This document discusses code smells in programming. It defines code smells as surface indications that usually correspond to deeper problems in a system. Common code smells include duplicate code, long methods, large classes, and long parameter lists. The document provides examples of each code smell and recommends solutions such as extracting duplicate code into new methods, breaking long methods into smaller subroutines, breaking large classes into separate components, and removing unnecessary parameters. It also recommends tools programmers can use to detect code smells like Flog, Flay, Reek, and Brakeman in Ruby code.
It's easy to look at where you are and where you want to be and think, “I’ll never get there” and plateau with your current skill set.
Maybe you’re a developer who is looking to level up their career. Maybe you’re someone who wants to break into a development career for the first time.
Wherever you’re at, I want to teach you the same methods I use every single day to keep my skills sharp and to keep myself connected to interesting and rewarding projects and relationships.

Development and Deployment: The Human FactorBoris Adryan
Thingmonk 2017: End-to-end IoT solutions are often highly integrated. Even small changes to the UX of a product can have profound impact on hardware requirements, while physical constraints such as battery capacity can dictate software architecture. A holistic understanding of IoT is key to efficient implementation, the “T-shaped engineer” the star in every development team. Contrast this to intellectual silos and matrix organisation, and you may see why especially large companies fail to move quickly into IoT. Similar issues strike the application of IoT. Deploying a solution in the enterprise is just a cost factor if processes are not adjusted to leverage the connected device and its data. However, changes in process often affect companies across their entire organisational structure. This can require a change of mindsets, making the success of an IoT solution depending on the human factor.

Comprehensive approach to delivering great developer products
Ryohei Miyota / LINE Corpration
While LINE is the most popular consumer messaging application in Japan, we are not as popular a developer product as we are as a consumer product. Although we always recognized the strategical importance of opening our platform, we have not opened our platform aggressively until recently as can be seen by the notable fact that we still do not have a developer relations team. Why? There were scalability issues unique to a company who rapidly grew by aggressively releasing consumer products. In this talk, we discuss challenges we faced in such areas as engineering itself and approaches to engineering, and describe our recent efforts to overcome these problems. Furthermore, we show our prospect of developer advocacy with platforms that have been closed but might open in the future.

From Content Strategy to Drupal Site Building - Connecting the dotsRonald Ashri
Content strategy is, undoubtedly, a hot topic these days. A lot is being said that spans the range from concerns regarding the ability to display content on any device to the ability to drive engagement and increase traffic through better content creation and social media strategies. In this presentation we will connect the dots between these issues and practical Drupal site-building concerns with tools that are readily available now.
We will show, through specific examples and references to available modules, how different approaches to content strategy can be practically implemented on Drupal sites. The aim is to equip Drupal site-builders with a handy toolkit that will allow them to both implement a content strategy for their sites as well as better exchange information with content strategists.
The examples will include:
- Different approaches to building content types so as to empower content creators to create a range of different structures.
- Best practices in using vocabularies (fixed, open, user-generated, moderated, etc) or where alternative categorization methods may be relevant.
We will also discuss:
- Editorial calendars and scheduling.
- The true benefit of workflows (and how, sometimes, they can be a disadvantage).
- Analytics and how the ability to measure the effects of any strategy is as important as defining the strategy itself.
Attendees will go away with practical examples and techniques that they can apply to their sites as well as a better understanding of what content strategy really is and how they can use it to improve their sites.
The examples are a result of our own experiences in helping both clients develop their content strategy as well as applying it on italymagazine.com, an in-house product of ours. We grew italymagazine.com to a relevant online digital brand with a strong community by expressing our content strategy ideas through the tools that Drupal 7 made available to us. The resulting ~250% increase in traffic over 3 months is a testament to both the value of a content strategy as well as the power of Drupal to allow you to flexibly and iteratively support it.
In this update of his past presentations on Mobile Eating the World -- delivered most recently at The Guardian's Changing Media Summit -- a16z’s Benedict Evans takes us through how technology is universal through mobile. How mobile is not a subset of the internet anymore. And how mobile (and accompanying trends of cloud and AI) is also driving new productivity tools.
In fact, mobile -- which encompasses everything from drones to cars -- is everything.

10 of the Biggest Stories in TechnologyBrett Cotham
October was filled a a number of great technology breakthroughs. While it is impossible to list all of the new advancements, I would like to share my favorites. Here are 10 of the biggest stories in technology throughout the month of October.
Let Non-Developers Develop your Site. Manu RaivioFuture Insights
FOWA London 2015
Testing different versions of your site can be hugely distracting; it’s both trivial and non-trivial, and terribly time-consuming. Layer-based iterative development can help by effectuating all changes in the user’s browser instead of the site’s backend. Manu will present this new approach to developing the best performing version of a site using the Frosmo javascript tag and SaaS platform. Together they can save time and let those most interested in the results be in charge of the tests, without putting your site at risk.
Keynote presented at SDD (12th May 2015)
Somewhere in the heart of a development process, essential to the very being of a product's existence, are the people who write, consider and wrestle with code. What motivates and demotivates them? What are the intellectual challenges and rewards? What are the skills they have and need and cognitive biases and environment they work with and against?
This talk by the editor of 97 Things Every Programmer Should Know considers the act of programming and those who do it and want to get better at it, from the perspective of development process to craft, from architecture to code.
Hadoop, Spark or even Clojure? Those may be out-dated. JSON-FP brings in a new programming paradigm that is fun and inspiring. If you need to query objects in distributed / heterogeneous data repositories, you might want to try out JSON-FP.
Python for R developers and data scientistsLambda Tree
This is an introductory talk aimed at data scientists who are well versed with R but would like to work with Python as well. I will cover common workflows in R and how they translate into Python. No Python experience necessary.
Stemming from the rapid prototyping maker movement, technology has taken a huge leap forward to begin true integrations with the human body. From controlling physical hardware through muscle tension armbands, to heartbeat monitoring wristbands to uniquely identify a person, this year is set to produce the first in a long line of technology leading the way to truly embedded technology. We'll explore this movement and see where the future of technology integrations is leading us as a species.

Reducing Resistance: Deployment as SurfaceJeffrey Hulten
This is the talk I gave at Agile2014 discussing how to think about your deployment choices as surfaces on an airplane. Paper airplanes were thrown as a part of this talk.
Knowledge and identification of Malware binaries is a crucial part of detection and incident response. There was a time when using MD5s was sufficient to ID binaries. The reverse engineering analysis conducted once would be useful anytime that same MD5 hash was seen again. This has rapidly changed in recent years. Polymorphic samples of the same specimen change the file hash (MD5, SHAx etc) without much effort by the attacker. Also, cyber criminals and advanced adversaries reuse their codebase to create newer versions of their malware, but changes in the file hash disallow any opportunity to connect and leverage previous analyses of similar samples by defenders. This gives them an asymmetric advantage.
In recent years, there has been research into “similarity metrics”― methods that can identify whether, or to what degree, two malware binaries are similar to each other. Imphash, ssdeep and sdhash are examples of such techniques. In this talk, Bhavna will review which of these techniques is more suitable for evaluating similarities in code for APT related samples. This presentation will take a data analytics approach. We will look at binary samples from APT events from Jan- Mar 2015 and create clusters of similar binaries based on each of the three similarity metrics under consideration. We will then evaluate the accuracy of the clusters and examine their implications on the effectiveness of each technique in identifying provenance of an APT related binary. This can aid Incident responders in connecting otherwise disparate infections in their environment to a single threat group and apply past analyses of the abilities and motivations of that adversary to conduct more effective response.

Switching horses midstream - From Waterfall to AgileDoc Norton
You’ve been working for several months on a key software initiative for the company and leadership has decided they want it faster than projected, so the team has been told they’re getting “the agile” installed next week.
“Great.”, you think, “Right in the middle of the project. Nothing like changing horses in midstream. One way or another, this will go swimmingly.”
Sarcasm and puns aside, you’ve got a point. It isn’t easy to switch methodologies in the middle of a project. Doc shares some stories from his own experiences helping teams make this change and provides a few pointers that can help you do the same.
While this talk is focused on testing, it involves the whole team, as agile methods usually do.
The audience here were design & digital agencies.
I shared what I learned about UX.
UX is not UI. UX is about empathy. UX is ideating, iterating and collaborating for solutions.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
