Golang is GO GO GO!

@ipyandy Tweet

You will have to be a programmer if you’re going to be a network engineer in the future, they say. I don’t agree, but it surely helps you do your job. But what language should you learn? Perl? (no) Python? (maybe) Ruby? (perhaps) Every time I say something about learning Python, a little voice on Twitter says Or Go!. Go? Go. And so, sucker that I am, I gave it a go (pun intended). TLDR: I think you should, too.

The Go Programming Language

The name Go feels like it should be a terrible word to search for on the Internet because it’s so short, but searches actually work remarkably well if you use Google Search. Compare the results of a search for “go if then else” from Bing and Google below; I’ll let you guess which is which:

Maybe Google has learned from my search history. So, what’s important to know? Go is:

  • Open source. The source code is readily available and can sometimes be helpful to figure out what’s going on.
  • Free, obviously
  • Pretty fast
  • Multi-platform (Linux, OS X, Windows for starters)
  • A compiled language
  • Strongly typed
  • Capable of Continue reading

Google lends Apple support over FBI encryption demands

Google CEO Sundar Pichai has lent support to Apple in the debate over encrypted iPhones—sort of.In a series of Twitter posts, Pichai praised Apple CEO Tim Cook for writing an “important” letter that speaks out against the FBI’s decryption demands. “Forcing companies to enable hacking could compromise users’ privacy,” Pichai wrote.While Pichai noted that Google provides data access to law enforcement when legally required, that’s different from making tech companies enable hacking of customers’ devices and data. “Could be a troubling precedent,” Pichai added.To read this article in full or to leave a comment, please click here

Man rescued by Disney cruise ship charged with hacking Boston Children’s Hospital

Disney might bring to mind a warm and fuzzy happy ending, but such was not the case for a 31-year-old man who sent out a distress call from his boat, was rescued by a Disney cruise ship near Cuba, and then arrested in Miami for his alleged involvement with an Anonymous cyberattack against Boston Children’s Hospital.After Martin Gottesfeld and his wife pulled a ghost and vanished, relatives and his employer reported them missing. The FBI had been investigating him since October 2014, when the agency searched his house for evidence linking him to a cyberattack on the hospital. According to the DOJ press release, a few days ago, FBI “counterparts in the Bahamas” contacted Boston’s FBI to report that Gottesfeld was not a registered guest on the Disney cruise ship which rescued him at sea.To read this article in full or to leave a comment, please click here

Popular home security system SimpliSafe can be easily disabled by burglars

It's not unusual to hear of vulnerabilities in smart-home security systems these days, as security researchers turn their attention to the Internet of Things. It's worrying, though, when a modern security system turns out to be vulnerable to a so-called replay attack, the kind of thing that worked against garage door openers back in the 1990s.The latest example is SimpliSafe, a wireless alarm system that's marketed as cheaper and easier to install than traditional wired home security systems. Its manufacturer claims that the system is used in over 200,000 homes in the U.S.According to Andrew Zonenberg, a researcher with security consultancy firm IOActive, attackers can easily disable SimpliSafe alarms from up to 30 meters away, using a device that costs around $250 to create a replay attack.To read this article in full or to leave a comment, please click here

Latest tests show all four major wireless carriers are strong

Despite claims by the four biggest U.S. wireless carriers that each one has the best nationwide network, the latest performance data gathered by testing firm RootMetrics shows that are all good and getting better."This a great time for consumers. Network providers are really trying hard so that consumers ultimately benefit. You're not going to go wrong with any one of them," said Julie Dey, vice president of RootMetrics, in an interview.The competition between all four has been tight for years, but came into special focus in the last two months as Verizon, then T-Mobile and Sprint started running separate national ads that show tiny colorful balls running down a track with a narrator asserting each carrier's network superiority.To read this article in full or to leave a comment, please click here

White House: FBI is not asking Apple for a ‘backdoor’ to the iPhone

The White House said  it is not the aim of the government to compromise the security of Apple's iPhone, as it only wants the company to help in the case of one phone that was used by a terrorist in the San Bernardino, California attack on Dec. 2.Google, Mozilla and some other tech organizations and civil rights groups have meanwhile supported Apple's stand.An order by a judge in California on Tuesday triggered off a furious response from Apple CEO Tim Cook, who said the government wanted the company to provide a backdoor to its phones. Magistrate Judge Sheri Pym of the U.S. District Court for the Central District of California ordered Apple to provide assistance, including by providing signed software if required, to help the FBI try different passcodes on a locked iPhone 5c running iOS 9, without triggering off the auto-erasure feature in the phone after 10 failed attempts.To read this article in full or to leave a comment, please click here
