Submission + - DIY 4G Antenna Design for the Holidays?

eldavojohn writes: This holiday season I will return to the land of my childhood. It is flat and desolate with the nearest major city being a three hour car drive away. Although being able to hear the blood pulse through your ears and enjoying the full milky way is nice, I have finally convinced my parents to get "the internet." It's basically a Verizon Jetpack that receives 4G connected to a router. My mom says it works great but she has complained of it cutting in and out. I know where the tower is, this land is so flat and so devoid of light pollution that the tower and all windmills are supernovas on the horizon at night. Usually I use my rooted Galaxy Nexus to read Slashdot, reply to work e-mails, etc. I would like to build an antenna for her 4G device so they can finally enjoy information the way I have. I have access to tons of scrap copper, wood, steel, etc and could probably hit a scrap yard if something else were needed. As a kid, I would build various quad antennas in an attempt to get better radio and TV reception (is the new digital television antenna design any different?) but I have no experience with building 4G antennas. I assume the sizes and lengths would be much different? After shopping around any 4G antenna costs way too much money. So, Slashdot, do you have any resources, suggestions, books, ideas or otherwise about building something to connect to a Jetpack antenna port? I've got a Masters of Science but it's in Computer Science so if you do explain complicated circuits it helps to explain it like I'm five. I've used baluns before in antenna design but after pulling up unidirectional and reflector antenna designs, I realize I might be in a little over my head. Is there an industry standard book on building antennas for any spectrum?

Submission + - In Calculator Arms Race, Casio Fires Back: Color Touchscreen ClassPad ( 2

KermMartian writes: "In what seems to be an accelerating arms race for graphing calculator supremacy between Texas Instruments and Casio, the underdog Casio has fired a return salvo to the recently-announced TI-84 Plus C Silver Edition. The new ClassPad fx-CP400 has a massive color touchscreen and a Matlab-esque CAS. Though not accepted on the SAT/ACT, will such a powerful device gain a strong following among engineers and professionals?"

I did subscribe. At one time Stratfor had a "student" price structure and my University paid for it as it was relvant to my study. That is actually how I found these other news agencies. Stratfor offered (and I'm guessing still offers) what they call SITREPS which you could have either emailed batched, or as they came out. I had them delivered as they came out via email, and the vast majority, close to 90%, were credited/attributed to other news agencies like ITAR TASS etc etc etc. You're right, I was wrong in saying Stratfor was like HuffPo. Stratfor is more like an expensive Twitter (if you follow the right people on Twitter that is.)

Comment The Real Lulz (Score 3, Interesting) 89

The real lulz come from the fact that people take Stratfor seriously, and continue to use their overblown moniker of "private intelligence firm". They were/are a news aggregating group that sold stale news articles from REAL news organizations like ITAR TASS and Xinhua. And since most American corporate executives never heard of ITAR TASS, Xinhua, ABN, etc. etc., they were able to pawn it off as their own work. Not only did they sell old news, but they charged a huge price for it. They were essentially an expensive HuffPo with a wanna-be CIA spook edge for effect. Not surprising at all that they didn't encrypt their data, or provide any real security.

Comment GNU/Linux won because it works. (Score 5, Insightful) 480

The simple answer (and probably one of the more correct answers) is GNU/Linux won because it works. I love BSD, especially OpenBSD. I buy OpenBSD's CD's to contribute money to the project because I admire the hell out of it, but rarely do I try to run it. OpenSSH? Amazing. And that it came from such a relatively small group, just shows what a complete powerhouse the OpenBSD group is. However, when I got my OpenBSD CD's in the mail, I figured let's do the twice-a-year dance where I attempt to run OpenBSD. Results? On my primary workstation, OpenBSD's X doesn't agree with my video card. On my primary laptop, though I can get OpenBSD to install via CD, once installed, it doesn't recognize my DVD drive, and on my EEE machine, it doesn't recognize my wireless. Now, let's look at one of my favorite GNU/Linux distros, Trisquel. Which uses the linux-libre "deblobbed" kernel. It works, flawlessly, on my workstation and both laptops. Zero un-free drivers, blobs, or software. People can come up with as many theories on why GNU/Linux overshadowed BSD, but in my case, and in the case of many, GNU/Linux works better. BSD might have more elegant, bug free code, but for the vast majority of users, that doesn't matter, working features matter.

Comment Did anyone bother to read the author's own comment (Score 4, Informative) 487

"Note to all: Despite what you might read on Slashdot or other aggregators, this piece is about servers, not desktop FreeBSD use. Not sure how that got misconstrued, but I'm talking exclusively about server use. I haven't run *BSD on the desktop since 1998, hence my comment about Linux on the desktop and FreeBSD on the servers.
