Still thinking of ideas of new features for my coding agent.

Current ideas:

- CI integration (left behind for 0.6)
- Plugin system (candidate languages: Rhai, Lua (LuaJIT or Luau), JavaScript (QuickJS/*-NG))
- Voice dictation (have no idea how to implement it yet)

XLoader hides in fake order emails, then runs LuaJIT and injects into system tools - all in memory. https://intel.threadlinqs.com/threat/TL-2026-5227?utm_source=bluesky #ThreatIntel #MoqHao #Formbook #Agent

ハッカーがLuaJITとWindowsプロセスインジェクションを悪用、認証情報窃取マルウェア「XLoader」を隠蔽

新たなXLoader感染チェーンが確認されました。この攻撃は、認証情報を盗むマルウェアを、埋め込み型のLuaJITインタープリター内に隠します。 さらに、共有セクションインジェクションによって、マルウェアを別のWindowsプロセスへ移します。キャンペーンはビジネス関連のメールを誘い文句に使い、Agent Tesla

bit全探索では分岐をなくせるかが、行列積ではデータの並び方が速さを分けたことを、実測とアセンブリ確認で示しています。

同じ計算量でも、次に使うデータがすぐ近くにあるかどうかで待ち時間が大きく変わり、それが速さの差になります。

Morphisec analyzed an order-themed email campaign that uses obfuscated JScript to drop LuaJIT and a Lua loader, execute XLoader in memory, then transfer it into an x86 process via shared-section mapping and thread-context redirection.

Morphisec's Shmuel Uzan observed increased XLoader activity using a range of business-themed email. The execution chain involves an archive containing a single obfuscated JScript that embeds an x86 LuaJIT interpreter, a Lua loader, and an encoded native payload. www.morphisec.com/blog/from-bu...

今日のZennトレンド

C/Rust/Julia/Go/Java/JS/PyPy/LuaJIT 実行速度ベンチマーク ― 競プロと科学計算のあいだ
C, Rust, Juliaが総合的に高速な結果となりました。
速度差は言語自体の性能よりも、コンパイラの最適化やメモリ管理、書き方といった実装上の要因に大きく依存することが分かります。
特にベクトル化や配列の並び方が速度を左右し、科学計算ではライブラリの利用が素直なループ実装より圧倒的に効率的です。

!休日の暇つぶしでやった、ゆるい比較です。計測は各 1 回だけで、厳密なベンチマークではありません。数字は「だいたいこのくらい」くらいの気持ちで見てください。 はじめに休日に暇だったので、同じアルゴリズムをいろんな言語で素直に書いて、どれくらい速さが違うのかを比べてみた。最初は「C が速くて Python が遅いんでしょ」くらいの軽い気持ちだったが、やってみると、行列積で Julia が C に勝

Morphisec Uncovers Sophisticated Email Malware Campaign Using LuaJIT and XLoader to Execute Malware In Memory + Video
Introduction: An Order-Themed Email Becomes a Malware Delivery Mechanism A seemingly ordinary email about an order can become the starting point of a sophisticated malware infection. A campaign analyzed by cybersecurity researchers at Morphisec demonstrates how attackers are combining obfuscated scripting, Lua-based execution, memory manipulation, and process injection to deliver malware while attempting to avoid traditional security detection. The campaign ultimately deploys XLoader, an information-stealing malware family, using an execution chain designed to minimize suspicious activity on disk.

fuck this i'm just going to write a python script that consumes JSON defined scenes and a LuaJIT script that generates those scenes because this? this is an absolutely idiotic and frustrating and time consuming way to do anything ever

luajit compiled to wasm, where it uses a host function to invoke WebAssembly.instantiate and store that into a table, is quite fast 👀

And the #Scrapland modding fun continues, i managed to stuff a #Lua interpreter (LuaJIT to be precise) into my modloader and wire it up to Rust's retour crate so now i can hook native game frunction from Lua and override their behaviour, without having to recompile my modloader

Got LuaJIT 2.1 and the profiler modules running and... all of that appstate code I wrote seems to be making the interpreter weep...

I don't know how bad most of this is, except for the fallback to the interpreter, or how much I should care. It uses a lot of […]

проверил. в луа 5.5.1 и luajit 2.1, как и в питоне, вторая запись false отдаёт

удобно, что всего один тип для числовых значений и он сам под капотом float в int конвертит

> проверил. в луа 5.5.1 и luajit 2.1, как и в питоне, вторая запись false отдаёт

плохо варазился. Это особенность стандарта floating point: такое будет везде с double и float во всех языках

В старых версиях Lua эта особенность используется специальным образом:

That's how you can find a problem like that, there's no need for screenshots or videos, it's as simple as just telling everybody all at once to test the devices they have with various Luanti versions & compilings.

I created a monster.

I rewrote #sdl3's whole app callback system in #lua/#LuaJIT because it wasn't available through the FFI. I tried everything I could think of.

It's at the "doesn't fail in any *obvious* way" stage, and it *feels* stable, but that just means the goblins are hiding behind the […]

Honestly, I don't know what to do because I can't salvage ... > > Let's not yell? How does this relate to your device issue? I've seen you countless times yelling similar stuff. If you don't like the mod maybe fix it or change it yourself? Get someone to do it for you? I don't see why you have to keep poking TenPlus1 over it as if he will magically fix everything, he can just block you and then the situation will be different. I am an android player as well [used to, I have a pc] but I still occasionally play on a shitty phone so maybe just pipe down your mods You need to understand, I have a knack for being very specific. If something is wrong, I point it out, that's just how I work, I play games and occasionally mess around in them (Heck, I discovered a glitch in Paperboy 64 recently, but that's off-topic), and Luanti is one of those. But because I lack a PC outright, I have no choice but to resort to Android devices, and I used F-Droid's version, but of course, it seems Luanti is beginning to lose its Android compatibility after 5.16.X. Which is rather alarming. I really want Luanti to be the perfect game, shoving Minecraft out of the way, but little nuisances like the bug with MineClonia & Farming Redo (Which may be caused by MineClonia itself) just irritate me if they remain unresolved.
