Which is faster '1GB RAM with 64 bit' or '2GB RAM with 32 bit' I planed to purchase new mobile. I confused with processor and RAM.    Quad-core 1.2 GHz Cortex-A53 (64 Bit) 1GB RAM Quad-core 1.6 GHz Cortex-A7 (32 Bit) 2GB RAM   Which one will be faster?
How do RAM and processor speed affect overall performance on Android? Since Android can be installed on wide range of devices, I'm wondering how important RAM and the CPU speed are to the performance of a device.  There are always tradeoffs when something is increased and another one decreased!  Is more RAM or a faster processor better for general browsing and less mulititasking?  What if I'm interested in gaming or doing lots of things at once?  Will more RAM make up for a slower processor or vice-versa?
How much of 32-bit support is dropped in macOS Catalina? macOS Catalina is said to have dropped support for 32-bit apps. It’s not clear how much support is dropped.   Is there any supported way for a 64-bit app to request the kernel to create a 32-bit code segment? Is division of matrices possible? Is it possible to divide a matrix by another? If yes, What will be the result of $\dfrac AB$ if $$         A = \begin{pmatrix}         a &amp; b \\         c &amp; d \\         \end{pmatrix},         B = \begin{pmatrix}         w &amp; x \\         y &amp; z \\         \end{pmatrix}? $$ Objects Not Showing in Other Workspace Viewports, Only Default If a function $f : \mathbb Z\times \mathbb Z \rightarrow \mathbb{R}^{+} $ satisfies the following condition  $$\forall x, y \in \mathbb{Z}, f(x,y) = \dfrac{f(x + 1, y)+f(x, y + 1) + f(x - 1, y) +f(x, y - 1)}{4}$$  then is $f$ constant function? If I run history, I can see my latest executed commands.  But if I do tail -f $HISTFILE or tail -f ~/.bash_history, they do not get listed.  Does the file get locked, is there a temporary location or something similar? Why do I keep getting told I posted less than 15 characters when I posted more than 15? I tried to post the following comment and it claims it was less than 15 when it was more.  Based on Tim's comment and testing I believe it would not let me post because with @Shadow removed it is less than 15. However, the characters left message indicates I have passed the 15 character minimum thus it is wrong.  This is the bug I'm reporting:  The characters remaining message and the characters left message do not take into account striping out @name prefixes. How do I build a house for my NPCs? I read on the wiki that people will move in under the following conditions:   You do something to please them An empty house is available with a light source, table, and chair (also with walls).   I have a house which is about 7x8, then a roof space above that; about half the area. I could put furniture up there too, but will anyone move in? How do I get a list of installed files from a package? How to replace text between quotation marks with something from another file? I have the following kind of text: $OU = 'or'; $DINHEIRO_CAIXA = 'Cash balance'; $PAGINA = 'Page'; $DE = 'from'; $ENVIAR = 'Send'; $PRINCIPAL = 'Main';  I've already got all the text within the single quotation marks using cat arquivo | grep -oP &quot;'[^']+'&quot; | tr -d &quot;'&quot; This extracted text was then translated to Portuguese, but now I don't know how to replace the original text between single quotation marks with the translated text, I was looking for something like $OU = 'ou'; $DINHEIRO_CAIXA = 'Dinheiro em caixa'; $PAGINA = 'Pagina'; $DE = 'de'; $ENVIAR = 'enviar'; $PRINCIPAL = 'Principal';  I've tried using grep -F to replace the file itself, but it failed miserably because the pattern didn't match since I don't have the quotation marks on the new file, is there a way to do this? I need an approach to allow delegated admins (i.e., non-Administators) to add members to Public Groups and Collaboration Groups (the GroupMember and CollaborationGroupMember objects).  I added a custom object (UserGroupRequest__c) to capture which Users should be added/removed to which Groups.    I've also built a batchable class to process the requests.  However, GroupMember is a Setup object, and CollaborationGroupMember is not.  So this doesn't work if I combine the operations in a single batchable class.  Should I instead be using 2 batch classes, calling one from the finish method of the other?    Any recommendations on how best to proceed?  Am I way off base?    Would a trigger on the Request object perhaps be better? I'm guessing that there may be a permission problem if this is attempted via a trigger as the delegated admins won't be able to add users to public Groups.  Also, I'm guessing the trigger approach would run into the same mixed DML issue - on Insert of the Custom object, I would need to Insert/Delete from GroupMember and from CollaborationGroupMember, and then perform a 2nd update on the Custom object to indicate that processing was completed... Show that a matrix $A$ is singular if and only if $0$ is an eigenvalue. I can't find the missing link between singularity and zero eigenvalues as is stated in the following proposition:  A matrix $A$ is singular if and only if $0$ is an eigenvalue.  Could anyone shed some light? Do the SSH or FTP protocols tell the server to which domain I am trying to connect? When using the ssh or ftp commands from the Bash shell, does the server that I am connecting to learn of the domain name used? I understand that the domain name is locally translated into an IP address via DNS. In HTTP, after that happens, the server is told the original domain name as well in order to serve the correct page, or to present the correct TLS cert (SNI).  host serverfault.com GET /   Does a similar phenomenon happen when connecting to ssh or ftp?  I ask because I am  trying to ssh into a server (GoDaddy webhosting) which expects a domain name, but is not letting me in when I try to connect via user@IPaddress as the DNS is not yet moved to the GoDaddy IP address. Since arrays and hashes can only contain scalars in Perl, why do you have to use the $ to tell the interpreter that the value is a scalar when accessing array or hash elements? In other words, assuming you have an array @myarray and a hash %myhash, why do you need to do:  $x = $myarray[1]; $y = $myhash{'foo'};   instead of just doing :  $x = myarray[1]; $y = myhash{'foo'};   Why are the above ambiguous?   Wouldn't it be illegal Perl code if it was anything but a $ in that place? For example, aren't all of the following illegal in Perl?  @var[0]; @var{'key'}; %var[0]; %var{'key'}; I recently got a new router, a DRL-600L Router from D-Link, and was setting up some filters to block out certain websites.  One problem I am having is blocking out addresses that use https instead of http.  For example, I'm trying to block out Facebook, because Facebook.   So far, the filter filters http://www.facebook.com perfectly fine, but for the url https://www.facebook.com, it won't block that.  How can I block those kinds of websites? Access pictures from Pictures app in my android app Just like the iPhone has a UIImagePickerController to let the user access pictures stored on the device, do we have a similar control in the Android SDK?  Thanks. My initial problem was that my computer wouldn't let me login to my account. It seems to shut down after I enter my password. I can login as a guest.  I found fixes but I can't remember / figure out my login for access after I hit Ctrl+Alt+F1 and most of the fixes for finding your login username depend on you having access to your account.  I thought the login was the name which appears on the screen when I start the computer normally, but this has not worked, is there another way to find out my username while being effectively locked out of my root-user profile?  I am also assuming that the password is the same one I always use.  Conversely, if the name which appears on the screen at startup and my normal password should have worked, is there another explanation for why I am not able to login on the black command screen. What is data blending? This term appears frequently in the .  Is blending a specific method in data-mining and statistical learning? I cannot get a relevant result from google.  It seems blending is mixing up outcomes from many models and resulting in a better result. Is there any resource that helps me knowing more about it? How can I test the fairness of a d20? Using \vfill between two texts works:  \newpage bla \vfill blabla   but it doesn't work if there is no text before it:  \newpage \vfill blabla   How can this be achieved? CSS 100% height with padding/margin With HTML/CSS, how can I make an element that has a width and/or height that is 100% of it's parent element and still has proper padding or margins?  By "proper" I mean that if my parent element is 200px tall and I specify height = 100% with padding = 5px I would expect that I should get a 190px high element with border = 5px on all sides, nicely centered in the parent element.  Now, I know that that's not how the standard box model specifies it should work (although I'd like to know why, exactly...), so the obvious answer doesn't work:  #myDiv {     width: 100%     height: 100%;     padding: 5px; }   But it would seem to me that there must be SOME way of reliably producing this effect for a parent of arbitrary size. Does anyone know of a way of accomplishing this (seemingly simple) task?  Oh, and for the record I'm not terribly interested in IE compatibility so that should (hopefully) make things a bit easier.   EDIT: Since an example was asked for, here's the simplest one I can think of:  &lt;html style="height: 100%"&gt;     &lt;body style="height: 100%"&gt;         &lt;div style="background-color: black; height: 100%; padding: 25px"&gt;&lt;/div&gt;     &lt;/body&gt; &lt;/html&gt;   The challenge is then to get the black box to show up with a 25 pixel padding on all edges without the page growing big enough to require scrollbars.
