- Lack of leadership in developer operations
- A lack of reporting of improvements in code reuse, coverage, test cases, and stability.
- Underutilization of frameworks and libraries used within the project.
- Lack of disposable runtime environments [for development and testing].
- Build times are unknown.
- Long and detailed documentation is required to build your product.
- Dead code is left in the code base to rot for years.
- Bugs are being reproduced as unit tests.
- Third Party dependencies are not being upgraded.
- Code is badly organized. Models are placed anywhere, packages aren’t organized, etc.

For the last decade, wikis have not changed very much. Even minor features such as AJAX support are still uncommon items. The following is a list of features I’d like to see added. A few of these items are available as plugins, however I am referring to having these features baked into the actual product.
Live Collaborative Editing
If you use Google Documents with others you will notice this: live collaborative editing. Usually the first time that someone notices this it either freaks him out, or just blows his mind. Multiple users can edit the same document at the same time, whilst receiving the changes in real-time. Having this support on a wiki would make the page lock / change conflict problem go away.
Importing Data Framework
It would be immensely helpful to have some sort of feature within a wiki to import data from other sources: images, RSS feeds, CSV feeds, etc. With a uniform way of bringing-in data, plugins could become a bit more generic and support the transformation. For example: let’s say that you have a build system, and it produces a build log file. Wouldn’t it be helpful for having that file be placed on the wiki [within a certain section] where it could be commented on? With a data framework, there could even be a plugin that could grep the output and only show the important sections.
Charts are important for simple visualizations of data. Why this requires selecting and learning how to use a new plugin is beyond me.
Wikis seem to be text based only. I have only found a small handful of plugins that support the editing of pictures. Even fewer use SVG. I’d like to see the ability to edit an SVG picture built into the wiki software.
Why wiki software continues to roll their own authentication system by default is beyond me. This item seems like a no brainer. Create an OpenID authentication mechanism that uses the top providers [Yahoo, Google, Facebook]. If need be, revert to a local authentication method if there is a lack of internet access – or if the wiki is being deployed exclusively internally.
APIs for Dealing with Content On The Wiki
Lastly but not the least important, create and promote a uniform wiki API. This would allow for other systems to automatically push content onto the wiki, or pull it. This would be great for a monitoring system to:
- create a new page on the wiki
- post configuration details and current state
- maybe even show statistics
Also with the API, the same monitoring system could grab a wiki page and check for changes in the configuration details. Granted, there are potential issues with the configuration details changing on a wiki, however at the moment this is more of an idea rather than a real world implementation.
Another example: WordPress could use wiki support to have multiple editors collaborate over a post within a wiki Page. WordPress could also, with an API, pull the wiki page to make it a blog post.
I have a bone to pick with the industry I associate with. The tech industry struggles to clearly define the expectations of whatever is desired. This is pretty much a universal issue with the industry. There are always hidden requirements. Job listings are no different.
The bone I have to pick is with the titles/job requirements. One of the worst offenders of this is for a Java Software Engineer. Based on the availability of frameworks, and meta-frameworks, asking for a Java engineer is quite ambiguous. This could ask for a graphics developer, API designer, web developer, Computer vision expert [CV in java is possible with native libraries, trust me!], core libraries developer, or even a micro-JVM developer. The amount of variability with the language makes a generic “Java developer” title frustrating.
As a potential candidate, it is incredibly frustrating to see the “Java Developer” title. Some titles ask for experience in Spring, Hibernate, Solr, Lucene, JAI, J2EE, etc. It’s incredibly frustrating to go into an interview, where the listing asked for all of these and then only be grilled on the minute [rarely used] inner workings of Spring RMI. Just the Spring framework alone asks for a lot. Of all of the potential avenues of spring that one could master are: Message queuing, Web services, Roo, Security, Integration, Web flow, MVC, BlazeDS, Batch, Social, and mobile. That’s not even accounting for the frameworks that you can substitute between the pathways for Spring. I’ve worked with a late Spring 2.x and early 3.0, I was not even aware of the new BlazeDS, Batch, social, or even mobile options for the framework. Things change quite quickly.
Besides ranting, what is the purpose of this article? I believe that the Java title should be a bit more specific. If you want a Java developer that knows a lot of frameworks, still label it as a Java developer position. However, don’t expect him or her to know all of the inner workings: that is just silly. If your business involves multimedia display, request a developer that knows the Java 2D and 3D graphics, and maybe the JAI libraries. There is a lot there for practically any task you want to throw at Java, given you know which library to use.
Scientific or mathematical tasks, ask for a Scientific Java Developer. What libraries should they know? Colt, EJML, JAMA, etc.
Writing a Java API? Ask for a Java API Designer. Expect for them to list their favorite APIs, what works, what doesn’t, and why.
Web applications? Ask for a Java Web Developer. Maybe they should have experience with a SOAP framework, MVC framework, Play, GWT, basic Web skills, and maybe even a non-SOAP based webservice library [REST, Hessian/Binary]. Please don’t use the enterprise title unless you need someone who knows EJB, and/or ESB frameworks.
Moreover as an employer, be more specific the first interview/inquiry on what the job is asking for. If an job application asks for the common ORM Hibernate, how much should one know about it before applying for the position? Should they be able to know how to wire up beans to their DB analog? Should they know how write their own dialect for a new data source? With JUnit, should the applicant be expected to transition your current development methodology to TDD? Should they know how to extend the JUnit framework?
At this point, you should be getting the picture. Different tasks demand different skills. Specify what you’re looking for. Find people that can learn new skills and that are interested in the same problems you are. People who have an active interest can learn what is needed to get up to speed. If you go to a butcher and ask for meat, you’re always going to get what you asked for, but not what you were craving.
Addendum: This can apply to an Erlang, C++, Python, and most other developers. The role of Java currently has such a great demand, and such an ambiguous title, making this article a little easier to communicate.
After watching the video “The Web Will Die When OOPs dies” and reading a few hip articles, on “how to improve your code,” gave me an idea. If someone is writing to give advice on improvements they should provide real world examples to why their suggestions/fixes to a language/framework are necessary.
Instead of articles of “Top 10 ways to improve your code;” I’d rather see an article about how something was improved. Take small segments from your own application or an open source project and write up a small report on how your suggestion[s] improved it. If you’re writing an article for developers, we’re interested in the proof and technical content. If your suggestions didn’t work out, we’re still interested in the story about the journey, or the technical observations that you found. Making vague suggestions and recommendations (without evidence) bore a technical audience. When you make vague suggestions to someone, you’re making an statement that you know more about their work or problem than they do. Your audience should be intelligent, if not then still write for an intelligent audience. Vague statements don’t address interesting problems, or new approaches.
So going back to the video I mentioned earlier. I like his tactless approach. He’s taken a good deal of experience from web development and he is presenting his argument. He doesn’t attempt to ask for others for opinion, nor does he attempt to tell his audience how to do their job. He just merely presents issues that he found, and his way of trying to solve those. The last thing that I loved about his talk is that he never once tried to push the latest hip language or framework. He mentioned a few frameworks, and then made a critism.
Part one of a continuing series.
There are two ways to learn something. The first way is to learn from another’s advice [the easy way], and then there is the hard way [through experience and making mistakes]. When starting out in a Computer Science degree, learning the material and concepts will require a lot of effort. [the hard way] It’s not a wrong way to go about it. The hard route helps to reinforce the material. However, not everything in your journey to become a software developer has to be difficult.
One of the most frustrating things for a student, when in a Computer Science program, is producing a deliverable to submit. Many students, outside of the introductory course, quickly find out that a few quick hacks won’t get the highest grade available. Many professors require documentation, specific file layouts, compliable code, funky submission instructions, build instructions, shout-outs in the comments (1), or even coding conventions. These extra/non-technical requirements add to more complexity and make assignments more difficult. However, they do have merit and “build” the student’s technical character. In academia, there are very few courses in the US that will teach the tools of the trade, this is something that the student is left to learn on his or her own.
So what does this have to do with answering the question: What should I [as a current Computer Science student] learn? Build systems. Learning how to consume a web service to Facebook or writing the next twitter client is great, however learning how to use a build system will make your professor’s, and your life much easier. A build system is an external tool [usually separated from an IDE] that defines the instructions on how to build an application. In addition, it makes your life easier when questioning if your attempt was worthy enough to submit. Did the build system pass and produce a deliverable? If you have all of the rules and unit tests configured to run, the answer is easy… Yes! Once you are confident that the assignment was completed to satisfaction, you can go party err study ‘social algorithms.’
So let’s imagine that you have the following requirements from a professor:
- Build a chat system [One client, and one server]
- Include unit tests for every method used
- Include Java Doc
- Email to: firstname.lastname@example.org
- FTP The resulting zip file to: ftp server.
- Create a readme at the base, and include your name and the word “Screaming Monkeys” within the readme file.
- Include instructions on how to build your software
- Use the following file format:
Building a working chat client and server solution may be difficult for someone that has just learned about sockets and lacks experience. The non-technical requirements could become overwhelming. However the assignment never required all of the non-technical instructions to be performed manually. I have NEVER heard of a professor that will take points off for using these tools. If anything, using a build tool will improve your grade. It allows for you to plan for these requirements ahead of time, and let software handle the rest for you.
“But hey! That looks like a lot of work to do a few simple steps!” You’re right; all of those steps can be performed manually and probably quicker. However, if you screw up part of your final deliverable [code doesn’t compile, you forgot a unit test, or the code conventions weren’t followed], you’ll have to perform all of those menial tasks all over again. With all of those tasks, Ant can perform those automatically by just typing in “ant.” You can configure ant to build the software, run all of the unit tests [and stop the build if one fails], configure the output of the java doc, run utilities [to confirm that your name is there, and the “special word”], perform all of the file manipulation and deliverable locations, and even submit the result [ftp, email, source control]. If there is an ant task for the action, you can use ant to do it. Another benefit is that it can even run the source code through a “coding convention” checker. Have a professor that requires you to use the K&R coding convention? No problem, just add a check or reformator in the build environment. Problem solved.
In summary, assignments in computer science are difficult with the shear amount of demands. Reduce the potential for mistakes by automating the tedious tasks. Learn a build system early in your education. It will help ensure consistency in your code, get rid of annoying non-technical requirements, and make your work a lot simpler.
Need another reason? Do it for getting a job after you get out of school. There are very few students that have even used a build system prior to entering the work world. Most students entering the work world have to learn at least one build system as soon as they start their first job. The software industry thrives on build systems. If they aren’t working, the developers are unable to progress. Hey, worst case scenario: Let’s assume that you’re not a very good CS student, and you barely pass with your CS degree. If you know a build system extremely well, you can still proceed with a career of being a “Build Systems engineer.” Those guys can still make quite a lot of money. [Indeed claims that a build engineer starts at $50k and has a sizable amount of jobs that will earn $130k+ a year]
Some of the build systems that are currently in use:
- Ant [Good for nearly every language out there]
- MSBuild [Good for the MS supported language (VC++, VB?, anything .NET)]
- Make [Good for C++, and bash]
- Apache Ivy
(1) In my prior work as a teaching assistant I am guilty for supporting the shout-outs rule. The requirement was for the student to include his or her name in the top of the file. This was mentioned on the grading rubric (included in the assignment writeup/specs). It’s a simple request to complete, and it makes the grader/professor’s life a lot easier. It’s akin to asking elementary school children to write their name on top of the assignment. A lot of new students don’t add their name to their code.
This is a list of potential tips to help a fellow Software Engineer recover passion in his or her work:
- Learn A New Language: Stuck with working solely in Java and C++ languages? Learn Erlang, or Lisp. Try out Scheme, Perl, Bash, Haskell, or D.
- Learn a New Framework: Some of the frameworks to learn: xUnit, Testing frameworks [other than JUnit], Spring.net, Apache Tapestry, XMPP, Esper (Complex Event Processing), OpenGL, JasperReports, OpenCV, Win32, OSGi, or even Hessian binary web services.
- Revive old projects by refactoring the code to use a new framework. Review code in open source projects.
- Attempt to become an expert in an open source project. You might become an authority on the subject, and write a book.
- Meet new developers. To do this, branch outside of your company and go to user groups related to the language. JUG for Java groups, LUG for Linux user groups, NUG for .NET user groups etc.
- Read and listen to lectures on InfoQ.
- Take a “Thirty Day Challenge” by coming up with a complex application and writing it in a completely unfamiliar framework or language. Something that would be rather unique, write a web application completely in Prolog or Erlang. I haven’t heard of anyone that has done that yet, but it would be rather interesting.
- Annoyed with an application, language or framework? Fix it. If it’s open source, then write a fix for it and publically submit a patch. If it’s due to a closed source application, then rewrite the main interface [if it connects to a backend service], or rewrite the application completely.
- Have a business idea? The book “The Lean Startup” suggests that startup-interested developers should create a stripped down demo, to gauge market interest.
- Add new “favorite tags” to your StackOverflow account. Look for questions that contain lots of votes. Look for questions that have not been answered in a long time, research a solution and answer the question.
- Find ways to make your current job/task easier. If you are spending a lot of time writing the same type of unit tests over and over again, find a way to automate this, or write your own domain specific framework. Even better, write a Domain Specific Language for the current development project.
- Use coverage tools to find new places to test code that is currently untested.
- Read research papers. This is typically a very dull task, but there are some quality papers available. It takes some effort to find those papers, but the ones that are well written are worth ones effort.
- Hack: [I'm not responsible for unethical/illegal actions, I would suggest doing these things only for personal interest] Setup a VM to learn how to exploit system services, learn how to perform a privilege escalation, learn how to write a buffer overflow and run shell code, learn how an intrusion detection system works and attempt to exploit them, and attempt to crack legally obtained software. [I advise that the reader do these things ethically (don't share a software crack). The reader is responsible for his or her own actions. ]
- “Hack Hardware”- Write an application that interfaces with an Ardinio device. Root an Android or Apple phone. You could also go the route that Linus Torvalds went, take data from existing devices and write an application that interprets the data. His project is SubSurface, its designed to take the data from a dive-computer, and to transform it into something the user can add notes to, and visually interpret the data. Write software for an embedded processor (FPGA, Basic/Java stamp).
- Learn how to make your own operating system. Take a Gentoo distribution, and reconfigure everything. Try out a real time Linux distribution.
- Look for project suggestions on Stackoverflow. There are quite a few questions from students asking about project ideas. One popular suggestion is to write a plugin for a popular game. From my understanding, one can write a plugin for Civilization 4 by using Python.
- Find ways to make your job more fun, or easier. Identify tasks that are uninteresting or tedious and find a way to automate them. Learn how to configure and/or extend a build tool. Learn Ant, Maven, or Gradle.
- Take a vacation: Over-working one’s self is not an achievement, no one is impressed.
Lastly, (This really isn’t considered to be a tip) to help connect with others who have a similar interest to what you’re doing, write about your attempts, successes, or failures in a blog. Even if you decide that your current job is not fulfilling, then these are things that you can mention on your resume or future employers can see on your blog.
You’re a developer, as a developer you have the unique ability to create things. There is very little holding you back from developing something you want.
Have I missed some important tips? Have these tips help you? Are there any languages or frameworks that one should study? If so, leave them in the comments box.
Forewarning: I’m not an expert on this subject, however I do play one on television.
Software engineering is mostly a solitary, and technical occupation. Most of the non-programming language communication made by a developer is communicated to another person with domain, contextual, and similar technical knowledge. Very rarely, information is communicated to someone outside of the domain, or contextual atmosphere, let alone technical knowledge. This guide is more of a collection tips and reasons to document that I’ve discovered over the years.
- Acknowledge your audience. For frameworks, nothing is more frustrating to the reader when a quickstart guide is written for existing developers of that framework. Those developers do not want a quickstart guide, they want the Java/Net-doc. I’m looking at you Spring. If your audience is technical and new to your framework, please identify concepts that are exercised within the framework. Preferably, as an appendix and referenced to at the introduction of the book/document.
- Proof-read the document, even better: Have someone, even better people, from the targeted audience proof read the document for accuracy and readability. It is unbelievably surprising to discover how difficult it is to write documents that deal with troubleshooting, installation, configuration, or documentation of “common tasks.” From my experience, just the modification of an existing code base to add a new report took 4-5 pages of bullet point instructions. Once a documentation guide is published errors/incorrect documentation is embarrassing, are difficult to correct, and can be very costly.
- Screenshots: Screenshots make describing tasks involving a GUI clearer.
- Pictures [more than screenshots]: Reading words are useful, however a simple diagram is often useful for explaining complex architectures, or tasks. It also includes people who are visual learners.
- Versioning the document: This helps the user identify the document’s “up-to-date-ness.” I really hate advising this, as that some documents begin to include the change list. [Who really cares about this? All I want to know, as a reader, is if I have the most current version]
- If you are documenting source code and haven’t written by the time that you get to the unit test. Write the documentation while the tests are being written. If the documentation has already been written, write the unit tests based on that, even if you have access to the source code. From my experience this can piss off the original developer. However, as a tester, you should depend on the resources given to you, not what the actual structure is. From my experience, this level of pedantry can piss off the original developer, but in the long run it may prevent major errors in future reuse of the code. Make the unit test break if the documentation isn’t followed!!
- Provide documentation! Your developers/designers/user’s are very intelligent, however being intelligent does not make one a mind reader. Don’t expect another person to understand your [or your team's] motivation, history, design decisions, or politics surrounding the project.
- Allow for feedback. If there is mistake in the documentation, provide the user to contact the author of the documentation for confirmation of a mistake. If you don’t do this, expect for people to be pissed off about your API, idea, project, source code, or product.
- Document bugs or deprecation: If something doesn’t work or is going to be removed. Warn the developer. It’s better to know beforehand.
- Support: Support is more than a scripted technical support call. If you have better documentation low level support calls can be eliminated or substantially lessened. Additionally, supporting the documentation/product can give insight to the functionality used in the product and/or bugs that were previously not found.
- Job Security: It may sound contradicting (Most people I’ve talked to claim that obfuscation keeps a person employed for a while, at the expense of others), however it’s hard to claim that a person isn’t doing the job they were tasked with, or deny a promotion if their procedures are sufficiently documented.
- Documentation can help you identify architectural and interaction [GUI, and API] issues. This is more of a case of an problem, previously unrealized, coming into the consciousness. You’ve identified the issue, now you can talk about it and come up with a solution.
- For APIs: Provide examples for every method. Write a paragraph on: why someone should use that method, why one shouldn’t use it, the performance and memory costs, and the state change to the operation of the software or environment.
Have tips for technical writing, documentation? Leave them in the comments! [See I even provided feedback for this post ]
Technology, since the introduction of a computer that doesn’t take an entire room, has always been suggested for educational purposes. Technology is sold as an existing off the shelf solution for teaching the youth of the country that it happens to be in. Policymakers and lobbyists tend to sell the idea of technology as an easy solution that just takes money to solve a massive problem.
When an education organization purchases a technology solution many things happens. Typically, given a healthy market, products are evaluated, money is appropriated, and the solution providers bid [through their price, and service offerings]. The goal in this market is to provide business for the producer through a bulk sale, and reduces the price for the consumer [the people who run the educational organization]. This is the only place where the ultimate beneficiary, the students, is represented is by the purchaser of the products. However, since price is a consideration in the sale, the people who ultimately use and learn from the product have to compete with price.
Approximately fifteen years ago, the utopian goal of “high class education” was to have popular educational software or to have internet access in the classroom. By putting this in the classroom it was assumed that students would immediately consume it and use it to fulfill academic interests. Well intentioned as this might be, it wasn’t the case. Few students used the internet for research, and for those who did typically did, performed poor research. The research came from poor resources, and nothing was taught about how to identify a creditable source. However, can you blame the ten year old, teaching him about creditable sources isn’t extremely easy to explain when they’re struggling on algebra. Most students in schools used the internet to fulfill their immediate, typically non-education related, interests.
I would argue that most students below the age of mandatory education are unable to determine what subjects are the best investments of their time. Mandatory education provides a basic understanding of our world and the options available. It provides an understanding for the person that options exist outside of their small town or city, and that society is no longer a basic rudimentary system of barters and trades or tradition based.
Recently there has been a lot of hype over the use of embedded systems. This started with the introduction of “learning toys.” Some of these include LeapFrog, and VTech related products. Typically the premise of a learning toy is taking simple concepts, dressing them up in cute and popular characters and making an electronic version, which can be easily purchased at the local toy store. These are an easy way for a child to reinforce what is taught from another source, however, they are not a great teacher.
One of the more recent fads in technology purchases in education is the use of iPods, iPhones, and iPads. Ironically, these are all produced by the same company, which reduces competition in the market. These purchases are typically favorited by those who have a financial interest or for those who deem it hip. These devices are not built for educational use. These devices are all built to be generic multi-use devices for communication, or entertainment. Many argue that these devices can be used educational purposes; however they were not designed to entertain the needs that an educational experience requires.
For example, if an iPad is used for an educational purpose, what stops the user from switching to OMGmyFavoriateCeleb.com or texting their bff Jill when the material becomes dry and uninteresting? If anything, an iPad, in this manner, cuts down on educational value. The cost of the switch in context [going from information to a pleasure seeking mode] eliminates analysis on the material that was uninteresting. Without the device, the user may wonder why he or she did not like the subject or why it may be dull.
Additionally, the issue with selling devices that were mentioned is ignoring the actual value they may have. The value of an iInsertNameHere is completely reliant on the applications that are installed and the use of them. The users of the technology will ultimate install what they want on it. Why install the “utimate visual guide on history” when you can install the latest fart application for only $0.99 (now reduced from $50). The only few applications where I can see a tablet that would be useful for education is for reading material (books) or music (a Finale like application). However, typically the cost of the books, in the format for the tablet, and the device itself would never be less than the cost of the books themselves. Given that the only situation where the statement would be false is for rare books. Given a situation where everyone purposed books as ebooks, that possibility may not be far off.
Now for the content that is less doom and gloom. Technology can enable people to learn. There have been success stories. Two of the best success stories are electronic publishing of scholarly journals, and the second one being the OLPC project. Electronic publishing of scholarly journals, attempts to help the academics field to reduce the publishing of multiple research attempts of the same findings, create new fields of study, and providing access to academic materials to more people than ever before. Electronic journals are typically subscribed to by universities and access is provided to students. Without electronic access, this would become quite expensive at universities with large amounts of students (with a high demand for articles).
The second success story is an odd one. The project is the One Laptop Per Child project. This project’s goal is to put MORE computers in the hands of more children. However the difference in the people who are getting the machines and the ones I was ranting about before, is that these consumers are children in developing nations. The project is not putting laptops are specifically designed for situations where the internet may not be widely available, or electricity may be a concern. Additionally these are designed for locations where educational materials may be rare or outdated. The main characteristic that makes this project successful is that these laptops are not built to be general purpose entertainment devices. These devices are created to limit the applications that the people can use.
When I was the target for these educational devices, also the time of the dinosaurs, there were a few educational games that came to mind. These games were “Mathblasters”, “Where in the world is Carmen Sandiago,” and “Oregon Trail.” These were fun games that weren’t designed to replace the educational experience.
Data visualization is a very useful tool for summarizing, and sometimes interacting with, complex datasets. It shifts a dataset from being a detail oriented process into a more comfortable visual process. Throughout evolution humans have had a great use for visual information. Being able to see the world and recognize its patterns has enabled us to spot the approaching danger, and choose healthier mates. It’s essential for the preservation and production of life. Granted, comparing the difference between data visualization and textual data is not the difference between life and death.
Despite the benefits data visualization is a methodology that presents itself as a panacea. It is presented as a technique that is “better than the alternative.” The issue with visualization is that it is rarely ever shown in context of the application that is requesting its services. It is the person that shows up to a Christmas party in their Halloween costume. The treatment of a visualization component typically attempts to dominate other modes of understanding on the screen. For example, when a visualization is displayed on a web page in the main content area it typically takes the eye away from any other descriptions within the content area or navigation options of the page. Descriptions of the visualization of the context of the visualization are more important than the visualization itself. The descriptions of the visualizations instruct the reader on what the visualization is summarizing and how to read the graph.
Since most visualizations are not contextually relevant the visualization tends to stand out from its surroundings. The goal of any visualization, unless it itself is the application, is to complement surrounding data give a visual overview. If the visualization is taking the eye away from the surrounding content the visualization moves from information to only data. Additionally, due to the lack of context, the user may become confuse or may underestimate the data behind it. This problem is amplified when the user is seeing the visualization for the first time. By creating more obstacles with the visualization the overall meaning becomes lost or ineffectively communicated. Additionally, differences in cultures may add another layer of complication in effectively communicating the data through visualization.
For the academic studying visualization, the issue of context of the application surrounding the visualization is not a main focus. The context disregarded as “window dressing.” After all, the academic has already had training on what the visualization is, what types of data that it’s good for, and possibly how to interpret the graph. However, they are not taught how to interpret the data from the graph. To effectively interpret the data from the graph, one has to have context.
News papers typically do not have the issues that I have outlined above. They do not have these issues because the focus of the article is not the visualization. Additionally, if a new article has a visualization, the visualization is non-interactive and takes up a very small percentage of the article it accompanies.
Some thoughts on how to improve existing visualization:
- Involve Human Computer Interface researcher/specialist to fix issues with interactivity
- Involve editors to fit the visualization within the context of the page and audience.
- Get graphic designers involved in the design of the visualization, and to have it fit the application.
- Maintain Constancy throughout the application/website
- Make the visualization very simple to use
- If the visualization is not common (most aren’t, and it is typically assumed they are)
- Give the user a preview of the visualization before they use it. This gives the user time to process the visualization as “I’m looking at something new here, time to switch to right brain.”
- If the visualization will not fit in the context of the application, then allow the user to open it in a new window.
