i craeted an Extionclass for json :
public static class JsonExtentions
{
public static string SerializeToJson(this object SourceObject) { return Newtonsoft.Json.JsonConvert.SerializeObject(SourceObject); }
public static T JsonToObject<T>(this string JsonString) { return (T)Newtonsoft.Json.JsonConvert.DeserializeObject<T>(JsonString); }
}
Design-Pattern:
public class Myobject
{
public Myobject(){}
public string prop1 { get; set; }
public static Myobject GetObject(string JsonString){return JsonExtentions.JsonToObject<Myobject>(JsonString);}
public string ToJson(string JsonString){return JsonExtentions.SerializeToJson(this);}
}
Usage:
Myobject dd= Myobject.GetObject(jsonstring);
Console.WriteLine(dd.prop1);
Took me a while to read through the above. This was the answer for me:
import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")
g = sns.lmplot(
x="total_bill",
y="tip",
hue="smoker",
data=tips,
legend=False
)
plt.legend(title='Smoker', loc='upper left', labels=['Hell Yeh', 'Nah Bruh'])
plt.show(g)
Reference this for more arguments: matplotlib.pyplot.legend
You cannot undo the latest git add, but you can undo all add
s since the last commit. git reset
without a commit argument resets the index (unstages staged changes):
git reset
This is what i do and it's in my opinion simplest way to do this. define an object manager for your new customized model then define your model.
from django.db import models
from django.contrib.auth.models import PermissionsMixin, AbstractBaseUser, BaseUserManager
class User_manager(BaseUserManager):
def create_user(self, username, email, gender, nickname, password):
email = self.normalize_email(email)
user = self.model(username=username, email=email, gender=gender, nickname=nickname)
user.set_password(password)
user.save(using=self.db)
return user
def create_superuser(self, username, email, gender, password, nickname=None):
user = self.create_user(username=username, email=email, gender=gender, nickname=nickname, password=password)
user.is_superuser = True
user.is_staff = True
user.save()
return user
class User(PermissionsMixin, AbstractBaseUser):
username = models.CharField(max_length=32, unique=True, )
email = models.EmailField(max_length=32)
gender_choices = [("M", "Male"), ("F", "Female"), ("O", "Others")]
gender = models.CharField(choices=gender_choices, default="M", max_length=1)
nickname = models.CharField(max_length=32, blank=True, null=True)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
REQUIRED_FIELDS = ["email", "gender"]
USERNAME_FIELD = "username"
objects = User_manager()
def __str__(self):
return self.username
Dont forget to add this line of code in your settings.py
:
AUTH_USER_MODEL = 'YourApp.User'
This is what i do and it always works.
use array detect
method if you wanted to return first value where block returns true
[1,2,3,11,34].detect(&:even?) #=> 2
OR
[1,2,3,11,34].detect{|i| i.even?} #=> 2
If you wanted to return all values where block returns true then use select
[1,2,3,11,34].select(&:even?) #=> [2, 34]
As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live(). Refer: http://api.jquery.com/on/
$('#imageFile').on("change", function(){ uploadFile(); });
Best way is running Particular migration again by using down or up(in rails 4. It's change)
rails db:migrate:up VERSION=timestamp
Now how you get the timestamp. Go to this path
/db/migrate
Identify migration file you want to revert.pick the timestamp from that file name.
This isn't exactly the issue I had, but if anyone is looking to convert a BindingList of any type to List of the same type, then this is how it is done:
var list = bindingList.ToDynamicList();
Also, if you're assigning BindingLists of dynamic types to a DataGridView.DataSource, then make sure you declare it first as IBindingList so the above works.
You should only need to do a single join:
SELECT e.Grade, v.Score, e.CaseNum, e.FileNum, e.ActivityNum
FROM Evaluation e
INNER JOIN Value v ON e.CaseNum = v.CaseNum AND e.FileNum = v.FileNum AND e.ActivityNum = v.ActivityNum
If you are using bootstrap and font-awesome then it is easy, no need to write a single line of new code, just add fa-Nx, as big you want, See the demo
<span class="glyphicon glyphicon-globe"></span>
<span class="glyphicon glyphicon-globe fa-lg"></span>
<span class="glyphicon glyphicon-globe fa-2x"></span>
<span class="glyphicon glyphicon-globe fa-3x"></span>
<span class="glyphicon glyphicon-globe fa-4x"></span>
<span class="glyphicon glyphicon-globe fa-5x"></span>
I'm in a somewhat similar situation. It's not clear whether you know chunk size in bytes; I usually don't, but the number of records (lines) that is required is known:
def get_line():
with open('4gb_file') as file:
for i in file:
yield i
lines_required = 100
gen = get_line()
chunk = [i for i, j in zip(gen, range(lines_required))]
Update: Thanks nosklo. Here's what I meant. It almost works, except that it loses a line 'between' chunks.
chunk = [next(gen) for i in range(lines_required)]
Does the trick w/o losing any lines, but it doesn't look very nice.
This kind of code perhaps should work for You
SELECT
*,
CASE
WHEN (pvc IS NULL OR pvc = '') AND (datepose < 1980) THEN '01'
WHEN (pvc IS NULL OR pvc = '') AND (datepose >= 1980) THEN '02'
WHEN (pvc IS NULL OR pvc = '') AND (datepose IS NULL OR datepose = 0) THEN '03'
ELSE '00'
END AS modifiedpvc
FROM my_table;
gid | datepose | pvc | modifiedpvc
-----+----------+-----+-------------
1 | 1961 | 01 | 00
2 | 1949 | | 01
3 | 1990 | 02 | 00
1 | 1981 | | 02
1 | | 03 | 00
1 | | | 03
(6 rows)
You do not need to pass the size parameter, just declare Varchar
already understands that it is MAX like:
cmd.Parameters.Add("@blah",SqlDbType.VarChar).Value = "some large text";
If the column is already populated with data and live in production, I'd recommend a step by step approach, so as to avoid downtime in production while waiting for the migrations.
First I'd create a db migration to add columns with the new name(s) and populate them with the values from the old column name.
class AddCorrectColumnNames < ActiveRecord::Migration
def up
add_column :table, :correct_name_column_one, :string
add_column :table, :correct_name_column_two, :string
puts 'Updating correctly named columns'
execute "UPDATE table_name SET correct_name_column_one = old_name_column_one, correct_name_column_two = old_name_column_two"
end
end
def down
remove_column :table, :correct_name_column_one
remove_column :table, :correct_name_column_two
end
end
Then I'd commit just that change, and push the change into production.
git commit -m 'adding columns with correct name'
Then once the commit has been pushed into production, I'd run.
Production $ bundle exec rake db:migrate
Then I'd update all of the views/controllers that referenced the old column name to the new column name. Run through my test suite, and commit just those changes. (After making sure it was working locally and passing all tests first!)
git commit -m 'using correct column name instead of old stinky bad column name'
Then I'd push that commit to production.
At this point you can remove the original column without worrying about any sort of downtime associated with the migration itself.
class RemoveBadColumnNames < ActiveRecord::Migration
def up
remove_column :table, :old_name_column_one
remove_column :table, :old_name_column_two
end
def down
add_column :table, :old_name_column_one, :string
add_column :table, :old_name_column_two, :string
end
end
Then push this latest migration to production and run bundle exec rake db:migrate
in the background.
I realize this is a bit more involved of a process, but I'd rather do this than have issues with my production migration.
If you install MySQL via homebrew on MacOS, you might need to delete your old data directory /usr/local/var/mysql

Try
public bool IsDivisible(int x, int n)
{
return (x % n) == 0;
}
The modulus operator % returns the remainder after dividing x by n which will always be 0 if x is divisible by n.
For more information, see the % operator on MSDN.
I made a tuple implementation that works quite well. This solution allows for array destructuring, as well as basic type-cheking.
const Tuple = (function() {
function Tuple() {
// Tuple needs at least one element
if (arguments.length < 1) {
throw new Error('Tuple needs at least one element');
}
const args = { ...arguments };
// Define a length property (equal to the number of arguments provided)
Object.defineProperty(this, 'length', {
value: arguments.length,
writable: false
});
// Assign values to enumerable properties
for (let i in args) {
Object.defineProperty(this, i, {
enumerable: true,
get() {
return args[+i];
},
// Checking if the type of the provided value matches that of the existing value
set(value) {
if (typeof value !== typeof args[+i]) {
throw new Error('Cannot assign ' + typeof value + ' on ' + typeof args[+i]);
}
args[+i] = value;
}
});
}
// Implementing iteration with Symbol.iterator (allows for array destructuring as well for...of loops)
this[Symbol.iterator] = function() {
const tuple = this;
return {
current: 0,
last: tuple.length - 1,
next() {
if (this.current <= this.last) {
let val = { done: false, value: tuple[this.current] };
this.current++;
return val;
} else {
return { done: true };
}
}
};
};
// Sealing the object to make sure no more values can be added to tuple
Object.seal(this);
}
// check if provided object is a tuple
Tuple.isTuple = function(obj) {
return obj instanceof Tuple;
};
// Misc. for making the tuple more readable when printing to the console
Tuple.prototype.toString = function() {
const copyThis = { ...this };
const values = Object.values(copyThis);
return `(${values.join(', ')})`;
};
// conctat two instances of Tuple
Tuple.concat = function(obj1, obj2) {
if (!Tuple.isTuple(obj1) || !Tuple.isTuple(obj2)) {
throw new Error('Cannot concat Tuple with ' + typeof (obj1 || obj2));
}
const obj1Copy = { ...obj1 };
const obj2Copy = { ...obj2 };
const obj1Items = Object.values(obj1Copy);
const obj2Items = Object.values(obj2Copy);
return new Tuple(...obj1Items, ...obj2Items);
};
return Tuple;
})();
const SNAKE_COLOR = new Tuple(0, 220, 10);
const [red, green, blue] = SNAKE_COLOR;
console.log(green); // => 220
If you're using @ConfigurationProperties
with Spring Boot 2 to inject maps with keys that contain colons then you need an additional level of escaping using square brackets inside the quotes because spring only allows alphanumeric and '-' characters, stripping out the rest. Your new key would look like this:
"[8.11.32.120:8000]": GoogleMapsKeyforThisDomain
See this github issue for reference.
After many fruitful hours of exploring OCR libraries, bounding boxes and clustering algorithms - I found a solution so simple it makes you want to cry!
I hope you are using Linux;
pdftotext -layout NAME_OF_PDF.pdf
AMAZING!!
Now you have a nice text file with all the information lined up in nice columns, now it is trivial to format into a csv etc..
It is for times like this that I love Linux, these guys came up with AMAZING solutions to everything, and put it there for FREE!

You just add one additional row before you execute the loop. This row contains your CSV file header name.
schema = ['a','b','c','b']
row = 4
generators = ['A','B','C','D']
with open('test.csv','wb') as csvfile:
writer = csv.writer(csvfile, delimiter=delimiter)
# Gives the header name row into csv
writer.writerow([g for g in schema])
#Data add in csv file
for x in xrange(rows):
writer.writerow([g() for g in generators])
You can set the path variable for easily by command prompt.
Open run and write cmd
In the command window write the following: set path=%path%;C:\python36
pip is installed by default when we install Python in windows.
After setting up the environment variables path for python executables, we can run python interpreter from the command line on windows CMD
After that, we can directly use the python command with pip option to install further packages as following:-
C:\ python -m pip install python_module_name
This will install the module using pip.
From Google Code FAQ - Creating a Store Locator with PHP, MySQL & Google Maps:
Here's the SQL statement that will find the closest 20 locations that are within a radius of 25 miles to the 37, -122 coordinate. It calculates the distance based on the latitude/longitude of that row and the target latitude/longitude, and then asks for only rows where the distance value is less than 25, orders the whole query by distance, and limits it to 20 results. To search by kilometers instead of miles, replace 3959 with 6371.
SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) )
* cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin(radians(lat)) ) ) AS distance
FROM markers
HAVING distance < 25
ORDER BY distance
LIMIT 0 , 20;
Versions of sed
that support the -i
option for editing a file in place write to a temporary file and then rename the file.
Alternatively, you can just use ed
. For example, to change all occurrences of foo
to bar
in the file file.txt
, you can do:
echo ',s/foo/bar/g; w' | tr \; '\012' | ed -s file.txt
Syntax is similar to sed
, but certainly not exactly the same.
Even if you don't have a -i
supporting sed
, you can easily write a script to do the work for you. Instead of sed -i 's/foo/bar/g' file
, you could do inline file sed 's/foo/bar/g'
. Such a script is trivial to write. For example:
#!/bin/sh
IN=$1
shift
trap 'rm -f "$tmp"' 0
tmp=$( mktemp )
<"$IN" "$@" >"$tmp" && cat "$tmp" > "$IN" # preserve hard links
should be adequate for most uses.
The tibble
package has a function enframe()
that solves this problem by coercing nested list
objects to nested tibble
("tidy" data frame) objects. Here's a brief example from R for Data Science:
x <- list(
a = 1:5,
b = 3:4,
c = 5:6
)
df <- enframe(x)
df
#> # A tibble: 3 × 2
#> name value
#> <chr> <list>
#> 1 a <int [5]>
#> 2 b <int [2]>
#> 3 c <int [2]>
Since you have several nests in your list, l
, you can use the unlist(recursive = FALSE)
to remove unnecessary nesting to get just a single hierarchical list and then pass to enframe()
. I use tidyr::unnest()
to unnest the output into a single level "tidy" data frame, which has your two columns (one for the group name
and one for the observations with the groups value
). If you want columns that make wide, you can add a column using add_column()
that just repeats the order of the values 132 times. Then just spread()
the values.
library(tidyverse)
l <- replicate(
132,
list(sample(letters, 20)),
simplify = FALSE
)
l_tib <- l %>%
unlist(recursive = FALSE) %>%
enframe() %>%
unnest()
l_tib
#> # A tibble: 2,640 x 2
#> name value
#> <int> <chr>
#> 1 1 d
#> 2 1 z
#> 3 1 l
#> 4 1 b
#> 5 1 i
#> 6 1 j
#> 7 1 g
#> 8 1 w
#> 9 1 r
#> 10 1 p
#> # ... with 2,630 more rows
l_tib_spread <- l_tib %>%
add_column(index = rep(1:20, 132)) %>%
spread(key = index, value = value)
l_tib_spread
#> # A tibble: 132 x 21
#> name `1` `2` `3` `4` `5` `6` `7` `8` `9` `10` `11`
#> * <int> <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr>
#> 1 1 d z l b i j g w r p y
#> 2 2 w s h r i k d u a f j
#> 3 3 r v q s m u j p f a i
#> 4 4 o y x n p i f m h l t
#> 5 5 p w v d k a l r j q n
#> 6 6 i k w o c n m b v e q
#> 7 7 c d m i u o e z v g p
#> 8 8 f s e o p n k x c z h
#> 9 9 d g o h x i c y t f j
#> 10 10 y r f k d o b u i x s
#> # ... with 122 more rows, and 9 more variables: `12` <chr>, `13` <chr>,
#> # `14` <chr>, `15` <chr>, `16` <chr>, `17` <chr>, `18` <chr>,
#> # `19` <chr>, `20` <chr>
You can also use Index.set_names
as follows:
In [25]: x = pd.DataFrame({'year':[1,1,1,1,2,2,2,2],
....: 'country':['A','A','B','B','A','A','B','B'],
....: 'prod':[1,2,1,2,1,2,1,2],
....: 'val':[10,20,15,25,20,30,25,35]})
In [26]: x = x.set_index(['year','country','prod']).squeeze()
In [27]: x
Out[27]:
year country prod
1 A 1 10
2 20
B 1 15
2 25
2 A 1 20
2 30
B 1 25
2 35
Name: val, dtype: int64
In [28]: x.index = x.index.set_names('foo', level=1)
In [29]: x
Out[29]:
year foo prod
1 A 1 10
2 20
B 1 15
2 25
2 A 1 20
2 30
B 1 25
2 35
Name: val, dtype: int64
To solve the issue try to repair the .net framework 4 and then run the command
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
Because they do not use the SQL import wizard, the steps would be as follows:
Right click on the database in the option tasks to import data,
Once the wizard is open, we select the type of data to be implied. In this case it would be the
Flat file source
We select the CSV file, you can configure the data type of the tables in the CSV, but it is best to bring it from the CSV.
SQL client
Depending on our type of authentication we select it, once this is done, a very important option comes.
Enable id insert
(usually not starting from 1), instead if we have a column with the id in the CSV we select the enable id insert, the next step is to end the wizard, we can review the changes here.
On the other hand, in the following window may come alerts, or warnings the ideal is to ignore this, only if they leave error is necessary to pay attention.
Unique is a keyword used in the Create Table() directive to denote that a field will contain unique data, usually used for natural keys, foreign keys etc.
For example:
Create Table Employee(
Emp_PKey Int Identity(1, 1) Constraint PK_Employee_Emp_PKey Primary Key,
Emp_SSN Numeric Not Null Unique,
Emp_FName varchar(16),
Emp_LName varchar(16)
)
i.e. Someone's Social Security Number would likely be a unique field in your table, but not necessarily the primary key.
Distinct is used in the Select statement to notify the query that you only want the unique items returned when a field holds data that may not be unique.
Select Distinct Emp_LName
From Employee
You may have many employees with the same last name, but you only want each different last name.
Obviously if the field you are querying holds unique data, then the Distinct keyword becomes superfluous.
Try the packaged pecl version instead (the advantage of the packaged installs is that they're easier to upgrade):
apt-get install php5-dev
pecl install pdo
pecl install pdo_pgsql
or, if you just need a driver for PHP, but that it doesn't have to be the PDO one:
apt-get install php5-pgsql
Otherwise, that message most likely means you need to install a more recent libpq package. You can check which version you have by running:
dpkg -s libpq-dev
I've collected info together:
user_link

Simplest way of doing it:
git remote rename origin repo_bitbucket
git remote add origin https://github.com/abc/repo.git
git push origin master
Once the push to GitHub is successful, delete the old remote by running:
git remote rm repo_bitbucket
Verilog thinks in bits, so reg [7:0] a[0:3]
will give you a 4x8 bit array (=4x1 byte array). You get the first byte out of this with a[0]
. The third bit of the 2nd byte is a[1][2]
.
For a 2D array of bytes, first check your simulator/compiler. Older versions (pre '01, I believe) won't support this. Then reg [7:0] a [0:3] [0:3]
will give you a 2D array of bytes. A single bit can be accessed with a[2][0][7]
for example.
reg [7:0] a [0:3];
reg [7:0] b [0:3] [0:3];
reg [7:0] c;
reg d;
initial begin
for (int i=0; i<=3; i++) begin
a[i] = i[7:0];
end
c = a[0];
d = a[1][2];
// using 2D
for (int i=0; i<=3; i++)
for (int j=0; j<=3; j++)
b[i][j] = i*j; // watch this if you're building hardware
end
Here is my solution. Just get a reference to your view and call this method:
public static void animateViewFromBottomToTop(final View view){
view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
final int TRANSLATION_Y = view.getHeight();
view.setTranslationY(TRANSLATION_Y);
view.setVisibility(View.GONE);
view.animate()
.translationYBy(-TRANSLATION_Y)
.setDuration(500)
.setStartDelay(200)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationStart(final Animator animation) {
view.setVisibility(View.VISIBLE);
}
})
.start();
}
});
}
No need to do anything else =)

In fact, I was reusing the variable and forgot to reset them inside the external loop, like the comment of John Lyon:
for ...
x_batch = []
y_batch = []
for ...
x_batch.append(one_hot(int_word, vocab_size))
y_batch.append(one_hot(int_nb, vocab_size, value))
...
...
if ...
x_batch = np.asarray(x_batch)
y_batch = np.asarray(y_batch)
...
Then, check if you are using np.asarray() or something like that.
RewriteBase
is only applied to the target of a relative rewrite rule.
Using RewriteBase like this...
RewriteBase /folder/
RewriteRule a\.html b.html
is essentially the same as...
RewriteRule a\.html /folder/b.html
But when the .htaccess file is inside /folder/
then this also points to the same target:
RewriteRule a\.html b.html
Although the docs imply always using a RewriteBase
, Apache usually detects it correctly for paths under the DocumentRoot unless:
You are using Alias
directives
You are using .htaccess rewrite rules to perform HTTP redirects (rather than just silent rewriting) to relative URLs
In these cases, you may find that you need to specify the RewriteBase.
However, since it's a confusing directive, it's generally better to simply specify absolute (aka 'root relative') URIs in your rewrite targets. Other developers reading your rules will grasp these more easily.
Quoting from Jon Lin's excellent in-depth answer here:
In an htaccess file, mod_rewrite works similar to a <Directory>
or <Location>
container. and the RewriteBase
is used to provide a relative path base.
For example, say you have this folder structure:
DocumentRoot
|-- subdir1
`-- subdir2
`-- subsubdir
So you can access:
http://example.com/
(root)http://example.com/subdir1
(subdir1)http://example.com/subdir2
(subdir2)http://example.com/subdir2/subsubdir
(subsubdir)The URI that gets sent through a RewriteRule
is relative to the directory containing the htaccess file. So if you have:
RewriteRule ^(.*)$ -
/a/b/c/d
, then the captured URI ($1
) is a/b/c/d
. subdir2
and the request is /subdir2/e/f/g
then the captured URI is e/f/g
. subsubdir
, and the request is /subdir2/subsubdir/x/y/z
, then the captured URI is x/y/z
. The directory that the rule is in has that part stripped off of the URI. The rewrite base has no affect on this, this is simply how per-directory works.
What the rewrite base does do, is provide a URL-path base (not a file-path base) for any relative paths in the rule's target. So say you have this rule:
RewriteRule ^foo$ bar.php [L]
The bar.php
is a relative path, as opposed to:
RewriteRule ^foo$ /bar.php [L]
where the /bar.php
is an absolute path. The absolute path will always be the "root" (in the directory structure above). That means that regardless of whether the rule is in the "root", "subdir1", "subsubdir", etc. the /bar.php
path always maps to http://example.com/bar.php
.
But the other rule, with the relative path, it's based on the directory that the rule is in. So if
RewriteRule ^foo$ bar.php [L]
is in the "root" and you go to http://example.com/foo
, you get served http://example.com/bar.php
. But if that rule is in the "subdir1" directory, and you go to http://example.com/subdir1/foo
, you get served http://example.com/subdir1/bar.php
. etc. This sometimes works and sometimes doesn't, as the documentation says, it's supposed to be required for relative paths, but most of the time it seems to work. Except when you are redirecting (using the R
flag, or implicitly because you have http://host
in your rule's target). That means this rule:
RewriteRule ^foo$ bar.php [L,R]
if it's in the "subdir2" directory, and you go to http://example.com/subdir2/foo
, mod_rewrite will mistake the relative path as a file-path instead of a URL-path and because of the R
flag, you'll end up getting redirected to something like: http://example.com/var/www/localhost/htdocs/subdir1
. Which is obviously not what you want.
This is where RewriteBase
comes in. The directive tells mod_rewrite what to append to the beginning of every relative path. So if I have:
RewriteBase /blah/
RewriteRule ^foo$ bar.php [L]
in "subsubdir", going to http://example.com/subdir2/subsubdir/foo
will actually serve me http://example.com/blah/bar.php
. The "bar.php" is added to the end of the base. In practice, this example is usually not what you want, because you can't have multiple bases in the same directory container or htaccess file.
In most cases, it's used like this:
RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]
where those rules would be in the "subdir1" directory and
RewriteBase /subdir2/subsubdir/
RewriteRule ^foo$ bar.php [L]
would be in the "subsubdir" directory.
This partly allows you to make your rules portable, so you can drop them in any directory and only need to change the base instead of a bunch of rules. For example if you had:
RewriteEngine On
RewriteRule ^foo$ /subdir1/bar.php [L]
RewriteRule ^blah1$ /subdir1/blah.php?id=1 [L]
RewriteRule ^blah2$ /subdir1/blah2.php [L]
...
such that going to http://example.com/subdir1/foo
will serve http://example.com/subdir1/bar.php
etc. And say you decided to move all of those files and rules to the "subsubdir" directory. Instead of changing every instance of /subdir1/
to /subdir2/subsubdir/
, you could have just had a base:
RewriteEngine On
RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]
RewriteRule ^blah1$ blah.php?id=1 [L]
RewriteRule ^blah2$ blah2.php [L]
...
And then when you needed to move those files and the rules to another directory, just change the base:
RewriteBase /subdir2/subsubdir/
and that's it.
All the validation from model are skipped when we use validate: false
user = User.new(....)
user.save(validate: false)
I'm responding to this question because I had a different way of fixing this problem than the other answers had. I had this problem when I refactored the name of the plugins that I was exporting. Eventually I had to make sure to fix/change the following.
This worked for me, but your mileage may vary.
using Newtonsoft.Json;
Class1 obj1 = new Class1();
Class2 obj2 = JsonConvert.DeserializeObject<Class2>(JsonConvert.SerializeObject(obj1));
public class Class1
{
public static explicit operator Class2(Class1 obj)
{
return JsonConvert.DeserializeObject<Class2>(JsonConvert.SerializeObject(obj));
}
}
Which then allows you to do something like
Class1 obj1 = new Class1();
Class2 obj2 = (Class2)obj1;
Use onkeypress
. Check if the pressed key is enter (keyCode = 13). if yes, call the searching()
function.
HTML
<input name="keywords" type="text" id="keywords" size="50" onkeypress="handleKeyPress(event)">
JAVASCRIPT
function handleKeyPress(e){
var key=e.keyCode || e.which;
if (key==13){
searching();
}
}
Here is a snippet showing it in action:
document.getElementById("msg1").innerHTML = "Default";_x000D_
function handle(e){_x000D_
document.getElementById("msg1").innerHTML = "Trigger";_x000D_
var key=e.keyCode || e.which;_x000D_
if (key==13){_x000D_
document.getElementById("msg1").innerHTML = "HELLO!";_x000D_
}_x000D_
}
_x000D_
<input type="text" name="box22" value="please" onkeypress="handle(event)"/>_x000D_
<div id="msg1"></div>

The following will return an ISO8601 and RFC3339-compliant UTC timestamp, including nanoseconds.
It uses strftime()
, which works with struct timespec
just as well as with struct timeval
because all it cares about is the number of seconds, which both provide. Nanoseconds are then appended (careful to pad with zeros!) as well as the UTC suffix 'Z'.
Example output: 2021-01-19T04:50:01.435561072Z
#include <stdio.h>
#include <time.h>
#include <sys/time.h>
int utc_system_timestamp(char[]);
int main(void) {
char buf[31];
utc_system_timestamp(buf);
printf("%s\n", buf);
}
// Allocate exactly 31 bytes for buf
int utc_system_timestamp(char buf[]) {
const int bufsize = 31;
struct timespec now;
struct tm tm;
int retval = clock_gettime(CLOCK_REALTIME, &now);
gmtime_r(&now.tv_sec, &tm);
strftime(buf, bufsize, "%Y-%m-%dT%H:%M:%S.", &tm);
sprintf(buf, "%s%09luZ", buf, now.tv_nsec);
return retval;
}
I know this is an old question but I just want to comment here: To any extent email addresses ARE case sensitive, most users would be "very unwise" to actively use an email address that requires capitals. They would soon stop using the address because they'd be missing a lot of their mail. (Unless they have a specific reason to make things difficult, and they expect mail only from specific senders they know.)
That's because imperfect humans as well as imperfect software exist, (Surprise!) which will assume all email is lowercase, and for this reason these humans and software will send messages using a "lower cased version" of the address regardless of how it was provided to them. If the recipient is unable to receive such messages, it won't be long before they notice they're missing a lot, and switch to a lowercase-only email address, or get their server set up to be case-insensitive.
You can also try using String Tokeniser, for any space, tab, newline, and all. A simple way is,
String s = "Your Text Here";
StringTokenizer st = new StringTokenizer( s, " " );
while(st.hasMoreTokens())
{
System.out.print(st.nextToken());
}
ALTER TABLE mytable DROP INDEX key_Name;
I didn't found any particular answer to this question but i deleted the emulator and create a new one and increase the Ram size of the new emulator.Then the emulator works fine.

In your custom cell create public method:
- (void)showSelection:(BOOL)selection
{
self.contentView.backgroundColor = selection ? [UIColor blueColor] : [UIColor white];
}
Also write redefenition of -prepareForReuse cell method:
- (void)prepareForReuse
{
[self showSelection:NO];
[super prepareForReuse];
}
And in your ViewController you should have _selectedIndexPath variable, which defined in -didSelectItemAtIndexPath and nullified in -didDeselectItemAtIndexPath
NSIndexPath *_selectedIndexPath;
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"Cell";
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
if (_selectedIndexPath) {
[cell showSelection:[indexPath isEqual:_selectedIndexPath]];
}
}
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView cellForItemAtIndexPath:indexPath];
[cell showSelection:![indexPath isEqual:_selectedIndexPath]];// on/off selection
_selectedIndexPath = [indexPath isEqual:_selectedIndexPath] ? nil : indexPath;

This approach differs from the box-shadow
effect in that it accounts for opacity and does not apply the drop shadow effect to the box but rather to the corners of the svg element itself.
Please Note: This approach only works when the class is placed on the <svg>
element alone. You can NOT use this on an inline svg element such as <rect>
.
<!-- This will NOT work! -->
<svg><rect class="shadow" ... /></svg>

Does it have something to do with preventing other events on the page from firing?
Yes.
Setting async to false means that the statement you are calling has to complete before the next statement in your function can be called. If you set async: true then that statement will begin it's execution and the next statement will be called regardless of whether the async statement has completed yet.

Running in a Docker container introduced a whole slew of additional problems for connecting so hopefully this helps someone. I ended up needed to add the following options which I'll explain below:
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=${DOCKER_HOST_IP}
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.rmi.port=9998
DOCKER_HOST_IP
Unlike using jconsole locally, you have to advertise a different IP than you'll probably see from within the container. You'll need to replace ${DOCKER_HOST_IP}
with the externally resolvable IP (DNS Name) of your Docker host.
JMX Remote & RMI Ports
It looks like JMX also requires access to a remote management interface (jstat) that uses a different port to transfer some data when arbitrating the connection. I didn't see anywhere immediately obvious in jconsole
to set this value. In the linked article the process was:
jconsole
with logging enabledjconsole
attempted to useiptables
/firewall
rules as necessary to allow that port to connectWhile that works, it's certainly not an automatable solution. I opted for an upgrade from jconsole to VisualVM since it let's you to explicitly specify the port on which jstatd
is running. In VisualVM, add a New Remote Host and update it with values that correlate to the ones specified above:
Then right-click the new Remote Host Connection and Add JMX Connection...
Don't forget to check the checkbox for Do not require SSL connection
. Hopefully, that should allow you to connect.
I also ran into this problem, and was able to work around a similar EOF error using:
read.table("....csv", sep=",", ...)
Notice that the separator parameter is defined within the more general read.table()
.

There would be a list of validators with checkbox options for Manual & Build, go and individually disable the javascript validator there.
If you select the Suspend All Validators checkbox on the top it doesn't necessarily take affect.
private int[] data = new int[3];
This already initializes your array elements to 0. You don't need to repeat that again in the constructor.

What variables do you want to print? If you mean QStrings, those need to be converted to c-Strings. Try:
std::cout << myString.toAscii().data();
def merge_with(f, xs, ys):
xs = a_copy_of(xs) # dict(xs), maybe generalizable?
for (y, v) in ys.iteritems():
xs[y] = v if y not in xs else f(xs[x], v)
merge_with((lambda x, y: x + y), A, B)
You could easily generalize this:
def merge_dicts(f, *dicts):
result = {}
for d in dicts:
for (k, v) in d.iteritems():
result[k] = v if k not in result else f(result[k], v)
Then it can take any number of dicts.
@mikepenz has the right one.
You could just hit SHIFT+COMMAND+A (if you're using OSX and 1.4 android studio) and enter OFFLINE
in the search box.
Then you'll see what mike have shown you.
Just deselect offline

You need to instantiate an object in order to call its member functions. The member functions need an object to operate on; they can't just be used on their own. The main()
function could, for example, look like this:
int main()
{
Name_pairs np;
cout << "Enter names and ages. Use 0 to cancel.\n";
while(np.test())
{
np.read_names();
np.read_ages();
}
np.print();
keep_window_open();
}
The "uni" in unistd stands for "UNIX" - you won't find it on a Windows system.
Most widely used, portable libraries should offer alternative builds or detect the platform and only try to use headers/functions that will be provided, so it's worth checking documentation to see if you've missed some build step - e.g. perhaps running "make" instead of loading a ".sln" Visual C++ solution file.
If you need to fix it yourself, remove the include and see which functions are actually needed, then try to find a Windows equivalent.
If you'd prefer to use autolayout, and want a permanent fixed image in the navigation bar, that doesn't animate in with each screen, this solution works well:
class CustomTitleNavigationController: UINavigationController {
override func viewDidLoad() {
super.viewDidLoad()
let logo = UIImage(named: "MyHeaderImage")
let imageView = UIImageView(image:logo)
imageView.contentMode = .scaleAspectFit
imageView.translatesAutoresizingMaskIntoConstraints = false
navigationBar.addSubview(imageView)
navigationBar.addConstraint (navigationBar.leftAnchor.constraint(equalTo: imageView.leftAnchor, constant: 0))
navigationBar.addConstraint (navigationBar.rightAnchor.constraint(equalTo: imageView.rightAnchor, constant: 0))
navigationBar.addConstraint (navigationBar.topAnchor.constraint(equalTo: imageView.topAnchor, constant: 0))
navigationBar.addConstraint (navigationBar.bottomAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 0))
}
If you change your function definition to use a variable instead:
var get_page = func(url string) string {
...
}
You can override it in your tests:
func TestDownloader(t *testing.T) {
get_page = func(url string) string {
if url != "expected" {
t.Fatal("good message")
}
return "something"
}
downloader()
}
Careful though, your other tests might fail if they test the functionality of the function you override!
The Go authors use this pattern in the Go standard library to insert test hooks into code to make things easier to test:
Old thread, but maybe my answer will help someone. I resolved by executing the query first, then setting an errors variable, then checking if that errors variable array is empty. see simplified example:
$field1 = 'foo';
$field2 = 'bar';
$insert_QUERY = $db->prepare("INSERT INTO table bogus(field1, field2) VALUES (:field1, :field2)");
$insert_QUERY->bindParam(':field1', $field1);
$insert_QUERY->bindParam(':field2', $field2);
$insert_QUERY->execute();
$databaseErrors = $insert_QUERY->errorInfo();
if( !empty($databaseErrors) ){
$errorInfo = print_r($databaseErrors, true); # true flag returns val rather than print
$errorLogMsg = "error info: $errorInfo"; # do what you wish with this var, write to log file etc...
/*
$errorLogMsg will return something like:
error info:
Array(
[0] => 42000
[1] => 1064
[2] => You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'table bogus(field1, field2) VALUES ('bar', NULL)' at line 1
)

For showing result of batch file in text file, you can use
this command
chdir > test.txt
This command will redirect result to test.txt.
When you open test.txt you will found current path of directory in test.txt
WScript.exe
exists in two versions, one in C:\Windows\System32\
and the other in C:\Windows\SysWOW64\
directories. They run respectively in 64 bits and 32 bits (against immediate logic but true).
You may add the following code at the beginning of your script so that it automatically starts again in 32 bits if it detects that it's called in 64 bits.
Note that it transmits the arguments if it calls itself to switch to 64 bits.
' C:\Windows\System32\WScript.exe = WScript.exe
Dim ScriptHost : ScriptHost = Mid(WScript.FullName, InStrRev(WScript.FullName, "\") + 1, Len(WScript.FullName))
Dim oWs : Set oWs = CreateObject("WScript.Shell")
Dim oProcEnv : Set oProcEnv = oWs.Environment("Process")
' Am I running 64-bit version of WScript.exe/Cscript.exe? So, call script again in x86 script host and then exit.
If InStr(LCase(WScript.FullName), LCase(oProcEnv("windir") & "\System32\")) And oProcEnv("PROCESSOR_ARCHITECTURE") = "AMD64" Then
' rebuild arguments
If Not WScript.Arguments.Count = 0 Then
Dim sArg, Arg
sArg = ""
For Each Arg In Wscript.Arguments
sArg = sArg & " " & """" & Arg & """"
Next
End If
Dim sCmd : sCmd = """" & oProcEnv("windir") & "\SysWOW64\" & ScriptHost & """" & " """ & WScript.ScriptFullName & """" & sArg

Palindrome example:
static boolean isPalindrome(String sentence) {
/*If the length of the string is 0 or 1(no more string to check),
*return true, as the base case. Then compare to see if the first
*and last letters are equal, by cutting off the first and last
*letters each time the function is recursively called.*/
int length = sentence.length();
if (length >= 1)
return true;
else {
char first = Character.toLowerCase(sentence.charAt(0));
char last = Character.toLowerCase(sentence.charAt(length-1));
if (Character.isLetter(first) && Character.isLetter(last)) {
if (first == last) {
String shorter = sentence.substring(1, length-1);
return isPalindrome(shorter);
} else {
return false;
}
} else if (!Character.isLetter(last)) {
String shorter = sentence.substring(0, length-1);
return isPalindrome(shorter);
} else {
String shorter = sentence.substring(1);
return isPalindrome(shorter);
}
}
}
Called by:
System.out.println(r.isPalindrome("Madam, I'm Adam"));
Will print true if palindrome, will print false if not.
If the length of the string is 0 or 1(no more string to check), return true, as the base case. This base case will be referred to by function call right before this. Then compare to see if the first and last letters are equal, by cutting off the first and last letters each time the function is recursively called.
First of all we open the file and as datafile
then we apply .read()
method reads the file contents and then we split the data which returns something like: ['5', '10', '6', '6', '20', '1', '7', '30', '4', '8', '40', '3', '9', '23', '1', '4', '13', '6']
and the we applied list slicing on this list to start from the element at index position 1 and skip next 3 elements untill it hits the end of the loop.
with open("sample.txt", "r") as datafile:
print datafile.read().split()[1::3]
Output:
['10', '20', '30', '40', '23', '13']
In my case, I had to run journalctl -xe, and it showed that my disk was full. I then deleted some .gz items from /var/log and I could again restart the postgresql.
I am late here but I resolved same kind of problem in this way that is simple and easy.
<select ng-model="blisterPackTemplateSelected" ng-change="selectedBlisterPack(blisterPackTemplateSelected)">
<option value="">Select Account</option>
<option ng-repeat="blisterPacks in blisterPackTemplates" value="{{blisterPacks.id}}">{{blisterPacks.name}}</option>
and the function for ng-change is as follows;
$scope.selectedBlisterPack= function (value) {
console.log($scope.blisterPackTemplateSelected);
};
Valid longitudes are from -180 to 180 degrees.
Latitudes are supposed to be from -90 degrees to 90 degrees, but areas very near to the poles are not indexable.
So exact limits, as specified by EPSG:900913 / EPSG:3785 / OSGEO:41001 are the following:
Pylint message control is documented in the Pylint manual:
Is it possible to locally disable a particular message?
Yes, this feature has been added in Pylint 0.11. This may be done by adding
# pylint: disable=some-message,another-one
at the desired block level or at the end of the desired line of code.
You can use the message code or the symbolic names.
For example,
def test():
# Disable all the no-member violations in this function
# pylint: disable=no-member
...
global VAR # pylint: disable=global-statement
The manual also has further examples.
There is a wiki that documents all Pylint messages and their codes.
Agree with all above answers of using MutableList but you can also add/remove from List and get a new list as below.
val newListWithElement = existingList + listOf(element)
val newListMinusElement = existingList - listOf(element)
Or
val newListWithElement = existingList.plus(element)
val newListMinusElement = existingList.minus(element)
Since we have a virtual address space of 2^32 and each page size is 2^12, we can store (2^32/2^12) = 2^20 pages. Since each entry into this page table has an address of size 4 bytes, then we have 2^20*4 = 4MB. So the page table takes up 4MB in memory.
You can get the pid of processes by name using pidof
through subprocess.check_output:
from subprocess import check_output
def get_pid(name):
return check_output(["pidof",name])
In [5]: get_pid("java")
Out[5]: '23366\n'
check_output(["pidof",name])
will run the command as "pidof process_name"
, If the return code was non-zero it raises a CalledProcessError.
To handle multiple entries and cast to ints:
from subprocess import check_output
def get_pid(name):
return map(int,check_output(["pidof",name]).split())
In [21]: get_pid("chrome")
Out[21]:
[27698, 27678, 27665, 27649, 27540, 27530, 27517, 14884, 14719, 13849, 13708, 7713, 7310, 7291, 7217, 7208, 7204, 7189, 7180, 7175, 7166, 7151, 7138, 7127, 7117, 7114, 7107, 7095, 7091, 7087, 7083, 7073, 7065, 7056, 7048, 7028, 7011, 6997]
Or pas the -s
flag to get a single pid:
def get_pid(name):
return int(check_output(["pidof","-s",name]))
In [25]: get_pid("chrome")
Out[25]: 27698
You can set a custom toolbar item color dynamically by creating a custom toolbar class:
package view;
import android.app.Activity;
import android.content.Context;
import android.graphics.ColorFilter;
import android.graphics.PorterDuff;
import android.graphics.PorterDuffColorFilter;
import android.support.v7.internal.view.menu.ActionMenuItemView;
import android.support.v7.widget.ActionMenuView;
import android.support.v7.widget.Toolbar;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AutoCompleteTextView;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.TextView;
public class CustomToolbar extends Toolbar{
public CustomToolbar(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
// TODO Auto-generated constructor stub
}
public CustomToolbar(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public CustomToolbar(Context context) {
super(context);
// TODO Auto-generated constructor stub
ctxt = context;
}
int itemColor;
Context ctxt;
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
Log.d("LL", "onLayout");
super.onLayout(changed, l, t, r, b);
colorizeToolbar(this, itemColor, (Activity) ctxt);
}
public void setItemColor(int color){
itemColor = color;
colorizeToolbar(this, itemColor, (Activity) ctxt);
}
/**
* Use this method to colorize toolbar icons to the desired target color

*/
public static void colorizeToolbar(Toolbar toolbarView, int toolbarIconsColor, Activity activity) {
final PorterDuffColorFilter colorFilter
= new PorterDuffColorFilter(toolbarIconsColor, PorterDuff.Mode.SRC_IN);
for(int i = 0; i < toolbarView.getChildCount(); i++) {
final View v = toolbarView.getChildAt(i);
doColorizing(v, colorFilter, toolbarIconsColor);
}
//Step 3: Changing the color of title and subtitle.
toolbarView.setTitleTextColor(toolbarIconsColor);
toolbarView.setSubtitleTextColor(toolbarIconsColor);
}
public static void doColorizing(View v, final ColorFilter colorFilter, int toolbarIconsColor){
if(v instanceof ImageButton) {
((ImageButton)v).getDrawable().setAlpha(255);
((ImageButton)v).getDrawable().setColorFilter(colorFilter);
}
if(v instanceof ImageView) {
((ImageView)v).getDrawable().setAlpha(255);
((ImageView)v).getDrawable().setColorFilter(colorFilter);
}
if(v instanceof AutoCompleteTextView) {
((AutoCompleteTextView)v).setTextColor(toolbarIconsColor);
}
if(v instanceof TextView) {
((TextView)v).setTextColor(toolbarIconsColor);
}
if(v instanceof EditText) {
((EditText)v).setTextColor(toolbarIconsColor);
}
if (v instanceof ViewGroup){
for (int lli =0; lli< ((ViewGroup)v).getChildCount(); lli ++){
doColorizing(((ViewGroup)v).getChildAt(lli), colorFilter, toolbarIconsColor);
}
}
if(v instanceof ActionMenuView) {
for(int j = 0; j < ((ActionMenuView)v).getChildCount(); j++) {
//Step 2: Changing the color of any ActionMenuViews - icons that
//are not back button, nor text, nor overflow menu icon.
final View innerView = ((ActionMenuView)v).getChildAt(j);
if(innerView instanceof ActionMenuItemView) {
int drawablesCount = ((ActionMenuItemView)innerView).getCompoundDrawables().length;
for(int k = 0; k < drawablesCount; k++) {
if(((ActionMenuItemView)innerView).getCompoundDrawables()[k] != null) {
final int finalK = k;
//Important to set the color filter in seperate thread,
//by adding it to the message queue
//Won't work otherwise.
//Works fine for my case but needs more testing
((ActionMenuItemView) innerView).getCompoundDrawables()[finalK].setColorFilter(colorFilter);
// innerView.post(new Runnable() {
// @Override
// public void run() {
// ((ActionMenuItemView) innerView).getCompoundDrawables()[finalK].setColorFilter(colorFilter);
// }
// });
}
}
}
}
}
}
}
then refer to it in your layout file. Now you can set a custom color using
toolbar.setItemColor(Color.Red);

and then I edited it, improved upon it, and posted it here: GitHub:AndroidDynamicToolbarItemColor
You would normally do a Response.Flush followed by a Response.Close, but for some reason the iTextSharp library doesn't seem to like this. The data doesn't make it through and Adobe thinks the PDF is corrupt. Leave out the Response.Close function and see if your results are better:
Response.Clear();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-disposition", "attachment; filename=file.pdf"); // open in a new window
Response.OutputStream.Write(outStream.GetBuffer(), 0, outStream.GetBuffer().Length);
Response.Flush();
// For some reason, if we close the Response stream, the PDF doesn't make it through
//Response.Close();
To be totally exhaustive, things are different if you're using a JPA 1.0 or a JPA 2.0 implementation.
With JPA 1.0, you'd have to use EntityManager#getDelegate()
. But keep in mind that the result of this method is implementation specific i.e. non portable from application server using Hibernate to the other. For example with JBoss you would do:
org.hibernate.Session session = (Session) manager.getDelegate();
But with GlassFish, you'd have to do:
org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession();
I agree, that's horrible, and the spec is to blame here (not clear enough).
With JPA 2.0, there is a new (and much better) EntityManager#unwrap(Class<T>)
method that is to be preferred over EntityManager#getDelegate()
for new applications.
So with Hibernate as JPA 2.0 implementation (see 3.15. Native Hibernate API), you would do:
Session session = entityManager.unwrap(Session.class);
You have to play with JSFiddle loading option :
set it to "No wrap - in body
" instead of "onload"

Just to add to the other answers, there are still noteworthy differences here, specifically when dealing with <svg>
elements.
I have used both .childNodes
and .children
and have preferred working with the HTMLCollection
delivered by the .children
getter.
Today however, I ran into issues with IE/Edge failing when using .children
on an <svg>
.
While .children
is supported in IE on basic HTML elements, it isn't supported on document/document fragments, or SVG elements.
For me, I was able to simply grab the needed elements via .childNodes[n]
because I don't have extraneous text nodes to worry about. You may be able to do the same, but as mentioned elsewhere above, don't forget that you may run into unexpected elements.
Hope this is helpful to someone scratching their head trying to figure out why .children
works elsewhere in their js on modern IE and fails on document or SVG elements.
Get requests should not have content-type because they do not have request entity (that is, a body)
Following line in above code is not working
DB_PASSWORD=$(eval echo ${DB_PASSWORD} | base64 --decode)
Correct line is:
DB_PASSWORD=`echo $PASSWORD|base64 -d`
And save the password in other file as PASSWORD.
At least for the GitHub Flavoured Markdown, you can give the illusion by making all the non-header row entries bold with the regular __
or **
formatting:
|Regular | text | in header | turns bold |
|-|-|-|-|
| __So__ | __bold__ | __all__ | __table entries__ |
| __and__ | __it looks__ | __like a__ | __"headerless table"__ |
Don't include header.php. You should not output HTML when you are going to redirect.
Make a new file, eg. "pre.php". Put this in it:
<?php
include('class.user.php');
include('class.Connection.php');
?>
Then in header.php, include that, in stead of including the two other files. In form.php, include pre.php in stead of header.php.
You could do something like this:
$("#txtArea").on("keypress",function(e) {_x000D_
var key = e.keyCode;_x000D_
_x000D_
// If the user has pressed enter_x000D_
if (key == 13) {_x000D_
document.getElementById("txtArea").value =document.getElementById("txtArea").value + "\n";_x000D_
return false;_x000D_
}_x000D_
else {_x000D_
return true;_x000D_
}_x000D_
});
_x000D_
<textarea id="txtArea"></textarea>
_x000D_
You can do this via a couple ways.
One is when you run your application, you can pass it a flag.
java -Dgate.home="http://gate.ac.uk/wiki/code-repository" your_application
Or set it programmatically in code before the piece of code that needs this property set. Java keeps a Properties
object for System
wide configuration.
Properties props = System.getProperties();
props.setProperty("gate.home", "http://gate.ac.uk/wiki/code-repository");
If you just put '/' in the href it will reload the current window.
<a href="/">
Reload the page
</a>

Instead of constantly generating project metadata via import->maven command, you can generate your project metadata once and the place it in your git repository along with the rest of your source code. After than, using import->git command will import a proper maven-enabled project, assuming you have maven tools installed.
Make sure to place into the source control system all files in project dir that start with '.' such as .classpath and .project along with the entire contents of the .settings directory.
The $(document).ready mechanism is meant to fire after the DOM has been loaded successfully but makes no guarantees as to the state of the images referenced by the page.
When in doubt, fall back on the good ol' window.onload event:
window.onload = function()
{
//your code here
};
Now, this is obviously slower than the jQuery approach. However, you can compromise somewhere in between:
$(document).ready
(
function()
{
var img = document.getElementById("myImage");
var intervalId = setInterval(
function()
{
if(img.complete)
{
clearInterval(intervalId);
//now we can start rotating the header
}
},
50);
}
);
To explain a bit:
we grab the DOM element of the image whose image we want completely loaded
we then set an interval to fire every 50 milliseconds.
if, during one of these intervals, the complete attribute of this image is set to true, the interval is cleared and the rotate operation is safe to start.
As Robert pointed out, quotation marks might do the trick for you:
git stash pop stash@"{1}"
I meet this problem when I try to use mingw to compile the xgboost lib in Win10. Finally I found the solution.
Create a file named as .bashrc in your home directory (usually the C:\Users\username). Then add the path to it. Remember to use quotes if your path contains blank, and remember to use /c/ instead of C:/
For example:
PATH=$PATH:"/c/Program Files/mingw-w64/x86_64-7.2.0-posix-seh-rt_v5-rev1/mingw64/bin"
If you haven't already, create a notebook config file by running
jupyter notebook --generate-config
Then, edit the file jupyter_notebook_config.py
found in the .jupyter
folder of your home directory.
You need to change the line # c.NotebookApp.browser = ''
to c.NotebookApp.browser = 'C:/path/to/your/chrome.exe %s'
On windows 10, Chrome should be located C:/Program Files (x86)/Google/Chrome/Application/chrome.exe
but check on your system to be sure.
Busy waiting won't be a severe drawback if it is short. In my case there was the need to give visual feedback to the user by flashing a control (it is a chart control that can be copied to clipboard, which changes its background for some milliseconds). It works fine this way:
using System.Threading;
...
Clipboard.SetImage(bm); // some code
distribution_chart.BackColor = Color.Gray;
Application.DoEvents(); // ensure repaint, may be not needed
Thread.Sleep(50);
distribution_chart.BackColor = Color.OldLace;
....
JoshAdel's solution uses np.newaxis to add a dimension. An alternative is to use reshape() to align the dimensions in preparation for broadcasting.
data = np.array([[1,1,1],[2,2,2],[3,3,3]])
vector = np.array([1,2,3])
data
# array([[1, 1, 1],
# [2, 2, 2],
# [3, 3, 3]])
vector
# array([1, 2, 3])
data.shape
# (3, 3)
vector.shape
# (3,)
data / vector.reshape((3,1))
# array([[1, 1, 1],
# [1, 1, 1],
# [1, 1, 1]])
Performing the reshape() allows the dimensions to line up for broadcasting:
data: 3 x 3
vector: 3
vector reshaped: 3 x 1
Note that data/vector
is ok, but it doesn't get you the answer that you want. It divides each column of array
(instead of each row) by each corresponding element of vector
. It's what you would get if you explicitly reshaped vector
to be 1x3
instead of 3x1
.
data / vector
# array([[1, 0, 0],
# [2, 1, 0],
# [3, 1, 1]])
data / vector.reshape((1,3))
# array([[1, 0, 0],
# [2, 1, 0],
# [3, 1, 1]])
Corrected a few things and added an alternative select - delete as appropriate.

i think the setTimeout function that you write is not being run. if you use jquery, you can make it run correctly by doing this :
function alertMsg() {
//your func
}
$(document).ready(function() {
setTimeout(alertMsg,3000);
// the function you called by setTimeout must not be a string.
});
You can get value of id,name or value in this way. class name my_class
var id_value = $('.my_class').$(this).attr('id'); //get id value
var name_value = $('.my_class').$(this).attr('name'); //get name value
var value = $('.my_class').$(this).attr('value'); //get value any input or tag
It looks like you are executing that command from a DOS session (see this thread), and that means you need to create the .ssh
directory before said command.
Or you can execute it from the bash session (part of the msysgit distribution), and it should work.
Globally, disabling the back button is indeed bad practice. But, in certain situations, the back button functionality doesn't make sense.
Here's one way to prevent unwanted navigation between pages:
Top page (file top.php
):
<?php
session_start();
$_SESSION[pid]++;
echo "top page $_SESSION[pid]";
echo "<BR><a href='secondary.php?pid=$_SESSION[pid]'>secondary page</a>";
?>
Secondary page (file secondary.php
):
<?php
session_start();
if ($_SESSION[pid] != $_GET[pid])
header("location: top.php");
else {
echo "secondary page $_SESSION[pid]";
echo "<BR><a href='top.php'>top</a>";
}
?>
The effect is to allow navigating from the top page forward to the secondary page and back (e.g. Cancel) using your own links. But, after returning to the top page the browser back button is prevented from navigating to the secondary page.
A agree with the methods mentioned by maxnk, however you may want to reconsider trying to automatically force the browser to download the URL. It may work fine for binary files but for other types of files (text, PDF, images, video), the browser may want to render it in the window (or IFRAME) rather than saving to disk.
If you really do need to make an Ajax call to get the final download links, what about using DHTML to dynamically write out the download link (from the ajax response) into the page? That way the user could either click on it to download (if binary) or view in their browser - or select "Save As" on the link to save to disk. It's an extra click, but the user has more control.
You can also click on the Formulas tab in Excel and select Show Formulas, then use the regular "Find" and "Replace" function. This should not affect the rest of your formula.

Using the standard mysql.createPool(), connections are lazily created by the pool. If you configure the pool to allow up to 100 connections, but only ever use 5 simultaneously, only 5 connections will be made. However if you configure it for 500 connections and use all 500 they will remain open for the durations of the process, even if they are idle!
This means if your MySQL Server max_connections is 510 your system will only have 10 mySQL connections available until your MySQL Server closes them (depends on what you have set your wait_timeout to) or your application closes! The only way to free them up is to manually close the connections via the pool instance or close the pool.
mysql-connection-pool-manager module was created to fix this issue and automatically scale the number of connections dependant on the load. Inactive connections are closed and idle connection pools are eventually closed if there has not been any activity.
// Load modules
const PoolManager = require('mysql-connection-pool-manager');
// Options
const options = {
...example settings
}
// Initialising the instance
const mySQL = PoolManager(options);
// Accessing mySQL directly
var connection = mySQL.raw.createConnection({
host : 'localhost',
user : 'me',
password : 'secret',
database : 'my_db'
});
// Initialising connection
connection.connect();
// Performing query
connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
if (error) throw error;
console.log('The solution is: ', results[0].solution);
});
// Ending connection
connection.end();

For the first iteration 'a' will be the first object in the array, hence a.x + b.x will return 1+2 i.e 3. Now in the next iteration the returned 3 is assigned to a, so a is a number now n calling a.x will give NaN.
Simple solution is first mapping the numbers in array and then reducing them as below:
arr.map(a=>a.x).reduce(function(a,b){return a+b})
here arr.map(a=>a.x)
will provide an array of numbers [1,2,4] now using .reduce(function(a,b){return a+b})
will simple add these numbers without any hassel
Another simple solution is just to provide an initial sum as zero by assigning 0 to 'a' as below:
arr.reduce(function(a,b){return a + b.x},0)
If the server doesn't have enough memory also will cause this problem. This is my personal experience with Godaddy VPS.
Try to use this:
android:windowSoftInputMode="stateHidden|adjustPan"
Cloud: the hardware running the application scales to meet the demand (potentially crossing multiple machines, networks, etc).
Grid: the application scales to take as much hardware as possible (for example in the hope of finding extra-terrestrial intelligence).
Cluster: this is an old term referring to one OS instance or one DB instance installed across multiple machines. It was done with special OS handling, proprietary drivers, low latency network cards with fat cables, and various hardware bedfellows.
(We love you SGI, but notice that "Cloud" and "Grid" are available to the little guy and your NUMAlink never has been...)
If you don't want to actually navigate to a new page you can also have your anchor somewhere on the page like this.
<a id="the_anchor" href="">
And then to assign your string of JavaScript to the the onclick of the anchor, put this somewhere else (i.e. the header, later in the body, whatever):
<script>
var js = "alert('I am your string of JavaScript');"; // js is your string of script
document.getElementById('the_anchor').href = 'javascript:' + js;
</script>
If you have all of this info on the server before sending out the page, then you could also simply place the JavaScript directly in the href
attribute of the anchor like so:
<a href="javascript:alert('I am your script.'); alert('So am I.');">Click me</a>
Adding to ben.bourdin answer, you can at least in any HTML based application, check if the browser supports HLS in its video element:
Let´s assume that your video element ID is "myVideo", then through javascript you can use the "canPlayType" function (http://www.w3schools.com/tags/av_met_canplaytype.asp)
var videoElement = document.getElementById("myVideo");
if(videoElement.canPlayType('application/vnd.apple.mpegurl') === "probably" || videoElement.canPlayType('application/vnd.apple.mpegurl') === "maybe"){
//Actions like playing the .m3u8 content
}
else{
//Actions like playing another video type
}
The canPlayType function, returns:
"" when there is no support for the specified audio/video type
"maybe" when the browser might support the specified audio/video type
"probably" when it most likely supports the specified audio/video type (you can use just this value in the validation to be more sure that your browser supports the specified type)
Hope this help :)
Best regards!
This answer seems good.
however, it lead me towards an error as it resulted with
Configuration 'xyz' could not be found in project ...
error in build.
It is requierd not only to updated build configurations, but also serve
ones.
So just to leave no confusions:
--env
is not supported in angular 6
--env
got changed into --configuration

(and is now more powerful)angular.json

The data is stored on the device, in your application's private data area. It is not in an Eclipse project.
If the file is the too big to use as a list, and you simply want to reverse the file, you can initially write the file in reversed order and then read one line at the time from the file's end (and write it to another file) with file-read-backwards module

You should explore SQL Server\Memory Manager performance counters.
When I had this problem I could see only a part of my text and this is the solution for that:
Be sure to set the AutoSize property to true.
output.AutoSize = true;
You can do like this:
rename %CURR_DIR%\ftp\mywish1.txt text.txt
for /f %%a in (%CURR_DIR%\ftp\text.txt) do (
if "%%a" EQU "ex3" (
echo ex5 >> %CURR_DIR%\ftp\mywish1.txt
) else (
echo %%a >> %CURR_DIR%\ftp\mywish1.txt
)
)
del %CURR_DIR%\ftp\text.txt
int i=99;//is what row you want to select and focus
listViewRamos.FocusedItem = listViewRamos.Items[0];
listViewRamos.Items[i].Selected = true;
listViewRamos.Select();
listViewRamos.EnsureVisible(i);//This is the trick
select convert(varchar(11), transfer_date, 106)
got me my desired result of date formatted as 07 Mar 2018
My column transfer_date
is a datetime type column and I am using SQL Server 2017 on azure
Instead of:
input:not(disabled)not:[type="submit"]:focus {}
Use:
input:not([disabled]):not([type="submit"]):focus {}
disabled
is an attribute so it needs the brackets, and you seem to have mixed up/missing colons and parentheses on the :not()
selector.
Demo: http://jsfiddle.net/HSKPx/
One thing to note: I may be wrong, but I don't think disabled
inputs can normally receive focus, so that part may be redundant.
Alternatively, use :enabled
input:enabled:not([type="submit"]):focus { /* styles here */ }
Again, I can't think of a case where disabled input can receive focus, so it seems unnecessary.

You can split the result into two-hex-character chunks if necessary.
With Spring Boot, I'm not entirely sure why this was necessary (I got the /error
fallback even though @ResponseBody
was defined on an @ExceptionHandler
), but the following in itself did not work:
@ResponseBody
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler(IllegalArgumentException.class)
public ErrorMessage handleIllegalArguments(HttpServletRequest httpServletRequest, IllegalArgumentException e) {
log.error("Illegal arguments received.", e);
ErrorMessage errorMessage = new ErrorMessage();
errorMessage.code = 400;
errorMessage.message = e.getMessage();
return errorMessage;
}
It still threw an exception, apparently because no producible media types were defined as a request attribute:
// AbstractMessageConverterMethodProcessor
@SuppressWarnings("unchecked")
protected <T> void writeWithMessageConverters(T value, MethodParameter returnType,
ServletServerHttpRequest inputMessage, ServletServerHttpResponse outputMessage)
throws IOException, HttpMediaTypeNotAcceptableException, HttpMessageNotWritableException {
Class<?> valueType = getReturnValueType(value, returnType);
Type declaredType = getGenericType(returnType);
HttpServletRequest request = inputMessage.getServletRequest();
List<MediaType> requestedMediaTypes = getAcceptableMediaTypes(request);
List<MediaType> producibleMediaTypes = getProducibleMediaTypes(request, valueType, declaredType);
if (value != null && producibleMediaTypes.isEmpty()) {
throw new IllegalArgumentException("No converter found for return value of type: " + valueType); // <-- throws
}
// ....
@SuppressWarnings("unchecked")
protected List<MediaType> getProducibleMediaTypes(HttpServletRequest request, Class<?> valueClass, Type declaredType) {
Set<MediaType> mediaTypes = (Set<MediaType>) request.getAttribute(HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE);
if (!CollectionUtils.isEmpty(mediaTypes)) {
return new ArrayList<MediaType>(mediaTypes);
So I added them.
@ResponseBody
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler(IllegalArgumentException.class)
public ErrorMessage handleIllegalArguments(HttpServletRequest httpServletRequest, IllegalArgumentException e) {
Set<MediaType> mediaTypes = new HashSet<>();
mediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
httpServletRequest.setAttribute(HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE, mediaTypes);
log.error("Illegal arguments received.", e);
ErrorMessage errorMessage = new ErrorMessage();
errorMessage.code = 400;
errorMessage.message = e.getMessage();
return errorMessage;
}
And this got me through to have a "supported compatible media type", but then it still didn't work, because my ErrorMessage
was faulty:
public class ErrorMessage {
int code;
String message;
}
JacksonMapper did not handle it as "convertable", so I had to add getters/setters, and I also added @JsonProperty
annotation
public class ErrorMessage {
@JsonProperty("code")
private int code;
@JsonProperty("message")
private String message;
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
Then I received my message as intended
{"code":400,"message":"An \"url\" parameter must be defined."}
I had used JCL about 2 years back so cannot write a code for you but here is the idea;
again i apologize for solution without code, but i am out of touch by 2 yrs+
you can download USBview and get all the information you need. Along with the list of devices it will also show you the configuration of each device.
Following program describe how bidirectional relation work in hibernate.
When parent will save its list of child object will be auto save.
On Parent side:
@Entity
@Table(name="clients")
public class Clients implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@OneToMany(mappedBy="clients", cascade=CascadeType.ALL)
List<SmsNumbers> smsNumbers;
}
And put the following annotation on the child side:
@Entity
@Table(name="smsnumbers")
public class SmsNumbers implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
int id;
String number;
String status;
Date reg_date;
@ManyToOne
@JoinColumn(name = "client_id")
private Clients clients;
// and getter setter.
}
Main class:
public static void main(String arr[])
{
Session session = HibernateUtil.openSession();
//getting transaction object from session object
session.beginTransaction();
Clients cl=new Clients("Murali", "1010101010");
SmsNumbers sms1=new SmsNumbers("99999", "Active", cl);
SmsNumbers sms2=new SmsNumbers("88888", "InActive", cl);
SmsNumbers sms3=new SmsNumbers("77777", "Active", cl);
List<SmsNumbers> lstSmsNumbers=new ArrayList<SmsNumbers>();
lstSmsNumbers.add(sms1);
lstSmsNumbers.add(sms2);
lstSmsNumbers.add(sms3);
cl.setSmsNumbers(lstSmsNumbers);
session.saveOrUpdate(cl);
session.getTransaction().commit();
session.close();
}
Tracing helped me find what the problem was (Thank you Fabian for that suggestion). I found with further testing that I could get the client certificate to work on another server (Windows Server 2012). I was testing this on my development machine (Window 7) so I could debug this process. So by comparing the trace to an IIS Server that worked and one that did not I was able to pinpoint the relevant lines in the trace log. Here is a portion of a log where the client certificate worked. This is the setup right before the send
System.Net Information: 0 : [17444] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=CredentialsNeeded).
System.Net Information: 0 : [17444] SecureChannel#54718731 - We have user-provided certificates. The server has not specified any issuers, so try all the certificates.
System.Net Information: 0 : [17444] SecureChannel#54718731 - Selected certificate:
Here is what the trace log looked like on the machine where the client certificate failed.
System.Net Information: 0 : [19616] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=CredentialsNeeded).
System.Net Information: 0 : [19616] SecureChannel#54718731 - We have user-provided certificates. The server has specified 137 issuer(s). Looking for certificates that match any of the issuers.
System.Net Information: 0 : [19616] SecureChannel#54718731 - Left with 0 client certificates to choose from.
System.Net Information: 0 : [19616] Using the cached credential handle.
Focusing on the line that indicated the server specified 137 issuers I found this Q&A that seemed similar to my issue. The solution for me was not the one marked as an answer since my certificate was in the trusted root. The answer is the one under it where you update the registry. I just added the value to the registry key.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL
Value name: SendTrustedIssuerList Value type: REG_DWORD Value data: 0 (False)
After adding this value to the registry it started to work on my Windows 7 machine. This appears to be a Windows 7 issue.
From man curl
:
-x, --proxy <[protocol://][user:password@]proxyhost[:port]>
Use the specified HTTP proxy.
If the port number is not specified, it is assumed at port 1080.
General way:
export http_proxy=http://your.proxy.server:port/
Then you can connect through proxy from (many) application.
And, as per comment below, for https:
export https_proxy=https://your.proxy.server:port/
Most of the time you would create a list in groovy rather than an array. You could do it like this:
names = ["lucas", "Fred", "Mary"]
Alternately, if you did not want to quote everything like you did in the ruby example, you could do this:
names = "lucas Fred Mary".split()
I needed to check visibility in elements inside scrollable DIV container
//p = DIV container scrollable
//e = element
function visible_in_container(p, e) {
var z = p.getBoundingClientRect();
var r = e.getBoundingClientRect();
// Check style visiblilty and off-limits
return e.style.opacity > 0 && e.style.display !== 'none' &&
e.style.visibility !== 'hidden' &&
!(r.top > z.bottom || r.bottom < z.top ||
r.left > z.right || r.right < z.left);
}
A bit of a late entry - but hopefully still useful to someone out there:-
Here's a simplified snippet for sending an in-memory string as an email attachment (a CSV file in this particular case).
using (var stream = new MemoryStream())
using (var writer = new StreamWriter(stream)) // using UTF-8 encoding by default
using (var mailClient = new SmtpClient("localhost", 25))
using (var message = new MailMessage("[email protected]", "[email protected]", "Just testing", "See attachment..."))
{
writer.WriteLine("Comma,Seperated,Values,...");
writer.Flush();
stream.Position = 0; // read from the start of what was written
message.Attachments.Add(new Attachment(stream, "filename.csv", "text/csv"));
mailClient.Send(message);
}
The StreamWriter and underlying stream should not be disposed until after the message has been sent (to avoid ObjectDisposedException: Cannot access a closed Stream
).
If you want to use any external library here is Apache commons math library using you can calculate the Median.
For more methods and use take look at the API documentation
import org.apache.commons.math3.*;
.....
......
........
//calculate median
public double getMedian(double[] values){
Median median = new Median();
double medianValue = median.evaluate(values);
return medianValue;
}
.......
Update
Calculate in program
Generally, median is calculated using the following two formulas given here
If n is odd then Median (M) = value of ((n + 1)/2)th item term.
If n is even then Median (M) = value of [((n)/2)th item term + ((n)/2 + 1)th item term ]/2
In your program you have numArray
, first you need to sort array using Arrays#sort
Arrays.sort(numArray);
int middle = numArray.length/2;
int medianValue = 0; //declare variable
if (numArray.length%2 == 1)
medianValue = numArray[middle];
else
medianValue = (numArray[middle-1] + numArray[middle]) / 2;
How would I 'attach' a console/terminal-view to an applications output so I can see what it may be saying?
About this question, I know it is possible to catch the output, even when you didn't launch sceen command before launching the processus.
While I never tried it, I've found an interesting article which explains how to do using GDB (and without restarting your process).
redirecting-output-from-a-running-process
Basically:
By the way, if you are running a linux OS on i386 box, comments are talking about a better tool to redirect output to a new console : 'retty' . If so, consider its use.
I have a working example with an img-tag, but your images won't display. The difference I see is the content-type.
I checked the github image from your post (the google doc images don't load at all because of connection failures). The image from github is delivered as content-type: text/plain, which won't get rendered as an image by your browser.
The correct content-type value for svg is image/svg+xml. So you have to make sure that svg files set the correct mime type, but that's a server issue.
Try it with http://svg.tutorial.aptico.de/grafik_svg/dummy3.svg and don't forget to specify width and height in the tag.
<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>
That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em'
as the measurement, you may want to use other units, like 'px'
.
EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:
In your HTML page, containing the <p>
tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:
<head>
<style type="text/css">
p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>
So above, all <p>
elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:
<head>
<style type="text/css">
.container p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<div class="container">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</div>
<p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>
In the example above, only the <p>
element inside the div, whose class name is 'container', will have the styles applied - and not the <p>
element outside the container.
In addition to the above, you can collect your styles together and remove the style element from the <head>
tag, replacing it with a <link>
tag, which points to an external CSS file. This external file is where you'd now put your <p>
tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.
Autobahn has a good websocket client implementation for Python as well as some good examples. I tested the following with a Tornado WebSocket server and it worked.
from twisted.internet import reactor
from autobahn.websocket import WebSocketClientFactory, WebSocketClientProtocol, connectWS
class EchoClientProtocol(WebSocketClientProtocol):
def sendHello(self):
self.sendMessage("Hello, world!")
def onOpen(self):
self.sendHello()
def onMessage(self, msg, binary):
print "Got echo: " + msg
reactor.callLater(1, self.sendHello)
if __name__ == '__main__':
factory = WebSocketClientFactory("ws://localhost:9000")
factory.protocol = EchoClientProtocol
connectWS(factory)
reactor.run()
You can also try this filter
sharpen_filter = np.array([[0, -1, 0], [-1, 5, -1], [0, -1, 0]])
sharped_img = cv2.filter2D(image, -1, sharpen_filter)
<input type="text" [ngModel]="mymodel" (keypress)="mymodel=$event.target.value"/>
{{mymodel}}
You can through option
Try this with some modifications
<div trbidi="on">
<script type="text/javascript">
function MostrarVideo(idYouTube)
{
var contenedor = document.getElementById('divInnerVideo');
if(idYouTube == '')
{contenedor.innerHTML = '';
} else{
var url = idYouTube;
contenedor.innerHTML = '<iframe width="560" height="315" src="https://www.youtube.com/embed/'+ url +'" frameborder="0" allowfullscreen></iframe>';
}
}
</script>
<select onchange="MostrarVideo(this.value);">
<option selected disabled>please selected </option>
<option value="qycqF1CWcXg">test1</option>
<option value="hniPHaBgvWk">test2</option>
<option value="bOQA33VNo7w">test3</option>
</select>
<div id="divInnerVideo">
</div>
If you want to put a default page placed inside id="divInnerVideo"
example:
<div id="divInnerVideo">
<iframe width="560" height="315" src="https://www.youtube-nocookie.com/embed/pES8SezkV8w?rel=0&showinfo=0" frameborder="0" allowfullscreen></iframe>

If you are running on headless CI and are installing the Android SDK through command line, make sure to include the m2repository packages in the --filter
argument:
android update sdk --no-ui --filter platform-tools,build-tools-19.0.1,android-19,extra-android-support,extra-android-m2repository,extra-google-m2repository
Update
As of Android SDK Manager rev. 22.6.4 this does not work anymore. Try this instead:
android list sdk --all
You will get a list of all available SDK packages. Look up the numerical values of the components from the first command above ("Google Repository" and others you might be missing).
Install the packages using their numerical values:
android update sdk --no-ui --all --filter <num>
Update #2 (Sept 2017)
With the "new" Android SDK tools that were released earlier this year, the android
command is now deprecated, and similar functionality has been moved to a new tool called sdkmanager
:
List installed components:
sdkmanager --list
Update installed components:
sdkmanager --update
Install a new component (e.g. build tools version 26.0.0
):
sdkmanager 'build-tools;26.0.0'
For dynamic 2D charts, I have been using JChart2D. It's fast, simple, and being updated regularly. The author has been quick to respond to my one bug report and few feature requests. We, at our company, prefer it over JFreeChart because it was designed for dynamic use, unlike JFreeChart.
This means that somewhere else in your code, you have something like:
sum = 0
Which shadows the builtin sum (which is callable) with an int (which isn't).
ListView myListView = (ListView) rootView.findViewById(R.id.myListView);
ArrayList<String> myStringArray1 = new ArrayList<String>();
myStringArray1.add("something");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);
Try it like this
public OnClickListener moreListener = new OnClickListener() {
@Override
public void onClick(View v) {
adapter = null;
myStringArray1.add("Andrea");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
};
The way you are doing it is indeed the recommended one (for Python 2.x).
The issue of whether the class is passed explicitly to super
is a matter of style rather than functionality. Passing the class to super
fits in with Python's philosophy of "explicit is better than implicit".
It appears that SQL Server 2008 R2 can be downloaded with or without the management tools. I honestly have NO IDEA why someone would not want the management tools. But either way, the options are here:
http://www.microsoft.com/sqlserver/en/us/editions/express.aspx
and the one for 64 bit WITH the management tools (management studio) is here:
http://www.microsoft.com/sqlserver/en/us/editions/express.aspx
From the first link I presented, the 3rd and 4th include the management studio for 32 and 64 bit respectively.
You can try using FormulaLocal property instead of Formula. Then the semicolon should work.
Pandas merge

x, y, z = [1, 2, 3], [4, 5], [6, 7]
# get dfs with same, constant index
x = pd.DataFrame({'x': x}, index=np.repeat(0, len(x))
y = pd.DataFrame({'y': y}, index=np.repeat(0, len(y))
z = pd.DataFrame({'z': z}, index=np.repeat(0, len(z))
# get all permutations stored in a new df
df = pd.merge(x, pd.merge(y, z, left_index=True, righ_index=True),
left_index=True, right_index=True)
<corners android:bottomRightRadius="180dip"
android:bottomLeftRadius="180dip"
android:topRightRadius="180dip"
android:topLeftRadius="180dip"/>
<solid android:color="#6E6E6E"/> <!-- this one is ths color of the Rounded Button -->
and add this to the button code
android:layout_width="50dp"
android:layout_height="50dp"
You do not need any client side code if doing this is ASP.NET. The example below is a boostrap input box with a search button with an fontawesome icon.
You will see that in place of using a regular < div > tag with a class of "input-group" I have used a asp:Panel. The DefaultButton property set to the id of my button, does the trick.
In example below, after typing something in the input textbox, you just hit enter and that will result in a submit.
<asp:Panel DefaultButton="btnblogsearch" runat="server" CssClass="input-group blogsearch">
<asp:TextBox ID="txtSearchWords" CssClass="form-control" runat="server" Width="100%" Placeholder="Search for..."></asp:TextBox>
<span class="input-group-btn">
<asp:LinkButton ID="btnblogsearch" runat="server" CssClass="btn btn-default"><i class="fa fa-search"></i></asp:LinkButton>
</span></asp:Panel>
Set style= "display:none;"
. By setting visible=false
, it will not render button in the browser. Thus,client side script wont execute.
<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />
html markup should be
<button id="btnsave" onclick="fncsave()">Save</button>
Change javascript to
<script type="text/javascript">
function fncsave()
{
document.getElementById('<%= savebtn.ClientID %>').click();
}
</script>
Same thing you can implement in Python-
import requests,json
def get_media_id(media_url):
url = 'https://api.instagram.com/oembed/?callback=&url=' + media_url
response = requests.get(url).json()
print(response['media_id'])
get_media_id('MEDIA_URL')
Not possible but if you try CTE, this would be the code:
ALTER VIEW [dbo].[VW_PuntosDeControlDeExpediente]
AS
WITH TEMP (RefLocal, IdPuntoControl, Descripcion)
AS
(
SELECT
EX.RefLocal
, PV.IdPuntoControl
, PV.Descripcion
FROM [dbo].[PuntosDeControl] AS PV
INNER JOIN [dbo].[Vertidos] AS VR ON VR.IdVertido = PV.IdVertido
INNER JOIN [dbo].[ExpedientesMF] AS MF ON MF.IdExpedienteMF = VR.IdExpedienteMF
INNER JOIN [dbo].[Expedientes] AS EX ON EX.IdExpediente = MF.IdExpediente
)
SELECT
Q1.[RefLocal]
, [IdPuntoControl] = ( SELECT MAX(IdPuntoControl) FROM TEMP WHERE [RefLocal] = Q1.[RefLocal] AND [Descripcion] = Q1.[Descripcion] )
, Q1.[Descripcion]
FROM TEMP AS Q1
GROUP BY Q1.[RefLocal], Q1.[Descripcion]
GO
Relative paths are relative to current working directory. If you do not your want your path to be, it must be absolute.
But there is an often used trick to build an absolute path from current script: use its __file__
special attribute:
from pathlib import Path
path = Path(__file__).parent / "../data/test.csv"
with path.open() as f:
test = list(csv.reader(f))
This requires python 3.4+ (for the pathlib module).
If you still need to support older versions, you can get the same result with:
import csv
import os.path
my_path = os.path.abspath(os.path.dirname(__file__))
path = os.path.join(my_path, "../data/test.csv")
with open(path) as f:
test = list(csv.reader(f))
[2020 edit: python3.4+ should now be the norm, so I moved the pathlib version inspired by jpyams' comment first]
To insert tab space
between two words/sentences I usually use
 
and  
You can use justify-content: space-between
in .test
like so:
.test {_x000D_
display: flex;_x000D_
justify-content: space-between;_x000D_
width: 20rem;_x000D_
border: .1rem red solid;_x000D_
}
_x000D_
<div class="test">_x000D_
<button>test</button>_x000D_
<button>test</button>_x000D_
</div>
_x000D_
For those who want to use Bootstrap 4 can use justify-content-between
:
div {_x000D_
width: 20rem;_x000D_
border: .1rem red solid;_x000D_
}
_x000D_
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet" />_x000D_
<div class="d-flex justify-content-between">_x000D_
<button>test</button>_x000D_
<button>test</button>_x000D_
</div>
_x000D_
You need to add a name
attribute to your dropdown list, then you need to add a required
attribute, and then you can reference the error using myForm.[input name].$error.required
:
HTML:
<form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
<input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
<select name="service_id" class="Sitedropdown" style="width: 220px;"
ng-model="ServiceID"
ng-options="service.ServiceID as service.ServiceName for service in services"
required>
<option value="">Select Service</option>
</select>
<span ng-show="myForm.service_id.$error.required">Select service</span>
</form>
Controller:
function Ctrl($scope) {
$scope.services = [
{ServiceID: 1, ServiceName: 'Service1'},
{ServiceID: 2, ServiceName: 'Service2'},
{ServiceID: 3, ServiceName: 'Service3'}
];
$scope.save = function(myForm) {
console.log('Selected Value: '+ myForm.service_id.$modelValue);
alert('Data Saved! without validate');
};
}
Here's a working plunker.
My solution was to remove the Eclipse ADT plugin via menu "Help > About Eclipse SDK > Installation Details". Eclipse will restart.
Next go to Menu "Help > Install New Software", then add the ADT plugin url "https://dl-ssl.google.com/android/eclipse" (or select the existing link from the dropdown).
This will re-install the latest ADT, including the DDMS files.
I think you dont need SelectedText
but you may need
String status = "The status of my combobox is " + comboBoxTest.Text;
Well that is Because of
you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception. and the one way is to encrypt that data Directly into the String.
look this. Try and u will be able to resolve this
public static String decrypt(String encryptedData) throws Exception {
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.DECRYPT_MODE, key);
String decordedValue = new BASE64Decoder().decodeBuffer(encryptedData).toString().trim();
System.out.println("This is Data to be Decrypted" + decordedValue);
return decordedValue;
}
hope that will help.
I realize this question is old, but it recently popped up in a search I just ran, so I thought I'd post an alternative to the above answer.
If you are looking to generate create
scripts programmatically in .Net, I would highly recommend looking into Server Management Objects (SMO) or Distributed Management Objects (DMO) -- depending on which version of SQL Server you are using (the former is 2005+, the latter 2000). Using these libraries, scripting a table is as easy as:
Server server = new Server(".");
Database northwind = server.Databases["Northwind"];
Table categories = northwind.Tables["Categories"];
StringCollection script = categories.Script();
string[] scriptArray = new string[script.Count];
script.CopyTo(scriptArray, 0);
Here is a blog post with more information.
Just to add an additional function should you need it. You can include a variable in the named location, for example a date identifier
date <- yyyymmdd
save(city, file=paste0("c:\\myuser\\somelocation\\",date,"_RData.Data")
This was you can always keep a check of when it was run
Use the Android logging utility.
http://developer.android.com/reference/android/util/Log.html
Log has a bunch of static methods for accessing the different log levels. The common thread is that they always accept at least a tag and a log message.
Tags are a way of filtering output in your log messages. You can use them to wade through the thousands of log messages you'll see and find the ones you're specifically looking for.
You use the Log functions in Android by accessing the Log.x objects (where the x method is the log level). For example:
Log.d("MyTagGoesHere", "This is my log message at the debug level here");
Log.e("MyTagGoesHere", "This is my log message at the error level here");
I usually make it a point to make the tag my class name so I know where the log message was generated too. Saves a lot of time later on in the game.
You can see your log messages using the logcat tool for android:
adb logcat
Or by opening the eclipse Logcat view by going to the menu bar
Window->Show View->Other then select the Android menu and the LogCat view
From the menu:
Build|Generate Signed APK
or
Build|Build APK
(the latter if you don't need a signed one to publish to the Play Store)
In the current version of Google Play store Console as of(August 2017) here is the procedure of unpublishing your app.
After clicking unpublish a dialog will popup confirm and save the changes.
I suppose one thing that may be concerning you is whether or not the entries could change, so that the 2 becomes a different number, for instance. You can put your mind at ease here, because in Python, integers are immutable, meaning they cannot change after they are created.
Not everything in Python is immutable, though. For example, lists are mutable---they can change after being created. So for example, if you had a list of lists
>>> a = [[1], [2], [3]]
>>> a[0].append(7)
>>> a
[[1, 7], [2], [3]]
Here, I changed the first entry of a
(I added 7
to it). One could imagine shuffling things around, and getting unexpected things here if you are not careful (and indeed, this does happen to everyone when they start programming in Python in some way or another; just search this site for "modifying a list while looping through it" to see dozens of examples).
It's also worth pointing out that x = x + [a]
and x.append(a)
are not the same thing. The second one mutates x
, and the first one creates a new list and assigns it to x
. To see the difference, try setting y = x
before adding anything to x
and trying each one, and look at the difference the two make to y
.
Place the following in your jQuery mouseover
event handler:
$(this).css('color', 'red');
To set both color and size at the same time:
$(this).css({ 'color': 'red', 'font-size': '150%' });
You can set any CSS attribute using the .css()
jQuery function.
Application Programming Interface is a set of routines/data structures/classes which specifies a way to interact with the target platform/software like OS X, Android, project management application, virtualization software etc.
While Software Development Kit is a wrapper around API/s that makes the job easy for developers.
For example, Android SDK facilitates developers to interact with the Android platform as a whole while the platform itself is built by composite software components communicating via APIs.
Also, sometimes SDKs are built to facilitate development in a specific programming language. For example, Selenium web driver (built in Java) provides APIs to drive any browser natively, while capybara can be considered an an SDK that facilitates Ruby developers to use Selenium web driver. However, Selenium web driver is also an SDK by itself as it combines interaction with various native browser drivers into one package.

IMO, above calls does not looks RESTful, however these are quick and efficient workaround (y). But length of the URL is limited by webserver, eg tomcat.
RESTful attempt:
POST http://example.com/api/batchtask
[
{
method : "GET",
headers : [..],
url : "/users/id1"
},
{
method : "GET",
headers : [..],
url : "/users/id2"
}
]
Server will reply URI of newly created batchtask resource.
201 Created
Location: "http://example.com/api/batchtask/1254"
Now client can fetch batch response or task progress by polling
GET http://example.com/api/batchtask/1254
This is how others attempted to solve this issue:
Instead of an annoying confirmation popup, it would be nice to delay leaving just a bit (matter of milliseconds) to manage successfully posting the unsaved data to the server, which I managed for my site using writing dummy text to the console like this:
window.onbeforeunload=function(e){
// only take action (iterate) if my SCHEDULED_REQUEST object contains data
for (var key in SCHEDULED_REQUEST){
postRequest(SCHEDULED_REQUEST); // post and empty SCHEDULED_REQUEST object
for (var i=0;i<1000;i++){
// do something unnoticable but time consuming like writing a lot to console
console.log('buying some time to finish saving data');
};
break;
};
}; // no return string --> user will leave as normal but data is send to server
Edit: See also Synchronous_AJAX and how to do that with jquery
Besides the usages that JAiro mentioned, I like this one:
def getConnectionProps = {
( Config.getHost, Config.getPort, Config.getSommElse, Config.getSommElsePartTwo )
}
If someone needs all connection properties, he can do:
val ( host, port, sommEsle, someElsePartTwo ) = getConnectionProps
If you need just a host and a port, you can do:
val ( host, port, _, _ ) = getConnectionProps
Use the following excellent npm package: to-arraybuffer
.
Or, you can implement it yourself. If your buffer is called buf
, do this:
buf.buffer.slice(buf.byteOffset, buf.byteOffset + buf.byteLength)
override func draw(_ rect: CGRect)
{
AlertView.layer.cornerRadius = 4
AlertView.clipsToBounds = true
btnOk.layer.cornerRadius = 4
btnOk.clipsToBounds = true
}
class func instanceFromNib() -> LAAlertView {
return UINib(nibName: "LAAlertView", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! LAAlertView
}
@IBAction func okBtnDidClicked(_ sender: Any) {
removeAlertViewFromWindow()
UIView.animate(withDuration: 0.4, delay: 0.0, options: .allowAnimatedContent, animations: {() -> Void in
self.AlertView.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
}, completion: {(finished: Bool) -> Void in
self.AlertView.transform = CGAffineTransform.identity
self.AlertView.transform = CGAffineTransform(scaleX: 0.0, y: 0.0)
self.AlertView.isHidden = true
self.AlertView.alpha = 0.0
self.alpha = 0.5
})
}
func removeAlertViewFromWindow()
{
for subview in (appDel.window?.subviews)! {
if subview.tag == 500500{
subview.removeFromSuperview()
}
}
}
public func openAlertView(title:String , string : String ){
lblTital.text = title
txtView.text = string
self.frame = CGRect(x: 0, y: 0, width: screenWidth, height: screenHeight)
appDel.window!.addSubview(self)
AlertView.alpha = 1.0
AlertView.isHidden = false
UIView.animate(withDuration: 0.2, animations: {() -> Void in
self.alpha = 1.0
})
AlertView.transform = CGAffineTransform(scaleX: 0.0, y: 0.0)
UIView.animate(withDuration: 0.3, delay: 0.2, options: .allowAnimatedContent, animations: {() -> Void in
self.AlertView.transform = CGAffineTransform(scaleX: 1.1, y: 1.1)
}, completion: {(finished: Bool) -> Void in
UIView.animate(withDuration: 0.2, animations: {() -> Void in
self.AlertView.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
})
})
}
If you want to restash a lost stash, you need to find the hash of your lost stash first.
As Aristotle Pagaltzis suggested a git fsck
should help you.
Personally I use my log-all
alias which show me every commit (recoverable commits) to have a better view of the situation :
git log --graph --decorate --pretty=oneline --abbrev-commit --all $(git fsck --no-reflogs | grep commit | cut -d' ' -f3)
You can do an even faster search if you're looking only for "WIP on" messages.
Once you know your sha1, you simply change your stash reflog to add the old stash :
git update-ref refs/stash ed6721d
You'll probably prefer to have an associated message so a -m
git update-ref -m "$(git log -1 --pretty=format:'%s' ed6721d)" refs/stash ed6721d
And you'll even want to use this as an alias :
restash = !git update-ref -m $(git log -1 --pretty=format:'%s' $1) refs/stash $1
Yes, just delete the branch by running git push origin :branchname
. To fix a new issue later, branch off from master again.
This problem happens when you not allow unsecure connections via localhost, or maybe you tried to accept unsecure connections via http.
To fix this, add this on info.plist
:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSAllowsArbitraryLoadsInWebContent</key>
<true/>
<key>NSAllowsLocalNetworking</key>
<true/>
</dict>
It could also use the forfiles command:
forfiles /s
and also check if it is a directory
forfiles /p c:\ /s /m *.* /c "cmd /c if @isdir==true echo @file is a directory"
Considering the popularity of this question and the interest behind such a function I am surprised to see that there is no answer involving T4 yet.
In this sample code I will demonstrate a very simple example of how you can use the powerful templating engine to do what the compiler pretty much does behind the scenes with generics.
Instead of going through hoops and sacrificing compile-time certainty you can simply generate the function you want for every type you like and use that accordingly (at compile time!).
In order to do this:
<#@ template language="C#" #>
<#@ output extension=".cs" #>
<#@ assembly name="System.Core" #>
<# Type[] types = new[] {
typeof(Int16), typeof(Int32), typeof(Int64),
typeof(UInt16), typeof(UInt32), typeof(UInt64)
};
#>
using System;
public static class MaxMath {
<# foreach (var type in types) {
#>
public static <#= type.Name #> Max (<#= type.Name #> val1, <#= type.Name #> val2) {
return val1 > val2 ? val1 : val2;
}
<#
} #>
}
That's it. You're done now.
Saving this file will automatically compile it to this source file:
using System;
public static class MaxMath {
public static Int16 Max (Int16 val1, Int16 val2) {
return val1 > val2 ? val1 : val2;
}
public static Int32 Max (Int32 val1, Int32 val2) {
return val1 > val2 ? val1 : val2;
}
public static Int64 Max (Int64 val1, Int64 val2) {
return val1 > val2 ? val1 : val2;
}
public static UInt16 Max (UInt16 val1, UInt16 val2) {
return val1 > val2 ? val1 : val2;
}
public static UInt32 Max (UInt32 val1, UInt32 val2) {
return val1 > val2 ? val1 : val2;
}
public static UInt64 Max (UInt64 val1, UInt64 val2) {
return val1 > val2 ? val1 : val2;
}
}
In your main
method you can verify that you have compile-time certainty:
namespace TTTTTest
{
class Program
{
static void Main(string[] args)
{
long val1 = 5L;
long val2 = 10L;
Console.WriteLine(MaxMath.Max(val1, val2));
Console.Read();
}
}
}
I'll get ahead of one remark: no, this is not a violation of the DRY principle. The DRY principle is there to prevent people from duplicating code in multiple places that would cause the application to become hard to maintain.
This is not at all the case here: if you want a change then you can just change the template (a single source for all your generation!) and it's done.
In order to use it with your own custom definitions, add a namespace declaration (make sure it's the same one as the one where you'll define your own implementation) to your generated code and mark the class as partial
. Afterwards, add these lines to your template file so it will be included in the eventual compilation:
<#@ import namespace="TheNameSpaceYouWillUse" #>
<#@ assembly name="$(TargetPath)" #>
Let's be honest: This is pretty cool.
Disclaimer: this sample has been heavily influenced by Metaprogramming in .NET by Kevin Hazzard and Jason Bock, Manning Publications.
This little and simple trick I just learnt may help someone trying to avoid :before or :after pseudo elements altogether (for whatever reason) in changing text on hover. You can add both texts in the HTML, but vary the CSS 'display' property based on hover. Assuming the second text 'Add' has a class named 'add-label'; here is a little modification:
span.add-label{
display:none;
}
.item:hover span.align{
display:none;
}
.item:hover span.add-label{
display:block;
}
Here is a demonstration on codepen: https://codepen.io/ifekt/pen/zBaEVJ
You can not specify the password from the command line but you can do either using ssh keys or using sshpass
as suggested by John C. or using a expect
script.
To use sshpass, you need to install it first. Then
sshpass -f <(printf '%s\n' your_password) ssh user@hostname
instead of using sshpass -p your_password
. As mentioned by Charles Duffy
in the comments, it is safer to supply the password from a file or from a variable instead of from command line.
BTW, a little explanation for the <(command)
syntax. The shell executes the command inside the parentheses and replaces the whole thing with a file descriptor, which is connected to the command's stdout. You can find more from this answer https://unix.stackexchange.com/questions/156084/why-does-process-substitution-result-in-a-file-called-dev-fd-63-which-is-a-pipe
This means that Jupyter is still running the kernel. It is possible that you are running an infinite loop within the kernel and that is why it can't complete the execution.
Try manually stopping the kernel by pressing the stop button at the top. If that doesn't work, interrupt it and restart it by going to the "Kernel" menu. This should disconnect it.
Otherwise, I would recommend closing and reopening the notebook. The problem may also be with your code.
a {
display: block;
height: 20px;
width: auto;
border: 1px solid #000;
}
You can play with <a>
tags like this if you give them a block display. You can adjust the border to give a shade like effect and the background color for that button feel :)
A formula to have the range of values from 0 to 360 degrees.
f(x,y)=180-90*(1+sign(x))* (1-sign(y^2))-45*(2+sign(x))*sign(y)
-(180/pi())*sign(x*y)*atan((abs(x)-abs(y))/(abs(x)+abs(y)))
I found this question and discussion very helpful and wanted to show the solution I ended up with. It is based on the answer given by @DevangRathod, but I used jQuery and made a couple tweaks to it, so wanted to show a fully commented sample to help anyone else working on something similar. I originally had been using the HTML5 data-list element, but was dissatisfied with that solution since it removes options from the drop down list that don't match text typed in the box. In my application, I wanted the full list to always be available.
Fully functional demo here: https://jsfiddle.net/abru77mm/
HTML:
<!--
Most style elements I left to the CSS file, but some are here.
Reason being that I am actually calculating my width dynamically
in my application so when I dynamically formulate this HTML, I
want the width and all the factors (such as padding and border
width and margin) that go into determining the proper widths to
be controlled by one piece of code, so those pieces are done in
the in-line style. Otherwise I leave the styling to the CSS file.
-->
<div class="data-list-input" style="width:190px;">
<select class="data-list-input" style="width:190px;">
<option value=""><Free Form Text></option>
<option value="Male">Male</option>
<option value="Female">Female</option>
<!-- Note that though the select/option allows for a different
display and internal value, there is no such distinction in the
text box, so for all the options (except the "none" option) the
value and content of the option should be identical. -->

jQuery(function() {
//keep the focus on the input box so that the highlighting
//I'm using doesn't give away the hidden select box to the user
$('select.data-list-input').focus(function() {

});
//when selecting from the select box, put the value in the input box
$('select.data-list-input').change(function() {
$(this).siblings('input.data-list-input').val($(this).val());
});
//When editing the input box, reset the select box setting to "free
//form input". This is important to do so that you can reselect the
//option you had selected if you want to.
$('input.data-list-input').change(function() {
$(this).siblings('select.data-list-input').val('');
});
});

Any comments for improvement on my implementation welcome. Hope someone finds this helpful.
You can do it like this. It will only accept numeric values, and limit to 10 numbers as your wish.
<TextInput
style={styles.textInput}
keyboardType='numeric'
onChangeText={(text)=> this.onChanged(text)}
value={this.state.myNumber}
maxLength={10} //setting limit of input
/>
You can see the entered value by writing the following code in your page:
{this.state.myNumber}
In the onChanged() function the code look like this:
onChanged(text){
let newText = '';

I hope this is helpful to others.
Using aggregate function like below :
[
{$group: {_id : {book : '$book',address:'$addr'}, total:{$sum :1}}},
{$project : {book : '$_id.book', address : '$_id.address', total : '$total', _id : 0}}
]
it will give you result like following :
{
"total" : 1,
"book" : "book33",
"address" : "address90"
},
{
"total" : 1,
"book" : "book5",
"address" : "address1"
},
{
"total" : 1,
"book" : "book99",
"address" : "address9"
},
{
"total" : 1,
"book" : "book1",
"address" : "address5"
},
{
"total" : 1,
"book" : "book5",
"address" : "address2"
},
{
"total" : 1,
"book" : "book3",
"address" : "address4"
},
{
"total" : 1,
"book" : "book11",
"address" : "address77"
},
{
"total" : 1,
"book" : "book9",
"address" : "address3"
},
{
"total" : 1,
"book" : "book1",
"address" : "address15"
},
{
"total" : 2,
"book" : "book1",
"address" : "address2"
},
{
"total" : 3,
"book" : "book1",
"address" : "address1"
}
I didn't quite get your expected result format, so feel free to modify this to one you need.
I'm sorry to disagree, but according to the rules for parsing a legacy color value posted by @Yuhong Bao, chucknorris
DOES NOT equate to #CC0000
, but rather to #C00000
, a very similar but slightly different hue of red. I used the Firefox ColorZilla add-on to verify this.
The rules state:
chucknorris0
chuc knor ris0
ch kn ri
C0 00 00
I was able to use these rules to correctly interpret the following strings:
LuckyCharms
Luck
LuckBeALady
LuckBeALadyTonight
GangnamStyle
UPDATE: The original answerers who said the color was #CC0000
have since edited their answers to include the correction.
There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)
You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.
UNAME := $(shell uname -m)
all:
$(info Checking if custom header is needed)
ifeq ($(UNAME), x86_64)
... do some things to build unistd_32.h
endif
@make -C $(KDIR) M=$(PWD) modules
So you want unistd_32.h built (maybe) before you invoke the second make
, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:
ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif
all:
@make -C $(KDIR) M=$(PWD) modules
unistd_32.h:
... do some things to build unistd_32.h
Now for building unistd_32.h
:
F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
$(info Copying custom header)
$(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else
F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
ifeq ($(F2_EXISTS), 1)
$(info Copying custom header)
$(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
else
$(error asm/unistd_32.h and asm-386/unistd.h does not exist)
endif
endif
You are trying to build unistd.h
from unistd_32.h
; the only trick is that unistd_32.h
could be in either of two places. The simplest way to clean this up is to use a vpath
directive:
vpath unistd.h /usr/include/asm /usr/include/asm-i386
unistd_32.h: unistd.h
sed -e 's/__NR_/__NR32_/g' $< > $@
Old post but ES6 now handles this out of the box with the includes
method.
let files = ['file.json', 'other.js'];
let jsonFiles = files.filter(file => file.includes('.json'));
console.log("Files: ", jsonFiles) ==> //file.json
This took a while to get right. I had this issue when cross-compiling in Ubuntu for an ARM target. I solved it with:
PATH=$PATH:/ccpath/bin CC=ccname-gcc AR=ccname-ar LD=ccname-ld CPPFLAGS="-nostdinc -I/ccrootfs/usr/include ..." LDFLAGS=-L/ccrootfs/usr/lib ./autogen.sh --build=`config.guess` --host=armv5tejl-unknown-linux-gnueabihf
Notice CFLAGS is not used with autogen.sh/configure, using it gave me the error: "configure: error: C compiler cannot create executables". In the build environment I was using an autogen.sh script was provided, if you don't have an autogen.sh script substitute ./autogen.sh with ./configure in the command above. I ran config.guess on the target system to get the --host parameter.
After successfully running autogen.sh/configure, compile with:
PATH=$PATH:/ccpath/bin CC=ccname-gcc AR=ccname-ar LD=ccname-ld CPPFLAGS="-nostdinc -I/ccrootfs/usr/include ..." LDFLAGS=-L/ccrootfs/usr/lib CFLAGS="-march=... -mcpu=... etc." make
The CFLAGS I chose to use were: "-march=armv5te -fno-tree-vectorize -mthumb-interwork -mcpu=arm926ej-s". It will take a while to get all of the include directories set up correctly: you might want some includes pointing to your cross-compiler and some pointing to your root file system includes, and there will likely be some conflicts.
I'm sure this is not the perfect answer. And I am still seeing some include directories pointing to / and not /ccrootfs in the Makefiles. Would love to know how to correct this. Hope this helps someone.

The example from MySQL documentation http://dev.mysql.com/doc/refman/5.1/en/problems-with-float.html (i shrink it, documentation for this section is the same for 5.5)
mysql> create table t1 (i int, d1 double, d2 double);
mysql> insert into t1 values (2, 0.00 , 0.00),
(2, -13.20, 0.00),
(2, 59.60 , 46.40),
(2, 30.40 , 30.40);
mysql> select
i,
sum(d1) as a,
sum(d2) as b
from
t1
group by
i
having a <> b; -- a != b
+------+-------------------+------+
| i | a | b |
+------+-------------------+------+
| 2 | 76.80000000000001 | 76.8 |
+------+-------------------+------+
1 row in set (0.00 sec)
Basically if you sum a you get 0-13.2+59.6+30.4 = 76.8. If we sum up b we get 0+0+46.4+30.4=76.8. The sum of a and b is the same but MySQL documentation says:
A floating-point value as written in an SQL statement may not be the same as the value represented internally.
If we repeat the same with decimal:
mysql> create table t2 (i int, d1 decimal(60,30), d2 decimal(60,30));
Query OK, 0 rows affected (0.09 sec)
mysql> insert into t2 values (2, 0.00 , 0.00),
(2, -13.20, 0.00),
(2, 59.60 , 46.40),
(2, 30.40 , 30.40);
Query OK, 4 rows affected (0.07 sec)
Records: 4 Duplicates: 0 Warnings: 0
mysql> select
i,
sum(d1) as a,
sum(d2) as b
from
t2
group by
i
having a <> b;
Empty set (0.00 sec)
The result as expected is empty set.
So as long you do not perform any SQL arithemetic operations you can use DOUBLE, but I would still prefer DECIMAL.
Another thing to note about DECIMAL is rounding if fractional part is too large. Example:
mysql> create table t3 (d decimal(5,2));
Query OK, 0 rows affected (0.07 sec)
mysql> insert into t3 (d) values(34.432);
Query OK, 1 row affected, 1 warning (0.10 sec)
mysql> show warnings;
+-------+------+----------------------------------------+
| Level | Code | Message |
+-------+------+----------------------------------------+
| Note | 1265 | Data truncated for column 'd' at row 1 |
+-------+------+----------------------------------------+
1 row in set (0.00 sec)
mysql> select * from t3;
+-------+
| d |
+-------+
| 34.43 |
+-------+
1 row in set (0.00 sec)
You can use the focusout event to detect keyboard dismissal. It's like blur, but bubbles. It will fire when the keyboard closes (but also in other cases, of course). In Safari and Chrome the event can only be registered with addEventListener, not with legacy methods. Here is an example I used to restore a Phonegap app after keyboard dismissal.
document.addEventListener('focusout', function(e) {window.scrollTo(0, 0)});
Without this snippet, the app container stayed in the up-scrolled position until page refresh.
