While loop will take long time to delete all items if array has 100's of items. You can empty both controls and value properties of FormArray like below.
clearFormArray = (formArray: FormArray) => { formArray.controls = []; formArray.setValue([]); }
I also had problem with proximity sensor (I shattered screen in that region on my Nexus 6, Android Marshmallow) and none of proposed solutions / third party apps worked when I tried to disable proximity sensor. What worked for me was to calibrate the sensor using Proximity Sensor Reset/Repair. You have to follow the instruction in app (cover sensor and uncover it) and then restart your phone. Although my sensor is no longer behind the glass, it still showed slightly different results when covered / uncovered and recalibration did the job.
What I tried and didn't work? Proximity Screen Off Lite, Macrodroid and KinScreen.
What would've I tried had it still not worked?[XPOSED] Sensor Disabler, but it requires you to be rooted and have Xposed Framework, so I'm really glad I've found the easier way.
A .tex file should be a LaTeX source file.
If this is the case, that file contains the source code for a LaTeX document. You can open it with any text editor (notepad, notepad++ should work) and you can view the source code. But if you want to view the final formatted document, you need to install a LaTeX distribution and compile the .tex file.
Of course, any program can write any file with any extension, so if this is not a LaTeX document, then we can't know what software you need to install to open it. Maybe if you upload the file somewhere and link it in your question we can see the file and provide more help to you.
Yes, this is the source code of a LaTeX document. If you were able to paste it here, then you are already viewing it. If you want to view the compiled document, you need to install a LaTeX distribution. You can try to install MiKTeX then you can use that to compile the document to a .pdf file.
You can also check out this question and answer for how to do it: How to compile a LaTeX document?
Also, there's an online LaTeX editor and you can paste your code in there to preview the document: https://www.overleaf.com/.

Some Linux based MySQL installations require case sensitive. Work around is to apply nativeQuery

While reading the TCP UDP debate I noticed a logical flaw. A TCP packet loss causing a one minute delay that's converted into a one minute buffer cant be correlated to UDP dropping a full minute while experiencing the same loss. A more fair comparison is as follows.
TCP experiences a packet loss. The video is stopped while TCP resend's packets in an attempt to stream mathematically perfect packets. Video is delayed for one minute and picks up where it left off after missing packet makes its destination. We all wait but we know we wont miss a single pixel.
UDP experiences a packet loss. For a second during the video stream a corner of the screen gets a little blurry. No one notices and the show goes on without looking for the lost packets.
Anything that streams gains the most benefits from UDP. The packet loss causing a one minute delay to TCP would not cause a one minute delay to UDP. Considering that most systems use multiple resolution streams making things go blocky when starving for packets, makes even more sense to use UDP.
UDP FTW when streaming.
.NET can do it with its System.Speech namespace.

I'm assuming you mean that you want to run your own private video calls, not simply link to Skype calls or similar. You really have 2 options here: host it yourself, or use a hosted solution and integrate it into your product.
Self-Hosted ----------------- This is messy. This can all be accomplished with PHP, but that is probably not the most advisable solution, as it is not the best tool for the job on all sides. Flash is much more efficient at a/v capture and transport on the user end. You can try to do this without flash, but you will have headaches. HTML5 may make your life easier, but if you're shooting for maximum compatibility, flash is the simplest way to go for creating the client. Then, as far as the actual server side that will relay the audio/video, you could write a chat server in php, but you're better off using an open source project, like janenz00's mention of red5, that's already built and interfacing with it through your client (if it doesn't already have one). Or you could homebrew a flash client as mentioned before and hook it up to a flash streaming server on both sides...either way it gets complicated fast, and is beyond my expertise to help you with at all.
Hosted Service ----------------- All in, my recommendation, unless you want to administer a ridiculous setup of many complex servers and failure points is to use a hosted service like UserPlane or similar and offload all the processing and technical work to people who are good at that, and then worry about interfacing with their api and getting their client well integrated into your site. You will be a happier developer if you do.
Converting VARCHAR2 to CLOB
In PL/SQL a CLOB can be converted to a VARCHAR2 with a simple assignment, SUBSTR, and other methods. A simple assignment will only work if the CLOB is less then or equal to the size of the VARCHAR2. The limit is 32767 in PL/SQL and 4000 in SQL (although 12c allows 32767 in SQL).
For example, this code converts a small CLOB through a simple assignment and then coverts the beginning of a larger CLOB.
declare
v_small_clob clob := lpad('0', 1000, '0');
v_large_clob clob := lpad('0', 32767, '0') || lpad('0', 32767, '0');
v_varchar2 varchar2(32767);
begin
v_varchar2 := v_small_clob;
v_varchar2 := substr(v_large_clob, 1, 32767);
end;
LONG?
The above code does not convert the value to a LONG. It merely looks that way because of limitations with PL/SQL debuggers and strings over 999 characters long.
For example, in PL/SQL Developer, open a Test window and add and debug the above code. Right-click on v_varchar2
and select "Add variable to Watches". Step through the code and the value will be set to "(Long Value)". There is a ...
next to the text but it does not display the contents.
C#?
I suspect the real problem here is with C# but I don't know how enough about C# to debug the problem.
You don't really need to do any of this.

The problem you encountered is due to this:
A block is a piece of Python program text that is executed as a unit. The following are blocks: a module, a function body, and a class definition.
(...)
A scope defines the visibility of a name within a block.
(...)
The scope of names defined in a class block is limited to the class block; it does not extend to the code blocks of methods – this includes generator expressions since they are implemented using a function scope. This means that the following will fail:class A: a = 42 b = list(a + i for i in range(10))
http://docs.python.org/reference/executionmodel.html#naming-and-binding
The above means:
a function body is a code block and a method is a function, then names defined out of the function body present in a class definition do not extend to the function body.
Paraphrasing this for your case:
a class definition is a code block, then names defined out of the inner class definition present in an outer class definition do not extend to the inner class definition.

A class in HTML means that in order to set attributes to it in CSS, you simply need to add a period in front of it.
For example, the CSS code of that html code may be:
.clear { height: 50px; width: 25px; }
Also, if you, as suggested by abiessu, are attempting to add the CSS clear: both;
attribute to the div to prevent anything from floating to the left or right of this div, you can use this CSS code:
.clear { clear: both; }
Here's a way to convert binary numbers to ASCII characters that is often simple enough to do in your head.
1 - Convert every 4 binary digits into one hex digit.
Here's a binary to hex conversion chart:
0001 = 1
0010 = 2
0011 = 3
0100 = 4
0101 = 5
0110 = 6
0111 = 7
1000 = 8
1001 = 9
1010 = a (the hex number a, not the letter a)
1011 = b
1100 = c
1101 = d
1110 = e
1111 = f
(The hexadecimal numbers a through f are the decimal numbers 10 through 15. That's what hexadecimal, or "base 16" is - instead of each digit being capable of representing 10 different numbers [0 - 9], like decimal or "base 10" does, each digit is instead capable of representing 16 different numbers [0 - f].)
Once you know that chart, converting any string of binary digits into a string of hex digits is simple.
For example,
01000100 = 0100 0100 = 44 hex
1010001001110011 = 1010 0010 0111 0011 = a273 hex
Simple enough, right? It is a simple matter to convert a binary number of any length into its hexadecimal equivalent.
(This works because hexadecimal is base 16 and binary is base 2 and 16 is the 4th power of 2, so it takes 4 binary digits to make 1 hex digit. 10, on the other hand, is not a power of 2, so we can't convert binary to decimal nearly as easily.)
2 - Split the string of hex digits into pairs.
When converting a number into ASCII, every 2 hex digits is a character. So break the hex string into sets of 2 digits.
You would split a hex number like 7340298b392 this into 6 pairs, like this:
7340298b392 = 07 34 02 98 b3 92
(Notice I prepended a 0, since I had an odd number of hex digits.)
That's 6 pairs of hex digits, so its going to be 6 letters. (Except I know right away that 98, b3 and 92 aren't letters. I'll explain why in a minute.)
3 - Convert each pair of hex digits into a decimal number.
Do this by multiplying the (decimal equivalent of the) left digit by 16, and adding the 2nd.
For example, b3 hex = 11*16 + 3, which is 110 + 66 + 3, which is 179. (b hex is 11 decimal.)
4 - Convert the decimal numbers into ASCII characters.
Now, to get the ASCII letters for the decimal numbers, simply keep in mind that in ASCII, 65 is an uppercase 'A', and 97 is a lowercase 'a'.
So what letter is 68?
68 is the 4th letter of the alphabet in uppercase, right?
65 = A, 66 = B, 67 = C, 68 = D.
So 68 is 'D'.
You take the decimal number, subtract 64 for uppercase letters if the number is less than 97, or 96 for lowercase letters if the number is 97 or larger, and that's the number of the letter of the alphabet associated with that set of 2 hex digits.
Alternatively, if you're not afraid of a little bit of easy hex arithmetic, you can skip step 3, and just go straight from hex to ASCII, by remembering, for example, that
hex 41 = 'A'
hex 61 = 'a'
So subtract 40 hex for uppercase letters or 60 hex for lowercase letters, and convert what's left to decimal to get the alphabet letter number.
For example
01101100 = 6c, 6c - 60 = c = 12 decimal = 'l'
01010010 = 52, 52 - 40 = 12 hex = 18 decimal = 'R'
(When doing this, it's helpful to remember that 'm' (or 'M') is the 13 letter of the alphabet. So you can count up or down from 13 to find a letter that's nearer to the middle than to either end.)
I saw this on a shirt once, and was able to read it in my head:
01000100
01000001
01000100
I did it like this:
01000100 = 0100 0100 = 44 hex, - 40 hex = ucase letter 4 = D
01000001 = 0100 0001 = 41 hex, - 40 hex = ucase letter 1 = A
01000100 = 0100 0100 = 44 hex, - 40 hex = ucase letter 4 = D
The shirt said "DAD", which I thought was kinda cool, since it was being purchased by a pregnant woman. Her husband must be a geek like me.
How did I know right away that 92, b3, and 98 were not letters?
Because the ASCII code for a lowercase 'z' is 96 + 26 = 122, which in hex is 7a. 7a is the largest hex number for a letter. Anything larger than 7a is not a letter.
So that's how you can do it as a human.
How do computer programs do it?
For each set of 8 binary digits, convert it to a number, and look it up in an ASCII table.
(That's one pretty obvious and straight forward way. A typical programmer could probably think of 10 or 15 other ways in the space of a few minutes. The details depend on the computer language environment.)
The truth is, you can't force the browser to ask. I'm sure the browser has it's own algorithm for guessing if you've entered a username/password, such as looking for an input of type="password"
but you cannot set anything to force the browser.
You could, as others suggest, add user information in a cookie. If you do this, you better encrypt it at the least and do not store their password. Perhaps store their username at most.
ORA-01861: literal does not match format string
This happens because you have tried to enter a literal with a format string, but the length of the format string was not the same length as the literal.
You can overcome this issue by carrying out following alteration.
TO_DATE('1989-12-09','YYYY-MM-DD')
As a general rule, if you are using the TO_DATE function, TO_TIMESTAMP function, TO_CHAR function, and similar functions, make sure that the literal that you provide matches the format string that you've specified
At last I fixed it simply using:
display: table;
I found a work around. Python will convert the number to a float. Simply calling float first then converting that to an int will work:
output = int(float(input))
If you're in a situation where you don't have control over whether part of the condition is checking a nullable value, you can always try the following:
if( someInt == 6 && someNullableBool == null ? false : (bool)someNullableBool){
//perform your actions if true
}
I know it's not exactly a purist approach putting a ternary in an if statement but it does resolve the issue cleanly.
This is, of course, a manual way of saying GetValueOrDefault(false)
private boolean isAppExist() {
PackageManager pm = getPackageManager();
try {
PackageInfo info = pm.getPackageInfo("com.facebook.katana", PackageManager.GET_META_DATA);
} catch (PackageManager.NameNotFoundException e) {
return false;
}
return true;
}
if (isFacebookExist()) {showToast(" Facebook is install.");}
else {showToast(" Facebook is not install.");}
It is printing twice because you are calling printf twice, once in the execution of your program and once in the fork. Try taking your fork() out of the printf call.
I would like to update on this, because in .NET Core multi-dimensional arrays are faster than jagged arrays. I ran the tests from John Leidegren and these are the results on .NET Core 2.0 preview 2. I increased the dimension value to make any possible influences from background apps less visible.

single[i * dim * dim + j * dim + k] = i * j * k;

I wasn't able to identify why single-dimensional arrays were still faster than multi-dimensional but my guess is that it has to do with some optimalization made on the CPU
You can use the annotate command to place text annotations at any x and y values you want. To place them exactly at the data points you could do this
import numpy
from matplotlib import pyplot
x = numpy.arange(10)
y = numpy.array([5,3,4,2,7,5,4,6,3,2])
fig = pyplot.figure()
ax = fig.add_subplot(111)
ax.set_ylim(0,10)
pyplot.plot(x,y)
for i,j in zip(x,y):
ax.annotate(str(j),xy=(i,j))
pyplot.show()
If you want the annotations offset a little, you could change the annotate
line to something like
ax.annotate(str(j),xy=(i,j+0.5))
Try the following:
public static Stream ToStream(this Image image, ImageFormat format) {
var stream = new System.IO.MemoryStream();
image.Save(stream, format);
stream.Position = 0;
return stream;
}
Then you can use the following:
var stream = myImage.ToStream(ImageFormat.Gif);
Replace GIF with whatever format is appropriate for your scenario.
Change your onCreate to
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
for me this update worked
def x(a):
print(a)
return a
def y(func_to_run, a):
return func_to_run(a)
y(x, 1)
That I think would be a more proper sample. Now what I wonder is if there is a way to code the function to use within the argument submission to another function. I believe there is in C++, but in Python I am not sure.
Documentation can be found e.g. at MDN. Note that .split()
is not a jQuery method, but a native string method.
If you use .split()
on a string, then you get an array back with the substrings:
var str = 'something -- something_else';
var substr = str.split(' -- ');
// substr[0] contains "something"
// substr[1] contains "something_else"
If this value is in some field you could also do:
tRow.append($('<td>').text($('[id$=txtEntry2]').val().split(' -- ')[0])));
The Error is here
lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1
wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this
lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1
Similarly
wsPOR.Range("A2:G" & lastrow).Select
should be
wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select
I hit an issue where following an Update, SVN showed a folder as being conflicted. Strangely, this was only visible through the command line - TortoiseSVN thought it was all fine.
#>svn st
! my_dir
! my_dir\sub_dir
svn cleanup
, svn revert
, svn update
and svn resolve
were all unsuccessful at fixing this.
I eventually solved the problem as follows:
Following that, everything was fine.
Note I didn't have any local changes, so I don't know if you'd be at risk if you did. I didn't use the delete / update method suggested by others - I got into this state by trying that on the my_dir/sub_dir/sub_sub_dir directory (which started with the same symptoms) - so I didn't want to risk making things worse again!
Not quite on-topic, but maybe helpful if someone comes across this post as I did.
Depending on how it will be used, you can either do this with two maps Map<K1, V>
and Map<K2, V>
or with two maps Map<K1, V>
and Map<K2, K1>
. If one of the keys is more permanent than the other, the second option may make more sense.
Here are three ways to parse strings into integers, from fastest runtime to slowest:
strconv.ParseInt(...)
fasteststrconv.Atoi(...)
still very fastfmt.Sscanf(...)
not terribly fast but most flexibleHere's a benchmark that shows usage and example timing for each function:
package main
import "fmt"
import "strconv"
import "testing"
var num = 123456
var numstr = "123456"
func BenchmarkStrconvParseInt(b *testing.B) {
num64 := int64(num)
for i := 0; i < b.N; i++ {
x, err := strconv.ParseInt(numstr, 10, 64)
if x != num64 || err != nil {
b.Error(err)
}
}
}
func BenchmarkAtoi(b *testing.B) {
for i := 0; i < b.N; i++ {
x, err := strconv.Atoi(numstr)
if x != num || err != nil {
b.Error(err)
}
}
}
func BenchmarkFmtSscan(b *testing.B) {
for i := 0; i < b.N; i++ {
var x int
n, err := fmt.Sscanf(numstr, "%d", &x)
if n != 1 || x != num || err != nil {
b.Error(err)
}
}
}

Do something like this:
A <div>
with ID of #imageDIV
, another one with ID #download
and a hidden <div>
with ID #previewImage
.
Include the latest version of jquery, and jspdf.debug.js from the jspdf CDN
Then add this script:
var element = $("#imageDIV"); // global variable
var getCanvas; // global variable
$('document').ready(function(){
html2canvas(element, {
onrendered: function (canvas) {
$("#previewImage").append(canvas);
getCanvas = canvas;
}
});
});
$("#download").on('click', function () {
var imgageData = getCanvas.toDataURL("image/png");
// Now browser starts downloading it instead of just showing it
var newData = imageData.replace(/^data:image\/png/, "data:application/octet-stream");
$("#download").attr("download", "image.png").attr("href", newData);
});

You need to add an action
into your form like:
<form name='form1' method='post' action='<?php echo($_SERVER['PHP_SELF']);'>
<!-- All your input for the form here -->
</form>
Then put your snippet at the top of the document en send the mail. What echo($_SERVER['PHP_SELF']);
does is that it sends your information to the top of your script so you could use it.
I have updated your jsfiddle and here is CSS changes you need to do:

}
To stop repeated alert of Nick's answer
ScrollActivate();
function ScrollActivate() {
$(window).on("scroll", function () {
if ($(window).scrollTop() + $(window).height() > $(document).height() - 100) {
$(window).off("scroll");
alert("near bottom!");
}
});
}
Or even more simple if you don't want to use a lot of linq and for some reason don't want to use a for loop.
int i = 0;
foreach(var x in arr)
{
//Do some stuff
i++;
}
To position horizontally center you can say width: 50%; margin: auto;
. As far as I know, that's cross browser. For vertical alignment you can try vertical-align:middle;
, but it may only work in relation to text. It's worth a try though.
No, because the commit message is related with the commit SHA / hash, and if we change it the commit SHA is also changed. The way I used is to create a comment on that commit. I can't think the other way.

If you are using VS Code, you can rename the .ts, .html, .css/.scss, .spec.ts
files and the IDE will take care of the imports for you. Therefore there will be no complaints from the files that import files from your component (such as app.module.ts
). However, you will still have to rename the component name everywhere it is being used.

Right click on your class library, and choose the "Add References" option from the Menu.
And from the .NET tab, select System.Configuration. This would include the System.Configuration DLL file into your project.
I spent some time trying to find a nice function to wrap a solution. Anyway, ended up with this which I feel is a better solutions when loading multiple content on a single page or across a site.
Function:
function ifViewLoadContent(elem, LoadContent)
{
var top_of_element = $(elem).offset().top;
var bottom_of_element = $(elem).offset().top + $(elem).outerHeight();
var bottom_of_screen = $(window).scrollTop() + window.innerHeight;
var top_of_screen = $(window).scrollTop();
if((bottom_of_screen > top_of_element) && (top_of_screen < bottom_of_element)){
if(!$(elem).hasClass("ImLoaded")) {
$(elem).load(LoadContent).addClass("ImLoaded");
}
}
else {
return false;
}
}
You can then call the function using window on scroll (for example, you could also bind it to a click etc. as I also do, hence the function):
To use:
$(window).scroll(function (event) {
ifViewLoadContent("#AjaxDivOne", "someFile/somecontent.html");
ifViewLoadContent("#AjaxDivTwo", "someFile/somemorecontent.html");
});
This approach should also work for scrolling divs etc. I hope it helps, in the question above you could use this approach to load your content in sections, maybe append and thereby dribble feed all that image data rather than bulk feed.
I used this approach to reduce the overhead on https://www.taxformcalculator.com. It died the trick, if you look at the site and inspect element etc. you can see impact on page load in Chrome (as an example).
Connect to DB using base user:
mysql -u base_user -pbase_user_pass
And execute CREATE DATABASE, CREATE USER and GRANT PRIVILEGES Statements.
Here's handy web wizard to help you with statements www.bugaco.com/helpers/create_database.html
Params contains the following three groups of parameters:
match '/user/:id'
in routes.rb will set params[:id]params[:controller]
and params[:action]
is always available and contains the current controller and actionIf you do not want to write a lot of code to do a basic function (I don't know why people make long methods) you can just do this:
Add namespace:
using System.Text.RegularExpressions;
In XAML, set a TextChanged property:
<TextBox x:Name="txt1" TextChanged="txt1_TextChanged"/>
In WPF under txt1_TextChanged method, add Regex.Replace
:
private void txt1_TextChanged(object sender, TextChangedEventArgs e)
{
txt1.Text = Regex.Replace(txt1.Text, "[^0-9]+", "");
}
Most databases have a native UUID type these days to make working with them easier. If yours doesn't, they're just 128-bit numbers, so you can use BINARY(16), and if you need the text format frequently, e.g. for troubleshooting, then add a calculated column to generate it automatically from the binary column. There is no good reason to store the (much larger) text form.
The object stored at d[a]
has not been set to anything. Thus, d[a]
evaluates to undefined
. You can't assign a property to undefined
:). You need to assign an object or array to d[a]
:
d[a] = [];
d[a]["greeting"] = b;
console.debug(d);
Just a note here that you may actually be better off having 3 separate SELECTS for reasons of optimization. If you have one single SELECT then the generated plan will have to project all columns col1, col2, col3, col7, col8 etc, although, depending on the value of the runtime @var, only some are needed. This may result in plans that do unnecessary clustered index lookups because the non-clustered index Doesn't cover all columns projected by the SELECT.
On the other hand 3 separate SELECTS, each projecting the needed columns only may benefit from non-clustered indexes that cover just your projected column in each case.
Of course this depends on the actual schema of your data model and the exact queries, but this is just a heads up so you don't bring the imperative thinking mind frame of procedural programming to the declarative world of SQL.
This should kind of work like die();
function die(msg = ''){
if(msg){
document.getElementsByTagName('html')[0].innerHTML = msg;
}else{
document.open();
document.write(msg);
document.close();
}
throw msg;

by using jquery to register .mousemove to document to change the image .css left and top to event.pageX and event.pageY.
example as below http://jsfiddle.net/BfLAh/1/
$(document).mousemove(function(e) {
$("#follow").css({
left: e.pageX,
top: e.pageY
});
});
_x000D_
#follow {
position: absolute;
text-align: center;
}
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="follow"><img src="https://placekitten.com/96/140" /><br>Kitteh</br>
</div>

updated to follow slowly
for the orientation , you need to get the current css left and css top and compare with event.pageX and event.pageY , then set the image orientation with
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
for the speed , you can set the jquery .animation duration to certain amount.
For the future, I've made scrollBottom into a jquery plugin, usable in the same way that scrollTop is (i.e. you can set a number and it will scroll that amount from the bottom of the page and return the number of pixels from the bottom of the page, or, return the number of pixels from the bottom of the page if no number is provided)
$.fn.scrollBottom = function(scroll){
if(typeof scroll === 'number'){
window.scrollTo(0,$(document).height() - $(window).height() - scroll);
return $(document).height() - $(window).height() - scroll;
} else {
return $(document).height() - $(window).height() - $(window).scrollTop();
}
}
//Basic Usage
$(window).scrollBottom(500);
You can use Apply and Lambda to select rows where a column contains any thing in a list. For your scenario :
df[df["col"].apply(lambda x:x not in [word1,word2,word3])]
Not sure about how other people solve this problem or whether Bootstrap has any configuration for this.
I found this thread that provides a solution:
https://github.com/twbs/bootstrap/issues/1411
One of the post suggests the use of
<ul class="dropdown-menu" style="right: 0; left: auto;">
I tested and it works.
Hope to know whether Bootstrap provides config for doing this, not via the above css.
Cheers.
CURRENT_TIMESTAMP
is only acceptable on TIMESTAMP
fields. DATETIME
fields must be left either with a null default value, or no default value at all - default values must be a constant value, not the result of an expression.

You can work around this by setting a post-insert trigger on the table to fill in a "now" value on any new records.
ORA-00907: missing right parenthesis
This is one of several generic error messages which indicate our code contains one or more syntax errors. Sometimes it may mean we literally have omitted a right bracket; that's easy enough to verify if we're using an editor which has a match bracket capability (most text editors aimed at coders do). But often it means the compiler has come across a keyword out of context. Or perhaps it's a misspelled word, a space instead of an underscore or a missing comma.
Unfortunately the possible reasons why our code won't compile is virtually infinite and the compiler just isn't clever enough to distinguish them. So it hurls a generic, slightly cryptic, message like ORA-00907: missing right parenthesis
and leaves it to us to spot the actual bloomer.
The posted script has several syntax errors. First I will discuss the error which triggers that ORA-0097 but you'll need to fix them all.
Foreign key constraints can be declared in line with the referencing column or at the table level after all the columns have been declared. These have different syntaxes; your scripts mix the two and that's why you get the ORA-00907.
In-line declaration doesn't have a comma and doesn't include the referencing column name.
CREATE TABLE historys_T (
history_record VARCHAR2 (8),
customer_id VARCHAR2 (8)
CONSTRAINT historys_T_FK FOREIGN KEY REFERENCES T_customers ON DELETE CASCADE,
order_id VARCHAR2 (10) NOT NULL,
CONSTRAINT fk_order_id_orders REFERENCES orders ON DELETE CASCADE)
Table level constraints are a separate component, and so do have a comma and do mention the referencing column.
CREATE TABLE historys_T (
history_record VARCHAR2 (8),
customer_id VARCHAR2 (8),
order_id VARCHAR2 (10) NOT NULL,
CONSTRAINT historys_T_FK FOREIGN KEY (customer_id) REFERENCES T_customers ON DELETE CASCADE,
CONSTRAINT fk_order_id_orders FOREIGN KEY (order_id) REFERENCES orders ON DELETE CASCADE)
Here is a list of other syntax errors:
HISTORYS_T
before you have created the referenced ORDERS
table.LIBRARY_T
and FORMAT_T
). DATE DEFAULT sysdate
.Looking at our own code with a cool eye is a skill we all need to gain to be successful as developers. It really helps to be familiar with Oracle's documentation. A side-by-side comparison of your code and the examples in the SQL Reference would have helped you resolved these syntax errors in considerably less than two days. Find it here (11g) and here (12c).
As well as syntax errors, your scripts contain design mistakes. These are not failures, but bad practice which should not become habits.
HISTORY_T
has constraints called historys_T_FK
and fk_order_id_orders
, neither of which is helpful. A useful convention is <child_table>_<parent_table>_fk
. So history_customer_fk
and history_order_fk
respectively.LIBRARY_T
and FORMATS
. You could do this by creating the constraints in separate statement but don't: you will have problems when inserting rows and even worse problems with deletions. You should reconsider your data model and find a way to model the relationship between the two tables so that one is the parent and the other the child. Or perhaps you need a different kind of relationship, such as an intersection table.LIBRARY_T
is ugly. Try to find a more expressive name which doesn't require a needless suffix to avoid a keyword clash.T_CUSTOMERS
is even uglier, being both inconsistent with your other tables and completely unnecessary, as customers
is not a keyword.Naming things is hard. You wouldn't believe the wrangles I've had about table names over the years. The most important thing is consistency. If I look at a data dictionary and see tables called T_CUSTOMERS
and LIBRARY_T
my first response would be confusion. Why are these tables named with different conventions? What conceptual difference does this express? So, please, decide on a naming convention and stick to. Make your table names either all singular or all plural. Avoid prefixes and suffixes as much as possible; we already know it's a table, we don't need a T_
or a _TAB
.
Posed question
Responding to the question 'what metric should be used for multi-class classification with imbalanced data': Macro-F1-measure. Macro Precision and Macro Recall can be also used, but they are not so easily interpretable as for binary classificaion, they are already incorporated into F-measure, and excess metrics complicate methods comparison, parameters tuning, and so on.
Micro averaging are sensitive to class imbalance: if your method, for example, works good for the most common labels and totally messes others, micro-averaged metrics show good results.
Weighting averaging isn't well suited for imbalanced data, because it weights by counts of labels. Moreover, it is too hardly interpretable and unpopular: for instance, there is no mention of such an averaging in the following very detailed survey I strongly recommend to look through:
Sokolova, Marina, and Guy Lapalme. "A systematic analysis of performance measures for classification tasks." Information Processing & Management 45.4 (2009): 427-437.
Application-specific question
However, returning to your task, I'd research 2 topics:
Commonly used metrics. As I can infer after looking through literature, there are 2 main evaluation metrics:
Yu, April, and Daryl Chang. "Multiclass Sentiment Prediction using Yelp Business."
(link) - note that the authors work with almost the same distribution of ratings, see Figure 5.
Pang, Bo, and Lillian Lee. "Seeing stars: Exploiting class relationships for sentiment categorization with respect to rating scales." Proceedings of the 43rd Annual Meeting on Association for Computational Linguistics. Association for Computational Linguistics, 2005.
(link)
Lee, Moontae, and R. Grafe. "Multiclass sentiment analysis with restaurant reviews." Final Projects from CS N 224 (2010).
(link) - they explore both accuracy and MSE, considering the latter to be better
Pappas, Nikolaos, Rue Marconi, and Andrei Popescu-Belis. "Explaining the Stars: Weighted Multiple-Instance Learning for Aspect-Based Sentiment Analysis." Proceedings of the 2014 Conference on Empirical Methods In Natural Language Processing. No. EPFL-CONF-200899. 2014.
(link) - they utilize scikit-learn for evaluation and baseline approaches and state that their code is available; however, I can't find it, so if you need it, write a letter to the authors, the work is pretty new and seems to be written in Python.
Cost of different errors. If you care more about avoiding gross blunders, e.g. assinging 1-star to 5-star review or something like that, look at MSE; if difference matters, but not so much, try MAE, since it doesn't square diff; otherwise stay with Accuracy.
About approaches, not metrics
Try regression approaches, e.g. SVR, since they generally outperforms Multiclass classifiers like SVC or OVA SVM.
If you would need to escape special characters like '_' (underscore), as it was in my case, and you are not willing/not able to define an ESCAPE clause, you may wish to enclose the special character with square brackets '[' and ']'.
This explains the meaning of the "weird" string '[[]' - it just embraces the '[' character with square brackets, effectively escaping it.
My use case was to specify the name of a stored procedure with underscores in it as a filter criteria for the Profiler. So I've put string '%name[_]of[_]a[_]stored[_]procedure%' in a TextData LIKE field and it gave me trace results I wanted to achieve.
Here is a good example from the documentation: LIKE (Transact-SQL) - Using Wildcard Characters As Literals
You can't pass parameters like this - the success object maps to an anonymous function with one parameter and that's the received data. Create a function outside of the for loop which takes (data, i)
as parameters and perform the code there:
function image_link(data, i) {
$(data).find("a:contains(.jpg)").each(function(){
new Image().src = url[i] + $(this).attr("href");
}
}
...
success: function(data){
image_link(data, i)
}
As others have explained, the built-in dict
does not do what you want. But in Python2 (and probably 3 too) you can easily create a ValueDict
class that copies with =
so you can be sure that the original will not change.
class ValueDict(dict):
def __ilshift__(self, args):
result = ValueDict(self)
if isinstance(args, dict):
dict.update(result, args)
else:
dict.__setitem__(result, *args)
return result # Pythonic LVALUE modification
def __irshift__(self, args):
result = ValueDict(self)
dict.__delitem__(result, args)
return result # Pythonic LVALUE modification
def __setitem__(self, k, v):
raise AttributeError, \
"Use \"value_dict<<='%s', ...\" instead of \"d[%s] = ...\"" % (k,k)
def __delitem__(self, k):
raise AttributeError, \
"Use \"value_dict>>='%s'\" instead of \"del d[%s]" % (k,k)
def update(self, d2):
raise AttributeError, \
"Use \"value_dict<<=dict2\" instead of \"value_dict.update(dict2)\""
# test
d = ValueDict()
d <<='apples', 5
d <<='pears', 8
print "d =", d
e = d
e <<='bananas', 1
print "e =", e
print "d =", d
d >>='pears'
print "d =", d
d <<={'blueberries': 2, 'watermelons': 315}
print "d =", d
print "e =", e
print "e['bananas'] =", e['bananas']
# result
d = {'apples': 5, 'pears': 8}
e = {'apples': 5, 'pears': 8, 'bananas': 1}
d = {'apples': 5, 'pears': 8}
d = {'apples': 5}
d = {'watermelons': 315, 'blueberries': 2, 'apples': 5}
e = {'apples': 5, 'pears': 8, 'bananas': 1}
e['bananas'] = 1
# e[0]=3
# would give:
# AttributeError: Use "value_dict<<='0', ..." instead of "d[0] = ..."
Please refer to the lvalue modification pattern discussed here: Python 2.7 - clean syntax for lvalue modification. The key observation is that str
and int
behave as values in Python (even though they're actually immutable objects under the hood). While you're observing that, please also observe that nothing is magically special about str
or int
. dict
can be used in much the same ways, and I can think of many cases where ValueDict
makes sense.
You can't update with a number greater than 1 for datatype number(2,2)
is because, the first parameter is the total number of digits in the number and the second one (.i.e 2 here) is the number of digits in decimal part. I guess you can insert or update data < 1
. i.e. 0.12, 0.95 etc.
Please check NUMBER DATATYPE in NUMBER Datatype.
What about trying with VLOOKUP
? The syntax is:
=VLOOKUP(cell you want to copy, range you want to copy, 1, FALSE).
It should do the trick.
It is highly unlikely that adding NameVirtualHost *:443
is the right solution, because there are a limited number of situations in which it is possible to support name-based virtual hosts over SSL. Read this and this for some details (there may be better docs out there; these were just ones I found that discuss the issue in detail).
If you're running a relatively stock Apache configuration, you probably have this somewhere:
<VirtualHost _default_:443>
Your best bet is to either:
VirtualHost
container, or VirtualHost
block and create a new one. Don't forget to include all the relevant SSL options.I was having the same error - ImportError: No module named PyQt4.QtGui
. Instead of running your python file (which uses PyQt) on the terminal as -
python file_name.py
Run it with sudo privileges -
sudo python file_name.py
This worked for me!
Both the answers I see work fine in Informix specifically, and are basically standard SQL. That is, the notation:
INSERT INTO target_table[(<column-list>)] SELECT ... FROM ...;
works fine with Informix and, I would expect, all the DBMS. (Once upon 5 or more years ago, this is the sort of thing that MySQL did not always support; it now has decent support for this sort of standard SQL syntax and, AFAIK, it would work OK on this notation.) The column list is optional but indicates the target columns in sequence, so the first column of the result of the SELECT will go into the first listed column, etc. In the absence of the column list, the first column of the result of the SELECT goes into the first column of the target table.
What can be different between systems is the notation used to identify tables in different databases - the standard has nothing to say about inter-database (let alone inter-DBMS) operations. With Informix, you can use the following notation to identify a table:
[dbase[@server]:][owner.]table
That is, you may specify a database, optionally identifying the server that hosts that database if it is not in the current server, followed by an optional owner, dot, and finally the actual table name. The SQL standard uses the term schema for what Informix calls the owner. Thus, in Informix, any of the following notations could identify a table:
table
"owner".table
dbase:table
dbase:owner.table
dbase@server:table
dbase@server:owner.table
The owner in general does not need to be quoted; however, if you do use quotes, you need to get the owner name spelled correctly - it becomes case-sensitive. That is:
someone.table
"someone".table
SOMEONE.table
all identify the same table. With Informix, there's a mild complication with MODE ANSI databases, where owner names are generally converted to upper-case (informix is the exception). That is, in a MODE ANSI database (not commonly used), you could write:
CREATE TABLE someone.table ( ... )
and the owner name in the system catalog would be "SOMEONE", rather than 'someone'. If you enclose the owner name in double quotes, it acts like a delimited identifier. With standard SQL, delimited identifiers can be used many places. With Informix, you can use them only around owner names -- in other contexts, Informix treats both single-quoted and double-quoted strings as strings, rather than separating single-quoted strings as strings and double-quoted strings as delimited identifiers. (Of course, just for completeness, there is an environment variable, DELIMIDENT, that can be set - to any value, but Y is safest - to indicate that double quotes always surround delimited identifiers and single quotes always surround strings.)
Note that MS SQL Server manages to use [delimited identifiers] enclosed in square brackets. It looks weird to me, and is certainly not part of the SQL standard.
This builds on ntc2 and Chris Johnsen's answer. I am using this whenever I want to create a new session with a custom history-limit. I wanted a way to create sessions with limited scrollback without permanently changing my history-limit for future sessions.
tmux set-option -g history-limit 100 \; new-session -s mysessionname \; set-option -g history-limit 2000
This works whether or not there are existing sessions. After setting history-limit for the new session it resets it back to the default which for me is 2000.
I created an executable bash script that makes this a little more useful. The 1st parameter passed to the script sets the history-limit for the new session and the 2nd parameter sets its session name:
#!/bin/bash
tmux set-option -g history-limit "${1}" \; new-session -s "${2}" \; set-option -g history-limit 2000
From the current file path you could use:
os.path.join(os.path.dirname(__file__),'..','img','banner.png')
Just use
filter_input(INPUT_METHOD_NAME, 'var_name')
instead of $_INPUT_METHOD_NAME['var_name']
filter_input_array(INPUT_METHOD_NAME)
instead of $_INPUT_METHOD_NAME
e.g
$host= filter_input(INPUT_SERVER, 'HTTP_HOST');
echo $host;
instead of
$host= $_SERVER['HTTP_HOST'];
echo $host;
And use
var_dump(filter_input_array(INPUT_SERVER));
instead of
var_dump($_SERVER);
N.B: Apply to all other Super Global variable
The following from Paul Tarjan worked for me,
var data = { 'user_ids[]' : []};
$(":checked").each(function() {
data['user_ids[]'].push($(this).val());
});
$.post("ajax.php", data);
but I had multiple forms on my page and it pulled checked boxes from all forms, so I made the following modification so it only pulled from one form,
var data = { 'user_ids[]' : []};
$('#name_of_your_form input[name="user_ids[]"]:checked').each(function() {
data['user_ids[]'].push($(this).val());
});
$.post("ajax.php", data);
Just change name_of_your_form to the name of your form.
I'll also mention that if a user doesn't check any boxes then no array isset in PHP. I needed to know if a user unchecked all the boxes, so I added the following to the form,
<input style="display:none;" type="checkbox" name="user_ids[]" value="none" checked="checked"></input>
This way if no boxes are checked, it will still set the array with a value of "none".
The query component is indicated by the first ?
in a URI. "Query string" might be a synonym (this term is not used in the URI standard).
Some examples for HTTP URIs with query components:
http://example.com/foo?bar
http://example.com/foo/foo/foo?bar/bar/bar
http://example.com/?bar
http://example.com/?@bar._=???/1:
http://example.com/?bar1=a&bar2=b
(list of allowed characters in the query component)
The "format" of the query component is up to the URI authors. A common convention (but nothing more than a convention, as far as the URI standard is concerned¹) is to use the query component for key-value pairs, aka. parameters, like in the last example above: bar1=a&bar2=b
.
Such parameters could also appear in the other URI components, i.e., the path² and the fragment. As far as the URI standard is concerned, it’s up to you which component and which format to use.
Example URI with parameters in the path, the query, and the fragment:
http://example.com/foo;key1=value1?key2=value2#key3=value3
¹ The URI standard says about the query component:
[…] query components are often used to carry identifying information in the form of "key=value" pairs […]
² The URI standard says about the path component:
[…] the semicolon (";") and equals ("=") reserved characters are often used to delimit parameters and parameter values applicable to that segment. The comma (",") reserved character is often used for similar purposes.
i solve by way nuget. the first you install nuget.
the second you use.
illustration follow:
third : Check to see if this is the latest version by looking at the "Version" property.
The finaly : you check project have latest version again.
Both
SuperClass.__init__(self, x)
or
super(SubClass,self).__init__( x )
will work (I prefer the 2nd one, as it adheres more to the DRY principle).

Cron jobs usually are stored in a per-user file under /var/spool/cron
The simplest thing for you to do is probably just create a text file with the job configured, then copy it to the cron spool folder and make sure it has the right permissions (600).
If you are using windows 10 or windows server 2012, the steps to change the java runtime version is this:
In order to keep leading zeroes, here is a small variation on what has Paul suggested (eg md5 hash):
public static String MD5hash(String text) throws NoSuchAlgorithmException {
byte[] hash = MessageDigest.getInstance("MD5").digest(text.getBytes());
return String.format("%032x",new BigInteger(1, hash));
}
Oops, this looks poorer than what's Ayman proposed, sorry for that
To bypass google's check, which is what you really want, simply remove the extensions from the file when you send it, and add them back after you download it. For example:
as per @anaximander s answer but your signup action should look more like
[HttpPost]
public ActionResult SignUp(Account account)
{
if(ModelState.IsValid){
//do something with account
return RedirectToAction("Index");
}
return View("SignUp");
}
I know this is an old question, but the problem is not going away soon. CSV files are easy to generate from most programming languages, rather small, human-readable in a crunch with a plain text editor, and ubiquitous.
The problem is not only with dates in text fields, but anything numeric also gets converted from text to numbers. A couple of examples where this is problematic:
which sometimes can start with one or more zeroes (0), which get thrown away when converted to numeric. Or the value contains characters that can be confused with mathematical operators (as in dates: /, -).
Two cases that I can think of that the "prepending =" solution, as mentioned previously, might not be ideal is
If one pre/appends a non-numeric and/or non-date character in the value, the value will be recognized as text and not converted. A non-printing character would be good as it will not alter the displayed value. However, the plain old space character (\s, ASCII 32) doesn't work for this as it gets chopped off by Excel and then the value still gets converted. But there are various other printing and non-printing space characters that will work well. The easiest however is to append (add after) the simple tab character (\t, ASCII 9).
Benefits of this approach:
If there's a reason you don't want to use the tab, look in an Unicode table for something else suitable.
might be to generate XML files, for which a certain format also is accepted for import by newer MS Excel versions, and which allows a lot more options similar to .XLS format, but I don't have experience with this.
So there are various options. Depending on your requirements/application, one might be better than another.
It needs to be said that newer versions (2013+) of MS Excel don't open the CSV in spreadsheet format any more - one more speedbump in one's workflow making Excel less useful... At least, instructions exist for getting around it. See e.g. this Stackoverflow: How to correctly display .csv files within Excel 2013? .
I run a large number of PHP daemons.
I agree with you that PHP is not the best (or even a good) language for doing this, but the daemons share code with the web-facing components so overall it is a good solution for us.
We use daemontools for this. It is smart, clean and reliable. In fact we use it for running all of our daemons.
You can check this out at http://cr.yp.to/daemontools.html.

I've added support for this in my fork of angular. It allows you to specify

If they are generated from PHP, and they contain string values, use the escaped quoting around each variables like this:
<?php
echo '<a href=# onclick="return ReAssign(\'' + $valuationId + '\',\'' + $user + '\')">Re-Assign</a>';
?>
The logic is similar to the updated code in the question, which generates code using JavaScript (maybe using jQuery?): don't forget to apply the escaped quotes to each variable:
var user = element.UserName;
var valuationId = element.ValuationId;
$('#ValuationAssignedTable').append('<tr> <td><a href=# onclick="return ReAssign(\'' + valuationId + '\',\'' + user + '\')">Re-Assign</a> </td> </tr>');
The moral of the story is
'someString(\''+'otherString'+','+'yetAnotherString'+'\')'
Will get evaluated as:
someString('otherString,yetAnotherString');
Whereas you would need:
someString('otherString','yetAnotherString');
In WPF, the background is not a Color
, it is a Brush
. So, try this for starters:
using System.Windows.Media;
// ....
ButtonToday.Background = new SolidColorBrush(Colors.Red);
More sensibly, though, you should probably look at doing this in your Xaml instead of in code.
Rename your file, commit the changes including the "deleted" file, and don't include the new (renamed) file.
Rename your file back.
The correct parameter to set the maximum length is:
SET @@group_concat_max_len = value_numeric;
value_numeric
must be > 1024; by default the group_concat_max_len
value is 1024.
in the form load event add this line
this.WindowState = FormWindowState.Maximized;
Try this...
SELECT TO_CHAR(column_name,'99G999D99MI')
as format_column
FROM DUAL;
Now to answer the question that perhaps you should have asked, like "I'm getting 100 floats form somewhere; do I need to put them in an array or list before I find the minimum?"
Answer: No, if somewhere
is a iterable, instead of doing this:
temp = []
for x in somewhere:
temp.append(x)
answer = min(temp)
you can do this:
answer = min(somewhere)
Example:
answer = min(float(line) for line in open('floats.txt'))
You could simply create a sub-routine:
#Get File Contents
sub gfc
{
open FC, @_[0];
join '', <FC>;
}
i did this but long ago in version: v0.2.10 of UI-router like something like this::
$stateProvider
.state(
'home', {
url: '/home',
views: {
'': {
templateUrl: Url.resolveTemplateUrl('shared/partial/main.html'),
controller: 'mainCtrl'
},
}
})
.state('home.login', {
url: '/login',
templateUrl: Url.resolveTemplateUrl('authentication/partial/login.html'),
controller: 'authenticationCtrl'
})
.state('home.logout', {
url: '/logout/:state',
controller: 'authenticationCtrl'
})
.state('home.reservationChart', {
url: '/reservations/?vw',
views: {
'': {
templateUrl: Url.resolveTemplateUrl('reservationChart/partial/reservationChartContainer.html'),
controller: 'reservationChartCtrl',
reloadOnSearch: false
},
'[email protected]': {
templateUrl: Url.resolveTemplateUrl('voucher/partial/viewVoucherContainer.html'),
controller: 'viewVoucherCtrl',
reloadOnSearch: false
},
'[email protected]': {
templateUrl: Url.resolveTemplateUrl('voucher/partial/voucherContainer.html'),
controller: 'voucherCtrl',
reloadOnSearch: false
}
},
reloadOnSearch: false
})
In this case a relatively simple GROUP BY
can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER()
:
Runnable example (Wofkflow20 error in original data corrected)
;WITH partitioned AS (
SELECT company
,workflow
,date
,other_columns
,ROW_NUMBER() OVER(PARTITION BY company, workflow
ORDER BY date) AS seq
FROM workflowTable
)
SELECT *
FROM partitioned WHERE seq = 1
os.path.splitext()
, os.rename()
for example:
# renamee is the file getting renamed, pre is the part of file name before extension and ext is current extension
pre, ext = os.path.splitext(renamee)
os.rename(renamee, pre + new_extension)

Here is a part of the response that tells you if an element is in the viewport. You may need to check if there is nothing on top of it using elementFromPoint, but it's a bit longer.
function isInViewport(element) {
var rect = element.getBoundingClientRect();
var windowHeight = window.innerHeight || document.documentElement.clientHeight;
var windowWidth = window.innerWidth || document.documentElement.clientWidth;
return rect.bottom > 0 && rect.top < windowHeight && rect.right > 0 && rect.left < windowWidth;
}
One thing to also keep in mind if .gitignore
does not seem to be ignoring untracked files is that you should not have comments on the same line as the ignores. So this is okay
# ignore all foo.txt, foo.markdown, foo.dat, etc.
foo*
But this will not work:
foo* # ignore all foo.txt, foo.markdown, foo.dat, etc.
.gitignore
interprets the latter case as "ignore files named "foo* # ignore all foo.txt, foo.markdown, foo.dat, etc."
, which, of course, you don't have.
I can't comment so here goes. About @David Storey answer.
Be careful on the "order of execution" in CSS3 chains! The order is right to left, not left to right.
transformation: translate(0,10%) rotate(25deg);
The rotate
operation is done first, then the translate
.
See: CSS3 transform order matters: rightmost operation first
If you are using iframe in your webpage you might encounter a problem while changing the whole page through a HTML hyperlink (anchor tag) from the iframe. There are two solutions to mitigate this problem.
Solution 1. You can use target attribute of anchor tag as given in the following example.
<a target="_parent" href="http://www.kriblog.com">link</a>
Solution 2. You can also open a new page in parent window from iframe with JavaScript.
<a href="#" onclick="window.parent.location.href='http://www.kriblog.com';">
Remember ? target="_parent"
has been deprecated in XHTML, but it is still supported in HTML 5.x.
More can be read from following link http://www.kriblog.com/html/link-of-iframe-open-in-the-parent-window.html
if using TypeScript, you can use the spread operator (...
)
var json = {...json1,...json2}
You need a back inserter to copy into vectors:
std::copy(str.c_str(), str.c_str()+str.length(), back_inserter(data));
Not sure if there are still people looking for an explanation and a solution. The comments above say it all on the differences between TRUE / FALSE / 1 / 0.
I would just like to bring my 2 cents for the way to display the actual value.
If you're working with a Boolean datatype, you're looking for a TRUE vs. FALSE result; if you store it in MySQL, it will be stored as 1 resp. 0 (if I'm not mistaking, this is the same in your server's memory).
So to display the the value in PHP, you need to check if it is true (1) or false (0) and display whatever you want: "TRUE" or "FALSE" or possibly "1" or "0".
Attention, everything bigger (or different) than 0 will also be considered as TRUE in PHP. E.g.: 2, "abc", etc. will all return TRUE.
If you're working with a number datatype, the way it is stored is the same.
To display the value, you need to tell PHP to handle it as a number. The easiest way I found is to multiply it by 1.
In visual studio, go to help | about and look at the version of Visual Studio that you're using to compile your app.
If you actually want Yes and No buttons (and assuming WinForms):
void button_Click(object sender, EventArgs e)
{
var message = "Yes or No?";
var title = "Hey!";
var result = MessageBox.Show(
message, // the message to show
title, // the title for the dialog box
MessageBoxButtons.YesNo, // show two buttons: Yes and No
MessageBoxIcon.Question); // show a question mark icon
// the following can be handled as if/else statements as well
switch (result)
{
case DialogResult.Yes: // Yes button pressed
MessageBox.Show("You pressed Yes!");
break;
case DialogResult.No: // No button pressed
MessageBox.Show("You pressed No!");
break;
default: // Neither Yes nor No pressed (just in case)
MessageBox.Show("What did you press?");
break;
}
}

You must set proxy for http and https
systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=user
systemProp.http.proxyPassword=password
systemProp.http.nonProxyHosts=localhost
systemProp.http.auth.ntlm.domain=domain
systemProp.https.proxyHost=www.somehost.org
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=user
systemProp.https.proxyPassword=password
systemProp.https.nonProxyHosts=localhost
systemProp.https.auth.ntlm.domain=domain
if you set proxy from File -> Settings ->HTTP Proxy(Under IDE Settings) it only define http proxy and does not set https proxy
appendChild

I don't much like an idea of writing binary protobuf to database, because it can one day become not backward-compatible with newer versions and break the system that way.
Converting protobuf to JSON for storage and then back to protobuf on load is much more likely to create compatibility problems, because:
With all that said, there are many libraries out there for converting protobufs to JSON, usually built on the Protobuf reflection interface (not to be confused with the Java reflection interface; Protobuf reflection is offered by the com.google.protobuf.Message
interface).
If you're not afraid of old java-style (non type safe generic) semantics, this also works and is simple'ish:
ArgumentCaptor<List> argument = ArgumentCaptor.forClass(List.class);
verify(subject.method(argument.capture()); // run your code
List<SomeType> list = argument.getValue(); // first captured List, etc.
All answers above are awesome
Also add this otherwise your app will crash like mine without any reason
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
This finally became a part of support v4 library, NestedScrollView. So, no longer local hacks is needed for most of cases I'd guess.
To get the number of selected rows I usually use the following:
cursor.execute(sql)
count = (len(cursor.fetchall))
Just use a compiler (or provide it with the arguments it needs) such that it compiles for a more recent version of the C standard, C99 or C11. E.g for the GCC family of compilers that would be -std=c99
.
Your primary question has been answered above. I just wanted to point out that the regex you're using has a bug. It will also succeed on foo-domain.com
which is not a subdomain of domain.com
What you really want is this:
/(^|\.)domain\.com$/
In ubuntu to install php_soap
on PHP7 use below commands. Reference
sudo apt-get install php7.0-soap
sudo systemctl restart apache2.service
For older version of php use below command and restart apache.
apt-get install php-soap
int i;
int j;
int * const ptr1 = &i;
The compiler will stop you changing ptr1
.
const int * ptr2 = &i;
The compiler will stop you changing *ptr2
.
ptr1 = &j; // error
*ptr1 = 7; // ok
ptr2 = &j; // ok
*ptr2 = 7; // error
Note that you can still change *ptr2
, just not by literally typing *ptr2
:
i = 4;
printf("before: %d\n", *ptr2); // prints 4
i = 5;
printf("after: %d\n", *ptr2); // prints 5
*ptr2 = 6; // still an error
You can also have a pointer with both features:
const int * const ptr3 = &i;
ptr3 = &j; // error
*ptr3 = 7; // error
The most versatile and safe method is putting the comment into a void quoted
here-document
, like this:
<<"COMMENT"
This long comment text includes ${parameter:=expansion}
`command substitution` and $((arithmetic++ + --expansion)).
COMMENT
Quoting the COMMENT
delimiter above is necessary to prevent parameter
expansion, command substitution and arithmetic expansion, which would happen
otherwise, as Bash manual states and POSIX shell standard specifies.
In the case above, not quoting COMMENT
would result in variable parameter
being assigned text expansion
, if it was empty or unset, executing command
command substitution
, incrementing variable arithmetic
and decrementing
variable expansion
.
Comparing other solutions to this:
Using if false; then comment text fi
requires the comment text to be
syntactically correct Bash code whereas natural comments are often not, if
only for possible unbalanced apostrophes. The same goes for : || { comment text }
construct.
Putting comments into a single-quoted void command argument, as in :'comment
text'
, has the drawback of inability to include apostrophes. Double-quoted
arguments, as in :"comment text"
, are still subject to parameter expansion,
command substitution and arithmetic expansion, the same as unquoted
here-document contents and can lead to the side-effects described above.
Using scripts and editor facilities to automatically prefix each line in a block with '#' has some merit, but doesn't exactly answer the question.
I tried experimenting with the answers given. My personal finding came out to be:
git rm -r --cached .
And then
git add .
This seemed to make my working directory nice and clean. You can put your fileName in place of the dot.
I had the same problem too, and tried to solve it by setting explicitly the http.proxyAuthMethod to basic.
After running a pcap trace between my server and the proxy, i noticed that the " HTTP CONNECT" request sent to the proxy during a git clone still not have a "Proxy-Authorization" header set to basic. This was due to my git version "1.8.3.1" that do not support http.proxyAuthMethod.
After installing a newest git version (2.16.6), using rpm packages foud here "https://repo.ius.io/7/x86_64/packages/g/", setting http.proxyAuthMethod to basic had finally an effect on git behavior and then my git clone was successful.
I hope this helps
You can use following java code to get new inserted id.
ps = con.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
ps.setInt(1, quizid);
ps.setInt(2, userid);
ps.executeUpdate();
ResultSet rs = ps.getGeneratedKeys();
if (rs.next()) {
lastInsertId = rs.getInt(1);
}
You can do it entirely in JavaScript:
IE has (for a long time) standard API for clearing Basic Authentication cache:
document.execCommand("ClearAuthenticationCache")
Should return true when it works. Returns either false, undefined or blows up on other browsers.
New browsers (as of Dec 2012: Chrome, FireFox, Safari) have "magic" behavior. If they see a successful basic auth request with any bogus other username (let's say logout
) they clear the credentials cache and possibly set it for that new bogus user name, which you need to make sure is not a valid user name for viewing content.
Basic example of that is:
var p = window.location.protocol + '//'
// current location must return 200 OK for this GET
window.location = window.location.href.replace(p, p + 'logout:password@')
An "asynchronous" way of doing the above is to do an AJAX call utilizing the logout
username. Example:
(function(safeLocation){
var outcome, u, m = "You should be logged out now.";
// IE has a simple solution for it - API:
try { outcome = document.execCommand("ClearAuthenticationCache") }catch(e){}
// Other browsers need a larger solution - AJAX call with special user name - 'logout'.
if (!outcome) {
// Let's create an xmlhttp object
outcome = (function(x){
if (x) {
// the reason we use "random" value for password is
// that browsers cache requests. changing
// password effectively behaves like cache-busing.
x.open("HEAD", safeLocation || location.href, true, "logout", (new Date()).getTime().toString())
x.send("")
// x.abort()
return 1 // this is **speculative** "We are done."
} else {
return
}
})(window.XMLHttpRequest ? new window.XMLHttpRequest() : ( window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : u ))
}
if (!outcome) {
m = "Your browser is too old or too weird to support log out functionality. Close all windows and restart the browser."
}
alert(m)
// return !!outcome
})(/*if present URI does not return 200 OK for GET, set some other 200 OK location here*/)
You can make it a bookmarklet too:
javascript:(function(c){var a,b="You should be logged out now.";try{a=document.execCommand("ClearAuthenticationCache")}catch(d){}a||((a=window.XMLHttpRequest?new window.XMLHttpRequest:window.ActiveXObject?new ActiveXObject("Microsoft.XMLHTTP"):void 0)?(a.open("HEAD",c||location.href,!0,"logout",(new Date).getTime().toString()),a.send(""),a=1):a=void 0);a||(b="Your browser is too old or too weird to support log out functionality. Close all windows and restart the browser.");alert(b)})(/*pass safeLocation here if you need*/);
EXPLORING DOCKER IMAGE!
bash
or sh
...Inspect the image first: docker inspect name-of-container-or-image
Look for entrypoint
or cmd
in the JSON return.
docker run --rm -it --entrypoint=/bin/bash name-of-image
once inside do: ls -lsa
or any other shell command like: cd ..
The -it
stands for interactive... and TTY. The --rm
stands for remove container after run.
If there are no common tools like ls
or bash
present and you have access to the Dockerfile
simple add the common tool as a layer.
example (alpine Linux):
RUN apk add --no-cache bash
And when you don't have access to the Dockerfile
then just copy/extract the files from a newly created container and look through them:
docker create <image> # returns container ID the container is never started.
docker cp <container ID>:<source_path> <destination_path>
docker rm <container ID>
cd <destination_path> && ls -lsah
I don't use commands. You should be able to do this using the GUI:
Visual Studio\Projects\{your project}
folder. Select OK.Unlike an int
(whole number), a float
have a decimal point, and so can a double
.
But the difference between the two is that a double
is twice as detailed as a float
, meaning that it can have double the amount of numbers after the decimal point.
In SQL, NULL = NULL is false, you usually have to use IS NULL:
SELECT CASE WHEN MAX(id) IS NULL THEN 0 ELSE (MAX(id) + 1) END FROM words
But, if you want the number of rows, you should just use count(id)
since your solution will give 10 if your rows are (0,1,3,5,9) where it should give 5.
If you can guarantee you will always ids from 0 to N, max(id)+1 may be faster depending on the index implementation (it may be faster to traverse the right side of a balanced tree rather than traversing the whole tree, counting.
But that's very implementation-specific and I would advise against relying on it, not least because it locks your performance to a specific DBMS.
For simple solutions you can just Overwrite the "toString" in your object
public class User{
public int ID;
public String name;
@Override
public String toString() {
return name;
}
}
and then you can use:
ArrayAdapter<User> dataAdapter = new ArrayAdapter<User>(mContext, android.R.layout.simple_spinner_item, listOfUsers);
This way your spinner will show only the user names.
Try this:
I used for Update and Delete buttons. It doesn't touch Edit button. You can use auto generated buttons.
protected void gvOperators_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType != DataControlRowType.DataRow) return;
var updateButton = (LinkButton)e.Row.Cells[0].Controls[0];
if (updateButton.Text == "Update")
{
updateButton.OnClientClick = "return confirm('Do you really want to update?');";
}
var deleteButton = (LinkButton)e.Row.Cells[0].Controls[2];
if (deleteButton.Text == "Delete")
{
deleteButton.OnClientClick = "return confirm('Do you really want to delete?');";
}
}
I know this question asked quite long time ago but for the new users of this question. Please read this article where contains complete description on upcasting, downcasting and use of instanceof operator
There's no need to upcast manually, it happens on its own:
Mammal m = (Mammal)new Cat();
equals to Mammal m = new Cat();
But downcasting must always be done manually:
Cat c1 = new Cat();
Animal a = c1; //automatic upcasting to Animal
Cat c2 = (Cat) a; //manual downcasting back to a Cat
Why is that so, that upcasting is automatical, but downcasting must be manual? Well, you see, upcasting can never fail. But if you have a group of different Animals and want to downcast them all to a Cat, then there's a chance, that some of these Animals are actually Dogs, and process fails, by throwing ClassCastException. This is where is should introduce an useful feature called "instanceof", which tests if an object is instance of some Class.
Cat c1 = new Cat();
Animal a = c1; //upcasting to Animal
if(a instanceof Cat){ // testing if the Animal is a Cat
System.out.println("It's a Cat! Now i can safely downcast it to a Cat, without a fear of failure.");
Cat c2 = (Cat)a;
}
For more information please read this article
You can checkup for the special variable __name__
with this simple example:
create file1.py
if __name__ == "__main__":
print("file1 is being run directly")
else:
print("file1 is being imported")
create file2.py
import file1 as f1
print("__name__ from file1: {}".format(f1.__name__))
print("__name__ from file2: {}".format(__name__))
if __name__ == "__main__":
print("file2 is being run directly")
else:
print("file2 is being imported")
Execute file2.py
output:
file1 is being imported
__name__ from file1: file1
__name__ from file2: __main__
file2 is being run directly
Using the [key] didn't work for me but using an id property does it. I just add this property in my class.
public int id {get; set;}
Add at the top:
SET DATEFORMAT ymd;
or whichever format you are using in your queries
There is a way that's pretty memory inefficient.
single file:
import hashlib
def file_as_bytes(file):
with file:
return file.read()
print hashlib.md5(file_as_bytes(open(full_path, 'rb'))).hexdigest()
list of files:
[(fname, hashlib.md5(file_as_bytes(open(fname, 'rb'))).digest()) for fname in fnamelst]
Recall though, that MD5 is known broken and should not be used for any purpose since vulnerability analysis can be really tricky, and analyzing any possible future use your code might be put to for security issues is impossible. IMHO, it should be flat out removed from the library so everybody who uses it is forced to update. So, here's what you should do instead:
[(fname, hashlib.sha256(file_as_bytes(open(fname, 'rb'))).digest()) for fname in fnamelst]
If you only want 128 bits worth of digest you can do .digest()[:16]
.
This will give you a list of tuples, each tuple containing the name of its file and its hash.
Again I strongly question your use of MD5. You should be at least using SHA1, and given recent flaws discovered in SHA1, probably not even that. Some people think that as long as you're not using MD5 for 'cryptographic' purposes, you're fine. But stuff has a tendency to end up being broader in scope than you initially expect, and your casual vulnerability analysis may prove completely flawed. It's best to just get in the habit of using the right algorithm out of the gate. It's just typing a different bunch of letters is all. It's not that hard.
Here is a way that is more complex, but memory efficient:
import hashlib
def hash_bytestr_iter(bytesiter, hasher, ashexstr=False):
for block in bytesiter:
hasher.update(block)
return hasher.hexdigest() if ashexstr else hasher.digest()
def file_as_blockiter(afile, blocksize=65536):
with afile:
block = afile.read(blocksize)
while len(block) > 0:
yield block
block = afile.read(blocksize)
[(fname, hash_bytestr_iter(file_as_blockiter(open(fname, 'rb')), hashlib.md5()))
for fname in fnamelst]
And, again, since MD5 is broken and should not really ever be used anymore:
[(fname, hash_bytestr_iter(file_as_blockiter(open(fname, 'rb')), hashlib.sha256()))
for fname in fnamelst]
Again, you can put [:16]
after the call to hash_bytestr_iter(...)
if you only want 128 bits worth of digest.
strstr(request, "favicon") != NULL

var thumbnailHold;
$(".image_thumb").mousedown(function() {

You don't need to cast it because it's the same Object type, you just need to dereference it.
I implemented this easy with a bit different approach.
My custom FragmentAdapter.getItem method returned not new MyFragment(), but the instance of MyFragment that was created in FragmentAdapter constructor.
In my activity I then got the fragment from the adapter, check if it is instanceOf needed Fragment, then cast and use needed methods.
The following snippet worked for me.
@Html.TextBoxFor(m => m.Crown, new { id = "", @style = "padding-left:5px", @readonly = "true" })
I think your cron is not correct. According to what you described, you may need to change cron schedule to
*/5 * * * *
What you put in your schedule now mean it will poll the SCM at 5 past of every hour.
nth-last-child
sounds like it was specifically designed to solve this problem, so I doubt whether there is a more compatible alternative. Support looks pretty decent, though.
Easily done in 2 steps:
dictionary[new_key] = dictionary[old_key]
del dictionary[old_key]
Or in 1 step:
dictionary[new_key] = dictionary.pop(old_key)
which will raise KeyError
if dictionary[old_key]
is undefined. Note that this will delete dictionary[old_key]
.
>>> dictionary = { 1: 'one', 2:'two', 3:'three' }
>>> dictionary['ONE'] = dictionary.pop(1)
>>> dictionary
{2: 'two', 3: 'three', 'ONE': 'one'}
>>> dictionary['ONE'] = dictionary.pop(1)
Traceback (most recent call last):

Here is a simple adaptation from some answers above in a Kotlin implementation. It requires as mentioned above windowsSoftInput="adjustResize" in the manifest:
class KeyboardWatcher(private val layoutRooView: View) {
companion object {
private const val MIN_KEYBOARD_HEIGHT = 200f
}
private val displayMetrics: DisplayMetrics = layoutRooView.resources.displayMetrics
private var stateVisible = false
var observer: ((Boolean) -> Unit)? = null
init {
layoutRooView.viewTreeObserver.addOnGlobalLayoutListener {
val heightDiff = layoutRooView.rootView.height - layoutRooView.height
if (!stateVisible && heightDiff > dpToPx(MIN_KEYBOARD_HEIGHT)) {
stateVisible = true
observer?.invoke(stateVisible)
} else if(stateVisible) {
stateVisible = false
observer?.invoke(stateVisible)
}
}
}
private fun dpToPx(valueInDp: Float): Float {
return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, valueInDp, displayMetrics)
}
}
And to use:
val activityRootView = findViewById<ViewGroup>(R.id.activityRoot)
KeyboardWatcher(activityRootView).observer = { visible ->
if (visible) do something here ...
}
You can find a few examples here:
// Fill the DataSet. DataSet ds = new DataSet(); ds.Locale = CultureInfo.InvariantCulture; FillDataSet(ds); DataTable contacts = ds.Tables["Contact"]; DataTable orders = ds.Tables["SalesOrderHeader"]; var query = contacts.AsEnumerable().Join(orders.AsEnumerable(), order => order.Field<Int32>("ContactID"), contact => contact.Field<Int32>("ContactID"), (contact, order) => new { ContactID = contact.Field<Int32>("ContactID"), SalesOrderID = order.Field<Int32>("SalesOrderID"), FirstName = contact.Field<string>("FirstName"), Lastname = contact.Field<string>("Lastname"), TotalDue = order.Field<decimal>("TotalDue") }); foreach (var contact_order in query) { Console.WriteLine("ContactID: {0} " + "SalesOrderID: {1} " + "FirstName: {2} " + "Lastname: {3} " + "TotalDue: {4}", contact_order.ContactID, contact_order.SalesOrderID, contact_order.FirstName, contact_order.Lastname, contact_order.TotalDue); }

In my sign_in.xml
file I used this:
<Button
android:id="@+id/signuptextlinkbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:background="@android:color/transparent"
android:onClick="performSingUpMethod"
android:text="Sign up now!"
android:textColor="#5B55FF"
android:textSize="15dp"
android:textStyle="bold" />
In my SignIn.java
file, I used this:
import android.graphics.Paint;
Button signuptextlinkbutton = (Button) findViewById(R.id.signuptextlinkbtn);
signuptextlinkbutton.setPaintFlags(signuptextlinkbutton.getPaintFlags()| Paint.UNDERLINE_TEXT_FLAG);
Now I can see my link underlined. It was simply text even thought I declared it as a Button

Converting a 4-byte array into integer:
//Explictly declaring anInt=-4, byte-by-byte
byte[] anInt = {(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xfc}; // Equals -4
//And now you have a 4-byte array with an integer equaling -4...
//Converting back to integer from 4-bytes...
result = (int) ( anInt[0]<<24 | ( (anInt[1]<<24)>>>8 ) | ( (anInt[2]<<24)>>>16) | ( (anInt[3]<<24)>>>24) );
I saw this error when my header file was missing closing brackets.
Causing this error:
// Obj.h
class Obj {
public:
Obj();
Fixing this error:
// Obj.h
class Obj {
public:
Obj();
};
what u can also do i place an extra "dummy" div before your last div.
Make it 1 px heigh and the width as much needed to cover the container div/body
This will make the last div appear under it, starting from the left.
See ?boxplot
for all the help you need.
outline: if ‘outline’ is not true, the outliers are not drawn (as
points whereas S+ uses lines).
boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)
And for extending the range of the whiskers and suppressing the outliers inside this range:
range: this determines how far the plot whiskers extend out from the
box. If ‘range’ is positive, the whiskers extend to the most
extreme data point which is no more than ‘range’ times the
interquartile range from the box. A value of zero causes the
whiskers to extend to the data extremes.
# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)
There are five ways to output text to the console:
Dim StdOut : Set StdOut = CreateObject("Scripting.FileSystemObject").GetStandardStream(1)
WScript.Echo "Hello"
WScript.StdOut.Write "Hello"
WScript.StdOut.WriteLine "Hello"
Stdout.WriteLine "Hello"
Stdout.Write "Hello"
WScript.Echo will output to console but only if the script is started using cscript.exe. It will output to message boxes if started using wscript.exe.
WScript.StdOut.Write and WScript.StdOut.WriteLine will always output to console.
StdOut.Write and StdOut.WriteLine will also always output to console. It requires extra object creation but it is about 10% faster than WScript.Echo.
A little optimization of the class before. In this version the files are not totally loaded into memory.

Use the following code it worked for me:
# Create the figure
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
# Generate the values
x_vals = X_iso[:, 0:1]
y_vals = X_iso[:, 1:2]
z_vals = X_iso[:, 2:3]
# Plot the values
ax.scatter(x_vals, y_vals, z_vals, c = 'b', marker='o')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')
plt.show()
while X_iso is my 3-D array and for X_vals, Y_vals, Z_vals I copied/used 1 column/axis from that array and assigned to those variables/arrays respectively.
Won't work for every, but this just saved me a bunch of time. I just had the problem with a CSV returning "TRUE or "FALSE" so I just added VALUE.to_s.downcase == "true" which will return the boolean true if the value is "TRUE" and false if the value is "FALSE", but will still work for the boolean true and false.
As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).
On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.
You can check awesome material design components for AngularJS:

How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou
Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?

This loops through column A of sheet1 and creates a formula in sheet2 for every cell. To find the last cell in Sheet1, I start at the bottom (shSource.Rows.Count) and .End(xlUp) to get the last cell in the column that's not blank.
To create the elements of the formula, I use the Address property of the cell on Sheet. I'm using three of the arguments to Address. The first two are RowAbsolute and ColumnAbsolute, both set to false. I don't care about the third argument, but I set the fourth argument (External) to True so that it includes the sheet name.
I prefer to go from Source to Destination rather than the other way. But that's just a personal preference. If you want to work from the destination,
Sub Results3()
Dim i As Long, lCnt As Long

lCnt = Application.WorksheetFunction.CountA(ThisWorkbook.Sheets("Sheet1").Columns(1))

The answer by Steve Jessop explains well, why you can't use std::map::operator[]
on a const std::map
. Gabe Rainbow's answer suggests a nice alternative. I'd just like to provide some example code on how to use map::at()
. So, here is an enhanced example of your function()
:
void function(const MAP &map, const std::string &findMe) {
try {
const std::string& value = map.at(findMe);
std::cout << "Value of key \"" << findMe.c_str() << "\": " << value.c_str() << std::endl;
// TODO: Handle the element found.
}
catch (const std::out_of_range&) {
std::cout << "Key \"" << findMe.c_str() << "\" not found" << std::endl;
// TODO: Deal with the missing element.
}
}
And here is an example main()
function:
int main() {
MAP valueMap;
valueMap["string"] = "abc";
function(valueMap, "string");
function(valueMap, "strong");
return 0;
}
Output:
Value of key "string": abc
Key "strong" not found
You are specifically asking about how they internally work, so here you are:
private int counter;
public int getNextUniqueIndex() {
return counter++;
}
It basically reads value from memory, increments it and puts back to memory. This works in single thread but nowadays, in the era of multi-core, multi-CPU, multi-level caches it won't work correctly. First of all it introduces race condition (several threads can read the value at the same time), but also visibility problems. The value might only be stored in "local" CPU memory (some cache) and not be visible for other CPUs/cores (and thus - threads). This is why many refer to local copy of a variable in a thread. It is very unsafe. Consider this popular but broken thread-stopping code:
private boolean stopped;
public void run() {
while(!stopped) {
//do some work
}
}
public void pleaseStop() {
stopped = true;
}
Add volatile
to stopped
variable and it works fine - if any other thread modifies stopped
variable via pleaseStop()
method, you are guaranteed to see that change immediately in working thread's while(!stopped)
loop. BTW this is not a good way to interrupt a thread either, see: How to stop a thread that is running forever without any use and Stopping a specific java thread.
AtomicInteger
private AtomicInteger counter = new AtomicInteger();
public int getNextUniqueIndex() {
return counter.getAndIncrement();
}
The AtomicInteger
class uses CAS (compare-and-swap) low-level CPU operations (no synchronization needed!) They allow you to modify a particular variable only if the present value is equal to something else (and is returned successfully). So when you execute getAndIncrement()
it actually runs in a loop (simplified real implementation):
int current;
do {
current = get();
} while(!compareAndSet(current, current + 1));
So basically: read; try to store incremented value; if not successful (the value is no longer equal to current
), read and try again. The compareAndSet()
is implemented in native code (assembly).
volatile
without synchronizationprivate volatile int counter;
public int getNextUniqueIndex() {
return counter++;
}
This code is not correct. It fixes the visibility issue (volatile
makes sure other threads can see change made to counter
) but still has a race condition. This has been explained multiple times: pre/post-incrementation is not atomic.
The only side effect of volatile
is "flushing" caches so that all other parties see the freshest version of the data. This is too strict in most situations; that is why volatile
is not default.
volatile
without synchronization (2)volatile int i = 0;
void incIBy5() {
i += 5;
}
The same problem as above, but even worse because i
is not private
. The race condition is still present. Why is it a problem? If, say, two threads run this code simultaneously, the output might be + 5
or + 10
. However, you are guaranteed to see the change.
synchronized
void incIBy5() {
int temp;
synchronized(i) { temp = i }
synchronized(i) { i = temp + 5 }
}
Surprise, this code is incorrect as well. In fact, it is completely wrong. First of all you are synchronizing on i
, which is about to be changed (moreover, i
is a primitive, so I guess you are synchronizing on a temporary Integer
created via autoboxing...) Completely flawed. You could also write:
synchronized(new Object()) {
//thread-safe, SRSLy?
}
No two threads can enter the same synchronized
block with the same lock. In this case (and similarly in your code) the lock object changes upon every execution, so synchronized
effectively has no effect.
Even if you have used a final variable (or this
) for synchronization, the code is still incorrect. Two threads can first read i
to temp
synchronously (having the same value locally in temp
), then the first assigns a new value to i
(say, from 1 to 6) and the other one does the same thing (from 1 to 6).
The synchronization must span from reading to assigning a value. Your first synchronization has no effect (reading an int
is atomic) and the second as well. In my opinion, these are the correct forms:
void synchronized incIBy5() {
i += 5
}
void incIBy5() {
synchronized(this) {
i += 5
}
}
void incIBy5() {
synchronized(this) {
int temp = i;
i = temp + 5;
}
}

</div>
.blogwidevideo {
overflow:hidden;
padding-bottom:56.25%;
position:relative;
height:0;
}
.blogwidevideo iframe {
left:10%; //centers for the 80% width - not needed if width is 100%
top:0;
height:80%; //change to 100% if going full width
width:80%;
position:absolute;
}
That's because the return type for [data bytes] is a void* c-style array, not a Uint8 (which is what Byte is a typedef for).
The error is because you are trying to set an allocated array when the return is a pointer type, what you are looking for is the getBytes:length: call which would look like:
[data getBytes:&byteData length:len];
Which fills the array you have allocated with data from the NSData object.
You can do this more easy way. And 100% works that you want

var i;
for (i=0; i < arr.length; i++) {

return;

}

var i;
for (i=0; i < arr.length; i++) {

return;
}
}
});
},
function() {
// Output content of page to stdout after form has been submitted
page.evaluate(function() {
console.log(document.querySelectorAll('html')[0].outerHTML);
});
}
];
interval = setInterval(function() {
if (!loadInProgress && typeof steps[testindex] == "function") {
console.log("step " + (testindex + 1));

From ?read.table
: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.
So, perhaps your data file isn't clean. Being more specific will help the data import:
d = read.table("foobar.txt",
sep="\t",
col.names=c("id", "name"),
fill=FALSE,
strip.white=TRUE)
will specify exact columns and fill=FALSE
will force a two column data frame.

let its required n bit then 2^n=(base)^digit and then take log and count no. for n
To mock a static method that return void for e.g. Fileutils.forceMKdir(File file),
Sample code:
File file =PowerMockito.mock(File.class);
PowerMockito.doNothing().when(FileUtils.class,"forceMkdir",file);
The simple and basic way (guzzle6):
$client = new Client([
'headers' => [ 'Content-Type' => 'application/json' ]
]);
$response = $client->post('http://api.com/CheckItOutNow',
['body' => json_encode(
[
'hello' => 'World'
]
)]
);
To get the response status code and the content of the body I did this:
echo '<pre>' . var_export($response->getStatusCode(), true) . '</pre>';
echo '<pre>' . var_export($response->getBody()->getContents(), true) . '</pre>';
Another possibility would be to set the Working Directory
under the debugging options to be the directory that has that DLL.
Edit: I was going to mention using a batch file to start Visual Studio (and set the PATH variable in the batch file). So then did a bit of searching and see that this exact same question was asked not long ago in this post. The answer suggests the batch file option as well as project settings that apparently may do the job (I did not test it).
Take a look at this post on Java Ranch:
http://www.coderanch.com/t/300287/JDBC/java/Io-Exception-Network-Adapter-could
"The solution for my "Io exception: The Network Adapter could not establish the connection" exception was to replace the IP of the database server to the DNS name."
There are a lot of good answers here already. But for me it was hard to find some example, where the shape or array can break all the program.
So here is the one:
import numpy as np
a = np.array([1,2,3,4])
b = np.array([10,20,30,40])
from sklearn.linear_model import LinearRegression
regr = LinearRegression()
regr.fit(a,b)
This will fail with error:
ValueError: Expected 2D array, got 1D array instead
but if we add reshape
to a
:
a = np.array([1,2,3,4]).reshape(-1,1)
this works correctly!
As far as I know there is not "an IDE" for Django, but there are some IDEs that support Django right out of the box, specifically the Django syntax for templates.
The name is Komodo, and it has a lot of features, but it's not cheap. If you are not worried about source control or debugging then there is a free version called Komodo Edit.
This is an old post but I just run to the same problem on AWS EC2 installing regex. This working perfectly for me
sudo yum -y install gcc
and next
sudo yum -y install gcc-c++
This is how I manage to handle it:
const decbin = nbr => {
if(nbr < 0){
nbr = 0xFFFFFFFF + nbr + 1
}
return parseInt(nbr, 10).toString(2)
};
got it from this link: https://locutus.io/php/math/decbin/
Adobe Illustrator uses bezier curves like SVG, and for circles it creates four points. You can create a circle with two elliptical arc commands...but then for a circle in SVG I would use a <circle />
:)
Make sure your project is 32 bit.
I had this problem, as soon as I ticked "Prefer 32 bit and rebuilt" all the Office Interop assemblies where available in Reference->Assemblies->Search "Office".
To find IP address list I have used this solution
public static IEnumerable<string> GetAddresses()
{
var host = Dns.GetHostEntry(Dns.GetHostName());
return (from ip in host.AddressList where ip.AddressFamily == AddressFamily.lo select ip.ToString()).ToList();
}
But I personally like below solution to get local valid IP address
public static IPAddress GetIPAddress(string hostName)
{
Ping ping = new Ping();
var replay = ping.Send(hostName);
if (replay.Status == IPStatus.Success)
{
return replay.Address;
}
return null;
}
public static void Main()
{
Console.WriteLine("Local IP Address: " + GetIPAddress(Dns.GetHostName()));
Console.WriteLine("Google IP:" + GetIPAddress("google.com");
Console.ReadLine();
}
>>> average = [1,3,2,1,1,0,24,23,7,2,727,2,7,68,7,83,2]
>>> matches = [i for i in range(0,len(average)) if average[i]<2 or average[i]>4]
>>> matches
[0, 3, 4, 5, 6, 7, 8, 10, 12, 13, 14, 15]

1-usual ctor, 2nd-function-like-ctor with temporary object.
Compile this source somewhere here http://melpon.org/wandbox/ with different compilers
// turn off rvo for clang, gcc with '-fno-elide-constructors'
#include <stdio.h>
class Thing {
public:
Thing(const char*){puts(__FUNCTION__ );}
Thing(const Thing&){puts(__FUNCTION__ );}
~Thing(){puts(__FUNCTION__);}
};
int main(int /*argc*/, const char** /*argv*/) {
Thing myThing = Thing("asdf");
}
And you will see the result.
From ISO/IEC 14882 2003-10-15
8.5, part 12
Your 1st,2nd construction are called direct-initialization
12.1, part 13
A functional notation type conversion (5.2.3) can be used to create new objects of its type. [Note: The syntax looks like an explicit call of the constructor. ] ... An object created in this way is unnamed. [Note: 12.2 describes the lifetime of temporary objects. ] [Note: explicit constructor calls do not yield lvalues, see 3.10. ]
Where to read about RVO:
12 Special member functions / 12.8 Copying class objects/ Part 15
When certain criteria are met, an implementation is allowed to omit the copy construction of a class object, even if the copy constructor and/or destructor for the object have side effects.
Turn off it with compiler flag from comment to view such copy-behavior)
Lots of good answers here, just out of curiosity after looking into this today, is it not best to use setInterval
rather than the setTimeout
?
setInterval(function() {
location.reload();
}, 30000);
let me know you thoughts.
Looking at the source code for dumpsys and service, you can get the list of services available by executing the following:
adb shell service -l
You can then supply the service name you are interested in to dumpsys to get the specific information. For example (note that not all services provide dump info):
adb shell dumpsys activity
adb shell dumpsys cpuinfo
adb shell dumpsys battery
As you can see in the code (and in K_Anas's answer), if you call dumpsys without any service name, it will dump the info on all services in one big dump:
adb shell dumpsys
Some services can receive additional arguments on what to show which normally is explained if you supplied a -h
argument, for example:
adb shell dumpsys activity -h
adb shell dumpsys window -h
adb shell dumpsys meminfo -h
adb shell dumpsys package -h
adb shell dumpsys batteryinfo -h
I had much better luck testing locally using 127.0.0.1 as the domain. I'm not sure why, but I had mixed results with localhost and .localhost, etc.
The concatenation operator +
is a binary infix operator which, when applied to lists, returns a new list containing all the elements of each of its two operands. The list.append()
method is a mutator
on list
which appends its single object
argument (in your specific example the list c
) to the subject list
. In your example this results in c
appending a reference to itself (hence the infinite recursion).
The list.extend()
method is also a mutator method which concatenates its sequence
argument with the subject list
. Specifically, it appends each of the elements of sequence
in iteration order.
Being an operator, +
returns the result of the expression as a new value. Being a non-chaining mutator
method, list.extend()
modifies the subject list in-place and returns nothing.
I've added this due to the potential confusion which the Abel's answer above may cause by mixing the discussion of lists, sequences and arrays.
Arrays
were added to Python after sequences and lists, as a more efficient way of storing arrays of integral data types. Do not confuse arrays
with lists
. They are not the same.
From the array docs:
Arrays are sequence types and behave very much like lists, except that the type of objects stored in them is constrained. The type is specified at object creation time by using a type code, which is a single character.
just use UPDATE query without condition like this
UPDATE tablename SET online_status=0;
In my case the IP address of our git host had changed.
Simply flushing the DNS cache fixed the problem.
If the bytes use an appropriate character encoding already; you could print them directly:
sys.stdout.buffer.write(data)
or
nwritten = os.write(sys.stdout.fileno(), data) # NOTE: it may write less than len(data) bytes
One important issue with long polling is error handling. There are two types of errors:
The request might timeout in which case the client should reestablish the connection immediately. This is a normal event in long polling when no messages have arrived.
A network error or an execution error. This is an actual error which the client should gracefully accept and wait for the server to come back on-line.
The main issue is that if your error handler reestablishes the connection immediately also for a type 2 error, the clients would DOS the server.
Both answers with code sample miss this.
function longPoll() {
var shouldDelay = false;
$.ajax({
url: 'poll.php',
async: true, // by default, it's async, but...
dataType: 'json', // or the dataType you are working with
timeout: 10000, // IMPORTANT! this is a 10 seconds timeout
cache: false
}).done(function (data, textStatus, jqXHR) {
// do something with data...
}).fail(function (jqXHR, textStatus, errorThrown ) {
shouldDelay = textStatus !== "timeout";
}).always(function() {
// in case of network error. throttle otherwise we DOS ourselves. If it was a timeout, its normal operation. go again.
var delay = shouldDelay ? 10000: 0;
window.setTimeout(longPoll, delay);
});
}
longPoll(); //fire first handler
When you use df.apply()
, each row of your DataFrame will be passed to your lambda function as a pandas Series. The frame's columns will then be the index of the series and you can access values using series[label]
.
So this should work:
df['D'] = (df.apply(lambda x: myfunc(x[colNames[0]], x[colNames[1]]), axis=1))
Best solution: Don't use global
s
>>> test1 = 0
>>> def test_func(x):
return x + 1
>>> test1 = test_func(test1)
>>> test1
1
Many people have posted a solution that's over-optimized. I don't think it is incorrect, but I humbly think that a less optimized solution will be desirable to permit everyone to easily understand how is this working. Here is my proposal:
#!/bin/bash
#
# This program reads lines from a file.
#
end_of_file=0
while [[ $end_of_file == 0 ]]; do
read -r line
# the last exit status is the
# flag of the end of file
end_of_file=$?
echo $line
done < "$1"
You might want to remove the accents and diacritic signs first, then on each character position check if the "simplified" string is an ascii letter - if it is, the original position shall contain word characters, if not, it can be removed.
You can also use <br/>
where you want to break the text.
As I can see: http://itsolutionstuff.com/post/laravel-5-clear-cache-from-route-view-config-and-all-cache-data-from-applicationexample.html
is it possible to use the code below with the new clear cache commands:
//Clear Cache facade value:
Route::get('/clear-cache', function() {
$exitCode = Artisan::call('cache:clear');
return '<h1>Cache facade value cleared</h1>';
});
//Reoptimized class loader:
Route::get('/optimize', function() {
$exitCode = Artisan::call('optimize');
return '<h1>Reoptimized class loader</h1>';
});
//Route cache:
Route::get('/route-cache', function() {
$exitCode = Artisan::call('route:cache');
return '<h1>Routes cached</h1>';
});
//Clear Route cache:
Route::get('/route-clear', function() {
$exitCode = Artisan::call('route:clear');
return '<h1>Route cache cleared</h1>';
});
//Clear View cache:
Route::get('/view-clear', function() {
$exitCode = Artisan::call('view:clear');
return '<h1>View cache cleared</h1>';
});
//Clear Config cache:
Route::get('/config-cache', function() {
$exitCode = Artisan::call('config:cache');
return '<h1>Clear Config cleared</h1>';
});
It's not necessary to give the possibility to clear the caches to everyone, especially in a production enviroment, so I suggest to comment that routes and, when it's needed, to de-comment the code and run the routes.
You will want to use interfaces. Generally, multiple inheritance is bad because of the Diamond Problem:
abstract class A {
abstract string foo();
}
class B extends A {
string foo () { return "bar"; }
}
class C extends A {
string foo() {return "baz"; }
}
class D extends B, C {
string foo() { return super.foo(); } //What do I do? Which method should I call?
}
C++ and others have a couple ways to solve this, eg
string foo() { return B::foo(); }
but Java only uses interfaces.
The Java Trails have a great introduction on interfaces: http://download.oracle.com/javase/tutorial/java/concepts/interface.html You'll probably want to follow that before diving into the nuances in the Android API.
