Glyph 0 must be assigned to a .notdef glyph. The .notdef glyph is very important for providing the user feedback that a glyph is not found in the font. This glyph should not be left without an outline as the user will only see what looks like a space if a glyph is missing and not be aware of the active font’s limitation.

It is recommended that the shape of the .notdef glyph be either an empty rectangle, a rectangle with a question mark inside of it, or a rectangle with an “X”

I have checked the following close stackoverflow sources : Relation passed to #or must be structurally compatible. Incompatible values: [:references]

So if you need to build an app like Uber, you should know the company approaches, technology, and business processes.

Different UX design teams follow different approaches in creating mobile-app wireframes. Some may help you come through with flying colors, while others may lead to failure. In this article, I’ll describe eight important steps that can help a mobile-app design company to build best-in-class wireframes for their projects.

I pushed the build files & tested it in my environment so this should work as is.

In engineering science, there is an emphasis on working prototypes or “deliverables”. As Professor of Computer Science Andries van Dam put it in an interview with the author, when engineers talk about work, they mean “work in the sense of machines, software, algorithms, things that are concrete ”  [Van Dam 1999]. This emphasis on concrete work was the same in Bush’s time. Bush had delivered something which had been previously only been dreamed about; this meant that others could come to the laboratory and learn by observing the machine, by watching it integrate, by imagining other applications. A working prototype is different to a dream or white paper — it actually creates its own milieu, it teaches those who use it about the possibilities it contains and its material technical limits. Bush himself recognised this, and believed that those who used the machine acquired what he called a “mechanical calculus”, an internalised knowledge of the machine. When the army wanted to build their own machine at the Aberdeen Proving Ground, he sent them a mechanic who had helped construct the Analyzer. The army wanted to pay the man machinist’s wages; Bush insisted he be hired as a consultant [Owens 1991, 24]. I never consciously taught this man any part of the subject of differential equations; but in building that machine, managing it, he learned what differential equations were himself … [it] was interesting to discuss the subject with him because he had learned the calculus in mechanical terms — a strange approach, and yet he understood it. That is, he did not understand it in any formal sense, he understood the fundamentals; he had it under his skin.  (Bush 1970, 262 cited in Owens 1991, 24)

If you've found a problem in Ruby on Rails which is not a security risk, do a search on GitHub under Issues in case it has already been reported. If you are unable to find any open GitHub issues addressing the problem you found, your next step will be to open a new one.

It's funny that in such a complex gem like this, there's only one open issue, exactly about what I came here to post.

Larry Wall famously said he was driven to create Perl by how difficult it was to solve a problem while coding, as well as by an abundance of 'laziness, impatience and hubris'

the impetus may have been more the challenge of creating a language of his own.

To an outsider, creating your own programming language might seem akin to saying 'I'll build my own airplane

And in our schools, we need to continue the work done by many states that are pursuing educative approaches to school safety and student success by reducing school exclusions and leveraging initiatives that strengthen students’ social-emotional skills, mental health supports, and sense of safety and belonging. If we genuinely want to ensure safer schools, we should follow the evidence about what works, rather than jeopardizing lives with ideological battles.

One was that they were .inspired by fear, the other that they were inextricably confused with defilement and hygiene.

Creating simulations, however, requires expert-level skills in interaction design, graphics, database functionality, and programming - not to mention instructional design, content expertise, and imagination.
