    @HDembinski, @lukasheinrich, on the pylhe & pyhepmc merging: could you Lukas then open an "issue" or 2 on the pyhepmc repo so that one can easily read what you would like to see available? Just so that it's easier to figure out what kind of user code one is talking about.
    From a quick look there are no tests in there. Would you have a .lhe file to provide for testing? Thanks :-).

    ah man can't we kill LHE? its so inefficient to use xml

    @jpivarski very nice. i looked for a thumbs-up button - but no such thing in gitter.

    @nsmith-, I run away from XML as much as I can ;-). I'm not a user of LHE files but others are ...

    @nsmith- does madgraph produce output files other than LHE files?

    Hi all. Tomorrow is the first day of the SciPy 2020 call for proposals: https://twitter.com/SciPyConf/status/1204141195095662594

    I will be submitting one for pyhf and I hope that other people will be making submissions for talks and posters as well. It is a highly competitive candidate pool where they annually get hundreds of applications for a few tens of speaking spots (last year there were 168 applications for 60 spots), so I'd encourage everyone applying to take a look at talks from previous years (up on the Enthought YouTube channel) and applications to see what successful talks looked like.

    If it is of interest, I have my proposal for a pyhf talk last year up on GitHub. It wasn't accepted for a talk, but it reviewed well enough that it was invited for a poster anyway. The reviewer comments are also included. https://github.com/matthewfeickert/SciPy2019-Proposal/

    Hi everyone!
    I'm a sophomore computer science and engineering undergrad from the Indian Institute of Information Technology Sri City, India.
    I'm new to Open Source Contributions. Though I really wish to do my part and contribute in anyway to CERN.
    Could anyone please guide me here? 😅

    And, since no one has posted it: https://pythonclock.org runs out tonight! Though, to be fair, the final release of Python 2.7 (2.7.18) actually comes out in April - tonight is just the code freeze.
    Hans Dembinski
    @HDembinski
    The animation of Marcus Borba looks cool, but since he does not reveal where the data came from, it is unciteable...
    I still enjoyed watching it. It is interesting to see how there is the age of Pascal, which fades, then comes the age of Java, etc. Now seems to be the age of Python :+1:
    C++ is also still one of the top compiled languages.

    The article about the Zen of Python is very good for those who do not click with the Zen of Python intuitively as I did. Most of it only starts to make sense when you gain some experience with designing software and fell into a few traps along the way. These guidelines are great. They are guidelines, not rules, but if you follow them, your software becomes much better.

    (Sorry for the cross-post; but I can't be sure how much overlap there is between Scikit-HEP and PyHEP.)

    From HSF-GSoC:

    Less than a week until the deadline for submitting GSoC project ideas !

    We are sending this gentle reminder targeting people who are planning to submit a proposal for this year's GSoC, but who did not make yet a pull request in the HSF repository. The deadline is next Tuesday, Feb 4 as announced already few times. We have less than 10 proposals so far, only 5 published and the rest being reviewed; last year we had 54 proposals! Please do not let this submission for the last minute since there is also a review process.

    For convenience, here are the instructions (https://hepsoftwarefoundation.org/gsoc/guideline.html) for submitting a proposal. In case you have problems doing this yourself, do not hesitate to send the proposal content (following the format from the guideline) by e-mail to the admin team.

    Hi! I will be giving a talk titled "Python in High Energy Physics" at PyCon US in April. I have a window to make changes to my abstract and I would greatly appreciate any suggestions about what you would like to see in the talk or if you would like me to make any changes to my abstract. Here is a link to the abstract that was accepted - https://docs.google.com/document/d/1MHOPUB9KYjG1A_RQ67fyNgPoy5-jxbvcCrQQZmcQ7Ys/edit?usp=sharing

    @eduardo-rodrigues
    Hi @reikdas, I've just added a few comments.
    Now, I find the abstract very ambitious when I read "The talk starts with a look at what computing has looked like in the field of High Energy Physics in the past and how a lot of physicists have played major roles in the development of Computer Science. It then explores the emergence of Python as the language of choice for several physicists and two of the major libraries that have been vital to the adoption of Python in the High Energy Physics community - cppyy and uproot.". The first sentence, in particular, reflects a gigantic scope and I wonder how you're going to approach that? Its experiment software stacks for reconstruction and analysis, trigger software, distributed computing, frameworks, analysis software, simulation; you name it. I would find it far more realistic to focus solely on analysis, and that is already a big thing itself, actually. So, bottom line, I'm worried that you end you providing a very biased and potentially misleading message. Apologies if I seem negative.
    Can you clarify?
    Pratyush Das
    @reikdas
    "The talk starts with a look at what computing has looked like in the field of High Energy Physics in the past" - I was mainly going to talk about PAW and the emergence of ROOT. I guess I do mean just analysis.. (I'll update the abstract to reflect it). "and how a lot of physicists have played major roles in the development of computer science" - I was thinking of something similar to slide 9 of Jim's talk (https://github.com/jpivarski/2019-09-13-history-strangeloop).
    Eduardo Rodrigues
    @eduardo-rodrigues
    Thanks for the link. Yes, this kind of historical statements are good. But you will have to be very brief on the "general intro" ;-).
    In any case, do keep in touch with PyHEP so that the talk is "the best possible" ...
    Pratyush Das
    @reikdas
    Sure. Thanks!

    More of interest for the PyHEP 2020 organizers, but when I was at the Lake Louise Winter Institute I met Claudio Kopper (https://pa.msu.edu/profile/kopper/) who works on IceCube and he seemed quite keen about PyHEP. So we will hopefully have someone from his group attending
    Eduardo Rodrigues
    @eduardo-rodrigues
    Thanks @matthewfeickert. It would be great to see participation from IceCube and others at the workshop.

    PyHEP 2020 Workshop, July 11-13 2020, Austin (Texas), USA

    Dear colleague,

    We are pleased to announce the third PyHEP workshop organised by the HEP Software Foundation (HSF). The PyHEP, "Python in HEP", workshops aim to provide an environment to discuss and promote the usage of Python in the HEP community at large.

    PyHEP 2020 will be held in Austin (Texas), USA, on 11-13 July 2020. The workshop will take place in the same city as the SciPy 2020 conference ((https:/www.scipy2020.scipy.org/) on scientific computing in Python, and will slightly overlap in time with it, to facilitate inter-community exchanges. We encourage HEP participation in SciPy.

    The workshop will be a forum for the participants and the community at large to discuss developments of Python packages and tools, exchange experiences, and inform the future evolution of community activities. There will be ample time for discussion.

    The agenda will be made available on the workshop indico page (https://indico.cern.ch/e/PyHEP2020/) in due time. It is also linked from the PyHEP WG homepage (http://hepsoftwarefoundation.org/activities/pyhep.html).

    We encourage community members to propose presentations on any topic (email: pyhep2020-organisation@cern.ch). We are particularly interested in participation that diversifies the backgrounds of attendees - non-LHC communities, neutrino experiments, etc.

    Registration will open in Spring and we will provide detailed travel and accommodation information at that time. There will be no workshop fees, thanks to our sponsors.

    Some partial travel support based on need is available for some USA/UK participants, in particular for students and postdocs. We thank IRIS-HEP, the University of Liverpool and the UK Software Sustainability Institute (SSI) for this. Details on how to apply for these will be provided once registration opens.

    Media information:

    Looking forward to your participation!

    Organising Committee
    Eduardo Rodrigues - University of Liverpool (Chair)
    Ben Krikler - University of Bristol (Co-chair)
    Jim Pivarski - Princeton University (Co-chair)
    Chris Tunnell - Rice University
    Matthew Feickert - University of Illinois at Urbana-Champaign
    Peter Onyisi - The University of Texas at Austin

    PEP 584 was merged into Python 3.9. This will allow dictionaries to be combined, that is, dict1 | dict2 or dict |= other_dict

    PyCon USA got cancelled. They have given speakers the option to record their talks and submit it to be uploaded on PyCon's youtube channel, so I'll probably be doing that.

    @Ojaswy
    Is the application for presenting at the event still open? I am intersted.
    Jim Pivarski
    @jpivarski

    @Ojaswy Are you asking about PyCon or PyHEP? The PyCon abstract-submission must be closed because acceptances had already been announced (like @reikdas's).

    As for PyHEP 2020 in July, we haven't said much publicly yet because we're still figuring out the new format, but it will be held as an online workshop. (That much, at least, has been established. How we're going to have online interactions with the same quality as face-to-face interactions is a problem we're still working on.)

    @Ojaswy
    Hello @jpivarski, I am interested in presenting at PyHEP. In @eduardo-rodrigues message above it's mentioned that community members are encouraged to propose presentations. I would like to know more details about that (any requirements for presenters and topics)
    If permitted off the top of my head, I would like to talk about HL-LHC project and how ML can help us in analysis.
    Eduardo Rodrigues
    @eduardo-rodrigues
    Hello @Ojaswy, that's right, we encourage abstract submissions as it won't be just invited talks. As @jpivarski says, we are reorganising the workshop because of covid-19. We will send another email as soon as we're set. As for details, abstracts are informal-ish, and it's done via the email provided on the PyHEP 2020 Indico agenda (not on this cht ;-)). The one requirement is that it fits the workshop scope, of course, so Python is central ...

    @Ojaswy
    @eduardo-rodrigues @jpivarski How do I be a part of the mailing list to receive any updates on the program?
