Check Point upgrade procedure from R80.20/R80.30 to R80.40

More than two years ago, we wrote about how every Check Point administrator will eventually face the question of upgrading to a new version. This article described the upgrade from version R77.30 to R80.10. By the way, in January 2020, R77.30 became a certified version by the FSTEC. However, a lot has changed in Check Point over the past two years. In the article […]

torxy — a transparent HTTP/HTTPS proxy that allows traffic to be redirected to selected domains through a TOR server

I present the first public version of my development — a transparent HTTP/HTTPS proxy that enables traffic redirection to selected domains via a TOR server. The project was created to enhance accessibility from a home local network to websites that may be restricted for various reasons. For example, the store homedepot.com is unavailable due to geographical restrictions. Features: Works exclusively in transparent mode, configuration is only required on the router; […]

CCZE 0.3.0 Phoenix

CCZE is a utility for highlighting logs. The original project ceased development in 2003. In 2013, I compiled the program for personal use, but it turned out to be quite slow due to a suboptimal algorithm. I fixed the most obvious performance issues, after which I successfully used it for 7 years, but was too lazy to issue a release. So, […]

Online Intensive SRE: we will break everything down to the ground, then fix it, break it a couple more times, and then build it back up again.

How about we break something? We keep building and fixing everything. It's absolutely boring. Let's break something in a way that we don't get in trouble—on the contrary, we might even be praised for this mess. Then we can rebuild everything—only this time, it will be significantly better, more resilient, and faster. And then we can break it again. […]

PostgreSQL Query Profiler: how to correlate the plan and the query

Many who are already using explain.tensor.ru—our PostgreSQL plan visualization service—may not be aware of one of its super capabilities: turning a hard-to-read piece of server log… into a beautifully formatted query with contextual hints on the corresponding nodes of the plan. In this second part of my presentation at PGConf.Russia 2020, I will explain how we achieved this. […]

Monitoring Sportmaster — what and how

We began thinking about creating a monitoring system during the formation of the product teams. It became clear that our area—operations—did not fit into these teams at all. Why is that? The fact is that all our teams are built around separate information systems, microservices, and fronts, so they do not see the overall health status of the entire system. For instance, they […]
