Windows or Linux hosting – which is best for you?

<b>Linux</b> (and its close relation Unix) and <b>Windows 2003</b> (and its close cousin Windows NT) are types of software (known as operating systems) that web servers use to do the kind of things that web servers do. You do not need to know any real detail of either to make a decision as to which you need but here a few guidelines.<br> <br> <b>"Just because you use a windows desktop PC doesn't mean you have to opt for Windows web hosting (and the reverse is true as well). The operating system you use on your desktop has little to do with your choice of web hosts. As long as you understand how to use your FTP or web publishing software, your can use either operating system"</b>.<br> <br>

Controlling DNS prefetching

<br> As of version 3.5, Firefox supports DNS prefetching. This is a feature by which Firefox proactively performs domain name resolution on both links that the user may choose to follow as well as URLs for items referenced by the document, including images, CSS, JavaScript, and so forth.<br> <br> This prefetching is performed in the background, so that the DNS is likely to already have been resolved by the time the referenced items are actually needed.  This reduces latency when, for example, the user actually clicks a link.<br> <h2> Background</h2> DNS requests are very small in terms of bandwidth, but latency can be quite high, especially on mobile networks.  By speculatively prefetching DNS results, latency when, for example, the user clicks a link can be reduced significantly (on the order of a second, in some cases).<br>

Heartbleed bug: What you need to know

<div class="separator" style="clear: both; text-align: center;"> <a href="http://upload.wikimedia.org/wikipedia/commons/thumb/d/dc/Heartbleed.svg/411px-Heartbleed.svg.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><span style="font-family: Arial, Helvetica, sans-serif;"><img border="0" height="320" src="http://upload.wikimedia.org/wikipedia/commons/thumb/d/dc/Heartbleed.svg/411px-Heartbleed.svg.png" width="255" /></span></a></div> <span style="font-family: Arial, Helvetica, sans-serif;">The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure it.</span><br /> <span style="font-family: Arial, Helvetica, sans-serif;"><br /></span> <span style="font-family: Arial, Helvetica, sans-serif;">You are likely affected if you configured and run an SSL-enabled website, meaning that you can access it using the https:// prefix instead of http://. You will need to patch the libraries in your system and replace the certificates and keys that may have been compromised. Please notice that remote access using ssh is NOT affected.</span><br /> <span style="font-family: Arial, Helvetica, sans-serif;"><br /></span> <span style="font-family: Arial, Helvetica, sans-serif;">OpenSSL versions from 1.0.1 through 1.0.1f (inclusive) are vulnerable and make it possible to steal information, including everything from the encrypted content and to the secret key used for the encryption. The attack is also indetectable.</span><br /> <span style="font-family: Arial, Helvetica, sans-serif;"><br /></span> <span style="font-family: Arial, Helvetica, sans-serif;">This security issue has been described in detail on the following page:</span><br /> <a href="http://heartbleed.com/" target="_blank"><span style="font-family: Arial, Helvetica, sans-serif;">http://heartbleed.com/</span></a><br /> <span style="font-family: Arial, Helvetica, sans-serif;"><br /></span> <br /> <h2> <span style="font-family: Arial, Helvetica, sans-serif;

This could be easier done by people who are friends with the person they’re trying to hack.<br> <ul> <li>The first step would be to get your friend’s Facebook email login. If you don’t already know it, try looking on their Facebook page in the Contact Info section.</li> <li>Next, click on <strong>Forgotten your password?</strong> and type in the victim’s email. Their account should come up. Click <strong>This is my account</strong>.</li> <li>It will ask if you would like to reset the password via the victim’s emails. This doesn’t help, so press <strong>No longer have access to these?</strong></li> <li>It will now ask <strong>How can we reach you?</strong> Type in an email that you have that also isn’t linked to any other Facebook account.</li> <li>It will now ask you a question. If you’re close friends with the victim, that’s great. If you don’t know too much about them, make an educated guess. If you figure it out, you can change the password. Now you have to wait 24 hours to login to their account.</li> <li>If you don’t figure out the question, you can click on <strong>Recover your account with help from friends</strong>. This allows you to choose between three and five friends.</li></ul>
