Setup & Installation / Re: Panorama v Snap Video
« on: May 13, 2018, 04:33:11 pm »
You would need a second DVI interface which works together with the first one in dual link mode. We do not have any supported graphic card which can handle such thing. And TTBOMK no BIOS on this planet supports this. So no chance either with Panorama nor with current SNAP.

This is a misunderstanding, dual-links are cables with more pins, not two separate cables or interfaces, there are two emitters on the video card that are folded into one connector while a single link connector cable only has one emitter, there are lots of video interfaces out there that carry resolutions higher than 1920 x 1200 over a single dual-link DVI connector.

Just be aware that the video card may only have two emitters in total (although most AMD cards with dual-link have at the least 3), that will mean that if you use dual link the second DVI connector on your video card will stop functioning

EDIT: P.S. There is no need for driver changes to support a Dual-Link connection, allocation of emitters happens automatically in hardware.

It's just Intel's version of Software Raid, you should be using AHCI.

General Discussion / Re: The Mainframe Kid - and OS/2
« on: February 20, 2018, 11:15:04 pm »
And that is some other thing that I also wonder, what was the relationship between OS/2 Warp and the Mainframe?

There is a PC running OS/2 embedded into the mainframes that lives outside the VM, controls the boot (although they can supposedly boot without it) and also handles certain legacy communications protocols that are mostly used these days for PC to PC terminal services, configuration and administration, but it may be used for some diagnostics work as well. It is still there there in most modern mainframes or at the least the bigger ones, it was there in a 2016 model that I saw delivered via Unisys. It is simply there since the comm software layer/server was written in the 80's and updated in the mid 90's is rock solid on OS/2, an NT version did exist as well but never had the polish that the OS/2 version had, cheaper to maintain it than to start from scratch. There may be some other old custom software on there as well.

Dell Radeon X600 PCIe is slower than the X850 but still works well on OS/2, it is a half height card that shipped with brackets for both sizes and in large volumes, you will find them on auction sites with either bracket (rarely both). Only problem is that it has a DMS-59 connector so you will need a DMS to DVI or DE15 splitter cable (should come with the card but rarely does), if your monitor or monitors are HDMI only that is not a problem as the DVI signal is HDMI compatible and those dirt cheap passive DVI to HDMI converters you find just about anywhere work just fine.

here is an example:
https://www.ebay.co.uk/itm/Dell-G9184-ATI-Radeon-X600-256MB-PCI-E-DMS-59-Graphics-Card-REF-D2/362191977924?hash=item545452fdc4:g:djIAAOSwT2daOmu6

The also turn up new on ebay in bulk from time to time. Note that the Dell X600XL is a completely different card and is full height only.

#1 you're using Windows instead of Linux (NT kernel is worse at handling this than the Linux kernel)

Where do you get that info from?

I'm honestly surprised at how pro-Windows people are in this day and age when Windows was traditionally derided for being an unstable bucket of frogs (which it still is).

Its not 1995 anymore

One of the main reasons is that the KTPI fix implemented on Linux does not require PCID, which means performance won't hit pre-westmere CPUs that much. But not only that the way Windows has to work around the problem is a lot more messy due to the way Windows has everything in paged and non-paged pools--whereas this is not the case in Linux or any Unix for that matter because they're not dementedly designed like NT. Just google it, there's sources out there.

This is nonsense, and and grouping Linux and other Unix system kernels together as a block as you do here, makes no sense either as they are very different designs

Hi,

Be carrefull if you use other language than EN with accent characters. Prefer EN
I've got issue with path created having unvalid characters (frech accent in my case) which should be resolved in a futur update/release
No issue using EN.

That should not be a problem is you save as .DOC  (MS-Word), as the file is then saved with a Windows charset that is read correctly by AOO, it is files saved with a OS/2 charsets that give problems when importing to OO.

Applications / Re: Is REXX in all its versions still heavily used.

Hi David

Yes, the rexx downloads are platform specific.

I think the only rexx mentioned on rexxla that is available for OS/2 is Regina, available for download from hobbes - http://hobbes.nmsu.edu/h-search.php?key=regina&pushbutton=Search

There is a much newer version of Regina available for OS/2 than is on Hobbes:
https://sourceforge.net/projects/regina-rexx/files/regina-rexx/3.9.1/

See also the Regina homepage:
https://regina-rexx.sourceforge.io/

NetRexx also works on OS/2

This link has a rather frightening graphic from Epic Games that shows the performance hit for their servers after a patch had been applied

AMD, Arm also affected by data-leak design blunders

Two different exploits nota bene, only one ARM version affected by the same exploit as the Intel one.

The exploit that hits the PowerPC 8 & 9, PPC Z/OS and AMD FX chips is both much more difficult to exploit and can be fixed in software with no performance penalty.

P.S. Microsoft has already issued a fix for the AMD FX in their latest update package, no performance degaration.

If I am reading this correctly it only affects the chips in AMD64 mode, not the i86 mode

All those video players are ancient and will only play ancient video codecs. Really ArcaOS should just replace them with vlc but I guess as they're a traditional part of OS/2 and perhaps the deal with IBM means shipping the core OS.

They cannot distribute VLC without paying a (not insubstantial) licence fees to the DVLA and MPEGLA, same reason that no Linux or BSD distribution comes with any of those as standard but only as an download from a third party.

Yes, that is a MIDI device. However, I was thinking about a USB device with a built-in synthesizer/wavetable that generates audible output from the input MIDI stream. Much like what normal sound cards did/do.
In short: something you can throw a MIDI file at and then you can listen to some sort of sound output.
I don't know if that exists. Maybe MIDI is dead.

They exist, they are no longer a mass market option however as people have mostly moved to built in soundsets, Ketron is the biggest player in those and German company Miditech sells them as well, but Roland still has at the least one model in their lineup although that is not sold worldwide anymore but primarily in Japan and NA and Yamaha has a unit available for the Japanese market only, where GM sequencing is still a thing.

Note that the Italian site is a bit "fu*ked, their SD2 and SD1000 are excellent if a bit pricy.

http://miditech.de

These can sometimes be a bit difficult to track down as they are made in batches, they are also confusingly called "Pianoboxes".
Thomann usually have them in stock
https://www.thomann.de/gb/miditech_sound_modules_expanders.html

https://www.roland.com/us/products/mobile_studio_canvas/

If you want some cheap fun and already have a MIDI interface of some sort, track down an old Kawai G-Mega, the soundset is old-school but they go for next to nothing second hand and the built in synth is a hoot to play around with.
