Starting with Spring MVC 2.5, Annotation-Based Controllers became the preferred model for development (the Interface-based Controller hierarchy will be deprecated in Spring 3). This session will teach developers familiar with the old model how to use the new Annotation-based Controllers. This will also provide the basis for writing JSR 286 portlets using Spring 3.

If you want to earn much in web development business, you also need to learn Java web technologies.
Java has de facto standart frameworks such as EJB 3.0, Spring and others that can be bound to them.
But at heart, they all use the similar JSP/Servlet technology and add some layers above them to speed up the development.
You will use them in your daily business but before using them, you must learn the basics and what is going on while using them. Otherwise, you will not be able to find a proper solution to common problems.
This course will make you understand the basics of JSP / servlet technlogies, designing a relational database, DB operations, design patterns, working with other developers,
and let you know the must-do operations in professional projects such as performance increasing, logging errors.
If you want to develop a web-site in a couple of hours without understanding what you are doing, you may go ahead and find other resources. But if you really want to understand what you are doing and learn the theory at the same time, this course will be a great oppurtunity for you. You will develop a real working project. Yow will first write quick and dirty code then you will apply professional patterns one by one while investigating the problems.
You will walk through a real development flow:
1- Write a quick and dirty code for doing the job.
2- You will design database tables and high performance queries
3 - You will apply design patterns to make the code reusable and high performance.
4 - You will beautify the user interface with Javascript and CSS tweaks
5- You will add exception handling, logging mechanism for production environment
6- AT THIS STEP, YOU WILL BE HIRED FOR MUCH MUCH HIGHER SALARIES. BECAUSE YOU ARE A REAL PROFESSIONAL.

In the past I've been building component oriented applications with what I had at hand. Mostly driven by the features available in the Java EE standard to be "portable" and easy to use. Looking back this has been a perfect fit for many customers and applications. With an increasing demand for highly integrated applications which use already available services and processes from all over the place (departmental, central or even cloud services) this approach starts to feel more and more outdated. And this feel does not come from a technology perspective but from all the requirements around it. Having this in mind this post is the starting point of a series of how-to's and short tutorials which aim to showcase some more diverse ways of building (Enterprise Java) applications that fit better into today's requirements and landscapes.

Designing an Investment Portfolio
Designing an investment portfolio may be the most important thing you do in investing. There are tips and insights to make you money but over the long haul profitable investing hinges on hedging investment risk as well as picking winners. Here are a few insights into designing an investment portfolio.
Matching Portfolio Risk to the Investor
We have often noted that as an investor ages he or she will commonly want to move to dividend stocks instead of riskier investment. Business Insider gives an example of analyzing the portfolio of a retiree for risk.
What’s one trademark of a poorly designed investment portfolio? The answer is a portfolio whose risk character is incompatible with the risk character of its owner.
Frequently, these risk incompatibilities are camouflaged by a hot stock market. But when the market reverses and begins to fall like it has lately, the problems of investment portfolios with unsuitable risk levels becomes apparent.
Factors to consider are cost, diversification, risk, tax efficiency and long term performance. You may be invested in a fund that pays good returns but those returns are largely eaten up by fees and commissions. If you were invested heavily in big oil you lost heavily when the price of oil fell. Diversification across various market sectors is good. Tax free or tax advantaged investments are good if you are still in your earning years but less important as you retire. Risk and long term performance are closely related. As the author says when the market is hot all stocks look good but when it falls only strong companies hold their value. If you would like to sleep well at night load up on long term strong performers.
Unexpected Outcomes
Sometimes strategies for designing an investment portfolio do not work out as expected. The New York Times writes about investment strategies mean to lessen volatility and how they may not have worked as expected.
http://www.profitableinvestingtips.com/stock-investing/diversify-your-investment-portfolio
Diversify Your Investment Portfolio
Diversification is a means of reducing risk and increasing opportunity in investing. The chances of having a stock in your portfolio rise significantly in price goes up when you have five well-chosen stocks instead of one. The chances of losing all of your investment capital also go down when you diversify your investment portfolio among several stocks in several market sectors. Likewise, if a part of your investments is in property, a part is in stocks, a part is in bonds, and a part is in offshore investments you can reduce risk and increase the opportunity for profits. When suggesting offshore investment opportunities we wrote about Three Good Offshore Investment Ideas, for example.
Diversify Your Investment Portfolio to Gain Variety and Opportunity
When you diversify your investment portfolio you invest in a variety of assets. Because the value of each investment does not go up or down in perfect harmony, diversification averages out risk, as well as gain. To the extent that one is looking to a big gainer, having more stocks, real estate, or other assets may serve to increase the odds of success. In their book A Random Walk Down Wall Street the authors note that the best return in stocks is often a basket of about forty small cap stocks. These stocks are priced low because of the risk inherent in small companies. However, if you diversify your investment portfolio with a large number of these stocks, you increase the chances of finding a huge winner which will negate the effects on the portfolio of a handful of losers.

Trading Strategies
Trading Strategies for Playing the Stock Market
Trading strategies discussed in this article include swing trading and day trading. Both are very similar but the main difference between theses two strategies is the time frame in which stocks are bought and held. In today’s article we will discuss both of these strategies as well as the advantages and disadvantages of each.
Swing trading typically involves a smaller position size than when day trading stock online. Additionally, swing traders will typically hold onto stocks for a few days to several weeks and then trade the stock on the basis of its intra-week or intra-month movements. Stop loss orders are placed wider than when day trading as well. When determining exits when swing trading there are rules that every trader should follow. It is very important that the trading strategies as well as the trading rules are understood before placing trades in this fashion. For instance, if the prior day’s low is taken out on the breakout day, or the high for shorts, then the trader should exit the trade. Also, once a trade is held overnight, a stop loss order should be placed no further away than below the recent consolidation area. A move beneath it would indicate a failure.
Swing trading stocks has its advantages and disadvantages as all trading strategies do. Some advantages include that swing traders can place fewer trades, therefore requiring fewer commissions and less chance of making a mistake. Additionally this type of stock trading provides the ability for successful traders to catch more significant multi-day profitable traders. A disadvantage to swing trading is the fact that the higher profit targets come with higher risk per trade. There is also overnight exposure that cannot be predicted.
Day trading stocks requires a larger positions size since you are looking for a smaller move within a short time frame. Unlike swing traders, a day trader may trade a few times per day or more! There are also rules with day trading that every investor should follow. For instance, they should always keep their profit objective at least 3 times greater than what they are willing to risk. Also, day traders should allow no more than 1% move against them from the entry point. There are many more trading strategies and rules when day trading that investors should learn in addition to these two rules.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
