It is absolutely imperative that you refill the gear oil in your car's rear differential with the correct type of fluid.  Refer to the owner's or service manual for your car in order to find the correct type of gear oil to purchase.  You can also ask the clerk at your local auto parts store to assist you in finding the right gear oil. Purchase gear oil that comes in a squeezable plastic bottle with a spout unless you have an oil pump to use. Open the container of rear differential gear oil and insert the end of the long spout into the open filler/service port.  Squeeze the bottle slowly to push the oil out of the bottle and into the differential until fluid begins to leak out of the hole.  Make sure to wipe up any fluid that leaks out of the open service port. If the differential takes an entire bottle of gear oil, you may want to have the differential looked at by a mechanic to address any possible leaks. Once the differential is full, reinsert the plug for the filler/service port and turn it clockwise (to the right) until it is tight.  Use the appropriate wrench to tighten it enough to ensure it won't vibrate loose as you drive.  Do not overtighten the plug, it needs only to be tight enough to be secure. Remove the jack stands and lower the vehicle back to the ground.

Summary: Purchase the correct type of gear oil. Insert the spout into the filler/service port. Replace the filler plug.


Diatomaceous earth (DE) comes in two forms. Most DE sold as a pest control treatment or labeled "food-grade" is safe for home use and not linked to serious health issues. Never use pool grade or industrial grade DE in your home, since these forms can (eventually) cause permanent respiratory problems.  All DE products are actually a mix of the "safe" and "unsafe" types. Food grade DE still has a small amount of "unsafe" DE, and is still dangerous if inhaled in large quantities. DE sold for pest control has to meet specific safety standards and list safe instructions on the label (at least in the US), so this is usually the best choice. Food grade DE may not have a detailed safety label, since it is not intended to be used in pure, dry form, but it is similar to pest-grade DE and the risk of harm is low with the precautions below. Since food-grade DE is meant to be stirred into food and eaten, some people assume it is completely safe. However, the concentrated, dry powder can seriously irritate the lungs, eyes, and skin. Review these safety precautions before you begin:  Always wear a dust mask at minimum, since inhalation is the main danger. A respirator mask is much better, especially if you plan to use DE many times.  Wear gloves, eye protection, long sleeves, and long trousers. Keep children and pets away from the carpet while the diatomaceous earth is there. Consider testing a small area first, following the instructions below. Assuming there are no negative reactions from you our your household members, repeat on the rest of the carpet. Professional pest controls use special dusters to put down a fine, even layer of dust, but these can be hard for consumers to find. You can use a feather duster, paint brush, or flour sifter instead. Spoon (don't pour) the DE onto the dusting tool slowly, to avoid a cloud of dust. Squeeze bottles or bellows are not recommended, since they cause too much drifting.

Summary: Use pest grade or food grade diatomaceous earth. Follow safety instructions. Choose a dusting tool.


Modern saints in Roman Catholicism are all Catholic themselves, so if you have not yet been baptized and confirmed into the church, get on that right away. If you have been living a life of sin so far, don't worry: many saints were sinners who underwent radical, life-changes when they joined the church. It's tricky, but you can still make sainthood if you have a miraculous conversion and then turn away from your debasements to take up a life of virtue. There are lots of different ways to do this, from comforting the sick and dying to spreading the word of God, from fighting against poverty and oppression to devoting your life to scholarly study. Whatever you do, it has to be virtuous, selfless and memorable. Don't try explicitly to become a saint—just focus on being the best, most compassionate Christian you can be. Be humble and work to serve God and make a positive difference in the lives of others.  Joining the church as a priest or nun is a good start, but not required. The Vatican works hard to identify laypeople who are candidates for sainthood. Think big! Some saints are honored for extraordinary service to a small group of people or local community, but your exemplary life is more likely to be recognized if you have a bigger, more globally noticeable impact. Miracles are extraordinary events not normally attainable through human works, and thus attributed to the intervention of a divine and supernatural power. Unexplainable healing of the incurably sick, wounded or dying is a classic, as is interceding to miraculously stop or rescue people from an impending disaster. Really, however, a miracle can be any inexplicable but benevolent phenomenon you can conjure up. Just remember, you aren't really performing these miracles: God is performing them through you. You don't technically have to perform these miracles while alive—you could intercede from heaven to make your miracles happen instead. However it isn't as guaranteed that you will be recognized for the miracles you perform after your death, so it doesn't hurt to get this requirement out of the way as soon as possible. No getting around this one: sainthood is a posthumous title. In fact, the canonization process only begins minimum of five years after the subject's death. If possible, try to be martyred for your faith. This happens less and less these days, but being killed because you refused to renounce your (Catholic) religious beliefs is sure to get you and your sainthood case noticed.

Summary: Become Catholic. Live an exemplary and pious life. Perform at least two miracles. Die.


Paint is a feeble program in terms of photo editing and retouching, but it's not without its uses. Right-click and choose to open your photo in Paint, and you can easily rotate it, resize it, or crop parts of the image out. You can crop and zoom to “blow up” a specific part of the picture too, although image quality will suffer. Paint can save edited files in various popular formats, including PNG and JPEG.  Paint is also useful for adding text to an image. Be sure to select the transparent text box option so that the text box doesn't appear as an ugly white ribbon blocking out the image underneath. Most of Paint's other options are fine for doodling, but useless for photo editing. If you've lost your copy of Paint, download the superior Paint.NET program instead. It was started as a Microsoft project to replace Paint, and it has more features than the original. The link to download it is provided later in this article. The free version of Serif's elegant photo editing software may not have the features of a program like Photoshop, but it's a dream for gently editing photos. Red-eye reduction, color correction, and several basic filters and effects make this an ideal program for the person who wants to make a family reunion photo look a bit better. If your photos don't require extensive touch-ups, but you suspect they might look better with a bit of basic filter and layer manipulation, PhotoFiltre is the program for you. The program features a large number of professional, easy-to-use transparency and contour effects that can change the look and feel of nearly any photo. It's also very streamlined, and takes up hardly any space on your hard drive.  PhotoFiltre is free for private use, but if you plan to use it commercially (creating advertisements, for example), you'll need to pay for a license. The licensed version is somewhat more powerful than the free version. You can safely download PhotoFiltre 7 from the PhotoFiltre website.
Summary: Use Microsoft Paint for basic adjustments. Grab Serif Photo Plus. Use PhotoFiltre to add filters and effects with ease.
