Untethered iOS 6.1 evasi0n jailbreak arrives for iPhone, iPad, and iPod touch devices

An untethered jailbreak means users can install it on their device once and for all. They don’t have to worry about a dead battery or restart requiring them to hook up to a computer and jailbreak the device again.

If you ever need to do this this article would be a good place to start your journey.

No, free Wi-Fi isn’t coming to every US city

We’ve written about White Spaces on numerous occasions. The FCC gave its thumbs up in 2008. We wrote about test networks in 2010, and by December 2011 the FCC had approved the first White Spaces broadband device.

LOL.  I read the free Wifi story in the Chicago Tribune and even on slashdot.

WebRTC

WebRTC is a free, open project that enables web browsers with Real-Time Communications (RTC) capabilities via simple Javascript APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high quality, RTC applications to be developed in the browser via simple Javascript APIs and HTML5.

The WebRTC initiative is a project supported by Google, Mozilla and Opera. This page is maintained by the Google Chrome team.

And the latest current events surrounding WebRTC is this:

From: Hello Firefox, this is Chrome calling!

For the first time, Chrome and Firefox can “talk” to each other via WebRTC. WebRTC is a new set of technologies that brings clear crisp voice, sharp high-definition (HD) video and low-delay communication to the web browser.

SSD onslaught: Hard drives poised for double-digit revenue drop

According to a market report from research firm IHS iSuppli, HDD revenue is set to drop to about $32.7 billion this year, down 11.8% from $37.1 billion last year.

Much of this has to do with newer devices sold being those that do not use standard hard drives like smartphones and tablets.  Perhaps we’re seeing the start of another computing technology headed for the museum.

Magnetic logic makes for mutable chips

A research group based at the Korea Institute of Science and Technology (KIST) in Seoul, South Korea, has developed a circuit that may get around these problems. The device, described in a paper published on Nature’s website on 30 January, uses magnetism to control the flow of electrons across a minuscule bridge of the semiconducting material indium antimonide (S. Joo et al. Nature http://dx.doi.org/10.1038/nature11817; 2013). It is “a new and interesting twist on how to implement a logic gate”, says Gian Salis, a physicist at IBM’s Zurich Research Laboratory in Switzerland.

This seems like a revolutionary discovery if it can be manufactured relatively easily.  And then there’s this:

But Johnson notes that magnetism is already catching on in circuit design: some advanced devices are beginning to use a magnetic version of random access memory, a type of memory that has historically been built only with conventional transistors. “I think a shift is already under way,” he says.

Free SIP/VoIP client for Android

For Google™ Voice users, Sipdroid can now create a new, free PBXes account that is automatically linked to an existing Google™ Voice account. The new feature requires Android 2.0, or above, and Google’s app connected to your Voice account.

Just found this site and sipdroid looks like an interesting VOIP solution for a tablet wifi.  Will download to see how it works.

The Forgotten Secrets Of The Enterprise Giants: Virality, Word Of Mouth, And Other Radical Experiments

Did you know that Salesforce initially launched with an activity-based pricing model, where the first two seats were perpetually free? It was designed to get critical mass in a company to soften it up for an inside sales call — and it worked great. This was their sales model up to about $17 million in sales, until the dot-com crash wiped out fundraising opportunities right at a moment when they had high customer churn combined with a major spend on inside sales, creating a cashflow nightmare.

If there’s one lesson that the old school continuously fails to teach, it is stop listening to the so-called (and self-styled) experts. Do your own research, talk to the original sources, and just go out and build your crazy thing.

Brogrammer Killed The Requirements Engineering Star

Writing functional and technical specifications – even for simple programs – is a vital skill, forcing programmers to think through what it is they want to do before they start doing it. They’re also invaluable for the generation (or two) of programmers who may need to modify or update your code after you’ve moved on. Trying to make even simple changes to a program without introducing new bugs requires a detailed understanding of what the program or function is supposed to do and how it was written. Without proper documentation, that job becomes much, much harder, Lamport says.

Interesting read as well as the two featured comments.

Why We Should Build Software Like We Build Houses

Architects draw detailed plans before a brick is laid or a nail is hammered. Programmers and software engineers don’t. Can this be why houses seldom collapse and programs often crash?

via Why We Should Build Software Like We Build Houses | Wired Opinion | Wired.com.

This analogy made me laugh because software doesn’t have to fight gravity or -20F temperatures or whatever else planet Earth has in store for a physical structure.  The gist of this article however seems to be that every software project should start with and needs a solid foundation of requirements.  Shout out to system engineering!

Update:  Here’s an interesting comment from slashdot and a shout out to awk.

If builders built houses the way programmers built programs, the first woodpecker to come along would destroy civilization.

Trivia: Gerald Weinberg is the “w” in awk. Sadly, things haven’t changed much since back when.
