Logitech headsets and webcams for the business professional

  • Posted on February 19, 2017 at 10:07 pm

As many of you know, I’m a full-time telecommuter. Although a portion of my work involves some travel, most days I am working from home, and a lot of that involves sitting on conference calls with colleagues and customers/partners.

Until recently, much of that required that I be desk-bound.

Anyone who has to work with VOIP and IP-based conferencing systems such as Skype, Microsoft Lync, Cisco WebEx and Citrix GoToMeeting knows that voice quality is everything if you’re going to have an effective business conversation.

And that means using devices that typically tie you to your desk, such as a wired headset or an Bluetooth/USB speakerphone, such as the Plantronics Callisto, which I have and think is an excellent product.

While there are many Bluetooth headsets and earpieces on the market which are perfectly suitable for mobile phone conversations, few are specifically optimized for use with PCs that have VOIP “Soft Phone” software, and do not deliver what I would regard as business critical voice quality.

They are perfectly fine for short calls, but not ideal when you are on a VOIP conference for as much as an hour at a time, or even longer, particularly when you need to be an active participant and when paying close attention to who is speaking and the clarity of what you are saying is essential.

As we all know about Bluetooth when it comes to audio streams, the farther you get away from the transceiver, the worse the audio gets. So it’s not practical to stray too far away from your PC.

Logitech’s latest wireless headsets have been a total game changer for my personal work situation since I’ve been using them the last few months. I’ve been using the H820e stereo version which retails for $199 but can be found for considerably less.

Installation and use of the headset is pretty straightforward — you plug the DECT 6.0 transmitter and charging base into a free USB port on your PC or Mac, and the AC power cord to power the base. The headset charges on the base when not in use, and has a built-in rechargeable battery.

The operating system recognizes it automatically, and depending on the VOIP program you are using, you may need to alter the settings to use the headset as your primary audio device.

If you’re familiar with the DECT 6.0 1.9Ghz wireless transmission standard, particularly if you have cordless phones in your house that use the technology, you know that you can get some pretty impressive range and not lose any voice quality. That’s exactly what the H820e headset gives you for VOIP calls.

My home office is a good 60 feet away from my living room and around 75 feet from my “breakfast area” which has my espresso machine and a table which faces my outdoor patio and pool area with outdoor furniture which is about 100 feet or so away from the base transmitter.

So regardless of what VOIP software I am using, and where I am in my house, I get the same crystal-clear voice quality as if I am sitting right in front of my PC. For example, this wearable computing podcast that I recorded with Rick Vanover of Veeam was actually done in my living room, while wearing the H820e using Skype.

So the quality of the audio is without dispute. What about the overall design and using it?

Hacking with a Hacker

What is it like to hack with one of the original hackers? It is certainly much different than what Appears to be the modern rendition of hacking. My experience was not getting really drunk with tons of junk food. It was not working on “beautiful” designs or “authentic” typography. It was not so much about sharing with the world as it was sharing with your peers. It had a very different feel to it than the “hacker culture” Promoted by some of the top technical Silicon Valley companies. It felt more “at home”, less dreamy, and more memorable.

I meet with Bill Gosper every so Often; I had the pleasure of giving him a tour of Facebook when I worked there. (He was so surprised that they had Coke in the glass bottles there, just like the old days.)

He is still very much a hacker, a thinker, a tinkerer, and a wonderer. Every time I meet up with him, he has a new puzzle for me, or someone around him, to solve, whether it’s really clever compass constructions, circle packing, block building, Game of Life automata solving, or even something more tangible like a Buttonhole homemade trap (which was affixed to my shirt for no less than two weeks!). He is also the bearer of interesting items, such as a belt buckle he gave me roomates depicts, in aluminum, a particular circle loose packing.
Gosper succeeding in tricking me with the Buttonhole Trap
When we meet up, all we do is hack. Along with him and one of his talented young students, we all work on something. Anything interesting, really. Last time we met up, we resurrected an old Lisp machine and did some software archeology. I brought over some of the manuals I own, like the great Chinual, and he brought over a dusty old 1U rackmount Alpha machine with OpenGenera installed. After passing a combination of Hurdles, such as that the keyboard was not interfacing with the computer Correctly, we finally got it to boot up. Now, I got to see with my own eyes, a time capsule containing a lot of Bill’s work from the 70s, 80s, and 90s, roomates could only be commanded and Examined through Zmacs dired and Symbolics Common Lisp. Our next goal was to get Symbolics Macsyma fired up on the old machine.

There was trouble with starting it up. License issues were one problem, finding and loading all of the files were compiled another. Running applications on a Lisp machine is very different than what we do today on modern machines, Windows or UNIX. There’s no. Exe file to click, or. App bundle to start up, or even a single. / File to execute. Usually it’s a collection of compiled “fast loading” or “fasl” files that get loaded side-by-side with the operating system. The application, in essence, Becomes a part of the OS.

In hacker tradition, we were Able to bypass the license issues by modifying the binary directly in Lisp. Fortunately, such as Lisp makes things easy disassembly. But how do we load the damn thing? Bill frustratingly muttered, “It’s been at least 20 years since I’ve done it. I just do not remember. “I, being an owner of MacIvory Symbolics Lisp machines, fortunately did remember how to load programs. “Bill, how about LOAD

TSP Symposium 2013 Keynotes to Focus on Quality Practices for Critical Software

  • Posted on February 16, 2017 at 3:25 pm

The Carnegie Mellon University Software Engineering Institute (SEI) has announced the slate of software engineering thought-leaders who will serve as keynote speakers for the Team Software Process (TSP) Symposium 2013. Held in Dallas, Texas, on September 16-19, the TSP Symposium 2013 keynote line-up includes Bill Curtis, senior vice president and chief scientist with Cast Software; Enrique Ibarra, senior vice president of technology of the Mexican Stock Exchange (BMV); and Robert Behler, chief operating officer of the SEI.

The symposium theme, When Software Really Matters, explores the idea that when product quality is critical, high-quality practices are the best way to achieve it.

“When a software system absolutely must work correctly, quality must be built in from the start. A disciplined approach to quality also offers the benefit of lower lifecycle costs. The TSP promotes the application of practices that lead to superior, high-quality products,” said James McHale, TSP Symposium 2013 technical chair. “Our keynote speakers and representatives from industry and government organizations from around the world will share how using TSP helps organizations build quality in from the start when there’s no room for error.”

  • Curtis will assert that the stakes for software-caused operational problems are now larger than ever, approaching a half-billion dollars per incident. Every other aspect of the business is managed by numbers, including IT operations. Software lags behind, however, because the culture of craftsmanship still prevails. Curtis’s talk will challenge that culture: Quality measurement will be challenged for under-measuring non-functional, structural quality, the cause of many operational disasters. Productivity measurement will be challenged for not penalizing baselines when rework is shifted into future releases as technical debt. Software measurement will be challenged to better express outcomes in terms that justify investments for improving quality. The word “quality” will be challenged as the wrong way to frame the argument. Curtis will propose a measurement stack or measurement pyramid to help translate software numbers to business numbers. At the foundation of this pyramid are the Personal Software Process (PSP) and TSP.
  • Ibarra will detail the Mexican Stock Exchange’s (BMV) broad plan of technological renovation that included migration to a new state-of-the-art data center and creating new operational systems with better functionalities and quality attributes. Since 2005, the BMV, which is responsible for operating the cash and derivatives market of the country and is the only exchange in Mexico, has faced the constant challenge of accommodating an exponential growth of demand for its transactional services as well as pressure from the market to offer services with better response times and functionalities. One of the most challenging software projects included in this technological renovation plan was the redesign and construction of the operational system known as the trading engine, which has strict and ambitious requirements for speed (latency), scalability, and continuous availability. The new system, which was to be designed and built internally, and the project were called MoNeT. The BMV had two goals for MoNeT: making sure a carefully considered and reviewed system architecture was in place prior to building the system and adopting a software development process that maximizes the quality of the new system and ensures that it complies with its intended quality attributes. Ibarra will describe the most relevant aspects of the MoNeT project, its performance in production, and the business impact it had on the BMV.
  • Behler, one of only 139 individuals qualified as pilots of the Lockheed SR-71 Blackbird aircraft, will describe his experience flying the fastest,

Acer Aspire V5-122 with AMD Temash

Jakarta-ultrabook exorbitant price makes it less attractive thin notebook. Despite having a number of advantages compared to notebooks in general, such as fast boot time and lightweight body, the average price is above USD 10 million to be a serious obstacle.

As an alternative, some computer vendors began marketing sense ultrabook notebook with a more affordable price. Call it VivoBook X202E Asus, Lenovo IdeaPad Yoga 11, Dell XPS 12, or Acer Aspire V5-122.

Yes, with many excellent features adopted from the ultrabook, notebook sold in the under $ 10 million. But in terms of performance is less than the true ultrabook. But the experience of computing an ultrabook can still be felt on the notebook.

In the past week, Tempo had tried Acer Aspire V5-122. Body is lightweight and thin making the Aspire V5 easily incorporated into the bag and convenient to carry anywhere. Interestingly, in the Aspire V5-122 grafted Temash low-power AMD processors.

DESIGN

Thin, lightweight, and stylish. That first impression when touched obtained Tempo Acer Aspire V5-122. Body wrapped in metallic silver color adds an elegant notebook with a 11.6-inch wide screen. While at the bottom, cover plastic dark black plated.

Every corner of the Aspire V5-122 made rounded. While the keyboard on the inside of the black chiclet design. Fairly wide spacing between the keys making it comfortable to use for fast typing.

Touch pad size is not too big, but it’s not a problem. Therefore, Aspire V5-122 is equipped with a touch screen that is able to respond to ten touch points. The touch screen was optimal when used with the Windows 8 operating system from Microsoft.

Like ultrabook, Aspire V5-122 also brought the concept of unibodi. That is, the types of Li-ion battery 3-cell it carries can not be removed. But you do not need to worry because Acer ensure the battery life is long enough.

Connectivity

Like most new output notebooks, Aspire V5-122 is equipped with the latest features for connectivity. One of which is USB 3.0 is capable of transferring and receiving data 10 times faster than USB 2.0. USB 3.0 port is located on the left side.

In addition to USB 3.0, Aspire V5-122 is equipped with a USB 2.0 port is on the right side. In addition there is a card reader slot. As for the wireless connectivity, Acer presents Wi-Fi 802.11 b / g / n and Bluetooth 4.0.

SCREEN

Screen Aspire V5-122 is able to produce high levels of brightness. Using glossy reflective technology, the Aspire V5-122 black color makes it look more dense and the resulting image sharpness deeper than the regular screen.

Only, with a relatively cheap price than the ultrabook, Acer just immerse the display with a standard resolution, 1,366 x 768 pixels only. That is, watch the video with 1080p high definition resolution was less than optimal on-screen Aspire V5-122’s.

Moreover, with the use of the Windows 8 operating system and the increasing number of applications that require content HD screen resolution, screen technology Aspire V5-122 feels a little left behind.

PERFORMANCE

Acer Aspire V5-122 is equipped with AMD processors Jaguar Temash APU A6-1450 quad-core processors with speeds up to 1 GHz of computing processes. As for the graphics processing embedded AMD Radeon HD 8280G which has a thermal design power (TDP), only 8 watts.

Jaguar AMD A6-1450 APU processor is the new output. This low-power processor platform is the successor of Zacate
