Dmitry Shachnev: ReText turns 10 years

Exactly ten years ago, in February 2011, the first commit in ReText git repository was made. It was just a single 364 lines Python file back then (now the project has more than 6000 lines of Python code). Since 2011, the editor migrated from SourceForge to GitHub, gained a lot of new features, and most importantly now there is an active community around it, which includes both long-time contributors and newcomers who create their first issues or pull requests. I don t always have enough time to reply to issues or implement new features myself, but the community members help me with this. Earlier this month, I made a new release (7.2), which adds a side panel with directory tree (contributed by Xavier Gouchet), option to fully highlight wrapped lines (contributed by nihillum), ability to search in the preview mode and much more see the release page on GitHub. Side panel in ReText Also a new version of PyMarkups module was released, which contains all the code for processing various markup languages. It now supports markdown-extensions.yaml files which allow specifying complex extensions options and adds initial support for MathJax 3. Also check out the release notes for 7.1 which was not announced on this blog. Future plans include making at least one more release this year, adding support for Qt 6. Qt 5 support will last for at least one more year.

Gregor Herrmann: RC bugs 2016/52-2017/07

debian is in deep freeze for the upcoming stretch release. still, I haven't dived into fixing "general" release-critical bugs yet; so far I mostly kept to working on bugs in the debian perl group: thanks to the release team for pro-actively unblocking the packages with fixes which were uploaded after the begin of the freeze!

Juliana Louback: PaperTrail - Powered by IBM Watson

On the final semester of my MSc program at Columbia SEAS, I was lucky enough to be able to attend a seminar course taught by Alfio Gliozzo entitled Q&A with IBM Watson. A significant part of the course is dedicated to learning how to leverage the services and resources available on the Watson Developer Cloud. This post describes the course project my team developed, the PaperTrail application.

Project Proposal Create an application to assist in the development of future academic papers. Based on a paper s initial proposal, Paper Trail predicts publications to be used as references or acknowledgement of prior art and provides a trend analysis of major topics and methods. The objective is to speed the discovery of relevant papers early in the research process, and allow for early assessment of the depth of prior research concerning the initial proposal.

Meet the Team Wesley Bruning, Software Engineer, MSc. in Computer Science Xavier Gonzalez, Industrial Engineer, MSc. in Data Science Juliana Louback, Software Engineer, MSc. in Computer Science Aaron Zakem, Patent Attorney, MSc. in Computer Science

Prior Art A significant amount of attention has been given to this topic over the past few decades. The table below shows the work the team deemed most relevant due to recency, accuracy and similarity of functionality. priorArt The variation in accuracy displayed is a result of experimentation with different dataset sizes and algorithm variations. More information and details can be found in the prior art report. The main differential of PaperTrail is providing a form of access to the citation prediciton and trend analysis algorithm. With the exception of the project by McNee et al., these algorithmns aren t currently available for general use. The application on researchindex.net is open to use but its objective is to rank publications and authors for given topics.

Algorithm Citation Prediction: PaperTrail builds on the work done by Wolski s team in Fall 2014. This algorithmn builds a reference graph used to define research communities, with an associated vector of topic scores generated by an LDA model. The papers in each research community are then ranked by importance within the community with a custom ranking algorithm. When a target document is given to algorithm as input, the LDA model is used to generate a vector of topics that are present in the document. The communities with the most similar topic vectors are selected and the publications within these communities with highest rank and greatest similarity to the input document are recommended as references. A more detailed description can be found here. Trend Analysis: Initially, the idea was to use the AlchemyData News API to obtain statistics pertaining to the amount of publications on a given topic over time. However, with the exception of buzz-words (i.e. big data ), many more specialized topics appeared very infrequently in news articles, if at all. This isn t entirely surprising given the target audience of PaperTrail. As a work around, we use the Alchemy Language API to extract keywords from the abstracts in the dataset, in addition to relevance scores. The PaperTrail database could then be queried for entry counts for a given year and keyword to provide an indication of publication trends in academia. Note that the Alchemy Language API extracts multiple-word keywords as well as single words.

Data To maintain consistency with Wolski s project, we are using the DBLP data as made available on aminer.org. The DBLP-Citation-network V5 dataset contains 1,572,277 entries; we are limited to the use of entries that contain both abstracts and citations, bringing the dataset size down to 265,865 entries.

Architecture A high-level visualization of the project architecture is displayed below. Before launching PaperTrail, it s necessary to train Wolski s algorithm offline. Currently any documentation with regard to the performance of said algorithm is unavailable; the PaperTrail project will include an evaluation phase and report the findings made. The PaperTrail app and database will be hosted on the Bluemix Platform. ptArchitecture

Status Report Phases completed:
  • Project design
  • Prior art research
  • Data cleansing
  • Development and deployment of an alpha version of the PaperTrail app
Phases under development:
  • Algorithm training and evaluation
  • Keyword extraction
  • MapReduce of publication frequency by year and topic
  • Data visualization component

Gregor Herrmann: RC bugs 2014/38-43

it's this time of the year^Wrelease cycle again almost. in ten days (& roughly two hours), the freeze for the next debian release, codenamed jessie, will start. by this time packages must be in testing in order to be candidates for the release, as explained in the release team's detailed freeze policy. this also means, with the regular testing migration time set to ten days, that tonight's dinstall run closed the regular upload window. & this also means that we should all concentrate on fixing RC bugs to make the freeze as short as possible & jessie yet another great release. before I head over to the UDD bugs page, I'd like to summarize my work on RC bugs in the last weeks, which was again focussed on packages in the Debian Perl Group.

Gregor Herrmann: RC bugs 2013/49 - 2014/12

since people keep talking to me about my RC bug fixing activities, I thought it might be time again for a short report. to be honest, I mostly stopped my almost daily work at some point in december, partly because the overall number of RC bugs affecting both testing & unstable is quite low (& therefore the number of easy-to-fix bugs), due to the auto-removal policy of the release team (kudos!). but I still kept track about RC bugs I worked on, & here's the list; as you can see, mostly pkg-perl bugs ps: the how-can-i-help package is a nice tool for finding RC bugs in packages you care about. install it if you haven't so far!

Dominique Dumont: My activities during Perl/QA hackathon in Paris

Hello Last week-end, I ve participated Perl/QA hackathon in Paris. Here s a short summary of the main activities during this week-end. I was not in the best of shape due to a nasty (biological) bug that wore me down before the hackathon. First of all, I discussed with rjbs about the bunch of debian patches I ve written for Software::License. These patches (and hacks) are used in Debian to provide licenses summaries in Debian::Dpkg::Copyright model to help write Debian copyright files. License management is boring but necessary. cme and Software::License help in making this task slightly less boring. Ricardo kindly suggested some modifications and agreed to include my patches. I implemented these modifications directly during the hackathon. The other tasks during this week-end were (not necessarily in that order): Many thanks to FreeSide who sponsored my travel, to the hackathons organisers and to all the participants for their welcome. All the best

Cosimo Alfarano: Facebook provider for GNOME Online Accounts

Following Xavier's steps, last week a new patch set has been commited to GNOME Online Account master repo, this time to add support for Facebook client-side auth flow, which does not require secret keys to work.

This means that since GNOME 3.4 it will be possible to enable Facebook support at configure time (yep, by default it's still disabled. Distributions will explicitly need to enable it for now). Currently only chat is supported.


The steps to enable it are easy:
Use --enable-facebook at configure time and compile+install as usual.A default FB application id is used, so you don't need to provide it.
Using the freshly updated goa-daemon (use --replace in case you're unsure) select online accounts from the control panel, add a facebook account (which should be now possible to select, along with at Google and Windows live if you've enabled it) and follow the on-screen instruction.
You'll need to authenticate yourself against Facebook and authorize the GNOME application.
Once your account has been created, set your presence to Available using Empathy or gnome-shell.
Now chat with your Facebook buddies \o/

It requires empathy (>=3.3.2), telepathy-gabble (>= 0.15.0) and of course gnome-online-accounts (the soon soon to be released 3.4.0, or directly git master)

Thanks to Xavier who backported to 3.4 my patches, originally meant for 3.6, and to Collabora who allowed us to improve Gnome Online Accounts!

Julien Valroff: I am a Debian Developer!

A few months after starting the NM process, I have just been accepted as a Debian Developer. My account name is simply: julien I have been a Debian user for about 10 years now, and have begun contributing to Debian in 2005. I have then been accepted as a Debian Maintainer in 2007. This post is mainly to thank: Also thanks to all people who have already sent their congratulations, it makes me very proud!

Stefano Zacchiroli: mini debconf paris - success

I'm just back home after Paris mini-DebConf. I'm happy, excited, and exhausted almost as if it had been a full fledged DebConf. That's enough in my book to consider the event a complete success. As far as I know, it has been the first mini-DebConf held in Paris and about 150 people have come to attend the event from all over Europe. Off the top of my head I've met friends from at least: Spain, UK, France (obviously!), Italy, Germany, Austria, Switzerland, Greece. I'm still very much impressed by such a diverse attendance. Initially, I had planned the first "DPL strike" ever (i.e. not doing anything DPL-related) for the duration of the conference, in order to take part into the BSP. That agenda has been pretty much subverted by a last minute emergency, by chatting with loads of people, and by actually finalizing the Debian Sprint Program, which had been at the top of my Debian TODO list for quite a while now. Nonetheless, I've managed to advance a bit on a couple of RC bugs, which belong to the "annoying/pointless/but-still-valid" category. They are not solved yet, but I hope to have good news to share soon. Bottom line: I loved the event. and I've even managed to avoid getting killed by my (local) family for taking part in a Debian-weekend after an almost full week of Debian traveling, which is another success on its own right :-) Closing advice: beside some last minute legwork, I did essentially nothing to organize this mini-DebConf, your kudos should be better directed to Carl Chenet and Mehdi Dogguy for the organization. Other gifts such as bug fixes can be directed to the speakers, sponsors, and loads of other helpers from Debian France and not in particular Xavier Oswald, Valessio Brito, Tanguy Ortolo, Nattie Mayer-Hutchings, Luca Capello, Stephane Glondu, and others which surely I'm forgetting to mention here (sorry about that). Kudos folks ... let's do it again next year! (SCNR)

Sylvain Le Gall: OCaml cryptokit and Java PBEWithMD5AndDES

During one of my project I need to interact with Java cryptographic extension. Some data has been encrypted using PBEWithMD5AndDES. I need to access it from OCaml. I take a look at available cryptographic extension in the Debian project for OCaml: cryptgps and cryptokit. I choose cryptokit, because its author is well known: Xavier Leroy. This article was my starting point. Of course, I keep in mind that the reference is there and that there is a good article covering it. Here is the result in OCaml: 
 let decrypt passphrase salt ?(iterationCount=41) str =
   let key, iv =
     let rec hash_aux iter str =
       if iter > 0 then
         (* Rehash string *)
         hash_aux
           (iter - 1)
           (hash_string
              (Hash.md5 ())
              str)
       else
         (* Key = first 8 bytes of the MD5 hash *)
         String.sub str 0 8,
         (* IV = last 8 bytes of the MD5 hash *)
         String.sub str 8 8
     in
       (* Hash n times combination of passphrase and salt,
           return key and iv 
         *)
       hash_aux
         iterationCount
         (passphrase ^ salt)
   in
     transform_string
        (Cipher.des
           ~pad:Padding.length
           ~iv:iv
           key
           Cipher.Decrypt)
       str
The only missing information was the pad algorithm to use (Padding.length). For this piece of information, I need to browse the RSA documentation and test a little bit. Rewriting PBEWithMD5andDES is quite straightforward with cryptokit and OCaml. It takes 25 lines with C# and OCaml (only counting LoC, no comment, no empty constructor or declaration in C#). I was thinking that this task will require 2 or 3 days, but it has been done in 4 hours... Many thanks to cryptokit ;-)

Sylvain Le Gall: OCaml 3.12.0 is out: watch the movie

I have been quite busy the few last months. But anyway, I found time and solved various technical pitfalls to be able to bring you the first movie of the OCaml Meeting: Foreword by X. Leroy at OCaml Meeting 2010 (subtitle: OCaml 3.12.0 features presentation) In this video, Xavier Leroy told us about the features in OCaml 3.12.0. This version is now released so it is high time to release the matching movie. I will release other movies of the OCaml Meeting during August and will try to explain the various pitfalls I encounter -- and the OCaml solutions I use to solve them.

Raphaël Hertzog: Quick news: dpkg, collab-maint, alioth and the future

Dpkg got rid of Perl Let s start with the interesting part and the great news: dpkg 1.15.8 (to be uploaded soon) will no longer need perl! After my changes to rewrite update-alternatives in C, Guillem recently pushed the rewrite of dpkg-divert/mksplit in C. Please test it out (binary package for i386 or .dsc). This is rather exciting news for those who would like to use dpkg in embedded contexts. And it s great to see this completed in time for Squeeze. In Squeeze+1, we might go one step further and merge cdebconf, the C replacement for debconf. I got rid of some recurring administrative tasks I have been administrating the Alioth server since its inception (see the announce I sent in 2003) but I m no longer enjoying the day-to-day administrative work that it represents. That s why I just retired from the team. We recently recruited Tollef Fog Heen so the number of admins is still the same (that said, Alioth could benefit from some more help, if you re a DD and interested, drop a mail to admin@alioth.debian.org or come to #alioth). Same goes for the collab-maint project. I have dealt with hundreds of requests to add new contributors to the project since it s the central repository where all Debian developers have write access and where they put the VCS for their packages that do not belong to a more specialized team. The new administrator that will approve the requests is Xavier Oswald and he s doing the work under the umbrella of the New Maintainer s Front Desk. The future I will continue to spend the same amount of time on Debian, the time freed will quickly be reallocated to other Debian and free software related projects. In fact, I even anticipated a bit by launching Flattr FOSS last week but that s a relatively simple project. :-) The other projects that will never all fit in the freed time: I want to spend more time working on dpkg. I do plan to blog more often too, but I m sure you ll notice that yourself soon. I would like to see my Debian book translated into English (another post coming on the topic sometimes soon). In my dreams, I could even start yet another software project, I have some ideas that I really would like to see implemented but I don t see how that could fit in this year s planning unless I can convince someone else to implement them! Maybe I should blog about them. Flattr this Share/Bookmark 5 comments Support my work

Stefano Zacchiroli: camljava for recent JVMs

resurrecting CamlJava (testers welcome) CamlJava is a great project by almighty Xavier that bridges the OCaml and Java worlds via the respective C interfaces (Caml/C interface for OCaml and JNI for Java). Unfortunately, the last stable release was a bit out of date and seemed not to work with recent JDK (both in terms of buildability and of runtime correctness, i.e., segfaults). With the tremendous help of Gr goire Henry, I've managed to prepare a set of patches that enables to build (and use without segfaults ...) CamlJava with recent JVM: in particular it seems now to work with both Sun's JVM and OpenJDK. A Debian package has been prepared; while it gets processed by archive manager, you can get an equivalent unofficial package from my APT repo: 
    deb http://people.debian.org/~zack/debian zack-unstable/
    deb-src http://people.debian.org/~zack/debian zack-unstable/
Any form of testing is very welcome. In case you want to try O'Jacare on top of CamlJava however, you need to wait a bit more: Gr goire is working on it, but in the process he banged his head against bugs in both CamlP4 and CamlP5 (the only two available porting paths from the last stable release of O'Jacare) :-)
