How to find undervalued tech talent

Andrew Filev, CEO of Wrike, a company that offers task and project management tools, takes a unique approach to recruiting talent. While some companies might go after the most desired talent on the market, Filev prefers to hire the undervalued players, and foster their strengths to create a well-rounded team."'Island of Misfit Toys' is a nickname some of our team gave themselves one day at lunch when they were reflecting on how different their career backgrounds were prior to joining Wrike. These are people who landed at Wrike either without a lot of experience, or with an abundance of experience unrelated to their current positions -- often in jobs where they lacked challenge and growth. Since starting their careers here, they've become key players on our team and many are now in roles as team leaders or program managers, and are also big cultural assets in the company," says Filev.To read this article in full or to leave a comment, please click here

Five arrested for impersonating the IRS, listen to a recorded scam in progress

Five people have been arrested in Miami who are said to be responsible for scamming 1,500 people out of more than $2 million by impersonating IRS agents. Their scams centered on contacting individual taxpayers out of the blue and demanding payments under the threat of jail time. News of the arrests circulated Tuesday after the Associated Press reported on them. Sources in the Treasury Department said that the five individuals - all Cuban nationals - demanded money from their victims, threatening arrest if the payments were not wired immediately. In recent months, the scammers demanded payment via iTunes gift cards. Scams such as this, Deputy Inspector General Tim Camus told the Washington Post, have become the "largest and most pervasive" the IRS has faced over the last three decades. Some 6,400 victims have reported more than $36 million in losses, some paying up to $5,700 on average.To read this article in full or to leave a comment, please click here

Why I stay with Firefox

In a recent Network World column, guest author Susan Perschke discussed why she switched back to the Firefox browser, with its piddling low teens percentage of market share, from the dominant browser, Google Chrome.Perschke illustrated many good reasons to use Firefox, all of them legitimate and valid, but I have two good reasons of my own. Firefox has two feature Chrome just doesn't have.First is the URL bar. Its absence is what kept me away from Chrome in the first place. That and Chrome's constant failure to render certain HTML pages. I like being able to click the pulldown menu and see sites I visit infrequently but not enough to bookmark. My bookmarks are hard enough to manage without saving every page I visit.To read this article in full or to leave a comment, please click here

Feedback: Layer-2 Leaf-and-Spine Fabrics

Occasionally I get feedback that makes me say “it’s worth doing the webinars ;)”. Here’s one I got after the layer-2 session of Leaf-and-Spine Fabric Designs webinar:

I work at a higher level of the stack, so it was a real eye opener especially with so much opinionated "myths" on the web that haven't been critically challenged such as [the usefulness of] STP.

There’s more feedback on this web page where you can also buy the webinar recording (or register for the next session of the webinar once they are scheduled).

Apple hires mobile encryption pioneer amid encryption debate

Apple has rehired a mobile encryption pioneer as it continues to face pressure from governments wanting access to user data stored on iPhones. Jon Callas most recently worked as a co-founder of Silent Circle, which produced the security-minded Blackphone and has joined the iPhone and iPad maker in an undisclosed capacity, Apple revealed to Reuters. Callas is a veteran of the security industry who also co-founded PGP Corporation.He first worked at Apple from 1995-1997, then again from 2009-2011.
