Vu sur le web > L’IA peut devenir bilingue sans aucune aide

http://ift.tt/2q0XwI3

Est-ce que les traducteurs, qui passent des heures à trouver le bon terme pour bien traduire un texte, doivent se sentir menacés ? Pas encore. Mais le résultat de deux recherches totalement différentes et pourtant semblables montrerait qu’une Intelligence Artificielle est capable de devenir bilingue sans aucune aide. Sans aide humaine, déjà, mais également sans dictionnaire. Une avancée majeure qui doit toutefois être vérifiée.

Ce sont les recherches de Mikel Artetxe et Guillaume Lample qui pourraient améliorer la traduction automatique de textes. Mais on est encore loin du résultat d’un traducteur humain expérimenté.

L’apprentissage non supervisé : une nouvelle technique pour l’IA

Que l’Intelligence Artificielle sache traduire plus ou moins un texte correctement n’est pas une nouveauté : on a tous utilisé Google Translate et des services similaires. Mais l’apprentissage se fait alors avec un superviseur humain : l’IA tente une traduction, l’Homme lui dit si elle est juste ou fausse et l’IA apprend de ce retour.

Artexte et Lample, dans deux recherches distinctes, se sont penchés sur un nouveau système : l’apprentissage non supervisé. Les deux chercheurs ont développé deux systèmes distincts : le premier est la « 

traduction retour

 » (

Back Translation

) d’Artexte, le deuxième la traduction par « 

suppression de bruit

 » de Lample.

Mais pour commencer les deux systèmes ont dû créer un « 

dictionnaire bilingue

 » en ne se basant que sur les occurrences de certains termes dans deux langues distinctes. Par exemple : les termes table et chaise sont utilisés souvent à proximité en français et en anglais ; une IA est en mesure de reconnaître ces occurrences et de faire le rapport entre « 

chaise

 » en français et « 

chair

 » en anglais.

Un niveau encore très bas par rapport à Google Translate

La « 

traduction retour

 » d’Artexte propose de travailler de la manière suivante : l’IA prend le texte en langue A puis le traduit en langue B et le retraduit en langue A. Si la traduction finale n’est pas identique à la phrase initiale, l’IA va retravailler ses connaissances et s’améliorer.

Du côté du système de Lample, l’idée est la même mais entre la traduction aller et la traduction retour, Lample ajoute du « 

bruit

 », comme la suppression d’un terme ou la modification de l’ordre des mots. Là aussi, l’IA va apprendre de ses erreurs si la traduction retour n’est pas identique à la phrase d’origine.

Les deux systèmes ne sont toutefois pas encore au point : par rapport à l’apprentissage supervisé de Google Translate, qui réussit un score de 40 lors des évaluations, ou par rapport à un traducteur humain capable de réaliser un score supérieur à 50, cette méthode non-supervisée n’obtient qu’un score de 15 pour l’instant. Mais le champ de recherche est important, puisqu’une telle méthode permettrait de mettre au point des traductions automatiques pour des langues où il n’existe que peu de documents déjà traduits.

Vu sur le web > What to Expect From Apple in 2018: Three New iPhones and iPad Pro With Face ID, HomePod, Refreshed Macs, and More

http://ift.tt/2C9uECT

Like 2017, 2018 promises to be a major year for Apple, with many new products on the horizon. We’ll get Apple’s first smart speaker — the HomePod — this year, along with a second-generation version of the iPhone X accompanied by a larger-screened version for those who want to go even bigger.

A new iPad Pro with Face ID is said to be in the works, and this is also the year when Apple’s AirPower wireless charging mat will debut. Beyond that, we can expect Mac refreshes, new software, a new Apple Watch, and maybe that new modular Mac Pro.

Subscribe to the MacRumors YouTube channel for more videos.


Below, we’ve rounded up all of the products we’re expecting to see from Apple in 2018 based on both current rumors that we’ve heard so far and past release information.

HomePod – Early 2018

HomePod is Apple’s first Wi-Fi connected smart speaker, designed to compete with existing smart speakers like the Amazon Echo and the Google Home. It was originally meant to debut in December, but Apple delayed its launch to an unspecified date in "early 2018."

With HomePod, Apple focused on sound quality, with a 7 tweeter array, each with its own driver, and a 4-inch upward-facing woofer for crisp, distortion free sound. An A8 chip powers spatial awareness features, allowing the HomePod to analyze a room and then adjust the sound accordingly.



Siri is built into HomePod, and there’s integration with Apple Music for Apple Music subscribers. Using a six-microphone array, HomePod can detect Siri commands from anywhere in a room, so Siri can be used to play music, answer queries, and more.

We don’t know exactly when HomePod will be released, but it should come out in the first few months of 2018. Apple plans to charge $349 for the speaker.

Read more about HomePod in our HomePod roundup.

Three New iPhones – September 2018

Apple introduced three iPhones in 2017 — the iPhone X, the iPhone 8, and the iPhone 8 Plus — and current rumors suggest we’ll also see three new models in 2018.

The first iPhone we’re expecting will be a followup to the iPhone X with the same 5.8-inch OLED display. Rumors suggest it will be accompanied by a second OLED iPhone, this one measuring in at 6.5 inches, which means it can be thought of as an "iPhone X Plus."

Alongside these two OLED iPhones, Apple is also said to be planning to introduce a 6.1-inch iPhone with an LCD display, positioned as a more affordable device targeting the low-end and midrange markets with a starting price of $649 to $749 in the United States.

According to KGI Securities analyst Ming-Chi Kuo, all three of these iPhones will feature edge-to-edge displays, Face ID, and TrueDepth camera systems, which means the end of both the Home button and the Touch ID fingerprint sensor in new iPhone models for the time being.

Kuo believes the 5.8-inch model will have a display with 458 pixels per inch, indicating the same 1125 x 2436 resolution as the iPhone X, while the larger 6.5-inch OLED model will offer 480 to 500 pixels per inch. The LCD model, which, as mentioned, will be positioned as a lower cost device, will have a lower-resolution LCD display with 320 to 330 pixels per inch.

Kuo’s predictions are often accurate, and he was able to share many details on the iPhone X ahead of its launch, so the three-iPhone rumor is credible.

It’s not clear what other features we may see in the 2018 iPhones aside from Face ID and edge-to-edge displays across the board, but a faster processor is a guarantee, and Apple may also adopt improved battery technology to offer longer battery life. New LTE modems are also in the works, which will allow for faster LTE connections.

All of the new iPhones are likely to use the same general design as the iPhone X, with glass bodies to support wireless charging, though one unsubstantiated rumor has suggested the lower-end device might instead include a metal frame.

With the iPhone X, Apple changed its naming scheme for the iPhone, so it’s anyone’s guess what. the 2018 devices will be called. Apple could name the next-generation iPhone X and its larger sibling the iPhone XI and the XI Plus, but it’s not clear if that’s what the company plans to do.

Read more about what’s coming in the 2018 iPhones in our iPhone X roundup.

iPad Pro – September 2018?

Face ID has been well-received in the iPhone X, and rumors suggest Apple is planning to deploy it to additional devices, including the iPad Pro.

A high-end 2018 iPad Pro could adopt many of the design elements of the iPhone X, with slimmer bezels, no Home button, and Face ID powered through the same TrueDepth camera system introduced in the iPhone X.

A faster processor and custom Apple-built GPU are also rumored for the new tablet, but it’s not expected to gain an OLED display, with Apple continuing to use an LCD because of technical and financial constraints.

We haven’t heard rumors on the size of this updated tablet, but Apple is likely to stick with the 10.5-inch form factor. Whether we’ll also see a 12.9-inch iPad Pro with slimmer bezels and no Home button remains to be seen, but a separate rumor has said all 2018 iPad Pro models will feature Face ID and a TrueDepth camera.

Apple may also have a new version of the Apple Pencil in the works, but what improvements might be included aren’t known at this time.

Rumors suggest Apple may introduce the iPad Pro "a little more than a year" after the prior iPad Pro update, which was in June, so we may see the 2018 iPad sometime around September.

Read more about the next-generation iPad Pro in our iPad Pro roundup.

Low-cost iPad – Early 2018?

In 2017, Apple introduced a new 5th-generation 9.7-inch iPad with the lowest price we’ve seen yet – $329 for the 32GB model. Though not as thin as the iPad Pro, and missing features like Apple Pencil support and ProMotion display technology, the iPad has an A9 processor and is a capable, powerful device.



Rumors suggest Apple could introduce an even lower-cost iPad in 2018, with a price tag that starts at $259. That would allow Apple to better compete in the lower cost tablet market. This rumor comes from DigiTimes, though, a source that’s not always entirely reliable, so it’s not yet clear if Apple does indeed have an even more affordable iPad in the works.

If there is a new iPad coming, it could be introduced in early 2018, a year after the March 2018 debut of the fifth-generation iPad.

Read more about what’s next for the iPad in our iPad roundup.

Apple Watch Series 4 – September 2018

Apple has been updating the Apple Watch on an annual basis, so we’re expecting to see a fourth-generation model in 2018. These updates have come in September alongside the iPhone for the last two years, and Apple will likely follow the same schedule for 2018.

The Apple Watch has not seen a redesign since it was first introduced in 2015, so 2018 could be the year that Apple introduces a new look for the wrist-worn device. We haven’t heard rumors about a redesigned fourth-generation model, but there was some talk about a redesign for the Apple Watch Series 3.



That didn’t happen, but there’s a possibility that info was referring to an Apple Watch coming at a later date because it did come from a reliable source – Daring Fireball‘s John Gruber.

Rumors have suggested Apple will perhaps use micro-LED displays for the 2018 Apple Watch, which would allow for a thinner, lighter display with improved color gamut and brightness.

New sensors could also be in store, as Apple has been testing EKG functionality for the Apple Watch. The feature would require users to place two fingers on either side of the Apple Watch to record the electrical activity of the heart to better detect irregularities. It’s not known if this functionality will be ready to debut in 2018.

Other sensors could be in the works, as could accessories that add new health-related capabilities to the device. Apple has been testing non-invasive blood glucose monitoring techniques, but it’s not likely this is something ready to debut in a product, and while Apple has patented bands that have built-in sensors, it’s also not clear if this is something that will come to fruition. Both are possibilities, though.

Read more about the next Apple Watch in our Apple Watch roundup.

AirPower Charging Mat

The iPhone 8, 8 Plus, and X introduce support for Qi-based inductive charging for the first time, allowing them to work with Qi-certified chargers. There’s no Apple designed charger on the market yet, but as Apple announced in September, an accessory is in the works.



Called the AirPower, Apple’s wireless charging device is designed to charge the Apple Watch, the AirPods, and the iPhone X, iPhone 8, or iPhone 8 Plus all at the same time. It will work with the three newest iPhones, the Apple Watch Series 3, and the AirPods with a new inductive charging case that’s in the works.

Apple has not announced pricing or a launch date beyond the nebulous "2018" for the AirPower, but rumors suggest it could cost somewhere around $199 in the United States.

Next-Generation AirPods – Mid to Late 2018

Apple in September introduced a second-generation AirPods case that’s coming out in 2018 alongside the AirPower charging mat, which is designed to allow the AirPods to charge wirelessly.



In addition to this inductive charging case, Apple is also said to be planning to debut an upgraded version of the AirPods themselves in the second half of 2018. There’s no real word on what improvements might be made to the AirPods in 2018, but a "smaller quartz" component is one prediction from KGI Securities analyst Ming-Chi Kuo, the source of the rumor.

Better Bluetooth connectivity, an upgraded W1 chip, and new color options are all possible features Apple could introduce in updated 2018 AirPods, but nothing is confirmed at this point.

iMac and iMac Pro – Mid-to-Late 2018?

Apple refreshes the iMac on a yearly basis, so we’re likely to see updated 21.5 and 27-inch machines with 8th-generation Coffee Lake chips from Intel. The bump to Coffee Lake should introduce some nice speed improvements, as Intel says they’re up to 32 percent faster than previous-generation chips.

The iMac hasn’t seen a design refresh since 2012, but it’s not yet clear if other changes are in store beyond updated internals.



As for the iMac Pro, it’s a new product that was just introduced in December of 2017, so we don’t yet know its refresh schedule. In the past, Apple has not updated its pro machines on a yearly basis, so it’s not yet clear if it will be refreshed with updated components in 2018.

Read more about iMac and iMac Pro in our iMac and iMac Pro roundups.

MacBook Pro – June?

The MacBook Pro is typically refreshed on an annual basis, and 2018 should be no different. We’re expecting a minor spec bump with 8th-generation Kaby Lake Refresh chips, and perhaps some other improvements that include faster RAM and SSDs.

In 2017, KGI Securities analyst Ming-Chi Kuo said Apple was working on a higher-end MacBook Pro machine for professional users with 32GB RAM, set for a 2017 launch, but no such machine materialized. Whether there’s actually such a product in the works remains to be seen.



Given that the MacBook Pro’s design was just updated in 2016, we’re not expecting any design changes in 2018. The last refresh was in June of 2017, so a 2018 refresh could also happen in June following the Worldwide Developers Conference.

Read more about the MacBook Pro in our MacBook Pro roundup.

MacBook – June?

The MacBook is another machine that Apple normally updates on an annual basis, and this year’s refresh is likely to introduce 8th-generation Kaby Lake Refresh chips for speed and efficiency improvements.



Other internal components could also be updated, but no external design changes are expected as it’s only been two years since the MacBook came out.

Read more about the MacBook in our MacBook roundup.

New Software – June Preview, September Release

Apple in 2018 is expected to introduce new versions of the software that runs on iOS devices, Macs, the Apple Watch, and the Apple TV. In 2018, we expect to see iOS 12, macOS 10.14, watchOS 5, and tvOS 12.

As it does every year, Apple is likely to introduce these new software updates at the Worldwide Developers Conference, typically held in June. Following WWDC, beta versions will be provided to developers and eventually public beta testers for testing purposes ahead of an eventual September release alongside new iPhones and other new products.



We haven’t heard a lot about what we can expect to see in iOS 12, macOS 10.14, watchOS 5, and tvOS 12, but one rumor has suggested Apple is working on a universal app solution that would allow developers to create apps that work across iPhone, iPad, and Mac. Currently, developers must develop apps for iOS and macOS separately.

A unified app system would mean developers could create a single app able to run on iPads, iPhones, Macs, the Apple Watch, and the Apple TV with less effort, as currently, iOS apps can already be extended to the Apple Watch and the Apple TV.

Apple is tentatively planning to introduce this universal app change in iOS 12 and macOS 10.14.

No other hints on what we can expect in next year’s software updates have surfaced as of yet, but we’re likely to learn more as the next Worldwide Developers Conference approaches.

Products We Might See

Apple TV Shows

Apple is delving into original television programming in a big way, and it’s possible the first of the company’s new TV shows could launch in 2018.

So far, Apple has purchased the rights to three new TV series: an "Amazing Stories" reboot with Steven Spielberg based on the original sci-fi show that ran from 1985 to 1987, an untitled "morning show drama" starring Reese Witherspoon and Jennifer Aniston, and an untitled space drama developed by Ronald D. Moore, best known for creating the 2004 reboot of Battlestar Galactica.

Amazing Stories from 1985


The morning show drama is described as an "inside look at the lives of the people who help America wake up in the morning," while the space drama "explores what would have happened if the global space race had never ended."

Apple just recently purchased all three of these shows and none of them are in production, so it’s not entirely clear when exactly each one will debut.

Read more about Apple’s original content plans in our Apple TV roundup.

Mac mini

The Mac mini, which hasn’t been updated since 2014, is in dire need of a refresh. We’ve heard no real word about work on a new Mac mini machine, but in October of 2017, Apple CEO Tim Cook said Apple plans for Mac mini to be "an important part" of the Mac product lineup going forward.



We don’t know if 2018 is the year when the Mac mini will finally be overhauled and updated, but it’s a possibility. If Apple does plan on introducing a Mac mini update at some point, it could come in June or September, and it could include 8th-generation Kaby Lake Refresh processors from Intel and Thunderbolt 3 support.

Read more about the Mac mini in our Mac mini roundup.

Mac Pro and Display

Apple in April announced plans to introduce a next-generation high-end high-throughput modular Mac Pro that will facilitate regular upgrades to meet the needs of the company’s pro user base. Apple plans to ship the machine alongside an upcoming Apple-branded pro display.

Work on the new Mac Pro didn’t commence until spring of 2017, and all Apple said about a release date is that it wouldn’t be ready in 2017. Apple’s made no mention of 2018, but it’s possible the Mac Pro will come late in the year. We may, in fact, hear more about it at the Worldwide Developers Conference, which will likely take place in June.

Apple has a dedicated team working on the Mac Pro, designed specifically for "demanding pro customers." Apple is committed to making the Mac Pro the highest-end desktop system able to accommodate VR and high-end cinema production.

Read more about the Mac Pro in our Mac Pro roundup.

New iPhone SE

People who prefer smaller 4-inch iPhones are undoubtedly hoping for a new version of the iPhone SE, the updated 4-inch device Apple introduced in the spring of 2016. We really haven’t heard any concrete, reliable rumors suggesting another version of the iPhone SE is in the works, but there have been some less credible hints.



Supply chain sources told Taiwan’s Economic Daily News that a second-generation iPhone SE is in the works for the first half of 2018, with the device to be assembled by Taiwanese manufacturer Wistron at its factory in Bangalore, India.

An entirely questionable and unverified rumor from Indian site Tekz24 has said the next iPhone SE will include an A10 chip, 10GB RAM, a 12-megapixel rear camera, a 5-megapixel front-facing camera, and thinner side bezels, but we’re not sure that’s accurate information.

Read more about what’s next for the iPhone SE in our iPhone SE roundup.

What’s Not Likely in 2018

New Apple TV

The Apple TV 4K was released in September of 2017, and so far, Apple hasn’t been doing yearly Apple TV updates. Prior to the 2017 release of the Apple TV 4K, there was an updated model released in 2015, but no 2016 refresh.



With an A8 processor in the Apple TV 4K, it’s fast enough to hold up for a few years, so we’re not expecting to see a new Apple TV in 2018.

Read more about the Apple TV in our Apple TV roundup.

MacBook Air

Apple refreshed the MacBook Air in 2017 with slightly faster Broadwell processors, but aside from that, the device, which is Apple’s most affordable laptop, has not been updated since 2015.



Apple is likely phasing the MacBook Air out in favor of the MacBook and the 13-inch MacBook Pro, both of which make the "Air" moniker antiquated with their slimmer bodies. The MacBook and the 13-inch MacBook Pro are still not machines Apple is able to sell for under $1,000, so the MacBook Air may stick around for another year or two in its current incarnation. No upgrades are expected, though.

Read more about the MacBook Air in our MacBook Air roundup.

AR Smart Glasses

We’ve heard multiple rumors suggesting Apple is prototyping augmented reality smart glasses and virtual reality headsets, but while these products are in development, a release is not expected for a couple of years yet.

An AR/VR headset built by VRvana, a company Apple purchased in late 2017


According to the most recent rumors, Apple is working on an augmented reality headset with a dedicated display, built-in processor, and a new "rOS" operating system based on iOS, with the "r" standing for reality. Apple is said to be aiming to finish work on an augmented reality headset by 2019 ahead of a launch it hopes will come in 2020.

A new version of ARKit is rumored to be in development, though, and that could come as soon as 2018. New ARKit functionality could include multi-player game support and support for persistent tracking. Apple in November bought its first VR/AR hardware company, VRvana. VRvana developed a virtual reality headset called Totem, which was designed to combine both augmented and virtual reality technologies in a single headset.

Read more about Apple’s work on augmented reality in our AR/VR roundup.

Apple Car Software

Apple is working on an autonomous driving system, but development on the software is still in the early stages and it’s not likely we’ll see any kind of finished product in 2018. Testing is ongoing on the roads around Apple’s Cupertino offices using autonomous driving software and specialized equipment installed in Lexus SUVs.

One of the Lexus SUVs Apple is using to test its autonomous driving software


While no finished products are expected, we may hear more about Apple’s work on autonomous software throughout the year. It’s not really clear when something will come of Apple’s efforts.

La synthèse vocale de Google passe encore un cap

Difficile à distinguer d’une voix humaine

Le savoir-faire des équipes de Google en matière de recherche sur l’intelligence artificielle n’est plus à prouver, mais écouter ce dont est capable Tacotron 2 permet de se rendre compte — une nouvelle fois — des prouesses dont elles sont capables.



Google a présenté cette semaine Tacotron 2, son nouveau moteur de synthèse vocale qui produit des résultats d’un réalisme bluffant. Derrière cette voix se cachent deux intelligences artificielles qui travaillent de concert. Un premier réseau neuronal profond se charge de convertir le texte en « spectrogram » (une représentation visuelle des fréquences audio), tandis que WaveNet (un outil mis au point par DeepMind, le laboratoire d’IA de Google) se charge d’interpréter ces données en générant les sons correspondants.


Outre une dictée d’un naturel assez époustouflant, les améliorations apportées par Tacotron 2 sont nombreuses. Ce moteur gère mieux les mots complexes, est capable d’adapter la prononciation des mots à la sémantique des phrases, réagit parfaitement à la ponctuation et peut aussi retranscrire le stress et diverses intonations. Pour vous faire une idée de ses capacités, rien de tel que d’aller écouter

les extraits proposés sur Github par Google

.


Pour l’heure, Tacotron 2 reste en développement. Le système est, par exemple, seulement capable de générer une voix féminine. Mais Google entend rapidement pouvoir l’utiliser au sein de ses solutions commerciales, dont Google Assistant — évidemment.

Vu sur le web > L’Apple Store de Chicago n’a pas été conçu pour la neige

http://ift.tt/2lfbTna

Le nouvel Apple Store de Chicago inauguré en octobre est magnifique, mais ses architectes (Foster + Partners) ainsi qu’Apple ont visiblement oublié que la ville n’était pas particulièrement la plus chaude des États-Unis et que la neige y élisait parfois domicile.

Cliquer pour agrandir

Résultat, le très beau toit de la boutique, avec ses lignes effilées sur les tranches ne retient pas la glace ni la neige et encore moins lorsque tout cela fond. Ce qui transforme les abords du store en patinoire. Obligeant, dans le cas présent, Apple à condamner temporairement la circulation des piétons autour du magasin.

C’est d’autant plus gênant que ces abords ont été aménagés avec des escaliers pour que les gens descendent vers l’une des deux entrées du store, ou aillent se promener au bord de la rivière Chicago en contrebas. Arriver à corriger ce défaut sans toucher aux lignes minimalistes du bâtiment ne sera peut-être pas une mince affaire.

Vu sur le web > Apple is being slandered for what chemistry cannot fix

http://ift.tt/2E2lXrh

Robert Kientz, Seeking Alpha (free reg-wall):

Li-ION is the most advanced, commonly available batteries that are used in portable electronics like laptops and phones. That is because unlike Nickel Cadmium [NiCad], they do not develop ‘charge memories’. And they are better for small electronics than Nickel Metal Hydride [NiMH] because of shorter charge time and higher energy density, both critical for the uses of portable phones.

And:

Li-ION batteries typically fail faster than NiCad because they wear out in less charge cycles, which mean consumers get fewer charges before their batteries will need replacement.

And:

Apple has not designed flaws into its iPhone product with regard to battery management.

What Apple has done is provide software that allows its iPhone users who want to keep their phones to manage their batteries by slowing down the processor during times of lower power and to keep the phones from turning off spontaneously. Contrary to what many have said about this story, what Apple is doing is not abnormal at all.

There are two computer chip manufacturers that you may have heard of, Intel and Advanced Micro Devices, Inc. (AMD), that have built advanced power management technology into their chipset designs.

Great read. To me, Apple has done an amazing job optimizing its battery technology. Where they’ve slipped up here, in my opinion, is in communications. This would not be an issue of Apple gave users an easy way to tell where their device sits on the battery efficiency curve, made it easier for a user to have a sense of how much better their device would perform if they bought a new battery.

That said, I’m not sure Apple wants to be in the battery swap-out business. If Apple educated their users about the current state of their batteries, I suspect many consumers would develop a habit of updating their batteries, rather than live with a 75% solution.

Vu sur le web > LastPass Authenticator Android app is easy to break into

http://ift.tt/2l9MmvJ

Password managers are supposedly the cure for the seemingly innate human tendency to use weak passwords. A special class of password managers take it a step further by using two-factor or two-step authentication or 2FA. But what is said authentication manager itself isn’t as bulletproof as it should be? That is the rather odd situation that users of LastPass Authenticator on Android now find themselves in after it was revealed that it is almost trivial to get into the app and access the 2FA codes need, in turn, to get access to accounts and private data.

To be clear, it isn’t the main LastPass password manager that’s being deemed woefully insecure here. That one uses different security measures in order to make sure no one but you has access to your passwords. Measures that are, ironically, not applied to the LastPass Authenticator app on Android.

Like any Authenticator, the app works in lieu of sending an SMS to give the user a code to sign into an account. But according to dylan from Hacker Noon, it’s virtually easy to get access to that code on Android. No root access required and no physical access even needed. The hacker simply need to get access to a specific activity or “page” of the app, which is unprotected by any sort of lock, PIN, or fingerprint authentication.

Granted, the circumstances that would lead to a remote access to the Authenticator may be a bit contrived. A malicious app must already be installed, waiting for the moment when the LastPass Authenticator is needed and then steal a 2FA code. Alternatively, the malware itself could attempt to log into some account and use LastPass Authenticator to get in.

Contrived or not, it isn’t an excuse to leave any door open for such a critical piece of security software. dylan claims to have informed LastPass of the vulnerability way back in June and received confirmation that it was reproducible. LastPass has gone silent since then but now that it has gone public, it had no other choice but to say “we’re working on it”.

Vu sur le web > iPhone X : Apple reverrait à la baisse ses objectifs de vente pour le premier trimestre 2018

http://ift.tt/2zyt7jT

Après avoir chanté les louanges de l’iPhone X et les ventes exceptionnelles du dernier-né de la Pomme, les analystes changent leur fusil d’épaule et tirent la sonnette d’alarme en avançant un net recul des expéditions pour le premier trimestre 2018.

D’après l’analyste Zhang Bin, les marchés financiers s’inquièteraient désormais que le tarif très élevé de l’appareil devienne un véritable frein pour les acquéreurs potentiels, qui se rabattraient plus volontiers sur les modèles 8 et 8 Plus.

Pour JL Warren Capital LLC, Apple devrait ainsi écouler « seulement » 25 millions d’iPhone X au premier trimestre 2018, soit 5 millions de moins qu’au quatrième trimestre 2017, malgré une vaste campagne de promotion.

Même son de cloche du côté de l’Economic Daily News, qui affirme qu’Apple revu à la baisse ses prévisions, et table désormais sur 30 millions d’iPhone X distribués au quatrième trimestre, au lieu d’une estimation initiale de 50 millions d’unités. Le site taïwanais précise enfin que Foxconn a cessé d’embaucher de nouvelles recrues pour faire tourner les chaines de production du dernier smartphone d’Apple.

The iPhone X may be expensive, but that doesn’t make it any less interesting. The best iPhone Apple has ever made has been sold out around the world since it hit preorders early on October 27th. But people are still flocking to buy it, and China seems to be a hot market for Apple right now.

Apparently, the iPhone X is responsible for more upgrades in the region, but it’s also convincing more Android users to switch.

Vu sur le web > TV : le décrochage des jeunes va continuer en 2018, mais moins vite que prévu

http://ift.tt/2kVfsOA

Par Alexandra Yeh, France Télévisions, Direction de l’Innovation

Des jeunes qui continuent à déserter la télé, mais moins vite que prévu : c’est le futur que prédit Deloitte au petit écran dans la dernière édition de son rapport Technology, Media and Telecommunications Predictions, qui porte sur les jeunes de 18 à 34 ans aux Etats-Unis, Canada et au Royaume-Uni. Un pari pas trop risqué au vu de l’évolution de leurs usages ces dernières années…

Un déclin structurel, mais constant

Selon Deloitte, l’usage de la télévision linéaire chez les 18-24 devrait reculer de 5 à 15% sur ces trois marchés durant les deux années à venir, pour atteindre une consommation quotidienne de 80 à 120 minutes (avec des variations selon la période de l’année). Un déclin de la TV traditionnelle qui se confirme donc, mais qui devrait rester constant dans les mois à venir, sans s’aggraver.

Car comme l’explique le rapport, « le pire semble être passé » : depuis 2014, année noire pour les scores d’audience des jeunes, le recul du tube cathodique s’est stabilisé. Et attention, prévient Deloitte, le ralentissement du recul de la TV en 2016 ne s’explique pas par un soudain regain d’amour des Millennials pour la télévision, mais plutôt par une conjoncture politique favorable : celle, bien sûr, d’une campagne présidentielle américaine particulièrement mouvementée qui a fait remonter les scores d’audiences des jeunes jusqu’au Royaume-Uni (avec une consommation linéaire deux plus importante qu’en 2012). Des pics d’audience exceptionnels donc, qui rendent la comparaison avec les audiences de 2017 peu flatteuse – mais Deloitte prévoit que le recul de la TV devrait être à nouveau se stabiliser en 2018 et 2019.

 Les "nouveaux usages" arrivent eux aussi à saturation

Si la télévision traditionnelle est désertée par les plus jeunes, ce n’est pas (uniquement) à cause de ses programmes vieillissants – c’est surtout une conséquence de la concurrence des multiples autres usages qui se sont démocratisés ces dernières années : vidéo mobile, consommation en streaming ou sur des plateformes SVOD… Mais après les années fastes, ceux que l’on a longtemps appelé les « nouveaux usages » ne sont plus si nouveaux que ça et eux aussi approchent de la saturation, estime Deloitte.

mob

Côté conso mobile, le smartphone a en effet atteint un taux de pénétration qu’il lui sera difficile de dépasser, étant désormais possédé par 94% des jeunes Américains en 2016 (contre 55% en 2012), 95% au Royaume-Uni et 92% au Canada. Un taux record donc, avec un temps de consommation quotidien qui n’a fait qu’augmenter ces dernières années : de 90 mn par jour en 2015 aux US à… 156 mn par jour en 2017, soit une augmentation de 73%.

Une croissance qui s’explique aussi par l’augmentation substantielle de la taille des écrans depuis quelques années, qui a favorisé la consommation de vidéo sur mobile (passée de 4,6 mn par jour en 2015 à 11,9 mn par jour en 2017). Mais le temps libre des utilisateurs n’étant pas illimité (tout comme la taille de leurs mains et de leurs poches, d’ailleurs), la croissance de la taille des écrans mobiles et du temps passé dessus par les Millennials devrait être appelée à ralentir dans les années à venir, d’après Deloitte.

svod

Même tendance côté streaming et SVOD, des modes de consommation qui ont vu leurs usages exploser ces dernières années et dont la croissance devrait mécaniquement ralentir. Alors qu’entre 2012 et 2015, la part de 18-34 ans américains abonnés à Netflix a quasiment doublé en passant de 28% à 50%, il semble hautement improbable que ce chiffre double à nouveau d’ici 2020. Même logique sur la vidéo en streaming dont la consommation a tout simplement triplé en 3 ans (de 1.6 heures par semaine en 2016 à 5.7 heures par semaine en 2015) : la croissance de ce mode de visionnage devrait continuer mais à un rythme moins soutenu.

On l’aura compris : l’heure n’est plus au décrochage brutal des jeunes mais plutôt à un déclin lent (mais inexorable, il faut bien l’avouer) du petit écran. Pas question toutefois pour Deloitte de signer l’arrêt de mort de la télévision, dont certains programmes comme le sport ou la TV réalité continuent d’être plébiscités en consommation linéaire traditionnelle.

L’urgence, pour l’industrie de l’audiovisuel, est donc surtout d’adapter ses mesures d’audience pour parvenir à observer au plus près l’évolution des usages des publics (et pas seulement les jeunes), dans toutes leurs subtilités.
