Making a temporary email service truly comfortable for oneself is no easy task. It may seem simple: you Google the query 'temporary email,' find a plethora of websites, choose a mailbox, and go about your Internet activities. However, when you need to use temporary email more often than once a year, it's better to select such a site more carefully. I'm sharing my […]
An extension for PostgreSQL called AGE (AgensGraph-Extension) has been proposed, implementing the openCypher query language for manipulating sets of interconnected hierarchical data forming a graph. Instead of columns and rows, graph-oriented databases use a structure similar to a network, defining nodes, their properties, and the relationships between them. AGE is released under the Apache 2.0 license and was contributed by Bitnine under the auspices of the Apache Foundation […]
Firefox developers have continued to advance the 'HTTPS Only' mode, in which all unencrypted requests are automatically redirected to their secure page versions (replacing 'http://' with 'https://').

Background As a fan of retro hardware, I once bought a ZX Spectrum+ from a seller in the UK. Along with the computer, I received several audio cassettes with games (in original packaging with instructions), as well as programs recorded on cassettes without any special markings. Surprisingly, the data on these 40-year-old cassettes was easily readable, and I managed to load almost all the games […]

The certificate authority Digicert plans to revoke approximately 50,000 EV (Extended Validation) TLS certificates on July 11. The certificates subject to revocation were issued through accredited certificate authorities that do not appear in audit reports.

Corrective releases of the Tor tooling (0.3.5.11, 0.4.2.8, 0.4.3.6, and 4.4.2-alpha) have been released, which is used to operate the anonymous Tor network.

This vulnerability allows a remote attacker to initiate a crash of the tor process. The issue only manifests when built with the NSS library (by default, Tor is built with OpenSSL, and […]
