Poisson’s equation is written as
|
| (179) |
where −𝜀0∇2δΦ is called the space-charge term. Since we consider modes with k∥≪ k⊥, the space-charge term is approximated as ∇2δΦ ≡∇⊥2δΦ + ∇∥2δΦ ≈∇⊥2δΦ. Then Eq. (179) is written as
|
| (180) |
This approximation eliminates the parallel plasma oscillation from the system. The perpendicular plasma oscillations seem to be partially eliminated in system with gyrokinetic ions and drift-kinetic electrons. There are the so-called ΩH modes (also called electrostatic shear Alfven wave) that appear in the gyrokinetic system which have some similarity with the plasma oscillations but with a much smaller frequency, ΩH ∼ (k∥∕k⊥)(λD∕ρs)ωpe.
Using expression (151), the perturbed number density δn is written as
where the blue term is approximately zero for isotropic F0 and this term is usually dropped in simulations that assume isotropic F0 and approximate δA as δA∥e∥. The red term in expression (181) is the so-called the polarization density np, i.e.,|
| (182) |
which has an explicit dependence on δΦ and is usually moved to the left hand of Poisson’s equation when constructing the numerical solver of the Poisson equation, i.e., equation (180) is written as
|
| (183) |
where δni′ = δni −δnpi = ∫ δhidv, which is evaluated by using Monte-Carlo markers. Since some parts depending on δΦ are moved from the right-hand side to the left-hand side of the ﬁeld equation, numerical solvers (for δΦ) based on the left-hand side of Eq. (183) probably behaves better than the one that is based on the left-hand side of Eq. (180), i.e., −𝜀0∇⊥2δΦ.
The polarization density is part of the perturbed density that is extracted from the source term and moved to the left-hand side of the Poisson equation. The polarization density will be evaluated without using Monte-Carlo markers, whereas the remained density on the right-hand side will be evaluated using Mote-Carlo markers. The two diﬀerent methods of evaluating two parts of the total perturbed density can possibly introduce signiﬁcant errors if the two terms are expected to cancel each other and give a small quantity that is much smaller than either of the two terms. This is one pitfall for PIC simulations that extract some parts from the source term and move them to the left-hand side. To remedy this, rather than directly moving a part of the distribution function to the left-hand side, we subtract an analytic expression from both sides of Eq. (180). The analytical expression is evaluated based on grid values of perturbed electromagnetic ﬁelds and are independent of makers. All the original parts of the distribution functions are kept on the right-hand side and are still evaluated by using markers, which hopefully avoids the possible cancellation problem. This strategy is often called a cancellation scheme.
It turns out the cancellation scheme is not necessary for Eq. (183), but for the ﬁeld solver for Ampere’s equation (discussed later), this cancellation scheme is necessary in order to obtain stable results.
Note that two things appear here: What motivates us to move parts of the distribution function to the left== >hopefully to make the left-hand side matrix more well-behaved (such as good condition number, etc.) Why do we need the cancellation scheme== >to avoid numerical accuracy problem appearing when large terms cancels each other== >iteration is needed when the cancellation scheme is used because the right-hand side explicitly contains unknown electromagnetic ﬁelds.

NVAPI Reference Documentation
|
|
Release 343: September 30
|
Functions | |
| NVAPI_INTERFACE | NvAPI_Initialize () |
| NVAPI_INTERFACE | NvAPI_Unload () |
| NVAPI_INTERFACE | NvAPI_GetErrorMessage (NvAPI_Status nr, NvAPI_ShortString szDesc) |
| NVAPI_INTERFACE | NvAPI_GetInterfaceVersionString (NvAPI_ShortString szDesc) |
| NVAPI_INTERFACE NvAPI_GetErrorMessage | ( | NvAPI_Status | nr, |
| NvAPI_ShortString | szDesc | ||
| ) |
This function converts an NvAPI error code into a null terminated string.
SUPPORTED OS: Windows XP and higher
| nr | The error code to convert |
| szDesc | The string corresponding to the error code |
This function returns a string describing the version of the NvAPI library. The contents of the string are human readable. Do not assume a fixed format.
SUPPORTED OS: Windows XP and higher
| szDesc | User readable string giving NvAPI version information |
This function initializes the NvAPI library. This must be called before calling other NvAPI_ functions.
SUPPORTED OS: Windows XP and higher
| NVAPI_ERROR | An error occurred during the initialization process (generic error) |
| NVAPI_LIBRARYNOTFOUND | Failed to load the NVAPI support library |
| NVAPI_OK | Initialized |
DESCRIPTION: Unloads NVAPI library. This must be the last function called.
SUPPORTED OS: Windows XP and higher
!! This is not thread safe. In a multithreaded environment, calling NvAPI_Unload !!
!! while another thread is executing another NvAPI_XXX function, results in !!
!! undefined behaviour and might even cause the application to crash. Developers !!
!! must make sure that they are not in any other function before calling NvAPI_Unload. !!
Unloading NvAPI library is not supported when the library is in a resource locked state. Some functions in the NvAPI library initiates an operation or allocates certain resources and there are corresponding functions available, to complete the operation or free the allocated resources. All such function pairs are designed to prevent unloading NvAPI library.
For example, if NvAPI_Unload is called after NvAPI_XXX which locks a resource, it fails with NVAPI_ERROR. Developers need to call the corresponding NvAPI_YYY to unlock the resources, before calling NvAPI_Unload again.
| NVAPI_ERROR | One or more resources are locked and hence cannot unload NVAPI library |
| NVAPI_OK | NVAPI library unloaded |

The home page has 3 responsive sizes and at each size consideration must be made as to what will be visible as the image grows and more get cropped as the browser window gets larger
At the mobile size the image is entirely visible and has a width to match the next break point. ie tablet at 760px. It will resize to fit the users browser width.
Dimensions
Width: 760px
Height: match aspect ratio
Visible
Width: 100%
Height: 100%
The tablet version has a width of the desktop breakpoint ie. 1030px. It will resize to match the users browser size. However not all the image is visible. the viewable area is in the center of the photo with a height of 400 pixels from the center no mater the size of the browser. The width of the viewable area is 100%, however it will be partially obscured by Hero text area that was a width of 300px and has a transparency of 90%.
Dimensions

Height: match aspect ratio
Visible
Width: 100% - 300px
Height: 400px
Text area
Opacity: 90%
Width: 300px
Height: 400px
The desktop version has a width of 1920 pixels and it will resize so that 100% of the width is visible. However only 400 pixel of the height is ever visible no mater the size of the browser. This means that the wider the users browser is the more narrow the visible photo is. Alos there is hero text in a box that sits the right hand side of the layout with a width of 400 pixles and a height to match the content that completely blocks the image.
Dimensions
Width: 1920px
Height: match aspect ratio
Visible
Width: 100%
Height: 400px
Text area
Width: 400px
Height: match text
The most used image type is this one. there are 3 uses and 2 versions for the image. All versions maintain the aspect ratio of the desktop version.
This type of image is used on the following pages
The mobile version of the hero image is used as the heading for the tiles that appear on themepages. This is regardless of the device or browser width as theme tiles will never be wider than 760px.
This version is also used as the hero image for the above mentioned pages and is only visible within the mobile breakpoint
Dimensions
Width: 760px
Height: 217px
Used as the hero image for the above mentioned pages, this version is visible on the tablet and desktop breakpoints
Dimensions
Width: 1050px
Height: 300px
This image is added by the content team and is by default responsive up to a width of 500px and centered. There are classes avaiable to the content team to deviate from this. Documented here
This image is located in the tiles that are the result of a search on partner content at the bottom of an article.
It will keep the originals aspect ratio but will have a height of 40px with no white trim
Dimensions
Width: match aspect ratio
Height: 40px
This image is the same as the partner logo that appears on a content page. It is located in the tiles that are the result of a search on partner content at the bottom of an article.
It will keep the originals aspect ratio but will have a height of 40px with no white trim
Dimensions
Width: match aspect ratio

The quick brown fox jumps over the lazy dog.
This page serves to demonstrate a responsive grid system in 12- and 16-column flavors. Using CSS grid and media queries, the page reflows and serves screens from 240px wide to full-size desktop resolutions.
Unlike my earlier fluid grid, IE 7 and 8 will not be served a separate stylesheet; their current browser share is too small to be catered to. This has been tested and works as expected in all major browsers with 2% or greater market share as of February 2018.

Dengue virus, which is in the flavivirus family, is a worldwide spread virus and has huge impact on society, however, not many developing countries are recognizing its danger.
Dengue virus is unique in terms of its four different serotypes. Multiple infection can easily cause severe dengue, appearing hemorrhage and organ damage. It is important to grasp which serotype the patient is infected, however, there is not enough data about each serotype in a year.
To tackle the situation, we took the following two approaches.
In the future, this system can contribute to other flavivirus detection system.

AFormatter
Direct Subclass:
This is the core formatter. It contains most of the logic behind the formatting, and it is written in such a way that it is easily extendable to other programming languages. To create a formatter for a new programming language, extend this class and follow the JavaFormatter as an example.

Public Methods
public format(code: *, expressionIdentifier: *, scopeEnterFunc: *, scopeExitFunc: *, formatCommentsFunc: *): Array source
Format a string of code. The string will be cut into lines and lines will be indented accordingly to their scope.
As a reference, look at the format function in the JavaFormatter.
Params:
| Name | Type | Attribute | Description |
| code | * | String of code to format. |
|
| expressionIdentifier | * | Function that identifies if a line qualifies as an expression:
|
|
| scopeEnterFunc | * | Function that identifies if a new scope is entered in a line. |
|
| scopeExitFunc | * | Function that identifies if a scope is exited in a line. |
|
| formatCommentsFunc | * | Function that formats comments (e.g. add space before body and end comment in Javadoc) |
public formatSnippet(code: *, startRow: *, endRow: *, offset: *, expressionIdentifier: *, scopeEnterFunc: *, scopeExitFunc: *, formatCommentsFunc: *, identifyMethodSigFunc: *, identifySpecialStatement: *, bodyCommentToken: *, simpleCommentToken: *): Array source
A slight variation of format(codeString). Useful if you want to display a code snippet around a selection of lines.
As a reference, look at the formatSnippet function in the JavaFormatter.
In addition to indenting lines, formatSnippet takes a selection as a start and end row in a large slab of code and cuts out a snippet of code around this selection. The start and end of the snippet is based on an offset that is provided as a parameter. The offset with the start and end of the selection create a sort of range from which the snippet is taken.
In the example below, the selection is identified to belong to test2() and thus only test2() is returned. If the method is longer than the offset, than only the part within the offset will be returned. No code is added to the range with the exception of comment lines above the selection, to close unfinished comments.
Params:
| Name | Type | Attribute | Description |
| code | * | The original code base in which the selection is. |
|
| startRow | * | The start row of the selection in the code base. |
|
| endRow | * | The end row of the selection in the code base. |
|
| offset | * | The offset the defines the range on which to base the snippet. |
|
| expressionIdentifier | * | Function that identifies if a line qualifies as an expression: An expression is defined as:
|
|
| scopeEnterFunc | * | Function that identifies if a new scope is entered in a line. |
|
| scopeExitFunc | * | Function that identifies if a scope is exited in a line. |
|
| formatCommentsFunc | * | Function that formats comments (e.g. add space before body and end comment in Javadoc) |
|
| identifyMethodSigFunc | * | Function that identifies if a line is a method signature. |
|
| identifySpecialStatement | * | Function that identifies if a line contains a special statement (e.g. comment or '@' in Java) |
|
| bodyCommentToken | * | The token for 'body comments' (e.g. '*' in Java) |
|
| simpleCommentToken | * | Simple comment token (e.g. '//') |
Return:
| Array | An array of formatted lines that form the snippet, separated into prefix selection and suffix, as well as the start and end lines of the snippet in the original code base. |
Example:
START:
1. @Test
2. public void test1() {
3. System.out.println("Test 1");
4. }
5.
6. // ------------------
7. // Perform test 2.

Defining Facebook's Problem 2. Contributions of Paper 3. HiveQL 4. HDFS 5. System Architecture 6. Demo 7. Conclusions --- # Defining Facebook's Problem - Facebook's data storage prior to 2008 was done on a trditional RDBMS - Their data was rapidly expanding and was already taking too long to perform menial queries. - Simple queries would take days to complete. ??? --- # Defining Facebook's Problem - Facebook started to investigate Hadoop MapReduce as a solution. - Allthough beneficial, the query time saved was lost in constructing queries in a MapReduce manor. - Many developers at Facebook took days to construct these simple queries. ??? --- # Defining Facebook's Problem - As a result, Facebook developed Hive. - Their objective was to create a scalable infrastructure that operated like a traditional RDBMS would. - Hive was to have columns, tables, and traditional SQL operation commands. ??? --- # Contributions - Hive offers traditional SQL queries and data management on a distributed MapReduce storage system. - Hive's custom serialization offers users the ability to store custom data types. - Hive's HDFS and the underlying architecture provide's a 20% decrease in runtime compared to traditional MapReduce architectures at the time. ??? --- # The Hive Model - Hive structures data into tables, columns, rows, and partitions. - The system supports many common datatypes: int, float, string, etc. - The system can also support complex and custom datatypes defined through serialization. ??? --- # HiveQL - HiveQL is a subset of SQl. - It contains extended operations that are useul in a distributed architecture. - Although it is a subset of SQL, there are some limitations. ??? --- # HiveQL - HiveQL can only support ANSI JOIN statements.
??? --- # HiveQL ### Custom MapReduce - HiveQL has support for using custom map and reduce scripts in queries. - This allows for more customization queries and additional operations like classification, clustering, etc.
??? Note that Hive also supports clustering operations to reduce the load put on the reduce operations. Note that Hive supports the interchanging of FROM, SELECT, MAP, and REDUCE within a sub query. --- # HiveQL ### Custom MapReduce Data
--- # HiveQL ### Custom Map
--- # HiveQL ### Custom Reduce
??? --- # HiveQL ### Serialization - HiveQL supports custom data types with serialization. - The default serialization is done through LazySerDe. --- # HiveQL ### Serialization - SerDe serializes rows into objects. - In the table definition, HiveQL can specify row, column, list, and map value delimiters for serialization.
??? Note that collection items are delimiters for the elements in a list. List items are rows in this case. Map keys are delimiters for items in a map. --- # HDFS -
Tables
: stored in directory. -
Partitions
: stored in subdirectory within table directory. -
Buckets
: stored as a file within a table or partition directory. --- # HDFS ### Tables - Tables can have many partitions, or operate without partitions. - Tables are partitioned with custom PARTITIONED BY functions.
??? Note that the table will be create with partitions existing for every 'date' and 'hour' --- # HDFS ### Partitions - Partitions allow Hive to perform queries much faster. - They enable partition pruning, which will allow Hive to only query sub directories of tables.
??? The first creates a partition with data from table t and the second creates and empty partition. --- # HDFS ### Buckets - Buckets can be used to scan files within partitions or tables.
??? Note that this queries the 2nd bucket file out of the 32 buckets in the table. Note that these buckets can be used for clustering tables. --- # System Architecture ### Summary The main building blocks of Hive are:
- Metastore - Compiler - Optimizer - MapReduce Execution --- # System Architecture ### Metastore - Metastore stores location data and metadata on all tables, partitions, columns, etc. - This information is stored in a traditional RDBMS (MySQL) - There are often duplicate metastore servers in case one is terminated or is hung. ??? The info is stored in a RDBMS because the compiler needs this info quick. Without metastore, there is no structure for the data stored in HDFS. --- # System Architecture ### Query Compilation and Optimization - The compiler and optimizer takes in the HiveSQL queries and translates them into map and reduce tasks.
[1] ??? - The analyser transforms the syntax trees into an internal query representation with query blocks. - The analyser queries the metastore for information on tables to insert into internal queries. - The logical plan generator will take the internal queries and order them in a logical plan in an operation tree. - The query plan generator converts the ordered logical plan into a series of map-reduce jobs. --- # System Architecture - Parser
[1] --- # System Architecture - Parser
[1] ??? - The parser converts queries intox syntax trees. - The first block is the column selection from the underlying tables - The second block contains the destination information for the overwrite operation - The third block contains the join information and ON clause information for the two tables. --- # System Architecture - Semantic Analyzer
[1] ??? - The analyser transforms the syntax trees into an internal query representation with query blocks. --- # System Architecture - Semantic Analyzer
[1] ??? - The analyser transforms the syntax trees into an internal query representation with query blocks. --- # System Architecture - Semantic Analyzer
[1] ??? - The analyser transforms the syntax trees into an internal query representation with query blocks. --- # System Architecture - Logical Plan
[1] ??? - The logical plan generator will take the internal queries and order them in a logical plan in an operation tree. --- # System Architecture ### Optimization There are several optimization steps that occur to prune the logical plan created by the semantic analyser. - Column pruning - Predicate pushdown - Partition pruning - Map side joins ??? -Note predicate pushdown has to deal with the immediate execution of queries as they come in. --- # System Architecture ### Optimization - Pruning - Column pruning ensures that only the specified columns are selected when processing rows. - Partition pruning ensures that only sub directories of tables are traversed when querying tables. --- # System Architecture ### Optimization - Joins - Map side joins allows the replication of small tables inside of map workers so that the join can be part of mapping. - Map side joins reduce the load sent to reduce tasks. --- # System Architecture ### Optimization - Predicate Pushdown - Predicate pushdown prioritizes certain operations in a query in order to lessen load.
??? - The WHERE clause is evaluated first on the two tables before the join with predicate pushdown. --- # System Architecture - Query Plan
[1] ??? - The query plan generator converts the optimized logical plan into a series of map-reduce jobs. - The execution engine then takes this plan and executes based on dependencies. --- # Demo --- # Conclusions - Hive provides an easy to use query language to extract data from Hadoop MapReduce backends. - The HDFS with partitions and buckets contribute to faster queries through pruning. - Outside of pruning, Hive's data structuring and optimization provides a system that performs ~20% faster than traditional Hadoop systems during that time. --- # References [1] http://www.slideshare.net/recruitcojp/internal-hive

What are these controllers
? It is a good question for a newb. In the MVC
paradigm
a Models could be described as a very weird and hard to understand thing.
When you look in the browsers navigation’s bar, you will see something like:
http://localhost:3301/welcome/to/my/site
The Universal Resource Locator (URL) is showing you a “structured” web site running inside a server that listening in the 3301’s port. The site’s internals routes is “drawing” the path: Inside the root_dir/ are the directory /welcome/ an it content recursive the some others dirs: “to”, “my” and “site”(./to/my/site)
But that is virtual, the site have not really a directory structure like that… That would be useless. The site use a “routes drawing system” for get a control of that routes and that is what the controller does.
In camping, each "capitalized"
word is like the slash. For example:
WelcomeToMySite
Shall draw a route like:
/welcome/to/my/site
Or you could use instead the weird R for get more control in your routes
Welcome < R '/welcome/to/my/site'
All of this will be declared inside the Nuts::Controllers module
Controllers can also handle your application’s parameters. For example when the client ask four a route like /post/1 the static web server shall look out for the dir number 1 and serve the content. It should have a lot of “number-named” directories for do that simple job.
But the controller, draw a dynamic path for every asked post. Wee just need to tell him about the size of the flock.
In camping, the N and the X in a controller’s declaration, mean a parameter:
class PostN
Will trigger the /post route and any number after it. For exmaple,
/post/1
/post/99
But it will not, math against a word. For example, if asking /pots/mypost it will return 404. Because the PostN only math Numeric parameters.
If you like to math anything else, you should write a controller like:
class PostX
The X mean: -math anything, including number and words. It will math:
/post/1
/post/99
/post/mypost
But it will NOT math: /post/mypost/1 or anything that could have a slash. Because a “/” mean: “the next directory”, and that is another Capitalized word.
Ok, we have the controller that match parameters; and now what?
You will like to show the post number N asked in the controller. You need the number.
class PostN
def get number
p "the parameter was: #{number}"
end
end
Please, do not try that at home, is very dirty using a view inside the controller.
The method get, for the /post/N route, will take a parameter. That number will by inside the “number parameter”. From now, if you like to route something to you post route, you will write a link 100% pragmatically like this:
@post=rand 1..9
a "See the post number: #{@post}",:href=>R(PostN,@post)
For that example, we just, choose a random post and then show a link for follow the path.
-but you told me that should now write that thing in the controller
Yep… I told. The things like that, are views, because that thats part, will be in the user’s face. Our client will not see the controllers, their view, the views.

This is just a small demonstration. It really gets interesting when you start to play with the schema on the server side. Fortunately it's
pretty easy to do. sangria-playground is available on the
GitHub, and since it's a simple Play application,
all it takes to start playground locally and start playing with the schema is this:
$ git clone https://github.com/sangria-graphql/sangria-playground.git
$ cd sangria-playground
$ sbt run
Now you are ready to point your browser to http://localhost:9000 to see the same page you are seeing here.
The only prerequisites are SBT and Java 8.


Krita has a new Forum - krita-artists.org
by Raghavendra Kamathraghukamath writes:
Introducing Krita-Artists.org - A community for Krita artists, developers and enthusiasts.
After coming back from the Blender conference the maintainer of the Krita project Boudewijn Rempt wished for a website for Krita community similar to Blenderartists.org, which will be maintained by the community and not by the developers or core team.
Some of the community members liked this idea and took to the task of creating the website and the result is krita-artists.org.
We would like to invite all Krita artists and enthusiasts to come and join us on the new forum, share artworks made with Krita, share experiences working with Krita, collaborate with others, provide feedback to the Krita developers and have fun together.
A lot of thanks to Discourse and blenderartists.org for leading the way and being inspiration to this website.

Why Yahoo Boys Make More Money Than Politicians – Bago
by Faderera FaladeHon. Dachung Bago, a house of Representative member representing Jos South/Jos East Federal Constituency, has said that ‘Yahoo yahoo’ boys in Nigeria make more money through cybercrime activities.
The lawmaker who doubles as a member of the House of Representatives Ad-hoc Committee on the rising cases of SIM swap fraud spoke while reacting to EFCC’s revelation of how bank officials partner with cybercriminals wondered at the sophistication with which cybercriminals operates.
Bago urged the anti-graft agency to double effort in fighting fraud while adding that yahoo boys are way ahead in cybercrime and transferring huge sums of money from Bank account illegally.
He shared his disappointment in Nigerians who believe politicians are making a lot, insisting that Yahoo boys make more money cheaply and illegally than politicians.
“A single yahoo boy can transfer huge sums of money equal to the budget of a state at a go.
“They sit down with their laptop transferring money illegally from a bank customer to their own, while politicians cannot have money up to a monthly allocation of a local government in four years. ”
The lawmaker urged the EFCC not to spare anyone caught in cybercrime activities, noting that cybercrime laws were sufficient to deal with culprits.


The app pulls cloudaudit and access Bitglass log data filtered down to the specified DLP patterns. It also provides actions for access to Bitglass REST APIs for group and user manipulation. A sample playbook is included.
Troubleshooting tips, known issues, and miscellaneous notes
- After installing the app, please perform the following configuration steps:
- Create a new asset and save the required settings 'OAuth 2 Authentication Token' and 'Bitglass API URL' in the 'Asset Settings' tab
- In the 'Ingest Settings' tab, select the source (i.e 'events') and enable polling interval or another scheduling option, press SAVE
- Do 'Asset Settings / TEST CONNECTIVITY' and make sure it passes
- The Phantom logs are available in /var/log/phantom or ${phantom_home}/var/log/phantom (for a non-root installation)
- The last ingested data with the time and error code (if failed) is available in the app state directory /opt/phantom/local_data/app_states/8119e222-818e-42f5-a210-1c7c9d337e81 in lastlog-*.json files
- Optionally, install the bitglass_dlp_response.tgz playbook sample before creating your playbook from scratch
The actions available with the app roughly fall into 3 groups
Phantom standard and Bitglass log event retrieval
- 'test connectivity': Phantom requirement to test the asset settings (API url, authentication token, etc.)
- 'on poll': Phantom requirement for automatic data ingestion. Only the 'DLP Pattern for Access' and 'DLP Pattern for CloudAudit' matches from the log types 'Access' and 'CloudAudit' correspondingly get ingested into Phantom
- 'filter by dlp pattern': Additionally to filtering done according to the asset params 'DLP Pattern for Access' and 'DLP Pattern for CloudAudit' (as part of the ingestion), filter the ingested Bitglass log events further down as defined by the 'bg_match_expression' action param
User manipulation in response to log events from either Bitglass or other vendors
- 'add user to group': Add the user from the offending log event to a Bitglass group. For Bitglass log event source, the user is determined according to the asset params 'DLP Pattern for Access', 'DLP Pattern for CloudAudit' and the 'bg_match_expression' param of the 'filter by dlp pattern' action by chaining this action after 'filter by dlp pattern'
- 'remove user from group': Same but in reverse
- 'deactivate user': A more drastic action in comparison to 'add user to group' above
- 'reactivate user': Same but in reverse
Other available actions covering the rest of the methods in Bitglass REST API, please refer to the online documentation for reference
- 'create update user'
- 'create update group'
- 'delete group'
The following describes creating a simple playbook from scratch for the 'User manipulation' use case described above. The resulting playbook should be similar to the sample bitglass_dlp_response.tgz playbook included with the app package
- Go to the 'Playbooks' page and click '+ PLAYBOOK'
- Drag the arrow on the 'START' block and click 'Action' in the menu on the left
- Choose 'Bitglass', the available actions will be listed
- Choose 'filter by dlp pattern'. This action will narrow down the available data (in the form of Phantom artifacts already available and the ones to be ingested into the future)
- Choose the asset configured earlier. Please note, that the artifacts available on the system have been already pre-filtered according to the 'DLP Pattern for Access' and 'DLP Pattern for CloudAudit' asset settings
- Override the 'bg_match_expression' and 'bg_log_event' params if necessary (keeping the defaults values of Malware.* and artifact:*.id correspondingly should be good for a start)
- Click 'SAVE'. That concludes defining the first action
- Pull at the output pin of the first action and click 'Action' to define the next action
- Choose 'Bitglass', the available actions will be listed
- Choose 'add user to risk group'. This action will extract the user name from the artifact data corresponding to the log event and call Bitglass REST API to add the offending user to the group of risky users
- Choose the same asset configured earlier
- Override the 'bg_group_name' param if necessary. This group must have been created previously so that it exists
- For the 'bg_user_name', this value has been extracted by the previous action and is available to pick as 'data.*.userName', use it
- Click 'SAVE'. That concludes defining the second action
- Connect the output pin of the second action to the 'END' block
- Click 'PLAYBOOK SETTINGS' and set 'Operates on' to 'events' and check 'Active'
- Enter the desired playbook name in the upper left corner
- Click the 'SAVE' button
- Enter the description if prompted and click the 'SAVE' button
- From now on, the playbook will be run automatically whenever new data conforming to the filter parameters defined above arrives
- IMPORTANT! If using the Playbook Debugger or invoking the playbook manually, be sure to change the default value of the 'Scope' setting from the default 'new' to 'all'. Skipping this step will result in a Phantom error as the input data set will be empty in such a case
The following table summarizes all the params available

THE SILENCE OF THE LAMBS A film review by Frank Maloney Copyright 1991 Frank Maloney
THE SILENCE OF THE LAMBS is Jonathan Demme's adaptation of a novel by Thomas Harris and it knocked my socks off.
It is a thriller about serial killers, one known and in high-security detention, one unknown and on a bloody rampage. The former is played by Anthony Hopkins, who has created the creepiest, most disturbing villain I have ever seen in a movie. He is totally convincing as "Hannibal the Cannibal," alarming, charming and vile, intelligent, perceptive, a human animal. If Hopkins doesn't get a best-actor nomination next year, it will be because the film was released too early in the year, although how anyone who sees his performance can ever forget it is beyond me.
He forms a bizarre alliance with an FBI agent-in-training played by Jodie Foster. Foster turns in an excellent performance that ought to establish her as a creditable adult actor. Her performance isn't as flashy as Hopkins, but it's thorough and convincing throughout.
I have only one cavil: the other, on-the-loose killer is a gay man. Okay, there are probably a proportionate number of gay people among killers and psychopaths as in the world at large. But I can see no particular reason why this one has to be gay. Because he thinks he's a transsexual the film seems to say. Hogwash! I think the real reason is that a stereotype and a prejudice is being exploited and I say shame on Demme and company.
One of the things I like about SILENCE is the way the film plays with who are good guys and who are bad guys. Hopkins, for instance, is presented as exactly what he is and yet at the end we like him, knowing full well the evil he does. Another character, who is on the right side of the bars, the director of the asylum where Hopkins is kept, is clearly marked from the beginning as a villain and we cheer his final fate. The other killer, "Buffalo Bill," is presented without any ambiguity--all bad, but interesting.
There are consistently good characterizations of the major players, all too rare a quality in contemporary scripts. In particular, we learn a lot about Foster's character--even though she is a woman, contrary to such movies as THE FABULOUS BAKER BOYS and RUSSIA HOUSE. Also, I was pleased that no one had to fall in love with anyone else, although two intriguing friendships develop for Foster.
The film is ably photographed without particularly drawing attention to itself or making any obvious contribution to the meaning of the film, unlike a film such as L.A. STORY where the camera's love affair with Los Angeles is a substantial part of the film.
One WARNING: this film is a very tense affair with blood, violence, and mutilation. Most of the worst happens out of the range of the camera, but enough is shown and the rest talked about so it may disturb some viewers excessively. Several people in my audience clearly couldn't take it any more and exited after one particularly grueling scene. There is also strong language and some nudity.

Noel Gallagher wants to play guitar for The Smiths if they ever reunite
But he's not holding out hope...
Noel Gallagher has revealed that he’d be up for becoming a guitarist in The Smiths if the Manchester icons were to ever reunite.
In a new interview with Zane Lowe on Beats 1, the High Flying Birds singer revealed that he’s keen on taking the background as a guitarist once more, and later said The Smiths would provide the perfect place to do so.
“I would love to be in a band and just be a guitarist for a while,” Noel said.
“Not that band [Oasis], but sometimes when I sit in with [Paul] Weller I just think ‘thank god for that’.”
When asked by Lowe which band he would “jump at” to join, Noel revealed that the ‘Panic’ band – comprised of Morrissey, Johnny Marr, Mike Joyce, Andy Rourke and later Craig Gannon – would be the ideal choice.
“I would love, and it’s never gonna happen, it’s a thing in a parallel universe, if The Smiths got back together.
This comes after Noel admitted earlier this year that The Smiths were the one band he would love to see reunite.
“I’m not into reunions and all that,” he told Radio X.
“But if there was one… If I was God for a day… If you could make it happen and they’d all be happy about it happening, I would love to see The Smiths again.”
But it seems as unlikely as ever, with Johnny Marr jokingly dismissing the suggestion earlier this month.
Meanwhile, Noel’s war of words with estranged brother Liam rages on, with Noel recently admitting that Liam’s Twitter account is the reason why Oasis will never reunite.
Last week, he also released his uplifting new single ‘Wandering Star’, taken from his upcoming third EP, ‘Blue Moon Rising.’

choice of espresso
If there were a situation in which I had to spend money on an espresso, and I had SGD$6 - which could only be spent on espresso - and a choice of espresso from any coffee-shop in Singapore, I would go to La Ristrettos and get theirs, which is sold at $3.
When I was there once, a member of the staff told me he had served me espresso that was single-origin (probably he was referring to the coffee beans - which, on that day, he might have said was from Ethiopia).
The other $3? If I could, I would go back there another day to spend it.

January 24 St. Francis de
Sales
FIRST READING Ephesians 3:8-12
Brethren: To me, though I am the very least of all the
saints, this grace was given, to preach to the Gentiles the unsearchable riches
of Christ, and to make all men see what is the plan of the mystery hidden for
ages in God who created all things; that through the church the manifold wisdom
of God might now be made known to the principalities and powers in the heavenly
places. This was according to the eternal purpose which he has realized in
Christ Jesus our Lord, in whom we have boldness and confidence of access
through our faith in him.
The word of the Lord
RESPONSORIAL PSALM Psalm 37

mouth of the just man utters wisdom.
Trust in the LORD and do good; then you will dwell in the land and safely
pasture. Find your delight in the LORD, who grants your heart's desire.
R. The
mouth of the just man utters wisdom.
Commit your way to the LORD; trust in him, and he will act, and make
your uprightness shine like the light, the justice of your cause like the
noon-day sun.
R. The
mouth of the just man utters wisdom.
The mouth of the just man utters wisdom, and his tongue tells forth what
is right. The law of his God is in his heart; his steps shall be saved from
stumbling.
R. The

ALLELUIA John 13:34
R. Alleluia. A new commandment I give to you, says the Lord, that you love one another, even as I have loved you. R. Alleluia.
GOSPEL John 15:9-17
At that time: Jesus said to his disciples, ďAs the Father has loved me,
so have I loved you; abide in my love. If you keep my commandments, you will
abide in my love, just as I have kept my Father's commandments and abide in his
love. These things I have spoken to you, that my joy may be in you, and that
your joy may be full. "This is my commandment, that you love one another
as I have loved you. Greater love has no man than this, that
a man lay down his life for his friends. You are my friends if you do what I
command you. No longer do I call you servants, for the servant does not know
what his master is doing; but I have called you friends, for all that I have
heard from my Father I have made known to you. You did not choose me, but I
chose you and appointed you that you should go and bear fruit and that your
fruit should abide; so that whatever you ask the Father in my name, he may give
it to you. This I command you, to love one another.

Crypto Analyst: Ethereum, XRP and Altcoins Poised for Major Rally As Bitcoin (BTC) Dominance Drops
by Daily Hodl StaffA crypto analyst and self-proclaimed “whale whisperer” says Ethereum, XRP and the altcoin market at large may be poised for a major rally.
The analyst, who goes by the name Beastlyorion, tells his 57,000 followers on Twitter that Bitcoin’s dominance of the overall crypto market is testing support at around 66%.
If it breaks, he expects altcoins to “rally harder than you ever could have imagined.”
Fellow analyst Willy Woo is cautioning his crew of 113,000 followers to watch out for the vast majority of altcoins, which he says lack the liquidity necessary for them to be solid investments.
“HODLing altcoins in 2017 use to be speculating on a technological dream while driving a Lambo.
HODLing altcoins in 2019 is like reading through regulatory compliance documents for a large enterprise while checking you have enough change for a bus to get home.”
Daily analyst Josh Rager tells his 59,000 followers that Bitcoin’s price remains king.
“Alts are directly correlated to Bitcoin.
If the price goes south, diversifying into alts will only make things worse. If you want hedge, learn how to use futures or options to your advantage.
Diversification in crypto is not strategy – majority of portfolio should be BTC.”
In the short term, analyst Filbfilb tells his collective following of 39,000 on Telegram and on Twitter that he thinks Bitcoin could suffer a further breakdown.
“Looks like we need to go lower. Getting signs to flip short but waiting on candle closes.”
Right now, Bitcoin is down 1.28% at $8,703, according to CoinMarketCap at time of publishing.


actions and are drawn to His love. When we act out of the places in our hearts that are still selfish and untransformed, we are the ones on display for the world. The greatest damage to God’s name is done by Christians acting in ways that do not reflect His character.
When have your actions hurt God’s reputation instead of helping it?
When have your actions called attention to the power, love, and character of God instead of to yourself?
God calls us to live so differently from the people around us that they take notice. He calls us to live the way Jesus did. Daniel, Hananiah, Mishael, and Azariah had God’s name embedded in their own names. When we make a pledge to follow Jesus, He gives us the name “Christian” to wear—a title that has the very name of Christ embedded in it. If we allow Him to continually transform our hearts and actions, we will bring honor and praise not to ourselves but to Christ, for His name’s sake.
Pray About It
Unchanging God, help us to change so that we may reflect Your love and compassion. If there are parts of our lives that are not in step with the name of Christ, which we are given the privilege of wearing, help us to recognize them and turn them over to You. We praise You for the ways You have been at work, making us like Jesus. We still need Your help! Make us over into Your image so that people will see You in us and praise Your name. Lead us in paths of righteousness, not for our sake, but for the sake of Your name. Amen.
Act on It
Think of your life as a commercial for God’s loving, transforming action. How are you doing at endorsing the product of His grace? Would people want to buy the product based on the way you treat them? Based on your actions and relationships? If there is a part of your life that does not reflect integrity or consistency with the name of Christ, how can you work on it this week?
