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

Everybody is confused about privacy and surveillance. So I’m renewing my efforts to consciousness-raise within the tech community. For if we don’t figure out and explain the issues clearly enough, there isn’t a snowball’s chance in Hades our lawmakers will get it right without us.
How bad is the confusion? Well, even Edward Snowden is getting it wrong. A Wired interview with Snowden says:
“If somebody’s really watching me, they’ve got a team of guys whose job is just to hack me,” he says. “I don’t think they’ve geolocated me, but they almost certainly monitor who I’m talking to online. Even if they don’t know what you’re saying, because it’s encrypted, they can still get a lot from who you’re talking to and when you’re talking to them.”
That is surely correct. But the same article also says:
“We have the means and we have the technology to end mass surveillance without any legislative action at all, without any policy changes.” The answer, he says, is robust encryption. “By basically adopting changes like making encryption a universal standard—where all communications are encrypted by default—we can end mass surveillance not just in the United States but around the world.”
That is false, for a myriad of reasons, and indeed is contradicted by the first excerpt I cited.
What privacy/surveillance commentators evidently keep forgetting is:
- There are many kinds of privacy-destroying information. I think people frequently overlook just how many kinds there are.
- Many kinds of organization capture that information, can share it with each other, and gain benefits from eroding or destroying privacy. Similarly, I think people overlook just how pervasive the incentive is to snoop.
- Privacy is invaded through a variety of analytic techniques applied to that information.
So closing down a few vectors of privacy attack doesn’t solve the underlying problem at all.
Worst of all, commentators forget that the correct metric for danger is not just harmful information use, but chilling effects on the exercise of ordinary liberties. But in the interest of space, I won’t reiterate that argument in this post.
Perhaps I can refresh your memory why each of those bulleted claims is correct. Major categories of privacy-destroying information (raw or derived) include:
- The actual content of your communications – phone calls, email, social media posts and more.
- The metadata of your communications — who you communicate with, when, how long, etc.
- What you read, watch, surf to or otherwise pay attention to.
- Your purchases, sales and other transactions.
- Video images, via stationary cameras, license plate readers in police cars, drones or just ordinary consumer photography.
- Monitoring via the devices you carry, such as phones or medical monitors.
- Your health and physical state, via those devices, but also inferred from, for example, your transactions or search engine entries.
- Your state of mind, which can be inferred to various extents from almost any of the other information areas.
- Your location and movements, ditto. Insurance companies also want to put monitors in cars to track your driving behavior in detail.

After visiting California recently, I made a flurry of posts, several of which generated considerable discussion.
- My claim that Spark will replace Hadoop MapReduce got much Twitter attention — including some high-profile endorsements — and also some responses here.
- My MemSQL post led to a vigorous comparison of MemSQL vs. VoltDB.
- My post on hardware and storage spawned a lively discussion of Hadoop hardware pricing; even Cloudera wound up disagreeing with what I reported Cloudera as having said. Sadly, there was less response to the part about the partial (!) end of Moore’s Law.
- My Cloudera/SQL/Impala/Hive apparently was well-balanced, in that it got attacked from multiple sides via Twitter & email. Apparently, I was too hard on Impala, I was too hard on Hive, and I was too hard on boxes full of cardboard file cards as well.
- My post on the Intel/Cloudera deal garnered a comment reminding us Dell had pushed the Intel distro.
- My CitusDB post picked up a few clarifying comments.
Here is a catch-all post to complete the set. Read more
From time to time I like to do “what I’m working on” posts. From my recent blogging, you probably already know that includes:
- Hadoop (always, and please see below).
- Analytic RDBMS (ditto).
- NoSQL and NewSQL.
- Specifically, SQL-on-Hadoop
- Spark and other memory-centric technology, including streaming.
- Public policy, mainly but not only in the area of surveillance/privacy.
- General strategic advice for all sizes of tech company.
Other stuff on my mind includes but is not limited to:
1. Certain categories of buying organizations are inherently leading-edge.
- Internet companies have adopted Hadoop, NoSQL, NewSQL and all that en masse. Often, they won’t even look at things that are conventional or expensive.
- US telecom companies have been buying 1 each of every DBMS on the market since pre-relational days.
- Financial services firms — specifically algorithmic traders and broker-dealers — have been in their own technical world for decades …
- … as have national-security agencies …
- … as have pharmaceutical research departments.
Fine. But what really intrigues me is when more ordinary enterprises also put leading-edge technologies into production. I pester everybody for examples of that.
IBM excels at game technology, most famously in Deep Blue (chess) and Watson (Jeopardy!). But except at the chip level — PowerPC — IBM hasn’t accomplished much at game/real world crossover. And so I suspect the Watson hype is far overblown.
I believe that for two main reasons. First, whenever IBM talks about big initiatives like Watson, it winds up bundling a bunch of dissimilar things together and claiming they’re a seamless whole. Second, some core Watson claims are eerily similar to artificial intelligence (AI) over-hype three or more decades past. For example, the leukemia treatment advisor that is being hopefully built in Watson now sounds a lot like MYCIN from the early 1970s, and the idea of collecting a lot of tidbits of information sounds a lot like the Cyc project. And by the way:
- MYCIN led to E-MYCIN, which led to the company Teknowledge, which raised a lot of money* but now has almost faded from memory.
- Cyc is connected to the computer science community’s standard unit of bogosity.
