Tim Cook: Apple won’t shrink in fight for data privacy

Apple won't shrink from its responsibility to safeguard the privacy of its users, CEO Tim Cook said Monday, a day before Apple lawyers are due to face off with the Department of Justice in a California courtroom.Cook's comments confirm the company's continued defiance against a request from the FBI to develop software that will allow it to make multiple guesses of an iPhone passcode without triggering the phone's self-destruct feature."I've been humbled and deeply grateful for the outpouring of support that we've received from Americans across the country from all walks of life," said Cook at an event in Cupertino held to announce new products. "We believe strongly that we have a responsibility to help you protect your data and your privacy."To read this article in full or to leave a comment, please click here

Leaked Clinton email shows Google wanted to help overthrow Syrian President

Last week WikiLeaks launched the Hillary Clinton email archive; it’s described as “a searchable archive for 30,322 emails & email attachments sent to and from Hillary Clinton's private email server while she was Secretary of State. The 50,547 pages of documents span from 30 June 2010 to 12 August 2014. 7,570 of the documents were sent by Hillary Clinton.”The Washington Examiner honed in on an email from 2012 that was forwarded to Clinton after her deputy chief of staff noted that it was a “pretty good idea.” It is supposedly proof that Google wanted to help insurgents overthrow Syrian President Bashar Assad. It seems like the State Department, Google and Al Jazeera were all in cahoots.To read this article in full or to leave a comment, please click here

The Design Mindset (2)

In a comment from last week’s post on the design mindset, which focuses on asking what through observation, Alan asked why I don’t focus on business drivers, or intent, first. This is a great question. Let me give you three answers before we actually move on to asking why?

Why can yuor barin raed tihs? Because your mind has a natural ability to recognize patterns and “unscramble” them. In reality, what you’re doing is seeing something that looks similar to what you’ve seen before, inferring that’s what is meant now, and putting the two together in a way you can understand. It’s pattern recognition at it’s finest—you’re already a master at this, even if you think you’re not. This is an important skill for assessing the world and reacting in (near) real time; if we didn’t have this skill, we wouldn’t be able to tolerate the information inflow we actually receive on a daily basis.network-design-mindset-01

The danger is, of course, that you’re going to see a pattern you think you recognize and skip to the next thing to look at without realizing that you’ve mismatched the pattern. These pattern mismatches can be dangerous in the real world—like the time I Continue reading

Picking Up the Baton

Josh-Leslie-JR-Rivers

I’m incredibly excited and honored to take on the role of CEO of Cumulus Networks. In many ways, I’ve trained for this role my whole life. I grew up in Silicon Valley. I have had a front row seat to the growth of the tech economy and been fortunate to watch many passionate leaders grow companies from simple concepts to multi-million dollar firms. I couldn’t be more committed than I am today to bringing a lifetime of experience and learning to bear in leading Cumulus Networks to its next phase.

First and foremost, thank you, JR, for entrusting me with this enormous responsibility. JR and Nolan have both invested their hearts, souls and many years of their lives in Cumulus Networks. They have hired incredible people, built great products, signed impactful partnerships and — in a brief few years — have already had a profound impact on this industry. They have fundamentally changed how networking products are bought, sold, developed and deployed, and in the process spawned a legion of imitators. I’m honored to be entrusted with the job of moving this organization forward. JR and I bring incredibly complementary skills to the table; he is a technical visionary and Continue reading

Finding Level

Josh-Leslie-JR-Rivers

Nolan and I started Cumulus Networks with a specific vision: to help people build better, faster, easier networks.  To change the way that people think about building and deploying applications, regardless of scale. A lot of people have contributed into turning this vision into reality, and we’re excited by everything that we’ve achieved.

As we closed our series A, it was time to name a CEO, and we didn’t want to trust the company to a “professional CEO”. To that end, I took on the responsibility. In the early days I was able to stay involved with the technology and products; however, as the company has progressed, I’ve had less time to spend in the areas that motivated me to start the company.

Then along came Josh.  He participated in our extensive (some would say exhaustive) VP of Sales selection process and stood out.  His ability to grasp the business details as well as manage the team dynamics showed us that he has chops.  He joined us in June of 2015 and continued to impress.  He did his day job effectively by restructuring our sales team, refining the sales process, getting operations tight, and closing deals.  He also became a Continue reading

Johns Hopkins team cracks iMessage photo, video encryption

A Johns Hopkins team has decrypted iMessage photos by guessing character-by-character the key used to encrypt it, and Apple plans to release a new iOS version today that will fix the flaw.Upgrading to iOS 9.3 should fix the problem for users of the operating system and iMessage, says Matthew Green, a computer science professor at Johns Hopkins who led a team of grad students that broke the encryption, according to a story in the Washington Post.The story says he discovered a flaw in the encryption last fall and told Apple about it, but when months went by and nothing was done to patch it, he turned his team loose. Here’s how the Post describes the attack:To read this article in full or to leave a comment, please click here

To Compress or Not to Compress, that was Uber’s Question

Uber faced a challenge. They store a lot of trip data. A trip is represented as a 20K blob of JSON. It doesn't sound like much, but at Uber's growth rate saving several KB per trip across hundreds of millions of trips per year would save a lot of space. Even Uber cares about being efficient with disk space, as long as performance doesn't suffer. 

This highlights a key difference between linear and hypergrowth. Growing linearly means the storage needs would remain manageable.  At hypergrowth Uber calculated when storing raw JSON, 32 TB of storage would last than than 3 years for 1 million trips, less than 1 year for 3 million trips, and less 4 months for 10 million trips.

Uber went about solving their problem in a very measured and methodical fashion: they tested the hell out of it. The goal of all their benchmarking was to find a solution that both yielded a small size and a short time to encode and decode.

The whole experience is described in loving detail in the article: How Uber Engineering Evaluated JSON Encoding and Compression Algorithms to Put the Squeeze on Trip Data. They came up with a matrix of Continue reading

Worth Reading: Improving Communication

You’d think that after all these years of technology being a driving force behind business growth, there’d be similarly strong communication links between IT and business leaders. Alas, it’s still the case that those kinds of close relationships remain the exception rather than the rule. Let’s face it, even IT executives and the engineers or analysts who report to them sometimes seem to be speaking different languages. -via Netcraftsmen

27% of US office workers would sell their passwords

In a survey released today, 27 percent of of U.S. office workers at large companies would sell their work password to an outsider, compared to a global average of 20 percent.And despite all the recent media attention on data breaches, password hygiene is actually deteriorating, said Juliette Rizkallah, CMO at SailPoint Technologies, which sponsored the survey.The study itself was conducted by Vanson Bourne, an independent research firm. The same survey was conducted last year as well, but then only one in seven employees were willing to sell their passwords.To read this article in full or to leave a comment, please click here

How Hard Is It to Think about Failures?

Mr. A. Anonymous, frequent contributor to my blog posts left this bit of wisdom comment on the VMware NSX Update blog post:

I don't understand the statement that "whole NSX domain remains a single failure domain" because the 3 NSX controllers are deployed in the site with primary NSX manager.

I admit I was a bit imprecise (wasn’t the first time), but is it really that hard to ask oneself “what happens if the DCI link fails?”
