The programming iceberg...

I always look for new resources to learn programming. However, every programming language created there will be a huge documentation that is born with it.
And they are very deep shit.

When you get an error from a compiler, there are these many cryptic messages pooping your entire screen and sometimes it just makes me wonder what they are..

Does anyone even read these for fun?


g++ compiler documentation

c++ documentation

Python "print()" documentation

A year of read-only cppreference

Over a year ago (on 30 March 2025), cppreference became read-only for maintenance reasons. Since then, the only progress update was in August. There have been several discussions here in the last few months about what is happening with cppreference and when it might become editable again, but from what I understand, we simply do not know.

At this point, I fear that the lack of updates for what is basically the authoritative source on the language (other than the standard of course), linked to by IDEs and even this subreddit's sidebar, might be detrimental to the adoption of C++26 and further standards, should the situation persist. I would therefore like to ask the community whether there are other, more up-to-date resources, and whether there is any effort to, for example, fork cppreference.

I understand that software updates are complicated and I have no intention to criticise the maintainers of cppreference (who are doing it voluntarily and I am not entitled in any way to their continued work on the website), but I do not think the C++ community can afford to be bottlenecked in such a way for much longer.

MS Visual Studio 18.5 has now been Released, with one caveat...

...It still doesn't have MSVC Build Tools v14.51, only an old preview.

https://learn.microsoft.com/en-us/visualstudio/releases/2026/release-notes

At the same time, Microsoft releases Visual Studio Insiders (basically VS preview), with the MSVC Build Tools v14.51 release, not a preview.

https://learn.microsoft.com/en-us/visualstudio/releases/2026/release-notes-insiders

So, now we have - official VS Release with the MSVC Build Tools v14.51 preview.

And VS preview with the MSVC Build Tools v14.51 release.

Person (or persons?...) in Microsoft responsible for this weirdness should get annual bonus reward.

I'm building an open-source OS that can run Windows, Linux, and macOS apps together (looking for contributors)

Hey everyone,

I’ve been working on an idea that I think a lot of us have been frustrated by at some point:

Why is software still locked into operating system silos?

Windows apps only run on Windows
Linux tools require Linux environments
macOS software is completely isolated

So I started building a project (working title: FusionOS) that aims to change that.

# The idea

A universal execution layer + OS where:

Windows, Linux, and macOS applications can run side-by-side
Environments are abstracted away from the user
Compatibility is handled at the system level

On top of that, I’m exploring a multi-agent architecture where:

Agents manage dependencies and environments
Tasks can be automated and optimized dynamically

# Current direction

Right now I’m in the early stage, exploring:

Binary translation / compatibility layers
Virtualization + container hybrids
Cross-platform system abstractions
Agent-based orchestration

# Why I’m posting here

This is obviously a hard systems problem, and I don’t want to build it alone.

I’m looking for people interested in:

OS dev / kernels
low-level systems (C/C++/Rust)
virtualization / compilers
or even just thinking about better abstractions

Even if you just want to discuss the idea or poke holes in it, that’s super valuable.

Demystifying MSVC versioning for 14.50 & later

Hi folks, one of the MSVC dev leads here.

MSVC versioning is confusing, and with the change to decouple MSVC releases from Visual Studio releases (https://aka.ms/msvc/lifecycle) it's confusing-er. This post aims to clarify what's going on with 14.50 & later.

I am intentionally skipping discussion of the VS2022 & older releases that are still being supported since the servicing model is different. Know that our team still supports Visual Studio 2019 16.11 per https://learn.microsoft.com/en-us/visualstudio/releases/2019/servicing-vs2019, and Visual Studio 2022 17.12 & 17.14 as per https://learn.microsoft.com/en-us/visualstudio/releases/2022/servicing-vs2022 .

# The actual versions

Since MSVC releases are decoupled from Visual Studio releases, it's helpful to think from the standpoint of the MSVC toolchain. At any point in time, we ship:

The bleeding edge preview toolset
The current default toolset
All previous in-support toolsets

As of today, we ship the following MSVC toolsets:

14.52 the preview toolset, built from our development branch last Tuesday (April 7th)
`14.51` the default toolset, currently a 'release candidate'
14.50 the toolset we released in Nov 2025, with 3 years of support.

Our plan, as per https://aka.ms/msvc/lifecycle, is to ship a new 14.5* twice a year. So in 6 months we expect to ship 14.53 as the new 'latest preview', make 14.52 the 'current default toolset', and 14.51 will be a toolchain in support as per the support policy, along with 14.50.

# What's this about Visual Studio Insiders vs. Stable?

Visual Studio 'stable' ships monthly (https://learn.microsoft.com/en-us/visualstudio/releases/2026/release-rhythm), so if you're on the Visual Studio stable channel you'll get monthly updates to all the 14.5* toolsets. To be explicit:

The latest preview will be updated with whatever the dev team has landed in the last month
The default & other in-support toolsets will be updated with the latest fixes we have applied to them.

If you want to get MSVC toolset updates far quicker than monthly, switch to the Visual Studio Insiders channel https://visualstudio.microsoft.com/insiders/. Keep an eye on https://learn.microsoft.com/en-us/visualstudio/releases/2026/release-notes-insiders for how often these updates occur.

# Wait, you said something about a 'release candidate'?

We blogged recently https://devblogs.microsoft.com/cppblog/msvc-build-tools-version-14-51-release-candidate-now-available/ that the default toolset is moving from 14.50 to 14.51. As per https://aka.ms/msvc/lifecycle we aim to ship a new default toolset every 6 months. However, about a month before this lands in the Visual Studio 'Stable' channel we want to land the new default toolset in the 'Insiders' channel. This gives folks using Insiders about a month to give us feedback to fix 14.51 bugs before it shows up for 'Stable' channel users.

# How do I get these tools? Why did 14.50 disappear yesterday? Where is 14.52?

When you install Visual Studio (using any channel) and select the Desktop development with C++ workload, you only get the default MSVC toolset.

To install the 'latest preview' you need to run the Visual Studio installer and select the MSVC Build Tools for <arch> (Preview)
