The release also compresses idle off-screen scrollback, with estimated memory savings of 70-90%, and raises the default scrollback limit from 10MB to 50MB. Linux changes include sharper text at fractional scaling, a rebuilt triple-buffered renderer expected to reduce tearing, movable splits that carry their processes and working directory, and revised Wayland global hotkeys using a protocol on newer Hyprland or the desktop portal elsewhere. Ghostty adds full Kitty graphics protocol support and a `+ssh` command that installs its terminfo remotely before connecting. Linux packages are supplied by distributions and community builds; the project recommends building from source. ### Source excerpt The Ubuntu 24.04 support drop is thanks to the native builds requiring some newer dependencies. Anyhow, there's more to this Ghostty release than that. ## Ubuntu firmware HWE will prevent issues on older kernel DevFeed: [Ubuntu firmware HWE will prevent issues on older kernel]() Original publisher: [Read original article]() Author: Joey Sneddon Published: 2026-10-27T23:15:24Z Content type: news Language: en Sources: [OMG!

The change is intended to reduce regressions: a firmware backport for Ubuntu 24.04's Linux 7.0 HWE kernel reportedly caused two AMD regressions on the Linux 6.9 GA kernel. Canonical would continue providing targeted fixes to both firmware sets during their respective support periods. A limitation is that only one firmware package can be installed, so devices with both GA and HWE kernels will need a workaround. HWE firmware packages were being prepared for Ubuntu 26.10, with a backport to Ubuntu 26.04 planned for early 2027. ### Source excerpt Ubuntu is planning a new linux-firmware-hwe package, in an effort to reduce the risk of firmware updates for newer kernels causing problems for users running older ones. On Ubuntu long-term support (LTS) releases, you can stick with the standard (GA) kernel it was released with for the duration of its support period, or you can install the HWE update, which brings newer Linux kernel versions to existing Ubuntu LTS releases. Right now, both kernels share the same firmware package, which means firmware updates designed to work with HWE kernels can cause problems for users who stick with the GA kernel. Ubuntu developer Juerg Haefliger noted that a firmware backport for Ubuntu 24.04 LTS, intended for its Linux 7.0 [...] You're reading Ubuntu firmware HWE will prevent issues on older kernel, a blog post from OMG!

On a Java 25.0.2 system running Ubuntu, the benchmark measured half-round-trip latency of 2.4 to 3.7 microseconds, with about 11 microseconds at the 99.999th percentile under Parallel GC. The author presents AI as useful for benchmark code and experimentation, while cautioning that business logic generally requires substantial human authorship or rewriting. ### Source excerpt While I am sceptical of using AI for release code, it has plenty of uses that previously weren't practical, such as determining how easy your software is to use. If an AI can "figure it out" with a few hints, then you are on the right track. For me, the value of AI is what you learn using it. For more Techincal Information on Chronicle-FIX What AI Does Well and What It Doesn't Claude and Codex are effective for producing idiomatic code; for low-latency code, it needs a significant body of example code. In this case, it was able to utilise sample code for benchmarks. If it was being used to write business logic, it would need the code to be mostly complete examples, and then it could write variations on that. If you were starting, it would be better to either; a) get it to write something functionally correct with the expectation you would rewrite it again manually, or b) write the code yourself and use AI to assist you in improving it. The AI Benchmark Trial I gave Codex (GPT-5.5) the task of writing a JLBH benchmark for Chronicle-FIX from documentation and sample code, testing the round-trip latency of W -> D and D -> 8 messages. The throughput is 50K/s each way. The W market data message is ~512 bytes, and the D new order signal and '8' execution reports are a small ~160 bytes. The test is run for 15 minutes each. I verified the benchmark was written but avoided hand-tuning it; then I asked it to trial different GC options, expecting they wouldn't make much difference, since the application is low GC; however, there might still be some difference. The system is using Java 25.0.2 on a Ryzen 9 9955HX3D with 64 GiB of RAM in a laptop running Ubuntu 24.04.04 LTS. A significant difference between JMH and JLBH benchmark harness is that JLBH supports many concurrent asyncrhonous inflight actions whereas JMH tests one action at a time. The Results The half-round-trip time (RTT/2) was between 2.4 and 3.7 microseconds (< 0.004 milliseconds). For the recommended Parallel GC, t ## Bringing DHH's Omakub to WSL2?

It covers default firewall policies, SSH access, service ports, IPv6, and connection restrictions for servers and desktops. ### Source excerpt A Ubuntu 24.04 LTS comes with UFW (uncomplicated firewall) that protects the desktop or server against unauthorized access. UFW is an easy-to-use frontend app for a Linux packet filtering system called Netfilter or nftables. Traditionally, Netfilter/nftables rules are set up or configured using the iptables command or nft command by developers and sysadmins. However, new Ubuntu Linux users and developers unfamiliar with firewall concepts find Netfilter/nft syntax confusing. Hence, the ufw project provides an easy-to-use frontend for Ubuntu 24.04 LTS Linux server and desktop. This quick guide makes setting up UFW on Ubuntu 24.04 LTS extremely simple. It provides step-by-step instructions for developers and sysadmins to secure their servers efficiently.
