  • Black Friday is a marketing exercise to get you all riled up about the massive savings you will receive if you buy something RIGHT NOW.

    Suffice to say that the actual bargains on the day are far and few between.

    If you actively track pricing you’ll discover that the price goes up before the event, then drops to the same or slightly lower pricing on the day. The “bargain” is notional at best.

    Then there are the “pre Black Friday” sales, and the “Cyber Monday” ones afterwards. It’s all just marketing.

    If you want an actual bargain, find what you’re looking for, set a price watch on it and track it for as long as you have patience. When you’re ready, buy it from your preferred supplier and get them to price match the amazing price.

    As far as refurbished goes, ask yourself what is the upside for the supplier to give away any bit of return on their spend to refurbish the item in the first place?













  • DRM is one potential reason, but not the only one.

    Content is licensed under specific conditions, resolution, audio tracks, closed captions, etc. Two organisations might have licensed the same title, but not the same conditions.

    You can see this clearly during the Olympics where some channels only have secondary rights, or only certain events, but only free to air, not online, etc.

    Added to that are marketing and exclusively deals and in the end it’s anyone’s guess what you actually end up with.


  • I don’t know, but I doubt that the frequency response of a mobile phone microphone is either linear or consistent across sound level.

    I don’t even think you could compare two sounds with different frequencies, but I don’t know.

    I suspect that calibration of any such thing would require a whole lot of infrastructure, consider for example the angle of the phone in relation to sound and the impact of holding the phone in how it affects vibration and noise damping.

    You might be able to use a calibrated sound level meter and pair it via Bluetooth with your phone, but I think that’s going to be as close as you might get.

    In the past I’ve tried a wired USB microphone, but the OS isn’t real-time, so the jitter was horrendous. A pi would give you a more consistent result.






  • I just pirate media I like

    In other words, your computer is downloading stuff from other computers, that’s potentially receiving stolen property, but a potential argument might be that you didn’t know that it was stolen. It’s not a good argument, but it’s an argument. So you’re an individual who potentially broke the law. Depending on how much money you have, you might get a knock on your door.

    But then, you also distribute that potentially stolen property to other computers, because that’s how BitTorrent works, and now you’re part of a distribution network dealing with stolen property. The chances that once you’ve discovered you come away with just a slap on the wrist are slim to none.

    How do they find you?

    Through your IP address.

    How?

    By figuring out who owns that address, who loaned it to you to get online at that specific time. One packet at a time the research will bring them closer to knocking on your door.

    So, is it a big deal that your public IP address is linked to torrenting? Yes it is.

    Is this the whole story? Not by a long shot, but it’s not my job to teach you how to break the law.
