I try to develop an App (in xamarin.ios) that simply when find a TAG send an ADPU Command and Recive a responce.
I read lot of documentation but nothing to explain how can I send an ADPU command.
I think is possible, for example reading this: (https://developer.apple.com/documentation/corenfc/nfciso7816tag/3043835-sendcommand)
or this (https://developer.apple.com/forums/thread/118499)
I search if possible:
-Documentation / article / something to read about argument
-Or better a sample code
Can someone help me?
Thanks

I remember seeing an article or example about custom command line in dart, but I can't find the example that I saw.
I want to create an application that looks like a terminal but is actually a full application.
If you know where this custom command line example is, or can provide your own example, that would be greatly appreciated.
Basically, I want to create my own "Powershell" application, but in dart.
The documentation for command line apps should give you everything you need to get started.
I am trying to send some custom metrics(outputs a json) to InfluxDB, are there any plugins or sample scripts that I can use to convert to Line protocol?
Please check https://www.npmjs.com/package/json-to-line-protocol .
You didn't mention about language you want to use to achieve this task so I propose using Node.js with above package that can be easily installed via NPM

Oh now I saw the tag python ... sorry :)
Anyway, as I see it's also easy to find sth for python
Did you check https://github.com/influxdata/influxdb-python ?
I have started using engine-mode for emacs and I love it. For some reason though the Amazon search engine does not work properly. I have used the same structure as advertised in the github website
(defengine amazon
"http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=%s")
and when I try to search for anything emacs returns a "engine/execute-search: Invalid format operation %%D" error. All the other search engines worked flawlessly, and I couldn't find anyone with the same complaint online. I assume there might be some issue with the % signs in URL's?
Thanks in advance for any help on this.
Quoting #VanLaser solution, just use "https://www.amazon.com/s/ref=nb_sb_noss?field-keywords=%s"
I was trying to run a basic program in java by submitting to the job manager in Flink. I have a native library from open CV. When I try to submit the job I get "java.lang.UnsatisfiedLinkError: no opencv_java310 in java.library.path", however when I run it on eclipse by setting up the flink execution environment I get correct results.
I have followed some solutions from the apache flink support website:https://mail-archives.apache.org/mod_mbox/flink-user/201604.mbox/%3CCAO0MGUj_h==sw76-TWF6x8fnT_Vdc84mwu=YLejjn=bG-up+MQ#mail.gmail.com%3E and have modified my conf.yaml file accordingly (by pointing env.java.opts: -Djava.library.path="/path of Open CV library", but no luck,
Maybe my question is very basic , but still I am stuck, any help would be highly appreciated. Thanks :-)
I had a similar problem, often people references something like the "Tomcat" solution. Also, Flink with RocksDB writes the so to a tmp file, but this was also wrong.
If anyone else should pass this way- I wrote a short blog outlining the steps I took. OP's comment answer seems evident, but only after I also see the solution (when I was working on this, it was non-informative).

I am trying to use the file:open(....) function in erlang but it doesn't seem to work. I keep getting an {error, eio} exception.
Ive looked into it in the erlang documentation and all i have found is that it is the posix error for input/output... go figure.
The file name im outputting in is in the formation of "C:/directory/file.txt"
Im not sure if this has something to do with it.
Is there anyway i can make erlang give me a more specific explanation to what is wrong?
Thanks,
Jack
Unfortunately I do not know of a way to find out more without peeking inside the Erlang/VM.
If you look in the windows erlang source code there are a bunch of different errors which could cause en eio error. You can find a list of them here. In order to figure out which specific one it is, I would attach with windbg and step through the code as instrumenting and recompiling it on windows is a pain.
You might also be able to use something like Process Monitor to find out which system calls are being made and what they return.
