Try one of these:
gdb -p 12271
gdb /path/to/exe 12271
gdb /path/to/exe
(gdb) attach 12271
This is a way:
Bash:
max=10
for i in $(bash -c "echo {2..${max}}"); do echo $i; done
The above Bash way will work for ksh
and zsh
too, when bash -c
is replaced with ksh -c
or zsh -c
respectively.
Note: for i in {2..${max}}; do echo $i; done
works in zsh
and ksh
.
It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null
.
Given your statement:
img1.ImageUrl = ConfigurationManager
.AppSettings
.Get("Url")
.Replace("###", randomString)
+ Server.UrlEncode(
((System.Web.UI.MobileControls.Form)Page
.FindControl("mobileForm"))
.Title);
I'm guessing either the call to AppSettings.Get("Url")
is returning null because the value isn't found or the call to Page.FindControl("mobileForm")
is returning null because the control isn't found.
You could easily break this out into multiple statements to solve the problem:
var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
as System.Web.UI.MobileControls.Form;
if(configUrl != null && mobileFormControl != null)
{
img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}
The currently accepted answer is incorrect - document.documentElement.scrollTop
always returns 0 on Chrome. This is because WebKit uses body
for keeping track of scrolling, whereas Firefox and IE use html
.
To get the current position, you want:
document.documentElement.scrollTop || document.body.scrollTop
You can set the current position to 1000px down the page like so:
document.documentElement.scrollTop = document.body.scrollTop = 1000;
Or, using jQuery (animate it while you're at it!):
$("html, body").animate({ scrollTop: "1000px" });
Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

this does not refresh your component I solved the problem by using Vux create a module for vuex "page"
export const state = {
currentScrollY: 0,
};
export const getters = {
currentScrollY: s => s.currentScrollY
};
export const actions = {
setCurrentScrollY ({ commit }, y) {
commit('setCurrentScrollY', {y});
},
};
export const mutations = {
setCurrentScrollY (s, {y}) {
s.currentScrollY = y;
},
};
export default {
state,
getters,
actions,
mutations,
};
in App.vue :
created() {
window.addEventListener("scroll", this.handleScroll);
},
destroyed() {
window.removeEventListener("scroll", this.handleScroll);
},
methods: {
handleScroll () {
this.$store.dispatch("page/setCurrentScrollY", window.scrollY);
}
},
in your component :
computed: {
currentScrollY() {
return this.$store.getters["page/currentScrollY"];
}
},
watch: {
currentScrollY(val) {
if (val > 100) {
this.isVisibleStickyMenu = true;
} else {
this.isVisibleStickyMenu = false;
}
}
},
and it works great.
Use:
(/bookstore/book[@location='US'])[1]
This will first get the book elements with the location attribute equal to 'US'. Then it will select the first node from that set. Note the use of parentheses, which are required by some implementations.
Note, this is not the same as /bookstore/book[1][@location='US']
unless the first element also happens to have that location attribute.
ERROR! MySQL server PID file could not be found!
This might be due to issues with disk space, disk inode usage or innodb corruption which may lead to the error.
The issue was with the pid file and the solution was:
SSH login to server as a root
Create directory /var/run/mysql
mkdir /var/run/mysql
3) Create a file with name as mysqld.pid
touch mysqld.pid
Change its ownership and group to mysql:mysql
chown mysql:mysql mysqld.pid
Restart MySQL service
Done!

I tried to add the following options in the /etc/docker/daemon.json. (I used CentOS7)
"add-registry": ["192.168.100.100:5001"],

after that, restarted docker daemon. And it's working without docker.io. I hope this someone will be helpful.
The command is lowercase: touch filename
.
Keep in mind that touch
will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch
If you always want an empty file, one way to do so would be to use:
echo "" > filename
Use:
android:screenOrientation="portrait"
Just write this line in your application's manifest file in each activity which you want to show in portrait mode only.
I hit this issue with Ubuntu 18.04 and none of the previous answers solved it. Eventually I succeeded by installing devtools
with the package manager itself:
sudo apt install r-cran-devtools
If you're like me and run on a Linux server without root privileges and there isn't any xclip or GPM you could workaround this issue by just using a temporary file. For example:
$ echo "Hello, World!" > ~/clip
$ echo `cat ~/clip`
Hello, World!
If anyone came to this question looking for ways to add multiple parameters at the same time (my case), you can use .params
with a MultivalueMap instead of adding each .param
:
LinkedMultiValueMap<String, String> requestParams = new LinkedMultiValueMap<>()
requestParams.add("id", "1");
requestParams.add("name", "john");
requestParams.add("age", "30");
mockMvc.perform(get("my/endpoint").params(requestParams)).andExpect(status().isOk())
select convert(varchar(8), getdate(), 3)
simply use this for dd/mm/yy and this
select convert(varchar(8), getdate(), 1)
for mm/dd/yy
Just found out the hard way that it is
SELECT 1 FROM DUAL
for MaxDB as well.
The col
argument in the plot
function assign colors automatically to a vector of integers. If you convert iris$Species
to numeric, notice you have a vector of 1,2 and 3s So you can apply this as:
plot(iris$Sepal.Length, iris$Sepal.Width, col=as.numeric(iris$Species))
Suppose you want red, blue and green instead of the default colors, then you can simply adjust it:
plot(iris$Sepal.Length, iris$Sepal.Width, col=c('red', 'blue', 'green')[as.numeric(iris$Species)])
You can probably see how to further modify the code above to get any unique combination of colors.
There is no portable way to read raw characters from a Java console.
Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.
Suppose: SqlConnection connectionObj = new SqlConnection()
for : connectionObj.ConnectionString -> use server name : (localdb)\\MSSQLLocalDB.
Note: Double back slash
for : App.config -> use server name : (localdb)\MSSQLLocalDB
Note: Single back slash
You can use sort() function. sort() exists in algorithm header file
#include<bits/stdc++.h>
using namespace std;
int main()
{
ios::sync_with_stdio(false);
string str = "sharlock";
sort(str.begin(), str.end());
cout<<str<<endl;

Google Maps API v3:
I initialized Google Map and added markers to it. Later, I wanted to retrieve all markers and did it simply by accessing the map property "markers".
var map = new GMaps({
div: '#map',
lat: 40.730610,
lng: -73.935242,
});
var myMarkers = map.markers;
You can loop over it and access all Marker methods listed at Google Maps Reference.
my solution is
navigationText: ["", ""]
full code is below:
var owl1 = $("#main-demo");
owl1.owlCarousel({
navigation: true, // Show next and prev buttons
slideSpeed: 300,
pagination:false,
singleItem: true, transitionStyle: "fade",
navigationText: ["", ""]
});// Custom Navigation Events
owl1.trigger('owl.play', 4500);

Apparently, action
was required prior to HTML5 (and #
was just a stand in), but you no longer have to use it.
See The Action Attribute:
When specified with no attributes, as below, the data is sent to the same page that the form is present on:
<form>
You can also simply use http://maps.google.com/maps as your URI
String uri = "http://maps.google.com/maps?saddr=" + sourceLatitude + "," + sourceLongitude + "&daddr=" + destinationLatitude + "," + destinationLongitude;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(intent);
or you can make sure that the Google Maps app only is used, this stops the intent filter (dialog) from appearing, by using
intent.setPackage("com.google.android.apps.maps");
like so:
String uri = "http://maps.google.com/maps?saddr=" + sourceLatitude + "," + sourceLongitude + "&daddr=" + destinationLatitude + "," + destinationLongitude;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);
or you can add labels to the locations by adding a string inside parentheses after each set of coordinates like so:
String uri = "http://maps.google.com/maps?saddr=" + sourceLatitude + "," + sourceLongitude + "(" + "Home Sweet Home" + ")&daddr=" + destinationLatitude + "," + destinationLongitude + " (" + "Where the party is at" + ")";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);
To use the users current location as the starting point (unfortunately I haven't found a way to label the current location) then just drop off the saddr
parameter as follows:
String uri = "http://maps.google.com/maps?daddr=" + destinationLatitude + "," + destinationLongitude + " (" + "Where the party is at" + ")";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);
For completeness, if the user doesn't have the maps app installed then it's going to be a good idea to catch the ActivityNotFoundException, as @TonyQ states, then we can start the activity again without the maps app restriction, we can be pretty sure that we will never get to the Toast at the end since an internet browser is a valid application to launch this url scheme too.
String uri = "http://maps.google.com/maps?daddr=" + 12f + "," + 2f + " (" + "Where the party is at" + ")";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setPackage("com.google.android.apps.maps");
try
{
startActivity(intent);
}
catch(ActivityNotFoundException ex)
{
try
{
Intent unrestrictedIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(unrestrictedIntent);
}
catch(ActivityNotFoundException innerEx)
{
Toast.makeText(this, "Please install a maps application", Toast.LENGTH_LONG).show();
}
}
EDIT:
For directions, a navigation intent is now supported with google.navigation
Uri navigationIntentUri = Uri.parse("google.navigation:q=" + 12f + "," + 2f);
Intent mapIntent = new Intent(Intent.ACTION_VIEW, navigationIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);
Because the statement defining obj
hasn't finished, key1
doesn't exist yet. Consider this solution:
var obj = { key1: "it" };
obj.key2 = obj.key1 + ' ' + 'works!';
// obj.key2 is now 'it works!'
If you are not allowed to change the buffer limit at the server level, you will need to use the <%Response.Buffer = False%> method.
HOWEVER, if you are still getting this error and have a large table on the page, the culprit may be table itself. By design, some versions of Internet Explorer will buffer the entire content between before it is rendered to the page. So even if you are telling the page to not buffer the content, the table element may be buffered and causing this error.
Some alternate solutions may be to paginate the table results, but if you must display the entire table and it has thousands of rows, throw this line of code in the middle of the table generation loop: <% Response.Flush %>. For speed considerations, you may also want to consider adding a basic counter so that the flush only happens every 25 or 100 lines or so.
Drawbacks of not buffering the output:

It's ridiculous how bad Mysql and MariaDB are optimized when it comes to inserts. I tested mysql 5.7 and mariadb 10.3, no real difference on those.
I've tested this on a server with NVME disks, 70,000 IOPS, 1.1 GB/sec seq throughput and that's possible full duplex (read and write).
The server is a high performance server as well.
Gave it 20 GB of ram.
The database completely empty.
The speed I receive was 5000 inserts per second when doing multi row inserts (tried it with 1MB up to 10MB chunks of data)
Now the clue:
If I add another thread and insert into the SAME tables I suddenly have 2x5000 /sec.
One more thread and I have 15000 total /sec
Consider this: When doing ONE thread inserts it means you can sequentially write to the disk (with exceptions to indexes). When using threads you actually degrade the possible performance because it now needs to do a lot more random accesses. But reality check shows mysql is so badly optimized that threads help a lot.
The real performance possible with such a server is probably millions per second, the CPU is idle the disk is idle.
The reason is quite clearly that mariadb just as mysql has internal delays.
You can try the following solution:
curl -v -X POST -d @payload.xml https://<API Path> -k -H "Content-Type: application/xml;charset=utf-8"
This should work for you:
IF NOT EXIST "\path\to\your\folder" md \path\to\your\folder
However, there is another method, but it may not be 100% useful:
md \path\to\your\folder >NUL 2>NUL
This one creates the folder, but does not show the error output if folder exists. I highly recommend that you use the first one. The second one is if you have problems with the other.

This article has a good discussion on this issue. You can use
SELECT *
FROM Y
INNER JOIN X ON EXISTS(SELECT X.QID
INTERSECT
SELECT y.QID);
See https://code.angularjs.org/1.4.10/docs/api/ngRoute/provider/$routeProvider
[reloadOnSearch=true] - {boolean=} - reload route when only $location.search() or $location.hash() changes.
Setting this to false did the trick without all of the above for me.
I decided I didn't want to use a pickle because I wanted to be able to open the text file and change its contents easily during testing. Therefore, I did this:
score = [1,2,3,4,5]
with open("file.txt", "w") as f:
for s in score:
f.write(str(s) +"\n")
score = []
with open("file.txt", "r") as f:
for line in f:
score.append(int(line.strip()))
So the items in the file are read as integers, despite being stored to the file as strings.
I believe the correct answer is that their values are undefined. Often, they are initialized to 0 when running debug versions of the code. This is usually not the case when running release versions.
This is the activity the tools UI editor uses to render your layout preview. It is documented here:
This attribute declares which activity this layout is associated with by default. This enables features in the editor or layout preview that require knowledge of the activity, such as what the layout theme should be in the preview and where to insert onClick handlers when you make those from a quickfix
test[,sort(names(test))]
sort on names of columns can work easily.
I had the same problem. I use the MSSQL Server Management Studio 2017 and solved this problem using these steps:

Value: <c:out value="${entry.value}"/>
</c:forEach>

If I have open a package in BIDS ("Business Intelligence Development Studio", the tool you use to design the packages), and do not select any item in it, I have a "Properties" pane in the bottom right containing - among others, the MaximumErrorCount
property. If you do not see it, maybe it is minimized and you have to open it (have a look at tabs in the right).
If you cannot find it this way, try the menu: View/Properties Window.
Or try the F4 key.
Currently, Macports has many more packages (~18.6 K) than there are Homebrew formulae (~3.1K), owing to its maturity. Homebrew is slowly catching up though.
Macport packages tend to be maintained by a single person.
Macports can keep multiple versions of packages around, and you can enable or disable them to test things out. Sometimes this list can get corrupted and you have to manually edit it to get things back in order, although this is not too hard.
Both package managers will ask to be regularly updated. This can take some time.
Note: you can have both package managers on your system! It is not one or the other. Brew might complain but Macports won't.
Also, if you are dealing with python or ruby packages, use a virtual environment wherever possible.
In Angular you can define event listeners
like in the example below:
<!-- Here you can call public methods from parental component -->
<input (change)="method_name()">
Asterisk symbol (*) is used to check values in the array, not the array itself.
$validator = Validator::make($request->all(), [
"names" => "required|array|min:3",
"names.*" => "required|string|distinct|min:3",
]);
In the example above:
EDIT: Since Laravel 5.5 you can call validate() method directly on Request object like so:
$data = $request->validate([
"name" => "required|array|min:3",
"name.*" => "required|string|distinct|min:3",
]);
A temporary solution if you don't want to get into the x

Following worked for me.
plt.title('Capital Expenditure\n') # Add a next line after your title
kudos.
Just hold cursor over member you interested in, and see tooltip - it will show memeber's type:
By default, a vagrant box doesn't have any ip address. In order to find the IP address, you simply assign the IP address in your Vagrantfile
then call vagrant reload
If you just need to access a vagrant machine from only the host machine, setting up a "private network" is all you need. Either uncomment the appropriate line in a default Vagrantfile
, or add this snippet. If you want your VM to appear at 172.30.1.5
it would be the following:
config.vm.network "private_network", ip: "172.30.1.5"
Learn more about private networks. https://www.vagrantup.com/docs/networking/private_network.html
If you need vagrant to be accessible outside your host machine, for instance for developing against a mobile device such as iOS or Android, you have to enable a public network you can use either static IP, such as 192.168.1.10
, or DHCP.
config.vm.network "public_network", ip: "192.168.1.10"
Learn more about configuring a public network https://www.vagrantup.com/docs/networking/public_network.html
as above, but qualitatively:
private - least access, best encapsulation
protected - some access, moderate encapsulation
public - full access, no encapsulation
the less access you provide the fewer implementation details leak out of your objects. less of this sort of leakage means more flexibility (aka "looser coupling") in terms of changing how an object is implemented without breaking clients of the object. this is a truly fundamental thing to understand.

Using Visual Studio
This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).
Using Process Explorer
If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)
Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.
Programmatically
Check this SO question that explains how to do it.
Try using a format like %d.%02d
int iAmount = 10050;
printf("The number with fake decimal point is %d.%02d", iAmount/100, iAmount%100);
Another approach is to type cast it to double before printing it using %f like this:
printf("The number with fake decimal point is %0.2f", (double)(iAmount)/100);
My 2 cents :)
Try following code works for me under Linux chrome environment. Before running make sure jquery is attached to the document.
$(document).ready(function()
{
$(window).bind("beforeunload", function() {
return confirm("Do you really want to close?");
});
});
For simple follow following steps:
It should show following picture:
../../../includes/boot.inc.php
Each instance of ../
means up/back one directory.
Here's a trick to easily check if the schema already exists, and then create it, in it's own batch, to avoid the error message of trying to create a schema when it's not the only command in a batch.
IF NOT EXISTS (SELECT schema_name
FROM information_schema.schemata
WHERE schema_name = 'newSchemaName' )
BEGIN
EXEC sp_executesql N'CREATE SCHEMA NewSchemaName;';
END
When dealing with situations where I don't exactly know what type of exception might come out of a method, a little "trick" I like to do is to recover the Exception's class name and add it to the error log so there is more information.
try
{
<code>
} catch ( Exception caughtEx )
{
throw new Exception("Unknown Exception Thrown: "
+ "\n Type: " + caughtEx.GetType().Name
+ "\n Message: " + caughtEx.Message);
}
I do vouch for always handling Exceptions types individually, but the extra bit of info can be helpful, specially when dealing with code from people who love to capture catch-all generic types.
First of all you need to extract the path with something like this:
$("a#myLink").attr("href");
Then take a look at this plugin: http://plugins.jquery.com/project/query-object
It will help you handle all kinds of querystring things you want to do.

I didn't see this solution. I find it simpler for where I currently am in software development:
public static void PrintFigure(int shapeSize)
{
string figure = "\\/";
for (int loopTwo = 1; loopTwo <= shapeSize - 1; loopTwo++)
{
Console.Write($"{figure}");
}
}
You can encrypt your SQLite database with the SEE addon. This way you prevent unauthorized access/modification.
Quoting SQLite documentation:
The SQLite Encryption Extension (SEE) is an enhanced version of SQLite that encrypts database files using 128-bit or 256-Bit AES to help prevent unauthorized access or modification. The entire database file is encrypted so that to an outside observer, the database file appears to contain white noise. There is nothing that identifies the file as an SQLite database.
You can find more info about this addon in this link.

Following Step to to enable disable ARC
Select Xcode project Go to targets Select the Build phases section Inside the build phases section select the compile sources. Select the file which you do not want to disable ARC and add -fno-objc-arc
Here is the one-liner for fedora or other rpm distros (based on @barraponto tips):
find /usr/lib/python2.7/site-packages -maxdepth 2 -name __init__.py | xargs rpm -qf | grep 'not owned by any package'
Append this to the previous command to get cleaner output:
| sed -r 's:.*/(\w+)/__.*:\1:'
If you use PHP's default session handling, the only way to reliably change the session duration in all platforms is to change php.ini. That's because in some platforms, garbage collection is implemented through a script that runs every certain time (a cron script) that reads directly from php.ini, and therefore any attempts at changing it at run time, e.g. via ini_set()
, are unreliable and most likely won't work.
For example, in Debian Linux systems, PHP's internal garbage collection is disabled by setting session.gc_probability=0
by default in the configuration, and is instead done via /etc/cron.d/php, which runs at XX:09 and XX:39 (that is, every half hour). This cron job looks for sessions older than the session.gc_maxlifetime specified in the configuration, and if any are found, they are deleted. As a consequence, in these systems ini_set('session.gc_maxlifetime', ...)
is ignored. That also explains why in this question: PHP sessions timing out too quickly, the OP had problems in one host but the problems ceased when switching to a different host.
So, given that you don't have access to php.ini, if you want to do it portably, using the default session handling is not an option. Apparently, extending the cookie lifetime was enough for your host, but if you want a solution that works reliably even if you switch hosts, you have to use a different alternative.
Available alternative methods include:
Set a different session (save) handler in PHP to save your sessions in a different directory or in a database, as specified in PHP: Custom Session Handlers (PHP manual), so that the cron job doesn't reach it, and only PHP's internal garbage collection takes place. This option probably can make use of ini_set()
to set session.gc_maxlifetime but I prefer to just ignore the maxlifetime parameter in my gc()
callback and determine maximum lifetime on my own.
Completely forget about PHP internal session handling and implement your own session management. This method has two main disadvantages: you will need your own global session variables, so you lose the advantage of the $_SESSION
superglobal, and it needs more code thus there are more opportunities for bugs and security flaws. Most importantly, the session identifier should be generated out of cryptographically secure random or pseudorandom numbers to avoid session ID predictability (leading to possible session hijacking), and that is not so easy to do with PHP portably. The main advantage is that it will work consistently in all platforms and you have full control over the code. That's the approach taken e.g. by the phpBB forum software (at least version 1; I'm not sure about more recent versions).
There is an example of (1) in the documentation for session_set_save_handler()
. The example is long but I'll reproduce it here, with the relevant modifications necessary to extend the session duration. Note the inclusion of session_set_cookie_params()
to increase the cookie lifetime as well.
<?php
class FileSessionHandler
{
private $savePath;
private $lifetime;
function open($savePath, $sessionName)
{
$this->savePath = 'my_savepath'; // Ignore savepath and use our own to keep it safe from automatic GC
$this->lifetime = 3600; // 1 hour minimum session duration
if (!is_dir($this->savePath)) {
mkdir($this->savePath, 0777);
}
return true;
}
function close()
{
return true;
}
function read($id)
{
return (string)@file_get_contents("$this->savePath/sess_$id");
}
function write($id, $data)
{
return file_put_contents("$this->savePath/sess_$id", $data) === false ? false : true;
}
function destroy($id)
{
$file = "$this->savePath/sess_$id";
if (file_exists($file)) {
unlink($file);
}
return true;
}
function gc($maxlifetime)
{
foreach (glob("$this->savePath/sess_*") as $file) {
if (filemtime($file) + $this->lifetime < time() && file_exists($file)) { // Use our own lifetime
unlink($file);
}
}
return true;
}
}
$handler = new FileSessionHandler();
session_set_save_handler(
array($handler, 'open'),
array($handler, 'close'),
array($handler, 'read'),
array($handler, 'write'),
array($handler, 'destroy'),
array($handler, 'gc')
);
// the following prevents unexpected effects when using objects as save handlers
register_shutdown_function('session_write_close');
session_set_cookie_params(3600); // Set session cookie duration to 1 hour
session_start();
// proceed to set and retrieve values by key from $_SESSION
Approach (2) is more complicated; basically, you have to re-implement all session functions on your own. I won't go into details here.
I would also like to add something here that if you load desired form that contain tooltip controll before the program's run then tool tip control on that form will not work as described below...
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
objfrmmain = new Frm_Main();
Showtop();//this is procedure in program.cs to load an other form, so if that contain's tool tip control then it will not work
Application.Run(objfrmmain);
}
so I solved this problem by puting following code in Fram_main_load event procedure like this
private void Frm_Main_Load(object sender, EventArgs e)
{
Program.Showtop();
}
"Most recent" could have two meanings in terms of git.
You could mean, "which tag has the creation date latest in time", and most of the answers here are for that question. In terms of your question, you would want to return tag c
.
Or you could mean "which tag is the closest in development history to some named branch", usually the branch you are on, HEAD
. In your question, this would return tag a
.
These might be different of course:
A->B->C->D->E->F (HEAD)
\ \
\ X->Y->Z (v0.2)
P->Q (v0.1)
Imagine the developer tag'ed Z
as v0.2
on Monday, and then tag'ed Q
as v0.1
on Tuesday. v0.1
is the more recent, but v0.2
is closer in development history to HEAD, in the sense that the path it is on starts at a point closer to HEAD.
I think you usually want this second answer, closer in development history. You can find that out by using git log v0.2..HEAD
etc for each tag. This gives you the number of commits on HEAD since the path ending at v0.2
diverged from the path followed by HEAD.
Here's a Python script that does that by iterating through all the tags running this check, and then printing out the tag with fewest commits on HEAD since the tag path diverged:
https://github.com/MacPython/terryfy/blob/master/git-closest-tag
git describe
does something slightly different, in that it tracks back from (e.g.) HEAD to find the first tag that is on a path back in the history from HEAD. In git terms, git describe
looks for tags that are "reachable" from HEAD. It will therefore not find tags like v0.2
that are not on the path back from HEAD, but a path that diverged from there.
TimeUnit is an enum, so you can't create a new one.
The following will convert 1000000000000ns to seconds.
TimeUnit.NANOSECONDS.toSeconds(1000000000000L);
Here's an alternative that works well for readability if you have the Binding in the middle of the string or multiple bindings:
<TextBlock>
<Run Text="Temperature is "/>
<Run Text="{Binding CelsiusTemp}"/>
<Run Text="°C"/>
</TextBlock>
<!-- displays: 0°C (32°F)-->
<TextBlock>
<Run Text="{Binding CelsiusTemp}"/>
<Run Text="°C"/>
<Run Text=" ("/>
<Run Text="{Binding Fahrenheit}"/>
<Run Text="°F)"/>
</TextBlock>
I was having this problem after I got the blue screen of death while running my emulator. Here's my solution (for Windows at least). My solution is too completely re-install the AVD. The problem with the normal un-installation process for Android Studio is that it doesn't remove everything, so if your AVD files are corrupted, they will remain corrupted on re-install.
In order to fix this, I deleted two directories:
C:\Users\(My Username)\.Android
and
C:\Users\(My Username)\.AndroidStudio3.1
Then I re-ran in the installer.
I think this is the most foolproof solution if your emulator was previously working because it forces a complete refresh of the AVD component of Android Studio.

I suspect you might not have Customer.equals()
implemented properly (or at all).
List.contains()
uses equals()
to verify whether any of its elements is identical to the object passed as parameter. However, the default implementation of equals
tests for physical identity, not value identity. So if you have not overwritten it in Customer
, it will return false for two distinct Customer objects having identical state.
Here are the nitty-gritty details of how to implement equals
(and hashCode
, which is its pair - you must practically always implement both if you need to implement either of them). Since you haven't shown us the Customer class, it is difficult to give more concrete advice.
As others have noted, you are better off using a Set rather than doing the job by hand, but even for that, you still need to implement those methods.
Try:
ls -1 | grep -E "\.tar\.gz$" | xargs -n 1 tar xvfz
Then Try:
ls -1 | grep -E "\.tar\.gz$" | xargs -n 1 rm
This will untar all .tar.gz files in the current directory and then delete all the .tar.gz files. If you want an explanation, the "|" takes the stdout of the command before it, and uses that as the stdin of the command after it. Use "man command" w/o the quotes to figure out what those commands and arguments do. Or, you can research online.
We also need to mention default schema for SQSERVER: dbo
<property name="hibernate.default_schema">dbo</property>
Tested with hibernate 4
Previous answers advise using the tarfile
Python module for creating a .tar.gz
file in Python. That's obviously a good and Python-style solution, but it has serious drawback in speed of the archiving. This question mentions that tarfile
is approximately two times slower than the tar
utility in Linux. According to my experience this estimation is pretty correct.
So for faster archiving you can use the tar
command using subprocess
module:
subprocess.call(['tar', '-czf', output_filename, file_to_archive])
let obj = {"a": 3, "b": 2, "6": "a"}
Object.keys(obj).map((item) => {console.log("item", obj[item])})
// a
// 3
// 2
You can strip non-digits and do a comparison. Here's a demo script:
for num in "44" "-44" "44-" "4-4" "a4" "4a" ".4" "4.4" "-4.4" "09"
do
match=${num//[^[:digit:]]} # strip non-digits
match=${match#0*} # strip leading zeros
echo -en "$num\t$match\t"
case $num in
$match|-$match) echo "Integer";;
*) echo "Not integer";;
esac
done
This is what the test output looks like:
44 44 Integer -44 44 Integer 44- 44 Not integer 4-4 44 Not integer a4 4 Not integer 4a 4 Not integer .4 4 Not integer 4.4 44 Not integer -4.4 44 Not integer 09 9 Not integer
I had an issue with multiple slides. version 1.8.1

var i = (currentSlide ? currentSlide : 0) + 1;
var slidesToShow = slick.slickGetOption('slidesToShow');
var curPage = parseInt((i-1)/slidesToShow) + 1;
var lastPage = parseInt((slick.slideCount-1)/slidesToShow) + 1;
$('.your-selector').text(curPage);
$('.your-selector').text(lastPage);
});
Note curPage
and lastPage
is separate. I had to color them differently.
Based on top-voted answer
It is clear that most people who haven't used SQL Server Enterprise Manager don't understand the question (i.e. Justin Cave).
I came upon this post when I wanted to know the same thing.
Using SQL Server, when you are editing your data through the MS SQL Server GUI Tools, you can use a KEYBOARD SHORTCUT to insert a NULL rather than having just an EMPTY CELL, as they aren't the same thing. An empty cell can have a space in it, rather than being NULL, even if it is technically empty. The difference is when you intentionally WANT to put a NULL in a cell rather than a SPACE or to empty it and NOT using a SQL statement to do so.
So, the question really is, how do I put a NULL value in the cell INSTEAD of a space to empty the cell?
I think the answer is, that the way the Oracle Developer GUI works, is as Laniel indicated above, And THAT should be marked as the answer to this question.
Oracle Developer seems to default to NULL when you empty a cell the way the op is describing it.
Additionally, you can force Oracle Developer to change how your null cells look by changing the color of the background color to further demonstrate when a cell holds a null:
Tools->Preferences->Advanced->Display Null Using Background Color
or even the VALUE it shows when it's null:
Tools->Preferences->Advanced->Display Null Value As
Hope that helps in your transition.
If there is no hard requirement on the length of the truncated string, one can use this to truncate and prevent cutting the last word as well:
$text = "Knowledge is a natural right of every human being of which no one
has the right to deprive him or her under any pretext, except in a case where a
person does something which deprives him or her of that right. It is mere
stupidity to leave its benefits to certain individuals and teams who monopolize
these while the masses provide the facilities and pay the expenses for the
establishment of public sports.";
// we don't want new lines in our preview
$text_only_spaces = preg_replace('/\s+/', ' ', $text);
// truncates the text
$text_truncated = mb_substr($text_only_spaces, 0, mb_strpos($text_only_spaces, " ", 50));
// prevents last word truncation
$preview = trim(mb_substr($text_truncated, 0, mb_strrpos($text_truncated, " ")));
In this case, $preview
will be "Knowledge is a natural right of every human being"
.

It used to be a required part of a package (old, pre-3.3 "regular package", not newer 3.3+ "namespace package").
Python defines two types of packages, regular packages and namespace packages. Regular packages are traditional packages as they existed in Python 3.2 and earlier. A regular package is typically implemented as a directory containing an
__init__.py
file. When a regular package is imported, this__init__.py
file is implicitly executed, and the objects it defines are bound to names in the package’s namespace. The__init__.py
file can contain the same Python code that any other module can contain, and Python will add some additional attributes to the module when it is imported.
But just click the link, it contains an example, more information, and an explanation of namespace packages, the kind of packages without __init__.py
.
I created a new AutomapperProfile class. It extends Profile. We have over 100 projects in our solution. Many projects have an AutomapperProfile class, but this one was new to this existing project. However, I did find what I had to do to fix this issue for us. There is a Binding project. Within the Initialization there is this code:
var mappingConfig = new List<Action<IConfiguration>>();
// Initialize the Automapper Configuration for all Known Assemblies
mappingConfig.AddRange( new List<Action<IConfiguration>>
{
ConfigureProfilesInAssemblyOfType<Application.Administration.AutomapperProfile>,
//...
I had to add ConfigureProfilesInAssemblyOfType<MyNewNamespace.AutomapperProfile>
Note that ConfigureProfilesInAssemblyOfType looks like this:
private static void ConfigureProfilesInAssemblyOfType<T>( IConfiguration configuration )
{
var log = LogProvider.Get( typeof (AutomapperConfiguration) );
// The Automapper Profile Type
var automapperProfileType = typeof (Profile);
// The Assembly containing the type
var assembly = typeof (T).Assembly;
log.Debug( "Scanning " + assembly.FullName );
// Configure any Profile classes found in the assembly containing the type.
assembly.GetTypes()
.Where( automapperProfileType.IsAssignableFrom ).ToList()
.ForEach( x =>
{
log.Debug( "Adding Profile '" + x.FullName + "'" );
configuration.AddProfile( Activator.CreateInstance( x ) as Profile );
} );
}

I had the same issue. Tried all the above and found I also had to delete everything inside {PROJECT_ROOT}\bin\Release\netcoreapp2.2 and {PROJECT_ROOT}\obj\Release\netcoreapp2.2 for my project.

If you use anaconda, you can just create a new environment with the specified version. In case you don't want to keep the existing version 3.7, you can just uninstall it and install it from here.
You need to git add my_project
to stage your new folder. Then git add my_project/*
to stage its contents. Then commit what you've staged using git commit
and finally push your changes back to the source using git push origin master
(I'm assuming you wish to push to the master branch).
You would do:
char c = str[1];
Or even:
char c = "Hello"[1];
edit: updated to find the "E".
It's 2018 now.And I just got stuck on this problem when I must send a request that exceeds the max_input_vars

param. because I only tried to restart apache2
service, but not php fpm
/etc/php/7.0/fpm/php.ini
and set number as you wish max_input_vars = 4000
sudo service php7.0-fpm restart

In [9]: plot([23, 456, 676, 89, 906, 34, 2345])
Out[9]: [<matplotlib.lines.Line2D at 0x6112f90>]
In [10]: yscale('log')
In [11]: grid(b=True, which='major', color='b', linestyle='-')
In [12]: grid(b=True, which='minor', color='r', linestyle='--')
The gotcha with minor grids is that you have to have minor tick marks turned on too. In the above code this is done by yscale('log')
, but it can also be done with plt.minorticks_on()
.
Here's a more portable version (just for fun, it is not necessary in your case):
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from subprocess import Popen, PIPE, STDOUT
try:
from subprocess import DEVNULL # py3k
except ImportError:
import os
DEVNULL = open(os.devnull, 'wb')
text = u"René Descartes"
p = Popen(['espeak', '-b', '1'], stdin=PIPE, stdout=DEVNULL, stderr=STDOUT)
p.communicate(text.encode('utf-8'))
assert p.returncode == 0 # use appropriate for your program error handling here
The file .so is not a UNIX file extension for shared library.
It just happens to be a common one.
Check line 3b at ArnaudRecipes sharedlib page
Basically .dylib is the mac file extension used to indicate a shared lib.
Under Bash (at least), this can be done automatically with tab completion:
make
spacetabtab
Yes, this is possible and I would like to provide a slight alternative to Rajeev's answer that does not pass a php-generated datetime formatted string to the query.
The important distinction about how to declare the values to be SET in the UPDATE query is that they must not be quoted as literal strings.
To prevent CodeIgniter from doing this "favor" automatically, use the set()
method with a third parameter of false
.
$userId = 444;
$this->db->set('Last', 'Current', false);
$this->db->set('Current', 'NOW()', false);
$this->db->where('Id', $userId);
// return $this->db->get_compiled_update('Login'); // uncomment to see the rendered query
$this->db->update('Login');
return $this->db->affected_rows(); // this is expected to return the integer: 1
The generated query (depending on your database adapter) would be like this:
UPDATE `Login` SET Last = Current, Current = NOW() WHERE `Id` = 444
Demonstrated proof that the query works: https://www.db-fiddle.com/f/vcc6PfMcYhDD87wZE5gBtw/0
In this case, Last
and Current
ARE MySQL Keywords, but they are not Reserved Keywords, so they don't need to be backtick-wrapped.
If your precise query needs to have properly quoted identifiers (table/column names), then there is always protectIdentifiers().
The ZT Process Executor library is an alternative to Apache Commons Exec. It has functionality to run commands, capturing their output, setting timeouts, etc.
I have not used it yet, but it looks reasonably well-documented.
An example from the documentation: Executing a command, pumping the stderr to a logger, returning the output as UTF8 string.
String output = new ProcessExecutor().command("java", "-version")
.redirectError(Slf4jStream.of(getClass()).asInfo())
.readOutput(true).execute()
.outputUTF8();
Its documentation lists the following advantages over Commons Exec:
If you’re looking for a self-contained clone or backup that includes all remote branches and commit logs, use:
git clone http://[email protected]
git pull --all
The accepted answer of git branch -a
only shows the remote branches. If you attempt to checkout
the branches you'll be unable to unless you still have network access to the origin server.
Credit: Gabe Kopley's for suggesting using git pull --all
.
Note:
Of course, if you no longer have network access to the remote/origin
server, remote/origin branches
will not have any updates reflected in them. Their revisions will reflect commits from the date and time you performed the 2 commands above.
To checkout ALL your clone branches to local branches with one command, use one of the bash commands below:
$ for i in $(git branch -a |grep 'remotes' | awk -F/ '{print $3}' \
| grep -v 'HEAD ->');do git checkout -b $i --track origin/$i; done
OR
If your repo has nested branches then this command will take that into account:
for i in $(git branch -a |grep 'remotes' |grep -v 'HEAD ->');do \
basename ${i##\./} | xargs -I {} git checkout -b {} --track origin/{}; done
The above commands will checkout
a local branch into your local git repository, named the same as the remote/origin/<branchname>
and set it to --track
changes from the remote branch on the remote/origin
server should you regain network access to your origin repo server once more and perform a git pull
command in the usual way.
There is a (somewhat) related question on StackOverflow:
Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeeze
d or sliced into a 2D array.
More generally, the reason for the Exception
TypeError: Invalid dimensions for image data
is shown here: matplotlib.pyplot.imshow()
needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!
You can easily check this with (these checks are done by imshow
, this function is only meant to give a more specific message in case it's not a valid input):
from __future__ import print_function
import numpy as np
def valid_imshow_data(data):
data = np.asarray(data)
if data.ndim == 2:
return True
elif data.ndim == 3:
if 3 <= data.shape[2] <= 4:
return True
else:
print('The "data" has 3 dimensions but the last dimension '
'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
''.format(data.shape[2]))
return False
else:
print('To visualize an image the data must be 2 dimensional or '
'3 dimensional, not "{}".'
''.format(data.ndim))
return False
In your case:
>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False
The np.asarray
is what is done internally by matplotlib.pyplot.imshow
so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list
) it's necessary.
In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()
import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0) # or axis=1
plt.imshow(a)
plt.show()
or just use something that accepts 1D arrays like plot
:
a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()
All the above method will work. but to use the var as env variable inside your code you need to export the var first.
script{
sh " 'shell command here' > command"
command_var = readFile('command').trim()
sh "export command_var=$command_var"
}
replace the shell command with the command of your choice. Now if you are using python code you can just specify os.getenv("command_var") that will return the output of the shell command executed previously.
<form class="upload-form">
<input class="upload-file" data-max-size="2048" type="file" >
<input type=submit>
</form>
<script>
$(function(){
var fileInput = $('.upload-file');
var maxSize = fileInput.data('max-size');
$('.upload-form').submit(function(e){
if(fileInput.get(0).files.length){
var fileSize = fileInput.get(0).files[0].size; // in bytes
if(fileSize>maxSize){
alert('file size is more then' + maxSize + ' bytes');
return false;
}else{
alert('file size is correct- '+fileSize+' bytes');
}
}else{
alert('choose file, please');
return false;
}
});
});
</script>
Since you actually want a different array which is arr
where arr < 255
, and 255
otherwise, this can be done simply:
result = np.minimum(arr, 255)
More generally, for a lower and/or upper bound:
result = np.clip(arr, 0, 255)
If you just want to access the values over 255, or something more complicated, @mtitan8's answer is more general, but np.clip
and np.minimum
(or np.maximum
) are nicer and much faster for your case:
In [292]: timeit np.minimum(a, 255)
100000 loops, best of 3: 19.6 µs per loop
In [293]: %%timeit
.....: c = np.copy(a)
.....: c[a>255] = 255
.....:
10000 loops, best of 3: 86.6 µs per loop
If you want to do it in-place (i.e., modify arr
instead of creating result
) you can use the out
parameter of np.minimum
:
np.minimum(arr, 255, out=arr)
or
np.clip(arr, 0, 255, arr)
(the out=
name is optional since the arguments in the same order as the function's definition.)
For in-place modification, the boolean indexing speeds up a lot (without having to make and then modify the copy separately), but is still not as fast as minimum
:
In [328]: %%timeit
.....: a = np.random.randint(0, 300, (100,100))
.....: np.minimum(a, 255, a)
.....:
100000 loops, best of 3: 303 µs per loop
In [329]: %%timeit
.....: a = np.random.randint(0, 300, (100,100))
.....: a[a>255] = 255
.....:
100000 loops, best of 3: 356 µs per loop
For comparison, if you wanted to restrict your values with a minimum as well as a maximum, without clip
you would have to do this twice, with something like
np.minimum(a, 255, a)
np.maximum(a, 0, a)
or,
a[a>255] = 255
a[a<0] = 0
You need to use parentheses: myList.insert([1, 2, 3])
. When you leave out the parentheses, python thinks you are trying to access myList.insert
at position 1, 2, 3
, because that's what brackets are used for when they are right next to a variable.
The quickest and easiest way to fix this is to do a find and replace on your date seperator, with the same separator. For example in this case Find "-" and Replace with "-", not sure why this works but you will find all dates are right-aligned as they should be after doing this.
Be advised that if you're using nodejs there's (at the time of writing) a dependency on libssl 1.0.* - so installing an alternative SSL library will break your nodejs installation.
An alternative solution to installing a different SSL library is that posted in this answer here: https://stackoverflow.com/a/59927568/13564342 to instead install libcurl4-gnutls-dev
sudo apt install libcurl4-gnutls-dev
I have an improvement over the sedeasy function, which WILL break with special characters like tab.
function sedeasy_improved {
sed -i "s/$(
echo "$1" | sed -e 's/\([[\/.*]\|\]\)/\\&/g'
| sed -e 's:\t:\\t:g'
)/$(
echo "$2" | sed -e 's/[\/&]/\\&/g'
| sed -e 's:\t:\\t:g'
)/g" "$3"
}
So, whats different? $1
and $2
wrapped in quotes to avoid shell expansions and preserve tabs or double spaces.
Additional piping | sed -e 's:\t:\\t:g'
(I like :
as token) which transforms a tab in \t
.

Hi I know this was asked a while ago but I've just figured this out and it might help someone else. Not sure if this is exactly what you're looking for but this is how I call a stored proc and view the output using SQL Developer.
In SQL Developer when viewing the proc, right click and choose 'Run' or select Ctrl+F11 to bring up the Run PL/SQL window. This creates a template with the input and output params which you need to modify. My proc returns a sys_refcursor. The tricky part for me was declaring a row type that is exactly equivalent to the select stmt / sys_refcursor being returned by the proc:
DECLARE
P_CAE_SEC_ID_N NUMBER;
P_FM_SEC_CODE_C VARCHAR2(200);
P_PAGE_INDEX NUMBER;
P_PAGE_SIZE NUMBER;
v_Return sys_refcursor;
type t_row is record (CAE_SEC_ID NUMBER,FM_SEC_CODE VARCHAR2(7),rownum number, v_total_count number);
v_rec t_row;
BEGIN
P_CAE_SEC_ID_N := NULL;
P_FM_SEC_CODE_C := NULL;
P_PAGE_INDEX := 0;
P_PAGE_SIZE := 25;
CAE_FOF_SECURITY_PKG.GET_LIST_FOF_SECURITY(
P_CAE_SEC_ID_N => P_CAE_SEC_ID_N,
P_FM_SEC_CODE_C => P_FM_SEC_CODE_C,
P_PAGE_INDEX => P_PAGE_INDEX,
P_PAGE_SIZE => P_PAGE_SIZE,
P_FOF_SEC_REFCUR => v_Return
);
-- Modify the code to output the variable
-- DBMS_OUTPUT.PUT_LINE('P_FOF_SEC_REFCUR = ');
loop
fetch v_Return into v_rec;
exit when v_Return%notfound;
DBMS_OUTPUT.PUT_LINE('sec_id = ' || v_rec.CAE_SEC_ID || 'sec code = ' ||v_rec.FM_SEC_CODE);
end loop;
END;
Perhaps table is what you are after?
dummyData = rep(c(1,2, 2, 2), 25)
table(dummyData)
# dummyData
# 1 2
# 25 75
## or another presentation of the same data
as.data.frame(table(dummyData))
# dummyData Freq
# 1 1 25
# 2 2 75
Although there are already excellent answers are provided by users such as encouraging use of GSON etc. I would like to suggest use of org.json. It includes most of GSON functionalities. It also allows you to pass json string as an argument to it's JSONObject and it will take care of rest e.g:
JSONObject json = new JSONObject("some random json string");
This functionality make it my personal favorite.
You need not specify receiver. You can use adb instead.
adb shell am broadcast -a com.whereismywifeserver.intent.TEST
--es sms_body "test from adb"
For more arguments such as integer extras, see the documentation.

Simply import the Android library project as a module and in Build.gradle.
Apply plugin: 'com.android.library'
After that, follow these steps:
The design of HTTP means that making a POST with data will return a page. The original designers probably intended for that to be a "result" page of your POST.
It is normal for a PHP application to POST back to the same page as it can not only process the POST request, but it can generate an updated page based on the original GET but with the new information from the POST. However, there's nothing stopping your server code from providing completely different output. Alternatively, you could POST to an entirely different page.
If you don't want the output, one method that I've seen before AJAX took off was for the server to return a HTTP response code of (I think) 250. This is called "No Content" and this should make the browser ignore the data.
Of course, the third method is to make an AJAX call with your submitted data, instead.
I use the readonly
attribute instead of disabled
attribute - as this will still submit the value when the field is readonly.
Note: Any presence of the readonly attribute will make the field readonly
even if set to false, so hence why I branch the editor for code like below.
@if (disabled)
{
@Html.EditorFor(model => contact.EmailAddress, new { htmlAttributes = new { @class = "form-control", @readonly = "" } })
}
else
{
@Html.EditorFor(model => contact.EmailAddress, new { htmlAttributes = new { @class = "form-control" } })
}
Converted from comment for the sake of visitor's convenience
It's not clear from this message what the correct syntax is. It is:
ALTER SEQUENCE product_id_seq RESTART WITH 1453;
The precision of float is 7 digits. If you want to keep the whole lot, you need to use the double type that keeps 15-16 digits. Regarding formatting, look at a post about formatting doubles. And you need to worry about decimal separators in C#.
Here's another using the zip
function.
>>> a = [3, 7, 19]
>>> zip(range(len(a)), a)
[(0, 3), (1, 7), (2, 19)]
The most likely explanations for that error are:
CreateProcess
requires you to provide an executable file. If you wish to be able to open any file with its associated application then you need ShellExecute
rather than CreateProcess
.Reading down to the bottom of the code, I can see that the problem is number 1.

Throwable
is super class of Exception
as well as Error
. In normal cases we should always catch sub-classes of Exception
, so that the root cause doesn't get lost.
Only special cases where you see possibility of things going wrong which is not in control of your Java code, you should catch Error
or Throwable
.
I remember catching Throwable to flag that a native library is not loaded.
Simplifying a bit, you can imagine map()
doing something like this:
def mymap(func, lst):
result = []
for e in lst:
result.append(func(e))
return result
As you can see, it takes a function and a list, and returns a new list with the result of applying the function to each of the elements in the input list. I said "simplifying a bit" because in reality map()
can process more than one iterable:
If additional iterable arguments are passed, function must take that many arguments and is applied to the items from all iterables in parallel. If one iterable is shorter than another it is assumed to be extended with None items.
For the second part in the question: What role does this play in making a Cartesian product? well, map()
could be used for generating the cartesian product of a list like this:
lst = [1, 2, 3, 4, 5]
from operator import add
reduce(add, map(lambda i: map(lambda j: (i, j), lst), lst))
... But to tell the truth, using product()
is a much simpler and natural way to solve the problem:
from itertools import product
list(product(lst, lst))
Either way, the result is the cartesian product of lst
as defined above:
[(1, 1), (1, 2), (1, 3), (1, 4), (1, 5),
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5),
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5),
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5),
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5)]
accuracy_score is a classification metric, you cannot use it for a regression problem.

Apple's new system font is not publicly exposed. Apple has started abstracting system font names:
The motivation for this abstraction is so the operating system can make better choices on which face to use at a given weight. Apple is also working on font features, such as selectable “6" and “9" glyphs or non-monospaced numbers. It’s my guess that they’d like to bring these features to the web, as well.
Safari and Firefox use SF for -apple-system
; Chrome recognizes BlinkMacSystemFont
:
body {
font-family: -apple-system, BlinkMacSystemFont, sans-serif;
}
There are also other variations:
font-family: -apple-system-body
font-family: -apple-system-headline
font-family: -apple-system-subheadline
font-family: -apple-system-caption1
font-family: -apple-system-caption2
font-family: -apple-system-footnote
font-family: -apple-system-short-body
font-family: -apple-system-short-headline
font-family: -apple-system-short-subheadline
font-family: -apple-system-short-caption1
font-family: -apple-system-short-footnote
font-family: -apple-system-tall-body
You can demo these at the following fiddle; most are not supported yet: http://jsfiddle.net/v94gw9nx/
I got my info from Craig Hockenberry's article which has a lot of great info about using the font: http://furbo.org/2015/07/09/i-left-my-system-fonts-in-san-francisco/
Also, some great info on the Surfin' Safari blog about using abstracted system fonts: https://www.webkit.org/blog/3709/using-the-system-font-in-web-content/
And apparently Apple is working with the W3C to standardize using a generic "system" font name in CSS. https://lists.w3.org/Archives/Public/www-style/2015Jul/0169.html

You ask specifically about map()
, filter()
and reduce()
, but I assume you want to know about functional programming in general. Having tested this myself on the problem of computing distances between all points within a set of points, functional programming (using the starmap
function from the built-in itertools
module) turned out to be slightly slower than for-loops (taking 1.25 times as long, in fact). Here is the sample code I used:
import itertools, time, math, random
class Point:
def __init__(self,x,y):
self.x, self.y = x, y
point_set = (Point(0, 0), Point(0, 1), Point(0, 2), Point(0, 3))
n_points = 100
pick_val = lambda : 10 * random.random() - 5
large_set = [Point(pick_val(), pick_val()) for _ in range(n_points)]
# the distance function
f_dist = lambda x0, x1, y0, y1: math.sqrt((x0 - x1) ** 2 + (y0 - y1) ** 2)
# go through each point, get its distance from all remaining points
f_pos = lambda p1, p2: (p1.x, p2.x, p1.y, p2.y)
extract_dists = lambda x: itertools.starmap(f_dist,
itertools.starmap(f_pos,
itertools.combinations(x, 2)))
print('Distances:', list(extract_dists(point_set)))
t0_f = time.time()
list(extract_dists(large_set))
dt_f = time.time() - t0_f
Is the functional version faster than the procedural version?
def extract_dists_procedural(pts):
n_pts = len(pts)
l = []
for k_p1 in range(n_pts - 1):
for k_p2 in range(k_p1, n_pts):
l.append((pts[k_p1].x - pts[k_p2].x) ** 2 +
(pts[k_p1].y - pts[k_p2].y) ** 2)
return l
t0_p = time.time()
list(extract_dists_procedural(large_set))
# using list() on the assumption that
# it eats up as much time as in the functional version
dt_p = time.time() - t0_p
f_vs_p = dt_p / dt_f
if f_vs_p >= 1.0:
print('Time benefit of functional progamming:', f_vs_p,
'times as fast for', n_points, 'points')
else:
print('Time penalty of functional programming:', 1 / f_vs_p,
'times as slow for', n_points, 'points')
Yes. For that ensure that you declare the worksheet
For example
Previous Code
Sub Sample()
Dim ws As Worksheet
Set ws = Sheets("Sheet3")
Debug.Print ws.Cells(23, 4).Value
End Sub
New Code
Sub Sample()
Dim ws As Worksheet
Set ws = Sheets("Sheet4")
Debug.Print ws.Cells(23, 4).Value
End Sub
Try this:
myrecyclerview.setLayoutManager(

myrecyclerview.setAdapter(recyclerAdapter);
only in case you got a recycler view with some fragments on it.
If ALTER COLUMN doesn't work.
It is not unusual for alter column to fail because it cannot make the transformation you desire. In this case, the solution is to create a dummy table TableName_tmp, copy the data over with your specialized transformation in the bulk Insert command, drop the original table, and rename the tmp table to the original table's name. You'll have to drop and recreate the Foreign key constraints and, for performance, you'll probably want to create keys after filling the tmp table.
Sound like a lot of work? Actually, it isn't.
If you are using SQL Server, you can make the SQL Server Management Studio do the work for you!
enum
s in C don't really work the way you're expecting them to. You can think of them kind of like glorified constants (with a few additional benefits relating to being a collection of such constants), and the text you've written in for "Sunday" really gets resolved to a number during compilation, the text is ultimately discarded.
In short: to do what you really want you'll need to keep an array of the strings or create a function to map from the enum's value to the text you'd like to print.
if you need the batch file to schedule the backup, the SQL management tools have scheduled tasks built in...
I have created a working CodePen example to demonstrate how you might accomplish your goals.
I added ng-click
to the <form>
and removed the logic from your button:
<form name="addRelation" data-ng-click="save(model)">
...
<input class="btn" type="submit" value="SAVE" />
Here's the updated template:
<section ng-app="app" ng-controller="MainCtrl">
<form class="well" name="addRelation" data-ng-click="save(model)">
<label>First Name</label>
<input type="text" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/><br/>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.FirstName.$invalid">First Name is required</span><br/>
<label>Last Name</label>
<input type="text" placeholder="Last Name" data-ng-model="model.lastName" id="LastName" name="LastName" required/><br/>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.LastName.$invalid">Last Name is required</span><br/>
<label>Email</label>
<input type="email" placeholder="Email" data-ng-model="model.email" id="Email" name="Email" required/><br/>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.required">Email address is required</span>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.email">Email address is not valid</span><br/>
<input class="btn" type="submit" value="SAVE" />
</form>
</section>
and controller code:
app.controller('MainCtrl', function($scope) {
$scope.save = function(model) {
$scope.addRelation.submitted = true;
if($scope.addRelation.$valid) {
// submit to db
console.log(model);
} else {
console.log('Errors in form data');
}
};
});
I hope this helps.
1) Go to (Open) Command Prompt (Press Window + R then type cmd Run this).
2) Run following commands
For all listening ports
Apply port filter
Finally with the PID we can run the following command to kill the process
3) Copy PID from result set
Ex: taskkill /F /PID 189
Done !!! you can start your service now.
An easier way to get the machine epsilon for a given float type is to use np.finfo()
:
print(np.finfo(float).eps)
# 2.22044604925e-16
print(np.finfo(np.float32).eps)
# 1.19209e-07
Obtaining UTC date
gmdate("Y-m-d H:i:s");
Obtaining UTC timestamp
time();
The result will not be different even you have date_default_timezone_set
on your code.
very old post. but i'll just leave this here:
/* converts a number with byte unit (B / K / M / G) into an integer */
function unitToInt($s)
{
return (int)preg_replace_callback('/(\-?\d+)(.?)/', function ($m) {
return $m[1] * pow(1024, strpos('BKMG', $m[2]));
}, strtoupper($s));
}
$mem_limit = unitToInt(ini_get('memory_limit'));
It seems like it exists a bug in jQuery reported here : http://bugs.jquery.com/ticket/13183 that breaks the Fancybox script.
Also check https://github.com/fancyapps/fancyBox/issues/485 for further reference.
As a workaround, rollback to jQuery v1.8.3 while either the jQuery bug is fixed or Fancybox is patched.
UPDATE (Jan 16, 2013): Fancybox v2.1.4 has been released and now it works fine with jQuery v1.9.0.
For fancybox v1.3.4- you still need to rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.
UPDATE (Jan 17, 2013): Workaround for users of Fancybox v1.3.4 :
Patch the fancybox js file to make it work with jQuery v1.9.0 as follow :
Find around the line 29 where it says :
isIE6 = $.browser.msie && $.browser.version < 7 && !window.XMLHttpRequest,
and replace it by (EDITED March 19, 2013: more accurate filter):
isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,
UPDATE (March 19, 2013): Also replace $.browser.msie
by navigator.userAgent.match(/msie [6]/i)
around line 615 (and/or replace all $.browser.msie
instances, if any), thanks joofow
... that's it!
Or download the already patched version from HERE (UPDATED March 19, 2013 ... thanks fairylee for pointing out the extra closing bracket)
NOTE: this is an unofficial patch and is unsupported by Fancybox's author, however it works as is. You may use it at your own risk ;)
Optionally, you may rather rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.
For people from Brazil
There is a security software called Warsaw (used for home banking) that must be uninstalled! After you can install it back again.
After thousand times trying, installing, uninstalling, cleanning-up the regedit that finally solved the problem.
It should be fixed on server side. Your server should return this headers for this file types:
Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"
Ned Rockson basically answers this question. However there is a fatal flaw within his solution. When the targeted element is closer to the bottom of the page than the viewport-height, the function doesn't reach its exit statement and traps the user on the bottom of the page. This is simply solved by limiting the iteration count.
var smoothScroll = function(elementId) {
var MIN_PIXELS_PER_STEP = 16;
var MAX_SCROLL_STEPS = 30;
var target = document.getElementById(elementId);
var scrollContainer = target;
do {
scrollContainer = scrollContainer.parentNode;
if (!scrollContainer) return;
scrollContainer.scrollTop += 1;
} while (scrollContainer.scrollTop == 0);
var targetY = 0;
do {
if (target == scrollContainer) break;
targetY += target.offsetTop;
} while (target = target.offsetParent);
var pixelsPerStep = Math.max(MIN_PIXELS_PER_STEP,
(targetY - scrollContainer.scrollTop) / MAX_SCROLL_STEPS);
var iterations = 0;
var stepFunc = function() {
if(iterations > MAX_SCROLL_STEPS){
return;
}
scrollContainer.scrollTop =
Math.min(targetY, pixelsPerStep + scrollContainer.scrollTop);
if (scrollContainer.scrollTop >= targetY) {
return;
}
window.requestAnimationFrame(stepFunc);
};
window.requestAnimationFrame(stepFunc);
}
In Opera, try:

print_win.document.close(); // This bit is important
print_win.print();
print_win.close();
code that works, but output is:

30
40
50
so:
List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
for (Integer number : myCoords) {
System.out.println(number);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {

The power in dBm is the 10 times the logarithm of the ratio of actual Power/1 milliWatt.
dBm stands for "decibel milliwatts". It is a convenient way to measure power. The exact formula is
P(dBm) = 10 · log10( P(W) / 1mW )
where
P(dBm) = Power expressed in dBm P(W) = the absolute power measured in Watts mW = milliWatts log10 = log to base 10
From this formula, the power in dBm of 1 Watt is 30 dBm. Because the calculation is logarithmic, every increase of 3dBm is approximately equivalent to doubling the actual power of a signal.
There is a conversion calculator and a comparison table here. There is also a comparison table on the Wikipedia english page, but the value it gives for mobile networks is a bit off.
Your actual question was "does the - sign count?"
The answer is yes, it does.
-85 dBm is less powerful (smaller) than -60 dBm. To understand this, you need to look at negative numbers. Alternatively, think about your bank account. If you owe the bank 85 dollars/rands/euros/rupees (-85), you're poorer than if you only owe them 65 (-65), i.e. -85 is smaller than -65. Also, in temperature measurements, -85 is colder than -65 degrees.
Signal strengths for mobile networks are always negative dBm values, because the transmitted network is not strong enough to give positive dBm values.
How will this affect your location finding? I have no idea, because I don't know what technology you are using to estimate the location. The values you quoted correspond roughly to a 5 bar network in GSM, UMTS or LTE, so you shouldn't have be having any problems due to network strength.
In Python 3, I was able to do this:
import os
dir = "/path/to/files/"
#List all files immediately under this folder:
print ( next( os.walk(dir) )[2] )
#List all folders immediately under this folder:
print ( next( os.walk(dir) )[1] )
I was looking for something like the rails approach used in ActiveRecord to_json and implemented something similar using this Mixin after being unsatisfied with other suggestions. It handles nested models, and including or excluding attributes of the top level or nested models.
class Serializer(object):
def serialize(self, include={}, exclude=[], only=[]):
serialized = {}
for key in inspect(self).attrs.keys():
to_be_serialized = True
value = getattr(self, key)
if key in exclude or (only and key not in only):
to_be_serialized = False
elif isinstance(value, BaseQuery):
to_be_serialized = False
if key in include:
to_be_serialized = True
nested_params = include.get(key, {})
value = [i.serialize(**nested_params) for i in value]
if to_be_serialized:
serialized[key] = value
return serialized
Then, to get the BaseQuery serializable I extended BaseQuery
class SerializableBaseQuery(BaseQuery):
def serialize(self, include={}, exclude=[], only=[]):
return [m.serialize(include, exclude, only) for m in self]
For the following models
class ContactInfo(db.Model, Serializer):
id = db.Column(db.Integer, primary_key=True)
user_id = db.Column(db.Integer, db.ForeignKey('user.id'))
full_name = db.Column(db.String())
source = db.Column(db.String())
source_id = db.Column(db.String())
email_addresses = db.relationship('EmailAddress', backref='contact_info', lazy='dynamic')
phone_numbers = db.relationship('PhoneNumber', backref='contact_info', lazy='dynamic')
class EmailAddress(db.Model, Serializer):
id = db.Column(db.Integer, primary_key=True)
email_address = db.Column(db.String())
type = db.Column(db.String())
contact_info_id = db.Column(db.Integer, db.ForeignKey('contact_info.id'))
class PhoneNumber(db.Model, Serializer):
id = db.Column(db.Integer, primary_key=True)
phone_number = db.Column(db.String())
type = db.Column(db.String())
contact_info_id = db.Column(db.Integer, db.ForeignKey('contact_info.id'))
phone_numbers = db.relationship('Invite', backref='phone_number', lazy='dynamic')
You could do something like
@app.route("/contact/search", methods=['GET'])
def contact_search():
contact_name = request.args.get("name")
matching_contacts = ContactInfo.query.filter(ContactInfo.full_name.like("%{}%".format(contact_name)))
serialized_contact_info = matching_contacts.serialize(
include={
"phone_numbers" : {
"exclude" : ["contact_info", "contact_info_id"]
},
"email_addresses" : {
"exclude" : ["contact_info", "contact_info_id"]
}
}
)
return jsonify(serialized_contact_info)
You can start and stop and query services using the SC command. As for innosetup i'm not sure.
Have you tried using the concat() function?
ON tableTwo.query = concat('category_id=',tableOne.category_id)
A little bit modified answer of @cope360:
create table test (a int, b int, c int, constraint pk_test primary key(c, a, b));
select i.relname as index_name,
ix.indisunique as is_unique,
a.attname as column_name,
from pg_class c
inner join pg_index ix on c.oid=ix.indrelid
inner join pg_class i on ix.indexrelid=i.oid
inner join pg_attribute a on a.attrelid=c.oid and a.attnum=any(ix.indkey)
where c.oid='public.test'::regclass::oid
order by array_position(ix.indkey, a.attnum) asc;
This will show the index columns in correct order:
index_name is_unique column_name
pk_test true c
pk_test true a
pk_test true b
we could use a simple if else:
item_list=[]
if len(item_list) == 0:
print("list is empty")
else:
print("list is not empty")
!=
, despite being non-ANSI, is more in the true spirit of SQL as a readable language. It screams not equal.
<>
says it's to me (less than, greater than) which is just weird. I know the intention is that it's either less than or greater than hence not equal, but that's a really complicated way of saying something really simple.
I've just had to take some long SQL queries and place them lovingly into an XML file for a whole bunch of stupid reasons I won't go into.
Suffice to say XML is not down with <>
at all and I had to change them to !=
and check myself before I riggedy wrecked myself.
You could use "let" too like this :
[ ~]$ var=1
[ ~]$ let $var && echo "It's a number" || echo "It's not a number"
It\'s a number
[ ~]$ var=01
[ ~]$ let $var && echo "It's a number" || echo "It's not a number"
It\'s a number
[ ~]$ var=toto
[ ~]$ let $var && echo "It's a number" || echo "It's not a number"
It\'s not a number
[ ~]$
But I prefer use the "=~" Bash 3+ operator like some answers in this thread.
This is simple way to Display Div using:-
$("#musicinfo").show(); //or
$("#musicinfo").css({'display':'block'}); //or
$("#musicinfo").toggle("slow"); //or
$("#musicinfo").fadeToggle(); //or
As stated above, many languages are available for developing in Android. Java, C, Scala, C++, several scripting languages etc. Thanks to Mono you are also able to develop using C# and the .Net framework. Here you have some speedcomparisions: http://www.youtube.com/watch?v=It8xPqkKxis
Type-check with the -is operator returns false for any null value. In most cases, if not all, $value -is [System.Object] will be true for any possible non-null value. (In all cases, it will be false for any null-value.)
My value is nothing if not an object.

I ended up here after struggling for a while, but actually what I was missing was just:
If a #include file or one of its dependencies cannot be found, you can also click on the red squiggles under the include statements to view suggestions for how to update your configuration.

Couldn't you do an outer join, only selecting the items from the first list if the group is empty? Something like:
Dim result = (From a In list1
Group Join b In list2
On a.Value Equals b.Value
Into grp = Group
Where Not grp.Any
Select a)
I'm unsure whether this would work in any sort of efficient way with the Entity framework.
An alternative that may fit in some situations is to assign the result of a command to a variable:
$ DUMMY=$( grep root /etc/passwd 2>&1 )
$ echo $?
0
$ DUMMY=$( grep r00t /etc/passwd 2>&1 )
$ echo $?
1
Since Bash and other POSIX commandline interpreters does not consider variable assignments as a command, the present command's return code is respected.
Note: assignement with the typeset
or declare
keyword is considered as a command, so the evaluated return code in case is the assignement itself and not the command executed in the sub-shell:
$ declare DUMMY=$( grep r00t /etc/passwd 2>&1 )
$ echo $?
0
The default data directory for MongoDB is /data/db
.
This can be overridden by a dbpath
option specified on the command line or in a configuration file.
If you install MongoDB via a package manager such as Homebrew or MacPorts these installs typically create a default data directory other than /data/db and set the dbpath in a configuration file.
If a dbpath was provided to mongod
on startup you can check the value in the mongo
shell:
db.serverCmdLineOpts()
You would see a value like:
"parsed" : {
"dbpath" : "/usr/local/data"
},
Another Python PCA using numpy. The same idea as @doug but that one didn't run.
from numpy import array, dot, mean, std, empty, argsort
from numpy.linalg import eigh, solve
from numpy.random import randn
from matplotlib.pyplot import subplots, show
def cov(X):
"""
Covariance matrix
note: specifically for mean-centered data
note: numpy's `cov` uses N-1 as normalization
"""
return dot(X.T, X) / X.shape[0]
# N = data.shape[1]
# C = empty((N, N))
# for j in range(N):
# C[j, j] = mean(data[:, j] * data[:, j])
# for k in range(j + 1, N):
# C[j, k] = C[k, j] = mean(data[:, j] * data[:, k])
# return C
def pca(data, pc_count = None):
"""

note: this mean-centers and auto-scales the data (in-place)
"""
data -= mean(data, 0)
data /= std(data, 0)
C = cov(data)
E, V = eigh(C)
key = argsort(E)[::-1][:pc_count]
E, V = E[key], V[:, key]
U = dot(data, V) # used to be dot(V.T, data.T).T
return U, E, V
""" test data """
data = array([randn(8) for k in range(150)])
data[:50, 2:4] += 5
data[50:, 2:5] += 5
""" visualize """
trans = pca(data, 3)[0]
fig, (ax1, ax2) = subplots(1, 2)
ax1.scatter(data[:50, 0], data[:50, 1], c = 'r')
ax1.scatter(data[50:, 0], data[50:, 1], c = 'b')
ax2.scatter(trans[:50, 0], trans[:50, 1], c = 'r')
ax2.scatter(trans[50:, 0], trans[50:, 1], c = 'b')
show()
Which yields the same thing as the much shorter
from sklearn.decomposition import PCA
def pca2(data, pc_count = None):
return PCA(n_components = 4).fit_transform(data)
As I understand it, using eigenvalues (first way) is better for high-dimensional data and fewer samples, whereas using Singular value decomposition is better if you have more samples than dimensions.
You can use rails dbconsole
to view the database that your rails application is using. It's alternative answer rails db
. Both commands will direct you the command line interface and will allow you to use that database query syntax.
You don't need error handling in order to accomplish this. All you have to do is iterate over all of the Worksheets and check if the specified name exists:
For i = 1 To Worksheets.Count
If Worksheets(i).Name = "MySheet" Then
exists = True
End If
Next i
If Not exists Then
Worksheets.Add.Name = "MySheet"
End If
I think you can try this:
<a th:href="${'/category/edit/' + {category.id}}">view</a>
Or if you have "idCategory" this:
<a th:href="${'/category/edit/' + {category.idCategory}}">view</a>
Another way is:
f = open("|ls")
foo = f.read()
Note that's the "pipe" character before "ls" in open. This can also be used to feed data into the programs standard input as well as reading its standard output.
In this particular case, an even simpler fix would be to just get rid of the "+" all together because AGE is a string literal and what comes before and after are also string literals. You could write line 3 as:
str += "Do you feel " AGE " years old?";
This is because most C/C++ compilers will concatenate string literals automatically. The above is equivalent to:
str += "Do you feel " "42" " years old?";
which the compiler will convert to:
str += "Do you feel 42 years old?";
If your branch is behind by master then do:
git checkout master (you are switching your branch to master)
git pull
git checkout yourBranch (switch back to your branch)
git merge master
After merging it, check if there is a conflict or not.
If there is NO CONFLICT then:
git push
If there is a conflict then fix your file(s), then:
git add yourFile(s)
git commit -m 'updating my branch'
git push
You can also use Guava and do something like this:
// This method returns enum for a given string if it exists, otherwise it returns default enum.
private MyEnum getMyEnum(String enumName) {
// It is better to return default instance of enum instead of null
return hasMyEnum(enumName) ? MyEnum.valueOf(enumName) : MyEnum.DEFAULT;
}
// This method checks that enum for a given string exists.
private boolean hasMyEnum(String enumName) {
return Iterables.any(Arrays.asList(MyEnum.values()), new Predicate<MyEnum>() {
public boolean apply(MyEnum myEnum) {
return myEnum.name().equals(enumName);
}
});
}
In second method I use guava (Google Guava) library which provides very useful Iterables class. Using the Iterables.any() method we can check if a given value exists in a list object. This method needs two parameters: a list and Predicate object. First I used Arrays.asList() method to create a list with all enums. After that I created new Predicate object which is used to check if a given element (enum in our case) satisfies the condition in apply method. If that happens, method Iterables.any() returns true value.
Can you try this?
SELECT [Title], [Firstname], [Surname], [Company_name], [Interest]
FROM [dbo].[EXTRANET_users]
WHERE CAST(Submission_date AS DATE) = CAST(GETDATE() AS DATE)
T-SQL doesn't really have the "implied" casting like C# does - you need to explicitly use CAST
(or CONVERT
).
Also, use GETDATE()
or CURRENT_TIMESTAMP
to get the "now" date and time.
Update: since you're working against SQL Server 2000 - none of those approaches so far work. Try this instead:
SELECT [Title], [Firstname], [Surname], [Company_name], [Interest]
FROM [dbo].[EXTRANET_users]
WHERE DATEADD(dd, 0, DATEDIFF(dd, 0, submission_date)) = DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
Do something like this:
A <div>
with ID of #imageDIV
, another one with ID #download
and a hidden <div>
with ID #previewImage
.
Include the latest version of jquery, and jspdf.debug.js from the jspdf CDN
Then add this script:
var element = $("#imageDIV"); // global variable
var getCanvas; // global variable
$('document').ready(function(){
html2canvas(element, {
onrendered: function (canvas) {
$("#previewImage").append(canvas);
getCanvas = canvas;
}
});
});
$("#download").on('click', function () {
var imgageData = getCanvas.toDataURL("image/png");
// Now browser starts downloading it instead of just showing it
var newData = imageData.replace(/^data:image\/png/, "data:application/octet-stream");
$("#download").attr("download", "image.png").attr("href", newData);
});
The div will be saved as a PNG on clicking the #download
Check that :
Additionally, you can look at the error.log file (usually located at /var/log/apache2/error.log
) which will describe why you get the 403 error exactly.
Finally, you may want to restart apache, just to be sure all that configuration is applied.
This can be generally done with /etc/init.d/apache2 restart
. On some system, the script will be called httpd. Just figure out.
As mentionned in this post pandas: how to store a list in a dataframe?; the dtypes in the dataframe may influence the results, as well as calling a dataframe or not to be assigned to.
This should work, at least according to the Search Filter Syntax article on MSDN network.
The "hang-up" you have noticed is probably just a delay. Try running the same query with narrower scope (for example the specific OU where the test object is located), as it may take very long time for processing if you run it against all AD objects.
You may also try separating the filter into two parts:
(|(displayName=*searchstring)(displayName=searchstring*))
You can use the below Code
public static class ExtensionMethods
{
public static IEnumerable<T> GetAll<T>(this Control control)
{
var controls = control.Controls.Cast<Control>();
return controls.SelectMany(ctrl => ctrl.GetAll<T>())
.Concat(controls.OfType<T>());
}
}
Oh, god! After spending several hours and downloading the Android sources, I have finally come to a solution.
If you look at the Activity class, you will see, that finish()
method only sends back the result if there is a mParent
property set to null
. Otherwise the result is lost.
public void finish() {
if (mParent == null) {
int resultCode;
Intent resultData;
synchronized (this) {
resultCode = mResultCode;
resultData = mResultData;
}
if (Config.LOGV) Log.v(TAG, "Finishing self: token=" + mToken);
try {
if (ActivityManagerNative.getDefault()
.finishActivity(mToken, resultCode, resultData)) {
mFinished = true;
}
} catch (RemoteException e) {
// Empty
}
} else {
mParent.finishFromChild(this);
}
}
So my solution is to set result to the parent activity if present, like that:
Intent data = new Intent();
[...]
if (getParent() == null) {
setResult(Activity.RESULT_OK, data);
} else {
getParent().setResult(Activity.RESULT_OK, data);
}
finish();
I hope that will be helpful if someone looks for this problem workaround again.
So here is the controller code.
public IActionResult AddURLTest()
{
return ViewComponent("AddURL");
}
You can load it using JQuery load method.
$(document).ready (function(){
$("#LoadSignIn").click(function(){
$('#UserControl').load("/Home/AddURLTest");
});
});

My sol :
<input oninput="turnOnPasswordStyle()" id="inputpassword" type="text">
function turnOnPasswordStyle(){
$('#inputpassword').attr('type', "password");
}
shouldn't you use "file://C:/localfile.jpg" instead of "C:/localfile.jpg"?
To sum it all up, the correct answer is :
select * from db where Date >= '20100401' (Format of date yyyymmdd)
This will avoid any problem with other language systems and will use the index.

OutOfDisk Unknown Sat, 28 Dec 2016 12:56:01 +0000 Sat, 28 Dec 2016 12:56:41 +0000 NodeStatusUnknown Kubelet stopped posting node status.
Ready Unknown Sat, 28 Dec 2016 12:56:01 +0000 Sat, 28 Dec 2016 12:56:41 +0000 NodeStatusUnknown Kubelet stopped posting node status.
There is a OutOfDisk on my node, then Kubelet stopped posting node status.
So, I must free some disk space, using the command of df
on my Ubuntu14.04 I can check the details of memory, and using the command of docker rmi image_id/image_name
under the role of su
I can remove the useless images.
Login in 192.168.1.157
by using ssh, like ssh [email protected]
, and switch to the 'su' by sudo su
;
/etc/init.d/kubelet restart
Result:
stop: Unknown instance:
kubelet start/running, process 59261
On the master:
kubectl get nodes
Result:
NAME STATUS AGE
192.168.1.157 Ready 42d
192.168.1.158 Ready 42d
192.168.1.159 Ready 42d
Ok, that node works fine.
Here is a reference: Kubernetes
Simple example:
public function productsAction()
{
$saveFileName = 'ceneo.xml';
$filename = $this->path . $saveFileName;
if(file_exists($filename)) {
$reader = new XMLReader();
$reader->open($filename);
$countElements = 0;
while($reader->read()) {
if($reader->nodeType == XMLReader::ELEMENT) {
$nodeName = $reader->name;
}
if($reader->nodeType == XMLReader::TEXT && !empty($nodeName)) {
switch ($nodeName) {
case 'id':
var_dump($reader->value);
break;
}
}
if($reader->nodeType == XMLReader::END_ELEMENT && $reader->name == 'offer') {
$countElements++;
}
}
$reader->close();
exit(print('<pre>') . var_dump($countElements));
}
}
Maybe these examples will help illustrate what in
does. It basically translate to Is this item in this other item?
listOfNums = [ 1, 2, 3, 4, 5, 6, 45, 'j' ]
>>> 3 in listOfNums:
>>> True
>>> 'j' in listOfNums:
>>> True
>>> 66 in listOfNums:
>>> False
Simpliest way for my opinion
var web = new WebClient();
var url = $"{hostname}/LoadDataSync?systemID={systemId}";
var responseString = web.DownloadString(url);
OR
var bytes = web.DownloadData(url);
There are a number of different options, based on what exactly the effect you're going for is. Chris Coyier did a piece on just this way back when. Worth a read:
I wrote ublame
python tool that returns a naive history of a file commits that impacted a given search term, you'll find more information on the þroject page.
You need to fix the source of the string in the first place.
A string in .NET is actually just an array of 16-bit unicode code-points, characters, so a string isn't in any particular encoding.
It's when you take that string and convert it to a set of bytes that encoding comes into play.
In any case, the way you did it, encoded a string to a byte array with one character set, and then decoding it with another, will not work, as you see.
Can you tell us more about where that original string comes from, and why you think it has been encoded wrong?
strip()
returns the string after removing leading and trailing whitespace. see doc
In your case, you may want to try replace():
string2 = string1.replace('\n', '')
