Presented at Confoo (Montreal, Cananda)
Let's spend some time seeing how easy it can be to set up Mocha and Chai, a testing framework for JavaScript/CoffeeScript, in your application. We'll learn how to test that our jQuery or Backbone code is doing what it supposed to. It's really not as hard as you think it might be.
Testing your JavaScript and/or CofffeeScript applications is not nearly as difficult as you think. Learn how to quickly setup Jasmine in your Rails application and start testing your *script applications now!
Presented at Confoo (Montreal, Canada) on 3/1/2013
In this talk I’ll show you how to build your application and get a working, well tested, and useable API in the process, with almost no extra overhead. I’ll also show you how to do it without making your controllers a mess of respond_to blocks. If anything, you’re controllers will become cleaner and leaner.
Elixir is great for web servers and embedded devices, but is there anything else it’s good for?
Yes! Elixir is also great at being a multiplayer game server.
We’ll take a look through some existing applications that use Elixir as a multiplayer backend server, ExVenture and Kalevala.
See how they’re architected to be full of state and event driven to handle thousands of users.

DC |> Elixir Meetup - Going off the Rails into Elixir - Dan IvovichSmartLogic
Presentation from DC |> Elixir, March 19, 2019. Covered transitioning from Ruby on Rails to Elixir and Phoenix, and why developers want to make that transition, and why management should be supportive of that transition.
Monitoring Your Elixir Application with PrometheusSmartLogic
Get under the hood of your application, with metrics! What is your slowest external call? What are your total daily interactions? Find out with Prometheus!
We’ll use Prometheus and Grafana to give us insights into your application. Prometheus will gather time series metrics, and Grafana will give a powerful display of them.
We’ll cover how to add instrumentation through the lens of a real-world application.
Finally, we'll get alerted about key metrics via the Prometheus AlertManager.
You have an application that works well on a single node, and you’ve heard that Erlang lets you scale out in a cluster. How do you go about doing that?
We’ll walk through the steps I took to turn ExVenture (a multiplayer game server) into a distributed application.
Starting with connecting nodes in development and production, to picking a cluster leader via the Raft protocol, and dealing with process groups to fan calls throughout the cluster.
Finally we’ll see some of the hurdles I encountered when spanning multiple nodes.
SmartLogic's Eric Oestrich discusses Kubernetes at Baltimore Innovation Week. Kubernetes is a webscale cluster manager. By the end of the talk we will have a Rails application hosted inside of Kubernetes, Google's new cluster manager.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Editor's Notes
◦ Hello my name is Ryan DeStefano, I am a designer at SmartLogic. We build web and mobile apps here in Baltimore. ◦ today I am going to talk about CSS preprocessors and how they can help you write better style sheets.
▪ write style sheets that are less frustrating ▪ don ’t repeat yourself ▪ write less code, more importantly write smarter code
• inability to nest code - requires writing lengthy selectors takes too much time - don ’t waste your time catering to CSS’s inefficiencies makes navigating CSS files cumbersome
inability to reuse code - this is the big one ◦ hinders maintainability - if you want to change something, such as a color, or a font size, or a width, you have to make sure you change it everywhere it is used
▪ when you are forced to repeat yourself you are writing less maintainable code. ◦ writing CSS requires you to repeat yourself quite a bit. ▪ it would be really nice if I could write less CSS myself and make the computer write the rest for me. • inability to reuse code - this is the big one ◦ hinders maintainability - if you want to change something, such as a color, or a font size, or a width, you have to make sure you change it everywhere it is used ◦ takes too much time - don ’t waste your time catering to CSS’s inefficiencies ▪ maybe I ’m not sure if I really want to make a change or not - CSS requires a lot of work just to see what something would look like.
◦ Browsers only understand CSS, so you are forced to communicate in CSS. Unless you use a translator - a processor that converts what you write into CSS. Preprocessor translates whatever you write into CSS so that the browser can understand it. ◦ Preprocessed languages, such as Sass, compile to normal CSS. You can write in any format you like, as long as the preprocessor understands what you are writing and can compile it to CSS. Everything you write is converted to plain CSS.
what preprocessors are available? ▪ several, Sass and LESS are most popular, there are others such as stylus ▪ I will be using Sass in this presentation, in particular the form of Sass known as SCSS. I ’ve selected this because it’s the most similar to plain CSS. It is also the one I use. ▪ The syntax of each preprocessor varies. Some are move removed from CSS, such as Stylus which does not use braces, colons, or semicolons. There is an alternate form of Sass which also relies on significant whitespace. The most popular preprocessed languages have syntaxes that are similar to CSS. This allows people who know CSS to learn the preprocessed language relatively easily. In Sass, for example, all valid CSS is also valid Sass. ◦ Being freed from the constraint of only writing code that the browser understands allows for additions to CSS. For example, CSS does not handle variables - but you can use variables in a preprocessed language, because the preprocessor understands how to compile the SCSS to CSS.
Parent reference
same for pseudo-selectors
◦ variables ▪ most simple way to reuse code ▪ perfect for colors, font sizes, width, heights, etc.. - anything that can be reused or changed
Using variables in this way can allow you to have a lot of control over the way a site looks. You can build an admin-panel of sorts that controls colors, sizes, etc.. all from one place. This can be can be a dedicated .scss file that is then imported into all other .scss files in a project.
▪ Same thing with mixins - consistency throughout your site. If you change something, you should be changing all instance of that thing. The ‘admin panel’ makes this super easy.
arguments / parameters
Operations also allow for increased consistency. For example, setting a base font-size and making larger and smaller sizes as percentages of the base. Use variables to describe these.
◦ Using variables and mixins is not only a matter of convenience/laziness. It is also less error-prone. For example, a site may use a particular shade of blue throughout. If I decide that the blue is too light, it could be difficult and tedious for me to switch to a darker shade. The color may be used across several CSS files, so not only would it take me a bit of time to update every instance of the color blue, but it ’s also possible that I could miss one. Defining the color with a variable allows me to use a darker shade of blue by changing only one line of code. This is way faster and I know that I’m not going to be accidentally missing and instance of the colors I want to change. ◦ What else can preprocessors do?
◦ When can we expect CSS to evolve? - don ’t get your hopes up. ▪ no plans in the near future - Improvements to CSS do not happen frequently. CSS is progressing more slowly that would be preferable to web developers and designers. Preprocessors help fill in where CSS is lacking. ▪ even if CSS spec does catch up, when will the browsers implement these changes? ▪ IE won ’t be quick and users will still be using older versions on IE. ◦ We need improvements now!
◦ they are for anyone who has a good understanding of CSS ◦ They are great for designers who already know CSS, because they follow the same syntax as CSS, so you don ’t have to worry about learning a completely different language. All CSS is valid Sass, so you can use as much or as little of the additional features. ◦ Preprocessors are great for developers because they introduce concepts such as variables and operations, which you already know, and make CSS seem more like a true programming language. ◦ who are they not for? ▪ They are not for people who don ’t already know CSS. You should learn CSS first so that you can know if the compiled CSS is any good. ▪ You would need to know CSS so that you can troubleshoot any issues you may run into, such as viewing the outputted CSS in the inspector. ▪ Preprocessors are not a shortcut or an excuse not to learn CSS.
