How to Get Your Twitter Follower Number in Plain Text

It’s easy to use a service like TwitterCounter.com to get a little chicklet button of your Twitter follower number. If you have that number in plain text though, then you can style and integrate it into your site much more attractively. In this post, I’ll show you how to get it.

You can see the end result in the top right of Tiny Buddha, a site I recently coded using Chameleon (Though this will work on any WordPress theme!)

And you can download the completed code here.
Quick Overview

To do this, we will create 3 functions, to:

1. Get the follower count from Twitter, and save it to your database.
2. Retrieve that count whenever you need it.
3. Update the count automatically every hour.

We add in the extra steps of saving to your database and updating because on a busy site, Twitter will cut you off for pestering their servers too much.

10 Data Points: Information and Analytics at Work

The New Intelligent Enterprise inquiry is all about the intensifying wave of data that organizations are facing, and its implications for managers. Companies are becoming data driven in ways that are new, raw and — in many cases — untested. And now so are we: We’re trying something new by letting the data come first, without a lot of editing or parsing. Here is a slice of the raw goods, a kind of behind-the-scenes look at the data we gathered from our survey of nearly 3,000 managers and executives from every major industry and all regions of the globe. (Also see “10 Insights: A First Look at The New Intelligent Enterprise Survey.”)

We chose these 10 charts to share because they captured our attention. Some are provocative, some are telling, and some raise questions we haven’t even tried to answer yet. They’re by no means comprehensive, and our final report will cover many more points accompanied by rigorous analysis. But we do think you’ll find these graphics worth a look if for no other reason than that they allow you to do some immediate benchmarking. How does your organization compare with others? What are your peers doing, and how might that influence decisions you’re considering right now?

The survey respondents answered two questions that allowed us to group them and their answers in some interesting ways. One question asked them to assess where their organization is along the journey to an ideal state: an organization that has been “transformed by better ways to collect, analyze and be prescriptively guided by information.” Those that were farthest along that path we deemed Sophisticates; those who were midway became Intermediates; while those that were just beginning to look at data and analytics we called Starters.

We also asked them to describe their organization’s competitive position. Those that rated themselves as substantially outperforming their industry peers we named Top Performers. Those that were underperforming we labeled Lower Performers. You’ll note both groups called out in the accompanying charts.
1. Innovation is the Top Business Challenge

More than 60% of all respondents chose innovation for competitive differentiation as their main business challenge over the next two years. In a recessionary business climate, doing more with the resources and talent you already have is always a favored strategy. When we parsed the data, we found that Starters (new users of analytics) were entrenched in “survival mode,” focused on cuttings costs and creating efficiencies as their main challenge. Intermediates (moderate users of analytics) were in “growth mode,” focused on growing revenues. Sophisticates (advanced users of analytics) were in an “expansion mode,” focused on growing revenues and expanding their customer base through acquisition or retention strategies, perhaps because their use of analytics had already helped them optimize their operations and general growth approaches.

Early returns are in from the first annual New Intelligent Enterprise Survey. Here are major highlights of what executives and managers said about how they are — or are not — capitalizing on information.

Camara support in HTML5 and JavaScript

At the moment, there are very good efforts to be able to access devices directly with HTML5, which would integrate native webcam support directly into the browser. However, there is still the fundamental problem on the Internet that most systems do not support HTML5. Even the current browsers do not provide the update functionality, which would cover the needs of today’s speed of development. This topic, however was already discussed in a previous article.

Resolve many-to-many relations a bit different with MySQL

In database modeling, a m:n relationship is usually resolved by an additional table. But what if this relation is used only for archiving and the number of links in the resulting table is not too high? In that context, I got the idea to store all referring ID’s as CSV string directly into a TEXT column of one of the referring tables. I came to this idea, because otherwise I would have to build complicated foreign keys and this way I also save one additional table. Certainly, this only makes sense if the data is not frequently accessed as foreign key. Nevertheless, I would like to tackle the problem, even if the implementation is very MySQL-oriented.

SQL-modes right to exist

At the beginning of a new project, one is faced with the question if MySQL’s strict mode should be used or if the default behavior is sufficient for most scenarios. This mode certainly makes only sense if you evaluate the error codes and acting accordingly in the application – thus, it would be a bad idea to apply SQL modes to a running system. Unfortunately, SQL modes are not really common and have thereby a few bugs. Also the fact, that the user can bypass the mode in the session raises the question whether it makes sense to use these settings at all. I decided to only set a selected list of options; just what really makes sense and improve the behavior of MySQL. Strangely that these modes are not set by default, what one might expect, as they are close to a natural approach of databases usage.

Use MySQL binlog to collect accesslogs

The easiest way to get user statistics from your own site is probably binding third-party tools like, e.g. Google Analytics into your code or parsing the logfiles with AWstats or webalizer. Evaluating your own logged data is the best way to look over the (imaginary) shoulder of users and bots. Moving static content on different servers remain the accesslog also manageable and free from unnecessary data.

My jQuery Playground

Probably the biggest problem of a high degree of specialization may be that learning outcomes can be long in coming if you do not even open up new areas of studies for yourself. So I was looking for a system that I’ve never used before. The second criterion was that I wanted to quickly achieve results to have something demonstratable at the end of the day. Thus, I have to announce two new jQuery plugins, which are really useful – at least, I hope you also see the benefits 🙂

Combine CSS and JavaScript with lighttpd

Optimized way of getting subqueries at once using JSON

Imagine we have a user table in MySQL and similarly, a products table. Each user can now busily buy items. But this is not what this article is all about. This article is more about, that users can also favor articles they like. From a database point of view, this represents a m:n relation, which is resolved by an additional table. We now want to display a list of all products and all users who favor a specific article. In real world scenarios, this can be a really big amount of data, but let’s bring an approximation later into play and focus on the main idea for the moment. In addition we want to know, if the person who is actually logged in into the system, already favors a certain product.

Design a developer friendly web

A few years ago, I’ve started creating a list of features, that web-browsers should be able to do, to build rich Internet applications without complicated tweaks and hacks. The time passed away and nowadays, many creative heads concern on web-development, thus some of my ideas landed in HTML5 or other web-standards, without my help. So, I want to show an extensive collection about techniques of browsers, which are already implemented, and which are still needed for developers to design the Internet of the future.

Is an angle between two other angles?

Disable ON UPDATE CURRENT_TIMESTAMP in MySQL

In a few scenarios, I prefer using the data-type TIMESTAMP of MySQL, with the flag ON UPDATE CURRENT_TIMESTAMP. This is much easier and even faster than using a trigger which sets a specified column to NOW() or CURRENT_DATE(). I love this feature, when it comes to set last modified flags of tables. Now, I encountered a problem with a tagging table by using the flag. Every tag in the table has besides the tag-name, also the aggregated number of relations and a timestamp of last update (or the insert). Everything is okay, until you want to update the aggregated column, when the numbers are wrong for any reason.

Optimizing integer multiplication

I’ve already mentioned the topic integer-multiplication optimization in the article about my mathematical failures. I was quite obsessed with the idea and while I looked over some results of this optimization method, I noticed a beautiful pattern in the binary representation. I wrote a small algorithm to get all possible numbers which can be optimized a bit as constant factor of a multiplication. The algorithm is implemented in JavaScript, so if you’re interested in the source code, feel free to read it.

Dynamic thumbnail generation on the static server

It’s quite natural to use features of the main programming language used in a project to generate user thumbnails or thumbnails of other images. Let’s assume, that we generate 3 sizes of every picture. With a rigid system, you would generate every size and store them temporarily on the webserver until it wasn’t uploaded to the static server. That means we have a lot of write operations on the webserver to generate the small pictures and finally writes to upload each of these pics to the static server – the CPU cycles intentionally left out.

The Anatomy Of A Tweet; More Than 140 Characters


Image representing Twitter as depicted in Crun...
Image via CrunchBase

Twitter, most affectionately known for its 140 character limit, has become one of the most powerful social media tool in spreading a message. However, what we are not aware of, are the things that go behind a tweet. To developers, they are aware that a tweet contains far more information than the 140 character limit itself.

Thanks to Raffi Krikorian, a developer on Twitter’s API/Platform team, we can now see what a tweet really looks like, in all its data-rich detail. Developers take note of this data infographic; as for the rest of us, we can only be in awe realizing that there are more than 600 tweets sent out per second.
