A vulnerability in Firefox for Android allows control of the browser via public Wi-Fi

Posted on

A serious vulnerability has been identified in the implementation of the SSDP protocol in Firefox for Android, which is used for discovering network services in the local network. This vulnerability allows an attacker on the same local or wireless network to respond to Firefox's probing requests with a UPnP XML 'LOCATION' message containing intent commands, which can open an arbitrary URI in the browser or trigger handlers of other applications.

The Raspberry Pi 4 now supports booting from USB drives

Posted on

The default eeprom firmware with a bootloader for Raspberry Pi 4 boards has been enhanced to support booting from USB drives. Previously, Raspberry Pi 4 boards could only boot from an SD card or over the network. Experimental support for USB booting was added in May, but it was unavailable in the default firmware. The initial lack of USB boot capability and […]

Easily manage complex alerts. Or the story behind Balerter.

Posted on

Everyone loves alerts. Of course, it's much better to receive a notification when something happens (or gets fixed) than to sit and look at graphs searching for anomalies. There are quite a few tools created for this. Alertmanager from the Prometheus ecosystem and vmalert from the VictoriaMetrics product group. Zabbix notifications and alerts in Grafana. Custom bash scripts and Telegram bots that periodically trigger some […]

Don't put off until tomorrow what you can do in CRM today

Posted on

You've probably noticed: when facing a long task or a challenging path to a goal, heavy procrastination sets in. The fear of starting to write text, code, focus on your health, or pursue learning… The outcome is simple and incredibly frustrating: time passes, yet nothing changes; you haven’t done anything to ease your life. At some point, it becomes distressing to think about the wasted time […]

At the XDC2020 (X.Org Developers Conference), it was announced that ARM has joined the development process of the Panfrost project, which is working on an open driver for Mali GPUs. ARM has expressed its willingness to provide driver developers with the necessary information and documentation for a better understanding of the hardware and to focus attention on development, without wasting time deciphering puzzles during the reverse engineering of binary drivers […]

Scroll support has been removed from the Linux kernel console

Posted on

As a result of the vulnerability check, support for scrolling buffers was removed from the vgacon and fbcon drivers. With the new kernel versions, scrolling the console using Ctrl-PgUp/PgDn will no longer be possible. Linus Torvalds has promised to reintegrate the code into the kernel if a new maintainer can be found to handle the buffer overflow checks. It seems all developers have shifted to graphical interfaces, and the bare console has been largely abandoned. […]

Choosing architectural style (part 2)

Posted on

Hello, Habr. Today, I continue the series of publications that I wrote specifically for the launch of the new stream of the 'Software Architect' course. Introduction Choosing an architectural style is one of the fundamental technical decisions when building an information system. In this series of articles, I propose to explore the most popular architectural styles for building applications and answer the question of when each architectural style is most preferable. […]
