Macintosh SE second monitor, battery replacement info

Important!

This was that Macintosh SE article that I’ve found that has a second monitor connected to the Macintosh. This appears not to tell of the battery specifications.

What should we use for the replacement battery on the Macintosh SE? This. “3.6V Lithium 1/2 AA PRAM Battery for Mac.” Actually, this is pretty easy to buy from Batteries Plus+. Just look for a lithium 1/2 AA. Make sure you specifically ask for a lithium battery as you do not want the battery to leak inside of your vintage computer equipment.

The batteries used in the Macintosh computers listed in the specs tab are lithium, and are 3.6V.

Beware, however, that the early Macintosh SE just solders the battery directly into the board. The later models like SE/30 and SE FDHD use a socket to make the battery easily removable. The recommendation?

you can solder in place a battery socket for a “1/2 AA”; the same type of PRAM battery used by the SE/30 and like Mac models sharing that battery.

Security training links

So, yeah, with this security culture stuff. We’ve been put through some not-so-great security training, and here are some links I’ve saved from that. Well, actually that is an understatement. The security training is actually quite horrible in quality. The security training base material was “proprietary,” but it was all based off of publicly available sources, except for the internal company policies.

Random articles on Hollywood and discrimination/diversity

When searching for info on non-silver black and white film, I found this instead.

20170816/DuckDuckGo black and white film non-silver

OFF-TOPIC:

20170816/http://www.indiewire.com/2014/01/why-white-people-dont-like-black-movies-162548/
20170816/https://www.quora.com/Why-do-most-Hollywood-movies-rarely-have-non-white-people-Is-it-due-to-racism-or-something-else

Short answer: The sole purpose of Hollywood is to make money, and that means targeting the demographic that has the most money. In other words, the primary solution to solving the demographic problem would be to improve the representation of the minorities in the middle class

But wait. The first article brought up an interesting point. There was a “Black film renaissance” in the early 1990s, and there appears to be one coming back in the early 2010s. (The article was published in 2014.) You know what I’m wondering? Could it be the case that diversity in the media is directly linked to the strength of the economy? Well, given your logical assertions above, this would be correct. When the entire economy is doing better, minorities are better represented in the media.

More searching on the Caffenol organic film developing process. So, comments?

  • First of all, a lot of people prefer the developing process because you don’t have to work with smelly chemicals. Or, chemicals that smell bad.

  • Second, how do you remove the tannin for better results? Well, my search results weren’t very informative, but preliminary evidence suggests that you should use some sort of filter system to remove it. Perhaps one designed to extract the tannin would be most useful for getting all the other chemicals on one side.

Ah yes! This link has some example photos. Remember, this is a black-and-white development process only. If you use color film, you will get black-and-white results.

Pinhole camera and binoculars sun projection

Pinhole camera? Great for photographing the sun, especially during an eclipse.

You can also use binoculars to project an image of the sun, but do you really need an image that bright?

Make your own film developer from coffee

Make your own film developer? You can use coffee to do that.

So, although home-made film developer is promising, home-made film is a bit more difficult. Coating the film with the photosensitive material is a bit more complicated, and getting the photosensitive material? You might have to buy that specially.

So in other words, the most expensive material in traditional photography is the photosensitive material. Finding a way to make that material cheaper will make all of traditional photography suddenly magically cheap.

Other, less promising sources.

Any news on Raspbery Pi Zero? Nope, no news, it seems it kind of trailed off… yeah, just like the end of all fads. People will proudly announce when it starts, but nobody really is around and interested to talk about when it’s over.

Important! Ansible notes.

Add to ansible.cfg:

callback_whitelist = profile_tasks

to enable profiling and get timestamps on task execution.

20170720/https://github.com/jlafon/ansible-profile

Important! Ansible notes. Have that silly problem with host key checking causing connections to fail? Use this environment variable setup:

ANSIBLE_HOST_KEY_CHECKING=false

20170728/https://stackoverflow.com/questions/23492032/cant-disable-ansibles-host-key-checking#23494998

Do you want to specify a list or other complex variables in an inventory file? Use single quotes (‘’) to quote it.

20170729/https://stackoverflow.com/questions/18572092/how-specify-a-list-value-as-variable-in-ansible-inventory-file?rq=1

Important! Is it possible to write Ansible hosts/inventory files in YAML? Yes.

Ansible notes.

Important! How do you have one task run on the local machine rather than the remote? Use the delegate_to task property.

delegate_to: localhost

20170710/http://docs.ansible.com/ansible/playbooks_delegation.html#delegation

There are also methods to have the entire playbook run locally.
