NAME
perlrecharclass - Perl Regular Expression Character ClassesDESCRIPTION
The top level documentation about Perl regular expressions is found in perlre.This manual page discusses the syntax and use of character classes in Perl Regular Expressions.
A character class is a way of denoting a set of characters, in such a way that one character of the set is matched. It's important to remember that matching a character class consumes exactly one character in the source string. (The source string is the string the regular expression is matched against.)
There are three types of character classes in Perl regular expressions: the dot, backslashed sequences, and the bracketed form.
The dot
The dot (or period), "." is probably the most used, and certainly the most well-known character class. By default, a dot matches any character, except for the newline. The default can be changed to add matching the newline with the single line modifier: either for the entire regular expression using the "/s" modifier, or locally using "(?s)".Here are some examples:
"a" =~ /./ # Match "." =~ /./ # Match "" =~ /./ # No match (dot has to match a character) "\n" =~ /./ # No match (dot does not match a newline) "\n" =~ /./s # Match (global 'single line' modifier) "\n" =~ /(?s:.)/ # Match (local 'single line' modifier) "ab" =~ /^.$/ # No match (dot matches one character)
Backslashed sequences
Perl regular expressions contain many backslashed sequences that constitute a character class. That is, they will match a single character, if that character belongs to a specific set of characters (defined by the sequence). A backslashed sequence is a sequence of characters starting with a backslash. Not all backslashed sequences are character class; for a full list, see perlrebackslash.Here's a list of the backslashed sequences, which are discussed in more detail below.
\d Match a digit character. \D Match a non-digit character. \w Match a "word" character.   \H Match a character that isn't horizontal white space. \v Match a vertical white space character. \V Match a character that isn't vertical white space. \pP, \p{Prop} Match a character matching a Unicode property. \PP, \P{Prop} Match a character that doesn't match a Unicode property.
"\d" matches a single character that is considered to be a digit. What is considered a digit depends on the internal encoding of the source string. If the source string is in UTF-8 format, "\d" not only matches the digits '0' - '9', but also Arabic, Devanagari and digits from other languages. Otherwise, if there is a locale in effect, it will match whatever characters the locale considers digits. Without a locale, "\d" matches the digits '0' to '9'. See ``Locale, Unicode and UTF-8''.
Any character that isn't matched by "\d" will be matched by "\D".
"\w" matches a single word character: an alphanumeric character (that is, an alphabetic character, or a digit), or the underscore ("_"). What is considered a word character depends on the internal encoding of the string. If it's in UTF-8 format, "\w" matches those characters that are considered word characters in the Unicode database. That is, it not only matches ASCII letters, but also Thai letters, Greek letters, etc. If the source string isn't in UTF-8 format, "\w" matches those characters that are considered word characters by the current locale. Without a locale in effect, "\w" matches the ASCII letters, digits and the underscore.
Any character that isn't matched by "\w" will be matched by "\W".
"\s" matches any single character that is consider white space. In the ASCII range, "\s" matches the horizontal tab ("\t"), the new line ("\n"), the form feed ("\f"), the carriage return ("\r"), and the space (the vertical tab, "\cK" is not matched by "\s"). The exact set of characters matched by "\s" depends on whether the source string is in UTF-8 format. If it is, "\s" matches what is considered white space in the Unicode database. Otherwise, if there is a locale in effect, "\s" matches whatever is considered white space by the current locale. Without a locale, "\s" matches the five characters mentioned in the beginning of this paragraph. Perhaps the most notable difference is that "\s" matches a non-breaking space only if the non-breaking space is in a UTF-8 encoded string.
Any character that isn't matched by "\s" will be matched by "\S".
"\h" will match any character that is considered horizontal white space; this includes the space and the tab characters. "\H" will match any character that is not considered horizontal white space.
"\v" will match any character that is considered vertical white space; this includes the carriage return and line feed characters (newline). "\V" will match any character that is not considered vertical white space.
"\R" matches anything that can be considered a newline under Unicode rules. It's not a character class, as it can match a multi-character sequence. Therefore, it cannot be used inside a bracketed character class. Details are discussed in perlrebackslash.
"\h", "\H", "\v", "\V", and "\R" are new in perl 5.10.0.
Note that unlike "\s", "\d" and "\w", "\h" and "\v" always match the same characters, regardless whether the source string is in UTF-8 format or not. The set of characters they match is also not influenced by locale.
One might think that "\s" is equivalent with "[\h\v]". This is not true. The vertical tab ("\x0b") is not matched by "\s", it is however considered vertical white space. Furthermore, if the source string is not in UTF-8 format, the next line ("\x85") and the no-break space ("\xA0") are not matched by "\s", but are by "\v" and "\h" respectively. If the source string is in UTF-8 format, both the next line and the no-break space are matched by "\s".
The following table is a complete listing of characters matched by "\s", "\h" and "\v".
The first column gives the code point of the character (in hex format), the second column gives the (Unicode) name.  To match a number (that consists of integers), use "\d+"; to match a word, use "\w+".
"\pP" and "\p{Prop}" are character classes to match characters that fit given Unicode classes. One letter classes can be used in the "\pP" form, with the class name following the "\p", otherwise, the property name is enclosed in braces, and follows the "\p". For instance, a match for a number can be written as "/\pN/" or as "/\p{Number}/". Lowercase letters are matched by the property LowercaseLetter which has as short form Ll. They have to be written as "/\p{Ll}/" or "/\p{LowercaseLetter}/". "/\pLl/" is valid, but means something different. It matches a two character string: a letter (Unicode property "\pL"), followed by a lowercase "l".
For a list of possible properties, see ``Unicode Character Properties'' in perlunicode. It is also possible to defined your own properties. This is discussed in ``User-Defined Character Properties'' in perlunicode.
"a" =~ /\w/ # Match, "a" is a 'word' character. "7" =~ /\w/ # Match, "7" is a 'word' character as well. "a" =~ /\d/ # No match, "a" isn't a digit. "7" =~ /\d/ # Match, "7" is a digit. " " =~ /\s/ # Match, a space is white space. "a" =~ /\D/ # Match, "a" is a non-digit. "7" =~ /\D/ # No match, "7" is not a non-digit. " " =~ /\S/ # No match, a space is not non-white space. " " =~ /\h/ # Match, space is horizontal white space. " " =~ /\v/ # No match, space is not vertical white space. "\r" =~ /\v/ # Match, a return is vertical white space. "a" =~ /\pL/ # Match, "a" is a letter. "a" =~ /\p{Lu}/ # No match, /\p{Lu}/ matches upper case letters. "\x{0e0b}" =~ /\p{Thai}/ # Match, \x{0e0b} is the character # 'THAI CHARACTER SO SO', and that's in # Thai Unicode class. "a" =~ /\P{Lao}/ # Match, as "a" is not a Laoian character.
Bracketed Character Classes
The third form of character class you can use in Perl regular expressions is the bracketed form. In its simplest form, it lists the characters that may be matched inside square brackets, like this: "[aeiou]". This matches one of "a", "e", "i", "o" or "u". Just as the other character classes, exactly one character will be matched. To match a longer string consisting of characters mentioned in the characters class, follow the character class with a quantifier. For instance, "[aeiou]+" matches a string of one or more lowercase ASCII vowels.Repeating a character in a character class has no effect; it's considered to be in the set only once.
Examples:
"e" =~ /[aeiou]/ # Match, as "e" is listed in the class. "p" =~ /[aeiou]/ # No match, "p" is not listed in the class. "ae" =~ /^[aeiou]$/ # No match, a character class only matches # a single character. "ae" =~ /^[aeiou]+$/ # Match, due to the quantifier.
Special Characters Inside a Bracketed Character Class
Most characters that are meta characters in regular expressions (that is, characters that carry a special meaning like "*" or "(") lose their special meaning and can be used inside a character class without the need to escape them. For instance, "[()]" matches either an opening parenthesis, or a closing parenthesis, and the parens inside the character class don't group or capture.
Characters that may carry a special meaning inside a character class are: "\", "^", "-", "[" and "]", and are discussed below. They can be escaped with a backslash, although this is sometimes not needed, in which case the backslash may be omitted.
The sequence "\b" is special inside a bracketed character class. While outside the character class "\b" is an assertion indicating a point that does not have either two word characters or two non-word characters on either side, inside a bracketed character class, "\b" matches a backspace character.
A "[" is not special inside a character class, unless it's the start of a POSIX character class (see below). It normally does not need escaping.
A "]" is either the end of a POSIX character class (see below), or it signals the end of the bracketed character class. Normally it needs escaping if you want to include a "]" in the set of characters. However, if the "]" is the first (or the second if the first character is a caret) character of a bracketed character class, it does not denote the end of the class (as you cannot have an empty class) and is considered part of the set of characters that can be matched without escaping.
Examples:
"+" =~ /[+?*]/ # Match, "+" in a character class is not special. "\cH" =~ /[\b]/ # Match, \b inside in a character class # is equivalent with a backspace. "]" =~ /[][]/ # Match, as the character class contains. # both [ and ]. "[]" =~ /[[]]/ # Match, the pattern contains a character class # containing just ], and the character class is # followed by a ].
It is not uncommon to want to match a range of characters. Luckily, instead of listing all the characters in the range, one may use the hyphen ("-"). If inside a bracketed character class you have two characters separated by a hyphen, it's treated as if all the characters between the two are in the class. For instance, "[0-9]" matches any ASCII digit, and "[a-m]" matches any lowercase letter from the first half of the ASCII alphabet.
Note that the two characters on either side of the hyphen are not necessary both letters or both digits. Any character is possible, although not advisable. "['-?]" contains a range of characters, but most people will not know which characters that will be. Furthermore, such ranges may lead to portability problems if the code has to run on a platform that uses a different character set, such as EBCDIC.
If a hyphen in a character class cannot be part of a range, for instance because it is the first or the last character of the character class, or if it immediately follows a range, the hyphen isn't special, and will be considered a character that may be matched. You have to escape the hyphen with a backslash if you want to have a hyphen in your set of characters to be matched, and its position in the class is such that it can be considered part of a range.
Examples:
[a-z] # Matches a character that is a lower case ASCII letter. [a-fz] # Matches any letter between 'a' and 'f' (inclusive) or the # letter 'z'. [-z] # Matches either a hyphen ('-') or the letter 'z'. [a-f-m] # Matches any letter between 'a' and 'f' (inclusive), the # hyphen ('-'), or the letter 'm'. ['-?] # Matches any of the characters '()*+,-./0123456789:;<=>? # (But not on an EBCDIC platform).
It is also possible to instead list the characters you do not want to match. You can do so by using a caret ("^") as the first character in the character class. For instance, "[^a-z]" matches a character that is not a lowercase ASCII letter.
This syntax make the caret a special character inside a bracketed character class, but only if it is the first character of the class. So if you want to have the caret as one of the characters you want to match, you either have to escape the caret, or not list it first.
Examples:
"e" =~ /[^aeiou]/ # No match, the 'e' is listed. "x" =~ /[^aeiou]/ # Match, as 'x' isn't a lowercase vowel. "^" =~ /[^^]/ # No match, matches anything that isn't a caret. "^" =~ /[x^]/ # Match, caret is not special here.
You can put a backslash sequence character class inside a bracketed character class, and it will act just as if you put all the characters matched by the backslash sequence inside the character class. For instance, "[a-f\d]" will match any digit, or any of the lowercase letters between 'a' and 'f' inclusive.
Examples:
/[\p{Thai}\d]/ # Matches a character that is either a Thai # character, or a digit. /[^\p{Arabic}()]/ # Matches a character that is neither an Arabic # character, nor a parenthesis.
Backslash sequence character classes cannot form one of the endpoints of a range.
Posix character classes have the form "[:class:]", where class is name, and the "[:" and ":]" delimiters. Posix character classes appear inside bracketed character classes, and are a convenient and descriptive way of listing a group of characters. Be careful about the syntax,
# Correct: $string =~ /[[:alpha:]]/ # Incorrect (will warn): $string =~ /[:alpha:]/
The latter pattern would be a character class consisting of a colon, and the letters "a", "l", "p" and "h".
Perl recognizes the following POSIX character classes:
alpha Any alphabetical character. alnum Any alphanumerical character. ascii Any ASCII character. blank A GNU extension, equal to a space or a horizontal tab ("\t"). cntrl Any control character. digit Any digit, equivalent to "\d". graph Any printable character, excluding a space. lower Any lowercase character. print Any printable character, including a space. punct Any punctuation character. space Any white space character. "\s" plus the vertical tab ("\cK"). upper Any uppercase character. word Any "word" character, equivalent to "\w". xdigit Any hexadecimal digit, '0' - '9', 'a' - 'f', 'A' - 'F'.
The exact set of characters matched depends on whether the source string is internally in UTF-8 format or not. See ``Locale, Unicode and UTF-8''.
Most POSIX character classes have "\p" counterparts. The difference is that the "\p" classes will always match according to the Unicode properties, regardless whether the string is in UTF-8 format or not.
The following table shows the relation between POSIX character classes and the Unicode properties:
[[:...:]] \p{...} backslash alpha IsAlpha alnum IsAlnum ascii IsASCII blank cntrl IsCntrl digit IsDigit \d graph IsGraph lower IsLower print IsPrint punct IsPunct space IsSpace IsSpacePerl \s upper IsUpper word IsWord xdigit IsXDigit
Some character classes may have a non-obvious name:
- cntrl
- Any control character. Usually, control characters don't produce output as such, but instead control the terminal somehow: for example newline and backspace are control characters. All characters with "ord()" less than 32 are usually classified as control characters (in ASCII, the ISO Latin character sets, and Unicode), as is the character "ord()" value of 127 ("DEL").
- graph
- Any character that is graphical, that is, visible. This class consists of all the alphanumerical characters and all punctuation characters.
- All printable characters, which is the set of all the graphical characters plus the space.
- punct
- Any punctuation (special) character.
A Perl extension to the POSIX character class is the ability to negate it. This is done by prefixing the class name with a caret ("^"). Some examples:
POSIX Unicode Backslash [[:^digit:]] \P{IsDigit} \D [[:^space:]] \P{IsSpace} \S [[:^word:]] \P{IsWord} \W
Perl will recognize the POSIX character classes "[=class=]", and "[.class.]", but does not (yet?) support this construct. Use of such a construct will lead to an error.
/[[:digit:]]/ # Matches a character that is a digit. /[01[:lower:]]/ # Matches a character that is either a # lowercase letter, or '0' or '1'. /[[:digit:][:^xdigit:]]/ # Matches a character that can be anything, # but the letters 'a' to 'f' in either case. # This is because the character class contains # all digits, and anything that isn't a # hex digit, resulting in a class containing # all characters, but the letters 'a' to 'f' # and 'A' to 'F'.
Locale, Unicode and UTF-8
Some of the character classes have a somewhat different behaviour depending on the internal encoding of the source string, and the locale that is in effect."\w", "\d", "\s" and the POSIX character classes (and their negations, including "\W", "\D", "\S") suffer from this behaviour.
The rule is that if the source string is in UTF-8 format, the character classes match according to the Unicode properties. If the source string isn't, then the character classes match according to whatever locale is in effect. If there is no locale, they match the ASCII defaults (52 letters, 10 digits and underscore for "\w", 0 to 9 for "\d", etc).
This usually means that if you are matching against characters whose "ord()" values are between 128 and 255 inclusive, your character class may match or not depending on the current locale, and whether the source string is in UTF-8 format. The string will be in UTF-8 format if it contains characters whose "ord()" value exceeds 255. But a string may be in UTF-8 format without it having such characters.
For portability reasons, it may be better to not use "\w", "\d", "\s" or the POSIX character classes, and use the Unicode properties instead.
$str = "\xDF"; # $str is not in UTF-8 format. $str =~ /^\w/; # No match, as $str isn't in UTF-8 format. $str .= "\x{0e0b}"; # Now $str is in UTF-8 format. $str =~ /^\w/; # Match! $str is now in UTF-8 format. chop $str; $str =~ /^\w/; # Still a match! $str remains in UTF-8 format.

vue-image-alpha
vue-image-alpha is a Vue component allowing to use light-weight transparent images on a
website.
It is a remastered version of imgAlpha.js I ceated a few years ago. This Vue version has a more efficient
code and a faster image processing running in the background using Web Workers and buffer images.
How it Works
vue-image-alpha uses 2 compressed images such as jpeg format to build a light-weight transparent image. No more ugly GIF and no more heavy PNG!!
Simply save your image in 2 regular jpeg files:
- The color image (on a plain color background)
- The alpha image (black is transparent and white is opaque)
Installation
vue-image-alpha is a Vue component that can be installed as dependency in you Vue CLI project.
The easiest way to install it is using NPM:
npm install --save vue-image-alpha
Usage
Component Initialization
All you need to do is to import vue-alpha-image in your Vue code
import ImgAlpha from 'vue-image-alpha'
...
export default {
name: 'MyApp',
components: {
ImgAlpha,
...
},
...
},
Component Use
Use the component in your html or template code
<img-alpha src="/path/to/myImage.jpg" src-alpha="/path/to/myImage-alpha.jpg" bg-color="#FFFFFF"></img-alpha>
or with data binding
<img-alpha :src="require('/path/to/myImage.jpg')" :src-alpha="require('/path/to/myImage-alpha.jpg')" bg-color="#FFFFFF"></img-alpha>

src
The src defines the color image source.
src-alpha
The src-alpha defines the alpha image used to make the color image transparent.
If the alpha image is not provided, the image transparency processing will be skipped and the image will be displayed as a regular image.
bg-color (optional)
The bg-color defines the background color of the color image.
By default, the bg-color is white (#FFFFFF)
This prop is used to provide a better alpha blending accuracy if you use a background color in the color image different than white.

My SQL Bad Habits
I’m reasonably proficient at SQL – a coworker when pseudocoding some logic for him pointed out that my pseudocode is what he thought was executable SQL. I’m fully capable of writing clear and readable SQL – which most SQL is not. Despite that I still have several bad habits when it comes to SQL. Without further adieu heres some of my dirty laundry so hopefully others can not make the same mistakes.
Order/Group by Column Numbers
When quickly iterating on a query its a lot less typing to put the column number as the thing you want to order by. Here’s a quick lightweight example:
SELECT
email,
created_at
FROM
users
ORDER BY 2 DESC
LIMIT 5;
This gives me my last 5 users that have signed up for my site. Of course as soon as I have this I may want to add some data to it, like their first name so I can send them a welcome email. I quickly alter the query to:
SELECT
email,
first_name,
created_at
FROM
users
ORDER BY 2 DESC
LIMIT 5;
And now I have 5 users that have signed up ordered by their first name. Sure its obvious when you have 1 column you’re ordering by, but when you have GROUP BY 1, 2, 3, 4, 5, 6
which is actually open in one of my tabs currently its a bit more confusing….
Though if you really want to have some fun, share a query with someone that looks something like this:
SELECT
email as "3",
first_name "2",
created_at "1"
FROM
users
ORDER BY "1", "3" DESC
LIMIT 5;
Implicit Joins
I seldom use the syntax INNER JOIN
. Instead I simply put the two tables in my where clause and ensure I have a where condition. The problem with ensuring I have a where condition is sometimes I don’t, especially when you’re dealing with 3 tables.
SELECT
email,
product.name,
product.price
FROM
users,
orders,
items
WHERE users.id = orders.user_id
AND orders.id = items.order_id
Is less clear (especially when dealing with 5-6 tables) than the alternative:
SELECT
email,
product.name,
product.price
FROM users
INNER JOIN orders on users.id = orders.user_id
INNER JOIN items on orders.id = items.order_id
Lack of comments
I comment my SQL far less than I comment my code, yet it can be done just as easily. For example I have this in one of my queries:
SELECT convert_from(CAST(E'\\x' || array_to_string(ARRAY(
SELECT
CASE
WHEN length(r.m[1]) = 1
THEN encode(convert_to(r.m[1], 'SQL_ASCII'), 'hex')
ELSE substring(r.m[1] from 2 for 2)
END
FROM regexp_matches(url_here, '%[0-9a-f][0-9a-f]|.', 'gi') AS r(m)
), '') AS bytea), 'UTF8');
While this has its own issues theres no documentation around what this actually does, in contrast:
--- DECODES url ---
SELECT convert_from(CAST(E'\\x' || array_to_string(ARRAY(
SELECT
CASE
WHEN length(r.m[1]) = 1
THEN encode(convert_to(r.m[1], 'SQL_ASCII'), 'hex')
ELSE substring(r.m[1] from 2 for 2)
END
FROM regexp_matches(url_here, '%[0-9a-f][0-9a-f]|.', 'gi') AS r(m)
), '') AS bytea), 'UTF8');
Comments also work well inline at the end of a line.
Large Manually Generated Lists
A lot of times in working with some specific data set I’ll manually or automatically generate a list that I want to filter. A common example is filtering out staging/dev environments. I’ll often manually search and prune the list, then save that result for the queries I’m going to build going forward. This is a bit of effort but still feels reasonable the downside is it results in something like:
SELECT
foo
FROM
bar
WHERE
bar.id NOT IN (34723, 42735, 32321, 47205, 20375, 30261, 26194, 109371, 9313, 6351, 20184, 50273, 34735, 39854, 23954, 25323, 23405, 30528, 50182, 29340, 47659, ... and the list goes on)
SQL is meant to be reasonable for containing some level of logic. Data changes, hard coding keys is going to bite you at some point, spend the extra effort and re-use something thats clear.
What else
I’m sure theres plenty more; I suspect within a few minutes of sitting down with someone they could point out some other bad habits. While I know mine at least some of mine I still often know the trade-off. What are yours? I’d love to hear to document them for others so hopefully they can prevent developing the same bad habits. Let me know; craig.kerstiens@gmail.com

A home is a dwelling-place used as a permanent or semi-permanent residence for an individual, family, household or several families in a tribe. It is often a house, apartment, or other building, or alternatively a mobile home, houseboat, yurt or any other portable shelter. Larger groups may live in a nursing home, children's home, convent or any similar institution. A homestead also includes agricultural land and facilities for domesticated animals. Where more secure dwellings are not available, people may live in the informal and sometimes illegal shacks found in slums and shanty towns. More generally, "home" may be considered to be a geographic area, such as a town, village, suburb, city, or country
News is the communication of selected[1] information on current events. It is shared in various ways: among individuals and small groups (such as by word of mouth or newsletters); with wider audiences (such as by publishing, either in print or online, or broadcasting, such as on television or radio); or in ways that blend those traits (such as when social media sharing starts among individuals but goes viral).

Once upon a time, Fadnavis vowed to jail Ajit Pawar
by PTIPolitics does make for strange bedfellows.
Take the case of Devendra Fadnavis, who in 2014 had vowed to send Ajit Pawar to jail for his alleged corruption in the "irrigation scam".
On Saturday, after Fadnavis was sworn in Maharashtra chief minister for a second term, propped up by the man he had termed corrupt not so long ago, videos of his tirade against the NCP leader went viral on social media.
In the video, Fadnavis can be heard describing what Ajit Pawar would be doing in prison after the election.
He would be, said Fadnavis, "Chakki peesing and peesing and peesing", words from the iconic film 'Sholay', used to describe prisoners doing hard, manual labour.
Prime Minister Narendra Modi, who had described the Sharad Pawar-led Nationalist Congress Party as "Naturally Corrupt Party", was also among those who congratulated Ajit Pawar after he became the deputy CM.
In a stunning turn of events in Maharashtra, BJP's Fadnavis on Saturday returned as chief minister propped up by Ajit Pawar, who was made his deputy, just hours after the new alliance of Shiv Sena, the NCP and the Congress reached a consensus that Sena chief Uddhav Thackeray will be their chief ministerial candidate.
The Shiv Sena approached the Supreme Court against the "arbitrary and malafide actions/decisions" of Maharashtra governor Bhagat Singh Koshyari of swearing in Fadnavis.
Fadnavis and Ajit Pawar were sworn in by Koshyari at 8 am at a hush hush ceremony here after dramatic midnight developments, leading to the lifting of the President's rule in Maharashtra.

Internet Explorer 4.0 offers customization of the desktop interface through the
Active Desktop. When it is installed on a Compaq Presario with Home Base,
there is an initial conflict.
To remove this conflict, Compaq has provided a program that disables the
Home Base shell.  If you don't run the Prepare Your Computer program before you install
Internet Explorer 4.0, your computer may not function properly.
If you're using one of the computers listed
and run the Prepare Your Computer program, the program makes
these changes to your computer:
- Home Base is removed from your computer. Pressing the
SmartQ button no longer opens Home Base, and Home Base
doesn't start up when you start your computer.
- You can't switch among multiple users through Home
Base. However, you can switch among users by using the Windows
login feature. To change users, click on Start, then on
Log off.... Windows closes all open programs and prompts
you to log in.
- You can't open the Help Center through Home Base. To open
the Help Center, click on Start, then on Run,
then enter the following line in the Run dialog box:
c:\compaq\help\cpqhelp.exe
Important: If you don't want Home Base removed from your computer, you should wait for the next
release of Microsoft Internet Explorer provided by Compaq. This version, which will be available soon, will
correct the conflict with Home Base, and you'll be able to install Internet Explorer
and keep Home Base on your computer.

One day, perhaps a day far off, I would like to move to New Zealand and start my own town. I would call it Blough and I would be the Mayor of Blough.
Blough would be a special place because all eight correct pronunciations of its name would be correct. It’s main trades would be poker, jazz music, wind farms and confused tourists. My favourite pronunciation would be “Blup”.
* Bluff
* Blue
* Blau (to rhyme with “cow”)
* Blow
* Blaw (to rhyme with “saw”)
* Bloff
* Blup
* Bluh (more of a schwa sound)
Welcome to English!

Target file: /dest/home/me/foo/bar
Target file: /dest/home/you/bar/baz
-
Example cmd: cd /home; rsync -a --relative me/foo you/ /dest
+/- pattern: /me/foo/bar (starts at specified path)
+/- pattern: /you/bar/baz (ditto)
Target file: /dest/me/foo/bar
Target file: /dest/you/bar/baz
The easiest way to see what name you should filter is to just look at the output when using --verbose and put a / in front of the name (use the --dry-run option if you're not yet ready to copy any files).
PER-DIRECTORY RULES AND DELETE
Without a delete option, per-directory rules are only relevant on the sending side, so you can feel free to exclude the merge files themselves without affecting the transfer. To make this easy, the oqecq modifier adds this exclude for you, as seen in these two equivalent commands:
-
rsync -av --filter=': .excl' --exclude=.excl host:src/dir /dest
rsync -av --filter=':e .excl' host:src/dir /dest
However, if you want to do a delete on the receiving side AND you want some files to be excluded from being deleted, you'll need to be sure that the receiving side knows what files to exclude. The easiest way is to include the per-directory merge files in the transfer and use --delete-after, because this ensures that the receiving side gets all the same exclude rules as the sending side before it tries to delete anything:
- rsync -avF --delete-after host:src/dir /dest
However, if the merge files are not a part of the transfer, you'll need to either specify some global exclude rules (i.e. specified on the command line), or you'll need to maintain your own per-directory merge files on the receiving side. An example of the first is this (assume that the remote .rules files exclude themselves):
rsync -av --filter=': .rules' --filter='. /my/extra.rules' --delete host:src/dir /dest
In the above example the extra.rules file can affect both sides of the transfer, but (on the sending side) the rules are subservient to the rules merged from the .rules files because they were specified after the per-directory merge rule.
In one final example, the remote side is excluding the .rsync-filter files from the transfer, but we want to use our own .rsync-filter files to control what gets deleted on the receiving side. To do this we must specifically exclude the per-directory merge files (so that they don't get deleted) and then put rules into the local files to control what else should not get deleted. Like one of these commands:
rsync -av --filter=':e /.rsync-filter' --delete \ host:src/dir /dest rsync -avFF --delete host:src/dir /dest
BATCH MODE
Batch mode can be used to apply the same set of updates to many identical systems. Suppose one has a tree which is replicated on a number of hosts. Now suppose some changes have been made to this source tree and those changes need to be propagated to the other hosts. In order to do this using batch mode, rsync is run with the write-batch option to apply the changes made to the source tree to one of the destination trees. The write-batch option causes the rsync client to store in a lqbatch filerq all the information needed to repeat this operation against other, identical destination trees.
Generating the batch file once saves having to perform the file status, checksum, and data block generation more than once when updating multiple destination trees. Multicast transport protocols can be used to transfer the batch update files in parallel to many hosts at once, instead of sending the same data to every host individually.
To apply the recorded changes to another destination tree, run rsync with the read-batch option, specifying the name of the same batch file, and the destination tree. Rsync updates the destination tree using the information stored in the batch file.
For your convenience, a script file is also created when the write-batch option is used: it will be named the same as the batch file with lq.shrq appended. This script file contains a command-line suitable for updating a destination tree using the associated batch file. It can be executed using a Bourne (or Bourne-like) shell, optionally passing in an alternate destination tree pathname which is then used instead of the original destination path. This is useful when the destination tree path on the current host differs from the one used to create the batch file.
Examples:
-
$ rsync --write-batch=foo -a host:/source/dir/ /adest/dir/
$ scp foo* remote:
$ ssh remote ./foo.sh /bdest/dir/
-
$ rsync --write-batch=foo -a /source/dir/ /adest/dir/
$ ssh remote rsync --read-batch=- -a /bdest/dir/ <foo
In these examples, rsync is used to update /adest/dir/ from /source/dir/ and the information to repeat this operation is stored in lqfoorq and lqfoo.shrq. The host lqremoterq is then updated with the batched data going into the directory /bdest/dir. The differences between the two examples reveals some of the flexibility you have in how you deal with batches:
- o
- The first example shows that the initial copy doesn't have to be local --- you can push or pull data to/from a remote host using either the remote-shell syntax or rsync daemon syntax, as desired.
- o
- The first example uses the created lqfoo.shrq file to get the right rsync options when running the read-batch command on the remote host.
- o
-
The second example reads the batch data via standard input so that
the batch file doesn't need to be copied to the remote machine first.
This example avoids the foo.sh script because it needed to use a modified
--read-batch option, but you could edit the script file if you wished to
make use of it (just be sure that no other option is trying to use
standard input, such as the lq--exclude-from=-rq option).
Caveats:
The read-batch option expects the destination tree that it is updating to be identical to the destination tree that was used to create the batch update fileset. When a difference between the destination trees is encountered the update might be discarded with a warning (if the file appears to be up-to-date already) or the file-update may be attempted and then, if the file fails to verify, the update discarded with an error. This means that it should be safe to re-run a read-batch operation if the command got interrupted. If you wish to force the batched-update to always be attempted regardless of the file's size and date, use the -I option (when reading the batch). If an error occurs, the destination tree will probably be in a partially updated state. In that case, rsync can be used in its regular (non-batch) mode of operation to fix up the destination tree.
The rsync version used on all destinations must be at least as new as the one used to generate the batch file. Rsync will die with an error if the protocol version in the batch file is too new for the batch-reading rsync to handle. See also the --protocol option for a way to have the creating rsync generate a batch file that an older rsync can understand. (Note that batch files changed format in version 2.6.3, so mixing versions older than that with newer versions will not work.)
When reading a batch file, rsync will force the value of certain options to match the data in the batch file if you didn't set them to the same as the batch-writing command. Other options can (and should) be changed. For instance --write-batch changes to --read-batch, --files-from is dropped, and the --filter/--include/--exclude options are not needed unless one of the --delete options is specified.
The code that creates the BATCH.sh file transforms any filter/include/exclude options into a single list that is appended as a lqhererq document to the shell script file. An advanced user can use this to modify the exclude list if a change in what gets deleted by --delete is desired. A normal user can ignore this detail and just use the shell script as an easy way to run the appropriate --read-batch command for the batched data.
The original batch mode in rsync was based on lqrsync+rq, but the latest version uses a new implementation.
SYMBOLIC LINKS
Three basic behaviors are possible when rsync encounters a symbolic link in the source directory.
By default, symbolic links are not transferred at all. A message lqskipping non-regularrq file is emitted for any symlinks that exist.
If --links is specified, then symlinks are recreated with the same target on the destination. Note that --archive implies --links.
If --copy-links is specified, then symlinks are lqcollapsedrq by copying their referent, rather than the symlink.
rsync also distinguishes lqsaferq and lqunsaferq symbolic links. An example where this might be used is a web site mirror that wishes ensure the rsync module they copy does not include symbolic links to /etc/passwd in the public section of the site. Using --copy-unsafe-links will cause any links to be copied as the file they point to on the destination. Using --safe-links will cause unsafe links to be omitted altogether. (Note that you must specify --links for --safe-links to have any effect.)
Symbolic links are considered unsafe if they are absolute symlinks (start with /), empty, or if they contain enough lq..rq components to ascend from the directory being copied.
Here's a summary of how the symlink options are interpreted. The list is in order of precedence, so if your combination of options isn't mentioned, use the first line that is a complete subset of your options:
- --copy-links
- Turn all symlinks into normal files (leaving no symlinks for any other options to affect).
- --links --copy-unsafe-links
- Turn all unsafe symlinks into files and duplicate all safe symlinks.
- --copy-unsafe-links
- Turn all unsafe symlinks into files, noisily skip all safe symlinks.
- --links --safe-links
- Duplicate safe symlinks and skip unsafe ones.
- --links
- Duplicate all symlinks.
DIAGNOSTICS
rsync occasionally produces error messages that may seem a little cryptic. The one that seems to cause the most confusion is lqprotocol version mismatch --- is your shell clean?rq.
This message is usually caused by your startup scripts or remote shell facility producing unwanted garbage on the stream that rsync is using for its transport. The way to diagnose this problem is to run your remote shell like this:
- ssh remotehost /bin/true > out.dat
then look at out.dat. If everything is working correctly then out.dat should be a zero length file. If you are getting the above error from rsync then you will probably find that out.dat contains some text or data. Look at the contents and try to work out what is producing it. The most common cause is incorrectly configured shell startup scripts (such as .cshrc or .profile) that contain output statements for non-interactive logins.
If you are having trouble debugging filter patterns, then try specifying the -vv option. At this level of verbosity rsync will show why each individual file is included or excluded.

ENVIRONMENT VARIABLES
- CVSIGNORE
- The CVSIGNORE environment variable supplements any ignore patterns in .cvsignore files. See the --cvs-exclude option for more details.
- RSYNC_ICONV
- Specify a default --iconv setting using this environment variable.
- RSYNC_RSH
- The RSYNC_RSH environment variable allows you to override the default shell used as the transport for rsync. Command line options are permitted after the command name, just as in the -e option.
- RSYNC_PROXY
- The RSYNC_PROXY environment variable allows you to redirect your rsync client to use a web proxy when connecting to a rsync daemon. You should set RSYNC_PROXY to a hostname:port pair.
- RSYNC_PASSWORD
- Setting RSYNC_PASSWORD to the required password allows you to run authenticated rsync connections to an rsync daemon without user intervention. Note that this does not supply a password to a remote shell transport such as ssh; to learn how to do that, consult the remote shell's documentation.
- USER or LOGNAME
- The USER or LOGNAME environment variables are used to determine the default username sent to an rsync daemon. If neither is set, the username defaults to lqnobodyrq.
- HOME
-
The HOME environment variable is used to find the user's
default .cvsignore file.

VERSION
This man page is current for version 3.0.6 of rsync.
INTERNAL OPTIONS
The options --server and --sender are used internally by rsync, and should never be typed by a user under normal circumstances. Some awareness of these options may be needed in certain scenarios, such as when setting up a login that can only run an rsync command. For instance, the support directory of the rsync distribution has an example script named rrsync (for restricted rsync) that can be used with a restricted ssh login.

This software extracts building locations from USGS DRG (Digital Raster Graph) files. It may also work with similar files produced by other organizations, such as scanned international topo quads. The input file is expected to be a TIF, and the output is a VTST (Structures File).
The Image Processing Library (IPL) must be installed for you to compile or run this program. This can be obtained from the VTP CD. Unfortunately it is no longer available directly from its creator.
You may also need to copy the IPL DLLs from the directory in which they were installed (usually C:/Program Files/Intel/plsuite/bin) to a directory on your path (for example, C:/winnt)
If you are going to process a full-size DRG, be aware that you should have at least 128 MB of RAM on your machine - more is better.
Once an image is loaded, user can do the following:
- Zoom in/out (using menu or +/- keys)
- SuperZoom: Can zoom in by factor of 3X by hitting the spacebar. Hitting the spacebar a second time causes you to return to your original position. This is very useful for precisely labeling the centers of buildings after you've done the automatic processing.
- Scroll around the image using the scrollbars or the up/down/left/right arrow keys on the keyboard
- View the image at it's original resolution (from the View menu, select "View Full Resolution Image")
- In Building Select mode:
- Left mouse button click will place or remove a building mark
- Left mouse button drag will form a rectangle until released; when released, all building marks inside the rectangle will be removed.
- Middle mouse button drag enables scrolling around the image
- In Hand mode:
- Left mouse button drag enables scrolling around the image
- This mode is not needed unless you do not have a middle mouse button
Extract Buildings -- This function is the meat of the application, and is composed of the following parts:
- PreFloodFill
This is highly recommended, especially for large files.
- The purpose of the pre-floodfill is to remove objects larger than buildings (such as letters) from the image before the convolve occurs.
- It reduces the amount of false positives in the final output (therefore reducing the amount of user processing required after the convolve).
- Tweaks
: in the file B_ExtractorDoc.cpp, in the PreFloodFillDIB method, the critical line is:
"if (result > #)".
- # represents the number of black pixels the floodfill must encounter (starting from a specific point) in order to remove that object from the image. Buildings in the Hawaii DRG's are approximately 40 pixels in volume, but ones close together can be connected, or buildings can be connected to thin black lines of pixels, which artificially increase the pixel count for the building (which is why it is set at 120 in the code).
- The user can make this number lower:
- + this reduces the number of false positives in the final output
- - this means taking the risk of removing buildings from the image before they can be recognized in the convolve (potentially increases false negatives)
- or higher:
- + higher value means more sure that all buildings will survive to the convolve step
- - increases the number of false positives (since more words will make it to the convolve and be recognized)
- Kernel Size
(PreConvolve)
- Can choose 9x9, 7x7, or 5x5
- 7 x 7 appears to give the best results in tests done to date
- 5 x 5 is not recommended, it was only used in an aborted attempt to incorporate erosion of the image into the processing. The Erode is no longer done, so the 5 x 5 kernel does not return any good results.
- Threshold
(PostConvolve)
- Perhaps the most important decision, the threshold determines where the cut-off is for a building (placing or not placing a building mark at a point in the image).
- Tweaks
:
- If you are getting too many false positives, try a higher threshold. This will reduce them, but will also reduce the number of buildings identified correctly (will increase false negatives)
- If you are getting too many false negatives, try a lower threshold. This will increase the number of buildings labelled correctly, but will cause a corresponding increase in the number of words/marks/etc incorrectly marked as being a building.
- The threshold can be manually set by changing the number passed in to the iplThreshold function. This function is called in B_ExtractorView.cpp, in the OnFunctionsConvolve method
Clear Selected Buildings -- This function clears all building marks from the image. Useful if the user wants to try a different kernel size or threshold setting on an image.
TestIPL -- This function is of no use for building recognition. It was used to test certain aspects of the Intel Image Processing Library during development.
In order to use the VTST files you have generated, copy them to the VTP Enviro data directory Enviro/Data/BuildingData. The next time you run Enviro, they will appear on the "Structures Filename" drop-down control of the Terrain Parameters dialog.

Hi @Reid Barton, I am getting lots of strange errors that claim to be about typeclass inference for has_colimits
. A typical example is:
failed to synthesize type class instance for C : Type u, 𝒞 : category C, _inst_1 : has_colimits C, F G H : PresheafedSpace C, α : F ⟶ G, β : G ⟶ H, x : ↥(F.X) ⊢ Π {J : Type v} {𝒥 : small_category J} (F : J ⥤ C), has_colimit F
(The goal is just the definition of has_colimits C
.)
Do you have any idea what going on here?
The current place it is cropping up, very mysteriously is here, and for now blocking me working on stalks.
Is it some strange bug in Lean dealing with [class]
attributes on function types?
Or maybe I'm doing something dumb.
Yeah I've seen errors like this before. It seems that the @[class] def has_colimits :=
a Pi-type doesn't actually totally work, even though it seems to mostly work. It takes some slightly complicated setup for it to stop working and I never got to the bottom of it.
I think we just need to change each of the classes to be a structure
with instances that specialize has_colimits
-> has_colimits_of_shape
-> has_colimit
and you won't be able to go back the other way from Pi J, has_colimits_of_shape J
to has_colimits
automatically, but that probably doesn't really matter in practice
ok. I will try this out at some point.

This algorithm classifies the trends into linear, quadratic, cubic, concealed and no-trend types. The "concealed trends" are those trends that possess quadratic or cubic forms, but the net change from the start of the time period to the end of the time period hasn't been significant. The "no-trend" category includes simple linear trends with statistically in-significant slope coefficient.

Modeling Stuff Using Ruby Classes.
Crap.
This blog is super late. Again.
This week (uh, I mean last week) we were asked to pick something we'd like to model and show how to do it with Ruby classes, methods and instance variables.
While my first impulse, "Shame Meter!" would surely be hilarious, how about something more positive and productive? A time management tool.
Ideally, I'd like to input tasks that have to get done during the week, and a time estimate of how long each task will take. I want my time manager to break up big tasks and distribute them in chunks of time across the days of the week. Then it could tell me what I should be working on each day, and as I do stuff, track by task how much of the allotted day's time I've used, and warn me if I'm getting off track.
I've been reading Practical Object-Oriented Design in Ruby (aka POODR) by Sandi Metz. I really like it, and I'm going to try and follow some of her recommendations for object oriented design. To the best of my still-fairly-meager ability.
First and foremost? Make sure each class has a single responsibility.
So I have to think specifically about what parts a time manager will need, and then how to translate and organize those parts into classes that are as focused as possible.
I'll probably need classes like "Week", "Timer", "Notifier", "Day", and maybe things like a "DayScheduler" that would break the weekly task time estimates across days. In truth, I'm overwhelmed by the whole animal, so I'm going to start small. I'm pretty sure I'll need a class like this:
Knows the following stuff about itself:
- The task name.
- The amount of time this task has been allotted for the day.
- How much time is left for completion.
(This could maybe be a negative value if I've gone over time.)
- If it's an active task.
(i.e. is it being worked on right now or ignored?)
Can do the following stuff:
- Report its task name
- Report the time allotted for the task for the day
- Report how much time is left for the task
- Report its active status
- Change its active status
- If active, decrement the time allotment with a timer.
(I feel like this timer should be a separate object?)
Oh code that is and does the things above, I shall call you "DayTask". You shall be a class. I hope you shall not suck.
Objects have "noun-y" parts, like properties or states, and "verb-y" parts — which are behaviors, or "actions they can do". The object-creating blueprint that shall be the class "DayTask" will store the things from the "Knows about itself" list in instance variables. The "Can do" stuff will take the form of methods.
After a bit of Googling, it seems like timers can be a bit tricky. In order to keep moving forward, I think it would be best if "DayTask" isn't responsible for timing. I don't know how to implement it yet, and besides, that would violate single responsibility too, right? Maybe "DayTask" just needs to record a time stamp when its active state changes. If there's a time history, it can compare that with the current time (which is easy to get in Ruby) and report back a status based on the active state. Some external object could then be responsible for occasionally asking, "Hey instance of DayTask, how much time remains for your task?" If the task has been inactive, it would respond with "Same as the last time you asked (sheesh)." If it's been active, it can calculate how much time has passed since it got activated, decrement that from the time remaining and report back.
That means I'm going to need one more instance variable: One that can hold the last known time the instance was set to active. And since it's easy, I'll update that variable when the instance gets set to inactive too, because I can already think of 3 possibilities that might need that info. Hopefully that doesn't count too much as "trying to guess the future", which according to POODR is a bad idea.)
So here's what this "DayTask" class might look like:
Click here for the full size code screenshot.
I can already see both my methods are probably violating the "Do only one thing" rule of thumb. The "active" method is esentially flipping a switch to turn time tracking on or off, but it's also recording the time a switch flip happens. The "time_remaining" method is doing that secondary task of time stamping as well. Right now that's probably not a big deal, but since the only-one-thing rule applies to methods too, it's probably not the best design.
That time stamping action could be broken out into its own method. Then the "active" and "time_remaining" methods could call the time stamp method, and it would make it easier to change the stamping system later, if need be. Perhaps from a single value to an array or hash containing a history of time-stamped state changes — which would be necessary if I wanted, someday, to implement some kind of "FillOutMyTimeSheet" functionality.
I'd make that change, but look! I'm out of time.

VOLARE
A Team Driven By Passion.
F1 in Schools is the only global multi-disciplinary challenge in which teams of students aged 9 to 19 deploy CAD/CAM software to collaborate, design, analyse, manufacture, test, and then race miniature compressed air powered balsa wood F1 cars.
How this car became a reality?
We first examined many designs and looked at factors affecting a car's design.
Considering all the physical values, we designed the basis of our car on paper.
With the basis of our design in mind, we set out to create the fastest car around.
When the design was ready in Fusion 360, the model was tested in Virtual Wind Tunnels to check the physical values and make further tweaks.

libs6dns
s6-dns
Software
skarnet.org
The following functions and structures are declared in the s6-dns/s6dns-domain.h header, and implemented in the libs6dns.a or libs6dns.so library.
s6dns_domain provides primitives to perform basic operations on domain names.
A s6dns_domain_t is a structure that s6dns uses internally to represent a domain name. It can be in string form (or decoded form), which is close to the printable form seen by users, or in packet form (or encoded form), which is the format used in the DNS protocol.
A s6dns_domain_t is a flat structure and can be declared on the stack.
int s6dns_domain_fromstring (s6dns_domain_t *d, char const *s, size_t len)
Makes a (string form) domain from string s of length len,
and stores it into *d. Returns 1 if it succeeds, otherwise it
returns 0 and sets errno appropriately - most likely ENAMETOOLONG, i.e.
the name in s is not a well-formed domain name.
unsigned int s6dns_domain_tostring (char *s, unsigned int max, s6dns_domain_t const *d)
Writes into string s the domain contained in *d (in string
form). Returns the number of bytes written, or 0 in case of failure. If
the output would be more than max bytes, 0 ENAMETOOLONG is returned.
int s6dns_domain_noqualify (s6dns_domain_t *d)
Makes sure that *d is fully qualified. This is done without using
qualification: a trailing dot is simply appended if the domain
doesn't already have one. Returns 1 if it succeeds, or 0 if it fails.
unsigned int s6dns_domain_qualify (s6dns_domain_t *list, s6dns_domain_t const *d, char const *rules, unsigned int rulesnum)
Performs qualification on domain *d according to the first
rulesnum rules stored in string rules. Stores the output
(at most rulesnum domains) into the array pointed to by list.
Returns 0 on failure, or the number of written domains if it succeeds. This
number can be lesser than rulesnum, for instance if *d is
already fully qualified.
Valid rules and rulesnum can be obtained via functions
declared in s6dns-rci.h.
int s6dns_domain_encode (s6dns_domain_t *d)
Encodes domain *d from string form to packet form. Returns 1
if it succeeds or 0 if it fails - for instance, *d is not a
valid string form (EINVAL).
unsigned int s6dns_domain_encodelist (s6dns_domain_t *list, unsigned int n)
Encodes n domains pointed to by list from string form to packet form,
stopping at the first failure.
Returns the number of successfully encoded domains, normally n.
int s6dns_domain_decode (s6dns_domain_t *d)
Decodes domain *d from packet form to string form. Returns 1
if it succeeds or 0 if it fails - for instance, *d is not a
valid packet form (EPROTO).
int s6dns_domain_fromstring_noqualify_encode (s6dns_domain_t *d, char const *s, size_t len)
Higher-level function wrapping some of the above. Makes an encoded, fully qualified
(without resorting to qualification) domain from string s of
length len. Returns 1 if it succeeds and 0 if it fails.
unsigned int s6dns_domain_fromstring_qualify_encode (s6dns_domain_t *list, char const *s, size_t len, char const *rules, unsigned int rulesnum)
Another wrapping function. It makes a list of encoded, fully qualified domains,
from string s of length len using rulesnum qualification
rules in rules. It writes at most rulesnum domains into the array
pointed to by list and returns the number of written domains, or 0 on an
error.
void s6dns_domain_arpafromip4 (s6dns_domain_t *d, char const *ip)
Writes into d the in-addr.arpa. domain corresponding to IPv4 address
ip (4 bytes, in network byte order), in string form.
void s6dns_domain_arpafromip6 (s6dns_domain_t *d, char const *ip, unsigned int mask)
Writes into d the ip6.arpa. domain corresponding to the first
mask bits of IPv6 address ip (16 bytes, in network byte order),
in string form.
Only multiples of 4 count for mask, i.e. the output will be the same
if mask is (for instance) 125, 126, 127 or 128.


It was the late fall or early winter of 2016 when I had discovered the Coursera course, "Learning how to learn". Now, I am revisiting the material and just finishing with the accompanying book, which I did not purchase initially.
Some of the most important concepts that I implemented into my daily habits over the past year are:
- using a pomodoro timer to overcome procrastination
- thinking more about putting concepts into simple terms
- using the focused and diffuse modes of thinking effectively
- making exercise a more consistent part of my weekly routine
Going into another semester at school, I realize it is especially important to brush up on learning how to learn skills. I do not want to waste time learning ineffectively or overlook simple principles that help deep learning happen. I am loosely formulating an action plan in my mind.
One of the most exciting techniques I had forgotten about is the 'Memory Palace'.  In reality, memorization is important for learning and building 'chunks' of knowledge. The memory palace technique taps into humans' innate super viso-spacial memory. As hunter-gatherers, we needed to memorize complex journeys between habitats and hunting grounds, along with many guiding reference points. In essence, if we associate familiar space where we live and spend time in vibrantly with things that we need to remember, we can make deeper connections in our memory. To put the memory palace into practice, I plan to associate places and lankmarks around campus with concepts, principles, and formulas. I also plan to post key notes around the walls of my room.
There was an exceptionally smart girl in the same year as me in high school who I stumbled across with at the library around final exam time. She was making up her own test questions and quizzing her friends with them. At the time I was thoroughly impressed but it is only now that I realize just how brilliant her methods were. The habit of frequently testing oneself is one that I also plan to employ this semester.
There is much more to talk about, but I would highly recommend the book, A Mind For Numbers by Barbara Oakley.

Adding Additional Terms (Hierarchical Vocabulary)
How to add terms to a hierarchical vocabulary using the Taxonomy Manager module.
Important. The first term for a vocabulary requires a different process. See "Adding the First Term (Hierarchical Vocabulary)"
- Navigate to Admin > Advanced Settings > Taxonomy - OR - Go to a Taxonomy Manager module.
- Click the Edit link beside the vocabulary for this term. This opens the Edit Vocabulary page.
- Click the Add New button. This displays the Create New Term section.
- In the Create New Term section, complete these fields:
- In the Name text box, enter a name for this term.
- In the Description text box, enter a description for this term.
- At Parent Term, select the parent term for this term.
- Click the Save button. The new term is now displayed in the Terms hierarchical list.
- Repeat Steps 3-5 to add additional terms.
As an example, in the below image, the first term added was called Products. Two additional terms called Dolls and Wooden Toys were added next. Finally, this image displays the term Blocks being added to the parent category Wooden Toys.
The newly added hierarchical term


pipe systems
A piping system can vary in its complexity and distance. Water will need to be directed to your fields, it may change in pressure or split into multiple lines. In order to accomplish all this a combination of pipe, fittings, spools and valves are used to control and regulate the flow of water.
- HDPE Pipe
- P.I.P
- C900 Pipe
- Corrugated Pipe
- PVC Irrigation Pipe
- Steel Pipe


The possibility of implementing PoP into other chains is questionable as of now since the code is closed soruce. If resolved, Veriblock will become all-round the best solution against 51% attacks on the market through it’s model, which not only protects chains against attacks, but also rewards for doing so in a decentralized fashion with proper market incentives.

Contains sorting Comparators.
These functions take any parameters but require only the first to, so they are suitable
for passing to Array.sort(), or with a flex Sort object. Note that returning values other
than 1, 0, or -1 confuse a flex Sort object.
In general, these functions don't handle sorting undefined, it will be coerced to null.
public static function compareBooleans(v1:Boolean, v2:Boolean, ... ignored):int
Compares two Boolean values.
Parameters
| v1:Boolean |
| |
| v2:Boolean |
| |
| ... ignored |
Returns
public static function compareComparables(c1:Comparable, c2:Comparable, ... ignored):int
A standard Comparator for comparing Comparable values.
Parameters
Returns
public static function compareEnumsByName(e1:Enum, e2:Enum, ... ignored):int
Compare two Enums by their name().
If your Enum doesn't override toString(), then you could just use compareStrings.
Parameters
Returns
public static function compareInts(v1:int, v2:int, ... ignored):int
Compares two int values in an overflow safe manner.
Parameters
| v1:int |
| |
| v2:int |
| |
| ... ignored |
Returns
public static function compareNumbers(v1:Number, v2:Number, ... ignored):int
Compares two Number values, taking into account the intricacies of dealing with NaN.
Parameters
| v1:Number |
| |
| v2:Number |
| |
| ... ignored |
Returns
public static function compareStrings(s1:String, s2:String, ... ignored):int
Compare two objects by their toString() values, case sensitively.
Yes, you can pass any objects to this function, and actionscript will coerce them
to Strings, calling toString() if not a simple type.
Parameters
| s1:String |
| |
| s2:String |
| |
| ... ignored |
Returns
public static function compareStringsInsensitively(s1:String, s2:String, ... ignored):int
Compare two objects by their toString().toLowerCase() values, case insensitively.
Yes, you can pass any objects to this function, and actionscript will coerce them
to Strings, calling toString() if not a simple type.
Parameters
| s1:String |
| |
| s2:String |
| |
| ... ignored |
Returns
public static function compareUnknowns(o1:Object, o2:Object, ... ignored):int
Compare two values whose type is not known at compile type. Tries to figure it out.
Also handles nulls.
Note that this method may look like it can safely compare heterogeneous types,
but it cannot. Consider the array: [ true, "meerkat", false ].
compareUnknowns(true, "meerkat") returns -1;
compareUnknowns("meerkat", false) returns -1;
but compareUnknowns(true, false) returns 1, which violates transitivity.
If in doubt, try using createNullSafe(compareStrings), which can safely and consistently
sort anything.
Parameters
| o1:Object |
| |
| o2:Object |
| |
| ... ignored |
Returns
public static function createFields(sortFields:Array, defaults:Array = null):Function
Create a Comparator function that sorts according to one or more fields of Objects.
Array.sortOn() only works with public variables, and not with public getters. This
implementation works with both.
Parameters
| sortFields:Array |
| |
| defaults:Array (default = null )
|
Returns
public static function createFor(clazz:Class):Function
Create a Comparator appropriate for comparing objects of the specified class.
If an appropriate comparator cannot be determined, compareUnknowns is returned.
Parameters
Returns
public static function createNullSafe(comparator:Function):Function
Compose another comparator into one that can compare null and non-null elements
safely, sorting the nulls to the bottom.
Parameters
Returns
Example
Arrays.sort(myStringArray, Comparators.createNullSafe(Comparators.compareStrings));
public static function createReverse(comparator:Function):Function
Create a Comparator function that reverses the ordering of the specified Comparator.
Parameters
Returns
