Social Media Research Toolkit

Social Media Research Toolkita list of 50+ social media research tools curated by researchers at the Social Media Lab at Ted Rogers School of Management, Ryerson University. The kit features tools that have been used in peer-reviewed academic studies. Many tools are free to use and require little or no programming. Some are simple data collectors such as tweepy, a Python library for collecting Tweets, and others are a bit more robust, such as Netlytic, a multi-platform (Twitter, Facebook, and Instagram) data collector and analyzer, developed by our lab. All of the tools are confirmed available and operational.

GitHub starts the Open Source Guides

GitHub blog is “Announcing Open Source Guides“:

we’re launching the Open Source Guides, a collection of resources for individuals, communities, and companies who want to learn how to run and contribute to open source.

[…]

Open Source Guides are a series of short, approachable guides to help you participate more effectively in open source, whether it’s:

  • Finding users for your project
  • Making your first contribution
  • Managing large open source communities
  • Improving the workflow of your project

These guides aim to reflect the voice of the community and their years of wisdom and practice. We’ve focused on the topics we’ve heard about most, and curated stories from open source contributors across the web.

I think it’s a great idea and I really like the execution too.  Most of what I know about Open Source comes from years of participation, and from reading old books, manuals and licenses – not something that is easy to share with people who are just getting their feet wet.

GitHub’s Open Source Guides are very simple, concise and specific.  And they cover a variety of subjects, not just the legal or technical side of things, but also communications, support, marketing, etc.

Fixing outdated Let’s Encrypt (zope.interface error)

I’ve started using Let’s Encrypt for the SSL certificates a while back.  I installed it on all the web servers, irrelevant of the need for SSL, just to have it there, when I need it (thanks to this Ansible role).  One of those old web servers needed an SSL certificate recently, so I thought it’d be no problem to generate one.

But I was wrong. The letsencrypt-auto tool got outdated and was failing to execute, throwing some Python exception about missing zope.interface module.  A quick Google search brought this StackOverflow discussion, with the exact issue I was having.

Traceback (most recent call last):
  File "/root/.local/share/letsencrypt/bin/letsencrypt", line 7, in <module>
    from certbot.main import main
  File "/root/.local/share/letsencrypt/local/lib/python2.7/dist-packages/certbot/main.py", line 12, in <module>
    import zope.component
  File "/root/.local/share/letsencrypt/local/lib/python2.7/dist-packages/zope/component/__init__.py", line 16, in <module>
    from zope.interface import Interface
ImportError: No module named interface

However, the solution didn’t fix the problem for me:

unset PYTHON_INSTALL_LAYOUT
/opt/letsencrypt/letsencrypt-auto -v

Even pulling the updated version from the GitHub repository didn’t solve it.

After poking around for a while more, I found this bug report from the last year, which solved my problem.

I recommend:

  1. Running rm -rf /root/.local/share/letsencrypt. This removes your installation of letsencrypt, but keeps all configuration files, certificates, logs, etc.
  2. Make sure you have an up to date copy of letsencrypt-auto. It can be found here.
  3. Run letsencrypt-auto again.

If you get the same behavior, you can try installing zope.interface manually by running:

/root/.local/share/letsencrypt/bin/pip install zope.interface

Hopefully, next time I’ll remember to search my blog’s archives …

Morphos – morphological solution in PHP for English and Russian

If you ever had to deal with morphology in English, you probably found one or two libraries to help you out.  But if you had to do that for Russian, than I’m sure you are missing a few hairs, and the ones that you still have are grayer than they used to be.  I’ve got some good news for you though, now there is Morphos (GitHub repository).

Morphos is a morphological solution written completely in the PHP language. Supports Russian and English. Provides classes to decline First/Middle/Last names/nouns and generate cardinal numerals.

Just look at this beauty!

var_dump($dec->getForms($user_name, $dec->detectGender($user_name)));
/* Will produce something like
  array(6) {
    ["nominativus"]=>
    string(8) "Иван"
    ["genetivus"]=>
    string(10) "Ивана"
    ["dativus"]=>
    string(10) "Ивану"
    ["accusative"]=>
    string(10) "Ивана"
    ["ablativus"]=>
    string(12) "Иваном"
    ["praepositionalis"]=>
    string(15) "об Иване"
  }
*/

Just this alone can make user interfaces and emails so much better.  But there is more to it than that.

Vim setup for PHP development

Robert Basic shares his “current Vim setup for PHP development“.  He shows how setup the Gutentags plugin, jump to definitions with CtrlP plugin, display of the current file and method in the status line, add support for PHP namespaces, improve linting with Asynchronous Lint Engine, and add support for PHPStan.

Incident pit

I came across the Wikipedia page for incident pit, which was a concept derived from analyzing multiple incident reports in diving:

The diagram shown is something that has evolved from studying many incident reports. It is important to realize that the shape of the “Pit” is in no way connected with the depth of water and that all stages can occur in very shallow water or even on the surface.

The basic concept is that as an incident develops it becomes progressively harder to extract yourself or your companion from a worsening situation. In other words the farther you become “dragged” into the pit the steeper the sides become and a return to the “normal” situation is correspondingly more difficult.

Underwater swimming may be considered to be an activity where, due to the environment and equipment plus human nature, there is a continuing process of minor incidents – illustrated by the top area of the pit.

When one of these minor incidents becomes difficult to cope with, or is further complicated by other problems usually arriving all at the same time, the situation tends to become an emergency and the first feelings of fear begin to appear – illustrated by the next layer of the pit. If the emergency is not controlled at this early stage then panic, the diver’s worst enemy, leads to almost total lack of control and the emergency becomes a serious problem – illustrated by the third layer of the pit. Progression through to the final stage of the pit from the panic situation is usually very rapid and extremely difficult to reverse and a fatality may be inevitable – illustrated by the final black stage of the pit.

The time for an incident to evolve in this way can be as short as 30 seconds or less, illustrated by the straight line passing directly through all the stages in the centre of the pit, or it may be more a slower process building up over a period of one minute or more [maybe a week!] – illustrated by the curving lines running from the [top] extremities of the pit. In this later case it represents the slowly evolving incident when the diver or group may not be aware that a serious situation is in fact developing. Between 30 seconds and about 1 minute is representative of the time required to take the necessary decisions and actions when it becomes obvious that an incident is about to happen.

The final conclusion is simple: never allow incidents to develop beyond the top normal layer of activity. If you find yourself being drawn into the second stage – the emergency – then use all of your training skill and experience to extract yourself and your companions from the pit before the sides become too steep!

I don’t think is applicable to diving only.  Similar incident pits exist in other areas of human activity (technology, business, politics, healthcare, and others come to mind) which involve crisis management.  The circumstances and the time frames might be slightly different, but overall, I think, it’s pretty similar.

 

 

GitHub to MySQL

GitHub to MySQL is a handy little app in PHP that pulls labels, milestones and issues from GitHub into your local MySQL database.  This is useful for analysis and backup purposes.

There are a few example queries provided that show issues vs. pull requests, average number of days to merge a pull request over the past weeks, average number of pull requests open every day, and total number of issues.

I think this tool can be easily extended to pull other information from GitHub, such as release notes, projects, web hooks.  Also, if you are using multiple version control services, such as BitBucket and GitLab, extending this tool can help with merging data from multiple sources and cross-referencing it with the company internal tools (bug trackers, support ticketing systems, CRM, etc).

This is not something I’ll be doing now, but I’m sure the future is not too far away.

PHP overwrite of built-in constants (true is false)

Here is a scary thing I picked up on Reddit PHP:

<?php
use const true as false;
if (false) {
    echo "uh-oh";
}

Until PHP 5.6 this was throwing a parse error, but from then on – it’s just fine.  Scary, right?

The comments on the Reddit thread are quite helpful.  Technically, this is not overwriting (shadowing?) since the original constant is still available:

<?php
use const true as false;
if (\false) {
    echo "uh-oh";
}

If you are a fan of nightmares, there is also this link, which will shake your religious beliefs …

i3 – tiling window manager

In the last few days my attention was unfairly distributed between a whole lot of tasks.  The fragmentation and constant context switching affected my productivity, so I briefly revisited my toolbox setup, in hopes to find something that I didn’t know about, forgot about, or have greatly underutilized.

One of the things that came (again) on my radar was terminal multiplexer tmux.  I’ve blogged about it before.  I used it for a while, but at some point, it faded away from my daily routine.  The two most useful features of tmux are:

  1. Persistent sessions, where you can work on a remote machine, detach your terminal, disconnect from the machine entirely, and then, at some point later, connect again and continue from where you left off.  With simpler workloads and reliable Internet connection, this became less useful to me.  When I do need this functionality, I use screen, which is more often installed on the machines that I work with.
  2. Terminal multiplexer, where you can split your terminal screen into a number of panels and work with each one like it’s a separate terminal.  This is still useful, but can be done by a number of different tools these days.  I use Terminator, which supports both horizontal and vertical screen split.  Terminology is another option from a choice of many.

I thought, let me find something that people who used tmux have moved on to.  That search led me, among other things, to “ditching tmux” thread on HackerNews, where in the comments a few people were talking about i3 tiling window manager.
