Configuring cron jobs on Windows

To setup a Windows machine to run cron.php at a specific time follow the specific instructions below. This can be useful if you are not familiar with Linux/Unix, or if your web host does not offer the ability to run cron jobs; you can run them remotely from your own computer.

Creating a Scheduled Task

1. Open Scheduler
2. Go to Start > Programs > Accessories > System Tools > Scheduled Tasks
3. Double-click Add Scheduled Task
4. The Scheduled Task Wizard will appear. Click Next.
5. Select the program to run. Choose your browser from the list (for example, Internet Explorer or Mozilla Firefox). Click Next.
6. Give the task a Name, such as My Cron Job, and choose the Frequency with which to perform the task (for example, Daily)). Click Next.
7. Choose specific date and time options (this step will vary, depending on the option selected in the previous step). When finished, click Next.
8. Enter your password if prompted. Change the username if required (for example, you´d like the task to run under a user with fewer privileges security reasons). Click Next.
9. On the final page, select the checkbox Open advanced properties for this task when I click Finish and click Finish. Configuring the task
10. Go to the task´s setting page either by checking the checkbox at the end of the last step, or by double-clicking on the task.
11. In the Run box, after the text that is there now (for example, C:\PROGRA~1\MOZILL~1irefox.exe), enter a space and then type the address to your website´s cron.php page in double quotations (for example, C:\PROGRA~1\MOZILL~1irefox.exe http://www.example.com/cron.php).
12. To set a frequency more often than Daily (for example, hourly), click the Schedule tab, then click Advanced. Here you can set options such as Repeat task, every 1 hour for 23 hours. Click Ok when finished.
13. Change the start time on the task to one minute from the current time. This will allow you to test the task and make sure that it is working.
14. When all settings have been configured to your liking, click Apply and OK (note: you may be prompted for your password)

Note: These instructions were written for Windows XP but should be similar in other versions of Windows.

GPGPU stands for General-Purpose computation on Graphics Processing Units

GPGPU stands for General-Purpose computation on Graphics Processing Units, also known as GPU Computing. Graphics Processing Units (GPUs) are high-performance many-core processors capable of very high computation and data throughput.  Once specially designed for computer graphics and difficult to program, today’s GPUs are general-purpose parallel processors with support for accessible programming interfaces and industry-standard languages such as C.  Developers who port their applications to GPUs often achieve speedups of orders of magnitude vs. optimized CPU implementations. The goal of GPGPU.org is to catalog the current and historical use of GPUs for general-purpose computation, and to provide a central resource for GPGPU software developers.

The term GPGPU was coined and GPGPU.org was founded by Mark Harris in 2002 when he recognized an early trend of using GPUs for non-graphics applications.  GPGPU.org has grown from an obscure site visited by few into a popular destination for developers and researchers.

30 Scripts For Galleries, Slideshows and Lightboxes

Family photos, vacation snapshots or creative artistic works: whatever images you have to present, you can present them in a variety of ways. On a big screen, in slide shows or in a thumbnails gallery. However, to convey the message of presented data effectively, it’s important to offer it in an attractive and intuitive way. Furthermore, the presentation itself can make images more valuable and simplify the browsing through hundreds of slides.

There are literally hundreds of solutions for web-based galleries out there. We’ve selected 30 scripts of impressive slideshows, lightboxes and galleries you can use for effective presentations of your images. Most of them don’t have any technical requirements, so you can use them right away. Let’s take a look.

JavaScript techniques

Developers and designers are using more and more JavaScript in modern designs. Sometimes this can be a hindrance to the user and take away from the simplicity of the design, and other times it can add greatly to the user’s experience. The key is a) adding the right amount of JavaScript, and b) using the right JavaScript techniques. We have already collected various JavaScript techniques in the past – now it’s time for a new portion of JavaScript.

Thanks to the Web’s widespread adoption of JavaScript, JavaScript libraries have sprung up to help make design and development easier. Here are a few of the major JavaScript libraries that developers use: jQuery, Prototype, Scriptaculous, mootools, Dojo. These frameworks have thriving communities whose members have developed countless plug-ins that can greatly add to the JavaScript framework.

However, sometimes we need JavaScript solutions that are a little more involved or specific. Here are 75 more handy JavaScript techniques that have made websites much sleeker and more interesting.

Non profit websites

Non profit websites share many of the same best practices as any website. They need to be user friendly, easily navigable, and use appropriate fonts, colors, and other design elements. But often a non profit website needs to offer more than your typical corporate site. A non profit’s website needs to make it easy to find out more about their cause, to donate money, and to become more involved. It needs to make it easy for media contacts to find the information they need and the contact information of key personnel. And it needs to do all this in a way that’s inviting to the organization’s targeted donors and/or volunteers.

Below are a list of best practices for designing non profit websites followed by some examples of non profit websites that are getting things right.

Citra Digital

Komputer digital bekerja dengan angka presisi berhingga, jadi hanya citra dari diskrit yang dapat diolah komputer, citra diskrit = citra digital. Citra digital merupakan suatu array 2 dimensi yang elemennya menyatakan tingkat keabuan dari elemen gambar.

Citra yang dihasilkan direkam datanya bersifat kontinue harus dirubah dahulu menjadi citra digital dengan konversi sehingga dikenal komputer.

Proses tersebut disebut digitasi, yaitu membuat kisi-kisi arah horizontal dan vertical sehingga terbentuk array 2 dimensi.

Digital Vs Analog

Data digital direpresentasikan dalam komputer berbentuk kode seperti binner, decimal. Contoh data digital : WAV, MP3, MID, RMI, BMP, JPG, GIF

Data analog tidak direpresentasikan dalam komputer, semua merupakan fakta, contoh : gelombang suara, gambar. Data analog tersimpan dalam pita kaset.
