Based on K3N answer, I rewrite code generally for anyone wants
var oc = document.createElement('canvas'), octx = oc.getContext('2d');
oc.width = img.width;
oc.height = img.height;
octx.drawImage(img, 0, 0);
while (oc.width * 0.5 > width) {
oc.width *= 0.5;
oc.height *= 0.5;
octx.drawImage(oc, 0, 0, oc.width, oc.height);
}
oc.width = width;
oc.height = oc.width * img.height / img.width;
octx.drawImage(img, 0, 0, oc.width, oc.height);

I encountered this error while trying to convert Tiff images to Jpeg. For me the issue stemmed from the tiff dimensions being too large. Anything up to around 62000 pixels was fine, anything above this size produced the error.
I know that this question is a little old, but I thought that I would provide an alternative which, in my opinion, might be a little easier. If you're willing to add "temporary" columns to a data set, you can use Excel's Analysis ToolPak?Data Analysis?Regression. The secret to doing a quadratic or a cubic regression analysis is defining the Input X Range:.
If you're doing a simple linear regression, all you need are 2 columns, X & Y. If you're doing a quadratic, you'll need X_1, X_2, & Y where X_1 is the x variable and X_2 is x^2; likewise, if you're doing a cubic, you'll need X_1, X_2, X_3, & Y where X_1 is the x variable, X_2 is x^2 and X_3 is x^3. Notice how the Input X Range is from A1 to B22, spanning 2 columns.
The following image the output of the regression analysis. I've highlighted the common outputs, including the R-Squared values and all the coefficients.
One way to "normalize" the appearance in the different browsers is using your "server-side" to resize the image. An example using a C# controller:
public ActionResult ResizeImage(string imageUrl, int width)
{
WebImage wImage = new WebImage(imageUrl);
wImage = WebImageExtension.Resize(wImage, width);
return File(wImage.GetBytes(), "image/png");
}
where WebImage is a class in System.Web.Helpers.
WebImageExtension is defined below:
using System.IO;
using System.Web.Helpers;
using System.Drawing;
using System.Drawing.Imaging;
using System.Drawing.Drawing2D;
using System.Collections.Generic;
public static class WebImageExtension
{
private static readonly IDictionary<string, ImageFormat> TransparencyFormats =
new Dictionary<string, ImageFormat>(StringComparer.OrdinalIgnoreCase) { { "png", ImageFormat.Png }, { "gif", ImageFormat.Gif } };
public static WebImage Resize(this WebImage image, int width)
{
double aspectRatio = (double)image.Width / image.Height;
var height = Convert.ToInt32(width / aspectRatio);
ImageFormat format;
if (!TransparencyFormats.TryGetValue(image.ImageFormat.ToLower(), out format))
{
return image.Resize(width, height);
}
using (Image resizedImage = new Bitmap(width, height))
{
using (var source = new Bitmap(new MemoryStream(image.GetBytes())))
{
using (Graphics g = Graphics.FromImage(resizedImage))
{
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
g.DrawImage(source, 0, 0, width, height);
}
}
using (var ms = new MemoryStream())
{
resizedImage.Save(ms, format);
return new WebImage(ms.ToArray());
}
}
}
}
note the option InterpolationMode.HighQualityBicubic. This is the method used by Chrome.
Now you need publish in a web page. Lets going use razor:
<img src="@Url.Action("ResizeImage", "Controller", new { urlImage = "<url_image>", width = 35 })" />
And this worked very fine to me!
Ideally will be better to save the image beforehand in diferent widths, using this resize algorithm, to avoid the controller process in every image load.
(Sorry for my poor english, I'm brazilian...)
I just ran a page of side by sides comparisons and unless something has changed recently, I could see no better downsizing (scaling) using canvas vs. simple css. I tested in FF6 Mac OSX 10.7. Still slightly soft vs. the original.
I did however stumble upon something that did make a huge difference and that was using image filters in browsers that support canvas. You can actually manipulate images much like you can in Photoshop with blur, sharpen, saturation, ripple, grayscale, etc.
I then found an awesome jQuery plug-in which makes application of these filters a snap: http://codecanyon.net/item/jsmanipulate-jquery-image-manipulation-plugin/428234
I simply apply the sharpen filter right after resizing the image which should give you the desired effect. I didn't even have to use a canvas element.
I use the following method to calculate the desired image size:
using System.Drawing;
public static Size ResizeKeepAspect(this Size src, int maxWidth, int maxHeight, bool enlarge = false)
{
maxWidth = enlarge ? maxWidth : Math.Min(maxWidth, src.Width);
maxHeight = enlarge ? maxHeight : Math.Min(maxHeight, src.Height);
decimal rnd = Math.Min(maxWidth / (decimal)src.Width, maxHeight / (decimal)src.Height);
return new Size((int)Math.Round(src.Width * rnd), (int)Math.Round(src.Height * rnd));
}
This puts the problem of aspect ratio and dimensions in a separate method.
Systems based on ASCII or a compatible character set use either LF (Line feed, 0x0A, 10 in decimal) or CR (Carriage return, 0x0D, 13 in decimal) individually, or CR followed by LF (CR+LF, 0x0D 0x0A); These characters are based on printer commands: The line feed indicated that one line of paper should feed out of the printer, and a carriage return indicated that the printer carriage should return to the beginning of the current line.
Here is the details.
The great thing about yyyy-mm-dd
date format is that there is no need to extract month()
and year()
, you can do comparisons directly on strings:
SELECT *
FROM your_table
WHERE your_date_column >= '2010-09-01' AND your_date_column <= '2013-08-31';
For Android using a string from a single activity to all the necessary activity. Just like static in java
public final static String TEA_NAME = "TEA_NAME";
Equivalent approach in Kotlin:
class MainActivity : AppCompatActivity() {
companion object {
const val TEA_NAME = "TEA_NAME"
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
}
Another activity where value is needed:
val teaName = MainActivity.TEA_NAME
I had similar issue with <input type="range" />
and I solved it with

<input type="range" id="volume" name="demo"

I have had another issue giving me a 504. It's pretty far out but I'll write it up here for googlers and posterity...
I have a client calling an IIS hosted webservice hosted in another domain (Active Directory). There is not full trust between the client domain and the domain where the web services is hosted. One of the many challenges with the selective trust between these two domains is that Kerberos does not work when calling from one to the other.
In my case I was trying to call a service in another domain where I found out that a SPN was registered. Like this : http/myurl.test.local (just an example)
This forces the call to use Kerberos instead of letting it fall back to NTLM and this gave me a 405 back from the calling server.
After removing the spn and allowing the call to fall back to NTLM, it works fine.
As I said ... this is not something you are likely to run into, as most organizations do not venture into having such a selective trusts between two domains ... But it gives a 504 and caused me a few (more) gray hairs.
Here you will find some working examples. This is also a good example of FileFilter used in JFileChooser.
The basics are, you need to override FileFilter class and write your custom code in its accpet method. The accept method in above example is doing filtration based on file types:
public boolean accept(File file) {
if (file.isDirectory()) {
return true;
} else {
String path = file.getAbsolutePath().toLowerCase();
for (int i = 0, n = extensions.length; i < n; i++) {
String extension = extensions[i];
if ((path.endsWith(extension) && (path.charAt(path.length()
- extension.length() - 1)) == '.')) {
return true;
}
}
}
return false;
}
Or more simpler to use is FileNameFilter which has accept method with filename as argument, so you don't need to get it manually.
How about something like this :
string url = "http://www.example.com/aaa/bbb.jpg";
Uri uri = new Uri(url);
string path_Query = uri.PathAndQuery;
string extension = Path.GetExtension(path_Query);
path_Query = path_Query.Replace(extension, string.Empty);// This will remove extension
If you want to make sure that last row does not wrap and thus size the way you want it, have a look at
td {
white-space: nowrap;
}
import pdb
pdb.debug()
This is used to debug the script. Should be useful to break also.
I want to change the select element's selected option's both value & textContent (what we see) to 'Mango'.
Simplest code that worked is below:
var newValue1 = 'Mango'
var selectElement = document.getElementById('myselectid');
selectElement.options[selectElement.selectedIndex].value = newValue1;
selectElement.options[selectElement.selectedIndex].textContent = newValue1;
Hope that helps someone. Best of luck.

While the other answer is correct, here's the fastest way to just go ahead and configure Meld as your visual diff tool. Just copy/paste this:
git config --global diff.tool meld
git config --global difftool.prompt false
Now run git difftool
in a directory and Meld will be launched for each different file.
Side note: Meld is surprisingly slow at comparing CSV files, and no Linux diff tool I've found is faster than this Windows tool called Compare It! (last updated in 2010).
Use the gcc
compiler. This assumes that you have the developer tools installed.
Here is an example of a recursive algorithm for reversing a singly linked list. On a laptop with the following spec (4G memory, Intel Core i5 2.3GHz CPU, 64 bit Windows 7), this function will run into StackOverflow error for a linked list of size close to 10,000.
My point is that we should use recursion judiciously, always taking into account of the scale of the system. Often recursion can be converted to iterative program, which scales better. (One iterative version of the same algorithm is given at the bottom of the page, it reverses a singly linked list of size 1 million in 9 milliseconds.)
private static LinkedListNode doReverseRecursively(LinkedListNode x, LinkedListNode first){
LinkedListNode second = first.next;
first.next = x;
if(second != null){
return doReverseRecursively(first, second);
}else{
return first;
}
}
public static LinkedListNode reverseRecursively(LinkedListNode head){
return doReverseRecursively(null, head);
}
Iterative Version of the Same Algorithm:
public static LinkedListNode reverseIteratively(LinkedListNode head){
return doReverseIteratively(null, head);
}
private static LinkedListNode doReverseIteratively(LinkedListNode x, LinkedListNode first) {
while (first != null) {
LinkedListNode second = first.next;
first.next = x;
x = first;
if (second == null) {
break;
} else {
first = second;
}
}
return first;
}
public static LinkedListNode reverseIteratively(LinkedListNode head){
return doReverseIteratively(null, head);
}

There is a useful difference between call
and start /wait
when calling regsvr32.exe /s
for example, also referenced by Gary in
in his answer to how-do-i-get-the-application-exit-code-from-a-windows-command-line
call regsvr32.exe /s broken.dll
echo %errorlevel%
will always return 0 but
start /wait regsvr32.exe /s broken.dll
echo %errorlevel%
will return the error level from regsvr32.exe
Need to say, that if you are not in Activity
, but in View
(or have variable of View
type in your scope), there is not need to use WINDOW_SERVICE
. Then you can use at least two ways.
First:
DisplayMetrics dm = yourView.getContext().getResources().getDisplayMetrics();
Second:
DisplayMetrics dm = new DisplayMetrics();
yourView.getDisplay().getMetrics(dm);
All this methods we call here is not deprecated.
If you want to split a string into words, you can use explode() or str_word_count().
I was having the same problem while importing the certificate in local keystore. Whenever i issue the keytool command i got the following error.
Certificate was added to keystore keytool error: java.io.FileNotFoundException: C:\Program Files\Java\jdk1.8.0_151\jre\lib\security (Access is denied)
Following solution work for me.
1) make sure you are running command prompt in Rus as Administrator mode
2) Change your current directory to %JAVA_HOME%\jre\lib\security
3) then Issue the below command
keytool -import -alias "mycertificatedemo" -file "C:\Users\name\Downloads\abc.crt" -keystore cacerts
3) give the password changeit
4) enter y
5) you will see the following message on successful "Certificate was added to keystore"
Make sure you are giving the "cacerts" only in -keystore param value , as i was giving the full path like "C**:\Program Files\Java\jdk1.8.0_151\jre\lib\security**".
Hope this will work

Probably you use Microsoft SQL Server which support Common Table Expressions (CTE) (see http://msdn.microsoft.com/en-us/library/ms190766.aspx) which are very friendly for query optimization. So I suggest you my favor construction:
WITH GetNumberOfPlans(Id,NumberOfPlans) AS (
SELECT tableA.Id, COUNT(tableC.Id)
FROM tableC
RIGHT OUTER JOIN tableA ON tableC.tableAId = tableA.Id
GROUP BY tableA.Id
),GetUserInformation(Id,Name,Owner,ImageUrl,
CompanyImageUrl,NumberOfUsers) AS (
SELECT tableA.Id, tableA.Name, tableB.Username AS Owner, tableB.ImageUrl,
tableB.CompanyImageUrl,COUNT(tableD.UserId),p.NumberOfPlans
FROM tableA
INNER JOIN tableB ON tableB.Id = tableA.Owner
RIGHT OUTER JOIN tableD ON tableD.tableAId = tableA.Id
GROUP BY tableA.Name, tableB.Username, tableB.ImageUrl, tableB.CompanyImageUrl
)
SELECT u.Id,u.Name,u.Owner,u.ImageUrl,u.CompanyImageUrl
,u.NumberOfUsers,p.NumberOfPlans
FROM GetUserInformation AS u
INNER JOIN GetNumberOfPlans AS p ON p.Id=u.Id
After some experiences with CTE you will be find very easy to write code using CTE and you will be happy with the performance.
You should just install python 3.6. I tried it and it worked. Just install that version of python and just do the normal download process (pip install pyaudio
).
There are multiple ways how to present a timespan in the database.
time
This datatype is supported since SQL Server 2008 and is the prefered way to store a TimeSpan
. There is no mapping needed. It also works well with SQL code.
public TimeSpan ValidityPeriod { get; set; }
However, as stated in the original question, this datatype is limited to 24 hours.
datetimeoffset
The datetimeoffset
datatype maps directly to System.DateTimeOffset
. It's used to express the offset between a datetime
/datetime2
to UTC, but you can also use it for TimeSpan
.
However, since the datatype suggests a very specific semantic, so you should also consider other options.
datetime / datetime2
One approach might be to use the datetime
or datetime2
types. This is best in scenarios where you need to process the values in the database directly, ie. for views, stored procedures, or reports. The drawback is that you need to substract the value DateTime(1900,01,01,00,00,00)
from the date to get back the timespan in your business logic.
public DateTime ValidityPeriod { get; set; }
[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
get { return ValidityPeriod - DateTime(1900,01,01,00,00,00); }
set { ValidityPeriod = DateTime(1900,01,01,00,00,00) + value; }
}
bigint
Another approach might be to convert the TimeSpan into ticks and use the bigint
datatype. However, this approach has the drawback that it's cumbersome to use in SQL queries.
public long ValidityPeriod { get; set; }
[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
get { return TimeSpan.FromTicks(ValidityPeriod); }
set { ValidityPeriod = value.Ticks; }
}
varchar(N)
This is best for cases where the value should be readable by humans. You might also use this format in SQL queries by utilizing the CONVERT(datetime, ValidityPeriod)
function. Dependent on the required precision, you will need between 8 and 25 characters.
public string ValidityPeriod { get; set; }
[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
get { return TimeSpan.Parse(ValidityPeriod); }
set { ValidityPeriod = value.ToString("HH:mm:ss"); }
}
Bonus: Period and Duration
Using a string, you can also store NodaTime datatypes, especially Duration
and Period
. The first is basically the same as a TimeSpan, while the later respects that some days and months are longer or shorter than others (ie. January has 31 days and February has 28 or 29; some days are longer or shorter because of daylight saving time). In such cases, using a TimeSpan is the wrong choice.
You can use this code to convert Periods:
using NodaTime;
using NodaTime.Serialization.JsonNet;
internal static class PeriodExtensions
{
public static Period ToPeriod(this string input)
{
var js = JsonSerializer.Create(new JsonSerializerSettings());
js.ConfigureForNodaTime(DateTimeZoneProviders.Tzdb);
var quoted = string.Concat(@"""", input, @"""");
return js.Deserialize<Period>(new JsonTextReader(new StringReader(quoted)));
}
}
And then use it like
public string ValidityPeriod { get; set; }
[NotMapped]
public Period ValidityPeriodPeriod
{
get => ValidityPeriod.ToPeriod();
set => ValidityPeriod = value.ToString();
}
I really like NodaTime
and it often saves me from tricky bugs and lots of headache. The drawback here is that you really can't use it in SQL queries and need to do calculations in-memory.
CLR User-Defined Type
You also have the option to use a custom datatype and support a custom TimeSpan
class directly. See CLR User-Defined Types for details.
The drawback here is that the datatype might not behave well with SQL Reports. Also, some versions of SQL Server (Azure, Linux, Data Warehouse) are not supported.
Value Conversions
Starting with EntityFramework Core 2.1, you have the option to use Value Conversions.
However, when using this, EF will not be able to convert many queries into SQL, causing queries to run in-memory; potentially transfering lots and lots of data to your application.
So at least for now, it might be better not to use it, and just map the query result with Automapper.

Retrieve an object using the tutorial shown in the Flask-SQLAlchemy documentation. Once you have the entity that you want to change, change the entity itself. Then, db.session.commit()
.
For example:
admin = User.query.filter_by(username='admin').first()
admin.email = '[email protected]'
db.session.commit()
user = User.query.get(5)
user.name = 'New Name'
db.session.commit()
Flask-SQLAlchemy is based on SQLAlchemy, so be sure to check out the SQLAlchemy Docs as well.

Most people are using gson : check this
Gson gson = new Gson();
String json = gson.toJson(myObj);
For a group of inputs you can use an improved version based in @mikemaccana's answer
$.fn.isValid = function(){
var validate = true;
this.each(function(){
if(this.checkValidity()==false){
validate = false;
}
});
};
now you can use this to verify if the form is valid:
if(!$(".form-control").isValid){
return;
}
You could use the same technique to get all the error messages:
$.fn.getVelidationMessage = function(){
var message = "";
var name = "";
this.each(function(){
if(this.checkValidity()==false){
name = ($( "label[for=" + this.id + "] ").html() || this.placeholder || this.name || this.id);
message = message + name +":"+ (this.validationMessage || 'Invalid value.')+"\n<br>";
}
})
return message;
}

I came across this thread when I was trying reuse Docker --env-file
s in a shell. Their format is not bash compatible but it is simple: name=value
, no quoting, no substitution. They also ignore blank lines and #
comments.
I couldn't quite get it posix compatible, but here's one that should work in bash-like shells (tested in zsh on OSX 10.12.5 and bash on Ubuntu 14.04):
while read -r l; do export "$(sed 's/=.*$//' <<<$l)"="$(sed -E 's/^[^=]+=//' <<<$l)"; done < <(grep -E -v '^\s*(#|$)' your-env-file)
It will not handle three cases in the example from the docs linked above:
bash: export: `123qwe=bar': not a valid identifier
bash: export: `org.spring.config=something': not a valid identifier
FOO
)The fastest way i've yet found to do this is the following:
private static final String HEXES = "0123456789ABCDEF";
static String getHex(byte[] raw) {
final StringBuilder hex = new StringBuilder(2 * raw.length);
for (final byte b : raw) {
hex.append(HEXES.charAt((b & 0xF0) >> 4)).append(HEXES.charAt((b & 0x0F)));
}
return hex.toString();
}
It's ~ 50x faster than String.format
. if you want to test it:
public class MyTest{
private static final String HEXES = "0123456789ABCDEF";
@Test
public void test_get_hex() {
byte[] raw = {
(byte) 0xd0, (byte) 0x0b, (byte) 0x01, (byte) 0x2a, (byte) 0x63,
(byte) 0x78, (byte) 0x01, (byte) 0x2e, (byte) 0xe3, (byte) 0x6c,
(byte) 0xd2, (byte) 0xb0, (byte) 0x78, (byte) 0x51, (byte) 0x73,
(byte) 0x34, (byte) 0xaf, (byte) 0xbb, (byte) 0xa0, (byte) 0x9f,
(byte) 0xc3, (byte) 0xa9, (byte) 0x00, (byte) 0x1e, (byte) 0xd5,
(byte) 0x4b, (byte) 0x89, (byte) 0xa3, (byte) 0x45, (byte) 0x35,
(byte) 0xd6, (byte) 0x10,
};
int N = 77777;
long t;
{
t = System.currentTimeMillis();
for (int i = 0; i < N; i++) {
final StringBuilder hex = new StringBuilder(2 * raw.length);
for (final byte b : raw) {
hex.append(HEXES.charAt((b & 0xF0) >> 4)).append(HEXES.charAt((b & 0x0F)));
}
hex.toString();
}
System.out.println(System.currentTimeMillis() - t); // 50
}
{
t = System.currentTimeMillis();
for (int i = 0; i < N; i++) {
StringBuilder hex = new StringBuilder(2 * raw.length);
for (byte b : raw) {
hex.append(String.format("%02X", b));
}
hex.toString();
}
System.out.println(System.currentTimeMillis() - t); // 2535
}
}
}
Edit: Just found something just a lil faster and that holds on one line but is not compatible with JRE 9. Use at your own risks
import javax.xml.bind.DatatypeConverter;
DatatypeConverter.printHexBinary(raw);
If the above solutions don't work on ubuntu/linux then you can try this
sudo fuser -k -n tcp port
Run it several times to kill processes on your port of choosing. port could be 3000 for example. You would have killed all the processes if you see no output after running the command
It seems you can (somewhat) control the spacing using padding on the <li> tag.
<style type="text/css">
li { padding-left: 10px; }
</style>
The catch is that it doesn't seem to allow you to scrunch it way-snug like your final example.
For that you could try turning off list-style-type and using •
<ul style="list-style-type: none;">
<li>•Some list text goes here.</li>
</ul>
the best way to calculate the equation is simplified. That is, find the maximum divisor between two numbers and divide:
ex.
1920:1080 maximum common divisor 120 = 16:9
1024:768 maximum common divisor 256 = 4:3
1280:768 maximum common divisor 256 = 5:3
may happen also some approaches
If you look at the output you receive from print()
and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b
):
b'{\n "note":"This file .....
If you fetch the URL using a tool such as curl -v
, you will see that the content type is
Content-Type: application/json; charset=utf-8
So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.
Change the last line of code to this:
info = json.loads(js.decode("utf-8"))
I think you would want to add an 'onSelect' event handler to the initialization of your datepicker so your code gets triggered when the user selects a date. Try it out on jsFiddle
$(document).ready(function(){
// Datepicker
$('#datepicker').datepicker({
dateFormat: 'yy-mm-dd',
inline: true,
minDate: new Date(2010, 1 - 1, 1),
maxDate:new Date(2010, 12 - 1, 31),
altField: '#datepicker_value',
onSelect: function(){
var day1 = $("#datepicker").datepicker('getDate').getDate();
var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1;
var year1 = $("#datepicker").datepicker('getDate').getFullYear();
var fullDate = year1 + "-" + month1 + "-" + day1;
var str_output = "<h1><center><img src=\"/images/a" + fullDate +".png\"></center></h1><br/><br>";
$('#page_output').html(str_output);
}
});
});
Today I was asked this same exercise on pen&paper, so I come up with this function for lists:
def rev(s):
l = len(s)
for i,j in zip(range(l-1, 0, -1), range(l//2)):
s[i], s[j] = s[j], s[i]
return s
which can be used with strings with "".join(rev(list("hello")))
I came up with this three liner.
Essentially, here's what it does:
inp = pd.read_csv('filename.csv') # read input. Add read_csv arguments as needed
columns = pd.DataFrame({'column_names': inp.columns, 'datatypes': inp.dtypes})
columns.to_csv(inp+'columns_list.csv', encoding='utf-8') # encoding is optional
This made my life much easier in trying to generate schemas on the fly. Hope this helps
If the formulas are identical you can use Find and Replace with Match entire cell contents
checked and Look in: Formulas
. Select the range, go into Find and Replace, make your entries and `Replace All.
Or do you mean that there are several formulas with this same form, but different cell references? If so, then one way to go is a regular expression match and replace. Regular expressions are not built into Excel (or VBA), but can be accessed via Microsoft's VBScript Regular Expressions library.
The following function provides the necessary match and replace capability. It can be used in a subroutine that would identify cells with formulas in the specified range and use the formulas as inputs to the function. For formulas strings that match the pattern you are looking for, the function will produce the replacement formula, which could then be written back to the worksheet.
Function RegexFormulaReplace(formula As String)
Dim regex As New RegExp
regex.Pattern = "=\(\(([A-Z]+\d+)-([A-Z]+\d+)\)/([A-Z]+\d+)\)"
' Test if a match is found
If regex.Test(formula) = True Then
RegexFormulaReplace = regex.Replace(formula, "=(EXP((LN($1/$2)/14.32))-1")
Else
RegexFormulaReplace = CVErr(xlErrValue)
End If
Set regex = Nothing
End Function
In order for the function to work, you would need to add a reference to the Microsoft VBScript Regular Expressions 5.5 library. From the Developer
tab of the main ribbon, select VBA
and then References
from the main toolbar. Scroll down to find the reference to the library and check the box next to it.
If you want to kill the Sticky Service,the following command NOT WORKING:
adb shell am force-stop <PACKAGE>
adb shell kill <PID>
The following command is WORKING:
adb shell pm disable <PACKAGE>
If you want to restart the app,you must run command below first:
adb shell pm enable <PACKAGE>
You cannot multiply an integer by a string. To be sure, you could try using the int (short for integer which means whole number) command, like this for example -
firstNumber = int(9)
secondNumber = int(1)
answer = (firstNumber*secondNumber)
Hope that helped :)
The easiest way to be sure that you have created the runnable JAR file correctly, with the appropriate manifest file, is to use Eclipse to build it for you. In your Eclipse project, you basically just select File/Export from the menu, and follow the prompts.
That way, you can be sure that your JAR file is correct and will know to look elsewhere if there is still an issue. The process is described in full in FAQ How do I create an executable JAR file for a stand-alone SWT program?.
It depends. If it's a dynamically allocated array, that is, you created it calling malloc, then as others suggest you must either save the size of the array/number of elements somewhere or have a sentinel (a struct with a special value, that will be the last one).
If it's a static array, you can sizeof it's size/the size of one element. For example:
int array[10], array_size;
...
array_size = sizeof(array)/sizeof(int);
Note that, unless it's global, this only works in the scope where you initialized the array, because if you past it to another function it gets decayed to a pointer.
Hope it helps.
GPS is generally more accurate than network but sometimes GPS is not available, therefore you might need to switch between the two.
A good start might be to look at the android dev site. They had a section dedicated to determining user location and it has all the code samples you need.
http://developer.android.com/guide/topics/location/obtaining-user-location.html
Not exactly. The h1.hc-reform > p
means "any p
exactly one level underneath h1.hc-reform
".
What you want is h1.hc-reform + p
. Of course, that might cause some issues in older versions of Internet Explorer; if you want to make the page compatible with older IEs, you'll be stuck with either adding a class manually to the paragraphs or using some JavaScript (in jQuery, for example, you could do something like $('h1.hc-reform').next('p').addClass('first-paragraph')
).

Use pointer-events CSS style. (as Jason MacDonald suggested)
See MDN https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events. Its supported in most browsers.
Simple adding "disabled" attribute to anchor will do the job if you have global CSS rule like following:
a[disabled], a[disabled]:hover {
pointer-events: none;
color: #e1e1e1;
}
You have probably installed Eclipse for Java Developers instead of Eclipse IDE for Enterprise Java Developers, server tab and some other are not available.
You don't have to uninstall. Just rerun eclipse-inst-win64.exe and choose Java EE IDE
Changing 'java.library.path' variable at runtime is not enough because it is read only once by JVM. You have to reset it like:
System.setProperty("java.library.path", path);
//set sys_paths to null
final Field sysPathsField = ClassLoader.class.getDeclaredField("sys_paths");
sysPathsField.setAccessible(true);
sysPathsField.set(null, null);
Please, take a loot at: Changing Java Library Path at Runtime.
If you don't want to use the KnockoutValidation library you can write your own. Here's an example for a Mandatory field.
Add a javascript class with all you KO extensions or extenders, and add the following:
ko.extenders.required = function (target, overrideMessage) {
//add some sub-observables to our observable
target.hasError = ko.observable();
target.validationMessage = ko.observable();
//define a function to do validation
function validate(newValue) {
target.hasError(newValue ? false : true);
target.validationMessage(newValue ? "" : overrideMessage || "This field is required");
}
//initial validation
validate(target());
//validate whenever the value changes
target.subscribe(validate);
//return the original observable
return target;
};
Then in your viewModel extend you observable by:
self.dateOfPayment: ko.observable().extend({ required: "" }),
There are a number of examples online for this style of validation.
A today extension would be the most fitting solution.
Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.
typeof
condition is used to check variable type, if you are check variable type in if-else condition
e.g.
if(typeof Varaible_Name "undefined")
{
}
@
Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" .... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).
Just lock and unlock the android solved my issue then
adb reverse tcp:8081 tcp:8081
You can use CSS white-space Property
to achieve this.
white-space: nowrap
A CustomValidator would also work here:
<asp:CustomValidator runat="server"
ID="valDateRange"
ControlToValidate="txtDatecompleted"
onservervalidate="valDateRange_ServerValidate"
ErrorMessage="enter valid date" />
Code-behind:
protected void valDateRange_ServerValidate(object source, ServerValidateEventArgs args)
{
DateTime minDate = DateTime.Parse("1000/12/28");
DateTime maxDate = DateTime.Parse("9999/12/28");
DateTime dt;
args.IsValid = (DateTime.TryParse(args.Value, out dt)
&& dt <= maxDate
&& dt >= minDate);
}
With support of default methods in interface since launch of Java 8, the gap between interface and abstract classes has been reduced but still they have major differences.
Variables in interface are public static final. But abstract class can have other type of variables like private, protected etc
Methods in interface are public or public static but methods in abstract class can be private and protected too
Use abstract class to establish relation between interrelated objects. Use interface to establish relation between unrelated classes.
Have a look at this article for special properties of interface in java 8. static modifier for default methods in interface causes compile time error in derived error if you want to use @override.
This article explains why default methods have been introduced in java 8 : To enhance the Collections API in Java 8 to support lambda expressions.
Have a look at oracle documentation too to understand the differences in better way.
Have a look at this related SE questions with code example to understand things in better way:
How should I have explained the difference between an Interface and an Abstract class?
Another method is to expose a web-accessible resource, though this will allow any website to test if your extension is installed.
Suppose your extension's ID is aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
, and you add a file (say, a transparent pixel image) as test.png
in your extension's files.
Then, you expose this file to the web pages with web_accessible_resources
manifest key:
"web_accessible_resources": [
"test.png"
],
In your web page, you can try to load this file by its full URL (in an <img>
tag, via XHR, or in any other way):
chrome-extension://aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/test.png
If the file loads, then the extension is installed. If there's an error while loading this file, then the extension is not installed.
// Code from https://groups.google.com/a/chromium.org/d/msg/chromium-extensions/8ArcsWMBaM4/2GKwVOZm1qMJ
function detectExtension(extensionId, callback) {
var img;
img = new Image();
img.src = "chrome-extension://" + extensionId + "/test.png";
img.onload = function() {
callback(true);
};
img.onerror = function() {
callback(false);
};
}
Of note: if there is an error while loading this file, said network stack error will appear in the console with no possibility to silence it. When Chromecast used this method, it caused quite a bit of controversy because of this; with the eventual very ugly solution of simply blacklisting very specific errors from Dev Tools altogether by the Chrome team.
Important note: this method will not work in Firefox WebExtensions. Web-accessible resources inherently expose the extension to fingerprinting, since the URL is predictable by knowing the ID. Firefox decided to close that hole by assigning an instance-specific random URL to web accessible resources:
The files will then be available using a URL like:
moz-extension://<random-UUID>/<path/to/resource>
This UUID is randomly generated for every browser instance and is not your extension's ID. This prevents websites from fingerprinting the extensions a user has installed.
However, while the extension can use runtime.getURL()
to obtain this address, you can't hard-code it in your website.
You will need to add the application.properties
file in your classpath.
If you are using Maven or Gradle, you can just put the file under src/main/resources
.
If you are not using Maven or any other build tools, put that under your src folder and you should be fine.
Then you can just add an entry server.port = xxxx
in the properties file.
Take a look at this project it outputs some interesting stats about keyspaces based on regexs and prefixes. It uses the DEBUG OBJECT
command and scans the db, identifying groups of keys and estimating the percentage of space they're taking up.
https://github.com/snmaynard/redis-audit
Output looks like this:
Summary
---------------------------------------------------+--------------+-------------------+---------------------------------------------------
Key | Memory Usage | Expiry Proportion | Last Access Time
---------------------------------------------------+--------------+-------------------+---------------------------------------------------
notification_3109439 | 88.14% | 0.0% | 2 minutes
user_profile_3897016 | 11.86% | 99.98% | 20 seconds
---------------------------------------------------+--------------+-------------------+---------------------------------------------------
Or this this one: https://github.com/sripathikrishnan/redis-rdb-tools which does a full analysis on the entire keyspace by analyzing a dump.rdb file offline. This one works well also. It can give you the avg/min/max size for the entries in your db, and will even do it based on a prefix.
Just got done wasting a day and a half with DBCP. Even though I'm using the latest DBCP release, I ran into exactly the same problems as j pimmel did. I would not recommend DBCP at all, especially it's knack of throwing connections out of the pool when the DB goes away, its inability to reconnect when the DB comes back and its inability to dynamically add connection objects back into the pool (it hangs forever on a post JDBCconnect I/O socket read)
I'm switching over to C3P0 now. I've used that in previous projects and it worked and performed like a charm.
First open a console then cd to where you've downloaded your file like some-package.whl and use
pip install some-package.whl
Note: if pip.exe is not recognized, you may find it in the "Scripts" directory from where python has been installed. I have multiple Python installations, and needed to use the pip associated with Python 3 to install a version 3 wheel.
If pip is not installed, and you are using Windows: How to install pip on Windows?
I would not advise hacking browser-specific things manually with JS. Either use a javascript library like "prototype" or "jquery", which will handle all the specific issues transparently.
Or use these libs to determine the browser type if you really must.
You can allow the server to reuse an address with allow_reuse_address
.
Whether the server will allow the reuse of an address. This defaults to
False
, and can be set in subclasses to change the policy.
import SimpleHTTPServer, SocketServer
PORT = 8000
httpd = SocketServer.TCPServer(("", PORT), SimpleHTTPServer.SimpleHTTPRequestHandler)
httpd.allow_reuse_address = True
print "Serving at port", PORT
httpd.serve_forever()
Splat Method with Calculations
If you choose splat method, beware calculations that are made using other parameters. In practice, sometimes I have to set variables first then create the hash table. Also, the format doesn't require single quotes around the key value or the semi-colon (as mentioned above).
Example of a call to a function that creates an Excel spreadsheet
$title = "Cut-off File Processing on $start_date_long_str"
$title_row = 1
$header_row = 2
$data_row_start = 3
$data_row_end = $($data_row_start + $($file_info_array.Count) - 1)
# use parameter hash table to make code more readable
$params = @{
title = $title
title_row = $title_row
header_row = $header_row
data_row_start = $data_row_start
data_row_end = $data_row_end
}
$xl_wksht = Create-Excel-Spreadsheet @params
Note: The file array contains information that will affect how the spreadsheet is populated.
I would like to expand the answer of Jason Bunting
like this
ActionResult action = new SampelController().Index(2, "text");
return action;
And Eli will be here for something idea on how to make it generic variable

To add to svick's answer, the -m
option simply adds a message to your stash, and is entirely optional. Thus, the command
git stash push [paths you wish to stash]
is perfectly valid. So for instance, if I want to only stash changes in the src/
directory, I can just run
git stash push src/
For those interested, this is code for creating SHA-256 hash using sjcl
:
import sjcl from 'sjcl'
const myString = 'Hello'
const myBitArray = sjcl.hash.sha256.hash(myString)
const myHash = sjcl.codec.hex.fromBits(myBitArray)
Hmmm $array = json_decode($json, true);
will make your string an array which is easy to print nicely with print_r($array, true);
But if you really want to prettify your json... Check this out
I added a directory to svn, then I accidentally deleted the .svn folder within.
I used
svn delete --keep-local folderName
to fix my problem.
When user reduces window size horizontally and this causes floats to stack vertically, remove the floats and on the second div (that was a float) use margin-top: -123px (your value) and margin-left: 444px (your value) to position the divs as they appeared with floats. When done this way, when the window narrows, the right-side div stays in place and disappears when page is too narrow to include it. ... which (to me) is better than having the right-side div "jump" down below the left-side div when the browser window is narrowed by the user.
Signalling a pod on config map update is a feature in the works (https://github.com/kubernetes/kubernetes/issues/22368).
You can always write a custom pid1 that notices the confimap has changed and restarts your app.
You can also eg: mount the same config map in 2 containers, expose a http health check in the second container that fails if the hash of config map contents changes, and shove that as the liveness probe of the first container (because containers in a pod share the same network namespace). The kubelet will restart your first container for you when the probe fails.
Of course if you don't care about which nodes the pods are on, you can simply delete them and the replication controller will "restart" them for you.
You can try something like this. Here on click of image button I toggle the imageview.
holder.imgitem.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
if(!onclick){
mSparseBooleanArray.put((Integer) view.getTag(), true);
holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_delete_overlay_com);
onclick=true;}
else if(onclick)
{
mSparseBooleanArray.put((Integer) view.getTag(), false);
holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_selection_com);
onclick=false;
}
}
});
Do you want to do something like this ?
JTextField mTextField = new JTextField();
mTextField.addKeyListener(new KeyAdapter() {
@Override
public void keyPressed(KeyEvent e) {
if(e.getKeyCode() == KeyEvent.VK_ENTER){
// something like...
//mTextField.getText();
// or...
//mButton.doClick();
}
}
});
In your Apache .htaccess file:
#Create filter to match files you want to cache
<Files *.js>
Header add "Cache-Control" "max-age=604800"
</Files>
I wrote about it here also:
http://betterexplained.com/articles/how-to-optimize-your-site-with-http-caching/
adding to CMS's answer, this is a more generic approach of toggle_visibility
I've just used myself:
function toggle_visibility(className,display) {
var elements = getElementsByClassName(document, className),
n = elements.length;
for (var i = 0; i < n; i++) {
var e = elements[i];
if(display.length > 0) {
e.style.display = display;
} else {
if(e.style.display == 'block') {
e.style.display = 'none';
} else {
e.style.display = 'block';
}
}
}
}
For some time, the following should work:
Dapper.DefaultTypeMap.MatchNamesWithUnderscores = true;
When you
import App from './App.jsx';
That means it will import whatever you export default
. You can rename App
class inside App.jsx
to whatever you want as long as you export default
it will work but you can only have one export default.
So you only need to export default App
and you don't need to export the rest.
If you still want to export the rest of the components, you will need named export.

git 2.7 (Q4 2015) will introduce branch sorting using directly git branch
:
See commit aa3bc55, commit aedcb7d, commit 1511b22, commit f65f139, ... (23 Sep 2015), commit aedcb7d, commit 1511b22, commit ca41799 (24 Sep 2015), and commit f65f139, ... (23 Sep 2015) by Karthik Nayak (KarthikNayak
).
(Merged by Junio C Hamano -- gitster
-- in commit 7f11b48, 15 Oct 2015)
In particular, commit aedcb7d:
branch.c
: use 'ref-filter
' APIs
Make 'branch.c
' use 'ref-filter
' APIs for iterating through refs sorting. This removes most of the code used in 'branch.c
' replacing it
with calls to the 'ref-filter
' library.
It adds the option --sort=<key>
:
Sort based on the key given.
Prefix-
to sort in descending order of the value.
You may use the
--sort=<key>
option multiple times, in which case the last key becomes the primary key.
The keys supported are the same as those in
git for-each-ref
.
Sort order defaults to sorting based on the full refname (includingrefs/...
prefix). This lists detached HEAD (if present) first, then local branches and finally remote-tracking branches.
Here:
git branch --sort=-committerdate
Or (see below with Git 2.19)
# if you are sure to /always/ want to see branches ordered by commits:
git config --global branch.sort -committerdate
git branch

(Merged by Junio C Hamano -- gitster

When sorting as per numerical values (e.g.
--sort=objectsize
) there is no fallback comparison when both refs hold the same value. This can cause unexpected results (i.e. the order of listing refs with equal values cannot be pre-determined) as pointed out by Johannes Sixt ($gmane/280117).
Hence, fallback to alphabetical comparison based on the refname whenever the other criterion is equal.
$ git branch --sort=objectsize
* (HEAD detached from fromtag)
branch-two
branch-one
master
With Git 2.19, the sort order can be set by default.
git branch
supports a config branch.sort
, like git tag
, which already had a config tag.sort
.
See commit 560ae1c (16 Aug 2018) by Samuel Maftoul (``).
(Merged by Junio C Hamano -- gitster

branch.sort:
This variable controls the sort ordering of branches when displayed by
git-branch
.
Without the "--sort=<value>
" option provided, the value of this variable will be used as the default.
To list remote branches, use git branch -r --sort=objectsize
. The -r
flag causes it to list remote branches instead of local branches.
With Git 2.27 (Q2 2020), "git branch
" and other "for-each-ref
" variants accepted multiple --sort=<key>
options in the increasing order of precedence, but it had a few breakages around "--ignore-case
" handling, and tie-breaking with the refname, which have been fixed.
See commit 7c5045f, commit 76f9e56 (03 May 2020) by Jeff King (peff

: fallback on alphabetical comparison", 2015-10-30, Git v2.7.0-rc0 -- merge listed in batch #10) taught ref-filter's sort to fallback to comparing refnames.
But it did it at the wrong level, overriding the comparison result for a single "--sort
" key from the user, rather than after all sort keys have been exhausted.
This worked correctly for a single "
--sort
" option, but not for multiple ones.
We'd break any ties in the first key with the refname and never evaluate the second key at all.
To make matters even more interesting, we only applied this fallback sometimes!
For a field like "taggeremail
" which requires a string comparison, we'd truly return the result ofstrcmp()
, even if it was 0.
But for numerical "value
" fields like "taggerdate
", we did apply the fallback. And that's why our multiple-sort test missed this: it usestaggeremail
as the main comparison.
So let's start by adding a much more rigorous test. We'll have a set of commits expressing every combination of two tagger emails, dates, and refnames. Then we can confirm that our sort is applied with the correct precedence, and we'll be hitting both the string and value comparators.
That does show the bug, and the fix is simple: moving the fallback to the outer
compare_refs()
function, after allref_sorting
keys have been exhausted.
Note that in the outer function we don't have an
"ignore_case"
flag, as it's part of each individualref_sorting
element. It's debatable what such a fallback should do, since we didn't use the user's keys to match.
But until now we have been trying to respect that flag, so the least-invasive thing is to try to continue to do so.
Since all callers in the current code either set the flag for all keys or for none, we can just pull the flag from the first key. In a hypothetical world where the user really can flip the case-insensitivity of keys separately, we may want to extend the code to distinguish that case from a blanket "--ignore-case
".
The implementation of "git branch --sort
"(man) wrt the detached HEAD display has always been hacky, which has been cleaned up with Git 2.31 (Q1 2021).
See commit 4045f65, commit 2708ce6, commit 7c269a7, commit d094748, commit 75c50e5 (07 Jan 2021), and commit 08bf6a8, commit ffdd02a (06 Jan 2021) by Ævar Arnfjörð Bjarmason (avar

branch
: show "HEAD detached" first under reverse sortSigned-off-by: Ævar Arnfjörð Bjarmason
Change the output of the likes of "
git branch -l --sort=-objectsize
"(man) to show the "(HEAD detached at <hash>)
" message at the start of the output.
Before thecompare_detached_head()
function added in a preceding commit we'd emit this output as an emergent effect.It doesn't make any sense to consider the objectsize, type or other non-attribute of the "
(HEAD detached at <hash>)
" message for the purposes of sorting.
Let's always emit it at the top instead.
The only reason it was sorted in the first place is because we're injecting it into the ref-filter machinery sobuiltin/branch.c
doesn't need to do its own "am I detached?" detection.
I assume that by Linux console you mean Bash.
If X

There are two ways to add references using VBA. .AddFromGuid(Guid, Major, Minor)
and .AddFromFile(Filename)
. Which one is best depends on what you are trying to add a reference to. I almost always use .AddFromFile
because the things I am referencing are other Excel VBA Projects and they aren't in the Windows Registry.
The example code you are showing will add a reference to the workbook the code is in. I generally don't see any point in doing that because 90% of the time, before you can add the reference, the code has already failed to compile because the reference is missing. (And if it didn't fail-to-compile, you are probably using late binding and you don't need to add a reference.)
If you are having problems getting the code to run, there are two possible issues.
Aside from that, if you can be a little more clear on what your question is or what you are trying to do that isn't working, I could give a more specific answer.
Check this post in lifehacker : Geek to Live: Back up Gmail with fetchmail . It uses a command line program. Check and see if it helps. BTW why are you using command line when there are many other nice alternatives?
I had similar problem, but in folder which I wanted to move I had files which I was not tracking.
let's say I had files
a/file1
a/untracked1
b/file2
b/untracked2
And I wanted to move only tracked files to subfolder subdir
, so the goal was:
subdir/a/file1
subdir/a/untracked1
subdir/b/file2
subdir/b/untracked2
what I had done was:
mkdir tmpdir && mv a b tmpdir
git checkout a b
mkdir subdir && mv a b subdir
git add --update
with directory change trick): git add subdir
(normally this would add even untracked files - this would require creating .gitignore
file)git status
shows now only moved filesmv tmpdir/* subdir
git status
looks like we executed git mv
:)You can use re.escape():
re.escape(string) Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.
>>> import re
>>> re.escape('^a.*$')
'\\^a\\.\\*\\$'
If you are using a Python version < 3.7, this will escape non-alphanumerics that are not part of regular expression syntax as well.
If you are using a Python version < 3.7 but >= 3.3, this will escape non-alphanumerics that are not part of regular expression syntax, except for specifically underscore (_
).
There are already great answers about the advantages of using list initialization, however my personal rule of thumb is NOT to use curly braces whenever possible, but instead make it dependent on the conceptual meaning:
In my experience, this ruleset can be applied much more consistently than using curly braces by default, but having to explicitly remember all the exceptions when they can't be used or have a different meaning than the "normal" function-call syntax with parenthesis (calls a different overload).
It e.g. fits nicely with standard library-types like std::vector
:
vector<int> a{10,20}; //Curly braces -> fills the vector with the arguments
vector<int> b(10,20); //Parentheses -> uses arguments to parametrize some functionality,
vector<int> c(it1,it2); //like filling the vector with 10 integers or copying a range.
vector<int> d{}; //empty braces -> default constructs vector, which is equivalent
//to a vector that is filled with zero elements
I always go back to this article SQL Server 2005 XQuery and XML-DML - Part 1 to know how to use the XML features in SQL Server 2005.
For basic XPath know-how, I'd recommend the W3Schools tutorial.
It is fairly common to use an "x" or "ext" to indicate extensions, so allow 15 characters (for full international support) plus 3 (for "ext") plus 4 (for the extension itself) giving a total of 22 characters. That should keep you safe.
Alternatively, normalise on input so any "ext" gets translated to "x", giving a maximum of 20.
It's creating a size 0
bitfield if the condition is false, but a size -1
(-!!1
) bitfield if the condition is true/non-zero. In the former case, there is no error and the struct is initialized with an int member. In the latter case, there is a compile error (and no such thing as a size -1
bitfield is created, of course).
content
doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.
Another problem with your code is "
inside a "
block. You should mix '
and "
(class='headingDetail'
).
If content
did support HTML you could end up in an infinite loop where content
is added inside content
.
This works for me:
git rm -r --cached --ignore-unmatch folder_name
--ignore-unmatch
is important here, without that option git will exit with error on the first file not in the index.
This is actually a bit of a perpetuated falsehood. While it is true that C programs are frequently faster, this is not always the case, especially if the C programmer isn't very good at it.
One big glaring hole that people tend to forget about is when the program has to block for some sort of IO, such as user input in any GUI program. In these cases, it doesn't really matter what language you use since you are limited by the rate at which data can come in rather than how fast you can process it. In this case, it doesn't matter much if you are using C, Java, C# or even Perl; you just cannot go any faster than the data can come in.
The other major thing is that using garbage collection and not using proper pointers allows the virtual machine to make a number of optimizations not available in other languages. For instance, the JVM is capable of moving objects around on the heap to defragment it. This makes future allocations much faster since the next index can simply be used rather than looking it up in a table. Modern JVMs also don't have to actually deallocate memory; instead, they just move the live objects around when they GC and the spent memory from the dead objects is recovered essentially for free.
This also brings up an interesting point about C and even more so in C++. There is something of a design philosophy of "If you don't need it, you don't pay for it." The problem is that if you do want it, you end up paying through the nose for it. For instance, the vtable implementation in Java tends to be a lot better than C++ implementations, so virtual function calls are a lot faster. On the other hand, you have no choice but to use virtual functions in Java and they still cost something, but in programs that use a lot of virtual functions, the reduced cost adds up.
You can add the following JS script
<script>
function myfunction(event) {
alert('Checked radio with ID = ' + event.target.id);
}
document.querySelectorAll("input[name='gun']").forEach((input) => {
input.addEventListener('change', myfunction);
});
</script>
you will most likely need to authenticate if you're working in production sort of environments. You can use something like this to authenticate against the correct database with appropriate credentials.
mongoimport -d db_name -c collection_name --type csv --file filename.csv --headerline --host hostname:portnumber --authenticationDatabase admin --username 'iamauser' --password 'pwd123'
mode con:cols=[whatever you want] lines=[whatever you want].
The unit is the number of characters that fit in the command prompt, eg.
mode con:cols=80 lines=100
will make the command prompt 80 ASCII chars of width and 100 of height
In order to solve this problem, I recognize two solutions:
The first one goes with AJAX, with which you'll have to load the template from another file and just add everytime you want with .clone()
.
$.get('url/to/template', function(data) {
temp = data
$('.search').keyup(function() {
$('.list-items').html(null);
$.each(items, function(index) {
$(this).append(temp.clone())
});
});
});
Take into account that the event should be added once the ajax has completed to be sure the data is available!
The second one would be to directly add it anywhere in the original html, select it and hide it in jQuery:
temp = $('.list_group_item').hide()
You can after add a new instance of the template with
$('.search').keyup(function() {
$('.list-items').html(null);
$.each(items, function(index) {
$(this).append(temp.clone())
});
});
Same as the previous one, but if you don't want the template to remain there, but just in the javascript, I think you can use (have not tested it!) .detach()
instead of hide.
temp = $('.list_group_item').detach()
.detach()
removes elements from the DOM while keeping the data and events alive (.remove() does not!).
If you want to use SimpleDateFormat
, you could write:
private final SimpleDateFormat sdf =
new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
{ sdf.setTimeZone(TimeZone.getTimeZone("GMT")); }
private long parseTimeToMillis(final String time) throws ParseException
{ return sdf.parse("1970-01-01 " + time).getTime(); }
But a custom method would be much more efficient. SimpleDateFormat
, because of all its calendar support, time-zone support, daylight-savings-time support, and so on, is pretty slow. The slowness is worth it if you actually need some of those features, but since you don't, it might not be. (It depends how often you're calling this method, and whether efficiency is a concern for your application.)
Also, SimpleDateFormat
is non-thread-safe, which is sometimes a pain. (Without knowing anything about your application, I can't guess whether that matters.)
Personally, I'd probably write a custom method.
for (int i = 0; i < list.length; i++) {
if (list.get(i) .getName().equalsIgnoreCase("myName")) {
System.out.println(i);
break;
}
}
When you hit on the submit button, the page is sent to the server. If you want to send it async, you can do it with ajax.
UML Studio does this quite well in my experience, and will run in "freeware mode" for small projects.
For MAMP
ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock
UPDATE: Every time my computer restarts I have to enter this command, so I created a shortcut.
Do the following in terminal type:
~: vi ~/.profile
Add
alias ...='source ~/.profile'
alias sockit='sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock'
Save.
In terminal type:
~: ...
to source the .profile config.
Now in terminal you can just type
~: sockit
I won't quote the entire page but the whole manual on optimisation is available here: http://gcc.gnu.org/onlinedocs/gcc-4.4.3/gcc/Optimize-Options.html#Optimize-Options
From the sounds of it you want at least -O0
, the default, and:
-fmudflap -fmudflapth -fmudflapir
For front-ends that support it (C and C++), instrument all risky pointer/array dereferencing operations, some standard library string/heap functions, and some other associated constructs with range/validity tests. Modules so instrumented should be immune to buffer overflows, invalid heap use, and some other classes of C/C++ programming errors. The instrumentation relies on a separate runtime library (libmudflap), which will be linked into a program if -fmudflap is given at link time. Run-time behavior of the instrumented program is controlled by the MUDFLAP_OPTIONS environment variable. See env MUDFLAP_OPTIONS=-help a.out for its options.
The source files of your programs are compiled into object files, and then the linker links those object files together, producing an executable file including your architecture's machine codes.
Both object file and executable file involves architecture's machine code in the form of printable and non-printable characters when it's opened by a text editor.
Nonetheless, the dichotomy between the files is that the object file(s) may contain unresolved external references (such as printf
, for instance). So, it may need to be linked against other object files.. That is to say, the unresolved external references are needed to be resolved in order to get the decent runnable executable file by linking with other object files such as C/C++ runtime library's.
You simply have to set the state
of the your button self.x
to normal
:
self.x['state'] = 'normal'
or
self.x.config(state="normal")
This code would go in the callback for the event that will cause the Button to be enabled.
Also, the right code should be:
self.x = Button(self.dialog, text="Download", state=DISABLED, command=self.download)
self.x.pack(side=LEFT)
The method pack
in Button(...).pack()
returns None
, and you are assigning it to self.x
. You actually want to assign the return value of Button(...)
to self.x
, and then, in the following line, use self.x.pack()
.
Use wildcard, e.g. replace 2008
with *
:
df = sqlContext.read
.format("com.databricks.spark.csv")
.option("header", "true")
.load("../Downloads/*.csv") // <-- note the star (*)
// these lines are equivalent in Spark 2.0
spark.read.format("csv").option("header", "true").load("../Downloads/*.csv")
spark.read.option("header", "true").csv("../Downloads/*.csv")
Notes:
Replace format("com.databricks.spark.csv")
by using format("csv")
or csv
method instead. com.databricks.spark.csv
format has been integrated to 2.0.
Use spark
not sqlContext
This is what a constant expression in Java looks like:
package com.mycompany.mypackage;
public class MyLinks {
// constant expression
public static final String GUESTBOOK_URL = "/guestbook";
}
You can use it with annotations as following:
import com.mycompany.mypackage.MyLinks;
@WebServlet(urlPatterns = {MyLinks.GUESTBOOK_URL})
public class GuestbookServlet extends HttpServlet {
// ...
}
This error is caused when you have enabled paging in Grid view. If you want to delete a record from grid then you have to do something like this.
int index = Convert.ToInt32(e.CommandArgument);
int i = index % 20;
// Here 20 is my GridView's Page Size.
GridViewRow row = gvMainGrid.Rows[i];
int id = Convert.ToInt32(gvMainGrid.DataKeys[i].Value);
new GetData().DeleteRecord(id);
GridView1.DataSource = RefreshGrid();
GridView1.DataBind();
Hope this answers the question.
I had the same issue. I'm running a java rest app on a jboss server. But I think the solution is similar on an ASP .NET webapp.
Firefox makes a pre call to your server / rest url to check which options are allowed. That is the "OPTIONS" request which your server doesn't reply to accordingly. If this OPTIONS call is replied correct a second call is performed which is the actual "POST" request with json content.
This only happens when performing a cross-domain call. In your case calling 'http://localhost:16329/Hello
' instead of calling a url path under the same domain '/Hello'
If you intend to make a cross domain call you have to enhance your rest service class with an annotated method the supports a "OPTIONS" http request. This is the according java implementation:
@Path("/rest")
public class RestfulService {
@POST
@Path("/Hello")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.TEXT_PLAIN)
public string HelloWorld(string name)
{
return "hello, " + name;
}
//THIS NEEDS TO BE ADDED ADDITIONALLY IF MAKING CROSS-DOMAIN CALLS
@OPTIONS
@Path("/Hello")
@Produces(MediaType.TEXT_PLAIN+ ";charset=utf-8")
public Response checkOptions(){
return Response.status(200)
.header("Access-Control-Allow-Origin", "*")
.header("Access-Control-Allow-Headers", "Content-Type")
.header("Access-Control-Allow-Methods", "POST, OPTIONS") //CAN BE ENHANCED WITH OTHER HTTP CALL METHODS
.build();
}
}
So I guess in .NET you have to add an additional method annotated with
[WebInvoke(
Method = "OPTIONS",
UriTemplate = "Hello",
ResponseFormat = WebMessageFormat.)]
where the following headers are set
.header("Access-Control-Allow-Origin", "*")
.header("Access-Control-Allow-Headers", "Content-Type")
.header("Access-Control-Allow-Methods", "POST, OPTIONS")
You'll have to jailbreak your device.
As written, your function accepts only two ranges as arguments.
To allow for a variable number of ranges to be used in the function, you need to declare a ParamArray variant array in your argument list. Then, you can process each of the ranges in the array in turn.
For example,
Function myAdd(Arg1 As Range, ParamArray Args2() As Variant) As Double
Dim elem As Variant
Dim i As Long
For Each elem In Arg1
myAdd = myAdd + elem.Value
Next elem
For i = LBound(Args2) To UBound(Args2)
For Each elem In Args2(i)
myAdd = myAdd + elem.Value
Next elem
Next i
End Function
This function could then be used in the worksheet to add multiple ranges.
For your function, there is the question of which of the ranges (or cells) that can passed to the function are 'Sessions' and which are 'Customers'.
The easiest case to deal with would be if you decided that the first range is Sessions and any subsequent ranges are Customers.
Function calculateIt(Sessions As Range, ParamArray Customers() As Variant) As Double
'This function accepts a single Sessions range and one or more Customers
'ranges
Dim i As Long
Dim sessElem As Variant
Dim custElem As Variant
For Each sessElem In Sessions
'do something with sessElem.Value, the value of each
'cell in the single range Sessions
Debug.Print "sessElem: " & sessElem.Value
Next sessElem
'loop through each of the one or more ranges in Customers()
For i = LBound(Customers) To UBound(Customers)
'loop through the cells in the range Customers(i)
For Each custElem In Customers(i)
'do something with custElem.Value, the value of
'each cell in the range Customers(i)
Debug.Print "custElem: " & custElem.Value
Next custElem
Next i
End Function
If you want to include any number of Sessions ranges and any number of Customers range, then you will have to include an argument that will tell the function so that it can separate the Sessions ranges from the Customers range.
This argument could be set up as the first, numeric, argument to the function that would identify how many of the following arguments are Sessions ranges, with the remaining arguments implicitly being Customers ranges. The function's signature would then be:
Function calculateIt(numOfSessionRanges, ParamAray Args() As Variant)
Or it could be a "guard" argument that separates the Sessions ranges from the Customers ranges. Then, your code would have to test each argument to see if it was the guard. The function would look like:
Function calculateIt(ParamArray Args() As Variant)
Perhaps with a call something like:
calculateIt(sessRange1,sessRange2,...,"|",custRange1,custRange2,...)
The program logic might then be along the lines of:
Function calculateIt(ParamArray Args() As Variant) As Double
...
'loop through Args
IsSessionArg = True
For i = lbound(Args) to UBound(Args)
'only need to check for the type of the argument
If TypeName(Args(i)) = "String" Then
IsSessionArg = False
ElseIf IsSessionArg Then
'process Args(i) as Session range
Else
'process Args(i) as Customer range
End if
Next i
calculateIt = <somevalue>
End Function
FAST "FROM" AND "TO" METHODS
I am late to the party, but I compounded previous answers and improved over them. I think these two methods are faster than any others posted so far. I was able to convert 1,000,000 numbers from and to base 36 in under 400ms in a single core machine.
Example below is for base 62. Change the BaseChars
array to convert from and to any other base.
private static readonly char[] BaseChars =
"0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz".ToCharArray();
private static readonly Dictionary<char, int> CharValues = BaseChars
.Select((c,i)=>new {Char=c, Index=i})
.ToDictionary(c=>c.Char,c=>c.Index);
public static string LongToBase(long value)
{
long targetBase = BaseChars.Length;
// Determine exact number of characters to use.
char[] buffer = new char[Math.Max(
(int) Math.Ceiling(Math.Log(value + 1, targetBase)), 1)];
var i = buffer.Length;
do
{
buffer[--i] = BaseChars[value % targetBase];
value = value / targetBase;
}
while (value > 0);
return new string(buffer, i, buffer.Length - i);
}
public static long BaseToLong(string number)
{
char[] chrs = number.ToCharArray();
int m = chrs.Length - 1;
int n = BaseChars.Length, x;
long result = 0;
for (int i = 0; i < chrs.Length; i++)
{
x = CharValues[ chrs[i] ];
result += x * (long)Math.Pow(n, m--);
}
return result;
}
EDIT (2018-07-12)
Fixed to address the corner case found by @AdrianBotor (see comments) converting 46655 to base 36. This is caused by a small floating-point error calculating Math.Log(46656, 36)
which is exactly 3, but .NET returns 3 + 4.44e-16
, which causes an extra character in the output buffer.
Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.
I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.
If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.
Also making aware of interactions between clock() and usleep(). usleep() suspends the program, and clock() only measures the time the program is running.
If might be better off to use gettimeofday() as mentioned here
All you need to do is use the file object as an iterator.
for line in open("log.txt"):
do_something_with(line)
Even better is using context manager in recent Python versions.
with open("log.txt") as fileobject:
for line in fileobject:
do_something_with(line)
This will automatically close the file as well.

You can easily add a drop-shadow effect to an svg-element using the drop-shadow() CSS function and rgba color values. By using rgba color values you can change the opacity of your shadow.

Sorry for ugly formatting. Just put a question character after declaration and everything will be ok. A question tells the compiler that the value is optional.
class Square: Shape {
var sideLength: Double? // <=== like this ..
init(sideLength:Double, name:String) {
super.init(name:name) // Error here
self.sideLength = sideLength
numberOfSides = 4
}
func area () -> Double {
return sideLength * sideLength
}
}
Edit1:
There is a better way to skip this error. According to jmaschad's comment there is no reason to use optional in your case cause optionals are not comfortable in use and You always have to check if optional is not nil before accessing it. So all you have to do is to initialize member after declaration:
class Square: Shape {
var sideLength: Double=Double()
init(sideLength:Double, name:String) {
super.init(name:name)
self.sideLength = sideLength
numberOfSides = 4
}
func area () -> Double {
return sideLength * sideLength
}
}
Edit2:
After two minuses got on this answer I found even better way. If you want class member to be initialized in your constructor you must assign initial value to it inside contructor and before super.init() call. Like this:
class Square: Shape {
var sideLength: Double
init(sideLength:Double, name:String) {
self.sideLength = sideLength // <= before super.init call..
super.init(name:name)
numberOfSides = 4
}
func area () -> Double {
return sideLength * sideLength
}
}
Good luck in learning Swift.
Some of the other answers are useless because as soon as you re-import the IntelliJ IDEA project from the maven project, all changes will be lost.
The building of the jar needs to be triggered by a run/debug configuration, not by the project settings.
Jetbrains has a nice description of how you can accomplish this here:
https://www.jetbrains.com/help/idea/maven.html
Scroll down to the section called "Configuring triggers for Maven goals".
(The only disadvantage of their description is that their screenshots are in the default black-on-white color scheme instead of the super-awesome darcula theme. Ugh!)
So, basically, what you do is that you open the "Maven Projects" panel, you find the project of interest, (in your case, the project that builds your jar,) underneath it you find the maven goal that you want to execute, (usually the "package" goal creates jars,) you open up the context menu on it, (right-click on a Windows machine,) and there will be an "Execute before Run/Debug..." option that you can select and it will take you by the hand from there. Really easy.

to allow only numbers, for example:
<input type="text" ng-only-number data-max-length=5>
When I find myself thinking about using Manager
or Helper
in a class name, I consider it a code smell that means I haven't found the right abstraction yet and/or I'm violating the single responsibility principle, so refactoring and putting more effort into design often makes naming much easier.
But even well-designed classes don't (always) name themselves, and your choices partly depend on whether you're creating business model classes or technical infrastructure classes.
Business model classes can be hard, because they're different for every domain. There are some terms I use a lot, like Policy
for strategy classes within a domain (e.g., LateRentalPolicy
), but these usually flow from trying to create a "ubiquitous language" that you can share with business users, designing and naming classes so they model real-world ideas, objects, actions, and events.
Technical infrastructure classes are a bit easier, because they describe domains we know really well. I prefer to incorporate design pattern names into the class names, like InsertUserCommand,
CustomerRepository,
or SapAdapter.
I understand the concern about communicating implementation instead of intent, but design patterns marry these two aspects of class design - at least when you're dealing with infrastructure, where you want the implementation design to be transparent even while you're hiding the details.
When you run the Windows Command Prompt, and type in python
, it starts the Python interpreter.
Typing it again tries to interpret python
as a variable, which doesn't exist and thus won't work:
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\USER>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> python
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'python' is not defined
>>> print("interpreter has started")
interpreter has started
>>> quit() # leave the interpreter, and go back to the command line
C:\Users\USER>
If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python
is interpreted as a variable, which you have not defined.
Here's another option. It works by putting an ActiveX ComboBox on top of the cell with validation enabled, and then providing autocomplete in the ComboBox instead.

I don't Know you use any Bootstrap version but the useful helper class for centering and block an element in center it is .center-block
because this class contain margin
and display
CSS properties but the .text-center
class only contain the text-align
property
Depending on your project, you might want to consider using EditorConfig (https://editorconfig.org/). There's a Notepad++ plugin which will load an .editorconfig where you can specify "lf" as the mandatory line ending.
I've only started using it, but it's nice so far, and open source projects I've worked on have included .editorconfig files for years. The "EOL Conversion" setting isn't changed, so it can be a bit confusing, but if you "View > Show Symbol > Show End of Line", you can see that it's adding LF instead of CRLF, even when "EOL Conversion" and the lower bottom corner shows something else (e.g. Windows (CR LF)).
The only way to retrieve the correct value in your context is to run $.ajax()
function synchronously (what actually contradicts to main AJAX idea). There is the special configuration attribute async
you should set to false
. In that case the main scope which actually contains $.ajax()
function call is paused until the synchronous function is done, so, the return
is called only after $.ajax()
.
function doSomething() {
var status = 0;
$.ajax({
url: 'action.php',
type: 'POST',
data: dataString,
async: false,
success: function (txtBack) {
if (txtBack == 1)
status = 1;
}
});
return status;
}
var response = doSomething();
If your function resides in an mvc controller u can use the below code with a dictionary object of what you want to convert to json
Json(someDictionaryObj, JsonRequestBehavior.AllowGet);
Also try and look at system.web.script.serialization.javascriptserializer if you are using .net 3.5
as for your web request...it seems ok at first glance..
I would use something like this..
public void WebRequestinJson(string url, string postData)
{
StreamWriter requestWriter;
var webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;
webRequest.ContentType = "application/json";
//POST the data.
using (requestWriter = new StreamWriter(webRequest.GetRequestStream()))
{
requestWriter.Write(postData);
}
}
}
May be you can make the post and json string a parameter and use this as a generic webrequest method for all calls.
You can do it using the foreach loop
DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];
foreach(DataRow row in dr_art_line_2.Rows)
{
QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
}
Can also try.
_lstProductDetail.Where(S => S.ProductID == "")
.Select(S => { S.ProductPcs = "Update Value" ; return S; }).ToList();
To accomodate all three points:
The file dialog is a setting in the browser.
For the button/save part assign the following function, boiled down from other answers, to your buttons onclick:
function DownloadCanvasAsImage(){
let downloadLink = document.createElement('a');
downloadLink.setAttribute('download', 'CanvasAsImage.png');
let canvas = document.getElementById('myCanvas');
let dataURL = canvas.toDataURL('image/png');
let url = dataURL.replace(/^data:image\/png/,'data:application/octet-stream');
downloadLink.setAttribute('href', url);
downloadLink.click();
}
Another, somewhat cleaner, approach is using Canvas.toBlob():
function DownloadCanvasAsImage(){
let downloadLink = document.createElement('a');
downloadLink.setAttribute('download', 'CanvasAsImage.png');
let canvas = document.getElementById('myCanvas');
canvas.toBlob(function(blob) {
let url = URL.createObjectURL(blob);
downloadLink.setAttribute('href', url);
downloadLink.click();
});
}
Neither solution is 100% cross browser compatible, so check the client
task mathOnProperties << {
println Integer.parseInt(a)+Integer.parseInt(b)
println new Integer(a) * new Integer(b)
}

I think you need str.contains
, if you need rows where values of column date
contains string 07311954
:
print df[df['date'].astype(str).str.contains('07311954')]
Or if type
of date
column is string
:
print df[df['date'].str.contains('07311954')]
If you want check last 4 digits for string
1954
in column date
:
print df[df['date'].astype(str).str[-4:].str.contains('1954')]
Sample:
print df['date']
0 8152007
1 9262007
2 7311954
3 2252011
4 2012011
5 2012011
6 2222011
7 2282011

print df['date'].astype(str).str[-4:].str.contains('1954')

I will suggest to use Object.assign
within a forEach()
loop so that the objects are copied and does not affect the original array of objects
var res = [];
array.forEach(function(item) {
var tempItem = Object.assign({}, item);
delete tempItem.bad;
res.push(tempItem);
});
console.log(res);
Thanks to Don Branson,I solve my problem.I think next time i should use this code when i build my repo on server:
root@localhost:~#mkdir foldername
root@localhost:~#cd foldername
root@localhost:~#git init --bare
root@localhost:~#cd ../
root@localhost:~#chown -R usergroup:username foldername
And on client,i user this
$ git remote add origin git@servername:/var/git/foldername
$ git push origin master
if you have xcopy
, you can use the /E
param, which will copy directories and subdirectories and the files within them, including maintaining the directory structure for empty directories
xcopy [source] [destination] /E
$('input[value="text"]').focus(function(){

You can use DataFrame
constructor with lists
created by to_list
:
import pandas as pd
d1 = {'teams': [['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],
['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG']]}
df2 = pd.DataFrame(d1)
print (df2)
teams
0 [SF, NYG]
1 [SF, NYG]
2 [SF, NYG]
3 [SF, NYG]
4 [SF, NYG]
5 [SF, NYG]
6 [SF, NYG]
df2[['team1','team2']] = pd.DataFrame(df2.teams.tolist(), index= df2.index)
print (df2)
teams team1 team2
0 [SF, NYG] SF NYG
1 [SF, NYG] SF NYG
2 [SF, NYG] SF NYG
3 [SF, NYG] SF NYG
4 [SF, NYG] SF NYG
5 [SF, NYG] SF NYG
6 [SF, NYG] SF NYG
And for new DataFrame
:
df3 = pd.DataFrame(df2['teams'].to_list(), columns=['team1','team2'])
print (df3)
team1 team2
0 SF NYG
1 SF NYG
2 SF NYG
3 SF NYG
4 SF NYG
5 SF NYG
6 SF NYG
Solution with apply(pd.Series)
is very slow:
#7k rows
df2 = pd.concat([df2]*1000).reset_index(drop=True)
In [121]: %timeit df2['teams'].apply(pd.Series)
1.79 s ± 52.5 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
In [122]: %timeit pd.DataFrame(df2['teams'].to_list(), columns=['team1','team2'])
1.63 ms ± 54.3 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
i just had the same problems - have been testing a lot of different stuff. but it just wouldn't work. then i checked the tutorial examples on jQuery.com again and found out:
your jQuery script needs to be after the elements you are referring to !
so your script needs to be after the html-code you want to access!
seems like jQuery can't access it otherwise.
argmax()
will only return the first occurrence for each row.

If you ever need to do this for a shaped array, this works better than unravel
:
import numpy as np
a = np.array([[1,2,3], [4,3,1]]) # Can be of any shape
indices = np.where(a == a.max())
You can also change your conditions:
indices = np.where(a >= 1.5)
The above gives you results in the form that you asked for. Alternatively, you can convert to a list of x,y coordinates by:
x_y_coords = zip(indices[0], indices[1])
If you want to launch from a batch file:
for x86
start "" "%SYSTEMDRIVE%\Program Files (x86)\Git\bin\sh.exe" --login
for x64
start "" "%PROGRAMFILES%\Git\bin\sh.exe" --login

Its very easy to create procedure in Mysql. Here, in my example I am going to create a procedure which is responsible to fetch all data from student table according to supplied name.
DELIMITER //
CREATE PROCEDURE getStudentInfo(IN s_name VARCHAR(64))
BEGIN
SELECT * FROM student_database.student s where s.sname = s_name;
END//
DELIMITER;
In the above example ,database and table names are student_database and student respectively. Note: Instead of s_name, you can also pass @s_name as global variable.
How to call procedure? Well! its very easy, simply you can call procedure by hitting this command
$mysql> CAll getStudentInfo('pass_required_name');
ffmpeg -codecs
should give you all the info about the codecs available.
You will see some letters next to the codecs:
Codecs:
D..... = Decoding supported
.E.... = Encoding supported
..V... = Video codec
..A... = Audio codec
..S... = Subtitle codec
...I.. = Intra frame-only codec
....L. = Lossy compression
.....S = Lossless compression
Avoid converting the table object directly. If relations are set between other tables, it might throw this error. Rather, you can create a model class, assign values to the class object and then serialize it.
Little side note for anyone new to Python who didn't figure it out by theirself: this should be automatic when installing Python, but just in case, note that to run Python using the python
command in Windows' CMD you must first add it to the PATH
environment variable, as explained here.
To execute Pip, first of all make sure you have it installed, so type in your CMD:
> python
>>> import pip
>>>
And it should proceed with no error. Otherwise, if this fails, you can look here to see how to install it. Now that you are sure you've got Pip, you can run it from CMD with Python using the -m
(module) parameter, like this:
> python -m pip <command> <args>
Where <command>
is any Pip command you want to run, and <args>
are its relative arguments, separated by spaces.
For example, to install a package:
> python -m pip install <package-name>
Your code: path = ActiveWorkbook.Path
returns blank because you haven't saved your workbook yet.
To overcome your problem, go back to the Excel sheet, save your sheet, and run your code again.
This time it will not show blank, but will show you the path where it is located (current folder)
I hope that helped.
There is another way of doing this with just JavaScript. All you have to do is toggle the visibility based on the current state of the DIV's visibility in CSS.
Example:
function toggleVideo() {
var e = document.getElementById('video-over');
if(e.style.visibility == 'visible') {
e.style.visibility = 'hidden';
} else if(e.style.visibility == 'hidden') {
e.style.visibility = 'visible';
}
}
Your initial page is a complete HTML page containing a form, the contents of which are posted to insert.php when the submit button is clicked, but insert.php needs to process the form's contents and do something with them, like add them to a database, or output them to a new page. Your current insert.php just outputs the contents of the title field, so your browser tries to interpret that as an HTML page, and fails, obviously, because it isn't valid HTML (i.e. it isn't contained in an 'HTML' tag, etc.).
Your insert.php needs to output the necessary HTML, and insert the form data in there somewhere.
For example:
<?php
$title = $_POST["title"];
$price = $_POST["price"];
echo '<html xmlns="http://www.w3.org/1999/xhtml">';
echo '<head>';
echo '<meta http-equiv="content-type" content="text/html; charset=utf-8" />';
echo '<title>';
echo $title;
echo '</title>';
echo '</head>';
echo '<body>';
echo 'Hello, world.';
echo '</body>';
?>
On Linux, you can read the /proc/cpuinfo file and count the cores.
I'm completely revising my original answer because of points raised in the other questions and comments. Here is the new benchmark script:
import time
import numpy as np
def fancy_index_relu(m):
m[m < 0] = 0
relus = {
"max": lambda x: np.maximum(x, 0),
"in-place max": lambda x: np.maximum(x, 0, x),
"mul": lambda x: x * (x > 0),
"abs": lambda x: (abs(x) + x) / 2,
"fancy index": fancy_index_relu,
}
for name, relu in relus.items():
n_iter = 20
x = np.random.random((n_iter, 5000, 5000)) - 0.5
t1 = time.time()
for i in range(n_iter):
relu(x[i])
t2 = time.time()
print("{:>12s} {:3.0f} ms".format(name, (t2 - t1) / n_iter * 1000))
It takes care to use a different ndarray for each implementation and iteration. Here are the results:
max 126 ms
in-place max 107 ms
mul 136 ms
abs 86 ms
fancy index 132 ms
SHOW KEYS FROM tablename WHERE Key_name='unique key name'
you can find if there exists an unique key in the table
On macOS with the default python installation you need to add /Users/<you>/Library/Python/2.7/bin/
to your $PATH.
Add this to your .bash_profile:
export PATH="/Users/<you>/Library/Python/2.7/bin:$PATH"
That's where pip installs the executables.
Tip: For non-default python version which python
to find the location of your python installation and replace that portion in the path above. (Thanks for the hint Sanket_Diwale)
You could find disk intensive full table scans with something like this:

ORDER BY DISK_READS * EXECUTIONS DESC
)
WHERE KeepHighSQL = 1
AND rownum <=5;

Symlinked directories:
It's important to note what happens when there is a directory which is a soft link. Any Git pull with an update removes the link and makes it a normal directory. This is what I learnt hard way. Some insights here and here.
Example
Before
ls -l
lrwxrwxrwx 1 admin adm 29 Sep 30 15:28 src/somedir -> /mnt/somedir
git add/commit/push
It remains the same
After git pull
AND some updates found
drwxrwsr-x 2 admin adm 4096 Oct 2 05:54 src/somedir
Try
$(this).removeAttr('checked')
Since a lot of browsers will interpret 'checked=anything' as true. This will remove the checked attribute altogether.
Hope this helps.
Quick tip
For a strongly typed Model just add it to the ViewData.Model property before passing to RenderViewToString. e.g
this.ViewData.Model = new OrderResultEmailViewModel(order);
string myString = RenderViewToString(this.ControllerContext, "~/Views/Order/OrderResultEmail.aspx", "~/Views/Shared/Site.Master", this.ViewData, this.TempData);
Strings in C are represented as arrays of characters.
char *p = "String";
You are declaring a pointer that points to a string stored some where in your program (modifying this string is undefined behavior) according to the C programming language 2 ed.
char p2[] = "String";
You are declaring an array of char initialized with the string "String" leaving to the compiler the job to count the size of the array.
char p3[5] = "String";
You are declaring an array of size 5 and initializing it with "String". This is an error be cause "String" don't fit in 5 elements.
char p3[7] = "String";
is the correct declaration ('\0' is the terminating character in c strings).
Move your javascript into a function and then bind that function to window resize.
$(document).ready(function () {
updateContainer();
$(window).resize(function() {
updateContainer();
});
});
function updateContainer() {
var $containerHeight = $(window).height();
if ($containerHeight <= 818) {
$('.footer').css({
position: 'static',
bottom: 'auto',
left: 'auto'
});
}
if ($containerHeight > 819) {
$('.footer').css({
position: 'absolute',
bottom: '3px',
left: '0px'
});
}
}
here is an answer working with:
float('nan')
, numpy.nan
...A NaN implemented following the standard, is the only value for which the inequality comparison with itself should return True:
def is_nan(x):
return (x != x)
And some examples:
import numpy as np
values = [float('nan'), np.nan, 55, "string", lambda x : x]
for value in values:
print(f"{repr(value):<8} : {is_nan(value)}")
Output:
nan : True
nan : True
55 : False
'string' : False

Activity
class is the basic class. (The original) It supports Fragment management (Since API 11). Is not recommended anymore its pure use because its specializations are far better.
ActionBarActivity
was in a moment the replacement to the Activity class because it made easy to handle the ActionBar in an app.
AppCompatActivity
is the new way to go because the ActionBar is not encouraged anymore and you should use Toolbar instead (that's currently the ActionBar replacement). AppCompatActivity inherits from FragmentActivity so if you need to handle Fragments you can (via the Fragment Manager). AppCompatActivity is for ANY API, not only 16+ (who said that?). You can use it by adding compile 'com.android.support:appcompat-v7:24:2.0'
in your Gradle file. I use it in API 10 and it works perfect.
Check out the library angular-cache if you like $http's built-in caching but want more control. You can use it to seamlessly augment $http cache with time-to-live, periodic purges, and the option of persisting the cache to localStorage so that it's available across sessions.
FWIW, it also provides tools and patterns for making your cache into a more dynamic sort of data-store that you can interact with as POJO's, rather than just the default JSON strings. Can't comment on the utility of that option as yet.
(Then, on top of that, related library angular-data is sort of a replacement for $resource and/or Restangular, and is dependent upon angular-cache.)
Huffman coding generally works okay for this.
Use .net 4 BlockingCollection, to enqueue use Add(), to dequeue use Take(). It internally uses non-blocking ConcurrentQueue. More info here Fast and Best Producer/consumer queue technique BlockingCollection vs concurrent Queue
It's a common misconception that you can denormalise like this for performance. Use date_trunc('month', date)
for your queries and add an index expression for this if you find it running slow.
Construct both separate queries and joins, then time each of them -- nothing helps more than real-world numbers.
Then even better -- add "EXPLAIN" to the beginning of each query. This will tell you how many subqueries MySQL is using to answer your request for data, and how many rows scanned for each query.
SimpleDateFormat.format()
method takes a Date
as a parameter. You can get a Date
from a Calendar
by calling its getTime()
method:
public static String format(GregorianCalendar calendar) {
SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
fmt.setCalendar(calendar);
String dateFormatted = fmt.format(calendar.getTime());
return dateFormatted;
}
Also note that the months start at 0, so you probably meant:
int month = Integer.parseInt(splitDate[1]) - 1;
If you don't want the hassle of using mail
, you can read the mail with
cat /var/mail/<username>
and delete the mail with
sudo rm /var/mail/<username>
$(document).ready(function(){_x000D_
$('input').on("cut copy paste",function(e) {_x000D_

Found another solution:
For a quick solution, I usually do like this.
This approach will allow the user to enter date in any format they like in the textbox, and finally format in mm/dd/yyyy format when he is done editing. So it is quite flexible:
Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
If TextBox1.Text <> "" Then
If IsDate(TextBox1.Text) Then
TextBox1.Text = Format(TextBox1.Text, "mm/dd/yyyy")
Else
MsgBox "Please enter a valid date!"
Cancel = True
End If
End If
End Sub
However, I think what Sid developed is a much better approach - a full fledged date picker control.
What worked to me was to use the REPOSITORY:TAG combination rather than IMAGE ID.
When I tried to delete a docker image with the command docker rmi <IMAGE ID>
with no containers associated with this image I had the message:
$ docker rmi 3f66bec2c6bf
Error response from daemon: conflict: unable to delete 3f66bec2c6bf (cannot be forced) - image has dependent child images
I could delete with success when I used the command docker rmi RPOSITORY:TAG
$ docker rmi ubuntu:18.04v1
Untagged: ubuntu:18.04v1
Aaron's approach above worked perfectly for me. My update statement was slightly different because I needed to join based on two fields concatenated in one table to match a field in another table.
--update clients table cell field from custom table containing mobile numbers
update clients
set cell = m.Phone
from clients as c
inner join [dbo].[COSStaffMobileNumbers] as m
on c.Last_Name + c.First_Name = m.Name
JSON parsing using NSJSONSerialization
NSString* path = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"json"];
//Here you can take JSON string from your URL ,I am using json file
NSString* jsonString = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
NSData* jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *jsonError;
NSArray *jsonDataArray = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&jsonError];
NSLog(@"jsonDataArray: %@",jsonDataArray);
NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&jsonError];
if(jsonObject !=nil){
// NSString *errorCode=[NSMutableString stringWithFormat:@"%@",[jsonObject objectForKey:@"response"]];
if(![[jsonObject objectForKey:@"#data"] isEqual:@""]){
NSMutableArray *array=[jsonObject objectForKey:@"#data"];
// NSLog(@"array: %@",array);
NSLog(@"array: %d",array.count);
int k = 0;
for(int z = 0; z<array.count;z++){
NSString *strfd = [NSString stringWithFormat:@"%d",k];
NSDictionary *dicr = jsonObject[@"#data"][strfd];
k=k+1;
// NSLog(@"dicr: %@",dicr);
NSLog(@"Firstname - Lastname : %@ - %@",
[NSMutableString stringWithFormat:@"%@",[dicr objectForKey:@"user_first_name"]],
[NSMutableString stringWithFormat:@"%@",[dicr objectForKey:@"user_last_name"]]);
}
}
}
You can see the Console output as below :
Firstname - Lastname : Chandra Bhusan - Pandey
Firstname - Lastname : Kalaiyarasan - Balu
Firstname - Lastname : (null) - (null)
Firstname - Lastname : Girija - S
Firstname - Lastname : Girija - S
Firstname - Lastname : (null) - (null)

As a late corolloary to the earlier answers here, you probably end up in situations where you want some but not all variables to be interpolated. You can solve that by using backslashes to escape dollar signs and backticks; or you can put the static text in a variable.
Name='Rich Ba$tard'
dough='$$$dollars$$$'
cat <<____HERE
$Name, you can win a lot of $dough this week!
Notice that \`backticks' need escaping if you want
literal text, not `pwd`, just like in variables like
\$HOME (current value: $HOME)
____HERE
Demo: https://ideone.com/rMF2XA
Note that any of the quoting mechanisms -- \____HERE
or "____HERE"
or '____HERE'
-- will disable all variable interpolation, and turn the here-document into a piece of literal text.
A common task is to combine local variables with script which should be evaluated by a different shell, programming language, or remote host.
local=$(uname)
ssh -t remote <<:
echo "$local is the value from the host which ran the ssh command"
# Prevent here doc from expanding locally; remote won't see backslash
remote=\$(uname)
# Same here
echo "\$remote is the value from the host we ssh:ed to"

used ast, example
In [15]: a = "[{'start_city': '1', 'end_city': 'aaa', 'number': 1},\
...: {'start_city': '2', 'end_city': 'bbb', 'number': 1},\
...: {'start_city': '3', 'end_city': 'ccc', 'number': 1}]"
In [16]: import ast
In [17]: ast.literal_eval(a)
Out[17]:
[{'end_city': 'aaa', 'number': 1, 'start_city': '1'},
{'end_city': 'bbb', 'number': 1, 'start_city': '2'},
{'end_city': 'ccc', 'number': 1, 'start_city': '3'}]
It's simple, use $.getJSON()
function and in your URL just include
callback=?
as a parameter. That will convert the call to JSONP which is necessary to make cross-domain calls. More info: http://api.jquery.com/jQuery.getJSON/
In my case, my server was configured to work only in https mode, and error occured when I try to access http mode. So changing http://my-service
to https://my-service
helped.
You should keep a watch on your scope.
Here is how you can do it:
<layout layoutId="myScope"></layout>
Your directive should look like
app.directive('layout', function($http, $compile){
return {
restrict: 'E',
scope: {
layoutId: "=layoutId"
},
link: function(scope, element, attributes) {
var layoutName = (angular.isDefined(attributes.name)) ? attributes.name : 'Default';
$http.get(scope.constants.pathLayouts + layoutName + '.html')
.success(function(layout){
var regexp = /^([\s\S]*?){{content}}([\s\S]*)$/g;
var result = regexp.exec(layout);
var templateWithLayout = result[1] + element.html() + result[2];
element.html($compile(templateWithLayout)(scope));
});
}
}
$scope.$watch('myScope',function(){
//Do Whatever you want
},true)
Similarly you can models in your directive, so if model updates automatically your watch method will update your directive.
For me, this used to work, but upgrading libraries caused this issue to appear. Problem was having a class like this:
package example.counter;
import javax.validation.constraints.NotNull;
import lombok.Data;
@Data
public class CounterRequest {
@NotNull
private final Integer int1;
@NotNull
private final Integer int2;
}
Using lombok:
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.0</version>
</dependency>
Falling back to
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.10</version>
</dependency>
Fixed the issue. Not sure why, but wanted to document it for future.
I implemented Marcus Ekwall's solution but was able to remove a few things to make it simpler and it still works. Maybe 2017 version of html/css?

<h2>What is Lorem Ipsum?</h2>
<p><strong>Lorem Ipsum</strong> is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen
book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with
desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
