For more general boolean functions that you would like to use as a filter and that depend on more than one column, you can use:
df = df[df[['col_1','col_2']].apply(lambda x: f(*x), axis=1)]
where f is a function that is applied to every pair of elements (x1, x2) from col_1 and col_2 and returns True or False depending on any condition you want on (x1, x2).
Android Support V7 GridLayout library makes excess space distribution easy by accommodating the principle of weight. To make a column stretch, make sure the components inside it define a weight or a gravity. To prevent a column from stretching, ensure that one of the components in the column does not define a weight or a gravity. Remember to add dependency for this library. Add com.android.support:gridlayout-v7:25.0.1 in build.gradle.

If you want to both OnTouch
and OnClick
listener to parent and child view both, please use below trick:
User ScrollView as a Parent view and inside that placed your child view inside Relative/LinearLayout.
Make Parent ScrollView android:fillViewport="true"
so View not be scrolled.
Then set OnTouch
listener to parent and OnClick
listener to Child views.
And enjoy both listener callbacks.
The default behavior is:
If the parameter is a primitive type (int
, bool
, double
, ...), Web API tries to get the value from the URI of the HTTP request.
For complex types (your own object, for example: Person
), Web API tries to read the value from the body of the HTTP request.
So, if you have:
...then you don't have to add any attributes (neither [FromBody]
nor [FromUri]
).
But, if you have a primitive type in the body, then you have to add [FromBody]
in front of your primitive type parameter in your WebAPI controller method. (Because, by default, WebAPI is looking for primitive types in the URI of the HTTP request.)
Or, if you have a complex type in your URI, then you must add [FromUri]
. (Because, by default, WebAPI is looking for complex types in the body of the HTTP request by default.)
Primitive types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post([FromBody]int id)
{
}
// api/users/id
public HttpResponseMessage Post(int id)
{
}
}
Complex types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post(User user)
{
}
// api/users/user
public HttpResponseMessage Post([FromUri]User user)
{
}
}
This works as long as you send only one parameter in your HTTP request. When sending multiple, you need to create a custom model which has all your parameters like this:
public class MyModel
{
public string MyProperty { get; set; }
public string MyProperty2 { get; set; }
}
[Route("search")]
[HttpPost]
public async Task<dynamic> Search([FromBody] MyModel model)
{
// model.MyProperty;
// model.MyProperty2;
}
From Microsoft's documentation for parameter binding in ASP.NET Web API:
When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object). At most one parameter is allowed to read from the message body.
This should work:
public HttpResponseMessage Post([FromBody] string name) { ... }
This will not work:
// Caution: This won't work! public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }
The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.
You need to set the location
header as follows:
header('Location: http://www.example.com/');
Replacing http://www.example.com
of course with the url of your landing page.
Add this where you have finished logging the user in.
Note: When redirecting the user will be immediately redirected so you're message probably won't display.
Additionally, you need to move your PHP code to the top of the file for this solution to work.
On another side note, please see my comment above regarding the use of the deprecated mysql
statements and consider using the newer, safer and improved mysqli
or PDO
statements.
As others have pointed out, .find()
is the way to go when looking for one object within your array. However, if your object cannot be found using this method, your program will crash:
const myArray = [{'id':'73','foo':'bar'},{'id':'45','foo':'bar'}];_x000D_
const res = myArray.find(x => x.id === '100').foo; // Uh oh!_x000D_
/*_x000D_
Error:_x000D_
"Uncaught TypeError: Cannot read property 'foo' of undefined"_x000D_
*/
_x000D_
This can be fixed by checking whether the result of .find()
is defined before using using .foo
on it. Modern JS allows us to do this easily with optional chaining, returning undefined
if the object cannot be found, rather than crashing your code:
const myArray = [{'id':'73','foo':'bar'},{'id':'45','foo':'bar'}];_x000D_
const res = myArray.find(x => x.id === '100')?.foo; // No error!_x000D_
console.log(res); // undefined when the object cannot be found
_x000D_
The correct fix is to add the property in the type definition as explained by @Nitzan Tomer.
But also you can just define property as any
, if you want to write code almost as in JavaScript:
arr.filter((item:any) => {
return item.isSelected == true;
}
None of these answers is particularly clear or simple.
Here is a clear, simple method that is guaranteed to work.
accumulate_normalize_probabilities takes a dictionary p
that maps symbols to probabilities OR frequencies. It outputs usable list of tuples from which to do selection.
def accumulate_normalize_values(p):
pi = p.items() if isinstance(p,dict) else p
accum_pi = []
accum = 0
for i in pi:
accum_pi.append((i[0],i[1]+accum))
accum += i[1]
if accum == 0:
raise Exception( "You are about to explode the universe. Continue ? Y/N " )
normed_a = []
for a in accum_pi:
normed_a.append((a[0],a[1]*1.0/accum))
return normed_a
Yields:
>>> accumulate_normalize_values( { 'a': 100, 'b' : 300, 'c' : 400, 'd' : 200 } )
[('a', 0.1), ('c', 0.5), ('b', 0.8), ('d', 1.0)]
Why it works
The accumulation step turns each symbol into an interval between itself and the previous symbols probability or frequency (or 0 in the case of the first symbol). These intervals can be used to select from (and thus sample the provided distribution) by simply stepping through the list until the random number in interval 0.0 -> 1.0 (prepared earlier) is less or equal to the current symbol's interval end-point.
The normalization releases us from the need to make sure everything sums to some value. After normalization the "vector" of probabilities sums to 1.0.
The rest of the code for selection and generating a arbitrarily long sample from the distribution is below :
def select(symbol_intervals,random):
print symbol_intervals,random
i = 0
while random > symbol_intervals[i][1]:
i += 1
if i >= len(symbol_intervals):
raise Exception( "What did you DO to that poor list?" )
return symbol_intervals[i][0]
def gen_random(alphabet,length,probabilities=None):
from random import random
from itertools import repeat
if probabilities is None:
probabilities = dict(zip(alphabet,repeat(1.0)))
elif len(probabilities) > 0 and isinstance(probabilities[0],(int,long,float)):
probabilities = dict(zip(alphabet,probabilities)) #ordered
usable_probabilities = accumulate_normalize_values(probabilities)
gen = []
while len(gen) < length:
gen.append(select(usable_probabilities,random()))
return gen
Usage :
>>> gen_random (['a','b','c','d'],10,[100,300,400,200])
['d', 'b', 'b', 'a', 'c', 'c', 'b', 'c', 'c', 'c'] #<--- some of the time
Sounds like you need to create your own pair class (see discussion here). Then make a List of that pair class you created

Apparently my antivirus (Ad-Aware) was flagging a DLL one of my projects depends on, and deleting it. Even after excluding the directory where the DLL lives, the same behaviour continued until I restarted my computer.
simply "CUT" project folder and move it out of workspace directory and do the following
file=>import=>(select new directory)=> mark (copy to my workspace) checkbox
and you done !

At first check out that your linked server is in the list by this query
select name from sys.servers
If it not exists then try to add to the linked server
EXEC sp_addlinkedserver @server = 'SERVER_NAME' --or may be server ip address
After that login to that linked server by
EXEC sp_addlinkedsrvlogin 'SERVER_NAME'
,'false'
,NULL
,'USER_NAME'
,'PASSWORD'
Then you can do whatever you want ,treat it like your local server
exec [SERVER_NAME].[DATABASE_NAME].dbo.SP_NAME @sample_parameter
Finally you can drop that server from linked server list by
sp_dropserver 'SERVER_NAME', 'droplogins'

A production quality program should use one of the many logging alternatives (e.g. log4j, logback, java.util.logging) to report errors and other diagnostics. This has a number of advantages:
By contrast, if you just use printStackTrace, the deployer / end user has little if any control, and logging messages are liable to either be lost or shown to the end user in inappropriate circumstances. (And nothing terrifies a timid user more than a random stack trace.)
when you make a COUNT(*) in your mysql statement like in
$q = $db->query("SELECT COUNT(*) FROM ...");
your mysql query is already counting the number of result why counting again in php? to get the result of your mysql
$q = $db->query("SELECT COUNT(*) as counted FROM ...");
$nb = $q->fetch(PDO::FETCH_OBJ);
$nb = $nb->counted;
and $nb
will contain the integer you have counted with your mysql statement
a bit long to write but fast to execute
Edit: sorry for the wrong post but as some example show query with count in, I was suggesting using the mysql result, but if you don't use the count in sql fetchAll() is efficient, if you save the result in a variable you won't loose a line.
$data = $dbh->query("SELECT * FROM ...");
$table = $data->fetchAll(PDO::FETCH_OBJ);
count($table)
will return the number of row and you can still use the result after like $row = $table[0]
or using a foreach
foreach($table as $row){
print $row->id;
}
To literally fix your example you would use this:
Sub Normalize()
Dim Ticker As Range
Sheets("Sheet1").Activate
Set Ticker = Range(Cells(2, 1), Cells(65, 1))
Ticker.Copy
Sheets("Sheet2").Select
Cells(1, 1).PasteSpecial xlPasteAll
End Sub
To Make slight improvments on it would be to get rid of the Select and Activates:
Sub Normalize()
With Sheets("Sheet1")
.Range(.Cells(2, 1), .Cells(65, 1)).Copy Sheets("Sheet2").Cells(1, 1)
End With
End Sub
but using the clipboard takes time and resources so the best way would be to avoid a copy and paste and just set the values equal to what you want.
Sub Normalize()
Dim CopyFrom As Range
Set CopyFrom = Sheets("Sheet1").Range("A2", [A65])
Sheets("Sheet2").Range("A1").Resize(CopyFrom.Rows.Count).Value = CopyFrom.Value
End Sub
To define the CopyFrom
you can use anything you want to define the range, You could use Range("A2:A65")
, Range("A2",[A65])
, Range("A2", "A65")
all would be valid entries. also if the A2:A65 Will never change the code could be further simplified to:
Sub Normalize()
Sheets("Sheet2").Range("A1:A65").Value = Sheets("Sheet1").Range("A2:A66").Value
End Sub
I added the Copy from range, and the Resize
property to make it slightly more dynamic in case you had other ranges you wanted to use in the future.
And note that since Python types are only checked at runtime you can have code like:
if True:
x = 2
y = 4
else:
x = "One"
y = "Two"
print(x + y)
But I'm having trouble thinking of other ways in which the code would operate without an error because of type issues.
When you use recv
in connection with select
if the socket is ready to be read from but there is no data to read that means the client has closed the connection.
Here is some code that handles this, also note the exception that is thrown when recv
is called a second time in the while loop. If there is nothing left to read this exception will be thrown it doesn't mean the client has closed the connection :
def listenToSockets(self):
while True:
changed_sockets = self.currentSockets
ready_to_read, ready_to_write, in_error = select.select(changed_sockets, [], [], 0.1)
for s in ready_to_read:
if s == self.serverSocket:
self.acceptNewConnection(s)
else:
self.readDataFromSocket(s)
And the function that receives the data :
def readDataFromSocket(self, socket):
data = ''
buffer = ''
try:
while True:
data = socket.recv(4096)
if not data:
break
buffer += data
except error, (errorCode,message):
# error 10035 is no data available, it is non-fatal
if errorCode != 10035:
print 'socket.error - ('+str(errorCode)+') ' + message
if data:
print 'received '+ buffer
else:
print 'disconnected'
In short, to ensure proper unicode handling in Python 2:
io.open

print(text.encode('ascii', 'replace').decode())

I modified my activate script to source the file .virtualenvrc
, if it exists in the current directory, and to save/restore PYTHONPATH
on activate/deactivate.
You can find the patched activate
script here.. It's a drop-in replacement for the activate script created by virtualenv 1.11.6.
Then I added something like this to my .virtualenvrc
:
export PYTHONPATH="${PYTHONPATH:+$PYTHONPATH:}/some/library/path"
This is probably a good starting point (version 8.4+ only):
SELECT id_field, array_agg(value_field1), array_agg(value_field2)
FROM data_table
GROUP BY id_field
array_agg returns an array, but you can CAST that to text and edit as needed (see clarifications, below).
Prior to version 8.4, you have to define it yourself prior to use:
CREATE AGGREGATE array_agg (anyelement)
(
sfunc = array_append,
stype = anyarray,
initcond = '{}'
);
(paraphrased from the PostgreSQL documentation)
Clarifications:
In practice, the models are used as follows.
In discriminative models, to predict the label y
from the training example x
, you must evaluate:
which merely chooses what is the most likely class y
considering x
. It's like we were trying to model the decision boundary between the classes. This behavior is very clear in neural networks, where the computed weights can be seen as a complexly shaped curve isolating the elements of a class in the space.
Now, using Bayes' rule, let's replace the in the equation by . Since you are just interested in the arg max, you can wipe out the denominator, that will be the same for every y
. So, you are left with
which is the equation you use in generative models.
While in the first case you had the conditional probability distribution p(y|x)
, which modeled the boundary between classes, in the second you had the joint probability distribution p(x, y)
, since p(x | y) p(y) = p(x, y)
, which explicitly models the actual distribution of each class.
With the joint probability distribution function, given a y
, you can calculate ("generate") its respective x
. For this reason, they are called "generative" models.
By using this way you can get the list of selected records.
GregorianCalendar gregorianCalendar = new GregorianCalendar();
Criteria cri = session.createCriteria(ProjectActivities.class);
cri.add(Restrictions.ge("EffectiveFrom", gregorianCalendar.getTime()));
List list = cri.list();
All the Records will be generated into list which are greater than or equal to '08-Oct-2012' or else pass the date of user acceptance date at 2nd parameter of Restrictions (gregorianCalendar.getTime()
) of criteria to get the records.
You have misunderstood the Python list
object. It is similar to a C pointer-array
. It does not actually "copy" the object which you append to it. Instead, it just store a "pointer" to that object.
Try the following code:
>>> d={}
>>> dlist=[]
>>> for i in xrange(0,3):
d['data']=i
dlist.append(d)
print(d)
{'data': 0}
{'data': 1}
{'data': 2}
>>> print(dlist)
[{'data': 2}, {'data': 2}, {'data': 2}]
So why is print(dlist)
not the same as print(d)
?
The following code shows you the reason:
>>> for i in dlist:
print "the list item point to object:", id(i)
the list item point to object: 47472232
the list item point to object: 47472232
the list item point to object: 47472232
So you can see all the items in the dlist
is actually pointing to the same dict
object.
The real answer to this question will be to append the "copy" of the target item, by using d.copy()
.
>>> dlist=[]
>>> for i in xrange(0,3):
d['data']=i
dlist.append(d.copy())
print(d)
{'data': 0}
{'data': 1}
{'data': 2}
>>> print dlist
[{'data': 0}, {'data': 1}, {'data': 2}]
Try the id()
trick, you can see the list items actually point to completely different objects.
>>> for i in dlist:
print "the list item points to object:", id(i)
the list item points to object: 33861576
the list item points to object: 47472520
the list item points to object: 47458120
Try using something like

This selects/deletes all duplicate records except one record from each group of duplicates. So, the delete leaves all unique records + one record from each group of the duplicates.
Select duplicates:
SELECT *
FROM table
WHERE
id NOT IN (
SELECT MIN(id)
FROM table
GROUP BY column1, column2
);
Delete duplicates:
DELETE FROM table
WHERE
id NOT IN (
SELECT MIN(id)
FROM table
GROUP BY column1, column2
);
Be aware of larger amounts of records, it can cause performance problems.
If you want to have more flexibility with filenames and compression options, you can use:
find /my/path/ -type f -name "*.sql" -o -name "*.log" -exec \
tar -P --transform='s@/my/path/@@g' -cf - {} + | \
pigz -9 -p 4 > myarchive.tar.gz
find
find /my/path/ -type f -name "*.sql" -o -name "*.log" -exec
This command will look for the files you want to archive, in this case /my/path/*.sql
and /my/path/*.log
. Add as many -o -name "pattern"
as you want.
-exec
will execute the next command using the results of find
: tar
tar
tar -P --transform='s@/my/path/@@g' -cf - {} +
--transform
is a simple string replacement parameter. It will strip the path of the files from the archive so the tarball's root becomes the current directory when extracting. Note that you can't use -C
option to change directory as you'll lose benefits of find
: all files of the directory would be included.
-P
tells tar
to use absolute paths, so it doesn't trigger the warning "Removing leading `/' from member names". Leading '/' with be removed by --transform
anyway.
-cf -
tells tar
to use the tarball name we'll specify later
{} +
uses everyfiles that find
found previously
pigz
pigz -9 -p 4
Use as many parameters as you want.
In this case -9
is the compression level and -p 4
is the number of cores dedicated to compression.
If you run this on a heavy loaded webserver, you probably don't want to use all available cores.

If your WS-RS needs raise an error why not just use the WebApplicationException?

if (idLanguage== 0){

ResponseBuilder builder = Response.status(Response.Status.BAD_REQUEST);
builder.entity("Missing idLanguage parameter on request");
Response response = builder.build();
throw new WebApplicationException(response);
}
... //other stuff to return my entity
return myEntity;

Have a look at frequent-cron - it's old but very stable and you can step down to micro-seconds. At this point in time, the only thing that I would say against it is that I'm still trying to work out how to install it outside of init.d but as a native systemd service, but certainly up to Ubuntu 18 it's running just fine still using init.d (distance may vary on latter versions). It has the added advantage (?) of ensuring that it won't spawn another instance of the PHP script unless a prior one has completed, which reduces potential memory leakage issues.
Union will fetch data by row not column,So If your are like me who is looking for fetching column data from two different table with no relation and without join.
In my case I am fetching state name and country name by id. Instead of writing two query you can do this way.
select
(
select s.state_name from state s where s.state_id=3
) statename,
(
select c.description from country c where c.id=5
) countryname
from dual;
where dual is a dummy table with single column--anything just require table to view

Please consider that:
Some data (like URLs) can be sent over the Internet using the ASCII character-set. Since data often contain characters outside the ASCII set, so it has to be converted into a valid ASCII format.
To find it yourself, you can visit https://en.wikipedia.org/wiki/ASCII, there you can find big tables of characters. The one you are looking is in Control Characters
table.
Digging to table you can find
Oct Dec Hex Name
012 10 0A Line Feed
In the html file you can use Dec and Hex representation of charters
The Dec
is represented with
The Hex
is represented with 

(or you can omit the leading zero 

)
There is a good converter at https://r12a.github.io/apps/conversion/ .
The answer given by P????? creates a nullable bool, not a bool, which may be fine for you. For example in C# it would create: bool? AdminApproved
not bool AdminApproved
.
If you need to create a bool (defaulting to false):
ALTER TABLE person
ADD AdminApproved BIT
DEFAULT 0 NOT NULL;
For HSQLDB:
ALTER TABLE tableName ALTER COLUMN columnName SET NULL;
I made this implementation in kotlin I thing is not very efficient but works ivIsSelected is a ImageView that represent in my case a check mark
var selectedItems = mutableListOf<Int>(-1)
override fun onBindViewHolder(holder: ContactViewHolder, position: Int) {
// holder.setData(ContactViewModel, position) // I'm passing this to the ViewHolder
holder.itemView.setBackgroundColor(Color.WHITE)
holder.itemView.ivIsSelected.visibility = INVISIBLE
selectedItems.forEach {
if (it == position) {
holder.itemView.setBackgroundColor(Color.argb(45, 0, 255, 43))
holder.itemView.ivIsSelected.visibility = VISIBLE
}
}
holder.itemView.setOnClickListener { it ->
it.setBackgroundColor(Color.BLUE)
selectedItems.add(position)
selectedItems.forEach { selectedItem -> // this forEach is required to refresh all the list
notifyItemChanged(selectedItem)
}
}
}
I've set the time to 1000*36000.

now.setTime(expireTime);
document.cookie = 'cookie=ok;expires='+now.toUTCString()+';path=/';

I solved this problem on windows setting up sdk path in configuration option.
you can use myfaces tomahawk component
http://myfaces.apache.org/tomahawk-project/tomahawk12/tagdoc/t_div.html
as noted here, this is what worked best for me:
sudo apt-get install python3 python3-pip python3-setuptools
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
How about mkString ?
theStrings.mkString(",")
A variant exists in which you can specify a prefix and suffix too.
See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.

Use the LayoutInflater
to create a view based on your layout template, and then inject it into the view where you need it.
LayoutInflater vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = vi.inflate(R.layout.your_layout, null);
// fill in any details dynamically here
TextView textView = (TextView) v.findViewById(R.id.a_text_view);
textView.setText("your text");
// insert into main view
ViewGroup insertPoint = (ViewGroup) findViewById(R.id.insert_point);
insertPoint.addView(v, 0, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
You may have to adjust the index where you want to insert the view.
Additionally, set the LayoutParams according to how you would like it to fit in the parent view. e.g. with FILL_PARENT
, or MATCH_PARENT
, etc.
If you want to have projects choice list when you open Git Bash:

#!/bin/bash
ppath="/d/-projects/-github"
cd $ppath
unset PROJECTS

Basically, the data is stored in an Array and the options are added accordingly. I think the code says more than a thousand words.
var data = [ // The data
['ten', [
'eleven','twelve'
]],
['twenty', [
'twentyone', 'twentytwo'
]]
];
$a = $('#a'); // The dropdowns
$b = $('#b');
for(var i = 0; i < data.length; i++) {
var first = data[i][0];
$a.append($("<option>"). // Add options
attr("value",first).
data("sel", i).
text(first));
}
$a.change(function() {
var index = $(this).children('option:selected').data('sel');
var second = data[index][1]; // The second-choice data
$b.html(''); // Clear existing options in second dropdown
for(var j = 0; j < second.length; j++) {
$b.append($("<option>"). // Add options
attr("value",second[j]).
data("sel", j).
text(second[j]));
}
}).change(); // Trigger once to add options at load of first choice
its just simple
select * from myTable where year(columnX) = 2010
InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
The accepted answer mentions
Get-ChildItem -Recurse | ?{ $_.PSIsContainer } | Select-Object FullName
to get a "raw string".
But in fact objects of type Selected.System.IO.DirectoryInfo
will be returned. For raw strings the following can be used:
Get-ChildItem -Recurse | ?{ $_.PSIsContainer } | % { $_.FullName }
The difference matters if the value is concatenated to a string:
Select-Object
suprisingly foo\@{FullName=bar}
ForEach
-operator the expected: foo\bar
This will maybe give you a hint on what went wrong.
import java.math.BigDecimal;
public class Main {
public static void main(String[] args) {
BigDecimal bdTest = new BigDecimal(0.745);
BigDecimal bdTest1 = new BigDecimal("0.745");
bdTest = bdTest.setScale(2, BigDecimal.ROUND_HALF_UP);
bdTest1 = bdTest1.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("bdTest:" + bdTest); // prints "bdTest:0.74"
System.out.println("bdTest1:" + bdTest1); // prints "bdTest:0.75"
}
}
The problem is, that your input (a double x=0.745;
) can not represent 0.745 exactly. It actually saves a value slightly lower. For BigDecimals
, this is already below 0.745, so it rounds down...
Try not to use the BigDecimal(double/float)
constructors.
The only conditions available in CSS are selectors and @media. Some browsers support some of the CSS 3 selectors and media queries.
You can modify an element with JavaScript to change if it matches a selector or not (e.g. by adding a new class).
Why you are using PHP for the conversion. Now, there are so many front end languages available, Why you are still including a server? You can convert the password into the binary number in the front-end and send the converted string in the Database. According to my point of view, this would be convenient.
var bintext, textresult="", binlength;
this.aaa = this.text_value;
bintext = this.aaa.replace(/[^01]/g, "");
binlength = bintext.length-(bintext.length%8);
for(var z=0; z<binlength; z=z+8) {
textresult += String.fromCharCode(parseInt(bintext.substr(z,8),2));
this.ans = textresult;
This is a Javascript code which I have found here: http://binarytotext.net/, they have used this code with Vue.js. In the code, this.aaa is the v-model dynamic value. To convert the binary into the text values, they have used big numbers. You need to install an additional package and convert it back into the text field. In my point of view, it would be easy.
Check your file: settings.gradle
for presence lines with included subprojects (for example:
include chapter1-bookstore
)
GROUP BY 1
I've never known GROUP BY to support using ordinals, only ORDER BY. Either way, only MySQL supports GROUP BY's not including all columns without aggregate functions performed on them. Ordinals aren't recommended practice either because if they're based on the order of the SELECT - if that changes, so does your ORDER BY (or GROUP BY if supported).
There's no need to run GROUP BY
on the contents when you're using UNION
- UNION ensures that duplicates are removed; UNION ALL
is faster because it doesn't - and in that case you would need the GROUP BY...
Your query only needs to be:
SELECT a.id,
a.time
FROM dbo.TABLE_A a
UNION
SELECT b.id,
b.time
FROM dbo.TABLE_B b
Because, as said in other answers, class enum are not implicitly convertible to int/bool, it also helps to avoid buggy code like:
enum MyEnum {
Value1,
Value2,
};
...
if (var == Value1 || Value2) // Should be "var == Value2" no error/warning
a { text-indent:-9999px; }
Tends to work well from my exprience.
Here's an httplib
solution that behaves like urllib2. You can just give it a URL and it just works. No need to mess about splitting up your URLs into hostname and path. This function already does that.
import httplib
import socket
def get_link_status(url):
"""
Gets the HTTP status of the url or returns an error associated with it. Always returns a string.
"""
https=False
url=re.sub(r'(.*)#.*$',r'\1',url)
url=url.split('/',3)
if len(url) > 3:
path='/'+url[3]
else:
path='/'
if url[0] == 'http:':
port=80
elif url[0] == 'https:':
port=443
https=True
if ':' in url[2]:
host=url[2].split(':')[0]
port=url[2].split(':')[1]
else:
host=url[2]
try:
headers={'User-Agent':'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0',
'Host':host
}
if https:
conn=httplib.HTTPSConnection(host=host,port=port,timeout=10)
else:
conn=httplib.HTTPConnection(host=host,port=port,timeout=10)
conn.request(method="HEAD",url=path,headers=headers)
response=str(conn.getresponse().status)
conn.close()
except socket.gaierror,e:
response="Socket Error (%d): %s" % (e[0],e[1])
except StandardError,e:
if hasattr(e,'getcode') and len(e.getcode()) > 0:
response=str(e.getcode())
if hasattr(e, 'message') and len(e.message) > 0:
response=str(e.message)
elif hasattr(e, 'msg') and len(e.msg) > 0:
response=str(e.msg)
elif type('') == type(e):
response=e
else:
response="Exception occurred without a good error message. Manually check the URL to see the status. If it is believed this URL is 100% good then file a issue for a potential bug."
return response
You could also use float and inline-block to center your nav like the following:
nav li {
float: left;
}
nav {
display: inline-block;
}
You can try onload event as well;
var createIframe = function (src) {
var self = this;
$('<iframe>', {
src: src,
id: 'iframeId',
frameborder: 1,
scrolling: 'no',
onload: function () {
self.isIframeLoaded = true;
console.log('loaded!');
}
}).appendTo('#iframeContainer');
};
Here is some code that show how it works.
class Test
{
public static void main(String args[])
{
System.out.println(Test.test());
}
public static String test()
{
try {
System.out.println("try");
throw new Exception();
} catch(Exception e) {
System.out.println("catch");
return "return";
} finally {
System.out.println("finally");
return "return in finally";
}
}
}
The results is:
try
catch
finally
return in finally
There are a lot of good answers here, but I only want to add one thing. It sometimes happens that you want to scroll your ScrollView to a specific view of the layout, instead of a full scroll to the top or the bottom.
A simple example: in a registration form, if the user tap the "Signup" button when a edit text of the form is not filled, you want to scroll to that specific edit text to tell the user that he must fill that field.
In that case, you can do something like that:
scrollView.post(new Runnable() {
public void run() {
scrollView.scrollTo(0, editText.getBottom());
}
});
or, if you want a smooth scroll instead of an instant scroll:
scrollView.post(new Runnable() {
public void run() {
scrollView.smoothScrollTo(0, editText.getBottom());
}
});
Obviously you can use any type of view instead of Edit Text. Note that getBottom() returns the coordinates of the view based on its parent layout, so all the views used inside the ScrollView should have only a parent (for example a Linear Layout).
If you have multiple parents inside the child of the ScrollView, the only solution i've found is to call requestChildFocus on the parent view:
editText.getParent().requestChildFocus(editText, editText);
but in this case you cannot have a smooth scroll.
I hope this answer can help someone with the same problem.
Something like this in your form main. Double click the form in the visual editor to create the form load event.
Timer Clock=new Timer();
Clock.Interval=2700000; // not sure if this length of time will work
Clock.Start();
Clock.Tick+=new EventHandler(Timer_Tick);
Then add an event handler to do something when the timer fires.
public void Timer_Tick(object sender,EventArgs eArgs)
{
if(sender==Clock)
{
// do something here
}
}
I had a problem with the same symtoms. In my case, it turned out that my submit function was missing the "return" statement.
For example:
$("#id_form").on("submit", function(){
//Code: Action (like ajax...)
return false;
})
There are the following way to select first child
1) $('.second div:first-child')
2) $('.second *:first-child')
3) $('div:first-child', '.second')
4) $('*:first-child', '.second')
5) $('.second div:nth-child(1)')
6) $('.second').children().first()
7) $('.second').children().eq(0)
I like the last two answers, but I experienced an issue if the the subclass referenced "this"
in ngOnDestroy
.
I modified it to be this, and it looks like it resolved that issue.
export abstract class BaseComponent implements OnDestroy {
protected componentDestroyed$: Subject<boolean>;
constructor() {
this.componentDestroyed$ = new Subject<boolean>();
let f = this.ngOnDestroy;
this.ngOnDestroy = function() {
// without this I was getting an error if the subclass had
// this.blah() in ngOnDestroy
f.bind(this)();
this.componentDestroyed$.next(true);
this.componentDestroyed$.complete();
};
}
/// placeholder of ngOnDestroy. no need to do super() call of extended class.
ngOnDestroy() {}
}
If you want to stick with the original List instead of creating a new one, you can something similar to what the Distinct()
extension method does internally, i.e. use a HashSet to check for uniqueness:
HashSet<long> set = new HashSet<long>(longs.Count);
longs.RemoveAll(x => !set.Add(x));
The List class provides this convenient RemoveAll(predicate)
method that drops all elements not satisfying the condition specified by the predicate. The predicate is a delegate taking a parameter of the list's element type and returning a bool value. The HashSet's Add()
method returns true only if the set doesn't contain the item yet. Thus by removing any items from the list that can't be added to the set you effectively remove all duplicates.
If you want to use less code, you can also use the norm
in the stats
package (the 'F' stands for Forbenius, which is the Euclidean norm):
norm(matrix(x1-x2), 'F')
While this may look a bit neater, it's not faster. Indeed, a quick test on very large vectors shows little difference, though so12311's method is slightly faster. We first define:
set.seed(1234)
x1 <- rnorm(300000000)
x2 <- rnorm(300000000)
Then testing for time yields the following:
> system.time(a<-sqrt(sum((x1-x2)^2)))
user system elapsed
1.02 0.12 1.18
> system.time(b<-norm(matrix(x1-x2), 'F'))
user system elapsed
0.97 0.33 1.31
JRE executes the application but JVM reads the instructions line by line so it's interpreter.

You can install directly from the repository (note the type="source"
):
install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")
I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.
set codedirectory=C:\Users\code
for /r %codedirectory% %%i in (*.c) do
( some GCC commands )
It's because you're missing position:relative;
on #contentframe
<div id="contentframe" style="position:relative; top: 160px; left: 0px;">
position:absolute;
positions itself against the closest ancestor that has a position
that is not static
. Since the default is static
that is what was causing your issue.
You have to put a g
at the end, it stands for "global":
echo dog dog dos | sed -r 's:dog:log:g'

There is the "Compare" plugin. You can install it via Plugins > Plugin Manager.
Alternatively you can install a specialized file compare software like WinMerge.
Change this line:
mMyListView.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
listItems));
to:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
listItems)
mMyListView.setAdapter(adapter);
and after updating the value of a list item, call:
adapter.notifyDataSetChanged();
I don't know whenever I use "/" in repository name it is replaced by "-" maybe github changed method of creating folders.
So I'm going to tell you what I did to create a empty folder and to add files.
I think, the difference is in usage patterns.
I would prefer .on
over .click
because the former can use less memory and work for dynamically added elements.
Consider the following html:
<html>
<button id="add">Add new</button>
<div id="container">
<button class="alert">alert!</button>
</div>
</html>
where we add new buttons via
$("button#add").click(function() {
var html = "<button class='alert'>Alert!</button>";
$("button.alert:last").parent().append(html);
});
and want "Alert!" to show an alert. We can use either "click" or "on" for that.
click
$("button.alert").click(function() {
alert(1);
});
with the above, a separate handler gets created for every single element that matches the selector. That means
.on
$("div#container").on('click', 'button.alert', function() {
alert(1);
});
with the above, a single handler for all elements that match your selector, including the ones created dynamically.
.on
As Adrien commented below, another reason to use .on
is namespaced events.
If you add a handler with .on("click", handler)
you normally remove it with .off("click", handler)
which will remove that very handler. Obviously this works only if you have a reference to the function, so what if you don't ? You use namespaces:
$("#element").on("click.someNamespace", function() { console.log("anonymous!"); });
with unbinding via
$("#element").off("click.someNamespace");
You can simply 'add' the arrays:
>> $a = array(1, 2, 3);
array (
0 => 1,
1 => 2,
2 => 3,
)
>> $b = array("a" => 1, "b" => 2, "c" => 3)
array (
'a' => 1,
'b' => 2,
'c' => 3,
)
>> $a + $b
array (
0 => 1,
1 => 2,
2 => 3,
'a' => 1,
'b' => 2,
'c' => 3,
)
To get the type, use the builtin type
function. With the in
operator, you can test if the type is a numpy type by checking if it contains the string numpy
;
In [1]: import numpy as np
In [2]: a = np.array([1, 2, 3])
In [3]: type(a)
Out[3]: <type 'numpy.ndarray'>
In [4]: 'numpy' in str(type(a))
Out[4]: True
(This example was run in IPython, by the way. Very handy for interactive use and quick tests.)
Is it "safe" to use
$_SERVER['HTTP_HOST']
for all links on a site without having to worry about XSS attacks, even when used in forms?
Yes, it's safe to use $_SERVER['HTTP_HOST']
, (and even $_GET
and $_POST
) as long as you verify them before accepting them. This is what I do for secure production servers:
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
$reject_request = true;
if(array_key_exists('HTTP_HOST', $_SERVER)){
$host_name = $_SERVER['HTTP_HOST'];
// [ need to cater for `host:port` since some "buggy" SAPI(s) have been known to return the port too, see http://goo.gl/bFrbCO
$strpos = strpos($host_name, ':');
if($strpos !== false){
$host_name = substr($host_name, $strpos);
}
// ]
// [ for dynamic verification, replace this chunk with db/file/curl queries
$reject_request = !array_key_exists($host_name, array(
'a.com' => null,
'a.a.com' => null,
'b.com' => null,
'b.b.com' => null
));
// ]
}
if($reject_request){
// log errors
// display errors (optional)
exit;
}
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
echo 'Hello World!';
// ...
The advantage of $_SERVER['HTTP_HOST']
is that its behavior is more well-defined than $_SERVER['SERVER_NAME']
. Contrast ??:
Contents of the Host: header from the current request, if there is one.
with:
The name of the server host under which the current script is executing.
Using a better defined interface like $_SERVER['HTTP_HOST']
means that more SAPIs will implement it using reliable well-defined behavior. (Unlike the other.) However, it is still totally SAPI dependent ??:
There is no guarantee that every web server will provide any of these [
$_SERVER
entries]; servers may omit some, or provide others not listed here.
To understand how to properly retrieve the host name, first and foremost you need to understand that a server which contains only code has no means of knowing (pre-requisite for verifying) its own name on the network. It needs to interface with a component that supplies it its own name. This can be done via:
local config file
local database
hardcoded source code
external request (curl)
client/attacker's Host:
request
etc
Usually its done via the local (SAPI) config file. Note that you have configured it correctly, e.g. in Apache ??:
A couple of things need to be 'faked' to make the dynamic virtual host look like a normal one.
The most important is the server name which is used by Apache to generate self-referential URLs, etc. It is configured with the
ServerName
directive, and it is available to CGIs via theSERVER_NAME
environment variable.The actual value used at run time is controlled by the UseCanonicalName setting.
With
UseCanonicalName Off
the server name comes from the contents of theHost:
header in the request. WithUseCanonicalName DNS
it comes from a reverse DNS lookup of the virtual host's IP address. The former setting is used for name-based dynamic virtual hosting, and the latter is used for** IP-based hosting.If Apache cannot work out the server name because there is no
Host:
header or the DNS lookup fails then the value configured withServerName
is used instead.
I would just like to add that in my case rubygems
wasn't installed.
Running sudo apt-get install rubygems

To find out if it's visible with plain JavaScript, check whether the display property is 'none' (don't check for 'block', it could also be blank or 'inline' and still be visible):
var isVisible = (elt.style.display != "none");
If you are using jQuery, you can use this instead:
var isVisible = $elt.is(":visible");
In PHP7.3 still working...

If declared using var, the property will be defined as public.
Step 1: See all your databases:
show dbs
Step 2: Select the database
use your_database_name
Step 3: Show the collections
show collections
This will list all the collections in your selected database.
Step 4: See all the data
db.collection_name.find()
or
db.collection_name.find().pretty()
Ok, I've worked it out
element.style.opacity = parseFloat(element.style.opacity) + 0.1;
Should be used instead of
element.style.opacity += 0.1;
Same with
element.style.opacity = parseFloat(element.style.opacity) - 0.1;
Instead of
element.style.opacity -= 0.1;
Because opacity value is stored as string, not as float. I'm still not sure though why the addition has worked.
Here are some use full delete operations for mongodb using mongo shell
To delete particular document in collections: db.mycollection.remove( {name:"stack"} )
To delete all documents in collections: db.mycollection.remove()
To delete collection : db.mycollection.drop()
to delete database :
first go to that database by use mydb
command and then
db.dropDatabase()
directly from command prompt or blash : mongo mydb --eval "db.dropDatabase()
The main difference what i have observed was that abstract class provides us with some common behaviour implemented already and subclasses only needs to implement specific functionality corresponding to them. where as for an interface will only specify what tasks needs to be done and no implementations will be given by interface. I can say it specifies the contract between itself and implemented classes.
It has nothing to do with append
. tuple(3, 4)
all by itself raises that error.
The reason is that, as the error message says, tuple
expects an iterable argument. You can make a tuple of the contents of a single object by passing that single object to tuple. You can't make a tuple of two things by passing them as separate arguments.
Just do (3, 4)
to make a tuple, as in your first example. There's no reason not to use that simple syntax for writing a tuple.
I think the best way to secure your credential is to first think of storing the Password with encryption in the account.db file which couldn't be easily available in non rooted devices and in case of rooted device the hacker must need the key to decrypt it.
Other option is do all your authentication like the way Gmail is doing. after the first authentication with the Gmail server . you got the Auth Token that would be use in case of your password . that token would be store in plain text.this token could be false in case you change the password from Server.
the last option I'd recommend you to enable 2-Factor Authentication & create Device Specific Password for your device. After losing device, all you need is to disable that device.
Here's what I do:
Generate a hidden iFrame with the data you would like to post. Since you still control that iFrame, same origin does not apply. Then submit the form in that iFrame to the ssl page. The ssl page then redirects to a non-ssl page with status messages. You have access to the iFrame.

A very common usecase of calc is take 100% width and adding some margin around the element.
One can do so with:
@someMarginVariable = 15px;
margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);
I had the same Problem. This solution works for me.

If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
You must analyse the actual HTML output, for the hint.
By giving the path like this means "from current location", on the other hand if you start with a /
that would mean "from the context".
This is the resolution of the screen that the given component is currently assigned (something like most part of the root window is visible on that screen).
public Rectangle getCurrentScreenBounds(Component component) {
return component.getGraphicsConfiguration().getBounds();
}
Usage:
Rectangle currentScreen = getCurrentScreenBounds(frameOrWhateverComponent);
int currentScreenWidth = currentScreen.width // current screen width
int currentScreenHeight = currentScreen.height // current screen height
// absolute coordinate of current screen > 0 if left of this screen are further screens
int xOfCurrentScreen = currentScreen.x
If you want to respect toolbars, etc. you'll need to calculate with this, too:
GraphicsConfiguration gc = component.getGraphicsConfiguration();
Insets screenInsets = Toolkit.getDefaultToolkit().getScreenInsets(gc);
As Christian's answer with assign()
shows, there is a way to assign in the global environment. A simpler, shorter (but not better ... stick with assign) way is to use the <<-
operator, ie
a <<- "new"
inside the function.
You could also use inline blocks to avoid floating elements
<ul>
<li>
<a href="#">some item</a>
</li>
<li>
<a href="#">another item</a>
</li>
</ul>
and then style as:
li{
/* with fix for IE */
display:inline;
display:inline-block;
zoom:1;
/*
additional styles to make it look nice
*/
}
that way you wont need to float anything, eliminating the need for clearfixes

How about:
00 00 * * * every 3 days && echo test
Where every
is a script:
#!/bin/sh
case $2 in
days)
expr `date +%j` % $1 = 0 > /dev/null
;;
weeks)
expr `date +%V` % $1 = 0 > /dev/null
;;
months)
expr `date +%m` % $1 = 0 > /dev/null
;;
esac
So it runs every day.
Using */3
runs on the 3rd, 6th, ... 27th, 30th of the month, but is then wrong after a month has a 31st day. The every
script is only wrong after the end of the year.
I was facing a problem like this, and had the idea of simply changing the innerHTML of the problematic object's children.
adiv.innerHTML = "<div...> the original html that js uses </div>";
Seems dirty, but it saved my life, as it works!
In C++11 you could also create an alias for convenience:
template<class T> using min_heap = priority_queue<T, std::vector<T>, std::greater<T>>;
And use it like this:
min_heap<int> my_heap;
<?php
$query = "select username from users";
$res = mysqli_query($connection, $query);
?>
<form>
<select>
<?php
while ($row = $res->fetch_assoc())
{
echo '<option value=" '.$row['id'].' "> '.$row['name'].' </option>';
}
?>
</select>
</form>
Use an relative path to the root of your site, for example:

If we take the problem as "how to make singleton with state", then it is not necessary to pass the state as constructor parameter. I agree with the posts that initialize the states or using set method after getting the singleton instance.
Another question is: is it good to have singleton with state?

Try this using list comprehension:

Your this
doesn't refer to the element in the step callback, instead you want to keep a reference to it at the beginning of your function (wrapped in $this
in my example):
$('.Count').each(function () {
var $this = $(this);
jQuery({ Counter: 0 }).animate({ Counter: $this.text() }, {
duration: 1000,
easing: 'swing',
step: function () {
$this.text(Math.ceil(this.Counter));
}
});
});
Update: If you want to display decimal numbers, then instead of rounding the value with Math.ceil
you can round up to 2 decimals for instance with value.toFixed(2)
:
step: function () {
$this.text(this.Counter.toFixed(2));
}
Please run the below query, it doesn't requires STUFF and GROUP BY in your case:

FROM dbo.maskdetails T
WHERE A.maskid = T.maskid
FOR XML PATH(''))as varchar(max)) as maskdetail
FROM dbo.tblmask A
JOIN dbo.school B ON B.ID = A.schoolid
This question is confusing. A regular object, {}
doesn't have a length
property unless you're intending to make your own function constructor which generates custom objects which do have it ( in which case you didn't specify ).
Meaning, you have to get the "length" by a for..in
statement on the object, since length
is not set, and increment a counter.
I'm confused as to why you need the length
. Are you manually setting 0
on the object, or are you relying on custom string keys? eg obj['foo'] = 'bar';
. If the latter, again, why the need for length?
Edit #1: Why can't you just do this?
list = [ {name:'john'}, {name:'bob'} ];
Then iterate over list? The length
is already set.

return;

Here is a full project with example:
The discussion I had with Asaph may be unclear to follow as we went back and forth quite a bit.
I thought that I might clarify the upshot of our discourse for others who might face similar situations in the future to benefit from:
ENUM
-type columns are very difficult beasts to manipulate. I wanted to add two countries (Malaysia & Sweden) to the existing set of countries in my ENUM.
It seems that MySQL 5.1 (which is what I am running) can only update the ENUM by redefining the existing set in addition to what I want:
This did not work:
ALTER TABLE carmake CHANGE country country ENUM('Sweden','Malaysia') DEFAULT NULL;
The reason was that the MySQL statement was replacing the existing ENUM with another containing the entries 'Malaysia'
and 'Sweden'
only. MySQL threw up an error because the carmake
table already had values like 'England'
and 'USA'
which were not part of the new ENUM
's definition.
Surprisingly, the following did not work either:
ALTER TABLE carmake CHANGE country country ENUM('Australia','England','USA'...'Sweden','Malaysia') DEFAULT NULL;
It turns out that even the order of elements of the existing ENUM
needs to be preserved while adding new members to it. So if my existing ENUM
looks something like ENUM('England','USA')
, then my new ENUM
has to be defined as ENUM('England','USA','Sweden','Malaysia')
and not ENUM('USA','England','Sweden','Malaysia')
. This problem only becomes manifest when there are records in the existing table that use 'USA'
or 'England'
values.
BOTTOM LINE:
Only use ENUM
s when you do not expect your set of members to change once defined. Otherwise, lookup tables are much easier to update and modify.
export const users = require('../data'); // presumes @types/node are installed
const foundUser = users.find(user => user.id === 42);
// error: Parameter 'user' implicitly has an 'any' type.ts(7006)
--resolveJsonModule
--resolveJsonModule
compiler option:
import users from "./data.json" // `import` instead of `require`
const foundUser = users.find(user => user.id === 42); // user is strongly typed, no `any`!
There are some alternatives for other cases than static JSON import.
type User = { id: number; name: string /* and others */ }
const foundUser = users.find((user: User) => user.id === 42)
function isUserArray(maybeUserArr: any): maybeUserArr is Array<User> {
return Array.isArray(maybeUserArr) && maybeUserArr.every(isUser)
}
function isUser(user: any): user is User {
return "id" in user && "name" in user
}
if (isUserArray(users)) {
const foundUser = users.find((user) => user.id === 42)
}
You can even switch to assertion functions (TS 3.7+) to get rid of if
and throw an error instead.
function assertIsUserArray(maybeUserArr: any): asserts maybeUserArr is Array<User> {
if(!isUserArray(maybeUserArr)) throw Error("wrong json type")
}
assertIsUserArray(users)
const foundUser = users.find((user) => user.id === 42) // works
A runtime type check library like io-ts
or ts-runtime
can be integrated for more complex cases.
noImplicitAny: false
undermines many useful checks of the type system:
function add(s1, s2) { // s1,s2 implicitely get `any` type
return s1 * s2 // `any` type allows string multiplication and all sorts of types :(
}
add("foo", 42)
Also better provide an explicit User
type for user
. This will avoid propagating any
to inner layer types. Instead typing and validating is kept in the JSON processing code of the outer API layer.

I encountered this issue by putting a XML file into the src/main/resources
wrongly, I deleted it and then all back to normal.
If you have Resharper (plugin) installed, you can access a feature that allows you to analyze used references via Solution Explorer > (right click) References > Optimize References...
http://www.jetbrains.com/resharper/webhelp/Refactorings__Remove_Unused_References.html
This feature does not correctly handle:
also you can try the following.
find . -name '*.java' -exec grep "<yourword" /dev/null {} \;
It gets all the files with .java extension and searches 'yourword' in each file, if it presents, it lists the file.

To update this for Python-3 you can do this
"{} {}".format(True, False)
However if you want to actually format the string (e.g. add white space), you encounter Python casting the boolean into the underlying C value (i.e. an int), e.g.
>>> "{:<8} {}".format(True, False)
'1 False'
To get around this you can cast True
as a string, e.g.
>>> "{:<8} {}".format(str(True), False)
'True False'
They both take a function from the type of the optional to something.
map()
applies the function "as is" on the optional you have:
if (optional.isEmpty()) return Optional.empty();
else return Optional.of(f(optional.get()));
What happens if your function is a function from T -> Optional<U>
?
Your result is now an Optional<Optional<U>>
!
That's what flatMap()
is about: if your function already returns an Optional
, flatMap()
is a bit smarter and doesn't double wrap it, returning Optional<U>
.
It's the composition of two functional idioms: map
and flatten
.
If you are a windows user and using python 3, then this post will help you to do parallel programming in python.when you run a usual multiprocessing library's pool programming, you will get an error regarding the main function in your program. This is because the fact that windows has no fork() functionality. The below post is giving a solution to the mentioned problem .
http://python.6.x6.nabble.com/Multiprocessing-Pool-woes-td5047050.html
Since I was using the python 3, I changed the program a little like this:
from types import FunctionType
import marshal
def _applicable(*args, **kwargs):
name = kwargs['__pw_name']
code = marshal.loads(kwargs['__pw_code'])
gbls = globals() #gbls = marshal.loads(kwargs['__pw_gbls'])
defs = marshal.loads(kwargs['__pw_defs'])
clsr = marshal.loads(kwargs['__pw_clsr'])
fdct = marshal.loads(kwargs['__pw_fdct'])
func = FunctionType(code, gbls, name, defs, clsr)
func.fdct = fdct
del kwargs['__pw_name']
del kwargs['__pw_code']
del kwargs['__pw_defs']
del kwargs['__pw_clsr']
del kwargs['__pw_fdct']
return func(*args, **kwargs)
def make_applicable(f, *args, **kwargs):
if not isinstance(f, FunctionType): raise ValueError('argument must be a function')
kwargs['__pw_name'] = f.__name__ # edited
kwargs['__pw_code'] = marshal.dumps(f.__code__) # edited
kwargs['__pw_defs'] = marshal.dumps(f.__defaults__) # edited
kwargs['__pw_clsr'] = marshal.dumps(f.__closure__) # edited
kwargs['__pw_fdct'] = marshal.dumps(f.__dict__) # edited
return _applicable, args, kwargs
def _mappable(x):
x,name,code,defs,clsr,fdct = x
code = marshal.loads(code)
gbls = globals() #gbls = marshal.loads(gbls)
defs = marshal.loads(defs)
clsr = marshal.loads(clsr)
fdct = marshal.loads(fdct)
func = FunctionType(code, gbls, name, defs, clsr)
func.fdct = fdct
return func(x)
def make_mappable(f, iterable):
if not isinstance(f, FunctionType): raise ValueError('argument must be a function')
name = f.__name__ # edited
code = marshal.dumps(f.__code__) # edited
defs = marshal.dumps(f.__defaults__) # edited
clsr = marshal.dumps(f.__closure__) # edited
fdct = marshal.dumps(f.__dict__) # edited
return _mappable, ((i,name,code,defs,clsr,fdct) for i in iterable)
After this function , the above problem code is also changed a little like this:
from multiprocessing import Pool
from poolable import make_applicable, make_mappable
def cube(x):
return x**3
if __name__ == "__main__":
pool = Pool(processes=2)
results = [pool.apply_async(*make_applicable(cube,x)) for x in range(1,7)]
print([result.get(timeout=10) for result in results])
And I got the output as :
[1, 8, 27, 64, 125, 216]
I am thinking that this post may be useful for some of the windows users.
If you are using Table.query
property:
from sqlalchemy import func
Table.query.with_entities(Table.column, func.count(Table.column)).group_by(Table.column).all()
If you are using session.query()
method (as stated in miniwark's answer):
from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()
You can use method reference like this:
user.ifPresent(ClassNameWhereMethodIs::doSomethingWithUser);
Method ifPresent()
get Consumer
object as a paremeter and (from JavaDoc): "If a value is present, invoke the specified consumer with the value." Value it is your variable user
.
Or if this method doSomethingWithUser
is in the User
class and it is not static
, you can use method reference like this:
user.ifPresent(this::doSomethingWithUser);
if "allow zero datetime=true" is not working then use the following sollutions:-
Add this to your connection string: "allow zero datetime=no" - that made the type cast work perfectly.
Generetic Action Sheet working for Swift 4, 4.2, 5
If you like a generic version that you can call from every ViewController
and in every project try this one:
class Alerts {
static func showActionsheet(viewController: UIViewController, title: String, message: String, actions: [(String, UIAlertActionStyle)], completion: @escaping (_ index: Int) -> Void) {
let alertViewController = UIAlertController(title: title, message: message, preferredStyle: .actionSheet)
for (index, (title, style)) in actions.enumerated() {
let alertAction = UIAlertAction(title: title, style: style) { (_) in
completion(index)
}
alertViewController.addAction(alertAction)
}
viewController.present(alertViewController, animated: true, completion: nil)
}
}
Call like this in your ViewController.
var actions: [(String, UIAlertActionStyle)] = []
actions.append(("Action 1", UIAlertActionStyle.default))
actions.append(("Action 2", UIAlertActionStyle.destructive))
actions.append(("Action 3", UIAlertActionStyle.cancel))
//self = ViewController
Alerts.showActionsheet(viewController: self, title: "D_My ActionTitle", message: "General Message in Action Sheet", actions: actions) { (index) in
print("call action \(index)")
/*
results
call action 0
call action 1
call action 2
*/
}
Attention: Maybe you're wondering why I add Action 1/2/3
but got results like 0,1,2. In the line for (index, (title, style)) in actions.enumerated()
I get the index of actions. Arrays always begin with the index 0. So the completion is 0,1,2.
If you like to set a enum, an id or another identifier I would recommend to hand over an object in parameter actions
.
int rgb = ((r&0x0ff)<<16)|((g&0x0ff)<<8)|(b&0x0ff);
If you know that your r, g, and b values are never > 255 or < 0 you don't need the &0x0ff
Additionaly
int red = (rgb>>16)&0x0ff;
int green=(rgb>>8) &0x0ff;
int blue= (rgb) &0x0ff;
No need for multipling.
It took me a lot of time to figure out, but finally here is a simple way to list contents of a subfolder in S3 bucket using boto3. Hope it helps
prefix = "folderone/foldertwo/"
s3 = boto3.resource('s3')
bucket = s3.Bucket(name="bucket_name_here")
FilesNotFound = True
for obj in bucket.objects.filter(Prefix=prefix):
print('{0}:{1}'.format(bucket.name, obj.key))
FilesNotFound = False
if FilesNotFound:
print("ALERT", "No file in {0}/{1}".format(bucket, prefix))
There is a default util in android SDK: http://developer.android.com/reference/android/util/TypedValue.html
float resultPix = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,1,getResources().getDisplayMetrics())
You can use pandas.Series.tolist
e.g.:
import pandas as pd
df = pd.DataFrame({'a':[1,2,3], 'b':[4,5,6]})
Run:
>>> df['a'].tolist()
You will get
>>> [1, 2, 3]
If you want to (easily) change the author for the current branch I would use something like this:
# update author for everything since origin/master
git rebase \
-i origin/master \
--exec 'git commit --amend --no-edit --author="Author Name <[email protected]>"'
I think you may be after

sum(case when Priority = 1 then 1 else 0 end) as priority1,
sum(case when Priority = 2 then 1 else 0 end) as priority2,
sum(case when Priority = 3 then 1 else 0 end) as priority3,
sum(case when Priority = 4 then 1 else 0 end) as priority4,
sum(case when Priority = 5 then 1 else 0 end) as priority5
from
Jobs
group by
jobID, JobName
However I am uncertain if you need to the jobID and JobName in your results if so remove them and remove the group by,
I too have struggled a bit with bad performance in Visual Studio 2013 (Premium). Pretty much the same issues as TS had. Slow navigation, scrolling, building... just about everything. Luckily I have manage to solve my own problem by disabling Synchronized Settings in Visual Studio. Go to menu Tools → Options → Environment-Synchronized Settings and remove this option by unchecking the checkbox.
Every call to the Iterator.next()
moves the iterator to the next element. If you want to use the current element in more than one statement or expression, you have to store it in a local variable. Or even better, why don't you simply use a for-each loop?
for (String key : map.keySet()) {
System.out.println(key + ":" + map.get(key));
}
Moreover, loop over the entrySet is faster, because you don't query the map twice for each key. Also Map.Entry
implementations usually implement the toString()
method, so you don't have to print the key-value pair manually.
for (Entry<String, Integer> entry : map.entrySet()) {
System.out.println(entry);
}
It seems the button you are invoking is not in the layout you are using in setContentView(R.layout.your_layout)

Here are the differences that can help you understand the advantages of persist and save methods:
The persist() method doesn’t guarantee that the identifier value will be assigned to the persistent state immediately, the assignment might happen at flush time.
The persist() method will not execute an insert query if it is called outside of transaction boundaries. While, the save() method returns an identifier so that an insert query is executed immediately to get the identifier, no matter if it are inside or outside of a transaction.
The persist method is called outside of transaction boundaries, it is useful in long-running conversations with an extended Session context. On the other hand save method is not good in a long-running conversation with an extended Session context.
Fifth difference between save and persist method in Hibernate: persist is supported by JPA, while save is only supported by Hibernate.
You can see the full working example from the post Difference between save and persist method in Hibernate
I know this is an old question but the most up to date answer is to use the Android Support Design library that will make your life easy.
this prototype:
int execlp(const char *file, const char *arg, ...);
Says that execlp ìs a variable argument function. It takes 2 const char *
. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char *
- all these are C strings (and the last argument must be a NULL pointer)
So, the file
argument is the path name of an executable file to be executed. arg
is the string we want to appear as argv[0]
in the executable. By convention, argv[0]
is just the file name of the executable, normally it's set to the same as file
.
The ...
are now the additional arguments to give to the executable.
Say you run this from a commandline/shell:
$ ls
That'd be execlp("ls", "ls", (char *)NULL);
Or if you run
$ ls -l /
That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);
So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);
Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:
$ ls -l /bin/??
Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.
What you want to run is:
$ /bin/sh -c "ls -l /bin/??"
This becomes
execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);
Side note:
The /bin/??
is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did
execlp("ls","ls", "-l", "/bin/??", (char *)NULL);
Probably nothing would happen (unless there's a file actually named /bin/??
) as there's no shell that interprets and expands /bin/??
Use a binding, like in this example:
<a href="#new-search" data-bind="click:SearchManager.bind($data,'1')">
Search Manager
</a>
var ViewModelStructure = function () {
var self = this;
this.SearchManager = function (search) {
console.log(search);
};
}();
As others have answered, there is no current way to add maxlength directly to a CSS class.
However, this creative solution can achieve what you are looking for.
I have the jQuery in a file named maxLengths.js which I reference in site (site.master for ASP)
run the snippet to see it in action, works well.
jquery, css, html:
$(function () {_x000D_
$(".maxLenAddress1").keypress(function (event) {_x000D_
_x000D_
if ($(this).val().length == 5) { /* obv 5 is too small for an address field, just want to use as an example though */_x000D_
return false;_x000D_
} else {_x000D_
return true;_x000D_
}_x000D_
_x000D_
});_x000D_
});
_x000D_
.maxLenAddress1{} /* this is here mostly for intellisense usage, but can be altered if you like */
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="text" class="maxLenAddress1" />
_x000D_
The advantage of using this: if it is decided the max length for this type of field needs to be pushed out or in across your entire application you can change it in one spot. Comes in handy for field lengths for things like customer codes, full name fields, email fields, any field common across your application.
You can use ymd
from lubridate
lubridate::ymd(v)
#[1] "2008-11-01"
Or anytime::anydate
anytime::anydate(v)
#[1] "2008-11-01"
sass --watch a.scss:a.css --style compressed
Consult the documentation for updates:
Turns out the binding of style to a string doesn't work. The solution would be to bind the background of the style.
<div class="circle" [style.background]="color">
this worked for me to solve the problem in IE8:
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=1)";

var newData = [1,2,3,4,5,6,7];
var chart = $('#chartjs').highcharts();
chart.series[0].setData(newData, true);
Explanation:
Variable newData
contains value that want to update in chart. Variable chart
is an object of a chart. setData
is a method provided by highchart to update data.
Method setData contains two parameters, in first parameter we need to pass new value as array and second param is Boolean value. If true
then chart updates itself and if false
then we have to use redraw()
method to update chart (i.e chart.redraw();
)

This turned out to be very flexible and extensible. $field =~ s/[^\x00-\x7F]//g ; # thus all non ASCII or specific items in question could be cleaned. Very nice either in selection or pre-processing of items that will eventually become hash keys.

I was getting this error when using Laravel and eloquent, trying to make a foreign key link would cause a 1452. The problem was lack of data in the linked table.

According to others said, you cannot instantiate from abstract class. but it exist 2 way to use it. 1. make another non-abstact class that extends from abstract class. So you can instantiate from new class and use the attributes and methods in abstract class.
public class MyCustomClass extends YourAbstractClass {
/// attributes, methods ,...
}
Rather than the command "python", consider launching Python via the py launcher, as described in sg7's answer, which by runs your latest version of Python (or lets you select a specific version). The py launcher is enabled via a check box during installation (default: "on").
Nevertheless, you can still put the "python" command in your PATH, either at "first installation" or by "modifying" an existing installation.
First Installation:
Checking the "[x] Add Python x.y to PATH" box on the very first dialog. Here's how it looks in version 3.8:
This has the effect of adding the following to the PATH
variable:
C:\Users\...\AppData\Local\Programs\Python\Python38-32\Scripts\
C:\Users\...\AppData\Local\Programs\Python\Python38-32\
Modifying an Existing Installation:
Re-run your installer (e.g. in Downloads, python-3.8.4.exe) and Select "Modify". Check all the optional features you want (likely no changes), then click [Next]. Check [x] "Add Python to environment variables", and [Install].
You may put some text in the search and filter out the Logcat result.
That was the reason for my problem :)
It might be cleaner if you have a function, say called vprint
, that checks the verbose flag for you. Then you just call your own vprint
function any place you want optional verbosity.
pyplot
is a sub-module of matplotlib
which doesn't get imported with a simple import matplotlib
.
>>> import matplotlib
>>> print matplotlib.pyplot
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
>>> import matplotlib.pyplot
>>>
It seems customary to do: import matplotlib.pyplot as plt
at which time you can use the various functions and classes it contains:
p = plt.plot(...)
Here is a CSV action result I wrote that takes a DataTable and converts it into CSV. You can return this from your view and it will prompt the user to download the file. You should be able to convert this easily into a List compatible form or even just put your list into a DataTable.

The way you are using await/async is poor at best, and it makes it hard to follow. You are mixing await
with Task'1.Result
, which is just confusing. However, it looks like you are looking at a final task result, rather than the contents.
I've rewritten your function and function call, which should fix your issue:
async Task<string> GetResponseString(string text)
{
var httpClient = new HttpClient();
var parameters = new Dictionary<string, string>();
parameters["text"] = text;
var response = await httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters));
var contents = await response.Content.ReadAsStringAsync();
return contents;
}
And your final function call:
Task<string> result = GetResponseString(text);
var finalResult = result.Result;
Or even better:
var finalResult = await GetResponseString(text);
For Jackson to serialize that class, the SomeString
field needs to either be public
(right now it's package level isolation) or you need to define getter and setter methods for it.
Instead of [ngIf] you should use *ngIf like this:
<div *ngIf="isAuth" id="sidebar">
You can also use the box-shadow property to simulate an underline.
Here is a fiddle. The idea is to use two layered box shadows to position the line in the same place as an underline.
a.underline {
text-decoration: none;
box-shadow: inset 0 -4px 0 0 rgba(255, 255, 255, 1), inset 0 -5px 0 0 rgba(255, 0, 0, 1);
}

If someone is facing issue using texttocolumns function in UFT. Please try using below function.

objRange.TextToColumns objRange2,1,1, , , , true
Here we are using coma(,) as delimiter.
here is my methods, it is a little bit convince that number of bytes fixed
private void printByte(int value) {

System.out.println(currentBinary.substring(currentBinary.length() - 8));
}
public int binaryToInteger(String binary) {
char[] numbers = binary.toCharArray();
int result = 0;
for(int i=numbers.length - 1; i>=0; i--)
if(numbers[i]=='1')
result += Math.pow(2, (numbers.length-i - 1));

After trying to use the MAVEN_OPTS variable with no luck, I came across this site which worked for me. So all I had to do was add -Xms128m -Xmx1024m to the default VM options and it worked.
To change those in Eclipse, go to Window -> Preferences -> Java -> Installed JREs. Select the checked JRE/JDK and click edit.
.outside {
width: 200px;
height: 200px;
background-color: #EEE; /*to make it visible*/
}
Needs to be
.outside {
position: relative;
width: 200px;
height: 200px;
background-color: #EEE; /*to make it visible*/
}
Absolute positioning looks for the nearest relatively positioned parent within the DOM, if one isn't defined it will use the body.
You can also do this with ant contrib's if task.
<if>
<equals arg1="${condition}" arg2="true"/>
<then>
<copy file="${some.dir}/file" todir="${another.dir}"/>
</then>
<elseif>
<equals arg1="${condition}" arg2="false"/>
<then>
<copy file="${some.dir}/differentFile" todir="${another.dir}"/>
</then>
</elseif>
<else>
<echo message="Condition was neither true nor false"/>
</else>
</if>
If you could use MariaDB there is a very very easy solution.
Since MariaDB-10.02 there has been added a new storage engine called CONNECT that can help us to convert the results of another query or table into a pivot table, just like what you want: You can have a look at the docs.
First of all install the connect storage engine.
Now the pivot column of our table is itemname
and the data for each item is located in itemvalue
column, so we can have the result pivot table using this query:
create table pivot_table
engine=connect table_type=pivot tabname=history
option_list='PivotCol=itemname,FncCol=itemvalue';
Now we can select what we want from the pivot_table
:
select * from pivot_table
I've been trying to run an Android Google Maps v2 under an emulator, and I found many ways to do that, but none of them worked for me. I have always this warning in the Logcat Google Play services out of date. Requires 3025100 but found 2010110
and when I want to update Google Play services on the emulator nothing happened. The problem was that the com.google.android.gms APK was not compatible with the version of the library in my Android SDK.
I installed these files "com.google.android.gms.apk", "com.android.vending.apk" on my emulator and my app Google Maps v2 worked fine. None of the other steps regarding /system/app were required.
Here you go. this should work.

Knowing the version of Windows and SQL Server might be helpful in some cases. From the Native Client 10.0 I infer either SQL Server 2008 or SQL Server 2008 R2.
There are a few possible things to check, but I would check to see if 'priority boost' was configured on the SQL Server. This is a deprecated setting and will eventually be removed. The problem is that it can rob the operating system of needed resources. See the notes at:
http://msdn.microsoft.com/en-in/library/ms180943(v=SQL.105).aspx
If 'priority boost' has been configured to 1, then get it configured back to 0.
exec sp_configure 'priority boost', 0;
RECONFIGURE;

They are simply called objects.
As @Alex McMillan mentioned, use state to dictate what should be rendered in the dom.
In the example below I have an input field and I want to add a second one when the user clicks the button, the onClick event handler calls handleAddSecondInput( ) which changes inputLinkClicked to true. I am using a ternary operator to check for the truthy state, which renders the second input field
class HealthConditions extends React.Component {
constructor(props) {
super(props);
this.state = {
inputLinkClicked: false
}
}
handleAddSecondInput() {
this.setState({
inputLinkClicked: true
})
}
render() {
return(
<main id="wrapper" className="" data-reset-cookie-tab>
<div id="content" role="main">
<div className="inner-block">
<H1Heading title="Tell us about any disabilities, illnesses or ongoing conditions"/>
<InputField label="Name of condition"
InputType="text"
InputId="id-condition"
InputName="condition"
/>
{
this.state.inputLinkClicked?
<InputField label=""
InputType="text"
InputId="id-condition2"
InputName="condition2"
/>
:
<div></div>
}
<button
type="button"
className="make-button-link"
data-add-button=""
href="#"
onClick={this.handleAddSecondInput}
>
Add a condition
</button>
<FormButton buttonLabel="Next"

);
}
}

If you are uploading your files through GIT from your local machine then you can use the same command you are using in your local machine while you are connected to your live server using BASH or something like.You can use this as like you use locally.
php artisan cache:clear
php artisan route:cache
It should work.
You can do it like this:
$firstday = date_create()->modify('first day January 2010');
I did it this way: Just add the event to any control, set the control's tag, and add a conditional to handle the tooltip for the appropriate control/tag.
private void Info_MouseHover(object sender, EventArgs e)
{
Control senderObject = sender as Control;
string hoveredControl = senderObject.Tag.ToString();
// only instantiate a tooltip if the control's tag contains data
if (hoveredControl != "")
{
ToolTip info = new ToolTip
{
AutomaticDelay = 500
};
string tooltipMessage = string.Empty;
// add all conditionals here to modify message based on the tag
// of the hovered control
if (hoveredControl == "save button")
{
tooltipMessage = "This button will save stuff.";
}
info.SetToolTip(senderObject, tooltipMessage);
}
}
Peer dependency warnings, more often than not, can be ignored. The only time you will want to take action is if the peer dependency is missing entirely, or if the version of a peer dependency is higher than the version you have installed.
Let's take this warning as an example:
npm WARN @angular/[email protected] requires a peer of @angular/[email protected] but none is installed. You must install peer dependencies yourself.
With Angular, you would like the versions you are using to be consistent across all packages. If there are any incompatible versions, change the versions in your package.json, and run npm install
so they are all synced up. I tend to keep my versions for Angular at the latest version, but you will need to make sure your versions are consistent for whatever version of Angular you require (which may not be the most recent).
In a situation like this:
npm WARN [email protected] requires a peer of @angular/core@^2.4.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.
If you are working with a version of Angular that is higher than 4.0.0, then you will likely have no issues. Nothing to do about this one then. If you are using an Angular version under 2.4.0, then you need to bring your version up. Update the package.json, and run npm install
, or run npm install
for the specific version you need. Like this:
npm install @angular/[email protected] --save
You can leave out the --save
if you are running npm 5.0.0 or higher, that version saves the package in the dependencies section of the package.json automatically.
In this situation:
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
You are running Windows, and fsevent requires OSX. This warning can be ignored.
Hope this helps, and have fun learning Angular!
If I were to iterate nums = [1, 2, 3, 4, 5]
I would do
for i, num in enumerate(nums, start=1):
print(i, num)
Or get the length as l = len(nums)
for i in range(l):
print(i+1, nums[i])
