Enough. The question is crap, but if he had looked at lesson 10.3 it should have been clear what was expected.

It's clear to those of use who have taken stats courses but this is a kid learning addition. His 3 time jeopardy champ father is the rock star.

Secondly "do no harm" comes from the history of medicine, not education. There are many lessons that come from mistakes, deception, etc. In this case his son learned to think critically and to question authority.

If you keep in mind the context of the question (2nd grade homework) then you'd realize that the student wouldn't be expected to come up with the more complicated correct answer of 27. It's entirely possible the teacher thought you (the parent) helped too much and her comment was a snarky remark to you.

Personally I think the teacher missed the boat. Her comment used a poor choice of words. She should have marked it correct and then talked to your child about what answer the lesson was looking for.

Yo WR, question about Magic Lantern. Do they have a mod to turn a DSLR into a slit camera yet? That would be a heck of a good way to setup a fairly reasonable finish line system.

Based on the question asked, 27 is indeed the correct answer. And here they are:

R= Red, G= Green, O=Gold

Exactly.

You my friend have too much time on your hands...

There is a slit-scan feature, but I'm not entirely sure how it works. I believe it's only 60fps though, so that wont' be any more information than regular HD video, although I believe the output could work like a finish line camera, which would make analysis much easier.

Here's the description (search for slit-scan). You have to post-process the output, and I haven't gone to the trouble of trying it out yet.

well the big batch of 20nm Ag that I spent two days preparing, synthesizing, and finally QC'ing turns out to have a bi-modal size distribution. frak

this happens frequently with 20's, but it still pisses me off. time to do the same thing over again now.

Houston, we have data!

i may have just yelled that in the lab and received some weird looks.

I know the feeling. Enjoy!

I can only imagine what it's like on the programing side...

Our programer/electronics/robotics/instrumentation/IT/everythingelse guy once described his algorithm as "purring like a kitten".

or maybe that was you.


data is good. I have lots to play with, and the values appear to be where I want them to be upon cursory glance

mollusk

True.

I was severely beaten across the back repeatedly with a wooden pointer (I'm talking at least 20 times) by a nun when I was in 1st grade. Most of them were hard enough to break skin. My back of my "school uniform" short sleeved white shirt was soaked in blood when I got home.

The Missus rarely wants computer type stuff. She decided she wanted an iPad. We went out and got it the next day. 64 GB no less - I figured that we won't miss $100 in a year or two but if she jams in 31.9 GB of pictures of Junior on the thing she'd miss the 32GB of extra memory.

Uber dork topic -- Ham radio. Anybody ever get into it? I'm reading up on it and the whole radio wave propagation, transmission, reception, modulation / demodulation is pretty fascinating stuff. Turning into an archaic hobby with the interwebs to a degree, but radio theory is fascinating. It's actually really pertinent too given how much data is transmitted via radio now. The voice aspect and connection to the remote world is what the interwebs has pretty much made obsolete.

I'm thinking of getting licensed and trying to make connections to far off places with low power equipment -- 5 to 20 watts output.

My grandfather was a wireless pioneer, W2ZI. He had what was the largest private antique wireless equipment museum in the country. It included the smallest working telegraph key ever made, as well as the key from the Titanic. After his passing all of it was donated to a smaller museum, making that museum the biggest antique wireless museum in the world. We called him Sparky. He had all sorts of cool stuff for kids to get in trouble with. Spark wheel transmitters, vacuum tubes from the transmitters atop the Empire State building, stuff like that. I studied for my license but never took the test.

jwible

That's really cool.

This stuff probably looks familiar then -- https://www.newsm.org/Wireless/wireless.html

I have a key sitting on my desk that my dad picked up in Peru. I always thought it wasn't much more than a neat paperweight, but the more I read the more I realize these things are pieces of history.

shovelhd

Yep. That's the place where his stuff ended up. He is mentioned in the list.

That's a lotta pictures.

I shot 16GB of still pictures in two hours last night.

ridethecliche

Wow...

My card is only 8 gb. And I've never filled it up. My xsi doesn't really go crazy with the picture quality though...

I almost want to buy a t2i/t3i before i leave on my travels.

waterrockets 

I'd recommend glass before body, depending on what you have.

FWIW: that was ~650 images. I shot another 550 the night before. These were all action shots for a swim team fundraiser (over $1000 raised).

ridethecliche

I have the stock cannon lens and a zoom lens. The body is an canon xsi: https://www.amazon.com/Canon-Digital-.../dp/B0012YA85A

waterrockets 

well, just like bike racing: figure out what your limiters are with the things you're photographing, and learn skills and buy stuff to eliminate them. That XSI is like a CAAD9. T2i is great, but it's really just a newer CAAD9. XSI is clearly a capable body...

ridethecliche

Agreed.

I would like some video capability though. Lots of fun to be had with that. My pocket camera is DYING. Maybe I should try to revive it for this trip. Dropping a DSLR while taking video on motorcycle would suck.

I think that there's an issue with the lens or the sensor. I get this weird bright red pixel in every picture in about the same place and it's not my monitor.

I need to check and see if it happens with both lenses (sensor) or just one (lens). The lens addition is probably the smart thing to do. I could have some fun with a wide angle and prime lens.

I've had some good shots with the camera as well.

fark, my ethernet's MAC address was just put on the university's s*** list for apparently trying to connect to a known bot site

the university doesn't actually know what that IP address is...
