2020: I used Grammarly to compose well written messages, aiming to leave a good and professional impression. 2025: I leave mistakes on purpose to prove the message wasn’t generated by AI. 😂

This is a horrible UX for Claude. You can upload files but then you can't chat anymore. #Anthropic #Claude

Cisco ASA's syslog format is so inconsistent that even the same event ID can appear in three different ways. It’s like Cisco developers set out to make life as hard as possible for anyone trying to parse logs with a SIEM. Unbelievable! #Cisco #ASA #Microsoft #Sentinel

Adam uyusturucu, cinsel taciz, hirsizlik, dolandiricilik, kasten yaralama gibi 17 farkli suctan adli islem gormus ama serbest birakilmis. Fakat Imamoglu’na destek yurusune katilinca tutuklaniyor. Demek ki Imamoglu’na destek olmak, 17 farkli suctan daha agir.

The decisions being made in Turkey are proof of what can happen even in a democratic country when all powers are concentrated in the hands of a single person. Today was proof that justice in Turkey is neither free nor independent.

Do you ever see something like this on AWS? I am really curious. There is always a cache issue on #Azure Portal. I still see my deleted items after a while. Confuses me. Makes me think that maybe I didn't delete them..

2 x 100K Syslog Event Test: VirtualMetric v10 vs Leading "Competitr" 😄 As a bit of fun, we tested VirtualMetric v10 against a well-known competitor (hence "Competitr"). The results were telling! #VirtualMetric #Pipelines #Routing #MultiEvent

We made a lightweight version of VMF 2.0 called VMFL, and it's 32% smaller than VMF. It’s designed for syslog/TCP/UDP packets and supports a minimum of 50K syslog messages per physical core without packet loss!

The #CrowdStrike issue highlighted the importance of having a PXE Boot option and #WinPE images available for your infrastructure. This setup allows for quick action in critical moments. This scenario should also be included in Disaster Recovery tests to ensure preparedness.

Our new Golang KV parser can parse any key/value message. For a JSON message, it works 4x to 5x faster than a standard JSON parser and uses 4x to 5x fewer allocations. It can handle various types, including CEF, LEEF, JSON, and more. #Golang #VirtualMetric
