It seems you (and/or your company) have a fundamental misunderstanding of what a family tree is supposed to be.
Let me clarify, I also work for a company that has (as one of its products) a family tree in its portfolio, and we have been struggling with similar problems.
The problem, in our case, and I assume your case as well, comes from the GEDCOM format that is extremely opinionated about what a family should be. However this format contains some severe misconceptions about what a family tree really looks like.
GEDCOM has many issues, such as incompatibility with same sex relations, incest, etc... Which in real life happens more often than you'd imagine (especially when going back in time to the 1700-1800).
We have modeled our family tree to what happens in the real world: Events (for example, births, weddings, engagement, unions, deaths, adoptions, etc.). We do not put any restrictions on these, except for logically impossible ones (for example, one can't be one's own parent, relations need two individuals, etc...)
The lack of validations gives us a more "real world", simpler and more flexible solution.
As for this specific case, I would suggest removing the assertions as they do not hold universally.
For displaying issues (that will arise) I would suggest drawing the same node as many times as needed, hinting at the duplication by lighting up all the copies on selecting one of them.
In .net VB - you could achieve control over columns and rows with the following in your razor file:
@Html.EditorFor(Function(model) model.generalNotes, New With {.htmlAttributes = New With {.class = "someClassIfYouWant", .rows = 5,.cols=6}})
To make an exact copy, permissions, ownership, and all use "-a" with "cp". "-r" will copy the contents of the files but not necessarily keep other things the same.
cp -av Source/* Dest/
(make sure Dest/ exists first)
If you want to repeatedly update from one to the other or make sure you also copy all dotfiles, rsync
is a great help:
rsync -av --delete Source/ Dest/
This is also "recoverable" in that you can restart it if you abort it while copying. I like "-v" because it lets you watch what is going on but you can omit it.
I'd like to offer an updated Python 3 version of Vishal's excellent answer, which was using Python 2, along with some explanation of the adaptations / changes, which may have been already mentioned.
from io import BytesIO
from zipfile import ZipFile
import urllib.request
url = urllib.request.urlopen("http://www.unece.org/fileadmin/DAM/cefact/locode/loc162txt.zip")
with ZipFile(BytesIO(url.read())) as my_zip_file:
for contained_file in my_zip_file.namelist():
# with open(("unzipped_and_read_" + contained_file + ".file"), "wb") as output:
for line in my_zip_file.open(contained_file).readlines():
print(line)
# output.write(line)
Necessary changes:
StringIO
module in Python 3 (it's been moved to io.StringIO
). Instead, I use io.BytesIO
]2, because we will be handling a bytestream -- Docs, also this thread.urllib.urlopen
function from Python 2.6 and earlier has been discontinued; urllib.request.urlopen()
corresponds to the old urllib2.urlopen
.", Docs and this thread.Note:
b'some text'
. This is expected, as they aren't strings - remember, we're reading a bytestream. Have a look at Dan04's excellent answer.A few minor changes I made:
with ... as
instead of zipfile = ...
according to the Docs..namelist()
to cycle through all the files in the zip and print their contents.ZipFile
object into the with
statement, although I'm not sure if that's better."unzipped_and_read_"
to the beginning of the filename and a ".file"
extension (I prefer not to use ".txt"
for files with bytestrings). The indenting of the code will, of course, need to be adjusted if you want to use it.
"wb"
; I have a feeling that writing binary opens a can of worms anyway...What I didn't do:
Here's a way:
import urllib.request
import shutil
with urllib.request.urlopen("http://www.unece.org/fileadmin/DAM/cefact/locode/2015-2_UNLOCODE_SecretariatNotes.pdf") as response, open("downloaded_file.pdf", 'w') as out_file:
shutil.copyfileobj(response, out_file)
This is a destructor. It's called when the object is destroyed (out of life scope or deleted).
To be clear, you have to use ~NameOfTheClass like for the constructor, other names are invalid.
SELECT from_unixtime( UNIX_TIMESTAMP(fild_with_timestamp) ) from "your_table"
This work for me
When the servlet container (like Apache Tomcat) starts up, it will read from the web.xml file (only one per application) if anything goes wrong or shows up an error at container side console, otherwise, it will deploy and load all web applications by using web.xml (so named it as deployment descriptor).
During instantiation phase of the servlet, servlet instance is ready but it cannot serve the client request because it is missing with two pieces of information:
1: context information
2: initial configuration information
Servlet engine creates servletConfig interface object encapsulating the above missing information into it servlet engine calls init() of the servlet by supplying servletConfig object references as an argument. Once init() is completely executed servlet is ready to serve the client request.
A)only once (for every client request a new thread is created) only one instance of the servlet serves any number of the client request ie, after serving one client request server does not die. It waits for other client requests ie what CGI (for every client request a new process is created) limitation is overcome with the servlet (internally servlet engine creates the thread).
A)whenever getSession() is called on HttpServletRequest object
Step 1: request object is evaluated for incoming session ID.
Step 2: if ID not available a brand new HttpSession object is created and its corresponding session ID is generated (ie of HashTable) session ID is stored into httpservlet response object and the reference of HttpSession object is returned to the servlet (doGet/doPost).
Step 3: if ID available brand new session object is not created session ID is picked up from the request object search is made in the collection of sessions by using session ID as the key.
Once the search is successful session ID is stored into HttpServletResponse and the existing session object references are returned to the doGet() or doPost() of UserDefineservlet.
1)when control leaves from servlet code to client don't forget that session object is being held by servlet container ie, the servlet engine
2)multithreading is left to servlet developers people for implementing ie., handle the multiple requests of client nothing to bother about multithread code
A servlet is created when the application starts (it is deployed on the servlet container) or when it is first accessed (depending on the load-on-startup setting) when the servlet is instantiated, the init() method of the servlet is called then the servlet (its one and only instance) handles all requests (its service() method being called by multiple threads). That's why it is not advisable to have any synchronization in it, and you should avoid instance variables of the servlet when the application is undeployed (the servlet container stops), the destroy() method is called.
For finding value use below
if let a = companies["AAPL"] {
// a is the value
}
For traversing through the dictionary
for (key, value) in companies {
print(key,"---", value)
}
Finally for searching key by value you firstly add the extension
extension Dictionary where Value: Equatable {
func findKey(forValue val: Value) -> Key? {
return first(where: { $1 == val })?.key
}
}
Then just call
companies.findKey(val : "Apple Inc")
At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut
is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.
What about this? I presume it can be counted on to handle dates before 1970 and after 2038.
target_date_time_ms = 200000 # or whatever
base_datetime = datetime.datetime( 1970, 1, 1 )
delta = datetime.timedelta( 0, 0, 0, target_date_time_ms )
target_date = base_datetime + delta
as mentioned in the Python standard lib:
fromtimestamp() may raise ValueError, if the timestamp is out of the range of values supported by the platform C localtime() or gmtime() functions. It’s common for this to be restricted to years in 1970 through 2038.
I thought I had this configured but it turns out I set the URL in the wrong place. I followed the URL provided in the Google error page and added my URL here. Stupid mistake from my part, but easily done. Hope this helps
Might help someone:
when you have a formGroup in a modal (entrycomponent), then you have to import ReactiveFormsModule also in the module where the modal is instantiated.
In order to avoid having to fully specify the git push command you could alternatively modify your git config file:
[remote "gerrit"]
url = https://your.gerrit.repo:44444/repo
fetch = +refs/heads/master:refs/remotes/origin/master
push = refs/heads/master:refs/for/master
Now you can simply:
git fetch gerrit
git push gerrit
This is according to Gerrit
This is the perfect kind of field to define as CHAR 36, by the way, not VARCHAR 36, since each value will have the exact same length. And you'll use less storage space, since you don't need to store the data length for each value, just the value.

Stream audio in realtime without waiting for recording to end: https://github.com/noamtcohen/AudioStreamer
This streams PCM data but you could modify the code to stream mp3 or Speex
I personally like the following Java 1.8 code:
mySwitch("YY")
.myCase("AA", (o) -> {
System.out.println(o+"aa");
})
.myCase("BB", (o) -> {
System.out.println(o+"bb");
})
.myCase("YY", (o) -> {
System.out.println(o+"yy");
})
.myCase("ZZ", (o) -> {
System.out.println(o+"zz");
});
Will output:
YYyy
The sample code uses Strings but you can use any object type, including Class. e.g. .myCase(this.getClass(), (o) -> ...
Needs the following snippet:
public Case mySwitch(Object reference) {
return new Case(reference);
}
public class Case {
private Object reference;
public Case(Object reference) {
this.reference = reference;
}
public Case myCase(Object b, OnMatchDo task) {
if (reference.equals(b)) {
task.task(reference);
}
return this;
}
}
public interface OnMatchDo {
public void task(Object o);
}
You don't want to make the function wait, because JavaScript is intended to be non-blocking. Rather return the promise at the end of the function, then the calling function can use the promise to get the server response.
var promise = query.find();
return promise;
//Or return query.find();
Thanks guys the proxy pattern really helped.....Actually I wanted to call a global function foo.. In certain pages i need do to some checks. So I did the following.
//Saving the original func
var org_foo = window.foo;
//Assigning proxy fucnc
window.foo = function(args){
//Performing checks
if(checkCondition(args)){
//Calling original funcs
org_foo(args);
}
};
Thnx this really helped me out
Use the .Clear
method.
Sheets("Test").Range("A1:C3").Clear
If you want millisecond precision, try this:
CREATE TABLE my_table (
timestamp DATETIME DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))
);
This will save the timestamp as text, though.
I've done it like this:
var input = document.querySelector('input[type="file"]')
var data = new FormData()
data.append('file', input.files[0])
data.append('user', 'hubot')
fetch('/avatars', {
method: 'POST',
body: data
})
Select EventID,count() as cnt from dbo.EventInstances group by EventID having count() > 1
Also some of common cases :
maybe you export class with "default" prefix like so
export default class Module {}
just remove it
export class Module {}
this is solve the issue for me
this happen when the fragment does not have a context ,thus the getActivity()method return null. check if you use the context before you get it,or if the Activity is not exist anymore . use context in fragment.onCreate and after api response usually case this problem
$(document).ready(function () {
$('input[type="text"]').blur(function () {
if (!$(this).val()) {
$(this).addClass('error');
} else {
$(this).removeClass('error');
}
});
});
<style>
.error {
border: 1px solid #ff0000;
}
</style>
For the allowed characters you can use
^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$
to validate a complete string that should consist of only allowed characters. Note that -
is at the end (because otherwise it'd be a range) and a few characters are escaped.
For the invalid characters you can use
[<>'"/;`%]
to check for them.
To combine both into a single regex you can use
^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])
but you'd need a regex engine that allows lookahead.

Initial answer (EL 2.1, May 2009)
As mentioned in this java forum thread:
Basically autoboxing puts an Integer object into the Map. ie:
map.put(new Integer(0), "myValue")
EL (Expressions Languages) evaluates 0 as a Long and thus goes looking for a Long as the key in the map. ie it evaluates:
map.get(new Long(0))
As a Long
is never equal to an Integer
object, it does not find the entry in the map.
That's it in a nutshell.
Dec 2009 saw the introduction of EL 2.2 with JSP 2.2 / Java EE 6, with a few differences compared to EL 2.1.
It seems ("EL Expression parsing integer as long") that:
you can call the method
intValue
on theLong
object self inside EL 2.2:
<c:out value="${map[(1).intValue()]}"/>
That could be a good workaround here (also mentioned below in Tobias Liefke's answer)
Original answer:
EL uses the following wrappers:
Terms Description Type
null null value. -
123 int value. java.lang.Long
123.00 real value. java.lang.Double
"string" ou 'string' string. java.lang.String
true or false boolean. java.lang.Boolean
JSP page demonstrating this:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page import="java.util.*" %>
<h2> Server Info</h2>
Server info = <%= application.getServerInfo() %> <br>
Servlet engine version = <%= application.getMajorVersion() %>.<%= application.getMinorVersion() %><br>
Java version = <%= System.getProperty("java.vm.version") %><br>
<%
Map map = new LinkedHashMap();
map.put("2", "String(2)");
map.put(new Integer(2), "Integer(2)");
map.put(new Long(2), "Long(2)");
map.put(42, "AutoBoxedNumber");
pageContext.setAttribute("myMap", map);
Integer lifeInteger = new Integer(42);
Long lifeLong = new Long(42);
%>
<h3>Looking up map in JSTL - integer vs long </h3>
This page demonstrates how JSTL maps interact with different types used for keys in a map.
Specifically the issue relates to autoboxing by java using map.put(1, "MyValue") and attempting to display it as ${myMap[1]}
The map "myMap" consists of four entries with different keys: A String, an Integer, a Long and an entry put there by AutoBoxing Java 5 feature.
<table border="1">
<tr><th>Key</th><th>value</th><th>Key Class</th></tr>
<c:forEach var="entry" items="${myMap}" varStatus="status">
<tr>
<td>${entry.key}</td>
<td>${entry.value}</td>
<td>${entry.key.class}</td>
</tr>
</c:forEach>
</table>
<h4> Accessing the map</h4>
Evaluating: ${"${myMap['2']}"} = <c:out value="${myMap['2']}"/><br>
Evaluating: ${"${myMap[2]}"} = <c:out value="${myMap[2]}"/><br>
Evaluating: ${"${myMap[42]}"} = <c:out value="${myMap[42]}"/><br>
<p>
As you can see, the EL Expression for the literal number retrieves the value against the java.lang.Long entry in the map.
Attempting to access the entry created by autoboxing fails because a Long is never equal to an Integer
<p>
lifeInteger = <%= lifeInteger %><br/>
lifeLong = <%= lifeLong %><br/>
lifeInteger.equals(lifeLong) : <%= lifeInteger.equals(lifeLong) %> <br>
At first check the type of columns which you want to merge. You will see one of them is string where other one is int
. Then convert it to int as following code:
df["something"] = df["something"].astype(int)
merged = df.merge[df1, on="something"]
Try the following:
$("#myanchor")[0].click()
As simple as that.
Why not use ES6?
var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
const [, ...rest] = myarray;_x000D_
console.log(rest)
_x000D_
If you are looking for the oldest date (minimum value), you'd sort and then take the first item returned. Sorry for the C#:
var min = myData.OrderBy( cv => cv.Date1 ).First();
The above will return the entire object. If you just want the date returned:
var min = myData.Min( cv => cv.Date1 );
Regarding which direction to go, re: Linq to Sql vs Linq to Entities, there really isn't much choice these days. Linq to Sql is no longer being developed; Linq to Entities (Entity Framework) is the recommended path by Microsoft these days.
From Microsoft Entity Framework 4 in Action (MEAP release) by Manning Press:
What about the future of LINQ to SQL?
It's not a secret that LINQ to SQL is included in the Framework 4.0 for compatibility reasons. Microsoft has clearly stated that Entity Framework is the recommended technology for data access. In the future it will be strongly improved and tightly integrated with other technologies while LINQ to SQL will only be maintained and little evolved.

It can be done multiple ways, continuing to edit this answer for spreading better knowledge perspective.
1) Reset hard
If you are working from remote develop branch, you can reset HEAD to the last commit on remote branch as below:
git reset --hard origin/develop
2) Delete current branch, and checkout again from the remote repository
Considering, you are working on develop branch in local repo, that syncs with remote/develop branch, you can do as below:
git branch -D develop
git checkout -b develop origin/develop
3) Abort Merge
If you are in-between a bad merge (mistakenly done with wrong branch), and wanted to avoid the merge to go back to the branch latest as below:
git merge --abort
4) Abort Rebase
If you are in-between a bad rebase, you can abort the rebase request as below:
git rebase --abort

See this similar question and answer to searching with case insensitivity - SQL server ignore case in a where expression
Try using something like:
SELECT DISTINCT COL_NAME
FROM myTable
WHERE COL_NAME COLLATE SQL_Latin1_General_CP1_CI_AS LIKE '%priceorder%'
It is in visual studio. In the designer page, it is on in the menu bar, there is XTRAREPORTS field. You can show up panels using it
I would use cron to run a script every minute, and make that script run your script four times with a 15-second sleep between runs.
(That assumes your script is quick to run - you could adjust the sleep times if not.)
That way, you get all the benefits of cron
as well as your 15 second run period.
Edit: See also @bmb's comment below.
There is a simple hack to this:
Insert a hidden input field in the form with an entity which only occur in the character set the server your posting (or doing a GET) to accepts.
Example: If the form is located on a server serving ISO-8859-1 and the form will post to a server expecting UTF-8 insert something like this in the form:
<input name="iehack" type="hidden" value="☠" />
IE will then "detect" that the form contains a UTF-8 character and use UTF-8 when you POST or GET. Strange, but it does work.
Whatever algebra you are doing in Excel to create the new column could probably be done more effectively in R.
Please try the following: Read the raw file (before any excel manipulation) into R using read.csv(... stringsAsFactors=FALSE)
. [If that does not work, please take a look at ?read.table
(which read.csv
wraps), however there may be some other underlying issue].
For example:
delim = "," # or is it "\t" ?
dec = "." # or is it "," ?
myDataFrame <- read.csv("path/to/file.csv", header=TRUE, sep=delim, dec=dec, stringsAsFactors=FALSE)
Then, let's say your numeric columns is column 4
myDataFrame[, 4] <- as.numeric(myDataFrame[, 4]) # you can also refer to the column by "itsName"
This way it works`
if ($result_array)
to_excel($result_array->result_array(), $xls,$campos);
else {
echo "<script>alert('There are no fields to generate a report');</script>";
echo "<script>redirect('admin/ahm/panel'); </script>";
}`
sed cannot match \n because the trailing newline is removed before the line is put into the pattern space but can match \r, so you can convert \r\n (dos) to \n (unix) by removing \r
sed -i 's/\r//g' file
Warning: this will change the original file
However, you cannot change from unix EOL to dos or old mac (\r) by this. More readings here:
Open terminal emulator on the phone: then
adb shell
after that daemon is started
su
mount -o rw,remount /mnt/sdcard
then the read only is converted into the read-Write.
This seems to be due to a problem in the UITableViewController
subclass template. It comes with a version of the prepareForSegue
method that would require you to unwrap the segue.
Replace your current prepareForSegue
function with:
override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
if (segue.identifier == "Load View") {
// pass data to next view
}
}
This version implicitly unwraps the parameters, so you should be fine.
This should work for SQL Server:
SELECT * FROM myTable
WHERE month = DATEPART(m, GETDATE()) AND
year = DATEPART(yyyy, GETDATE())
You can query the ALL_OBJECTS view:
select owner
, object_name
, object_type
from ALL_OBJECTS
where object_name = 'FOO'
To find synonyms:
select *
from ALL_SYNONYMS
where synonym_name = 'FOO'
Just to clarify, if a user user's SQL statement references an object name with no schema qualification (e.g. 'FOO'), Oracle FIRST checks the user's schema for an object of that name (including synonyms in that user's schema). If Oracle can't resolve the reference from the user's schema, Oracle then checks for a public synonym.
If you are looking specifically for constraints on a particular table_name:
select c.*
from all_constraints c
where c.table_name = 'FOO'
union all
select cs.*
from all_constraints cs
join all_synonyms s
on (s.table_name = cs.table_name
and s.table_owner = cs.owner
and s.synonym_name = 'FOO'
)
HTH
-- addendum:
If your user is granted access to the DBA_ views (e.g. if your user has been granted SELECT_CATALOG_ROLE), you can substitute 'DBA_
' in place of 'ALL_
' in the preceding SQL examples. The ALL_x
views only show objects which you have been granted privileges. The DBA_x
views will show all database objects, whether you have privileges on them or not.
Most of the answers on this thread are either complex or will result in deadlock.

You can do this easily manually for each column like this:
df['A_perc'] = df['A']/df['sum']
If you want to do this in one step for all columns, you can use the div
method (http://pandas.pydata.org/pandas-docs/stable/basics.html#matching-broadcasting-behavior):
ds.div(ds['sum'], axis=0)
And if you want this in one step added to the same dataframe:
>>> ds.join(ds.div(ds['sum'], axis=0), rsuffix='_perc')

That's right. If you create a shelf, other people doing a get latest won't see your code.
It puts your code changes onto the server, which is probably better backed up than your work PC.
It enables you to pick up your changes on another machine, should you feel the urge to work from home.
Others can see your shelves (though I think this may be optional) so they can review your code prior to a check-in.

You will need to do an Ajax call I suspect. Here is an example of an Ajax called made by jQuery to get you started. The Code logs in a user to my system but returns a bool as to whether it was successful or not. Note the ScriptMethod and WebMethod attributes on the code behind method.
in markup:
var $Username = $("#txtUsername").val();
var $Password = $("#txtPassword").val();
//Call the approve method on the code behind
$.ajax({
type: "POST",
url: "Pages/Mobile/Login.aspx/LoginUser",
data: "{'Username':'" + $Username + "', 'Password':'" + $Password + "' }", //Pass the parameter names and values
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
error: function (jqXHR, textStatus, errorThrown) {
alert("Error- Status: " + textStatus + " jqXHR Status: " + jqXHR.status + " jqXHR Response Text:" + jqXHR.responseText) },
success: function (msg) {
if (msg.d == true) {
window.location.href = "Pages/Mobile/Basic/Index.aspx";
}
else {
//show error
alert('login failed');
}
}
});
In Code Behind:
/// <summary>
/// Logs in the user
/// </summary>
/// <param name="Username">The username</param>
/// <param name="Password">The password</param>
/// <returns>true if login successful</returns>
[WebMethod, ScriptMethod]
public static bool LoginUser( string Username, string Password )
{
try
{
StaticStore.CurrentUser = new User( Username, Password );
//check the login details were correct
if ( StaticStore.CurrentUser.IsAuthentiacted )
{
//change the status to logged in
StaticStore.CurrentUser.LoginStatus = Objects.Enums.LoginStatus.LoggedIn;
//Store the user ID in the list of active users
( HttpContext.Current.Application[ SessionKeys.ActiveUsers ] as Dictionary<string, int> )[ HttpContext.Current.Session.SessionID ] = StaticStore.CurrentUser.UserID;
return true;
}
else
{
return false;
}
}
catch ( Exception ex )
{
return false;
}
}
componentDidUpdate(prevProps){
if (this.state.authToken==null&&prevProps.authToken==null) {
AccountKit.getCurrentAccessToken()
.then(token => {
if (token) {
AccountKit.getCurrentAccount().then(account => {
this.setState({
authToken: token,
loggedAccount: account
});
});
} else {
console.log("No user account logged");
}
})
.catch(e => console.log("Failed to get current access token", e));
}
}
I knew tree
was an appropriate, but I didn't have tree installed. So, I got a pretty close alternate here
find ./ | sed -e 's/[^-][^\/]*\//--/g;s/--/ |-/'
Use reduce with destructuring to sum Amount:
const traveler = [
{ description: 'Senior', Amount: 50 },
{ description: 'Senior', Amount: 50 },
{ description: 'Adult', Amount: 75 },
{ description: 'Child', Amount: 35 },
{ description: 'Infant', Amount: 25 },
];
console.log(traveler.reduce((n, {Amount}) => n + Amount, 0))
Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.
Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master
.
(From nvie.com, Vincent Driessen, post "A successful Git branching model")
Incorporating a finished feature on develop
Finished features may be merged into the develop branch to add them to the upcoming release:
$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop
The
--no-ff
flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.
Jakub Narebski also mentions the config merge.ff
:
By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set tofalse
, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the--no-ff
option from the command line).
When set to 'only
', only such fast-forward merges are allowed (equivalent to giving the--ff-only
option from the command line).
The fast-forward is the default because:
But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.
In this case, you can end up setting this kind of config file:
[branch "master"]
# This is the list of cmdline options that should be added to git-merge
# when I merge commits into the master branch.
# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.
# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.
mergeoptions = --no-commit --no-ff
The OP adds in the comments:
I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?
Jefromi answers:
I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.
To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.
More generally, I add:
it really depends on your development workflow:
- if it is linear, one branch makes sense.
- If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.
See "When should you branch?"
Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".
Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.
There is one more reason for such failure which I came to know when mine failed
This might not apply in this case but it also throws the same error and since this question comes up on top for this error, I have added this answer here.
I faced the same problem with archiving on Xcode 8.1.
X Code Version: Version 8.2.1 (8C1002)
The following fix worked on Mar 2019
1) Go to Project & Select your Project
2) Select Build Settings -
Search for "Enable Bitcode" Set option as "NO"
3) Most of version will fix this issue, for few other XCode version try this option also,
Search for "Reflection Metadata Level" Set option as "NONE"
You should be able to add the Java Development Tools by selecting 'Help' -> 'Install New Software', there you select the 'Juno' update site, then 'Programming Languages' -> 'Eclipse Java Development Tools'.
After that, you will be able to run your JUnit tests with 'Right Click' -> 'Run as' -> 'JUnit test'.
NOT STRICTLY RELATED TO TYPESCRIPT
Just to add to all the above answers, we can also use the shorthand syntax
var result = uemail || '';
This will give you the email if uemail
variable has some value and it will simply return an empty string if uemail
variable is undefined.
This gives a nice syntax for handling undefined variables and also provide a way to use a default value in case the variable is undefined.
Other than win32, if your company had set up you web outlook, you can also try PYTHON REST API, which is officially made by Microsoft. (https://msdn.microsoft.com/en-us/office/office365/api/mail-rest-operations)
On python 3.5+ there is an easier way to achieve a shallow copy by using the ** unpackaging operator. Defined by Pep 448.
>>>dict1 = {"key1": "value1", "key2": "value2"}
>>>dict2 = {**dict1}
>>>print(dict2)
{'key1': 'value1', 'key2': 'value2'}
>>>dict2["key2"] = "WHY?!"
>>>print(dict1)
{'key1': 'value1', 'key2': 'value2'}
>>>print(dict2)
{'key1': 'value1', 'key2': 'WHY?!'}
** unpackages the dictionary into a new dictionary that is then assigned to dict2.
We can also confirm that each dictionary has a distinct id.
>>>id(dict1)
178192816
>>>id(dict2)
178192600
If a deep copy is needed then copy.deepcopy() is still the way to go.
The problem is that omega
in your case is matrix
of dimensions 1 * 1
. You should convert it to a vector if you wish to multiply t(X) %*% X
by a scalar (that is omega
)
In particular, you'll have to replace this line:
omega = rgamma(1,a0,1) / L0
with:
omega = as.vector(rgamma(1,a0,1) / L0)
everywhere in your code. It happens in two places (once inside the loop and once outside). You can substitute as.vector(.)
or c(t(.))
. Both are equivalent.
Here's the modified code that should work:
gibbs = function(data, m01 = 0, m02 = 0, k01 = 0.1, k02 = 0.1,
a0 = 0.1, L0 = 0.1, nburn = 0, ndraw = 5000) {
m0 = c(m01, m02)
C0 = matrix(nrow = 2, ncol = 2)
C0[1,1] = 1 / k01
C0[1,2] = 0
C0[2,1] = 0
C0[2,2] = 1 / k02
beta = mvrnorm(1,m0,C0)
omega = as.vector(rgamma(1,a0,1) / L0)
draws = matrix(ncol = 3,nrow = ndraw)
it = -nburn
while (it < ndraw) {
it = it + 1
C1 = solve(solve(C0) + omega * t(X) %*% X)
m1 = C1 %*% (solve(C0) %*% m0 + omega * t(X) %*% y)
beta = mvrnorm(1, m1, C1)
a1 = a0 + n / 2
L1 = L0 + t(y - X %*% beta) %*% (y - X %*% beta) / 2
omega = as.vector(rgamma(1, a1, 1) / L1)
if (it > 0) {
draws[it,1] = beta[1]
draws[it,2] = beta[2]
draws[it,3] = omega
}
}
return(draws)
}
You can use
import re
s = re.search(r"\[.*?]", string)
if s:
print(s.group(0))
using javascript
<form id="frm1" action="file.php"></form>
<script>document.getElementById('frm1').submit();</script>
Use this,
DECLARE @start_date DATETIME = '2015-02-12 00:00:00.000';
DECLARE @end_date DATETIME = '2015-02-13 00:00:00.000';
WITH AllDays
AS ( SELECT @start_date AS [Date], 1 AS [level]
UNION ALL
SELECT DATEADD(DAY, 1, [Date]), [level] + 1
FROM AllDays
WHERE [Date] < @end_date )
SELECT [Date], [level]
FROM AllDays OPTION (MAXRECURSION 0)
pass the @start_date and @end_date as SP parameters.
Result:
Date level

You need
.abc,.ab {
display: none;
}
#f:hover ~ .ab {
display: block;
}
#s:hover ~ .abc {
display: block;
}
#s:hover ~ .a,
#f:hover ~ .a{
display: none;
}
Updated demo at http://jsfiddle.net/gaby/n5fzB/2/
The problem in your original CSS was that the ,
in css selectors starts a completely new selector. it is not combined.. so #f:hover ~ .abc,.a
means #f:hover ~ .abc
and .a
. You set that to display:none
so it was always set to be hidden for all .a
elements.
Just remember set method to POST in options. Here is my code

'X-MicrosoftAjax': 'Delta=true', // blah, blah, blah...

};
//console.log('options:', options);
// Create request to get data
request(options, (err, response, body) => {
if (err) {
//console.log(err);
} else {
console.log('body:', body);
}

jQuery is simply supporting the way CSS is written.
Also, it ensures that no matter how a browser returns a value, it will be understood
jQuery can equally interpret the CSS and DOM formatting of multiple-word properties. For example, jQuery understands and returns the correct value for both .css('background-color') and .css('backgroundColor').
As an additional reference for the other responses, instead of using "UTF-8" you can use:
HTTP.UTF_8
which is included since Java 4 as part of the org.apache.http.protocol library, which is included also since Android API 1.

PsExec has whatever access rights its launcher has. It runs under regular Windows access control. This means whoever launched PsExec (be it either you, the scheduler, a service etc.) does not have sufficient rights on the target machine, or the target machine is not configured correctly. The first things to do are:
If this did not solve your problem, make sure the target machine meets the minimum requirements, specified here.
If you require the hash of the body as one of the parameters in the URL and that URL is signed via a private key, then a man-in-the-middle attack would only be able to replace the body with content that would generate the same hash. Easy to do with MD5 hash values now at least and when SHA-1 is broken, well, you get the picture.
To secure the body from tampering, you would need to require a signature of the body, which a man-in-the-middle attack would be less likely to be able to break since they wouldn't know the private key that generates the signature.
There are two ways of storing a color with alpha. The first is exactly as you see it, with each component as-is. The second is to use pre-multiplied alpha, where the color values are multiplied by the alpha after converting it to the range 0.0-1.0; this is done to make compositing easier. Ordinarily you shouldn't notice or care which way is implemented by any particular engine, but there are corner cases where you might, for example if you tried to increase the opacity of the color. If you use rgba(0, 0, 0, 0)
you are less likely to to see a difference between the two approaches.
As you read through the examples below, just keep in mind this difference
true === true // true
"string" === true // false
1 === true // false
{} === true // false
But
Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true
Assertion passes when the statement passed to expect()
evaluates to true
expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass
In all other cases cases it would fail
expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail
Even though all of these statements would evaluate to true
when doing Boolean()
:
So you can think of it as 'strict' comparison
This one does exactly the same type of comparison as .toBe(true)
, but was introduced in Jasmine recently in version 3.5.0
on Sep 20, 2019
toBeTruthy
on the other hand, evaluates the output of the statement into boolean first and then does comparison
expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail
And IN ALL OTHER CASES it would pass, for example
expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass
Try:
123-(?:(apple|banana|)-|)456
That will match apple
, banana
, or a blank string, and following it there will be a 0 or 1 hyphens. I was wrong about not having a need for a capturing group. Silly me.

Maybe an interesting point to make, is the difference between priorities between both.
As far as I can tell, the ng-if directive has one of the highest (if not the highest) priority of all Angular directives. Which means: it will run FIRST before all other, lower prioritised, directives. The fact that it runs FIRST, means that effectively, the element is removed before any inner directives are processed. Or at least: that's what I make of it.
I observerd and used this in the UI I'm building for my current customer. The entire UI is quite heavily packed, and it had ng-show and ng-hide all over it. Not to go into too much detail, but I built a generic component, which could be managed using JSON config, so I had to do some switching inside the template. There is an ng-repeat present, and inside the ng-repeat, a table is shown, which has a lot of ng-shows, ng-hides and even ng-switches present. They wanted to show at least 50 repeats in the list, which would result in more or less 1500-2000 directives to be resolved. I checked the code, and the Java backend + custom JS on the front would take about 150ms to process the data, and then Angular would chew some 2-3 seconds on it, before displaying. The customer did not complain, but I was appalled :-)
In my search, I stumbled across the ng-if directive. Now, maybe it's best to point out that at the point of conceiving this UI, there was no ng-if available. Because the ng-show and ng-hide had functions in them, which returned booleans, I could easily replace them all with ng-if. By doing so, all inner directives seemed to be no longer evaluated. That meant that I dropped back to about a third of all directives being evaluated, and thus, the UI speeded up to about 500ms - 1 sec loading time. (I have no way to determine exact seconds)
Do note: the fact that the directives are not evaluated, is an educated guess about what is happening underneath.
So, in my opinion: if you need the element to be present on the page (ie: for checking the element, or whatever), but simply be hidden, use ng-show/ng-hide. In all other cases, use ng-if.
You want rows where that condition is true so you need a comma:
data[data$Ozone > 14, ]
Remove the quotes surrounding 0
and it will work.

Use the set_facecolor(color)
method of the axes
object, which you've created one of the following ways:
You created a figure and axis/es together
fig, ax = plt.subplots(nrows=1, ncols=1)
You created a figure, then axis/es later
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1) # nrows, ncols, index
You used the stateful API (if you're doing anything more than a few lines, and especially if you have multiple plots, the object-oriented methods above make life easier because you can refer to specific figures, plot on certain axes, and customize either)
plt.plot(...)
ax = plt.gca()
Then you can use set_facecolor
:
ax.set_facecolor('xkcd:salmon')
ax.set_facecolor((1.0, 0.47, 0.42))
As a refresher for what colors can be:
matplotlib.colors
Matplotlib recognizes the following formats to specify a color:
- an RGB or RGBA tuple of float values in
[0, 1]
(e.g.,(0.1, 0.2, 0.5)
or(0.1, 0.2, 0.5, 0.3)
);- a hex RGB or RGBA string (e.g.,
'#0F0F0F'
or'#0F0F0F0F'
);- a string representation of a float value in
[0, 1]
inclusive for gray level (e.g.,'0.5'
);- one of
{'b', 'g', 'r', 'c', 'm', 'y', 'k', 'w'}
;- a X11/CSS4 color name;
- a name from the xkcd color survey; prefixed with
'xkcd:'
(e.g.,'xkcd:sky blue'
);- one of
{'tab:blue', 'tab:orange', 'tab:green', 'tab:red', 'tab:purple', 'tab:brown', 'tab:pink', 'tab:gray', 'tab:olive', 'tab:cyan'}
which are the Tableau Colors from the ‘T10’ categorical palette (which is the default color cycle);- a “CN” color spec, i.e. 'C' followed by a single digit, which is an index into the default property cycle (
matplotlib.rcParams['axes.prop_cycle']
); the indexing occurs at artist creation time and defaults to black if the cycle does not include color.All string specifications of color, other than “CN”, are case-insensitive.
I'm using Oracle. If your sql returns numeric value, which is int, you need to use Convert.ToInt32(object). Here is the example below:
public int GetUsersCount(int userId)
{
using (var conn = new OracleConnection(...)){
conn.Open();
using(var command = conn.CreateCommand()){
command.CommandText = "select count(*) from users where userid = :userId";
command.AddParameter(":userId", userId);
var rowCount = command.ExecuteScalar();
return rowCount == null ? 0 : Convert.ToInt32(rowCount);
}
}
}
The command to change the shell at startup is chsh -s <path_to_shell>
. The default shells in mac OS X are installed inside the bin
directory so if you want to change to the default zsh
then you would use the following
chsh -s /bin/zsh
If you're using different version of zsh
then you might have to add that version to /etc/shells
to avoid the nonstandard shell message. For example if you want home-brew's version of zsh
then you have to add /usr/local/bin/zsh
to the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells"
and then run
chsh -s /usr/local/bin/zsh
Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed
sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" && chsh -s /usr/local/bin/zsh
Try this (see comments in code):
function fixInteger(el) {
// this is element's value selector, you should use your own
value = $(el).val();
if (value == '') {
value = 0;
}
newValue = parseInt(value);
// if new value is Nan (when input is a string with no integers in it)
if (isNaN(newValue)) {
value = 0;
newValue = parseInt(value);
}
// apply new value to element
$(el).val(newValue);
}
function fixPrice(el) {
// this is element's value selector, you should use your own
value = $(el).val();
if (value == '') {
value = 0;
}
newValue = parseFloat(value.replace(',', '.')).toFixed(2);
// if new value is Nan (when input is a string with no integers in it)
if (isNaN(newValue)) {
value = 0;
newValue = parseFloat(value).toFixed(2);
}
// apply new value to element
$(el).val(newValue);
}
In my case the solution was to simply upgrade R.
For now I have resolved the issue by using the Linux utility s3cmd. I used it like this in Python:

I've found another easy way to deal with this problem, you just need the attribute " connectToSortable:" to draggable like as below code:

For Commons Net you need to download the binary files from Commons Net download page. Then you have to extract the file and add the commons-net-2-2.jar file to some location where you can access it from your application e.g. to /lib.
If you're running your application from the command-line you'll have to define the classpath in the java command: java -cp .;lib/commons-net-2-2.jar myapp
. More info about how to set the classpath can be found from Oracle documentation. You must specify all directories and jar files you'll need in the classpath excluding those implicitely provided by the Java runtime. Notice that there is '.' in the classpath, it is used to include the current directory in case your compiled class is located in the current directory.
For more advanced reading, you might want to read about how to define the classpath for your own jar files, or the directory structure of a war file when you're creating a web application.
If you are using an IDE, such as Eclipse, you have to remember to add the library to your build path before the IDE will recognize it and allow you to use the library.
For Next button you can use xpath or cssSelector as below:
xpath for Next button: //input[@value='Next']
cssPath for Next button: input[value=Next]

kind of an old thread, but.. i do this:
$file = 'http://www.google.com';
$file_headers = @get_headers($file);
if ($file_headers) {
$exists = true;
} else {
$exists = false;
}
i like this way because you don't need to create two components just one.

An alternative way to put images in your app (for me it just worked that way):
1 - Create an assets/images folder
2 - Add your image to the new folder
3 - Register the assets folder in pubspec.yaml
4 - Use this code:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
var assetsImage = new AssetImage('assets/images/mountain.jpg'); //<- Creates an object that fetches an image.
var image = new Image(image: assetsImage, fit: BoxFit.cover); //<- Creates a widget that displays an image.
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text("Climb your mountain!"),
backgroundColor: Colors.amber[600], //<- background color to combine with the picture :-)
),
body: Container(child: image), //<- place where the image appears
),
);
}
}
Here is my simple but efficient algorithm (in C++) for calculating running median from a stream of integers:
#include<algorithm>
#include<fstream>
#include<vector>
#include<list>
using namespace std;
void runningMedian(std::ifstream& ifs, std::ofstream& ofs, const unsigned bufSize) {
if (bufSize < 1)
throw exception("Wrong buffer size.");
bool evenSize = bufSize % 2 == 0 ? true : false;
list<int> q;
vector<int> nums;
int n;
unsigned count = 0;
while (ifs.good()) {
ifs >> n;
q.push_back(n);
auto ub = std::upper_bound(nums.begin(), nums.end(), n);
nums.insert(ub, n);
count++;
if (nums.size() >= bufSize) {
auto it = std::find(nums.begin(), nums.end(), q.front());
nums.erase(it);
q.pop_front();
if (evenSize)
ofs << count << ": " << (static_cast<double>(nums[nums.size() / 2 - 1] +
static_cast<double>(nums[nums.size() / 2]))) / 2.0 << '\n';
else
ofs << count << ": " << static_cast<double>(nums[nums.size() / 2]);
}
}
}
The bufferSize
specifies the size of the numbers sequence, on which the running median must be calculated. When reading numbers from the input stream ifs
the vector of the size bufferSize
is maintained in sorted order. The median is calculated by taking the middle of the sorted vector, if bufferSize
is odd, or the sum of the two middle elements divided by 2, when bufferSize
is even. Additinally, I maintain a list of last bufferSize
elements read from input. When a new element is added, I put it in the right place in sorted vector and remove from the vector the element added bufferSize
steps before (the value of the element retained in the front of the list). In the same time I remove the old element from the list: every new element is placed on the back of the list, every old element is removed from the front. After reaching the bufferSize
, both the list and the vector stop to grow, and every insertion of a new element is compensated be deletion of an old element, placed in the list bufferSize
steps before. Note, I do not care, whether I remove from the vector exactly the element, placed bufferSize
steps before, or just an element that has the same value. For the value of median it does not matter.
All calculated median values are output in the output stream.
My personal approach, which seems to work for all cases, is testing for the presence of members that will all only be present for strings.
function isString(x) {
return (typeof x == 'string' || typeof x == 'object' && x.toUpperCase && x.substr && x.charAt && x.trim && x.replace ? true : false);
}

I'd like to know if this method has flaws, but it has served me well for years.
I've just fixed the same issue. I had a RecyclerView.Adapter
with setHasStableIds(true)
set to avoid items blinking.
I was using a duplicatable field in getItemId()
(my model has no id
field):
override fun getItemId(position: Int): Long {
// Error-prone due to possibly duplicate name.
return contacts[position].name.hashCode().toLong()
}
getItemId()
should return a unique id for each item, so the solution was to do it:
override fun getItemId(position: Int): Long {
// Contact's phone is unique, so I use it instead.
return contacts[position].phone.hashCode().toLong()
}
My proposal (accepting variable values for n):
n=100
seq 1 $n | xargs -I {} printf =
As long as you are dealing with lines, simply mark the negative matches and target the rest.
In fact, I use this trick with sed because ^((?!hede).)*$
looks not supported by it.
Mark the negative match: (e.g. lines with hede
), using a character not included in the whole text at all. An emoji could probably be a good choice for this purpose.
s/(.*hede)/\1/g
Target the rest (the unmarked strings: e.g. lines without hede
). Suppose you want to keep only the target and delete the rest (as you want):
s/^.*//g
Suppose you want to delete the target:
Mark the negative match: (e.g. lines with hede
), using a character not included in the whole text at all. An emoji could probably be a good choice for this purpose.
s/(.*hede)/\1/g
Target the rest (the unmarked strings: e.g. lines without hede
). Suppose you want to delete the target:
s/^[^].*//g
Remove the mark:
s///g
You could try something like:
char ch;
fstream fin("file", fstream::in);
while (fin >> noskipws >> ch) {
cout << ch; // Or whatever
}
This line:
layout = (LinearLayout) findViewById(R.id.statsviewlayout);
Looks for the "statsviewlayout" id in your current 'contentview'. Now you've set that here:
setContentView(new GraphTemperature(getApplicationContext()));
And i'm guessing that new "graphTemperature" does not set anything with that id.
It's a common mistake to think you can just find any view with findViewById. You can only find a view that is in the XML (or appointed by code and given an id).
The nullpointer will be thrown because the layout you're looking for isn't found, so
layout.addView(buyButton);
Throws that exception.
addition: Now if you want to get that view from an XML, you should use an inflater:
layout = (LinearLayout) View.inflate(this, R.layout.yourXMLYouWantToLoad, null);
assuming that you have your linearlayout in a file called "yourXMLYouWantToLoad.xml"
Its Got simpler with Android Studio All you need is to first choose
3.based on the type of project and library you used like (ActionBarSherlock) you may prompted special import wizard so go ahead and click next then finish. in this case it was simple one
but sometimes the debug or Run options do not work and a error msg shows like
"this project structure is not gradle based or migrate it to gradle"
something to solve this close the opened eclipse project and reopen same project through the same process as we did before with import project (eclipse adt,gradle,etc)) this time android studio gonna add all necessary gradle files and green debug option will work too. i have did this somehow accidentally but it worked, i just hope it works for you too.
You can use asdf to install and switch between multiple java versions. It has plugins for other languages as well. You can install asdf with Homebrew
brew install asdf
When asdf is configured, install java plugin
asdf plugin-add java
Pick a version to install
asdf list-all java
For example to install and configure adoptopenjdk8
asdf install java adoptopenjdk-8.0.272+10
asdf global java adoptopenjdk-8.0.272+10
And finally if needed, configure JAVA_HOME for your shell. Just add to your shell init script such as ~/.zshrc in case of zsh:
. ~/.asdf/plugins/java/set-java-home.zsh
File file = new File("E:/Responsibility.txt");
Scanner scanner = new Scanner(file);
List<Integer> integers = new ArrayList<>();
while (scanner.hasNext()) {
if (scanner.hasNextInt()) {
integers.add(scanner.nextInt());
} else {
scanner.next();
}
}
System.out.println(integers);
This works:
find ./<SOURCE_DIR>/ -type d | sed 's/\.\/<SOURCE_DIR>//g' | xargs -I {} mkdir -p <DEST_DIR>"/{}"
Just replace SOURCE_DIR and DEST_DIR.
Its very easy and simple. Do this
from dateutil.relativedelta import relativedelta
from datetime import datetime
today_date = datetime.today()
print "todays date time: %s" %today_date
one_month_ago = today_date - relativedelta(months=1)
print "one month ago date time: %s" % one_month_ago
print "one month ago date: %s" % one_month_ago.date()
Here is the output: $python2.7 main.py
todays date time: 2016-09-06 02:13:01.937121
one month ago date time: 2016-08-06 02:13:01.937121
one month ago date: 2016-08-06

The command is different depending on which backend you use. I find that this is the best way to make sure the saved pictures have the same scaling as what I view on my screen.
Since I use Canopy with the QT backend:
pylab.get_current_fig_manager().window.showMaximized()
I then call savefig() as required with an increased DPI per silvado's answer.
there's nothing wrong with your file. xlrd does not yet support xlsx (excel 2007+) files although it's purported to have supported this for some time.
2-days ago they committed a pre-alpha version to their git which integrates xlsx support. Other forums suggest that you use a DOM parser for xlsx files since the xlsx file type is just a zip archive containing XML. I have not tried this. there is another package with similar functionality as xlrd and this is called openpyxl which you can get from easy_install or pip. I have not tried this either, however, its API is supposed to be similar to xlrd.
It can happen that the cause is not that you don't find the right directory. For example, you can read from the file (even without absolute path) but it seems you cannot write into it.
In that case, it might be that you program exits before the writing can be finished.
If your program uses an event loop (like with a GUI application, e.g. QMainWindow
) it's not a problem. However, if your program exits immediately after writing to the file, you should flush the text stream, closing the file is not always enough (and it's unnecessary, as it is closed in the destructor).
stream << "something" << endl;
stream.flush();
This guarantees that the changes are committed to the file before the program continues from this instruction.
The problem seems to be that the QFile is destructed before the QTextStream. So, even if the stream is flushed in the QTextStream destructor, it's too late, as the file is already closed.
There are two kinds of cell reference, and it's really valuable to understand them well.
One is relative reference, which is what you get when you just type the cell: A5
. This reference will be adjusted when you paste or fill the formula into other cells.
The other is absolute reference, and you get this by adding dollar signs to the cell reference: $A$5
. This cell reference will not change when pasted or filled.
A cool but rarely used feature is that row and column within a single cell reference may be independent: $A5
and A$5
. This comes in handy for producing things like multiplication tables from a single formula.

As for closing the file, I think you will need to use the SDK, or if you are opening the file from code you could close the file from code once you have finished with it.
You need to download this from Microsoft: http://www.microsoft.com/en-us/download/details.aspx?id=7435.
The tool is called "Microsoft URL Rewrite Module 2.0 for IIS 7" and is described as follows by Microsoft: "URL Rewrite Module 2.0 provides a rule-based rewriting mechanism for changing requested URL’s before they get processed by web server and for modifying response content before it gets served to HTTP clients"
if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then
"nd"
else
totext({uspRptMonthlyGasRevenueByGas;1.YearTotal},'###.00')
The above logic should be what you are looking for.
You can use time.time()
or time.clock()
before and after the block you want to time.
import time
t0 = time.time()
code_block
t1 = time.time()
total = t1-t0
This method is not as exact as timeit
(it does not average several runs) but it is straightforward.
time.time()
(in Windows and Linux) and time.clock()
(in Linux) are not precise enough for fast functions (you get total = 0). In this case or if you want to average the time elapsed by several runs, you have to manually call the function multiple times (As I think you already do in you example code and timeit does automatically when you set its number argument)
import time
def myfast():
code
n = 10000
t0 = time.time()
for i in range(n): myfast()
t1 = time.time()
total_n = t1-t0
In Windows, as Corey stated in the comment, time.clock()
has much higher precision (microsecond instead of second) and is preferred over time.time()
.
Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.
To explain the differences as relevant to your posted example:
a. When you use RegisterStartupScript
, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.
Here is the rendered source of the page when you invoke the RegisterStartupScript
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<div> <span id="lblDisplayDate">Label</span>
<br />
<input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
<br />
<input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
</div>
<div>
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
</div>
<!-- Note this part -->
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
lbl.style.color = 'red';
</script>
</form>
<!-- Note this part -->
</body>
</html>
b. When you use RegisterClientScriptBlock
, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.
Here is the rendered source of the page when you invoke the RegisterClientScriptBlock
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
// Error is thrown in the next line because lbl is null.
lbl.style.color = 'green';
Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).
Edit after comments:
For instance, the following function would work:
protected void btnPostBack2_Click(object sender, EventArgs e)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<script language='javascript'>function ChangeColor() {");
sb.Append("var lbl = document.getElementById('lblDisplayDate');");
sb.Append("lbl.style.color='green';");
sb.Append("}</script>");
//Render the function definition.
if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock"))
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString());
}
//Render the function invocation.
string funcCall = "<script language='javascript'>ChangeColor();</script>";
if (!ClientScript.IsStartupScriptRegistered("JSScript"))
{
ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall);
}
}
i actually deveopped something functional for one of my projects before and here is the code :

return new Gson().fromJson(json, returnType);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
/**

public static <T> List<T> getListOfObjects(String url, Object parameterObject, Class<T[]> returnType) {

((SimpleClientHttpRequestFactory) restTemplate.getRequestFactory()).setConnectTimeout(2000);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<T> entity = new HttpEntity<T>((T) parameterObject, headers);
ResponseEntity<Object[]> results = restTemplate.exchange(url, org.springframework.http.HttpMethod.POST, entity, Object[].class);

T[] arr = new Gson().fromJson(json, returnType);
return Arrays.asList(arr);

e.printStackTrace();
return null;
}
}
I hope that this will help somebody !
2.51 * 100 = 250.999999999997
The int()
function simply truncates the number at the decimal point, giving 250. Use
int(round(2.51*100))
to get 251 as an integer. In general, floating point numbers cannot be represented exactly. One should therefore be careful of round-off errors. As mentioned, this is not a Python-specific problem. It's a recurring problem in all computer languages.
Here, the '\n'
left by cin, is creating issues.
do {
system("cls");
manageCustomerMenu();
cin >> choice; #This cin is leaving a trailing \n
system("cls");
switch (choice) {
case '1':
createNewCustomer();
break;
This \n
is being consumed by next getline in createNewCustomer()
. You should use getline instead -
do {
system("cls");
manageCustomerMenu();
getline(cin, choice)
system("cls");
switch (choice) {
case '1':
createNewCustomer();
break;
I think this would resolve the issue.
Apparently, Chrome addresses a key in Windows registry when it looks for a Java Environment. Since the plugin installs the JRE, this key is set to a JRE path and therefore needs to be edited if you want Chrome to work with the JDK.
regedit
to edit the registry.Edit "Path" so that it matches the corresponding dll inside your JDK installation:
REGEDIT 4
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin]
"Description"="Oracle® Next Generation Java™ Plug-In"
"GeckoVersion"="1.9"
"Path"="C:\Program Files (x86)\Java\jdk1.6.0_29\jre\bin\new_plugin\npjp2.dll"
"ProductName"="Oracle® Java™ Plug-In"
"Vendor"="Oracle Corp."
"Version"="160_29"
Save file.
The REGEDIT 4
prefix at the top of the file might only be required for Windows 7 64-bit.
You can use as below
e.preventDefault()
If this method is called, the default action of the event will not be triggered.
Also if I may suggest read this: .prop() vs .attr()
I hope it will help you,
code example:
$('a').click(function(event){
event.preventDefault();
//do what you want
}
when you want to get all image from folder then use glob()
built in function which help to get all image . But when you get all then sometime need to check that all is valid so in this case this code help you. this code will also check that it is image

2014 answer: classList.toggle()
is the standard and supported by most browsers.
Older browsers can use use classlist.js for classList.toggle():
var menu = document.querySelector('.menu') // Using a class instead, see note below.
menu.classList.toggle('hidden-phone');
As an aside, you shouldn't be using IDs (they leak globals into the JS window
object).
When you are using Vue directives, the expressions are evaluated in the context of Vue, so you don't need to wrap things in {}
.
@click
is just shorthand for v-on:click
directive so the same rules apply.
In your case, simply use @click="addToCount(item.contactID)"
Here's one for for office workers using a computer shared by others.
I did put my user path in path and created the PYTHONPATH variables in my computer's PATH variable. Its listed under Environment Variables in Computer Properties -> Advanced Settings in Windows 7.

This made it so I could use the command prompt.
Hope this helped.
Just as @Kabeer has mentioned, you can use TrimSpace and here is an example from golang documentation:
package main
import (
"fmt"
"strings"
)
func main() {
fmt.Println(strings.TrimSpace(" \t\n Hello, Gophers \n\t\r\n"))
}
If you have given same text name for both of your Id and Name properties you can give like document.getElementByName('frmMain')[index]
other wise object required error will come.And if you have only one table in your page you can use document.getElementBytag('table')[index]
.
EDIT:
You can replace the index according to your form, if its first form place 0 for index.
Suppose you have the following code:
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
public class Test {
public static void main(String[] s) {
Map<String, Boolean> whoLetDogsOut = new ConcurrentHashMap<>();
whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
}
static boolean f(String s) {
System.out.println("creating a value for \""+s+'"');
return s.isEmpty();
}
}
Then you will see the message creating a value for "snoop"
exactly once as on the second invocation of computeIfAbsent
there is already a value for that key. The k
in the lambda expression k -> f(k)
is just a placeolder (parameter) for the key which the map will pass to your lambda for computing the value. So in the example the key is passed to the function invocation.
Alternatively you could write: whoLetDogsOut.computeIfAbsent("snoop", k -> k.isEmpty());
to achieve the same result without a helper method (but you won’t see the debugging output then). And even simpler, as it is a simple delegation to an existing method you could write: whoLetDogsOut.computeIfAbsent("snoop", String::isEmpty);
This delegation does not need any parameters to be written.
To be closer to the example in your question, you could write it as whoLetDogsOut.computeIfAbsent("snoop", key -> tryToLetOut(key));
(it doesn’t matter whether you name the parameter k
or key
). Or write it as whoLetDogsOut.computeIfAbsent("snoop", MyClass::tryToLetOut);
if tryToLetOut
is static
or whoLetDogsOut.computeIfAbsent("snoop", this::tryToLetOut);
if tryToLetOut
is an instance method.
Solution: change the ReuseStrategy to never
Since this problem is very complex and there are so many different factors which can fail I was happy to find this solution in another post: How to solve org.apache.http.NoHttpResponseException
Never reuse connections: configure in org.apache.http.impl.client.AbstractHttpClient:
httpClient.setReuseStrategy(new NoConnectionReuseStrategy());
The same can be configured on a org.apache.http.impl.client.HttpClientBuilder builder:
builder.setConnectionReuseStrategy(new NoConnectionReuseStrategy());

Nice example Jolly. I updated your version which limits the character length as opposed to the number of words. I also added setting the title to the real original innerHTML , so users can hover and see what is truncated.
HTML
<div id="stuff">a reallly really really long titleasdfasdfasdfasdfasdfasdfasdfadsf</div>
JS
function cutString(id){
var text = document.getElementById(id).innerHTML;
var charsToCutTo = 30;
if(text.length>charsToCutTo){
var strShort = "";
for(i = 0; i < charsToCutTo; i++){
strShort += text[i];
}
document.getElementById(id).title = "text";
document.getElementById(id).innerHTML = strShort + "...";
}
};
cutString('stuff');

Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.
Merge your branch into master, and resolve the merge conflicts.
Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.
None of these is better than the other, they just have different trade-off patterns.
I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.
To rebase and keep the branch you would:
git checkout <branch> && git rebase <target>
In your case, check out the old branch, then
git rebase master
to get it rebuilt against master.
In general, in C++ functions have to be declared before you call them. So sometime before the definition of getSkewNormal()
, the compiler needs to see the declaration:
double integrate (double start, double stop, int numSteps, Evaluatable evalObj);
Mostly what people do is put all the declarations (only) in the header file, and put the actual code -- the definitions of the functions and methods -- into a separate source (*.cc
or *.cpp
) file. This neatly solves the problem of needing all the functions to be declared.
I was looking for some information regarding reloads on pages retrieved with POST requests, such as after submitting a method="post"
form.
To reload the page keeping the POST data, use:
window.location.reload();
To reload the page discarding the POST data (perform a GET request), use:
window.location.href = window.location.href;
Hopefully this can help others looking for the same information.
Well, I waited long enough and no answer. Finally gave up the whole update/upsert approach and went with:
ContactSchema.findOne({phone: request.phone}, function(err, contact) {
if(!err) {
if(!contact) {
contact = new ContactSchema();
contact.phone = request.phone;
}
contact.status = request.status;
contact.save(function(err) {
if(!err) {
console.log("contact " + contact.phone + " created at " + contact.createdAt + " updated at " + contact.updatedAt);
}
else {
console.log("Error: could not save contact " + contact.phone);
}
});
}
});
Does it work? Yep. Am I happy with this? Probably not. 2 DB calls instead of one.
Hopefully a future Mongoose implementation would come up with a Model.upsert
function.
Here's what I ended up with. It's a listing of all properties and methods, and I listed all parameters for each method. I didn't succeed on getting all of the values.
foreach(System.Reflection.AssemblyName an in System.Reflection.Assembly.GetExecutingAssembly().GetReferencedAssemblies()){
System.Reflection.Assembly asm = System.Reflection.Assembly.Load(an.ToString());
foreach(Type type in asm.GetTypes()){
//PROPERTIES
foreach (System.Reflection.PropertyInfo property in type.GetProperties()){
if (property.CanRead){
Response.Write("<br>" + an.ToString() + "." + type.ToString() + "." + property.Name);
}
}
//METHODS
var methods = type.GetMethods();
foreach (System.Reflection.MethodInfo method in methods){
Response.Write("<br><b>" + an.ToString() + "." + type.ToString() + "." + method.Name + "</b>");
foreach (System.Reflection.ParameterInfo param in method.GetParameters())
{
Response.Write("<br><i>Param=" + param.Name.ToString());
Response.Write("<br> Type=" + param.ParameterType.ToString());
Response.Write("<br> Position=" + param.Position.ToString());
Response.Write("<br> Optional=" + param.IsOptional.ToString() + "</i>");
}
}
}
}
MySQL 8.0.23 onwards now support CIDR notation also.
So, basically:
-- CIDR Notation
GRANT ... TO 'user'@'192.168.1.0/24' IDENTIFIED BY ...
-- Netmask Notation
GRANT ... TO 'user'@'192.168.1.0/255.255.255.0' IDENTIFIED BY ...
what you are searching for is the Export-Csv file.csv
try using Get-Help Export-Csv to see whats possible
also Out-File -FilePath "file.csv"
will work
First of all we will get source and destination points between which we have to draw route. Then we will pass these attribute to below function.
public String makeURL (double sourcelat, double sourcelog, double destlat, double destlog ){
StringBuilder urlString = new StringBuilder();
urlString.append("http://maps.googleapis.com/maps/api/directions/json");
urlString.append("?origin=");// from
urlString.append(Double.toString(sourcelat));
urlString.append(",");
urlString.append(Double.toString( sourcelog));
urlString.append("&destination=");// to
urlString.append(Double.toString( destlat));
urlString.append(",");
urlString.append(Double.toString( destlog));
urlString.append("&sensor=false&mode=driving&alternatives=true");
urlString.append("&key=YOUR_API_KEY");
return urlString.toString();
}
This function will make the url that we will send to get Direction API response. Then we will parse that response . The parser class is
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public String getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
json = sb.toString();
is.close();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
return json;
}
}
This parser will return us string. We will call it like that.
JSONParser jParser = new JSONParser();
String json = jParser.getJSONFromUrl(url);
Now we will send this string to our drawpath function. The drawpath function is
public void drawPath(String result) {
try {
//Tranform the string into a json object
final JSONObject json = new JSONObject(result);
JSONArray routeArray = json.getJSONArray("routes");
JSONObject routes = routeArray.getJSONObject(0);
JSONObject overviewPolylines = routes.getJSONObject("overview_polyline");
String encodedString = overviewPolylines.getString("points");
List<LatLng> list = decodePoly(encodedString);
Polyline line = mMap.addPolyline(new PolylineOptions()
.addAll(list)
.width(12)
.color(Color.parseColor("#05b1fb"))//Google maps blue color
.geodesic(true)
);
/*
for(int z = 0; z<list.size()-1;z++){
LatLng src= list.get(z);
LatLng dest= list.get(z+1);
Polyline line = mMap.addPolyline(new PolylineOptions()
.add(new LatLng(src.latitude, src.longitude), new LatLng(dest.latitude, dest.longitude))
.width(2)
.color(Color.BLUE).geodesic(true));
}
*/
}
catch (JSONException e) {
}
}
Above code will draw the path on mMap. The code of decodePoly is
private List<LatLng> decodePoly(String encoded) {
List<LatLng> poly = new ArrayList<LatLng>();
int index = 0, len = encoded.length();
int lat = 0, lng = 0;
while (index < len) {
int b, shift = 0, result = 0;
do {
b = encoded.charAt(index++) - 63;
result |= (b & 0x1f) << shift;
shift += 5;
} while (b >= 0x20);
int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
lat += dlat;
shift = 0;
result = 0;
do {
b = encoded.charAt(index++) - 63;
result |= (b & 0x1f) << shift;
shift += 5;
} while (b >= 0x20);
int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
lng += dlng;
LatLng p = new LatLng( (((double) lat / 1E5)),
(((double) lng / 1E5) ));
poly.add(p);
}
return poly;
}
As direction call may take time so we will do all this in Asynchronous task. My Asynchronous task was
private class connectAsyncTask extends AsyncTask<Void, Void, String>{
private ProgressDialog progressDialog;
String url;
connectAsyncTask(String urlPass){
url = urlPass;
}
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMessage("Fetching route, Please wait...");
progressDialog.setIndeterminate(true);
progressDialog.show();
}
@Override
protected String doInBackground(Void... params) {
JSONParser jParser = new JSONParser();
String json = jParser.getJSONFromUrl(url);
return json;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
progressDialog.hide();
if(result!=null){
drawPath(result);
}
}
}
I hope it will help.
I tried all the solutions mentioned above, then did not work. I have 3 tables one below the other. The last one over flowed. I fixed it using:
/* Grid Definition */
table {
word-break: break-word;
}
For IE11 in edge mode, you need to set this to word-break:break-all
This is impossible as you cannot return from an asynchronous call inside a synchronous method.
In this case you need to pass a callback to foo that will receive the return value
function foo(address, fn){
geocoder.geocode( { 'address': address}, function(results, status) {
fn(results[0].geometry.location);
});
}
foo("address", function(location){
alert(location); // this is where you get the return value
});
The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.
If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.
Web Service is based on SOAP and return data in XML form. It support only HTTP protocol. It is not open source but can be consumed by any client that understands xml. It can be hosted only on IIS.
WCF is also based on SOAP and return data in XML form. It is the evolution of the web service(ASMX) and support various protocols like TCP, HTTP, HTTPS, Named Pipes, MSMQ. The main issue with WCF is, its tedious and extensive configuration. It is not open source but can be consumed by any client that understands xml. It can be hosted with in the applicaion or on IIS or using window service.
To Enable the Bluetooth you could use either of the following functions:
public void enableBT(View view){
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (!mBluetoothAdapter.isEnabled()){
Intent intentBtEnabled = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
// The REQUEST_ENABLE_BT constant passed to startActivityForResult() is a locally defined integer (which must be greater than 0), that the system passes back to you in your onActivityResult()
// implementation as the requestCode parameter.
int REQUEST_ENABLE_BT = 1;
startActivityForResult(intentBtEnabled, REQUEST_ENABLE_BT);
}
}
The second function is:
public void enableBT(View view){
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (!mBluetoothAdapter.isEnabled()){
mBluetoothAdapter.enable();
}
}
The difference is that the first function makes the app ask the user a permission to turn on the Bluetooth or to deny. The second function makes the app turn on the Bluetooth directly.
To Disable the Bluetooth use the following function:
public void disableBT(View view){
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter.isEnabled()){
mBluetoothAdapter.disable();
}
}
NOTE/ The first function needs only the following permission to be defined in the AndroidManifest.xml file:
<uses-permission android:name="android.permission.BLUETOOTH"/>
While, the second and third functions need the following permissions:
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
int x = 1;
System.out.format("%05d",x);
if you want to print the formatted text directly onto the screen.
C99 standard on c >= '0' && c <= '9'
c >= '0' && c <= '9'
(mentioned in another answer) works because C99 N1256 standard draft 5.2.1 "Character sets" says:

ASCII is not guaranteed however.

API is like the building blocks of some puzzling game that a child plays with to join blocks in different shapes and build something they can think of.
SDK, on the other hand, is a proper workshop where all of the development tools are available, rather than pre-shaped building blocks. In a workshop you have the actual tools and you are not limited to blocks, and can therefore make your own blocks, or can create something without any blocks to begin with.
coding without an SDK or API is like making everything from scratch without a workshop - you have to even make your own tools
You don't need EXEC clause. Simply use

I encountered the same issue using Spring Boot 2.0.5.RELEASE
on Java 11.
Adding javax.xml.bind:jaxb-api:2.3.0
alone did not fix the problem. I also had to update Spring Boot to the latest Milestone 2.1.0.M2
, so I assume this will be fixed in the next official release.
Error messages don't get any clearer than this:
"Scripts may close only the windows that were opened by it."
If your script did not initiate opening the window (with something like window.open), then the script in that window is not allowed to close it. Its a security to prevent a website taking control of your browser and closing windows.
with a specific dir:
cd your_dir && curl -L https://download.calibre-ebook.com/3.19.0/calibre-3.19.0-x86_64.txz | tar zx
var stringDate = "Sunday, February 28, 2010";
var months = ["January", "February", "March"]; // You add the rest :-)
var m = /(\w+) (\d+), (\d+)/.exec(stringDate);
var date = new Date(+m[3], months.indexOf(m[1]), +m[2]);
The indexOf
method on arrays is only supported on newer browsers (i.e. not IE). You'll need to do the searching yourself or use one of the many libraries that provide the same functionality.
Also the code is lacking any error checking which should be added. (String not matching the regular expression, non existent months, etc.)
Run the path in cmd C:\Program Files (x86)\Microsoft Visual Studio\Installer>vswhere.exe
There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.
This is a good question I have seen people use Close() when they shouldn't. I looked in the source code for the Selenium Client & WebDriver C# Bindings and found the following.
webDriver.Close()
- Close the browser window that the driver has focus of webDriver.Quit()
- Calls Dispose() webDriver.Dispose()
Closes all browser windows and safely ends the sessionThe code below will dispose the driver object, ends the session and closes all browsers opened during a test whether the test fails or passes.
public IWebDriver Driver;
[SetUp]
public void SetupTest()
{
Driver = WebDriverFactory.GetDriver();
}
[TearDown]
public void TearDown()
{
if (Driver != null)
Driver.Quit();
}
In summary ensure that Quit() or Dispose() is called before exiting the program, and don't use the Close() method unless you're sure of what you're doing.
Note
I found this question when try to figure out a related problem why my VM's were running out of harddrive space. Turns out an exception was causing Quit() or Dispose() to not be called every run which then caused the appData folder to fill the hard drive. So we were using the Quit() method correctly but the code was unreachable. Summary make sure all code paths will clean up your unmanaged objects by using exception safe patterns or implement IDisposable
Also
In the case of RemoteDriver calling Quit() or Dispose() will also close the session on the Selenium Server. If the session isn't closed the log files for that session remain in memory.

You can list the tags on remote repository with ls-remote
, and then check if it's there. Supposing the remote reference name is origin
in the following.
git ls-remote --tags origin
And you can list tags local with tag
.
git tag
You can compare the results manually or in script.

How about creating extension methods that allow you to add the parameters in a fluent style like this?
string a = "http://www.somedomain.com/somepage.html"
.AddQueryParam("A", "TheValueOfA")
.AddQueryParam("B", "TheValueOfB")
.AddQueryParam("Z", "TheValueOfZ");
string b = new StringBuilder("http://www.somedomain.com/anotherpage.html")
.AddQueryParam("A", "TheValueOfA")
.AddQueryParam("B", "TheValueOfB")
.AddQueryParam("Z", "TheValueOfZ")
.ToString();
Here's the overload that uses a string
:
public static string AddQueryParam(
this string source, string key, string value)
{
string delim;
if ((source == null) || !source.Contains("?"))
{
delim = "?";
}
else if (source.EndsWith("?") || source.EndsWith("&"))
{
delim = string.Empty;
}
else
{
delim = "&";
}
return source + delim + HttpUtility.UrlEncode(key)
+ "=" + HttpUtility.UrlEncode(value);
}
And here's the overload that uses a StringBuilder
:
public static StringBuilder AddQueryParam(
this StringBuilder source, string key, string value)
{
bool hasQuery = false;
for (int i = 0; i < source.Length; i++)
{
if (source[i] == '?')
{
hasQuery = true;
break;
}
}
string delim;
if (!hasQuery)
{
delim = "?";
}
else if ((source[source.Length - 1] == '?')
|| (source[source.Length - 1] == '&'))
{
delim = string.Empty;
}
else
{
delim = "&";
}
return source.Append(delim).Append(HttpUtility.UrlEncode(key))
.Append("=").Append(HttpUtility.UrlEncode(value));
}
Try this, just an example:
u.UserTypeOptions = new SelectList(new[]
{
new { ID="1", Name="name1" },
new { ID="2", Name="name2" },
new { ID="3", Name="name3" },
}, "ID", "Name", 1);
Or
u.UserTypeOptions = new SelectList(new List<SelectListItem>
{
new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
new SelectListItem { Selected = false, Text = "Homeowner", Value = "2"},
new SelectListItem { Selected = false, Text = "Contractor", Value = "3"},
},"Value","Text");
the react docs explain this nicely in the documentation, you have to use process.env.PUBLIC_URL

Trying to handle the URI with content:// scheme by calling ContentResolver.query()

Of course, be mindful that your program will only be useful in english speaking countries if you detect dates this way. You might want to consider:
Set<String> dayNames = Calendar.getInstance()
.getDisplayNames(Calendar.DAY_OF_WEEK,
Calendar.SHORT,
Locale.getDefault())
.keySet();
From there you can use .startsWith or .matches or whatever other method that others have mentioned above. This way you get the default locale for the jvm. You could always pass in the locale (and maybe default it to the system locale if it's null) as well to be more robust.
UPDATE My Answer here is now outdated. The Joda-Time project is now in maintenance mode, advising migration to the java.time classes. See the modern solution in the Answer by Ole V.V..
The accepted answer by NidhishKrishnan is correct.
For fun, here is the same kind of code in Joda-Time 2.3.
// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;
java.util.Date date = new Date(); // A Date object coming from other code.
// Pass the java.util.Date object to constructor of Joda-Time DateTime object.
DateTimeZone kolkataTimeZone = DateTimeZone.forID( "Asia/Kolkata" );
DateTime dateTimeInKolkata = new DateTime( date, kolkataTimeZone );
DateTimeFormatter formatter = DateTimeFormat.forPattern( "yyyy-MM-dd");
System.out.println( "dateTimeInKolkata formatted for date: " + formatter.print( dateTimeInKolkata ) );
System.out.println( "dateTimeInKolkata formatted for ISO 8601: " + dateTimeInKolkata );
When run…
dateTimeInKolkata formatted for date: 2013-12-17
dateTimeInKolkata formatted for ISO 8601: 2013-12-17T14:56:46.658+05:30
It is perfectly fine if you want to go with the display: table-cell
solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;
. flex
is something which has a decent support.
.wrap {_x000D_
height: 200px;_x000D_
width: 200px;_x000D_
border: 1px solid #aaa;_x000D_
margin: 10px;_x000D_
display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
align-self: flex-end;_x000D_
}
_x000D_
<div class="wrap">_x000D_
<span>Align me to the bottom</span>_x000D_
</div>
_x000D_
In the above example, we first set the parent element to display: flex;
and later, we use align-self
to flex-end
. This helps you push the item to the end of the flex
parent.
flex
)If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell;
with vertical-align: bottom;
is enough
div {_x000D_
display: table-cell;_x000D_
vertical-align: bottom;_x000D_
border: 1px solid #f00;_x000D_
height: 100px;_x000D_
width: 100px;_x000D_
}
_x000D_
<div>Hello</div>

Change . to / as the path separator and use getResourceAsStream
:
reader = new BufferedReader(new InputStreamReader(
getClass().getClassLoader().getResourceAsStream(
"com/company/app/dao/sql/SqlQueryFile.sql")));
or
reader = new BufferedReader(new InputStreamReader(
getClass().getResourceAsStream(
"/com/company/app/dao/sql/SqlQueryFile.sql")));
Note the leading slash when using Class.getResourceAsStream()
vs ClassLoader.getResourceAsStream
.
getSystemResourceAsStream
uses the system classloader which isn't what you want.
I suspect that using slashes instead of dots would work for ClassPathResource
too.
with open("input", "rb") as input:
with open("output", "wb") as output:
while True:
data = input.read(1024)
if data == "":
break
output.write(data)
The above will read 1 kilobyte at a time, and write it. You can support incredibly large files this way, as you won't need to read the entire file into memory.
A simple answer, if the red "stop" box is not working, is to try pressing the "Ctrl + Break" buttons on the keyboard.
If you are running SQL Server on Linux, there is an app you can add to your systray called "killall" Just click on the "killall" button and then click on the program that is caught in a loop and it will terminate the program. Hope that helps.
Try this with bootstrap
<div class="row justify-content-center">
<button type="submit" class="btn btn-primary">btnText</button>
</div>

Try with this code. I hope it's useful for you.
function sleep(seconds)
{
var e = new Date().getTime() + (seconds * 1000);
while (new Date().getTime() <= e) {}
}
If it is Rails 5, because of new hash notation:
params.permit(:name, groundtruth: [:type, coordinates:[]])
will work fine.
The example in the other answer is unnecessarily complex. This would be more straightforward, if all you want to do is return the raw data objects for each document in a query or collection:
async getMarker() {
const snapshot = await firebase.firestore().collection('events').get()
return snapshot.docs.map(doc => doc.data());
}
Instead of using the instance with the scope resolution operator :: because it wasn't defined like static function.
$r=Page::getInstanceByName($page);
change it to :
$r=Page->getInstanceByName($page);
And it will work like a charm.
This can also occur if the read end of the output from your script dies prematurely
ie open.py | otherCommand
if otherCommand exits and open.py tries to write to stdout
I had a bad gawk script that did this lovely to me.
If you really need to encode UTF-8, you can try prepending the unicode byte order mark. I have no idea how widespread the support for this method is, but ZXing at least appears to support it: http://code.google.com/p/zxing/issues/detail?id=103
I've been reading up on QR Mode recently, and I think I've seen the same practice mentioned elsewhere, but I've not the foggiest where.
awk
awk '{gsub(/two.*/,"")}1' file
Ruby
ruby -ne 'print $_.gsub(/two.*/,"")' file
As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live(). Refer: http://api.jquery.com/on/
$('#imageFile').on("change", function(){ uploadFile(); });
ref.orderByChild("lead").startAt("Jack Nicholson").endAt("Jack Nicholson").listner....
This will work.
Marking a controller's session state as readonly or disabled will solve the problem.
You can decorate a controller with the following attribute to mark it read-only:
[SessionState(System.Web.SessionState.SessionStateBehavior.ReadOnly)]
the System.Web.SessionState.SessionStateBehavior enum has the following values:
When tree width is very large and depth is low use DFS as recursion stack will not overflow.Use BFS when width is low and depth is very large to traverse the tree.
I had a large enumerated type I wanted to convert it into an NSDictionary
lookup. I ended up using sed
from OSX terminal as:
$ sed -E 's/^[[:space:]]{1,}([[:alnum:]]{1,}).*$/ @(\1) : @"\1",/g' ObservationType.h
which can be read as: 'capture the first word on the line and output @(word) : @"word",'
This regex converts the enum in a header file named 'ObservationType.h' which contains:
typedef enum : int {
ObservationTypePulse = 1,
ObservationTypeRespRate = 2,
ObservationTypeTemperature = 3,
.
.
}
into something like:
@(ObservationTypePulse) : @"ObservationTypePulse",
@(ObservationTypeRespRate) : @"ObservationTypeRespRate",
@(ObservationTypeTemperature) : @"ObservationTypeTemperature",
.
.
which can then be wrapped in a method using modern objective-c syntax @{ }
(as explained by @yar1vn above) to create a NSDictionary
lookup :
-(NSDictionary *)observationDictionary
{
static NSDictionary *observationDictionary;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
observationDictionary = [[NSDictionary alloc] initWithDictionary:@{
@(ObservationTypePulse) : @"ObservationTypePulse",
@(ObservationTypeRespRate) : @"ObservationTypeRespRate",
.
.
}];
});
return observationDictionary;
}
The dispatch_once
boiler-plate is just to ensure that the static variable is initialised in a thread-safe manner.
Note: I found the sed regex expression on OSX odd - when I tried to use +
to match 'one or more' it didn't work and had to resort to using {1,}
as a replacement
