Re: 24" monitors.. 1920x1080 or 1920x1200 ?

@Raziel

Did you try using the higher res but increasing font size slightly? You might find you get a bit more space but still maintain readability.

That's more or less what I've done every time I've upgradrd my monitor size (okay that's maybe on twice ,...) double the res, increase font point by factor off 1.5. Sharper fonts you can still read.

Re: OS4 pthread.library usage experience wanted

@Hans

Strictly I found one issue in two places. Under some hard to reproduce conditions a pthread and it;s parent thread can both seem to end up waitng for a semaphore. It's hard to reproduce in terms of a simple code example that I can give to Rogue to test. (I must try to have another go at that soon, just can't find any programming time ATM.) not so hard to get to happen.

It seems to occur when new threads are being spawn at the same time as another tasking is using lot's of or a surge of cpu time. Such as rendering an animation with blender (make lost of pthreads) and browseing the net, sudden surges of image decoding.

The threading thing that's really giveing me problem in blender at the moment, is the SDL_Audio thread, which blender tries to kill on exit, fails and goes into a busy loop. This is an "SDL thread" and nothing to do with pthreads though.

@abalaban

I would say if you are porting existing code that uses pthreads then, use pthreads under OS4. Otherwise unless you need something specific from the pthread API write your own code using amigaos tasks and stuff.

I don't think there any limt on what you can do WRT the AmigaOS API in a pthread. You may have to be careful about altering task user data perhaps, as pthreads might use that (not 100% sure on that but I think I 'read it somewhere TM')

@amigadad

Hang on, you installed from one CD only and no internet? Most likely you have only a base install.

Try connecting to the net and running Tasksel it should offer you options like desktop environment.

@DaveP

The only potential problem with atexit() is that there is a limit to the number of functions you can register, the specification specifies at least 32. No ideas what the practical limit for amigaos clibraries is ....

It's always called on exit unless you call abort()

@freddix

exit() will do this for you, it quits the program exactly as if you'd come to end of main.

Should you require any additional cleanup, ie freeing non Clibrary resources such as amigaos libraries opened by the directly program, memory allocated directly with exec.library then create a cleanup function and pass it to atexit(). It will then be called when you call exit() or when you fall through main().

http://www.cplusplus.com/reference/clibrary/cstdlib/exit/

http://www.cplusplus.com/reference/clibrary/cstdlib/atexit/

You should avoid abort() though as this does no cleanup and should only be called when something has gone very badly wrong.

I think we would all prefer ARexx to fade away into the sunset and be replaced by Python. AFAIK the OS4.1 Installer is written in Python (but no first-hand knowledge).

Trouble is the current python arexx.so module does not set or extract the equivalent of ARexx's RESULT variable, so is very limited when interacting with programs arexx ports.

It would of course save "all" (both) of the calling apps from implementing that logic, but at the cost of having to load the full CDM executable from disk every time you click on some download link, just to make it send the download details to the already running instance and die.

Hmm, were talking small utility here though? Not major app. So simplicty of API would outway the startup load issue?

"small utility" is in no way derogative, I'm imagineing a lean efficient implementation. If it followed the AWeb model I mention aboth the check for multiple instances would occur before any external libraies were reoppened.

BTW which two apps constitue "both" ?

OWB starts up, you click on download a link with a download manager, it checks to see if the CDM is started (public message port active), and if not, calls for CDM to be started.

Wouldn't it be better if the CDM did that itself? ie when a new instance is started it check for it own message port and passes any args onto an existing copy. (that's how aweb handles multiple startups anyway)

Quote:

Well, after having used Blender on the PC, I can say that it's definitely not a replacement for Lightwave. It's really difficult to get it to do even simple things, I can't imagine doing serious projects with it. It has a very steep learning curve.

I've never used Lightwave so can't compare with that, but I found blender tricky compared with Imagine for a while. But once used to it, I've got a few quite complex projects underway, including a complex animation of a cartoon character playing guitar, currently I've spent so much time trying to get it working under OS4 that my projects have been largely aborted, but I have blender in a workable state now, can't release yet due dependencies on pending fixes in minigl etc. Given that it's free you'll not see anything better for while I think....

@orgin

Not sure, but maybe it's the buffersize in IDOS->FOpen() that you would need to increase? Although unhelpfully It says 0 = default in the autodocs without specifying what that default is.

The COPY command docs says it uses a default buffer of 200 x 512 byte blocks so perhaps that is a guide.

[edit]
I notice that DOS prefs has a filehandle bufsize entry and that is only 8kb.
So presumably that is the default refered too.
[/edit]

To honest though, filer seems to copy moderately fast for me, faster would obviously be better but it's not problemetically slow here.

Re: SGrab and OS4.1

@my_pc_is_amiga

I think the trick is to ensure that window you want to grab is active before you bring sgrab using the hotkey. Then when you press grab, the sgrab window disappears and your window reactivates. If you activate your window after bringing up Sgrab than it may not reactivate when Sgrab does the grab.

What apps are you using.

Mainly Firefox + flash at the moment as my linux inxtall has been really stripped down, also Cheese WebCam Booth.

Both work better via X type connections under linux, (when compared to VNC).

I would occasionally use blender but it won't work via VNC and it might as well not work via X (slow is not the word in this case!!!)

I also access remote shells more easily via VNC rather than ssh (except that I start VNC via ssh) as it easier to use sh with a unix console. This is usually for starting remote blender renders on the slightly faster machine.

Comparing speed of X11 to VNC isn't ``fair''. It is like comparing playback of movie on two devices, while 1-st uses framedrop (vnc) and othe struggles to draw every frame (X11).

Hmm but in the linux to linux situation

debianx86_Xclient to debianppc_Xserver

is much faster than

debianx86_Xclient to debianx86_XVNC to debianppc_vncviewer

That could be because XVNC is loading the p3 server in addition to the app.

Speeds on TwinVNC under amigaos4 and vncviewer under debianppc are comparable (OS4 might even have the edge)

Quote:

Comparing AmiCygnix to debian's xserver is unfair too (older totally unaccelerated version vs. one with accelerated 2d driver without extra software layer that exists in AmiCygnix' case. )

I don't expect AmiCygnix to go as fast as linux, I just need to to be faster than VNC to be of use to me.

But I was under the impresion that DebianPPC on the A1 did not have hardware accelaeration enabled? (Or is that only 3d accel that's missing).

The important point about the comparison though, is that is not that X11 is faster than AmiCygnix but that X11 is faster than VNC thus a potentially optimised AmiCygnix could also be faster. If a linux native X11 server couldn't keep up with VNC there be little point in trying optimise AmiCygnix (for this purpose).

Quote:

Some things to allow faster remote display:
stop using ssh 's X11 tunneling and use xauthority mechanism
(via "xhost +client machnine" on A1 or via "Cygnix:CygnixPPC/etc/X0.hosts" and setting $DISPLAY on client machine).

I've yet to get ssh tunneling working so have always been using the method you sugest.

@ChrisH

The directory with the different skins in is called SkinFX/ is that not obvious enough for you? If you don't have that directory maybe your install is incomplete.

Having said that, there is a certain logic to explictly selecting the .xml file rather than the directory that contains it.

Oh That's interesting, hadn't notice you could do that with the skinned version. The default skin can be dragged arround by all 4 edges by the looks of it.

That feature seems to overide the ctl-alt left mouse resize a window by it edges feature though. (I hardly ever use that so I don't care just thought mention it for info sake)
