One of the most famous debuggers available on Linux and general Unix based systems is the GNU Debugger, well known as GDB. This section do not aim to explain how GDB works, but it specify the minimum requirements to make it work and be able to trace Monkey program properly.
If you want to get more details about GDB and it features, please refer to the official documentation from the GNU site:
http://www.gnu.org/software/gdb/documentation/
In order to use GDB, your Linux system must have the following tools:
Monkey must be compiled with debugging symbols, those can be enabled on configure time appending the --debug parameter, e.g:
$ ./configure --debug
after compile through make command, the Monkey binary file will contain debugging symbols, you can do a simple check with the file command:
$ file bin/monkey
bin/monkey: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=f15b588d793ddf095c294d418aa8c834e330f738, not stripped
the output of the file command should indicate at the end not stripped.
Running GDB is pretty straighforward, from the command line you need to use the gdb program name and append the Monkey binary file:
$ gdb bin/monkey
GNU gdb (Ubuntu 7.7-0ubuntu3) 7.7
Copyright (C) 2014 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later
(gdb)
When reach the GDB prompt (gdb), you can start running Monkey, or before that specify specific debugging instructions such as breakpoints.
On this simple test we will run Monkey under GDB and signal the Monkey process to simulate a segmentation fault, on that moment GDB will trap the exception and return back the control:
$ gdb bin/monkey
$ gdb bin/monkey
GNU gdb (Ubuntu 7.7-0ubuntu3) 7.7
Copyright (C) 2014 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later
(gdb)
Once in the GDB prompt, launch Monkey issuing the run GDB command:
(gdb) run
Starting program: /home/edsiper/coding/monkey/bin/monkey
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

[+] 4 threads, 126 client connections per thread, total 504
[+] Transport layer by liana in http mode
[+] Linux Features: TCP_FASTOPEN SO_REUSEPORT
You should see a similar output as the described above, the first step now would be to identify the Monkey process identificator or PID from the given output. On this case the PID is 19093:
[+] Process ID is 19093
From a different terminal we will signal the main process through the kill command issuing a SIGSEGV signal to emulate a segmentation fault:
$ kill -SIGSEGV 19093
Going back to the terminal where GDB and Monkey are running, we catch the segmentation faul event:
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff76b3d7d in nanosleep () at ../sysdeps/unix/syscall-template.S:81
../sysdeps/unix/syscall-template.S: No such file or directory.
(gdb)
If desired, the backtrace command through the bt shortcut can be used in GDB to obtain a detailed trace of when the problem was faced:
(gdb) bt
#0 0x00007ffff76b3d7d in nanosleep () at ../sysdeps/unix/syscall-template.S:81
#1 0x00007ffff76b3c14 in __sleep (seconds=0) at ../sysdeps/unix/sysv/linux/sleep.c:137
#2 0x000000000041484e in mk_server_loop (server_fd=-1) at mk_server.c:90
#3 0x0000000000406bc3 in main (argc=1, argv=0x7fffffffdf08) at monkey.c:350
GDB can be used mostly when troubleshooting a Segmentation fault or tracing specific variables changes within others, as said, is suggested to refer to the official GDB documentation for more details.

Neil Jones won't compete on Strictly Come Dancing this weekend as Alex Scott partners with Kevin Clifton
The professional announced that he is still nursing a muscle injury and will not compete alongside Alex Scott.=
by James Rodger, https://www.facebook.com/jamesrodgerjournalistNeil Jones will not dance in the upcoming Strictly Come Dancing show.
The professional announced that he is still nursing a muscle injury and will not compete alongside Alex Scott.
She will instead be partnered for the second time by last year's winner Kevin Clifton.
Jones announced on Strictly: It Takes Two that he would be ready to train again on Monday, assuming his celebrity partner makes it through the weekend.
He said: "I won't be dancing. I've tried, but it's just not ready yet.
"I'll be fine if I rest it this weekend."
He added to Scott: "You nail the dance, go through, then I'm ready on Monday morning."
The former Arsenal player said that it had been a challenging week without her usual partner, but she is lucky to still be dancing.
She said: "It has been a strange week to be honest.
"My partner, I'm used to him. It's really different dancing with someone else.
"I can sit here and moan. Poor Will doesn't get to dance."
Clifton said that his temporary partner has been "fantastic" and he hopes to keep her in the competition long enough to return to Jones.
He and Scott will dance the American Smooth in the next instalment of Strictly, which airs on BBC One this Saturday.


The SKY UX accessibility analyzer tool allows you to run aXe automated accessibility tests as part of your end-to-end testing. aXe is an open source library of automated accessibility rules that is integrated into SKY UX to identify potential issues for a subset of the Web Content Accessibility Guidelines 2.0 Level A and AA success criteria.
To use the accessibility analyzer, you add
For SKY UX guidance on accessibility best practices, see accessibility recommendations.
To use the accessibility analyzer in an e2e spec, you manually import the accessibility library at the top of the spec file. This allows you to add the accessibility analyzer anywhere in the e2e spec.
After you import the accessibility library, you can run aXe tests by including the expectation.
You should include the expectation at any point in your script where you introduce new UI elements into the DOM. For example, include the expectation when pages or views load, when modals or repeater sections open, and when tab panels change.
To enable or disable accessibility rules for e2e tests, use the
To disable individual rules, add the

For additional guidance on designing, coding, and testing accessible experiences with SKY UX, see the accessibility documentation.
When you include accessibility rules in your e2e tests, you may run into errors that uncover accessibility issues. Here is an example of an error message that appears in the command log when you run
The first line of the error message indicates what failed. It lists the name of the rule that failed and a detailed description that includes the WCAG 2.0 success criteria numbers. On the next line, the error message provides the URL for the rule definition to help address the failure. And finally, the error message lists the DOM elements where the failure was identified.

This reproducible R Markdown analysis was created with workflowr (version 1.2.0). The Report tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.
The command set.seed(20181125)
was run prior to running the code in the R Markdown file. Setting a seed ensures that any results that rely on randomness, e.g. subsampling or permutations, are reproducible.
Great job! Recording the operating system, R version, and package versions is critical for reproducibility.
Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility. The version displayed above was the version of the Git repository at the time these results were generated.
Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish
or wflow_git_commit
). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:
Ignored files:
Ignored: .Rhistory
Ignored: .Rproj.user/
Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.
These are the previous versions of the R Markdown and HTML files. If you’ve configured a remote Git repository (see ?wflow_git_remote
), click on the hyperlinks in the table below to view them.

These text products are listed under the header ACUS74. They can be found on the National Weather Service FTP server.
The following reports were obtained:
The links above point to the latest ACUS74 product issued by the respective NWS office. Therefore, it is possible that by the time you have read this article, the content of the text product has changed. Because of this, the rds data files have been saved to this website’s GitHub repository.
All times reported are in UTC. Pressure observations are in millibars. Wind and Gust observations are in knots.
The following libraries were used in this article:
library(dplyr)
library(glue)
library(lubridate)
library(purrr)
library(stringr)
library(tibble)
To load the data, I just put the links into a named list. I originally had considered keeping the data separate by NWS office but determined this was not necessary.
The code below looks for the data file mentioned earlier and, if it exists, loads the txt
vector. Otherwise, each of the text products will be collected for parsing.
rpts <- c(
"bro" = "acus74.kbro.psh.bro.txt",
"crp" = "acus74.kcrp.psh.crp.txt",
"ewx" = "acus74.kewx.psh.ewx.txt",
"hgx" = "acus74.khgx.psh.hgx.txt",
"lch" = "acus74.klch.psh.lch.txt",
"lix" = "acus74.klix.psh.lix.txt"
)
# Read data
txt <- map(rpts, ~readLines(here::here(glue("./data/{.x}"))))
Each text product contains several sections:
Section A. Lowest Sea Level Pressure/Maximum Sustained Winds and Peak Gusts
Non-METAR Observations
Section B. Marine Observations
Section C. Storm Total Rainfall
Section D. Inland Flooding (not collected)
Section E. Maximum Storm Surge and Storm Tide (not collected)
Section F. Tornadoes
Section G. Storm Impacts by County (not collected)
Not all sections will contain data. For this article, all data collected was that which contained a latitude and longitude position.
Each section contains a data header:
A. LOWEST SEA LEVEL PRESSURE/MAXIMUM SUSTAINED WINDS AND PEAK GUSTS
---------------------------------------------------------------------
METAR OBSERVATIONS...
NOTE: ANEMOMETER HEIGHT IS 10 METERS AND WIND AVERAGING IS 2 MINUTES

Additionally, a subsection of A exists:
NON-METAR OBSERVATIONS...

MINUTES INDICATED UNDER MAXIMUM SUSTAINED WIND IF KNOWN
---------------------------------------------------------------------
LOCATION ID MIN DATE/ MAX DATE/ PEAK DATE/

---------------------------------------------------------------------
This subsection was added in as part of Sectoin A but is indistinguishable in the parsed dataset.
Observation examples are inluded in the relevant section below.
Numerous observations contain remarks (identified in the dataset by ends_with("Rmks")
). Every section contains a Remarks footer; however, this may not be populated and, therefore, not every observation with a .Rmks
variable would have additional Remarks listed in the text product. The additional Remarks were not collected.
The .Rmks
legend is identified in the footer of each text product as:
“I” - Incomplete data
“E” - Estimated
All .Rmks
variables in the datasets are either NA or “I”.
Sections A and B may also contain additional anenometer height and wind-averaging period variables on a third line. This data was not collected but could easily have been; I did not feel it was relevant to this article.
A typical observation in Section A or B will look like the following:
RCPT2-ROCKPORT
28.02 -97.05 941.8 26/0336 I 017/059 26/0154 I 016/094 26/0148 I
There are 15 variables in the observation above (in order as they appear, with the example text):
ID
(RCPT2)
Station
(ROCKPORT)
Lat
(28.02)
Lon
(-97.05)
Pres
(941.8) [barometric pressure, mb]
PresDT
(26/0336) [date/time of Pres
observation, UTC]
PresRmks
(I) [incomplete pressure observation]
Wind
, WindDir
(017/059) [wind speed, kts, and wind direction]
WindDT
(26/0154) [date/time of preceeding wind observation, UTC]
WindRmks
(I) [incomplete wind observation]
Gust
, GustDir
(016/094) [maximum gust, kts, and direction]
GustDT
(26/0148) [date/time of preceeding gust observation, UTC]
GustRmks
(I) [incomplete gust observation]
Every observation has an empty line before and after which can be used as a delimiter to spilt observations.
To extract the relevant sections, I loop through the text products (txt
) and identify where Section A and Section C begins. With these numerical indices, I can extract both sections, assigning the subset to slp_raw
.
slp_raw <- c(map(txt, ~.[grep("^A\\.", .):grep("^C\\.", .)])) %>%
flatten_chr()
From there, I identify all vector elements that begin with a latitude and longitude field. I counted these values (slp_n
) so that I know exactly how long my final results will be (and to check progress as I move along, making sure I haven’t inadvertently removed anything).
Once I know where the observation indices are (slp_obs_n
) I can find the station identification by calculating slp_obs_n - 1
; this gives me slp_stations_n
.
slp_obs_ptn <- "^\\d\\d\\.\\d\\d\\s*-*\\d\\d\\d*\\.\\d\\d.+"
slp_n <- sum(str_count(slp_raw, slp_obs_ptn))
slp_obs_n <- str_which(slp_raw, slp_obs_ptn)
slp_stations_n <- slp_obs_n - 1
Before merging the two vectors, I found some station values were not all the same length; I felt this would be beneficial with the regex. I create slp_stations
, first trimming all values then finding the max length value. With the max length, I rounded up to the nearest ten and padded all all values to the right.
The last bit of manipulation involved replacing the first “-”, if available, with a “\t” character. This also helped me make it easier to split variables ID
and Station
since Station
would contain additional “-” characters.
slp_stations <-
slp_raw[slp_stations_n] %>%
str_trim() %>%
str_pad(width = round(max(nchar(.)), digits = -1), side = "right") %>%
# Replace first "-" with "\t" to help split ID and Station
str_replace("\\s*-\\s*", "\t")
Note that the code above split ID
“TXCV-4” which would later be corrected.
Finally, I subset slp_obs
and then with slp_stations
make vector slp
.
# Load observations and trim
slp_obs <- slp_raw[slp_obs_n]
# Combine stations and obs
slp <- str_c(slp_stations, slp_obs)
Following is a look at the head of slp
:
head(slp, n = 5L)
[1] "KBRO\tBROWNSVILLE INTL ARPT 25.91 -97.42 1002.9 25/1153 300/022 25/1853 290/032 25/1753 "
[2] "KHRL\tHARLINGEN VALLEY INTL ARPT 26.22 -97.66 1003.6 25/1252 310/023 25/1841 310/033 25/1852 "
[3] "KPIL\tPORT ISABEL ARPT 26.15 -97.23 1001.9 25/1253 300/024 25/1553 300/034 25/1453 "
[4] "KBKS\tBROOKS COUNTY ARPT 26.20 -98.12 1002.2 26/0215 290/019 26/0215 290/027 26/0215 "
[5] "KTXS33 26.13 -97.17 1003.0 25/2240 999/999 99/9999 999/999 99/9999 "
ID
], Station [Station
] (opt)Matching ID
and Station
is easier after switching the first “-” with a “\t”. Station
is optional. To find the end of the string I simply looked for the latitude pattern that would follow.
# ID-Station
"(\\w+)\t*(?<=\t{0,1})(.+)(?=\\s+\\d{2}\\.\\d{2})",
Lat
]Latitude was also very easy to extract. The pattern just looks for four digits with a decimal splitting in half.
# Lat
"\\s+(\\d{2}\\.\\d{2})",
Lon
]Extracting Longitude was a little bit more of a challenge. Most observations have a negative longitude value (since occurring in the northwestern hemisphere). This was accurately reflected in the text products; mostly. Some values did not contain the leading “-” such as Station
“KEFD”:
slp[grep("^KEFD", slp)][2]
[1] "KEFD 29.62 95.17 1003.4 29/1650 160/027 26/1750 360/036 29/2150 "
To accomodate the possibilities, I had to be loose with the number of digits expected in addition to making the negative sign optional.
# Lon
"\\s+-*(\\d{2,6}\\.\\d{2})",
Pres
] optExpected pressure values would have a format like \\d{3,4}\\.\\d{2}
. Some observations had values of “9999.0” which clearly were invalid (expected ranges were roughly between 940 and 1010). These would later be cleaned up.
# Pres
"\\s+(\\d{1,4}\\.\\d{1})*",
PresDT
] optPresDT
was initially split to extract the date value first (PresDTd
) followed by the “%h%m” value (PresDThm
). The general format, “\d{2}/\d{4}” would not work primarily because many observations contained the text “MM” or “N/A”.
Additionally, some observations also held the value “99/9999”. This would be accepted by the default format but would fail when converting the values to a valid date/time variable. These would later be cleaned.
With this, I ended up being very generous with the regex.
# PresDTd, PresDThm
"\\s+(\\w{1,3}|N)*/*(\\w{1,4})*",
PresRmks
] optAs noted previously, some Pres
variables may be incomplete for unknown reasons. These values would be indicated with the letter “I” as noted in the “RCPT2” example earlier.
# PresRmks
"\\s+(I)*",
WindDir
], Maximum sustained winds (opt) [Wind
]Variables WindDir
and Wind
were split with a “/” character. However, again, not all values were numeric as expected, such as “LOPL1”:
slp[grep("^LOPL1", slp)]
[1] "LOPL1\tLA OFFSHORE OIL PORT 28.88 -90.03 998.1 07/2216 080/029 07/2011 090/037 07/1811 "
Invalid values such as “999” would later be marked as NA
.
# WindDir, Wind
"\\s+(\\w{3})/(\\d{3})",
The remaining variables followed generally the same rules as similar variables above (i.e., GustDir
for WindDir
, GustDT
for WindDT
, etc.). The final str_match
call brought all expected observations in order.
# Begin extraction. Move to dataframe and rename variables.
slp_df <-
str_match(
slp,
sprintf("^%s%s%s%s%s%s%s%s%s%s%s%s$",
# ID-Station
"(\\w+)\t*(?<=\t{0,1})(.+)(?=\\s+\\d{2}\\.\\d{2})",
# Lat
"\\s+(\\d{2}\\.\\d{2})",
# Lon
"\\s+-*(\\d{2,6}\\.\\d{2})",
# Pres
"\\s+(\\d{1,4}\\.\\d{1})*",
# PresDTd, PresDThm
"\\s+(\\w{1,3}|N)*/*(\\w{1,4})*",
# PresRmks
"\\s+(I)*",
# WindDir, Wind
"\\s+(\\w{3})/(\\d{3})",
# Wind DTd, WindDThm
"\\s+(\\d{2,3})*/*(\\d{3,4})*",
# WindRmks
"\\s+(I)*",
# GustDir, Gust
"\\s+(\\w{3})*/*(\\d{3})*",
# GustDTd, GustDThm
"\\s+(\\d{2,3})*/*(\\d{3,4})*",
# GustRmks
"\\s+(I)*"

Section C of the text products listed recorded rainfall observations across the Texas and Louisiana area. These observations were similar in format to those of pressure:
COLETO CREEK GOLIAD CKDT2 9.42 I
28.73 -97.17
The following fields were extracted:
Location
(“COLETO CREEK”)
Count
(“GOLIAD”)
Station
(“CKDT2”) opt
Rain
(“9.42”)
RainRmks
(“I”)
Lat
(“28.73”)
Lon
(“-97.17”)
Extracting these observations followed the same premise for that of slp
; identifying the latitude lines then subsetting those indices and the previous indices and combining into a vector.
Unlike slp
, there were no surprises in cleaning this data. The regex used:
rain_df <- str_match(rain,
pattern = sprintf("^%s%s\\s+%s\\s+%s\\s*%s\\s+%s\\s+%s$",

Section F lists reported tornadoes for each region of responsibility. Some NWS offices reported no tornado observations. Others, such as Houston, reported at least a dozen.
An example observation is as follows:
4 NNE SEADRIFT CALHOUN 25/2114 EF0
28.43 -96.67
FACEBOOK PHOTOS AND VIDEO SHOWED A BRIEF TORNADO TOUCHED DOWN ON
GATES ROAD NEAR SEADRIFT. A SHED AND CARPORT WERE DESTROYED AND A
FEW TREES WERE BLOWN DOWN. RATED EF0.
Each observation, again, was preceeded and proceeded by an empty line.

Extracting the first two lines used the same technique as previous. However, extracting the Details
required a little creativity since many spread over several lines.
To do this, I took the values of tor_y_n
which marked the indices of the latitude/longitude positions. Then, I created vector tor_z_n
to identify all “^\s+” elements in the original vector, tor_raw
. With this, I was able to identify the first “^\s+” index following the latitude/longitude line, t_a
and then take the very next index, t_b
.
Apologies for the non-descriptive names; I was lacking ingenuity.
With t_a
and t_b
, I used map2
through tor_raw
to extract each subset. From that point there was some cleaning to bring the lines together as needed. If you have any better (even if slower, but more creative), I would love to hear them! I may have tried to get too creative with this task.

# The Visual Component Library “VCL“ ## Modular, extensible CSS Thomas Hoppe in 2019 --- # What is it?
A **modular** and **extensible** approach to CSS for the era of component-based Web application development.
- Modular, not a framework, 100% JS-free at runtime - For static sites and MV* framework driven SPAs (EmberJS, Angular, React...) - Does not break your build process, it's part of it - Existing library of 85 ready-to-use modules --- # Terminology __Component__: A self-contained UI element like a button __Module__: An NPM module containing 1 - n components - __Theme__: A module which only defines variables for other components __Theme terms__: High level theme defining colors, shades and fonts --- # Technical Basis - [Preprocessor](https://github.com/vcl/vcl/tree/master/tools/preprocessor) based on [postcss](http://postcss.org) - [npm](https://www.npmjs.org/) as package management vehicle and module registry --- # Why is it _modular_? Because components are packaged as NPM modules which can be: - from the VCL org's repository - third parties - your own ones This allows you to use exactly the modules you need to cover the styling needs of a project. --- # How is it _extensible_? It is in several ways: - You can create your own components - You can extend existing components by adding CSS rules - You can adapt existing components by overriding styles and/ or variables Everything through modules Extensions can thus seamlessly be integrated a build process --- # Installing Modules ```shell $ npm install vcl-button ``` --- # “Running“ the Demos of a Module ```shell $ git clone https://github.com/vcl/vcl.git $ cd vcl/modules/date-picker $ npm install $ npm start ``` This will: 1. install the `vcl-preprocessor` 2. install all dependent VCL modules 3. Build the styles and copy stuff to the `build` folder 4. Start a web server, serving the `build` folder 5. Open your browser to show all demos from the `demo` folder --- # Using Modules The CSS `@import`-statement is used to import modules and files: Import a module via ```CSS @import "
" ``` Import a local file via ```CSS @import "
.styl|css" ``` --- # Anatomy of a Module See what makes up a module using the example of the _button_: [https://github.com/vcl/vcl/tree/master/modules/button](https://github.com/vcl/vcl/tree/master/modules/button) This definition in `package.json` specifies the index style file: `"style": "index.styl"` It functions in the same way as the `main` property for JS-modules. --- # Soft Dependencies Soft dependencies via `devDependencies` are used to specify the dependencies of modules to run the demos. An example `package.json`: ```JavaScript "devDependencies": { "normalize.css": "^7.0.0", "pre-commit": "^1.0.6", "@vcl/build-demo": "^0.4.0-2", "@vcl/default-theme": "^0.2.0", "@vcl/default-theme-terms": "^0.2.0", "@vcl/font-awesome": "^0.3.0", "@vcl/icon": "^0.2.0", "@vcl/preprocessor": "^0.3.0-2" } ``` --- # Real World Example Typical usage is best explained by a typical `index.styl` of a web app: ``` @import "@vcl/default-theme-terms" ← Use the terms of the default theme @import "@vcl/default-theme" ← Use the default theme @import "./vcl-var-override.styl" ← Override some vars @import "@vcl/core-modules" ← Use the collection of core modules @import "@vcl/font-awesome" ← Use font awesome @import "./own-modules.css" ← Add some own stuff ``` --- # Current Module Stock - There is a collection of **~70 __core modules__** * with components ranging from typographical styles for text, links, lists etc. to complex widgets like a date picker. - They provide roughly wahat you can find in Twitter Bootstrap - ~85 Modules from the VCL org's repos
Check the **[Generated Docs of all Core Modules](https://vcl.github.io/)**. --- # WARNING, it is opinionated - CSS code is written using the [white space significant syntax](https://www.npmjs.org/package/css-whitespace), `.styl` suffix - You can also use plain CSS for your components - Uses relative units like `em`, `rem` everywhere (except for some borders) - camelCased class naming, like `vclFlipSwitch` - Embraces flexbox - More about this in the [guidelines](https://github.com/vcl/vcl/blob/master/doc/DEVELOPMENT.md) --- # Browser Compatibility Is mainly a build time decision, how you parameterize [autoprefixer](https://github.com/postcss/autoprefixer). As a result, even IE8 is possible for many components. On the other hand some components use _flexbox_, _transitions_, _media queries_ etc. which are not available in older browsers. --- # Creating Builds 1.) Via CLI ```shell $ npm install -g @vcl/preprocessor $ vcl-preprocessor index.styl dist/compiled.css ``` 2.) `package.json` script ```JavaScript "scripts": { "build-css": "vcl-preprocessor index.styl vcl.css" } ``` 3.) [Gulp task](https://github.com/vcl/vcl/tree/master/tools/gulp-vcl-preprocessor) --- # The Doc Generator The [doc-gen](https://github.com/vcl/vcl/tree/master/tools/doc-gen) allows to generate a browsable catalog of all VCL modules used in a project. - The documentation and the demos can be browsed conveniently - Includes all VCL modules in the dependency tree (“recursive“) - Completely introspection based; no registry or manual enumeration required --- # Doc related Module Meta Data in `package.json` The doc-generator is fed by the `categories` part of the meta data. - A module can have multiple categories - The priorities affect the sort order in the menu of the generated documentation ```JavaScript "vcl": { "categories": [ { "title": "Buttons", "itemPriority": 10, ← Order of the category "priority": 80 ← Order of the module within the category } ] } ``` There is a [list of categories](https://raw.githubusercontent.com/vcl/vcl/master/doc/component_categories.yml) but it's not mandatory to use them. --- # Creating Docs 1.) Via CLI ```shell $ npm install -g @vcl/doc-gen $ vcl-doc-gen --entry ./package.json --output doc.html ``` 2.) Via `package.json` script ```JavaScript "scripts": { "doc-gen": "vcl-doc-gen && http-server ./vcl-documentation", } ``` --- class: center, middle Check the **[VCL tutorial](https://github.com/vcl/vcl/tree/master/doc/tutorial)** project to see everything put together. --- # Status The VCL has come quite a long way, initiated as a monolith years ago. It's battle proven in: - Static web sites - Single page app based web sites - Mobile apps - Enterprise apps We are on a conservative **0.4.0 version level** that we released in spring 2019. Of course we adhere to [semver](http://semver.org/). The 0.2.x series of modules is published on npm. --- # Open Issues / Roadmap - Enhance documentation of modules - RTL support - Even more components - Support for [@apply](http://tabatkins.github.io/specs/css-apply-rule/#at-ruledef-apply) based extends for easy theme extension - Support themes better in doc-gen/ doc-client - Ability to scope modules to a web component via [ICSS](https://github.com/css-modules/icss) --- # Who's behind it? - Mainly created and maintained by [n-fuse](http://www.n-fuse.co) employees - 6 comitters currently **We are open for your contributions!** --- class: center, middle # Thank you

Array or Hash? what's it gonna be?
August 16, 2015
So there are arrays and there are hashes. Sound familiar? Probably not. The truth is it's really very simple and it's really very very important!
What are arrays?An array is a set of objects grouped together. These objects can all be of the same type (ex. An array of numbers) or they can be a mix of different types (ex. An array of numbers and symbols). In simple words you can imagine an array as a container that you can store your stuff in, with every item having a numbered label on it, if you know the number you can easily find the item. You can also name the entire container (ex. My_old_photos_container).
An array looks like this [object_1,object_2,object_3,……..]. The first object in the array has the number/label 0, the second item has the number/label 2 and so on.
You see, that wasn't so difficult. Now you're ready to know the secret of what makes arrays so special. Once you have objects grouped together, you have power to manipulate these objects in many ways. You can transform objects altogether or one by one, you can call an object by its index number, you can remove/add objects, and much much more.
If you want to know more about arrays, I recommend the following documentation.
What is a Hash?A hash is very similar to an array, except that instead of an index number each item in a hash can have a (key). A Key can be anything, it can be a number, a word, a symbol, etc. This way a hash is set of (key/value) pairs. Just like an array, Hashes can be manipulated in many ways, allowing you to control the complete set altogether.
Hashes are very useful, one example is having a record of names as keys and driving license numbers as values, using such hash table, you can search for a person's name (key) and you'll immediate get his/her license number. Now think bigger, what if we have an array stored as the value, this array can hold a lot of data about a certain person, by calling this person's name, you can immediately get his entire data (of course you have to store this data first).
Hash tables look like this: { Key_1: value_1 Key_2: value_2 ……… ……… }
For more information about Hashes, I recommend checking out this documentation.


DAUGHTERS OF THE DUST A film review and history by Manish Malhotra Copyright 1992 Manish Malhotra
There have been a couple of reviews saying two very different things about this film. It seems many people don't know the history of the film, so I decided to post this. This article contains information about the film, its history, and a small review.
There was a special screening of this film at the University film theater at Duke. Before the movie started, there was a brief introduction about the history of this film and why it was made. The film tells the life of people of an African tribe. Years ago, they were brought as slaves to America. Many members of this tribe still live in islands off the east coast near South Carolina and Georgia. They have preserved the original customs despite the fact that few miles across the ocean lies America, with a culture totally different!
These people have lived peacefully since the beginning of the century. However, their existence is now threatened due to encroachment on these islands (I don't remember exactly what, perhaps commercial construction and tourism development.) The film is supposed to bring awareness to the American society of what these people stand to lose if that process continues. A court case is going on regarding this dispute of land of those islands. There is an organization that is fighting for the rights of these people and survives on charity money. The director (I think a woman) had many difficulties obtaining funding for the film. It took her almost twelve years to complete the film.
The language spoken in the film is the language that these people speak. I think it is English mixed with their original language. I would rather call this film a documentary. Personally, I did not like the film. It is a very poorly made film and sustains the interest for a while only because of its beautiful photography. Oh! I hate to think that natural beauty of these islands would be spoiled because of commerce. Another problem I had with the film was its length. It is just too long for what it is trying to say. The plots don't even have to be there. My feeling is that the director wanted to make a documentary but for the reasons of collecting money (for the same organization), she tried to make it more commercial by adding loose plots of which she did a very poor job. After half an hour of the film, the audience begin to expect some plot to develop. But all the plots are left partially developed.
If you decide to see this film, don't expect a film but think of it as a documentary. If you believe in helping this organization, then think of the ticket money as the charity. Enjoy the beautiful photography and gain some insights into the culture of one of the African tribes.

This tutorial covers the data types in GLSL ES and how to use them.
In GML, you can set variables to any value from tiny fractions to large integers to booleans without worrying about data types. However, in shaders you need to initialize what data type you are using for each variable, allowing shaders to be faster and more precise.
The first thing to learn about shader variables is the data types. You can use any of the following types:
To declare your variables in code you must specify the type before the variable name and shader syntax requires a semi-colon at the end of the declaration:
//Floats must include a decimal point.
float A = 5.0;
//You can declare the variable to set later:
//Integers must exclude a decimal point.
int B;
//Bools are either true or false.
bool C = false,
//"D" is also a bool because of the comma after the "C" definition.
D = true;
As you can see with the integer case, you can initialize a variable's type without setting a value. This is like local variables in GM (e.g. var i = 0). Also, you can use commas instead of semicolons when defining multiple variables of the same data type. This is shown with bool "D".
Sometimes you need to convert from one data type to another and this is called "casting". To cast a value you use the replacement data type as function with the value you want to convert as the argument. Here's a quick example:
//Cast an int to a float.
float A = float(5);
//Cast a bool to an int (false = 0, true = 1).
int B = int(true);
Unlike in GML, some shader variables can contain up to 4 values at once and these values are called "components" of the variable. Vectors make it much easier to do math with 2,3 or 4 dimensions. If you want to add two vectors together you can do so with a single operation, like you would with any other variable (which will be very useful later).
So floats, vec2s, vec3s and vec4s are all floating-point numbers, so a float has 1 component while vec4 has 4. To set a vector with you use a function called a constructor which is just like a caster but can have multiple components separated by commas. Here's how it looks to initialize different variable types:
//1D scalar with a value of 1.0. Scalars don't need constructors.
float line = 1.0;
//Construct a 2D integer vector containing 1 and 2 respectively.
ivec2 square = ivec2(1, 2);
//You can include floats as components:
//Construct a 3D vector containing 1.0, 2.0 and 3.0 respectively.
vec3 cube = vec3(line, 2.0, 3.0);
//You can also include vectors:
//Construct a 4D vector containing 1.0, 2.0, 3.0 and 4.0 respectively.
vec4 tess = vec4(cube, 4.0);
You can also do the same with integers by using int, ivec2, ivec3, and ivec4. As you may have guessed, you can do the same with Booleans (bool, bvec2, bvec3, and bvec4), but they aren't used as often.
So you now know how to cast data types and construct vectors, but to extract components from vectors you need to know about "swizzle notation". There are two ways to access components.
Dotted Notation is more widely used because it can be used to access floats or vectors whereas array notation only accesses floats. Here's an example to show both methods:
//Construct a vec4 from ints for example.
vec4 A = vec4(0, 1, 2, 3);
//Get the first component of "A", 0.0.
float B = A.x;
//Get the second component of "A", 1.0.
float C = A[1];
//Reverse the component order of "A", vec4(3, 2, 1, 0).
vec4 D = A.abgr;
//This also works for setting vectors:
//Set the first two component to the last two components, vec2(2, 3).
A.st = A.pq;
It's important to tell you, you CANNOT mix components from one set with another. So you can pick between xyzw, rgba or stpq, but you can't do something like xyrg because this will cause an error.
Matrices are a special data type that contain more components than their vector equivalents. It helps to think of matrices as tables with either 2, 3 or 4 rows and columns, so a mat2 contains 2 vec2s (2x2 or 4 components), a mat3 contains 3 vec3s (3x3 or 9 components) and a mat4 contains 4 vec4s (4x4 or 16 components).
They can be initialized like so:
//Set the first and second columns with vec2s.
mat2 rotate = mat2(vec2(0.6,0.8), vec2(-0.8,0.6));
//Get the vec2 from the second column which is vec2(-0.8,0.6).
vec2 y_dot = rotate[1];
//And here are some mat3 examples:
//Alternatively, you can set all components individually.
mat3 rotate2 = mat3(0.6, 0.8, 0.0, -0.8, 0.6, 0.0, 0.0, 0.0, 1.0);
//Get the first column, second row component which is 0.8
float y_z = rotate2[0][1];
Matrices can be used to scale, rotate or skew vectors simple by multiplying a vector by a matrix. Matrix multiplication is non-commutative, meaning that the result can be different depending on the order of multiplication. You can learn more on this in the next tutorial, but for now you just need to know it's used to "transform" vectors.
"Storage qualifiers" control how you want your variable is handled. This can be used to receive vertex information, receive values from GML and more! These are the storage qualifiers and how they are used:
Variables can be grouped:
//Initialize a integer array with 5 slots.
ivec2 array[4];
//Set the 2 index value as a ivec2.
array[2] = ivec2(2,4);
//Initialize structure format.
struct sample
{
vec2 uv;
sampler2D tex;
};
//Set create a "sample" structure.
sample pixel = sample(v_vTexcoord,gm_BaseTexture);
//Get pixel's uvs.
vec2 pix_uv = pixel.uv;
//Set pixel's texture to "uni_diffuse".
pixel.tex = uni_diffuse;
Lastly, there are precision qualifiers, which can control the range and quality of variables. Modern hardware may use a higher precision than you specify, but precision qualifiers set the minimum acceptable precision (if the hardware supports it). This isn't used often, but it can be useful with cross-platform shaders. These are the three precision types:
//Set the default float precision to highp.
precision highp float;
//Set the default integer precision to lowp.
precision lowp int;
//Set the color at low precision.
lowp vec3 color = vec3(0.2, 0.4, 0.8);
Great job! You've learned about all the different data types and what they store. You've learned how to handle multi-dimensional variables (vectors) and their components. You now know how to access shader inputs (attributes, varyings, uniforms) and how to use constants, data groups (arrays and structs) and precision. This lays the framework necessary to understand functions and logic which is covered in the next tutorial. For now, pat yourself on the back and take a break if you need it!

Before the AWA widgets can be used, at least one AWA environment has to be defined by a user with admin permissions. The environments can be added in the Context Settings found under "Admin >> Context Settings".
The AWA Legend Widget shows a legend for the colors used by the AWA Job Status Widget. The following are the statuses used by the AWA widgets:
The Job Status Widget will display the current status for one or more selected AWA jobs.
If there is currently no data available, the status will be set to unknown.
This Widget supports a task that will periodically check whether the selected jobs ended with an issue and can send alerts if this is the case.
This widget will display the last x status for one or more selected AWA jobs. If there is currently no data available, the status will be set to unknown. You can choose to display statistical values for every job.
The Job with Status Widget will find Jobs based on one or multiple filters with a certain status for the last X hours. This widget is useful to list all jobs with issues for the last day.


To create a panoramic image a photographer can start by taking multiple photos of a scene. This can be done by putting the camera in continuous shoot mode or a similar setting on the specific device. A burst or a sequence of multiple images is a premises to this application.
Stitch the two example images together to one and the same image


Manual Installation¶
The CodeIgniter 4 framework repository holds the released versions of the framework. It is intended for developers who do not wish to use Composer.
Develop your app inside the app
folder, and the public
folder
will be your public-facing document root. Do not change anything inside the system
folder!
Note: This is the installation technique closest to that described for CodeIgniter 3.
Installation¶
Download the latest version, and extract it to become your project root.
Setting Up¶
None
Upgrading¶
Download a new copy of the framework, and then follow the upgrade instructions in the release notice or changelog to merge that with your project.
Typically, you replace the system
folder, and check designated
app/Config
folders for affected changes.
Pros¶
Download and run
Cons¶
You are responsible for merge conflicts when updating
Structure¶
Folders in your project after set up: app, public, system, writable
Translations Installation¶
If you want to take advantage of the system message translations, they can be added to your project in a similar fashion.
Download the latest version of them.
Extract the downloaded zip, and copy the Language
folder contents in it
to your PROJECT_ROOT/app/Languages
folder.
This would need to be repeated to incorporate any updates to the translations.

WHERE THE SKY MEETS THE LAND A film review by Steve Rhodes Copyright 2000 Steve Rhodes RATING (0 TO ****): * 1/2
Frank Müller's languid documentary, WHERE THE SKY MEETS THE LAND, is set in a remote village, 14,000 feet up, in the republic of Kirgizstan. Heavy on village minutia (washing dishes, baking bread, riding motorbikes and playing boom boxes), the film lacks anything approaching a compelling narrative. The best that could be said of it is that, with its visual splendor, it could be dramatically trimmed down and made into a dynamite travelogue.
The movie's central character is a gentle, 64-year-old Kirgiz woman, who looks at least a decade older. Some people come to resemble their dogs. This woman, thanks to her diet and the searing sun, has become the spitting image of her bread, which she bakes in a pan on an outdoor fire. Round, puffy and ruddy, her face has a worn complexion but a cherubic smile. Her prayers to God involve blessing the car and asking him for more vodka.
The film generally eschews dialog and is composed instead with long silent sections involving simple village life, much like the documentary ENDURANCE. This can have a sleep-inducing effect on the audience.
There is a subtheme of the despoliation of the environment by a new gold mine nearby. The miners, however, seem to be the happiest of all, so the message about progress destroying the local culture doesn't acquire much traction.
American movies featuring animals are obliged to include a disclaimer in the closing credits stating that no animals were harmed during the making of the film. WHERE THE SKY MEETS THE LAND could make no such declaration. Among the few scenes of any dramatic tension in the movie are a couple of sickening ones involving goats.  In another scene, we witness a goat taking the place of a polo ball in some native game. To be fair, the documentary didn't cause these events to occur. It just recorded them.
WHERE THE SKY MEETS THE LAND runs 1:15. The film is in English and Kirgiz with English subtitles. It is not rated but might be an R for the above-mentioned animal sequences. The film would be acceptable for teenagers.
The film will be playing as part of the San Francisco International Film Festival (http://www.sfiff.org), which runs April 20 to May 4, 2000. It does not currently have a United States release date.
