Working with the Trace File Analyzer Collector
 
28:22
The Trace File Analyzer (TFA) Collector Tool is a utility for collecting first failure diagnostics when creating Service Requests with Oracle Support. Using TFA Collector to make diagnostic collections removes questions about what files to collect and upload. TFA knows about all the well known Oracle and operating system diagnostic locations and collects only files that have been modified proximate to problem time specified from any of those well known locations. Larger files are also pruned proximate to problem time specified to reduce the size of the upload. If the system is a clustered environment TFA collects relevant diagnostics from the remote nodes as well. All of this can be accomplished with one simple command. Key features of TFA Collector include: RAC and single instance non-RAC support Time-based collection of relevant files OS Clusterware ASM DB OSW and CHMOS etc Large file pruning Cluster-wide time-relevant collections Analytics for key files DB alert logs Clusterware alert logs ASM alert logs system messages OSWatcher top and slabinfo data Flexible command-line interface Copyright © 2014 Oracle and/or its affiliates.

Oracle SQL Tutorial 14 - Column-Level and Table-Level Constraints
 
04:15
In the previous video we talked about adding constraints at the column-level. We made it nice and simple by only requiring a few keywords, but the problem we were having is that we could not assign a name to the constraint, which many people like to do so we can reference easily if we need to at a later time. To do this, it requires a little bit more typing, but it will give us extra flexibility and many consider it to be the higher quality approach to adding constraints. Let's go though a simple example. Let's say we have a users table with a user_id column that we want to make a primary key. We will create the table like this: CREATE TABLE( user_ id NUMBER PRIMARY KEY ) Instead of adding the PRIMARY KEY keywords after the data type, we add: CONSTRAINT user_pk PRIMARY KEY Now, we have assigned the name user_pk to this constraint. You can do the same with other constraints, such as UNIQUE. The syntax would be CONSTRAINT username_un UNIQUE. The other way to create constraints requires to put all of our constraints at the bottom of our table creation rather than inline with the column. This type of constraint is known as a table-level constraints. To make a column a primary key using table-level constraints, we add it to the CREATE TABLE command as if it is another row and use the CONSTRAINT keyword to tell Oracle that what is coming is a constraint, not a column in our table. CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR), CONSTRAINT username_un UNIQUE (username), CONSTRAINT users_pk PRIMARY KEY (user_id) ) The primary differences here is that you have to put the column you are talking about in parenthesis after the PRIMARY KEY keyword. That's because it's at the end of the table and you need a way to tell it what column you are talking about. The option of putting it at the end of the table has the added benefit in this situation because if we needed to have a primary key that is the combination of multiple columns, we can do that by just adding the other column in the PRIMARY KEY parenthesis right after a comma. In summary, there are three ways to make constraints. The first is at the column level, unnamed. The second is at the column level, named. The third is at the table level, also named. In the next video we are going to create a named constraint in Oracle SQL Developer, so stay tuned and be sure to subscribe! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Post-Quantum Zero-Knowledge and Signatures from Symmetric-Key
 
33:34
We propose a new class of post-quantum digital signature schemes that: (a) derive their security entirely from the security of symmetric-key primitives, believed to be quantum-secure, and (b) have extremely small keypairs, and, (c) are highly parametrizable. In our signature constructions, the public key is an image y=f(x) of a one-way function f and secret key x. A signature is a non-interactive zero-knowledge proof of x, that incorporates a message to be signed. For this proof, we leverage recent progress of Giacomelli et al. (USENIX'16) in constructing an efficient sigma protocol for statements over general circuits. We improve this sigma protocol to reduce proof sizes by a factor of two, at no additional computational cost. While this is of independent interest as it yields more compact proofs for any circuit, it also decreases our signature sizes. We consider two possibilities for making the proof non-interactive, the Fiat-Shamir transform, and Unruh's transform (EUROCRYPT'12,'15,'16). The former has smaller signatures, while the latter has a security analysis in the quantum-accessible random oracle model. By customizing Unruh's transform to our application, the overhead is reduced to 1.6x when compared to the Fiat-Shamir transform, which does not have a rigorous post-quantum security analysis. We implement and benchmark both approaches and explore the possible choice of f, taking advantage of the recent trend to strive for practical symmetric ciphers with a particularly low number of multiplications and end up using LowMC. This is joint work with Melissa Chase, David Derler, Steven Goldfeder, Claudio Orlandi, Christian Rechberger, Daniel Slamanig and Greg Zaverucha.  See more on this video at https://www.microsoft.com/en-us/research/video/post-quantum-zero-knowledge-and-signatures-from-symmetric-key/

Don Johnson, Oracle - Oracle OpenWorld - #oow16 - #theCUBE
 
14:05
Why Infrustructure-as-a-Service is critical to innovation | #OOW by Teryn O'Brien | Sep 21, 2016 Infrastructure as a Service (IaaS) offers organizations multiple benefits in the cloud, including dynamic scaling, a lower total cost of ownership and flexibility, among many other benefits. So, as more businesses search for IaaS solutions, Oracle has rounded out its product offerings in this area to include bare metal cloud servers and enhancements to its Oracle Cloud services. Don Johnson, VP of Engineering at Oracle, spoke with John Furrier (@furrier) and Peter Burris (@plburris), cohosts of theCUBE, from the SiliconANGLE Media team, during Oracle OpenWorld 2016 to talk about the importance of IaaS. The importance of IaaS for innovation There’s basically two strata of cloud, according to Johnson. The cloud platform and everything up above (apps, etc). “IaaS is a fundamental and foundational building block — and all of the characteristics that everything up above relies on or requires is basically enabled by infrastructure,” he said. A company either has infrastructure or they don’t. For Oracle, there is no option but to invest in the cloud, according to Johnson. Innovation requires it for success in the future market. “We’re a cloud platform company; this is a foundational piece,” he emphasized. “We’re pursuing this very progressively.” The importance of IaaS for enterprises “If you have … a large existing infrastructure and deployment — typically on premise — you have a lot of constraints,” explained Johnson. “And it’s difficult to actually move into this new environment and take advantage of all that it has to offer.” Oracle has identified a number of areas that it wanted to do better in its Cloud services: security, reliability, governance, performance, the ability to harness modern technologies and, most importantly, flexibility. “A core thing that we did … is the virtual network,” Johnson said. “And we made a fundamental choice that the way in which we’re gonna do the virtual network is to pull the virtualization into the network itself where we think it belongs.” RELATED: Art meets Big Data: How DreamWorks is utilizing analytics in modern animation | #SeizeTheData This means that Oracle is able to plug anything into a virtualized network for enterprises, giving customer bare metal compute. “That was key design criteria,” Johnson added. The design is much more friendly to any large enterprise or business that is “outside of the sweet spot of what an infrastructure like, let’s say, Amazon was originally designed for.”

Pat Dorsey: "The Little Book that Builds Wealth" | Talks at Google
 
01:10:15
What does it mean for a company to have a moat? What are the key drivers to valuation? Pat Dorsey will use examples to shed light on these, and more questions. About the Book: Capitalism works. That’s why most businesses with high returns on capital attract competition that forces down profitability over time. However, a small minority of companies are able to defy the laws of economic gravity by creating competitive advantages, or “economic moats” that insulate them from competition and allow them to maintain high returns on capital. After spending fifteen years analyzing thousands of companies, Pat has identified a handful of structural characteristics that create competitive advantage. He will discuss these characteristics, how management teams can create and destroy competitive advantage, and how he applies competitive analysis in managing institutional capital at Dorsey Asset Management. About the author: Pat is the founder of Dorsey Asset Management, which manages concentrated global portfolios for institutional investors. Prior to starting Dorsey Asset, Pat was Director of Research for Sanibel Captiva Trust, an independent trust company with approximately $1 billion in assets under management serving high net worth clients.

Quantum Computing for Computer Scientists
 
01:28:23
This talk discards hand-wavy pop-science metaphors and answers a simple question: from a computer science perspective, how can a quantum computer outperform a classical computer? Attendees will learn the following: - Representing computation with basic linear algebra (matrices and vectors) - The computational workings of qbits, superposition, and quantum logic gates - Solving the Deutsch oracle problem: the simplest problem where a quantum computer outperforms classical methods - Bonus topics: quantum entanglement and teleportation The talk concludes with a live demonstration of quantum entanglement on a real-world quantum computer, and a demo of the Deutsch oracle problem implemented in Q# with the Microsoft Quantum Development Kit. This talk assumes no prerequisite knowledge, although comfort with basic linear algebra (matrices, vectors, matrix multiplication) will ease understanding.

04 How to configure Hash partition in Oracle
 
06:56
Hash partitioning Use hash partitioning if your data does not easily lend itself to range partitioning, but you would like to partition for performance and manageability reasons. Hash partitioning provides a method of evenly distributing data across a specified number of partitions. Rows are mapped into partitions based on a hash value of the partitioning key The following example shows how to create a hash partition table. The following example creates a hash-partitioned table. The partitioning column is partno, four partitions are created and assigned system generated names, and they are placed in four named tablespaces (tab1,tab2, ...). CREATE TABLE products (partno NUMBER, description VARCHAR2 (60)) PARTITION BY HASH (partno) PARTITIONS 4 STORE IN (tab1, tab2, tab3, tab4);

What is a zero-knowledge proof?
 
06:28
One of the more elegant and counterintuitive ideas in modern cryptography is the notion of a zero-knowledge proof (ZNP). A ZNP allows one party (the prover) to prove to another (the verifier) that they know a secret without revealing any information about the secret itself.It’s a totally wild idea that has deep implications for online security.

Leftover Hash Lemma, Revisited (Crypto 2011)
 
22:10
Talk at Crypto 2011, August 15, 2011. Boaz Barak, Yevgeniy Dodis, Hugo Krawczyk, Olivier Pereira, Krzysztof Pietrzak, François-Xavier Standaert, and Yu Yu Microsoft Research New England; New York University; IBM Research; Université Catholique de Louvain; CWI Amsterdam; Université Catholique de Louvain;and East China Normal University Abstract. The famous Leftover Hash Lemma (LHL) states that (almost) universal hash functions are good randomness extractors. Despite its numerous applications, LHL-based extractors suffer from the following two drawbacks: Large Entropy Loss: to extract $v$ bits from distribution $X$ of min-entropy $m$ which are $\epsilon$-close to uniform, one must set $v \le m - 2*\log(1/\epsilon)$, meaning that the entropy loss $L = m-v \ge 2*\log(1/\epsilon)$. Large Seed Length: the seed length $n$ of (almost) universal hash function required by the LHL must be at least $n \ge \min(u-v, v + 2*\log(1/\epsilon))-O(1)$, where $u$ is the length of the source. Quite surprisingly, we show that both limitations of the LHL — large entropy loss and large seed — can often be overcome (or, at least, mitigated) in various quite general scenarios. First, we show that entropy loss could be reduced to $L = \log (1/\epsilon)$ for the setting of deriving secret keys for a wide range of cryptographic applications. Specifically, the security of these schemes with an LHL-derived key gracefully degrades from $\epsilon$ to at most $\epsilon+\sqrt{\epsilon 2^{-L}}$. (Notice that, unlike standard LHL, this bound is meaningful even when one extracts more bits than the min-entropy we have!) Based on these results we build a general computational extractor that enjoys low entropy loss and can be used to instantiate a generic key derivation function for any cryptographic application. Second, we study the soundness of the natural expand-then-extract approach, where one uses a pseudorandom generator (PRG) to expand a short "input seed" $S$ into a longer "output seed" $S'$, and then use the resulting $S'$ as the seed required by the LHL (or, more generally, by any randomness extractor). We show that, in general, the expand-then extract approach is not sound if the Decisional Diffie-Hellman assumption is true. Despite that, we show that it is sound either: (1) when extracting a "small" (logarithmic in the security of the PRG) number of bits; or (2) in minicrypt. Implication (2) suggests that the expand-then-extract approach is likely secure when used with "practical" PRGs, despite lacking a reductionist proof of security!

What is CRYPTO CLOUD COMPUTING? What does CRYPTO CLOUD COMPUTING mean? CRYPTO CLOUD COMPUTING meaning - CRYPTO CLOUD COMPUTING definition - CRYPTO CLOUD COMPUTING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Cloud computing is a combination of IaaS, PaaS, SaaS. To construct a secure cloud computing system, security at infrastructure, service platforms and application software levels have to be studied for a secure cloud computing system. Information encryption is one of effective means to achieve cloud computing information security. Traditionally, information encryption focuses on specified stages and operations, such as data encryption. For cloud computing, a system level design has to be implemented. Crypto cloud computing is a new secure cloud computing architecture. It can provide protection of information security at the system level, and allows users access to shared services conveniently and accurately. Crypto cloud computing protects individual’s connections with the outside world. It can protect the personal privacy without any delay of information exchange. Crypto cloud computing is based on the Quantum Direct Key system. Quantum Direct Key (QDK) is a set of advanced asymmetric offline key mechanism. In this mechanism, all entities get public and private key pair according to their ID. Each entity only holds its own private key, but has a public key generator to generate any public key. In this system, an entity can produce the public key of any other entities offline, no any third-party agency (such as CA) is necessary. Crypto cloud computing based on QDK can avoid network traffic congestion, and other drawbacks using current encryption system. In the crypto cloud computing system, each entity encrypts data using his/her own private key. All elements in the system such as cloud computing infrastructure units, platform, virtualization tools and all involved entities have their own keys. While fulfilling their own functions of information exchange and processing, all these elements will use the public key and private key to perform authentication first. What’s more, events occur in the cloud computing are also assigned a unique key. In this way, crypto cloud system guarantees the security and credibility of information exchange. Current cloud computing structure is developed for data and computing sharing. Security is not priority of system. On the contrary, encryption and security are inherently integrated in the crypto cloud computing based on the QDK. QDK authorized function units are bricks of crypto cloud computing. Besides primary function of data en/decryption, crypto cloud computing also provides many security related functions. For example, all channels sign transmit data using with their own keys, and the receiving terminals can avoid hijacking by verifying signature. What’s more, the exact position of security leakage can be identified determined by analyzing digital signatures of forged data. Based on such capabilities, crypto-related functions can be provided as services in cloud, which is named as ‘Crypto as a service (CAAS)’. Crypto cloud computing is not only the advances in information technology, but also innovation of logical relationship. In crypto cloud computing system, non-system data is not allowed to store and transmit. Private Key and offline public key, play a role of identification and certification in the process of information exchange. In this way, the cloud establishes a relationship of trust with a customer. Data identification depends on the logical relationship of mutual trust or need, and the logical relationship depends on the cloud customer. Crypto cloud computing is a new framework for cyber resource sharing. It protects data security and privacy. Well, in cloud environment, crypto cloud computing guarantees the information security and integrity during whole procedure. Security management of cloud computing can also be performed by authorizing the signatures of every element involved. What’s more, a user can retrieve all related resources using his QDK key. There is no personal privacy under the current cloud framework, as pointed out by Mark Zuckerberg, 'the Age of Privacy Is Over '.However, with the development of crypto cloud computing, we can resolve the conflict between services data sharing and privacy security. It opens up new prospects for the development of information sharing technology.

Part IV: How Can Echelon Provide Revenue Assurance?
 
01:10
COS Revenue Assurance App - detect losses in distribution Echelon's Revenue Assurance App simplifies your job of finding losses on the low voltage grid. It tracks energy usage both at distribution transformers and at all meters attached to that transformer. Comparing both sets of precise data, it automatically detects discrepancies and generates alarms when specific thresholds have been exceeded. It's an easier, less manual way to discover loss. Monitor the key parameters of technical and non-technical loss to preserve revenue and gain grid efficiencies: * Local sensors monitor consumption at the transformer * Near real-time comparison of energy delivered by transformer vs. total metered energy from all attached meters yield possible sources of non-technical losses * When analysis is performed on Echelon's Edge Control Nodes, utilities can process information locally and avoid backhauling large amounts of meter data to head-end, savings WAN costs Benefits: * Identify losses in distribution networks * Protect revenue and detect theft * Identify tampering at the meter * Proactively respond to losses * Reduce manual process/time needed to investigate tampering and losses * Identify sources of above-average losses to focus grid improvements for better ROI

RetroGaming On Android - Playing Games & Emulators On Android x86 6.0.1 On A Core i3 PC ✅
 
59:44
Android On A PC seems to be a pretty viable retrogaming & emulation solution offering quite a solid performance just like you get on the Android gaming handhelds - but with more power under the hood. Lakka is a lean and mean Linux Distribution providing a PS3 like GUI (see separate video here: https://www.youtube.com/watch?v=4cS-43kXApM Retropie on Ubuntu is more versatile but less monkey proof, take a look at the video here: https://www.youtube.com/watch?v=G8r-B8x1a30 Computers Core2Duo, i3, i5 or similarly specced AMD CPUs will be capable of near perfect emulation. But access to it through the Desktop GUI of Windows or Linux is less console like and one does need a mouse and keyboard to operate. Same goes for Android to some extend. The overhead of the GUI and all the processes running on this little system do take a toll on its responsiveness when running games and/or emulators on Windows, Ubuntu/Android. It runs great on Lakka but how will it run on Android? It seems that the Android Launcher has very little impact on the machine's performance. Even running a fancy 3d animated Matrix desktop doesn't alter that. A wireless Logitech F710 or a Logitech Rumblepad 2 (predecessor) will be easily configured (Android doesn't even need configuring of the controller, but certain emulators and software does, but that's easily done). Two fairly similar systems running Ubuntu/Lakka and Android 6.0.1 x86 in this set of videos: Dell Optiplex 980 Intel Core i3 550 / 3.2 GHz, Intel Q57 Express chipset 4-Gb DDR3 RAM, 250Gb SSD HD Intel GMA 4500 Dynamic Video Memory Technology 5.0, DVI, displayport, VGA (Lakka & Android 6.0.1 - separate video) Lenovo ThinkCentre Edge E73 SFF (10AU003FMH) Intel Core i3-4130 Intel Haswell, Intel H81 chipset 4-12Gb DDR3 RAM, 1Gb SATA HD Intel HD Graphics 4400, NVidia GT210 PCIe (this video) I own all games shown here on there original media, I don't condone piracy. To me emulation is about preservation and ease of use and saving wear and tear on the original systems. And a fascination about how these systems work and how to make differences in architecture go away through software. I think on these i3 systems both Lakka (solid 60fps, no lag whatsoever, solid console like experience using a PS3 like interfact) and Android (can do a Lakka-like experience if you stick to the RetroArch interface but offers more versatility and choice in emulators) offer a similar experience with Lakka working pretty much out of the box with only needing to drop in system files and game files. Android needs a bit more configuring but is more versatile.
