Donate your extra computer cycles to combat COVID-19. The Folding@Home project uses computers from all over the world connected through the Internet to simulate protein folding. The point is to generate the data necessary to discover treatments that can have an impact on how this virus affects humanity. The software models protein folding in a search for pharmaceutical treatments that will weaken the virus’ ability to attack the human immune system. Think of this like mining for bitcoin but instead we’re mining for a treatment to Coronavirus.
Initially developed at Standford University and released in the year 2000, this isn’t the first time Hackaday has advocated for Folding@Home. The “Team Hackaday” folding group was started by readers back in 2005 and that team number is still active, so let’s pile on and work our way up the rankings. At the time of writing, we’re ranked 267 in the world, can we get back up to number 30 like we were in 2008? To use the comparison to bitcoin once again, this is like a mining pool except what we end up with is a show of goodwill, something I think we can all use right about now.
Technology frequently looks at nature to make improvements in efficiency, and we may be nearing a new breakthrough in copying how nature stores data. Maybe some day your thumb drive will be your actual thumb. The entire works of Shakespeare could be stored in an infinite number of monkeys. DNA could become a data storage mechanism! With all the sensationalism surrounding this frontier, it seems like a dose of reality is in order.
The Potential for Greatness
The human genome, with 3 billion base pairs can store up to 750MB of data. In reality every cell has two sets of chromosomes, so nearly every human cell has 1.5GB of data shoved inside. You could pack 165 billion cells into the volume of a microSD card, which equates to 165 exobytes, and that’s if you keep all the overhead of the rest of the cell and not just the DNA. That’s without any kind of optimizing for data storage, too.
This kind of data density is far beyond our current digital storage capabilities. Storing nearly infinite data onto extremely small cells could change everything. Beyond the volume, there’s also the promise of longevity and replication, maintaining a permanent record that can’t get lost and is easily transferred (like medical records), and even an element of subterfuge or data transportation, as well as the ability to design self-replicating machines whose purpose is to disseminate information broadly.
So, where is the state of the art in DNA data storage? There’s plenty of promise, but does it actually work?
It’s rarely a wise idea to put a plastic bag over one’s head, but when the choice is between that and possibly being exposed to a dangerous virus, you do what you have to. So you might as well do it right and build a field-expedient positive pressure hood.
We’ve all been keeping tabs on the continuing coronavirus outbreak in China, but nobody is following as closely as our many friends in China. Hackaday contributor [Naomi Wu] is in from Shenzhen, posting regularly from the quarantined zone, and she found this little gem of ingenuity from a [Doctor Cui] in one of the hospitals in Wuhan. Quarantines and travel restrictions have put personal protective equipment like masks and gowns in limited supply, with the more advanced gear needed by those deal most closely with coronavirus patients difficult to come by.
There’s no build information, but from the pictures we can guess at what [Dr. Cui] came up with. The boxy bit is an AirPro Car, a HEPA filter meant to clean the cabin air in a motor vehicle. He glued on a USB battery pack to power it, used a scrap of plastic and some silicone adhesive to adapt a heat-moisture exchange filter from a mechanical ventilator to the AirPro’s outlet, and stuck the tube into a plastic bag sealed around his neck. The filter provides dry, positive pressure air to keep the bag from fogging up, and to keep [Dr. Cui] from asphyxiating. Plus he’s protected from droplet contact, which is a big plus over simple paper masks.
With the news always so dark, it’s heartening to see stories of ingenuity like this. We wish [Dr. Cui] and all our friends in China the best during this outbreak.
In whichever hemisphere you dwell, winter is the time of year when viruses come into their own. Cold weather forces people indoors, crowding them together in buildings and creating a perfect breeding ground for all sorts of viruses. Everything from the common cold to influenza spread quickly during the cold months, spreading misery and debilitation far and wide.
In addition to the usual cocktail of bugs making their annual appearance, this year a new virus appeared. Novel coronavirus 2019, or 2019-nCoV, cropped up first in the city of Wuhan in east-central China. From a family of viruses known to cause everything from the common cold to severe acute respiratory syndrome (SARS) in humans, 2019-nCoV tends toward the more virulent side of the spectrum, causing 600 deaths out of 28,000 infections reported so far, according to official numbers at the time of this writing.
(For scale: the influenzas hit tens of millions of people, resulting in around four million severe illnesses and 500,000 deaths per season, worldwide.)
With China’s unique position in the global economy, 2019-nCoV has the potential to seriously disrupt manufacturing. It may seem crass to worry about something as trivial as this when people are suffering, and of course our hearts go out to the people who are directly affected by this virus and its aftermath. But just like businesses have plans for contingencies such as this, so too should the hacking community know what impact something like 2019-nCoV will have on supply chains that we’ve come to depend on.
The news this week was dominated by the novel coronavirus outbreak centered in Wuhan, China. Despite draconian quarantines and international travel restrictions, the infection has spread far beyond China, at least in small numbers. A few cases have been reported in the United States, but the first case reported here caught our eye for the technology being used to treat it. CNN and others tell us that the traveler from Wuhan is being treated by a robot. While it sounds futuristic, the reality is a little less sci-fi than it seems. The device being used is an InTouch Vici, a telemedicine platform that in no way qualifies as a robot. The device is basically a standard telepresence platform that has to be wheeled into the patient suite so that providers can interact with the patient remotely. True, it protects whoever is using it from exposure, but someone still has to gown up and get in with the patient. We suppose it’s a step in the right direction, but we wish the popular press would stop slapping a “robot” label on things they don’t understand.
Also in health news, did you know you’re probably not as hot as you think you are? While a glance in the mirror would probably suffice to convince most of us of that fact, there’s now research that shows human body temperature isn’t what it used to be. Using medical records from the Civil War-era to the 1930s and comparing them to readings taken in the 1970s and another group between 2007 and 2017, a team at Stanford concluded that normal human body temperature in the USA has been slowly decreasing over time. They proposed several explanations as to why the old 98.6F (37C) value is more like 97.5F (36.4C) these days, the most interesting being that general overall inflammation has decreased as sanitation and food and water purity have increased, leading the body to turn down its thermostat, so to speak. Sadly, though, if the trend holds up, our body temperature will reach absolute zero in only 111,000 years.
Wine, the not-an-emulator that lets you run Windows programs on POSIX-compliant operating systems, announced stable release 5.0 this week. A year in the making, the new version’s big features are multi-monitor support with dynamic configuration changes and support for the Vulkan spec up to version 1.1.126.
Any color that you want, as long as it’s amorphous silicon. Sono Motors, the German start-up, has blown past its goal of raising 50 million euros in 50 days to crowdfund production of its Sion solar-electric car. The car is planned to have a 255 km range on a full charge, with 34 km of that coming from the solar cells that adorn almost every bit of the exterior on the vehicle. Living where the sun doesn’t shine for a third of the year, we’re not sure how well this will pay off, but it certainly seems smarter than covering roads with solar cells.
And finally, here’s a trip down memory lane for anyone who suffered through some of the cringe-worthy depictions of technology that Hollywood came up with during the 70s, 80s, and 90s. Looking back through the clips shown in “copy complete” reminds us just how many movies started getting into the tech scene. It wasn’t just the sci-fi and techno-thrillers that subjected us to closeups of scrolling random characters and a terminal that beeped every time something changed on the screen. Even straight dramas like Presumed Innocent and rom-coms like You’ve Got Mail and whatever the hell genre Ghost was got in on the act. To be fair, some depictions were pretty decent, especially given the realities of audience familiarity with tech before it became pervasive. And in any case, it was fun to just watch and remember when movies were a lot more watchable than they are today.
[Editor’s note: There’s an ongoing back-and-forth about this “spyware” right now. We haven’t personally looked into it on any phones, and decoded Wireshark caps of what the cleaner software sends home seem to be lacking — it could be innocuous. We’re leaving our original text as-run below, but you might want to take this with a grain of salt until further evidence comes out. Or keep us all up to date in the comments. But be wary of jumping to quick conclusions.]
Samsung may have the highest-end options for hardware if you want an Android smartphone, but that hasn’t stopped them from making some questionable decisions on the software they sometimes load on it. Often these phones come with “default” apps that can’t be removed through ordinary means, or can’t even be disabled, and the latest discovery related to pre-loaded software on Samsung phones seems to be of a pretty major security vulnerability.
This software in question is a “storage cleaner” in the “Device Care” section of the phone, which is supposed to handle file optimization and deletion. This particular application is made by a Chinese company called Qihoo 360 and can’t be removed from the phone without using ADB or having root. The company is known for exceptionally bad practices concerning virus scanning, and the software has been accused of sending all information about files on the phone to servers in China, which could then turn all of the data it has over to the Chinese government. This was all discovered through the use of packet capture and osint, which are discussed in the post.
These revelations came about recently on Reddit from [kchaxcer] who made the original claims. It seems to be fairly legitimate at this point as well, and another user named [GeorgePB] was able to provide a temporary solution/workaround in the comments on the original post. It’s an interesting problem that probably shouldn’t exist on any phone, let alone a flagship phone competing with various iPhones, but it does highlight some security concerns we should all have with our daily use devices when we can’t control the software on the hardware that we supposedly own. There are some alternatives though if you are interested in open-source phones.
Did you get a flu shot this year? How about last year? In a world of next-day delivery and instant downloads, making the yearly pilgrimage to the doctor or the minute clinic feels like an outdated concept. Even if you get your shots free at the office, it’s still a pain to have to get vaccinated every year.
Unfortunately, there’s really no other way to deal with the annual threat of influenza. There’s no single vaccine for the flu because there are multiple strains that are always mutating. Unlike other viruses with one-and-done vaccinations, influenza is a moving target. Developing, producing, and distributing millions of vaccines every year is a massive operation that never stops, or even slows down a little bit. It’s basically Santa Claus territory — if Santa Claus delivered us all from mass epidemics.
The numbers are staggering. For the 2018-19 season, as in last year, there were 169.1 million doses distributed in the United States, up from 155.3 million doses the year before. How do they do it? We’re gonna roll up our sleeves and take a stab at it.
