"Work" problems involve situations such as two people working together to paint a house. You are usually told how long each person takes to paint a similarly-sized house, and you are asked how long it will take the two of them to paint the house when they work together. Many of these problems are not terribly realistic (since when do two laser printers work together on printing one report?), but it's the technique that they want you to learn, not the applicability to "real life".

The method of solution for work problems is not obvious, so don't feel bad if you're totally lost at the moment. There is a "trick" to doing work problems: you have to think of the problem in terms of how much each person / machine / whatever does in a given unit of time

Luther did the right thing, standing on the Word at Worms. And we, too often, do all the wrong things in his name. We think that the glory of that story is that he stood his ground, that he was courageous, immovable, a rock. And so we go in search of the same opportunities. We boldly stand, and walk out of our churches because this possible inference of that potential trajectory of the other postulation in the pastor’s off-the-cuff remark might impinge on an important doctrine. We boldly defy the American empire, refusing to tell their census taker how many toilets are in our house. We boldly dishonor our parents, because we think them to be not quite as honorable as we are.

Tips and Tricks for Linux Mint after Installation

Linux Mint is the 4th most widely used operating systems in the world after Windows, Mac OS and Ubuntu, as claimed by the distribution.
Even though it's an Ubuntu-based system, Linux Mint features only one panel at the bottom which looks closer to the taskbar in the Windows system, and a well-organized start menu complete with a useful Search box. It also pre-installs some proprietary software, including the Adobe Flash plugin and necessary media codecs, by default so that you can view streaming media, such as YouTube videos in a browser, and play mp3, mp4 or most other media files with a player right away out of the box.

If you have the Linux Mint system which comes with the default Gnome desktop environment installed in your PC, you might find these tips and tricks useful for working with the system.

Why Pinoys need green lifestyle

By Annie P. Guerrero
Philippine Daily Inquirer

MANILA, Philippines--Growing up GROWING UP in the years after the war, I was taught to recycle things. Curtains morphed into tablecloths and aprons, clothes were handed down from sister to sister or from brother to brother, and oil containers became sprinklers. Of course, in those days we didn’t call what we were doing recycling. We thought we were simply and sensibly making the most of everything, since various resources were scarce after the war.

I remember that the garden was my favorite spot, and even then, I held close to my heart the principle of “waste not, want not.” We grew our own vegetables on the compost soil that we generated. There were no garbage collectors (basurero) back then, so we put our garbage to good use. Kitchen waste and yard waste (dried leaves and twigs), mixed with a little bird poop, made good fertilizer, and out of the rich compost soil came the vegetables that nourished us. The garden pots were used cans and the compost was mixed in used rubber tires. It was a natural cycle that we appreciated.
