My mechanical keyboard

You spend all your waking time at a keyboard. This blog post is about keyboards, and can be summarized as: Buy quality, cry once.

I spend a lot of time typing on a keyboard, yet I have never looked into what keyboard would be best for me. There are natural keyboards and kinesis keyboards that people speak well of, but I spend a lot of time typing on laptops and don’t want a completely different setup for laptop and desktop.

I had the same concern before switching to Dvorak back when I was a consultant (thus often using other peoples managed machines), but happily switched after verifying that even on a locked down Windows machine as a non-admin user I could select Dvorak. Also there are adapters from Dvorak to Qwerty that I could use in extremely locked down environments such as the CCIE lab (they required a doctors note though, long story).

So it would have to be a keyboard that looks like a normal one. Preferably with Dvorak on the keycaps. It seems that mechanical keyboards are all the rage, so I thought I’d give that a go.

Upcoming Apple TV will feature App Store and Siri

Amid reports that Apple is planning to roll out its own streaming TV service later this fall, we now have word regarding what Apple's fourth-gen Apple TV is going to look like.Reporting for Buzzfeed, John Paczkowski reports, that Apple plans to show off a completely revamped version of its Apple TV at WWDC sometime this June. And though previous Apple TV updates have been somewhat limited to internal upgrades, this one promises to be a doozy.First off, the next iteration of the Apple TV will reportedly include, at long last, an App Store. Just as the App Store significantly increased the value proposition of iOS devices, we can expect to see a similar transformation with respect to the Apple TV. Even more so when one considers the possibilities of using external controllers, or even one's iOS device, as a controller while playing games on a big screen HDTV.To read this article in full or to leave a comment, please click here

Android’s smart lock now detects when you carry your phone

Google is adding a feature to Android’s smart lock that could significantly cut down on the number of times users need to enter a passcode to unlock their phones while they are out and about.On-body detection uses the accelerometer in the phone to detect when it’s being held or carried by a person. If enabled, the feature requires a passcode the first time the phone is accessed but then keeps the device unlocked until it is placed down.That means, for example, that someone walking down the street won’t have to unlock their phone every time they take it out of their pocket.The feature doesn’t appear to have been announced by Google, but it began appearing in some phones on Friday.To read this article in full or to leave a comment, please click here

Bare-metal switches poised to take off in data centers

Bare-metal switches that can be programmed like Linux servers aren’t just for big Web companies anymore. They may show up in a lot more average enterprises in the next few years.Cloud-based service providers like Facebook and Google have been building data-center networks out of generic hardware and homegrown software for years. Now vendors including HP and Dell are beginning to sell switches much like they do bare-metal servers. They may pre-load an operating system and provide ongoing support, but that OS is open and their customers will have much more freedom with this new kind of gear than they do with traditional switches from vendors like Cisco Systems.To read this article in full or to leave a comment, please click here

China discloses cyberwarfare unit, no one surprised

It came as a shock to just about no one in the cybersecurity industry that China has a cyberware unit, which was acknowledged by the government there this week.While the Chinese government has long denied attacking U.S. targets, U.S. businesses and government agencies have complained for years about attacks originating from China.The Chinese government noted the existence of the country’s cyberwarfare unit in “The Science of Military Strategy,” a publication put out by a research institute of the People’s Liberation Army, according to news reports this week. The U.S. military has acknowledged its own cyberwarfare capabilities for over a decade.To read this article in full or to leave a comment, please click here

Monetizing medical data is becoming the next revenue stream for hackers

The personal information found in health care records fetches hefty sums on underground markets, making any company that stores such data a very attractive target for attackers.“Hackers will go after anyone with health care information,” said John Pescatore, director of emerging security trends at the SANS Institute, adding that in recent years hackers have increasingly set their sights on EHRs (electronic health records).With medical data, “there’s a bunch of ways you can turn that into cash,” he said. For example, Social Security numbers and mailing addresses can be used to apply for credit cards or get around corporate antifraud measures.To read this article in full or to leave a comment, please click here

Routing on the CCIE Data Center Lab – How Deep Do We Need to Go?

Every time I teach NX-OS the same question often arises, “How good do we need to be at routing in order to pass the lab exam?” My first inkling is always to say ‘learn it all,’ but we all know that isn’t always possible. There is a ton of information to learn within the scope of this lab exam, so in order to fully understand this question, we need to look towards Cisco’s almighty guide, the blueprint!

They have gone pretty easy on us in terms of routing, but in their defense, they do have an entire lab dedicated to routing and switching. If we scan down the blueprint to Section 1.2, we see the category we are looking for:

While that comprises that entire section, I would also err on the side of caution and include Section 1.4a grouped within the L3 category, those being first-hop routing protocols such as HSRP, GLBP, and VRRP.

Look at what they ask us for here, and lets analyze it. They ask for BASIC EIGRP and OSPF, Bi-directional forwarding detection, and equal-cost multi-pathing. ECMP isn’t really its own ‘protocol’, rather something that most L3 protocols support. We will see that Continue reading

Net neutrality rules: Separating fact from hype

The net neutrality debate in the U.S. over the past year has been filled with hyperbole, speculation and questionable claims, coming from both sides of the debate.Let’s look at some of the hype and compare it to what we know from the U.S. Federal Communication Commission’s net neutrality order, released last week, and from other information.Four million people in favor of the rulesThere seems to be a misconception, driven as much by media coverage as actual statements by net neutrality advocates, that nearly all of the 4 million comments filed with the FCC in the proceeding were in favor of strong net neutrality rules. There’s some debate over analysis done on the final numbers, but we do know that a substantial number of comments came from people opposed to new rules.To read this article in full or to leave a comment, please click here

Wireless router from Huawei hints at new ways to speed up LTE

In the hunt for more spectrum to offer higher wireless broadband speeds, mobile operators and equipment vendors are showing a growing interest in a new candidate.Huawei Technologies has laid the groundwork for speeds up to 220Mbps using LTE-Advanced at 3.5GHz. On Friday, the company said it has launched the world’s first device, a wireless router, that combines the speedy network technology with that frequency band.The amount of spectrum is one of the things that determines what speeds a network can offer. The 3.5GHz band is an ideal candidate for offering high speeds because it has a lot of spectrum available, according to Huawei. What the vendor does not mention is that using the higher band also means worse coverage than what mobile operators can offer with current networks.To read this article in full or to leave a comment, please click here

Cisco NAT Cheat Sheet

I’ve always had a difficult time when attempting to remember how to implement the different types of NAT available on ASA and IOS devices. It doesn’t help that between the two device families, there are three different syntax versions used in the configurations. I created the PDF linked below as a quick reference sheet. It […]
