Bitcoin stabilises above $18k as mining difficulty increases

Bitcoin’s price has stabilised above the $18,000 region over the past few days, while the cryptocurrency mining difficulty continues to rise

Mining difficulty on the Bitcoin network is approaching a new high after rising by 8.9% over the past 24 hours. The Bitcoin (BTC) network’s hashrate is now above 130 EH/s. The data provided by on-chain analytics provider Glassnode revealed that mining difficulty is now less than 5% away from setting a new record.

Glassnode tweeted that “#Bitcoin mining difficulty increased by 8.9% today. It is now only 4.4% below its ATH.”

Bitcoin’s price surpassed the $19,000 mark for the first time in three years but dropped below $17,000 more than once within the week as bulls and bears struggle to control the market. However, the price is now up by more than 5% over the past 24 hours, and BTC is currently trading at $18,508.

The rise in mining difficulty has sparked enthusiasm within the cryptocurrency market as similar events marked previous bull cycles of 2013 and 2016. However, it is still unclear if the current bull run would set a new all-time high after Bitcoin came 3% closer to reaching its previous all-time high.

Although an increase in mining difficulty can be good for the cryptocurrency price, it is not a good sight for the users. An increase in mining difficulty implies increased fees for users and more time required to generate a block. This means that transaction time on the network would be longer, and there would be an increase in the number of unmined transactions in Bitcoin’s mempool.

Ethereum hashrate rising as developers ready Ethereum 2.0

The increase in mining difficulty isn’t restricted to the Bitcoin network. According to Glassnode, the Ethereum network set a new mining difficulty all-time high on 27 November. This saw the price of ETH decline from $600 to $513 within a few days. However, Ether is on the rise as it is currently up by more than 10% over the past 24 hours and trading at $587 per coin.

Ethereum’s increasing mining difficulty comes at a time when the network developers are getting ready to launch Ethereum 2.0. The launch of Ethereum 2.0 would see Ethereum switch to a Proof of Stake protocol rather than its current Proof of Work protocol. Mining difficulty would no longer be an issue as the network would involve staking the coins instead.

Denon Home 250 review: Save over £100 on Cyber Monday

Denon’s Home 250 is one of a trio of new multi-room wireless speakers from the Hi-Fi manufacturer, sitting alongside the smaller Denon Home 150 and larger Denon Home 350. With support for Spotify, Amazon Music HD, TuneIn, Deezer and more via Wi-Fi, plus AirPlay 2 and Bluetooth connectivity, it’s a versatile and excellent-sounding speaker that’s well worth considering if you can afford it.

What do you get for the money?

Measuring 295 x 216 x 120mm, the Home 250 is a fairly sizable unit. Beneath the grille are four separate drivers – two 19mm tweeters and two 100mm woofers – which are accompanied by a 133mm passive radiator. Each driver has its own dedicated class D amplifier and the speaker offers stereo playback, although this effect certainly won’t be as prominent as it might with a dedicated two-speaker Hi-Fi system.

As for its design, the Home 250 comes in either black or white and has an appealing, pared-down appearance. The speaker is covered by a water- and stain-resistant wraparound, meaning you should have no problems using it in your kitchen, and all controls are via a touch-sensitive panel on the top that lights up when you hover your hand over it. Here, you’ll find a play/pause button, volume controls and three quick-select buttons that let you quickly jump between different music sources.

Finally, the Denon Home 250 has built-in far-field microphones for detecting voice commands but with no support for Google Assistant or Alexa promised until later this year, these are effectively redundant at the time of writing. With no remote of any description, that means you’ll need to reach for your phone or get close enough to those aforementioned controls to change the volume or skip tracks.

What connectivity options does it have?

The Home 250 offers an impressive array of connectivity options. In addition to USB, 3.5mm and Ethernet ports, it delivers wireless music playback via Bluetooth and Apple Airplay. There’s also out-of-the-box support for Spotify Connect and you can stream thousands of different internet radio stations via TuneIn using the speaker’s accompanying Heos mobile app. Deezer, Amazon Music HD and Tidal are all supported too, and the speaker is able to stream other high-resolution formats, including 192kHz/24-bit FLAC, WAV, ALAC and DSD 2.8/5.6MHz files.

With no virtual assistant currently available, you’ll have to make do with linking Heos via the Alexa and Google Home mobile apps. However, it’s worth noting that this doesn’t always offer the same level of functionality as you’d get with a built-in voice assistant. In the case of Google Home, for instance, there’s no option to voice search for music using Google Assistant on your phone or other speakers, so you’ll have to make do with basic controls such as play, pause, skip and volume.

Rather frustratingly, there’s also no Google Cast option, so if you want to play radio from the BBC Sounds app, you’ll have to do so via the TuneIn option in the Heos mobile app or by connecting the Denon Home 250 to your phone via Bluetooth.

How easy is it to use?

Setup is very easy via the Heos mobile app (available for both Android and iOS devices), which guides you through the process. The app isn’t quite as refined or easy on the eye as I’d like – the settings menu in particular feels hidden away – but for the most part, it’s perfectly practical.

After you’ve added the Home 250 to your home Wi-Fi network, you can select the Music button to choose from a number of different services including TuneIn, Amazon Music, Deezer, Tidal and SoundCloud. From this menu there are also options to browse local music servers, along with the tracks on any USB storage device you might have connected or your phone.

Of course, if you’re mainly planning to use Spotify, the Home 250 is visible from the “Connect to a device” menu in the Spotify app as soon as you’ve added the speaker to your home network.

What’s the sound quality like?

Denon claims the Home 250 sounds best when placed 3 to 12 inches from a wall, as close to ear level as possible. There’s certainly truth in that; when placed in the middle of a room, music sounded much more boomy and the bass was less controlled. Ideally, though, a speaker this pricey would have adaptive room EQ, as found in Apple’s HomePod, the Amazon Echo Studio and Sonos Move.

Having said that, I found that the Denon Home 250 still offered a largely enjoyable listening experience at a range of volumes, wherever it’s placed. As you might hope for a speaker of its price, it has an excellent presence, especially in the lower frequencies, and I found it was able to comfortably fill my open-plan living area with sound. Mid-range frequencies, too, sound detailed and rich and there’s no unwanted distortion even when you turn the volume right up.

Treble is somewhat less prominent and, if anything, that adds to the overall pleasant, warm sound signature. Indeed, the speaker rarely sounds harsh in the way other single-unit speakers sometimes can. Should you want a brighter sound, you can easily adjust the equaliser to your own preference using the Heos app. It’s only a simple EQ with levels from -5 to 5 for treble and bass but that’s probably enough to overcome any problems you might have with the speaker sounding too boomy when placed in the middle of a room.

Should I buy it?

If the Denon Home 250 had launched with the integrated voice assistants promised for later this year, it’d be an emphatic yes. It’s a pricey speaker but the middle-sized Denon device offers superb connectivity and delivers a big, bold sound that can fill your home.

Without the voice assistant, though, there’s inevitably a temptation to look elsewhere. The Sonos Move, for instance, is a superb-sounding multi-room speaker that comes with support for both Alexa and Google Assistant. Best of all, though, it’s £50 cheaper.

Alternatively, if you’re an iPhone user, the Apple Home Pod has recently been slashed to just £200, meaning you could buy two, run them in stereo and still have change to spare. Sure, it lacks Google Assistant and Alexa but so does the Denon (and Siri is better than nothing).

It’s a shame really, because the Denon Home 250 doesn’t really do an awful lot wrong, but there are simply other products that do more for less. We’ll update this review when the firmware is released later this year, and I hope to be able to add another star.

Developer Hector Martin announces Patreon funding for bringing native Linux to M1 Macs

Apple recently introduced its first Macs with ARM processors and although they offer incredible performance, users cannot run Windows or Linux natively on these machines — at least for now. Popular developer Hector Martin today announced a Patreon funding to help him bring Linux to Apple Silicon Macs.

Hector Martin is a developer known for porting Linux to a variety of devices. Back in 2016, he announced a project that brought Linux with 3D acceleration to PlayStation 4. Now, Martin wants to make Linux run natively on new Macs with M1 chip — and possibly on any other Apple Silicon Mac.

As announced on his Twitter earlier today, he created a Patreon funding for those who want to support his work in porting Linux to Apple Silicon Macs. According to Martin, he wants to make Linux run on the M1 Macs with full performance rather than creating a “merely tech demo.”

Apple just released a new range of ARM-based Apple Silicon Macs that blow every other ARM machine in the same class out of the water. Wouldn’t it be nice if they could run Linux too? 
As it turns out, they can, but someone needs to do the work.

As he pointed out, running Linux on these ARM machines is not exactly difficult, but making it work properly with all Apple drivers, such as those required by Apple’s custom GPU, is complicated. Martin will first focus on making Linux work with dual-boot on the new M1 Mac mini, but later the project will also be updated with compatibility for other M1 Macs.

The project will be open-source and will be made available on GitHub. Users can help fund the project with donations of $3, $6, or $12 per month — and each level offers different benefits related to the project. The developer promises not to make any charges until he reaches $4,000 in contributions, which is how much he needs to guarantee his time investment to the project.

You can read more about Hector Martin’s project on the Patreon website.

Cyber Monday scams? Fakespot says it can identify fraudulent reviews and sellers online

The pandemic has made it all but impossible for a retail company without an online presence to survive. Yet while companies heavily dependent on foot traffic like J.Crew and Sur la Table have filed for bankruptcy this year, companies that are expert in e-commerce have thrived, including Target and Walmart. Amazon alone now attracts roughly one quarter of all dollars spent online by U.S. shoppers.

Unfortunately, as more shopping moves online, fraud is exploding, too. The problem is such that startups working with enterprises — flagging transactions for banks, for example — are raising buckets of funding. Meanwhile, one New York-based startup, Fakespot, is taking a different approach. It’s using AI to notify online shoppers when the products they’re looking to buy are fake listings or when reviews they’re reading on marketplaces like Amazon or eBay are a fiction.

We talked earlier today with Kuwaiti immigrant Saoud Khalifah about the four-year-old business, which got started in his dorm room after his own frustrating experience in trying to buy nutritional supplements from Amazon. After he’d nabbed his master’s degree in software engineering, he launched the company in earnest.

Like many other companies, Fakespot was originally focused on helping enterprise customers identify counterfeit outfits and fake reviews. When the pandemic struck, company spied an “opening crack on the internet,” as Khalifah describes it, and began instead catering directly to consumers who are increasingly using platforms that are struggling to keep up — and whose solutions are often more focused on protecting sellers from buyers and not the other way around.

The pivot seems to be working. Fakespot just closed on $4 million in Series A funding led by Bullpen Capital, which was joined by SRI Capital, Faith Capital and 500 Startups among others in a round that brings the company’s total funding to $7 million.

The company is gaining more attention from shoppers, too. Khalifah says that a Chrome browser extension introduced earlier this year has now been downloaded 300,000 times — and this on the heels of “millions of users” who have separately visited Fakespot’s site, typed in a URL of a product review, and through its “Fakespot analyzer,” been provided with free data to help inform their buying decisions.

Indeed, according to Khalifah, since Fakespot’s official founding it has amassed a database of more than 8 billion reviews — around 10 times as many as the popular travel site Tripadvisor — from which its AI has learned. He says the tech is sophisticated enough at this point to identify AI-generated text; as for the “lowest-hanging fruit,” he says it can easily spot when reviews or positive sentiments about a company are posted in an inorganic way, presumably published by click farms. (It also tracks fake upvotes.)

As for where shoppers can use the chrome extension, Fakespot currently scours all the largest marketplaces, including Amazon, eBay, Best Buy, Walmart, and Sephora. Soon, says Khalifah, users will also be able to use the technology to assess the quality of products being sold through Shopify, the software platform that is home to hundreds of thousands of online stores. (Last year, it surpassed eBay to become the No. 2 e-commerce destination in the U.S., according to Shopify.)

Right now, Fakespot is free to use, including because every review a consumer enters into its database helps train its AI further. Down the road, the company expects to make money by adding a suite of tools atop its free offering. It may also strike lead-generation deals with companies whose products and reviews it has already verified as real and truthful.

The question, of course, is how reliably the technology works in the meantime. While Khalifah understandably sings Fakespot’s praises, a visit to the Google Play store, for example, paints a mixed picture, with many enthusiastic reviews and some that are, well, less enthusiastic.

Khalifah readily concedes that Fakespot’s mobile apps need more attention, which he says they will receive. Though Fakespot has been focused predominately on the desktop experience, Khalifah notes that more than half of online shopping is expected to be conducted over mobile phones by some time next year, a shift that isn’t lost on him, even while it hinges a bit on the pandemic being brought effectively to an end (and consumers finding themselves on the run again).

Still, he says that “ironically, a lot of [bad] reviews are from sellers who are angry that we’ve given them F grades. They’re often mad that we revealed that their product is filled with fake reviews.”

As for how Fakespot moves past these to improve its own rating, Khalifah suggests that the best strategy is actually pretty simple.

“We hope we’ll have many more satisfied users,” he says, adding: “No one else really has consumers’ backs.”

Pocketnow Daily: Apple Will FINALLY Add THIS to the iPhone’s Camera?! (video)

Apple’s M1 MacBook Pro, Samsung Galaxy devices and more on Cyber Monday

Yes today is Cyber Monday, but since it’ll most likely be more like burned out Tuesday by the time you watch this video, we figured we’d get you deals that’ll still be available. Starting off with Samsung that has had a great holiday when it comes to deals. The Galaxy Z Fold 2 is still $999 if you have an eligible device for trade-in and now it gets sweeter as you get $100 in Samsung credit for accessories. The Z flip 5G is available for just $300, the Galaxy Note 20 Ultra is available for just $599 and the S20 Ultra for $789 so yeah, get the Note or that Z Flip 5G. The S20 FE is available for $189 on trade-in, but if you go to Amazon you can get it for $549 which is a cool $150 discount. Again, all of these deals are trade-in offers and you can get the $100 in Samsung credit. Moving on to the M1 MacBooks, B&H has the 13in MacBook Pro for $1199 which means you’re getting a $100 discount on the entry level variant. The MacBook Air is also $100 off, leaving that at $899. Finally, let’s talk Pixels as the Pixel 5 is $50 off, that leaves the Just Black variant for $649 shipped on Amazon. We have more deals on the Google Pixel 3a, other Samsung products, Intel Macs and more in the links in the description and even more at Pocketnow.com

M1 MacBook Pro with mini-LED display could launch sooner than expected

Moving on to rumors and Apple, there’s been a ton of reports for years that Apple is moving to miniLED but, with this latest batch of reports it looks like it’s finally becoming a thing. According to the latest DigiTimes report, Apple is set to launch the first miniLED iPad Pro in the first quarter of 2021 and they will starting mass producing the first MacBook Pro in Q2. Apple’s suppliers from Taiwan are actually happy as their momentum will be growing significantly once these orders come in. Of course, TSMC is also happy as well as, pretty much all of Apple’s products bring their silicon now. More importantly, this report goes along with Ming Chi Kuo’s report which we covered last week where he said we should expect that iPad in the first half of the year and we should get 16in and 14in MacBook Pros in the second half of the year. For those of you that don’t know, miniLEDs bring the similar benefits of OLEDs to LCDs while adding more power efficiency and a wider color gamut at the same time. So yeah, it might not necessarily be a good time to invest in anything, as miniLED could change more things for the better.

Samsung may have revealed what we’re getting in future Galaxy phones

Samsung Galaxy Z Fold 3 might cost the same as the Galaxy Z Fold 2

Back to Samsung let’s talk foldables as we got two different things to discuss. First off, Samsung Display’s blog posted two new sketches of devices that could actually become a real thing. The first one shows a tri-folding device both open and closed and the second one shows a rollable device that is being used more as a tablet than a smartphone with it bringing a sliding keyboard. And of course, Samsung is no stranger to doing these kinds of teasers but with them shifting their focus on to foldables, it’s interesting to see what they have in mind. Now, moving on to the real stuff, we have a new report that claims that the Galaxy Z Fold 3 will have the same price tag as the Z Fold 2 at around $2000. And, this is actually both good and bad. It’s good because we know that we’re getting more features like the S-Pen and better UTG, but it’s bad because this is supposed to replace the Note, and I doubt that it’ll work out for Samsung unless they bring the price tag down. Of course it’s too early to tell but, we’ll see if Samsung changes the price tag over time.

OnePlus 9 series will consist of not two but three phones

Let’s move on to OnePlus as, it looks like the company wants to keep expanding their line-up once we get the OnePlus 9. We have a new tweet and Voice post from Max Jambor where he gives us the new line up. Apparently it would consist of the OnePlus 9, the 9 Pro and a 9E. Now, of course, Max only tweeted out the names for it but in his voice post he said that it is yet to be seen if the OnePlus 9E will be a more powerful device than the regular 9 or a more budget-friendly offer like the Nord series. Now, we have some new renders for the Let’sGoDigital for both the 9 and the 9 Pro. We’ve already seen other renders before but these go further into which color variants we should expect. The regular line shows 4 different color variants which are the Green we got with the 8T, Gray, Blue and Black. As for the 9 Pro, these renders only show Onyx Black and Ultramarine Blue color variants like we got back with the 8 Pro. We’re expecting these phones mid-March, running on the latest Snapdragon chipset, at least 8GB of RAM and all the bells and

Apple zeroing in on suppliers to get periscope camera modules for upcoming iPhones

And finally, for the hottest news today let’s talk iPhones and their camera capabilities. If you haven’t watched our comparison with the Galaxy Note 20 Ultra, you should.. Cause that iPhone 12 Pro Max kind of won the camera section in everything but the zoom capabilities. Well, according to a new ETNews report, Apple is finally seeking an appropriate “folded” periscope camera solution for the iPhone and they have actually initiated discussions with suppliers. Now, this isn’t anything new as Apple has been filing patents on periscope lens systems since 2014 but they haven’t actually put one on the iPhone. Apparently Cupertino ran into some issues developing this technology as some of it was guarded by other patents. Some insiders also claim that there was a chance that Apple would purchase these from Samsung but, it’s actually pretty unlikely as Samsung would like to maintain a competitive advantage over Cupertino in this technology. If you’re asking when we should expect these, a report from Ming Chi Kuo earlier this year said that we should expect these to come with the 2022 iPhones with Sunny Optical and Semco supplying the components.

Slack could quickly become Salesforce’s golden goose

Last week, news broke that Salesforce was thought to be in advanced talks to acquire Slack. This inevitably fuelled much excitement and debate, not least because of the scale of the potential acquisition. Slack’s market capitalization was about $17 billion before the news broke and jumped to almost $23 billion soon after.

And with Saleforce’s earnings call scheduled for tomorrow, we could be in for an official announcement soon.

There’s no doubt this would be a major acquisition for Salesforce. It wouldn’t be its first of this scale — Salesforce acquired Tableau in 2019 for over $15 billion in an all-stock deal — but there would need to be a rock-solid argument for such a decision.

Why would Salesforce buy Slack?

To maintain the high rate of growth that it has achieved for the last few years, Salesforce has been investing in various initiatives that enable it to expand its reach in customer organizations. Some of this has been happening organically, for example improving its cross-selling and upselling within each customer. However, acquisitions have played a significant role here too.

Salesforce’s most recent acquisitions, MuleSoft and Tableau, were both designed to build out the Salesforce platform, enabling it not just to become embedded in CRM processes but to extend across customers’ entire operations. Despite these growth efforts, the bulk of Salesforce’s current applications portfolio doesn’t give it significant reach beyond sales and marketing teams.

The company wants its applications to be critical to every employee with an organization; to be the place they go to get their work done. And it has long been eyeing the collaboration software space as a way to achieve this.

It launched Salesforce Chatter in 2010, followed a couple of years later by Community Cloud, but neither really provided that extended reach outside sales. Salesforce’s $750 million acquisition of real-time document creation company Quip in 2016 was another step in this direction, but although the product has found a strong purpose in enabling work in the CRM environment, Quip hasn’t significantly expanded Salesforce’s reach.

Acquiring Slack, however, would finally give Salesforce the boost it’s been looking for. Although Slack was initially successful in tech-savvy IT teams, usage has spread significantly over the last couple of years — something that has accelerated dramatically with the increase in remote working due to the pandemic. The Slack team also has a good understanding of how to drive adoption and business change within customers, which would augment Salesforce’s customer success organization.

Plus Slack has made investments in areas that would be interesting to Salesforce. It has a large developer community, and is strong in bots and app development. And, much like Salesforce, Slack has been investing in low-code technology with its Workflow Builder tool, which enables individual, non-technical employees to automate day-to-day tasks. Finally, Slack Connect enables B2B collaboration and is gearing up to allow the creation of a B2B business network, which would be another great opportunity for Salesforce. Alongside Slack’s extensive list of customers, each of these areas provide differentiation and growth opportunity that could underpin a potential acquisition.

Why would Slack agree to a deal?

There have been rumors about tech companies wanting to acquire Slack for several years — arch-rival Microsoft was reportedly considering a purchase back in 2016 — for a much lower price, needless to say. However, the deal never came to anything. Microsoft decided to build its own competing solution, and Slack continued to grow at an astonishing pace.

Things are a bit different now.

Slack’s revenue growth has been starting to slow over the past 18 months, with its fiscal 2021 (which ends January 31) expected to show about 38% growth, versus 82% in fiscal 2019. It has seen a significant boost in 2020 in terms of adoption of the Slack application, with paid customers up 20,000 in the past six months, compared with an increase of 15,000 in the whole of 2019. Slack has also seen its number of large-ticket customers (with over $100,000 in trailing 12-month revenue) double since 2019.

Despite this, Slack has disappointed investors who were hoping for Zoom-like revenue growth in response to the pandemic. Although Slack and Zoom were the same size a year ago, Zoom is expecting to have grown 280% this year, dwarfing Slack’s 38% guidance.

Slack is also facing ever-stronger competition from Microsoft Teams. Slack still has some considerable points of differentiation over Teams, not least the two areas I highlighted above. But the effects of the pandemic and the shift to remote working have made the competition with Microsoft even tougher, especially given Microsoft Teams’ strength in video meetings, an area that has become business critical this year.

With strong ambitions, Slack now needs a way to step up its market reach and product investment, but doing that as an independent can be very challenging. Salesforce could provide a great platform for Slack and has plenty of experience and success in integrating major acquisitions, which would give Slack’s customers confidence if the purchase does go ahead.

If it does acquire Slack, Saleforce would likely continue to operate Slack as an independent business unit, in the same way it has done with Tableau or MuleSoft. An acquisition would inevitably mean much deeper integration across the breadth of Salesforce’s portfolio, which will only be positive for the many Slack customers that are already Salesforce customers. Slack already integrates with Salesforce in multiple ways, including with Sales Cloud and Service Cloud via Chatter, and with Quip for document collaboration. However, there’s scope for integration with the rest of the portfolio, and the Chatter capabilities could even be completely replaced by Slack.

An opportunity to team up against Microsoft

Overall, if they can agree on a deal, this could be a very positive and exciting move for both Slack and Salesforce, and one that would see them joining up against Microsoft — not just in business applications, where Microsoft is increasingly challenging Salesforce with its Dynamics 365 business, but in employee productivity and collaboration as well. One thing’s for sure, with such a big price tag, the pressure is on to make sure the impact on growth lives up to investors’ expectations.

Does Tor provide more benefit or harm? New paper says it depends

Does Tor provide more benefit or harm? New paper says it depends

The Tor anonymity network has generated controversy almost constantly since its inception almost two decades ago. Supporters say it’s a vital service for protecting online privacy and circumventing censorship, particularly in countries with poor human rights records. Critics, meanwhile, argue that Tor shields criminals distributing child-abuse images, trafficking in illegal drugs, and engaging in other illicit activities.

Researchers on Monday unveiled new estimates that attempt to measure the potential harms and benefits of Tor. They found that, worldwide, almost 7 percent of Tor users connect to hidden services, which the researchers contend are disproportionately more likely to offer illicit services or content compared with normal Internet sites. Connections to hidden services were significantly higher in countries rated as more politically “free” relative to those that are “partially free” or “not free.”

Licit versus illicit

Specifically, the fraction of Tor users globally accessing hidden sites is 6.7, a relatively small proportion. Those users, however, aren’t evenly distributed geographically. In countries with regimes rated “not free” by this scoring from an organization called Freedom House, access to hidden services was just 4.8 percent. In “free” countries, the proportion jumped to 7.8 percent.

Here’s a graph of the breakdown:

More politically “free” countries have higher proportions of Hidden Services traffic than is present in either “partially free” or “not free” nations. Each point indicates the average daily percentage of anonymous services accessed in a given country. The white regions represent the kernel density distributions for each ordinal category of political freedom (“free,” “partially free,” and “not free”

Each point indicates the average daily percentage of anonymous services accessed in a given country. The white regions represent the kernel density distributions for each ordinal category of political freedom (“free,” “partially free,” and “not free”

In a paper, the researchers wrote:

The Tor anonymity network can be used for both licit and illicit purposes. Our results provide a clear, if probabilistic, estimation of the extent to which users of Tor engage in either form of activity. Generally, users of Tor in politically “free” countries are significantly more likely to be using the network in likely illicit ways. A host of additional questions remain, given the anonymous nature of Tor and other similar systems such as I2P and Freenet. Our results narrowly suggest, however, users of Tor in more repressive “not free” regimes tend to be far more likely to venture via the Tor network to Clear Web content and so are comparatively less likely to be engaged in activities that would be widely deemed malicious.

The estimates are based on a sample comprising 1 percent of Tor entry nodes, which the researchers monitored from December 31, 2018, to August 18, 2019, with an interruption to data collection from May 4 to May 13. By analyzing directory lookups and other unique signatures in the traffic, the researchers distinguished when a Tor client was visiting normal Internet websites or anonymous (or Dark Web) services.

The researchers—from Virginia Tech in Blacksburg, Virginia; Skidmore College in Saratoga Springs, New York; and Cyber Espion in Portsmouth, United Kingdom—acknowledged that the estimates aren’t perfect, In part, that’s because the estimates are based on the unprovable assumption that the overwhelming majority of Dark Web sites provide illicit content or services.

The paper, however, argues that the findings can be useful for policymakers who are trying to gauge the benefits of Tor relative to the harms it creates. The researchers view the results through the lenses of the 2015 paper titled The Dark Web Dilemma: Tor, Anonymity and Online Policing and On Liberty, the essay published by English philosopher John Stuart Mill in 1859.

Dark Web dilemma

The researchers in Monday’s paper wrote:

These results have a number of consequences for research and policy. First, the results suggest that anonymity-granting technologies such as Tor present a clear public policy challenge and include clear political context and geographical components. This policy challenge is referred to in the literature as the “Dark Web dilemma.” At the root of the dilemma is the so-called “harm principle” proposed in On Liberty by John Stuart Mill. In this principle, it is morally permissible to undertake any action so long as it does not cause someone else harm.

The challenge of the Tor anonymity network, as intimated by its dual use nature, is that maximal policy solutions all promise to cause harm to some party. Leaving the Tor network up and free from law enforcement investigation is likely to lead to direct and indirect harms that result from the system being used by those engaged in child exploitation, drug exchange, and the sale of firearms, although these harms are of course highly heterogeneous in terms of their potential negative social impacts and some, such as personal drug use, might also have predominantly individual costs in some cases.

Conversely, simply working to shut down Tor would cause harm to dissidents and human rights activists, particularly, our results suggest, in more repressive, less politically free regimes where technological protections are often needed the most.

Our results showing the uneven distribution of likely licit and illicit users of Tor across countries also suggest that there may be a looming public policy conflagration on the horizon. The Tor network, for example, runs on ∼6,000–6,500 volunteer nodes. While these nodes are distributed across a number of countries, it is plausible that many of these infrastructural points cluster in politically free liberal democratic countries. Additionally, the Tor Project, which manages the code behind the network, is an incorporated not for profit in the United States and traces both its intellectual origins and a large portion of its financial resources to the US government.

In other words, much of the physical and protocol infrastructure of the Tor anonymity network is clustered disproportionately in free regimes, especially the United States. Linking this trend with a strict interpretation of our current results suggests that the harms from the Tor anonymity network cluster in free countries hosting the infrastructure of Tor and that the benefits cluster in disproportionately highly repressive regimes.

A “flawed” assumption

It didn’t take long for people behind the Tor Project to question the findings and the assumptions that led to them. In an email, Isabela Bagueros, executive director of the Tor Project, wrote:

The authors of this research paper have chosen to categorize all .onion sites and all traffic to these sites as “illicit” and all traffic on the “Clear Web” as ‘licit.’

This assumption is flawed. Many popular websites, tools, and services use onion services to offer privacy and censorship-circumvention benefits to their users. For example, Facebook offers an onion service. Global news organizations, including The New York Times, BBC, Deutsche Welle, Mada Masr, and Buzzfeed, offer onion services.

Whistleblowing platforms, filesharing tools, messaging apps, VPNs, browsers, email services, and free software projects also use onion services to offer privacy protections to their users, including Riseup, OnionShare, SecureDrop, GlobaLeaks, ProtonMail, Debian, Mullvad VPN, Ricochet Refresh, Briar, and Qubes OS.

(For even more examples, and quotes from website admins that use onion services on why they use Tor: https://blog.torproject.org/more-onions-end-of-campaign)

Writing off traffic to these widely-used sites and services as “illicit” is a generalization that demonizes people and organizations who choose technology that allows them to protect their privacy and circumvent censorship. In a world of increasing surveillance capitalism and internet censorship, online privacy is necessary for many of us to exercise our human rights to freely access information, share our ideas, and communicate with one another. Incorrectly identifying all onion service traffic as “illicit” harms the fight to protect encryption and benefits the powers that be that are trying to weaken or entirely outlaw strong privacy technology.

Secondly, we look forward to hearing the researchers describe their methodology in more detail, so the scientific community has the possibility to assess whether their approach is accurate and safe. The copy of the paper provided does not outline their methodology, so there is no way for the Tor Project or other researchers to assess the accuracy of their findings.

The paper is unlikely to convert Tor supporters to critics or vice versa. It does, however, provide a timely estimate of overall Tor usage and geographic breakdown that will be of interest to many policymakers.

Linux might come to M1 Macs with your help

Hector Martin (AKA marcan) wants to port a full, useful version of the Linux operating system to the new Macs running Apple Silicon, but he needs help.

He’s got the skills for it — he put Linux on a Playstation 4, for example. But the developer wants assistance from the public bringing the operating system to Macs running the new M1 processor. Not technical help, but financial contributions.

Apple recently began phasing out Intel processors on Macs, and introduced a trio of macOS computers running the M1 chip that Apple designed in-house. The processor pulls in some impressive benchmarks, so it’s hardly surprising Linux users want access to it.

Bringing Linux to M1 Macs is a herculean task

Martin is ambitious about the project. “The goal is to bring Linux support on Apple Silicon Macs to the point where it is not merely a tech demo, but is actually an OS you would want to use on a daily driver device,” he said.

But he’s realistic too. “Since these devices are brand new and bespoke silicon, porting Linux to run on them is a huge undertaking,” said Martin. “Well beyond a hobby project, it is a full-time job.”

And that’s why the developer is looking for enough contributors to total $4,000 a month. If/when he reaches that point, he’ll begin work porting Linux to the M1-based Mac mini. Martin is asking for monthly contributions on Patreon to support the project.

An ambitious project

Martin is confident Linux can be ported to Apple’s new processors. Cupertino does not block unsigned/custom kernels from booting on Apple Silicon Macs. And he’ll be reverse engineering Apple’s code, so the project won’t break any laws.

The plan is to support every M1 Mac, as well as future ones. But the project will take an enormous amount of work. “Running Linux on things is easy, but making it work well is hard,” notes Martin. “Drivers need to be written for all devices. The driver for the completely custom Apple GPU is the most complicated component, which is necessary to have a good desktop experience. Power management needs to work well too, for your battery life to be reasonable.”

The code he’s creating will be open. “All development will be in the open, pushed to GitHub regularly,” promises Martin.

And he developer points out he has the experience to make Linux run on M1 Macs. “I’ve been reverse engineering devices for over half of my life, since the early 2000s,” Martin says. In addition to porting Linux to the PS4, he did the same for the PS3. And he helped develop open software support for the Nintendo Wii as well.

Martin launched the Patreon project on Monday, November 30. Funding is at 90% on the first day.

Poco M3 can now be yours for just $129

Xiaomi’s recently independent sub-brand Poco unveiled the M3 last week, and during the event it was mentioned that the introductory price for the new smartphone would be $129. This is now live on GearBest, for the model with 64GB of storage. If you want double that, the price jumps to $149.

Both of these are limited time offers, ending in just over two days. So if you’re interested, make sure you buy soon, because after the flash sale ends, the price will be upped by $20, as already announced.

Poco M3 can now be yours for just $129

The Poco M3 is definitely a very intriguing device, with its price obviously being one of its main unique selling points, but there’s also the huge 6,000 mAh battery, the FHD+ screen and stereo speakers (neither of which is a given at this price point), the very decent SoC it uses (again, for the price), and much more.

Problems downloading Google apps on your Huawei smartphone? This is the reason – Thehour.com

If you recently released a Huawei brand smartphone , you may have a problem installing Google applications. The reason behind the new “failure” would be the fight that the United States government maintains against the Chinese multinational.

Last September, Huawei announced that its devices would no longer have Google services by default. Despite the decision, there were ways to download the tech giant’s apps, but now they are failing. In addition, it is possible that smartphones that already had Google installed also begin to present difficulties.

A Reddit user reported problems downloading the company’s apps on a Huawei device. The person had Google services on his computer, thanks to the methods that have emerged in recent months. Even so, in one of the latest updates to Google applications, it has been impossible to install the APKs manually.

The error that pops up is that the application is not compatible with the device’s CPU, something that had not been seen before on Huawei mobiles with Google services.

According to the media specialized in technology Gizchina, due to pressure from the US government, Google has blocked the possibility of installing its applications on Huawei mobiles. The measure would also apply to teams that have Google services thanks to the “trick”.

This is very bad news for users, as they could be without access to these applications. It only remains to wait for the conflict to be resolved after the results of the United States elections. Or, find a way to “circumvent” the system to install our favorite Google apps on any Huawei smartphone.

Washington state launches COVID-19 exposure notification app using Google and Apple technology – GeekWire

Images of the Android interface for the WA Notify app being released Monday.

Washington state unveiled a new app to inform residents if they’ve been exposed to someone diagnosed with COVID-19, as infection rates in the state soar to an average of 2,700 cases a day.

WA Notify, announced Monday morning, is a free app that uses technology developed through a joint effort by Apple and Google called the Exposure Notification System. The app takes advantage of low-energy Bluetooth signals emitted by smartphones to detect and remember interactions, allowing people to be notified if they’ve been in proximity to someone who later tests positive for COVID. It does not collect any personal information to identify app users or track their movements.

“It rapidly gets the information out to people who were close contacts to watch for symptoms, to make them aware of testing opportunities, to self-quarantine and if they’re infected, to isolate,” said Washington’s Secretary of Health Dr. John Wiesman.

Health officials are eager for a new tool to help curb COVID’s spread. In Western Washington, the number of new daily cases increased more than six-fold from September to November. A recent report from King County found that roughly one-third of people who tested positive for COVID hadn’t known that they’d been in contact with someone who was infected and were not linked to an outbreak event.

Officials say the app does not use GPS and won’t replace contact tracing or case investigations — work that has been overwhelmed in many areas due to the surge in cases. Local and state investigators will work in support of the app, and the state has hired more investigators, bringing the number to 700 workers.

Now the challenge is to make the public aware of the app and get them to install it. In states that have similar apps, adoption rates have been low and it’s unclear how much of a difference the technology will make.

But even less-than-widespread use will have benefits, health officials said. An academic study predicted that an adoption rate of 15% would still curb infections by 11% and deaths by 15%, said Lacy Fehrenbach, the state’s deputy secretary for COVID-19 response.

Here’s how WA Notify works.

  • Smartphones that are running WA Notify and have their Bluetooth turned on are continually sending and receiving signals from other phones. These signals are shared as a random code that frequently changes, and creates a log of other devices that they’ve been in proximity with.
  • If someone tests positive for COVID, a healthcare worker determines if that person is using WA Notify. If they are, the infected person receives a code that they enter into the app. That triggers a signal to other WA Notify users saying that they’ve potentially been exposed.
  • The WA Notify app is set to track the exposures that could lead to an infection, which is defined by the Centers for Disease Control and Prevention as coming within six feet of another person for a total of at least 15 minutes over the course of 24 hours.
  • The code is only sent to people who were in range during the time the infected person was potentially contagious, which is determined by case investigators.
  • The app does not identify either party or reveal where the exposure took place, including whether it was indoors and outdoors.
  • The person who receives a notification is asked to quarantine and get tested for COVID.

iPhone users can activate the tool by enabling Exposure Notifications in their Settings. Android users can download the Washington Exposure Notification app from the Google Play Store.

The app’s most important potential health benefit will be notifying people who interact anonymously in public spaces, on a bus or at a grocery story, for example, or when someone who is infected can’t remember all of the places they’ve been and people they’ve been near. Because the app doesn’t track people’s locations, it won’t help identify hot spots for transmission. It will also miss people who don’t have smartphones.

Back in April, digital contact tracing was tech’s much hyped solution for helping curb COVID. Seattle alone spawned multiple efforts, including CovidSafe, a collaboration between the University of Washington and Microsoft; NextTrace, an initiative connected to Seattle’s Fred Hutchinson Cancer Research Center; and COVID Trace, a project started by three Seattle engineers with prior experience at Moz, Google, Uber and elsewhere.

So why has it taken nearly eight months for a statewide app to get here?

While multiple projects launched in the spring, they weren’t immediately ready for widespread deployment. The technology initially announced by Apple and Google required states to build their own apps and handle the notifications. There was no federal leadership for digital notification, and states struggled to come up with their own solutions. In early September, the tech giants released an updated version of the app that was more plug-and-play ready, with the Association of Public Health Laboratories managing notifications.

Even as tech solutions improved, Washington still needed to move cautiously in order to protect privacy concerns and address equity issues, Wiesman said. This summer the state convened an oversight committee including security and civil liberties experts as well as leaders representing people of color and other communities who are disproportionately impacted by the virus.

With the committee’s approval, earlier this month officials opened a pilot test of WA Notify. Some 3,500 UW students, staff and faculty have been using the technology, and researchers report that the test run has gone smoothly.

As of last week, 17 U.S. states and territories were operating exposure notification programs. Washington as well as Colorado, Connecticut, Maryland and Washington, D.C. are running programs based on Exposure Notification Express. In September, California and Oregon announced that they would also pilot apps using the technology.

Custom-made apps are being used in Alabama, Delaware, Guam, Michigan, Minnesota, Nevada, New Jersey, New York, North Carolina, North Dakota, Pennsylvania, Virginia, Wyoming. Many of these apps still use elements of the Apple and Google system or work with the Association of Public Health Laboratories, which should allow for notifications to continue working when people move between states.

Nevada is using an app built by Seattle’s COVID Trace. It launched in August and incorporates Exposure Notification Express technology.

“In terms of privacy, what Apple and Google have provided is the gold standard,” said Dudley Carr, one of the COVID Trace founders.

Carr said the app is performing well. From anonymized data they know that each positive case is triggering two to three notifications. So far 100,000 people in the state of 3 million have installed the app; their goal is to triple or quadruple that number and interest is rising as case counts spike.

Washington this week is kicking off a $2 million marketing campaign to publicize WA Notify. Officials are tentatively planning to send push alerts to phones using both iPhone and Android operating systems that would encourage people to install the app. Whether they do or not is up to them.

Dell XPS 17 (2020) review: This great big magnificent laptop is discounted at Currys

The Dell XPS 17 is indicative of a slowly growing trend in the world of laptops. That is the return to popularity of the large-screened desktop replacement, after several years of absence.

Championed by machines like the LG Gram 17, the Razer Blade Pro 17in, the Apple MacBook Pro 16in – and now the Dell XPS 17 – this new genre eschews the chunky stylings of the deskbound monsters of old, shaving off pounds to deliver big on-screen space while maintaining the sleek chassis of modern laptops.

READ NEXT: The best laptops to buy today

Dell XPS 17 review: What you need to know

And so, while the Dell XPS 17 is certainly imposing when opened, its slimline body means it’ll still fit in most large laptop bags. It’s still quite heavy at 2.1kg, but it isn’t in the same league as most of the workstation or desktop replacements of yesteryear.

The laptop comes with a frankly enormous 17in display and, in typical XPS style, this delivers a mind-boggling 93.7% screen-to-chassis ratio. Essentially, the screen almost completely fills the lid leaving only very slim bezels surrounding it.

This large screen is available in either a non-touch 1,920 x 1,200 resolution or a UHD+ 3,840 x 2,400 touchscreen with support for Dolby Vision.

As you’d expect, the Dell XPS 17 is also available in a variety of different specifications. You can’t buy it with the latest 11th Gen Intel chips just yet but there’s a choice of 10th Gen Core i5, i7 and i9 CPUs, along with Intel UHD Graphics or discrete Nvidia GeForce GTX 1650 Ti (4GB GDDR6) or Nvidia GeForce RTX 2060 (6GB GDDR6) graphics.

Memory and storage configurations, meanwhile, run from the most basic 16GB to 64GB of RAM and 256GB to 2TB SSDs.

Dell XPS 17 review: Price and competition

The model Dell sent in for this review costs £2,649 and includes an octa-core Intel Core i7-10875H CPU, an Nvidia GeForce RTX 2060 GPU, 16GB of RAM and a 1TB PCIe SSD plus the 4K 3,840 x 2,600 touchscreen. It’s a configuration that sits roughly in the upper-middle range.

The most basic specification starts at a surprisingly reasonable £1,549; that gets you a non-touch 1080p display, a Core i5-10300H CPU, 16GB of RAM, a 256GB PCIe SSD and integrated Intel UHD Graphics.

The most expensive variant, meanwhile, costs £3,664 and includes an Intel Core i9-10885H CPU with 64GB of RAM, a 2TB PCIe SSD, Nvidia GeForce RTX 2060 graphics and the 3,840 x 2,600 touchscreen.

How does this stack up against the competition? It’s actually pretty good value when you look closely. On the Windows side of things, you can go for the LG Gram 17 (2020), which weighs even less than the Dell and costs significantly less, too, but employs the lower-power, much slower Core i7-1065G7 or Core i5-1035G7 CPUs.

The Apple MacBook Pro 16in is the more appropriate comparison, since it’s available with comparably powerful internals. Prices are higher than the Dell though, at £2,399, and are also higher, spec for spec – the equivalent to my review model in Apple trim will set you back £500 more at £2,899.

Then you have workstations or gaming machines like the Razer Blade Pro 17 (2020). The Razer is a great laptop and similarly slim and stylish but, again, there’s no cheaper spec version, with prices starting at £2,499 and rising to £3,700 for a model with an Intel Core i7-10875H, 4K 120Hz screen, 16GB of RAM and an Nvidia GeForce RTX 2080 Super GPU.

Dell XPS 17 review: Design and layout

The Dell XPS 17 certainly matches its rivals in terms of style. In fact, it’s very much like an XPS 13 in appearance, just much, much bigger. It has the same black carbon-fibre interior, gleaming “platinum” finish edges and matte silver exterior, as well as a similar wedge-shaped profile.

When the time comes to pack up for the day, at 374 x 248 x 19.5mm (WDH) you’ll be able to slip it into most large laptop bags without stretching them at the seams. However, at 2.1kg (plus 485g for the power brick) it’s not as light as it looks.

Build quality, on the other hand, is beyond reproach. With a stiff metal lid that feels strong enough to protect the screen from the worst possible mishaps and a rigid, unyielding base that provides a solid foundation for the keyboard and touchpad, the XPS 17 appears to be extremely well knitted together.

The ergonomics are pretty solid, too. The three-stage backlit keyboard is as comfortable as they come, with square, Scrabble-style keys and a quiet, crisp, well-damped action. The layout is largely sensible, too, the only cause for slight concern being that the fingerprint reader/power button nudges the Delete key inwards by a centimetre or so.

The touchpad is just as good. It’s absolutely huge, measuring 150 x 90mm and it works perfectly for both general mousing and multitouch gestures.

Meanwhile, the large, upward-firing speakers on either side of that keyboard deliver audio with enough body to convince you that you don’t need to wear headphones all day. Well, not for podcasts and video calls, anyway. I’m slightly less enamoured of the noisy 720p webcam, but it is at least Windows Hello compatible so you can use it to log in with your face.

There are some irritations. Despite all the acres of space around the edges, the selection of physical ports and connections is fairly limited. There’s a couple of Thunderbolt 3 USB-C connections on either side, a full-sized SD card slot, a 3.5mm headset jack and that’s your lot. There’s enough space for a legacy USB-A port or two as well as an HDMI output so why not include them?

READ NEXT: The best laptops to buy today

Dell XPS 17 review: Display quality

Largely, though, the XPS 17’s physicals are pretty sound and, if the lack of ports is a hard thing to swallow, you do have the recompense of that wonderfully large 17in screen. The display option on test here is the 3,840 x 2,600 IPS touchscreen and, while I can’t speak for the 1080p model, this one is a real beauty.

It’s a wide gamut screen that’s capable of producing 159.1% of the sRGB colour space, which is equivalent to 109.6% of Adobe RGB by volume. It reaches peak brightness of 503cd/m² and an astonishing contrast ratio of 1,901:1.

It has all the credentials of a top-class laptop display when measured it, too. Testing against AdobeRGB, since that’s the colour space the display has been calibrated to, the measured average Delta E colour difference figure reached as low as 1.29 in our tests, indicating this is a fabulous display for editing your high-resolution RAW photos on.

The one fly in the ointment is that, despite its Dolby Vision accreditation, you’re not really going to experience any kind of serious HDR effect when watching movies on the screen as there’s no kind of local dimming.

Another thing to note is that, when I first pulled the laptop from its box, I experienced the irritating dynamic brightness effect that has afflicted most Dell XPS laptops for the last few years. This is where the display brightens when there’s a lot of bright content on screen, and then darkens when there’s a lot of dark content.

A bit of fiddling with settings in the Intel Graphics Command Centre and a couple of reboots seemed to succeed in disabling this but there’s no obvious setting you need to flip – I just happened to stumble on a fix through trial and error.

Dell XPS 17 review: Performance and battery life

If that’s an irritating glitch, then thankfully performance is actually pretty darned good, which is what you’d expect from a laptop with Intel’s octa-core, HyperThreaded 2.3GHz Core i7-10875H onboard. Here, it’s backed up by 16GB of RAM and a 1TB PCIe SSD and the performance numbers are great – it’s slower than the MacBook Pro 16in with the 9th Gen, octa-core Core i9 but not by much.

Not only that, but it’s a halfway decent gaming machine, as the numbers returned in our usual gaming tests show, although it is slightly limiting that both the touch and non-touch screens are only 60Hz, restricting real frame rates to 60fps or below. 

Even battery life isn’t all that bad for a big machine such as this, with the Dell XPS 17 lasting 7hrs 47mins in our video rundown test with the brightness of the screen set to 170cd/m² and flight mode engaged. Looking at the graph below, you can see it bests the MacBook Pro 16in and the Razer Blade Pro in terms of stamina but falls behind the lighter LG Gram, which is understandable given that machine’s comparable lack of performance:

Dell XPS 17 review: Verdict

The Dell XPS 17 has its foibles, no doubt. It’s not as light as you might expect given its slim profile and I would have liked some more legacy ports, too.

However, in general, this is a very serious laptop at a seriously tempting price. It has a huge display that’s perfect for professional-level photo editing, it’s slim enough to drop into most 15in laptop bags and you can even play AAA games on it thanks to the Nvidia GeForce RTX 2060 GPU

All in all, it’s a worthy competitor to the MacBook Pro 16in for Windows 10 users, represents better value for money, and the fact you can buy even cheaper configurations is an added bonus.

MacBook Pro 16-Inch With 12-Core Apple M1X Processor Tipped – Gadgets 360

MacBook Pro 16-inch with Apple M1X processor has been tipped to be even faster than the current M1 processor. While Apple has not shared any information on a new 16-inch MacBook Pro or an M1X processor, a tipster claimed that the latter will debut with the larger MacBook Pro through a tweet from last weekend. The tipster also shared some details about the alleged M1X processor but also said that the name is not final as of yet. Apple launched the M1-powered MacBook Air, MacBook Pro, and Mac mini devices earlier this month and the new processor has been leaving its Intel counterparts in the dust.

The 16-inch MacBook Pro, as per an older tweet by known tipster LeaksApplePro, will come with the new Apple M1X processor that will be even more powerful than the current M1 present in the latest MacBook models. While the M1 features eight cores, the M1X is said to come with 12 cores out of which eight will be performance cores and 4 will be efficiency cores. The tipster adds that the MacBook Pro with M1X processor will be unveiled through a press release, but did not share a timeline for the same.

Apple’s 16-inch MacBook Pro is its top of the line laptop that can be equipped with an octa-core Intel Core i9 processor. It debuted in November last year and despite some thermal limitations, it was a powerful laptop. If the rumoured M1X-powered 16-inch MacBook Pro does exist, given the efficiency of the M1 processor in smaller sized laptops, the performance of the M1X with active cooling in a bigger size would be quite interesting to see. The tipster quotes a source, “if you think M1 is fast, you haven’t seen M1X.”

Earlier this month, it was reported that a 14-inch MacBook Pro laptop powered by the M1 processor could also launch next year.

The M1 powered MacBook laptops have been outperforming their Intel counterparts across benchmarks and there is no doubt the M1 processor if more efficient, though there is still some work to be done when it comes to app support.

MacBook Pro, MacBook Air, and Mac mini with Apple’s M1 processor were launched earlier this month with the same design as the previous generation Intel powered MacBook models. Last week, it was reported that the redesigned models with the M1 processor will debut in the second half of next year.

Anti-insomnia app gets FDA approval, but costs $899

We’ve recently seen a prescription-only PTSD Apple Watch app get FDA approval. The same has now happened for an iPhone-based anti-insomnia app – but it costs a cool $899!

The coronavirus crisis has accelerated work on app-based treatments for mental health conditions which have previously required prescription medications and/or in-person therapy sessions …

Business Insider reports.

The COVID-19 pandemic has exacerbated the US mental-health crisis, with apps like Calm and Headspace booming as people try to cope.

Now, a new cohort of apps are working to directly treat mental illness, rather than just help people get by.
Three such companies told Business Insider their programs can drive similar results as medication, and said they believe in-person therapy is outdated.

The Food and Drug Administration has in recent months moved to help these mental-health apps become more available.

Experts at the FDA, National Institute of Mental Health, and American Psychiatric Association told Business Insider that evidence indicates the apps work, and that regulators are frantically playing catch up.

COVID has increased the prevalence of mental illness symptoms, and driven demand for treatments which were struggling to keep pace even before the lockdowns.

US adults have shown three times as many symptoms of depression during the pandemic than the same period in 2019, researchers at Boston University found in September […]

Healthcare providers have also struggled to keep pace with the soaring rates of mental illness for years, with therapists oversubscribed and new antidepressants showing little improvement on their predecessors.

Apps can help, using an approach known as CBT.

Click Therapeutics, Pear Therapeutics, and Orexo are three companies currently leading the field in the digital-health space. All have developed software to treat mental illness with cognitive behavioral therapy (CBT).

Broadly, CBT helps people understand why they think and act the way they do, and helps them manage and change those habits through reflexive tasks.

But while the cost of app-based treatment compares favorably to conventional methods, it’s still not cheap. That’s because they can still involve a doctor monitoring the patient’s progress and symptoms, as is the case for the anti-insomnia app.

Pear is behind Somryst, the first app approved by the Food and Drug Administration to use CBT to treat insomnia. A nine-week course of treatment using Somryst costs $899.

However, it’s hoped that apps will make treatment significantly more accessible. The lengthy report, which is worth reading in full, says that 60% of adults diagnosed with a mental illness received no treatment, and many others don’t seek help in the first place, so their conditions go undiagnosed.
