JPEG vs GIFs

JPEG versus GIFs? When to use or save my file using GIF or JPEG/JPG?

Jpegs and gifs are the most commonly used graphic formats on the web. Each has it’s unique advantages and disadvantages. The material covered in this article will help you decide which format is more appropriate for your images. A general rule of thumb; use gifs for illustrations, clip art, and images with large areas of flat color, use jpgs for photographs and images with continuos tones.

Prepare Your Images
Your images should be RGB, 24bit when you begin. It doesn’t matter where they come from, digital camera, scanner, clipart, custom illustrations, or from another document. Be sure to keep an original around for any changes you want to make later. I recommend keeping everything in Photoshop format, so you can retain all your original information, and layers you may have. If you don’t use Photoshop, keep an original as a tiff, pict, or bmp. (For all you graphic designers out there, people really do use pict for something!) This will give you the most flexibility. I mention this, because I often use images on the web that were originally created for print. These images are usually CMYK, or 1bit (black and white). I immediately convert them to RGB, and change the DPI to 72. Creating images for the web is completely different from creating images for print. Read more..

MAC vs PCs 2

Macintosh versus PC?

My first post bout MAC vs PC was like 3 months ago. I mentioned there that I’ll buy a Mac as soon as i can save money. True enough, I now own an ibook G4 12 inch. I bought it a week ago and I am very satisfied with its performance. However, my first hour with MAC was so confusing.

Jem, who assisted me in the store showed the ibook and told me she will leave in a moment so I can check on the MAC. At one point I was glad because I can indeed scrutinize the laptop. On the other hand I was left with a big a Question mark because I had never used a MAc before. And so, to avoid embarrassment from all buyers who where inside the  store that time, I started to slide my finger on the trackpad and tried to click on anything as if I am a MAC user. I first clicked on the single icon I saw on the desktop, it was named MACINTOSH HD. The filed opened and I saw on my left scrollbar, DEVICES, SHARED, PLACES, and SHARED FOR.I was looking for things like, MY DOCUMENTS, MY COMPUTER, RECYCLE BIN, etc. And so, I was left with a Big “?” again. “What now?” I thought. As a customer came close to see what I was doing, I immediately clicked on the MACINTOSH HD icon under DEVICES so that the customer will not noticed I was confused hehe. And so a display of several applications showed up. There was the Ichat, Imovie,  quick time player, itunes, etc. I even noticed a file with a name SAFARI and thought it was lists of animals 🙂 Anyway, I didn’t bother to click on that and went on by clicking the itunes since that was by far the most known to me that time. I played few music files and continued to explore the MAC. Few minutes later, Jem appeared and asked if I was doing fine. I slowly whispered her,  “actually jem, its my first time to use mac.” She then taught me few basics and demo. Somehow, it helped me grasp more pictures about MAC. 

After that short lesson, I told her I’ll buy the laptop. Even if back on my mind, I still have lots and lots and even tons of questions about how to use the MAC, I paid the unit and went home. Another 3 hrs travel home and I chanced to  read the manual that goes with the unit. It was like I bought a new cellphone and got to know my CP by reading its manual. And so, i arrived home and started to open my MAC. I tried to performed few things I read from the manual and began to acquaint myself with my new buddy. I then went on by clicking every icon I saw, even the SAFARI. Thats when I knew that SAFARI was a web browser application not an encyclopedia or a trip to a zoo program 🙂  I then found out that MACINTOSH HD icon was like the MY COMPUTER of PC. MY DOCUMENTS was equated with the DOCUMENTS in MAC. I was even  amazed by an application DASHBOARD since I can group programs/applications I want in just one click. I discovered more and more things and began to realize that MAC wasn’t difficult to learn at all. Its just maybe because many people here know PCs than mac. Anyway, first times are always more tasking.

A day after, i brought my Laptop at my office. I immediately tried to experiment how it will deal with viruses. Since the computer in our office was filled with so many viruses, I plugged my Flashdisk for a while so it will be infected and plugged it eventually on my MAc. Undoubtedly, files like “exp1orer”, “recyler”, “autoRun”, “smss.exe”, nyg1xz, etc showed up. I immediately dragged all of it  into the Trash bin and a pop-up menu asked  me if i still intend to continue since the files were all locked. I clicked Yes of course. And so, it were all in my Trash bin. however, as I tried to empty my Trash bin, the viruses cannot be deleted. Few instructions later revealed that I just need to press the option bar so it will be deleted. Without delay I press the option bar while deleting my trash. And so, I  was very  glad to hear a crashing sound as the files/viruses were totally removed/deleted.

I immediately spread this good new in our office because our office is currently plagued with viruses. In fact, an office mate can no longer boot his HP laptop because it was infected with a virus named “UST Scandal.exe” And so, few personnel went to  me and let there flashdisks cleaned by manually removing suspicious files.

Well, I am just one of the happiest persons because I somehow get rid of these very annoying viruses.

So, you guys out there, think twice before you buy another PC. If you buy a PC, you may avoid “firsttime confusions” in MAC but you will never get rid of the thousands of viruses which will eat your time, money, effort, and patience. Think twice! Consider a MAC.

MAC vs PC

I live in the Philippines, a country where market of PC is incomparable to MACintosh OS computers or MAC for short. To prove my point, I, in my whole life, have not seen a single Internet Cafe that uses MAC computers. However, PC users flood to almost every corner in our land. (Although I “heard” there are already installations that use MAC comps LATELY)

I don’t have YET a MAC computer. I may not be credible as of the moment to say MAC is better , but still I would highly recommend those who have plans to purchase laptop or desktops, choose MAC! Why? I have searched from the internet and discovered so many advantages in using MAC. But among all the advantages, the best thing I would like to have is its VIRUS free environment.

Virus has been a big hustle to me and for sure to all of you. It has also been the source of many disappointments to all my officemates more especially those who usually cram on deadlines. It also has eaten much of my time like the regular scanning, updating and sometimes reinstalling my system if viruses penetrated the brain of my computer. It is one of the major things I wished could have not existed. And that is reason why MAC smells good to me.

Just this morning, I attended a meeting and one of the presenter was not able to show his slides because he cannot see any document files in his flashdisk. After a scan, several viruses were detected and the anti-virus could not delete some of it. Thus, the meeting turned into a 30-minute waiting conference. Coincidentally, a member of the group has a MAC notebook. The disk was inserted in the USB port using the MAC and wholaaaa, there were 8 suspected viruses such as autorun, recycler, and so on. The viruses where deleted and the flashdisk again was slotted to the PC’s USB port. And amazingly, his document files showed up.

I mentioned that I don’t own a MAC yet, but as soon as I will have enough savings to buy one, I surely will never regret a VIRUS-FREE environment. I just wont get rid of the numerous viruses but also, I can save time and money from regular scans, updates and purchase of Anti-viruses, which are most of the time, overran by newer viruses.

So, MAC versus PC? MAC WINS!
