The well-known game company EA (Electronic Arts) made a splash on GitHub, open-sourcing part of the source code of two games in the Command & Conquer series! The two games are: Tiberian Dawn and Red Alert.
The .iml file is IntelliJ IDEA's project configuration file, containing some configuration info about the current project. Sometimes after importing a project you'll find that the .iml file isn't generated automatically, causing the project structure to not display properly. In that case we need to generate the .iml file manually.
Fastjson has a remote code execution vulnerability; the restriction of the autotype switch can be bypassed, and a chained deserialization attacker can craft a deserialization exploit chain, ultimately achieving remote command execution. This vulnerability itself cannot bypass Fastjson's blacklist restriction; it needs to be combined with a deserialization exploit chain not on the blacklist to complete the full exploitation.
Earlier I wrote "Key-Exchange Logic for Encrypting Interface Data in Front-End/Back-End Separated Projects (RSA, AES)", explaining the encryption/decryption strategy when front and back ends exchange data. As my understanding and grasp of network programming grew, two months later I had to write another addendum to patch my previous article, because improper use still can't achieve absolute security. The previous article didn't mention the man-in-the-middle attack, so I'm adding it here.
Why can't you use double/float for transactions and financial currency in Java? In daily use, floating-point calculations with double/float often produce unexpected results, because binary can't precisely represent most decimal fractions. Today we'll discuss how to do decimal calculations correctly in Java.
Many students often use the kill command to kill processes in daily Linux use. Some use kill directly, some use kill -9, some use kill -3. What do they mean and what's the difference? Today we'll learn about the kill command and signals in Linux.
This "ip.renfei.net" upgrade supports not only IPv4 networks but also IPv6 networks, so the JSON you get may be an IPv4 or an IPv6 address. Developers, please update your programs to recognize it. If you only want to query an IPv4 address, use "ipv4.renfei.net", which supports IPv4 only.
ip.renfei.net pairs with DDNS dynamic DNS resolution for resolving dynamic IPs. In a dynamic-IP environment, it conveniently updates domain resolution records in time. On Linux, use curl ip.renfei.net to quickly query the public outbound IP. In a browser, use JavaScript to request ip.renfei.net to get the user's public IP address.

The SLF4J warning "Class path contains multiple SLF4J bindings" appears in the run log, for example after referencing sdk.renfei.net in SpringBoot. Actually this is a Jar package conflict; you just need to exclude the conflicting Jar package.
