I benchmark effettuati su molti framework PHP negli ultimi mesi mostrano una netta inferiorità di Symfony2 rispetto agli altri. In questo talk parleremo del perchè i benchmark sulla velocità non rappresentano il vero valore di Symfony2, mentre lo sono la flessibiità, la modularità e l'aderenza a degli standard. Parleremo delle caratteristiche che rendono questo framework uno dei più usati in ambito PHP, anche solo considerando quanti altri framework stanno integrando parti di esso. Infine, parleremo di come questo framework metta nelle mani di chi lo utilizza strumenti molto potenti (e a volte complessi) e lasci la responsabilità di come utilizzarli a noi sviluppatori. In questo momento vale come mai prima la massima 'da grande potere deriva grande responsabilità'.

Last year I presented a speech on how we were trying to solve some of Ideato’s organizational problems. This year I’ll talk about what we achieved and how, and in which direction we are going on. This speech will focus on how we are trying to create a self-sufficient and self-organized team. I’ll talk about what ideato is doing to get the most applying eXtreme Programming principles and values. This speech will focus on clients involvement and sustainable pace.

Now, those stark lines are blurring as both sides are discovering they have content that’s relevant to the other. Join Tammy Rutherford as she walks through the pros and cons of corporate and higher ed collaborating. And the challenges of these different technology platforms working together for a brighter future.

Dubai, known for its towering skyscrapers, luxurious lifestyle, and relentless pursuit of innovation, often finds itself in the global spotlight. However, amidst the glitz and glamour, the emirate faces its own set of challenges, including the occasional threat of flooding. In recent years, Dubai has experienced sporadic but significant floods, disrupting normalcy and posing unique challenges to its infrastructure. Among the critical nodes in this bustling metropolis is the Dubai International Airport, a vital hub connecting the world. This article delves into the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

In the thrilling conclusion to 2023, ransomware groups had a banner year, really outdoing themselves in the "make everyone's life miserable" department. LockBit 3.0 took gold in the hacking olympics, followed by the plucky upstarts Clop and ALPHV/BlackCat. Apparently, 48% of organizations were feeling left out and decided to get in on the cyber attack action. Business services won the "most likely to get digitally mugged" award, with education and retail nipping at their heels. Hackers expanded their repertoire beyond boring old encryption to the much more exciting world of extortion. The US, UK and Canada took top honors in the "countries most likely to pay up" category. Bitcoins were the currency of choice for discerning hackers, because who doesn't love untraceable money?

The action of the next cyber saga takes place in the mystical lands of the Asia-Pacific region, where the main characters began their digital activities in the middle of 2021 and qualitatively strengthened it in 2022. Corporate espionage, document theft, audio recordings, and data leaks from messaging platforms were all a matter of one day for Dark Pink. Their geographical focus may have started in the Asia-Pacific region, but their ambitions knew no bounds, targeting a European government ministry in a bold move to expand their portfolio. Their victim profile was as diverse as a UN meeting, targeting military organizations, government agencies, and even a religious organization. Because discrimination is not a fashionable agenda. In the world of cybercrime, they serve as a reminder that sometimes the most serious threats come in the most unassuming packages with a pink bow.
