The right tool for the job

This last weekend I set a toilet, replaced five faucets, and put together the beginnings of a workbench. No, I’ve not resorted to working in “the trades,” to make a living — I’ve been slowly but surely finishing and refashioning our “country house” to better accommodate the time we spend “in the country.” One of the faucets, and the toilet, were set in a new bathroom; the pipes had been stubbed up but not finished — which means there were no valves. After the adventure of finding the main water cutoff for the house (it’s buried under about three inches of dirt along one side of the foundation), I had to cut off the plugs and install valves.

The pipes in the country house are PEX. So are the pipes in the house we just moved from. In fact, so are the pipes in the house in Raleigh we just moved to. Odd thing, that — three houses, in different places, at different price levels, and they all use PEX piping. In fact, walking through some random retail store last week, I noticed they had PEX stub outs in a bathroom there, too.

Imagine walking into an apartment and Continue reading

Wearable security: Two-factor authentication apps for Apple Watch

The Apple Watch could become our central hub in a wheel of identity, in which all spokes rotate around our wrist. Some early Watch apps already have a high degree of utility. But we’re only scratching the surface of what’s to come.MORE: 10 mobile startups to watch In this roundup, we look at six apps that offer varying forms of authentication on the Watch. Three allow a tap on the Watch to unlock something: an account, a login, a computer, or more. The other three handle the most common form of app-generated second-factor authentication codes.To read this article in full or to leave a comment, please click here

The Upload: Your tech news briefing for Monday, June 1

Once again, reports have Intel near a deal with AlteraIntel may announce a deal to acquire FPGA maker Altera on Monday, the Wall Street Journal reports, after the two companies returned to the bargaining table following a failure to come to terms earlier this year. The buy would strengthen Intel’s already dominant hand in the server market at a cost of about $17 billion.NSA surveillance powers expire as Senate delays voteA controversial program allowing the U.S. National Security Agency to collect millions of domestic telephone records expired Sunday night after the Senate failed to vote on a bill to extend the authority for the surveillance. But senators moved closer to bringing the USA Freedom Act to a vote; that bill gives the agency limited power to obtain data on American residents under investigation. Some are still calling for more reform and better oversight.To read this article in full or to leave a comment, please click here

Chromebooks with MediaTek chips to appear ‘very soon’

Chip maker Mediatek is preparing to enter the laptop business, with the first Chromebooks based on its processors due to appear soon.So said Mediatek senior vice president Jeffrey Ju at the Computex trade show in Taipei. The company also showed a non-working Chromebook with its 64-bit MT8173 quad-core processor and a USB Type-C port.Ju didn’t say exactly when PC makers will release Chromebooks with MediaTek’s chips, but another MediaTek representative said the laptops could appear in the second half of this year or early next year.Chromebooks, which run Google’s Chrome OS, are catching on as a low-cost alternative to Windows PCs for users who do most of their computing on the Internet. The usage model is much like tablets and smartphones, with most applications requiring an Internet connection, though Google is making more offline applications available.To read this article in full or to leave a comment, please click here

Overhead projector vs. ceiling fan

So what do we have here?First of all, I cannot vouch for the authenticity of this photograph. I received it via the Twitter account for YouHadOneJob, @_youhadonejob. There are several other versions floating around. It could be a fake. But let’s assume it’s real. What could account for the decision of the projector installer?Perhaps it could be that the projector needed to be installed a precise distance from the screen and therefore no other variable, such as proximity to the blades of a ceiling fan, could alter that requirement. In other words, the projector installer simply had no choice.To read this article in full or to leave a comment, please click here

Internet of Things breathes new life into RFID technology

About a decade or so ago, it was almost impossible to find a tech analyst who wasn't predicting that radio-frequency identification (RFID) would soon change the world. While RFID eventually became a useful tool in retail, logistics, healthcare and a handful of other enterprise sectors, the technology largely lurked in the shadows while other truly transformative concepts, such as social media and streaming entertainment, grabbed the spotlight.To read this article in full or to leave a comment, please click here(Insider Story)

First Look: Amazon Echo: Novelty item or ready-for-prime-time part of your digital life?

Our Amazon Echo, a voice-controlled appliance—for want of a better word—arrived on May 17 and we’ve been using it all week. As Prime members, we paid $100 for ours, but the list price is $200. While some parts are beautifully done, the information services at the back end have a long way to go before the Echo is more than a novelty.The Echo is a heavy cylinder, about nine inches tall and three inches in diameter. Colored black, it sits inconspicuously anywhere you can get it AC power and a Wi-Fi connection. (Wired Ethernet is not included) Most of the Echo is made up of speakers, which gives you an idea of what the Echo is best at: playing music.To read this article in full or to leave a comment, please click here

ARM hopes to extend battery life of IOT devices with new chip design

ARM is trying to resolve the thorny problem of battery life in Internet of Things devices with a new chip design that will significantly reduce the power consumed by processors, sensors and wireless chips.The company has overhauled the way it designs low-power Cortex-M chips that go into IoT devices such as health monitors, smart home devices and sensors. The restructured design could almost double battery life, ARM executives said at Computex in Taipei on Monday.For example, the battery life of a connected hearing aid could more than double with chips based on the new design, said Jeff Chu, director of marketing at ARM.Chu provided another example of a smart lightbulb lasting a lot longer on a battery charge with new chips based on the design. The smart bulb could have solar cells to refresh the battery, and the chip’s lower power consumption could help the battery last for years.To read this article in full or to leave a comment, please click here

Case Study: Scale-Out Cloud Infrastructure

I helped several customers design scale-out private or public cloud infrastructure. In every case, I tried to start with a reasonably small pod (based on what they’d consider acceptable loss unit – another great term I inherited from Chris Young), connected them to a shared L3 backbone (either within a data center or across multiple data centers), and then tried to address the inevitable desire for stretched layer-2 connectivity.

You’ll find a summary of these designs in my next ExpressExpress case study: Scale-Out Private Cloud Infrastructure, and if you need more details, I’m usually available for online consulting.

Apple vulnerability could allow firmware modifications, researcher says

A zero-day software vulnerability in the firmware of older Apple computers could be used to slip hard-to-remove malware onto a computer, according to a security researcher.Pedro Vilaca, who studies Mac security, wrote on his blog that the flaw he found builds on previous ones but this one could be far more dangerous. Apple officials could not be immediately reached for comment.Vilaca found it was possible to tamper with an Apple computer’s UEFI (unified extensible firmware interface). UEFI is firmware designed to improve upon BIOS, which is low-level code that bridges a computer’s hardware and operating system at startup.To read this article in full or to leave a comment, please click here

Cloud gaming at 4K still years away, Nvidia CEO says

Don’t expect online games to stream to your TV or PC at 4K resolution anytime soon.While it is possible to stream 4K movies from online services like Netflix to PCs, TVs and set-top boxes, streaming games from the cloud requires many infrastructure changes, said Jen-Hsun Huang, CEO of Nvidia, during a media briefing at Computex.Nvidia can currently stream 1080p games at 60 frames per second from its Grid online gaming service, but the technology needs to be developed for 4K streaming and a lot of fine-tuning is needed at the server level, Huang said.“It’s going to be a while,” Huang said.Many 4K TVs and monitors are already available, and display images at the 3840 x 2160-pixel resolution. Games typically require two-way communications, and servers process bits related to games differently than video streams.To read this article in full or to leave a comment, please click here
