RacerD detects hard-to-find race conditions in Java code

Facebook has begun offering broad access to RacerD, a tool intended to tackle the longstanding problem of race conditions in software.

RacerD had been available as a prototype, accessible in Facebook’s open source code base only through a series of backdoor options, said codeveloper Sam Blackshear, a Facebook research scientist. Now, the tool will run by default in Facebook’s open source Infer static analysis tool for bug detection. Initially, RacerD is available only for Java code. But plans call for expanding coverage to other languages, including C++.

With race conditions, overlapping processes trying to access the same data concurrently can cause conflicts in programs. These concurrency errors can be difficult to debug or even reproduce. “This has really been a hard problem” in computing for about 50 years, said Peter O’Hearn, a research scientist on the Infer team and co-author of RacerD.

How long til the true Google retail store arrives?

In the beginning, Google was a search company. Period.

At some point, it shifted into being a software and services company — and then a software and services company that, y’know, kinda-sorta dabbled in hardware here and there.

These days, there’s no denying it: In addition to its ongoing software and services efforts, Google is a hardware company through and through. Google has made that crystal clear with the launch of eight physical products and the accompanying shift toward emphasizing Google — not Android — as the primary ecosystem for its users. Sure, the hardware is designed specifically to showcase Google software and services, but the devices themselves are rapidly becoming an integral part of the equation.

A geopolitical row with China damages South Korean business further

Closing time came suddenly

IN A cosmetics emporium in central Seoul, rows of snail-slime face-masks sit untouched. Not long ago, visiting Chinese tourists would snap these up as avidly as a designer handbag in New York or anything from London featuring the Queen. Yet now their rejuvenating properties are failing to lure the country’s shoppers. Seo Sung-hae, a salesman, says business has slowed to a snail’s pace, because of a drop in the number of Chinese visitors. “We used to have 100 customers a day, but after THAAD, there are almost none,” he says.  

THAAD, or Terminal High Altitude Area Defence, is an American missile-defence system designed to guard against North Korea that was installed in South Korea starting in March. Chinese authorities protest that its radar could be used to spy on its territory. Chinese newspapers have encouraged consumers to boycott South Korean goods. The plan was to “bully” Korea into ditching…Continue reading

A property billionaire rescues Harvey Weinstein’s studio

AS DISTRESSED assets go, the Weinstein Company (TWC) is uniquely distressing. Much of its value was bound up in the brands of its eponymous founding brothers, one of whom, Harvey Weinstein, has been accused of sexual harassment and of assault by dozens of women in the film industry in America and elsewhere. Amazon Studios, Apple and some television networks have hastened to cut ties with the studio, unwind production deals and remove Mr Weinstein’s name from credits. Mr Weinstein’s accusers may well sue the company. It was already heavily indebted after a recent string of box-office flops.

Who would see an opportunity? Aside from TWC’s particular troubles, independent films are a tough business, and the studio has had to haggle with creditors. But for a vulture investor some of the studio’s assets hold value. On October 16th Thomas Barrack (pictured above), chairman of Colony Capital, a private-equity firm, said he would immediately put an undisclosed sum of cash into TWC and look…Continue reading

Why Airbus’s tie-up with Bombardier is so damaging for Boeing

Alabama bound

LIKE an airliner in service, Bombardier’s C-Series programme has had multiple highs and lows. In 2008 the Canadian firm began its attempt to break Airbus and Boeing’s duopoly on smaller jets, spooking the pair into upgrading their own models. Costs and delays pushed it near bankruptcy in 2015, followed by a bail-out from the Quebec government worth C$2.8bn ($2.2bn). The next year an order for 75 C-Series jets from Delta, the world’s third-biggest carrier, kept the programme aloft. But decisions in September and October by America’s Commerce Department to agree to demands by Boeing, an aerospace giant, to impose a total tariff of 300% on importing those planes into America risked the C-Series project crashing once and for all.

On October 16th came a surprise surge. Bombardier said it would hand over half the project to Airbus, a European aerospace firm, free of charge. Bombardier and Investissement Québec, the province’s…Continue reading

Saudi Aramco’s IPO is a mess

THE proposal to sell shares in Saudi Aramco, the world’s biggest oil company, stunned the financial markets last year. Muhammad bin Salman, now Saudi Arabia’s crown prince, promised that it would be the biggest initial public offering (IPO) of all time, valuing Aramco at $2trn. It was to be the centrepiece of his plan to transform the Saudi economy, reducing its dependence on oil. It was meant to foster financial transparency and accountability in one of the world’s most hermetic kingdoms. Above all, it would cement the young prince’s image as a bold moderniser soon to inherit the throne.

Alas, youthful impatience appears to have got the better of him. His tendency to micromanage the IPO and vacillate over where Aramco should be listed has caused delay and confusion. Matters came to a head this week when advisers, speaking anonymously, and company executives doing the same, gave conflicting reports, suggesting a mutinous atmosphere.

The kingdom’s advisers say…Continue reading
