Prototype of clinical trials in an untrustworthy environment using blockchain

Prototype of clinical trials in an untrustworthy environment using blockchain

Upon completion, cleaned data and analysis scripts are sent to the trial sponsor through the portal and these transactions are subsequently recorded onto the blockchain. When the trial sponsor wishes to apply for approval of the drug, the sponsor would send all of their finalized data and in house statistical analysis results to the regulator through the portal and these, like all other elements, would be subsequently added to the chain. We downloaded the completed clinical trials data, including all necessary components, such as raw data, case report form (CRF) components, and protocols from the open clinical trials data repository ImmPort14 (see Data Availability).

Recycling clothing gathers steam

Recycling clothing gathers steam

But Ms. Davis, who has a master’s in sustainability from Parsons School of Design, also started the program to educate consumers about the impact their clothing choices have on the environment. She looks at the “about page” for information about where it’s made, who is making it, and where the company sources Lazarev, founder of Green Tree Textiles Recycling, displays recycled fabrics made into insulation at the Stuyvesant Town Greenmarket in New York City on June 9. It also encourages customers to recycle used swimwear by offering a 10% discount for each swimsuit sent back, for up to 30% off their pass by the pop-up shop for Fair Harbor, an apparel company that produces swimwear made out of plastic bottles, in the Brookfield Place shopping center in New York City on June 9.

Chromium and the Browser Monoculture Problem

Chromium and the Browser Monoculture Problem

This topic has flared up again recently as a result of Microsoft dropping their EdgeHTML browser engine and moving Edge to Google’s Chromium engine. Google Chrome’s underlying browser engine is developed as an open source project known as Chromium. To recap, here are the three main concerns I’ve heard raised in browser monoculture discussions:

These all change quote a bit when you recognize that we aren’t talking about a Chrome monoculture; we’re talking Chromium, the underlying browser engine.

U.S. Pentagon emits more greenhouse gases than Portugal, study finds

U.S. Pentagon emits more greenhouse gases than Portugal, study finds

The Pentagon, which oversees the U.S. military, released about 59 million metric tons of carbon dioxide and other greenhouse gases in 2017, according to the first study to compile such comprehensive data, published by Brown University. The Pentagon’s emissions were “in any one year … greater than many smaller countries’ greenhouse gas emissions,” the study said. Pentagon emissions were higher than those of Portugal, ranked 57th by the Global Carbon Atlas, said Crawford.

The rise and fall of the company behind ‘Reader Rabbit’ and other games (2018)

The rise and fall of the company behind ‘Reader Rabbit’ and other games (2018)

Both Reader Rabbit and Cluefinders were the work of The Learning Company (TLC), a dominant player in the realm of educational software during its peak in the late 1980s and ’90s. So when the school secretary mentioned a new company up in Portola Valley that was working on educational software, Grimm decided to give McCormick a call. Her games, plus Rocky’s Boots and a few others, comprised the first lineup of six products released by the business — now officially renamed “The Learning Company” — in 1982.

Why are CVS receipts so long? (2018)

Why are CVS receipts so long? (2018)

To get one of the iconically long CVS receipts, you need to use your ExtraCare card, which means you need to be an ExtraCare member. Given this alignment of the stars, it seemed the only thing to do was investigate by buying a lot of cough drops from a variety of chain drugstores, plus a grocery store, and compare receipts: Rite Aid, Duane Reade, and Stop Shop, in addition to CVS. The difference in CVS receipts is 39 inches, or 3.25 feet.

R.T. Russell’s Z80 BBC Basic Is Now Open Source

R.T. Russell’s Z80 BBC Basic Is Now Open Source

One of the people I contacted was R.T. Russell, the author of the classic Z80 BBC BASIC, and he very kindly sent me the source and agreed to allow it to be distributed under the terms of the zlib license. And it’ll run faster that way:

It had tight integration with the BBC BASIC operating system, which a decent set of graphics and file primitives, meaning you could write complex programs in it very easily; it was blisteringly fast; and most intriguingly, it was also an extremely powerful macro assembler…

The original version was written by Sophie Wilson at Acorn in 1981 for their 6502-based range of BBC Micro computers and during the early eighties every school child in the United Kingdom was exposed to it, spawning a whole generation of bedroom programmers. There’s a full history on Russell’s web site, including the 8086 and Windows versions (which remain commercial products, although Russell has a open source extended BBC Basic for various other platforms).

Making Direct Messages Reliable and Fast

Making Direct Messages Reliable and Fast

How mobile apps make network requests look fast
Often, when someone is building a mobile app that wants to “mutate” state on the server (such as tell the server to send a message), they have their view layer initiate a network request. Direct’s Mutation Manager
Given the number of different network conditions we must operate within, and the number of product surfaces we must support, building a consistent retry and optimistic state policy is a difficult task. How the Mutation Manager Works
Direct’s Mutation Manager (or short: DMM) achieves these goals (and more) by creating a centralized service that owns the network requests, serializes them to disk for retries, and safely manages the flow of their resulting optimistic state.

Gut microbes eat medication

Gut microbes eat medication

Since the introduction of L-dopa in the late 1960s, researchers have known that the body’s enzymes (tools that perform necessary chemistry) can break down L-dopa in the gut, preventing the drug from reaching the brain. Using the Human Microbiome Project as a reference, Maini Rekdal and his team hunted through bacterial DNA to identify which gut microbes had genes to encode a similar enzyme. Maini Rekdal speculated that carbidopa may not be able to penetrate the microbial cells or the slight structural variance could prevent the drug from interacting with the bacterial enzyme.
