- The Nitro 5 features dual fans, plus Acer CoolBoost technology, and a dual exhaust port designed to keep it chilled during extended gaming sessions.
- Above: Acer’s Swift 3 productivity laptop users an AMD Ryzen Mobile processor.
- The Swift 3 uses up to 2nd Gen AMD Ryzen 7 3700U processors with Radeon Vega graphics.
- The new Nitro 5 and Swift 3 with 2nd Gen AMD Ryzen mobile processors will be on display at Acer’s showcase at Xinyi Plaza, Xiangti Avenue Plaza in Taipei on May 28 to June 2, 2019.
How to Build a Realtime Collaborative Spreadsheets App (ie. a Google Sheets Clone)
- This opened up a new world of realtime collaboration, empowering multiple users in the web browser to work together from anywhere on Earth.
- Triggers provide us with a delta, which is then published to PubNub. These would also be triggered after we replay the incoming changes, so we need a way to make sure we don’t get into an infinite loop.
- Instead, we’ll maintain a variable lastSortFromSync where we store the last sort config which was synced to PubNub. If nothing changed in the current sort config, we skip publishing another delta to PubNub. These hooks will by our PubNub listeners, which we’ll get around to it further down in the tutorial.
- Because we’re limiting ourselves to the web browser, we’ll need a way to get new collaborators up and running with the most current state of the spreadsheet.
Animoca Brands raises $2.5 million for The Sandbox blockchain gaming platform
- Animoca’s Pixowl division is remaking The Sandbox as a blockchain-enabled game, with user-generated content that players can buy and sell with real digital ownership, thanks to the blockchain, or a transparent and secure decentralized ledger.
- The investment will accelerate growth of Animoca Brands’ user-generated content (UGC) gaming platform that will empower creators through digital ownership and monetization of 3D voxel creations made and shared by users around the world.
- Development progress on The Sandbox can be seen in a new teaser video released today in conjunction with the announcement, showing a demo of one of the many available biomes where users can create voxel items and gaming worlds from the digital equivalent of building blocks.
- The Sandbox will be offering a high-quality, curated content selection of artist-made voxel models that can be collected for their scarcity and special attributes, in preparation for scripting their behaviors and putting them inside a map to generate new gaming experiences.
Facebook is a capitalism problem, not a Mark Zuckerberg problem
- The other is that it — alongside many of its competitors — is akin to a modern tobacco company, in which fierce competition between firms has led to an arms race in developing techniques to foster digital addiction and hoover up user attention, no matter the social cost.
- Hughes offers a quick and, I think, half-baked idea to form a government agency charged with protecting online privacy and creating “guidelines for acceptable speech on social media.” In an essay that runs for more than 6,000 words, the proposal for regulation comes after a lengthy paean to competition, and receives fewer than 200 words of description.
- Given how important social media platforms have proven to modern life, we should make sure the competition between them serves society’s needs, not just the market’s.
Deaths from strokes in England have halved in just a decade
- Over the course of a decade, the mortality of strokes has halved in England.
- The rate of people dying from this condition decreased by 55 per cent between 2001 and 2010.
- In men, overall death rates dropped from 140 per 100,000 people in 2001, to 74 per 100,000 people in 2010.
- In women, they decreased from 128 per 100,000 to 72 per 100,000.
- In 2001, 42 per cent of men and 44 per cent of women who experienced a stroke did not survive beyond 30 days, the study found.
- By 2010, this figure was 26 per cent in men and 29 per cent in women.
- While the overall number of strokes dropped by around 20 per cent over the decade, there was a rise of 2 per cent every year among people aged 35 to 54 years old.
How to tweet with accessibility in mind
- Not already familiar with "alternative text" or "screen readers"?
- Twitter supports providing alt text for images.
- To opt-in, visit the accessibility tab in your Twitter settings, and enable "Compose image descriptions".
- Camel or pascal cased hash tags are more readable to screen readers, and also more legible for sighted users.
- A tweet would include an ASCII bunny, holding a sign, conventionally with capitalized text.
- Reading this type of text content on a screen reader is...
- A better idea in this case might be to include the meme as an image, with appropriate alt text.
- Twitter bot account, that would politely remind me if I forgot to include alt text.
- The text is read by screen readers in place of images.
- A screen reader is a software program that converts digital text into synthesized speech.
China confirmed as source of illegal ozone-destroying chemicals

- Who is destroying the ozone layer?
- In recent decades, concentrations of chlorofluorocarbon gases have been declining in the atmosphere, which is good news for the ozone layer’s recovery and action on climate change.
- But levels of the second most abundant of those gases, trichlorofluoromethane (CFC-11), have been rising since 2013, puzzling researchers when they detected the increase last year.
- The culprit appears to be illegal production of CFCs in eastern China, in defiance of a 2010 ban on their manufacture.

MIT CSAIL’s AI system lets wearers control robots with their biceps
- Toward that end, DelPreto and colleagues’ project — which builds on an existing system that let users correct robot mistakes with brainwaves and hand gestures — incorporates bicep and tricep electromyography (EMG) sensors that monitor muscle activity, along with an algorithm that parses detected neuron-muscle firing.
- Slightly tensing or relaxing an arm moves the team’s Baxter humanoid robot up or down, while gesturing up or down moves the robot farther away or holds a pose.
- New users tense and relax their arm a few times, lift a weight to a few heights, and they’re good to go.
- Already, they’ve prototyped a version that uses bicep and tricep levels to tell the robot how stiffly an object’s being held, which they say could enable the robot to fluidly drag an object around or rigidly pull it taut.
TikTok's parent company ByteDance is launching a music streaming service as soon as this fall
- ByteDance, the world's most valuable start-up and parent to short-form video sharing app TikTok, is reportedly set to launch a music streaming service as soon as fall 2019, per Bloomberg.
- Here's what it means: ByteDance is looking to target emerging markets — and India in particular — with its new service.
- The bigger picture: ByteDance's new platform could pose a serious threat to Spotify, which has been eyeing India, and APAC more broadly, for future growth.
- ByteDance's streaming service will likely mirror the model of rival-to-be Spotify, which has done well in emerging markets due to its ad-supported tier.
- The company reported 1 million new users within its first week of launch, significant given the fact that Indian competitor Gaana already boasted 80 million users.
Drone can transform into a tiny car to slide under small gaps
- A shape-shifting drone can transform into a car once it touches down.
- FSTAR has a wheel and a propeller on each of its four legs.
- During operation, a human pilot uses a controller to drive FSTAR and change its configurations.
- When FSTAR is flying as a quadcopter, its four legs are in the same plane as its body, parallel to the ground.
- When it lands and receives the commend to turn into a car, a motor on FSTAR’s body pulls its legs from horizontal to vertical so that its wheels touch the ground.
- However, instead of being perpendicular to the ground like those of a regular car, FSTAR’s wheels are slanted, similar to the sprawling legs of a spider.
- FSTAR can drive at up to 2.6 metres per second and reaches 15 metres per second when flying.
