Trump remains silent on Nashville suicide bombing.
Paramedic Blues
Friend of mine trained as a paramedic. Top of his class, extra certifications, total commitment.
But he's a gentle leftie at heart, and the paramedic industry is staffed by ex-police specifically and right-wingers generally.
No way could he advance in the profession — his own instructor, who acknowledged his my friend's skill, also made things difficult. So my friend dropped out of the profession at the cusp of beginning.
Damned shame — he would have saved lives, *and* shown some humanity.
Pemdas
PEMDAS is an acronym used primarily in the United States as a mechanism to pedagogically enforce the order rules of computational precedence. PEMDAS is explained as follows:
- P parenthesis
- E exponentiation
- M multiplication
- D division
- A addition
- S subtraction
There are several obvious deficiencies with this model. For example, the fact that instances of the factorial operator are executed immediately after operations in parentheses and immediately before instances of exponentiation isn't indicated by this model. In addition, the ordering M-D (respectively, A-S) may appear to indicate that multiplication (respectively, addition) happens before division (respectively, subtraction), though multiplication (respectively, addition) receives the same precedence as division (respectively, subtraction).
It is not uncommon for American students to remember PEMDAS by way of any of a number of mnemonics, among the most common of which is, "Please Excuse My Dear Aunt Sally." Note, too, that there are analogues of PEMDAS in other countries as well, e.g., BODMAS (where B denotes brackets and O denotes orders) in the UK and BEDMAS in Canada (Pierce 2013).

Songs and Other Abuses by Feral Butler
Songs and Other Abuses (often simply Abuses) - album by Feral Butler
Tracks
- Microwave Urinal - allegedly co-authored by Fell Swoop
- Prosthetic Bidet
- Sumptuous Plumbing
Cromagnolin
Several tracks on Abuses feature the Cromagnolin, a hand-cranked pre-pleistocene device of wood, antler, and sinew which issues a quavering wail or moan approximating the vocables of Cromagnon-era hominids. Paleontologist-musician Frondo Ediacar was responsible for designing and constructing the Cromagnolin.
For extreme authenticity, Feral Butler formed an unlicensed transdimensional corporation which reverted the band members to proto-hominids for the duration of the recording session (and, by some accounts, beyond [citation needed]).

Strange Days
I liked "Strange Days" quite a lot. Conventional Hollywood tech-thriller fare, with violence and sex in abundance, but also with plenty of fresh tech ideas, a lavish visual style, and a downbeat remorse attitude which passes for conscience.

Russell's teapot
Russell's teapot is an analogy, formulated by the philosopher Bertrand Russell (1872–1970), to illustrate that the philosophic burden of proof lies upon a person making unfalsifiable claims, rather than shifting the burden of disproof to others.
Russell specifically applied his analogy in the context of religion. He wrote that if he were to assert, without offering proof, that a teapot, too small to be seen by telescopes, orbits the Sun somewhere in space between the Earth and Mars, he could not expect anyone to believe him solely because his assertion could not be proven wrong.
Russell's teapot is still invoked in discussions concerning the existence of God, and has had influence in various fields and media.
