Technical bleg: curious iPad wifi problem

I bought my first iPad (original model) about six months after they came out, and replaced it with an iPad 2 about four months after they came out. So I’ve been using an iPad for about 2 1/2 years. For most of that period, my typical iPad usage has included checking e-mail and blogs first thing in the morning — while still in bed — and regular watching of streaming and downloaded content at night, again while in bed.

Then one evening about two weeks ago, as I went to watch something on Netflix, I noticed I had no wifi signal on my iPad, whereas I usually have a decent connection to my router (Netgear WNDR4500 dual-band). I brought up the Settings app and verified that WiFi was on. I went into the WiFi section; the name of the 5 GHz (we’ll call it “B2″) appeared, though with weak strength. (Note that the 2GHz band, “B1″, didn’t appear at all.) I tried to connect and got the “Could not connect to B2″ message. I walked out of our bedroom into the living room — the router is one floor up, in an open area — and immediately made the connection. Walked back into the bedroom towards my side of the bed and lost the signal again just as I was rounding the bed to the far side (where I sleep).

Repeat and rinse, with the usual thumps and reboots (rebooted router, rebooted iPad, moved router a bit, etc.), but continued to have the same problem. This is puzzling, because everything worked just fine up until then. Even more puzzling: my iPhone 4S, in exactly the same location, was connecting just fine to the router via the B1 band (which my iPad couldn’t even see). Likewise, the AppleTV in our bedroom — actually slightly farther away from the router and only about 6′ from where I sit on my bed — had a strong connection.

But here’s the most telling fact: if I use my wife’s iPad 2 — same model, same configuration (64GB/3G/wifi) — in the exact same spot on my side of the bed, I see strong signals from both B1 and B2 (vs. no B1 and an unconnectable B2 with my iPad).

My first solution was to go into the furnace room, where I have a wall of plastic storage drawers filled with various cables and components. I didn’t have a true repeater, but I fashioned one out a wireless bridge and an access point (i.e,. router <~> bridge <-> access point <~> iPad). It worked, but I still had one or two incidents of the iPad having trouble connecting to the access point, even though it was only 1-2′ away.

In the meantime, I did order a real repeater (Netgear dual band). When it arrived, I set it up in our bedroom about 10′ from where I would normally sit in my bed. It worked the first time I tried, but later that same day (yesterday), the iPad suddenly couldn’t see either SSID from the repeater, though it could see (as before) one of the router’s SSIDs (but would not connect to it). I moved the repeater closer — to the wall opposite the food of our bed — and suddenly I could see both of the repeater’s SSIDs.

So, somehow my iPad’s wifi capability has been diminished. I don’t know if it’s a hardware problem or a software problem. I may back it up and then do a clean restore. Anyone out there know of similar problems?

 

Weighing in on Project Orca

[Cross posted from And Still I Persist]

[Note: I am currently in transit from Colorado to Florida and am composing this post as I have time and 'net access.]

“All the most important mistakes are made on the first day.”

- The Art of Systems Architecting (Maier & Rechtin)

Project Orca was the Romney campaign’s technological effort to track in near-real-time actual voting in precincts all over the United States, with the intent of using that information in combination with individual-specific demographic databases to increase or pull back phone-call and door-knock get-out-the-vote (GOTV) efforts based on what was happening there. Since it appears more and more that Romney lost largely because of a lack of Republican turnout, it’s safe to say that the Romney/RNC GOTV effort was a failure. What is less clear is how much of an impact Orca had on that failure.

Three important disclosures up front. First, I was a Project Orca volunteer in Colorado. Second, I have no direct knowledge of how Orca was envisioned, developed, and operated beyond my own experience as an end user. Third, I’ve worked in software engineering and information technology since 1974, and my major professional focus since 1994 or so has been on how and why IT projects fail or succeed — a subject on which I’ve taught seminars, published books and articles, consulted in large corporations, and testified in courts and before Congress.

That said, the flap over Orca has made it all the way to the Drudge Report, largely due to two key discussions. The first is by JohnE over at Ace of Spades, who wrote the initial scathing report on Orca and followed it up with a reply to some of the push-back from the Romney campaign. The second is by Joel Pollack over at Breitbart, who had a Romney worker in Colorado who spoke of some of the problems.

My own experience matches much of what JohnE (who was also in Colorado) stated. I participated in four training calls. The first three all gave the same information about how the system would work, though — as JohnE noted — the Romney people kept refering to the Orca software as an “app”, even though it was simply a website that you logged into. (From JohnE’s comments, it sounds as though the use of the term “app” confused at least some Orca volunteers.)

Unlike JohnE, I was very clear from both the calls and the e-mails I receive that I needed to pick up my poll watcher certification and bring it with me to my assigned polling place on Election Day, so I am curious about his confusion. On the other hand, for my particular county (Douglas County), it appears that the certifications weren’t ready until the day before Election Day, which strikes me as cutting it a bit close. But I did drive down to Castle Rock on Monday afternoon and picked it up.

There was one more call the night before Election Day, but that was just a very brief, rah-rah call. After that Monday night call, I tried logging into the Orca web site to test out my password, but the log-in failed. I found that puzzling, but just assumed that they had the system locked down ether for security or administrative purposes.

Since Colorado is one of the few states that does not allow any electronic devices (phones, tablets, laptops) in polling places, I was also very clear from the training that I would have to print out the list of registered voters, bring it with me, mark off voters as they identified themselves at the polling place, and then periodically run out to my car and enter voting information via my iPad or iPhone. I printed out the list — and immediately discovered what I considered the first, admittedly minor, glitch: the list, a PDF file over 60 pages long, was formatted in such a way that you could not three-hole-punch the sheets (to put in a binder) without punching through the check boxes (for tracking voting and reporting) for some of the voters on each page. As I said, minor, but my technical writing background made me frown a bit. Since I own Adobe Acrobat, I solved the problem via the kludge of adding headers and footers to each page and then telling the pages to shrink themselves to fit.

So, with two binders in hand (I printed two copies of the list), with iPhone, my iPad, and my laptop in the car — along with two Black & Decker power boxes, and a couple of folding camp chairs — I showed up at my polling place at 6:45 am. I also brought with me three dozen fresh donuts (a suggestion from one of the training calls) that were greatly welcomed and did much to smooth relations with the actual poll workers.

Everything went well until the first time I went out to the car to report voters. I tried to log into the Orca website, and once again I got a “login failed” error message. (Second minor but telling item: that error message had a typo in it. The fact that such a typo was in a high-probability error message in a live system with over 30,000 anticipated users speaks to haste and sloppiness.) I called the help number given in the error message, and got a support person at the Boston command center who said they would reset my password and gave me the new code, but that it would take a little while for the new code to go live.

When I came back out again an hour or so later and tried to log in, the new password didn’t work either. The Orca system also had a call-in option, so I tried that and was told that my PIN was invalid.

At this point, it was about 8:30 in the morning. The next eight or so hours were all more of the same — I would call, the password would be reset, I would wait a while, I would try to log in, it would fail. Rinse and repeat. I was told by some of the support people I spoke with that almost no one in Colorado was able to log in — a geographical uniqueness that I found puzzling, since the login screen just asked for username (an e-mail address) and password. Another support person mentioned that there were similar problems being reported for North Carolina. Finally, sometime around 4:30 to 5:00 pm, I was given a new pin for the dial-in line — and that finally worked. I reported all the voters who had voted so far that day and did updated reports twice more before the poll finally closed at 7:00 pm.

JohnE pushes back (with justifiable skepticism) against Zac Moffat’s claims that “the campaign had voting data from 91 percent of counties” — not that they is necessarily inaccurate, but that it could be largely irrelevant. As JohnE points out, there can be hundreds of precincts in a single county; beyond that, having voting data from a given county does not necessarily mean having actionable, timely, and sufficiently complete data throughout the day in order to make GOTV decisions for that county (or for a given precinct in that county).

There is still no evidence that there were significant Orca problems outside of Colorado; we’ll have to wait to see if someone on the inside of Orca development decides to leak. But here are some observations from an large-scale IT system development perspective.

“A complex system that works is invariably found to have evolved from a simple system that works. . . . A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over, beginning with a working simple system.”

Systemantics (John Gall)

First, the Orca folks basically released version 1.0 (or, perhaps more accurately, version 0.9 or lower) into a massive, live environment on the single most critical day, Election Day. This is commonly known in IT circles as the “Big Bang” approach, and it is a well-known harbinger of disaster. Even if the Orca developers were all geniuses, this still would be a grave error. We’re not talking about an iOS or Android app being used by a single person on his/her device for entertainment or productivity; we’re talking about a massive web-based system that has to accept data from (not just deliver content to) possibly tens of thousands of users simultaneously and in real time. There should have been days, if not weeks, of live tests and trials to see how the system performed and to get the kinks worked out. Instead, as far as I can tell, the first time most Orca volunteers actually used (or tried to use) the system was on Election Day. Even if the system worked perfectly, I doubt that the majority of users — who had no real training on the system — would have used it in an effective manner.

“There are products that you shouldn’t develop, companies you shouldn’t challenge, customers you shouldn’t win, markets you shouldn’t enter, recommendations from the board of directors you shouldn’t follow.”

The Art of ‘Ware (Webster)

Beyond that — and as per the quote above (paraphrasing Sun Tzu), as well as the one at the start of this post — the real question is: should this have been attempted in the first place? There are anecdotal reports that the focus on Orca took away resources — especially feet-on-the-ground resources — for local GOTV efforts. And GOTV is exactly where the Republicans failed. If work on Orca had been started 3 or 4 years ago, and if it had been used on Election Day 2010 — both as a real-world test and to verify the expected benefits of matching actual voters with demographic information to predict results in a given precinct — then it might have been ready for prime time on Election Day 2012.

But to spend signficant time, money, and resources (including tying up some 30,000+ local volunteers) for an untested system and an untried concept was a recipe for disaster — a well-known recipe, I might add, for those of us who have studied large-scale IT projects (which, frankly, are prone to failure anyway).

“But,” you ask, “you signed up to volunteer.” Yes, I did. But I had no visibility into the project and no inherent reason in advance to assume that things weren’t being done well, beyond the few niggling questions I had prior to Election Day. And, to be perfectly fair, I have no evidence of the extent of problems beyond Colorado, aside from the acknowledged 90-minute downtime on Election Day morning. But, even if those are the only two failures, can you seriously argue that it was a success? A time-critical, mission-critical system whose entire purpose for existence is to be used in a single 12-hour window is down for over 10% of that time in all states and is down all day in one critical swing state?

And, finally, the bottom line: if the purpose of Orca was to provide real-time intelligence on actual voting trends and make GOTV more effective, then where are the results? By all accounts, the Romney campaigned was stunned by their loss; if Orca was providing accurate, real-time indication of voting, as the project directors claimed it would in the training calls (actual quote [from memory]: “We’ll know ahead of anyone else how the election is turning out.”), then Romney should have had his concession speech written well in advance. And if its goal was to trigger targeted GOTV efforts in swing states, then why did Romney lose almost every swing state? Measured by its stated goals, Orca was a failure, pure and simple. Worse yet, it may have diverted critical resources from more effective GOTV efforts.

“Start out stupid and work up from there.”
– Bruce Henderson

I’d love to be able to do a project post mortem on Orca, as I have done on so many troubled, failing, or failed projects. But even without access to people and documents, I can hazard a guess at some of the likely factors:

  • A late start and an impossibly short schedule.
  • Because of these above, a waterfall (single pass) approach to design, development and deployment, instead of an iterative approach.
  • Lack of a single chief software architect, with resulting problems at subsystem interfaces.
  • A large development team with no prior track record developing and releasing software as a single team.
  • Along the same lines, key components divided up among separate teams with relatively late integration and testing.
  • And possibly some turnover (departure) of key personnel through the project, along with new personnel added late.
  • Insufficient resources (money, personnel, equipment, time) devoted to quality assurance — and by “quality assurance”, I mean not just a wide range of testing (including, as JohnE points out, stress testing), but also individuals and teams with proper expertise, agreed-upon standards and guidelines, reviews, metrics, defect management, and so on.
  • A firm belief — without any real-world evidence — that the idea would actually work and that the results would actually be worth the diversion of resources (including volunteers).

I’m happy to talk with anyone from the project who wants to set me straight or explain what really happened. But, in the end, what really happened was that Orca failed to achieve its goals, and Romney lost what should have been a very winnable election. ..bruce w..

A must-read for all software engineers and their managers

Thanks to Cat Mikkelsen [yes, ex-NeXT people, that Cat], I read this article. It’s written by Linds Redding, an art director and animator down in New Zealand who just passed away a few days ago. But it is very, very relevant to software engineering, particularly the ‘heroic’ model of software development. In it, he talks about the brainstorming he and his colleagues used to do, and then the fact that they would all go home, let the ideas sit overnight, and then reconsider them the next day “in the cold light of morning”. He then talks about how digital tools and deployment have steadily shortened that time of reflection from overnight to over lunch to the next ten minutes. An excerpt:

…I think I’ve come to the conclusion that the whole thing was a bit of a con. A scam. An elaborate hoax.

The scam works like this:

1. The creative industry operates largely by holding ‘creative’ people ransom to their own self-image, precarious sense of self-worth, and fragile – if occasionally out of control ego. We tend to set ourselves impossibly high standards, and are invariably our own toughest critics. Satisfying our own lofty demands is usually a lot harder than appeasing any client, who in my experience tend to have disappointingly low expectations. Most artists and designers I know would rather work all night than turn in a sub-standard job. It is a universal truth that all artists think they a frauds and charlatans, and live in constant fear of being exposed. We believe by working harder than anyone else we can evaded detection. The bean-counters rumbled this centuries ago and have been profitably exploiting this weakness ever since. You don’t have to drive creative folk like most workers. They drive themselves. Just wind ‘em up and let ‘em go.

2. Truly creative people tend not to be motivated by money. That’s why so few of us have any. The riches we crave are acknowledgment and appreciation of the ideas that we have and the things that we make. A simple but sincere “That’s quite good.” from someone who’s opinion we respect (usually a fellow artisan) is worth infinitely more than any pay-rise or bonus. Again, our industry masters cleverly exploit this insecurity and vanity by offering glamorous but worthless trinkets and elaborately staged award schemes to keep the artists focused and motivated. Like so many demented magpies we flock around the shiny things and would peck each others eyes out to have more than anyone else. Handing out the odd gold statuette is a whole lot cheaper than dishing out stock certificates or board seats.

3. The compulsion to create is unstoppable. It’s a need that has to be filled. I’ve barely ‘worked’ in any meaningful way for half a year, but every day I find myself driven to ‘make’ something. Take photographs. Draw. Write. Make bad music. It’s just an itch than needs to be scratched. Apart from the occasional severed ear or descent into fecal-eating dementia the creative impulse is mostly little more than a quaint eccentricity. But introduce this mostly benign neurosis into a commercial context.. well that way, my friends lies misery and madness.

This hybridisation of the arts and business is nothing new of course – it’s been going on for centuries – but they have always been uncomfortable bed-fellows. But even artists have to eat, and the fuel of commerce and industry is innovation and novelty. Hey! Let’s trade. “Will work for food!” as the street-beggars sign says.

This Faustian pact has been the undoing of many great artists, many more journeymen and more than a few of my good friends. Add to this volatile mixture the powerful accelerant of emerging digital technology and all hell breaks loose….

I read this and I think of all the app development shops and startups that are trying to create the next Angry Birds, and the people working therein. Thoughts?  ..bruce..

 

Capital One locks out Quicken — but for how long? [UPDATED: not for long]

[UPDATE 11/08/12: Sometime in the past few weeks, the problem went away. I assume Capital One and/or Quicken came to whatever decisions they needed in order to allow automatic downloads once again.]

I have a few Capital One credit cards — have had them for years. I use Quicken to track my finances and have it set up to download financial transactions automatically once a day from all my financial accounts, including Capital One.

A week or so ago, I started getting error messages from Quicken stating that it was unable to download my Capital One transactions. I get these occasionally — say, once every week or two — for different accounts, so I didn’t think too much of it.

But then the error messages were there again the next morning. And when I tried a manual download of Capital One transactions, I got the same message. I kept getting error messages each day. The Quicken messages at first suggested that I needed to log into my accounts at Capital One and authorize downloading of transactions. I logged in…and could find no such authorization. Then the error message within Quicken changed to read, “We couldn’t complete the downloads for your account(s) because your financial institution has disallowed access.”

Hmm.

So a day or two ago, I logged onto the CapOne web site and sent the following message:

I use Quicken to track my expenses. For the last week or so, CapOne has refused to let Quicken download my transactions. Why? (this applies to all my C1 cards)

To which I received this response:

Thanks for your message.

We regret any inconvenience you may have experienced.

Please know that Capital One® does not support Direct Connect services which allow customers to directly load their statements into their financial software.

Thanks for being a Capital One customer.

Regards,

Capital One

Huh? My re-response:

Well, you did up until a few days ago. I’ve had Quicken automatically downloading my credit card statements daily for months. Why the (unannounced) change in policy? And why should I stay with CapOne (vs. balance transfer to other banks that continue to allow downloads)?

To which I received this wonderfully informative and helpful response:

Thanks for your message.

We’ll be glad to assist you. Please call our Online Technical Support Department at 1-866-750-0873 and say or choose the corresponding option number from the following choices:

Unlock Account or press 1
Reset Password or press 2
Mobile Banking or press 3
Technical Support or press 4
General Account Questions or press 5

Our representatives are available 24 hours every day for your convenience.

Thanks for being a Capital One® customer, and please let us know if there’s anything we can do for you in the future.

Regards,

Capital One

So, there you have it. With no prior announcement or warning, Capital One has apparently suddenly disallowed downloading transactions directly into financial software.

Note that I did do some searching online and found a discussion of similar problem from a year ago. It suggested that the problem might be with Quicken and gave a solution.  Tried it. Didn’t work. On the other hand, the Capital One website still gives instructions as to how to download transactions into Quicken. On the gripping hand, this discussion over at Intuit tech support indicates that it’s due to a server/DDOS problem at CapOne, and it’s unclear how long it will take to resolve it, if ever.

I’m curious if others have noticed this problem.  ..bruce w..

 

iPad Mini: the Goldilocks iPad for kids

With the growing swell of articles about the still-hypothetical iPad Mini — see, for example, this thoughtful analysis over at Vodkapundit – I find it interesting that I see very little written about one of the hottest consumer niches for the iPad: kids. Which is surprising, since kids desperately want to get their hands on iPads.

My sweet wife and I have 14 grandkids (a consequence of having jointly raised 9 kids in a combined family). When we go to visit them or they come to visit us, here’s pretty much how it goes:

Grandchildren: “Grandma! Grandpa!”

Hugs all around.

Each grandchild over the age of 4 or so, within 60 seconds and sometimes a good deal less: “Can I play with your iPad?” or “Well, can I play with your iPhone, then?”

And that’s the last we see of our iPads (and, depending upon how many grandkids are around, our iPhones) for the next several hours.

The iPhone (or iPod Touch) is definitely a consolation prize in this race: much smaller screen and a bit harder for the kids to manipulate. On the other hand, iPads are larger, heavier, more difficult to hold, more fragile, and more expensive.

But an iPad mini would be just right for kids. The right size and weight, and the right price point. It will easily slip into a backpack. And it will have all the iPad functionality.

So if in fact Apple does announce and release the iPad mini later this month — how many iPad minis will be under Christmas trees or wrapped as Hanukkah gifts in December?

Millions, I’d wager. Millions. ..bruce..

P.S. And that doesn’t even begin to touch the K-8 educational market.
