Review: Second Generation Lenovo Carbon X1 with Linux

As a Christmas present to myself, I decided to get a new laptop. My second generation Dell “Sputnik” Ubuntu Edition is getting a little long in the tooth. The screen resolution of 1366×768 is a little confining, and I’ve never been in love with the trackpad.

Now, while most of the folks at The OpenNMS Group are Mac users, the freetards in the group tend toward the Lenovo X1 Carbon. As Eric says, when it comes to Linux laptops you can’t go wrong with Lenovo.

Well, apparently you can.

While I ordered my unit in late November, it didn’t ship until the new year. I got the shipping notice the same day they announced the second generation X1 carbon at CES. Since I wanted the new shiny, I called Lenovo (their customer support is located in nearby Raleigh and is awesome) and returned the unit before it arrived. I then ordered the new model with the the extremely high density “retina” display. It arrived last week and I started playing with it this weekend.

In short: do not buy this laptop if you like Linux.

While sleek and stylish, the first thing they broke is the trackpad (one of my main reasons for switching). Instead of discreet mouse buttons like most Thinkpads before it, it is a single unit. I found it very hard to get used to using the “pseudo” buttons. Plus, it is mechanical and it feels really clunking when you press down on it.

The next thing they broke was the keyboard. While I’m not sure if the top row is OLED or just OLED-like, the functions keys are now programmatically displayed and gone are things like volume and contrast (those do exist when booted to Windows 8). And while I don’t know if this is new, but the “backspace” and “delete” keys are right next to each other which I found annoying, as I would often hit the wrong one.

But I could live with that, as it is only a matter of time before someone starts doing something cool with that technology and I could get used to the keyboard. Here is why I’m sending it back:

  • Suspend Doesn’t Work: Well, technically, resume doesn’t work. The system will suspend, but the OLED top row never dims and the laptop just starts heating up as something is obviously still running. The pm-suspend.log shows an error free shutdown, but once “suspended” you have to hold down the power key until it turns off and then reboot.

    UPDATE: I got this to work, sort of. Once Hibernate worked I ended up using this post to determine the issue was with the xhci_hcd (USB3) driver. I disabled it and now suspend works. However, the network doesn’t come back nor do the function keys.

  • Hibernate Doesn’t Work: Since this is a solid state machine with something like an 8 second boot time into Linux Mint, I’d be okay if I could hibernate instead of suspend. However, hibernate is just a shutdown with no warning to save your work.

    UPDATE: I got this to work, sort of. Removed the encryption on the swap partition and then updated /etc/initramfs-tools/conf.d/resume to match the new UUID and then “update-initramfs -u” to re-read that file. The resume isn’t always flawless (when run from the command line the mouse never came back and once I had to bounce the network).

  • Backlight Doesn’t Work: I like having a backlit keyboard. You can see the backlight come on when booting, but it never comes on when running under Mint.
  • Fingerprint Sensor Doesn’t Work: While I don’t know how much I’d use this, the model in this laptop by Validity Sensors (USB device ID 138a:0017) isn’t supported under Linux yet.
  • Weird Power Issues: Sometimes the unit fan turns on for no real reason, like something with Linux and the power management are out of sync.

I took this laptop on a road trip and was very unhappy with all of the effort I had to put into a system that was just supposed to work out of the box. At one point in time I changed a BIOS setting that wiped out grub (I had left Windows 8 on the system in a partition) and Windows Bootloader took over and wouldn’t let me back in to Mint. I finally based the whole thing just to see if that might help (I had to turn of secure boot to get Mint on it in the first place and thought maybe some weird UEFI issue was at play) but it didn’t improve things.

So it is a very sad day for those of us who looked to Lenovo to provide us Apple-quality laptops for Linux. Snatch up those Generation 1 models while they last or check out the new Dell “Sputnik 3“, but don’t buy this laptop.


Back in December a friend of mine I met through OpenNMS offered up a Google Glass invite. While I have privacy concerns about the whole thing, I didn’t want to miss the opportunity to play with the technology, so I accepted.

Well, it took awhile, but this week Google got around to offering me the opportunity to become an “Explorer”. After putting in my code, the Glass was added to my Google Wallet shopping cart and soon on its way via overnight shipping to the office.

Unfortunately, I ran into a problem right out of the gate. Apparently Glass doesn’t fit my head. While the picture above looks pretty normal, in order to actually see the screen I have to do this:

And that is painful. I soon had a vicious headache that stayed with me until I went to bed.

The way the Glass display works is pretty cool. It sits in front on the right eye and consists of an optically clear rectangular solid (made of plastic I believe). I’m going to call it a “cube” for lack of a better word, even though it is twice as wide as it is tall so it isn’t officially one.

The left side of the cube is mirrored, and the LCD is actually located on the right side, perpendicular to the long side of the rectangle. In the middle of the cube, at a 45 degree angle, is some sort of optical material that serves as the actual “display” – light from the LCD on the right passes through it, hits the mirror and then gets diverted toward the user’s eye.

The right earpiece is also a touchpad and you can interact with the device by swiping your finger along it. You pair it via Bluetooth with your phone, and that allows the Glass to have network access, although you can connect it via Wi-Fi as well.

But to be honest I never got to play with many of the features simply because I could not see the damn screen very well. I called the support line to see if there was anything I could do to adjust the screen on the glass downward, much like the “heads up” display on my wife’s car can be adjusted vertically, but unfortunately if you can’t get it to work by adjusting the nose piece you’re out of luck. You can rotate the display slightly left to right, but that wasn’t my problem.

The return process seems pretty easy. I called Google and they are sending me a box and shipping label. Once they get it and confirm it is not damaged, they will refund my money (and considering that the only thing I took out of the box was the Glass itself I’m not expecting any problems).

To say I’m disappointed is an understatement. If the display could just be a little lower in my line of sight I would have experimented with it a great deal. I’ve even taken it out of the box no less than three times during the writing of this post to see if some adjustment would give me some relief, but all I got was a headache.

I hope the return box shows up soon so I’ll quit trying to play with it.

Happy Money

Happy Money

As someone who has dedicated most of his professional life to open source software, it may seem strange that I think about money a lot. With respect to the company, the decisions I make not only impact myself but all of our employees, and personally money provides a certain amount of comfort and security.

Awhile back I was reading on Dan Ariely’s blog about a new book called Happy Money. I bought it on impulse (which I found ironic) but it took me a little while to get around to reading it.

It’s my kind of non-fiction book, meaning that about a quarter of it is references for the copious footnotes. If you are planning to change my mind about something, it helps to be able to back it up. I am still blasted for my review on Amazon about Life, Inc. which made sweeping and sometimes nonsensical generalizations and the author just expected us to take his word for it (or more likely, he just wanted to make a buck by telling people what they wanted to hear).

The authors of Happy Money, Elizabeth Dunn and Michael Norton, start off with the premise that there are a lot of books out there that tell you how to make money, but few that tell you how to become happier with the money you have. Their book details numerous studies undertaken by them and others, and they found five main things one can do with money that can have a large impact on one’s happiness.

The first thing was to buy experiences versus things. The studies they cite show that people get a lot more happiness out of, say, a trip to an exotic locale than in buying something like a fancy car. While owners of expensive cars reports a higher level of happiness when thinking about the car itself, when thinking about the last trips they took most car owners report about the same level of happiness no matter what type of car was used. So if you are driving to the store in the rain behind a dump truck because you are out of milk, it doesn’t matter if you are in a BMW or a Kia.

One example given in this chapter are the Tough Mudder races. These events are hardcore obstacle courses designed by British special forces. People who complete the course report a very high level of personal satisfaction, and it is in part because these events require teamwork and thus the experience fosters a sense of connectedness with others. While buying a new TV is for the most part a solo experience, working with others to get over a 12 foot wall requires teamwork. There is a bond created among finishers that can’t be purchased.

I occasionally play the lottery. I never win, but I do it for the daydreams I can have while I wait to find out that I’ve lost (I file it under “entertainment”). My rule is that I can spend $1 for every $100 million in jackpot. My spouse and I have talked about what we’d do if we ever won big, and the recurring fantasy would be to move to someplace like Positano, Italy, for a year and immerse ourselves in the culture. Then we might move on to Germany, or Argentina or Japan. Our lottery fantasies rarely include a big purchase.

The second thing they talk about is making things treats. They credit the comedian Sarah Silverman for this wisdom. She loves “pot, porn and fart jokes”, but she insists that you have to make it a treat. To truly enjoy something it helps if it isn’t available all the time. To go back to the car analogy above, most car owners report the same level of happiness with their vehicles, but when asked about a time they drove their car just for the fun of driving it, those with more expensive vehicles reported a higher level of happiness even if it didn’t happen as often.

The book talks at length about this issue of how availability results in “diminishing returns”. One example is candy corn, which tends to be easily available only certain times of the year (the Internet makes year round acquisition of almost anything possible year round, but let’s discount that for now). Or, as I just saw on television, the McDonalds McRib sandwich, which comes and goes off the menu, is available again. There is even a McRib Locator website to help people find them.

One example that I experienced talks about how people are more likely to savor something if they learn it won’t last. I lived in Northern California from 1994 to 1995, and when we decided to move back to North Carolina we rushed to visit Monterey, Alcatraz, etc. even though we had months to do so before the moving deadline appeared. When access to something is presumed to be always available, people are less likely to use it.

The third tip presented is the idea of buying time. I never have enough time, but I’m also cheap and tend to do a lot of things myself. One thing we always did on Saturday morning was clean the house. A couple of years ago, when my bride’s career took off, I was talked into hiring a cleaning service that comes in every other week. While they don’t do the job as well as I would, they do give us back our Saturday mornings, and that time is worth much more than the money I spend on the service.

Studies have shown that wealthier people tend to feel like they have less free time. In my lottery fantasy, having lots of money would give me more free time, but this book points out that people, especially those in my position who bill out their time on a hourly basis, seem to have issues doing things that don’t directly result in revenue. Why take a walk along the lake if that time could be spent helping a client?

The solution suggested by the book is to find ways, such as volunteer work, in order to purposely give time away. Giving time away reduced the feelings that time not spent working is wasted time, and thus increases happiness.

Step number four is to “Pay Now, Consume Later”. In the US our culture is geared heavily toward “Get It Now, Pay Later” which both fosters consumption, such as a new TV, and adds a future burden of payment. Not only is the happiness created by the purchase fleeting, as covered earlier, the added onus of having to come up with money to pay for it later greatly decreases the pleasure obtained by getting the thing in the first place.

However, the anticipation of an event can increase its happiness. Prepaying for, say, a beach trip and then thinking about it as the date approaches provides more pleasure than the trip alone. The book refers to the example of a Virgin Galactic flight. A woman and her husband both dreamed of going into space but couldn’t afford it. Unfortunately, the husband died. His wife decided to use the insurance money to pay the US$250,000 for a seat on a Virgin Galactic flight.

While the time spent in space will be measured in minutes, she gets to experience a number of things before the trip that both increase the anticipation and add to her happiness. There are astronaut-only events, trips to view the test flights and the training for the trip itself.

In my own experience I can think of a number of things where the run up to the event was as fun as the event itself.

The final step was called “Invest in Others” that shows that people tend to get a lot of enjoyment out of spending money on others more than just on themselves (the most pleasure came from spending money on others while with them). They even discuss a study where pre-verbal children seemed happiest when giving things to others (have you ever visited a friend with a small child who insists on bringing you things like their toys?).

While the book gave me a lot to think about concerning my own life, I was happy to find that working with OpenNMS tends to hit on all five. Working with OpenNMS users has provided me with a number of amazing experiences around the world. Due to the fact that I’m almost always traveling, revisiting my favorite places is a treat, from macarons in Palo Alto to Schwarzer Hahn beer in Fulda. I do a crappy job of buying time, but as we grow as a company I’m trying to learn to delegate more. Just this morning we got a notification that the drink machine was low on Fresca, and Tina was there to take care of it instead of me. As for “pay now, consume later” I like to think that all the hard work we put into the company will pay off in the future, and it is exciting to see our product grow over time, and finally the whole basis of free software is the idea of sharing and helping others.

Happy Money is a short read if not an overly easy one, and if you find yourself focusing more on getting money than being happy, you should check it out.

Review: Sheryl Crow at DPAC

Another post for me to practice my typing, with no OpenNMS content, although some of you might find it interesting.

This weekend I went to see Sheryl Crow perform at the Durham Performing Arts Center. I remember the exact moment I got old, and that was at a concert as well. It was Sting with Natalie Merchant opening, and Andrea and I decided to leave during the encore to beat the traffic. Contrast that to watching The Boss at the LA Civic Center where we stayed until they kicked us out as we sat watching the roadies tear down the stage.

This concert also made me feel a little old, as we were at the lower end of the age demographic. I was introduced to Sheryl Crow’s music by my friend Bill Hinkle, but that was twenty years ago back in 1993. I didn’t realize that Sheryl was 51, several years older than me, and the average age of the crowd was higher than that.

Not that we old folks don’t know how to rock.

The main reason we went was that I managed to score fifth row seats. They were toward the left of the stage, but as I’ve grown older I’ve come to expect a little comfort when I go out. Sad, I know, and it is rare enough that I don’t go out often, but I think my stage rushing, general admission days are over.

The opening act was a trio headed by Dustin Lynch. He was accompanied by another acoustic guitarist and a pretty blond woman on fiddle. The set was kind of forgettable, but I can remember thinking to myself “Do I like this guy enough to steal his music?”

I didn’t.

I also thought it was funny that the cameraman kept the camera on the blond through most of the set, even when she wasn’t actively doing much.

He tried to pander to the audience, bringing up references to our troops overseas, God, etc. Not that I mind those aspects of country music but it came across as patronizing. At one point he launched into a bit about how all the men in the audience where there because their woman dragged them to the concert, and Andrea and I were both like “wha?”. First, I got the tickets, and second, it’s Sheryl Freakin’ Crow, known to appeal more to men than women on average.

Anyway, the main event started about 9pm. Sheryl came on stage with a custom red, white and blue guitar and a rocking band consisting of two other guitarists, a drummer, a bass guitarist, a woman on keyboards (married to the bass guitarist, we learned later) and another keyboardist/slide guitar/jack of all trades guy to round out the group.

It was a pretty good show.

She is a tiny woman – even in platform shoes with five inch heels she wasn’t very tall, but her voice is still huge.

The theme seemed to be fresh guitars, as there were new ones swapped out almost every song. I’m not sure if Sheryl uses a unique tuning for each song, but it was kind of fun to keep count of the different instruments. At one point she played something that I think was a baritone mandolin, something I’ve never seen before, but it had eight strings and a shape that seems to suggest a mandolin on steroids.

She did the hits and a number of new songs. They also did a couple of covers, including “Don’t Bring Me Down” by ELO and they ended the show’s encore with Led Zeppelin’s “Rock ‘n Roll“.

My biggest complaint was with the sound. Lately, every show I see, the vocals just aren’t mixed right, and you simply can’t make them out. Luckily I was familiar with enough of her music that it didn’t ruin the show.

While she is going for more of a country flair vs. rock in her later music (not a bad business move in my opinion) one song that I think will be a hit, maybe even a crossover hit, is “Shotgun”.

With the lyric:

Drive it like it’s stolen,
Park it like it’s rented,
What’s the use of money,
If you ain’t gonna spend it?

I was sold. Here’s a clip I found of it, and at least the part of the band on the front row was with her in Durham.

It was a fun evening. The DPAC is a great place for shows, and even though there was a Bull’s game going on at the same time, it was pretty easy to park and leave. Of course, I did have one chore to do before leaving.

Review: The Ocean at the End of the Lane by Neil Gaiman

Note: I don’t think there are spoilers here, but if you are overly sensitive, don’t read on.

I think it was Ben that introduced me to Neil Gaiman. Actually, that isn’t true. Howard let me read his Sandman comics in college, as long as I was careful and I read them in his dorm room. He didn’t have many, since they had just come out, but as someone who always thought comics books were only about super heroes, I found them fascinating. But I still thought about them as comics and not books, and so I focused more on the “Sandman” part than the “author” part, as much as I still think of “Superman” and “Batman” and not the people who make the stories and the pictures.

So I guess it was still Ben who introduced me to Neil Gaiman the author. The book was American Gods and it was spectacular. Amazing. I read it and then immediately re-read it. It cemented me as a Gaiman fan forever.

From there I read Neverwhere, and I can never ride the London Underground without thinking about it. Then there was Stardust, which I liked but it didn’t “wow” me. And I realized I had read him as a co-author since I had read Good Omens, but I remembered more the Terry Prattchet side of that novel.

I was very eager for his post-Gods work, and I bought Anansi Boys the day it was released. It was solid, but while Gods was an elaborate, multi-course meal, Anansi Boys was more of a well crafted dessert. I began to wonder if Gaiman had peaked. That would be nothing to be ashamed of, since American Gods is a masterpiece, but I wondered if it would be the masterpiece.

So I bought The Ocean at the End of the Lane sight unseen and got it the day it was released. The first thing that hit me was the slimness of this book. It is tiny. It weighs in at a mere 181 pages. I don’t own many hardbacks that small, and I just looked up Damage by Josephine Hart, which I thought was small, and it clocks in at 208 pages. While 27 pages doesn’t sound like much, that is a full 15% of Ocean.

I figure I’ll be vilified by at least one of my three readers for harping about the size of this book, but I feel that when writing a review the reader needs to understand my biases, and I was expecting a full novel and not a novella. And let’s be clear, this is a novella. There is one story plot told from a single point of view where most of the action takes place over a couple of days. The problem is that there is no market for novellas, yet someone with Gaiman’s star power can manage to sell one as a novel.

Despite that, it is a brilliant story. It is told from the point of view of a seven year old boy who lives in Sussex. After an unfortunate death, he starts to experience strange events. In trying to understand them, he is introduced to a family that lives on a farm down the lane from his house. The family consists of three women: one old, one young and one middle aged (an obvious reference to the Fates). The youngest one, Lettie, takes him on an adventure to help solve these strange events with dire consequences.

Gaiman is a great storyteller, and while I enjoyed the whole book I couldn’t help but be disappointed. I think he has done so many children’s books and screenplays in recent years that the long form eludes him. It would be nearly impossible to craft a novel on par with Gods with all of the different projects in which he is involved. In reading the on-line reviews, many state proudly “I read it in one sitting!”. Well, who couldn’t? This is pretty much a children’s book with one or two young adult scenes, and I thought I was getting an adult novel I could sink my teeth into.

Fanboys prepare your flame throwers.

I will probably buy anything he writes, but for the next one I won’t pre-order it. I’ll wait and see what it is, and I’ll try to set my expectations properly.

Review: The HWg-STE Ethernet Thermometer

Soon after my review of the AKCP Sensorprobe, I was contacted by Jan Rehak of the HW Group in the Czech Republic. I was asked if I would review one of their SNMP-based sensor units. I replied “of course” as I thought it was cool that anyone would want to send me an evaluation unit of anything, and I wanted to embark on my new career as super-duper, top-notch web reviewer-guy (are you listening, Telsa Motors?).

A few days later I received an HWg-STE Ethernet SNMP Thermometer, which is their most popular unit.

The HWg-STE supports two sensors, and it comes with one for temperature. The cable is pretty long so it can be placed some distance away from the unit. The unit is very compact, and molded into the case on the top and bottom are places for mounting screws. I installed it on the wall in the server room next to the Sensorprobe2.

One of the things I liked about the description was that it said it supported Linux for installation. Like most units of this type, the main configuration is done through a built-in web server, but a lot of vendors ship a small application to aid in the initial setup. The HWg-STE shipped with a CD that was Windows only (same as the Sensorprobe2) but I was able to find a Linux version on their website.

Unfortunately, I was unable to get it to work under Ubuntu 13.04, which is my current desktop at work. The application launched but failed to find any sensors. I did install the application via the CD on a Windows 8 machine we have in the office and it located the unit with an IP Address of I changed it to match our LAN addressing scheme and then did everything else from my desk using a web browser.

Once on the network, setup was a breeze. The webUI is very clean and easy to navigate. I was able to label the sensor which was also reflected in the data I was able to receive via SNMP.

Both the HWg SNMP MIB and a short OID description document are accessible from the “System” menu of the interface. The HWg-STE does support the ability to send e-mails when a threshold is reached, but I was a little disappointed with the lack of SNMP trap support. Also, like many devices like this, it only supports SNMPv1 – an SNMPv2 GETBULK request will fail. Like the Sensorprobe2 there is no IPv6 support.

It was pretty easy to add the device to OpenNMS for datacollection (and the configuration will be included in version 1.12):

The values returned are close to the values reported by the Sensorprobe2:

I don’t have any way to determine if one is more accurate than the other, but they both seem to be close enough for the accuracy needed to monitor a server room temperature.

Overall, I really liked the size of the HWg-STE and the look of its interface, but the missing SNMP trap support is frustrating. I would also like to see more information in the MIB, such as high and low thresholds, so that those can also be graphed. Proper SNMPv2 support as well as IPv6 support would be nice, but as much as I like IPv6 I am not seeing it as a requirement in the marketplace at the moment.

UPDATE: Jan wrote me back with some clarifications.

Of course we have other devices with SNMP Traps & more detailed MIB. But you know, product segmentation..

Our main product is the Poseidon family
Many more sensors, I/O, etc..

Yes we plan SNMP v3 + IPv6 to new generation Poseidon2.

Review: Ingress by NianticLabs@Google


This is a review of the augmented reality game Ingress, and contains no OpenNMS content. Ingress combines a massively multi-player on-line game with geocaching, and it can be quite addicting. I’ve spent a lot of time this week going from Level 3 to Level 4, and while I enjoyed it I don’t have enough interest to spend a lot more time on it. I do find some of the civil libertarian issues it raises, such as citizen access to public spaces, interesting. Currently Android only, it is a great example of how not all cool things are invented by Apple.


The backstory is the weakest part of the game. It goes something like this: an alien race called the Shapers appear on Earth, and with them, portals. Portals are gateways to another dimension, etc. that leak something called “exotic matter” or XM. You pretty much need XM do to anything.

This event has caused the world to divide into two factions (three, if you count those that don’t give a flip). One, the Enlightenment, wants to spread the influence of XM in order to take humans to the next evolutionary level. They are the “green” team. The other, the Resistance, seeks to limit the influence of the aliens because they fear it is harmful. They are the “blue” team.

Why I think this is weak is that it really doesn’t affect game play at all. Each team uses the same items and methods for similar objectives: the creation of control fields across the land. The idea is that all of the people (mind units, or MU) under the fields are either protected from the alien influence (in the case of a blue field) or more prone to enlightenment (in the case of a green field). Estimated world totals of MU by factions are displayed in the app.


Okay, the key to everything are those portals. Portals are placed by Niantic and are usually associated with public places such as post offices, fire stations, and libraries. In North Carolina with have a system of historic markers, and it looks like they have imported the whole database in order to place portals. In order to interact with a portal, you have to be next to it (for the most part). Hence the geocaching aspect of the game – you physically have to visit places in order to do anything. Note that tie-ins with companies like Zipcar and Jamba Juice have added those locations as portals as well, so it isn’t limited to just government buildings but instead the only rule is that they are supposed to be publicly accessible (which is stressing the definition in some cases).

The way you interact with the world of Ingress is with your scanner – i.e. the app on your Android phone. Combining the GPS and Google Maps, when you are close to a portal it will show up on your scanner. Your position is represented by a little arrow icon, and your area of influence is represented by a circle around that icon.

XM is represented by little, blobby white dots. Once those enter your influence, they will fly toward your icon and increase your XM totals. They can be found anywhere, but tend to cluster near portals.

Portals show up as smoky/glowing/other-worldly columns. Those controlled by the Resistance show up as blue, and those owned by the Enlightenment show as green. Uncaptured portals are gray.

In order to capture an uncaptured portal, you first have to be in range. Then you place an item called a resonator on the portal and then your faction will own it.

Completing actions earns you Action Points (AP). This is similar to “experience points” in other games. The more AP you collect, the higher your access level. Most items in Ingress have a level associated with them, and the higher your player level the more items you can use. At the moment the lowest level is L1 and the highest is L8.

There are seven things you can do to a portal. First, you can “hack” it. This is the main “farming” task in Ingress. Hacking a portal will give you items most of the time (sometimes you get nothing). Once you hack a portal you can’t hack it again for 300 seconds, and there is a limit to how many times you can hack a particular portal in a given amount of time – I think it is currently four times in a 24 hour period but I’m not sure. If you try to hack a portal before you are allowed, your scanner will display a “portal running hot” message with the time you must wait until your next attempt. If you have exceeded all attempts for the day, you get a “portal overloaded” message with no time displayed.

The next thing you can do to a portal is place a resonator, assuming the portal is uncaptured or belongs to your faction. There are eight spots for resonators at the cardinal points around the portal. A single player can place up to eight L1 resonators, but only 4 L2 or L3 resonators, etc. The higher the average level of resonators, the higher the level of the portal and the more energy it can store.

If a portal is fully populated with resonators, you can link it to other portals, assuming you have an item called a Portal Key. By hacking portals (of any faction) you can collect multiple copies of these keys. If you are at one portal and you have the Portal Key for another nearby portal, and both portals are owned by your faction, you can attempt to link them. Whether or not you are successful depends on the distance between the portals and whether or not there are any other links in the way (links cannot cross). The higher the level of the portal, the longer the link can be. The Portal Key is destroyed when the link is created.

Now the big thing to do is create a control field by linking three portals in a triangle. This results in a lot of AP and on the “intel map” the underlying area will show up as being controlled by your faction.

So, that’s three things (hack, place a resonator and link). The fourth is the ability recharge a portal. Portals hold Energy proportional to their level, but that energy is constantly draining, especially in the presence of links and fields. In order to keep the portal from decaying totally and becoming uncaptured, it has to be recharged. You can recharge it from your XM reserves if you are next to it (and it belongs to your faction) or remotely if you have a Portal Key.

The fifth is that you can upgrade the deployed resonators to ones of a higher level.

The sixth is that you can “target” a portal. All this does is show the distance and direction to the portal on the scanner.

All of these, except hacking and targeting, assume your faction owns the portal or it is uncaptured. The final thing you can do is attack a portal. To do this you need an item called an XMP burster. These are farmed through hacking and are single use. The higher level bursters do more damage, of course, and are used first in an attack. The more Energy a portal has, the longer it will take to destroy. A user for the faction that controls a portal can recharge it during an attack assuming they have XM and are either nearby or in possession of a Portal Key.

Position when using XMP busters is important. Like Phasers, they do more damage close in, so you will want to position yourself next to the resonator when using them. Once all the resonators on an enemy portal are destroyed, it becomes uncaptured and you can then deploy resonators to claim it. Note that hacking and attacking enemy portals are frowned upon by the portals themselves, and they will zap you with an XM draining bolt. When your XM gets too low, you won’t be able to hack, and when it gets even lower the scanner will stop operating until you find more. Being drained of XM does not appear to kill your character.

There are some other aspects of the game. On the Niantic website they drop clues to figuring out passcodes that can be entered into the scanner to receive XM, AP and items. There are power cubes of XM that you can find. But basically the idea is to capture unclaimed portals, destroy enemy portals, create links and control fields.

My Experience

I was first exposed to Ingress through Michael Shuler on G+. I didn’t really understand it more than it was a geolocation game. I strain to call it augmented reality, since you don’t actually see these portals through a camera but instead on a map, but since it was (and still is) a closed beta I didn’t pay too much attention to it.

Then at the OpenNMS Users Conference I saw how interested Alex Finger was in the game, and I decided to apply for an account. He was on the green team so I was determined to be blue just to be contrary, but he pointed out that most of the area where I live is blue, so I should be green just to have something to do. It was a great piece of advice, since you can’t change factions and I later learned that my friend Donnie Springfield was also on the green team and he’s local.

A few days later I got an account and started playing with it, but it didn’t really take off until Eric Evans came to the main OpenNMS office for the week and really showed me how to play it. He is on the blue team, so we made a bunch of jokes about “smurfs” and “frogs” but as I mentioned before the backstory really doesn’t matter – it’s still capture the flag.

The week I spent with Eric and for the weeks after I started playing more. I found myself going out of my way to visit portals. I attacked and captured my first one. I visited portals while traveling for OpenNMS. As I started closing in on Level 4, Donnie showed me how to look for uncaptured portals on the Ingress Intel map. You have to zoom in real close so it can be tedious, but when I discovered a cluster of seven(!) uncaptured portals nearby, I headed out into the country in the early morning rain to start farming AP to level.

When I found myself in a light sprinkle, knee deep in a cow pasture straining to get a data signal so I could fling a resonator out to that remote portal – I knew I had a problem.

I hit Level 4 this morning and I’m going to back way off for awhile. First of all, I’m too busy for such games. Second, even though being at a higher level is fun, nothing in the game play really changes. It takes 70K AP to reach L4, and 1.2M to reach L8. No matter how long a link you create, you get 313 AP. A link that creates a field gets you 1250 more. Hacking an enemy portal gets you 100 AP. That’s a lot of play to reach 1.2M (see the Wikipedia article for more complete info)

When I drive I do find myself hitting the brakes when I see a historic marker or a flag.

I think the game play could be improved by increasing the AP for longer links/bigger fields, or better yet, put the “multi” back in multi-player and have groups of people get more abilities when they work together (I’ll form the head).

I am curious as to the bandwidth requirements of this game, especially if they make it a truly augmented reality app. As I fly by at 60 mph in my car with Ingress running, I can’t imagine the amount of data that would have to flow to keep up. Multiply that by thousands if not millions of others and you have a cool engineering challenge.


I was in San Francisco a few weekends ago and was meeting Geoff Davis for dinner near 24th and Mission. It’s not a bad neighborhood but it isn’t exactly great. I got there early so decided to spend the time hacking the numerous portals in the area. At one point I looked up and found myself in an alley, narrow walls surrounded by some pretty amazing graffiti, but not exactly the safest place to be in the evening carrying around a couple of grand in electronics.

Trust me – in many places wandering around in circles while constantly looking at your phone is not considered normal. Since many if not most portals are near public buildings, in this post-9/11 world expect to be questioned if not threatened.

As I was attacking the fire department portal this week, I had to wander around back to get close to that last resonator. When it died I let out a little “whoop” and turned to see three rather large firemen looking at me all unfriendly-like, and one asked “May we help you, sir?”.

I laughed, told them I was playing a computer game, and showed it to them on my phone. They thought it was pretty cool.

Compared to actual geocaching, Ingress doesn’t require anything to be left on the property or anything to be dug up, etc.

I got a different experience last evening when I was attacking the post office portal. The postmaster, a tall, somewhat severe lady, was taking out some trash so I made sure to say “hi” and let her know what I was doing. She wasn’t happy and suggested that it was illegal for me to be outside of the “public” areas of the post office building. Now, I was under the impression that any area outside of a post office was public, and since I wasn’t interfering with business nor destroying property that I had every right to be there. I spent some time last night doing research and I think I am correct. First off, the idea of “trespassing” is predicated on there being “no trespassing” signs clearly posted. There is an “Authorized Vehicles” sign but nothing about “Authorized Personnel”.

It started to piss me off, and indicates one problem I have with this country. People at all levels of government seem to have forgotten that they serve at the will of the people, and especially at the lower levels, from TSA employees to rural postmasters, seem to want to claim more authority than they really have.

Now I’m not saying she shouldn’t have asked about a weird guy acting strangely next to a government building, but once explained I was hoping she’d have the cool and friendly reaction of the firemen. Instead, she decided to fluff up her feathers and imply it was verboten. Part of me wants to force the issue but the lazy part of me wants to pick a different battle.

Which brings me to the name “Ingress”. I think it is brilliant. Not only does it refer to “signal leakage“, such as the portals “leaking XM” into our world, but also property law, as in the rights of a person to enter a property.

If you are into this sort of thing, and you have an Android phone, I encourage you to check it out. In any case, I think Google has a hit on their hands.

Review: Existence by David Brin

I think it was during my extremely short collaboration with Harlan Ellison that I was introduced to the term “Speculative Fiction“.

When I was growing up in a little town in North Carolina, I fell in love with what we called Science Fiction. I devoured Asimov and Niven and Pohl, and while the local library held little in the way of such books, I spent the money I made mowing lawns on books from the Science Fiction Book Club, one of those mail order (I originally wrote “on-line” – sigh) “Book of the Month” companies that sold cheaply printed hardbacks at a discount. They also included a genre called “Fantasy” which included Tolkien, Zelzany and others.

As the Science Fiction and Fantasy genre grew, a new subgenre of books and stories arose that were much better defined by the term Speculative Fiction, although that term currently acts as an umbrella over all sorts of writing including horror and alternate histories. Descendants of the “hard” science fiction of Asimov, speculative fiction strives not only to entertain, but to predict. The plots of these stories tend to arise out of reactions to changes in technology, and they differed from regular Science Fiction by increasing the “plausibility” of the scenarios they portrayed.

One of my favorite books of this sort is the 1989 novel Earth by David Brin. Brin is probably best known for his Uplift series of novels. In them, the Earth is contacted by a large interstellar community of beings, ranked by their age and the number of beings they have “uplifted” into sentience. This uplifting service is not without a price: the uplifted species is indentured to a long period of service to the uplifting race. This can be quite profitable, so the competition to find potential species to uplift is fierce. When Earth is contacted, the human race has already uplifted dolphins and chimpanzees, which prevents them from becoming indentured, but this form of “bootstrapped” sentience is unknown in the galaxy and so the other races are suspicious, and some become downright hostile. What I love most about the books is the imagination that went into creating the different alien species. Imagine a life form made up of stacked rings, where each ring is a small chemical plant? Different combinations of rings produce different types of individuals. That’s just one of the many aliens that populate these books.

In the novel Earth, Brin put that imagination to use by setting it 50 years in the future. I’ve purchased a number of copies of that book over the years to give away just because of the number of predictions that have come true, such as the Internet, global warming and the erosion of privacy. There is a strong focus on the environment that I knew would appeal to several of my friends.

In Existence, Brin returns to those roots with a massive 800+ page novel that takes place roughly 40 years from now. It will be interesting to see which of his predictions comes true from this book.

Like Earth, the book is a little hard to start. He has a cast of characters that would make George R. R. Martin blush, and it wasn’t until about page 100 that I really got into it.

The book starts off with Gerald Livingstone, an astronaut/janitor tasked with clearing out space junk. Using an electromagnetic tether tens of kilometers in length, his job is grab onto space junk and fling it into the atmosphere so it will burn up before colliding with something important. Only this time he grabs an unknown object, an object of extraterrestrial origin, that causes great shifts in power and culture on Earth.

All of this takes place on an Earth that *could be*.

The main theme, and hence the name of the book, involves the extinction of the human race. One answer to the Fermi Paradox, which asks the question “if the likelihood of extraterrestrial intelligence is so high, why hasn’t it contacted us?” is that all species that approach the ability to travel across space end up self destructing. This book examines numerous scenarios that would cause that, and the possibility to avoid them.

One scenario is that we blow ourselves up. There is a quote from the book:

One sage who helped build the first atom bomb put it pun-gently “When has a man, bloody down to his soul, invented a new weapon and foresworn using it?”

Think North Korea and a possible US response to the use of nuclear weapons.

Another scenario is that we turn inward. In the wonderful non-fiction book 1493, I learned about the Chinese explorer Zheng He, who is also mentioned in Extinction. China had a technologically advanced civilization centuries before the West, but they rarely ventured outside of their borders. In one exception to that, Zheng He took a huge fleet of ships around the Pacific and Indian Oceans, but with the death of his Emperor those stopped. Perhaps that will happen to the human race, we’ll turn inward and stop looking out.

It is hard to write about the book without spoilers, but I am going to try not to give away the plot. Like many of his books, it reads like a thriller, which makes the presentations of all of these doomsday scenarios and ways to avoid them pretty entertaining. Once I got past page 100 I couldn’t put the book down.

It also happened that I was reading it while on holiday on the island of Roatán off the coast of Honduras.

The ocean plays a role in many of his works, and I liked reading about dolphins while being near them. One of my criticisms of the book is that there are a number of story lines that just seem to end. One involves the Uplift Project for dolphins, so in a small way this book could serve a prequel to that series, but I see it more like J.J. Abrams reimagining of the Star Trek universe than a true prequel, as Uplift aliens don’t play a role.

He does address one of my concerns, although not thoroughly. As this viral video explains, the distribution of wealth in the United States is getting heavily skewed.

Now I am certain that at least two of my three readers are thinking, “Yeah, but in American anyone can aspire to be in that 1%”. The truth is that it is becoming much harder, as factors such as contacts made while in school and family heritage start to erect barriers toward crossing into that zone where 1% of the population controls 20% or more of the total wealth. In other words, it ain’t based on merit and hard work any more. The political system has been gamed to make sure that percentage stays right where it is, if not increasing.

What usually happens in periods when a society’s wealth is skewed like this is revolution. The poor, with nothing to lose, simply take from the rich. Now, as Brin puts it in his book, the surveillance state may be able to locate a stop a potential Robespierre, but there are plenty of scenarios where no amount of surveillance could stop a revolution from happening.

In Existence, there was a cataclysmic event called “Awfulday” that isn’t described in detail, but it resulted in something called “the Big Deal”. The world was classified into 12 “Estates”, or castes, and rules were put in place to insure a smooth interaction between Estates in order to avoid such a revolution. The First Estate is made up of the wealthy, but instead of being in the 99%, these people measure there wealth in seven to eight “9s”. They play a role in the plot of the book, and although he doesn’t offer any real solutions toward wealth inequality, the Big Deal does offer some ways to mitigate it.

I enjoyed this book immensely and would recommend it to anyone who likes these sort of things. I do have some criticisms, however. When you hit Part Seven, there is a large gap in time between it and Part Six. Since this is on page 663 of the book, Brin can be forgiven for wanting to wrap things up, but I found the transition jarring. Plus there were a number of story lines that just seem to peter out. While it was important to describe the kinds of activities those of the First Estate would be able to engage in as technology progresses, for example, it would have been nice to have some sort of way to bring those stories back into the conclusion instead of dismissing them.

But that could also be just a personal bias. The main criticism I receive about my writing is that I’m too detailed and I want to explain everything, and part of the magic is to leave some up that up to the reader. But in this case I think Brin just got tired. This had to be a hard book to write, as there are hundreds of ideas here, each one a “noggin’ scratcher” and could drive a story in its own right.

The only thing I found missing was a thought I had about fixing the issues that plague us today. Note that when it comes to things like the environment, I’m not a “Save the Earth” kind of guy, but more of a “Save the Humans” kind of guy. I think the Earth will always find a way to support life until the sun swallows it up in several billion years. Almost every issue we have facing us is due to too many people being on the planet. In Earth there is an organization that wants to take this to the extreme, where they estimate that the carrying capacity for humans is around 400,000 people, and they have come up with plan to sharply decrease the number of humans to make it closer to that goal.

As purely a thought experiment I wonder: what if we sterilized 99% of all humans on the planet today (randomly, of course, to avoid any taint of eugenics)? Assuming it could be done, we would take the current population of seven billion down to seventy million in about 80 years – about twice the size of the Tokyo metropolitan area. Imagine today’s resources spread across so few people. I can’t help but think it would be a paradise. Of course the path to getting there would be hell – toward the end of that span you’d end up with billions of elderly supported by a small amount of youth, and the drive to reproduce is so ingrained in our genes that most would find the idea abhorrent on moral grounds (There is also evidence to suggest that the world’s population will start to plateau but even if that happens at the ten billion mark, that is still a whole lot of people).

If I had a fraction of the talent of Brin, there would be a book in that idea.

The AKCP SensorProbe2

While spring has been late coming to North Carolina, I expect our hot summers to be here soon, and that always causes concern as the air conditioner for the server room sometimes has issues keeping up. I used to use the temperature sensor in our ancient APC UPS, but I think the SNMP unit on that device has gotten a bit wonky and it tends to “stick” at a particular temperature.

One of our OpenNMS partners in Germany, Didactum, recommends sensor units from a company called AKCP. When I was there for the OpenNMS Users Conference I asked him if I could buy one, and he was kind enough to donate a SensorProbe2.

This is a small unit that you can mount on a wall and it supports up to two sensors. It shipped with a temperature/humidity probe and Roger added a water sensor (in case of flooding). Each sensor plugs into the unit via an RJ-45 connector.

It comes with a setup disk that is Windows only, but I decided to connect to its built-in web server over the network. The default IP address is, so I just set my address to and connected to it via a crossover cable.

The web page is plain but functional, and it was easy to change the IP and set up my unit.

Of course, we supply the default configuration for these units with OpenNMS, so all I had to do was discover it and I started to get graphs, automagically.

I also set up the OpenNMS server as a trap destination in case any of the thresholds are met. I’m hoping I don’t ever see those events but it is nice to know that I’ll have some indication if there is an issue with the environment in the server room. Thanks to Roger and the team at Didactum for making that happen.

Salesforce – A Cautionary Tale

When OpenNMS was small, we maintained our customer lists and sales prospects in a spreadsheet. As we grew, this didn’t work out so well, so we needed some sort of CRM solution.

As open source fans, we turned to SugarCRM, but the “community” version was a little hard to maintain. Unlike OpenNMS, they didn’t bother packaging things, so upgrades were a pain, and we found the application a little wanting in other aspects. The person in charge of sales suggested Salesforce, so against my objections we tried them out.

What were my objections? Well, first, I distrust putting company sensitive information into “the cloud”. I think the regulatory structure necessary to protect consumer data is horribly lacking and I didn’t want our clients, potential clients, revenues, etc. to be in someone else’s system. But that would be an issue with almost any hosted solution, so another of my objections was the price. Salesforce is designed for companies with teams of sales people – people who log in at the start of the day and log out at the end. We found out that our sales tend to be quite technical, so our sales guys are also engineers and product managers. The guy who is primarily concerned with sales probably doesn’t log into Salesforce every day, and I log into my account seven or eight times a month – tops.

But I am also a pragmatist. As someone running a company that survives by being profitable, I have to be. So when Salesforce seemed to be the best option, we went ahead and signed up. Other than the price and some small security concerns (I think Salesforce makes an honest effort to protect client data) I was satisfied. It’s just like when one of my guys wants a MacBook – I am moving away from Apple gear but I am not going to impact their productivity because of my personal bias.

A short while ago, I got an e-mail from the account manager at Salesforce:

I noticed you had signed the previous Salesforce contract. David had contacted Salesforce about adding licences, do you know if this was still the case? I ask because the discount I was going to apply for the net new discounts expire shortly.

This pissed me off for a couple of reasons. First of all, if David, the president and COO of the company, is the contact, deal with him, not me. It’s kind of like a small child running to Mom when Dad says “No”. Second, I hate (detest, despise, abhor) hard sell tactics like the “discounts expire shortly”. What? Salesforce has some extra accounts that are going to go bad, like a brown banana, if you don’t order before midnight tonight? It’s not like there are only a certain number of accounts available, and once they are gone, they are gone. I figured that ol’ Arunan was obvisouly B-team sales material.

In any case I asked David what was going on. We are growing a lot in 2013. We are formally opening the Georgia office and we plan to open three more offices by the end of the year. We’re hiring due to increased demand and that has led to the need for more account management. He was looking to add a couple of Salesforce accounts so that we could put more people into a part time sales role.

The key word being “part time”. Even the discount prices that Arunan was offering were too much for what we were getting. We figured we’d either make do with our current accounts or switch to something like SugarCRM (their hosted service is half the cost of Salesforce and it looks like their “community” version has gotten a lot better, including the upgrade process).

I wrote back to Arunan and said that we would not be getting any more licenses, and that we would probably be switching to something else before our contract expired in July. He replied:

Thanks Tarus for the note. Please make sure to call 415-901-8457 to log your cancellation notice so they can turn off the auto-renew on your contract.

Dave, it was a pleasure speaking with you the other day, and until the summer I will continue to be the Account Manager, so please do not hesitate to call or email when you need me.

Nothing offensive there. I would have probably asked why we were switching, if just to have a data point that some sort of smaller cost plan was desired by some Salesforce customers. I didn’t think much about it. Until the next day when I got:

You don’t have to worry about calling Billing. I’ve put in the cancellation for you – the case # is xxxxxxx for your records. Your account will not renew and your licenses will delete this summer. Make sure to call back in if you want to keep them.

What? Is this some sort of sales guy lesson I missed? When a customer expresses dissatisfaction and is thinking about leaving, you shove them out the door?

The thing that most frightened me about this was that we have a lot of data in Salesforce – data I hope to migrate to the new system. While nothing in his correspondence stated it, words like “delete” jumped out, and it dawned on me that Salesforce could decide to nuke that data at any time and we would have little real recourse. Instead of helping the issue, Arunan not only insured that I would not be a customer of Salesforce come July, he instilled fear in me about a whole industry. If Salesforce decided, on a whim, to cut us off, we may have some legal recourse but in the meantime we would be screwed. Salesforce is a lot bigger than us and could probably keep us tied up for years. All just because a mediocre Account Manager wanted us off his list.

And think about it – before this exchange I would actually recommend Salesforce. Sure it was a little reserved, along the lines of “I am not super happy about them but they are the best alternative I’ve found” but it was a recommendation nonetheless.

I think it is possible to provide cloud based services in a secure fashion, but I am not sure Salesforce is one to do it. We are installing SugarCRM now, so I’ll post later with an update on how the migration went, and a more up to date understanding of Salesforce vs. Sugar.
