This Extension Adds Audio Visualizer on Desktop in Ubuntu 22.04 | 22.10

Want to display audio/music visualizer on the desktop? This extension can do the job for Ubuntu 22.10, Fedora 37, Arch/Manjaro Linux with GNOME.

It’s “Sound Visualizer” extension for Gnome Shell based on Gstreamer specially for Wayland. And, it’s working good in my case in Ubuntu 22.04, though it’s said for Gnome v43.

Besides for music playback, it works when any sound play from your computer. And, it has a right-click menu to switch between input/output audio sources. Meaning, it supports sounds input from microphone.

How to Install this “Sound Visualizer” desktop widget

1. (For Ubuntu 22.04 only) As mentioned, the extension supports GNOME v43 at the moment of writing. If you want to try it out in 22.04, first disable extension version validation.

To do so, press Ctrl+Alt+T on keyboard. When it opens, run command:

gsettings set disable-extension-version-validation true

2. Next, open Ubuntu Software. Search for and install ‘Extension Manager‘ tool for installing and managing Gnome Shell extensions. Or, run command in terminal in case the Software App does not work.

sudo apt install gnome-shell-extension-manager

Install Extension Manager in Ubuntu 22.04+

3. Finally, launch ‘Extension Manager‘, and navigate to ‘Browse‘ tab. Search for and install the ‘Sound Visualizer‘ extension. (For Ubuntu 22.04, just click on Unsupported button)

For Fedora 37, Arch and Manjaro Linux with GNOME, visit this page in web browser and use the ON/OFF switch to install it.

4. After installation, try playing some sounds and see your desktop for the result. To move the widget, you have to temporarily disable “Desktop Icons NG (DING)” under ‘Installed’ tab in Extension Manager.

You can also adjust the visualizer size by opening the extension preferences either via widget’s context menu or by clicking the gear button for that extension in Extension Manager.

Happy 13th Birthday, KrebsOnSecurity!

KrebsOnSecurity turns 13 years old today. That’s a crazy long time for an independent media outlet these days, but then again I’m bound to keep doing this as long as they keep letting me. Heck, I’ve been doing this so long I briefly forgot which birthday this was!

Thanks to your readership and support, I was able to spend more time in 2022 on some deep, meaty investigative stories — the really satisfying kind with the potential to affect positive change. Some of that work is highlighted in the 2022 Year in Review review below.

Until recently, I was fairly active on Twitter, regularly tweeting to more than 350,000 followers about important security news and stories here. For a variety of reasons, I will no longer be sharing these updates on Twitter. I seem to be doing most of that activity now on Mastodon, which appears to have absorbed most of the infosec refugees from Twitter, and in any case is proving to be a far more useful, civil and constructive place to post such things. I will also continue to post on LinkedIn about new stories in 2023.

Here’s a look at some of the more notable cybercrime stories from the past year, as covered by KrebsOnSecurity and elsewhere. Several strong themes emerged from 2022’s crop of breaches, including the targeting or impersonating of employees to gain access to internal company tools; multiple intrusions at the same victim company; and less-than-forthcoming statements from victim firms about what actually transpired.


You just knew 2022 was going to be The Year of Crypto Grift when two of the world’s most popular antivirus makers — Norton and Avira — kicked things off by installing cryptocurrency mining programs on customer computers. This bold about-face dumbfounded many longtime Norton users because antivirus firms had spent years broadly classifying all cryptomining programs as malware.

Suddenly, hundreds of millions of users — many of them old enough to have bought antivirus from Peter Norton himself back in the day — were being encouraged to start caring about and investing in crypto. Big Yellow and Avira weren’t the only established brands cashing in on crypto hype as a way to appeal to a broader audience: The venerable electronics retailer RadioShack wasted no time in announcing plans to launch a cryptocurrency exchange.

By the second week of January, Russia had amassed more than 100,000 troops along its southern border with Ukraine. The Kremlin breaks with all tradition and announces that — at the request of the United States — it has arrested 14 people suspected of working for REvil, one of the more ruthless and profitable Russian ransomware groups.

Security and Russia experts dismiss the low-level arrests as a kind of “ransomware diplomacy,” a signal to the United States that if it doesn’t enact severe sanctions against Russia for invading Ukraine, Russia will continue to cooperate on ransomware investigations.

The Jan. 19th story IRS Will Soon Require Selfies For Online Access goes immediately viral for pointing out something that apparently nobody has noticed on the U.S. Internal Revenue Service website for months: Anyone seeking to create an account to view their tax records online would soon be required to provide biometric data to a private company in Virginia —

Facing a backlash from lawmakers and the public, the IRS soon reverses course, saying video selfies will be optional and that any biometric data collected will be destroyed after verification.


Super Bowl Sunday watchers are treated to no fewer than a half-dozen commercials for cryptocurrency investing. Matt Damon sells his soul to, telling viewers that “fortune favors the brave” — basically, “only cowards would fail to buy cryptocurrency at this point.” Meanwhile, is trying to put space between it and recent headlines that a breach led to $30 million being stolen from hundreds of customer accounts. A single bitcoin is trading at around $45,000.

Larry David, the comedian who brought us years of awkward hilarity with hits like Seinfeld and Curb Your Enthusiasm, plays the part of the “doofus, crypto skeptic” in a lengthy Super Bowl ad for FTX, a cryptocurrency exchange then valued at over $20 billion that is pitched as a “safe and easy way to get into crypto.” [Last month, FTX imploded and filed for bankruptcy; the company’s founder now faces civil and criminal charges from three different U.S. agencies].

On Feb. 24, Russia invades Ukraine, and fault lines quickly begin to appear in the cybercrime underground. Cybercriminal syndicates that previously straddled Russia and Ukraine with ease are forced to reevaluate many comrades who are suddenly working for The Other Side.

Many cybercriminals who operated with impunity from Russia and Ukraine prior to the war chose to flee those countries following the invasion, presenting international law enforcement agencies with rare opportunities to catch most-wanted cybercrooks. One of those is Mark Sokolovsky, a 26-year-old Ukrainian man who operated the popular “Raccoon” malware-as-a-service offering; Sokolovsky was busted in March after fleeing Ukraine’s mandatory military service orders.

Also nabbed on the lam is Vyacheslav “Tank” Penchukov, a senior Ukrainian member of a transnational cybercrime group that stole tens of millions of dollars over nearly a decade from countless hacked businesses. Penchukov was arrested after leaving Ukraine to meet up with his wife in Switzerland.

Tank, seen here performing as a DJ in Ukraine in an undated photo from social media.

Ransomware group Conti chimes in shortly after the invasion, vowing to attack anyone who tries to stand in Mother Russia’s way. Within hours of that declaration several years worth of internal chat logs stolen from Conti were leaked online. The candid employee conversations provide a rare glimpse into the challenges of running a sprawling criminal enterprise with more than 100 salaried employees. The records also reveal how Conti dealt with its own internal breaches and attacks from private security firms and foreign governments.

Faced with an increasing brain drain of smart people fleeing the country, Russia floats a new strategy to address a worsening shortage of qualified information technology experts: Forcing tech-savvy people within the nation’s prison population to perform low-cost IT work for domestic companies.

Chipmaker NVIDIA says a cyberattack led to theft of information on more than 71,000 employees. Credit for that intrusion is quickly claimed by LAPSUS$, a group of 14-18 year-old cyber hooligans mostly from the United Kingdom who specialized in low-tech but highly successful methods of breaking into companies: Targeting employees directly over their mobile phones.

LAPSUS$ soon employs these skills to successfully siphon source code and other data from some of the world’s biggest technology firms, including Microsoft, Okta, Samsung, T-Mobile and Uber, among many others.


We learn that criminal hackers are compromising email accounts and websites for police departments worldwide, so that they can impersonate police and send legal requests to obtain sensitive customer data from mobile providers, ISPs and social media companies. That story prompts revelations that several companies — including Apple, Discord and Meta/Facebook — have complied with the fake requests, and draws the attention of Congress to the problem.


It emerges that email marketing giant Mailchimp got hacked. The unknown intruders gained access to internal Mailchimp tools and customer data by social engineering employees at the company, and then started sending targeted phishing attacks to owners of Trezor hardware cryptocurrency wallets.

The FBI warns about a massive surge in victims from “pig butchering” scams, in which flirtatious strangers online lure people into investing in cryptocurrency scams. Investigative reports reveal pig butchering’s link to organized crime gangs in Asia that attract young job seekers with the promise of customer service jobs. Instead, those who show up at the appointed time and place are kidnapped, trafficked across the border into neighboring countries like Cambodia, and pressed into a life of indentured servitude scamming others online.

The now-defunct and always phony cryptocurrency trading platform xtb-market[.]com, which was fed by pig butchering scams.


KrebsOnSecurity reports that hackers who specialize in filing fake police requests for subscriber data gained access to a U.S. Drug Enforcement Administration (DEA) portal that taps into 16 different federal law enforcement databases.

The government of Costa Rica is forced to declare a state of emergency after a ransomware attack by Conti cripples government systems. Conti  publishes nearly 700 GB worth of government records after the country’s leaders decline to pay a $20 million ransom demand. Continue reading “Happy 13th Birthday, KrebsOnSecurity!”

How User Experience Designers Help You Achieve a Great User Experience

User experience design comprises the execution of a wide range of activities to create an experience that is appealing, fast, and easy to navigate. In short, creating an interactive interface that helps customers perform their tasks. Salesforce User Experience Designers (UX designers) are one of the most sought-after professionals in the digital industry today, with the job titles often being interchangeably used with User Experience Manager (UEM), User Interface Designer (UIX), and Product Designer.

This blog defines how people can use user experience design to boost productivity and to better connect with marketing segments.

What Is User Experience Design?

User experience design (UX) is the process of creating a product that feels like humans designed it. UX’s goal is to make digital products as intuitive, efficient, and enjoyable as possible.

User experience design focuses on the end user and how they interact with a product. It’s not just about aesthetics; it’s about ensuring your website or app works well on all types of devices and browsers with different screen sizes and resolutions.

It involves researching the target audience, understanding their needs and goals, and designing a product that meets those needs. People can use the Salesforce User-Experience-Designer study guides available on multiple platforms to gather important information about the subject.

How does User Experience Design Impacts productivity?

User experience design is not just about aesthetics. The process of creating a good user experience has many other benefits.

It helps users to save time and effort in the use of a product. It also saves money on maintenance costs, including human resources and equipment. A good user experience reduces the need for additional training or support from technical experts.

User experience design can make products easier to use, increasing productivity by reducing user error. For example, when you open an email in your browser, it should look like a web page instead of an application window with a limited amount of text or information displayed simultaneously.

Hence, making message viewing possible without having to click through multiple pages of information before finding what you’re looking for.

The Importance of User Experience Design

User-Experience-Designer pdf is critical for designers to define goals. User experience is the success of any business application. A well-designed application can help businesses increase productivity, while a poorly designed application will only lead to frustration and decreased productivity. Hence, businesses invest in UX design to ensure their applications deliver a great user experience.

User Research and Interaction Design

Conducting User-Experience-Designer practice tests and user research is essential to understanding how users interact with business applications. This research and User-Experience-Designer practice dumps help businesses identify areas where they can improve their application to deliver a better user experience. Once the research is complete, businesses can use interaction design to make the necessary changes.

Designing the Information Architecture

The User-Experience-Designer dumps and information architecture of an application are critical to its success. A well-designed information architecture will help users find the information they need quickly and easily. A poorly designed information architecture will only lead to confusion and frustration.

Creating prototypes and conducting user testing

Once the information architecture has been designed, businesses can create prototypes of their applications. These prototypes can then be user tested to ensure that they are easy to use and provide a great user experience.

Implementing UX design can help businesses boost productivity, save time and money, and better connect with their target market segments. By investing in UX design, businesses can create applications that deliver a great user experience and drive tangible results.

The Elements of Good User Experience Design

Good user experience design must consider the needs of users, application business goals, and the technical constraints of the platform. UX designers must balance these three factors to create an effective and intuitive application.

The user must be able to accomplish their goals with the application. This includes finding the information or features they need, understanding how to use the application, and feeling comfortable using it.

The business goals of the application must be achievable. This means that the application must be able to meet the specific needs of the business. For example, if the business goal is to increase sales, the application must be designed to make it easy for users to purchase products.

The technical constraints of the platform must be considered. This includes ensuring that the application is compatible with the devices that users will be using, including any other software the application must integrate.

Creating a great user experience requires a deep understanding of all three elements. UX designers must have a strong understanding of human behavior, old User-Experience-Designer study material, and the ability to think creatively and solve problems.

The Benefits of Good User Experience Design

Good user experience design can have benefits that can be summarized as follows:

  1. Helps businesses achieve their goals.
  2. Makes applications more intuitive and effective.
  3. Increases productivity.
  4. Reduces frustration.
  5. Can help businesses save money.

Good user experience design is essential to the success of any business application. By investing in UX design, businesses can create more effective, intuitive, and engaging applications, leading to increased productivity.

The Most Common Mistakes in UX Design

The most common mistakes in UX design are:

  1. Not understanding the user.
  2. Not considering the business goals.
  3. Not taking into account the technical constraints.
  4. Not thinking creatively.
  5. Not being able to solve problems.

These are the most common mistakes because they are the most important things to consider when designing applications. If businesses want to create applications that deliver great user experiences, they must take care to avoid these mistakes and look online for User-Experience-Designer questions answers that relate to their troubles.

5 Hosting Options For Your Website

Web hosting refers to the process of making a website accessible via the internet. As part of this process, the website must be stored on a physical server that is housed in a protected location and managed by a hosting company. The server is a specialized computer that was built for the sole purpose of maintaining websites, which it does by ensuring the website’s availability, security, speed, and capacity to update data. There are numerous varieties of hosting, each of which possesses its own individual qualities and capabilities. Let’s take a closer look at them.

Reseller Hosting

Reseller hosting is a hosting solution that entails selling hosting services to individual customers. Due to the extensive level of expertise in information technology that is required, this choice is not appropriate for everyone. However, it is a good way for individuals or businesses to enter the hosting industry and earn a profit by setting their own prices for customers and purchasing services from a supplier at wholesale rates.

Those who are familiar with the technical aspects of hosting and who want to be in control of their own pricing and branding are good candidates for reseller hosting. Before diving headfirst into this kind of hosting, it is important to consider the level of competition in the industry as well as the demand in the market. You also need to have the right skillset in order to be a successful reseller.

Shared Hosting

Shared hosting is by far the most common choice for individuals who own websites. Multiple users share the resources of a single physical server in this form of web hosting. The costs associated with the server’s upkeep are shared among the users. Shared hosting is more cost-effective than any other hosting solution, but the resources that are accessible to each user are restricted. This may become problematic if the website experiences an increase in traffic or has a need for additional resources.

Shared hosting is an excellent choice for personal or small websites that receive little traffic and have fewer resource requirements. To ensure that the website has sufficient resources and is not adversely affected by the traffic and resource usage of other websites that are hosted on the same server, it is essential to choose a hosting provider and a plan with care.

VPS Hosting

Hosting on a virtual private server, also known as VPS, involves the consolidation of several private servers into a single network or physical location. Every virtual private server (VPS) has its own unique configuration options and resources, such as RAM, CPU, disk space, and IP address.

VPS hosting is a better option than shared hosting when it comes to performance because resources are not shared with other users. This makes VPS hosting a good choice for websites that require scalable resources and security measures. Websites that need more resources and control than what shared hosting can offer, but do not yet require the resources or cost of a dedicated server, are good candidates for virtual private server (VPS) hosting.

Dedicated Hosting

Dedicated hosting refers to one server per website. The server can be completely customized to meet the needs of the website owner. This option requires a high level of IT knowledge on the part of the website owner or the hiring of an IT specialist.

Dedicated servers are the most expensive type of hosting option, but they also offer the highest level of control, customization, security, and the quickest loading times. Websites that receive a very high volume of traffic or have resource requirements, as well as those that require full control over the server and all of its resources, are good candidates for hosting on a dedicated server.

Cloud Hosting

Using cloud hosting, websites can be hosted on virtual servers that are supported by cloud computing technologies. Because hardware problems do not impact websites hosted on this platform, the websites benefit from increased stability. Plans for cloud hosting do not come with flat rates or predetermined prices; rather, customers pay only for the resources that they consume. This is an option worth considering for websites that experience varying levels of traffic or have fluctuating resource requirements.

Cloud hosting is suitable for websites that require a hosting solution that is scalable and flexible. However, it is essential to carefully consider the cost and resources required to ensure that the website has sufficient resources and does not exceed the budget.


In this article, we have covered the main hosting options for a website. In order to select the ideal solution, you need to take into account the size of your website, the traffic you anticipate, and your budget.

The Importance of Predictive Maintenance: The Complete Guide

Are you looking to reduce downtime and optimize your maintenance management? The key to success may be in predictive maintenance. Predictive maintenance is a strategy used to monitor and predict the lifespan of equipment or machinery. It focuses on maximizing asset performance by eliminating costly breakdowns and unplanned downtime. Predictive maintenance aims to prevent failures before they occur instead of waiting until something breaks down. This article will discuss the importance of predictive maintenance and how it helps businesses achieve their goals. Let’s get started.

Fewer Machine Failures

The biggest benefit of predictive maintenance is that it helps prevent machine failures. Most companies that involve the use of PdM as a service can reduce their failure rates significantly. This means less downtime, fewer replacements, and more money saved in the long run. It also helps prevent costly repairs and/or replacements, which can be very expensive if they’re not caught before it’s too late.

To ensure there is less downtime, the first step is establishing a baseline of your equipment. This means knowing what they should be performing like and understanding their characteristics. By monitoring the performance of assets regularly, you can spot any abnormalities or unexpected changes quickly, allowing you to take action before it causes serious damage. For instance, noticing a decrease in pressure or temperature can be an indication of something going wrong with the system.

Improved Efficiency

By eliminating unplanned downtime, predictive maintenance also helps increase efficiency. With fewer and shorter downtimes, production will not have to slow down as much, meaning more products can be made quickly. This leads to higher profits and more satisfied customers.

The use of predictive analytics can also help with the scheduling of maintenance activities. With predictive analysis, you can identify the best time to perform inspections or repairs without compromising on their effectiveness. This way, you can optimize your maintenance schedule for improved efficiency in production. Improved efficiency leads to more production, revenue, and profit for your business.

Reduced Maintenance Costs

Every company is looking for ways to reduce costs and optimize its budget. Predictive maintenance is one way to do this. Businesses can drastically reduce their maintenance costs by avoiding unexpected breakdowns and costly repairs. For instance, by using predictive analytics, you can spot potential problems early and take preventive measures before it’s too late.

Furthermore, predictive maintenance helps identify potential issues before they become major ones. This means that you can plan your repairs better and ensure that they are done most cost-effectively. This can be done through predictive analytics, which can help you determine how often each asset should be inspected and repaired.

Increased Productivity

Predictive maintenance is also great for increasing productivity. By avoiding downtime, businesses can keep their production lines running and output steady. Furthermore, by reducing the number of failures, workers can focus more on their work rather than dealing with breakdowns or repairs.

A good example is a business utilizing predictive analytics to identify potential problems. This allows them to take preemptive action and fix any issues before they become major ones. This not only reduces downtime but also makes sure that workers are productive and efficient at all times. Besides, predictive analytics can help with preventive maintenance scheduling, allowing the company to maximize its production and minimize costs.

Increased Asset Lifetime

Predictive maintenance plays an important role in extending the lifetime of assets. By regularly monitoring performance, businesses can identify potential issues before they lead to bigger problems. This way, you can take preventive measures and ensure that your machines last longer than normal.

For instance, some predictive analytics solutions can help you identify when a machine part needs to be replaced or repaired. This allows you to extend the lifetime of your assets, as you won’t have to spend money on unnecessary replacements or repairs. You can also extend the lifetime of entire systems by monitoring their performance and avoiding unexpected breakdowns.

Precise Assets Data

The accurate data gathered through predictive analytics can also be used to improve the performance of your assets. By analyzing the data, you can identify any weak spots and take measures to improve them. This will lead to better performance, increased efficiency, and improved uptime and reliability.

Predictive maintenance can also help businesses make more informed decisions about their assets. By understanding the performance of an asset and its components, you can make better decisions about when to replace or repair them. This will extend their lifetime and save you money in the long run.

Increased ROI

Predictive maintenance can be a great way to increase your return on investment (ROI). By reducing the number of unexpected breakdowns and repairs, businesses can drastically improve their ROI. The accurate data gathered through predictive analytics solutions can also help make better decisions about when to replace or repair assets, which will reduce costs in the long run.

Besides this, predictive maintenance also helps businesses save time. By avoiding unexpected breakdowns, they can keep their production lines running and increase output in a shorter amount of time. This will lead to an improved ROI and better profits in the long run.

Improved Workplace Safety

Predictive maintenance can also help improve workplace safety. By reducing the number of breakdowns, businesses can prevent accidents and injuries in their workplace. The accurate data gathered through predictive analytics solutions can also help identify potential risks and take preventive measures to ensure everyone is safe.

This prevents the company from dealing with costly lawsuits or other legal issues, which can be avoided by implementing predictive maintenance. It also reduces losses caused by unexpected downtime and improves employee morale, leading to a more productive workplace. A good example is when predictive analytics helps identify potential safety risks and businesses take measures to reduce them.

Predictive maintenance can be a great way for businesses to improve their ROI, extend the lifetime of assets, and ensure workplace safety. By regularly monitoring performance and taking preventive measures, businesses can prevent unexpected breakdowns and reduce costs in the long run. Predictive analytics solutions can also help make better decisions about when to replace or repair assets, leading to an improved ROI and better profits. If you have not yet implemented predictive maintenance, now is the time to do so. It can be a great way to keep your assets running smoothly and prevent accidents in the workplace.
