Delivering 8K VFX Shots For the Dark Knight

JCOTTON Re:8K? 18K? (263 comments)

What is a "K" in this context? I dont know. But here is a clue from comments to the original article:

Celboy, good question. Barbara went back to Paul Franklin at Double Negative and asked him to run us through the exact numbers. Turns out the 5.6K files took up a little less space than he had remembered. Here are his notes: ### 5.6K: 5616x4096; A full 5.6K was actually about 100 meg for the exr and 122 meg for the cineon/dpx; 8K: 8192x6144; approximately 150 meg for the exr and 200 for the cineon/dpx; exr files are run length encoded whereas cineon/dpx is not, so as well as being more efficient they also vary in size depending on how much detail (difference between pixels) there is on a frame to frame basis; My mistake on the downrez figure for the 8K to 5.6

Looks like the K indicates number of lines per frame. They use a formual to determine number of pixels per line *4:3 ratio or something like that.

2010 State Of The Mainframe Survey - alive and wel

JCOTTON JCOTTON writes  |  more than 2 years ago

JCOTTON (775912) writes "Here are the results of InfoSec's 2010 State Of The Mainframe Survey, which was conducted in July of 2010. The overwhelming result of the survey is that the mainframe is alive and well and will continue to be a critical component of the IT infrastructure going forward.
Most respondents indicated that they have stayed the same or grown over the past two years.
Key findings of the survey include:
59 percent of respondents indicated that the number of MIPS has increased or stayed the same over the past two years;
53 percent stated that their mainframe budget has increased or stayed the same over the past two years;
One-fourth (24 percent) stated that their mainframe staffing levels have increased in the past two years while 35 percent indicated they have stayed the same.
So all in all, it looks like the mainframe is going to be around for a long, long time.

COBOL: Don`t Call It a Comeback

JCOTTON JCOTTON writes  |  more than 6 years ago

JCOTTON (775912) writes "COBOL: Don`t Call It a Comeback
My experience (25+ years) has been, that when an applicant who is "very qualified" has a hard time finding a job, then the applicant has other, personal issues. Like, communication skills, inter-personal skills, or the like.
For example, early on in my career, a guy who was very qualified gave me his resume, and I forwarded it to my management. Well, he did things like fall asleep, bother people, and so on. He was fired in three months, after much coaching and hand holding. I had to leave that job too, not long after, due to being associated with that guy. So it goes.
(Another True Story) Someone who has "20 years mainframe systems" experience is going door to door begging, and in the mean time, a company has six mainframe openings, one person applies, and they reject him.
My advice is to get some personal coaching and hope that it takes and there is some improvement in your social skills. There are people who have absolutely no technical skills, and yet hold jobs. And there are people who are very technically qualified, and no one wants them around."

Why it's impossible to become a programming expert

JCOTTON writes "I have always been in awe of those guru types that seem to know everything on their subject. But most of us, myself included, have never mastered any particular segment of the cyberuniverse. Justin James tells me just what I wanted to hear. I am not alone in this — just the opposite."

Should I learn Java or stay with mainframes?

JCOTTON JCOTTON writes  |  more than 7 years ago

JCOTTON writes "CIOs of major corporations are agreed . They trust their mainframe systems more than they trust their distributed systems. But a "perfect storm" may be brewing. Many of the the mainframe Baby Boomer generation programmers will retire in the next decade. Deborah Perelman writes that CIOs should plan for this "problem".
I am a long time mainframe programmer, and I am now learning Java, JavaBeans, JDBC, and Swing, in order to switch to a more modern technology. My mainframe shop CIO says that we are moving to Java, but that our mainframe system will still be around in 10 years. Do Slashdot readers agree with my choice to learn Java? Or should I remain forever a mainframer? Do I trust my CIO?"

JCOTTON writes "Do you think that you have what it takes to go to MIT? Why don't you take a look at the introductory course in CS? There is no charge for viewing the course. But naturally, there are no academic credits or instructor help available either. You are on your own. But if you are a High School senior thinking about MIT, here is your chance to see what it is like on one of the most advanced technical schools on the planet."

JCOTTON writes "The FAA has released the Human Space Flight Requirements for Crew and Space Flight Participants
(Section 3) Pilot Qualifications As proposed in the NPRM, 460.5 requires a pilot of a launch or reentry vehicle to possess and carry an FAA pilot certificate with an instrument rating. The FAA invited public comment on the proposed requirement and received differing views.....in addition to a pilot certificate, the FAA (should) require test pilot credentials or military supersonic experience ....this could be a better choice to operate the vehicle than a pilot.

What does the Slashdot Space Academy think about the minimum qualifications for space pilot?"

JCOTTON writes "I just received a (large) box of 7400 digital integrated circuits. Now, as an electronics hobbyist and ham radio op, I have been tinkering with them. Usually, I work in analog circuits, i.e. radio receivers and transmitters. The question is: is there still a use or purpose for these digital chips? What would you do with a box of digital chips?"

JCOTTON writes "Slashdoters should stay aware of game technology. A "new" advance by IBM has taken the equivalent of five to fifty Wintel servers and put them in one, easily manageable and highly secure box. Hoplon Infotainment is reported to use this advance to "build a complex 'massively multiplayer' online game." CNN reports.
Yes, this is a MAINFRAME Story."



How much should college cost?

JCOTTON JCOTTON writes  |  more than 3 years ago

How much should college cost?
Making the math simple here: let's say one professor teaches five courses, each course has 20 students. Each student takes five courses per semester.
Each student pays 1/20 of the professor. If the prof makes 80K/yr then tuition should be $2000 per semester. Or $16K for a four year degree.
I understand this would be only for subjects where it is all classroom, such as Math, History, Literature, and the all important Liberal Arts.
I also understand that this does not include "overhead" such as classrooms, library, dorms, cafeteria, etc. I believe that donation should pay for buildings, not the students. And doing the math for classrooms and such, it comes to a relatively small amount, like $200/semester.
Technical subject like the Sciences would cost more, due to lab costs.
Athletics pays for itself, thru ticket sales.
Library should be paid for thru donations from alumni.
That is how much college should cost. But even in-state tuitions are triple this. Go figure.


Lets get back to basics

1. You know how you are always losing your phone in your house? Well, I have invented a phone that is connected to the wall with a curly cord. Yeh, really. You will never lose this phone. buddibum.
2. How about phones that communicate between each other without paying a carrier? I have that too. It is called "Ham Radio". buddibum
3. Passing data between programs running on an operating system...do you mean "streaming object serialization"...oh yeh, we have that too. COBOL. buddibum

And so on. XML is a solution looking for a problem. Get over it. Enjoy life and don't look back. It only repeats if you do look back.
