Education

Journal Journal: HOWTO: Run an educational system 1

The topic on Woz inspired me to post something about the ideas I've been percolating for some time. These are based on personal teaching experience, teaching experience by siblings and father at University level and by my grandfather at secondary school, 6th form college and military acadamy. (There's been a lot of academics in the family.)

Anyways, I'll break this down into sections. Section 1 deals with the issues of class size and difference in ability. It is simply not possible to teach to any kind of meaningful standard a group of kids of wildly differing ability. Each subject should be streamed, such that people of similar ability are grouped together -- with one and only one exception: you cannot neglect the social aspect of education. Some people function well together, some people dysfunction well together. You really want to maintain the former of those two groups as much as possible, even if that means having a person moved up or down one stream.

Further, not everyone who learns at the same pace learns in the same way. Streams should be segmented according to student perspective, at least to some degree, to maximize the student's ability to fully process what they are learning. A different perspective will almost certainly result in a different stream. Obviously, you want students to be in the perspective that leads them to be in the fastest stream they can be in.

There should be sufficient divisions such that any given stream progresses with the least turbulence possible. Laminar flow is good. There should also be no fewer than one instructor per ten students at a secondary school level. You probably want more instructors in primary education, less at college/university, with 1:10 being the average across all three.

Section 2: What to teach. I argue that the absolute fundamental skills deal in how to learn, how to research, how to find data, how to question, how to evaluate, how to apply reasoning tools such as deduction, inference, lateral thinking, etc, in constructive and useful ways. Without these skills, education is just a bunch of disconnected facts and figures. These skills do not have to be taught directly from day 1, but they do have to be a part of how things are taught and must become second-nature before secondary education starts.

Since neurologists now believe that what is learned alters the wiring of the brain, the flexibility of the brain and the adult size of the brain, it makes sense that the material taught should seek to optimize things a bit. Languages seem to boost mental capacity and the brain's capacity to be fault-tolerant. It would seem to follow that teaching multiple languages of different language families would be a Good Thing in terms of architecturing a good brain. Memorization/rote-learning seems to boost other parts of the brain. It's not clear what balance should be struck, or what other brain-enhancing skills there might be, but some start is better than no start at all.

Section 3: How to test. If it's essential to have exams (which I doubt), the exam should be longer than could be completed by anyone - however good - within the allowed time, with a gradual increase in the difficulty of the questions. Multiple guess choice should be banned. The mean and median score should be 50% and follow a normal distribution. Giving the same test to an expert system given the same level of instruction as the students should result in a failing grade, which I'd put at anything under 20% on this scale. (You are not testing their ability to be a computer. Not in this system.)

Each test should produce two scores - the raw score (showing current ability) and the score after adjusting for the anticipated score based on previous test results (which show the ability to learn and therefore what should have been learned this time - you want the third-order differential and therefore the first three tests cannot be examined this way). The adjusted score should be on the range of -1 (learned nothing new, consider moving across to a different perspective in the same stream) to 0 (learned at expected rate) to +1 (learning too fast for the stream, consider moving up). Students should not be moved downstream on a test result, only ever on a neutral evaluation of some kind.

Section 4: Fundamentals within any given craft, study or profession should be taught as deeply and thoroughly as possible. Those change the least and will apply even as the details they are intertwined with move in and out of fashion. "Concrete" skills should be taught broadly enough that there is never a serious risk of unemployability, but also deeply enough that the skills have serious market value.

Section 5: Absolutely NO homework. It's either going to be rushed, plagarized or paid-for. It's never going to be done well and it serves no useful purpose. Year-long projects are far more sensible as they achieve the repetitious use of a skill that homework tries to do but in a way that is immediately practical and immediately necessary.

Lab work should likewise not demonstrate trivial stuff, but through repetition and variation lead to the memorization of the theory and its association with practical problems of the appropriate class.

Section 6: James Oliver's advice on diet should be followed within reason - and the "within reason" bit has more to do with what food scientists and cookery scientists discover than with any complaints.

Section 7: Go bankrupt. This is where this whole scheme falls over -- to do what I'm proposing seriously would require multiplying the costs of maintaining and running a school by 25-30 with no additional income. If it had a few billion in starting capital and bought stocks in businesses likely to be boosted by a high-intensity K-PhD educational program, it is just possible you could reduce the bleeding to manageable proportions. What you can never do in this system is turn a profit, although all who are taught will make very substantial profits from such a system.

Journal Journal: Oh, shit. 28

About a year and a half ago, my wife met a really cool lady while doing community theater. Her boyfriend turned out to be a computer nerd, like me. In that year and a half, my wife and this woman grew very close, having similar interests and character. Although I tried to befriend the boyfriend, he always seemed distant. We knew, from his girlfriend, that he had had a "bad" childhood. We just never knew how bad, I guess. Yesterday at six AM, their house was raided by a fifteen man task force including state police, the FBI, and the district attorney's office. Because they had been investigating him for a year, and had the house under observation for a month, they knew they did not need the SWAT team for a flash-bang entrance, as was common in these cases. They were looking for child pornography, and they found it. Not "barely legal" stuff, two to six year olds, in violent and incestuous situations. He admitted guilt, at least according to the police, who questioned him away from his girlfriend. Yes, I realize that could be an interrogation tactic, but he also never protested his innocence to her, and seemed to know exactly why the raid was happening.

The raid was professional and the police were amazingly courteous. They found about an eighth of pot and quite a bit of paraphernalia, and asked whose it was. She admitted that her mom is an old hippie and had left a bunch of bongs there, but the rest was hers, that she used to calm herself down because she had hyperthyroidism, which is true. They let her keep everything and joked that, after this, she'd probably need it. The police doing this kind of work probably look on pot like they look on jaywalking, technically illegal, but not worth their time. They had a list of specific files that had been downloaded and came prepared with the utilities to scan any electronic device or media on the premises. The fact that he used Linux didn't phase them for a second. She gave up all the passwords she knew. As soon as they found the first match, about an hour and a half into things, he was cuffed and taken away. The raid lasted another three and a half hours after that, as the police methodically searched for additional evidence.

She had class, and needed her laptop, so they scanned that and gave it back to her right away, but she couldn't go to class because, if you leave the scene of an investigation, you can't come back until they are done. Which meant she couldn't go buy cigarettes, either, she was out, and none of the police smoked, the poor thing. So she pulled some hair out, strand by strand. The police had a rookie with them they assigned to her, probably like "Watch what we do and make sure she doesn't freak out." They set up two tables in her driveway. Anything potentially dangerous was brought there, as well as electronics and media. Other things were opened, searched, and placed on the floor. They took all hard drives and electronic components. They searched stacks of blank CDs, looking for any hidden amongst the blanks. They took all hand labeled CDs. They felt all cushions carefully, but not finding anything, did not rip them open. They opened all boxes, jars, bags, etcetera, and searched them.

I know all this because we spent about five hours last night going over it with her. If you ever have a friend go through a traumatic experience, this is the best thing you can do for them. Just listen, as they say the same things over and over again. Heck, when they slow down, ask questions to get them going again. Encourage them to show their feelings about it, too, if they cry or rage or shake or whatever, so much the better. The earlier you can get them to do it, the better, because (according to some psychological theories as I understand them) during traumatic, emotional events, the rational mind shuts down and disassociates at least a little. The experience is stored in memory as an undifferentiated lump with heavy emotional triggers attached. If it isn't processed, anything associated with the event can trigger strong emotions, once again causing the rational mid to shut down a little. Having one's rational mind shut down all the time is sub-optimal. She is going to clean up, move all his stuff to storage, and smudge the place with sage, which normally would earn an eye-roll from me, but this is exactly the place for that ritual. It's not magic, it's psychology.

The thing is, she had broken up with him the week before, and it was under consideration for a long time, because he just couldn't get his shit together after his dad died two years ago. He hadn't worked in years, he didn't do anything around the house, he just didn't do anything. He never wanted to hang out with me, even though we have similar interests and had fun conversations at parties. She would come home and find him crying on the couch. He doesn't remember much of his childhood, what he does remember is terrifying. His dad was a hoarder, and they were divorced when he was very young. His mom treated him like a boyfriend. His girlfriend reported seeing his mother sit on his lap and stroke his hair. He's thirty five. He had not had sex with his girlfriend in six or eight months.

I knew some of this before the incident so if it seems I rushed to judgment yesterday it is only because so many things suddenly made much more sense in this new light. It is still possible he is innocent of everything. It depends on exactly what they found, I suppose, and they have a year long record of someone, using several different IP addresses which they can now connect securely to him, I believe, viewing a great deal of very disturbing things online. They read the titles and descriptions of all of them to my wife's friend. We had a large bust of a child pornography ring here last month, actual production of the stuff, and the police admitted that there were fifteen additional people being raided here yesterday. I believe he had also recently befriended a young autistic man of twenty four or so who has young children. The police asked if he he had had any contact with people with young children, and his girlfriend told them that he had, and who they were, so they could question them. In retrospect, I'm glad I didn't get closer to this guy. My cousin has young kids and they are over at our house a lot. Again, I'm not saying this man actually did anything to children himself or intended to. But I see a lot of data points that fit a certain class of patterns of human psychological illness here.

So that's about it. That's all I know at this point. My wife and I are glad that we can be there for her friend while she goes through this, it isn't over for her yet, not by a long shot. Her family owns the trailer park (no snickers, it's very nice) where she lives (in a three bedroom double wide that is as nice as my place, and why am I worried about class issues right now?) She may have to testify, that depends a lot on him, I imagine. We don't even know where he is being held. No local police were involved, it was all state and federal. He called and left a message for her, said not to believe anything they said, asked her to pray for him, and asked her to help bail him out. His bail is eighty thousand, so someone would have to some up with eight. There is no way in hell she is going to put up any money. Note that in his message, again he did not directly protest innocence, he said, "Don't believe them." I believe there is a high risk that if he did get out, he would kill himself, which is why I made the comment yesterday. I was empathizing with what I can only imagine a person in his apparent situation must be going through. That's one of my flaws, I can't really shut off my empathy. It makes it hard to be around people sometimes, or even watch certain kinds of movies or television, like the original British version of The Office took me a really long time to warm up to, I always felt too much empathy towards the character Michael Scott to laugh at him. But I'm babbling now, I guess I don't really have anything else to say at present.

Journal Journal: Automotive Security

According to the Center for Automotive Embedded Systems Security, there are serious security flaws in the existing technology. Not necessarily a big deal, for now, as they observe that the risks are low at the current time. Emphasis on "current". They also state that no crackers have been observed to use the required level of sophistication. Again, emphasis needs to be on "observed". Yes, it may well be a while before automotive networks reach the point where this is exploited in the wild (at least to any scale), but I would remind you that it took Microsoft from Windows 3.0 through to Windows XP Service Pack 2 to take security even remotely seriously. That's a long, long time. And Microsoft had nothing like the install-base of the car industry. Further, the qualifications required by most companies to be a system administrator were a good deal steeper than the requirements for a car mechanic, so systems administrators were likely far more familiar with the issues involved. Also, said systems administrators are far more accountable for security issues, since there are plenty of third-party tools that novice users can use to spot malicious software.

The first question is why this even matters. It doesn't affect anyone today. No, but it's guaranteed to affect at least some current Slashdot readers in their lifetime and, depending on how rapidly car networks develop, may affect a significant fraction surprisingly fast. Technology doesn't move at Stone Age speeds any more. Technology advances rapidly and you can't use obsolete notions of progress to determine what will happen next year or over the next decade.

The second question is what anyone could seriously do, even if it was an issue. Not too many Slashdotters own automotive companies. In fact, I doubt if ANY Slashdotters own automotive companies. Well, the validation tools are Open Source. MISRA has a fair few links to members and software packages. In fact, even if developers just developed an understanding of MISRA's C and C++ specifications it might be quite valuable as it would allow people to understand what is being done (if anything) to improve reliability and to understand how (if at all) this impacts security. You don't get reliability for free, there will be some compromises made elsewhere.

Journal Journal: Has anyone had problems with DB companies? What therapies work with bosses? 4

I've been having problems with Enterprise DB. This company maintains the Windows port of Postgres, but I have been finding their customer service.... less than satisfactory. This is the second time in, oh, 21 years that I've actually been infuriated by a company. However, to be entirely fair to the business and indeed the sales person, it is entirely possible this was a completely freak incident with no relationship to normal experience. There were all kinds of factors involved, so it's a messy situation all round, but the hard-sell aggressiveness and verbal abuse went way beyond what I have ever experienced from a professional organization in two DECADES. What I want to know from other Slashdotters is whether this is about on-par with the tales of meteorites landing on someone's sofa (which is my personal suspicion) or whether it's a more insidious issue. Please, please, please, do not take one incident as a general rule. I've not seen any article on Slashdot or LWN reporting wider issues with them, which you know perfectly well would have happened had there been a serious, widespread problem. Especially with all of the reporting on database issues over recent times and the search for alternatives to MySQL once leading developers defected and major forks arose.

This is, however, a major question. Like it or not, we need databases we can rely on and trust, which means that when they are backed by companies, we need the companies that back them to be honorable. (PostgreSQL itself isn't owned, so I trust the engine itself just fine. The development team is very impressive - and, yes, I do monitor the mailing lists.) Value-added only has any added value if it's valuable.

What is worse, from my perspective, is that my current boss is now treating it like this is how companies work when reselling Open Source products. His practical experience was being on the receiving end of all this. If we're to take advantage of the freedom (and bloody high quality) provided in the Open Source world, I need to deprogram him of the notion that they give hassle and sell grief. Does anyone have any experience doing this?

Journal Journal: Slashcode Follies 6

The codemonkeys of Slashdot have obviously been pounding randomly on their keyboards recently. Here's a thought, if you are going to hire monkeys to maintain your code, you should at least test it before deploying it to your live servers. This hasn't been Rob Malda's personal blog for years, it's a fricken' business. Do you Slashdot employees like your jobs? Do you want them to continue to exist? If so, perhaps you should start treating this like a business and not like a hobby. Quit breaking things.

Journal Journal: PayPal Donations... I'll be damned 1

So a while ago, I wrote a little web based e-book called Autocross To Win (inspired by Carrol Smith's "To Win" series.

You can see it at http://farnorthracing.com/autocross_secrets.html

I wrote it primarily because I wasted a shit-ton of money chasing my own tail and following "conventional wisdom" when it came to race car setup, and discovered a number of things that conventional wisdom got wrong.

It became more important to me just before I left for Afghanistan. I didn't want this information left locked inside my head where it would be lost if I got knocked on the head while in theatre. It seems silly I know, but I wanted to make sure that it wouldn't go for naught if I got killed.

Now I'm back - and I'm unemployed. I've been trying to go back to Afghanistan but there's no open slots and I'm having a lot of trouble prising one open. And it struck me that there's a lot of good info in ATW - enough that it probably makes a good book.

But I also do not regret the impulse that put it online for free. To pull it down so I could charge money for it... that seems dishonest. Information really does want to be free, even the information I wrote myself.

I put some ads on the site, but I'm not a high-exposure site. I'm deep, not broad, and I'm very highly specialized. The ads cover the bandwidth bill and little else.

So yesterday I figured I'd try a tactic that I've seen web cartoonists use - the PayPal "donate" button. I added one to the ATW base template. Small. Unobtrusive. No fanfare or hard sell. No promotion of this on any of the forums I use to announce site updates. Just added it quietly.

And 24 hours later, I have my first donation. Wow, I didn't think that would work.

I'm going to do up a little "thank you" certificate and email those out to donors.

Maybe this is how all content providers will get paid from now on...

Journal Journal: Freedom 5

I just had an interesting revelation regarding freedom. My mom came down with pancreatic cancer about a year ago, and I felt my personal sense of freedom curtailed. Sure, it was only curtailed by my own sense morality and obligation. but it was limited nonetheless. And I noticed, there is only so much freedom I am willing to give up. I was suddenly much more aware of, and resistant to, all the other limitations on my freedom like my marriage and my job and living in a society where I have to wear pants. Then my mom died, and I inherited a house and quite a bit of money. Now that my freedom is far less constrained by finances, or by dying single mother, only child dynamics, the minor impositions of job and marriage and pants obsessed society don't even register.

I've read that the sense of certainty is simply an emotion, a specific analog circuit that engages and drives our logical mind to come up with explanations. Now, through experience, I believe our sense of freedom is another emotional circuit. While in a strictly deterministic world individual freedom does not exist as such, the sense of personal freedom is a very real part of the chain of cause and effect.

(And thus, a personal conundrum is resolved, cognitive dissonance is decreased, and pants are worn.)

A petition calling for the return of perhaps the most important television show since The Great Egg Race is currently running but isn't exactly getting anywhere fast. It is vitally important that intellectually-stimulating shows be encouraged -- the consequence of failure (24 hours of Jersey Shore on all channels) is too horrible to contemplate. Unfortunately, as things stand, that's exactly what we are heading towards. Save your television and your mind before it's too late!
