Core Data with multiple managed object contextsMatthew Morey
When using Core Data for persisting app data multiple managed object contexts (MOC) are often required to avoid blocking UI. Typically you would create a background MOC and listen for changes on the main MOC, merging changes as necessary. With iOS 5, MOCs now have parent context and the ability to set concurrency types. These new features greatly simplify dealing with Core Data on background queues. During this presentation Matt will cover the pros and cons of this new method of dealing with Core Data.
This presentation educate you about how to create table using Python MySQL with example syntax and Creating a table in MySQL using python.

Learn how to analyze, debug, and squeeze every last bit of performance out of Core Data. The standard Core Data implementation is very powerful and flexible but lacks performance. In this advanced session we will cover various performance analysis tools, model optimization, and various high performance concurrency models. This is an advanced discussion that assumes you have used Core Data before.
This presentation educates you about Python MySQL - Database Connection, Python MySQL - Database Connection, Establishing connection with MySQL using python with sample program.

C* Summit EU 2013: Cassandra Made Simple with CQL Drivers and DevCenter DataStax Academy
Speakers: Michaël Figuiere, Software Engineer at DataStax & Alex Popescu, Senior Product Manager at DataStax
Video: http://www.youtube.com/watch?v=hK2dXLiYVMI&list=PLqcm6qE9lgKLoYaakl3YwIWP4hmGsHm5e&index=11
Is Cassandra too complex for newcomers? Besides the many improvements that have made their way into C* to dramatically simplify it and the finalized Cassandra Query Language, the SQL-like query language that should look familiar, new drivers have been created with a modern and efficient API. Last, but not least, DataStax is introducing *today* DevCenter 1.0, an IDE whose goal is to simplify developer's workflow even further and to improve their productivity. This presentation will show you how putting to work the new drivers and DevCenter can make your daily life with Cassandra nicer!

Ten useful JavaScript tips & best practicesAnkit Rastogi
In this presentation there are ten useful JavaScript techniques which can be included in your application easily with less friction along with some AngularJs tips and best practices as a bonus. These tips and best practices are accompanied by examples & will cover script loading, design pattern, performance optimization and other areas.
Since best practices are very subjective topics, proper benchmarking needs to be done.
jQuery is so easy to write and therefore so easy to write poor code also. As coders are we sure that what we write can easily be digested by the web page? Lets go and see how we can easily improve performance with same code with different approach.

Presentation given by Ron Northrip (@ronnorthrip) Jan 23 at the Kentucky JavaScript Users Group meeting discussing the history and trending topics in JavaScript.
Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.

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.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Are you looking to streamline your workflows and boost your projects’ efficiency? Do you find yourself searching for ways to add flexibility and control over your FME workflows? If so, you’re in the right place.
Join us for an insightful dive into the world of FME parameters, a critical element in optimizing workflow efficiency. This webinar marks the beginning of our three-part “Essentials of Automation” series. This first webinar is designed to equip you with the knowledge and skills to utilize parameters effectively: enhancing the flexibility, maintainability, and user control of your FME projects.
Here’s what you’ll gain:
- Essentials of FME Parameters: Understand the pivotal role of parameters, including Reader/Writer, Transformer, User, and FME Flow categories. Discover how they are the key to unlocking automation and optimization within your workflows.
- Practical Applications in FME Form: Delve into key user parameter types including choice, connections, and file URLs. Allow users to control how a workflow runs, making your workflows more reusable. Learn to import values and deliver the best user experience for your workflows while enhancing accuracy.
- Optimization Strategies in FME Flow: Explore the creation and strategic deployment of parameters in FME Flow, including the use of deployment and geometry parameters, to maximize workflow efficiency.
- Pro Tips for Success: Gain insights on parameterizing connections and leveraging new features like Conditional Visibility for clarity and simplicity.
We’ll wrap up with a glimpse into future webinars, followed by a Q&A session to address your specific questions surrounding this topic.
Don’t miss this opportunity to elevate your FME expertise and drive your projects to new heights of efficiency.
4. Better Tests
● _.isNaN() - returns false with undefined
● _.isEqual() - full deep-compare, very
efficient
● Standard form - _.isFunction, _.
isString, _.isUndefined.
5. Extend for Mixins
_.extend(object, mixins)
● Works on any Javascript object
● Mixins are just standard JS objects too
{
addon_function: function()....
another_addon: function() ...
}
6. bind and bindAll
bind makes 'this' useful again
_.bind(function, context, [*args])
Returns a function that has a consistent 'this'
context.
_.bindAll(object) will bind all object's
properties with object as the context
7. Chain, Tap and Value
_.chain(value) returns a wrapped value,
which will stay wrapped until _.value() is
called
_([42, 43]).chain()
.first() // 42
.take(function(val) { return val * 2 }) // 42 * 2
.value() // 84
_.tap() let's you temporarily unwrap the value
inside the chain
8. So Much More
● Safer keys, values, lastIndexOf,
hasOwnProperty
● Array math (union, difference, sorting)
● Lightweight Templating
● All Under 4kb
9. Backbone Models
Backbone Models hold JSON data, typically
fetched from an external REST API
Backbone Models are defined with
Underscore's extend method
Backbone.Model.extend({
... model definition ...
});
10. Defaults
Backbone Models can define defaults which it
also borrows from Underscore
var Meal = Backbone.Model.extend({
defaults: {
"appetizer": "caesar salad",
"entree": "ravioli",
"dessert": "cheesecake"
}
});
11. fetch/save
Calling fetch() on a Backbone Model is
analogous to a "GET" of that resource.
Calling save() is analogous to a "PUT"
model.fetch();
// make changes to model data
model.save();
12. Backbone.sync
All I/O on Backbone Models is done with
Backbone.sync
By default, Backbone.sync implements it's
CRUD methods on an AJAX backend.
There exist alternate implementations, such as
backbone.localStorage and backbone.
mongodb
