We just renewed support for our socket based perpetual licences for 3 years. This gives us plenty of time to find an alternative solution.
- Comment on Windows 11 scores dead last in gaming performance tests against 3 Linux gaming distros 11 months ago:
It’s how long it takes the system to render the next frame. High frame times are no good. Equates to lower average fps, and poor player experience. You also want stable frame times. This equates to smooth gameplay and less “stuttering”. Anything under 20ms is considered good. 10ms and less is great. Anything over 50ms will be perceived by the player in a negative way.

- Comment on YouTube’s Crackdown Spurs Record Uninstalls of Ad Blockers 1 year ago:
I highly doubt people are uninstalling their ad blockers. If anything they’ll just disable it on YouTube if it’s that big of an issue to them.
Firefox + uBlock still works for me on desktop. For my SmartTV and my phone I’m using other frontend applications to get around the ads.

All the time!
I’ve woken up smacking myself thinking a spider is crawling on me, and then spend the next 20 minutes trying to convince myself that there’s no spider and its safe to fall asleep again.

- Comment on Hiw do you observe your server funktions? 1 year ago:
Zabbix stores all it’s data in a PostgreSQL or MySQL database. However… there are 2 ways that Zabbix Agents work. Either in passive mode, or in active mode.
Passive Agent = “poller” process on the Zabbix server sends a request to the agent asking for values for the items it’s monitoring (based on template applied to host). Depending on the number of hosts you’re monitoring and how many poller processes are configured to start with the Zabbix server, you may run into a situation where requests are queued because the poller process is too busy. Increasing the number of poller processes will fix this, but it also adds additional load to your DB as each poller process will connect to your DB to write data, and each poller process will consume a certain amount of memory. Too many and you’ll run out of RAM, or bog down your DB.
Active Agent = “trapper” process on the Zabbix server listens for item values from being sent to it from the agents. Agents will query the Zabbix server to see what templates are applied to it’s host, and will figure out what items it’s supposed to monitor. The agent will actively query the items without the Zabbix server requesting it, and will send the item values to the server as scheduled. This puts a lot less load on the Zabbix server.
Item values are not read from the DB to activate the trigger. When a value is received that matches the trigger’s expression, then the trigger is activated. Live values are used to activate triggers and trigger actions (alerts).
