The immortal myths about online abuse • Medium

Anil Dash points out a number of (proven) falsehoods about how to fix abuse within networks, and concludes:

»The bottom line, as I wrote half a decade ago, is that if your website is full of assholes, it’s your fault. Same goes for your apps. We are accountable for the communities we create, and if we want to take credit for the magical moments that happen when people connect with each other online, then we have to take responsibility for the negative experiences that we enable.

Our communities are defined by the worst things that we permit to happen. What we allow tells the world who we are.

«

That “worst things that we permit to happen” is where Twitter is struggling to bring things back to where it wants to be.

Google is working on a new operating system named Fuchsia • The Verge

James Vincent:

»Looking into Fuchsia’s code points gives us a few clues. For example, the OS is built on Magenta, a “medium-sized microkernel” that is itself based on a project called LittleKernel, which is designed to be used in embedded systems (computers that have a specialized function and often don’t need an actual operating system, like the software in a digital watch). Similarly, both of the developers listed on Fuchsia’s GitHub page — Christopher Anderson and Brian Swetland — are experts in embedded systems. Swetland is a senior software engineer at Google and Anderson has previously worked on the company’s Android TV and Nexus Q projects.

However, the Magenta kernel can do a lot more than just power a router. Google’s own documentation says the software “targets modern phones and modern personal computers” that use “fast processors” and “non-trivial amounts of RAM.” It notes that Magenta supports a number of advanced features, including user modes and a “capability-based security model.” Further evidence that Fuchsia is intended for more than just Wi-Fi-connected gadgets include the fact that Google already has its own IoT platform (the Android-based Brillo), and the fact that the new OS includes support for graphics rendering. Some users of Hacker News have even suggested that Fuchsia could be use for augmented reality interfaces.

This story neatly encapsulates a lot of modern (tech) journalism. What’s missing from it? First, it’s a rewrite of an Android Police story. But it adds nothing to it – no outside expert opinion, and particularly no comment from Google itself.
Could nobody pick up a phone and just ask? Even to get “no comment”?

(James Vincent tells me he did contact Google, which hasn’t so far responded. That’s not atypical for Google.)

The Verge often seems to preen about its web presence, but its editors seem content to have lots of warmed-over takes which add nothing to the original. That’s not sustainable for the writers or editors.

Boffins’ blur-busting face recognition can ID you with one bad photo • The Register

Darren Pauli:

»Scientists have found a way to accurately identify completely obscured faces using recognition systems trained on only a handful of well-lit photos.

The work by Seong Joon Oh, Rodrigo Benenson, Mario Fritz, and Bernt Schiele of Max Planck Institute in Saarbrücken, Germany, finds faces can be recognised with up to 91.5% accuracy when the system is fed with just 10 clear images of a target’s face.

The Faceless Person Recogniser is up to 69.6% accurate when working from just one image.

Accuracy sharply falls when imperfect training images are used. The team introduced black colour into the images dropping performance to 14.7%, still better than random guessing which clocks in at 4.65%.

They warn such an accurate system would likely be already in use.

“It is very probable that undisclosed systems similar to the ones described here already operate online,” the team says.

“We believe it is the responsibility of the computer vision community to quantify, and disseminate the privacy implications of the images users share online.”

The paper Faceless Person Recognition; Privacy Implications in Social Media [PDF] finds that obfuscation methods including Gaussian blurring are not enough to prevent obscured photos from being used in facial recognition.

Caution flags for tech in classrooms • NPR

Anya Kamenetz:

»A group of recent studies on technology in education, across a wide range of real-world settings, have come up far short of a ringing endorsement.

The studies include research on K-12 schools and higher ed, both blended learning and online, and show results ranging from mixed to negative. A deeper look into these reports gives a sense that, even as computers become ubiquitous in classrooms, there’s a lot we still don’t know — or at least that we’re not doing to make them effective tools for learning.

First, a quick overview of the studies and their results:

Last fall, the Organization for Economic Co-operation and Development published its first-ever, and one of the largest-ever, international analyses of student access to computers and how that relates to student learning. (The OECD administers the PISA test, the world-famous international academic ranking.)

For this report, the researchers asked millions of high school students in dozens of countries about their access to computers both in the classroom and at home, and compared their answers to scores on the 2012 PISA. Here’s the money quote:

“Students who use computers very frequently at school do a lot worse in most learning outcomes, even after controlling for social background and student demographics.”

«

Are we going to have to rethink this whole thing? Though there is a lot of uncertainty around how computers are used in the different countries, and how those fit into the courses.

How we killed the Tea Party • POLITICO Magazine

Paul Jossey:

»The Tea Party movement began building in the George W. Bush years. Profligate spending and foreign adventurism with no discernible results nurtured disgust with Washington’s habit of spending beyond its means and sending others to die in its wars. When President Obama made reorganizing the nation’s health care system his foremost priority—and repeatedly misrepresented its effects in the process—anger at Washington exploded.

Republicans inside the Beltway reacted to the burgeoning Tea Party with glee but uncertainty about how to channel the grass-roots energy usually reserved for the left. A small group of supposedly conservative lawyers and consultants saw something different: dollar signs. The PACs found anger at the Republican Party sells very well. The campaigns they ran would be headlined “Boot John Boehner,” or “Drop a Truth Bomb on Kevin McCarthy.” And after Boehner was in fact booted and McCarthy bombed in his bid to succeed him, it was naturally time to “Fire Paul Ryan.” The selling is always urgent: “Stop what you’re doing” “This can’t wait.”

One active solicitor is the Tea Party Leadership Fund, which received $6.7m from 2013 to mid-2015, overwhelmingly from small donors. A typical solicitation from the TPLF read: “Your immediate contribution could be the most important financial investment you will make to help return America to greatness.” But, according to an investigation by POLITICO, 87% of that “investment” went to overhead; only $910,000 of the $6.7m raised was used to support political candidates. If the prospect signs a “petition,” typically a solicitation of his or her personal information is recorded and a new screen immediately appears asking for money. Vendors pass the information around in “list swaps” and “revenue shares” ad infinitum.

«

Sounds like the direct marketing/ad tech business, because essentially that’s what it is – just applied to politics. Trump is essentially the politician raking over the furious ashes of the Tea Party’s animus.

Brain.fm brings musical AI to Rio Olympics’ training • ReadWrite

Cate Lawrence:

»Brain.fm is a freemium auditory program designed to help people either focus, relax or sleep using AI-generated music. It’s [sic – CA] users include students, insomniacs and athletes. Heavily steeped in scientific research, its creators have a history in making niche audio brainwave software for psychologists and researchers and their work includes patents on auditory brainwave stimulation and memory.

«

Stumbling over to Brain.fm, one notes that its readme says you shouldn’t use it if you’re epileptic, pregnant, or wearing a pacemaker: “those who fit into any of the above categories, whether knowingly or not, should not use this application.” How can you agree to something you might not know about? (Pacemaker excepted.)

You get a number of free sessions, and then you have to pay. Would like to know if this really has value; Lawrence’s byline photo doesn’t exactly inspire confidence. You’ll see.

Google’s high-speed web plans hit snags • WSJ

Jack Nicas:

»Google parent Alphabet Inc. is rethinking its high-speed internet business after initial rollouts proved more expensive and time consuming than anticipated, a stark contrast to the fanfare that greeted its launch six years ago.

Alphabet’s internet provider, Google Fiber, has spent hundreds of millions dollars digging up streets and laying fiber-optic cables in a handful of cities to offer web connections roughly 30 times faster than the U.S. average.

Now the company is hoping to use wireless technology to connect homes, rather than cables, in about a dozen new metro areas, including Los Angeles, Chicago and Dallas, according to people familiar with the company’s plans. As a result Alphabet has suspended projects in San Jose in California, and Portland in Oregon.

Meanwhile, the company is trying to cut costs and accelerate its expansion elsewhere by leasing existing fiber or asking cities or power companies to build the networks instead of building its own…

…Alphabet hopes the investment in Google Fiber will eventually pay off with subscriber fees and, indirectly, more clicks on its search ads. Fiber costs $70 a month for the fastest internet connection and an additional $60 a month for TV. Analysts estimate a one-time cost for Alphabet of more than $500 for each home the network reaches, not all of which subscribe.

Alphabet declined to disclose its number of subscribers. Based on numbers reported to the U.S. Copyright Office, research firm MoffettNathanson said in March the TV service had 53,000 subscribers total as of December.

«

Based on 53,000 subscribers, that’s revenue of between $11.1m and $20.7m per quarter. Digging up roads really is not such a great business. Setting up wireless internet will be a lot cheaper – but it’s tricky to keep working well: all you need is one big storm and all your carefully placed aerials are out of alignment.

Top three China smartphone vendors had combined 47% market share in 2016 Q2 • IDC

»

iCharts

With growth coming mainly from replacement users in PRC, vendors employed aggressive marketing in the past few months. OPPO hired a few brand ambassadors to launch its R9 series prompting other vendors to follow suit after seeing their strong success. vivo hired a famous Korean star who’s wildly popular in China as its brand ambassador while Xiaomi hired three different ambassadors for its Redmi line. Recently, Huawei also announced a brand ambassador for its Honor line in China – a departure from its previous marketing message focused on product features. Most of these ambassadors seem to target the younger crowd. While having brand ambassadors is not a new phenomenon in China, vendors seem to be more aggressive with their marketing strategies. This is seen to be a new tactic for vendors such as Xiaomi that never used to spend on advertising.

While the Chinese vendors all saw QoQ growth in the market, Apple continued to decline in its shipment volumes. The iPhone SE was not a hit in China, where consumers prefer larger screen-sized phones. In 2016Q2, close to 90% of phones shipped in China had screen sizes that were 5 inches and above. Apple fans are holding out for the new iPhones to be launched in 2016Q3, which could likely give Apple a boost in China.

“In the past, Xiaomi started the trend of selling its phones online and other vendors soon followed suit and created their own online brand. After vendors witnessed OPPO’s success with its R9, they also started riding on the trend of hiring celebrity endorsers to represent their brand and appeal more to the young crowd,” says Xiaohan Tay, senior market analyst IDC Asia/Pacific.

Despite the market being saturated and driven mainly by replacement users, vendors are still aggressive with their marketing tactics, experimenting with new ways to win over consumers.

“Hiring celebrity endorsers may help increase numbers in the short-term, but this alone may not be sufficient to drive numbers in the long run. As there is very little differentiation across products to warrant significant brand loyalty, vendors must constantly think out of the box to get people hyped up about their products,” ends Tay.
