Can I still update apks currently on my android device with an apk updater app if I uninstall the package installer?

If I were to find a way to disable install via ADB, install an APK updater app that auto updates apps and then uninstall the package installer, would the apk updater still be able to update apps already on the device without the package installer, but the user wouldn’t be able to install new apps if no other installers had root permission? If not, how can I achieve this without installing any parental control apps or monthly subscriptions? Link to previous question for reference purposes here

How can I create the large disks in Azure that are currently in public preview?

Azure started supporting extra large disk sizes in September 2018 (as described here) as a public preview, currently available only in the West Central US region.

I’m trying to create a new S60 (4-8 TiB HDD) disk in a resource group located in the above region. However the disk creation dialog still limits me to up to 4095 GiB disk size. It even tells me that larger sizes are currently in public preview.

How can I actually create the disks described in the preview?

Can’t install the software because it is not currently available from the software update server – iPad

I’m attempting to sync my iPad with my MacBook pro, but every time I plug it in I’m getting a message from iTunes, “A software update is required to connect to your iOS device.” When I click “Install,” I get another error message: “Can’t install the software because it is not currently available from the software update server.” The iPad’s charging icon is also blinking off and on.

As I’ve been poking around the internet about this, I’ve gotten several answers about how this is something to do with a beta version of iOS, however currently running only the most current and stable builds of iOS and macOS (iOS 12.1.1 and macOS 10.14.2). Apparently installing xCode worked for some folks back in July/August, but I’ve done that to no avail…see this thread with the same problem, and a user offering the xCode solution: A software update is required to connect to your iOS device / iPhone

Any help is much appreciated!

Is it possible to layer an API (REST, GraphQL, etc.) in front of data that is currently only accessible via an enterprise desktop GUI?

Currently, my thoughts are that GET requests would be feasible by using the concept of screen scraping combined with a cron job that runs at a set interval to scrape data from the GUI and sync to my own database.

However, I’m not quite sure how I would handle actions that seek to mutate the database that sits behind the GUI. I am quite certain I would need to interface directly with the GUI, but what tools are available that could help automate this by programmatically controlling the GUI?

Also, since an overall architecture such as this is far from conventional, I’m curios what strategies might be utilized to help scale a system such as this.

Note: It is acceptable for data returned from a GET request to be stale for at least as long is the cron job interval, and for POSTs and PUTs and the like to complete sometime in the future, let’s say half an hour.

Note: Maybe my train of thought is completely idiotic and there’s a better angle. I’d love to know.

Nginx Sorry, the page you are looking for is currently unavailable. Please try again later. | Checked lots of other posts no luck

I have a nginx server (1.10) and I am trying to access a certain location block for letsecnrypt but having no luck. I have modsecurity and pagespeed both included in my compiled nginx.

OS is Ubuntu 16.04 LTS

My error message I get is `An error occurred. Sorry, the page you are looking for is currently unavailable. Please try again later.  If you are the system administrator of this resource then you should check the error log for details.  Faithfully yours, nginx. 

Here is my nginx location block:

location ~* /\.well-known {   root /work-disk/www;   try_files $  uri $  uri/ @other_node; #@other_node is another location block to handle passing requests to my second server that I can no remove   # access_log off;   pagespeed off;   ModSecurityEnabled off; } 

I have so far checked /var/log/nginx/error.log and /var/log/messages both of which show nothing pointing to anything. The former shows logs about the process and the latter shows a blank fine

Is there any solution that currently exists for the graph automorphism problem in the general case?

I was reading the Wikipedia pages on the graph automorphism, but I could not find any solution to the problem (Not even a brute force one). So, is it indeed true that no solutions exist for the general case of the automorphism problem?

P.S. Are there any significant uses of a solution to this problem in pure mathematics, or is the significance of such a solution mostly practical?

Thank you in advance.
