Optimizing your QML application for compilation to C++

This is the start of a series of posts where I'm going to share some insights on how to adjust a QML application to get the most out of qmlsc, the QML Script Compiler. In contrast to previous posts, I won't talk about the abstract architecture or the high level picture.

Compiling QML to C++: Annotating JavaScript functions

This is the second installment in the series on how to adjust your QML application to take the maximum advantage of qmlsc. In the first post we've set up the environment and taken an initial measurement. I highly recommend reading that one first.

PaloAlto init-cfg.txt Bootstrap Config file Layout with Examples

When you install and configure the PaloAlto firewall, when the firewall boots up for the first time, it does the bootstrapping process. PaloAlto uses the settings defined in the bootstrap files, including the init-cfg.txt and bootstrap.xml under the config folder to configure the initial state of the firewall.

I will just quickly do a blog post...

I got ”inspired” by my writing of the previous blog post, and wrote in a channel about my experience some time ago. So why not also do a blog post about doing a blog post :) So… I was planning to use GitLab’s Pages feature via my Hugo fork as usual to push it through. So like, concentrate on writing and do a publish, right, like in good old times? I did so, but all I got both locally and in remote pipeline was stuff like…

Rust: A Critical Retrospective

Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of the Xous OS written by Xobs. Xous is a microkernel message-passing OS written in pure Rust. Its closest relative is probably QNX. Xous is written for lightweight (IoT/embedded scale) security-first platforms like Precursor that support an MMU for hardware-enforced, page-level memory protection. In the past year, we’ve managed to add a lot of features to the OS: networking (TCP/UDP/DNS), middleware graphics abstractions for modals and multi-lingual text, storage (in the form of an encrypted, plausibly deniable database called the PDDB), trusted boot, and a key management library with self-provisioning and sealing properties. One of the reasons why we decided to write our own OS instead of using an existing implementation such as SeL4, Tock, QNX, or Linux, was we wanted to really understand what every line of code was doing in our device. For Linux in particular, its source code base is so huge and so dynamic that even though it is open source, you can’t possibly audit every line in the kernel. Code changes are happening at a pace faster than any individual can audit. Thus, in addition to being home-grown, Xous is also very narrowly scoped to support just our platform, to keep as much unnecessary complexity out of the kernel as possible.

Huang: Rust: A Critical Retrospective

Andrew 'bunnie' Huang has posted an extensive review of the Rust language derived from the experience of writing "over 100k lines" of code.

Red Hat Kubernetes security report finds people are the problem

Kubernetes, despite being widely regarded as an important technology by IT leaders, continues to pose problems for those deploying it. And the problem, apparently, is us. The open source container orchestration software, being used or evaluated by 96 per cent of organizations surveyed [PDF] last year by the Cloud Native Computing Foundation, has a reputation for complexity. Witness the sarcasm: "Kubernetes is so easy to use that a company devoted solely to troubleshooting issues with it has raised $67 million," quipped Corey Quinn, chief cloud economist at IT consultancy The Duckbill Group, in a Twitter post on Monday referencing investment in a startup called Komodor. And the consequences of the software's complication can be seen in the difficulties reported by those using it.

this is a quick bash hack, to set an additional fixed ip to the user’s interface, this will (brute force) OVERWRITE all mess done by network managers of various origins: (there should be only one config file to config network settings and it is: /etc/network/interfaces, instead of 10x entities inventing it’s own standard, confusing the heck out of users, just keep the standard that is already there?)
