- Comment on Trump places 25% tariff on imported autos, expecting to raise $100 billion in tax revenues 2 days ago:
Lol no it won’t but it’s sure going we hurry average people.
There is no way tariffs will ever match or cover income taxes.
And tariffs always and only benefit the rich.
- Comment on Why hasn't video quality improved much over the past ten years? 1 week ago:
Ok, since were (as a group not you specifically) are getting pedantic, I should clarify that any recording of video is inherently compressed. There is no way to capture 100% of an image ever. There is optical compression created by the lenses, then their is encoding compression created by the Analog to Digital conversion, or if capturing in analog there is physical medium compression. Film has grain size and quality which limits it resolution, analog tape is limited by the speed, width, and magnetic medium density.
So for the sake of this larger discussion Uncompressed should probably refer to the point at which the content is being captured to a medium regardless of what that medium is.
Now in the context of broadcast and professional video production Uncompressed means specifically that the transport and capture of the content is dont done with the removal of any part of the data. Now even that is a little misleading because the sensors on most professional cameras can capture higher data rates than 12G, but the transport specification only allows for 12G we have to use chroma sub-sampling to go from 444 to 422 when we put the content onto the wire.
So all that said, when I talk about Uncompressed UHD video requiring 12G I mean that no codec is applied, and no frames are dropped. We are running at the maximum specified bandwidth of our link which is 12G UHD video at 59.94 frames per second. Every pixel is written every frame regardless of if its a camera pointed at a wall watching paint dry or not.
So, last thing on Lossless compression, as a professional I frequently take issue with codecs that claim lossless quality because frequently I can see the difference between the vast majority of compressed formats vs uncompressed formats. Sometimes instantly, sometimes it takes a few min before I see the compression. Lossless compression generally is one of theos 9 out of 10 doctors things were the majority of people say they cant see a difference therefor they can claim its “lossless.” I can frequently see the difference between 444 and 422 chroma subsampling, and that is not even considered compression. I am one of the annoying people who walks into a bar and asks why all the HD tvs are set to “fill” on an SD channel.

When its dry, brush and shop vac. If that’s not enough, then damp tarry cloth and two buckets, one with clean water, and one to rinse in, never will the two meet.
- Comment on How much of a risk is it for naturalized US Citizens (or those with Derivative Citizenship) to protest against the US government, compared to natural-born US Citizens? 1 week ago:
Legally none, but given that were no longer governed by law, no idea. I would say talk to a civil rights lawyer if you are a Naturalized citizen and want to participate in your first amendment rites.

The standard is defined as 12000Mbits/s and spelled out as 12G-SDI or 12G SMPTE 2110.
So i do tend to mix things up since big G and little G mean different things in computer land.

Over the air to an HD tuner looks like dog shit? What channel and location i can investigate.
If it’s a local station over cable then it’s because it’s compressed and at best 720p.
- Comment on Why hasn't video quality improved much over the past ten years? 1 week ago:
Most news is real-time transmission and over the air TV is still running very high bandwidth. It’s you plug in an HD antenna or ATC.3.0 antenna it will blow away the video quality is Netflix Amazon or YouTube.
- Comment on Why hasn't video quality improved much over the past ten years? 1 week ago:
Like livestreams? That being the exception but most ‘content’ isn’t live.
A shocking amount of content is live, and then encoded for streaming. Given that you are on Lemmy I would guess that your interests dont overlap much with content that requires live transmission. So this is an expected selection bias, not being critical, and totally not judging, just pointing it out so you can be aware. I bet your parents still have cable.
- Comment on Why hasn't video quality improved much over the past ten years? 1 week ago:
Not all content can be downloaded, and for many people they want to watch what they want to watch right now, and waiting for the download is not something they are interested in.
Also rights holders dont want you to have an offline copy if they can avoid it, that way its easier to monetize for them.
- Comment on Why hasn't video quality improved much over the past ten years? 1 week ago:
Compression. While Compression tech HAS improved, its been maintaining our current quality while reducing bandwidth needs.
A 1080p Bluray disk will look far far better than Netflix in 4k every time because its not compressed. The reality is that any form of compression will cause loss in fidelity in some way, so the only way to really improve video is to increase the bandwidth of the video.
I talk to IT nerds frequently who are asking things like “why do you need 16x 400GB ports of non blocking bandwidth” to which I have to explain that a SINGLE stream of uncompressed UHD is 12GB/s and we are trying to put 200+ streams onto their network.

- Comment on How would we choose a "world language" in a fair way, for a hypothetical one world government? 2 weeks ago:
Only because we’re lazy in the US and still have all the money. Watch as our economy falls and how quickly people will transaction to Chinese, French, German…
Without business English will start to decline. It’s a shit language and we’re kinda asshole to the world about it.
- Comment on How would we choose a "world language" in a fair way, for a hypothetical one world government? 2 weeks ago:
I think we shouldn’t.
Diversity and language are strengths. We already have enough common languages for diplomacy and business.

The rich when tax cuts go into effect. It’s always been a mass transfer of wealth and the plan from the beginning. It’s why we always knew any bargaining was bull.
- Comment on Do you find this compelling evidence to doubt the result of the election? 4 weeks ago:
Are there any sources for this, or are we just supposed to take a random AM radio station and random website that lists its executive board without real names, links to other verifiable profiles, or any way of proving its legitimacy?

- Comment on DOGE needs to 'cut deeper' and must ‘keep slashing’ to succeed, says Kevin O’Leary 5 weeks ago:
I am not tying it directly to Trump, but the stated goal has been to disrupt every federal system, service, and person and the FAA was probably the closest to breaking before the regime change, so it sure seems like it could be collateral damage.

Older printers often require more maintenance and old software. If people struggle to set the clock on their microwave how do you expect then to plug in and use an old printer with Windows XP drivers.

Deep State was always projection at best. Real Deep State is the oligarchy, and Musk now has his control.

- Comment on Are we going through another scalping apocalypse? 1 month ago:
Unlike Nvidia they will not be artificially restricting production. It’s already in backrooms and shelves they’ve been bringing them over from manufacturers for months now. There will probably still be some scalping but it’s expected to be enough supply to actually meet demand.
- Comment on Are we going through another scalping apocalypse? 1 month ago:
No nvidia’s just greedy AF. The AMD card due out in March is expected to demolish the 5070 and nearly match the 5080 at $500.

- Comment on Why are headhunters or recruiters so laser focused on getting my resume? 1 month ago:
often yes, they need to bring a number of candidates to the company that they are working for to get paid. So having your resume lets them stuff open jobs with “valid” candidates.
