Messaging, which allows to communicate in encrypted form, work with a protocol developed internally by mathematicians far from experts. A good reason not to use it for some specialists.
Pavel Durov, likes to tell it created Telegram to escape the supervision of the Russian government. Adorned with the prestigious Legend, the application promises its users seamless encryption of communications. Telegram but would not be so sure it as emphasized several US media including The Daily Dot and Gizmodo .
First problem: cats are not encrypted by default as WhatsApp or signal, used for example by Edward Snowden himself. You have to go to settings and make additional settings for that to be the case. That do not know many users believe converse discreetly. A boon for intelligence services or hackers.
MTProto, the mysterious house protocol
Worse, the founders of Telegram would not resume protocol WhatsApp or signal which have been proven. They preferred to use non-mathematicians experts in the field who have developed a protocol house, MTProto, which no one knows the algorithms. "Unless you have considerable experience in the field, nobody has to develop its own protocol. Nobody really understands why they did that " , told Gizmodo Professor at the University of Surrey Alan Woodward, a specialist in computer security.
Furthermore, Telegram has been leaked metadata earlier this year. A researcher had indeed realized that it was possible to understand when a user was online or offline.
The expert Thaddeus grugq has therefore engaged in a regular attack of the application on his blog : "Telegram is subject to bugs, works with encryption homemade fuiter has already voluminous metadata steals books to address and is now known to be a haven for terrorists. We could not do worse combination for secure messaging " , he asserts. He concluded: "For better protection, use anything" .
It would be better to use another application
Finally, leaders Telegram collaborate without being asked with governments or government agencies such as the FBI. It has long been the preferred mobile email jihadists, until a large number of their accounts to be deleted in the month of November under pressure from the international community. But the terrorists have once recreated.
Recall that to date still no evidence that the Telegram encryption keys were broken. So these are vis-à-vis safety recommendations of an application that inspires concern to experts because it was not developed by specialists.
The marketing of the tablet will cease at the end of the year, even though it is often already out of stock and the area 4 does not seem to point the tip of his nose.
In the US the tablet Surface 3 is hard to find for a few weeks which was beginning to talk high-tech sites. Microsoft breaks silence recognizing officially with the site ZDNET.com that cease marketing the product in the month December 2016. Microsoft's statement:
"Since the launch of the Surface 3 there over a year, we have seen strong demand and satisfaction of our customers. Inventory is limited now and by the end of December 2016, we do not produce more devices Surface 3 ".
No area 4 on the horizon
For now, not a word about his potential successor: Microsoft Surface 4. he would wait for this next major release of Windows 10. Will he wait until 2017 to find out more? Mystery.
Launched in spring 2015 at 719 euros with the OS Windows 8.1, this tablet hybrid that can turn into PC was designed as a more affordable version of the Surface Pro, but it also was fishing with his every performance. She would still have found its audience with students and families, according to Microsoft. Since then she has received updates of Windows 10 and the arrival of 4G.
Adding that the bracelet tracker activities would likely suffer the same fate.Already often out of stock, production is likely to cease in the coming months without being immediately replaced by another product.
Riding the wave of Euro 2016, fake ticket selling sites start appearing on the web, and mobile games that are biased to advertising.
Two big events happen in the world of football, first in the US with the Copa America Centenario (from 3 to 26 June), followed by France with the Euro 2016 Championship (June 10 to July 10 ). The fans and other fans will of course be at the rendezvous, but also scammers. Thus, the famous Avast antivirus editor published on his blog a series of recommendations to avoid being cheated.
Beware of counterfeit notes
Cybercriminals will first tackle the sale of tickets for the matches, which are now very difficult to obtain. They set up fake retail sites and launched campaigns on social networks (Facebook, Twitter) or by email to encourage fans to order. Their goal is to sell fake tickets and especially easily retrieve banking information of buyers (credit card number, PIN, etc.).
Thus, UEFA recommends that you buy tickets as among authorized dealers, for example ... on the UEFA website, offering the browser extension Brandsays to detect illegal sites. Caution also selling tickets whose prices seem too attractive.
Games invaded by advertising
Football fans want to watch the games, but also play on their smartphone or tablet. The best-known app is FIFA16, title developed by Electronic Arts. But Avast spotted four football games, three as name Soccer 2016 and the fourth is called Football 2016 to 2025. They just made their appearance on Google's application store and turn out to be scams.
Indeed, the player finds himself invaded by advertising when it attempts to start a game. The purpose of the developer, who designed the four games, is of course to make money with advertising. It is not illegal in itself, but it leads to totally unplayable games that do not keep their promises.
Avast does not mention it, but it is likely that fraudulent mails related to the two competitions will arrive soon in our inboxes with links or attachments in which it will not click above. It is also possible that telephone scams are multiplying. Digital hostilities have begun before June 10, and it is not safe unfortunately they stop on July 10 ...
TVs and 4K or OLED, video projectors, sound bars, mobile DTT tuners ... here is our selection of products not to miss anything of Euro 2016.
This will probably not escaped you - especially if you are fans of football - but the next European Cup will take place from 10 June to 10 July. And like every great sporting event, the temptation to change equipment or to expand its multimedia equipment is great.
It's not that miningjobsboard.com says, but the numbers of "cash out". According to GFK data we have procured, the TV market is exploding in recent months: + 337% in volume for the week of April 4 to 10 compared to last year over the same period. Clearly it is 269,000 pieces were sold in just one week. This huge increase is partly due, it is true, the "switch to DTT", which came under a standard HD MP4 since April 5.
The bellows is not completely fallen since. Growth is 60 to 80% per month, depending on the slab sizes. Manufacturers evoke this time renewing televisions to the approach of the Euro, which gives rise to also nice specials as you will see a little further.
But to have fun and follow the Euro, it's not just TV. Other facilities are envisaged, whether in the living room, with friends in the garden or just on the go. And to live at best the atmosphere of the stadium, it is also conceivable to push it a bit much volume? Again, we have solutions for you.
A wide choice of TV!
At half-time the last few games of football, in newsletters or resellers in your mailboxes, promotional offers on TVs abound.
We find it quite difficult to recommend a specific model as your constraints are many and varied (size, price, selection of techno, etc.). What we can however tell you is that to the delight of everyone, there is real business to be done.
The manufacturer Samsung is necessary also quite strongly by promotions.For example, a 32 inch Full HD curved slab (the UE32J6300 ) is in promotion now only 400 euros. An aesthetically successful model, but may be too small? Also from Samsung, the UE48J5000 , is a model 48 inches, or 120 cm diagonal, sold at 480 euros! A product that, given its size / price ratio is not expected to offer the best services at the time.
The other good news is that 4K is now accessible in pricing. At LG, the 43UF680V is a UHD TV connected to 43 inches that is less than 600 euros.But beware, the tests conducted by the lab olaisred.com show that it is not very relevant to invest in 4K TV small (under 55 inches) or first prize solely because they are compatible Ultra HD.
By doubling the bet, either from 1200 euros, you will have no trouble finding UHD TV 55 inches brands. It is also highly recommended, with this budget in hand, opt for models Sony, Panasonic, LG, Samsung or Philips (short of major brand), even a little trim on the diagonal. Models lesser known brands have indeed sometimes struggle to integrate a chip rather effective upscaling to display properly Freeview HD content on their UHD slabs.
If the connected TV's are trendy, try as much as possible in the store not to be surprised by too slow or too complex interface. Moreover, the approach of Euro 2016, do not neglect the recording functions on USB key ... always handy to watch a game missed during the day.
Think especially before any purchase to scrutinize well the rays of the store or the corner of the web pages to check if there is not a pending refund offer.Sony, for example, offers discounts of several hundred euros.
Finally, the most affluent can turn to exceptional TVs such as Sony 85XD8505(9890 euros), the LG 65G6V (8500 euros) for the new Signature range or thePanasonic TX-65CZ950 , a model sold 4K OLED 9990 euros.
To see the matches on giant screen
Between spend a lot in a huge TV or spend less than 1500 euros in a projector, the question may arise. It's certainly our view. Although the use and installation situations are not so simple, our recent tests have allowed us to identify excellent projectors sometimes sold less than 800 euros. This is the case of Viewsonic Pro7827HD and Epson EH-TW5350 two products tested, approved and highly recommended by the Editorial miningjobsboard.com
Movie fans will not be disappointed and will also look at the BenQ W2000(1200 euros) which offers an immense and sublime image. Other models are tested in our top 10 video projectors .
Improvise a large TV
In a completely different genre, you can also improvise you a large TV by adopting a mini projector. A product category that has few brands today, but where you will find the Philips PicoPix PPX4835 . The manufacturer offers this model with a small device equipped with a battery and an HDMI jack to broadcast all your great content.
The best promotions the place still to 422 euros. And if the solution you are interested, note that it does not include a digital tuner. It will either add one, or use the MHL compatibility of its HDMI jack for connecting a compatible smartphone. The latter will then be connected to a TV streaming service.
The atmosphere of the stadium seating
To live fully Euro it takes the picture ... but also the sound. Of course, to make noise, you can opt for a powerful home cinema. Be aware that for everyday use, there are solutions to smaller benefits, certainly, but also less expensive.Examples Sound Bar LG LAS260b (100 watts announced) and Yamaha YAS 105 (60 Watts announced) sold respectively 99 and 190 euros. The latter also currently enjoys an attractive discount on the retail price of 300 euros.
To further give a little more chest to the ambiance, offers the Samsung HW-K450, a kit comprising a soundbar and a subwoofer. It develops 300 watts power (announced) and Bluetooth compatibility also allows you to listen to music from your compatible devices. This solution is currently on sale for less than 280 euros. For more sensitive users to design, Cabasse also offers audio tray - understand that this is a forum on which we put the TV - for 499 euros. The Stream Base is his name, as discreet as it is still integrates 2 tweeters, 4 lower midrange and a way for serious, delivering a total of 120 watts and the promise of a 360-degree sound.
To follow the Euro anywhere
There is also Freeview tuners that do not impose to have an Internet connection or a handy antenna. Totally autonomous, they incorporate a battery, antenna and plug in either micro USB or HDMI. We find for example the Android TV PCTV 78E to 60 euros.
Otherwise, you will always have access to the shops online to a wide range of mobile TV, often in the form of a travel DVD player with integrated Freeview tuner. For them, the price starts at 130 euros.
Acer presents a new Chromebook has, on paper, an excellent up to 14 hours. If confirmed by our tests, this would make an interesting machine.
Five years after releasing his first Chromebook, Acer returns again to the charge with the Chromebook 14, a model that provides up to 14 hours of battery life.
This computer has a 14-inch IPS screen proposed two definitions: Full HD (1920x1080) or HD (1366x768). And it is precisely with this HD screen that the manufacturer claims a battery life of 14 hours, without specifying the capacity of the battery. With Full HD screen, it falls to 12 hours.
Also new, it has an all-aluminum chassis for lightness. It weighs only 1.55 kg for a thickness of just 17 mm according to Acer.
Inside, we find, depending on the model, a quad Celeron processor N3060 or a double heart, accompanied by 2 or 4 GB of RAM and 16 or 32GB of storage space. This Chromebook also comes with 100 GB of free storage on Google Drive so users can keep their carefree photos, documents and other files.
connectivity, the Chromebook 14 is provided with two USB 3.1, Bluetooth, Wi-Fi and an HDMI port. Webcam 720p (1280x720) offers a wide field of view, allowing you to frame several people in a video conference, for example.
The Acer Chromebook 14 will be available in the month of April from 249 euros. Pricing and equipment that make it an interesting alternative to the Chromebook 14 HP .
In the US, a company specialized in amicable settlements wants to set up a more aggressive system to encourage pirates to pay.
Six years after its creation, the Hadopi seems not really a deterrent vis-à-vis internet users illegally downloading movies. But if in France the warning is measured way, Americans can deal with agencies - private this time - much more aggressive. Recover money from those who do not respect thecopyright has even become a separate activity. And Rightscorp , one of the industry leaders, intends to take the browser users hostage to force them to pay.
Silver or trial
According to the website Torrent Freak , he would develop a system calledScalable Copyright that would send warnings as notifications on the browser.The goal is to avoid sending emails too often ignored at the firm taste. After a number of warnings, the browser would end completely blocked. Only solution out his credit card and pay tens of dollars.
In recent years, Rightscorp specialized in this field by sending threatening emails to those who have broken the law. The company has developed partnerships with many Internet Service Providers (ISPs) US to retrieve the names associated with IP addresses, as does the Hadopi in France with the support of the TMG business. Except that the tone is a bit edgier. To avoid being sued - and risk a fine of up to $ 150 000, the user is prompted to pay on the spot about thirty dollars. Part of the money is then paid to the beneficiaries.
A precedent in France
Unfortunately for Rightscorp, individuals do not easily give in to blackmail, probably aware that legal action would be too costly for the company. In 2015, the company has also accused a net loss of $ 3.5 million.
Developing Scalable Copyright sounds like a last attempt to extort money massively to users. But American ISP might not follow the lead of Rightscorp for fear of being perceived as too intrusive by their clients.
In France, such a system would be unlikely to emerge. In 2007, a French lawyer had itself tried to do so, asking 400 euros Internet users accused of having hacked the game Call of Juarez . She had been heavily condemned by the Council of the Paris Bar. Finally, the initiative looks Rightscorp especially a new confession of impotence against the piracy.
The QTE, short for quick time event is a phase of play that reduces the gameplay to its simplest expression. A button appears on the screen, it is necessary to press at the right time not to interrupt the drive. Popularized by Shenmue and Sword of the Berserk: Gut's rage in 1999, this type of action already existed. Unique gameplay mechanicsDragon's Lair was released in 1983, now located in the most games. Until overdose?
Used to make the player feel the tension in a particularly brutal action in God of War,the QTE can enhance immersion. Gears of War would it be the same without his duels with a chainsaw? The examples of this type m
issing and not in these games QTE fit naturally into the gameplay, since they are not prevailing. Conversely, their predominance in the introduction of Resident Evil 6 fails to revive the player's interest in scenes that are desperately short of pace. Worse, they literally crippling action.
But the QTE can be downright a distressing uselessness, and we really wonder what is going through your head developers of Blue Dragon, when they decided it would bludgeon the A button to Open ... doors dungeons! The principle of cinematic action of Final Fantasy XIII-2 is also questionable: after the attack on our successful character, why inflict handling more in order to conclude it also mention the case of Asura's Wrath where failure of a QTE has no influence on the drive, only the end of level score being modified.
However, there are modern games completely based on QTE, and we must say that their receptions diverge: while that Heavy Rain has divided the players, his critics accusing him of being a simple interactive movie where the life of a character was based only on a button at the right time, The Walking Dead won all the votes while offering a gameplay similar in its action phases. Fad or simple evolution of morals?
Still, the QTE divide. While the same difficulty of the current games divided updevelopers, more than ever it is time to ask whether the QTE really add value to Thurs or should we eliminate it in order not to fear the loss the gameplay it represents?
We know a little more about the avenues explored to develop the next mobile radio standard. The World Radiocommunication Conference held in late November adopted a roadmap for this.
This is a victory Bitter who managed mobile operators this November 27th.Even though they won some new frequencies, the World Radiocommunication Conference (WRC) has resulted in the maintenance in the state for at least eight more years, Ultra High Frequency (UHF) into the hands of terrestrial television.
Between 470 MHz and 694 MHz, this band was coveted by the telcos to boost 4G and have been useful to develop 5G. But the next standard of mobile broadband will have to do without. Options to make up for it are not lacking, however, validated by this same CMR and discussed at the conference organized by the ANFR this December 8 at Bercy.
"The 5G surely rely on a patchwork of frequencies", said Wladimir Bocquet, head of Spectrum Policy, GSMA, the global trade association for GSM operators. And it will pass first through the reallocation of existing frequencies, or the so-called practice of "refarming".
"Today, more than 60% connectivity even through 2G worldwide. In 2019, these 60% will switch to 4G or 4G +. This will free up frequencies ", further emphasizes Wladimir Bocquet. And actually, we already witnessing in France in 1800 MHz 4G reuse, while it was initially vested in the 2G.
A specter is best used
To increase the cellular network data transfer speed, all on a greater distance, a technique is studied closely by scientists for many years: the "massive MIMO" found sometimes also referred to by the term "smart antennas".Instead of relying only one antenna at the receiver and transmitter, it is to use several.
But these multiple entry and exit will not be without consequences, according to Olivier Huart, CEO of TDF. "This will pose constraints in terms of street furniture for local authorities and operators will also redesign the architecture of their mobile network", advance there.
Millimeter radio waves
Another way to dig, the rise in frequency. Mobile operators need more spectrum width to get more bandwidth. Between 500 MHz and 1 GHz in the ideal. Is very far above 20 MHz which is limited 4G. With more bandwidth, throughput would be higher in each radio cell.
Always at the last (CMR), operators have therefore advocated that in 2019, the frequency bands called "millimeter" lying beyond the 6 GHz are allocated to the 5G. Why beyond 6 GHz? Because the spectrum it offers the famous quality required bandwidth while being satisfactory spread.
A claim granted by the conference. She chose to study a frequency range between 24.25 and 86 GHz.
Experiments to 2020
We are now entering a phase of experimentation. Because this is to check whether the sharing of frequency bands mentioned possible, before retaining them as world standard. This particular will be the task of Orange as part of a European public-private partnership. The French operator is the first in France to have obtained authorization from ARCEP to test frequencies between 100 GHz and 6 in Belfort during the year 2016. The operator hopes to reach a theoretical speed 10-100 times that of 4G.
The frequency bands of the 5G will eventually identified at the next conference to be held in 2019. A life-size experiments will however be soon in 2018 at the Winter Olympics in South Korea, and in 2020 at the Summer Olympics in Japan.
Once the determined specifications, started to 5G networks should be made in France between 2020 and 2022. Yet he must have compatible smartphones. The 5G should therefore not be a reality for users before 2023, even if the operators and the European Commission always show the ambition of a commercial launch in 2020.
Wired magazine is almost certain: the creator of the digital currency called Craig Steven Wright, it is Australian and is 44 years old. A smart enough and crazy man for wearing only this revolutionary project.
Satoshi Nakamoto, the mysterious creator of Bitcoin, really be called Craig Steven Wright. A brilliant computer-graduate on the LinkedIn profile that dizzy,which hardly anyone had heard before Wired does today published an article demonstrating, with near certainty, that he is the creator of the famous digital currency. And blockchain, this great technology that could disrupt the economy by making it completely peer-to-peer.
Let's be frank: Wired is not 100% certain of having discovered the creator of Bitcoin. It must be said that many media who thought he discovered the anonymous genius, broke teeth. Newsweek relaunched the paper versionwith the (false) scoop. The New York Times was also his idea.
But the famous American magazine, if he takes tweezers, brings a number of clues and documents that nobody had met him before, elements that tend to show that its reporter Andy Greenberg and the enigmatic Gwern have beautiful Branwen and well solved one of the greatest mysteries of the decade geek.
A proper investigation of a detective novel
The investigation that led to the name of Steven Craig Wright takes almost the detective novel. Andy Greenberg went to bed with a security researcher, specialist in dark web, which responds to Celtic pseudonym Gwern Branwen.This magazine has provided several valuable documents that a "source close to Wright" was entrusted.
Wired does not publish, but first evokes a blog post published by Wright in August 2008-three months before the introduction of Bitcoin- in which he describes a scientific paper on "cryptomonnaies". More interestingly, another article in the same blog, dated November 2008, offers its readers to get in touch with its author via PGP encryption key associated with Satoshi Nakamoto ..., which published a few days before the famous article Bitcoin initiate the revolution.
A final paper (image below) shows a screenshot of the blog of January 10, 2009, which clearly indicates the direct involvement of Wright in Bitcoin. One can in particular read: "beta Bitcoin will be launched tomorrow. It is decentralized ... We will test until it works. "
The ultimate proof? Not so sure. First, because this message of January 10, while Bitcoin has already been launched. Wired tries to explain by jet lag, Wright living at the time in eastern Australia. But that's not all: this message was changed later ... then completely erased.
Fortunately, Wired has further evidence in his wallet. Branwen also provided the strength newspaper emails, accounting extracts and even Wright's mail to his lawyer, dating from June 2008, in which he imagines a "ledger distributed P2P." This is very similar to the ... blockchain, this database that lists all of the Bitcoin transactions.
But there is even better. Wright would have shared a lot of his project with a certain David Kleiman. Since deceased, the analyst would have founded with him a fund called "TulipTrust" on which have been handed ... the very first mined BTC. 1.1 million Bitcoin precisely. Equivalent, at current prices, over 420 million euros! A credible figure because it represents a huge visible on blockchain portfolio - which is public but anonymous, we remind you - usually attributed to Satoshi.
Wired still ahead of others rather convincing evidence, as the correspondence between Wright and the Australian Treasury, dating from 2014, in which our man advance the name of Satoshi Nakamoto to defend its arguments. "I did my best to hide the fact that I've been running Bitcoin since 2009, but I think everyone will end up knowing. "He says in particular.
Wright, a nerd who has staked everything on cryptomonnaies
The newspaper contacted Wright to try to confirm his information. He replied in a strange way, with an email address whose domain is "Tessier-Ashpool" the name of the company must hack Case, the hacker fantasy cyberpunk novel Neuromancer Willam Gibson. And IP address, from Panama, also corresponded to those used by Vistomail, a service previously used ... by Satoshi.
Wright responded to Wired by funny puzzles. "You dig, the question is: how deep are you located? "" You seem to know a few tricks. More than you should. " Or "There are too many to know secrets. The world does not need to know. No need to be a dictator to lead the change. ".
The man then simply stopped responding to the demands of the journalist.Just a few hours, it also closed one of its blogs and Twitter account, which was already protected.
According to documents recovered by the newspaper, the crazy low profile in any case correspond completely to that, dreamed, Satoshi. For in this decidedly amazing article, we also learn that Wright had three of its mortgaged properties and spent over a million dollars to invest in ... supercomputers. Tulip Trading, one of his companies, has also designed two machines that are classified in the famous top 500 of the most powerful computers in the world. Machines that it would have probably been used to create the first virtual coins.
So he is the creator of Bitcoin Wright? If Greenberg is not completely certain, it still indicates that, if this were not the case, Wright would have played him an incredible turn, developing a "hoax almost as ambitious as Bitcoin itself."We now strongly waiting for his reaction.
After the tablet surface and the Phone Book surface area could make an appearance next year.
The rumor around a Surface Phone is increasingly insistent. After supposedly benchmark results, here as other information seem to support the idea of the output of such a smartphone sometime in 2016.
According to the website Windows Central, after the abandonment of a first metal smartphone project, a brand new mobile is now in preparation. But unlike the previous one, it would be the baby of the team of Panos Panay, the man who created and area that surprised the high-tech world with the Living Book last few weeks. Panay would also be invested in the project so that the unit would be called "Panos's phone" within the company!
Intel also is part of: the foundry participate in the development of a chip for smartphones that would replace traditional Lumia Qualcomm processors.Chips that could help turn the traditional Windows applications ... and suddenly make this smartphone a real Pocket PC.
This smartphone could come out in the second half of 2016, estimates the US site, which will even forward two possible dates. The first would be an exit area Phone in August, parallel to the arrival of the next major version of Windows 10, Redstone.
The second option is an output during the fall. The arrival of the Surface phone would address while lower sales of other Microsoft smartphones, this date would have some sense if Microsoft decided to operate on an annual basis for its products area, a bit like its rivals Apple and Google.
