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.
On Tuesday, Google was hit with a class-action lawsuit: it was accused of tracking users' internet usage through Chrome set to "Incognito" mode, violating the privacy of millions of users. The plaintiffs say that even when users use Incognito mode, Google still collects information about the web pages they browse.
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.
Linus Torvalds announced the release of Linux 5.7 on the kernel mailing list. In his release announcement he commented: "So last week we were fairly calm, with no screams of 'let's drag out one more rc'. Fingers crossed — hopefully we won't have another situation like in 5.6, where a wifi regression landed at the last minute."
Huawei's self-developed search engine "Petal Search" went live quietly. Just three days ago I wrote "Huawei Mobile Search's AspiegelBot Crawler Found Scraping at High Frequency — Possibly Because Google Services Can't Be Used" and guessed Huawei would build its own search engine. Now it has indeed happened: Huawei's self-developed search engine went live quietly, named: Petal Search.
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.
Huawei Mobile Search's AspiegelBot crawler was recently found by webmasters scraping site info at high frequency. This AspiegelBot crawler mainly simulates an Android phone to scrape, and its UA identifier doesn't mark which company the crawler belongs to — clearly not wanting to be discovered. Later webmasters dug deeper and found the crawler belongs to AspiegelBot, an Irish subsidiary under Huawei Search; many small sites were directly scraped to a standstill.
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.
According to the latest results published on the evening of May 20 on TPC-C, the authoritative database ranking, Alipay's self-developed distributed relational database OceanBase scored above the 100-million mark for the first time in the latest TPC-C benchmark, reaching 707 million tpmC — meaning 707 million new orders created per minute, an nearly 11x improvement over the 60.88 million tpmC of October last year.
