Try using %0A
in the URL, just like you've used %20
instead of the space character.
[^,;]+
You haven't specified the regex implementation you are using. Most of them have a Split
method that takes delimiters and split by them. You might want to use that one with a "normal" (without ^
) character class:
[,;]+
This is because of ng-include
which creates a new child scope, so $scope.lineText
isn’t changed. I think that this
refers to the current scope, so this.lineText
should be set.
I had this error because I was providing a string of arguments to subprocess.call
instead of an array of arguments. To prevent this, use shlex.split
:
import shlex, subprocess
command_line = "ls -a"
args = shlex.split(command_line)
p = subprocess.Popen(args)
Updating to use tibble()
You can pass a named vector of length greater than 1 to the by
argument of left_join()
:
library(dplyr)
d1 <- tibble(
x = letters[1:3],
y = LETTERS[1:3],
a = rnorm(3)
)
d2 <- tibble(
x2 = letters[3:1],
y2 = LETTERS[3:1],
b = rnorm(3)
)
left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))
I like Aptana Studio and Redcar for rails programming.
Option 1
Delete using rimraf
NPM package
Open command prompt and change your directory to the folder where
node_modules
folder exists.
Run
rimraf node_modules
Missing rimraf ERROR then Install
npm install rimraf -g
When the installation completes, run
rimraf node_modules
Option 2:
Detele without installing anything
Create a folder with name test
in any Drive
robocopy /MIR c:\test D:\UserData\FolderToDelete > NUL
delete the folder test
and FolderToDelete
as both are empty
Why this is an issue in windows?
One of the deep nested folder structure is node_modules, Windows can’t delete the folder as its name is too long. To solve this, Easy solution, install a node module RimRaf
Tomcat is a web server and a Servlet/JavaServer Pages container. It is often used as an application server for strictly web-based applications but does not include the entire suite of capabilities that a Java EE application server would supply.

According to MSDN, e.AddedItems
:
Gets a list that contains the items that were selected.
So you could use:
private void OnMyComboBoxChanged(object sender, SelectionChangedEventArgs e)
{
string text = (e.AddedItems[0] as ComboBoxItem).Content as string;
}
You could also use SelectedItem
if you use string
values for the Items
from the sender
:
private void OnMyComboBoxChanged(object sender, SelectionChangedEventArgs e)
{
string text = (sender as ComboBox).SelectedItem as string;
}
or
private void OnMyComboBoxChanged(object sender, SelectionChangedEventArgs e)
{
string text = ((sender as ComboBox).SelectedItem as ComboBoxItem).Content as string;
}
Since both Content
and SelectedItem
are objects, a safer approach would be to use .ToString()
instead of as string
Just found an easy way to do it in the new Android Studio:
NSArray *keys = [dictionary allKeys];
NSArray *values = [dictionary allValues];
Try the following steps:
In the first example, ptr has not been initialized, so it points to an unspecified memory location. When you assign something to this unspecified location, your program blows up.
In the second example, the address is set when you say ptr = &q, so you're OK.
You can get current Fragment from fragmentManager. And if there are non of them in fragment manager you can create Fragment_1
public class MainActivity extends FragmentActivity {
public static Fragment_1 fragment_1;
public static Fragment_2 fragment_2;
public static Fragment_3 fragment_3;
public static FragmentManager fragmentManager;
@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.main);
fragment_1 = (Fragment_1) fragmentManager.findFragmentByTag("fragment1");
fragment_2 =(Fragment_2) fragmentManager.findFragmentByTag("fragment2");
fragment_3 = (Fragment_3) fragmentManager.findFragmentByTag("fragment3");
if(fragment_1==null && fragment_2==null && fragment_3==null){
fragment_1 = new Fragment_1();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment_1, "fragment1").commit();
}
}
}
also you can use setRetainInstance
to true what it will do it ignore onDestroy()
method in fragment and your application going to back ground and os kill your application to allocate more memory you will need to save all data you need in onSaveInstanceState
bundle
public class Fragment_1 extends Fragment {
private EditText title;
private Button go_next;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true); //Will ignore onDestroy Method (Nested Fragments no need this if parent have it)
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
onRestoreInstanceStae(savedInstanceState);
return super.onCreateView(inflater, container, savedInstanceState);
}
//Here you can restore saved data in onSaveInstanceState Bundle
private void onRestoreInstanceState(Bundle savedInstanceState){
if(savedInstanceState!=null){
String SomeText = savedInstanceState.getString("title");
}
}
//Here you Save your data
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString("title", "Some Text");
}
}
Your query is probably fine. "The semaphore timeout period has expired" is a Network error, not a SQL Server timeout.
There is apparently some sort of network problem between you and the SQL Server.
edit: However, apparently the query runs for 15-20 min before giving the network error. That is a very long time, so perhaps the network error could be related to the long execution time. Optimization of the underlying View might help.
If [MyTable] in your example is a View, can you post the View Definition so that we can have a go at optimizing it?
The easiest solution to this particular problem would have been to add another function within the module that would have stored the cursor in a variable global to the module. Then all the other functions could use it as well.
module1:
cursor = None
def setCursor(cur):
global cursor
cursor = cur
def method(some, args):
global cursor
do_stuff(cursor, some, args)
main program:
import module1
cursor = get_a_cursor()
module1.setCursor(cursor)
module1.method()
In simple way you can go with explode($delimiter, $string)
;
But in a broad way, with Manual Programming :
$string = "ab,cdefg,xyx,ht623";
$resultArr = [];
$strLength = strlen($string);
$delimiter = ',';
$j = 0;
$tmp = '';
for ($i = 0; $i < $strLength; $i++) {
if($delimiter === $string[$i]) {
$j++;
$tmp = '';
continue;
}
$tmp .= $string[$i];
$resultArr[$j] = $tmp;
}
Outpou : print_r($resultArr);
Array
(
[0] => ab
[1] => cdefg
[2] => xyx
[3] => ht623
)
The logic of encoding Unicode in UTF-8 is basically:
Here's a function I wrote a while back for encoding a JavaScript UTF-16 string in UTF-8:
function toUTF8Array(str) {
var utf8 = [];
for (var i=0; i < str.length; i++) {
var charcode = str.charCodeAt(i);
if (charcode < 0x80) utf8.push(charcode);
else if (charcode < 0x800) {
utf8.push(0xc0 | (charcode >> 6),
0x80 | (charcode & 0x3f));
}
else if (charcode < 0xd800 || charcode >= 0xe000) {
utf8.push(0xe0 | (charcode >> 12),
0x80 | ((charcode>>6) & 0x3f),
0x80 | (charcode & 0x3f));
}
// surrogate pair
else {
i++;
// UTF-16 encodes 0x10000-0x10FFFF by
// subtracting 0x10000 and splitting the
// 20 bits of 0x0-0xFFFFF into two halves
charcode = 0x10000 + (((charcode & 0x3ff)<<10)
| (str.charCodeAt(i) & 0x3ff));
utf8.push(0xf0 | (charcode >>18),
0x80 | ((charcode>>12) & 0x3f),
0x80 | ((charcode>>6) & 0x3f),
0x80 | (charcode & 0x3f));
}
}
return utf8;
}
And to nicely dump it into a file (on Windows at least) - Git Bash:
$ echo "`git show 60d8bdfc:src/services/LocationMonitor.java`" >> LM_60d8bdfc.java
The "
quotes are needed so it preserves newlines.
You're referencing a DOM element when doing something like $('#lastName')
. That's an element with id
attribute "lastName". Why do that? You want to reference the value stored in a local variable, completely unrelated. Try this (assuming the assignment to formObject
is in the same scope as the variable declarations) -
var formObject = {
formObject: [
{
firstName:firstName, // no need to quote variable names
lastName:lastName
},
{
phoneNumber:phoneNumber,
address:address
}
]
};
This seems very odd though: you're creating an object "formObject" that contains a member called "formObject" that contains an array of objects.
This can be done with array_splice
however, array_splice fails when inserting an array or using a string key. I wrote a function to handle all cases:
function array_insert(&$arr, $index, $val)
{
if (is_string($index))
$index = array_search($index, array_keys($arr));
if (is_array($val))
array_splice($arr, $index, 0, [$index => $val]);
else
array_splice($arr, $index, 0, $val);
}
There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:
split(string str, string pat)
Split str around pat (pat is a regular expression)
In your case, the delimiter "|
" has a special meaning as a regular expression, so it should be referred to as "\\|
".
Tried it with CSS, but its never 100% responsive, so I built a pure javascript solution. This one uses jQuery,
google.maps.event.addDomListener(window, "resize", function() {
var center = map.getCenter();
resizeMap();
google.maps.event.trigger(map, "resize");
map.setCenter(center);
});
function resizeMap(){
var h = window.innerHeight;
var w = window.innerWidth;
$("#map_canvas").width(w/2);
$("#map_canvas").height(h-50);
}
Just adding in for JupyterLab users. Ctrl, (advanced settings) and pasting the below in User References under keyboard shortcuts does the trick for me.

],
"selector": ".jp-Notebook:focus"
},
{
"command": "notebook:show-cell-outputs",

}
]
}
The Array.find
method support for Microsoft's browsers started with Edge.
The W3Schools compatibility table states that the support started on version 12, while the Can I Use compatibility table says that the support was unknown between version 12 and 14, being officially supported starting at version 15.
Both node-schedule and node-cron we can use to implement cron-based schedullers.
NOTE : for generating cron expressions , you can use this cron_maker
It would appear that the ADB daemon on the device (adbd) is disagreeing with the ADB server process on your host computer as to which version of the protocol they are speaking. Which version of the SDK are you running and what is the OS version on the device you are debugging?
What you might need to do is actually downgrade your version of the SDK tools so that the ADB daemon and process are in agreement. I thought the server process was completely backward compatible, but this could be one of those corner cases where it doesn't. Google doesn't advertise the fact that you can get their old SDK tools packages, but they can be found by looking in the archives area at http://developer.android.com.
If you're working with new versions of Django (>10) and don't want to spend time writing the model definition. you can use the ogrinspect tool.
This will create a code definition for the model .
python manage.py ogrinspect [/path/to/thecsv] Product
The output will be the class (model) definition. In this case the model will be called Product. You need to copy this code into your models.py file.
Afterwards you need to migrate (in the shell) the new Product table with:
python manage.py makemigrations
python manage.py migrate
More information here: https://docs.djangoproject.com/en/1.11/ref/contrib/gis/tutorial/
Do note that the example has been done for ESRI Shapefiles but it works pretty good with standard CSV files as well.
For ingesting your data (in CSV format) you can use pandas.
import pandas as pd
your_dataframe = pd.read_csv(path_to_csv)
# Make a row iterator (this will go row by row)
iter_data = your_dataframe.iterrows()
Now, every row needs to be transformed into a dictionary and use this dict for instantiating your model (in this case, Product())
# python 2.x
map(lambda (i,data) : Product.objects.create(**dict(data)),iter_data
Done, check your database now.
import ConfigParser
import os
class Parser(object):
"""attributes may need additional manipulation"""
def __init__(self, section):
"""section to retun all options on, formatted as an object
transforms all comma-delimited options to lists
comma-delimited lists with colons are transformed to dicts
dicts will have values expressed as lists, no matter the length
"""
c = ConfigParser.RawConfigParser()
c.read(os.path.join(os.path.dirname(__file__), 'config.cfg'))
self.section_name = section
self.__dict__.update({k:v for k, v in c.items(section)})
#transform all ',' into lists, all ':' into dicts
for key, value in self.__dict__.items():
if value.find(':') > 0:
#dict
vals = value.split(',')
dicts = [{k:v} for k, v in [d.split(':') for d in vals]]
merged = {}
for d in dicts:
for k, v in d.items():
merged.setdefault(k, []).append(v)
self.__dict__[key] = merged
elif value.find(',') > 0:
#list
self.__dict__[key] = value.split(',')
So now my config.cfg
file, which could look like this:
[server]
credentials=username:admin,password:$3<r3t
loggingdirs=/tmp/logs,~/logs,/var/lib/www/logs
timeoutwait=15
Can be parsed into fine-grained-enough objects for my small project.
>>> import config
>>> my_server = config.Parser('server')
>>> my_server.credentials
{'username': ['admin'], 'password', ['$3<r3t']}
>>> my_server.loggingdirs:
['/tmp/logs', '~/logs', '/var/lib/www/logs']
>>> my_server.timeoutwait
'15'
This is for very quick parsing of simple configs, you lose all ability to fetch ints, bools, and other types of output without either transforming the object returned from Parser
, or re-doing the parsing job accomplished by the Parser class elsewhere.
You can simply use EditorTemplates to do that, you need to create a directory named "EditorTemplates" in your controller's view folder and place a seperate view for each of your nested entities (named as entity class name)
Main view :
@model ViewModels.MyViewModels.Theme
@Html.LabelFor(Model.Theme.name)
@Html.EditorFor(Model.Theme.Categories)
Category view (/MyController/EditorTemplates/Category.cshtml) :
@model ViewModels.MyViewModels.Category
@Html.LabelFor(Model.Name)
@Html.EditorFor(Model.Products)
Product view (/MyController/EditorTemplates/Product.cshtml) :
@model ViewModels.MyViewModels.Product
@Html.LabelFor(Model.Name)
@Html.EditorFor(Model.Orders)
and so on
this way Html.EditorFor helper will generate element's names in an ordered manner and therefore you won't have any further problem for retrieving the posted Theme entity as a whole
gi switches to insertion mode, placing the cursor at the same location it was previously.
There isn't a plain CSS method for this. You might have to go with JavaScript + Regex to pop in a span.
Ideally, there would be a pseudo-element for first-word, but you're out of luck as that doesn't appear to work. We do have :first-letter and :first-line.
You might be able to use a combination of :after or :before to get at it without using a span.
>>> d = {}
>>> D = set()
>>> type(d)
<type 'dict'>
>>> type(D)
<type 'set'>
What you've made is a dictionary and not a Set.
The update
method in dictionary is used to update the new dictionary from a previous one, like so,
>>> abc = {1: 2}
>>> d.update(abc)
>>> d
{1: 2}
Whereas in sets, it is used to add elements to the set.
>>> D.update([1, 2])
>>> D
set([1, 2])
You could use str.split
to do this.
s = "<alpha.Customer[cus_Y4o9qMEZAugtnW] active_card=<alpha.AlphaObject[card]\
...>, created=1324336085, description='Customer for My Test App',\
livemode=False>"
val = s.split('[', 1)[1].split(']')[0]
Then we have:
>>> val
'cus_Y4o9qMEZAugtnW'
from itertools import count, izip
def enumerate(L, n=0):
return izip( count(n), L)
# if 2.5 has no count
def count(n=0):
while True:
yield n
n+=1
Now h = list(enumerate(xrange(2000, 2005), 1))
works.
Here you go
col-lg-2 : if the screen is large (lg) then this component will take space of 2 elements considering entire row can fit 12 elements ( so you will see that on large screen this component takes 16% space of a row)
col-lg-6 : if the screen is large (lg) then this component will take space of 6 elements considering entire row can fit 12 elements -- when applied you will see that the component has taken half the available space in the row.
Above rule is only applied when the screen is large. when the screen is small this rule is discarded and only one component per row is shown.
Below image shows various screen size widths :
Datetimes are comparable; so you can use max(datetimes_list)
and min(datetimes_list)

Anyone gets this error when 'npm install' is trying to fetch a package from HTTPS server with a self-signed or invalid certificate.
Quick and insecure solution:
npm config set strict-ssl false
Why this solution is insecure? The above command tells npm to connect and fetch module from server even server do not have valid certificate and server identity is not verified. So if there is a proxy server between npm client and actual server, it provided man in middle attack opportunity to an intruder.
Secure solution:
If any module in your package.json is hosted on a server with self-signed CA certificate then npm is unable to identify that server with an available system CA certificates. So you need to provide CA certificate for server validation with the explicit configuration in .npmrc. In .npmrc you need to provide cafile, please refer more detail about cafile configuration here
cafile=./ca-certs.pem
In ca-certs file, you can add any number of CA certificates(public) that you required to identify servers. The certificate should be in “Base-64 encoded X.509 (.CER)(PEM)” format.
For example,
# cat ca-certs.pem
DigiCert Global Root CA
=======================
-----BEGIN CERTIFICATE-----
CAUw7C29C79Fv1C5qfPrmAE.....
-----END CERTIFICATE-----
VeriSign Class 3 Public Primary Certification Authority - G5
========================================
-----BEGIN CERTIFICATE-----
MIIE0zCCA7ugAwIBAgIQ......
-----END CERTIFICATE-----
Note: once you provide cafile configuration in .npmrc, npm try to identify all server using CA certificate(s) provided in cafile only, it won't check system CA certificate bundles then. If someone wants all well-known public CA authority certificat bundle then can get from here.
One other situation when you get this error:
If you have mentioned Git URL as a dependency in package.json and git is on invalid/self-signed certificate then also npm throws a similar error. You can fix it with following configuration for git client
git config --global http.sslVerify false
==
will still test object equality. It is easy to be fooled, however:
Integer a = 10;
Integer b = 10;
System.out.println(a == b); //prints true
Integer c = new Integer(10);
Integer d = new Integer(10);
System.out.println(c == d); //prints false
Your examples with inequalities will work since they are not defined on Objects. However, with the ==
comparison, object equality will still be checked. In this case, when you initialize the objects from a boxed primitive, the same object is used (for both a and b). This is an okay optimization since the primitive box classes are immutable.
Open a command prompt and type one of the following lines according to your Visual Studio version and Operating System Architecture :
VS 2008 on 32bit Windows :
"%ProgramFiles%\Microsoft SDKs\Windows\v6.0A\bin\sn.exe" -T <assemblyname>
VS 2008 on 64bit Windows :
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v6.0A\bin\sn.exe" -T <assemblyname>
VS 2010 on 32bit Windows :
"%ProgramFiles%\Microsoft SDKs\Windows\v7.0A\bin\sn.exe" -T <assemblyname>
VS 2010 on 64bit Windows :
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v7.0A\bin\sn.exe" -T <assemblyname>
VS 2012 on 32bit Windows :
"%ProgramFiles%\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\sn.exe" -T <assemblyname>
VS 2012 on 64bit Windows :
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\sn.exe" -T <assemblyname>
VS 2015 on 64bit Windows :
"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe" -T <assemblyname>
Note that for the versions VS2012+, sn.exe application isn't anymore in bin but in a sub-folder. Also, note that for 64bit you need to specify (x86) folder.
If you prefer to use Visual Studio command prompt, just type :
sn -T <assembly>
where <assemblyname>
is a full file path to the assembly you're interested in, surrounded by quotes if it has spaces.

If you use CSS to select a monospace font, the problem of varying character length is easily solved.
You have to move the portion of the background task that updates the UI onto the main thread. There is a simple piece of code for this:
runOnUiThread(new Runnable() {
@Override
public void run() {
// Stuff that updates the UI
}
});
Documentation for Activity.runOnUiThread
.
Just nest this inside the method that is running in the background, and then copy paste the code that implements any updates in the middle of the block. Include only the smallest amount of code possible, otherwise you start to defeat the purpose of the background thread.
its a matter of speed. using the iterator accesses the elements faster. a similar question was answered here:
What's faster, iterating an STL vector with vector::iterator or with at()?
Edit: speed of access varies with each cpu and compiler
You can also use this active-link directive https://stackoverflow.com/a/23138152/1387163
Parent li will get active class when location matches /url:

A related question has been asked before: What is “above-the-fold content” in Google Pagespeed?
Firstly you have to notice that this is all about 'mobile pages'.
So when I interpreted your question and screenshot correctly, then this is not for your site!
On the contrary - doing some of the things advised by Google in their guidelines will things make worse than better for 'normal' websites.
And not everything that comes from Google is the "holy grail" just because it comes from Google. And they themselves are not a good role model if you have a look at their HTML markup.
The best advice I could give you is:
Additionally why do you use different CSS files, rather than just one?
The additional request is worse than the small amount of data volume. And after the first request the CSS file is cached anyway.
The things one should always take care of are:
And don't puzzle your brain about how to get 100% of Google's PageSpeed Insights tool ...! ;-)
Addition 1: Here is the page on which Google shows us, what they recommend for Optimize CSS Delivery.
As said before, I don't think that this is neither realistic nor that it makes sense for a "normal" website! Because mainly when you have a responsive web design it is most certain that you use media queries and other layout styles. So if you are not gonna load your CSS first and in a blocking manner you'll get a FOUT (Flash Of Unstyled Text). I really do not believe that this is "better" than at least some more milliseconds to render the page!
Imho Google is starting a new "hype" (when I have a look at all the question about it here on Stackoverflow) ...!

The correct fix is to add the property in the type definition as explained in @Nitzan Tomer's answer. If that's not an option though:
You can assign the object to a constant of type any, then call the 'non-existing' property.
const newObj: any = oldObj;
return newObj.someProperty;
You can also cast it as any
:
return (oldObj as any).someProperty;
This fails to provide any type safety though, which is the point of TypeScript.
Another thing you may consider, if you're unable to modify the original type, is extending the type like so:
interface NewType extends OldType {
someProperty: string;
}
Now you can cast your variable as this NewType
instead of any
. Still not ideal but less permissive than any
, giving you more type safety.
return (oldObj as NewType).someProperty;
i think it's pretty easy. just use this css
.content {
width: 100%;
height:(what u wanna give);
float: left;
position: fixed;
overflow: auto;
overflow-y: auto;
overflow-x: none;
}
after this just give this class to ur div just like -
<div class="content">your stuff goes in...</div>
Use
print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))
like this:
>>> my_string = "deadbeef"
>>> print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))
0xde 0xad 0xbe 0xef
>>>
On an unrelated side note ... using string
as a variable name even as an example variable name is very bad practice.
The short version of the page linked by D Shu (and without the horrible popover ads) is that this "waiting for device" problem happens when the USB device node is not accessible to your current user. The USB id is different in fastboot mode, so you can easily have permission to it in adb but not in fastboot.
To fix it (on Ubuntu; other systems may be slightly different):
Run lsusb -v | less
and find the relevant section which will look something like this:
Bus 001 Device 027: ID 18d1:4e30 Google Inc.
Couldn't open device, some information will be missing
Device Descriptor:
...
idVendor 0x18d1 Google Inc.
Now do
sudo vi /etc/udev/rules.d/11-android.rules
it's ok if that file does not yet exist; create it with a line like this, inserting your own username and vendor id:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", MODE="0640", OWNER="mbp"
then
sudo service udev restart
then verify the device node permissions have changed:
ls -Rl /dev/bus/usb
The even shorter cheesy version is to just run fastboot
as root. But then you need to run every command that talks to the device as root, which tends to cause other complications. Simpler just to fix the permissions in the long run.

Well, you're on the right path, Benno!
There are some tips regarding VBA programming that might help you out.
Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.
As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.
Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.
Now, let's have a draft code...
Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.
Hope it helps!
Private Sub Worksheet_Change(ByVal Target As Range)
Dim oSheet As Excel.Worksheet
'We only want to do something if the changed cell is B6, right?
If Target.Address = "$B$6" Then
'Checks if it's a number...
If IsNumeric(Target.Value) Then
'Let's avoid values out of your bonds, correct?
If Target.Value > 0 And Target.Value < 51 Then
'Let's assign the worksheet we'll show / hide rows to one variable and then
' use only the reference to the variable itself instead of the sheet name.
' It's safer.
'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
' the sheet index within the workbook
Set oSheet = ActiveWorkbook.Sheets("Sheet 2")
'We'll unhide before hide, to ensure we hide the correct ones
oSheet.Range("A7:A56").EntireRow.Hidden = False
oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True
End If
End If
End If
End Sub
Is this logically possible??.. I guess the approach that you must take is this way :
Str1 ="test123.00"
Str2 ="yes50.00"
This will be impossible to tackle unless you have delimiter in between test
and 123.00
eg: Str1 = "test-123.00"
Then you can split this way
Str2 = Str1.split("-");
This will return you an array of words split with "-"
Then you can do parseFloat(Str2[1])
to get the floating value i.e 123.00
If you are running a modern Intel processor make sure HAXM (Intel® Hardware Accelerated Execution Manager) is installed:
In Android SDK Manager, ensure the option is ticked (and then installed)
Run the HAXM installer via the path below:
your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe
or
your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-android.exe
This video shows all the required steps which may help you to solve the problem.
For AMD CPUs (or older Intel CPUs without VT-x technology), you will not be able to install this and the best option is to emulate your apps using Genymotion. See: Intel's HAXM equivalent for AMD on Windows OS
Unfortunately you can't.
If you really want them in that order you'll have to create a new table with the columns in that order and copy data. Or rename columns etc. There is no easy way.
Assuming the upper is the upper bound and lower is the lower bound, then you can make a random number, r, between the two bounds with:
int r = (int) (Math.random() * (upper - lower)) + lower;
If you use macports, you do not need to play with aliases or environment variables, just use the method macports already offers, explained by this Q&A:

ASP.Net Web API has Authorization Server build-in already. You can see it inside Startup.cs when you create a new ASP.Net Web Application with Web API template.
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/Token"),
Provider = new ApplicationOAuthProvider(PublicClientId),
AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
// In production mode set AllowInsecureHttp = false
AllowInsecureHttp = true
};
All you have to do is to post URL encoded username and password inside query string.
/Token/userName=johndoe%40example.com&password=1234&grant_type=password

Well, not always. Using cookies, you are good. But the "can I safely rely on the id being present" urged me to extend the discussion with an important point (mostly for reference, as the visitor count of this page seems quite high).
PHP can be configured to maintain sessions by URL-rewriting, instead of cookies. (How it's good or bad (<-- see e.g. the topmost comment there) is a separate question, let's now stick to the current one, with just one side-note: the most prominent issue with URL-based sessions -- the blatant visibility of the naked session ID -- is not an issue with internal Ajax calls; but then, if it's turned on for Ajax, it's turned on for the rest of the site, too, so there...)
In case of URL-rewriting (cookieless) sessions, Ajax calls must take care of it themselves that their request URLs are properly crafted. (Or you can roll your own custom solution. You can even resort to maintaining sessions on the client side, in less demanding cases.) The point is the explicit care needed for session continuity, if not using cookies:
If the Ajax calls just extract URLs verbatim from the HTML (as received from PHP), that should be OK, as they are already cooked (umm, cookified).
If they need to assemble request URIs themselves, the session ID needs to be added to the URL manually. (Check here, or the page sources generated by PHP (with URL-rewriting on) to see how to do it.)
From OWASP.org:
Effectively, the web application can use both mechanisms, cookies or URL parameters, or even switch from one to the other (automatic URL rewriting) if certain conditions are met (for example, the existence of web clients without cookies support or when cookies are not accepted due to user privacy concerns).
From a Ruby-forum post:
When using php with cookies, the session ID will automatically be sent in the request headers even for Ajax XMLHttpRequests. If you use or allow URL-based php sessions, you'll have to add the session id to every Ajax request url.
If it's a single String argument, do:
joinPoint.getArgs()[0];
Modify your filter like this:
filter isNumeric {
[Helpers]::IsNumeric($_)
}
function
uses the $input
variable to contain pipeline information whereas the filter
uses the special variable $_
that contains the current pipeline object.
Edit:
For a powershell syntax way you can use just a filter (w/o add-type):
filter isNumeric() {
return $_ -is [byte] -or $_ -is [int16] -or $_ -is [int32] -or $_ -is [int64] `
-or $_ -is [sbyte] -or $_ -is [uint16] -or $_ -is [uint32] -or $_ -is [uint64] `
-or $_ -is [float] -or $_ -is [double] -or $_ -is [decimal]
}
Note: Posted this answer because OP later stated in comments that they need to select the last two elements, not just the second to last one.
The :nth-child
CSS3 selector is in fact more capable than you ever imagined!
For example, this will select the last 2 elements of #container
:
#container :nth-last-child(-n+2) {}
But this is just the beginning of a beautiful friendship.
#container :nth-last-child(-n+2) {
background-color: cyan;
}
_x000D_
<div id="container">
<div>a</div>
<div>b</div>
<div>SELECT THIS</div>
<div>SELECT THIS</div>
</div>

If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.
If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

This is what worked for me:
recyclerView.setAdapter(new RecyclerViewAdapter(newList));
recyclerView.invalidate();
After creating a new adapter that contains the updated list (in my case it was a database converted into an ArrayList) and setting that as adapter, I tried recyclerView.invalidate()
and it worked.
Relative values like: height:100% will use the parent element in HTML like a reference, to use relative values in height you will need to make your html and body tags had 100% height like that:
HTML
<body>
<div class='content'></div>
</body>
CSS
html, body
{
height: 100%;
}
.content
{
background: red;
width: 100%;
height: 100%;
}
@EboMike: I didn't know that Resources.getIdentifier()
existed.
In my projects I used the following code to do that:
public static int getResId(String resName, Class<?> c) {
try {
Field idField = c.getDeclaredField(resName);
return idField.getInt(idField);
} catch (Exception e) {
e.printStackTrace();
return -1;
}
}
It would be used like this for getting the value of R.drawable.icon
resource integer value
int resID = getResId("icon", R.drawable.class); // or other resource class
I just found a blog post saying that Resources.getIdentifier()
is slower than using reflection like I did. Check it out.
If you want your result concatenated, as you show in your question, you could try something like:
>>> reduce(lambda x, y: str(x)+str(y), map(ord,"hello world"))
'10410110810811132119111114108100'
In your app style define the property colorAccent. Here you find an example
<style name="AppTheme" parent="Theme.AppCompat.Light">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/action_bar</item>
<item name="colorPrimaryDark">@color/primary_dark</item>
<item name="colorAccent">@color/action_bar</item>
</style>
i added both Convert Zero Datetime=True

seems the answer is in the comments and as an edit but to clarify this should work for you:
export BUILDDIR='your path to build directory here'
export SRCDIR='your path to source dir here'
export BOOST_ROOT="/opt/boost/boost_1_57_0"
export BOOST_INCLUDE="/opt/boost/boost-1.57.0/include"
export BOOST_LIBDIR="/opt/boost/boost-1.57.0/lib"
export BOOST_OPTS="-DBOOST_ROOT=${BOOST_ROOT} -DBOOST_INCLUDEDIR=${BOOST_INCLUDE} -DBOOST_LIBRARYDIR=${BOOST_LIBDIR}"
(cd ${BUILDDIR} && cmake ${BOOST_OPTS} ${SRCDIR})
you need to specify the arguments as command line arguments or you can use a toolchain file for that, but cmake will not touch your environment variables.

Groupby A:
In [0]: grp = df.groupby('A')
Within each group, sum over B and broadcast the values using transform. Then sort by B:
In [1]: grp[['B']].transform(sum).sort('B')
Out[1]:
B
2 -2.829710
5 -2.829710
1 0.253651
4 0.253651
0 0.551377
3 0.551377
Index the original df by passing the index from above. This will re-order the A values by the aggregate sum of the B values:
In [2]: sort1 = df.ix[grp[['B']].transform(sum).sort('B').index]
In [3]: sort1
Out[3]:
A B C
2 baz -0.528172 False
5 baz -2.301539 True
1 bar -0.611756 True
4 bar 0.865408 False
0 foo 1.624345 False
3 foo -1.072969 True
Finally, sort the 'C' values within groups of 'A' using the sort=False
option to preserve the A sort order from step 1:
In [4]: f = lambda x: x.sort('C', ascending=False)
In [5]: sort2 = sort1.groupby('A', sort=False).apply(f)
In [6]: sort2
Out[6]:
A B C
A
baz 5 baz -2.301539 True
2 baz -0.528172 False
bar 1 bar -0.611756 True
4 bar 0.865408 False
foo 3 foo -1.072969 True
0 foo 1.624345 False
Clean up the df index by using reset_index
with drop=True
:
In [7]: sort2.reset_index(0, drop=True)
Out[7]:
A B C
5 baz -2.301539 True
2 baz -0.528172 False
1 bar -0.611756 True
4 bar 0.865408 False
3 foo -1.072969 True
0 foo 1.624345 False

insert into tbl (col) values ('ABCDEFG'), ('HIJKLMNO'), ('PQRSTUVW'), ('XYZ');
select * from tbl where col like 'ABC%'
union
select * from tbl where col like 'XYZ%'

I think you are looking for this function:
http://doc.qt.io/qt-5/qdatetime.html#toTime_t
uint QDateTime::toTime_t () const
Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).
On systems that do not support time zones, this function will behave as if local time were Qt::UTC.
See also setTime_t().
Steps to convert .py to .exe in Python 3.6
pip install cx_Freeze
.pip install idna
..py
program named myfirstprog.py
.setup.py
on the current directory of your script.setup.py
file, copy the code below and save it.python setup.py build
build
. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.See the original script in my blog.
setup.py:
from cx_Freeze import setup, Executable
base = None
executables = [Executable("myfirstprog.py", base=base)]
packages = ["idna"]
options = {
'build_exe': {
'packages':packages,
},
}
setup(
name = "<any name>",
options = options,
version = "<any number>",
description = '<any description>',
executables = executables
)
EDIT:
myfirstprog.py
you should put your .py
extension file name as created in step 4;import
ed package in your .py
into packages
list (ex: packages = ["idna", "os","sys"]
)any name, any number, any description
in setup.py
file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = ''
)import
ed packages must be installed before you start step 8.As pointed out in some comments, you need to edit the policies of ImageMagick in /etc/ImageMagick-7/policy.xml
. More particularly, in ArchLinux at the time of writing (05/01/2019) the following line is uncommented:
<policy domain="coder" rights="none" pattern="{PS,PS2,PS3,EPS,PDF,XPS}" />
Just wrap it between <!--
and -->
to comment it, and pdf conversion should work again.
Below is a quick example of how to do this (which best explained the matter to me) that I essentially found at this website. That website link also explains WSDL, which is important for working with SOAP services.
However, I don't think the API address they were using in the example below still works, so just switch in one of your own choosing.
$wsdl = 'http://terraservice.net/TerraService.asmx?WSDL';
$trace = true;
$exceptions = false;
$xml_array['placeName'] = 'Pomona';
$xml_array['MaxItems'] = 3;
$xml_array['imagePresence'] = true;
$client = new SoapClient($wsdl, array('trace' => $trace, 'exceptions' => $exceptions));
$response = $client->GetPlaceList($xml_array);
var_dump($response);
You don't need the date
validator. It doesn't support dd/mm/yyyy format, and that's why you are getting "Please enter a valid date" message for input like 13/01/2014. You already have the dateITA
validator, which uses dd/mm/yyyy format as you need.
Just like the date
validator, your code for dateGreaterThan
and dateLessThan
calls new Date
for input string and has the same issue parsing dates. You can use a function like this to parse the date:
function parseDMY(value) {
var date = value.split("/");
var d = parseInt(date[0], 10),
m = parseInt(date[1], 10),
y = parseInt(date[2], 10);
return new Date(y, m - 1, d);
}
Another easy way:
SELECT Date, User, Status, Notes
FROM Test_Most_Recent
WHERE Date in ( SELECT MAX(Date) from Test_Most_Recent group by User)
Code below copied from -> Here
First off, you must save your work book as a macro enabled work book. So it would need to be xlsm
not an xlsx
. Otherwise, excel will disable the macro's due to not being macro enabled.
Set your vbscript (C:\excel\tester.vbs). The example sub "test()" must be located in your modules on the excel document.
dim eApp
set eApp = GetObject("C:\excel\tester.xlsm")
eApp.Application.Run "tester.xlsm!test"
set eApp = nothing
Then set your Schedule, give it a name, and a username/password for offline access.
Then you have to set your actions and triggers.
Set your schedule(trigger)
Action, set your vbscript to open with Cscript.exe so that it will be executed in the background and not get hung up by any error handling that vbcript has enabled.
I believe that I have the simplest answer yet using Spring Boot 1.4, included imports for the test class.:

String json = mapper.writeValueAsString(someClass);
mvc.perform(post("/someControllerUrl")

Spring has implemented an excellent classpath search function in the PathMatchingResourcePatternResolver
. If you use the classpath*
: prefix, you can find all the resources, including classes in a given hierarchy, and even filter them if you want. Then you can use the children of AbstractTypeHierarchyTraversingFilter
, AnnotationTypeFilter
and AssignableTypeFilter
to filter those resources either on class level annotations or on interfaces they implement.
Whenever you try to show a Link
on a page thats outside the BrowserRouter
you will get that error.
This error message is essentially saying that any component that is not a child of our <Router>
cannot contain any React Router related components.
You need to migrate your component hierarchy to how you see it in the first answer above. For anyone else reviewing this post who may need to look at more examples.
Let's say you have a Header.js
component that looks like this:
import React from 'react';
import { Link } from 'react-router-dom';
const Header = () => {
return (
<div className="ui secondary pointing menu">
<Link to="/" className="item">
Streamy
</Link>
<div className="right menu">
<Link to="/" className="item">
All Streams
</Link>
</div>
</div>
);
};
export default Header;
And your App.js
file looks like this:
import React from 'react';
import { BrowserRouter, Route, Link } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';
const App = () => {
return (
<div className="ui container">
<Header />
<BrowserRouter>
<div>
<Route path="/" exact component={StreamList} />
<Route path="/streams/new" exact component={StreamCreate} />
<Route path="/streams/edit" exact component={StreamEdit} />
<Route path="/streams/delete" exact component={StreamDelete} />
<Route path="/streams/show" exact component={StreamShow} />
</div>
</BrowserRouter>
</div>
);
};
export default App;
Notice that the Header.js
component is making use of the Link
tag from react-router-dom
but the componet was placed outside the <BrowserRouter>
, this will lead to the same error as the one experience by the OP. In this case, you can make the correction in one move:
import React from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';
const App = () => {
return (
<div className="ui container">
<BrowserRouter>
<div>
<Header />
<Route path="/" exact component={StreamList} />
<Route path="/streams/new" exact component={StreamCreate} />
<Route path="/streams/edit" exact component={StreamEdit} />
<Route path="/streams/delete" exact component={StreamDelete} />
<Route path="/streams/show" exact component={StreamShow} />
</div>
</BrowserRouter>
</div>
);
};
export default App;
Please review carefully and ensure you have the <Header />
or whatever your component may be inside of not only the <BrowserRouter>
but also inside of the <div>
, otherwise you will also get the error that a Router may only have one child which is referring to the <div>
which is the child of <BrowserRouter>
. Everything else such as Route
and components must go within it in the hierarchy.
So now the <Header />
is a child of the <BrowserRouter>
within the <div>
tags and it can successfully make use of the Link
element.
You have to enable auto return in your PayPal account, otherwise it will ignore the return
field.
From the documentation (updated to reflect new layout Jan 2019):
Auto Return is turned off by default. To turn on Auto Return:
- Log in to your PayPal account at https://www.paypal.com or https://www.sandbox.paypal.com The My Account Overview page appears.
- Click the gear icon top right. The Profile Summary page appears.
- Click the My Selling Preferences link in the left column.
- Under the Selling Online section, click the Update link in the row for Website Preferences. The Website Payment Preferences page appears
- Under Auto Return for Website Payments, click the On radio button to enable Auto Return.
- In the Return URL field, enter the URL to which you want your payers redirected after they complete their payments. NOTE: PayPal checks the Return URL that you enter. If the URL is not properly formatted or cannot be validated, PayPal will not activate Auto Return.
- Scroll to the bottom of the page, and click the Save button.
IPN is for instant payment notification. It will give you more reliable/useful information than what you'll get from auto-return.
Documentation for IPN is here: https://www.x.com/sites/default/files/ipnguide.pdf
Online Documentation for IPN: https://developer.paypal.com/docs/classic/ipn/gs_IPN/
The general procedure is that you pass a notify_url
parameter with the request, and set up a page which handles and validates IPN notifications, and PayPal will send requests to that page to notify you when payments/refunds/etc. go through. That IPN handler page would then be the correct place to update the database to mark orders as having been paid.
If you are using generics, all answer will give us compile error. You can use return default(T);
. Sample below to explain further.
public async Task<T> GetItemAsync<T>(string id)
{
try
{
var response = await this._container.ReadItemAsync<T>(id, new PartitionKey(id));
return response.Resource;
}
catch (CosmosException ex) when (ex.StatusCode == System.Net.HttpStatusCode.NotFound)
{
return default(T);
}
}
You could create Util class:
public final class CollectionHelpers {
public static <T> boolean addNullSafe(List<T> list, T element) {
if (list == null || element == null) {
return false;
}
return list.add(element);
}
}
And then use it:
Element element = getElementFromSomeWhere(someParameter);

The previously accepted answer has been deprecated as of Python 3.0
. Instead of using inspect.getargspec
you should now opt for the Signature
class which superseded it.
Creating a Signature for the function is easy via the signature
function:
from inspect import signature
def someMethod(self, arg1, kwarg1=None):
pass
sig = signature(someMethod)
Now, you can either view its parameters quickly by str
ing it:
str(sig) # returns: '(self, arg1, kwarg1=None)'
or you can also get a mapping of attribute names to parameter objects via sig.parameters
.
params = sig.parameters
print(params['kwarg1']) # prints: kwarg1=20
Additionally, you can call len
on sig.parameters
to also see the number of arguments this function requires:
print(len(params)) # 3
Each entry in the params
mapping is actually a Parameter
object that has further attributes making your life easier. For example, grabbing a parameter and viewing its default value is now easily performed with:
kwarg1 = params['kwarg1']
kwarg1.default # returns: None
similarly for the rest of the objects contained in parameters
.
As for Python 2.x
users, while inspect.getargspec
isn't deprecated, the language will soon be :-). The Signature
class isn't available in the 2.x
series and won't be. So you still need to work with inspect.getargspec
.
As for transitioning between Python 2 and 3, if you have code that relies on the interface of getargspec
in Python 2 and switching to signature
in 3
is too difficult, you do have the valuable option of using inspect.getfullargspec
. It offers a similar interface to getargspec
(a single callable argument) in order to grab the arguments of a function while also handling some additional cases that getargspec
doesn't:
from inspect import getfullargspec
def someMethod(self, arg1, kwarg1=None):
pass
args = getfullargspec(someMethod)
As with getargspec
, getfullargspec
returns a NamedTuple
which contains the arguments.
print(args)
FullArgSpec(args=['self', 'arg1', 'kwarg1'], varargs=None, varkw=None, defaults=(None,), kwonlyargs=[], kwonlydefaults=None, annotations={})
I actually had a very similar challenge on my current project. That broght me to the idea of writing a small script which I called docker-compose-profile (or short: dcp). I published this today on GitLab as docker-compose-profile.
So in short: I now can start several predefined docker-compose profiles using a command like dcp -p some-services "up -d"
. Feel free to try it out and give some feedback or suggestions for further improvements.
Feel free to use the function below:
function AjaxPostWithAntiForgeryToken(destinationUrl, successCallback) {
var token = $('input[name="__RequestVerificationToken"]').val();
var headers = {};
headers["__RequestVerificationToken"] = token;
$.ajax({
type: "POST",
url: destinationUrl,
data: { __RequestVerificationToken: token }, // Your other data will go here
dataType: "json",
success: function (response) {
successCallback(response);
},
error: function (xhr, status, error) {
// handle failure
}
});
}
Disabling user-scalable (namely, the ability to double tap to zoom) allows the browser to reduce the click delay. In touch-enable browsers, when the user expects the double tap to zoom, the browser generally waits 300ms before firing the click event, waiting to see if the user will double tap. Disabling user-scalable allows for the Chrome browser to fire the click event immediately, allowing for a better user experience.

A constant reference to an object is not a constant, it's just a constant reference to an object.
private static final
is not what defines something to be a constant or not. It's just the Java way to define a constant, but it doesn't mean that every private static final
declaration was put there to define a constant.
When I write private static final Logger
I'm not trying to define a constant, I'm just trying to define a reference to an object that is private
(that it is not accessible from other classes), static
(that it is a class level variable, no instance needed) and final
(that can only be assigned once). If it happens to coincide with the way Java expects you to declare a constant, well, bad luck, but it doesn't make it a constant. I don't care what the compiler, sonar, or any Java guru says. A constant value, like MILLISECONDS_IN_A_SECOND = 1000
is one thing, and a constant reference to an object is another.
Gold is known to shine, but not everything that shines is gold.
I think it is implemented in the engine as Matthias said: WHERE, GROUP BY, HAVING
Was trying to find a reference online that lists the entire sequence (i.e. "SELECT" comes right down at the bottom), but I can't find it. It was detailed in a "Inside Microsoft SQL Server 2005" book I read not that long ago, by Solid Quality Learning
Edit: Found a link: http://blogs.x2line.com/al/archive/2007/06/30/3187.aspx
I used Pauls (see his answer) Implementation of HorizontalListview and it works, thank you so much for sharing!
I slightly changed his HorizontalListView-Class (btw. Paul there is a typo in your classname, your classname is "HorizontialListView" instead of "HorizontalListView", the "i" is too much) to update child-views when selected.
UPDATE: My code that I posted here was wrong I suppose, as I ran into trouble with selection (i think it has to do with view recycling), I have to go back to the drawing board...
UPDATE 2: Ok Problem solved, I simply commented "removeNonVisibleItems(dx);" in "onLayout(..)", I guess this will hurt performance, but since I am using only very small Lists this is no Problem for me.
I basically used this tutorial here on developerlife and just replaced ListView with Pauls HorizontalListView, and made the changes to allow for "permanent" selection (a child that is clicked on changes its appearance, and when its clicked on again it changes it back).
I am a beginner, so probably many ugly things in the code, let me know if you need more details.
Using list comprehensions in python, you can collect an entire column of values into a list using just two lines:
df = sqlContext.sql("show tables in default")
tableList = [x["tableName"] for x in df.rdd.collect()]
In the above example, we return a list of tables in database 'default', but the same can be adapted by replacing the query used in sql().
Or more abbreviated:
tableList = [x["tableName"] for x in sqlContext.sql("show tables in default").rdd.collect()]
And for your example of three columns, we can create a list of dictionaries, and then iterate through them in a for loop.
sql_text = "select name, age, city from user"
tupleList = [{name:x["name"], age:x["age"], city:x["city"]}
for x in sqlContext.sql(sql_text).rdd.collect()]
for row in tupleList:
print("{} is a {} year old from {}".format(
row["name"],
row["age"],
row["city"]))
I think this answer needs an update and the solution would go better this way.
from datetime import datetime
datetime.strptime("29.08.2011 11:05:02", "%d.%m.%Y %H:%M:%S").strftime("%s")
or you may use datetime object and format the time using %s to convert it into epoch time.
Open the file for 'append' rather than 'write'.
with open('file.txt', 'a') as file:
file.write('input')
Try this
padding:8px;
overflow: hidden;
zoom: 1;
text-align: left;
font-size: 13px;
font-family: "Trebuchet MS",Arial,Sans;
line-height: 24px;
color: black;
border-bottom: solid 1px #BBB;
background:url('images/checked.gif') white no-repeat;
This is full css.. Why you use padding:0 8px
, then override it with paddings? This is what you need...
Actually you are right: it runs another instance of make. A possible solution would be:
.PHONY : clearscr fresh clean all
all :
compile executable
clean :
rm -f *.o $(EXEC)
fresh : clean clearscr all
clearscr:
clear
By calling make fresh
you get first the clean
target, then the clearscreen
which runs clear
and finally all
which does the job.
EDIT Aug 4
What happens in the case of parallel builds with make’s -j
option?
There's a way of fixing the order. From the make manual, section 4.2:
Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites
The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).
Hence the makefile becomes
.PHONY : clearscr fresh clean all
all :
compile executable
clean :
rm -f *.o $(EXEC)
fresh : | clean clearscr all
clearscr:
clear
EDIT Dec 5
It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.
log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)
install:
@[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
command1 # this line will be a subshell
command2 # this line will be another subshell
@command3 # Use `@` to hide the command line
$(call log_error, "It works, yey!")
uninstall:
@[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
....
$(call log_error, "Nuked!")
Probably one of the indexes is wrong, either the inner one or the outer one.
I suspect you mean to say [0]
where you say [1]
and [1]
where you say [2]
. Indexes are 0-based in Python.
If you mean the type of procedure you find in SQL Server, prior to 2010, you can't. If you want a query that accepts a parameter, you can use the query design window:
PARAMETERS SomeParam Text(10);
SELECT Field FROM Table
WHERE OtherField=SomeParam
You can also say:
CREATE PROCEDURE ProcedureName
(Parameter1 datatype, Parameter2 datatype) AS
SQLStatement
From: http://msdn.microsoft.com/en-us/library/aa139977(office.10).aspx#acadvsql_procs
Note that the procedure contains only one statement.
For another as Latin languages for example Cyrillic you can use something like this:
FileReader fr = new FileReader("src/text.txt", StandardCharsets.UTF_8);
and be sure that your .txt
file is saved with UTF-8
(but not as default ANSI
) format. Cheers!
Try do something like this (the problem was that you trying to use MyBook.Worksheets
, but MyBook
is not a Workbook
object, but string
, containing workbook name. I've added new varible Set WB = ActiveWorkbook
, so you can use WB.Worksheets
instead MyBook.Worksheets
):
Sub NewWBandPasteSpecialALLSheets()
MyBook = ActiveWorkbook.Name ' Get name of this book
Workbooks.Add ' Open a new workbook
NewBook = ActiveWorkbook.Name ' Save name of new book
Workbooks(MyBook).Activate ' Back to original book
Set WB = ActiveWorkbook
Dim SH As Worksheet
For Each SH In WB.Worksheets
SH.Range("WholePrintArea").Copy
Workbooks(NewBook).Activate
With SH.Range("A1")
.PasteSpecial (xlPasteColumnWidths)
.PasteSpecial (xlFormats)
.PasteSpecial (xlValues)
End With
Next
End Sub
But your code doesn't do what you want: it doesen't copy something to a new WB. So, the code below do it for you:
Sub NewWBandPasteSpecialALLSheets()
Dim wb As Workbook
Dim wbNew As Workbook
Dim sh As Worksheet
Dim shNew As Worksheet
Set wb = ThisWorkbook
Workbooks.Add ' Open a new workbook
Set wbNew = ActiveWorkbook
On Error Resume Next
For Each sh In wb.Worksheets
sh.Range("WholePrintArea").Copy
'add new sheet into new workbook with the same name
With wbNew.Worksheets
Set shNew = Nothing
Set shNew = .Item(sh.Name)
If shNew Is Nothing Then
.Add After:=.Item(.Count)
.Item(.Count).Name = sh.Name
Set shNew = .Item(.Count)
End If
End With
With shNew.Range("A1")
.PasteSpecial (xlPasteColumnWidths)
.PasteSpecial (xlFormats)
.PasteSpecial (xlValues)
End With
Next
End Sub
Because, on whatever line the error is occurring at (you didn't tell us which that is), you're passing something to foreach
that is not an array.
Look at what you're passing into foreach
, determine what it is (with var_export
), find out why it's not an array... and fix it.
Basic, basic debugging.
"location" : null // this is not really an array it's a null object
"location" : [] // this is an empty array
It looks like this API returns null when there is no location defined - instead of returning an empty array, not too unusual really - but they should tell you if they're going to do this.
The below code illustrates how using a generator returns a result before completion, unlike the traditional non generator approach that returns a complete array after full iteration. With the generator below, the values are returned when ready, no need to wait for an array to be completely filled:
<?php
function sleepiterate($length) {
for ($i=0; $i < $length; $i++) {
sleep(2);
yield $i;
}
}
foreach (sleepiterate(5) as $i) {
echo $i, PHP_EOL;
}
Here is an option using a for
loop by groups rather by rows (like OP did)
for (i in unique(df$cat)) df$num[df$cat == i] <- seq_len(sum(df$cat == i))
According to SolrQuerySyntax, you can use q=-id:[* TO *]
.
NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];
or use
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);
Having tried all of the solutions here, I realized none of them were good in all situations:
This command gets all names:
git branch -a --contains HEAD --list --format='%(refname:short)'
For my application, I had to filter out the HEAD & master refs, prefer remote refs, and strip off the word 'origin/'. and then if that wasn't found, use the first non HEAD ref that didn't have a /
or a (
in it.
While working with spark in EMR I was having the same problem and setting maximizeResourceAllocation=true
did the trick; hope it helps someone. You have to set it when you create the cluster. From the EMR docs:
aws emr create-cluster --release-label emr-5.4.0 --applications Name=Spark \
--instance-type m3.xlarge --instance-count 2 --service-role EMR_DefaultRole --ec2-attributes InstanceProfile=EMR_EC2_DefaultRole --configurations https://s3.amazonaws.com/mybucket/myfolder/myConfig.json
Where myConfig.json should say:
[
{
"Classification": "spark",
"Properties": {
"maximizeResourceAllocation": "true"
}
}
]
Pidfile contains pid of a process. It is a convention allowing long running processes to be more self-aware. Server process can inspect it to stop itself, or have heuristic that its other instance is already running. Pidfiles can also be used to conventiently kill risk manually, e.g. pkill -F <some.pid>
unicode
is meant to handle text. Text is a sequence of code points which may be bigger than a single byte. Text can be encoded in a specific encoding to represent the text as raw bytes(e.g. utf-8
, latin-1
...).
Note that unicode
is not encoded! The internal representation used by python is an implementation detail, and you shouldn't care about it as long as it is able to represent the code points you want.
On the contrary str
in Python 2 is a plain sequence of bytes. It does not represent text!
You can think of unicode
as a general representation of some text, which can be encoded in many different ways into a sequence of binary data represented via str
.
Note: In Python 3, unicode
was renamed to str
and there is a new bytes
type for a plain sequence of bytes.
Some differences that you can see:
>>> len(u'à') # a single code point
1
>>> len('à') # by default utf-8 -> takes two bytes
2
>>> len(u'à'.encode('utf-8'))
2
>>> len(u'à'.encode('latin1')) # in latin1 it takes one byte
1
>>> print u'à'.encode('utf-8') # terminal encoding is utf-8
à
>>> print u'à'.encode('latin1') # it cannot understand the latin1 byte
?
Note that using str
you have a lower-level control on the single bytes of a specific encoding representation, while using unicode
you can only control at the code-point level. For example you can do:
>>> 'àèìòù'
'\xc3\xa0\xc3\xa8\xc3\xac\xc3\xb2\xc3\xb9'
>>> print 'àèìòù'.replace('\xa8', '')
à?ìòù
What before was valid UTF-8, isn't anymore. Using a unicode string you cannot operate in such a way that the resulting string isn't valid unicode text. You can remove a code point, replace a code point with a different code point etc. but you cannot mess with the internal representation.
You need to add style="overflow-y:scroll;"
to the div tag. (This will force a scrollbar on the vertical).
If you only want a scrollbar when needed, just do overflow-y:auto;
Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

For anyone checking this question recently, Rails 5.2+ now has ActiveStorage by default & I highly recommend checking it out.
Since it is part of the core Rails 5.2+ now, it is very well integrated & has excellent capabilities out of the box (still all other well-known gems like Carrierwave, Shrine, paperclip,... are great but this one offers very good features that we can consider for any new Rails project)
Paperclip team deprecated the gem in favor of the Rails ActiveStorage.
Here is the github page for the ActiveStorage & plenty of resources are available everywhere
Also I found this video to be very helpful to understand the features of Activestorage
For the vast majority[1] of visitors here, the correct and simplest answer to the question "How do I list all remote branches in Git 1.7+?" is:
git branch -r
For a small minority[1] git branch -r
does not work. If git branch -r
does not work try:
git ls-remote --heads <remote-name>
If git branch -r
does not work, then maybe as Cascabel says "you've modified the default refspec, so that git fetch
and git remote update
don't fetch all the remote
's branches".
[1] As of the writing of this footnote 2018-Feb, I looked at the comments and see that the git branch -r
works for the vast majority (about 90% or 125 out of 140).
If git branch -r
does not work, check git config --get remote.origin.fetch
contains a wildcard (*

You create the relationships the other way around; add foreign keys to the Person
type to create a Many-to-One relationship:
class Person(models.Model):
name = models.CharField(max_length=50)
birthday = models.DateField()
anniversary = models.ForeignKey(
Anniversary, on_delete=models.CASCADE)
address = models.ForeignKey(
Address, on_delete=models.CASCADE)
class Address(models.Model):
line1 = models.CharField(max_length=150)
line2 = models.CharField(max_length=150)
postalcode = models.CharField(max_length=10)
city = models.CharField(max_length=150)
country = models.CharField(max_length=150)
class Anniversary(models.Model):
date = models.DateField()
Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person
entries.
Anniversary
and Address
objects will be given a reverse, backwards relationship too; by default it'll be called person_set
but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.

As an exploration of this topic, I have a presentation titled "Securing TodoMVC Using the Web Cryptography API" (video, code).
It uses the Web Cryptography API to store the todo list encrypted in localStorage by password protecting the application and using a password derived key for encryption. If you forget or lose the password, there is no recovery. (Disclaimer - it was a POC and not intended for production use.)
As the other answers state, this is still susceptible to XSS or malware installed on the client computer. However, any sensitive data would also be in memory when the data is stored on the server and the application is in use. I suggest that offline support may be the compelling use case.
In the end, encrypting localStorage probably only protects the data from attackers that have read only access to the system or its backups. It adds a small amount of defense in depth for OWASP Top 10 item A6-Sensitive Data Exposure, and allows you to answer "Is any of this data stored in clear text long term?" correctly.
$arrayDecoded = json_decode($arrayEncoded, true);
gives you an array.
I have solved a similar problem using external native lib dependencies that are packaged inside of jar files. Sometimes these architecture dependend libraries are packaged alltogether inside one jar, sometimes they are split up into several jar files. so i wrote some buildscript to scan the jar dependencies for native libs and sort them into the correct android lib folders. Additionally this also provides a way to download dependencies that not found in maven repos which is currently usefull to get JNA working on android because not all native jars are published in public maven repos.

filterContext.Result = new RedirectResult("~/Error");
}
}
This works well and I show the TempData on error page. Thanks to "tvanfosson" for the code snippet. I am using windows authentication and _isAuthorized is nothing but HttpContext.User.Identity.IsAuthenticated...
If you want to download SVN repository online (e.g. Google Code) without installing anything, you can use wget:
wget -m -np http://myproject.googlecode.com/svn/myproject/trunk/
If authorization is required, you can use the --user
and --ask-password
flags, which will prompt you for your password:
wget --user=yourusername --ask-password -m -np http://myproject.googlecode.com/svn/myproject/trunk/
Explaining what the parameter does:
-m, --mirror:
Turn on options suitable for mirroring. This option turns on recursion and time-stamping, sets infinite recursion depth and keeps FTP directory listings. It is currently equivalent to
-r -N -l inf --no-remove-listing
.
-np, --no-parent:
Do not ever ascend to the parent directory when retrieving recursively. This is a useful option, since it guarantees that only the files below a certain hierarchy will be downloaded.
The answers mentioning adding @Transactional
are correct, but for simplicity you could just have your test class extends AbstractTransactionalJUnit4SpringContextTests
.
Most times SDL is in /usr/include/SDL
. If so then your #include <SDL.h>
directive is wrong, it should be #include <SDL/SDL.h>
.
An alternative for that is adding the /usr/include/SDL
directory to your include directories. To do that you should add -I/usr/include/SDL
to the compiler flags...
If you are using an IDE this should be quite easy too...

It is not a problem with Eclipse. If you are using the Properties class to read and store the properties file, the class will escape all special characters.
When saving properties to a stream or loading them from a stream, the ISO 8859-1 character encoding is used. For characters that cannot be directly represented in this encoding, Unicode escapes are used; however, only a single 'u' character is allowed in an escape sequence. The native2ascii tool can be used to convert property files to and from other character encodings.
Characters less than \u0020 and characters greater than \u007E are written as \uxxxx for the appropriate hexadecimal value xxxx.
The solution which worked for me was to upgrade my setuptools:
python3 -m pip install --upgrade pip setuptools wheel
I also got this issue and this was due to wrong path that we mention while running. Check your file path and also make sure that there is no space between the name of your directory name.

a more modern approach would be to use css flex-box.
div {_x000D_
height: 50px;_x000D_
background: grey;_x000D_
display: flex;_x000D_
align-items: center_x000D_
}
_x000D_
<div>_x000D_
<label for='name'>Name:</label>_x000D_
<input type='text' id='name' />_x000D_
</div>
_x000D_
a more complex example... if you have multible elements in the flex flow, you can use align-self to align single elements differently to the specified align...
div {_x000D_
display: flex;_x000D_
align-items: center_x000D_
}_x000D_
_x000D_
* {_x000D_
margin: 10px_x000D_
}_x000D_
_x000D_
label {_x000D_
align-self: flex-start_x000D_
}
_x000D_
<div>_x000D_
<img src="https://de.gravatar.com/userimage/95932142/195b7f5651ad2d4662c3c0e0dccd003b.png?size=50" />_x000D_
<label>Text</label>_x000D_
<input placeholder="Text" type="text" />_x000D_
</div>
_x000D_
its also super easy to center horizontally and vertically:
div {_x000D_
position:absolute;_x000D_
top:0;left:0;right:0;bottom:0;_x000D_
background: grey;_x000D_
display: flex;_x000D_
align-items: center;_x000D_
justify-content:center_x000D_
}
_x000D_
<div>_x000D_
<label for='name'>Name:</label>_x000D_
<input type='text' id='name' />_x000D_

There is a php library (pdfparser) that does exactly what you want.
project website
github
https://github.com/smalot/pdfparser
Demo page/api
After including pdfparser in your project you can get all text from mypdf.pdf
like so:
<?php
$parser = new \installpath\PdfParser\Parser();
$pdf = $parser->parseFile('mypdf.pdf');
$text = $pdf->getText();
echo $text;//all text from mypdf.pdf
?>
Simular you can get the metadata from the pdf as wel as getting the pdf objects (for example images).
The problem is that the server process is 64 bit and the library is 32-bit and it tries to create the COM component in the same process (in-proc server). Either you recompile the server and make it 32-bit or you leave the server unchanged and make the COM component out-of-process. The easiest way to make a COM server out-of-process is to create a COM+ application - Control Panel -> Administrative Tools -> ComponentServices.
I'm loving all the solutions posted here, but I solved this using Conditional Formatting as a percentage-based Data Bar.
This is applied to a row of cells as shown below. The cells that include 0% and 100% are normally hidden, because they're just there to give the "ScanProgress" named range (Left) context.
In the code I'm looping through a table doing some stuff.
For intRow = 1 To shData.Range("tblData").Rows.Count
shData.Range("ScanProgress").Value = intRow / shData.Range("tblData").Rows.Count

Minimal code, looks decent.
First of all, do a backup of your needed databases with mysqldump
Note: If you want to restore later, just backup your relevant databases, and not the WHOLE, because the whole database might actually be the reason you need to purge and reinstall).
In total, do this:
sudo service mysql stop #or mysqld
sudo killall -9 mysql
sudo killall -9 mysqld
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
sudo deluser -f mysql
sudo rm -rf /var/lib/mysql
sudo apt-get purge mysql-server-core-5.7
sudo apt-get purge mysql-client-core-5.7
sudo rm -rf /var/log/mysql
sudo rm -rf /etc/mysql
All above commands in single line (just copy and paste):
sudo service mysql stop && sudo killall -9 mysql && sudo killall -9 mysqld && sudo apt-get remove --purge mysql-server mysql-client mysql-common && sudo apt-get autoremove && sudo apt-get autoclean && sudo deluser mysql && sudo rm -rf /var/lib/mysql && sudo apt-get purge mysql-server-core-5.7 && sudo apt-get purge mysql-client-core-5.7 && sudo rm -rf /var/log/mysql && sudo rm -rf /etc/mysql

Building on @boulder_ruby's answer, this is what I'm looking for, assuming us_eco
contains the CSV table as from my gist.

us_eco.each do |row|
csvfile << row.values
end
end

In Rider, this would be Ctrl +Shift+Keypad *, 2
But!, you cannot use the number 2 on keypad, only number 2 on the top row of the keyboard would work.
Warning: GCC can optimize away an overflow check when compiling with -O2
.
The option -Wall
will give you a warning in some cases like
if (a + b < a) { /* Deal with overflow */ }
but not in this example:
b = abs(a);
if (b < 0) { /* Deal with overflow */ }
The only safe way is to check for overflow before it occurs, as described in the CERT paper, and this would be incredibly tedious to use systematically.
Compiling with -fwrapv
solves the problem, but disables some optimizations.
We desperately need a better solution. I think the compiler should issue a warning by default when making an optimization that relies on overflow not occurring. The present situation allows the compiler to optimize away an overflow check, which is unacceptable in my opinion.
Here's a way that allows for ties for the cut-off score.
author_count = Author.objects.count()
cut_off_score = Author.objects.order_by('-score').values_list('score')[min(30, author_count)]
top_authors = Author.objects.filter(score__gte=cut_off_score).order_by('last_name')
You may get more than 30 authors in top_authors this way and the min(30,author_count)
is there incase you have fewer than 30 authors.
The evaluation of condition
resulted in an NA
. The if
conditional must have either a TRUE
or FALSE
result.
if (NA) {}
## Error in if (NA) { : missing value where TRUE/FALSE needed
This can happen accidentally as the results of calculations:
if(TRUE && sqrt(-1)) {}
## Error in if (TRUE && sqrt(-1)) { : missing value where TRUE/FALSE needed
To test whether an object is missing use is.na(x)
rather than x == NA
.
See also the related errors:
Error in if/while (condition) { : argument is of length zero
Error in if/while (condition) : argument is not interpretable as logical
if (NULL) {}
## Error in if (NULL) { : argument is of length zero
if ("not logical") {}
## Error: argument is not interpretable as logical
if (c(TRUE, FALSE)) {}
## Warning message:

Let's be honest, we should probably consider using a Python Software Foundation maintained library:
https://docs.python.org/3/library/configparser.html
Config example: (ini format, but JSON available)
[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes
[bitbucket.org]
User = hg
[topsecret.server.com]
Port = 50022
ForwardX11 = no
Code example:
>>> import configparser
>>> config = configparser.ConfigParser()
>>> config.read('example.ini')
>>> config['DEFAULT']['Compression']
'yes'
>>> config['DEFAULT'].getboolean('MyCompression', fallback=True) # get_or_else
Making it globally-accessible:
import configpaser
class App:
__conf = None
@staticmethod
def config():
if App.__conf is None: # Read only once, lazy.
App.__conf = configparser.ConfigParser()
App.__conf.read('example.ini')
return App.__conf
if __name__ == '__main__':
App.config()['DEFAULT']['MYSQL_PORT']
# or, better:
App.config().get(section='DEFAULT', option='MYSQL_PORT', fallback=3306)
....
Downsides:
public String getLocalIpAddress() {
try {
for (Enumeration < NetworkInterface > en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration < InetAddress > enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
return inetAddress.getHostAddress().toString();
}
}
}
} catch (SocketException ex) {
Log.e(LOG_TAG, ex.toString());
}
return null;
}
I use the following function to get the current, full URL. This should work on IIS and Apache.
function get_current_url() {
$protocol = 'http';
if ($_SERVER['SERVER_PORT'] == 443 || (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on')) {
$protocol .= 's';
$protocol_port = $_SERVER['SERVER_PORT'];
} else {
$protocol_port = 80;
}
$host = $_SERVER['HTTP_HOST'];
$port = $_SERVER['SERVER_PORT'];
$request = $_SERVER['PHP_SELF'];
$query = isset($_SERVER['argv']) ? substr($_SERVER['argv'][0], strpos($_SERVER['argv'][0], ';') + 1) : '';
$toret = $protocol . '://' . $host . ($port == $protocol_port ? '' : ':' . $port) . $request . (empty($query) ? '' : '?' . $query);
return $toret;
}
Just summarizing an answer that was helpful to me (noting @erasmospunk's comment about using base-64 encoding). My goal was to have a short string that was mostly unique...
I'm no expert, so please correct this if it has any glaring errors (in Python again like the accepted answer):
import base64
import hashlib
import uuid
unique_id = uuid.uuid4()
# unique_id = UUID('8da617a7-0bd6-4cce-ae49-5d31f2a5a35f')
hash = hashlib.sha1(str(unique_id).encode("UTF-8"))
# hash.hexdigest() = '882efb0f24a03938e5898aa6b69df2038a2c3f0e'
result = base64.b64encode(hash.digest())
# result = b'iC77DySgOTjliYqmtp3yA4osPw4='
The result
here is using more than just hex characters (what you'd get if you used hash.hexdigest()
) so it's less likely to have a collision (that is, should be safer to truncate than a hex digest).
Note: Using UUID4 (random). See http://en.wikipedia.org/wiki/Universally_unique_identifier for the other types.
https://www.timcosta.io/angular-js-object-comparisons/
Angular is pretty magical the first time people see it. Automatic DOM updates when you update a variable in your JS, and the same variable will update in your JS file when someone updates its value in the DOM. This same functionality works across page elements, and across controllers.
The key to all of this is the $$hashKey Angular attaches to objects and arrays used in ng-repeats.
This $$hashKey causes a lot of confusion for people who are sending full objects to an API that doesn't strip extra data. The API will return a 400 for all of your requests, but that $$hashKey just wont go away from your objects.
Angular uses the $$hashKey to keep track of which elements in the DOM belong to which item in an array that is being looped through in an ng-repeat. Without the $$hashKey Angular would have no way to apply changes the occur in the JavaScript or DOM to their counterpart, which is one of the main uses for Angular.
Consider this array:
users = [
{
first_name: "Tim"
last_name: "Costa"
email: "[email protected]"
}
]
If we rendered that into a list using ng-repeat="user in users", each object in it would receive a $$hashKey for tracking purposes from Angular. Here are two ways to avoid this $$hashKey.
I tend to use this method
$errorlevel=error_reporting();
$errorlevel=error_reporting($errorlevel & ~E_DEPRECATED);
In this way I do not turn off accidentally something I need
You could configure this in your http-Header
httpResponse.setHeader("Content-Type", "application/force-download");
httpResponse.setHeader("Content-Disposition",
"attachment;filename="

The other way to tackle it is to use this code snippet:
JSON.parse(JSON.stringify(response)).data
This feels so wrong but it works
A very easy way to understand typedef of function pointer:
int add(int a, int b)
{
return (a+b);
}
typedef int (*add_integer)(int, int); //declaration of function pointer
int main()
{
add_integer addition = add; //typedef assigns a new variable i.e. "addition" to original function "add"
int c = addition(11, 11); //calling function via new variable
printf("%d",c);
return 0;
}
Compare also the difference between {}
and set()
with a single word argument.
>>> a = set('aardvark')
>>> a
{'d', 'v', 'a', 'r', 'k'}
>>> b = {'aardvark'}
>>> b
{'aardvark'}
but both a
and b
are sets of course.
If the array contains integers, the value cannot be NULL. NULL can be used if the array contains pointers.
SomeClass* myArray[2];
myArray[0] = new SomeClass();
myArray[1] = NULL;
if (myArray[0] != NULL) { // this will be executed }
if (myArray[1] != NULL) { // this will NOT be executed }
As http://en.cppreference.com/w/cpp/types/NULL states, NULL is a null pointer constant!

All of these options are fine, if you have the option to re-export the data.
But if you need to use an existing SQL file, and use a specific table from it, then this perl script in the TimeSheet blog, with enable you to extract the table to a separate SQL file, and then import it.
The original link is dead, so it is a good thing that someone has put it instead of the author, Jared Cheney, on GitHub, in this link.
+1 Database
Forms in your app can even re-translate themselves on the fly if corrections are made to the database.
We used a system where all the controls were mapped in an XML file (one per form) to language resource IDs, but all the IDs were in the database.
Basically, instead of having each control hold the ID (implementing an interface, or using the tag property in VB6), we used the fact that in .NET, the control tree was easily discoverable through reflection. A process when the form loaded would build the XML file if it was missing. The XML file would map the controls to their resource IDs, so this simply needed to be filled in and mapped to the database. This meant that there was no need to change the compiled binary if something was not tagged, or if it needed to be split to another ID (some words in English which might be used as both nouns and verbs might need to translate to two different words in the dictionary and not be re-used, but you might not discover this during initial assignment of IDs). But the fact is that the whole translation process becomes completely independent of your binary (every form has to inherit from a base form which knows how to translate itself and all its controls).
The only ones where the app gets more involved is when a phase with insertion points is used.
The database translation software was your basic CRUD maintenance screen with various workflow options to facilitate going through the missing translations, etc.
You can further simplify the accepted answer. Instead of typing out the enums as strings in xaml and doing more work in your converter than needed, you can explicitly pass in the enum value instead of a string representation, and as CrimsonX commented, errors get thrown at compile time rather than runtime:
<StackPanel>
<StackPanel.Resources>
<local:ComparisonConverter x:Key="ComparisonConverter" />
</StackPanel.Resources>
<RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum1}}" />
<RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum2}}" />
</StackPanel>
Then simplify the converter:
public class ComparisonConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value?.Equals(parameter);
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value?.Equals(true) == true ? parameter : Binding.DoNothing;
}
}
ConverterParameter={x:Static local:YourClass+YourNestedEnumType.Enum1}
Due to this Microsoft Connect Issue, however, the designer in VS2010 will no longer load stating "Type 'local:YourClass+YourNestedEnumType' was not found."
, but the project does compile and run successfully. Of course, you can avoid this issue if you are able to move your enum type to the namespace directly.
public class EnumToBooleanConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return ((Enum)value).HasFlag((Enum)parameter);
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value.Equals(true) ? parameter : Binding.DoNothing;
}
}
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
if (value == null) {
return false; // or return parameter.Equals(YourEnumType.SomeDefaultValue);
}
return value.Equals(parameter);
}
IsChecked
is a nullable type so returning Nullable<Boolean>
seems a reasonable solution.
For maintainability, I would attach the "blocking" handler on the element itself (in your case, the canvas).
theCanvas.onkeydown = function (e) {
if (e.key === 'ArrowUp' || e.key === 'ArrowDown') {
e.view.event.preventDefault();
}
}
Why not simply do window.event.preventDefault()
? MDN states:
window.event
is a proprietary Microsoft Internet Explorer property which is only available while a DOM event handler is being called. Its value is the Event object currently being handled.
Further readings:
You can pass multiple arguments like this.
List<object> arguments = new List<object>();
arguments.Add("first"); //argument 1
arguments.Add(new Object()); //argument 2
// ...
arguments.Add(10); //argument n
backgroundWorker.RunWorkerAsync(arguments);
private void worker_DoWork(object sender, DoWorkEventArgs e)
{
List<object> genericlist = e.Argument as List<object>;
//extract your multiple arguments from
//this list and cast them and use them.
}
My issue was displaying/hiding a mat-table on a button click using <ng-container *ngIf="myVar">. The 'loading' of the table was very slow with 300 records at 2-3 seconds.
The data is loaded using a subscribe in ngOnInit(), and is available and ready to be used in the template, however the 'loading' of the table in the template became increasingly slower with the increase in number of rows.
My solution was to replace the *ngIf with:
<div [style.display]="activeSelected ? 'block' : 'none'">
_x000D_
. Now the table loads instantly when the button is clicked.
After having really long discussion with CloudBees guys about properly maven packaging of such kind of JARs, they made an interesting good proposal for a solution:
Creation of a fake Maven project which attaches a pre-existing JAR as a primary artifact, running into belonged POM install:install-file execution. Here is an example of such kinf of POM:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<id>image-util-id</id>
<phase>install</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<file>${basedir}/file-you-want-to-include.jar</file>
<groupId>${project.groupId}</groupId>
<artifactId>${project.artifactId}</artifactId>
<version>${project.version}</version>
<packaging>jar</packaging>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
But in order to implement it, existing project structure should be changed. First, you should have in mind that for each such kind of JAR there should be created different fake Maven project (module). And there should be created a parent Maven project including all sub-modules which are : all JAR wrappers and existing main project. The structure could be :
root project (this contains the parent POM file includes all sub-modules with module XML element) (POM packaging)
JAR 1 wrapper Maven child project (POM packaging)
JAR 2 wrapper Maven child project (POM packaging)
main existing Maven child project (WAR, JAR, EAR .... packaging)
When parent running via mvn:install or mvn:packaging is forced and sub-modules will be executed. That could be concerned as a minus here, since project structure should be changed, but offers a non static solution at the end

Use saveas:
h=figure;
plot(x,y,'-bs','Linewidth',1.4,'Markersize',10);
% ...
saveas(h,name,'fig')
saveas(h,name,'jpg')
This way, the figure is plotted, and automatically saved to '.jpg' and '.fig'. You don't need to wait for the plot to appear and click 'save as' in the menu. Way to go if you need to plot/save a lot of figures.
If you really do not want to let the plot appear (it has to be loaded anyway, can't avoid that, else there is also nothing to save), you can hide it:
h=figure('visible','off')

One more solution as PyV8 seems to be unmaintained and dependent on the old version of libv8.
PyMiniRacer It's a wrapper around the v8 engine and it works with the new version and is actively maintained.
pip install py-mini-racer
from py_mini_racer import py_mini_racer
ctx = py_mini_racer.MiniRacer()
ctx.eval("""
function escramble_758(){
var a,b,c
a='+1 '
b='84-'
a+='425-'
b+='7450'
c='9'
return a+c+b;
}
""")
ctx.call("escramble_758")
And yes, you have to replace document.write
with return
as others suggested
You need to make the object first, then use []
to set it.
var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);
UPDATE 2018:
If you're able to use ES6 and Babel, you can use this new feature:
{
[yourKeyVariable]: someValueArray,
}
The following method may work:
git rebase HEAD master
git checkout master
This will rebase your current HEAD changes on top of the master. Then you can switch the branch.
Alternative way is to checkout the branch first:
git checkout master
Then Git should display SHA1 of your detached commits, then you can cherry pick them, e.g.
git cherry-pick YOURSHA1
Or you can also merge the latest one:
git merge YOURSHA1
To see all of your commits from different branches (to make sure you've them), run: git reflog
.
To select the duplicates only the query format can be:
SELECT GroupFunction(column1), GroupFunction(column2),...,
COUNT(column1), column1, column2...
FROM our_table
GROUP BY column1, column2, column3...
HAVING COUNT(column1) > 1
So the correct query as per other suggestion is:
DELETE FROM tablename a
WHERE a.ROWID > ANY (SELECT b.ROWID
FROM tablename b
WHERE a.fieldname = b.fieldname
AND a.fieldname2 = b.fieldname2
AND ....so on.. to identify the duplicate rows....)
This query will keep the oldest record in the database for the criteria chosen in the WHERE CLAUSE
.

Warning: Don't do this if you've already pushed
You want to do:
git reset HEAD~
If you don't want the changes and blow everything away:
git reset --hard HEAD~
I had the same problem and this is how I suggest you fix it:
Run:
mvn dependency:list
and read carefully if there are any warning messages indicating that for some dependencies there will be no transitive dependencies available.
If yes, re-run it with -X flag:
mvn dependency:list -X
to see detailed info what is maven complaining about (there might be a lot of output for -X flag)
In my case there was a problem in dependent maven module pom.xml - with managed dependency. Although there was a version for the managed dependency defined in parent pom, Maven was unable to resolve it and was complaining about missing version in the dependent pom.xml
So I just configured the missing version and the problem disappeared.
You need to use the m
flag:
multiline; treat beginning and end characters (^ and $) as working over multiple lines (i.e., match the beginning or end of each line (delimited by \n or \r), not only the very beginning or end of the whole input string)
Also put the *
in the right place:
"DATE:20091201T220000\r\nSUMMARY:Dad's birthday".match(/^SUMMARY\:(.*)$/gm);
//------------------------------------------------------------------^ ^
//-----------------------------------------------------------------------|
raw_input
returns a string (a sequence of characters). In Python, multiplying a string and a float makes no defined meaning (while multiplying a string and an integer has a meaning: "AB" * 3
is "ABABAB"
; how much is "L" * 3.14
? Please do not reply "LLL|"
). You need to parse the string to a numerical value.
You might want to try:
salesAmount = float(raw_input("Insert sale amount here\n"))
Another reason + solution
I run into this error ("package XXX is not available for R version X.X.X") when trying to install pkgdown in my RStudio on my company's HPC.
Turns out, the CRAN snapshot they have on the HPC is from Jan. 2018 (almost 2 years old) and indeed pkgdown did not exist then. That was meant to control the source of packages for layman users, but as a developer, you can in most cases change that by:
## checking the specific repos you currently have
getOption("repos")
## updating your CRAN snapshot to a newer date
r <- getOption("repos")
r["newCRAN"] <- "https://cran.microsoft.com/snapshot/*2019-11-07*/"
options(repos = r)
## add newCRAN to repos you can use
setRepositories()
If you know what you are doing and may need more than one package that might not be available in your system's CRAN, you can set this up in your project .Rprofile
.
If it's just one package, maybe just use install.packages("package name", repos = "a newer CRAN than your company's archaic CRAN snapshot")
.
if you are talking about in the reference of String Class. so you can use
subString/split
for Explode & use String
concate
for Implode.
They've now deprecated click(), so best to go with on('click')
Your best bet is to use
table.YourClass tr:hover td {
background-color: #FEFEFE;
}
Rows aren't fully support for background color but cells are, using the combination of :hover and the child element will yield the results you need.
You may consider declaring the variables with moudule level scope. Module-level variable is available to all of the procedures in that module, but it is not available to procedures in other modules

Please copy the below code into any module, save the workbook and then run the code.
Here is what code does
The sample subroutine sets the folder path & later the file path. Kindly set them accordingly before you run the code.
I have added a function IsWorkBookOpen to check if workbook is already then set the workbook variable the workbook name else open the workbook which will be assigned to workbook variable accordingly.
Dim wbA As Workbook
Dim wbB As Workbook
Sub MySubRoutine()
Dim folderPath As String, fileNm1 As String, fileNm2 As String, filePath1 As String, filePath2 As String
folderPath = ThisWorkbook.Path & "\"
fileNm1 = "file1.xlsx"
fileNm2 = "file2.xlsx"
filePath1 = folderPath & fileNm1
filePath2 = folderPath & fileNm2
If IsWorkBookOpen(filePath1) Then
Set wbA = Workbooks(fileNm1)
Else
Set wbA = Workbooks.Open(filePath1)
End If
If IsWorkBookOpen(filePath2) Then
Set wbB = Workbooks.Open(fileNm2)
Else
Set wbB = Workbooks.Open(filePath2)
End If
' your code here
End Sub
Function IsWorkBookOpen(FileName As String)
Dim ff As Long, ErrNo As Long
On Error Resume Next
ff = FreeFile()
Open FileName For Input Lock Read As #ff
Close ff
ErrNo = Err
On Error GoTo 0
Select Case ErrNo
Case 0: IsWorkBookOpen = False
Case 70: IsWorkBookOpen = True
Case Else: Error ErrNo
End Select
End Function
Using Prompt to select the file use below code.
Dim wbA As Workbook
Dim wbB As Workbook
Sub MySubRoutine()
Dim folderPath As String, fileNm1 As String, fileNm2 As String, filePath1 As String, filePath2 As String
Dim filePath As String
cmdBrowse_Click filePath, 1
filePath1 = filePath
'reset the variable
filePath = vbNullString
cmdBrowse_Click filePath, 2
filePath2 = filePath
fileNm1 = GetFileName(filePath1, "\")
fileNm2 = GetFileName(filePath2, "\")
If IsWorkBookOpen(filePath1) Then
Set wbA = Workbooks(fileNm1)
Else
Set wbA = Workbooks.Open(filePath1)
End If
If IsWorkBookOpen(filePath2) Then
Set wbB = Workbooks.Open(fileNm2)
Else
Set wbB = Workbooks.Open(filePath2)
End If
' your code here
End Sub
Function IsWorkBookOpen(FileName As String)
Dim ff As Long, ErrNo As Long
On Error Resume Next
ff = FreeFile()
Open FileName For Input Lock Read As #ff
Close ff
ErrNo = Err
On Error GoTo 0
Select Case ErrNo
Case 0: IsWorkBookOpen = False
Case 70: IsWorkBookOpen = True
Case Else: Error ErrNo
End Select
End Function
Private Sub cmdBrowse_Click(ByRef filePath As String, num As Integer)
Dim fd As FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
fd.AllowMultiSelect = False
fd.Title = "Select workbook " & num
fd.InitialView = msoFileDialogViewSmallIcons
Dim FileChosen As Integer
FileChosen = fd.Show
fd.Filters.Clear
fd.Filters.Add "Excel macros", "*.xlsx"
fd.FilterIndex = 1
If FileChosen <> -1 Then
MsgBox "You chose cancel"
filePath = ""
Else
filePath = fd.SelectedItems(1)
End If
End Sub
Function GetFileName(fullName As String, pathSeparator As String) As String
Dim i As Integer
Dim iFNLenght As Integer
iFNLenght = Len(fullName)
For i = iFNLenght To 1 Step -1
If Mid(fullName, i, 1) = pathSeparator Then Exit For
Next
GetFileName = Right(fullName, iFNLenght - i)
End Function
A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.
For instance, place your property file in a new folder src/main/config, and add the following to your pom:
<build>
<resources>
<resource>
<directory>src/main/config</directory>
</resource>
</resources>
</build>
From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<excludes>
<exclude>my-config.properties</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).
Convert everything to everything (bool,string,enum,etc):
public class EverythingConverterValue
{
public object ConditionValue { get; set; }
public object ResultValue { get; set; }
}
public class EverythingConverterList : List<EverythingConverterValue>
{
}
public class EverythingConverter : IValueConverter
{
public EverythingConverterList Conditions { get; set; } = new EverythingConverterList();
public object NullResultValue { get; set; }
public object NullBackValue { get; set; }
public object Convert(object value, Type targetType,
object parameter, CultureInfo culture)
{
return Conditions.Where(x => x.ConditionValue.Equals(value)).Select(x => x.ResultValue).FirstOrDefault() ?? NullResultValue;
}
public object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
return Conditions.Where(x => x.ResultValue.Equals(value)).Select(x => x.ConditionValue).FirstOrDefault() ?? NullBackValue;
}
}

Maybe you should use a display inline-block too:
.circle {
display: inline-block;
height: 25px;
width: 25px;
background-color: #bbb;
border-radius: 50%;
z-index: -1;
}
