One way to cool your massive bitcoin mining rig? Submerge it in oil

There is something about the prospect of making some serious loot that brings out the innovation in folks. With this entrepreneurial spirit coursing through their veins one smart team of bitcoin miners has built a $120,000 mining rig with a somewhat unorthodox twist: It’s submerged in a vat of cooling oil.

Due to the high temperatures created by the hardware used for mining cryptocurrencies, this 36 ASICs (application-specific integrated circuit chips) rig protects its valuable chips by rapidly dispersing the heat.

“Having been into mining for a while, we were dreading the arrival of summer as cooling becomes more of an issue than usual, forcing us to build all the cooling systems in our mines to withstand the hottest week of the year,” Alexander Aksenov, one of the brains behind the project, told Digital Trends. “Facing high [capital expenditure] costs for autonomous air-cooled systems, my partner Mirian and I began exploring alternative methods of achieving stable temperatures, taking as a benchmark the cost of a quality automated ventilation system.

“Having reviewed numerous immersion-cooled solutions that could be adapted to our needs,” he continued, “we came to the conclusion that the market is oversaturated with high-quality overpriced products that serve a purpose when financially subsidized, but are not viable for mining adaptation due to high costs severely affecting [return-on-investment] periods. That is when we made the decision to create an immersion-cooled solution from the ground up, which will be completely self-sufficient and autonomous from surrounding infrastructure.”

The system they built is able to cool up to 72 kilowatts of heat, coming ready with a full fuse box, Ethernet switch, and Zabbix-based monitoring system attached to it. It can be set up in any household or industrial space that meets the power requirements and has running water for keeping the oil appropriately chilled. As Alexander says, the byproduct of this system is hot water, which leaves the plated heat exchanger at a temperature of around 50 degrees — allowing them to heat the surrounding building and even provide enough hot running water to take showers.

The setup is located in Russia, where the pair of cryptocurrency masterminds have been working on their innovation lab since leaving previous jobs in the financial sector. “Cryptocurrency revealed to be the perfect platform for an exciting new direction with tremendous potential for growth that provides life-changing digital solutions, so we gathered our savings, converted them into crypto, quit our jobs and never looked back,” Aksenov told us.

At present, he said that the pair is working on a brand new immersion-cooled concept, although no further details are ready to be shared.

The only thing about this that sucks? That the pair is no longer working in conventional finance. After all, these kind of out-of-the-box thinkers are exactly what the financial system needs. Still, finance’s loss is cryptocurrency’s (and, presumably, this pair’s) gain.

Here are five features we’d like to see on the Samsung Galaxy S9

With just a few weeks until Mobile World Congress 2018, rumors about the next generation of smartphones are at a fever-pitch. While some manufacturers are choosing to skip major smartphone launches at the annual trade show this year, Samsung is returning to make a splashy debut for the Galaxy S9. As one of the most highly-anticipated phones of 2018, the Galaxy S9 needs to wow us. Here are a few features we’d like to see on the upcoming flagship.

A game-changing camera

Although the camera on the Galaxy S8 is great, it was quickly eclipsed by the iPhone X, the Google Pixel 2, the HTC U11, and even the Galaxy Note 8. We have a hunch Samsung will incorporate the best elements of the Note 8’s camera into the S9, and while there’s no way to confirm this yet, it’s clear the camera is the highlight of the phone. The invitation to its upcoming Unpacked event at MWC has a tagline that reads, “The Camera. Reimagined.”

This year we’re expecting to see at least one of the new Galaxy S9 models feature a dual camera array. We’re also expecting a huge improvement in low-light photographs with Samsung’s new Isocell image sensor on board, and we’re excited to potentially see a “Super Slo-mo” mode that will shoot Full HD video at 460 frames per second. We hope any of these improvements will hold up throughout the year when the S8 will inevitably face stiff competition.

Facial recognition

Face ID is a big deal for smartphones. Yes, Apple’s unlocking system on the iPhone X is hardly a new technology — Android devices have utilized facial unlocking systems for quite some time, but they were never as secure. Well, Samsung may be ready to go head-to-head with Apple with an awesome face unlock feature.

Galaxy S9 rumors point to a new feature called Intelligent Scan, which combines iris and facial recognition to create a more secure authentication system. While it’s sure to be a definite improvement, we’re still not sure if it’s going to offer the same level of protection as Face ID. What we really want is this system to be reliable, and better utilized in third-party apps. If secure facial recognition exists on the Galaxy S9, you should be able to use it to authenticate and open your Chase Bank app, just like you can with Face ID. Even better, Samsung may be keeping the fingerprint sensor on the S9, and it’s always great to give users a choice in case they do not want to use the facial recognition method.

Stereo speakers

Samsung needs to up its audio game with the Galaxy S9, especially since Samsung’s acquisition of Harman was completed early in 2017. The Galaxy S8 only has a single bottom-firing speaker, and it’s easy to cover it up with your hand when holding the phone in landscape mode. Leaked images of the S9’s packaging indicate we may see stereo speakers tuned by Harman’s AKG — finally some good audio to pair with a beautiful screen. Still, it doesn’t look like these speakers will be front-facing, which is disappointing. We’ll have to wait and see.

We’d also be very happy if Samsung kept the headphone jack, because wireless earbuds are still far from perfect.

A better battery

Evan Blass

After Samsung’s disastrous battery incidents with the Note 7, the company really seemed to get its act together with the Galaxy S8 models and even the Note 8. Last year’s flagships featured meaty batteries that last a full day without charging. But after using smartphones like the Huawei Mate 10 Pro and the Razer Phone, we want to see a 4,000mAh battery in the Galaxy S9 so we don’t have to deal with battery anxiety.

Storage options

dbrand

While most of the major flagships in 2017 offered a 64GB and 128GB storage model in 2017, the Galaxy S8 only came with 64GB (in the U.S.). We’re hoping to see Samsung join the ranks of Apple and offer the Galaxy S9 with a 128GB or 256GB option. We’re grateful about the inclusion of the MicroSD card slot, but more internal storage would be great.

The Galaxy S9 will be unveiled at Samsung’s Unpacked event on February 25 at Mobile World Congress. If you want to know what else you can expect at the trade show, check out our guide, and tune into our site for complete coverage.

This app makes the Pixel 2’s ‘Now Playing’ feature just about perfect

This simple app makes the Google Pixel 2’s ‘Now Playing’ feature so much more useful.

I love the now playing feature on the Pixel 2. The fact it’s just there telling me what tracks I can hear when I’m out and about is terrific. As lame as it sounds, there have been times I’ve been in a supermarket and wondered what that great track playing over the in-store sound system is.

But it’s not a perfect feature. However, with this app, just called Now Playing List, it becomes as close to perfect as I’d want.

The clue is in the title: It lists every track that the now playing feature on the Pixel 2 has picked up. Not only this, but you’ll see the exact date and time you heard that song and it’ll show the location you were on a map, too. All of this information is just pulled from the phone, but you can turn off the location in the app settings if you don’t want to see this.

Personally, I like that it’s there. If I’ve heard a song while I’m out somewhere, I can probably remember where I was more than the name and artist of a song if it’s something I’ve never heard before. With Now Playing List I can just go into the list and figure it out pretty easily.

If you want to highlight any favorites, you can, and from within the app you just tap a button and you can go off and listen to it from the service of your choice. In my case, I set Spotify as default so I just tap on the songs and can go right out to the Spotify app to listen.

If your list gets a little unwieldy then you can simply delete entries on it, and there’s a pretty nifty dark theme, too, that you’ll probably want to enable. Ultimately, if you like the now playing feature on your Pixel 2 but wish it could do more, then the $0.99 asking price is well worth it for what you’re getting here.

Amazon has a neat trick for keeping Alexa quiet during its Super Bowl ad

There’s more to Amazon’s Super Bowl ad than Cardi B trills.

Shortly after releasing a brief teaser, Amazon uploaded its entire 90-second Super Bowl commercial for the world to see ahead of the big game. The ad showcases a number of celebrities filling in for Alexa after she loses her voice, and during the whole thing, the hot word “Alexa” is said 10 different times.

Previous commercials from other companies have used assistant hot words in intrusive ways, but Amazon’s done something special to ensure that your Alexa doesn’t continually go off when its ad is airing.

Undetecable audio cues keep Alexa quiet during commercials.

All the way back in September of 2014, Amazon published a patent by the name of “Audible command filtering.” The patent describes two different methods for preventing Alexa from waking up when its name is said, and of the two, Amazon went with one that sends out an acoustic tone – not noticeable by humans – to cue Alexa to remain silent.

Amazon started to really push its Echo speakers with short advertisements about a year ago, and shortly after this, Reddit user Aspyhackr decided to investigate why the ads weren’t triggering their Echo even though they clearly say “Alexa” at one point or another. After running a few tests, they were able to conclude (and confirm through tests), that the commercials send out audio signals anywhere from 3,000 to 6,000Hz so that Alexa doesn’t respond with a command.

The same technique will be used during Sunday’s game, and while it’s not technically new, it’s a nice reminder that there’s more to Amazon’s commercials than meets the eyes (or voice).

When is Google going to release Android P?

Android P is coming, and probably much sooner than usual.

If there’s one thing you can always count on from Google’s annual developer conference, Google I/O, it’s a healthy dose of what’s next for Android. Google takes a large amount of its conference to help developers prepare their apps for the new features coming to Android, and show off where it can for visibly new things. We know to expect lots of information about Google’s next steps in software instead of hardware these days, because the software part is released in phases over several months as Developer Previews.

Considering Google is hyping its I/O conference a little earlier this year, and a few other bits of information we’ve scrounged up, it seems likely the initial Developer Preview for Android P will be here sooner than you think.

Chromebooks and Android P: Jerry has some thoughts!

Android P DP1

Unlike previous years where Google announced the next version of Android at I/O, last year the Developer Preview came long before the conference. By the time Google took to the stage in the middle of May 2017, developers had been playing with Android O DP1 for nearly two whole months. The final version of Android Oreo looked very different by the time it finally launched on the Pixel 2 in October, but the playground had been open for quite a while in the mean time.

With Google I/O starting on May 8 this year, it’s likely we’ll get the first Developer Preview for Android P a little earlier as well. Last year we saw Android O DP1 initial release a couple of weeks into March, which isn’t that far away at all. If Google’s schedule has been accelerated due to the earlier launch of the conference, we could be a few short weeks away from the first taste of the next version of Android.

Android P is already here for some

Like every company, Google internally tests lots of things before sending it out into the world. Part of that testing includes visiting websites like this one from those super secret versions of Android. Each year we see a slow buildup of traffic from that unreleased version of Android leading up to the initial announcement. It starts with a couple of pings over a week, and build up to several pings per day. By the time a Developer Preview is released, there’s a nice graph in our analytics of mystery Android users in a steady upward trend.

This information doesn’t guarantee much, after all anyone can tell their browser to report itself as anything if they know how, but it’s a steady ramp up every year that gives us a fairly good idea of when Google is going to be doing its thing. We know Googlers are playing with early versions of Android P, and we know they’ve been using it more and more over the last two weeks. Based on the traffic we are already seeing for Android P, it’s possible Google will announce the Android P Developer Preview earlier than last year. In fact, it’s possible we’ll hear more about Android P from Google before the end of February.

What does all of this mean?

Based on previous timelines from Google and some of the activity we’re starting to see, it looks like Android P will be made available to developers earlier than last year. If it were to start at the beginning of March instead of closer to the end like last year, it would likely move the entire cycle ahead by a month. If Android P is ready to go a month earlier than usual, it could mean something more dramatic like the next Pixel phones coming up to a month earlier as well.

The whole timeline could have been moved up by a month.

Given what we’re seeing with Samsung making the Galaxy S9 available earlier this year as well, it could also mean the next big phone from Samsung — such as the Galaxy Note 9 — launches with the next version of Android instead of waiting for an update like usual. Remember Google regularly provides its partners with access to new versions of Android much earlier than public developers, making it possible Google’s ultimate goal for 2018 is to do away with the visual stigma associated with the latest version of Android having so few people using it by the end of the year.

A lot of this is speculation, based largely on prior experience with Google’s behavior in the past. A new version of Android is always fun to play with, and when it comes to encouraging developer and hardware partner support earlier is always better. Until then, we can sit around and think some deep thoughts on what the P is going to stand for.

Deal: Android One Moto X4 available on Project Fi for $249 ($150 off)

Just makes sure you activate the phone within 30 days to get the sale price.

If you’re in the market for a solid, mid-range Android phone, it’s hard to do much better right now than the Moto X4. The X4 may ditch the customizable nature of past Moto X devices, but it still offers an incredibly well-rounded smartphone experience with a very fair retail price of $399.

We’ve got no problem recommending the X4 at that price, but if you’re on Project Fi, you can now pick it up for a mere $249. That’s the lowest price we’ve seen on the Moto X4 yet, even outdoing the Prime Exclusive variant that requires you to sell your lock screen to Amazon ads. Also, for comparison’s sake, that makes the Moto X4 the same price as its less powerful Moto G5 Plus sibling.

It’s also worth noting that this is the Android One model of the phone, so while you won’t have access to Alexa like you do with the regular unlocked version, you do get a more stock-like Android experience with faster software updates.

You will need to activate the phone on Project Fi within 30 days of shipment in order to qualify for the deal, and failing to do so will result in you being charged the full $399. However, since there’s no minimum activation time, you could technically buy the X4, activate it for $20, pause or cancel your Project Fi subscription, and the take the phone to another carrier.

If you’re interested in this deal, it’s available now until February 14 at 11:59 PM PDT.

Action Launcher v34 adds new animations and improved adaptive icon support

The v34 update has a new folder animation, better adaptive icon support, and more.

A little less than a month ago, Action Launcher v33 was released with a highlight feature called “AdaptiveZoom.” AdaptiveZoom is a new app-opening animation that gradually fills your phone’s screen with the background color of each app icon, and with v34, there’s a new zoom animation that perfectly compliments it.

The new zoom animation features the same gradual zoom of AdaptiveZoom to reveal all of the apps present in a given folder, and when used alongside AdpativeZoom for opening individual apps, the end result looks darn good.

In other AdaptiveZoom news, the v34 update also introduces a new API to give developers more control over how their apps work with this. AdaptiveZoom can look a little messy if an app already features a branded launch screen, and with the API, developers will be able to ensure a much smoother and cleaner animation for folks using AdaptiveZoom.

Action Launcher v34’s new folder animation.

Sticking with the whole adaptive theme, Action Launcher v34 introduces a couple new tools for its AdaptivePack companion app. First off, a new “AdaptivePack Fallback” can be used on phones running Android Oreo. This will tell Action Launcher to prioritize an application’s native icon if it’s adaptive, but if it’s not, a themed version will be used. Additionally, if an icon doesn’t have a first-party adaptive icon and isn’t supported by AdaptivePack, a “faux adaptive icon” will be used to ensure you’ve got adaptive icons no matter which apps you have.

Rounding all of this out, you’ll also see Oreo’s drag animation when moving apps around on your home screen, Action’s Launcher’s calendar icons are now adaptive, app boot time has been reduced, and the launcher as a whole is more stable to use.

UK doctors plan country’s first three-person fertilization procedure

UK officials have approved two women for mitochondrial replacement therapy, the fertilization procedure that results in a baby technically parented by three people, the Guardian reports. The procedure, which still isn’t approved in the US, was legalized in the UK in 2015 and the Newcastle Fertility Centre, where the two women will be treated, was granted a license to perform the procedure last March. While it’s not the first time a procedure like this has been done, it is the first time it will happen in the UK.

The two women reportedly carry genes that cause a condition called MERRF syndrome — a rare disorder affecting the muscles and nervous system that can result in recurrent seizures, movement issues and dementia. The genes that cause the syndrome are transferred to offspring through a mother’s mitochondrial DNA, and that’s where mitochondrial replacement therapy comes in. To remove the risk of MERRF, doctors use the father’s sperm to fertilize an egg from both the mother and a donor who doesn’t carry the genes. Then, the nucleus, which carries most of our genetic material, is removed from the donor egg and replaced with the nucleus from the mother’s egg. This way, the mitochondria with the tainted genes are left behind in the mother’s egg, which won’t be used. All of the genes that determine what we look like are provided by the mother and father, while healthy mitochondria, which contain only 0.2 percent of our genes, are provided by the donor. The result is an embryo with three people’s genetic material.

In 2016, a baby was born from a similar technique. It differed in that it swapped the mother and donor nuclei before the eggs were fertilized rather than after, because the parents objected to wasting an embryo due to religious regions. But it was successful. It was done in Mexico since the US, where the doctor who performed the treatment was based, doesn’t allow the procedure. A similar technique called cytoplasmic transfer also results in three-parent children and it has been performed dozens of times around the world. Instead of swapping nuclei, mitochondria from a donor is injected into a mother’s egg. It was pioneered in the 1990s by US embryologist Jacques Cohen, but the US Food and Drug Administration halted use of the procedure due to safety concerns. While it’s unclear if it was a result of the treatment, a small number of fetuses and children born through cytoplasmic transfer developed genetic and developmental disorders.

Mitochondrial diseases aren’t curable and many are very hard to treat, so treatments like mitochondrial replacement therapy stand to help a lot of people and save lives. “It is absolutely fantastic that we have got to this point in such a well-regulated and controlled way,” Sian Harding, director of the British Heart Foundation Imperial Cardiac Regenerative Medicine Centre in London, told the Guardian. “It is going to be so important now to follow up and understand whether this is successful and how we can take it forward. If you don’t follow up the children, we just won’t know whether this is the right thing to do.”
