For Men Who Hate Talking on the Phone, Games Keep Friendships Alive

For Men Who Hate Talking on the Phone, Games Keep Friendships Alive

Like over two dozen other people Kotaku spoke to—the vast majority of whom were men—Gill says online gaming has replaced phone calls, and even real-life meetups. It’s a little heartwarming, then, that the men we spoke to said they rely on online games and voice chat to achieve the interpersonal closeness that can feel contrived or heavy-handed in a prearranged phone call. “The games are sort of a substitute for driving, or chopping wood, or whatever the hell guys used to do when they weren’t comfortable just talking,”
Three researchers I spoke to say that they do think that there are specific reasons why men prefer catching up casually over games instead of segmenting out intentional phone time.

Researchers discover meat-eating plant in Ontario, Canada

Researchers discover meat-eating plant in Ontario, Canada

In what is believed to be a first for North America, biologists at the University of Guelph have discovered that meat-eating pitcher plants in Ontario’s Algonquin Park wetlands consume not just bugs but also young salamanders. But until now, no one had reported this salamander species caught by a pitcher plant in North America, including Canada’s oldest provincial park, a popular destination where the plants have been observed for hundreds of years. In summer 2017, then undergraduate student Teskey Baldwin found a salamander trapped inside a pitcher plant during a U of G field ecology course in the provincial park.

Total cholesterol and all-cause mortality – a study among 13M adults

Total cholesterol and all-cause mortality – a study among 13M adults

TC levels associated with the lowest mortality were 210–249 mg/dL in both sexes in all age groups, except for the youngest groups of men, aged 18–34 years (180–219 mg/dL), and women aged 18–34 years (160–199 mg/dL) and 35–44 years (180–219 mg/dL). Inverse associations in the lower TC range were strongest at the ages for which the mean TC levels were highest (men aged 45–54 years and women aged 55–64 years), while positive associations in the upper TC range were strongest in the youngest ages (<45 years) in both sexes. Additionally, the previously reported positive associations in younger adults8, may be explained by the stronger positive associations and lower optimal range in younger ages observed in our study, combined with the higher TC concentrations and larger proportions of morbidity and mortality from heart diseases in Western populations.

In this case commands and will produce more complex outputs, for example:

Anouther feature of the is that it can look for binaries in the local . More precisely, Faqtor system checks the following conditions consequently:

Calling method with no arguments is meaningful for some factors that have their “native” input or output globs. { , , } ( ) { } ( ); Factor produced by ‘render’ will run our HTML template: { } ( ); Factor to watch changes in files: { } ( ); ‘bs’ can produce factors for usual browser-sync tasks, like ‘reload’ for example: ( ).

Media captionPictures show cracks appear in the nuclear reactor [EDF Energy]
The first pictures have emerged of cracking in the graphite bricks which make up the core of nuclear reactors at Hunterston B Power Station in Ayrshire. Image caption

The reactor core is made up of 3,000 bricks and the cracks run the full length of 1 in 10 of them

The company accepts that the cracking is ‘life-limiting’ for the reactor but will not say what it believes to be a limit beyond which it would be unsafe to operate. Image caption

The two reactors at Hunterston B can generate enough electricity to power 1.8 million homes.

SCons: A Software Construction Tool

SCons: A Software Construction Tool

SCons is an Open Source software construction tool—that is, a next-generation build tool. SCons began life as the ScCons build tool design which won the Software Carpentry SC Build competition in August 2000. This project has been renamed SCons to reflect that it is no longer directly connected with Software Carpentry (well, that, and to make it slightly easier to type…).

California utility to cut power to 27k customers to reduce wildfire risk

California utility to cut power to 27k customers to reduce wildfire risk

LOS ANGELES (Reuters) – Utility PG&E Corp planned to proactively shut off power on Saturday to 27,000 customers in Northern California due to an increased risk of wildfires, officials said. PG&E has been in touch with people in the affected areas who rely on power for their medical equipment, Adam Pasion, a spokesman for the utility, said in a phone interview. Earlier on Saturday, the utility shut down power to around 1,600 customers just north of San Francisco, in Napa, Solano and Yolo counties, also due to the risk of wildfires after forecasters said a combination of strong winds, dry conditions and warm temperatures raised the fire danger.

The vintage 74181 ALU chip: how it works and why it’s so strange (2017)

The vintage 74181 ALU chip: how it works and why it’s so strange (2017)

It turns out that there is a rational system behind the operation set: they are simply the 16 logic functions added to A along with the carry-in.2 That is, the arithmetic functions are: A PLUS f(A,B) PLUS carry-in. Then each bit of A PLUS f(A,B) will always be 1 except in the case where A is 0 and B is 1, so the result of the sum is A OR NOT B. Even though you’re doing addition, the result is a logical function since no carry can be generated. In the 74181, the four f values are supplied directly by the four Select (S pin) values, resulting in the following table:6

The chip uses the logic block below (repeated four times) to compute P and G for each bit.

There’s a lot to learn about how blue light affects our eyes

There’s a lot to learn about how blue light affects our eyes

In a recent paper published in the journal Scientific Reports, researchers at the University of Toledo have begun to parse the process by which close or prolonged exposure to the 445 nanometer shortwave called “blue light” can trigger irreversible damage in cells. In the lab, when cells were exposed to blue light directly—in theory, mimicking what happens when we stare at our phone or computer screens—the high-intensity waves trigger a chemical reaction in retinal molecules. And so far, all of the research on how real human eyes react to blue light has failed to link screens to permanent damage of any kind.

AWS costs every programmer should know

AWS costs every programmer should know

As the prices vary within a day and I could not find a reliable data source for it. So the prices above are for one CPU or core, not one instance. Here’s the price of 1 ECU in $ per hour across all instance types I looked at:

And here’s how on-demand compares with 1 year and 3 year reservations (both convertible, upfront payments):

So you want low latency, high throughput and are planning to store everything in Redis?
