--ignore-unmerged When restoring files on the working tree from the index, do not abort the operation if there are unmerged entries and neither --ours, --theirs, --merge or --conflict is specified. Unmerged paths on the working tree are left alone. Holy smokes! I guess the git-ish fix for the user interface problem here will be to rename the option from --ignore-unmerged to --ignore-unmerged-except-in-cases-where-we-do-not-want-to-allow-that--consult-documentation-then-source-code-then-team-of-gurus-when-you-cannot-figure-it-out---and-wait-while-half-of-them-argue-about-why-it-is-right-as-is-while-the-other-half-advocate-adding-four-more-options-as-the-fix.

The console needs to be readable in development and to provide the best DX I have to design my libraries in ways that prevent these warnings. This results in design decisions that are detrimental to functionality and/or code readability/simplicity.

the errors that you get from JSON schema can sometimes be very confusing. I wanted to be able to generate errors that could easily be understood to speed up debugging time.

Just saying “snaps are slow” is not helpful to anyone. Because frankly, they’re not. Some might be, but others aren’t. Using blanket statements which are wildly inaccurate will not help your argument. Bring data to the discussion, not hearsay or hyperbole.

When there are imperfections, we rely on users and our active community to tell us how the software is not working correctly, so we can fix it. The way we do that, and have done for 15 years now, is via bug reports. Discussion is great, but detailed bug reports are better for letting developers know what’s wrong.

With the caveat that hero worship can be gross, distorting, and unhelpful to everyone involved, Svelte author Rich Harris (@rich_harris on Twitter) is one of my favorite open source developers. In the JS community he’s well-known among tool authors for spreading interesting ideas. He’s the creator of many open source projects including Rollup, the bundler of choice for many libraries including React and Vue.

Yet another comment with why is this not implemented is not helpful for devs.

the error/warning output about unresolved dependencies and missing global variable names doesn't provide any more information about which dependencies are part of the problem:

Why do I need a global variable? Is the global requirement from ES6 modules (I'd have thought modules would be in a functional scope) or rollup?

DX: start sapper project; configure eslint; eslint say that svelt should be dep; update package.json; build fails with crypt error; try to figure what the hell; google it; come here (if you have luck); revert package.json; add ignore error to eslint; Maybe we should offer better solution for this.

We could at least try to offer better error message for this, before it becomes our next NullPointerException, Segmentation Fault or Kernel Panic

In clinical psychology, treatment decisions are often guided by theories. Consider, for example, dissociative identity disorder (formerly called multiple personality disorder). The prevailing scientific theory of dissociative identity disorder is that people develop multiple personalities (also called alters) because they are familiar with this idea from popular portrayals (e.g., the movie Sybil) and because they are unintentionally encouraged to do so by their clinicians (e.g., by asking to “meet” an alter). This theory implies that rather than encouraging patients to act out multiple personalities, treatment should involve discouraging them from doing this role playing

Men are somewhat more likely than women to seek short-term partners and to value physical attractiveness over material resources in a mate. Women are somewhat more likely than men to seek long-term partners and to value material resources over physical attractiveness in a mate. But why? The standard evolutionary theory holds that because the male investment in becoming a parent is relatively small, men reproduce more successfully by seeking several short-term partners who are young and healthy (which is signaled by physical attractiveness). But because the female investment in becoming a parent is quite large, women reproduce more successfully by seeking a long-term partner who has resources to contribute to raising the child.

In psychology experiments there are numerous other things besides the independent variable that can cause change in the measured dependent variable. In chapter’s two to five we discussed at length how chance and measurement variability (or error) can produce the appearance of differences. We also discussed choices that experimenters can make when designing their experiments to reduce the influence of chance, such as increasing the number of observations, increasing the number of subjects, and improving measurement precision.
