Being able to concentrate on a problem is a wonderful thing. The idea that you can have some peace and quiet and really get your head around a problem is, to me, a blessing.
So why do many organizations screw this up? Joel Splosky is the CEO of Stack Overflow. For those unaware of Stack Overflow, it is a very popular site for developers to go to get answers to questions. It is the site to go to. If they don’t have the answer than you have a very unique problem or you need to use different keywords when searching. Joel doen’t like the concept of the open office. His anecdotal evidence indicates that developers don’t like it either. Continue reading “Concentration Is Not Overrated”
When you call a service you invoke an API (Application Programming Interface). The idea of an API is old but has survived the introduction of thousands of computer languages and processes because it is a necessary piece of application development. The advent of cloud computing has raised the status of APIs to a new level. There are APIs to access services from numerous cloud providers. These APIs allow you to do almost anything you can imagine from creating virtual machines (Powershell on Azure), exploring the latest news feeds from a company (RSS) to seeing what your favourite celebrity is posting (Twitter, Tumbler, Instagram, etc.) Continue reading “APIs May Require A Cultural Change”
A few days ago I received an interesting email, it was from the New Mexico Medical Center welcoming me to the Patient Portal. I was a little confused as I don’t live in New Mexico, have never been to New Mexico and, to the best of my knowledge, have no know relatives in New Mexico. A little curious I opened up the first email and started reading:
Dear DANIEL JESSOP,
We are pleased to inform you that online access to your electronic health record is now available through New Mexico Medical`s Patient Portal. The Patient Portal is a secure website that allows you to communicate with your health care provider and to view parts of your electronic health record. This tool will help you better manage your care and enhance your partnership with your health care team.
OK, so obviously someone put in the wrong email address (mine) instead of theirs and I got sent the welcoming email. I was happy that they didn’t actually provide any confidential information in the email as that would have been … awkward. The part I liked was :
For security reasons, the activation code will be sent to you separately.
So the New Mexico Medical Center was going to send me an activation code that I would need to activate my account. Cool, so they will send it to the correct mailing address and I don’t have to worry about it. I pop out of this email and … oh, oh. Sitting in my inbox is the Patient Portal Activation Code. Well, this sucks. Daniel Jessop created a userID with the name of “djessop1”. (Wait, there is another djessop other than Daniel in New Mexico?) I now have the link to activate his account and the activation code necessary.
What do I do? I can now active Daniel Jessop’s account with his health care provider and pull out all of the information about him.
Well, I’m a sucker. I thought that I would be nice. The note says that if there are any problems with setting things up to give them a call. So I proceeded to do that. Multiple times, across multiple days. In fact, I checked time zones to make sure that I was calling at the correct time. No one answered the helpline. I didn’t even get a recorded message saying that they were busy. I didn’t get voice mail. I got diddly.
So there are some interesting lessons to be learned here:
If you are setting up an account for someone, make sure that they can actually access the email account that they enter. They may have made a mistake and you need to take that into account. Something like time limiting the activation to xx minutes, but you need to do something.
There is no use at all of sending a welcoming email and an email with an activation code. Either put them into one email or send the activation code via another method, but two emails to the same account? Completely amateur.
If you have a help number for people to call, you darn well better staff it or at least let the phone go to voicemail. No response is not adequate, particularly since you are dealing with someones electronic health record.
Clean up your website. (OK, I dissected the link a bit.) If I go to the root of the activation link I get the default IIS web page. I now know which operating system and version of IIS they are using. I know that it is an ASPX page hosted by a third party and that third party has not kept up with security patches. If you are going to host patient data you better harden your website.
In essence, if you are ever in New Mexico, avoid the Eastern New Mexico Medical Center as your data could end up in Canada.
You can’t be Agile if you don’t use the right test data
Developers often copy subsets of production data, sometimes anonymizing it but not always and rarely considering whether the test data contains sufficient diversity to exercise all important edge cases. And those are the more mature dev shops!
The quotes come from two different Forrester articles but are representative of dozens of articles about testing and quality assurance. But this is not just representative of Forrester, it is representative of the IT industry as a whole. Let’s dissect each piece and see what we come up with. Continue reading “Test Data”
So, cloud computing. Kind of a big topic with so many different things that can be discussed. But’s let’s focus on one very narrow thing: scaling up vs. scaling out.
There are two main ways of increasing the performance/capacity of an application and that is by scaling an application up (faster processors, bigger machines) or scaling it out (more machines). When you have an application on-premise, in your own data centre, you get your choice of how to scale an application. Continue reading “Scaling Out versus Scaling Up”

There are two radically different approaches to something like security: assume that you can prevent something from happening or assume that the worst is going to happen, how are you going to recover.
I can’t lay claim to the name, it comes from mathbabe.org. Her subtitle is “How Big Data Increases Inequality and Threatens Democracy”. You would think, based on that subtitle, that she doesn’t like Big Data. On the contrary, she likes it, but it needs to be used effectively. Continue reading “Weapons of Math Destruction”
I love learning new words, especially if they help to explain something in a way that I never thought of. For instance, let’s take the following word:
idempotent: the property of certain operations in mathematics and computer science, that can be applied multiple times without changing the result beyond the initial application
Or, at least, that is what Wikipedia says. But, what does it really mean? Suppose you had a function that updated someone’s birthdate and you called it with the value ‘1984-04-03’. Afterward, that person’s birthdate would be ‘1984-04-03’. It wouldn’t matter how many times you called the update function, the value would still be the same. Reading data is an idempotent operation as no matter how often you read it the values are the same. Continue reading “Batch Processing”
How many of you guys run projects or are involved in projects? How many of you run maintenance or are involved in maintenance? (Yeah, I read my own note from yesterday.)
So, that’s a lot of you. I bet that a good portion of you are Agile projects that use sprints. Did you know that an Agile project doesn’t necessarily contain sprints? Sprints are a Scrum concept that many Agile projects have adopted. But have they adopted it properly? How many of you realize that at the end of a sprint you need to have an application that can be deployed? Wow, the number of hands that dropped was amazing. Let’s get some definitions out of the way first: Continue reading “Agile Is Not Another Form Of Waterfall”
OK, here is the discussion about maintenance versus development. I mean there are hundreds of things that are different between maintenance and development right? I mean maintenance needs to keep track of source code and development … well, developments need to do so as well. OK, how about resourcing? I mean maintenance for a year has a defined start date and a defined end date and a certain amount of resourcing. Development teams? Well, they have a start date, an end date and a certain amount of resourcing. OK, but maintenance deals with small things, five or ten-day tasks and development deals with larger things and that’s different, right? RIght? Continue reading “Maintenance vs Development”
