(Talospace - 10.02.2020, 06:14) It was pointed out on the Raptor discussion board that the ibmpowernv hwmon module doesn't report fan speed for Raptor family systems, and I suspect this is true for most things based on the Romulus reference design (you can only see the fan of the graphics card, and of course only if it's installed). This means most of the GNOME shell extensions to display system status won't display it. However, it is accessible by talking to the BMC over IPMI, so you should be able to get it that way. Here's a quick-and-dirty method to put your Blackbird or T2 fan speed(s) into your GNOME shel

TenFourFox FPR19 available

(TenFourFox Development - 10.02.2020, 05:36) Due to a busy work schedule and $REALLIFE, TenFourFox Feature Parity Release 19 final is just now available for testing (downloads, hashes, release notes). This version is the same as the beta except for a couple URL bar tweaks I meant to land and the outstanding security updates. If all goes well, it will go live tomorrow Pacific time in the evening. Since the new NSS is sticking nicely, FPR20 will probably be an attempt at enabling TLS 1.3, and just in time, too.

Do the brew*

(Talospace - 06.02.2020, 21:10) I've long tried to position the Talos family as an upgrade path for Power Mac owners, and here's another way: the macOS Homebrew package manager has been ported to OpenPOWER. The concept is a bit involved but most of the work has been done for you. To bootstrap Ruby requires building a version from the portable Ruby recipe, or you can borrow a ppc64le

TenFourFox FPR19b1 available

(TenFourFox Development - 28.01.2020, 07:00) TenFourFox Feature Parity Release 19 beta 1 is now available (downloads, hashes, release notes). I was originally going to do more iteration on Reader mode in FPR19, but in a possible recurrence of the issue that broke SourceForge downloads temporarily, a user reported on Tenderapp they had a site that was failing in the same way. On the test system I was able to reproduce the problem and it was due to the selected cipher having insufficient cryptographic strength to pass HTTP/2 TLS profile validation. The selected cipher was one I added as a stopgap for FPR7 to fix another site which was still working (and did not use HTTP/2, hence it didn't exhibit the issue). Disabling that cipher rest

PPC Media Center — Final Update

(PPC Luddite - 20.01.2020, 22:45) Adam Albrec decided to make one last curtain call with his Youtube gui app PPC Media Center. After six years of support he deserves one last standing-O and Bravo! and all that. Although no one can say how long the app will still work, my crystal ball tells me we can eek out at least a couple more years before Youtube or youtube-dl changes something that breaks it. This crystal ball also tells me the stock market will crash this year, but I don't know anything about that.Everything needed is included in the download link below — the base installer, the updater, and the instructive readme files.

CentOS updated to 8.1.1911

(Talospace - 17.01.2020, 01:23) CentOS has been updated to 8.1.1911, the distro for those of you who want Red Hat Enterprise Linux but don't want to pay for it. While not linked from the main AltArch Downloads page, ISOs that should be compatible with all OpenPOWER systems are available from the various mirrors. Alternatively, CentOS Stream (the Freshmaker!) is also available for ppc64le.

Bonuses for big-endian

(Talospace - 17.01.2020, 01:23) As I recover from the flu and from my apoplexy over a local plumber who has stood me up for four days in a row, there's at least some good news for those of you who like big ends and cannot lie. First, Void Linux for PowerPC reports that all available 64-bit big-endian (ppc64) and 32-bit PowerPC packages have been built, bringing them to near-parity with ppc64le. Of all total Void packages available, 32-bit ppc-musl has the lowest percentage of buildable packages, but even that is an impressively robust 88.28%. 32-bit ppc with glibc is at 88.79%, ppc64-musl at 90.15% and ppc64 at 90.49% (compare to 64-bit little-endian musl at 93.76% and glibc at 94.64%). As many 32-bit PowerPC users, particularly Power Mac owners, are looking for current supported browser options, Firefox isn't available on 32-bit (due to an xptcall

Another Amiga you don't want

(Talospace - 13.01.2020, 06:14) The Amigaphile community is possibly more rabid about its ecosystem than even us OpenPOWER dweebs, so right off I present my Amiga bona fides before getting stuck into it: in this house is a Amiga Technologies '060 A4000T running AmigaOS 3.9, an Amiga 3000 (with the tape drive, so I might even try Amix on it someday), and several A500s. My disenchantment with the current crop of PowerPC-based Amigas, however, is well-known. At their various asking prices you got embedded-class CPUs at mid-high desktop level prices with performance less than a generation-old Power Mac. (Many used and easily available m

Fedora Workstation Live ISOs up (and hopefully sticking)

(Talospace - 12.01.2020, 07:38) After a little glitch getting them off the ground, Fedora Workstation Live ISOs are now a thing for ppc64le, and are exactly what they say on the tin: a try-before-you-metaphorically-buy image to check things out before you install. A bootable disk image of Rawhide (what will currently become Fedora 32) is ready now for your entertainment and possible utility, and they should turn up as a standard download presumably when F32 goes live late April.

Firefox 72 on POWER

(Talospace - 09.01.2020, 06:18) Firefox 72 builds out of the box and uneventfully on OpenPOWER. The marquee feature this time around is picture-in-picture, which is now supported in Linux and works just fine for playing Trooper Clerks ("salsa shark! we're gonna need a bigger boat!"). The blocking of fingerprinting scripts should also be very helpful since it will reduce the amount of useless snitchy JavaScript that gets executed. The irony of that statement on a Blogger site is not lost on me, by the way. The bu

TenFourFox not vulnerable to CVE-2019-17026

(TenFourFox Development - 09.01.2020, 03:05) After doing some analysis late last night and today to determine if we need a chemspill build, I have concluded that TenFourFox is not vulnerable to CVE-2019-17026, or at least not to any of the PoCs or test cases available to me. This is the 0-day that was fixed in Firefox 72.0.1 and 68.4.1. Though a portion of the affected code exists in the TenFourFox code base, there doesn't seem to be a way to trigger the exploit due to various other missing optimizations and the oddities of our JIT. (Firefox 45-based browsers using our patches as upstream should bear in mind this may not be true for other architectures, however.) Absent evidence to the contrary it will be nevertheless patched as part of the standard security fixes in FPR19.

The new Overbite Android (works with Firefox Android too): Gopherspace on your mobile Android device

(TenFourFox Development - 08.01.2020, 06:13) Since this blog is syndicated to Planet Mozilla and I periodically post Mozilla- and Firefox-relevant posts, here is another: if you still dwell in Gopherspace and use OverbiteWX and OverbiteNX on desktop Firefox, Overbite Android has been updated to full Android Q compatibility so you can use it with Android Firefox as well. Instead of an add-on, just sideload the .apk, and whenever you tap a Gopher URL in Firefox it will automatically load in Overbite Android so you can seamlessly jump back and forth. (Or Chrome, I guess, but who uses that?) Naturally Overbite Android works just fine as a standalone application and responds to any gopher:// intent sent by any other activity, including Firefox. However, this latest version has been updated specially for Android Q support, includi

TenFourFox FPR18 available (and the classic MacOS hits Y2K20)

(TenFourFox Development - 05.01.2020, 05:33) TenFourFox Feature Parity Release 18 final is now available for testing (downloads, hashes, release notes). There are no other changes from the beta other than to update the usual certs and such. As usual, assuming no late-breaking critical bugs, it will become final Monday evening Pacific time. Meanwhile, happy new year: classic Mac systems prior to Mac OS 9 are now hit by the Y2K20 bug, where you cannot manually use the Date and Time Control Panel to set the clock to years beyond 2019 (see also Apple Technote TN1049). This does not affect any version of MacOS 9 nor Classic on OS X, and even affected versions of the classic MacOS can still maintain the correct date until Febru

And now for something completely different: The dawning of the Age of Apple Aquarius

(TenFourFox Development - 30.12.2019, 08:59) An interesting document has turned up at the Internet Archive: the specification to the Scorpius CPU, the originally intended RISC successor to the 68K Macintosh. In 1986 the 68K processor line was still going strong but showing its age, and a contingent of Apple management (famously led by then-Mac division head Jean-Louis Gassée and engineer Sam Holland) successfully persuaded then-CEO John Sculley that Apple should be master of its own fate with its own CPU. RISC was just emerging at that time, with the original MIPS R2000 CPU appearing around 1985, and was clearly where the market was going (arguably it still is, since virtually all major desktop and mobile processors are load-store at the hardware level today, even Intel); thus was the Aquarius project born. Indeed, Sculley's faith in the initiative was so great that he allocated a staff of fifty and even authorized a $15 million Cray supercomputer, which was smoothed over with investors

TenFourFox FPR18b1 available

(TenFourFox Development - 24.12.2019, 07:35) TenFourFox Feature Parity Release 18 beta 1 is now available (downloads, hashes, release notes). As promised, the biggest change in this release is to TenFourFox's Reader mode. Reader mode uses Mozilla Readability to display a stripped-down version of the page with (hopefully) the salient content, just the salient content, and no crap or cruft. This has obvious advantages for old systems like ours because Reader mode pages are smaller and substantially simpler, don't run JavaScript, and help to wallpaper over various DOM and layout deficiencies our older patched-up Firefox 45 underpinnings are starting to show a bit more. In FPR18, Reader mode has two main changes: first, it is updated to the same release used in current versions o

RIP, Chuck Peddle

(TenFourFox Development - 21.12.2019, 21:29) I never got the pleasure to have met him in person, but virtually any desktop computer owes a debt to him. Not only the computers using the the 6502 microprocessor he designed, but because the 6502 was so inexpensive (especially compared against the Intel and Motorola chips it competed with) that it made the possibility of a computer in everybody's home actually feasible. Here just in the very room I'm typing this, there is a Commodore 128D, several Commodore SX-64s (with the 8502 and 6510 respectively, variants of the 6502 with on-chip I/O ports), a Commodore KIM-1, a blue-label PET 2001, an Apple IIgs (technically with a 65816, the later WDC 16-bit variant), an Atari 2600 (6507, with a reduced address bus), an Atari Lynx (with the CMOS WDC WD65SC02), and an NEC TurboExpress (Hudson HuC6280, another modified WDC 65C02, with a primitive MMU).

Bad News

(G5 Center - 18.09.2019, 02:02) Hi, loyal readers.When I started this website, I wanted it to gather some helpful links and wisdom from my own experiences with the Power Mac G5, and I think it has succeeded in that mission. My aim too was that the site would be simple and load quickly on our PowerPC machines, while still looking modern and good. Again, mission accomplished.Unfortunately, my server is depreciating the version of PHP that the simple blog interface I am using relies upon. It's probably not wise to try to fix it. Instead, I am going to look to move the site to something different which has its own quirks and possibilities. In the meanwhile, hold your breath. The site may go down and up. It may wheeze along. There is a chance that the move is not completed by October 1, and if so, this site may throw up errors. Be patient. I'll do what I can.

Airport Extremes Are Still Useful

(G5 Center - 02.07.2019, 01:19) Buried at the bottom of one of my bits and parts bins, I have a 5th generation AirPort Extreme. I used it for a few years as my main router, but as technology changes and devices have more processing power, the Extreme couldn't keep up. It's still usable, for sure, but newer routers, for far less money, do a better job of sustaining throughput and casting a powerful wifi signal.I was reluctant to retire it because it just works, but it was time to let go.Until this week...I have used a Mac Mini G4 as a quasi-network share, but the G4 has only a 10/100 ethernet port. That gets saturated quickly, and the G4's processor probably doesn't help either. So, while it was set up and available, I didn't use it much. On the other hand, the AirPort Extreme makes a very simple Mac friendly file server with a USB hard drive plugged in. Yes, there are much speedier o
