IDG Contributor Network: What Wi-Fi looks like

Hackaday member CNLohr has created some stunning images of a Wi-Fi network using a remarkably simple technique. He documented his experiments on his Hackaday project page.He achieved the results by capturing wireless signal strength using a Wi-Fi chipset hooked up to a single multi-color LED. The LED rapidly changes color depending on signal strength. He then captures long-exposure photographs of the LED, as his buddy, holding the piece of kit, moves around a space. The result is a multi-colored graphic with variations representing signal strength.Pinging the chipsetTo read this article in full or to leave a comment, please click here

Apple plans two European data centers running on renewable energy

Apple plans to open two European data centers running on renewable energy in 2017, following similar moves by Google and Facebook in the region.The new data centers will host a number of Apple services for European customers, including the iTunes Store, App Store, iMessage text messaging service, Apple Maps and Siri, its voice-controlled personal assistant. By hosting the data within the European Union, Apple could avoid the need to export EU users’ data to the U.S. or other data protection regimes, a sensitive issue as EU legislators discuss renewing the bloc’s data protection regime.Apple plans to spend a total of €1.7 billion (US$1.9 billion) on the two data centers, which will each cover around 166,000 square meters.To read this article in full or to leave a comment, please click here

This man pressed Print. What happened next left me speechless.

HP_X551dw

Although I attended HP Discover in Barcelona as a guest of the folks at HP Networking (via their Independent Bloggers program), I didn’t restrict myself to looking at etherstuff; HP makes way too broad a portfolio of products to get away with that. I ended up looking at printers, and I found something that pretty much blew me away.

Before I forget, please accept my apologies for the clickbait headline. I’ve always wanted to do one of those; but unlike so many others I’ve seen, I hope that this article won’t disappoint. You’ll see “the man” in the headline in a video later.

A Sign of the Times

It was hard to miss at HP Discover that HP believes in eating their own dog food. The signage at the event – many large, inspiring, multicultural images reminding us that HP’s mission is to provide “solutions for the New Style of IT” – was all printed on HP printers. The signs looked pretty amazing, I have to say:

Not only were they printed using HP products, but the poster tells you which printer was used, you know, in case you wanted to buy one for your spare bedroom or something:

New teaser images and video help confirm details of Samsung’s Galaxy S6

With less than a week left until the event at which Samsung Electronics is expected to launch the Galaxy S6, two new images and a video of the company’s next high-end smartphone seem to confirm its name and the presence of a curved screen.The images, posted by Samsung and network operator T-Mobile U.S., show the smartphone from the side. The T-Mobile image has the tagline “six appeal” and shows the side of the device lit up, all but confirming the name and the expected launch of a device with a curved screen that wraps around one or both edges. Samsung first used such a curved screen on the Galaxy Note Edge, which it announced last year.The T-Mobile image along with another image Samsung has posted on Twitter also tease an improved design, which the Galaxy S6 needs if Samsung wants the smartphone to be a bigger hit its predecessor.To read this article in full or to leave a comment, please click here

Startup Flex Logix aims to score big in a niche chip market

In Silicon Valley, where software startups are the rage, it’s unusual to see a new hardware company set up shop. But venture capital-backed chip design company Flex Logix has some big ideas about how to speed up a whole range of software applications and hardware.Flex Logix is establishing a business around FPGAs (field-programmable gate arrays), which are reconfigurable chips that can help hardware run specific applications faster. A notable FPGA user is Microsoft, which has implemented the chips in data centers to quickly deliver more relevant Bing search results.PCs and servers today run on general-purpose processors like CPUs, but FPGAs are different, with functionality defined mainly through software on the chip. Flex Logix claims it has designed a new type of FPGA, which it hopes will be used in networking, telecommunications, servers, military equipment and other hardware.To read this article in full or to leave a comment, please click here

LG takes aim at Motorola’s Moto G with new Magna smartphone

LG Electronics has announced four new smartphones, including the Magna. The device has a spec that gives Motorola Mobility’s Moto G a run for its money, assuming LG doesn’t screw up the pricing too much.Motorola has had the market for unlocked smartphones costing US$200 or less largely to itself in the U.S. and Europe, helping it regain its footing with the Moto G and the Moto E. But it seems the now Lenovo-owned company will face some tougher competition this year from products like the LG Magna.The Lollipop-based smartphone has a 5-inch, 720 x 1280-pixel screen and an unspecified 1.2GHz or 1.3GHz quad-core processor. The Magna also has an 8-megapixel front camera and a 5-megapixel camera on the back. There’s 1GB of RAM and 8GB of integrated storage backed up by a microSD card slot.To read this article in full or to leave a comment, please click here

When backup Is a disaster

Shortly after Branndon Kelley joined American Municipal Power (AMP) as CIO, the company's financial system went down.It took four days to restore the system and Kelley, who had previously consulted with state governments on business continuity issues, immediately started exploring AMP's backup and recovery strategy.He quickly discovered that there was none. No coherent plan. "We had a whole bag of tricks," Kelley says, including more than 10 different backup systems and processes. There were outdated off-the-shelf packages and hand-coded scripts--none of them documented or interconnected. There were backups of backups, and fewer than half of the backups succeeded on the first try.To read this article in full or to leave a comment, please click here

Getting Inside the Loop

Metadata doesn’t just apply to data science or protocols — it applies to engineering life. Think about the concept of epistomology — the study of how we know what we know — or the concept of hermeneutics — the study of how we understand communication — and you can quickly see that stepping outside what we are doing to examine how we are doing it is a common human experience (see Lewis’ Meditation in a Tool Shed as another instance).

But how does this apply to the engineering life? It’s called process — now, before you click off the page, scurrying away in shock, process isn’t a bad thing. In fact, process can be a good set of “guard rails” in the way we live our lives, something to remind us not to run off the road (like positive thinking signs), or even physically/mentally “bump” us in the right direction.

This week I’d like to kick off a short series on one process I learned in the US Air Force, and have used in many ways over the years — the OODA Loop. Originally developed by USAF Colonel John Boyd, and designed to help pilots deal with Continue reading

10 products you could only find at RadioShack

Remembering the ShackRadioShack announced recently that after 94 years the company would be going into bankruptcy, selling off a number of stores and shutting some others down. As a techy who was born in the 60s, RadioShack was a huge part of my life. I remember hitting the RadioShack every time I visited the Duncan Mall just to see what was new. For you younger people out there, understand that at one point, there were no other options for many of the products you could find at RadioShack. No Best Buy, no Amazon.com or Tiger Direct. Here are 10 of the products that I could only get from RadioShack.To read this article in full or to leave a comment, please click here

SSL Week Means Less Weak SSL

CloudFlare SSL Week

I'm excited to announce that today kicks off SSL Week at CloudFlare. Over the course of this week, we'll make a series of announcements on what we're doing to improve encryption on the Internet.

Inherently, for encryption to be the most effective, it has to meet three criteria: 1) it needs to be easy and inexpensive to use; 2) it needs to be fast so it doesn't tax performance; and 3) it needs to be up to date and ahead of the latest vulnerabilities.

Easy, Fast & Secure

Throughout CloudFlare's history, these priorities have guided our approach to encryption. Last September, we announced Universal SSL and brought world class encryption to every CloudFlare customer, even those on our Free service plan. While that effort doubled the size of the encrypted web, our work is far from done. This week we're announcing a series of initiatives that further our efforts to ensure we provide the easiest, fastest, and most secure encryption.

While Universal SSL made it easy to ensure that the connection from a device to CloudFlare was secure, this week we're going to begin the process of making it easy (and free) to ensure the connection from CloudFlare back to Continue reading

New weapons offer hope against advanced cyber-attacks

One of the most frightening things about modern cyber-attacks is that a breach can remain undetected within networks for weeks, months or even years. This time gives hackers the luxury of lateral movement within a network, meaning they can acquire better credentials, compromise more systems and search for the most profitable and most damaging information. And perimeter defense tools are almost worthless once hackers are quietly rampaging behind the lines. But malware has to communicate back to the hackers somehow, and new monitoring tools have emerged that can identify that traffic. As such, traffic monitoring tools could very well be the next big thing in network security, protecting networks against cyber-attacks and helping even if a breach has already happened.To read this article in full or to leave a comment, please click here(Insider Story)

Lenovo hit with lawsuit over Superfish snafu

Lenovo admitted to pre-loading the Superfish adware on some consumer PCs, and unhappy customers are now dragging the company to court on the matter.A proposed class-action suit was filed late last week against Lenovo and Superfish, which charges both companies with “fraudulent” business practices and of making Lenovo PCs vulnerable to malware and malicious attacks by pre-loading the adware.Plaintiff Jessica Bennett said her laptop was damaged as a result of Superfish, which was called “spyware” in court documents. She also accused Lenovo and Superfish of invading her privacy and making money by studying her Internet browsing habits.The lawsuit was filed after Lenovo admitted to pre-loading Superfish on some consumer PCs. The laptops affected by Superfish include non-ThinkPad models such as G Series, U Series, Y Series, Z Series, S Series, Flex, Miix, Yoga and E Series.To read this article in full or to leave a comment, please click here
