The official guideline is there now. mgechev/angular2-seed
had alignment with it too. see #857.

Currently Bootstrap 4 uses a background-image with embbed SVG data info that include the color of the SVG shape. Something like:
.carousel-control-prev-icon { background-image:url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23fff' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E"); }
Note the part about fill='%23fff'
it fills the shape with a color, in this case #fff (white), for red simply replace with #f00
Finally, it is safe to include this (same change for next-icon):
.carousel-control-prev-icon {background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='%23f00' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E"); }
The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.
The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.
Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh
(and possibly play.csh
, etc):
PATH=$PATH:/home/me/play
export PATH

Command to create bash script.
The framework class has been modified to require a flag to inform fromHtml()
how to process line breaks. This was added in Nougat, and only touches on the challenge of incompatibilities of this class across versions of Android.
I've published a compatibility library to standardize and backport the class and include more callbacks for elements and styling:
While it is similar to the framework's Html class, some signature changes were required to allow more callbacks. Here's the sample from the GitHub page:
Spanned fromHtml = HtmlCompat.fromHtml(context, source, 0);
// You may want to provide an ImageGetter, TagHandler and SpanCallback:
//Spanned fromHtml = HtmlCompat.fromHtml(context, source, 0,
// imageGetter, tagHandler, spanCallback);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setText(fromHtml);
$.ajax(
{
type: 'post',
url: 'mail.php',
data: form.serialize(),
beforeSend: function()
{
$('.content').html('loading...');
},
success: function(data)
{
$('.content').html(data);
},
error: function()
{
$('.content').html('error');
}
});
have fun playing arround!
if you should have quick loading times which prevent te loading showing, you can add a timeout of some sort.
You can do this using javascript. No need for Jquery or Regex
function isNumeric(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
While implementing
var val = $('yourinputelement').val();
if(isNumeric(val)) { alert('number'); }
else { alert('not number'); }
Update: To check if a string has numbers in them, you can use regular expressions to do that
var matches = val.match(/\d+/g);
if (matches != null) {
alert('number');
}
This is what we use in ASP.NET:
// Stop Caching in IE
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
// Stop Caching in Firefox
Response.Cache.SetNoStore();
It stops caching in Firefox and IE, but we haven't tried other browsers. The following response headers are added by these statements:
Cache-Control: no-cache, no-store
Pragma: no-cache
This is an improved version of @schuttek's answer. It is improved because it correctly return false for primitives (e.g. isSubclassOf(int.class, Object.class) => false) and also correctly handles interfaces (e.g. isSubclassOf(HashMap.class, Map.class) => true).
static public boolean isSubclassOf(final Class<?> clazz, final Class<?> possibleSuperClass)
{
if (clazz == null || possibleSuperClass == null)
{
return false;
}
else if (clazz.equals(possibleSuperClass))
{
return true;
}
else
{
final boolean isSubclass = isSubclassOf(clazz.getSuperclass(), possibleSuperClass);
if (!isSubclass && clazz.getInterfaces() != null)
{
for (final Class<?> inter : clazz.getInterfaces())
{
if (isSubclassOf(inter, possibleSuperClass))
{
return true;
}
}
}
return isSubclass;
}
}
With SSL the encryption is at the transport level, so it takes place before a request is sent.
So everything in the request is encrypted.
There is also a very helpful GUI tool called Product Browser which appears to be made by Microsoft or at least an employee of Microsoft.

I personally had a very easy time locating the GUID I needed with this.
In order to answer your question, we need two elements:
A list of software architecture styles/pattern is shown on the software architecture article on Wikipeida. And you can research on them easily on the web.
In short and general, Procedural is good for a model that follows a procedure, OOP is good for design, and Functional is good for high level programming.
I think you should try reading the history on each paradigm and see why people create it and you can understand them easily.
After understanding them both, you can link the items of architecture styles/patterns to programming paradigms.
Try adding log_errors = Off and check the error_reporting setting whether it's set high enough.
No it's not always wrong. If your loop condition is "while we haven't tried to read past end of file" then you use while (!feof(f))
. This is however not a common loop condition - usually you want to test for something else (such as "can I read more"). while (!feof(f))
isn't wrong, it's just used wrong.
It may very well be a mistake on the original author, however the notion that 1 is true and 0 is false is not a universal concept. In shell scripting 0 is returned for success, and any other number for failure. In other languages such as Ruby, only nil and false are considered false, and any other value is considered true, so in Ruby both 1 and 0 would be considered true.
We may need more information. Here is what I did to reproduce on SQL Server 2008:
CREATE DATABASE [Test] ON PRIMARY
(
NAME = N'Test'
, FILENAME = N'...Test.mdf'
, SIZE = 3072KB
, FILEGROWTH = 1024KB
)
LOG ON
(
NAME = N'Test_log'
, FILENAME = N'...Test_log.ldf'
, SIZE = 1024KB
, FILEGROWTH = 10%
)
COLLATE SQL_Latin1_General_CP850_BIN2
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[MyTable]
(
[SomeCol] [varchar](50) NULL
) ON [PRIMARY]
GO
Insert MyTable( SomeCol )
Select '±' Collate SQL_Latin1_General_CP1_CI_AS
GO
Select SomeCol, SomeCol Collate SQL_Latin1_General_CP1_CI_AS
From MyTable
Results show the original character. Declaring collation in the query should return the proper character from SQL Server's perspective however it may be the case that the presentation layer is then converting to something yet different like UTF-8.
If you are convinced that an OOP approach is superior for the problem you are trying to solve, why would you be trying to solve it with a non-OOP language? It seems like you're using the wrong tool for the job. Use C++ or some other object-oriented C variant language.
If you are asking because you are starting to code on an already existing large project written in C, then you shouldn't try to force your own (or anyone else's) OOP paradigms into the project's infrastructure. Follow the guidelines that are already present in the project. In general, clean APIs and isolated libraries and modules will go a long way towards having a clean OOP-ish design.
If, after all this, you really are set on doing OOP C, read this (PDF).
I've heard from a reliable source that, if you're doing HTML parsing in .Net, you should look at the HTML agility pack again..

Some sample on SO..
A checkbox input is a native element served to implement toggle functionality, we can use that to our benefit.
Utilize the :checked
pseudo class - attach it to a pseudo element of a checkbox (since you can't really affect the background of the input
itself), and change its background accordingly.
input[type="checkbox"]:before {
content: url('images/icon.png');
display: block;
width: 100px;
height: 100px;
}
input[type="checkbox"]:checked:before {
content: url('images/another-icon.png');
}
Here's a full working demo on jsFiddle to illustrate the approach.
This is a bit cumbersome, and we could make some changes to clean up unnecessary stuff; as we're not really applying a background image, but instead setting the element's content
, we can omit the pseudo elements and set it directly on the checkbox.
Admittedly, they serve no real purpose here but to mask the native rendering of the checkbox. We could simply remove them, but that would result in a FOUC in best cases, or if we fail to fetch the image, it will simply show a huge checkbox.
Enters the appearance
property:
The
(-moz-)appearance
CSS property is used ... to display an element using a platform-native styling based on the operating system's theme.
we can override the platform-native styling by assigning appearance: none
and bypass that glitch altogether (we would have to account for vendor prefixes, naturally, and the prefix-free form is not supported anywhere, at the moment). The selectors are then simplified, and the code is more robust.
input[type="checkbox"] {
content: url('images/black.cat');
display: block;
width: 200px;
height: 200px;
-webkit-appearance: none;
}
input[type="checkbox"]:checked {
content: url('images/white.cat');
}
Again, a live demo of the refactored version is on jsFiddle.
Note: this only works on webkit for now, I'm trying to have it fixed for gecko engines also. Will post the updated version once I do.
Resolved the problem using Jackson library. Prints are called out of Main class and all POJO classes are created. Here is the code snippets.
MainClass.java
public class MainClass {
public static void main(String[] args) throws JsonParseException,
JsonMappingException, IOException {
String jsonStr = "{\r\n" + " \"id\": 2,\r\n" + " \"socket\": \"0c317829-69bf-
43d6-b598-7c0c550635bb\",\r\n"
+ " \"type\": \"getDashboard\",\r\n" + " \"data\": {\r\n"
+ " \"workstationUuid\": \"ddec1caa-a97f-4922-833f-
632da07ffc11\"\r\n" + " },\r\n"
+ " \"reply\": true\r\n" + "}";
ObjectMapper mapper = new ObjectMapper();
MyPojo details = mapper.readValue(jsonStr, MyPojo.class);
System.out.println("Value for getFirstName is: " + details.getId());
System.out.println("Value for getLastName is: " + details.getSocket());
System.out.println("Value for getChildren is: " +
details.getData().getWorkstationUuid());
System.out.println("Value for getChildren is: " + details.getReply());
}
MyPojo.java
public class MyPojo {
private String id;
private Data data;
private String reply;
private String socket;
private String type;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Data getData() {
return data;
}
public void setData(Data data) {
this.data = data;
}
public String getReply() {
return reply;
}
public void setReply(String reply) {
this.reply = reply;
}
public String getSocket() {
return socket;
}
public void setSocket(String socket) {
this.socket = socket;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
}
Data.java
public class Data {
private String workstationUuid;
public String getWorkstationUuid() {
return workstationUuid;
}
public void setWorkstationUuid(String workstationUuid) {
this.workstationUuid = workstationUuid;
}
}
RESULTS:
Value for getFirstName is: 2 Value for getLastName is: 0c317829-69bf-43d6-b598-7c0c550635bb Value for getChildren is: ddec1caa-a97f-4922-833f-632da07ffc11 Value for getChildren is: true
you can try this
pd.pandas.set_option('display.max_columns', None)
In Python, lambda is a keyword used to define anonymous functions(functions with no name) and that's why they are known as lambda functions.
Basically it is used for defining anonymous functions that can/can't take argument(s) and returns value of data/expression. Let's see an example.
>>> # Defining a lambda function that takes 2 parameters(as integer) and returns their sum
...
>>> lambda num1, num2: num1 + num2
<function <lambda> at 0x1004b5de8>
>>>
>>> # Let's store the returned value in variable & call it(1st way to call)
...
>>> addition = lambda num1, num2: num1 + num2
>>> addition(62, 5)
67
>>> addition(1700, 29)
1729
>>>
>>> # Let's call it in other way(2nd way to call, one line call )
...
>>> (lambda num1, num2: num1 + num2)(120, 1)
121
>>> (lambda num1, num2: num1 + num2)(-68, 2)
-66
>>> (lambda num1, num2: num1 + num2)(-68, 2**3)
-60
>>>
Now let me give an answer of your 2nd question. The 1st answer is also great. This is my own way to explain with another example.
Suppose we have a list of items(integers and strings with numeric contents) as follows,
nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]
and I want to sort it using sorted() function, lets see what happens.
>>> nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]
>>> sorted(nums)
[1, 3, 4, '-1', '-10', '2', '5', '8']
>>>
It didn't give me what I expected as I wanted like below,
['-10', '-1', 1, '2', 3, 4, '5', '8']
It means we need some strategy(so that sorted could treat our string items as an ints) to achieve this. This is why the key keyword argument is used. Please look at the below one.
>>> nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]
>>> sorted(nums, key=int)
['-10', '-1', 1, '2', 3, 4, '5', '8']
>>>
Lets use lambda function as a value of key
>>> names = ["Rishikesh", "aman", "Ajay", "Hemkesh", "sandeep", "Darshan", "Virendra", "Shwetabh"]
>>> names2 = sorted(names)
>>> names2
['Ajay', 'Darshan', 'Hemkesh', 'Rishikesh', 'Shwetabh', 'Virendra', 'aman', 'sandeep']
>>> # But I don't want this o/p(here our intention is to treat 'a' same as 'A')
...
>>> names3 = sorted(names, key=lambda name:name.lower())
>>> names3
['Ajay', 'aman', 'Darshan', 'Hemkesh', 'Rishikesh', 'sandeep', 'Shwetabh', 'Virendra']
>>>
You can define your own function(callable) and provide it as value of key.
Dear programers, I have written the below code for you, just try to understand it and comment your explanation. I would be glad to see your explanation(it's simple).
>>> def validator(item):
... try:
... return int(item)
... except:
... return 0
...
>>> sorted(['gurmit', "0", 5, 2, 1, "front", -2, "great"], key=validator)
[-2, 'gurmit', '0', 'front', 'great', 1, 2, 5]
>>>
I hope it would be useful.
Setting LeftBarButton with Original Image.
let menuButton = UIBarButtonItem(image: UIImage(named: "imagename").withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(classname.functionname))
self.navigationItem.leftBarButtonItem = menuButton
You can try with regular expression
string s;
Regex r = new Regex ("a|b|c");
bool containsAny = r.IsMatch (s);
Excel can display a Date type in a similar manner to a DateTime. Right click on the affected cell, select Format Cells, then under Category select Date and under Type select the type that looks something like this:
3/14/01 1:30 PM
That should do what you requested. I tested sorting on some sample data with this format and it seemed to work fine.
def trim(x):
if x.dtype == object:
x = x.str.split(' ').str[0]
return(x)
df = df.apply(trim)
None of the answer is working for me.
As the error message is package corrupt , I will have to run

Easiest modern method: Alt
+Enter
on
private static final long serialVersionUID = ;
IntelliJ will underline the space after the =
. put your cursor on it and hit alt
+Enter
(Option
+Enter
on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.
If someone is in search for a quick minimal solution,
import signal

signal.signal(signal.SIGINT, call_this_function_if_interrupted)
# The code skipped if interrupted
Power has more precedence than multiply, so:
2**2*3 = (2^2)*3
2*2*3 = 2*2*3
Hi Just addition to VonC comments. I am using ecj compiler to compile my project. it was throwing expcetion that some of the classes are not found. But the project was bulding fine with javac compiler.
So just I added the classes into the classpath(which we have to pass as argument) and now its working fine... :)

The with
function will let you use shorthand column references and sum
will count TRUE
results from the expression(s).
sum(with(aaa, sex==1 & group1==2))
## [1] 3
sum(with(aaa, sex==1 & group2=="A"))
## [1] 2
As @mnel pointed out, you can also do:
nrow(aaa[aaa$sex==1 & aaa$group1==2,])
## [1] 3
nrow(aaa[aaa$sex==1 & aaa$group2=="A",])
## [1] 2
The benefit of that is that you can do:
nrow(aaa)
## [1] 6
And, the behaviour matches Stata's count
almost exactly (syntax notwithstanding).
Depending on why you want to convert from .png to .svg, you may not have to go through the trouble. Converting from .png (raster) to .svg (vector) can be a pain if you are not very familiar with the tools available, or if you are not a graphic designer by trade.
If someone sends you a large, high resolution file (e.g. 1024x1024), you can resize that down to pretty much any size you want in GIMP. Often, you will have problems resizing an image if the resolution (number of pixels per inch) is too low. To rectify this in GIMP, you can:
File -> Open
: your .png fileImage -> Image Properties
: check the Resolution, and the color space. You want a resolution around 300 ppi. In most cases you want the color space to be RGB.Image -> Mode
: set to RGBImage -> Scale Image
: leave the size alone, set and Y resolution to 300 or greater. Hit Scale.Image -> Scale Image
: the resolution should now be 300 and you can now resize the image down to pretty much any size you want.Not as easy as resizing a .svg file, but definitely easier and faster than trying to convert a .png to a .svg, if you already have a big, high-resolution image.
myarray = "abc";
...is the assignation of a pointer on "abc" to the pointer myarray.
This is NOT filling the myarray buffer with "abc".
If you want to fill the myarray buffer manually, without strcpy(), you can use:
myarray[0] = 'a', myarray[1] = 'b', myarray[2] = 'c', myarray[3] = 0;
or
char *ptr = myarray;
*ptr++ = 'a', *ptr++ = 'b', *ptr++ = 'c', *ptr = 0;
Your question is about the difference between a pointer and a buffer (an array). I hope you now understand how C addresses each kind.
Errors you'll see if a RestTemplate
isn't defined
Consider defining a bean of type 'org.springframework.web.client.RestTemplate' in your configuration.
or
No qualifying bean of type [org.springframework.web.client.RestTemplate] found
How to define a RestTemplate
via annotations
Depending on which technologies you're using and what versions will influence how you define a RestTemplate
in your @Configuration
class.
Spring >= 4 without Spring Boot
Simply define an @Bean
:
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
Spring Boot <= 1.3
No need to define one, Spring Boot automatically defines one for you.
Spring Boot >= 1.4
Spring Boot no longer automatically defines a RestTemplate
but instead defines a RestTemplateBuilder
allowing you more control over the RestTemplate
that gets created. You can inject the RestTemplateBuilder
as an argument in your @Bean
method to create a RestTemplate
:
@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
// Do any additional configuration here
return builder.build();
}
Using it in your class
@Autowired
private RestTemplate restTemplate;
or
@Inject
private RestTemplate restTemplate;
One mistake I was making was saving the file as a.condarc
or b.condarc
.
Save it only as .condarc
and paste the following code in the file and save the file in your home directory. Make necessary changes to hostname, user etc.
channels:
- defaults
show_channel_urls: True
allow_other_channels: True
proxy_servers:
http: http://user:pass@hostname:port
https: http://user:pass@hostname:port
ssl_verify: False
I also got the same error using the code:
MailMessage mail = new MailMessage();
mail.To.Add(txtEmail.Text.Trim());
mail.To.Add("[email protected]");
mail.From = new MailAddress("[email protected]");
mail.Subject = "Confirmation of Registration on Job Junction.";
string Body = "Hi, this mail is to test sending mail using Gmail in ASP.NET";
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
// smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address
smtp.Credentials = new System.Net.NetworkCredential("[email protected]", "password");
// smtp.Port = 587;
//Or your Smtp Email ID and Password
smtp.UseDefaultCredentials = false;
// smtp.EnableSsl = true;
smtp.Send(mail);
But moving 2 lines upward fixed the problem:
MailMessage mail = new MailMessage();
mail.To.Add(txtEmail.Text.Trim());
mail.To.Add("[email protected]");
mail.From = new MailAddress("[email protected]");
mail.Subject = "Confirmation of Registration on Job Junction.";
string Body = "Hi, this mail is to test sending mail using Gmail in ASP.NET";
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
// smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address
smtp.UseDefaultCredentials = false;
smtp.EnableSsl = true;
smtp.Credentials = new System.Net.NetworkCredential("[email protected]", "password");
// smtp.Port = 587;
//Or your Smtp Email ID and Password
smtp.Send(mail);
Best way:
if(typeof variable==='undefined' || variable===null) {
/* do your stuff */
}
html code
<div class="image-container">

This should work, since your state will change after the Ajax call, and the parent component will re-render.
render : function () {
var item;
if (this.state.isRequired) {
item = <MyOwnInput attribute={'whatever'} />
} else {
item = <MyOwnInput />
}
return (

You need to start the SQL Server manually. Press

Add a column to your existing data to get rid of the hour:minute:second time stamp on each row:
=DATE(YEAR(A1), MONTH(A1), DAY(A1))
Extend this down the length of your data. Even easier: quit collecting the hh:mm:ss data if you don't need it. Assuming your date/time was in column A, and your value was in column B, you'd put the above formula in column C, and auto-extend it for all your data.
Now, in another column (let's say E), create a series of dates corresponding to each day of the specific month you're interested in. Just type the first date, (for example, 10/7/2016 in E1), and auto-extend. Then, in the cell next to the first date, F1, enter:
=SUMIF(C:C, E1, B:B )
autoextend the formula to cover every date in the month, and you're done. Begin at 1/1/2016, and auto-extend for the whole year if you like.
numpy.random.randint
accepts a third argument (size
) , in which you can specify the size of the output array. You can use this to create your DataFrame
-
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
Here - np.random.randint(0,100,size=(100, 4))
- creates an output array of size (100,4)
with random integer elements between [0,100)
.
Demo -
import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
which produces:
A B C D
0 45 88 44 92
1 62 34 2 86
2 85 65 11 31
3 74 43 42 56
4 90 38 34 93
5 0 94 45 10
6 58 23 23 60
.. .. .. .. ..
One is a column (aka Series), while the other is a DataFrame:
In [1]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])
In [2]: df
Out[2]:
a b
0 1 2
1 3 4
The column 'b' (aka Series):
In [3]: df['b']
Out[3]:
0 2
1 4
Name: b, dtype: int64
The subdataframe with columns (position) in [1]:
In [4]: df[[1]]
Out[4]:
b
0 2
1 4
Note: it's preferable (and less ambiguous) to specify whether you're talking about the column name e.g. ['b'] or the integer location, since sometimes you can have columns named as integers:
In [5]: df.iloc[:, [1]]
Out[5]:
b
0 2
1 4
In [6]: df.loc[:, ['b']]
Out[6]:
b
0 2
1 4
In [7]: df.loc[:, 'b']
Out[7]:
0 2
1 4
Name: b, dtype: int64
Have a look at the AlertDialog docs. As it states, to add a custom view to your alert dialog you need to find the frameLayout and add your view to that like so:
FrameLayout fl = (FrameLayout) findViewById(android.R.id.custom);
fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));
Most likely you are going to want to create a layout xml file for your view, and inflate it:
LayoutInflater inflater = getLayoutInflater();
View twoEdits = inflater.inflate(R.layout.my_layout, f1, false);
They are largely the same, except that:
The alias declaration is compatible with templates, whereas the C style typedef is not.
In case none of the answers work perhaps the following clarifications will help. I followed the top answer and tried to load the program with ADB from the command line to reduce the possible complications and this did not work.
Once enabling PTP mode the ADB devices command would find my Nexus 4, but I could not push to it. I had to use Eclipse and in order for the dialog to display to accept the RSA key described below.
Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key.
path = path.substring(0, path.length() - 5);
Instead of .each, another (perhaps more concise) approach to getting all those prices might be:
var prices = $(products).children("li").map(function() {
return $(this).prop("data-price");
}).get();
additionally you may want to consider filtering the array to get rid of empty or non-numeric array values in case they should exist:
prices = prices.filter(function(n){ return(!isNaN(parseFloat(n))) });
then use Sergey's solution above:
var max = Math.max.apply(Math,prices);
var min = Math.min.apply(Math,prices);
.Split(new string[] { "is Marco and" }, StringSplitOptions.None)
Consider the spaces surronding "is Marco and"
. Do you want to include the spaces in your result, or do you want them removed? It's quite possible that you want to use " is Marco and "
as separator...
var result = from entry in table
where entry.something == value||entry.something == null
select entry;
use that

Try this:
declare @var char(3)
set @var='[%]'
select Address from Accomodation where Address like '%'+@var+'%'
You must use [] cancels the effect of wildcard, so you read % as a normal character, idem about character _
While string interpolation will work, as your question specifies rails 4, you could be using Arel for this and keeping your app database agnostic.
def self.search(query, page=1)
query = "%#{query}%"

You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same timeI would use the toggleClass function in jQuery and define the CSS to the class e.g.
/* start of css */
#user_button.active {
border-bottom-right-radius: 5px;
border-bottom-left-radius: 5px;
-webkit-border-bottom-right-radius: 5px; /* user-agent specific */
-webkit-border-bottom-left-radius: 5px;
-moz-border-radius-bottomright: 5px;
-moz-border-radius-bottomleft: 5px; /* etc... */
}
/* start of js */
$('#user_button').click(function() {
$('#user_options').toggle();
$(this).toggleClass('active');
return false;
})
$.getJSON("example.json", function() {_x000D_
alert("success");_x000D_
})_x000D_
.success(function() { alert("second success"); })_x000D_
.error(function() { alert("error"); })
_x000D_
It is fixed in jQuery 2.x; In jQuery 1.x you will never get an error callback
As many have already stated, as much as you want to test the private methods you shouldn't hack your code or transpiler to make it work for you. Modern day TypeScript will deny most all of the hacks that people have provided so far.
TLDR; if a method should be tested then you should be decoupling the code into a class that you can expose the method to be public to be tested.
The reason you have the method private is because the functionality doesn't necessarily belong to be exposed by that class, and therefore if the functionality doesn't belong there it should be decoupled into it's own class.
I ran across this article that does a great job of explaining how you should tackle testing private methods. It even covers some of the methods here and how why they're bad implementations.

Note: This code is lifted from the blog linked above (I'm duplicating in case the content behind the link changes)

public getUserInformationToDisplay(){
//...
this.getUserAddress();

On Windows: if you had to mount two directories E:\data\dev & E:\data\dev2
Use:
docker run -v E:\data\dev:c:/downloads -v E:\data\dev2 c:/downloads2 -i --publish 1111:80 -P SomeBuiltContainerName:SomeLabel
Open atom editor and then press Alt and menu bar will appear. Now click on View tab and then click on Toggle Menu Bar as seen on this screenshot.
You can also do this as well (shorter cut) instead of having to do instance declaration. You do this in JSON instead.
class Book {
public BookId: number;
public Title: string;
public Author: string;
public Price: number;
public Description: string;
}
var bks: Book[] = [];
bks.push({BookId: 1, Title:"foo", Author:"foo", Price: 5, Description: "foo"}); //This is all done in JSON.
This is almost like the other answer but you don't need a scatter
plot at all, you can simply specify a scatter-plot-like format (fmt
-parameter) for errorbar
:
import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [1, 4, 9, 16]
e = [0.5, 1., 1.5, 2.]
plt.errorbar(x, y, yerr=e, fmt='o')
plt.show()
Result:
A list of the avaiable fmt
parameters can be found for example in the plot
documentation:
character description
'-' solid line style
'--' dashed line style
'-.' dash-dot line style
':' dotted line style
'.' point marker
',' pixel marker
'o' circle marker
'v' triangle_down marker
'^' triangle_up marker
'<' triangle_left marker
'>' triangle_right marker
'1' tri_down marker
'2' tri_up marker
'3' tri_left marker
'4' tri_right marker
's' square marker
'p' pentagon marker
'*' star marker
'h' hexagon1 marker
'H' hexagon2 marker
'+' plus marker
'x' x marker
'D' diamond marker
'd' thin_diamond marker
'|' vline marker
'_' hline marker
I posted a solution for this on my website some time ago. To use it, import a single .js
file:
<script type="text/javascript" src="/hint-textbox.js"></script>
Then annotate whatever inputs you want to have hints with the CSS class hintTextbox
:
<input type="text" name="email" value="enter email" class="hintTextbox" />
More information and example are available here.
Moment.subtract
does not support an argument of type Moment - documentation:
moment().subtract(String, Number);
moment().subtract(Number, String); // 2.0.0
moment().subtract(String, String); // 2.7.0
moment().subtract(Duration); // 1.6.0
moment().subtract(Object);
The simplest solution is to specify the time delta as an object:
// Assumes string is hh:mm:ss
var myString = "03:15:00",
myStringParts = myString.split(':'),
hourDelta: +myStringParts[0],
minuteDelta: +myStringParts[1];
date.subtract({ hours: hourDelta, minutes: minuteDelta});
date.toString()
// -> "Sat Jun 07 2014 06:07:06 GMT+0100"
You can't manipulate :after
, because it's not technically part of the DOM and therefore is inaccessible by any JavaScript. But you can add a new class with a new :after
specified.
CSS:
.pageMenu .active.changed:after {
/* this selector is more specific, so it takes precedence over the other :after */
border-top-width: 22px;
border-left-width: 22px;
border-right-width: 22px;
}
JS:
$('.pageMenu .active').toggleClass('changed');
UPDATE: while it's impossible to directly modify the :after
content, there are ways to read and/or override it using JavaScript. See "Manipulating CSS pseudo-elements using jQuery (e.g. :before and :after)" for a comprehensive list of techniques.
Labelling the attribute is ideal way. MACRO leads to sometime confusion. and by using void(x),we are adding an overhead in processing.
If not using input argument, use
void foo(int __attribute__((unused))key)
{
}
If not using the variable defined inside the function
void foo(int key)
{
int hash = 0;
int bkt __attribute__((unused)) = 0;
api_call(x, hash, bkt);
}
Now later using the hash variable for your logic but doesn’t need bkt. define bkt as unused, otherwise compiler says'bkt set bt not used".
NOTE: This is just to suppress the warning not for optimization.
Even though too much of CLOSE_WAIT connections means there is something wrong with your code in the first and this is accepted not good practice.
You might want to check out: https://github.com/rghose/kill-close-wait-connections
What this script does is send out the ACK which the connection was waiting for.
This is what worked for me.
There isn't any direct equivalent to the goto
concept in Java. There are a few constructs that allow you to do some of the things you can do with a classic goto
.
break
and continue
statements allow you to jump out of a block in a loop or switch statement.break <label>
allow you to jump out of an arbitrary compound statement to any level within a given method (or initializer block).continue <label>
to continue with the next iteration of an outer loop from an inner loop.return
.None of these Java constructs allow you to branch backwards or to a point in the code at the same level of nesting as the current statement. They all jump out one or more nesting (scope) levels and they all (apart from continue
) jump downwards. This restriction helps to avoid the goto "spaghetti code" syndrome inherent in old BASIC, FORTRAN and COBOL code2.
1- The most expensive part of exceptions is the actual creation of the exception object and its stacktrace. If you really, really need to use exception handling for "normal" flow control, you can either preallocate / reuse the exception object, or create a custom exception class that overrides the fillInStackTrace()
method. The downside is that the exception's printStackTrace()
methods won't give you useful information ... should you ever need to call them.
2 - The spaghetti code syndrome spawned the structured programming approach, where you limited in your use of the available language constructs. This could be applied to BASIC, Fortran and COBOL, but it required care and discipline. Getting rid of goto
entirely was a pragmatically better solution. If you keep it in a language, there is always some clown who will abuse it.
I prefer Python 3.x way.
cal = 123.4567
print(f"result {cal:.4E}")
4
indicates how many digits are shown shown in the floating part.
cal = 123.4567
totalDigitInFloatingPArt = 4
print(f"result {cal:.{totalDigitInFloatingPArt}E} ")
use Illuminate\Http\Request;
public function store(Request $request){
dd($request->all());
}
is same in context saying
use Request;
public function store(){
dd(Request::all());
}
The your seems a multi-array, not a JSON object.
If you want access the object like an array, you have to use some sort of key/value, such as:
var JSONObject = {
"city": ["Blankaholm, "Gamleby"],
"date": ["2012-10-23", "2012-10-22"],
"description": ["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
"lat": ["57.586174","16.521841"],
"long": ["57.893162","16.406090"]
}
and access it with:
JSONObject.city[0] // => Blankaholm
JSONObject.date[1] // => 2012-10-22
and so on...
or
JSONObject['city'][0] // => Blankaholm
JSONObject['date'][1] // => 2012-10-22
and so on...
or, in last resort, if you don't want change your structure, you can do something like that:
var JSONObject = {
"data": [
["Blankaholm, "Gamleby"],
["2012-10-23", "2012-10-22"],
["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
["57.586174","16.521841"],
["57.893162","16.406090"]
]
}
JSONObject.data[0][1] // => Gambleby
I don't have rep enough to comment so I'll format an answer, yet it is only a demonstration of the issue in question.
It seems, when element styles are defined in stylesheets they are not visible to getElementById("someElement").style
This code illustrates the issue... Code from below on jsFiddle.
In Test 2, on the first call, the items left value is undefined, and so, what should be a simple toggle gets messed up. For my use I will define my important style values inline, but it does seem to partially defeat the purpose of the stylesheet.
Here's the page code...
<html>
<head>
<style type="text/css">
#test2a{
position: absolute;
left: 0px;
width: 50px;
height: 50px;
background-color: green;
border: 4px solid black;
}
#test2b{
position: absolute;
left: 55px;
width: 50px;
height: 50px;
background-color: yellow;
margin: 4px;
}
</style>
</head>
<body>
<!-- test1 -->
Swap left positions function with styles defined inline.
<a href="javascript:test1();">Test 1</a><br>
<div class="container">
<div id="test1a" style="position: absolute;left: 0px;width: 50px; height: 50px;background-color: green;border: 4px solid black;"></div>
<div id="test1b" style="position: absolute;left: 55px;width: 50px; height: 50px;background-color: yellow;margin: 4px;"></div>
</div>
<script type="text/javascript">
function test1(){
var a = document.getElementById("test1a");
var b = document.getElementById("test1b");
alert(a.style.left + " - " + b.style.left);
a.style.left = (a.style.left == "0px")? "55px" : "0px";
b.style.left = (b.style.left == "0px")? "55px" : "0px";
}
</script>
<!-- end test 1 -->
<!-- test2 -->
<div id="moveDownThePage" style="position: relative;top: 70px;">
Identical function with styles defined in stylesheet.
<a href="javascript:test2();">Test 2</a><br>
<div class="container">
<div id="test2a"></div>
<div id="test2b"></div>
</div>
</div>
<script type="text/javascript">
function test2(){
var a = document.getElementById("test2a");
var b = document.getElementById("test2b");
alert(a.style.left + " - " + b.style.left);
a.style.left = (a.style.left == "0px")? "55px" : "0px";
b.style.left = (b.style.left == "0px")? "55px" : "0px";
}
</script>
<!-- end test 2 -->
</body>
</html>
I hope this helps to illuminate the issue.

To make this complete: while others now solved your problem :) I would like to give you a piece of good advice: don't reinvent the wheel.
size_t forward_length = strlen(forward);
I tried all suggested ways from this question answers and other articles in the web but not working anyway. I tried autocomplete="new-random-value", autocomplete="off" in form element, using client-side script as below but outside of $(document).ready() as one of the user mentioned:
$(':input').on('focus', function () {
$(this).attr('autocomplete', 'off')
});
I found maybe another priority in the browser cause this weird behavior! So I searched more and finally, I read again carefully below lines from this good article:
For this reason, many modern browsers do not support autocomplete="off" for login fields:
If a site sets autocomplete="off" for a , and the form includes username and password input fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page. If a site sets autocomplete="off" for username and password fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page. This is the behavior in Firefox (since version 38), Google Chrome (since 34), and Internet Explorer (since version 11).
If you are defining a user management page where a user can specify a new password for another person, and therefore you want to prevent auto-filling of password fields, you can use autocomplete="new-password"; however, support for this value has not been implemented on Firefox.
It's just worked. I tried in chrome specially and I hope this continues working and help others.
You are using some sort of revision control, right? Then it should be quite simple to restore to the commit before you added the gem, or revert the one where you added it if you have several revisions after that you wish to keep.
Use the return keyword to exit from a method.
public void someMethod() {
//... a bunch of code ...
if (someCondition()) {
return;
}
//... otherwise do the following...
}
Pls note: We may use break statements which are used to break/exit only from a loop, and not the entire program.
To exit from program: System.exit() Method:
System.exit
has status code, which tells about the termination, such as:
exit(0) : Indicates successful termination.
exit(1) or exit(-1) or any non-zero value – indicates unsuccessful termination.
I also found a tool called TCP/IP Test Server [Edit: no longer available from the original developer, but still available via Brothersoft] which seems to do what I need too. But I didn't try it because it is not listed on big freeware-sites (like CNET...) and no source code is published so that it won't reassure a paranoid sysadmin.
With Java 8 Optional
it can be done with:
Optional<Obj> obj = dao.find();
obj.map(obj.setAvailable(true)).orElseGet(() -> {
logger.fatal("Object not available");
return null;
});
Try this code
$('window').scrollDown(function(){$(#div).hide()});
$('window').scrollUp(function(){ $(#div).show() });
The only solution that worked for me and $.each
was definitely causing the error. so i used for loop
and it's not throwing error anymore.
Example code
$.ajax({
type: 'GET',
url: 'https://example.com/api',
data: { get_param: 'value' },
success: function (data) {
for (var i = 0; i < data.length; ++i) {
console.log(data[i].NameGerman);
}
}
});
There are a to of situations where the above CSS solutions do not work. For instance a transparent fixed header and a sticky footer on the same page. To prevent the top bounce in safari messing things and causing flashes on full screen sliders, you can use this.
if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1) {
$window.bind('mousewheel', function(e) {
if (e.originalEvent.wheelDelta / 120 > 0) {
if ($window.scrollTop() < 2) return false;
}
});
}
According to a user on PHP.net site, his efforts to keep session alive failed, so he had to make a workaround.
<?php
$Lifetime = 3600;
$separator = (strstr(strtoupper(substr(PHP_OS, 0, 3)), "WIN")) ? "\\" : "/";
$DirectoryPath = dirname(__FILE__) . "{$separator}SessionData";
//in Wamp for Windows the result for $DirectoryPath
//would be C:\wamp\www\your_site\SessionData
is_dir($DirectoryPath) or mkdir($DirectoryPath, 0777);
if (ini_get("session.use_trans_sid") == true) {
ini_set("url_rewriter.tags", "");
ini_set("session.use_trans_sid", false);
}
ini_set("session.gc_maxlifetime", $Lifetime);
ini_set("session.gc_divisor", "1");
ini_set("session.gc_probability", "1");
ini_set("session.cookie_lifetime", "0");
ini_set("session.save_path", $DirectoryPath);
session_start();
?>
In SessionData folder it will be stored text files for holding session information, each file would be have a name similar to "sess_a_big_hash_here".
.fa-search{
color:#fff;
}
you write that code in css and it would change the color to white or any color you want, you specify it
Just pressing F5 is not always working.
why?
Because your ISP is also caching web data for you.
Solution: Force Refresh.
Force refresh your browser by pressing CTRL + F5 in Firefox or Chrome to clear ISP cache too, instead of just pressing F5
You then can see 200 response instead of 304 in the browser F12 developer tools network tab.
Another trick is to add question mark ?
at the end of the URL string of the requested page:
http://localhost:52199/Customers/Create?
The question mark will ensure that the browser refresh the request without caching any previous requests.
Additionally in Visual Studio you can set the default browser to Chrome in Incognito mode to avoid cache issues while developing, by adding Chrome in Incognito mode as default browser, see the steps (self illustrated):
Besides the powerful options on the "Run Configurations.." on a well configured project you'll see the maven tasks on the Run As as well.
stdout is buffered, so will only output after a newline is printed.
To get immediate output, either:
The implicit make rule for compiling a C program is
%.o:%.c
$(CC) $(CPPFLAGS) $(CFLAGS) -c -o $@ $<
where the $()
syntax expands the variables. As both CPPFLAGS
and CFLAGS
are used in the compiler call, which you use to define include paths is a matter of personal taste. For instance if foo.c
is a file in the current directory
make foo.o CPPFLAGS="-I/usr/include"
make foo.o CFLAGS="-I/usr/include"
will both call your compiler in exactly the same way, namely
gcc -I/usr/include -c -o foo.o foo.c
The difference between the two comes into play when you have multiple languages which need the same include path, for instance if you have bar.cpp
then try
make bar.o CPPFLAGS="-I/usr/include"
make bar.o CFLAGS="-I/usr/include"
then the compilations will be
g++ -I/usr/include -c -o bar.o bar.cpp
g++ -c -o bar.o bar.cpp
as the C++ implicit rule also uses the CPPFLAGS
variable.
This difference gives you a good guide for which to use - if you want the flag to be used for all languages put it in CPPFLAGS
, if it's for a specific language put it in CFLAGS
, CXXFLAGS
etc. Examples of the latter type include standard compliance or warning flags - you wouldn't want to pass -std=c99
to your C++ compiler!
You might then end up with something like this in your makefile
CPPFLAGS=-I/usr/include
CFLAGS=-std=c99
CXXFLAGS=-Weffc++
Some simple changes in order to have a sorted map with pairs that have duplicate values. In the compare method (class ValueComparator) when values are equal do not return 0 but return the result of comparing the 2 keys. Keys are distinct in a map so you succeed to keep duplicate values (which are sorted by keys by the way). So the above example could be modified like this:
public int compare(Object a, Object b) {
if((Double)base.get(a) < (Double)base.get(b)) {
return 1;
} else if((Double)base.get(a) == (Double)base.get(b)) {
return ((String)a).compareTo((String)b);
} else {
return -1;
}
}
}
Crosstab
function is available under the tablefunc
extension. You'll have to create this extension one time for the database.
CREATE EXTENSION tablefunc
;
You can use the below code to create pivot table using cross tab:
create table test_Crosstab( section text,
<br/>status text,
<br/>count numeric)
<br/>insert into test_Crosstab values ( 'A','Active',1)
<br/>,( 'A','Inactive',2)
<br/>,( 'B','Active',4)
<br/>,( 'B','Inactive',5)
select * from crosstab(
<br/>'select section
<br/>,status
<br/>,count
<br/>from test_crosstab'
<br/>)as ctab ("Section" text,"Active" numeric,"Inactive" numeric)
To make this simple, you have two options to reapply your stash:
git stash pop
- Restore back to the saved state, but it deletes the stash from the temporary storage.git stash apply
- Restore back to the saved state and leaves the stash list for possible later reuse.You can read in more detail about git stashes in this article.
May also want to use "documentElement":
var elem = document.createElement("div");
elem.style = "width:100px;height:100px;position:relative;background:#FF0000;";
document.documentElement.appendChild(elem);
If you can do this in java, try:
Example:
RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean();
List<String> jvmArgs = runtimeMXBean.getInputArguments();
for (String arg : jvmArgs) {
System.out.println(arg);
}
You can also have a look at the method findText(const QString & text) from QComboBox; it returns the index of the element which contains the given text, (-1 if not found). The advantage of using this method is that you don't need to set the second parameter when you add an item.
Here is a little example :
/* Create the comboBox */
QComboBox *_comboBox = new QComboBox;
/* Create the ComboBox elements list (here we use QString) */
QList<QString> stringsList;
stringsList.append("Text1");
stringsList.append("Text3");
stringsList.append("Text4");
stringsList.append("Text2");
stringsList.append("Text5");
/* Populate the comboBox */
_comboBox->addItems(stringsList);
/* Create the label */
QLabel *label = new QLabel;
/* Search for "Text2" text */
int index = _comboBox->findText("Text2");
if( index == -1 )
label->setText("Text2 not found !");
else
label->setText(QString("Text2's index is ")
.append(QString::number(_comboBox->findText("Text2"))));
/* setup layout */
QVBoxLayout *layout = new QVBoxLayout(this);
layout->addWidget(_comboBox);
layout->addWidget(label);

newDate.set(year, monthOfYear, dayOfMonth);
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy");
String date = simpleDateFormat.format(newDate.getTime());
}
}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
datePickerDialog.show();
And use this style:
<style name="DatePickerDialogTheme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">@color/colorPrimary</item>
</style>
"\n".charCodeAt(0);
list(df.columns)
This gives you the list of column names of a data frame df.
The browser support status is this:
IE8, Firefox, Opera: $("html")
Chrome, Safari: $("body")
So this works:
bodyelem = $.browser.safari ? $("body") : $("html") ;
bodyelem.animate( {scrollTop: 0}, 500 );

I got the same error in this case:
var result = Db.SystemLog
.Where(log =>
eventTypeValues.Contains(log.EventType)
&& (
search.Contains(log.Id.ToString())
|| log.Message.Contains(search)
|| log.PayLoad.Contains(search)
|| log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)
)
)
.OrderByDescending(log => log.Id)
.Select(r => r);
After spending way too much time debugging, I figured out that error appeared in the logic expression.
The first line search.Contains(log.Id.ToString())
does work fine, but the last line that deals with a DateTime object made it fail miserably:
|| log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)
Remove the problematic line and problem solved.
I do not fully understand why, but it seems as ToString() is a LINQ expression for strings, but not for Entities. LINQ for Entities deals with database queries like SQL, and SQL has no notion of ToString(). As such, we can not throw ToString() into a .Where() clause.
But how then does the first line work? Instead of ToString(), SQL have CAST
and CONVERT
, so my best guess so far is that linq for entities uses that in some simple cases. DateTime objects are not always found to be so simple...
Python doesn't have such types as you describe. There are two types used to represent integral values: int
, which corresponds to platform's int type in C, and long
, which is an arbitrary precision integer (i.e. it grows as needed and doesn't have an upper limit). int
s are silently converted to long
if an expression produces result which cannot be stored in int
.
Since I realized that (the very excellent) answers of this post lack of by
and aggregate
explanations. Here is my contribution.
The by
function, as stated in the documentation can be though, as a "wrapper" for tapply
. The power of by
arises when we want to compute a task that tapply
can't handle. One example is this code:
ct <- tapply(iris$Sepal.Width , iris$Species , summary )
cb <- by(iris$Sepal.Width , iris$Species , summary )
cb
iris$Species: setosa
Min. 1st Qu. Median Mean 3rd Qu. Max.
2.300 3.200 3.400 3.428 3.675 4.400
--------------------------------------------------------------
iris$Species: versicolor
Min. 1st Qu. Median Mean 3rd Qu. Max.
2.000 2.525 2.800 2.770 3.000 3.400
--------------------------------------------------------------
iris$Species: virginica
Min. 1st Qu. Median Mean 3rd Qu. Max.
2.200 2.800 3.000 2.974 3.175 3.800
ct
$setosa
Min. 1st Qu. Median Mean 3rd Qu. Max.
2.300 3.200 3.400 3.428 3.675 4.400
$versicolor
Min. 1st Qu. Median Mean 3rd Qu. Max.
2.000 2.525 2.800 2.770 3.000 3.400
$virginica
Min. 1st Qu. Median Mean 3rd Qu. Max.
2.200 2.800 3.000 2.974 3.175 3.800
If we print these two objects, ct
and cb
, we "essentially" have the same results and the only differences are in how they are shown and the different class
attributes, respectively by
for cb
and array
for ct
.
As I've said, the power of by
arises when we can't use tapply
; the following code is one example:
tapply(iris, iris$Species, summary )
Error in tapply(iris, iris$Species, summary) :
arguments must have same length
R says that arguments must have the same lengths, say "we want to calculate the summary
of all variable in iris
along the factor Species
": but R just can't do that because it does not know how to handle.
With the by
function R dispatch a specific method for data frame
class and then let the summary
function works even if the length of the first argument (and the type too) are different.
bywork <- by(iris, iris$Species, summary )

it works indeed and the result is very surprising. It is an object of class by
that along Species
(say, for each of them) computes the summary
of each variable.
Note that if the first argument is a data frame
, the dispatched function must have a method for that class of objects. For example is we use this code with the mean
function we will have this code that has no sense at all:
by(iris, iris$Species, mean)
iris$Species: setosa
[1] NA
-------------------------------------------
iris$Species: versicolor
[1] NA
-------------------------------------------
iris$Species: virginica
[1] NA
Warning messages:

2: In mean.default(data[x, , drop = FALSE], ...) :

3: In mean.default(data[x, , drop = FALSE], ...) :

aggregate
can be seen as another a different way of use tapply
if we use it in such a way.
at <- tapply(iris$Sepal.Length , iris$Species , mean)
ag <- aggregate(iris$Sepal.Length , list(iris$Species), mean)
at
setosa versicolor virginica
5.006 5.936 6.588
ag
Group.1 x
1 setosa 5.006
2 versicolor 5.936
3 virginica 6.588
The two immediate differences are that the second argument of aggregate
must be a list while tapply
can (not mandatory) be a list and that the output of aggregate
is a data frame while the one of tapply
is an array
.
The power of aggregate
is that it can handle easily subsets of the data with subset
argument and that it has methods for ts
objects and formula
as well.
These elements make aggregate
easier to work with that tapply
in some situations.
Here are some examples (available in documentation):
ag <- aggregate(len ~ ., data = ToothGrowth, mean)
ag
supp dose len
1 OJ 0.5 13.23
2 VC 0.5 7.98
3 OJ 1.0 22.70
4 VC 1.0 16.77
5 OJ 2.0 26.06
6 VC 2.0 26.14
We can achieve the same with tapply
but the syntax is slightly harder and the output (in some circumstances) less readable:
att <- tapply(ToothGrowth$len, list(ToothGrowth$dose, ToothGrowth$supp), mean)
att
OJ VC
0.5 13.23 7.98
1 22.70 16.77
2 26.06 26.14
There are other times when we can't use by
or tapply
and we have to use aggregate
.
ag1 <- aggregate(cbind(Ozone, Temp) ~ Month, data = airquality, mean)
ag1
Month Ozone Temp
1 5 23.61538 66.73077
2 6 29.44444 78.22222
3 7 59.11538 83.88462
4 8 59.96154 83.96154
5 9 31.44828 76.89655
We cannot obtain the previous result with tapply
in one call but we have to calculate the mean along Month
for each elements and then combine them (also note that we have to call the na.rm = TRUE
, because the formula
methods of the aggregate
function has by default the na.action = na.omit
):
ta1 <- tapply(airquality$Ozone, airquality$Month, mean, na.rm = TRUE)
ta2 <- tapply(airquality$Temp, airquality$Month, mean, na.rm = TRUE)
cbind(ta1, ta2)
ta1 ta2
5 23.61538 65.54839
6 29.44444 79.10000
7 59.11538 83.90323
8 59.96154 83.96774
9 31.44828 76.90000
while with by
we just can't achieve that in fact the following function call returns an error (but most likely it is related to the supplied function, mean
):
by(airquality[c("Ozone", "Temp")], airquality$Month, mean, na.rm = TRUE)
Other times the results are the same and the differences are just in the class (and then how it is shown/printed and not only -- example, how to subset it) object:
byagg <- by(airquality[c("Ozone", "Temp")], airquality$Month, summary)
aggagg <- aggregate(cbind(Ozone, Temp) ~ Month, data = airquality, summary)
The previous code achieve the same goal and results, at some points what tool to use is just a matter of personal tastes and needs; the previous two objects have very different needs in terms of subsetting.
For anyone seeking a solution that does not use the command line: ctrl+shift+t

If your user is authenticated, Then Auth::user()->id
will do the trick.
Late to the party, but for future Googlers - don't use the provided answer.
JavaScript has a mechanism of passing objects by reference, while it only passes a shallow copy for values "numbers, strings etc".
In above example, instead of binding attributes of a service, why don't we expose the service to the scope?
$scope.hello = HelloService;
This simple approach will make angular able to do two-way binding and all the magical things you need. Don't hack your controller with watchers or unneeded markup.
And if you are worried about your view accidentally overwriting your service attributes, use defineProperty
to make it readable, enumerable, configurable, or define getters and setters. You can gain lots of control by making your service more solid.
Final tip: if you spend your time working on your controller more than your services then you are doing it wrong :(.
In that particular demo code you supplied I would recommend you do:
function TimerCtrl1($scope, Timer) {
$scope.timer = Timer;
}
///Inside view
{{ timer.time_updated }}
{{ timer.other_property }}
etc...
Edit:
As I mentioned above, you can control the behaviour of your service attributes using defineProperty
Example:
// Lets expose a property named "propertyWithSetter" on our service
// and hook a setter function that automatically saves new value to db !
Object.defineProperty(self, 'propertyWithSetter', {
get: function() { return self.data.variable; },
set: function(newValue) {
self.data.variable = newValue;
// let's update the database too to reflect changes in data-model !
self.updateDatabaseWithNewData(data);
},
enumerable: true,
configurable: true
});
Now in our controller if we do
$scope.hello = HelloService;
$scope.hello.propertyWithSetter = 'NEW VALUE';
our service will change the value of propertyWithSetter
and also post the new value to database somehow!
Or we can take any approach we want.
Refer to the MDN documentation for defineProperty
.
You could try this:
$width:auto;
@mixin clearfix($width) {
@if $width == 'auto' {
// if width is not passed, or empty do this
} @else {
display: inline-block;
width: $width;
}
}
I'm not sure of your intended result, but setting a default value should return false.
You can pass data to the view using the with
method.
return View::make('blog')->with('posts', $posts);
mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given
This means that the first parameter you passed is a boolean (true or false).
The first parameter is $result
, and it is false
because there is a syntax error in the query.
" ... WHERE PartNumber = $partid';"
You should never directly include a request variable in a SQL query, else the users are able to inject SQL in your queries. (See SQL injection.)
You should escape the variable:
" ... WHERE PartNumber = '" . mysqli_escape_string($conn,$partid) . "';"
Or better, use Prepared Statements
.
PostgreSQL 13 supports natively gen_random_uuid ():
PostgreSQL includes one function to generate a UUID:
gen_random_uuid () ? uuid
This function returns a version 4 (random) UUID. This is the most commonly used type of UUID and is appropriate for most applications.
This is an old topic, but in case anyone else is still looking...
I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)
However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.
So I wrote the small sub below to force the error - hope it's useful.
Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

Try to test and initialize your arrays before you use them :
if( !isset($catagory[$i]) ) $catagory[$i] = '' ;
if( !isset($task[$i]) ) $task[$i] = '' ;
if( !isset($fullText[$i]) ) $fullText[$i] = '' ;
if( !isset($dueDate[$i]) ) $dueDate[$i] = '' ;
if( !isset($empId[$i]) ) $empId[$i] = '' ;
If $catagory[$i]
doesn't exist, you create (Uninitialized) one ... that's all ;
=> PHP try to read on your table in the address $i
, but at this address, there's nothing, this address doesn't exist => PHP return you a notice, and it put nothing to you string.
So you code is not very clean, it takes you some resources that down you server's performance (just a very little).
Take care about your MySQL tables default values
if( !isset($dueDate[$i]) ) $dueDate[$i] = '0000-00-00 00:00:00' ;
or
if( !isset($dueDate[$i]) ) $dueDate[$i] = 'NULL' ;

NSDictionary *dictFromData = [NSJSONSerialization JSONObjectWithData:dataFromDict

There are a few operations you can only do with DI/SI (or their extended counterparts, if you didn't learn ASM in 1985). Among these are
REP STOSB
REP MOVSB
REP SCASB
Which are, respectively, operations for repeated (= mass) storing, loading and scanning. What you do is you set up SI and/or DI to point at one or both operands, perhaps put a count in CX and then let 'er rip. These are operations that work on a bunch of bytes at a time, and they kind of put the CPU in automatic. Because you're not explicitly coding loops, they do their thing more efficiently (usually) than a hand-coded loop.
Just in case you're wondering: Depending on how you set the operation up, repeated storing can be something simple like punching the value 0 into a large contiguous block of memory; MOVSB is used, I think, to copy data from one buffer (well, any bunch of bytes) to another; and SCASB is used to look for a byte that matches some search criterion (I'm not sure if it's only searching on equality, or what – you can look it up :) )
That's most of what those regs are for.
This is an older post but I want to also mention that if you have something like
insert into blah
select * from blah2
and blah and blah2 are identical keep in mind that a computed column will throw this same error...
I just realized that when the above failed and I tried
insert into blah (cola, colb, colc)
select cola, colb, colc from blah2
In my example it was fullname field (computed from first and last, etc)
I have the log4j.properties configured properly. That's not the problem. After a while I discovered that the problem was in Eclipse IDE which had an old build in "cache" and didn't create a new one (Maven dependecy problem). I had to build the project manually and now it works.
In most browsers, there's a slightly more succinct way of removing an element from the DOM than calling .removeChild(element)
on its parent, which is to just call element.remove()
. In due course, this will probably become the standard and idiomatic way of removing an element from the DOM.
The .remove()
method was added to the DOM Living Standard in 2011 (commit), and has since been implemented by Chrome, Firefox, Safari, Opera, and Edge. It was not supported in any version of Internet Explorer.
If you want to support older browsers, you'll need to shim it. This turns out to be a little irritating, both because nobody seems to have made a all-purpose DOM shim that contains these methods, and because we're not just adding the method to a single prototype; it's a method of ChildNode
, which is just an interface defined by the spec and isn't accessible to JavaScript, so we can't add anything to its prototype. So we need to find all the prototypes that inherit from ChildNode
and are actually defined in the browser, and add .remove
to them.
Here's the shim I came up with, which I've confirmed works in IE 8.
(function () {
var typesToPatch = ['DocumentType', 'Element', 'CharacterData'],
remove = function () {
// The check here seems pointless, since we're not adding this
// method to the prototypes of any any elements that CAN be the
// root of the DOM. However, it's required by spec (see point 1 of
// https://dom.spec.whatwg.org/#dom-childnode-remove) and would
// theoretically make a difference if somebody .apply()ed this
// method to the DOM's root node, so let's roll with it.
if (this.parentNode != null) {
this.parentNode.removeChild(this);
}
};
for (var i=0; i<typesToPatch.length; i++) {
var type = typesToPatch[i];
if (window[type] && !window[type].prototype.remove) {
window[type].prototype.remove = remove;
}
}
})();
This won't work in IE 7 or lower, since extending DOM prototypes isn't possible before IE 8. I figure, though, that on the verge of 2015 most people needn't care about such things.
Once you've included them shim, you'll be able to remove a DOM element element
from the DOM by simply calling
element.remove();

I wanted the dropdown to select the matching value of the id in the action method. The trick is to set the Selected property when creating the SelectListItem Collection. It would not work any other way, perhaps I missed something but in end, it is more elegant in my option.
You can write any method that returns a boolean to set the Selected value based on your requirements, in my case I used the existing Equal Method
public ActionResult History(long id)
{
var app = new AppLogic();
var historyVM = new ActivityHistoryViewModel();
historyVM.ProcessHistory = app.GetActivity(id);
historyVM.Process = app.GetProcess(id);
var processlist = app.GetProcessList();
historyVM.ProcessList = from process in processlist
select new SelectListItem
{
Text = process.ProcessName,
Value = process.ID.ToString(),
Selected = long.Equals(process.ID, id)
};
var listitems = new List<SelectListItem>();
return View(historyVM);
}

For New versions
Older versions of python may not have pip installed and get-pip will throw errors. Please update your python (2.7.15 as of Aug 12, 2018).
All current versions have an option to install pip and add it to the path.
Steps:
Powershell
as admin. (win+x
then a
)python -m pip install <package>
.If python is not in PATH, it'll throw an error saying unrecognized cmd. To fix, simply add it to the path as mentioned below.
[OLD Answer]
Python 2.7 must be having pip pre-installed.
Try installing your package by:
win+x
then a
)C:\Python27\Scripts
pip install "package name"
.Note: Else reinstall python: https://www.python.org/downloads/
Also note: You must be in C:\Python27\Scripts
in order to use pip command, Else add it to your path by typing:
[Environment]::SetEnvironmentVariable("Path","$env:Path;C:\Python27\;C:\Python27\Scripts\", "User")
Try this code
HashMap<String, String> map = new HashMap<String, String>();
map.put("EmpID", EmpID);
map.put("UnChecked", "1");
If you don't want to copy the whole tree (with subdirs etc), use or glob.glob("path/to/dir/*.*")
to get a list of all the filenames, loop over the list and use shutil.copy
to copy each file.
for filename in glob.glob(os.path.join(source_dir, '*.*')):
shutil.copy(filename, dest_dir)
You will need to make sure about timeouts between you and the file. In this case PHP and Curl.
To tell Curl to never timeout when a transfer is still active, you need to set CURLOPT_TIMEOUT
to 0
, instead of 1000
.
curl_setopt($ch, CURLOPT_TIMEOUT, 0);
In PHP, again, you must remove time limits or PHP it self (after 30 seconds by default) will kill the script along Curl's request. This alone should fix your issue.
In addition, if you require data integrity, you could add a layer of security by using ignore_user_abort
:
# The maximum execution time, in seconds. If set to zero, no time limit is imposed.
set_time_limit(0);
# Make sure to keep alive the script when a client disconnect.
ignore_user_abort(true);
A client disconnection will interrupt the execution of the script and possibly damaging data,
eg. non-transitional database query, building a config file, ecc., while in your case it would download a partial file... and you might, or not, care about this.
Answering this old question because this thread is at the top on engine searches for CURL_TIMEOUT
.
Script to remove special characters from all fields with class portlet-form-input-field:
// Remove special chars from input field on paste
jQuery('.portlet-form-input-field').bind('paste', function(e) {
var textInput = jQuery(this);
setTimeout(function() {
textInput.val(replaceSingleEndOfLineCharactersInString(textInput.val()));
}, 200);
});
function replaceSingleEndOfLineCharactersInString(value) {
<%
// deal with end-of-line characters (\n or \r\n) that will affect string length calculation,
// also remove all non-printable control characters that can cause XML validation errors
%>
if (value != "") {
value = value.replace(/(\x00|\x01|\x02|\x03|\x04|\x05|\x06|\x07|\x08|\x0B|\x0C|\x0E|\x0F|\x10|\x11|\x12|\x13|\x14|\x15|\x16|\x17|\x18|\x19|\x1A|\x1B|\x1C|\x1D|\x1E|\x1F|\x7F)/gm,'');
return value = value.replace(/(\r\n|\n|\r)/gm,'##').replace(/(\#\#)/gm,"\r\n");
}
}
Now, if the repository is already existing on a remote machine, and you do not have anything locally, you do git clone instead.
The URL format is simple, it is PROTOCOL:/[user@]remoteMachineAddress/path/to/repository.git
For example, cloning a repository on a machine to which you have SSH access using the "dev" user, residing in /srv/repositories/awesomeproject.git and that machine has the ip 10.11.12.13 you do:
git clone ssh://[email protected]/srv/repositories/awesomeproject.git
My copy of C in a Nutshell reveals the existence of a standard function called copysign which might be useful. It looks as if copysign(1.0, -2.0) would return -1.0 and copysign(1.0, 2.0) would return +1.0.
Pretty close huh?
css cannot be directly applied for the alignment of the anchor tag. The css (text-align:center;) should be applied to the parent div/element for the alignment effect to take place on the anchor tag.
You can save it first, then import it.

You cannot.
JavaScript cannot access files on the local computer for security reasons, even to check their size.
The only thing you can do is use JavaScript to submit the form with the file
field to a server-side script, which can then measure its size and return it.
YUI has by far the best stylesheet utility I have seen out there. I encourage you to check it out, but here's a taste:
// style element or locally sourced link element
var sheet = YAHOO.util.StyleSheet(YAHOO.util.Selector.query('style',null,true));
sheet = YAHOO.util.StyleSheet(YAHOO.util.Dom.get('local'));
// OR the id of a style element or locally sourced link element
sheet = YAHOO.util.StyleSheet('local');
// OR string of css text
var css = ".moduleX .alert { background: #fcc; font-weight: bold; } " +
".moduleX .warn { background: #eec; } " +
".hide_messages .moduleX .alert, " +
".hide_messages .moduleX .warn { display: none; }";
sheet = new YAHOO.util.StyleSheet(css);
There are obviously other much simpler ways of changing styles on the fly such as those suggested here. If they make sense for your problem, they might be best, but there are definitely reasons why modifying css is a better solution. The most obvious case is when you need to modify a large number of elements. The other major case is if you need your style changes to involve the cascade. Using the dom to modify an element will always have a higher priority. Its the sledgehammer approach and is equivalent to using the style attribute directly on the html element. That is not always the desired effect.
I solved the problem with the following steps:
Open "services.msc" from command / Windows RUN.
Find the service (which is greyed out).
Double click on that service and go to the "Recovery" tab.
Ensure that
and Press OK.
Now, the service will not try to restart and you can able to delete the greyed out service from services list (i.e. greyed out will be gone).
Use break
.
Unrelated to your question, I see in your code the line:
Violated = !(name.firstname == null) ? false : true;
In this line, you take a boolean value (name.firstname == null)
. Then, you apply the !
operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null)
. Why not use that, as in:
Violated = (name.firstname == null);
When you checkout to a commit git checkout <commit-hash>
or to a remote branch your HEAD will get detached and try to create a new commit on it.
Commits that are not reachable by any branch or tag will be garbage collected and removed from the repository after 30 days.
Another way to solve this is by creating a new branch for the newly created commit and checkout to it. git checkout -b <branch-name> <commit-hash>
This article illustrates how you can get to detached HEAD state.
For infinite scrolling with days it's important you have the good fragment in the pager therefore I wrote my answer on this on page (Viewpager in Android to switch between days endlessly)

Using AngularJS
1.6.9+
There is one more incident, it also happen when you declare variable name different of module name.
var indexPageApp = angular.module('indexApp', []);
to get rid of this error,
Error: [$injector:nomod] Module 'indexPageApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
change the module name similar to var declared name or vice versa -
var indexPageApp = angular.module('indexPageApp', []);
First you need to wrap your code in a Label
or Literal
control so that you can reference it properly. What's happening is that there's no way for the system to keep track of it, because there's no control associated with the text. It's the control's responsibility to add its contents to viewstate.
You need to use gridView.FindControl("controlName"); to get the control in the row. From there you can get at its properties including Text
.
You can also get at the DataItem property of the Row in question and cast it to the appropriate type and extract the information directly.
You do not need as.vector()
, but you do need correct indexing: avector <- aframe[ , "a2"]
The one other thing to be aware of is the drop=FALSE
option to [
:
R> aframe <- data.frame(a1=c1:5, a2=6:10, a3=11:15)
R> aframe
a1 a2 a3

2 2 7 12
3 3 8 13
4 4 9 14
5 5 10 15
R> avector <- aframe[, "a2"]
R> avector
[1] 6 7 8 9 10
R> avector <- aframe[, "a2", drop=FALSE]
R> avector

Depending on the hibernate flush mode that you are using (AUTO
is the default) save
may or may not write your changes to the DB straight away. When you call saveAndFlush
you are enforcing the synchronization of your model state with the DB.
If you use flush mode AUTO and you are using your application to first save and then select the data again, you will not see a difference in bahvior between save()
and saveAndFlush()
because the select triggers a flush first. See the documention.
Why not implement your own replace?
void myReplace(std::string& str,
const std::string& oldStr,
const std::string& newStr)
{
std::string::size_type pos = 0u;
while((pos = str.find(oldStr, pos)) != std::string::npos){
str.replace(pos, oldStr.length(), newStr);
pos += newStr.length();
}
}
Here's a working solution for a Sybase database

t.table_name,
c.column_name
from
systab as t key join systabcol as c
where
c.column_name = 'MyColumnName'
If you are using Node.js for development, it is recommended to use a package called Validator. It includes all the regexes required to validate different versions of UUID's plus you get various other functions for validation.
Here is the npm link: Validator

v.isUUID(a)
true
v.isUUID('abc')
false
v.isNull(a)
false

In your example, because you use CurrentDB to execute your INSERT you've made it harder for yourself. Instead, this will work:
Dim query As String
Dim newRow As Long ' note change of data type
Dim db As DAO.Database
query = "INSERT INTO InvoiceNumbers (date) VALUES (" & NOW() & ");"
Set db = CurrentDB
db.Execute(query)
newRow = db.OpenRecordset("SELECT @@IDENTITY")(0)
Set db = Nothing
I used to do INSERTs by opening an AddOnly
recordset and picking up the ID from there, but this here is a lot more efficient. And note that it doesn't require ADO
.
Google gives a breakdown of these fields in the Evaluating network performance section of their DevTools documentation.
Stalled/Blocking
Time the request spent waiting before it could be sent. This time is inclusive of any time spent in proxy negotiation. Additionally, this time will include when the browser is waiting for an already established connection to become available for re-use, obeying Chrome's maximum six TCP connection per origin rule.
(If you forget, Chrome has an "Explanation" link in the hover tooltip and under the "Timing" panel.)
Basically, the primary reason you will see this is because Chrome will only download 6 files per-server at a time and other requests will be stalled until a connection slot becomes available.
This isn't necessarily something that needs fixing, but one way to avoid the stalled state would be to distribute the files across multiple domain names and/or servers, keeping CORS in mind if applicable to your needs, however HTTP2 is probably a better option going forward. Resource bundling (like JS and CSS concatenation) can also help to reduce amount of stalled connections.
The answer given by P????? creates a nullable bool, not a bool, which may be fine for you. For example in C# it would create: bool? AdminApproved
not bool AdminApproved
.
If you need to create a bool (defaulting to false):
ALTER TABLE person
ADD AdminApproved BIT
DEFAULT 0 NOT NULL;
On jQuery for designers there's a well written post about this, this is the jQuery snippet that does the magic. just replace #comment with the selector of the div that you want to float.
Note: To see the whole article go here: http://jqueryfordesigners.com/fixed-floating-elements/
$(document).ready(function () {
var $obj = $('#comment');
var top = $obj.offset().top - parseFloat($obj.css('marginTop').replace(/auto/, 0));
$(window).scroll(function (event) {
// what the y position of the scroll is
var y = $(this).scrollTop();
// whether that's below the form
if (y >= top) {
// if so, ad the fixed class
$obj.addClass('fixed');
} else {
// otherwise remove it
$obj.removeClass('fixed');
}
});
});
I think is more robust to use regular expressions:
import re
for i, line in enumerate(content):
print line if not (re.match('\r?\n', line)) else pass
This would match in Windows/unix. In addition if you are not sure about lines containing only space char you could use '\s*\r?\n'
as expression
The “user is currently connected to it” might be SQL Server Management Studio window itself. Try selecting the master database and running the ALTER
query again.
If you would like to do it in a more functional way (immutability) I would return a new date object instead of modifying the existing and I wouldn't alter the prototype but create a standalone function. Here is the example:
//JS
function addHoursToDate(date, hours) {
return new Date(new Date(date).setHours(date.getHours() + hours));
}
//TS
function addHoursToDate(date: Date, hours: number): Date {
return new Date(new Date(date).setHours(date.getHours() + hours));
}
let myDate = new Date();
console.log(myDate)
console.log(addHoursToDate(myDate,2))
_x000D_
Heres another approach.
HTML:
<input type='text' id="pointspossible" class="clsInput" />
<input type='text' id="pointsgiven" class="clsInput" />
<button id="btnCalculate">Calculate</button>
<input type='text' id="pointsperc" disabled/>
JS Code:
function isNumeric(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
$('#btnCalculate').on('click', function() {
var a = $('#pointspossible').val().replace(/ +/g, "");
var b = $('#pointsgiven').val().replace(/ +/g, "");
var perc = "0";
if (a.length > 0 && b.length > 0) {
if (isNumeric(a) && isNumeric(b)) {
perc = a / b * 100;
}
}
$('#pointsperc').val(perc).toFixed(3);
});

Automatic garbage collection is the process of looking at heap memory, identifying which objects are in use and which are not, and deleting the unused objects. An in use object, or a referenced object, means that some part of your program still maintains a pointer to that object. An unused object, or unreferenced object, is no longer referenced by any part of your program. So the memory used by an unreferenced object can be reclaimed.
In a programming language like C, allocating and deallocating memory is a manual process. In Java, process of deallocating memory is handled automatically by the garbage collector. Please check the link for a better understanding. http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/gc01/index.html
On Mac OS X, the way I enabled Jenkins to pull from my (private) Github repo is:
First, ensure that your user owns the Jenkins directory
sudo chown -R me:me /Users/Shared/Jenkins
Then edit the LaunchDaemon plist for Jenkins (at /Library/LaunchDaemons/org.jenkins-ci.plist) so that your user is the GroupName and the UserName:
<key>GroupName</key>
<string>me</string>
...
<key>UserName</key>
<string>me</string>
Then reload Jenkins:
sudo launchctl unload -w /Library/LaunchDaemons/org.jenkins-ci.plist
sudo launchctl load -w /Library/LaunchDaemons/org.jenkins-ci.plist
Then Jenkins, since it's running as you, has access to your ~/.ssh directory which has your keys.

Apple released code at WWDC as a category on UIImage that includes this functionality, if you have a developer account you can grab the UIImage category (and the rest of the sample code) by going to this link: https://developer.apple.com/wwdc/schedule/ and browsing for section 226 and clicking on details. I haven't played around with it yet but I think the effect will be a lot slower on iOS 6, there are some enhancements to iOS 7 that make grabbing the initial screen shot that is used as input to the blur a lot faster.

Random r = new Random();
int i1 = r.nextInt(80 - 65) + 65;
This gives a random integer between 65 (inclusive) and 80 (exclusive), one of 65,66,...,78,79
.

Don't know if it's the best way but I'd do this:
=A1 & TEXT(A2,"mm/dd/yyyy")
That should format your date into your desired string.
Edit: That funny number you saw is the number of days between December 31st 1899 and your date. That's how Excel stores dates.
Good day,
I know I am late to this party, but let me show you my answer.

I suggest looking into background-size
options to adjust the image size.
Instead of having the image in the page if you have it set as a background image you can set:
background-size: contain
or
background-size: cover
These options take into account both the height and width when scaling the image. This will work in IE9 and all other recent browsers.
Here is my solution:
DataTable datatable = (DataTable)dataset.datatablename;
In [92]: (myseries==7).argmax()
Out[92]: 3
This works if you know 7 is there in advance. You can check this with (myseries==7).any()
Another approach (very similar to the first answer) that also accounts for multiple 7's (or none) is
In [122]: myseries = pd.Series([1,7,0,7,5], index=['a','b','c','d','e'])
In [123]: list(myseries[myseries==7].index)
Out[123]: ['b', 'd']
You can enable Jetifier
on your project, which will basically exchange the Android Support Library
dependencies in your project dependencies with AndroidX
-ones. (e.g. Your Lottie dependencies will be changed from Support to AnroidX)
From the Android Studio Documentation (https://developer.android.com/studio/preview/features/):
The Android Gradle plugin provides the following global flags that you can set in your gradle.properties file:
- android.useAndroidX: When set to true, this flag indicates that you want to start using AndroidX from now on. If the flag is absent, Android Studio behaves as if the flag were set to false.
- android.enableJetifier: When set to true, this flag indicates that you want to have tool support (from the Android Gradle plugin) to automatically convert existing third-party libraries as if they were written for AndroidX. If the flag is absent, Android Studio behaves as if the flag were set to false.
Precondition for Jetifier:
Android Studio 3.2
To enable jetifier, add those two lines to your gradle.properties
file:
android.useAndroidX=true
android.enableJetifier=true
Finally, please check the release notes of AndroidX, because jetifier
has still some problems with some libraries (e.g. Dagger Android): https://developer.android.com/topic/libraries/support-library/androidx-rn
A more "duck typing" way is to use respond_to?
this way "integer-like" or "string-like" classes can also be used
if(s.respond_to?(:match) && s.match(".com")){
puts "It's a .com"
else
puts "It's not"
end
What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.
I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)
try
var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
$.ajax({

success: function(data)
{
id = data[0];
vname = data[1];
printWithAjax();
}
});
}//end of the for statement
}//end of ajax call function
The link below will demonstrate how I accomplished this. Not very hard - just have to use some clever front-end dev!!

If you want to use the --prefix
or -p
arguments, but want to avoid having to use the environment's full path to activate it, you need to edit the .condarc
config file before you create the environment.
The .condarc
file is in the home directory; C:\Users\<user>
on Windows. Edit the values under the envs_dirs
key to include the custom path for your environment. Assuming the custom path is D:\envs
, the file should end up looking something like this:
ssl_verify: true
channels:
- defaults
envs_dirs:
- C:\Users\<user>\Anaconda3\envs
- D:\envs
Then, when you create a new environment on that path, its name will appear along with the path when you run conda env list
, and you should be able to activate it using only the name, and not the full path.
In summary, if you edit .condarc
to include D:\envs
, and then run conda env create -p D:\envs\myenv python=x.x
, then activate myenv
(or source activate myenv
on Linux) should work.
Hope that helps!
P.S. I stumbled upon this through trial and error. I think what happens is when you edit the envs_dirs
key, conda updates ~\.conda\environments.txt
to include the environments found in all the directories specified under the envs_dirs
, so they can be accessed without using absolute paths.
The extension is available but not installed in this database.

Using 'sqlparse' library we can format the sqls.
>>> import sqlparse
>>> raw = 'select * from foo; select * from bar;'
>>> print(sqlparse.format(raw, reindent=True, keyword_case='upper'))
SELECT *
FROM foo;
SELECT *
FROM bar;
const el = document.getElementById("editable");
el.focus()
let char = 1, sel; // character at which to place caret
if (document.selection) {
sel = document.selection.createRange();
sel.moveStart('character', char);
sel.select();
}
else {
sel = window.getSelection();
sel.collapse(el.lastChild, char);
}
Pay attention, if you use cv.CV_THRESH_BINARY
means every pixel greater than threshold becomes the maxValue (in your case 255), otherwise the value is 0. Obviously if your threshold is 0 everything becomes white (maxValue = 255) and if the value is 255 everything becomes black (i.e. 0).
If you don't want to work out a threshold, you can use the Otsu's method. But this algorithm only works with 8bit images in the implementation of OpenCV. If your image is 8bit use the algorithm like this:
cv.Threshold(im_gray_mat, im_bw_mat, threshold, 255, cv.CV_THRESH_BINARY | cv.CV_THRESH_OTSU);
No matter the value of threshold if you have a 8bit image.
Not sure how useful this is, but I ended up here from looking for a solution on Netezza SQL and couldn't find one on stack overflow.
For IBM netezza you would use something (for week start mon, week end sun) like:
select next_day (WeddingDate, 'SUN') -6 as WeekStart,
next_day (WeddingDate, 'SUN') as WeekEnd
It looks like you are calling next even if the scanner no longer has a next element to provide... throwing the exception.
while(!file.next().equals(treasure)){
file.next();
}
Should be something like
boolean foundTreasure = false;
while(file.hasNext()){
if(file.next().equals(treasure)){
foundTreasure = true;
break; // found treasure, if you need to use it, assign to variable beforehand
}
}
// out here, either we never found treasure at all, or the last element we looked as was treasure... act accordingly
I suggest you check out chunked
and disk.frame
. They both have functions for reading in CSVs chunk-by-chunk.
In particular, disk.frame::csv_to_disk.frame
may be the function you are after?
What should I do to prepare my website for https. (Do I need to alter the code / Config)
You should keep best practices for secure coding in mind (here is a good intro: http://www.owasp.org/index.php/Secure_Coding_Principles ), otherwise all you need is a correctly set up SSL certificate.
Is SSL and https one and the same..
Pretty much, yes.
Do I need to apply with someone to get some license or something.
You can buy an SSL certificate from a certificate authority or use a self-signed certificate. The ones you can purchase vary wildly in price - from $10 to hundreds of dollars a year. You would need one of those if you set up an online shop, for example. Self-signed certificates are a viable option for an internal application. You can also use one of those for development. Here's a good tutorial on how to set up a self-signed certificate for IIS: Enabling SSL on IIS 7.0 Using Self-Signed Certificates
Do I need to make all my pages secured or only the login page..
Use HTTPS for everything, not just the initial user login. It's not going to be too much of an overhead and it will mean the data that the users send/receive from your remotely hosted application cannot be read by outside parties if it is intercepted. Even Gmail now turns on HTTPS by default.
switch(message)
{
case "test":
Console.WriteLine("yes");
break;
default:
if (Contains("test2")) {
Console.WriteLine("yes for test2");
}
break;
}
And even simpler using IN:
SELECT ads.*, location.county
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)
To insert the default values you should omit them something like this :
Insert into Table (Field2) values(5)
All other fields will have null or their default values if it has defined.
//selected date from calender
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy"); //Date and time
String currentDate = sdf.format(myCalendar.getTime());
//selcted_day name
SimpleDateFormat sdf_ = new SimpleDateFormat("EEEE");
String dayofweek=sdf_.format(myCalendar.getTime());
current_date.setText(currentDate);
lbl_current_date.setText(dayofweek);
Log.e("dayname", dayofweek);
So, you want to exclude firstName
and country.name
. Here is what your ExclusionStrategy
should look like
public class TestExclStrat implements ExclusionStrategy {
public boolean shouldSkipClass(Class<?> arg0) {
return false;
}
public boolean shouldSkipField(FieldAttributes f) {
return (f.getDeclaringClass() == Student.class && f.getName().equals("firstName"))||
(f.getDeclaringClass() == Country.class && f.getName().equals("name"));
}
}
If you see closely it returns true
for Student.firstName
and Country.name
, which is what you want to exclude.
You need to apply this ExclusionStrategy
like this,
Gson gson = new GsonBuilder()
.setExclusionStrategies(new TestExclStrat())
//.serializeNulls() <-- uncomment to serialize NULL fields as well
.create();
Student src = new Student();
String json = gson.toJson(src);
System.out.println(json);
This returns:
{ "middleName": "J.", "initials": "P.F", "lastName": "Fry", "country": { "id": 91}}
I assume the country object is initialized with id = 91L
in student class.
You may get fancy. For example, you do not want to serialize any field that contains "name" string in its name. Do this:
public boolean shouldSkipField(FieldAttributes f) {
return f.getName().toLowerCase().contains("name");
}
This will return:
{ "initials": "P.F", "country": { "id": 91 }}
EDIT: Added more info as requested.
This ExclusionStrategy
will do the thing, but you need to pass "Fully Qualified Field Name". See below:
public class TestExclStrat implements ExclusionStrategy {
private Class<?> c;
private String fieldName;
public TestExclStrat(String fqfn) throws SecurityException, NoSuchFieldException, ClassNotFoundException
{
this.c = Class.forName(fqfn.substring(0, fqfn.lastIndexOf(".")));
this.fieldName = fqfn.substring(fqfn.lastIndexOf(".")+1);
}
public boolean shouldSkipClass(Class<?> arg0) {
return false;
}
public boolean shouldSkipField(FieldAttributes f) {
return (f.getDeclaringClass() == c && f.getName().equals(fieldName));
}
}
Here is how we can use it generically.
Gson gson = new GsonBuilder()
.setExclusionStrategies(new TestExclStrat("in.naishe.test.Country.name"))
//.serializeNulls()
.create();
Student src = new Student();
String json = gson.toJson(src);
System.out.println(json);
It returns:
{ "firstName": "Philip" , "middleName": "J.", "initials": "P.F", "lastName": "Fry", "country": { "id": 91 }}
