http://en.wikibooks.org/wiki/LaTeX/Tables#Resize_tables talks about two ways to do this.
I used:
\scalebox{0.7}{
\begin{tabular}
...
\end{tabular}
}
This is what I did:
\begin{frame}{series of images}
\begin{center}
\begin{overprint}
\only<2>{\includegraphics[scale=0.40]{image1.pdf}}
\hspace{-0.17em}\only<3>{\includegraphics[scale=0.40]{image2.pdf}}
\hspace{-0.34em}\only<4>{\includegraphics[scale=0.40]{image3.pdf}}
\hspace{-0.17em}\only<5>{\includegraphics[scale=0.40]{image4.pdf}}
\only<2-5>{\mbox{\structure{Figure:} something}}
\end{overprint}
\end{center}
\end{frame}
Just an update.
The present TiKZ package will issue: Package tikz Warning: Snakes have been superseded by decorations. Please use the decoration libraries instead of the snakes library on input line. . .
So the pertaining part of code has to be changed to:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations}
\begin{document}
\begin{tikzpicture}
%draw horizontal line
\draw (0,0) -- (2,0);
\draw[decorate,decoration={snake,pre length=5mm, post length=5mm}] (2,0) -- (4,0);
\draw (4,0) -- (5,0);
\draw[decorate,decoration={snake,pre length=5mm, post length=5mm}] (5,0) -- (7,0);
%draw vertical lines
\foreach \x in {0,1,2,4,5,7}
\draw (\x cm,3pt) -- (\x cm,-3pt);
%draw nodes
\draw (0,0) node[below=3pt] {$ 0 $} node[above=3pt] {$ $};
\draw (1,0) node[below=3pt] {$ 1 $} node[above=3pt] {$ 10 $};
\draw (2,0) node[below=3pt] {$ 2 $} node[above=3pt] {$ 20 $};
\draw (3,0) node[below=3pt] {$ $} node[above=3pt] {$ $};
\draw (4,0) node[below=3pt] {$ 5 $} node[above=3pt] {$ 50 $};
\draw (5,0) node[below=3pt] {$ 6 $} node[above=3pt] {$ 60 $};
\draw (6,0) node[below=3pt] {$ $} node[above=3pt] {$ $};
\draw (7,0) node[below=3pt] {$ n $} node[above=3pt] {$ 10n $};
\end{tikzpicture}
\end{document}
HTH
You may want to look at http://tug.ctan.org/tex-archive/macros/latex/contrib/float/ which allows you to define new floats using \newfloat
I say this because captions are usually applied to floats.
Straight ahead equations (those written with $ ... $
, $$ ... $$
, begin{equation}...
) are in-line objects that do not support \caption
.
This can be done using the following snippet just before \begin{document}
\usepackage{float}
\usepackage{aliascnt}
\newaliascnt{eqfloat}{equation}
\newfloat{eqfloat}{h}{eqflts}
\floatname{eqfloat}{Equation}
\newcommand*{\ORGeqfloat}{}
\let\ORGeqfloat\eqfloat
\def\eqfloat{%
\let\ORIGINALcaption\caption
\def\caption{%
\addtocounter{equation}{-1}%
\ORIGINALcaption
}%
\ORGeqfloat
}
and when adding an equation use something like
\begin{eqfloat}
\begin{equation}
f( x ) = ax + b
\label{eq:linear}
\end{equation}
\caption{Caption goes here}
\end{eqfloat}
The best way to do it without any headache is to use the
\tablefootnote
command from the tablefootnote
package. Add the following to your preamble:
\usepackage{tablefootnote}
It just works without the need of additional tricks.
You answered your own question---unsrt
is to be used when you want references to ne listed in the order of appeareance.
But you might also want to have a look at natbib, an extremely flexible citation package. I can not imagine living without it.
You should \usepackage{longtable}
.
try [h!] first but else you can do it the ugly way.
LateX is a bit hard in placing images with such constraints as it manages placing itself. What I usually do if I want a figure right in that spot is do something like|:
text in front of image here
\newpage
\figure1
\figure2
text after images here
I know it may not be the correct way to do it but it works like a charm :).
//edit
You can do the same if you want a little text at top of the page but then just use /clearpage. Of course you can also scale them a bit smaller so it does not happen anymore. Maybe the non-seen whitespace is a bit larger than you suspect, I always try to scale down my image until they do appear on the same page, just to know for sure there is not like 1% overlap only making all of this not needed.
You must place the label after a caption in order to for label
to store the table's number, not the chapter's number.
\begin{table} \begin{tabular}{| p{5cm} | p{5cm} | p{5cm} |} -- cut -- \end{tabular} \caption{My table} \label{table:kysymys} \end{table} Table \ref{table:kysymys} on page \pageref{table:kysymys} refers to the ...
The tabularx
package gives you
X
, all X
columns will grow to fill up the total width.For your example:
\usepackage{tabularx}
% ...
\begin{document}
% ...
\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF & simulation & jsp\\
\hline
\end{tabularx}
I have success with using the Chrome addon "Sharelatex". This online editor has great compability with most latex files, but it somewhat lacks configuration possibilities. www.sharelatex.com
The cleanest way for you to accomplish this is to use the enumitem package (https://ctan.org/pkg/enumitem). For example,
\documentclass{article}
\usepackage{enumitem}% http://ctan.org/pkg/enumitem
\begin{document}
\noindent Here is some text and I want to make sure
there is no spacing the different items.
\begin{itemize}[noitemsep]
\item Item 1
\item Item 2
\item Item 3
\end{itemize}
\noindent Here is some text and I want to make sure
there is no spacing between this line and the item
list below it.
\begin{itemize}[noitemsep,topsep=0pt]
\item Item 1
\item Item 2
\item Item 3
\end{itemize}
\end{document}
Furthermore, if you want to use this setting globally across lists, you can use
\usepackage{enumitem}% http://ctan.org/pkg/enumitem
\setlist[itemize]{noitemsep, topsep=0pt}
However, note that this package does not work well with the beamer package which is used to make presentations in Latex.
LaTeX comes with most Linux distributions in the form of the teTeX distribution. Find all packages with 'teTeX' in the name and install them.
Most editors such as vim or emacs come with TeX editing modes. You can also get WYSIWIG-ish front-ends (technically WYSIWYM), of which perhaps the best known is LyX.
The best quick intro to LaTeX is Oetiker's 'The not so short intro to LaTeX'
LaTeX works like a compiler. You compile the LaTeX document (which can include other files), which generates a file called a .dvi
(device independent). This can be post-processed to various formats (including PDF) with various post-processors.
To do PDF, use dvips
and use the flag -PPDF (IIRC - I don't have a makefile to hand) to produce a PS with font rendering set up for conversion to pdf. PDF conversion can then be done with ps2pdf
or distiller (if you have this).
The best format for including graphics in this environment is eps
(Encapsulated Postscript) although not all software produces well-behaved postscript. Photographs in jpeg or other formats can be included using various mechanisms.
You can use \centering
with your parbox to do this.
(Sorry for the Google cached link; the original one I had doesn't work anymore.)
You can also use \openany
, \openright
and \openleft
commands:
\documentclass{memoir}
\begin{document}
\openany
\appendix
\openright
\appendixpage
This is the appendix.
\end{document}
The use of the package \usepackage{fancyvrb}
allows the definition of the fontsize argument inside Verbatim:
\begin{Verbatim}[fontsize=\small]
print "Hello, World"
\end{Verbatim}
The fontsize that you can specify are the common
\tiny
\scriptsize
\footnotesize
\small
\normalsize
\large
\Large
\LARGE
\huge
\Huge
I found the better control would be using scalefnt package:
\usepackage{scalefnt}
...
{\scalefont{0.5}
\begin{tikzpicture}
...
\end{tikzpicture}
}
I think you can simply add the oneside option the book class?
i.e.
\documentclass[oneside]{book}
Although I didn't test it :)
On a Mac (pdftex) I managed to include a png file simply with \includegraphics[width=1.2\textwidth]{filename.png}. But in order for that to work I had to comment out the following 2 packages:
%\usepackage[dvips]{epsfig}
%\usepackage[dvips]{graphicx}
...and simply use package graphicx:
\usepackage{graphicx}
It seems [dvips] is problematic when used with pdftex.
The first line of a paragraph is indented by default, thus whether or not you have \indent
there won't make a difference. \indent
and \noindent
can be used to override default behavior. You can see this by replacing your line with the following:
Now we are engaged in a great civil war.\\
\indent this is indented\\
this isn't indented
\noindent override default indentation (not indented)\\
asdf
You can use these options as well, either use \footnotesize
or \tiny
. This would really help in fitting big tables.
\begin{table}[htbp]
\footnotesize
\caption{Information on making the table size small}
\label{table:table1}
\begin{tabular}{ll}
\toprule
S.No & HMD \\
\midrule
1 & HTC Vive \\
2 & HTC Vive Pro \\
\bottomrule
\end{tabular}
\end{table}
Use Minted.
It's a package that facilitates expressive syntax highlighting in LaTeX using the powerful Pygments library. The package also provides options to customize the highlighted source code output using fancyvrb.
It's much more evolved and customizable than any other package!
if you add a jpg,png,pdf picture, you should use pdflatex to compile it.
Surround it with an \mbox{}
like this
\begin{align}
x_{\rm L} & = L \int{\cos\theta\left(\xi\right) d\xi}, \label{eq_1} \\\\
y_{\rm L} & = L \int{\sin\theta\left(\xi\right) d\xi}, \nonumber
\end{align}
Use \overleftarrow
to create a long arrow to the left.
\overleftarrow{blahblahblah}
You might find mimeTeX useful.
There is a pretty good list at linuxappfinder.com.
My personal preference for LaTeX on Linux has been the KDE-based editor Kile.
That can be achieve in plain LaTeX without any specific package.
\documentclass{article}
\begin{document}
This is your only binary choices
\begin{math}
\left\{
\begin{array}{l}
0\\
1
\end{array}
\right.
\end{math}
\end{document}
This code produces something which looks what you seems to need.
The same example as in the @Tombart can be obtained with similar code.
\documentclass{article}
\begin{document}
\begin{math}
f(x)=\left\{
\begin{array}{ll}
1, & \mbox{if $x<0$}.\\
0, & \mbox{otherwise}.
\end{array}
\right.
\end{math}
\end{document}
This code produces very similar results.
Below is an example of multiple figures that I used recently in Latex. You need to call these packages
\usepackage{graphicx}
\usepackage{subfig})
\begin{figure}[H]%
\centering
\subfloat[Row1]{{\includegraphics[scale=.36]{1.png} }}%
\subfloat[Row2]{{\includegraphics[scale=.36]{2.png} }}%
\subfloat[Row3]{{\includegraphics[scale=.36]{3.png} }}%
\hfill
\subfloat[Row4]{{\includegraphics[scale=0.37]{4.png} }}%
\subfloat[Row5]{{\includegraphics[scale=0.37]{5.png} }}%
\caption{Multiple figures in latex.}%
\label{fig:MFL}%
\end{figure}
You can import a csv file to this website(https://www.tablesgenerator.com/latex_tables) and click copy to clipboard.
What about using a tabular inside \author{}
, just like in IEEE macros:
\documentclass{article}
\begin{document}
\title{Hello, World}
\author{
\begin{tabular}[t]{c@{\extracolsep{8em}}c}
I. M. Author & M. Y. Coauthor \\
My Department & Coauthor Department \\
My Institute & Coauthor Institute \\
email, address & email, address
\end{tabular}
}
\maketitle
\end{document}
This will produce two columns authors with any documentclass
.
Results:
The @ sign means the file has extended attributes. xattr file
shows what attributes it has, xattr -l file
shows the attribute values too (which can be large sometimes — try e.g. xattr /System/Library/Fonts/HelveLTMM
to see an old-style font that exists in the resource fork).
Use the pdfpages
package.
\usepackage{pdfpages}
To include all the pages in the PDF file:
\includepdf[pages=-]{myfile.pdf}
To include just the first page of a PDF:
\includepdf[pages={1}]{myfile.pdf}
Run texdoc pdfpages
in a shell to see the complete manual for pdfpages
.
Thanks Joris for creating this question. Hopefully, it will be made into a community wiki.
The booktabs packages in latex produces nice looking tables. Here is a blog post on how to use xtable to create latex tables that use booktabs
I would also add the apsrtable
package to the mix as it produces nice looking regression tables.
Another Idea: Some of these packages (esp. memisc and apsrtable) allow easy extensions of the code to produce tables for different regression objects. One such example is the lme4 memisc code shown in the question. It might make sense to start a github repository to collect such code snippets, and over time maybe even add it to the memisc package. Any takers?
I found the solution thanks to the link in Vincent's answer.
\renewcommand{\familydefault}{\sfdefault}
This changes the default font family to sans-serif.
You can easily achieve what you want using the appendix
package. Here's a sample file that shows you how. The key is the titletoc
option when calling the package. It takes whatever value you've defined in \appendixname
and the default value is Appendix
.
\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents
\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
\chapter{Consectetur adipiscing elit}
\chapter{Mauris euismod}
\end{appendices}
\end{document}
The output looks like
At the beginning with the usepackage
definitions include:
\usepackage{placeins}
And before and after add:
\FloatBarrier
\begin{table}[h]
\begin{tabular}{llll}
....
\end{tabular}
\end{table}
\FloatBarrier
This places the table exactly where you want in the text.
Just before your "Content of the letter" line, add \thispagestyle{fancy}
and it should show the headers you defined. (It worked for me.)
Here's the full document that I used to test:
\documentclass[12pt]{letter}
\usepackage{fontspec}% font selecting commands
\usepackage{xunicode}% unicode character macros
\usepackage{xltxtra} % some fixes/extras
% page counting, header/footer
\usepackage{fancyhdr}
\usepackage{lastpage}
\pagestyle{fancy}
\lhead{\footnotesize \parbox{11cm}{Draft 1} }
\lfoot{\footnotesize \parbox{11cm}{\textit{2}}}
\cfoot{}
\rhead{\footnotesize 3}
\rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}}
\renewcommand{\headheight}{24pt}
\renewcommand{\footrulewidth}{0.4pt}
\usepackage{lipsum}% provides filler text
\begin{document}
\name{ Joe Laroo }
\signature{ Joe Laroo }
\begin{letter}{ To-Address }
\renewcommand{\today}{ February 16, 2009 }
\opening{ Opening }
\thispagestyle{fancy}% sets the current page style to 'fancy' -- must occur *after* \opening
\lipsum[1-10]% just dumps ten paragraphs of filler text
\closing{ Yours truly, }
\end{letter}
\end{document}
The \opening
command sets the page style to firstpage
or empty
, so you have to use \thispagestyle
after that command.
Try to use the fleqn
document class option.
\documentclass[fleqn]{article}
(See also http://en.wikibooks.org/wiki/LaTeX/Basics for a list of other options.)
All of the above show hard it can be to make a nice, flexible (or forbid an overloaded) function in LaTeX!!! (that TeX code looks like greek to me)
well, just to add my recent (albeit not as flexible) development, here's what I've recently used in my thesis doc, with
\usepackage{ifthen} % provides conditonals...
Start the command, with the "optional" command set blank by default:
\newcommand {\figHoriz} [4] [] {
I then have the macro set a temporary variable, \temp{}, differently depending on whether or not the optional argument is blank. This could be extended to any passed argument.
\ifthenelse { \equal {#1} {} } %if short caption not specified, use long caption (no slant)
{ \def\temp {\caption[#4]{\textsl{#4}}} } % if #1 == blank
{ \def\temp {\caption[#1]{\textsl{#4}}} } % else (not blank)
Then I run the macro using the \temp{} variable for the two cases. (Here it just sets the short-caption to equal the long caption if it wasn't specified by the user).
\begin{figure}[!]
\begin{center}
\includegraphics[width=350 pt]{#3}
\temp %see above for caption etc.
\label{#2}
\end{center}
\end{figure}
}
In this case I only check for the single, "optional" argument that \newcommand{} provides. If you were to set it up for, say, 3 "optional" args, you'd still have to send the 3 blank args... eg.
\MyCommand {first arg} {} {} {}
which is pretty silly, I know, but that's about as far as I'm going to go with LaTeX - it's just not that sensical once I start looking at TeX code... I do like Mr. Robertson's xparse method though, perhaps I'll try it...
You can use the listings package. It supports many different languages and there are lots of options for customising the output.
\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[language=html]
<html>
<head>
<title>Hello</title>
</head>
<body>Hello</body>
</html>
\end{lstlisting}
\end{document}
How about something like:
\documentclass{article}
\usepackage{amssymb,amsmath}
\begin{document}
\begin{equation}\label{A_Label}
\begin{split}
w^T x_i + b \geqslant 1-\xi_i \text{ if } y_i &= 1, \\
w^T x_i + b \leqslant -1+\xi_i \text{ if } y_i &= -1
\end{split}
\end{equation}
\end{document}
which produces:
Use p{width} for your column specifiers instead of l/r/c.
\begin{tabular}{|p{1cm}|p{3cm}|}
This text will be wrapped & Some more text \\
\end{tabular}
EDIT: (based on the comments)
\begin{table}[ht]
\centering
\begin{tabular}{p{0.35\linewidth} | p{0.6\linewidth}}
Column 1 & Column2 \\ \hline
This text will be wrapped & Some more text \\
Some text here & This text maybe wrapped here if its tooooo long \\
\end{tabular}
\caption{Caption}
\label{tab:my_label}
\end{table}
we get:
Setting \itemindent
for a new itemize environment solves the problem:
\newenvironment{beameritemize}
{ \begin{itemize}
\setlength{\itemsep}{1.5ex}
\setlength{\parskip}{0pt}
\setlength{\parsep}{0pt}
\addtolength{\itemindent}{-2em} }
{ \end{itemize} }
I wrote how to write LaTeX in Jupyter Notebook in this article.
You need to enclose them in dollar($) signs.
$P(A)=\frac{n(A)}{n(U)}$
$$P(A)=\frac{n(A)}{n(U)}$$
Use \limits
for \lim
, \sum
and \int
to add limits to the top and the bottom of each sign.
Use a backslash to escape LaTeX special words such as Math symbols, Latin words, text, etc.
Try this one.
$$\overline{x}=\frac{\sum \limits _{i=1} ^k f_i x_i}{n} \text{, where } n=\sum \limits _{i=1} ^k f_i $$
$$
\begin{align}
\text{Probability density function:}\\
\begin{cases}
\frac{1}{b-a}&\text{for $x\in[a,b]$}\\
0&\text{otherwise}\\
\end{cases}
\\
\text{Cumulative distribution function:}\\
\begin{cases}
0&\text{for $x<a$}\\
\frac{x-a}{b-a}&\text{for $x\in[a,b)$}\\
1&\text{for $x\ge b$}\\
\end{cases}
\end{align}
$$
The above code will create this.
If you want to know how to add numbering to equations and align equations, please read this article for details.
You can also reset page number counter:
\setcounter{page}{1}
However, with this technique you get wrong page numbers in Acrobat in the top left page numbers field:
\maketitle: 1
\tableofcontents: 2
\setcounter{page}{1}
\section{Introduction}: 1
...
Using the multicol package and embedding your list in a multicols
environment does what you want:
\documentclass{article}
\usepackage{multicol}
\begin{document}
\begin{multicols}{2}
\begin{enumerate}
\item a
\item b
\item c
\item d
\item e
\item f
\end{enumerate}
\end{multicols}
\end{document}
I could not find a easy way to set the margin for a single page.
My solution was to use vspace with the number of centimeters of empty space I wanted:
\vspace*{5cm}
I put this command at the beginning of the pages that I wanted to have +5cm of margin.
Another option is to use \dfrac instead of \frac, which makes the whole fraction larger and hence more readable.
And no, I don't know if there is an option to get something in between \frac and \dfrac, sorry.
The question specifically mentions a full box and not an empty box and not using proof
environment from amsthm
package. Hence, an option may be to use the command \QED
from the package stix
. It reproduces the character U+220E
(end of proof, ?).
I am using texmaker as the editor. you have to compile it in terminal as following:
but sometimes, when you use \citep{}
, the names of the references don't show up. In this case, I had to open the references.bib
file , so that texmaker could capture the references from the references.bib file. After every edition of the bib file, I had to close and reopen it!! So that texmaker could capture the content of new .bbl file each time. But remember, you have to also run your code in texmaker too.
multi-disciplinary
will not be hyphenated, as explained by kennytm. But multi-\-disciplinary
has the same hyphenation opportunities that multidisciplinary
has.
I admit that I don't know why this works. It is different from the behaviour described here (emphasis mine):
The command
\-
inserts a discretionary hyphen into a word. This also becomes the only point where hyphenation is allowed in this word.
Yes, include float package into the top of your document and H (capital H) as a figure specifier:
\usepackage{float}
\begin{figure}[H]
.
.
.
\end{figure}
Have a try on the listings
package. Here is an example of what I used some time ago to have a coloured Java listing:
\usepackage{listings}
[...]
\lstset{language=Java,captionpos=b,tabsize=3,frame=lines,keywordstyle=\color{blue},commentstyle=\color{darkgreen},stringstyle=\color{red},numbers=left,numberstyle=\tiny,numbersep=5pt,breaklines=true,showstringspaces=false,basicstyle=\footnotesize,emph={label}}
[...]
\begin{lstlisting}
public void here() {
goes().the().code()
}
[...]
\end{lstlisting}
You may want to customize that. There are several references of the listings package. Just google them.
I just had the situation that I wanted this only for lines exceeding \linewidth
, that is: Squeezing long lines slightly.
Since it took me hours to figure this out, I would like to add it here.
I want to emphasize that scaling fonts in LaTeX is a deadly sin! In nearly every situation, there is a better way (e.g.
multline
of themathtools
package). So use it conscious.
In this particular case, I had no influence on the code base apart the preamble and some lines slightly overshooting the page border when I compiled it as an eBook-scaled pdf.
\usepackage{environ} % provides \BODY
\usepackage{etoolbox} % provides \ifdimcomp
\usepackage{graphicx} % provides \resizebox
\newlength{\myl}
\let\origequation=\equation
\let\origendequation=\endequation
\RenewEnviron{equation}{
\settowidth{\myl}{$\BODY$} % calculate width and save as \myl
\origequation
\ifdimcomp{\the\linewidth}{>}{\the\myl}
{\ensuremath{\BODY}} % True
{\resizebox{\linewidth}{!}{\ensuremath{\BODY}}} % False
\origendequation
}
You just need to escape characters that have special meaning: # $ % & ~ _ ^ \ { }
So
http://stack_overflow.com/~foo%20bar#link
would be
http://stack\_overflow.com/\~foo\%20bar\#link
The listings package is quite nice and very flexible (e.g. different sizes for comments and code).
For variables describing distances, you would use \newlength
(and manipulate the values with \setlength
, \addlength
, \settoheight
, \settolength
and \settodepth
).
Similarly you have access to \newcounter
for things like section and figure numbers which should increment throughout the document. I've used this one in the past to provide code samples that were numbered separatly of other figures...
Also of note is \makebox
which allows you to store a bit of laid-out document for later re-use (and for use with \settolength
...).
My first guess is that LaTeX chokes on | outside a math environment. Missing $ inserted is usually a symptom of something like that.
I have used graphviz ( https://www.graphviz.org/gallery ) together with LaTeX using dot command to generate graphs in PDF and includegraphics
to include those.
If graphviz produces what you are aiming at, this might be the best way to integrate: dot2tex: https://ctan.org/pkg/dot2tex?lang=en
This question was already asked on https://tex.stackexchange.com/questions/10684/vertical-space-in-lists. The highest voted answer also mentioned the enumitem
package (here answered by Stefan), but I also like this one, which involves creating your own itemizing environment instead of loading a new package:
\newenvironment{myitemize}
{ \begin{itemize}
\setlength{\itemsep}{0pt}
\setlength{\parskip}{0pt}
\setlength{\parsep}{0pt} }
{ \end{itemize} }
Which should be used like this:
\begin{myitemize}
\item one
\item two
\item three
\end{myitemize}
Insert some vertical space
blah blah blah \\
\vspace{1cm}
to scale to the font, use ex
(the height of a lowercase "x") as the unit, and there are various predefined lengths related to the line spacing available, you might be particularly interested in baselineskip
.
There are a couple ways you can deal with this. First, and perhaps best, is to rework your equation so that it is not so long; it is likely unreadable if it is that long.
If it must be so, check out the AMS Short Math Guide for some ways to handle it. (on the second page)
Personally, I'd use an align environment, so that the breaking and alignment can be precisely controlled. e.g.
\begin{align*}
x&+y+\dots+\dots+x_100000000\\
&+x_100000001+\dots+\dots
\end{align*}
which would line up the first plus signs of each line... but obviously, you can set the alignments wherever you like.
Using the hyperref
package, you could also declare a new command by using \newcommand{\secref}[1]{\autoref{#1}. \nameref{#1}}
in the pre-amble. Placing \secref{section:my}

Font Squirrel has a wonderful web font generator.
I think you should find what you need here to generate OTF fonts and the needed CSS to use them. It will even support older IE versions.
If I understand you, you can do it with a datetime.timedelta
-
import datetime
endTime = datetime.datetime.now() + datetime.timedelta(minutes=15)
while True:
if datetime.datetime.now() >= endTime:

This worked for me and was as easy as adding a gradle dependancy:
https://bintray.com/seesaa/maven/opencv#
https://github.com/seesaa/opencv-android
The one caveat being that I had to use a hardware debugging device as arm emulators were running too slow for me (as AVD Manager says they will), and, as described at the repo README, this version does not include x86 or x86_64 support.
It seems to build and the suggested test:
static {
OpenCVLoader.initDebug();
}
spits out a bunch of output that looks about right to me.
Please try the following code below:
//Here I am using a reader object to fetch data from database, along with sqlcommand onject (cmd).
//Once the data is loaded to the Datatable object (datatable) you can loop through it using the datatable.rows.count prop.
using (reader = cmd.ExecuteReader())
{
// Load the Data table object
dataTable.Load(reader);
if (dataTable.Rows.Count > 0)
{
DataColumn col = dataTable.Columns["YourColumnName"];
foreach (DataRow row in dataTable.Rows)
{
strJsonData = row[col].ToString();
}
}
}
npm start
will run whatever you have defined for the start
command of the scripts
object in your package.json
file.
So if it looks like this:
"scripts": {
"start": "ng serve"
}
Then npm start
will run ng serve
.
When I used --allow-unrelated-histories
, this command generated too many conflicts. There were conflicts in files which I didn't even work on. To get over the error " Refusing to merge unrelated histories"
, I used following rebase command:
git pull --rebase=preserve --allow-unrelated-histories
After this commit the uncommitted changes with a commit message. Finally, run the following command:
git rebase --continue
After this, my working copy was up-to-date with the remote copy and I was able to push my changes as before. No more unrelated histories error while pulling.
Using -s
option will print output of all functions, which may be too much.
If you need particular output, the doc page you mentioned offers few suggestions:
Insert assert False, "dumb assert to make PyTest print my stuff"
at the end of your function, and you will see your output due to failed test.
You have special object passed to you by PyTest, and you can write the output into a file to inspect it later, like
def test_good1(capsys):
for i in range(5):
print i
out, err = capsys.readouterr()
open("err.txt", "w").write(err)
open("out.txt", "w").write(out)
You can open the out
and err
files in a separate tab and let editor automatically refresh it for you, or do a simple py.test; cat out.txt
shell command to run your test.
That is rather hackish way to do stuff, but may be it is the stuff you need: after all, TDD means you mess with stuff and leave it clean and silent when it's ready :-).
You can use a constructor with no parameters in your Parent class :
public parent() { }
Using ddl.Items.Clear()
will clear the dropdownlist however you must be sure that your dropdownlist is not set to:
AppendDataBoundItems="True"
This option will cause the rebound data to be appended to the existing list which will NOT be cleared prior to binding.
SOLUTION
Add AppendDataBoundItems="False"
to your dropdownlist.
Now when data is rebound it will automatically clear all existing data beforehand.
Protected Sub ddl1_SelectedIndexChanged(sender As Object, e As EventArgs)
ddl2.DataSource = sql2
ddl2.DataBind()
End Sub
NOTE: This may not be suitable in all situations as appenddatbound items can cause your dropdown to append its own data on each change of the list.
TOP TIP
Still want a default list item adding to your dropdown but need to rebind data?
Use AppendDataBoundItems="False"
to prevent duplication data on postback and then directly after binding your dropdownlist insert a new default list item.
ddl.Items.Insert(0, New ListItem("Select ...", ""))

The highly regarded Joda Time library is also worth a look. This is basis for the new date and time api that is pencilled in for Java 7. The design is neat, intuitive, well documented and avoids a lot of the clumsiness of the original java.util.Date
/ java.util.Calendar
classes.
Joda's DateFormatter
can parse a String to a Joda DateTime

AppStore >> iosAPP >> Build (scroll down)
click the red icon as seen in the picture
I've had this double initialisation happen for a different reason. For some route-transitions in my application I wanted to force scrolling to near the top of the page (e.g. in paginated search results... clicking next should take you to the top of page 2).
I did this by adding a listener to the $rootScope
$on
$viewContentLoaded
which (based on certain conditions) executed
$location.hash('top');
Inadvertently this was causing my routes to be reevaluated and the controllers to be reinitialised
const static int newvals[] = {34,2,4,5,6};
std::copy(newvals, newvals+sizeof(newvals)/sizeof(newvals[0]), array);
In python 3, if you're using unittest.TestCase
:
__init__.py
file in your test
directory (must be named test/
)test/
match the pattern test_*.py
. They can be inside a subdirectory under test/
, and those subdirs can be named as anything.Then, you can run all the tests with:
python -m unittest
Done! A solution less than 100 lines. Hopefully another python beginner saves time by finding this.
In Eclipse, go to Window → Preferences → General → Network Connections. In the Active Provider combo box, choose "Manual". In the proxy entries table, for each entry click "Edit..." and supply your proxy host, port, username and password details.
Apple has changed the interface.
The team ID could be found via this link: https://developer.apple.com/account/#/membership
How about a service for services?
If we had an INamedService interface (with .Name property), we could write an IServiceCollection extension for .GetService(string name), where the extension would take that string parameter, and do a .GetServices() on itself, and in each returned instance, find the instance whose INamedService.Name matches the given name.
Like this:
public interface INamedService
{
string Name { get; }
}
public static T GetService<T>(this IServiceProvider provider, string serviceName)
where T : INamedService
{
var candidates = provider.GetServices<T>();
return candidates.FirstOrDefault(s => s.Name == serviceName);
}
Therefore, your IMyService must implement INamedService, but you'll get the key-based resolution you want, right?
To be fair, having to even have this INamedService interface seems ugly, but if you wanted to go further and make things more elegant, then a [NamedServiceAttribute("A")] on the implementation/class could be found by the code in this extension, and it'd work just as well. To be even more fair, Reflection is slow, so an optimization may be in order, but honestly that's something the DI engine should've been helping with. Speed and simplicity are each grand contributors to TCO.
All in all, there's no need for an explicit factory, because "finding a named service" is such a reusable concept, and factory classes don't scale as a solution. And a Func<> seems fine, but a switch block is so bleh, and again, you'll be writing Funcs as often as you'd be writing Factories. Start simple, reusable, with less code, and if that turns out not to do it for ya, then go complex.
First of all, there're two kinds of keystores.
Individual and General
The application will use the one indicated in the startup or the default of the system.
It will be a different folder if JRE or JDK is running, or if you check the personal or the "global" one.
They are encrypted too
In short, the path will be like:
$JAVA_HOME/lib/security/cacerts
for the "general one", who has all the CA for the Authorities and is quite important.
Although this isn't using the np array format, (to lazy to modify my code) this should do what you want... If, you truly want a column vector you will want to transpose the vector result. It all depends on how you are planning to use this.
def getVector(data_array,col):
vector = []
imax = len(data_array)
for i in range(imax):
vector.append(data_array[i][col])
return ( vector )
a = ([1,2,3], [4,5,6])
b = getVector(a,1)
print(b)
Out>[2,5]
So if you need to transpose, you can do something like this:
def transposeArray(data_array):
# need to test if this is a 1D array
# can't do a len(data_array[0]) if it's 1D
two_d = True
if isinstance(data_array[0], list):
dimx = len(data_array[0])
else:
dimx = 1
two_d = False
dimy = len(data_array)
# init output transposed array
data_array_t = [[0 for row in range(dimx)] for col in range(dimy)]
# fill output transposed array
for i in range(dimx):
for j in range(dimy):
if two_d:
data_array_t[j][i] = data_array[i][j]
else:
data_array_t[j][i] = data_array[j]
return data_array_t
try this declare the function outside the ready event.

It's better to use lambda

Before Java 7:
BufferedReader br = new BufferedReader(new FileReader("foo.txt"));
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
Since Java 7, there is no need to close the stream, because it implements autocloseable
try (BufferedReader br = new BufferedReader(new FileReader("foo.txt"))) {
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
i was facing same problem while copying form source directory to destination
source directory had files ~3 lakcs
i used cp with option -r and it's worked for me
cp -r abc/ def/
it will copy all files from abc to def without giving warning of Argument list too long
There's a third way that doesn't require a converter or a change to your view model: use a style:
<Style TargetType="Button">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding IsVisible}" Value="True">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
I tend to prefer this technique because I use it in a lot of cases where what I'm binding to is not boolean - e.g. displaying an element only if its DataContext
is not null, or implementing multi-state displays where different layouts appear based on the setting of an enum in the view model.

If you have Pillow
installed with scipy
and it is still giving you error then check your scipy
version because it has been removed from scipy since 1.3.0rc1
.
rather install scipy 1.1.0
by :
pip install scipy==1.1.0
check https://github.com/scipy/scipy/issues/6212
The method imread
in scipy.misc
requires the forked package of PIL
named Pillow
. If you are having problem installing the right version of PIL try using imread
in other packages:
from matplotlib.pyplot import imread
im = imread(image.png)
To read jpg
images without PIL
use:
import cv2 as cv
im = cv.imread(image.jpg)
You can try
from scipy.misc.pilutil import imread
instead of from scipy.misc import imread

MVC's anti-forgery support writes a unique value to an HTTP-only cookie and then the same value is written to the form. When the page is submitted, an error is raised if the cookie value doesn't match the form value.
It's important to note that the feature prevents cross site request forgeries. That is, a form from another site that posts to your site in an attempt to submit hidden content using an authenticated user's credentials. The attack involves tricking the logged in user into submitting a form, or by simply programmatically triggering a form when the page loads.
The feature doesn't prevent any other type of data forgery or tampering based attacks.
To use it, decorate the action method or controller with the ValidateAntiForgeryToken
attribute and place a call to @Html.AntiForgeryToken()
in the forms posting to the method.
You can embed websites into another website using the <embed>
tag, like so:
<embed src="http://www.example.com" style="width:500px; height: 300px;">
You can change the height, width, and URL to suit your needs.
The <embed>
tag is the most up-to-date way to embed websites, as it was introduced with HTML5.
The only way is to go an underlying level to the JVM.
df.col._jc.toString().encode('utf8')
This is also how it is converted to a str
in the pyspark code itself.
From pyspark/sql/column.py:
def __repr__(self):
return 'Column<%s>' % self._jc.toString().encode('utf8')
It's generally considered bad practice. The problem is that the constants are part of the public "interface" (for want of a better word) of the implementing class. This means that the implementing class is publishing all of these values to external classes even when they are only required internally. The constants proliferate throughout the code. An example is the SwingConstants interface in Swing, which is implemented by dozens of classes that all "re-export" all of its constants (even the ones that they don't use) as their own.
But don't just take my word for it, Josh Bloch also says it's bad:
The constant interface pattern is a poor use of interfaces. That a class uses some constants internally is an implementation detail. Implementing a constant interface causes this implementation detail to leak into the class's exported API. It is of no consequence to the users of a class that the class implements a constant interface. In fact, it may even confuse them. Worse, it represents a commitment: if in a future release the class is modified so that it no longer needs to use the constants, it still must implement the interface to ensure binary compatibility. If a nonfinal class implements a constant interface, all of its subclasses will have their namespaces polluted by the constants in the interface.
An enum may be a better approach. Or you could simply put the constants as public static fields in a class that cannot be instantiated. This allows another class to access them without polluting its own API.
"Select your text, right click, then choose
Style Token
and then using 1st style (2nd style, etc …). At the moment is not possible to save the style tokens but there is an idea pending on Idea torrent you may vote for if your are interested in that."
It should be default, but it might be hidden.
"It might be that something happened to your

so that you only get the basic standard. Have a look in NPPs config folder (%appdata%\Notepad++\
) if thecontextMenu.xml

Anyway you can grab the original standart contextMenu.xml from here and place it into the config folder (or replace the existing xml). Start NPP and you should have quite a long context menu.

I would recommend using rgba(255,255,255,0)
because broken (newest) safari thinks that if you are using transparent
or rgba(0,0,0,0)
in linear-gradent you really mean gray
, For more info please head to - What happens in Safari with the transparent color?
I might do something like the following. Of course, with the wealth of Collection classes, i can't imagine ever needing to use this in any practical code.
public class Shift {
public static <T> T[] left (final T... i) {
if (1 >= i.length) {
return i;
}
final T t = i[0];
int x = 0;
for (; x < i.length - 1; x++) {
i[x] = i[x + 1];
}
i[x] = t;
return i;
}
}
Called with two arguments, it's a swap.
It can be used as follows:
int x = 1;
int y = 2;
Integer[] yx = Shift.left(x,y);
Alternatively:
Integer[] yx = {x,y};
Shift.left(yx);
Then
x = yx[0];
y = yx[1];
Note: it auto-boxes primitives.
The simple way to retrieve checked value of RadioButtonList1 is:
$('#RadioButtonList1 input:checked').val()
Edit by Tim:
where RadioButtonList1
must be the ClientID of the RadioButtonList
var rblSelectedValue = $("#<%= RadioButtonList1.ClientID %> input:checked");
Stop listening to the alternatives, because right now, there aren't any - which aren't just toys.
Apart from the Microsoft development toolchain - it's best technology that money can't buy.

Greatest misnomer in history of the earth. Can your Build pass a Turing test? Fucking ridiculous, a step 10 years back in time with it's ridiculous DSL. Uses IVY dependency management, Maven's middle sibling.
Great for that first project after you graduate from Shockwave development.
You understand XML, and are enthusiastic, but don't really understand build phases, restarting a project 6 months later, why Version Controlling binary artifacts is a false panacea or that someone other than oneself will one day try to work with your project.
If the whole world runs in the same UNIX terminal, and speaks fluent Bash, then yeah. But why not just become a C/C++ programmer, it's much more fun than Java anyhow.
Whatever. Niche, slow. Just develop Ruby then, stay away from Java development.
People use Java where they don't trust Python (anywhere there's money involved). If your system is running Python anyway, you wont even be reading this, unless of course you want the Java money - but are stuck developing Python in some web shop.
In honour of Stallman, I'll learn Lisp - but for Emacs, not so that I run it upon my VM. I feel that it cheapens the experience.
Other answers are correct -- whether a character is invisible or not depends on what font you use. This seems to be a pretty good list to me of characters that are truly invisible (not even space). It contains some chars that the other lists are missing.

Update 2020: As baao notes, Object.fromEntries(arr)
now does this on all modern browsers.
You can use Object.assign, the spread operator, and destructuring assignment for an approach that uses map
instead of @royhowie’s reduce
, which may or may not be more intuitive:
Object.assign(...arr.map(([key, val]) => ({[key]: val})))
E.g.:
var arr = [ [ 'cardType', 'iDEBIT' ],
[ 'txnAmount', '17.64' ],
[ 'txnId', '20181' ],
[ 'txnType', 'Purchase' ],
[ 'txnDate', '2015/08/13 21:50:04' ],
[ 'respCode', '0' ],
[ 'isoCode', '0' ],
[ 'authCode', '' ],
[ 'acquirerInvoice', '0' ],
[ 'message', '' ],
[ 'isComplete', 'true' ],
[ 'isTimeout', 'false' ] ]
var obj = Object.assign(...arr.map(([key, val]) => ({[key]: val})))
console.log(obj)

You can use Programmatic Navigation.In order to go back, you use this:
router.go(n)
Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:

Use the following command
remove(list=c("data_1", "data_2", "data_3"))

In case we have 2 dataframes the following works
DF1<-data.frame('a', 'b')
DF2<-data.frame('c','d')
We change names of DF1 as follows
colnames(DF1)<- colnames(DF2)
This works good for me. I have divided the screen into two halfs: 20% and 80%:
<div style="width: 20%; float:left">
#left content in here
</div>
<div style="width: 80%; float:right">
#right content in there
</div>
For the special case where you search for the n'th occurence of a character (i.e. substring of length 1), the following function works by building a list of all positions of occurences of the given character:
def find_char_nth(string, char, n):
"""Find the n'th occurence of a character within a string."""
return [i for i, c in enumerate(string) if c == char][n-1]
If there are fewer than n
occurences of the given character, it will give IndexError: list index out of range
.
This is derived from @Zv_oDD's answer and simplified for the case of a single character.
.ui-grid, .ui-grid-viewport,.ui-grid-contents-wrapper, .ui-grid-canvas { height: auto !important; }
Alright, think I got it...
Little background first: The reason I needed this was to stick Angular on top of Node Express and have Jade process my partials for me.
So here's whatchya gotta do... (drink beer and spend 20+ hours on it first!!!)...
When you set up your module, save the $routeProvider
globally:
// app.js:
var routeProvider
, app = angular.module('Isomorph', ['ngResource']).config(function($routeProvider){
routeProvider = $routeProvider;
$routeProvider
.when('/', {templateUrl: '/login', controller: 'AppCtrl'})
.when('/home', {templateUrl: '/', controller: 'AppCtrl'})
.when('/login', {templateUrl: '/login', controller: 'AppCtrl'})
.when('/SAMPLE', {templateUrl: '/SAMPLE', controller: 'SAMPLECtrl'})
.when('/map', {templateUrl: '/map', controller: 'MapCtrl'})
.when('/chat', {templateUrl: '/chat', controller: 'ChatCtrl'})
.when('/blog', {templateUrl: '/blog', controller: 'BlogCtrl'})
.when('/files', {templateUrl: '/files', controller: 'FilesCtrl'})
.when('/tasks', {templateUrl: '/tasks', controller: 'TasksCtrl'})
.when('/tasks/new', {templateUrl: '/tasks/new', controller: 'NewTaskCtrl'})
.when('/tasks/:id', {templateUrl: '/tasks', controller: 'ViewTaskCtrl'})
.when('/tasks/:id/edit', {templateUrl: '/tasks', controller: 'EditTaskCtrl'})
.when('/tasks/:id/delete', {templateUrl: '/tasks', controller: 'DeleteTaskCtrl'})
.otherwise({redirectTo: '/login'});
});
// ctrls.js
...
app.controller('EditTaskCtrl', function($scope, $routeParams, $location, $http){
var idParam = $routeParams.id;
routeProvider.when('/tasks/:id/edit/', {templateUrl: '/tasks/' + idParam + '/edit'});
$location.path('/tasks/' + idParam + '/edit/');
});
...
That may be more info than what was needed...
Basically, you'll wanna store your Module's $routeProvider
var globally, eg as routeProvider
so that it can be accessed by your Controllers.
Then you can just use routeProvider
and create a NEW route (you can't 'RESET a route' / 'REpromise'; you must create a new one), I just added a slash (/) at the end so that it is as semantic as the first.
Then (inside your Controller), set the templateUrl
to the view you want to hit.
Take out the controller
property of the .when()
object, lest you get an infinite request loop.
And finally (still inside the Controller), use $location.path()
to redirect to the route that was just created.
If you're interested in how to slap an Angular app onto an Express app, you can fork my repo here: https://github.com/cScarlson/isomorph.
And this method also allows for you to keep the AngularJS Bidirectional Data-Bindings in case you want to bind your HTML to your database using WebSockets: otherwise without this method, your Angular data-bindings will just output {{model.param}}
.
If you clone this at this time, you'll need mongoDB on your machine to run it.
Hope this solves this issue!

Don't drink your bathwater.

For systems where the default Time Zone is not UTC:
TimeZone tz = TimeZone.getTimeZone("UTC");
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm'Z'");
df.setTimeZone(tz);
String nowAsISO = df.format(new Date());
The SimpleDateFormat
instance may be declared as a global constant if needed frequently, but beware that this class is not thread-safe. It must be synchronized if accessed concurrently by multiple threads.

A template class is like a macro, only a whole lot less evil.
Think of a template as a macro. The parameters to the template get substituted into a class (or function) definition, when you define a class (or function) using a template.
The difference is that the parameters have "types" and values passed are checked during compilation, like parameters to functions. The types valid are your regular C++ types, like int and char. When you instantiate a template class, you pass a value of the type you specified, and in a new copy of the template class definition this value gets substituted in wherever the parameter name was in the original definition. Just like a macro.
You can also use the "class
" or "typename
" types for parameters (they're really the same). With a parameter of one of these types, you may pass a type name instead of a value. Just like before, everywhere the parameter name was in the template class definition, as soon as you create a new instance, becomes whatever type you pass. This is the most common use for a template class; Everybody that knows anything about C++ templates knows how to do this.
Consider this template class example code:
#include <cstdio>
template <int I>
class foo
{
void print()
{
printf("%i", I);
}
};
int main()
{
foo<26> f;
f.print();
return 0;
}
It's functionally the same as this macro-using code:
#include <cstdio>
#define MAKE_A_FOO(I) class foo_##I \
{ \
void print() \
{ \
printf("%i", I); \
} \
};
MAKE_A_FOO(26)
int main()
{
foo_26 f;
f.print();
return 0;
}
Of course, the template version is a billion times safer and more flexible.
For some reason none of the above answers seemed to be addressing the case of the real first and only first child of the parent.
#element_id > .class_name:first-child
All the above answers will fail if you want to apply the style to only the first class child within this code.
<aside id="element_id">
Content
<div class="class_name">First content that need to be styled</div>
<div class="class_name">
Second content that don't need to be styled
<div>
<div>
<div class="class_name">deep content - no style</div>
<div class="class_name">deep content - no style</div>
<div>
<div class="class_name">deep content - no style</div>
</div>
</div>
</div>
</div>
</aside>
You can't change or alter the actual :hover
selector through Javascript. You can, however, use mouseenter
to change the style, and revert back on mouseleave
(thanks, @Bryan).
No, there is not, for starters, it is impossible to have an array with elements sharing the same key
$x =array();
$x['foo'] = 'bar' ;
$x['foo'] = 'baz' ; #replaces 'bar'
Secondarily, if you wish to merely prefix the numbers so that
$x[0] --> $x['foo_0']
That is computationally implausible to do without looping. No php functions presently exist for the task of "key-prefixing", and the closest thing is "extract" which will prefix numeric keys prior to making them variables.
The very simplest way is this:
function rekey( $input , $prefix ) {
$out = array();
foreach( $input as $i => $v ) {
if ( is_numeric( $i ) ) {
$out[$prefix . $i] = $v;
continue;
}
$out[$i] = $v;
}
return $out;
}
Additionally, upon reading XMLWriter usage, I believe you would be writing XML in a bad way.
<section>
<foo_0></foo_0>
<foo_1></foo_1>
<bar></bar>
<foo_2></foo_2>
</section>
Is not good XML.
<section>
<foo></foo>
<foo></foo>
<bar></bar>
<foo></foo>
</section>
Is better XML, because when intrepreted, the names being duplicate don't matter because they're all offset numerically like so:
section => {
0 => [ foo , {} ]
1 => [ foo , {} ]
2 => [ bar , {} ]
3 => [ foo , {} ]
}
As others have mentioned, and counter to what the method name would imply, writelines
does not add line separators. This is a textbook case for a generator. Here is a contrived example:
def item_generator(things):
for item in things:
yield item
yield '\n'
def write_things_to_file(things):
with open('path_to_file.txt', 'wb') as f:
f.writelines(item_generator(things))
Benefits: adds newlines explicitly without modifying the input or output values or doing any messy string concatenation. And, critically, does not create any new data structures in memory. IO (writing to a file) is when that kind of thing tends to actually matter. Hope this helps someone!
The accepted answer is good, but has two limitations.
It drops empty lines and lines beginning with ;
To read lines of any content, you need the delayed expansion toggling technic.
@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ text.txt"`) do (
set "var=%%a"
SETLOCAL EnableDelayedExpansion
set "var=!var:*:=!"
echo(!var!
ENDLOCAL
)
Findstr is used to prefix each line with the line number and a colon, so empty lines aren't empty anymore.
DelayedExpansion needs to be disabled, when accessing the %%a
parameter, else exclamation marks !
and carets ^
will be lost, as they have special meanings in that mode.
But to remove the line number from the line, the delayed expansion needs to be enabled.
set "var=!var:*:=!"
removes all up to the first colon (using delims=:
would remove also all colons at the beginning of a line, not only the one from findstr).
The endlocal disables the delayed expansion again for the next line.
The only limitation is now the line length limit of ~8191, but there seems no way to overcome this.
This answer is an update with a little more consideration for OOM and various other leaks.
Assumes you have a directory intended as the destination and a name String already defined.
File destination = new File(directory.getPath() + File.separatorChar + filename);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
source.compress(Bitmap.CompressFormat.PNG, 100, bytes);
FileOutputStream fo = null;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
} catch (IOException e) {
} finally {
try {
fo.close();
} catch (IOException e) {}
}
i achieved this by:
import { ImageBackground } from 'react-native';
<ImageBackground style={ styles.imgBackground }
resizeMode='cover'
source={require('./Your/Path.png')}>
//place your now nested component JSX code here
</ImageBackground>
And then the Styles:
imgBackground: {
width: '100%',
height: '100%',
flex: 1
},
TypeScript users:
I know the OP asked about javascript, but for any TypeScript users who come across this who want to spy on an imported function, here's what you can do.
In the test file, convert the import of the function from this:
import {foo} from '../foo_functions';
x = foo(y);
To this:
import * as FooFunctions from '../foo_functions';
x = FooFunctions.foo(y);
Then you can spy on FooFunctions.foo
:)
spyOn(FooFunctions, 'foo').and.callFake(...);
// ...
expect(FooFunctions.foo).toHaveBeenCalled();
I'd probably change your example to look like this:
<ul ng-repeat="task in tasks">
<li ng-mouseover="enableEdit(task)" ng-mouseleave="disableEdit(task)">{{task.name}}</li>
<span ng-show="task.editable"><a>Edit</a></span>
</ul>
//js
$scope.enableEdit = function(item){
item.editable = true;
};
$scope.disableEdit = function(item){
item.editable = false;
};
I know it's a subtle difference, but makes the domain a little less bound to UI actions. Mentally it makes it easier to think about an item being editable rather than having been moused over.
Example jsFiddle.
After having tried for over two hours, I can safely say that all the method mentioned so far don't work across browsers, or for IE even across browser versions...
For example (top upvoted answer):
filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083); /* IE6,IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083)"; /* IE8 */
rotates twice in IE9, once for filter, and once for -ms-filter, so...
All other mentioned methods do not work either, at least not if you have to set no fixed height/width of the table header cell (with background color), where it should automatically adjust to size of the highest element.

because it works on the development server, then you are sorely mistaken to assume the very same code wouldn't throw a Generic GDI+ exception if you deploy it to a Windows 2003 IIS 6 server...
then use it like this:

}
To your secondary question
var elem1 = $('#elem1'),
elem2 = $('#elem2'),
elem3 = $('#elem3');
You can use the variable as the replacement of selector.
elem1.css({'display':'none'}); //will work
In the below case selector is already stored in a variable.
$(elem1,elem2,elem3).css({'display':'none'}); // will not work
Fixed by running this following comments.
grant all on *.* to 'web2vi'@'%' identified by 'root' with grant option;
FLUSH PRIVILEGES;
if you are getting some_other
instead of web2vi
then you have to change the name accordingly.
If you want to customize your pagination link using next and prev. You can see at Paginator.php Inside it, there's some method I'm using Laravel 7

If you really need a has-next
functionality (because you're just faithfully transcribing an algorithm from a reference implementation in Java, say, or because you're writing a prototype that will need to be easily transcribed to Java when it's finished), it's easy to obtain it with a little wrapper class. For example:
class hn_wrapper(object):
def __init__(self, it):
self.it = iter(it)
self._hasnext = None
def __iter__(self): return self
def next(self):
if self._hasnext:
result = self._thenext
else:
result = next(self.it)
self._hasnext = None
return result
def hasnext(self):
if self._hasnext is None:
try: self._thenext = next(self.it)
except StopIteration: self._hasnext = False
else: self._hasnext = True
return self._hasnext
now something like
x = hn_wrapper('ciao')
while x.hasnext(): print next(x)
emits
c
i
a
o
as required.
Note that the use of next(sel.it)
as a built-in requires Python 2.6 or better; if you're using an older version of Python, use self.it.next()
instead (and similarly for next(x)
in the example usage). [[You might reasonably think this note is redundant, since Python 2.6 has been around for over a year now -- but more often than not when I use Python 2.6 features in a response, some commenter or other feels duty-bound to point out that they are 2.6 features, thus I'm trying to forestall such comments for once;-)]]
$myObj = new stdClass();
// OR
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
I love how easy is to create objects of anonymous type in JavaScript:
//JavaScript
var myObj = {
foo: "Foo value",
bar: "Bar value"
};
console.log(myObj.foo); //Output: Foo value
So I always try to write this kind of objects in PHP like javascript does:
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
//PHP < 5.4
$myObj = (object) array(
"foo" => "Foo value",
"bar" => "Bar value"
);
echo $myObj->foo; //Output: Foo value
But as this is basically an array you can't do things like assign anonymous functions to a property like js does:
//JavaScript
var myObj = {
foo: "Foo value",
bar: function(greeting) {
return greeting + " bar";
}
};
console.log(myObj.bar("Hello")); //Output: Hello bar
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => function($greeting) {
return $greeting . " bar";
}
];
var_dump($myObj->bar("Hello")); //Throw 'undefined function' error
var_dump($myObj->bar); //Output: "object(Closure)"
Well, you can do it, but IMO isn't practical / clean:
$barFunc = $myObj->bar;
echo $barFunc("Hello"); //Output: Hello bar
Also, using this synthax you can find some funny surprises, but works fine for most cases.
This is taken from the docs and it works very well. Here is the link
Where sides are one of:
if you want to give margin to the left use mt-x where x stands for [1,2,3,4,5]
same for padding
example be like
<div class = "mt-5"></div>
<div class = "pt-5"></div>
Use only p-x or m-x for getting padding and margin of x from all sides.

Distributed (a)synchronous computing.
A real world example could be an application-wide notification framework, which sends mails to the stakeholders at various points during the course of application usage. So the application would act as a Producer
by create a Message
object, putting it on a particular Queue
, and moving forward.
There would be a set of Consumer
s who would subscribe to the Queue
in question, and would take care handling the Message
sent across. Note that during the course of this transaction, the Producer
s are decoupled from the logic of how a given Message
would be handled.
Messaging frameworks (ActiveMQ and the likes) act as a backbone to facilitate such Message
transactions by providing MessageBroker
s.

You want to check if an object is NULL/empty. Being NULL and empty are not the same. Like Justin and Brian have already mentioned, in C++ NULL is an assignment you'd typically associate with pointers. You can overload operator= perhaps, but think it through real well if you actually want to do this. Couple of other things:
bool IsEmpty()
method that returns true if an object's variables are reset to some default state? Guess that might bypass the NULL usage.A* p = new A; ... p = NULL;
is bad (no delete p) unless you can ensure your code will be garbage collected. If anything, this'd lead to memory leaks and with several such leaks there's good chance you'd have slow code. class Null {}; Null _NULL;
and then overload operator= and operator!= of other classes depending on your situation. Perhaps you should post us some details about the context to help you better with option 4.

There is no trigger to perform code when the app is deleted from the device. Access to the keychain is dependant on the provisioning profile that is used to sign the application. Therefore no other applications would be able to access this information in the keychain.
It does not help with you aim to remove the password in the keychain when the user deletes application from the device but it should give you some comfort that the password is not accessible (only from a re-install of the original application).
From what I understand of the scikit-image docs (http://scikit-image.org/docs/dev/index.html), imshow() takes a ndarray as an argument, and not a dictionary:
http://scikit-image.org/docs/dev/api/skimage.io.html?highlight=imshow#skimage.io.imshow
Maybe if you post the whole stack trace, we could see that the TypeError comes somewhere deep from imshow().

to_timestamp('2018-11-03 12:35:20.419000', 'YYYY-MM-DD HH24:MI:SS.FF')
Like the docs say, think about it this way. If you were to do an application like a book reader, you will not want to load all the fragments into memory at once. You would like to load and destroy Fragments
as the user reads. In this case you will use FragmentStatePagerAdapter
. If you are just displaying 3 "tabs" that do not contain a lot of heavy data (like Bitmaps
), then FragmentPagerAdapter
might suit you well. Also, keep in mind that ViewPager
by default will load 3 fragments into memory. The first Adapter
you mention might destroy View
hierarchy and re load it when needed, the second Adapter
only saves the state of the Fragment
and completely destroys it, if the user then comes back to that page, the state is retrieved.
Once you are in terminal/command line, access the database/collection you want to use as follows:
show dbs
use <db name>
show collections
choose your collection and type the following to see all contents of that collection:
db.collectionName.find()
More info here on the MongoDB Quick Reference Guide.
If you have a single Buffer
you can use its toString
method that will convert all or part of the binary contents to a string using a specific encoding. It defaults to utf8
if you don't provide a parameter, but I've explicitly set the encoding in this example.
var req = http.request(reqOptions, function(res) {
...
res.on('data', function(chunk) {
var textChunk = chunk.toString('utf8');
// process utf8 text chunk
});
});
If you have streamed buffers like in the question above where the first byte of a multi-byte UTF8
-character may be contained in the first Buffer
(chunk) and the second byte in the second Buffer
then you should use a StringDecoder
. :
var StringDecoder = require('string_decoder').StringDecoder;
var req = http.request(reqOptions, function(res) {
...
var decoder = new StringDecoder('utf8');
res.on('data', function(chunk) {
var textChunk = decoder.write(chunk);
// process utf8 text chunk
});
});
This way bytes of incomplete characters are buffered by the StringDecoder
until all required bytes were written to the decoder.
Underscores look ugly in package names. For what is worth, in case of names compound of three or more words I use initials (for example: com.company.app.ingresoegresofijo (ingreso/egreso fijo) -> com.company.app.iefijo
) and then document the package purpose in package-info.java
.
If you're running in a Linux environment, open the file /etc/hosts.allow
add the following line
ALL
Also check the /etc/hostname
and /etc/host
to see if there might be something wrong there.
I had to change my / etc / host
from
127.0.0.1 localhost
127.0.1.1 AMK
to
127.0.0.1 localhost
127.0.0.1 AMK
also wrote in ALL
in the file /etc/hosts.allow
which was previously completely empty
do not know how safe it is. you have to read more about possible options for /etc/hosts.allow
to do something that requires a touch of security.
The data you want is in the "cols" meta-data table:
SELECT * FROM COLS WHERE COLUMN_NAME = 'id'
This one will give you a list of tables that have all of the columns you want:
select distinct
C1.TABLE_NAME
from
cols c1
inner join
cols c2
on C1.TABLE_NAME = C2.TABLE_NAME
inner join
cols c3
on C2.TABLE_NAME = C3.TABLE_NAME
inner join
cols c4
on C3.TABLE_NAME = C4.TABLE_NAME
inner join
tab t
on T.TNAME = C1.TABLE_NAME
where T.TABTYPE = 'TABLE' --could be 'VIEW' if you wanted
and upper(C1.COLUMN_NAME) like upper('%id%')
and upper(C2.COLUMN_NAME) like upper('%fname%')
and upper(C3.COLUMN_NAME) like upper('%lname%')
and upper(C4.COLUMN_NAME) like upper('%address%')
To do this in a different schema, just specify the schema in front of the table, as in
SELECT * FROM SCHEMA1.COLS WHERE COLUMN_NAME LIKE '%ID%';
If you want to combine the searches of many schemas into one output result, then you could do this:
SELECT DISTINCT
'SCHEMA1' AS SCHEMA_NAME
,TABLE_NAME
FROM SCHEMA1.COLS
WHERE COLUMN_NAME LIKE '%ID%'
UNION
SELECT DISTINCT
'SCHEMA2' AS SCHEMA_NAME
,TABLE_NAME
FROM SCHEMA2.COLS
WHERE COLUMN_NAME LIKE '%ID%'
Update for 2014:
I use geckofx, a healthy open source project that (as of this writing) keeps up to date pretty well with the latest Firefox releases.
To embed Chrome, you might consider another healthy looking open source project, Xilium.cefGlue, based on The Chromium Embedded Framework (CEF).
Both of these support WPF and Winforms, and both projects have support for .net and mono.
require 'json'
hash = JSON.parse string
work with the hash and do what you want to do.
The exec
built-in command mirrors functions in the kernel, there are a family of them based on execve
, which is usually called from C.
exec
replaces the current program in the current process, without fork
ing a new process. It is not something you would use in every script you write, but it comes in handy on occasion. Here are some scenarios I have used it;
We want the user to run a specific application program without access to the shell. We could change the sign-in program in /etc/passwd, but maybe we want environment setting to be used from start-up files. So, in (say) .profile
, the last statement says something like:
exec appln-program
so now there is no shell to go back to. Even if appln-program
crashes, the end-user cannot get to a shell, because it is not there - the exec
replaced it.
We want to use a different shell to the one in /etc/passwd. Stupid as it may seem, some sites do not allow users to alter their sign-in shell. One site I know had everyone start with csh
, and everyone just put into their .login
(csh start-up file) a call to ksh
. While that worked, it left a stray csh
process running, and the logout was two stage which could get confusing. So we changed it to exec ksh
which just replaced the c-shell program with the korn shell, and made everything simpler (there are other issues with this, such as the fact that the ksh
is not a login-shell).
Just to save processes. If we call prog1 -> prog2 -> prog3 -> prog4
etc. and never go back, then make each call an exec. It saves resources (not much, admittedly, unless repeated) and makes shutdown simplier.
You have obviously seen exec
used somewhere, perhaps if you showed the code that's bugging you we could justify its use.
Edit: I realised that my answer above is incomplete. There are two uses of exec
in shells like ksh
and bash
- used for opening file descriptors. Here are some examples:
exec 3< thisfile # open "thisfile" for reading on file descriptor 3
exec 4> thatfile # open "thatfile" for writing on file descriptor 4
exec 8<> tother # open "tother" for reading and writing on fd 8
exec 6>> other # open "other" for appending on file descriptor 6
exec 5<&0 # copy read file descriptor 0 onto file descriptor 5
exec 7>&4 # copy write file descriptor 4 onto 7
exec 3<&- # close the read file descriptor 3
exec 6>&- # close the write file descriptor 6
Note that spacing is very important here. If you place a space between the fd number and the redirection symbol then exec
reverts to the original meaning:
exec 3 < thisfile # oops, overwrite the current program with command "3"
There are several ways you can use these, on ksh use read -u
or print -u
, on bash
, for example:
read <&3
echo stuff >&4
I am proposing my idea about it against any disadvantages array_values( )
function, because I think that is not a direct get function.
In this way it have to create a copy of the values numerically indexed array and then access. If PHP does not hide a method that automatically translates an integer in the position of the desired element, maybe a slightly better solution might consist of a function that runs the array with a counter until it leads to the desired position, then return the element reached.
So the work would be optimized for very large array of sizes, since the algorithm would be best performing indices for small, stopping immediately. In the solution highlighted of array_values( )
, however, it has to do with a cycle flowing through the whole array, even if, for e.g., I have to access $ array [1].
function array_get_by_index($index, $array) {
$i=0;
foreach ($array as $value) {
if($i==$index) {
return $value;
}
$i++;
}
// may be $index exceedes size of $array. In this case NULL is returned.
return NULL;
}
Try writing all the errors to a file.
error_reporting(-1); // reports all errors
ini_set("display_errors", "1"); // shows all errors
ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");
Something like that.
element.funky = function() {
console.log("Click!");
};
element.funky.type = "click";
element.funky.capt = false;
element.addEventListener(element.funky.type, element.funky, element.funky.capt);
// blah blah blah
element.removeEventListener(element.funky.type, element.funky, element.funky.capt);
Since receiving feedback from Andy (quite right, but as with many examples, I wished to show a contextual expansion of the idea), here's a less complicated exposition:
<script id="konami" type="text/javascript" async>
var konami = {
ptrn: "38,38,40,40,37,39,37,39,66,65",
kl: [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
};
document.body.addEventListener( "keyup", function knm ( evt ) {
konami.kl = konami.kl.slice( -9 );
konami.kl.push( evt.keyCode );
if ( konami.ptrn === konami.kl.join() ) {
evt.target.removeEventListener( "keyup", knm, false );
/* Although at this point we wish to remove a listener
we could easily have had multiple "keyup" listeners
each triggering different functions, so we MUST
say which function we no longer wish to trigger
rather than which listener we wish to remove.
Normal scoping will apply to where we can mention this function
and thus, where we can remove the listener set to trigger it. */
document.body.classList.add( "konami" );
}
}, false );
document.body.removeChild( document.getElementById( "konami" ) );
</script>
This allows an effectively anonymous function structure, avoids the use of the practically deprecated callee, and allows easy removal.
Incidentally: The removal of the script element immediately after setting the listener is a cute trick for hiding code one would prefer wasn't starkly obvious to prying eyes (would spoil the surprise ;-)
So the method (more simply) is:
element.addEventListener( action, function name () {
doSomething();
element.removeEventListener( action, name, capture );
}, capture );
orig_float = 232569 / 16000.0
14.5355625
short_float = float("{:.2f}".format(orig_float))

Vim (but not the original Vi!) has tabs which I find (in many contexts) superior to buffers. You can say :tabe [filename]
to open a file in a new tab. Cycling between tabs is done by clicking on the tab or by the key combinations [n]gt
and gT
. Graphical Vim even has graphical tabs.
This was happening in the production environment for me.
rm /vendor/bundle
then
bundle install --deployment
resolved the issue.
When running python (cpython) on windows the <built-in function system>
os.system will execute under the curtains _wsystem while if you're using a non-windows os, it'll use system.
On contrary, Popen should use CreateProcess on windows and _posixsubprocess.fork_exec in posix-based operating-systems.
That said, an important piece of advice comes from os.system docs, which says:
The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes.
If you ever need to do this dynamically, you can use the following:
boolean isInstance(Object object, Class<?> type) {
return type.isInstance(object);
}
You can get an instance of java.lang.Class
by calling the instance method Object::getClass
on any object (returns the Class
which that object is an instance of), or you can do class literals (for example, String.class
, List.class
, int[].class
). There are other ways as well, through the reflection API (which Class
itself is the entry point for).
simple, but yet usefull to get vars/values from URL:
function getUrlVars() {
var vars = [], hash, hashes = null;
if (window.location.href.indexOf("?") && window.location.href.indexOf("&")) {
hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
} else if (window.location.href.indexOf("?")) {
hashes = window.location.href.slice(window.location.href.indexOf('?') + 1);
}
if (hashes != null) {
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars[hash[0]] = hash[1];
}
}
return vars;
}
I found it somewhere on the internet, just fixed few bugs
A bit late answer, but I suggest you have a look at a not well known project on codeplex called ConferenceXP
ConferenceXP is an open source research platform that provides simple, flexible, and extensible conferencing and collaboration using high-bandwidth networks and the advanced multimedia capabilities of Microsoft Windows. ConferenceXP helps researchers and educators develop innovative applications and solutions that feature broadcast-quality audio and video in support of real-time distributed collaboration and distance learning environments.
Full source (it's huge!) is provided. It implements the RTP protocol.
Check if it matches this regex:
'(\.pdf$|\.doc$|\.xls$)'
Note: if you extensions are not at the end of the url, remove the $
characters, but it does weaken it slightly
There are many ways to achieve this, like flatten-and-filter or simply enumerate, but I think using Boolean/mask array is the easiest one (and iirc a much faster one):
>>> y = np.array([[123,24123,32432], [234,24,23]])
array([[ 123, 24123, 32432],
[ 234, 24, 23]])
>>> b = y > 200
>>> b
array([[False, True, True],
[ True, False, False]], dtype=bool)
>>> y[b]
array([24123, 32432, 234])
>>> len(y[b])
3
>>>> y[b].sum()
56789
Update:
As nneonneo has answered, if all you want is the number of elements that passes threshold, you can simply do:
>>>> (y>200).sum()
3
which is a simpler solution.

One very simple way to make a method asynchronous is to use Task.Yield() method. As MSDN states:
You can use await Task.Yield(); in an asynchronous method to force the method to complete asynchronously.
Insert it at beginning of your method and it will then return immediately to the caller and complete the rest of the method on another thread.
private async Task<DateTime> CountToAsync(int num = 1000)
{
await Task.Yield();
for (int i = 0; i < num; i++)
{
Console.WriteLine("#{0}", i);
}
return DateTime.Now;
}
If you know that you're using the same context and not detaching any entities, you can make a generic version like this:
public void InsertOrUpdate<T>(T entity, DbContext db) where T : class
{
if (db.Entry(entity).State == EntityState.Detached)
db.Set<T>().Add(entity);
// If an immediate save is needed, can be slow though
// if iterating through many entities:
db.SaveChanges();
}
db
can of course be a class field, or the method can be made static and an extension, but this is the basics.
Like all the other GUI applications, you have to launch mvim with the wait flag.
git config --global core.editor "mvim --remote-wait"
You may want to use setArray
method as mentioned in the javadoc below:
Sample Code:
PreparedStatement pstmt =
conn.prepareStatement("select * from employee where id in (?)");
Array array = conn.createArrayOf("VARCHAR", new Object[]{"1", "2","3"});
pstmt.setArray(1, array);
ResultSet rs = pstmt.executeQuery();
It looks like the repos for CentOS 5 are disappearing. Most of the ones mentioned in this question are no longer online, don't seem to have Git, or have a really old version of Git. Below is the script I use to build OpenSSL, IDN2, PCRE, cURL and Git from sources. Both the git://
and https://
protocols will be available for cloning.
Over time the names of the archives will need to be updates. For example, as of this writing, openssl-1.0.2k.tar.gz
is the latest available in the 1.0.2 family.
Dale Anderson's answer using RHEL repos looks good at the moment, but its a fairly old version. Red Hat provides Git version 1.8, while the script below builds 2.12 from sources.

In general, it's wrong to use decimal SI prefixes (e.g. kilo, mega) when referring to binary data sizes (except in casual usage). It's ambiguous and causes confusion. To be precise you can use binary prefixes (e.g. 1 mebibyte = 1 MiB = 1024 kibibytes = 2^20 bytes). When someone else uses decimal SI prefixes for binary data you need to get more information before you can know what is meant.

You have to use execute immediate (dynamic sql).
DECLARE
v_owner varchar2(40);
v_table_name varchar2(40);
cursor get_tables is
select distinct table_name,user
from user_tables
where lower(user) = 'schema_name';
begin
open get_tables;
loop
fetch get_tables into v_table_name,v_owner;
EXIT WHEN get_tables%NOTFOUND;
execute immediate 'INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED)
SELECT ''' || v_table_name || ''' , ''' || v_owner ||''',COUNT(*),TO_DATE(SYSDATE,''DD-MON-YY'') FROM ' || v_table_name;
end loop;
CLOSE get_tables;
END;
Based on @Halil great answer, here is simple function how to insert new element after a specific key, while preserving integer keys:
private function arrayInsertAfterKey($array, $afterKey, $key, $value){
$pos = array_search($afterKey, array_keys($array));
return array_merge(
array_slice($array, 0, $pos, $preserve_keys = true),
array($key=>$value),
array_slice($array, $pos, $preserve_keys = true)
);
}
myList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
MyClass selItem = (MyClass) adapter.getItem(position);
}
}
Following what curl does internally for the request (via the method outlined in this answer to "Php - Debugging Curl") answers the question: No, it is not possible to use the curl_setopt
call with CURLOPT_HTTPHEADER
. The second call will overwrite the headers of the first call.
Instead the function needs to be called once with all headers:
$headers = array(
'Content-type: application/xml',
'Authorization: gfhjui',
);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);
Related (but different) questions are:
Add XAttribute
in the constructor of the XElement
, like
new XElement("Conn", new XAttribute("Server", comboBox1.Text));
You can also add multiple attributes or elements via the constructor
new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));
or you can use the Add-Method of the XElement
to add attributes
XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);
I added Bootstrap to a project with section
tags that I had set to 100% of screen height. It worked well until I made the project responsive, at which point I borrowed part of jennyfofenny's answer so my section background matched background of the content when the screen size changed on smaller screens.
My new section
CSS looks like this:
section {
// min-height so it looks good on big screen
// but resizes on a small-screen
min-height: 100%;
min-height: 100vh;
width:100%;
width:100vh;
}
Let's say you've got a section that's a certain color. By using min-height
, if the width of the section shrinks because of a smaller-screen, the height of the section will expand, the content will stay within the section, and your background will stay the desired color.
org.apache.commons.lang3.StringEscapeUtils is now deprecated. You must now use org.apache.commons.text.StringEscapeUtils by

namespace std
{
// define std::byte
enum class byte : unsigned char {};
};
This if your C++ version does not have std::byte will define a byte type in namespace std. Normally you don't want to add things to std, but in this case it is a standard thing that is missing.
std::byte from the STL does much more operations.
First off, EC2 and Elastic Compute Cloud are the same thing.
Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.
EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n
number of instances.
Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.
For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.
In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.
Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/
os._exit()
:
exit(0)
:
exit(1)
:
sys.exit()
:
quit()
:
Basically they all do the same thing, however, it also depends on what you are doing it for.
I don't think you left anything out and I would recommend getting used to quit()
or exit()
.
You would use sys.exit()
and os._exit()
mainly if you are using big files or are using python to control terminal.
Otherwise mainly use exit()
or quit()
.
The semicolon character is used to terminate the SQL statement.
You can either use #
signs around a date value or use Access's (ACE, Jet, whatever) cast to DATETIME
function CDATE()
. As its name suggests, DATETIME
always includes a time element so your literal values should reflect this fact. The ISO date format is understood perfectly by the SQL engine.
Best not to use BETWEEN
for DATETIME
in Access: it's modelled using a floating point type and anyhow time is a continuum ;)
DATE
and TABLE
are reserved words in the SQL Standards, ODBC and Jet 4.0 (and probably beyond) so are best avoided for a data element names:
Your predicates suggest open-open representation of periods (where neither its start date or the end date is included in the period), which is arguably the least popular choice. It makes me wonder if you meant to use closed-open representation (where neither its start date is included but the period ends immediately prior to the end date):
SELECT my_date
FROM MyTable
WHERE my_date >= #2008-09-01 00:00:00#
AND my_date < #2010-09-01 00:00:00#;
Alternatively:
SELECT my_date
FROM MyTable
WHERE my_date >= CDate('2008-09-01 00:00:00')
AND my_date < CDate('2010-09-01 00:00:00');
You can create a temp table variable and insert the data into it, then insert the data into your actual table by selecting it from the temp table.
declare @TableVar table
(
firstCol varchar(50) NOT NULL,
secondCol varchar(50) NOT NULL
)
BULK INSERT @TableVar FROM 'PathToCSVFile' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
GO
INSERT INTO dbo.ExistingTable
(
firstCol,
secondCol
)
SELECT firstCol,
secondCol
FROM @TableVar
GO
I had to solve a similar problem and what I ended up doing was creating a small pdfmerge utility that uses the PDFSharp project which is essentially MIT licensed.
The code is dead simple, I needed a cmdline utility so I have more code dedicated to parsing the arguments than I do for the PDF merging:
using (PdfDocument one = PdfReader.Open("file1.pdf", PdfDocumentOpenMode.Import))
using (PdfDocument two = PdfReader.Open("file2.pdf", PdfDocumentOpenMode.Import))
using (PdfDocument outPdf = new PdfDocument())
{
CopyPages(one, outPdf);
CopyPages(two, outPdf);
outPdf.Save("file1and2.pdf");
}
void CopyPages(PdfDocument from, PdfDocument to)
{
for (int i = 0; i < from.PageCount; i++)
{
to.AddPage(from.Pages[i]);
}
}
Indexing a list is done using double bracket, i.e. hypo_list[[1]]
(e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table
does not return a table but a dataframe (see value section in ?read.table
). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.
Note: In R, the index for the first entry is a 1
(not 0
like in some other languages).
Dataframes
l <- list(anscombe, iris) # put dfs in list
l[[1]] # returns anscombe dataframe
anscombe[1:2, 2] # access first two rows and second column of dataset
[1] 10 8
l[[1]][1:2, 2] # the same but selecting the dataframe from the list first
[1] 10 8
Table objects
tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2) # put tables in a list
tbl1[1:2] # access first two elements of table 1
Now with the list
l[[1]] # access first table from the list
1 2 3 4 5
9 11 12 9 9
l[[1]][1:2] # access first two elements in first table
1 2
9 11
I am using IIS and mysql (directly downloaded, without wamp or xampp) My php was installed in c:\php I was getting the error of "call to undefined function mysql_connect()" For me the change of extension_dir worked. This is what I did. In the php.ini, Originally, I had this line
; On windows: extension_dir = "ext"
I changed it to:
; On windows: extension_dir = "C:\php\ext"
And it worked. Of course, I did the other things also like uncommenting the dll extensions etc, as explained in others remarks.
Your variable size
is declared as: float size;
You can't use a floating point variable as the size of an array - it needs to be an integer value.
You could cast it to convert to an integer:
float *temp = new float[(int)size];
Your other problem is likely because you're writing outside of the bounds of the array:
float *temp = new float[size];
//Getting input from the user
for (int x = 1; x <= size; x++){
cout << "Enter temperature " << x << ": ";
// cin >> temp[x];
// This should be:
cin >> temp[x - 1];
}
Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.
After upgrading lots of packages (Spyder
3 to 4, Keras
and Tensorflow
and lots of their dependencies), I had the same problem today! I cannot figure out what happened; but the (conda-based) virtual environment that kept using Spyder
3 did not have the problem. Although installing tkinter
or changing the backend, via matplotlib.use('TkAgg)
as shown above, or this nice post on how to change the backend, might well resolve the problem, I don't see these as rigid solutions. For me, uninstalling matplotlib
and reinstalling it was magic and the problem was solved.
pip uninstall matplotlib
... then, install
pip install matplotlib
From all the above, this could be a package management problem, and BTW, I use both conda
and pip
, whenever feasible.

I agree with previous comment that might be best to consider a different approach. My suggest would be write a console application and use the windows scheduler:
This will:
You can use:
SELECT COUNT(1) FROM MyTable WHERE ...
or
WHERE [NOT] EXISTS
( SELECT 1 FROM MyTable WHERE ... )
This will be more efficient than SELECT *
since you're simply selecting the value 1 for each row, rather than all the fields.
There's also a subtle difference between COUNT(*) and COUNT(column name):
COUNT(*)
will count all rows, including nullsCOUNT(column name)
will only count non null occurrences of column nameI recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.
IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

I removed your document.getElementById("Save").onclick =
before your functions, because it's an event already being called on your button. I also had to call the two functions separately by the onclick event.
<!DOCTYPE html>
<html>
<head>
<script>
function fun()
{
alert("hello");
//validation code to see State field is mandatory.
}
function f1()
{
alert("f1 called");
//form validation that recalls the page showing with supplied inputs.
}
</script>
</head>
<body>
<form name="form1" id="form1" method="post">
State:
<select id="state ID">
<option></option>
<option value="ap">ap</option>
<option value="bp">bp</option>
</select>
</form>
<table><tr><td id="Save" onclick="f1(); fun();">click</td></tr></table>

There's another layout manager that may be of interest here: Overlay Layout Here's a simple tutorial: OverlayLayout: for layout management of components that lie on top of one another. Overlay Layout allows you to position panels on top of one another, and set a layout inside each panel. You are also able to set size and position of each panel separately.
(The reason I'm answering this question from years ago is because I have stumbled upon the same problem, and I have seen very few mentions of the Overlay Layout on StackOverflow, while it seems to be pretty well documented. Hopefully this may help someone else who keeps searching for it.)
Driver manager logs can be used to get console logs from browser and it will help to identify errors appears in console.
import org.openqa.selenium.logging.LogEntries;
import org.openqa.selenium.logging.LogEntry;
public List<LogEntry> getBrowserConsoleLogs()
{
LogEntries log= driver.manage().logs().get("browser")
List<LogEntry> logs=log.getAll();
return logs;
}
Not tested but you can try something like this :
Declare @count as int
Set @count=1
Declare @inputFile varchar(max)
Declare @Sample Table
(id int,filepath varchar(max) ,Isexists char(3))
while @count<(select max(id) from yourTable)
BEGIN
Set @inputFile =(Select filepath from yourTable where id=@count)
DECLARE @isExists INT
exec master.dbo.xp_fileexist @inputFile ,
@isExists OUTPUT
insert into @Sample
Select @count,@inputFile ,case @isExists
when 1 then 'Yes'
else 'No'
end as isExists
set @count=@count+1
END
So there might be a few things wrong here.
First start by reading how to use XMLHttpRequest.open()
because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send()
. Here's an example from MDN:
var oXHR = new XMLHttpRequest();
oXHR.open("GET", "http://www.mozilla.org/", true);
oXHR.onreadystatechange = function (oEvent) {
if (oXHR.readyState === 4) {
if (oXHR.status === 200) {
console.log(oXHR.responseText)
} else {
console.log("Error", oXHR.statusText);
}
}
};
oXHR.send(null);
Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml
file.
You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:
var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false);
request.send(null);
if (request.status == 0)
console.log(request.responseText);
Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.
Make sure you have the access to the directory you are trying to spool. I tried to spool to root and it did not created the file (e.g c:\test.txt
). You can check where you are spooling by issuing spool
command.
This answer uses the DataFrame.filter method to do this without list comprehension:
import pandas as pd
data = {'spike-2': [1,2,3], 'hey spke': [4,5,6]}
df = pd.DataFrame(data)
print(df.filter(like='spike').columns)
Will output just 'spike-2'. You can also use regex, as some people suggested in comments above:
print(df.filter(regex='spike|spke').columns)
Will output both columns: ['spike-2', 'hey spke']
UPDATE - I do not have Total DNS enabled at GoDaddy because the domain is hosted at DiscountASP. As such, I could not add an A Record and that is why GoDaddy was only offering to forward my subdomain to a different site. I finally realized that I had to go to DiscountASP to add the A Record to point to DreamHost. Now waiting to see if it all works!
Of course, use the stinkin' IP! I'm not sure why that wasn't registering for me. I guess their helper text example of pointing to another url was throwing me off.
Thanks for both of the replies. I 'got it' as soon as I read Bryant's response which was first but Saif kicked it up a notch and added a little more detail.
Thanks!
As much as I love the occasional upvotes I get for this answer (thanks!), this is really not the greatest approach to this problem. Please check out some of the other wonderful answers here, especially the ones that have found solutions without looping.
Still, for the sake of reference, here's my original answer:
<html>
<head>
<style type="text/css">
#dynamicDiv
{
background: #CCCCCC;
width: 300px;
height: 100px;
font-size: 64px;
overflow: hidden;
}
</style>
<script type="text/javascript">
function shrink()
{
var textSpan = document.getElementById("dynamicSpan");
var textDiv = document.getElementById("dynamicDiv");
textSpan.style.fontSize = 64;
while(textSpan.offsetHeight > textDiv.offsetHeight)
{
textSpan.style.fontSize = parseInt(textSpan.style.fontSize) - 1;
}
}
</script>
</head>
<body onload="shrink()">
<div id="dynamicDiv"><span id="dynamicSpan">DYNAMIC FONT</span></div>
</body>
</html>
And here's a version with classes:
<html>
<head>
<style type="text/css">
.dynamicDiv
{
background: #CCCCCC;
width: 300px;
height: 100px;
font-size: 64px;
overflow: hidden;
}
</style>
<script type="text/javascript">
function shrink()
{
var textDivs = document.getElementsByClassName("dynamicDiv");
var textDivsLength = textDivs.length;
// Loop through all of the dynamic divs on the page
for(var i=0; i<textDivsLength; i++) {
var textDiv = textDivs[i];
// Loop through all of the dynamic spans within the div
var textSpan = textDiv.getElementsByClassName("dynamicSpan")[0];
// Use the same looping logic as before
textSpan.style.fontSize = 64;
while(textSpan.offsetHeight > textDiv.offsetHeight)
{
textSpan.style.fontSize = parseInt(textSpan.style.fontSize) - 1;
}
}
}
</script>
</head>
<body onload="shrink()">

This was a new discovery today - after having learned the class/struct reference lesson!
You can use Linq and "Single" if you know the item will be found, because Single returns a variable...
myList.Single(x => x.MyProperty == myValue).OtherProperty = newValue;
This piece of code will return the value of the data attributes eg: data-id, data-time, data-name etc.., I have shown for the id
<a href="#" id="click-demo" data-id="a1">Click</a>
js:
$(this).data("id");
// get the value of the data-id -> a1
$(this).data("id", "a2");
// this will change the data-id -> a2
$(this).data("id");
// get the value of the data-id -> a2
you cannot call a controller method from another controller directly
my solution is to use inheritances and extend your controller from the library controller
class Controller1 extends CI_Controller {
public function index() {
// some codes here
}
public function methodA(){
// code here
}
}
in your controller we call it Mycontoller
it will extends Controller1
include_once (dirname(__FILE__) . "/controller1.php");
class Mycontroller extends Controller1 {
public function __construct() {
parent::__construct();
}
public function methodB(){
// codes....
}
}
and you can call methodA from mycontroller
http://example.com/mycontroller/methodA
http://example.com/mycontroller/methodB
this solution worked for me
This code can be used with timezone
javascript:
let minToHm = (m) => {_x000D_
let h = Math.floor(m / 60);_x000D_
h += (h < 0) ? 1 : 0;_x000D_
let m2 = Math.abs(m % 60);_x000D_
m2 = (m2 < 10) ? '0' + m2 : m2;_x000D_
return (h < 0 ? '' : '+') + h + ':' + m2;_x000D_
}_x000D_
_x000D_
console.log(minToHm(210)) // "+3:30"_x000D_
console.log(minToHm(-210)) // "-3:30"_x000D_
console.log(minToHm(0)) // "+0:00"
_x000D_
minToHm(210)
"+3:30"
minToHm(-210)
"-3:30"
minToHm(0)
"+0:00"
Set editable
to False
and default
to your default value.
http://docs.djangoproject.com/en/stable/ref/models/fields/#editable
b = models.CharField(max_length=7, default='0000000', editable=False)
Also, your id
field is unnecessary. Django will add it automatically.
In my case I had to set the file encoding without BOM.
An alternative way to code Brettski's answer, with which I otherwise agree entirely, might be
With New FileSystemObject
If .FileExists(yourFilePath) Then
.DeleteFile yourFilepath
End If
End With
Same effect but fewer (well, none at all) variable declarations.
The FileSystemObject is a really useful tool and well worth getting friendly with. Apart from anything else, for text file writing it can actually sometimes be faster than the legacy alternative, which may surprise a few people. (In my experience at least, YMMV).
You can Implement this also:- setPage(1, n); where, n = any number.
$products = Mage::getResourceModel('catalog/product_collection')
->addAttributeToSelect('*')
->addAttributeToSelect(array('name', 'price', 'small_image'))
->addFieldToFilter('visibility', Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH) //visible only catalog & searchable product
->addAttributeToFilter('status', 1) // enabled
->setStoreId($storeId)
->setOrder('created_at', 'desc')
->setPage(1, 6);
According to the stack trace, your issue is that your app cannot find org.apache.commons.dbcp.BasicDataSource
, as per this line:
java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource
I see that you have commons-dbcp in your list of jars, but for whatever reason, your app is not finding the BasicDataSource
class in it.

You can create your own custom selector :hasValue
and then use that to find, filter, or test any other jQuery elements.
jQuery.expr[':'].hasValue = function(el,index,match) {
return el.value != "";
};
Then you can find elements like this:
var data = $("form input:hasValue").serialize();
Or test the current element with .is()
var elHasValue = $("#name").is(":hasValue");
jQuery.expr[':'].hasValue = function(el) {_x000D_
return el.value != "";_x000D_
};_x000D_
_x000D_
_x000D_
var data = $("form input:hasValue").serialize();_x000D_
console.log(data)_x000D_
_x000D_
_x000D_
var elHasValue = $("[name='LastName']").is(":hasValue");_x000D_
console.log(elHasValue)

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8001,suspend=y -jar target/cxf-boot-simple-0.0.1-SNAPSHOT.jar

To begin with, it would be best to understand the measure of information
.
measure
the information?When something unlikely happens, we say it's a big news. Also, when we say something predictable, it's not really interesting. So to quantify this interesting-ness
, the function should satisfy
one bit
of information.One natural measure that satisfy the constraints is
I(X) = -log_2(p)
where p is the probability of the event X
. And the unit is in bit
, the same bit computer uses. 0 or 1.
Fair coin flip :
How much information can we get from one coin flip?
Answer : -log(p) = -log(1/2) = 1 (bit)
If a meteor strikes the Earth tomorrow, p=2^{-22}
then we can get 22 bits of information.
If the Sun rises tomorrow, p ~ 1
then it is 0 bit of information.
So if we take expectation on the interesting-ness
of an event Y
, then it is the entropy.
i.e. entropy is an expected value of the interesting-ness of an event.
H(Y) = E[ I(Y)]
More formally, the entropy is the expected number of bits of an event.
Y = 1 : an event X occurs with probability p
Y = 0 : an event X does not occur with probability 1-p
H(Y) = E[I(Y)] = p I(Y==1) + (1-p) I(Y==0)
= - p log p - (1-p) log (1-p)
Log base 2 for all log.
Every answer uses .next()
or uses .beforeFirst()
and then .next()
. But why not this:
result.first();
So You just set the pointer to the first record and go from there. It's available since java 1.2 and I just wanted to mention this for anyone whose ResultSet
exists of one specific record.
Here is an example of how you can use for_each for a map.
std::map<int, int> map;
map.insert(std::pair<int, int>(1, 2));
map.insert(std::pair<int, int>(2, 4));
map.insert(std::pair<int, int>(3, 6));
auto f = [](std::pair<int,int> it) {std::cout << it.first + it.second << std::endl; };
std::for_each(map.begin(), map.end(), f);
You could use sp_executesql
instead of exec
. That allows you to specify an output parameter.
declare @out_var varchar(max);
execute sp_executesql
N'select @out_var = ''hello world''',
N'@out_var varchar(max) OUTPUT',
@out_var = @out_var output;
select @out_var;
This prints "hello world".
del
is often seen in __init__.py
files. Any global variable that is defined in an __init__.py
file is automatically "exported" (it will be included in a from module import *
). One way to avoid this is to define __all__
, but this can get messy and not everyone uses it.
For example, if you had code in __init__.py
like
import sys
if sys.version_info < (3,):
print("Python 2 not supported")
Then your module would export the sys
name. You should instead write
import sys
if sys.version_info < (3,):
print("Python 2 not supported")
del sys
There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.
And then you can copy for example the file "test.txt" from a remote host to the local host
scp [email protected]:test.txt /local/dir
@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.
In UNIX, absolute paths must start with '/'.
you can simply use onBackPressed();

There are at least two ways for achieving this in base graph (my examples are for the x-axis, but work the same for the y-axis):
Use par(xaxp = c(x1, x2, n))
or plot(..., xaxp = c(x1, x2, n))
to define the position (x1
& x2
) of the extreme tick marks and the number of intervals between the tick marks (n
). Accordingly, n+1
is the number of tick marks drawn. (This works only if you use no logarithmic scale, for the behavior with logarithmic scales see ?par
.)
You can suppress the drawing of the axis altogether and add the tick marks later with axis()
.
To suppress the drawing of the axis use plot(... , xaxt = "n")
.
Then call axis()
with side
, at
, and labels
: axis(side = 1, at = v1, labels = v2)
. With side
referring to the side of the axis (1 = x-axis, 2 = y-axis), v1
being a vector containing the position of the ticks (e.g., c(1, 3, 5)
if your axis ranges from 0 to 6 and you want three marks), and v2
a vector containing the labels for the specified tick marks (must be of same length as v1
, e.g., c("group a", "group b", "group c")
). See ?axis
and my updated answer to a post on stats.stackexchange for an example of this method.
Use -d
(full list of file tests)
if (-d "cgi-bin") {
# directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
# cgi-bin exists but is not a directory
}
else {
# nothing called cgi-bin exists
}
As a note, -e
doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f
.
It's because there can only be one definition of A::a
that all the translation units use.
If you performed static int a = 3;
in a class in a header included in all a translation units then you'd get multiple definitions. Therefore, non out-of-line definition of a static is forcibly made a compiler error.
Using static inline
or static const
remedies this. static inline
only concretises the symbol if it is used in the translation unit and ensures the linker only selects and leaves one copy if it's defined in multiple translation units due to it being in a comdat group. const
at file scope makes the compiler never emit a symbol because it's always substituted immediately in the code unless extern
is used, which is not permitted in a class.
One thing to note is static inline int b;
is treated as a definition whereas static const int b
or static const A b;
are still treated as a declaration and must be defined out-of-line if you don't define it inside the class. Interestingly static constexpr A b;
is treated as a definition, whereas static constexpr int b;
is an error and must have an initialiser (this is because they now become definitions and like any const/constexpr definition at file scope, they require an initialiser which an int doesn't have but a class type does because it has an implicit = A()
when it is a definition -- clang allows this but gcc requires you to explicitly initialise or it is an error. This is not a problem with inline instead). static const A b = A();
is not allowed and must be constexpr
or inline
in order to permit an initialiser for a static object with class type i.e to make a static member of class type more than a declaration. So yes in certain situations A a;
is not the same as explicitly initialising A a = A();
(the former can be a declaration but if only a declaration is allowed for that type then the latter is an error. The latter can only be used on a definition. constexpr
makes it a definition). If you use constexpr
and specify a default constructor then the constructor will need to be constexpr
#include<iostream>
struct A
{
int b =2;
mutable int c = 3; //if this member is included in the class then const A will have a full .data symbol emitted for it on -O0 and so will B because it contains A.
static const int a = 3;
};
struct B {
A b;
static constexpr A c; //needs to be constexpr or inline and doesn't emit a symbol for A a mutable member on any optimisation level
};
const A a;
const B b;
int main()
{
std::cout << a.b << b.b.b;
return 0;
}
A static member is an outright file scope declaration extern int A::a;
(which can only be made in the class and out of line definitions must refer to a static member in a class and must be definitions and cannot contain extern) whereas a non-static member is part of the complete type definition of a class and have the same rules as file scope declarations without extern
. They are implicitly definitions. So int i[]; int i[5];
is a redefinition whereas static int i[]; int A::i[5];
isn't but unlike 2 externs, the compiler will still detect a duplicate member if you do static int i[]; static int i[5];
in the class.
I tried everything on this thread but nothing worked. My problem: my computer was charging the device when I was connecting the cable on, so I assumed the cable was working, but not. After I swap the cable, adb devices
worked. The cable was the issue.
Beautiful Soup 4 supports most CSS selectors with the .select()
method, therefore you can use an id
selector such as:
soup.select('#articlebody')
If you need to specify the element's type, you can add a type selector before the id
selector:
soup.select('div#articlebody')
The .select()
method will return a collection of elements, which means that it would return the same results as the following .find_all()
method example:
soup.find_all('div', id="articlebody")
# or
soup.find_all(id="articlebody")
If you only want to select a single element, then you could just use the .find()
method:
soup.find('div', id="articlebody")
# or
soup.find(id="articlebody")
You need to follow these steps before the token authentication
Create a Cluster Admin service account
kubectl create serviceaccount dashboard -n default
Add the cluster binding rules to your dashboard account
kubectl create clusterrolebinding dashboard-admin -n default --clusterrole=cluster-admin --serviceaccount=default:dashboard
Get the secret token with this command
kubectl get secret $(kubectl get serviceaccount dashboard -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode
Choose token authentication in the Kubernetes dashboard login page
Now you can able to login
You can do it with an UPDATE statement setting the value with a REPLACE

You will want to be extremely careful when doing this! I highly recommend doing a backup first.
You have to encode your email as multipart mime and then you can attach emails as attachments basically. You reference them by cid in the email.
Alternatively you could not attach them to the email and use URLs directly but most mail programs will block this as spammers use the trick to detect the liveness of email addresses.
You don't say what language but here is one example.
To alter the password expiry policy for a certain user profile in Oracle first check which profile the user is using:
select profile from DBA_USERS where username = '<username>';
Then you can change the limit to never expire using:
alter profile <profile_name> limit password_life_time UNLIMITED;
If you want to previously check the limit you may use:
select resource_name,limit from dba_profiles where profile='<profile_name>';
Window.Show will show the window, and continue execution -- it's a non-blocking call.
Window.ShowDialog will block the calling thread (kinda [1]), and show the dialog. It will also block interaction with the parent/owning window. When the dialog is dismissed (for whatever reason), ShowDialog will return to the caller, and will allow you to access DialogResult (if you want it).
[1] It will keep the dispatcher pumping by pushing a dispatcher frame onto the WPF dispatcher. This will cause the message pump to keep pumping.
If you want vertical spacing between elements, use a margin.
Don't add extra elements if you don't need to.
Example: SELECT DISTINCT names FROM student ;
CREATE TABLE Persons ( Id varchar NOT NULL UNIQUE, Name varchar(20) );
You could also write your own parser to pull the URL of all the images and then dynamically create new imageviews and pass in the urls.
When you run a program as a background process (by adding an &
after it), e.g.:
python -m SimpleHTTPServer 8888 &
If the terminal window is still open you can do:
jobs
To get a list of all background jobs within the running shell's process.
It could look like this:
$ jobs
[1]+ Running python -m SimpleHTTPServer 8888 &
To kill a job, you can either do kill %1
to kill job "[1]", or do fg %1
to put the job in the foreground (fg) and then use ctrl-c to kill it. (Simply entering fg
will put the last backgrounded process in the foreground).
With respect to SimpleHTTPServer it seems kill %1
is better than fg
+ ctrl-c. At least it doesn't protest with the kill command.
The above has been tested in Mac OS, but as far as I can remember it works just the same in Linux.
Update: For this to work, the web server must be started directly from the command line (verbatim the first code snippet). Using a script to start it will put the process out of reach of jobs
.
The bug is probably somewhere else in your code, because it should work fine:
>>> 3 not in [2, 3, 4]
False
>>> 3 not in [4, 5, 6]
True
Or with tuples:
>>> (2, 3) not in [(2, 3), (5, 6), (9, 1)]
False
>>> (2, 3) not in [(2, 7), (7, 3), "hi"]
True
Also notice the order of parameters on the command line. At least on some systems (e.g. CentOS 6):
wget -O FILE URL
works. But:
wget URL -O FILE
does not work.
There are two ways. One is to aggregate:
SELECT array_agg(column_name::TEXT)
FROM information.schema.columns
WHERE table_name = 'aean'
The other is to use an array constructor:
SELECT ARRAY(
SELECT column_name
FROM information.schema.columns
WHERE table_name = 'aean')
I'm presuming this is for plpgsql. In that case you can assign it like this:
colnames := ARRAY(
SELECT column_name
FROM information.schema.columns
WHERE table_name='aean'
);
RGB values fall nicely on bit boundaries; decimal digits don't. I don't think there's an easy way to do this using bitwise operators at all. You'd need to use decimal operators like modulo 10 (% 10).
What about using idate()? idate()
$integer = idate('w', $timestamp);
I am facing the same problem but only in Chrome Canary and searching a solution I've found this post.
one of the next versions of Chrome is going to force all domains ending on .dev (and .foo) to be redirected to HTTPs via a preloaded HTTP Strict Transport Security (HSTS) header.
{ "name": "dev", "include_subdomains": true, "mode": "force-https" },
{ "name": "foo", "include_subdomains": true, "mode": "force-https" },
So, change your domains.
With abstract classes you can have some kind of skeleton for other classes to extend.
You can't instantiate them but you can put some common implementation which you can use in the classes that extend them.
This happened to me.
Apparently it is because Java does not have permission to create registry keys.
After jQuery 1.6, using promise seems like a better option.
var $div1 = $('#div1');
var fadeOutDone = $div1.fadeOut().promise();
// do your logic here, e.g.fetch your 2nd image url
$.get('secondimageinfo.json').done(function(data){
fadeoOutDone.then(function(){
$div1.html('<img src="' + data.secondImgUrl + '" alt="'data.secondImgAlt'">');
$div1.fadeIn();
});
});
Go in xampp/apache/conf/httpd.conf and open it. Then just chang 2 lines
Listen 80
to
Listen 81
And
ServerName localhost:80
to
ServerName localhost:81
Then start using admin privileges.
As I am working in a corporate environment where developers faces firewall issues, none of the other answers resolved my issue.
As the port is not used by Skype, but by some other internal applications, I followed the below steps to resolve the issue:
Step 1 - From the XAMPP Control Panel, under Apache, click the Config button, and select the Apache (httpd.conf).
Inside the httpd.conf file, somehow I found a line that says:
Listen 80 And change the 80 into any number / port you want. In my scenario I’m using port 8080.
Listen 8080 Still from the httpd.conf file,
You should also do this in the same process Still from the httpd-ssl.conf file, find another line that says
ServerName localhost:443 And change 443 to 4433.
ServerName localhost:4433 Remember to save the httpd.conf and httpd-ssl.conf files after performing some changes. Then restart the Apache service.

In my case, Android Studio created project including support library which version is RC
or beta
.
So I tried downgrade version of support library, then worked.
If your library version is RC or beta, try downgrade.
Downgrade this
implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
to this
implementation 'com.android.support:appcompat-v7:27.1.1'
and downgrade also compileSdkVersion, targetSdkVersion if you need.
To build on Oli's solution (https://stackoverflow.com/a/5056797/2472351) using multimaps, you can replace the two template functions he used with the following:
template <typename A, typename B>
multimap<B, A> flip_map(map<A,B> & src) {
multimap<B,A> dst;
for(map<A, B>::const_iterator it = src.begin(); it != src.end(); ++it)
dst.insert(pair<B, A>(it -> second, it -> first));
return dst;
}
Here is an example program that shows all the key-value pairs being preserved after performing the flip.
#include <iostream>
#include <map>
#include <string>
#include <algorithm>
using namespace std;
template <typename A, typename B>
multimap<B, A> flip_map(map<A,B> & src) {
multimap<B,A> dst;
for(typename map<A, B>::const_iterator it = src.begin(); it != src.end(); ++it)
dst.insert(pair<B, A>(it -> second, it -> first));
return dst;
}
int main() {
map<string, int> test;
test["word"] = 1;
test["spark"] = 15;
test["the"] = 2;
test["mail"] = 3;
test["info"] = 3;
test["sandwich"] = 15;
cout << "Contents of original map:\n" << endl;
for(map<string, int>::const_iterator it = test.begin(); it != test.end(); ++it)
cout << it -> first << " " << it -> second << endl;
multimap<int, string> reverseTest = flip_map(test);
cout << "\nContents of flipped map in descending order:\n" << endl;
for(multimap<int, string>::const_reverse_iterator it = reverseTest.rbegin(); it != reverseTest.rend(); ++it)
cout << it -> first << " " << it -> second << endl;
cout << endl;
}
Result:
var startDate = moment(startDateVal, "DD.MM.YYYY");//Date format
var endDate = moment(endDateVal, "DD.MM.YYYY");
var isAfter = moment(startDate).isAfter(endDate);
if (isAfter) {
window.showErrorMessage("Error Message");
$(elements.endDate).focus();
return false;
}
