x86-64 Playground is a web app for experimenting and learning x86-64 assembly.
The Playground web app provides an online code editor where you can write, compile, and share assembly code for a wide range of popular assemblers such as GNU As, Fasm and Nasm.
Unlike traditional onlide editors, this playground allows you to follow the execution of your program step by step, inspecting memory and registers of the running process from a GDB-like interface.
You can bring your own programs! Drag and drop into the app any x86-64-Linux static executable to run and debug it in the same sandboxed environment, without having to install anything.
Adobe Reader XI (11.0.23) is the final cumulative update of the Adobe Reader XI series, released in November 2017. Version 11.0.23 was designed as a security and stability patch, addressing over two dozen critical vulnerabilities found in earlier versions of Reader XI.
Key features of Reader XI (retrospective):
This version was built for Windows 7, Windows 8, Windows 8.1, and Windows 10 (initial builds, 1507-1607). download adobe reader xi 11.0.23 offline installer
Many large companies still keep a local network share of old installers for legacy systems. If you’re an employee, ask your IT department. Never download from a third-party "download manager" site (like CNET, Softonic, or Uptodown) – they bundle adware.
Adobe officially published these hashes for the English installer: Adobe Reader XI (11
Adobe’s code-signing certificate for Reader XI updates expired in 2020. Windows SmartScreen will flag the installer as "untrusted," and some antivirus software may quarantine it as a heuristic threat.
Crucial warning: Adobe no longer hosts Reader XI on its official website. Any site claiming to be "official Adobe" for this version is fake or dangerous. This version was built for Windows 7, Windows 8, Windows 8
However, if you have a legal reason (e.g., running on an isolated test lab or legacy contract), here are the least-risky sources:
"If a software version has been unsupported for more than 3 years, using it for daily PDF reading is not frugality—it's a disaster waiting to happen."
Even the "Protected Mode" sandbox in Reader XI has known escape exploits that were patched in later versions but remain open in 11.0.23.
Have you ever seen a responsive debugger? The app places the mobile experience at the center of its design, and can be embedded in any web page to add interactivity to technical tutorials or documentations.
Follow the guide to embed in your website both the asm editor and debugger.
The app is open-source, and available on Github. It's powered by the Blink Emulator, which emulates an x86-64-Linux environment entirely client side in your browser. This means that all the code you write, or the excutables you debug are never sent to the server.
everything runs in your browser, and once the Web App loads it will work without an internet connection.
