DNS - Domain Name System
DNS - Domain Name SystemPeter R. Egli Overview of the Domain Name System (DNS).
In the early days of the Internet, hosts had a fixed IP address.
Reaching a host required to know its numeric IP address.
With the growing number of hosts this scheme became quickly awkward and difficult to use.
DNS was introduced to give hosts human readable names that would be translated into a numeric IP addresses on the fly when a requesting host tried to reach another host.
To facilitate a distributed administration of the domain names, a hierarchic scheme was introduced where responsibility to manage domain names is delegated to organizations which can further delegate management of sub-domains.
Due to its importance in the operation of the Internet, domain name servers are usually operated redundantly. The databases of both servers are periodically synchronized.
Linux command ppt
Linux command pptkalyanineve Here are the key differences between relative and absolute paths in Linux:
- Relative paths specify a location relative to the current working directory, while absolute paths specify a location from the root directory.
- Relative paths start from the current directory, denoted by a period (.). Absolute paths always start from the root directory, denoted by a forward slash (/).
- Relative paths are dependent on the current working directory and may change if the working directory changes. Absolute paths will always refer to the same location regardless of current working directory.
- Examples:

C++ amp on linux
C++ amp on linuxMiller Lee Miller Lee discusses C++ Accelerated Massive Parallelism (C++ AMP) which provides a simpler programming model for GPU computing compared to CUDA and OpenCL. C++ AMP models GPU data as C++ containers and kernels as C++ lambdas. The MCW C++ AMP (CLAMP) compiler translates C++ AMP code to OpenCL, generating OpenCL C code for the device and host code for execution. While C++ AMP code is more concise than OpenCL, its performance depends on the compiler and runtime support.

Drush for humans - SANDcamp 2013
Drush for humans - SANDcamp 2013Jon Peck Learn how site building and maintenance can benefit from Drush, the Drupal command line shell and scripting interface. Join Jon Peck, author of the lynda.com course Simplified Drupal Sites with Drush as he describes what Drush is, demonstrates how to install it, and how to use it effectively for everyday tasks. Drush is a fantastic daily-use tool without the overhead of the full Drupal GUI and bootstrap, but it has some drawbacks in terms of approachability. The documentation for drush, while thorough and improving, can be intimidating and obtuse for people who don’t live, breathe and code Drupal. drush.org the home page is an example of this; it’s a very useful source of information, but it’s literally dozens of commands and all their arguments displayed on one page. Where should a new Drush user start?

Slack like a pro: strategies for 10x engineering teams
Slack like a pro: strategies for 10x engineering teamsNacho Cougil You know Slack, right? It's that tool that some of us have known for the amount of "noise" it generates per second (and that many of us mute as soon as we install it 😅).
But, do you really know it? Do you know how to use it to get the most out of it? Are you sure 🤔? Are you tired of the amount of messages you have to reply to? Are you worried about the hundred conversations you have open? Or are you unaware of changes in projects relevant to your team? Would you like to automate tasks but don't know how to do so?
In this session, I'll try to share how using Slack can help you to be more productive, not only for you but for your colleagues and how that can help you to be much more efficient... and live more relaxed 😉.
If you thought that our work was based (only) on writing code, ... I'm sorry to tell you, but the truth is that it's not 😅. What's more, in the fast-paced world we live in, where so many things change at an accelerated speed, communication is key, and if you use Slack, you should learn to make the most of it.

DevOpsDays SLC - Platform Engineers are Product Managers.pptxJustin Reock Platform Engineers are Product Managers: 10x Your Developer Experience
Discover how adopting this mindset can transform your platform engineering efforts into a high-impact, developer-centric initiative that empowers your teams and drives organizational success.
Platform engineering has emerged as a critical function that serves as the backbone for engineering teams, providing the tools and capabilities necessary to accelerate delivery. But to truly maximize their impact, platform engineers should embrace a product management mindset. When thinking like product managers, platform engineers better understand their internal customers' needs, prioritize features, and deliver a seamless developer experience that can 10x an engineering team’s productivity.
In this session, Justin Reock, Deputy CTO at DX (getdx.com), will demonstrate that platform engineers are, in fact, product managers for their internal developer customers. By treating the platform as an internally delivered product, and holding it to the same standard and rollout as any product, teams significantly accelerate the successful adoption of developer experience and platform engineering initiatives.

Bepents tech services - a premier cybersecurity consulting firm
Bepents tech services - a premier cybersecurity consulting firmBenard76 Introduction
Bepents Tech Services is a premier cybersecurity consulting firm dedicated to protecting digital infrastructure, data, and business continuity. We partner with organizations of all sizes to defend against today’s evolving cyber threats through expert testing, strategic advisory, and managed services.
🔎 Why You Need us
Cyberattacks are no longer a question of “if”—they are a question of “when.” Businesses of all sizes are under constant threat from ransomware, data breaches, phishing attacks, insider threats, and targeted exploits. While most companies focus on growth and operations, security is often overlooked—until it’s too late.
At Bepents Tech, we bridge that gap by being your trusted cybersecurity partner.
🚨 Real-World Threats. Real-Time Defense.
Sophisticated Attackers: Hackers now use advanced tools and techniques to evade detection. Off-the-shelf antivirus isn’t enough.
Human Error: Over 90% of breaches involve employee mistakes. We help build a "human firewall" through training and simulations.
Exposed APIs & Apps: Modern businesses rely heavily on web and mobile apps. We find hidden vulnerabilities before attackers do.
Cloud Misconfigurations: Cloud platforms like AWS and Azure are powerful but complex—and one misstep can expose your entire infrastructure.
💡 What Sets Us Apart
Hands-On Experts: Our team includes certified ethical hackers (OSCP, CEH), cloud architects, red teamers, and security engineers with real-world breach response experience.
Custom, Not Cookie-Cutter: We don’t offer generic solutions. Every engagement is tailored to your environment, risk profile, and industry.
End-to-End Support: From proactive testing to incident response, we support your full cybersecurity lifecycle.
Business-Aligned Security: We help you balance protection with performance—so security becomes a business enabler, not a roadblock.
📊 Risk is Expensive. Prevention is Profitable.
A single data breach costs businesses an average of $4.45 million (IBM, 2023).
Regulatory fines, loss of trust, downtime, and legal exposure can cripple your reputation.
Investing in cybersecurity isn’t just a technical decision—it’s a business strategy.
🔐 When You Choose Bepents Tech, You Get:
Peace of Mind – We monitor, detect, and respond before damage occurs.
Resilience – Your systems, apps, cloud, and team will be ready to withstand real attacks.
Confidence – You’ll meet compliance mandates and pass audits without stress.
Expert Guidance – Our team becomes an extension of yours, keeping you ahead of the threat curve.
Security isn’t a product. It’s a partnership.
Let Bepents tech be your shield in a world full of cyber threats.
🌍 Our Clientele
At Bepents Tech Services, we’ve earned the trust of organizations across industries by delivering high-impact cybersecurity, performance engineering, and strategic consulting.
