You can compute pairwise cosine similarity on the rows of a sparse matrix directly using sklearn. As of version 0.17 it also supports sparse output:
from sklearn.metrics.pairwise import cosine_similarity
from scipy import sparse
A = np.array([[0, 1, 0, 0, 1], [0, 0, 1, 1, 1],[1, 1, 0, 1, 0]])
A_sparse = sparse.csr_matrix(A)
similarities = cosine_similarity(A_sparse)
print('pairwise dense output:\n {}\n'.format(similarities))
#also can output sparse matrices
similarities_sparse = cosine_similarity(A_sparse,dense_output=False)
print('pairwise sparse output:\n {}\n'.format(similarities_sparse))
Results:
pairwise dense output:
[[ 1. 0.40824829 0.40824829]
[ 0.40824829 1. 0.33333333]
[ 0.40824829 0.33333333 1. ]]
pairwise sparse output:
(0, 1) 0.408248290464
(0, 2) 0.408248290464
(0, 0) 1.0
(1, 0) 0.408248290464
(1, 2) 0.333333333333
(1, 1) 1.0
(2, 1) 0.333333333333
(2, 0) 0.408248290464
(2, 2) 1.0
If you want column-wise cosine similarities simply transpose your input matrix beforehand:
A_sparse.transpose()
Thanks @vpekar for your implementation. It helped a lot. I just found that it misses the tf-idf weight while calculating the cosine similarity. The Counter(word) returns a dictionary which has the list of words along with their occurence.
cos(q, d) = sim(q, d) = (q · d)/(|q||d|) = (sum(qi, di)/(sqrt(sum(qi2)))*(sqrt(sum(vi2))) where i = 1 to v)
Please feel free to view my code here. But first you will have to download the anaconda package. It will automatically set you python path in Windows. Add this python interpreter in Eclipse.
There are many metrics to define similarity and distance between strings as mentioned above. I will give my 5 cents by showing an example of Jaccard similarity
with Q-Grams
and an example with edit distance
.
The libraries
from nltk.metrics.distance import jaccard_distance
from nltk.util import ngrams
from nltk.metrics.distance import edit_distance
Jaccard Similarity
1-jaccard_distance(set(ngrams('Apple', 2)), set(ngrams('Appel', 2)))
and we get:
0.33333333333333337
And for the Apple
and Mango
1-jaccard_distance(set(ngrams('Apple', 2)), set(ngrams('Mango', 2)))
and we get:
0.0
Edit Distance
edit_distance('Apple', 'Appel')
and we get:
2
And finally,
edit_distance('Apple', 'Mango')
and we get:
5
Cosine Similarity on Q-Grams (q=2)
Another solution is to work with the textdistance
library. I will provide an example of Cosine Similarity
import textdistance
1-textdistance.Cosine(qval=2).distance('Apple', 'Appel')
and we get:
0.5
From Dockerfile reference:
The
ARG
instruction defines a variable that users can pass at build-time to the builder with the docker build command using the--build-arg <varname>=<value>
flag.The
ENV
instruction sets the environment variable<key>
to the value<value>
.
The environment variables set usingENV
will persist when a container is run from the resulting image.
So if you need build-time customization, ARG
is your best choice.
If you need run-time customization (to run the same image with different settings), ENV
is well-suited.
If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable
Given the number of combinations involved, using ENV
to set those features at runtime is best here.
But you can combine both by:
ARG
ARG
as an ENV
That is, with a Dockerfile including:
ARG var
ENV var=${var}
You can then either build an image with a specific var
value at build-time (docker build --build-arg var=xxx
), or run a container with a specific runtime value (docker run -e var=yyy
)
In the first one Python has to execute one more operations than necessary(instead of just checking not equal to it has to check if it is not true that it is equal, thus one more operation). It would be impossible to tell the difference from one execution, but if run many times, the second would be more efficient. Overall I would use the second one, but mathematically they are the same
Calling savefig before show() worked for me.
fig ,ax = plt.subplots(figsize = (4,4))
sns.barplot(x='sex', y='tip', color='g', ax=ax,data=tips)
sns.barplot(x='sex', y='tip', color='b', ax=ax,data=tips)
ax.legend(['Male','Female'], facecolor='w')
plt.savefig('figure.png')
plt.show()
Eva M from above, almost had the answer as posted above (Thanks Eva M!):
var validator = $( "#myform" ).validate();
validator.form();
This is almost the answer, but it causes problems, in even the most up to date jquery validation plugin as of 13 DEC 2018. The problem is that if one directly copies that sample, and EVER calls ".validate()" more than once, the focus/key processing of the validation can get broken, and the validation may not show errors properly.
Here is how to use Eva M's answer, and ensure those focus/key/error-hiding issues do not occur:
1) Save your validator to a variable/global.
var oValidator = $("#myform").validate();
2) DO NOT call $("#myform").validate() EVER again.
If you call $("#myform").validate() more than once, it may cause focus/key/error-hiding issues.
3) Use the variable/global and call form.
var bIsValid = oValidator.form();
you can do it simply with PHP opendir
function.
example:
$handle = opendir(dirname(realpath(__FILE__)).'/pictures/');
while($file = readdir($handle)){
if($file !== '.' && $file !== '..'){
echo '<img src="pictures/'.$file.'" border="0" />';
}
}
A solution can be, if you know the key position, convert the keys into an String array and return the value in the position:
public String getKey(int pos, Map map) {
String[] keys = (String[]) map.keySet().toArray(new String[0]);
return keys[pos];
}
In my case, I forgot to tell the type controller that the response is a JSON object. response.setContentType("application/json");
For me, you can't. But if that suits your needs, you could have speed and formatting by copying the whole range at once, instead of looping:
range("B2:B5002").Copy Destination:=Sheets("Output").Cells(startrow, 2)
And, by the way, you can build a custom range string, like Range("B2:B4, B6, B11:B18")
edit: if your source is "sparse", can't you just format the destination at once when the copy is finished ?
Maybe this quick, dirty solution will work?
public class A {
static int UNIQUE_ID = 0;
int uid = ++UNIQUE_ID;
public int hashCode() {
return uid;
}
}
This also gives the number of instance of a class being initialized.

I think it's well explained here -- quoting just the key sentences of the long article:
The general concept behind a token-based authentication system is simple. Allow users to enter their username and password in order to obtain a token which allows them to fetch a specific resource - without using their username and password. Once their token has been obtained, the user can offer the token - which offers access to a specific resource for a time period - to the remote site.
In other words: add one level of indirection for authentication -- instead of having to authenticate with username and password for each protected resource, the user authenticates that way once (within a session of limited duration), obtains a time-limited token in return, and uses that token for further authentication during the session.
Advantages are many -- e.g., the user could pass the token, once they've obtained it, on to some other automated system which they're willing to trust for a limited time and a limited set of resources, but would not be willing to trust with their username and password (i.e., with every resource they're allowed to access, forevermore or at least until they change their password).
If anything is still unclear, please edit your question to clarify WHAT isn't 100% clear to you, and I'm sure we can help you further.
I will give you a better idea
for(decltype(things.size()) i = 0; i < things.size(); i++){
//...
}
decltype
is
Inspects the declared type of an entity or the type and value category of an expression.
So, It deduces type of things.size()
and i
will be a type as same as things.size()
. So,
i < things.size()
will be executed without any warning
Context is stored at the application level scope where as request is stored at page level i.e to say
Web Container brings up the applications one by one and run them inside its JVM. It stores a singleton object in its jvm where it registers anyobject that is put inside it.This singleton is shared across all applications running inside it as it is stored inside the JVM of the container itself.
However for requests, the container creates a request object that is filled with data from request and is passed along from one thread to the other (each thread is a new request that is coming to the server), also request is passed to the threads of same application.
use :
mongoimport -d 'database_name' -c 'collection_name' --type csv --headerline --file filepath/file_name.csv
You have to traverse the whole array and keep two auxiliary values:
Suppose your array is called myArray. At the end of this code minIndex has the index of the smallest value.
var min = Number.MAX_VALUE; //the largest number possible in JavaScript
var minIndex = -1;
for (int i=0; i<myArray.length; i++){
if (myArray[i] < min){
min = myArray[i];
minIndex = i;
}
}
This is assuming the worst case scenario: a totally random array. It is an O(n) algorithm or order n algorithm, meaning that if you have n elements in your array, then you have to look at all of them before knowing your answer. O(n) algorithms are the worst ones because they take a lot of time to solve the problem.
If your array is sorted or has any other specific structure, then the algorithm can be optimized to be faster.
Having said that, though, unless you have a huge array of thousands of values then don't worry about optimization since the difference between an O(n) algorithm and a faster one would not be noticeable.
Your query is close you need to join using the mgr
and the empid
on e1.mgr = e2.empid
So the full query is:
select e1.ename Emp,
e2.eName Mgr
from employees e1
inner join employees e2
on e1.mgr = e2.empid
If you want to return all rows including those without a manager then you would change it to a LEFT JOIN
(for example the president):
select e1.ename Emp,
e2.eName Mgr
from employees e1
left join employees e2
on e1.mgr = e2.empid
The president in your sample data will return a null
value for the manager because they do not have a manager.
Hat tip to Adam Bien if you don't want to use createQuery
with a String
and want type safety:
@PersistenceContext EntityManager em; public List<ConfigurationEntry> allEntries() { CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<ConfigurationEntry> cq = cb.createQuery(ConfigurationEntry.class); Root<ConfigurationEntry> rootEntry = cq.from(ConfigurationEntry.class); CriteriaQuery<ConfigurationEntry> all = cq.select(rootEntry); TypedQuery<ConfigurationEntry> allQuery = em.createQuery(all); return allQuery.getResultList(); }

All the above commands create a new branch and with the latest commit being the one specified in the command, but just in case you want your current branch HEAD
to move to the specified commit, below is the command:
git checkout <commit_hash>
It detaches and point the HEAD
to specified commit and saves from creating a new branch when the user just wants to view the branch state till that particular commit.
You then might want to go back to the latest commit & fix the detached HEAD:
I think this is what you want:
/grand/parent/child[@id="#grand"]
I would suggest to read up a bit on the syntax. See here.

First create a temp table :
Step 1:
create table #tblOm_Temp (
Name varchar(100),
Age Int ,
RollNumber bigint
)
**Step 2: ** Insert Some value in Temp table .
insert into #tblom_temp values('Om Pandey',102,1347)
Step 3: Declare a table Variable to hold temp table data.
declare @tblOm_Variable table(
Name Varchar(100),
Age int,
RollNumber bigint
)
Step 4: select value from temp table and insert into table variable.
insert into @tblOm_Variable select * from #tblom_temp
Finally value is inserted from a temp table to Table variable
Step 5: Can Check inserted value in table variable.
select * from @tblOm_Variable
You can either use a regular tuple
interface IReqularDemo: [number, string];
or if optional parameters support is needed
interface IOptionalDemo: [value1: number, value2?: string]
Just remove the slash after Data
and prepend the root:
<xsl:variable name="myVarA" select="/root/DataSet/Data[@Value1='2']/@Value2"/>

If you have a clear button, the accepted answer won't work for you. We should also guard against Apple changing things in the future by calling super
.
So, to make sure the text doesn't overlap the clear button, let's get the 'default' value from super
first, then adjust as necessary.
This code will add a 10px insets on the top, left and bottom of the text field:
@interface InsetTextField : UITextField
@end
@implementation InsetTextField
// Placeholder position
- (CGRect)textRectForBounds:(CGRect)bounds {
CGRect rect = [super textRectForBounds:bounds];
UIEdgeInsets insets = UIEdgeInsetsMake(10, 10, 10, 0);
return UIEdgeInsetsInsetRect(rect, insets);
}
// Text position
- (CGRect)editingRectForBounds:(CGRect)bounds {
CGRect rect = [super editingRectForBounds:bounds];
UIEdgeInsets insets = UIEdgeInsetsMake(10, 10, 10, 0);
return UIEdgeInsetsInsetRect(rect, insets);
}
// Clear button position
- (CGRect)clearButtonRectForBounds:(CGRect)bounds {
CGRect rect = [super clearButtonRectForBounds:bounds];
return CGRectOffset(rect, -5, 0);
}
@end
Note: UIEdgeInsetsMake takes parameters in the order: top, left, bottom, right.

Check the code below:
<input id="mail">
<script>
document.getElementById('mail').readOnly = true; // makes input readonline
document.getElementById('mail').readOnly = false; // makes input writeable again
</script>
If you want to further automate this, because you are checking your module into version control, and don't want to rely upon devs remembering to npm link, you can add this to your package.json "scripts" section:
"scripts": {
"postinstall": "npm link ../somelocallib",
"postupdate": "npm link ../somelocallib"
}
This feels beyond hacky, but it seems to "work". Got the tip from this npm issue: https://github.com/npm/npm/issues/1558#issuecomment-12444454

perhaps making mvcc permanent could solve it (as opposed to specific batch only: SET TRANSACTION ISOLATION LEVEL SNAPSHOT):
ALTER DATABASE yourDbNameHere SET READ_COMMITTED_SNAPSHOT ON;
[EDIT: October 14]
After reading this: Better concurrency in Oracle than SQL Server? and this: http://msdn.microsoft.com/en-us/library/ms175095.aspx
When the READ_COMMITTED_SNAPSHOT database option is set ON, the mechanisms used to support the option are activated immediately. When setting the READ_COMMITTED_SNAPSHOT option, only the connection executing the ALTER DATABASE command is allowed in the database. There must be no other open connection in the database until ALTER DATABASE is complete. The database does not have to be in single-user mode.
i've come to conclusion that you need to set two flags in order to activate mssql's MVCC permanently on a given database:
ALTER DATABASE yourDbNameHere SET ALLOW_SNAPSHOT_ISOLATION ON;
ALTER DATABASE yourDbNameHere SET READ_COMMITTED_SNAPSHOT ON;
One interesting example of a binary tree that hasn't been mentioned is that of a recursively evaluated mathematical expression. It's basically useless from a practical standpoint, but it is an interesting way to think of such expressions.
Basically each node of the tree has a value that is either inherent to itself or is evaluated by recursively by operating on the values of its children.
For example, the expression (1+3)*2
can be expressed as:
*
/ \
+ 2
/ \
1 3
To evaluate the expression, we ask for the value of the parent. This node in turn gets its values from its children, a plus operator and a node that simply contains '2'. The plus operator in turn gets its values from children with values '1' and '3' and adds them, returning 4 to the multiplication node which returns 8.
This use of a binary tree is akin to reverse polish notation in a sense, in that the order in which operations are performed is identical. Also one thing to note is that it doesn't necessarily have to be a binary tree, it's just that most commonly used operators are binary. At its most basic level, the binary tree here is in fact just a very simple purely functional programming language.
Use Promise.each of bluebird library.
Promise.each(
Iterable<any>|Promise<Iterable<any>> input,
function(any item, int index, int length) iterator
) -> Promise
This method iterates over an array, or a promise of an array, which contains promises (or a mix of promises and values) with the given iterator function with the signature (value, index, length) where the value is the resolved value of a respective promise in the input array. Iteration happens serially. If the iterator function returns a promise or a thenable, then the result of the promise is awaited before continuing with next iteration. If any promise in the input array is rejected, then the returned promise is rejected as well.
If all of the iterations resolve successfully, Promise.each resolves to the original array unmodified. However, if one iteration rejects or errors, Promise.each ceases execution immediately and does not process any further iterations. The error or rejected value is returned in this case instead of the original array.
This method is meant to be used for side effects.
var fileNames = ["1.txt", "2.txt", "3.txt"];
Promise.each(fileNames, function(fileName) {
return fs.readFileAsync(fileName).then(function(val){
// do stuff with 'val' here.
});
}).then(function() {
console.log("done");
});
git remote prune origin
, as suggested in the other answer, will remove all such stale branches. That's probably what you'd want in most cases, but if you want to just remove that particular remote-tracking branch, you should do:
git branch -d -r origin/coolbranch
(The -r
is easy to forget...)
-r
in this case will "List or delete (if used with -d
) the remote-tracking branches." according to the Git documentation found here: https://git-scm.com/docs/git-branch
OK, You can simply do:
git tag -a <tag> <commit-hash>
So if you want to add tag: 1.0.2 to commit e50f795
, just simply do:
git tag -a 1.0.2 e50f795
Also you add a message at the end, using -m
, something like this:
git tag -a 1.0.2 e50f795 -m "my message"
After all, you need to push it to the remote
, to do that, simply do:
git push origin 1.0.2
If you have many tags which you don't want to mention them one by one, just simply do:
git push origin --tags
to push all tags together...
Also, I created the steps in the image below, for more clarification of the steps:
You can also dd the tag in Hub or using tools like SourceTree, to avoid the previous steps, I logged-in to my Bitbucket in this case and doing it from there:

icon:Python comes with numerous ways of formatting strings:
New style .format()
, which supports a rich formatting mini-language:
>>> temperature = 10
>>> print("the furnace is now {} degrees!".format(temperature))
the furnace is now 10 degrees!
Old style %
format specifier:
>>> print("the furnace is now %d degrees!" % temperature)
the furnace is now 10 degrees!
In Py 3.6 using the new f""
format strings:
>>> print(f"the furnace is now {temperature} degrees!")
the furnace is now 10 degrees!
Or using print()
s default sep
arator:
>>> print("the furnace is now", temperature, "degrees!")
the furnace is now 10 degrees!
And least effectively, construct a new string by casting it to a str()
and concatenating:
>>> print("the furnace is now " + str(temperature) + " degrees!")
the furnace is now 10 degrees!
Or join()
ing it:
>>> print(' '.join(["the furnace is now", str(temperature), "degrees!"]))
the furnace is now 10 degrees!

In my scripts, I either use the shorthand:
window.console && console.log(...) // only log if the function exists
or, if it's not possible or feasible to edit every console.log line, I create a fake console:

// then create and empty logging function which does nothing.
//
// REMEMBER: put this before any other console.log calls
!window.console && (window.console = {} && window.console.log = function () {});

In regards to problems with Qt4, I couldn't use the qmake moc option mentioned above. But that wasn't the problem anyway. I had the following code in the class definition:
class ScreenWidget : public QGLWidget

Q_OBJECT // must include this if you use Qt signals/slots
...
};
I had to remove the line "Q_OBJECT" because I had no signals or slots defined.
There's not really anything to JSON. Curly brackets are for "objects" (associative arrays) and square brackets are for arrays without keys (numerically indexed). As far as working with it in Android, there are ready made classes for that included in the sdk (no download required).
Check out these classes: http://developer.android.com/reference/org/json/package-summary.html
I think you've pretty much nailed the points!
If you follow database design best practices and your primary key is never updatable (which I think should always be the case anyway), then you never really need the ON UPDATE CASCADE
clause.
Zed made a good point, that if you use a natural key (e.g. a regular field from your database table) as your primary key, then there might be certain situations where you need to update your primary keys. Another recent example would be the ISBN (International Standard Book Numbers) which changed from 10 to 13 digits+characters not too long ago.
This is not the case if you choose to use surrogate (e.g. artifically system-generated) keys as your primary key (which would be my preferred choice in all but the most rare occasions).
So in the end: if your primary key never changes, then you never need the ON UPDATE CASCADE
clause.

The AdamOptimizer class creates additional variables, called "slots", to hold values for the "m" and "v" accumulators.
See the source here if you're curious, it's actually quite readable: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/training/adam.py#L39 . Other optimizers, such as Momentum and Adagrad use slots too.
These variables must be initialized before you can train a model.
The normal way to initialize variables is to call tf.initialize_all_variables()
which adds ops to initialize the variables present in the graph when it is called.
(Aside: unlike its name suggests, initialize_all_variables() does not initialize anything, it only add ops that will initialize the variables when run.)
What you must do is call initialize_all_variables() after you have added the optimizer:
...build your model...
# Add the optimizer
train_op = tf.train.AdamOptimizer(1e-4).minimize(cross_entropy)
# Add the ops to initialize variables. These will include
# the optimizer slots added by AdamOptimizer().
init_op = tf.initialize_all_variables()
# launch the graph in a session
sess = tf.Session()
# Actually intialize the variables
sess.run(init_op)
# now train your model
for ...:
sess.run(train_op)
As far as I'm aware in order to format a date value you have to handle it in parameterMap,
$('#listDiv').kendoGrid({
dataSource: {
type: 'json',
serverPaging: true,
pageSize: 10,
transport: {
read: {
url: '@Url.Action("_ListMy", "Placement")',
data: refreshGridParams,
type: 'POST'
},
parameterMap: function (options, operation) {
if (operation != "read") {
var d = new Date(options.StartDate);
options.StartDate = kendo.toString(new Date(d), "dd/MM/yyyy");
return options;
}
else { return options; }
}
},
schema: {
model: {
id: 'Id',
fields: {
Id: { type: 'number' },
StartDate: { type: 'date', format: 'dd/MM/yyyy' },
Area: { type: 'string' },
Length: { type: 'string' },
Display: { type: 'string' },
Status: { type: 'string' },
Edit: { type: 'string' }
}
},
data: "Data",
total: "Count"
}
},
scrollable: false,
columns:
[
{
field: 'StartDate',
title: 'Start Date',
format: '{0:dd/MM/yyyy}',
width: 100
},
If you follow the above example and just renames objects like 'StartDate' then it should work (ignore 'data: refreshGridParams,')
For further details check out below link or just search for kendo grid parameterMap ans see what others have done.

The advantage of the 'End' key is it works in both normal and insert modes.
'$' works in normal/command mode only but it also works in the classic vi editor (good to know when vim is not available).
The answer above is now obsolete with Unity 5 or newer. Use this instead!
GetComponent<Rigidbody2D>().AddForce(new Vector2(0,10), ForceMode2D.Impulse);
I also want to add that this leaves the jump height super private and only editable in the script, so this is what I did...
public float playerSpeed; //allows us to be able to change speed in Unity
public Vector2 jumpHeight;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update ()
{
transform.Translate(playerSpeed * Time.deltaTime, 0f, 0f); //makes player run
if (Input.GetMouseButtonDown(0) || Input.GetKeyDown(KeyCode.Space)) //makes player jump
{
GetComponent<Rigidbody2D>().AddForce(jumpHeight, ForceMode2D.Impulse);
This makes it to where you can edit the jump height in Unity itself without having to go back to the script.
Side note - I wanted to comment on the answer above, but I can't because I'm new here. :)
Base-64 encoding is a way of taking binary data and turning it into text so that it's more easily transmitted in things like e-mail and HTML form data.
I am using CouchDB in production. Currently it stores all those 'optional' fields that weren't in the original DB schema. And right now I am thinking about moving all data to CouchDB.
It's quite a risky step, I admit. Firstly, because it's not v1.0 yet. And secondly, because it is drivespace-hungry. By my calculations, CouchDB file (with indexes) is ~30 times larger than MySQL database with the same rows. But I am pretty sure it will work out just fine.
If you have a UTF-8 string, where every byte is correct ('Ö' -> [195, 0] , [150, 0]), you can use the following:
public static string Utf8ToUtf16(string utf8String)
{
/***************************************************************
* Every .NET string will store text with the UTF-16 encoding, *
* known as Encoding.Unicode. Other encodings may exist as *
* Byte-Array or incorrectly stored with the UTF-16 encoding. *
* *
* UTF-8 = 1 bytes per char *
* ["100" for the ansi 'd'] *
* ["206" and "186" for the russian '?'] *
* *
* UTF-16 = 2 bytes per char *
* ["100, 0" for the ansi 'd'] *
* ["186, 3" for the russian '?'] *
* *
* UTF-8 inside UTF-16 *
* ["100, 0" for the ansi 'd'] *
* ["206, 0" and "186, 0" for the russian '?'] *
* *
* First we need to get the UTF-8 Byte-Array and remove all *
* 0 byte (binary 0) while doing so. *
* *
* Binary 0 means end of string on UTF-8 encoding while on *
* UTF-16 one binary 0 does not end the string. Only if there *
* are 2 binary 0, than the UTF-16 encoding will end the *
* string. Because of .NET we don't have to handle this. *
* *
* After removing binary 0 and receiving the Byte-Array, we *
* can use the UTF-8 encoding to string method now to get a *
* UTF-16 string. *
* *
***************************************************************/
// Get UTF-8 bytes and remove binary 0 bytes (filler)
List<byte> utf8Bytes = new List<byte>(utf8String.Length);
foreach (byte utf8Byte in utf8String)
{
// Remove binary 0 bytes (filler)
if (utf8Byte > 0) {
utf8Bytes.Add(utf8Byte);
}
}
// Convert UTF-8 bytes to UTF-16 string
return Encoding.UTF8.GetString(utf8Bytes.ToArray());
}
In my case the DLL result is a UTF-8 string too, but unfortunately the UTF-8 string is interpreted with UTF-16 encoding ('Ö' -> [195, 0], [19, 32]). So the ANSI '–' which is 150 was converted to the UTF-16 '–' which is 8211. If you have this case too, you can use the following instead:
public static string Utf8ToUtf16(string utf8String)
{
// Get UTF-8 bytes by reading each byte with ANSI encoding
byte[] utf8Bytes = Encoding.Default.GetBytes(utf8String);
// Convert UTF-8 bytes to UTF-16 bytes
byte[] utf16Bytes = Encoding.Convert(Encoding.UTF8, Encoding.Unicode, utf8Bytes);
// Return UTF-16 bytes as UTF-16 string
return Encoding.Unicode.GetString(utf16Bytes);
}
Or the Native-Method:
[DllImport("kernel32.dll")]
private static extern Int32 MultiByteToWideChar(UInt32 CodePage, UInt32 dwFlags, [MarshalAs(UnmanagedType.LPStr)] String lpMultiByteStr, Int32 cbMultiByte, [Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder lpWideCharStr, Int32 cchWideChar);
public static string Utf8ToUtf16(string utf8String)
{
Int32 iNewDataLen = MultiByteToWideChar(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf8String, -1, null, 0);
if (iNewDataLen > 1)
{
StringBuilder utf16String = new StringBuilder(iNewDataLen);
MultiByteToWideChar(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf8String, -1, utf16String, utf16String.Capacity);
return utf16String.ToString();
}
else
{
return String.Empty;
}
}
If you need it the other way around, see Utf16ToUtf8. Hope I could be of help.

Now it's also possible to reset the database through their web interface.
Go to dashboard.heroku.com select your app and then you'll find the database under the add-ons category, click on it and then you can reset the database.
You have to configure SMTP on your server. You can use G Suite SMTP by Google for free:
<?php
$mail = new PHPMailer(true);
// Send mail using Gmail
if($send_using_gmail){
$mail->IsSMTP(); // telling the class to use SMTP
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "ssl"; // sets the prefix to the servier
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = 465; // set the SMTP port for the GMAIL server
$mail->Username = "[email protected]"; // GMAIL username
$mail->Password = "your-gmail-password"; // GMAIL password
}
// Typical mail data
$mail->AddAddress($email, $name);
$mail->SetFrom($email_from, $name_from);
$mail->Subject = "My Subject";
$mail->Body = "Mail contents";
try{
$mail->Send();
echo "Success!";
} catch(Exception $e){
// Something went bad
echo "Fail :(";
}
?>

I tried using phyatt's AspectRatioPixmapLabel
class, but experienced a few problems:
QLabel::setPixmap(...)
inside the resizeEvent method, because QLabel
actually calls updateGeometry
inside setPixmap
, which may trigger resize events...heightForWidth
seemed to be ignored by the containing widget (a QScrollArea
in my case) until I started setting a size policy for the label, explicitly calling policy.setHeightForWidth(true)
QLabel
's implementation of minimumSizeHint()
does some magic for labels containing text, but always resets the size policy to the default one, so I had to overwrite itThat said, here is my solution. I found that I could just use setScaledContents(true)
and let QLabel
handle the resizing.
Of course, this depends on the containing widget / layout honoring the heightForWidth
.
aspectratiopixmaplabel.h
#ifndef ASPECTRATIOPIXMAPLABEL_H
#define ASPECTRATIOPIXMAPLABEL_H
#include <QLabel>
#include <QPixmap>
class AspectRatioPixmapLabel : public QLabel
{
Q_OBJECT
public:
explicit AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent = 0);
virtual int heightForWidth(int width) const;
virtual bool hasHeightForWidth() { return true; }
virtual QSize sizeHint() const { return pixmap()->size(); }
virtual QSize minimumSizeHint() const { return QSize(0, 0); }
};
#endif // ASPECTRATIOPIXMAPLABEL_H
aspectratiopixmaplabel.cpp
#include "aspectratiopixmaplabel.h"
AspectRatioPixmapLabel::AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent) :
QLabel(parent)
{
QLabel::setPixmap(pixmap);
setScaledContents(true);
QSizePolicy policy(QSizePolicy::Maximum, QSizePolicy::Maximum);
policy.setHeightForWidth(true);
this->setSizePolicy(policy);
}
int AspectRatioPixmapLabel::heightForWidth(int width) const
{
if (width > pixmap()->width()) {
return pixmap()->height();
} else {
return ((qreal)pixmap()->height()*width)/pixmap()->width();
}
}
Alternatively, you can use numpy underlying function:
>>> import numpy as np
>>> df = pd.DataFrame({"A": [10,20,30], "B": [20, 30, 10]})
>>> df['new_column'] = np.multiply(df['A'], df['B'])
>>> df
A B new_column
0 10 20 200
1 20 30 600
2 30 10 300
or vectorize arbitrary function in general case:
>>> def fx(x, y):
... return x*y
...
>>> df['new_column'] = np.vectorize(fx)(df['A'], df['B'])
>>> df
A B new_column
0 10 20 200
1 20 30 600
2 30 10 300
I had the same problem, even the gradle build ran for 8 hours and i was worried. But later on i changed the compile sdk version and minimum sdk version in build.gradle file like this.
Older:
android {
compileSdkVersion 25
buildToolsVersion "29.0.2"
defaultConfig {
applicationId "com.uwebtechnology.salahadmin"
minSdkVersion 9
targetSdkVersion 25
}
New (Updated):
android
{
compileSdkVersion 28
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.uwebtechnology.salahadmin"
minSdkVersion 15
targetSdkVersion 28
}
Floating Point Exception happens because of an unexpected infinity or NaN. You can track that using gdb, which allows you to see what is going on inside your C program while it runs. For more details: https://www.cs.swarthmore.edu/~newhall/unixhelp/howto_gdb.php
In a nutshell, these commands might be useful...
gcc -g myprog.c

Here is a way to detect Zombie transaction
SqlTransaction trans = connection.BeginTransaction();
//some db calls here
if (trans.Connection != null) //Detecting zombie transaction
{
trans.Commit();
}
Decompiling the SqlTransaction class, you will see the following
public SqlConnection Connection
{
get
{
if (this.IsZombied)
return (SqlConnection) null;
return this._connection;
}
}
I notice if the connection is closed, the transOP will become zombie, thus cannot Commit
.
For my case, it is because I have the Commit()
inside a finally
block, while the connection was in the try
block. This arrangement is causing the connection to be disposed and garbage collected. The solution was to put Commit
inside the try
block instead.
PHP - curl:
$username = 'myusername';
$password = 'mypassword';
...
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
...
PHP - POST in WordPress:
$username = 'myusername';
$password = 'mypassword';
...
wp_remote_post('https://...some...api...endpoint...', array(
'headers' => array(
'Authorization' => 'Basic ' . base64_encode("$username:$password")
)
));

If you want to add the id manually you can use,
PadLeft() or String.Format() method.
string id;
char x='0';
id=id.PadLeft(6, x);
//Six character string id with left 0s e.g 000012
int id;
id=String.Format("{0:000000}",id);
//Integer length of 6 with the id. e.g 000012
Then you can append this with UID.
use labelpad parameter:
pl.xlabel("...", labelpad=20)
or set it after:
ax.xaxis.labelpad = 20
chmod 777 <directory>
This will give you execute/read/write privileges. You can play with the numbers to finely tune your desired permissions.

Basically one needs to create a custom background for a spinner. It should be something like this:
spinner_background.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
<color
android:color="@android:color/white"/>
</item>
<item>
<bitmap
android:gravity="center_vertical|right"
android:src="@drawable/ic_arrow_drop_down_black_24dp"/>
</item>
</layer-list>
</item>
</selector>
Then create a custom style for your spinner, where you specify the above selector as background:
<style name="Widget.App.Spinner" parent="@style/Widget.AppCompat.Spinner">
<item name="overlapAnchor">true</item>
<item name="android:background">@drawable/spinner_background</item>
</style>
And finally in your app theme you should override two attributes if you want it to be applied all across your app:
<item name="spinnerStyle">@style/Widget.App.Spinner</item>
<item name="android:spinnerStyle">@style/Widget.App.Spinner</item>
And that's pretty much it.

defines a cluster that you can proxy requests to. It's commonly used for defining either a web server cluster for load balancing, or an app server cluster for routing / load balancing.
If you are seraching for whole words you can do this that works case insensitive.
private boolean containsKeyword(String line, String[] keywords)
{
String[] inputWords = line.split(" ");
for (String inputWord : inputWords)
{
for (String keyword : keywords)
{
if (inputWord.equalsIgnoreCase(keyword))
{
return true;
}
}
}
return false;
}
On Linux (and probably most Unix), there is no OS-level DNS caching unless nscd is installed and running. Even then, the DNS caching feature of nscd is disabled by default at least in Debian because it's broken. The practical upshot is that your linux system very very probably does not do any OS-level DNS caching.
You could implement your own cache in your application (like they did for Squid, according to diegows's comment), but I would recommend against it. It's a lot of work, it's easy to get it wrong (nscd got it wrong!!!), it likely won't be as easily tunable as a dedicated DNS cache, and it duplicates functionality that already exists outside your application.
If an end user using your software needs to have DNS caching because the DNS query load is large enough to be a problem or the RTT to the external DNS server is long enough to be a problem, they can install a caching DNS server such as Unbound on the same machine as your application, configured to cache responses and forward misses to the regular DNS resolvers.
well, this using lodash or vanilla javascript it depends on the situation.
but for just return the array that contains the duplicates it can be achieved by the following, offcourse it was taken from @1983
var result = result1.filter(function (o1) {
return result2.some(function (o2) {
return o1.id === o2.id; // return the ones with equal id
});
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));
I prefers using Guava :
import com.google.common.base.Charsets;
import com.google.common.io.Files;
File file = new File("/path/to/file", Charsets.UTF_8);
String content = Files.toString(file);
I use
chartRange = xlWorkSheet.Rows[1];
chartRange.Font.Bold = true;
to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.
You can call in VBA directly
ActiveCell.Font.Bold = True
With this code I create a timestamp in the active cell, with bold font and yellow background
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
ActiveCell.Value = Now()
ActiveCell.Font.Bold = True
ActiveCell.Interior.ColorIndex = 6
End Sub
Just for completeness (because nobody else posted the most obvious answer):
Oracle:
DECODE(PC_SL_LDGR_CODE, '02', 'DR', 'CR')
MSSQL (2012+):
IIF(PC_SL_LDGR_CODE='02', 'DR', 'CR')
The bad news:
DECODE
with more than 4 arguments would result in an ugly IIF
cascade
You can use +
if you know all the values are strings. Jinja also provides the ~
operator, which will ensure all values are converted to string first.

A little late, but I came up with this. It gives you just the keys and then you can use those on the dynamic:
public List<string> GetPropertyKeysForDynamic(dynamic dynamicToGetPropertiesFor)
{
JObject attributesAsJObject = dynamicToGetPropertiesFor;
Dictionary<string, object> values = attributesAsJObject.ToObject<Dictionary<string, object>>();
List<string> toReturn = new List<string>();
foreach (string key in values.Keys)
{
toReturn.Add(key);
}
return toReturn;
}
Then you simply foreach like this:
foreach(string propertyName in GetPropertyKeysForDynamic(dynamicToGetPropertiesFor))
{
dynamic/object/string propertyValue = dynamicToGetPropertiesFor[propertyName];
// And
dynamicToGetPropertiesFor[propertyName] = "Your Value"; // Or an object value
}
Choosing to get the value as a string or some other object, or do another dynamic and use the lookup again.
Are you looking for the syntax to open them:
Dim wkbk As Workbook
Set wkbk = Workbooks.Open("C:\MyDirectory\mysheet.xlsx")
Then, you can use wkbk.Sheets(1).Range("3:3")
(or whatever you need)
This is what I did to get iframe scrolling to work on iPad. Note that this solution only works if you control the html that is displayed inside the iframe.
It actually turns off the default iframe scrolling, and instead causes the body tag inside the iframe to scroll.
main.html:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
#container {
position: absolute;
top: 50px;
left: 50px;
width: 400px;
height: 300px;
overflow: hidden;
}
#iframe {
width: 400px;
height: 300px;
}
</style>
</head>
<body>
<div id="container">
<iframe src="test.html" id="iframe" scrolling="no"></iframe>
</div>
</body>
</html>
test.html:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
html {
overflow: auto;
-webkit-overflow-scrolling: touch;
}
body {
height: 100%;
overflow: auto;
-webkit-overflow-scrolling: touch;
margin: 0;
padding: 8px;
}
</style>
</head>
<body>
…
</body>
</html>
The same could probably be accomplished using jQuery if you prefer:
$("#iframe").contents().find("body").css({
"height": "100%",
"overflow": "auto",
"-webkit-overflow-scrolling": "touch"
});
I used this solution to get TinyMCE (wordpress editor) to scroll properly on the iPad.
to build on stu's answer. here's how i found the frame rate for a video from my mobile phone. i ran the following command for a while. i let the frame count get up to about ~ 10,000 before i got impatient and hit ^C:
$ ffmpeg -i 2013-07-07\ 12.00.59.mp4 -f null /dev/null 2>&1
...
Press [q] to stop, [?] for help
[null @ 0x7fcc80836000] Encoder did not produce proper pts, making some up.

$
then, i grabbed two pieces of information from that line which starts with "frame=", the frame count, 7989, and the time, 00:04:26.30. You first need to convert the time into seconds and then divide the number of frames by seconds to get "frames per second". "frames per second" is your frame rate.
$ bc -l

266.3

the framerate for my video is 30 fps.
Just stumbled upon this and thought I would suggest my solution. I typically like to use the built in functionality of assigning a range to an multi-dim array (I guess it's also the JS Programmer in me).
I frequently write code like this:
Sub arrayBuilder()
myarray = Range("A1:D4")
'unlike most VBA Arrays, this array doesn't need to be declared and will be automatically dimensioned
For i = 1 To UBound(myarray)
For j = 1 To UBound(myarray, 2)
Debug.Print (myarray(i, j))
Next j
Next i
End Sub
Assigning ranges to variables is a very powerful way to manipulate data in VBA.
Internet Explorer’s Ajax Caching: What Are YOU Going To Do About It? suggests three approaches:
- Add a cache busting token to the query string, like ?date=[timestamp]. In jQuery and YUI you can tell them to do this automatically.
- Use POST instead of a GET
- Send a HTTP response header that specifically forbids browsers to cache it
or programmaticaly
String s = String.class.getName();
s = s.substring(s.lastIndexOf('.') + 1);
If the string is Unicode the easiest way is:
import base64
a = base64.b64encode(bytes(u'complex string: ñáéíóúÑ', "utf-8"))
# a: b'Y29tcGxleCBzdHJpbmc6IMOxw6HDqcOtw7PDusOR'
b = base64.b64decode(a).decode("utf-8", "ignore")
print(b)
# b :complex string: ñáéíóúÑ
The accepted answer no longer works. When running the command xcode-select --install
it tells you to use "Software Update" to install updates.
In this link is the updated method:
Open a Terminal and then:
cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg
This will open an installation Wizard.
After updating to Mojave 10.15.1 it seems that using xcode-select --install
works as intended.
tray this:
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_close);
inside onCreate()
;
Please check that your key exists in the array or not, instead of simply trying to access it.
Replace:
$myVar = $someArray['someKey']
With something like:
if (isset($someArray['someKey'])) {
$myVar = $someArray['someKey']
}
or something like:
if(is_array($someArray['someKey'])) {
$theme_img = 'recent_works_iso_thumbnail';
}else {
$theme_img = 'recent_works_iso_thumbnail';

I know this is a bit old, but in case another beginner is going through this, I'll share some code that covers a bit more of the basic operations, here is another example that also includes the option to cancel the process and also report to the user the status of the process. I'm going to add on top of the code given by Alex Aza in the solution above
public Form1()
{
InitializeComponent();
backgroundWorker1.DoWork += backgroundWorker1_DoWork;
backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
backgroundWorker1.RunWorkerCompleted += backgroundWorker1_RunWorkerCompleted; //Tell the user how the process went
backgroundWorker1.WorkerReportsProgress = true;
backgroundWorker1.WorkerSupportsCancellation = true; //Allow for the process to be cancelled
}
//Start Process
private void button1_Click(object sender, EventArgs e)
{
backgroundWorker1.RunWorkerAsync();
}
//Cancel Process
private void button2_Click(object sender, EventArgs e)
{
//Check if background worker is doing anything and send a cancellation if it is
if (backgroundWorker1.IsBusy)
{
backgroundWorker1.CancelAsync();
}
}
private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
for (int i = 0; i < 100; i++)
{
Thread.Sleep(1000);
backgroundWorker1.ReportProgress(i);
//Check if there is a request to cancel the process
if (backgroundWorker1.CancellationPending)
{
e.Cancel = true;
backgroundWorker1.ReportProgress(0);
return;
}
}
//If the process exits the loop, ensure that progress is set to 100%
//Remember in the loop we set i < 100 so in theory the process will complete at 99%
backgroundWorker1.ReportProgress(100);
}
private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
progressBar1.Value = e.ProgressPercentage;
}
private void backgroundWorker1_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
if (e.Cancelled)
{
lblStatus.Text = "Process was cancelled";
}

Here's a non-standard but cross-browser method that may be useful if you don't want to pass any arguments:-
Html:
<div onclick=myHandler() id="my element's id">→ Click Here! ←</div>
Script:
function myHandler(){
alert(myHandler.caller.arguments[0].target.id)
}
None of the above answers worked for me. I kept getting this error:
Copy-Item : Access is denied
+ CategoryInfo : PermissionDenied: (\\192.168.1.100\Shared\test.txt:String) [Copy-Item], UnauthorizedAccessException>
+ FullyQualifiedErrorId : ItemExistsUnauthorizedAccessError,Microsoft.PowerShell.Commands.CopyItemCommand
So this did it for me:
netsh advfirewall firewall set rule group="File and Printer Sharing" new enable=yes
Then from my host my machine in the Run box I just did this:
\\{IP address of nanoserver}\C$
You could use CSS for this and create classes for the elements. So you'd have something like this
p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
Then your HTML would read:
<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
It's a lot neater then inline stylesheets, is easier to maintain and provides greater reuse.
Here's the complete HTML to demonstrate what I mean:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<style type="text/css">
p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
</style>
</head>
<body>
<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
</body>
</html>
You'll see that I have the stylesheet classes in a style tag in the header, and then I only apply those classes in the code such as <p class="detail"> ... </p>
. Go through the w3schools tutorial, it will only take a couple of hours and will really turn you around when it comes to styling your HTML elements. If you cut and paste that into an HTML document you can edit the styles and see what effect they have when you open the file in a browser. Experimenting like this is a great way to learn.
To add a new file in SVN
svn add file_name
svn commit -m "text about changes..."
To add a new file in a directory in SVN
svn add directory_name/file_name
svn commit -m "text about changes"
To add all new files in a directory with some targets (files) are already versioned (added):
svn add directory_name/*
svn commit -m "text about changes"
I just spent several hours hunting for the answer to a similar but slightly different question - I needed to be able to delete all objects in R (including functions) except a handful of vectors.
One way to do this:
rm(list=ls()[! ls() %in% c("a","c")])
Where the vectors that I want to keep are named 'a' and 'c'.
Hope this helps anyone searching for the same solution!
You should remove navbar-fixed-top
class otherwise navbar stays fixed on top of page where you want logo.
If you want to place logo inside navbar:
Navbar height (set in @navbarHeight
LESS variable) is 40px
by default. Your logo has to fit inside or you have to make navbar higher first.
Then use brand
class:
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<a href="/" class="brand"><img alt="" src="/logo.gif" /></a>
</div>
</div>
</div>
If your logo is higher than 20px
, you have to fix stylesheets as well.
If you do that in LESS:
.navbar .brand {
@elementHeight: 32px;
padding: ((@navbarHeight - @elementHeight) / 2 - 2) 20px ((@navbarHeight - @elementHeight) / 2 + 2);
}
@elementHeight
should be set to your image height.
Padding calculation is taken from Twitter Bootstrap LESS - https://github.com/twitter/bootstrap/blob/v2.0.4/less/navbar.less#L51-52
Alternatively you can calculate padding values yourself and use pure CSS.
This works for Twitter Bootstrap versions 2.0.x, should work in 2.1 as well, but padding calculation was changed a bit: https://github.com/twitter/bootstrap/blob/v2.1.0/less/navbar.less#L50
Have you tried with the custom format "#,##0.##"
?
I have the same problem with angular 6, that's what worked for me :
@NgModule({
...
entryComponents: [ConfirmComponent],
providers:[ConfirmService]
})
If you have a service like ConfirmService, have to be declare in providers of current module instead of root
This is the behavior of ln
if the second arg is a directory. It places a link to the first arg inside it. If you want /etc/nginx
to be the symlink, you should remove that directory first and run that same command.
I think you're getting confused about what can hold what in JSON.Net.
JToken
is a generic representation of a JSON value of any kind. It could be a string, object, array, property, etc.JProperty
is a single JToken
value paired with a name. It can only be added to a JObject
, and its value cannot be another JProperty
.JObject
is a collection of JProperties
. It cannot hold any other kind of JToken
directly.In your code, you are attempting to add a JObject
(the one containing the "banana" data) to a JProperty
("orange") which already has a value (a JObject
containing {"colour":"orange","size":"large"}
). As you saw, this will result in an error.
What you really want to do is add a JProperty
called "banana" to the JObject
which contains the other fruit JProperties
. Here is the revised code:
JObject foodJsonObj = JObject.Parse(jsonText);
JObject fruits = foodJsonObj["food"]["fruit"] as JObject;
fruits.Add("banana", JObject.Parse(@"{""colour"":""yellow"",""size"":""medium""}"));
To remove an app from the App Store, deselect all territories in your app's Rights and Pricing section on the App Summary page accessible from the Manage Your Applications module. Your app status will change to Developer Removed from Sale and will be removed from the App Store until you make it available again using the Rights and Pricing section.
I like this short video here mesos learning material
with bare metal clusters, you would need to spawn stacks like HDFS, SPARK, MR etc... so if you launch tasks related to these using only bare metal cluster management, there will be a lot cold starting time.
with mesos, you can install these services on top of the bare metals and you can avoid the bring up time of those base services. This is something mesos does well. and can be utilised by kubernetes building on top of it.
IE10 has uses the old syntax. So:
display: -ms-flexbox; /* will work on IE10 */
display: flex; /* is new syntax, will not work on IE10 */
see css-tricks.com/snippets/css/a-guide-to-flexbox:
(tweener) means an odd unofficial syntax from [2012] (e.g. display: flexbox;)
For MySQL:
SELECT contract, activity
FROM table
GROUP BY contract
HAVING COUNT(DISTINCT activity) = 1
I encountered the same issue and was not at all sure how to resolve it. Yes this occurs because an exception is being thrown from the service, but there are a few general guidelines that you can follow to correct this:
ServiceBase[] ServicesToRun;
ServicesToRun = new ServiceBase[]
{
new WinsowsServiceToRun()
};
ServiceBase.Run(ServicesToRun);
You need to ensure that there is some kind of infinite loop running in the class WinsowsServiceToRun
Finally, there may be some code which is not logging anything and closing the program abruptly (which was the case with me), in this case you will have to follow the old school of debugging which needed to write a line to a source (text/db/wherever). What I faced was that since the account running the service was not "Admin", the code was just falling off and not logging any exceptions in case it was trying to write to "Windows Event Log" even though the code was there to log exceptions. Admin privilege is actually not needed for logging to Even Log but it is needed to define the source. In case source of the event is not already defined in the system and the service tries to log it for the first time without admin privilege it fails. To solve this follow below steps:
eventcreate /ID 1 /L APPLICATION /T INFORMATION /SO <<Source>> /D "<<SourceUsingWhichToWrite>>"
To answer your first question: yes it is feasible to develop an android application in pure python, in order to achieve this I suggest you use BeeWare, which is just a suite of python tools, that work together very well and they enable you to develop platform native applications in python.
checkout this video by the creator of BeeWare that perfectly explains and demonstrates it's application
Android's preferred language of implementation is Java - so if you want to write an Android application in Python, you need to have a way to run your Python code on a Java Virtual Machine. This is what VOC does. VOC is a transpiler - it takes Python source code, compiles it to CPython Bytecode, and then transpiles that bytecode into Java-compatible bytecode. The end result is that your Python source code files are compiled directly to a Java .class file, which can be packaged into an Android application.
VOC also allows you to access native Java objects as if they were Python objects, implement Java interfaces with Python classes, and subclass Java classes with Python classes. Using this, you can write an Android application directly against the native Android APIs.
Once you've written your native Android application, you can use Briefcase to package your Python code as an Android application.
Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:
You can check This native Android Tic Tac Toe app written in Python, using the BeeWare suite. on GitHub
in addition to the BeeWare tools, you'll need to have a JDK and Android SDK installed to test run your application.
and to answer your second question: a good environment can be anything you are comfortable with be it a text editor and a command line, or an IDE, if you're looking for a good python IDE I would suggest you try Pycharm, it has a community edition which is free, and it has a similar environment as android studio, due to to the fact that were made by the same company.
I hope this has been helpful
If it concerns just one (or a few) specific vars you want to change, I think the easiest way is a workaround: just set in in your environment AND in your current console session
I have this simple batch script to change my Maven from Java7 to Java8 (which are both env. vars) The batch-folder is in my PATH var so I can always call 'j8' and within my console and in the environment my JAVA_HOME var gets changed:
j8.bat:
@echo off
set JAVA_HOME=%JAVA_HOME_8%
setx JAVA_HOME "%JAVA_HOME_8%"
Till now I find this working best and easiest. You probably want this to be in one command, but it simply isn't there in Windows...
If think you are looking for something like this.
public static char toUnsigned(byte b) {
return (char) (b >= 0 ? b : 256 + b);
}
Margin
is returning a struct, which means that you are editing a copy. You will need something like:
var margin = MyControl.Margin;
margin.Left = 10;
MyControl.Margin = margin;
In some circumstances it might be useful to simply remove the bindings and then re-apply:
ko.cleanNode(document.getElementById(element_id))
ko.applyBindings(viewModel, document.getElementById(element_id))
Try PySoundCard which uses PortAudio for playback which is available on many platforms. In addition, it recognizes "professional" sound devices with lots of channels.
Here a small example from the Readme:
from pysoundcard import Stream
"""Loop back five seconds of audio data."""
fs = 44100
blocksize = 16
s = Stream(samplerate=fs, blocksize=blocksize)
s.start()
for n in range(int(fs*5/blocksize)):
s.write(s.read(blocksize))
s.stop()
I have figured out how this is done for Sony devices.
I've blogged about it here. I've also posted a seperate SO question about this here.
Sony devices use a class named BadgeReciever
.
Declare the com.sonyericsson.home.permission.BROADCAST_BADGE
permission in your manifest file:
Broadcast an Intent
to the BadgeReceiver
:
Intent intent = new Intent();
intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
sendBroadcast(intent);
Done. Once this Intent
is broadcast the launcher should show a badge on your application icon.
To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE
set to false:
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.
A DataFrame follows the dict-like convention of iterating over the “keys” of the objects.
my_dataframe.keys()
Create a list of keys/columns - object method to_list()
and pythonic way
my_dataframe.keys().to_list()
list(my_dataframe.keys())
Basic iteration on a DataFrame returns column labels
[column for column in my_dataframe]
Do not convert a DataFrame into a list, just to get the column labels. Do not stop thinking while looking for convenient code samples.
xlarge = pd.DataFrame(np.arange(100000000).reshape(10000,10000))
list(xlarge) #compute time and memory consumption depend on dataframe size - O(N)
list(xlarge.keys()) #constant time operation - O(1)
Wrap the "set" statement to mean "set if not set" and put it naked above the while loop.
You are correct, the language does not provide what you're looking for in exactly that syntax, but that's because there are programming paradigms like the one I just suggested so you don't need the syntax you are proposing.
The problem is that you are using a lower case v.
You need to set it to Value and it should fix your issue:
@Html.TextBoxFor(model => model.Destination, new { id = "txtPlace", Value= "3" })
Try this:
$("div[class]").filter(function() {
var classNames = this.className.split(/\s+/);
for (var i=0; i<classNames.length; ++i) {
if (classNames[i].substr(0, 6) === "apple-") {
return true;
}
}
return false;
})
To add to the other answers in Android, Ems size, can, by default, vary in each language and input.
It means that if you want to set a minimum width to a text field, defined by number of chars, you have to calculate the Ems properly and set it, according to your typeface and font size with the Ems attribute.
To those of you struggle with this, you can calculate the hint size yourself to avoid messing with Ems:
val tf = TextField()
val layout = TextInputLayout()
val hint = "Hint"
val measureText = tf.paint.measureText(hint).toInt()
tf.width = tf.paddingLeft + tf.paddingRight + measureText.toInt()
layout.hint = hint
Apache Commons has an IntegerValidator class which appears to do what you want. Java provides no in-built method for doing this.
See here for the groupid/artifactid.
You can use a lookahead:
/(?=\S)[^\\]/
Change that import to
from matplotlib.pyplot import *
Note that this style of imports (from X import *
) is generally discouraged. I would recommend using the following instead:
import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
return reduce(Math::max);
is NOT EQUAL to return reduce(max());
But it means, something like this:
IntBinaryOperator myLambda = (a, b)->{(a >= b) ? a : b};//56 keystrokes I had to type -_-
return reduce(myLambda);
You can just save 47 keystrokes if you write like this
return reduce(Math::max);//Only 9 keystrokes ^_^
It's an awesome detailed reply by Janusz. But just for the sake of people who are coming to this page for answers, the easier way is at http://android-holo-colors.com/ (dead link) linked from Android Asset Studio
A good description of all the tools are at AndroidOnRocks.com (site offline now)
However, I highly recommend everybody to read the reply from Janusz as it will make understanding clearer. Use the tool to do stuffs real quick
Regarding the original question asked in the title ...
sudo apt-get install libtcnative-1
or if you are on RHEL Linux yum install tomcat-native
The documentation states you need http://tomcat.apache.org/native-doc/

yum install apr-devel openssl-devel
Could it be that you are passing the data through get, not post?
<form method="get" ..>
..
</form>
<div class="foo">Foo Bar</div>
and in your CSS file:
.foo {
background-image: url("images/foo.png");
}
I think you want to print the name of the person or both the name and email :
const renObjData = this.props.data.map(function(data, idx) {
return <p key={idx}>{data.name}</p>;
});
or :
const renObjData = this.props.data.map(function(data, idx) {
return ([
<p key={idx}>{data.name}</p>,
<p key={idx}>{data.email}</p>,
]);
});

; This is an example of how a Python Launcher .ini file is structured.

Yes, you can program Android apps in C++ (for the most part), using the Native Development Kit (NDK), although Java is the primary/preferred language for programming Android, and your C++ code will likely have to interface with Java components, and you'll likely need to read and understand the documentation for Java components, as well. Therefore, I'd advise you to use Java unless you have some existing C++ code base that you need to port and that isn't practical to rewrite in Java.
Java is very similar to C++, I don't think you will have any problems picking it up... going from C++ to Java is incredibly easy; going from Java to C++ is a little more difficult, though not terrible. Java for C++ Programmers does a pretty good job at explaining the differences. Writing your Android code in Java will be more idiomatic and will also make the development process easier for you (as the tooling for the Java Android SDK is significantly better than the corresponding NDK tooling)
In terms of setup, Google provides the Android Studio IDE for both Java and C++ Android development (with Gradle as the build system), but you are free to use whatever IDE or build system you want so long as, under the hood, you are using the Android SDK / NDK to produce the final outputs.
A simple method of creating the service, adding headers and reading the JSON response,
private static void WebRequest()
{
const string WEBSERVICE_URL = "<<Web Service URL>>";
try
{
var webRequest = System.Net.WebRequest.Create(WEBSERVICE_URL);
if (webRequest != null)
{
webRequest.Method = "GET";
webRequest.Timeout = 20000;
webRequest.ContentType = "application/json";
webRequest.Headers.Add("Authorization", "Basic dcmGV25hZFzc3VudDM6cGzdCdvQ=");
using (System.IO.Stream s = webRequest.GetResponse().GetResponseStream())
{
using (System.IO.StreamReader sr = new System.IO.StreamReader(s))
{
var jsonResponse = sr.ReadToEnd();
Console.WriteLine(String.Format("Response: {0}", jsonResponse));
}
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
Here's a solution that works with fixed backgrounds, if you have a fixed background and you have some overlayed elements and you need blured backgrounds for them, this solution works:
Image we have this simple HTML:
<body> <!-- or any wrapper -->
<div class="content">Some Texts</div>
</body>
A fixed background for <body>
or the wrapper element:
body {
background-image: url(http://placeimg.com/640/360/any);
background-size: cover;
background-repeat: no-repeat;
background-attachment: fixed;
}
And here for example we have a overlayed element with a white transparent background:
.content {
background-color: rgba(255, 255, 255, 0.3);
position: relative;
}
Now we need to use the exact same background image of our wrapper for our overlay elements too, i use it as a :before
psuedo-class:
.content:before {
content: '';
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
z-index: -1;
filter: blur(5px);
background-image: url(http://placeimg.com/640/360/any);
background-size: cover;
background-repeat: no-repeat;
background-attachment: fixed;
}
Since the fixed background works in a same way in both wrapper and overlayed elements, we have the background in exactly same scroll position of the overlayed element and we can simply blur it. Here's a working fiddle, tested in Firefox, Chrome, Opera and Edge: https://jsfiddle.net/0vL2rc4d/
NOTE: In firefox there's a bug that makes screen flicker when scrolling and there are fixed blurred backgrounds. if there's any fix, let me know
You are trying to use it as a CSS file, probably by using
<link rel=stylesheet href=ABCD.html>
or
<style>
@import url("ABCD.html");
</style>
Simply put you can't do the following:
class C(object):
def x(self, y, **kwargs):
# Which y to use, kwargs or declaration?
pass
c = C()
y = "Arbitrary value"
kwargs["y"] = "Arbitrary value"
c.x(y, **kwargs) # FAILS
Because you pass the variable 'y' into the function twice: once as kwargs and once as function declaration.
As an addendum, if you are using this technique to define strings in your target, this is how I had to define and use them:
In Build Settings -> Preprocessor Macros, and yes backslashes are critical in the definition:
APPURL_NSString=\@\"www.foobar.org\"
And in the source code:
objectManager.client.baseURL = APPURL_NSString;
EDIT:
Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities
This works on my side :
List<string> materialTypes = (from u in result.Users
select u.LastName)
.Union(from u in result.Users
select SqlFunctions.StringConvert((double) u.UserId)).ToList();
On yours it should be like this:
IList<String> materialTypes = ((from tom in context.MaterialTypes
where tom.IsActive == true
select tom.Name)
.Union(from tom in context.MaterialTypes
where tom.IsActive == true
select SqlFunctions.StringConvert((double)tom.ID))).ToList();
Thanks, i've learnt something today :)
You can use nslookup
on the IP. Reverse DNS is defined with the .in-addr.arpa
domain.
Example:
nslookup somedomain.com
yields 123.21.2.3
, and then you do:
nslookup 123.21.2.3
this will ask 3.2.21.123.in-addr.arpa
and yield the domain name (if there is one defined for reverse DNS).
You did not activate the virtual environment before using pip.
Try it with:
$(your venv path) . bin/activate
And then use pip -r requirements.txt on your main folder
In two ways we can solve this problem:
<div>
element.render() {
return (
<View style={styles.container}>
if (this.state == 'news'){
return (
<Text>data</Text>
);
}
else {
<div> </div>
}
</View>
)
}
I just discovered that MySQL will take null provided the default for the field is null and I write specific if statements and leave off the quotes. This works for update as well.
if(empty($odate) AND empty($ddate))
{
$query2="UPDATE items SET odate=null, ddate=null, istatus='$istatus' WHERE id='$id' ";
};
Check service dependencies if they are disabled.
Set those dependencies to Automatic, Start them and it should work.
Anything using the managed environment (which includes anything written in C# and VB.NET) requires the .NET framework. You can simply redistribute your .EXE in that scenario, but they'll need to install the appropriate framework if they don't already have it.
After having really long discussion with CloudBees guys about properly maven packaging of such kind of JARs, they made an interesting good proposal for a solution:
Creation of a fake Maven project which attaches a pre-existing JAR as a primary artifact, running into belonged POM install:install-file execution. Here is an example of such kinf of POM:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<id>image-util-id</id>
<phase>install</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<file>${basedir}/file-you-want-to-include.jar</file>
<groupId>${project.groupId}</groupId>
<artifactId>${project.artifactId}</artifactId>
<version>${project.version}</version>
<packaging>jar</packaging>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
But in order to implement it, existing project structure should be changed. First, you should have in mind that for each such kind of JAR there should be created different fake Maven project (module). And there should be created a parent Maven project including all sub-modules which are : all JAR wrappers and existing main project. The structure could be :
root project (this contains the parent POM file includes all sub-modules with module XML element) (POM packaging)
JAR 1 wrapper Maven child project (POM packaging)
JAR 2 wrapper Maven child project (POM packaging)
main existing Maven child project (WAR, JAR, EAR .... packaging)
When parent running via mvn:install or mvn:packaging is forced and sub-modules will be executed. That could be concerned as a minus here, since project structure should be changed, but offers a non static solution at the end
If you need the path
and thedomain
for each cookie, which get_dict()
is not exposes, you can parse the cookies manually, for instance:
[
{'name': c.name, 'value': c.value, 'domain': c.domain, 'path': c.path}
for c in session.cookies
]
Yes you can use them, for example I use them to more easily style groups of data, like this:
thead th { width: 100px; border-bottom: solid 1px #ddd; font-weight: bold; }_x000D_
tbody:nth-child(odd) { background: #f5f5f5; border: solid 1px #ddd; }_x000D_
tbody:nth-child(even) { background: #e5e5e5; border: solid 1px #ddd; }
_x000D_
<table>_x000D_
<thead>_x000D_
<tr><th>Customer</th><th>Order</th><th>Month</th></tr>_x000D_

<tbody>_x000D_
<tr><td>Customer 1</td><td>#1</td><td>January</td></tr>_x000D_

You can view an example here. It'll only work in newer browsers, but that's what I'm supporting in my current application, you can use the grouping for JavaScript etc. The main thing is it's a convenient way to visually group the rows to make the data much more readable. There are other uses of course, but as far as applicable examples, this one is the most common one for me.
I think this can be done as follows:
class ColorComparator implements Comparator<CarSort>
{
private List<String> sortOrder;
public ColorComparator (List<String> sortOrder){
this.sortOrder = sortOrder;
}
public int compare(CarSort c1, CarSort c2)
{
String a1 = c1.getColor();
String a2 = c2.getColor();
return sortOrder.indexOf(a1) - sortOrder.indexOf(a2);
}
}
For sorting use this:
Collections.sort(carList, new ColorComparator(sortOrder));
Here the defination of Rendersection from MSDN
In layout pages, renders the content of a named section.MSDN
In _layout.cs page put
@RenderSection("Bottom",false)
Here render the content of bootom section and specifies false
boolean property to specify whether the section is required or not.
@section Bottom{
This message form bottom.
}
That meaning if you want to bottom section in all pages, then you must use false as the second parameter at Rendersection method.
Using Moment, Underscore and jQuery, to iterate an array of dates.
Sample JSON:
"workerList": [{
"shift_start_dttm": "13/06/2017 20:21",
"shift_end_dttm": "13/06/2017 23:59"
}, {
"shift_start_dttm": "03/04/2018 00:00",
"shift_end_dttm": "03/05/2018 00:00"
}]
Javascript:
function getMinStartDttm(workerList) {
if(!_.isEmpty(workerList)) {
var startDtArr = [];
$.each(d.workerList, function(index,value) {
startDtArr.push(moment(value.shift_start_dttm.trim(), 'DD/MM/YYYY HH:mm'));
});
var startDt = _.min(startDtArr);
return start.format('DD/MM/YYYY HH:mm');
} else {
return '';
}
}
Hope it helps.
This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.
<LimitExcept OPTIONS>
AuthType Basic
AuthName <AUTH_NAME>
Require valid-user
AuthUserFile <FILE_PATH>
</LimitExcept>
try this, it works for me.

In the actual file that was complaining.
I am currently using the Google API to retrieve the location that the user enters in the form/ input. I'm also using an angular function that showing the current location and suggests a city name pin code etc...
- add google API index.html.
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=xxxxxxxx&libraries=geometry,places"></script>
- add id in input box to get string & charcters.
<input id="autocomplete" type="text"(keydown)="checkAddress($event.target.value)">
- and create function on your component.ts file.
import these file
import * as _ from 'lodash';
declare var google: any;
checkAddress(value) {
if (!value) {
this.model.location = _.cloneDeep(value);
this.rfpForm.controls['location'].setValue(this.model.location);
}
}
initLocationAutocomplete() {
let autocomplete, place;
const getLocation = () => {
place = autocomplete.getPlace();
if (place && (place.formatted_address || place.name)) {
// if you want set value in your form controls like this
this.model.location = _.cloneDeep(place.formatted_address || place.name);
// YourFormName.controls['location'].setValue(this.model.location);
// YourFormName.controls['location']['_touched'] = true;
}
};
autocomplete = new google.maps.places.Autocomplete((document.getElementById('autocomplete')), { types: ['geocode'] });
autocomplete.addListener('place_changed', getLocation);
}

This is the only solution that works reliably when adding/subtracting across months and years. Realized this after spending way too much time mucking around with the getDate and setDate methods, trying to adjust for month/year shifts.
decasteljau (in this thread) has already answered this but just want to emphasize the utility of this method because 90% of the answers out there recommend the getDate and setDate approach.
Another way (currently showing 25MB free on my G1):

With respect to the String class:
The equals() method compares the "value" inside String instances (on the heap) irrespective if the two object references refer to the same String instance or not. If any two object references of type String refer to the same String instance then great! If the two object references refer to two different String instances .. it doesn't make a difference. Its the "value" (that is: the contents of the character array) inside each String instance that is being compared.
On the other hand, the "==" operator compares the value of two object references to see whether they refer to the same String instance. If the value of both object references "refer to" the same String instance then the result of the boolean expression would be "true"..duh. If, on the other hand, the value of both object references "refer to" different String instances (even though both String instances have identical "values", that is, the contents of the character arrays of each String instance are the same) the result of the boolean expression would be "false".
As with any explanation, let it sink in.
I hope this clears things up a bit.

You want the list items to line up next to each other, but not really be inline elements. So float them instead:
ol.widgets li {
float: left;
margin-left: 10px;
}
IN bootstrap 4 you need to add popper js for tooltip, I also don`t understand why bootstrap 4 includes external popper.js, It means bootstrap makes more complicated instead of easy when upgrading to the latest versions.
You can import popper js before bootstrap on angular or a simple html, Angular import would be like this
npm install popper.js --save
then go to .angular-cli.json and change the order like below.
"scripts": [
"../node_modules/jquery/dist/jquery.slim.min.js",
"../node_modules/tether/dist/js/tether.min.js",
"../node_modules/popper.js/dist/umd/popper.js",
"../node_modules/bootstrap/dist/js/bootstrap.min.js"
],
you can also use CDN direct call popper js into your any project.
https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.5/umd/popper.js https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.5/umd/popper.min.js

Using <table> is not a bad choice. Of course it is bit old fashioned.
But still not obsolete. But if you prefer you can use "Boostrap". There you have options for panels and enhanced forms.
This is the sample code for your requirement. Used minimal styles to simplify.
<!DOCTYPE html>
<html>
<head>
<title>Simple Login Form</title>
</head>
<style>
table{
border-style: solid;
position: absolute;
top: 40%;
left : 40%;
padding:10px;
}
</style>

If you are using Minikube, there is a magic command!

The good news is a transaction in SQL Server can span multiple batches (each exec
is treated as a separate batch.)
You can wrap your EXEC
statements in a BEGIN TRANSACTION
and COMMIT
but you'll need to go a step further and rollback if any errors occur.
Ideally you'd want something like this:
BEGIN TRY
BEGIN TRANSACTION
exec( @sqlHeader)
exec(@sqlTotals)
exec(@sqlLine)
COMMIT
END TRY
BEGIN CATCH
IF @@TRANCOUNT > 0
ROLLBACK
END CATCH
The BEGIN TRANSACTION
and COMMIT
I believe you are already familiar with. The BEGIN TRY
and BEGIN CATCH
blocks are basically there to catch and handle any errors that occur. If any of your EXEC
statements raise an error, the code execution will jump to the CATCH
block.
Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.
Your .eslintrc.json should contain the text below.
This way ESLint knows about your global variables.
{
"env": {
"browser": true,
"node": true
}
}
This solution requires you to add a second ListBox element and place it above the first one.
Like this:
Then you call the function CreateListBoxHeader to make the alignment correct and add header items.
Result:
Public Sub CreateListBoxHeader(body As MSForms.ListBox, header As MSForms.ListBox, arrHeaders)
' make column count match
header.ColumnCount = body.ColumnCount
header.ColumnWidths = body.ColumnWidths
' add header elements
header.Clear
header.AddItem
Dim i As Integer
For i = 0 To UBound(arrHeaders)
header.List(0, i) = arrHeaders(i)
Next i
' make it pretty
body.ZOrder (1)
header.ZOrder (0)
header.SpecialEffect = fmSpecialEffectFlat
header.BackColor = RGB(200, 200, 200)
header.Height = 10
' align header to body (should be done last!)
header.Width = body.Width
header.Left = body.Left
header.Top = body.Top - (header.Height - 1)
End Sub
Private Sub UserForm_Activate()
Call CreateListBoxHeader(Me.listBox_Body, Me.listBox_Header, Array("Header 1", "Header 2"))
End Sub
string s = @"$KUH% I*$)OFNlkfn$";
var withoutSpecial = new string(s.Where(c => Char.IsLetterOrDigit(c)
|| Char.IsWhiteSpace(c)).ToArray());
if (s != withoutSpecial)
{
Console.WriteLine("String contains special chars");
}
if you happened to use NLog in your ASP.net project, you can add a Debugger target:
<targets>
<target name="debugger" xsi:type="Debugger"
layout="${date:format=HH\:mm\:ss}|${pad:padding=5:inner=${level:uppercase=true}}|${message} "/>
and writes logs to this target for the levels you want:
<rules>
<logger name="*" minlevel="Trace" writeTo="debugger" />
now you have console output just like Jetty in "Output" window of VS, and make sure you are running in Debug Mode(F5).
>>>Set = ["A", "B","C","D"]
>>>n = 2
>>>Subsets=[[i for i,s in zip(Set, status) if int(s) ] for status in [(format(bit,'b').zfill(len(Set))) for bit in range(2**len(Set))] if sum(map(int,status)) == n]
>>>Subsets
[['C', 'D'], ['B', 'D'], ['B', 'C'], ['A', 'D'], ['A', 'C'], ['A', 'B']]
You need to decode data from input string into unicode, before using it, to avoid encoding problems.
field.text = data.decode("utf8")
If someone else keeps getting the same error. Just add one extra div in your component template.
As the documentation says:
Component template should contain exactly one root element
Check this simple example:
import yourComponent from '{path to component}'
export default {
components: {
yourComponent
},
}
// Child component
<template>
<div> This is the one! </div>
</template>
You're not actually going out after the values. You would need to gather them like this:
var title = document.getElementById("title").value;
var name = document.getElementById("name").value;
var tickets = document.getElementById("tickets").value;
You could put all of these in one array:
var myArray = [ title, name, tickets ];
Or many arrays:
var titleArr = [ title ];
var nameArr = [ name ];
var ticketsArr = [ tickets ];
Or, if the arrays already exist, you can use their .push()
method to push new values onto it:
var titleArr = [];
function addTitle ( title ) {
titleArr.push( title );
console.log( "Titles: " + titleArr.join(", ") );
}
Your save button doesn't work because you refer to this.form
, however you don't have a form on the page. In order for this to work you would need to have <form>
tags wrapping your fields:
I've made several corrections, and placed the changes on jsbin: http://jsbin.com/ufanep/2/edit
The new form follows:
<form>
<h1>Please enter data</h1>
<input id="title" type="text" />
<input id="name" type="text" />
<input id="tickets" type="text" />
<input type="button" value="Save" onclick="insert()" />
<input type="button" value="Show data" onclick="show()" />
</form>
<div id="display"></div>
There is still some room for improvement, such as removing the onclick
attributes (those bindings should be done via JavaScript, but that's beyond the scope of this question).
I've also made some changes to your JavaScript. I start by creating three empty arrays:
var titles = [];
var names = [];
var tickets = [];
Now that we have these, we'll need references to our input fields.
var titleInput = document.getElementById("title");
var nameInput = document.getElementById("name");
var ticketInput = document.getElementById("tickets");
I'm also getting a reference to our message display box.
var messageBox = document.getElementById("display");
The insert()
function uses the references to each input field to get their value. It then uses the push()
method on the respective arrays to put the current value into the array.
Once it's done, it cals the clearAndShow()
function which is responsible for clearing these fields (making them ready for the next round of input), and showing the combined results of the three arrays.
function insert ( ) {
titles.push( titleInput.value );
names.push( nameInput.value );
tickets.push( ticketInput.value );
clearAndShow();
}
This function, as previously stated, starts by setting the .value
property of each input to an empty string. It then clears out the .innerHTML
of our message box. Lastly, it calls the join()
method on all of our arrays to convert their values into a comma-separated list of values. This resulting string is then passed into the message box.
function clearAndShow () {
titleInput.value = "";
nameInput.value = "";
ticketInput.value = "";
messageBox.innerHTML = "";
messageBox.innerHTML += "Titles: " + titles.join(", ") + "<br/>";
messageBox.innerHTML += "Names: " + names.join(", ") + "<br/>";
messageBox.innerHTML += "Tickets: " + tickets.join(", ");
}
The final result can be used online at http://jsbin.com/ufanep/2/edit

To remove all spaces in every column, you can use
data[] <- lapply(data, gsub, pattern = " ", replacement = "", fixed = TRUE)
or to constrict this to just the second and third columns (i.e. every column except the first),
data[-1] <- lapply(data[-1], gsub, pattern = " ", replacement = "", fixed = TRUE)
I would use a regex:
import re
new_list = [re.sub(r"\.(?=[^.]*$)", r". - ", s) for s in old_list]
There is also Induction app (http://inductionapp.com/), which is free & open source (https://github.com/Induction/Induction).
Just drag & drop your .sqlite file on the icon to open the file.
And the other great option is https://github.com/yepher/CoreDataUtility
While the answer provided by BalusC works for this case, it will break when the file path contains spaces because in a URL, these are being converted to %20 which is not a valid file name. If you construct the File object using a URI rather than a String, whitespaces will be handled correctly:
URL url = getClass().getResource("ListStopWords.txt");
File file = new File(url.toURI());
You need to create a Handler
in the UI thread and then use it to post or send a message from your other thread to update the UI
You can use Array.sort using a custom function as parameter to define your sorting mecanism.
In your example, it would give :
var Data = [
{id_list:1, name:'Nick',token:'312312'},{id_list:2,name:'John',token:'123123'}
]
Data.sort(function(a, b){
return a.name < b.name ? -1 : a.name > b.name ? 1 : 0;
});
alert("First name is : " + Data[0].name); // alerts 'John'
alert("Second name is : " + Data[1].name); // alerts 'Nick'
The sort function must return either -1 if a should come before b, 1 if a should come after b and 0 if both are equal. It's up to you to define the right logic in your sorting function to sort the array.
Edit : Missed the last part of your question where you want to know the index. You would have to loop through the array to find that as others have said.
You can add it by appending a Series to the dataframe as follows. I am assuming by blank you mean you want to add a row containing only "Nan". You can first create a Series object with Nan. Make sure you specify the columns while defining 'Series' object in the -Index parameter. The you can append it to the DF. Hope it helps!
from numpy import nan as Nan
import pandas as pd
>>> df1 = pd.DataFrame({'A': ['A0', 'A1', 'A2', 'A3'],
... 'B': ['B0', 'B1', 'B2', 'B3'],
... 'C': ['C0', 'C1', 'C2', 'C3'],
... 'D': ['D0', 'D1', 'D2', 'D3']},
... index=[0, 1, 2, 3])
>>> s2 = pd.Series([Nan,Nan,Nan,Nan], index=['A', 'B', 'C', 'D'])
>>> result = df1.append(s2)
>>> result
A B C D
0 A0 B0 C0 D0
1 A1 B1 C1 D1
2 A2 B2 C2 D2
3 A3 B3 C3 D3
4 NaN NaN NaN NaN
This one drove me crazy... basically you need two things:
1) Make sure your DNS is setup to point to your subdomain. This means to make sure you have an A Record in the DNS for your subdomain and point to the same IP.
2) You must add an additional website in IIS 7 named subdomain.example.com
Change setTimeout("changeImage()", 30000);
to setInterval("changeImage()", 30000);
and remove var timerid = setInterval(changeImage, 30000);
.
Just to add one more point to this:
R does have a data structure equivalent to the Python dict in the hash
package. You can read about it in this blog post from the Open Data Group. Here's a simple example:
> library(hash)
> h <- hash( keys=c('foo','bar','baz'), values=1:3 )
> h[c('foo','bar')]
<hash> containing 2 key-value pairs.
bar : 2
foo : 1
In terms of usability, the hash
class is very similar to a list. But the performance is better for large datasets.
ADD this
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT,MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 1);
}
when you will replace your code with this above code then automatically your this
public void onActivityResult(int requestCode, int resultCode,
@Nullable Intent data){}
Method will Start working
//No Need to write this code in onclick method
Intent intent=new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT)
startActivityForResult(intent,1);
Toast.makeText(getContext(), "image"+intent, Toast.LENGTH_SHORT).show();
Using Commons Collections:
EqualPredicate nameEqlPredicate = new EqualPredicate(3);
BeanPredicate beanPredicate = new BeanPredicate("age", nameEqlPredicate);
return CollectionUtils.filter(cats, beanPredicate);
just change wb to w
outfile=open('./immates.csv','wb')
to
outfile=open('./immates.csv','w')
Yes unfortunately it will always load the full file. If you're doing this repeatedly probably best to extract the sheets to separate CSVs and then load separately. You can automate that process with d6tstack which also adds additional features like checking if all the columns are equal across all sheets or multiple Excel files.
import d6tstack
c = d6tstack.convert_xls.XLStoCSVMultiSheet('multisheet.xlsx')
c.convert_all() # ['multisheet-Sheet1.csv','multisheet-Sheet2.csv']
I use method 3 because it's the most understandable for others (whenever you see an <a>
tag, you know it's a link) and when you are part of a team, you have to make simple things ;).
And finally I don't think it's useful and efficient to use JS simply to navigate to an other page.

file was lurkingI did what @Chole did - checked out of my IDE exited and looked at a git-status
once more. Then ran a $git add . $git commit -m'msg' $git push
It cleared the 2 terminals that were running commands and solved the problem. Hope this helps someone - the diagnostics were good so thanks all, very helpful.
A slow Mac has caused this problem before - so now I just wait for a bit before running a second commit that conflicts with the first.
Try:
Excel.Application oXL;
Excel._Workbook oWB;
Excel._Worksheet oSheet;
Excel.Range oRng;
oXL = new Excel.Application();
oXL.Visible = true;
oWB = (Excel._Workbook)(oXL.Workbooks.Add(Missing.Value));
oSheet = (Excel._Worksheet)oWB.Worksheets;
oSheet.Activate();
oSheet.Cells[3, 9] = "Some Text"
Just to build on vinnief's hacky solution above, I use MsgBox like this:
Browser.msgBox('BorderoToMatriz', Browser.Buttons.OK_CANCEL);
and it acts kinda like a break point, stops the script and outputs whatever string you need to a pop-up box. I find especially in Sheets, where I have trouble with Logger.log, this provides an adequate workaround most times.
I wanted to display logs on stdout and log file along with the timestamp. None of the above answers worked for me. I made use of process substitution and exec command and came up with the following code. Sample logs:
2017-06-21 11:16:41+05:30 Fetching information about files in the directory...
Add following lines at the top of your script:
LOG_FILE=script.log
exec > >(while read -r line; do printf '%s %s\n' "$(date --rfc-3339=seconds)" "$line" | tee -a $LOG_FILE; done)
exec 2> >(while read -r line; do printf '%s %s\n' "$(date --rfc-3339=seconds)" "$line" | tee -a $LOG_FILE; done >&2)
Hope this helps somebody!
Query to find out all the datatype of columns being used in any database
SELECT distinct DATA_TYPE FROM INFORMATION_SCHEMA.columns
WHERE table_schema = '<db_name>' AND column_name like '%';
Private variables in python is more or less a hack: the interpreter intentionally renames the variable.
class A:
def __init__(self):
self.__var = 123
def printVar(self):
print self.__var
Now, if you try to access __var
outside the class definition, it will fail:
>>>x = A()
>>>x.__var # this will return error: "A has no attribute __var"
>>>x.printVar() # this gives back 123
But you can easily get away with this:
>>>x.__dict__ # this will show everything that is contained in object x
# which in this case is something like {'_A__var' : 123}
>>>x._A__var = 456 # you now know the masked name of private variables
>>>x.printVar() # this gives back 456
You probably know that methods in OOP are invoked like this: x.printVar() => A.printVar(x)
, if A.printVar()
can access some field in x
, this field can also be accessed outside A.printVar()
...after all, functions are created for reusability, there is no special power given to the statements inside.
The game is different when there is a compiler involved (privacy is a compiler level concept). It know about class definition with access control modifiers so it can error out if the rules are not being followed at compile time
node --max_old_space_size=4096 ./node_modules/@angular/cli/bin/ng build --prod --build-optimizer
adding parameter --build-optimizer
resolved the issue in my case.
Update:
I am not sure why adding only --build-optimizer solves the issue but as per angular docs it should be used with aot enabled, so updated command should be like below
--build-optimizer=true --aot=true
From http://docs.python.org/tutorial/datastructures.html:
"The keys() method of a dictionary object returns a list of all the keys used in the dictionary, in arbitrary order (if you want it sorted, just apply the sorted() function to it)."
UPDATE test SET log = REPLACE(REPLACE(log, '\r', ''), '\n', '');
worked for me.
while its similar, it'll also get rid of \r\n
See http://api.jquery.com/jQuery.ajax/, there's mention of datatype and contentType there.
They are both used in the request to the server so the server knows what kind of data to receive/send.
You could access your class's __dict__
attribute:
for i in range(3)
self.__dict__['group%d' % i]=self.getGroup(selected, header+i)
But why can't you just use an array named group
?
yourView.setLayoutParams(new LinearLayout.LayoutParams(width, height));
One way:
set -- $(md5sum $file)
md5=$1
Another way:
md5=$(md5sum $file | while read sum file; do echo $sum; done)
Another way:
md5=$(set -- $(md5sum $file); echo $1)
(Do not try that with back-ticks unless you're very brave and very good with backslashes.)
The advantage of these solutions over other solutions is that they only invoke md5sum
and the shell, rather than other programs such as awk
or sed
. Whether that actually matters is then a separate question; you'd probably be hard pressed to notice the difference.
