kandi X-RAY | 2048 Summary
A C++/Qt clone of the popular 2048 game. Game logic is written in C++, the GUI in Qt 5.2.1. The entire GUI is written in code, Qt Creator’s UI designer was not used. The core is decoupled from the GUI using the observer pattern, so it is easy to pull the code, extract the core and then build a new GUI around it. Alternatively, if you want to build outside of Qt Creator, this is possible as long as your system has both qmake and make. In that case, just run qmake && make in the checked out repository.

QUESTION
I know there are some other questions (with answers) to this topic. But no of these was helpful for me.
I have a postfix server (postfix 3.4.14 on debian 10) with following configuration (only the interesting section):
...ANSWER

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 am able to do most things inside the dir, but I can't cd out of it, trying /bin/sh causes the shell to freeze.
...ANSWER
Answered 2021-Jun-14 at 22:06Because everytime you send a command a new shell is created in the original folder.
To set an other working directory you have to send cd /to/other/dir && yourcommand
You can try setting the root folder for the new shell terminal:
QUESTION
I am running a Java based application and it is crashing due to Insufficient memory. Some output snippet of hs_err :
...ANSWER
Answered 2021-Mar-04 at 01:48You've used -Xms to force the JVM to get ~30GB at JVM startup.
It has tried, and failed. It only obtained 8GB. It needs another 22-ish GB but cannot get it. That is what the error message is telling you. This is consistent with a dump that says the heap is only 8GB.
You're asking for more than the OS will provide. You'll need to figure out what's going on in the OS in general.
Your application code is probably not involved. The JVM is still initializing its heap in accordance with your command-line options.
QUESTION
I am working in an environment where I cannot use heap memory but only stack memory. To not be constrained by the #[no_std]
enviroment I tried to use stack memory as heap memory with the linked-list-allocator crate. This was my approach.
ANSWER
Answered 2021-Apr-02 at 10:11After looking into the code and finding what looks a lot like the default entry point I'll put what I think is the confirmation of my guess as an answer: the global_allocator
must be fully initialised before main
, because the default entry point relies on it and allocates: https://github.com/rust-lang/rust/blob/master/library/std/src/rt.rs#L40-L45
QUESTION
If I send a message to a specific queue, before the queue has been created, a queue will be created automatically for me.
The problem is that it leads to a kind of race condition when new messages/queues are added. If my producer service starts and produces a message before the consumer service has started, then a new queue will be created with default values. When the consumer service starts, I would have hoped that it would reconfigure the existing queue with the specific config that I want, but it does not change anything (AutoDeleteOnIdle
, MaxSizeInMegabytes
, etc).
Is there a recommended way to do this? :thinking: Are receive (and subscription endpoints) something that should be configured globally by all services, so that "first one wins"?
The producer service:
...ANSWER
Answered 2021-Jun-11 at 12:37The general guidance is that consuming services should be deployed/started before producing services. And a bus shouldn't be used until it has been started.
While some of the values can be specified as query parameters on the destination address, the only ones supported by Azure Service bus are autodelete
and type
(only one of those is useful to end users).
The queue description/settings aren't updated because they would change constantly if services aren't consistent.
UPDATE: The other reason is that some deploy their topics/queues with resource manager scripts (or something like Terraform) and if MassTransit changed them it would break those deployments by removing their custom settings.
QUESTION
I've read around for several days but haven't been to find a solution... I'm able to build Librosa spectrograms and extract amplitude/frequency data using the following:
...ANSWER
Answered 2021-Jun-11 at 11:34When I get your question right, you want to reconstruct the real/imaginary spectrum from your magnitude values. You will need the phase component for that, then its all simple complex number arithmetic. You should be aware that the output of an STFT is an array of complex numbers, and the amplitude is the absulute value of each number, while the phase is the angle of each number
Here´s an example of a time-domain signal transformed to magnitude/phase and back without modifying it:

As per this Medium post, I'm trying to setup a local Next.js development server with HTTPS.
But when I run this command in Windows 10 Powershell:
...ANSWER
Answered 2021-Apr-15 at 11:40The command is for bash so obviously it can't run in PowerShell. There are many changes necessary
- PowerShell currently doesn't support process substitution (which is that
<(command)
part) so you must save the output into file - The escape character in PowerShell is
`
and not\
so you must replace all those escape characters to the correct one
So the result would be something like this
