Oracle SQL Tutorial 30 - UTF-8 and UTF-16 Character Sets
 
04:01
A few videos ago we discussed UTF-8 and UTF-16 encoding, but when we are working with a database we do not worry about encodings as much as we do character sets. That's because a specific character set is going to have a specific encoding. The reason I am making this video is to introduce you to the most common character sets and to teach you the differences. That’s because as we go into the national character sets we need to understand the information taught in this video. So the first character set I am going to teach you about is AL32UTF8. AL32UTF8 is a character set that uses the uff-8 encoding and each character can take up to 4 bytes with the utf-8 encoding. There is another character set (not encoding) called utf8 (no hyphen) which is also encoded with UTF-8. This can be a little confusing because UTF8 is the name of an encoding and a character set, but bear with me. Both of these character sets are UTF-8 encoded, but UTF8 uses an older version of UTF-8 encoding. Generally, they work about the same, but the way certain characters are stored is slightly different, specifically way certain characters are stored is slightly different, specifically what are known as supplementary characters, which take up 4 bytes. The max size for a UTF8 character set is 3 bytes, as they do not directly support the supplementary characters as 4 bytes but instead store them across 2 groups of 3 bytes each. Oracle recommends that you use AL32UTF8 for all future development instead of the archaic UTF8 character set. There is another character set that you should know about, and that is AL16UTF16, which uses the UTF-16 encoding. Watch my video over UTF-8 and UTF-16 to learn more about UTF-16. Lastly, there is a character set known as UTFE, which uses an encoding known as UTF-EBCDIC. This is like a super archaic character set, and I'm not even going to talk about it. I thought I would at least mention it as it is going to come up a bit in the next video's topic. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Oracle SQL Tutorial 27 - CHAR Part 1
 
03:52
This video and the next is going to cover CHAR and NCHAR. Be sure to check out the previous two videos as these are going to introduce you to some foundational knowledge required to understand these data types. CHAR is a fixed-length data type. What that means is that every value for a CHAR column is going to be the same length. You specify the length in parenthesis when you create the table. The thing you need to know though is that the default measurement is in bytes. That means if you specify the length to be CHAR(50), the length of each value will be 50 bytes, by default. If you want to change that to 50 characters, you can pass in the word CHAR as in CHAR(50 CHAR). This is known as a qualifier. Specifically, they are known as length semantics qualifiers (describes the meaning of the given length). Now, I said the default was bytes, but you can actually change the default to characters. In that situation, you can actually use the keyword BYTE to break away from the default. In general, it's best to put CHAR or BYTE even if it is the default. In general, it's best to keep things consistent. It's okay to have these measured in CHAR or BYTE, but it is recommended that every column is the same. It allows you to be more consistent as if some columns measure length in bytes and some measure length in characters, things can get confusing. If you do want to change the default, look up NLS_LENGTH_SEMANTICS as well as the potential problems it may bring. What values are allowed in parenthesis? That is what we are going to discuss in the next video. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Oracle SQL Tutorial 11 - CREATE TABLE
 
05:04
The way you create a table is to use the CREATE TABLE command. CREATE TABLE users() So in this situation, the name comes right after the TABLE keyword. The next thing we do is put all of the columns on a line that we want to put in our table. CREATE TABLE users( user_id, username, first_name, last_name ) Notice the naming conventions here. For this series we are going to make columns with what is known as snake casing. This is where each individual word is separated by an underscore. if you have more than one column, all of them have to have commas except the last one. The comma is a way to say that another column is coming, so you don't need to do it on the last one. Now you would think we were done, but we also have to say what data type each column is. Later we will extensively discuss data types so we can focus on them exclusively. For now, here are the data types we are going to use: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50), first_name VARCHAR2(50), last_name VARCHAR2(50) ) Now, inside of the parenthesis for varchar2, we pass in a number... This is the max length of the string. But the question is, what is it measured in? The default is actually in bytes, not characters. For example if we have the string hello, it is 5 characters, but it might take up a total of 10 bytes of storage. So I would recommend adding the keyword char right after the number so it defaults to 50 characters, not bytes. CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR), first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) This will work to create a table, but it's really missing a lot of information… which column is the primary key? Are we adding any indexes? Is there any thing else we need to say about these columns? So as you can tell, we are making progress, but there is still so much to learn. The biggest gotcha to remember from this video is that the data type VARCHAR ends in a 2, stupid, right? who would end the name of something with a 2? Once again, this is Caleb from CalebTheVideoMaker2, and we will catch you in the next one! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ HELP 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!)

How Many Different Values Can be Stored in Bit Data Type - SQL Server Tutorial
 
07:59
Bit is integer data type that can store 0,1 or Null. Bit take One byte ( 8 Bits) in memory to store these values for us. We often use this data type for the columns where we want to show if the record is active or In- Active. You can call those type of columns as status columns/ Flag Columns etc. As we know that bit can store only three possible values but when it comes to inserting that values it is Bit confusing. If you will insert 'TRUE' , It will take that as 1. If you will insert 'False', SQL Server will translate that to 0. There are more confusing part to it;) Watch the video and you will see what I am talking about BIT Data type in SQL Server.

When You Can't Apply Oracle Security Patches
 
01:00:52
Are you not applying, or maybe having difficulty in applying, Oracle security patches in a timely manner? Are you quarters or years behind on security patches? Due to lack of security patch support by Oracle for software versions older than eighteen months, or business constraints limiting patching, security patches often are not applied in a timely manner. This presentation discusses the common challenges in applying the security patches, strategies to overcome these challenges, and mitigating controls that might be used to protect against these security vulnerabilities in the Oracle Database and Oracle E-Business Suite.

Oracle SQL Tutorial 26 - UTF-8 and UTF-16
 
05:46
UTF-8 and UTF-16 are different encodings for the Unicode character set. Let's discuss UTF-8 first. UTF-8 is what is known as a variable-length character set. This means that the amount of storage a character takes up depends on what character it is. For example, if we store the character A, it will only take up one byte. In fact, ASCII is a subset of UTF-8. That means UTF-8 encoding can work with ASCII data. If you are new to computer storage, a byte is a very small amount of information. The smallest thing a computer can store is a bit. 1 or 0. On or off. There are 8 bits in a byte, 1024 bytes in a kilobyte, 1024 kilobytes in a megabyte, 1024 megabytes in a gigabyte, and 1024 gigabytes in a terabyte, and 1024 terabytes in a petabyte. Considering it is completely possible for a database to be multiple petabytes, you can understand that a byte is very small. If you store a non-English character, the size of UTF-8 will increase to 2, 3, or 4 bytes. If you think back to when we used the VARCHAR data type, we passed in 50 CHAR. The reason we throw in that CHAR is that the default for Oracle is 50 characters. Now you can understand why adding the CHAR might be important. If a character can take up multiple bytes, you cannot guarantee 50 characters. Now, on to UTF-16. UTF-16 is also a variable length encoding, but it differs in that It is either 2 or 4 bytes. That means to store an A, it now takes two bytes rather than one. Even though a byte is so small, when you are storing billions of characters, an unnecessary byte really adds up to a lot of wasted storage. We can only represent so many characters with 2 bytes. When we run out of options, we move to four bytes to allow for other characters. Which do we use? It often depends on what platform you are on and also what languages you are working with. For example, if you are working with Asian language, UTF-16 stores each character in 2 bytes while UTF-8 stores each character in 3 bytes. So you could save space by using UTF-16. Additionally, UTF-16 works better when you are writing code in Java or something from Microsoft .NET because UTF-16, or a subset of it called UCS-2, is widely adopted. Other than that, UTF-8 will be the one you want. Now that we have built a pretty good foundation of character sets, we can now continue our discussion of data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

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!)

CppCon 2018: Bob Steagall “Fast Conversion From UTF-8 with C++, DFAs, and SSE Intrinsics”
 
01:09:40
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — UTF-8 is taking on an increasingly important role in text processing. Many applications require the conversion of UTF-8 to UTF-16 or UTF-32, but typical conversion algorithms are sub-optimal. This talk will describe a fast, correct, DFA-based approach to UTF-8 conversion that requires only three simple lookup tables and a small amount of straightforward C++ code. We'll begin with a quick review UTF-8 and its relation to UTF-16 and UTF-32, as well as the concept of code units and code points. Next, we'll look at the layout of bits within a UTF-8 byte sequence, and from that, show a simple algorithm for converting from UTF-8 to UTF-32. Along the way will be a definition of overlong and invalid byte sequences. Following that will be a discussion of how to construct a DFA to perform the same operations as the simple algorithm. We'll then look at code for the DFA traversal underlying the basic conversion algorithm, and how to gain an additional performance boost by using SSE intrinsics. Finally, we'll compare the performance of this approach to several commonly-available implementations on Windows and Linux, and show how it's possible to do significantly faster conversions. — Bob Steagall, KEWB Computing CppCon Poster Chair I've been working in C++ since discovering the second edition of The C++ Programming Language in a college bookstore in 1992.

Oracle SQL Tutorial 31 - NCHAR Part 2
 
03:12
This video is going to be part 2 of NCHAR. That's because I have a bit more things to say about it before we move on to other data types. The first thing I wanted to mention is that if you declare an NCHAR(50), it is going to always be 50 characters. You do not need to use the CHAR or BYTE keyword in parenthesis to specify which you would like. We've said that NCHAR uses Unicode, but as we've learned in the last video, there are many character sets that use Unicode. Which character set is NCHAR going to use? That decision is based off of what your database's national character set is. So for every database you can declare a database character set and you can declare a national character set. The national character set is what is used for this data type. There are two options for the national character set, AL16UTF16, and UTF8. The default is AL16UTF16, which uses the utf-16 encoding. The Oracle docs has a lot of pros and cons for each one, but in general the defaults are default for a reason, so AL16UTF16 usually works fine. Now, a few videos ago I made a comment about the CHAR and NCHAR data types and how they might not be recommended. Why so? The reason is that CHAR is secretly just a VARCHAR2 that is padded to take up a full length. It does not save space nor improve performance in the database, so the chances are you are never going to want to use it. That being said, everything you've learned has not been a waste because a lot can be applied to the VARCHAR2 and NVARCHAR2 data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Data Types in Java
 
03:00
Checkout my Full course on JAVA : https://www.udemy.com/java-for-complete-beginers-programming-fundamentals/?couponCode=YTFOR10 Primitive types are the most basic data types available within the Java language. There are 8: boolean, byte, char, short, int, long, float and double. These types serve as the building blocks of data manipulation in Java. Such types serve only one purpose — containing pure, simple values of a kind. Because these data types are defined into the Java type system by default, they come with a number of operations predefined. You can not define a new operation for such primitive types. In the Java type system, there are three further categories of primitives: Numeric primitives: short, int, long, float and double. These primitive data types hold only numeric data. Operations associated with such data types are those of simple arithmetic (addition, subtraction, etc.) or of comparisons (is greater than, is equal to, etc.) Textual primitives: byte and char. These primitive data types hold characters (that can be Unicode alphabets or even numbers). Operations associated with such types are those of textual manipulation (comparing two words, joining characters to make words, etc.). However, byte and char can also support arithmetic operations. Boolean and null primitives: boolean and null. All the primitive types have a fixed size. Thus, the primitive types are limited to a range of values. A smaller primitive type (byte) can contain less values than a bigger one (long).

Socket Programming in Java One Way
 
12:01
Define IP address and port number for client and server connection. Server socket is used for multiple client connection with server. Every client requires one socket. We have to create two classes one for client and one for server.

Videos Available for Download - http://www.udemy.com/calebthevideomaker2-database-and-mysql-classes/ Playlist - http://www.youtube.com/watch?v=krx-w9icrkU&list=PL405B31DD586979DE Welcome to your very first video in this series, MySQL Datatypes! Please subscribe and like my videos, it means a TON to me. Thanks :) This is simply a small course to introduce you to all of the datatypes(excluding spatial, which I will not be covering in this course). All of the datatypes are broken into 4 sections, these are Numeric, Date and Time, String, and Spatial. In all, these are the datatypes I will be covering: tinyint, smallint, mediumint, int, bigint, decimal, float, double, real, bit, boolean, serial, date, datetime, timestamp, time, year, char, varchar, tinytext, text, mediumtext, longtext, binary, varbinary, tinyblob, mediumblob, blob, longblob, enum, and set. Wooah that's a lot. haha. I will not be going over geometry, point, linestring, polygon, multipoint, or multilinestring. If you want to learn more about Spatial types, start here: http://dev.mysql.com/doc/refman/5.6/en/mysql-spatial-datatypes.html Want more information about what is covered in these videos? Always be sure to read the supporting page in the MySQL manual. http://dev.mysql.com/doc/refman/5.6/en/index.html Video information: Char and Varchar ___________________________ Char has a character range from 0 up to 255, varchar allows up to 65535. a max length can be specified in parenthesis such as char(40). char is right padded to fit the specified amount of characters, and the spaces are then removed on retrieval. Only trailing spaces will be removed. for example. Cat_hat__ will come out as cat_hat. This can be a bad thing if you need to store spaces. you will need to use varchar instead. If a value entered is too long, it will be "truncated," or cut to length. Extra info ________ a character set is an allowed range of characters that are entered into an entry. such as UTF-8. Utf 8 is 3 bytes for every character. the storing information for varchar and char are like this.. char - string length. varchar - string length+1. A 10 character entry using UTF-8 would then take 30 bytes in char, and 31 bytes in varchar, but if only 5 characters are entered, it will be 30 bytes for char, and 16 for varchar. This is because char stores the trailing spaces till the requested size is full (in this case 10). A table maximum row size is 65535, so this means if you have a varchar 65535 that is completely full in one column, that is the max allowed stored across that column. Any corrections needing made in these videos please message me. Thank you!

Smart Coding: Ep. 11 - Memory.
 
06:29
In this episode, we investigate computer memory and use this to learn more about Java's data types. Reddit ► https://www.reddit.com/r/CoderTheTyler Twitter ► https://twitter.com/coderthetyler Facebook ► https://www.facebook.com/coderthetyler/ Google+ ► https://plus.google.com/u/0/104036828711619051405 GitHub ► https://github.com/CoderTheTyler If you were interested, adding 1 to a byte in Java doesn't actually yield -128. This is because, although Java explicity declares byte as a data type, any mathematical operation done on it will first convert it to an int. But if you take 128 and turn it into a byte, it will yield -128. Data types really aren't one of Java's strong points. Here are some helpful resources to expand your understanding of data types and computer memory: Oracle Java Doc "Primitive Data Types" https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html Java In A Nutshell "Primitive Data Types" http://docstore.mik.ua/orelly/java-ent/jnut/ch02_04.htm Math Is Fun "Binary Number System" https://www.mathsisfun.com/binary-number-system.html Math Is Fun "Binary to Decimal to Hexidecimal Converter" https://www.mathsisfun.com/binary-decimal-hexadecimal-converter.html Unicode Consortium "What is Unicode?" http://unicode.org/standard/WhatIsUnicode.html Java For Complete Beginners "Boolean Values" http://www.homeandlearn.co.uk/java/boolean_values.html The following include a more advanced discussion of computer memory and how Java's memory model works: TutorialsPoint "Computer - Memory" http://www.tutorialspoint.com/computer_fundamentals/computer_memory.htm Oracel "Understanding Memory Management" https://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/geninfo/diagnos/garbage_collect.html Oh yes.

Black Hat USA 2010: HTTPS Can Byte Me 2/4
 
14:58
Speakers: Robert Hansen, Josh Sokol HTTPS was created to protect confidentiality and prove integrity of content passed over the web. It has essentially become the de-facto standard for internet commerce transport security. Over the years a number of exploits have attacked the principle, underlying PKI infrastructure and overall design of HTTPS. This presentation will drive another nail in the HTTPS coffin through a number of new exploitation techniques leveraging man-in-the-middle attacks; the goal of which is to break confidentiality and integrity of HTTPS traffic. The impact of these flaws suggests a need for changes in the ways we protect the transmission of data online. For more information click here (http://bit.ly/dwlBpJ)
