### How much of the emulator do I need to implement?
As little as possible to get a particular LS-8 program running.
Add features incrementally. Once print8.ls8
is working, then add a MULT
instruction to get mult.ls8
running. And so on.
Of course, you’re allowed to implement as many instructions are you’d like.
This goes for individual components like registers, as well. Do you need to implement the FL
register? If you want to use any functionality that depends on it, then yes. The spec will tell you if the thing you’re implementing needs the FL
register to work.
### Once we get the HLT
instruction, what should the emulator do?
You should exit the emulator.
You don’t need to worry about any of the LS-8 internals at that point since you’re exiting anyway.
### How do you return values from subroutines?
Since the RET
instruction doesn’t allow you to specify a return value, you’ll have to get the value back by other means.
One of the most common is to set a register (e.g. R0
) to the return value, and the caller will just know, by convention, that the R0
register will hold that value once the CALL
returns.
But you could also push that value on the stack and have the caller pop it off. This would have the advantage of supporting an arbitrary number of return values.
There are no fixed rules when writing code in assembly language. Returning values in registers just happens to be a common convention.
### With interrupts, why do we push everything on the stack?
The idea is that if you save the machine state on the stack, then after you service the interrupt you can restore it and seamlessly pick up where you left off.
The CPU might have been in the middle of something important when the interrupt occurred, and it’ll want to get back to that once the interrupt handler is complete.
So we push the general purpose registers and internal registers on the stack, then do interrupt stuff, then restore all those registers from the stack so the CPU can carry on with what it was doing before the interrupt occurred.
Short answer: it’s when the stack grows into some area of memory that something else was using.
In the LS-8, this would mean the stack grew down in RAM to the point that it overwrote some of the instructions in the program.
If the stack grows down to address 0x00
on the LS-8, it wraps around to address 0xff
.
On modern machines with virtual memory, this isn’t a practical concern since you’ll run out of physical RAM before the stack overflow occurs.
Some interpreted languages like Python track how large their internal stacks have grown and crash out if the stack grows too large. But this is happening within the Python virtual machine, not on the hardware.
### What is “stack underflow”?

The CPU is more than happy to let you do this, but it’s considered an error on the part of the programmer.
If the stack pointer is at address 0xff
on the LS-8, then you POP
, it will wrap around to address 0x00
.
### On the LS-8, why does the stack pointer start at address F4
, when the first stack element is at F3
?
Since the first thing a PUSH
instruction does is decrement the stack pointer, it means that the stack pointer is moved to F3
first and then the value is stored there. Exactly where we wanted it.
### How are stacks and subroutines used by higher-level languages like Python?
In Python, when you make a function call, a bunch of space is allocated (pushed) on the stack to hold a number of things:
This allocated chunk of stack is called a stack frame.
When you call any function:
When you return from any function:
In assembly language, CALL
doesn’t allow any arguments to be passed, and RET
doesn’t allow any values to be returned.
Using stack frames gives CALL
the power to give parameters to subtroutines.
And we can use a dedicated register, like R0
, to pass returned values back to the caller over a RET
instruction.
Since all the local variables for a function are stored in the stack frame, they all vaporize as soon as the stack is popped when the function returned. This is why local variables are not persistent from call to call.
Furthermore, using the stack to hold frames allows us to call functions to an arbitrary nesting level. Indeed, it is what allows for recursion at all.
### Is the flags FL
register one of the Rx
registers, or is it a special register?
It’s a special purpose register that can be added separately to the class CPU
similar to how PC
works.
In class CPU
, it’s convenient to have an array to store R0
through R7
, but the other registers are just fields in the class
.
### What about the IR
, MAR
, and MDR
registers?
You can store those special-purpose registers similar to how PC
and FL
are stored in the class
.
…Or, if you’re not using them in any place except a single function, maybe they can be locals or function parameters.
It’s a matter of which way you think produces more readable code.
### What are the registers for, and what do they do?
You can think of the registers as the CPU’s variables. They hold numbers. You use them like you would variable in another langauge.
In a high-level language, you can make all the variables you need. But in a CPU, there are a fixed number of them, and they have fixed names, and they only hold numbers. You cannot make more.
(The reason you can’t make more is because registers are literally built out of the hardware–you can’t make more without changing the hardware.)
Most operations (like math) in the CPU work on registers.
But if we have RAM, why do we need registers?
While some CPUs like the x86 can use either values in RAM or registers to do work, RAM is far, far slower to access. Nothing is faster to access in the CPU than a register. For that reason, assembly language programs use registers whenever possible to keep speed up.
### If RAM is faster than an SSD, why not just store everything in RAM?
Cost. 1 TB SSD is orders of magnitude cheaper than 1 TB of RAM. And finding a motherboard that supports 1 TB of RAM is a challenge.
Also the SSD continues to store data even if power is removed, unlike RAM.
Someday someone will discover RAM that is cheap, fast, and will permanently store data, and when that happens, SSDs will vanish.
### Do CPUs get hot because of the power constantly running through them?
Yup. When you run current through any regular conductor, heat is generated.
In that regard, a CPU is like a tiny, expensive electric blanket that is capable of arbitrary computation but really bad at giving you a good night’s sleep.
### Why is hex base 16? Seems so random.
Conveniently, one hex digit represents exactly 4 bits (AKA a nibble).
This means a byte can be represented by exactly 2 hex digits (assuming you put a leading zero on numbers less than 0x10
). And the biggest byte’s value roundly ends at 0xff
.
It’s compact, and easy to convert to and from binary.
Compare to decimal, where one decimal digit represents somewhere between 3 and 4 bits. And a byte is represented by 3 digits, isn’t easily convertible to binary, and ends quite unroundly on 255
for the largest value.
### How do I move the PC
to the next instruction without hardcoding the instruction length?
Check out the spec where it talks about instruction layout.
The two high bits of the instruction tell you how many operands the instruction has. The value of those two bits plus one is the number of bytes you have to move the PC
.
Use >>
and an &
mask to extract those two bits, then add one to the result, then add that to the PC
to get to the next instruction.
Note that some instructions (like
CALL
,RET
, and all theJMP
variants) move thePC
to a specific destination. In those cases, you do not want to advance the PC to the next instruction.
### Why are the ALU and the RAM read/write functions broken out? Can we just code the lines to do the work directly?
Because the ALU is a separate component on the CPU, and the RAM is a separate component off the CPU, it makes logical sense from a learning perspective to have different pieces of code handle the work.
Plus having the RAM access function there makes the code easier to read, and easier to change if the structure of RAM were to change somehow in the future.
### Do you have some handy code for helping trace what the CPU is doing?
You’ll find a trace()
function in cpu.py
that you can call each iteration of your main loop to get a dump of registers, etc.
### Why is R7
set to something other than zero?
R7
has additional meaning: it is the stack pointer. So it needs to start just past the top of the stack so that the PUSH
and POP
(and CALL
and RET
) functions operate normally.
### Why do opcodes have the numeric values that they do?
See the “Instruction Layout” part of the LS-8 spec for what the specific bits mean in any particular instruction.
In a real CPU, these bits correspond to wires that will have voltage or no-voltage on them depending on whether or not the bit in the instruction is 0
or 1
.
So the instruction bits are close to the metal, literally. Their exact meanings are closely tied with how the CPU will be physically constructed.
### What is a “cache hit” or “cache miss”?
If a program accesses a byte of RAM at some address that’s in the cache already, that’s a cache hit. The byte is returned immediately.
If a program accesses a byte of RAM at some address that’s not in the cache, that’s a cache miss, and the cache must be updated by going out to RAM to get that data.
The cache is fast memory that sits between main RAM and the CPU.
It’s common that if you access a byte of RAM, that you will soon access subsequent bytes in RAM. (E.g. like when printing a string, or doing a strlen()
.) The cache makes use of this assumption.
The cache figures, if you’re going to spend the time making a relatively slow RAM request for a single byte, why not go ahead and transfer the next, say 128 bytes at the same time into the faster cache. If the user then goes on to access the subsequent bytes, like they probably will, the data will already be in cache ready to use.
### How are logic gates built?
They’re made out of transistors. Details are getting into the realm of materials science and is beyond the scope of the course.
### How does the CPU use logic gates?
Logic gates can be composed into circuits that can do far more than Boolean logical operations.
You can build an ALU, for example, that does arithmetic and comparisons using only logic gates.
You can even build circuits that store data.
The fantastic book The Elements of Computing Systems talks about this in great detail from the ground up.
### Why is half a byte called a nibble?
It’s a pun, playing off byte/bite. Sometimes it’s spelled nybble.
### What are the <<
and >>
shift operators useful for?
Most commonly, they’re used to get or set individual bits within a number.
This is useful if multiple values are packed into a single byte. Bytes hold numbers from 0 to 255, but parts of a byte can hold smaller numbers. For example, if you have 4 values that you know only go from 0-3 each, you can pack that into a byte as four 2-bit numbers.
Packing the numbers 3, 0, 2, and 1 into a single byte:
Three
||
|| Two
vv vv
0b11001001
^^ ^^
|| One
||
Zero
This technique is normally only used in high-performance situations where you absolutely must save space or bandwidth.
For example, if we wanted to extract these 3 bits from this number:
vvv
0b10110101
We’d get 110
, which is 6 decimal. But the whole number is 181 decimal. How to extract the 6?
First, we can shift right by 3:
vvv
0b00010110
Then we can bitwise-AND with the mask 0b111
to filter out just the bits we want:
vvv
0b00010110 <-- Right-shifted original number
& 0b00000111 <-- AND mask
------------
110
And there’s our 6!
On the flip side, what if we wanted to set these bits to the value 2 (0b010
)? Right now the three bits have the value 7 (0b111
):
vvv
0b10111101
First let’s take our 2:
0b010
and left shift it by 3:
0b010000
Secondly, let’s use a bitwise-AND on the original number to mask out those bits and set them all to zero:
vvv
0b10111101 <-- original number
& 0b11000111 <-- AND mask
------------
0b10000101
^^^
These three bits set to 0, others unchanged
Lastly, let’s bitwise-OR the shifted value with the result from the previous step:
vvv
0b10000101 <-- masked-out original number from previous step
| 0b00010000 <-- our left-shifted 2
------------
0b10010101
^^^
Now these three bits set to 2, others unchanged
And there we have it. The three bits in the middle of the number have been changed from the value 7 to the value 2.
### What is the difference between general-purpose registers and internal, special-purpose registers?
The general-purpose registers are R0
through R7
.
Special-purpose registers are things like PC
, FL
, and maybe IR
, MAR
, and MDR
.
The main difference is this: general-purpose registers can be used directly by instructions. Special-purpose registers cannot.
LDI R0,4 ; Valid
LDI PC,5 ; INVALID--PC is not a general-purpose register
ADD R0,R1 ; Valid
ADD FL,R0 ; INVALID--FL is not a general-purpose register
In class CPU
, it’s convenient to represent the general purpose registers with an array for easy indexing from 0
to 7
.
### Why does the CPU allow for stack overflow or underflow?
It takes time for the CPU to check to see if either condition has occurred. And most of the time it won’t have.
CPUs are interested in running instructions as quickly as possible.
Also, you’d need additional hardware in place to make those checks, and that costs money.
Because assemnbly language is so low-level, the CPU is already putting basically ultimate trust in the developer to not do something they shouldn’t do.
If you didn’t want me to overflow the stack, why did you tell me to overflow the stack?
–The CPU
### Why does the CPU support a stack and not some other data structure?
Turns out a stack is a really useful data structure for a number of reasons:
Additionally, it’s pretty cheap to implement. All CPUs already come with this functionality:
Since the CPU was doing all that anyway, adding PUSH
and POP
instructions is a pretty low-hanging fruit.
### On a multicore CPU, is there some kind of overseer that coordinates between the cores?
Not really, and from a programmer perspective, no.
Cores have their own registers, own PCs, and generally run autonomously on their own.
What they do share is RAM (and usually at least some cache) and peripherals.
The real “overseer” is the operating system, which decides which programs run on which core at any particular time.
### On a multicore CPU, do cores share registers or do they have their own sets?
They have their own.
Cores generally run autonomously on their own.
What they do share is RAM (and usually at least some cache) and peripherals.
### Are the flags on the LS-8 stored on the stack or in a register?
Flags (the FL
register) are their own special-purpose register, similar to the PC
.
Each bit of the FL
register has special meaning as laid out in the LS-8 spec.
### Does the ALU handle conditionals/CMP
?
Yes.
The compare instruction CMP
will set the flags register appropriately indicating whether or not the values of the registers compared are less-than, greater-than, or equal.
This is actually quite similar to a subtraction, which the ALU can already do.
If I give you two numbers, a
and b
, and you compute the difference b - a
, you can look at the result and determine if the values are equal, or if one is greater than the other.
If b - a
is a positive number, it means that a
is less than b
.
If b - a
is a negative number, it means that a
is greater than b
.
If b - a
is zero, it means that a
equals b
.
So the ALU can use its subtraction circuitry to do a CMP
, saving money and construction complexity.
### On the LS-8, why does POP
need an operand?
Because you probably want to know what the value was you popped off the stack, rather than just throwing it away.
Basically, POP R0
is saying “pop the value from the top of the stack and store it in R0
.”
### How are floating point numbers represented in binary?
There is a standard binary format for storing floating point numbers called IEEE 754.
It basically breaks a number into three parts:
A simpler-to-comprehend example might be in base 10, decimal.
For example, the components that make up the decimal number -98.273
are:
-1
(because it’s -98, not 98)
98273
(all the digits)
-3
(tells us where the decimal place is)
The result (again for base 10) is:
sign * mantissa * 10 ^ exponent
or:
-1 * 98273 * 10 ^ -3 == -98.273
Basically the exponent tells us how to left (if it’s negative) or right (if it’s positive) to shift the decimal point.
It works exactly the same way in binary (base 2):
The components that make up the binary number 0b101.11
are:
0b1
(because it’s 101, not -101)
0b10111
(all the digits)
-2
(tells us where the decimal place is)
Then the formula is:
sign * mantissa * 2 ^ exponent
or:
0b1 * 0b10111 * 2 ^ -2
Again, the exponent tells us how far to shift the decimal; in this case, shift it 2 bits left for 0b101.11
.
Printing out binary floating point numbers in decimal is a bit weird because you have to think in fractions of two instead of 10.
Decimal example:
12.34
is written as:
1
10s (10 == 101)
2
1s (1 == 100)
3
1/10ths (1/10 == 10-1)
4
1/100ths (1/100 = 10-2)
Of course you see powers of 10 all over because it’s base 10.
With base two, binary:
11.01
is written as:
1
2s (2 == 21)
1
1s (1 == 20)
0
1/2s (1/2 == 2-1)
1
1/4s (1/4 == 2-2)
Which would give us (in decimal): 2 + 1 + 1/4
or 3.25
.
11.01
binary is 3.25
decimal.
Luckily printf()
handles that with %f
for us.
### How are signed integers represented in binary?
It’s a format known as two’s complement.
Basically, about half of the bit patterns are used for negative numbers.
The following is an example with 3-bit integers, though it applies equally well to integers of any number of bits.
Unsigned, binary on the left, decimal on the right:
111 7
110 6
101 5
100 4
010 2
011 3
001 1
000 0
Signed (same on the right, but in sorted numeric order):
111 -1 010 2
110 -2 011 3
101 -3 001 1
100 -4 000 0
011 3 111 -1
010 2 110 -2
001 1 101 -3
000 0 100 -4
Notice how the bit pattern for 7
(unsigned) is 111
, which is the same bit pattern for -1
(signed).
So is 111
-1
or is it 7
? It depends only on whether or not you are looking at those bits as signed or unsigned.
Another thing to notice is that if the high (leftmost) bit of a signed number is 1
, it means that number is negative.
Also notice how the positive signed numbers have the same bit patterns as their unsigned counterparts.
If you have a signed number (either sign) and you want to find it’s two’s complement opposite, first you subtract one from it and then take the bitwise-NOT of that result.
2
is 0b010
binary.
1
to get 0b001
.
0b110
.
0b110
is -2
.
Using two’s complement to represent signed numbers has one great advantage: the exact same circuitry in the ALU can be used to add or subtract numbers regardless of whether they are signed or unsigned. The ALU doesn’t have to care.
### How does the CPU cache work? What is L1, L2, L3 and so on?
You don’t have to implement any kind of emulated cache on the LS-8.
Generally speaking, the cache is some fast memory that’s closer to the CPU than RAM.
The assumption is that if a program wants a byte at address x
, it’s likely to very soon thereafter want the byte at address x + 1
.
(Imagine printing a string, for example. You got the first byte, printed it, and now you’re going to print the next one.)
So CPU first looks in the cache to see if the byte is there. If it’s not, it goes out and requests a block of memory from RAM be copied into the cache. The block includes the byte in question, but also the subsequent bytes.
Then when you go to read the subsequent bytes, they’re in the super fast cache and you don’t have to go to RAM again, thus increasing the speed of your run.
In a modern CPU, cache is arranged as a hierarchy. Closest to the CPU is L1 (Level 1), which is fast and doesn’t hold much. If the data isn’t in L1, L1 looks to see if it’s in L2. If it’s not there L2 looks to see if it’s in L3. If it’s not there, it looks in the next level again for however many levels of cache your CPU has. Eventually if it can’t be found in any level, it is obtained from RAM.
| Level | Capacity | Lookup Time (nanoseconds) |
|---|---|---|
| L1 | 2-8 KB | ~1 ns |
| L2 | 256-512 KB | ~3 ns |
| L3 | 1024-8192 KB | ~12 ns |
| RAM | 8-32 GB | ~100 ns |
Capacities and speeds are examples only. Actual number vary.


Heat the olive oil in a non-stick frying pan then add the sliced onion and cook on a medium heat until completely softened, so around 15 mins, adding a little splash of water if they start to stick at all. Crush in the garlic and cook for a 2-3 mins further, then add the butter. Once the butter is foaming a little, add the mushrooms and cook for around 5 mins until completely softened. Season everything well, then tip onto a plate. Tip the flour into a bowl with a big pinch of salt and pepper, then toss the steak in the seasoned flour. Add the steak pieces to the pan, splashing in a little oil if the pan looks particularly dry, and fry for 3-4 mins, until well coloured. Tip the onions and mushrooms back into the pan. Whisk the crème fraîche, mustard and beef stock together, then pour into the pan. Cook over a medium heat for around 5 mins. Scatter with parsley, then serve with pappardelle or rice.


ORDERLY
- run and supervise processes
orderly [<SUPERVISOR-FLAGS>] [ -- <PROCESS-FLAGS> ]+
orderly Provides ordered starting, supervision and stopping of a collection of processes. orderly starts a list of processes in order, then monitors them with provided health check scripts.
On failure, processes are stopped and restarted in a well specified order. Scripts can also be provided to cleanup after a failed process (unmounting filesystems, deleting files, etc.).
Arrangement of orderly invocations in a tree hierarchy allows the creation of fault tolerant process supervision trees.
The size of the start pool, when this pool less than one and a (re)start is required orderly aborts. Each (re)start decreases the pool size by one. Note that the initial start is counted towards the quota, so the pool size must be at least 1 for a successful startup.
The rate at which restarts are added into the (re)start pool.
An alias for the rate at which restarts are added into the (re)start pool.
An alias for the rate at which restarts are added into the (re)start pool.
If specified, a file to be written containing the current status of orderly. The file will contain either "STARTING", "RUNNING". orderly transitions from starting, to running after all procesess it is controlling have started successfully at least one time. The main use for this file is for creating nested orderly supervision trees that start in order.
An optional hook to run when the first startup completes successfully,
An optional hook to run before each restart that is triggered by a command failure.
An optional hook to run when orderly encounters an unrecoverable error, and must abort operation.
An optional hook to run just before orderly exits after a clean shutdown.
Shorthand for setting all lifecycle hooks to the same script, in this case env variables can disambiguate the action to take.
The number of seconds to wait for a given hook before giving up and triggering a restart. A negative value means no timeout.
The amount of time in seconds to wait between health check loops.
If set, health checks that pass do not cause any logging output.
The name of the service, passed to all callbacks under the env variable as 'ORDERLY_SERVICE_NAME'.
The command invoked by orderly to launch a supervised process. If this program exits, it will trigger a restart.
An optional command invoked concurrently with the service, it should exit with a 0 exit code when this process is ready and the next process can be started.
An optional command invoked periodically as a health check. If this commands times out or returns an unsuccessful exit code, a restart will be triggered. This check is in addition to ensuring the run process has not exited.
An optional command to shutdown the supervised process. If not specified, orderly will send SIGTERM to terminate the supervised process.
The shutdown command may be run if a command start times out, a sibling process dies and the server needs to restart, or orderly is shutting down.
An optional command to cleanup any resources the running process may have left. If it exits with an unsuccessful exit code, a restart will be triggered. Process cleaning should be idempotent, and always happens in reverse order to process startup.
Shorthand for setting all commands to the same script, in this case env variables can disambiguate the action to take.
The number of seconds to wait for a given command before giving up. A negative value means no timeout.
The amount of time to wait after a shutdown command before terminating the child with a SIGKILL if it does not exit on it's own.
The following env variables are passed to any specified process scripts.
The name of the process being managed.
One of START_COMPLETE, RESTART, FAILURE, RUN, WAIT_STARTED, CHECK, SHUTDOWN, CLEANUP depending on which action orderly is requesting.
The pid of the orderly process.
The pid of the supervised process, if it is running.
orderly shuts all processes down with the provided or default shutdown commands in reverse order.
orderly exits with a zero exit code only if shutdown after a SIGINT or SIGTERM occured with no errors.

sleep 1
kill -SIGINT "$pid"
wait

there are areas to test low level to high level characters, iddilicus's level up room modified, pretty much everything you can get in game and some custom noodling stuff, an alignment changer and an xp dropping pixie.
It's a nice quiet litle mod to build your character up a level at a time, gives ya time to think and time to redo stuff in the nwn setting.

Transport the quintessential flavours of the Mediterranean into your kitchen with our delicious recipe for paella.
Heat the oil in a 36cm/14in paella pan or a very large frying pan set over a medium heat. Season the chicken thighs with salt and freshly ground black pepper and fry for five minutes, turning regularly until lightly coloured. Add the chorizo and cook for a further minute.
Add the garlic and cook for a further couple of minutes, then push everything to one side. Add the tomatoes and fry for a few minutes, then mix everything together and sprinkle in the paprika and lemon zest. Pour in all but a large ladleful of the chicken stock and return to the boil. Add the bay leaves, thyme and green beans and season with a little salt.
When the chicken stock has returned to the boil, turn down to a simmer and sprinkle in the rice, trying to get it into as even a layer as possible. Pour in the saffron and stir – this is the only time you should stir your paella once the rice has been added! Bring to the boil again, then simmer for 5 minutes.
Turn the heat down and leave the rice to simmer slowly – this should take between 12–15 minutes. If it is getting dry, taste – if still a little too firm (crunchy), add a little more stock. When you are satisfied the rice is al dente, arrange the mussels and prawns over the paella. Cover with a damp teacloth or a lid if you have one and wait for the mussels to steam open and the prawns to turn pink. Serve with lemon wedges.


This site is made as a submission for the final project at the minor Programming at the University of Amsterdam. For the final project we had to choose a case and creates visualisations using javascript and d3. The case chosen for this project is the issue of immigrants in the Netherlands with a specific interest in immigrants and people from immigrants background in relation to criminality.


HTML and CSS are both used to create web pages, in a similar way that we would create a poster.
HTML is like the blank paper with a pencil draft on it, it would be like a basic outline of all the elements you wanted to put on the page.
CSS is like the paint and ink you use to create the background colours, the pictures and fonts styles and sizes. Its what makes the page pretty.
When you drive to work in the morning, there is a particular set of things you do, and responses from the car, that get you to your destination.
A similar process is flow control and looping when executing code.
Turning the key and putting the car into gear is like giving an input to the engine to execute a pre-determined set of steps - If the key turns, flick a switch to the starter motor and start the engine.
As with code, inputs can be variable - you can put the car into reverse, or first, or let it idle while you turn the heater. The inputs that are chosen tell the electronics in the car to execute certain steps - IF the user puts the car to reverse, move the car, ELSE idle the car. This would be an If/Else statement if our cars understood code.
The Dom sounds like he would be a cool, fashionable gay friend who always refered to himself in the 3rd person and smelt good - but alas, its an interface that shows the HTML on a page as a tree of objects.
DOM stands for Document Object Model and helps developers to work more communatively (im not sure if thats actually a word) by being able to see and manipulate the code for all web pages. The changes arent permanent, unless you have higher access or spooky powers.
An Array is a list of 'things', usually strings. As you can imagine, it has a length - for example, a list of 3 things. You can access data from it by calling the list and asking for an item in a certain position, such as the second item.
I like to think of an object like everyday objects - such as a basketball, which has properties like its colour, and the property has a value, in this case orange. To call data from objects, we access the property, like colour, which returns the value. In the case of the basketball, the value returned would be orange.
Functions are basically a set of instructions written in code. The computer executes these when the function is called. A function that is the property of an object is called a Method. They are useful as you dont have to repeat instructions in your code. The analogy on Watch and Code was that its like a recipe for a sandwich that you can sub in different fillings for.

When Tanasha Donna hit the studios with her baby
Dar es Salaam. Diamond Platnumz’s Kenyan girlfriend, Tanasha Donna the radio presenter is not taking things easy at all, already she is back in studio making music less than two months after she gave birth.
Tanasha posted a picture of her and her son Naseeb Junior in the studio with the caption, “My happiness in one pic.”
It was not clear whether the studio is in Dar es Salaam of her home city Nairobi.
The new mother added that they will be celebrating their son’s 40 on 26 November, a tradition Diamond has upheld with two of his other children, Lattifah and Nillan.
Before their son was born, Tanasha had declined to share his name for fear that evil people will harm him.
Speaking during one of her Instagram live videos, Tanasha, who was responding to a fan’s question explained that she and Diamond agreed to keep their baby’s name private until he was born.

''I am afraid that bad and evil people will harm him, we have already discussed the name but we cannot share it at the moment,'' she said.
Apart from withholding her sons name, Tanasha was very protective of her child even before he was born, hiding him from the public for as long as she could.

Press release
Ofqual is today (30 June) announcing the publication of revised GCSE maths sample assessment materials by AQA, OCR, Pearson and WJEC Eduqas.
Today’s announcements reflect actions agreed with Ofqual following the conclusion of a recent research programme.
Ofqual has conducted qualitative and quantitative research on the revised materials to confirm that there is greater consistency of difficulty between the boards’ papers and that each board’s specification effectively differentiates across the full ability range of GCSE maths students.
Commenting on the announcement, Glenys Stacey, Chief Regulator, said:
The new sample papers are now judged to be very similar, in terms of expected difficulty, and also likely to differentiate across the full range of students. They meet our requirements.
We appreciate that teachers will want to choose a specification that best suits their students and the way that they teach, with the assurance that, whichever board they choose, standards will be comparable when students sit their exams in 2017 and beyond. We are already looking ahead to 2017, and new checks and balances we will put in place beforehand to make sure that the real exams are set at a comparable level of difficulty.
Full details of today’s announcement can be found in our post research review and regulatory summary .
Ofqual is also today publishing the analysis and decisions of its recent consultation along with revised conditions and guidance .
Today’s announcement reflects the actions taken by the exam boards since Ofqual produced the findings of its initial research in May. Ofqual concluded that OCR, Pearson and WJEC Eduqas needed to refine their higher and foundation tier papers to sufficiently differentiate across student abilities, and AQA needed to lift, to some extent, the expected difficulty of their foundation tier papers.

I used to be interested in mobile game development, and when it comes to small indie groups releasing monetized games, it is vital to protect cheating in order to keep up revenue. Frequently targeted values are gold, EXP, coins, etc. These values are critical so they must be protected in memory and on disk. I did some research in the past on how to deal with this problem, and here are my findings.
The two common ways of hacking games is save-game editing and memory editing.
If the game saves are not encrypted, it is easy to access them and edit them inside a HEX editor to search for and change key values. It is easy to inspect the changes from one save to another if the data layout is consistent.
Once modified, the save can be downloaded on the internet as there is no check that the save belongs to a specific device.
Solutions:
Instead of modifying the save game, it is possible to scan the memory as the values are modified by the game. Once the memory locations of key values are identified, they can be patched in memory without the game noticing and they will then be saved as regular values for future sessions.
Solutions:
Of course, these solutions are mainly for games that don't require a connection to a server to play. When there is a server in the equation, these key values can be stored and modified on the server so cheating is almost impossible. But for smaller groups of developers that can't handle the bandwidth, these solutions are a relatively easy way of protecting your game.

Part of wireframing your site is making a UI/UX flowchart to organize the way the different sections of your web site connect. These might be different html documents linked together to create a site, or a single html document with multiple distinct sections.
Pagination
Pagination is a design technique where you attempt to fit everything onto the screen at once, as if reading a printed page. Pagination requires the use of responsive design to accommodate displays with different dimensions and resolutions.
In order to appropriately size paginated sections, we need to be able to reliably measure the viewport width and height. vw and vh are css measurement types used to position and size elements based on the complete viewport dimensions.
100vw = 100% viewport width
100vh = 100% viewport height
vw/vh is different from using the % measurement because they are always based on the viewport dimensions, regardless of how nested the html element is that you are applying it to.
Paginated Linking
Linking to different sections within the page is just as easy as linking to other pages. This gives the user the option to scroll through all the content or use a navigation menu to select a specific section to view.


Online course 6: LAN scalability, adding pollers
Hi,
This is our 6th online course. After the 5th from Seb that was about creating checks, you got numerous ideas about what to check and make your IT even stronger. But more checks means more load, and maybe one poller is not enough now :)
We will look in this course about one #shinken core feature that will help you there: adding pollers is just tooooo easy :)
Let's start with two standard 2.0 installation in two linux box. We will disable all the daemons on the second box but not the poller.
You will be able to follow this tutorial on video soon.
Our setup with 2 linux boxes
We will have 2 linux and we want the second to be just a poller available for the first box shinken. The box courses-a will be our primary one, and courses-b the extended poller one. We just installed shinken in the 2 boxes. Both got a valid dns entry :
root@courses-a$ cat /etc/hosts
[...]
<IP_ADDRESS> courses-a
<IP_ADDRESS> courses-b
root@courses-b$ cat /etc/hosts
[...]
<IP_ADDRESS> courses-a
<IP_ADDRESS> courses-b
We want to have something like this :
Preparing the first box (master)
Let's first focus on the courses-a
box. This will be quite quick. The poller we want to enable on the courses-b
box will have to connect to the scheduler
on the courses-a
to get its job. It will have the scheduler
address and port from a configuration send by the arbiter
.
But the default address of the scheduler-master
is with the good port (7768), but with the localhost
address. This won't be a problem for the arbiter to reach it, but if the poller on the courses-b
try, it won't have a change to reach the courses-a scheduler
:p
So all we need to do is to setup the LAN address on the scheduler
definition object:
root@courses-a$ vi /etc/shinken/schedulers/scheduler-master.cfg
define scheduler {
scheduler_name scheduler-master ; Just the name
address courses-a ; IP or DNS address of the daemon
port 7768 ; TCP port of the daemon
spare 0 ; 1 = is a spare, 0 = is not a spare
weight 1 ; Some schedulers can manage more hosts than others
timeout 3 ; Ping timeout
data_timeout 120 ; Data send timeout
max_check_attempts 3 ; If ping fails N or more, then the node is dead
check_interval 60 ; Ping node every N seconds
modules
realm All
skip_initial_broks 0
use_ssl 0
}
Now the second box :)
All we need now it to look at the courses-b
box, and let's disable LOT of daemons ^^
You must set daemon_enabled=0
to the following files:
root@courses-b$ grep daemon_enabled /etc/shinken/daemons/*ini
/etc/shinken/daemons/brokerd.ini:daemon_enabled=0
/etc/shinken/daemons/pollerd.ini:daemon_enabled=1
/etc/shinken/daemons/reactionnerd.ini:daemon_enabled=0
/etc/shinken/daemons/receiverd.ini:daemon_enabled=0
/etc/shinken/daemons/schedulerd.ini:daemon_enabled=0
And also on the arbiter that is installed by default on the courses-b
:
root@courses-b$ grep daemon_enabled /etc/shinken/shinken.cfg
daemon_enabled=0
Now you can restart your shinken daemons on the courses-b
and look if only the poller is really started:
root@courses-b$ /etc/init.d/shinken -d restart
root@courses-b$ /etc/init.d/shinken status
Checking status of scheduler
scheduler NOT RUNNING
failed!
Checking status of poller
poller RUNNING (pid 25504)
. ok
Checking status of reactionner
reactionner NOT RUNNING
failed!
Checking status of broker
broker NOT RUNNING
failed!
Checking status of receiver
receiver NOT RUNNING
failed!
Checking status of arbiter
arbiter NOT
failed!
We temporary put the poller in debug mode so we will have all it's logs available to see the good connexions and internal data.
So now that our courses-b
poller is ok and no other daemons will annoy it, we can declare it to the arbiter side on the courses-a
server:
root@courses-a$ cp /etc/shinken/pollers/poller-master.cfg /etc/shinken/pollers/poller-courses-b.cfg
root@courses-a$ vi /etc/shinken/pollers/poller-courses-b.cfg
define poller {
poller_name poller-courses-b
address courses-b
port 7771
spare 0
manage_sub_realms 0 ; Does it take jobs from schedulers of sub-Realms?
min_workers 0 ; Starts with N processes (0 = 1 per CPU)
max_workers 0 ; No more than N processes (0 = 1 per CPU)
processes_by_worker 256 ; Each worker manages N checks
polling_interval 1 ; Get jobs from schedulers each N minutes
timeout 3 ; Ping timeout
data_timeout 120 ; Data send timeout
max_check_attempts 3 ; If ping fails N or more, then the node is dead
check_interval 60 ; Ping node every N seconds
modules
use_ssl 0
realm All
}
So the only modification you need are the poller_name
and address
parameters. You can keep the others by default.
Restart and look at your success :)
Then restart the arbiter shinken
on the ourses-a
server:
root@courses-a$ /etc/init.d/shinken-arbiter restart
The arbiter-master
will load the new poller and will give it some new job, like taking checks from the courses-a's scheduler
:)
If we look at the courses-b
logs, we can see the connexion:
root@courses-b$ grep 'scheduler-master' /var/log/shinken/pollerd.log
[1410170010] INFO: [Shinken] [poller-courses-b] Init connection with scheduler-master at http://courses-b:7768/ (3s,120s)
[1410170010] WARNING: [Shinken] [poller-courses-b] Scheduler scheduler-master is not initialized or has network problem: Connexion error to http://courses-a:7768/ : couldn't connect to host
[1410170012] INFO: [Shinken] [poller-courses-b] Connection OK with scheduler scheduler-master
[1410170012] INFO: [Shinken] [poller-courses-b] Init connection with scheduler-master at http://courses-a:7768/ (3s,120s)
[1410170012] INFO: [Shinken] [poller-courses-b] Connection OK with scheduler scheduler-master
Don't worry about the WARNING here. It's just the poller is too fast for the scheduler to be fully running with a configuration. If you got some few seconds after a Connection OK
it means you are ok :)
So now you can look at this poller and look if it really get new checks from the scheduler:
root@courses-b$ tail -f /var/log/shinken/pollerd.log
...
[1410170033] DEBUG: [Shinken] [0][scheduler-master][fork] Stats: Workers:1 (Queued:1 TotalReturnWait:1)
...
Here the poller ask the scheduler and get one check and one other result to return to this scheduler. You will have one line by worker and by scheduler. So this poller is working great :)
Did we forgot something?
But we forgot some things: pollers are launching check plugins, located in the /var/lib/shinken/libexec/
directory or in the /usr/lib/nagios/plugins/
directory for standard nagios plugins ones. And here you poller got none of them :)
So for each pollers you need to add the same plugins, so for example here you can just :
root@courses-b$ apt-get install nagios-plugins
for the nagios plugins, and:
root@courses-a$ scp -rp /var/lib/shinken/libexec/* root@courses-b:/var/lib/shinken/libexec/
And you will have all you need on the courses-b
poller.
The next course
The next course will be an extension of this one. Here all checks are distributed in all our pollers, in a round robin way. But maybe we want to dedicate one box for a specific checks or hosts? We will see this in the next course, about the poller tags, and one classic usage for this: pollers in DMZ :)

HexEdit Pro allows you to edit files of more than 4 Gbytes if you have an NTFS filesystem (under NT/2000/XP). For files this large the scrollbar resolution makes the vertical scrollbar virtually useless for moving to a particular address. For huge files the method for selecting a large block of bytes as explained in How Do I Make a Large Selection? becomes too cumbersome if not impossible. In this case you need to use the following method. Note that the instructions below assume the default keyboard setup.
Double-click on the first byte of the selection to set the mark (see the Set Mark Command). Then use the hex or decimal address tool to jump to the end of the desired selection. For example, press Alt-J type ABCD and press Enter to jump to address ABCD (hex). Then use the Extend To Mark Command (menu item: Edit/Mark/Extend to mark) to select all the bytes from the mark to the cursor.
You may then perform operations on the selection such as writing it to a file. Of course, such operations may be slow to complete if you have a very large selection.

In July 2014 I represented my university at an international event at the University of New South Wales, Sydney, Australia.
The summer school was about “Smart Cities” and 5 different strands relating to smart cities were considered including connectivity, resilience, inclusiveness, healthiness and beauty.
I was involved in a team project which proposed a solution relating to the importance of and efficient use of public space in future cities as population densities rise.
More coming soon.

Former first lady Mrs Aguiyi-Ironsi full of life on her 90th birthday (video)
Every second, human beings grow despite not being aware of the changes their body is going through until they look back and remember their youthfulness.
Many times some individuals are not lucky enough to live till old age even if they did all the right things, such as staying away from harmful substances and leading a healthy life.
On the other hand, some people are fortunate to live a long and meaningful life despite experiencing traumatic things in the past. That seems to be the case of Nigeria’s former first lady, Victoria Aguiyi-Ironsi.
In a video that was shared on social media via Twitter by one Olaudah Equiano, Victoria was seen looking very healthy and agile as she danced to celebrate the occasion of her 90th birthday.
In the short clip, Victoria, who despite supporting herself with a walking stick seemed very happy as she danced to a Tekno song. The 90-year-old woman who wore green native attire paired with coral beads seemed very happy to be alive.

NINE MONTHS A film review by Melissa Martin Copyright 1995 Melissa Martin
I will truly expect every professional critic to absolutely hate this movie.  The film is awful on that level.
But if the public loves the film as much as I did, it'll be a hit.
This is a great comedy, more in the tradition of DUMB & DUMBER than something oh, say, cleverer, like CLUELESS.  The script is unquestionably cheesy and cheap, but it's hilarious ... which is all that really counts.
Hugh Grant, who I thought was horrible in FOUR WEDDINGS AND A FUNERAL (actually, a friend and I didn't even finish the film, we thought it was pretty awful) and I never liked previously anyway, turns on the English boy charm like a firehose. I walked into the theatre with a slight loathing for him, and by the middle of the movie I wanted to have his child. :-) He is absolutely hilarious and has an obvious knack for corny comedy. He even managed to switch gears and carry something more emotional ... during the middle of the film, at one of the fleeting moments of seriousness, I almost cried (seriously) because of the look in his eyes.
Julianne Moore is a goddess given actress form. With her strangely stunning, delicate average-girl appearance and high-quality acting, we get a character to put our heart into, unlike the childish Samuel (Grant). She carries her performance through well and is a pleasure just to look at.
Unfortunately, Moore and Grant do *not* make a cute couple. There are no sparks nor chemistry between the two characters, which is unfortunate considering the appeal of the two.
I never liked Tom Arnold either, and so was surprised that I didn't sit back and wish he was not in the entire movie. In fact, he was rather enjoyable.
Joan Cusack is lovely as Arnold's also-pregnant wife (which was a sad plot attempt, a little too much like a coincidence).
Robin Williams, as is natural for the man, is side-splitting funny and a darned fun ride. It is unfortunate that he got so little time : I would have preferred him to take the place of both Cusack's and Arnold's characters.
The most unfortunate thing about this film is somewhat in the vein of ACE VENTURA : PET DETECTIVE, it has been billed as a kind of semi-family movie. I saw a huge number of obviously under-13 kids (I'm thirteen, I should know) get tickets and go in, when it was very clearly stated 'PG-13.' What particularly saddened me was that one sweet ol' grandma had taken two children, about seven and ten, to the film. There is a *lot* of sexually explicit and lewd writing here. It is very funny at times, but completely inappropriate for anyone under my age (especially with parents, which is what we tend to call "unbelievably embarrassing"). There is also one prelude-to-a-sex-scene, where Julianne Moore gets to participate in a rather demeaning strip-tease.
I can't really write much about this film, because there isn't much to write about.  Not exactly the kind of "don't-miss-comedy-of-the-year," but easily merits a few good laughs if you have nothing else better to see.
Of course, the best films of the year remain POCAHONTAS and APOLLO 13.
WATERWORLD comes out this week. Can't wait to review it for the reading public. :-)
