Vapor chambers and heat pipes are exceptional at moving heat from a relatively small part of them to distribute it around the whole. This is because the heat dumps into a liquid which is concentrated at the heat source, but as soon as it ev

At some point I think I read a more complete justification, but I can’t find it now. There is evidence that it came about as a byproduct of the interaction of the HTML parser and JS parsers in early browsers. In this link we can see the exp

When a process crashes, its supervisor restarts it according to some policy. These specify whether to restart the sibling process in their startup order or to only restart the crashed process. But a supervisor also sets limits, like “10 res

The other comment explains this, but I think it can also be viewed differently. It’s helpful to recognize that the inner script tags are not actual script tags. Yes, once entering a script element, the browser switches parsers and wants to

This was my first submission, and the above comment was what I added to the text box. It wasn’t clear to me what the purpose was, but it seemed like it would want an excerpt. I only discovered after submitting that it created this comment.

How to safely escape JSON inside HTML SCRIPT elements(sirre.al)

Discussing why parsing HTML SCRIPT elements is so complicated, the history of why it became the way it is, and how to safely and securely embed JSON content inside of a SCRIPT element today.

You understand it correctly: it doesn’t remove any value from fixup; instead it just means you can fixup to whatever and move the commit visually to where you want it — doesn’t have to be the main/trunk branch, and you can do it whenev

You can interactively rebase after the fact while preserving merges even. I usually work these days on stacked branches, and instead of using —-fixup I just commit with a dumb message. git rebase -i --rebase-merges --keep-base trunk

No but I think I saw that it’s a thermal pad, one with comparable thermal transfer characteristics to the high end (non-conductive) pastes.

TECs are wonderful little devices with operating characteristics unlike comparable devices. They can be designed to move a specific amount of heat or to cool at some delta-T below the hot side (and due to inefficiencies the hot side can cli

Several years ago I replaced the thermal paste in my MacBook Pro and I did it in two steps: first to high-end paste; and second to liquid metal. The results were impressive, and I think it’s a bit veiled how paste degradation over time impa

Yes, that’s correct. All of these measures, of course, stand as a courtesy and are trivial to bypass, as ema notes. Finding cryptographic-strength measures to identify LLM-generated content is a few orders of magnitude harder than optimisti

Unicode has a range of Tag Characters, created for marking regions of text as coming from another language. These were deprecated for this purpose in favor of higher level marking (such as HTML tags), but the characters still exist. They ar

HyTime was Kimber’s work, and I found this reflections of his on “worse is better” to be quite refreshing, especially when contrasting the formality of SGML against the flexibility of HTML. https://drmacros-xml-rants.blogspot.com

HTML didn’t make sense to me until I realized it’s built on a state machine and its rules are based on what’s on the stack of open elements. For example, a number of tags trigger a rule to close open P elements or list items, and many end t

The story of XHTML is instructive to the field of software design. There are plenty of good resources on the web if you search why did XHTML fail ? HTML parsing at least is deterministic and fully specified , whereas XHTML, as an XML, l

The memory test is missing some deprecated and non-conforming elements. The HTML spec doesn’t have a single comprehensive list either, so it can be a little tricky to define or name “all” of the elements. For example, there are elements lik

Took me a while to process your response; thanks for providing to so much to think about. And yes, it is indeed nice meeting other SGML enthusiasts! Can’t say I’m familiar with the use of notations the way you are describing, and it doesn’t

Fun fact: this is very close but slightly inaccurate. I used to think this is how it worked before scrutinizing a rule in the HTML tree-building specification. The tag leads the parser to interpret everything following it as character data

I’ve become quite a fan of writing in SGML personally, because much of what you note is spot-on. Some of the points seem a bit of a stretch though. Any type-checking inside of SGML is more akin to unused-variable checking. When you say that

DOM\HTMLDocument is a huge boon. Niels Dosche incorporated lexbor into PHP to do so, and it maintains the same interface as DOMDocument once it’s instantiated. In case people aren’t aware, DOMDocument is dangerous. You can’t parse HTML with

Fun fact: HTML void elements came first. XML brought in "empty elements" by adopting SGML's "null end-tag" (NET), part of the SHORTTAG minimization (though it changes the syntax slightly to make it work). In SGML&#x

For better or worse XHTML, also known as the XML serialization of HTML, cannot represent all valid HTML documents. HTML and XML are different languages with vastly different rules, and it's fairly moot now to consider replacing them. M

I'm not entirely sure on this, but I believe that what we're seeing is the WASM runtime allocating memory for its potential needs, but not totally using it all. The entire filesystem, all the executables, all uploaded files, and a

the Playground can connect to a MySQL instance when running in a Node environment. it's not supported in the browser because there's no existing mechanism to relay the necessary socket connection there.

As noted above seven hours before your comment ;) the purpose for this project is for embedding interactive WordPress installations in documentation and to provide a playground in the browser for testing code or learning how to write plugin
