Today the average website loads more than 1.5MB of assets including images, scripts and other external data. This causes frustrating delays for site visitors and often leads to abandoned visits. As mobile data is expensive in many developing countries, cost for each page view is also significant consideration.
A number of tools exist to help optimize sites and we’ll introduce and setup a private instance of the popular WebPagetest tool. WPT covers load time, web server compression and caching settings, and timeline based screen shots through the duration of the page load.

Performance testing with VSTs on- and off-premisesJeff Bramwell
Many of us have been there before... You deploy your brand new web site to production, you know, the one that's going to make your company rich and you famous, and just as you're about to hit a thousand users, the site comes crashing down! If you haven?t experienced this, chances are you know someone who has.If you're building web apps and services for your organization you know how important it is to ensure those services are always up and running. While many of us go through great lengths to ensure we are testing the functionality of our systems we do not always take performance or system load into account.Visual Studio Team Services (VSTS) provides multiple options and avenues for enabling performance and load testing for your systems. For example, did you know that VSTS also supports JMeter tests? With VSTS you can even run performance tests using on-premises servers in your own data center. This talk will give you an overview of the performance and load testing capabilities of VSTS. If you haven't looked at the load testing features of VSTS lately, you should definitely check out this talk!
Scaling wix with microservices and multi cloud - 2015Aviran Mordo
Many small startups build their systems on top of a traditional toolset like Tomcat, Hibernate, and MySQL. These systems are used because they facilitate easy development and fast progress, but many of them are monolithic and have limited scalability. So as a startup grows, the team is confronted with the problem of how to evolve the system and make it scalable. Facing the same dilemma, Wix.com grew from 0 to 70 million users in just a few years. Facing some interesting challenges, like performance and availability. Traditional performance solutions, such as caching, would not help due to a very long tail problem which causes caching to be highly inefficient. And because every minute of downtime means customers lose money, the product needed to have near 100% availability. Solving these issues required some interesting and out-of-the-box thinking, and this talk will discuss some of these strategies: building a highly preformant, highly available and highly scalable system; and leveraging microservices architecture and multi-cloud platforms to help build a very efficient and cost-effective system.
Team Foundation Server (TFS) has been around for over a decade now(!) and Visual Studio Team Services (VSTS) has been around for several years. One of the reasons TFS/VSTS has been successful for so many years lies in the extensibility model provided by Microsoft. VSTS/TFS provides a large set of capabilities out of the box but no platform can be everything to everyone. With a rich extensibility model, however, you can shape, mold and extend VSTS/TFS to suit your organization's specific needs. In this talk, we will cover the rich set of REST APIs that Microsoft provides for extending VSTS/TFS. We will take a look at the capabilities that are currently available as well as address some of the features that have yet to make it into the REST APIs. We'll take a look at some code examples and patterns that make it easy to integrate with the REST APIs so you can quickly get up and running with your own customizations.
A discussion of three types of ember addons: one that makes components available to consuming apps, one that modifies the asset pipeline of consuming app, and one that adds a new command to ember-cli
This is my presentation about CFWheels at CFObjective ANZ, November 2010, Melbourne, Australia.
ColdFusion on Wheels (CFWheels), is an elegant framework inspired by Ruby on Rails.
Have you ever customized VSTS/TFS and made it do something really awesome that wasn't possible in the out of the box experience? Have you ever created something so cool that you'd like to share it? Maybe even monetize it? Maybe you have an idea on how to better the experience in VSTS/TFS but don't know where to start? In this talk, we'll discuss the various ways you can make use of custom extensions in VSTS/TFS. We'll talk about what can be customized within an extension and what can't We'll go over some patterns for getting an extension up and running quickly as well as some tips and tricks on debugging extensions and getting them deployed.

Load testing with Visual Studio and Azure - Andrew SiemerAndrew Siemer
In this presentation we will look at what web performance testing is and the various types of testing that can be performed. We will then dig into Visual Studio 2013 Ultimate to see that the Visual Studio platform is now a real contender in performance testing automation. And we will see how the Visual Studio integration with Visual Studio Online and Azure can take your web performance tests and spin up impressive load tests in a truly useful way.
Why test automation is getting more difficult, and what can be done about it. This slides are from a presentation by Group Director, Product Management at TestPlant, Gordon McKeown, which was presented at the Northern Lights conference in Manchester in April 2016.
The network is crucial to deliver a great user experience for your application. As web pages bulk up with ads, scripts and media from remote networks it becomes harder to measure and optimize performance. ThousandEyes helps you quickly determine whether your app, your network or another network is at fault.
In these slides, we share how to:
* Measure page load time by object and network.
* Detect performance issues by third parties, such as CDNs or ad networks.
* Set up and script robust web transactions.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

“The Speed Index is the average
time at which visible parts of
the page are displayed. It is
expressed in milliseconds and
dependent on size of the view
port.”
- webpagetest.org
29. Webpage test
• Public website that you can request a
test for any publicly available website
• Requests limited per day
• Can test from locations around the
world and from within providers such
as Amazon Web Services (AWS)
• Provides results from a single test or
you can aggregate from multiple runs
