CD Cleaning Solution – Making Your Own

I see the kids were eating ice cream sandwiches while they dug through the DVD collection again. With kids in the house, it’s inevitable that whenever I want to listen to a CD or watch a DVD, I have to clean the discs before they will play. Luckily, I spent several years working in a CD manufacturing support group and learned the easiest way to clean discs and get them working again. Here, as simple as it may be, is my favorite solution for cleaning discs.

- Mix a large amount of water with a few drops of dishwashing soap.

That’s it. No expensive commercial cleaning solutions and no plastic washing devices for my discs. I know it doesn’t sound complicated enough or mysterious enough, but it works. This solution works most of the time if you:

- Use a soft cloth and wipe the solution on the disc starting from the inside hub and wiping to the outside edge of the disc. Never rub hard or in a circular motion. Don’t rub around the disc because you might scratch the disc creating an un-repairable problem.

- Dry the disc with a soft dry cloth. Again, wipe the disc from the inside to the outside. Straight out. Don’t go around the disc at all because you might create scratches that are parallel with the tracks.

Why does this solution work most of the time? On most CDs, and especially rented DVDs, playability problems are caused by fingerprints. Fingerprints are oil-based and the dishwasher detergent is designed to cut through and remove oil. If this method doesn’t work, you might have a disc with sever scratch or even a scratch on the label side of the disc. Scratched discs can sometimes be repaired with CD scratch removal solutions or CD repair services.

Dishwasher soap and water won’t fix scratches but will make many discs playable.

Microsoft Certification: Farewell To The MCSE

Microsoft is in the middle of a major push to overhaul its certification program. Last year, they announced the new Microsoft Certified Architect (MCA) certification, which is not a written exam but rather a practical exam that will be graded by a board of examiners. Just applying for the certification will require 10 years' experience in IT as well as three years of practical experience as a network architect.

For those of us not quite ready for that, Microsoft has announced that it's also going to revise other certifications. The MCSE that we've all come to know and love is going to be a thing of the past. In its place will be a series of specialization exams and IP Professional certification tracks.

If you're currently an MCSE or working it, don't worry, you have plenty of time to adapt to the new tracks. Microsoft's official word is that the new certification structure will be implemented when the next Windows server/client version is released. For those holding MCDBAs, your current certification will remain valid and you'll have a chance to upgrade to the new certification with SQL Server 2005.

Those of us who have been on the certification track for a while remember the outcry when Microsoft planned to phase out the much-maligned NT 4.0 certification in the move to Windows 2000. There was quite an outcry from many certified individuals who felt MS was being unreasonable in their timetable and planned lack of support for the 4.0 certification. Whether you agree with Microsoft's planned changes, I urge you to visit Microsoft's certification site regularly to keep up with these changes.

Whether you choose to pursue any of these new tracks is your decision, but you owe it to yourself and your career to know about the new tracks. Change is inevitable in IT and the IT certification world, and you must be aware of these changes!
