This year, privacy and surveillance issues have been all over the news. The most important, in my opinion, deal with the tension among:
- Personal privacy.
- General law enforcement.
More precisely, I’d say that those are the most important in Western democracies. The biggest deal worldwide may be China’s movement towards an ever-more-Orwellian surveillance state.
The main examples on my mind — each covered in a companion post — are:
- The Apple/FBI conflict(s) about locked iPhones.
- The NSA’s propensity to share data with civilian law enforcement.
Legislators’ thinking about these issues, at least in the US, seems to be confused but relatively nonpartisan. Support for these assertions includes:
- The recent unanimous passage in the US House of Representatives of a law restricting police access to email.
- An absurd anti-encryption bill proposed in the US Senate.
- The infrequent mention of privacy/surveillance issues in the current election campaign.
I do think we are in for a spate of law- and rule-making, especially in the US. Bounds on the possible outcomes likely include:
- Governments will retrain broad powers for anti-terrorism If there was any remaining doubt, the ISIS/ISIL/Daesh-inspired threats guarantees that surveillance will be intense.
- Little will happen in the US to clip the wings of internet personalization/recommendation. To a lesser extent, that’s probably true in other developed countries as well.
- Non-English-speaking countries will maintain data sovereignty safeguards, both out of genuine fear of (especially) US snooping and as a pretext to support their local internet/cloud service providers.
As always, I think that the eventual success or failure of surveillance regulation will depend greatly on the extent to which it accounts for chilling effects. The gravity of surveillance’s longer-term dangers is hard to overstate, yet they still seem broadly overlooked. So please allow me to reiterate what I wrote in 2013 — surveillance + analytics can lead to very chilling effects.
When government — or an organization such as your employer, your insurer, etc. — watches you closely, it can be dangerous to deviate from the norm. Even the slightest non-conformity could have serious consequences.
And that would be a horrific outcome.
… direct controls on surveillance … are very weak; government has access to all kinds of information. … And they’re going to stay weak. … Consequently, the indirect controls on surveillance need to be very strong, for they are what stands between us and a grim authoritarian future. In particular:
- Governmental use of private information needs to be carefully circumscribed, including in most aspects of law enforcement.
- Business discrimination based on private information needs in most cases to be proscribed as well.
The politics of all this is hard to predict. But I’ll note that in the US:
- There’s an emerging consensus that the criminal justice system is seriously flawed, on the side of harshness. However …
- … criminal justice reform is typically very slow.
- The libertarian movement (Ron Paul, Rand Paul, aspects of the Tea Party folks, etc.) seems to have lost steam.
- The courts cannot be relied upon to be consistent. Questions about Supreme Court appointments even aside, Fourth Amendment jurisprudence in the US has long been confusing and confused.
- Few legislators understand technology.
Realistically, then, the main plausible path to a good outcome is that the technology industry successfully pushes for one. That’s why I keep writing about this subject in what is otherwise a pretty pure technology blog.
Bottom line: The technology industry needs to drive privacy/ surveillance public policy in directions that protect individual liberties. If it doesn’t, we’re all screwed.
My blogs are having a bad time with comment spam. While Akismet and other safeguards are intercepting almost all of the ~5000 attempted spam comments per day, the small fraction that get through are still a large absolute number to deal with.
There’s some danger I’ll need to restrict comments here to combat it. (At the moment they’ve been turned off almost entirely on Text Technologies, which may be awkward if I want to put a post up there rather than here.) If I do, I’ll say so in a separate post. I apologize in advance for any inconvenience.
Taxonomy can be a nebulous term. It has existed for years, having probably its most common roots in the sciences, but has blossomed to apply its practices to a plethora of other fields. The wide application of taxonomy shows how useful and effective it is, yet its meaning can be unclear due to its diversity. We identify with taxonomy in library sciences with the Dewey Decimal System and we identify with taxonomy in the scientific use when we talk about animals (Kingdom: Animalia; Phylum: Chordata; Class: Amphibia; Clade: Salientia; Order: Anura (frog)). These are familiar uses to us. We learned of them early on in school. We’ve seen them around for years—even if we didn’t identify them as taxonomies. But what is taxonomy when we talk about subjects, like documents and data, that aren’t so tangible? As a Business Solutions Architect at Fishbowl Solutions, I encounter this question quite a bit when working on Oracle WebCenter Content document management projects with customers.
The historical Greek term taxonomy means “arrangement law.” Taxonomy is the practice in which things, in this case documents, are arranged and classified to provide order for users. When it comes to documents, we give this order by identifying field names, field values, and business rules and requirements for tagging documents with these fields. These fields then describe the document so that we can order the document, know more about it, and do more with it.
- Document Type: Policy
- Document Status: Active
- Document Owner: Administrator
- Lifecycle: Approved
- Folder: HR
- Sub-Folder: Employee Policies
- And so on…
Defining taxonomy for documents provides a host of business and user benefits for document management, such as:
- A classification and context for documents. It tells users how a document is classified and where it “fits in” with other documents. It gives the document a name and a place. When a document is named and placed, it enables easier searching and browsing for users to find documents, as well as an understanding of the relationship of one document to another. Users know where it will be and how to get it.
- A simplified experience. When we have order, we reduce clutter and chaos. No more abandoned or lost documents. Everything has a place. This simplifies and improves the user experience and can reduce frustration as well. Another bonus: document management and cleanup is a simple effort. Documents out of order are easy to identify and can be put in place. Documents that are ordered can be easily retrieved, for instance for an archiving process, and managed.
- An arrangement that makes sense for the business. Using taxonomy in a document management system like Oracle’s WebCenter Content allows a company to define its own arrangement for storing and managing documents that resonates with users. Implementing a taxonomy that is familiar to users will make the document management system exponentially more usable and easier to adopt. No more guessing or interpreting arrangement or terminology—users know what to expect, terms are common, they are in their element!
- A scalable framework. Utilizing a defined and maintained taxonomy will allow users to adopt the common taxonomy as they use the document management system, but will also allow for business growth as new scope (documents, processes, capabilities, etc.) is added. Adding in a new department with new documents? Got it. Your scalable taxonomy can be reused or built upon. Using a comprehensive taxonomy that is scalable allows for an enterprise approach to document management where customizations and one-offs are minimized, allowing for a common experience for users across the business.
- A fully-enabled document management system. Lastly, defining a taxonomy will allow for full utilization of your OracleWebCenter Content, or other, document management system. Defining a taxonomy and integrating it with your document management system will enable building out:
- logical folder structures,
- effective browse and search capabilities,
- detailed profiles and filters,
- advanced security,
- sophisticated user interfaces and more.
Clearly, a taxonomy is the solution to providing necessary order and classification to documents. It creates a common arrangement and vocabulary to empower your users, and your document management system, to work the best for you. Now hop to it!

This post comes from Fishbowl’s president, Tim Gruidl. One of Tim’s biggest passions is technology innovation, and not only does he encourage others to innovate, he participates and helps drive this where he can. Tim likes to say “we innovate to help customers dominate”. Tim summarizes Fishbowl’s Hackathon event, held last Friday and Saturday at Fishbowl Solutions, in the post below.
What a great event to learn, build the team, interact with others and compete. We also created some innovative solutions that I’m sure at some point will be options to help our customers innovate and extend their WebCenter investments. This year, we had 3 teams that designed and coded the following solutions:
- InSight Image Processing – Greg Bollom and Kim Negaard
They leveraged the Google Vision API to enable the submission of images to Oracle WebCenter and then leveraged Google Vision to pull metadata back and populate fields within the system. They also added the ability to pull in GPS coordinates from photos (taken from cameras, etc.) and have that metadata and EXIF data populate WebCenter Content.
- Slack Integation with WebCenter Portal and Content – Andy Weaver, Dan Haugen, Jason Lamon and Jayme Smith
Team collaboration is a key driver for many of our portals, and Slack is one of the most popular collaboration tools. In fact, it is currently valued at $3.6 billion, and there seems to be a rapidly growing market for what they do. The team did some crazy innovation and integration to link Slack to both WebCenter Portal and WebCenter Content. I think the technical learning and sophistication of what they did was probably the most involved and required the most pre-work and effort at the event, and it was so cool to see it actually working.
- Oracle WebCenter Email Notes – John Sim (Oracle ACE) Lauren Beatty and me
Valuable corporate content is stored in email, and more value can be obtained from those emails if the content can be tagged and context added in a content management system – Oracle WebCenter. John and Lauren did an awesome job of taking a forwarded email, checking it into WebCenter Content to a workspace, and using related content to build relationships. You can then view the relationships in a graphical way for context. They also created a mobile app to allow you to tag the content on the go and release it for the value of the org.
Participants voted on the competing solutions, and it ended up being a tie between the Google Insight team and the Email Notes team, but all the solutions truly showed some innovation, sophistication, and completeness of vision. A key aspect of the event for me was how it supported all of Fishbowl’s company values:
Customer First – the solutions we build were based on real-life scenarios our customers have discussed, so this will help us be a better partner for them.
Teamwork – the groups not only worked within their teams, but there was cross team collaboration – Andy Weaver helped John Sim solve an issue he was having, for example.
Intellectual Agility – this goes without saying.
Ambition – people worked late and on the weekend – to learn more, work with the team and have fun.
Continuous Learning – we learned a lot about Slack, cloud, email, etc.
Overall, the annual Hackathon is a unique event that differentiates Fishbowl on so many fronts. From the team building, to the innovation keeping us ahead of the technology curve, to all the learnings – Hackathons truly are a great example of what Fishbowl is all about.
Thanks to all that participated, and remember, let’s continue to innovate so our customers can dominate.
Hackathon weekend at Fishbowl Solutions – Google Vision, Slack, and Email Integrations with Oracle WebCenter
It’s hackathon weekend at Fishbowl Solutions. Fishbowl’s consulting and development teams – the hackers – along with members of the sales and marketing teams join forces to collaborate on and develop new software applications. While the overall goal of the hackathon may be to produce usable software, the event also is a great learning opportunity for participants and results in a lot of fun.
This is Fishbowl’s 4th annual hackathon and previous events have produced “beta” software that eventually evolved into shippable software components that benefited customers. Here are recaps on the 2012 and 2014 events.
This year there were over 16 different ideas, and out of those 3 teams were formed to develop the following:
- Oracle WebCenter Portal and Slack integration – Slack is a popular collaboration tool for the enterprise that enables members to communicate across channels (specific topics), send direct messages, and drag and drop files for sharing. Integrating Slack with WebCenter Portal brings its popular features and ease of use directly in context of a user’s portal session, ensuring that collaboration is easy and reducing the amount of switching between applications to communicate with others – leaving the portal to send an email, for example.
- Oracle WebCenter Content and Google Vision integration – This integration would enable the tagging of images upon check-in. The Google Vision API enables applications to understand the content of images by encapsulating machine learning models in an easy to use REST API. Using this technology, images are auto-classified into thousands of categories (e.g., “sailboat”, “lion”, “Eiffel Tower”). For example, you might check in a picture of a knit hat and it would be tagged with xKeywords of “hat”, “knit hat”, and “fashion accessories” without any human tagging. To further automate image discovery, the GSA can be used to map related terms so that searches for “beanie”, “stocking cap”, or “winter hat”, could also return the image. This tagging automation would have great implications for Oracle WebCenter customers that are using it for Digital Asset Management.
- Oracle WebCenter Content Email Check in - This integration would enable emails with attachments to be checked in to WebCenter Content automatically. Instead of the user having to check in the email itself, and then relating each attachment to the associated email, which results in additional check in steps, the emails and attachments would be parsed out and sent to a user workspaces in WebCenter. From there, users can tag and validate that the email should be checked in with the appropriate attachments – either from their desktops or mobile device.
The hacking commenced at 3 PM today and will continue until 4 PM on Saturday, April 16th. Each team will then present their developed integration/component, and the other Fishbowl team members will vote on their favorite finished product. Check back on this blog next week to see who won.
I’m thrilled to be presenting at Collaborate 2016 with my colleague John Sim, on the recently open-sourced Oracle JET! We front-end developers had been seeking a better UI/UX solution from Oracle for quite some time, and they have delivered in a big way.
Part of the beauty of JET, is in its modularity. It allows developers to use as much or as little as they need for a particular project. In addition, different libraries can be incorporated. As JS libraries evolve, and new frameworks are developed, the idea is that they can be incorporated, as well. Oracle JET’s flexibility ensures that it can change with the JS development world.
Fishbowl Solutions at Collaborate 2016: Demos and Discussions on Oracle JET, ADF, Documents Cloud Service, Controlled Document Management and Portals
Fishbowl Solutions is looking forward to Collaborate 2016. We have another full list of activities planned, and we are always excited to meet with customers and discuss their initiatives around enterprise content management and portals, the cloud, as well as front-end user design and experience. With the release of Oracle WebCenter 12c back in October, customers are also eager to understand more of what the new version has to offer. Fortunately for WebCenter customers attending Collaborate, Fishbowl Solutions will be covering all these topics across the 5 presentations we will be giving, as well as one-on-discussions in our booth – #1028.
We are also privileged to be joined by two WebCenter customers who will give presentations on their WebCenter use cases. The first customer, ICON plc (www.iconplc.com/) based in Dublin, Ireland, will discuss the process of improving the front-end experience of the WebCenter-based portal they use to manage the clinical trials process.
The second customer is Rosendin Electric (www.rosendin.com) based in San Jose, CA, and they will share how they implemented Fishbowl’s ControlCenter solution to automate the contract management process within WebCenter.
The best part and biggest benefit of attending Collaborate is hearing stories from actual customers, like ICON and Rosendin. Collaborate is truly a user group conference, and hearing case studies on WebCenter deployments, enhancements, integrations, etc., are invaluable for other customers looking to do the same or similar. Less marketing speak and sales pitches, and more learning. As you plan your schedule for Collaborate, look for Session Types denoted as Case Studies.
Here is a preview of what Fishbowl currently has planned for Collaborate 2016.

As an Oracle WebCenter consultant at Fishbowl Solutions, I have a number of tools that I use that keep me happy and productive. Whether or not you are a software developer, these tools can do the same for you and your business.
Unless you’ve been hibernating for the last year or so, you’ve probably heard of Slack. Haven’t adopted it for your business yet? Here’s why you should.
Slack facilitates contextual, transparent and efficient communication for teams. Slack helps organize your communications into “channels.” Working on a project with Fishbowl Solutions on a WebCenter project? Create a Slack channel and centralize your communications. Quickly share files with the entire team, and “Slackers” can give instant feedback. On the go? Slack goes with you via mobile, of course. Slack provides direct messaging and private channels, too.
Even better, Slack lets you integrate dozens of apps, so that you can centralize all of the services you and your team use. Send calendar reminders and events, search for documents, even start a Skype call. Slack is team communication for the 21st century (with custom emojis!).
Twitter and Evernote
Trello is the application for list-making over-achievers (like me). I organize my to-dos into different “boards”, depending on the project. I have a different board for each project I’m working on at Fishbowl. As I think of something I need to do, I can quickly add it to the appropriate to-do column. When I’m busy with a task, I put it in the “doing” column, and then slide it on over to “done” when finished. I can keep up with my task flow, it’s motivating, visually appealing, and goes with me where I go. Trello also allows me to share tables with others for easy collaboration. Oh, and did I mention I can integrate Trello with Slack (insert custom Slack emoji here)?
Toggl is a fantastic little desktop timer tool my colleague Nate Yates introduced to me. We consultants at Fishbowl Solutions need to keep very accurate timing of the hours we spend on different projects. Toggl allows me to input my different projects, and then just click the appropriate button when I start working on it. It keeps track of my time for the week on each project. It makes keeping track of my time simple, so that I can focus most of my time on creating responsive single-page applications for Fishbowl Solutions customers.
The post A Few of My Favorite Things for Ultimate Productivity with Oracle WebCenter appeared first on Fishbowl Solutions' C4 Blog.
Whenever somebody asks for my help on application technology strategy, I start by trying to ascertain three things. The absolute first is actually a prerequisite to almost any kind of useful conversation, which is to ascertain in general terms what the hell it is that we are talking about.
My second goal is to ascertain technology constraints. Three common types are:
- Compatible with legacy systems and/or enterprise standards.
- Cheap, free and/or open source.
- Proven, vetted by sufficiently many references, and/or generally having an “enterprise-y” reputation.
That’s often a short and straightforward discussion, except in those awkward situations when all three of my bullet points above are applicable at once.
The third item is usually more interesting. I try to figure out what is to be accomplished. That’s usually not a simple matter, because the initial list of goals and requirements is almost never accurate. It’s actually more common that I have to tell somebody to be more ambitious than that I need to rein them in.
Commonly overlooked needs include:
- If you want to sell something and have happy users, you need a good UI.
- You will also soon need tools and a UI for administration.
- Customers demand low-latency/fresh data. Your explanation of why they don’t really need it doesn’t contradict the fact that they want it.
- Providing data access and saying “You can hook up any BI tool you want and build charts” is not generally regarded as offering a good UI.
- When “adding analytics” to something previously focused on short-request processing, it is common to underestimate the variety of things users will soon want to do. (One common reason for this under-estimate is that after years of being told it can’t be done, they’ve learned not to ask.)
And if you take one thing away from this post, then take this:
- If you “know” exactly which features are or aren’t helpful to users, …
- .. and if you supply only what you “know” they should use, …
- … then you will discover that what you “knew” wasn’t really accurate.
I guarantee it.
So far what I’ve said can be summarized as “Figure out what you’re trying to do, and what constraints there are on your choices for doing it.” The natural next step is to list the better-thought-of choices that meet your constraints, and — voila! — you have a short list. That’s basically correct, but there’s one significant complication.
Speaking of complications, what I’m portraying as a kind of linear/waterfall decision process of course usually involves lots of iteration, meandering around and general wheel-spinning. Real life is messy.
Simply put, there are many different kinds of application project. Other folks’ experience may not be as applicable to your case as you hope, because your case is different. So the rest of this post contains a checklist of distinctions among various different kinds of application project.
For starters, there are at least two major kind(s) of software development.
- Many projects fit the traditional development model, elements of which are:
- You — and this is very much a plural “you” — code something up more or less from scratch, using whatever language(s) and/or framework(s) you think make sense.
- You break the main project into pieces in obvious ways (e.g. server back end vs. mobile front), and then into further pieces for manageability.
- There may also be database designs, test harnesses, connectors to other apps and so on.
- But there are many other projects in which smaller bits of configuration and/or scripting are the essence of what you do.
- This is particularly common in analytics, where there might be business intelligence tools, ETL tools, scripts running against Hadoop and so on. The original building of a data warehouse/hub/lake/reservoir may also fit this model.
- It’s also what you do to get a major purchased packaged application into actual production.
- It also is often what happens for websites that serve “content”.
Other significant distinctions include:
- In-house vs. software-for-resale. If the developing organization is handing code to somebody else, then we’re probably talking about a more traditional kind of project. But if the whole thing is growing organically in-house, the script-spaghetti alternative may well be viable (in those projects for which it seems appropriate). Important subsidiary distinctions start with:
- (If in-house) Truly in-house vs. out-sourced.
- (If for resale) On-premises vs. SaaS. Or maybe not.
- Kind(s) of analytics, if any. Technologies and development processes used can be very different depending upon whether the application features:
- Business intelligence (not particularly real-time) as its essence.
- Reporting or other BI as added functionality to an essentially operational app.
- Low-latency BI, perhaps supported by (other) short-request processing.
- Predictive model scoring.
- The role(s) of the user(s). This influences how appealing and easy the UI needs to be.* Requirements are very different, for example, among:
- Classic consumer-facing websites, with recommenders and so on.
- Marketing websites targeted at a small group of business-to-business customers.
- Data-sharing websites for existing consumer stakeholders.
- Cheery benefits-information websites that the HR department wants employees to look at.
- Purely internal apps meant to be used by (self-)important executives.
- Internal apps meant to be used by line workers who will be given substantial training on them.
- Certain kinds of application project stand almost separately from the rest of these considerations, because their starting point is legacy apps. Examples may be found among:
- Migration/consolidation projects.
- Refactoring projects.
- Addition of incremental functionality.
*It also influences security, all good practices for securing internal apps notwithstanding.
Much also depends on the size and sophistication of the organization. What the “organization” is depends a bit on context:
- In the case of software products, SaaS (Software as a Service) or other internet services, it is primarily the vendor. However …
- … in B2B cases the sophistication of the customer organizations can also matter.
- In the case of in-house enterprise development, there’s only one enterprise involved (duh). However …
- … the “department” vs. “IT” distinction may be very important.
Specific considerations of this kind start:
- Is me-too functionality enough, or does the enterprise seek competitive advantage through technology?
- What kinds of technical risk does it seem prudent and desirable to take?
And that, in a nutshell, is why strategizing about application technology is often more complicated than it first appears.
- My November, 2015 post on issues in enterprise application software links to a number of other relevant posts.
- One of those (the same month) briefly surveyed actual choices in technology support for enterprise apps.
- A number of my posts draw distinction among different analytic use cases. An April, 2015 example points to some of the earlier ones.
- My July, 2012 categorization of kinds of BI is particularly relevant.
- A November, 2012 post focused on assessing the supposed need for speed.
- My September, 2011 strategic worksheet is evergreen.
In a companion introduction to Kafka post, I observed that Kafka at its core is remarkably simple. Confluent offers a marchitecture diagram that illustrates what else is on offer, about which I’ll note:
- The red boxes — “Ops Dashboard” and “Data Flow Audit” — are the initial closed-source part. No surprise that they sound like management tools; that’s the traditional place for closed source add-ons to start.
- “Schema Management”
- Is used to define fields and so on.
- Is not equivalent to what is ordinarily meant by schema validation, in that …
- … it allows schemas to change, but puts constraints on which changes are allowed.
- Is done in plug-ins that live with the producer or consumer of data.
- Is based on the Hadoop-oriented file format Avro.
Kafka offers little in the way of analytic data transformation and the like. Hence, it’s commonly used with companion products.
- Per Confluent/Kafka honcho Jay Kreps, the companion is generally Spark Streaming, Storm or Samza, in declining order of popularity, with Samza running a distant third.
- Jay estimates that there’s such a companion product at around 50% of Kafka installations.
- Conversely, Jay estimates that around 80% of Spark Streaming, Storm or Samza users also use Kafka. On the one hand, that sounds high to me; on the other, I can’t quickly name a counterexample, unless Storm originator Twitter is one such.
- Jay’s views on the Storm/Spark comparison include:
- Storm is more mature than Spark Streaming, which makes sense given their histories.
- Storm’s distributed processing capabilities are more questionable than Spark Streaming’s.
- Spark Streaming is generally used by folks in the heavily overlapping categories of:
- Spark users.
- Analytics types.
- People who need to share stuff between the batch and stream processing worlds.
- Storm is generally used by people coding up more operational apps.
If we recognize that Jay’s interests are obviously streaming-centric, this distinction maps pretty well to the three use cases Cloudera recently called out.
Complicating this discussion further is Confluent 2.1, which is expected late this quarter. Confluent 2.1 will include, among other things, a stream processing layer that works differently from any of the alternatives I cited, in that:
- It’s a library running in client applications that can interrogate the core Kafka server, rather than …
- … a separate thing running on a separate cluster.
The library will do joins, aggregations and so on, and while relying on core Kafka for information about process health and the like. Jay sees this as more of a competitor to Storm in operational use cases than to Spark Streaming in analytic ones.
We didn’t discuss other Confluent 2.1 features much, and frankly they all sounded to me like items from the “You mean you didn’t have that already??” list any young product has.
- My October, 2014 post on Streaming for Hadoop is a sort of predecessor to this two-post series.
