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).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
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.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
15. LINUX Linux is a Unix-like operating system that was designed to provide personal computer users a free or very low-cost operating system comparable to traditional and usually more expensive Unix systems.
16.
17. Linux was developed by Linux Torvalds at the University of Helsinki in Finland.He started his work in 1991.

33. < /boot > The place where Linux keeps information that it needs when booting up. < /bin > The /bin directory contains the most important programs that the system needs to operate, such as the shells, ls, grep, and other essential things.
34. < /lib > The shared libraries for programs that are dynamically linked. < /sbin, /usr/sbin > Most system administration programs are stored in these directories.
35.
36. The different physical storage devices must be attached to some directory in the file system tree before they can be accessed.
37. This attaching is called mounting, and the directory where the device is attached is called the mount point .
38. < /usr > Contains user applications. /usr is the largest directory on a Linux system. </usr/share> Config files and graphics for many user apps. < /usr/local > This is where you install apps and other files for use on the local machine.
43. </var/spool> - This directory holds files that are queued for some process, like printing.

61. User can get back to the command mode from ex mode by using Enter key.
62. The control can be brought back to the command mode from input mode by using <Esc> key.
63. The actual editing is done in vi editor in the buffer called editor buffer . Following cmds are used to quit from vi editor: 1. zz -last command.Saves the file in change mode and then quits. 2. :w -Just saves or writes the buffer contents on to disk file and remains in cmd mode. Quitting the vi Editor
64. 3. :x -Saves the file in change mode and then quits. 4. :wq - write and quit.Behaves exactly like :x. 5. :q -Quits the vi environment --if change made in editor is already written. --if changes made is not written or saved.It will give suitable message. 6. :q! -Quits the vi env without saving the buffer contents even changes are made.

71.
72. The term cron is derived from the word chronograph.
73. Cron is a system deamon that keeps sleeping most of the time.
80. A crontab may contain one or more files,each corresponding to a command that is to be executed periodically at a specific day, date and time.
81. Minute (0-59) Command to be executed day of week (0-6) 0 being sunday month(1-12) day of month (1-31) Hour (24-h format) Syntax of a crontab line Every line is made up of six fields seperated by a Blank .
82.
83. For example, if a * character appears in the fifth field, then the command mentioned in the line will be executed on all days of the week at the specified time.
84.
85. If neccessary group of numbers can be specified within a single field seperated by commas.
86. Below are two typical crontab lines. 1. 0 0 * * * backup.sh When executed, the above line runs the backup.sh script at midnight everyday .
87. 2. 00,30 09-17 * * 1-5 mail.sh When execute, the above lines runs the mail.sh script on all weekdays-Monday to Friday every half hour between 9 and 17 hours
88.
89. every cmd has to be written in a seperate line having the above format in a seperate file.
90. Then it is submitted to crontab command, as shown below, where cmdfile is the name of the file executed periodically. $crontab cmdfile
