.exports.add = (a, b) => a+b
is equivalent to writing:
exports.add = (a, b) => a+b
So it is okay as long as you do not assign a new value to exports
variable. When you do something like this:
exports = (a, b) => a+b
as you are assigning a new value to exports
it no longer has reference to the exported object and thus will remain local to your module.
If you are planning to assign a new value to module.exports
rather than adding new properties to the initial object made available, you should probably consider doing as given below:
module.exports = exports = (a, b) => a+b

In Swift 3.0, you could use this code below:
let textLabel = UILabel(frame: CGRect(x:containerView.frame.width/2 - 35, y:
containerView.frame.height/2 + 10, width: 70, height: 20))
textLabel.text = "Add Text"
textLabel.font = UIFont(name: "Helvetica", size: 15.0) // set fontName and Size
textLabel.textAlignment = .center
containerView.addSubview(textLabel) // containerView is a UIView

I had problems installing some Wordpress plugins on my local server running php56 on OSX10.11. They failed connection on the external API over SSL.
Installing openSSL didn't solved my problem. But then I figured out that CURL also needed to be reinstalled.
This solved my problem using Homebrew.
brew rm curl && brew install curl --with-openssl
brew uninstall php56 && brew install php56 --with-homebrew-curl --with-openssl

You can try the some thing like the below LINQ snippet.
string[] allLines = File.ReadAllLines(@"E:\Temp\data.csv");
var query = from line in allLines
let data = line.Split(',')
select new
{
Device = data[0],
SignalStrength = data[1],
Location = data[2],
Time = data[3],
Age = Convert.ToInt16(data[4])
};
UPDATE: Over a period of time, things evolved. As of now, I would prefer to use this library http://www.aspnetperformance.com/post/LINQ-to-CSV-library.aspx
In terminal go to which might be different in your PC :
C:\Program Files\Java\jre1.8.0_241\bin
Then:
For Windows:
keytool -list -v -keystore C:\Users\YOURUSERPROFILENAME\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android
For Mac:
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
I fail to see the problem with document.write
. If you are using it before the onload
event fires, as you presumably are, to build elements from structured data for instance, it is the appropriate tool to use. There is no performance advantage to using insertAdjacentHTML
or explicitly adding nodes to the DOM after it has been built. I just tested it three different ways with an old script I once used to schedule incoming modem calls for a 24/7 service on a bank of 4 modems.
By the time it is finished this script creates over 3000 DOM nodes, mostly table cells. On a 7 year old PC running Firefox on Vista, this little exercise takes less than 2 seconds using document.write
from a local 12kb source file and three 1px GIFs which are re-used about 2000 times. The page just pops into existence fully formed, ready to handle events.
Using insertAdjacentHTML
is not a direct substitute as the browser closes tags which the script requires remain open, and takes twice as long to ultimately create a mangled page. Writing all the pieces to a string and then passing it to insertAdjacentHTML
takes even longer, but at least you get the page as designed. Other options (like manually re-building the DOM one node at a time) are so ridiculous that I'm not even going there.
Sometimes document.write
is the thing to use. The fact that it is one of the oldest methods in JavaScript is not a point against it, but a point in its favor - it is highly optimized code which does exactly what it was intended to do and has been doing since its inception.
It's nice to know that there are alternative post-load methods available, but it must be understood that these are intended for a different purpose entirely; namely modifying the DOM after it has been created and memory allocated to it. It is inherently more resource-intensive to use these methods if your script is intended to write the HTML from which the browser creates the DOM in the first place.
Just write it and let the browser and interpreter do the work. That's what they are there for.
PS: I just tested using an onload
param in the body
tag and even at this point the document is still open
and document.write()
functions as intended. Also, there is no perceivable performance difference between the various methods in the latest version of Firefox. Of course there is a ton of caching probably going on somewhere in the hardware/software stack, but that's the point really - let the machine do the work. It may make a difference on a cheap smartphone though. Cheers!
tl;dr
cp -R "/src/project 1/App" "/src/project 2"
Explanation:
Using quotes will cater for spaces in the directory names
cp -R "/src/project 1/App" "/src/project 2"
If the App directory is specified in the destination directory:
cp -R "/src/project 1/App" "/src/project 2/App"
and "/src/project 2/App" already exists the result will be "/src/project 2/App/App"
Best not to specify the directory copied in the destination so that the command can be repeated over and over with the expected result.
Inside a bash script:
cp -R "${1}/App" "${2}"
//change the value in the in-memory object
content.val1 = 42;
//Serialize as JSON and Write it to a file
fs.writeFileSync(filename, JSON.stringify(content));
i think it's just the debugger making it simple. Note that a case and "if list" are not ultimately the same. There is is a reason why case blocks normally end with "break". The case stmt actually looks something like this when broken down in assembly.
if myObject.GetType() == type of Car
GOTO START_CAR
else if myObject.GetType() == type of Bike
GOTO START_BIKE
LABEL START_CAR
//do something car
GOTO END
LABEL START_BIKE
//do something bike
GOTO END
LABEL END
If you don't have the break, then the case blocks would be missing the "GOTO END" stmts, and in fact if you landed in the "car" case you'd actually run both sections
//do something car
//do something bike
GOTO END

I ran into the same snag..and the solution was to push the code to the repo as though it were an existing project and not a brand new one being initialised.
git remote add origin https://github.com/Name/reponame.git
git branch -M main
git push -u origin main
Hmm... I can't reproduce this:
using System;
class Test
{
static void Main()
{
decimal d = decimal.Parse("1200.00");
Console.WriteLine(d); // Prints 1200.00
}
}
Are you sure it's not some other part of your code normalizing the decimal value later?
Just in case it's cultural issues, try this version which shouldn't depend on your locale at all:
using System;
using System.Globalization;
class Test
{
static void Main()
{
decimal d = decimal.Parse("1200.00", CultureInfo.InvariantCulture);
Console.WriteLine(d.ToString(CultureInfo.InvariantCulture));
}
}
From memory, Excel uses the machine-specific ANSI encoding. So this would be Windows-1252 for a EN-US installation, 1251 for Russian, etc.
you can use the custom datetime by using...
create table noteTable3
(created_at DATETIME DEFAULT (STRFTIME('%d-%m-%Y %H:%M', 'NOW','localtime')),
title text not null, myNotes text not null);
use 'NOW','localtime' to get the current system date else it will show some past or other time in your Database after insertion time in your db.
Thanks You...
Something to keep in mind is that this error isn't only due to self signed certs. The new Entrust CA certs fail with the same error, and the right thing to do is to update the server with the appropriate root certs, not to disable this important security feature.
You may want to consider using a different type of loop where that logic is applicable, because it is the most obvious answer.
perhaps a:
i=2
while i < n:
if something:
do something
i += 1
else:
do something else
i = 2 #restart the loop

The best solution, you can manage the multiple node versions using nvm installer. then, install the required node's version using below command
nvm install version
Use below command as a working node with mentioned version alone
nvm use version
now, you can use any version node without uninstalling previous installed node.
My Answer: All of the following should be overridden (i.e. describe them all within columndefinition
, if appropriate):
length
precision
scale
nullable
unique
i.e. the column DDL will consist of: name
+ columndefinition
and nothing else.
Rationale follows.
Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.
Other annotation purely logical - properties used in-memory in java to control JPA processing.
That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true)
and once via @Column(...,nullable=true)
. Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.
In your example, length and nullable properties are overridden and redundant.
So, when specifying columnDefinition, what other properties of @Column are made redundant?
In JPA Spec & javadoc:
columnDefinition
definition:
The SQL fragment that is used when generating the DDL for the column.
columnDefinition
default:
Generated SQL to create a column of the inferred type.
The following examples are provided:
@Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
@Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
And, err..., that's it really. :-$ ?!
Does columnDefinition override other properties provided in the same annotation?
The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.
The following can be safely implied from examples provided in the JPA spec
name
& table
can be used in conjunction with columnDefinition
, neither are overriddennullable
is overridden/made redundant by columnDefinition
The following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):
length
, precision
, scale
are overridden/made redundant by the columnDefinition
- they are integral to the typeinsertable
and updateable
are provided separately and never included in columnDefinition
, because they control SQL generation in-memory, before it is emmitted to the database.That leaves just the "unique
" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.
Test My Answer For columns "A" & "B", respectively:
@Column(name="...", table="...", insertable=true, updateable=false,
columndefinition="NUMBER(5,2) NOT NULL UNIQUE"
@Column(name="...", table="...", insertable=false, updateable=true,
columndefinition="NVARCHAR2(100) NULL"
In SQL Server Import and Export Wizard you can adjust the source data types in the Advanced
tab (these become the data types of the output if creating a new table, but otherwise are just used for handling the source data).
The data types are annoyingly different than those in MS SQL, instead of VARCHAR(255)
it's DT_STR
and the output column width can be set to 255
. For VARCHAR(MAX)
it's DT_TEXT
.
So, on the Data Source selection, in the Advanced
tab, change the data type of any offending columns from DT_STR
to DT_TEXT
(You can select multiple columns and change them all at once).
The ThreadPoolExecutor
class is the base implementation for the executors that are returned from many of the Executors
factory methods. So let's approach Fixed and Cached thread pools from ThreadPoolExecutor
's perspective.
The main constructor of this class looks like this:
public ThreadPoolExecutor(
int corePoolSize,
int maximumPoolSize,
long keepAliveTime,
TimeUnit unit,
BlockingQueue<Runnable> workQueue,
ThreadFactory threadFactory,
RejectedExecutionHandler handler
)
The corePoolSize
determines the minimum size of the target thread pool. The implementation would maintain a pool of that size even if there are no tasks to execute.
The maximumPoolSize
is the maximum number of threads that can be active at once.
After the thread pool grows and becomes bigger than the corePoolSize
threshold, the executor can terminate idle threads and reach to the corePoolSize
again.
If allowCoreThreadTimeOut
is true, then the executor can even terminate core pool threads if they were idle more than keepAliveTime
threshold.
So the bottom line is if threads remain idle more than keepAliveTime
threshold, they may get terminated since there is no demand for them.
What happens when a new task comes in and all core threads are occupied? The new tasks will be queued inside that BlockingQueue<Runnable>
instance. When a thread becomes free, one of those queued tasks can be processed.
There are different implementations of the BlockingQueue
interface in Java, so we can implement different queuing approaches like:
Bounded Queue: New tasks would be queued inside a bounded task queue.
Unbounded Queue: New tasks would be queued inside an unbounded task queue. So this queue can grow as much as the heap size allows.
Synchronous Handoff: We can also use the SynchronousQueue
to queue the new tasks. In that case, when queuing a new task, another thread must already be waiting for that task.
Here's how the ThreadPoolExecutor
executes a new task:
corePoolSize
threads are running, tries to start a
new thread with the given task as its first job.BlockingQueue#offer
method. The offer
method won't block if the queue is full and immediately returns false
.offer
returns false
), then it tries to add a new thread to the thread pool with this task as its first job.RejectedExecutionHandler
.The main difference between the fixed and cached thread pools boils down to these three factors:
+-----------+-----------+-------------------+---------------------------------+ | Pool Type | Core Size | Maximum Size | Queuing Strategy | +-----------+-----------+-------------------+---------------------------------+ | Fixed | n (fixed) | n (fixed) | Unbounded `LinkedBlockingQueue` | +-----------+-----------+-------------------+---------------------------------+ | Cached | 0 | Integer.MAX_VALUE | `SynchronousQueue` | +-----------+-----------+-------------------+---------------------------------+
Excutors.newFixedThreadPool(n)
works:
public static ExecutorService newFixedThreadPool(int nThreads) {
return new ThreadPoolExecutor(nThreads, nThreads,
0L, TimeUnit.MILLISECONDS,
new LinkedBlockingQueue<Runnable>());
}
As you can see:
OutOfMemoryError
.When should I use one or the other? Which strategy is better in terms of resource utilization?
A fixed-size thread pool seems to be a good candidate when we're going to limit the number of concurrent tasks for resource management purposes.
For example, if we're going to use an executor to handle web server requests, a fixed executor can handle the request bursts more reasonably.
For even better resource management, it's highly recommended to create a custom ThreadPoolExecutor
with a bounded BlockingQueue<T>
implementation coupled with reasonable RejectedExecutionHandler
.
Here's how the Executors.newCachedThreadPool()
works:
public static ExecutorService newCachedThreadPool() {
return new ThreadPoolExecutor(0, Integer.MAX_VALUE,
60L, TimeUnit.SECONDS,
new SynchronousQueue<Runnable>());
}
As you can see:
Integer.MAX_VALUE
. Practically, the thread pool is unbounded.SynchronousQueue
always fails when there is no one on the other end to accept it! When should I use one or the other? Which strategy is better in terms of resource utilization?
Use it when you have a lot of predictable short-running tasks.
These need to go as different commands e.g.:
NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"
The expansion $NAME
to empty string is done by the shell earlier, before running echo
, so at the time the NAME
variable is passed to the echo
command's environment, the expansion is already done (to null string).
To get the same result in one command:
NAME=sam printenv NAME

The answer to this question is, perhaps surprisingly, never, or more realistically, only when you are forced to for interoperability with legacy code. This is the recommendation in Effective Java, 3rd Edition by Joshua Bloch:
There is no reason to use Java serialization in any new system you write
Oracle's chief architect, Mark Reinhold, is on record as saying removing the current Java serialization mechanism is a long-term goal.
Java provides as part of the language a serialization scheme you can opt in to, by using the Serializable
interface. This scheme however has several intractable flaws and should be treated as a failed experiment by the Java language designers.
Instead, use a serialization scheme that you can explicitly control. Such as Protocol Buffers, JSON, XML, or your own custom scheme.

Depending on your use case, instead of using a case statement, you can use the union of multiple select statements, one for each condition.
My goal when I found this question was to select multiple columns conditionally. I didn't necessarily need the case statement, so this is what I did.
For example:
SELECT
a1,
a2,
a3,
...
WHERE <condition 1>
AND (<other conditions>)
UNION
SELECT
b1,
b2,
b3,
...
WHERE <condition 2>
AND (<other conditions>)
UNION
SELECT
...
-- and so on
Be sure that exactly one condition evaluates to true at a time.
I'm using Postgresql, and the query planner was smart enough to not run a select statement at all if the condition in the where clause evaluated to false (i.e. only one of the select statement actually runs), so this was also performant for me.
Here is a good table for printf
specifiers. So it should be %hu
for unsigned short int
.
And link to Wikipedia "C data types" too.
you can use regular expressions to identify the last comma (,) and replace it with " " as follow:
if(fieldName.endsWith(","))
{
fieldName = fieldName.replace(/,([^,]*)$/," ");
}
Classic scheduling of tasks can be serial, parallel or concurrent.
Serial: tasks must be executed one after the other in a known tricked order or it will not work. Easy enough.
Parallel: tasks must be executed at the same time or it will not work.
Try to avoid this or we will have tears by tea time.
Concurrent: we do not care. We are not careless, though: we have analysed it and it doesn't matter; we can therefore execute any task using any available facility at any time. Happy days.
Often, the available scheduling changes at known events which we call a state change.
People often think this is about software, but it is in fact a systems design concept that pre-dates computers; software systems were a little slow in the uptake, very few software languages even attempt to address the problem. You might try looking up the transputer language occam if you are interested.
Succinctly, systems design addresses the following:
Good luck.

Rather than convert image to bitmap and then rotate it try to rotate direct image view like below code.
ImageView myImageView = (ImageView)findViewById(R.id.my_imageview);
AnimationSet animSet = new AnimationSet(true);
animSet.setInterpolator(new DecelerateInterpolator());
animSet.setFillAfter(true);
animSet.setFillEnabled(true);
final RotateAnimation animRotate = new RotateAnimation(0.0f, -90.0f,
RotateAnimation.RELATIVE_TO_SELF, 0.5f,
RotateAnimation.RELATIVE_TO_SELF, 0.5f);
animRotate.setDuration(1500);
animRotate.setFillAfter(true);
animSet.addAnimation(animRotate);
myImageView.startAnimation(animSet);
Yes, that is supported.
Check the documentation provided here for the supported keywords inside method names.
You can just define the method in the repository interface without using the @Query annotation and writing your custom query. In your case it would be as followed:
List<Inventory> findByIdIn(List<Long> ids);
I assume that you have the Inventory entity and the InventoryRepository interface. The code in your case should look like this:
The Entity
@Entity
public class Inventory implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
// other fields
// getters/setters
}
The Repository
@Repository
@Transactional
public interface InventoryRepository extends PagingAndSortingRepository<Inventory, Long> {
List<Inventory> findByIdIn(List<Long> ids);

The term "strong typing" does not have a definite definition.
Therefore, the use of the term depends on with whom you're speaking.
I do not consider any language, in which the type of a variable is not either explicitly declared, or statically typed to be strongly typed.
Strong typing doesn't just preclude conversion (for example, "automatically" converting from an integer to a string). It precludes assignment (i.e., changing the type of a variable).
If the following code compiles (interprets), the language is not strong-typed:
Foo = 1 Foo = "1"
In a strongly typed language, a programmer can "count on" a type.
For example, if a programmer sees the declaration,
UINT64 kZarkCount;
and he or she knows that 20 lines later, kZarkCount is still a UINT64 (as long as it occurs in the same block) - without having to examine intervening code.
In TSQL, the modulo is done with a percent sign.
SELECT 38 % 5 would give you the modulo 3
Constructors don't return a type , just remove the return type which is void in your case. It would run fine then.
You can create script /etc/cron.hourly/php and put there:
#!/bin/bash
max=24
tmpdir=/tmp
nice find ${tmpdir} -type f -name 'sess_*' -mmin +${max} -delete
Then make the script executable (chmod +x).
Now every hour will be deleted all session files with data modified more than 24 minutes ago.
You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.
SELECT * FROM <table_name> WHERE id = 1
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';
If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':
hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')
If you find that the pretty_generate
option built into Ruby's JSON library is not "pretty" enough, I recommend my own NeatJSON gem for your formatting.
To use it:
gem install neatjson
and then use
JSON.neat_generate
instead of
JSON.pretty_generate
Like Ruby's pp
it will keep objects and arrays on one line when they fit, but wrap to multiple as needed. For example:
{
"navigation.createroute.poi":[
{"text":"Lay in a course to the Hilton","params":{"poi":"Hilton"}},
{"text":"Take me to the airport","params":{"poi":"airport"}},
{"text":"Let's go to IHOP","params":{"poi":"IHOP"}},
{"text":"Show me how to get to The Med","params":{"poi":"The Med"}},
{"text":"Create a route to Arby's","params":{"poi":"Arby's"}},
{
"text":"Go to the Hilton by the Airport",
"params":{"poi":"Hilton","location":"Airport"}
},
{
"text":"Take me to the Fry's in Fresno",
"params":{"poi":"Fry's","location":"Fresno"}
}
],
"navigation.eta":[
{"text":"When will we get there?"},
{"text":"When will I arrive?"},
{"text":"What time will I get to the destination?"},
{"text":"What time will I reach the destination?"},
{"text":"What time will it be when I arrive?"}
]
}
It also supports a variety of formatting options to further customize your output. For example, how many spaces before/after colons? Before/after commas? Inside the brackets of arrays and objects? Do you want to sort the keys of your object? Do you want the colons to all be lined up?
This is an old question, but I stumbled across it and thought I'd share the method I used:
var body = '<div id="anid">some <a href="link">text</a></div> and some more text';
var temp = document.createElement("div");
temp.innerHTML = body;
var sanitized = temp.textContent || temp.innerText;
sanitized
will now contain: "some text and some more text"
Simple, no jQuery needed, and it shouldn't let you down even in more complex cases.
For future readers who need this answer quickly:
2^31-1 = 2.147.483.647 characters
USE:

array([[ 0, 2],
[ 4, 6],

array([[ 0, 2],
[ 4, 6],
[12, 14]])
I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.
Function DoStuff(){
param(
[Parameter(Mandatory=$true)][string]$computername,
[Parameter(Mandatory=$false)][string]$arg2,
[Parameter(Mandatory=$false)][string]$domain
)
if(!($domain)){
$domain = 'domain1'
}
write-host $domain
if($arg2){
write-host "arg2 present... executing script block"
}
else{
write-host "arg2 missing... exiting or whatever"
}
}
Use this.
java.util.Date date = new Date("Sat Dec 01 00:00:00 GMT 2012");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String format = formatter.format(date);
System.out.println(format);
you will get the output as
2012-12-01
I added it for all fieldsets with

I didnt work if I set it separately using for example

On modern Windows this driver isn't available by default anymore, but you can download as Microsoft Access Database Engine 2010 Redistributable on the MS site. If your app is 32 bits be sure to download and install the 32 bits variant because to my knowledge the 32 and 64 bit variant cannot coexist.
Depending on how your app locates its db driver, that might be all that's needed. However, if you use an UDL file there's one extra step - you need to edit that file. Unfortunately, on a 64bits machine the wizard used to edit UDL files is 64 bits by default, it won't see the JET driver and just slap whatever driver it finds first in the UDL file. There are 2 ways to solve this issue:
C:\Windows\syswow64\rundll32.exe "C:\Program Files (x86)\Common Files\System\Ole DB\oledb32.dll",OpenDSLFile C:\path\to\your.udl
. Note that I could use this technique on a Win7 64 Pro, but it didn't work on a Server 2008R2 (could be my mistake, just mentioning)[oledb]
; Everything after this line is an OLE DB initstring
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Path\To\The\database.mdb;Persist Security Info=False
That should allow your app to start correctly.
One option is to pass in Bar.class
(or whatever type you're interested in - any way of specifying the appropriate Class<T>
reference) and keep that value as a field:
public class Test {
public static void main(String[] args) throws IllegalAccessException,
InstantiationException {
Generic<Bar> x = new Generic<>(Bar.class);
Bar y = x.buildOne();
}
}
public class Generic<T> {
private Class<T> clazz;
public Generic(Class<T> clazz) {
this.clazz = clazz;
}
public T buildOne() throws InstantiationException, IllegalAccessException {
return clazz.newInstance();
}
}
public class Bar {
public Bar() {
System.out.println("Constructing");
}
}
Another option is to have a "factory" interface, and you pass a factory to the constructor of the generic class. That's more flexible, and you don't need to worry about the reflection exceptions.
For pandas 0.10, where iloc
is unavalable, filter a DF
and get the first row data for the column VALUE
:
df_filt = df[df['C1'] == C1val & df['C2'] == C2val]
result = df_filt.get_value(df_filt.index[0],'VALUE')
if there is more then 1 row filtered, obtain the first row value. There will be an exception if the filter result in empty data frame.
use float:left on the div and the link, or use a span.
In addition to --date=(relative|local|default|iso|iso-strict|rfc|short|raw)
, as others have mentioned, you can also use a custom log date format with
--date=format:'%Y-%m-%d %H:%M:%S'
This outputs something like 2016-01-13 11:32:13
.
NOTE: If you take a look at the commit linked to below, I believe you'll need at least Git v2.6.0-rc0 for this to work.
In a full command it would be something like:
git config --global alias.lg "log --graph --decorate
-30 --all --date-order --date=format:'%Y-%m-%d %H:%M:%S'
--pretty=format:'%C(cyan)%h%Creset %C(black bold)%ad%Creset%C(auto)%d %s'"
I haven't been able to find this in documentation anywhere (if someone knows where to find it, please comment) so I originally found the placeholders by trial and error.
In my search for documentation on this I found a commit to Git itself that indicates the format is fed directly to strftime
. Looking up strftime
(here or here) the placeholders I found match the placeholders listed.
The placeholders include:
%a Abbreviated weekday name
%A Full weekday name
%b Abbreviated month name
%B Full month name
%c Date and time representation appropriate for locale
%d Day of month as decimal number (01 – 31)
%H Hour in 24-hour format (00 – 23)
%I Hour in 12-hour format (01 – 12)
%j Day of year as decimal number (001 – 366)
%m Month as decimal number (01 – 12)
%M Minute as decimal number (00 – 59)
%p Current locale's A.M./P.M. indicator for 12-hour clock
%S Second as decimal number (00 – 59)
%U Week of year as decimal number, with Sunday as first day of week (00 – 53)
%w Weekday as decimal number (0 – 6; Sunday is 0)
%W Week of year as decimal number, with Monday as first day of week (00 – 53)
%x Date representation for current locale
%X Time representation for current locale
%y Year without century, as decimal number (00 – 99)
%Y Year with century, as decimal number
%z, %Z Either the time-zone name or time zone abbreviation, depending on registry settings
%% Percent sign
In a full command it would be something like
git config --global alias.lg "log --graph --decorate -30 --all --date-order --date=format:'%Y-%m-%d %H:%M:%S' --pretty=format:'%C(cyan)%h%Creset %C(black bold)%ad%Creset%C(auto)%d %s'"
I can't speak to other versions of SQL Server, but in 2012, outputting directly works just fine. You don't need to bother with a temporary table.
INSERT INTO MyTable
OUTPUT INSERTED.ID
VALUES (...)
By the way, this technique also works when inserting multiple rows.
INSERT INTO MyTable
OUTPUT INSERTED.ID
VALUES
(...),

I struggled with redirect not working for very long, none of what mentioned above was working for me, until I tried this:
Change:
return $this->redirect('site/secure');
to:
return $this->redirect(['site/secure']);
In other words, needed to enclose it within [] brackets! I am using PHP 7, might be the reason why?
Let's make a Go 1-compatible list of all the ways to read and write files in Go.
Because file API has changed recently and most other answers don't work with Go 1. They also miss bufio
which is important IMHO.
In the following examples I copy a file by reading from it and writing to the destination file.
Start with the basics
package main
import (
"io"
"os"
)
func main() {
// open input file
fi, err := os.Open("input.txt")
if err != nil {
panic(err)
}
// close fi on exit and check for its returned error
defer func() {
if err := fi.Close(); err != nil {
panic(err)
}
}()
// open output file
fo, err := os.Create("output.txt")
if err != nil {
panic(err)
}
// close fo on exit and check for its returned error
defer func() {
if err := fo.Close(); err != nil {
panic(err)
}
}()
// make a buffer to keep chunks that are read
buf := make([]byte, 1024)
for {
// read a chunk
n, err := fi.Read(buf)
if err != nil && err != io.EOF {
panic(err)
}
if n == 0 {
break
}
// write a chunk
if _, err := fo.Write(buf[:n]); err != nil {
panic(err)
}
}
}
Here I used os.Open
and os.Create
which are convenient wrappers around os.OpenFile
. We usually don't need to call OpenFile
directly.
Notice treating EOF. Read
tries to fill buf
on each call, and returns io.EOF
as error if it reaches end of file in doing so. In this case buf
will still hold data. Consequent calls to Read
returns zero as the number of bytes read and same io.EOF
as error. Any other error will lead to a panic.
Using bufio
package main
import (
"bufio"
"io"
"os"
)
func main() {
// open input file
fi, err := os.Open("input.txt")
if err != nil {
panic(err)
}
// close fi on exit and check for its returned error
defer func() {
if err := fi.Close(); err != nil {
panic(err)
}
}()
// make a read buffer
r := bufio.NewReader(fi)
// open output file
fo, err := os.Create("output.txt")
if err != nil {
panic(err)
}
// close fo on exit and check for its returned error
defer func() {
if err := fo.Close(); err != nil {
panic(err)
}
}()
// make a write buffer
w := bufio.NewWriter(fo)
// make a buffer to keep chunks that are read
buf := make([]byte, 1024)
for {
// read a chunk
n, err := r.Read(buf)
if err != nil && err != io.EOF {
panic(err)
}
if n == 0 {
break
}
// write a chunk
if _, err := w.Write(buf[:n]); err != nil {
panic(err)
}
}
if err = w.Flush(); err != nil {
panic(err)
}
}
bufio
is just acting as a buffer here, because we don't have much to do with data. In most other situations (specially with text files) bufio
is very useful by giving us a nice API for reading and writing easily and flexibly, while it handles buffering behind the scenes.
Note: The following code is for older Go versions (Go 1.15 and before). Things have changed. For the new way, take a look at this answer.
Using ioutil
package main
import (
"io/ioutil"
)
func main() {
// read the whole file at once
b, err := ioutil.ReadFile("input.txt")
if err != nil {
panic(err)
}
// write the whole body at once
err = ioutil.WriteFile("output.txt", b, 0644)
if err != nil {
panic(err)
}
}
Easy as pie! But use it only if you're sure you're not dealing with big files.
You can solve this issue by calling a:link
and a:visited
selectors together. And follow it with a:hover
selector.
a:link, a:visited
{color: gray;}
a:hover
{color: skyblue;}
This can be achieved by putting padding between the columns using CSS. You can either add padding to the left of all columns except the first, or add padding to the right of all columns except the last. You should avoid adding padding to the right of the last column or to the left of the first as this will insert redundant white space. You should also avoid being too prescriptive with classes to specify which columns should have the additional padding as this will make maintenance harder if you later add a new column.
The 'lobotomised owl selector' allows you to select all siblings, regardless of if they are a th
, td
or something else.
tr > * + * {
padding-left: 4em;
}

For me, fny answers really got it all. since fetch is not throwing error, we need to throw/handle the error ourselves. Posting my solution with async/await. I think it's more strait forward and readable
Solution 1: Not throwing an error, handle the error ourselves
async _fetch(request) {
const fetchResult = await fetch(request); //Making the req
const result = await fetchResult.json(); // parsing the response
if (fetchResult.ok) {
return result; // return success object
}
const responseError = {
type: 'Error',
message: result.message || 'Something went wrong',
data: result.data || '',
code: result.code || '',
};
const error = new Error();
error.info = responseError;
return (error);
}
Here if we getting an error, we are building an error object, plain JS object and returning it, the con is that we need to handle it outside. How to use:
const userSaved = await apiCall(data); // calling fetch
if (userSaved instanceof Error) {
debug.log('Failed saving user', userSaved); // handle error
return;
}
debug.log('Success saving user', userSaved); // handle success
Solution 2: Throwing an error, using try/catch
async _fetch(request) {
const fetchResult = await fetch(request);
const result = await fetchResult.json();
if (fetchResult.ok) {
return result;
}
const responseError = {
type: 'Error',
message: result.message || 'Something went wrong',
data: result.data || '',
code: result.code || '',
};
let error = new Error();
error = { ...error, ...responseError };
throw (error);
}
Here we are throwing and error that we created, since Error ctor approve only string, Im creating the plain Error js object, and the use will be:
try {
const userSaved = await apiCall(data); // calling fetch
debug.log('Success saving user', userSaved); // handle success
} catch (e) {
debug.log('Failed saving user', userSaved); // handle error
}
Solution 3: Using customer error
async _fetch(request) {
const fetchResult = await fetch(request);
const result = await fetchResult.json();
if (fetchResult.ok) {
return result;
}
throw new ClassError(result.message, result.data, result.code);
}
And:
class ClassError extends Error {
constructor(message = 'Something went wrong', data = '', code = '') {
super();
this.message = message;
this.data = data;
this.code = code;
}
}
Hope it helped.
sa
is enabledAn example statement that uses a sub-select :
select * into MyNewTable
from
(
select

from
[SomeOtherTablename]
where
EventStartDatetime >= '01/JAN/2018'
)
) mysourcedata
;
note that the sub query must be given a name .. any name .. e.g. above example gives the subquery a name of mysourcedata. Without this a syntax error is issued in SQL*server 2012.
The database should reply with a message like: (9999 row(s) affected)

Two arrays can be easily added or union without chaning their original indexing by + operator. This will be very help full in laravel and codeigniter select dropdown.
$empty_option = array(
''=>'Select Option'
);
$option_list = array(
1=>'Red',
2=>'White',
3=>'Green',
);
$arr_option = $empty_option + $option_list;
Output will be :
$arr_option = array(
''=>'Select Option'
1=>'Red',
2=>'White',
3=>'Green',
);
The only time I factor in extra time for testing is if I'm unfamiliar with the testing technology I'll be using (e.g. using Selenium tests for the first time). Then I factor in maybe 10-20% for getting up to speed on the tools and getting the test infrastructure in place.
Otherwise testing is just an innate part of development and doesn't warrant an extra estimate. In fact, I'd probably increase the estimate for code done without tests.
EDIT: Note that I'm usually writing code test-first. If I have to come in after the fact and write tests for existing code that's going to slow things down. I don't find that test-first development slows me down at all except for very exploratory (read: throw-away) coding.
I'm having the same issue here and I was a bit afraid of checking the last box, since I have no idea what the 3rd party SDK will do with the data collected and if they will respect the Limit Ad Settings.
But I found a post by a Google Admob programmer, Eric Leichtenschlag, on their forums:
The Google Mobile Ads SDK and the Google Conversion Tracking SDK utilize Apple's advertising identifier introduced in iOS 6 (IDFA). While each developer is responsible for how they access device data, the SDKs use IDFA under the guidelines laid out in the iOS developer program license agreement, including Limit Ad Tracking.
Including Limit Ad Tracking. This is what the last box is all about. So you must check the that box if you use AdMob. If you use other SDK I strongly recommend checking if they respect the guidelines as well.
Since I run only ads (Google AdMob), I checked the first (Serve ads...) and last box (I, ___, confirm...). App was approved and released, no issues.

Now since the GhostDriver comes bundled with the PhantomJS, it has become even more convenient to use it through Selenium.
I tried the Node installation of PhantomJS, as suggested by Pykler, but in practice I found it to be slower than the standalone installation of PhantomJS. I guess standalone installation didn't provided these features earlier, but as of v1.9, it very much does so.
Now you can use like this
import selenium.webdriver
driver = selenium.webdriver.PhantomJS()
driver.get('http://google.com')
# do some processing
driver.quit()
Create a SQLCLR assembly with external access permission that returns the list of files as a result set. There are many examples how to do this, eg. Yet another TVF: returning files from a directory or Trading in xp_cmdshell for SQLCLR (Part 1) - List Directory Contents.
To handle the lazy loading with image existence check I followed this in jQuery-
$('[data-src]').each(function() {
var $image_place_holder_element = $(this);
var image_url = $(this).data('src');
$("<div class='hidden-classe' />").load(image_url, function(response, status, xhr) {
if (!(status == "error")) {
$image_place_holder_element.removeClass('image-placeholder');
$image_place_holder_element.attr('src', image_url);
}
}).remove();
});
Reason: if I am using $image_place_holder_element.load()
method it will be adding the response to the element, so random div and removing it appeared me a good solution. Hope it works for someone trying to implement lazy loading along with url check.
Keep in mind that gdb is a powerful command -capable of low level instructions- so is tied to assembly concepts.
What you are looking for is called de instruction pointer, i.e:
The instruction pointer register points to the memory address which the processor will next attempt to execute. The instruction pointer is called ip in 16-bit mode, eip in 32-bit mode,and rip in 64-bit mode.
more detail here
all registers available on gdb execution can be shown with:
(gdb) info registers
with it you can find which mode your program is running (looking which of these registers exist)
then (here using most common register rip nowadays, replace with eip or very rarely ip if needed):
(gdb)info line *$rip
will show you line number and file source
(gdb) list *$rip
will show you that line with a few before and after
but probably
(gdb) frame
should be enough in many cases.
The BLOB datatype is best for storing files.
use MAX
in your SELECT
to return on value.. EXAMPLE
INSERT INTO school_year_studentid (student_id,syr_id) VALUES
((SELECT MAX(student_id) FROM student), (SELECT MAX(syr_id) FROM school_year))
instead of
INSERT INTO school_year_studentid (student_id,syr_id) VALUES
((SELECT (student_id) FROM student), (SELECT (syr_id) FROM school_year))
try it without MAX it will more than one value
I'm not actually sure if this fully answers the question, but I had a fun time writing this little function that keeps a stack, sticks to os.path-based manipulations, and returns the list/stack of items.
def components(path):
ret = []
while len(path) > 0:
path, crust = split(path)
ret.insert(0, crust)
return ret
This one has burned me many times. Arrays.asList
creates an unmodifiable list.
From the Javadoc: Returns a fixed-size list backed by the specified array.
Create a new list with the same content:
newList.addAll(Arrays.asList(newArray));
This will create a little extra garbage, but you will be able to mutate it.
Just might be useful for someone:
I could only recover frm files after a disaster, at least I could get the table structure from FRM files by doing the following:
1- create some dummy tables with at least one column and SAME NAME with frm files in a new mysql database.
2-stop mysql service
3- copy and paste the old frm files to newly created table's frm files, it should ask you if you want to overwrite or not for each. replace all.
4-start mysql service, and you have your table structure...

try:
with open( "a.txt" ) as f :
print f.readlines()
except EnvironmentError: # parent of IOError, OSError *and* WindowsError where available
print 'oops'
If you want different handling for errors from the open call vs the working code you could do:
try:
f = open('foo.txt')
except IOError:
print('error')
else:
with f:
print f.readlines()
The most straightforward way (in my opinion) would be to simply put together a CSV file. If you want to get into formatting and actually writing to a *.xlsx file, there are more complicated solutions (and APIs) to do that for you.
As a variant:
var $menu = $('#menucontainer');
$(document).on('click', function (e) {
// If element is opened and click target is outside it, hide it
if ($menu.is(':visible') && !$menu.is(e.target) && !$menu.has(e.target).length) {
$menu.hide();
}
});
It has no problem with stopping event propagation and better supports multiple menus on the same page where clicking on a second menu while a first is open will leave the first open in the stopPropagation solution.
This depends on how you want the # of months to be defined. Answer this questions: 'What is difference in months: Feb 15, 2008 - Mar 12, 2009'. Is it defined by clear cut # of days which depends on leap years- what month it is, or same day of previous month = 1 month.
A calculation for Days:
Feb 15 -> 29 (leap year) = 14 Mar 1, 2008 + 365 = Mar 1, 2009. Mar 1 -> Mar 12 = 12 days. 14 + 365 + 12 = 391 days. Total = 391 days / (avg days in month = 30) = 13.03333
A calculation of months:
Feb 15 2008 - Feb 15 2009 = 12 Feb 15 -> Mar 12 = less than 1 month Total = 12 months, or 13 if feb 15 - mar 12 is considered 'the past month'
Be explicit about the tuples.

In case you use JSTL and you wish to import a class in a tag page instead of a jsp page, the syntax is a little bit different. Replace the word 'page' with the word 'tag'.
Instead of Sandman's correct answer

use
<%@tag import="path.to.your.class"%>
