My Tecno pop 2 does not have the notifcation access feature. It always shows me that that feature is not available on my device. I tried to correct it by going to the special advanced settings but I do not have a notification access option. What do I do?
I have a TECNO Spark 2 running on Android 8.1 Oreo (Go Edition). Every time I try to install apps that require notification access, it says that the feature is not available.  How to fix it?
Actual memory usage of a process The following are the memory usage of mysql and apache respectively on my server. As per the output of pmap say, mysql is using about 379M and apache is using 277M.   [root@server ~]# pmap 10436 | grep total  total           379564K  [root@server ~]# pmap 10515 | grep total  total           277588K   Comparing this with the output of top, I see the values are almost matching.    PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND 10515 apache    20   0  271m  32m 3132 S  0.0  6.6   0:00.73 /usr/sbin/httpd 10436 mysql     20   0  370m  21m 6188 S  0.0  4.3   0:06.07 /usr/libexec/mysqld --basedir=....   Now these values definitely are not the current memory usage of those two processes, since if it were it would've exceeded the 512M ram on my system and I understand the fact that these are the size of the pages assigned to these two processes and not really the size of the memory actively used by them. Now, when we use pmap -x, I see an extra coloumn Dirty which shows far less memory usage for the process. As seen in the example show below, the Dirty coloumn shows 15M as opposed to 379M in the first coloumn. My question is: Is the value under coloumn Dirty is the 'real' amount of memory actively used by that process? If its not, then how can we find out the real memory usage of a process? Not ps and top for the same reasons above. Do we have anything under /proc that will give this info?

It gives three descriptions of real n-dimensional  projective space $P^n$. Two of them are:  (a) Begin with the unit sphere $S^n$ in $E^{n+1}$ and identify its antipodal points.  (c) Begin with the unit ball $B^n$ and identify antipodal points of its boundary sphere.  I find it hard to imagine why these two descriptions lead to the same space.  Can you please help? Thank you. Prevent Adobe Reader from switching to "Fit Page" zoom when bookmark is clicked How to show $\sum_{i=1}^{n} \binom{i}{2}=\binom{n+1}{3}$? Show that $\,\displaystyle\sum_{i=1}^{n} \binom{i}{2}=\binom{n+1}{3}$.   I'm thinking right now (though not getting anywhere with it) that I want to expand out the summation portion to $i!/2!(i-2)!$ and simplify from there? Not sure if that will help, not to mention if I put $1$ in for $i$ I get $1/-2$ which I don't think is right.   Anyone care to shed some light on the subject?   Thanks.

Can a curve object modifier created geometry be used as boolean factor This question is related to .  Let me use an exemple to illustrate what I mean.  We've created a text object (made of curves). It can't be used in a boolean modifier as it won't appear in the list of usable objects in the modifier because it's a curve object.  But if we add a remesh modifier on the text, geometry is created from the shape.  The object could be used as boolean if we convert it to mesh. The remesh can't be applied on curve object.  My question is : Can we dynamicaly use the remesh modifier created geometry as real geometry or make the boolean modifier consider the text modified object as a real mesh?  The idea behind this is to be able to change the text (or any curve 3D shape) without having to make it a real mesh.  (don't hesitate to edit my poor english to make it understandable :) ) Can I run Android apps on Ubuntu? Is it possible to run Android apps on Ubuntu?

When a partial differential equation is solved using the separation of variables method, is the produced solution the most general one that satisfies the equation or have we lost some forms of the solution because of the assumption that it is in the form of separated variables? Stop jQuery .load response from being cached I have the following code making a GET request on a URL:  $('#searchButton').click(function() {     $('#inquiry').load('/portal/?f=searchBilling&amp;pid=' + $('#query').val());             });   But the returned result is not always reflected. For example, I made a change in the response that spit out a stack trace but the stack trace did not appear when I clicked on the search button. I looked at the underlying PHP code that controls the ajax response and it had the correct code and visiting the page directly showed the correct result but the output returned by .load was old.  If I close the browser and reopen it it works once and then starts to return the stale information. Can I control this by jQuery or do I need to have my PHP script output headers to control caching? I came to know about , it's a website that allow search for flights by country. I mean you just enter from like "Germany" and to like "Belgium" and you get best offers from all airports between the two countries. That is great. And I was able to arrange a good-price trip to Brussels.   Now I want to arrange another trip to Turkey, but Whichbudget is not helping much this time. And I can't find any other websites that allow "search by country".   Update: Not duplicate to  as his question is broad to the extent of a state. But my question is broad to the extent of a whole country + less price + "Any Time". If anyone checks , he'll understand what I'm saying. Especially that whichbudget allows "Any Time" option, not just +/-3 days.  Does anyone know more similar websites? I created a interior scene and  i don't know how to bake a texture using cycles bake. get_post_gallery with Gutenberg I have a site where I created a page that takes the gallery images from a post and puts them into a slider.   I used the following code:  // gets the gallery info $gallery = get_post_gallery( $post-&gt;ID, false ); // makes an array of image ids $ids = explode ( ",", $gallery['ids'] );   Then I inserted the images using wp_get_attachment_image().   Unfortunately, with WP 5.0 and Gutenberg, get_post_gallery no longer works with newly added content. It seems that get_post_gallery used a shortcode that no longer works with Gutenberg.   I am still getting up to speed on Gutenberg and the block system. Until I understand that all better, I was wondering if anyone has any advice on how to get the image ids from a gallery in Gutenberg? Over at , there is overlapping text in the Database Schema under Close-As-Off-Topic-Reason-Types:  that makes it really hard to read.  This is also happening underneath &quot;Pending Flags&quot;, and seemingly with every long line in the schema.  This would be fine if you could increase the width of the list as you can with the height, which would in theory separate the lines, but you can't.  Can we fix this, please?  UPDATE: I have found that  post is almost exactly the same as mine, but steady on with duplicate votes.   comment says that it will be fixed, but that question was asked more than five years ago, and in that time the problem has not been resolved.  UPDATE 2: It seems that  would help.  I changed a little CSS/HTML, and came up with this:  Although mine is a little cruder than it could be.  This is just an example. I read following in a web site ()     Lenses with maximum apertures of f2.8 allow the camera to use all high   precision sensors. In low light or other situations that are hostile   to autofocus, that’s a big deal. Lenses with a maximum aperture of   f4.0 use only the center focus sensor in its “high precision” mode,   and use the other sensors in their “horizontal line” only mode. Lenses   with a maximum aperture of f5.6 use all sensors in their   “horizontal-only” mode, and lenses with a maximum aperture of f8 use   only the center sensor point, and that with horizontal sensitivity   only.   I want to understand if this is completely true? I am raising this because recently I have purchased a Nikon 70-200 f/4 lens and would like to understand if I have made a wise investment, or, should I collect some more money and buy a 70-200 f/2.8 VR-II lens. How to format/partition SD card? How can I format or partition SD card in Kubuntu?  Is there an application with GUI for this? I have two raster files that are the same cell size but I cannot get them to align properly. (I want the black to line up with the pink)    When creating the black raster file (from using polyline to raster), I imported the pink raster in the Snap Raster section in the Environments setting. I thought that Snap Raster was supposed to make it line up?  Am I doing something wrong or is it a bug in Arc (I remember reading that this was a problem about two years ago), and if it is a bug is there a work around?  I have also read there is a Raster Shift, but I'm not sure what to enter in the X Coordinate and Y Coordinate. Since I only want the black raster to shift down, I know that the X Coor = 0 and the Y Coor should be negative something, but what are the units?  Thanks. Can I find out which tags I have created? This would be interesting to know.  The tags could be highlighted on the users page for example. Old title - "change resolution to 1280x1024 using xrandr gives: X Error of failed request: BadValue (integer parameter out of range for operation)"  I have installed a fresh Ubuntu 17.10 and have a monitor with 5:4 resolution. settings has no resolution higher than 1024x768. But I need the resolution 1280x1024 (5:4).  I use the default motherboard graphics card:  # lspci|grep VGA 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)   Also xrandr gives the following:  $ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 XWAYLAND0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm    1024x768      59.92*+   I tried to add the 1280x1024 resolution using xrandr. so first created the resolution information using gtf:  $ gtf 1280 1024 60    # 1280x1024 @ 60.00 Hz (GTF) hsync: 63.60 kHz; pclk: 108.88 MHz   Modeline "1280x1024_60.00"  108.88  1280 1360 1496 1712  1024 1025 1028 1060  -HSync +Vsync   Then added to resolutions:  xrandr --newmode "1280x1024_60.00"  108.88  1280 1360 1496 1712  1024 1025 1028 1060  -HSync +Vsync   then again did the command: xrandr --addmode XWAYLAND0 1280x1024_60.00  Then nothing changed. When I tried to change it using xrandr --output XWAYLAND0 --mode 1280x1024_60.00 --rate 60 But an error occurred:  $ xrandr --output XWAYLAND0 --mode 1280x1024  --rate 60 X Error of failed request:  BadValue (integer parameter out of range for operation)   Major opcode of failed request:  140 (RANDR)   Minor opcode of failed request:  7 (RRSetScreenSize)   Value in failed request:  0x0   Serial number of failed request:  21   Current serial number in output stream:  22   I don't know what did I do wrong.
