Project overview QEMU is a virtual machine which allows running an operating system inside of another. While there already is a Haiku port, it currently does not support any acceleration system through native virtualization (through Intel VT-x and AMD SVM.) This makes it too slow for many uses. This project aimed to bring hardware virtualization to Haiku by porting NVMM, a hypervisor that already

Smashing the state machine: the true potential of web race conditions
In my head, the state machine for the user's role looked like this: I attempted to elevate privileges by forcibly browsing directly from the role selection page to an application without selecting a role, but this didn't work and so I concluded that it was secure. However, this state machine had a mistake. I had incorrectly assumed that the GET /role request didn't change the application state. In
Two Threads, One Core: How Simultaneous Multithreading Works Under the Hood
Simultaneous multithreading (SMT) is a feature that lets a processor handle instructions from two different threads at the same time. But have you ever wondered how this actually works? How does the processor keep track of two threads and manage its resources between them? In this article, we’re going to break it all down. Understanding the nuts and bolts of SMT will help you decide if it’s a good
KEV Catalog Reaches 1000, What Does That Mean and What Have We Learned | CISA
By: Eric Goldstein, Executive Assistant Director for Cybersecurity, Elizabeth Cardona and Tod Beardsley Every organization is confronted by a common cybersecurity challenge: there are too many vulnerabilities in technology products. This makes it difficult to prioritize limited resources – with over 25,000 new vulnerabilities released in 2022 alone, where should an organization begin? As a startin
What is 3D Gaussian Splatting? Gaussian splatting is a rasterization technique for 3D reconstruction and rendering. A recent breakthrough paper by researchers at Inria (Université Côte d’Azur) and the Max Planck Institute outlines a process to generate the data needed for 3D Gaussian Splatting from a set of images. How do I create a splat? You can create a Gaussian Splatting reconstruction right o
Intel、第13/14世代CPUがクラッシュする問題の修正パッチを公開。パフォーマンスへの影響は軽微か？ | ソフトアンテナ
ホームハードウェアIntel、第13/14世代CPUがクラッシュする問題の修正パッチを公開。パフォーマンスへの影響は軽微か？ Intelの第13/14世代CPUがクラッシュするという深刻な不具合が世間を騒がせています。 Intelによればこの問題は「不正な電圧要求」、特にチップの最低動作電圧の上昇に起因する「動作電圧の上昇」に端を発しているそうで、「電圧上昇イベントは時間とともに蓄積され」、最終的にはプロセッサにダメージを与え、システムのハングアップやクラッシュを引き起こす可能性があるとのこと。 Intelはこれらの電圧上昇要求を修正するマイクロコードアップデートを提供すると発表していましたが、計画通りマイクロコードアップデートの提供が始まったことがわかりました(Ars Technica)。 今回のマイクロコードアップデートはソフトウェアアップデートで展開できず、基本的にはBIOSアップデ

JD Vance was once 'never Trump'. Now he's his running mate “I’m a ‘never Trump’ guy.

In the same year, he wrote privately on Facebook to Josh McLaurin, his former law school roommate, now a st

Craig Stuntz - On Learning Compilers and Creating Programming Languages
Posted on October 13, 2023 When I first started learning about compilers, there was something important which I didn’t understand: Designing a programming language and writing a compiler are two almost entirely different skills. There is obviously some overlap between them, but less than you might think at first! I think it’s important to know this because they are both very challenging problems!

mRNAワクチンの反復接種はSARS-CoV-2の免疫回避を促進する | 公益財団法人 東京都医学総合研究所 | 東京都
今回の論文のポイント mRNAワクチンの反復接種により血清IgG4が上昇すると、SARS-CoV-2の免疫回避を促進し、ワクチン接種の効率が落ちる原因になる。したがって、mRNAワクチンに安易に頼りすぎている現状を反省するべきかも知れない。特に、オミクロン変異株は、免疫回避能*1が強まっているので要注意である。 頻回のワクチン接種により血清IgG4が上昇し、IgG3に結合することにより、IgG3を介した抗体依存性細胞障害(ADCC)*2が阻害され、その結果、免疫寛容*3の状態になり、SARS-CoV-2の免疫回避を促進することが一つの機序として、考えられる（図1）。 ほぼ同様のメカニズムにより、頻回のワクチン接種により、がんや「IgG4関連疾患」が促進する可能性がある。 新型コロナウイルス感染症（COVID-19）の治療においては、2019年12月に新型コロナウイルス（SARS-CoV-2
