Opera, with version 10, is announcing a new feature named Opera Unite which converts any device running this browser into a web server.

It is an open platform where, using its API, developers can create new services/products (with HTML, CSS, JavaScript, SVG and AJAX) which will be served from user’s computers.

Opera Unite

It already comes with various ready-to-use services like:

  • file sharing
  • media player (reach your media from anywhere)
  • web server (host websites, currently static pages but won’t be surprising to see new ones supporting PHP, ASP.NET & others)
  • the lounge (for hosting a chat room)
  • & more..

To read more & download Opera Unite, click here.

P.S. The query at the giveaway announcement post was ending with LIMIT 10, which was not true. It is updated to LIMIT 3.

Server Supervisor, a software (with a web-based interface) for monitoring performance / availability of networks & websites, is giving away 3 licenses ($200/license value) to WebResourcesDepot readers.

Details of the giveaway can be found at the bottom of the post.

What is Server Supervisor?

It is a software, which can be managed from an easy to use & beautiful web interface (built with Flex), to monitor any network & website for minimum downtime.

Server Supervisor

Resources to be monitored includes:

  • Ping, connect, DNS
  • HTTP, HTTP Content, HTTP Transaction, IIS Status, Apache Status, Process
  • MySQL, MSSQL, Oracle
  • FTP, SMTP, POP3, IMAP
  • CPU, Free memory, Page file, Free disk space, Network usage, File system (via WMI and SNMP protocols)

There is a smart "action upon problem detection" logic behind the software. When a failure is detected, notifications can be sent, any applications can be launched (for fixing the problem) & other monitors can be enabled-disabled.

The levels of failures can be configured for each monitored resource & notifications can be sent to email, SMS and instant messengers (ICQ, Yahoo and MSN).

Server Supervisor Report

With a built-in database, Server Supervisor keeps all the logs it generates & presents them with a powerful statistics analysis component which enables you to generate custom reports & get them to your e-mail periodically.

A 14 day free trial is offered at the products website. So, you can easily give the software a try.

Info: The software is compatible with Microsoft Windows 2000/XP/Server 2003/Vista/Server 2008.

Info: Every user / developer has different experiences. Any more tips that you share in the comments will be appreciated.

"Why is my website slow?" is a popular question. And it is a vital problem for a website.

Faster the website, happier & more the visitors. That's a well-known fact.

There are several factors that may slow a website. In general, all of them can be solved. This just depends on how much effort you can spend on it.

How much time do you have?

You may not have enough time to spend on speeding up your website. Depending on your free time, you may choose the steps to apply like mentioned below:

  • I have very limited time: Apply step-1, step-2, step-4 & step-5 (only the compression parts) and step-6.
  • I have some time: Apply all of them except step-3 & step-8.
  • I rule the time: Go with them all.

Improve Website Speed

Most of the tips are the ones that you probably know. So, you can use the list as a checklist (which it normally is in my "customer notes sheet" : ) ).

Here are the tips:

1. Get A Fast & Less-Loaded Web Server

This is a must. Whatever you do to make your website faster, if it is served slow, there's nothing to do.

Make sure that the server your website is hosted has low ping values & it is not over-loaded. Specially if you've a database and/or using dynamic files (like asp, asp.net, php, ruby..) server over-load can kill the performance.

If you've a simple website with few visitors then shared hosting is ok. For a website getting popular, think of a VPS with guaranteed RAM & CPU usage. If the website is already popular, a dedicated server will be the best performing one.

2. Know When To Use GIF, JPG & PNG Files. 

Playing with the quality of images will dramatically lower the sizes of them while they will still be looking good.

GIF is suitable for images with few colors like logos, text & line art. When saving a GIF file, make sure you use a small color pallette (learn more).

JPG is good for images with lots of colors & details like photographs. Decrease the quality of a JPG image before saving. It will still look good for a web image (learn more).

PNG, a format specially for websites, has great quality – both transparent & non-transparent – is specially functional when you're in need of quality transparent images. Don't forget that IE6 has problems in displaying them (learn more).

3. Use XHTML – No Tables

This is easy to tell but may be harder to implement for anyone that has few experience with XHTML.

The thing is, tables are rendered slower than DIVs by browsers. You can do more with less code & no need to say it is much better to be compatible with any browser (including mobile browsers), in means of SEO, etc..

Update: There may be cases when using tables are much more logical like "tabular data". You may have to code a lot for creating the look of a simple 5 columned table. Don't do that & use tables when needed.

What is tried to be mentioned here is, use XHTML rather than tables in general. But don't try to draw images with XHTML.

4. Use CSS Smartly & Compressed

  • Mention every style in CSS files.
  • Find the common properties in objects, define them once & try not to repeat them.
  • If using a significant amount of totally different properties for a specific page, define them in another CSS file & only include on that page. So users viewing other pages won't need to download those properties.
  • Compress your CSS file (you may try this, this or this).

5. Merge & Compress JavaScript Files

Try merging JavaScript files prevent multiple includes (see step 6).

If a JavaScript file will be used only in few pages, try to include them inside those pages only (like CSS in step 4).

Compress JavaScript files. It lowers the size seriously & doesn't have any bad effects on your side. This & this are some of the popular compressors.

6. Manage Included Files Better

There may be several files included in webpages like CSS files, JavaScript files and other JavaScript files for statistic services, social bookmarking sites, widgets & more.

Try to decrease the number of these files:

  • If using digg-reddit-like voting widgets, don't use them in stories that won't hit the frontpage & remove the ones that were submitted few days ago as they won't have any help after sometime.
  • Use only 1 statistic service if possible. Every web-based service requires new files to be installed & they are called each time a page is loaded.
  • Host files on your side & don't use web addresses as file paths.
    • If you're using any JS frameworks like jQuery or MooTools, don't call the .js files from their websites but download & upload them to your website.
    • Don't try to call any file from a web address like "http://.." as this always requires dns queries to be done & will work slower.
  • PHP Speedy (WRD post)is a very effective solution that does all the combining & compressing automatically. You may want to try it.

7. Use HTTP Compression

HTTP compression is one of the most effective step with a little effort.

Today, almost every browser & web server supports HTTP compression. Using it, your files are sent to the visitor compressed & un-compressed on their side & you can have up to 90% success for the text based files (like HTML).

You have 2 popular choices with this:

8. Better Coding

This is for websites which does not use any ready-to-use systems like WordPress, Drupal, ExpressionEngine or similar (if you're using these then you're lucky as they are already well-coded).

Besides the better XHTML & CSS coding, the dynamic coding of the website directly effects the performance.

As you can guess, this is a huge subject. But there are some major things like:

  • Seperate the static & dynamic content. This will help writing less-code.
  • Create smart & effective functions. For ex: if you're going to use a user's name & birthdate at the same page, don't run 2 queries or functions, your function must call 2 of them. Simply, try to do everything once.
  • Connect to the database as few as you can & once connected, call only the data you need.
  • Try to keep database sizes small. If you've a large database, sometimes seperating it into several databases perform better, specially for the data which is reached not so often. From the server's point of view: 4-250mbs of dbs perform better than 1-1gb of db.

9. Cache Webpages

Caching is a superb way of decreasing the stress on the server by running more static files & less queries. It simply saves a static, HTML version of the page to be displayed & displays that file rather than the dynamic one.

For CMS applications like WordPress, there are already ready-to-use caching plugins (like WP-Cache). For PHP, here is a great article from SitePoint.

A small note, caching can also be done at the web server level. But if you're on a shared hosting account, you better be lucky to have it on.
