Sublime Text is cross platform
Sublime Text is a proprietary text and code editor for macOS, Windows and Linux (even ChromeOS), which is very popular among developers due to a simple, fast and distraction free interface, an ability to open all the files in a folder, support for third party plugins through a package control system, extensive language syntax highlighting, and a clickable minimap view of an entire file.
Version 4 is downloadable from the makers website, Sublime HQ. There are countless changes since Sublime Text 3. The license key now includes three years of updates, rather than being tied to a specific version. This is a good change, to encourage people to keep up to date. The licence still remains valid after this time, with the last build over the three year period continuing to work. Sublime Text has always had a generous evaluation mode with a periodic nag to purchase a licence. It does not have reduced functionality for evaluation. The licence works on all platforms.
TL:DR – The competition for editors on macOS is between Sublime and BBEdit. If you need a cross platform editor Sublime wins. For MacOS only with a swiss army knife set of tools for web publishing I think BBEdit is a better choice.

You can install the Linux version on ChromeOS
Sublime Text is a proprietary text and code editor which is very popular among developers due to a simple, fast and distraction free interface, an ability to open all the files in a folder, support for third party plugins through a package control system, extensive language syntax highlighting, and a clickable minimap view of an entire file. Sublime Text runs on macOS, Linux, and Windows. Sublime Text is one of the best text editors around. Its licence keys can be shared across platforms. If you use lots of different operating systems it is beneficial to have the same editor.
Before you start!
Before you start, you'll need to ensure you have a Linux capable Chromebook. Most are! In Settings Type 'Linux' and if its there you are all set. If not, well you can try updating your Chromebook, and if it is still not there its time to get a new Chromebook.
TL:DR — Just take me to the link Sublime Text download page.

Using an SSH key, you can connect and authenticate to remote git servers without supplying your username and personal access token at each visit. Inevitably, you'll end up using more than one provider, for example for public projects and for internal private one, or for a particular client who requires a particular Git repository provider be used. SSh keys are more than just a convenient reduction in admin. They are essential in a devops environment where scripts and hooks will be working with code and multiple accounts and servers.
It is surprisingly easy to set up SSH access to Git repositories, but there are important things to think through which means you need to think about what you are doing. Most providers ofhave good instructions, and you could do no better than to start by reading one, such as this page Connecting to GitHub with SSH. The principles will be the same whatever the Git repository hosting provider.
TL:DR — SSH access to multiple Git repositories is easy to set up, convenient and secure but be careful not to accidentally overwrite other existing keys.

rsync is a file transfer program for Unix systems which has been around for decades. rsync can update whole directory trees and filesystems, can optionally preserves symbolic links, hard links, file ownership, permissions, devices and times. rsync requires no special privileges to install and can use rsh, ssh or direct sockets as the transport. Sounds ideal, but if you look at the rsync examples there is clearly quite a learning curve. This can be alleviated using grsync which provides a utilitarian but very comprehensive graphical user interface to rsync.
TL:DR — Grsync is an active project, built with GTK, which runs well on Ubuntu 21.04. It builds upon rsync which is part of the Ubuntu Linux distribution. It makes rsync easier to use for ad hoc tasks. It is licenced under the GNU General Public Licence. It is much easier to use than the rsync command line. It uses rsync of course and you can see the output from rsync if you wish.

I have relied upon Apples wireless routers since the very first Airport Base Station was released twenty years ago. I still feel that they can continue to play a decent part in my home/office network. The Airport Time Capsule ought to be ideal for cross platform file sharing between Ubuntu Linux and macOS. Lets find out if it can be made to work instead of buying a new expensive network connected drive. I ought to be able to do it, after all, I've been working on cross platform network products since the first one, 'TOPS for Mac' which connected Macs to each other and to DOS based PC's and Unix based Sun workstations in the 80's. I found a screenshot from back then of my Mac looking at connecting to my IBM PS/2 or one of several Sun workstations.
TL:DR – Still running fine, years later. I wish Apple would return to the Airport Base Station business.

Installing Flutter 2.2 on macOS Big Sur 11.3.1
Runnning a flutter 2.2 based 'Hello, world' app on macOS.
Flutter 2.0 can now create macOS Big Sur desktop apps, This is the hello world example app.
TL:DR— Getting this running took around a dozen commands, and a bit of default question answering in both Flutter and Android Studio, which you have to launch once it has been installed. It assumes you already have Xcode installed and its command line toole. It took about 15 minutes to set it up. I use a folder called 'Projects' in my home directory but you can choose whatever name makes sense for you.

As we move through 2026, the catalogue of paid add-ons for Microsoft 365 has ballooned from a handful of extras into a sprawling marketplace of hundreds of supplementary services. What began as a straightforward subscription model has quietly evolved into a tiered ecosystem where essential capabilities — security, identity management, AI assistance — increasingly sit behind additional paywalls. For finance and IT leaders trying to hold the line on software budgets, the pressure is real and growing.
TL;DR – Microsoft 365's paid add-ons have multiplied dramatically, and standard subscription tiers no longer cover many features organisations once considered baseline. From Copilot to advanced security tooling, the costs stack up fast. This article examines what's driving that expansion, what it means for your budget, and how to push back effectively — including a practical option many organisations are overlooking.
