Problem: Article: The shell can be opened by using the following key combination: Control + ALT + F1. You can also open a Terminal that acts as a shell from your System Tools folder. All commands listed below can be entered at the command line in the Linux shell or Terminal. The following commands require root privileges, so you should be logging in using su (or sudo). Type in your login and password to log as root.  Users of Debian Linux should type in the following command: “apt-get install unrar” or “apt-get install unrar-free”. If you are using Fedora Core Linux, type in the following command: “yum install unrar”. Arch Linux users should install from extra repository using "pacman -S unrar". Users of OpenBSD type in this command: “pkg_add –v –r unrar”. Suse10 users can enter “yast2 –i unrar”. Suse11 users can enter “zipper install unrar”. Type “cd /tmp”. Type “wget http://www.rarlab.com/rar/rarlinux-3.9.1.tar.gz ”. Unrar the file with the following command: “tar -zxvf rarlinux-3.9.1.tar.gz”. Enter “cd rar”. Type “./unrar”. “cp rar unrar /usr/local/bin”. The unrar command is now available for use in your Linux installation.
Summary: Make sure that your computer is connected to the Internet. Open up the Linux shell if you are currently in the Linux GUI. Use the right command to download unrar into your Linux installation. Download the binary package directly from rarlab if the above commands don’t work. Locate the rar and unrar commands in the rar directory. Copy the rar and unrar to the /usr/local/bin directory with the following command:

Problem: Article: PowerPoint presentations are useful to provide an overview, a general description of a given topic.  Your presentation should not be encyclopedic.  Don’t go overboard including every little detail, citation, or factoid which may inform the conversation on the issue you’re presenting.  Too much information will burn your audience out and you’ll be left with a bunch of people more interested in lunch than in what you have to say. Keep the presentation about you, not the slideshow.  The slides are there to support what you have to say.  They should be just one part of your presentation, not the whole thing. PowerPoint presentations are at their most effective and powerful when they adopt a clean, minimalistic style.  For instance, if you have one slide whose heading is “Habitats,” with three bullet points beneath reading “Forest,” “Desert,” and “Ocean” with a description of each habitat following, you would do well to instead allocate three separate slides to the three different habitats, and include a summary and image of each on the appropriate slide. Your PowerPoint slideshow should always be designed to reinforce your verbal explanations with visual images.  Sometimes it works to put words on a screen, but generally, your text should be limited.  Do you need the graphics as a starting point from which you will explain results, trends, predictions or specific outcomes?  Are you using visuals merely to keep your audience engaged, to provide humor, and/or to accommodate diverse learning styles?  These and other relevant questions should guide your decision-making process when settling on the right number of slides for your presentation. Go through your entire presentation and ask yourself if you really need a given slide.  If the answer is no, or if you find you can deliver the info verbally instead, eliminate it.
Summary: Provide the right amount of information. Break complex slides down into several simple slides. Include audiovisual support only as needed.

Problem: Article: Most limousine companies offer six-, eight-, and ten-passenger vehicles. There are also larger options such as Hummer vehicles, “extra stretch” limos or limo busses. If you’re going on a date and there will only be two of you, you may want to opt for a sedan.   A standard four- to six-passenger limo runs about $60 to $65 an hour, whereas a stretch limo for six to eight people is $150 to $175 per hour.  Party bus limos for fifteen to twenty passengers cost $125 to $175 per hour. A sixteen-passenger limousine rental is about $97-$107 per hour. A twenty-five-passenger limo bus costs about $225-$300 an hour. You’ll be more comfortable with extra room rather than filling the limo to its maximum seating capacity. People are different sizes, so as a rule of thumb you’re better off getting a limo with seating capacity for two more spots than you intend to fill.  For example, if you have four people in your party, opt for a six-passenger limo. Try to book a vehicle that has room for at least one to two last minute extra people than are in your party, just in case. There are various extras you may want included. For example, some limos have a TV, VCR or DVD player, a sound system, car phone, sunroof or Jacuzzi. Verify that the limo will have fully working seatbelts, as well as air conditioning or heat upon request. Ask if the color, size and make/model of the vehicle are guaranteed. It’s important to view the exact vehicle you’ll be riding in beforehand to make sure you approve of it. If the company refuses to do this, look for a different provider.  Ask if the vehicle has had regular inspections and is certified as both safe and mechanically sound.  For instance, the vehicles should be DOT inspected and approved.  Make a note of the license plate of the vehicle you are hiring to ensure that you get the correct vehicle on the day of the event.
Summary: Determine how many people will be riding in the limo. Make sure you’ll have enough room. Review features you may want included. Decide on the vehicle type you are interested in.

Problem: Article: This is so that the top layer seams are offset with the bottom layer. You want each layer of blocks to be different from the one below it. For example, if the wall has straight edges on the ends, the next layer should start with a block that has been cut in half.  Place the blocks onto the foundation before applying the adhesive. See how they look; ask yourself whether you need to make any significant cuts before gluing . Lay out one whole row before moving on to the next step. If you're working with blocks that have flanged tongues, simply line up the female groove of the top block with the male groove of the bottom block. Next, fit the top block overhead. Press down to make sure that each layer is secured tightly against the layer beneath it. Continue until retaining wall is its preferred height. If your wall is over 3 ft (.91 m) in height, you should offset each new row slightly back from the row below it, like very shallow stair steps. This will make your wall more stable and help create a better hold with the soil once you backfill. Look for a perforated pipe and lay it down the length of the retaining wall, covering it up with breathable backfill. Make sure water can drain out of your pipe, either at the ends or through an outlet in the middle of the wall. Topper stones usually come in rectangular shapes, making them more difficult to install in curved retaining walls. If you need to cut topper stones to fit the curve in your retaining wall, follow this trick:  Lay stones #1 and #3 out in their pattern. Lay stone #2 on top of #1 and #3, drawing lines on #1 and #3 where stone #2 overlaps them. Cut stones #1 and #3 along those lines. Line up #1 and #3 into place, snugging #2 in between. Repeat, placing stone #4 on top of stones #3 and #5. Add plants, vines, or flowers as necessary. Your retaining wall is ready to be enjoyed.
Summary:
Start your second layer with a staggered pattern. Apply the recommended adhesive to the bottom blocks, once a layer has been provisionally laid out. Add drainage pipes to your retaining wall, if the wall is 2 feet (60 cm) or taller. Add topper stones, if desired. Place topsoil in the basin created by the retaining wall.
