What I did over the past week XX

Home:

  • Upgraded ShaftNet to Fedora 32. Fixed most of the fallout.

    • Traced and labeled all of the RG6 coax drops in the house
    • Installed a new splitter and cleaned up the wires where they all terminate.
    • MoCA adapters installed in the media center and master bedroom.
    • Attached nearly all 2.4GHz-only devices to the MoCA bridges.
  • Cleaned the gutters again, and swept up nearly 100 cubic feet of leaves.
  • Dishwasher died mid-cycle; turned out to be an internal fuse. Replaced it, the loose handle, and re-leveled the whole thing.

Vehicular Stuff:

  • Installed the replacement dome light on the Kubota. I really need to pick up an inline fuse.

Rockbox:

  • Added the necessary librares to enable interfacing with the bluetooth subsystem on HibyOS-based targets.
  • Update configure script to prompt for USB serial support when in advanced mode.
  • Cleaned out some long-deprecated language strings.
  • Bugfixes for USB action prompt on some targets.
  • Improved ALSA PCM driver to reduce (and better mitigate) buffer underruns.
  • Minor xDuoo X3 manual fixes.
  • Fixed HTML manual generation with modern Tex Live packages.
  • Infrastructure improvements:
    • Buildserver now uses 10-character commit IDs internally.
    • Improved metadata generation for the upcoming Rockbox Utility release.
    • Rearranged where daily builds, voices, and manual files are placed.
    • Nightly build scripts now generate a font package.

Photo Organizer:

  • Minor changes for better PHP 7.4 compatibility; Now requires at least PHP 5.4!

Printing:

  • Bugfixes affecting the Sony UP-DR200 (and probably other older UP-series models).

What I did over the past week XIX

Home:

  • Cleaned out the gutters (again), and swept up three more loads of leaves.
  • Hauled off another 10 bags of leaves (total of 30 so far)

Vehicular Stuff:

  • Wired up a waterproof LED dome light on the Kubota, and had to remove it the next day as it turned out to be defective.
  • Discovered the Subaru was low on both oil and coolant. Sigh...
  • Picked up and installed a new wheel splash shield for the Prius; the old one was shredded by a hidden stump.

Rockbox-specific:

  • Further cleanup of the PCM API.
  • Explicitly clear all pending button events when entering Yes/No popup.
  • Configurable action upon on USB insertion, including prompting the user.
  • Some plaform-level fixes for the iBasso DX50/DX90.
  • Fixed a pile of minor bugs with the www site scripts.
  • Upgraded gerrit instance to v2.16.23, fixing a longstanding site config problem along the way.
  • Wrote up a privacy policy, and added a link to the site templates.
  • Made some quality-of-life improvements in the admin mode on the themesite.
  • Cleaned out obsoleted/superseded themes, shrinking the DB size by nearly 2/3rds and about 100MB of disk space.
  • Reviewed some patches.

What I did over the past week XVIII

Home:

  • Replaced kitchen faucet and installed a drinking water filter. This was a real PITA due to limited access and seized bolts. I ended up using a dremel to cut off the supply lines, and an angle grinder to take off the faucet from the top. Unfortunatlely, I managed to gouge the sink in the process. It was already pretty beat up so it's not the end of the world.
  • More yard work! Literally hammered the leaf sweeper back into working condition, cleaned out the gutters yet again, swept up several more loads of leaves, and hauled off the first 20 bags of this new season before Eta's effects began to hit us.

Vehicular Stuff:

  • Replaced the Kubota's taillights with standard 6" oval LED fixtures, for much improved nighttime visibility. Daytime too, as the old bulbs were pretty dinky.

Rockbox-specific:

  • Got rid of last python2 scripts involved in www site.
  • Addeed a heuristic to determine if ATA devices are actually solid-state.
  • Updated a 7-year-old patch for iPods to restore factory hard drive timings, but made it apply only when solid-state drives were in use.
  • Nuked a few more remnants of the old Archos players.
  • Fixed a scrollwheel regression on the Eros Q and clones.
  • A little progress on the Patch / Bug backlog.

Sony UP-D898 family working!

241106:362363

I got my hands on a UP-D898MD on Thursday, and after some head-scratching bugfixing, I'm pleased to say it now works reasonably well under Linux, incluidng custom print sizes and status reporting.

It's worth noting that other the other members of the '898 family (the non-MD versions, as well as the UP-X898 and UP-D898DC) might have their own quirks, but only time will tell.

There are still some missing features I haven't yet figured out -- For example, how to control the copy count and things like brightness/contrast from the host side.

Along the way, I landed bugfixes that affect other "Sony UPD Neo" printers (such as the UP-DR80MD and UP-CR20L).

To take advantage of this support, you'll need to grab Gutenprint out of git (or a snapshot/release dated after 2020-11-07).

Oh, the aptly-chosen test print is from Episode 91 of Sanesparza's "How To: Comics"

Update 2020-11-08: Fixed copy count

Autumn light

I missed the awesome light by about 45 seconds, but it still looks nice enough.

Incidently, this is the first recrational photo I've taken since New Year's.

What I did over the past week XVII

Wow, four months of these weekly updates!

Home:

  • Replaced the fuel line and filter on the leaf blower. Now starts and runs a lot better, but can't sustain full throttle. It's a net improvement, but I will have to put that diagnosis off until next weekend.

  • Added another shelf to the server rack, relocated all of my test equipment onto it, and tidied up more of the wiring.

  • Upgraded the beastly server and my workstation to Fedora 33.

Vehicular Stuff:

  • Oil change on the Prius. Made a huge mess, and had to degrease the driveway afterwards
  • Re-mounted the Subaru's rear view mirror the day after it fell off. Again.

Rockbox-specific:

  • Bumped arm and m68k targets to use the same GCC 4.9.4 toolchain used by all other targets. Cleaned up the mess that ensued. mostly in various bootloader builds. (This was more than six months in the making; now we need to make sure there are no regressions..)

What I did over the past week XIII

Fall has arrived, bringing a bout of very Seattle-esque weather. But I kept the blahs away by getting a lot done!

Home:

  • Hauled away another 10 bags of leaves from the pile (total: 80), and swept up another load. Rain prevented any additional work.
  • Cleaned the gutters and the driveway
  • Installed another shelf in a wardrobe
  • Completely emptied out a large tub of old computer stuff, organizing the worthwhile bits and throwing out the rest. All that remains is to tidy up one final cable snarl.
  • Purchased a "New Model M" keyboard from Unicomp to replace the 25-year-old M that was murdered by a glass of Orange juice just before the COVID lockdown started. The Cherry keyboard I was using in the mean time was decent, but.. the M remains the best keyboard I've ever used. Meanwhile, the 27-year-old M that I've used for every job of my career remains locked away in the inaccessible $dayjob lab.

Vehicular Stuff:

  • Found a large nail in the tire of the RTV while doing yard work, but it didn't actually puncture the knobby off-road tires.
