Using Spark Sql 2.4.0 you can do that:
spark.sql("SELECT STRING(NULLIF(column,'')) as column_string")
Suppose you have following lines of code
MyUrl = "www.google.com" #Your url goes here
urllib.urlretrieve(MyUrl)
If you are receiving following error message
AttributeError: module 'urllib' has no attribute 'urlretrieve'
Then you should try following code to fix the issue:
import urllib.request
MyUrl = "www.google.com" #Your url goes here
urllib.request.urlretrieve(MyUrl)
var dn = await Task.WhenAll<dynamic>(FeedCat(),SellHouse(),BuyCar());
if you want to access Cat, you do this:
var ct = (Cat)dn[0];
This is very simple to do and very useful to use, there is no need to go after a complex solution.
I had the similar issue for my Spring Boot - Gradle application running on Eclipse Luna. I could resolve it by manually adding an entry in my project's .classpath
<classpathentry sourcepath="C:/Users/<username>/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-simple/1.7.7/3150039466ad03e6ef1c7ec1c2cbb0d96710cf64/slf4j-simple-1.7.7-sources.jar" kind="lib" path="C:/Users/<username>/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-simple/1.7.7/8095d0b9f7e0a9cd79a663c740e0f8fb31d0e2c8/slf4j-simple-1.7.7.jar"/>
Idea is to follow this solution. But how to implement is dependent on case to case. One way of fixing is the one that I used above.
Hope this helps.
var d = new Date();
var v = new Date();
v.setMinutes(d.getMinutes()+20);
Hive Partitioning:
Partition divides large amount of data into multiple slices based on value of a table column(s).
Assume that you are storing information of people in entire world spread across 196+ countries spanning around 500 crores of entries. If you want to query people from a particular country (Vatican city), in absence of partitioning, you have to scan all 500 crores of entries even to fetch thousand entries of a country. If you partition the table based on country, you can fine tune querying process by just checking the data for only one country partition. Hive partition creates a separate directory for a column(s) value.
Pros:
Cons:
Hive Bucketing:
Bucketing decomposes data into more manageable or equal parts.
With partitioning, there is a possibility that you can create multiple small partitions based on column values. If you go for bucketing, you are restricting number of buckets to store the data. This number is defined during table creation scripts.
Pros
Cons
this might be a solution, i have done something similar but this one does not seem to work for example if the necessary function requires administrator privileges it should ask you to restart it as admin.
@echo off
mkdir C:\Users\cmdfolder
if echo=="Access is denied." (goto :1A) else (goto :A4)
:A1
cls
color 0d
echo restart this program as administator
:A4
pause
If you have a class for each of your input box, then you can do it as
var checked = []
$('input.Booking').each(function ()
{
checked.push($(this).val());
});
Small sample test.cmd

@echo off
powershell /nologo /noprofile /command ^

Another alternative is to do right click on the chrome icon and then go to shortcut tab (according to windows 10). You will see there "Target", copy the path and remove "chrome.exe".
Using MacPorts you can install the client with:
sudo port install mysql57
You also need to select the installed version as your mysql
sudo port select mysql mysql57
The server is only installed if you append -server
to the package name (e.g. mysql57-server
)
From the matplotlib docs on scatter 1:
cmap is only used if c is an array of floats
So colorlist needs to be a list of floats rather than a list of tuples as you have it now. plt.colorbar() wants a mappable object, like the CircleCollection that plt.scatter() returns. vmin and vmax can then control the limits of your colorbar. Things outside vmin/vmax get the colors of the endpoints.
How does this work for you?
import matplotlib.pyplot as plt
cm = plt.cm.get_cmap('RdYlBu')
xy = range(20)
z = xy
sc = plt.scatter(xy, xy, c=z, vmin=0, vmax=20, s=35, cmap=cm)
plt.colorbar(sc)
plt.show()
You can install via apt-get
:
sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install oracle-java11-installer
After, do not forget to check the version:

There's a much, much easier way. Do this:
MyComponent.vue
<template>
stuff here
</template>
<script>
import $ from 'jquery';
import 'selectize';
$(function() {
// use jquery
$('body').css('background-color', 'orange');
// use selectize, s jquery plugin
$('#myselect').selectize( options go here );
});
</script>
Make sure JQuery is installed first with npm install jquery
. Do the same with your plugin.
Uncomment the line extension=php_mysql.dll
in your "php.ini" file and restart Apache.
Additionally, "libmysql.dll" file must be available to Apache, i.e., it must be either in available in Windows systems PATH or in Apache working directory.
See more about installing MySQL extension in manual.
P.S. I would advise to consider MySQL extension as deprecated and to use MySQLi or even PDO for working with databases (I prefer PDO).
You want to use transform
this will return a Series with the index aligned to the df so you can then add it as a new column:
In [74]:
df = pd.DataFrame({'Date': ['2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05', '2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05'], 'Sym': ['aapl', 'aapl', 'aapl', 'aapl', 'aaww', 'aaww', 'aaww', 'aaww'], 'Data2': [11, 8, 10, 15, 110, 60, 100, 40],'Data3': [5, 8, 6, 1, 50, 100, 60, 120]})
?
df['Data4'] = df['Data3'].groupby(df['Date']).transform('sum')
df
Out[74]:
Data2 Data3 Date Sym Data4
0 11 5 2015-05-08 aapl 55
1 8 8 2015-05-07 aapl 108
2 10 6 2015-05-06 aapl 66
3 15 1 2015-05-05 aapl 121
4 110 50 2015-05-08 aaww 55
5 60 100 2015-05-07 aaww 108
6 100 60 2015-05-06 aaww 66
7 40 120 2015-05-05 aaww 121
In fact, your query is right except for the typo: your filter is excluding all records: you should change the <=
for >=
and vice versa:
qry = DBSession.query(User).filter(
and_(User.birthday <= '1988-01-17', User.birthday >= '1985-01-17'))
# or same:
qry = DBSession.query(User).filter(User.birthday <= '1988-01-17').\
filter(User.birthday >= '1985-01-17')
Also you can use between
:
qry = DBSession.query(User).filter(User.birthday.between('1985-01-17', '1988-01-17'))
In an Excel pivot table, you are correct that a filter only allows values that are explicitly selected. If the filter field is placed on the pivot table rows or columns, however, you get a much wider set of Label Filter conditions, including Greater Than. If you did that in your case, then the added benefit would be that the various probability levels that match your condition are shown in the body of the table.
The platform is not specified, but in C# (.NET) it would be:
Regular expression (presumes the multiline option - the example below uses it):
[ \t]+(\r?$)
Replacement:
$1
For an explanation of "\r?$", see Regular Expression Options, Multiline Mode (MSDN).
This will remove all trailing spaces and all trailing TABs in all lines:
string inputText = " Hello, World! \r\n" +
" Some other line\r\n" +
" The last line ";
string cleanedUpText = Regex.Replace(inputText,
@"[ \t]+(\r?$)", @"$1",
RegexOptions.Multiline);
Based on @ofer.sheffer answer this command will mass rename and append the current date to the filename. ie "file.txt" becomes "20180329 - file.txt" for all files in the current folder
for %a in (*.*) do ren "%a" "%date:~-4,4%%date:~-7,2%%date:~-10,2% - %a"
I resolved the same issue by running Workbench as administrator.
...I guess it's because of restrictions on company computers, in my case...
just nearly the same with the first answer about, but some more advantage.
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.html -f

RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
Just add up if you have a other file-extension in your sites
fs.exists
has been deprecated since 1.0.0. You can use fs.stat
instead of that.
var fs = require('fs');
fs.stat(path, (err, stats) => {
if ( !stats.isFile(filename) ) { // do this
}
else { // do this
}});
Here is the link for the documentation fs.stats
I'd recommend using Promise.all as mentioned above, but if you really feel like avoiding that approach, you can do a for or any other loop:
const arr = [1,2,3,4,5];
let resultingArr = [];
for (let i in arr){
await callAsynchronousOperation(i);
resultingArr.push(i + 1)
}
You can round the result and use string.Format
to set the precision like this:
decimal pay = 200.5555m;
pay = Math.Round(pay + bonus, 2);
string payAsString = string.Format("{0:0.00}", pay);
The best option I've seen is the following extension method:
public static Task ForEachAsync<T>(this IEnumerable<T> sequence, Func<T, Task> action) {
return Task.WhenAll(sequence.Select(action));
}
Call it like this:
await sequence.ForEachAsync(item => item.SomethingAsync(blah));
Or with an async lambda:
await sequence.ForEachAsync(async item => {
var more = await GetMoreAsync(item);
await more.FrobbleAsync();
});
There is no way to convert a VBScript (.vbs file) into an executable (.exe file) because VBScript is not a compiled language. The process of converting source code into native executable code is called "compilation", and it's not supported by scripting languages like VBScript.
Certainly you can add your script to a self-extracting archive using something like WinZip, but all that will do is compress it. It's doubtful that the file size will shrink noticeably, and since it's a plain-text file to begin with, it's really not necessary to compress it at all. The only purpose of a self-extracting archive is that decompression software (like WinZip) is not required on the end user's computer to be able to extract or "decompress" the file. If it isn't compressed in the first place, this is a moot point.
Alternatively, as you mentioned, there are ways to wrap VBScript code files in a standalone executable file, but these are just wrappers that automatically execute the script (in its current, uncompiled state) when the user double-clicks on the .exe file. I suppose that can have its benefits, but it doesn't sound like what you're looking for.
In order to truly convert your VBScript into an executable file, you're going to have to rewrite it in another language that can be compiled. Visual Basic 6 (the latest version of VB, before the .NET Framework was introduced) is extremely similar in syntax to VBScript, but does support compiling to native code. If you move your VBScript code to VB 6, you can compile it into a native executable. Running the .exe file will require that the user has the VB 6 Run-time libraries installed, but they come built into most versions of Windows that are found now in the wild.
Alternatively, you could go ahead and make the jump to Visual Basic .NET, which remains somewhat similar in syntax to VB 6 and VBScript (although it won't be anywhere near a cut-and-paste migration). VB.NET programs will also compile to an .exe file, but they require the .NET Framework runtime to be installed on the user's computer. Fortunately, this has also become commonplace, and it can be easily redistributed if your users don't happen to have it. You mentioned going this route in your question (porting your current script in to VB Express 2008, which uses VB.NET), but that you were getting a lot of errors. That's what I mean about it being far from a cut-and-paste migration. There are some huge differences between VB 6/VBScript and VB.NET, despite some superficial syntactical similarities. If you want help migrating over your VBScript, you could post a question here on Stack Overflow. Ultimately, this is probably the best way to do what you want, but I can't promise you that it will be simple.
You can do in a very simple way. The idea is to place a Label in the same place as your textbox. Your Label will be visible if textbox has no text and hasn't the focus.
<Label Name="PalceHolder" HorizontalAlignment="Left" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="40" VerticalAlignment="Top" Width="239" FontStyle="Italic" Foreground="BurlyWood">PlaceHolder Text Here
<Label.Style>
<Style TargetType="{x:Type Label}">
<Setter Property="Visibility" Value="Hidden"/>
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding ="{Binding ElementName=PalceHolder, Path=Text.Length}" Value="0"/>
<Condition Binding ="{Binding ElementName=PalceHolder, Path=IsFocused}" Value="False"/>
</MultiDataTrigger.Conditions>
<Setter Property="Visibility" Value="Visible"/>
</MultiDataTrigger>
</Style.Triggers>
</Style>
</Label.Style>
</Label>
<TextBox Background="Transparent" Name="TextBox1" HorizontalAlignment="Left" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="40"TextWrapping="Wrap" Text="{Binding InputText,Mode=TwoWay}" VerticalAlignment="Top" Width="239" />
Bonus:If you want to have default value for your textBox, be sure after to set it when submitting data (for example:"InputText"="PlaceHolder Text Here" if empty).
The above method for Visual Studio didn't seem to apply to Visual Studio 2013, but I was able to find the described checkbox using the Project Menu and selecting my project (probably the last item on the submenu) to get to the dialog with the checkbox (on the Build tab).
One of the big uses for function pointers in C is to call a function selected at run-time. For example, the C run-time library has two routines, qsort
and bsearch
, which take a pointer to a function that is called to compare two items being sorted; this allows you to sort or search, respectively, anything, based on any criteria you wish to use.
A very basic example, if there is one function called print(int x, int y)
which in turn may require to call a function (either add()
or sub()
, which are of the same type) then what we will do, we will add one function pointer argument to the print()
function as shown below:
#include <stdio.h>
int add()
{
return (100+10);
}
int sub()
{
return (100-10);
}
void print(int x, int y, int (*func)())
{
printf("value is: %d\n", (x+y+(*func)()));
}
int main()
{
int x=100, y=200;
print(x,y,add);
print(x,y,sub);
return 0;
}
The output is:
value is: 410
value is: 390
It is a good approach. I use it myself as well. I would only suggest to override onCreate
to set the singleton instead of using a constructor.
And since you mentioned SQLiteOpenHelper
: In onCreate ()
you can open the database as well.
Personally I think the documentation got it wrong in saying that There is normally no need to subclass Application. I think the opposite is true: You should always subclass Application.
When I find myself thinking about using Manager
or Helper
in a class name, I consider it a code smell that means I haven't found the right abstraction yet and/or I'm violating the single responsibility principle, so refactoring and putting more effort into design often makes naming much easier.
But even well-designed classes don't (always) name themselves, and your choices partly depend on whether you're creating business model classes or technical infrastructure classes.
Business model classes can be hard, because they're different for every domain. There are some terms I use a lot, like Policy
for strategy classes within a domain (e.g., LateRentalPolicy
), but these usually flow from trying to create a "ubiquitous language" that you can share with business users, designing and naming classes so they model real-world ideas, objects, actions, and events.
Technical infrastructure classes are a bit easier, because they describe domains we know really well. I prefer to incorporate design pattern names into the class names, like InsertUserCommand,
CustomerRepository,
or SapAdapter.
I understand the concern about communicating implementation instead of intent, but design patterns marry these two aspects of class design - at least when you're dealing with infrastructure, where you want the implementation design to be transparent even while you're hiding the details.
If someone says you can't because only Windows can control the non-client area, they're wrong!
That's just a half-truth because Windows lets you specify the dimensions of the non-client area. The fact is, this is possible only throughout the Windows' kernel methods, and you're in .NET, not C/C++. Anyway, don't worry! P/Invoke was meant just for such things! Indeed, the whole of the Windows Form UI and Console application Std-I/O methods are offered using system calls. Hence, you'd have only to perform the right system calls to set the non-client area up, as documented in MSDN.
However, this is a really hard solution I came up with a lot of time ago. Luckily, as of .NET 4.5, you can use the WindowChrome
class to adjust the non-client area like you want. Here you can get to start with.
In order to make things simpler and cleaner, I'll redirect you here, a guide to change the window border dimensions to whatever you want. By setting it to 0, you'll be able to implement your custom window border in place of the system's one.
I'm sorry for not posting a clear example, but later I will for sure.
Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -
sign before value
:
ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) +
geom_bar(stat = "identity")
which gives:
Used data:
corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
value = c(7L, 75L, 70L, 5L, 10L, 47L)),
class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))
Here is an example of request execution process in its simplest form:
CloseableHttpClient httpclient = HttpClients.createDefault(); HttpGet httpget = new HttpGet("http://localhost/"); CloseableHttpResponse response = httpclient.execute(httpget); try { //do something } finally { response.close(); }
HttpClient resource deallocation: When an instance CloseableHttpClient is no longer needed and is about to go out of scope the connection manager associated with it must be shut down by calling the CloseableHttpClient#close() method.
CloseableHttpClient httpclient = HttpClients.createDefault(); try { //do something } finally { httpclient.close(); }
see the Reference to learn fundamentals.
@Scadge Since Java 7, Use of try-with-resources statement ensures that each resource is closed at the end of the statement. It can be used both for the client and for each response
try(CloseableHttpClient httpclient = HttpClients.createDefault()){
// e.g. do this many times
try (CloseableHttpResponse response = httpclient.execute(httpget)) {
//do something
}
//do something else with httpclient here
}
Nice solution from Codeaddict. I took the liberty of implementing a version of it in Ruby:
def find_sum(arr,sum)
result ={}
h = Hash[arr.map {|i| [i,i]}]
arr.each { |l| result[l] = sum-l if h[sum-l] && !result[sum-l] }
result
end
To allow duplicate pairs (1,5), (5,1) we just have to remove the && !result[sum-l]
instruction
You can change this using xml
app:tabIndicatorColor="#fff"
To be more clear, I will begin at the beginning.
I will rely on the sample code found in https://github.com/ExcelDataReader/ExcelDataReader, but with some modifications to avoid inconveniences.
The following code detects the file format, either xls or xlsx.
FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader;
//1. Reading Excel file
if (Path.GetExtension(filePath).ToUpper() == ".XLS")
{
//1.1 Reading from a binary Excel file ('97-2003 format; *.xls)
excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
}
else
{
//1.2 Reading from a OpenXml Excel file (2007 format; *.xlsx)
excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
}
//2. DataSet - The result of each spreadsheet will be created in the result.Tables
DataSet result = excelReader.AsDataSet();
//3. DataSet - Create column names from first row
excelReader.IsFirstRowAsColumnNames = false;
Now we can access the file contents in a more convenient way. I use DataTable for this. The following is an example to access a specific cell, and print its value in the console:
DataTable dt = result.Tables[0];
Console.WriteLine(dt.Rows[rowPosition][columnPosition]);
If you do not want to do a DataTable, you can do the same as follows:
Console.WriteLine(result.Tables[0].Rows[rowPosition][columnPosition]);
It is important not try to read beyond the limits of the table, for this you can see the number of rows and columns as follows:
Console.WriteLine(result.Tables[0].Rows.Count);
Console.WriteLine(result.Tables[0].Columns.Count);
Finally, when you're done, you should close the reader and free resources:
//5. Free resources (IExcelDataReader is IDisposable)
excelReader.Close();
I hope you find it useful.
(I understand that the question is old, but I make this contribution to enhance the knowledge base, because there is little material about particular implementations of this library).
Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:
<script type="text/javascript">
$(function() {
$('form').submit(function(){
$.post('http://example.com/upload', function() {
window.location = 'http://google.com';
});
return false;
});
});
</script>
git config --global core.editor "'C:/Program Files/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
Or, for 64-bit Windows and a 32-bit install of Notepad++:
git config --global core.editor "'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
Or, the following can be issued on the command line on either 32-bit or 64-bit Windows. It will pull the location of notepad++.exe from the registry and configure git to use it automatically:
FOR /F "usebackq tokens=2*" %A IN (`REG QUERY "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App Paths\notepad++.exe" /ve`) DO git config --global core.editor "'%B' -multiInst -notabbar -nosession -noPlugin"
If you wish to place the above from a .BAT or .CMD file, you must replace %A with %%A and %B with %%B
White Box Testing equals Software Unit Test. The developer or a development level tester (e.g. another developer) ensures that the code he has written is working properly according to the detailed level requirements before integrating it in the system.
Black Box Testing equals Integration Testing. The tester ensures that the system works according to the requirements on a functional level.
Both test approaches are equally important in my opinion.
A thorough unit test will catch defects in the development stage and not after the software has been integrated into the system. A system level black box test will ensure all software modules behave correctly when integrated together. A unit test in the development stage would not catch these defects since modules are usually developed independent from each other.
Given the following sample
myData <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2), Pulse=20:25)
then
myData$A <-as.factor(myData$A)
myData$B <-as.factor(myData$B)
or you could select your columns altogether and wrap it up nicely:
# select columns
cols <- c("A", "B")
myData[,cols] <- data.frame(apply(myData[cols], 2, as.factor))
levels(myData$A) <- c("long", "short")
levels(myData$B) <- c("1kg", "2kg", "3kg")
To obtain
> myData
A B Pulse
1 long 1kg 20
2 short 2kg 21
3 long 3kg 22
4 short 1kg 23
5 long 2kg 24
6 short 3kg 25
For Laravel 5.3 (and may be in other 5.X versions) put custom pagination code in you view folder.

Update the pagination/default.blade.php however you want
It works in 8.x versions as well.
In Java there isn't Null values for primitive Data types. If you need to check Null use Integer Class instead of primitive type. You don't need to worry about data type difference. Java converts int primitive type data to Integer. When concerning about the memory Integer takes more memory than int. But the difference of memory allocation, nothing to be considered.
In this case you must use Inter instead of int
Try below snippet and see example for more info,
Integer id;
String name;
//Refer this example
Integer val = 0;
`
if (val != null){
System.out.println("value is not null");

Also you can assign Null as below,
val = null;
I think a better approach will be to set app:tabMode="auto"
and app:tabGravity="fill"
because setting tabMode to fixed can make headings congested and cause headings to occupy multiple lines on the other side setting it to scrollable could make them leave spaces at the end in some screen sizes. manually setting tabMode would give a problem when dealing with multiple screen sizes
<com.google.android.material.tabs.TabLayout
android:id="@+id/tabLayout"
app:tabGravity="fill"
android:textAlignment="center"
app:tabMode="auto"
/>
looks like you have maven project and so resources are in classpath by
go for
getClass().getResource("classpath:storedProcedures.sql")
You are using the wrong iteration counter, replace inp.charAt(i)
with inp.charAt(j)
.
In "pure" bash you have many tools for (sub)string manipulation, mainly, but not exclusively in parameter expansion :
${parameter//substring/replacement}
${parameter##remove_matching_prefix}
${parameter%%remove_matching_suffix}
Indexed substring expansion (special behaviours with negative offsets, and, in newer Bashes, negative lengths):
${parameter:offset}
${parameter:offset:length}
${parameter:offset:length}
And of course, the much useful expansions that operate on whether the parameter is null:
${parameter:+use this if param is NOT null}
${parameter:-use this if param is null}
${parameter:=use this and assign to param if param is null}
${parameter:?show this error if param is null}
They have more tweakable behaviours than those listed, and as I said, there are other ways to manipulate strings (a common one being $(command substitution)
combined with sed or any other external filter). But, they are so easily found by typing man bash
that I don't feel it merits to further extend this post.
This worked for me to return an array of strings from my config:
var allowedMethods = Configuration.GetSection("AppSettings:CORS-Settings:Allow-Methods")
.Get<string[]>();
My configuration section looks like this:
"AppSettings": {
"CORS-Settings": {
"Allow-Origins": [ "http://localhost:8000" ],
"Allow-Methods": [ "OPTIONS","GET","HEAD","POST","PUT","DELETE" ]
}
}
check your casing, the name is typically stored in upper case
SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;
Server restart helped, I'm able to connect to server again.
The OA can also be implemented in ES6 as follows
ES6:
const filtered = [1, 2, 3, 4].filter(e => {
return this.indexOf(e) < 0;
},[2, 4]);
String sc1="0.0";
Double s1=Double.parseDouble(sc1.toString());
I had a similar issue. In my case the service would work fine on the developer machine but fail when on a QA machine. It turned out that on the QA machine the application wasn't being run as an administrator and didn't have permission to register the endpoint:
HTTP could not register URL http://+:12345/Foo.svc/]. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details).
Refer here for how to get it working without being an admin user: https://stackoverflow.com/a/885765/38258
You are running your HTML from a different host than the host you are requesting. Because of this, you are getting blocked by the same origin policy.
One way around this is to use JSONP. This allows cross-site requests.
In JSON, you are returned:
{a: 5, b: 6}
In JSONP, the JSON is wrapped in a function call, so it becomes a script, and not an object.
callback({a: 5, b: 6})
You need to edit your REST service to accept a parameter called callback
, and then to use the value of that parameter as the function name. You should also change the content-type
to application/javascript
.
For example: http://localhost:8080/restws/json/product/get?callback=process
should output:
process({a: 5, b: 6})
In your JavaScript, you will need to tell jQuery to use JSONP. To do this, you need to append ?callback=?
to the URL.
$.getJSON("http://localhost:8080/restws/json/product/get?callback=?",
function(data) {
alert(data);
});
If you use $.ajax
, it will auto append the ?callback=?
if you tell it to use jsonp
.
$.ajax({
type: "GET",
dataType: "jsonp",
url: "http://localhost:8080/restws/json/product/get",
success: function(data){
alert(data);
}
});
i'am working with hibernate 5 and postgres, and this worked form me.
@Column(name = "ACCOUNT_TYPE", ***nullable***=false, columnDefinition="varchar2 default 'END_USER'")

Use the map()
function native on JavaScript arrays:
var yourArray = [ {
'id':1,
'name':'john'
},{
'id':2,
'name':'jane'
}........,{
'id':2000,
'name':'zack'
}];
var newArray = yourArray.map( function( el ){
return el.name;
});
You can configure the ObjectMapper as a bean in your Spring xml file. What holds a reference to the ObjectMapper is the MappingJacksonJsonView
class. You then need to attach the view to a ViewResolver.
Something like this should work:
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
<entry key="json" value="application/json" />
<entry key="html" value="text/html" />
</map>
</property>
<property name="viewResolvers">
<list>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</list>
</property>
<property name="defaultViews">
<list>
<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
<property name="prefixJson" value="false" />
<property name="objectMapper" value="customObjectMapper" />
</bean>
</list>
</property>
</bean>
Where customObjectMapper
is defined elsewhere in the xml file. Note that you can directly set Spring property values with the Enums Jackson defines; see this question.
Also, ContentNegotiatingViewResolver probably isn't required, it's just the code I am using in an existing project.
print( "hello " +k+ " " +ln);
where k
and ln
are variables
SGML parsers (or XML parsers in the case of XHTML) can handle —
without having to process the DTD (which doesn't matter to browsers as they just slurp tag soup), while —
is easier for humans to read and write in the source code.
Personally, I would stick to a literal em-dash and ensure that my character encoding settings were consistent.
When you compile the Pattern
Java does some computation to make finding matches in String
s faster. (Builds an in-memory representation of the regex)
If you are going to reuse the Pattern
multiple times you would see a vast performance increase over creating a new Pattern
every time.
In the case of only using the Pattern once, the compiling step just seems like an extra line of code, but, in fact, it can be very helpful in the general case.
You can use the files from debug folder,however if you look at app debug informations with some inspection software,you can clearly see "Symbols File Name" which can reveals not wanted informations in path to the original exe file.
Try this:
word = "habit"
findchar = 'b"
replacechar = ""
charactercount = len(word) - len(replace(word,findchar,replacechar))
I recommend looking at the dataset array.
The dataset array is a data type that ships with Statistics Toolbox. It is specifically designed to store hetrogeneous data in a single container.
The Statistics Toolbox demo page contains a couple vidoes that show some of the dataset array features. The first is titled "An Introduction to Dataset Arrays". The second is titled "An Introduction to Joins".
Connecting to PostgreSQL via SSH Tunneling
In the event that you don't want to open port 5432 to any traffic, or you don't want to configure PostgreSQL to listen to any remote traffic, you can use SSH Tunneling to make a remote connection to the PostgreSQL instance. Here's how:
Looks like it varies depending on what compiler you're using (blech):
%zu
(or %zx
, or %zd
but that displays it as though it were signed, etc.)%Iu
(or %Ix
, or %Id
but again that's signed, etc.) — but as of cl v19 (in Visual Studio 2015), Microsoft supports %zu
(see this reply to this comment)...and of course, if you're using C++, you can use cout
instead as suggested by AraK.
Try the following in your CSS stylesheet:
.img-responsive{
max-width: 100%;
height: auto;
}
You are missing the event parameter on your function.
$(document).on("click",".appDetails", function (event) {
alert(event.target.id);
});
put public, protected or private before the $connection.
I think the simplest way is trying to change the system date (that requires admin rights):
date %date%
if errorlevel 1 (
echo You have NOT admin rights
) else (
echo You have admin rights
)
If %date%
variable may include the day of week, just get the date from last part of DATE
command:
for /F "delims=" %%a in ('date ^<NUL') do set "today=%%a" & goto break
:break
for %%a in (%today%) do set "today=%%a"
date %today%
if errorlevel 1 ...
My situation is probably a little different. I am dynamically changing the src of an image via javascript and needed to ensure that the new image is sized proportionally to fit a fixed container (in a photo gallery). I initially just removed the width and height attributes of the image after it is loaded (via the image's load event) and reset these after calculating the preferred dimensions. However, that does not work in Safari and possibly IE (I have not tested it in IE thoroughly, but the image doesn't even show, so...).
Anyway, Safari keeps the dimensions of the previous image so the dimensions are always one image behind. I assume that this has something to do with cache. So the simplest solution is to just clone the image and add it to the DOM (it is important that it be added to the DOM the get the with and height). Give the image a visibility value of hidden (do not use display none because it will not work). After you get the dimensions remove the clone.
Here is my code using jQuery:
// Hack for Safari and others
// clone the image and add it to the DOM
// to get the actual width and height
// of the newly loaded image
var cloned,
o_width,
o_height,
src = 'my_image.jpg',
img = [some existing image object];
$(img)
.load(function()
{
$(this).removeAttr('height').removeAttr('width');
cloned = $(this).clone().css({visibility:'hidden'});
$('body').append(cloned);
o_width = cloned.get(0).width; // I prefer to use native javascript for this
o_height = cloned.get(0).height; // I prefer to use native javascript for this
cloned.remove();
$(this).attr({width:o_width, height:o_height});
})
.attr(src:src);
This solution works in any case.
yum update
helped me out. After I had
wget: symbol lookup error: wget: undefined symbol: psl_latest
It depends on whether default path is set for data and log files or not.
If the path is set explicitly at Properties
=> Database Settings
=> Database default locations
then SQL server stores it at Software\Microsoft\MSSQLServer\MSSQLServer
in DefaultData
and DefaultLog
values.
However, if these parameters aren't set explicitly, SQL server uses Data and Log paths of master database.
Bellow is the script that covers both cases. This is simplified version of the query that SQL Management Studio runs.
Also, note that I use xp_instance_regread
instead of xp_regread
, so this script will work for any instance, default or named.
declare @DefaultData nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', @DefaultData output
declare @DefaultLog nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultLog', @DefaultLog output
declare @DefaultBackup nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'BackupDirectory', @DefaultBackup output
declare @MasterData nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\Parameters', N'SqlArg0', @MasterData output
select @MasterData=substring(@MasterData, 3, 255)
select @MasterData=substring(@MasterData, 1, len(@MasterData) - charindex('\', reverse(@MasterData)))
declare @MasterLog nvarchar(512)
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\Parameters', N'SqlArg2', @MasterLog output
select @MasterLog=substring(@MasterLog, 3, 255)
select @MasterLog=substring(@MasterLog, 1, len(@MasterLog) - charindex('\', reverse(@MasterLog)))
select
isnull(@DefaultData, @MasterData) DefaultData,
isnull(@DefaultLog, @MasterLog) DefaultLog,
isnull(@DefaultBackup, @MasterLog) DefaultBackup
You can achieve the same result by using SMO. Bellow is C# sample, but you can use any other .NET language or PowerShell.
using (var connection = new SqlConnection("Data Source=.;Integrated Security=SSPI"))
{
var serverConnection = new ServerConnection(connection);
var server = new Server(serverConnection);
var defaultDataPath = string.IsNullOrEmpty(server.Settings.DefaultFile) ? server.MasterDBPath : server.Settings.DefaultFile;
var defaultLogPath = string.IsNullOrEmpty(server.Settings.DefaultLog) ? server.MasterDBLogPath : server.Settings.DefaultLog;
}
It is so much simpler in SQL Server 2012 and above, assuming you have default paths set (which is probably always a right thing to do):
select
InstanceDefaultDataPath = serverproperty('InstanceDefaultDataPath'),
InstanceDefaultLogPath = serverproperty('InstanceDefaultLogPath')
You say that the matrices are the same dimensions, and yet you are trying to perform matrix multiplication on them. Multiplication of matrices with the same dimension is only possible if they are square. In your case, you get an assertion error, because the dimensions are not square. You have to be careful when multiplying matrices, as there are two possible meanings of multiply.
Matrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple *
operator:
C = A * B
Element-wise multiplication is where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using the mul()
function:
output = A.mul(B);
if you are just getting a single value out of either (not in a loop) then both do bounds checking (you're in managed code remember) it's just the list does it twice. See the notes later for why this is likely not a big deal.
If you are using your own for(int int i = 0; i < x.[Length/Count];i++) then the key difference is as follows:
If you are using foreach then the key difference is as follows:
The bounds checking is often no big deal (especially if you are on a cpu with a deep pipeline and branch prediction - the norm for most these days) but only your own profiling can tell you if that is an issue. If you are in parts of your code where you are avoiding heap allocations (good examples are libraries or in hashcode implementations) then ensuring the variable is typed as List not IList will avoid that pitfall. As always profile if it matters.
The answer I would provide is that a keystore file is to authenticate yourself to anyone who is asking. It isn't restricted to just signing .apk files, you can use it to store personal certificates, sign data to be transmitted and a whole variety of authentication.
In terms of what you do with it for Android and probably what you're looking for since you mention signing apk's, it is your certificate. You are branding your application with your credentials. You can brand multiple applications with the same key, in fact, it is recommended that you use one certificate to brand multiple applications that you write. It easier to keep track of what applications belong to you.
I'm not sure what you mean by implications. I suppose it means that no one but the holder of your certificate can update your application. That means that if you release it into the wild, lose the cert you used to sign the application, then you cannot release updates so keep that cert safe and backed up if need be.
But apart from signing apks to release into the wild, you can use it to authenticate your device to a server over SSL if you so desire, (also Android related) among other functions.
It means you're in "record macro" mode. This mode is entered by typing q
followed by a register name, and can be exited by typing q
again.
In strings there is a '\0'
character at the end so the length of the string can be gotten using functions like strlen
. The problem with an integer array, for example, is that you can't use any value as an end value so one possible solution is to address the array and use as an end value the NULL
pointer.

On modern browsers, you can use the input

$("#textbox").on('input',function() {alert("Change detected!");});
... And here is the rounding way which doesn't truncate. Hurried to look it up in the Java API Manual:
double d = 1234.56;
long x = Math.round(d); //1235
The legend titles can be labeled by specific aesthetic.
This can be achieved using the guides()
or labs()
functions from ggplot2
(more here and here). It allows you to add guide/legend properties using the aesthetic mapping.
Here's an example using the mtcars
data set and labs()
:
ggplot(mtcars, aes(x=mpg, y=disp, size=hp, col=as.factor(cyl), shape=as.factor(gear))) +
geom_point() +
labs(x="miles per gallon", y="displacement", size="horsepower",
col="# of cylinders", shape="# of gears")
Answering the OP's question using guides()
:
# transforming the data from wide to long
require(reshape2)
dfm <- melt(df, id="TY")
# creating a scatterplot
ggplot(data = dfm, aes(x=TY, y=value, color=variable)) +
geom_point(size=5) +
labs(title="Temperatures\n", x="TY [°C]", y="Txxx") +
scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
theme_bw() +
guides(color=guide_legend("my title")) # add guide properties by aesthetic
Use attributed string:
// Define attributes
let labelFont = UIFont(name: "HelveticaNeue-Bold", size: 18)
let attributes :Dictionary = [NSFontAttributeName : labelFont]
// Create attributed string
var attrString = NSAttributedString(string: "Foo", attributes:attributes)
label.attributedText = attrString
You need to define attributes.
Using attributed string you can mix colors, sizes, fonts etc within one text

Place an apostrophe in front of the date and it should export in the correct format. Just found it out for myself, I found this thread searching for an answer.
Does the race conditions really matter if you first try an update followed by an insert? Lets say you have two threads that want to set a value for key key:
Thread 1: value = 1
Thread 2: value = 2
Example race condition scenario
The other thread fails with insert (with error duplicate key) - thread 2.
But; in a multithreaded environment, the OS scheduler decides on the order of the thread execution - in the above scenario, where we have this race condition, it was the OS that decided on the sequence of execution. Ie: It is wrong to say that "thread 1" or "thread 2" was "first" from a system viewpoint.
When the time of execution is so close for thread 1 and thread 2, the outcome of the race condition doesn't matter. The only requirement should be that one of the threads should define the resulting value.
For the implementation: If update followed by insert results in error "duplicate key", this should be treated as success.
Also, one should of course never assume that value in the database is the same as the value you wrote last.

I found it interesting to use list comprehension or map with just one object name x. Note that whenever x is reassigned, its id(x) changes, i.e. points to a different object.

I can recommend Elasticvue, which is modern, free and open source. It allows accessing your ES instance via browser add-ons quite easily (supports Firefox, Chrome, Edge). But there are also further ways.
Just make sure you set cors values in elasticsearch.yml appropiate.
It's not clear whether you're asking this because you are new to programming, but if that's the case then you should probably read this article on loops and indeed read some basic materials on programming.
If you already know about control structures and you want the R-specific implementation details then there are dozens of tutorials around, such as this one. The other answer uses replicate
and colMeans
, which is idiomatic when writing in R and probably blazing fast as well, which is important if you want 10,000 iterations.
However, one more general and (for beginners) straightforward way to approach problems of this sort would be to use a for
loop.
> for (ii in 1:5) { + print(ii) + } [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 >
So in your case, if you just wanted to print the mean of your Tandem
object 5 times:
for (ii in 1:5) { Tandem <- sample(OUT, size = 815, replace = TRUE, prob = NULL) TandemMean <- mean(Tandem) print(TandemMean) }
As mentioned above, replicate
is a more natural way to deal with this specific problem using R. Either way, if you want to store the results - which is surely the case - you'll need to start thinking about data structures like vectors and lists. Once you store something you'll need to be able to access it to use it in future, so a little knowledge is vital.
set.seed(1234) OUT <- runif(100000, 1, 2) tandem <- list() for (ii in 1:10000) { tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) } tandem[1] tandem[100] tandem[20:25]
...creates this output:
> set.seed(1234) > OUT <- runif(100000, 1, 2) > tandem <- list() > for (ii in 1:10000) { + tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) + } > > tandem[1] [[1]] [1] 1.511923 > tandem[100] [[1]] [1] 1.496777 > tandem[20:25] [[1]] [1] 1.500669 [[2]] [1] 1.487552 [[3]] [1] 1.503409 [[4]] [1] 1.501362 [[5]] [1] 1.499728 [[6]] [1] 1.492798 >

<item name="colorAccent">your_color</item> <!-- for checked state -->
<item name="colorControlNormal">your color</item> <!-- for unchecked state -->
</style>
You can also use the RestSharp library for example
var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");
client.Authenticator = new HttpBasicAuthenticator(userName, password);
var request = new RestRequest(Method.POST);
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
value = (round(value*100)) / 100.0;
From what I know
3 one-liners
a = 10 if <condition>
example:
a = 10 if true # a = 10
b = 10 if false # b = nil
a = 10 unless <condition>
example:
a = 10 unless false # a = 10
b = 10 unless true # b = nil
a = <condition> ? <a> : <b>
example:
a = true ? 10 : 100 # a = 10
a = false ? 10 : 100 # a = 100
I hope it helps.
Calling .parents(".box .something1")
will return all parent elements that match the selector .box .something
. In other words, it will return parent elements that are .something1
and are inside of .box
.
You need to get the children of the closest parent, like this:
$(this).closest('.box').children('.something1')
This code calls .closest
to get the innermost parent matching a selector, then calls .children
on that parent element to find the uncle you're looking for.
Exactly like this
window.open("www.youraddress.com","_self")
Siddharth's answer is nice, but relies on globally-scoped variables. There's a better, more OOP-friendly way.
A UserForm is a class module like any other - the only difference is that it has a hidden VB_PredeclaredId
attribute set to True
, which makes VB create a global-scope object variable named after the class - that's how you can write UserForm1.Show
without creating a new instance of the class.
Step away from this, and treat your form as an object instead - expose Property Get
members and abstract away the form's controls - the calling code doesn't care about controls anyway:
Option Explicit
Private cancelling As Boolean
Public Property Get UserId() As String
UserId = txtUserId.Text
End Property
Public Property Get Password() As String
Password = txtPassword.Text
End Property
Public Property Get IsCancelled() As Boolean
IsCancelled = cancelling
End Property
Private Sub OkButton_Click()
Me.Hide
End Sub
Private Sub CancelButton_Click()
cancelling = True
Me.Hide
End Sub
Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
If CloseMode = VbQueryClose.vbFormControlMenu Then
cancelling = True
Cancel = True
Me.Hide
End If
End Sub
Now the calling code can do this (assuming the UserForm was named LoginPrompt
):
With New LoginPrompt
.Show vbModal
If .IsCancelled Then Exit Sub
DoSomething .UserId, .Password
End With
Where DoSomething
would be some procedure that requires the two string parameters:
Private Sub DoSomething(ByVal uid As String, ByVal pwd As String)
'work with the parameter values, regardless of where they came from
End Sub
The Timer function also applies to Access 2007, Access 2010, Access 2013, Access 2016, Access 2007 Developer, Access 2010 Developer, Access 2013 Developer. Insert this code to to pause time for certain amount of seconds
T0 = Timer
Do
Delay = Timer - T0
Loop Until Delay = 1 'Change this value to pause time in second
They are used for different purposes and in fact have different operator precedences. The &&
and ||
operators are intended for Boolean conditions, whereas and
and or
are intended for control flow.
For example, the following is a Boolean condition:
if ($foo == $bar && $baz != $quxx) {
This differs from control flow:
doSomething() or die();
You can undo whatever you did with
rails generate xxx
By
rails destroy xxx
For example this applies generators to migration, scaffold, model...etc
('my string'.match(/\s/g) || []).length;
you can use: content:url("image.jpg")
<style>
.your-class-name{
content: url("http://imgur.com/SZ8Cm.jpg");
}
</style>
<img class="your-class-name" src="..."/>
You can also try find() method. It determines if string str occurs in string, or in a substring of string.
str1 = "please help me out so that I could solve this"
str2 = "please help me out"
if (str1.find(str2)>=0):
print("True")
else:
print ("False")
Hi if you are having dropdownlist like this
<select id="testID">
<option value="1">Value1</option>
<option value="2">Value2</option>
<option value="3">Value3</option>
<option value="4">Value4</option>
<option value="5">Value5</option>
<option value="6">Value6</option>
</select>
<input type="button" value="Get dropdown selected Value" onclick="getHTML();">
after giving id to dropdownlist you just need to add jquery code like this
function getHTML()
{
var display=$('#testID option:selected').html();
alert(display);
}
You are reusing the customer

What you are doing is adding to the list the same customer
and then modifying it. Thus setting the same values for all of objects. That's why you see the last. Because all are the same.
while (rs.next()) {
Customer customer = new Customer();
customer.setId(rs.getInt("id"));

You are looking for the command scandir.

$files = array_diff(scandir($path), array('.', '..'));
WorksheetFunction Transpose()
Instead of copying, pasting via PasteSpecial, and using the Transpose
option you can simply type a formula
=TRANSPOSE(Sheet1!A1:A5)
or if you prefer VBA:
Dim v
v = WorksheetFunction.Transpose(Sheet1.Range("A1:A5"))
Sheet2.Range("A1").Resize(1, UBound(v)) = v
Note: alternatively you could use late-bound Application.Transpose
instead.
MS help reference states that having a current version of Microsoft 365, one can simply input the formula in the top-left-cell of the target range, otherwise the formula must be entered as a legacy array formula via Ctrl+Shift+Enter to confirm it.

Regex.Replace
does not modify its first argument (recall that strings are immutable in .NET) so the call
Regex.Replace(LastName, @"\s+", "");
leaves the LastName
string unchanged. You need to call it like this:
LastName = Regex.Replace(LastName, @"\s+", "");
All three of your regular expressions would have worked. However, the first regex would remove all plus characters as well, which I imagine would be unintentional.
If a table name contains underscores or upper case, you need to surround it in double-quotes.

Also look into the PEAR mail package Pear Mail Page
It seems to be a little more robust than the standard mail() function that is built in (if the standard function isn't adequate).
Here is an excerpt from this page showing how it is used. PEAR Mail send() usage
<?php
include('Mail.php');
$recipients = '[email protected]';
$headers['From'] = '[email protected]';
$headers['To'] = '[email protected]';
$headers['Subject'] = 'Test message';
$body = 'Test message';
$smtpinfo["host"] = "smtp.server.com";
$smtpinfo["port"] = "25";
$smtpinfo["auth"] = true;
$smtpinfo["username"] = "smtp_user";
$smtpinfo["password"] = "smtp_password";
// Create the mail object using the Mail::factory method
$mail_object =& Mail::factory("smtp", $smtpinfo);
$mail_object->send($recipients, $headers, $body);
?>
The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:
The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?
This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.
In other words, the feature is missing to remove the temptation to use the feature insecurely.
I had the same problem in windows The error was that I had installed several versions of PHP and the Environment Variables were routing to wrong Path of php see image example
From my experience many tools offer the desired data in some kind of a table/ordered structure and also offer parameters to gather specific parts of that data. This applies to e.g. smartctl, nvidia-smi and ffmpeg/ffprobe, too. Simply speaking - often there's no need to pipe data around or to open subshells for such a task.
As a consequence I'd use the right tool for the job - in that case ffprobe would return the raw duration value in seconds, afterwards one could create the desired time format on his own:
$ ffmpeg --version
ffmpeg version 2.2.3 ...
The command may vary dependent on the version you are using.
#!/usr/bin/env bash
input_file="/path/to/media/file"
# Get raw duration value
ffprobe -v quiet -print_format compact=print_section=0:nokey=1:escape=csv -show_entries format=duration "$input_file"
An explanation:
"-v quiet": Don't output anything else but the desired raw data value
"-print_format": Use a certain format to print out the data
"compact=": Use a compact output format
"print_section=0": Do not print the section name
":nokey=1": do not print the key of the key:value pair
":escape=csv": escape the value
"-show_entries format=duration": Get entries of a field named duration inside a section named format
Reference: ffprobe man pages
SERVER_IP="$(ip addr show ens160 | grep 'inet ' | cut -f2 | awk '{ print $2}')"
replace ens160 with your interface name
In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.

By default, Android Studio has a maximum heap size of 1280MB. If you are working on a large project, or your system has a lot of RAM, you can improve performance by increasing the maximum heap size for Android Studio processes, such as the core IDE, Gradle daemon, and Kotlin daemon.
If you use a 64-bit system that has at least 5 GB of RAM, you can also adjust the heap sizes for your project manually. To do so, follow these steps:
Click File > Settings from the menu bar (or Android Studio > Preferences on macOS). Click Appearance & Behavior > System Settings > Memory Settings.

With help from numpy one can calculate for example a linear fitting.
# plot the data itself
pylab.plot(x,y,'o')
# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

Please check Michael answer and vote for it. It is the right way to check open ports. Netstat and other tools are not any use if you are developing services or daemons. For instance, I am crating modbus TCP server and client services for an industrial network. The services can listen to any port, but the question is whether that port is open? The program is going to be used in different places, and I cannot check them all manually, so this is what I did:
from contextlib import closing
import socket
class example:
def __init__():
self.machine_ip = socket.gethostbyname(socket.gethostname())
self.ready:bool = self.check_socket()
def check_socket(self)->bool:
result:bool = True
with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as sock:
modbus_tcp_port:int = 502
if not sock.connect_ex((self.machine_ip, modbus_tcp_port)) == 0:
result = False
return result
You can use the setupFiles
feature of the Jest configuration. As the documentation said that,
A list of paths to modules that run some code to configure or set up the testing environment. Each setupFile will be run once per test file. Since every test runs in its own environment, these scripts will be executed in the testing environment immediately before executing the test code itself.
npm install dotenv
dotenv that uses to access environment variable.
Create your .env
file to the root directory of your application and add this line into it:
#.env
APP_PORT=8080
Create your custom module file as its name being someModuleForTest.js and add this line into it:
// someModuleForTest.js
require("dotenv").config()
Update your jest.config.js
file like this:
module.exports = {
setupFiles: ["./someModuleForTest"]
}
You can access an environment variable within all test blocks.
test("Some test name", () => {
expect(process.env.APP_PORT).toBe("8080")
})
Try this:
$( ".form_datetime" ).datepicker( $.datepicker.regional[ "zh-CN" ], { dateFormat: 'dd.mm.yyyy hh:ii' });
In Class1:
Class2 inst = new Class2();
inst.UpdateEmployee();
Swift 2.x
extension NSDate {
func currentDateInDayMonthYear() -> String {
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "d LLLL yyyy"
return dateFormatter.stringFromDate(self)
}
}
You can use it as
NSDate().currentDateInDayMonthYear()
Output
6 March 2016
Use ServiceController to start your service from code.
Update: And more correct way to start service from the command line is to use "sc" (Service Controller) command instead of "net".
You can easy get that effect without using jQueryUI, for example:
$(document).ready(function(){
$('#slide').click(function(){
var hidden = $('.hidden');
if (hidden.hasClass('visible')){
hidden.animate({"left":"-1000px"}, "slow").removeClass('visible');
} else {
hidden.animate({"left":"0px"}, "slow").addClass('visible');
}
});
});
Try this working Fiddle:
I know this topic is so old but here is my solution about passing parameters in setInterval
function.
Html:
var fiveMinutes = 60 * 2;
var display = document.querySelector('#timer');
startTimer(fiveMinutes, display);
JavaScript:
function startTimer(duration, display) {
var timer = duration,
minutes, seconds;
setInterval(function () {
minutes = parseInt(timer / 60, 10);
seconds = parseInt(timer % 60, 10);
minutes = minutes < 10 ? "0" + minutes : minutes;
seconds = seconds < 10 ? "0" + seconds : seconds;
display.textContent = minutes + ":" + seconds;
--timer; // put boolean value for minus values.
}, 1000);
}
Know it's an old post. But these issues still exist.
Here are some of my findings on the subject, grossly explained.
"Status" 0 means one of 3 things, as per the XMLHttpRequest spec:
dns name resolution failed (that's for instance when network plug is pulled out)
server did not answer (a.k.a. unreachable or unresponding)
request was aborted because of a CORS issue (abortion is performed by the user-agent and follows a failing OPTIONS pre-flight).
If you want to go further, dive deep into the inners of XMLHttpRequest. I suggest reading the ready-state update sequence ([0,1,2,3,4] is the normal sequence, [0,1,4] corresponds to status 0, [0,1,2,4] means no content sent which may be an error or not). You may also want to attach listeners to the xhr (onreadystatechange, onabort, onerror, ontimeout) to figure out details.
From the spec (XHR Living spec):
const unsigned short UNSENT = 0;
const unsigned short OPENED = 1;
const unsigned short HEADERS_RECEIVED = 2;
const unsigned short LOADING = 3;
const unsigned short DONE = 4;
I've been down this road and eventually opted for a hardware data scope that does non-instrusive in-line monitoring. The software solutions that I tried didn't work for me. If you had a spare PC you could probably build one, albeit rather bulky. This software data scope may work, as might this, but I haven't tried either.
As suggested you need to use ng-options and unfortunately I believe you need to reference the array element for a default (unless the array is an array of strings).
The JavaScript:
function AppCtrl($scope) {
$scope.operators = [
{value: 'eq', displayName: 'equals'},
{value: 'neq', displayName: 'not equal'}
]
$scope.filterCondition={
operator: $scope.operators[0]
}
}
The HTML:
<body ng-app ng-controller="AppCtrl">
<div>Operator is: {{filterCondition.operator.value}}</div>
<select ng-model="filterCondition.operator" ng-options="operator.displayName for operator in operators">
</select>
</body>
I've worked it out.
Let's say you have a Python datetime object, d, created with datetime.now(). Its value is:
datetime.datetime(2011, 5, 25, 13, 34, 5, 787000)
You can serialize it to JSON as an ISO 8601 datetime string:
import json
json.dumps(d.isoformat())
The example datetime object would be serialized as:
'"2011-05-25T13:34:05.787000"'
This value, once received in the Javascript layer, can construct a Date object:
var d = new Date("2011-05-25T13:34:05.787000");
As of Javascript 1.8.5, Date objects have a toJSON method, which returns a string in a standard format. To serialize the above Javascript object back to JSON, therefore, the command would be:
d.toJSON()
Which would give you:
'2011-05-25T20:34:05.787Z'
This string, once received in Python, could be deserialized back to a datetime object:
datetime.strptime('2011-05-25T20:34:05.787Z', '%Y-%m-%dT%H:%M:%S.%fZ')
This results in the following datetime object, which is the same one you started with and therefore correct:
datetime.datetime(2011, 5, 25, 20, 34, 5, 787000)
When trying to translate Excel file with .xlsx suffix, you need to add additional jar, xmlbeansxxx.jar. xxxx is version, such as xmlbeans-2.3.0.jar
First, it's always worth noting that git reset --hard
is a potentially dangerous command, since it throws away all your uncommitted changes. For safety, you should always check that the output of git status
is clean (that is, empty) before using it.
Initially you say the following:
So I know that Git tracks changes I make to my application, and it holds on to them until I commit the changes, but here's where I'm hung up:
That's incorrect. Git only records the state of the files when you stage them (with git add
) or when you create a commit. Once you've created a commit which has your project files in a particular state, they're very safe, but until then Git's not really "tracking changes" to your files. (for example, even if you do git add
to stage a new version of the file, that overwrites the previously staged version of that file in the staging area.)
In your question you then go on to ask the following:
When I want to revert to a previous commit I use: git reset --hard HEAD And git returns: HEAD is now at 820f417 micro
How do I then revert the files on my hard drive back to that previous commit?
If you do git reset --hard <SOME-COMMIT>
then Git will:
master
) back to point at <SOME-COMMIT>
.<SOME-COMMIT>
.HEAD
points to your current branch (or current commit), so all that git reset --hard HEAD
will do is to throw away any uncommitted changes you have.
So, suppose the good commit that you want to go back to is f414f31
. (You can find that via git log
or any history browser.) You then have a few different options depending on exactly what you want to do:
git reset --hard f414f31
. However, this is rewriting the history of your branch, so you should avoid it if you've shared this branch with anyone. Also, the commits you did after f414f31
will no longer be in the history of your master
branch.Create a new commit that represents exactly the same state of the project as f414f31
, but just adds that on to the history, so you don't lose any history. You can do that using the steps suggested in this answer - something like:
git reset --hard f414f31
git reset --soft HEAD@{1}
git commit -m "Reverting to the state of the project at f414f31"
These two commands will help you find and kill server process
- lsof -wni tcp:3000
- kill -9 pid
In android-N, this feature is included in it. check Number-blocking update for android N
Android N now supports number-blocking in the platform and provides a framework API to let service providers maintain a blocked-number list. The default SMS app, the default phone app, and provider apps can read from and write to the blocked-number list. The list is not accessible to other app.

For more information, see android.provider.BlockedNumberContract
Update an existing project.
To compile your app against the Android N platform, you need to use the Java 8 Developer Kit (JDK 8), and in order to use some tools with Android Studio 2.1, you need to install the Java 8 Runtime Environment (JRE 8).
Open the build.gradle file for your module and update the values as follows:

Got a solution to above problem in a different way where in although i would read entire csv file, but would tweek the display part to show only the content which is desired.
import pandas as pd
df = pd.read_csv('data.csv', skipinitialspace=True)
print df[['star_name', 'ra']]
This one could help in some of the scenario's in learning basics and filtering data on the basis of columns in dataframe.
You just need to keep track of a max value like this:
int maxValue = 0;
Then as you iterate through the numbers, keep setting the maxValue to the next value if it is greater than the maxValue:
if (value > maxValue) {
maxValue = value;
}
Repeat in the opposite direction for minValue.
Make sure the variable is on the top part of the block, and in case you compile it with -ansi-pedantic
, make sure it looks like this:
function() {
int i;
i = 0;
someCode();
}
In my case I added this "app:hintTextAppearance="@color/colorPrimaryDark"
in my TextInputLayout widget.

My BASIC interpreter chops beginning and ending quotes with
str->pop_back();
str->erase(str->begin());
Of course, I always expect well-formed BASIC style strings, so I will abort with failed assert
if not:
assert(str->front() == '"' && str->back() == '"');
Just my two cents.
Using regex:
if re.match(r'^\s*$', line):
# line is empty (has only the following: \t\n\r and whitespace)
Using regex + filter()
:
filtered = filter(lambda x: not re.match(r'^\s*$', x), original)
As seen on codepad.
You can use:
QString qs;
// do things
std::cout << qs.toStdString() << std::endl;
It internally uses QString::toUtf8() function to create std::string, so it's Unicode safe as well. Here's reference documentation for QString
.
Use below code to print the error code :
echo mysqli_errno($this->db_link);
Error code will give you better idea about the error.

This can be accomplished in two steps:
1: select the element you want to change by either tagname, id, class etc.
var element = document.getElementsByTagName('h2')[0];
element.removeAttribute('style');
If you use all of the months in your code, your IDE won't let you compile, so I think you don't need unit testing.
But if you are using them with reflection, even if you delete one month, it will compile, so it's valid to put a unit test.
This is normally done at compile time (specially for performance reason) by using the header files available from the compiler or create your own. On linux you have the header file "/usr/include/endian.h"
You can save a page using php, like this:
$_SESSION['current_page'] = $_SERVER['REQUEST_URI']
And return to the page with:
header("Location: ". $_SESSION['current_page'])
One more approach using Recursive CTE..
declare @string varchar(100)
set @string ='te165st1230004616161616'
;With cte

select @string as string,0 as n
union all
select cast(replace(string,n,'') as varchar(100)),n+1

it helped me to do a push notification; or you can follow this other tutorial

but it's in spanish but you can download the code.
You can do it simply by using display: inline;
(or white-space: nowrap;
).
I hope you find this useful.
What you have from the server is a string like below:
var data = '[{"id":"197","category":"Damskie"},{"id":"198","category":"M\u0119skie"}]';
Then you can use JSON.parse
function to change it to an object. Then you access the category like below:
var dataObj = JSON.parse(data);
console.log(dataObj[0].category); //will return Damskie
console.log(dataObj[1].category); //will return Meskie
First let me mention that you probably don't want to create a file object that eventually can be opened for reading OR writing, depending on a non-reproducible condition. You need to know which methods can be used, reading or writing, which depends on what you want to do with the fileobject.
That said, you can do it as That One Random Scrub proposed, using try: ... except:. Actually that is the proposed way, according to the python motto "It's easier to ask for forgiveness than permission".
But you can also easily test for existence:
import os
# open file for reading
fn = raw_input("Enter file to open: ")
if os.path.exists(fn):
fh = open(fn, "r")
else:
fh = open(fn, "w")
Note: use raw_input() instead of input(), because input() will try to execute the entered text. If you accidently want to test for file "import", you'd get a SyntaxError.
For URL or file, use json.load()
. For string with .json content, use json.loads()
.
#! /usr/bin/python
import json
# from pprint import pprint
json_file = 'my_cube.json'
cube = '1'
with open(json_file) as json_data:
data = json.load(json_data)
# pprint(data)
print "Dimension: ", data['cubes'][cube]['dim']
print "Measures: ", data['cubes'][cube]['meas']
$("#yourbuttonid").click(function(){ document.location = "<%= Url.Action("Youraction") %>";})

The extra span
(.stretch
) can be replaced with :after
.
This still works in all the same browsers as the above solution. :after
doesn't work in IE6/7, but they're using distribute-all-lines
anyway, so it doesn't matter.
See: http://jsfiddle.net/thirtydot/EDp8R/3/
There's a minor downside to :after
: to make the last row work perfectly in Safari, you have to be careful with the whitespace in the HTML.
Specifically, this doesn't work:
<div id="container">
..
<div class="box3"></div>
<div class="box4"></div>
</div>
And this does:
<div id="container">
..
<div class="box3"></div>
<div class="box4"></div></div>
You can use this for any arbitrary number of child div
s without adding a boxN
class to each one by changing
.box1, .box2, .box3, .box4 { ...
to
#container > div { ...
This selects any div that is the first child of the #container
div, and no others below it. To generalize the background colors, you can use the CSS3 nth-order selector, although it's only supported in IE9+ and other modern browsers:
.box1, .box3 { ...
becomes:
#container > div:nth-child(odd) { ...
See here for a jsfiddle example.
The infix operator %>%
is not part of base R, but is in fact defined by the package magrittr
(CRAN) and is heavily used by dplyr
(CRAN).
It works like a pipe, hence the reference to Magritte's famous painting The Treachery of Images.
What the function does is to pass the left hand side of the operator to the first argument of the right hand side of the operator. In the following example, the data frame iris
gets passed to head()
:
library(magrittr)
iris %>% head()
Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1 5.1 3.5 1.4 0.2 setosa
2 4.9 3.0 1.4 0.2 setosa
3 4.7 3.2 1.3 0.2 setosa
4 4.6 3.1 1.5 0.2 setosa
5 5.0 3.6 1.4 0.2 setosa
6 5.4 3.9 1.7 0.4 setosa
Thus, iris %>% head()
is equivalent to head(iris)
.
Often, %>%
is called multiple times to "chain" functions together, which accomplishes the same result as nesting. For example in the chain below, iris
is passed to head()
, then the result of that is passed to summary()
.
iris %>% head() %>% summary()
Thus iris %>% head() %>% summary()
is equivalent to summary(head(iris))
. Some people prefer chaining to nesting because the functions applied can be read from left to right rather than from inside out.
The only thing that worked for me is:
sudo install_name_tool -change libmysqlclient.18.dylib \
/usr/local/mysql-5.6.23-osx10.8-x86_64/lib/libmysqlclient.18.dylib \
/Library/Ruby/Gems/2.0.0/gems/mysql2-0.4.3/lib/mysql2/mysql2.bundle

hashMaps
can't have duplicate keys. That said, you can create a map with list values:
Map<Integer, List<String>>
However, using this approach will have performance implications.
This issue appears to be causing ongoing consternation, so I will attempt to give a clearer answer than the previously posted answers, which only contain partial hints as to what's happening.
Rosetta Flash
that demonstrated a way for hackers to run malicious Flash SWF files from a remote domain in a manner which tricks browsers into thinking it came from the same domain the user was currently browsing. This allows bypassing of the "same-origin policy" and can permit hackers a variety of exploits. You can read the details here: https://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/
Content-Disposition: attachment; filename=f.txt
on the returns from JSONP endpoints. This has the annoyance of causing the browser to automatically download a file called f.txt
that you didn't request—but it is far better than your browser automatically running a possibly malicious Flash file.ad.doubleclick.net
probably serves out hundreds of thousands of different ads and only a small percentage likely contain malicious content. This is why various users online are confused thinking they fixed the issue or somehow affected it by uninstalling this program or running that scan, when in fact it is all unrelated. The f.txt
download just means you were protected from a recent potential attack with this exploit and you should have no reason to believe you were compromised in any way.f.txt
file from being downloaded again in the future would be to block the most common domains that appear to be serving this exploit. I've put a short list below of some of the ones implicated in various posts. If you wanted to block these domains from touching your computer, you could add them to your firewall or alternatively you could use the HOSTS
file technique described in the second section of this link: http://www.chromefans.org/chrome-tutorial/how-to-block-a-website-in-google-chrome.htmad.doubleclick.net

However, if you do end up using rm instead of git rm. You can skip the git add and directly commit the changes using:
git commit -a
As a couple of the other answers have mentioned, there can be problems when installing from the SD card. In my case I was distributing my app via email attachment, and it usually worked fine. Just open the email and download the attachment (it apparently goes to the SD card) and click on it again and it gets installed.
But then one day it didn't work, and it turned out it was because I had the phone connected to my development PC via USB, and that placed the SD card in a different mode or something. So the solution was simply to disconnect the phone from the PC and then send the e-mail again and download the attachment again. Or else place the USB connection in "charging only" mode so the SD card is not "connected" to the PC.
One way to solve this problem, specialization of member functions is to put the specialization into another class, then inherit from that class. You may have to change the order of inheritence to get access to all of the other underlying data but this technique does work.
template< class T, bool condition> struct FooImpl;
template<class T> struct FooImpl<T, true> {
T foo() { return 10; }
};
template<class T> struct FoolImpl<T,false> {
T foo() { return 5; }
};
template< class T >
class Y : public FooImpl<T, boost::is_integer<T> > // whatever your test is goes here.
{
public:
typedef FooImpl<T, boost::is_integer<T> > inherited;
// you will need to use "inherited::" if you want to name any of the
// members of those inherited classes.
};
The disadvantage of this technique is that if you need to test a lot of different things for different member functions you'll have to make a class for each one, and chain it in the inheritence tree. This is true for accessing common data members.
Ex:
template<class T, bool condition> class Goo;
// repeat pattern above.
template<class T, bool condition>
class Foo<T, true> : public Goo<T, boost::test<T> > {
public:
typedef Goo<T, boost::test<T> > inherited:
// etc. etc.
};
#how to trim a multi line string or a file

process(line)
#we could also be reading a file line by line.. e.g. my_file=open(filename), or with open(filename) as myfile:
for line in my_file:
line=line.strip()
process(line)
#moot point: note splitlines() removed the newline characters, we can keep them by passing True:
#although split() will then remove them anyway..
s2=s.splitlines(True)
print s2
[' line one\n', '\tline two\t\n', 'line three ']
There is only one user Location, so you can iterate List of nearby places can call the distanceTo()
function to get the distance, you can store in an array if you like.
From what I understand, distanceBetween()
is for far away places, it's output is a WGS84 ellipsoid.
A regular expression can be used to offer more control over the whitespace characters that are combined.
To match unicode whitespace:
import re
_RE_COMBINE_WHITESPACE = re.compile(r"\s+")
my_str = _RE_COMBINE_WHITESPACE.sub(" ", my_str).strip()
To match ASCII whitespace only:
import re
_RE_COMBINE_WHITESPACE = re.compile(r"(?a:\s+)")
_RE_STRIP_WHITESPACE = re.compile(r"(?a:^\s+|\s+$)")
my_str = _RE_COMBINE_WHITESPACE.sub(" ", my_str)
my_str = _RE_STRIP_WHITESPACE.sub("", my_str)
Matching only ASCII whitespace is sometimes essential for keeping control characters such as x0b, x0c, x1c, x1d, x1e, x1f.
About \s
:
For Unicode (str) patterns: Matches Unicode whitespace characters (which includes [ \t\n\r\f\v], and also many other characters, for example the non-breaking spaces mandated by typography rules in many languages). If the ASCII flag is used, only [ \t\n\r\f\v] is matched.
About re.ASCII
:
Make \w, \W, \b, \B, \d, \D, \s and \S perform ASCII-only matching instead of full Unicode matching. This is only meaningful for Unicode patterns, and is ignored for byte patterns. Corresponds to the inline flag (?a).
strip()
will remote any leading and trailing whitespaces.

If you don't/can't keep the connection open you could use screen, if you have the rights to install it.
user@localhost $ screen -t remote-command
user@localhost $ ssh user@target # now inside of a screen session
user@remotehost $ cd /some/directory; program-to-execute &
To detach the screen session: ctrl-a d
To list screen sessions:
screen -ls
To reattach a session:
screen -d -r remote-command
Note that screen can also create multiple shells within each session. A similar effect can be achieved with tmux.
user@localhost $ tmux
user@localhost $ ssh user@target # now inside of a tmux session
user@remotehost $ cd /some/directory; program-to-execute &
To detach the tmux session: ctrl-b d
To list screen sessions:
tmux list-sessions
To reattach a session:
tmux attach <session number>
The default tmux control key, 'ctrl-b', is somewhat difficult to use but there are several example tmux configs that ship with tmux that you can try.
You can change the global tint color in your storyboard by clicking on an empty space on the board and select in the right toolbar "Show the file inspector", and you will see in the bottom of the toolbar the "Global Tint" option.
This error may be a permission one. So, test executing the command with -H flag:
sudo -H pip3 install numpy
In addition to testing using the "is" operator, you can decorate your methods to make sure that variables passed to it implement a particular interface, like so:
public static void BubbleSort<T>(ref IList<T> unsorted_list) where T : IComparable
{
//Some bubbly sorting
}
I'm not sure which version of .Net this was implemented in so it may not work in your version.
The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.
According to this Google blogpost:
It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.
When referencing the mipmap- folders ensure you are using the following reference:
android:icon="@mipmap/ic_launcher"
The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.
Using TinyMCE editor, the only way I was able to remove all borders was to use border:hidden
in the style like this:
<style>
table, tr {border:hidden;}
td, th {border:hidden;}
</style>
And in the HTML like this:
<table style="border:hidden;"</table>

Use:
columns = ['Col1', 'Col2', ...]
df.drop(columns, inplace=True, axis=1)
This will delete one or more columns in-place. Note that inplace=True
was added in pandas v0.13 and won't work on older versions. You'd have to assign the result back in that case:
df = df.drop(columns, axis=1)

Her is another R base
approach:
From your example: Some date:
Some_date<-"01/01/1979"
We tell R, "That is a Date"
Some_date<-as.Date(Some_date)
We extract the month:
months(Some_date)
output: [1] "January"
Finally, we can convert it to a numerical variable:
as.numeric(as.factor(months(Some_date)))
outpt: [1] 1
Here's the simple check, and creates the dir if doesn't exists:
## Provide the dir name(i.e sub dir) that you want to create under main dir:
output_dir <- file.path(main_dir, sub_dir)
if (!dir.exists(output_dir)){
dir.create(output_dir)
} else {
print("Dir already exists!")
}
You can use
ContextCompat.getDrawable(getApplicationContext(),R.drawable.example);
that's work for me
I also encountered the same issue and I did what @cdeerinck suggested and got to the following link which suggested adding a user-defined variable to the Build Settings to disable batch mode i.e. add a new user defined variable named SWIFT_ENABLE_BATCH_MODE and set it to NO, I was able to get more insights into the issue and I got to know that the error was in a framework using CommonCrypto which was added to it(by me) but since Xcode 10 it is exposed natively as part of Swift (for Apple platforms only), and adding it (or its existence from the previous version) was causing a name collision and hence it was throwing the error. To know more refer to the this link which explains the issue in more detail.

The solution of Rob Stevenson-Legget is slow because he doesn't bind his values but he uses string.Format( ).
When you ask Oracle to execute a sql statement it starts with calculating the has value of this statement. After that it looks in a hash table whether it already knows this statement. If it already knows it statement it can retrieve its execution path from this hash table and execute this statement really fast because Oracle has executed this statement before. This is called the library cache and it doesn't work properly if you don't bind your sql statements.
For example don't do:
int n;
for (n = 0; n < 100000; n ++)
{
mycommand.CommandText = String.Format("INSERT INTO [MyTable] ([MyId]) VALUES({0})", n + 1);
mycommand.ExecuteNonQuery();
}
but do:
OracleParameter myparam = new OracleParameter();
int n;
mycommand.CommandText = "INSERT INTO [MyTable] ([MyId]) VALUES(?)";
mycommand.Parameters.Add(myparam);
for (n = 0; n < 100000; n ++)
{
myparam.Value = n + 1;
mycommand.ExecuteNonQuery();
}
Not using parameters can also cause sql injection.
Use a simple background image for the textarea suffice.
Or
<div onselectstart="return false">your text</div>
In SQLPlus while creating a table it is be like as
SQL> create table Test
( Test_ID number not null,
Test_Date date default sysdate not null );
SQL> insert into Test(id) values (1);
Test_ID Test_Date
1 08-MAR-19
I would suggest Jquery:
$("#log").html("Type what you want to be shown to the user");
You can also do this without using JQuery, like so:
<div id="myModal">
var modal = document.getElementById('myModal');
modal.backdrop = "static";
modal.keyboard = false;
By Timestamp
, I presume you mean java.sql.Timestamp
. You will notice that this class has a constructor that accepts a long
argument. You can parse this using the DateFormat
class:
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date date = dateFormat.parse("23/09/2007");
long time = date.getTime();
new Timestamp(time);
Use the following instead:
boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );
This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.
Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.
