CSS Lessons Learned the Hard Way (Generate Conf)Zoe Gillenwater
Zoe Mickley Gillenwater gave a talk at Generate Conference in London where she shared several mistakes she made while learning CSS flexbox and other techniques. These included misunderstanding how flex-basis works, incorrectly using CSS transforms like rotateX, and making assumptions about screen reader support that caused accessibility issues. She emphasized that vulnerability and sharing mistakes openly can help both oneself and others learn. Making mistakes is a natural part of the learning process, and perfection should not be expected or feared.

It's been 6 years since the term Responsive Web Design (RWD) was coined and today is difficult to see new projects without implementing it. But this time has allowed us to see the implementation can be even more important than the technique and the theory.
The RWD covers from the performance to the implementation of patterns and "standard" behaviors to improve usability.
In this session reviewed tools, techniques and concepts to improve our projects:
- Performance and best practices
- CSS structuring and optization (BEM, SMACSS, etc.)
- Fixed-Pixel vs rem, em and %
- Responsive images. Drupal non-Drupal solutions and SVGs
- Asynchronous Javascript loading
- Typography in a responsive environment and FOUT, FOIT effects
- How proxy-based browsers like Opera Mini can affect, and how accessibility and Progressive Enhancement can help.
- Beyond the Mouse: Touch and keyboard events
- Using RWD patterns

Key aspects covered include using a naming convention based on modules, modifiers and descendants; avoiding overly specific class names; and including utility classes to add single styles without new classes. The document also provides examples of how to structure and name classes for common interface patterns.
HTML5 and CSS3: does now really mean now?Chris Mills
Code at http://people.opera.com/cmills/css3book/css3-html5-dnrmn.zip. The browser vendors love them! The browser fans and cutting edge designers are producing some really remarkable stuff, but what do HTML5 and CSS3 really mean for you, the pragmatic designer on the street? If you sidle up to one of those guys and whisper "but what about IE6 support", they are likely to slap you in the face, or run away with their hands clamped over their ears, yelling "la lala lala, I can't hear you." In this talk, Chris Mills will have a look at some of the new features of HTML5 and CSS3 - new semantics, video, media queries, rounded corners, web fonts, drop shadows and more. He will show real world examples, and then look at how they actually perform on those shady older browsers we are often called on to support. He will then look at strategies for providing support for those older browsers, including using JavaScript, fallbacks, and progressive enhancement.

Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?

Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data.
The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs.
Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution!
Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.
Kief Morris rethinks the infrastructure code delivery lifecycle, advocating for a shift towards composable infrastructure systems. We should shift to designing around deployable components rather than code modules, use more useful levels of abstraction, and drive design and deployment from applications rather than bottom-up, monolithic architecture and delivery.
Blockchain technology is transforming industries and reshaping the way we conduct business, manage data, and secure transactions. Whether you're new to blockchain or looking to deepen your knowledge, our guidebook, "Blockchain for Dummies", is your ultimate resource.

28. REPLACING ABBR
• <ABBR> element is used by screenreaders to expand abbreviations
like “lbs” or “NCAAP”
• However unintended consequences occurred trying to workaround
browser bugs for other HTML elements
• What happens when a screenreaders text like this:
• “Let’s go to <abbr class="geo"
title="30.300474;-97.747247">Austin, TX</abbr>”

data-imgtype=“mugshot”
alt=“John Smith’s mugshot”>

37. ARTICLE VS ASIDE VS
SECTION
• Marc Grabsanki says:
• Article is unique content to that document
• Section is a thematic grouping of content, typically with a heading -
pretty generic
• Aside is content that is tangentially related, like a sidebar
div has no meaning whatsoever, so there is nothing semantic about
divs
37
38. ARTICLE VS ASIDE VS
SECTION
• Bruce Lawson says:
• Aside is for something tangentially related to its parent element. Or, if a
sibling to the main content, it can be used to make sidebars of navigation,
recent comments, colophons, author bios etc.
• Article is a discrete piece of content that could be syndicated - a blog
post, a news item, a comment, a widget
• Section can also contain articles. for example, you could have a page with a
<section> full of entertainment articles, and a section of political news etc.
38
39. ARTICLE VS ASIDE VS
SECTION
• Molly Holzschlag, Opera standards evangelist, says:
• <section> clarifies <div>
• <article> 'replaces' <div id="content">
• <aside> 'replaces' <div id="sidebar">
• Chris Mills, Opera browser employee, plays it safe:

39
40. WHAT ABOUT THE DIVS?
• Marc Grabanski, jQuery and HTML5 guy:
• “div has no meaning whatsoever, so there is nothing semantic about
divs”
• Bruce Lawson, Opera browser employee:
• “Like all semantic questions, it depends on the context. If your only
reason for wanting an element is to group stuff for styling, it's a div.”

60. HTML5 AUDIO
• AUDIO element attributes are SRC, AUTOBUFFER, AUTOPLAY,
LOOP, CONTROLS
• If you don’t have CONTROL, player becomes transparent
60
61. HTML5 AUDIO SUPPORT
FF3.5+ S4+ Ch3+ Op10.5+ IE9+
Ogg
Y Y Y
Vorbis
MP3 Y Y Y
WAV Y Y Y
61
62. SUPPORTING AUDIO
<audio controls autobuffer>
<source src="html5audio.mp3" />
<source src="html5audio.ogg" />
<!-- include Adobe Flash player EMBED and OBJECT code
here -->
</audio>
Use Flash for older versions of IE
62
63. SUPPORTING AUDIO
• If you do insert audio, setting the file to autoplay is not recommended,
as it interferes with the experience for web surfers using screen
readers.
• Don’t use WAV file type.
• Better to ship a compact disc to the user instead.
63
68. HTML5 VIDEO
• WIDTH and HEIGHT should be required, IMO, but movie plays anyway
based on the values in the video file itself.
• Video formats may have their own posterframe. The browser should
use that by default unless overridden by valid POSTER attribute value.
• Text can be included within VIDEO element to allow user to download
video if their browser doesn’t support.
• If you want to give users control, use CONTROL attribute.
68
69. HTML5 VIDEO
• Video can start automatically if using the AUTOPLAY=”1” attribute and
value.
• Spec provides for LOOP, AUTOBUFFER which also take a value of O
or 1.
• Codecs support...
69
70. HTML5 VIDEO
“It would be helpful for interoperability if all browsers could
support the same codecs.
However, there are no known codecs that satisfy all the
current players: we need a codec that is known to not require
per-unit or per-distributor licensing, that is compatible with the
open source development model, that is of sufficient quality as
to be usable, and that is not an additional submarine patent
risk for large companies.
This is an ongoing issue and this section will be updated once
more information is available.”

audio-codecs-for-video-elements

71. CODECS
• Ogg (or “Vorbis”)
• No need to worry about patents
• H.264
• Created by the MPEG group
• If you have blu-ray disc player, you are using it
• WebM
• A wrapper for the VP8 video and Ogg audio streams
71
72. VIDEO CODEC SUPPORT
FF3.6+ S Ch5+ Op10.6+ IE9+
Ogg Y Y Y
H.264 Y Y* Y
WebM (W4.02+) (Ch6+) Y
72
73. LESSONS LEARNED
• To get most <video> support, you need 2 video files: H.264
and .OGG.
• iOS Devices can handle MP4 (H.264)
• Safari, IE, Flash can deliver MP4 (H.264)
• Firefox, Opera can deliver .OGG
• Then hit them with FLV video, which supports H.264
http://camendesign.com/code/video_for_everybody
73
77. LESSONS LEARNED
• Use VLC or Firefogg to encode common movie files types to OGG
• H.264 encoding? Use Handbrake
• If you are hot to trot for HTML5 Video, like, right now, check out Mark
Pilgrim’s tutorial:
http://diveintohtml5.org/video.html
• Good primer:
http://dev.opera.com/articles/view/introduction-html5-video/
77
85. SRT FILES
• SRT files are text files used in video playback; therefore, they do
not contain any video data.
• Text
file containing subtitles used by various video playback
programs; supported by DivX, DVD, and other video formats;
• Includesthe time each subtitle should be displayed followed by
the text of the subtitles.
• Subtitlefiles are often named according to the language of the
subtitles, i.e. "moviename-eng.srt" for English and
"moviename-ger.srt" for German subtitles.
