- Comment on In Cringe Video, OpenAI CTO Says She Doesn’t Know Where Sora’s Training Data Came From 8 months ago:
Don’t downvote this guy. He’s mostly right. Creative works have copyright protections from the moment they are created. The relevant question is indeed if they have the relevant permissions for their use, not wether it had protections in the first place.
Maybe some surveillance camera footage is not sufficiently creative to get protections, but that’s hardly going to be good for machine reinforcement learning.
- Comment on 8 months ago:
Yes, but a heat pump for heating is somwhere from 200% to 500% efficient.

the original 1s and 0s
I think your issue starts there, you already have to decide how to build your sensor:
- If it’s a CMOS sensor how strong do the MOSFETs amplify? That should affect brightness and probably noise.
- How quickly do you vertically shift the data rows? The slower the stronger the rolling shutter effect will be.
- What are the thresholds in your ADC? Affects the brightness curve.
- How do you layout the color filter grid? Will you put in twice as many green sensors compared to blue or red as usual? This should affect the color balance.
- How many pixels will you use in the first place? If there is many each will be more noisy, but spacial resolution should be better.
All of these choices will lead to different original 1s and 0s, even before any post-processing.
- Comment on The three million toothbrush botnet story isn’t true. 9 months ago:
I mean we haven’t seen any proof, but Stefan Züger of Fortinet told that story as a supposedly true event to Journalists of CH-Media. The very article Kevin Beaumont posts says that the scenario is a real event.
- Comment on RIPE, Regional Internet Registry, hacked because an admin account's password was ripeadmin 10 months ago:
Of the two RIPE actually existed first. RIPE isn’t just a forum, it is the community of European and Middle Eastern IP network operators. It started as coordination meetings of some European operators and grew from there. At some point the RIPE community was large enough that they founded the RIPE Network Coordination Center with full time employees as a sort of secretary role for the community. Later when the RIRs were created to decentralize the management of IP resources that job was assigned to the RIPE NCC for the RIPE region.
My work place is one of those original European operators and the colleage who represented us at ripe-1 is also still employed, though close to retirement now :-)
- Comment on How many of you actually use the headphone jack on your phone? 11 months ago:
When I get a call at home while already wearing my wired headset I like to just plug it into the phone.
Since my current phone was bought used I had to compromise on some things, so I don’t have a headphone jack anymore. I use a USB-C Adapter now. I use it for most phone calls, especially the longer ones with family. So probably for a few hours per month.
For quite a long time, until about 2021, I was still using wired headphones when on the go, but nowadays I’m addicted to noise cancelling, so that use case has moved to Bluetooth now. My protective headsets from work (both the over-ear and the in-ear set) also use Bluetooth.

The way you use “PC” as a synonym for “Windows” proves that you are indeed a long term Mac user.

87% of teenagers use Apple
Do you mean US American teenagers, or North American teenagers, or who exactly? Surely that can’t be global?
- Comment on Japanese Institute breaks optical fiber speed record with 22.9 petabits per second — 1,000 times faster than existing cables 11 months ago:
For perspective, at work for our production network through Switzerland, we use at most 16 QAM with dual-polarization, and at most 88 channels. With just normal single mode one-core fibers. This paper has just everything blown up in all directions of cool.
- Comment on Japanese Institute breaks optical fiber speed record with 22.9 petabits per second — 1,000 times faster than existing cables 11 months ago:
Yes, to get their speeds they used the usual wavelength division multiplexing, except over an insane 750 wavelength channels, space division multiplexing over the 38 corse with 3 modes, and 256 QAM with dual-polarization in each
- Comment on Japanese Institute breaks optical fiber speed record with 22.9 petabits per second — 1,000 times faster than existing cables 11 months ago:
I think that both fibers with air and those with vacuum exist, but it’s a bit far from my operational reality, so I’m not that sure. I just read in industry news that euNetworks has deployed 45 km of Lumenisity hollowcore fiber and that Microsoft bought Lumensity
- Comment on Japanese Institute breaks optical fiber speed record with 22.9 petabits per second — 1,000 times faster than existing cables 11 months ago:
The financial types are generally more interested in hollow core fiber, to get their latencies even further down for high frequency trading. Because light travels at almost c in hollow core but only at 2/3 c in fiber core.
- Comment on Japanese Institute breaks optical fiber speed record with 22.9 petabits per second — 1,000 times faster than existing cables 11 months ago:
That depends on where those bytes go, though. There is also the concept of “settlement-free peering” and content caches that are located in the ISP network.
For example we have a Google Global Cache instance in our network, so most Google traffic is served from there and we don’t pay anyone per byte, we only pay for the power and space. Same for Akamai. Then for Microsoft, Cloudflare and Facebook we have peering links, where we can send and receive data related to their services freely, without balance requirements.
Of course this is only possible for larger networks (peering with everyone is not feasible) and we still pay for the other traffic, but it takes care of a lot of the Volume.

Thank you!
- Comment on Japanese Institute breaks optical fiber speed record with 22.9 petabits per second — 1,000 times faster than existing cables 11 months ago:
Actually it’s about 2/3 c, the refractive index is around 1.47
- Comment on Japanese Institute breaks optical fiber speed record with 22.9 petabits per second — 1,000 times faster than existing cables 11 months ago:
The breakthrough isn’t things moving faster but more fibers per cable.
No, it’s actually more cores per fiber, and using those very well for space division multiplexing on top of the normal wavelength division multiplexing. They are talking about 22.9 Pb/s per fiber, not cable, the Tom’s Hardware article is just wrong.
Cables can already contain hundreds of fibers, for example 576 here or into the thousands if you use stacks of ribbon cables in the subunits, for example 3456 here

- Comment on Great! I like getting tracked by 766 third parties! thanks Outlook 11 months ago:
Good as always for me. The only issue is syncing contacts and calenders with MS-Exchange Servers, for that you need plugins and I haven’t really found a good combination, but I don’t know if my workplace is at fault too.
- Comment on Paris mayor quits X platform, calling it a ‘gigantic global sewer’ 11 months ago:
Isn’t she the one with the big sewer improvement project to stop flooding the Seine with poop water whenever it storms? She must be basically an expert on sewers among politicians by now, so I’ll trust that assessment.

- Comment on 8GB RAM on M3 MacBook Pro 'Analogous to 16GB' on PCs, Claims Apple 1 year ago:
A good first step would be: don’t make your own proprietary graphics API (Metal) and support Khronos standards (OpenGL, Vulkan) instead.

- Comment on Mozilla tells extension developers to get ready to finally go mobile 1 year ago:
It’s weird, this is presented as new, but I had adblock on Firefox on Android from the start.
That and flash support were two of the major reasons for using Firefox on Android in the first place. This was back around 2010, when most porn sites still used flash players for video. Then flash died, that was fine. Then at some point Mozilla reduced the available extensions a lot, but at least some adblocker was still available.
- Comment on Mint is shutting down, and it’s pushing users toward Credit Karma 1 year ago:
Everyone but you got it, I don’t think the issue is with the joke.
- Comment on Mint is shutting down, and it’s pushing users toward Credit Karma 1 year ago:
I thought I made it really obvious, but I guess I’ll spell it out explicitly: The guy was making a joke, telling you to diversify into covering other things also called mint, like the finance app this comment section is concerned with.
- Comment on Mint is shutting down, and it’s pushing users toward Credit Karma 1 year ago:
Yeah, you could open with a feature on Mint perhaps, you know before it goes away at the end of this year.
- Comment on Heat pumps can't take the cold? Nordics debunk the myth 1 year ago:
I just don’t buy this twice as efficient bullshit.
Do you understand how heat pumps work? The heat you’re drawing on is the the heat of the out5side compartment on the outside, therefore the heat moved to the inside can be more than just the heat equivalent of the electric energy you put in. That’s how these achieve more than 100% efficiency, in general.
Now the trick to moving heat from a cold outside compartment to a warmer inside compartment lies in the compression. If you draw even a moderate amount of heat energy into your medium, then compress it, it will turn quite hot allowing you to dump heat into your warm inside compartment. Then as the medium flows out you let it expand and it turns really cold, cold enough that it can draw in heat from the cold outside.
- Comment on Google Fiber goes big with 20-gig plan 1 year ago:
Flexoptix reprogrammable tranceivers are a godsend for that. We use them almost exclusively at work and so do quite a few of ours customers (Universities and other places of higher educaton). But it’s probably hard to justify the cost of a reprogrammer box for a household. You can buy their transceivers pre-programmed though.
