  • I don’t think there’s anything commercially available that can do it.

    However, as an experiment, you could:

    • Get a group of photos from a burst shot
    • Encode them as individual frames using a modern video codec using, eg VLC.
    • See what kind of file size you get with the resulting video output.
    • See what artifacts are introduced when you play with encoder settings.

    You could probably/eventually script this kind of operation if you have software that can automatically identify and group images.



  • True. Hence my caveat of “most cards”. If it’s got LEDs on the port, it’s quite likely to signal which speed it is at with those LEDs.

    I haven’t yet come across a gigabit card that won’t do 10Mbit (edit: switches are a different matter) but sometimes I’ve come across cards that fail to negotiate speeds correctly, eg trying for gigabit when they only actually have a 4 wire connection that can support 100Mbit. Forcing the card to the “correct” speed makes them work.

    1. Replace CMOS battery.
    2. Get small UPS.
    3. Discover that small UPS’s fail regularly, usually with cooked batteries.
    4. Add maintenance routine for UPS battery.
    5. Begin to wonder if this is really worth it when the rest of the house has no power during an outage.
    6. Get small generator.
    7. Discover that small generators also need maintenance and exercise.
    8. Decide to get a whole house battery backup a-la Tesla Powerwall topped off by solar and a dedicated generator.
    9. Spend 15 years paying this off while wondering if the payback was really worth it, because you can count on one hand the number of extended power outages in that time.
    10. In the end times a roving band of thugs comes around and kills you and strips your house of valuable technology, leaving your homelab setup behind and - sadly - without power. Your dream of unlimited availability has all been for nought.

    Conclusion: just replace the CMOS battery on a yearly basis during planned system downtime.



  • What if I want to buy a cheese sandwich today with BTC?

    A cheese sandwich can remain the same fixed price in dollars for years, with only the relatively slow change in actual value due to inflation.

    I’ve seen BTC swing 10% in 24 hours. Does the cheese-sandwich-maker have to look up the rate this instant and calculate a spot price for me?

    Will they have more or less dollars at the end of the day, when they need to pay their bills and buy more cheese from their suppliers?

    “Just buy cheese from someone who takes BTC”, doesn’t help, it just kicks the can further down the road.

    “Just add a bit of a buffer in the price to take fluctuations into account”, means that I go buy a cheese sandwich with dollars from next door because it’s 50 cents cheaper for the same thing.

    As an investment vehicle, BTC is doing hot laps of the track (with occasional accidents), but until its volatility issues are sorted and it becomes “boring”, it’s not going anywhere as an actual currency.



  • I end up having to play twenty questions with chatgpt. For example, I’ve been asking it for code examples for ffmpeg mpeg4 encoding with C++.

    It will happily spit out completely non-working code, where the core part - feeding image frames to the encoder - works, but it doesn’t initialise or tidy up the encoding afterwards.

    Until I say, “hey this code doesn’t seem to work and creates corrupted files”, and then it’s like, “oh yeah you also need to do a bunch of other stuff, just like this”. Repeat as it slowly adds more and more pieces until finally you end up with something that actually works.

    Or it will happily dream up function names or mix python and C functions, or will refer to older APIs even when I’ve specifically said “use API version x.y” and so on and so forth.

    If I didn’t know enough about the subject already, I’d never be able to tease out the answer. So in a sense it’s a mostly useful reference, but it can’t be relied on to actually and consistently provide a result because it’s all statistics and fuzzy text generation behind the scenes, not actual knowledge.







  • Having SSD dram allows the SSD to say “done” sooner to the OS despite it taking the same total time.

    That’s exactly why. When writing to a drive the OS waits until the disk says “done” and then goes about it’s business.

    If the drive then takes an extra bit of time internally to write to permanent storage that’s none of the OS’s business as long as it can pull that written data from “somewhere” and deliver it to the OS if asked.


  • And he describes exactly what I have to deal with on the regular, “content that only sort of helps”

    Hello, my name’s dgriffith. I’m a Fediverse Support community member, and I’m here to help.

    Have you tried running sfc /scannow and making sure your antivirus is up to date? That usually fixes the issue that you are describing.

    If that does not help, a complete system reinstall often solves the problem you have.

    Please mark this comment as useful if it helps you.

    Regarding the death of hyperlinks, it’s probably more a case of “why bother clicking on yet another link that leads me to another page of crap?”.

    That is, it used to be the case that you’d put information on the web that was useful and people would link to it, now 80 percent of it seems to be variations of my “helpful” text above, SEO’d recipe sites, or just AI hallucinations of stuff scraped from other sites.


  • I have an Oki laser printer that I bought for $129. I’ve had it so long I gave it to my kids for university. Duplex, wifi, and I’ve bought two toner cartridges for it in the 8 years we’ve had it.

    (Side note: If you go to an airport, you’ll find that the dot matrix printer spewing out the passenger manifest at the gate is often a Okidata Microline-series printer, an updated version of the printer I had in 1992)

    Basically, don’t buy an inkjet printer, and don’t buy HP.


  • North east coast of Australia gets hit with category 5 cyclones every 5 to 10 years or so, there are plenty of buildings that survive that.

    Parents copped the brunt of Cyclone Yasi with 180 mph gusts, only damage to their house was they lost a section of guttering, it was peeled off never to be seen again.

    Building standards there are rigorous. They built their house themselves (in a rural area, 180 acre farms), its engineering design was required to withstand wind loadings of at least 70m/s (160mph) .

    It is a steel-framed, single story kit home, on a steel piling foundation about 3 feet off the ground. The local building inspector also told them to put long threaded rods from the roofing trusses to the subfloor and the foundations while building it and tension them up, they eventually put in 36. This effectively ties the roof to the foundation and stops it peeling off, once your roof comes off the rest of the house usually folds up like an open cardboard box.

    Apart from losing the section of guttering, there was no other damage to the house. They boarded up the larger glass sliding doors and were somewhat alarmed at the amount of flex on the glass as the cyclone passed, but they held up ok. They didn’t get power back for two weeks , which was the worst of it for them as it’s very humid afterwards, they had a generator and ran it in the evening to power the aircon in their bedroom each night until it ran out of fuel.
