TrustedDB is a database system that uses trusted hardware to enable private SQL queries on outsourced data. It addresses limitations of existing encrypted database systems by using tamper-proof cryptographic processors like the IBM 4764. TrustedDB optimizes query execution by running sensitive operations inside the secure processor and non-sensitive operations on the untrusted server to improve performance while reducing costs compared to software-only encrypted databases. The system was built and evaluated to demonstrate the advantages of a trusted hardware approach for private database processing.

Managing Multi-Tenant SaaS Applications at ScaleMongoDB
Speaker: Justin LaBreck, Senior Consulting Engineer, Professional Services, MongoDB
Level: 200 (Intermediate)
Track: Application Architecture
Multi-tenant applications face unique challenges at scale. A mix of hardware, software, and developer costs make implementing software-as-a-service (SaaS) and basic application architecture expensive and complex making growth problematic.
In this talk, we will explore the strategies, trade-offs, and “gotchas” common in multi-tenant environments. We draw from daily work with MongoDB customers and application development in the SaaS events industry migrating from one multi-tenant strategy to another. We'll discuss several approaches on the shared-to-isolation spectrum with cost and benefit considerations for each. We’ll even offer tips so today’s application and MongoDB design choices don’t affect tomorrow’s bottom line.
What You Will Learn:
- What strategies exist for storing data from multiple clients?
- How can these strategies be compared for cost effectiveness?
- How can these strategies be compared for cost effectiveness?
How can MongoDB features be leveraged for future scale?

Lightning Talk #9: How UX and Data Storytelling Can Shape Policy by Mika Aldabaux singapore
How can we take UX and Data Storytelling out of the tech context and use them to change the way government behaves?
Showcasing the truth is the highest goal of data storytelling. Because the design of a chart can affect the interpretation of data in a major way, one must wield visual tools with care and deliberation. Using quantitative facts to evoke an emotional response is best achieved with the combination of UX and data storytelling.
Content personalisation is becoming more prevalent. A site, it's content and/or it's products, change dynamically according to the specific needs of the user. SEO needs to ensure we do not fall behind of this trend.
Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
By David F. Larcker, Stephen A. Miles, and Brian Tayan
Stanford Closer Look Series
Overview:
Shareholders pay considerable attention to the choice of executive selected as the new CEO whenever a change in leadership takes place. However, without an inside look at the leading candidates to assume the CEO role, it is difficult for shareholders to tell whether the board has made the correct choice. In this Closer Look, we examine CEO succession events among the largest 100 companies over a ten-year period to determine what happens to the executives who were not selected (i.e., the “succession losers”) and how they perform relative to those who were selected (the “succession winners”).
We ask:
• Are the executives selected for the CEO role really better than those passed over?
• What are the implications for understanding the labor market for executive talent?
• Are differences in performance due to operating conditions or quality of available talent?
• Are boards better at identifying CEO talent than other research generally suggests?

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
Trusted db a trusted hardware based database with privacy and data confidentiality
1. TrustedDB: A Trusted Hardware based Database with
Privacy and Data Confidentiality
ABSTRACT:
Traditionally, as soon as confidentiality becomes a concern, data is encrypted
before outsourcing to a service provider. Any software-based cryptographic
constructs then deployed, for server-side query processing on the encrypted data,
inherently limit query expressiveness. Here, we introduce TrustedDB, an
outsourced database prototype that allows clients to execute SQL queries with
privacy and under regulatory compliance constraints by leveraging server-hosted,
tamper-proof trusted hardware in critical query processing stages, thereby
removing any limitations on the type of supported queries. Despite the cost
overhead and performance limitations of trusted hardware, we show that the costs
per query are orders of magnitude lower than any (existing or) potential future
software-only mechanisms. TrustedDB is built and runs on actual hardware and its
performance and costs are evaluated here.
EXISTING SYSTEM:
Existing research addresses several such security aspects, including access privacy
and searches on encrypted data. In most of these efforts data is encrypted before
2. outsourcing. Once encrypted however, inherent limitations in the types of primitive
operations that can be performed on encrypted data lead to fundamental
expressiveness and practicality constraints. Recent theoretical cryptography results
provide hope by proving the existence of universal homeomorphisms, i.e.,
encryption mechanisms that allow computation of arbitrary functions without
decrypting the inputs. Unfortunately actual instances of such mechanisms seem to
be decades away from being practical
DISADVANTAGES OF EXISTING SYSTEM:
Trusted hardware is generally impractical due to its performance limitations and
higher acquisition costs. As a result, with very few exceptions, these efforts have
stopped short of proposing or building full - fledged database processing engines.
Computation inside secure processors is orders of magnitude cheaper than any
equivalent cryptographic operation performed on the provider’s unsecured server
hardware, despite the overall greater acquisition cost of secure hardware.
PROPOSED SYSTEM:
we posit that a full-fledged, privacy enabling secure database leveraging server-
side trusted hardware can be built and run at a fraction of the cost of any (existing
or future) cryptography-enabled private data processing on common server
3. hardware. We validate this by designing and building TrustedDB, a SQL database
processing engine that makes use of tamperproof cryptographic coprocessors such
as the IBM 4764 in close proximity to the outsourced data. Tamper resistant
designs however are significantly constrained in both computational ability and
memory capacity which makes implementing fully featured database solutions
using secure coprocessors (SCPUs) very challenging. TrustedDB achieves this by
utilizing common unsecured server resources to the maximum extent possible.
E.g., TrustedDB enables the SCPU to transparently access external storage while
preserving data confidentiality with on-the-fly encryption. This eliminates the
limitations on the size of databases that can be supported. Moreover, client queries
are pre-processed to identify sensitive components to be run inside the SCPU.
Non-sensitive operations are off-loaded to the untrusted host server. This greatly
improves performance and reduces the cost of transactions.
ADVANTAGES OF PROPOSED SYSTEM:
(i) The introduction of new cost models and insights that explain and
quantify the advantages of deploying trusted hardware for data
processing,
(ii) the design, development, and evaluation of TrustedDB, a trusted
hardware based relational database with full data confidentiality, and
4. (iii) Detailed query optimization techniques in a trusted hardware-based query
execution model.
