    Magewell Pro Capture card

    I’ve been kind of shifting towards use of USB devices over internal cards.

    All of the USB devices that I have still can be connected to computers. Ditto for DE-9 serial ports, though I might need a USB adapter.

    But I’ve seen ISA->PCI/AGP->PCIe obsolete a lot of old hardware that I’ve had sitting around, and that’s just on the PC. That includes my video capture hardware.



  • I doubt that this is political theater. The judge — who is a neutral party here, and introduced the question — is asking a pretty straightforward question, testing the argument that the lawyer is making. “If your argument that Trump can rebuilt the wing of the White House holds, it seems that it’d entail X (where X is something that it seems like we wouldn’t want). Is that true?”

    If you read court transcripts, this isn’t an uncommon thing for a judge to do.



  • “use a strong password” whats that gonna do if the database gets pwned, sandra?

    Strong passwords aren’t intended to simply protect against brute-forcing a password via trying to authenticate repeatedly, but also to help protect against brute-force attempts to obtain passwords from a compromised password database using a dictionary attack, the scenario you’re describing.

    Typically — if an authentication system is storing its password database competently — the password shouldn’t be stored in plain text. Instead, the password will be salted (to avoid rainbow table attacks) and then hashed via a cryptographic hash. The password database entry will look something like a tuple of (username, salt, salted hashed password). If the password is a strong one, it will be computationally-hard to obtain the plaintext password, even if someone has the salt and the salted, hashed password.


  • In March 2019, Bevin said in an interview that he deliberately exposed all nine of his children to chickenpox so they would “catch the disease and become immune.”[287]

    What year was that?

    I mean, when I was a kid, there was no chickenpox vaccine available. I didn’t even realize that we’d finally developed one until a few years ago.

    I don’t think that my parents intentionally went out of their way to expose me, though I did catch it, but intentional exposure certainly wasn’t some sort of wacko practice at the time. You were likely to catch it sooner or later, and it could be much more severe if you had it late in life — you wanted immunity earlier rather than later. Chickenpox was just kinda part of life.

    searches

    Looks like it was rolling out in the US in the mid-1990s.

    https://en.wikipedia.org/wiki/Pox_party

    Pox parties, also known as flu parties, are social activities in which children are deliberately exposed to infectious diseases such as chickenpox. Such parties originated to “get it over with” before vaccines were available for a particular illness or because childhood infection might be less severe than infection during adulthood, according to proponents.[1][2] For example, measles[3] is more dangerous to adults than to children over five years old.[1][4][5] Deliberately exposing people to diseases has since been discouraged by public health officials in favor of vaccination, which has caused a decline in the practice of pox parties,[6] although flu parties saw a resurgence in the early 2010s.[7]

    In the United States, chickenpox parties were popularized before the introduction of the varicella vaccine in 1995.[9][19][20] Children were also sometimes intentionally exposed to other common childhood illnesses, such as mumps and measles.[21] Before vaccines for these infections became available, parents regarded these diseases as almost inevitable.[21]

  • I think that the /r/place-style collaborative pixel art thing is neat.

    https://placedata.reddit.com/data/final_2023_place.png

    To be fair, that is explicitly not infinite canvas — it has finite dimensions — but there have been derived programs with infinite bounds that work the same way to do pixel art.

    It sounds like the software you’re using is intended for some kind of idea organization team stuff, though. For that, it doesn’t sound like it’s a great paradigm to me, but I also don’t spent a lot of time using software of that sort.

    I’ve used visual programming languages. These use flowcharts to represent data flow, are often used for signal processing stuff. Same kind of idea. My general feeling is that that doesn’t really scale up to large problems — you wind up wasting way too much time trying to navigate around the thing. It’s a quick and intuitive way to view very small things, though it still isn’t my preferred approach; I’d rather use text.


  • Sorry for the delay in getting back to you.

    I hope I ran the vkgears test correctly?

    Yeah, that’s fine.

    Both of those should be using hardware rendering, at least based on my understanding of the text. You have the name of your video card where “llvmpipe” would show up, right above “64bit”, which is what happens on my system when using hardware rendering.

    But…for some reason, you’re consuming a ton of CPU time when rendering using OpenGL, despite doing hardware rendering. That’s not what happens on my system. I don’t know what would cause that.

    One would want it fixed either way. For Steam, one can force Proton to use OpenGL rather than Vulkan as a Direct3D backend by setting the environment variable PROTON_USE_WINED3D=1, which will cause many Windows apps to use OpenGL…but your problem is the opposite. Vulkan looks fine.

    thinks

    The only thing that comes to mind would be that there’s an Nvidia mechanism on systems where you have multiple GPUs — this can happen when you have an integrated on-CPU GPU and a discrete GPU on a laptop, say – to render on one and then copy to the other. I don’t know what text would show up as the renderer in that case, and I don’t have Nvidia hardware, much less Nvidia hardware plus an integrated GPU to test. I don’t think that that’s probably what’s going on here, but I don’t know what mangohud reports in that case. I would think that mangohud would be smart enough to actually display the renderer being used, but…maybe it’s not. But if you want to try it, you could give this a shot. I’m taking a stab in the dark rather than really analyzing it:

    $ __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia MANGOHUD_CONFIG=full mangohud glxgears.x86_64-linux-gnu
    

    If the CPU usage when you run the above command goes from ~20% (as is currently the case for glxgears in your above screenshot) to ~4% (as is currently the case for vkgears), that might be what’s going on. If it is, then I’d try running your game with the __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia environment variables set. I wouldn’t bet much money on it working, but I guess it’s not hard to try.

    EDIT: If anyone else with an NVidia card wants to run the MANGOHUD_CONFIG=full mangohud glxgears.x86_64-linux-gnu command and report whether their system uses a ton of CPU time on all cores, that’d be a useful data point; I can’t, as I don’t have the hardware. I guess it’s possible that that the CPU usage could be normal — this is going through xwayland, and maybe something there causes that. I don’t want to flag it as something abnormal on OP’s system if it’s not. But it’s not the way my AMD system acts.




  • If you live in a big, brightly lit city and you feel like allergy season just never ends, you might be right: New research shows that light pollution prompts plants to shed pollen longer, increases the growth of notoriously allergenic ragweed and makes our bodies more prone to allergic reactions, from runny noses to asthma.

    But on the flip side, there are also going to be fewer trees in a city. That is, one might have more pollen in a city with a lot of nighttime lighting than one would relative to a less-lit city, but I doubt that one has more pollen in a city than outside cities.


  • They don’t have the means to produce at scale…steamdeck OLED

    They aren’t going to be manufacturing it themselves. They’ll pay someone else to make it.

    And I’d bet that that party isn’t limited by their own capacity, but by how many units Valve’s ordered, which is going to be limited by how many units that Valve thinks the public will buy at current elevated-by-memory-prices rates.

    EDIT: Sounds like their manufacturer is Quanta Computer, in Taiwan.

    EDIT2: And they probably aren’t constrained by their own capacity:

    https://en.wikipedia.org/wiki/Barry_Lam

    Quanta designs and manufactures for clients such as Apple Inc., Compaq, Dell, Gateway, BlackBerry Ltd., Hewlett-Packard,[13] Alienware, Cisco Systems, Fujitsu, Gericom, Lenovo, LG, Maxdata, MPC, Sharp Corporation, Siemens, Sony, Sun Microsystems, and Toshiba.[citation needed] It is the largest manufacturer of PC notebooks worldwide[14] and has diversified into servers, storage, and liquid-crystal display terminals.[15]


  • “It is, of course, possible that these multiple cases are not connected to one another,” they said, “but out of abundance of caution, we are looking into any environmental factors at the school that may be a factor in their diagnoses.”

    Although the high school was constructed in 2012, the evaluation will include research into any previous uses of the site.

    That sort of thing does seem to be a good checkbox to tick off when one is building schools.

    https://en.wikipedia.org/wiki/Love_Canal

    By the end of the 1940s, Hooker Chemical Company was searching for a place to dispose its large quantity of chemical waste. The Niagara Power and Development Company granted Hooker permission during 1942 to dump wastes into the canal. The canal was drained and lined with thick clay. Into this site, Hooker began placing 55-US-gallon (210 L) drums. In 1947, Hooker bought the canal and the 70-foot-wide (21 m) banks on either side of the canal.[16] It subsequently converted it into a 16-acre (6.5 ha) landfill.[17]

    During March 1951, the school board prepared a plan showing a school being built over the canal and listing condemnation values for each property that would need to be acquired.[22] During March 1952, the superintendent of Niagara Falls School Board inquired of Hooker with regard to purchasing the Love Canal property for the purpose of constructing a new school.

    Despite the disclaimer, the School Board began construction of the 99th Street School in its originally intended location.

    Not long after having taken control of the land, the Niagara Falls School Board proceeded to develop the land, including construction activity that substantially breached containment structures in a number of ways, allowing previously trapped chemicals to seep out.

    Over the next three decades, Love Canal attracted national attention for the public health problems originating from the former dumping of toxic waste on the grounds. This event displaced numerous families, leaving them with longstanding health issues and symptoms of high white blood cell counts and leukemia. Subsequently, the federal government passed the Superfund law in 1980. The resulting Superfund cleanup operation demolished the neighborhood, ending in 2004.

    When the state of New York stepped in to Love Canal in April 1978, 230 adults and 134 children lived in the homes with backyards directly on the canal, 410 student went to the elementary school, and 2,618 people lived in homes spread not more than four blocks from the landfill.

    Love Canal was not an isolated case. Eckardt C. Beck suggested that there are probably hundreds of similar dumpsites.[75] President Carter declared that discovering these dumpsites was “one of the grimmest discoveries of the modern era”.

    shrugs

    It’s got those faux slit windows and things made up to look like crenelations, but I’d say that it was never a fortification, as it has large, indefensible downstairs windows.

    That’ll probably place some constraints on construction timeframe, since the “manor houses styled to look like fortifications” thing only happened after wealthy people owning fortifications were a thing.


  • I’m not the best person to ask about this; I read about this mostly because of the recent rule changes. I have seen a number of financial publications writing articles about it, though.

    MSCI

    I did read one article commenting that MSCI has not changed their rules and has less-permissive inclusion rules. If you have a lot of money on the line, though, I would not take my own understanding as being authoritative (I mean, even aside from the general principle of taking statements from random unknown names on the Internet with a grain of salt; I’m explicitly not claiming to have a lot of domain expertise here).

    I think that the question is why some of the indices decided to change their rules, and whether the same logic might apply to other index operators, and I don’t know the answer to that. I’ve certainly seen many outraged people on Reddit saying that the driving factor is clearly some form of corrupt influence from company that might list on the index operator. An index operator might simply be concerned about keeping their index a useful metric that reflects market behavior — huge IPOs are market behavior. shrugs I don’t have the knowledge to say what’s a reasonable conclusion there, though I think that concern about misincentives is fair.

    I do think that it might be worth looking into if it’s something that affects you, though. There are financial publications that have people writing about this, if you want to go digging up articles on it.
