    1. I’m proposing that writing those tests from the perspective of specifying the behaviors that we want to create is a highly valuable way of writing tests because it drives us to think at the right level of abstraction for creating behavioral tests and that allow us the freedom to refactor our code without breaking it
    2. I am a big advocate of having a complete test base and even erring on the side of caution when it comes to quality engineering and software validation but that is not what we’re talking about here. What we’re talking about here are the tests that we write when we’re doing test-first development and I’m proposing that writing those tests from the perspective of specifying the behaviors that we want to create is a highly valuable way of writing tests because it drives us to think at the right level of abstraction for creating behavioral tests and that allow us the freedom to refactor our code without breaking it.
    1. Having an understanding of higher level abstractions, such as tasks, activities and the historical code path taken, its debugging trace is much closer to how you, as an engineer, think about your code.
    2. Admittedly, both the signature and the return values of invoke feel a bit clumsy. That’s becaus we’re currently working with the low-level interfaces.

    1. Please note that this is a higher-level debugging tool that does not confront you with a 200-lines stack trace the way Ruby does it, but pinpoints the exceptional code and locates the problem on a task level. This is possible due to you structuring code into higher abstractions, tasks and activities.
    1. When compiling assets with Sprockets, Sprockets needs to decide which top-level targets to compile, usually application.css, application.js, and images.
    1. Using a terminus to indicate a certain outcome - in turn - allows for much stronger interfaces across nested activities and less guessing! For example, in the new endpoint gem, the not_found terminus is then wired to a special “404 track” that handles the case of “model not found”. The beautiful thing here is: there is no guessing by inspecting ctx[:model] or the like - the not_found end has only one meaning!
    1. But all of these attempts misunderstand why the Open Source ecosystem is successful as a whole. The ecosystem of fairly standard licenses provides a level playing field that allows collaboration with low friction, and produces massive value for everyone involved – both to those that contribute and to those that don't. It is not without problems (there are many essential but unsexy projects that are struggling with funding), but introducing more friction won't improve the success of this ecosystem – it will just lead to some parts of the ecosystem to break off.

    1. From morn to night

      We started the poem at the beginning of the day and now end at night. Not only does this show the "circle motif" in this poem - what I mean is how "all things come to a close" and then restart anew - but it also parallels the journey of the youth, from being naive and blissful to being to falling victim to that naivety and becoming unaware of their fictitious bliss in the unknown; the journey leads to isolation from reality.

    2. folly=inescapable

      Blake shows how youth can be unaware that they have been corrupted. When they are brought down a path of ignorance, they become trapped in the dark, unless a light appears to guide them. Youth have few doubts, and when that is fed into, they continue without doubts, content with not having opposing views and nuance - stuck in their own folly.

    3. Doubt is fled=stuck to their opinions

      Doubt is fled seems very much like a point on the youths lack of internal questioning. They do not think there is room for doubt, as they must be right - a point made from their lack of understanding the nuance of truth and reality.

    4. delight=bliss in not understanding?

      Does this mean that there is delight in not understanding truth? It is the youths who are delighted, relating to their lack of experience.

      p.s This poem is taken from Selected Poetry and Prose of Blake (section Songs of Experience)

    1. This is acceptable because the standard security levels are primarily driven by much simpler, symmetric primitives where the security level naturally falls on a power of two. For asymmetric primitives, rigidly adhering to a power-of-two security level would require compromises in other parts of the design, which we reject.

    1. Variation in Rates of Fatal Police Shootings across US States:the Role of Firearm Availability

      Hello! This article is about the relationship between firearm prevalence (the IV) and the rates of fatal police shootings (the DV). The authors hypothesize that the greater the prevalence of firearms, the grater the rates of fatal police shooting.

      This article follows the classical structure of social science research -- abstract, introduction, literature review/theory, research design, findings, and conclusions.

    1. Instead of continuing the millennia old search for the universal ontology, different types of ontologies have been proposed in computer science. [.] [C]lassification of ontologies [is] based on their granularity and [their] thematic scope [differs] into top-level, domain, task, and application ontologies ...

    1. In contrast to his concept of a simple circular orbit with a fixed radius, orbitals are mathematically derived regions of space with different probabilities of having an electron.

      In this case, the QM model allows for probabilistic radii, not fixed radii, and the quantization is the energy level. An electron with principal quantum number n = 2 will always have quantized energy corresponding to \( E = R(1/n^2) \), but the exact minimal and maximal radial distance from the nucleus is not specified as in the Bohr model of the atom. Similar to the Bohr model though, the most probable radial distance is quantifiable, and that is the radius the electron is most likely to inhabit, however it will be found elsewhere at other times.

    1. Title: The dying breed of craftsmen behind the tools that make scientific research possible - LA Times

      Keywords: government-funded research opened, snake glass coils, fuse glass beakers, organic chemistry, research hubs, world war, experienced glassblowers, glassblowers remain, church laboratory, befallen glassblowing, glass manufacturer, glass technicians, cost-cutting world, jobs tend, entry-level jobs

      Summary: Hunkered down in the sub-basement of the Norman W. Church Laboratory for Chemical Biology, underneath a campus humming with quantum teleportation devices, gravity wave detectors and neural prosthetics, Rick Gerhart chipped away at a broken flask.<br>Peering into the dancing flames, he examined his work for wrinkles — imperfections invisible to the untrained eye.<br>“It not only should be functional,” he said, smoothing the rim with a carbon rod, “it has to look good.”<br>Here in Caltech’s one-man glass shop, where Gerhart transforms a researcher’s doodles into intricate laboratory equipment, craftsmanship is king.<br>In a cost-cutting world of machines and assembly plants, few glassblowers remain with the level of mastery needed at research hubs like Caltech.<br>“He’s a somewhat dying breed,” said Sarah Reisman, who relied on Gerhart to create 20 maze-like contraptions for her synthetic organic chemistry lab.<br>Rick Gerhart, scientific glass blower at Caltech, has been helping to make scientific research possible at the campus since 1992.<br>(Dillon Deaton/Los Angeles Times)<br>Similar fates have befallen glassblowing at UCLA and NASA’s Jet Propulsion Laboratory.<br>Across the U.S., those who land such jobs tend to stay until retirement.<br>He chuckled: “Looks like we have to steal somebody.”<br>To master scientific glassblowing, proper training and apprenticeships are key.<br>In addition to the hands-on training, which requires a knack for precision as well as coordination, students must take courses in organic chemistry, math and computer drawing.<br>So it really takes a long time to get to a position like Rick’s.”<br>Gerhart enrolled in the Salem program in 1965, after dropping out of college to give his father’s profession a try.<br>The craft, which dates back to alchemy in the 2nd century, took hold in America by the 1930s and 1940s, after World War I cut off glassware supply from Germany.<br>The profession peaked after World War II, when booms in oil and government-funded research opened up numerous glassblowing jobs in many a lab.<br>At first, Gerhart hopped around a number of firms and worked alongside more experienced glassblowers at TRW Inc. and UCLA.<br>When he settled at Caltech in 1992, the glassblower before him handed over the key to the shop and said, “Good luck.” On his own, Gerhart pieced together his patchwork of experience to twist and fuse glass beakers and snake glass coils over vacuum chambers.<br>“That’s when I really started learning.”<br>Social media videos have sparked new interest in the craft, Briening said.<br>But while his students have no trouble getting entry-level jobs at companies like Chemglass Life Sciences, a glass manufacturer, and General Electric Global Research, rarely are universities willing to budget the overhead costs for more than one glassblower, if any.<br>“Years ago, all the universities had two or three people,” Briening said.<br>One of the few resources left for the next generation is the American Scientific Glassblowers Society, a close-knit group that hosts national workshops and swaps ideas when a researcher’s custom order stumps one of its members.<br>Its members also serve as Caltech’s best — and possibly only — options once Gerhart leaves.<br>“Rick’s one of those glass technicians that I put in the top 5%,” Ponton said.<br>
