    El Paso airport closed after military used new anti-drone laser to zap party balloon

    The headline is priceless. It succinctly illustrates how idiotic too many of the parties involved in this cluster-fuck actually are.

    Seven things to know about how Apple’s Creator Studio subscriptions work

    The new stand alone version of Logic changes how loops and other accessory files are stored. Before loops were in the Library as individual files and it was trivial to add non Apple loops. Now there is a single giant file that has all loops, instruments etc. As a plus, this file no longer has to...

    macOS 26 Tahoe: The Ars Technica Review

    Significant (at least for me) continued bug in the Music app. When I sync local music to my phone, compilations are all screwed up. If the compilation contains a song by an artist who is also synced in an album, multiple compilation folders are created on the phone each containing just the...

    Perpetual Random Apple Rants Thread

    I use Apple Music with local libraries as my music player. It is getting worse and worse. The biggest problem I have is how it mangles multiple libraries. I have a local library of music I regularly listen to stored on an external SSD. On other drives I also have a smaller library of tracks down...

    Tiny Vinyl is a new pocketable record format for the Spotify age

    As a novelty souvenir this might make sense but it's pretty terrible as a playback medium. Ideally for minimum distortion you want the phono cartridge exactly perpendicular to the records groove. As the angle deviates from perpendicular it introduces weird anomalies including left/right issues...

    Elon Musk sues Apple, OpenAI to block exclusive iPhone/ChatGPT integration

    This article feels very balanced, it shows that Mus is a delusional asshole without actually having to say it.

    Dear readers: Let us know what you’d like to see more of on Ars

    I love Ars but I'd prefer less cars and bicycles. Please keep up reporting on the political/tech collisions and I'd love to see more science. The in depth reports on users experiences are often fascinating. While I'm in the US, seeing more of what is happening out there in the world is truly...

    An update on highly anticipated—and elusive—Micro LED displays

    I used to specify LED walls. They were always built of modules bolted into a frame. Each module was about 75 cm tall (16:9 aspect) Depending on how close viewer were to the display and the budget we would select the dot pitch. They kept getting more and more affordable although the cost were...

    Allstate sued for allegedly tracking drivers’ behavior through third-party apps

    Toyota doesn't seem to have a clean way to de-authorize their sharing data without actually writing to them. Per their website you write to them and they will send you back a letter saying that they will not sell your data. I have an older Yaris (actually made by Mazda) that as far as I can tell...

    mounting bookshelf speakers from the ceiling

    As a rule of thumb, small speakers sound better when they are next to a wall and even better in a corner. The reason that you don't always want to position good speakers next to a wall is because you get a boost at low frequencies. The long wavelengths of low frequencies essentially bounce off...

    A cartoon butt clenching a bar of soap has invaded my online ads

    I subscribe to Ars and have always used an ad blocker since they first became available. Previously when I tried to white list Ars I still got too much crap advertising. It's been some time so I will try again.

    Ars asks: What was the last CD or DVD you burned?

    I had an MRI a few months ago. They said that I could bring in a CD to play while I was in there so I burned a copy of the Chopin Nocturnes to play. All my physical CDs are in boxes in storage so just grabbing one would not be easy. What I found fascinating is the noises that an MRI makes...

    Facial recognition flags Girl Scout mom as security risk at Rockettes show

    I've been to Radio City twice; both in the early seventies. The room is quite wonderful, what is presented there is sometimes as well. The rockettes were quite silly and I think the only reason we went was that we got free tickets. The second event was a "Keyboard Colossus" show at midnight...

    Right-wing doctor group led by anti-vaccine insurrectionist implodes in scandal

    She sounds very smart, a complete over achiever and so self entitled that she is completely pissed that they didn't make her queen after that one in the UK died (never mind that she's american etc.) I find over achievers fascinating; in school I was considered an under achiever because I hate...

    Feds seize $3.36 billion in bitcoin stolen 10 years ago in hack of Silk Road

    The $3.36 billion belonged to James Zhong To nitpick; the bitcoin didn't belong to Zhong as it was stolen property. A more appropriate phrase might be The $3.36 billion was held by James Zhong edit - to > by

    Just say no (to content): Nietzsche’s surprising “information diet”

    I go through different periods of only reading things that truly engage me and my present condition of almost only reading things I really don't care about solely to keep my mind from thinking. While I'm definitely not happy about my current state; I'm genuinely depressed about the what the...

    Facebook loses users for first time ever, market cap drops by $200B

    I just got a recruiter from facebook contact me via linkedin. This had never happened before; probably because I'm mostly an audio engineer/system designer. I politely told the guy that I would never consider having anything to do with meta. They must be getting desperate.

    The room treatment thread

    I find this thread fascinating but I think you are not adequately paying attention to the loudspeakers you are using. I design large sound systems for a living: theaters, churches, train stations etc. One of the things we typically do is try and get as much of the acoustic energy as possible to...

    Focusing sound vibrations precisely can knock over one Lego minifig among many

    "The spatial extent of the focusing depends on the frequencies being used. Higher frequencies [b]typically[b] have smaller wavelengths, enabling Anderson to focus the acoustic energy to a more narrow point in space." Interesting article. I'm perhaps being overly picky but as an audio engineer...
