After more than four years since the formation of the previous significant branch, the release of JPype 0.7 is available, allowing full access for Python applications to Java class libraries. With JPype, you can use Java-specific libraries from Python, creating hybrid applications that combine both Java and Python code. The project code is released under the Apache 2.0 license. Unlike […]
Governments in many countries impose restrictions on citizens' access to information and services on the internet. Combating such censorship is a significant and complex task. Typically, simple solutions lack high reliability or long-term effectiveness. More complex methods for circumventing blocks have downsides in terms of usability, low performance, or prevent preserving the quality of usage […]
This is the second and final part of the article on hacking external self-encrypting drives. I remind you that recently a colleague brought me a Patriot (Aigo) SK8671 hard drive, and I decided to reverse engineer it, and now I'm sharing what came out of it. Before reading further, make sure to check out the first part of the article. 4. Let’s start by dumping the internal flash of the PSoC 5. The ISSP protocol – […]
In this article, I will explain how we approached the issue of PostgreSQL fault tolerance, why it became important for us, and what we ultimately achieved. We operate a high-load service: 2.5 million users worldwide, with over 50,000 active users each day. Our servers are hosted on Amazon in a single region in Ireland, with more than 100 different servers in operation at any time, nearly half of which are […]
Developers from the Google Cloud team have identified a vulnerability (CVE-2019-9836) in the implementation of AMD SEV (Secure Encrypted Virtualization) technology, which allows for the compromise of data protected by this technology. AMD SEV provides hardware-level transparent encryption of virtual machine memory, where only the current guest system has access to decrypted data, and other virtual machines and the hypervisor cannot access it when attempting to do so […]
One of the developers from Google raised the topic of developing a cross-platform standard C library (Libc) within the LLVM project on the LLVM mailing list. For various reasons, Google is dissatisfied with the current libc implementations (glibc, musl), and the company is on the path to developing a new implementation that is proposed to be developed as part of LLVM. Recent LLVM developments have been used as a basis for building […]
Google has released version 75 of its Chrome OS, based on the Linux kernel, with an init daemon, ebuild/portage build tools, open components, and the Chrome 75 web browser. The user environment of Chrome OS is limited to the web browser, and instead of standard applications, web apps are used; however, Chrome OS includes a full multi-window interface, desktop, and taskbar. The Chrome build […]
Data classification is an interesting topic for research in itself. I love to collect information that seems necessary, and I have always tried to create logical hierarchies of directories for my files. One night I dreamt of a beautiful and user-friendly application for tagging files, which made me realize I could no longer continue the same way. The problem with hierarchical file systems is that users often encounter the issue […]
