Well done.
- Comment on This new 40TB hard drive from Seagate is just the beginning—50TB is coming fast! 7 hours ago:
I just addressed that in a post above yours.
Basically smaller form factors are probably just better in this case. 3.5" drive bays were designed with more complicated mechanical drives in mind, and given how nand flash memory works, they don’t make as much sense for SSDs.
- Comment on This new 40TB hard drive from Seagate is just the beginning—50TB is coming fast! 7 hours ago:
Well, that’s certainly possible, but 2.5" might just be a better form factor for SSDs. The thing is, an SSD is just a bunch of chips on a PCB, so they really don’t need the extra height afforded to them by a 3.5" bay.
You could probably fit 2 pcbs one on top of the other within a 3.5" drive, but that would also be more complicated to manufacture and worse for cooling than using two individual 3.5" or m.2 cards.
Also, for a bunch of reasons smaller is usually better. Generally, it tends to be cheaper to use a few large capacity chips on a small board than it is to use a lot of lower capacity chips on a larger board. Of course fewer parts also means fewer potential points of failure, so better for quality control. And again, smaller cards are better for case airflow and cooling.

Yeah, in my last IT job I tried to get my manager to run the big purchases by me first. Eventually he started to see why.
(He was a good manager, just not a huge hardware nerd)

When I say “compress” I mean downscale. I’m suggesting they could have dozens of copies of each texture and model in a host of different resolutions.
Yeah, that’s generally the best way to do it for optimal performance. Games sometimes have an adjustable option to control this in game, LoD (level of detail).
- Comment on Britain’s Companies Are Being Hacked 2 days ago:
That is definitely a concern! But as the company’s entire future depends on their digital security policies and practices, I expect them to take it pretty seriously. There
couldwill certainly be shitty companies, but hopefully they won’t last long and the reliable companies will survive. - Comment on Ironically, people making fun of the "Gnu/Linux" copypasta is probably one of the main ways people know what Gnu is 2 days ago:
Was Alpine built specifically to be able to tune out Richard Stallman?

No.

Much to the chagrin of Richard Stallman who feels he isn’t getting credit for his work. This is his punishment for being the absolute worst at naming things.
Hear hear! And let’s hope he learned his lesson!

This is why it really should have been called “NNU”, that would work perfectly.

My only gripe with GNU is the acronym itself.
Sure, the joke is clever, a recursive acronym “GNU is Not Unix”, cute. But they could have used absolutely any letter as the first letter and that joke would still work. So why didn’t they choose something pronounceable? I mean, the option was right there. ENU, ANU, INU, ONU, SNU, those would all work. Hell, even NNU would work, you could pronounce it “the new project”.
- Comment on The Engine of our dreams exists. It's Clean, Powerful, Supercharged and 2 Stroke 3 days ago:
People will go to some great lengths for a little extra performance. Think of the Wankel engine, this is basically the same sort of power/weight improvement but it’s immensely less complicated and more practical with this 2 stroke engine. But that Wankel today engine has actually gone into mass production in a few cases, notably in the much loved Mazda RX-7.
And let me be clear, this 2 stroke is far more practical than the rotary Wankel engine.
- Comment on The Engine of our dreams exists. It's Clean, Powerful, Supercharged and 2 Stroke 3 days ago:
I thought the video was pretty convincing, this engine seems pretty badass.
Honestly, this engine could be a pretty big deal for a few industries, small aircraft especially. Switching to these two stroke engines could improve the power/weight ratio of your engine by nearly 2x and not lose any fuel efficiency in the process, for small aircraft that’s a really big deal.
For a specific example, a Cessna 172 carries about 300 lb of fuel, and we know that the plane’s performance improves significantly when it’s tank is nearly empty, the top speed for example is about 15% higher on a nearly empty tank. Its standard 4 stroke engine weighs about 250 lb, so a 125 lb weight reduction would mean a proportional improvement, but not just to top speed, but also shorter takeoff distance, faster climb, higher max takeoff weight, etc.
- Comment on Britain’s Companies Are Being Hacked 3 days ago:
I’ve said it before, there’s really only one way to make user data safe. Nations that want their citizens’ data to be safe need to pass laws that make exposing that user data extremely (cripplingly) bad for companies.
The penalties need to be so harsh that the fines could put them out of business. Companies should not want to hold user data, they need to think of user data like toxic waste, more of a liability than a valuable resource. When companies need user information to operate they can utilize “data handler” companies, firms that specialize in secure storage and are willing to risk actually holding user information. These companies can provide APIs for other organizations to actually access the user data when needed. But to be clear, most companies will not want to store that data on site, because the risk of exposure could be ruinous to the company.
There’s an extra benefit of this plan too. Most organizations don’t hold user data, they pay someone better at it to hold it for them. Because they need to pay for API access, they’ll use the data sparingly, not frivolously throwing user data everything, tracking users on the web, or sharing data with advertisers. Having to pay for access will make companies use our data less.

The exactly.
You want something from me, fine. But nothing is free and you may not like my price, and in that case you’re simply out of luck.

I’ll switch to jellyfin as soon as it works nearly as well.
But for the moment it’s missing a lot of features compared to Plex.

Christ, not exactly a model of power efficiency is it?
Also, if it’s drawing that much power, how could it possibly dissipate all the heat? It must sound like an F-16.
I expect this card will be a hard pass from me…
- Comment on AI could already be conscious. Are we ready for it? 1 week ago:
I don’t think anyone needs to worry about “missing it” when AI becomes conscious. Given the rate of acceleration of computer technology, we’ll have just a few years between the first general intelligence AI, something that equals in intelligence to a human and a superintelligence many times “smarter” than any human in history.
But how far away are we from that point? I couldn’t guess. 2 years? 200 years?

Well, currently it’s available on the dashboard. So no, no quite. But eventually, yeah it’s pretty easy to predict it’s heading the way you were thinking, just give it time.

Yeah, imagine a network backup system that could actually back up your 20 TB media center in a few hours rather than a few days.
- Comment on Trump says a 25% tariff "must be paid by Apple" on iPhones not made in the US, says he told Tim Cook long ago that iPhones sold in the US must be made in the US 1 week ago:
It’s pretty clear what he wants. He wants WW3.
-
He wants to consolidate manufacturing to make the US more self sufficient. The tariffs are simply a tool to designed to encourage local manufacturing.
-
He wants to start dominating smaller countries just like Russia and China. As well as annexing neighbors. He wants to do what Hitler couldn’t. He wants to use the most powerful military in the world.
If he wants to go to war, then he’s probably going about things the right way. Historically, being reliant on other countries for your supply chain can be a huge liability in war. For example, we were in danger of losing WW2 because of a lack of access to rubber. We need it for boots and tires, and we got it all from South East Asia, our access to rubber was completely cut off by Japan, it was a huge problem until we developed synthetic (plastic) rubber. We literally wouldn’t have been able to put boots on the ground or vehicles on the road.
If we were to end up in a conflict with China for instance, we would lose access to a lot of high tech manufacturing, we suddenly wouldn’t be able to make new computers. That could be bad.
Anyway, the signs are all here, Hitler V2 wants to mobilize soon.

I wish I could argue with this.
- Comment on Mozilla is shutting down Pocket, their read-it-later and content discovery app, and Fakespot, their browser extension that analyzes the authenticity of online product reviews. 1 week ago:
I never understood its usecase.
I used to use it when I was browsing the web at work. If I was reading something at the end of the day, or if it was something I didn’t want to read at work, I’d give it a pocket bookmark. Then I could pull out my phone and finish right where I left off during my train commute.
- Comment on It's Breathtaking How Fast AI Is Screwing Up the Education System 1 week ago:
I just think banning them outright is bad for needing to contact parents, especially for kids like me who had after school activities often.
Ok, well that’s completely ridiculous.
Look, 25 years ago nobody had cell phones in school. Kids had just as many after school activities, this wasn’t a problem. It was sometimes inconvenient, but not a problem. It’s also worth remembering, many rooms in every high school have phones, you’ll be able to use one if you need to.
I get wanting to have your phone throughout the day, I do. But on the other hand… no.
- Comment on It's Breathtaking How Fast AI Is Screwing Up the Education System 1 week ago:
but people here in Lemmy (same on Reddit years ago) completely lose their shit with that idea
I’ve never seen anyone over 19 who was opposed to this idea. It’s obviously the right move. Phones don’t belong in school.
