8. The official website of Perl.com was hijacked to point to the parking site and used to distribute malware
Although the popularity has gradually declined in recent years, many systems still rely on the Perl programming language. Last weekend, the Perl infrastructure blog Perl NOC reported that the official website of Perl.com was hijacked and no longer pointed to where it should have been. It no longer points to Perl-related news sites, but instead points to a parking site. More seriously, it is used to distribute malware.
It should be noted that perl.org, the official website of the Perl programming language, is still safe and complete. Unfortunately, Perl.com is also used as a mirror or backup for modules distributed through CPAN. In other words, the hijacker may use this connection to compromise systems that use Perl and CPAN. At present, the authorities are already working on the recovery of the domain name, but there is no estimate when it will return to normal. At the same time, we strongly recommend not to visit Perl.com and remove it from CPAN settings.
9. Win10 21H2 preview releases new language packs: hinting that the old version of Microsoft Edge will be removed
It was reported on February 2 that Windows 10 version 20H2 or later will force the installation of the new Microsoft Edge browser, whether the user wants it or not. However, the traditional or old Microsoft Edge is still included in the operating system, which means that Windows 10 comes with three different browsers pre-installed: Internet Explorer, the old Edge and the new Edge.
In the new language pack released for the preview version of Windows 10 21H2, Microsoft seems to have dropped support for the old Edge browser. The move appears to be part of Microsoft's plan to remove the old version of Microsoft Edge when it releases the Fall 2021 update later this year.
Please note that the old version of Edge is still included in the preview, but the revelation indicates that Microsoft is trying to unify the web browsing experience on Windows. At some point, users will not be able to access the old version of Microsoft Edge.

1. Security: A serious bug has been found in the GnuPG encryption library
The main developer of GnuPG (GNU Privacy Guard) warns users who use the 1.9 version of the encryption library Libgcrypt to update immediately. Libgcrypt version 1.9 was released on January 19th. Google Project Zero researcher Tavis Ormandy discovered a heap buffer overflow vulnerability in this version, which overflows when decrypting part of the data. The problem is related to the wrong assumption in the block buffer management code. Exploiting this vulnerability is very simple. Users using version 1.9 need to update the encryption library immediately.
2. Microsoft calls Excel a programming language, and now it has Turing completeness
Microsoft claims that its spreadsheet program Excel is a programming language. With the introduction of LAMBDA, Excel now has Turing completeness.
If a programming language can implement any possible algorithm, then it has Turing completeness. The Calc Intelligence project of the Microsoft Cambridge Research Institute worked with the Excel team to transform spreadsheet formulas into a comprehensive programming language. Excel has two major shortcomings that prevent it from becoming a true programming language: one is that the formula language only supports scalar values such as numbers, strings, and Boolean values, and the other is that it does not support the definition of new functions.
In December last year, Microsoft announced LAMBDA, allowing users to use Excel's formula language to define new functions-it is called LAMBDA-defined functions. With LAMBDA, Excel has Turing completeness, and in theory, you can use Excel's formula language to write any calculations. LAMBDA is currently available to Beta users.
3. Microsoft announced the open source scalable storage engine, which has been in service for more than 25 years
Microsoft recently announced the open source Extensible Storage Engine (ESE). ESE is a non-SQL database engine with a service life of more than 25 years. It started with Windows NT 3.51 and is still one of Microsoft's core assets. Today, ESE is also widely used in Office 365 mail storage back-end servers, large-scale SMP systems, and every Windows client.

Cookies have been loved by most advertisers for a long time. The main reason is that cookies are regarded as third-party data and are therefore one of the main ways for advertisers to locate users on the Internet.
In recent years, Cookie has been opposed by more and more people in the industry. With the help of cookies, user data collected from users through browsers or websites are often sold and sold on a large scale by third parties, which poses a certain threat to the privacy and security of every user. Because of this, the industry has begun to generally believe that Cookie technology is becoming increasingly insecure.
However, in the past few years, the entire digital advertising ecosystem was mainly built around cookies (with a global value of nearly 330 billion U.S. dollars), so if you want to quickly find alternatives to cookies, this road is also facing huge challenges.
Recently, Google is testing an API called FLoC (Federal Queue Learning), which can effectively replace third-party cookies and be embedded in Google Chrome as a browser extension. Google said that the technology is expected to replace cookie-based advertising targeting. 【Read the original text】

Accurate recommendation system model is the core competitiveness of many Internet products. Personalized recommendation system aims to provide a "customized" product experience based on user behavior data. Kuaishou, a national-level short video app, recommends tens of billions of videos to hundreds of millions of users every day. One of the challenges it encounters is how to accurately describe and capture user interests in the recommendation system model.
The solutions used in the industry today usually combine a large number of data sets and fitting parameters to train a deep learning model, so that the model is closer to the reality. Google recently released the first trillion-level model Switch Transformer with a parameter volume of 1.6 trillion, which is four times faster than the largest language model (T5-XXL) developed by Google before. However, the total parameter volume of the fast-handed trillion-parameter fine-arrangement model exceeds 1.9 trillion, which is larger in scale and has been put into practice. Let's pass the development history of the fast-hand and fine-layout model, let us reveal its internal technical code together! 【Read the original text】
