Distributing iOS Apps Beyond the Limitations of Ad-Hoc Distribution As a developer, you’ve likely encountered situations where traditional ad-hoc distribution methods aren’t sufficient. Perhaps you’re working with a large organization that requires access to your app across multiple devices beyond the 100-device limit stipulated by Apple’s Ad-Hoc distribution policy. In this scenario, you may be wondering if there’s an alternative way to distribute your iOS app without relying on the App Store or exceeding the ad-hoc limit.

Understanding Reverse Geocoding on iOS: A Deep Dive Reverse geocoding is the process of determining a location’s geographic coordinates (latitude and longitude) based on information about that location. In this article, we’ll delve into how to perform reverse geocoding on an iPhone, exploring both Apple-provided solutions and external web services. Introduction When building an iOS app, you may encounter situations where you need to determine a user’s location or the location of a specific point of interest.

How to make a line plot in R with time on x-axis ============================================= In this article, we will explore how to create a line plot using the ggplot2 package in R, where the x-axis represents time. We’ll go through the process of data preparation, filtering out unwanted columns, and customizing the plot’s appearance. Introduction to Time-Based Plots in R R provides several packages for creating plots, including ggplot2, which is a powerful tool for creating beautiful and informative visualizations.

Using the Split Function to Display Each Value in a Separate Row In this article, we will explore how to use the Split function in T-SQL to split a comma-separated value into separate rows. We’ll start with an explanation of the problem and then dive into the solution. Understanding the Problem Suppose you have a table with two columns: ID and [Char]. The [Char] column contains a comma-separated list of values, such as 'A,B', 'A', or 'B,C'.

Introduction to 3D Histograms with Plotly in R In this article, we’ll explore the process of creating a 3D histogram using the popular data visualization library, Plotly, within R. A 3D histogram is a graphical representation that combines two variables into three dimensions, providing a more nuanced understanding of their relationships. Background and Requirements To create a 3D histogram with Plotly in R, we’ll need to: Install and load the required libraries: plotly and viridisLite.

Creating a View of a Query Generated by Another Dynamic (Meta) Query In this article, we’ll explore how to create a view of a query generated by another dynamic (meta) query. We’ll delve into the details of creating temporary views in PostgreSQL and provide examples to illustrate the concepts. Introduction Temporary views are a powerful tool in PostgreSQL that allows you to create a view based on a query, which can be used to simplify complex queries or improve performance.

Understanding the OPENROWSET Function in VBA ADO Queries As a developer, we often find ourselves working with data from various sources, including Microsoft Excel files. In this article, we’ll delve into the world of VBA ADO queries and explore how to use the OPENROWSET function to connect to an external Excel file. What is OPENROWSET? OPENROWSET is a Microsoft SQL Server method (i.e., TSQL) that allows us to access data from non-SQL databases, such as Microsoft Excel files.

Understanding Oracle 12c and Duplicate Records Selection As a technical blogger, it’s essential to explore the intricacies of popular databases like Oracle. In this article, we’ll delve into Oracle 12c and focus on selecting records that have sequences. We’ll break down the problem statement, explore possible solutions, and examine an example use case. Problem Statement We’re dealing with a table named t that contains three columns: employee_id, unique_emp_id, and emp_uid. The objective is to identify all duplicate records where at least one value in the unique_emp_id column resembles a specific pattern (%-%) and another value does not.

Understanding SQL Group Functions and Error Handling Introduction SQL, or Structured Query Language, is a programming language designed for managing and manipulating data stored in relational database management systems. One common mistake made by developers when using group functions like AVG is the misuse of the * operator, which can lead to an “invalid group function” error. In this article, we’ll explore what causes these errors, how to fix them, and provide examples with explanations to help you better understand SQL and avoid similar issues in your own code.

Creating an Analog Clock with Custom Background and Hands in iOS Creating an analog clock application for iPhone involves several steps, including designing a custom background image, creating images for each of the hands (seconds, minutes, hours), and implementing a method to rotate these views every second. Understanding Analog Clock Components An analog clock consists of three main components: the background, hour hands, and minute hands. The hour hand is typically thicker than the minute hand and appears at the 12 o’clock mark.
