QUESTION
I encountered a problem while trying to get my java project running on my Debian 10 server. Everything seems to work, but java throws an error when i try to get an instance of a MessageDigest with "SHA256".
It occurs in this line:
MessageDigest digest = MessageDigest.getInstance("SHA256");
The exception:
java.security.NoSuchAlgorithmException: SHA256 MessageDigest not available
Is there a way to install SHA256 functionality or another way i can create a sha256 hash?

QUESTION
I'm implementing Testing Library with Puppeteer and I was trying to use an environment variable, DEBUG_PRINT_LIMIT, to limit the length of the HTML printed to console in case of failure.
But for some reasons, the variable environment is just ignored by the library...
My project:
package.json

It's actually a bug in the library itself: https://github.com/testing-library/pptr-testing-library/issues/55

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
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 a super simple script to confirm this behavior:
leak.sh
ANSWER
Answered 2021-Jun-13 at 23:12As mentioned by @oguz_ismail in the comments, bug-bash@gnu.org
is the appropriate place to report the bug.
However, a certain format for the email is required/requested, when you need to report a bug.
All bug reports should include:
- The version number of Bash.
- The hardware and operating system.
- The compiler used to compile Bash.
- A description of the bug behaviour.
- A short script or ‘recipe’ which exercises the bug and may be used to reproduce it.
You can find ALL the details at: https://www.gnu.org/software/bash/manual/html_node/Reporting-Bugs.html
Finally, there is a helper script built into bash
itself. Call bashbug
from the command line, and it will populate most of the requirements, leaving you to fill out the description and the steps required to reproduce the bug.
QUESTION
TLDR: Create a CRC from every file(contentbased) in Directory.
Currently i used from Cpp20 the Filesystem Libary and tried to create a checksum for a file with "hash_value(p)". The thing is, the value does not change. Can you provide me some advice ho to accomplish a checksum, that changes when file content is changed. I would like to stay within the range of CPP libarys or what debian 10 can provide.
Now i tried this:
ANSWER
Answered 2021-Jun-12 at 16:59The thing is, the value does not change.
It's not supposed to. The filesystem::hash_value
is a hash of the path to the file, not the contents of the file. If you want to compute a CRC of the contents of a file, you're going to have to read those contents and apply a CRC algorithm to them.

QUESTION
I'm using SBCL 2.0.1.debian and Paul Graham's ANSI Common Lisp to learn Lisp.
Right in Chapter 2 though, I'm realizing that I cannot use setf
like the author can! A little googling and I learn that I must use defvar
or defparameter
to 'introduce' my globals before I can set them with setq
!
Is there any way to avoid having to introduce globals via the defvar
or defparameter
, either from inside SBCL or from outside via switches? Do other Lisp's too mandate this?
I understand their value-add in large codebases but right now I'm just learning by writing smallish programs, and so am finding them cumbersome. I'm used to using globals in other languages, so don't necessarily mind global- / local-variable bugs.
...ANSWER
Answered 2021-Jun-11 at 11:29If you are writing programs, in the sense of things which have some persistent existence in files, then use the def*
forms. Top-level setf
/ setq
of an undefined variable has undefined semantics in CL and, even worse, has differing semantics across implementations. Typing defvar
, defparameter
or defconstant
is not much harder than typing setf
or setq
and means your programs will have defined semantics, which is usually considered a good thing. So no, for programs there is no way to avoid using the def*
forms, or some equivalent thereof.
If you are simply typing things at a REPL / listener to play with things, then I think just using setf
at top-level is fine (no-one uses environments where things typed at the REPL are really persistent any more I think).
You say you are used to using globals in other languages. Depending on what those other languages are this quite probably means you're not used to CL's semantics for bindings defined with def*
forms, which are not only global, but globally special, or globally dynamic. I don't know which other languages even have CL's special / lexical distinction, but I suspect that not that many do. For instance consider this Python (3) program:
QUESTION
I built a Net Core 5 Web API in .Net 5 Docker Image and was searching for a way to run create container from that image on ARM v7 Processors like Tinker Board with Debian on it.
...ANSWER
Answered 2021-Jun-11 at 21:12Lastly, on the following website, I found the base for building and running the app on ARM Processors: https://hub.docker.com/_/microsoft-dotnet-aspnet
Scroll down on the page to 'Full Tag Listing' and select base for your architecture.
You just need to change the base'FROM ...'(in DockerFile) according to your processor architecture and run the Docker build command and an image will be build specifically for your ARM or any other Device.
For ex. I am running docker container on Tinker Board with Debian installed on it and current .NET Runtime is .NET 5, so my Dockerfile look like this:
Don't copy blindly. Read the above text first.
QUESTION
we use multiple PHP workers. Every PHP worker is organized in one container. To scale the amount of parallel working processes we handle it in a docker swarm.
So the PHP is running in a loop and waiting for new jobs (Get jobs from Gearman). If a new job is receiving, it would be processed. After that, the script is waiting for the next job without quitting/leaving the PHP script.
Now we want to update our workers. In this case, the image is the same but the PHP script is changed. So we have to leave the PHP script, update the PHP script file, and restart the PHP script.
If I use this docker service update command. Docker will stop the container immediately. In the worst case, a running worker will be canceled during this work.
...ANSWER
Answered 2021-Jun-11 at 20:48In the meantime, we have solved it with SIGNALS.
In PHP work with signals is very easy. In our case, this structure helped us.
