Next, if you want to access this quantum processor, you have to sign up for an account. Which means you must reach this page…
…and fill out an invitation request. If you hear back from IBM, you’re in, presumably.IBM doesn’t get it. It’s not 2007 any more. The cloud today is on-demand computing, delivered virtually instantly at scale. You pick a username, you enter a password, you hand over your credit card number, you get into the service immediately. You start using it.Since when has invitation-only limited access to scientific experiments been the cloud? How exactly do you share a five-qubit processor at scale? It’s too bad Big Blue can’t ask its cloud chief technology officer: he left recently, along with other top-brass and all the staffers axed in an ongoing restructuring.Don’t ask Arvind Krishna, senior vice president and director of IBM Research, either. This moment represents the birth of quantum cloud computing, he said in a canned quote, again demonstrating that IBM Research has a totally different definition of the word cloud to Amazon, Google, and Microsoft.

It’s IBM Watson-as-a-service all over again. Can’t someone at SoftLayer or IBM Bluemix have a word?PR spin aside, you’re not going to rewrite textbooks with five qubits. In 2001, IBM scientists factored 15 into three times five using a seven-qubit processor. In 2013, physicists in China factored 143 using four qubits. In 2014, researchers were able to factor 291,311 using only 6 qubits. Your humble hack’s 2.2GHz Core i5 laptop was able to calculate it instantly: 523 times 557.

Classic computer bits are either one or zero; on or off; true or false. Quantum bits are either zero, one or a superposition of both. Quantum computers are expected to be able to process calculations far faster than classic binary bits by coupling this three-state capability with other quantum effects. It’s something that’s been promised for decades.Quantum computing has a long way to go. IBM reckons 50 qubits are needed to top the fastest known supercomputers of today, and 100 qubit CPUs should be possible in the next decade. IBM’s five qubit system is a fairly big hulking thing; the brains of the processor must be kept in a cryogenic dilution refrigerator to minimize the effects of heat and electromagnetic radiation.

Providing this kind of facility remotely to scientists is a nice gesture by IBM Research. Maybe one day it can scale. But dressing up this experimental technology right now as a quantum-computing-as-a-service free-for-all is absurd.One tech news site declared this morning: IBM just beat Google to a brand new type of computing. Swap computing for marketing and you’re on the right track. Brocade has reset Q2 revenue expectations lower, citing a weak SAN market and continued IP networking headwinds. Instead of revenues between $542m to $562m, it now expects them to be between $518m to $528m. This is $523m at the mid-point, 4.4 per cent down on a year ago. CEO Lloyd Carney talked of a general softness in IT spending. William Blair analyst Jason Ader said: We suspect that weak systems sales, as well as a general shift to IP connectivity in storage, may have finally caught up to Brocade’s FC networking business. To a lesser extent, Brocade may also be suffering from customers waiting for the next product cycle (32 Gbit/s), which is expected to kick in toward the end of the calendar year. Full results are expected on 19 May. WAHckon University students in the Australian city of Perth have landed in hot water, with one charged by Police, after finding and exploiting severe holes to rewind travel charges incurred using the city’s SmartRider public transport smart card.

The Murdoch University students reported the flaws to SmartRider operator TransPerth and inflicted what is estimated to be about $18 in losses which were covered in later balance recharges, however local authorities considered the university security research an act of fraud.One student is appealing a conviction while a second involved only in the earlier parts of the research effort was not charged.Murdoch University second year student Jack Carruthers pled guilty and was handed a spent conviction, a type of criminal conviction that does not result in a permanent record that will show up in background checks.Carruthers and his colleagues undertook the research as part of their university security club Hack The Planet. Carruthers is the club’s president.Members exploited the identified flaws in an effort to demonstrate the vulnerabilities at Perth train stations, in the knowledge that the act could see them breach state laws.Carruthers and his fellow researchers found still-existing failings in the MIFARE Classic SmartRider system that allowed them to roll-back charges to cards enabling free travel.

It is possible to replay an autoload (direct debit recharge) and keep getting more credit, Carruthers told the WAHckon security conference in Perth, last Sunday.The costs came out to $18 and the smart riders had $20 worth of credit, so I thought we were in the clear but the judge was of the opinion that my damning confession was all that was needed.Officers showed up on Carruthers’ door about two months later, taking his laptop and ‘all of his clothes’ to prove his was the individual captured in CCTV photos.The researchers say the project was documented as part of the hacking club in what could conceivably demonstrate the academic intention of the work.The conviction comes at a time when the Turnbull Government under its Cyber Security Strategy is spending big to in part help lure and train students to information security university courses.Carruthers says TransPerth is planning a fix but will likely must invest in an expensive upgrade of cards to systems including the more secure MiFare DESfire EV2.He says the agency says it will remain vigilant for possible reload attacks until the upgrade.MIFARE Classic is long known to be vulnerable to compromise. The Christchurch bus system which then operated the platform was popped in similar 2013 research by Melbourne security bod William Turner who found he could load cards with any amount of money.

It was told to implement training and guidance or face court action following a data breach that led to a child’s medical reports being stolen.The council just west of Glasgow has been audited twice in 2013 and advised to improve its data-handling. It failed to do so, and in 2014 an employee left a laptop and paperwork on an adoption case in a car overnight, from which it was stolen.Ken Macdonald, assistant information commissioner for Scotland, said: “Let’s be clear, what we’re asking for here is a basic requirement for an organisation that is trusted with large amounts of local people’s personal data.” When is ad-blocking ethical? How about when the adtech industry is behaving so unethically it destroys people’s livelihoods?Musician and music rights campaigner David Lowery last year made the incendiary suggestion that musicians should encourage their fans to block the advertising running on music-streaming sites – even though in the short term, it’s the musicians themselves who’ll take a hit in income. With the rise in ad-blockers, his idea is topical again, so let’s have a look at the merits of the argument.

What does this mean? The NTIA isn’t sure beyond the fact that something clearly needs to be done. It points out that its analysis has only scratched the surface but even that initial review has made it clear that policymakers need to develop a better understanding of mistrust in the privacy and security of the Internet and the resulting chilling effects.It warns, not without some justification, that unless something is done to increase trust it may reduce economic activity and hamper the free exchange of ideas online.There are some policy plans afoot: the Obama Administration has put out draft privacy legislation, and the NTIA is running a number of processes with a range of stakeholders on online privacy and cybersecurity, including its current one on the internet of things.The release of this data however demonstrates that there is a very real impact of security and privacy breaches. And it blows apart the idea that a move to online activities is somehow inevitable by showing that people do in fact scale back when impacted. That reality may serve as a catalyst for businesses to get serious about fixing problems and invest in make the online experience a safe, more secure one. Students who have access to computer devices in the classroom do significantly worse than colleagues without them, a study has found.

In a study by MIT’s School Effectiveness & Inequality Initiative, titled The Impact of Computer Usage on Academic Performance: Evidence from a Randomized Trial at the United States Military Academy, students whose classroom access to computer devices was prohibited performed better in exams.726 undergraduates studying an introductory economics course at the United States Military Academy were randomly separated into three groups.A control group was prohibited from using any laptops or tablets, another had access to tablets which were required to be flat on the table at all times, while the third was free to use tablets and laptops.The researchers found that permitting computers or laptops in a classroom lowers overall exam grades by around one-fifth of a standard deviation.The reasons for this were unclear, however, as a number of factors could potentially contribute to the lower scores, including the ease at which students could be distracted by surfing the internet, lowered note-taking skills, and changes in the teacher’s behaviour when interacting with students on a computer.We want to be clear that we cannot relate our results to a class where the laptop or tablet is used deliberately in classroom instruction, as these exercises may boost a student’s ability to retain the material . Rather, our results relate only to classes where students have the option to use computer devices to take notes.
We further cannot test whether the laptop or ta blet leads to worse note taking, whether the increased availability of distractions for computer users (email, facebook, twitter, news, other classes, etc.) leads to lower grades , or whether professors teach differently when students are on their computers.

They conclude: Given the magnitude of our results , and the increasing emphasis of using technology in the classroom, additional research aimed at distinguishing between these channels is clearly warranted. Fluent, founded in May 2015 and now with $2.5m to its name, will use the new cash injection to expand its engineering team and expand sales.

Google has decided that emoji need to offer better role models for women and has therefore proposed 13 new ones, all depicting women in the workplace.Google’s proposal (PDF) says the company “wants to increase the representation of women in emoji” and therefore suggests “a new set of emoji that represents a wide range of professions for women and men with a goal of highlighting the diversity of women’s careers and empowering girls everywhere.”

Google’s four submitters cite a New York Times op-ed by Amy Butcher in which she wrote “How was there space for both a bento box and a single fried coconut shrimp, and yet women were restricted to a smattering of tired, beauty-centric roles? This was not a problem for our male emoji brethren. Men were serving on the police force, working construction and being Santa. Meanwhile, on our phones, it was Saturday at the Mall of America — women shopping while men wrote the checks.”The four Googlers also point out various studies that show women are the main users of emoji, so surely deserve emoji that go beyond cliches.The thirteen chosen emoji are also based on research into the most common occupations and take into account recent campaigns encouraging women and girls into professions in which they are under-represented.Emoji usually have secondary representations, but Google argues its 13 proposed characters should be depicted as women only because that’s the point of this whole idea.The proposal ends with a call for “other members of Unicode to join us in creating a system of emoji design that can accommodate a broader gender spectrum.” Under the deal it will provide communications in remote areas and additional network resilience. Mansoor Hanif, director of Radio Access Networks at EE, said the deal will enable the biz to deliver a truly nationwide 4G network to rural areas.

BlackHat Asia A world-first proof-of-concept worm – if unleashed – could spell disaster for the world’s critical infrastructure, including power utilities by making attacks exponentially more difficult to detect and stop.It is a stand-alone attack but The Register has confirmed a realistic stealthy end-to-end attack scenario can be produced by combining two independent research efforts.The programmable logic controller (PLC) worm is the brain child of German hackers Ralf Spenneberg and Maik Brüggeman of Steinfurt-based consultancy OpenSource Security Ralf Spenneberg, and, unlike any past attacks, is able to spread from devices without the need of an infected laptop or desktop.All other PLC malware such as Stuxnet relied on having an infected computer to spread to other controllers, meaning an infection could be stopped from proliferating by removing those machines.Spenneberg and Brüggeman claim the attack spreads like cancer between default Siemens S7 1200 PLCs, and could be reworked to target other systems.They say it can also be used in proxy-chains to gain a foothold into utility networks, depending on the PLC used.

Vous pourrez acheter l’iPhone 7 si vous pouvez tolérer la problématique des écouteurs, surtout si vous êtes du genre à changer d’iPhone chaque année, dès lors que vous en avez les moyens.Mais, en dépit des améliorations incontestables, ce nouvel iPhone n’est tout simplement pas aussi convaincant que beaucoup de ses prédécesseurs. Certains pourraient vouloir attendre un an pour le prochain opus — et peut-être une meilleure solution audio pour démarrer.
The Verge : "Attendez l’iPhone de l’année prochaine"The Verge : « Attendez l’iPhone de l’année prochaine »
Vous l’aurez compris, si certains pensent que passer à l’iPhone 7 est une excellente chose, d’autres suggèrent d’attendre l’année prochaine, pour un iPhone qui fêtera son 10e anniversaire. On s’attend à de belles choses. On se retrouve donc l’année prochaine à la même date ?En juillet dernier, nous avons entendu dire que la mise à jour d’anniversaire pour Windows 10, « Anniversary Update », serait déployée progressivement, étape par étape, et arriverait par vagues. La firme de Redmond avait alors mentionné que cela « prendrait un certain temps ». Mais, nous n’avions pas anticipé sur la notion « d’un certain temps ».

La déclaration de Dona Sarkar à l’époque ne voulait pas dire que tout le monde n’aura pas la mise à jour durant la première ou la deuxième semaine, mais en fait, que chaque PC recevrait celle-ci en août, voir en septembre pour les plus malchanceux. Mais, certaines personnes ne l’ont pas encore, elles ne l’auront peut-être pas avant fin septembre, voir octobre.Selon de nouveaux détails découverts par ZDNet, Windows 10 Anniversary Update pourrait arriver que début novembre pour ceux qui ne l’ont toujours pas.Dans un e-mail, Microsoft a déclaré : « la mise à jour anniversaire va se télécharger et s’installer par Windows Update. Le téléchargement se fera automatiquement, dès le début du déploiement le 2 août 2016. Ce processus pourra prendre jusqu’à 3 mois pour atteindre tous les utilisateurs… »Windows 10 Anniversary Update est déployée très très lentementWindows 10 Anniversary Update est déployée très très lentement
Bien sûr, il y a un côté positif à avoir à attendre si longtemps. En effet, les adopteurs précoces, ceux ayant déjà la mise à jour, ont trouvé quelques défauts assez désagréables, et ceux-ci ont été rafistolés petit à petit. Un bon exemple est le bug qui entraînait divers freezes du PC. De plus, les problèmes de webcam devraient également être résolus avec un patch ce mois-ci.

En effet, comme le note ZDNet, une partie de la raison de la lenteur du déploiement est que Microsoft peut suivre les progrès et les bugs, et ainsi prendre des mesures appropriées avec les différents retours. Cependant, espérons que la longue attente soit vécue par une très petite minorité d’utilisateurs, peut-être ceux fonctionnant sous Windows 10 sur des appareils moins courants.Pour ceux qui restent impatients, les clients de Windows 10 peuvent manuellement lancer la mise à jour en allant sur la page de téléchargement de Windows 10 et en cliquant sur le grand bouton bleu « Mettre à jour maintenant ». Cela permet de lancer l’assistant de mise à niveau de Windows 10 qui va télécharger les fichiers en arrière-plan, et permettre à l’utilisateur de choisir quand mettre à niveau le périphérique.L’un des éléments clés et peut-être le plus discuté sur l’iPhone 7 est le retrait de la prise casque de 3,5 mm, comptant plutôt sur le port Lightning ou des casques sans fil. Et, il semble que Samsung pourrait projeter quelque chose de similaire dans un proche avenir.

Deux sources « impliquées dans la chaîne d’approvisionnement des smartphones de Samsung » ont évoqué le sujet à Digital Music News, rapportant que Samsung, aux côtés d’autres fabricants Android, pourrait non seulement opter pour une prise casque propriétaire, mais également bloquer l’octroi de licences à Apple.Si cela est vrai, cela pourrait être considéré comme un geste de vengeance par la communauté Android, et pourrait forcer les fabricants de casques à choisir leur camp. Et avec plus de dispositifs Android que de iDevices, Samsung pourrait bien avoir la priorité.Ce serait de mauvaises nouvelles pour Apple et de mauvaises nouvelles pour tous ceux qui utilisent les deux mondes, à savoir iOS et Android, car cela pourrait forcer l’utilisation d’adaptateurs.When you’re trying super hard to make the relationship work pic.twitter.com/Ro3H1DgOC9Mais le choix ne serait pas une mauvaise chose. Alors que le choix d’Apple pour un port propriétaire peut provoquer la colère des fabricants Android, on peut légitimement penser que le retrait du port de 3,5 mm est une bonne chose. Celui-ci permet d’économiser un précieux espace, et les nouvelles technologies peuvent potentiellement offrir une plus grande qualité sonore.

En fait, l’une des sources affirme que Samsung vise à améliorer la qualité du son avec un nouveau port casque. Quoi qu’il en soit, la solution envisagée par Samsung ne devrait pas poser trop de problèmes pour tous ceux qui sont habitués aux dispositifs Android, puisque la prise exclusive de Samsung sera apparemment conçue avec tous les fabricants Android autour de la table, en leur offrant des licences peu chères ou gratuites.DonglesSoit un adaptateur, soit du Bluetooth ! Faites votre choix…
Mais, cela pourrait fragmenter davantage l’industrie du casque, et faire de l’audio sans-fil une option beaucoup plus attrayante – libérant les utilisateurs de, non seulement fils, mais également des ports propriétaires.Pour l’instant, bien que ce soit tout juste une rumeur, et alors que les jours du port jack 3,5 mm sont probablement comptés, il est trop tôt pour dire exactement quand ou comment il sera abandonné. Étant donné tous les tracas impliquant le remplacement de la prise casque, il semble très peu probable que le changement arrivera bientôt.
