  • Why It Was Almost Impossible to Make the Blue LED

  • Um... if someone pays you to do a thing, then they own it. Imagine if you paid me a hundred thousand dollars to build a house and then it's my house to live in. Doesn't make any sense at all.

    I'm not defending the company, but the law is pretty clear on this. If you want to own your own work, then start your own company.

  • This chart is pretty shocking, and makes IEA look like idiots. Or maybe it's malice? The IEA's founding purpose was to protect the Oil industry. Supposedly they now also work to "promote clean energy transitions"... but if that's their goal they don't seem to be doing a very good job.

  • Honestly, I think contacts are the best option. The Zeiss lenses move the headset slightly heavier and worse move it further away from your face creating a lever action amplifying the weight issue.

    You can still wear glasses. Just don't put a prescription in them.

    Personally I love my glasses and have never tried contacts, but I think I'll switch to contacts when this product category is more mature.

  • It’s funny too because at the same time AI promises a very different future where screens are less important. Tasks that require computers could be done by voice command or other minimal interfaces

    Apple seems to be the only major tech company that still believes in that future. Microsoft has killed Cortana entirely and all of their AI work is now focused on enhancing ordinary every day computing, Google and Amazon have both been cutting features and laying off staff for their voice assistants. Which means right now, the only serious entrants in that space are Apple and a bunch of startups.

    From what I can see, Vision OS is perfectly suited to it. You can go about your day without any computing, ask your voice assistant a question, see the answer, dismiss it, and move on, without taking devices out of your pocket or sitting down at a desk. What's clearly not ready for that is the hardware - it's too big, too heavy, the battery life isn't good enough, the viewing angle is too narrow, too expensive, etc etc.

    The other thing missing is Apple's voice assistant is clearly falling behind. It has always worked well for simple commands but that doesn't cut it any more. Tim Cook has said they have more to announce on that front "later this year" and it's worth noting that Apple has bought 21 AI companies in the last several years. All they have to show for that is the ability to search for "dog" in your photo library. Clearly they're working on something more meaningful and it seems pretty obvious that a better Siri is going to ship sooner rather than later.

    My best guess is Siri has fallen behind because all of their best staff are working on something to replace it.

    Apple Vision Pro, I think, is two products:

    1. An immersive content viewing experience - movies, photos, games, etc
    2. An experimental new computing platform that developers can potentially use to build great things

    The second won't really pay off until the hardware is better. But the first is good enough justification to ship this product now, even though it's nowhere near achieving it's potential.

  • WhatsApp Chats Will Soon Work With Other Encrypted Messaging Apps

  • This new legislation comes into effect next month. So sure, "not yet", but very soon.

  • WhatsApp Chats Will Soon Work With Other Encrypted Messaging Apps

    跳过

  • Specifically I wanted to know which apps would be able to communicate with WhatsApp

    WhatsApp will allow any service to communicate with their network. But wether or not any do is entirely up to those other apps. I think there's very little chance Signal will ever interoperate with anything for example. iMessage surely won't either.

    Technically it shouldn't be difficult, because almost every chat app these days uses the same protocol (Signal which is an unofficial industry standard and soon to be an official one). The question is how well it fits with their business model. And most companies don't share their business model.

    The other issue is the recipient needs to opt in. You won't be able to send messages to just anyone... and if spam is an issue then everyone might turn it off.

    The bigger question for me is wether or not you will be able to use a third party app to access WhatsApp. As in full access, view all messages, view contacts, create messages, receive push notifications, etc etc. It looks like the DMA might allow a return to software like Adium which is an open source messaging app that used to be able to log into almost any messaging service. These days none of the most popular services are available in the app, so almost nobody uses it.

  • Instead of doing most shit in-house, they contracted out shit tons of parts to the lowest bidder

    No that's not true. What happened is they found things that were not profitable to do in-house and sold those off (they found investors willing to take over their non-profitable production lines).

    ... the investors simply cut costs in order to make it profitable. Which is predictable, what else were they going to do? Obviously an investor expects to make money on their investment.

    Now Boeing is basically stuck - they can't make the parts in house, because they don't have enough staff, and their only supplier sucks, and there is no other supplier.

  • Paris votes to crack down on SUVs | Non-Parisians will be charged almost $20 per hour to park large gas or hybrid vehicles within the city center in a bid to address pedestrian safety and air pollu...

  • I don't know what it's like where you live, but where I live rent in the city works out to about two thirds of my annual income and I have a well paying job (above average for my city).

    So - living in the suburbs is not really a life style choice. I can afford a very comfortable home in the outer suburbs, while in the inner city I could only afford to rent a small bedroom with a shared kitchen/bathroom/living space. And since we have a child, a share house isn't really an option (I did live that way when I was younger).

    And while I love cycling to work I can't do it often, because it takes almost 4 hours (two hours each direction). I can take a bus, but that's even slower (since I have to go to the CBD first, then take another bus across town to the non-CBD area where I work). The bus also costs more than twice as much as driving. Driving, by the way, takes 30 minutes.

    Since I live in the outer suburbs anyway, with nice wide roads, unlimited free parking, I choose to take advantage of it by spending a lot of time outdoors where if you want a cold beer, you need to bring a fridge. If you want a hot meal, you need to bring a full kitchen. If you want to take a canoe out the water, you need to bring a canoe with you, etc etc. So, we have an SUV. And we're not going to give it up. Sorry.

    If my city banned SUVs, I'd probably just start taking taxis instead. I'm not sure that would be better for the environment or local traffic. Definitely wouldn't affect my daily life, since I don't live or work in the CBD.

  • Honestly, they should just ban all SUVs from entering altogether.

    That's not going to convince me to sell my SUV. It'd just cause me to buy a second car.

  • Amazon finds $1B jackpot in its 100 million+ IPv4 address stockpile | The tech giant has cited ballooning costs associated with IPv4 addresses

    跳过

  • From the article, 79 million IPv4 addresses

    So that's how many IPv4 addresses Amazon has? For comparison, if I ask my server provider nicely they will give me a huge block of IPv6 addresses. For free. The largest block they will give a single customer (again, for free) is a /56 block which is 4,722,366,482,869,645,213,696 IP addresses.

    To give you an idea how big that is... if I had ten billion customers, I could allocate several hundred billion unique IP addresses to each customer. And that's just with a section of the IPv6 address space that networks will hand out for free.

  • it’s just never used or enabled in the software by default

    ...and most people who own those devices have never heard of IPv6 and don't know how to enable it. They just won't be able to access your website. If Amazon dropped support for IPv4, there wouldn't be anything i'd be able to do to deal with the fall out. I'm not going to send a technician to every single home of every customer I have. What I could (and would) do is move all my stuff off Amazon.

  • a lot of sys and net admins really don’t like the idea of every lan device being globally addressable

    Those admins don't know what they're talking about. IPv6 has a region of the address space that can only be reached locally - similar to the 192.168.x.x space in IPv4. The only difference is it's really big (way bigger than the entire IPv4 space).

    As for NAT... there's nothing stopping you from using it with IPv6. It's often unnecessary, but if you disagree you can use it. And in practice NAT is often part of the transition process to IPv6 - my cell network carrier for example gives my phone an IPv6 address on their internal network but routes all my traffic to the regular internet via IPv4. They are using NAT to do that. If you try to ping my phone's IPv6 address, it won't reach my phone.

  • IPv6 is here, and has been for a long time. But if, for example, your web or email server can only be reached over IPv6 some people will not be able to load the site or send emails to you.

    The entire internet is configured to work with IPv4. Some of the internet (less than a quarter) is also configured to also work with IPv6.

    Imagine if your home had two driveways on different streets. Do you tell everyone both addresses, or do you pick one of them? Probably just one right? Now imagine if the second address can only be reached if someone has an off road capable vehicle. And you don't know what vehicle someone has - which address would you give them? Is it even worth having two driveways?

    That's the situation we're in. IPv4 support is required and works perfectly. IPv6 is optional and doesn't always work.

  • What? That's not a fire hazard at all. Your second battery would provide at most 100 watts which is perfectly safe and not going to cause any fires.

    If you submerge the battery in water or stab it with a knife... sure it might catch fire. But that's pretty much the only risk so long as you stick to reputable brands that comply with safety standards.

  • I bet it does have power pass through. Lots of people are going to use this all day at a desk and you'd get to a thousand cycles in just three months if plugging it into the wall just charges the battery. It needs to be passthrough.

  • The USB-PD spec can cover a verity of voltage and amperage combinations

    That's not really true - it maxes out at 5 Amps which is only a decent amount of power if you use (relatively) high voltages. Vision Pro runs at 13 volts, which isn't supported by USB and if it was that would only be 65 watts - nowhere near enough to power this product.

    Running at higher voltages (USB can do up to 48 volts) would likely have problems, it might be less efficient for example (which would mean they have to give it a larger battery).

  • the only difference is that the bolster has some notches in it for the BATTERY to lock into

    Um, it has twice as many pins. The same number of pins as thunderbolt which likely isn't a coincidence.
