Domestic Go language enthusiasts launch new programming language

Domestic Go language enthusiasts launched a new programming language: concave language (concave pronunciation "Wa"). At present, the code has been open sourced on Github, and a simple executable example is provided. The following are the design goals introduced by its warehouse: The initiators of this project are both Gopher, Chai Shushan and Shi Bin are also contributors to the Go community. In the development practice, for different reasons, the idea of ​​developing a new language has emerged. The style of language restraint is our greatest common divisor of the aesthetics of programming languages, so it was chosen as an initial blueprint. Needless to say: when the project started, it borrowed a lot of Go's design ideas and specific implementation - this is a compromise that had to be made under limited investment. We hope that with the development of the project, we will accumulate more original designs to provide independent innovation Tide to contribute a little strength.

5.4 million Twitter accounts leaked, selling for $30,000

On January 1, 2022, HackerOne user "zhirinovskiy" submitted a bug report stating that a vulnerability in the authentication link of Twitter's Android client could allow attackers to obtain phone numbers and/or email addresses associated with targeted accounts. Twitter confirmed the vulnerability, awarding Zhirinovskiy a $5,040 bounty. A database containing information on 5.4 million Twitter accounts was sold and made public this week on hacker forum Breached Forums for $30,000. This user confirmed that the exploit was reported by zhirinovskiy. Hackers may have collected databases of phone numbers and email addresses from data breaches on other services and matched the associated Twitter IDs.

Apple App Store exposed to a large number of pornographic apps

In the Apple App Store, there are many Apple apps with vests that look harmless to humans and animals, but when they are opened, they are colored content. In this regard, Apple's customer service responded to the current pornographic app in the App Store: I am shocked. After recording the name of the app, I will learn more about the situation. It is reported that Test Flight is the concentration of beta applications released by developers before Apple’s official review. Because the beta version of the application itself is not reviewed, many apps that engage in color choose to publish here to promote themselves.

Four tech giants call for abolition of leap seconds

Four tech giants, Google, Microsoft, Meta and Amazon, have recently called for the abolition of leap seconds. The concept of leap seconds was first proposed in 1972. When the error between the UTC Coordinated Universal Time and the Universal Time exceeds 0.9 seconds, the International Bureau of Weights and Measures will uniformly stipulate that the Coordinated Universal Time will be moved forward or backward by 1 second at the end of the year or in the middle of the year. Leap seconds have caused network platforms to malfunction many times in the past. In response to this problem, Google proposed a leap second compensation plan in 2011: adjust the network time protocol server inside the system to add a few milliseconds for each update to make up for the extra second of the leap second. But two Facebook engineers said that this solution is only suitable for solving "positive leap seconds". As the Earth's rotation pattern changes, there may also be "negative leap seconds" in the future. Failure to address this issue completely will have devastating effects on software that relies on timers or schedulers.

Musk demands October 17 trial in Twitter takeover case

Tesla CEO Elon Musk's lawyers are asking the court to hear the lawsuit against Twitter from Oct. 17 to 21, rather than Oct. 10, which Twitter has asked for. On April 26 this year, Musk and Twitter reached an acquisition agreement. Musk will acquire Twitter for $54.20 per share in cash, with a total transaction value of about $44 billion. But on July 9, Musk announced that the deal would be terminated after Twitter violated several terms of the agreement, including the issue of fake accounts. On July 13, Twitter filed a lawsuit against Musk, demanding that Musk continue to execute the acquisition agreement. Twitter hopes the court will hear the case quickly in September. On July 20, a judge ruled that the case will be heard in October this year and is expected to last five days.

iPhone 14 may support 10G network, and 5G baseband will also be upgraded

According to reports, the 5G baseband of the iPhone 14 series will also be upgraded to the Snapdragon X65 this time, supporting 10Gbps 10 Gigabit network speed. The Snapdragon X65 is the world's first 5G modem-to-antenna solution compliant with the 3GPP Release 16 5G specification, supporting major frequency bands in different regions of the world, and the world's first 10Gbps 5G baseband. However, even if the iPhone 14 series supports a 10Gbps 10G network, it is difficult to achieve such a high speed in practice, but the Snapdragon X65 has higher energy efficiency and better connection quality. I wonder if the signal of the iPhone 14 will be better. Market research agency CMR said that in the second quarter, iPhone shipments in India reached 1.2 million, a 94% increase compared to the same period last year, and the market share is expected to increase to about 4%. The main shipments are iPhone12 and iPhone12mini, iPhone13 and The two generations of iPhone 13mini contributed nearly 1 million shipments in total.

Russia decides to bypass 5G and directly develop 6G network

According to reports, Russia has decided to bypass the 5G phase and directly develop 6G networks. By 2025, the Skolkovo Institute of Science and Technology and the Institute of Radio Manufacturing Science, which is part of the Ministry of Digital Development, may receive more than 30 billion rubles (about 3.42 billion yuan) for research on the new 6G communication standard. According to reports, Russian Deputy Prime Minister Dmitry Chernyshenko instructed the Ministry of Digital Development, the Ministry of Education and Science, and the Ministry of Finance to provide additional funds for research and development in the field of 6G communications by August 1, and the Deputy Prime Minister's Office confirmed to Kommersant that the order has been issued. . As part of the project, the Skolkovo Institute of Science and Technology and the Institute of Radio Manufacturing Sciences proposed to revise the roadmap for the development of fifth-generation mobile communication networks. The document was formulated by Rostec and approved in November 2020 at a cost of 208.15 billion rubles (about 23.729 billion yuan) to implement.

Apple has hired Lamborghini R&D veteran to join car project

Apple is moving forward with work on expanding its car project team. Apple has hired Luigi Taraborelli, a 20-year veteran of Italian car company Lamborghini, reports say. During his time at Lamborghini, Tara Borelli worked mainly in the company's research and development department. Most recently, Tara Borelli was the company's director of chassis and powertrains, according to his LinkedIn profile. The report pointed out that Tara Borelli has participated in the development of Lamborghini Urus, Huracan and Aventador models.

Apple closes iOS 15.5 verification channel

After releasing the official version of iOS 15.6 last week, Apple this week stopped the verification of iOS 15.5. This means that users who updated to iOS 15.6 can no longer downgrade to iOS 15.5.

Fedora will not accept CC0 licensed code

Creative Commons CC0 is a public domain license that allows anyone to publish content worldwide without restrictions. But waiver of restrictions on content does not mean waiver of trademark or patent rights. A consensus in the Free Open Source Community (FOSS) is that a license that excludes any form of patent grant or patent forbearance cannot be considered a FOSS license. The Fedora Project has announced that CC0 authorization codes will not be allowed, and existing CC0 authorization codes may continue to be used but a decision has not been made.
