Here’s some text.
I’m somewhat new to San Francisco and have only ridden the MUNI train once previous to today. I was completely unaware that you needed to keep the receipt after deposting $1.50 in quarters in the turnstile. I figured that since I just payed for admittance, that was all there was to it.
I get on the train and then all the sudden this dude starts checking tickets. I explained to him that I never got a ticket, I just payed and walked through the turnstile. He was nice very about it and told me that I should contest the ticket.
The rules of conduct are not posted anywhere visible. They just assume you’ve been riding the MUNI for years and should know what the hell is going on. The whole system of having someone deposit money in to a turnstile and then expecting them to grab the ticket/receipt is counter-intuitive.
The message that it sends is, “Hey, you just payed for entrance! Have fun!”, with nothing telling you how the system actually works.
The turnstile should NOT allow admittance until the ticket has been removed by the rider, or better yet, it should function similar to the BART or MTA, where you purchase your tickets beforehand.
Obviously, this would take some pretty big reworkings, so how about just giant signs saying “Don’t forget your ticket!”. That should cost what, around $2000?
Absolutely amazing. This person “drew” a self-portrait using a suitcase with a GPS device along with the help of DHL.
And my suspicions were correct… scroll down to the bottom of the page and you’ll see, in bright red text: This is fictional work. DHL did not transport the GPS at any time
Not to say that this has any sort of impact on the work itself…
Art is the trace, not the journey.

We had a bit of miscommunication over how to select some articles for our editor queues here at BleacherReport.
What we wanted was to select all articles that have not been edited by an admin or a trusted editor.
I, being in a hurry and thinking more about the Javascript that I was about to write instead of something as simple as a database selection, formated the query using:
(articles.admin_edited = false OR articles.admin_edited = true)
Our lead editor noticed that this wasn’t working as expected, and notified the development team.
I figured this was the perfect time to go back to a concept that I hadn’t really used much since 8th grade, truth tables!
I’m going to say that ‘p’ represents admin edited articles and that ‘q’ represents trusted edited articles.
Let’s go back to the original specifications. It was asking for all articles that have not been edited by admins or trusted editors.
NOT (edited by admin OR edited by trusted)
¬(p ∨ q)
I decided to construct the above truth table to find that one logical equivilence of ¬(p ∨ q) is ¬p ∧ ¬q.
In English, this would be: All articles that are have not been edited by an admin and have not been edited by a trusted editor.
Now, that doesn’t really sit too well in the brain, now does it? At least not as well as the first way of putting it, which is what everyone pretty much defaults to.
So, I found that I was selecting the exact opposite. The proper select statements should have been either:
(articles.admin_edited = false AND articles.trusted_edited = false)
or
!(articles.admin_edited = false OR articles.trusted_edited = false)
This is an example of a NOR operation.
What is interesting about the NOR (as well as the NAND) operation is that it can be used to construct all possible logical operations. In fact, the computer on board the Apollo 11 spacecraft was constructed intirely of NOR gates with only three inputs!
This continues today. The majority of logic gates found in microprocessors are composed of NOR and NAND gates.
Isn’t it ironic that the the logical operator that I was having issues with is the basis of all of the hardware running the machines our business is based on?
OR
Holy crap, I’m a nerd.

Is there no end to the number of ways oil culture is screwing us?

Uhm, correct me if I’m wrong…
The City of Portland Office of Transportation, which for some reason goes by PDOT, is primarily concerned with the types of transportation that use motorways. I could not find any reference to non-motor vehicular modes of movement within the literature of this group.
Based on this, it makes complete sense for the taxes that support this government agency to be based on the number of gallons sold rather than the price of gas. If gasoline prices would rise to the point where they are lowering the amount of vehicles on the roadways, then the upkeep costs would be reduced as well.
If the taxes collected were based on the total price of gasoline, then the PDOT would have more funds available to sustain the roads, in turn promoting transportation that was reliant on gasoline.
The only modifications of this tax should be based on the fact that the efficiency of internal combustion engines is increasing. In this case, the tax should be changed to reflect that automobiles are traveling more miles on a gallon of gasoline. Therefor, they would have a greater effect on the infrastructure that government provides for their functioning.
As it currently stands, the economics of the situation are sound.
Last night I threw the TV antennae out of the window of my sister’s apartment and now I can’t watch Lost.
