Don’t plan to fish in your personal data lake.
Perhaps the biggest mess in all of IT is the management of individual consumers’ data. Our electronic data is thoroughly scattered. Most individual portions are poorly managed. There’s no integration. The data that’s on paper is even worse. For example:
- Do you have access to your medical records? Do you even know when you were last vaccinated for what?
- Several enterprises have comprehensive records of all your credit card purchases, in easy-to-analyze form. Do you have such records too?
- How easily can you find old emails? How about old paper correspondence?
For the most part, the technology community is barely trying to solve those problems. But even when it does try, success is mixed at best. For example:
- People generally hate iCloud and iTunes. Even usability icon Apple can’t get its data management apps right.
- Intuit is divesting flagship product Quicken.
- Evernote seems to be in trouble, although there are evidently execution issues involved.
- How is Dropbox’s consumer business doing, especially from a revenue standpoint?
And those are some of the most successful names.
There are numerous reasons for this dismal state of affairs. Read more
It’s difficult to project the rate of IT change in health care, because:
- Health care is suffused with technology — IT, medical device and biotech alike — and hence has the potential for rapid change. However, it is also the case that …
- … health care is heavily bureaucratic, political and regulated.
Timing aside, it is clear that health care change will be drastic. The IT part of that starts with vastly comprehensive electronic health records, which will be accessible (in part or whole as the case may be) by patients, care givers, care payers and researchers alike. I expect elements of such records to include:
- The human-generated part of what’s in ordinary paper health records today, but across a patient’s entire lifetime. This of course includes notes created by doctors and other care-givers.
- Large amounts of machine-generated data, including:
- The results of clinical tests. Continued innovation can be expected in testing, for reasons that include:
- Most tests exploit electronic technology. Progress in electronics is intense.
- Biomedical research is itself intense.
- In particular, most research technologies (for example gene sequencing) can be made cheap enough over time to be affordable clinically.
- The output of consumer health-monitoring devices — e.g. Fitbit and its successors. The buzzword here is “quantified self”, but what it boils down to is that every moment of our lives will be measured and recorded.
- The results of clinical tests. Continued innovation can be expected in testing, for reasons that include:
These vastly greater amounts of data cited above will allow for greatly changed analytics.
I’m going to be out-of-sorts this week, due to a colonoscopy. (Between the prep, the procedure, and the recovery, that’s a multi-day disablement.) In the interim, here’s a collection of links, quick comments and the like.
1. Are you an engineer considering a start-up? This post is for you. It’s based on my long experience in and around such scenarios, and includes a section on “Deadly yet common mistakes”.
2. There seems to be a lot of confusion regarding the business model at my clients Databricks. Indeed, my own understanding of Databricks’ on-premises business has changed recently. There are no changes in my beliefs that:
- Databricks does not directly license or support on-premises Spark users. Rather …
- … it helps partner companies to do so, where:
- Examples of partner companies include usual-suspect Hadoop distribution vendors, and DataStax.
- “Help” commonly includes higher-level support.
However, I now get the impression that revenue from such relationships is a bigger deal to Databricks than I previously thought.
Databricks, by the way, has grown to >50 people.
3. DJ Patil and Ruslan Belkin apparently had a great session on lessons learned, covering a lot of ground. Many of the points are worth reading, but one in particular echoed something I’m hearing lots of places — “Data is super messy, and data cleanup will always be literally 80% of the work.” Actually, I’d replace the “always” by something like “very often”, and even that mainly for newish warehouses, data marts or datasets. But directionally the comment makes a whole lot of sense.

- Continuuity toured in 2012 and touted its “app server for Hadoop” technology.
- Continuuity recently changed its name to Cask and went open source.
- Cask’s product is now called CDAP (Cask Data Application Platform). It’s still basically an app server for Hadoop and other “big data” — ouch do I hate that phrase — data stores.
- Cask and Cloudera partnered.
- I got a more technical Cask briefing this week.
- App servers are a notoriously amorphous technology. The focus of how they’re used can change greatly every couple of years.
- Partly for that reason, I was unimpressed by Continuuity’s original hype-filled positioning.
So far as I can tell:
- Cask’s current focus is to orchestrate job flows, with lots of data mappings.
- This is supposed to provide lots of developer benefits, for fairly obvious reasons. Those are pitched in terms of an integration story, more in a “free you from the mess of a many-part stack” sense than strictly in terms of data integration.
- CDAP already has a GUI to monitor what’s going on. A GUI to specify workflows is coming very soon.
- CDAP doesn’t consume a lot of cycles itself, and hence isn’t a real risk for unpleasant overhead, if “overhead” is narrowly defined. Rather, performance drags could come from …
- … sub-optimal choices in data mapping, database design or workflow composition.
There are numerous ways that technology, now or in the future, can significantly improve personal safety. Three of the biggest areas of application are or will be:
- Crime prevention.
- Vehicle accident prevention.
- Medical emergency prevention and response.
Implications will be dramatic for numerous industries and government activities, including but not limited to law enforcement, automotive manufacturing, infrastructure/construction, health care and insurance. Further, these technologies create a near-certainty that individuals’ movements and status will be electronically monitored in fine detail. Hence their development and eventual deployment constitutes a ticking clock toward a deadline for society deciding what to do about personal privacy.
Theoretically, humans aren’t the only potential kind of tyrants. Science fiction author Jack Williamson postulated a depressing nanny-technology in With Folded Hands, the idea for which was later borrowed by the humorous Star Trek episode I, Mudd.
Of these three areas, crime prevention is the furthest along; in particular, sidewalk cameras, license plate cameras and internet snooping are widely deployed around the world. So let’s consider the other two.
Vehicle accident prevention

What will soft, mobile robots be able to do that previous generations cannot? A lot. But I’m particularly intrigued by two large categories:
- Inspection, maintenance and repair.
- Health care/family care assistance.
There are still many things that are hard for humans to keep in good working order, including:
- Power lines.
- Anything that’s underwater (cables, drilling platforms, etc.)
- Pipelines, ducts, and water mains (especially from the inside).
- Any kind of geographically remote power station or other installation.
Sometimes the issue is (hopefully minor) repairs. Sometimes it’s cleaning or lubrication. In some cases one might want to upgrade a structure with fixed sensors, and the “repair” is mainly putting those sensors in place. In all these cases, it seems that soft robots could eventually offer a solution. Further examples, I’m sure, could be found in factories, mines, or farms.
Of course, if there’s a maintenance/repair need, inspection is at least part of the challenge; in some cases it’s almost the whole thing. And so this technology will help lead us toward the point that substantially all major objects will be associated with consistent flows of data. Opportunities for data analysis will abound.
Most IT innovation these days is focused on machine-generated data (sometimes just called “machine data”), rather than human-generated. So as I find myself in the mood for another survey post, I can’t think of any better idea for a unifying theme.
1. There are many kinds of machine-generated data. Important categories include:
- Web, network and other IT logs.
- Game and mobile app event data.
- CDRs (telecom Call Detail Records).
- “Phone-home” data from large numbers of identical electronic products (for example set-top boxes).
- Sensor network output (for example from a pipeline or other utility network).
- Vehicle telemetry.
- Health care data, in hospitals.
- Digital health data from consumer devices.
- Images from public-safety camera networks.
- Stock tickers (if you regard them as being machine-generated, which I do).
That’s far from a complete list, but if you think about those categories you’ll probably capture most of the issues surrounding other kinds of machine-generated data as well.
2. Technology for better information and analysis is also technology for privacy intrusion. Public awareness of privacy issues is focused in a few areas, mainly: Read more
MapR put out a press release aggregating some customer information; unfortunately, the release is a monument to vagueness. Let me start by saying:
- I don’t know for sure, but I’m guessing Derrick Harris was incorrect in suspecting that this release was a reaction to my recent post about Hortonworks’ numbers. For one thing, press releases usually don’t happen that quickly.
- And as should be obvious from the previous point — notwithstanding that MapR is a client, I had no direct involvement in this release.
- In general, I advise clients and other vendors to put out the kind of aggregate of customer success stories found in this release. However, I would like to see more substance than MapR offered.
Anyhow, the key statement in the MapR release is:
… the number of companies that have a paid subscription for MapR now exceeds 700.
Unfortunately, that includes OEM customers as well as direct ones; I imagine MapR’s direct customer count is much lower.
In one gesture to numerical conservatism, MapR did indicate by email that it counts by overall customer organization, not by department/cluster/contract (i.e., not the way Hortonworks does). Read more

The genesis of this post is that:
- Hortonworks is trying to revitalize the Apache Storm project, after Storm lost momentum; indeed, Hortonworks is referring to Storm as a component of Hadoop.
- Cloudera is talking up what I would call its human real-time strategy, which includes but is not limited to Flume, Kafka, and Spark Streaming. Cloudera also sees a few use cases for Storm.
- This all fits with my view that the Current Hot Subject is human real-time data freshness — for analytics, of course, since we’ve always had low latencies in short-request processing.
- This also all fits with the importance I place on log analysis.
- Cloudera reached out to talk to me about all this.
Of course, we should hardly assume that what the Hadoop distro vendors favor will be the be-all and end-all of streaming. But they are likely to at least be influential players in the area.
In the parts of the problem that Cloudera emphasizes, the main tasks that need to be addressed are: Read more

We all tend to assume that data is a great and glorious asset. How solid is this assumption?
- Yes, data is one of the most proprietary assets an enterprise can have. Any of the Goldman Sachs big three* — people, capital, and reputation — are easier to lose or imitate than data.
- In many cases, however, data’s value diminishes quickly.
- Determining the value derived from owning, analyzing and using data is often tricky — but not always. Examples where data’s value is pretty clear start with:
- Industries which long have had large data-gathering research budgets, in areas such as clinical trials or seismology.
- Industries that can calculate the return on mass marketing programs, such as internet advertising or its snail-mail predecessors.
*”Our assets are our people, capital and reputation. If any of these is ever diminished, the last is the most difficult to restore.” I love that motto, even if Goldman Sachs itself eventually stopped living up to it. If nothing else, my own business depends primarily on my reputation and information.
This all raises the idea – if you think data is so valuable, maybe you should get more of it. Areas in which enterprises have made significant and/or successful investments in data acquisition include: Read more
