Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

 I had been involved with getting lagochilus earlier than this experience, and consumed the herbal product a year or so ago. I had been ripped off a substantial amount of money initially by an inept Albanian doctor who sent me kilos of the wrong material. So I was very eager to push the envelope of dosage of the reputed desired psychoactive component, lagochilin.
It was around 11pm after work. I had taken some daily opiate dosages earlier that evening, and a few hits of cannabis a few hours prior, but being a regular user I was pretty much baseline. I am perticularly interested in diterpene pharmacology, and thus so far have rounded up several plant species that contain active diterpene compounds, one is even a kappa opioid agonist, and a beta endorphin type agonist. looking at the reports of usage and effect available on lagochilus I considered that diterpenes similiar in structure found in lagochilin might perhaps be a gabba, benzo, or opioid agonist in nature of effect. So after work I vaporized 20 some milligrams of this lagochilin in a clean glass ginseng bottle, the material harsh, and raspy but not too bad tasting. Mildly floral, the scent was noticeable I think in the smoke of the whole plant.
What I considered might be a mild effect seemed to creep over me, a mild stimulating feeling, clarity of mind, but nothing strong. So I layed out 3 20 some milligram piles of the material and insuffilated roughly 20 milligrams. The material burned ever so slightly, and seemed to dissolve and saturate very quickly. After waiting 5 minutes, and sitting in a relaxed mode in my basement study, I finished the last 40 some milligrams.
10 minutes later I find myself feeling pretty good, comfortable, and mildly stimulated, the amount of plant material in my nose was about gone, and I noticed a general feeling of well-being. As the night went on, around 1 pm I started nodding off at the computer, which is NOT a normal thing for me to do, even when taking my moderate daily dosage of a pound of poppy seeds, 150 milligrams of tramadol, and a 3rd of a gram of 50% alkaloid kratom extract throughout the day. I sat and nodded and scanned the internet in a very relaxed and interested state until sleep got the better of me, and I woke up at 3:30 am and went to bed.
I felt no hangover in the morning, like higher dosages of opiates will do to me, and no hangover like taking large amounts of gaba might. I will try higher dosages probably. I am very glad to have had the experience of searching out an unknown and finally getting the chance to experience the material. I have moved my main interest on to other plants that are very rare or non existant for all I know in the united states, mostly opioid in nature, and some with real 'potential'. I think lagochilus should be taken up as a possible medicinal herb, it has already been profiled by the American Botanical Council as such, seems like ethical harvesting and supply/price is all that is holding back lagochilus as a herbal supplement.

Reminder! To run these examples, you should first start a new session then load the sample database using:"/localvision/samples/general/sample.load" asFileContents evaluate ;Any other files referenced can be read from the /localvision/samples/general/ directory.Note: The sample.load file runs by default on a Unix environment. If you are using a Windows NT platform, this location may be prefixed by a drive and optional path (e.g. d:/visiondb/localvision/samples/general/sample.load). Check with your Vision Administrator for further details.
Type the expression:
3Submit the request to Vision. You should see
3displayed as the result.
Now type:
1.23You will see:
1.23displayed. In fact, if you submit any number - positive, negative, integer, or decimal - Vision will respond by redisplaying the number you requested in the Output Window. Vision can accomplish this feat with strings as well. A string is any combination of characters enclosed in double quotes.
For example, type:
"This is a string"and submit this request. You will see:
This is a stringdisplayed. Vision can do more than merely redisplay whatever you submit. For example, type:
22 + 5The answer, 27, will be displayed. Try this with strings. For example, type:
"This is a string" + 5You should see:
>>> Selector '+' Not Found <<< NAdisplayed. What does this response mean and why was it only displayed after you tried to add 5 to a string? When you submit the request 22 + 5, you are asking Vision to perform the addition operation between two numbers, 22 and 5. Since this is a defined operation, Vision complies with your request by performing the calculation and displaying the result. When you ask Vision to add 5 to a string, Vision complains because the addition operation is not defined for strings. The Selector Not Found response identifies the specific operation that Vision could not perform. In this case, the operation is ;
Now try this experiment. Submit the request:
"This is a string" countYou should see:
16The count operation is defined to count the number of characters in a string. The answer indicates that the supplied string contains 16 characters.
Submit:
3 count
You should see
> Selector 'count' Not Found <<< NAIf you ask Vision to perform the operation count for a string, Vision complies by counting the number of characters in the string. When you ask Vision to perform the count operation on a number, Vision complains because this operation is not defined for numbers. In this case, the Selector Not Found response specifically identifies that count is the operation that could not be performed.
Now submit:
"This is a string" count + 3You should see:
19.00Although you cannot add 3 to a string, you can add 3 to the number of characters in the string. In this case, Vision counts that there are 16 characters in the supplied string, adds 3 to this number, and displays the result of 19.
This may be a good time to step back and explore what is really happening inside Vision. The basic unit of information in Vision is known as an Object. For example, the number 3, the string "This is a string", GM's common stock, and a list of companies are all objects in Vision. As you have seen in the above examples, different operations are defined for different types of objects. Arithmetic operations such as + are meaningful with numbers but not with strings. The count operation is meaningful with strings but not with numbers.
Similar kinds of objects are organized into Classes. For example 3, 17, and 1.75 are all part of the class Number and "a", "This is a string", and "3" are all part of the class String. Objects in a class are referred to as Instances of that class. For example, 3 is an instance of the class Number. Objects in a class all respond to a set of operations defined for that class. In the Vision language, operations are known as Messages. A request for an object to carry out one of its operations is known as Sending A Message. All the instances in a class respond to the same set of messages.
In the example:
"This is a string" count + 3the message count is sent to the string "This is a string" and the number 16 is returned. The message + 3 is then automatically sent to the number 16, producing the result 19. In the example:
3 countthe message count is sent to the number 3. Since the class Number has no definition for the message count, the Selector 'count' Not Found response is displayed.
All objects in Vision repond to a set of messages. All objects respond to the message displayMessages by displaying the list of messages defined for object. For example, type:
3 displayMessagesYour should see the messages that are valid to send to the number 3. The list of messages is expanded over time. The displayMessages message will always provide an up-to-date list.
All objects in the system have a default way in which they print. For example, integers are right justified in a 9 character field and print with no decimal places and decimal numbers are right justified in a 9 character field and print with 2 decimal places. Strings are left justified when they are printed.
When you submit a request, Vision automatically sends the message print to the final result. In other words, when you submit the request:
3Vision actually evaluates the expression:
3 printand therefore prints the value 3 when it is done. Try submitting the request:
3 printYou will see the result:
3 3The 3 is printed twice. The first 3 is the one you explicitly requested; the second is Vision automatically sending the print message to the result. Both versions are printed in 9 character positions; 8 blanks followed by the number.
You can alter the format of the result. For instance, suppose you wanted to print the number 1.1 to 3 decimals places. Submit the expression:
1.1 print: 8.3You will see the result:
1.100 1.10The first value is the result of the print: message. The second value is again the result of Vision's automatic print feature. To suppress this second value, place a semi-colon at the end of your input line as shown below:
1.1 print: 8.3 ;You will see the result:
1.100The print format of 8.3 indicates that you wanted your result printed in 8 character positions with 3 decimal places to the right of the decimal. The total character width of 8 includes the space required for the decimal point and digits.
Many other formatting tools are available for printing. A few simple messages are described below.
To print the number 5 million with commas, type the following:
5000000 printWithCommas: 12 ;You should see:
5,000,000To start a new line after the value is printed use the printNL or printNL: message. For example, type:
3 printNLYou should see:
3 3The second 3 is the result of Vision's automatic print message. It appears on a separate line because the printNL message automatically prints a carriage return after the first 3. In both cases, the number is printed with 9 characters.
To left justify a number, send it the print: message with a negative value for the parameter. For example, the expression:
3 printNL: -9displays the output:
3######## (where # indicates a blank space) ########3The first 3 is left justified in 9 character positions. The second 3 is the result of Vision's automatic print message which right justifies the value in 9 character positions. It appears on a separate line because the printNL: message automatically prints a carriage return after the first 3.
By default, all characters in a string are printed. No truncation or padding occurs. The print: message can be used to control the output width of a string. The value after the : indicates the number of characters that should be output. Strings containing fewer characters than the supplied width are padded with the appropriate number of blanks on the right (i.e., they are left-justified) by default. A String containing more characters than the supplied width will have its rightmost characters truncated.
For example, the expression:
"xyz" print: 2 ;displays
xyand the expression:
"xyz" print: 10 ;displays the output:
xyz####### (where # indicates a blank space)To right justify a string, send it the print: message with a negative value for the parameter. For example, the expression:
"x" print: -20 ;Produces the output:
#19 spaces xThe message center: can be sent to a string to center it over a specified number of columns. For example to center a title over the 80 columns type:
"My Title" center: 80You should see:
My TitleThe message centerNL: works in the same way as center:, but follows the output by a carriage return.
The print: message differs from the standard print message in one important way; it has a parameter.  In the case of the print: message, the parameter provides information regarding the column width and number of decimal places to use when printing the value. In the example:
1.1 print: 8.3 ;the parameter 8.3 indicates that the result should occupy 8 character positions and that the result should be rounded to 3 decimal places.
Try omitting this parameter as shown below:
3 print:You should see the response:
>> 'syntax error' near source line 1, character 11 <<< 3 print: ** ^Since Vision was expecting a value following the print: message and none was provided, you are informed that you have made a syntax error. Vision tries to identify where the error occurred and provides an indicator arrow (i.e., the ^ symbol) in the area where the problem was first identified. In this case, the arrow points to the area directly after the print: message.
You have actually already seen another example that uses a parameter. The message + requires that you provide an additional piece of information, namely a number that you wish to add to the original number. Try leaving off this parameter as shown below:
3 +You should see:
>> 'syntax error' near source line 1, character 4 <<< 3 + ** ^As you can see, the error message is the same as in the prior example.
Whether you realize it or not, you have already written your first Vision program. A program is merely a set of one or more Vision requests. All the programs you have seen so far have asked Vision to perform a single request. There are situations where you would like to perform a set of operations, one after another. Vision provides a simple mechanism for accomplishing this.
For example, submit the following:
"The Answer Is: " print ; 2 + 2You should see:
The Answer Is: 4.00The semi-colon is used to separate expressions within a Vision program. Each expression is executed in sequence. Vision automatically sends the print message to the result of the last expression. If you terminate the last expression with a semi-colon, the automatic printing is suppressed.
A block is a special form of program that represents a deferred sequence of steps. The general form for a block is illustrated below:
[ statement 1 ; statement 2 ; . . . ]Blocks always return the value of the last statement executed. Blocks are often used as parameters to other messages. For example, the ifTrue:ifFalse: message requires two parameters that are blocks that contain the program to run if a specific condition is (is not) met. For example:
myList count > 100 ifTrue: [ "This is a big list." print; ] ifFalse: [ "This is a small list." print; ];If the number of elements in the list myList is greater than 100 the program supplied by the first block is executed. In this case the string "This is a big list" will be displayed. Otherwise, the program supplied by the second block is executed. In this case the string "This is a small list" will be displayed.
It is often useful to save the results of specific tasks for later use. For example, type in the following program:
!x <- 2 + 2The answer 4 should appear. Now type:
x + 1You should see the answer 5.
The results of any Vision expression can be saved into a Variable. You can create as many variables as you need during the course of your session. Any information that you save into a variable is available for the remainder of your session or until you redefine the variable.
To create a variable, type ! followed by a valid variable name. The <- message is used to assign a value into this variable. For example, enter the following program:
!x <- 2 ; !y <- 3 ; !z <- x + y ; "The Value Of x is: " print; x printNL; "The Value Of y is: " print ; y printNL ; "The Value of x + y (z) is: " print; z printNL ;Your should see:
The Value Of x is: 2 The Value Of y is: 3Variables can be used to store values other than numbers. For example, create a variable called answer containing the string: "The Answer Is:" as illustrated below:
The Value of x + y (z) is: 5.00
!answer <- "The Answer Is: "Now try the following program:
answer print; 2 + 2You should see:
The Answer Is: 4.00

Since the Digital Chroma is a computer, it's not generally a good idea to turn it off by yanking the power. This can, in rare cases, lead to corruption of the files that store your {_program programs}. Instead, press the power switch firmly for a second. The display will say "Shutting down\.", and the instrument will turn off after a second or so. Then, it is safe to unplug the unit if you need to pack it up and move it.
If the unit ever crashes (not that that is likely to happen), you can force the power to shut off by holding the power switch for five seconds. Then, after waiting a few seconds, you can press the power switch again to restart the instrument.


Panther Test Kata Exercises
Welcome to the Panther Test Kata exercise - this page will give you a breakdown of tasks for throughout the workshop.
Setting up your machine
First off you will need a laptop, and a power cable (we'll be working on it most of the day) which has either Firefox or Chrome as a browser installed, ideally both!
The exercises requires a machine which can run Java - don't worry too much if you're relatively new to Java, the exercises are designed to be useable with a minimum understanding of the language (although you'll get more out of it the more you understand).
To help, you'll also be working in groups.
Still, it's important to arrive with a working laptop that's ready to go!
Here are software items I need you to pre-install,
- Oracle Java Development Kit (JDK) relevant for your machine. This will allow Java to run on your machine. This is required for your Integrated Development Environment to work on. Currently can be found here.
- IntelliJ IDEA Community Edition (IDE). This is where we'll be editing code. Currently can be found here.
- GitHub Desktop. This will make pulling down the code examples so much easier. I suggest creating a GitHub account (it's free).
It's also worth cloning the following repositories to your machine,
- pantheraircraftodminitial
- pantheraircraftodmmodified
- pantheraircraftseleniumbasic
- pantheraircraftseleniumautomation
I recommend a Windows laptop, but the code work on Linux, and should also worin on a macOS (however I've not been able to check the macOS).
If possible, I recommend pre-reading through the following introduction to the scenario you face together with this set of requirements.
You will also need to download the following repositories from GitHub, and open them in IntelliJ Community Edition.
- pantheraircraftodminitial
- pantheraircraftodmmodified
- pantheraircraftseleniumbasic
- pantheraircraftseleniumautomation
When you open them in IntelliJ, you need to select to auto import to bring through any dependencies. You might also need to set an appropriate version of Java to run on - this is the Project SDK which can be accessed under Project Structure,
Exercise 1 - Testing fuel data load
We start working with pantheraircraftodminitial from GitHub.
This is the start version of the code we're working on.
We are going to focus on the tests in src/test/java/testsheepnz/panther/odm/calculator/test/FuelRateDataTests.java
These tests are designed to test the how the class FuelRateData copes with lines of data given.
Currently there is a postive and negative test created, but the test manager doesn't like them. Can you do better?
Exercise 2 - Testing equipment load
We start working again with pantheraircraftodminitial from GitHub.
We are going to look at the other test class which can be found in src/test/java/testsheepnz/panther/odm/calculator/test/AircraftManagementTests.java
- What are your thoughts on these tests?
- What are they trying to test?
- Do any of the scenarios look familiar?
During this exercise you'll create a series of tests to check for scenarios with equipment loads. Think what makes a good test, and what will make for useful feedback.
Report any issues you find with the software. If you're feeling really confident, you might want to have a go at fixing them.
Exercise 3 - Fuel Rate Data
We start working again with pantheraircraftodminitial from GitHub.
There are a number of tables of fuel rate data in the ODM requirements.
On paper - you need to design a number of scenarios to test this data. Just follow the maths! You might find the following aid helpful.
Later on in this exercise you will be asked to check out pantheraircraftodmmodified from GitHub.
Exercise 4 - UI Tests With Selenium
We will now be working with pantheraircraftseleniumbasic from GitHub.
A working version of the software has been built with a front-end. It can be found here.

Build and run a few basic tests. Work with the initial tests in /src/test/java/testsheepnz/panther/aircraft/test/EquipmentFormTest.java
Exercise 5 - What went wrong?
We will now be working with pantheraircraftseleniumautomation from GitHub.
This repository contains a lot more defined tests.
A number of builds can be found here. Builds 1-5 have been rejected, but no-one knows the exact reason why.
You can get this suite to run on the builds by going into the file test.properties and editing the command website_under_test to point to the appropriate html link.
You can read through any errors, but also check out logs in /src/main/resources/screenshots. You can also check out manually if you need to.

Exercise 6 - Refuel fun
This item is extension material - to be honest we could run another full day on this code base! Different people are at different stages in their automation journey, so some might want to tackle this on the day or else look at later.
New functionality has been added for refueling on this page.
You need to create a new page definition class for this under https://github.com/TestSheepNZ/pantheraircraftseleniumautomation/tree/master/src/main/java/testsheepnz/panther/page
It might help to look at items like the ClimbPage.java or DivePage.java which have similar definitions.
You need to think not just about the elements you need to define but also any methods for what you'll want to do with the elements.
Finally you will want to define a test class under /src/test/java/testsheepnz/panther/aircraft/test/ which includes some tests.
Again, you might want to look at ClimbTest.java and DiveTest.java for starting ideas.
As in the previous exercise, before running you need to go into the file test.properties and edit the command website_under_test to point to the appropriate html link.
Exercise 7 - Redefine using XPath (BONUS)
This is an item for you to try after the workshop - support can be provided remotely.
Currently if you look at the classes under src/main/testsheepnz.panther/page all the @FindBy instances are find by ID,
@FindBy(id = INITIAL_FUEL_FIELD)
private WebElement fuelField;
Change the code, starting with EquipmentPage.java to work from find by XPath. Make sure you keep running your test to make sure what you're changing still works!
Harnessing the power of Google, look to see how you find XPath elements for a page, and what advantages there are against find by ID.
Exercise 8 - Browser support (BONUS)
This is an item for you to try after the workshop - support can be provided remotely.
You are going to attempt to support Internet Explorer (IE) as a supported browser going forward. This obviously only works for Windows machine, if you have another machine, just choose another browser for which you can find driver support.
1) Download driver
Download the driver for Internet Explorer and place in the resources/drivers.windows folders.
2) Handle case for IE browser
Browser support is provided by setting the value browser in test.properties and how this parameter is handled in TestProperties.java including the enum BrowserType and method setBrowserType.
3) Open WebDriver for IE instance
If you look into the method launchDriver for class SeleniumInstance, you will find a set of if statements covering opening the WebDriver instance for different browsers.
You need to create a new instance to handle IE browsers, including handling the name of the driver and where it is located.
4) Troubleshoot
IE is one of the trickiest browsers to work with and doesn't work as 'out of the box' as other browsers. You will need to investigate this - but you'll need to set some InternetExplorerOptions before setting driver.
You can find a lot of help about other drivers on the Selenium downloads page here.


What we do?
We help students get the help they need by interacting with staff by just creating a ticket.
We focus on supporting and improving the experience of getting help while on Lambda.
It allows students to submit a help desk ticket, categorize it and post it to the help channel.


Nnamdi Azikwe
The man fought for Nigeria Independence
- 1904 - Dr Nnamdi Azikwe was born
- 1934 - Dr Nnamdi Azikwe became candidate for a doctoral degree at Columbia University before returning to Nigeria.His doctoral research focused on Liberia in world politics, and his research paper was published by A. H. Stockwell
- 1941 - Dr Nnamdi Azikwe became active in the Nigerian Youth Movement (NYM), the country's first nationalist organization. Although he supported Samuel Akinsanya as the NYM candidate for a vacant seat in the Legislative Council in 1941, the NYM executive council selected Ernest Ikoli. Azikiwe resigned from the NYM, accusing the majority Yoruba leadership of discriminating against the Ijebu-Yoruba members and Ibos
- 1945 - As a result of Azikiwe's support for a general strike in June of this year and his attacks on the colonial government, His publication of the West African Pilot was suspended on 8 July of this year. He praised the striking workers and their leader, Michael Imoudu, accusing the colonial government of exploiting the working class.
- 1950 - Under the Richards constitution, Azikiwe was elected to the Legislative Council in a Lagos municipal election from the National Democratic Party (an NCNC subsidiary). He and the party representative did not attend the first session of the council, and agitation for changes to the Richards constitution led to the Macpherson constitution.
- 1960 - Dr Nnamdi Azikwe Azikiwe became the first governor-general with Abubakar Tafawa Balewa as prime minister and also became the first Nigerian named to the Privy Council of the United Kingdom.
- 1963 - Dr Nnamdi Azikwe became the first president of Nigeria,When Nigeria became a republic in 1963, Azikiwe's role was largely ceremonial.
- 1996 - Dr Nnamdi Azikwe died at the University of Nigeria Teaching Hospital in Enugu after a long illness, and is buried in his native Onitsha
There is plenty of room at the top because very few people care to travel beyond the average route. And so most of us seem satisfied to remain within the confines of mediocrity.

Hi all,
This should be a simple question for the Experts, I guess.
The Arduino sketch (Discrete Sampling) uses the calcVI function, which samples voltage and current during 20 voltage crossings, i.e. 10 waveforms, so for a total of 200ms.
There's no frequency specified, meaning the Arduino just loops as fast as it can. According to the Arduino doc, it takes 0.1ms to read an analog pin. In each loop in EmonLib, we read voltage and current, so an iteration should take 0.2ms.
This means there should be about 1000 samples in a while loop. But browsing the forum, people say it gets only 500 samples in that time.
What accounts for the difference? Is it the calculation time in the loop (i.e. the rest of the code besides the "analogRead" instructions)?
Thanks!
Re: Number of samples in the calcVI function
Basically - yes. The loop has to apply the high pass filter, the phasecal algorithm and accumulate the squared values of voltage and current for the rms calculations and the power for the real power average. If you look at the filter,
filteredV = 0.996*(lastFilteredV+(sampleV-lastSampleV));
you might think that the brackets around "(sampleV-lastSampleV)" are redundant, but in fact they force the subtraction to be done first and that happens in fixed point arithmetic, then the rest of the calculation is done in floating point. Those brackets mean an integer subtraction instead of a floating point one and one less conversion to a float, and hence another two or three sample pairs per cycle.
The loop can be speeded up if you perform the calculations using fixed point arithmetic rather than floating point, but the fixed point calculations are a lot harder to understand and follow through.
Re: Number of samples in the calcVI function
When the ADC is free-running, my Mk2i PV Router code does approx 96 pairs of V & I samples per mains cycle. The quoted period for a single conversion is 104 us, so that value looks spot on. By use of integer maths, the main processor is only around 70% occupied.
Re: Number of samples in the calcVI function
Ok thanks for your answers Robert and Calypso. I was actually trying to solve a sub-problem in my 3-phase measurement sketch. Robert made the point that if you want to shift voltage phase by X degrees, you need to know how many samples in a cycle you have, and probably interpolate between 2 samples.
My idea was, if I know the # of samples in a cycle programmatically, I can do a dynamic calculation and determine between which 2 samples to interpolate.
But what I take from this discussion is:
1) I can't tell the number of samples from the code itself. But could by empirical measure when the system is running.
2) The number shouldn't change very much across iterations, but I suspect if I want to make this really stable I should avoid IF statements so that the code is more deterministic.
Does this make sense?
Re: Number of samples in the calcVI function
What you have to remember is, unless you have a highly reactive load and a correspondingly poor power factor, the actual phase shift you apply is not all that critical, because the curve is flat-topped.
Why are you worrying about IF statements? What branches are there in the main body of the main loop - while it is reading the 10 cycles and getting the numbers on which to base the calculations? I can't see any.
The other variables that you might not have thought about are the variation of mains frequency (1% is allowed either side of the nominal for us in the UK), and clock drift in your crystal. Both will affect the timing and hence introduce what looks like a phase error. And you can do nothing about that. Unless...
If you really want to avoid the problem altogether, you should be looking at MartinR's PLL sketch, adjust it so that it locks to 3n samples per cycle (say 48) and then (if phase 1 is the 0th) the second and third phases of a 4-wire system will be EXACTLY the 16th and 32nd samples in the array, and for your 2-phase 3-wire system the second phase will be the 8th sample; and they will stay there even if the frequency changes.
[For anyone who does not know the history, Amaury has a 3-wire 3-phase system, 230 V L-L and no neutral wire; and the loads are connected in delta. He is measuring two phases with respect to the third, so he has in effect a 2-phase system with 60° between the phases.]
There are a number of users of the sketch (on 4-wire) and they seem to have had no problem with setting it up empirically by following the instructions in the comments.

THE ARRIVAL A film review by Scott Renshaw Copyright 1996 Scott Renshaw
(Orion) Starring: Charlie Sheen, Lindsay Crouse, Ron Silver, Teri Polo, Tony T. Johnson. Screenplay: David Twohy. Producers: Thomas Smith, Jim Steele. Director: David Twohy. Reviewed by Scott Renshaw.
These are the times that try a critic's soul, these summer months of high budgets and low expectations. They are the times that can make me begin to question what it is I am looking for in escapist entertainment, as I read raves for hyped-up disappointments like TWISTER and MISSION: IMPOSSIBLE and wonder what it is that I am supposed to be missing. They are the times when a piece of fluff like DRAGONHEART seems that much better when compared to the competition, and they are the times when a film like THE ARRIVAL, lacking a big star or never-before-seen special effects, will likely drown in a sea of higher-profile releases. But THE ARRIVAL is the kind of thriller which reminds me _exactly_ what I'm looking for in escapist entertainment: a script which has genuine wit, genuine intelligence, and genuine excitement, and which convinces me that the writer spent at least as much time creating it as I spent watching it. That perfectly describes THE ARRIVAL.
Charlie Sheen stars as Zane Ziminski, a radio astronomer working at a Search for Extra-Terrestrial Intelligence (SETI) facility, searching the skies for signals of other-worldly origin. On one late-night shift, that is exactly what he finds, yet Zane's boss Phil Gordian (Ron Silver) seems remarkably cool to the news, and in fact informs Zane that he is being laid off. But Zane refuses to let go of his discovery, and his continuing investigation leads him to Mexico. There he hooks up with Ilana Green (Lindsay Crouse), an atmospheric researcher studying global warming. Together, they begin to discover a conspiracy which suggests that the aliens aren't just coming -- they're already here.
THE ARRIVAL marks the directing debut of writer David Twohy (THE FUGITIVE and the under-appreciated TERMINAL VELOCITY), and he demonstrates such a keen understanding of what makes an action thriller work that it seems he was born for the job. In the first minute of the film, he grabbed me by the collar with a beautifully constructed opening sequence, and for the next 109 minutes he simply refused to let go. There are sequences in THE ARRIVAL which play like textbook examples of how to build tension, particularly one involving a room full of scorpions which is guaranteed to have you squirming if you have a pulse. There is a kind of suspense which plots based on paranoia are much better at generating, and Twohy nails it, as well as turning it to humorous effect by connecting the greenhouse effect and the failure of the Hubble telescope to alien visitors.
That is really what separates THE ARRIVAL from the pack: a sense of humor which surpasses most of the so-called comedies I see in any given year. Sheen has a solid, deadpan sense of comic timing which worked well with Twohy's TERMINAL VELOCITY script, and again he wraps each line in a wry self-awareness. Zane is not a particularly dynamic role -- he's gung-ho about finding extra-terrestrial life, but it's never quite clear why -- and another actor might have given it more depth. However, Sheen makes the comic lines feel un-scripted, and he appears to be adept at playing Twohy's favored hero -- a resourceful individual whose actions under duress seem natural and basically intelligent. Plus, there is a priceless irony to Sheen, the most notorious and unapologetic customer of "Hollywood Madam" Heidi Fleiss, reading the line, "There's something to be said for abstinence."
THE ARRIVAL is so effective in some of its early scenes that the big sequence in the aliens' lair comes as something of a disappointment, since Twohy seems less concerned with maintaining the pace than he is with showing off his visual effects. There are a few logical errors I caught upon reflection, and the abrupt ending is likely to leave some viewers feeling a bit unsatisfied. But THE ARRIVAL is a rarity so far this summer movie season: it is a smart and tightly-plotted film that I couldn't always out-guess, and didn't always find myself _trying_ to out-guess. I was so instantly aware of how skillfully David Twohy could manipulate me that I simply let him. And that, friends, is how I define "willing suspension of disbelief."
On the Renshaw scale of 0 to 10 illegal aliens: 8.

o help us understand her; she is merely presenting us with the facts of an individual's life and the world surrounding that individual. I SHOT ANDY WARHOL is exceedingly well-documented, and that makes it great journalism. Mary Harron directs her actors and her environment to perfection, and that makes it great theater. What is missing is human drama, and a sense of what this story is really about. That, quite simply, does not make a great film.
On the Renshaw scale of 0 to 10 shots in the dark: 7.

New packages published to npm after 1st December 2021 should use a scoped name, they may then use any value in their package name eg @devname/acme-node-red
Packages first published before this date can use unscoped names, however when the package name starts with node-red
(or nodered
then it MUST use node-red-contrib
The following names would be allowed:
node-red-contrib-acme
nodered-contrib-acme
acme-nodered
The following would not be allowed:
node-red-acme
nodered-acme
Initially the contrib formatting was used to distinguish 3rd party nodes from core nodes created by the project. As the number of nodes has grown the namespace has become more cluttered, a move to scoped names will allow for cleaner naming of nodes by service providers. Scoped names also allow for a developer to fork an abandoned node and publish a new version with the same pacakge name but within their scope. This makes it clearer to users where multiple packages exist.

Health deteriorates of DU student on hunger strike
by Staff ReporterA Delhi University student sitting on a hunger strike to protest against the construction of a 39-storey building in North Campus said on Friday that he had been advised by doctors to end the protest or risk deteriorating his health. His has been on a strike since November 10.
The student claimed that tests had shown that he was suffering from jaundice and an eye infection. The students said the building would breach the privacy of students living in women’s hostels.
The students said the land on which the building is coming up belonged to the Ministry of Defence and was meant for “public use”. It was reportedly transferred to the DMRC, which gave it to a private builder. The protesters have demanded that the Defence Ministry intervene and give approval to transfer the property to DU.


Pope takes his anti-nuclear campaign to Japan
by Philip Pullella and Kay JohnsonBangkok: Pope Francis left Thailand on Saturday after a three-day visit and headed to Japan, where he is to visit the ground zeros of Hiroshima and Nagasaki as part of his campaign against nuclear weapons.
The pope, 82, was accompanied to the airport by his cousin, Sister Ana Rosa Sivori, a nun who has worked in Thai schools for more than 50 years and was his translator on the trip.
He is expected to turn his focus to his anti-nuclear campaign, particularly on Sunday, when he visits Hiroshima and Nagasaki, the world's only two cities to suffer nuclear attacks.
About 400,000 people were killed, either instantly or from radiation illness or injuries resulting from the atomic bombs that the United States dropped on Hiroshima on August 6, 1945 and on Nagasaki three days later, as it sought to end World War II.
Francis will meet blast survivors, pray, and read a message on nuclear weapons at the bomb epicentre in Nagasaki. He later visits Peace Memorial Park in Hiroshima.
In the Japanese capital, he will meet survivors of the 2011 Fukushima nuclear disaster.
Francis, who, as a young priest, wanted to be a missionary in Japan, will also meet some of a dwindling number of its "Hidden Christians", descendants of those who preserved their faith in secret during centuries of persecution until a ban on Christianity was lifted in 1873.
He wants a total ban on nuclear weapons, going further than his predecessors, when he said in 2017 that countries should not stockpile them, even for the purpose of deterrence.
Japan stresses its unique status as the only nation to have suffered atomic attacks and advocates disarmament, but nonetheless relies on the US nuclear umbrella as an extended deterrent.
Japan is mainly Buddhist and Shinto and only about 1 per cent of its population of about 126 million identify as Christian. Of this number, some 536,000 are Catholic.
Christians are disproportionately present among Japan’s elite, some of whom may have also attended Christian private schools without adopting the religion.
Two Japanese prime ministers have been Catholics: Takashi Hara, from 1918 to 1921, and current finance minister Taro Aso, who was prime minister during 2008-2009.
In Thailand, the Pope celebrated Mass with the small Catholic minority in an overwhelmingly Buddhist country, and spoke out against human trafficking and sexual exploitation of women.

WWV Simulator
This site attempts to simulate the audio portion of stations WWV and WWVH. It should sound much like what you’d hear if you tuned in a shortwave radio to one of these stations. Each station has its own style of tones and voice time announcements. Station identification is every half hour.
This is only an simulation, using your computer’s time and samples of the audio. It is not a rebroadcast of the real stations.
What is WWV?
WWV is a radio station run by the National Institute of Standards and Technology (NIST) that broadcasts precise time and frequency from Fort Collins, CO. A companion station, WWVH, provides a similar service from Kekaha, HI. The time sources are highly accurate atomic clocks. These broadcasts contain an audible portion (which this site emulates), and a digital time code that can be received by clocks and watches for automatically maintaining precise time.
WWV has operated continuously since 1919, but in 2019 its future was in doubt due to proposed budget cuts that could have shuttered the stations. Fortunately the final NIST budget preserved the funding.
Why make this site?
I have fond memories of WWV being one of the first stations I picked up when I got my ham radio license many years ago. It was one of the few stations that could nearly always be picked up on some frequency, even during poor propagation. When conditions were good, sometimes I could also hear WWVH (Hawaii → Chicago is a bit of haul). Besides just tuning it in, I actually liked having it on while doing my homework! The steady pulses, curious patterns of tones, and old-timey timbre of the occasional voice announcements made for nice background noise.
WWV has never (to my knowledge) been streamed over the internet. There are many sample recordings available, but nothing that just runs and reflects the current time. Creating a simulated WWV website has been on my “someday” project list for a long time, but the threat of WWV/H being shut down provided serious motivation to make it a reality. Even if NIST does power down the amplifiers, this site can still provide a reasonable representation of what those iconic stations sounded like.
How Accurate is It?
Time-wise, this site is exactly as (in)accurate as your computer or phone clock currently is. As far as how well it matches the real WWV/H transmissions, my goal has been to mimic the audio portion as closely as reasonably possible. The stations have distinct patterns of pulses, tones, and voice announcements which have been implemented. The simulation includes all of the elements except for real-time voice announcements, such as space weather reports, and some really esoteric things like special adjustments for leap seconds. If you find an error, let me know!
Note: if you’re listening with bluetooth headphones, the pulses and clock might be slightly out of sync. Furthermore, if the browser doesn't have focus or the tab isn’t active, timing can become skewed (browser dependent).
Implementation
The voice announcements were obtained from the telephone time service that NIST provides. This laborious process involved recording and editing hundreds of calls. Calls were made with Google Hangouts, and all editing was done in Audacity. A small program was written to generate the tones and pulses according to the NIST specification. The voice samples and generated tones are then interleaved according to the current time and broadcast schedule of the selected station. In November 2022, the identification samples were updated with higher quality radio recordings.
The application itself is entirely in Javascript. It leans heavily on the Howler and Driftless libraries to accurately sequence the audio clips.
Donations
Some fans of this site have asked about how they can show their support, buy me a coffee, etc. I finally got around to setting up a donation link, and any contributions are appreciated. Thank you!

Two dead, one missing after rainstorms drench south France
Marseille: Two people lost their lives and one more was missing Sunday after historic levels of rain drenched the south of France, provoking major floods that are only now starting to recede, officials said.
One corpse was found in the village of Muy, just north of France's Mediterranean coast, close to where a rescue dinghy had capsized on Saturday evening with three members of the fire brigade and three civilians aboard, the local authorities in the southern Var region said.
One of the civilians had been reported missing.
The second body, of a man in his 50s, was found in the village of Cabasse in a car, said the local authorities, without giving further details.
Meanwhile, another man, in his 70s, was still missing in the village of Saint-Antonin-du-Var after going out during the night amid heavy rain. Searches are continuing.
The Alpes-Maritimes and Var regions have since Friday been hit by torrential rainstorms that also caused huge waves in seaside areas.
The senior official for the Var region, Jean-Luc Videlaine, told AFP that the rains had been of "historic" intensity, adding that the damage will be "considerable".
He said that water levels were now going down but added that the situation was "far from returning to normal".
In some areas of the Var region, the equivalent of two or three months of rain fell in just 24 or 48 hours.

Vectors Vector Addition Dot Product Cross Product Line-Point Distance Polygon Area Introduction Many TopCoders seem to be mortally afraid of geometry problems. I think it's safe to say that the majority of them would be in favor of a ban on TopCoder geometry problems. However, geometry is a very important part of most graphics programs, especially computer games, and geometry problems are here to stay. In this article, I'll try to take a bit of the edge off of them, and introduce some concepts that should make geometry problems a little less frightening. Vectors Vectors are the basis of a lot of methods for solving geometry problems. Formally, a vector is defined by a direction and a magnitude. In the case of two-dimension geometry, a vector can be represented as pair of numbers, x and y, which gives both a direction and a magnitude. For example, the line segment from (1,3) to (5,1) can be represented by the vector (4,-2). It's important to understand, however, that the vector defines only the direction and magnitude of the segment in this case, and does not define the starting or ending locations of the vector. Vector Addition There are a number of mathematical operations that can be performed on vectors. The simplest of these is addition: you can add two vectors together and the result is a new vector. If you have two vectors (x1, y1) and (x2, y2), then the sum of the two vectors is simply (x1+x2, y1+y2). The image below shows the sum of four vectors. Note that it doesn't matter which order you add them up in - just like regular addition. Throughout these articles, we will use plus and minus signs to denote vector addition and subtraction, where each is simply the piecewise addition or subtraction of the components of the vector. Dot Product The addition of vectors is relatively intuitive; a couple of less obvious vector operations are dot and cross products. The dot product of two vectors is simply the sum of the products of the corresponding elements. For example, the dot product of (x1, y1) and (x2, y2) is x1*x2 + y1*y2. Note that this is not a vector, but is simply a single number (called a scalar). The reason this is useful is that the dot product, A ⋅ B = |A||B|Cos(θ), where θ is the angle between the A and B. |A| is called the norm of the vector, and in a 2-D geometry problem is simply the length of the vector, sqrt(x2+y2). Therefore, we can calculate Cos(θ) = (A ⋅ B)/(|A||B|). By using the acos function, we can then find θ. It is useful to recall that Cos(90) = 0 and Cos(0) = 1, as this tells you that a dot product of 0 indicates two perpendicular lines, and that the dot product is greatest when the lines are parallel. A final note about dot products is that they are not limited to 2-D geometry. We can take dot products of vectors with any number of elements, and the above equality still holds. Cross Product An even more useful operation is the cross product. The cross product of two 2-D vectors is x1*y2 - y1*x2 Technically, the cross product is actually a vector, and has the magnitude given above, and is directed in the +z direction. Since we're only working with 2-D geometry for now, we'll ignore this fact, and use it like a scalar. Similar to the dot product, A x B = |A||B|Sin(θ). However, θ has a slightly different meaning in this case: |θ| is the angle between the two vectors, but θ is negative or positive based on the right-hand rule. In 2-D geometry this means that if A is less than 180 degrees clockwise from B, the value is positive. Another useful fact related to the cross product is that the absolute value of |A||B|Sin(θ) is equal to the area of the parallelogram with two of its sides formed by A and B. Furthermore, the triangle formed by A, B and the red line in the diagram has half of the area of the parallelogram, so we can calculate its area from the cross product also. Line-Point Distance Finding the distance from a point to a line is something that comes up often in geometry problems. Lets say that you are given 3 points, A, B, and C, and you want to find the distance from the point C to the line defined by A and B (recall that a line extends infinitely in either direction). The first step is to find the two vectors from A to B (AB) and from A to C (AC). Now, take the cross product AB x AC, and divide by |AB|. This gives you the distance (denoted by the red line) as (AB x AC)/|AB|. The reason this works comes from some basic high school level geometry. The area of a triangle is found as base*height/2. Now, the area of the triangle formed by A, B and C is given by (AB x AC)/2. The base of the triangle is formed by AB, and the height of the triangle is the distance from the line to C. Therefore, what we have done is to find twice the area of the triangle using the cross product, and then divided by the length of the base. As always with cross products, the value may be negative, in which case the distance is the absolute value. Things get a little bit trickier if we want to find the distance from a line segment to a point. In this case, the nearest point might be one of the endpoints of the segment, rather than the closest point on the line. In the diagram above, for example, the closest point to C on the line defined by A and B is not on the segment AB, so the point closest to C is B. While there are a few different ways to check for this special case, one way is to apply the dot product. First, check to see if the nearest point on the line AB is beyond B (as in the example above) by taking AB ⋅ BC. If this value is greater than 0, it means that the angle between AB and BC is between -90 and 90, exclusive, and therefore the nearest point on the segment AB will be B. Similarly, if BA ⋅ AC is greater than 0, the nearest point is A. If both dot products are negative, then the nearest point to C is somewhere along the segment. (There is another way to do this, which I'll discuss here). //Compute the dot product AB ⋅ BC int dot(int[] A, int[] B, int[] C){ AB = new int[2]; BC = new int[2]; AB[0] = B[0]-A[0]; AB[1] = B[1]-A[1]; BC[0] = C[0]-B[0]; BC[1] = C[1]-B[1]; int dot = AB[0] * BC[0] + AB[1] * BC[1]; return dot; } //Compute the cross product AB x AC int cross(int[] A, int[] B, int[] C){ AB = new int[2]; AC = new int[2]; AB[0] = B[0]-A[0]; AB[1] = B[1]-A[1]; AC[0] = C[0]-A[0]; AC[1] = C[1]-A[1]; int cross = AB[0] * AC[1] - AB[1] * AC[0]; return cross; } //Compute the distance from A to B double distance(int[] A, int[] B){ int d1 = A[0] - B[0]; int d2 = A[1] - B[1]; return sqrt(d1*d1+d2*d2); } //Compute the distance from AB to C //if isSegment is true, AB is a segment, not a line. double linePointDist(int[] A, int[] B, int[] C, boolean isSegment){ double dist = cross(A,B,C) / distance(A,B); if(isSegment){ int dot1 = dot(A,B,C); if(dot1 > 0)return distance(B,C); int dot2 = dot(B,A,C); if(dot2 > 0)return distance(A,C); } return abs(dist); }That probably seems like a lot of code, but lets see the same thing with a point class and some operator overloading in C++ or C#. The * operator is the dot product, while ^ is cross product, while + and - do what you would expect. //Compute the distance from AB to C //if isSegment is true, AB is a segment, not a line. double linePointDist(point A, point B, point C, bool isSegment){ double dist = ((B-A)^(C-A)) / sqrt((B-A)*(B-A)); if(isSegment){ int dot1 = (C-B)*(B-A); if(dot1 > 0)return sqrt((B-C)*(B-C)); int dot2 = (C-A)*(A-B); if(dot2 > 0)return sqrt((A-C)*(A-C)); } return abs(dist); }Operator overloading is beyond the scope of this article, but I suggest that you look up how to do it if you are a C# or C++ coder, and write your own 2-D point class with some handy operator overloading. It will make a lot of geometry problems a lot simpler. Polygon Area Another common task is to find the area of a polygon, given the points around its perimeter. Consider the non-convex polygon below, with 5 points. To find its area we are going to start by triangulating it. That is, we are going to divide it up into a number of triangles. In this polygon, the triangles are ABC, ACD, and ADE. But wait, you protest, not all of those triangles are part of the polygon! We are going to take advantage of the signed area given by the cross product, which will make everything work out nicely. First, we'll take the cross product of AB x AC to find the area of ABC. This will give us a negative value, because of the way in which A, B and C are oriented. However, we're still going to add this to our sum, as a negative number. Similarly, we will take the cross product AC x AD to find the area of triangle ACD, and we will again get a negative number. Finally, we will take the cross product AD x AE and since these three points are oriented in the opposite direction, we will get a positive number. Adding these three numbers (two negatives and a positive) we will end up with a negative number, so will take the absolute value, and that will be area of the polygon. The reason this works is that the positive and negative number cancel each other out by exactly the right amount. The area of ABC and ACD ended up contributing positively to the final area, while the area of ADE contributed negatively. Looking at the original polygon, it is obvious that the area of the polygon is the area of ABCD (which is the same as ABC + ABD) minus the area of ADE. One final note, if the total area we end up with is negative, it means that the points in the polygon were given to us in clockwise order. Now, just to make this a little more concrete, lets write a little bit of code to find the area of a polygon, given the coordinates as a 2-D array, p. int area = 0; int N = lengthof(p); //We will triangulate the polygon //into triangles with points p[0],p[i],p[i+1] for(int i = 1; i+1<N; i++){ int x1 = p[i][0] - p[0][0]; int y1 = p[i][1] - p[0][1]; int x2 = p[i+1][0] - p[0][0]; int y2 = p[i+1][1] - p[0][1]; int cross = x1*y2 - x2*y1; area += cross; } return abs(cross/2.0);Notice that if the coordinates are all integers, then the final area of the polygon is one half of an integer. ...continue to Section 2

@nielsen_schreier : Π {α : Type} (H : set (free_group α)) [is_subgroup H], ∃ (R : Type), nonempty (H ≃* free_group R) ∧ nonempty (quotient H × α ⊕ unit ≃ quotient H ⊕ R)
A while ago I decided to try to prove the Nielsen-Schreier theorem on free groups to get more familiar with Lean. Now, after countless days of self-isolation, I have a working proof. Comments welcome!
Is there any advantage in using parameters over variables?
non-terminal simp
s are discouraged in general, because they can cause trouble with maintenance. There are workarounds (e.g. run simp
and then see what the goal has become, and try something like suffices : <new goal>, from simpa using this
)
We are in the process of moving to bundled subgroups rather than is_subgroup
@David Wärn Nice work! At a first glance, a lot of the stuff there looks quite well done.
It would be really nice to have this in mathlib
But like you say, you might want to factor out some parts
Unfortunately we don't have any graph theory yet...
I think it would be nice to have a predicate that asserts that a group is freely generated by a subset of its type, so that we can quantify over subsets of H here instead of arbitrary types
Great job!
Kevin Buzzard said:

I think I chose parameters to try to convey the meaning of keeping things fixed, but variables might be better (at least it would let me use some lemmas for the two different free groups that occur in the argument)
Mario Carneiro said:

That would be nice. You'd just need to prove that an isomorphism with a free group gives a freely generating subset
Johan Commelin said:

I'll think about making this mathlib-friendly. Would it be worth it to create a small graph theory section with the proof of existence of spanning trees? The characterisation of spanning trees I used is somewhat non-standard: Basically I think of it as a rooted tree where I can do recursion along the edges.
I think we should stop complaining that there are many possible ways to formalize graphs and trees. We should go ahead, put them in mathlib, and we'll refactor (or add parallel implementations) if needed.
There are many possible ways to formalise algebra stuff -- there are groups, rings, fields etc and we just formalised all of them and proved the links between them. "Graphs" feel the same to me -- it is a catch-all word which can mean many things, and they should all be in.
it's only when they're in that we start realising how we should have done it.
@David Wärn why don't you start by just making a basic graph API and PR'ing it? This is how I started. I wrote a basic complex numbers API and PR'ed it, and I think that by the end of the process none of the lines of code I had originally written were left.
Just make the stuff you need for your proof.

ABOUTME ABOUTME ABOUTME ABOUTME ABOUTME I am experienced in leveraging agile frameworks to provide a robust synopsis for high level overviews. Iterative approaches to corporate strategy foster collaborative thinking to further the overall value proposition.
Hackathons are a 24-hour project where people are divided into teams and try to accomplish an idea using resources provided by the organisers.
➢ I have learned how to work in teams with people I have never met.
➢ I worked on projects using Arduino and software provided by Microsoft Azure.
➢ I came up with an idea during OxfordHack to use Image recognition software provided by Azure to search for a car's number plates using street cameras in case of crime. I used C++ to write this program and we had some help from mentors provided. Although we did not win as it was very challenging, our project was recognized by organisers.
➢ I Designed a Website with my team from scratch as a project for my High shcool.
➢ I Used HTML and CSS to make our website.
➢ Leadership : I was assigned as the leader of my team, so I had to delegate tasks according to everyone's expertise. I faced some challenges as a leader where some people could not do their work properly so I had to assign their work to someone else or do it myself.
➢ Management : I used Milestones for management; where I divided tasks into smaller ones and then made a deadline for every task according to its significance and complexity.
A team and I made a self-balancing robot as a project for kids to know more about engineering and how exciting it was to be an engineer.
➢ I was responsible for the software part of the project where I had to make a PID controller using an Arduino.
➢ It was challenging to tune the PID controller, however I overcame this by doing as much research as possible and reading other people's code and understanding it to modify it to our robot's specifications as our robot had different dimensions and mass.
➢ Although everyone had his own tasks, I managed to apply knowledge sharing between us so that we can learn from each other's work and integrate our work together.
I was inclusions officer in the Egyptian society.
➢ We won the Cultural/National society award that year.
➢ People always thought that Egyptian society is merely for Egyptians and that's not true, So I had to change that by making sure that our events are diverse as possible and that they include everyone.
➢ I developed communication skills as it was my responsibility to talk to members about their experience and preferences. Also, we had a weekly meeting to discuss new events.
Programming a PIC microcontroller in C to get the robot to follow a black line (University Project)
➢ I used SparkFun infra-red sensors to detect a black line.
➢ I used soldering to connect the electronic components with the microcontroller.
The university provided us with soldering equipment in labs and I managed to design the circuit and solder it
to the circuit board.
➢ I used the concept of feedback control systems in programming for the robot to follow the
black line. There were 8 sensors on the front of the robot. I managed to program the robot to
keep the black line between el 4th and the 5th sensor so that the black line is at the centre of the
robot. As the black line make any turns, the robot must follow. I managed to achieve that by
calculating error which is distance between centre of the robot and the black line and then
change robot's direction towards black line and multiply original speed of motor by error to
increase the robot speed. As the robot goes further away from the line, robot's speed must
increase in the opposite direction.
I Designed a tensile test machine on Fusion 360 (University assignment)
➢ I managed to sketch parts from scratch and put threads in, then join body parts together.
Link to CAD
Worked with a team of five on a simulation of Automated mosquito surveillance and disease
prediction service.
➢ Presentation: I had to do a presentation with my team in front of 50 people presenting our idea
and receiving feedback afterwards.
➢ Leadership: Led our team and tried to make sure everyone has a task and a deadline to
complete it so that we would be right on schedule.
I have participated in volunteer work with Resala Charity Organization to spread food among poor and
homeless people in Egypt
➢ Team work: worked with a team to spread as much food as possible.

accordingly.
➢ I learned that helping people is the most rewarding thing that someone could do.
TV show competiton between schools in many different subjects (General knowledge).
➢ I and seven other students were chosen by my school to represent it in the competition.

This realm type allows you to configure Web applications to authenticate users against it.
Enter the name of security realm and select Properties File Realm from the Realm type: menu. Click Next and follow the wizard.
When you create a new properties file realm through the administrative console, the key values you supply are in the configuration options field, which is the location and filenames of the user and group property files, for example:
usersURI=var/security/vhost1_users.properties
groupsURI=var/security/vhost1_groups.properties
By default, the security realm used by the server to authenticate administrative users for console and deployer access, is the geronimo-admin properties file realm.
The following example illustrates a deployment plan for this default geronimo-admin realm.
Once the security realm has been created, you can click the usage link to view samples of how to apply the new realm in your applications.
