Yesterday, while sitting in Starbucks writing a few notes with my iPhone and waiting for my coffee, I could see storm clouds darkening the sky far off in the distance. It's not an unusual sight and often is nothing to get too excited about. The news reports have all been about the high winds and wintry weather warnings due in our area. I’m referring to the news I actually pay any attention to. Politics are avoided. With Thanksgiving in a few days, it’s not a bad strategy to avoid unnecessary nonsense. Now a day later I can hear the rain on the roof of the shop start tapping along with the blowing wind as the temperature drops down to a more seasonable cool temperature range of misery. I had spent some time earlier this morning playing around with the Chromebook’s Linux beta support and
Sometimes a quiet day or two is just fine. No bad storms, no asteroid collision, no interesting tech news, just dull mediocrity. Yes, there's been some Linux Distro releases, and Apple product announcements, but nothing to lose any sleep over. There's no real reason to upgrade to a new laptop, no real need to update my iPhone, there's really nothing going on to get all worked up about, and that's not so bad. I can hold onto my wallet for a while, because I can't think of anything new recently announced that I really feel like I'm missing out on. That's good for me, but probably no so great for the industry. Too much excitement can sometimes cause real interesting news to get lost in a wave of noise. It's all perception. If you're actively looking and waiting for a particular hardware ...
Before man-built machines that could be used to manually calculate all the same mathematical problems we now regard as computation, we – humans were regarded as the “computers”, not the artificial machines. This explains the label “manually” calculated. Man built the machines. This has only been true for a relatively short period of time when compared to the timeline man has existed in the current evolutionary state. This technology goes back much farther than the existence of our most popular desktop pc, laptops, tablets, or smartphones. Major developments in the twentieth century progressed at a very rapid pace, not with the help of Extraterrestrial beings, but by some very brilliant humans. Maybe you could make a case for “math” from outer space in ancient history, and you’d be technic
The command sort is used to sort files line by line. Lines starting with a number go first. Lines that come next in order go alphabetical with uppercase letters appearing before lowercase ones. Use cat to create "testsort" for the example. ~/Test>cat testsort A line 1 a line 2 8 line 3 line 4 5 line 5 ~/Test>sort testsort 5 line 5 8 line 3 A line 1 a line 2 line 4 R sorts by using a random hash of keys ~/Test>sort -R testsorta line 25 line 5A line 18 line 3line 4 ~/Test>sort -R testsort5 line 5A line 1a line 2line 48 line 3
EGREP: The Command egrep is the same as running grep –E. egrep is used to search for a pattern using extended regular expressions. Terry@f:~/FinderDing>cat testsort A line 1 a line 2 8 line 3 line 4 5 line 5 Terry@f:~/FinderDing>egrep '^[a-zA-Z]' testsort A line 1 a line 2 line 4 *Show lines that start with a letter from alphabet Terry@f:~/FinderDing>cat html <!DOCTYPE html> <html> <body> <h1>My First Heading</h1> <p>My first paragraph.</p> </body> </html> Terry@f:~/FinderDing>egrep "My|first" html <h1>My First Heading</h1> <p>My first paragraph.</p> `*Find lines with pattern My first from html file FGREP: The command fgrep is the same as running grep –F. The Command searches for fixed character strings in a
