Donald Knuth

Programming Legend

Dear Abdur-Rahmaan,

Please excuse the fact that I haven't had time to look at your email message from April until today.

In that program, MOVEIN is not an instruction; it is a symbolic name for the address where a dynamically changing instruction will be stored. (His computer was a LOT different from what we have now!)

Line 41 of the program says that we should reserve one "storage tank" (RST 1) to be called MOVEIN. Line 46 puts a PIK instruction into that storage tank. Eventually, control is transferred so that the machine executes that PIK instruction (which moves a block of words into a sequence of short tanks called BUFFER).

Thanks for your interest in history, and for your patience.

Best wishes, Don Knuth (source)

Software Engineer, Facebook

I worked with Abdur at Metabob and when he came in he was able to lead our team in terms of having a proper system design to documentation. He was able to make the engineering team more productive than it was before. If you are looking for an engineer who is strong technically he is the one that can do it. His experience with open source is one of the biggest plus he has bought to the team.

Shamsuddin Rehmani

Software Development Engineer, Amazon

I worked with Abdur-Rahmaan's on one of his many open source software project, Shopyo. As this was my first time contributing to open source, I was not very confident in my skills. However, Abdur-Rahmaan was very patient and helped with the process of project setup and contribution. Looking back since my first open source contribution, I couldn't have asked for a better mentor than Abdur-Rahmaan. As I worked more with him, I learned that he has a vast knowledge not only of software engineering but also possess excellent communication and leadership skills. His attention to details, clear guidance, pursuit of best industry practices, and past experience and success in managing a team of engineers makes him a great leader and asset to any team.

As if this was not enough, he also possess the gift of being artistic and creative, with the ability to make software not only functional but also marketable with design skills that he pursues as a hobby.

His work in both professional and open source setting speaks itself but this recommendation is just a token of appreciation on behalf of countless engineers whom he has helped improve and break into the open source community. I wish him the best in his future endeavors and I am excited to see where his work takes him.

I have worked with Abdur-Rahmaan on different programming assignments in C++ and data science projects in Python.

His exceptional understanding of coding paradigms, ability to grasp high-level material quickly and his outstanding communication skills make him a great lad to work with.

I have benefited extensive from his deep understanding of pandas, NumPy and SciPy libraries of Python on my work in Artificial Neural Network.

He would be a great fit any organisation or team

Gico Carlo Evangelista

Software Engineer at Outward Inc.

I have worked with Abdur-Rahmaan on one of his Open Source Python projects on GitHub. He has helped mentored me in not only understanding the project thoroughly, but has also taught me the basics of contributing to an open source repository. He is very helpful when it comes to answering questions to both experienced developers and newcomers who are interested in learning about open source. Abdur-Rahmaan is a great mentor who I recommend working with.

Justin Triplett

Software Engineer and Consultant at Caledonia Systems

Working with Abdur-Rahmaan has been a really great experience. He did so much to make sure Flaskcon was a great success. He organized the teams of volunteers and stepped up to fill roles and provide advise wherever and whenever needed. I love working on a project knowing someone else is as dedicated to it's success as I am and I look forward to working with him again soon.

Nathan Heron - Morris

Junior Software Engineer at Dream Agility

Abdur-Rahmaan and his open source project has helped me not only with confidence in my coding skills but, also helped me think about the effects of explaining and documenting my contributions so others can understand what I have contributed. Abdur-Rahmaan has also been willing to answer any questions I may of had without judgement and provided me with some education in design principles. From the confidence Abdur-Rahmaan has helped me with. I have managed to land my first role as a software engineer with a great company that is solving problems with Artificial intelligence. So I would just like to say thank you.

Zahur Meerun

Full Stack Software Development Student/First officer at Air Mauritius

I have known Abdur-Rahman for over 2 years since I started my coding journey. At that time he provided me with advice on how to navigate such a career. Recently he assigned me a project which involved the integration of several modules using an Open Source Framework whereby I reported directly to himself.

I cannot speak highly enough of his programming ability and vision in tackling technical issues. He was always available for meetings to address hiccups that I had during the project. The experience I have had working with him has been extremely pleasant and beneficial for me and would recommend him for any projects you might have.

Girish Mahabir

Abdur-Rahmaan is a great mentor. He is very patient when onboarding new members into open source projects and his communication skills are second to known. His vast experience is clear through the effective advice that he gives. He is very good at managing teams and I consider him an expert in all things Python. I hope to work more with him in the future!

Hans Maulloo

I had the pleasure of working with Abdur-Rahmaan for the FlaskCon 2020. He was a great team player, well organized and very consistent when it came to managing the event. We had organising members from different corners of the world and Abdur made sure remote meetups were organised on a regular basis and would always follow the agenda. Even when facing technical difficulties, he was always ready to help out. I'd gladly work with Abdur on any related project :)

Chukwudi Nwachukwu

Abdur is the founder of an IRC python GitHub project that I started collaborating on. I was impressed with your skills! He is the creator of several python initiatives like organizations and code projects. Always adopting the latest technologies and still mastering 3 languages ​​too! Despite this, he still manages to be an extremely compassionate person, always encouraging and supporting newbies like me. Thank you my friend! Success always!

For the love of it

Python Mauritius Usergroup

Started the usergroup for Mauritius: pymug.com

  • Only (maybe) usergroup having end of year reports. See 2019 and 2020
  • We had an Ai mini course by different members of the ug with certificates of participation signed by the dean of faculty
  • We organised python from scratch sessions
  • We organised a mini course on Web Scraping, covering from requests to infinite feed scraping
  • We organised online Python sessions at the Uni of Mauritius on different topics during lockdown 2020. We had web dev, ai and more.
  • We became an O’reilly media partner
  • We invited speakers from different countries for our meetups like Mridu Bhatnagar for example.
  • Our members spoke at different confs from PyCon Tanzania to EuroPython
  • We invited industry experts to present their Python insights, Dr. Heman Mohabeer for example.
  • We managed to pull in paid Python tasks for our members
  • Members managed to find more locations to organise meetups
  • Managed to maintain regularity even in the pandemic period

FlaskCon

Wrote the original draft for FlaskCon: flaskcon.com

  • Contacted various entities to support the conf and provide experience and help
  • Communicated with Pallets about the terms and direction of the conf
  • Asked the PSF in collaboration with Pallets to make FlaskCon a PSF-backed conference
  • Composed team
  • First edition hosted great speakers including PSF director Dustin Ingram, well known maintainers and people from the federal gov
  • Adopted a community-first approach and sacrifised sponsors to get the conf running
  • Second edition ongoing 2021

Flask Community Workgroup

Instituted it with the help of Pallets and Flask folks: FlaskCWG. It’s the logical conclusion of FlaskCon.

  • Aim to cater for the Flask community including events, abandoned plugins, workshops and translations
  • Pallets instituted Pallets-eco to cater for abandoned plugins
  • Translations started substantially for chinese, spanish and french with instituted protocols

Arabic Coordinator for The Python Docs

Stated the translations with ups and downs

  • Managed to find another coordinator before he got busy. Back to being the coordinator

Python-efl revival

Helping make EFL and Python-efl specifically more accessible. EFL is what Samsung’s Tizen uses for smartwatches etc. It’s one of the aspects which enables Bodhi Linux to fly on low specs while being an everyday OS

  • Helping out with dead Bodhi Linux’s Python-efl apps
  • Updated Jeff’s series (the only Python-elf tutos) to reflect current versions
  • Davide Andreoli agreed to put a Github mirror for Python-efl to better reach out to the community

PyHerald

Mailing lists summary and news. site

  • Brings to general readership Python mailing list discussions
  • Catches important but easy to miss news
