Overview of new features in Apache HTTP Server 2.0
This document describes some of the major changes between the
1.3 and 2.0 versions of the Apache HTTP Server.
See also
- Unix Threading
- On Unix systems with POSIX threads support, Apache httpd can
now run in a hybrid multiprocess, multithreaded mode. This
improves scalability for many, but not all configurations.
- New Build System
- The build system has been rewritten from scratch to be
based on
autoconf
and libtool
.
This makes Apache httpd's configuration system more similar to
that of other packages.
- Multiprotocol Support
- Apache HTTP Server now has some of the infrastructure in place to
support serving multiple protocols.
mod_echo
has
been written as an example.
- Better support for non-Unix
platforms
- Apache HTTP Server 2.0 is faster and more stable on non-Unix
platforms such as BeOS, OS/2, and Windows. With the
introduction of platform-specific multi-processing modules (MPMs) and the
Apache Portable Runtime (APR), these platforms are now
implemented in their native API, avoiding the often buggy and
poorly performing POSIX-emulation layers.
- New Apache httpd API
- The API for modules has changed significantly for 2.0.
Many of the module-ordering/-priority problems from 1.3 should
be gone. 2.0 does much of this automatically, and module ordering
is now done per-hook to allow more flexibility. Also, new calls
have been added that provide additional module capabilities
without patching the core Apache HTTP Server.
- IPv6 Support
- On systems where IPv6 is supported by the underlying
Apache Portable Runtime library, Apache httpd gets IPv6 listening
sockets by default. Additionally, the
Listen
, NameVirtualHost
, and VirtualHost
directives support
IPv6 numeric address strings (e.g., "Listen [2001:db8::1]:8080
").
- Filtering
- Apache httpd modules may now be written as filters which act on
the stream of content as it is delivered to or from the
server. This allows, for example, the output of CGI scripts to
be parsed for Server Side Include directives using the
INCLUDES
filter in mod_include
. The
module mod_ext_filter
allows external programs to
act as filters in much the same way that CGI programs can act as
handlers.
- Multilanguage Error Responses
- Error response messages to the browser are now provided in
several languages, using SSI documents. They may be customized
by the administrator to achieve a consistent look and feel.
- Simplified configuration
- Many confusing directives have been simplified. The often
confusing
Port
and BindAddress
directives
are gone; only the Listen
directive is used for IP address binding; the ServerName
directive specifies the
server name and port number only for redirection and vhost
recognition.
- Native Windows NT Unicode Support
- Apache httpd 2.0 on Windows NT now uses utf-8 for all filename
encodings. These directly translate to the underlying Unicode
file system, providing multilanguage support for all Windows
NT-based installations, including Windows 2000 and Windows XP.
This support does not extend to Windows 95, 98 or ME, which
continue to use the machine's local codepage for filesystem
access.
- Regular Expression Library Updated
- Apache httpd 2.0 includes the Perl
Compatible Regular Expression Library (PCRE). All regular
expression evaluation now uses the more powerful Perl 5
syntax.
mod_ssl
- New module in Apache httpd 2.0. This module is an interface
to the SSL/TLS encryption protocols provided by
OpenSSL.
mod_dav
- New module in Apache httpd 2.0. This module implements the HTTP
Distributed Authoring and Versioning (DAV) specification for
posting and maintaining web content.
mod_deflate
- New module in Apache httpd 2.0. This module allows supporting
browsers to request that content be compressed before delivery,
saving network bandwidth.
mod_auth_ldap
- New module in Apache httpd 2.0.41. This module allows an LDAP
database to be used to store credentials for HTTP Basic
Authentication. A companion module,
mod_ldap
provides connection pooling and results caching.
mod_auth_digest
- Includes additional support for session caching across
processes using shared memory.
mod_charset_lite
- New module in Apache httpd 2.0. This experimental module allows
for character set translation or recoding.
mod_file_cache
- New module in Apache httpd 2.0. This module includes the
functionality of
mod_mmap_static
in Apache HTTP
Server version 1.3, plus adds further caching abilities.
mod_headers
- This module is much more flexible in Apache httpd 2.0. It can now
modify request headers used by
mod_proxy
, and
it can conditionally set response headers.
mod_proxy
- The proxy module has been completely rewritten to take
advantage of the new filter infrastructure and to implement a
more reliable, HTTP/1.1 compliant proxy. In addition, new
configuration sections provide more readable (and internally
faster) control of proxied sites; overloaded
configuration are not supported. The module
is now divided into specific protocol support modules including
proxy_connect
, proxy_ftp
and
proxy_http
.
mod_negotiation
- A new
ForceLanguagePriority
directive can be used to assure that
the client receives a single document in all cases, rather than
NOT ACCEPTABLE or MULTIPLE CHOICES responses. In addition, the
negotiation and MultiViews algorithms have been cleaned up to
provide more consistent results and a new form of type map that
can include document content is provided.
mod_autoindex
- Autoindex'ed directory listings can now be configured to
use HTML tables for cleaner formatting, and allow finer-grained
control of sorting, including version-sorting, and wildcard
filtering of the directory listing.
mod_include
- New directives allow the default start and end tags for SSI elements
to be changed and allow for error and time format configuration
to take place in the main configuration file rather than in the
SSI document. Results from regular expression parsing and grouping
(now based on Perl's regular expression syntax) can be retrieved
using
mod_include
's variables $0
.. $9
.
mod_auth_dbm
- Now supports multiple types of DBM-like databases using the
AuthDBMType
directive.

In your Bible, look up Matthew 16. Notice that there is only one verse separating the passage you read yesterday (Matthew 16:13-20) from today’s passage (Matthew 16:21-23).
Read Matthew 16:13-20. Then read Matthew 16:21-23.
How would you describe the atmosphere of each passage?
How do you think Peter felt at the end of each passage?
Peter’s first outburst meant that he recognized Jesus as the Messiah when others (even those close to Jesus) had no clue. Peter’s second, disruptive outburst had him standing squarely in Jesus’ path, blocking the way to God’s mission on earth. Although God’s people had been waiting and hoping for a Messiah for thousands of years, their understanding of what the Messiah would do never included suffering or death by crucifixion, something reserved for the most scandalous criminals.
What was Jesus explaining to the disciples in Matthew 16:21?
Why do you think Peter reacted the way he did?
What did Jesus say was the source of Peter’s point of view in verse 23?
How does that contrast with the source of Peter’s knowledge in the previous passage (v. 17)?
Read Isaiah 55:8-9. What do these verses say about the difference between the mind of God and the minds of people?

SATURDAY NIGHT FEVER (1977) A Film Review by Ted Prigge Copyright 1997 Ted Prigge
Director: John Badham Writer: Norman Wexler (from a story by Nik Cohn) Starring: John Travolta, Karen Lynn Gorney, Donna Pescow, Barry Miller, Martin Shakur, Fran Drescher
Anyone who knows me knows that I adore this movie almost as much as I adore, say, "Pulp Fiction." Ever since I finally saw this, I could recite the movie, call the dances (I can't actually do them, 'cause I look like Ed Grimley when I do), and even do the cool walk in the beginning. But even though some might call this a "guilty pleasure," this is actually a very well-made film that could have been a shallow dance movie starring that guy from "Welcome Back, Kotter," but turns out to be a very intelligent character study that just happens to have some of the coolest dance scenes ever made. I know Gene Siskel will back me up on this one.
John Travolta, fresh off of "Kotter" and "Carrie," in the role that made him a superstar (and also spawned a stupid sequel I have yet to see), plays Tony Manero, a kind of dim Brooklynite who works in a paint store during the week, and on Saturday nights, goes out with his friends to the local disco place, the nicely named "2001 Odyssey," where he's a superstar since he takes up the dance floor whenever a cool tune comes on (usually a Bee Gees tune, who wrote about six tunes in a week for this flick).
One night, he sees a woman there (Donna Gorney), who is a great dancer and catches his attention. After he meets her, she turns out to be kind of feisty and a little too intelligent for him, but he persits. Meanwhile, his other partner (Donna Pescow), who has a big crush on him and begs him for sex constantly, is dumped by him cruelly so he can pursue a hopefully more than kosher relationship with Gorney. Also, his brother, who was a priest and the pride of the family, has quit the parish, and is moving on, shaming the family, and making Tony feel better.
Like all dance flicks, there's a big dance competition, and Tony and Gorney want to go and win. But this film is too intelligent, and ends in a kind of mature and shocking manner. Throughout the film, Tony matures (he's only 19), not only in intellect, but in just an all-around kind of way. Like Renton in "Trainspotting," he grows out of his friends, who are self-destructive and totally immature. I mean, these guys go onto the Brooklyn Bridge, dance on the sides, and pretend to fall to their death.
Of course, the big thing to admire in this is the dance scenes, which are totally awesome. I mean, I usually don't get into big dance sequences, but I mean, I'm just all into the ones in this one. And, you also get to see John Travolta in his first Oscar-nominated role. He's an incredible actor and is just incredible, even if he has a Brooklyn accent. He creates a character with many levels, who actually seems more human than he would in a lesser film. Also look for great performances from Gorney and Pescow.
Also, look for a cameo from Fran Drescher (she has weird hair) as a chick who goes up to him, says a memorable line, and even gets to grab his ass, which she revels in even these days.
"Saturday Night Fever" is one of the most memorable and entertaining (not to mention addictive) films I've ever seen. It's not the most brilliant film, but it's certainly one of the more intelligent dance films.

Working with selection
To work efficiently, you must occasionally specify a particular part of a layer that you'd like to manipulate—to copy, delete, move, isolate, or any number of other things. Pixen has excellent selection capabilities, providing support for irregular (multiple) selection. Here's what a selection might look like in a typical document:
While a selection is active, you can only draw inside of it. You can translate the selection marquee itself by clicking inside of it and dragging while any of the selection tools are active. If you'd like instead to move everything inside the selected region, the move tool can help you.

v0.0.1
A janky-ish, in-development, web-framework. If you have VSCode most of the hard setup has been done for you, just download the example project and get started. In the example project you will find I have predefined two helpful VSCode snippets, cfa and cfc. cfa creates a template for a Framer Application and cfc creates a template for a Framer Component.


libapreq - Apache Request C Library
table *data = req->parms; ap_table_set(data, "Key", "Value");
int status; ApacheRequest *req = ApacheRequest_new(r);
req->post_max = 1204; if((status = ApacheRequest_parse(req)) != OK) { char *errmsg = ap_table_get(r->notes, "error-notes"); ... return status; }
int status; ApacheRequest *req = ApacheRequest_new(r);
req->disable_uploads = 1; if((status = ApacheRequest_parse(req)) != OK) { char *errmsg = ap_table_get(r->notes, "error-notes"); ... return status; }
char dir[] = "/usr/tmp"; req->temp_dir = dir;
req->hook_data = (void *) data; req->upload_hook = (int(*)(void*,char*,int,ApacheUpload*)) func;
In this case
func(req->hook_data,buffer,bufsize,upload);
will be called repeatedly during the file upload instead of writing the data to a temp file.
This function creates a new ApacheRequest object using the given request_rec structure:
ApacheRequest *req = ApacheRequest_new(r);
If the request method is GET or POST, the query string arguments and the client form data will be read, parsed and saved. In addition, if the request method is POST and the Content-type is multipart/form-data, the uploaded files will be written to temporary files which can be accessed with the upload field names. The return value is OK on success, otherwise an error code that your handler should return.
This function will return the value of the given parameter key:
const char *value = ApacheRequest_param(req, "Key");
This function will return an array_header of values for the given parameter key:
array_header *values = ApacheRequest_params(req, "Key");
This function will format multi-value parmeters into a comma delimited string.
char *list = ApacheRequest_params_as_string(req, "Key");
If the request Content-type was that of multipart/form-data, this will return an ApacheUpload pointer containing the upload data, NULL otherwise. See ApacheUpload.
ApacheUpload *upload = ApacheRequest_upload(req);
The ApacheUpload structure holds all information for all uploaded files and is accessed via the upload field of an ApacheRequest structure.
char *name = upload->name;
char *filename = upload->filename;
FILE *fp = upload->fp;
char *tempname = upload->tempname;
long size = upload->size;
table *info = upload->info; const char *type = ap_table_get(info, "Content-type");
ApacheUpload *uptr; for (uptr = ApacheRequest_upload(req); uptr; uptr = uptr->next) { char *name = uptr->name; FILE *fp = uptr->fp; ... }
Returns the ApacheUpload pointer associated with name or NULL if name is not found in the list:
ApacheUpload *upload = ApacheUpload_find(upload, name);
Shortcut for accessing the info table:
const char *type = ApacheUpload_info(upload, "Content-Type");
Shortcut for accessing the uploaded file Content-Type:
const char *type = ApacheUpload_type(upload);
This function creates a new ApacheCookie object, using the given request_request and optional attribute arguments which are as follows:
Example:
ApacheCookie *c = ApacheCookie_new(r, "-name", "foo", "-value", "bar", "-expires", "+3M", "-domain", ".cp.net", "-path", "/mypath/database", "-secure", "On", NULL);
This function is used to get or set a cookie attribute pair, accepting the same attributes as the list above. Example:
char *name = ApacheCookie_attr(c, "-name"); /* same as c->name */ (void *)ApacheCookie_attr(c, "-expires", "+3h");
This function parses the given data string or the incoming Cookie header, returning an ApacheCookieJar of ApacheCookie objects.
Example:
int i; ApacheCookieJar *cookies = ApacheCookie_parse(r, NULL); for (i = 0; i < ApacheCookieJarItems(cookies); i++) { ApacheCookie *c = ApacheCookieJarFetch(cookies, i); int j; for (j = 0; j < ApacheCookieItems(c); j++) { char *name = c->name; char *value = ApacheCookieFetch(c, j); ... } }
The number of values for the given cookie.
The nth value for the given cookie.
Add a new value to the cookie.
The number of cookies in the given cookie jar.
The nth cookie in the given cookie jar.
Add a new cookie to the cookie jar.
This function gets or sets the expiration date for cookie. The following forms are all valid for the time_str parmeter:
+30s 30 seconds from now +10m ten minutes from now +1h one hour from now -1d yesterday (i.e. "ASAP!") now immediately +3M in three months +10y in ten years time Thursday, 25-Apr-1999 00:40:33 GMT at the indicated time & date
Put cookie in the oven to bake. (Add a Set-Cookie header to the outgoing headers table.)
ApacheCookie_bake(c);
Returns a string version of the cookie:
ap_table_add(r->headers_out, "Set-Cookie", ApacheCookie_as_string(c));
This library is based on Perl modules by Lincoln Stein.

Scalability
How to deal with high load?
Scalability
Scale up - give me more!
- Give more CPU to the node...
- Give more memory to the node...
- Give more storage to the node...
Scalability
Scale up - painful consequences
- Need for more and more expensive hardware
- Need for careful resource planning
- Availability issues - backup machine needs to be as fast as production
Scalability
Scale out - let's cluster!
- Use cheap hardware!
- Easily add new nodes!
- Remove/reuse nodes as they are not needed
Clustering
What is cluster?
- Set of connected computers that work together
- ...to improve performance
- ...and availability
- ...and save money!
Consensus
- "fundamental problem in fault-tolerant distributed systems"
- "multiple servers agreeing on values"
- "replicated state machines"
Raft
Consensus algorithm
- Designed as an alternative to overly complicated Paxos
- Strong leadership - flow only from leader to other servers
- Leader election by voting with randomized timers
- Membership changes by using join consensus approach
Raft
Basics
- Server can be in one of three states: Leader, follower, or candidate
- Time is divided into terms, and each term begins with election
- Data is stored as indexed log applied to state machine
- Only two commands: AppendEntries RPC and RequestVote RPC
Raft
Elections
- Leaders send empty AppendEntries (heartbeats) to followers
- If follower doesn't receive heartbeat in randomized timer, convert to candidate
- Candidate increment currentTerm, vote for itself and send RequestVote to all other servers
- If votes received from majority, convert to leader
Raft
Operations
- Leaders receive command from client, write to log and send AppendEntries to followers (in parallel)
- Followers acknowledge command (if agreed on term number and log index)
- When command is replicated to majority, apply to state machine and return result to client
- Raft consensus algorithm
- Key-value distributed data store
- Simple API - JSON on HTTP
- Simple implementation of Raft consensus algorithm
- Multiple discovery methods
- Typical cluster size - 5, 7 or 9 nodes
- Extra nodes can become proxy and can be promoted to follower
Discovery service
$ curl -w "\n" https://discovery.etcd.io/new
https://discovery.etcd.io/6a28e078895c5ec737174db2419bb2f3
- Discovery service stores peer address and initial cluster size
- First node becomes leader
- All following nodes become peers
- Run your own discovery with github.com/coreos/discovery.etcd.io

systemd glossary
unit
is a configuration file that describes the properties of the process that you'd like to run
target
is a grouping mechanism that allows systemd to start up groups of processes at the same time
fleet
"You can think of fleet as an extension of systemd that operates at the cluster level instead of the machine level. Systemd is a single machine init system; fleet is a cluster init system."

Inline vs. Inline-Block
When to use each
June 21, 2015
    The main difference between an inline and an inline block is that an inline has no space above or below it and an inline block has some space on an element on the same line.
    To really know the differences, you have to know what is allowed for both. Inline elements cannot have a width or height, and although they can have left and right margins and padding, they cannot have a top or bottom margin or padding. They can, however, have elements sit next to them. Inline elements are written as "display:inline".
    Inline-block elements are just like inline elements except that inline-block elements can have a width and height assigned to it. It can also have top and bottom margins and padding. Inline-block elements are written as "display:inline-block". Inline-block elements basically have a block shape to it and are given space next to each other while inline elements can overlap each other.

GolemOn a historical basis, it's not hard to see why Jewish people would want a superhero. You can only spend so much time being persecuted before you get tired of it.In medieval times, the persecution was particularly intense and the solution was extreme, or so the story goes. There are several variations on the legend of the Golem, but the most widely known version places the activity in Prague during the 16th century. Our hero is Rabbi Loew, intrepid leader of the Prague Jewish community. According to legend, the Prague Gentiles had wronged the Jews in some way -- the details of the complaint vary, but range anywhere from spreading nasty rumors about drinking the blood of children to an all-out pogrom. To make right this terrible wrong, Rabbi Loew draws on his skills as master of the Kabbalah, a collection of Jewish mystical writings which is considered one of the all-time classics of occultism. He uses instructions found in the Sepher Yetzirah, a book of the Kabbalah, to animate the form of a man made from clay. Rabbi Loew animated the golem by means of a mystical symbol inscribed on a seal that was placed on the golem's forehead (around the area of the "Third Eye" in Eastern mysticism). The magical being came to life, following the orders of its creator... Or that was the plan, anyway. As anyone who has read the Bible knows, it isn't nice to aspire to godhood.  If this story sounds familiar, well, it is. The legend of the golem, and its cautionary tale formed the nugget of a tale which Mary Shelley would eventually rewrite as Frankenstein. While the book version of Frankenstein layers on new elements and a decent amount of creativity, all that was abandoned when the story made its way to Hollywood. Frankenstein and the Golem would battle it out on in the movies for almost 30 years without ever once appearing in the same movie. In 1910, the first adaptation of Frankenstein rolled out in the U.S. to very little fanfare. It ran all of 12 minutes. Versions of the story released to the public in 1915 and 1920 were little better, but both are now lost. Meanwhile, pioneering silent film director Paul Wegener was making his career out of the tale of the Golem to the silver screen as actor-director-writer in The Golem (1916), The Golem and the Dancing Girl (1917) and The Golem As He Came Into The World (1920, prequel to the 1916 version). The first two movies are lost, but the third one is considered something of a classic, with vivid visuals and special effects during the animation of the monster, and a timely message about anti-Semitism that fell on deaf ears in Wegener's native Germany. On the basis of pure cinematic merit, the Golem was kicking Frankenstein's ass pretty convincingly right up through 1931, when Boris Karloff forever seared the image of Victor F's Monster into the psyche of the filmgoing public. It can perhaps be considered a moral victory for the Golem. After all, Karloff's Monster is noticeably derivative of Wegener's Golem in its look, not to mention its behavior. In legend and on film, the Golem is not an intelligent creature. It follows directions at best, and runs around on murderous rampages at worst. Frankenstein's Monster, on the other hand, spouted philosophy and bemoaned its existential woes at great length, at least in the original novel. Karloff was more Wegener than Wegener, and the legacy of the 1931 Frankenstein remains one of the cinema's most enduring. Despite all this, the tale of the Golem has exercised an enduring effect on occultism over the course of centuries, along with related concepts like the Tibetan tupla and the Thelemic homunculus, a magical creation attempted by Aleister Crowley and Jack Parsons (unlike the Golem, the homunculus or moon-child was supposed to be the product of a sex act). Modern science has not, perhaps, absorbed as much of the cautionary tale's caution as one might hope, and occasional efforts at creating artificial life are sometimes named after Rabbi Loew's mythical monster. So far, none of these have gone on killing sprees. But do you really want to push your luck like that? Purists, of course, can always return to the original. The making of the golem is the ultimate test of Kabbalistic skill and a sign of great occult accomplishment. But if you've read the Sepher Yetzirah, you may have noticed that it doesn't seem to include a "how to make a golem" heading, at least not in the sense of "add 300 pounds of clay, stir for 30 minutes then reduce to a simmer and cover, occasionally stirring for two hours." Sepher Yetzirah is a somewhat arcane account of the making of the universe, in which the relationship between Hebrew letters, numbers and mystical concepts are explained in a manner intended to illustrate how God created the universe. It's only when you truly understand all of that, by deciphering the arcane symbolism in the book, that the path to creating your life can be deduced through reverse engineering. After that, there are still two more major obstacles that remain in terms of creating a Golem to do your bidding. First, some traditions hold that only the most righteous of wise men can create a Golem. Obviously, if you're out there tinkering around with creating life for the fun and profit, you would automatically be disqualified from this category. Second, if you have to figure out all the secrets of the creation of the universe before you can figure out how to make a Golem, there's a pretty good chance you won't be so interested in actually having a Golem by the time you're done. Either you'll be so humbled by God's blueprint that you'll lose interest, or the vastness of so much forbidden knowledge will fry your brain into crispy ruination. But then, what else were you going to do with your brain? Be honest.

### Before we start - Install [Google Chrome](https://www.google.co.uk/chrome/) - Install a code text editor like [Atom](https://atom.io/) or [SublimeText](https://www.sublimetext.com/)
## CSS Compositions
## Recap from previous weeks - HTML = Structure - CSS = Style
### Anatomy of CSS
### Box model - `content` - `margin` - `border` - `padding` [Demo](https://mattwolff.github.io/interactive/boxify.html)
### Units of measurement - Pixels `px` are the most straightforward and inflexible - Percentages `%` are flexible and dependent on their parent container - Ems `em` are dependent on whatever `font-size` the `body` is - `vh` and `vw` stand for viewport height and viewport width
### Inline elements Inline elements “go with the flow.” If you put a lot of inline elements together, you’ll notice them flow left to right like text. - `img` - `a` - `span`
### Block elements Block elements "stack one on top of another” … like blocks. - `h1` - `p` - `div`
### CSS Layout and Positioning - Using CSS, you can position items across the page—things don’t have to appear one after the other in succession.
### Position The position property can help you manipulate the location of an element. - `position: static` – default - `position: relative` - `position: absolute` - `position: fixed`
### Position declarations You need to specify where your element will be, e.g.: - `top: 5px` - `right: 0` - `bottom: 20px` - `left: 12px` [Demo](https://developer.mozilla.org/en-US/docs/Web/CSS/position)
### Display Every element on a webpage is a box. The display property determines exactly how that box behaves. - `display: block` — default (depending on element) - `display: inline` — default (depending on element) - `display: inline-block` - `display: none` [Demo](https://www.w3schools.com/cssref/tryit.asp?filename=trycss_display)
### Float The `float` CSS property places an element on the left or right side of its container, allowing text and inline elements to wrap around it. - `float: none` — default - `float: left` - `float: right` [Demo](https://developer.mozilla.org/en-US/docs/Web/CSS/float)
### Clear If an element can fit horizontally in the space next to another element which is floated, it will. Apply `clear` to move the element below instead. - `clear: both` [Demo](https://css-tricks.com/almanac/properties/c/clear/)
### Resetting styles It's a good idea to override default styles to a predictable value using the “universal” CSS selector (*): - `margin: 0;` - `padding: 0;` - `box-sizing: border-box;`
## Workshop 1. Find an abstract composition you like 2. Recreate it in CSS
### Abstract compositions [Arena channel](https://www.are.na/gemma-copeland/css-compositions)
### Resources - [CSS Layout Cheat Sheet](https://learn-the-web.algonquindesign.ca/topics/css-layout-cheat-sheet/) - [The Shapes of CSS](https://css-tricks.com/the-shapes-of-css/) - [CSS Gradients](https://css-tricks.com/css3-gradients/)
### Where to learn more - [Learn Layout](http://learnlayout.com/) - [Interneting is Hard](https://internetingishard.com/html-and-css/css-box-model/) - [Opening the Box Model](https://learn.shayhowe.com/html-css/opening-the-box-model/)
### Next steps - Can you reinterpret the artwork in a digital-first way? - Make it responsive? Interactive? - Can you recreate another artwork? - Can you make a navigation system for moving between your artworks?
### Flexbox and Grid Layout The main idea behind the flex layout is to give the container the ability to alter its items' width/height (and order) to best fill the available space. A flex container expands items to fill available free space, or shrinks them to prevent overflow.
### Learning Flexbox - [Guide to Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/) - [Flexbox Froggy](https://flexboxfroggy.com)

Machine Learning Laboratory Experiences for Introducing
Undergraduates to Artificial Intelligence
|
| OVERVIEW |
|
The popular boardgame Clue
(a.k.a. Cluedo) serves as a fun focus problem for this introduction to
propositional knowledge representation and reasoning. After covering
fundamentals of propositional logic, students first solve basic logic
problems with and without the aid of a satisfiability solver (e.g.
zChaff).
Students then represent the basic knowledge of Clue in order to solve a
Clue mystery. Several possible advanced projects are sketched if
students wish to pursue the topic in more depth. |
| OBJECTIVES |
The object of this project is
to give the student a deep, experiential understanding of propositional
knowledge representation and reasoning through explanation,
worked examples, and implementation exercises.
|
| PREREQUISITES |
| The student should understand the syntax of Java,
Python, or LISP. Students who
program in C++ should be able to follow most of the Java examples. Along with the project, the student should cover the recommended background reading below. In support of the exercises and project, one
should download and install
zChaff,
a complete, DPLL-type SAT solver. If the use of a different SAT
solver is desired, one will need to modify
SATSolver.java accordingly. |
| BACKGROUND |
For a more detailed
introduction to the logical concepts, we recommend the parallel reading of
a good AI textbook section on propositional logic. For example, one
might assign Chapter 7 ("Logical Agents") of:
Students are also encouraged to play the game of
Clue in order to gain a solid understanding of the game and the knowledge one
acquires during play. One can speed gameplay by dispensing with
board movement and allowing each player in turn to make an unrestricted
suggestion and/or accusation. |
| DESCRIPTION |
| The project is described in the
file clue.pdf. You will need the
free Adobe
Acrobat Reader to view this file. Example Java code described in the project is available here (see below for Python and LISP): This code was generated from the same source file that generated clue.pdf using the literate programming tool noweb. We recommend having students do a few of the included logic exercises of Section 7 in order to gain experience with the SATSolver class before beginning work on the ClueReasoner. Students seeking more extended challenges will also find brief descriptions of related advanced projects including basic SAT solver challenges and extensions for cardinality constraints. Daniel Le Berre, Lecturer at the faculté Jean Perrin, Université d'Artois, has generously provided a modified SATSolver for using SAT4J, a library of efficient SAT solvers targeted for first users of SAT "black boxes" in Java. A version that is compatible with SATSolver.java usage above is also available. David Musicant, Associate Professor of Computer Science at Carleton College, has generously provided a LISP port and a Python port of the above project description and source files:

| AFTERWORD |
| In his book Machine Learning, Tom Mitchell writes “A computer is said to learn from experience E with respect to some class of tasks T and performance measure P, if its performance at tasks in T, as measured by P, improves with experience E.” The three “experiences” of deductive learning, inductive learning, and knowledge acquisition can add knowledge to a knowledge base, thus potentially improving (or even making possible) the average expected time performance of the task of answering queries to the knowledge base. This project and the corresponding reading focus on knowledge acquisition and deductive learning. |


#include <unistd.h> char *getcwd(char *buf, size_t size); char *getwd(char *buf); char *get_current_dir_name(void);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
get_current_dir_name():
getwd():
_BSD_SOURCE || (_XOPEN_SOURCE >= 500 || _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED) && !(_POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700)
The getcwd() function copies an absolute pathname of the current working directory to the array pointed to by buf, which is of length size.
If the length of the absolute pathname of the current working directory, including the terminating null byte, exceeds size bytes, NULL is returned, and errno is set to ERANGE; an application should check for this error, and allocate a larger buffer if necessary.
As an extension to the POSIX.1-2001 standard, glibc's getcwd() allocates the buffer dynamically using malloc(3) if buf is NULL. In this case, the allocated buffer has the length size unless size is zero, when buf is allocated as big as necessary. The caller should free(3) the returned buffer.
get_current_dir_name() will malloc(3) an array big enough to hold the absolute pathname of the current working directory. If the environment variable PWD is set, and its value is correct, then that value will be returned. The caller should free(3) the returned buffer.
getwd() does not malloc(3) any memory. The buf argument should be a pointer to an array at least PATH_MAX bytes long. If the length of the absolute pathname of the current working directory, including the terminating null byte, exceeds PATH_MAX bytes, NULL is returned, and errno is set to ENAMETOOLONG. (Note that on some systems, PATH_MAX may not be a compile-time constant; furthermore, its value may depend on the filesystem, see pathconf(3).) For portability and security reasons, use of getwd() is deprecated.
On failure, these functions return NULL, and errno is set to indicate the error. The contents of the array pointed to by buf are undefined on error.
getwd() is present in POSIX.1-2001, but marked LEGACY. POSIX.1-2008 removes the specification of getwd(). Use getcwd() instead. POSIX.1-2001 does not define any errors for getwd().
get_current_dir_name() is a GNU extension.
These functions are often used to save the location of the current working directory for the purpose of returning to it later. Opening the current directory (".") and calling fchdir(2) to return is usually a faster and more reliable alternative when sufficiently many file descriptors are available, especially on platforms other than Linux.


Module polyGen
Use this module to create a polyphonic generator with virtual tracks.
Example at sine-organ.lua.
This module facilitates the creation of polyphonic instruments. It acts as a layer that covers the plugin.processBlock function, receives MIDI notes and dispatches them to virtual tracks. The polyGen.VTrack prototype is exposed for you to define audio processing in a simple, monophonic, per-note fashion. Initialize this module by calling polyGen.initTracks .
The polyGen global is available to every protoplug script after including the main protoplug header :
require "include/protoplug"
Functions
| polyGen.initTracks ([n=8]) | Set up virtual tracks. |
Class polyGen.VTrack

Crack |
(freebase) |
I've been blowing my money recently for something to do on blow. One of my dealers keeps trying to get me to smoke crack with him. He's always on about how much better it is. I've banged coke before, so I figured that I had a pretty good idea of how great it is. I know that I get much higher when I shoot. But I donít care.  It's as simple as that.
Last night though, I caved into my desire to try out this 'crack' and see what all the fuss is about. Addiction was not a concern for me, since I'm probably addicted to coke anyways, and I can't see my body being biased about how it gets it's precious drug. I started out the night blasting abnormally large rails to get truly high on the stuff, instead of just talkative. Eventually IT came up in conversation. Crack. Everyone present knew how to make it except me. So I let them at it while I checked out if they were doing it right online. We ended up with some gross looking yellow paste. For some reason we filled the bowl of the pipe with cigarette ash and threw the crack on top. I was feeling a little bit too high to hit the pipe immediately, although I was talked into it anyways.
I could feel my chest pulsating with what I can only describe as an orgasmic feeling after the first hit, and considered stopping. With the second hit my brain also seemed to pulsate with this weird energy. The third hit did nothing extra so I stopped and passed the pipe. I became extremely disoriented and couldnít focus on the words that people were saying. I managed 'Whoa, I'm fucked!' or something like that, and kinda swayed in my chair for some time waiting for additional effects to kick in. The ambient feeling of well being of my coke high seemed to increase by quite a bit, and stayed like that even after the weird pulsing ended.
I sustained this feeling the best I could by doing more rails. Unfortunately I ran out of coke. So obviously I didn't get a chance to experience the infamous and immediate crack burnout. In fact, it seems I experienced the opposite. Although I've been out of coke for hours now, I am still feeling quite happy albeit dizzy. My desire for more of the stuff is stronger than usual, which is no problem to ignore while I write this. At some point in time after I ran out I also had a vomiting fit. This is abnormal for me, but I'm not used to the low quality of cocaine that I had this night. It was undoubtedly something in the cut that caused this, since people who had the very same stuff, who didnít turn it into crack also suffered from this vomiting when they ran out.
My experience with crack is, therefore, a good one. I won't do it again however. Like I said, I prefer to snort it.

The web service allows users to query the warehouse in several different ways. The Query api presents a single set of methods for starting, using, and closing a query. The web service hosts different types of query logic each with their own response type. Each query has the same lifecycle:
Query logic classes will use different types of syntax for the query string. Most of the queries that retrieve raw events will accept JEXL (default) or our modified LUCENE syntax. We support a subset of the language elements in the Apache Commons JEXL syntax and we have implemented some of our own custom functions. We support the following JEXL operators:
We have created the following functions, see the examples section below to see their usage:
Since JEXL is an expression language and not a text query language, we also added support for unfielded queries. For most of the query logic types that query raw events, we have provided the capability to search on any indexed field. To achieve this, the user should submit their query with the field name: _ANYFIELD_. See the examples below for its usage.
We have modified the LUCENE syntax such that the NOT operator is not unary, AND's are not fuzzy, and the implicit operator is the AND not the OR. Our LUCENE syntax has the following form:
ModClause ::= DisjQuery [NOT DisjQuery]* DisjQuery ::= ConjQuery [ OR ConjQuery ]* ConjQuery ::= Query [ AND Query ]* Query ::= Clause [ Clause ]* Clause ::= Term | [ ModClause ] Term ::= field:selector | field:selec* | field:selec*or | field:*lector | field:selec?or | selector | (can use wildcards) field:[begin TO end] | field:{begin TO end} | "quick brown dog" | "quick brown dog"~20 | #FUNCTION(ARG1, ARG2)
Note that to search for punctuation characters within a term, you need to escape it with a backslash.
We have also modified the LUCENE syntax to provide support for the JEXL syntax that LUCENE does not support. The table below maps the
JEXL operators to the supported LUCENE syntax:
| JEXL Operator | LUCENE Operator |
|---|---|
| filter:includeRegex(regex) | #INCLUDE(regex) |
| filter:includeRegex(field, regex) | #INCLUDE(field, regex) |
| filter:includeRegex(field1, regex1) <op> filter:includeRegex(field2, regex2) ... | #INCLUDE(op, field1, regex1, field2, regex2 ...) where op is 'or' or 'and' |
| filter:excludeRegex(regex) | #EXCLUDE(regex) |
| filter:excludeRegex(field, regex) | #EXCLUDE(field, regex) |
| filter:excludeRegex(field1, regex1) <op> filter:excludeRegex(field2, regex2) ... | #EXCLUDE(op, field1, regex1, field2, regex2 ...) where op is 'or' or 'and' (note: the op provided in the LUCENE query will be reversed for the JEXL intersection of the same query) |
| filter:isNull(field) | #ISNULL(field) |
| not(filter:isNull(field)) | #ISNOTNULL(field) |
| filter:occurrence(field,operator,count)) | #OCCURRENCE(field,operator,count) |
| filter:timeFunction(field1,field2,operator,equivalence,goal) | #TIME_FUNCTION(field1,field2,operator,equivalence,goal) |
| filter:text(field) | #TEXT(field) |
| filter:text(field, value) | #TEXT(field, value) |
| filter:text(field1, value1) <op> filter:text(field2, value2) ... | #TEXT(op, field1, value1, field2, value2 ...) where op is 'or' or 'and' |
| filter:compare(field1, op, mode, field2) | #COMPARE(field1, op, mode, field2) where op is '>', '>=', '<', '<=', '==', '=', or '!=' and mode is 'ALL' or 'ANY' |
Notes:
Some geo functions are supplied as well that may prove useful although the within_bounding_box function may be done with a simple range comparison (i.e. LAT_LON_USER <= <lat1>_<lon1> and LAT_LON_USER >= <lat2>_<lon2>.
| JEXL Operator | LUCENE Operator |
|---|---|
| geo:within_bounding_box(latLonField, lowerLeft, upperRight) | #GEO(bounding_box, latLonField, 'lowerLeft', 'upperRight') |
| geo:within_bounding_box(lonField, latField, minLon, minLat, maxLon, maxLat) | #GEO(bounding_box, lonField, latField, minLon, minLat, maxLon, maxLat) |
| geo:within_circle(latLonField, center, radius) | #GEO(circle, latLonField, center, radius) |
Notes:
New GeoWave geo functions are available as follows:
| JEXL Operator | LUCENE Operator |
|---|---|
| geowave:intersects_bounding_box(geometryField, westLon, eastLon, southLat, northLat) | #INTERSECTS_BOUNDING_BOX(geometryField, westLon, eastLon, southLat, northLat) |
| geowave:intersects_radius_km(geometryField, centerLon, centerLat, radiusKm) | #INTERSECTS_RADIUS_KM(geometryField, centerLon, centerLat, radiusKm) |
| geowave:contains(geometryField, Well-Known Text) | #CONTAINS(geometryField, centerLon, centerLat, radiusDegrees) |
| geowave:covers(geometryField, Well-Known Text) | #COVERS(geometryField, Well-Known Text) |
| geowave:coveredBy(geometryField, Well-Known Text) | #COVERED_BY(geometryField, Well-Known Text) |
| geowave:crosses(geometryField, Well-Known Text) | #CROSSES(geometryField, Well-Known Text) |
| geowave:intersects(geometryField, Well-Known Text) | #INTERSECTS(geometryField, Well-Known Text) |
| geowave:overlaps(geometryField, Well-Known Text) | #OVERLAPS(geometryField, Well-Known Text) |
| geowave:within(geometryField, Well-Known Text) | #WITHIN(geometryField, Well-Known Text) |
Notes:
An #EVALUATION_ONLY function has recently been introduced which is intended to be used to defer execution of part of a query to the evaluation phase. This could be used to defer a range to the evaluation phase, or possibly to defer GeoWave function evaluation to the evaluation phase, avoiding the need to generate geo indices when additional indexed fields are present (i.e. indexed fields other than the geo field). For example:
| JEXL Example |
|---|
| INDEXED_FIELD == 'some value' && ((ASTEvaluationOnly = true) && geowave:intersects(geometryField, Well-Known Text)) |
| LUCENE Example |
| INDEXED_FIELD: 'some value' AND #EVALUATION_ONLY('#INTERSECTS(geometryField, Well-Known Text)') |
There are some additional functions that are supplied to handle dates more smoothly. It is intended that the need for these functions may go away in future versions (bolded parameters are literal, other parameters are substituted with appropriate values):
| JEXL Operator | LUCENE Operator |
|---|---|
| filter:betweenDates(field, start date, end date) | #DATE(field, start date, end date) or #DATE(field, between, start date, end date) |
| filter:betweenDates(field, start date, end date, start/end date format) | #DATE(field, start date, end date, start/end date format) or #DATE(field, between, start date, end date, start/end date format) |
| filter:betweenDates(field, field date format, start date, end date, start/end date format) | #DATE(field, field date format, start date, end date, start/end date format) or #DATE(field, between, field date format, start date, end date, start/end date format) |
| filter:afterDate(field, date) | #DATE(field, after, date) |
| filter:afterDate(field, date, date format) | #DATE(field, after, date, date format) |
| filter:afterDate(field, field date format, date, date format) | #DATE(field, after, field date format, date, date format) |
| filter:beforeDate(field, date) | #DATE(field, before, date) |
| filter:beforeDate(field, date, date format) | #DATE(field, before, date, date format) |
| filter:beforeDate(field, field date format, date, date format) | #DATE(field, before, field date format, date, date format) |
| filter:betweenLoadDates(LOAD_DATE, start date, end date) | #LOADED(start date, end date) or #LOADED(between, start date, end date) |
| filter:betweenLoadDates(LOAD_DATE, start date, end date, start/end date format) | #LOADED(start date, end date, start/end date format) or #LOADED(between, start date, end date, start/end date format) |
| filter:afterLoadDate(LOAD_DATE, date) | #LOADED(after, date) |
| filter:afterLoadDate(LOAD_DATE, date, date format) | #LOADED(after, date, date format) |
| filter:beforeLoadDate(LOAD_DATE, date) | #LOADED(before, date) |
| filter:beforeLoadDate(LOAD_DATE, date, date format) | #LOADED(before, date, date format) |
| filter:timeFunction(DOWNTIME, UPTIME, '-', '>',<PHONE_NUMBER>000L) | #TIME_FUNCTION(DOWNTIME, UPTIME, '-', '>', '2522880000000L') |
Notes:
In queries, unique functions are available to find unique results for fields that are specified, to the granularity of YEAR, MONTH, DAY, HOUR, MINUTE, SECOND, TENTH or MILLISECOND. The field passed to the function needs to be a dateTime field if using a time granularity, otherwise the original field will be returned as a unique result. Multiple granularity levels can be provided to the same field in multiple ways, and granularities will be merged across multiple functions if necessary. Potential function options that the user may use are listed below.
As referenced above, multiple granularity levels can be specified for the same field in different ways. The following queries are equivalent, and will find each unique result for field, to the hour and to the minute specified:
In queries where hits are found against phrases using the content:phrase, content:adjacent, and content:within functions, expanded versions of the phrases may be retrieved using the excerpts feature, either via the #excerpt_field query function, or the excerpt.fields query parameter. The field passed to the function must correspond to a field in which a phrase was targeted, and the offset indicates the number of additional words the phrase will be expanded by at the beginning and end of the phrase. The expanded phrases will be available within the HIT_EXCERPT attribute of returned documents.

A related function that is very useful is ifelse
. This function takes three arguments: a logical and two possible answers. If the logical is TRUE
, the value in the second argument is returned and if FALSE
, the value in the third argument is returned. Here is an example:
a <- 0
ifelse(a > 0, 1/a, NA)
#> [1] NA
The function is particularly useful because it works on vectors. It examines each entry of the logical vector and returns elements from the vector provided in the second argument, if the entry is TRUE
, or elements from the vector provided in the third argument, if the entry is FALSE
.
a <- c(0,1,2,-4,5)
result <- ifelse(a > 0, 1/a, NA)
This table helps us see what happened:
| a | is_a_positive | answer1 | answer2 | result |
|---|---|---|---|---|
| 0 | FALSE | Inf | NA | NA |
| 1 | TRUE | 1.00 | NA | 1.0 |
| 2 | TRUE | 0.50 | NA | 0.5 |
| -4 | FALSE | -0.25 | NA | NA |
| 5 | TRUE | 0.20 | NA | 0.2 |
vec <- c(1:5, NA, 6:11, NA, 21, NA, 3:5)
# Check the pre-defined variable 'vec'.
head(vec)
# Find the total number of NA in vec.
sum(is.na(vec))
# when a value in vec is NA, change NA to 0 and save it into vec_noNA.
vec_noNA <- ifelse(is.na(vec), ,)
# Find the total number of NA in vec_noNA
sum(is.na(vec_noNA))
# Check the pre-defined variable 'vec'.
head(vec)
# Find the total number of NA in vec.
sum(is.na(vec))
# when a value in vec is NA, change NA to 0 and save it into vec_noNA.
vec_noNA <- ifelse(is.na(vec), 0, vec)
# Find the total number of NA in vec_noNA
sum(is.na(vec_noNA))
msg <- "Please see that objects are well-defined and correct."

7.4 Allocating Objects to Cache DirectoriesWhen Squid wants to store a cachable response on disk, it calls a function that selects one of the cache directories. It then opens a disk file for writing on the selected directory. If, for some reason, the open( ) call fails, the response isn't stored. In this case, Squid doesn't try opening a disk file on one of the other cache directories. Squid has two of these cache_dir selection algorithms. The default algorithm is called least-load; the alternative is round-robin. The least-load algorithm, as the name implies, selects that cache directory that currently has the smallest workload. The notion of load depends on the underlying storage scheme. For the aufs, coss, and diskd schemes, the load is related to the number of pending operations. For ufs, the load is constant. For cases in which all cache_dirs have equal load, the algorithm uses free space and maximum object sizes as tie-breakers. The selection algorithm also takes into account the max-size and read-only options. Squid skips a cache directory if it knows the object size is larger than the limit. It also always skips any read-only directories. The round-robin algorithm also uses load measurements. It always selects the next cache directory in the list (subject to max-size and read-only), as long as its load is less than 100%. Under some circumstances, Squid may fail to select a cache directory. This can happen if all cache_dirs are overloaded or if all have max-size limits less than the size of the object. In this case, Squid simply doesn't write the object to disk. You can use the cache manager to track the number of times Squid fails to select a cache directory. View the store_io page (see Section <IP_ADDRESS>), and find the create.select_fail line. |

The Push Messaging server responds with HTTP status code 500
(internal server error) if the app that calls the pushMessaging API
is not found in the Chrome Web Store. This ownership check
is designed to prevent people from sending messages to your app
without your permission. Commonly this error occurs during
development if you run a version of your app without the correct
key
attribute in its manifest file.
To fix this problem, simply install your app from
the Chrome Web Store and copy the key
field from manifest.json in the installed app to manifest.json in
the version of the app that you are developing
(see Testing in the cloud for
detailed instructions). Note that you need to remove the key
field from manifest.json before you upload the app to the Chrome Web Store again.

THE HAUNTED WIDOWER
A LABOURING man, very shortly after his wife's death, .sent to a servant girl, living at the time in a small shipping port, requesting her to come to the inn to him. The girl went, and over a "ha' pint" she agreed to accept him as her husband.
All went on pleasantly enough for a time. One evening the man met the girl. He was silent for some time and sorrowful, but at length he told her his wife had come back.
"What do'st mean?" asked the girl; "have 'e seen hur?"
"Naw, I han't seed her."
"Why, how do'st knaw it is her then?"
The poor man explained to her, that at night, when in bed, she would come to the side of it, and "flop" his face; and there was no mistaking her "flop."
"So you knawed her flop, did 'e?" asked the girl.
"Ay, it couldn't be mistook."
"If she do hunt thee," said the girl, "she 'II hunt me; and if she do flop 'e, she 'II flop me,--so it must be off atween us."
The unfortunate flop of the dead wife prevented the man from securing a living one.

Alphabet
The Esperanto alphabet consists of 28 letters: a, b, c, ĉ, d, e, f, g, ĝ, h, ĥ, i, j, ĵ, k, l, m, n, o, p, r, s, ŝ, t, u, ŭ, v, z.
Note the following differences from English:
- a as in "father"
- c = ts as in "Betsy"
- ĉ = ch as in "church"
- e as in "there"
- g as in "give"
- ĝ as in "judge"
- h as in "hammer"
- ĥ = Scottish ch as in "Loch"
- i as in "machine"
- j = y as in "yes". aj, ej, oj, uj are diphtongs consisting respectivel of a, e, o, u plus a short i-sound. Thus
- aj = i in "die"
- ej = a in "face"
- oj = oy in "boy"
- uj = ui in "ruin", prnounced quickly.
- ĵ = zh as in "measure"
- o as in "north"
- r is always pronounced – ideally, rolled
- s as in "sense"
- ŝ = sh in "sharp"
- u as in "fool"
- ŭ = w as in "tower". aŭ, eŭ are diphtongs consisting respectively of "a" or "e" plus a short oo-sound. Thus
- aŭ = ou in "mouth"
- eŭ is as "eh-oo".
Pronunciation
Words are pronounced exactly as spelled, applying the equivalents mentioned above, e.g.
- amiko = ah-MEE-koh
- ĉambro = CHAHM-broh
- ĝi = jee.
Stress
Words of more than one syllable are stressed on the last syllable but one, e.g.
- te-le-FO-no (teh-leh-FOH-noh)
- ra-DI-o (rah-DEE-oh)
- kaj (kigh)
- a-MI-ko (ah-MEE-koh)
- ES-tas (ESS-tahss).
- NB: AN-kaŭ (because kaŭ is a single syllable).
Be careful over words like historio (hi-sto-RI-o, hee-stoh-REE-oh).
Article
The definite article is la (– *the). It is invariable (no change for gender, case or number). There is no indefinite article:
- la amiko – the friend
- la laboro – the work
Personal Pronouns
- mi – I
- vi – you
- li – he
- ŝi – she
- ĝi – ĝi
- ni – we
- ili – they
The pronouns li, ŝi, ĝi are used in just the same way as English "he, she, it".
Possessive Pronouns
These are formed by adding the ending a to the simple pronouns:
- mia – my
- via – your
- lia – his
- ŝia – her
- ĝia – its
- nia – our
- ilia – their
Nouns
All nouns end in -O. There is no grammatical gender: where appropriate, feminine sex is indicated by a suffix.
- tablo – table
- lernanto – learner
- lernantino – learner (female)
Plural
The plural ending is j. Both nouns and adjectives take this ending, e.g.:
- tabloj – tables
- lernantoj – learners
- viaj lernantoj – your learners
Verbs
- The infinitive ending is -i, e.g.
- lerni – to learn
- labori – to work
- esti – to be.
- The present tense ending is -as. It is the same for all persons and numbers:
- mi sidas – I sit
- vi sidas – you sit
- ni sidas – we sit
- ili sidas – they sit.
Ĉu?
This is an interrogative particle, used to turn a statement into a yes/no question:
- Ĉu vi sidas? – Are you sitting?
- Ĉu vi skribas? – Are you writing? Do you write?
Kiu?
This interrogative functions both as a pronoun ("who?") and as an adjective ("which?"), e.g.
- Kiu vi estas? – Who are you?
- Kiu instruisto sidas? – Which teacher is sitting?
The Suffix -ist
is used to form th ename of a person regularly engaged in some activity, e.g.
- instruisto – teacher
- hotelisto – hotelier, hotel-keeper
- esperantisto – Esperantist, adherent of Esperanto
The Suffix -in
is used to form the feminine of a noun:
- patro – father
- lernanto – pupil
- lernantino – pupil (female)
- instruisto – teacher
- instruistino – (woman) teacher
Affirmative Particle
jes has the same sound and meaning as the English "yes".
- Ĉu vi estas en la ĉambro?
- Jes, mi estas en la ĉambro.
Negative Particle
ne corresponds to "no" (opposite of "yes") and to "not":
- Ne, mi ne estas en la ĉambro.

'We thought we'd get one last Christmas': Mum who went to doctor with cough dies weeks after cancer diagnosis
Jane Brogan passed away suddenly at home on the day doctors were due to decide whether or not to continue treating her for the disease
by Katie DickinsonA much loved mum of three who went to the doctor's with a cough has died just six weeks after being diagnosed with lung cancer.
Jane Brogan passed away suddenly at home on the day doctors were due to decide whether or not to continue treating her for the disease.
The 38-year-old's world was shattered when what she thought was a chest infection turned out to be stage four lung cancer.
Jane, from Bedlington, had been suffering from a bad cough for about six weeks.
After attending hospital with what she thought was a minor ailment, she was horrified to be told she had months to live.
The single mum had started chemotherapy and was planning a final Christmas with her three children, Molly, 14, Elena, seven and Thomas, five, when she contracted pneumonia.
Doctors had said they wouldn’t be able to continue the cancer treatment while she had an infection, but told her that without it she wouldn’t live to see Christmas.
But on the day she was due to learn her fate, Jane died at her home in Northumberland .
“We’re devastated. We thought we’d get one last Christmas,” said Jane’s sister Julie.
“We’d even planned to move it forward after what the doctors said.
"She had texted me the night before saying she wasn’t feeling great and had been coughing a lot so was trying to get some sleep.
"From diagnosis to her passing away has only been six weeks.
"It’s really difficult- everyone’s struggling with it.
"Jane had been pretty upbeat through the whole lot, I don’t know how she’s been the way she’s been.
"She’d started buying the children Christmas presents."
Jane’s family and friends are continuing to fundraise to take her three children to Florida in May, with a charity evening at Bedlington Terriers FC planned for December 14.
A statement from her family said: “Jane was a much loved mam, daughter, sister, auntie and great auntie. She loved her friends, music, animals and, more recently, cakes.
"She was most devastated about leaving her children behind and missing out on them growing up, and key milestones in their lives.“
