Uber is reportedly looking to sell shares between $44 to $50, aiming to raise $8 to $10 billion in the offering.

This would value the company between $80 billion to $90 billion, Bloomberg reports.

Previous reports had pegged Uber’s valuation at around $120 billion.

Still, that valuation is higher than its last valuation of $76 billion following a funding round.

It’s likely this decrease in valuation is influenced by Lyft’s performance on the public market.

Since its debut on the Nasdaq, Lyft’s stock has suffered after skyrocketing nearly 10 percent on day one.

AI that can predict future source code changes from past edits might be an invaluable tool for programmers, but it’s a challenge that’s yet to be fully conquered by researchers.

A team at Google Brain, though, describe a promising new approach in a preprint paper on Arxiv.org (“Neural Networks for Modeling Source Code Edits“) that they say provides the best overall performance and scalability of any yet tested.

“At any given time, a developer will approach a code base and make changes with one or more intents in mind,” the paper’s authors write.

“It is … an interesting research challenge, because edit patterns cannot be understood only in terms of the content of the edits (what was inserted or deleted) or the result of the edit (the state of the code after applying the edit).

An edit needs to be understood in terms of the relationship of the change to the state where it was made, and accurately modeling a sequence of edits requires learning a representation of the past edits that allows the model to generalize the pattern and predict future edits.”

Toward that end, they first developed two representations to capture intent information that would scale “gracefully” with the length of code sequences: explicit representations, which “instantiate” edits in the sequence (represented as tokens in a 2D grid), and implicit representations, which instantiate subsequent edits.

While you’re waiting for the next big update of Windows 10 to arrive in May, you might want to start cleaning out some disk space.

The upgrade may require up to twice as much storage space on your PC.

According to a Microsoft advisory, the new version of Windows 10 — version 1903 — will require 32 GB or more of space to be installed.

This is twice as much as was required for the 32-bit version of Windows 10 in its previous version 1809, which required 16 GB of space.

The new larger storage requirement applies to both 32-bit and 64-bit versions of Windows, and to the Home, Pro, and Enterprise versions.

While most modern PCs should have plenty of storage space to handle 32 GB of Windows files, this could be a problem for users on older machines, especially those using smaller solid state drives rather than the typically higher capacity (but slower) hard disk drives.

Google's UK business paid £65.3m tax into the British government's coffers in its 2018 financial year, almost 40 per cent more than in the previous 12 months.

The UK arm of the search and ads giant, which employs about 3,500 staffers in the nation, this week reported its results for the year to 30 June 2018 (PDF).

They showed an 11 per cent increase in revenues, from £1.27bn to £1.41bn – although Google doesn't book ad revenues in the UK, but is rather paid for providing services to the larger group's companies.

The results said the revenue "associated with R activity" during the 2018 fiscal year made up £426m of that £1.27bn.

As for the other services to other group companies, these are not listed or broken down.

Google, of course, houses its European HQ in tax-friendly Ireland.

Those strips and gels you use to get your teeth as pearly white as possible may come with some previously unknown risks, according to new, preliminary research out this week.

It found that the key ingredient in these products – hydrogen peroxide – could be capable of damaging dentin, the second, deeper layer of our teeth that lies beneath the enamel surface.

Though organisations such as the American Dental Association do warn whitening products can cause tooth sensitivity or gum inflammation, they’re seen as temporary side effects that go away soon after you stop using them.

Research on teeth whitening has mainly focused on how hydrogen peroxide and other whitening agents affect enamel, the protective outer coating of teeth.

But the authors behind this latest research, presented this week at the American Society for Biochemistry and Molecular Biology’s annual meeting, say that considerably less attention has been paid to how whitening products affect dentin, the bony tissue that makes up most of our teeth.

Previous work by the authors, led by Kelly Keenan, an associate professor of chemistry at Stockton University in New Jersey, had suggested that whitening agents could easily enough reach the dentin layer through our enamel.

Pouring through 10 years' worth of Southern California seismic data with the scientific equivalent of a fine-tooth comb, Caltech seismologists have identified nearly two million previously unidentified tiny earthquakes that occurred between 2008 and 2017.

The new data reveal that there are about 495 earthquakes daily across Southern California occurring at an average of roughly three minutes apart.

Previous earthquake cataloging had suggested that approximately 30 minutes would elapse between seismic events.

This 10-fold increase in the number of recorded earthquakes represents the cataloging of tiny temblors, between magnitude 1.7 and 2.0, made possible by the broad application of a labor-intensive identification technique that is typically only employed on small scales.

The problem is that they can be very difficult to spot amid all of the noise," says Zachary Ross, lead author of the study and postdoctoral scholar in geophysics, who will join the Caltech faculty in June as an assistant professor of geophysics.

Ross collaborated with Egill Hauksson, research professor of geophysics at Caltech, as well as Daniel Trugman of Los Alamos National Laboratory and Peter Shearer of Scripps Institution of Oceanography at UC San Diego.
