While most Apple users are focused on the newly announced iOS 15, young developer Zane Kleinberg has reworked iOS 4 – which Apple released in 2010 with the iPhone 3G – from the ground up as a standalone app. He calls it OldOS and you can try it out now. “What I created with OldOS is iOS 4 beautifully rebuilt in SwiftUI,” developer told Cult of Mac. “In essence, an app is something like an emulator or perhaps, a second operating system inside an app on your phone. It’s really designed to be a near-working, near-pixel-perfect re-creation of iOS 4.” The fourth version of Apple’s mobile operating system – and the first to be called “iOS” instead of “iPhone OS” – iOS 4 brought notable updates in 2010. It introduced new features. Home screen folder, support for adding custom backgrounds, system-wide spell checker integration and much more. Kleinberg sums up iOS 4 in one word: nostalgia. iOS 4 looks a bit dated these days – as a reminder of how far iOS has come over the past decade. But if you think iOS 4 brings a sense of nostalgia to you, it seems a lot more ancient for 18-year-old Kleinberg. He was 7 years old when it came out. “My first experience with any form of modern mobile technology was iOS 4,” New York-based developer said. “It’s hard to say how special this software holds in my heart. That’s what first introduced me to my passion for app development and technology. I think we all enjoy clinging to a select few childhood memories, and a lot of my memories include this operating system.” iOS 4 running on iPhone 12 A few years after the release of iOS 4, Kleinberg – then in 4th grade – created a homework tracker as the first app on the App Store. Even though that app was no longer available, he didn’t mind. He chose Computer Science when he took the university entrance exam at the end of this year. Zane Kleinberg Kleinberg created OldOS using a combination of legacy assets like icons and other things he had to design himself. He said he’s tried to recreate most of the iOS 4 apps. However, some apps – like Mail, Calendar, YouTube, and Messages – still have “big problems” he’s working on. Apps vary in functionality, with some functioning more fully than others. For example, the Calculator app can do calculations, but the Messages app (which is still active) only shows notifications and the UI. In other words, OldOS is more of an interactive museum than a fully functional operating system. “For months, I had an iPhone 4 running iOS 4 on my desk and used the apps one by one, trying to figure out how Apple designed them, ” I said. “ Since I’m pretty well versed in reverse engineering, I’ll decompile the application binaries and try to see, from a more technical perspective, how Apple built its app. I also found the iOS 4 UI Kits, and was able to put them in Photoshop and have a look.” Other parts of Kleinberg’s OldOS project require different methods. “For apps like Stocks and Weather, which no longer work, I watched YouTube videos, trying to reason as much as I could about the design,” I said. “ It’s just a continuous process of looking at different pieces of stuff over and over, then trying to build it in SwiftUI, and then iterating until I’m happy with that UI element.” Unfortunately, you shouldn’t expect to find this app in the App Store. Kleinberg believes that Apple will not accept the free use of assets owned by Apple. Apple enforces strict guidelines about showcasing its products in apps. “This whole project is a testament to the extraordinary work of the Apple team both past and present,” said Kleinberg. “I just hope this project can convince them to re-evaluate their policies even a little bit.” For those who want to try OldOS, Kleinberg says it can be downloaded from TestFlight, Apple’s developer service for beta-testing apps. Or they can check out his OldOS project on Github.

Besides Dogecoin, the posts also list a variety of cryptocurrencies with animal names, inspired by dog ​​breeds such as Akita, Shiba, Poodle… On many cryptocurrency discussion groups, administrators have voiced doubts about these articles, and commented that it is lame to rank FXT Token on a par with Dogecoin or Shiba. Posts promoting cryptocurrencies by many famous people in Vietnam. Posting about cryptocurrencies but don’t understand what “moon” is The fact that a series of artists have posted articles promoting the purchase of cryptocurrencies has many unusual signs. First, all articles have the same content, no difference in punctuation. They all only last a few hours before being deleted. In the comments section, many artists seem to lack the basics of cryptography. Actor Kieu Minh Tuan does not know the term “moon”, which is often used to refer to a sharp increase in money. Previously, singer Cao Thai Son was the first artist to publicly enter the cryptocurrency market with a portfolio that included Dogecoin. He often shares about his activities on his personal page. Post by Kieu Minh Tuan on personal Facebook. “Should you buy crypto right now? Advice: Buy as an asset with idle money, no leverage or interest,” the male singer wrote in a May 11 post. In the last week, when Dogecoin rose sharply, Cao Thai Son once posted to cheer for this coin, calling for everyone to invest. However, right after Dogecoin fell deeply, this singer posted a photo with the words “back to being a singer, no more analyzing stocks, crypto”. After Cao Thai Son, Ngoc Trinh also attracted attention when she published a post criticizing a cryptocurrency exchange that did not authenticate users (KYC) and claimed that she had been scammed by the exchange. While, delay in KYC is normal in exchanges. After that, she continued to post showing off her wallet on the exchange owning many millions of dollars worth of cryptocurrency. However, Ngoc Trinh deleted these posts, posted the article “duplicating the original” of other KOLs and then deleted it again. “Not only Huobi, many exchanges allow withdrawal of small amounts without KYC. Only when a large amount of money needs to be withdrawn does the user have to do KYC. It is incorrect to deposit such a large amount of money into the exchange without first finding out, and posting a post saying that the exchange is a scam,” commented Nguyen Vinh, co-founder of a large cryptocurrency investment company in Vietnam. Artists install advertising messages for multi-level? In the list of cryptocurrencies posted by the artists, in addition to the animal coins, there is a different coin, placed in the middle of the list is FXT. Previously, FXT was used as a fiat currency used for Lio****’s project. This project acts as a forex trading platform combined with binary options. This form of binary trading has long been warned as multi-level gambling. Instead of having to play on their own, investors in Lio**** are guaranteed to pay interest daily. The total profit for the whole year of this project is up to 2.3 times the original capital. The project has been warned by many domestic experts as a scam. In early 2021, many people lost money when Lio**** stopped working, not allowing money to be withdrawn from the account. The FXT coin is said to be directly related to the Lio**** multi-level project. Photo: VTV. Reply anonymously to Zing , a technology expert, and an administrator of the largest group of digital currencies in Vietnam, thinks that putting FXT in the middle of the list in the article is how artists advertise the product. by Lio****. “I think that a celebrity like Ngoc Trinh showing off a million-dollar e-wallet may be an implicit advertising act for FXT, not Dogecoin or Shiba. Because the time shown in the photo is quite different from when it was posted. Not to mention, the fact that many Vietnamese artists and celebrities share the same post content is very suspicious, “said this expert. On the same day, May 11, many screenshots of posts by Vietnamese artists were widely shared by the FXT Token community. “To Ngoc Trinh, Kieu Minh Tuan, Kha Nhu… still participating, what are you waiting for?”, the content of the status line reposted the screenshot of the person claiming to be the leader Lio****. In this article, the artist group also put the hashtag #trust. Trust English means “trust”, but can also refer to Trust Wallet, a software wallet technology that stores cryptocurrency. Previously, in the group of users who were deceived by Lio****, there were many warnings not to send money to Trust wallet to avoid losing evidence. On cryptocurrency discussion groups, members also pointed out that FXT is a suspicious name, because this coin has been launched since the end of 2020, and the call for investment has many signs of multi-level resemblance. . “These artists may be creating the image of a new multi-level project, aiming to attract a lot of small investors to clean up a big catch,” said LN, which runs a group on crypto. Many risks when investing in “junk coin” In the world of cryptocurrencies, in addition to large-cap coins with a good technology platform behind them, there are many so-called “junk coins” (very low value, arbitrarily created coins, copy the source code of reputable systems and some are served to scam groups). They are built on the available blockchain technology, often have no applications or come up with very simple applications, very low value but very high supply. Many experts warn that low-value, animal-based cryptocurrencies that have grown several times in the past few days are also very risky investments. These coins have a common model of using a cute image of an animal, a very small price, buying and selling many times to grow quickly. “These currencies all start at very cheap prices, at a fraction of a few tens of millions of dollars. They are created, then sent 50% to a certain celebrity for image, and then sold on exchanges. They use money to buy and sell themselves on these exchanges to increase the price thousands of times, creating momentum to put on the big floor. Because the number is so small, when the coin increases to a certain level, it has grown thousands of times, creating trust for ignorant people. When it comes time to be dumped, only those people will suffer,” said Vuong Le Vinh Nhan, founder of the VNDC trading platform. The Dogecoin price rose rapidly and reached an all-time high of $0.72 before cooling off. Photo: Coinmarketcap. Before that, the most successful animal crypto story was Dogecoin. Created as a joke, Dogecoin has been growing strongly for nearly a year as Tesla CEO Elon Musk repeatedly mentioned the coin. Over the past week, the price of Dogecoin has also fluctuated by tens of percent every day. Mike Novogratz, founder and CEO of Galaxy Digital, believes that two sharks own 30% of all Dogecoin today. In addition, Dogecoin also does not have a supply limit like Bitcoin. “The rise of Dogecoin is a prime example of the theory that fools more at play,” said David Kimberley, analyst at investment app Freetrade.

“FXT Token is a junk project” Launched at the end of 2020, FXT’s investment calling activity has many signs of multi-level resemblance. At its official website, FXT Token claims to be a “comprehensive financial solution that allows users to control their assets. A platform for providers and avails of financial services in cryptocurrency in when circumventing cross-border regulatory restrictions”. Post by Kieu Minh Tuan on personal Facebook. Do Phuong Quynh, a financial expert from Ant Group, Shanghai, China, said that FXT is “a junk project, the information in the White Paper is completely unhelpful. The individuals who run the project are not clear.” Quynh said. FXT is used as a fiat currency used for Lio****’s project. This project acts as a forex trading platform combined with binary options. This form of binary trading has long been warned as a type of multi-level combination gambling. Phuong Quynh assessed that FXT Token works in the same scenario as Wefinex’s WIN and Bitconnect’s BCC. “The project hits people’s ignorance and greed, by building a binary options platform, taking advantage of the reputation of the Forex trading market to trick investors into participating. Investors are promised. promise to pay interest every day, instead of planning to build a trading strategy like real traders,” added Quynh. Instead of having to play on their own, investors in Lio**** are guaranteed to pay interest daily. The total profit for the whole year of this project is up to 2.3 times the original capital. In early 2021, many people lost money when Lio**** stopped working, not allowing money to be withdrawn from the account. “FXT builds systems following the classic ponzi model to pay F1 and F2 players with the aim of enticing more people to join the system. Investors who do not have a background in finance often consider it This project is like a solution to help them earn money without labor”, Ms. Quynh warned. Sharing the same opinion, Mr. N. T, a representative of a blockchain incubator investment fund, said that FXT Token is associated with an unsustainable business model, mainly hitting greed. He said there are two types of people who will invest in FXT. “First, investors are ignorant of the mechanics and nature of the cryptocurrency market and forex investment. They are easily attracted by things that sound new, the stories are made up sounding. logic, terms that they are unlikely to understand, such as ‘technology 4.0’. This number may account for 80-90%,” said Mr. T. T. The second group of people listed by expert N. T are investors who understand the nature of these scam models, but think they can control the risks themselves. “They think they are quick, can invest early, withdraw early. But they themselves can’t control their greed later on. This number accounts for about 10-20%,” added Mr. T. The FXT coin is said to be directly related to the Lio**** multi-level project. Photo: VTV. FXT Token is only listed on small, less reputable exchanges like Bilaxy, FatBTC. In addition, the head office of the project is located in Vanuatu, the eastern island of Australia. The recommended company size is 51-200 employees. However, on Linkedin, there is only information of 4 profiles, including an individual who is Vietnamese. “To solve the biggest fear of investors is not being able to withdraw money, FXT has listed FXT Token on specialized exchanges or called ‘junk’ exchanges. In fact, these exchanges have no liquidity. , the value is manipulated, whether it can be sold or not is another story. Many investors are also deceived by the term ‘international exchange'”, said Mr. T. Sharing information about the listing standards of the world’s crypto exchanges today, Mr. T said that this standard is getting lower and lower, especially in less-known exchanges. “Currently, there are hundreds of exchanges. These exchanges want to ‘make a living’ also through coin listing. The less reputable the exchange, the lower the listing standard. They are willing to do everything for the money.” Mr T said. Expert N. T warns users if they lose money when trading on these exchanges, if they lose money, they are not protected by any party. ”A part of artists are aiding scams” Nearly a day after public opinion and crypto experts voiced the possibility of FXT Token’s fraud, Vietnamese artists who posted ads for this coin remained silent, with no statement to correct the incident. . “These days are crazy, people can teach each other things that are not their expertise. A part of the artist world is no longer aware of how dangerous their influence can be. to the people,” commented Mr. Phan Dung Khanh. Posts promoting cryptocurrencies by many famous people in Vietnam. Vietnamese artists should only do things related to entertainment, stay away from industries that are not well understood. “The fact that the official press channels warn of the possibility of fraud of dirty financial projects shows an attempt to clean up the national financial system. However, the artists defiantly ignored the scene. This is also an act of abetting fraud, disregarding the people and the law,” Quynh said.

In the world, it is true that there are many digital currencies (like Bitcoin) that are recognized by countries and in fact many entrepreneurs have become billionaires thanks to it. Many technology experts believe that digital currencies in the future will be encrypted with top secret, able to cross space, time, and transact easily… Of course, the current operating environment is only for transactions in one multinationals (there are large American companies that are even richer than a sovereign nation) are experienced enough; did not say anything on the internet. As long as some large enterprises accept the transaction (a certain digital currency) it can circulate within the allowed range. Recently, with the participation of billionaire Elon Musk (famous Tesla boss of South African origin), Bitcoin has skyrocketed in price. Because the community using digital currency is still a minority (compared to real money), it is still called virtual money. Because, transactions are still converted into real money (through strong currencies like USD). Just like real money, there are different types of virtual money. As a general trend, many digital businesses want to create their own currency. For example, even the social network Facebook also formed a coin called Diem (formerly named Libra). The problem is that in Vietnam, the currencies that are used by the world’s billionaires and some countries for the above transactions are not accepted by the authorities in the country. There are many reasons, but it is possible that controlling such coins is not easy. In addition to virtual currencies with “cheek numbers”, many fake “boss” set up floors and set up servers abroad to attract participants with huge profits. These brokers are called binary options trading (a way of betting to predict the price of virtual currencies, stocks rising/falling). Many times, its form is no different from a type of online gambling. Not to mention, with this virtual currency, football betting houses (overseas) or something similar can easily receive bets. Virtual money transfers are also difficult for the state to control through tax collection… Most importantly, both in the world and in Vietnam, many exchanges suddenly closed, collapsed due to the sudden death or escape of the owner. led to the deaths of tens of thousands of “mommoths”. The deaths are similar to the collapse of the multi-level system.
