Intel To Wind Down Optane Memory Business - 3D XPoint Storage Tech Reaches Its End
Intel To Wind Down Optane Memory Business - 3D XPoint Storage Tech Reaches Its End It appears that the end may be in sight for Intel’s beleaguered Optane memory business. Tucked inside a brutal Q2’2022 earnings release for the company (more on that a bit later today) is a very curious statement in a section talking about non-GAAP adjustments: In Q2 2022, we initiated the winding down of our Intel

A story of leaking uninitialized memory from Fastly
This post will go through a QUIC (HTTP/3) implementation bug in the H2O webserver. The bug is pretty interesting as it affected Fastly in a way that it allowed stealing random requests and responses from uninitialized memory of its’ nodes, somewhat similar to CloudBleed (but unlike CloudBleed, this vulnerability required a specific actions from an attacker). Initially, I was hunting for HTTP Reque

AWS makes its own Arm CPUs the default for ElastiCache in-memory data store service
Amazon Web Services has made its home-brewed Arm-powered Graviton2 processors the default for its ElastiCache service. ElastiCache is AWS’s in-memory-data-store-as-a-service and lets users create Redis or memcached implementations in the Amazonian cloud. AWS got all excited about ElastiCache on Graviton2 back in December 2019, when it said it had benchmarked Memcached-on-Arm and found 43 percent b

【独学ポートフォリオ】野球観戦アプリ「Baseball Memory」を開発してみました（Rails × MySQL × Heroku × Docker） - Qiita
はじめに はじめまして！sekkey_777と申します。 今年で29歳の社会人5年目です。 大学時代は、化学を専攻しており、白衣着て朝から晩まで実験していました。 新卒1年目は工場で勤務していましたが、3年目になる際に社内の公募でIT系の部署に移動し、現在まで2年ほどSIer的な業務に従事しております。 現職では主に総合テストなどの品質管理、ベンダーとの調整を任されることが多いです。 2022年の10月頃から簡単な自社サービスの改修にも携わっており、Python、TypeScript、AWS、Docker、SQLなどに触れていますが、開発の経験としては浅い方です。 私としてはもっと開発に携わりたいと思っているので、転職に向けて学習をしています。 今回、転職活動に向けてRuby、Railsでポートフォリを制作したため、紹介させてください！ 今後のキャリアイメージとしては、現時点ではモダンな技
Memory safety vulnerabilities represent one of the biggest threats to Internet security. As such, we at ISRG are interested in finding ways to make the most heavily relied-upon software on the Internet memory safe. Today we’re excited to announce that we’re working with Daniel Stenberg, author of ubiquitous curl software, and WolfSSL, to make critical parts of the curl codebase memory safe. ISRG i

IDE: Measuring memory usage of Haskell values and patching GHC
Posted on August 4, 2020 by Michail Pardalos As part of my Google Summer of Code project to add instrumentation to ghcide, I needed to measure the size of Haskell values in memory. After getting blocked by a bug in a GHC primop I fell down a rabbit hole of learning about GHC’s memory layout, C– and making my first contribution to GHC. In this post I want to describe that journey and hopefully enco

Safely reviving shared memory – Mozilla Hacks - the Web developer blog
At Mozilla, we want the web to be capable of running high-performance applications so that users and content authors can choose the safety, agency, and openness of the web platform. One essential low-level building block for many high-performance applications is shared-memory multi-threading. That’s why it was so exciting to deliver shared memory to JavaScript and WebAssembly in 2016. This provide
The mseal() system call allows a process to prevent any future changes to portions of its address space (thus "sealing" them); it was patterned after the mimmutable() system call in OpenBSD. mseal() generated a lot of discussion, but it was finally merged for the upcoming 6.10 kernel release. While mseal() was initially aimed at securing the Chrome browser, the hope was that it would be useful els

The answer is in your heap: debugging a big memory increase in Ruby on Rails
I recently participated in an interesting series of debugging sessions tracking down the source of a large increase in memory when upgrading a Rails application. We ultimately tracked down the cause using John Hawthorn’s Sheap heap analyzer and successfully submitted a patch to Rails. I thought it was interesting enough to write up because maybe the general approach to debugging memory issues woul
