HarmonyOS NEXT Practical: Waterfall Flow and LazyForeach

Goal: Implement waterfall flow images and text, and load waterfall flow sub items through lazy loading.

Implementation idea:

Create a Card model

Create WaterFlowDataSource data source

Customize WaterFlowVNet Component Custom Components

Implement WaterFlow and LazyForEach loops on the page

WaterFlow The waterfall container is composed of cells separated by rows and columns. Through the container's own arrangement rules, different sized items are arranged tightly from top to bottom, like a waterfall. Only supports FlowItem sub components and supports rendering control types (if/else, ForEach, LazyForEach, and Repeat).

Actual combat: WaterFlowDataSource [code] // An object that implements the iPadOS Source interface for loading data into waterfall components export class WaterFlowDataSource implements IDataSource { private dataArray: Card[] = []; private listeners: DataChangeListener[] = [];

constructor() { this.dataArray.push({ image: $r('app.media.img_1'), imageWidth: 162, imageHeight: 130, text: 'Ice cream is made with carrageenan …', buttonLabel: 'View article' }); this.dataArray.push({ image: $r('app.media.img_2'), imageWidth: '100%', imageHeight: 117, text: 'Is makeup one of your daily esse …', buttonLabel: 'View article' }); this.dataArray.push({ image: $r('app.media.img_3'), imageWidth: '100%', imageHeight: 117, text: 'Coffee is more than just a drink: It’s …', buttonLabel: 'View article' }); this.dataArray.push({ image: $r('app.media.img_4'), imageWidth: 162, imageHeight: 130, text: 'Fashion is a popular style, especially in …', buttonLabel: 'View article' }); this.dataArray.push({ image: $r('app.media.img_5'), imageWidth: '100%', imageHeight: 206, text: 'Argon is a great free UI packag …', buttonLabel: 'View article' }); }

Impression of Anoboy in Anime Streaming Sites and Audience

We have a constantly changing anime industry, moving with the times (technology and half of what every fan approves), influenced by notable figures regarding different movements. Of these voices, Anoboy has become a rising tide that lifts most anime streaming platforms up and also its viewership. The methods that he used for commentary and content creation, helped in shaping how his fans looked at anime through a different perspective hence providing him with the ground-breaking way ahead of streaming platform strategies.

How Anoboy is Shaping the Future of Anime Streaming

The influence Anoboy bestowed on anime streaming platforms confirms his place in the world of otaku. He effectively changed the way we talk about and consume anime commentary, which begat some significant shifts in the behavior of viewers and what streaming platforms see as strategy.

1. Engage and Discoveryunicast [×]arc edittrailerstvSeason 2, EPISODE 1The new way to watch video.

Among the most notable effects that Anoboy has on anime streaming platform is in increasing viewer engagement and discovery. Anoboy, are an online platforms that serve reviews for series obscure as well some hidden gems to the fans through there detailed analysis and collectible content. His suggestions and reviews guide viewers to check out new shows that might have been skipped over, keeping streaming sites working on expanding the field of anime they are willing to put in front of their audiences.

Anoboy often creates in-depth blogs about mainstream and obscure anime, guiding his followers to explore those...getData=url;forest(3,/portfolio/anisong-bikin-rng-gen-m-98-di-marketing-media/,true). It's why certain series are now attracting more traffic and viewership than they might've from the jump, changing how streaming services value their content.

2. Improving Content Curation and Discovery

As we know it, streaming platforms have long been trying to offer the best-personalized content product recommendations and influence from Anoboy EFFECTED how they too had redefined their curation strategy. Anoboy's more nuanced anime analysis and critique ability have proved the necessity of a recommendation algorithm that can be adopted to higher levels. The possibility that platforms are becoming more likely to contain curation lists and suggestions which are auto designed for this sort of in-depth analysis and thematic dialogue has existed for at least as long Anoboy.

Thus, for one instance; anime streaming services have now begun recommending themes or genres regarding the types of videos Anoboy talks about. This suggests users new series based on their tastes in commentaries.

3. Effect on Streaming Service Partnerships

The popularity of Anoboy is also changing the way streaming services think about working with creators. Given the reach and influence of Anoboy, it is no surprise that a number of streaming services are doing promotional campaigns with him as well exclusive content or even live events.

Often such partnerships are accompanied by special promotions or exclusive previews of anime content in the pipeline, which helps to build hype around series — Anoboy having garnered quite a bit of credibility and fanbase among fans. These collaborations allow platforms to draw in new subscribers or beyonden by providing original content and experiences around the most popular figures for example is Anoboy.

4. Setting a bar with both (for viewer expectations and content quality)

We anoboy have raised our standard to provide quality commentary on insightful anime discussion. As a result, most viewers who start engaging with content by anoboy in any way are exposed to higher standards and improved scope of anime-related stuff. This change in viewer perception has nudged the streaming services to put more emphasis on content power as well as innovation.

In terms of more widely available content, many other platforms are opting for HD streaming or improved subtitling — possibly even including bonus features such as behind-the-scenes footage and interviews with the creators. This new demand of higher quality and dynamic content, largely influenced by Anoboy as the catalyst resulted in an overall better streaming experience for those watching anime.

The Broader Anoboy Influence

This ultimately has a much broader and deeper impact compared to individual platforms or viewership trends. More broadly, his style of anime commentary — which has since taken root a bit more widely across the industry and influenced at least some people to think about engaging with my art form less shallowly than is typically considered normal for the ilk — spurred positive cultural movement within our little world here.

1. Fostering A Climate of Rigorous Discussion

Thanks to Anoboy for providing such detailed review and discussion which leads us in discussing this anime when serious discourses is being build by fans around the globe. This has provoked some similarly reasoned responses from other sides of the argument, which in turn affects how anime is reviewed and debated about within broader anime communities.

2. Diverse Representation of Anime

Anoboy covers all the mainstream hits and also, some of its lesser-known series has only helped growing diversity in anime content. This also encouraged streaming platforms to focus on more flexible anime that appeals to all sorts of types and varieties through the fandom.

3. HyperBeard Fosters the Next Wave of Creators

And For you guys who wanna become blog anime or YouTube commentators and are being asked about anoboy again, since AnoBoy has succeeded this can inspirated another younger brother in the age of booming 2019. His impact on upcoming creators is how anime commentary starts to grow into a colorful, moving landscape.

Conclusion

The impact of anoboy on anime streamers and viewers is visible in the way he built a huge fan base for himself. Anoboy, by encouraging audience participation and style curation acts as a bridge in changing how anime is consumed and discussed moving forward with the help of his superior quality video analysis. While Anoboy has already left an indelible mark on the anime industry, his influence can still be felt through waves that continue to develop and change with time.

Disclosure of CPU DoS due to malicious P2P message (≤ version 0.19.2)

A malformed GETDATA message could trigger an infinite loop on the receiving node, using 100% of the CPU allocated to this thread and not making further progress on this connection. This issue is considered Low severity. Details Before Bitcoin Core 0.20.0, an attacker (or buggy client, even) could send us a GETDATA message that would cause our net_processing thread to start spinning at 100%, and not make progress processing messages for the attacker peer anymore. It would still make progress processing messages from other peers, so it is just a CPU DoS with low impact beyond that (not making progress for attacker peers is a non-issue). It also increases per-peer long-term memory usage up by 1.5 MB per attacker peer. John Newbery opened PR #18808 to fix this issue by only disclosing the lack of progress. Attribution Credits to John Newbery for finding this bug, responsibly disclosing it and fixing it. Timeline * 2020-04-29 John Newbery opens #18808 * 2020-05-08 John Newbery reports his finding by email * 2020-05-12 #18808 is merged * 2020-06-03 Bitcoin Core version 0.20.0 is released with a fix * 2021-09-13 The last vulnerable Bitcoin Core version (0.19.x) goes EOL * 2024-07-03 Public disclosure. http://dlvr.it/T96bk8

Disclosure of censoring unconfirmed transactions to a specific victim (≤ version 0.20.2)

An attacker could prevent a node from seeing a specific unconfirmed transaction. This issue is considered Medium severity. Details Before this issue was fixed in PR 19988, the “g_already_asked_for” mechanism was used to schedule GETDATA requests for transactions. The SendMessages() function would send out GETDATAs for transactions recently announced by peers, remembering when that request was sent out in g_already_asked_for. However, this g_already_asked_for was a “limitedmap” data structure, with a bounded size that would forget the oldest entries if it reaches 50000 entries. This makes the following attack possible: * The attacker is the first to announce a legitimate transaction T to the victim. * The victim requests T from the attacker using GETDATA. * The attacker does not respond to GETDATA until close to the time when the victim would request T from other peers (~60 seconds). * Then, the attacker carefully spams the victim with bogus announcements, causing the victim’s g_already_asked_for to evict T. * The attacker announces T again to the victim (due to how the queueing works in m_tx_process_time, this does not need to be timed particularly accurately). * The victim, not finding T in g_already_asked_for will treat it as a new announcement, sending a new GETDATA for it to the attacker. * The attacker again does not respond to GETDATA. * etc. This way, the attacker can prevent the victim from ever requesting the transaction from anyone but the attacker. Attribution Responsibly disclosed by John Newbery, claiming discovery by Amiti Uttarwar and him. Timeline * 2020-04-03 John Newbery reports the bug in an email to Suhas Daftuar and others * 2020-05-08 John Newbery suggests an approach to fixing the bug * 2020-09-21 Pieter Wuille opens PR #19988 as a comprehensive approach to fixing this and other bugs * 2020-10-14 Pieter’s PR is merged * 2021-01-14 Bitcoin Core version 0.21.0 is released with a fix * 2022-04-25 The last vulnerable Bitcoin Core version (0.20.0) goes EOL * 2024-07-03 Public disclosure http://dlvr.it/T96bhn
