A simple vista parece una pila de las que usan los viejos relojes de pulsera. Pero no. Se trata de una minúscula batería de litio construida con la ayuda de nanotubos, diseñada por Nokia e investigadores del Trinity Collage de Dublín. Su propósito: dotar de poder a los dispositivos que irán conectados dentro de la futura red 5G. Equipos de los que ya se sabe, consumirán mucha, pero mucha energía.

No solo Smartphones. Los pequeños cilindros están pensados para usarse en drones, coches eléctricos y en cualquier electrodoméstico o producto que esté dentro de IoT.

Nanotubos de carbono forman la base principal de esta fuentes de poder, además del litio que sirve de ‘soporte’ de almacenamiento. Más allá de su sorprendente tamaño, las velocidades de transferencia de energía alcanzan – según sus creadores – picos de eficiencia hasta ahora teóricos. Así como una rapidez de carga sencillamente increíble.

Pixel 4 and Pixel 4 XL is currently ‘out of stock’ on the Google Store

pixel-4-and-pixel-4-xl-is-currently-‘out-of-stock’-on-the-google-store

At the start of July, Google discontinued the Pixel 3a after inventory ran out on its official store. After announcing its latest mid-range phone on Monday, the flagship Pixel 4 and Pixel 4 XL is currently out of stock on the Google Store.

As of Wednesday evening, the Pixel 4 is listed as being “Out of stock” in the US store. The config page reflects that status as well for Verizon, Unlocked, and Google Fi units. Google Stores abroad still have the device on sale, but many variants are sold out.

Meanwhile, Google’s MVNO website no longer even lists the Pixel 4 or Pixel 4 XL. It’s still available at third-party retailers and carriers, but stock is dwindling. We’ve reached out to Google for comment.

With the Pixel 4a not launching in the US until August 20th, this means you cannot buy a Pixel phone directly from Google for the next two weeks. This departure is highly uncharacteristic as the replacement hasn’t been fully detailed yet, much less available for purchase. Last year’s flagship is usually available (and heavily discounted) for several months after the new phone launches.

The Pixel 4 ($799+) and Pixel 4 XL ($899+) was announced last October at Made by Google 2019 in New York City. It’s powered by a Snapdragon 855 processor with 6GB of RAM, which was the first time Google increased RAM since launching the Pixel line in 2016, and 64 or 128GB of storage.

The smaller phone has a 5.7-inch display and 2,800 mAh battery that was criticized for being too small given the 90Hz Smooth Display. Meanwhile, the 6.3-inch 4 XL rocks a 3,700 mAh battery.

Another first is the jump to a dual-camera array. The 12.2 MP main sensor is paired with a 16MP telephoto, bucking the trend of other manufacturers opting for wide-angle lenses.

Instead of a standard fingerprint sensor, Google opted for IR-based face unlock that also takes advantage of Soli to speed up detection. This radar sensor has been in development for the past several years, but the Advanced Technology and Projects group finally miniaturized the chip. It is used for hand gestures and turning off the always-on display when you’re not near the Pixel 4.

The “something special” teased by Google over the weekend is a month-long series of deals. Fred Armisen is the face of the Google Store Daily Special with various skits showing off various Assistant devices and how they are helpful.

For the next month, there will be a “Daily Special” on a Made by Google product in the US Google Store. The site’s top navigation adds a new section that previews what’s coming next, while there’s free two-day shipping by entering this code — GOOGLESTORE2DAY — at checkout.

The company is partnering with Fred Armisen of Saturday Night Live, Portlandia, and Documentary Now! fame. The comedian plays all the characters in this series with funny voices, costumes, and elaborate wigs. Each product has an angle with the Nest Mini being called “The Nest Meditation Guru.”

We’ll be keeping a running list of all the deals, so be sure to follow and bookmark this page:

The 10-inch Smart Display was announced last year at I/O 2019, but did not launch until September. Besides the bigger screen for watching videos and TV, there are stereo speakers and a 3-inch woofer.

Monday, July 13: Nest Mini

The first Daily Special on the Google Store is $20 off a Nest Mini 2-pack. Normally $98, it will cost $78 until Sunday, July 19 at 11:59 p.m. PT.

https://store.google.com/config/daily_special_nest_mini_two_pack

Announced at Made by Google 2019, this is the company’s newest Nest product. It looks identical to the first-generation, but touts 2x stronger bass from a 40 mm driver and “improved voice recognition” with 3 far-field microphones. It’s powered by a quad-core 64-bit ARM CPU at 1.4 GHz and a “high-performance ML hardware engine” for more on-device processing.

As you approach, the LEDs automatically turn on to show the volume, while the Nest Mini can be mounted on the wall with an integrated mount/groove on the underside. As part of an environmental push, the fabric cover — available in Chalk (gray), Sky (Blue), Coral (orange), and Charcoal (black) — is made of recycled plastic bottles.

Google resumes human review of Assistant audio, requires opt-in for ‘recordings’

Published

on

google-resumes-human-review-of-assistant-audio,-requires-opt-in-for-‘recordings’

Last summer, Amazon, Apple, and Google were criticized for not properly disclosing how human reviewers analyze audio snippets from each of their assistants. Google in response paused the practice for Assistant and other products, but is now resuming and making audio recordings entirely opt-in.

As noted by The Verge, Google is sending out a somewhat confusing email about how it “recently updated settings for voice and audio recordings.” The crux is how the company is having human reviewers analyze audio snippets again.

This process — which involves listening, transcribing, and annotating — improves Google’s speech recognition technology, and helps expand support to more languages. As of last year, only 0.2 percent of all snippets are reviewed by humans.

These language experts review and transcribe a small set of queries to help us better understand those languages. This is a critical part of the process of building speech technology, and is necessary to creating products like the Google Assistant. 

In restarting the program, Google “turned [the audio recordings setting] off for you until you are able to review the updated information.” This happened earlier in the week and the email serves as an advisory.

As a result, visiting activity.google.com will no longer let users listen to audio of their commands. You just see the text transcript, while Google notes how there is “no impact to your previously saved audio data.” 

L: Before opt-in | R: After opt-in

The settings page to enable/disable has a short video recapping the how and why. Tapping the button underneath to enable presents another explainer, with “I agree” in the bottom-right corner.
