HTML5 allows to use **TTF** fonts in your CSS:

    @font-face {
      font-family: &#39;Tagesschrift&#39;;
      src: url(&#39;tagesschrift.ttf&#39;);
    }

To use it:

    h1, h2, h3 { font-family: &#39;Tagesschrift&#39;, &#39;Georgia&#39;, serif; }

You use [Font Embedding][1].

It will affect the overall load time of the page as the font data has to be downloaded as well as the other content, styles etc. However, it will be cached so only impacts on the first view of the page.

I want to update the accepted answer due to a significant passage of time. The following is what [Font Squirrel](https://www.fontsquirrel.com/tools/webfont-generator) outputs under their recommended &#39;Optimal&#39; setting. Supporting `.ttf` at this point is no longer important and should be ignored.

    font-family: &#39;Tagesschrift&#39;;
      src: url(&#39;tagesschrift.woff2&#39;) format(&#39;woff2&#39;),
           url(&#39;tagesschrift.woff&#39;) format(&#39;woff&#39;);

Font embedding can be a bit complicated due to browser compatibility issues. For example, Safari only supports SVG fonts. IE only supports .eot, which must first be converted from .ttf

I have found the easiest way to use custom fonts is with [Google Fonts][1]
Besides having the free google font directory to choose from, there are a few providers that provide a much wider selection of fonts for free and to purchase.

Using HTML5 Websockets, can I open a socket directly between 2 clients (browsers) (assuming I know their IP addresses and there are no NAT traversal issues). I want to send some data directly from one browser to another browser, essentially creating a P2P network. Everything I&#39;ve read so far on the web, websockets are all used to communicate between client and server, but nothing about client to client.

I have several [PHP][1] pages echoing out various things into [HTML][2] pages with the following code.

    &lt;meta http-equiv=&quot;Content-type&quot; content=&quot;text/html; charset=utf-8&quot; /&gt;

However, when I validate using the [W3C validator][3] it comes up with:

&gt; The character encoding specified in the HTTP header (iso-8859-1) is different from the value in the &lt;meta&gt; element (utf-8).

I am quite new to PHP, and I was wondering if I could and should change the header for the PHP files to match the HTML files.

I&#39;m working with PHP, and I&#39;m making an action page which a form posts to. The page checks for errors, then if everything is fine, it redirects them to the page where the data has been posted. If not, I need to to redirect them back to the page they were at with an error and the POST variables. Here is the gist of how it works.

The HTML would look like this...

    &lt;form name=&quot;example&quot; action=&quot;action.php&quot; method=&quot;POST&quot;&gt;
      &lt;input type=&quot;text&quot; name=&quot;one&quot;&gt;
      &lt;input type=&quot;text&quot; name=&quot;two&quot;&gt;
      &lt;input type=&quot;text&quot; name=&quot;three&quot;&gt;
      &lt;input type=&quot;submit&quot; value=&quot;Submit!&quot;&gt;
    &lt;/form&gt;

action.php would look like this...

    if(error_check($_POST[&#39;one&#39;]) == true){
        header(&#39;Location: form.php&#39;);
        // Here is where I need the data to POST back to the form page.
    } else {
        // function to insert data into database
        header(&#39;Location: posted.php&#39;);
    }

In the case of an error, I need it to POST back to the first page.
I can&#39;t use GET, because the input will be too large.
I don&#39;t want to use SESSION, if possible.
Is this possible?

In Java we see lots of places where the `final` keyword can be used but its use is uncommon. 

For example:

    String str = &quot;abc&quot;;
    System.out.println(str);

In the above case, `str` can be `final` but this is commonly left off. 

When a method is never going to be overridden we can use final keyword. Similarly in case of a class which is not going to be inherited.

Does the use of final keyword in any or all of these cases really improve performance? If so, then how? Please explain. If the proper use of `final` really matters for performance, what habits should a Java programmer develop to make best use of the keyword?

I know that the topic of &quot;C++ delegates&quot; has been done to death, and both http://www.codeproject.com and http://stackoverflow.com deeply cover the question. 

Generally, it seems that [Don Clugston&#39;s fastest possible delegate][1] is the first choice for many people. There are a few other popular ones.

However, I noticed that most of those articles are old (around 2005) and many design choices seem to have been made taking in account old compilers like VC7.


I&#39;m in need of a very fast delegate implementation for an audio application. 

I still need it to be portable (Windows, Mac, Linux) but I only use modern compilers (VC9, the one in VS2008 SP1 and GCC 4.5.x). 

My main criteria are:

 - it must be fast! 
 - it must be forward-compatible with newer versions of the compilers. I have some doubts about that with Don&#39;s implementation because he explicitly states it&#39;s not standard-compliant.
 - optionally, a KISS-syntax and ease-of-use is nice to have
 - multicast would be nice, although I&#39;m convinced it&#39;s really easy to build it around any delegate library

Furthermore, I don&#39;t really need exotic features. I just need the good old pointer-to-method thing. No need to support static methods, free functions or things like that.

As of today, what is the recommended approach? Still use [Don&#39;s version][2]? 
Or is there a &quot;community consensus&quot; about another option? 

I really don&#39;t want to use Boost.signal/signal2 because it&#39;s not acceptable in terms of performance. A dependency on QT is not acceptable as well.

Furthermore, I&#39;ve seen some newer libraries while googling, like for example [cpp-events][3] but I couldn&#39;t find any feedback  from users, including on SO.

5 years later, is there something better than the &quot;Fastest Possible C++ Delegates&quot;?

For example (not sure if most representative example though):

    N &lt;- 1e6
    d1 &lt;- data.frame(x=sample(N,N), y1=rnorm(N))
    d2 &lt;- data.frame(x=sample(N,N), y2=rnorm(N))

This is what I&#39;ve got so far:

    d &lt;- merge(d1,d2)
    # 7.6 sec
    
    library(plyr)
    d &lt;- join(d1,d2)
    # 2.9 sec
    
    library(data.table)
    dt1 &lt;- data.table(d1, key=&quot;x&quot;)
    dt2 &lt;- data.table(d2, key=&quot;x&quot;)
    d &lt;- data.frame( dt1[dt2,list(x,y1,y2=dt2$y2)] )
    # 4.9 sec
    
    library(sqldf)
    sqldf()
    sqldf(&quot;create index ix1 on d1(x)&quot;)
    sqldf(&quot;create index ix2 on d2(x)&quot;)
    d &lt;- sqldf(&quot;select * from d1 inner join d2 on d1.x=d2.x&quot;)
    sqldf()
    # 17.4 sec

What&#39;s the fastest way to merge/join data.frames in R?

Every time I mention slow performance of C++ standard library iostreams, I get met with a wave of disbelief.  Yet I have profiler results showing large amounts of time spent in iostream library code (full compiler optimizations), and switching from iostreams to OS-specific I/O APIs and custom buffer management does give an order of magnitude improvement.

What extra work is the C++ standard library doing, is it required by the standard, and is it useful in practice?  Or do some compilers provide implementations of iostreams that are competitive with manual buffer management?

Benchmarks
-
To get matters moving, I&#39;ve written a couple of short programs to exercise the iostreams internal buffering:

* putting binary data into an `ostringstream` http://ideone.com/2PPYw
* putting binary data into a `char[]` buffer http://ideone.com/Ni5ct
* putting binary data into a `vector&lt;char&gt;` using `back_inserter` http://ideone.com/Mj2Fi
* **NEW**: `vector&lt;char&gt;` simple iterator http://ideone.com/9iitv
* **NEW**: putting binary data directly into `stringbuf` http://ideone.com/qc9QA
* **NEW**: `vector&lt;char&gt;` simple iterator plus bounds check http://ideone.com/YyrKy

Note that the `ostringstream` and `stringbuf` versions run fewer iterations because they are so much slower.

On ideone, the `ostringstream` is about 3 times slower than `std:copy` + `back_inserter` + `std::vector`, and about 15 times slower than `memcpy` into a raw buffer.  This feels consistent with before-and-after profiling when I switched my real application to custom buffering.

These are all in-memory buffers, so the slowness of iostreams can&#39;t be blamed on slow disk I/O, too much flushing, synchronization with stdio, or any of the other things people use to excuse observed slowness of the C++ standard library iostream.

It would be nice to see benchmarks on other systems and commentary on things common implementations do (such as gcc&#39;s libc++, Visual C++, Intel C++) and how much of the overhead is mandated by the standard.

Rationale for this test
-
A number of people have correctly pointed out that iostreams are more commonly used for formatted output.  However, they are also the only modern API provided by the C++ standard for binary file access.  But the real reason for doing performance tests on the internal buffering applies to the typical formatted I/O: if iostreams can&#39;t keep the disk controller supplied with raw data, how can they possibly keep up when they are responsible for formatting as well?

Benchmark Timing
-

All these are per iteration of the outer (`k`) loop.

On ideone (gcc-4.3.4, unknown OS and hardware):

 * `ostringstream`: 53 milliseconds
 * `stringbuf`: 27 ms
 * `vector&lt;char&gt;` and `back_inserter`: 17.6 ms
 * `vector&lt;char&gt;` with ordinary iterator: 10.6 ms
 * `vector&lt;char&gt;` iterator and bounds check: 11.4 ms
 * `char[]`: 3.7 ms

On my laptop (Visual C++ 2010 x86, `cl /Ox /EHsc`, Windows 7 Ultimate 64-bit, Intel Core i7, 8 GB RAM):

 * `ostringstream`: 73.4 milliseconds, 71.6 ms
 * `stringbuf`: 21.7 ms, 21.3 ms
 * `vector&lt;char&gt;` and `back_inserter`: 34.6 ms, 34.4 ms
 * `vector&lt;char&gt;` with ordinary iterator: 1.10 ms, 1.04 ms
 * `vector&lt;char&gt;` iterator and bounds check: 1.11 ms, 0.87 ms, 1.12 ms, 0.89 ms, 1.02 ms, 1.14 ms
 * `char[]`: 1.48 ms, 1.57 ms

Visual C++ 2010 x86, with Profile-Guided Optimization `cl /Ox /EHsc /GL /c`, `link /ltcg:pgi`, run, `link /ltcg:pgo`, measure:

 * `ostringstream`: 61.2 ms, 60.5 ms
 * `vector&lt;char&gt;` with ordinary iterator: 1.04 ms, 1.03 ms


Same laptop, same OS, using cygwin gcc 4.3.4 `g++ -O3`:

 * `ostringstream`: 62.7 ms, 60.5 ms
 * `stringbuf`: 44.4 ms, 44.5 ms
 * `vector&lt;char&gt;` and `back_inserter`: 13.5 ms, 13.6 ms
 * `vector&lt;char&gt;` with ordinary iterator: 4.1 ms, 3.9 ms
 * `vector&lt;char&gt;` iterator and bounds check: 4.0 ms, 4.0 ms
 * `char[]`: 3.57 ms, 3.75 ms

Same laptop, Visual C++ 2008 SP1, `cl /Ox /EHsc`:

 * `ostringstream`: 88.7 ms, 87.6 ms
 * `stringbuf`: 23.3 ms, 23.4 ms
 * `vector&lt;char&gt;` and `back_inserter`: 26.1 ms, 24.5 ms
 * `vector&lt;char&gt;` with ordinary iterator: 3.13 ms, 2.48 ms
 * `vector&lt;char&gt;` iterator and bounds check: 2.97 ms, 2.53 ms
 * `char[]`: 1.52 ms, 1.25 ms

Same laptop, Visual C++ 2010 64-bit compiler:

 * `ostringstream`: 48.6 ms, 45.0 ms
 * `stringbuf`: 16.2 ms, 16.0 ms
 * `vector&lt;char&gt;` and `back_inserter`: 26.3 ms, 26.5 ms
 * `vector&lt;char&gt;` with ordinary iterator: 0.87 ms, 0.89 ms
 * `vector&lt;char&gt;` iterator and bounds check: 0.99 ms, 0.99 ms
 * `char[]`: 1.25 ms, 1.24 ms


EDIT: Ran all twice to see how consistent the results were.  Pretty consistent IMO.

NOTE: On my laptop, since I can spare more CPU time than ideone allows, I set the number of iterations to 1000 for all methods.  This means that `ostringstream` and `vector` reallocation, which takes place only on the first pass, should have little impact on the final results.

EDIT: Oops, found a bug in the `vector`-with-ordinary-iterator, the iterator wasn&#39;t being advanced and therefore there were too many cache hits.  I was wondering how `vector&lt;char&gt;` was outperforming `char[]`.  It didn&#39;t make much difference though, `vector&lt;char&gt;` is still faster than `char[]` under VC++ 2010.

Conclusions
-
Buffering of output streams requires three steps each time data is appended:

* Check that the incoming block fits the available buffer space.
* Copy the incoming block.
* Update the end-of-data pointer.

The latest code snippet I posted, &quot;`vector&lt;char&gt;` simple iterator plus bounds check&quot; not only does this, it also allocates additional space and moves the existing data when the incoming block doesn&#39;t fit.  As Clifford pointed out, buffering in a file I/O class wouldn&#39;t have to do that, it would just flush the current buffer and reuse it.  So this should be an upper bound on the cost of buffering output.  And it&#39;s exactly what is needed to make a working in-memory buffer.

So why is `stringbuf` 2.5x slower on ideone, and at least 10 times slower when I test it?  It isn&#39;t being used polymorphically in this simple micro-benchmark, so that doesn&#39;t explain it.

Does the C++ standard mandate poor performance for iostreams, or am I just dealing with a poor implementation?

**Can anyone beat the performance of my integer to std::string code, linked below?**


There are already several questions that explain how to convert an integer into a `std::string` in C++, such as [this one](https://stackoverflow.com/questions/228005/alternative-to-itoa-for-converting-integer-to-string-c), but none of the solutions provided are efficient.

Here is compile-ready code for some common methods to compete against:

* The &quot;C++ way&quot;, using stringstream: http://ideone.com/jh3Sa
* sprintf, which SO-ers usually recommend to the performance conscious: http://ideone.com/82kwR

Contrary to [popular belief](https://stackoverflow.com/questions/228005/alternative-to-itoa-for-converting-integer-to-string-c/228041#228041), `boost::lexical_cast` has its own implementation ([white paper](http://www.accu.org/var/uploads/journals/overload74.pdf)) and does not use `stringstream` and numeric insertion operators.  I&#39;d really like to see its performance compared, because [this other question suggests that it&#39;s miserable](https://stackoverflow.com/questions/1250795/very-poor-boostlexical-cast-performance).

And my own contribution, which is competitive on desktop computers, and demonstrates an approach that runs at full speed on embedded systems as well, unlike algorithms dependent on integer modulo:

* Ben&#39;s algorithms: http://ideone.com/SsEUW

If you want to use that code, I&#39;ll make it available under a simplified BSD license (commercial use allowed, attribution required).  Just ask.

Finally, the function `ltoa` is non-standard but widely available.

* ltoa version, for anyone who has a compiler that provides it (ideone doesn&#39;t): http://ideone.com/T5Wim

I&#39;ll post my performance measurements as an answer shortly.


Rules for algorithms
-

* Provide code for a conversion of at least 32-bit signed and unsigned integers into decimal.
* Produce output as a `std::string`.
* No tricks that are incompatible with threading and signals (for example, static buffers).
* You may assume an ASCII character set.
* Make sure to test your code on `INT_MIN` on a two&#39;s complement machine where the absolute value is not representable.
* Ideally, the output should be character-for-character identical with the canonical C++ version using `stringstream`, http://ideone.com/jh3Sa, but anything that is clearly understandable as the correct number is ok, too.
* **NEW**: Although you can use whatever compiler and optimizer options (except completely disabled) you want for the comparison, the code needs to also compile and give correct results under at least VC++ 2010 and g++.

Hoped-for Discussion
-

Besides better algorithms, I&#39;d also like to get some benchmarks on several different platforms and compilers (let&#39;s use MB/s throughput as our standard unit of measure).  I believe that the code for my algorithm (I know the `sprintf` benchmark takes some shortcuts -- now fixed) is well-defined behavior by the standard, at least under the ASCII assumption, but if you see any undefined behavior or inputs for which the output is invalid, please point that out.

Conclusions:
-

Different algorithms perform for g++ and VC2010, likely due to the different implementations of `std::string` on each.  VC2010 clearly does a better job with NRVO, getting rid of return-by-value helped only on gcc.

Code was found that outperforms `sprintf` by an order of magnitude.  `ostringstream` falls behind by a factor of 50 and more.

The winner of the challenge is user434507 who produces code that runs 350% of the speed of my own on gcc.  Further entries are closed due to the whims of the SO community.

The current (final?) speed champions are:

* For gcc: user434507, at 8 times faster than `sprintf`: http://ideone.com/0uhhX
* For Visual C++: Timo, at 15 times faster than `sprintf`: http://ideone.com/VpKO3

I am designing a small C# application and there is a web browser in it. I currently have all of my defaults on my computer say google chrome is my default browser, yet when I click a link in my application to open in a new window, it opens internet explorer. Is there any way to make these links open in the default browser instead? Or is there something wrong on my computer?

My problem is that I have a webbrowser in the application, so say you go to google and type in &quot;stack overflow&quot; and right click the first link and click &quot;Open in new window&quot; it opens in IE instead of Chrome. Is this something I have coded improperly, or is there a setting not correct on my computer

===EDIT===

This is really annoying. I am already aware that the browser is IE, but I had it working fine before. When I clicked a link it opened in chrome. I was using sharp develop to make the application at that time because I could not get c# express to start up. I did a fresh windows install and since I wasn&#39;t too far along in my application, I decided to start over, and now I am having this problem. That is why I am not sure if it is my computer or not. Why would IE start up the whole browser when a link is clicked rather than simply opening the new link in the default browser?

I recently upgraded to IE9-beta. Now, In my .Net (3.5) WinForm application I want to use `WebBrowser` control. 

So my question is, whether the `WebBrowser` control will exhibit all properties and functions of IE9? 

My concern is, I want to render some SVG graphics on it.

Will the IE9 WebBrowser Control Support all of IE9&#39;s features, including SVG?

Is it possible to set any custom font in every control of the application? And not necessarily runtime ? (i.e. from xml if possible or only once for whole application in JAVA file)


I can set the font for one control from this code.

		Typeface tf = Typeface.createFromAsset(textView.getContext()
				.getAssets(), &quot;fonts/BPreplay.otf&quot;);

		textView.setTypeface(tf);

	}

And the problem with this code is it should be called for every control. And i want to call this or any similar method once, or if possible set the property in xml.  Is it possible?

How do I extract the list of supported Unicode characters from a TrueType or embedded OpenType font on Linux?

Finding out what characters a given font supports

I&#39;m using a barcode font &quot;Free 3 of 9 Extended Regular&quot; and the print out needs to have multiple spaces in some cases, to match the number of characters in the field. Example: 

    *AA-XXXX    *&quot;

 (four spaces follow the item number to make the 12 characters. The barcode reader will give me an error if there are less characters.

`nbsp;` will force multiple spaces, however, IE and Firefox both display those as standard font spaces and do not use the barcode font. The barcode displays as broken up between the non-space characters. (Incidentally, only IE 6 does display `nbsp;` in the proper font.) If I use a regular space, it trims the number of spaces down and displays only one.

Thanks in advance.

Multiple Spaces Between Words in HTML without &amp;nbsp;

I&#39;m using @font-face to embed fonts in my website. First the text renders as the system default, and then (once the font file has loaded presumably) the correct font renders a fraction of a second later.

    [self.view addSubview:factLabel];

Throughout the life of my iOS application, `factLabel` gets a bunch of different values. Some with multiple sentences, others with just 5 or 6 words. 

How can I set up the `UILabel` so that the font size changes so that the text always fits in the bounds I defined?
