The issue of handling out-of-memory scenarios in Linux has been raised in the kernel developers' mailing list: It is a known problem that has plagued many users for years and can be reproduced in under a few minutes on the latest Linux kernel version 5.2.6. All kernel parameters are set to their default values. Steps: Boot with the parameter "mem=4G". Then, turn off […]
A new stable release of the interface for simplifying network parameter configuration — NetworkManager 1.20 has been published. Plugins for VPN support, including OpenConnect, PPTP, OpenVPN, and OpenSWAN, are being developed within their own cycles. Key innovations in NetworkManager 1.20: Support for wireless mesh networks has been added, where each node is connected through neighboring nodes; deprecated components have been cleaned up, including the removal of the libnm-glib library, […]
Following the highly anticipated beta release of Haiku R1 at the end of last year, the developers of the open-source operating system have finally moved on to optimizing its performance. The focus is primarily on accelerating overall system performance. Now that issues of general instability and kernel crashes have been resolved, the authors have begun working on improving the speed of various internal components. In particular, […]
Today, Swiss startup DeepCode, which utilizes artificial intelligence and machine learning to automate code analysis, announced that it has secured $4 million in funding from venture funds Earlybird, 3VC, and Btov Partners. The company plans to use these funds to implement support for new programming languages in its service, as well as for marketing the product on the global IT market. Code analysis […]
The need to provide remote access to corporate environments is becoming increasingly common, whether it’s for internal users or partners who require access to certain servers in your organization. To meet these needs, most companies use VPN technology, which has proven to be a securely protected method for granting access to an organization's local resources. My company did not become […]
Today, I want to share how to set up a two-factor authentication server to protect corporate networks, websites, services, and SSH. The server will run a combination of LinOTP and FreeRadius. Why do we need this? It is a completely free and convenient solution that operates within your own network, independent of third-party providers. This service is quite user-friendly and visually clear, unlike other open-source products, and it also supports […]
The National Security Committee of the Republic of Kazakhstan has completed testing of the national 'security certificate,' as reported by the press service of the NSC RK. All citizens who installed the 'security certificate' can delete it—there is no longer a need for its use. However, the necessity to reinstall it may arise 'in cases of strengthening the digital border of the state under a special regulation.' Three weeks ago, residents of the capital of the Republic of Kazakhstan began […]
Three vulnerabilities have been discovered in the Qualcomm wireless chip stack, collectively known as "QualPwn." The first issue (CVE-2019-10539) allows remote attacks on devices using the Android platform via Wi-Fi. The second issue exists in the proprietary firmware with the Qualcomm wireless stack and enables access to the baseband modem (CVE-2019-10540). The third issue is found in the icnss driver (CVE-2019-10538) and allows for […]
In 2015, ARM introduced the energy-efficient 64/32-bit Cortex-A35 core for heterogeneous big.LITTLE architecture, and in 2016, it released the 32-bit Cortex-A32 core for wearable electronics. Now, subtly and without much fanfare, the company has unveiled the 64-bit Cortex-A34 core. This product is offered under the Flexible Access program, which gives developers access to a wide range of intellectual property, with payment options only for […]
The reduction of water supplies in California, suffering from ongoing droughts, forces farmers to seek alternative sources of income. In the San Joaquin Valley alone, farmers may need to take more than half a million acres (202,300 hectares) out of agricultural production to comply with the Sustainable Groundwater Management Act of 2014, which ultimately imposes restrictions on […]
A pair of devices from the Russian developer "Kroks" has arrived for an independent test review. These are quite compact radio frequency measurement devices, specifically: a spectrum analyzer with a built-in signal generator, and a vector network analyzer (reflectometer). Both devices have a frequency range of up to 6.2 GHz. There is interest in understanding whether these are just pocket-sized "meters" (toys), or truly noteworthy instruments, as the manufacturer positions them: […]
