			<content:encoded><![CDATA[<p>If you are getting a message like this:</p>

<div class="wp_syntax"><div class="code"><pre class="python" style="font-family:monospace;"><span style="color: #66cc66;">&gt;&gt;&gt;</span> <span style="color: #ff7700;font-weight:bold;">import</span> cx_Oracle

<p>It means you are having issues with <strong>ELF </strong>(<a href="http://en.wikipedia.org/wiki/Executable_and_Linkable_Format">Executable and Linkable Format</a>)</p>
<p>How to solve em?</p>
<p>First, locate the path to <em>libclntsh.so.11.1</em> (usually in <em>/usr</em>):</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #7a0874; font-weight: bold;">&#91;</span>root<span style="color: #000000; font-weight: bold;">@</span>zaguan importaFHdesdeRoble<span style="color: #7a0874; font-weight: bold;">&#93;</span><span style="color: #666666; font-style: italic;"># find / -name &quot;libclntsh.so.11.1&quot;</span>
<span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>oracle<span style="color: #000000; font-weight: bold;">/</span><span style="color: #000000;">11.1</span><span style="color: #000000; font-weight: bold;">/</span>client64<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so.11.1
<span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib64<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so.11.1</pre></div></div>

<p>Note the presence of two files. Lets check wether they are for 32bits or 64bits:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #7a0874; font-weight: bold;">&#91;</span>root<span style="color: #000000; font-weight: bold;">@</span>zaguan importaFHdesdeRoble<span style="color: #7a0874; font-weight: bold;">&#93;</span><span style="color: #666666; font-style: italic;"># file /usr/lib/oracle/11.1/client64/lib/libclntsh.so.11.1</span>
<span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>oracle<span style="color: #000000; font-weight: bold;">/</span><span style="color: #000000;">11.1</span><span style="color: #000000; font-weight: bold;">/</span>client64<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so.11.1: ELF <span style="color: #000000;">64</span>-bit LSB shared object, AMD x86-<span style="color: #000000;">64</span>, version <span style="color: #000000;">1</span> <span style="color: #7a0874; font-weight: bold;">&#40;</span>SYSV<span style="color: #7a0874; font-weight: bold;">&#41;</span>, not stripped
&nbsp;
<span style="color: #7a0874; font-weight: bold;">&#91;</span>root<span style="color: #000000; font-weight: bold;">@</span>zaguan importaFHdesdeRoble<span style="color: #7a0874; font-weight: bold;">&#93;</span><span style="color: #666666; font-style: italic;"># file /usr/lib64/libclntsh.so</span>
<span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib64<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so: ELF <span style="color: #000000;">32</span>-bit LSB shared object, Intel <span style="color: #000000;">80386</span>, version <span style="color: #000000;">1</span> <span style="color: #7a0874; font-weight: bold;">&#40;</span>SYSV<span style="color: #7a0874; font-weight: bold;">&#41;</span>, not stripped</pre></div></div>

<p>If your system is 64 bits (check it out with <em>uname -a</em>) you should be using the  ELF 64-bit LSB shared object.</p>
<p>So, you can just:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">mv</span> <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib64<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so.11.1 <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib64<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so.11.1__32bits
<span style="color: #c20cb9; font-weight: bold;">cp</span> <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>oracle<span style="color: #000000; font-weight: bold;">/</span><span style="color: #000000;">11.1</span><span style="color: #000000; font-weight: bold;">/</span>client64<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so.11.1 <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib64<span style="color: #000000; font-weight: bold;">/</span>libclntsh.so.11.1</pre></div></div>

<p>And now, you will be able to import Oracle library from python:</p>

<div class="wp_syntax"><div class="code"><pre class="python" style="font-family:monospace;"><span style="color: #808080; font-style: italic;"># python</span>

<span style="color: #66cc66;">&gt;&gt;&gt;</span></pre></div></div>

<p>Or, if you want to do it &#8220;the right way&#8221;. Put this in a script.sh file and alter</p>

			<content:encoded><![CDATA[<p>La verdad es que las <strong>tildes </strong>siempre son una lata en programación y en consultas a bases de datos <strong>MySQL</strong><br />
.<br />
Imagina que tienes una tabla con los siguientes valores</p>
<table id="tablamysql">
<tr>
<td>ID</td>
<td>value</td>
</tr>
<tr>
<td>1</td>
<td>Óscar</td>
</tr>
<tr>
<td>2</td>
<td>Oscar</td>
</tr>
</table>
<p>Antes de empezar a hacer queries a la BD, nos aseguraremos de que se tiene en cuenta el utf8:</p>

<div class="wp_syntax"><div class="code"><pre class="mysql" style="font-family:monospace;">mysql<span style="color: #CC0099;">&gt;</span> <span style="color: #990099; font-weight: bold;">set</span> name <span style="color: #008000;">'utf8'</span><span style="color: #000033;">;</span></pre></div></div>

<p>Observa lo que sucede si haces un select distinct a secas:</p>

<div class="wp_syntax"><div class="code"><pre class="mysql" style="font-family:monospace;">mysql<span style="color: #CC0099;">&gt;</span> <span style="color: #990099; font-weight: bold;">SELECT</span> <span style="color: #990099; font-weight: bold;">DISTINCT</span> <span style="color: #990099; font-weight: bold;">value</span> <span style="color: #990099; font-weight: bold;">from</span> <span style="color: #990099; font-weight: bold;">table</span><span style="color: #000033;">;</span>
<span style="color: #CC0099;">+--------+</span>
<span style="color: #CC0099;">|</span> <span style="color: #990099; font-weight: bold;">value</span>   <span style="color: #CC0099;">|</span>
<span style="color: #CC0099;">+--------+</span>
<span style="color: #CC0099;">|</span> Oscar   <span style="color: #CC0099;">|</span>
<span style="color: #CC0099;">+--------+</span></pre></div></div>

<p>Los campos de tipo textual (<em>CHAR</em> y <em>VARCHAR</em> por ejemplo) son <b>case-insensitive</b> y <b>accent-insensitive</b>. Esto es, tanto <em>OSCAR</em> como <em>Óscar</em>, <em>Oscar</em> y <em>ÓSCAR</em> son lo mismo para mysql.</p>
<p>Si queremos que nos distinga esto (que <em>Óscar</em> y <em>Oscar</em> sean distintos), tenemos la opción de usar el modificador MD5 o, más simple, el modificador <em>BINARY</em></p>

<div class="wp_syntax"><div class="code"><pre class="mysql" style="font-family:monospace;">mysql<span style="color: #CC0099;">&gt;</span> <span style="color: #990099; font-weight: bold;">SELECT</span> <span style="color: #990099; font-weight: bold;">DISTINCT</span> <span style="color: #990099; font-weight: bold;">binary</span> <span style="color: #990099; font-weight: bold;">value</span> <span style="color: #990099; font-weight: bold;">from</span> <span style="color: #990099; font-weight: bold;">table</span><span style="color: #000033;">;</span>
<span style="color: #CC0099;">+--------+</span>
<span style="color: #CC0099;">|</span> <span style="color: #990099; font-weight: bold;">value</span>   <span style="color: #CC0099;">|</span>
<span style="color: #CC0099;">+--------+</span>
<span style="color: #CC0099;">|</span> Oscar   <span style="color: #CC0099;">|</span>
<span style="color: #CC0099;">+--------+</span>
<span style="color: #CC0099;">|</span> Óscar   <span style="color: #CC0099;">|</span>
<span style="color: #CC0099;">+--------+</span></pre></div></div>

<p><strong>ENGLISH:</strong><br />
Distinct works depending on column type.<br />
Varchar is case insensitive and accent agnostic while comparing,<br />
Binary string (Binary) columns require byte-to-byte match.<br />
Keyword BINARY in front of an expression, makes it a byte-to-byte<br />
comparison.</p>

4. Descargamos e instalamos el complemento. Se reiniciará Firefox<br />
5. Herramientas > Opciones RefControl&#8230;<br />
6. Añadir sitio. En sitio ponemos imageshack.us<br />

<h3>Eliminar ranitas de imageshack en CHROME</h3>
<p>En el icono del escritorio de Google Chrome boton derecho -> Propiedades<br />
En la linea Destino: &#8220;C:\Archivos de programa\Google\Chrome\Application\chrome.exe&#8221;<br />
Al final del todo tenemos que añadir &#8220;&#8211;no-referrers&#8221; (importante añadir un espacio)<br />
con lo cual la linea Destino quedaria asi:<br />
&#8220;C:\Archivos de programa\Google\Chrome\Application\chrome.exe&#8221; &#8220;&#8211;no-referrers&#8221;</p>

			<content:encoded><![CDATA[<p>If you are getting this error in <b>WordPress 3</b>:<br />
<em>An Unexpected HTTP Error occurred during the API request</em></p>
<p>Edit your <em>wp-includes/class-http.php</em></p>
<p>Search this:</p>

<div class="wp_syntax"><div class="code"><pre class="php" style="font-family:monospace;"><span style="color: #000088;">$defaults</span> <span style="color: #339933;">=</span> <span style="color: #990000;">array</span><span style="color: #009900;">&#40;</span>

			<span style="color: #0000ff;">'timeout'</span> <span style="color: #339933;">=&gt;</span> apply_filters<span style="color: #009900;">&#40;</span> <span style="color: #0000ff;">'http_request_timeout'</span><span style="color: #339933;">,</span> <span style="color: #cc66cc;">5</span><span style="color: #009900;">&#41;</span><span style="color: #339933;">,</span></pre></div></div>

<p>And change it to:</p>

<div class="wp_syntax"><div class="code"><pre class="php" style="font-family:monospace;"><span style="color: #000088;">$defaults</span> <span style="color: #339933;">=</span> <span style="color: #990000;">array</span><span style="color: #009900;">&#40;</span>

<p>Should work now <img src='http://www.leccionespracticas.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>
<p>If it does not:</p>
<p>Install <a href="http://wordpress.org/extend/plugins/core-control/">Core control plugin</a><br />
Head to it&#8217;s menu under <em>Tools</em>, Select the <em>HTTP Access module</em>, Save the page.<br />
Head over to the new HTTP tab along the top of the page.</p>
<p>What transports is it using? Does it make a difference if you disable the currently active transport? </p>
<p>Usual transports are (ordered by priority of use):</p>

<div class="wp_syntax"><div class="code"><pre class="php" style="font-family:monospace;">PHP HTTP Extension	
cURL	
PHP Streams	
PHP <span style="color: #990000;">fopen</span><span style="color: #009900;">&#40;</span><span style="color: #009900;">&#41;</span>	
PHP <span style="color: #990000;">fsockopen</span><span style="color: #009900;">&#40;</span><span style="color: #009900;">&#41;</span></pre></div></div>

<p>Next to each transport you will find if they are <em>Available</em> or <em>Not available</em>.</p>
<p>If the <em>cURL transport</em> is the currently active one, Disable that. Should work now!<br />
<img src="http://img88.imageshack.us/img88/7412/curltransportwordpressc.jpg" width="550px" alt="curl transport disabled wordpress core control" /></p>

			<content:encoded><![CDATA[<p>Currently, only up to <b>500 rows of Analytics table data can be exported at a time into CSV format</b>. If you need to export larger data sets, like exporting all keywords that sent traffic to your site, you can export multiple times as long as each batch contains at maximum 500 rows.</p>
<p>If you have thousands of rows that require multiple exports, you can use the convenient workaround below to export all your rows in one go.</p>
<p>   1. Go the report that contains the data you want to export.</p>
<p>   2. Append the query parameter &#8216;limit&#8217; to the url (to the end of URL!), and hit enter to reload the report. The limit parameter is needed prior to every report export.<br />
      For example:<br />
      <code></p>
<p>https://www.google.com/analytics/reporting/top_content?id=14120873&#038;pdr=20090101-20091231&#038;cmp=average&#038;trows=5000&#038;gdfmt=nth_day#lts=1268387872421&#038;limit=50000</p>
<p>      </code></p>
<p>   3. Hit &#8216;Enter&#8217; and visually confirm that the report now has the new parameter appended to it. While <b>there won&#8217;t be any visible difference in user interface</b>, exporting will now yield more rows.</p>
<p>   4. Select the Export tab, and <b>click &#8216;CSV&#8217; (not the option that says &#8216;CSV for Excel&#8217;)</b>.<br />
   5. The exported data should contain all the rows from your Analytics table.</p>

			<content:encoded><![CDATA[<p><a href="http://www.httpwatch.com">httpwatch</a> is an HTTP viewer and debugger that integrates with IE and Firefox to provide seamless HTTP and HTTPS monitoring without leaving the browser. This kind of software is usually known as <em>sniffer</em>.</p>

<h3>Why do you need an HTTP Viewer or Sniffer?</h3>
<p>All web applications make extensive use of the HTTP protocol (or HTTPS for secure sites). Even simple web pages require the use of multiple HTTP requests to download HTML, graphics and javascript. The ability to view the HTTP interaction between the browser and web site is crucial to these areas of web development:<br />
* Troubleshooting<br />
* Performance tuning<br />
* Verifying the security of a site</p>
<h3>How can HttpWatch  help?</h3>
<p>HttpWatch integrates with Internet Explorer and Firefox browsers to show you exactly what HTTP traffic is triggered when you access a web page. If you access a site that uses secure HTTPS connections, HttpWatch automatically displays the decrypted form of the network traffic.</p>
<p><img src="http://www.httpwatch.com/images/ebay.png" width="550px" alt="httpwatch" /></p>
<p>Conventional network monitoring tools just display low level data captured from the network. In contrast, HttpWatch has been optimized for displaying HTTP traffic and allows you  to quickly see the values of headers, cookies, query strings and more&#8230; </p>
<p>HttpWatch also supports non-interactive examination of HTTP data. When log files are saved, a complete record of the HTTP  traffic is saved in a compact file. You can even examine log files that your customers and suppliers have recorded using the <b>free Basic Edition</b>.</p>

			<content:encoded><![CDATA[<p>The other day I tried to <strong>cite</strong> one article in one of my papers which contained the acronym “RANSAC” inside its title. I added the <strong>BibtTeX reference </strong>to the references’ file:</p>
<p>El otro día intenté <strong>citar </strong>en uno de mis artículos un paper que contenía el acrónimo “RANSAC” en su título. En mi fichero de <strong>referencias</strong> <strong>BibTeX </strong>añadí la siguiente entrada:</p>

<div class="wp_syntax"><div class="code"><pre class="latex" style="font-family:monospace;">@InProceedings<span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">ref01,
   AUTHOR = { xxx </span><span style="color: #E02020; ">}</span>,
   booktitle = <span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">xxx</span><span style="color: #E02020; ">}</span>,
   TITLE = <span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">xxx RANSAC BibTeX xxx</span><span style="color: #E02020; ">}</span>,
   year = <span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">2010</span><span style="color: #E02020; ">}</span>,
<span style="color: #E02020; ">}</span></pre></div></div>

<p>After compiling the file I was surprised that in the pdf file the acronym appeared with <strong>lower case</strong> letters instead of <strong>capital letters</strong>. The solution to this problem consists in telling the <strong>LaTeX </strong>compiler to write the acronym as it is written in the bib file. In order to do this we just need to put the word (or letters) within additional braces.</p>
<p>Cuando compilé me sorprendió que en el pdf el acrónimo apareciera en letras <strong>minúsculas</strong> en lugar de en <strong>mayúsculas</strong>, como yo lo había escrito en el fichero de referencias. Para evitar este problema hay que decirle al compilador de <strong>LaTeX</strong> que escriba el título textualmente. Esto lo hacemos poniendo entre llaves adicionales la palabra que queremos que escriba en <strong>mayúsculas</strong>.</p>

<div class="wp_syntax"><div class="code"><pre class="latex" style="font-family:monospace;">@InProceedings<span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">ref01,
   AUTHOR = { xxx </span><span style="color: #E02020; ">}</span>,
   booktitle = <span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">xxx</span><span style="color: #E02020; ">}</span>,
   TITLE = <span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">xxx {RANSAC</span><span style="color: #E02020; ">}</span> <span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">B</span><span style="color: #E02020; ">}</span>ib<span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">T</span><span style="color: #E02020; ">}</span>e<span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">X</span><span style="color: #E02020; ">}</span> xxx<span style="color: #E02020; ">}</span>,
   year = <span style="color: #E02020; ">{</span><span style="color: #2020C0; font-weight: normal;">2010</span><span style="color: #E02020; ">}</span>,
<span style="color: #E02020; ">}</span></pre></div></div>
