Scientists use AI, X-rays, and 3D printing to disclose a hidden Picasso

The Blind Man’s Meal is among the many most essential artworks of Pablo Picasso’s Blue Interval, nevertheless it additionally shares a canvas with a extra mysterious portray.

Beneath the oil paint lies a portrait of a unadorned lady within the form of a coronary heart. Picasso had painted over the image, which wasn’t uncommon for the artist when cash was tight.

The portray had been hid since 1903, however a mixture of AI, stereoscopic imaging, and 3D printing has peeled again the quilt.

Discovering the portray

Students had spent years looking for the portray earlier than it was lastly present in 2010.

An unfinished model of the portrait seems within the background of Picasso’s La Vie, however the unique wasn’t found till X-rays unearthed it behind The Blind Man’s Meal.

Twitter’s down for a lot of customers, who’re reporting error messages
September 29, 2021

Twitter has gone down as we speak for a lot of customers, who’re reporting points logging into the service’s web site.

The Downdetector web site stated it’s been receiving studies of issues since 11:49AM EDT.

Customers have reported seeing error messages suggesting that they refresh the web page, however the advice appears to have had little impact.

The problems logged by Downdetector seem fairly evenly break up between the web site and log-in. The Twitter app, nevertheless, seems to be working as regular.

Tell us if you happen to’ve been affected by the outage. We’ll replace this piece when we’ve got additional information. Within the meantime, attempt to not panic: you possibly can nonetheless learn TNW.

Typically main shifts occur just about unnoticed. On Might 5, IBMannounced Undertaking CodeNet to little or no media or educational consideration.

CodeNet is a follow-up to ImageNet, a large-scale dataset of photographs and their descriptions; the pictures are free for non-commercial makes use of. ImageNet is now central to the progress of deep studying pc imaginative and prescient.

CodeNet is an try to do for Synthetic Intelligence (AI) coding what ImageNet did for pc imaginative and prescient: it’s a dataset of over 14 million code samples, protecting 50 programming languages, meant to unravel 4,000 coding issues. The dataset additionally incorporates quite a few further information, corresponding to the quantity of reminiscence required for software program to run and log outputs of operating code.

Accelerating machine studying

IBM’s personal acknowledged rationale for CodeNet is that it’s designed to swiftly replace legacy techniques programmed in outdated code, a growth long-awaited for the reason that Y2K panic over 20 years in the past, when many believed that undocumented legacy techniques may fail with disastrous penalties.

Nonetheless, as safety researchers, we consider crucial implication of CodeNet — and comparable initiatives — is the potential for decreasing limitations, and the potential of Pure Language Coding

Your common software program engineer continues to be in love with Python. Married, even.

However not these at Google, Uber, Dropbox, Soundcloud, Slack, and Medium. The programmers at high firms have lengthy fallen for the language with the lovable mascot.

That’s to not say that Python is not any good. It’s nice!

However whether or not it’s for APIs, internet providers, or information processing — whereas most builders are nonetheless utilizing Python, top-performers are adopting Golang, or Go, increasingly more. As a result of it rocks.

Go was invented by an all-star trio at Google: Robert Griesemer was one of many heads behind Google’s V8 JavaScript machine and a predominant developer for Sawzall, one other language invented by Google. Rob Pike co-developed the Unix setting and co-created the Limbo programming language. With Ken Thompson, the crew had the inventor of Unix and the creator of the B language — the predecessor of C — on board.

Google was initially written in Python — sure, Python continues to be cool — however round 2007, engineers had been looking for a greater language to carry out typical duties at Google. They had been encountering issues like these, in line with a speak

In the event you’re vaccinated towards COVID-19 and again out on the planet, chances are high you’re encountering requests in your vaccination card.

An growing variety of locations require guests to show their vaccination standing earlier than being allowed in. New York Metropolis and San Francisco mandate proof of vaccination for public indoor eating, exercising, and leisure, whereas New Orleans requires vaccination or a damaging check. Different cities, resembling Los Angeles, are contemplating comparable measures. At the very least one worldwide airline and plenty of cruises require a vaccine. Employees and college students for some college districts have to be vaccinated. And lots of sports activities venues are becoming a member of the push.

One possibility is to hold your paper vaccination card (don’t laminate it). However there are additionally a number of methods to securely preserve a digital copy helpful in your cell phone.

Are there privateness considerations? 

Although it entails your well being, the knowledge truly seen on a vaccine card isn’t as delicate as that in different well being information. Most frequently, the cardboard has a reputation, date of delivery, which vaccine that particular person obtained and when, in addition to the place they obtained the vaccination.

It’s an unlucky fact that the majority fashionable devices — and the businesses that make them — are hostile to client repairs. Not solely are devices designed in a manner that virtually forces individuals to purchase a substitute for even easy repairs, however corporations usually actively make modifications to inhibit restore by shoppers and third-party restore providers.

Valve has taken a refreshingly totally different method with its upcoming Steam Deck — earlier than the Nintendo Change-like console has even launched. The corporate launched a teardown video that reveals find out how to take the unit aside and provides you take a look at its internals, in addition to clearly spelling out all of the potential pitfalls of such an operation. It’s a breath of contemporary air for these of us who consider in the best to restore.

Some would possibly argue that Valve’s language in the course of the video — “you actually shouldn’t do that” — and the design of the unit itself is counter to the best to restore. The corporate says “although it’s your PC… and you’ve got each proper to open it up and do what you need, we at Valve actually don’t advocate that you

Apple’s plan to roll out instruments to restrict the unfold of kid sexual abuse materials has drawn reward from some privateness and safety consultants in addition to by youngster safety advocacy teams. There has additionally been an outcry about invasions of privateness.

These issues have obscured one other much more troublesome drawback that has acquired little or no consideration: Apple’s new characteristic makes use of design parts proven by analysis to backfire.

Certainly one of these new options provides a parental management choice to Messages that blocks the viewing of sexually express footage. The expectation is that parental surveillance of the kid’s habits will lower the viewing or sending of sexually express photographs, however that is extremely debatable.

We’re two psychologists and a pc scientist. We’ve performed in depth analysis on why individuals share dangerous photos on-line. Our latest analysis reveals that warnings about privateness on social media don’t scale back photo-sharing nor improve concern about privateness. Actually, these warnings, together with Apple’s new youngster security options, can improve reasonably than scale back dangerous sharing of photographs.

Apple’s youngster security options

Apple introduced on Aug. 5, 2021 that it plans to introduce new youngster security options in three areas. The

After experimenting with exoskeletons, performance-enhancing medication, and AR goggles to develop tremendous troopers, the US navy has taken a punt on a brain-modulating skullcap.

The military has issued funding for a wearable gadget that analyzes how the mind disposes of waste throughout sleep.

The system can be developed by researchers at Rice College, Houston Methodist Hospital, and Baylor School of Medication. In the end, the group needs to create a headset that may deal with sleep issues in real-time.

However first, they intention to trace and regulate the move of cerebrospinal fluid because it flushes waste out of the mind. 

Presently, that is completed with cumbersome magnetic resonance imaging tools. Paul Cherukuri, government director of Rice’s Institute of Biosciences and Bioengineering, mentioned the Pentagon needs to create a extra compact different:

Since an MRI can’t be simply transported, the Division of Protection requested if we are able to design a small, moveable cap that may measure and modulate the mind well being of warfighters throughout sleep to reinforce their efficiency. Creating this prototype would require us to begin with off-the-shelf units and be taught from them in parallel with constructing our personal sensor expertise and algorithms at Rice.
