Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

iOS / iPadOS 17 👉 Blink 17
Fixes for the new OS, general improvements, and tons of thanks to all testers for their help! https://github.com/blinksh/blink/discussions/1850

Apple debuts iPhone 15 and iPhone 15 Plus
You can already do that with an iPad (sans fat OS). If you're using Blink Shell (https://blink.sh) the external display is independent of what's on the iPad too, which works really neatly. This is the exact setup I used as my main dev machine in a previous role.
Would be very nice to see if this works on the new iPhones. A thin client with decent security in your pocket with keyboard/mouse/display at both home and work seems like a very approachable computing setup.

Apple iPhone 15 Pro and iPhone 15 Pro Max
I use blink[0] with a 40% keyboard to develop linux program on a vps.
If you want to do programming without wireless interenet, another option is to connect a raspberry pi zero 2w (with usb gadget mode enabled) to the usb c port using a single usb cable. Then the rpi zero will share a ethernet network with iOS device. Then you can use blink (again) to mosh to raspberrypi.local to do the development on the pi.
The reason that I don't do it on android with termux is that there's no high quality terminal emulator like blink on android.

Buying an iPad Pro for coding was a mistake
There's also Blink [1] which includes a local shell (limited), ssh and mosh support, and comes with a local-first, but remote-dependent, vscode implementation. Works with vscode.dev, code-server (the coder.com and microsoft version), coder.com etc. Not free but a free TestFlight versions available if you accept to be a beta tester of sorts.
I've had moderate success using it, but overall the code-server experience has been a bit lacking, in part due to languages I use, in part due to lots of software still assuming a local-first development environment (code-server/coder.com help with this by e.g. proxying http ports in your dev environment). A real IDE/code editor running on a MacBook is still way superior.

Prompt2, heads up; they are readying up another version Prompt2 has been abandoned by devs since iOS 14 / 1y ago in a crashing state - Now they want to make another money-heist cash-grab from its users by forcing them to upgrade one of the most expensive apps of all time.
If you're okay with a subscription model for a terminal type shell, I would recommend Blink. Does everything Prompt did and more. They have a 1-week trial, and then you can subscribe for $20 a year.

Github code no longer updated?
I also opened https://github.com/blinksh/blink/issues/1777 so from now on everyone is able to see the commit reference that was used for the build.

Ed25519-sk on iOS
I took a wild stab at finding a non-subscription iOS app that supports Ed25519-sk, but ended up just moving back to ephemeral per-device ed25519 keys instead. Both Blink.sh and Terminus purport to support -sk / HW passkeys behind subscription paywalls, but I can't verify as I don't pay for subscription model apps.

Ask HN: What lesser-known accessories do you use with your computer?
SSH or mosh (via https://blink.sh/) back to a cloud/remote NixOS VM. The iPad is purely a self-contained interface with a local browser.

What if null was an Object in Java?
At least on android arm64, looks like a `dmb ishst` is emitted after the constructor, which allows future loads to not need an explicit barrier. Removing `final` from the field causes that barrier to not be emitted.

3rd Edition of Programming: Principles and Practice Using C++ by Stroustrup
You said You won't get "extreme performance" from C++ because it is buried under the weight of decades of compatibility hacks.
Now your whole comment is about vector behavior. You haven't talked about what 'decades of compatibility hacks' are holding back performance. Whatever behavior you want from a vector is not a language limitation.
You could write your own vector and be done with it, although I'm still not sure what you mean, since once you reserve capacity a vector still doubles capacity when you overrun it. The reason this is never a performance obstacle is that if you're going to use more memory anyway, you reserve more up front. This is what any normal programmer does and they move on.
Show what you mean here:
https://godbolt.org/
I've never used ISPC. It's somewhat interesting although since it's Intel focused of course it's not actually portable.
I guess now the goal posts are shifting. First it was that "C++ as a language has performance limitations" now it's "rust has a vector that has a function I want and also I want SIMD stuff that doesn't exist. It does exist? not like that!"
Try to stay on track. You said there were "decades of compatibility hacks" holding back C++ performance then you went down a rabbit hole that has nothing to do with supporting that.

C++ Insights – See your source code with the eyes of a compiler
C++ Insights is available online at https://cppinsights.io/
It is also available at a touch of a button within the most excellent https://godbolt.org/
along side the button that takes your code sample to https://quick-bench.com/
Those sites and https://cppreference.com/ are what I'm using constantly while coding.
I recently discovered https://whitebox.systems/ It's a local app with a $69 one-time charge. And, it only really works with "C With Classes" style functions. But, it looks promising as another productivity boost.

Ask HN: How can I learn about performance optimization?
[P&H RISC] https://www.google.com/books/edition/_/e8DvDwAAQBAJ
Compiler Explorer by Matt Godbolt [Godbolt] can help better understand what code a compiler generates under different circumstances.
[Godbolt] https://godbolt.org
The official CPU architecture manuals from CPU vendors are surprisingly readable and information-rich. I only read the fragments that I need or that I am interested in and move on. Here is the Intel’s one [Intel]. I use the Combined Volume Set, which is a huge PDF comprising all the ten volumes. It is easier to search in when it’s all in one file. I can open several copies on different pages to make navigation easier.
Intel also has a whole optimization reference manual [Intel] (scroll down, it’s all on the same page). The manual helps understand what exactly the CPU is doing.
[Intel] https://www.intel.com/content/www/us/en/developer/articles/t...
Personally, I believe in automated benchmarks that measure end-to-end what is actually important and notify you when a change impacts performance for the worse.

Free MIT Course: Performance Engineering of Software Systems
resources were extra useful when building deeper intuitions about GPU performance for ML models at work and in graduate school.
- CMU's "Deep Learning Systems" Course is hosted online and has YouTube lectures online. While not generally relevant to software performance, it is especially useful for engineers interested in building strong fundamentals that will serve them well when taking ML models into production environments: https://dlsyscourse.org/
- Compiler Explorer is a tool that allows you easily input some code in and check how the assembly output maps to the source. I think this is exceptionally useful for beginner/intermediate programmers who are familiar with one compiled high-level language and have not been exposed to reading lots of assembly. It is also great for testing how different compiler flags affect assembly output. Many people used to coding in C and C++ probably know about this, but I still run into people who haven't so I share it whenever performance comes up: https://godbolt.org/

Verifying Rust Zeroize with Assembly...including portable SIMD
To really understand what's going on here we can look at the compiled assembly code. I'm working on a Mac and can do this using the objdump tool. Compiler Explorer is also a handy tool but doesn't seem to support Arm assembly which is what Rust will use when compiling on Apple Silicon.
