Obfuscator

 

 

An obfuscator is a program designed to make it difficult to understand or reverse engineer source code. The obfuscator takes the clean human-readable source code the programmer has created and does a thorough job shuffling it around, changing simple variables to confusing ones, and otherwise making it difficult for another person to sit down and read the original clean copy (but all while still maintaining the functionality of the source code).

Obfuscators are particularly valuable for interpreted languages (such as JavaScript) where the end user can open and inspect the code; without obfuscation it would be trivially easy for someone to lift the code from any interpreted language source code.

Russell Roberts's curator insight, June 20, 2:02 AM

Thanks to reporter David Hall for this tasty little item!  The new Tektronix RSA 306 Spectrum Analyzer has got to be one of the best test instruments on the communications and Amateur Radio market today.  Some of its features include a frequency range between 9 kHz and 6.2 GHz; -160 dBm to +20 dBm dynamic range; and 40 MHz captured bandwidth.  I surely could use one of these precision test instruments.  The price has been pegged at around $3,490.  That's a bit expensive for my tastes, but, for a professional broadcast engineer, the owner of a radio repair business, or for a dedicated amateur radio contester, that's a small price to pay for Tektronix, made in the USA quality.  Excellent diagnostic tool.  Aloha de Russ (KH6JRM).

Thanks to reporter David Hall for this intriguing article.  Microsoft will release its Windows 10 Operating System on 29 July 2015.  I think I'll hold off awhile before switching from my Windows 7 OS.  There have been too many bugs and flaws in Microsoft programs lately, and I'm waiting to see how Windows 10 "flies" before I switch.  I tend to be cautious in such matters.  Aloha de Russ (KH6JRM).

Russell R. Roberts, Jr.'s curator insight, June 9, 7:27 PM

Thanks to reporter David Hall for showing what will be required to run Windows 10 on your PC or laptop.  Microsoft will debut the new OS on 29 July 2015.  Impressive as this new OS is, I'm going to wait until all of the "bugs" are worked out of the system before I dump my Windows 7 platform.  Microsoft has had too many glitches, errors, and bad coding over the past few months for me to install the program.  My task bar has the icon for Windows 10, but I'm going to bide my time until the OS has a bit more experience in the field. Your mileage may vary.  Aloha, Russ.

Good analysis of impending changes to the current, unreliable EAS system.  Thanks to reporter David Hall and the folks at http://www.radiomagonline.com.  When I left the commercial broadcasting field in 2011 (I retired), the EAS system was acceptable for local emergencies, but for the national scene, there was always some kind of technical glitch or computer problem that failed to include many broadcast outlets.  That situation is intolerable, considering the violent, dangerous age in which we are living.  Hopefully, the new standards will bring about needed changes in the antiquated EAS notification system.  Aloha de Russ (KH6JRM).

Russell Roberts's curator insight, May 16, 2:00 AM

Thanks to reporter David Hall for this exhaustive analysis from "Radio World" about the future of AM broadcasting in the United States.  This article will have significant importance for amateur radio operators who work as engineering consultants for AM radio stations.  The transition to an all digital AM broadcast band is coming, but no one knows when or what kind of system will be adopted for that service. Also on the agenda is what to do about FM translator use by AM stations overwhelmed by industrial noise and other interference issues.  The expanded AM broadcast band is another issue that will continue to heat up the medium wave debate.  All told, AM broadcast stations are reeling from a variety of interference and site issues beyond their control.  Aloha de Russ (KH6JRM).

Some sage advice from reporter David Hall and http://www.dictaylorblog.com.  When I left commercial broadcasting in September 2011, these positions were in demand--ironically these are the same positions outlined in this excellent article:

1.  Radio sales people, especially those with strong digital media backgrounds.

2.  Internet creators--something just getting started when I left broadcasting.  Many stations have a web presence and offer audio streaming through the Internet.  People are needed to present their stations to the digitally equipped and technologically aware listening public.

3.  RF Broadcast Engineers, especially those with a computer and digital technology background.

Positions not in demand anymore:

1.  General Managers.

2.  Promotion Directors.

3.  News reporters.  I was once the news director for my station chain on Hawaii Island. I branched out into RF engineering and sales early on and was able to work until I retired in 2011.  My Amateur Radio License also helped me establish a working relationship with the station's contract engineer.  I did a lot of work under his supervision.

 

So, for those aspiring to a broadcast career, ditch the announcing job and head to sales, content creation, and RF engineering.  I speak from experience.  And, by the way, I did some on-air work, too--mostly sports and remote broadcasts.  Aloha de Russ (KH6JRM)

Russell R. Roberts, Jr.'s curator insight, May 2, 11:48 PM

As our British cousins would say of David Hall's article, "Spot on, mate." As a 37-year veteran of commercial broadcast and college radio stations and a recently retired News Director of Pacific Radio Group, I can attest to the validity of the statements made in this well-crafted article.  The advice is clear and true:  Ditch the on-air announcer role and become a real force by entering radio sales, content creation, and RF Engineering.  I've worked in all three areas and had a wonderful, occasionally challenging career.  I also did on-air work when the situation demanded, such as sports, live remotes, newscasts, and filling in for on-air talent.  Good luck in your search for a meaningful job in broadcast media.  Aloha, Russ.

Despite plans to cut back the FCC's Enforcement staff, Travis LeBlanc isn't cutting any broadcaster, internet service provider, and the NAB any slack.  Le Blanc, who heads the FCC's Reduced Enforcement staff, has levied huge fines against Verizon, AT&T, T-Mobile, Century Link, and even the Marriott Hotel chain for exploiting customers and engaging in monopolistic behavior.  His recent $350,000 fine against a small Virginia television station for briefly showing a pornographic image has incurred the wrath of the NAB.  LeBlanc, who has the support of FCC Chairman Tom Wheeler and most of the public, says he will cite any media outlet under FCC supervision that breaks the rules of the Commission. We've been warned.  Aloha de Russ.

Thanks to reporter David Hall for this excellent, easy to understand tutorial on electrical noise and how to control it.  The article focuses on the four types of electrical noise we can expect to find in cables:

electromagnetic induction, galvanic, electrostatic coupling, and radio frequency interference (RFI).  Most of us in the Amateur Radio Community have run into some or all of these factors during our "careers" as ham operators.  The article also offers helpful suggestions on how to control noise--most of the solutions are cheap and easy to apply.
