Dramatis Personae:
ROBERT FRIPP, modest and bashful egghead electric guitar wizard
TOYAH WILCOX, pint-sized popstrel, his wife
PATRICIA FRIPP, executive skills coach and motivational speaker, his sister
PETE SINFIELD, magician who weaves spells with words, King Crimson lyricist
Scene One. Toyah's so-called “Yoko House”, a property devoted entirely to storage of archives and memorabilia of her glittering career. Toyah is sorting through a pile of old videotapes of her appearances on Top Of The Pops, three decades ago.
Enter Robert Fripp, carrying an electric guitar.
ROBERT FRIPP : Hello, pint-sized popstrel wife!
TOYAH WILCOX : Hello Robert. Have you invented a new electric guitar technique today?
ROBERT FRIPP : Not yet, my dear, not yet.
TOYAH WLCOX : You'd better buck your ideath up! The world lookth to you for thintillating electric guitar innovationth.
Robert Fripp passes a hand over his startlingly intelligent forehead, momentarily overcome by the weight of his responsibility.
ROBERT FRIPP : I can't come up with something as fantastic as Frippertronics every day, sweetie.
TOYAH WILCOX : I don't thee why not. You jutht took a thimple feedback loop thing already practithed by many experimental guitarithtth and called it Frippertronicth with your wonderful modethty. I'm thure there are thome other techniqueth lying around that you could altho lay claim to.
ROBERT FRIPP : (sighing) I don't know. Sometimes I think my gigantic brain has taken the electric guitar as far as it can go. Perhaps I need a brand new field to which I can devote my pulsating intellect.
Scene Two. The executive boardroom of Cakes R Us, a major player in the cake manufacturing industry. Patricia Fripp is addressing the assembled executives.
PATRICIA FRIPP : OK, still the hubbub! I know I have been described as “one of the ten most electrifying speakers in North America”, but right now you have to stay calm and concentrate on cake sales figures. Let's kick some ideas around the flagpole and push envelopes into a box. Brainstorm, guys!
The executives brainstorm in various little grouplets or “idea silos”.
Scene Three. Toyah's “Yoko House”.
TOYAH WILCOX : Robert, give me a hand with thith pile of coloured vinyl copieth of my hit thingle “It'th A Mythtery”.
ROBERT FRIPP : Will do, poppet, just as soon as I have finished cogitating.
The telephone rings. Toyah picks up the receiver.
TOYAH WILCOX : Hello?
She listens for a while and then puts the phone down.
TOYAH WILCOX ; Well, Robert, that wath very exthiting. It wath your thithter Patrithia, calling from a very important conferenthe of cake executiveth in North America. They want to expand their cake buthineth to the UK by holding cake thaleth at countrythide fairth and bazaarth and jamboreeth. Patrithia thinkth you would be the perfect perthon to add gravitath and therebral heft to thuch eventth.
ROBERT FRIPP : You mean I should cast aside the electric guitar and devote myself to innovations in cake-selling?
TOYAH WILCOX : Yeth.
ROBERT FRIPP : It would certainly give me a whole new area to which to apply my giant egghead brain! I must go and see Pete Sinfield at once!
Scene Four. The palatial residence of Pete Sinfield, whose lyrics have been intoned by top prog artists such as King Crimson, Emerson Lake & Palmer, Leo Sayer and Bucks Fizz. Pete is sitting at an escritoire, writing the lyrics for a pop song with a quill upon parchment.
Enter ROBERT FRIPP
PETE SINFIELD : Hello, Robert. It's a good job my residence is palatial, with huge doorways wide enough for your superb bespectacled egghead to fit through.
ROBERT FRIPP : I need some lyrics about cake for my new project.
PETE SINFIELD : Hmm. Let the Muse descend. “The lady in white robes floats o'er the mystic lake / And on the wind are borne towards her many sorts of cake”.
ROBERT FRIPP : Brilliant! Thanks, Pete.
Scene Five. A countryside fete, somewhere in England. Inside a marquee, beside a sign bearing his wife's name, Robert Fripp proffers a tray of cakes to passers-by.
ROBERT FRIPP : Roll up, roll up. These aren't just cakes. They are an entirely new teatime snack I call Frippocakeys.
TOYAH WILCOX, PATRICIA FRIPP, & PETE SINFIELD (looking on in awestruck admiration) : Truly, Robert Fripp has brought something entirely new and original to the world of cakes.
Curtain.

Basic Bread Recipe
This is a recipe for a basic loaf of bread. The dough itself can be used however. I’ve made buns, rolls, and whole bread loafs using this same exact dough every time without a problem. Eat within 3 days as it will probably be going stale around then (as bread without preservatives and other junk should).
Ingredients
- 1 ½ cups warm water
- 2 and ¼ teaspoons Active Dry Yeast
- 1 Tsp sugar
- 2 Tbsp maple syrup, agave, or honey
- ½ Tbsp salt
- 3 ¾ cups Unbleached All-Purpose Flour (plus more for rolling / dusting)
Directions
- Proof the yeast. To do this warm ¼ cup water to about bath water heat (110 degrees F, 43 degrees C) add active dry yeast and 1 Tsp sugar. Let sit for about 10 minutes, mixture should at least be doubled in size after waiting.
- Combine rest of water, yeast mixture, maple syrup (or other sweetener), salt, and flour in a large mixing bowl and stir. The result will be a sticky, rough dough. Use a spoon to stir until well combined and when it can no longer do the job, knead and turn it in the bowl with your hands.
- Lift the dough out and lightly grease the bowl with nonstick spray or olive oil. Cover and let rise for 2 hours at room temperature.
- Transfer dough to a lightly floured work surface and knead until dough is elastic. Rule of thumb is 10 minutes of kneading.
- Place seam-side down in a lightly greased loaf pan or baking sheet. Loosely cover with plastic wrap and let rest for 45-60 minutes.
- Preheat oven to 425 degrees F (218 C)* toward the end of the dough resting time and place a metal pan (NOT glass, Pyrex, or ceramic) on the lowest oven rack. Also have 1 cup of hot water ready.
- When the oven is preheated, slash the bread 2 or 3 times with a knife, making a cut about ½-inch deep.
- Place in oven on middle rack. Then carefully pour hot water into the shallow pan on the rack beneath. Expect it to bubble and steam; then close oven door quickly.
- Bake the bread for 26 to 35 minutes, or until deep golden brown and risen. Tapping the top of the loaf should produce a hollow sound.
- Remove the bread from the oven and let rest in the pan for 5 minutes. Then carefully remove from pan and transfer to a cooling rack to cool. Let it cool completely before slicing for best results (otherwise it can be doughy in the middle).
- Store leftovers in a plastic bag at room temperature for up to a few days. Transfer to freezer for longer term storage.
Notes
- Instant yeast is not recommended as you can’t easily tell if the bread will come to life.
- For whole wheat version use 2 cups of whole wheat bread and 1 and ¾ cup unbleached all purpose flour.
- Add sunflower seeds and/or rolled oats for extra flavor/grains.
- For buns or rolls divide dough into smaller pieces before second rest. Shape them and then let the dough rest. Recommended lowering oven temperature to 350 F and not using water as those will result in a hard crust and potentially dry interior.

...is to support and improve Creative's work through the use of technology
We do this in three ways
Advise proposal teams on how to best include technology
Develop new, and customize existing, technology tools to achieve impact and scale
Implement technology-driven products & solutions in projects
The Lab is structured with liaisons for each practice area and technical expertise in cross-cutting sectors
Business Development
During Business Development, the Lab can assist in all four of the main phases to create innovative and winning solutions…
Implementation
The Lab can provide support at all stages of a program, from startup to close out and from the individual activity level to the entire program. We do this by...
Generates data for us to analyze in the communites and regions we work in
Can act as an activity that engages marginalized groups (women, youth, minorites, etc...) bringing them into the decision making process
Puts un-mapped communites litterally on the map!
GIS and M&E
Geographic Scale + Your Indicatiors
Defining a minimum geographic scale for indicator data in the Mission-wide PMP and within project teams in the Project MEL Plan, will result in a common geographic denominator among indicators, and will allow for the data to be used for a range of performance management needs throughout the Program Cycle.
Let's build a gazetteer!

Chapter 5 Report
Literate programming, an idea developed by Donald Knuth, mixes code that can be executed with regular text. The files you create can then be rendered, to run any embedded code. The final output will have results from your code and the regular text.
R has a collection of packages that extend these ideas of literate programming, allowing you to
create reports that interweave R code, the results from that code, and text. This collection
include the packages knitr
and rmarkdown
. I believe both are automatically installed to your
computer when you install RStudio.
This section will walk you through some of the basics of creating two types of reports using RMarkdown: a basic RMarkdown report and a dashboard. The R project directory you downloaded in the “Prerequisites” section includes example files for both in its “reports” subdirectory.
5.1 RMarkdown
The RMarkdown framework makes it very easy to create nice reports from R code in RStudio.
Here are the basics of opening and rendering an R Markdown file in RStudio:
- To open a new R Markdown file, go to “File” -> “New File” -> “RMarkdown…”. In the box that pops up, chose a “Document” in “HTML” format.
- This will open a new R Markdown file in RStudio. The file extension for R Markdown files is “.Rmd”.
- The new file comes with some example code and text. You can run the file as-is to try out the example. You will ultimately delete this example code and text and replace it with your own.
- Once you “knit” the R Markdown file, R will render an HTML file with the output. This is automatically saved in the same directory where you saved your .Rmd file.
- Write everything besides R code using Markdown syntax (explained below).
To include R code in an RMarkdown document, you need to separate off the code chunk using the
following syntax (here, the code assigns the numbers one to 10 to the object my_vec
):
```{r}
my_vec <- 1:10
```
This syntax might look unusual, but it tells R how to find the start and end of pieces of R code when the file is processed by R. R will walk through, find each piece of R code inside these special sections, run it and create output (printed output or figures, for example). R will ignore anything not in one of these sections, including the text of the report. The output from this R processing will then pass into another program to complete rendering (e.g., a LaTeX engine for pdf files).
R Markdown files are mostly written using Markdown. To write R Markdown files, you need to understand what markup languages like Markdown are and how they work.
In Word and other word processing programs you have used, you can add formatting using buttons and keyboard shortcuts (e.g., “Ctrl-B” for bold). The file saves the words you type. It also saves the formatting, but you see the final output, rather than the formatting markup, when you edit the file (WYSIWYG – what you see is what you get).
In markup languages,30 on the other hand, you markup the
document directly to show what formatting the
final version should have (e.g., you type **bold**
in the file to end up with a document with
bold).
To write a file in Markdown, you’ll need to learn the conventions for creating formatting. This table shows the markup for some common formatting choices:
| Code | Rendering | Explanation |
|---|---|---|
**text** |
text | boldface |
*text* |
text | italicized |
[text](www.google.com) |
text | hyperlink |
# text |
first-level header | |
## text |
second-level header |
Some other simple things you can do in Markdown include:
- Lists (ordered or bulleted)
- Equations
- Tables
- Figures from file
- Block quotes
- Superscripts
See the resources listed in “Learn More” for links to some helpful resources for learning RMarkdown, including more of these Markdown formatting mark-ups.
5.2 Dashboards
In RStudio, you can also now create a “dashboard” using RMarkdown. A dashboard might be a good choice if you need to summarize or show a lot of information on a single webpage in a way that everything can be viewed in one window. Figure 5.1 gives an example dashboard (although this is just a screenshot—if posted online, the leaflet map in this would be interactive).
To create a dashboard, you’ll need to have the flexdashboard
package (Iannone, Allaire, and Borges 2018)
installed. If you have this package installed, you can create a dashboard by opening your
RStudio session and selecting “File” -> “New File” -> “RMarkdown”. In the box that pops
up, go to the “From Template” tab and select “Flexdashboard”.
The R Project with examples for this workshop includes an example file for creating a dashboard in the “reports” subdirectory’s “flexdashboard_example.Rmd” file.31 Open this file and try creating the dashboard using the “Knit” button. You can get an idea for how the code converts to elements of the dashboard by changing some of the code in the RMarkdown file.
The flexdashboard
package is extensively documented through its website, where you can find many examples of
how to create dashboards with RMarkdown.
5.3 Learn more
For more Markdown conventions, see RStudio’s R Markdown Reference Guide (link also available through “Help” in RStudio). There are several great books on knitr
and RMarkdown now;
R Markdown: The Definitive Guide is particularly
good, and includes the creater of knitr
and rmarkdown
as a coauthor.
For more on creating dashboards using RMarkdown, see flexdashboard
package’s website, which includes many examples
of code and output for these dashboards.
You can post the output of an RMarkdown file for free (note that it will be public) through RPubs. This is also a great site for exploring reports others have created using RMarkdown. For more on posting your own files to RPubs, see here.
A collection of books published with R using RMarkdown is available through
bookdown.org. You can also use RMarkdown to create your own website
with a blog using the blogdown
package, which is explained in
blogdown: Creating Websites with R Markdown.

Examples include HTML, LaTeX, and Markdown↩
You might notice that there are some other files in this subdirectory that start with “flexdashboard_example”. These are the files that are written out when you knit the RMarkdown file. You should never change these by hand, but these include the files you’ll want to share or post online as the output of the RMarkdown file (e.g., “flexdashboard_example.html”).↩


DEEP BLUE SEA RATING: 7.5 / 10 --> Very good movie
For more movie reviews and trivia, visit http://www.joblo.com/
There was a time when films like JAWS and THE SHINING (9/10) scared the beejesus out of us. Nowadays, special effects have taken over the movie industry and Hollyland expects us to be thrilled by computer-generated houses and sharks. THE HAUNTING (4/10) failed miserably at this task, DEEP BLUE SEA on the other hand, chewed right into it and bit off my thumb up!
PLOT: A team of research scientists genetically toy with sharks in order to find a cure for the human disorder of Alzheimer. When things go awry, the sharks get smarter, angrier and stronger.
CRITIQUE: In my mind, the definition of a "fun summer popcorn flick" has something to do with turning off your brain at the door, enjoying the thrills and chills of a preposterous yet interesting situation, laughing, biting your fingernails, and having a blast, whilst digging into your preferred snack de la jour (Nachos, cheese and salsa for me, thank you very much). If you go into this movie expecting to find the answers to genetic testing on animals and its ability to cure human diseases, you will be highly disappointed. If, on the other hand, you are going into this film expecting to find some cool-looking sharks chewing on human bodies, one-liners galore, over-the-top situations which hold you in bated breath, and a motley cast of diverse characters just waiting to be ripped to bits by these mutated sharks...then this puppy is definitely the summer movie for you! Think...JAWS on speed.
Unlike THE HAUNTING (4/10), this summer film doesn't rely solely on its special effects to do the trick. It adds interesting and entertaining characters, a plausible plot, some nice style, a heart-pounding score and even some genre-bending surprises here and there. I personally would have liked to have seen more of those rapid-fire sharks crunching into folk, but hey, I'm just a guy munching on nachos down here. The plot also doesn't take long to get going, and once it does, you could expect all kinds of crazy shark action. The story is obviously not rich in breadth, with a simple "shark angry-let's get away from the shark" explanation covering the rest of the film, but director Renny Harlin makes sure that we all have a blast in the meantime. Actor-wise, it is LL Cool J who steals the show with his one-liners, with the "Sam Jackson scene" being the most memorable, and the shark wrangler dude, Thomas Jane, also pulling in a fine performance. If you can't stomach scenes featuring humans being chewed up by large sharks, well guess what, stay away from this movie!
Little Known Facts about this film and its stars: The "L" in Samuel L. Jackson's name stands for Leroy. Sam was an admitted drug user until he completed drug rehab two weeks before playing a drug addict in Spike Lee's JUNGLE FEVER. Some may remember him as Stacks Edwards from Martin Scorsese's 1990 mob flick GOODFELLAS (10/10). He also played the character of "Black Guy" in the 1989 Al Pacino thriller SEA OF LOVE (7.5/10). His city of birth is Washington, D.C. Director Renny Harlin's birth name is Lauri Mauritz Harjola. He was born in Finland. He stands 6'4" and was married to tall actress Geena Davis for about four years.  He has five younger siblings. In the "wink or you'll miss it category", note that director Renny Harlin can be seen leaving the seaport facilities with the rest of some folks near the beginning of the movie. Guess he didn't want to stick around for any of the carnage, eh? This film was originally titled TIME OUT. The first scene of this film could easily be interpreted as an homage to the JAWS films.
Review Date: August 3, 1999 Director: Renny Harlin Writers: Duncan Kennedy, Wayne Powers and Donna Powers Producers: Akiva Goldsman, Robert Kosberg, Tony Ludwig, Alan Riche Actors: Samuel L. Jackson as Russel Franklin LL Cool J as Preacher Saffron Burrows as Dr. Susan McAlester Thomas Jane as Carter Blake Genre: Thriller Year of Release: 1999 ----------------------------------- JoBlo's Movie Emporium http://www.joblo.com/ ----------------------------------- (c) 1999 Berge Garabedian

Arhaan Khan eliminated from ‘Bigg Boss 13’
by BizAsia CorrespondentRecent wild card contestant, Arhaan Khan has been booted out of ‘Bigg Boss 13’ in the show’s latest eviction process.
The actor had been in a rumoured relationship with fellow celebrity, Rashami Desai, who was in the bottom three along with Himanshi Khurana and Khesari Lal Yadav. The eviction was rather surprising as the latter two had been regularly picked on for not being so active on the show.
Since his entry on ‘Bigg Boss 13’, Khan remained a close alliance to Desai, in her war of words with Siddharth Shukla.

Trump asks for questions from 'friendly reporters' during press conference
by John GagePresident Trump said during a press conference with Turkish President Recep Tayyip Erdogan that he wanted questions from only reporters that are friendly.
"A friendly person from Turkey, please," Trump said Wednesday. "Friendly — only friendly reporters, we like to see. There aren’t too many of them around."
The press conference came the same day the House Democrats held the first public impeachment hearing. Trump said he did not watch the proceedings and instead met with Erdogan.
The two met to talk about Turkey's treatment of the United States-allied Turkish forces along with Turkey's purchase of a Russian arms system. The U.S. and Turkey came to a peace agreement last month with the Kurds, which was criticized by many as the U.S. caving to Turkish demands.


Your task is to design and implement data schemas and corresponding HTTP server endpoints for a professional athlete hosting a Question & Answer session with fans.
Using an HTTP server and data store of your choosing, please implement the REST-like endpoints listed below.
Each task details a minimum set of required data attributes, add more as you deem necessary.
The routes in the task list are only suggestions, modify them however you see fit.
Be prepared to discuss any benefits, limitations, and tradeoffs of your design after the exercise.
This webpage is meant to help you test your implementation, feel free to make modifications in order to get it talking with your server.
By default, this webpage expects an HTTP server running on http://localhost:8080 that accepts and returns all data in JSON format.
It also attempts to make requests to the example routes, so if you make changes to the routes, you will also need to change the JavaScript on the page code.
Feel free to ask us any questions you may have.
When you are finished, please email your source code (including your version of this HTML file if you made any modifications) along with directions for launching the server and data store to dian@Html("@")slyce.io or give us a link to your GitHub.
*Note: All data models are expected to have some sort of id field. All user models must have at least a name attribute.
1. Create a QA session. QA sessions must have a host user, a start_time, and an end_time.
POST /qa
2. Retrieve a QA session.
GET /qa/:qa_id
3. Ask a question. Questions are within the context of a single QA session and must contain text and an asked_by user.
POST /question/:qa_id
4. Answer a question. Can assume one answer per question. An answer can allow for either text and/or image_url as a response. It must also have an answered_by user.
POST /answer/:question_id
5. Retrieve a list of questions for a given QA session. Allow for the option of filtering answered vs. non-answered questions.
Each question in the result list must contain all relevant expanded models. IE: the asked_by user, the answer (if there was one), and the answered_by user.
GET /qa/:qa_id/questions
Form fields are sent to the server as JSON in POST requests. EX: the host_name and start_time fields are sent as {host_name: value, start_time: value}. ID fields may be sent as part of the URL depending on the endpoint. EX: qa_id = 1234 is included in the URL as /qa/1234
If you see 'Access control...' type errors in the browser developer console, read the comments in the JavaScript source code of this HTML page regarding 'CORS'.

FullCalendar can display events from a public google Calendar. google Calendar can serve as a backend that manages and persistently stores event data (a feature that FullCalendar currently lacks). You must have google calendar API key, make your google calendar public and obtain your google calendar's ID. Please visit this link for all the documentation
A URL of a JSON feed that the calendar will fetch Event Objects from. FullCalendar will visit the URL whenever it needs new event data. This happens when the user clicks prev/next or changes views. FullCalendar will determine the date-range it needs events for and will pass that information along in GET parameters.
Determines the timezone in which dates throughout the API are parsed and rendered. false (default), 'local', 'UTC', a timezone string ('America/Chicago')
Each of these possible values has an effect on (1) the way event data requests are made, (2) the timezones that event dates are represented in, and (3) the timezones that other dates in the API are represented in.


Stroke is the leading cause of long term disability in the world. Over 198,750 people each year have a stroke that have effects that they must deal with for the rest of their lives. The specific disability our application is made for is the partial loss of motor skills in the hand, which are precise, coordinated movements, such as using your fingers to pick up a coin.
PVRT is an application made for patients who have had a stroke and have lost motor skills in either of their hands. This application, through the usage of games, helps the patient strengthen their hand. These games reflect exerises that many of these patients do at the physical therapist office. Instead of spending up to $420 per session at a physical therapist's office, you could simply download this application and use it with the only expenses being a one time fee for the Oculus Rift and the Leap Motion to exercise/work on their hands.


Logistic Regression¶
Logistic regression is a classification algorithm used to assign observations to a discrete set of classes. Unlike linear regression which outputs continuous number values, logistic regression transforms its output using the logistic sigmoid function to return a probability value which can then be mapped to two or more discrete classes.
The dataset is not linearly separable, so logistic regression doesn’t perform well.
Types¶
- Binary (Pass / Fail)
- Multi (Cats, Dogs, Sheep)
- Ordinal (Low, Medium, High)
Sigmoid Activation¶
The function maps any real value into another value between 0 and 1. In machine learning, we use sigmoid to map predictions to probabilities.
- Math
\[S(Z) = 1 / ( 1 + (e^{-z}))\]

There are two types of scope - global and local - and these refer to the availability of variables depending on whether the variable is declared inside (local scope) or outside (global scope) of a function.
An analogy would be like the preparation of food between a child and parent. The parent can prepare food (a variable) and this food is available to anyone including the child (global scope).
The child (a function) can also prepare food (a variable) but this food will only be available to the child (local scope) as the parent would not take food from their child.
However, there is an exception to this one-way relationship. If a variable is assigned a value but has not been declared (by writing “var” before the variable name) then it becomes a global variable even if it is written inside of a function. So this exception would be like a child gifting some food to the parent.
parentheses () - e.g. '1. Execute a function var result = doSomething()'
Grouping expressions where the expression in the parentheses is executed first, e.g.: a = (b + c) * d
Containing expressions such as in a loop, e.g.: if (a < b)
Containing parameters for functions, e.g.: function (a, b, c)
brackets []
For containing arrays, e.g.: array = [ a, b]
For accessing a location in an array, e.g.: array[1]
For accessing object properties, e.g.: object[a] = b
braces {}
For defining the start and end of a function and separate code into blocks inside functions, e.g.:
function a() {
if (a < b) {
}
}
For declaring object literals, e.g.: var object = { key: value, key: value }
single quotes '' and double quotes ""
For containing strings, e.g.: ‘This string\’s saying “Hello” to you’
There is no preference for single or double quotes but it is important to use them consistently, ensure that a different set of quotes is used within a string so the string is not cut off prematurely, and use the escape character (\) when needed for the same reason.

On April 12, 1961, Soviet cosmonaut Gagarin became the first person to enter space after flying around the earth on board the "east" spacecraft. Since then, manned space flight has roughly gone through three stages.
Before entering space for the first time, humans launched unmanned spacecraft and biological satellites to verify the safety and reliability of manned space systems and ensure the success of manned space flight. After everything became mature, a manned spacecraft was finally launched. During the flight, astronauts completed manual orientation, posture adjustment, earth observation and earth photography, and conducted scientific research and extensive technical experiments in medicine, biology, etc. The first stage of manned space flight has proved that human beings can not only survive but also work effectively under such harsh environments as overload, weightlessness, vacuum and strong radiation, laying a solid foundation for future human beings to explore and develop space in a large scale, and its value is of milestone significance.
such as the orbital maneuver flight of the spacecraft, the rendezvous and docking of the two spacecraft in space and the formation flight, to inspect the equipment and capability of astronauts' extravehicular activities, and also to carry out other scientific research work. At this stage, Soviet astronaut leonov and American astronaut E. H.White walked out of the spacecraft in spacesuits and carried out activities in space. On January 27, 1967, when the Apollo spacecraft was carrying out routine tests at cape Kennedy, three American astronauts died due to a sudden fire. On April 23, 1967, when the Soviet Union's Soyuz 1 spacecraft returned, komarov died due to parachute failure. These were major accidents in manned space flight.
to further investigate people's ability to live and work in space environment for a long time, and to use the unique space environment to conduct research and applied experiments in a variety of disciplines, such as biology, medicine, astronomy, material and process experiments, earth resource survey and military activities, etc. at the same time, to accumulate experience for the establishment of practical space stations. Participating in this phase of activities are space stations for astronauts to live and work for a long time, manned spacecraft to transport astronauts and return to earth, and cargo spacecraft to supply fuel for the space stations and necessities of life for astronauts, such as the Soviet union's "progress" cargo ship.

Keep in mind that the Suhosin patch which is installed by default on many
PHP-installs such as Debian and DirectAdmin completely disables the srand and
mt_srand functions for encryption security reasons. To generate reproducible
random numbers from a fixed seed on a Suhosin-hardened server you will need to
include your own pseudorandom generator code.
===============================================================================
To generate a random number which is different every day, I used the number of
days after unix epoch as a seed:
My provider upgraded the php server recently, and calling srand(seed) does not
seem to set the seed anymore. To let srand set the seed, add the following line
to your .htaccess file
php_value suhosin.srand.ignore 0
Kudos to doc_z (http://www.webmasterworld.com/php/3777515.htm)

srand() is pretty tricky to get right. You should never seed a random number
generator more than once per php process, if you do, your randomness is limited
to the source of your seed.
The microtime function's micro-seconds portion has a very finite resolution,
that is why the make_seed function was added to the document. You should never
get the same seed twice.
In the later CVS versions, PHP will seed the random generator prior to
performing a rand() if srand() was not previously called.
===============================================================================
It is REALLY essential to make sure that srand is called only once.
This is a bit difficult if the call is hidden somewhere in third-party code you
include. For example, I used a standard banner script that *seemed* to work
well putting
three random banners in one frame. But in the long run, the choice appeared
somewhat biased - probably because srand was called once per banner, not
once per run.
It would be nice if the random number generator worked like in PERL: If You use
the random function without having called srand ever before in a script,
srand is invoked before (and automatically with a nice seed, hopefully).
I suggest that one should do something like this:
(Depending on the situation, one might also work with a static variable
instead)
===============================================================================
Sorry about that... ok, forget have of what I said up there ^.
The code that would prove my example is this:
Each time you SHOULD get the same answer, but if you did this:
then the answers would be different, and you'd be letting the random number
formula do it's duty.
===============================================================================
OK, to summarize what people have been saying so far:
1. DO NOT seed the RNG more than once if you can help it!
2. You HAVE TO seed the RNG yourself if you are using PHP < 4.2.0.
3. Using a prime multiplier to microtime() probably does very little. Use the
Mersenne Twister instead.
4. You can use the Mersenne Twister PRNG with the mt_rand and mt_srand
functions. This is faster and is more random.
===============================================================================
srand and mt_srand are both initialized only once per process ID.
You cannot re-seed your rand algorithms after the first "srand", "mt_srand",
"rand", "mt_rand", "shuffle", or any other rand-like function.
I have been facing an issue where after forking my process, all childs were
generating exactly the same rand values.
This was due a first "shuffle" call on the parent process, so I could not
re-seed the childs.
To solve my issue, I simple called "rand" N times, to offset the child rand
generators.
# Offset the child rand generator by its PID
$n = (getmypid() % 100) * (10 * abs(microtime(true) - time()));
for ($n; $n > 0; $n--) {
rand(0, $n);
}
Since each pcntl_fork takes a while to be completed, the microtime offers an
extra offset, other than one PID increment.
This small code will make at the WORST hypothesis 1000 iterations.
===============================================================================
I have a ramdon circulater that changes a piece of text once a day, and I use
the following code to make sure the see is unique enough.
$tm = time();
$today = mktime(0, 0, 0, (int)date("n", $tm), (int)date("j", $tm), (int)date
("Y", $tm));
srand($today / pi());
The pi works wonders for the whole thing and it works like a charm. Any other
big decimal number will do as well, but pi is the most common "big" number.
===============================================================================
Another use of srand is to obtain the same value of rand in a determined time
interval. Example: you have an array of 100 elements and you need to obtain a
random item every day but not to change in the 24h period (just imagine
"Today's Photo" or similar).
You obtain the same value every time you load the page all the 24h period.
===============================================================================
I simply use this, and it has always worked fine:
function initRand ()
{
static $randCalled = FALSE;
if (!$randCalled)
{
srand((double) microtime() * 1000000);
$randCalled = TRUE;
}
}
function randNum ($low, $high)
{
initRand();
$rNum = rand($low, $high);
return $rNum;
}
===============================================================================
In addition to my earlier post being stupidly coded with $wasseeded = TRUE :-|
here is an update:
In PHP4, I *BELIEVE* the random number generator will seed itself if you don't
seed it.
In PHP3, or some versions of PHP3?, that was not the case -- An unseeded rand()
wouldn't be random.
While it would "work fine" in terms of spitting out a number, an unseeded
random number generator won't be very random in many situations unless it has
been properly seeded.
I'm afraid I can't explain all the details of why this is because A) it would
be an entire textbook, and B) I don't know them all by heart, even if I
understood them 20 years ago in college.
If you are running PHP4, you are probably okay, and if you are happy with the
randomness of your values, you are fine, but you may want to do a little test
like:
\n";
}
$stats[$choice]++;
}
reset($stats);
while (list($num, $count) = each($stats)){
echo "$num: $count
\n";
}
?>
Run the test a half-dozen times and check that the distribution of 1, 2, and 3
is even, and that the first number chosen is not the same every time.
This is hardly an exhaustive test, but it at least gives some reassurance that
the numbers aren't completely predictable.
You may also wish to switch to http://php.net/mt_rand which is faster (if you
generate a *LOT* of numbers) and allegedly a "better" (more random) function.
Again, it would be an entire book to explain why mt_rand is "more random"...
YMMV. If you're doing "Casino Slots" with real money, you'd better do your
homework on this. If you're giving away a free CD or something silly, who
cares?
===============================================================================
The make_seed() function in the example code is VERY bad, and is in fact
responsible for seeding always the same value, so that the output of rand() is
the same with every page reload (!)
ALWAYS use:
(double)microtime()*1000000
See for more details my note on the mt_srand() page [ function.mt_srand.php ]
===============================================================================
How about
srand((double)microtime()*1000000);
$seed = rand(1000000,9999999);
srand((double)microtime()*$seed);
$yadda = rand (1,100);
?>
I used this in a test run with 1,000.000 calls for $yadda. Processing time
increased by 0.0000061 seconds compared to a simple "srand((double)microtime()
*1000000);"
$yadda had the value of each number between 1 and 100 for between 0.99999122%
and 1.00000872% of all calls. That's random and fast enough for me. :)
===============================================================================
As a sidenote on the usage of srand():
If you are making use of modular programming, it is probably better to try and
call the srand routine from the parent script than from any modules you may be
using (using REQUIRE or INCLUDE).
This way you get around the possibility of calling srand() more than once from
different modules.
The flaw in this solution, of course, is when using modules produced by another
programmer, or when producing modules for another programmer.
You cannot rely on another programmer calling the srand function before calling
the modular function, so you would have to include the srand function inside
the module in this case.
If you produce modules for use by other programmers then it is good practice to
documentise the fact you have already called the srand function.
Or if you use a modular function produced by someone else, check their
documentation, or check their source code.
===============================================================================
Use the srand() seed "(double)microtime()*1000000" as mentioned by the
<EMAIL_ADDRESS>at the top of these user notes.
The most notable effect of using any other seed is that your random numbers
tend to follow the same, or very similar, sequences each time the script is
invoked.
Take note of the following script:
If you seed the generator with a constant, say; the number 5 ($val = 5), then
the sequence generated is always the same, in this case (0, 18, 7, 15, 17) (for
me at least, different processors/processor speeds/operating systems/OS
releases/PHP releases/webserver software may generate different sequences).
If you seed the generator with time(), then the sequence is more random, but
invokations that are very close together will have similar outputs.
As<EMAIL_ADDRESS>above suggests, the best seed to use is (double) microtime
() * 1000000, as this gives the greatest amount of psuedo-randomness. In fact,
it is random enough to suit most users.
In a test program of 100000 random numbers between 1 and 20, the results were
fairly balanced, giving an average of 5000 results per number, give or take
100. The deviation in each case varied with each invokation.
===============================================================================
Calling srand((double)microtime()*1000000),
then $a=rand(1000000,9999999), then srand((double)microtime()*$a)
adds nothing to the entrophy: the execution time of rand and srand is
constant, so the second microtime() produces nothing really fascinating. You
may safely use just the first srand().
===============================================================================
I can’t stress how important it is to seed your randomisation process in code!
better still something we found in the BBS Days was if we didn’t seed from a
token from outside our systems abstraction layer we would go in circles and so
would our users. Here at chronolabs we offer a feed of randomly changing token
on each impression, it also randomly displays a different number of them this
is from http://seed.feeds.labs.coop in the example below I use DOM to load the
XML, Extract the randomisation tokens and then with mt_srand and srand seed the
random selecting processes! The following function when you call it will seed
your random selection process in both the old and new random selection routines
all you need to do is call the function! This will work with any version of PHP
5 and any earlier with DOM Objectivity.
function makeRandomSeeded() {
$file = 'http://seed.feeds.labs.coop/';
$doc = new DOMDocument();
$doc->loadHTMLFile($file);
$skip = array('This feed can', 'Current mode is');
$elements = $doc->getElementsByTagName('description');
foreach($elements as $element) {
$seed = $element->nodeValue;
$found = false;
foreach($skip as $find) {
if (substr($seed, 0, strlen($find))==$find) {
$found = true;
}
}
if ($found==false)
$seeds[] = $seed;
}
shuffle($seeds);
mt_srand($seeds[mt_rand(0, count($seeds)-1)]);
srand($seeds[mt_rand(0, count($seeds)-1)]);
}
Remember when PHP says an integer this also include any character of the Ascii
chart if you would like to see an example of this do the following:
===============================================================================
Something we discovered in Sydney running BBS Systems before the net advent was
here, if we didn't seed of another BBS we would going in circles in our System
Physicality Abstraction Layers.. The important thing is to seed from a remote
system and easy way at the Centroidal Plexus of the web (Chronolabs
Cooperative) we offer a seed feed and the following code will randomise you out
of the number cycle:
See in PHP both the letters and numbers are seedable as letters are treated as
numbers as well. You can always use individual tokens by extracting the Element
with DOM.. But below is equally effective!

A drone for every pocket
Affordable variants are flooding the market thanks to high demand
by Tharun BodaVIJAYAWADAWith a strong demand for drones from commercial photographers, prices have come down vastly in the past few years. Major drone manufacturers have introduced smaller variants of their bestselling models for affordable prices. Now, one can buy a drone with basic camera equipment for just about ₹12,000. The smallest professional drones available in the market weigh about 300 grams and can fly up to a height of 50 metres from ground level.Depending on the features of the camera and the flying capacity, prices can go into lakhs. The Energy Department is reportedly planning to engage drones which cost a whopping ₹50 lakh to monitor high-tension power lines across the State. The high-capacity drones are capable of flying to a distance of up to 8 km. This helps authorities check the condition of equipment on the HT towers which are mostly located in isolated areas and agriculture fields, which are sometimes inaccessible by road.


Game Purpose: This game is meant to be an interactive platform where users can learn about how climate change impacts polar bears in a simple and accessible
way. Polar bears depend on sea ice to survive; sea ice serves as their hunting ground. With the sea ice melting, polar
bears are struggling to survive and are on the path to extinction. By creating this game, we hope to make it easier for people to learn about how global
warming is changing the Arctic and threatening the survival of polar bears.
