Here are the step-by-step workings:
1) $s0 contains the binary value: 00001010 (which is the decimal value 10)
2) sll shifts the bits in $s0 left by 4 positions:
00001010 (original value of $s0)
00101000 (value after shifting left by 4 bits)
3) The result is stored in $t2
So the value of $t2 after the operation is 00001010 << 4 = 01010000 = decimal 80
Therefore, the value of $t2 is 80.

As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered

ISA and uArch
• Instruction Set Architecture (ISA) is a precise definition of
computer instructions, features and mechanism
(procedures, interrupt/exception handler, etc.) and also
some structures (registers, memory, etc.)
• It can be thought as an agreement between a programmer
and an engineer:
• It’s all programmer needs to program machine.
• It’s all hardware designer needs to design machine.
• Microarchitecture (uArch, implementation) is an
organization and features of Hardware that executes
instructions and support features defined in the ISA.

ISA and uArch
• What a typical ISA defines
• Data Formats. (Integer, Floating Point, Vector/Packed)
• Instructions. (Operations, encoding, etc.)
• Registers and Memory Organization.
• Interrupts, exceptions, and traps.
• Implementation-Dependent Features. (Memory control, custom
features.)
• What a typical uArch defines (not included into ISA)
• Memory hierarchy organization (caches, buses, etc.)
• Pipeline (forwarding, branch prediction, etc.)
• Out-of-order executions … and many others.

Example: MIPS
• An example of a RISC processor.
• Designed for easy programming and implementation.
• Short and simple, but fast instructions → programs are larger than others,
but run faster.
• The main aim was to take advantages of pipelined execution
• Pipeline was not specified in ISA, but ISA developers tried to simplify its
implementation in uArch.
• Implementations:
• The first one is R2000 (1986)
• Later: R3000A (PlayStation), R4000 (PSP), R5900 (PlayStation 2), etc.
• Currently it is widely used in embedded systems.
• One moment MIPS seemed to be overcome Intel IA-32, but it didn’t
happen because Intel’s uArch was significantly better and could
compensate the drawback of IA-32.

Data Formats
• In the memory all including data and program code is
presented as binary numbers:
• Data representation:
• Sizes: 8-b Bytes, 16-b Half words, 32-b words and 64-b double
words (not considered in this course)
• Formats: signed/unsigned integer, signed/unsigned floating point
(not considered in this course)

Memory addressing
• Memory (MEM) is a concept of a storage for programs and their
data
• It is a part of programmer-visible machine state (fully controlled by a
programmer)
• It can be though as an linear array of Bytes.
• Data can be read or written into this storage using an index which is
called memory address.
• The size of the memory is equal to 2 𝑁 Bytes, where N is the maximal
number of bits that can be encoded in a memory address.
• Usually, there is no separate memory for code or data. They are
stored together in the same space.

Big and Little Endian
• Historically numbers are being written from the right to the left
(the most significant digit is on the right):
• However, we used to enumerate elements in an array (and
most other things) from the left to the right:
• The question: if we put an value of two bytes (e.g. 256) at the
beginning of the array where the most significant byte will be?
In element 0 or element 1?

Registers
• Registers is fast, but small (vs. memory) storage for data
• A great amount of registers are included into programmer-visible
machine state (fully controlled by a programmer):
• Program counter (PC) stores the address of the currently executed
instruction
• General Purpose Registers (GPR) is used to store intermediate
calculations.
• There are many examples of other registers (Flags, Control Registers,
etc.)
• The GPR can be thought as an array of elements indexed by
numbers of registers encoded in instructions.
• In general, the maximum number of the GRP is equal to 2 𝑁, where N
is the maximal number of bits that can be encoded in a instruction as
a register number.

Operations
Common types:
• Set a register to constant value or value of other register (move operation).
• Loads (memory → register ) & stores (register ← memory)
• Read and write data from hardware devices (I/O) – not used in our project
• Arithmetic and Logic:
• +, -, *, /, =. . .
• And, Or, Xor, Not
• Compare two values of registers
• Control flow (taking decision: loops, if-else)
• branch to another location (set new value into PC)
• conditionally branch (if (condition) then PC new value)
• save current location and jump to new location (Procedure call)
