On the radar: the value of CXL (or the lack thereof):

A pre-LSFMM discussion on whether CXL memory is as wonderful as the vendors would have us believe.

@monsieuricon Public-inbox is a significant part of LWN's operation as well, definitely good stuff.

A drill with 25 CVE numbers:

Of course they only use this thing to assemble cars and airplanes and stuff...

Edited 3 months ago
Many years ago, my father set out to create a book that would help new spinal-cord-injury victims come to terms with (and love) their new life. The result, called Options, was widely distributed in rehabilitation centers for years and helped thousands of people before finally going out of print.
Inspired by the creation of the Full Circle film, which quotes extensively from the book, we have been working to bring Options back. Now, we're happy to say that Options is available, under the Creative Commons SA 4.0 license, in a number of forms. Enjoy!
As an aside, I have to say that the tools for scanning and OCR work have gotten pretty good. All of this was made possible by SANE, unpaper, tesseract, Sphinx, and surely some other tools I'm forgetting now.

@jejb Didn't miss it, even quoted a bit of it.
The funny thing being, of course, that Huawai pretty much always appears in the top-ten companies supporting kernel development:
https://lwn.net/Articles/956765/
...so they can't be entirely clueless about its origins...

Not quite sure what to make of this:
https://www.huaweicentral.com/harmonyos-next-is-true-operating-system-with-self-developed-components-huawei-ceo/
"Eventually, HarmonyOS NEXT is not an Android skin but a true OS. It doesn’t run on a primitive Linux Kernel that’s used to bind the operating system in the U.S. hands."
It's also evidently "three times more efficient than Linux"
https://www.huaweicentral.com/huaweis-self-developed-harmony-kernel-is-3-times-more-efficient-than-linux/
It must certainly be good stuff! I'm not finding a repository link, though.

@Infoseepage @mekkaokereke When we were considering the Tesla 3 we stumbled across the fact that, if the car loses power, people in the back seat are stuck there until somebody helps them from outside. That was one of the primary reasons (certainly not the only one) why we bought a Bolt instead; that has been a regret-free decision.
(OK, the battery recall was not great fun, but other than that...)

@soaproot It's called "net metering"; in essence, the electricity meter simply runs backward when the panels are generating more power than we are using. That generates a credit that we can draw on at other times.
Every state has its own arrangements, some are far better than others. Colorado is pretty good in this regard, fortunately.

It's acid-test time. Getting rid of the gas furnace and installing a #heatpump in Colorado was a bit of leap of faith, even though the consensus was that they are good enough to work in this environment now.
We're midway through a stretch of sustained sub-zero weather (as in, below 0°F, not that wimpy 0° used in other parts of the world), so we are definitely putting it to the test.
So far, so good. We did put in a backup 10KW resistance strip, that that has only come on once for a few minutes as far as I can tell. Even so, it's good that we like a cooler house than many; I think it would be hard-put to sustain the sorts of temperatures that a lot of people like to keep in their houses around here.
It *has* certainly burned through a lot of electricity; our summertime surplus from the solar panels is dwindling rapidly. The hope of getting all the way through the winter on our banked electricity seems to be falling by the wayside.
Still, the goal of turning off the fossil-fuel feed to the house remains on track.

On the radar: the 2023 year in review page (https://discussion.fedoraproject.org/t/2023-the-year-in-review/100689) on the Fedora discussion site ranks participants by the amount of time they spent reading on the site. Something there is tracking your behavior...does Fedora really need to do that?

@vegard Something weird is going on there to get numbers like that. Sphinx got a lot slower starting with 3.x, but not that much slower (about a factor of two for me).
As far as I can tell, Sphinx can only do the parsing and building of the internal tree in parallel; the HTML generation is single-threaded. So more cores only help so much. But I have no idea why you would spend over an hour waiting for something I can do in six minutes on a basic desktop machine.

@ceyusa @javierm Thanks for the concern... our experience, though, is that the sharing of subscriber links is one of the most effective forms of marketing that we have. (Of course, that may be a low bar since we don't really have anything that might be described as "marketing"). It exposes us to people who aren't normally reading our work, and some of them become subscribers, which is a good thing!

Just checked my mail and found something straight out of McMansion Hell. This delightful little place will only cost you $12 million — and you get to live in Commerce City, which is even less of a garden spot than it sounds.
(Lest you wonder, I never asked to receive this rag; they figure that if you can manage to live in Boulder, you must be part of the market for this kind of atrocity so you get it whether you want it or not.)
