Using the SQLExecutor for Data Quality Management: aka One man's love for the...Safe Software The SQLExecutor is one of FME’s most powerful and flexible transformers. Pivvot maintains a robust internal metadata hierarchy used to support ingestion and curation of thousands of external data sources that must be managed for quality before entering our platform. By using the SQLExecutor, Pivvot can efficiently detect problems and perform analysis before data is extracted from our staging environment, removing the need for rollbacks or cycles waisted on a failed job. This presentation will walk through three distinct examples of how Pivvot uses the SQLExecutor to engage its metadata hierarchy and integrate with its Data Quality Management workflows efficiently and within the source postgres database. Spatial Validation –Validating spatial prerequisites before entering a production environment. Reference Data Validation - Dynamically validate domain-ed columns across any table and multiple columns per table. Practical De-duplication - Removing identical or near-identical well point locations from two distinct source datasets in the same table.

The Future of Product Management in AI ERA.pdf
The Future of Product Management in AI ERA.pdfAlyona Owens Hi, I’m Aly Owens, I have a special pleasure to stand here as over a decade ago I graduated from CityU as an international student with an MBA program. I enjoyed the diversity of the school, ability to work and study, the network that came with being here, and of course the price tag for students here has always been more affordable than most around.
Since then I have worked for major corporations like T-Mobile and Microsoft and many more, and I have founded a startup. I've also been teaching product management to ensure my students save time and money to get to the same level as me faster avoiding popular mistakes. Today as I’ve transitioned to teaching and focusing on the startup, I hear everybody being concerned about Ai stealing their jobs… We’ll talk about it shortly.
But before that, I want to take you back to 1997. One of my favorite movies is “Fifth Element”. It wowed me with futuristic predictions when I was a kid and I’m impressed by the number of these predictions that have already come true. Self-driving cars, video calls and smart TV, personalized ads and identity scanning. Sci-fi movies and books gave us many ideas and some are being implemented as we speak. But we often get ahead of ourselves:
Flying cars,Colonized planets, Human-like AI: not yet, Time travel, Mind-machine neural interfaces for everyone: Only in experimental stages (e.g. Neuralink).
Cyberpunk dystopias: Some vibes (neon signs + inequality + surveillance), but not total dystopia (thankfully).
On the bright side, we predict that the working hours should drop as Ai becomes our helper and there shouldn’t be a need to work 8 hours/day. Nobody knows for sure but we can require that from legislation. Instead of waiting to see what the government and billionaires come up with, I say we should design our own future.
So, we as humans, when we don’t know something - fear takes over. The same thing happened during the industrial revolution. In the Industrial Era, machines didn’t steal jobs—they transformed them but people were scared about their jobs. The AI era is making similar changes except it feels like robots will take the center stage instead of a human. First off, even when it comes to the hottest space in the military - drones, Ai does a fraction of work. AI algorithms enable real-time decision-making, obstacle avoidance, and mission optimization making drones far more autonomous and capable than traditional remote-controlled aircraft. Key technologies include computer vision for object detection, GPS-enhanced navigation, and neural networks for learning and adaptation. But guess what? There are only 2 companies right now that utilize Ai in drones to make autonomous decisions - Skydio and DJI.
From Manual to Auto Searching- FME in the Driver's Seat
From Manual to Auto Searching- FME in the Driver's SeatSafe Software Finding a specific car online can be a time-consuming task, especially when checking multiple dealer websites. A few years ago, I faced this exact problem while searching for a particular vehicle in New Zealand. The local classified platform, Trade Me (similar to eBay), wasn’t yielding any results, so I expanded my search to second-hand dealer sites—only to realise that periodically checking each one was going to be tedious. That’s when I noticed something interesting: many of these websites used the same platform to manage their inventories. Recognising this, I reverse-engineered the platform’s structure and built an FME workspace that automated the search process for me. By integrating API calls and setting up periodic checks, I received real-time email alerts when matching cars were listed. In this presentation, I’ll walk through how I used FME to save hours of manual searching by creating a custom car-finding automation system. While FME can’t buy a car for you—yet—it can certainly help you find the one you’re after!

"Scaling in space and time with Temporal", Andriy Lupa.pdfFwdays Design patterns like Event Sourcing and Event Streaming have long become standards for building real-time analytics systems. However, when the system load becomes nonlinear with fast and often unpredictable spikes, it's crucial to respond quickly in order not to lose real-time operating itself.
In this talk, I’ll share my experience implementing and using a tool like Temporal.io. We'll explore the evolution of our system for maintaining real-time report generation and discuss how we use Temporal both for short-lived pipelines and long-running background tasks.

"Database isolation: how we deal with hundreds of direct connections to the d...Fwdays What can go wrong if you allow each service to access the database directly? In a startup, this seems like a quick and easy solution, but as the system scales, problems appear that no one could have guessed.
In my talk, I'll share Solidgate's experience in transforming its architecture: from the chaos of direct connections to a service-based data access model. I will talk about the transition stages, bottlenecks, and how isolation affected infrastructure support. I will honestly show what worked and what didn't. In short, we will analyze the controversy of this talk.

Database security for PHP
- 1. Database Security for PHP Rohan Faye
- 8. Conclusion
- 9. Introduction Databases: cardinal components of any web based application
- 10. Provides varying dynamic content
- 11. Stores sensitive or secreat information
- 12. PHP cannot protect your database by itself
- 14. Designing databases Create the database
- 15. Grant the privileges in order to allow other users to use it
- 16. Applications should never connect to the database as its owner or a superuser
- 17. Stop intruders from gaining access by assigning limited rights to the database objects
- 18. Designing databases Avoid implementing all the log in the web application
- 19. Use views, triggers or rules Transparency
- 21. Provides insight when debugging problems
- 22. Ability to trace back transactions
- 23. Connecting to database Establish connections over SSL to encrypt client/server communications for increased security
- 24. Use SSH to encrypt the network connection between clients and the database server
- 25. If either of these is used, for a would-be attacker, it will be: Difficult to gain information about your database
- 26. Encrypted storage model SSL/SSH Protects data travelling from client to server
- 27. Does not protect persistent data If attacker gains access, sensitive data can be misused
- 28. Encrypting the data is a good way to mitigate this threat
- 29. Encrypted storage model Create your own encryption package to use it from within your PHP script
- 30. PHP assists you with several extensions like Mcrypt and Mhash
- 31. Script encrypts the data before inserting it into the database, and decrypts it while retrieving
- 32. If raw representation of data is not needed, then can rely upon hashing e.g. crypt() and MD5()
- 33. Before moving further... Real world examples of some major incidents due to a security flaw...
- 34. Incident 1 Date: November 1, 2005
- 35. Attacker: A high school student
- 36. Victim: Taiwanese Information Security magazine's site
- 37. Incident 2 Date: March 29, 2006
- 38. Discovered by: Susam Pal (Security expert)
- 39. Victim: Official Indian government tourism site
- 40. Incident 3 Date: July 19, 2008
- 41. Attacker: m0sted and Amen (Turkish hackers)
- 42. Victim: Kaspersky's malaysian website
- 43. Incident 4 Date: January 20, 2009
- 44. Attacker: Albert Gonzalez and two unnamed Russians
- 45. Victim: Heartland Payment Systems
- 46. Incident 5 Date: October 10, 2009
- 47. Attacker: A turkish crew
- 48. Victim: Federal Bureau of Investigation job site
- 49. Incident 6 Date: December 4, 2009
- 51. Victim: RockYou!
- 52. And many more... All of these incidents comprised a common technique of attack... “ SQL ”
- 53. SQL injection A SQL query is: Not always a trusted command
- 54. Can bypass standard authentication and authorization checks
- 55. May allow access to host operating system level commands
- 56. Direct SQL Command Injection A technique where an attacker can create or alter existing SQL commands to expose hidden data
- 57. Can execute dangerous system level commands on the database host
- 58. Accomplished by the application taking user input and combinig it with static parameters to bulid a SQL query
- 59. Avoiding techniques Never connect to the databse as a superuser or a database owner
- 60. Validate the input – PHP has a wide range of input validating functions
- 61. Perl compatible Regular Expressions support
- 62. Quote each non-numeric user supplied value passed to the databse using database specific string escape function
- 63. Avoiding techniques Do not print out any database specific information by fair means or foul
- 64. Take benifit from logging queries either within your script or by the database itself, if it supports logging Unable to prevent any harmful attempt
- 65. Can be helpful to trace back which application has been circumvented
- 66. Conclusion “A good PHP application doesn't mean to be good looking. It simply wants to be safe...”
- 67. Thank you <?php $references = array( 'The PHP manual', 'Guide to PHP Security', 'Wikipedia', ); ?>
