install – Big Sur 11.3 : rebuild the index of all installed Macport packages

Following a lot of error messages when I wanted to install a Macport package on my new MacOS book pro Big Sur 11.3, and having no problem on another MacBook with Big Sur 11.3 also, I decided to do a “raw” copy of the directory /opt/local from the working MacBook to the first one with which I have problems.

Now, I would like to rebuild an index of all Macport packages copied on the new MacBook.

Indeed, if I want to install a Macport package, I get :

sudo port search listofitems
Error: Current platform "darwin 20" does not match expected platform "darwin 19"
Error: If you upgraded your OS, please follow the migration instructions:
OS platform mismatch
    while executing
"mportinit ui_options global_options global_variations"
Error: /opt/local/bin/port: Failed to initialize MacPorts, OS platform mismatch

Have I to copy an index file from the working Macport installation of other MacBook on the new one ? I didn’t find such a file.

As you can see above in the error messages, there seems to be a problem of platform :

Error: Current platform "darwin 20" does not match expected platform "darwin 19"

Please, if someone could help me to rebuild the new packages installed, rather copied in a raw way, but I hope this is possible to get this current index file.

packages – CharacterTable for symmetric groups $S_n$ with large $n$

I am looking for a package to generate character tables for symmetric groups $S_n$. At this moment I am using

FiniteGroupData[{"SymmetricGroup", n}, "CharacterTable"]

but it works only for $nleq 10$. Does there exist a package which can be used to get similar results for larger values of $n$?

updating – What is the best practice for handling abandoned packages required by the drupal core?

When I run composer update on a Drupal 9 website, I get this warning:

Package doctrine/reflection is abandoned, you should avoid using it. Use roave/better-reflection instead.

A similar question has alreday been asked, answered and accepted on StackOverflow.

To summarise the accepted answer:

  • edit your composer.json and replace the abandoned package with the recommended replacement
  • then run composer update again

However, that answer doesn’t apply in the case of “doctrine/reflection”. When looking into my composer.json, there is no mention of it, so there is nothing to edit.

So I am checking why it is required:

$ composer why doctrine/reflection
doctrine/common          2.13.3  requires  doctrine/reflection (^1.0)   
doctrine/persistence     1.3.8   requires  doctrine/reflection (^1.2)   
drupal/core              9.1.7   requires  doctrine/reflection (^1.1)   
drupal/core-recommended  9.1.7   requires  doctrine/reflection (1.2.2)  

So this abandoned package is required by drupal/core (and others).

Two questions:

  1. Why is the most recent version of drupal/core requiring an abandoned package (instead of its recommended replacement roave/better-reflection)?
  2. What is the best practice for handling abandoned packages required by the drupal core?

Exporting packages containing “Python Code” cells

I created a notebook with Python code cells (evaluated using External Evaluate) as can be created by typing > at the beginning of a cell. (And choosing Python for the external evaluator). I then marked these cells as initialization cells. However, I find that I can’t reliably create packages (I create packages autoamtically using the answer in The python cells do become python cells in the package but they get corrupted. It wrongly breaks cells up at any double new line (this can at least be avoided) but also randomly misses text. A cell with

import scipy.optimize
import numpy as np
def stuff():

just becomes
import scipy.optimize
import numpy as
def stuff():

and thus gives a syntax error since np is missing. The original notebook file works perfectly and has no such errors.

Is there any reliable way to export? Does everyone have these issues?

Version: “12.1.1 for Linux x86 (64-bit) (June 19, 2020)”

It gets even weirder. There seems to be some randomness to it. Now I managed to (without making changes) export it correctly to a package that does not produce any errors when run from within MMA (i.e. when opening it and running all the cells.) However, when calling it from another notebook using Get I still get a syntax error. I checked and see no syntax error in the cell where it should supposedly be.

It might be related to having set up a custom virtual environment using this answer. However, everything is working perfectly in the notebook. The issues only arise when converting to a package.

sql server 2008 – Can SSIS packages call other SSIS packages in the connection string?

I am running an SSIS package that transfers data from one (SQL2008) server to another (SQL2000). However after P2V conversion the SQL2008 server cannot execute an SSIS package due to a user authentication error.

Lets say the package is called “Transfer-Go”. In the connection string of that package can it call another SSIS package? In the SSIS library there is another package with the same that appears in the string (called Transfer-Now) name The string is below:

Data Source=<IP>;User ID=<user>;Initial Catalog=<db_name>;Provider=SQLNCLI10.1;Persist Security Info=True;OLE DB Services=-13;Auto Translate=False;Application Name=SSIS-<Transfer-Now-name of other SSIS package>-{8ABA18EE-637E-424F-A3F7-F7E4EA50DD9D}<IP.db_name.user>;

So is this SSIS package connection string calling that package?

And if the credentials are wrong in that package could that be why I am unable to authenticate?

Thanks for any input, not a DB/SQL guy at all so I apologize if I sound green here.

macos – Cant update/install homebrew packages with Kaspersky Security Software (Self Signed Cert)

At work we have Kaspersky installed. Kaspersky installs a self signed cert so it can decrypt/inspect web traffic. Chrome and everything works fine except for homebrew. When i try to install/update software this is what i see:

brew install yarn
==> Downloading
######################################################################## 100.0%##O#- #
curl: (35) error:1400443E:SSL routines:CONNECT_CR_SRVR_HELLO:tlsv1 alert inappropriate fallback
Error: Failed to download resource "yarn"
Download failed:

Since it appears its a curl issue i tried to create a .curlrc file with insecure but that doesn’t help at all. I’m able to call one of our IT admins over and temporarily turn off web anti-virus but that is starting to be a major pain every time i install/update software. They aren’t, of course, going to allow me to permantely turn it off. I have this issue on no matter what mac i use (one is a m1 based mac and the other is an intel based mac).

Composer require drupal/social_auth_google – Your requirements could not be resolved to an installable set of packages

Previously I got an error with the command

composer require "drupal/social_auth_google:^2.0"

So I tried;

composer require "drupal/social_api:2.x-dev" "drupal/social_auth:2.x-dev" "drupal/social_auth_google:2.x-dev" 

But now composer throws up faults no matter what I do. I tried removing all the “social” entries from composer.json but here are the errors I get instead;

    Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires drupal/title_field_for_manage_display ^1.0, found drupal/title_field_for_manage_display(1.0.0, ..., 1.12.0) but the package is fixed to 2.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
  Problem 2
    - drupal/social_auth_google(2.0.0, ..., 2.1.0) require drupal/social_auth ^2.0 -> drupal/social_auth is fixed to 2.x-dev (lock file version) by a partial update but that version is rejected by your minimum-stability. Make sure you list it as an argument for the update command.
    - Root composer.json requires drupal/social_auth_google ^2.0 -> satisfiable by drupal/social_auth_google(2.0.0, 2.1.0).

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Here’s my composer.json ;

How can I fix composer?

packages – Get notation rule list so far

One can get list of every variable name so far by


Likewise, is there a code to get list of every user-defined notation rule(using notation package) so far? like


In that list, can I distinguish whether a notation rule is effective at present /or not?
