There are times where it's desirable to load fragment views and/or
models after some action has taken place. In this case, one of the HTTP
Methods/verbs can be used whenever one or more DOM events are
received. thymus.js tries to conform to RESTful
conceptual design patterns. So naturally, wiring fragmented
model/views into thymus.js requires the use of guidelines set
forth by the established HTTP methods. Determining how model
data and/or views are transfered to a page is determined by
the type of HTTP method verb used on one of the corresponding
data-thx-*VERB*
siphon attributes; where *VERB* would be replaced
with one of the following HTTP method verbs (e.g.
data-thx-get
):
From this point on we will refer to
data-thx-*VERB*
as a siphon attribute to reference the entire suite of
supported thymus.js event driven HTTP method verb attributes.
siphon attributes should reside on the node where the DOM
event will be triggered. The semantics for siphon attribute
are separated into multiple facets that control behavior:
data-thx-*VERB*
$.on(event,
...);
registrations, there is one special case that thymus.js
will pickup regardless of the element that the siphon
attribute is defined on. A
load
event will cause thymus.js to automatically process the
fragment when the page or fragment first loads provided that
loading has not been deferred. This type
of loading is very similar to the
short-hand version, but allows for additional siphons to be
declared to permit more control over how fragments are handled.
data-thx-*VERB*-params
data-thx-*VERB*-path
data-thx-*VERB*-result
function
that will handle the result. Values can be separated by a "::"
to indicate which event within the event siphon the
value corresponds to. When a fragment result contains view
content or is XML model content the result siphon
will be used to select the portion of the fragment result that
will be used for insertion into the DOM. When the fragment result
contains model content that is not XML the result
siphon can either be omitted to use the entire fragment result or
contain a function
that
will manually handle selecting the portion of the fragment that
will be included in the DOM (e.g. using a 3rd party library to
handle the selection- like json:select()).
See the fragment siphons section
for more details on how result siphons use JQuery
selectors.
data-thx-*VERB*-dest
data-thx-*VERB*-type
window.open
for
HTTP get calls or a dynamic form submission for all other supported HTTP verbs. Types of
this nature will only use the path siphon and parameter
siphon (which is optional).data-thx-*VERB*-target
_blank|toolbar=no,width=190,height=190|true
). See the fragment siphons
section for more details on how target siphons use JQuery
selectors. Valid values are:
data-thx-*VERB*-agent
Typlically, navigating to other pages can be acomplished by using
links that contain an
href
or a submit
button
wrapped in a
form
. That may suffice in some situations. However, in other instances,
there may be a need to dynamically build the URL contained in the
href
and/or
action
or may need to be triggered outside a form or on an element other
than a link or submit button. There also may be a need to
dynamically build parameters that will be sent to the server that
may or may not reside within a form. Sure, adding some JavaScript
could easily solve the problem, but wouldn't be better to allow
JQuery selectors to do the work for us by building the URL parts and
parameters by siphoning them from other DOM elements? Not
only does that allow URLs for an application to be centralized, it
also allows them to be automatically built from user input that can
be scatterd throughout the page! It can even pull parameters from
attributes and node text! What if we were to tell you that this and
many other features can be done without a single line of JS? All
that is required is that the element contain a few siphon
attributes. First, an event siphon will need to declared
that will define the event(s) that will trigger the call. Secondly,
a path siphon needs to be defined to give direction to the
process. The final attribute that will need to be defined is a
synchronous destination type siphon that will specify that a
full-page transfer will be performed. There is no target
siphon so the operation will occur in the current window/frame.
Also, an optional parameter siphon attribute can be used if
there are any parameters that need to be passed. Here's an example
that illustrates a full page update that dynamically siphons
the passed parameters using JQuery (see siphon
resolvers for more details on how to construct path siphons):
<button type="button" class="btn btn-primary" data-thx-get="click" data-thx-get-path="?{#globalLoginPath}" data-thx-get-type="sync|transfer" data-thx-get-params=".simple-nav-params :input"> Goto Sign In</button> <input id="globalLoginPath" type="hidden" value="login" />
 <input type="text" class="form-control" name="simpleNavParam1" placeholder="Enter text to send as parameter 1" />  <input type="checkbox" class="simple-nav-params" name="simpleNavParam2" /> Param 2   <input type="radio" name="simpleNavParam3" value="radio 3" /> Param 3 (radio 1)   <input type="radio" name="simpleNavParam3" value="radio 2" /> Param 3 (radio 2)  <select name="simpleNavParam4" class="form-control" multiple="multiple"> <option value="option 1">Param 4 (option 1)</option> <option value="option 2">Param 4 (option 2)</option> </select> <input type="range" name="simpleNavParam5" min="1" max="100" />

A self-targeting asynchronous transfer is a node in which defines an event siphon, a path siphon and any other pertinent siphon attributes. The difference is that it does not define a destination siphon. In this case the destination siphon will default to the node where the siphon attribute is defined. Consider the following:

 ...

User Data:

 Click to load next user...

User Data:

 Click to load next user...
 ...

User Data:

 Click to load next user...
 ...

 ...

<button type="button" class="btn btn-primary" data-thx-get="click" data-thx-get-path="frags/user/user1" data-thx-get-result="[class^="thymus-user"]"> Run</button>
In a similar fashion a self-targeting asynchronous transfer can be replaced rather than included:

 ...

User Data:
 <button type="button" data-thx-get="click" data-thx-get-path="path/to/user" data-thx-get-result=".user-detail" data-thx-get-type="replace"> Load User </button>

User Data:

 ...

<button type="button" class="btn btn-primary" data-thx-get="click" data-thx-get-path="frags/user/user1" data-thx-get-result="[class^="thymus-user"]" data-thx-get-type="sync|replace">Run</button>
The most granular of the DOM event driven behaviors is one that defines a destination siphon. The destination siphont tells thymus.js where the returned fragment should be placed. Following the previous trend of examples...

 ...

 <button type="button" data-thx-get="click" data-thx-get-path="path/to/user" data-thx-get-result=".user-detail" data-thx-get-dest="#userDest">Load User</button>
 Users:

 <button type="button" data-thx-get="click" data-thx-get-path="path/to/user" data-thx-get-result=".user-detail" data-thx-get-dest="#userDest">Load User</button>
 Users:
 ...

User Data:
 <button type="button" data-thx-get="click" data-thx-get-path="path/to/user" data-thx-get-result=".user-detail" data-thx-get-dest="#userDest">Load User</button>
 Users:
 ...

 ...

<button type="button" class="btn btn-primary" data-thx-get="click" data-thx-get-path="frags/user/user1" data-thx-get-result="[class^="thymus-user"]" data-thx-get-dest="#userDest2">Run</button>
An update siphon attribute works similar to a include
siphon attribute except it will remove any prior
fragment insertions made before appending the fragment results. In
the example above, that would mean any
.user-detail
under
userDest
would get replaced with the current
.user-detail
result.
<select id="demoDomUpdateSel" data-thx-get="load :: change" data-thx-get-path="frags/user/?{#demoDomUpdateSel}" data-thx-get-result="[class^="thymus-user"]" data-thx-get-type="async|update" data-thx-get-dest="#userDest3"> <option value="user1">John Doe</option> <option value="user2">Jane Wayne</option> <option value="user3">Richard Roe</option> </select>

Each of the siphon attributes can contain multiple
events separated by a "::" within a single event
siphon. For instance, a
data-thx-get="click :: keyup"
can be defined on a node that will register a thymus.js
listener event on a
click
and
keyup
event. Each event defined within an event siphon will
correspond to any other siphon attributes with the same
HTTP verb that may be defined on the node at the same position. If a
siphon attribute does not have a value for the given event
siphon's event, then the last parameterized siphon value will be
used. Consider the following:
<input type="text" data-thx-get="click :: keyup" data-thx-get-path="frags/user/user1 :: frags/user/user2" data-thx-get-result="[class^="thymus-user"]" data-thx-get-dest="#userMultiEvt1 :: #userMultiEvt2" />
User 1

User 2

When the text input receives a
click
event
frags/user/user1
is called and the result is caputred via the JQuery selector
[class^="thymus-user"]
and includes (default) the results into the destination captured
from the JQuery selector
#userMultiEvt1
. Every time a
keyup
event is received
frags/user/user2
is called, the result is captured via the JQuery selector
[class^="thymus-user"]
and is included within the destination captured from the JQuery
selector
#userMultiEvt2
.
Nodes that need to trigger similar transfers can become redundantly verbose. That's why thymus.js provides a concept of an agent. An agent can be thought of as a node that will provide a service on behalf of other node(s). There is little difference between a node with the typical siphon attributes and an agent. So, any node can become an agent without having to explicitly declare it as an agent. However, other node(s) can add an agent siphon that will contain a JQuery selector that will select the node(s) that will act as an agent. This causes thymus.js to look at the agent node(s) for any siphon attributes that are missing from the node where the agent siphon is defined. When the JQuery selector returns more than one node, the first node that contains the missing siphon attribute will be used until all siphon attributes are found or all of the selected agents are exhausted (whichever occurs first). An agent itself can define it's own event siphon if so desired, but it is optional. Lets take a look at an example where we might want to use an agent.

  <input type="radio" name="userDest2GrpOpts" value="user1" data-thx-get="load :: change" checked="checked" data-thx-get-agent="#userDest2Grp" /> Include User1   <input type="radio" name="userDest2GrpOpts" value="user2" data-thx-get="change" data-thx-get-agent="#userDest2Grp" /> Include User2   <input type="radio" name="userDest2GrpOpts" value="user3" data-thx-get="change" data-thx-get-agent="#userDest2Grp" /> Include User3

A short-hand for loading fragments which is equivalent to a event
siphon with a
load
event and a separate path siphon attribute. Instead of two
attributes, the short-handed version combines the path siphon
and result siphon into one attribute separated by a "::"
(the separator can be overridden using the
data-thx-separator
attribute on the thymus.js script definition or programmatically by passing the
appropriate option parameter). It also infers the destination
type siphon based upon the short-hand attribute used. The
short-handed version can be used as either a replacement or
inclusion anywhere a
data-thx-replace
or
data-thx-include
siphon attribute is found throughout the document (including
within a fragment itself). It's use is limited to the path
siphon and result siphon defined within it and will not use
any other siphon attributes that may be defined on the node.
Examples can be found under the fragment types
section.
The following example demonstrates how to automatically load a
fragment using a
data-thx-replace
attribute:

 ...

 ...

Of course, we could have also used a
data-thx-include
instead of
data-thx-replace
which would have appended the fragment rather than replacing the
placeholder:

 ...

 Top Nav

 Top Nav
 ...

path siphons can also refer to fragments that exist in the
same page where the path siphon resides by using
this
or omitting the path altogether (e.g.
data-thx-include="::.my-inline-frag"
). Only use this approach when the fragment's result siphon is
not referencing nodes that reside in other fragments.

PLease post the following review to the newsgroup
Lock, Stock And Two Smoking Barrels **1/2
rated R starring Jason Flemyng, Dexter Fletcher, Nick Moran, Jason Statham, Steven Mackintosh, Vinnie Jones, Sting written and directed by Guy Ritchie
Guy Ritchie's new British import LOCK, STOCK AND TWO SMOKING BARRELS is a film that can be either loved, loathed or both. LOCK, STOCK tells the story of 4 criminals who pool their money into a rigged game of poker. They even lose some money that was lent to them by local "porn king" "Hatchet" Harry (P.H. Moriarty). He gives them a week to retrieve the money. From that point on, the film goes wild, twisting plot points around your head quicker than you can say "What's going on?" LOCK, STOCK would be confusing as an American film, but it is British, which makes it all the more confusing because of the unidentifiable slang and accents. Throughout the film, I could not distinguish one character from the other. In my opinion, LOCK, STOCK needs maybe 3 viewings to be fully enjoyed. One to recognize Guy Ritchie's direction, which is at once derivative and dazzling. Two to in some way digest some of the dialogue being spoken. And three in order to try to understand each plot point. But sadly, most people, like me, would rather just see a film once.
Despite its shortcomings, LOCK, STOCK is a fun-filled caper, and it has more energy and hipness than most of our violence-laden action pictures. LOCK, STOCK was supposedly a huge hit in England, and it's not hard to see why. I only wish that the filmmakers and taken the approach that Artisan Films did to MY NAME IS JOE by subtitling the English-language film. Another one of the film's flaws is its excessive use of drum & bass music between scenes. At the beginning of the movie it was hip, but towards the end it becomes repetitive. There is really no message in LOCK, STOCK, and it never comes close to reaching the poetic display of RESERVOIR DOGS, but if you're looking to spend a free afternoon at the movies, this should provide some entertainment as long as you bring a dictionary. (Oh yeah, I forgot to mention that Sting has a small role)

LSD |
(blotter / tab) |
My first experience with LSD occurred on June 22, 2001. It was with my friends L and G and A.
At 12 PM, I put the single blotter tab in my mouth. I was told it was triple dipped. We walked to the train station for about 20 minutes. I was very excited. I was ready for my trip. We got on the train and I started feeling a little euphoric. I felt simply good. I think L smoked while we waited for the train and I didnít really feel anything. We got to where G lives and L smoked again on the stairs down to the street and there I was twirling around and around, and I was having fun. Then we walked to Gís, this walk I donít actually remember. We went up to Gís and I got into her room and I looked at the posters and they seemed to be coming at me. Perhaps this is how objects appear to be breathing, yet they were more coming at me, it was amazing to see this.
G turned on the Chocolate Starfish Limp Bizkit song I like, Hot Dog something, and it was so good, great to listen to. We then went to the library, and on the way there, L smoked a joint. It was really annoying listening to L and G argue, I was a little pissed, but I got over it looking at the surroundings, which were actually rather boring. L got high, but not very high. Although she found it humorous poking me, because I felt funny, very, very funny and I was laughing at everything. When she poked me, I felt like I was being tickled, but mildly.
When we got to the library, G and A went in and me and L stood outside. L smoked and I was looking around. I saw this beautiful guy who looked exactly like this guy I always thought was hot. Iím sure he was real, but maybe he looked like him because of my state of mind. It was there that I realized that my sight was incredibly clear, far clearer than usual. We continued from the library to this park.
We walked past the park where L smoked the roach of the joint she was smoking and I was walking around and thinking and my thoughts appeared ambiguous. They were a paradox. I looked at something and I wasnít sure if that which I looked at was what I was actually looking at and the realization that what Iím looking at is what I think it is made me very happy. We walked around and soon crossed the street. I noticed that holes in space time were forming in the building we were near. The building appeared to be covered in black spots void of anything, yet it wasnít.
We walked down a block filled with trees and houses and it was dark there. It was there that I began to feel some of the more apparent effects of the acid. There were body sensations, like something was coming at me. As we turned to go to another block, I started to walk in the way that I remembered M, this guy Iíve liked for a while now used to walk. And I believed M was like a God and I said to myself that I am like God because I was walking like M. L and G thought it would be funny to make me paranoid by making me believe there was a huge bee on my bookbag, and it worked, I got very scared but I let go of the fear. We were walking to this girl Jís house and I looked at the street sign and I saw 6th street, and I got scared, I thought they were taking me away to kill me, I actually believed that to be happening, and I asked them about it.
They told me we were on 8th street, and I looked again and saw that it was true. We got to Jís house and I was reaching the peak. I started looking at my hand while we were in front of her door and I could see the blood vessels and the veins and I put on my music and it did sound very different. I felt like I was moving everywhere while I was standing still. When I closed my eyes, although, I saw no visuals of any kind, but when I opened them, everything was coming at me. We left Jís and we were walking to this park, and I was listening to music but then I stopped because it was uncomfortable. This was Visual Audio Sensory Theater, and I didnít enjoy it. I was walking and L and G were arguing.
I think and then they started saying things and I wasnít sure if it was real. They made me very scared and I spit out my tab and fell to my knees crying. They apologized and asked if I was okay and suddenly everything became ok and I was feeling great. The bulk of the heavy fear had passed and we went to the park. I was amazed at how different the park was from the way I remembered it to be. It was huge, yet itís not. We sat down on a bench and planned the last day of school. I looked at Lís bracelet and I held it in my hands. It appeared to be getting wider and longer yet I knew it wasnít.
I looked around and I looked at one of the pigeons. Its feathers gained a unique blue color. It was the bluest pigeon I had ever seen. There were spots of color everywhere. Gís skin looked very bright and illuminated, as did Lís and for the first time I realized how bright Lís eyes are. I looked at everything and A tried to make me paranoid by wanting my to pet the squirrels but I knew they were rabid, or may have been.
A Jewish woman passed by with her three kids, one in a stroller. I looked at her eyes and they were shining green. The green was everywhere. I looked at the eyes of her children and they were the same. I was very frightened.
While in the park, sitting down, I felt euphoria, my body felt very good everywhere. I was enjoying it all. We left and L called her mom and it was a little hard to be standing up. As I was walking, I felt very light and I said, ďWhat kind of a moron thinks they can fly on acidÖI can!!!!!Ē I jumped up and falling down didnít feel like it, it felt like I was still walking. So we got to Gís house and we were sitting outside and I felt the acid rising and falling gradually. I didnít want it to go away. When I put my hands behind my back, it was weird, like they were no longer a part of me, yet they still were.  She was like, in a few years, youíll know. I found it mean, as in I thought she was very homophobic, but at the same time I didnít feel threatened.
I was sitting there and me and L were talking about how we need to try other drugs. And I observed the trailing phenomenon on my hand. It was interesting. Lís parents arrived and we all got in. I didnít want to look at them and L was sitting there singing the sesame street on marijuana song. Her parents were so busy fighting that they didnít even notice. That was it, I realized thatís what fucks L up a lot, and she wants attention. At that moment I could almost cry.
We were driving and I was looking out the window, and I couldnít tell where we really were, yet I could, yet I couldnít. We got to her house and I walked up the stairs and I lied down on her bed and I looked at her posters. It was then that I looked at a picture of Marilyn Mansonís arm and saw hair on it and I realized that Manson is human. It struck me that I thought of him as something other than human, but he is. It was cool to realize it.
We later watched Moesha (for the first time in my life) and it was hilarious to watch it without sound because I could make it all up in my head. I thought that this episode was about facing racism in school, and it really wasnít. It was fascinating to watch it. TV on acid is fun. I ate some candy and oh my god, it was delicious. I enjoyed it.
Soon after I went home, I was driven and I made it home and I has hyper and great all night. I talked to people and listened to music and felt excellent, while enjoying some cute closed eye visuals. I looked at some of the classical period paintings in my room and they seemed to be moving. The horses and carriages of 19th century Paris came alive. The letters on my screen seemed to be floating off the screen, yet a second later they werenít.
I watched the season finale of Buffy the vampire slayer in the dark and it seemed so much better. In this episode, there was a bright dimensional portal which seemed to be illuminating itself everywhere.
I went to sleep late and at 1:30 or so, I have to be honest and say, I jerked off. It was amazing to orgasm. I saw very, very, very interesting visuals in the dark. They were tunnelling and just surfaces. It was so cool. I experienced the very threshold of LSD and it was amazing. I wish I had gotten into conversation more and I need to do it again. Now that I look back, I feel like I was holding back the whole experience because I was too scared to let it out. I canít imagine the beauty I would have beheld in the world around me if I had let it out.

alter8r.Rd
alter8r()
is the keystone function that the package is based on. It takes the input values of what an NMR spectrum's signal and noise values are and how many scans it took to produce them and returns the number of scans need to be performed by an NMR to produce the desired signal to noise ratio as defined in the goal arg.
alter8r(sig, noi, goal, ns, r2)
| sig | The signal |
|---|---|
| noi | The noise |
| goal | The target signal to noise |
| ns | The number of scans used to create the provided signal and noise values |
| r2 | Arguments passed to embedded roundr function. See roundr help for details. |
The number of scans (rounded based on the input arguments from r2) necessary to achieve the goal signal to noise
The signal to noise ratio of an NMR spectrum shows how large the signal is compared to that of the noise. Adjusting the number of done by an NMR spectrometer can allow you to alter this signal to noise ratio.
The relationship between number of scans and signal to noise ratio is based around a square root so if one wants to increase the the signal to noise ratio by a factor of two, they must increase the number of scans by a factor of 4.
alter8r()
takes this relationship into account to calculate the number of scans needed to be performed on a sample to produce a spectrum with a certain signal to noise and is the value returned by the function.

Description
HPL_spreadN
spreads the local array containing local pieces of U, so
that on exit to this function, a piece of U is contained in every
process row. The array IPLEN contains the number of rows of U, that
should be spread on any given process row. This function also probes
for the presence of the column panel PBCST. In case of success, this
panel will be forwarded. If PBCST is NULL on input, this probing
mechanism will be disabled.
Arguments
PBCST (local input/output) HPL_T_panel *
On entry, PBCST points to the data structure containing the
panel (to be broadcast) information.
IFLAG (local input/output) int *
On entry, IFLAG indicates whether or not the broadcast has
already been completed. If not, probing will occur, and the
outcome will be contained in IFLAG on exit.
PANEL (local input/output) HPL_T_panel *
On entry, PANEL points to the data structure containing the
panel (to be spread) information.
SIDE (global input) const enum HPL_SIDE
On entry, SIDE specifies whether the local piece of U located
in process IPMAP[SRCDIST] should be spread to the right or to
the left. This feature is used by the equilibration process.
N (global input) const int
On entry, N specifies the local number of columns of U. N
must be at least zero.
U (local input/output) double *
On entry, U is an array of dimension (LDU,*) containing the
local pieces of U.
LDU (local input) const int
On entry, LDU specifies the local leading dimension of U. LDU
should be at least MAX(1,IPLEN[nprow]).
SRCDIST (local input) const int
On entry, SRCDIST specifies the source process that spreads
its piece of U.
IPLEN (global input) const int *
On entry, IPLEN is an array of dimension NPROW+1. This array
is such that IPLEN[i+1] - IPLEN[i] is the number of rows of U
in each process before process IPMAP[i], with the convention
that IPLEN[nprow] is the total number of rows. In other words
IPLEN[i+1] - IPLEN[i] is the local number of rows of U that
should be moved to process IPMAP[i].
IPMAP (global input) const int *
On entry, IPMAP is an array of dimension NPROW. This array
contains the logarithmic mapping of the processes. In other

Most conventional calculators, both the specialized hardware and software varieties, represent numbers using fairly conventional machine floating point arithmetic. Each number is stored as an exponent, identifying the position of the decimal point, together with the first 10 to 20 significant digits of the number. For example, 1/300 might be stored as 0.333333333333x10-2, i.e. as an exponent of -2, together with the 12 most significant digits. This is similar, and sometimes identical to, computer arithmetic used to solve large scale scientific problems.
This kind of arithmetic works well most of the time, but can sometimes produce completely incorrect results. For example, the trigonometric tangent (tan) and arctangent (tan-1) functions are defined so that tan(tan-1(x)) should always be x. But on most calculators we have tried, tan(tan-1(1020)) is off by at least a factor of 1000. A value around 1016 or 1017 is quite popular, which unfortunately doesn't make it correct. The underlying problem is that tan-1(1017) and tan-1(1020) are so close that conventional representations don't distinguish them. (They're both 89.9999… degrees with at least fifteen 9s beyond the decimal point.) But the tiny difference between them results in a huge difference when the tangent function is applied to the result.
Similarly, it may be puzzling to a high school student that while the textbook claims that for any x, sin(x) + sin(x+π) = 0, their calculator says that sin(1015) + sin(1015+π) = -0.00839670971. (Thanks to floating point standardization, multiple on-line calculators agree on that entirely bogus value!)
We know that the instantaneous rate of change of a function f, its derivative, can be approximated at a point x by computing (f(x + h) - f(x)) / h, for very small h. Yet, if you try this in a conventional calculator with h = 10-20 or smaller, you are unlikely to get a useful answer.
In general these problems occur when computations amplify tiny errors, a problem referred to as numerical instability. This doesn't happen very often, but as in the above examples, it may require some insight to understand when it can and can't happen.
In large scale scientific computations, hardware floating point computations are essential since they are the only reasonable way modern computer hardware can produce answers with sufficient speed. Experts must be careful to structure computations to avoid such problems. But for "computing in the small" problems, like those solved on desk calculators, we can do much better!
The Android M Calculator uses a different kind of computer arithmetic. Rather than computing a fixed number of digits for each intermediate result, the computation is much more goal directed. The user would like to see only correct digits on the display, which we take to mean that the displayed answer should always be off by less than one in the last displayed digit. The computation is thus performed to whatever precision is required to achieve that.
Let's say we want to compute π+⅓, and the calculator display has 10 digits. We'd compute both π and ⅓ to 11 digits each, add them, and round the result to 10 digits. Since π and ⅓ were accurate to within 1 in the 11th digit, and rounding adds an error of at most 5 in the 11th digit, the result is guaranteed accurate to less than 1 in the 10th digit, which was our goal.
This is of course an oversimplification of the real implementation. Operations other than addition do get appreciably more complicated. Multiplication, for example, requires that we approximate one argument in order to determine how much precision we need for the other argument. The tangent function requires very high precision for arguments near 90 degrees to produce meaningful answers. And so on. And we really use binary rather than decimal arithmetic. Nonetheless the above addition method is a good illustration of the approach.
Since we have to be able to produce answers to arbitrary precision, we can also let the user specify how much precision she wants, and use that as our goal. In the Android M Calculator, the user specifies the requested precision by scrolling the result. As the result is being scrolled, the calculator reevaluates it to the newly requested precision. In some cases, the algorithm for computing the new higher precision result takes advantage of the old, less accurate result. In other cases, it basically starts from scratch. Fortunately modern devices and the Android runtime are fast enough that the recomputation delay rarely becomes visible.
This form of evaluate-on-demand arithmetic has occasionally been used before, and we use a refinement of a previously developed open source package in our implementation. However, the scrolling interface, together with the practicailities of a usable general purpose calculator, presented some new challenges. These drove a number of not-always-obvious design decisions which briefly describe here.
We would like the user to be able to see at a glance which part of the result is currently being displayed.
Conventional calculators solve the vaguely similar problem of displaying very large or very small numbers by using scientific notation: They display an exponent in addition to the most significant digits, analogously to the internal representation they use. We solve that problem in exactly the same way, in spite of our different internal representation. If the user enters "1÷3⨉10^20", computing ⅓ times 10 to the 20th power, the result may be displayed as 3.3333333333E19, indicating that the result is approximately 3.3333333333 times 1019. In this version of scientific notation, the decimal point is always displayed immediately to the right of the most significant digit, and the exponent indicates where it really belongs.
Once the decimal point is scrolled off the display, this style of scientific notation is not helpful; it essentially tells us where the decimal point is relative to the most significant digit, but the most significant digit is no longer visible. We address this by switching to a different variant of scientific notation, in which we interpret the displayed digits as a whole number, with an implied decimal point on the right. Instead of displaying 3.3333333333E19, we hypothetically could display<PHONE_NUMBER>3E9 or<PHONE_NUMBER>3 times 109. In fact, we use this format only when the normal scientific notation decimal point would not be visible. If we had scrolled the above result 2 digits to the left, we would in fact be seeing ...33333333333E7. This tells us that the displayed result is very close to a whole number ending in<PHONE_NUMBER>3 times 107. Effectively the E7 is telling us that the last displayed digit corresponds to the ten millions position. In this form, the exponent does tell us the current position in the result. The two forms are easily distinguishable by the presence or absence of a decimal point, and the ellipsis character at the beginning.
Normally we expect calculators to try to round to the nearest displayable result. If the actual computed result were 0.66666666666667, and we could only display 10 digits, we would expect a result display of, for example 0.666666667, rather than 0.666666666. For us, this would have the disadvantage that when we scrolled the result left to see more digits, the "7" on the right would change to a "6". That would be mildly unfortunate. It would be somewhat worse that if the actual result were exactly 0.99999999999, and we could only display 10 characters at a time, we would see an initial display of 1.00000000. As we scroll to see more digits, we would successively see ...000000E-6, then ...000000E-7, and so on until we get to ...00000E-10, but then suddenly ...99999E-11. If we scroll back, the screen would again show zeroes. We decided this would be excessively confusing, and thus do not round.
It is still possible for previously displayed digits to change as we're scrolling. But we always compute a number of digits more than we actually need, so this is exceedingly unlikely.
Since our goal is an error of strictly less than one in the last displayed digit, we will never, for example, display an answer of exactly 2 as 1.9999999999. That would involve an error of exactly one in the last place, which is too much for us.
It turns out that there is exactly one case in which the display switches between 9s and 0s: A long but finite sequence of 9s (more than 20) in the true result can initially be displayed as a larger number ending in 0s. As we scroll, the 0s turn into 9s. When we immediately scroll back, the number remains displayed as 9s, since the calculator caches the best known result (though not currently across restarts or screen rotations).
We prevent 9s from turning into 0s during scrolling. If we generate a result ending in 9s, our error bound implies that the true result is strictly less (in absolute value) than the value (ending in 0s) we would get by incrementing the last displayed digit. Thus we can never be forced back to generating zeros and will always continue to generate 9s.
Internally the calculator essentially represents a number as a program for computing however many digits we happen to need. This representation has many nice properties, like never resulting in the display of incorrect results. It has one inherent weakness: We provably cannot compute precisely whether two numbers are equal. We can compute more and more digits of both numbers, and if they ever differ by more than one in the last computed digit, we know they are not equal. But if the two numbers were in fact the same, this process will go on forever.
This is still better than machine floating point arithmetic, though machine floating point better obscures the problem. With machine floating point arithmetic, two computations that should mathematically have given the same answer, may give us substantially different answers, and two computations that should have given us different answers may easily produce the same one. We can indeed determine whether the floating representations are equal, but this tells us little about equality of the true mathematical answers.
The undecidability of equality creates some interesting issues. If we divide a number by x, the calculator will compute more and more digits of x until it finds some nonzero ones. If x was in fact exactly zero, this process will continue forever.
We deal with this problem using two complementary techniques:
Prototypes of the M calculator, like mathematicians, treated all real numbers as infinite objects, with infinitely many digits to scroll through. If the actual computation happened to be 2−1, the result was initially displayed as 1.00000000, and the user could keep scrolling through as many thousands of zeroes to the right of that as he desired. Although mathematically sound, this proved unpopular for several good reasons, the first one probably more serious than the others:
As a result, the calculator now also tries to compute the result as an exact fraction whenever that is easily possible. It is then easy to tell from the fraction whether a number has a finite decimal expansion. If it does, we prevent scrolling past that point, and may use the fact that the result has a short representation to increase the font size. Results displayed in a larger font are not scrollable. We no longer display any zeros for non-zero results unless there is either a nonzero or a displayed decimal point to the right. The fact that a result is not scrollable tells the user that the result, as displayed, is exact. This is fallible in the other direction. For example, we do not compute a rational representation for π−π, and hence it is still possible to scroll through as many zeros of that result as you like.
This underlying fractional representation of the result is also used to detect, for example, division by zero without a timeout.
Since we calculate the fractional result when we can in any case, it is also now available to the user through the overflow menu.
The underlying evaluate-on-demand arithmetic package is described in H.

(Also at http://www.hpl.hp.com/techreports/2004/HPL-2004-70.html)
Our version has been slightly refined. Notably it calculates inverse trigonometric functions directly instead of using a generic "inverse" function. This is less elegant, but significantly improves performance.


Place: Karachi, Pakistan
Teams: Navy SEALs vs. OpFor
Type of Combat: Medium to short range combat
Terrain: Flat, desert town, multi-level structures
This map is a medium sized urban map. The map offers an excellent balance of open area combat, combined with building and rooftop battling.
One of the map's main advantages for players is the variation of levels, these different heights offer players the ability to use most of the guns. The small corridors of the buildings benefit shotgun and SMG users where a quick fire rate would be ideal. The rooftop locations and upper floor windows benefits players who use sniper rifles, assault rifles and LMGs as their extended range and damage can be utilized.
The nature of this map isn't friendly to players who use the higher Kill streaks. The ability to go into buildings can render the Predator Missile, Precision Airstrike, Harrier Airstrike, Attack Helicopter, Pave Low, Stealth Bomber, Chopper Gunner and AC130 Kill Streak rewards useless. Although they can still get kills as there are large open areas, rooftops and outdoor spawns, players should not expect to get 10 kills per streak every time.
The best places to call in a Care Package is the far back of the SEAL spawn, as there is only one way into that area, and the far back of the OpFor spawn near the school, as it is rare for players to enter these areas. The same goes for Emergency Airdrops, but it is ill-advised since there are many buildings with non-accessible rooftops as well as the edges of the level surrounding these areas.
Chopper Gunner does not work very well on this map, only if you are catching the enemy spawn will it work good as approx. 70% of this map is indoors. An AC-130 will be more effective but can still have difficulty if all enemies are hiding inside buildings. If they are, the player's teammates can throw a grenade to wipe them out and the AC-130 operator can begin decimating.
Rooftop camping is an easy way to complete the Prone Shot challenges.
Near the SEALS spawn, there is a ladder the player can climb up to a roof. To the right, it gives the player a large portion of open space to snipe.
In Domination, the player can set up a Sentry Gun to watch site B. At a high vantage point, it is relatively unnoticed and can get quite a few kills.
The player can view enemy names through the bus when prone, this is especially useful in Search and Destroy.
A smoke grenade can virtually conceal a bomb planter from enemy eyes without thermal scopes for at least 30 seconds. Grenades will still remain a problem unless thrown on the other side of the bomb planter.
When playing Domination, if the player is on the SEAL's team, the player could rush the OpFor team with a rushing class with Marathon and Lightweight at flag A. Most of the time the player could throw in a grenade/semtex, or fire a rocket at A - this can get the player any number of kills. Making multi-kills at the start is very possible and very likely. Alternatively, Danger Close could be used to boost the explosive damage of the player's explosive armanents.
Although it seems an obvious spot, the blown-out building near the B flag in Domination can be a highly effective method of suppressing an entire enemy team in Hardcore Ricochet:HQ Pro, especially if their spawn point is in the eastern side of the map.  The room is surprisingly easy to defend.
Maintaining the higher ground will give the player an upper hand, but there are many ways up, jeopardizing the player's control.


US judge sides with New York AG in Trump tax return lawsuit
Judge says Trump can't sue New York officials in a federal court in Washington, DC, to stop tax return release.
A United States federal judge on Monday dismissed New York's attorney general and state tax commissioner as defendants in President Donald Trump's lawsuit seeking to block a House of Representatives committee from obtaining his New York state tax returns.
US District Judge Carl Nichols in Washington, DC said he lacked jurisdiction over Letitia James, the attorney general, and Michael Schmidt, commissioner of the state's Department of Taxation and Finance. The dismissal was without prejudice.
Nichols said Trump could sue the New York officials in that state.

US judge rejects Trump challenge to release of his tax returns
The ruling may not end the lawsuit before Nichols. Trump also sued the US House Ways and Means Committee, and the judge ordered congressional lawyers and the president's attorneys to confer and file a joint status report outlining how they would propose to proceed.
New York passed a law earlier this year that would allow the congressional committee to access Trump's state tax returns.
Trump's lawyers filed a lawsuit in July, arguing that the New York law violates his free speech rights.
New York's law "was enacted to retaliate against the President because of his policy positions, his political beliefs, and his protected speech, including the positions he took during the 2016 campaign," Trump's lawyers said in a court filing.
The lawsuit is just one of several court fights over access to Trump's tax returns.
Last week, an appeals court in New York ruled that Trump's longtime accounting firm must hand over eight years of his tax returns to New York prosecutors. Trump's lawyers have said they will take that case to the US Supreme Court.

: productivity & analysis tools to scale your online marketing
You might be doing basic stuff, like copying and pasting text on spread sheets, you might be running large scale automated platforms with sophisticated algorithms, or somewhere in between. In any case your job is all about working with data.
As a data scientist you don't spend most of your time producing cool visualizations or finding great insights. The majority of your time is spent wrangling with URLs, figuring out how to stitch together two tables, hoping that the dates, won't break, without you knowing, or trying to generate the next 124,538 keywords for an upcoming campaign, by the end of the week!
advertools
is a Python package that can hopefully make that part of your job a little easier.
Installation
pip install advertools
# OR:
pip3 install advertools
SEM Campaigns
The most important thing to achieve in SEM is a proper mapping between the three main elements of a search campaign
Keywords (the intention) -> Ads (your promise) -> Landing Pages (your delivery of the promise) Once you have this done, you can focus on management and analysis. More importantly, once you know that you can set this up in an easy way, you know you can focus on more strategic issues. In practical terms you need two main tables to get started:
Keywords: You can generate keywords (note I didn't say research) with the kw_generate function.
Ads: There are two approaches that you can use:
Bottom-up: You can create text ads for a large number of products by simple replacement of product names, and providing a placeholder in case your text is too long. Check out the ad_create function for more details.
Top-down: Sometimes you have a long description text that you want to split into headlines, descriptions and whatever slots you want to split them into. ad_from_string helps you accomplish that.

SEO
Probably the most comprehensive online marketing area that is both technical (crawling, indexing, rendering, redirects, etc.) and non-technical (content creation, link building, outreach, etc.). Here are some tools that can help with your SEO
SEO crawler: A generic SEO crawler that can be customized, built with Scrapy, & with several features:
Standard SEO elements extracted by default (title, header tags, body text, status code, reponse and request headers, etc.)
CSS and XPath selectors: You probably have more specific needs in mind, so you can easily pass any selectors to be extracted in addition to the standard elements being extracted
Custom settings: full access to Scrapy's settings, allowing you to better control the crawling behavior (set custom headers, user agent, stop spider after x pages, seconds, megabytes, save crawl logs, run jobs at intervals where you can stop and resume your crawls, which is ideal for large crawls or for continuous monitoring, and many more options)
Following links: option to only crawl a set of specified pages or to follow and discover all pages through links
robots.txt downloader A simple downloader of robots.txt files in a DataFrame format, so you can keep track of changes across crawls if any, and check the rules, sitemaps, etc.
XML Sitemaps downloader / parser An essential part of any SEO analysis is to check XML sitemaps. This is a simple function with which you can download one or more sitemaps (by providing the URL for a robots.txt file, a sitemap file, or a sitemap index
SERP importer and parser for Google & YouTube Connect to Google's API and get the search data you want. Multiple search parameters supported, all in one function call, and all results returned in a DataFrame

(log files, XML sitemaps, robots.txt files, and lists of URLs)
Social Media
In addition to the text analysis techniques provided, you can also connect to the Twitter and YouTube data APIs. The main benefits of using
advertools
for this:Handles pagination and request limits: typically every API has a limited number of results that it returns. You have to handle pagination when you need more than the limit per request, which you typically do. This is handled by default
DataFrame results: APIs send you back data in a formats that need to be parsed and cleaned so you can more easily start your analysis. This is also handled automatically
Multiple requests: in YouTube's case you might want to request data for the same query across several countries, languages, channels, etc. You can specify them all in one request and get the product of all the requests in one response

IRFU confirm new Bundee Aki deal to keep him with Connacht until 2023
The 29-year-old has penned a new deal with the union.
by Murray KinsellaTHE IRFU HAS confirmed that Bundee Aki has signed a new central contract to keep him with Connacht until the summer of 2023 at least.
The Ireland international is the first Connacht player to sign a central deal with the union, and this new three-year extension comes as a huge boost for the western province.
Aki first joined Connacht in 2014 and has gone on to become a much-loved figure within the province. He made his Ireland debut in 2017 after qualifying on residency grounds and has established himself as a key cog in the national team since.
The New Zealand native has now moved onto a central contract that will keep him with Connacht until the end of the 2022/23 season.
“I am grateful for the opportunity I have been given to represent both Connacht and Ireland and am delighted to extend my IRFU contract,” said Aki of his new deal.
“The whole of Connacht have been incredibly supportive of both me and my family and the Ireland supporters have been fantastic from the very first day I was selected for the national squad.
“Connacht has become home to me and my family and I want to play my part in helping Connacht achieve their ambitious plans in the years to come.”
Aki understandably attracted interest from abroad, but the IRFU is delighted to keep him on Irish soil.
“Bundee has added significant value to both the Ireland and Connacht environments,” said IRFU performance director David Nucifora.
“He has performed at a consistently high level, is a leader and has a positive impact on younger players around him with his insight and the professionalism and diligence of his preparation.
“We are delighted that he will continue to play a positive role in Irish rugby for years to come.”
Connacht CEO Willie Ruane also welcomed confirmation of the new deal for Aki, which comes hot on the heels of scrum-half Kieran Marmion committing to the province for another three years.
“Connacht Rugby is delighted that Bundee has extended his contract to 2023,” said Ruane.
“This is the third time that Bundee has committed to Connacht Rugby which reflects not only his belief in what we are doing but also our commitment in supporting him to achieve for both Connacht and Ireland.”
Bernard Jackman and Murray Kinsella join Gavan Casey to discuss eye-gouging, Munster’s scrum-half situation, and the rest of the provincial news.


Preference Editing Tools
The Floe Project is collaborating with the Global Public Inclusive Infrastructure to build tools to allow users to create personalized digital interfaces. These preference management tools enable and promote the discovery, adjustment and application of user preferences across multiple devices. A user will be able to customize any interface they might encounter by exploring and then declaring preferences, saving them to the cloud, and applying them to devices (both private and public). For example, a user may use these tools to discover and adjust their preferences on a personal laptop, and later apply these preferences to a public ticketing kiosk.
Personalized interfaces have the potential to help digital users overcome barriers to access and participation in an increasingly digital world. Interfaces that meet users where they are, adapt to their unique needs, and empower them to participate by putting the personalization decisions in their hands are not only possible, but are a necessity for many to “get in the digital door.” The goal of this personalization is to make interaction with technology as painless and as enjoyable as possible for all.
For more information and to see an example of preference management tools in action, please see the video below.
