Suggested April 2024 Twitter Adds New Simpler And Stronger Two

It just got tougher for malicious individuals to take over Twitter accounts. Today the microblogging giant is offering users a more robust two-factor authentication method to sign in to their accounts.

The new two-factor authentication is an application based verification, which basically means that it’s a system that provides a secure mechanism without having to rely on codes sent via SMS or other third-party solutions.

With the new mechanism users can enroll by using a supported mobile app, which will generate a 2048-bit RSA key pair. This is a private key that is store in the phone and a public key then is sent to Twitter.

The next time a user tries to sign in, Twitter will send a challenge based on a 190-bit, 32 character code, to the mobile app. Then the user gets a notification to approve or deny the sign in request. If approved, the app will automatically reply to challenge with the private key stored in the phone. Twitter verifies the entire transaction and only then the user is granted to get access to the social service.

According to a new article on WIRED, Twitter wanted to implement “two-factor”, but the company didn’t want to follow everyone’s footsteps (e.g., Microsoft, Google, Apple, etc.). As a result the new secure verification does not require a phone number, users can backup codes generated by writing it down on a piece of paper and storing it in a safe place (users can even use the code to access the social network from the web browser), and when new login request is made, users can verify and approve the request. Now you only need a the Twitter app and an internet connection.

Authenticate without a phone

If you don’t have your phone, the company has also a method to get around this scenario. Basically, you’ll need to use the backup code, which then is checked by Twitter’s servers and if the result matches, you’ll be able to sign in.

To make the backup code work without sharing secrets, we use an algorithm inspired by S/KEY. During enrollment, your phone generates a 64-bit random seed, SHA256 hashes it 10,000 times, and turns it into a 60-bit (12 characters of readable base32) string. It sends this string to our servers. The phone then asks you to write down the next backup code, which is the same seed hashed 9,999 times. Later, when you send us the backup code to sign in, we hash it one time, and then verify that the resulting value matches the value we initially stored. Then, we store the value you sent us, and the next time you generate a backup code it will hash the seed 9,998 times. — Twitter details.


To configure the new verification system in your Twitter account follow these step-by-step instructions:

1. Make sure you have installed the latest version of Twitter mobile app.

2. From the Me tab, open Settings and choose Security (Android users have to tap their name before selecting Security and users using a web browser simply need to scroll down on the Settings page and continue on the next step).

3. Enable Login verification.

4. Write down the generated backup code and store safely.

5. After you’re enrolled, you can use the Twitter app to approve or deny sign in requests from one or all your accounts.

The new end-to-end secure verification system is available today. Twitter is already pushing a new update to support the two-step authentication mechanism for Android and iOS, but sadly Windows Phone users will have to wait a bit longer. Also keep in mind that this new way to sign in to the social network is not a replacement to the already SMS-based login verification released back in May, it is just a new addition.

Forget Gnome And Kde, Xfce 4.8 Runs Simpler And Faster

A few times each month, I tire of the complexities of GNOME and KDE. Then I turn to a simpler, faster desktop for a couple of days or a week — and that desktop, more often than not, is Xfce. No other desktop I’m aware of balances convenience and speed half so well.

The only drawback has been that, until this week, the current version of Xfce has been a couple of years old and looking blocky and a little limited in what it can do. Consequently, the release of Xfce 4.8 is both welcome and overdue. The new release gives Xfce a facelift and some new enhancements to general functionality, settings, and — most of all — the panel, while not compromising previous releases’ functionality and lightweight.

This approach makes 4.8 seem a minor release by GNOME or KDE standards, but I suspect that I’m not the only one who wouldn’t have things any other way. Unlike the other major desktops, Xfce is a niche environment, and its success should be judged by how well it fills that niche — not on how many new features and applications can be crammed into it. It’s an attitude that may be timely, considering some of the changes due to arrive on the Linux desktop during 2011.

Ubuntu and Fedora, as well as pre-release packages for Debian and its derivative distributions. You may find that some of these packages are incompatible with existing Xfce utilities — for example, as I write, the Ubuntu packages are incompatible with the previous version’s Orage calendar.

A visual tour and release notes are also available, although the release notes are aimed more at developers than at general users.

Once the new version is installed, you can select it as your desktop as you log in.

You won’t see much in the way of new applications in the 4.8 release. About the closest you get is the new fuzzy clock for the panel, which indicates the time as “quarter past three,” instead of with the false precision of 3:15:25 insisted on by digital clocks. Otherwise, much of the new Xfce release looks superficially like previous versions with the same features hat are so simple that they appear subtle, such as dragging and dropping open windows in the virtual workshop indicator on the panel.

You will find some changes. For instance, the progress dialogs for moving or copying files now show the progress for individual files, rather than the overall progress of the entire process. Similarly, you can now drag and drop from application launchers from the panel, menu, or file manager to add them to the desktop — a simple step that Xfce has needed for several releases. Both these enhancements are small in themselves, but well in keeping with Xfce’s ongoing efforts to avoid unnecessary complexity.

The Xfce 4.8 desktop

These are the sorts of finishing details that quickly add up — and all too often are delayed in other desktops in favor of developing new features.

Still, on the whole, most of the biggest changes are behind the scenes. If you are a non-English speaker, you may notice substantial updates to translations in almost all aspects of the desktop from libraries to applications — not just in western European languages like French and German, but also Romanian, Greek, Hungarian, and Arabic.

Megapixels: Mini Frog, Two Frog, Pumpkin Frog, New Frog

Last week was chock-full of frog news, both heart-warming and heart-breaking. Here are the top four photo-worthy events:

See Sehuencas water frogs in love

Romeo (pictured above in all his orange tummy glory), was thought to be the last Sehuencas water frog in existence. Ever since biologists scooped him out of the wilds of Bolivia, he’s been the most eligible frog bachelor in the world. Most recently, the Global Wildlife Conservation group created a Match dot com dating profile in order to find Romeo his better half—by sending an expedition to South America. The search worked: biologists identified two males and three females of the same species in Bolivian cloud forests, densely-wooded regions perpetually enshrouded in canopy-level silvagenitus clouds. On Monday, the conservation group announced that Romeo had successfully bonded with a mate, aptly named Juliet. The two lovers can be seen below.

Lonely Romeo had stopped making mating calls altogether in 2023. But according to a press release, he began ribbeting again in March, after Juliet moved into his aquarium. The duo have so far struggled with mating, however. Romeo hasn’t assumed the right position for amplexus—the frog mating ritual where females lay eggs as the males fertilize them from behind—often enough or long enough (some male frogs can keep the shape for “week or even months,” according to a press release). But his caretakers remain hopeful.

Meet the new genus, Mini

Good things come in small packages. Andolalao Rakotoarison

Herpetologist Mark Scherz and his colleagues recently published a study in PLOS ONE announcing they’d identified five new miniature frog species in Madagascar. Three are named “Mini mum, Mini scule, and Mini ature, because I am HILARIOUS,” Scherz tweeted. He’s serious: the frog seen above, perched on a fingernail, is a real, live Mini mum. The new species have been described as “staple-sized” and “astronomically-small”. Going forward, the researchers hope to better understand how the frogs, which span three genera, evolved to be so teeny.

… And an invasive frog-killing fungus

The Helena’s marsupial frog, seen above, is a member of the Hemiphractidae family, which live in Central and South America. These photogenic amphibians are threatened by a deadly fungus, chytridiomycosis, or simply chytrid. The fungus is the most invasive species in the world, according to a new report in the journal Science. It has negatively affected a whopping 501 amphibious species. When chytrid creeps across the porous skin of a frog, toad, or salamander, it impedes electrolyte transport, and ultimately triggers a fatal heart attack.

Shine bright like a diamond. Sandra Goutte

Despite its cute common name, the pumpkin toadlet is actually a very poisonous frog. Its bright colors are a warning sign—a biological phenomenon called aposematism. But it turns out the frogs, native to the Atlantic forest along the coast of Brazil, have been keeping their niftiest feature to themselves. When Sandra Goutte, a postdoctoral associate at NYU Abu Dhabi, and her colleagues “discovered that Brachycephalus ephippium could not hear its own mating calls, they searched for alternative visual signals the frogs could use to communicate instead,” according to a press release. They shined a UV light on the hoppers, and were surprised to find their backs glowed. Turns out, the pumpkin toadlet’s skeleton is unusually fluorescent, according to the new research published Friday in the journal Scientific Reports. Because their skin is so thin, the UV lamp actually hit the bones of the two specimens under analysis, triggering that eerie gleam.

Lbank Hosts Third Edition Of “New Narratives For 2023” Twitter Space

On March 22, global crypto exchange LBank launched the third edition of the online AMA event “Exploring New Narratives for 2023” through its official Twitter account. Over 40,000 listeners tuned in to the previous two editions to hear what industry experts had to say about the current state of crypto and blockchain. This article compiles what insiders think about the impact of Federal Reserve rate hikes, their outlooks on the bearish market, meme coins, and the rise of CBDCs.

1. LuckyStar, Builder, BSDAO

LBank: You mentioned that Bitcoin’s Fear & Greed Index is currently hovering around 60, the highest level since November 2023. How much importance should be placed on that figure, and how much do you think it will fluctuate in the coming months?

LuckyStar: The recent fluctuations of Bitcoin’s price have confused many people. The surge in its price may be due to various factors, such as pressure on the banking system, a high likelihood of interest rate hikes, and the US government’s BTFP program, which injects liquidity into the market. However, Bitcoin’s value is still linked to the US dollar economy and is affected by trends on Wall Street, the US Dollar Index, and US bonds. The outbreak of COVID-19 and the Silicon Valley Bank incident have also affected the crypto market. The development of decentralized stablecoins may be an important narrative for the future of the crypto market.

The upward trend in the crypto market may continue until the end of April due to the provision of liquidity, although I am not very optimistic about the market in the second half of the year due to the possible domino effect that failing banks can cause. It is also possible that the crypto industry itself may repeat the same mistakes of the 2008 financial crisis.

2. chúng tôi Social Media Manager, Saito Network

LBank: Why do you always claim that meme coins matter for this industry?

nnova.eth: Meme tokens definitely are important and will play a significant role in the future of Web3. They are expanding beyond being just a token with the name of a dog species and actually building layer 1 ecosystems, which is a bullish signal. Memes are a form of cultural expression that can convey complex ideas in a simple format and can create a sense of community, and inspire people to take action. Meme tokens are high-risk assets, and it’s difficult to predict their market movements, but I suggest you keep an eye on the biggest meme projects nonetheless.

3. Jay Wong, Global Partnerships Manager, CB Recruitment 

LBank: Do you believe meme coins have sufficient utility and value?

Wong: I am not interested in meme coins, but do track the value and utility of a project. For example, Shiba Inu (SHIB) is a project that has a strong community, but I question whether the virality of meme coins is necessary to build a successful platform. I believe they may play a role in the future of gaming and in attracting a younger demographic. However, I want to see a value proposition from layer 1 and layer 2 projects that differentiate them from existing platforms. 

LBank: What are your thoughts on the adoption of CBDCs?

4. Sonny Kong, CFO, Superpower Squad

LBank: Arbitrum (ARB) has been making quite some waves in the industry. Why is that? 

Kong: Arbitrum is a layer 2 network based on the Ethereum blockchain, providing scalability and efficiency for dApps and smart contracts. Projects focused on solving real-world problems and improving user experience, like ARB, are more appealing to institutional investors. The recent trend of projects combining artificial intelligence, decentralized identifiers, and social media have the potential to create innovative applications and attract a larger user base. I expect to see more projects that offer new use cases and improve user experience in the blockchain space.

5. Crypto Meina, Founder of Crypto Meina Podcast

LBank: What will be the impact of further interest rate hikes on macroeconomics in the crypto market?

Crypto Meina: Raising interest rates to curb inflation could obviously lead to a liquidity crunch and slower economic growth, while the crypto market is likely to remain correlated with traditional markets in the short term. The Circle (USDC) pegging incident was an isolated event, but there may be more regional banks with similar situations. I recommend retail investors maintain a focus on quality assets like Bitcoin and Ethereum.

6. Victor Lee, CEO,

LBank: As a professional investor, what are your outlooks for the market sentiment toward the end of 2023?

Lee: The market is currently rebounding, despite this being contrary to the current Bitcoin housing cycle. Banks running out of money is the catalyst for this. While the sentiment among investors has not yet shifted, this contrarian trend is getting more obvious. The market will remain volatile and will continue to fluctuate for a good while.

LBank: In the past, you have brought up the conflict between regulation and the adoption of globalized digital assets like cryptocurrencies. What does that conflict look like? 

Lee: The government is controlling the most precious commodity in our lives; our money. People around the world are slaves to debt-based economies. Governments are minting more of their currencies, while Bitcoin and other cryptocurrencies are becoming more valuable. The government’s attempt to regulate and slow down the process of cryptocurrency adoption is a contrarian bet, but ultimately the free market will do its work and people will demand access to these products that allow them to control their own wealth.

LBank: What is your take on the adoption of CBDCs?

Lee: CBDCs will allow for easy transactions between different parts of the world without relying on intermediaries or centralized entities. Blockchain technology can replace the current financial system, but it will require time for people to adopt it. Besides that, CBDCs can bring more transparency to the financial system and hold the government accountable. Introducing CBDCs is a better way to improve the financial system rather than completely replacing it. The usage of CBDCs by banks and governments will be beneficial to everybody.

LBank: What are your thoughts on the adoption of CBDCs?

Naziroglu: Venture capitalists will eventually move towards government-backed digital currencies, and the adoption of CBDCs may actually be driven by interest rate hikes and the potential impact on inflation and debt for countries with currencies pegged to the US dollar. CBDCs could be beneficial for smaller nations looking to hedge against risks by allowing them to denominate their debt in their own currency. However, the adoption of CBDCs may come with the loss of some personal freedoms.

8. Joshua Sum, Co-Founder & Core Lead, College Dao

LBank: What is your take on the adoption of CBDCs?

Sum: CBDCs have a clear use case and are a step in the right direction, but central banks are not keen on them right now, and infrastructure and education are major hurdles. We are involved in blockchain education and believe that the industry needs to do a better job of teaching the public and lawmakers about this technology before we can achieve further adoption.

9. Samuel, Founder, EKOS LLC

LBank: Can you elaborate on the importance of the freedom to transact and how blockchain technology provides an alternative to centralized payments?

Samuel: While regulation protects consumers and maintains stability, recent actions by the US government indicate their interest in undermining the blockchain industry. Self-regulation using code and AI to translate this code into language can help solve the problem of understanding and verifying smart contracts. However, there’s a need for balanced rules that don’t undermine the core ideas of the industry and acknowledge that achieving this balance requires collaboration between the industry and regulators. 

LBank is preparing the next “Exploring New Narratives for 2023” Twitter Space. If you are interested in participating, don’t hesitate to contact us.

Apple Names Sabih Khan Svp Of Operations As Jeff Williams Adds New Design Responsibilities

Following the news that Jony Ive is leaving Apple this year, Apple has also announced that Sabih Khan has been named to its executive team. Khan will serve as Apple’s senior vice president of operations.

In a press release, Apple said that Khan will be in charge of its global supply chain:

In his new role, Khan will be in charge of Apple’s global supply chain, ensuring product quality and overseeing planning, procurement, manufacturing, logistics and product fulfillment functions, as well as Apple’s supplier responsibility programs that protect and educate workers at production facilities around the world.

Khan will report to Jeff Williams, Apple’s chief operating officer. Williams says that Khan is the most talented operations executive on the planet:

“I’ve been privileged to work with Sabih for more than 20 years, and you won’t find a more talented operations executive anywhere on the planet,” said Williams. “He is a world-class leader and collaborator, and I have no doubt that he will be the best leader of the Ops team in Apple’s history.”

The news comes following Apple’s announcement that Jony Ive will depart Apple this year to form his own design company, LoveFrom. While Apple will be a client of LoveFrom, Ive will not be an Apple employee.

Williams will oversee Apple’s design team following the change, hence why Khan is being promoted to a bigger operations role and likely taking some of Williams’ responsibilities. “Williams has led the development of Apple Watch since its inception and will spend more of his time working with the design team in their studio,” Apple says.

Apple’s full press release is below:

Cupertino, California — Apple today announced that Sabih Khan, a 24-year Apple veteran, has been named to the company’s executive team as senior vice president of Operations. Khan has played an important role in delivering each of Apple’s innovative products to market since the late 1990s, leading key product operations and supply chain functions. He continues to report to Jeff Williams, Apple’s chief operating officer.

In his new role, Khan will be in charge of Apple’s global supply chain, ensuring product quality and overseeing planning, procurement, manufacturing, logistics and product fulfillment functions, as well as Apple’s supplier responsibility programs that protect and educate workers at production facilities around the world.

“I’ve been privileged to work with Sabih for more than 20 years, and you won’t find a more talented operations executive anywhere on the planet,” said Williams. “He is a world-class leader and collaborator, and I have no doubt that he will be the best leader of the Ops team in Apple’s history.”

The Operations team is responsible for driving scale across the global supply chain and accelerating manufacturing innovation, including developing and scaling a new aluminum alloy that enables the use of 100 percent recycled aluminum in MacBook Air and Mac mini enclosures without compromising quality. The team also supports Apple’s environmental initiatives by partnering with suppliers to propel green manufacturing, helping conserve resources and protect the planet.

Before joining Apple’s procurement group in 1995, Khan worked as an applications development engineer and key account technical leader at GE Plastics. He earned bachelor’s degrees in Economics and Mechanical Engineering from Tufts University and a master’s degree in Mechanical Engineering from Rensselaer Polytechnic Institute (RPI).
