T++
T++ is a high-level programming language designed for the R3X system.
Let's begin with a "Hello, World!"
First compile the compiler using the GNU Compiler Toolchain (YOU WILL NEED IT WHILE RUNNING TOO!). If your system has the required tools, then it's simply a
export PREFIX="<path where you want the executable to be stored>"
./buildutils.sh
Next get a copy of the "Flat Assembler", for your system from flatassembler.net, and
place it in your PREFIX directory
Then you can export it in your PATH like this:
export PATH=$PATH:$PREFIX
export STDLIB_R3X="$PREIFX/include" # for standard library
NOTE: the T++ compiler for R3X uses GCC as it's preprocessor, you will need the gcc toolchain in order to compile R3X programs!
Let's begin with some code? Shall we? :)
function main(0)
/* This is a comment */
/* Print Hello, world to screen */
print "Hello, World!"
/* Exit */
end
endf
Using a text editor, save this file as "hello.bas", and run t++, with the following:
t++ -s hello.bas -o hello.asm
Now it should generate an assembler file, however if you use FASM to compi
rxvm -exe ./hello.exe
You should see the words "Hello, World!" on the output screen. If you press a key, then the program will exit.
Variable Assigment
T++ is a typeless language, meaning one variable is not limited to one type.
All variables are assigned with the "let" keyword. The first "let" keyword is supposed to initialize the variable.
let int = 27+3
let str = "Hello, World!"
...
Global variables can defined like this:
global myvar
..
NOTE: global variables can't be assigned to while declaration, you can assign them inside a function like this:
..
let <global>myvar = 0
You can also use them in expressions like this
..
/** without the <global> prefix, all variables are assumed to be local...
let x = 1+a*<global>globalvar
...
Memory Allocation
Memory allocation is supported through the "alloc" variable, use it like this:
let buffer = alloc(size)
"buffer" could be anything you wish, now buffer = pointer to a region of memory mapped as data.
Memory Access Operators
There are "memory access" operators which can help you access certain region in memory, these are:
int32_ptr(addr) - 32-bit memory access
int16_ptr(addr) - 16-bit memory access
int8_ptr(addr) - 8-bit memory access
To set a location in memory, you can make use of the "let" keyword:
// Set a 32-bit value at memory location 0x1000
let int32_ptr(0x1000) = 0xFFFFFFFF
// Set a 16-bit value at memory location pointed by "buffer+5"
let x = 65535
let int16_ptr(buffer+5) = x
...
Program/Control Flow and looping
goto
The "goto" keyword monitors function-specific program flow through a system of labels.
A label can be declared with a semicolon in front of it:
...
:label
...
You can then jump to this label using "goto":
...
goto label
...
You can also "gosub", if you want recursion, note that you would need to return as well. [You may rather use functions for this!]
:label
...
do stuff
...
// This will be explained in detail under "functions"
return 0
...
gosub label
...
code after this will run as expected
NOTE: Labels cannot be used in expressions!
Control flow in T++ is achieved through 2 keywords: "IF" and "WHILE"
The "if" keyword compares two expressions and then performs a statment, (usually a goto to a label)
...
if (a := 5) goto yes
if (a != 5) goto yes
if (a < 5) goto yes
if (a > 5) goto yes
if (a <= 5) goto yes
if (a >= 5) goto yes
// Labels are scope-specific
:yes
...
The "while" keyword loops through the code between it and another keyword "endw" provided the condition is true [like if] (end while).
...
while (a < 5)
...
let a = a + 1
...
endw
Functions
Functions are certain pieces of code which are organized together, and expect input and give output. In the "Hello, World" example we saw,
a "function main, 0" -- This is the "main" function and is called by libR3X after it's initialization.
Here's a simple example on how to use functions:
function addtwonumbers(2)
let a = $1
let b = $2
return a + b
endf
The above code declares a function with 2 arguments as "add2numbers". It then uses a local variable called a and b to add it's first and second argument (referenced
by $1, and $2 respectively), to store the result of the addition. It then returns a+b.
NOTE: $1 + 2 is not same as let a = $1 let a = a + 2! "$1 + 2" means load the third argument (anything after a '$' is counted as a single expression!)
It is required to write a function in this format:
function function_name(no. of arguments)
let name_of_first_argument = $1
let name_of_second_argument = $2
...

This must be used like:
...
let name_of_arg = $1
while(name_of_arg <= 15)
...
endw
...
This can now be called like this, from another function:
...
let result = @add2numbers(57, 90)
...
Or you can simply call it like this, and trash the result:
@add2numbers(57, 90)
You can also pass expressions, like this:
@add2numbers(myvar1*20+60, myvar2-15)
You must always return, or not returning from a function causes undefined behaviour, for functions that don't
intend to return anything use:
...
return 0
Structures
Structures are like "patterns" in memory.
In TBC++, structures are declared like this:
struct mystruct([number of members])
int8/int16/int32 membername
...
ends
You can then use the sizeof keyword to get the size of the structure and allocate memory for it.
mystruct01 = alloc(sizeof(mystruct))
Then you can access it using the 'typecast' (<>) operator.
let a = <struct mystruct>mystruct01.[member name]
You can also use the 'let' keyword to assign a value to a member.
let <struct mystruct>mystruct01.[member name] = expression (1+2, a+b, a+3 etc.)
Internal functions
T++ provides 4 internal functions for a program to use.
print
The "print" function outputs a string / integer to stdout. The usage is shown below:
...
// Print a literal string
print "hello"
// Print a string stored in a pointer
print $variable
// Print an integer
print my_int
// Print a string + integer
print "hello: "; my_int1, my_int2+1, my_int3*3 ...
input
The "input" function inputs a string from stdin into a variable. The usage is shown below:
...
let size = 256
let pointer = alloc(size+1) // 1 for 0 terminator
input pointer, size
...
you can use it like:
if(@r_strcmp(pointer, "hello")) {
//...
}
...
alloc
The "alloc" function allocates a region of memory, by size, and then puts the pointer into a variable
#! Allocate 256 bytes and assign pointer to x
x = alloc(256)
end
The "end" function simply quits the program.
Inline assembler
Inline assembly can be achieved through the "asm" keyword, like this:
...
asm "loadrr R1, R5"
asm "pushr R1"
asm "popr R5"
...
Of course, you're !not! supposed to mess up the stack, while doing inline asm, ALWAYS restore it before resuming back to
tbc code.
If you want to refer to a variable's address, you can do:
function myfunc, 0
...
let var = 5
// Address of variable = v[function name].[variable name]
asm "loadr R0, vmyfunc.var"
Labels can be used in a similar way:
function myfunc, 0
...
:label
...
// Address of label = l[function name].[variable name]
asm "loadr R0, lmyfunc.label"
"addresof" and "raw_call"
The "addressof" operator gives an address of a local variable or function in memory.
Usage:
function x(0)
...
endf
...
let a = addressof(@x) // Address of function x
let b = addressof(a) // Address of variable a (locals ONLY!)
The "raw_call" operator will, on the other hand, call an address.
/* raw_call works like this:
@raw_call(function_address, number_of_arguments, argument1, argument2, ..., ...)
*/
// call address 0x14000
@raw_call(0x14000, 0) /* 0 args */
// call value of a with 3 args
@raw_call(a, 3, 1, 2, 3)
Floating Point Numbers
Floating Point Numbers are represented like: 30.3256 (note the dot).
If you want an absolute number, you must do something like: 30.0
You are allowed to use floating point numbers, however you must use certain operators to do operations on floats.
add_f(expression, expression) : add two floating point numbers, given out by expression
mul_f(expression, expression) : multiply two floating point numbers, given out by expression
div_f(expression, expression) : divide two floating point numbers, given out by expression
mod_f(expression, expression) : do a modulo operation on two floating point numbers, given out by expression
Adding floating point integers and conventional
Adding floats and integers together requires another operator: conv_i/conv_f
Basically, conv_i rounds off a float to it's nearest integers and then converts it to a normal integer.
conv_f on the other hand converts an integer to floating point representation.
See float.bas for example usage.
Operators
These are the following operators present in the language:
Highest precedence:
right_shift(number, bits) - Right shift
left_shitf(number, bits) - Left shift
& - Bitwise AND
| - Bitwise OR
^ - Bitwise XOR
neg(expr) - Bitwise NOT (~)
not(expr) - Logical NOT (!)
Higher precedence:
* - Multiply
/ - Divide
% - Modulo
Low precedence:
+ - Plus
- - minus
!= - Not equal to
&& - logical and
|| - logical or
!= - Not equal to?
:= - Equal to?
>= - Greater than or equal
<= - Lesser than or equal
External functions (Dynamic Library and native) and DL creation
Creating a dynamic library in T++ is very simple, just pass the "-d" parameter after specifying file input and output
options.
You can now use functions from your dynamic library into your application like this:
extern (test_func, "lib.ro", 0) /* extern (function_name, "library_name.ro", no_of_arguments) */
function main(0)
...
@test_func()
...
endf
Native functions can also be used, in order to use them, just do this:
native (test_func, "lib.so", 0)
And call them, just like you would call a normal function.
Preprocessor
t++ calls GCC first to do the preprocessing (using options -E and -P), which means you can use all C preprocessor features!
Including another file is done like:
#include "somefile.h"
Definitions can be done like:
#define MYVAR 1
...
/** And then can be used like **/
let x = MYVAR
You can also define expressions:
#define ADD_1(x) (x+1)
...
let q = ADD_1(q)
Using the R3X standard library
The R3X standard library for T++ is now available. The features include:
1. String Handling
2. Memory Access Routines
3. String Routines
4. Sockets
5. File I/O
6. Math operations
The standard library is provided by the virtual machine. The handle used to refer to the standard library
is "rstdlib".
A header file is given in src/lib/rstdlib/include/rstdlib.h to be used by programs.
Please see src/lib/rstdlib/readme.txt for more details on library's functions.

The XLib surface is used to render cairo graphics to X Window System windows and pixmaps using the XLib library.
Note that the XLib surface automatically takes advantage of X render extension if it is available.
cairo_surface_t * cairo_xlib_surface_create (Display *dpy
,Drawable drawable
,Visual *visual
,int width
,int height
);
Creates an Xlib surface that draws to the given drawable. The way that colors are represented in the drawable is specified by the provided visual.
Note: If drawable
is a Window, then the function
cairo_xlib_surface_set_size()
must be called whenever the size of the
window changes.
When drawable
is a Window containing child windows then drawing to
the created surface will be clipped by those child windows. When
the created surface is used as a source, the contents of the
children will be included.

void cairo_xlib_surface_set_size (cairo_surface_t *surface
,int width
,int height
);
Informs cairo of the new size of the X Drawable underlying the surface. For a surface created for a Window (rather than a Pixmap), this function must be called each time the size of the window changes. (For a subwindow, you are normally resizing the window yourself, but for a toplevel window, it is necessary to listen for ConfigureNotify events.)
A Pixmap can never change size, so it is never necessary to call this function on a surface created for a Pixmap.

pod 'SwiftYNAB', :git => 'https://github.com/andrebocchini/swiftynab.git'
end
- Run
pod install
Swift Package Manager
You can also use the Swift Package Manager.
Instructions on how to add a Swift Package dependency to your project can be found here.
Trying it out
Personal API access token
The project comes with a small iOS demo that shows you how to use the framework. If you want to try that out, or if you want to write your own code, you will need a personal API access token.
Make sure you go here and get one:
https://api.youneedabudget.com/#personal-access-tokens
Sample code
Once you have your personal access token, you can use it to try out the framework in your app. Start by creating a new project and at the top of the file where you plan to use SwiftYNAB, add:
import SwiftYNAB
Then, you can try it out by writing something like:
let ynab = YNAB(accessToken: "TOKEN_GOES_HERE")
Task {
do {
let budgets = try await ynab.budgets.getBudgets()
for budget in budgets {
print(budget.name)
}
} catch {
print("Uh oh, something went wrong")
}
}

The Java Platform, Standared Edition 1.4 (Java SE 1.4) included the Crimson reference implementation for JAXP 1.1. The Java platform, Standard Edition 6 (Java SE 6) includes a reference implementation for JAXP 1.4 based on the Apache Xerces library.
Because these implementations come from entirely different codebases, and because the JAXP standard has evolved from 1.1 to 1.4, there are some subtle differences between the implementations, even they both conform to the JAXP standard. These two factors combine to create the compatibility issues described in this guide.
See Release Notes.
While the reference implementation in Java SE 1.4 supported the DOM Level 2 API, the implementation in Java SE 6 supports the DOM Level 3 family of APIs. This section covers the impact of those changes on programs that used the JAXP 1.1 reference implementation:
For more information, see the complete list of changes in the DOM Level 3 Changes appendix.
In DOM level 3, additional methods were defined in the following interfaces:
Attr
Document
DOMImplementation
Element
Entity
Node
Text
The added methods only affect applications that implement the interfaces directly, and only when the application is recompiled. Applications that use the factory methods to obtain implementation classes for these interfaces will have no problems.
These changes affect an application that reads in XML data into a DOM, makes modifications, and then writes it out in a way that preserves the original formatting.
In JAXP 1.1, extraneous whitespace was automatically removed on
input, and a single property (ignoringLexicalInfo
) was
set to false
to preserve entity nodes and CDATA nodes,
for example. Including the additional nodes made the DOM somewhat
more complex to process, but because they were there, adding
whitespace output (indentation and newlines) produced highly
readable, formatted version of the XML data which closely
approximated the input.
In JAXP 1.4, there are four APIs that the application uses to
determine how much lexical (formatting) information is available to
process, using the following DocumentBuilderFactory
methods:
setCoalescing()
To convert CDATA nodes to Text node and append
to an adjacent Text node (if any).
setExpandEntityReferences()
To expand entity reference nodes.
setIgnoringComments()
To ignore comments.
setIgnoringElementContentWhitespace()
To ignore whitespace that is not a significant part
of element content.
The default values for all of these properties is
false
, which preserves all the lexical information
necessary to reconstruct the incoming document in its original
form. Setting them all to true
lets you construct the
simplest possible DOM, so the application can focus on the data's
semantic content, without having to worry about lexical syntax
details.
Note:
When adding new nodes, the application must add any indentation and
newline formatting that is needed for readability, since it is not
provided automatically.
Following are the changes made between SAX 2.0.0 and SAX 2.0.2 that might affect compatibility.
DeclHandler.externalEntityDecl
now requires the parser
to return the absolute system identifier for consistency with
DTDHandler.unparsedEntityDecl
. This may cause
some incompatibilities.
In SAX 2.0.1, an application can set ErrorHandler
,
EntityResolver
, ContentHandler
, or
DTDHandler
to null
. This is a relaxation
of the previous restriction in SAX 2.0, which generated a
NullPointerException
(NPE) in such circumstances.
So the following code is legal in JAXP 1.3:
SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader reader = sp.getXMLReader(); reader.setErrorHandler(null); reader.setContentHandler(null); reader.setEntityResolver(null); reader.setDTDHandler(null);
The
resolveEntity()
method in the
EntityResolver
API now throws
IOException
, as well as SAXException
.
(Before, it only threw SAXException
.)
The vast majority of applications are unaffected by this change,
because the DefaultHandler
implementation class has
been modified to declare the additional exception, and very few
applications use the DefaultHandler
in such a way that
they will run into a problem.
The only way an application can be affected is if it overrides
the resolveEntity()
method and also invokes
super.resolveEntity()
. In that case, the application
won't compile in Java SE 5 until the method is modified to handle the
IOExceptions that super.resolveEntity()
could
throw.
The following new features are recognized :
http://xml.org/sax/features/external-general-entities
To include external general entities.
http://xml.org/sax/features/external-parameter-entities
To
include external parameter entities and the external DTD
subset.
and the following new property:
http://xml.org/sax/properties/xml-string
To
get the string of characters associated with the current event.
For a complete list of Xerces features and properties, see http://xerces.apache.org/xerces2-j/features.html and http://xerces.apache.org/xerces2-j/properties.html.
Note:
One point of compatibility is also worth mentioning. Namespace
recognition was turned off by default in Java SE 1.4 (JAXP 1.1). For
backward compatibility, that policy is continued in Java SE 6 (JAXP
1.4). However, namespace recognition is turned on by
default in the official SAX implementation at www.saxproject.org. While not
strictly a compatibility issue from the standpoint of JAXP, it is
an issue that sometimes comes as a surprise.
Code that uses the standard JAXP APIs to create and access an XSL transformer does not need to be changed. The output will be the same, but will in general be produced much faster, since the XSLTC compiling transformer will be used by default, instead of the interpreting Xalan transformer.
Note:
There may be no significant difference between Xalan and XSLTC
performance for a single run on a small data set, as when you are
developing and testing an XSL stylesheet. But there is a major
performance benefit when using XSLTC on anything larger.
JAXP 1.4 provides the standard XPath API for evaluating XPath expressions. We encourage users to use this API. Xalan-interpretive is not included in the reference implementation. If an application explicitly uses the Xalan XPath API to evaluate a standalone XPath expression (one that is not part of an XSLT stylesheet), you'll need to download and install the Apache libraries for Xalan.
This change does not affect applications that confine themselves to using the standard JAXP APIs. But applications that access implementation-specific features of the XML processors defined in JAXP versions prior to 1.3 will have to be modified.
The change has several effects on previous applications:
The property-values that were used to access the internal implementations must be changed.
Applications that used internal APIs that from the Xalan implementation classes must change the import statements that gave them access to those APIs.
Applications that used internal APIs from the Crimson implementation must be re-coded -- ideally, by using newer JAXP APIs or, if necessary, by using Xerces APIs.
In Java SE 1.4, the fact that JAXP was built into the Java platform was a mixed blessing. On the one hand, an application could rely on that fact that it was there. On the other, most applications needed features and bug fixes that were available in later versions.
But adding new libraries had no effect, because internal classes always take precedence over the classpath. The solution for that problem in 1.4 was to use the endorsed standards mechanism. However, that was a new mechanism, and one which frequently placed an additional burden on the end user, as well as the application developer.
The solution since JAXP 1.3 is to change the package names of the Apache libraries used in the implementation. That change lets a user reference newer Apache libraries in the classpath, so application developers can use them in the same way that would use any other additions to the Java platform.
The new names given to the Apache packages in the JAXP 1.3 reference implementation are shown below:

While XML does not allow recursive entity definitions, it does permit nested entity definitions, which produces the potential for Denial of Service attacks on a server which accepts XML data from external sources. For example, a SOAP document like the following that has very deeply nested entity definitions can consume 100% of CPU time and large amounts of memory in entity expansions:
<?xml version="1.0" encoding ="UTF-8"?> <!DOCTYPE foobar[ <!ENTITY x100 "foobar"> <!ENTITY x99 "&x100;&x100;"> <!ENTITY x98 "&x99;&x99;"> ... <!ENTITY x2 "&x3;&x3;"> <!ENTITY x1 "&x2;&x2;"> ]> <SOAP-ENV:Envelope xmlns:SOAP-ENV=...> <SOAP-ENV:Body> <ns1:aaa xmlns:ns1="urn:aaa" SOAP-ENV:encodingStyle="..."> <foobar xsi:type="xsd:string">&x1;</foobar> </ns1:aaa> </SOAP-ENV:Body> </SOAP-ENV:Envelope>
A system that doesn't take in external XML data need not be concerned with the issue, but one that does can utilize one of the following safeguards to prevent the problem:
entityExpansionLimit
system
property.

IntelliJ, OSX and kdiff3
update: Jetbrains refuses to acknowledge any problem and frankly their support is offensive. At least when its free software you can say you get what you pay for.
 IntelliJ is one of those IDEs. It is the single most frustrating thing I find with that pos (piece of software, of course ;-)). Particularly since it should use the equivalent of the <blink> tag to let you know it happened. Instead it silently puts itself into a state where you can't work for an hour why you try to recover the working state of the configuration files.
This was recently exasperated for me by kdiff3, otherwise a fine merge tool (almost as good as xxdiff), as kdiff3 was apparently saving the merged files with some weird line-endings or encoding. The symptoms were that IntelliJ complained that, 'no content was permitted in the prolog', but it did apparently save NEW content to the configuration file, so it was actually intepreting the file. (!) In the end I took the merged file into another editor and saved the file with Unix line endings and 'UTF8 with no BOM'.
It may actually have been the BOM (Byte-Order-Mark) that killed everything, including compilation on the Linux-hosted build server of Java files, but frankly, I'm now 2 hours behind where I wanted to be so I'll have to leave this for an update.

Convenience & Security Alone Will Not Save the Day
Identity management, which encapsulates the issues of security and privacy, will be one of the most critical factors to ensure that secure m-transactions can successfully scale. Security of an individual’s data will have to become the responsibility of a trusted community, where the risk and rewards of accessing an individual’s data are stacked up for the consumer rather than against. Effectively, the issue of security will dovetail into the larger issue of privacy, and the key will be to find the right balance between disclosure and oversight.
Rediscovering Discover – The Network of Networks
International tourists spent close to $1.4 trillion during their cross-border adventures in 2015. Since international tourism is one of the largest sources of income for a significant number of destinations around the world – in developing countries and developed ones – the banking industry has had to evolve their instruments to ensure that costs associated with international payments are democratized enough, and, at the same time, leverage the opportunity to profitably prime the traveling population to incur significant expenses.
Alipay Storms North America
Brace, PayPal, Google, Apple, Samsung, and anyone railroading customers with proprietary mobile wallets and other payments products. Alipay comes to North America. Slowly, but confidently, Alipay builds its partnerships to storm the market.
FinTech, FIs & Investors Are All Aligned in Addressing Market Needs
It was a busy quarter for deals in FinTech. According to the latest report from FT Partners, banking (including P2P lending), and payments scored the most deals in the period. With innovation in facilitating convenient banking services, comes ever-accelerating fraud risk and a considerate cost at which security breaches come to companies. No wonder forward-thinking teams continue to secure financial support for advanced security solutions, and payments behemoths continue an aggressive push to make payments convenient.

Pseudo-classes are a way to select HTML elements based on their state as opposed to their HTML structure. You can read more about pseudo-classes here. Pseudo-classes must always be applied to an existing selector. Their "flag character" is the colon (":"), as you can see used in the below examples. Here are some of the most popular pseudo-classes.
your name:
These pseudo classes are the ones you are probably most familiar with. Even on this page you've probably noticed that links have different style than paragraph text. The a tag by default sets the text color to blue with an underline, but have you ever seen a purple link? This is the "visited" pseudo-class that applies a different style to links that the user has already clicked. The opposite of visited is "link" which is a link a user has not yet clicked. These two states are mutually exclusive, meaning a link cannot be both at the same time.

The idea behind the Information Flow Analysis plugin is to determine the information content (self information) of raw user input. The intended use of this plugin is during playtesting, to see how complex user interaction is on this abstract level, and how it changes during gameplay or in different parts of the game.
The computation of the information content (not to be mixed up with Entropy) is based on a probabilistic model of the information source. Finding the real probabilistic distribution is usually not possible, thus we have to use/find a model that comes close enough to the real distribution.

SET: I am coming into he last 2 months of my audio engineering course. As a result I am required to shift more stress and anxiety; other than this I am in good running order.
SETTING: Early evening at my flat. Last food approximately 4.5 hours prior (fruit salad). Last drug – cannabis previous evening. Other than this nothing inside of a week.
10mg of 4-AcO-DET freebase was loaded into a glass DMT pipe. Freebase was a dark grey powder.
+:00 I take 5 large lung-fulls of before I am satisfied that no chemical remains. Smoke is actually easy to smoke and not harsh on throat or lungs (I am surprised).
After the 3rd toke the first effects are felt. Very similar to the first .5 seconds of 5-MeO-DMT.
Sweaty hands
Colours are more vibrant.
+:10 – No mental gymnastics at this point but I can see the veins through my hands. Body is feeling fine – no complaints. Lungs feel expanded.
+:15 – No progression of visual or mental effects. Upon standing I have a sense of feeling “taller”.
I do not feel restless.
OEV’s are “expanded”, no morphing or dripping. Colours are vibrant.
CEV’s are no more lucid or intricate than when I am sober.
+:30 – Notice clenched jaw + tightness in stomach.
Still no mental gymnastics, although I am starting to peak.
+:45 – Increase in sexual awareness – I now know what I’ll be doing next time with this chemical.
+1:00 – Definitely passed my peak. Decide to go for a walk. Phone rings, talking no problem.
+1:10 – Go for a walk.
+1:25 – Back from the walk. Too cold and navigating London traffic (even as a pedestrian) is too scary.
Effects have diminished considerably.
+1:45 – Just got off the phone talking to a mate about the trip. Post trip synopsis – nearly baseline now.
REFLECTION:
This is a strange experience. I was expecting an increase in associations, to generate new perspectives. I think this is a dosage reliant effect.
Visuals were not the typical bending/morphing variety. No form constants like lattice, filigree, tunnel, spiral, etc.
My visual field seemed expanded or as if I were viewing the world through a fish eye lens. This is a commonly noted effect of 4-AcO-DET.
Experience Reports are the writings and opinions of the individual authors who submit them.
Some of the activities described are dangerous and/or illegal and none are recommended by Erowid.

For networking and communication , I decided to go for Half-duplex serial communication between an Input and Output devices. Input device was Distance sensor and Output device was RGB led.
With help from Gautam and Mohit, I designed a Distance sensor board. I had earlier designed a distance sensor board in previous week but could not use it for networking since it did not have Rx/Tx for communication.
The first step was to design the board in Eagle. I took my old board and added Rx,Tx,VCC and GND pins. Over all the board had following components:
Next I checked if the board was working individually. For this I tried the following codes
First step was to put Rx,Tx,VCC and GND in the board developed for Input device.For output device, I used the board I made in previous week's assignment, which can be found here.
The code for LED was written to blink in different colours responding to input in the form of "0-1-2". However, when the code was run later using networking, it did not work. Then I realised that since we are already providing VCC in common pin, we need to give digitalWrite as "low" for the colour that we want to blink.
Hence, the code was corrected as below.
Next I used an FTDI cable and connected its Rx,Tx,VCC and GND to the input device board and the networking was established.
Next, to add more boards, I decided to add more values from my input device. The idea was to allow more boards to be connected. For this, one option is to call each board by giving different addresses from the computer, and the next option, which I chose, was to allow the input device to call for different boards and also define the colours of RGB led in the first board.My distance sensor code currently gave me values as 0-1-2. Here, value "0" would light up Red colour on the RGB board, "1" would light up Green and "2" would light up blue. So, again I changed the distance sensor code and increased its range to give an additional value "3". This value will give signal to light up the Led on "hello echo" board. Similarly the code can be modified to give additional values and signals can be given to additional boards as and when required.
Here is how the code looked like
I uploaded the code successfully to obtain 0-1-2-3 as values for different range of distances. I checked it on serial monitor first, before attaching the boards to the other board.
Next step was to write a code for "hell echo" led to light-up when it gets signal "3". Here is how it looked like.
Next step was to write a code for "hello echo" led to light-up when it gets signal "3". Here is how it looked like. The idea was to see the LED light up once you give the value "3" from the computer. Later on when all the boards are connected, this value will come from my input device.
I checked if my code was working individually. It would give me red, green, blue outputs for 0,1,2 respectively. Finally, since all individual codes were uploaded, I connected all 3 boards and FTDI, to check if my connections were working.

Group sues Buhari for extending Permanent Secretaries’ tenure
by Ade AdesomojuAde Adesomoju, Abuja
A civil society organisation, Advocacy for Human rights and equal Opportunity, on Wednesday, asked the Federal High Court in Abuja to nullify the elongation of the tenure of some retiring Permanent Secretaries by President Muhammadu Buhari.
The plaintiff joined as defendants, Buhari, the Secretary to the Government of the Federation, Head of the Civil Service of the Federation and the Attorney General of the Federation.
The group filed the suit marked FHC/ABJ/CS/1427/2019, through its counsel, Danshitta Saheed.
The plaintiff listed the concerned Permanent Secretaries as those deployed in the Federal Ministry of Interior, Federal Ministry of Women Affairs, Federal Ministry of Information and Culture, Federal Ministry of Agriculture and Rural Development, Ministry of Foreign Affairs, Federal Ministry of Water Resources and General Services Office in the Office of the Secretary to the Government of the Federation.
AHREO prayed, among others, for a declaration that by virtue Section 171 (2) of the Constitution of the Federal Republic of Nigeria 1999 (as amended), Buhari had no power or discretion to elongate or extend the term of office of the seven retiring Permanent Secretaries.
It equally asked the court to declare that the act of the President extending the tenure of the retiring Permanent Secretaries “is ultra-vires, null and void, illegal and of no consequence”.
It also sought a declaration that “the continuance being in office of the retiring Permanent Secretaries from the date they are due for retirement is illegal, unconstitutional and is against the spirit and later of Section 8 of Chapter 2, Rule 020810 of the Public Service Rules, 2008.”
The plaintiff also sought “a declaration that all acts or functions performed by the retiring Permanent Secretaries from the dates of their respective retirement be declares illegal, null and void”.
The group asked the court to issue an order of injunction restraining the retiring Permanent Secretaries from performing any act or functions of their respective offices.

4 Security Recommendation to Software Vendors
5 Recommendation to Cloud providers
OpenAttestation SDK is built based on Host Integrity at Startup (HIS) project developed by National Information Assurance research laboratory (NIARL) and Mount Wilson project by Intel to measure and report status of remote host platforms which contain a Trusted Platform Module (TPM).
The intended audiences of this document are Independent Software vendors (ISV), developers who are to integrate OpenAttestation SDK into ISV’s cloud management tools for product releases. Administrators who are to take advantage of remote host integrity checking capability for their cloud services by using ISV software packages which has OpenAttestation SDK integrated.
OpenAttestation SDK, by itself, is not a secured software or commercial ready product. It is expected that ISVs must enhance and integrate the SDK with their software stacks for security evaluation/validation cycles before production/distribution.
OpenAttestation SDK is software components to add cloud providers with capability of establishing hosts/clients integrity by remotely retrieve integrity reports saved in Hosts/Clients TPM.
The SDK is expected to be security enhanced, integrated with ISV’s cloud management software, and distributed/supported by ISV to cloud providers.
The integrated ISV software to be hosted and operated by cloud providers.
SDK does not add security enhancement to existing database or network infrastructure, rather it uses underlying infrastructure supported by ISVs and operated by cloud providers.
Attestation service is hosted by cloud providers, Hosts/Clients privacy is cloud providers or ISVs responsibility.
ISVs must follow industry security standards and recommendation to integrate OpenAttestation SDK with their software stack.
Cloud providers should follow industry security standards and recommendation to operate and maintain secured infrastructure.
Besides recommendation bellow, ISVs should follow industry security standards in integrating OpenAttestation into their software stacks.
OpenAttestation SDK exposing APIs, Integrity query API for management software to remotely query host(s) integrity and Whitelist API for administers to remotely setup/update good, know measurement data. Where these APIs should be access controlled from general users due to privacy and security purpose. To ensure access controls to APIs, ISV should perform following designs:
ISV should clearly document than a deployment should always setup web container’s 2-way SSL/TLS authentication between Access platforms and Attestation service in order to ensure controlled platforms can access to APIs. Fail to setup authentication, a cloud infrastructure’s privacy and security can be compromised.
ISV should work with Cloud provider to establish their credential control in accessing APIs. Note all the APIs requests to Attestation server has an authentication blob which enables ISV software to pass access credential to attestation service, which attestation service is only to pass to an ISV authentication specific validation service in SDK. It is ISV’s responsibility who integrates SDK should fully implement the validation service.
ISV should enhance HostAgent/TrustAgent installation package to be created into a secured smart media to keep attestation service keys within controlled, secured access environment.
Cloud providers should follow industry security standards in operates and maintain infrastructure.
Attestation infrastructure takes PrivacyCA approach to certificate Hosts TPM keys. Cloud providers should securely safe-keeping PrivacyCA and EKsigning Key pairs.
Attestation service installation:
Attestation service and management tools accessing API services are Root of Trust of overall cloud infrastructure -- Cloud provider must ensure these components are installed with underlying systems are in a trusted state.
Cloud provider must ensure the correct PrivacyCA certificate is installed into Appraiser.
Whitelist database must be kept in a secured, controlled environment.
HostAgent/TrustAgent, agent code to be installed into Hosts, installation must ensure:
Host is in a trusted state for Agent installation.
Agent must be installed by a trusted entity with auditable process.
EKsigningKey must not be installed into Host.


Devbootcamp Phase 0 Week 1
Sunday August 23 2015
My first week has been very enjoyable. I am already learning a ton of new information. This week I was introduced to Git and Github. Git uses a version control system that you download to your computer. Github is a open source online community that you can post your files to and have other people look at them and edit them. Version Control is another cool thing I learned about this week. Essentially it is just a great way to keep track of your progress with the use of different saved commits. These commits are like "screenshots" of your work and you are able to navigate back and forth through the commits. This is extremly helpful for fixing bugs in your code which can be hard to identify at times. Being able to work back and forth through the commits makes it eaiser to identify where your code took a turn for the worst. You can then start from that commit and just build off the previous code that you have entered.
Git also helps you keep track of your code by giving you theability to title your commits so that you are able to know exactly what you where working on at that point of time in your project. You should use Git Hub to store your code because its stored in the cloud. Meaning that you are able to access it anywhere that has an internet connection. This is useful for two reasons first being that god forbid your computer breaks you are still able to access your code. Second being that if multiple people wanted to look at your code you wouldn't have to spend the time to send it to each person individually you could just give them the link to access your code.


Brainstorm
Now that you have a How Might We question, it's time to brainstorm some ideas to try to solve for the question. Generating ideas by yourself can be fairly difficult if you are new to this process. Even experienced designers benefit from working in groups because typically the array of ideas generated in a discussion is far larger than when working alone. For this step, you will partner up with small groups to brainstorm ideas for each person's project. You will use the free Dropbox tool called Paper, to collaboratively contribute ideas to your group members projects.
Note: If there is a timezone issue, and your group can not find an agreeable meeting time, contact your instructor.
Note 2: If you have technical issues, please see "Solving technical issues" section.
View an Example Paper brainstorm session.
Materials and tools
- Sign up for a free account on https://paper.dropbox.com/
- Computer with microphone and steady Internet connection
- Video conference: Penn State Zoom
Roles and Rules
Discussion Rounds
- Team Leader: A Team Leader is randomly assigned and is responsible for coordinating the group's brainstorm session.
- The Team Leader will coordinate a meeting time and send out a video meeting link with the group.
- There will be one brainstorming round for each person in the group.
- Each member should access the Paper website ahead of the brainstorm session and locate the document's share link.
- Each round will focus on a different person's HMW question.
- Facilitator Role: For each round, the person currently in focus for the discussion will be the facilitator of the discussion, and is responsible for downloading their finished whiteboard and uploading the image to the Studio.
- The facilitator is responsible for keeping time.
- Responsible for downloading their own How Might We...? document in Word (docx) format.
- Spend about 10-15 minutes per round.
Brainstorming
- Quantity over quality. The goal is to generate as many ideas as possible.
- Defer judgement. Silly and outlandish ideas are just as useful as, and sometimes more exciting than, sensible ideas.
- Be positive. When building upon others' ideas, use "yes, and also" instead of "but" or "well." These small language nuances change the tone of the discussion to feel more supportive and inclusive.
- Focus. It's easy to derail a brainstorming session. If it happens, refocus on the task at hand.
- Simplify. If an idea takes two sentences to describe, try simplifying it to the core idea using as few words as possible.
Instructions
Before the brainstorm session
- Read the Roles and Rules.
- Access https://paper.dropbox.com/.

I've spent the past few years building and growing PATOS, a fashion brand that sells handcrafted Latin American footwear.
Today, it's normal to come across my sneakers on the shelves at J.Crew or in an NBC feature. But it wasn't long ago that I was struggling to reach my first 5 pairs of shoes sold.
So, how'd we get here?
It wasn't until I met a man named Rafael that I started to question why I have no idea who makes the shoes I wear.
Rafael is an Argentian artisan who makes shoes by hand. Every weekend, he hops in his red Toyota and drives an hour into Buenos Aires to sell his shoes at a local artisan fair.
The shoes are bright and eye-catching, with authentic Latin American textiles sourced from local suppliers covering them.
And while he's been making shoes by hand for 20 years, Rafael's only true customer base is the handful of locals and tourists who happen to walk by his shoe stand as they venture through the flea market.
While visiting my grandparents in Buenos Aires, I happened to come across Rafael's stand. And as I watched tourists crowd around in awe of his shoes, I had nothing but questions.
I mean, here was this guy who had an amazing skill, an inspiring story, and a beautiful product.
Why don't I see his shoes back home? Wouldn't people love to wear these knowing they're supporting Rafael? And why do I have no idea who makes the shoes I normally wear?
So I asked, and we talked for hours.
He started making shoes when he was 16 when he found out he had a son on the way. He spent decades becoming an expert at making shoes, only to find that he had no access to the international market that would love them.
So without much thought, I did what anyone would have done in that scenario. I asked Rafael if he would sell me fifty pairs of shoes to take home to the United States.
Two weeks later, I picked up the shoes from Rafael, stuffed them into my suitcase, and hopped on a plane back to Penn.
There began my bizarre, life-changing journey to start a global footwear brand called PATOS.
(This was underratedly one of the most pivotal moments of my life.)
In the three years since meeting Rafael, I've hired over 15 artisans across poor villages in Peru and Argentina to handcraft shoes and backpacks under safe working conditions with fair pay.
We've sold thousands of shoes across 15 countries, partnered with J.Crew, raised over $60,000 on Kickstarter.

Rafael continues still has his own PATOS collection – the Yoga Flats – to this day.

Six Essential Tips for Woodcarving
I'm by no means an expert woodcarver but have been practicing for long enough to notice the significance of certain aspects. The following points stand out, they can make the difference between satisfaction and utter despondency.
- Plan ahead
- Use good quality tools
- Sharpen well
- Support the workpiece securely
- Be aware of the wood's grain
- Be patient
They may seem obvious, but that's the big problem, these things are really easy to overlook. I'm going to print this list out and stick it on the wall, I suggest you do the same.
1. Plan ahead
Yeah, obvious. But specifically with woodcarving, it really does pay in the long run to devote plenty of time to planning. First there is making sure you've got all the tools and materials you're going to need (not forgetting superglue and band-aids for those unintentional cuts in work and fingers respectively). Even if you're lousy at drawing, rough sketches can not only focus your mind on the task ahead but also reveal potential problems ahead of time. There's little worse than spending hours working on something only to discover a silly oversight that means it won't work.
If you're making something fairly figurative, making a model in plasticine is a good idea. Any bits that look especially tricky can be tried out on a piece of scrap. Consider making a disposable prototype using cheap materials. Experiment, experiment, experiment.
If you're really lucky, there may be something you can copy from.
Don't forget the woodworker's maxim : measure twice, cut once.
2. Use good quality tools
Good quality essentially means steel that will hold an edge and a comfortable handle.
Nothing can be more frustrating than trying to work with bad tools. No matter how much effort you put in, however careful you are, you'll be lucky to get good results.
Good quality doesn't necessarily mean expensive. There are cheap sets available but beware, often the price is reflected in the quality - nasty bendy steel that won't stay sharp. Look for a respected maker's name (When buying new I personally favour Henry Taylor tools: no-fuss solid Sheffield ware, though there are lots of other good brands around, e.g. Pfeill, Two Cherries etc). While new gouges usually cost around Â£20 upwards each, second-hand ones can be found at a fraction of this price (junk shops, yard sales, obscure online shops, eBay). As long as there isn't too much pitting of the metal, even very rusty tools can be resurrected. Tools that have come from another carver's toolbox are likely to be good, whatever their age (if you see a personal name stamp on the handle, that's a win).
Smaller tools do tend to be less expensive, but bear in mind it's pretty straightforward to make your own from masonry nails using a blowtorch and hammer. With care the quality can be top notch.
What's more, it's much better to have two or three quality tools than dozens of poor ones. Virtually any carving can be done with a couple of tools. It may take longer than it would having racks of gouges available, but it's still possible, which it probably won't be with bad tools. Even if you have racks of gouges, you will tend to use three or four of them more than any other. It's often easier to make two cuts with a slightly suboptimal tool than look for the ideal one and make one cut.
3. Sharpen well
Yup, sharpen well, sharpen again and keep sharpening. The necessity of properly sharp tools cannot be overstated. They simply don't work properly unless they're razor sharp - literally. While the steel/temper of carving tools is usually a little less hard than shaving tools (to avoid destruction by bashing and enable easier resharpening), the required edge is very much in the same ball park.
It can be seriously tedious getting an fine edge back on a tool that hasn't been used for a long time. But the effort will be repaid by sheer pleasure when using it. Also, a little counter-intuitively, sharp tools are much safer than blunt ones because they allow you considerably more control and require less force. Not so likely to skid off into flesh. But take care if you've not used the particular knife before - treating a genuinely sharp knife as if it were a normally "sharp" one can easily result in injury (as I once discovered when I borrowed a knife off a chef to cut an orange and it slid gracefully through the orange and continued effortlessly through my palm).
Not strictly relevant to sharpening but also on the subject of safety: you've probably heard the one about always cutting away from the body. With woodcarving this is still a good idea, especially if you're new to it, but not the whole story. It doesn't matter if parts of you are in the line of fire as long as you are in complete control of the cut. That's what to aim for. I've not personally tried using leather/Kevlar/chain mail safety gloves, again they're probably a good idea if you're new to carving. But I suspect long term they're probably best avoided, because of the psychology of risk compensation - if you feel safer, you're more likely to take risks, and that suggests decreased control. Having said all that I must also say that although eye protection isn't usually necessary while carving it's absolutely essential when using power tools. (I'm short-sighted so my glasses are my usual protection, but I'll still pop on the goggles if I'm grinding or whatever).
It's usually best to try and sharpen all the gouges and knives you expect to use during a carving session before you start, give them a wipe to remove any traces of stone and also wash your hands. Once a tool is sharp, it can be kept sharp by briefly stropping it periodically during the carving session (say after every 10 or 15 minutes of use of that particular tool).
At the end of a carving session it's a good idea to wipe the tools with an oily rag and remember to keep them in a dry place.
4. Support the workpiece securely
As well as control over the cutting tool, you need control of the thing you are cutting. Traditionally the woodcarver would work standing at a heavy-duty wooden bench with their work either held in chops, a leg vice or on a screw. While these approaches are always options, all that really matters is that the piece you're working on isn't going anywhere. This can be achieved using anything from a carpenter's bench and vice, a solid tray on your lap with ad hoc wedges or a thick piece of plywood on the kitchen table and a handful of clamps.
A vice used in conjunction with wedges in bench dog holes makes a good solution to holding flat work.
If the work is small or an unusual shape, it may be possible to knock together a quick-and-dirty holding jig from bits of scrap.
Modern screw clamps are really cheap and can work perfectly well. Every time you visit a tool shop or hardware store, pick up a couple more. If the work you're carving is coming from a big piece of wood, you can probably leave some of the surplus attached to help with clamping. Even if you can't clamp to the work directly, you may be able to screw it to a board that you can clamp.
You can never have too many clamps.
5. Always be aware of the wood's grain
The grain is probably the most important characteristic of a piece of wood in practical terms. How the blade of a gouge or knife is angled relative to the grain will determine how the cut proceeds. Cuts in the direction of the grain take less effort, but have a tendency to slip out of control. Cuts straight across the grain are harder work but aren't so likely to surprise. However most cuts will be made between these extremes, at a diagonal at some angle.
The grain can be very deceptive. Sometimes it looks like what's needed is say, to simply use a V tool to cut out a line or curve to outline a form. But although the grain might be running in a favourable direction for one side of the V, on the other side it's running exactly wrong, and the result when you try it is a nasty tear.
In fact quite often when you'd ideally like to make a single, possibly deep groove the grain on one side is angled in a way likely to cause problems. One trick that can help in such situations is to cut a line vertically into the wood down the middle of where you want the groove to go, then make two cuts to form the groove - one in each direction.
Actually, think twice before using the V tool would make a good candidate for a 7th tip, a lot of the times when it seems like the best tool for the job it isn't. What's more it's the hardest to sharpen, so best left alone unless it's really called for. Ok, if you're doing a relief, the V (also known as parting) tool is an obvious choice for outlining. In these circumstances the groove it makes acts as a marker and stop cut (see below) for where the ground will be as well as a something of a stop cut when you come to setting in (making vertical cuts around the exact outline of the relief). But for both these purposes a tight gouge or veiner, say a No.10, 1/4" can do the job equally well. Just consider it, all I'm saying...
The stop cut is your friend. In its basic form you make a vertical incision across where you want your planned cut to end at the depth you're aiming for, so the wood won't split beyond when you make the actual cut. There are many variations of this basic technique. For example, say you were carving some letters in relief, and want to get the background down immediately around the letters. It may be useful not only to make a vertical stop cut around where the edge of the letters will be, but also gouge a groove further away from the letters than the cut you really want to make. This way there's a kind of fire break on either side of your planned cut, it's much more likely to go the way you want it to.
While some woods can be easy-going, fairly consistent across different directions (e.g. basswood, boxwood) others can be really obstinate and prone to split (e.g. some oak, chestnut). Ideally you should experiment with offcuts of the piece of wood you're going to be carving, failing that start the work with really gentle cuts until you get a feel for how it responds.
6. Be patient
No matter how slow you feel you are proceeding, you're very unlikely to get better results by trying to speed up. A true cliche : more haste less speed.
Generally it is better to make a few well-placed cuts rather than a lot of little ones, it's more efficient and the result is usually more pleasing. However unless you're pretty sure a particular cut is going to work, the shave-shave-shave option is preferable to one big screw-up.
Mistakes in themselves may be undesirable, best avoided, but in the great scheme of things they're positive. Making mistakes is a great way of learning. There's always next time.
If you find yourself starting to make mistakes, take a break.
Some final thoughts
Aim for perfection, but be happy if you achieve mediocrity. If you've made something that didn't exist before, no matter how shabby, that in itself is a significant achievement.
Oh yeah, and never give up. Well actually, give up if you want to, it's entirely up to you.


since I'm a huge fan of customization in generell I came across the idea of having a dark/greyish Materialdesign theme. Let me know if you like this suggestion :)

For BF3 or BF4 Battlelog?

I would say both BF3 and 4 but that'd be too much as a request. So BF4 would be totally fine :)

mhh noo. i dont like this idea.. and won't create something like.
the way which internet goes is lite, simple design, bright colors and no "materials".
but maybe somebody likes your idea and will create a theme :-)
hope you'll find something nice :-) why don't you create a own theme which you could share? :-D

If I had the knowledge I wouldn't ask you guys.
Maybe I'll find the time to learn everything but right now I'm too busy :(

Now I'm converting my Hardline theme on BF3 Battlelog. And when I will do it, perhaps, will be engaged in your.

this is a bit OT, but what happened to the dark wood option in the black shadow theme? i fell in love with that and now is no more there...
