If I had it my way, our house would go off the grid as far as energy needs are concerned. I remember thinking about geothermal heating and cooling with solar panels for electricity generation. There are these fancy battery banks to store energy you get from the sun. When I looked into the costs, I would need a much bigger income than we produce now. So, the dream is big and maybe even noble. However, the realistic application of it is not there. We did, however, go to http://www.energyproviderstexas.com/reliant-energy-texas/ to find an electricity supplier that would give us the lowest monthly rate for electricity in Texas that was possible.
I did not want solar for the ethics of it. I wanted it to be free from the grid. It is part of my self-reliant and self-sufficient personality. It is not about prepping for any survival scenario. Being mobile is useful under those situations anyway. No, my wife and I just like to provide for our own needs as much as possible. We both thought that having a home that was not connected by pipes or wires to the public grid would be nice. So, we have a goal of getting there, but the reality of it is that we do what we can to minimize our reliance on public services.

AMD unveiled a great deal of information at Hot Chips about its upcoming “Zen” CPU core and architecture. The new chip has been the subject of an enormous amount of speculation for more than a year, but things have heated up over the past few weeks as leaked benchmarks surfaced and AMD conducted its own public test.
Today’s information dump is the most detail AMD has shared to date — in fact, it’s significantly more information than I expected the company to share until Zen actually launched. Let’s get started.
Zen’s design goals
Zen is best understood as a response to the problems that plagued Bulldozer. AMD’s original goal with that architecture was to intelligently share resources between CPU cores, while simultaneously hitting higher frequencies and higher execution efficiencies than AMD’s previous CPU core, K10. Bulldozer’s failure to deliver left AMD in an ugly position: Should it try to repair its old core or return to the drawing board and build something completely new?
Sources we’ve spoken to at AMD suggest that the difficulty of repairing Bulldozer was significant enough that AMD opted to build a new core from scratch with none of Bulldozer’s baggage. That doesn’t mean there’s no Bulldozer DNA in Zen — in fact, AMD has stated that the expertise it gained from improving Steamroller and Excavator’s energy efficiency was put to good use for its newest architecture. Say instead that what design elements AMD does borrow from its previous architectures will be the components of the chip that actually worked well rather than the problematic ones that dominated its performance.
Much of what went wrong with Bulldozer was linked to its cache subsystem and overall architecture, so that’s a good place to start diving into Zen. Where Bulldozer used the concept of a CPU module (defined as a pair of cores that shared resources), Zen uses complexes. One CPU complex (CCX) contains four cores, 2MB of L2 cache (512KB per core), and 8MB of L3 cache. That means AMD’s highest-end consumer Zen contains eight cores and 16MB of L3 cache in total, split into 2x8MB chunks. AMD has stated that the two CCXs on an eight-core chip can communicate with each other via the on-chip fabric, though there’s likely a performance penalty for doing so.
Zen’s L3 cache operates as a victim cache for the L1 and L2, meaning data evicted from those caches is stored in the L3 instead. It’s also 16-way associative, which is a significant change from Bulldozer’s 64-way associative L3. A cache with a higher set associativity has a greater likelihood of containing the information the CPU is looking for, but takes longer to search — and one of the issues that crippled Bulldozer was its cache latency at nearly every stage.
We don’t know anything about clock speeds on either the L3 cache or the integrated memory controller. Historically, AMD’s Bulldozer-derived CPUs and APUs have used a clock between 1.8 – 2.2GHz for the L3 cache and IMC.
AMD has stated that L1 and L2 bandwidth is nearly 2x Excavator while L3 bandwidth is supposedly 5x higher. These changes should keep the core fed and support higher performance. The L1 cache is write-back instead of write-through — that’s a significant change that should improve performance and reduce cache contention (Bulldozer’s write-through cache meant that L1 performance could be constrained by L2 cache write speed in some cases).
Buying a computer is a big investment. And with so many different options available, it can be hard to figure out how to meet the technical needs of your nonprofit or library and still stay within your budget.
This guide will help you understand the questions to ask when shopping for a computer. It will also provide a quick reference checklist with definitions of some basic technology terms (not too many!), as well as the minimum standards we recommend for computers.
Things to Consider When Buying a Computer
1. Do You Need a New Computer?
It’s possible some basic maintenance tasks or a simple hardware upgrade can boost performance and give your old computer new life.
2. How Will You Be Using the Computer?
If you do need a new computer, one of the most important things to consider is how you will actually use it.
- A technology plan, technology budget, and technology strategy are all helpful tools to make sure you understand your current and future computing needs. See TechSoup’s Business and Technology Planning section for resources to help you plan effectively.
- What kind of work will your staff be doing? Basic office tasks, like creating documents and spreadsheets, checking email, and using the Internet? Or heavy-duty work with video, audio, or images? Audiovisual work tends to be resource-intensive and will require a more robust computer.
- Will your staff be traveling, or only using the computer in the office?
- How does the computer fit in with your existing technology?
- What operating systems do you use? Operating systems, like Windows, use up a lot of your computer’s resources. If you barely meet the minimum hardware standards for using your operating system, you may not have the computing resources to do a lot of other tasks at the same time (multitask).
- What software do you use? Do you have software that only works with a certain type of computer or only runs on a particular operating system?
- 32-bit and 64-bit? The key thing to know is that hardware and software come in 32-bit and 64-bit versions. If your computer has a 32-bit operating system or hardware, you cannot run 64-bit software on it.
- What are your future plans? Are you planning to upgrade your operating system or add a new kind of software? Are you planning to do different kinds of tasks in the next couple of years?
3. Mac or PC?
The choice between Mac and PC often comes down to personal preference. Both types of computers have their merits. Macs and PCs use the same kinds of internal processors, so they are equally powerful. The main difference between Macs and other computers is the operating system they use: Macs run Mac OS X, and PCs run Windows.
A few things to keep in mind:
- Macintosh computers are usually more expensive off the shelf than a similar PC. However, some argue that the long-term cost for a PC is actually higher, due to additional software and maintenance costs.
- There is some software that will only run on Windows. Make sure the software you depend on is compatible with your new computer’s operating system.
- The more similar your computers are, the easier your technology will be to manage. If you have different types of computers, running different operating systems and different software, troubleshooting and maintenance become much more complicated. Consider whether you already have a Mac- or PC-centric office and whether or not it’s worth switching some or all computers.
4. New, Used, or Refurbished?
If you plan to use the computer for basic office tasks like word processing, email, and web browsing, you probably don’t need a top-of-the-line or brand new computer. A used or refurbished computer may be just fine. Used and refurbished computers are usually much less expensive than new computers. They’re also a greener option, since you’re extending the life of an old computer, rather than buying a brand-new one.
A refurbished computer may be a better option than a used or donated one. Refurbished computers are older machines that have been carefully inspected and updated by professionals. If you get your refurbished computer from an authorized professional refurbisher (and you always should), you will know it is in good working condition. Refurbished computers also often have a warranty of some kind. Read more about refurbished computers available to eligible organizations through TechSoup’s Refurbished Computer Initiative.
There are some additional things you need to think about when buying refurbished equipment:
- Fail and return rates. Check the refurbisher’s fail and return rates.
- Warranty. You probably won’t get a three-year warranty for a refurbished computer, but a three-month warranty is pretty standard. This should cover any out-of-the box problems.
- Peripherals, software, and documentation. Make sure you know what is included with your computer. Refurbished computers, for example, rarely come bundled with a monitor.
If you are buying a used (rather than refurbished) computer, or accepting a donated one, make sure a knowledgeable person inspects the computer thoroughly first. This will help ensure the computer is functioning properly and that it will meet your needs. Remember that as alluring as a free or very cheap computer might seem, an old one in poor condition can actually be more trouble than it is worth.

Hewlett Packard Enterprise Co. will spin off software units in an $8.8-billion deal that it says will help it focus on faster-growing businesses. The Palo Alto, Calif., company said Wednesday that the spun-off software businesses — they include big data, security for big companies and IT operations management units — will merge with British software company Micro Focus International.
Hewlett Packard Enterprise is to get a $2.5-billion cash payment and a 50.1% stake in the combined company. The deal requires antitrust approval and is expected to close in the third quarter. Hewlett-Packard Co. split into two companies last year, with Hewlett Packard Enterprise selling commercial tech products and services, while HP Inc. focuses on personal computers and printers.
The forced brevity that gave Twitter its rapid-fire feel is getting pared back for the second time in as many months. The San Francisco social media company began welcoming videos of up to two minutes, 20 seconds nearly five times the previous limit. In addition, Twitter’s Vine app, which hosts constantly-looping six-second videos, now allows some users to link to longer clips via a “Watch more” banner in the bottom right corner.
Twitter relaxed its 140-character limit on posts by removing links and some other items from the count. After a decade of sticking to the concept that finite space breeds creativity, the company is warming to the idea that people need room to roam.
The changes give high-profile Twitter users more ways to integrate advertising and make money off their posts, company spokeswomen said. But more than that, it gives top users one less reason to divert attention to Facebook, Snapchat and other apps. Users have separate gripes about limits on each service, but none has been as defined by stringency as Twitter.
Twitter finds itself retooling to compete for the attention of celebrities and companies, whose content attracts the masses of lurkers that advertisers want to pitch. Adding new users at a faster pace has been a top goal at Twitter because Wall Street zeroes in on user growth to value social networking companies. Twitter also unveiled Engage, a separate app to help users with large followings track incoming messages and statistics about their posts.
Binghamton University computer science assistant professor Timothy Miller, Aaron Carpenter and graduate student Philip Dexterm, along with co-author Jeff Bush, have developed Nyami, a synthesizable graphics processor unit (GPU) architectural model for general-purpose and graphics-specific workloads. This marks the first time a team has taken an open-source GPU design and run a series of experiments on it to see how different hardware and software configurations would affect the circuit’s performance.
According to Miller, the results will help other scientists make their own GPUs and push computing power to the next level.
“As a researcher, it’s important to have tools for realistically evaluating new ideas that may improve performance, energy efficiency, or other challenges in processor architecture,” Miller said. “While simulators may take shortcuts, an actual synthesizable open source processor can’t cut any corners, so we can say that any experimental results we get are especially reliable.”
GPUs have existed for about 40 years and are typically found on commercial video or graphics cards inside of a computer or gaming console. The specialized circuits have computing power designed to make images appear smoother and more vibrant on a screen. There has recently been a movement to see if the chip can be applied to non-graphical computations such as algorithms processing large chunks of data.
“We weren’t necessarily looking for novelty in the results, so much as we wanted to create a new tool and then show how it could be used,” said Carpenter. “I hope people experiment more effectively on GPUs, as both hobbyists and researchers, creating a more efficient design for future GPUs.”
The open-source GPU that the Binghamton team used for their research was the first of its kind. Although thousands of GPUs are produced each year commercially, this is the first that can be modified by enthusiasts and researchers to get a sense of how changes may affect mainstream chips. Bush, the director of software engineering at Roku, was the lead author on the paper.
“It was bad for the open-source community that GPU manufacturers had all decided to keep their chip specifications secret. That prevented open source developers from writing software that could utilize that hardware,” Miller said. Miller began working on similar projects in 2004, while Bush started working on Nyami in 2010. “This makes it easier for other researchers to conduct experiments of their own, because they don’t have to reinvent the wheel. With contributions from the ‘open hardware’ community, we can incorporate more creative ideas and produce an increasingly better tool.”
The ramifications of the findings could make processors easier for researchers to work with and explore different design tradeoffs. Dexter, Miller, Carpenter and Bush have paved a new road that could lead to discoveries affecting everything from space travel to heart surgery.
“I’ve got a list of paper research ideas we can explore using Nyuzi [the chip has since been renamed], focusing on various performance bottlenecks. The idea is to look for things that make Nyuzi inefficient compared to other GPUs and address those as research problems. We can also use Nyuzi as a platform for conducting research that isn’t GPU-specific, like energy efficiency and reliability,” Miller said.
