Blog post by waddlesplash on Sat, 2021-10-02 19:14

We already had an activity report for this month … but as I am now working on Haiku full-time thanks to the generous donations of readers like you (thank you!), a second report is in order, containing more detail on what (and some of the ‘why’) I worked on that the activity report merely summarizes.

Haiku activity report - September 2021

Blog post by PulkoMandy on Mon, 2021-09-27 08:53

Hello there, it’s time for the monthly activity report! This report covers hrev55343-hrev55451. app_server PulkoMandy reworked the way the screen is taken out of DPMS power saving mode when app_server first starts. This should have no consequences on most hardware since the screen will normally already be up during the boot screen, but the way it was implemented led to some confusion in existing drivers, as we tried to turn the screen on before the driver had a chance to set a video mode on its own.

GSoC 2021 Final Report: Coding style checker bot for Gerrit

Blog post by ritz on Sun, 2021-08-22 22:44

Hey everyone! Since the GSoC period is nearing its end therefore here’s the final report on my GSoC project Coding Style Checker Bot. Project Description: Haiku has its own coding guidelines which describe how the code should be formatted. There is a tool (haiku-format tool) for reformatting or checking if code follows these guidelines, but it has to be compiled on the developer machine and then run manually. My project was to create a Coding Style Checker bot that runs haiku-review tool on files submitted as a patchset in our code review system and posts the report in the patchset comments.

GSoC 2021 Final Report: Modernizing Chat-O-Matic (Caya)

Blog post by JadedCtrl on Thu, 2021-08-19 22:02

GSoC’s coming to an end, so it’s time for a final update: An overview of what I’ve been working on this summer. Project My project was to “modernize” and write a libpurple add-on for Caya, a multi-protocol chat program. Ultimately, I hard-forked Caya into Chat-O-Matic at the request of a previous maintainer― with the name being suggested by win8linux. :-) “Modernization” here means three things: Allowing multiple accounts in use at once, re-orienting the program to support multi-user chats, and giving add-ons some more flexibility.

GSoC 2021 Improvements to Haiku-format Final update

Blog post by saloni on Wed, 2021-08-18 12:07

GSoC 2021 Improvements to Haiku-format Final update It has rightly been said - “All good things come to an end”. Google Summer of Code too was one of the good experiences I’ve had, in the sense that I didn’t know anything about the Open Source world. It provided the exact platform that I needed to kickstart my open source contributions. About my project: Haiku has its own coding standards which describe how the code should be formatted.

20 Years of Haiku

Dedication asks each of its adherents to have faith even as time and energy pass through from one year to the next. Dedication brings with it a variety of challenges, but also rewards. Dedication is something most people claim to have, but few readily exhibit it in the face of adversity. As of today, Aug. 18, 2021, the Haiku Project is celebrating two decades of dedication, marking the 20th anniversary of the founding of the Haiku operating system and the start of this ride to save, maintain, and expand upon the BeOS legacy it spawned from.

Positively Critical: WebPositive and Haiku

Blog post by Animortis on Tue, 2021-08-10 18:55

Few components of Haiku are as important to the operating system and its functionality as the preferred web browser and internal project: WebPositive. In recent days, some users have expressed concern about a “disappearing text” bug, where some text on web pages will disappear for undetermined reasons. This issue is now fixed, but highlights the reason why WebPositive is so important. The history of WebPositive is as intricately woven into Haiku as BeOS was, and has served as a major effort for all the programmers and users of the operating system even as other web browsers are successfully ported, work for a little while, then, unfortunately, lose functionality and are abandoned.
