Linux gaming was always slightly buggy for me for a while. Then I tried Nobara, and since then everything has been more or less plug and play.
AC Odyssey was a bit more work to get going but that was because I had bought it through Ubisoft Connect. But even that just needed me to install it in Lutris which comes preinstalled and made the setup nice and easy.
Nobara is developed by the guy who makes ProtonGE, as a side note.
When I switched I had to use Windows (gross) to make the boot disk. Turns out that was my mistake, Windows fucks with the drive just a tad and made the verification fail on the installer.
Using a live usb Linux stick I was able to download the ISO and write a new install disk. Worked flawlessly from there.
I switched from PopOs to Nobara, and it worked great but after a while my sound quit and I missed how switching workspaces worked in PopOs. I tried Mint and surprisingly I had a hell of time trying to get gaming working like it did, so I back to PopOs and I have zero complaints. Everything just works. I have a bunch of games that say no on the steam deck but they work great. I’ve been told the kernal is outdated but honestly, I don’t care, everything works. In my household we have 5 pc’s. My wifes is the only one left on Windows and she has more issues than me.
Quadruple dipping because they publish both open access journals that authors pay extra for, plus the standard subscription journals where universities need to pay for access too. Subscription obviously never got cheaper, no matter if the amount of open access journals increased (didn’t check that though, but fits well into the scheme)
I’m still not sure, what exactly the journals are actually doing.
Like, in all seriousness, what service do they provide? Just hosting the platform for anonymized reviews and basically a blog for the actual articles? That should cost maybe a few millions each year, yet this sector makes billions in revenue.
They offer reputation. Career advancement is highly dependent on publication history and impact. Getting into a prestigious publication means your work will more likely be read and cited. Because highly reputable journals can charge high publication fees (because it’s in such high demand), they get to set the industry norm, which other less reputable journals/publishers get to follow. It does cost money to develop and maintain that reputation for rigour and impact (i.e. good science). But yeah it’s exploitative AF. There are attempts for less profit-motivated publications… But making those rigorous while still being democratic is hard
I’d say (a couple years ago) the service is also supposed to be access via DOI in perpetuity and presence in all the relevant databases, so that’s gotta cost some money for the reassurance as opposed to a pdf file “hosted” on Google Drive. But after Heterocycles fiasco I am not sure about that anymore.
Still, yes, billions in revenue vs millions spent essentially on essentially simple tasks like hosting and cataloguing (plus matching authors to reviewers I guess, though with how often I am asked to find them myself it’s doubtful) does not compute indeed.
That’s a good question. I have a few devices that are Linux compatible but require Windows to upgrade the firmware. I don’t know if I trust Wine or Bottles enough to run these applications to update a BIOS. Or if it’s even going to work?
I can always update device firmware through a Windows VM, but not my PC hardware.
All fun and games until they all go extinct because their environment had a slight variation and they could not adapt to it because they’re all clones with the same genes
Its easy to think about vectors in the first sense (as anything with direction and magnitude) when we’re working with classical units (space, force, electric fields, etc)
But it becomes a nightmare to understand intuitively when the vector is defined as something with magnitude and direction when speaking about units that are not obvious to us humans (like time)
Thanks, but damn… I don’t even understand your explanation. 😥 I work with vectors in Blender, so I have an intuitive understanding of them as per your first definition. But how are they less intuitive when talking about time? I don’t get how this meme is structured
The definition part of the wikipedia article has a table with these “nice relationships for addition and scaling”. You will see that they also hold for many kinds of functions, such as polynomials and other more abstract things than points and directions in 2D or 3D. N-dimensional vectors for example, or using complex numbers, or both.
We can use vector spaces for thinking about things that aren’t primarily concerned with physical space like we are in Blender. Let’s imagine something practical, if a bit absurd. Pretend we have unlimited access to three kinds of dough. Each has flour, water, and yeast in different ratios. What we don’t have is access to the individual ingredients.
Suppose we want a fourth kind of dough which is a different ratio of the ingredients from the doughs we have. If the ratios of the ingredients of the three doughs we already have are unique, then we are in luck! We can make that dough we want by combining some amount of the three we have. In fact, we can make any kind of dough that is a combination of those three ingredients. In linear algebra, this is called linear independence.
Each dough is a vector, and each ingredient is a component. We have three equations (doughs) in three variables (ingredients).
This is a three dimensional vector space, which is easy to visualize. But there is no limit to how many dimensions you can have, or what they can represent. Some economic models use vectors with thousands of dimensions representing inputs and outputs of resources. Hopefully my explanation helps us see how vectors can sometimes be more difficult to imagine as directions and magnitudes.
It is just to consider polynomials and functions as vectors, and apply our meager intuition on 3d spaces. By introducing norms (size), you recover the “size and direction” analogy.
A vector space is a collection of vectors in which you can scale vectors and add vectors together such that the scaling and addition operations satisfy some nice relationships. The 2D and 3D vectors that we are used to are common examples. A less common example is polynomials. It’s hard to think of a polynomial as having a direction and a magnitude, but it’s easy to think of polynomials as elements of the vector space of polynomials.
Start with a list of numbers, like [1 2 3]. That’s it, a list of numbers. If you treat those numbers like they represent something though, and apply some rules to them, you can do math.
One way to consider them is as coordinates. If we had a 3-D coordinate grid, then [1 2 3] could be the point at x = 1, y = 2, and z = 3. You could also consider the list of numbers to be a line with an arrow at one end, starting from the point at [0 0 0] and stopping at the other point. This is a geometric vector: a thing with a direction and a magnitude. Still just a list of numbers though.
Now, what if you wanted to take that list and add another one, say [4 5 6], how might you do it? You could concatenate the lists, like [1 2 3 4 5 6] and that has meaning and utility in some cases. But most of the time, you’d like “adding vectors” to give you a result that maps to something geometric such as putting the lines with arrows end-to-end and seeing what new vector that is. You can do that by adding each element of the 2 vectors. And, almost magically, the point at [5 7 9] is where you’d end up if you first went to [1 2 3] and then traveled [4 5 6] further. We made no drawings, but the math modeled the situation well enough to give us an answer anyway.
Going further, maybe you want to multiply vectors, raise them to exponents, and more? There are several ways to do these, and each has different meanings when you think about them with shapes and geometry.
But vectors are just lists of numbers, they don’t have to be geometric things. [1 2 3] could also represent the coefficients of a function, say 0 = 1x^2 + 2x + 3(x^0). You can still do the same math to the vector, but now it means something else. It models a function, and combining it with other vectors let’s you combine and transform functions just like if they were lines and shapes.
When you get into vectors beyond 3 elements, there’s no longer a clean geometric metaphor to help you visualize. A vector with 100 elements can be used just as well as one with 2, but we can’t visualize a space with 100-dimensions. These are “vector spaces” and a vector is a single point (or rather, points to a point) within them.
Matrices are similar but allow for deeper models of more complex objects.
Very well explained, thank you. I keep forgetting, and am occasionally reminded, that just below the basic math I’m familiar with is a whole other level of advanced math, and just below that is the screaming void.
When talking about vector space, you usually need the “scalar (field)”, and scalars need inverse to be well-defined.
So for integers, the scalar should be integer itself. Sadly, inverse of integers stops being an integer, from where all sorts of number theoretic nightmare occursInstead, integers form a ring, and is a module over scalar of integers.
Honestly, given how annoying the alternatives are, I would say just buy a USB drive and put the bios file on there. You can get very good ones for under $20 and almost free ones if you don’t mind having an old tiny one.
This is the real answer. In this day and age where a 16gb USB stick can be had for literally $5usd on Amazon, it would be silly not to have a few kicking around. I don’t think any Linux distro live environment media requires more than 16gb, and it’s more than enough for updating a bios. I even used one to update the infotainment system in my vehicle last week. Kind of a necessary tool.
Even if you need one immediately and can’t wait on Amazon, it’s back to school season. They are plentiful everywhere. Target, Walmart, Kroger, Staples, Office Depot, etc. etc. etc.
Yes, however, it’s the other chemicals they mix it with that make it not biodegradable. Thankfully there are some companies not using those chemicals now which is lovely.
Also, for those who are allergic to latex, unfortunatley the only option is polyurethene which is plastic, and as such not at all biodegradable.
I do this as well and for the most part it’s been fine. It’s handy to have options and, even for apps that do run under Windows, it’s often less hassle to just fire up the VM.
Using binary with bent/straight fingers gets you up to 31. There are other ways - like touching your thumb to different phalanges of different fingers, for 0…12.
Bend them the other way. Start with all fingers open for zero, and curl them as needed. You only need to move them a bit, so even twenty (thumb and ring finger back, the others curled) isn’t too hard.
you can cheat it quite easily, just hover your hand over a table or surface, and touch your fingers to the surface to indicate a 1, and dont to indicate a zero, works on your leg, or someone elses, if you felt like it i guess.
great point… and if after the 12 you start touching your thumb to the other side of those phalanges, you now have 24. now each time you go through the 24 cycle, your other hand can tick along the same cycle like an hour hand. now you are counting to 550+ with 2 hands.
I was able to get to this number: 1 048 576 by using base 4 and making each finger a different “10” s place using each finger segment and the tip of the palm below it but you have to keep track of how many of each order of magnitude you have by yourself. Alternatively, just use a piece of paper.
