The potential applications for useClickOutside are endless. It is particularly useful when implementing modal windows, dropdown menus, or any element that should be closed when a user interacts with anything outside of it. By incorporating useClickOutside, you can enhance the user experience by providing intuitive and efficient interactions.
Referential transparency, a key concept in functional programming, is often associated with more reliable, easier to test, and safer software. This term refers to a principle in which a function, given the same input, will always produce the same output without producing any side effects.
In the real world of software development, side effects are inevitable. Programs are rarely useful unless they interact with the outside world. This interaction could be reading from or writing to the console, making network requests, querying a database, or modifying a variable.
Yet, despite the necessity of side effects, they introduce risks and complexities. Programs with side effects are harder to test, harder to reason about, and more prone to bugs. They can also make the system as a whole more difficult to understand and maintain, due to hidden dependencies between components.
Enter referential transparency - a concept that means a function, given the same input, will always provide the same output, without creating any side effects. A function that adheres to this principle doesn't read any global state or change any state outside of its scope. The result is code that is more predictable and easier to reason about.
In terms of software safety and reliability, the absence of side effects is not enough. Programs should also be free from external influence - their results should only depend on their arguments. That is, programs should not read data from the console, a file, network, database, or even system variables.

These platforms have redefined how audiences access and consume content, introducing cutting-edge technologies and innovative features that have revolutionized the entertainment industry.
Embracing Augmented Reality (AR) and Virtual Reality (VR)
In 2023, VOD OTT platforms have embraced AR and VR technologies to provide viewers with immersive and interactive experiences. Users can now step into virtual worlds, interact with characters, and actively participate in the content they are watching, transcending the boundaries of traditional passive viewing.
Imagine exploring an ancient civilization through the eyes of a protagonist, feeling the thrill of an adrenaline-pumping car chase, or even interacting with virtual avatars of celebrities and influencers. The integration of AR and VR into VOD OTT platforms has ushered in a new era of interactive and experiential entertainment.
Personalization: The Heart of the VOD Experience
Powered by advanced artificial intelligence (AI), VOD OTT platforms have taken personalization to new heights. By analyzing user behavior, preferences, and viewing habits, these platforms deliver tailor-made content recommendations, ensuring that viewers find exactly what they love without extensive searching.
This level of personalization ensures that users are presented with content that resonates with their tastes, creating a seamless and enjoyable content discovery experience. By removing the need for extensive searching, VOD OTT platforms have become the go-to destination for viewers seeking highly relevant and engaging content.

Let’s imagine you need access to the real-time data of some smart contracts on Ethereum (or Polygon, BSC, etc.) like Uniswap or even PEPE coin to analyze its data using the standard data scientist/analyst tools: Python, Pandas, Matplotlib, etc. In this tutorial, I’ll show you more sophisticated data access tools that are more like a surgical scalpel (The Graph subgraphs) than a well-known Swiss knife (RPC node access) or hammer (ready-to-use APIs). I hope my metaphors don’t scare you 😅.
Most novice web designers at the beginning of their journey still in the courses hear such a concept as modular grid, and wonder what it is and how to properly customize and use this tool.
From personal experience, I know that in many courses with titles "web designer from zero to pro" or " IU / UX designer in a month" this topic is either skipped, or give instructions, where they say everywhere to use a grid of 12 columns with margins of 80 to 100 pixels. And, as a result, it turns out that after taking these gore courses, a person sees beautiful works, thinks to repeat them, but the grid does not work, and the student, simply, does the work without a grid and completely forgets about it.
That's why I want to help beginners to understand this really voluminous issue.
CTO: Balancing Leadership and Architecture.
As a CTO, effective leadership goes beyond technical architecture. Conducting regular performance reviews is a crucial part of managing teams.
Note: The performance review schedule may vary depending on the specific
company's policies and guidelines.
For early-stage startups, lacking CTO expertise in conducting performance reviews is common. In my experience, I've tailored grades to encompass all aspects of professional iOS development, keeping project-specific needs in mind. Being the first in the team can offer significant growth opportunities. However, acknowledging any lack of people management skills and compensating through continuous growth is essential.
I've compiled my insights on structuring the iOS development department, conducting performance reviews, and most importantly, emphasizing the significant distinctions between developers' levels based on well-defined criteria.

Wie ich ein einfaches Monitoring von Kanälen mit Benachrichtigungen an Slack ohne Erfahrung gemacht habe
Arbeiten im technischen Support brachte zusätzlich zu allen Aufgaben die Pflicht mit sich, die Kommunikationskanäle zu überwachen. Dies wurde über den Grafana-Dienst realisiert, der die erforderlichen Metriken aus Zabbix bezog. Da die Art der Arbeit jedoch bedeutete, dass man nicht immer an seinem Arbeitsplatz sitzt, kam mir die Idee, dies ein wenig zu automatisieren und Benachrichtigungen auf das Telefon oder zum Beispiel in einen Messenger zu erhalten, falls ein Kommunikationskanal ausfällt. Allerdings hatte ich keinen Zugriff auf das Zabbix-System und auch keinen erweiterten Zugriff auf Grafana.
LeetCode 2790 (Hard). Maximum Number of Groups With Increasing Length. Solution of the day. O(N logN). Math
Simple Swift Math Solution.
Time complexity: O(N logN).
time complexity of this solution is dominated by the sorting step, making it O(N logN), where N is the length of the input array usageLimits. The rest of the operations involve simple arithmetic and comparisons, which take linear time. Therefore, the overall time complexity of the function is O(NlogN).

Against the backdrop of a sharp decline in venture investments in various traditional industries (this is clearly related to the global economic situation), but against the backdrop of certain upheavals in the crypto industry, the question arises of a driver that can become one of the «pillars» of the development of a decentralized industry.
Today, it becomes quite obvious that the situation with web3 technology is becoming similar to the situation with programmatic advertising 10-12 years ago. When programmatic-ads just started, the major market players were not very optimistic - it was much easier for them to follow the well-known paths with chains of publishers and agencies. However, once programmatic got rid of the «childhood diseases» and became simple in use, effective in attracting customers, it has taken a dominant position in the modern advertising market - providing precise targeting and cost reduction. The situation with web3 is similar - all publishers ideally want to have systems for lifetime tracking of customer achievements (that is, Soul Bound tokens in web3), theoretically stable decentralized data storage systems that cannot be broken through a simple server attack, real users’ ownership for his content, as well as simple cross-border payment systems that have built-in algorithms for calculating all duties and taxes. Sounds like a perfect world, but even Amazon doesn't do that yet. Why?
The problem is the web3 entry point, which is difficult for users. As soon as they start talking about opening a crypto wallet, about 12 phrases as a backup, most users interrupt the onboarding process and immediately leave the site. This is obvious - over the decades of the development of the digital market, users have become accustomed to facilitating and simplifying systems for interacting with the site. One-click registration, effective convenient UI, visibility and the «metro principle», where the client is led by the hand – this is modern digital progress. And here some 12 phrases are offered, incomprehensible tokens - and, most importantly, why? So, it turns out that a self-sufficient audience of geeks or really advanced users revolves around web3, which is growing weakly.
