Monitoring your computer’s Internet activity is a powerful tool, enabling you to: keep an eye on background processes reveal viruses and other malware expose unauthorized access monitor running programs log process activity ..and much more. The best part? It’s super-easy. Here’s how I do it on Win XP: Open the command prompt and type “netstat -n 5 > scan.txt” After a minute or two (or any amount of time), press Ctrl+C to stop monitoring Type “scan.txt” to open the log […] Continue reading »
Recently, I spent some time addressing a few of the performance issues pointed out by Yahoo!’s very useful YSlow extension for Firebug. Working on performance tip #3, Add an Expires or a Cache-Control Header, I encountered some difficulty while trying to get the JavaScript used by Mint to cache as desired. Apparently, the HTAccess directives used to cache my other scripts do not effect the two PHP-generated JavaScript files used by Mint. Although I am not entirely certain, I suspect […] Continue reading »
Recently, while restoring the popular Jupiter! WordPress theme, which several readers use to “skin” the Perishable Press website, I found myself searching for a simple, effective JavaScript technique for toggling element visibility. Specifically, I needed to accomplish the following design goals: Continue reading »
As one who takes full advantage of the custom dictionary in Firefox, I occasionally find myself adding nonexistent or misspelled words to the dictionary by accident. Not wanting to deal with a false negative down the road, I always take the time to stop what I’m doing, locate the custom dictionary, and remove the erroneous term. Finally getting sick of trying to remember the esoteric location in which Firefox stores the personal dictionary, I decided to make a few notes […] Continue reading »
In this tutorial, I present an easy way to add a little extra flair to your site by adding some dynamic clock functionality. Using unobtrusive JavaScript, a bit of (X)HTML markup, and a dash of PHP (optional), we will create a dynamic clock that degrades gracefully to a static date/time-stamp when JavaScript is unavailable. No need to get all verbose with this one, so let’s dive right in.. Continue reading »
As Firefox continues to grow in popularity, it is inevitable that more and more users will install plugins such as Adblock and Adblock Plus. As we know, such extensions work by filtering site contents through a list of predefined wildcard directives and other rules. Users may also customize the block-list by right-clicking on unwanted images or even subscribing to an automated filterset updater. Apparently, a significant number of Firefox users employ these extensions to help control the relentless flood of […] Continue reading »
I realize that probably everybody already knows this elementary and absolutely dead-simple JavaScript tip, but I was surfing around the other day and encountered a page that made great use of some auto-highlighted textarea content. The idea is simple, include a snippet of JavaScript to enable users to automatically highlight/select upon focus any chunk of text located within a form input or textarea element. Continue reading »
Last week, I finally got around to upgrading to Mint 2.14. The new version is quite impressive, and well worth the time (and cash) spent upgrading. In the process, however, one of my favorite, most heavily used bookmarklet things ceased to work. Before the upgrade, I had been enjoying the highly useful Refresh-All bookmarklet by Jonathan Snook. Snook’s Mint-refresh bookmarklet made it super-easy to update all Mint data panels without having to refresh the entire page. Using the bookmarklet is […] Continue reading »
By now, everyone is familiar with the Yahoo Developer Network’s 14 best-practices for speeding up your website. Certainly, many (if not all) of these performance optimization tips are ideal for high-traffic sites such as Yahoo or Google, but not all of them are recommended for smaller sites such as Perishable Press. Nonetheless, throughout the current site renovation project, I have attempted to implement as many of these practices as possible. At the time of this writing, I somehow have managed […] Continue reading »
After switching Perishable Press to its current home at A Small Orange, I began noticing an unusual problem with referrer data displayed in Mint. Specifically, the first item recorded in the XXX Strong Mint data panel — for both “Most Recent” and “Repeat” views — displayed several thousand hits for various site resources, all reporting the following IP address: Continue reading »
In the Beginning.. Over a year ago, I posted an article recommending over fifty essential Firefox extensions. Excited to have discovered the miraculous joys of extending Firefox with such amazing functionality, I loaded my primary copy of Firefox with just about every potentially useful extension that I could find. Several weeks were spent playing with new features, customizing preferences, and configuring options to gel together in an orchestrated chorus of blissful browser harmony. After experiencing the functional firepower of my […] Continue reading »
Recently, after researching comment links for an upcoming article, I realized that my default <input /> values were being submitted as the URL for all comments left without associated website information. During the most recent site redesign, I made the mistake of doing this in comments.php: … <input class="input" name="url" id="url" value="[website]" onfocus="this.select();" type="text" tabindex="3" size="44" maxlength="133" alt="website" /> … Notice the value="[website]" attribute? It seemed like a good idea at the time — I even threw in a nice […] Continue reading »
..Or something. Frankly, I just needed an excuse to post these steaming little beauties online. Please note that I don’t lay claim to most of these browser bookmarklet/favelet tricks, but I do find them extremely useful. They are posted here for the sake of convenience and for reference purposes, so use at your own risk (i.e., I am not responsible if they crash your browser). Although I use most of these bad boys with Firefox, I wouldn’t be terribly surprised […] Continue reading »
Clean, easy, effective. You don’t need no stinking JavaScript to preload your images. Nope. Try some tasty CSS and (X)HTML instead! Here’s how to do it with only two easy steps.. Step 1 — Place this in your CSS file: div#preloaded-images { position: absolute; overflow: hidden; left: -9999px; top: -9999px; height: 1px; width: 1px; } Step 2 — Place this at the bottom of your (X)HTML document: <div id="preloaded-images"> <img src="https://perishablepress.com/image-01.png" width="1" height="1" alt="" /> <img src="https://perishablepress.com/image-02.png" width="1" height="1" alt="" […] Continue reading »
Even with all the fancy-pants new features found in Windows XP and now Vista, Microsoft Windows 98 (Second Edition) remains our favorite Windows-flavored operating system. We love it so much, we still use it on one of our trusty laptops. Over the years, we have discovered several very useful functions available via the command line or even the “Run” prompt (Start → Run…). Anyway, without spending too much time researching or explaining these wonderful tools, we figured posting the information online may […] Continue reading »
In this article, we extrapolate our favorite CSS-compression technique for JavaScript. Below, we outline the steps required to auto-compress your JavaScript documents via gzip and PHP. Two different compression methods are presented. The first method does not require htaccess, but rather involves the manual editing of JavaScript files. The second method employs htaccess to do all the work for you, thus requiring much less effort to implement. In either case, the result is the same: automatically compressed content delivered only […] Continue reading »
