The XPRT Women Code-a-Thon

on January 28, 2016

As Justin explained last week, we’ve resolved the issue we found with the TouchXPRT CP. I’m happy to say that the testing went well and that we released CP3 this week.

It’s been only three weeks since we announced the XPRT Weekly Tech Spotlight, and we already have another big announcement! Principled Technologies has joined with ChickTech Seattle to host the first ever XPRT Women Code-a-Thon! In this two-day event, participants will compete to create the best new candidate workload for WebXPRT or MobileXPRT. The workloads can’t duplicate existing workloads, so we are looking forward to seeing the new ideas.

Judges will study all the workloads and award prizes to the top three: $2,500 for first place, $1,500 for second place, and $1,000 for third place. Anyone interested can register here.

PT and the BenchmarkXPRT Development Community are committed to promoting the advancement of women in STEM, but we also win by doing good. As with the NCSU senior project, the BenchmarkXPRT Development Community will get some fresh perspectives and some new experimental test tools. Everyone wins!

So much has happened in 2016 and January isn’t even over yet. The year is off to a great start!

In the spotlight

By Eric Hale

on January 14, 2016

I’m happy to be back in North Carolina, but I had a really great time at CES. I talked to over a dozen companies about the XPRTs and the XPRT Weekly Tech Spotlight, and had some good conversations. Hopefully, some of these companies’ devices will be among the first ones we showcase when the XPRT Weekly Tech Spotlight goes live next month.

Of course, I saw some really great tech at CES! Amazing TVs and cars, magic mirrors, all kinds of drones, and the list goes on. Before the show, the Internet of Things was predicted to be big this year, and boy, was it! Smart refrigerators, door locks, and thermostats were just the beginning. Some of my favorite examples were the chopsticks and footbath—both Bluetooth enabled—and “the world’s first remote controlled game shoe.”

Clearly IoT is the Wild West of technology right now. We’re had some conversations about how the XPRTs might be able to help consumers navigate the chaos. However, with a class of products this diverse, there are a lot of issues to consider. If you have any thoughts about this, let us know!

Auf Deutsche

Early next week, we will update WebXPRT by adding a German UI. This brings the number of available languages to three. WebXPRT has had a Simplified Chinese UI for a while, but you had to click a link on the WebXPRT page to get it. The new version removes that limitation, and lets you select Simplified Chinese, English, or German from the UI.

We’re working on getting WebXPRT to automatically detect the language of your device, but for now, the UI defaults to English.

We would like to expand the range of languages the XPRTs support over time. This is an area where you can help. If you’d like to see your language represented and are willing to help with translation, please let us know.

I know it’s the holiday season, but remember that CES will be here before we know it. I’m really looking forward to seeing the show, and I may have some big news to talk about while I’m there! If you’re planning to be at CES, send a message and let’s find a time to meet!

We will not have a blog post next week. Happy holidays!

Eric

Last week in the XPRTs
We published the December 2015 BenchmarkXPRT Development Community newsletter.
We added one new BatteryXPRT ’14 result.
We added nine new MobileXPRT ’13 results.
We added one new MobileXPRT ’15 result.
We added four new WebXPRT ’15 results.

Question we get a lot

By Eric Hale

on October 2, 2015

“How come your benchmark ranks devices differently than [insert other benchmark here]?” It’s a fair question, and the reason is that each benchmark has its own emphasis and tests different things. When you think about it, it would be unusual if all benchmarks did agree.

To illustrate the phenomenon, consider this excerpt from a recent browser shootout in VentureBeat:

While this looks very confusing, the simple explanation is that the different benchmarks are testing different things. To begin with, SunSpider, Octane, JetStream, PeaceKeeper, and Kraken all measure JavaScript performance. Oort Online measures WebGL performance. WebXPRT measures both JavaScript and HTML 5 performance. HTML5Test measures HTML5 compliance.

Even with benchmarks that test the same aspect of browser performance, the tests differ. Kraken and SunSpider both test the speed of JavaScript math, string, and graphics operations in isolation, but run different sets of tests to do so. PeaceKeeper profiles the JavaScript from sites such as YouTube and FaceBook.

WebXPRT, like the other XPRTs, uses scenarios that model the types of work people do with their devices.

It’s no surprise that the order changes depending on which aspect of the Web experience you emphasize, in much the same way that the most fuel-efficient cars might not be the ones with the best acceleration.

This is a bigger topic than we can deal with in a single blog post, and we’ll examine it more in the future.

Upping our game

By Eric Hale

on August 27, 2015

As we wrote last week, we’re releasing MobileXPRT 2015 to the public tomorrow. Thanks to everyone who helped make the community preview a success!

We’re working on the TouchXPRT 2016 design document and will make it available for the community to review soon.

As you know, we’re always investigating initiatives that could improve our game. We’re continuing to investigate creating experimental tests for future XPRTs. Experimental tests will allow us to maintain broad compatibility for each XPRT tool while providing testers with an opportunity to evaluate cutting-edge technologies.

Another initiative involves looking for new partnerships with people who are not yet part of the community, but could add valuable input to the development process. It’s too soon to say much more about this, but we’re having fruitful conversations and hoping that these partnerships will grow the community even more!

If you have ideas about experimental tests, improving the XPRTs, or expanding the community, please let us know.

Explaining the BenchmarkXPRT Development Community

By Bill Catchings

on August 6, 2015

Over the last year, I’ve spoken about the XPRT benchmarks with people across America, in China (at IDF Shenzhen), and in Europe (at Mobile World Congress). I regularly found myself having to explain how the BenchmarkXPRT Development Community works. While I was glad to do so, I found myself wishing that the many people I wasn’t able to talk with could also learn about how the community works.

To help make that happen, we’ve developed a simple and engaging video. My (admittedly prejudiced) opinion is that it does a great job of explaining how the community works in less than two minutes. That’s a lot faster than I was able to explain it to folks!

We hope you enjoy the video. And we hope you’ll pass it along to other folks who aren’t already part of the community so they can learn how it works and hopefully be persuaded to join us. Thanks!
