Cmm_of_wasm: From WebAssembly to Native Code via the OCaml Back End
I recently spent three months at OCaml Labs in Cambridge, where I designed and implemented an ahead-of-time compiler from WebAssembly to native code by targeting the Cmm intermediate representation of the OCaml compiler. cmm_of_wasm is a compiler from WebAssembly to native code, via the OCaml backend. cmm_of_wasm : The main novel part of the compiler, which translates away the WebAssembly operand stack and generates Cmm code. The OCaml backend: From Cmm , performs register allocation, a few low-level optimisations, and generates native object code. Otherwise, we branch to block 2 and return i1 + i2 .

REUTERS/Emmanuel Foudrot/File Photo(Reuters) - GoPro Inc (GPRO.O) on Monday took the first steps to move most of its U.S.-bound camera production out of China by the summer of 2019 to counter the potential impact from any new tariffs. GoPro said international-bound camera production will remain in China. In the company’s earnings call in November, GoPro said it had the option to move U.S.-bound production out of China in the first half of 2019, if necessary. Last month, the company forecast fourth-quarter revenue below analysts’ estimates as it battles waning demand for its products.

A UI That Lets Readers Control How Much Information They See
A UI That Lets Readers Control How Much Information They See2018 December 6Technical WritingParametric Press enables its readers to control how much information they see via a slider that has 4 options: "TL;DR", "Essentials", "Highlights", and "Everything". Last week, in our team chat, my colleague Houssein Djirdeh posted a GIF of a UI that enables readers to control how much information they see. Essentials Mode shows just the most important information. This might be a useful feature if your audience is split between beginners and experts. With Google Analytics Event Tracking it's possible to track how much aggregate time is spent in Everything Mode or Essentials Mode.
Google will shut down Google+ four months early after second data leak
Google+ has suffered another data leak, and Google has decided to shut down the consumer version of the social network four months earlier than it originally planned. Apps could also access profile data that had been shared with a specific user, but was not shared publicly. In response, Google announced plans to shut down the consumer version of Google+, which had long struggled to attract users. This time around, Google says it discovered the leak on its own and it was live for just six days — between November 7th and November 13th. “We understand that our ability to build reliable products that protect your data drives user trust,” Thacker wrote.
Tableau Software Threatened? Rival Growing at 70% Just Raised $103M
Tableau Software is a publicly-traded player in this industry. The second wave was small tools -- the piecemeal approach followed by Tableau Software. This month, Looker raised another $103 million -- bringing its total capital raised to about $280 million. Arcadia Data is growing its staff -- but not as quickly as its revenues. It seems as though there is room for Tableau, Looker and Arcadia to grow fast in this market.
Multimodal Business Models as a Product Strategy
Product success is not just about having a good product, but also having the right business model(s). In this post, I will use consumer entertainment apps (books, podcasts, videos, and music) as a lens into the different business models and product strategies of Chinese companies. Revenue is heavily concentrated in one of these two business models, which in turn drives how the companies think about creating product. In China, books are consumed very differently. All in all, Tencent Music’s business model transforms music from a solo consumption product to a lifestyle, sharable experience.
If hackers attacked the hospital (2017)
To date, malicious cyber attacks on medical devices have not caused serious harm to patients. A recent industry survey found that more than 90 percent of health care information technology systems employ networked devices. Another difficulty is that health care devices not currently in use may be needed at a moment’s notice, such as an emergency department’s CT machine. That advanced medical devices bring with them advanced risk does not mean that we take connected devices offline or halt technological advances. But as we become ever more reliant on networked high-tech medical devices, we need to recognize that protecting them from hackers is an essential part of making them reliable and safe.
