Twitter algorithm changes will hide more bad tweets and trolls

Twitter latest effort to curb trolling and abuse on the site takes some of the burden off users and places it on the companyalgorithms.

If you tap on a Twitter or real-world celebritytweet, more often than not therea bot as one of the first replies. This has been an issue for so long ita bit ridiculous, but it all has to do with the fact that Twitter really only arranges tweets by quality inside search results and in back-and-forth conversations.

Twitter is making some new changes that calls on how the collective Twitterverse is responding to tweets to influence how often people see them. With these upcoming changes, tweets in conversations and search will be ranked based on a greater variety of data that takes into account things like the number of accounts registered to that user, whether that tweet prompted people to block the accounts and the IP address.

Tweets that are determined to most likely be bad aren&t just automatically deleted, but they&ll get cast down into the &Show more replies& section where fewer eyes will encounter them.The welcome change is likely to cut down on tweets that you don&t want to see in your timeline. Twitter saysthat abuse reports were down 8 percent in conversations where this feature was being tested.

Much like your average unfiltered commenting platform, Twitter abuse problems have seemed to slowly devolve. On one hand itbeen upsetting to users who have been personally targeted, on the other hand itjust taken away the utility of poring through the conversations that Twitter enables in the first place.

Itcertainly been a tough problem to solve, but they&ve understandably seemed reluctant to build out changes that take down tweets without a user report and a human review. This is, however, a very 2014 way to look at content moderation and I think itgrown pretty apparent as of late that Twitter needs to lean on its algorithmic intelligence to solve this rather than putting the burden entirely on users hitting the report button.

Last November, AWS announceda new product called Amazon Sumerian, a toolkit and platform for developers to build &mixed reality& apps — that is, using virtual reality, augmented reality and 3D — without needing to have any specialised programming or graphics skills. And today, after running the service in a private beta for the last several months, Sumerian is now generally available.

In addition to being able to build a mixed reality app, you can also deploy it without writing custom code, Amazon says. The web-based editor also integrates with AmazonLexfor natural language and AI,Pollyto turn text into speech,AWS Lambdafor running code, AWS IoTto connect with AmazonIoT platform, andAmazonDynamoDBif you are running a NoSQL database. It supportsWebGLandWebVRandOculus Rift,HTC Vive, iOS and AndroidARCore. Support for the newOculus Gois coming, AWS said.

AWS has made huge strides in building out its cloud business, where developers, startups and much larger and mature organizations use the companyinfrastructure to host apps and other services, in what looks to be on track to be a $20 billion business this year. More recently, Amazon has been looking at ways of expanding its reach (and revenues) with these companies by offering a deeper range of services running within the cloud. Amazon Sumerian is a part of that strategy.

As Kyle Roche, the GM of Amazon Sumerian, described it, the company saw a gap in the market between the rise of new VR, AR and 3D tech, and a huge pool of organizations that might want to use that technology, but either lack the expertise and resources to do so, or would like to test something out before dedicating those resources more seriously.

&We are targeting enterprises who don&t have the talent in-house,& he said. Tackling new tech can sometimes be &too overwhelming, and this is one way of getting inspiration or prototypes going. Sumerian is a stable way to bootstrap ideas and start conversations.There is a huge business opportunity here.&

He said that early users in the closed beta have included a company developing training for medical devices, Mapbox building a framework for geospatial rendering, a business designing a walk-through a hotel lobby, e-sports companies, and some media and entertainment properties.

AdamSchouela, the VP of Fidelity Labs, said that the financial services giant has been working on a range of potential applications, including solutions to train its customer relations teams, ways of visualising financial modelling, and services for its customers to discover and use Fidelityservices.

&What we try to do is look at emerging tech and rapidly build prototypes for Fidelity and the financial services industry,& he told TechCrunch. We&ve done a lot of work in the voice interfaces and user interfaces with AR and VR. When we saw what Sumerian was providing and potential integration between voice interfaces and VR, we thought this was a great opportunity. With voice interfaces one of the great use cases is when your eyes and hands are otherwise busy. With VR, itstuck to face and you can&t see and your hands are busy so voice happens to be a great way of interacting with virtual environments.&

A demo of one of Fidelityservices is here:

I/O may have ended, but Googlestill trickling out news at a steady rate. The latest update comes from one of the more unexpected corners of the Googleverse. Pixel Buds, the companyhotly anticipated and lukewarmly received bluetooth headphones are getting a nice software update.

In a blog post today, the company highlighted some new features that should help make the earbuds a bit more well-rounded.

At the top of the list is improved bluetooth pairing. Itnot a hardware upgrade, so users may still run into some of the issues the product got dinged for early on, but not ita lot easier to switch between synced hardware. Choosing Pixel Buds from the drop down menu on a connected computer will swap the connection from the current to new device.

GooglePixel Buds learn some new tricks

The headphones are also getting a couple new touch gestures. Triple tapping the right earbud will turn the headphones on and off, while double tapping will skip a song to the next track. Though that second gesture requires going into the Pixel Buds settings inside the Google Assistant app to enable.

All of those updates are rolling out to users starting today. None are earth shattering, exactly, but they should make the Pixel Buds experience a bit better for those who&ve already plunked down the $160 for Googlewireless headphones.

Blogger gets a spring cleaning

Blogger, the blogging platform Google acquired back in 2003, is somehow still alive and kicking, even though few people remember it still exists. But alive it is — and iteven getting some updates to its Google+ integration that will see all those 20 people still on Google+ rejoice.

After a year of inactivity, Blogger own news blog sprung to live this morning with a brief update that lays out the changes. Google calls this a &spring cleaning,& and we all know what that means: shutting down features.

You probably don&t care, but gone from Blogger are support for third-party gadgets, the Next Blog feature and the polling widget. Soon, OpenID support will be gone, as well, and Textcube.com is also shutting down. What is Textcube.com, you ask Ita Korean blogging service Google acquired back in 2008.

But there are also new features, which I&m guessing the sole two engineers still working on this project slaved over for the last year.

BloggerGoogle+ widget integration (yes, try not to laugh) will be transformed into HTML widgets to &give you more flexibility in how you share and see your followers.& Fifteen years after acquiring the service, Blogger now also supports logging in with multiple accounts. Google also today noted that the Blogger infrastructure has moved to Cloud Spanner, Googlenewest database service.

In the near future, you can expect a new video management feature, too. Exciting stuff.

Itsurprising that Blogger is still around. I can&t remember the last time I saw a Blogger site in my searches, and it sure doesn&t have a lot of mindshare. Google also has let the platform linger and hasn&t integrated it with any of its newer services. The same thing could be said for Google+, too, of course. Google cuts some services because they have no users and no traction. That could surely be said for Blogger and Google+, but here they are, still getting periodic updates. I think the writing is on the wall, though, and I wouldn&t expect them to survive the next major Google spring cleaning.

Canal+ gives up on its cable box, switches to Apple TV

French premium cable television company Canal+ is slowly moving away from building its own set top boxes. As Next INpact spotted, you can now subscribe to Canal+ and get an Apple TV 4K with Canal+myCanal app already preloaded.

Canal+ has been around for decades and was the first premium TV channel in France. Over the years, the company started distributing all sorts of premium channels through satellite, cable and partnerships with internet service providers.

While you had to get your own Canal+ set top box to receive Canal+ 15 years ago, the companyown box has slowly become irrelevant. As all the main French internet service providers give you a set top box, Canal+ has partnered with them to offer multiple add-ons to receive Canal+content.

When Canal+ announced its most recent device, Canal+ already said that you&d get a better experience with the myCanal app on the Apple TV.

Thatwhy Canal+ is betting everything on over-the-top distribution. If you don&t subscribe to Canal+ through your ISP, you can get an Apple TV 4K for €6 per month in addition to your TV package. If your internet connection isn&t fast enough or you&d rather use satellite TV, you can still get a Canal+ set top box.

But the writing is on the wall. Most people will soon watch Canal+ through myCanal on Android TV, tvOS, iOS, Android, a Samsung TV and desktop computers.

In France, Molotov and myCanal have been some of the top performing apps for tvOS and Android TV. This partnership could boost the Apple TV in France.

Sarah Guo breaks through at Greylock, becoming one of the first female general partners in the firm53-year history

Sarah Guo didn&t necessarily set out to become a venture capitalist. She certainly didn&t imagine she would become one of the first general partners at one of the oldest venture firms in the country. Yet Guo is both of these things today. Indeed, the venture firm Greylock Partners, which Guo joined five years ago as a principal, is announcing her promotion this morning.

Greylock, which closed its current, 15th, fund with $1 billion in October 2016, now has 12 general partners altogether.

For Guo, the appointment caps a lifetime spent in the world of startups. Before joining Greylock, she worked as an analyst at Goldman Sachs, where she led much of the bankcoverage of business-to-business tech companies and advised public clients, including Twitter, Netflix, Zynga, and Nvidia.

A graduate (for both her undergraduate degree and MBA) of the University of Pennsylvania, Guo also worked previously at Casa Systems, a 15-year-old tech company that develops asoftware-centric networking platform for cable and mobile service providers and that — in a twist that we think is pretty neat — was founded by her parents. (Her father, CEO Jerry Guo, took the companypublic earlier this year.)

In a conversation earlier this week, Guo said that growing up around entrepreneurship gave her an &understanding of how difficult& starting a company truly is. It also occurred to her early on that &something related to company building was what I wanted to do in the future.&

Guo also said that not much will change with her promotion. Broadly speaking, she focuses on B2B applications and infrastructure, cybersecurity, AI, AR, and healthcare. She already sits on the boards of several companies, including the security startup Obsidian, which was founded by ex-Cylance and Carbon Black execs last year and quickly raised $9.5 million led by Greylock.

She said she does hope to mentor more up-and-coming investors like herself, however.

Guo first became acquainted with Greylock through Aneel Bhusri, a partner at Greylock and the cofounder and CEO of the software giant Workday. The two talked occasionally when Guo was covering internet and software startups at Goldman, and he&d encouraged her to meet some of his venture partners, she said. &I came in, not necessarily ready to be in venture forever. But I&m now very excited about it obviously,& she added with a laugh.

Guoother deals to date include Aware Networks, a 15-year-old, Buffalo Grove, Il.-based company thatdevelops collaboration applications for mobile communities, and a still-unannounced company.

We didn&t talk about the fact that Guo just became one of Greylockfirst female general partners, but itvery much worth mentioning, considering the firm was founded in 1965.

Greylock had lost another senior female investor — Sarah Tavel — to Benchmark last year. Tavel was the first female general partner at Greylock; she went on to become Benchmark&sfirst female GP.

Altogether, women still represent just 15 percent of decision makers at Silicon Valleymajor venture capital firms. Their ranks are growing slowly however.

Meanwhile, many other investors are choosing to launch their own female-founded venture firms. Among the newest of these is Breakout Ventures and a fund we reported on last night thatbeing created by life sciences investor Beth Seidenberg, long of Kleiner Perkins.

Correction: This story briefly mischaracterized Guo as Greylockfirst female GP. Based on the nomenclature used by Greylock, we were under the impression that Tavel was a partner but not a general partner — a seemingly small but important distinction within venture firms. Tavel had been hired at the GP level at Greylock, we&re told.
