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' }); }

// 获取数据总数 public totalCount(): number { return this.dataArray.length; }

// 注册改变数据的控制器 registerDataChangeListener(listener: DataChangeListener): void { if (this.listeners.indexOf(listener) < 0) { this.listeners.push(listener); } }

// 在数据尾部增加一个元素 public addLastItem(card: Card): void { this.dataArray.splice(this.dataArray.length, 0, card); this.notifyDataAdd(this.dataArray.length - 1); }

public addDemoDataAtLast(): void { 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.

Elefant 2.2.4

Elefant 2.2.4 has been released with a number of bug fixes and improvements.

Click here to download or update.

Introducing JobQueue

This update adds a new JobQueue class which is powered by Pheanstalk/Beanstalkd. This makes it very easy to setup background workers and send tasks to them for processing.

Setup

To set it up, install Beanstalkd via your package manager of choice (apt/yum/brew/port), for example:

$ apt install beanstalkd

Next, after upgrading Elefant to 2.2.4, run Composer update from the root directory of your website to install the Pheanstalk library:

$ cd /path/to/www && composer update

Lastly, edit the [JobQueue] settings in your conf/config.php file to point to your Beanstalkd server:

[JobQueue] backend = beanstalkd host = 127.0.0.1 port = 11300

Usage

Sending a job to be done by a background worker is as easy as:

JobQueue::enqueue ('tube-name', ['data' => '...']);

Writing a worker in Elefant looks like this:

<?php // apps/myapp/handlers/worker.php if (! $this->cli) exit; $page->layout = false; $worker = JobQueue::worker (); $worker->watch ('tube-name'); while ($job = $worker->reserve ()) { $data = json_decode ($job->getData ()); // Process job with $data $worker->delete ($job); }

The above worker can be run via php index.php myapp/worker and can be initialized using your system scheduler, such as systemd.

Note that workers can be written in any language that connects to Beanstalkd and listens for jobs to process.

Other improvements

Added User::require_verification() which extends User::require_login() to require email verification too

Added Auto-include Composer autoloader to Site Settings form so you no longer need to include it manually in a bootstrap.php file

Waiting For the First Returned API Result With Promise.any() in JavaScript

Waiting For the First Returned API Result With Promise.any() in JavaScript

Promise.any resolves with the found value when the first promise successfully resolves. Which is useful for taking the fastest returning result from a set of slow or unstable APIs. For example, the below simulates different potentially slow APIs by using some with long timeouts:

function apiA() { return new Promise((resolve, reject) => { setTimeout(() => { resolve({ some: 'data', from: 'A' }); }, 1000); }); } function apiB() { return new Promise((resolve, reject) => { setTimeout(() => { resolve({ some: 'data', from: 'B' }); }, 200); }); } function apiC() { return new Promise((resolve, reject) => { setTimeout(() => { resolve({ some: 'data', from: 'C' }); }, 1500); }); } async function getData() { console.time('Promise.any completion time'); const data = await Promise.any([ apiA(), apiB(), apiC(), ]); console.info('Retrieved', data); console.timeEnd('Promise.any completion time'); // Retrieved { some: 'data', from: 'B' } // Promise.any completion time: 203.451ms (exact time will vary slightly) } getData();

Without that, some level of management code would be needed. Note that compared to Promise.race which is now supported by major browsers and Node.js, this only resolves by the first successful promise. Promise.race also resolves when any process causes an error.

For my example, I provided a simple Polyfill that does not do error handling since it was only for this example:

if (typeof Promise.any !== 'function') { // Only for example purposes. This does not implement the error handling of Promise.any. For a production ready // implementation instead consider libraries like Bluebird: https://github.com/petkaantonov/bluebird Promise.any = function(promises) { let resolved = false; return new Promise((resolve, reject) => { for (const promise of promises) { promise.then((result) => { if (resolved !== true) { resolved = true; resolve(result); } }); } }); } }

This will be necessary since Promise.any is in stage 3 which means that although the syntax is finalized, it is still awaiting implementation in most JS environments. If you need a production version of Promise.any(), it will be available in many Promise libraries like Bluebird: https://github.com/petkaantonov/bluebird

Github Location https://github.com/Jacob-Friesen/obscurejs/blob/master/2019/promiseAny.js

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.

WCF Data Services with Windows Phone - bandwidth requirements measured

In connection with testing Synchronization between a SQL Server Compact database on Windows Phone 8 and a SQL Server database (via a WCF Data Services service hosted in IIS), I have done some interesting observations regarding bandwidth requirements, that I would like to share. I am testing against the Chinook sample database, by downloading the entire PlaylistTrack table (8715 rows) to the device via my WCF Data Services service. On the server side, I am using the latest release version of the WCF Data Services server components, version 5.3.0. Version 5.1 or later includes the newer lightweight JSON format (just to compare I am also including sizes for the previous JSON format) On the server side, I have created a ASP.NET Web Application with a WCF Data Service, that exposes the Chinook database on my SQL Server via an Entity Framework DbContext. The power of WCF Data Services is that this requires basically no code to configure. I have configured my service like this: public class SyncService : DataService { // This method is called only once to initialize service-wide policies. public static void InitializeService(DataServiceConfiguration config) { config.UseVerboseErrors = true; //config.SetEntitySetAccessRule("TrackPurchases", EntitySetRights.WriteAppend); config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3; } } In order to access the IIS Express hosted service from my Windows Phone 8 emulator, I followed the instructions here: http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj684580(v=vs.105).aspx  To measure the size of the payload, I am using Fiddler2, by following the instructions here: http://blogs.msdn.com/b/fiddler/archive/2010/10/15/fiddler-and-the-windows-phone-emulator.aspx The WCF Data Services team also supply a WCF Data Services client for Windows Phone, that can take advantage of a Service Reference, but this client has some severe limitations, that affects bandwidth consumption in a bad way: It only supports the XML based ATOM format, but you can enable compression, as described here: http://blogs.msdn.com/b/astoriateam/archive/2011/10/04/odata-compression-in-windows-phone-7-5-mango.aspx  On the client side, I am simply using HttpWebRequest to call the REST url, and including support for gzip via the ICSharpCode.SharpZipLib library (for example http://nuget.org/packages/SharpZipLib-WP7/ ) Here is the implementation of the WebClient: static public async Task GetData(Uri uri, bool useJson = true, bool version3 = true, bool compress = true) { //uri = new Uri(uri.AbsoluteUri + "&format=json"); HttpWebRequest client = WebRequest.CreateHttp(uri); { if (compress) client.Headers = "deflate, gzip"; if (version3) { client.Headers = "3.0"; } else { client.Headers = "2.0"; } if (useJson) client.Accept = "application/json"; using (WebResponse response = await client.GetResponseAsync()) { string result = await response.GetResponseText(); DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T)); T resultType; using (MemoryStream stream = new MemoryStream(Encoding.Unicode.GetBytes(result))) { resultType = (T)serializer.ReadObject(stream); } return resultType; } } } public static async Task GetResponseText(this WebResponse response) { using ( Stream stream = response.IsCompressed() ? new GZipInputStream(response.GetResponseStream()) : response.GetResponseStream()) { using (var reader = new StreamReader(stream)) { return await reader.ReadToEndAsync(); } } } public static bool IsCompressed(this WebResponse response) { return Regex.IsMatch((response.Headers ?? "") .ToLower(), "(gzip|deflate)"); } (I am using Microsoft.Threading.Tasks.Extensions.dll to implement GetResponseAsync) I am using DataContext classes generated by my SQL Server Compact Toolbox for deserialization, with a small addition - I have added this attribute to all EntitySet and EntityRef properties (this will be included in the next Toolbox release): I am calling the following URL: http://:2065/SyncService.svc/PlaylistTracks This is my test code: //ATOM-XML await WebClient.GetData(uri, false, false, false); //Verbose json await WebClient.GetData(uri, true, false, false); //Verbose json + gzip await WebClient.GetData(uri, true, false, true); //Plain json await WebClient.GetData(uri, true, true, false); //Plain json + gzip await WebClient.GetData(uri, true, true, true); public class PlaylistTrackRoot { public List value { get; set; } } And finally the unbelievable numbers for the download of the entire PlaylistTrack table with 8715 rows (remember, that ATOM is the default WCF Data Services client format) Payload type Body size (bytes) Body size (MB) ATOM-XML 9,322,665 (100 % – default DS client implementation) 8.89 MB JSON (verbose) 5,016,977 (54 %) 4.78 MB JSON (verbose) + gzip 328,410 (3,5 %) 0.31 MB JSON (plain) 790,845 (8,5 %) 0.75 MB JSON (plain) + gzip 43,023 (0,5 %) 0.04 MB So before you decide to use the WCF Data Services Windows Phone client, beware that the only format currently available is ATOM-XML. With the 5.1.0 or later desktop client, however, you can use the of the DataServiceContext to request JSON - ctx.Format.UseJson() – the default is still ATOM-XML.

How To Recover Lost Data With USB Data Recovery

Have you ever experienced the heart-stopping panic of realizing that an important file or document is gone? In this article, we will discuss how to recover lost data with USB data recovery. We'll look at the steps involved in the process, what kind of data can be recovered, and what other options you have for rescuing your precious files.

How to Recover Lost Data on Your USB Data Recovery

If you have lost data on your USB drive, there are a few things you can do to try to recover it. First, try plugging the USB drive into another computer and seeing if the data is still accessible. If not, try using a data recovery program like Recuva or Pandora Recovery. These programs can scan your USB drive for any recoverable files and attempt to recover them.

If you're still having no luck, then it's time to try a more drastic measure: send your USB drive to a professional data recovery service. These services specialize in recovering data from all sorts of storage devices, including USB drives. They will be able to use their advanced tools and techniques to try to retrieve your lost data.

Of course, there is no guarantee that any of these methods will work, but it's definitely worth a shot if you've lost important data on your USB drive.

Professional Software for USB Data Recovery

There are many different software programs that claim to be able to recover lost data from a USB drive. However, not all of these programs are created equal. Some are more effective than others, and some are even scams. It is important to choose a professional program that has a good reputation in order to get the best results.

One such program is Recover My Files by GetData. This program has been around for many years and has helped thousands of people recover their lost data. It is very user-friendly and has a wide range of features that make it one of the most effective programs available. Another great option is EaseUS Data Recovery Wizard. This program is also very user-friendly and offers a wide range of features to help you recover your lost data.

If you are looking for a professional USB data recovery program, then these two options are definitely worth considering.

Tips to Avoid Losing your USB Data

As a general rule, it's always a good idea to have backups of your important data. That way, if you do lose your USB data for any reason, you can restore it from the backup.

There are a few specific things you can do to help avoid losing your USB data in the first place:

1. Use a USB drive with built-in encryption. This will help protect your data if the drive is lost or stolen.

2. Set up automatic backups to an external hard drive or cloud storage service. That way, if you do lose your USB drive, you'll still have a copy of your data.

3. Be careful when removing the drive from your computer. Eject it properly so that all data is safely written to the drive before it's disconnected.

4. Don't put all your eggs in one basket - use multiple USB drives for different purposes, and spread your important data across multiple drives (or even better, multiple locations). That way, if one drive is lost or damaged, you won't lose everything.

Conclusion

USB Data Recovery is a powerful tool that can help you recover lost data from your USB drive. It’s important to note that this process should only be used as a last resort, and if possible, it’s best to try other methods first such as using the Recycle Bin, File History or third-party backup software. If those methods fail, then you may want to consider trying out one of the many USB Data Recovery tools available on the market today. With these tips in mind, we hope you have been able to find an effective solution for your data loss woes!
