Colorado Sued By Neighboring States Over Legal Pot

Streetlight Like, Nebraska and Oklahoma don't have illegal MJ (434 comments)

One thing legalizing marijuana may do, besides producing some tax revenue, is allow for reasonable regulation of it's distribution. Nebraska and Oklahoma authorities are whistling past the graveyard if they think they don't have any marijuana in their states and any there must have come from Colorado. I would also guess that the MJ dealers in those two states are not getting it from legal sources in Colorado. There are likely cheaper sources from elsewhere including home grown stuff. I haven't heard whether legal marijuana sales in Colorado has eliminated illegal sales, but it has likely reduced the cost of police searching for it and housing offenders. Police and jailers have better things to do. By the way, I live in Colorado and have never used marijuana.

In Iowa, a Phone App Could Serve As Driver's License

Streetlight Cops might also be interested in where you've been (207 comments)

The comments here seem to focus on the situation that by giving your unlocked phone to a cop so he/she can see the driver's license will allow the cop to get everything on the phone. One other purpose may be to see where you've been. This may occur if the Driver's License app makes use of the GPS system on the phone so that it records your itinerary and your speed. Could you then become a suspect in a crime because you were someplace where a crime was committed even if you were totally innocent? You might also get a speeding ticket for speeding a long time before the cop stopped you or could even have measured your speed.

Man Caught Trying To Sell Plans For New Aircraft Carrier

Streetlight Re:What in the hell was he thinking? (388 comments)

Or Bolivia.

An Air Force officer told me that an Air Force Academy cadet was once asked by a US civilian what service he was in. His response was that he was in the Bolivian Navy. The AFA uniforms are blue, slightly different in blue from that of US air force commissioned officers' uniforms with different emblems, etc.

UK Announces 'Google Tax'

Streetlight Re:Why not abolish corporate taxes entirely? (602 comments)

I keep hearing this suggestion but have not heard how those taxes on the shareholders would be taxed. If you own the stock of a company that pays no dividend you won't pay any tax even if the stock price increases. Under today's tax law taxes aren't levied on the increase in stock equity unless the stock is sold. And then the tax depends on how long one owns the stock and the total income of the seller so it's either 15% or 20% for long term holds. I also haven't heard anyone propose taxing the change in equity value of companys' shares held by individuals. If stock prices decrease then would shareholders should get credit for that decrease? Furthermore, the taxes produced could be very volatile as the willingness of stockholders to sell or buy stock varies. One thing government at all levels need is certainty in the size of annual tax revenue to pay for required services. One way taxes might be levied on owners of companies is to distribute all after expenses revenues to shareholders and then tax the shareholders. Companies are able to manipulate their books so there are no after expenses profits including moving profits overseas so there may never be any taxes paid directly or indirectly by companies.

I want to hear how shareholders in companies would pay taxes corporate taxes.

FBI Seizes Los Angeles Schools' iPad Documents

Streetlight Re:$1500 per ipad!? (229 comments)

I don't think it's even that simple. iPads have some kind of life span and will need replacement. When they're new there shouldn't be too much need to replace them but some will get broken screens and other problems associated with age and use. I wonder what the budget is for repair, maintenance and replacement. And as these iPads are in the system longer this cost is sure to increase annually. It may mean that after some number of years (five?) 100% of them will have been replaced. That initial $1 billion will become another $1 billion plus the repair bill. With 650,000 out in the field there will be a lot of repair techs either in a central location or in a shop in each school. All this will cost a bundle well beyond the initial purchase price.

FBI Seizes Los Angeles Schools' iPad Documents

Streetlight How are these iPads connected? (229 comments)

Perhaps I missed it, but I didn't find out how these iPads were connected to the Internet or even if they are connected. Do they use WiFi as well as Wireless telephony or just WiFi? If the latter, though most folks have WiFi at home, some do not. So do the students need to be near a hot spot to get school work done or is Internet connection unnecessary for educational use? If the iPads have Wireless connection then the cost of the contract with telephony carrier is an extra cost and who pays for the use beyond data caps? The articles indicate that the location of the iPads can be monitored by school district but I assume they can be turned off. In any event this seems to be a complete violation of the students' privacy.

Complex Life May Be Possible In Only 10% of All Galaxies

Streetlight Re:Light takes a long time to get here (307 comments)

In some sense it doesn't actually matter. If light traveled a billion years to get here, then any life that's happening "now" (for a sane definition of now) won't be observable by us for another billion years.

I suppose being able to observe the life is important for us but I assumed these guys concluded life was impossible in these galaxies. Just because we can't now or ever observe life there doesn't mean it isn't there.

Complex Life May Be Possible In Only 10% of All Galaxies

Streetlight Light takes a long time to get here (307 comments)

Most of the galaxies are likely to be so far away that the light - including gamma rays which are made up of high energy photons - has been in transit for billions of years. What's the situation now in those billions of gamma ray emitting galaxies we are now observing in the intervening years since the light was produced? They may have settled down making life possible.

Germans Can Get Free Heating From the Cloud

Streetlight Re:Great in the winter .. (148 comments)

Heat can be used to run air conditioners too if the temperature of the heat is high enough. Connect the heat output to a Sterling engine connected to a compressor or pumps for evaporative AC. This waste heat might also supplement the heat source for water heaters. I assume buildings in Germany have restrooms where folks can wash their hands. Some may even have showers.

The Students Who Feel They Have the Right To Cheat

Streetlight Re:Worthless degrees (438 comments)

This sounds pretty good. Making a plot of data that probably fits a linear model, say from chemistry or physics, is a good start. Then plotting the data on graph paper and eye-balling a straight line and using a triangle to get the slope and intercept will give students the concepts they need when they get to linear regression, on to nonlinear curve fitting and from multivariable analysis and using derivatives to find the function for the tangent at any point on a curve. Hopefully beginning students do the simple linear stuff by hand before they get to use and perhaps program more complex functions on a computer. Programming linear least squares is pretty easy but if students have done this by hand they'll really understand what it gives them from those early "by hand" exercises.

The Students Who Feel They Have the Right To Cheat

Streetlight Re:Worthless degrees (438 comments)

Two comments that support what you say:

1. One of my colleagues went to one of those teacher-parent conferences for his fifth grade child and asked when fractions would be taught. The teacher's response was they don't teach fractions because they're not used anymore. I think of that every time I take out a ruler or tape measure graduated in fraction of inches. My guess is that fifth grade teachers don't know enough to teach the manipulation of fractons.

2. Talked to a high school math teacher and he said that the math in first year algebra was basically grade five arithmetic. And they teach "calculus" in high school! I'm not sure what a high school calculus course must teach but I'm guessing not much. Elementary school students aren't prepared for high school. Do you expect HS grads to be prepared for college in the USA?

Rite Aid and CVS Block Apple Pay and Google Wallet

Streetlight Has anyone read the debit card TOS? (558 comments)

I have. Very interesting. One "feature" of debit cards is that if you use them at a cash machine and you don't get what you ask for, too bad, you lose. Now, if you get more than you ask for the financial institution will be all over you. And of course, as pointed out by many posters, there is protection against fraud for credit cards but not debit cards, at least in the USA. These are the reasons our family does not use a debit card.

One possibility credit card issuers could implement is to deny retailers the ability to accept their credit and debit cards unless they allowed the use of credit card electronic systems for their cards such as Apple Pay or Google Wallet. It might hurt the issuers for a while but the retailers more. Returning to cash and paper checks would impose enormous overhead to retailers reconciling mounds of cash and paper checks. Large retail stores will need fork lifts to move all that paper around.

The thing that makes Apple Pay so intriguing is that each transaction produces and transmits a unique code for each purchase that does not include the credit card number. I'm assuming the code is encrypted, but even if it's not, that code will not be used again so if it's intercepted it's useless to the thief. Not sure if the Google system uses the same process, but it would be easy for them to adopt it.

Will Fiber-To-the-Home Create a New Digital Divide?

Streetlight All rural residents need High Speed Internet (291 comments)

What speeds are really needed? I'd guess it depends on what a household uses Internet for and how many folks in the house will use it simultaneously. It seems to me we need to make it a national priority to get some kind of reasonable Internet speed in rural areas. Whether some areas have fiber to the home or some other technology that gives symmetrical Gigabit per second, in many areas dial up is the only thing available. Of course satellite or using a cell phone as a hot spot are possible but high cost and limited bandwidth aren't necessarily good choices. No video telephony or video streaming available there with dial up. Fifteen or 25 Megabits per second would bring rural folks pretty much up to date. My wife has cousins in rural Iowa about three miles outside a small town with those kinds of speeds from the local cable company but can only get 750 kilobits per second and 1.5 Megabits per second via DSL. Their parents live about half a mile down the same road and can only get dial up. Of course web pages now are filled with large images and it must be more than painful to load a single such page. My point is even if Gbps is made available in some areas a much more pressing need is to get reasonable responsive Internet speed to rural areas. Might be a good idea to go ahead and do it with fiber and skip coax.

Apple Doesn't Design For Yesterday

Streetlight Apple dumbs down "tomorrow" software (370 comments)

I didn't read any comments here about the common situation when Apple removes features from its "yesterday" software in new versions of its "tomorrow" software then scrambles to restore some of those features because of user complaints.

I'm not a Mac user so I don't know if it's possible, but it would be good if Apple made it easy for users to select an OS font best suited to their needs. If one has an older 21 inch iMac and maybe poor eyesight, then maybe some other font, neither Lucida nor Helvetica, would be better for them. Apple might even go so far as to make suggestions for folks with a visual handicap like macular degeneration, glaucoma or something else. Heck, Firefox on Windows allows font choice, though it's an app.
