Journal Journal: I owe Bill Dog continuation, Prius Hack ideas 10

Bill's last set of answers, and my answers to his answers
 
>>1. The only reason to run the gas engine under 25 miles an hour [â Typical residential speed limit] should be for recharging and generating, period. EV mode only at low speed.

>And Toyota may have started out planning on along those lines, but may have gotten focus group research that indicated people preferred a little more acceleration.

Which is weird, because when you put the two electric motors working together, you have MORE acceleration than the gas engine alone. 104 HP vs 70 HP.

>>2. An expert mode should be available wherein "creep ahead at stop" is disabled

>Having switched to owning only manual transmission cars, I only miss that on a metered freeway onramp, that's uphill. I imagine it's added behavior when in electric-only mode, to simulate a slush box, so not sure how it could be universally defeatable. There's no "neutral" on those smug little cars?

There is, it just doesn't auto-engage. The default is creep ahead (and yes, it's electric- it is quite obvious that your gas engine has stopped and it's in stealth mode- which makes it even more dangerous for say, a pedestrian in the cross walk in front of you, no warning roar of the engine as the car speeds up to 8mph slowly).

>>3. Cruise control should also be able to be set by a numeric keypad, and should be able to handle values lower than 23.

>That's an awesome idea, rather than having to bring the car up to the desired speed manually. But I wouldn't be surprised if it's the government disallowing the latter.

It certainly gets them more speeding ticket revenue in 20mph and 15 mph zones. That, and thanks to the "delayed reaction" in the CAN of the prius, I can never seem to hit the correct speed. Always 1mph off, either above or below. And why does slowing down below 23 erase the register, forcing a manual reset, instead of disengaging alone?

>>4. Sport mode should be available that disengages the traction control and enables all three motors for acceleration (you can get the second half of this in a gen2 by angrily stomping on the accelerator, it takes a second to engage, but you suddenly go from 34 HP to 174 HP as the second electric and the gas motor kick in).

>Why would a Prius owner want this?

Ice, sand, and mud. Thanks to the traction control the way it is, and the standard modes, it is impossible to get more than 34hp to the wheels in the first second of travel; and in addition to that, if there is any wheelspin at all, that 34 goes to 0 hp real quick and a little light blinks on to tell you that your transmission is disengaged. A sport mode would enable both drag racing and off road abilities that the prius currently lacks.

>>5. Finer resolution than 5 minutes on the average MPG consumption graph.

>>6. Ability to download trip data onto an SD card.

>Likely never, directly. Companies want your personal info to go to "the cloud" first, so that they can mine it and monetize you further.

I'd even accept an upload to the cloud if I could get fine resolution consumption and the ability to diagnose my driving habits after the fact. The big change in driving a prius isn't so much the technology, it's the feedback given about your fuel consumption, and it occurs to me more feedback is better.

>>7. If gas tank 20% full and battery 20% full, hibernate mode on computer if accidentally left on and wheels are not moving. Right now if you tried to use a Gen2 prius as a backup house generator, you run the risk of bricking the system, unable to boot computer, unable to add more gas, must drag onto a flatbed and tow to Toyota to use their fancy charging system to bring the car back to life.

>I guess you're saying these cars have no under-hood starter battery like ICE vehicles, that's user-swappable with a replacement from any auto parts shop. And I guess neither can these cars be jump-started, simply by using another vehicle (with a battery of equal or greater cold cranking amps). Wow.

More of an in-the-trunk starter battery that is only good for booting the computer system. If you run out of gas *and* the high voltage battery goes totally flat the most you will be able to do is boot the computer, the high voltage battery is needed to spin M1 to be the starter motor (M1 does triple duty- it's a 34 HP electric motor that does the initial acceleration, serves as a generator, and also serves as the starter motor for the gas engine- and it runs off the high voltage battery; M2 is a 70 HP electric engine that can also double as a generator, and then E1 is the gas engine that can send power to the wheels, to M1, to M2, or to all three- quite a complex computerized transmission runs it all). So there would be good reason to provide a hibernate mode that would allow a Prius to be parked for more than three weeks.
I suspect that a plug-in conversion and/or a Gen4 plug in prius is the answer to that last problem- if you're feeding off the grid regularly, there's no need for the gas engine to generate power to begin with.

Journal Journal: gun garbage [long] 9

Someone kind of set me off at work on Friday. Gotta work on that. She was apparently reading something about an idea to arm teachers. Or more specifically, offer concealed carry licenses for the classroom. And indicated that she was appalled by the idea.

I said one of the beauties of concealed carry is that not everyone even has to have a gun, to still have the effect of discouraging bad people.

1) First it was the old "argument" that let a person have a gun and they'll turn into a dangerous lunatic. Teachers will be letting bullets fly all over the place, endangering the children and everyone around them.

I asked, should the police be allowed to carry guns? She apparently knew where I was going with that, and needed a minute on that one, so came back to what I had offered right before, and said well:
2) How is a teacher going to conceal it, and
3) How are they going to whip it out in time?

To the first, understand that only having it on their person is not essentially required. And in fact would be a bad idea, as it was seen recently in the news an older male teacher being overpowered by a single large student. I would suggest small gun safes, installed in the walls, in every classroom. And then the teachers having the key to it, among their other keys, on their person at all times.

But then a student or students could overpower the teacher and get the keys? Yes, but beyond the factor of not necessarily knowing which key is the one (only the teachers should know this, in addition to never giving out their key ring, even temporarily for something, to a student), this is where the "concealed" part comes in. I've just added a level of indirection to it. Student(s) still don't know if the gun safe in their classroom has a gun in it or not. Heck, put a gun lock on the gun so a bad guy student has to go through the exercise of finding which key works again; this is even more time for other students to exit the classroom during the altercation and seek help from other classrooms.

To the second, they are, and they aren't. If someone bursts into your classroom and starts shooting, they've simply got the element of surprise in their favor and you aren't going to stop them. It's about discouraging it from spilling over into other classrooms. It's not about some vain attempt to ensure that absolutely no one gets killed evar, it's about limiting the damage of these, albeit rare, incidents.

Adjoining classrooms, having heard shots fired somewhere near, would proceed to open their gun safes. Those teachers who've volunteered to have guns in their classroom safes and to respond to emergencies would take them and try to track down which classroom the incident was taking place in and end it. So why then a policy of everyone opening their safe in an emergency? I would have doing so trigger [unintentional pun] a special alarm throughout the school, so that even those who couldn't hear the shots fired would be given notice. Such as to prepare to defend their classrooms or to move their students to an armed classroom (the teachers should know who's part of the program and who's not).

(But then after a school shooting then the students (while they're at the school/in those grades, that is) will know who's armed and who isn't? True, but these are rare occurrences. And slight imperfections in any plan in general doesn't overcome its overall benefit.)

4) Then it was the old suggestion that more times than not the gun will be taken away and the victim will be victimized by their own weapon.

Well that's like the argument that we shouldn't fight back against terrorism, because it only angers the terrorists and causes more people to join them. You have to fight evil; you can't just refrain from trying to curtail violence by bad guys because of all the possible side effects. The alternative is ridiculous.

5) Finally, after having offered up this usual array of Left-wing criticisms, it's claimed that she only meant that her objection was that there was no mention of them getting proper training.

So now we're back to my prior posed line of questioning. I agreed that training should go along with the policy, if it's actually implemented (yeah, right; in today's America?!). But the police for example get training, and they still panic and empty their guns shooting up the wrong vehicle or into other houses. It's just ignoring human nature to expect all or most people to not freak out when they think their very lives are in danger. But that's not a reason to disarm the police, or the populace for that matter.

Which segues into my main point on this. A distinction between (mere) citizens, and "the authorities" (which the Left wants all (white) people to obey without question), is an artificial one when it comes to this. You're not imbued with some kind of magical extra-human powers when you're deputized. You're still just a person, susceptible to all the fears and failings of a human being.

So a recap and a filling out the remaining of what the Left would have us believe about people and guns:

* In general, no one should be allowed to have a gun except members of the government. Because only they can handle it, somehow.

* Unless you're a racist cop.

* And unless you're a member of military, really, because people only join the military because they want to kill people (and not at all instead because they want the government benefits).

* If you're a celebrity, then it's also okay if you own a gun.

* Even if you're one who vocally advocates for civilians not being allowed to have a gun.

* In general, "gun owner" = "gun nut".

* If you want a gun (aside from needing it for your job, or needing it because of the possibility of crazed fans or Right-wing detractors), you're a nut.

* Even if you don't start out a nut, having a gun will make you one, somehow.

* Defending yourself (and defenseless associates) against lethal force with lethal force only makes the situation worse. [For who?]

On a personal/full disclosure note, I don't own a gun, never have, maybe never will. I grew up (and probably because I've always lived in California) not knowing anyone personally who has guns, and still don't, except for my sis and her hubby who just got one recently. I shot BB guns *once*, in summer camp, I was never in the military or law enforcement or security, guns aren't in any way a part of my life, I may never own a gun in my life, but I want that right, along with all of the others in the Bill of Rights, in case I do someday wish to have one. (I don't need to wait until I personally want to exercise a right, to care about it.)

Journal Journal: Web Dev on the Mac 1

I've been working on a little side project. I would like to have an app where people can read updates that I send out. It seemed like a fun way to learn more about programming mobile apps and it's something I could actually use if I can get it to a decent state.
 
I'm keeping it simple. I decided the app would just be an rss feed reader. And that meant I need a feed. I want it to be very specific to my app so I decided the way to go would be to just create my own back end for creating the feed. I decided to use php and I wrote a simple set up using the codeigniter framework. That gave me a quick way to set up authorization and it was easy to tie in styling from bootstrap so that things can look decent without any effort.
 
I've been doing all the work at my office, on my desktop running Fedora. I have two nice big lcd monitors and developing on Linux is just so easy. I had the environment up and running in no time.
 
Then this week my son got sick. Nothing serious - but enough for him to stay home from school for a few days. I worked from home to keep an eye on him. I've been putting off getting my Macbook set up to do this kind of stuff but now I really needed to tackle it. Ugh - what a pain. The machine itself has grown on me. The hardware is decent and works pretty well. The software isn't horrible. But oh my word - when I want to do anything 'out of the ordinary' and by that I mean any kind of meaningful work with the system, it is pretty bad. I know lots of professional developers use Macs but I'm stunned at what a pain it is to do things that are trivially easy in Linux.
 
Getting Mysql installed and running with Apache was a lot more work. Getting PHP working the way I want took more time than it ever has before. Things are far from ideal even now, but I've got it to a point where it works.
 
And now I have my code in 3 places. So I'll be using github to keep code in sync between them. It's a little more of a challenge because I have the production environment set up a little differently than the dev environment. But not so differently that it is a huge deal. I have ssh access to my hosting environment (Bluehost) so that makes it pretty easy. - Oh and that is the one thing that saves the mac - having bash. If it didn't I'd have given up on it long ago.

It's rather sad that this is the best we have now. Granted, the other guy could dramatically improve his act by following all his comments with fart jokes, but the better act sucks too. Comparing these two is somewhat like comparing the kid who calls a random number on the phone and asks about their refrigerator to the kid who calls numbers he knows and recites Bart Simpson prank calls.

Journal Journal: Welcome back, SlashPot (thank you failure machine samzenpus) 39

I guess "failure machine" samzenpus really will post anything.

Now, before the Pro Pot Propaganda Pushers here start calling me a fascist, let me point out where my criticism is. This is about how samzenpus failed to even approach a useful summary of the article that the summary linked to - which I will point out is freely available to everyone. In particular, because failure machine couldn't be bothered to read the article, he missed:

Nevertheless, as previously stressed, our findings should not be interpreted that moderate alcohol consumption poses a higher risk to an individual and their close contacts than regular heroin use14. Much of the harm from drug use is not inherently related to consumption, but is heavily influenced by the environmental conditions of the drug use2, and this additional hazard is not included in a drug ranking based on (animal) toxicology.

The first major problem of the approach is the lack of toxicological dose-response data for all compounds except alcohol and tobacco. No human dose-response data are available; also no dose-response data in animals, only LD50 values are published. Furthermore, no chronic-toxicity data (long-term experiments) are available, which are usually used for such kinds of risk assessment. Therefore, we can assess only in regards to mortality but not carcinogenicity or other long-term effects. The absence of such data is specifically relevant for compounds with low acute toxicity (such as cannabis), the risk of which may therefore be underestimated.

In other words, the study was looking to see how much of a substance was required to kill you immediately. They mentioned very few substances have known limits for that. They also went on to mention that cannabis in particular is not studied much from a toxicology standpoint when compared to other drugs:

The second major problem is the uncertainty in data about individual and population-wide exposure due to the illegal markets. There is a scarcity of epidemiological studies of cannabis use by comparison with epidemiological studies of alcohol and tobacco use

Indeed, I agree with their closing remark:

Currently, the MOE results point to risk management prioritization towards alcohol and tobacco rather than illicit drugs. The high MOE values of cannabis, which are in a low-risk range, suggest a strict legal regulatory approach rather than the current prohibition approach.

Not that the propagandists here on slashdot would bother to read that far.

Journal Journal: fun with CSS 3 I guess 2

So go to www.google.com (I just type in the middle part and use the Ctrl-Enter thingie, a lot), presumably in a modern browser, and type in "askew" without hitting Enter.

It probably only works in the mode where upon typing the first character into their home page it automatically jumps to the search box being in the upper left and intermediate results being displayed as you type, so might require JavaScript being enabled.

You can restore things by backspacing all the way and then begin typing say "askance".

Anyone come across any others? I see that "skew" is one of the keywords in the 2D transforms of the CSS 3 spec, but that word doesn't affect Google, as neither do some of the others.

p.s. On a partly unrelated note, what's with Google removing my dang commas. Paste in "275,908.952 watts" and then type " to hor", and it says "Showing results for 275 908.952 watts to horsepower", and only one document in the results listing. Click on the pop-up suggestion of "horsepower" and... you don't get your conversion. Go back and put the damn comma back and you'll get it. (But then notice in the conversion output that it lists the wattage without the comma!)

Journal Journal: Might explain some of the behavior here 23

I have quoted before my old friend Theodore Dalrymple on the purposes of lies in totalitarian societies:

In my study of communist societies, I came to the conclusion that the purpose of communist propaganda was not to persuade or convince, nor to inform, but to humiliate; and therefore, the less it corresponded to reality the better. When people are forced to remain silent when they are being told the most obvious lies, or even worse when they are forced to repeat the lies themselves, they lose once and for all their sense of probity. To assent to obvious lies is to co-operate with evil, and in some small way to become evil oneself. One's standing to resist anything is thus eroded, and even destroyed. A society of emasculated liars is easy to control.

This has a ring of truth to it with respect to Slashdot. I've been on the receiving end of repeated accusations used like bludgeons to the point there are some people on here to whom I just ain't got jack to say beyond: "Lord bless your heart".
Which is not to whine about it. This is Slashdot; let the incontinent go elsewhere.
Rather, I'm yawning.
