Responsive Typography II
Your content is the most important feature of your website, so it's important to make sure that the text looks good and is easy to read no matter what device type or screen size it's being viewed on. One size does not fit all when it comes to typography, but you can use media queries to adjust type qualities such as size, line height, column width, margins, hyphenation, and even typeface depending on the viewport size. Learn how you can use CSS to apply design rules that will make your typography look better and perform better across devices. You'll also find out how typography affects the loading time of your website, and what you can do to improve performance.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

- 6. Taken from a Python/BeautifulSoup library.
- 7. (The Ruby is prettier, but who’s counting?)
- 9. It’s an edge case. MySpace’s HTML is worse than average.
- 10. But it is an ugly recipe for mental turmoil.
- 11. The alternative?
- 13. And you get back nice XML or JSON (or even SOAP!) (or even SOAP!)
- 14. But ‘D.R.Y.’! APIs break that principle. APIs break that principle.
- 15. This is the data equivalent of the ‘accessible version’.
- 16. Enter GRDDL.
- 17. GRDDL defines a transformation process for XHTML » RDF.
- 18. XHTML ? That’s what the spec says. That’s what the spec says.
- 19. HTML 4 works too. Tidy ! !
- 20. RDF? Yes. Trust me. It’s not evil. It’s not evil. It’s not evil.
- 21. GRDDL can work like a data stylesheet on top of your HTML. on top of your HTML. on top of your HTML.
- 22. You simply use HTML (or XML) in the normal way...
- 23. ...and define how the data transformation.
- 24. You can even use it as a bridge for exisiting APIs and services.
- 25. Could even be used for other formats than RDF. Atom? than RDF. Atom? than RDF. Atom?
- 26. Simple example: ‘Not Safe For Work’ ‘Not Safe For Work’
- 27. <a href=" http://tubgirl.com " class="nsfw">
- 28. I can write that. I can’t write xFolk by hand. I can’t write xFolk by hand.
- 29. Is ‘nsfw’ a good class name? No.
- 30. Do I care? No.
- 31. The data layer becomes separated like CSS is from HTML.
- 32. That’s the theory. Now for the demo. Now for the demo.
