## Highlights connected to comments dissappeared

I have someone reviewing a document for me in Google Docs. All of a sudden her comments are there on the right, but the highlight over the text associated with that comment is gone. In other words, I can read her comment but I have no idea which portion of text she is talking about because the highlight is gone. Can someone help? How do I get the highlights back?

## When no sound comes out of wired headphones connected to “USB to headphone adapter”, how do you get the sound to work?

background:

• I have a new phone, Google Pixel 2, that does not have a 3.5 mm headphone jack
• about 4 times out of 5 times when I try to use wired headphones –> the sound does not come out of the headphones but instead is emitted from the phone’s speakers

things i’ve tried:

• I have tried unplugging and plugging in the “USB-C to 3.5 mm headphone adapter” (or just “USB to headphone adapter” for short) and sometimes this gets the audio to come out of the headphones.
• But many times no matter how many times (10+ times) I try unplugging/plugging the “USB to headphone adapter” into the phone… the audio does not come out of the headphones.

When no sound comes out of wired headphones connected to “USB to headphone adapter”, how do you get the sound to work?

## Apache h2_filter OS 10060 A connection attempt failed because the connected party did not properly respond after a period of time

I’ve been trying to figure this out all day and have exhausted myself..

Scenario:

• OS Windows 10
• Apache 2.4
• PHP 7.3 TS
• OpenSSL

Symptoms:

Web applications sporadically take an abnormal amount of time to load, out of memory errors, Apache restarting.

Problem:

Whilst attempting to load (over SSL) a simple PHP file, that contains nothing but `"Hello World!"`, I get the following in debug error logs:

I am a bit of a novice when it comes to understanding these “errors”, and please correct me if I am wrong, but it seems to me that all is OK, until I get to:

There appears to be some repetitive attempts, before a 30 second delay until the connection is closed or an unknown error.

I am not certain whether it is a problem with `h2_session` or `h2_filter`. nor do I know what the `resuming Invalid argument` error relates to.

I’ve searched the pants off this, but the only thing that comes close related to proxy settings. And although I have the proxy modules loaded, I don’t have any virtual sites using them.

I have checked the full debug errors and I am not getting anything related to SSL.

Does anyone have any idea as to what I should be looking for?

Cheers

## What happens to connected clients when Apache 2 is stopped?

I have a legacy Apache HTTPD 2 server running in MPM prefork mode. A mis-configuration left us in a situation where the `MaxRequestWorkers` setting was too low, causing client requests to queue waiting for a child process to service their request.

During this scenario, an `apache2ctl -k restart` command was issued, stopping all the child processes and restarting the daemon.

I cannot find any indication in the Apache documentation as to the effects this would have on:

• Client connections currently being serviced by a child process
• Client connections queued awaiting a child process.

My assumption is that a TCP-level disconnection would occur, but would be grateful if anyone could confirm, or describe the behaviour if otherwise.

## What can be done before Content Database is connected?

Soon we’ll be grading our SharePoint environment in an overnight upgrade… I’m currently prepping our servers to make the transition as painless as possible, but what sort of configuration can be completed prior to importing the content database? Currently we’ve only got the default `SharePoint_Config` database for Central Admin ready.

The things I’ve got left that I’m not sure on are:

• Configuring Service Applications / services on the servers
• Configuring outbound email
• Add other general applications (ie SPD, Infopath, etc)

## Alternatives to directly connected networks for representing frequently-updated graphs

What are the relative merits of the various graph representations, such as adjacency matrix, edge list, adjacency list, directly connected network etc. Given that this graph will be frequently updated, split, joined to other graphs?

Business Context: I am writing a molecule editor in C# and have currently used a directly connected network, although this has proven to present problems when updating. I am looking for a better way of doing this.

## How to get location as soon as FusedLocationApi connected?

I use the following codes to get the location of user using FusedLocationApi however it seems that onLocationChanged really works when the location is really changed but not sends the initial location. When I start the Api nothing happens but when I change my location the target function is called.

This is how I start the Api:

``   @Override     public void onConnected(Bundle dataBundle) {        LocationServices.FusedLocationApi.requestLocationUpdates(mLocationClient, mLocationRequest, this);     } ``

And this is how I call my own function:

``@Override public void onLocationChanged(Location location) {     if (location != null) {         CurrentLocation=String.valueOf(location.getLatitude())+"_"+String.valueOf(location.getLongitude());         SenDataToServer();     } } ``

How can I get the location as soon as `onConnected` is fired not on location changes. Thanks

## Counting the number of undirected simple and connected graphs

I would like to count the number of undirected simple and connected graphs with $$2k$$ different vertex so there is a an one and only edge that if will remove it, the graph will be build of two disconnected graphs $$G_1,G_2$$ so they are both complete graphs?

How can I approach this issue?

## How to display a connected boxes with inputs and outputs in a smartphone?

Imagine the concept of a black box, that can have inputs and outputs.

A box can connect with other boxes. We have something like this:

Now imagine a smartphone. “Ok, this guy is crazy.” You thought. And you are right.

I am having several problems conceiving an alternative representation for this kind of structures in a smartphone.

Let me give a concrete example:

As you can see we have two boxes from the same type that provide each one a number. Those 2 numbers go into a box that sums and produces the sum. That sum is connected to a box that displays the number received.

There are two important types of boxes: Information providers and actions. Information providers usually start these diagrams and actions generally finish them.

It is important to know what type of block is being used and how blocks connect with each other. Another relevant fact is that new type of blocks can be created. Therefore, this structure is flexible and expansible.

EDIT:

Although I didn’t come to a solution yet one thing I know for sure:

I need a system that allows the user to simplify the scene, grouping blocks. Still I have the problem on how to represent this. Is all information important?

Please be aware that I belive the user needs to see the “full picture” or at least what matters of that picture. The minimum I belive that is important is:

• Know what is connected to what
• What provides info and what is the final result
• How the information flows between the boxes.
