How can I save my hardcore map after I die? My brother jumped into the voice of the doom in my Hardcore Creative map. I didn't press the ΄΄Delete This World΄΄ button yet. Derivation of the Partial Derangement (Rencontres numbers) formula I'm looking for the method by which the partial derangement formula $D_{n,k}$ was derived. I can determine the values for small values of N empirically, but how the general case formula arose still alludes me.  Any links/books or an explanation will be appreciated.  The formula is:  $D_{n,k} = {n \choose k}!(n-k)$  Links: Undo a particular commit in Git that's been pushed to remote repos Calculate Euler equations of fluid dynamics without division? I would like to know if the same Minecraft account used on a computer can be used on a different platform like the Xbox 360?

Basically I would like to know if all the saved stuff and settings from one platform will carry over to another. How to measure the component value on a PCB? Is it worth it to upgrade a Toshiba Satellite C55-A5300 laptop given the latest productivity software requirements? I would like to upgrade a Toshiba Satellite C55-A5300 laptop so it can be as useful as it can be nowadays. I haven’t needed to use much software for a few years now, and I’m not able to gauge whether a maxed out upgrade of this laptop would be up to running the latest versions of MS Office and Acrobat smoothly. Maybe even run some Photoshop and Lightroom? I want to install the best CPU that will work optimally within the parameters of this laptop, including the laptop’s cooling capabilities. I ultimately want improved performance, but I want the performance to be as smooth as possible. From what I gather the Pentium 2030M is the best processor this motherboard will accept. Am I on the right track? I also plan to fully upgrade the memory and the hard disk speed with respective upgrades. What is the max memory per RAM slot (2 total)? What is the fastest speed of RAM I can use?

To polish my skills I start learning Drupal 7. While learning Drupal architecture concepts, the terms hooks and bootstrapping puzzled me a lot. I read the "Pro Drupal development" book, and some documentation on drupal.org, but it is so advanced for me to learn how hooks work in Drupal to display the web page.  Can anyone tell me what hooks are in simple words? NetGear A6100 AC600 wireless adapter not working in Ubuntu 20.04. Worked fine in 18.04. Not same problem as previously Firstly, I know very well there are answers to this already. But, in my case, it is installed and shows in the terminal as such Bus 001 Device 007: ID 0846:9052 NetGear, Inc.

Whilst it is obvious I could set up tables or use mathmode's align feature, it seems so much more efficient to have a package handle the tabbing automatically, since it is rather predictable in this application.  mhchem does not seem to have such a feature...      Another advantage is you could maintain the readability of your equations and you would not have the added clutter associated with tables, especially tabs &amp;, which diminish the readability of your .tex document.  And of course, the line should be automatically inserted before the last row. How to write uncertainties with the \pm symbol "10 ± 1 K" by using siunitx? Using the siunitx package, if I specify an error with the \pm symbol then it automatically converts it to a form using parenthesis. I would like it to not do this and keep the \pm symbol, but still space the elements of the quantity and symbol in a good way.  e.g. \SI{10 \pm 2}{\kelvin} would produce 10(1) K  I would like it to produce: 10\pm1 K or something similar with spacing taken care of. Search for singleton tags on questions How to install Windows 7 from the network? Is it possible to install Windows 7 (Current RTM Version) on a computer without using removable media like DVD or USB?  The first thing that comes to my mind is through the network, but I don't have experience of doing a fresh install of Windows 7 via the network.  How to install Windows 7 via the network without any removable media?  P.S. I know some may think that doing so, is just a waste of time and it's easier to do it with removable media, but in the current situation the target PC neither has CD/DVD Drive nor supports booting from USB. And in addition to that, the target computer is connected to the network via a wireless connection (I don't know if it will cause any problems with the installation). If I multiclass into 2 or more spellcasting classes, how do I determine my known/prepared spells? If I multiclass into 2 or more classes/subclasses that can cast spells, how do I determine what spells I know or can prepare?  For instance, if I am playing a multiclassed character with 1 level in warlock, 2 levels in bard, and 3 levels in paladin, how do I determine which spells I know/have prepared?    Related: I found Minecraft's marvelous large worlds extremely slow to navigate, even with a quad core and meaty graphics card.  I assume Minecraft's slowness comes from:   Java, as spatial partitioning and memory management are faster in native C++. Weak world partitioning.   I could be wrong on both assumptions. However, this got me thinking about the best way to manage large voxel worlds. As it is a true 3D world, where a block can exist in any part of the world, it is basically a big 3D array [x][y][z], where each block in the world has a type (i.e BlockType.Empty = 0, BlockType.Dirt = 1, etc.)  I assume that to make this sort of world perform well, you would need to:   Use a tree of some variety (//) to split all the cubes out; it seems like an oct/kd would be the better option, as you can just partition on a per cube level not a per triangle level. Use some algorithm to work out which blocks can currently be seen, as blocks closer to the user could obfuscate the blocks behind, making it pointless to render them. Keep the block object themselves lightweight, so it is quick to add and remove them from the trees.   I guess there is no right answer to this, but I would be interested to see peoples' opinions on the subject.  How would you improve performance in a large voxel-based world?

Link is probably broken If link isn't broken, it's spam If link isn't spam, it's to some broadly-related resource that the answerer found by pressing &quot;I'm feeling lucky&quot; when googling the question's title.  ...but the real issue here is that we don't know! Even if the link was originally pointing directly to the most awesomeest answer ever for exactly the question being asked, there's nothing in the answer itself to even hint at what direction we're being pointed in.

No. Even the title of the page being linked to would have provided something to go on, but that was entirely too much work. So let me be clear: this sort of response is not an answer. If you see this, flag it. Moderators, if you see it flagged, delete it. There's really only one valid exception to this rule, and that's when the question is:  Suggest me some tutorials where i can learn quick.  Don't get me wrong, it's still a bad answer - but when the question is kinda asking for bad answers this is to be expected.
