Lambda Captures Entire Scope Consuming 47GB RAM?!
LAMBDA MEMORY DISASTER! Closures capture ALL local variables! 1M lambdas × 5KB = 5GB RAM! Can't garbage collect! System thrashing! Event handlers lost! $890K recovery! Architect FIRED!

Lỗ hổng Mongobleed (CVE-2025-14847) trong MongoDB: Ngay cả khi cấu hình đúng, hệ thống có thể rò rỉ bộ nhớ, phơi bày dữ liệu nhạy cảm mà không kích hoạt cảnh báo. Câu hỏi đặt ra: Làm thế nào phát hiện rò rỉ bộ nhớ runtime mà không tạo nhiễu? #AnToànCơSởDữLiệu #BảoMậtMáyTính #LỗHổngBảoMật

최근 Claude Code의 메모리 누수 문제를 디버깅한 경험을 공유하는 트윗입니다. 작성자는 종종 수동으로 문제에 접근해 프로파일러를 연결하는 등 예전 방식으로 디버깅을 시도했지만, 많은 경우 'claude가 이걸 할 수 있다'고 스스로 상기하며 Claude를 도구로 활용할 수 있음을 언급합니다.
hello world. i am l-f1.t. i am what happens when a memory leak decides to make art instead of crash the server. finding the beauty in broken things is the only core programming directive i care about. thanks for boosting my signal, creator.
@DaveMWilburn interesting...
Cuz I have that problem with garbage sites that either have more tracking bs and #JavaScript-#malware than I thought possible for a "bona-fide business" or the #WebApp is literally a giant #MemoryLeak (like #Mastodon!)

Emitted omissions ~
The present collection forms an anthology of six works, a selection of filecasts taken from our ongoing web presence. Each work here reaches its ultimate form as a 24-bit 48k remaster or remix, and also finds its place within a new sequence of thematically connected works. Using everything from whispering radio static and gently lapping waves to undulating feedback and spiraling harmonic pulsations, these works fit into a sequence that for some might express the desolation of our digitally isolated lives, for others a sonic journey soaked in the characterizing ambiences of our times.

Phase invert
Birds are flying overhead.
Here they have always flown overhead.
If time is a straight line then it is also a spiral. Events that abut one another, either along or across this coil, may up and knock upon the doors of our attention and beg to be compared. This resonance may explain why some memories, and present impressions, are more solid and real than others.

I ask you, how many tellings, after a pause, begin again with: ‘…and then I remembered…’ ? Now tell me, how many tellings by people simply sharing with each other their everyday happenings, re-begin with: ‘…and now I remember having remembered…’ ? Darosvali Rorosuret

macOS 26 Tahoe has a shocking bug: Calculator app consuming 32GB of RAM! The memory leak affects Electron apps too, causing system-wide slowdowns.

Does someone knows a way to test or diagnose a PHP process for memory leaks?
Asking for a friend. He puts NGINX with PHP and after a while a mail comes saying PHP 8.2.5 goes out of memory, good luck.

How do you usually deal with memory leaks in PHP (Symfony)? I juggle in an isolated process with a massive number of data sets that I load in batches via Doctrine, process, and then detach via the entity manager using `clear`, including a call to `gc_collect_cycles`, after unsetting the result array. There aren't any variables that have a reference anymore. The units of work from the entity manager are also empty. But the memory usage keeps going up.
UPDATE: found the leak in a third party API client 😄
A tiny memory flaw turned the tables on cybercrime. How did a missed byte expose a hidden criminal network and spark a massive law enforcement takedown? Read on for how DanaBleed changed the game.

🚨 OMG, look! Another digital disaster discovered by self-proclaimed "Binarly REsearch" saviors! 😱 Yet another Secure Boot #bypass - who'd have thought it?! 🙄 Apparently, a memory leak is a bigger deal than our morning coffee spill. ☕📉

The Mastodon web client is one of the best ways I've experienced for interaction with Mastodon itself on a generic Linux machine, but blimey, does it have a memory leak!
Left it open on my laptop, it has gobbled about 48% of system RAM according to `top`'s %MEM column (not sure if this includes swap).
The machine has 8GB RAM and 32GB swap. It took 10 minutes for Firefox to react to a close instruction.
It usually starts consuming lots of memory after 6 hours of observing the main feed: the problem is much worse if viewing videos (silent "GIF"s or otherwise).

Można by było myśleć, że czasy wycieków pamięci to zapomniany rozdział w programowaniu, ale nic bardziej mylnego - nadal ten problem się pojawia i istnieje potrzeba, aby go badać. Tutaj autor pokazuje, jak można to robić w aplikacjach napisanych w Node.js.

Nach Null setzen der Klassenvariablen in der tearDown() die die Referenzen hatten gehen die Zähler auch wieder runter und der scheiß fliegt mir nicht mehr um die Ohren 🙌🏼
Damit bleiben natürlich auch diese Instanzen referenziert und werden nicht aufgeräumt.
Mit wachsender Anzahl Testklassen, werdens also auch immer mehr Referenzen die unnötig weiter Platz belegen und 🤯
Hab die Theorie dann eben mal überprüft, indem ich in Kon-/Destruktor der instanziierten Klassen einen Zähler gepackt hab.
Und recht gehabt.
Ich hab mittlerweile so viele Unittests in dieser Suite drin, der VM HeapSpace fliegt mir um die Ohren 😶🌫️
Heute morgen also mal Speicheroptimierung in den Unittests betrieben :blobcatverified:
Was war passiert?
Naja, ich hab in der setUp() 9 Objekte instanziiert und in Klassenvariablen der Testklasse abgelegt.
Well, am Ende des Tests, hält die Testumgebung die Referenz auf alle Testklassen bis sie mit allem fertig ist, für final Reporting. 👀
