In thermal engineering, the organic Rankine cycle (ORC) is a type of thermodynamic cycle. It is a variation of the Rankine cycle named for its use of an organic, high-molecular-mass fluid (compared to water) whose vaporization temperature is lower than that of water. The fluid allows heat recovery from lower-temperature sources such as biomass c...

Oh well there's not enough heat to be worth it then lol

maiden coyote
#

That's neat.. I think the way that works is you have a heat pump ( ac ) and your evaporator is on the heat source.. so it's boiling refigerant absorbing heat from the souce. then you'd boil water on the condenser and spin a turbine.

soft bloom
#

the important bit is that
1 it can occur naturally
2 isotope ratios can be affected by it
3 there are heat sources inside Earth that are not just heat storage from the time Solar system was formed

#

its not so important. it was a rare event that happened in a blip

#

it requires a very specific circumstance and woudln't happen anywhere other than the crust

soft bloom
bronze jasper
#

not really though

#

that's quite a strawman leap

soft bloom
bronze jasper
#

yes. thats why i said it

soft bloom
#

But didn't you jsut take an example of something and concluded that no other mechanism could create similar outcome?

bronze jasper
#

no. i'm using a complete understanding of how criticality happens and understanding that it wouldn't occur below the crust in any molten layer

#

you actually were the one to find one example of something and make wild conclusions about it occuring anywhere inside earth

soft bloom
#

I am simply referring to the fcat of how little is known about Earth's inner workings.

I mean, we have big picture, but that's it. And making absolute statements is no different from fisherman in Italy making conclusion that fish only thrives in his beautiful seas, because there's no fiah from Columbia, "what is Columbia anyway?"

soft bloom
dire igloo
#

As much of a fallacy as a strawman

dire igloo
#

aka a strawman

soft bloom
#

Becase, you can't blame italian fisherman for not believing, or just allowing a thought that there are many weird fish in other parts of the world, and much deeper, nad not only fish, if he doesn't saw it, or heard of it.

soft bloom
bronze jasper
#

one would infer

#

we have a better understanding of uranium chain reactions than an italian fisherman has of columbian seas

#

which is entirely why the video you linked can confirm that there was a natural nuclear reactor billions of years ago

soft bloom
# bronze jasper we have a better understanding of uranium chain reactions than an italian fisher...

Yeah, cause in II century italians didn't know about Columbia as geographic region.
That's the an allegory meant to point out that stuff we don't know that we don't know about it is exactly that, until we go and make observation. But for that usually we need at least know we don't know something. And error commonly made is assuming we don't have something we don't know about because we have something we know we know about.

bronze jasper
#

allegory, or strawman?

soft bloom
# bronze jasper allegory, or strawman?

Strawman implies intent to discredit.
I simply point out a flaw, i am not twisting what you said into aomething like... "Oh so you say it only happened in Africa and cannot be replicated in a lab?" Damn, i canct even strawman lol

Who said strawman implies intent to discredit?
Strawman means you invent an argument for your opposing side and disprove that.
The goal is to make a point without having to address counterpoints.

Whether or not that counts as discrediting to you, I don't give a shit.
You brought up some narrative or idea and then disproved that.
Unless that narrative/idea is an actual thing, that's a prime example for a strawman.

If you want to share cool science stuff you didn't know about, by all means do so.
But for the love of God, quit acting like everything is some kind of major breakthrough or shakeup or challenges some narrative.
Just share your cool science facts as what they are, cool science facts

dire igloo
bronze jasper
#

yeah. natural nuclear reactors were always theorised, but that uranium mine just confirms it did happen because of the isotope ratios. its cool but its not anything breakthrough about earth's geology. The crust is such a small part of earth this reaction would not have contributed significantly as a global heat source

#

if you were to scale an apple up to the size of the earth, the skin of the apple would be thicker than the earth's crust is

#

that's a proper analogy

dire igloo
#

If you scaled a pool ball up to the size of earth, its surface would be rougher than earth

#

Earth has a diameter of like 13000 smth kilometers at the equator but the distance between the lowest and the highest point barely add up to 20km

bronze jasper
#

yeah. its wild how tiny the crust is relative to the whole

dire igloo
#

(Mariana's trench being 11,000 smth meters deep and Mt. Everest being 8,848m tall)

bronze jasper
#

its wild to me that james cameron researched so much about the ocean for abyss and titanic, that he just decided to go down to the bottom of the marianas trench for fun

#

so i considered other sources of heat on the crust like wildfire. i found a study that said one wildfire can produce a few terajoules of energy. convert this to kilowatt hours and you have many 10s of thousands of kilowatts/h.

the natural nuclear reactor produced 100kilowatts/h during while it was going critical for 3 hours at a time, and then less while it was cooling off until enough water flooded the space to facilitate the criticality once again. so, for 10,000 years, it produced far less heat than a wild fire

#

the sun probably warms the crust more than that natural reactor did

#

The gravity of the moon warping the plates of the earth probably produces more heat than that natural reactor did

bronze jasper
#

yeah him an richard branson had a billionaire race to see who could get to the bottom of the sea first

night girder
#

Looking at some pictures right now. I was always wondering about the Mariana's trench.

#

Also, it seems we are more interested in space than the deepest points of our earth/ocean.

#

Which is a bit sad, because I think the ocean can be as interesting and has still some secrets to us.

#

Especially at that depth, creatures that live that deep must be able to live with that pressure.

bronze jasper
#

Space is easier to see. There's a lot of money being invested into ocean exploration, it's just all corporate oil drilling and trade secrets

night girder
#

Like whales ribcages, they are flexible because of the pressure, they can bend in a bit.

bronze jasper
#

subs bend a lot too. theres a funny scene in "down periscope" about it

night girder
#

I think they must bend. Else 💩

bronze jasper
night girder
#

Apparantly this is a picture from James Cameron expedition

#

That almost looks like an alien to me 🤣

bronze jasper

he based a lot of avatar 2's designs on what he found i think

awww that clip i found doesn't even show the funny dive test part with the string

#

i've heard its one of the most accurate submarine movies out there though. worth a watch

night girder
#

Man, this is the worse sub and crew ever 🤣 Lucky it's a comedy so it works

#

Really? accurate?

bronze jasper

oddly enough yeah

night girder

There is two dudes ice skating on their knees

well like, theres some slapstick involved

night girder
#

Sorry, I know what you mean.

#

Humor and realism can go hand in hand, hard to know what is what sometimes though 😛

bronze jasper
#

okay i looked it up an i was misled on it's accuracy. but it does borrow a lot from reality still

night girder
#

For some reason, I think a submarine scares me more than maybe a spacerocket.

bronze jasper
#

the ocean is like a tight fist squeezing you so tight. like SO TIGHT. space is just , being wayyy to not squeezed

night girder
#

both are super deadly for humans though

bronze jasper
#

space ships have to handle squeezing between 0-1 atmosphers where subs have to handle something like 100s of atmosphers

night girder
#

Maybe it's because of that stupid playstation controller submarine that I am more skeptical

#

oceangate?

bronze jasper
#

lol they use xbox controllers on real submarines. it's a legitimate interface for their needs

#

oceangate was dumb for many other reasons

night girder
bronze jasper
#

navy figured out that all their recruits know how to use xbox controllers already, so they incorporated them

night girder
#

I can't believe a military submarine is controleld by a xbox controller. I don't think they will have a few billions be only controlled by a simple controller.

night girder
#

But the controller was just foreboding to me 🤣

bronze jasper
#

carbon fiber is what clued me into it would be a disaster. i wasn't surprised when that happened. i was following it a bit leading up to the disaster

night girder
#

such a tragedy

#

and as far as I know, nothing changed so far to prevent these things? But not 100% sure.

bronze jasper
#

they shoulda done like 100 dives to shallower depths without passengers, before trusting it. especially since it was such a new approach to deep submersibles

#

any testing really

night girder
#

I just wished we could have prevented this somehow.

bronze jasper
night girder
#

Especially that "costumers" died. People who paid for it.

#

That's my main issue.

bronze jasper
#

if you outlaw stupidity, only outlaws will be stupid

night girder
#

If the sub would have imploded on it's own. I wouldn't care. But people paid. And died.

bronze jasper
#

yeh international waters though. hard to have any laws out there

pure karma

looks like a beaver mixed with a butterfly

night girder
#

It scares me a bit lol.

night girder
bronze jasper
#

the owner was insistent on doing it even after his lead engineer quit. if there were laws saying he couldn't, he would've just sold people a boat ride then sell the tickets in international waters

#

his clientel were millionairs. not exactly the type of people who think laws matter to them if theres a way around they can afford

night girder
#

Yeah, I know.

#

But millionairs or not. They didn't deserve that.

bronze jasper
#

yeah i agree. fraud sucks.

night girder
#

Eh, I should look into it.

bronze jasper
#

especially when it takes lives

night girder
#

Maybe something did change. Laws or something.

bronze jasper
#

there's at least a LOT of awareness now, and other millionares won't be so eager to get into a submersible that hasn't been tested

bronze jasper
#

they'll be like "Waaaait a minute"

aight, let me look it up

bronze jasper
#

in the futuer, people will take submersible down to see the ocean gate wreckage among the titanic wreckage

night girder
#

This simulation is brutal. Not posting it.

#

And some people said when it happened they didn't believe it imploded.

#

because of some sound they heard, another submarine picked it up or a ship with sonar.

#

While this simulation clearly shows, it imploded.

at that depth it couldn't have done anything but crumple

@pure karma I wanted to ask to make sure that the gpu will actually work with that motherboard.

congrats on the kids tho. thats how i afford the high end of mid range gaming. i dont have kids

the only possible issue i see here is to make sure clearance is all good

yeah PCI-E is quite standardized these days. if you're buying one of the brand newest top of the line GPUs, you might wanna check that all the features work in the mobo, but that's not the case here

since your using an air cooler so clearance with the ram could be an issue and also have no idea what case your planing on using

yeah physical dimensions are more of a concern but low-mid cards like a 3060 are usually standard sizes. nothing oversized

i had to gut a bunch of my case when i got the 4080

I always thought that "Cloudy with a Chance of Meatballs" animated film was the one that 'invented' motion capture of the camera as technique for that one scene
but, as it turns out, the "Surf up" used it way more and got into theaters 2 years before that
anyway, that really helped with mocumentary perspective, together with voice acting in groups and improv, created quite a unique good mood for the product.
||I guess listening to allegedly 'surf rock' does steer recommendation a bit...||

9060 xt 8gb should cost around the same but be decently faster.
unless you are worried about the vram

safe trench
flint magnet
#

@ivory rampart I went with the 3060 because of the vram I looked at the 9060 but from what I was reading there was better performance for satisfactory with the 3060 because of its vram so ultimately I went with it

ivory rampart
#

yeah the vram on current low end cards is criminal

#

its such a shame.

#

both the 5060 and 9060 xt should just have been one 12gb card each

or 16, but thats wishfull thinking

Some day, some day ill build the super computer of my dreams lol 16 would have been nice

yes but its more expensive and might be over his budged

ivory rampart
twin dew
#

12GB vs 16GB is few tens of dollars chip price difference.

ivory rampart
#

for nvidia, but u know they would charge 10x hat to the customer

#

so there could be a thing as too much, if it makes the card more expensive than it needs to be

glossy glacier
#

At least AMD only asks for 50€ for 8GB more VRAM instead of Nvidias 100€ 🙃

verbal raft
twin dew
#

RX 9060 (XT) has 128 bit VRAM bus.
For 12GB of VRAM, you would need either 96bit or 192bit VRAM bus.
Where that 96bit would gimp performance, and 192bit would make the main chip and PCB more expensive.

ivory rampart
#

well to be fair, didnt nvidia start cheapingout on the buss width 2 generations ago?

128 used to be 50 class not 60 class.

so this realy is 500% nvidias fault

Nah, large part is "optimizing" the VRAM performance to the GPU performance.
Where the performance for same width VRAM bus has been going up faster than GPU core performance.

Or tricks that have lessened the need for raw VRAM performance with larger and/or better caches etc.

#

from technical and not windows bullshit standpoint : this will trigger trimming
which allow the ssd to internally reclaim its unused memory cells so it can write to them

bold tapir
wanton orchid
#

no

#

if it's an old ssd this may have low impact

bold tapir
#

doesnt seem old,

#

cheap tho

wanton orchid
#

seller announce 480TBW
so if you are getting close to that number, the ssd will have not a lot of healthy memory cell to write to

glossy glacier
wanton orchid
#

way worse even

#

this is an old work around for source hdd performance problems
this is very useless and bad for ssds

#

you basically going to write files twice

#

there is no magic to unzipping, the OS read the zip file then write the uncompressed files elsewhere

twin dew
#

Yeah, just bypassing how bad Windows Explorer is in copying small files.
Which usually isn't needed with SSDs that have no real seek-time anyways.

wanton orchid
bold tapir
#

ok gonna get crystaldisk

wanton orchid
#

it's also a good software if you are inspecting disk problems anyway

#

it will give you what problems the ssd report

it should be reported somewhere

twin dew

bold tapir
#

ah defragmentation

wanton orchid
twin dew
#

So might just be doing lot of extra work to actually write the data to TLC NAND it has.
When it doesn't have any completely free erase sectors, so it has to consolidate data.
And if it hasn't gotten TRIMs, might be even worse.

Windows should run that full drive TRIM once a week.

bold tapir
#

ok i did optimisation thing

wanton orchid
#

please check provisionning in the crystaldiskinfo

bold tapir
#

where do i check it

wanton orchid
#

below what you screenshot, you have a lot of actual detail

#

there are values showing provisioning usually

bold tapir
#

is it broken or something it says 100 everywhere

wanton orchid
#

it's common

#

although I agree it's hard to read

#

some values decrease some value increases

bold tapir
#

ah so 100 is good

#

so my ssd isnt dead but its crappy in general

wanton orchid
#

it does not report any provisionning use, but I think its lying
it reports -16%

twin dew
#

Depends, those actual values aren't standardized in any way.
100(%) is often "perfect" for most drives, but not always.

wanton orchid
#

you can think of it like if your ssd maximum size is now -16%

twin dew
wanton orchid
#

then why is it so slow to recollect ..

twin dew
#

Those minimum and maximum erase counts tell how often least and most written areas have been erased, which is that life limiter for writes, in hex in this case.

bold tapir
twin dew
wanton orchid
#

35MB files isnt really small

bold tapir
#

so i thought

wanton orchid
#

anyway sounds like after trimming it should be better

twin dew
#

So most erased flash cells have been erased 203 times, and least 58 times.

bold tapir
#

i mean pcie m2

twin dew
#

M.2 can be both SATA or PCIe/NVMe.

bold tapir
#

yes, i mean second thing

twin dew
#

And SATA with DRAM are usually much better than DRAMless SATA ones.

bold tapir
#

makes sense

#

will cheap pcie m2 have dram?

wanton orchid
#

no

bold tapir
#

cuz now i know cheap sata ssd doesnt

twin dew
#

But that HBM (using main system RAM as on-drive DRAM replacement) helps a lot.

wanton orchid
#

but the price line for dram isnt really defined, you can find more expensive ssd without dram

wanton orchid
twin dew
#

Basically as very big generalization:
DRAMless SATA -> NVMe without DRAM (almost nonexistent now) -> SATA with DRAM -> NVMe with HMB -> NVMe with DRAM.

bold tapir
#

can acronis encryption influence speeds?

twin dew
#

Yeah, sorry, HMB

wanton orchid
#

makes more sense

bold tapir
twin dew
#

Yes, any encryption can affect speeds when encrypting or decrypting.

wanton orchid
#

yes, depending on your cpu, I did note your cpu was saturating some threads, but should not be impactful for 35MB writes usually (without encryption)
at least not THAT impactful
but if you are doing weird encryption schemes, then maybe

twin dew
#

Depends on the encryption/decryption code implementation too.

bold tapir
twin dew
#

When done properly, not with current CPUs.
But done badly, can still cause major issues.

bold tapir
wanton orchid
#

is there any pcie/graphic card processing in background ?

bold tapir
wanton orchid
#

they can, marketing

Vs NVMe HMB:

NVMe Host Memory Buffer (HMB) feature added in version 1.2 of the NVMe specification. HMB allows SSDs to use the host's DRAM, which can improve the I/O performance for DRAM-less SSDs. For example, HMB can be used for cache the FTL table by the SSD controller, which can improve I/O performance.

EU chat control is going to be implemented because of idiots who keep saying "If you did nothing wrong, you have nothing to worry about"

pure karma
charred relic
#

I’ve done so much wrong…

quasi citrus
pure karma
#

ai leaking passwords is probably inevitable

#

im just curious when it will happen

bronze jasper
#

that's more of bad system design which is ALWAYS a problem. If AI training data has up to date username password combinations, then something went wrong waaay higher in thechain before it got to the chatbot level. I'd put it on the level of sql injection techniques. SQL injection being a valid attack doesn't make SQL a bad tool

dire igloo
dire igloo
dire igloo
#

The only thing you gain from having access to the hashed passwords is circumventing rate limitations - you can brute force the passwords locally by running your attempts through the same hashing algorithm (assuming you know which one it is) and seeing if the result matches

bronze jasper
#

also assuming you know the salting that the base code uses

dire igloo
#

tbh, I considered that to be part of the algorithm

#

in order to store a hash, the salting has to remain unchanged - so you can't use smth like system time

bronze jasper
#

thats cause you know netsec it seems and take that for granted. but so many backends just hash the password through the hashing algorithm raw with no added salt. so many bad developers out there

dire igloo
#

tbf, I'd take an unsalted hash over a password database any day

bronze jasper
#

yeah even with how proliffic rainbow tables are, raw hashes are better than plaintext passwords

dire igloo
#

But then again, even a salted hash can be found out.
Salting a hash is essentially just security by obscurity

bronze jasper
#

obscurity is more like using an unknown lesser used hash algorithm that's obscure. salting is further obfuscation

ivory rampart
twin dew
#

That per username salt isn't really sensitive information, and is expected to be leaked at same time as the hash itself.
But instead of using generic rainbow table as you can when there isn't salt used, with salt, each salt input needs separate cracking run.

bronze jasper
#

i just proposed the 90 degree tic tac toe to chatgpt and asked it if anything changes from the player's perspective. Turns out it's just a tool and not doing the thinking. the operator has to prompt it properly to get the proper information from it

bronze jasper
twin dew
#

So if there is no salt, and common algorithm with common settings is used, you can use precalculated rainbow table to go for all the passwords from the service.
No salt and uncommon set of settings, need to do cracking per service.
With salt, you need to do all the cracking per salt.

bronze jasper
#

yeah if you do a salt like the account creation date, each one having a different salt then, is best practice

twin dew
#

Basically without salt, it is worth it to run through the hashed set to certain password complexity, to get all the "easy" passwords from all the users, often using already calculated rainbow table.
With common salt, you need to recreate that rainbow table first.
And with per user salt, often not worth it except as targeted to specific accounts you are interested in.

bronze jasper
#

gotta think like a black hat to be a good white hat

dire igloo
dire igloo
bronze jasper
#

its demonstratably more hard than a default algorithm. stop arguing this point.

twin dew
#

Everyone always wants to use precomputed rainbow tables, even with single password, if possible.
And almost no-one is interested only in single hash from leak of service.

bronze jasper
#

the cases when people mock security by obscurity are when things like using mac or linux are lauded because it's more obscure than windows.

"just security by obscurity" is actually a very naive thing to say because good practices are often obscuring what's available to the hacker, which is a good strategy

dire igloo
bronze jasper
dire igloo
#

Precomputed rainbow tables only work if you know what algorithm was used.
The attacker not knowing how a part of the security system works at least to me constitutes as the definition of security by obscurity

twin dew
#

And you cannot crack any hash without knowing which algorithm was used with what settings?

bronze jasper
#

you can get rainbow tables for common passwords for any algorithm, and if a common salt is used, you just calculate the rainbow table once more for the common passwords and phrases

dire igloo
#

And that's my point: if you don't know the algorithm, you can't tell if it's an uncommon unsalted algorithm or a common salted one

bronze jasper
#

i'm just repeating what baldur said though

twin dew
#

And point was that salt is always with the hash.
So if one is leaked, the other one will be too.
And almost certainly if you get access to the user data table, you can get access to the code doing the hashing on login, to determine the hash and settings.

bronze jasper
#

its generally accepted in the network security community that saving unsalted hashes is a bad practice. i'm not sure why anyone would argue in favor of them

twin dew
#

But point of both common salt, and per user salt, is to make the actual mass exploitation of the leaked hash data much more costly in terms of computing power needed for cracking significant amount of users.

bronze jasper
#

which to my original point, of course bad practices will happen with AI tools, because developers still insist on doing bad practices regardless of the tools they have available

dire igloo
#

I'm arguing that for a single password, an unknown hash is no different from an unknown salt

#

Which is true as Baldur elaborated above

twin dew
bronze jasper
#

the vast majority of attacks are bulk

twin dew
#

And point of that per-user salt is to turn that bulk cracking into per-user cracking.

bronze jasper
#

unless you're a millionaire that controls a significantly valuable system, a targeted attack is very unlikely

dire igloo
#

If we go back to the original case, that kinda does matter - if an AI system has access to a user's hashed password, that's a singular case.

It means that there's general access to the entire DB tho, so it kinda depends how the AI access is built

twin dew
#

And for common salt is to turn using generic rainbow table to needing to generate salt specific rainbow table.

bronze jasper
#

yeah the fictional scenario with AI has never happeened and will already widely be considered to be bad practice. do not give your chatbot access to the authentication database

dire igloo
#

The whole discussion started from bad practice regarding AI system access

bronze jasper
#

it started when i saw someone making up a scenario about how AI will leak passwords, and i elaborated on why that isn't an AI problem and is just a bad system design problem as usual

what's a reliable way to change the GUID of a partition and update the windows bootloader config to point to it?

glossy glacier
#

honestly? don't go that way

visual tree
#

Speaking of partitions, I recently found my first USB stick I bought. It has 128 MB

#

It has 2 separate partitions and can't merge them for some reason but don't really care. Can't really do anything with 128 MB these days lol

sterile plinth
# glossy glacier honestly? don't go that way

I am trying to move my windows partition to another drive. To do that, im cloning the windows EFI and C partitions over to my 2nd drive. The problem is that both drives will have a copy of the windows installation with the same GUID

visual tree
#

And 128 MB stick was really expensive at that time I bought it

sterile plinth
#

which will cause conflict

night girder
#

I am sooooo happy I got YT to help me out for this.

#

Also, why the fuck are there so many videos, of people "teaching" how to press F5.

sterile plinth
#

laptop keyboards need FN

night girder
#

I think I am going to make a YT series. A video for every button.

night girder
sterile plinth
#

if you buy a laptop/ non full keyboard for the first time in your life nobody really tells you what the Fn key does

night girder
#

And I should put an add in after the first 2 seconds. Videos will only be 5-10 seconds anyway.

sterile plinth
night girder
#

sterile plinth
#

be honest did you read your laptop's manual the first time you pressed an f5 key in your life

#

someone else just tells it to you

#

if you dont have that somebody else, you look it up online

night girder
#

Nah, I learned to read manuals. As a kid I was stupid. As an adult, I am still stupid, but less stupid lol.

glossy glacier
sterile plinth
#

Clonezilla cant clone to smaller drives

night girder
#

Speaking of one who said I should read manuals... incomming!

sterile plinth
#

unless you have another suggestion for cloning software

twin dew
#

Normal Windows partitions don't even have that, just that the EFI partition contents refer to specific GUID.
Which is the problem, if there are two partitions with same GUID in same system, all hell breaks loose.

glossy glacier
#

i know the recovery always has the same GUID
i think the C partition too

twin dew
#

No, again, identifiers, not primary GUID.

night girder
#

I think I might order a bird instead of messing with AHK.

#

With a mechanical keyboard, and sensitive keys, this actually might work.

twin dew
#

There is the GUID, then there is the format type, and then there is additional "GUID type" identifier for usage with fixed agreed codes for things.

sterile plinth
#

Finding software that edits the guid of C drive in the windows bootloader config is not really easy

glossy glacier
#

double checked my script and yeah, its gpt type not GUID that has to be the same, my bad

sterile plinth
#

and it still is a risky operation

BCDEdit

twin dew
#

And with that you would normally just shrink the last partition so it ends before 1000GB mark.

#

And then expand it again on the new disk.

sterile plinth
#

A drive-to-drive clone from a bigger to smaller drive can't happen (with clonezilla)

twin dew
#

Yes, and to clone 1024GB drive to 1000GB happens by shrinking that last partition on the 1024GB disk to end before 1000GB mark.

#

And then Clonezilla will happily clone the drive, as long as the size difference is unused.

sterile plinth
#

I see

twin dew
#

Yes, better to make it more than the minimum.

pure karma
sterile plinth
#

and after cloning my 1st disk's contents to my 2nd's, I immediately delete the 1st disk's C partition on gparted before it boots up and fucks up the guids?

glossy glacier
#

physically remove it first/unplug it

twin dew
#

Or change the GUIDs on one disks partitions before rebooting.

sterile plinth
sterile plinth
glossy glacier
#

it is still bootable after a clone, you did not change it after all

sterile plinth
#

that's nice

#

i guess ill start shaving off space

glossy glacier
#

oh, and yeah, there is a chance the target is unbootable

#

make sure the clone works before deleting the source, thats why i recommend uninstalling/unplugging it

twin dew
#

Or like I said, just change the disk and partition UUIDs for the old drive while still in that cloning OS.

#

With partition editor of your choice.

sterile plinth
#

alright, gparted should be able to do it

sterile plinth
twin dew
#

So "Unique partition GUID"s seem to be changeable with almost anything...
But cannot find how to change the "Disk GUID" too...

sterile plinth
twin dew
#

Point was that it is "disk" identifier in the GPT in LBA1 of the drive.
Which gets copied, and should be unique too and not shared by two drives.

#

And then there are the Type GUIDs and Unique GUIDs of each partition, where the unique ones also need to be changed, but that is easy.

#

But haven't found right search terms to find how to change that Disk GUID, as just brings up how to change the partition unique guids.

sterile plinth
#

hum

#

well, hopefully it doesnt cause too big of an issue

sterile plinth
#

is there any easy way to prevent/easily do away with these

twin dew
#

That was with MBR type and classic BIOS boot.
Which worked with LBA offsets.

#

Not issue with UEFI booting.

sterile plinth
#

that's great

glossy glacier
#

speaking of disk cloneing, gonna have to figure out the best way to switch around two OSes on two disk, OS A from disk A to disk B and OS B from disk B to A >.>

"gdisk" can randomize both disk GUID and partition unique GUIDs.

For me, after some getting used to it, it made more "fun" to use than 10.
It had some problems in the beginning but was otherwise very stable.
I think my EU/German copy was spared most of the forced bloat, so I got lucky.
All the AI stuff at the horizon and the miss management from Microsoft made me switch to Linux a few months ago

sterile plinth
#

I am planning to upgrade to w11 soon though, is the German copy a different ISO file, or does your german IP give you less bloat during the online installation of windows?

glossy glacier
#

a different iso and our laws stopping most of the stuff I think
EU laws allow uninstalling most stuff too

#

And gaming is hugely dependent on the games you play
MMO PvP with anti-cheat? Windows only choice.
Most other games? Mostly work fine (thanks valve!)

wanton orchid

for anything not mm and without stupid "anti cheat"
it basically works now

the argument that it's hard to setup makes less sense now that you have to try multiple times to make it work on vanilla windows too
because anyway games and windows are shit

glossy glacier

Anti-cheats started fighting themself. Time for a seperate vminstall per game

mental oriole

Pretty much

bronze jasper
#

with the new bf6 beta, users were required to shut down valorant's anticheat in order to run bf6. a lot of "gaming journalists" said that ea was forcing players to uninstall valorant to play battlefield, but that was just clickbait sensationalism as usual. you only had to close it.

night girder
#

In the old days, games used generic anti cheat, sometimes you only needed to install 1 which could run for multiple games. This elevated the problem of AC suspecting eachother.
But it has drawbacks, like it's a single vector of attack, so once AC is bypassed, a lot of games lose their protection.

it's because publishers don't want to have to field support tickets from linux users that are probably having issues local to their own distro and system, rather than an issue with the way the game is made.

yeah spectating mode can use player cams. sometimes it uses fixed cams. they're less used these days because it became a trend for people to watch playercams of the enemy team and then call out positions over ventrillo

ivory rampart

That's my issue with most of this tbh, corporations can just introduce their own rules.
As long as they don't go against the law, they can request anything from you - you're free to refuse, but they'll just not serve you then

When people thought up the idealized free market, they just conveniently dismissed the possibility of a single party being able to threaten a refusal of service

Consumers should not be dependent on a company staying in business with them

the 1st drive has a good 30gb unused

twin dew
#

Ok, too bad.
Could just use raw dd then.

#

if you do, remember to set bs=1M or higher, so it doesn't do it one LBA at a time.

sterile plinth
#

I will use this command, looks promising enough

dd if=/dev/nvme0n1 of=/dev/nvme1n1 bs=1024M oflag=sync status=progress

#

I'm guessing it will just give me an out of bounds error when it reaches the last 24 gigabytes? (Which I can ignore)

twin dew
#

that oflag isn't needed, you don't want synchronize.
And that would try to copy 1GB at a time.

#

1 megabyte at a time is plenty.

twin dew
#

that 1M

sterile plinth
#

in general you want to do big writes at a time, don't you?

twin dew
# sterile plinth Isn't that faster?

It would read 1GB into RAM, then write it to the other drive, then synchronize.
With bs=1M, without that sync, it will read 1MB, write 1MB, as constant process.

#

That block size just needs to be large enough to be larger than the erase block size with SSDs.

sterile plinth
#

what I meant is, what makes 1M block size faster than 1gb

twin dew
#

With HDDs, that 1M size was near optimal.

twin dew
#

Because DD would read 1GB, and ONLY then try to dump that 1GB as one write to the second drive.

sterile plinth
#

i see, so by doing little at a time it keeps a consistent pace

twin dew
#

dd if=/dev/nvme0n1 of=/dev/nvme1n1 bs=1M status=progress

twin dew
sterile plinth
#

I read somewhere it's good to fstrim the target drive to empty it before doing the clone, I'll do that too

twin dew
#

sync only matters to protect against power losses.

twin dew
sterile plinth
#

Or do the Io operations slow the system down completely

twin dew
#

But point why that 1 megabyte block size has been the recommendation for long time, is that it is large enough to basically get full performance from any drive, and small enough to still get full performance on any drive without the drive having issues with too large size.

twin dew
#

You get broken file system if you do.

sterile plinth
#

Oh you're right, data might get changed while I'm reading it

Yeah, file system metadata wouldn't be from same state for whole drive.

Just having one drive redundancy is bad idea with HDDs these days, if you care about the data.

mental oriole

#

so are datacenters largely not using those huge HDDs?

twin dew

No, going just with more redundancy.
So they can take one or more drives failing and then still be able to deal with read errors on another.

pale flame

So for example not using RAID-5, but RAID-6, or with ZFS not using RAID-Z1, but -Z2 or -Z3.
Or various versions of RAID-10 with more than 2 drives per mirror etc.

languid gulch

yeesh

Same even with smaller drives in 10TB size range etc.

languid gulch
#

oh just in general

#

since my external 8tb dropped dead, i'm mildly nervous about my now oldest drive

#

wondering if i should go for a big fat drive or a smaller one that has a better reputation

glossy glacier
#

I see. Yeah if they are not in some kind of raid, stick to the smaller ones

twin dew
#

Planning to get 6x 4/6TB drives in RAID-Z2 for my own NAS once I can afford that.

visual tree
#

My NAS has been showing hdd bad sector warning for one of the drives but somehow it's still working lol

#

I have RAID mirroring so in the worst case, only one of the drive will go out soon

#

Theoretically, both drives could go out at the same time but that's a very rare scenario IRL and I'm willing to take a risk

pale coral
#

RAID is not a backup imo, if you have a failing drive it's going to spread bad data to the other disk.

#

RAID is to increase server reliability & mean time to failure of a node. My personal backups do a disk health check then backup every day, better to use a drive as an actual backup than put it in an array.

twin dew
#

That is the point of ZFS and BTRFS with actual data checksumming and integrated multi-drive functionality too.
But still not backup.

#

Or combination of Storage Spaces and ReFS on Windows.

pale coral
#

++ZFS, haven't seen that acronym in a decade since I went a non-network path lol

visual tree
#

I mostly use NAS for storing data even though NAS offers much more than just data storage. Not sure If I should pay for google drive at this point since getting new hard drives and a synology NAS soon will cost me as much as paying for google drive (2 TB) in 5 years

#

*under the assumption I get fiber soon

Including that Windows Storage Spaces.

-# what the fuck

sterile plinth
#

@twin dew done with dd, but the partition table doesn't really seem to exist

twin dew
#

Refresh that, or close and reopen it.
Or might be bugged because of those identical IDs causing Linux to freak out.

#

what does command line blkid say?

sterile plinth
#

Fdisk says the disk uuid is 0x000000

#

that's obviously off

twin dew
#

What copy command did you use?

sterile plinth
#

sudo dd if=... of=... status=progress bs=1M

twin dew
#

point was to see the device names specifically.

sterile plinth
#

/dev/nvme1n1 and /dev/nvme0n1

#

The 2 block devices

#

The 2nd one was the input of course

twin dew
#

nvme0n1 to nvme1n1?
Then see what that gdisk /dev/nvme1n1 says?

#

Or like that fdisk shows for that drive, that the GPT is seen as invalid and would be fixed by running fdisk /dev/nvme1n1 then just writing.

#

Without changes.

sterile plinth
#

alright, fdisk does recognize 5 partitions it seems

#

Using the i command it allows me to see info about each one, nothing seems inherently wrong

twin dew
#

Yeah, it was just that the full GPT disk size is/was invalid, as it said the last LBA is the end of the larger disk.

#

If you look at that red line in the fdisk -l pic

sterile plinth
#

It does say it was corrected by a write though

twin dew
#

As long as the last partition end LBA is smaller than that disk end LBA, all is fine.

twin dew
#

It doesn't do it until you tell it to.

#

w to write and exit.

#

p to see the changes before.

sterile plinth
#

Um, I just did fdisk -l

#

I'm not inside fdisk

#

so I think it automatically did the write for me

#

Since it said "will be corrected"

#

Maybe a 2nd restart?

twin dew
#

That -l shouldn't have done a write.

#

run "fdisk /dev/nvme1n1", then use l command inside, then p command inside, and then if the changes seems fine, use w

sterile plinth
#

Done, not much changed

twin dew
#

but does blkid and/or fdisk -l now show the partitions?

#

or lsblk

sterile plinth
#

no, in fact if I enter fdisk a second time it shows the same mismatch

#

Maybe "will" implies it is scheduled for the next system reboot? I will try that

twin dew
sterile plinth
#

also getting this on gparted

sterile plinth
#

and the l command lists all available filesystems

twin dew
#

Ah, sorry, wrong one then, moment.

sterile plinth
#

Can't find one which shows changes

twin dew
#

Ah, yeah, there isn't.

sterile plinth
#

Anyway fdisk still says stuff about the mismathc

twin dew
#

But I did ask you to see what that gdisk says.

sterile plinth
#

Gdisk did recognize all 5 partitions from the start

twin dew
#

Which is GPT edit utility.

#

But doesn't complain about size mismatch?

sterile plinth
soft bloom
#

So, today PSU decided to be more naughty
It stayed off the grid for like 8 hours
And it didn't do anything when power returned and power button pressed
Like no sound at all
And only after trying all permutation off "connect grid, toggle switch on psu, press power button" a couple times it finally came to life

sterile plinth
#

It does give me a lot of potential fixes

twin dew
# sterile plinth

Yeah, so seems GPT uses last LBAs for secondary copy of GPT, and those are now missing, as they didn't fit.
So the first GPT needs to be adjusted and new secondary ones created.

What does r menu say? (recovery and transformation)

#

But seems the right one is x for expert, then e to move the stuff to current disks end.

sterile plinth
twin dew
#

Yeah, for three of the four points.

sterile plinth
twin dew
#

Ah, yeah, sorry, was reading through the man page, and that x (expert mode), then e (move backup GPT to current disk end) is the right step, and is suggested as three of the four points.

sterile plinth
#

Alright, let me start with that

twin dew
#

Then need to see if it still complains about that third point or not.

sterile plinth
#

Okay done that, now I will write changes with w

#

lsblk shows the partitions

#

Gparted does too

#

that's good, I now only need to change uuids

twin dew
#

And now you want to use that gdisk on nvme0n1, then x, f

#

f

Randomize the disk's GUID and all partitions' unique GUIDs (but not their partition type code GUIDs). This function may be used after cloning a disk with another utility in order to render all GUIDs once again unique.

#

And check that verify again on the nvme1n1 now.

sterile plinth
#

done that, fdisk shows the new uuid

#

verify is clear too

#

hmm thinking about it, I did just accidentally randomize nvme1n1

#

no worries, I'll just manually put in the uuid from 0n1

#

Using the "t" command in gdisk

twin dew
#

Need to use that gdisk expert mode to change drive ID and partition IDs to the ones from the original disk.
Then check they all match.
And then randomize the original disk.

#

c to change partition UUID

sterile plinth
#

And g to change disk uuid

twin dew
#

Yeah

sterile plinth
#

I only need to change the windows partition's uuid back to the original, the rest are not bootable anyway

#

They can stay randomized

twin dew
#

Didn't want to take any risks.

#

Probably don't matter.

sterile plinth
#

Uuid too short for some reason

twin dew
#

That PARTUUID

sterile plinth
#

Right, my bad my bad

twin dew
#

Ah, don't.

#

That first was EFI partition with FAT, moment, need to check.

twin dew
#

Checking that that isn't by mistake the Type ID, which is also GUID, but with fixed values based on usage

sterile plinth
#

nvme 0n1p2 doesn't have a part uuid at all

#

It's a Microsoft reserved partition so I won't bother

twin dew
#

Which tells that that is the wrong thing...
As all GPT partitions have the partition UUID.
Need to check that blkid documentation to see what is what.

sterile plinth
#

this specific partition is unrecognizable by any Linux tool

#

It's a Microsoft thing I'm guessing. I have never seen gparted recognize it properly

twin dew
#

Yeah, because it is just empty space.

sterile plinth
#

flags "msftres"

#

Microsoft reserved

#

Anyway if it doesn't have a uuid then there is no issue

twin dew
#

That MS reserves for partition size changes with OS updates.

sterile plinth
#

so I reverted all the uuids back to original and randomized the uuids of nvme0n1

#

I think it's time to see if it boots?

#

Nothing else I can imagine could go wrong. I'll try to boot rn

#

Alright I see windows loading thing

#

I'm in

#

lovely!

#

now time to wipe everything other than c drive

#

After gym that is

#

@twin dew thanks a lot for all the help

I found an unpartitioned drive in my computer using Disk Management recently

#

My current build is so old its got its own archaeology expeditions.

i got like 4 old HDDs in my pc just cause they're still working and i got the ports for them and a 1000w psu. but yea, it tunrs out for like a year, i was running without one of the 1TB drives being properly partitioned

for an all black 1440p high-ultra pc build what would be a better case?

dire igloo
# safe trench for an all black 1440p high-ultra pc build what would be a better case? plannin...

CPU/MB I assume microcenter deal
Overkill AIO, probably also overpriced/mediocre
Overpriced RAM, meh for manual OC
Overpriced PSU, probably overkill too
Can't speak about custom cables, feels overpriced tho
No SSD in list

As for case:
Can't speak for Okinos quality, from what I've seen generally quite cheaply made.
Antec one is fine from what I remember

Can consider Lancool 217 too:
https://pcpartpicker.com/product/rXnXsY/

For AIO, my picks would be ID-Cooling FX360 Pro or Thermalright Frozen Edge

#

Or for style

#

Nah, manual tuning for RAM can go a long way without major losses in stability

#

AIOs are not cost effective and are only worth considering for one or more of these reasons:

  1. Aesthetics - You have money to spare and are willing to spend it for style points
  2. Space - Your case's formfactor wont fit a powerful enough air cooler (tho you should probably re-evaluate your choice of case)
  3. Performance - You frequently load a power hungry CPU (overclocking, heavy productivity) requiring a highend cooler
#

There's a HUB video where they applied Buildzoid timings.
Tuning 5600 MT/s RAM gave bigger benefits than going to 6000 cl30

#

That do be true, yeah.
Most people don't care enough

#

Anyways, gotta go wirk

safe trench
#

i like how they look

i just need to add rgb strips all over then i will gain 9000 fps jace_smile

not too big of a problem with an aio tho

#

you are acting like im hard lining this with custom built pipes and 0 knoweledge

#

im getting a microcenter bundle genuis

the ram is also included with the bundle

no one said anything about your ssd. enjoy your mid pc

at this point i think it's a fantasy build that'll never happen. you're too offended by advice

failures are usually much less dramatic and just the pump dying

safe trench

#

lol using discord client mods so you odnt need to remember the deleted post, but you still can't read it right. i never said leaks

#

it's a fact that pumps failing is a lot more common than air coolers failing

#

and a mid range gaming pc won't even need liquid cooling. it's just a gimmick and speaks towards the fantasy build aspect

sorry for me not using a aircooler for everything ig

the ram wont have a bundle discount

dire igloo
#

Your points kinda sucked too btw.
They said it's using microcenter deals, it was quite obvious that it was a CPU/MB bundle. Also: where'd you get that shared polling info from? First time I'm hearing it

bronze jasper
bronze jasper
#

just an example of B series boards having cut corners compared to X boards. shared lanes were undocumented but caused a LOT of problems

#

who knows what undocumented compromises are done these days

safe trench
#

wdym polling info

dire igloo
bronze jasper
#

Gigabyte tho

dire igloo
# safe trench wdym polling info

Shared PCIe lanes.
It's when some connectors on your motherboard use the same pcie lanes to connect to the CPU or chipset.

One common but old example is m.2 slots and SATA ports being mutually exclusive

dire igloo
# bronze jasper Gigabyte tho

It's fine. And let's not forget that ditching it for a different board will lose the bundle savings

As you said, overclocking isn't really a consideration here.
And for general use, that board is more than good enough

dire igloo
# safe trench the ram wont have a bundle discount

iirc that basically means you play full bundle price for only CPU and MB.
$120 for that kit is hella overpriced, 2x16gb DDR5 shouldn't go into the triple digits, you can commonly find good kits below $90

dire igloo

# dire igloo And this link returns an empty list for me, idk why

# safe trench crucial

Ah okay, had the patriot one in mind, crucial's is a much better drive.
Still QLC NAND tho, but some of the best QLC out there

#

I didn't check their other deals tho

dire igloo
#

Note that the Century II may not have any custom cables available for it.
Extensions exist but they create extra resistance which can lead to instability in niche scenarios.
Overall, no point for them imo, save yourself the cost

safe trench

wait never mind im not getting these are cables not cable extensions

dire igloo

not necessarily a bad pick tho, plenty blackout air cooled builds exist

Just two examples

are cable extensions one of those things you can cheapout on?
