MacBook Air overheating with OS X Lion and FileVault

I noticed today that my Mid-2009 work-provied MacBook Air, which I recently freshly installed with Lion, was generating a ton of heat, and operating really slowly. I noticed that the kernel_task process was using between 130% and 150% CPU, and the CPU meter was completely full. Meanwhile, no other processes were using a significant amount of RAM and CPU (in fact, I have barely installed anything on this machine yet). I tried quitting all of my applications, unplugging all peripherals, and disabling wifi with no change. I rebooted with no change. Even researching the problem online was highly frustrating because things were going so slowly.

After reading a variety of message board postings I came to the conclusion that the kernel_task high CPU usage was a symptom, not a cause. The machine was overheating due to a combination of very high temperatures (high-90s F) and being seated on a surface that did not allow it to dissipate heat effectively. The kernel_task was running, apparently, to keep other processes from using the CPU.

Strange as this seemed, there was an easy test — I plopped the laptop, now running nothing else, in front of an air conditioner and hit it full blast. Within a few minutes the kernel_task process dropped to 70-80% CPU usage and things became responsive again. But even though the laptop was cool to the touch, the process never went down from there.

My next thought was that perhaps the new FileVault full-disk encryption was playing a role, since it was one of the only things running once I had disabled all third-party processes and quit all apps. So I set the hard drive to decrypting, which took only 20-30 minutes on SSD. Sure enough, as soon as it completed, the kernel_task processor usage dropped to almost nothing.

I’m not going to repeat the experiment to verify the results, so use this as one data point only. But if you are experiencing similar behavior, first cool the machine and move it to a hard, flat surface. That should alleviate most of the symptoms.

Geeking Out

Everyone’s a pundit

The rumors about upcoming iPhones and iPads are very straightforward this cycle compared to previous years, when lots of crazy ideas were always bandied about. Let me throw my hat in the ring and see how well I do at crystal ball prognostication, since the stakes are so low!

iPad

There are currently 18 (yes 18!) different models of iPad. This is unsustainable and causing inventory problems. At the same time, demand is so high and the iPad 2 so new that there is unlikely to be a major change in specs this holiday season.

I predict instead that Apple will streamline its models and simplify the iPad line in three ways. First, I predict that the 16GB model will be discontinued, and the 32GB model lowered in price to $499. Second, if the long-rumored “retina” high resolution iPad displays are ready to go, the 64GB model will keep its same price point but be updated with the better display. (If it isn’t ready, that model will simply receive a $100 price reduction). Third, the 3G models will switch to a new combined radio that allows them to work on either Verizon or AT&T (and possibly other carriers) without having to purchase carrier-specific models. These changes will decrease the number of models from 18 to 8 (32 and 64 GB, wifi and 3G, black and white), and hopefully relieve inventory problems.

iPhone

A new iPhone 5 (or iPhone 4S, although I predict “5” to match up with the new iOS 5) is certain. It will probably contain only minor feature improvements, such as a higher resolution rear-facing camera or longer battery life, since the iPhone 4 last year introduced a major design refresh. The wildcard is what will happen on the “low-end”, where the iPod touch and iPhone may start converging more. I wonder if the time has come for a 3G iPod touch similar to the iPad, or a lower-end iPhone that is “pay as you go”. I suspect that either way the traditional hard-drive based iPod will finally be discontinued.

First world gripes, this time about Peapod

Hull is not entirely convenient to the supermarket, so a couple nights ago I tried using Peapod again. The service lets you shop online and they deliver to your door, using an excessive number of plastic bags and, in my experience, always coming at least a half hour after their scheduled delivery window. Using Peapod isn’t really that much quicker than going to a store, but it allows one to avoid lines and reuse old shopping lists, so it does have some advantages.

In this particular instance I missed the early boat due to some work stuff being broken and got home 30 minutes into my two hour deliver window. The story ends as you might expect — while I fumed at them for being so late, in reality they had come right at the beginning of the window, I wasn’t home, and they drove off with my groceries. The consequences are no groceries and a hefty $50 restocking fee. And now I have to go to the grocery store anyway.

This seems like a common enough problem that there should be ways to mitigate it. When I was using the excellent Boston Organics while living in Cambridge, they made their deliveries in re-usable green plastic tubs and would place them at a location specified by the homeowner if no one was there to receive them. They also encouraged the use of supplementary coolers and/or ice packs. The delivery driver would redistribute the most perishable or fragile items to a cooler if one was provided. This approach is environmentally friendly, convenient, and much more forgiving in terms of time delays — on both sides.

Peapod’s method of leaving the customer in the dark with no email or web communication and their inability to deliver when someone is not home makes the service much less desirable than Boston Organics. Their use of copious numbers of plastic bags makes them much less environmentally friendly. It is exacerbated by the fact that the plastic bags are then placed into plastic bins, but the bins are not a part of the delivery.

I share some of the blame in this instance, for getting home late, but a good customer-focused company, especially a delivery company that traffics in perishable goods like Peapod, should have very robust exception handling to deal with such situations. I discovered this morning that they left one message on my home phone, whereas I was looking for a call on my cell or an email or text message. There is lots of room for improvement here.

And it may go without saying, but Peapod has proven to be less convenient to me than just going to the grocery store, so I do not plan to use their service in the future.

I miss the radio dedication show. People would phone in, and dedicate songs to one another. This only worked because of serendipity: the voice on the radio would catch your attention by calling you by name like someone in the next room. They’d then say the name of someone that you knew, then play a dedicated song from them. It was a thoughtful gift traveling through waves in the air. The whole thing works under the presumption that you would be listening. Dedications don’t work if we don’t regularly congregate in the same place, so there is a part of me that fears it may be gone forever. What made the whole thing great was a special presence of a felt, but invisible connection. There was a thoughtfulness in the choice of the song, but also in the communal aspect of knowing that everyone else listening to the radio was hearing your song as well. And then it was gone. Vanished, evaporated, and you’re left with that warm feeling when something good passes.

The enthusiasm gap

I went into the home inspection nervous about what we would find. The house was lacking in all possible “curb appeal,” which brought down the price to what we could afford, but was it structurally sound? The home inspector, an old guy nearing retirement, was almost universally positive. I pointed out areas of concern — plumbing? Fine. What about the siding, which looks terrible? That stuff lasts forever. Boiler? Practically new! (It is about 20 years old.) And the roof? Seems to be in good shape! This is a great house, he kept saying, you’re going to do well here.

Pleasantly surprised (and a bit confused), we addressed a few small inspection issues with the seller and obtained a closing credit towards some future repairs, and moved forward with the purchase.

It needs some work

After moving in we called in a respected contractor in the area that specializes in restoring old homes. The team of two brothers took us through the entire house, jumping on floors, poking and prodding, making lots of notes. They asked us what we wanted and what our ideas were, and took a copy of the inspection report. They came back with a proposal that was slightly jaw-dropping in price, but comprehensive. They found old knob-and-tube wiring which needed to be replaced, recommended upgrading to 200 amp service, pointed out problems with floor joists and old plumbing. They recommended re-siding with Cedar Impressions and replacing the windows with high quality Anderson 400s. They included pricing for a gut renovation of the kitchen (as we had discussed), moving a few walls, and relocating a bathroom. If we had the money, we would do it all.

I never used to have much trouble with credit cards. But now as I try to switch banks (and after buying a house), the new cards I’m getting have minuscule spending limits and every time I make a purchase I’m getting flagged for fraud. I feel like the financial industry is out to get me for daring to question them.

Cooking with fire

Unpacking is hard. We’re in week three and most of my clothes are still in boxes, along with a lot of other things. Tools are scattered about, including some shiny new ones, but we’ve finally gotten rid of the last of the ripped up staircase carpeting, and most of the empty cardboard boxes. We’ve also unpacked much of the kitchen, which required a very intense round of cleaning and sanitizing of some pretty disgusting cabinets, fridge, and even dishwasher! We haven’t touched the oven yet — it’s just too scary.

But I was able to cook a full meal the other night, for the first time in over a month. I made steak, mashed potatoes, roasted asparagus, and a nice salad. Everything came out delicious and just right! It is so nice to have a proper gas stove, and a range hood that actually vents, the combination of which made using my cast iron pan a breeze. The only thing that would make the experience better is a garbage disposal. And a dishwasher that can actually fit our plates. And better water pressure. And more counter space. And…well, I’m getting off track. One thing at a time. Gotta finish unpacking the kitchen, and keep waking up to those beautiful views of the bay.

Everyone is incompetent at everything

How can companies continue to function in this day while being so customer-hostile? First I had a whole fiasco of stupidity with regard to my Verizon FiOS installation. After I got that sorted over the phone, they proceeded to cancel my service and schedule a new installation without telling me. For no reason. Because there was nothing a person actually had to do here, it was all controlled at their “central office.” But because activations and deactivations occur in “batches” and only during certain hours, I had to miss a day of work so a tech could come out, unplug my current cable box, and plug in an identical one with a different serial number. Even he couldn’t explain why. But I had to do it, because I need internet service to do my job.

That pales in comparison to my treatment by Bank of America. That company is generally quite pleasant at the branch level, but at the corporate level, I’ve experienced a pattern of customer abuse and apathy that is unparalleled. They don’t seem to understand the basic fact that putting a $666,666.66 overdraft/hold on one’s account on a Saturday is terrifying. Apparently all that means is there is a fraud concern, but how am I to know that? It doesn’t help that the fraud office isn’t open over the weekend, and I am locked out of all my money for two days. They have no idea how paralyzing that is. They don’t care.

It doesn’t help that, when you change your address, they no longer trust you, no matter how many times you verify your identity with social security numbers, birthdates, and passcodes. They will call you again and again and make you verify the same charges. Yes, I really paid $30 for a subscription to Consumer Reports, thanks for checking on that. Yes, I really did try to have my car serviced, thanks for declining that one. Thanks for the embarrassment. Thanks for not clearing it up after the first, second, third call. Thanks for having an automated call followed by a human caller reading the same script. Thanks for locking me out of online banking. Thanks for not following up. Thanks for getting mad at me for being mad, because you’re just doing your job.

Meghan will attest that I’m super calm on the phone. I don’t yell at the poor abused customer service people. I’m probably the nicest call they receive all day. I respect the difficult predicament they are in. But today I just couldn’t take it. The Bank of America fraud department is tremendously incompetent, and someone needs to tell them that. Every person, every call should tell them how incompetent they are, not thank them for ferreting out that suspicious $25 charge for Angie’s List.

Suggestions for new banks welcomed.

Such friendly people

Our neighbor across the street introduced himself while we were moving in. He said we could ring his bell any time if we needed anything.

And if he wasn’t home, and we required a telephone or needed anything else, just feel free to go inside.

This is both comforting and terrifying to me. Without a doubt we’re really out of the city.

Did I mention that none of our doors or windows have functioning locks?

Mole people

For the last two weeks Meghan and I have subsisted (ha!) in the basement dwelling of a friend of a family member in Hull, the location of our eventual permanent new home. The accommodations were cozy enough, and we were able to begin a preliminary exploration of the neighborhood, including taking the boat into work every day.

I must say, the (independently-operated) Commuter Boat has got to be the best-run service in the entire Massachusetts Bay Transportation Authority portfolio. The reliability and on-time performance is unreal. The snack bar is stocked with beer and wine. On Fridays there is free popcorn. And the views can’t be beat. I pity the poor fools who suffer daily through the indignities of the Commuter Rail, the busses, and the T. I couldn’t be more satisfied, so far, with my new commute.

Yesterday we came aboveground to sign all the final paperwork and officially buy our new house. After so much drama and then our frustrating waiting period, it was wonderful to finally be moving forward. The rain was pouring down as the movers arrived with a big truck full of our furniture and stuff, fresh out of storage. But as we entered the house, I almost wished we could pause all of that for another month or two, and get some serious work done first!

By all accounts the previous owners of our house were a very nice family. They certainly left us a thoughtful note and gift. But the way they lived and treated their house is very different from the way we do things. The more I sit here, the more decay and damage and dirtiness I see. Holes in walls, cracks in ceilings, half-completed home improvement projects, flaking lead-based paint — the works! It is clear why this place took over a year to sell — we have a long road ahead of us to get this house where we want it to be.

It is a great opportunity, because we get to make everything just the way we want it, and everything we do will add value to the home. But it is overwhelming in its scope. We love the bones of the house, and the town, the view, the lot, the neighborhood. And we love the potential in the house, and the vision in our mind’s eye of what it will be. I’m not sure we fully appreciated how much work it would take — and time, and money — to get there.

Presidential run

Last night, unlike the previous several, I didn’t wake up abruptly at 3am to worry about buying a new house. Instead, I dreamt that I was in a long meandering cafeteria line attempting to get a breakfast bagel sandwich, and Barack Obama was behind me. We talked about fitness, and he showed me his new Nike Free shoes. I decided (in dreamland) that now that I was back in school at Brandeis I had to get a pair and start running around the track again.

I think my subconscious self is trying to tell my conscious self something. My conscious self is responding by saying that yesterday it was -2° F. So there’s that.

Americans are moving up to smaller, smarter homes

Suddenly our new 1,800 sq. ft. home feels positively decadent. I’ve been spending a lot of time perusing Sarah Susanka’s books and drawing up plans. Her initial work seemed generally targeted at highly affluent people who could afford extravagant new McMansions. She tries to convince them to downsize by 1/3 or so on raw square footage and instead put the money into building rich detailing into their new homes by spending more per square foot. Her later books talk about remodeling existing smaller or older houses to make them more livable, which is more relevant to Meghan and I. Not So Big Remodeling is fast becoming my home renovation bible. If this is going to work, I’m going to need to become much more handy around the house!

I believe in a world without soap

On the gadget blog Boing Boing the other day I read the strangest post, about living a lifestyle free of soap. The author claimed that he had gone on a year without using any soap or shampoo while bathing, although he still washes his hands and uses deodorant. He claims that going without soap has left him smelling better, with clearer skin and softer hair, than ever before.

The argument basically goes that our bodies have evolved naturally to keep themselves clean, with various excreted oils and such, and washing with hot water only and perhaps some scrubbing is sufficient for cleanliness.

I tried it for a few days. Meghan didn’t notice anything was amiss (or at least didn’t say anything to me), so I guess it was going okay, but I just didn’t feel clean, especially my hair, which was getting sort of greasy. Furthermore, it just doesn’t seem sustainable after activities like skiing, sports, and hiking that can leave one covered with dust, grime, and occasionally blood.

That said, it wasn’t until day 3 (when I gave up on the whole endeavor) that something completely obvious and self-evident occured to me that I had completely forgotten — I haven’t used soap for over a decade, and I’m doing fine.

Wait, don’t run away, let me finish.

I used to have very dry, irritable skin. I always felt like there was a film all over my body. Whenever I got sweaty I got itchy and uncomfortable. I couldn’t stand salt water or chlorinated water. I tried various products and lotions recommended by friends and doctors, until I went to a dermatologist who gave me the advice to just stop using soap. Use shampoo, he said, for areas that are hairy, and just use water and a scrubbing towel on the rest of your body.

That’s what I’ve been doing since high school. I may use a bit more shampoo, a bit more widely spread, when I am feeling particularily dirty, but I don’t really use soap, except of course for hand washing, where I use the foamy stuff. As as result I feel much more comfortable in my skin and while I still don’t love salty or chlorinated water, I have been able to enjoy swimming and the beach, as well as other outdoor sweaty activities that used to make me squirm.

We live in a society that is half over-sharing and half squeamish, and I’m sure my cleanliness habits may make others a bit uncomfortable, but I just think it is interesting. Not using soap has become so basic to me, and so ingrained, that I had completely forgotten I was even doing it. And so far no one has told me I smell too bad.

Hello, world

2011. It’s been a bit dormant around here for a while. No apologies — I resolved long ago not to apologize for a lack of blog posts. But, even as “social media” (primarily Facebook and Twitter) have made personal blogging somewhat obsolete, I think the time has come to reopen this here blog-o-book, because I have Things To Say, if not for anyone particularly interested at the moment, at least for posterity.

At the Tumbridge Vermont fair

So much has happened! A new job, over at this company called EnerNOC. I had to agree, as a condition of employment, to not publish anything that might be construed by anyone as potentially libelous, defamatory, or the least bit hurtful to the company, and furthermore that the company had sole authority over what met that standard, and even further than that, that I would be personally liable well beyond my entire net worth for the real or perceived damages caused by any supposedly negative information I’d theoretically spread about the company, and that I had no recourse to lawsuit or mediation.

Needless to say, blogging about work at EnerNOC will be even more minimal than it was when I worked at Harvard FAS-IT. But I’ll try not to let that discourage me from sharing generalities about technologies I’m working with and interesting things I’m doing and general thoughts on my new corporate life.

Sold the condo. Moving out of the city. It’s a process, a surprisingly long process.

Got engaged. As part of said engagement, seem to have gotten adopted into a whole second family, a really big one to boot. That’s pretty cool.

Growing up fast.

Chasing butterflies in North Carolina

I’ve been having a lot of aches and pains lately. I have been half-jokingly blaming them on getting old (an ancient 27, I am), but it occurred to me today that they are probably actually related to leaving Harvard. In addition to the abundant sunlight that I now lack, being stuck at the back of a cube farm rather than in a nice office, I also no longer get to have a standing desk, so I sit like a schlub all day. And I no longer have a nice track and pool nearby for free, nor do I have the work companions who used to force me to use aforementioned amenities, and pushed me to run longer and swim harder than I might have on my own. I really miss that, and I really miss Mike, JaZahn, and Francisco, in addition to my other old coworkers.

As much as I hate the idea, and as cliché as it is, I guess my new year’s resolution is actually going to be to join a gym. There are no good lap pools in downtown Boston; I’ve conducted a rather extensive online survey. The only solution seems to be the old treadmill. I loathe exercising by standing still. But if I find an above-ground gym, at least I might get some natural light during my lunch breaks.

Stay tuned to this same blog channel for future updates to include:

  • Details of home sale
  • Details of engagement
  • Photos of things
  • Geeky stuff that grandma won’t understand

That ought to keep you coming back! Bye for now.

What would make the Amazon Kindle perfect…

…is if I could buy a real physical book and get a free Kindle “license” to go with it. I’d be willing to pay a few bucks more for the privilege — I’d probably even be willing to buy the hardcover instead of waiting for a paperback.

If I could buy a real physical book to put on my shelf and keep and turn the pages of and touch and smell and bookmark and lend, but also get a code that would give me the convenience of reading the same text on one or more of my various mobile devices, then I’d be happy.

We can purchase a music CD or a movie DVD in physical form and make or receive a digital copy to take with us on our many devices. Why not a book? Why must we give up the essential “bookishness” of the thing in order to have convenience? Why must we pay twice to get a real book and an inferior digital edition?

I’m using my Kindle to read magazines and long-form articles from the web (via Instapaper), and I do grab the occasional public domain book or inexpensive Kindle edition of a commercial book, but every time I purchase a book for Kindle I feel bad about it. I want to read Cormac McCarthy on the subway, and I also want him safe on my bookshelf. I’m willing to accept the limitations of the “license” on a Kindle edition if I can still have a real edition to do with as I please. The publishers wouldn’t be losing sales, they would be gaining them.

Some may think that books are dying, just like physical discs for music and movies. I disagree. But even if they are, look at the new surge in vinyl record sales for evidence that people will pay more for the experience they want.

I learn something new every day about intellectual property

I had some trouble registering my Panera loyalty card, so I emailed their customer support. After a bit of back and forth I received the message below. For explanation, I own the domain name mindwire.org. When I sign up for accounts on web sites, I put in an email address of the form “www.website.com@mindwire.org”. This allows me to track where my email is coming from, since all messages to @mindwire.org come to me. This is a remarkably effective method of revealing how spammers get my email address, and blocking the offending address. This format has never been a problem before now…

I’m slipping away a bit at a time… and all I can do is watch it happen

Author Terry Pratchett speaks out about his Alzheimer’s diagnosis, and what it means to his life. He says that dementia research is chronically underfunded and the spectrum of dementia diseases, including Alzheimer’s, is greatly misunderstood by the public. It is a disease with no hope, because there is no cure, and it affects millions of Americans directly (and many more indirectly) as our population ages.

The old wives tale that carrots improve vision is false. Where the tale originated is quite interesting and unexpected. It was promulgated by, of all sources, the British government, during World War II. Snopes has the full story. And can we take a moment to marvel at the wonder that is Snopes, the urban legends reference pages, still going strong after 15 years?
