Google: Here’s why dark mode massively extends your OLED phone’s battery life

Published

on

Google’s Android Dev Summit zeroed in on “the cost of a pixel color” yesterday where it revealed how much various colors in apps tax a battery.

While it’s well known that screen brightness uses up more power on LCD screens, Google has been analyzing how different colors impact the battery on OLED screen devices, like the Pixel 3 and the iPhone XS.

Black on OLED screens is known to use less power because the LEDs that make up each pixel are off, whereas displaying white means the LEDs need to shine and consume power.

As Google presenter Chris Banes noted, the screen itself is one of the biggest drains on battery, so the company has been looking at ways developers could minimize the screen’s power usage.

Google Maps in night mode caused the display’s power usage to fall by 63 percent compared with normal mode. Night mode didn’t use any less power on an iPhone 7 with an LCD screen.

Google drilled down further into how different colors impacted power usage. While black uses the least power and white uses the most, Google found that blue used 25 percent more power than green or red.

The company also admitted that it’s been leading developers down the wrong path with Material Design, which encourages developers to use bright colors and lot of white.

“Guess which color we’ve been pushing you to towards over the past couple of years? Material came about three years ago. We changed from Holo, which is a nice dark theme, to a white theme instead. We kind of shot ourselves in the foot slightly in terms of power,” Banes said.

While many of Google’s apps are heavy on white, some apps like YouTube do feature dark mode and as demonstrated, its use can significantly cut the amount power a display is using.

At full brightness on a Pixel, YouTube in dark mode used 43 percent less power than normal. When the video was paused, dark mode saved 60 percent.

On GBoard dark mode saved 21 percent at full brightness. On Google Maps, even at full brightness, using night mode can save about 30 percent of the battery.

Google demonstrated how dark mode minimizes battery drain from the screen.

Salesforce buys Slack in a $27.7B megadeal – TechCrunch

Published

on

Salesforce, the CRM powerhouse that recently surpassed $20 billion in annual revenue, announced today it is wading deeper into enterprise social by acquiring Slack in a $27.7 billion megadeal. Rumors of a pending deal surfaced last week, causing Slack’s stock price to spike.

Salesforce co-founder and CEO Marc Benioff didn’t mince words on his latest purchase. “This is a match made in heaven. Together, Salesforce and Slack will shape the future of enterprise software and transform the way everyone works in the all-digital, work-from-anywhere world,” Benioff said in a statement.

Slack CEO Stewart Butterfield was no less effusive than his future boss. “As software plays a more and more critical role in the performance of every organization, we share a vision of reduced complexity, increased power and flexibility, and ultimately a greater degree of alignment and organizational agility. Personally, I believe this is the most strategic combination in the history of software, and I can’t wait to get going,” Butterfield said in a statement.

Every worker at every company needs to communicate, something that Slack can ably empower. What’s more, it also facilitates external communication with customers and partners, something that should be quite useful for a company like Salesforce and its family of offerings.

Ultimately, Slack was ripe for the taking. Entering 2020 it had lost around 40% of its value since it went public. Consider that after its most recent earnings report, the company lost 16% of its value, and before the Salesforce deal leaked, the company was worth only a few dollars per share more than its direct listing reference price. Toss in net losses of $147.6 million during the two quarters ending July 31, 2020, Slack’s uninspiring public valuation and its winding path to profitability and it was a sitting target for a takeover like this one. The only surprise here is the price.

The new deal also puts Salesforce more on par — and in competition — with its arch rival and sometime friend Microsoft, whose Teams product has been directly challenging Slack in the market. Microsoft, which passed on buying Slack in the past for a fraction of what Salesforce is paying today, has made Teams a key priority in recent quarters, loathe to cede any portion of the enterprise software market to another company.

What really has set Slack apart from the pack, at least initially, was its ability to integrate with other enterprise software. When you combined that with bots, those intelligent digital helpers, the company could potentially provide Salesforce customers with a central place to work without changing focus because everything they need to do can be done in Slack.

The company’s historic growth helped Slack raise over $1 billion while private, earning an impressive $7 billion valuation before going public last year. But while the Glitch-to-unicorn story appears simple, Slack has always faced entrenched competition from the likes of not only Microsoft, but also Cisco, Facebook, Google and even Asana and Monday.com.

Today’s deal comes after Salesforce’s purchase of Quip in 2016 for $750 million. Quip brought a way of socially sharing documents to the SaaS giant, and when paired with the Slack acquisition gives Salesforce a much more robust social story to tell than its internal option Chatter, an early attempt at enterprise social that never really caught on.

It’s worth noting that Salesforce was interested in Twitter in 2016, the same year that Microsoft was reportedly interested in Slack, but eventually walked away from that deal when shareholders objected, not wanting to deal with the controversial side of the social platform.

Slack was founded in 2013, but its origins go back to an online multiplayer game company called Glitch that was founded in 2009. While the game was ultimately a failure, the startup developed an internal messaging system in the process of building that company that later evolved into Slack.

For Slack, the path to the public markets was fraught with hype and outsized expectation. The company was famous, or as famous as an enterprise software company can be. At the time it felt like the its debut was the start of a long tenure as an indie company. Instead, that public life has been cut short by a huge check. Such is the dog-eat-dog world of tech.

Loop Team wants to give remote workers an in-office feel – TechCrunch

Published

on

As we’ve moved to work from home during the pandemic, it’s been challenging for remote workers to feel connected. Loop Team, a new entrant into the enterprise communications space, thinks the way we are communicating needs improvement. That’s why the startup is releasing Loop Team today, a tool that is trying to use software to reproduce the in-office experience.

Company founder and CEO Raj Singh says that he learned about the problems of feeling disconnected first-hand at a previous remote-first company, but in spite of his best attempts to use technology to produce that in-office feel, he said he continued to feel out of the loop (so to speak). That’s when he decided to build the solution he wanted.

“We’ve looked at a lot of the interactions that happen when you’re physically in an office — the visual communication, the background conversations, the hallway chatter, the serendipitous bumping, things like that. And we built an experience that effectively is a virtual office. And so it tries to represent the best parts of what a physical office experience might be like, but in a virtual form,” Singh explained to me.

While he created this company prior to COVID, the pandemic has highlighted the need for a tool like this. Before he created the software, he interviewed hundreds of people who worked from home to understand their issues working outside of the office and he heard a lot of common complaints.

“There was an office and they didn’t necessarily know what was going on. They didn’t know who was available. They didn’t know who was around. It was difficult to connect. Everything was scheduled through calendar. They were missing some of that presence — and they were feeling lonely or out of touch or out of the loop,” he said.

His company’s solution tries to reproduce the office experience using AI, good, old-fashioned presence awareness and other tech to let team members know what you’re doing and if you’re available to chat. So just as you would wander down the hall and see your colleague on the phone or deeply involved with work on the laptop, and know to leave them be, you could get that same feel with Loop.

It gives the current status of the person, and you can know from looking at the list of people on your team, who’s available to talk and who’s busy. As you go into virtual discussions, the team can see who’s having meetings and individuals can pop in too, just as you might do in the office.

What’s more, you can set up rooms (like in Slack), but these are designed to give you a more personal connection using video and audio for actual discussion. You can work on projects via screen share and people who miss these meetings because of other obligations or time zone differences, can always review what they missed.

While you can do all of these things in Slack and Zoom, or in some combination of similar tools, Loop’s layout and presentation is designed to help you see the conversations in a clear way and expose what you want to see, while hiding parts of the day that don’t interest you.

The product is available for free starting today, but Singh wants to introduce a pricing model sometime next year based on team size. He expects there will always be a freemium version for teams under 10 people.

The company was founded in 2018 and nurtured at the Stanford Research Institute (SRI). It has raised $4.75 million so far. Today it starts on its journey as a startup with its first product, and it’s one that comes with good timing as more teams find themselves working remotely than every before.

Facebook’s self-styled ‘oversight’ board selects first cases, most dealing with hate speech – TechCrunch

Published

on

A Facebook -funded body that the tech giant set up to distance itself from tricky and potentially reputation-damaging content moderation decisions has announced the first bundle of cases it will consider.

In a press release on its website the Facebook Oversight Board (FOB) says it sifted through more than 20,000 submissions before settling on six cases — one of which was referred to it directly by Facebook.

The six cases it’s chosen to start with are:

Facebook submission: 2020-006-FB-FBR

A case from France where a user posted a video and accompanying text to a COVID-19 Facebook group — which relates to claims about the French agency that regulates health products “purportedly refusing authorisation for use of hydroxychloroquine and azithromycin against COVID-19, but authorising promotional mail for remdesivir”; with the user criticizing the lack of a health strategy in France and stating “[Didier] Raoult’s cure” is being used elsewhere to save lives”. Facebook says it removed the content for violating its policy on violence and incitement. The video in questioned garnered at least 50,000 views and 1,000 shares.

The FOB says Facebook indicated in its referral that this case “presents an example of the challenges faced when addressing the risk of offline harm that can be caused by misinformation about the COVID-19 pandemic”.

User submissions:

Out of the five user submissions that the FOB selected, the majority (three cases) are related to hate speech takedowns.

One case apiece is related to Facebook’s nudity and adult content policy; and to its policy around dangerous individuals and organizations.

See below for the Board’s descriptions of the five user submitted cases:

  • 2020-001-FB-UA: A user posted a screenshot of two tweets by former Malaysian Prime Minister, Dr Mahathir Mohamad, in which the former Prime Minister stated that “Muslims have a right to be angry and kill millions of French people for the massacres of the past” and “[b]ut by and large the Muslims have not applied the ‘eye for an eye’ law. Muslims don’t. The French shouldn’t. Instead the French should teach their people to respect other people’s feelings.” The user did not add a caption alongside the screenshots. Facebook removed the post for violating its policy on hate speech. The user indicated in their appeal to the Oversight Board that they wanted to raise awareness of the former Prime Minister’s “horrible words”.
  • 2020-002-FB-UA: A user posted two well-known photos of a deceased child lying fully clothed on a beach at the water’s edge. The accompanying text (in Burmese) asks why there is no retaliation against China for its treatment of Uyghur Muslims, in contrast to the recent killings in France relating to cartoons. The post also refers to the Syrian refugee crisis. Facebook removed the content for violating its hate speech policy. The user indicated in their appeal to the Oversight Board that the post was meant to disagree with people who think that the killer is right and to emphasise that human lives matter more than religious ideologies.

  • 2020-003-FB-UA: A user posted alleged historical photos showing churches in Baku, Azerbaijan, with accompanying text stating that Baku was built by Armenians and asking where the churches have gone. The user stated that Armenians are restoring mosques on their land because it is part of their history. The user said that the “т.а.з.и.к.и” are destroying churches and have no history. The user stated that they are against “Azerbaijani aggression” and “vandalism”. The content was removed for violating Facebook’s hate speech policy. The user indicated in their appeal to the Oversight Board that their intention was to demonstrate the destruction of cultural and religious monuments.

  • 2020-004-IG-UA: A user in Brazil posted a picture on Instagram with a title in Portuguese indicating that it was to raise awareness of signs of breast cancer. Eight photographs within the picture showed breast cancer symptoms with corresponding explanations of the symptoms underneath. Five of the photographs included visible and uncovered female nipples. The remaining three photographs included female breasts, with the nipples either out of shot or covered by a hand. Facebook removed the post for violating its policy on adult nudity and sexual activity. The post has a pink background, and the user indicated in a statement to the Oversight Board that it was shared as part of the national “Pink October” campaign for the prevention of breast cancer.

  • 2020-005-FB-UA: A user in the US was prompted by Facebook’s “On This Day” function to reshare a “memory” in the form of a post that the user made two years ago. The user reshared the content. The post (in English) is an alleged quote from Joseph Goebbels, the Reich Minister of Propaganda in Nazi Germany, on the need to appeal to emotions and instincts, instead of intellect, and on the unimportance of truth. Facebook removed the content for violating its policy on dangerous individuals and organisations. The user indicated in their appeal to the Oversight Board that the quote is important as the user considers the current US presidency to be following a fascist model

Public comments on the cases can be submitted via the FOB’s website — but only for seven days (closing at 8:00 Eastern Standard Time on Tuesday, December 8, 2020).

The FOB says it “expects” to decide on each case — and “for Facebook to have acted on this decision” — within 90 days. So the first ‘results’ from the FOB, which only began reviewing cases in October, are almost certainly not going to land before 2021.

Panels comprised of five FOB members — including at least one from the region “implicated in the content” — will be responsible for deciding whether the specific pieces of content in question should stay down or be put back up.

Facebook’s outsourcing of a fantastically tiny subset of content moderation considerations to a subset of its so-called ‘Oversight Board’ has attracted plenty of criticism (including inspiring a mirrored unofficial entity that dubs itself the Real Oversight Board) — and no little cynicism.

Not least because it’s entirely funded by Facebook; structured as Facebook intended it to be structured; and with members chosen via a system devised by Facebook.

If it’s radical change you’re looking for, the FOB is not it.

Nor does the entity have any power to change Facebook policy — it can only issue recommendations (which Facebook can choose to entirely ignore).

Its remit does not extend to being able to investigate how Facebook’s attention-seeking business model influences the types of content being amplified or depressed by its algorithms, either.

And the narrow focus on content taken downs — rather than content that’s already allowed on the social network — skews its purview, as we’ve pointed out before.

So you won’t find the board asking tough questions about why hate groups continue to flourish and recruit on Facebook, for example, or robustly interrogating how much succour its algorithmic amplification has gifted to the antivaxx movement.  By design, the FOB is focused on symptoms, not the nation-sized platform ill of Facebook itself. Outsourcing a fantastically tiny subset of content moderations decisions can’t signify anything else.  

With this Facebook-commissioned pantomime of accountability the tech giant will be hoping to generate a helpful pipeline of distracting publicity — focused around specific and ‘nuanced’ content decisions — deflecting plainer but harder-hitting questions about the exploitative and abusive nature of Facebook’s business itself, and the lawfulness of its mass surveillance of Internet users, as lawmakers around the world grapple with how to rein in tech giants.  

The company wants the FOB to reframe discussion about the culture wars (and worse) that Facebook’s business model fuels as a societal problem — pushing a self-serving ‘fix’ for algorithmically fuelled societal division in the form of a few hand-picked professionals opining on individual pieces of content, leaving it free to continue defining the shape of the attention economy on a global scale.
