File upload php
The PHP script uses the HTTP_Upload class to handle multiple file uploads from an HTML form. It creates 5 instances of the HTTP_Upload class, one for each file upload field. It checks that the files were uploaded successfully and moves them to the destination folder. Any errors are displayed to the user.
<?php
// Destination folder for uploaded files
$destination_folder = '/homework_submissions';
// Loop through each file upload field
for($i=1; $i<=5; $i++) {
// Create HTTP_Upload instance
$
Uploading a file with php
This document discusses how to upload files with PHP. It explains that a form with enctype="multipart/form-data" is needed for users to select a file to upload. The file information is stored in the $_FILES superglobal array. The PHP move_uploaded_file() function can then be used to move the temporary file to its permanent location. Validation checks like file size and type limits should be added to prevent potential risks from file uploads.

- Retrieving and manipulating database records through functions like SELECT, adding new records, etc.
The document provides code examples for connecting to Postgres with Perl, executing queries to retrieve data, and manipulating the database through operations like inserting new records. It focuses on
File Upload
1) File uploads in PHP require configuring php.ini settings like enabling file uploads and setting temporary storage directories with correct permissions.
2) Forms for file uploads need to use POST with multipart/form-data encoding and include file input fields and hidden fields.
3) PHP stores uploaded files in the $_FILES array, including the temporary filename, size, type, and original name, which can then be processed and moved to a permanent location.
DNS resolution
DNS resolution is the process of converting a domain name to an IP address. It works similarly to looking up a phone number in a phone book by hierarchy. All devices on the internet communicate through IP addresses, so DNS resolution occurs any time a website or email is accessed to translate the domain name into the IP address needed to connect. Reverse DNS resolution works in the opposite direction to convert an IP address into its associated domain name.
Hadoop operations basic
This document provides an overview of Hadoop, including its architecture, installation, configuration, and commands. It describes the challenges of large-scale data that Hadoop addresses through distributed processing and storage across clusters. The key components of Hadoop are HDFS for storage and MapReduce for distributed processing. HDFS stores data across clusters and provides fault tolerance through replication, while MapReduce allows parallel processing of large datasets through a map and reduce programming model. The document also outlines how to install and configure Hadoop in pseudo-distributed and fully distributed modes.

Open LDAP vs. Active Directory
This document compares the directory services OpenLDAP and Active Directory (AD). It finds that OpenLDAP supports more LDAP standards, runs on more platforms, and has significantly better performance than AD, particularly for large user databases. While AD may be easier to use initially, OpenLDAP provides more flexibility, extensibility, and lacks the limitations of AD around schema, data access, indexing, and caching. In conclusion, the document states that while AD excels as a proprietary directory, OpenLDAP is a true standards-compliant LDAP directory.
AD & LDAP
Active Directory is a common interface for organizing and maintaining information related to resources connected to a variety of network directories.
Lightweight Directory Access Protocol (LDAP) is an Internet protocol used to access information directories.
A directory service is a distributed database application designed to manage the entries and attributes in a directory.

Challenges of container configuration
Introducing containers into your infrastructure brings new capabilities, but also new challenges, in particular around configuration. This talk will take a look under the hood at some of those operational challenges including:
* The difference between runtime and build-time configuration, and the importance of relating the two together.
* Configuration drift, immutable mental models and mutable container file systems.
* Who configures the orchestrators?
* Emergent vs. model driven configuration.
In the process we will identify some common problems and talk about potential solutions.

Architecting cloud
The document discusses various stages in architecting an application for the cloud as it grows in scale and complexity.
Stage 1 involves a simple architecture suitable for startups with low overhead. Stage 2 adds redundancy as the business grows. Stage 3 requires the addition of load balancers and more servers as publicity increases load. Stage 4 requires database replication and partitioning as single databases can no longer handle the load. Later stages involve rearchitecting the application and databases to support further scaling through techniques like data partitioning, database clustering, and optimizing code and resources.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

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).
