Goodbye Windows 11: Make Way for Nitrux Linux 3.5.0!SOFTTECHHUB
As the digital landscape continually evolves, operating systems play a critical role in shaping user experiences and productivity. The launch of Nitrux Linux 3.5.0 marks a significant milestone, offering a robust alternative to traditional systems such as Windows 11. This article delves into the essence of Nitrux Linux 3.5.0, exploring its unique features, advantages, and how it stands as a compelling choice for both casual users and tech enthusiasts.
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.

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).

An embedded product uses a microprocessor or microcontroller to do
one task only.
In an embedded system, there is only one application software that is
typically burned into ROM.

21. Pins of 8051Pins of 8051 (( 2/42/4 ))
RST ( pin 9 ): reset
– It is an input pin and is active high ( normally low ) .
The high pulse must be high at least 2 machine cycles.
– It is a power-on reset.
Upon applying a high pulse to RST, the
microcontroller will reset and all values in registers
will be lost.
Reset values of some 8051 registers
23. Pins of 8051Pins of 8051 (( 3/43/4 ))
/EA ( pin 31 ): external access
– There is no on-chip ROM in 8031 and 8032 .
– The /EA pin is connected to GND to indicate the code is
stored externally.
– /PSEN & ALE are used for external ROM.
– For 8051, /EA pin is connected to Vcc.
– “/” means active low.
/PSEN ( pin 29 ): program store enable
– This is an output pin and is connected to the OE pin of the
ROM.
24. Pins of 8051Pins of 8051 (( 4/44/4 ))
ALE ( pin 30 ): address latch enable
– It is an output pin and is active high.
– 8051 port 0 provides both address and data.
– The ALE pin is used for de-multiplexing the address
and data by connecting to the G pin of the 74LS373
latch.
I/O port pins
– The four ports P0, P1, P2, and P3.
– Each port uses 8 pins.
– All I/O pins are bi-directional..
25. Pins of I/O PortPins of I/O Port
The 8051 has four I/O ports
– Port 0 ( pins 32-39 ): P0 ( P0.0 ~ P0.7 )
– Port 1 ( pins 1-8 ) : P1 ( P1.0 ~ P1.7 )
– Port 2 ( pins 21-28 ): P2 ( P2.0 ~ P2.7 )
– Port 3 ( pins 10-17 ): P3 ( P3.0 ~ P3.7 )
– Each port has 8 pins.
Named P0.X ( X=0,1,...,7 ) , P1.X, P2.X, P3.X
Ex : P0.0 is the bit 0 ( LSB ) of P0
Ex : P0.7 is the bit 7 ( MSB ) of P0
These 8 bits form a byte.
Each port can be used as input or output (bi-direction).
26. Hardware Structure of I/O PinHardware Structure of I/O Pin
Each pin of I/O ports
– Internal CPU bus : communicate with CPU
– A D latch store the value of this pin
D latch is controlled by “Write to latch”
– Write to latch = 1 : write data into the D latch
– 2 Tri-state buffer :
TB1: controlled by “Read pin”
– Read pin = 1 : really read the data present at the pin
TB2: controlled by “Read latch”
– Read latch = 1 : read value from internal latch
– A transistor M1 gate
Gate=0: open
Gate=1: close
