✨🤦‍♂️ "vm.overcommit_memory=2 is *always* right!" proclaims the oracle of server wisdom, touting the magic #sysctl that will solve all memory woes. Because, of course, who needs nuanced memory management when you can just hope for the best? 😜✨

Giá trị trong Go không phân bổ stack/heap theo kích thước — quyết định dựa trên **thời gian sống**. Nếu biến có thể sống sau khi hàm kết thúc, nó **thoát ra heap**. Phân tích thoát (escape analysis) là quy tắc an toàn nghiêm ngặt, không phải đoán.
Hiểu điều này giúp bạn dự đoán phân bổ, tránh cấp phát không cần thiết, đặc biệt trong closure hay goroutine.
👉 Dùng `go build -gcflags="-m"` để xem phân tích.

I wrote a minimal memory allocator in C

Since, one Java application (OpenHAB) is used on my #NetBSD server I met with huge swap usage — always near 512 Mb of swap was used. This wasn't good, since I'm using SSD — I was afraid that my old SSD will wear out and die, but for now I don't have money to buy a new SSD disk :drgn_flat_sob:

Tweaked Java initial and max heap sizes (-Xms, -Xmx) and some settings for GC, to call it more often in trade of OpenHAB responsiveness — obviously it didn't help. Then I tweaked NetBSD memory management to force system to use swap only if RAM is almost full — by this cool guide: https://imil.net/NetBSD/mirror/vm_tune.html

And it doesn't help too. Suddenly for me, but looks like these settings were applied to the kernel after reboot, not after call to sysctl.

So, for now I have a system with 800-900 Mb RAM in use and ZERO swap in use :drgn_happy:

Hai phương pháp quản lý bộ nhớ ngắn hạn cho agent AI: 🧵 Thread-based vs. Session-based 🔄

Thread-based: Giữ buffer tin nhắn trong cuộc trò chuyện, reset khi thread kết thúc. Đơn giản, nhẹ, phù hợp chatbot.

Session-based: Trạng thái chia sẻ toàn session, theo dõi thực thể ngữ cảnh. Tốt cho multi-agent setups.

Theo bạn phương pháp nào tối ưu hơn cho ứng dụng của mình? #AI #MemoryManagement #AIagent #TríTuệNhânTạo #QuảnLýBộNhớ

CSL 84-7 is mostly about how useful the Dorado microcode is (i, on stock-hardware, was well jealous). Right at the back we find: «Time spent by programmers to solve storage management related problems has decreased from an estimated 40% in Mesa to an estimated 5% in Cedar». No source, no data, basically they plucked a number out of thin air, and Bob said "sure, let's go with that". And since then the stat gets copied uncritically into numerous other papers.
