Hello, Habr! Today we will build a system that processes streams of messages from Apache Kafka using Spark Streaming and writes the processing results to the AWS RDS cloud database. Let's assume a credit organization presents us with the task of processing incoming transactions 'on the fly' across all its branches. This can be done for the purpose of instant currency calculations […]

A vulnerability has been discovered in the SQLite database (CVE-2019-5018) that allows arbitrary code execution in the system when an attacker can execute a SQL query prepared by them. The issue stems from an error in the implementation of window functions and is present starting from the SQLite 3.26 branch. The vulnerability was fixed in the April release of SQLite 3.28 without explicit mention of security fixes. A specially crafted SQL query SELECT can lead to […]
Enthusiast Alfonso Torres, known by the nickname We1etu1n, posted a photo on Reddit showing a Nintendo Switch running Windows XP. The operating system, now 18 years old, took 6 hours to install, but Pinball 3D was able to run at full speed. It is reported that an L4T Ubuntu operating system and a QEMU virtual machine, enabling emulation of various architectures, were used for this […]
Start on this site via the link. The most convenient option for capturing information about the starter activation turned out to be the one using the optocoupler PC817. The schematic plates contain three identical circuits, all housed in ABS plastic boxes measuring 100x100 mm. Photos of the optocouplers. When connected to semiconductor relay starters, their leakage current is sufficient to trigger the PC817 […]

In psychotherapy, there is also treatment through catharsis techniques, which involve processing past negative experiences. This includes the 'poisoned pen therapy,' where the patient writes letters to express their grievances […]

Containers represent a lightweight version of the user space of the Linux operating system — in fact, they are a 'bare' minimum. Nonetheless, it is still a full-fledged operating system, and therefore the quality of this container is just as important as that of a complete operating system. This is why we have long offered Red Hat Enterprise Linux (RHEL) images, so users can have certified, modern […]
