Haiku Contract Report: December 2021

Blog post by waddlesplash on Mon, 2022-01-10 18:00

For the first time, most of the work I did as part of this contract was not in the month’s activity report aside from a passing reference, as nearly all of it took place outside the main Haiku source tree. So, here I detail it; and thanks once again to the generous donations of readers like you (thank you!).

Haiku, Inc. Financial Reports for 2020 and 2021 are now available

News posted on Sun, 2022-01-09 22:00

The Haiku, Inc. financial reports for 2020 and 2021 are now available on the Haiku, Inc. Documents page. There is also a forum post with a bit more details, which also explains why the 2020 report was so late and the 2021 report was so early. Our donations for 2022 are off to a great start with over $2,000 donated so far, and we are not even 10 days into the year.

Haiku activity report - December 2021

Blog post by PulkoMandy on Thu, 2022-01-06 08:53

Happy new year! Note: this report covers changes only to the Haiku main git repository. There are many other things going on for Haiku outside that git repository. In recent big news, we have an X11 compatibility layer, and a running experimental Wine port. However, I cannot cover everything in these reports. Help welcome if you want to contribute to our website with news announcements for such items. That being said, let’s see what’s going on in Haiku itself!

Haiku Contract Report: November 2021

Blog post by waddlesplash on Thu, 2021-12-09 21:00

PulkoMandy has already written the activity report for this month, so now I am once again left to detail the work I have been doing thanks to the generous donations of readers like you (thank you!).

Haiku activity report - November 2021

Blog post by PulkoMandy on Thu, 2021-12-02 08:53

Hello there, it’s time for the monthly activity report! This report covers hrev55609-hrev55687. New architectures Kallisti5 fixed some minor problems with the PowerPC port to keep it building and simplify it a bit. Kallisti5 and waddlesplash also continued cleaning up the RISC-V sources and fixing various minor issues there. David Karoly is making progress on the 32bit ARM port, using EFI as a boot method. The previous attempts for an ARM port used the linux style booting, where the firmware bootloader (usually uboot) only does the minimal hardware initialization, and then hands over complete control to the operating system.

Media Release: The Haiku Project and Freewear launch Official Haiku Merchandise

News posted on Wed, 2021-12-01 12:17

The Haiku Project launched its official merchandise today in partnership with FreeWear, an online free and open-source software (FOSS) merchandising store and print shop. The partnership will allow The Haiku Project to offer a new way for people to financially contribute to the development of Haiku whilst getting a physical item in return for their gratitude. Donations greatly contribute to initiatives such as the recent development contract, which is allowing waddlesplash, a respected Haiku contributor, to make further general improvements to Haiku, such as system improvements, new and refined drivers and more.

Booting our RISC-V images

Blog post by kallisti5 on Sun, 2021-11-07 07:29

Thanks in large part to the hard work by X512 and everyone developing on Haiku, our nightly RISCV64 images are now functional. RISC-V marks Haiku’s first functional non-Intel/x86 port! What is RISC-V? RISC-V is a modern, fully open CPU instruction set which can be implemented, customized, extended, and sold without royalties. Designs exist for a 32-bit, 64-bit, and even a 128-bit processor design. You can emulate RISC-V in qemu, design your own CPU and synthesize it for an FPGA, or you can purchase a commercially built and designed computer with a RISC-V processor.

Haiku Contract Report: October 2021

Blog post by waddlesplash on Thu, 2021-11-04 21:00

Just like last month, while we already had an activity report, the work I have been doing thanks to the generous donations of readers like you (thank you!) deserves its own report.

Haiku activity report - October 2021

Blog post by PulkoMandy on Mon, 2021-11-01 08:53

Hello there, it’s time for the monthly activity report! This report covers hrev55452-hrev55608. Kernel Waddlesplash made the kernel always build with gcc8, even on 32bit systems. It was built with gcc2 until now, but it was not possible to use BeOS drivers anymore since the introduction of SMAP and other features, which led to slight changes in the driver ABI. No one complained, so there is no reason to preserve BeOS driver compatibility further.

OK Lenovo, we need to talk!

Blog post by mmu_man on Wed, 2021-10-20 16:00

I’ve been wanting to publicly comment on Lenovo’s statement on Linux support for a while, as there’s much to say about it, and my failing attempt at finding a suitable replacement for my venerable T510 gave me an excuse to document my love-hate relationship with Lenovo all at once.

This is of course my own personal views and ideas, and does not reflect the Haiku project’s position on the topic, nor that of Haiku, Inc. But I feel they deserve to be brought here due to history and the direct and indirect effect it might have had on the project, including previous failed attempts at commercial applications using it.

While Lenovo is still above many other manufacturers on some aspects, and on others domains, well, nobody does any better anyway, they purport to perpetuating the IBM legacy, so I think (sic) they should be held up to the standard they claim to follow. Yet the discussion about repair and documentation pertains to almost every vendor.
