Colonial Pipeline has cyber insurance policy – sources

Published

on

LONDON (Reuters) – Colonial Pipeline has cyber insurance arranged by broker Aon, with Lloyd’s of London insurers AXA XL and Beazley among the underwriters, three sources told Reuters on Thursday.

Colonial Pipeline has begun to restart the nation’s largest fuel pipeline network after a ransomware attack shut the line, triggering fuel shortages and panic buying in the southeastern United States.

The cyberattack halted 2.5 million barrels per day of shipments of gasoline, diesel and jet fuel last Friday after the most disruptive cyberattack ever on U.S. energy infrastructure.

Insurance Insider reported the news late on Wednesday, saying the cover was for at least $15 million.

Cyber insurance typically covers ransom payments and insurers often provide staff to negotiate with the hackers, in addition to IT and public relations services.

Colonial Pipeline does not plan to pay the ransom, sources familiar with the company’s response told Reuters on Wednesday.

Bitcoin jumps after Musk says Tesla could use it again

Published

on

SINGAPORE (Reuters) – Bitcoin hit a two-week peak just shy of $40,000 on Monday, after another weekend reacting to tweets from Tesla boss Elon Musk, who fended off criticism over his market influence and said Tesla sold bitcoin but may resume transactions using it.

Bitcoin has gyrated to Musk’s views for months since Tesla announced a $1.5 billion bitcoin purchase in February and said it would take the cryptocurrency in payment. He later said the electric car maker would not accept bitcoin due to concerns over how mining the currency requires high energy use and contributes to climate change.

“When there’s confirmation of reasonable (~50%) clean energy usage by miners with positive future trend, Tesla will resume allowing Bitcoin transactions,” Musk said on Twitter on Sunday.

Bitcoin rallied more than 9% after that message, breaking above its 20-day moving average, and it climbed a tiny bit further in Asia to hit $39,838.92.

“The market had been going through another round of correction over the weekend … until Elon Musk’s tweet of accepting BTC again for Tesla purchases changed sentiment,” said Bobby Ong, co-founder of crypto analytics website CoinGecko.

He said the market was also supported by software company and major bitcoin-backer MicroStrategy raising half a billion dollars to buy bitcoin.

Bitcoin is up about 33% this year but has collapsed from a record peak above $60,000 amid a regulatory crackdown in China and Musk’s apparently wavering enthusiasm for it. Telsa stock is down about 30% since the company’s bitcoin purchase.

Musk’s tweet was made in response to an article based on remarks from Magda Wierzycka, head of cybersecurity firm Syngia, who in a radio interview last week accused him of “price manipulation” and selling a “big part” of his exposure.

“This is inaccurate,” Musk said. “Tesla only sold ~10% of holdings to confirm BTC could be liquidated easily without moving market.”

Musk had tweeted in May that Tesla “will not be selling any bitcoin” and “has not sold any bitcoin,” but investors are keenly awaiting Tesla’s next earnings update – due next month – for any disclosure of changes to its position.

Musk has taken issue with the vast computing power required to process bitcoin transactions and in early June posted messages appearing to lament a breakup with bitcoin.

Other cryptocurrencies were steady after weekend gains, with ether at $2,491 and one-time Musk darling dogecoin buying about 32 U.S. cents on crypto exchange Binance.

Prophet google


Today Facebook is open sourcing Prophet, a forecasting tool available in Python and R. Forecasting is a data science task that is central to many activities within an organization. For instance, large organizations like Facebook must engage in capacity planning to efficiently allocate scarce resources and goal setting in order to measure performance relative to a baseline. Producing high quality forecasts is not an easy problem for either machines or for most analysts. We have observed two main themes in the practice of creating a variety of business forecasts:
· Completely automatic forecasting techniques can be brittle and they are often too inflexible to incorporate useful assumptions or heuristics.
· Analysts who can produce high quality forecasts are quite rare because forecasting is a specialized data science skill requiring substantial experience.

Width of the Language google


We consider the problem of quantifying information flow in interactive systems, modelled as finite-state transducers in the style of Goguen and Meseguer. Our main result is that if the system is deterministic then the information flow is either logarithmic or linear, and there is a polynomial-time algorithm to distinguish the two cases and compute the rate of logarithmic flow. To achieve this we first extend the theory of information leakage through channels to the case of interactive systems, and establish a number of results which greatly simplify computation. We then show that for deterministic systems the information flow corresponds to the growth rate of antichains inside a certain regular language, a property called the width of the language. In a companion work we have shown that there is a dichotomy between polynomial and exponential antichain growth, and a polynomial time algorithm to distinguish the two cases and to compute the order of polynomial growth. We observe that these two cases correspond to logarithmic and linear information flow respectively. Finally, we formulate several attractive open problems, covering the cases of probabilistic systems, systems with more than two users and nondeterministic systems where the nondeterminism is assumed to be innocent rather than demonic. …

Deep Information Network google


We describe a novel classifier with a tree structure, designed using information theory concepts. This Information Network is made of information nodes, that compress the input data, and multiplexers, that connect two or more input nodes to an output node. Each information node is trained, independently of the others, to minimize a local cost function that minimizes the mutual information between its input and output with the constraint of keeping a given mutual information between its output and the target (information bottleneck). We show that the system is able to provide good results in terms of accuracy, while it shows many advantages in terms of modularity and reduced complexity. …

Acquisition Thompson Sampling (ATS) google


This paper presents Acquisition Thompson Sampling (ATS), a novel algorithm for batch Bayesian Optimization (BO) based on the idea of sampling multiple acquisition functions from a stochastic process. We define this process through the dependency of the acquisition functions on a set of model parameters. ATS is conceptually simple, straightforward to implement and, unlike other batch BO methods, it can be employed to parallelize any sequential acquisition function. In order to improve performance for multi-modal tasks, we show that ATS can be combined with existing techniques in order to realize different explore-exploit trade-offs and take into account pending function evaluations. We present experiments on a variety of benchmark functions and on the hyper-parameter optimization of a popular gradient boosting tree algorithm. These demonstrate the competitiveness of our algorithm with two state-of-the-art batch BO methods, and its advantages to classical parallel Thompson Sampling for BO. …

Spotlight on Xbox Game Pass as Microsoft showcases upcoming games

Published

on

By Supantha Mukherjee

STOCKHOLM (Reuters) – Microsoft on Sunday showcased 30 upcoming games and said most of those titles will be available on its monthly subscription service, Xbox Game Pass.

The company said it would launch https://www.youtube.com/watch?v=1YnVzOA2wNs&ab_channel=Xbox new games on Game Pass every month through the end of the year, including titles such as PC strategy series “Age of Empires IV” and racing game “Forza Horizon 5.”

One of Microsoft’s big-ticket games, “Halo Infinite,” is now set for a holiday launch this year after being delayed due to the challenge of developers being stuck at home during coronavirus restrictions.

Several of the game launches announced by Microsoft at the E3 conference came from video game publisher Bethesda, behind hits such as Fallout and Doom. Microsoft last year bought ZeniMax Media, parent company of Bethesda, for $7.5 billion.

Microsoft also announced launch dates of two big-budget games, exclusive to Xbox and PC – role playing game “Starfield” and vampire-themed shooting game “Redfall.” “Starfield” will launch on Nov. 11, 2022 and “Redfall” next Summer. 

Both Microsoft and Sony launched their next-generation gaming devices in November last year and have seen heightened demand for the consoles as gamers stuck at home due to the pandemic snapped up the devices.

Gaming analytics firm Newzoo forecasts that the global games market will generate revenue of $175.8 billion in 2021, with 2.9 billion players, and surpass $200 billion in 2023.

Microsoft has also been developing its cloud gaming service to attract casual gamers and its own streaming devices.

Game Pass has hundreds of games playable on Xbox consoles, Android devices and PCs with a $9.99 monthly fee.

“What makes us different from a service like Netflix is that we give players both options, a subscription package and also a full retail store,” said Phil Spencer, head of Xbox.

Musk says Tesla will accept bitcoins when miners use more clean energy

Published

on

(Reuters) -Tesla Inc Chief Executive Officer Elon Musk tweeted on Sunday that the electric carmarker will resume allowing bitcoin transactions when miners who verify transactions use more renewable energy.

“When there’s confirmation of reasonable (~50%) clean energy usage by miners with positive future trend, Tesla will resume allowing Bitcoin transactions,” he said in a tweet.

Bitcoin rose 5.1% to $37,360.63 at 1810 GMT (2:10 p.m. ET) on Sunday, adding $1,817.87 to its previous close, after Musk’s tweet.

Musk also said that Tesla sold about 10% of holdings to confirm bitcoin could be liquidated easily without moving market.

He announced in May that Tesla would no longer accept bitcoin for car purchases, citing long-brewing environmental concerns for a swift reversal in the company’s position on the cryptocurrency. Bitcoin fell more than 10% after his tweet.

The billionaire said that he believed cryptocurrency has a promising future, but it cannot be at great cost to the environment.

In February, Tesla revealed it had bought $1.5 billion of bitcoin and would accept it as a form of payment for cars.
