The worst morale-boosting gesture I’ve experienced

The worst morale-boosting gesture I’ve experienced

It wasn’t uncommon for angry customers to make their way to the office, sneak past security, and loudly grumble at marketing managers about their billing problems. Everything you do is great! The half dozen strangers had formed a line and started doing a little song-and-dance about how lucky we were to work for Vodafone, and how our jobs improved people’s lives every day.

Announcing Timescale Cloud

Announcing Timescale Cloud

Today we are thrilled to announce the general availability of Timescale Cloud, the first fully-managed, multi-cloud time-series database service that runs on Amazon Web Services, Microsoft Azure, and Google Cloud Platform. Timescale Cloud delivers fully-managed instances of TimescaleDB (powered by PostgreSQL) with a clean & simple experience for your time-series workloads. When you combine the power of SQL with time-series, there’s a lot you can build:

We’d like to take a moment to thank our users who joined us for the Timescale Cloud Beta & Preview these past several months and provided valuable feedback:

With Timescale Cloud we are building not just the easiest time-series experience, but we have also made the service even more cost-effective versus other managed time-series offerings.

Milankovitch Cycles

Milankovitch Cycles

In the 1920s, he hypothesized that variations in eccentricity, axial tilt, and precession of the Earth’s orbit resulted in cyclical variation in the solar radiation reaching the Earth, and that this orbital forcing strongly influenced climatic patterns on Earth. However, the Earth’s eccentricity is always so small that the variation in solar irradiation is a minor factor in seasonal climate variation, compared to axial tilt and even compared to the relative ease of heating the larger land masses of the northern hemisphere. This means that solar radiation due to (1) axial tilt inclining the southern hemisphere toward the Sun and (2) the Earth’s proximity to the Sun, both reach maximum during the summer and both reach minimum during the winter.

Netflix has Identified Several TCP Networking Vulnerabilities in Linux kernels

Netflix has Identified Several TCP Networking Vulnerabilities in Linux kernels

Additionally, versions of the Linux kernel up to, and including, 4.14 require a second patch #1: Block connections with a low MSS using one of the supplied filters. On Linux kernels prior to 4.15, an attacker may be able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. An attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection.

Plaid co-founder William Hockey is leaving

Plaid co-founder William Hockey is leaving

William Hockey, co-founder, chief technology officer and president of the fast-growing fintech business Plaid, will step down next week, TechCrunch has learned. Last month, the company launched its fintech platform in the U.K.

“As we’ve done in the U.S., Plaid will become the foundation for that growth by providing access to a financial network that allows developers to deliver the experience users expect from their financial apps,” the company wrote in a blog post. Plaid chief operating officer Eric Sager, who joined earlier this year, Perret and other executives will take over engineering and product reports, among Hockey’s other responsibilities.

Myths about Testosterone

Myths about Testosterone

T’s effect on athletic performance isn’t always positive, as the IAAF’s own data on elite women athletes well demonstrates. The IAAF says it has data showing women athletes’ performance suffers following abrupt and dramatic T suppression. Women with polycystic ovarian syndrome (PCOS), the most common reason that women have naturally high T levels, and congenital adrenal hyperplasia (CAH) were recently explicitly excluded from the 2019 regulations even when their levels exceed the threshold, though the IAAF has argued that women with PCOS and CAH derive “advantage” from high T.

Likewise, recent IAAF statements highlight sex-atypical chromosomes and gonads, which functions as a dog whistle to suggest that the targeted women athletes are not “really” women.

Transforming a Tesla Model 3 into a Pickup Truck

Transforming a Tesla Model 3 into a Pickup Truck

Simone Giertz was tired of waiting for Elon Musk to unveil his new Tesla pickup truck, so she decided to make one herself. The final results are pretty impressive

The final results are pretty impressive, and while it probably won’t look anything like the “futuristic-like cyberpunk, Blade Runner pickup truck” that Musk says he plans to release later this year, it really stands on its own as a dirt-kicking, rugged, all-electric pickup truck that still has that certain Tesla panache. Musk has been hyping the Tesla pickup truck for several years now, calling it his favorite vehicle in Tesla’s lineup yet and promising it won’t look anything like other trucks on the market.

Use Coq in Your Browser: The Js Coq Theorem Prover Online

Use Coq in Your Browser: The Js Coq Theorem Prover Online

JsCoq is an interactive, web-based environment for the Coq Theorem prover, developed at the Centre de Recherche en Informatique of MINES ParisTech (former École de Mines de Paris). We don’t provide a Coq tutorial (yet), but as a showcase, we display a proof of the infinitude of primes in Coq. The proof relies in the Mathematical Components library by the MSR/Inria team led by Georges Gonthier, so our first step will be to load it and set a few Coq options:

Canadian permafrost thaws 70 years earlier than predicted

Canadian permafrost thaws 70 years earlier than predicted

LONDON (Reuters) – Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared. With governments meeting in Bonn this week to try to ratchet up ambitions in United Nations climate negotiations, the team’s findings, published on June 10 in Geophysical Research Letters, offered a further sign of a growing climate emergency. Scientists are concerned about the stability of permafrost because of the risk that rapid thawing could release vast quantities of heat-trapping gases, unleashing a feedback loop that would in turn fuel even faster temperature rises.

Amazon expands its air cargo fleet

Amazon expands its air cargo fleet

Following news from earlier this month that FedEx was dumping Amazon from its air cargo service, Amazon this morning announced the expansion of its own air delivery network, Amazon Air. “These new aircraft create additional capacity for Amazon Air, building on the investment in our Prime Free One-Day program,” said Dave Clark, Senior Vice President of Worldwide Operations at Amazon, in an announcement. Amazon also took the time today to highlight other areas where it’s investing in supply chain initiatives, including its Delivery Service Partner program, which helps people (including Amazon employees) start their own Amazon delivery business; plus Amazon’s crowdsourced package delivery workforce Flex; and its dedicated network over 10,000 trailers to increase Amazon’s own trucking capacity.
