Internet of Things sensors for Raspberry Pi

Looking for good Internet of Things sensors for a Raspberry Pi? A pressure sensor or “force sensor” is a great pick. Great for precise, specific information in formally built environments, and it doesn’t require much computation to gain the information either, unlike cameras in an unstructured environment.

This is an “environment sensor”: air pressure, temperature, things like that.

Okay, this is a more heavy duty pressure sensor, not the kind of platform sensor you’d be looking for.

Video hosting on Facebook

So what about video hosting on Facebook? Is Facebook loosing money over their video hosting too or not? Well, that’s a challenge question. I would presume it is one of the things for sure that make their business’s finance tight. They might have an effective lossy compression scheme to throw away enough data to convince the user it is okay, even when the quality is in fact horrible, similar to their image hosting and uploading.

For sure they’re not going for broke by offering to host larger videos than they can pay for, unlike YouTube.

Again, I reiterate, because this is important!

It wasn’t just Paul Graham. Now the overall recommendation for images on the web is to only use progressive scan load versions, as modern web developers program other JavaScript-based tricks for getting what they want when images are still loading.

Chrome extension to reformat paragraphs?

Failed search.

Is there an extension for Google Chrome to reformat paragraphs?

Nevertheless, I found something else interesting. You know editable HTML containers in browsers? The implementation is actually quite horrible. You simply can’t have a WYSIWYG HTML editor.

Well, well… I should qualify things. You can’t copy-paste generic hand-written HTML into an HTML editor. Of course historically HTML was meant only to be generated by software, almost only software built into the operating system, so you get the point here.

Nested comments and C compilers

Very interesting. You can write a C program that when compiled, indicates whether the compiler allows nesting or not.

Well, I guess nested comments is a distinct artifact of the Borland C/C++ compilers. Most other mainstream compilers appear not to support it, but were explicitly rigged up so that they issue an error message should someone run through some Borland C/C++ code that contains nested comments.

This is a funny StackOverflow answer, in light of this knowledge.

Vim in WebAssembly

Interesting port of Vim to WebAssembly. However, instead of using traditional terminal emulation, this time through they’re rewriting a front-end in JavaScript, based off of the Windows/Mac front-ends.

Born digital

Born digital? It is very weird when you think about it. What is it, exactly? All works of artificial human authorship that can be entered directly into a computer device of some sort. If, however, it cannot be “directly entered,” it cannot be considered “born digital.” Now this can get quite tricky. Photographs can be “born digital,” but this does not extend to the objects that have been photographed.

Interesting article/viewpoint here. “Digital surrogate” is the term used for scanned copies here.
