Transmission-daemon 2.92 is in the official raspbian/debian repo, 2.94 is the current version. How do I update it (private tracker doesnt support .92)?

a = 2, b = 6 k = (4 + 36)/(1+12) = 40/13, not a perfect square.
Elijah Martinez
k is not even a natural numver now you dumb fuck. Cant just plug in random numbers and see if it works, they have to solve the equation in the respective domain.
Xavier Jones
yeah, I'm on Kubuntu right now. How the fuck do I make a Win10 USB so I can get off this shit.
Nicholas Morris
Install GuixSD
Kayden Lewis
sudo apt install woeusb is the easiest and best program to use which I have used for the exact same purpose before in the past and would highly recommend.
OP is a fucking faggot. Given k a cube of a natural number, k can't be a square of any fucking natural number. Besides, if you use any random number meeting the requirement, e.g., a=8, b=27, the result k is not even a natural number. So feel free to solve your retarded equation and consider killing yourself.
Austin Ortiz
You either ignored the first line or were to dumb to know what it means. A, B and K have to be natural numbers.
Samuel Bennett
he was clearly trying to prove that k is natural if a and b are natural, it is not, therefore k is not a perfect square.
Leo Gutierrez
That's not how these problems work.
The problem states that for when K, A and B are are natural numbers K is a integer square of (a^2 + b^2) / (ab+1). If K isn't a natural number then ignore it is irrelevant.

this is the transmission plugin on freenas 11 I linked a directory from a samba share folder to a folder inside the jail, but it doesn't seem to work any ideas?
I've been trying to get Power Manager + Light Locker on Xubuntu to shut off my screen on idle but all they do is blacken my screen (I can still see the backlights, it's not actually OFF).
All these googling introduced me to Xscreensaver which people have been shit talking for some reason. I decided to install it anyway and it works the way I expected Power Manager to work. It actually turns off my monitor.
But I'm inexperienced, why is Power Manager and Light Locker installed by default? Is Xscreensaver not good?

virtualbox cannot emulate an amd64 cpu, your host (real) cpu needs AMD-V/Intel VT-d supported and enabled in the bios for virtualbox to use to virtualize the cpu instead
Bentley Richardson
ps. things like Qemu /can/ emulate a 64bit cpu, but remember cpu emulation is FAR slower than virtualization
Carter Bennett
Dang son how rude. Could have let me off easy. Is it this general problem, or just proving some equation is a perfect square?
Caleb Anderson
ℕ^3 is the set of 3D vectors with natural components, not the set of cube numbers.
I think (a,b,k) in ℕ^3 is just a smartass way of saying that they're all in ℕ since they form a ℕ^3 vector.
Thomas Phillips
this meme is so old and dead its not even shitposted on /sci/ anymore

it's not a vector space so you can't call them vectors it's actually standard notation, though you are more likely to see something like a,b,k all natural numbers rather than (a,b,k) in ℕ^3 especially in highly non-formal texts like computer science books
Carson Foster
Google it. Problem 6, IMO 1988. Terry Tao did the problem at that time, when he was 13 ish. Think he only got one point though.
At my university (France), we use the two notations but we mainly use the (a,b,k) in ℕ^3 notation to feel smart.
Bentley Sanchez
So guys tell me if it's possible to install any distro on a surface pro 2?
Josiah White
Well fuck me
Henry Ortiz
k ∈ N wrong
Eli Ortiz
Oh, that looks weird. We didn't learn that in our country, so it's my fault
Adrian Cook
question towards the gentoo users out there: Is it possible to run gentoo with binary programs only? I mean for settup up gentoo for the first time it would probably better i think. Later, when I have my setup complete I would start to compile all the things on my own. Is this possible?
Justin Wilson
What thin laptop is good investment to get if I want to run GNU/Linux
>on Debian >want to learn something >check the Arch wiki >run instructions the Debian way

Is this normal?
Isaiah Long
>on Debian >check the Arch wiki I admit, I've done that too. I like Debian and I have no interest in running Arch, but those folks are really good at writing guides and documentation.
I experienced faster IP assignments with network manager switching from wicd
Connor Roberts
>Install GuixSD Install NixOS
Robert Moore
>it's not a vector space so you can't call them vectors
yes it is you dumb fuck. ℕ^3 is a vector space
Ayden Campbell
is the AUR secure? I mean I read on the memewiki inatallgentoo that not all packages are, and is what is keeping me from installing Arch. I'm not retarded there has to be flaws on the ubuntu's repository but probably not as much
Leo Russell
download an iso and dd to a usb?
Adrian Brooks
They're both decent, but NetworkManager has worked more consistently for me.
>ℕ^3 is a vector space It's really not. It doesn't even have additive inverses.
>GuixSD vs NixOS What differences are there? Every reference I can find for one talks about the other too.
Gabriel Sullivan
>It doesn't even have additive inverses. It's the only missing property
Logan Ward
just look out for things like rm -rf ~/*
Oliver Hall
Brainlet here, ℕ^3 is closed under linear combinations, so why wouldn't it be a vector space? Isn't that the only requirement?
Noah Walker
Is lubuntu a good distro for beginners?
Jace Hill
i once saw a script that fixed my 2 computer screens sides. i have my second screen on the left and if i turn on the pc before turning on the monitor, linux will place the second monitor on my right side and i have to manualy switch it everytime...
David Roberts
>Isn't that the only requirement? No. Consider 3x3 matrices under multiplication. That's closed under linear combinations, but it's a long way off being a vector space.
>Is lubuntu a good distro for beginners? Sure. It's not particularly pretty, but it "just works" and will run on anything more powerful than a toaster.
Evan Myers
Line 1 -> line 2: no idea what you did there
Also, the last step you do is wrong because there needs to be a 2 in the mixing term to simplify like that.
(a-b)^2 = a^2 - 2ab +b^2
Brody Sullivan
Do your homework yourself retard kid Also r/fglt
David Perry
So nobody here can solve it? /sci/ was right, CS (and Jow Forums) is full of brainlets. I mean, I'm a brainlet too, but I thought we had a few shitheads with more than 3 neurons around here. Anyway, the only people who solve this on their own are 1. Prodigy kids who "just get it" 2. Mathfags who memorized a types of problem archetypes
Am I supposed to be able to with just high school math?
Charles Sullivan
Matrices aren't vectors though. How does it make sense to say that they can be closed under linear combinations? They aren't in a vector space to begin with
Jaxon Moore
trying to format an usb, what file format should i use? i'm on manjaro linux, but i need it to be compatible with windows 10 for work
Carson Adams
>Matrices aren't vectors though >They aren't in a vector space to begin with Sure they are. mxn matrices (over any field) under addition form a vector space. They have addition with inverses, scalar multiplication, commutativity, associativity, etc.
>How does it make sense to say that they can be closed under linear combinations? Any linear combination of elements from the set will also be a member of the set. In the example I gave, if you multiply a bunch of 3x3 matrices together you'll get a 3x3 matrix.
Austin Bennett
Just use ntfs, it's surprisingly better supported on linux than fat. Works like a charm on any wangblows. What kind of work requires windows 10 tho?
Michael Ward
most non techy ppl dont take the time to learn linux, anything thats not WINDOWS or MAC is a big no no for them, and trying to talk to your bosses about switching to linux is even an greater challanger, imagine talking to a 50 year old dude who knows nothing about computer about this weird thing called linux that uses the terminal...people are dumb
Levi Stewart
Oh, I see, so the linearity of transformations applies to the transformations themselves as well as the vectors they transform? Or am I missing the point?
Daniel Torres
so i got the usb formated (ntfs) but its having troubles mounting on my laptop?!?!? its manjaro linux too...i'm kinda lost :| it reconizes the usb, but is just keeps spinning on what i assume is mounting...
Easton Robinson
>Oh, I see, so the linearity of transformations applies to the transformations themselves as well as the vectors they transform? That's not what I meant.
"Vectors" (in an abstract sense) are just any members of a vector space. A vector space over some field is a (non-empty) set with: a) A "nice" operation between it's members, called "vector addition". b) A "nice" operation between it's members and the members of the field it's over, called "scaler multiplication". c) Distributivity between a) and b).
Those conditions imply that every vector space is closed over all linear combinations, but just because some set is closed over all linear combinations doesn't make it a vector space.
Jacob Scott
It's a troll problem that's already been disproven here:
Ayden Richardson
Look at the replies - the question requires k to be a natural number.
Ian Cruz

Justin Taylor
every time i press the X button on specific programs (anything in wine, games, etc) it always, always says "this window is busy, would you like to close it?" of course i fucking want to close it if i clicked close, who is this feature for? is there any way to turn it off? i dont know what to google but i couldnt find anything
Juan Ross
typical dumbfuck manjaro retard. FAT32 for best cross-OS compatibility NTFS of maybe exFAT if you need large files fat32 doesn't allow. Pref. exFAT, NTFS is not optimal USB flash drives. The fuse-exfat driver is quite good and stable for years.
Connor Lopez
Pressing the X button usually just asks the program to terminate. If the program doesn't reply to it in a timely manner it means it's either busy, waiting for user input like if you want to save or discard your work or the program is frozen.
Joshua Green
is there a way to instead force it to send a kill? all the times the program is "busy" with exception of prompts it was working just fine and i happened to be done with it. i have to open task manager and send kill to everything or it just keeps running forever now or until it finally lazily pops up the "window is busy" crap. if sending kill removes prompts i will just have to learn to live with that
Hudson Ross
create a short to xkill to somewhere and use that to close problematic windows?

libgl1-mesa-glx:i386 but it is not going to be installed or libgl1:i386 but it is not going to be installed
Holy shit this fucking ubunt is grinding my gears down right now. Same distro one on my thinkpad, one on my destkop. Get this shit on the desktop but the laptop works fine. Now I'm purging everything just to reinstall. Hopefully that will fix it.
Wyatt Wright
i just found out this is bound to ctrl+alt+escape, thank you
try sudo apt-get upgrade
Cooper Rogers
dpkg --add-architecture i386 apt-get update then try installing whatever you tried to install
Aiden Stewart
>try sudo apt-get upgrade I did that 3 hours ago of course lol, Trust me this thing is beyond fucked. It gets into these weird states somehow and just stays broken forever.
Aaron Flores
Anyway I appreciete the help but I tried all that stuff already. Its not going to be simple fix

a number can be both a square and a cube though???? 64 = 8^2 = 4^3
Cooper Sanchez
try to manually install one of the packages. If you run into a similar problem, try to install the package that is not installed that time. Repeat it until you reach the root of the problem, which is probably a totally missing package, something broken, conflicting or something with a missing dep.
Mason Wilson
is your point that not every set that is closed under linear combinations (and non empty) forms a vector space? i.e a set of 3x3 matrices? That seems to be what you're implying here and here , But then here you say that sets of matrices do form vector spaces
Adam Sanchez
Yeah I'm thinking might be because I enabled the backports and couple other repos. Oh yeah forgot I installed nvidia driver right from the nvidia website. Didnt come in a deb package or anything. Maybe that wiped out some the packages that are supposed to be there.
Anthony Johnson
So I have installed ubuntu on a usb with persistence. Now that I booted it up in live mode I wanted to check something from my computer's hdds. But they don't show for some reason. Even sudo fdisk -l doesn't show them. The only thing I can see is the usb itself. Any ideas ?
Nolan Rivera

Benjamin Allen
>is your point that not every set that is closed under linear combinations (and non empty) forms a vector space? Yes.
>But then here you say that sets of matrices do form vector spaces Under addition. A vector space is formed by the combination of elements and operations. If you add matrices together then they form a vector space. If you pick some other operation (such as matrix multiplication) then they might not.
