grc65 is a part of cc65's GEOS support. The tool is necessary to generate required and optional resources. A required resource for every GEOS application is the header, that is: an icon, some strings, and some addresses. Optional resources might be menu definitions, other headers (e.g., for data files of an app.), dialog definitions, etc. Without an application's header, GEOS is unable to load and start it.
Currently, grc65 supports only menues and the required header definition, along with support for building applications with VLIR-structured overlays.
grc65 generates output in two formats: C header and ca65 source (.s). That is because the application header data must be in assembly format, while the menu definitions can be translated easily into C. The purpose of the C file is to include it as a header in only one project file. The assembly source should be processed by ca65 and linked to the application (read about the building process).
grc65 accepts the following options:
---------------------------------------------------------------------------
Usage: grc65 [options] file
Short options:
-V Print the version number
-h Help (this text)
-o name Name the C output file
-s name Name the asm output file
-t sys Set the target system
Long options:
--help Help (this text)
--target sys Set the target system
--version Print the version number
---------------------------------------------------------------------------
Default output names are made from input names with extensions replaced by
.h
and .s
.
A resource file has the name extension .grc
. That is not required, but
it will make for an easier recognition of the file's purpose. Also, cl65
recognizes those files. grc65's parser is very weak at the moment; so,
read the comments carefully, and write resources exactly as they are written
here. Look out for CAPS and small letters. Everything after a ';
'
until the end of the line is considered as a comment and ignored. See the
included
commented example .grc file for a
better view of the situation.
MENU menuName leftx,topy <ORIENTATION> {
"item name 1" <MENU_TYPE> pointer
...
"item name x" <MENU_TYPE> pointer
}
The definition starts with the keyword MENU
, then comes the menu's name,
which will be represented in C as const void
. Then are the co-ordinates
of the top left corner of the menu box. The position of the bottom right
corner is estimated, based on the length of item names and the menu's
orientation. It means that the menu box always will be as large as it should
be. Then, there's the orientation keyword; it can be either HORIZONTAL
or
VERTICAL
. Between {
and }
, there's the menu's
content. It consists of item definitions. First is an item name -- it has to
be in quotes. Next is a menu-type bit. It can be MENU_ACTION
or
SUB_MENU
; either of them can be combined with the DYN_SUB_MENU
bit
(see
the GEOSLib documentation for descriptions of
them). You can use C logical operators in expressions, but you have to do it
without spaces. So a dynamically created submenu will be something like:
"dynamic" SUB_MENU|DYN_SUB_MENU create_dynamic
The last part of the item definition is a pointer which can be any name that is
present in the C source code that includes the generated header. It can point
to a function or to another menu definition.
If you are doing sub(sub)menu definitions, remember to place the lowest level definition first, and the top-level menu as the last one. That way the C compiler won't complain about unknown names.
HEADER <GEOS_TYPE> "dosname" "classname" "version" {
author "Joe Schmoe"
info "This is my killer-app!"
date yy mm dd hh ss
dostype SEQ
mode any
structure SEQ
icon "sprite.raw"
}
The header definition describes the GEOS header sector which is unique to
each file. The definition starts with the keyword HEADER
, then goes the
GEOS file-type. You can use only APPLICATION
here at the moment. Then,
there are (each one in quotes) the DOS file-name (up to 16 characters), the GEOS
Class name (up to 12 characters), and the version info (up to 4 characters).
The version should be written as "V
x.y", where x is the
major, and y is the minor, version number. Those fields, along with both
braces, are required. The lines between braces are optional, and will be replaced
by default and current values. The keyword author
and its value in quotes name
the programmer, and can be up to 63 bytes long. info
(in the same format) can
have up to 95 characters. If the date
field is omitted, then the time of
that compilation will be placed into the header. Note that, if you do specify
the date, you have to write all 5 numbers. The dostype
can be SEQ
,
PRG
, or USR
. USR
is used by default; GEOS usually doesn't care.
The mode
can be any
, 40only
, 80only
, or c64only
; and,
it describes system requirements. any
will work on both 64-GEOS and
128-GEOS, in 40- and 80-column modes. 40only
will work on 128-GEOS in
40-column mode only. 80only
will work on only 128-GEOS in 80-column mode,
and c64only
will work on only 64-GEOS. The default value for
structure
is SEQ
(sequential). You can put VLIR
there, too; but
then, you also have to put in a third type of resource -- a memory definition.
The value of icon
is a quoted file-name. The first 63 bytes of this file
are expected to represent a standard monochrome VIC sprite. The file gets accessed
when the generated assembly source is being processed by ca65. Examples for
programs generating such files are Sprite Painter, SpritePad and the
sp65 sprite and bitmap utility. The default icon
is an empty frame internally represented in the generated assembly file.
MEMORY {
stacksize 0x0800
overlaysize 0x2000
overlaynums 0 1 2 4 5
}
The memory definition is unique to each file and describes several attributes related
to the memory layout. It consists of the keyword MEMORY
followed by braces which
contain optional lines. The value of stacksize
can be either decimal (e.g.
4096
) or hexadecimal with a 0x
prefix (e.g. 0x1000
). The default value
of 0x400 comes from the linker configuration file. The value of backbuffer
can be
either yes
or no
. The further means that the application uses the system-supplied
background screen buffer while the latter means that the program uses the memory of the
background screen buffer for own purposes. The default value of yes
comes from the
linker configuration file. If the structure
in the header definition is set to the
value VLIR
then it is possible and necessary to provide here the attributes of the
VLIR overlays. overlaysize
defines the maximal size for all VLIR records but number
0. It can be either decimal (e.g. 4096
) or hexadecimal with a 0x
prefix (e.g.
0x1000
). overlaynums
defines the VLIR record numbers used by the application.
Skipped numbers denote empty records. In the example, record number 3 is missing. Read
this description for details.
Before proceeding, please read the compiler, assembler, and linker documentation, and find the appropriate sections about building programs, in general.
GEOS support in cc65 is based on the Convert v2.5 format, well-known in the GEOS world. It means that each file built with the cc65 package has to be deconverted in GEOS, before it can be run. You can read a step-by-step description of that in the GEOS section of the cc65 Compiler Intro.
Each project consists of four parts, two are provided by cc65. Those parts are:
The application header is defined in the HEADER
section of the .grc
file and is processed into an assembly .s
file. You must assemble it, with
ca65, into the object .o
format.
Assume that there are three input files: "test.c
" (a C
source), "test.h
" (a header file), and
"testres.grc
" (with menu and header definitions). Note the
fact that I don't recommend naming that file "test.grc
"
because you will have to be very careful with names (grc65 will make
"test.s
" and "test.h
" out of
"test.grc
" by default; and you don't want that because
"test.s
" is compiled from "test.c
", and
"test.h
" is something completely different)!
One important thing -- the top of "test.c
" looks like:
#include <geos.h>
#include "testres.h"
There are no other includes.
This is a simple one step process:
cl65 -t geos-cbm -O -o test.cvt testres.grc test.c
Always place the .grc
file as first input file on the command-line in order
to make sure that the generated .h
file is available when it is needed for
inclusion by a .c
file.
grc65 -t geos-cbm testres.grc
will produce two output files: "testres.h
" and
"testres.s
".
Note that "testres.h
" is included at the top of
"test.c
". So, resource compiling must be the first step.
ca65 -t geos-cbm testres.s
And, voilá -- "testres.o
" is ready.
cc65 -t geos-cbm -O test.c
ca65 -t geos-cbm test.s
That way, you have a "test.o
" object file which
contains all of the executable code.
ld65 -t geos-cbm -o test.cvt testres.o test.o geos-cbm.lib
The last file is the GEOS system library.
The resulting file "test.cvt
" is an executable that's
contained in the well-known GEOS Convert format. Note that its name
(test.cvt
) isn't important; the real name, after deconverting, is the DOS name
that was given in the header definition.
At each step, a -t geos-cbm
was present on the command-line. That switch is
required for the correct process of GEOS sequential application building.
Large GEOS applications typically don't fit in one piece in their designated memory area. They are therefore split into overlays which are loaded into memory on demand. The individual overlays are stored as records of a VLIR (Variable Length Index Record) file. When GEOS starts a VLIR overlay appliation it loads record number 0 which is supposed to contain the main program. The record numbers starting with 1 are to be used for the actual overlays.
In "cc65/samples/geos
" there's a VLIR overlay demo application consisting
of the files "overlay-demo.c
" and "overlay-demores.grc
".
This is a simple one step process:
cl65 -t geos-cbm -O -o overlay-demo.cvt -m overlay-demo.map overlay-demores.grc overlay-demo.c
Always place the .grc
file as first input file on the command-line in order
to make sure that the generated .h
file is available when it is needed for
inclusion by a .c
file.
You will almost certainly want to generate a map file that shows (beside a lot of other infos) how large your individual overlays are. This info is necessary to tune the distribution of code into the overlays and to optimize the memory area reserved for the overlays.
grc65 -t geos-cbm overlay-demores.grc
ca65 -t geos-cbm overlay-demores.s
cc65 -t geos-cbm -O overlay-demo.c
ca65 -t geos-cbm overlay-demo.s
ld65 -t geos-cbm -o overlay-demo.cvt -m overlay-demo.map overlay-demores.o overlay-demo.o geos-cbm.lib
This is the first release of grc65, and it contains bugs, for sure! I
am aware of them; I know that the parser is weak, and if you don't follow the
grammar rules strictly, then everything will crash. However, if you find an
interesting bug, mail me. :-) Mail me also for help with writing your
.grc
file correctly if you have problems with it. I would appreciate
comments also, and help on this file because I am sure that it can be written
better.
grc65 is covered by the same license as the whole cc65 package, so you should see its documentation for more info. Anyway, if you like it, and want to encourage me to work more on it, send me a postcard with a sight of your neighbourhood, city, region, etc. Or, just e-mail me with info that you actually used it. See the GEOSLib documentation for addresses.
; Note that MENU can define both menues and submenues.
; If you want to use any C operators (such as "|", "&", etc.), do it WITHOUT
; any spaces between the arguments (the parser is simple and weak).
MENU subMenu1 15,0 VERTICAL
; This is a vertical menu, placed at (15,0).
{
; There are three items, all of them will call functions.
; The first and third ones are normal functions, see GEOSLib documentation for
; information about what the second function should return (it's a dynamic one).
"subitem1" MENU_ACTION smenu1
"subitem2" MENU_ACTION|DYN_SUB_MENU smenu2
"subitem3" MENU_ACTION smenu3
}
;; Format: MENU "name" left,top ALIGN { "itemname" TYPE pointer ... }
MENU mainMenu 0,0 HORIZONTAL
; Here, we have our main menu, placed at (0,0), and it is a horizontal menu.
; Because it is a top-level menu, you would register it in your C source by

{
; There are two items -- a submenu and an action.
; This calls a submenu named subMenu1 (see previous definition).

Book chapter abstract
Research on public space behavior often involves primary data collection including observations, surveys, and interviews. These methods can be costly and time consuming as well as divorced from the way people behave in physical space. We define big data as enormous streams of images, geographical coordinates, videos, and audio recordings that are usually generated in real time by sensors. Big data has the potential to support public space research.
The chapter discusses several challenges in public space research that may be addressed
by using big data approaches, including:
1) limited objectivity,
2) high cost in labor and time,
3) restricted scope (in geography and scale), and
4) lack of temporal fluidity and disassociation of behavior from precise geographical location.
Each challenge is discussed in the context of specific big data techniques that may help to overcome this limitation.
We present specific examples from existing big data research on public spaces, to demonstrate
the pros and cons of big data methods.
We discuss some of the challenges for big data research on public spaces, which include questions of privacy and the need for fairness, inclusivity, and quality control. Conclusions offer recommendations for the use of big data to inform public space design and planning. These include the use of web interface tools to enhance community engagement by crowdsourcing residents’ perceptions and experiences. Additionally, accurate measurements and large-scale analysis can support more equitable allocation of public spaces across neighborhoods and communities.
The chapter is in its final stages of editing and is planned to be published in the summer of 2019. We have been accepted to present the chapter in two urban design conferences in New Jersey and Greece in June 2019.

HTML5 & CSS3
Layout
Trainer: Kristina Spasevska /<EMAIL_ADDRESS>Assistant: Natasha Paneva /<EMAIL_ADDRESS>© 2020/2021 Seavus Education & Development Center
Lesson Overview
- Grouping elements in a block
- HTML5 layout elements
- Non-Semantic Elements
Introduction
- Webpages can and will look pretty different from one another, but they all tend to share similar standard components
- In addition to defining individual parts of your page (such as "a paragraph" or "an image"), HTML5 also boasts a number of
block level elements used to define areas of your website (such as "the header", "the navigation menu", "the main content column")
Introduction (2)
- In your HTML code, you can mark up sections of content based on their functionality — you can use elements
that represent the sections of content described above unambiguously, and assistive technologies like screenreaders
can recognise those elements and help with tasks like "find the main navigation", or "find the main content."
- To implement such semantic mark up, HTML5 provides dedicated tags that you can use to represent such sections
Headers & Footers
-  represents a group of introductory content. If it is a child of  it defines the global header of a webpage,
but if it's a child of an
 or
 it defines a specific header for that section
-  represents a group of end content for a page that generally contains fine print, copyright notices, contact info
or secondary navigation

Page main heading

 2020 © SEDC. All rights Reserved.

Navigation
- The  contains the main navigation functionality for the page.
Secondary links, etc., would not go in the navigation
- Links to the site's main sections; usually represented by menu buttons, links, or tabs
- Many web designers consider the navigation bar to be part of the header rather than an individual component, but that's not a requirement

Main Content
- The  is for content unique to this page.
Use  only once per page, and put it directly inside .
- Ideally this shouldn't be nested within other elements

Articles
- The
 element encloses a block of related content that makes sense
on its own without the rest of the page (e.g., a single blog post)
Sections
- The
 element is similar to
, but it is more for grouping together a single part of the page that constitutes one single piece of functionality
(e.g., a mini map, or a set of article headlines and summaries), or a theme
- It's considered best practice to begin each section with a heading
- Also note that you can break
s up into different
s, or
s up into different
s, depending on the context

Aside
- The  element contains content that is not directly related to the main content but can provide additional
information indirectly related to it (glossary entries, author biography, related links, etc.)
- Usually, it's contextual to what is contained in the main content
- The  content can also be nested within the main content

Non-semantic wrappers
- Sometimes you'll come across a situation where you can't find an ideal semantic element to group some items
together or wrap some content
- For cases like these, HTML provides the

and  elements
Non-semantic wrappers (2)
-
 is a block level non-semantic element, which you should only use if you can't
think of a better semantic block element to use, or don't want to add any specific meaning
- As a "pure" container, the
 element does not inherently represent anything
-  is an inline non-semantic element, which you should only use if you can't
think of a better semantic text element to wrap your content, or don't want to add any specific meaning

Ch 2: Treatment


Table of Contents:
To be written: but there are seriously a lot of written material on the 'NET about mysql, this guide is for how to install the package in OpenBSD and some basic testing tools to verify everything is running.
Another great location for aids is http://www.sancho2k.net/filemgmt_data/files/mysql_notes.html
[ref: Paul Dubois, MySQL, (Indiana, New Riders, 2000)]
Reference: mysql-server-4.0.18.tgz (port-package) OpenBSD 3.5Beta
Install the mysql package using pkg_add. The package installation will install the mysql binaries and create the default database by executing mysql_install_db. This includes initialising the data directory (--datadir=/var/mysql,) and Grant Tables for the 'root' user. The datadir is where the system-wide databases will be located. The Grant Tables is specify access privileges available. Together with creating the database directories/files the package will also chown/chmod the directories. Install the package with the standard method shown below:
| # pkg_add /[path-to-package]/mysql-server-4.0.18.tgz |
The package automatically creates the user '_mysql' (on my system with uid 502) and group '_mysql' (gid 502) which are used for running the sql server.
Somewhere in the life of mysql development, the libraries were moved from /usr/local/lib to their own directory /usr/local/lib/mysql. Because of this, we need to specify its location for the machine startup routines. We make these changes in rc.conf.local by modifying the reference to shlib_dirs:
Edit rc.conf.local and add the following line in Section 3:
| shlib_dirs="$shlib_dirs /usr/local/lib/mysql" # extra directories for ldconfig |
This will include the library directory to the original settings in rc.conf which is usually:
| shlib_dirs= # extra directories for ldconfig |
Priority 1: Set the root access password for the database, and before we can do that we need to temporarily start mysql.
| # /usr/local/bin/mysqld_safe & # /usr/local/bin/mysqladmin -u root password mypassword |
If you already have accounts/users on the system then a more secure way of changing the password is to log into the mysql client program and create the password from in there.
For example, after 'mysqld_safe &' do something like the below. (courtesy of http://www.revunix.tk/)
| # /usr/local/bin/mysqld_safe & # /usr/local/bin/mysql -u root |
| Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 to server version: 4.0.20-log Type 'help;' or '\h' for help. Type '\c' to clear the buffer. |
| mysql> SET PASSWORD FOR root@localhost=PASSWORD('new_password'); |
| Query OK, 0 rows affected (0.07 sec) |
Reference: fstat(1)
Verify the server is running by using the 'fstat' in the following example:
| # fstat | grep "*:" | grep mysql |
| _mysql mysqld 22190 5* internet stream tcp 0xd0bc25a4 *:3306 |
Now we know through fstat that the mysql daemon (mysqld) is running with user privileges of _mysql and listening on port 3306. The [ | grep "*:" ] filters for processes that have an "internet stream" open. The [ | grep mysql ] further filters down to processes with the word mysql on the line.
One neat feature of the 'fstat' program is that the "*.nnnnn" indicates the port on which the processes is listening.
The displayed line is fstat(1):
| USER Command PID FD DOMAIN Socket_Type Socket_Flag Protocol_Numb:Protocol_Address |
| _mysql mysqld 22190 5* internet stream tcp 0xd0bc25a4 *:3306 |
Our first test for validating the installation is to access the MySQL database server and look at the server maintenance database 'mysql.' We log in to the system through mysql interactive interface to the server.
| # /usr/local/bin/mysql -u root -p |
| Enter password: mypassword <--
this will show as ********** Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 5 to server version: 4.0.18 Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> |
The mysql> prompt allows sql statements and MySQL commands to be entered. Most commands are completed by using the ";" semi-colon delimiter.
We check whether the initial database creation was successful (mysql, and test.) Use the show databases; command. The MySQL package should have successful created the system database 'mysql' and a sample database 'test'.
| mysql> show databases; |
| +----------+ | Database | +----------+ | mysql | | test | +----------+ |
We can check whether the mysql database has been installed by looking at the installed tables which should look like the below.
| mysql> use mysql; mysql> show tables; |
| +-----------------+ | Tables in mysql | +-----------------+ | columns_priv | | db | | func | | host | | tables_priv | | user | +-----------------+ |
The user table is the system wide table to record what users are allowed onto the system and with what privileges. By using the 'describe' command we can see a list of the table fields and data-types. In this table it shows us the different levels of privileges available on the MySQL server.
| mysql> describe user; |
| +-----------------+---------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------------+---------------+------+-----+---------+-------+ | Host | char(60) | | PRI | | | | User | char(16) | | PRI | | | | Password | char(16) | | | | | | Select_priv | enum('N','Y') | | | N | | | Insert_priv | enum('N','Y') | | | N | | | Update_priv | enum('N','Y') | | | N | | | Delete_priv | enum('N','Y') | | | N | | | Create_priv | enum('N','Y') | | | N | | | Drop_priv | enum('N','Y') | | | N | | | Reload_priv | enum('N','Y') | | | N | | | Shutdown_priv | enum('N','Y') | | | N | | | Process_priv | enum('N','Y') | | | N | | | File_priv | enum('N','Y') | | | N | | | Grant_priv | enum('N','Y') | | | N | | | References_priv | enum('N','Y') | | | N | | | Index_priv | enum('N','Y') | | | N | | | Alter_priv | enum('N','Y') | | | N | | +-----------------+---------------+------+-----+---------+-------+ |
Grabbing a set of information from the user table lets us see who has been given access to the system. The machine I have mysql installed on is called iwill, and you should see a similar result to the select query on your machine. Note the "blank" users is used by mysql for 'anonymous' and at the beginning only --user=root has privileges to do anything on the system. Note that the password field is encrypted with a one-way encryption system similar to but not the unix crypt() function.
| mysql> select host, user, select_priv, grant_priv, password from user; |
| +-----------+------+-------------+------------+------------------+ | host | user | select_priv | grant_priv | password | +-----------+------+-------------+------------+------------------+ | localhost | root | Y | Y | 162eebfb6477e5d3 | | iwill | root | Y | Y | | | localhost | | N | N | | | iwill | | N | N | | +-----------+------+-------------+------------+------------------+ |
| mysql> quit |
To configure OpenBSD to automatically start mysql with every system start-up then you can edit the rc.conf.local file to modfiy the configuration and rc.local to take action when the configurations are set.
Edit: /etc/rc.conf.local file to include in Section 2 the following lines:
| mysql=YES |
Edit: /etc/rc.local
After the 'starting local daemons' and before the following echo '.', Insert the following instructions to the /etc/rc.local file:
| echo -n 'starting local daemons:'
# [ ... stuff left out ... ] |
| if [ X"${mysql}" == X"YES" -a
-x /usr/local/bin/mysqld_safe ]; then echo -n " mysqld"; /usr/local/bin/mysqld_safe --user=_mysql --log --open-files-limit=256 & for i in 1 2 3 4 5 6; do if [ -S /var/run/mysql/mysql.sock ]; then break else sleep 1 echo -n "." fi done # # Apache chroot Settings mkdir -p /var/www/var/run/mysql ln -f /var/run/mysql/mysql.sock /var/www/var/run/mysql/mysql.sock # # Postfix chroot Settings if [ "X${postfix_flags}" != X"NO" ]; then mkdir -p /var/spool/postfix/var/run/mysql ln -f /var/run/mysql/mysql.sock /var/spool/postfix/var/run/mysql/mysql.sock fi fi |
| # [ ... stuff left out ... ] echo '.' |
Now each restart of the machine will automatically check to see whether we have enabled mysql in the configuration file (rc.conf) and then start the mysql daemon. If we wish to disable mysql we can simply change mysql=YES to mysql=NO
Once you have the startup script working you can get rid of all the extraneous messages that mysql startup daemons makes by changing the mysqld_safe line to be something like the following:
| /usr/local/bin/mysqld_safe --user=_mysql --log --open-files-limit=256 > /dev/null 3>&1 2>&1 & |
Note: /usr/local/share/mysql/mysql.server is a script for starting/stopping mysql daemon. The files are there with mysql-server-4.0.18 on OpenBSD 3.5 so your mileage may vary.
To stop the MySQL server, a standard approach is to use the mysqladmin program as shown below:
# /usr/local/bin/mysqladmin shutdown
Of course you have to be logged in as a user with privileges to shutdown the server (as noted above in the the user table, field Shutdown_priv. Otherwise if you had root access you could shutdown the server through a 'kill'.
Security Notice: MySQL installs anonymous login access from the localhost with its default installation, you may or may not consider this a security issue. If you do consider it a problem then you can remove the anonymous access by using commands similar to that shown below:
| # /usr/local/bin/mysql -u root -p |
| Enter password: mypassword <--
this will show as ********** Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 6 to server version: 3.22.32 Type 'help' for help. |
| mysql > use mysql |
| Reading table information for completion
of table and column names You can turn off this feature to get a quicker startup with -A |
| mysql > delete from user where user = ""; |
| Query OK, 2 rows affected (0.08 sec) |
mysql will search for user configurations in a file called ~/.my.cnf which has a simple format to let you specify settings we have been forced to manually type with each invocation (start) of msyql.
~/.my.cnf have the below settings which are user configurable.
| [client] host= user= password= socket= [mysqld] socket= |
In Unix, the mysql command line supports using a screen editor for modifying and creating queries. The 'edit' command in the MySQL command line calss the text editor of your choice (typically set with the EDITOR environment variable, probably vi on your OpenBSD.)
mysql> edit
If you make a mistake in keying in a command, then you can use the up-arrow to review your command, or you can type in edit to re-enter. edit remembers the previous command string you typed, so it is especially useful getting those large queries working.
[ref<EMAIL_ADDRESS>October 2001 archives]
[ref: /usr/ports/databases/mysql/patches/]
One problem that seems to be reported a lot on the mailing lists (and subsequently responded to) is that mysql at a large level of use begins to consume all available resources and locks up the system.
The answer for this problem OpenBSD 2.x and OpenBSD 3.0 have been well documented at http://www.hostbaby.com/misc/mysql-openbsd.html by Derek Sivers.

Manual
Beginning users should take a look at the
Getting started guide for a tutorial on
running TopHat-Fusion.
How to use fusion mapping
After running tophat, you can run tophat-fusion-post to filter out fusion candidates.
Usage: tophat-fusion-post [options]* <index_base>
|
Options:
|
|
|
-v/--version
|
Prints the help message and exits.
|
|
-p/--num-threads
|
The number of threads used. The default is 1.
|
|
--num-fusion-reads
|
Fusions with at least this many supporting reads will be reported.
The default is 3.
|
|
--num-fusion-pairs
|
Fusions with at least this many supporting pairs will be reported.
The default is 2.
|
|
--num-fusion-both
|
The sum of supporting reads and pairs is at least this number for a fusion to be reported.
The default is 0.
|
|
--max-num-fusions
|
The maximum number of reported fusions.
The default is 500.
|
|
--fusion-read-mismatches
|
Reads support fusions if they map across fusion with at most this many mismatches.
The default is 2.
|
|
--fusion-multireads
|
Reads that map to more than this many places will be ignored.
The default is 2.
|
|
--non-human
|
If your annotation is different from that of human, use the option.
|
|
--fusion-pair-dist
|
Pairs with this specified distance are counted as supporting evidence for the fusion. The default threshold for the inner distance is 250.
|
Additional Output
In addition to those files ouput by TopHat,
the tophat (with --fusion-search) and tophat-fusion-post scripts produce a number of files in the directories
in which they were invoked. Most of these files are internal, intermediate
files that are generated for use within the pipeline. The output
files you will likely want to look at are:
tophat (with --fusion-search option)
- accepted_hits.bam.
A list of read alignments in SAM format. SAM is a
compact short read alignment format that is increasingly being
adopted. The formal specification is here.
We assume that a fusion alignment involves two chromosomes or different places on the same chromosome (distant or inversion).
So, a fusion alignment is reported in two partial alignments (one before the fusion point and the other after) as follows:
(1) SRR064286.11667197 chr12<PHONE_NUMBER> 16M chr20 625050470 ATATGTTTGAGAGGCT BCBCCBCCCBBBBBBB XF:Z:1 chr12-chr20 2910488 16M62500758F34M
(2) SRR064286.11667197 chr20<PHONE_NUMBER>5 34M = 625050470 GGCTGAGGAGGAGGAGCTCAGGGCTGAGCTTACC BB?B@;@B?AA?A?;?:@>>@@B>>;;B>?=9## XF:Z:2 chr12-chr20 2910488 16M62500758F34M
Some of fields are skipped for the sake of illustration, as shown above,
16bp of 50bp read is mapped on chr12 and 34bp is mapped on chr20.
The whole fusion alignment is available in a custom field XF in both partial alignments above.
XF:Z:1 and XF:Z:2 indicates the first and the second partial alignments, respectively.
A new CIGAR operator 'F' (Fusion) is introduced to indicate the presence of a fusion in read alignments.
The following example shows a read alignment across a fusion between chromosome 20 and chromosome 12.
XF:Z:1 chr12-chr20 2910488 16M62500758F34M
The left most base of a read (SRR064286.11667197) is mapped to 2910488th base of chromosome 12
from which the first 16 bases of a read are mapped from 2910488 to 2910503 on chromosome 12,
the 17th base of the read is mapped to 62500758th base of chromosome 20, and
the remaining 34 bases are mapped from 62500758 to 62500791 on chromosome 20.
The precise fusion point is between 2910503 on chromsome 12 and 62500758 on chromosome 20.
Note that small letters such as m, n, i, d have opposite interpretations of big letters,
meaning a coordinate is decreasing instead of increasing.
In case the other end spans a fusion point, a custom field XP used as follows:
SRR064286.73586371 chr11 44890 50M XP:Z:chr1-chr10 14482
The read (SRR064286.73586371) is mapped on chr11 at 44890th position
while its mate partner spans a fusion point between chr1 and chr10.
- fusions.out.
A list of fusions tophat (with --fusion-search) finds before running tophat-fusion-post, where each fusion is supported by at least one read alignment.
Each row represents a fusion with the detailed description given in the below.
A row can be split into seven rows using @ as a line separator.
chr20-chr17 49411707 59445685 ff 106 116 167 0 37 36 0.569598 @

-6:1 11:0 16:-3 18:1 14:6 14:6 15:7 23:0 5:21 31:5 18:19 36:-1 ...
This is a fusion between 49411707th base on chromosome 20 and 59445685th base on chromosome 17.
ff is the orientations of the two chromosomes - both chromosomes are in forwarding direction, like (chr 20) -----> -----> (chr 17).
106 is the number of reads that span the fusion, 116 is the number of mate pairs that support the fusion,
167 is the number of mate pairs that support the fusion and whose one end spans the fusion.
0 is the number of reads that contradict the fusion by mapping to only one of the chromosomes 20 and 17.
37 and 36 are the number of bases on the left and right sides of a fusion, respectively, covered by spanning reads.
The second row is likely to be dropped in the next version.
The third row shows two 50-bp contigs around a fusion point on chromosome 20.
The fourth row is similarly defined for chromosome 17.
The fifth row is depth coverage by spanning reads on chromosome 20 from 49411707th base to 49411658th base.
The sixth row is depth coverage by spanning reads on chromosome 17 from 59445685th base to 59445734th base.
The seventh row is distances (distance1:distance2) between a mate pair and the fusion,
i.e., distance1 bewtween the left end of a pair and the left side of the fusion and
distance2 between the right end of a pair and the right side of the fusion.
A useful linux command 'awk' can be used for filtering fusions as follows:
awk '{if($5 > 100) print}' fusions.out | sed 's/@\t/\n/g'
Here, $5 is the number of spanning reads, this command shows the fusions supported by at least 100 spanning reads.

Sri Lanka prisoners demand freedom after Swede’s killer pardoned
COLOMBO, Nov 12 — Hundreds of inmates at Sri Lanka’s biggest high-security prison staged a second day of protests today, demanding their freedom after the president pardoned a well-connected man convicted of brutally murdering a Swedish teenager.
Jude Jayamaha, convicted of killing Yvonne Jonsson in Colombo in 2005, walked free on Saturday following the highly unusual pardon granted by President Maithripala Sirisena, whose term in office ends this weekend.
Police said around 1,000 prisoners had refused yesterday to return to their cells at Welikada prison in Colombo, while four inmates had clambered onto the prison’s roof.
An official said police commandos were standing by outside with orders to move in if necessary.
There were reports of a similar protest at another prison in the south of the island.
The prisoners are demanding their release on the same terms as Jayamaha, who hails from a wealthy Colombo family with political connections.
The victim Jonsson, 19, whose mother was Sri Lankan and father Swedish, was holidaying in Sri Lanka when she was beaten to death in a Colombo high-rise apartment after she and Jayamaha had an argument.
The trial heard her skull had been fractured into 64 pieces.
Sirisena announced the pardon last weekend ahead of Saturday’s presidential election, when he is leaving office.
The announcement of the amnesty provoked an angry backlash on social media as well as from mainstream political parties.
The ruling party presidential candidate, Sajith Premadasa, said if elected he would consider legal options to overturn Sirisena’s pardon.
“I condemn the action of granting this amnesty,” Premadasa told reporters in Colombo today. “We will examine all legal aspects.”
He added: “The release of a murderer does not conform to my set of ethics.”
Jayamaha was initially sentenced to 12 years in prison. He appealed to a higher court, which rejected his plea and instead sentenced him to death, which was reaffirmed by the Supreme Court in 2014.
Jonsson’s sister Caroline wrote in a Facebook post about her concerns over Jayamaha’s pardon before the amnesty announcement.
“He showed and continues to show absolutely no remorse for what he has done,” she wrote. — AFP


I am a PhD Candidate in Aerospace Engineering Sciences, working for Dr. Steve Nerem. My research focuses on time-variable Earth gravity, using GRACE science data to studying hydrologic and cryospheric surface mass changes. These changes are indicative of groundwater storage changes (for example, due to drought or flooding) and glacial ice-mass loss due to melting, and are major indicators of global climate change.
More specifically, my research utilizes surface mass concentrations (or "mascons") to represent the gravity field and extract useful information about surface mass variations on global, regional, and local scales. A more detailed description can be found by selecting the "Research" tab in the navigation bar.
Please feel free to look over my page, and contact me if you would like to know more about my research.

Cartesian Interactive Data Display (CIDD)
User Manual
National Center for Atmospheric Research
P. O. Box 3000
Boulder, Colorado 80307-3000

Part I: Using CIDD
1.0 Introduction to CIDD
CIDD software was developed for displaying real-time gridded data in National Center for Atmospheric Research (NCAR) field research projects. This program has been used for forecasting experiments for thunderstorms, hail, and icing; aviation weather product verification; and coordination of research aircraft and vehicles. It has been used for displaying real-time data from radars, models, surface analysis, satellite imagery, and tracking algorithms.
CIDD's display capabilities include PPI/plan views, RHI/cross sections, and CAPPI (see Section 3.2). Both RHI scans and reconstructed RHI from volume scans can be displayed.
In addition to real-time display, the software provides archival data access and movie looping capability. It also provides extensive overlay display capabilities, including geographic maps (state and county borders, roads, terrain), wind vector sets, icons (radars, PAM stations, airports, airplanes, vehicles), and real-time weather alerts or symbolic products (gust fronts, station plots, microbursts, storm tracking, precipitation, weather forecasting).
CIDD provides a simple graphic editing tool, allowing the user to draw features over the data display and export them on a network for analysis and forecasting.
An arbitrary number of fields can be accessed and the user can quickly switch between the displayed fields. The user can zoom in to preset domains in an arbitrary sub-area in both real-time and movie displays (see Section 6.0).
Other features include:
· Ability to layer multiple grids together onto each image.
· Modular, distributed design client-server for accessing data.
· Flexible interface design allows CIDD to be easily adapted to different project needs and weather product environment.
· CIDD allows point and click reading of field values and locations.
· CIDD can be set up to operate in a simplified, pre-configured mode for non-meteorologist use.
· CIDD provides a shared-memory interface to auxillary programs, allowing specialized applications to be integrated with the main display.
· CIDD has a highly configurable design. It can be set up to behave primarily as a real-time display or as an archival data analysis display.
· The display can gather and integrate data from geographically distant sights via internet connections.
CIDD is an X-windows-based display requiring a local X-server supporting at least 256 colors.
Radar operators can use CIDD for monitoring radar operations and product generation. Research meteorologists can use CIDD for examining real-time or archived radar data, weather product validation, coordinating field airplanes and vehicles, and forecast experiments.
Operational meteorologists can use CIDD for weather monitoring, operational forecasting, situation display, and product verification. End-users can use CIDD to display pre-configured weather-related products.
The CIDD User Manual explains how to use, install, and customize CIDD. Part I of the User Manual gives instructions for anyone who intends to use CIDD. The program has many features and not all of them will be apparent without reading Part I of the manual.
Part I of the manual starts with a brief review of mouse functions. It assumes that the user has some experience using a mouse. The next section explains the functions accessible from the Main Control panel of CIDD and the pop-up panels.
The following chapters explain all functions of the program in detail. Part I is the only part of the manual that the typical CIDD user needs to read.
Part II of the User Manual explains how to install and set up the program. Only people who install the program or want to add new data sources need to read this part of the manual.
The Installation Section consists of steps that an experienced Unix user can perform and one step, Writing a Server, requires C programming experience.
Part III of the User Manual consists of appendices that describe each of the parameters used to customize CIDD. Customization involves modifying text configuration files.
2.0 Getting Started
This section briefly reviews mouse actions for working with an X-window application. It is assumed that the user is familiar with the X-window system, so does not go into great detail.
If the user is instructed to click on a selection, s/he positions the pointer over the selection and presses and releases the left button on the mouse. The left button is used for most actions; if the user needs to press a different button, the instructions will indicate which button is needed.
The main CIDD window's size and position on the screen is controlled through standard X-window manager controls. See your window manager documentation.
If the user is instructed to drag an object, move the pointer over the object, press the button when the mouse is positioned over the object, continue to hold the button while moving the object and release the button when the object is correctly positioned.
If instructions indicate that a left click is needed, position the mouse and then press and release the left mouse button.
In review:
LEFT = select - use to select buttons, text, zoom or report data values
MID = move/adjust - moves image display area
RIGHT = menu or select a vertical cross section
Select Quit from the window manager controls.
The main CIDD screen consists of two regions. Along the top is a control panel which controls movie looping and the display of the auxillary control panels. Below is the imaging area for data. Another region is the thin border line around the display. Clicking the right mouse button on this border displays the window's menu; this feature is window manager dependent, however. The menu offers the choice of closing the CIDD window (it becomes an icon) or quitting from the program (also window manager dependent).
2.2.1 An example of the CIDD full screen display window.
The Main Control Panel contains buttons to control what is displayed. The first of these is the loop button. A window containing information about the radar, such as altitude, beam width, longitude, and latitude appears in the display area.
The radar button is a toggle, meaning that by clicking once, the Radar Data window appears and clicking a second time makes the window disappear.
The next group of choices is the data field selections, i.e., reflectivity, velocity, and signal-to-noise ratio. The number of fields that can be displayed is customizable and dependent on the capabilities of the radar. To select one of the fields, move the mouse so the pointer is over the button and left click the mouse. This action de-selects whatever other field had previously selected.
As a shortcut, keep the pointer in the display area and click the middle mouse button. This action toggles back and forth between the two most recently selected fields.
The next button of the control panel is the Vertical display button. RHI gives a vertical cross section display along an arbitrary line.
2.3.3 Example, vertical cross section display window.
A display with range on the horizontal axis and height on the vertical axis is placed on the screen. Fields are selected independently from the plan view window, using the menu (right) button. To remove the display, left click the vertical button a second time. Details about using the control window can be found in ``Using Vertical Cross Section'' in this manual (see Section 5.0).
CIDD is capable of displaying constant altitude PPI and surface and satellite imagery. CIDD shows the data in its native state. In order to determine the type of plan view needed, look at the units next to the height slider.
CIDD has preset zooms. The user can click and drag on ``custom'' zoom preset by using the left button. Unzoom by picking one of the predefined domains.
2.3.6 Example, defining the area to zoom.
CIDD will preserve its aspect ratio by adjusting the zoom area to fit the window.
The next control in the Main Control Panel is a slider for adjusting the brightness of the displayed radar data. To use the slider, drag the slider by holding down the left mouse button. To dim the display, move the slider to the left. The primary purpose of dimming the display is to make overlays more easily visible.
Clicking the Overlay button creates a window which displays various overlay choices to be placed over the radar display area. The overlays may include roads, other maps, grids, or weather products. At the left of the window are categories of overlay and at the right are specific overlays. See Section 4.0, ``Using `PRDS' Product Selection'' for more information on this feature.
Clicking the Draw button on the Main Control panel displays options for drawing. See Section 7.0, ``Using Draw'' for more information on this feature.
The last button on the Main Control panel is the on-line help button. Clicking this button (using the left mouse button) displays a window containing basic instructions from this manual. A slider bar at the left of the window lets you scroll quickly through the information to find answers to your questions. To move quickly to a particular point, drag the slider up or down using the mouse. To move backward or forward one page at a time, click on the bar either above or below the slider.
An additional feature of the main display area and the cross section display is the ability to obtain numeric values for a point. To do this, move the mouse so that the pointer points to the location for the reading desired. Click the left button on the mouse. A readout of numerical values appears on the top of the display area. The readout includes the latitude and longitude data value for the field (reflectivity, velocity, etc.) being displayed. This data is written to its shared memory area for auxillary programs to use. For example, a satellite image registration tool was built using this interface.
3.0 Using Zoom
4.0 Using ``PRDS'' (Product Selection)
To use overlays, click on the Overlay button in the Main Control panel. A menu window will pop up displaying the symbolic product (alerts) selections.
4.1. Example of overlay menu window.
The menu window contains three separate lists. The list at the far left is a listing of overlay classes. Some examples of classes include maps, microburst products, and tornado products. Each of these may contain a number of objects. The objects in a class are listed in the middle list. Examples of objects in the Map class are a road map, a county map, or a rectangular grid. Objects in a product class have a different naming convention, e.g., they have a short text name followed by the time that the product originated.
Objects may have a further subdivision in the third list. For weather products, the third list may have a time sequence tracking a particular prediction. For example, if the class is microburst products, and the object is a particular microburst prediction, the third list may have a time sequence tracking the microburst. The third list is also used more generally for providing a third level of subdivision.
Objects often have no third level list. For example, a county map in the class Maps would not usually have any subdivision in the third list.
To use the overlay menu, first choose a class of overlays from the left list. Items in the left list have a face symbol to the left, a name in the center, and end with a number. A smiling face symbol indicates that overlays in that class are available, and a frown indicates that overlays in that class are not available (the product source has been turned off). The number indicates how many objects are available in that class. To select a class, click at the left of the overlay name, near the face symbol. To obtain a sublist of objects in the class, click at the right side of the class name, over the number, using the mouse button.
To choose an object, use the same procedure. Click at the left side of the object name for object selection. To view a sublist for the object, click near the right side of the name.
To choose an item within an object, obtain the list of items by clicking at the right of the object name. Select the item or items by clicking on the names of the items.
An object must be selected (the object name is highlighted) for all 2 or 3 levels before the object will be displayed over the radar data area as an overlay. CIDD can support as many overlays, simultaneously, as the user wishes to use.
By clicking on the Cut button, objects or subitems of objects (but not classes) can be removed easily. The pointer changes shape and any object or subitem clicked on will permanently be removed from the database. There is no way to restore an object once it has been cut.
The Loop button is currently not a supported function.
CIDD can be run without overlay capability if desired. The overlay function is a separate process called ``prds'' that is independent of CIDD. The functioning of the overlay program is controlled by a file called ``prds.conf''. Whether or not prds will be active depends upon whether it is included in the cidd script file. CIDD also works with prod_sel.
(description here)
The Overlay Panel options are:
· Maps
· Range rings, azimuth lines
· Contours of selected fields
· Gridded fields - ``Layering'' with thresholding
· Display winds (vectors, barbs, etc.)
· Dim - gridded data to highlight overlays, products
· Control product look (line width, fonts, etc.)
· Save image feature
5.0 Using Vertical Cross Section
To obtain the cross section display, either click on the ``vert'' button or click and drag the right button over the plan view image.  The window contains a graph with the range on the X-axis and the height on the Y-axis.
5.1. Example of cross section display.
5.2. Selecting the Cross Section
Click and drag the right mouse button. Change fields by selecting a field in the menu with the right mouse button.
6.0 Movies
In real-time mode, CIDD automatically updates the imagery and movie loops.
To display data in Archive mode, click on the Movie button in the Main Control panel. A Movie Control panel appears on the screen. The image will move according to the times that are indicated for the Movie Frame Time Interval (minutes) and Number of Frames (per second).
6.1. The Movie Control panel.
By dragging the Speed slider to the left (slower) or right (faster) the user can change the speed at which data is displayed.
If Step is selected while in Time mode and the user clicks on the bar to the right of the Frame slider, the next frame at the specified tilt will be displayed. Clicking on the bar to the left of the Frame slider will jump back one frame in time. The A (All) and V (Volume) buttons also affect display of data in both Auto and Step. By Clicking on A, all frames at the specified elevation, including repeats of an elevation in a volume, are displayed. By clicking on V, only one frame per volume is displayed.
7.0 Using Draw - ``Expt''- The Exporter
CIDD supports a screen drawing capability. This capability can be used to draw weather products or other graphic overlays. CIDD is also capable of exporting the weather products drawn in CIDD to other programs. CIDD can also receive weather products from itself for addition to its product overlay database.
Knowledge of the drawing methods is not needed for learning other functions of CIDD. Since the use of the drawing function is for limited purposes, reading this section is optional.
To use the drawing capability, move the mouse so that the pointer is over the Draw button in the Main Control panel and left click the mouse. A pop-up menu is displayed in the data display area.
7.1.1 Example, of the Draw pop-up menu.
The pop-up menu has four buttons: New, Copy, Export, and Cut. The menu also has a list box which shows the names of drawings as they are created. When Draw is first selected, the box is empty (no drawings have been created yet). To start, click on New using the left mouse button. A second menu is displayed. This menu has choices for type of object. For example, in the diagram there are choices of Nowcast, Boundary, and Rotation among the six choices. On the menu there is also a set of choices for choosing the initial shape of an object. Choices for initial shape are a circle, a rectangle, a line, and a sym (symbol), and an unrelated choice of mdf (modify).
Click on one of the choices for object type. Then click on a choice for initial shape. Move the pointer into the radar data display area and click the right (not left) button. A shape appears near the pointer. Next to the shape is a square control box.
Each shape that is created has a square control box nearby. The square control box is composed of four small squares each holding a symbol. The four squares provide four different functions.
7.2.1 Example of an active drawing with its control box.
Note: To use these functions, and for other drawing tasks, use the right mouse button, not the left button as is done for most other actions. Continue to use the left button in the pop-up menus.
To move an object, move the pointer onto the upper left square in the control box. Press and hold the right mouse button and drag the control box, tied to the drawing, to its new location and release the mouse button.
To change the size of a drawing, use the square at the lower left of the control box, marked with a +/- symbol. Move the pointer onto this square, press the right mouse button, and drag the control box toward the drawing to decrease its size, or away from the drawing to increase its size. Release the mouse button when the drawing is the correct size.
Note: For a symbol, changing the size or location are the only changes possible. Changing the points or shape is not possible.
If a line is chosen as the initial shape, the user can add line segments by moving the pointer to new locations and clicking the right mouse button. If the user wants to terminate one set of line segments and start a new line, click on the square at the lower right of the control box, marked with an X. The next point clicked on will not be attached to the previous segments.
When drawing line segments, instead of clicking the mouse, press the mouse button and drag the point to its final location. By dragging the point close to the end point of another segment, the two end points will join and the line segments will form a closed shape.
Use the termination square, the upper right square of the control box, to terminate drawing. This action may automatically select Export, as if selected from the first pop-up menu. The configuration file for drawing, exprt.conf , determines whether termination automatically selects export. Using Export is explained further below.
For any shape except a symbol, move the pointer near to a point in the shape and press the right mouse button. This action grabs the point, splitting the line into two segments on each side of the point. It is possible to drag the point and attach line segments to a new location.
After creating a circle or rectangle, it is possible to modify these objects. Move the pointer into the data display area and press and hold the right button instead of clicking it. For a rectangle, drag the mouse near the marked corner and drag the corner to change the shape and size. For a circle, drag the mouse to change the size of the circle.
By selecting ``New'' several times you will have several separate drawings on the display. The drawings are listed in the pop-up menu. Only one drawing is active at any time. The active drawing has the control box located nearby. The active drawing is the only drawing that can be modified.
Drawings listed in the pop-up menu are identified by an abbreviation for the type of object followed by the data time. The data time is the time displayed for the data when the object is drawn.
By clicking on the left part of the drawing name in the list box, you make the drawing active. Clicking over the letter ``S'' at the right of the name toggles the drawing between being invisible and visible.
By selecting ``Cut'' from the pop-up menu, the active drawing is erased. There is no way to restore a drawing once it has been cut.
By selecting ``Copy'' from the pop-up menu, the secondary pop-up menu appears. There are two types of copy to choose from; one type copies only the name of the active drawing and the other type copies the shape but not the name.
To copy the shape, select the type of object from the secondary pop-up menu and from the same menu, select mdf (modify). The active shape is copied. The copy is difficult to see because it is placed on top of the original. To move the copy, move the pointer onto the upper left square of the control box and drag the copy to a new location.
To copy the name only, don't change the object type. Select an initial shape. Move the pointer into the data display area and click the right mouse button. A new shape appears with the name copied from the last active drawing.
To export a drawing from CIDD, select the Export button. The exported drawing can be imported for use in other programs or it can be imported back into CIDD to be added to the overlay database.
Selecting export causes a pop-up window for Export to be displayed. (If the configuration file specified that the type of object is not exportable, an error message is displayed.) The pop-up window shows the issue time of the drawing and a default valid time. If the configuration file permits, select a different length of time that the object is valid. The valid time is not used within CIDD.
The pop-up window allows space for entering a comment. The comment is part of the data exported with the drawing.
When all changes have been completed to user changeable fields, click on Export to export the overlay from CIDD. Exports must be imported by CIDD or other programs to be of any use. See Section _____ ``Files for Programming'', later in this manual for information about writing a program to import drawings for use in other programs.
It is possible to take drawings exported from CIDD and import them back for use as overlays. This process does not require programming. To import drawings back into CIDD, start the drawing program with the command:
exprt -oprds_in_pope &
(in the script file ``cidd'' to replace the command ``exprt &''). Then output from the Draw program is directed into the input of the overlay program.

E.1 I entered the date and time and nothing happened. Why?
Answ: Hit return to enter the new date/time.
E.2 My data didn't show up. Why?
Answ: Check the server to see if it died and then check date, times, etc.
E.3 What does it mean when CIDD changes my requested ``movie loop start time''? For example, I might request a start time of 22:07 because I know I have a data file at that time, cidd changes the start time to 22:05 and then displays the 22:07 file.

If you've landed here, you're probably wondering a little bit about me. Like the header reads, I like to think of myself as a software developer, blogger, and podcaster. Being creative is both a blessing and a curse because, when I'm not coding, writing, or recording, I can be found learning about other creative pursuits, or enjoying the wonderful creations of others. At the moment, this means I'm listening to a lot of podcasts and reading philosophy blogs.
 Want to learn more? Feel free to follow some or all of the links below.
I've been writing consumer and corporate software since the summer of 1994, and there's little chance of me stopping now. At the moment my passions lay with making the 10Centuries platform better as well as creating software for use in schools to help students, teachers, and staff put the computers down sooner to focus on the core purpose of learning.
My first blog started in 1997 on GeoCities, and I've had an online presence ever since. As someone who has gone to the effort of creating a blogging platform, writing is something I put a lot of effort into.
You can read it here.
Since releasing my first podcast in 2014, I've gone on to make hundreds more and help dozens of people produce their own. Some of my more popular shows have been interviews, but I also have several solo shows that discuss topics ranging from 10Centuries development to social issues.
I've been working with databases of all kinds for over two decades and have a knack for finding patterns that can answer quite a few business questions and raise a good deal more. If this is something that I might be able to help you with, just send me a message and I'll be sure to respond.

Relationship fields are used when the list of values need to be loaded asynchronously based on user input, typically because the list of values is too long to be loaded into a single list field.
To use this field, some additional setup is required. You'll need to provide your own service to load selectable options. The example below includes comments that help describe what each step is doing.
Start typing some NHL team names or cities to see how the control behaves.

Brillouin Zone Viewer¶
Try out the interactive visualizer below. Controls are as follows:
Rotate: Drag with left mouse button held down
Zoom: Mousewheel
Example¶
This piece of Javascript code shows an example of loading the viewer into a an
HTML element that has been given the id canvas
. This example assumes
that the global variable installation has been used, but it can be very simply
changed to also work with the module installation by adding the proper imports
and changing the BrillouinZoneViewer
constructor call.
// Find the element in which the visualizer will be embedded into. It
// determines the visualization canvas size.
let canvas = document.getElementById("canvas");
// Viewer options
let options = {
controls: {
enablePan: false
},
view: {
fitMargin: 0.075,
},
layout: {
viewRotation: {
alignments: [
["up", "a"],
["front", "segments"],
],
rotations: [
[0, 1, 0, 45],
[1, 0, 0, 25],
],
}
},
basis: {
color: "#fff",
},
kpoints: {
label: {
color: "#fff",
}
}
};
// Initialize viewer
let viewer = new materia.BrillouinZoneViewer(canvas, options);
// Define structure and load into viewer
let reciprocal = {
basis: [
[-0.15735, 0.15735, 0.15735],
[0.15735, -0.15735, 0.15735],
[0.15735, 0.15735, -0.15735]
],
segments: [
[
[0, 0, 0],
[0.5, 0, 0.5],
[0.5, 0.25, 0.75],

["F", [0.625, 0.25, 0.625]],
]
}
// Load structure into viewer
viewer.load(reciprocal);
Loading a structure¶
You can load data to the viewer by calling the BrillouinZoneViewer.load()
method. Check the API for the supported parameters.
Options¶
The options that are given in the constructor are passed to the
BrillouinZoneViewer.setOptions()
method. These options are provided as a
nested Javascript object. Check the API for the supported parameters. At any
time you can also manually call this method to change the options. You can also
use this method to only update a subset of the options.

My name is Kris Shanks and before starting DBC I worked as a biology teacher.
Right now I'm teaching at the Santa Rosa Junior College
My gradutate work was in Mycology, the study of mushrooms.
Some wild mushrooms are very tasty. Some are deadly poisonous. There's no way to tell the difference except to know the species in question. Some of my favorite edible species include the following
