MySQL 26 - VARCHAR Data Type
 
04:29
Varchar is very similar to CHAR in that it is used to store strings, but there are some pretty big differences. The first difference is that when you store data less than the max it does not pad it with spaces to make it fit. The benefit in this is that you will save storage. The downside to this is that now MySQL is going to have to keep track of how many characters you have. To do this, each value is going to have an additional byte or two that MySQL can use. The max length is 65535 bytes. That is per value in that column! But you have to keep in mind encodings. If your characters are encoded with something such as UTF-8, each character can take up multiple bytes. The max size for a character in this case is 3 bytes. That means that we really can't store that many characters. Additionally, MySQL has a row limit of 65535 bytes (potential bytes…meaning declared sizes). What does this mean? It means that if you make this too big, you are not going to be able to create other columns. Earlier I said that there will be an additional byte or two for each value you put into this column. The purpose of this is to keep track of how long the string is. Why one or two and not one? The reason being is because with one byte we can only count to 255. if we want to keep track of bytes after that we need two bytes. This means that we actually can't store quite 65535 bytes. Realistically, we can't store that much because we have to store the length of the string, and each character can take up to 3 bytes which can push us over the row limit. This means the real max is a little less than a third of that. Not every character is going to take up 3 bytes, but MySQL assumes it will as to not cut you short. This is slightly different than CHAR because char you can store up to 255 characters, not bytes. Even if you use an encoding where some characters take up multiple bytes, you can still store 255 of them. Remember that reason for this is that VARCHAR is subject to the row-limit. MySQL will not let you go past the max and will tell you the appropriate max, so don't worry about it too much. You should try not to push your limits. Plus, most of the time you will not come even close to the max for most columns. Should you use the max? Varchar will only store what is needed to store a value, but you should still try to have the max size no more than what is needed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Every VARCHAR2(N) Declaration a Bug in PL/SQL!?
 
07:51
Every VARCHAR2(N) Declaration a Bug!? That's right. VARCHAR2 declarations mean that you have to provide an "N" or constraint on the size of the variable. If you have such declarations all over your code, that's a form of hard-coding and you are likely to get hammered by VALUE_ERROR exceptions. This video shows how to fix this problem. See the Practically Perfect PL/SQL YouTube channel for related videos. https://www.youtube.com/channel/UCpJpLMRm452kVcie3RpINPw ============================================ Copyright © 2015 Oracle and/or its affiliates.

Check out my Blog: http://exceltraining101.blogspot.com This video shows how to convert comma separated row records into multiple rows. There are two examples: (1) A simple solution using paste special transpose and (2) using Power Query to unpivot the comma separated values. The second example would be used in situations where the records could be in the thousands or even millions of records. P.S.

DEF CON 21 - Ming Chow - Abusing NoSQL Databases
 
20:27
Abusing NoSQL Databases Ming Chow Lecturer, Tufts University Department of Computer Science The days of selecting from a few SQL database options for an application are over. There is now a plethora of NoSQL database options to choose from: some are better than others for certain jobs. There are good reasons why developers are choosing them over traditional SQL databases including performance, scalabiltiy, and ease-of-use. Unfortunately like for many hot techologies, security is largely an afterthought in NoSQL databases. This short but concise presentation will illustrate how poor the quality of security in many NoSQL database systems is. This presentation will not be confined to one particular NoSQL database system. Two sets of security issues will be discussed: those that affect all NoSQL database systems such as defaults, authentication, encryption; and those that affect specific NoSQL database systems such as MongoDB and CouchDB. The ideas that we now have a complicated heterogeneous problem and that defense-in-depth is even more necessary will be stressed. There is a common misconception that SQL injection attacks are eliminated by using a NoSQL database system. While specifically SQL injection is largely eliminated, injection attack vectors have increased thanks to JavaScript and the flexibility of NoSQL databases. This presentation will present and demo new classes of injection attacks. Attendees should be familiar with JavaScript and JSON. Ming Chow (@tufts_cs_mchow) is a Lecturer at the Tufts University Department of Computer Science. His areas of work are in web and mobile engineering and web security. He teaches courses largely in the undergraduate curriculum including the second course in the major sequence, Web Programming, Music Apps on the iPad, and Introduction to Computer Security. He was also a web application developer for ten years at Harvard University. Ming has spoken at numerous organizations and conferences including the High Technology Crime Investigation Association - New England Chapter (HTCIA-NE), the Massachusetts Office of the Attorney General (AGO), John Hancock, OWASP, InfoSec World (2011 and 2012), DEF CON 19 (2011), the Design Automation Conference (2011), Intel, and the SOURCE Conference (Boston 2013). Ming's projects in information security include building numerous CTF challenges, Internet investigations, HTML5 and JavaScript security, and Android forensics.

Refactoring a 1000 Lines of Code Method into Clean(er) Code (in Serbian)
 
01:06:13
Long functions in even longer classes can often be found in mature code bases. Even though every programmer knows it's wrong to keep such a beast in production, every one of us has been feeding one of those for at least some time. In this lecture, we will show the process of building large functions from scratch. We will then turn attention to one such function, which has about 1000 lines of code. You will see why we need to break such monstrous functions into smaller chunks and then we will embark on a voyage to refactor and redesign it into smaller chunks of code. If you have passion for Sudoku, then the example we present will surely amuse you. The program we will be dealing with is setting up Sudoku problems and then it solves each problem, verbalizing all decisions and explaining the solution in common English sentences. But, the way in which this interesting program does its task is, at the same time, the greatest impediment to its further development. That is the point at which this lecture begins. Before watching this recording, you may wish to try fixing the same code on your own. Please download the initial solution from GitHub repository: https://github.com/zoran-horvat/sudoku-kata

RailsConf 2017: Developer Happiness on the Front End with Elm by Kevin Yank Ruby and Rails famously prioritised developer happiness, and took the world by storm. Elm, a new language that compiles to JavaScript, proves that putting developer happiness first can produce very different results on the front end! Born out of Haskell, Elm is as unlike Ruby as programming languages get, but in this session we’ll see how its particular blend of design decisions tackles everything that’s painful about front-end development, making it an excellent choice for the curious Rubyist’s next favorite language.

Universally unique identifier
 
20:39
A universally unique identifier (UUID) is an identifier standard used in software construction, standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE). The intent of UUIDs is to enable distributed systems to uniquely identify information without significant central coordination. In this context the word unique should be taken to mean "practically unique" rather than "guaranteed unique". Since the identifiers have a finite size, it is possible for two differing items to share the same identifier. The identifier size and generation process need to be selected so as to make this sufficiently improbable in practice. Anyone can create a UUID and use it to identify something with reasonable confidence that the same identifier will never be unintentionally created by anyone to identify something else. Information labeled with UUIDs can therefore be later combined into a single database without needing to resolve identifier (ID) conflicts. This video is targeted to blind users.

It is particularly useful in handling structured data where there are relations between different entities/variables of the data. SQL offers two main advantages over older read/write APIs like ISAM or VSAM: first, it introduced the concept of accessing many records with one single command; and second, it eliminates the need to specify how to reach a record, e.g. with or without an index. Originally based upon relational algebra and tuple relational calculus, SQL consists of many types of statements, which may be informally classed as sublanguages, commonly: a data query language (DQL), a data definition language (DDL), a data control language (DCL), and a data manipulation language (DML). The scope of SQL includes data query, data manipulation (insert, update and delete), data definition (schema creation and modification), and data access control. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements. SQL was one of the first commercial languages for Edgar F. Codd's relational model, as described in his influential 1970 paper, "A Relational Model of Data for Large Shared Data Banks". Despite not entirely adhering to the relational model as described by Codd, it became the most widely used database language.SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987. Since then, the standard has been revised to include a larger set of features. Despite the existence of such standards, most SQL code is not completely portable among different database systems without adjustments.

Despite not entirely adhering to the relational model as described by Codd, it became the most widely used database language.SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987. Since then, the standard has been revised to include a larger set of features. Despite the existence of such standards, most SQL code is not completely portable among different database systems without adjustments.

RubyConf 2016 - Ruby’s C Extension Problem and How We're Solving It by Chris Seaton
 
35:28
RubyConf 2016 - Ruby’s C Extension Problem and How We're Solving It by Chris Seaton Ruby’s C extensions have so far been the best way to improve the performance of Ruby code. Ironically, they are now holding performance back, because they expose the internals of Ruby and mean we aren’t free to make major changes to how Ruby works. In JRuby+Truffle we have a radical solution to this problem – we’re going to interpret the source code of your C extensions, like how Ruby interprets Ruby code. Combined with a JIT this lets us optimise Ruby but keep support for C extensions.

NIPS 2011 Big Learning - Algorithms, Systems, & Tools Workshop: Hazy - Making Data-driven...
 
54:59
Big Learning Workshop: Algorithms, Systems, and Tools for Learning at Scale at NIPS 2011 Invited Talk: Hazy: Making Data-driven Statistical Applications Easier to build and Maintain by Chris Re Christopher (Chris) Ré is currently an assistant professor in the department of Computer Sciences at the University of Wisconsin-Madison. The goal of his work is to enable users and developers to build applications that more deeply understand data. In many applications, machines can only understand the meaning of data statistically, e.g., user-generated text or data from sensors. Abstract: The main question driving my group's research is: how does one deploy statistical data-analysis tools to enhance data driven systems? Our goal is to find abstractions that one needs to deploy and maintain such systems. In this talk, I describe my group's attack on this question by building a diverse set of statistical-based data-driven applications: a system whose goal is to read the Web and answer complex questions, a muon detector in collaboration with a neutrino telescope called IceCube, and a social-science applications involving rich content (OCR and speech data). Even in this diverse set, my group has found common abstractions that we are exploiting to build and to maintain systems. Of particular relevance to this workshop is that I have heard of applications in each of these domains referred to as "big data." Nevertheless, in our experience in each of these tasks, after appropriate preprocessing, the relevant data can be stored in a few terabytes -- small enough to fit entirely in RAM or on a handful of disks. As a result, it is unclear to me that scale is the most pressing concern for academics. I argue that dealing with data at TB scale is still challenging, useful, and fun, and I will describe some of our work in this direction. This is joint work with Benjamin Recht, Stephen J. Wright, and the Hazy Team
