df['binned'] = pd.cut(df['percentage'], bins)
print (df)
percentage binned
0 46.50 (25, 50]
1 44.20 (25, 50]
2 100.00 (50, 100]
3 42.12 (25, 50]
bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
df['binned'] = pd.cut(df['percentage'], bins=bins, labels=labels)
print (df)
percentage binned
0 46.50 5
1 44.20 5
2 100.00 6
3 42.12 5
bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = np.searchsorted(bins, df['percentage'].values)
print (df)
percentage binned
0 46.50 5
1 44.20 5
2 100.00 6
3 42.12 5
...and then value_counts
or groupby
and aggregate size
:
s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50] 3
(50, 100] 1
(10, 25] 0
(5, 10] 0
(1, 5] 0
(0, 1] 0
Name: percentage, dtype: int64
s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1] 0
(1, 5] 0

Series
methods like Series.value_counts()

After your comments this actually makes perfect sense why you don't get a histogram of each different value. There are 1.4 million rows, and ten discrete buckets. So apparently each bucket is exactly 10% (to within what you can see in the plot).
A quick rerun of your data:
In [25]: df.hist(column='Trip_distance')
Prints out absolutely fine.
The df.hist
function comes with an optional keyword argument bins=10
which buckets the data into discrete bins. With only 10 discrete bins and a more or less homogeneous distribution of hundreds of thousands of rows, you might not be able to see the difference in the ten different bins in your low resolution plot:
In [34]: df.hist(column='Trip_distance', bins=50)

As other users said, the best way for Windows users is to set the global environment variable.
I install the Miniconda3 for MXNet.
Before I do something, only Anaconda Prompt works for conda

After setting the global environment variable, The CMD and Git Bash work. But in some IDEs like RStudio, the nested Git Bash doesn't work.
After restarting my computer, the Git Bash in the RStudio works for conda
.
I hope these tests helps for you.

I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.
Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.
Here is an attempt at this with your data:
import matplotlib.pyplot as plt
# ... define 2D array hist as you did
plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case
I bet for sure, that this is because you didn't close the running instance of the program before trying to re-compile it.
Generally, ld.exe
returns 1 when it can't access required files. This usually includes
Access denied
)The program looks completely fine, so the second point should not hit. In usual cases, it's impossible for ld
to fail to open the object file (unless you have a faulty drive and a dirty filesystem), so the first point is also nearly impossible.
Now we get to the third point. Note that Windows not allow writing to a file when it's in use, so the running instance of your program prevents ld.exe
from writing the new linked program to it.
So next time be sure to close running programs before compiling.
You can check data type of variable.
N = [2,3,5]
P = 5
type(P)
It will give you out put as data type of P.
<type 'int'>
So that you can differentiate that it is an integer or an array.

A bin is range that represents the width of a single bar of the histogram along the X-axis. You could also call this the interval. (Wikipedia defines them more formally as "disjoint categories".)
The Numpy histogram
function doesn't draw the histogram, but it computes the occurrences of input data that fall within each bin, which in turns determines the area (not necessarily the height if the bins aren't of equal width) of each bar.
In this example:
np.histogram([1, 2, 1], bins=[0, 1, 2, 3])
There are 3 bins, for values ranging from 0 to 1 (excl 1.), 1 to 2 (excl. 2) and 2 to 3 (incl. 3), respectively. The way Numpy defines these bins if by giving a list of delimiters ([0, 1, 2, 3]
) in this example, although it also returns the bins in the results, since it can choose them automatically from the input, if none are specified. If bins=5
, for example, it will use 5 bins of equal width spread between the minimum input value and the maximum input value.
The input values are 1, 2 and 1. Therefore, bin "1 to 2" contains two occurrences (the two 1
values), and bin "2 to 3" contains one occurrence (the 2
). These results are in the first item in the returned tuple: array([0, 2, 1])
.
Since the bins here are of equal width, you can use the number of occurrences for the height of each bar. When drawn, you would have:
You can plot this directly with Matplotlib (its hist
function also returns the bins and the values):
>>> import matplotlib.pyplot as plt
>>> plt.hist([1, 2, 1], bins=[0, 1, 2, 3])
(array([0, 2, 1]), array([0, 1, 2, 3]), <a list of 3 Patch objects>)
>>> plt.show()
url=”http://shahkrunalm.wordpress.com“
content=”$(curl -sLI “$url” | grep HTTP/1.1 | tail -1 | awk {‘print $2'})”
if [ ! -z $content ] && [ $content -eq 200 ]
then
echo “valid url”
else
echo “invalid url”
fi
If you want to see the array as an array, you can say
alert(JSON.stringify(aCustomers));
instead of all those document.write
s.
However, if you want to display them cleanly, one per line, in your popup, do this:
alert(aCustomers.join("\n"));
Here is another solution using only matplotlib.pyplot
and numpy
packages.
It works only for Gaussian fitting. It is based on maximum likelihood estimation and have already been mentioned in this topic.
Here is the corresponding code :
# Python version : 2.7.9
from __future__ import division
import numpy as np
from matplotlib import pyplot as plt
# For the explanation, I simulate the data :
N=1000
data = np.random.randn(N)
# But in reality, you would read data from file, for example with :
#data = np.loadtxt("data.txt")
# Empirical average and variance are computed
avg = np.mean(data)
var = np.var(data)
# From that, we know the shape of the fitted Gaussian.
pdf_x = np.linspace(np.min(data),np.max(data),100)
pdf_y = 1.0/np.sqrt(2*np.pi*var)*np.exp(-0.5*(pdf_x-avg)**2/var)
# Then we plot :
plt.figure()
plt.hist(data,30,normed=True)
plt.plot(pdf_x,pdf_y,'k--')
plt.legend(("Fit","Data"),"best")
plt.show()
and here is the output.
I had this same problem.
Did:
f1 = plt.figure(1)
# code for figure 1
# don't write 'plt.show()' here
f2 = plt.figure(2)
# code for figure 2
plt.show()
Write 'plt.show()' only once, after the last figure.
Worked for me.
in case someone got stuck with this and none of the answers above worked, below is what worked for me. Hope it helps.
var oldString = "\\r|\\n";
// None of these worked for me
// var newString = oldString(@"\\", @"\");
// var newString = oldString.Replace("\\\\", "\\");
// var newString = oldString.Replace("\\u5b89", "\u5b89");
// var newString = Regex.Replace(oldString , @"\\", @"\");
// This is what worked
var newString = Regex.Unescape(oldString);
// newString is now "\r|\n"
For N bins, the bin edges are specified by list of N+1 values where the first N give the lower bin edges and the +1 gives the upper edge of the last bin.
Code:
from numpy import np; from pylab import *
bin_size = 0.1; min_edge = 0; max_edge = 2.5
N = (max_edge-min_edge)/bin_size; Nplus1 = N + 1
bin_list = np.linspace(min_edge, max_edge, Nplus1)
Note that linspace produces array from min_edge to max_edge broken into N+1 values or N bins
As a completion to Gustavo Bezerra's answer:
If you want each histogram to be normalized (normed
for mpl<=2.1 and density
for mpl>=3.1) you cannot just use normed/density=True
, you need to set the weights for each value instead:
import numpy as np
import matplotlib.pyplot as plt
x = np.random.normal(1, 2, 5000)
y = np.random.normal(-1, 3, 2000)
x_w = np.empty(x.shape)
x_w.fill(1/x.shape[0])
y_w = np.empty(y.shape)
y_w.fill(1/y.shape[0])
bins = np.linspace(-10, 10, 30)
plt.hist([x, y], bins, weights=[x_w, y_w], label=['x', 'y'])
plt.legend(loc='upper right')
plt.show()
As a comparison, the exact same x
and y
vectors with default weights and density=True
:
Another alternative is to use the ufunc.at. This method applies in-place a desired operation at specified indices. We can get the bin position for each datapoint using the searchsorted method. Then we can use at to increment by 1 the position of histogram at the index given by bin_indexes, every time we encounter an index at bin_indexes.
np.random.seed(1)
data = np.random.random(100) * 100
bins = np.linspace(0, 100, 10)
histogram = np.zeros_like(bins)
bin_indexes = np.searchsorted(bins, data)
np.add.at(histogram, bin_indexes, 1)
This might be useful for someone.
Numpy's histogram function returns the edges of each bin, rather than the value of the bin. This makes sense for floating-point numbers, which can lie within an interval, but may not be the desired result when dealing with discrete values or integers (0, 1, 2, etc). In particular, the length of bins returned from np.histogram is not equal to the length of the counts / density.
To get around this, I used np.digitize to quantize the input, and count the fraction of counts for each bin. You could easily edit to get the integer number of counts.
def compute_PMF(data):
import numpy as np
from collections import Counter
_, bins = np.histogram(data, bins='auto', range=(data.min(), data.max()), density=False)
h = Counter(np.digitize(data,bins) - 1)
weights = np.asarray(list(h.values()))
weights = weights / weights.sum()
values = np.asarray(list(h.keys()))
return weights, values
####

Maybe try something like:
import matplotlib.pyplot as plt
import numpy
from scipy import stats
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = stats.kde.gaussian_kde(data)
x = numpy.arange(0., 8, .1)
plt.plot(x, density(x))
plt.show()
You can easily replace gaussian_kde()
by a different kernel density estimate.
Why use GROUP BY at all?

for i in range(19):
plt.subplot(5,4,i+1)
It plots 19 total graphs on one page. The format is 5 down and 4 across..
Not to necro but I made this which can determine pixels based on a variety of values:
$.fn.extend({
pixels: function (property, base) {
var value = $(this).css(property);
var original = value;
var outer = property.indexOf('left') != -1 || property.indexOf('right') != -1
? $(this).parent().outerWidth()
: $(this).parent().outerHeight();
// EM Conversion Factor
base = base || 16;
if (value == 'auto' || value == 'inherit')
return outer || 0;
value = value.replace('rem', '');
value = value.replace('em', '');
if (value !== original) {
value = parseFloat(value);
return value ? base * value : 0;
}
value = value.replace('pt', '');
if (value !== original) {
value = parseFloat(value);
return value ? value * 1.333333 : 0; // 1pt = 1.333px
}
value = value.replace('%', '');
if (value !== original) {
value = parseFloat(value);
return value ? (outer * value / 100) : 0;
}
value = value.replace('px', '');
return parseFloat(value) || 0;
}
});
This way, we take into account for sizing, and auto / inherit.

Tom is correct in describing exactly what the + operator does. It creates a temporary StringBuilder
, appends the parts, and finishes with toString()
.
However, all of the answers so far are ignoring the effects of HotSpot runtime optimizations. Specifically, these temporary operations are recognized as a common pattern and are replaced with more efficient machine code at run-time.
@marcio: You've created a micro-benchmark; with modern JVM's this is not a valid way to profile code.
The reason run-time optimization matters is that many of these differences in code -- even including object-creation -- are completely different once HotSpot gets going. The only way to know for sure is profiling your code in situ.
Finally, all of these methods are in fact incredibly fast. This might be a case of premature optimization. If you have code that concatenates strings a lot, the way to get maximum speed probably has nothing to do with which operators you choose and instead the algorithm you're using!

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between
BEGIN
SELECT MONTH(CURDATE()) INTO @curmonth;
SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
SELECT DAY(@checkweekday) INTO @checkday;
SET @daycount = 0;
SET @workdays = 0;
WHILE(@daycount < @totaldays) DO
IF (WEEKDAY(@checkweekday) < 5) THEN
SET @workdays = @workdays+1;
END IF;
SET @daycount = @daycount+1;
SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
END WHILE;
END
Just for others:
If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query
delimiter ;;
drop procedure if exists test2;;
create procedure test2()
begin
select ‘Hello World’;
end
;;
Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.
The first_day function you need is: How to get first day of every corresponding month in mysql?
Showing the Procedure is working Simply add the following line below END WHILE and above END
SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;
Then use the following code in the SQL Query Window.
call test2 /* or whatever you changed the name of the stored procedure to */
NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

To be able to create a relation, the table Storage Engine must be InnoDB. You can edit in Operations tab.
Then, you need to be sure that the id column in your main table has been indexed. It should appear at Index section in Structure tab.
Finally, you could see the option Relations View in Structure tab. When edditing, you will be able to select the parent column in foreign table to create the relation.
See attachments. I hope this could be useful for anyone.
Switching to AndroidX helped me:
import androidx.appcompat.app.AppCompatActivity;
The way of dknaack does not work for me, I found this solution as well:
@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList,
"Select chapter", new { @onchange = "location = this.value;" })
where
@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)
In the controller you can add:
DbModel db = new DbModel(); //entity model of Entity Framework
ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");
To amend SDP's answer above, you do NOT need to declarecol-xs-12
in <div class="col-xs-12 col-sm-6">
. Bootstrap 3 is mobile-first, so every div column is assumed to be a 100% width div by default - which means at the "xs" size it is 100% width, it will always default to that behavior regardless of what you set at sm, md, lg
. If you want your xs
columns to be not 100%, then you normally do a col-xs-(1-11)
.
It just means that the server cannot find your image.
Remember The image path must be relative to the CSS file location
Check the path and if the image file exist.
Yes you can convert it back. You can try:
date("Y-m-d H:i:s", 1388516401);
The logic behind this conversion from date to an integer is explained in strtotime in PHP:
The function expects to be given a string containing an English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.
For example, strtotime("1970-01-01 00:00:00")
gives you 0 and strtotime("1970-01-01 00:00:01")
gives you 1.
This means that if you are printing strtotime("2014-01-01 00:00:01")
which will give you output 1388516401
, so the date 2014-01-01 00:00:01
is 1,388,516,401 seconds after January 1 1970 00:00:00 UTC.
Try adding a header() call before sending headers, like:
header('X-Powered-By: Our company\'s development team');
regardless of the expose_php setting in php.ini
Note: This worked in the past and I received many up votes. Perhaps this is not a solution anymore - but it once was - as the eclipse version was indicated.
This can also be caused by a Java Build Path Problem.
In my case, I had a an error:
A cycle was detected in the build path of project {project}. The cycle consists of projects {x, y, z}.
This can occur when you include other projects in the build path of the project you wish to run. In fact, all the projects will fail to run with the error
Could not find the main class: Example.class
Windows
-> Preferences
-> Java
-> Compiler
-> Building
-> Build Path Problems
Abort build when build path errors occur
toggleThis seems like a can of worms if you end up with other build path errors I image. So use with caution.
I found the solution to this here
Info
My approach:
define a default constraint on the ModDate
column with a value of GETDATE()
- this handles the INSERT
case
have a AFTER UPDATE
trigger to update the ModDate
column
Something like:
CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
UPDATE dbo.TimeEntry
SET ModDate = GETDATE()
WHERE ID IN (SELECT DISTINCT ID FROM Inserted)
If you really need tabs copy a tab from word or notepad and paste it in the text box where you want it
1 2 3
12 22 33
Unfortunately I think they remove the tabs from these comments though :) It will show as %09 in your POST or GET
The accepted answer is awesome. However, you can still use %
width and attain text-overflow: ellipsis
. The solution is simple:
display: inline-block; /* for em, a, span, etc (inline by default) */
text-overflow: ellipsis;
width: calc (80%); /* The trick is here! */
It seems whenever you use calc
, the final value is rendered in absolute pixels, which consequentially converts 80%
to something like 800px
for a 1000px
-width container. Therefore, instead of using width: [YOUR PERCENT]%
, use width: calc([YOUR PERCENT]%)

"""Print a field specified by row, column numbers from given csv file.

Note: list(csv.reader(f))

Assuming that you want different names for the tables.
If you are using PHPmyadmin you can use their SQL option in the menu. Then you simply copy the SQL-code from the first table and paste it into the new table.
That worked out for me when I was moving from localhost to a webhost. Hope it works for you!
I've tested all anwers, but they were all too slow for me. If you have Excel installed you can use the COM.
I thought initially it would be slower since it will load everything for the actual Excel application, but it isn't for huge files. Maybe because the algorithm for opening and saving files runs a heavily optimized compiled code, Microsoft guys make a lot of money for it after all.
import sys
import os
import glob
from win32com.client import Dispatch
def main(path):
excel = Dispatch("Excel.Application")
if is_full_path(path):
process_file(excel, path)
else:
files = glob.glob(path)
for file_path in files:
process_file(excel, file_path)
excel.Quit()
def process_file(excel, path):
fullpath = os.path.abspath(path)
full_csv_path = os.path.splitext(fullpath)[0] + '.csv'
workbook = excel.Workbooks.Open(fullpath)
workbook.Worksheets(1).SaveAs(full_csv_path, 6)
workbook.Saved = 1
workbook.Close()
def is_full_path(path):
return path.find(":") > -1
if __name__ == '__main__':
main(sys.argv[1])
This is very raw code and won't check for errors, print help or anything, it will just create a csv file for each file that matches the pattern you entered in the function so you can batch process a lot of files only launching excel application once.
To provide POST
parameter send your parameter as JSONObject
in to the JsonObjectRequest
constructor. 3rd parameter accepts a JSONObject
that is used in Request body.
JSONObject paramJson = new JSONObject();
paramJson.put("key1", "value1");
paramJson.put("key2", "value2");
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,url,paramJson,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(jsonObjectRequest);

This whole layout will be your search bar
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="35dp"
android:layout_margin="10dp"
android:background="@drawable/your_desired_drawable">
<EditText
android:id="@+id/search_et"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:layout_toStartOf="@id/clear_btn"
android:background="@null"
android:hint="search..."
android:imeOptions="actionSearch"
android:inputType="text"
android:maxLines="1"
android:paddingStart="15dp"

Now this is the functionality of clear button, paste this code in onCreate method.
search_et.addTextChangedListener(object: TextWatcher {

I have hit this page frequently when looking for a way to export a git repository. My answer to this question considers three properties that svn export has by design compared to git, since svn follows a centralized repository approach:
Exporting a certain branch using svn is accomplished by specifying the appropriate path
git clone --depth 1 --branch master git://git.somewhere destination_path
rm -rf destination_path/.git
When building a certain release it is useful to clone a stable branch as for example --branch stable
or --branch release/0.9
.
Two things you can do, return an object
somethingAsync()
.then( afterSomething )
.then( afterSomethingElse );
function processAsync (amazingData) {
//processSomething
return {
amazingData: amazingData,
processedData: processedData
};
}
function afterSomething( amazingData ) {
return processAsync( amazingData );
}
function afterSomethingElse( dataObj ) {
let amazingData = dataObj.amazingData,
processedData = dataObj.proccessedData;
}
Use the scope!
var amazingData;
somethingAsync()
.then( afterSomething )
.then( afterSomethingElse )
function afterSomething( returnedAmazingData ) {
amazingData = returnedAmazingData;
return processAsync( amazingData );
}
function afterSomethingElse( processedData ) {
//use amazingData here
}
You could do something like this
var today = new Date();
var startDay = 0;
var weekStart = new Date(today.getDate() - (7 + today.getDay() - startDay) % 7);
var weekEnd = new Date(today.getDate() + (7 - today.getDay() - startDay) % 7);
Where startDay
is a number from 0 to 6 where 0 stands for Sunday (ie 1 = Monday, 2 = Tuesday, etc).

Hmm... Looking for better way... here it is
var onlyUrl = window.location.href.replace(window.location.search,'');
The besty practice is to use '/' and a so called 'raw string' to define file path in Python.
path = r"C:/Test.py"
However, a normal program may not have the permission to write in the C:
drive root directory. You may need to allow your program to do so, or choose something more reasonable since you probably not need to do so.
Foo
variable will never ever take up memory.using
statement simply calls dispose on an IDisposable
object when it exits, so this is equivalent to your second bullet point. Both will indicate that you are done with the object and tell the GC that you are ready to let go of it. Overwriting the only reference to the object will have a similar effect.Atomic property can be accessed by only one thread at a time. It is thread safe. Default is atomic .Please note that there is no keyword atomic
Nonatomic means multiple thread can access the item .It is thread unsafe
So one should be very careful while using atomic .As it affect the performance of your code
If using STS, you can in Eclipse mark the configuration file as "Bean Configuration" file (you can specify that when creating or on right click on a XML file):
You project has to have Spring Nature (right click on maven project for example):
then spring.xml
is opened by default with Spring Config Editor
and this editor has Namespaces tab
Which enables you to specify the namespaces:
Please be aware, that it depends on dependencies (using maven project), so if spring-tx
is not defined in maven's pom.xml, option is not there, which prevents you to have The matching wildcard is strict, but no declaration can be found for element 'tx:annotation-driven' 'context:component-scan' problem...

To avoid the window losing focus when its returning to visible after being hidden all that is needed is:
setExtendedState(JFrame.NORMAL);
Like so:
defaultItem.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
showWindow();
setExtendedState(JFrame.NORMAL);
}
});
I liked codebender's answer, but needed it to work in C++/CLI. This is what I ended up with. There's no LINQ usage, but works.
generic <typename T> T MyClass::ReadAppSetting(String^ searchKey, T defaultValue) {
for each (String^ setting in ConfigurationManager::AppSettings->AllKeys) {
if (setting->Equals(searchKey)) { // if the key is in the app.config
try { // see if it can be converted
auto converter = TypeDescriptor::GetConverter((Type^)(T::typeid));
if (converter != nullptr) { return (T)converter->ConvertFromString(ConfigurationManager::AppSettings[searchKey]); }
} catch (Exception^ ex) {} // nothing to do
}
}
return defaultValue;
}
In my application i have component and all data is coming from API which i am calling in Component's constructor. There is button by which i am updating my page data. on button click i have save data in back end and refresh data. So to reload/refresh the component - as per my requirement - is only to refresh the data. if this is also your requirement then use the same code written in constructor of component.
Either $(())
or $[]
will work for computing the result of an arithmetic operation. You're using $()
which is simply taking the string and evaluating it as a command. It's a bit of a subtle distinction. Hope this helps.
As tink pointed out in the comments on this answer, $[]
is deprecated, and $(())
should be favored.

Sometimes you get broken code, when using dex2jar
/apktool
, most notably in loops. To avoid this, use jadx, which decompiles dalvik bytecode into java source code, without creating a .jar
/.class
file first as dex2jar
does (apktool uses dex2jar I think). It is also open-source and in active development. It even has a GUI, for GUI-fanatics. Try it!

You can easily write the method to do that :
public static String toCamelCase(final String init) {
if (init == null)
return null;
final StringBuilder ret = new StringBuilder(init.length());
for (final String word : init.split(" ")) {
if (!word.isEmpty()) {
ret.append(Character.toUpperCase(word.charAt(0)));
ret.append(word.substring(1).toLowerCase());
}
if (!(ret.length() == init.length()))
ret.append(" ");
}
return ret.toString();
}
The character 0x0C is be invalid in XML 1.0 but would be a valid character in XML 1.1. So unless the xml file specifies the version as 1.1 in the prolog it is simply invalid and you should complain to the producer of this file.
The Internationalization API supports getting the user timezone, and is supported in all current browsers.
console.log(Intl.DateTimeFormat().resolvedOptions().timeZone)
_x000D_
Keep in mind that on some older browser versions that support the Internationalization API, the timeZone
property is set to undefined
rather than the user’s timezone string. As best as I can tell, at the time of writing (July 2017) all current browsers except for IE11 will return the user timezone as a string.
I would use .Equals()
for comparison instead of ==
.
Like so:
MyClass item = MyList.Find(item => item.name.Equals("foo"));
Particularly because it gives you options like StringComparison, which is awesome. Example:
MyClass item = MyList.Find(item => item.name.Equals("foo", StringComparison.InvariantCultureIgnoreCase);
This enables your code to ignore special characters, upper and lower case. There are more options.
In case you want to do it programmatically,
checkBoxOrRadioButton.setButtonDrawable(null);
checkBoxOrRadioButton.setBackgroundResource(R.drawable.resource_name);
Basically, tree conflicts arise if there is some restructure in the folder structure on the branch.
You need to delete the conflict folder and use svn clean
once.
Hope this solves your conflict.
MSVC 2010 solution, since it doesn't support std::initializer_list<>

const char *args[] = {"hello", "world!"};
std::vector<std::string> v(args, std::end(args));
Change the onclick from
onclick="javascript:SubmitFrm()"
to
onclick="SubmitFrm()"
I was using a simple call instead of async
. As soon I added await
and made method async
it started working fine.
public async Task<T> ExecuteScalarAsync<T>(string query, object parameter = null, CommandType commandType = CommandType.Text) where T : IConvertible
{
using (IDbConnection db = new SqlConnection(_con))
{
return await db.ExecuteScalarAsync<T>(query, parameter, null, null, commandType);
}
}
It seems that you catch not the exception you wanna catch out there :)
if the s
is a socket.socket()
object, then the right way to call .connect
would be:
import socket
s = socket.socket()
address = '127.0.0.1'
port = 80 # port number is a number, not string
try:
s.connect((address, port))
# originally, it was
# except Exception, e:
# but this syntax is not supported anymore.
except Exception as e:
print("something's wrong with %s:%d. Exception is %s" % (address, port, e))
finally:
s.close()
Always try to see what kind of exception is what you're catching in a try-except loop.
You can check what types of exceptions in a socket module represent what kind of errors (timeout, unable to resolve address, etc) and make separate except
statement for each one of them - this way you'll be able to react differently for different kind of problems.
Change maxDate to current date
maxDate: new Date()
It will set current date as maximum value.
First of all, the provided long code:

Now, to your question:
how to compare two elements coming from xml as string
In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator =
and the function not()
together with the operator =
.
$str1 = $str2
evaluates to true()
exactly when the string $str1
is equal to the string $str2
.
not($str1 = $str2)
evaluates to true()
exactly when the string $str1
is not equal to the string $str2
.
There is also the !=
operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.
Now, the rules for comparing two element nodes are similar:
$el1 = $el2
evaluates to true()
exactly when the string value of $el1
is equal to the string value of $el2
.
not($el1 = $el2)
evaluates to true()
exactly when the string value of $el1
is not equal to the string value of $el2
.
However, if one of the operands of =
is a node-set, then
$ns = $str
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string $str
$ns1 = $ns2
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string value of some node from $ns2
Therefore, the expression:
OU_NAME='OU_ADDR1'
evaluates to true()
only when there is at least one element child of the current node that is named OU_NAME
and whose string value is the string 'OU_ADDR1'.
This is obviously not what you want!
Most probably you want:
OU_NAME=OU_ADDR1
This expression evaluates to true
exactly there is at least one OU_NAME
child of the current node and one OU_ADDR1
child of the current node with the same string value.
Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt
, le
, eq
, gt
, ge
and the inherited from XPath 1.0 general comparison operator =
.
Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.
You don't need to convert it. List<T>
implements the IEnumerable<T>
interface so it is already an enumerable.
This means that it is perfectly fine to have the following:
public IEnumerable<Book> GetBooks()
{
List<Book> books = FetchEmFromSomewhere();
return books;
}
as well as:
public void ProcessBooks(IEnumerable<Book> books)
{
// do something with those books
}
which could be invoked:
List<Book> books = FetchEmFromSomewhere();
ProcessBooks(books);
For anyone else who lands here I'd like to add on to Günter Zöchbauer's answer this was my solution for implementing a utility to know if there's internet or not regardless of anything else.
Disclaimer:
I'm new to both Dart and Flutter so this may not be the best approach, but would love to get feedback.
My requirements
I didn't want to have a bunch of repeated code anywhere I needed to check the connection and I wanted it to automatically update components or anything else that cared about the connection whenever there was a change.
First we setup a Singleton. If you're unfamiliar with this pattern there's a lot of good info online about them. But the gist is that you want to make a single instance of a class during the application life cycle and be able to use it anywhere.
This singleton hooks into flutter_connectivity
and listens for connectivity changes, then tests the network connection, then uses a StreamController
to update anything that cares.
It looks like this:
import 'dart:io'; //InternetAddress utility
import 'dart:async'; //For StreamController/Stream
import 'package:connectivity/connectivity.dart';
class ConnectionStatusSingleton {
//This creates the single instance by calling the `_internal` constructor specified below
static final ConnectionStatusSingleton _singleton = new ConnectionStatusSingleton._internal();
ConnectionStatusSingleton._internal();
//This is what's used to retrieve the instance through the app
static ConnectionStatusSingleton getInstance() => _singleton;
//This tracks the current connection status
bool hasConnection = false;
//This is how we'll allow subscribing to connection changes
StreamController connectionChangeController = new StreamController.broadcast();
//flutter_connectivity
final Connectivity _connectivity = Connectivity();
//Hook into flutter_connectivity's Stream to listen for changes
//And check the connection status out of the gate
void initialize() {
_connectivity.onConnectivityChanged.listen(_connectionChange);
checkConnection();
}
Stream get connectionChange => connectionChangeController.stream;
//A clean up method to close our StreamController
// Because this is meant to exist through the entire application life cycle this isn't
// really an issue
void dispose() {
connectionChangeController.close();
}
//flutter_connectivity's listener
void _connectionChange(ConnectivityResult result) {
checkConnection();
}
//The test to actually see if there is a connection
Future<bool> checkConnection() async {
bool previousConnection = hasConnection;
try {
final result = await InternetAddress.lookup('google.com');
if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
hasConnection = true;
} else {
hasConnection = false;
}
} on SocketException catch(_) {
hasConnection = false;
}
//The connection status changed send out an update to all listeners
if (previousConnection != hasConnection) {
connectionChangeController.add(hasConnection);
}
return hasConnection;
}
}
Initialization
First we have to make sure we call the initialize of our singleton. But only once.
This parts up to you but I did it in my app's main()
:
void main() {
ConnectionStatusSingleton connectionStatus = ConnectionStatusSingleton.getInstance();
connectionStatus.initialize();
runApp(MyApp());
//Call this if initialization is occuring in a scope that will end during app lifecycle
//connectionStatus.dispose();
}
In Widget
or elsewhere
import 'dart:async'; //For StreamSubscription
...
class MyWidgetState extends State<MyWidget> {
StreamSubscription _connectionChangeStream;
bool isOffline = false;
@override
initState() {
super.initState();
ConnectionStatusSingleton connectionStatus = ConnectionStatusSingleton.getInstance();
_connectionChangeStream = connectionStatus.connectionChange.listen(connectionChanged);
}
void connectionChanged(dynamic hasConnection) {
setState(() {
isOffline = !hasConnection;
});
}
@override
Widget build(BuildContext ctxt) {
...
}
}
Hope somebody else finds this useful!

Toggle airplane mode in the emulator to see the result
This is my aproach:
and any size numbers
private void numeroCuenta_TextChanged(object sender, EventArgs e)
{
string org = numeroCuenta.Text;
string formated = string.Concat(org.Where(c => (c >= '0' && c <= '9')));
if (formated != org)
{
int s = numeroCuenta.SelectionStart;
if (s > 0 && formated.Length > s && org[s - 1] != formated[s - 1]) s--;
numeroCuenta.Text = formated;
numeroCuenta.SelectionStart = s;
}
}
//create and fill polygon
CanvasRenderingContext2D.prototype.fillPolygon = function (pointsArray, fillColor, strokeColor) {
if (pointsArray.length <= 0) return;
this.moveTo(pointsArray[0][0], pointsArray[0][1]);
for (var i = 0; i < pointsArray.length; i++) {
this.lineTo(pointsArray[i][0], pointsArray[i][1]);
}
if (strokeColor != null && strokeColor != undefined)
this.strokeStyle = strokeColor;
if (fillColor != null && fillColor != undefined) {
this.fillStyle = fillColor;
this.fill();
}
}
//And you can use this method as
var polygonPoints = [[10,100],[20,75],[50,100],[100,100],[10,100]];
context.fillPolygon(polygonPoints, '#F00','#000');
Following from Ryan's answer, I think that the interface you are looking for is defined as follows:
interface Param {
title: string;
callback: () => void;
}
In Windows, this worked from an administrative prompt:
C:\Python27\Lib\site-packages\requests*
easy_install requests==2.3
pip install --upgrade pip
pip install --upgrade requests
A public item is one that is accessible from any other class. You just have to know what object it is and you can use a dot operator to access it. Protected means that a class and its subclasses have access to the variable, but not any other classes, they need to use a getter/setter to do anything with the variable. A private means that only that class has direct access to the variable, everything else needs a method/function to access or change that data. Hope this helps.
I am so glad to solve this problem:
HttpPost httppost = new HttpPost(postData);
CookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID", getSessionId());
//cookie.setDomain("your domain");
cookie.setPath("/");
cookieStore.addCookie(cookie);
client.setCookieStore(cookieStore);
response = client.execute(httppost);
So Easy!
You need the -ExecutionPolicy
parameter:
Powershell.exe -executionpolicy remotesigned -File C:\Users\SE\Desktop\ps.ps1
Otherwise PowerShell considers the arguments a line to execute and while Set-ExecutionPolicy
is a cmdlet, it has no -File
parameter.
You could also just compile the following program and run it on your machine.
#include <gtk/gtk.h>
#include <glib/gprintf.h>
int main(int argc, char *argv[])
{
/* Initialize GTK */
gtk_init (&argc, &argv);
g_printf("%d.%d.%d\n", gtk_major_version, gtk_minor_version, gtk_micro_version);
return(0);
}
compile with ( assuming above source file is named version.c):
gcc version.c -o version `pkg-config --cflags --libs gtk+-2.0`
When you run this you will get some output. On my old embedded device I get the following:
[root@n00E04B3730DF n2]# ./version
2.10.4
[root@n00E04B3730DF n2]#
For Android studio v2.1
Follow these easy steps from images.
This should work :
curl -i -H "Accept: application/json" 'server:5050/a/c/getName{"param0":"pradeep"}'
use option -i instead of x.
Do the build job on Jenkins first without Sonar configured. Then add Sonar, and run a build job again. Should fix the problem
Search your code for unsafe
blocks or statements. These are only valid is compiled with /unsafe
.
You state that you want to encrypt/decrypt a password. I'm not sure exactly of what your specific use case is but, generally, passwords are not stored in a form where they can be decrypted. General practice is to salt the password and use suitably powerful one-way hash (such as PBKDF2).
Take a look at the following link for more information.
You're reading the entire file into memory (line = u.readlines()
) which will fail of course if the file is too large (and you say that some are up to 20 GB), so that's your problem right there.
Better iterate over each line:
for current_line in u:
do_something_with(current_line)
is the recommended approach.
Later in your script, you're doing some very strange things like first counting all the items in a list, then constructing a for
loop over the range of that count. Why not iterate over the list directly? What is the purpose of your script? I have the impression that this could be done much easier.
This is one of the advantages of high-level languages like Python (as opposed to C where you do have to do these housekeeping tasks yourself): Allow Python to handle iteration for you, and only collect in memory what you actually need to have in memory at any given time.
Also, as it seems that you're processing TSV files (tabulator-separated values), you should take a look at the csv
module which will handle all the splitting, removing of \n
s etc. for you.
try this:
puts 'one TWO three foUR'.split.map(&:capitalize).join(' ')
#=> One Two Three Four
or
puts 'one TWO three foUR'.split.map(&:capitalize)*' '
No need to complicate things. With Bootstrap 4, you can simply align items horizontally inside a column using the margin auto class my-auto
<div class="col-md-6 my-auto">
<h3>Lorem ipsum.</h3>
</div>
An addition to the current marked answer:
Place the addhandler inside the following scope, like so:
<IfModule mod_rewrite.c>
AddHandler application/x-httpd-php71 .php
RewriteEngine On
....
</IfModule>
You can do it by using simple one line JavaScript code and also be careful that if JavaScript is turned off it will not work. The below code will do it's job if JavaScript is turned off.
Turn off JavaScript and run the code on you own file to know it's full function.(If you turn off JavaScript here, the below Code Snippet will not work)

Yes, this is an old post. Regardless, someone may find it useful. Here is another way to send parameters to event handlers.
//click handler
function add_event(event, paramA, paramB)
{
//do something with your parameters
alert(paramA ? 'paramA:' + paramA : '' + paramB ? ' paramB:' + paramB : '');
}
//bind handler to click event
$('.leadtoscore').click(add_event);
...
//once you've processed some data and know your parameters, trigger a click event.
//In this case, we will send 'myfirst' and 'mysecond' as parameters
$('.leadtoscore').trigger('click', {'myfirst', 'mysecond'});
//or use variables
var a = 'first',
b = 'second';
$('.leadtoscore').trigger('click', {a, b});
$('.leadtoscore').trigger('click', {a});
This issue occurs if your module is configured with Annotation processor and other module is not.Set the same configuration for all the modules as it wold be cyclic dependency.
Yes. Recent versions of IE (IE8 or above) let you adjust that. Here's how:
That should open the Developer Tools window. That window has two menu items that are of interest:

I haven't done time test with this but it was fun to try. Basically convert two columns to one column of tuples. Now convert that to a dataframe, do 'value_counts()' which finds the unique elements and counts them. Fiddle with zip again and put the columns in order you want. You can probably make the steps more elegant but working with tuples seems more natural to me for this problem
b = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})
b['count'] = pd.Series(zip(*[b.A,b.B]))
df = pd.DataFrame(b['count'].value_counts().reset_index())
df['A'], df['B'] = zip(*df['index'])
df = df.drop(columns='index')[['A','B','count']]
I made custom messagebox using jquery UI
component. Here is demo http://jsfiddle.net/eraj2587/Pm5Fr/14/
You have to pass just the parameters like caption name, message, button's text. You can specify trigger function on any button click. This will helpful for you.
You can do this setting up an event listener for the 'invalid' across all the inputs of the same type, or just one, depending on what you need, and then setting up the proper message.
[].forEach.call( document.querySelectorAll('[type="email"]'), function(emailElement) {
emailElement.addEventListener('invalid', function() {
var message = this.value + 'is not a valid email address';
emailElement.setCustomValidity(message)
}, false);
emailElement.addEventListener('input', function() {
try{emailElement.setCustomValidity('')}catch(e){}
}, false);
});
The second piece of the script, the validity message will be reset, since otherwise won't be possible to submit the form: for example this prevent the message to be triggered even when the email address has been corrected.
Also you don't have to set up the input field as required, since the 'invalid' will be triggered once you start typing in the input.
Here is a fiddle for that: http://jsfiddle.net/napy84/U4pB7/2/ Hope that helps!
This is a nice tutorial:

The functions have different purposes. vector::insert
allows you to insert an object at a specified position in the vector
, whereas vector::push_back
will just stick the object on the end. See the following example:
using namespace std;
vector<int> v = {1, 3, 4};
v.insert(next(begin(v)), 2);
v.push_back(5);
// v now contains {1, 2, 3, 4, 5}
You can use insert
to perform the same job as push_back
with v.insert(v.end(), value)
.
Even if you have indexes on some columns that are used in some queries, the fact that your 'ad-hoc' query causes a table scan shows that you don't have sufficient indexes to allow this query to complete efficiently.
For date ranges in particular it is difficult to add good indexes.
Just looking at your query, the db has to sort all the records by the selected column to be able to return the first n records.
Does the db also do a full table scan without the order by clause? Does the table have a primary key - without a PK, the db will have to work harder to perform the sort?
You need to use Iterator
and call remove()
on iterator
instead of using for
loop.
For those starting with an existing IDEA installation (IDEA 15 in my case) to which they're adding the Android SDK (and not starting formally speaking with Android Studio), ...
Download (just) the SDK to your filesystem (somewhere convenient to you; it doesn't matter where).
When creating your first project and you get to the Project SDK: bit (or adding the Android SDK ahead of time as you wish), navigate (New) to the root of what you exploded into the filesystem as suggested by some of the other answers here.
At that point you'll get a tiny dialog to confirm with:
Java SDK: 1.7 (e.g.)
Build target: Android 6.0 (e.g.)
You can click OK whereupon you'll see what you did as an option in the Project SDK: drop-down, e.g.:
Android API 23 Platform (java version "1.7.0_67")
best and easiest way to do this
public int getDays(String begin) throws ParseException {
long MILLIS_PER_DAY = 24 * 60 * 60 * 1000;
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy", Locale.ENGLISH);
long begin = dateFormat.parse(begin).getTime();
long end = new Date().getTime(); // 2nd date want to compare
long diff = (end - begin) / (MILLIS_PER_DAY);
return (int) diff;
}
Request.RawUrl
Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.
The following res:
(resource) references need to point to your model.
<add name="Entities" connectionString="metadata=
res://*/Models.WraithNath.co.uk.csdl|
res://*/Models.WraithNath.co.uk.ssdl|
res://*/Models.WraithNath.co.uk.msl;
Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).
It also may help to specify the assembly rather than using "//*/".
Worst case, you can check everything (a bit slower but should always find the resource) by using
<add name="Entities" connectionString="metadata=
res://*/;provider= <!-- ... -->
<a href="delete.php?id=22" onclick = "if (! confirm('Continue?')) { return false; }">Confirm OK, then goto URL (uses onclick())</a>
You can write like that. This is for whenever you change context path you don't need to modify your jsp file.
<link rel="stylesheet" href="${pageContext.request.contextPath}/css/styles.css" />
I think what you have missed here is this:
https://maven.apache.org/settings.html#Servers
The repositories for download and deployment are defined by the repositories and distributionManagement elements of the POM. However, certain settings such as username and password should not be distributed along with the pom.xml. This type of information should exist on the build server in the settings.xml.
This is the prefered way of using custom repos. So probably what is happening is that the url of this repo is in settings.xml of the build server.
Once you get hold of the url and credentials, you can put them in your machine here: ~/.m2/settings.xml
like this:
<settings ...>
.
.
.
<servers>
<server>
<id>internal-repository-group</id>
<username>YOUR-USERNAME-HERE</username>
<password>YOUR-PASSWORD-HERE</password>
</server>
</servers>
</settings>
EDIT:
You then need to refer this repository into project POM. The id internal-repository-group can be used in every project. You can setup multiple repos and credentials setting using different IDs in settings xml.
The advantage of this approach is that project can be shared without worrying about the credentials and don't have to mention the credentials in every project.
Following is a sample pom of a project using "internal-repository-group"
<repositories>
<repository>
<id>internal-repository-group</id>
<name>repo-name</name>
<url>http://project.com/yourrepourl/</url>
<layout>default</layout>
<releases>

Encountering the same problem (create InnoDB table) this is what finally worked for me:
DROP DATABASE `having_issues`;
I checked on a file basis, permissions, tried to REPAIR and FLUSH but nothing worked.
So if this is an option, move all working tables to another DATABASE, drop the old one (you might have to manually remove any files from the database folder before the drop to work), rename the new one, and you 'should' be back on your way. Apparently, whatever gets 'cached' using InnoDB is dropped along with the original database.
Here's a dplyr
option:
library(dplyr)
# across all columns:
df %>% filter_all(any_vars(. %in% c('M017', 'M018')))
# or in only select columns:
df %>% filter_at(vars(col1, col2), any_vars(. %in% c('M017', 'M018')))
In 2017 with django 1.11.5 and python 3.6 (from the comment this also works with Python 2.7):
import django
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
django.setup()
The .py
in which you put this code should be in mysite
(the parent one)
You'll want to use a udf as below
from pyspark.sql.types import IntegerType
from pyspark.sql.functions import udf
def func(fruit1, fruit2):
if fruit1 == None or fruit2 == None:
return 3
if fruit1 == fruit2:
return 1
return 0
func_udf = udf(func, IntegerType())
df = df.withColumn('new_column',func_udf(df['fruit1'], df['fruit2']))
Typically, you'd use the NODE_ENV
variable to take special actions when you develop, test and debug your code. For example to produce detailed logging and debug output which you don't want in production. Express itself behaves differently depending on whether NODE_ENV
is set to production
or not. You can see this if you put these lines in an Express app, and then make a HTTP GET request to /error
:
app.get('/error', function(req, res) {
if ('production' !== app.get('env')) {
console.log("Forcing an error!");
}
throw new Error('TestError');
});
app.use(function (req, res, next) {
res.status(501).send("Error!")
})
Note that the latter app.use()
must be last, after all other method handlers!
If you set NODE_ENV
to production
before you start your server, and then send a GET /error
request to it, you should not see the text Forcing an error!
in the console, and the response should not contain a stack trace in the HTML body (which origins from Express).
If, instead, you set NODE_ENV
to something else before starting your server, the opposite should happen.
In Linux, set the environment variable NODE_ENV like this:
export NODE_ENV='value'
If json object key/name contains dot......! like
var myJson = {"my.name":"vikas","my.age":27}
Than you can access like
myJson["my.name"]
myJson["my.age"]
Your web app can now take a 'native' screenshot of the client's entire desktop using getUserMedia()
:
Have a look at this example:
https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/
The client will have to be using chrome (for now) and will need to enable screen capture support under chrome://flags.
The Reason is that your previous build is still running in the background. I solve this problem by following these steps:
queryParams
queryParams
is another input of routerLink
where they can be passed like
<a [routerLink]="['../']" [queryParams]="{prop: 'xxx'}">Somewhere</a>
fragment
<a [routerLink]="['../']" [queryParams]="{prop: 'xxx'}" [fragment]="yyy">Somewhere</a>
routerLinkActiveOptions
To also get routes active class set on parent routes:
[routerLinkActiveOptions]="{ exact: false }"
To pass query parameters to this.router.navigate(...)
use
let navigationExtras: NavigationExtras = {
queryParams: { 'session_id': sessionId },
fragment: 'anchor'
};
// Navigate to the login page with extras
this.router.navigate(['/login'], navigationExtras);
See also https://angular.io/guide/router#query-parameters-and-fragments
Not very simple but:
a = [1,1,1,2,2,3]
b = a.group_by {|n| n}.each {|k,v| v.pop [1,3].count(k)}.values.flatten
=> [1, 1, 2, 2]
Also handles the case for multiples in the 'subtrahend':
a = [1,1,1,2,2,3]
b = a.group_by {|n| n}.each {|k,v| v.pop [1,1,3].count(k)}.values.flatten
=> [1, 2, 2]
EDIT: this is more an enhancement combining Norm212 and my answer to make a "functional" solution.
b = [1,1,3].each.with_object( a ) { |del| a.delete_at( a.index( del ) ) }
Put it in a lambda if needed:
subtract = lambda do |minuend, subtrahend|
subtrahend.each.with_object( minuend ) { |del| minuend.delete_at( minuend.index( del ) ) }
end
then:
subtract.call a, [1,1,3]
Supose you have the following scenario:
* 1bd2200 (HEAD, master) another commit
* d258546 bad commit
* 0f1efa9 3rd commit
* bd8aa13 2nd commit
* 34c4f95 1st commit
Where you want to remove d258546 i.e. "bad commit".
You shall try an interactive rebase to remove it: git rebase -i 34c4f95
then your default editor will pop with something like this:
pick bd8aa13 2nd commit
pick 0f1efa9 3rd commit
pick d258546 bad commit
pick 1bd2200 another commit
# Rebase 34c4f95..1bd2200 onto 34c4f95
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out
just remove the line with the commit you want to strip and save+exit the editor:
pick bd8aa13 2nd commit
pick 0f1efa9 3rd commit
pick 1bd2200 another commit
...
git will proceed to remove this commit from your history leaving something like this (mind the hash change in the commits descendant from the removed commit):
* 34fa994 (HEAD, master) another commit
* 0f1efa9 3rd commit
* bd8aa13 2nd commit
* 34c4f95 1st commit
Now, since I suppose that you already pushed the bad commit to gitlab, you'll need to repush your graph to the repository (but with the -f
option to prevent it from being rejected due to a non fastforwardeable history i.e. git push -f <your remote> <your branch>
)
Please be extra careful and make sure that none coworker is already using the history containing the "bad commit" in their branches.
Alternative option:
Instead of rewrite the history, you may simply create a new commit which negates the changes introduced by your bad commit, to do this just type git revert <your bad commit hash>
. This option is maybe not as clean, but is far more safe (in case you are not fully aware of what are you doing with an interactive rebase).
You need to provide a selector with higher specificity than the one in Main.css
. With that selector, set the values of the properties you want to their default, e.g.
body .c1 {
height: auto;
}
There is no "default" value that will work for all properties, you need to look up what the default is for each one and use that.
Pandas timestamp differences returns a datetime.timedelta object. This can easily be converted into hours by using the *as_type* method, like so
import pandas
df = pandas.DataFrame(columns=['to','fr','ans'])
df.to = [pandas.Timestamp('2014-01-24 13:03:12.050000'), pandas.Timestamp('2014-01-27 11:57:18.240000'), pandas.Timestamp('2014-01-23 10:07:47.660000')]
df.fr = [pandas.Timestamp('2014-01-26 23:41:21.870000'), pandas.Timestamp('2014-01-27 15:38:22.540000'), pandas.Timestamp('2014-01-23 18:50:41.420000')]
(df.fr-df.to).astype('timedelta64[h]')
to yield,
0 58
1 3
2 8
dtype: float64

From docs and example it is not clear that classpath manipulation is not allowed.
<configuration>

But see Java docs (also https://www.cis.upenn.edu/~bcpierce/courses/629/jdkdocs/tooldocs/solaris/javac.html)
-classpath path Specifies the path javac uses to look up classes needed to run javac or being referenced by other classes you are compiling. Overrides the default or the CLASSPATH environment variable if it is set.
Maybe it is possible to get current classpath and extend it,

As already stated, you can use sigaction
to trap ctrl-c, or select
to trap any standard input.
Note however that with the latter method you also need to set the TTY so that it's in character-at-a-time rather than line-at-a-time mode. The latter is the default - if you type in a line of text it doesn't get sent to the running program's stdin until you press enter.
You'd need to use the tcsetattr()
function to turn off ICANON mode, and probably also disable ECHO too. From memory, you also have to set the terminal back into ICANON mode when the program exits!
Just for completeness, here's some code I've just knocked up (nb: no error checking!) which sets up a Unix TTY and emulates the DOS <conio.h>

/* take two copies - one for now, one for later */

atexit(reset_terminal_mode);
cfmakeraw(&new_termios);

This is whole story how date problem was and how Big DBMSs handled these problems.
During the period between 1 A.D. and today, the Western world has actually used two main calendars: the Julian calendar of Julius Caesar and the Gregorian calendar of Pope Gregory XIII. The two calendars differ with respect to only one rule: the rule for deciding what a leap year is. In the Julian calendar, all years divisible by four are leap years. In the Gregorian calendar, all years divisible by four are leap years, except that years divisible by 100 (but not divisible by 400) are not leap years. Thus, the years 1700, 1800, and 1900 are leap years in the Julian calendar but not in the Gregorian calendar, while the years 1600 and 2000 are leap years in both calendars.
When Pope Gregory XIII introduced his calendar in 1582, he also directed that the days between October 4, 1582, and October 15, 1582, should be skipped—that is, he said that the day after October 4 should be October 15. Many countries delayed changing over, though. England and her colonies didn't switch from Julian to Gregorian reckoning until 1752, so for them, the skipped dates were between September 4 and September 14, 1752. Other countries switched at other times, but 1582 and 1752 are the relevant dates for the DBMSs that we're discussing.
Thus, two problems arise with date arithmetic when one goes back many years. The first is, should leap years before the switch be calculated according to the Julian or the Gregorian rules? The second problem is, when and how should the skipped days be handled?
This is how the Big DBMSs handle these questions:
- Pretend there was no switch. This is what the SQL Standard seems to require, although the standard document is unclear: It just says that dates are "constrained by the natural rules for dates using the Gregorian calendar"—whatever "natural rules" are. This is the option that DB2 chose. When there is a pretence that a single calendar's rules have always applied even to times when nobody heard of the calendar, the technical term is that a "proleptic" calendar is in force. So, for example, we could say that DB2 follows a proleptic Gregorian calendar.
- Avoid the problem entirely. Microsoft and Sybase set their minimum date values at January 1, 1753, safely past the time that America switched calendars. This is defendable, but from time to time complaints surface that these two DBMSs lack a useful functionality that the other DBMSs have and that the SQL Standard requires.
- Pick 1582. This is what Oracle did. An Oracle user would find that the date-arithmetic expression October 15 1582 minus October 4 1582 yields a value of 1 day (because October 5–14 don't exist) and that the date February 29 1300 is valid (because the Julian leap-year rule applies). Why did Oracle go to extra trouble when the SQL Standard doesn't seem to require it? The answer is that users might require it. Historians and astronomers use this hybrid system instead of a proleptic Gregorian calendar. (This is also the default option that Sun picked when implementing the GregorianCalendar class for Java—despite the name, GregorianCalendar is a hybrid calendar.)
I would highly recommend reading Apple's guides, and viewing the WWDC resources listed here: Internationalization and Localization Topics
To specifically answer your question, when you add a new language to your project, you get an opportunity to choose what InfoPlist files to include (if you have multiple targets, you'll have multiple Info plist files). All you need to do to get the following screen is hit the + under Localizations and choose a new language to add support for.
Once you've added, it will create the necessary string files in the appropriate lproj directories for the given language.
--EDIT--
Just to be clear, iOS will swap out the string for your Plist file based upon the user's currently selected language using the plist entry's key as the key in the localized strings file.

Be advised that if you're using nodejs there's (at the time of writing) a dependency on libssl 1.0.* - so installing an alternative SSL library will break your nodejs installation.
An alternative solution to installing a different SSL library is that posted in this answer here: https://stackoverflow.com/a/59927568/13564342 to instead install libcurl4-gnutls-dev
sudo apt install libcurl4-gnutls-dev
ComboBox.SelectionBoxItem.ToString()
I don't know much about git on Windows, but...
Appears to me that git is converting the return format to match that of the running platform (Windows). CRLF is the default return format in Windows, while LF is the default return format for most other OSes.
Chances are, the return format will be adjusted properly when the code is moved to another system. I also reckon git is smart enough to keep binary files intact rather than trying to convert LFs to CRLFs in, say, JPEGs.
In summary, you probably don't need to fret too much over this conversion. However, if you go to archive your project as a tarball, fellow coders would probably appreciate having LF line terminators rather than CRLF. Depending on how much you care (and depending on you not using Notepad), you might want to set git to use LF returns if you can :)
Appendix: CR is ASCII code 13, LF is ASCII code 10. Thus, CRLF is two bytes, while LF is one.
If the request body is empty, then it simply means that it's already been consumed beforehand. For example, by a request.getParameter()

Quick comparison with "real" speed test service showed small difference of 0.12 Mbps when using big picture.
To ensure the integrity of the test, you can run the code with Chrome dev tool throttling enabled and then see if the result matches the limitation. (credit goes to user284130 :))
Important things to keep in mind:
The image being used should be properly optimized and compressed. If it isn't, then default compression on connections by the web server might show speed bigger than it actually is. Another option is using uncompressible file format, e.g. jpg. (thanks Rauli Rajande for pointing this out and Fluxine for reminding me)
The cache buster mechanism described above might not work with some CDN servers, which can be configured to ignore query string parameters, hence better setting cache control headers on the image itself. (thanks orcaman for pointing this out))
This works if your Android device is rooted by any means (not sure if it works for non-rooted).
adb shell
- access the shellsu
- become the superuser.You can now read all files in all directories.
After getting the help from @Blender, @ekhumoro and @Dan, I understand the Linux and Python more than before. Thank you. I got the an idea by @ekhumoro, it is I didn't install PyQt5 correctly. So I delete PyQt5 folder and download again. And redo everything from very start.
After redoing, I got the error as my last update at my question. So, when I search at stack, I got the following solution from here
sudo ln -s /usr/include/python2.7 /usr/local/include/python2.7
And then, I did "sudo make" and "sudo make install" step by step. After "sudo make install", I got the following error. But I ignored it and I created a simple design with qt designer. And I converted it into python file by pyuic5. Everything are going well.
install -m 755 -p /home/thura/PyQt/pyuic5 /usr/bin/
strip /usr/bin/pyuic5
strip:/usr/bin/pyuic5: File format not recognized

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)
I've tested this on Twenty Fifteen and it's working, so it should be working for you.
In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:
<div id="ajax-posts" class="row">
<?php
$postsPerPage = 3;
$args = array(
'post_type' => 'post',
'posts_per_page' => $postsPerPage,
'cat' => 8
);
$loop = new WP_Query($args);
while ($loop->have_posts()) : $loop->the_post();
?>
<div class="small-12 large-4 columns">
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>
</div>
<?php
endwhile;
wp_reset_postdata();
?>
</div>
<div id="more_posts">Load More</div>
This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with
$cat_id = get_query_var('cat');
This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like
<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>
And pull the category with
var cat = $('#more_posts').data('category');
But for now, you can leave this out.
Next in functions.php I added
wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
'ajaxurl' => admin_url( 'admin-ajax.php' ),
'noposts' => __('No older posts found', 'twentyfifteen'),
));
Right after the existing wp_localize_script
. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.
At the end of the functions.php file I added the function that will load your posts:
function more_post_ajax(){
$ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
$page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;
header("Content-Type: text/html");
$args = array(
'suppress_filters' => true,
'post_type' => 'post',
'posts_per_page' => $ppp,
'cat' => 8,
'paged' => $page,
);
$loop = new WP_Query($args);
$out = '';
if ($loop -> have_posts()) : while ($loop -> have_posts()) : $loop -> the_post();
$out .= '<div class="small-12 large-4 columns">
<h1>'.get_the_title().'</h1>
<p>'.get_the_content().'</p>
</div>';
endwhile;
endif;
wp_reset_postdata();
die($out);
}
add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');
Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.
If you've added your category in the loader, you'd add:
$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';
And instead of 8, you'd put $cat
. This will be in the $_POST
array, and you'll be able to use it in ajax.
Last part is the ajax itself. In functions.js I put inside the $(document).ready();
enviroment
var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;
function load_posts(){
pageNumber++;
var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
$.ajax({
type: "POST",
dataType: "html",
url: ajax_posts.ajaxurl,
data: str,
success: function(data){
var $data = $(data);
if($data.length){
$("#ajax-posts").append($data);
$("#more_posts").attr("disabled",false);
} else{
$("#more_posts").attr("disabled",true);
}
},
error : function(jqXHR, textStatus, errorThrown) {
$loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
}
});
return false;
}
$("#more_posts").on("click",function(){ // When btn is pressed.
$("#more_posts").attr("disabled",true); // Disable the button, temp.
load_posts();
});
Saved it, tested it, and it works :)
Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD
UPDATE
For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;
) you can try with
$(window).on('scroll', function () {
if ($(window).scrollTop() + $(window).height() >= $(document).height() - 100) {
load_posts();
}
});
This should run the load_posts()
function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer
$(window).on('scroll', function(){
if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
load_posts();
}
}
});
Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100
or $('footer').offset().top
for some reason. If that should happen, just increase the number where the scroll goes to.
You can easily check it by putting console.log
s in your code and see in the inspector what they throw out
$(window).on('scroll', function () {
console.log($(window).scrollTop() + $(window).height());
console.log($(document).height() - 100);
if ($(window).scrollTop() + $(window).height() >= $(document).height() - 100) {
load_posts();
}
});
And just adjust accordingly ;)
Hope this helps :) If you have any questions just ask.
If you want to call JavaScript function in C#, this will help you:
public string functionname(arg)
{
if (condition)
{
Page page = HttpContext.Current.CurrentHandler as Page;
page.ClientScript.RegisterStartupScript(
typeof(Page),
"Test",
"<script type='text/javascript'>functionname1(" + arg1 + ",'" + arg2 + "');</script>");
}
}
If you seek a key that is equivalent to a directory then you might want this approach
session = boto3.session.Session()
resource = session.resource("s3")
bucket = resource.Bucket('mybucket')
key = 'dir-like-or-file-like-key'
objects = [o for o in bucket.objects.filter(Prefix=key).limit(1)]
has_key = len(objects) > 0
This works for a parent key or a key that equates to file or a key that does not exist. I tried the favored approach above and failed on parent keys.
Working with AngularJS the BASE tag broke $cookieStore silently and it took me a while to figure out why my app couldn't write cookies anymore. Be warned...
var res = exitDictionary
.Select(p => p.Value).Cast<Dictionary<string, object>>()
.SelectMany(d => d)
.Where(p => p.Key == "fieldname1")
.Select(p => p.Value).Cast<List<Dictionary<string,string>>>()
.SelectMany(l => l)
.SelectMany(d=> d)
.Where(p => p.Key == "valueTitle")
.Select(p => p.Value)
.ToList();
This also works, and easy to understand.
//for closeing the popover when user click outside it will close all popover
var hidePopover = function(element) {
var elementScope = angular.element($(element).siblings('.popover')).scope().$parent;
elementScope.isOpen = false;
elementScope.$apply();
//Remove the popover element from the DOM
$(element).siblings('.popover').remove();
};
$(document).ready(function(){
$('body').on('click', function (e) {
$("a").each(function () {
//Only do this for all popovers other than the current one that cause this event
if (!($(this).is(e.target) || $(this).has(e.target).length > 0)
&& $(this).siblings('.popover').length !== 0 && $(this).siblings('.popover').has(e.target).length === 0)
{
hidePopover(this);
}
});
});
});
You can also get an updated version of the Eclipse's ADT plugin (based on an unreleased 24.2.0 version) that I managed to patch and compile at https://github.com/khaledev/ADT.
app.use(path, middleware) is used to call middleware function that needs to be called before the route is hit for the corresponding path. Multiple middleware functions can be invoked via an app.use.
app.use(‘/fetch’, enforceAuthentication) -> enforceAuthentication middleware fn will be called when a request starting with ‘/fetch’ is received. It can be /fetch/users, /fetch/ids/{id}, etc
Some middleware functions might have to be called irrespective of the request. For such cases, a path is not specified, and since the the path defaults to / and every request starts with /, this middleware function will be called for all requests.
app.use(() => { // Initialize a common service })
next() fn needs to be called within each middleware function when multiple middleware functions are passed to app.use, else the next middleware function won’t be called.
reference : http://expressjs.com/en/api.html#app.use
Note: The documentation says we can bypass middleware functions following the current one by calling next('route') within the current middleware function, but this technique didn't work for me within app.use but did work with app.METHOD like below. So, fn1 and fn2 were called but not fn3.
app.get('/fetch', function fn1(req, res, next) {
console.log("First middleware function called");
next();
},
function fn2(req, res, next) {
console.log("Second middleware function called");
next("route");
},
function fn3(req, res, next) {
console.log("Third middleware function will not be called");
next();
})
Space characters may only be encoded as "+" in one context: application/x-www-form-urlencoded key-value pairs.
The RFC-1866 (HTML 2.0 specification), paragraph 8.2.1. subparagraph 1. says: "The form field names and values are escaped: space characters are replaced by `+', and then reserved characters are escaped").
Here is an example of such a string in URL where RFC-1866 allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses (in other cases, spaces should be encoded to %20). This way of encoding form data is also given in later HTML specifications, for example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.
But, because it's hard to always correctly determine the context, it's the best practice to never encode spaces as "+". It's better to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3. Here is a code example that illustrates what should be encoded. It is given in Delphi (pascal) programming language, but it is very easy to understand how it works for any programmer regardless of the language possessed:
(* percent-encode all unreserved characters as defined in RFC-3986, p.2.3 *)
function UrlEncodeRfcA(const S: AnsiString): AnsiString;
const
HexCharArrA: array [0..15] of AnsiChar = '0123456789ABCDEF';
var
I: Integer;
c: AnsiChar;
begin
// percent-encoding, see RFC-3986, p. 2.1
Result := S;
for I := Length(S) downto 1 do
begin
c := S[I];
case c of
'A' .. 'Z', 'a' .. 'z', // alpha
'0' .. '9', // digit
'-', '.', '_', '~':; // rest of unreserved characters as defined in the RFC-3986, p.2.3
else
begin
Result[I] := '%';
Insert('00', Result, I + 1);
Result[I + 1] := HexCharArrA[(Byte(C) shr 4) and $F)];
Result[I + 2] := HexCharArrA[Byte(C) and $F];
end;
end;
end;
end;
function UrlEncodeRfcW(const S: UnicodeString): AnsiString;
begin
Result := UrlEncodeRfcA(Utf8Encode(S));
end;
<form id="myform">
<input type="textbox" id="field"/>

$("#field").keyup(function (event) {
if (event.which === 13) {
document.myform.submit();
}
}
});

With Exuberant ctags, you can create tag files with file information:
ctags --extra=+f -R *
Then, open file from VIM with
:tag filename
You can also use <tab>
to autocomplete file name.
It got simplified with newer version of rxjs .
import {map} from 'rxjs/operators';
import {Observable,of, from } from 'rxjs';
Instead of chaining we need to pipe . For example
Old syntax :
source.map().switchMap().subscribe()
New Syntax:
source.pipe(map(), switchMap()).subscribe()
Note: Some operators have a name change due to name collisions with JavaScript reserved words! These include:
do
-> tap
,
catch
-> catchError
switch
-> switchAll
finally
-> finalize
I am writing this answer partly to help myself as I keep checking docs everytime I need to import an operator . Let me know if something can be done better way.
import { Rx } from 'rxjs/Rx'
;This imports the entire library. Then you don't need to worry about loading each operator . But you need to append Rx. I hope tree-shaking will optimize and pick only needed funcionts( need to verify ) As mentioned in comments , tree-shaking can not help. So this is not optimized way.
public cache = new Rx.BehaviorSubject('');
Or you can import individual operators .
This will Optimize your app to use only those files :
import { _______ } from 'rxjs/_________';
This syntax usually used for main Object like Rx
itself or Observable
etc.,
Keywords which can be imported with this syntax
Observable, Observer, BehaviorSubject, Subject, ReplaySubject
import 'rxjs/add/observable/__________';
Update for Angular 5
With Angular 5, which uses rxjs 5.5.2+
import { empty } from 'rxjs/observable/empty';
import { concat} from 'rxjs/observable/concat';
These are usually accompanied with Observable directly. For example
Observable.from()
Observable.of()
Other such keywords which can be imported using this syntax:
concat, defer, empty, forkJoin, from, fromPromise, if, interval, merge, of,
range, throw, timer, using, zip
import 'rxjs/add/operator/_________';
Update for Angular 5
With Angular 5, which uses rxjs 5.5.2+
import { filter } from 'rxjs/operators/filter';
import { map } from 'rxjs/operators/map';
These usually come in the stream after the Observable is created. Like flatMap
in this code snippet:
Observable.of([1,2,3,4])
.flatMap(arr => Observable.from(arr));
Other such keywords using this syntax:
audit, buffer, catch, combineAll, combineLatest, concat, count, debounce, delay,
distinct, do, every, expand, filter, finally, find , first, groupBy,
ignoreElements, isEmpty, last, let, map, max, merge, mergeMap, min, pluck,
publish, race, reduce, repeat, scan, skip, startWith, switch, switchMap, take,
takeUntil, throttle, timeout, toArray, toPromise, withLatestFrom, zip
FlatMap:
flatMap
is alias to mergeMap
so we need to import mergeMap
to use flatMap
.
Note for /add
imports :
We only need to import once in whole project. So its advised to do it at a single place. If they are included in multiple files, and one of them is deleted, the build will fail for wrong reasons.
Both IP and DNS can be specified with the keytool additional argument -ext SAN=dns:abc.com,ip:1.1.1.1
Example:
keytool -genkeypair -keystore <keystore> -dname "CN=test, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown" -keypass <keypwd> -storepass <storepass> -keyalg RSA -alias unknown -ext SAN=dns:test.abc.com,ip:1.1.1.1
Create a file called "SetFile.bat" that contains the following line with no carriage return at the end of it...
set FileContents=
Then in your batch file do something like this...
@echo off
copy SetFile.bat + %1 $tmp$.bat > nul
call $tmp$.bat
del $tmp$.bat
%1 is the name of your input file and %FileContents% will contain the contents of the input file after the call. This will only work on a one line file though (i.e. a file containing no carriage returns). You could strip out/replace carriage returns from the file before calling the %tmp%.bat if needed.
I prefer to use
<input type='date' id='hasta' value='<?php echo date('Y-m-d');?>'>
that works well
Please check the directory path whether exists or not. This error comes up if the folder doesn't exists from where you are running the command. Probably you have executed a remove command from same path in command line.
The <prev>
-tag might be an XML-tag.
maydenec is correct (in my case...). The file was moved.
I even found this file:
C:\Program Files (x86)\Android\android-sdk\tools\adb_has_moved.txt
Which explained this issue.
Suggestions in this file:
To optimize the EXISTS
, be very literal; something just has to be there, but you don't actually need any data returned from the correlated sub-query. You're just evaluating a Boolean condition.
So:
WHERE EXISTS (SELECT TOP 1 1 FROM Base WHERE bx.BoxID = Base.BoxID AND [Rank] = 2)
Because the correlated sub-query is RBAR
, the first result hit makes the condition true, and it is processed no further.
PHPWord can generate Word documents in docx format. It can also use an existing .docx file as a template - template variables can be added to the document in the format ${varname}
It has an LGPL license and the examples that came with the code worked nicely for me.
Gustavomcls's solution to change com.google.* version to same version worked for me .
I change both dependancies to 9.2.1 in buid.gradle (Module:app)
compile 'com.google.firebase:firebase-ads:9.2.1'
compile 'com.google.android.gms:play-services:9.2.1'
SELECT * FROM NOTES ORDER BY UPPER(title)
Some of the brokerage firms like TDAmeritrade have APIs you can use to get streaming data from their servers:

I tried the answer described here but it doesn´t worked for me. I have the last Android SDK tools ver. 23.0.2 and Android SDK Platform-tools ver. 20
The support library android-support-v4.jar
is causing this conflict, just delete the library under /libs
folder of your project, don´t be scared, the library is already contained in the library appcompat_v7
, clean and build your project, and your project will work like a charm!
If you've copied a disk (vmdk file) from one machine to another and need to change a disk's UUID in the copy, you don't need to change the Machine UUID as has been suggested by another answer.
All you need to do is to assign a new UUID to the disk image:
VBoxManage internalcommands sethduuid your-box-disk2.vmdk
UUID changed to: 5d34479f-5597-4b78-a1fa-94e200d16bbb
and then replace the old UUID with the newly generated one in two places in your *.vbox file
<MediaRegistry>
<HardDisks>
<HardDisk uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}" location="box-disk2.vmdk" format="VMDK" type="Normal"/>
</HardDisks>
and in
<AttachedDevice type="HardDisk" hotpluggable="false" port="0" device="0">
<Image uuid="{5d34479f-5597-4b78-a1fa-94e200d16bbb}"/>
</AttachedDevice>
It worked for me for VirtualBox ver. 5.1.8 running on Mac OS X El Capitan.
You can do it in the following way:
myfxn <- function(var1,var2,var3){
var1*var2*var3
}
lapply(1:3,myfxn,var2=2,var3=100)
and you will get the answer:
[[1]] [1] 200
[[2]] [1] 400
[[3]] [1] 600
I'd do this:
add the dependency as you like in your pom:
<dependency>
<groupId>com.stackoverflow...</groupId>
<artifactId>artifactId...</artifactId>
<version>1.0</version>
</dependency>
run mvn install
it will try to download the jar and fail. On the process, it
will give you the complete command of installing the jar with the error message. Copy that command and run it! easy huh?!
The newest version of the Android emulator can be run with Hyper-V instead of Intel HAXM on the Windows 10 1804:
https://blogs.msdn.microsoft.com/visualstudio/2018/05/08/hyper-v-android-emulator-support/
Short version:
You make one div somewhere on the page and put this code:
<div id="winSize"></div>
<script>
var WindowsSize=function(){
var h=$(window).height(),
w=$(window).width();
$("#winSize").html("<p>Width: "+w+"<br>Height: "+h+"</p>");
};
$(document).ready(WindowsSize);
$(window).resize(WindowsSize);
</script>
Here is a snippet:
var WindowsSize=function(){_x000D_
var h=$(window).height(),_x000D_
w=$(window).width();_x000D_
$("#winSize").html("<p>Width: "+w+"<br>Height:"+h+"</p>");_x000D_

Of course, adapt it to fit your needs! ;)
I think if you are looking for fullscreen only, no need to set geometry or maxsize etc.
You just need to do this:
-If you are working on ubuntu:
root=tk.Tk()
root.attributes('-zoomed', True)
-and if you are working on windows:
root.state('zoomed')
Now for toggling between fullscreen, for minimising it to taskbar you can use:
Root.iconify()
I don't think you need a case statement. You just need to update your where clause and make sure you have correct parentheses to group the clauses.
SELECT Sum(CAMount) as PaymentAmount
from TableOrderPayment
where (CStatus = 'Active' AND CPaymentType = 'Cash')
OR (CStatus = 'Active' and CPaymentType = 'Check' and CDate<=SYSDATETIME())
The answers posted before mine assume that CDate<=SYSDATETIME() is also appropriate for Cash payment type as well. I think I split mine out so it only looks for that clause for check payments.
You have to add the following dependency to your build:
<dependency>
<groupId>org.openrdf.sesame</groupId>
<artifactId>sesame-rio-api</artifactId>
<version>2.7.2</version>
</dependency>
Furthermore i would suggest to take a deep look into the documentation about how to use the lib.
The first solution I can think of, is to use ViewBag to store the values that must be rendered.
Onestly I never tried if this work from a partial view, but it should imo.
This should accomplish what you want to do. I just tested it on a sheet of mine; let me know if this doesn't work. LTrim is if you only have leading spaces; the Trim function can be used as well as it takes care of leading and trailing spaces. Replace the range of cells in the area I have as "A1:C50" and also make sure to change "Sheet1" to the name of the sheet you're working on.
Dim cell As Range, areaToTrim As Range

I got the solution to send the JSON data by POST request through jquery ajax. I used below code
var data = new Object();
data.p_clientId = 4;
data = JSON.stringify(data);
$.ajax({
method: "POST",
url: "http://192.168.1.141:8090/api/Client_Add",
data: data,
headers: {
'Accept': 'application/json',
'Content-Type': 'text/plain'
}
})
.done(function( msg ) {
alert( "Data Saved: " + msg );
});
});
});
I used 'Content-Type': 'text/plain'
in header to send the raw json data.
Because if we use Content-Type: 'application/json'
the request methods converted to OPTION, but using Content-Type: 'test/plain'
the method does not get converted and remain as POST.
Hopefully this will help some one.
I realize this was asked several months ago, but I have an addition to samccone's answer which is more succinct but I don't have the rep to add as a comment!
Instead of:
(123456789).toString(10).split("").map(function(t){return parseInt(t)})
Consider:
(123456789).toString(10).split("").map(Number)
Here's A generic VBA Array To Range function that writes an array to the sheet in a single 'hit' to the sheet. This is much faster than writing the data into the sheet one cell at a time in loops for the rows and columns... However, there's some housekeeping to do, as you must specify the size of the target range correctly.
This 'housekeeping' looks like a lot of work and it's probably rather slow: but this is 'last mile' code to write to the sheet, and everything is faster than writing to the worksheet. Or at least, so much faster that it's effectively instantaneous, compared with a read or write to the worksheet, even in VBA, and you should do everything you possibly can in code before you hit the sheet.
A major component of this is error-trapping that I used to see turning up everywhere . I hate repetitive coding: I've coded it all here, and - hopefully - you'll never have to write it again.
A VBA 'Array to Range' function
Public Sub ArrayToRange(rngTarget As Excel.Range, InputArray As Variant)
' Write an array to an Excel range in a single 'hit' to the sheet
' InputArray must be a 2-Dimensional structure of the form Variant(Rows, Columns)
' The target range is resized automatically to the dimensions of the array, with
' the top left cell used as the start point.
' This subroutine saves repetitive coding for a common VBA and Excel task.
' If you think you won't need the code that works around common errors (long strings
' and objects in the array, etc) then feel free to comment them out.

You will need the source for ArrayDimensions:
This API declaration is required in the module header:
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
(Destination As Any, _
Source As Any, _
ByVal Length As Long)
...And here's the function itself:
Private Function ArrayDimensions(arr As Variant) As Integer
'-----------------------------------------------------------------
' will return:
' -1 if not an array
' 0 if an un-dimmed array
' 1 or more indicating the number of dimensions of a dimmed array

Also: I would advise you to keep that declaration private. If you must make it a public Sub in another module, insert the Option Private Module
statement in the module header. You really don't want your users calling any function with CopyMemoryoperations and pointer arithmetic.
Happened the same to me. It turns out that
var data = $("#myObject").data();
gives you a non-writable object. I solved it using:
var data = $.extend({}, $("#myObject").data());
And from then on, data
was a standard, writable JS object.

The above answers are good, but in my case, 1st approach that converts the function to be a static didn't work. I was trying to convert exiting code to move into thread function but that code had lots to references to non-static class members already. The second solution of encapsulating into C++ object works, but has 3-level wrappers to run a thread.
I had an alternate solution that uses existing C++ construct - 'friend' function, and it worked perfect for my case. An example of how I used 'friend' (will use the above same example for names showing how it can be converted into a compact form using friend)
class MyThreadClass
{
public:
MyThreadClass() {/* empty */}
virtual ~MyThreadClass() {/* empty */}
bool Init()
{
return (pthread_create(&_thread, NULL, &ThreadEntryFunc, this) == 0);
}
/** Will not return until the internal thread has exited. */
void WaitForThreadToExit()
{
(void) pthread_join(_thread, NULL);
}
private:
//our friend function that runs the thread task
friend void* ThreadEntryFunc(void *);
pthread_t _thread;
};
//friend is defined outside of class and without any qualifiers
void* ThreadEntryFunc(void *obj_param) {
MyThreadClass *thr = ((MyThreadClass *)obj_param);
//access all the members using thr->
return NULL;
}
Ofcourse, we can use boost::thread and avoid all these, but I was trying to modify the C++ code to not use boost (the code was linking against boost just for this purpose)
I was getting this error in Visual Studio Code
while doing ng-build
. Running below command in cmd fixed my issue

This can also be achieved using LINQ fluent syntax:
var list = ctn.Items
.Where(t=> t.DeliverySelection == true && t.Delivery.SentForDelivery == null)
.OrderBy(t => t.Delivery.SubmissionDate)
.Take(5);
Note that each method (Where
, OrderBy
, Take
) that appears in this LINQ statement takes a lambda expression as an argument. Also note that the documentation for Enumerable.Take
begins with:
Returns a specified number of contiguous elements from the start of a sequence.
See ?Control
or the R Language Definition:
> y=0
> while(y <5){ print( y<-y+1) }
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
So do_while
does not exist as a separate construct in R, but you can fake it with:
repeat( { expressions}; if (! end_cond_expr ) {break} )
If you want to see the help page you cannot type ?while
or ?repeat
at the console but rather need to use ?'repeat'
or ?'while'
. All the "control-constructs" including if
are on the same page and all need character quoting after the "?" so the interpreter doesn't see them as incomplete code and give you a continuation "+".
You can always format a date by extracting the parts and combine them using string functions:
var date = new Date();_x000D_
var dateStr =_x000D_
("00" + (date.getMonth() + 1)).slice(-2) + "/" +_x000D_
("00" + date.getDate()).slice(-2) + "/" +_x000D_
date.getFullYear() + " " +_x000D_
("00" + date.getHours()).slice(-2) + ":" +_x000D_
("00" + date.getMinutes()).slice(-2) + ":" +_x000D_
("00" + date.getSeconds()).slice(-2);_x000D_
console.log(dateStr);

I have faced two errors while Build my project on Android Studio:
License for package Android SDK Platform 28 not accepted. (while Build my project in Android Studio 4.1)
exception in thread main java.lang.noclassdeffounderror javax/xml/bind/annotation/xmlschema (while running SDK manager to accept license)
For me, it was a java version problem. I have installed JDK instead of java. TO SOLVE THE ISSUE, I did the following steps.
For Windows:
Step1: Download and install the latest JAVA version from https://www.java.com/en/download/
Step2: Search for "View advanced system settings" in the start menu button (windows icon)
Step3: Click on "Environment Variables"
Step4: under "System variables" click on "New", now set "Variable name: JAVA_HOME
" and "Variable value: C:\Program Files\Java\jre1.8.0_271
" (add latest installed java path here). Then "OK", "OK", and "OK".
Step5: open cmd as an administrator and type the following commands:
cd C:\Users\kevin\AppData\Local\Android\Sdk\tools\bin
(*change username here)
sdkmanager --licenses
Press "y" for all questions.
Step6: Restart your Android Studio again.
DONE.
Let me know if anyone having a problem while following the above steps.
Steps to install curl in windows
Install cURL on Windows
There are 4 steps to follow to get cURL installed on Windows.
Step 1 and Step 2 is to install SSL library. Step 3 is to install cURL. Step 4 is to install a recent certificate
Step One: Install Visual C++ 2008 Redistributables
From https://www.microsoft.com/en-za/download/details.aspx?id=29 For 64bit systems Visual C++ 2008 Redistributables (x64) For 32bit systems Visual C++ 2008 Redistributables (x32)
Step Two: Install Win(32/64) OpenSSL v1.0.0k Light
From http://www.shininglightpro.com/products/Win32OpenSSL.html For 64bit systems Win64 OpenSSL v1.0.0k Light For 32bit systems Win32 OpenSSL v1.0.0k Light
Step Three: Install cURL
Depending on if your system is 32 or 64 bit, download the corresponding** curl.exe.** For example, go to the Win64 - Generic section and download the Win64 binary with SSL support (the one where SSL is not crossed out). Visit http://curl.haxx.se/download.html
Copy curl.exe to C:\Windows\System32
Step Four: Install Recent Certificates
Do not skip this step. Download a recent copy of valid CERT files from https://curl.haxx.se/ca/cacert.pem Copy it to the same folder as you placed curl.exe (C:\Windows\System32) and rename it as curl-ca-bundle.crt
If you have already installed curl
or after doing the above steps, add the directory where it's installed to the windows path:
1 - From the Desktop, right-click My Computer and click Properties.
2 - Click Advanced System Settings .
3 - In the System Properties window click the Environment Variables button.
4 - Select Path and click Edit.
5 - Append ;c:\path to curl directory at the end.
5 - Click OK.
6 - Close and re-open the command prompt
In my case I had to run Netbeans as administrator, that solved the problem for me. I'm using Apache Netbeans IDE 11.0
This is a part from a REST-Service I´ve written recently.
var select = $("#productSelect")
for (var prop in data) {
var option = document.createElement('option');
option.innerHTML = data[prop].ProduktName
option.value = data[prop].ProduktName;
select.append(option)
}
The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.
The environment variables displayed in Jenkins (Manage Jenkins -> System information) are inherited from the system (i.e. inherited environment variables)
If you run env
command in a shell you should see the same environment variables as Jenkins shows.
These variables are either set by the shell/system or by you in ~/.bashrc
, ~/.bash_profile
.
There are also environment variables set by Jenkins when a job executes, but these are not displayed in the System Information.
If you are more comfortable with a GUI, you can use the pgAdmin software.
Refered to the answers given above (I do not have enough reputation to refer separately to individual solutions, hence I do this collectively in this place), I want to supplement them with some important suggestions:
docker-compose you can install from the repository (if you have this package in the repository, if not you can adding to system a repository with this package) or download binary with use curl - totourial on the official website of the project - src: https://docs.docker.com/compose/install /
docker-compose from the repository is in version 1.8.0 (at least at me). This docker-compose version does not support configuration files in version 3. It only has version = <2 support. Inthe official site of the project is a recommendation to use container configuration in version 3 - src: https://docs.docker.com/compose/compose-file / compose-versioning /. From my own experience with work in the docker I recommend using container configurations in version 3 - there are more configuration options to use than in versions <3. If you want to use the configurations configurations in version 3 you have to do update / install docker-compose to the version of at least 1.17 - preferably the latest stable. The official site of the project is toturial how to do this process - src: https://docs.docker.com/compose/install/
when you try to manually remove the old docker-compose binaries, you can have information about the missing file in the default path /usr/local/bin/docker-compose
. At my case, docker-compose was in the default path /usr/bin/docker-compose. In this case, I suggest you use the find tool in your system to find binary file docker-compose - example syntax: sudo find / -name 'docker-compose'
. It helped me. Thanks to this, I removed the old docker-compose version and added the stable to the system - I use the curl tool to download binary file docker-compose, putting it in the right path and giving it the right permissions - all this process has been described in the posts above.

Nope, BeautifulSoup, by itself, does not support XPath expressions.
An alternative library, lxml, does support XPath 1.0. It has a BeautifulSoup compatible mode where it'll try and parse broken HTML the way Soup does. However, the default lxml HTML parser does just as good a job of parsing broken HTML, and I believe is faster.
Once you've parsed your document into an lxml tree, you can use the .xpath()
method to search for elements.
try:
# Python 2
from urllib2 import urlopen
except ImportError:
from urllib.request import urlopen
from lxml import etree
url = "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = urlopen(url)
htmlparser = etree.HTMLParser()
tree = etree.parse(response, htmlparser)
tree.xpath(xpathselector)
There is also a dedicated lxml.html()
module with additional functionality.
Note that in the above example I passed the response
object directly to lxml
, as having the parser read directly from the stream is more efficient than reading the response into a large string first. To do the same with the requests
library, you want to set stream=True
and pass in the response.raw
object after enabling transparent transport decompression:
import lxml.html
import requests
url = "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = requests.get(url, stream=True)
response.raw.decode_content = True
tree = lxml.html.parse(response.raw)
Of possible interest to you is the CSS Selector support; the CSSSelector
class translates CSS statements into XPath expressions, making your search for td.empformbody
that much easier:
from lxml.cssselect import CSSSelector
td_empformbody = CSSSelector('td.empformbody')
for elem in td_empformbody(tree):
# Do something with these table cells.
Coming full circle: BeautifulSoup itself does have very complete CSS selector support:
for cell in soup.select('table#foobar td.empformbody'):
# Do something with these table cells.
Since January 7th, 2019, it is possible: unlimited free private repositories on GitHub!
... But for up to three collaborators per private repository.
Nat Friedman just announced it by twitter:
Today(!) we’re thrilled to announce unlimited free private repos for all GitHub users, and a new simplified Enterprise offering:
"New year, new GitHub: Announcing unlimited free private repos and unified Enterprise offering"
For the first time, developers can use GitHub for their private projects with up to three collaborators per repository for free.
Many developers want to use private repos to apply for a job, work on a side project, or try something out in private before releasing it publicly.
Starting today, those scenarios, and many more, are possible on GitHub at no cost.Public repositories are still free (of course—no changes there) and include unlimited collaborators.
Because most of the answer here didn't work, or only partially worked:
body.modal-open .modal[style]:not([style='display: none;']) {
display: flex !important;
height: 100%;
}
body.modal-open .modal[style]:not([style='display: none;']) .modal-dialog {
margin: auto;
}
You have to use the [style] selector to only apply the style on the modal that is currently active instead of all the modals. .in
would have been great, but it appears to be added only after the transition is complete which is too late and makes for some really bad transitions. Fortunately it appears bootstrap always applies a style attribute on the modal just as it is starting to show so this is a bit hacky, but it works.
The :not([style='display: none;'])
portion is a workaround to bootstrap not correctly removing the style attribute and instead setting the style display to none when you close the dialog.
We can get a list of files inside a folder on the file system using various golang standard library functions.
package main
import (
"fmt"
"io/ioutil"
"log"
"os"
"path/filepath"
)
func main() {
var (
root string
files []string
err error
)
root := "/home/manigandan/golang/samples"
// filepath.Walk
files, err = FilePathWalkDir(root)
if err != nil {
panic(err)
}
// ioutil.ReadDir
files, err = IOReadDir(root)
if err != nil {
panic(err)
}
//os.File.Readdir
files, err = OSReadDir(root)
if err != nil {
panic(err)
}
for _, file := range files {
fmt.Println(file)
}
}
The
path/filepath
package provides a handy way to scan all the files in a directory, it will automatically scan each sub-directories in the directory.
func FilePathWalkDir(root string) ([]string, error) {
var files []string
err := filepath.Walk(root, func(path string, info os.FileInfo, err error) error {
if !info.IsDir() {
files = append(files, path)
}
return nil
})
return files, err
}
ioutil.ReadDir
reads the directory named by dirname and returns a list of directory entries sorted by filename.
func IOReadDir(root string) ([]string, error) {
var files []string
fileInfo, err := ioutil.ReadDir(root)
if err != nil {
return files, err
}
for _, file := range fileInfo {
files = append(files, file.Name())
}
return files, nil
}
Readdir reads the contents of the directory associated with file and returns a slice of up to n FileInfo values, as would be returned by Lstat, in directory order. Subsequent calls on the same file will yield further FileInfos.
func OSReadDir(root string) ([]string, error) {
var files []string
f, err := os.Open(root)
if err != nil {
return files, err
}
fileInfo, err := f.Readdir(-1)
f.Close()
if err != nil {
return files, err
}
for _, file := range fileInfo {
files = append(files, file.Name())
}
return files, nil
}

Changed blak3r his code a bit. In case you have two adapters with the same speed. Sort by MAC, so you always get the same value.
public string GetMacAddress()
{
const int MIN_MAC_ADDR_LENGTH = 12;
string macAddress = string.Empty;
Dictionary<string, long> macPlusSpeed = new Dictionary<string, long>();
try
{
foreach(NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
System.Diagnostics.Debug.WriteLine("Found MAC Address: " + nic.GetPhysicalAddress() + " Type: " + nic.NetworkInterfaceType);
string tempMac = nic.GetPhysicalAddress().ToString();
if(!string.IsNullOrEmpty(tempMac) && tempMac.Length >= MIN_MAC_ADDR_LENGTH)
macPlusSpeed.Add(tempMac, nic.Speed);
}
macAddress = macPlusSpeed.OrderByDescending(row => row.Value).ThenBy(row => row.Key).FirstOrDefault().Key;
}
catch{}
System.Diagnostics.Debug.WriteLine("Fastest MAC address: " + macAddress);
return macAddress;
}
You want the (standard) POSIXt
type from base R that can be had in 'compact form' as a POSIXct
(which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt
(which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)
Quick example:
R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10 # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))
$sec
[1] 11.79
$min
[1] 39
$hour
[1] 18
$mday
[1] 25
$mon
[1] 11
$year
[1] 109
$wday
[1] 5
$yday
[1] 358
$isdst
[1] 0
attr(,"tzone")
[1] "America/Chicago" "CST" "CDT"

As for reading them in, see help(strptime)
As for difference, easy too:
R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")
Time difference of 51.25 weeks

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.
write it like this
p {
padding-bottom: 3cm;
}
or
p {
margin-bottom: 3cm;
}
All three are not the conventions.
Use com.stackoverflow.mypackage
.
The package names do not follow camel casing or underscores or hyphens package naming convention.
Also, Google Java Style Guide specifies exactly the same (i.e. com.stackoverflow.mypackage
) convention:
5.2.1 Package names
Package names are all lowercase, with consecutive words simply concatenated together (no underscores). For example,
com.example.deepspace
, notcom.example.deepSpace
orcom.example.deep_space
.— Google Java Style Guide: 5.2 Rules by identifier type: 5.2.1 Package names.
I do it like this in python 3:
with open('myfile.txt', 'w') as f:
print(mydictionary, file=f)
If you're using (or are happy to use) Apache Commons Collections, you can use CollectionUtils.isEqualCollection which "returns true iff the given Collections contain exactly the same elements with exactly the same cardinalities."
I like this one (taken from jquery-howto.blogspot.co.uk):
// get an array with all querystring values
// example: var valor = getUrlVars()["valor"];
function getUrlVars() {
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
Works great for me.
If one wants to have the conf\logging.properties
read one must (see also here) dump this file into the Servers\Tomcat v7.0 Server at localhost-config\
folder and then add the lines :
-Djava.util.logging.config.file="${workspace_loc}\Servers\Tomcat v7.0 Server at localhost-config\logging.properties" -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
to the VM arguments of the launch configuration one is using.
This may have taken a restart or two (or not) but finally I saw in the console in bright red :
FINE: No TLD files were found in [file:/C:/Dropbox/eclipse_workspaces/javaEE/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/ted2012/WEB-INF/lib/logback-classic-1.0.7.jar]. Consider adding the JAR to the tomcat.util.scan.DefaultJarScanner.jarsToSkip or org.apache.catalina.startup.TldConfig.jarsToSkip property in CATALINA_BASE/conf/catalina.properties file. //etc
I still don't know when exactly this EDIT: from the comment by @Stephan: "The FINE warning appears each time any change is done in the JSP file".FINE
warning appears - does not appear immediately on tomcat launch
Bonus: To make the warning go away add in catalina.properties
:
# Additional JARs (over and above the default JARs listed above) to skip when
# scanning for TLDs. The list must be a comma separated list of JAR file names.
org.apache.catalina.startup.TldConfig.jarsToSkip=logback-classic-1.0.7.jar,\
joda-time-2.1.jar,joda-time-2.1-javadoc.jar,mysql-connector-java-5.1.24-bin.jar,\

I was having trouble converting struct to JSON, sending it as response from Golang, then, later catch the same in JavaScript via Ajax.
Wasted a lot of time, so posting solution here.
In Go:
// web server
type Foo struct {
Number int `json:"number"`
Title string `json:"title"`
}
foo_marshalled, err := json.Marshal(Foo{Number: 1, Title: "test"})
fmt.Fprint(w, string(foo_marshalled)) // write response to ResponseWriter (w)
In JavaScript:
// web call & receive in "data", thru Ajax/ other
var Foo = JSON.parse(data);
console.log("number: " + Foo.number);
console.log("title: " + Foo.title);
