Comment I'm curious, how old are you? (Score 1) 203

The entire Y2K problem was from tens of thousands of programmers arbitrarily taking short cuts in their programming

I suspect you're relatively young as there were valid reasons to only store 2 digits for the year.

The problem started because on both mainframe computers and later personal computers, storage was expensive, from as low as $10 per kilobyte, to in many cases as much as or even more than US$100 per kilobyte. It was therefore very important for programmers to reduce usage. Since programs could simply prefix "19" to the year of a date, most programs internally used, or stored on disc or tape, data files where the date format was six digits, in the form MMDDYY, MM as two digits for the month, DD as two digits for the day, and YY as two digits for the year. As space on disc and tape was also expensive, this also saved money by reducing the size of stored data files and data bases.

And early then that you had to deal with punchcards, which could only store 80 characters per card. Punch cards were still in use when I went to college at Del Mar in Corpus Christi in 1984. While my incoming class was the first to no longer use them as part of our curriculum, the older students still used them. Everybody also used them during the registration process - pick up the card with your name on it at the entrance, walk around to the tables set up for each department and get a punch card for the class you wanted (if they were out of cards the class was full), then turn in the stack of cards to complete your registration.

Comment Keynote's pretty slick (Score 4, Interesting) 65

I use Keynote to give my Atari 2600 Homebrew presentation. To give the presentation I use both my iPhone and iPad. The iPhone plugs into the projector (after turning on Do Not Disturb, of course!). After launching Keynote on both devices I then use the Keynote Remote option from the iPad to connect to the iPhone (via bluetooth or wifi). The larger screen on the iPad makes it easy to see the slide side-by-side with my presenter notes, plus I'm free to walk around the stage without worrying about tripping over wires. There's also a virtual laser pointer and colored marker set that lets you point out things and draw on the slides during the presentation.

Comment Re: Try an Antenna (Score 1) 143

Yeah, there's a lot channels in Spanish, others in Vietnamese, Chinese, Farsi, etc. as well as the religious channels (those are super pixelated - they appear to be more worried about quantity rather than quality).

Out of the 129 channels there's probably about 20 of them I regularly watch(rather like getting hundreds of channels via DirecTV, but only regularly watching a few dozen - of course, I'm no longer paying for the channels I don't watch!). The High Def channels (ABC, NBC, PBS, KUBE, ION, etc) all look significantly better than they did on DirecTV. Likewise the Standard Def subchannels that I do watch look better (though not significantly) than comparable SD channels I used to watch on DirecTV.

The SD channels I watch are: This TV, Heroes & Icons, Laff(comedies), Movies!, Decades, Buzzr(game shows), Antenna TV, Comet TV(sci fi), The Works (though this network was dissolved last month and has been replaced by Charge! and I've not yet watched anything on it), MeTV, Get TV, and Grit.

Comment Saving $1500 a year's pretty significant to me (Score 1) 143

From the Looking back entry of my DVR Project blog series.

savings would be what I used to pay DirecTV ($146 a month) less purchasing shows à la cart - buying seasons via Amazon, iTunes, and physical media (Blu-ray & DVD sets).
I ended up saving $4575 over the past three years, for an average savings of $1525 per year!


Comment iPic Theaters are slick (Score 1) 213

Over the holidays I took family to the iPic Theater here in Houston for a screening of Rogue One. They have some really innovative seating pods - pairs of recliners share a table, and have a short sound proofing wall wrapped around them to help cut down on noise from other patrons.

I posted some photos of them at the end of this blog entry - Two million pounds of ice on a subtropical island!

Comment Re:Come on guys, isn't this a bit rediculous? (Score 2) 76

There is a major difference:

  • On color laser printers each C, Y, M or K dot is either either ON or OFF
  • On HDR display a single pixel can display any of 0-1073741823 colors. (Might also be 0-68719476735, the article doesn't specify which HDR spec the display is using, which is either 10-bits or 12-bits per RGB value)

As such, significantly more printed dots are required to get the same effective range as a single display pixel.

Legacy Port

A legacy port is a computer port or connector that is considered by some to be fully or partially superseded.

On the iPhone the 3.5mm headphone jack has been fully superseded by lightning and wireless. As such, legacy is the appropriate term to use in a discussion about iPhones and analog headphone jacks.

Congratulations! You just disproved the theory that Americans (and especially us Texans) are the most arrogant people on Earth!

Talk about misinformed. We didn't "find it 20 years later". I'm 50. I watched Benny Hill and Monty Python with my folks in the 70s. I watched Red Dwarf in the 80s and 90s on PBS here in Houston. On November 8 I bought Red Dwarf series XI on blu-ray, less than two weeks after it finished airing in the UK.

Monty Python: Introduction to North America

In the summer of 1974, Ron Devillier, the programme director for nonprofit PBS television station KERA in Dallas, Texas, started airing episodes of Monty Python's Flying Circus. Ratings shot through the roof, providing an encouraging sign to the other 100 PBS stations that had signed up to begin airing the show in October 1974—exactly five years after their BBC debut.

" the transmission line efficiency is about 50%"

You're way off on that one - How much electricity is lost in transmission and distribution in the United States?

The U.S. Energy Information Administration (EIA) estimates that electricity transmission and distribution losses average about 6% of the electricity that is transmitted and distributed annually in the United States. 1

all Teslas are automatic by default

"Manual" and "automatic" are terms used for describing how multi-ratio transmissions change which ratio is in use. Tesla only uses one ratio so there's no way to automatically, nor manually, change it. Transmissions that only use one ratio are known as a "simple".
