Speaking of Flippa, something is going on. Release? Not sure, but Sitepoint Marketplace is down for an upgrade at the same time as Flippa.com. According to SP it’ll last about three hours, which in terms of a top 1,000 site is quite a while.
If you use the Sitepoint Marketplace to buy and sell online, prepare for a big change. Sitepoint is flipping things upside-down soon, and moving the marketplace to Flippa.com. Many people are saying WTF to Flippa, and with good reasons. Is this too much at once?
This huge list of 76 script directories took several hours to compile, but it’s a goldmine for anyone selling online software. This is one mega list of script directories that let you submit your PHP scripts, turnkey scripts, and other website scripts. Most are free, some are paid or offer paid options. Some of these script sites get tons of traffic. Getting your products listed on the right script directories pays off.
The nofollow tag (as it’s commonly referred to), is an HTML attribute proposed by Matt Cutts of Google and Jason Shellen of Blogger.com in 2005. It is a recommendation on behalf of search engines to add a special identifier to links that shouldn’t be counted towards search results. For instance, unmoderated blog comments might be a candidate for nofollow attribute.
Linux sometimes dumps a huge file when a script crashes. These core files can build up and eat away valuable disk space. Some other methods of deleting core files will damage your server. Here are a few simple commands I use to find and delete these core dump files safely.
I use a lot of different software in my job, but there are five software tools in particular that I can do nearly all of my Web development with. The best part is they are allcompletely free applications. You can download and install everything you need to be up and coding in under 30 minutes.
TinyMCE is a free WYSIWYG editor with two visual components - themes and skins. TinyMCE themes are very complex to customize but you can make your own TinyMCE theme. If you just want to customize the look & feel a little bit, you’re better off creating a TinyMCE skin.
Creating great products is easy if you identify a problem. Like many others I’m willing to pay for a good solution if the need is great enough. Identifying the deepest problem for your customers and developing a great solution is the recipe for a successful product.
I’ll admit this is one project I wasn’t even aware of. The Wordpress blog just mentioned the sister project BuddyPress, which takes the WP architecture to a new level with a complete social networking platform.
Google has a history of commemorating holidays and historic events by showing a different logo for the day, and this is the best yet! Today is Samuel Morse’s birthday (you know, Morse code?), and they spelled out Google in the famous dash-dot character encoding.
There are thousands of free scripts to speed up development. Established PHP frameworks and JavaScript libraries abound. It’s expensive to reinvent the wheel, and pointless besides. But when is it legal to use free code in your commercial apps, and how will it affect your project?
The Apache Web server supports URL rewriting with the mod_rewrite engine. Placing custom rules in an .htaccess file lets you do all sorts of useful things to keep your URLs tidy. One really handy thing you can do for search engines and visitors is redirecting traffic from www to non-www version of your domain (and vice versa).
Displaying remote data in your custom Firefox toolbar makes a lot of neat things possible. If your Firefox add-on needs to fetch some data from another URL, it can be done easily with XMLHttpRequest.
What is XMLHttpRequest? The XMLHttpRequest object enables client-server requests in JavaScript. If you’re writing Ajax enabled scripts, fetching remote data in a Firefox extension, or pulling data from another URL in any JavaScript app then XMLHttpRequest is needed.
This is a completely portable PHP script that fetches similar threads from a vBulletin forum. It does not require global.php or any other vBulletin scripts to run. The script uses full score matching, and supports search engine friendly URLs made by vBSEO and other custom formats.
A good friend recently provided me with some dead-simple instructions on how to use GPG in linux so we could share a few sensitive files. I have edited them slightly and with his permission I will share them with you.
I just compared Google referrals to PageRank on 37 different Websites, and here are the results. The numbers are pretty amazing. If PageRank does mean anything, it certainly doesn’t mean good search performance…
Google Toolbar has finally outgrown it’s usefulness. After years of using the Firefox add-on, I permanently removed it from all my computers. The PageRank display was my only reason for using the toolbar. Now PageRank isn’t very useful, the toolbar slows down browsing, and I even saved a meager 4.7MB of memory.
Whatever Google is up to with PageRank lately, it’s quickly losing my interest. PageRank was never meant to be a reliable measure of search engine performance, but it was usually “in the neighborhood”. After the last few PageRank updates, I’ve found myself relying almost completely on other tools due to the extreme gaps I continue to observe.
I was recently using phpMyAdmin to export some records from an URL shortener I’m working on. As usual I verified that “Complete inserts” and “Extended inserts” were enabled for the SQL dump. Why? Using both of these options reduces your SQL filesize and explicitly declares each column name.
