Exercises in .NET with Andras Nemes Introduction In the previous post we went through our strategy to save the longitude-latitude coordinates in DynamoDb for our geo-spatial queries later on. We said that we would save the records in DynamoDb in a way so that it fits queries according to a library designed by AWS which in turn uses a geo-library from Google. In this post we’ll finally see some action. We’re ready to format an upload the IP range to DynamoDb. Actually we’ll show the techniques using only a small subset of the MaxMind raw data source.

A Complete Guide to Grid CSS Grid Layout is the most powerful layout system available in CSS. It is a 2-dimensional system, meaning it can handle both columns and rows, unlike flexbox which is largely a 1-dimensional system. You work with Grid Layout by applying CSS rules both to a parent element (which becomes the Grid Container) and to that element’s children (which become Grid Items). Get the poster! Reference this guide a lot? Manual Stability: 3 - Stable To use the HTTP server and client one must require('http'). The HTTP interfaces in Node are designed to support many features of the protocol which have been traditionally difficult to use. In particular, large, possibly chunk-encoded, messages.

Meteor.js JavaScript Framework: Why Meteor Rocks! Exclusive offer: get 50% off this eBook here Getting Started with Meteor.js JavaScript Framework — Save 50% Develop modern web applications in Meteor, one of the hottest new JavaScript platforms with this book and ebook. by Isaac Strack | February 2013 | Open Source Web Development Meteor is a disruptive (in a good way!) technology. leak-finder-for-javascript - Tool for finding memory leaks in JavaScript programs. In JavaScript you cannot have "memory leaks" in the traditional sense, but you can have objects which are unintentionally kept alive and which in turn keep alive other objects, e.g., large parts of DOM. Leak Finder for JavaScript works against the Developer tools remote inspecting protocol of Chrome, retrieves heap snapshots, and detects objects which are "memory leaks" according to a given leak definition. The default configuration of the tool detects goog.Disposable objects which were not dispose()d. goog.EventTarget is a subclass of goog.Disposable, and if an EventTarget is not disposed, event listeners are not discarded properly, and event listeners in turn keep DOM objects alive. It's possible to configure the tool to detect other similar misuses. Resources:

Using Amazon DynamoDb with the AWS .NET API Part 5: updating and deleting records Introduction In the previous post we saw how to insert records into an Amazon DynamoDb table. We looked at two distinct programmatic ways to build our objects to be inserted: the loosely typed Document model and the strongly typed, more object oriented Data model. In this post we’ll see how to update and delete records using the two models. As a reminder we inserted the following records into our DynamoDb People table in the previous post:

Building a hexagonal grid using CSS grid - I've been chasing the idea of using (abusing?) CSS grid to build a interconnected hexagonal grid, where each hexagon fits together seamlessly. An example of this would be a lot of tabletop war games, some board games (Settlers of Catan, for instance), and some computer games (I used to play The Battle for Wesnoth, it uses a system like this). Here's the list of requirements I had going into this: How To Use MySQL With Meteor ⚙ Co The problem with Meteor, for me, isn’t really with Meteor at all. It's with MongoDB, which is bundled with Meteor. I do like the fact that I don't need to change the schema when I make changes to the DB or the fact that I can insert arbitrary data and even create real objects without resorting to ORM. But all of this doesn't really compensate for the fact that MongoDB is so limited compared to modern SQL databases.
