There seems to be some backlash going on against the religion of “Agile Software Development” and it is best summarized by PragDave, reminding us that the “Agile Manifesto” first places “Individuals and interactions over processes and tools” — there are now a lot of Agile Processes and Tools which you can buy in to . . .
He then summarizes how to work agilely:
What to do:
Find out where you are
Take a small step towards your goal
Adjust your understanding based on what you learned
How to do it:
When faced with two or more alternatives that deliver roughly the same value, take the path that makes future change easier.
Sounds like sensible advice. I think I’ll print that out and tape it on my display to help me keep focused.
I had the worst experience at work today: I had to prepare a computer for a new employee. That’s usually a pretty painless procedure, but this user was to be on Windows, and I had to … well, I had to call it quits after making only mediocre progress. This evening I checked online to make sure I’m not insane. A lot of people hate Windows 8, so I enjoyed clicking through a few reviews online, and then I just had to respond to Badger25’s review of Windows 8.1:
I think you are being way too easy on Windows 8.1 here, or at least insulting to the past. This isn’t a huge step backwards to the pre-Windows era: in DOS you could get things done! This is, if anything, a “Great Leap Forward” in which anything that smells of traditional ways of doing things has been purged in order to strengthen the purity of a failed ideology.
As far as boot speed, I was used to Windows XP booting in under five seconds. That was probably the first incarnation of Windows I enjoyed using. I just started setting up a Windows 8 workstation today for a business user and it is the most infuriatingly obtuse Operating System I have ever, in decades, had to deal with. (I am a Unix admin, so I’ve seen things….) This thing does NOT boot fast, or at least it does not reboot fast, because of all the updates which must be slowly applied.
Oddly enough, it seems that these days, the best computer UIs are offered by Linux distros, and they have weird gaps in usability, then Macs, then … I wouldn’t suggest Windows 8 on anyone except possibly those with physical or mental disabilities. Anyone who is used to DOING THINGS with computers is going to feel like they are using the computer with their head wrapped in a hefty bag. The thing could trigger panic attacks.
Monday is another day. I just hope the new employee doesn’t rage quit.
I think the El Camino BRT could be a great project to transform El Camino Real from a ghetto of 1950s strip malls into the sort of place where people would go to enjoy shopping. Maybe. Anyway, the news that a dedicated lane from Santa Clara to Palo Alto could make the bus faster than cars excited me. I’ll try to be at the Sunnyvale meeting this evening, and I also submitted my own enthusiasm to our governments via Transform’s handy link:
I used to commute along El Camino from Mountain View to Palo Alto. I switched to the bus out of environmental concerns. El Camino has the best transit service in the county but it still took 2-3 times longer to take the bus than it would have taken to drive. Now it sounds like you could get BRT running on El Camino FASTER than cars? YES!! If the cars get slowed a bit that’s not such a big deal, especially since any driver going any distance knows that Central Expressway / Alma is a much nicer car trip. Even though I now live 1.5 miles off of El Camino in Sunnyvale, if there were excellent transit services I would be tempted to hop on the 55, walk, or bike to enjoy the transit corridor, especially for trips up to Mountain View or Palo Alto or Stanford Shopping Center. What a pleasure it would be to not have to hassle with parking, traffic, or the Caltrain schedule. If it were sufficiently fast, I would totally use that as a commute option up to Menlo Park.
Also, I’d probably be more inclined to visit Santa Clara.
We had company over Wednesday evening. Friends of the family who have cat-sat for us. They brought dim sum. After dinner we sat around chatting. I got a call on my mobile from a 408 number. I took it.
“Are you the owner of Maxwell?”
“I am. Is he causing trouble?”
It was the opposite. I grabbed a cardboard box and hustled down to the corner, where a small crowd had gathered. The woman who had called me said he had been standing in the street, looking the other way, when the car hit him. He died instantly. She removed him from the street and found my number on the tag. We hugged. She was obviously a cat person, who was glad that he had a collar, a bell, and an identification tag.
I brought him home. He rested briefly where his feline companion Maggie took a last opportunity to groom him. The young woman who drove the car and her father came by to express their remorse and see if they could make amends, but there was nothing to be done. The young woman was in tears. She wants to be a veterinarian. The Father remembers dogs who had been lost to cars. We agreed that the Humane Society might receive a donation. We shook hands several times. What a way to meet the neighbors.
Maxwell napping in the front yard in June.
In the back yard, a shallow grave was dug. Maxwell was wrapped in a familiar fabric, and lain to rest. Words were said.
It will take some time to feel his absence and truly mourn his departure. He might have lived a much longer life as a house cat, but he loved the outdoors and was well known in the neighborhood. He lived as he chose and while his end was violent, it was swift and he did not suffer.
At work, I have a Thunderbolt display, which is a very comfortable screen to work at. When I leave my desk, the VMWare guest transfers to the Retina display on my Mac. That is where the trouble starts. You can have VMWare give it less resolution or full Retina resolution, but in either case, the screen size changes and I have to move my windows around.
1) In the guest OS, set the display size to: 2560×1440 (or whatever works for your favorite external screen …)
I reported the following to the FBI, to LogMeIn123.com, to Century Link, and to Bing, and now I’ll share the story with you.
Yesterday, May 12, 2014, a relative was having trouble with Netflix. So she went to Bing and did a search for her ISP’s technical support:
Bing leads you to a convenient toll-free number to call for technical support!
She called the number: 844-835-7605 and spoke with a guy who had her go to LogMeIn123.com so he could fix her computer. He opened up something that revealed to her the presence of “foreign IP addresses” and then showed her the Wikipedia page for the Zeus Trojan Horse. He explained that she would need to refresh her IP address and that their Microsoft Certified Network Security whatevers could do it for $350 and they could take a personal check since her computer was infected and they couldn’t do a transaction online.
So, she conferenced me in. I said that she could just reinstall Windows, but he said no, as long as the IP was infected it would need to be refreshed. I said, well, what if we just destroyed the computer. No, no, the IP is infected. “An IP address is a number: how can it get infected?” I then explained that I was a network administrator . . . he said he would check with his manager. That was the last we heard from him.
I advised her that this sounded very very very much like a phishing scam and that she should call the telephone number on the bill from her ISP. She did that and they were very interested in her experience.
I was initially very worried that she had a virus that managed to fool her into calling a different number for her ISP. I followed up the next day, using similar software to VNC into her computer. I checked the browser history and found that the telephone number was right there in Bing for all the world to see. She doesn’t have a computer virus after all! (I’ll take a cloer look tonight . . .)
I submitted a report to the FBI, LogMeIn123.com, Bing, and Century Link. And now I share the story here. Its a phishing scam that doesn’t even require an actual computer virus to work!
As a SysAdmin, people ask me how much they need to worry over the heartbleed vulnerability. Here’s my own take:
Google were known to be vulnerable. They co-discovered the vulnerability and deployed fixes quickly. I like to believe they are analyzing the scope and likelihood of user password compromise and will issue good advice on whether Gmail passwords should be updated.
For everything else, my small opinion is “don’t panic.” Not every web site would have been affected. The Ops folks at each site need to patch their systems and assess the extent to which credentials may have been compromised, then take appropriate steps to mitigate compromised data, which might include asking users to set new passwords. But if they’re still waiting on some patches, then submitting a new password could actually put both passwords at risk.
For other important passwords, like your bank, check up on what they’re recommending that you do. If a site is important to you and they offer two-factor auth, go for it: that typically means that if you log on from a new computer they’ll text a one-time pin code to your mobile phone to double-check that it’s you.
How do you triumph against an oppressor who has an overwhelming advantage in terms of firepower? If you are Mahatma Gandi, Martin Luther King Jr, Nelson Mandela, or Ukrainian Colonel Yuri Mamchur, you practice non-violent direct action. I hope that Ukraine may yet share in the triumph of this strategy.
Marching along with the Ukraine brigade were the wives of four of the officers, all standing surrounded by Russian snipers at Belbek
Phone battery dying. Read @Time a bit later for the hair-raising conclusion of the ballsiest move of the Crimean conflict so far. #Belbek
I first read of the story via ABC News. I think this is an excellent strategy to employ against the Russian occupation. Putin claims the Russians are there to defend against violent acts. It would appear that the Ukrainian Military are Not the Problem here. I hope this tactic is employed further by Ukraine’s soldiers and its people, and I wish to see them succeed. Mamchur and his soldiers are heros of humanity.
I started trying to use Fitbit to track calorie consumption again the other day. This gets frustrating pretty fast because unless you only eat processed food from packages of specific size you mostly have to accept that calorie counting is a wildly inaccurate guessing game.
I’m happy to embrace the mystery and accept approximate measurements for the most part, but I figured there was one thing I could tackle: breakfast! The most important meal of the day … and I tend to eat the same thing: a bowl of Trader Joe’s Raisin Bran with skim milk. (Trader Joe’s is the only raisin bran I can find any more where the raisins aren’t coated in sugar.)
In theory, this is trivial to figure out. The information is posted right on the side of the box:
So, how many calories am I eating, here?
Caveat: I eat cereal by the bowl, not by the cup! I also eat with some quantity of skim milk.
I whipped out my trusty digtal kitchen scale:
1) Switch scale back to metric
2) Place bowl on scale
4) Pour a bowl of cereal, note weight (129g)
6) Pour milk, note weight (331g)
7) Remove bowl from scale and enjoy breakfast before everything goes soggy
Cereal calories are easy to figure: 129/55 * 170 = 399 calories
Milk servings are measured in ml, though. The moment I started trying to look up the volume of a gram of milk, Google just gave me the answer: 113 calories
Two quotes passed along on September 11, from my meat-eating Grandmother:
A USDA inspector reviews the carcasses of slaughtered pigs for our safety. Credit: Wikmedia Commons
“As long as there are slaughterhouses there will be battlefields.” –Leo Tolstoy
“We are the living graves of murdered beasts
slaughtered to satisfy our appetites.
We never pause to wonder at our feasts,
if animals, like men, can possibly have rights.
We pray on Sundays that we may have light,
to guide our footsteps on the path we tread.
We’re sick of war, we do not want to fight –
The thought of it now fills our hearts with dread,
and yet – we gorge ourselves upon the dead.
Like carrion crows we live and feed on meat,
regardless of the suffering and pain
we cause by doing so, if thus we treat
defenseless animals for sport or gain
how can we hope in this world to attain
the PEACE we say we are so anxious for.
We pray for it o’er hecatombs of slain,
to God, while outraging the moral law,
thus cruelty begets its offspring – WAR.”
–George Bernard Shaw

We were somewhere around Barstow on the edge of the desert when the drugs began to take hold. I remember saying something like “I feel a bit lightheaded; maybe you should drive….” And suddenly there was a terrible roar all around us and the sky was full of what looked like huge bats, all swooping and screeching and diving around the car, which was going about a hundred miles an hour with the top down to Las Vegas. And a voice was screaming “Holy Jesus! What are these goddamn animals?”
Then it was quiet again. My attorney had taken his shirt off and was pouring beer on his chest, to facilitate the tanning process. “What the hell are you yelling about?” he muttered, staring up at the sun with his eyes closed and covered with wraparound Spanish sunglasses. “Never mind,” I said. “It’s your turn to drive.” I hit the brakes and aimed the Great Red Shark toward the shoulder of the highway. No point mentioning those bats, I thought. The poor bastard will see them soon enough.

I added the quotation marks manually, as well as the paragraph break. My phone, unlike others, does not seem to understand the “new paragraph” command. The original text, was stolen from http://www.galleries.com/jeff/gonzo.htm, which was stolen from Hunter S. Thompson, who is dead.
At long last, I retired my old T-Mobile G2. It was the last in a long line of phones I have owned for the past decade with a physical keyboard. (I think I owned every Sidekick up to the 3 before going Android with the G1 and the G2.) I like the ability to thumb type into my phone, but the G2’s old keyboard had long ago gone creaky, and it had lacked a dedicated number row besides.
Obligatory picture recently taken with my new computer telephone. Featuring a cat.
They don’t make nice smart phones with keyboards any more. Market research seems to indicate that the only remaining markets for keyboard phones are horny teenagers who need a cheap, hip Android-based Sidekick, and those legions of high powered business people who will never abandon their ancient Blackberries.
Anyway, the new Nexus 5 is here. The on-screen keyboard is okay slow and inaccurate. Like moving from a really fantastic sports car to a hovercraft piloted by a drunken monkey. I mean,the monkey-piloted hovercraft is undeniably cool technology, and I can eventually get where I need to go, but . . . its not the same, you see?
So, lets explore Voice dictation! It works . . . well, about as well as the monkey hovercraft, but with the added benefit that you don’t have to keep jiggling your thumb across the screen. But how do you do new lines and paragraphs? Where’s the command reference?
The other thing that excited me about the Nexus 5 was that on the home screen you can drag apps right up to “Uninstall” . . . unless they’re Google apps! “Way to not be evil,” I cried. Until a Google colleague pointed out that it was just a bit of UI funkiness on Google’s part, owing to the applications coming bolted into the UI, there is at least a method to disable them.
Anyway, this is useful knowledge that helped me to vanquish the Picasa sync thing that has been hiding images from the gallery for the past few years. I have another project where I’m testing out BitTorrent Sync to pull images off our phones and then sync a copy of the family photo archive back down to the phones. If that works out, I’ll write it up. I may pursue that further to see if I can’t replace Dropbox, which, unfortunately, does not (yet) offer any sort of a family plan. Also, if I can host my own data I needn’t share as much of it with the NSA.
Two weeks ago, I attended Atlassian Summit 2013 in San Francisco. This is an opportunity to train, network, and absorb propaganda about Atlassian products (JIRA, Greenhopper, Confluence, &c.) and ecosystem partners. I thought I would share a summary of some of the notes I took along the way, for anyone who might find interest:
At the Keynote, Atlassian launched some interesting products:
As time passes, the ticket gets crankier at you in real time about the SLA.
Jira Service Desk
Jira Service Desk is an extension to JIRA 6 oriented around IT needs. The interesting features include:
Customer Portal with integrated KB search
Real-time visibility of ticket SLA status
The first thing helps people get their work done, and the second is manager catnip.
Another feature for tight integration is Webhooks: you can configure JIRA so that certain issue actions trigger a hit to a remote URL. This is generally intended for building apps around JIRA. We might use this to implement Nagios ACKs.
I haven’t looked too deeply as this is a JIRA 6 feature, but Atlassian Connect promises to be a new method of building JIRA extensions that is lighter-weight than their traditional plugin method. (Plugins want you to set up Eclipse and build a Java Dev environment in your workstation… Connect sounds like just build something in your own technology stack around REST and Webhooks)
Cultivating Content: Designing Wiki Solutions that Scale
Rebecca Glassman, a tech writer at Opower, gave a really engaging talk that addresses a problem that seems commonplace: how to tame the wiki jungle! Her methodology went something like this:
Manage the wiki like it is a product: interview stakeholders, get some metrics, do UX testing
Metrics: Google Analytics, View Tracker Macro, Usage Macro
UX results at Opower revealed more reliance on Table of Contents vs Search (55%) and that users skip past top-level pages, so you don’t want to put content just on there
In search, users only look at the first 2-3 results before giving up
They engaged some users to track the questions they had and their success at getting answers from the wiki
The Docs people (2) built an “answer desk” situation where they took in Questions from across the company, and tracked their progress writing answers on a Kanban board
As they better learned user needs and what sort of knowledge there was, they built “The BOOK” (Body of Opower Knowledge) based on a National Parks model:
Most of the wiki is a vast wilderness, which you are free to explore
The BOOK is the nice, clean visitors center to help take care of most of your needs and help you prepare for your trek into the wilderness
The BOOK is a handbook, in its own space, with its own look-and-feel, and edits are welcome, but they are vetted by the Docs team via Ad Hoc Workflows
By having tracked Metrics from the get-go, they can quantify the utility of The BOOK …
(I have some more notes on how they built, launched, and promoted The BOOK. The problem they tackled sounds all to familiar and her approach is what I have always imagined as the sort of way to go.)
Ad Hoc Canvas
The Ad Hoc Canvas plugin for Confluence caught my eye. At first glance, it is like Trello, or Kanban, where you fill out little cards and drag them around to track things. But it has options to organize the information in different ways depending on the task at hand: wherever you are using a spreadsheet to track knowledge or work, Ad Hoc Canvas might be a much better solution. Just look at the videos and you get an idea . . .
The Dark Art of Performance Tuning
Adaptavist gave a presentation on performance analysis of JIRA and Confluence. It was fairly high-level but the gist of this is that you want to monitor and trend the state of the JVM: memory, heap, garbage collection, filehandles, database connections, &c. He had some cool graphs of stuff like garbage collection events versus latency that had helped them to analyze issues for clients. One consideration is that each plugin and each code revision to a plugin brings a bunch of new code into the pool with its own potential for issues. Ideally, you can set up a load testing environment for your staging system. Short of that, the more system metrics that you can track, you can upgrade plugins one at a time and watch for any effects. As an example, one plugin upgrade went from reserving 30 database connections to reserving 150 database connections, and that messed up performance because the rest of the system would become starved of available database connections. (So, they figured that out and increased that resource..)
tl;dr: JIRA Performance Tuning is a variation of managing other JVM Applications
Collaboration For Executives
I popped in on this session near the end, but the takeaway for anyone who wants to deliver effective presentations to upper management are:
