We all know how to enable a website using apache on Linux. I'm pretty sure that we all agree on using the a2ensite command.

Unfortunately, there is no default equivalent command that comes with Nginx, but it did happen that I installed some package on ubuntu that allowed me to enable/disable sites and list them.

The problem is I don't remember the name of this package.

Does anybody know what I'm talking about?

Please tell me the name of this package and the command name.

Browser detection using the user agent

Serving different Web pages or services to different browsers is usually a bad idea. The Web is meant to be accessible to everyone, regardless of which browser or device they're using. There are ways to develop your website to progressively enhance itself based on the availability of features rather than by targeting specific browsers.

But browsers and standards are not perfect, and there are still some edge cases where detecting the browser is needed. Using the user agent to detect the browser looks simple, but doing it well is, in fact, a very hard problem. This document will guide you in doing this as correctly as possible.

Note: It's worth re-iterating: it's very rarely a good idea to use user agent sniffing. You can almost always find a better, more broadly compatible way to solve your problem!

The humble favicon was messily birthed with the pernicious IE5 release. Since that fateful day, browsers have slowly expanded favicon technology to encompass many wildly differing and lightly documented use cases. Here in 2021 favicons are found primarily in browser tabs, home screens, and Google search results, but they continue to pop up in the strangest places.

Recently my team was tasked with building a favicon fetcher. As a warmup, I looked to see how Chrome handles favicon loading. Do you know that the favicon loader in Chrome is many thousands of lines of code? Why is it so complicated?

We realized we knew very little about the favicon ecosystem. Eventually we decided to fetch the Tranco top 100,000 websites and analyze their favicons. We checked each home page for favicons, Apple touch icons, and manifest icons. We also examined fallback locations like /favicon.ico. Here’s a quick table to catch you up: //

The big winner is the mesmerizing favicon from eventhorizontelescope.org, clocking in at a hefty 7MB. When I downloaded this favicon, the density of my machine increased and nearly collapsed into a black hole.

SSG Site Pros

• Developer-Focused: Hand-coding websites is a pain in the Lance Bass. It's fun to be artisanal for a second, but once you get into dozens (hundreds, thousands) of pages, it becomes frustrating and confusing. On the dynamic side, manipulating WordPress and Squarespace to do all you know is possible can be frustrating (I know that the folks who work on these teams work very hard to improve dev experience as it's a weak spot in most dynamic site generators).
• Separation of Concerns: SSG sites maintain the separation of visual presentation and content. You can continue to write new content as Markdown files without manually applying styling to it as you would with a hand-coded static site.
• Reusable: Global changes to templates (e.g., blog post template) and components (e.g., navigation) are made by editing one file instead of many.
• Metadata: One of the most powerful aspects of SSGs is that it surfaces the metadata: the title of the page, published date, site taxonomy, hero image, etc, can be defined and changed without touching the templates themselves, reinforcing the separation of concerns. Metadata is surfaced in something called front matter, which allows the content maintainer to add and customised data to the literal front of their file. (I'll talk more about this and show examples when we dive into Eleventy's structure in part II.)
• Lean: As with a static site, the delivered files are what they are. It takes up less room on the internet, which is minimalist and aligns with our designer ways (rerolls turtleneck collar).
• Fast: Lessening the number of server requests means your site will be faster, which improves your SEO and user experience, providing better access to more users.
• Economic: Most SSGs are free to set up.
• Asset Management: On static sites, asset management is largely manual; you might run individual photos and CSS files through some processes. On dynamic sites, image handling is automated and quite dialed in by way of plug-ins and platform-wide support. Most SSGs include some sort of process for assets, including compiling, transpiling, minifying, and bundling assets. SSGs provide build processes for anything from photo management (serving appropriately sized images) to CSS minification (rewriting your CSS into what the browser needs to read rather than what's optimal for developers to read).
• Build Customisation: Most SSGs allow you to manipulate how the build process happens. So, if you want to see the site refresh live as you make edits, that's usually possible. If you want to check for specific linting processes, that's possible too.

This proposal concerns the management of general information about accelerators and experiments at CERN. It discusses the problems of loss of information about complex evolving systems and derives a solution based on a distributed hypertext system.

Overview

Many of the discussions of the future at CERN and the LHC era end with the question - ªYes, but how will we ever keep track of such a large project?º This proposal provides an answer to such questions. Firstly, it discusses the problem of information access at CERN. Then, it introduces the idea of linked information systems, and compares them with less flexible ways of finding information.

It then summarises my short experience with non-linear text systems known as ªhypertextº, describes what CERN needs from such a system, and what industry may provide. Finally, it suggests steps we should take to involve ourselves with hypertext now, so that individually and collectively we may understand what we are creating.

Losing Information at CERN

CERN is a wonderful organisation. It involves several thousand people, many of them very creative, all working toward common goals. Although they are nominally organised into a hierarchical management structure, this does not constrain the way people will communicate, and share information, equipment and software across groups. //

A problem, however, is the high turnover of people. When two years is a typical length of stay, information is constantly being lost. The introduction of the new people demands a fair amount of their time and that of others before they have any idea of what goes on. The technical details of past projects are sometimes lost forever, or only recovered after a detective investigation in an emergency. Often, the information has been recorded, it just cannot be found. //

The problems of information loss may be particularly acute at CERN, but in this case (as in certain others), CERN is a model in miniature of the rest of world in a few years time. CERN meets now some problems which the rest of the world will have to face soon. //

A solution: Hypertext
Personal Experience with Hypertext

In 1980, I wrote a program for keeping track of software with which I was involved in the PS control system. Called Enquire, it allowed one to store snippets of information, and to link related pieces together in any way. To find information, one progressed via the links from one sheet to another, rather like in the old computer game "adventure". I used this for my personal record of people and modules. It was similar to the application Hypercard produced more recently by Apple for the Macintosh. A difference was that Enquire, although lacking the fancy graphics, ran on a multiuser system, and allowed many people to access the same data. //

"Hypertext" is a term coined in the 1950s by Ted Nelson [...], which has become popular for these systems, although it is used to embrace two different ideas. One idea (which is relevant to this problem) is the concept: "Hypertext": Human-readable information linked together in an unconstrained way. //

We should work toward a universal linked information system, in which generality and portability are more important than fancy graphics techniques and complex extra facilities.

The aim would be to allow a place to be found for any information or reference which one felt was important, and a way of finding it afterwards. The result should be sufficiently attractive to use that it the information contained would grow past a critical threshold, so that the usefulness the scheme would in turn encourage its increased use.

The passing of this threshold accelerated by allowing large existing databases to be linked together and with new ones. //

I imagine that two people for 6 to 12 months would be sufficient for this phase of the project.

A second phase would almost certainly involve some programming in order to set up a real system at CERN on many machines. An important part of this, discussed below, is the integration of a hypertext system with existing data, so as to provide a universal system, and to achieve critical usefulness at an early stage.

(... and yes, this would provide an excellent project with which to try our new object oriented programming techniques!)

• mondrian: Art in the style of Piet Mondrian.
• triangles: A colorful triangle mesh.
• circles: Circles packed together.
• tiles: A maze created using the 10 PRINT Commodore 64 generative art program.
• cubic-disarray: Inspired by the art of Georg Nees.
• joy-division: Inspired by Joy Division's Unknown Pleasures album cover.
• 123: Inspired by Vera Molnar's Un Deux Trois artwork.

A demonstration of what can be accomplished through CSS-based design. Select any style sheet from the list to load it into this page.

The Zen Garden aims to excite, inspire, and encourage participation. To begin, view some of the existing designs in the list. Clicking on any one will load the style sheet into this very page. The HTML remains the same, the only thing that has changed is the external CSS file. Yes, really.

CSS allows complete and total control over the style of a hypertext document. The only way this can be illustrated in a way that gets people excited is by demonstrating what it can truly be, once the reins are placed in the hands of those able to create beauty from structure. Designers and coders alike have contributed to the beauty of the web; we can always push it further.
