‘When will IPv4 become obsolete?’

On Reddit’s forum devoted to networking – r/networking – a user asks: “I know that IPv4 is all out of addresses, and most devices are running both IPv4 and IPv6. How long is it going to take before we no longer see both addresses on a device, but only IPv6? 5 years? 10 years? 20 years? Does anyone have an estimate?”Oh, yes, they do; in fact, 82 Redditors offer their views on the matter. Here are a few that represent the general tenor: Well since I still support IPX for some legacy apps ... in 100 years. Right after POTS dies. And then only after another 30 years. General IPv6 adoption is 18 months away. My college prof told me this in 1995, and he's still right. Not in our career lifetime. IPv6 will take off during the year of the Linux desktop. You'll pull IPv4 from my cold, dead hands... But there were also a fair number of more nuanced replies:To read this article in full or to leave a comment, please click here

Crazy Busy

For too many of us, the hustle and bustle of electronic activity is a sad expression of a deeper acedia. We feel busy, but not with a hobby or recreation or play. We are busy with busyness. Rather than figure out what to do with our spare minutes and hours, we are content to swim in the shallows and pass our time with passing the time.

Server heating startup teams with energy company to heat Dutch homes

A Dutch utility is inviting five families to use radiator-sized servers to heat their living rooms for free.In a trial organized by local utility Eneco, Nerdalize will install its server radiators in five homes, using them to deliver cloud computing services to its clients.The households using the heater could save €400 (about US$440) on their annual heating bill, said Eneco spokesman Marcel van Dun .Nerdalize pays for the electricity, but doesn’t have to deal with the space and cooling costs of conventional cloud and co-location data centers, allowing it to sell its services for 30 to 55 percent less than more conventional cloud-providers, it said.To read this article in full or to leave a comment, please click here

VMware NSX Ninjas – VMware TAM Services

VMware Technical Account Managers combine deep expertise with insights from successful implementations to provide unparalleled value to VMware customers’ business. Curtis Miller is a Technical Account Manager for VMware and in this post, which originally appeared on The VMware TAM Blog, he outlines how to help ensure success with VMware NSX TAM Services.

For networking, VMware NSX is a game-changer in the same way VMware vSphere was for data center servers. NSX virtualizes and consolidates legacy networking functionality back into a hypervisor. As a result, adding or changing network capabilities no longer requires the costly replacement of networking gear. It’s all software based—so upgrades are now just a right-click away.

The resulting cost savings are dramatic because network hardware is replaced far less often and used more efficiently. Deployment times and scalability improve substantially because networks can be created in minutes instead of weeks; and if demand falls, those resources can just as easily be reclaimed. Enhanced security via NSX’s micro-segmentation capabilities is another important benefit as well.

India’s Supreme Court strikes down law against offensive online content

India’s Supreme Court has struck down as unconstitutional an Internet law that provided for the arrest of people sending online messages considered offensive or menacing.The court struck down on Tuesday section 66A of the Information Technology Act, describing it as vague, and said it did not fall under reasonable restrictions on free speech.The decision by the Supreme Court follows a bunch of lawsuits that alleged that this section of India’s cyberlaw was a threat to free speech in the country, and had led to arbitrary arrests.“This is a clear win for democracy and free speech,” said Mishi Choudhary, a lawyer focused on technology. She added that the Supreme Court had proven to be “very tech-savvy.”To read this article in full or to leave a comment, please click here

Whitebox Switching: Follow the R&D Budget

A few weeks ago HP announced that they’d start selling branded whitebox (brite-box) switches, and as expected the industry press was immediately full of opinions. As always, it makes sense to follow the money (or, in this case, the R&D budget) to understand what’s going on behind the scenes.

Beware the pretty ones? This isn’t high school

Normally, I’d be the first to agree with an article whose premise implies that the nature of the tech industry is changing, because when is it not? However, I’m not sure I agree with the central premise of this article by Jon Evans at TechCrunch. He asserts that the tech industry was originally the personal playground of geeks and has become co-opted by the “cool kids” as the industry has matured and grown.  

It is true, as Evans contends, that many geeks are motivated more by the work than by impressing other people or making money, and that the tech industry probably offers more opportunities to people like that than some other industries.

But I think Evans’ idea of the geek vs. the pretty people is, well, short-sighted, and kind of “high schoolish.”  It is not us vs. them - there isn’t even an us or them. “People skills” and “technical skills” are not mutually exclusive.  And they never have been.

Yes, it is true that the tech industry has been the go-to “safe haven” for technically minded, socially awkward people, Continue reading

US FCC faces lawsuits against proposed net neutrality order

U.S. broadband industry trade body USTelecom and Internet provider Alamo Broadband filed Monday lawsuits against a controversial U.S. Federal Communications Commission proposal to reclassify broadband providers, which could be the harbinger of similar lawsuits from Internet companies.The FCC voted by 3-2 in February to approve new net neutrality rules that would help ensure the uninhibited flow of Internet traffic. It aims to reclassify broadband as a regulated public utility, thus prohibiting providers from selectively blocking or throttling or offering paid prioritization of traffic.To read this article in full or to leave a comment, please click here

Google catches bad digital certificates from Egyptian company

Google said Monday an Egyptian company issued digital certificates that could have been used to intercept data traffic to its services, which did not appear to have been abused.The incident is the latest example of longstanding problems around the issuance of digital certificates, which are used to encrypt data and verify the legitimacy of websites.Google detected on March 20 that unauthorized digital certificates had been issued for several of its domains by MCS Holdings, a Cairo-based networking and security company, wrote Adam Langley, a Google security engineer.To read this article in full or to leave a comment, please click here

Twitter tests videos that play automatically

Twitter has started to let videos play automatically in some people’s feeds, in a test that could allow it to make more money from video advertising.The videos will play automatically for a small percentage of people who use Twitter’s iOS app in the U.S. “We’re running a small test on a few variations on the video playback experience,” a Twitter spokesman said.The test, first reported by Advertising Age, applies both to videos uploaded by users and to those posted by advertisers, but it doesn’t apply to looped videos from Twitter’s Vine service.To read this article in full or to leave a comment, please click here

Imagination floats sub-$100 MIPS tablet running Firefox OS

With Android and iOS dominating the tablet market, Mozilla’s Firefox OS hasn’t had much of a look in. It’s now getting a bit of help from ARM rival Imagination Technologies, which has ported a version of Firefox to a prototype tablet based on its MIPS chip architecture.The tablet is a reference design built by China’s Ingenic and it’s designed to be priced under $100. It can run either Android 4.4, known as KitKat, or an experimental version of the Firefox OS, Imagination said in a blog post.It’s designed to help Imagination and Mozilla target the market for very low cost tablets sold in emerging markets like Brazil and India.To read this article in full or to leave a comment, please click here

Seth Rogen will play Steve Wozniak in the next Steve Jobs biopic

Freaks and Geeks alum Seth Rogen is set to play the Mac community’s favorite ubergeek Steve Wozniak in the upcoming Steve Jobs biopic (no, not that one, the other one), alongside Christian Bale as Steve Jobs. Hopefully it won’t be Superbad. (Sorry.) The news comes from Variety, which also reported that “Jessica Chastain is being eyed for an unspecified role.” Perhaps that’ll be a composite character of every woman in Jobs’s orbit—after all, last year’s Jobs (the one starring Ashton Kutcher) was seriously bereft of women actors who weren’t playing Steve’s mother, wife, or girlfriend.To read this article in full or to leave a comment, please click here

How to create a GitHub pull request (PR)

Being a network engineer, Git is not something that I used to use very frequently before I started messing around with Kubernetes.  It can be a frustrating tool to work with if you don’t know exactly what you’re doing.  And while it tries to help you from cutting yourself, it’s pretty easy to lose code you’ve worked on if you aren’t careful.  On the flip side, once you learn the basics it’s a very awesome tool for all kinds of revision tracking.

While playing around with the newest Kubernetes binaries I noticed a issue with the ‘fluentd-elasticsearch’ add-on in my lab.  After some debugging, I think I found the issue so I’d like to suggest a change to the code to fix it.  This is what’s called a ‘pull request’ or often just a ‘PR’.  A PR means you are submitting a request to ‘pull’ new code into the active repository.  Once your PR is submitted, people have a chance to review and comment on your suggested changes and if everything looks good, it will get pulled into the repository.  So I thought it would be good to document this PR so Continue reading
