Bacony goodness + math + 3D printing = an inedible endless Bacon Möbius strip

If you take a strip of bacon and twist one end through 180 degrees then join the two ends you get a piece of bacon with only one side, a Bacon Möbius strip. Cool. But if you want such a thing to adorn your desk (and who wouldn't?) then being made of real bacon would be, to say the least, a bad idea. So,  to memorialize this mathematical and culinary wonder, why not print a look-alike on a 3D printer? Why not indeed?

This exactly is what a designer with the handle "joabaldwin" created using the Shapeways 3D printing service.

Apple Watch pre-orders to begin at 12:01 Pacific Time on April 10

Apple on Friday afternoon updated its Apple Watch page with more precise details regarding Apple Watch pre-orders. According to Apple's website, pre-orders for Apple's highly anticipated wearable will begin at 12:01 AM Pacific Time  on Friday, April 10. Of course, this doesn't bode well for prospective buyers on the East Coast who will have to wait up until 3:01 AM in order to get their orders in.The latest reports from the rumor mill suggests that the Apple Watch will not be available to walk-in shoppers. Which is to say, if you want to get your hands (or wrist, as it were) on an Apple Watch, you absolutely must pre-order the device or make a reservation to check one out in-store. Presumably, walk-in sales will eventually be possible once supply is properly calibrated to match demand.To read this article in full or to leave a comment, please click here

My CLUS 2015 Schedule for San Diego

With roughly two months to go before Cisco Live starts, here is my preliminary schedule for San Diego.

CLUS San Diego Schedule

I have two CCDE sessions booked to help me prepare for the CCDE exam. I have the written scheduled on wednesday and we’ll see how that goes.

I have a pretty strong focus on DC because I want to learn more in that area and that should also help me prepare for the CCDE.

I have the Routed Fast Convergence because it’s a good session and Denise Fishburne is an amazing instructor and person.

Are you going? Do you have any sessions in common? Please say hi if we meet in San Diego.


What’s In My Bag (Hint: not much)

Recently @BobMcCouch posted a photo of the contents of his bags. He’s got a lot of gear, including a hammer, and a dent-puller. He assures us that it’s for lifting tiles, but I’m not so sure. Sounds to me like he’s worried about a few dings in the supermarket carpark.

It all sounded a bit scary. I want to provide a different perspective, that of someone who tries to minimise what they carry. I don’t want young engineers to think that they have to build up a huge toolbox, and the physical strength to lug it around. You might choose to do that, but it’s not the only path.

Note: I am not saying that what Bob is doing is wrong. Bob’s a smart guy, and if he’s carrying all that stuff, you can be sure it’s for a reason. What I’m trying to say is that there are different paths in network engineering.

The Bag Itself

My general rules for a laptop bag are that it should be as small as I can get away with, and it should not look too much like a laptop bag. So pretty much anything from Targus is inappropriate.

Today I use the “ Continue reading

Power up, baby! Cyntur JumpStart Mini: A monster backup battery in a tiny package

The market for portable battery packs to keep your digital life going on the road has become a huge business over the last couple of years and I just got my hands on one of the more versatile and powerful products in this market: The Cyntur JumperPack mini. This is a small (6.0” by 3.3” by 1.3”), weatherproof device that weighs just 0.9 pounds but despite its diminutive size contains a whopping 12,000 mAh lithium-ion battery, enough to jumpstart an eight-cylinder engine. Not only that but it's powerful enough, the company claims, to jumpstart 25 engines in a row (a problem I hope to never have).To read this article in full or to leave a comment, please click here

US gains in mobile patents as IBM passes Samsung

The U.S. widened its lead in mobile patents last year and IBM took the top spot in new patents granted in that space, according to a report this week that analyzed data from both the U.S. and Europe.While the number of mobile patents granted by the U.S. Patent and Trademark Office (USPTO) jumped by 17 percent between 2013 and 2014, the total fell by 4 percent at the European Patent Office (EPO), according to Chetan Sharma Consulting. The U.S. continued to gain on Europe as the place where mobile inventions are devised, a trend driven by software development in Silicon Valley and Americans’ heavy use of mobile data, the report said.To read this article in full or to leave a comment, please click here

The .onion address

A draft RFC for Tor's .onion address is finally being written. This is a proper thing. Like the old days of the Internet, people just did things, then documented them later. Tor's .onion addresses have been in use for quite a while (I just setup another one yesterday). It's time that we documented this for the rest of the community, to forestall problems like somebody registering .onion as a DNS TLD.

One quibble I have with the document is section 2.1, which says:

1. Users: human users are expected to recognize .onion names as having different security properties, and also being only available through software that is aware of onion addresses.

This certain documents current usage, where Tor is a special system run separately from the rest of the Internet. However, it appears to deny a hypothetical future were Tor is more integrated.

For example, imagine a world where Chrome simply integrates Tor libraries, and that whenever anybody clicks on an .onion link, that it automatically activates the Tor software, establishes a circuit, and grabs the indicated page -- all without the user having to be aware of Tor. This could do much to increase the usability of the Continue reading
