There's a dirty rectangle algorithm in the VNC library code that compares rectangular areas from the current bitmap with the previously transmitted data and only sends the changed pixels. However, reading the whole screen to find those dirty areas is slow on some video boards (it's actually done in smaller segments to improve response time), and even slower with the BScreen copy-the-whole-screen-to-a-bitmap technique. ...

That could be an interesting way of doing it, which would also speed up screen reading since it would reside in main RAM, not the occasionally much slower video memory. On the other hand, it would be simpler for the user to understand a program that merely shows what's on the real screen, remotely. A virtual video card (RemoteHWInterface) already exists for something like this, though I don't know the details. It should be immensely useful for ...

Wasn't something like this needed in the app_server for the VirtualBox video driver? I've been trying to build the VirtualBox additions but the compile fails. Gcc complains about -fpic .

[haiku-development] Gathering info on ownership of ARM dev boards. (Richie Nyhus-Smith)

Sat, 2015-03-28 22:45
Hi all, I have done a bit of requirements elicitation [1] on the trac wiki, namely on ARM microarchitectures. Or in other words, I am trying to gather information such as developer ownership of ARM development hardware, so we can work out which devices we should try to target. It will also be helpful for people who are looking to buy an ARM board, but want to get one that is more common among Haiku developers in the hope that it will be supported sooner. ...

[haiku-development] Reading the Mouse Cursor and Dirty Screen Rectangles for VNC (Alexander G. M. Smith)

Hey guys, I'm in pretty serious need of a fix for the bug that causes instability when accessing CDs. There's been some really good discussion/brainstorming in the ticket. Now we need to circle the wagons and see if we can conquer this thing. A $750 bounty for whoever can resolve this problem. Dane ...

I think it should be an application decision. Sometimes having the text to the right doesn't make sense, sometimes it's better to have it below so the horizontal space is available for more, larger, icons. B_LABEL_BELOW B_LABEL_RIGHT ...

Sat, 2015-03-28 22:45
I'm a developer but haven't done much with Haiku as of yet. I have a few ideas for interesting kernel hacks. I think Haiku would be a good platform to test my ideas. Some of these are quite unconventional - while I will release my code to the community, I don't expect everything to actually be adopted. A problem I've had lately is that my main focus is on looking for a consulting contract, so I don't have a whole lot of time to write code. ...
