  • Audio cable measurements are driving me crazy — why can’t I get them to null?!?

    Jump

  • (speaker calbles almost warrant a debate due to the currents and the reactive load, but the smartest people I knew in the field would just use domestic mains cable for this as it ticked all the boxes that mattered at a low price. They'd literally connect £10k speakers.up with it!)

  • Audio cable measurements are driving me crazy — why can’t I get them to null?!?

    Jump

  • I suspect you haven't missed anything and the audio tracks provided have been either inadvertently or deliberately manipulated by some other factor unrelated to the RCA cables.

    For context, I'm an Elecronics Engineer with a Masters Degree and 17 years industry experience in a mix of RF and Pro Audio product design, including designing high spec audio converters for both studio and test and measurement use.

    Apart from something extraordinarily badly designed, broken or dirty, there is no plausible reason why a cable carrying a signal with no significant current and no high frequency components can have any effect on that signal - high frequency audio is approximately DC in the wider scope of Electronics Engineering.

    That answer doesn't suite people trying to get rich selling ridiculous cables though.

  • How come residential power lines aren't buried underground still?

  • Well yeah, it's quite easy to keep your energy prices low when you

    • have a wealth of hydrocarbon sources in-country
    • supplement them by bombing other nations until they give you there's
    • don't give a flying fuch about the planet

  • Population of Sweden: 10.6 million

    Population of the USA: 340.1 million

    So the population density is very similar and I therefore don't understand what you're getting at.

  • Ripping Blu-Rays

    Jump

  • I started trying to do this a while back and hit a bit of a brick wall... Key takeaways:

    • You can just rip the video as-is, retaining quality, but at the expense of file size - BluRay uses quite light compression so you're looking at potentially 40GB per 1080p film.
    • So then you think "okay, I'll re-encode it using a modern algorithm, maybe x265 or AV1"... Massive rabit hole! To get a good quality re-encode you need to have a lot of time on your hands. You can do it quickly (e.g. an hour) using a GPU but the results will be terrible. Good results take not just many hours to encode on a high end consumer CPU, but also often several iterations of this to get right. Some things (animation, new digital films) are manageable with some default settings, but anything that was originally filmed on real film and has noise is extremely difficult to get right.

    In the end I reverted to finding a copy someone else had encoded if possible, or for rarer stuff I now just have a fat wallet full of the original disks.

  • ‘F**k you’: Trump drops F-bomb before flipping off autoworker

  • Is a peacoat a coat soaked in pee?

  • The singular they is actually such a natural part of the English language, the people complaining about it almost certainly use it without noticing

    Jump

  • The thing that really grinds my gears is the excessive use of "he/she". Workplace training is a regular offender for this. Just use the word "they" FFS, it's sat right there on the shelf for you.

    Or don't, just go with "he" or "she", this fictional person in your 'case study' isn't real, they don't give a shit.

  • Changed my life

    Jump

  • We have them in kitchens that need to serve a large number of people - big offices, big hotel breakfast areas, transport lounges, etc.

    But a standard kitchen, I think it's like someone else said in this thread: The time it takes to boil a 240V kettle isn't much more than the time it takes to get the mug ready, so there's no real benefit to going through the extra structural work to fit a boiling water tap.

    Also I think most "boiling water" taps are actually like 95°C, not boiling, so if you're a black tea snob that isn't acceptable.

    Trump’s Assets SEIZED

  • WTF is this slop... "Just minutes ago [...] Former U.S. President [...]" ???

  • Trying to activate a new BT account

    Jump

  • I was very tempted, but the cost of their uncapped service was just a bit too much. You get what you pay for I guess, but I'll take the occasional mild infuriation over around £35pm extra cost.

  • More of a famous quote I guess, but:

    "Never attribute to malice that which is adequately explained by stupidity."

    Since I first heard it, I've been far less annoyed / paranoid about other peoples actions, at work in particular.

  • If the US gets a new president in 2029, I'll be devastated if they don't take the opportunity to do a major speach or something against the backdrop of a half derelict East Wing - it would be iconic.

  • Not my experience. I've had my X1C for a year now and have not had to 'dial in' a single thing.

    Most of my prints are functional items in PETG of various colous. Some PLA for cosmetic parts. And I did some things in TPU earlier in the year. Probably been through like 10kg of filament on it.

    Can't think of a single serios print failure that wasn't human error - e.g. forgot to clean the bed, didn't support it properly.

    My one gripe is that when changing PETG reels, it doesn't always manage to wipe the nozzle very well leaving a few rogue stringy bits that usually just pull off.

    And obviously I don't love the closed-wall software situation, but their software is pretty good.

  • What technologies were ubiquitous ten years ago and are much less common now?

    • In 2015, UK consumers spent approximately £1.5 billion on physical entertainment media, including DVDs, Blu-rays, and CDs.
    • By 2025, that figure has plummeted to under £400 million, with DVDs and Blu-rays now representing less than 10% of total video spend.
    • In 2015, streaming was growing but still secondary. Netflix had around 5 million UK subscribers, and Spotify Premium was under 2 million.
    • By 2025, streaming dominates:
      • Over 90% of UK households subscribe to at least one video streaming service
      • Netflix, Amazon Prime, Disney+, and Apple TV+ collectively exceed 40 million UK subscriptions
      • Music streaming accounts for over 85% of music revenue, with Spotify, Apple Music, and YouTube Music leading

    Have you ever traveled outside of America? (Not to Canada or Mexico)

  • Caveat: I don't know you or your manager, so your experience may be very different.

    But as someone who has ended up in management in three previous roles (not currently) your post brought two thoughts to my mind:

    1. For me, I'd far rather people in my team came to me and were open about things. Don't bottle it up and hope that they'll somehow guess - they won't. They're not psychic and they've probably got 101 other things to worry about. Think of it like this: Could you do your job if nobody was ever honest with you about you previous days performance.
    2. If you're tempted to default to thinking of line manager's as the enemy, consider that in most cases they are just trying to do their best while shouldering 10x the shit from their manager than is making it through to you.

    Not saying there aren't bad and/or narcissistic managers about, but I suspect most of the time they only appear that way due to the screws in their back from above.
