PowerAI 1.6.0 Introduction: A Full Transition to Conda

(Linux on Power Developer Portal - 20.03.2019, 05:18) The latest version of PowerAI is here with version 1.6.0! We’ve been hard at work transforming the packaging and delivery model, updating the versions of the included frameworks and packages and adding new features. Let’s walk through the major changes in 1.6.0. Conda Packaging and the PowerAI conda channel Previous releases of PowerAI introduced interoperability […] The post PowerAI 1.6.0 Introduction: A Full Transition to Conda appeared first on Linux on Power Developer Portal.

Firefox 66 on POWER

(Talospace - 20.03.2019, 04:33) Firefox 66 builds out of the box as Firefox 65 did. In addition, as part of the porting effort, I'm running occasional check builds roughly weekly to make sure we intercept issues on nightly before they get into beta and require a higher threshold of approval for patches. So far no major issues and Mozilla continues to be very amenable to getting the occasional fixes in promptly. The biggest change in Fx66 is the number of default content processes in this release has jumped from 4 to 8. This is good news on our massively parallel multicore systems generally, but it's possible that the differing memory usage may be what tickles that harmless kernel assertion (though on the other hand, setting it back down to 4 didn't eliminate them completely). If you're on Fedora as

TenFourFox FPR13 available

(TenFourFox Development - 16.03.2019, 21:24) TenFourFox Feature Parity Release 13 final is now available for testing (downloads, hashes, release notes). I added Olga's minimp3 patch for correctness; otherwise, there are no additional changes except for several security updates and to refresh the certificate and TLD stores. As usual it will go live Monday evening Pacific time assuming no difficulties. I have three main updates in mind for TenFourFox FPR14: expanding FPR13's new AppleScript support to allow injecting JavaScript into pages (so that you can drive a web page by manipulating the DOM elements within it instead of having to rely on screen coordinates and sending UI events), adding Olga's ffmpeg framework to enable H.264 video support with a s

Life With a Low End iPad

(G5 Center - 15.03.2019, 02:27) One of my better purchases lately has not been an old Mac Pro (for under $30) or my fancy iPhone XR (which is a great phone) - it's been a basic 6th generation iPad for work. The iPad was on sale before Christmas at a local retailer, and I splurged for it as I needed it for both my school work, writing, and sermon prep. I really wanted an iPad Pro, but the price tag scared me off from that fancier device. In the end, the iPad has become a workhorse, not just for media consumption but for getting stuff done. Taking notes is fun with the original Apple Pencil, playing games is an option, and planning for work is a breeze. It's great to take on trips too and not have to lug my laptop around. In fact, I've been surprised at just how good it is for the price - around the $300 price point for the 128GB model. It's been a while since I've been so pleased from a purchase. But - I recognize it's not perfect for everyone. I do have a bluetooth keyboard I can throw into my bag on

Ubuntu LTS 14.04.6 available

(Talospace - 09.03.2019, 04:30) This is mostly relevant to our 32-bit PowerPC colleagues, but along with the recent updates to Ubuntu 16 and 18 comes what will likely be the final release of Ubuntu 14.04 LTS (read the change summary). This release is primarily security-focused, mostly to deal with the APT redirect vulnerability, though there are of course other fixes. PowerPC and POWER8 users still stuck on Ubuntu 14 should strongly consider upgrading to Ubuntu 16, which still supports 32-bit PowerPC, also supports POWER8 (but not POWER9), and is still receiving fixes as Ubuntu 14.04 will reach end of life in April 2019. Meanwhile, ISO images are available.

New Talos PowerAI SKU

(Talospace - 06.03.2019, 04:30) If you, ahem, want to see how good the POWER9 is at computer vision -- or any other kind of deep learning -- Raptor now announces a new Talos II package, the PowerAI Development System (TL2PA1). This is a T2 Lite with a 4-core CPU, 32GB RAM, 128GB NVMe flash and most notably an NVIDIA RTX 2070 GPU. Debian is pre-installed. Wait, did you say NVIDIA? Yes, because the intention with this system is to run IBM PowerAI Vision, and an NVIDIA NVLink-capable GPU is required (and so is a trial license). That automatically wouldn't make this a very good Talos workstation due to NVIDIA's historically poor open-source support (nouveau or bust since Power

Linux 5.0

(Talospace - 04.03.2019, 18:50) Linux 5.0 has been released (what used to be "4.21"). Linus is very clear that no kernel release is a feature release and the 5.0 divide is more an arbitrary numerical cutoff than anything else, but there are some important advancements in Linux 5.0 such as improved AMD GPU support, support for AMD FreeSync, file system improvements (especially to encryption performance), continued Y2038 work and various additional device support. I suspect that Talos users will find improvements to the ASpeed BMC media driver particularly relevant; my guess is this is part of the kernel support that the Blackbird is waiting on. Probably

Another choice for Intel TenFourFox users

(TenFourFox Development - 03.03.2019, 01:08) Waaaaaaay back when, I parenthetically mentioned in passing an anonymous someone(tm) trying to resurrect the then-stalled Intel port. Since then we now have a periodically updated unofficial and totally unsupported mainline Intel version, but it wasn't actually that someone who was working on it. That someone now has a release, too. @OlgaTPark's Intel TenFourFox fork is a bit unusual in that it is based on 45.9 (yes, back before the FPR releases began), so it is missing later updates in the FPR series. On the other hand, it does support Tiger (mainline Intel TenFourFox requires at least 10.5), it additionally supports several features not supported by TenFou

Ubuntu LTS 16.04.6 available

(Talospace - 01.03.2019, 18:10) Ubuntu LTS 16.04.6 is available (see the change summary for more details). Although 16.04.6 cannot boot on the Talos family, it does support POWER8, and is particularly relevant to our 32-bit PowerPC friends as it is the final Ubuntu release to support that architecture officially. All Power ISA official releases of Ubuntu are Server branded and do not install a GUI by default. Installation images are hosted at the Ubuntu download site.

Raptor, help us out here on the software side

(Talospace - 26.02.2019, 18:27) I'll preamble this with a status report on the ppc64le Firefox JIT: stalled. The stall-out is because my time is currently occupied with Mozilla bug 1512162 which has to do with the connection between JavaScript and the native representation causing debug builds to assert. I wallpapered this for Firefox 66, and that seems to be okay, but the wallpaper just seems to have moved the badness around and the issue is more fundamental. This is a more serious issue, so it's my highest priority. Unfortunately, work on this bug is getting stymied by the fact that POWER9 has hardware watchpoints disabled in the Linux kernel. Trying to catch who's writing the faulty values is nearly impossible in an application of Firefox's complexity without it because without hardware assistance gdb has to single step through the code. When you don't know even what haystack to look fo

OpenSUSE 15.1 Beta available, just not for us (yet)

(Talospace - 25.02.2019, 07:23) The beta for OpenSUSE 15.1 is now available, at least for x86_64. This isn't actually news on the ppc64(le) side because the Leap releases don't currently have a Power ISA port. However, if you want to run OpenSUSE on your Talos II, you can with the Tumbleweed releases, which is their rolling-release flavour and apparently (I'm told) works quite well on the hardware. Nevertheless, hopefully as the install base grows there will be more interest in a stable Leap release for Power ISA as well.

And now for something completely different: The G5 that went to the dark side of the X-Force

(TenFourFox Development - 24.02.2019, 00:29) My favourite console of all time is still the ahead-of-its-time Sega Dreamcast, but a close second on my list is the PowerPC-based Microsoft Xbox 360. Besides being our favourite architecture, it plays a number of great games (I still think BioShock Infinite is one of the best games ever written, and it could have been even better) and many original Xbox titles, and it's even on topic here as Microsoft shipped Power Mac G5s as development systems to early Xbox 360 developers (the X360 being powered by the Xenon CPU, designed by IBM and using three of the PowerPC PPE cores that also appeared in the Cell processor). There was a famous Anandtech article I remember where at E3 2005 they disc

TenFourFox FPR13b1 available (now with WebP and AppleScript)

(TenFourFox Development - 20.02.2019, 02:51) TenFourFox Feature Parity Release 13 beta 1 is now available (downloads, hashes, release notes). I took a different tack on this release because I still don't have good solutions for the missing JavaScript features currently affecting Citibank, Github and a few other sites, so I've chosen to push out some side projects I've been working on in order not to make this a wasted release. Those features are support for WebP images and support for AppleScript automation. WebP images are an up-and-coming format based on the WebM VP8 codec, another way Google will consume the Web from the inside out, but they do have image size advantages and Firefox now supports them in Firefox 65. Google has

So long, Opportunity rover

(TenFourFox Development - 14.02.2019, 02:38) It's time to say goodbye to another PowerPC in space, this time the Opportunity rover, also known as the Mars Exploration Rover B (or MER-1). Finally declared at end of mission today after 5,352 Mars solar days when NASA couldn't re-establish contact, it had been apparently knocked off-line by a dust storm and was unable to restart. Originally intended for a 90 Mars solar day mission, its mission became almost 60 times longer than anticipated and it traveled nearly 30 miles on the surface in total. Spirit, or MER-2, its sister unit, had previously reached end of mission in 2010. Both Opportunity and Spirit were powered by the 20MHz BAE RAD6000, a radiation-hardened version of the original IBM POWER1 RISC Single Chip CPU and the indirect ancestor of the PowerPC 601. Many PowerPC-based spacecra

XAMPP for PowerPC

(G5 Center - 02.02.2019, 04:20) If you are at all interested in hosting a simple (or complex) website or doing some experimentation from your older Mac, I do recommend grabbing the incredibly useful XAMPP to make the process a little easier. XAMPP is kind of a self-contained install of the Apache httpd server with PHP and CGI turned on, a MYSQL server, an FTP server, and some other tools and documentation. It's cool, because it comes with a little tiny app that lets you turn off the services as you see fit. You can run it when you want to try out different configurations or different websites. For Leopard, the basic Apache httpd server isn't that older than the last available XAMPP package for G5 machines. My base Leopard httpd server is 2.2.7 while the one included in the XAMPP package is 2.2.14. Still, that includes some bug fixes as well as newer versions of PHP and MySQL. If you are going to run old software, might as well run the last version of it you can find. Note: I do believe, using MacPort

Happy New Year - Broken Links

(G5 Center - 01.02.2019, 03:30) Happy New Year, fellow G5 fans! Sadly, as I look over this site, I admit that many links are now non-functional. The information here is generally still fine, but you will have to search around for working links to the apps I recommend. Some developers have likely removed older apps, even though it is handy for users of old PowerPC machines. There are some app alternative websites too, including at websites like PowerPC Software Archive. Open source apps are just a great resource in times like these, as they tend to have ready archives available for users trying to maintain ancient machines. So, hang tight. I'll be fixing links, removing some outdated software, and seeing what the future is for this website. -- Nathan

There are no additional changes except for one outstanding security update and to refresh the certificate and TLD stores. As usual it will go live Monday evening Pacific time assuming no difficulties. For "lucky" FPR13 I want to take a whack at solving issue 541, since my ability to work on Github from the G5 is seriously impaired at the moment (I have to resort to various workarounds or do tasks from the Talos II with regular Firefox). Since this has some substantial regression risk it will probably be the only JavaScript change I do for that release pending further feasibility tests on

Do things really end?

(viva PowerPC blog - 16.01.2019, 12:16) Two years ago, in my last post on this very blog, I said, that my brief PC journey ends and I'm back on PowerMac. How did it end up? Okay, I tell you the bad news right now: I'm publishing this from a Core i5 based HP EliteBook, which is at the moment my main computer. The G5 wasn't used to do anything useful at least for six months, in fact it's collecting dust in a shelf.  But don't stop reading here, let's  go back to January 2017 for an explanation... Back then I really moved back to PowerMac G5. I sold the HP desktop I had since December 2015, moved all data created on it to the G5 and simply started to use it daily as if I never left.As I mentioned in previous post, even before the move back to the G5, I replaced the failing Radeon 9800 (flashed PC version) with perfectly good Radeon 9650 (Mac version).  The 9800 served me well for over eight years, but one day it displayed only weird artiefacts on the screen and it was over.

TenFourFox FPR12b1 available

(TenFourFox Development - 14.01.2019, 05:33) TenFourFox Feature Parity 12 beta 1 is now available (downloads, hashes, release notes). As before, this is a smaller-scope release with no new features, just fixes and improvements. The big changes are a fix for CVE-2018-12404, a holdover security fix from FPR11 that also helps improve JavaScript optimization, and Raphael's hand-coded assembly language AltiVec-accelerated string matching routines with special enhancements for G5 systems. These replace the C routines I wrote using AltiVec intrinsics, which will be removed from our hacked NSPR libc source code once his versions stick. Unfortunately, we continue to accumulate difficult-to-solve JavaScript bugs. The newest one is
