Power line networking basically turns a building's existing electrical wiring -- the wires that carry electricity to different outlets in the house -- into network cables, meaning they also carry data signals for a computer network. And this means virtually all households, in the U.S at least, are "wired for" power line networking. It doesn't replace a regular network, so you'll still need a router, but it's a good way to extend … Read more
If you're looking for a fun, engaging game to while away the hours, look no further than this neat, connect-the-dots app. Flow Line Branch presents a really challenging spin on the Flow format that's gaining steam in mobile gaming. It's not only fun, but your mind will definitely get a workout solving these tough puzzles.
Unlike other flow games, Flow Line Branch requires you to connect multiple lines to the same multicolored circles. Since you don't have nearly as much room as you'll need to do it easily, you'll need plenty or trial and … Read more
While the need to locate a specific line in a text file may not be a very useful feature in regular prose text, for managing structured code such as scripts and XML files that are common in OS X, being able to identify a specific line or two may be quite useful.
If you have attempted shell scripting in OS X, you may find that when your scripts run into errors you will be given a brief description of the problem that includes the line where the problem occurred. While the use of BBEdit, TextWrangler, and other powerful text editors … Read more
You have plenty of choices when it comes to tools for editing the EXIF metadata contained in your digital images and other files, everything from dead-simple freeware to pro-level applications running into three figures. ExifTool definitely belongs among the freeware, but whether it's a simple tool depends on how you feel about the Windows command line. If you have no idea what that is, ExifTool is not for you; much friendlier metadata tools aren't scarce. But if you can handle Perl or have no problem with the Command Prompt (or typing characters and spaces) then ExifTool offers a … Read more
Everything on a Mac looks so polished on the outside that it may become unclear how to fine-tune settings under the hood of its graphical interface. Cocktail for Mac allows you to access an impressive number of useful tweaks and enhancements without entering a single line of code.
Cocktail for Mac can manually trigger maintenance scripts, optimize inactive RAM manually or periodically, toggle Spotlight indexing for chosen drives, force special startup modes, and access a lot of the hidden Finder and core app settings, to name just a few options. By "hidden," we mean those settings that are … Read more
Imagine yourself as England's Frank Lambard playing against Germany in a preliminary match during the 2010 FIFA World Cup. After kicking a solid game-tying shot, you watch the ball oddly bounce downward off the top rail, then in and out of the goal. Even though video footage proves otherwise, the referees disallow the score and Germany eventually goes on to win the game.
Fortunately, such epic miscalls seem less likely to happen during the 2014 World Cup and beyond, as the soccer-regulating organization FIFA plans to utilize a highly accurate sensor system capable of detecting successful shots and ensuring the referees should get the call right every time.… Read more
At a street price of around $50 for a kit of two units, the Actiontec 500 Mbps Powerline Network Adapter Kit is a bargain. And that's not the only good thing about it.
The kit, retail model number PWR511K01, comes with two identical adapters, currently the smallest of their type, that offered very good performance in my testing.
The only real complaint I have is that these adapters don't support Gigabit Ethernet, hence offering the limited data rate of the regular Ethernet standard at most. However, the affordable price and the supercompact design still make the kit an … Read more
As with many other Unix-like systems that have a BSD interface, OS X includes a fully Unix-compliant terminal that can be accessed with a Unix shell in the included Terminal utility. This feature allows for a relatively powerful way to access and modify system settings to customize and troubleshoot the system.
As with the rest of the system, this command-line interface is by default limited by standard permissions restrictions so only administrators may access system files and only users may access their own files. To get around this, the sudo command is commonly invoked to execute commands as another user, … Read more
