I am having problems restarting the emulator after turning it off. Restarting android studio - doesn't help. Restarting my computer helps. I also cannot find and [stop this process] through the task manager. So that I can not reboot. By the way, the error is displayed with a typo. Help. Who faced such a problem, how to solve it?
...ANSWER
Answered 2021-Jun-15 at 14:21On Windows, the software that runs the Android Emulator is called "qemu-system-x86_64.exe".
Try to kill this software. You can use the built-in taskkill
utility from within the Command Prompt:
- Open the Command Prompt (Type in CMD into the Windows search)
- Enter:
taskkill /F /IM "qemu-system-x86_64.exe" /T

QUESTION
I am modeling a Time-constrained CVRP. The problem is to minimize the total travel time (not including the package dropping time) subject to vehicle (delivery) capacity and total time spent (per vehicle) constraints. The package dropping time refers to an additional time to be spent at each node, and the total time spent equals to the travel time plus this additional time. I have the below model that works for a single vehicle-type case. I would like to introduce two-vehicle type concept in there, meaning that I have a set of V1
type vehicles and another set of V2
type vehicles. The only difference of the vehicle-types is the per time cost of travel. Let x
denote the per time unit cost of travel by V1
, and y
denote the per time unit travel cost of V2
. How can I design the model so that it incorporates this additional aspect?
ANSWER
Answered 2021-Jun-13 at 13:34Simply register two transits callbacks (i.e. one per vehicle type)
Then use the overload of AddDimension() to pass an array of registered transit callback index.

Currently all rectangles will be draw on screen! I try to use exit pattern but not work!

Answered 2021-Jun-15 at 03:42There appear to be two key issues:
Enter/Update/Exit
The exit selection only contains elements when there are selected elements in the DOM which do not have corresponding items in the data array. In your case we have an empty selection with bound data:

I know there are some other questions (with answers) to this topic. But no of these was helpful for me.

...ANSWER
Answered 2021-Jun-15 at 08:30Here I'm wondering about the line [in s_client]
New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384
You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:
QUESTION
I have problem with my bpf program. I getting error while loading this program. my bpf program is:
...ANSWER
Answered 2021-Jun-15 at 07:28TL;DR. You should check that the pointer returned by bpf_map_lookup_elem
is not NULL.
With the following logs, the BPF verifier is telling you that, when it reaches the dereference of my_pid
, the pointer may still have a NULL value. It thus contains a map value or a NULL value, i.e., map_value_or_null
.

QUESTION
I got an order from school so I've tried to make them. This is my code:
...ANSWER
Answered 2021-Jun-14 at 15:11Your code has an error in it, which is the use of break
statements within the if
and else
clauses. If you remove the break
s, it should work.
break
statements can only be used within for
/while
loops and switch
statements. You can't use them (and don't need them) in if
/else
statements.
If you click "run code snippet" on your example, it shows the error message Uncaught SyntaxError: Illegal break statement
which would help you find this issue. Also, if you open your browser's JavaScript console, you should find this error message where you are running your code. This will help you find and fix errors in the future.
