Network protocol nerd. Especially 802.11, TCP/IP, and Apple technologies.

I hate downvoting, but I hate wrong or misleading information in Answers even more. I also don't like to "put words in people's mouths" by editing their Answers for correctness. So if I see an Answer with wrong or misleading information in it, I tend to downvote it and leave a comment explaining why, unless the Answer was so far off the mark or so riddled with errors that I didn't even know where to begin. If you edit your Answer to fix the problem(s), please let me know with an @Spiff comment! I will review the change, and if I agree that the errors have been resolved, I'll happily remove my downvote, and delete my critical comment. (Anyone can change their vote if the thing they voted on was edited after they voted.)

comment Is a longer Wi-Fi antenna better?
@DrMoishePippik Your comment is full of misconceptions. Omnidirectional antennas DO have gain over isotropic antennas. Isotropic is the "i" in "dBi". Simple dipoles ARE omnidirectional antennas. Well designed half-wave dipoles can have as much as 8 dBi gain.

comment Is a longer Wi-Fi antenna better?
@STTR He's asking about stick-shaped antennas with omnidirectional coverage patterns, not triangular directional antennas like log periodic.

What does this have to do with 802.1X authentication? You said it in your title but not your description.

comment Is it possible to have a file hidden in Windows, but visible in OS X?
This is not a complete answer, but it's always been possible to make CD-ROMs with a hybrid filesystem that presents as ISO9660 to Windows, and HFS+ to Macs. I imagine it would work fine even if the medium is a flash drive instead of an optical disk. en.wikipedia.org/wiki/Hybrid_disc

comment Router to router setup works fine with straight cable up to 2-3 meter it is not working for 45 meter why?
I'd add that people should beware that the kind of dumb tester pictured only tells you if you have the correct pinout. It can't tell if you got the twisted pair pairings right, and those pairings are critical for the noise cancellation that becomes critical at longer lengths. The pairings are 1&2, 3&6 (6, not 4), 4&5 (5, not 3), 7&8.

comment Terminal executes a seemingly arbitrary command when opening a new tab in Mac OS X 10.10
There are several settings in Terminal.app's preferences that let you specify what commands are run when you open a new window. Have you checked those?

comment How can I debug OSX memory card events
By the way, what do you mean by "I even installed the IOUSBFamily"? IOUSBFamily is a built-in part of OS X. Did you install some alternate version? Did you replace the built-in version with whatever other version you found? What exactly did you install?

comment How can I debug OSX memory card events
You tagged this question osx-lion. Is it really Lion-specific (Mac OS X v10.7.x, from 2011)? The exact OS X version you care about is important, because Apple tends to tweak their logging schemes with each year's major release, so the answer for Yosemite might not apply to Lion. Did Lion still have kernel.log? Did you check system.log?

comment Creating a Network Diagram with .pcap
I'm not sure why people are voting to close this as off-topic. I suppose it might find a better audience on NetworkEngineering.StackExchange.com or even ServerFault, but I think it's a fine question for SuperUser as well.
