5 things I learned living with just a smartphone for two weeks

I recently returned from a 12-day vacation in Peru and, because I was going to be moving around a lot, I decided to brave the trip with just my iPhone 6 Plus. No laptop. No tablet. And only the lowest-level AT&T Passport international roaming plan: $30 for 30 days of $1/min phone calls, unlimited texting, and a minuscule 120MB of data.As it turned out, I did pretty well. Since this was a vacation, I wasn't planning on doing any real work, just monitoring email to make sure nothing important was blowing up back home, and passing along urgent (and semi-urgent) emails that couldn't wait for my return.To read this article in full or to leave a comment, please click here

CloudFlare is now a Google Cloud Platform Technology Partner

alt

We’re excited to announce that CloudFlare has just been named a Google Cloud Platform Technology Partner. So what does this mean? Now, Google Cloud Platform customers can experience the best of both worlds—the power and protection of the CloudFlare community along with the flexibility and scalability of Google’s infrastructure.

We share many mutual customers with Google, and this collaboration makes it even easier for Google Cloud Platform customers to get started with CloudFlare.

How does it work?

When CloudFlare is enabled, Google Cloud Platform customers have their infrastructure extended directly to the network edge, giving them faster content delivery as well as heightened optimization and security.

Benefits Include:

  • 2x Web Performance Speed - CloudFlare uses advanced caching and the SPDY protocol to double web content transfer speeds, making web content transfer times significantly faster.

  • Datacenters at Your Customer’s Doorstep - CloudFlare’s global edge network caches static files close to their destination, meaning that content always loads fast no matter where customers are located. Also, CloudFlare peers with Google in strategic locations globally, improving response times for Google Cloud Platform services.

  • Protection Against DDoS and SQL Injection Attacks - Because CloudFlare sits on the edge, customers are protected from malicious traffic Continue reading

Files encrypted by CoinVault ransomware? New free tool may decrypt them

Victims of the CoinVault ransomware might be able to decrypt their files with a free tool released by Kaspersky Lab together with the Dutch police.The tool can be found at https://noransom.kaspersky.com. The application uses decryption keys found by the Dutch police as part of an investigation.Ransomware like CoinVault encrypts data on a disk or blocks access to a computer system. It is usually installed by exploiting a vulnerability on victims’ computers via phishing emails or links to malicious websites.Unlike other ransomware, CoinVault lets victims see a list of the files it encrypted and decrypt one for free to try to get people to pay up.To read this article in full or to leave a comment, please click here

Five Functional Facts about EIGRP

Normally for these FFF articles I’ve taken to writing about new protocols as a way of introducing others to it and also edumacating myself about it. For this post I get all nostalgic and look at good old Enhanced Interior Gateway Routing Protocol (EIGRP).

1 – The EIGRP Metric is Calculated From a Formula

Unlike RIP with its simple hop count or OSPF with its simple bandwidth metric, the EIGRP metric is actually derived by plugging a number of values into a formula and solving the formula. The formula looks like this:

EIGRP_Classic_Formula

EIGRP Classic Mode Formula

Let’s talk about the k values first. The k values are constants that are configured in IOS and fed into the formula. They have the affect of basically turning on and off the variables that are used in the calculation: bandwidth, delay, load, reliability. They also have the affect of giving more or less emphasis to a variable. For example, setting k3 to 50 would give the “delay” variable more emphasis than if k3 is set to 1. The default settings for the k values are:

  • k1 and k3 = 1
  • k2, k4, k5 = 0

This has the net result of simplifying the Continue reading

After U.S. chip block, China’s plan for 100 petaflop supercomputer may get delayed

The U.S.’s recent denial of Intel chips for China’s fastest supercomputer could derail an upgrade to double the machine’s processing power.China’s Tianhe-2 is the world’s fastest supercomputer with a theoretical peak speed of 54.9 petaflops. It was scheduled to be expanded, and reach a new peak speed of 100 petaflops this year.Now those plans may be in jeopardy. The U.S. government claims the Tianhe-2 has been used in “nuclear explosive activities”, and has forbidden Intel from shipping its Xeon chips to four related Chinese supercomputing centers.To read this article in full or to leave a comment, please click here

Freedom to

Pardon me if I go a little bit on the philosophical side of life as a network engineer this week, but we need to have a little talk about freedom. This last week, Ethan wrote a post on his new criteria for network design and architecture. While I agree with the points Ethan makes in his post, there was one thing that put me sideways. In fact, this one thing has always put me sideways to our modern world.

Freedom.

Ethan gives what is a pretty standard (Lockian) definition of the idea when he says, “Freedom is the power or right to act, speak or think as one wants without hindrance or restraint.”

But, harking back to the story of Ishmael and Isaac, we need to remember there is a real difference between freedom from and freedom to. Freedom from constraint might feel like real freedom, but it’s the freedom of the wilderness. Freedom to create might feel like slavery with its self-discipline and bounds, but it’s the freedom to build — to create.

Let’s turn to one of Ethan’s examples here — open standards, and vendors sticking to them, to bring the point to the world of network Continue reading

Schneier on ‘really bad’ IoT security: ‘It’s going to come crashing down’

Bruce Schneier Security expert Bruce Schneier has looked at and written about difficulties the Internet of Things presents - such as the fact that the “things” are by and large insecure and enable unwanted surveillance– and concludes that it’s a problem that’s going to get worse before it gets better.To read this article in full or to leave a comment, please click here

The shocking truth (and lies) about ESD

A participant in Reddit’s forum devoted to networking asks: “Has anyone here ever destroyed anything via ESD (electronic static discharge)?”Oh, yes, indeed they have, as a sampling of the anecdotes will reveal, though there were also skeptics and one fellow who told me via email “that most failures claimed to be ESD-related are probably covers for something else.”First time for everything I recently had a user plug an HDMI cable into a Dell E7440. He was touching the shielding and a nice big blue spark jumped from the cable to the laptop and cooked the motherboard. It was the first time in 12 years doing IT that I've ever seen something die from ESD.To read this article in full or to leave a comment, please click here

RFCs You Should Know: 5218

Quite often RFCs in the “earlier days” discussed not only process but also design. Looking back now, considering the complexity of the network engineering world, these RFCs might seem even a little trite. But these “architectural RFCs” often still carry thoughts and records of experience that are important, even if they aren’t so much followed […]

Apple Watch orders nearly topped 1 million on first day – Report

While we won't have official figures on Apple Watch orders until Apple issues a statement, some preliminary figures suggest paint a rosy picture for Apple.According to the research firm Slice Intelligence, Apple Watch orders on day 1 nearly topped one million units. The report was initially relayed by QZ which summarized pertinent portions of the report as follows: Almost two-thirds of pre-orders were for the less expensive, aluminum Sport line, which starts at $349. About one-third of pre-orders were for the stainless-steel Apple Watch collection, which starts at $549. The gold “Edition” series, which starts at $10,000, didn’t represent enough US pre-orders to show up in Slice’s report.To read this article in full or to leave a comment, please click here

FCC net neutrality rules published to Federal Register

The new net neutrality rule of the U.S. Federal Communications Commission was published over the weekend to the Federal Register, the daily journal of U.S. government actions, raising the possibility of a spate of lawsuits from broadband companies that oppose the rule.The FCC decided in a 3-2 vote in February to reclassify broadband as a regulated public utility, by invoking Title II of the Communications Act, thus prohibiting providers from selectively blocking or throttling or offering paid prioritization of Internet traffic.The new rules apply to both fixed and mobile broadband Internet access services. They aim to regulate both services on the lines of traditional telephone companies, which are required to deliver service at “just and reasonable” rates and interconnect with each other.To read this article in full or to leave a comment, please click here

Chinese hacker group among first to target networks isolated from Internet

An otherwise unremarkable hacking group likely aligned with China appears to be one of the first to have targeted so-called air-gapped networks that are not directly connected to the Internet, according to FireEye.The computer security firm released a 69-page technical report on Sunday on the group, which it calls APT (Advanced Persistent Threat) 30, which targeted organizations in southeast Asia and India.FireEye picked up on it after some of the malware used by the group was found to have infected defense-related clients in the U.S., said Jen Weedon, manager of strategic analysis with FireEye.To read this article in full or to leave a comment, please click here
