Some minor moments in life stun you. Today I learned that the moon looks upside down in the southern hemisphere. Having lived in Buenos Aires for almost a year I am embarrassed that I either never noticed or just forgot.
I assumed I would love modern "flat track" roller derby. I was vaguely aware of its previous incarnation (of the 1940s through 1970s) and it seemed pretty exciting. When I heard it was back and that it had come back led by women and free any ugly sexism, that was supposed to have been a part of it before, I thought, "Great!" A few years ago when I was in Los Angeles some friends were going and I had planned to go along, but at the last minute I couldn't. Without any roller derby near me, and without any friends who go, it just slipped from my attention. And then the other night as a tangent to searching for roller skating videos on YouTube (after watching the so-bad-it's-good Roller Boogie movie) I clicked over to see just what a modern roller derby match looked like.
Ugh. It was awful. I had no idea what the rules were. I tried figuring it out by watching, but it made little sense. And it was just quite possibly the most boring sport I've ever tried to watch (arguably worse than curling, snooker, and sheep herding). Any strategy or logic in flat track roller derby seemed so subtle as to be irrelevant, and despite little of interest seeming to happen the score incomprehensibly climbed faster than any sport I have ever seen (almost 2 points/minute).
Here's what I observed (my impressions before subsequently reading the rules)...
A person or two standing like they were at a starting line. A few clumps of people in front of them, one clump five feet or so ahead, another clump ten feet or so ahead. And then the single people run at the group of people, get caught up, and very likely get pushed out of bounds, at which point they go back to where they started. And this just repeats itself ad infinitum. Occasionally the single people do get past a clump of people, but instead of zooming super fast away or this being the start of something dramatic, the person goes just a few feet and then slows down and returns to the starting line. Whoopie?
The biggest thing I don't understand about modern flat track roller derby is, they've gotten rid of speed, they've gotten rid of a feeling of motion and dynamism, so why have they bothered to keep the players on roller skates? It feels unnecessary and forced. If the argument is that skates make the game harder, well, sure, but why not just play on a slippery surface or wear slippery socks? Roller skates are made to allow people to go fast, to be graceful, to be able to go big distances. The old roller derby clearly understood the purpose of roller skates. But this modern flat track derby requires none of these roller skate features.
I ended up glancing at the rules of scoring, and learned that all points are earned by a team's designated "jammer" passing members of the opposing team (not including their jammer); and both jammers I gather are active on the track at the same time.
And so I wondered, what happened? Why was I expecting this to be exciting? Had I misunderstood what roller derby used to be? I clicked on a YouTube video of a 1950 New Jersey vs. Philadelphia roller derby match (separate male and female matches) and wow, it was as I thought, that game made sense, that game was much more fun to watch, stuff actually happened! The people were constantly in motion circling the track, which is somewhat enjoyable to watch in and of itself, and because everyone is already at speed they can then do a great many interesting things to try to move the jammer forward, like one or more people sacrificing their own speed/energy to propel their jammer forward, by whipping them forward with their arms. Also because they were at speed and the track is banked people can quickly fly to the inside or outside of the track to try and get by, akin to auto racing. And because there was an outside railing the jammers are not constantly going out of bounds every two seconds and needing to restart.
I assume that the primary reason the sport has become so insufferably boring is because of the elimination of the banked track. Moved out of the velodrome, speed is severely limited. At speed the centrifugal force would fling anyone not paying attention out of bounds. With a flat track you could not have people smoothly loop the track because every turn would be a chaotic mess. No doubt they moved the sport out of the velodrome because velodromes are hard to find, and they were able to broaden the sport as a result. But, having gotten rid of the banked track they had to get rid of the constant circling motion of the teams, and having gotten rid of that, well, everyone is mostly just standing around in slippery shoes. Maybe some rule changes could have compensated, made the sport still interesting, but I don't know.
China mystifies me. Their recent military parade celebrating the 70th anniversary of the end of WWII is one confounding example. They stage a huge parade to show off all their offensive and defensive weapons, shut down the city days in advance to make sure people are out of the way and the air is unpolluted, invite some foreign dignitaries, and ban their citizens from watching the parade in person (no standing on balconies, no opening windows, no looking out windows, no standing on the street watching, no watching from cars, no photos, etc.); presumably there is approved news coverage they can watch/read. But, what a bizarre idea? I thought events like this were meant to impress the people, involve the people, akin to the pre-war Nazi parades. When you have to keep the people away out of fear of activism or terrorism then the parade seems more an admission of abject defeat than triumph.
Cults have always fascinated me. It is only natural as several relatives of mine have been members of organizations which most people, myself included, would consider cults. Of course these relatives don't believe their groups are cults, no cult member ever does.
The other day I had occasion to think about cults and it struck me that cults are really just magic shows on a grander stage, and with far more and lingering audience participation. Everyone who joins a cult joins to see "magic" worked in their lives. They can no longer wait for or no longer trust the more traditional routes to their better selves. And so they seek out or end up at the doorstep of any of thousands of cults, religious or corporate, ready to be deconstructed and reconstructed. And if they give the group their money, their time, their compliance, and often a bit of voluntary servitude, they just might become the people they imagined was lying beneath all the accumulated baggage from their many pre-enlightened lost years on this good earth.
But the magical analogy goes further, I think. Because a magician's show is built as a collection of tricks. And the tricks themselves are clever combinations of many discrete techniques chained together (e.g., the "force", the "dual reality"). These individual elements form the well used language of magicians. Each element might come in many variations, but at their core are the same trick. Most magicians go to great lengths to make their shows feel new, fresh, exciting, draw in new paying audiences, but the reality is, there is little new in magic. The presentation has been improved, the patter upgraded, but the fundamental building blocks and end result of the tricks remain the same. And so, too, with the cult leaders, the gurus, and their groups. For hundreds of years (at least) the new guru has relied mostly on repackaging the old guru's teachings and presenting them in language and formats more palatable to each more enlightened generation. The Eastern-heavy new age movements of the 1970s become the more sophisticated Western, corporate awareness training. But what's different about them really?
Cult leaders manipulate experiences, emotional states, and outcomes using a clever combination of discrete (primarily psychological) elements. For example, they might use "breaking", wherein members or staff within the group are encouraged/led to confront and challenge another participant in the group. It is a simple trick. When you have multiple people ganging up on someone using strong and challenging words/ideas, in a context in which the individual cannot easily escape, because leaving would be socially unacceptable, painful, awkward, etc. then you can create in that individual considerable doubt, desperation, and compliance, almost regardless of the content of the challenges. We humans are social creatures, built to respond to significant doubts leveled at us with significant doubts bubbling within us.
Imagine if this happened in your life, perhaps you are at the wedding of your brother and four close family members come up to you saying they need to talk, they all tell you that they love you and that they are worried about you, that they believe your job is not good for you. You actually like your job. You politely try to explaining that to them, but they begin ad hominem attacks saying that you are just defending your job because you are too cowardly to face the real truth that your career is going nowhere. You try to end the conversation and move away but they follow you and insist that you are leaving the conversation because you know what they are saying is really true. They say you are being disrespectful to move away because they are doing this out of love. You stop. You feel trapped and listen to them some more. After some period of time the episode ends, either because you have capitulated enough or because they feel the important seeds of doubt have been planted. If you had even the slightest doubts about your life, your job, your career, their confrontation surely magnified them. Our brains are not meant for such circumstances. These people seem to care about you, seem to have your best interests at heart, why would they lie to you? It seems inconceivable. They are saying everything so strongly, surely there must be some merit to what they are saying, usually when people speak so strongly it is because they have some basis for it. You do want to move ahead in your career, maybe you are not moving as fast as some friends of yours, maybe you have seen others get a promotion you thought you deserved. In a matter of minutes or hours you go from happy with your job, with the normal level of dissatisfaction and hopes for more successful tomorrows that practically everyone feels, to thinking that perhaps you should quit your job, change careers, something. Everyone has insecurities, doubts, weaknesses and cults know a host of methods by which they can magnify them to motivate you to some end, their end (which they insist is really in your best interest).
Another technique they use is "love bombing", creating situations and environments in which people experience a heightened sense of connection with those around them to the point that they feel a heightened sense of love from those around them. Who wouldn't respond positively to feeling more love from those around them? Participation in the group activities creates a feeling of love, an experience that can't be easily be gotten on demand outside the group. So you are trained to keep going to meetings. There are many, many tricks that cults and groups use to gather and control their members. Some do it for power, some do it for money, all do it for allegedly noble reasons.
The feeling of awe the magician and the cult leader can generate is muted once you know some of their tricks, and see them being worked into their acts. The magic is still fascinating, but no longer short-circuits your rationality. In the cult setting, when you see most of a room of a hundred people reduced to broken, sobbing masses expressing their inner most limiting beliefs you do not ascribe this to the power of the truths being revealed by the leader, you ascribe it to the power of the psychological trick being used to manipulate the group. You know that almost any cult leader could create the same response in any similarly ready group of people with "truths" that almost any rational person would reject. The technique matters, not the guru, and certainly not the underlying truth. But everyone in a cult always thinks on some level that they are smarter than that. Just ask the participants in the Milgram experiment, they believed they were immune to authority.
The question I would ask of any cult or group is, what percentage of your members 10 years after first being introduced to the group believe the experience was positive and worth the time and money they invested in it? I would suspect that for almost all groups which use cult-ish methods the percentage of people indicating they were satisfied with the experience 10 years on is less than 10%. I believe this anecdotally based on the people I have met who have been in cults, the experiences I've read about, and my belief that those entering these groups did not do so with sober minds, most of them were duped on some level, had their wills bent into participation. They did not make free, sober, rational decisions to participate. And this low satisfaction score (if it exists) would prove to me that the groups are fraudulent. The groups will blame the former members and say they chose to give up too soon, that they weren't the right sort of people, that they didn't keep learning what the group had to offer, that others have benefited so the people who didn't are solely responsible for their lack of benefit. But, to me it's a hollow kind of defense. People routinely make succeed and make millions selling bogus diet pills. They achieve success because most people won't ask for a refund (most people will be as fat or fatter but will be too embarrassed or afraid of confrontation to complain), b) they always recommend combining exercise with the pills (and exercise does positively correlate to weight loss), c) the placebo effect will guarantee some percentage of users will find some new will to modify their behavior because of powers they ascribe to the pill. Just because 10% of the people buying a fat loss pill are satisfied doesn't mean the product contains any ingredients which actually work.
There is always a new cult, a new group selling a new method to solve a very human problem, an existential dissatisfaction, a sense that life can and should be more than it is. It surprises me that cult-entering people can't see the pattern. Can't see the endless stream of cults formed and reformed, regurgitating the same (but now repackaged) esoteric "truths". But, alas they will not... Cults will never run out of followers.
It reminds me of a line from the Sherlock Holmes story A Case of Identity by Sir Arthur Conan Doyle. In it Holmes decides not to reveal to his client that her missing lover was actually her step-father trying to wound her into life long maidenhood so he could have her money. Holmes explains to Watson his decision to keep quiet about it, "If I tell her she will not believe me. You may remember the old Persian saying, "'There is danger for him who taketh the tiger cub, and danger also for whoso snatches a delusion from a woman.'" (I try to ignore the contextual misogyny, and see it as a truth which applies to deluded men and women alike.)
And I may be wrong of course... but I do feel I at least have the carcasses of many abandoned cults and many disaffected followers adding weight to my side of the argument.
Few things in American history confuse me like the U.S. Civil War. I have spent time surrounded by its monuments, memorials, and museums, living for a few years outside Gettysburg, PA. What I can't quite work out is why...? Why would Northern brother, cousin, uncle be so willing to fight to their death against their Southern brother, cousin, uncle just to keep the United States of America as one nation? So many questions...
Why is the right to secede not a right core to a democracy? If a state feels so at odds and unrepresented by their parent nation why should they not be able to withdraw from it? Is this freedom not one that should be most sacredly preserved when a nation is formed from many states?
In the Civil War the Northerners were certainly not primarily fighting for the freedom of African Americans. That I could have understood as a reason to go to war, to liberate an oppressed people. Giving your life for that sort of a cause makes sense to this modern, arguably enlightened man. But while the North was somewhat more enlightened than the South on this issue, they certainly did not see African Americans as equals and it would be a rare Northerner willing to die for that particular cause.
Why could the North not just let the South go? I vaguely understand the Northern industrial and free farming folks were in an economic battle with the almost wholly agrarian South and its plantation and cheaper slave labor. But that's enough for a war, and not just a civilized parting of the union with peacefully signed free trade agreements?
What would it take for me now to be willing to take up arms against my cousin, uncle, or brother? I can imagine nothing, certainly not a mere secession. But 750,000 dead soldiers can't be wrong, they must have deeply felt their reasons were the right ones. I just wish I understood them.
The news is filled with people bemoaning the ACA (aka Obamacare). I am not one of them. My situation has greatly improved. I was a single guy, no kids, early forties, paying $650/month for a HIPAA plan with very high copays and $5,000 deductible. I am now paying $370/month for a platinum plan (10% copay) with $500 deductible. I couldn't be happier.
I have always been a non-smoker, non-drinker, non-drug user, and reasonably healthy. But no insurance company would give me an individual healthcare plan, not since I was 25. I was rejected without explanation by many companies. Presumably they rejected me based on pre-existing conditions, but my pre-existing conditions were trivial, some mild depression and anxiety, but never hospitalized for that or anything else. I finally got insurance through work, and was able to transition to an individual HIPAA plan after becoming a consultant. I could not switch to anything better or cheaper, though, still no company not forced by HIPAA to take me would have me. And I looked into the "high risk" pool coverage (the only other option) that California offered and was shocked to find it was a) expensive, b) had a long waiting list to get in, c) provided really low and weak coverage. So, until the ACA rolled out January 1, 2014 I was stuck.
The news reporting of others' experience with ACA plans has me a little confused. The vast majority of people seem to have had really lousy policies which didn't offer much coverage and they are now complaining that they are forced to buy a more comprehensive policy and thus pay more for it. I have somewhat limited sympathy for those situations, because I think the reality is that those cheap policies often just wind up shifting the cost to everyone when someone who has one of those policies gets seriously ill, finds their policy doesn't provide adequate coverage, and goes bankrupt or otherwise requires the hospitals and debt agencies to eat the loss when they can't pay their bills. The people buying those policies may claim that it's the right plan for them, the right price, and that it's just what they need, but I have to believe on a macro scale that's just not born out, that the rest of society takes a financial hit for their stinginess. If you know that to be false, please correct me. For the remaining minority of people making the news whose prices have gone up significantly without an increase in coverage, and without any offsetting tax reduction, I do feel very badly, and hope cheaper options become available, or other corrective measures are taken.
If nothing else, I am very glad that the health insurance system was finally forced to move away from the cruel and capricious system of excluding people because of pre-existing conditions, it was a savage system that usually unfairly penalized people who had no hand in their conditions, leaving them to fend for themselves or pay dearly for rotten coverage. Whatever people may say about the ACA, at least it did away with that...
As I approach my 40th birth I can't help but reflect on the folly of my having attempted to be a responsible human being. All around me I see the irresponsible inheriting the Earth, delighting in its rewards, and it makes me feel rather foolish and rather sad, for all I've missed out on.
There are two primary areas where my attempt to be responsible has seemed grossly the wrong thing: having children and home ownership.
I have always strongly believed that being a parent is the most important thing one can do, and one should not do it until they are mentally and financially prepared. No parent is ever perfect, nor perfectly prepared, but the child suffers for the flaws of their parents, so it seems only reasonable that one would minimize their negative impact on their children, while maximizing their positive impact. And it seems only reasonable that one would wait until they were in a relationship likely to last forever before kids were even considered. But all around me people flout these rules, with no ill effects that anyone seems to openly acknowledge. The harm done to the children is discounted, ignored as though that harm was unavoidable, as though all children can expect to be harmed in one way or another, so what's the big deal?
I have some relatives and friends who've had multiple kids with different fathers, having chosen to form unstable relationships, having chosen to forgo effective contraception, having chosen to engage in no serious employment, and having chosen to continue using drugs and alcohol. And while no doubt everyone might casually acknowledge some poor choices, all choose to focus instead on the joy of the existence of these children, and the "marvelous" job the mothers are doing despite the situations they've created, and the choices they continue to make. And I mean no discredit against the positive things the mothers do, and I certainly mean nothing against the innocent children brought into the situation, I just can't help but feel selfishly frustrated by the inequity of it all. That I, who would be a wonderful father, who has made many, many right decisions for a child's benefit, am denied that joy, that satisfaction, that comfort, that opportunity, etc. while others who have taken the role so much less seriously get all those wonderful things. It feels so cruelly unfair. Obviously there's no one to blame, other than perhaps myself, or perhaps the universe. It is I who has chosen to obey a rule I accept as in a child's best interest, and it's the universe which has created the other rules by which we are all bound.
Far less emotionally significant, but certainly frustrating nonetheless, I can't help but remark that I who have tried to be responsible by not buying a house I couldn't afford with a loan I might not have been able to pay back, am deeply annoyed and feel hard done by that others who made reckless home ownership decisions based on bogus beliefs in the housing market and interest rates are receiving sympathy and financial assistance. Why not help those who did the right and good thing, who did not place our nation and economy at risk selfishly? I understand the need to prop up those who have gotten themselves into trouble, lest our economy collapse even further, but how tired I am of irresponsibility being effectively rewarded, and with the resources and sweat of those who did no wrong.
Ah well, that's my useless, self-indulgent gripe of the week.
Complete Guide to Installing, Configuring CyanogenMod 7 Stable Release (Android 2.3, Gingerbread) on the Nook Color
If you are new to Nook Color operating system and install options, I strongly recommend reading this guide to picking your Nook Color operating system and installer. And if you're just starting to explore what Android is and are a little hesitant, you can always try Android for free on your computer with a virtual machine.
Within 30 minutes your Nook Color can be running the latest stable, available version of Google's Android 2.3 (Gingerbread) OS (technically the CyanogenMod 7 Stable manifestation of it), and thanks to its use of the SD card, all safely achieved without altering your existing Nook Color's setup or violating the warranty. Included in all the new features, performance benefits, and elevation of your own personal coolness, you get Bluetooth support. The Nook Color can do VOIP (e.g., Skype), GPS navigation, sending music to wireless headets or stereos, and much more!
My goal in this document is to help less technical people through the slightly more technical and slightly more we-assume-you-know what-you're-doing verygreen's CyanogenMod 7 (CM 7) to SD install instructions, covering things left out, additional problems you might encounter, and configuration you might want to do post install. If you have any basic questions or run into trouble, please check out this Nook Color Modding FAQ which might save us both some time.
Be aware, I experienced lingering and frustrating stability and file system corruption issues with several installs to several SD cards. Other people are not having this experience, but if you do be aware that your SD cards may be too "fast". Your choice is then to try and find other workable SD cards or do an eMMC (internal memory) install, such as you'll find in my guide to phiremod install on the Nook Color.
Step 1: Installing CM7 Stable to your SD card
The first step is to follow verygreen's instructions on how to take the SD card image he made, combined with the latest updated CM7 install, combined with the Google apps pack (gapps) to get a bootable system.
Before you begin, though, let me give you some tips.
- Windows users will need Win32DiskImager to flash the requisite .img file to your SD card. It's free, download Win32DiskImager now.
- Mac / Linux / FreeBSD users will use "dd" to flash the requisite .img file to your SD card. The command you will execute looks like:
# dd if=generic-sdcard-v1.1.img of=/dev/sdcard
If needed, replace /dev/sdcard with the real path of your mounted SD card and specify the real path of the data image (after unpacking the gz version you downloaded).
- I strongly recommend against using class 10 rated SD cards! Testing over several days proved that my system would not run reliably (tons of "force close" errors and the file system reverting to read-only) on a class 10 rated card, the Patriot LX series. Whereas the system works flawlessly on my PNY class 4 card, which cost less than half as much and actually operates just as fast, according to SD Tools it writes at 12 MB/s and reads at 84 MB/s read, which exceeds class 10.
- If you insist on using a class 10 card, the verygreen install script will probably hang when it goes to create the disk structure. A workaround for this is to first burn the image to a working (and dirt cheap, $7-10) class 4 PNY or Sandisk (or other) microSD card (of equivalent or, to be safe, smaller size) and then when you've got the install completed clone the microSD card by using Win32DiskImager to create a .img file of the working class 4 SD card and then write that image to your class 10 SD card. It's a hassle, you'll be waiting 15 minutes to read, 15 minutes to write, but it works! And you've now got a backup to boot. Assuming your class 10 was larger than your class 4 SD card you can then expand the virtual SD partition using any non-destructive partitioning product (the partition is fat32) so that you get all your space used. If you've got Windows 7, use its Disk Mangement feature to safely expand the partition, if you've got another Windows version you may need to use EASUS's Partition Master Professional Edition ($19) or Acronis' DiskDirector ($49).
- The CM7 build you want is "update-cm-7.0.0-encore-signed.zip", so make sure you get that one! (Obviously if you're reading this document in the distant future, make your best choice!)
- You might want to initially avoid the Dalingrin OC kernel/ROM upgrade instructions for now, I'll cover that separately below.
- If you get hung up trying to install the Google apps pack because it seems like the recovery console isn't installing it, you may be going into the wrong recover mode or no mode at all! Turn off the device and then turn it back on holding both power and N for 6 seconds, one to two seconds after the "Touch the Future of Reading" comes on the screen. You'll see the Linux penguin at the top and a bunch of console messages, one of which will indicate it's looking for "gapps". If you don't see that you're not in the right recovery screen!
Those tips being given:
Go to and follow carefully verygreen's CyanogenMod 7 (CM 7) to SD install instructions!
The entire process will only take you about 15 - 20 minutes. If you were using a class 10 card you can do the class 4 to class 10 clone at this point, or at the very end when you've got everything set up, it's your choice.
Step 2: Turn on Bluetooth (optional)
If you're ready to turn on Bluetooth, there's a trick. If you don't do this, Bluetooth will just refuse to turn on / be enabled.
- Turn off wifi (Settings > Wireless & Networks > Wi-Fi)
- Turn on Bluetooth (Settings > Wireless & Networks > Bluetooth)
- Turn on wifi
It seems a bit odd, but that's what you have to do. From then on out it'll work fine.
Bluetooth Keyboard Instructions
Pair as you normally pair a Bluetooth keyboard, that all works just as you'd expect. But, if you don't do this next step you'll likely want to throw your keyboard and Nook Color out the window within the first 30 minutes of typing. When you type on your Bluetooth keyboard the virtual keyboard will very likely appear, or re-appear if you've hidden it. I am not sure why this is. You close the keyboard, you type, maybe it stays closed for a moment or two, but invariably it opens up again. And, because it's open not only do you have much of your screen real estate wasted by a keyboard you're not using, your physical keyboard presses will often linger long enough to pop up the Gingerbread character selector. In other words, type "e" on the keyboard and about 5% of the time it will think you held "e" down in order to bring up the list of international "e" variations, which you then need to close. And, as if that's not annoying enough, the predictive text completion that will go on with the virtual keyboard open will lead to sometimes sluggish responses to your keypresses, and even missing text. The solution? Buy and install the Null Keyboard ($2)! It's money well spent. You install it, enable it in settings, and then when you are going to use your BT keyboard you hold your finger down on an input box for a few seconds, it asks you to choose your input method, you choose Null Keyboard, and voila! You can now type on your BT keyboard with joy. And when you put away the keyboard don't forget you'll need to switch the input back to your Android (or Gingerbread) keyboard next time you need to type with the virtual one.
Step 3: Adding Important Apps
CM7 is great, but you'll need some other free apps to really get the best experience out of it. The list had gotten rather long so I have now put it on its own page. I strongly recommend you go now and install all of the free Must Have Apps for your Nook Color.
Obviously you can add more apps beyond those, but you walking that list you will cover the basics and be in good shape to proceed.
Step 4: Overclocking!
If you want to at this point you can try some overclocking. It appears to be pretty stable, pretty safe, and potentially makes your Nook Color 40% faster than when you bought it! It can arguably run as fast as the Samsung Galaxy Tab!
This process is pretty simple, it involves replacing the uImage file on the SD partition of your microSD card with an alternative that has been "hacked" for performance (and/or features). The one everyone is using now for CM7 is Dalingrin's.
- Download the 2.6.29 Dalingrin OC kernel (or earlier version, DO NOT DOWNLOAD THE LATEST) for CM7 on SD card. You do not want to download the latest, it requires a test build of CM 7 that isn't stable. Do not pick the wrong kernel! Follow the link in Dalingrin's kernel announcement thread for the “Froyo and CM7 kernel”. Then choose the most recent dated folder, then pick the kernel called “update-CM7-dalingrin-OC-sd-MMDDYY.zip” (where the MMDDYY is replaced with the date of the recent version). MAKE SURE YOU PICK THE ONE WITH "CM7" AND "SD" IN THE NAME!
- On your Nook Color go into the installed "Terminal Emulator" app, type "su" to make you the superuser. You should see the prompt change to "#" instead of "$". If this doesn't change, close out and try again. I've seen Terminal Emulator seem to have issues getting super user permission at first. Once it has accepted your "su" and the prompt changes, type in "rm -rf /data/dalvik-cache/*". As soon as this is done, shutdown your Nook Color (hold the power button down, then choose power off) and put the microSD card in your computer.
- Rename the existing file in your mounted SD card "uImage" as "uImage.original".
- Open the kernel file you downloaded and copy the "uImage" file inside it to the SD card, so it sits next to the original uImage file.
- Safely eject the SD card from your computer, pop it in your Nook Color and power on!
Your Nook Color will now be running the latest kernel!
To turn on the overclocking, go to Settings > CyanogenMod Settings > Performance > CPU Settings > Max CPU Frequency.
If something goes wrong and your device won't boot or in some other way seems seriously screwed up, just shut down, pop out the microSD card, put it back into your computer and delete the "uImage" file, and rename the "uImage.original" to "uImage". Dealing with any problems is beyond the scope of this article, your best bet for support would be the people in this thread. And don't forget, we're doing all this on the microSD, you can always pop-out the microSD and your original Nook Color is still there.
Step 5: Backup
You really should back up at this point. Shut down and make an image of your SD card if possible. Things can easily get screwed up, corrupted, etc. with an alpha-stage release like this, so it's best to be able to easily get back to where you were. I've seen a lot of things get corrupted and had to reinstall more than a few things. Better safe than sorry. Also, use Titanium Backup to backup your app data!
Step 6: Keeping Up to Date
Once you've got your system up and running you'll inevitably want to update it as new bug fixes and features are released. This process is a lot less painful than it used to be, thanks to the clever way these installs are distributed and also thanks to the great apps available for backup and restore.
I do not recommend people update to the 2.6.32 kernel yet, since it requires the test/dev version of CM 7 and isn't ready for prime time yet. If you do you'll also need to update u-boot file.
The details of how you do this are too big to insert here, but can be found in this separate guide to keeping your Nook Color up to date.
Post Script - Addendum
If you see a lot of "force close" events happening randomly or you find that files you were working on suddenly become unusable, your problem is most likely with your SD cards. You can try to find other SD cards that will work, or you can try an eMMC (internal memory) install such as the one I describe in my guide to phiremod install on the Nook Color.
I've been running CM7 for a week now, and tried quite a few kernels along the way. I am mostly thrilled. My setup has been stable ever since I ditched the class 10 rated cards. Everything I need works, including most notably Bluetooth! Admittedly the range is terrible, but good enough for my purposes, and I'm sure range will improve soon. Wifi is stable, since the device never sleeps. And battery life is good, though because the device never sleeps it isn't nearly as good as a stock Nook Color. The video is works at very respectable frame rate since the RC4 update. And I've had no trouble with overclocking.
CM7 Versus Froyo
CM7 feels much faster than Froyo, the responsiveness of the interfaces, the boot time, maybe it's all in my head, but hopefully not. One major issue gone is the crippling slowness of Market downloads/etc. I experienced with Froyo on a class 4 SD card were totally gone on CM7 with the same class 4 SD card.
Don't Forget to Use Your Internal Memory!
You can access the contents of your Nook Color's original, internal memory within your CM7 OS by browsing to /mnt/emmc with an appropriate file manager (see above). In this way you can still use most (5+ GB) of your internal storage for things like music and video files (not apps, since the system doesn't know to use that location). So don't forget that space is available if you need it.
Responding to Force Close Messages
Unfortunately at this stage you can expect some instability in the OS, and this seems to manifest itself primarily as "force close" messages when an app fails. My experience suggests the best thing to do when you get any such message is to reboot. On my system a force close can correspond with the file system having become or about to become read only. I assume the OS tries to protect itself by becoming read only and once the system starts going, baby, it's gone! So, the best policy seems to be to immediately reboot, and if you have any more problems on reboot do the "rm -rf /data/dalvik-cache/*" and reboot again.
One particular force close message I got frequently was from Google apps ("gapps") and Google framework. I suspect the issue related to network issues, perhaps it trying to run when the wifi wasn't yet reconnected after a wake. I was able to eliminate this by disabling the automatic sync, go to Settings > Accounts & sync > Auto-sync and set it to unchecked. This means my email won't automatically come in, but I can manually retrieve it by choosing "Refresh" from the Gmail menu. Personally, my phone alerts me on every email, so it's not vital for my tablet to do it as well. Warning, do not uncheck the "Background data" checkbox on the same page, Market and a few other more vital things will refuse to work if you do that.
Another cause of force closes seems to be corrupted installs / configuration / filesystem. If an app in particular isn't working try the following, first one, then if you're still having the problem go to the next one, and so on:
- Clear dalvik-cache and reboot (rm -rf /data/dalvik-cache/*). Then reboot.
- Use ClockwordMod's permission fix option. Then reboot.
- Backup your data related to the app (using Titanium Backup) then uninstall and reinstall the app using Market. And only if the app is working try to restore the data (only) from the backup you made.
This approach has resolved several different force close problems I had.
(FYI, ClockworkMod still crashes and reboots the NC when I try to back up a ROM, and refuses utterly to enter CWM recovery on a reboot.)
As I mentioned above, further testing has suggested that most of my were the result of my using a class 10 card. Since I cloned my SD card from class 10 to class 4 I've seen almost no instability, and what problems remain are likely down to problems with individual applications and their compatibility. I'd encourage people to just use class 4 or 6... And as I mentioned, my PNY class 4 cards all perform as well as my class 10 card, but with greater stability!
Dalingrin is frequently releasing new kernels, and it's tempting to jump to the latest, but always check the change log first (in the beginning of his thread) to see if it resolves any problems you have. Sometimes you may wish to hold off and see how others embrace it. Ultimately it's a matter of the bugs you can live with versus the ones you can't.
I'm thrilled with my new mobile set up, which was only possible with the Bluetooth ability of CM7! I used to do the same with my OQO Model 02, but sadly that device was a little before its time...
(The iGo Stowaway keyboard is the single great gadget I've ever had! I got it for $30 at a Tuesday Morning discount store, and four or five years later it's still the best mobile keyboard I've seen, and they are so loved you can't get an old stock one online for less than $175!)
The faithful like to argue that the universe could not have created itself out of nothing in the moment of the Big Bang, that the idea is absolutely nonsensical. I agree. But what seems so curiously hypocritical to me is that those faithful are promoting exactly the same sort of nonsense, that either God somehow created Himself out of nothingness or that He somehow always existed. Both those something-in-spite-of-nothing beliefs make no more sense than the prevailing scientific theories about how matter and energy might have come to be in the Big Bang. Forced to choose between multiple ridiculous ideas, I'll choose to believe the most direct and least complicated one.
