Rather interesting design. Notice how the backplate allows air to pass through.

XFX used a shorter-than-normal PCB and a cooler assembly that extends well beyond the PCB.

I don't like the position of the PCIe power connectors, though.

tomshardware.com/news/hdmi-2.1-spec-refresh-rates,36008.html

Hmm... yet another HDMI spec.

48 Gbps bandwidth. DisplayPort tops out at 25.92 Gbps.

Well... why isn't there more 10GbE gear if USB (20 Gbps as of USB 3.2), HDMI, and DisplayPort can operate at data rates far in excess of 10 Gbps?

Networking ought to follow suit. At least Aquantia's trying to bring multi-gigabit Ethernet to consumers...

Also, and I think I've said this before... how in Oblivion are they doing these sorts of data rates on copper?

This time, there's no getting away with UTP cables. 48 Gbps just isn't going to happen without STP.

Michael Frank

@bwDraco What about Terrabit over copper?!

theregister.co.uk/2017/05/10/…

bwDraco

It's starting to feel like DisplayPort is lagging behind HDMI...

(I've been very late to the DisplayPort game and have grown used to DVI and HDMI for display connectivity – most cheaper monitors these days use HDMI while better displays support DisplayPort, if I'm not mistaken – the Dell S2417DG is the first monitor I've worked with that uses DisplayPort natively)

There are already HDMI cables validated for 48 Gbps operation, and they aren't absurdly expensive: prnewswire.com/news-releases/…

Bob

@bwDraco When's the last time you saw a 50m long HDMI cable?

bwDraco

Heh. Good point.

HDMI generally isn't used beyond 3m.

Hmm. So it looks like UTP is probably still okay for shorter cables, but 48 Gbps is really pushing it.

Journeyman Geek

00:42

@bwDraco different uses.

You're rarely going to go long distance on a PC monitor. Its common on PCs.

and cheaper monitors probably use HDMI cause they're really TVs

bwDraco

I suspect the DisplayPort cable that came with my monitor is F/UTP.

I can't quite tell from the cable markings, though.

At least we're not dealing with the insanely thick VGA and DVI cable harnesses of yore...

Journeyman Geek

00:56

hah

crap VGA is thinner than good DP

Oldschool VGA was pretty thick but a lot of contemporary cables are actually pretty skinty

The argument is that net neutrality is bad for business because it limits telco business models, and we need big business for a strong America. America First!

Journeyman Geek

but the core issue here is over a long period of time, ISPs have consolidated

and would rather squeeze as much out of their investment, than invest more, cause why bother?

Its easy to blame the current government, but festering wounds take time and neglect

bwDraco

You see, supporting big business is one of Trump's core political objectives.

Journeyman Geek

01:06

But the network neutrality fight has been going on for years

Trump has, at best, his current term and the next (I kinda hope not, but its not my vote)

What then?

Tried replacing the CPU on Father's old Dell (Athlon 64 x2 5000+, 2.6 GHz K8) with the CPU in the eMachines system (Athlon II X2 270, 3.4 GHz K10)... it's a no-go. System gives a constant amber power light.

Tried doing this before on a prebuilt system?

(Socket AM2 was unusually permissive in compatibility, accepting AM2+ and AM3 processors, but whether the processor will actually work tended to be very dependent on the OEM)

Talk About IT!: Set default printer (without creating a printer) with Group Policy

posted on November 29, 2017 by Luke B

I got disappointed after searching high and low on Google for how to use Group Policy in order to set a default printer. Almost every article I read assumed the reader had a print server available, or would deploy a local printer connection right from the Group Policy Management Console. Finally, I found the solution!… Read more » The post Set default printer (without creating a printer) …

Quick question, that surely must be on the main site, but i can't find it: In powershell, is there any easy way to use a variable in specifying the executable to run? e.g.: $(env:PYTHON)\python.exe -c "...".

So... I got a little extra money for the end of the year.

And there are two smartphones down from BRL 700 to BRL 500

So which one do I buy, Samsung Galaxy On7 or LG K10 K430 TV?

My requirements are:

1) Removable battery (both have it)

2) Decent price (both are OK)

3) Have an official (or decent working) LineageOS ROM

Canadian Luke

I like the size of the Galaxy 7, but I haven't had extensive use of it. I never heard of the LG model. Can't say much more

That Brazilian Guy

Not Galaxy 7. Galaxy On7

> LG is not a very benevolent manufacturer with the independent developer community. Unlike Sony, Lenovo / Motorola and Samsung, they make it difficult for unlocking their boot loader.

Fortunately, this type of restriction was never definitive for the effort of some of the brand's fans. And now, the LG K10, released in 2016, had its bootloader unlocked successfully. It may not be a smartphone. It may seem like something small, but it's certainly the first step to starting new tests.

A novelty encourages the developers around a device that, curiously, has its followers even without having…

"It may not be a smartphone" -> Google translate produced this phrase out of thin air. It's not on the original text.

Is... Is it Google trying to say something to me here?

"Don't buy it! It may not be a smartphone!"

OMG, what is it then? Is it... Is it a bomb?!

Is it a strudel?

Canadian Luke

Nah, Samsung has bombs covered

I never heard of the On7, so i can't give much advice... Although I really like my Asus phone

That Brazilian Guy

19:20

Sigh. I have until night to choose it, the price might change tomorrow. =/

Apparently neither have official Lineage ROMs. There are ROMs for the K10, but not this specific TV-powered model for the Brazilian market.

Why those goddamn Brazilians love their TV so much?! Damn you Brazilians!

Canadian Luke

Lol. I am disappointed that I can't find any custom ROMs with adequate abilities for my Asus phone, but the stock ROM does 99% of what I want

My big issue is not having root immediately (dumb me!), so I can't change the hostname, or view saved wi-fi passwords

That Brazilian Guy

Sigh. I really wanted one I could have root and install a custom ROM.

That Brazilian Guy

19:58

So, K10TV has better specs (octa-core, IPS screen, 8 MP camera, 1080p video, android 6.0)

While On7 has 1,5GB RAM instead of 1GB, support for 128 GB storage instead of 32 GB, and 3000 mAh battery instaead of 2300 mAh

And the On7 has unnoficial rooting and Lineage. There are tutorials on XDA and stuff.

Which is a big factor for me. Although it's supposed to void your warranty if you root it.

Which is an utter, total, complete bullshit IMO

I'm more inclined to buy the On7. But it uses that TouchWiz UX instead of a more pure experience.

Not sure if it's a bloated / slow UI or not

bwDraco

20:24

Well, my OnePlus 3T has been running LineageOS since day one.

A perk of having root is being able to keep the battery in good condition for longer thanks to access to low-level charging controls.

And I can't decide if I want to root it and install an unofficial Lineage 14.1 ROM

(which, in practice, could mean giving up on the warranty or getting a big headache should I need it)

or if I want to wait one year for the warranty to expire

80 Plus

80 Plus (trademarked 80 PLUS) is a voluntary certification program intended to promote efficient energy use in computer power supply units (PSUs). Launched in 2004 by Ecos Consulting, it certifies products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load. Such PSUs waste 20% or less electric energy as heat at the specified load levels, reducing electricity use and bills compared to less efficient PSUs. == History == Ecos Consulting (promoter and owner of the brand) and EPRI (Electric Power Research Institute) develop...

....and?

Ramhound

I am reading this information correctly in that, a 700 Watt Gold at 100% would only be 609 Watts?

That Brazilian Guy

I'm not sure, but every device ever has a loss to heat and etc and you won't ever find a 100% efficient machine.

Ramhound

21:55

I do know that a 700 Watt PSU isn't going to do 700 Watts at 100% efficiency. This certification program is clear as dirt.

You just have to check if this seal means it's more or less efficient than the average (yeah I am too busy / lazy to read the wiki article)

Bob

morn

@Ramhound No.

A PSU is rated for its output power.

A PSU rated at 700W should be able to provide 700W out.

If it were only 80% efficient at 700W out, then the input poewr required to provide 700W out would be 875W in.

In practice, efficiency is a curve and 80 Plus just means it should be at least 80% efficient across that curve. It can be more efficient, so it'll probably be better than 80% at 'full' power.

Ramhound

I thought something was off with my logic. Power calculations have all been theory based, and I sucked at those, I am still confused the simplest problems from Circuits I :-)
