on perl5 if someone want to parse binary file he has the pack/unpack utiltiy where he can convert binary structure to perl variables and vice verca ,
is there now a production equivlant for pack/unpack on perl6 ,as from the documentation i found that there are pack/unpack methods for Perl6 but they are experimental ,
does anyone know the status of those functions and if there are alternative to parse binary file which contains a list of records on perl6 ?
You are correct, the pack/unpack methods are experimental; there is currently no other method that is recommended in their place, however.
The experimental flag indicates that the Perl 6 dev team may change the interface. pack & unpack were marked in this way because there was not enough time to review and update the interface before the Christmas release in 2015-12.
I am using rakudo:
use experimental :pack;
pack("C*", [1, 2, 3]); => Buf:0x<01>
I am not sure this is correct use. I expect all bytes get packed in.

I wanted to add a check to an existing terraform build and deployment pipeline to check that the configuration being written by devs is properly formatted and in line with company syntax
Specifically I want to check to make sure they are not using plain resource blocks in thier config as opposed to module blocks
For example I want to I want to make sure they are using
Module “eks_dev_wus2_app_cluster”
And not
Resource “aws_kubernetes_cluster” “eks_dev_wus2_App_cluster”
Current approach
As I understand it I would need to first convert to json to parse through it
terraform show -no-color -json output.tfplan > output.json
Then I should use the jq tool to parse through the output per this article
https://linuxconfig.org/how-to-parse-a-json-file-from-linux-command-line-using-jq
A little fuzzy on how I would go about specifically checking the blocks in the terraform config to confirm whether or not they are resource or module.
Can anyone point me in the right direction?
Is there a better way to get output values? Don’t need an entire solution, just looking to clarify some of the fogginess of approaching this problem
Under the output format, there is a list called resource_changes. Each change has an address field. To meet your requirement, each address should start with module. This makes the developer responsible only for the modules that they are changing with this terraform plan.
Assuming you already have output.json in place, you could do it like this:
LIST=$(cat output.json| jq -r ".resource_changes[].address")
for ADDRESS in $LIST
do
if [[ $ADDRESS != "module."* ]]; then
echo "$ADDRESS is outside of a module"
exit 1
fi
done
I want to convert this NSFW model to CoreML model. What I did:
Download Anaconda 2.7
Install coremltools
Convert this yahoo nsfw model from here - https://github.com/yahoo/open_nsfw/tree/master/nsfw_model but I am not sure it’s Caffe v1 because Apple documentation says that only this version supported. Anyway…
I use this commands for conversion and it converted without any warnings.
coreml_model = coremltools.converters.caffe.convert(('resnet_50_1by2_nsfw.caffemodel', 'deploy.prototxt'), image_input_names='data')
coreml_model.save(’nsfw2.mlmodel')
I imported this model to my project and again all looks fine.
I prepared 224x224 images and use Vision framework like VNImageRequestHandler with cgImage and etc.
But!
All images return the same result
[<VNCoreMLFeatureValueObservation: 0x281b1daa0> 2E00F417-95C0-4AA1-A621-A0945BB5E095 requestRevision=1 confidence=1.000000 "prob" - "MultiArray : Double 1 x 1 x 2 x 1 x 1 array" (1.000000)]
How can I debug this issue and found out what’s wrong?
Maybe you're looking only at naughty images? ;-)
It's probably the image preprocessing. You didn't specify any preprocessing options while Caffe models usually normalize using ImageNet mean/std. Refer to my blog post for more info: https://machinethink.net/blog/help-core-ml-gives-wrong-output/
However, I don't see any normalization options in your deploy.prototxt, so perhaps it's not that.
How I would debug this: remove everything but the first layer from the Caffe model and convert to Core ML. Run this one-layer model in both Caffe and Core ML and compare the outputs. If they are different, something is up with how you're loading or preprocessing the input data.
I am using Free Pascal (Lazarus) to develop a simple server daemon. The problem I am facing is that the TEventLog component does not write to the systemlog.
I use the following code:
EventLog1.LogType := ltSystem;
EventLog1.Active := True;
EventLog1.Log('Application has started!');
Instead of writing to systemlog it creates a file with the name as the executable and writes there.
Is there any other way I can write to the system log ? Is openlog defined in any unit I can use ?
(Assuming you use a *nix and the most recent 2.6.2 version).
No, libc log* functions seem only declared in the implementation of eventlog. Maybe they are in unit libc, but that is mostly unsupported, and linux/32bit only.
Check some assumptions:
Is active false before you set logtype, otherwise the active:=true might not recheck it.
you want to write system log, do you have enough privileges for that?
Do you see anything with strace/ktrace/truss ?
I'm desperately trying to send a message as JSON to a PHP script.
destination d_php {
program("/usr/bin/php -f /data/htdocs/log.php" template("$(format-json)\n") ) ;
};
The php script is fine. Using simple macros works well, but the "format-json" function does always return this:
error in template: $(format-json)
I tried everything I could find in the documentation, but all response I get is "error in template". The official docs (link) even use 2 different spellings, not very promising.
Any ideas?
the format-json and format_json syntax should both work, hyphens and underscores are equivalent in syslog-ng.
As for the actual problem, have you tried setting the scope parameter of format-json, like "$(format_json --scope selected_macros)"? By default, it is empty, which means there is nothing to format.
HTH,

Found the reason. Apparently, syslog-ng is split into separate packages on Ubuntu (12). I had to install syslog-ng-mod-json.
It's really a shame that syslog-ng doesn't give the slightest hint that the function is missing or unknown, instead of some general error.
If you are compiling from the source, you shall install json-c library first (yum install json-c-devel).
What is an alternative to autotools in Haskell world? I want to be able to choose between different configurations of the same source code.
For example, there are at least two implementations of MD5 in Haskell: Data.Digest.OpenSSL.MD5 and Data.Digest.Pure.MD5. I'd like to write code in such a way that it can figure out which library is already installed, and didn't require to install the other.
In C I can use Autotools/Scons/CMake + cpp. In Python I can catch ImportError. Which tools should I use in Haskell?
In Haskell you use Cabal configurations. At your project top-level directory, you put a file with the extension .cabal, e.g., <yourprojectname>.cabal. The contents are roughly:
Name: myfancypackage
Version: 0.0
Description: myfancypackage
License: BSD3
License-file: LICENSE
Author: John Doe
Maintainer: john#example.com
Build-Type: Simple
Cabal-Version: >=1.4
Flag pure-haskell-md5
Description: Choose the purely Haskell MD5 implementation
Default: False
Executable haq
Main-is: Haq.hs
Build-Depends: base-4.*
if flag(pure-haskell-md5)
Build-Depends: pureMD5-0.2.*
else
Build-Depends: hopenssl-1.1.*
The Cabal documentation has more details, in particular the section on Configurations.
As nominolo says, Cabal is the tool to use. In particular, the 'configurations" syntax.
