Decompress with The Unarchiver
When I was asked to review The Unarchiver 2.7, a free decompression utility from Dag Ågren/WAHa, I thought "Who needs this program, when Mac OS X opens most common archive formats?" I quickly found out that thousands of people rely on The Unarchiver to do tasks that lie beyond the scope of built-in Archive Utility.app found in OS X. First I spoke to a loyal user, Barry Porter, an Apple Consultants Network member from Delray Beach, Fla. He said, "I use it everyday. It's great. I haven't found an archive it can't open. I use it because the built-in program is very limited in what it can create and open. You never need to open the program, it just works in the background unarchiving stuff." That's a glowing recommendation, so I put The Unarchiver to my own test. Back in the old days, it was common practice to archive files by compressing them so that they fit on a floppy disk or CD. If you happen to have saved those files onto a hard drive socked away for safekeeping, today you are hard-pressed to open those files. The Unarchiver can decompress many file types, so rejoice, because you can actually open DiskDoubler, Compact Pro and PackIt files now. I dug up some seriously old files to test The Unarchiver. I found some .sit files from 1994 and The Unarchiver opened them. Oh joy! Anyone need an Macintosh FTP list from 1995? (Curiously though, my search for files created before 1999 found over 1000 files created in 1969. I'm pretty sure that's not right! Must be a backup from a crashed drive... but I digress...) If you use more current formats and various download sites, you may encounter RAR or Tar files. No problem for The Unarchiver there either. If you find bugs or have a problem, Dag Ågren maintains an old-school support board on which you can ask questions. Also included is support for over 29 languages and DOS and Windows formats. To install, you only need to download it from the App Store. The program runs in the background. When you double-click on the application, all you see is the Preferences window. The only time you have to interact with the program is to give it permission to write to a folder, if you want to extract an archive into the same folder in which it lives. If you're curious and want to know exactly how many different archive formats exist, first look at The Unarchiver Supported formats page. Second, take a gander at Wikipedia's "List of archive formats." This handy page explains all of the file extensions used on various platforms for archived and compressed formats. In short, if you need to open archives of any flavor, you can't go wrong installing The Unarchiver. If you like it, you can donate to help Dag Ågren's development efforts for other programs too. Requirements: OS X 10.6.0 or later
TUAW's Daily Mac App: TinyExpander
Every Mac comes with a built-in file compression utility, but its decompression support is limited. We've featured a perennial favorite, the Unarchiver before on the Daily Mac App, but today we'll take a look at a new kid on the Mac App Store block, TinyExpander. Just like the Unarchiver, TinyExpander is ready to expand whatever archive you throw at it. It'll handle over 25 different formats, with the highlights being Zip, 7z, RAR, TAR and XAR. TinyExpander is also able to extract encrypted archives, so it's pretty safe to say that it'll get the job done for almost any archive you're likely to have on a day-to-day basis, save for the really obscure formats. There aren't many preferences to change in TinyExpander (as you can see above), but you can set archives to expand to a custom folder, should you want everything extracted to the same place. You can also change whether it'll trash the archive or not when it's finished extraction, and also whether it'll show you the results in a new Finder window. If you expand an archive to a folder that already exists, TinyExpander will give you the option to overwrite it or cancel your action, which should help make sure you don't accidentally overwrite something important. TinyExpander is a great little utility that gets the job done without a fuss. If you're not enamoured with the Unarchiver, then the free TinyExpander is a worthy replacement.
NASA's PILOT project could autonomously extract oxygen from lunar soil
We've got means to extract oxygen from water, a portable bar, and even ways to deprive entire server farms of the sustenance, but a new project being tackled by Lockheed Martin is hoping to create O2 on the moon. A critical part of NASA's PILOT (Precursor In-situ Lunar Oxygen Testbed) initiative, this digger bot will work hand-in-hand with a "processing plant that will add hydrogen to moon soil, heat it to 1,652-degrees Fahrenheit, condense the steam, and finally extract the oxygen." Additionally, the blue LIDAR (Light Detection And Ranging) box atop the three-foot-long machine can assist it in locating "oxygen-rich lunar soil and autonomously carry it to a processing plant." The overriding goal is to use the newly extracted O2 for air, or moreover, to combine it with hydrogen and produce water for the four astronauts that the lunar base could support. Unfortunately, there's no timetable as to when we'll actually see the PILOT roll into action, but we're most interested in porting this bad boy over to Mars along with half the traffic in LA.[Via The Raw Feed]
Better Together at Amazon: Marmite yeast extract and .Mac?
Amazon must be testing some new accessory recommendation algorithms, as they have really branched out on this one: Reg Hardware in the UK has a story about Amazon UK's engine recommending Marmite, a popular sandwich-topping yeast extract in England, with a .Mac subscription. While I don't recommend spreading any Marmite on your .Mac anytime soon, I can see a connection between these two (im)perfect strangers via a former Marmite ad campaign slogan: "you'll love it or hate it." Nutrition facts aside, that seems to describe .Mac in a nutshell these days.No word on how soon this dynamic combo is shipping, nor how long this offer will last; "act now!"
