Businesses: Use Nextdoor for free advertising

Nextdoor is a social media platform for people living in your neighborhood and nearby neighborhoods. Their terms and conditions (also see below) block businesses from joining but they don't appear to be enforcing this. A business in my neighborhood has now posted for the third time. I reported them to Nextdoor the first two times for violating the guidelines but apparently Nextdoor doesn't care, just like they didn't care about the unlicensed car dealer selling cars on Nextdoor. The third time I got a post from the business, I just "Muted" them so I won't see their posts any more (and I "Muted" the unlicensed car dealer as well).

So, until Nextdoor gets its act together, it can be used by your business for free advertising. Don't post too frequently, though, or people like me will get upset with you.

This Norwood (Ohio) Middle School Choir fundraiser has upset me

Thursday, September 3, the teachers and parents connected with the Norwood (Ohio) Middle School Choir made me feel bad and I don’t like it.

A student, whom I don’t know, knocked on my door and asked for $15 to buy a cup as a fundraiser for the Middle School Choir. But he wanted the $15 now for a cup to be delivered later. This put me in a bad position: If my cup didn’t show up, how would I find him again? I really didn’t want to ask him his name and address as that didn’t seem appropriate. So I explained to him that I wouldn’t pay without a cup and that wasn’t an option for him. I had to say, “Sorry” and he went on to the next person. I noticed that he hadn’t sold any cups. After he left, I felt terrible for turning him down, especially if he lives just down the street from me.

But it irritates me that the teachers and parents created this situation in the first place. When the Norwood Marching Band went door to door, they often went in uniform and in groups of three or four. There was an adult nearby who could vouch for them. I had no problem giving them $20 (which helped with their band camp fees). (Full disclosure: My son was in the band and I was a band parent.)

I know that learning how to sell and dealing with the inevitable rejection is a good learning experience, but this goes too far.

If I gave this student $15, how much would go to the choir? $3? $4? I’ll make the Choir a deal: If a teacher or parent contacts me by Friday, September 11, I’ll write a check for $15 for the Choir and they don’t have to provide me a with a cup. If there is a contest to see who sells the most cups, I’ll try to identify the student so he gets credit for a cup sold. I'll update this post next weekend with the outcome of this.

Update September 20: It's been over two weeks since I made this post and I didn't hear anything from the Middle School Choir about their fundraiser.

(Note: I posted this on Nextdoor for the Norwood neighborhood (my mistake; just one of three Norwood neighborhoods) about 12:45 a.m. and only got one "Thank" through 6 p.m. I'm thinking that this isn't resonating with anyone. I've deleted that post.)

"I'm special and I don't have to obey the law"

Eight "protestors" were arrested in Downtown Cincinnati last night. Yes, you can peacefully protest but when you try to use the cover of the protest to break the law, you may get arrested. And if you mess with the police trying to arrest someone, you will definitely get arrested. You will get no sympathy from me.

What I'm seeing today is a segment of the population, African American and White American but not Hispanic (as far as I can recall), who think they're special and that laws don't apply to them. Throw their fast-food bag out the car window? Sure, why should they care? Run a stop sign? No accident, no foul! Drive around with a broken tail pipe dragging on the ground? Man, where's the problem in that? None until it breaks off and ends up in someone else's radiator!

And then they get all indignant when a cop pulls them over. They're like, go get that drug dealer instead of me 'cause I'm special. Well, where I live here in Norwood, Ohio, the cops go for the drug dealers, too. As long as some people believe they can ignore the laws of society, we're going to have problems.

Background: Earlier this week, University of Cincinnati police officer Ray Tensing was indicted by a grand jury for murder following a traffic stop where he shot an unarmed driver and killed him. This protest, which started peacefully but appeared to be turning violent when the arrests occurred, was in response to the shooting. The family of the victim expressed their displeasure that the event was turning violent and disassociated themselves with the march after the vigil. 

The McKinney Pool Party Fracas — The rest of the story (Guest blog)

A guest blog by Daniel Artz

Where is Paul Harvey when we REALLY need an honest journalist to tell "the rest of the story?" Nowhere to be found among modern "journalists!"

I keep reading the stories and viewing the videos of the McKinney Pool Party Fracas that is threatening to become the North Texas version of Ferguson or Baltimore, with Black teens now staging protests both at the residential subdivision where the fighting/mob scene started, and at the McKinney Police Department, calling for the firing (or worse) of the police officer shown on video kneeling on the back of a Black teenage girl in order to subdue her.

BUT there are almost NO media sources which tell the whole story; it is in their interest to keep feeding the race frenzy.

Here is a brief synopsis of the genesis of the event. This all happened at Craig Ranch, a majority white but broadly integrated neighborhood in McKinney — there are hundreds of Black residents of Craig Ranch, including Tatyana Rhodes, a 20-year old self-styled "Party Organizer" who lives with her mother at Craig Ranch. Craig Ranch has a public park adjacent to a private pool club which is owned and operated by the Home Owners' Association. While the Park is open to the public, the private pool area is NOT — it is open to residents of the neighborhood, and admission is by ID only. Residents may arrange with the HOA to host a private pool party, limited to 20 guests, but may NOT exclude residents from the pool area, and must pay a fee and make advance arrangements to host such a pool party.

Several days, maybe a week or more, before June 5, Tatyana Rhodes was advertising through Social Media — on Facebook, on Twitter, through Instagram — a "Cookout and Pool Party" at the public park in Craig Ranch. She had hired a DJ, arranged for tables, power for the Sound System, etc., BUT SHE MADE NO ARRANGEMENTS WITH THE HOA FOR ANY POOL PARTY AT THE PRIVATE POOL AREA.

The DJ set up and started playing in the mid-afternoon, and a large crowd of teens, mostly Black, many residents of Craig Ranch but also many non-residents from outside the neighborhood, showed up for the party; the estimates I have seen are 200 or more. At the same time, there were residents of Craig Ranch, including families with children, using the pool club. There were complaints about the music — loud, mostly Rap and Hip-Hop, many songs with very vulgar lyrics (a lot of F-bombs) that bothered many of the parents who had taken their children for a swim. When the party-goers who were not residents of Craig Ranch were denied entry to the pool, many started climbing over the chain link fence to get into the pool. A private security guard at the pool club tried to stop several, and was assaulted by a group of pool-area trespassers. More and more party-goers invaded the private pool area, forcing out residents who were rightfully in the pool area, assaulting a white Craig Ranch mother who was at the pool with her 3 children, and the police were called.

One officer showed up, the party crowd was unruly and refused to comply with police demands to leave the pool area. Back up was requested, and eventually nine officers in total showed up. There were fights between party-goers and local residents, a large crowd of unruly teens (mostly Black), and most were refusing to comply with police demands. That 10-second video of the police officer kneeling on the back of that Black teen-aged girl does NOT show what happened beforehand, when the girl was defying police demands, confronting the police, shouting epithets, etc., nor does it show how she responded with violence and assaulting the officer when the policeman tried less intrusive methods of restraining her.

This is not a race thing — it's a culture thing. The culture of the ghetto, where loud vulgar language is the accepted method of communication, where respect for property and the rights of others is considered "uncool," where physical assault is an acceptable response for any real or imagined offense, and where the only imperative is to do what you want, regardless of its impact on others. So now it's going to turn into a racial demand for "justice." Well, real justice would mean arresting every last one of the teens who thought it was a good idea to jump the fence into a private pool area they had no right to be in and charge them with criminal trespass. Real justice would mean the HOA sues Tatyana Rhodes for making an offer of a "Pool Party" when she had no right to open up the pool to party-goers, and putting a lien on her mother's house in Craig Ranch for the penalties assessed. Real justice would involve charging that little teen-aged brat who had to be subdued by the police with resisting arrest and assault of a police officer. Then lock all of the agitators and rioters up for a long, long time. But I'm pretty sure that is NOT what the current protestors believe is "justice."

Reasoned debate is impossible without a common understanding of terms. So long as the race baiters think that "justice" means that a raucous group of ill-mannered and bad-tempered teens should be allowed to run free, trampling on the rights of others, there will be a great many people opposing that particular brand of "justice."

Air-powered cars? Not energy efficient enough

Three years after this post was published, I published an update here.

The most recent version of an air-powered car, first introduced by Guy Nègre in 1991, was featured on Shark Tank recently. Robert Herjavec is willing to invest $5 million into Zero Pollution Motors provided that they negotiate a North American license from Guy's company, Motor Development International. Currently, ZPM only has a license for Hawaii. Autoweek covered the story here.

Don't expect to see these cars on the road any time soon. Guy has been flogging this idea for over 20 years now with only prototypes to show for it. In 2007, he announced that Tata Motors had licensed the technology and would manufacture cars in India but a visit to Tata Motors' Web site shows no mention of air-powered cars. To my knowledge, Tata has not sold a single air-powered car.

Most people see the appeal of the concept. Where is the problem? It's in compressing the air for the car. Compressing air produces heat, which is typically lost, reducing efficiency. On the flip side, in the car, expanding the air absorbs heat which means the air needs to be heated, reducing efficiency. One way around this is to capture the heat and store it in a battery, using that energy to heat the air when it is used in the car. The end result is that an air-powered car is not sufficiently energy efficient to be practical.

I could see using air power in situations where energy efficiency is not a factor but convenience or access to compressed air is. For example, in an electrical power plant, the waste heat from the boilers could be used to compress the air, reducing the overall energy cost.

Part of the Shark Tank pitch was the concept of using "turnkey micro-production factories" to build the cars locally. With the car already being impractical, saddling it with an unrealistic manufacturing model will surely doom it. Just as Tesla has one manufacturing plant, only one manufacturing plant is needed to serve North America.

One final point: Neither Ethan Tucker or Pat Boone, the presenters on Shark Tank, appear to have any experience building or selling cars. Ethan, at least, is listed on the management page of ZPM.

I wish Mr. Nègre the best, but the physics are against him.

Amtrak crash in Philadelphia: A possible scenario

Thanks to reporting by the New York Times in this story, I have put together a possible scenario of the events leading up to the crash of Train 188:

1. The train leaves the North Philadelphia station and accelerates at maximum power to a planned 80 mph.

2. A rock strikes the train, damaging the windshield.

3. At some point, the engineer is supposed to take the throttle to idle and then apply the brakes to reduce the speed to 50 mph for the curve.

4. However, the engineer is distracted by the rock striking the windshield and doesn't start braking at the correct time.

5. Still accelerating at maximum power, the train continues past 80 mph to 106 mph.

6. The engineer regains concentration, realizes the train is going too fast, and applies the emergency brake.

7. But it's too late. The train tries to go around the curve at 104 mph, derails and crashes.

A Septa and an Acela train were also hit by rocks about the same time. Note that the engineer in the Septa train that was hit was shaken up enough by the incident that he couldn't continue driving the train.

The rock throwing has continued for many years. It's one of those things that the authorities don't worry about until someone dies. With this accident, eight people have died. The problem will now be fixed.

Computer camps for third graders

Recently, I got a call from a mother whose son wants to learn about computer programming. His school offers classes but they don't start until the fifth grade and they won't make an exception for her son who will be a third grader in the fall (seven years old). I found two summer day camps in the Cincinnati, Ohio area that have camps for third graders. (Note: The summer camp folks look at the grade your child will be in in the fall.)

I don't know much about these camps and this is not a specific recommendation. The main reason I'm posting this is to reassure parents that seven years old is not too early to begin learning about computers, whether it's developing games or writing programs.

One set of camps are offered by Classroom Antics. The camps range from Junior Video Game Design (ages 7 to 9) to Stop Motion Animation (ages 9 to 13).

Another place for a variety of scientific camps, including programming camps, is CINSAM at Northern Kentucky University.

Drake Planetarium also has camps that involve concepts related to programming. Once you display the page, click on "2015 Summer Camps" for more information.

There may be more camps that I'm not aware of. If you are connected with a summer computer camp, drop me a line and I will update this post.
