The main branch of nginx 1.19.3 has been released, within which the development of new features continues (in the parallel supported stable branch 1.18, only changes related to the elimination of serious errors and vulnerabilities are made). Main changes: The ngx_stream_set_module module is included, which allows you to assign a value to the variable server { listen 12345; set $true 1; } Added proxy_cookie_flags directive to specify flags for […]
The Pale Moon 28.14 web browser was released, branching from the Firefox code base to provide higher performance, preserve the classic interface, minimize memory consumption and provide additional customization options. Pale Moon builds are created for Windows and Linux (x86 and x86_64). The project code is distributed under the MPLv2 (Mozilla Public License). The project adheres to the classic interface organization, without […]
Despite the addition of just a number to the version number, there are many changes in the popular text editor. Some are invisible - these are fixes for old and new Clangs, as well as the removal of a number of dependencies to the category of disabled by default (aspell, qml, libpoppler, djvuapi) when building with meson and cmake. Also, during the developer’s unsuccessful tinkering with the Voynich manuscript, TEA […]
1. Introduction The agenda was to develop a communication protocol for the nrf52832 microcontroller with two half-bridge Chinese strain gauges. The task turned out to be not easy, as I faced the lack of any intelligible information. It is more likely that the "root of evil" is in the Nordic Semiconductor SDK itself - this is constant version updates, some redundancy and intricacies of functionality. I had to write everything […]
There are a lot of services that provide information about the weather, but which one to trust? When I began to ride a bike often, I wanted to have the most accurate information about the weather conditions in the place where I ride. My first thought was to assemble a small DIY weather station with sensors and receive data from it. But I didn't "invent […]
Introduction Hello. I'm ningenMe, a web developer. As the title says, my story is about physically deleting 300 million records in MySQL. I became interested in this, so I decided to make a memo (instruction). Start - Alert The batch server I use and maintain has a regular process that once a day collects data for the last […]
According to new data obtained from DigiTimes, Apple will release a 12,9-inch iPad Pro with a Mini-LED display in early 2021. But a MacBook with such a matrix will have to wait until the second half of next year. According to the source, Epistar will supply LEDs for the iPad Pro Mini-LED displays in the near future. It is reported that each tablet will use more than 10 […]
AOC announced three E2 series monitors at once: the 31,5-inch models Q32E2N and U32E2N debuted, as well as the Q34E2A version with a diagonal of 34 inches. The new products are positioned as devices for business and professional use, as well as for ordinary users with high demands on image quality. The Q32E2N panel received a VA matrix with a QHD resolution (2560 × 1440 pixels), a brightness of 250 cd/m2 […]
According to fresh data, Apple is exploring hydrogen fuel cells for mobile devices as an alternative to conventional batteries. Such elements are designed to significantly increase the battery life of devices. In addition, they are much more environmentally friendly compared to conventional batteries. Information about new developments is revealed by a recently published patent of a Californian company. The filing is unusual in that it refers to Apple […]
The developers of the Xen project announced the implementation of the possibility of using Xen Hypervisor on Raspberry Pi 4 boards. Adaptation of Xen to work on previous versions of Raspberry Pi boards was hampered by the use of a non-standard interrupt controller that does not have virtualization support. The Raspberry Pi 4 used the regular GIC-400 interrupt controller supported by Xen, and the developers expected that there would be no problems running Xen […]
Authoritative DNS server updates PowerDNS Authoritative Server 4.3.1, 4.2.3 and 4.1.14 are available, which fix four vulnerabilities, two of which could potentially lead to remote code execution by an attacker. Vulnerabilities CVE-2020-24696, CVE-2020-24697 and CVE-2020-24698 affect code that implements the GSS-TSIG key exchange mechanism. The vulnerabilities only appear when building PowerDNS with GSS-TSIG support (“—enable-experimental-gss-tsig”, not used by default) […]
