I did this with a manual 35mm camera. You can purchase rolls of infrared sensitive film. You must make a focus adjustment when shooting infra red. Most manual camera focus rings have a second focus index mark, since infrared light focus converges slightly differently than natural light. See:

My hack was to purchase a 2017 vehicle with a 5 speed manual transmission. I reckon 95% of would be thieves can’t easily drive it away!

Alfred Wegener as the initial author on the theory of plate tectonics comes to mind. He was a trained meteorologist who observed the similarities between geological formations between the South American east coast and African west coast. He was lucky, in that his father in-law was a prominent geologist and helped him defend this thesis.

Pretty good if they did it in a day. Encountered the same issue and it took me at least three days to resolve. The issue presented itself as a database table not updating.

OP here. These are some really great ideas here and I thank you.

Now that would be a fun hack, no? I bet with the collective knowledge from this thread I might be able to pull it off.

I’m still working for the man, though.

I recall a time that I wrote a program that called for a tape mount and a file to be read where this file spanned 2 volumes. There was a 3270 terminal next to the tape reader. After the job is submitted, I was amazed at the velocity of the read.

The all time favorite raised floor data center story: I worked for a commercial software vendor back in the day where sufficient physical security for the data center was a lock on the building door, but no locks to the raised tile floor area.

One day I walked through the doors of the data center and everything was covered in a fine ash-like powder. Another employee brought their young child with him to the data center. This child pressed the red button labeled “Haylon Dump”.

I was told by the operators on watch that everyone was lucky to find their way out safely.

New locks were installed the next and badge swipes were required for entry.

Amazingly, all the hardware mostly survived.

Gary deWard Brown is the author and hence the name. If I recall, he also describes utilities like IEBGENER, IEBCOPY and so on.

One copy of the book on Amazon was over $100.

Great tip, thank you. Easy is relative. Lucky for me, I have kids who can get me going with a twitter account.

This is very helpful. I’m guessing you have a copy of the Brown/Blue => Blue/Brown book.

I’m guessing you also have a book recommendation on the history of the 360 architecture. Excluding Watson’s bio and “Mythical Man Month”, what book should I read next?

Ask HN: Forensic analysis for 50 year-old tape?

Im posting for a friend who moved recently. He found a magnetic tape that was written over 50 years ago. He says, if he recalls correctly, the tape would have contained 2 file, EBCDIC encoded, written by an IBM utility using a tape sub-system attached to a s/360 processor running MVS.Assume the IBM guys have this setup in some dusty basement in upstate New York.This is a 2 part question.

This! I would add, pick challenging projects. Interviewing and hiring is a two-way street. If the project is not one you deem to be technically challenging enough, then hold out for the one that is. Being a part of a competent team raises your skill level.
In my case, extremely useful as Google requested access to my location, and I declined. With this link, I get to read it with a tiny bit of anonymity. But, I do kid myself. Google already tracks me across multiple sites, so it becomes a small victory if I can find a way to deny them this one bit of data they would like to have.

A Volvo 240 DL, model years 2000 to about 2010. Completely reliable daily driver, safe, comfortable sedan that can goo 500,000 miles with reasonable care. I had three of them over the years. Today, my daily driver is a 2017 Toyota 4Runner after I put 250,000k miles on a 2008 Toyota Highlander. These can go 500,000 miles with reasonable maintenance. I also buy used so others take the depreciation hit.
This! I was constantly looking to grab the next rung up on the career ladder. Having kids made me rethink my priorities on helping them mature into happy, productive members of society. Sure, we made a pile of mistakes along the way in our child rearing efforts. I'm hoping the same, that they will remember me and my wife forever. I think they will.

You would be correct. Mine is "#1". I use compound english words whose meaning is non-sensical in a conversation but easy to remember.
> What you say feels to me as Joseph McCarthy has just sprung back to life.

No need to go that far back in the history of the U.S. Government spying on it's own citizens. In the late 1960's, the Nixon Administration used IRS data to spy on Vietnam war protesters, Dr. Martin Luther King, members of the Student's Non-Violent Coordination Committee, and other American citizens critical of the administration's foreign policy[1].

Human behavior being what it is means that eventually someone in the U.S. government will be tempted to use this data for nefarious purposes. Why should US citizens live in a survaillence state contrary to the Bill of Rights?

Re:Is that ship still stuck? on Friday March 26, 2021 @02:11AM (#26589218)
I agree with your reasoning here. I'm genuinely interested in your interpretation of the idiom, "whistling in the dark".

I have heard this as, "whistling in the wind", taken to imply sound waves are distorted by wind patterns since sound waves use air molecules for conveyance. Whistling into the wind would tend to dampen sound waves intended for up-wind listners. Whereas, whistling with the wind tends to cause a whistle with the same decibel level as the into-the-wind variety to travel a bit further to down-wind listners.

How would the medium of light impact travel distance of sound waves? Or is there a cultural reference here that is different for me as a American english speaker?

Some hiking trails are inherently dangerous for those ill-prepared. The Grand Escalante Staircase in Utah comes to mind. There is no cell signal and water sources are scarce. Beautiful slot canyon hiking and loads of fun, but it does carry an element of risk.
Except when they do go down. Not as a result of the processor itself, but as a result of the hiccups in the dependency chain.

In one case ours went down for a day when a backhoe hired for construction cut a power supply line. The data center batteries designed to give time for the desiel generator to kick-in were fine. The generator failed to start as a result of contaminated fuel despite monthly tests.

The second time was when an employee brought their 12 year old son into the raised floor environment. He found and pressed the haylon dump button for fire suppression. Staff were lucky to escape without suffocation.

The employee was fired and stricter entry requirements to the raised floor area were implemented.

Consider a subscription to the British newspaper The Economist. It began publication in 1848 in protest against the British corn laws. The writing is superlative written with a rather sly sense of humor.

In particular, they collect and graph enormous amounts of data to augment their articles. It's much better than random posts found on the internet.

This is the only book you need for JCL. Called, either the Brown-Blue book or Blue-Brown book.

This story also highlights the enduring strength of IBM's 360/370 architecture. It is still in widespread use today. The correct syntax is:

//SYSIN DD *

A data definition statement indicating the next line in the program is the start of the input program to be processed.
