Provides a function that abstracts the HTTP session.
This function issues session ID to identify the session,
and the session is tracked using the cookie (NABLARCH_SID
(changeable)).
It provides a function called a session store for each session ID to read and write to a save destination.
The value read from and written to the session store for each session ID by this function is called a session variable.
Flow of a simple process is shown in the figure below.
- The request process of Session Variable Store Handler loads the session variable from the session store based on the session ID obtained from the cookie.
- Reads from/writes to session variable using SessionUtil from business action.
- The response process of Session Variable Store Handler saves the session variables in the session store.
- Configure session variable in request scope so that it can be referenced in JSP. (Do not configure if a value with the same name already exists in the request scope.)
Important
When using this function, the following functions are deprecated because of duplication of applications.
- hidden encryption
- Session Concurrent Access Handler
- API to access the session scope of ExecutionContext.
Tip
The cookie ( NABLARCH_SID
) used in this function is completely different from the JSESSIONID used for tracking the HTTP session.
Tip
Starting from Nablarch 5u16, you can choose the location for storing the expiration date of the session store other than HTTP sessions.
Tip
UUID is used for the session ID used in the cookie ( NABLARCH_SID
).
7.17.1. Function overview¶
<IP_ADDRESS>. Save destination of session variables can be selected¶
Save destination of the session variable can be selected according to the usage.
The following three types of stores are provided as standard.
For the features and selection criteria of the session store, see Features and selection criteria of session store.
Also, Redis can be used as a store destination by using Redis Store (Lettus) Adapter.
<IP_ADDRESS>. Serialization mechanism for session variable can be selected¶
The serialization mechanism when saving session variables in session store can be selected from the following. For details of each function, refer to the linked Javadoc.
7.17.2. Module list¶
<dependency>
<groupId>com.nablarch.framework</groupId>
<artifactId>nablarch-fw-web</artifactId>
</dependency>
<!-- Only when using DB store -->
<dependency>
<groupId>com.nablarch.framework</groupId>
<artifactId>nablarch-fw-web-dbstore</artifactId>
</dependency>
7.17.3. Constraints¶
<IP_ADDRESS>. Save target must Java Beans object that can be serialized¶
Object to be saved in the session store must be a serializable Java Beans object.
The property type of the object must be a Java basic type or a Java Beans object that can be serialized. Arrays and collections can also be used for properties.
7.17.4. How to use¶
<IP_ADDRESS>. Configure for using session store¶
To use session store, configure SessionManager in the component definition in addition to configuring Session Variable Store Handler.
The following is a configuration example when all the save destinations provided as standard are used.
<!-- Configure with the component name "sessionManager" -->
<component name="sessionManager" class="nablarch.common.web.session.SessionManager">
<!--
Store name used by default if a save destination is not specified explicitly
-->
<property name="defaultStoreName" value="db"/>
<!-- Add components according to the save destination used in the application -->
<property name="availableStores">
<list>
<!-- HIDDEN store -->
<component class="nablarch.common.web.session.store.HiddenStore">
<!-- See Javadoc for details of the configuration value -->
</component>
<!-- DB store -->
<component-ref name="dbStore" />
<!-- HTTP session store -->
<component class="nablarch.common.web.session.store.HttpSessionStore">
<!-- See Javadoc for details of the configuration value -->
</component>
</list>
</property>
</component>
<component name="dbStore" class="nablarch.common.web.session.store.DbStore">
<!-- See Javadoc for details of the configuration value -->
</component>
<!-- DB store initialization configuration -->
<component name="initializer"
class="nablarch.core.repository.initialization.BasicApplicationInitializer">
<property name="initializeList">
<list>
<!-- Other components are omitted -->
<component-ref name="dbStore" />
</list>
</property>
</component>
When using DB store, a table must be created in the database to store the session variables.
The definition of the table to be created is shown below.
- USER_SESSION table
Column name Data type SESSION_ID(PK) java.lang.String SESSION_OBJECT byte[] EXPIRATION_DATETIME java.sql.Timestamp
SESSION_ID should be defined as VARCHAR instead of CHAR as it may not work properly in Oracle.
The table name and column name can be changed. To change, define the components of UserSessionSchema to DbStore.userSessionSchema.
<property name="userSessionSchema">
<component class="nablarch.common.web.session.store.UserSessionSchema">
<!-- See Javadoc for details of the configuration value -->
</component>
</property>
Tip
When DB store is used, session information may remain in the table when the browser is closed. Therefore, expired session information must be deleted regularly.
<IP_ADDRESS>. Hold the input information between the input-confirm-complete screens¶
To retain the input information between the input-confirm-complete screen, use the session store depending on whether screen operations on multiple tabs are allowed.
- When screen operations on multiple tabs are not allowed
- Hold session variables in a table on the database using the DB store.
- When screen operations on multiple tabs are allowed
Hold session variables in the client using HIDDEN store.
When using HIDDEN store, use hiddenStore tag in JSP of input/confirmation screen as shown below.
<n:form> <!-- Configure the value of parameterName property of HiddenStore defined in the component configuration file to the name attribute --> <n:hiddenStore name="nablarch_hiddenStore" /> <!-- Other tags are omitted --> </n:form>
Implementation example of session store between input-confirm-complete is shown below.
Tip
Object (Entity) for executing business logic should be stored in the session store instead of Form.
By storing Entity, business logic can be executed immediately with the object acquired from the session store. As a result, unnecessary processes can be prevented from being mixed in the business logic, and enhancement of cohesiveness at the source can be expected.
On the other hand, storing a Form increases the possibility that a tightly coupled source will be created by inducing the passing of data by the Form and incorporating unnecessary data conversion processing in the business logic.
Form needs to be validated as it accepts external input values, but before validation, Form is in a state of holding unreliable values. Therefore, from the security perspective, since data stored in the session store will have a long lifetime, the goal is also to retain the safest data possible and reduce the risk of embedding vulnerabilities.
<IP_ADDRESS>. Holds credentials¶
Use DB store to retain credentials.
Implementation example of session store during login/logout is shown below.
- Login to the application
// Change session ID before login SessionUtil.changeId(ctx); // Regenerate CSRF token (If you are using the CSRF Token Verification Handler) CsrfTokenUtil.regenerateCsrfToken(ctx); // Save login user information in session store SessionUtil.put(ctx, "user", user, "db");
Important
If all of the following conditions are met, a CSRF token must be regenerated at login.
- Using the CSRF Token Verification Handler
- Only change session ID at login (keep session information)
See Regeneration of CSRF tokens for more information.
- Logout from the application
// Invalidate the entire session store SessionUtil.invalidate(ctx);
<IP_ADDRESS>. Refer to the session variable value from JSP¶
The value of session variable held in the session store can be referenced from JSP using the same procedure as the normal request scope and session scope.
Important
If a value with the same name already exists in the request scope, the value of the session variable cannot be referenced from JSP. Therefore, configure a name that does not overlap with the request scope in session variable.
<IP_ADDRESS>. Specify the transition destination screen when the value does not exist in the session variable¶
Session variables always exist in normal screen transitions, but in some cases, session variables that originally existed may not be accessible due to incorrect screen transitions being performed using the back button of the browser. Since an exception indicating that the session variable does not exist ( SessionKeyNotFoundException ) is thrown, transition to an arbitrary error page is possible by catching this exception.
The realization method is shown below.
- Transition to a common error page in the system
When transitioning to a common error page in the system, catch the exception in the handler and specify the transition destination.
- Implementation examples
public class SampleErrorHandler implements Handler<Object, Object> { @Override public Object handle(Object data, ExecutionContext context) { try { return context.handleNext(data); } catch (SessionKeyNotFoundException e) { // Catches the exception indicating that the session variable does not exist // and returns the error page indicating the incorrect screen transition throw new HttpErrorResponse(HttpResponse.Status.BAD_REQUEST.getStatusCode(), "/WEB-INF/view/errors/BadTransition.jsp", e); } } }
- Specify the transition destination for each request
When switching the transition destination for each request, specify the transition destination using OnError Interceptor. Note that the transition destination can be changed for only some of the requests by using it together with the transition to a common error page in the system mentioned above.
- Implementation examples
// Specify the transition destination for each request // by specifying the exception indicating that the session variable does not exist // in the target exception @OnError(type = SessionKeyNotFoundException.class, path = "redirect://error") public HttpResponse backToNew(HttpRequest request, ExecutionContext context) { Project project = SessionUtil.get(context, "project"); // Process is omitted }
7.17.5. Expansion example¶
<IP_ADDRESS>. Add the save destination of session variables¶
The following steps are required to add the save destination for session variables.
- Create a class by inheriting SessionStore for supporting the save destination to be added.
- Add the component definition of the created class to SessionManager.availableStores.
7.17.6. Features and selection criteria of session store¶
The save destination of session variables that can be used by default is as follows.
- DB store
Save destination: Database tableFeatures: - Session variables can be restored even if the application server is stopped due to rolling maintenance.
- Does not squeeze the heap area of the application server.
- If the processing of the same session is executed by multiple threads, (the one written last takes precedence. (Data of previously saved session will be lost)
- HTTP session store
Save destination: Application server heap area(depending on the application server configuration, it may be saved in a database or file.)Features: - It is suitable for holding information such as credentials that are frequently used in the entire application.
- Since information is maintained on a per AP server basis, ingenuity is required when performing scale-out.
- Saving a large amount of data such as the input contents of the screen may burden the heap area.
- If the processing of the same session is executed by multiple threads, it will written later. (Data of previously saved session will be lost)
Based on the above, the selection criteria for each session store are shown below.
| Application | Session Store |
|---|---|
| Hold input information between input-confirm-complete screens (screen operations on multiple tabs not allowed) | DB store |
| Hold input information between input-confirm-complete screens (screen operations on multiple tabs allowed) | HIDDEN store |
| Hold credentials | DB store or HTTP session store |
| Hold the search conditions | Not used [1] |
| Hold the search results list | Not used [2] |
| Hold screen display items such as select boxes | Not used [3] |
| Hold error message | Not used [3] |
| [1] | Except for credentials, the session store is not intended to hold data spanning multiple functions. Design and implement the session store according to the requirements of the application, such as holding the URL in the local storage of the browser for search. |
| [2] | Large amounts of data such as list information may burden the storage area, so do not store it in the session store. |
| [3] | (1, 2) Values used for screen display can be transferred using the request scope. |
Tip
As for Redis Store (Lettus) Adapter, its features are the same as the DB store, only the destination is different.
7.17.7. How to manage the expiration date¶
Session expiration date is stored in an HTTP session by default. You can store the session expiration date in the database by changing the setting.
See Save the expiration date in the database for details.
Also, the expiration date can be stored in Redis if using Redis Store (Lettus) Adapter.
Tip
See Making Web Applications Stateless for the significance of storing the expiration date in the database.


DRAFT: sketch of untested code.
FIXME: I have not gotten the current Obc-3 to compile under Darwin (macOS).
Modules in this directory are being ported to the Obc-3 compiler and should be compiled with the -07
option.
Debian systems
sudo apt install build-essential autotools automake autoconf git
sudo apt install ocaml
sudo apt install libgtksourceview2.0-dev
git clone git@github.com:Spivoxity/obc-3
I am currently running into issues compiling these modules on macOS. Not sure if this is specific to my Mac (it is rather vintage) or due to problems with compiler flags. I suspect my Makefile is not calling the right options for macOS compilation.

This driver implements support for access to spatial tables in the IBM DB2 for Linux, Unix and Windows (DB2 LUW) and the IBM DB2 for z/OS relational databases using the default ODBC support incorporated into GDAL.
The documentation for the DB2 spatial features can be found online for DB2 for z/OS and DB2 LUW
This driver is currently supported only in the Windows environment.
orDB2ODBC:database=dbname;DSN=datasourcename
The following custom parameters can also be used in the following syntax:DB2ODBC:database=dbname;DRIVER={IBM DB2 ODBC DRIVER};Hostname=hostipaddr;PROTOCOL=TCPIP;port=db2port;UID=myuserid;PWD=mypw
The parameter names are not case sensitive in the connection strings.
Specifying the Database parameter is required by the driver in order to select the proper database.
By default the DB2 driver will only look for layers that are registered in the DB2GSE.ST_GEOMETRY_COLUMNS metadata table.
The DB2 driver passes SQL statements directly to DB2 by default, rather than evaluating them internally when using the ExecuteSQL() call on the OGRDataSource, or the -sql command option to ogr2ogr. Attribute query expressions are also passed directly through to DB2. It's also possible to request the OGR DB2 driver to handle SQL commands with the OGR SQL engine, by passing "OGRSQL" string to the ExecuteSQL() method, as the name of the SQL dialect.
The DB2 driver in OGR supports the OGRLayer::StartTransaction(), OGRLayer::CommitTransaction() and OGRLayer::RollbackTransaction() calls in the normal SQL sense.
This driver doesn't support creating new databases. Use the DB2 command line or tools like IBM Data Studio to create the database. It does allow creation of new layers within an existing database.
By default the DB2 driver doesn't add spatial indexes to the tables during the layer creation. Spatial indexes should be created using the DB2 CREATE INDEX command.
Creating a layer from an OGR data source
ogr2ogr -overwrite DB2ODBC:database=sample;DSN=sampDSN zipcodes.shp
Connecting to a layer and dump the contents
ogrinfo -al DB2ODBC:database=sample;DSN=sampDSN;tables=zipcodes


Another record month for sports betting in NJ: $487M in bets
by WAYNE PARRYATLANTIC CITY, N.J. (AP) - New Jersey’s sports betting industry set another monthly record in October for the amount bet as gamblers plunked down close to a half-billion dollars while baseball’s playoffs and World Series, football, basketball and hockey were all on the betting board.
Figures released Thursday by the state Division of Gaming Enforcement show the state’s casinos and horse tracks took $487 million in sports bets last month.
That eclipsed the previous monthly record of $445 million set in September.

It was the latest indication that New Jersey, which cleared the way for legal sports betting nationwide by winning a U.S. Supreme Court case last year, is a real threat to take over leadership of the U.S. sports betting market from Nevada.
“Sports wagering is certainly claiming a seat at the table, with its October revenue share at 7% of total gaming revenue, compared to 2.96% in October 2018,” said Rummy Pandit, executive director of the Lloyd Levenson Institute at Stockton University.
Jeff Gural, who operates the Meadowlands Racetrack in East Rutherford, just outside New York City, said New Jersey’s success is due in part to New York officials’ failure to approve mobile sports betting; bets can only be made in person at upstate New York casinos.
“It’s clearly a factor of New York sitting on its hands,” Gural said. “It’s not going to last forever.”
The Meadowlands track, which is affiliated with the Fan Duel and PointsBet sports books, dominates New Jersey’s sports betting market, due in large part to its proximity to the country’s largest city.
It earned nearly $25 million in sports betting revenue in October after paying out winning bets and other expenses, up from $3.5 million in Nov. 2018. Resorts Digital, affiliated with DraftKings, was next at $10.5 million in revenue.
Monmouth Park Racetrack earned $2.8 million in sports betting revenue and the Ocean Casino Resort took in $2.3 million.
October also was a great month for internet gambling, which was up 69% from a year ago to $45.2 million.
The figures show just how reliant Atlantic City’s casinos have become on the extra money from sports bets and online bets. Without those two, the casinos saw their revenue rise by less than 1% to $202 million.
Overall, including casino games, internet gambling and sports betting, total gambling revenue in the state was up 22.9% to $293.8 million.
Excluding sports betting, the casinos’ collective revenue for in-person and internet gambling was up 13.6% to $266.2 million.
Ocean had the largest monthly increase, up almost 47% from a year ago to $21.3 million.
Golden Nugget was up nearly 22% to $31.9 million. Hard Rock was up 16.4% to $28.2 million, and Borgata was up 10.5% to $61.1 million.
Caesars was up 7.8% to $21.7 million, and Harrah’s was up 1.2% to $24.1 million.
Resorts was down 10.6% to $12.3 million; Tropicana was down 8.9% to $26.3 million; and Bally’s was down 6.2% to $13.8 million.

Truth, Geometry, Algebra
1. According to H.S.M. Coxeter and Richard J. Trudeau"There is a pleasantly discursive treatment of Pontius Pilate's unanswered question 'What is truth?'."

Summary of the story thus far:
Diamond theory and Coxeter theory are to some extent analogous-- both deal with reflection groups and both have a visual (i.e., geometric) side and a verbal (i.e., algebraic) side. Coxeter theory is of course highly developed on both sides. Diamond theory is, on the geometric side, currently restricted to examples in at most three Euclidean (and six binary) dimensions. On the algebraic side, it is woefully underdeveloped. For material related to the algebraic side, search the Web for generators+relations+"characteristic two" (or "2") and for generators+relations+"GF(2)". (This last search is the source of the Grams reference in 2.2.2 above.)Update of Feb. 21, 2010--
Reflections
From the Wikipedia article "Reflection Group" that I created on Aug. 10, 2005– as revised on Nov. 25, 2009–
|
Historically, (Coxeter 1934) proved that every reflection group [Euclidean, by the current Wikipedia definition] is a Coxeter group (i.e., has a presentation where all relations are of the form ri2 or (rirj)k), and indeed this paper introduced the notion of a Coxeter group, while (Coxeter 1935) proved that every finite Coxeter group had a representation as a reflection group [again, Euclidean], and classified finite Coxeter groups. Finite fields
When working over finite fields, one defines a "reflection" as a map that fixes a hyperplane (otherwise for example there would be no reflections in characteristic 2, as −1=1 so reflections are the identity). Geometrically, this amounts to including shears in a hyperplane. Reflection groups over finite fields of characteristic not 2 were classified in (Zalesskiĭ & Serežkin 1981). |

Enter your current altitude, orbital velocity, and periapsis distance into the calculator at right. Then, enter the apoapsis distance you want after aerobraking. The calculator will find a manoeuver to get you there. Units: m, km or Mm
The solution found by the calculator is in the form of an orbital manoeuver. Point your craft at the angle given by the calculator and thrust until the orbit periapsis matches that given by the solution. Your orbital velocity should not significantly change.
Note on the angles: Angles are measured from the top of the navball. The direction in which to thrust will always lie between the prograde and retrograde markers. The heading in which to thrust is the same as your prograde / retrograde vectors (i.e. in the plane of orbit.)
Before running the calculator, adjust your orbit so that the periapsis is somewhere in the atmosphere of the target body. Doing this will help the calculator find a manoeuver with a lower delta-v.
The calculator will probably not work for ships with lift surfaces, because the lift force depends on the craft's orientation in the atmosphere. Lift forces are not considered.
Sometimes, when coming out of timewarp, the periapsis will jump around a bit, potentially messing up the aerobraking manoeuver. If this happens, just re-run the calculator with the new orbit data to determine the required course correction.
This calculator searches for constant-velocity manoeuvers that, after aerobraking, result in an orbit with the desired apoapsis. This is done by fixing the current altitude and velocity, and varying the periapsis of the orbit. The periapsis resulting in the desired orbit is then calculated.
Given a current altitude, orbital velocity, and periapsis, we have enough information to resolve the orbit of the ship (there are some ambiguities in orientation, but they do not matter for this problem). The point of intersection of this orbit with the atmosphere and the velocity of the ship at that point are calculated. Using these data, the trajectory in the atmosphere is determined using numerical methods. The velocity at which the ship escapes the atmosphere is found, and used to compute the new orbit.


Hi!
First of all thank you for Better Battlog. It is essentiel for BF3 Players, thanks!
My problem:
I don't see my Jet and Chopper Service Stars on my Vehicles Page:
http://battlelog.battlefield.com/bf3/soldier/doping1/vehicles/351449751/pc/
It says "Shortcut Kit used" instead of the Service Stars. But I did not buy any Shortcut Bundles or something, played those up legitimately.
Also when I kill somebody ingame with the Jet or the Chopper, the enemy does not see my Service Stars in this vehicle while "deathcam" either.
After a Match when the Scoreboard appears, I can display my Service Stars in the Vehicles Tab. Dogtags are also working.
Any ideas?
Peace.

Definitions and naming conventions for the members of the JAVA classes
A java program may contain many classes of which only one class will have a main method. Class will contain data members and methods that operate on the data members of the class. To write a Java program, we first need to define classes and then put them together. Generally a standard java program consists of following blocks as shown in below figure.
Structure:
Package list; public Class <class name> { Data members; Constructor functions; User-defined methods; public static void main (String arguments[]) { Block of statements; } }
– https://www.geeksforgeeks.org/structure-members-java-program/#post-188134
Java Naming conventions
Java naming convention is a rule to follow as you decide what to name your identifiers such as class, package, variable, constant, method, etc.
Variable
- It should start with a lowercase letter such as id, name.
- It should not start with the special characters like & (ampersand), $ (dollar), _ (underscore).
- If the name contains multiple words, start it with the lowercase letter followed by an uppercase letter such as firstName, lastName.
- Avoid using one-character variables such as x, y, z.
Class
- It should start with the uppercase letter.
- It should be a noun such as Color, Button, System, Thread, etc.
- Use appropriate words, instead of acronyms.
Interface
- It should start with the uppercase letter.
- It should be an adjective such as Runnable, Remote, ActionListener.
- Use appropriate words, instead of acronyms.
Method
- It should start with lowercase letter.
- It should be a verb such as main(), print(), println().
- If the name contains multiple words, start it with a lowercase letter followed by an uppercase letter such as actionPerformed().
Package
- It should be a lowercase letter such as java, lang.
- If the name contains multiple words, it should be separated by dots (.) such as java.util, java.lang.
Constant
- It should be in uppercase letters such as RED, YELLOW.
- If the name contains multiple words, it should be separated by an underscore(_) such as MAX_PRIORITY.
- It may contain digits but not as the first letter.

[gecode-users] NaryUnion, infinite loop
Christian Schulte
cschulte at kth.se
Fri Mar 30 14:34:46 CEST 2012
Hi,
The problem is really that both iterators must allocate from the same
region. You should try to avoid the assignment operator for NaryUnion (I
should have not implemented it in the first place, because I know it is
troublesome). Normally there should be no reason to use an assignment
operator, just initialize when you create or use the copy constructor.
Sorry
Christian

I am director of the Newman Institute for Catholic Thought & Culture and Assistant Professor of English and Humanities at St. Gregory the Great Seminary with offices in Lincoln, NE. Since 2010 I have been working on the scholia (ancient commentaries) to the Greek lyric poet Pindar (c.518-c.438 BC). That project has had many iterations, false starts, and break throughs. Along the way I realized when working with a corpus this big and aiming for maximum accessibility that, while I am still working to produce an updated version of A.B. Drachmann's 3-volume edition of the Pindar Scholia (1903-1927), the end goal is a Pindaric multitext (with both digital UI & print options) composed of various manuscripts, editions, metrical notations, translations, scholia, commentary, and scholarship inspired by the greatest of lyric poets.

BSNL to float tender for 50K 4G line equipment
New Delhi: State-run BSNL will float a 4G tender by November-end to roll out new lines up to 50,000, sources said.
The Bharat Sanchar Nigam Limited (BSNL), which received a fresh lease of life with the Cabinet approving its revival plan in October, will be floating a tender in November-end for 4G expansion at up to 50,000 sites, said the sources adding with the aim of starting the service by June 2020 if it receives the spectrum by December end.
The turnaround plan of government included the allotment of spectrum for 4th-generation or 4G services at 2016 prices to BSNL/MTNL with costs to be borne by the government.
“We expect 4G spectrum by the this year’s end. We will float a 50,000 e-nodes capacity tender next month. Our initial goal is to be able to do 50,000 sites from this tender – 30,000 by upgradation and 10,000, for which we have already placed the order.
“In 18 months, 100,000 4G sites should be operational,” PK Purwar, BSNL Chairman & Managing Director, had earlier told IANS.
By June 2020, BSNL’s target was to be able to use the existing sites, which could be upgraded, he said. “Our target is to make 70,000-80,000 BSNL 4G s ites operational in the next 15 months,” Purwar had said.
BSNL which is going to see reviving fortunes with the 4G spectrum allocation and an overwhelming 80,000 employee opting for the VRS, is depending on t he early roll out of its 4G service to be in contention and to cover up for t he delay of 2 years in 4G services vis-a-vis its rivals like Jio, Airtel, an d Vodafone Idea.
On Wednesday, Telecom Minister Ravi Shankar Prasad said in Lok Sabha The government would revive debt-laden telecom operator BSNL Ltd and will work on making it profitable.
To trim mounting losses in BSNL, the government in October had announced a revival package that included the merger of Mahanagar Telephone Nigam Ltd (MTNL) with the former. Until the proposed merger, MTNL will operate as a sub sidiary of BSNL.
The revival package also included raising sovereign bonds worth Rs 15,000 crore, monetising assets amounting to Rs 38,000 crore, and a voluntary retirement scheme (VRS) for employees.
Of the 1 lakh eligible for VRS, over 80,000 employees of BSNL have so far opted for the scheme, according to a news agency report. The effective date of voluntary retirement under the present scheme is January 31, 2020.
BSNL estimates savings of Rs 7,000 crore in wages if 70,000-80,000 employees choose the scheme. (IANS)

Aegisub / Video
Aegisub isn't a video (or media) player, but it still supports loading and working with video in various ways. This page is a reference of how Aegisub's loading and handling of video works; for a gentler introduction on how to just get things to display properly you may want to read the Typesetting Tutorial or Visual Typesetting pages.
Opening video
To load a video file, go to the Video menu and press Open video file. What video files you can open depends on your video provider. To use a dummy (mockup, blank) video, press Use dummy video.
Supported formats
Aegisub normally uses FFMS2 to open video, which supports opening nearly all common A/V formats, and many uncommon ones. For a full list of codecs supported, see FFmpeg or Libav documentation. Note that FFMS2 current has issues with interlaced H.264.
On Windows, Avisynth can be used instead of FFMS2. When opening via Avisynth, Aegisub will try several source functions to find the best choice:
- Import() - Avisynth builtin function. Used to load Avisynth scripts, never used for anything else.
- AviSource() - Avisynth builtin function. AviSource uses the system's Video for Windows (VfW) decoder to open the video, which for some esoteric formats may be the best or only way to open a file. Only supports .avi files, for obvious reasons. If AviSource cannot open a file, DSS2 is tried, followed by DirectShowSource.
- MPEG2Source() - Only used to load .d2v files (DVD2AVI project files; otherwise known as indexed .VOB's ripped from DVD's). Tries to use neuron2's DGDecode to open the file; if Aegisub can't find or load that it'll try the old mpeg2dec3.dll instead; if that too fails, returns an error. This is the most reliable way to open DVD video in Aegisub.
- DSS2() - Tries to find, load and use Haali's DirectShowSource2 plugin (comes with the Haali Media Splitter package and with the CCCP; the Avisynth plugin is avss.dll, you need to manually put it somewhere where Aegisub or Avisynth can find it, see below). That will in turn try to use your computer's DirectShow environment to open the file. Theoretically any file renderable by DirectShow should be supported, but since you are at the mercy of third-party splitters and decoders, your mileage may vary. As a rule of thumb, if it's playable in Windows Media Player, Aegisub should be able to load it. Do note that DSS2 converts variable framerate files to constant. Usually this is what you want and expect but if you're doing proper VFR subtitles, it isn't.
- DirectShowSource() - Uses DirectShowSource() (which ships with Avisynth) to try to load the file. Basically the same as DSS2, but far less reliable and it doesn't convert VFR to CFR. Warning: DSS is known to have problems with frame-accurate seeking. Do not use it if you can avoid it.
Note that VFR is not supported by the Avisynth provider. In some cases loading external timecodes may work, but in practice it will often result in a broken mess.
Aegisub will look for Avisynth plugins in its ?data directory (generally the folder where aegisub32.exe is, on Windows). You can also put them directly in your Avisynth plugins folder to get them autoloaded.
Dummy video
Aegisub also supports providing a bogus video surface for you to render subtitles on without having any actual video loaded. The dummy video dialog box looks like this:
Resolution
The resolution of the dummy video in pixels. There are a few pre-defined choices in the dropdown menu; you can also specify the size yourself. Note that since the dummy video is RGB there are no particular restrictions with regards to odd widths/heights.
Colour
The colour of the video surface. The color is solid by default; tick the box "checkerboard pattern" if you want some more variation.
Frame rate
Determines how long each frame is displayed by setting the number of frames per second (fps). Note that it is in fact possible to load VFR timecodes with dummy video.
Duration
The duration of the video in frames. Below this number is shown the resulting duration in hours/minutes/seconds.
Playing video
Aegisub does support playing back video, but it has been widely debated if it is a misfeature or not.
Before you press the "play" button
Think it through. Do you really want to play the video? (Hint: the answer is "no", you don't want to do that, at least not in Aegisub.) If you're trying to check if a subtitle matches up to something in the video, wouldn't it be easier to just step through the video frame-by-frame with the arrow keys? If you're proofwatching, it would be a better idea to watch it in a player your viewers might actually use.
To conclude: in real world situations, you will never need to play the video from inside Aegisub. The mantra is: Aegisub isn't a media player; if you want a media player use a media player. Nonetheless, Aegisub does make a reasonable effort to support reliable video playback and in practice it will usually work fine.
Note that audio has to be explicitly loaded for Aegisub to play it while playing video. If you find this bothersome, there is an option to automatically open audio whenever a video file is opened.
Keyframes
A brief, highly simplified explanation of what a keyframe is, for the people who missed Video 101:
Modern video codecs compress video by storing as little information as possible. Instead of storing all frames in full (like a large amount of JPG pictures), they take occasionally take a keyframe, which is stored fully, and for each frame after that until the next keyframe, they only store what changed in the picture since the last frame. Hence, to seek to a given frame the decoder needs to find the previous keyframe and decode all frames between that frame and the sought one, which means seeking to keyframes is faster than to other frames. Keyframes are interesting mostly for scene timing reasons, because they usually appear at scenechanges. The first frame in a scene is almost invariably a keyframe, but beware - far from every keyframe is a scenechange! Most encoders insert a keyframe at least once every 250-300 frames, even if there hasn't been a scenechange.
Aegisub uses keyframe data at several places in the program. They are drawn as black lines on the video seek bar, and (by default) also displayed in the audio waveform/spectrum analyzer.
Loading and saving of keyframe data
When opening video through FFMS2, Aegisub supports reading keyframe data from most file formats, while the Avisynth provider only supports reading keyframes from AVI. If you are using a video format which keyframes can't be read from, you can still load keyframe data separately. Aegisub currently supports reading from several formats: its own keyframe file format (see specification below), XviD first-pass files, DivX first-pass files, and x264 first-pass files.
Even if keyframes can be read from the file it is sometimes useful to override them with external keyframes. Using XviD first-pass .stat files for audio timing is fairly popular, as XviD's keyframe choices correlate unusually well with scene changes.
Aegisub can also write the currently loaded keyframe data to a keyframes file, which can be useful to avoid passing video files around in certain situations (audio timing for example).
Keyframe file specification
A keyframes file is a plain ASCII-encoded text file; both \n and \r\n is
understood to mean a linebreak. Syntax example:
# keyframe format v1
fps 0
0
30
70
82
130
131
The first line is the format specification; the string
# keyframe format v1
. The second line contains the FPS of the video used to
generate the keyframe data; however no programs (Aegisub included) actually
support this and so it is typically just 0
. Finally, after the fps line
follows an arbitrary number of long integers (one per line), each representing
the frame number of a keyframe. The frame numbers are zero-indexed; i.e. the
first frame of the video is frame number 0.
Variable framerate video
Aegisub supports loading and working with variable framerate video. The how's and why's of VFR is far outside the scope of this manual (see for example the VFR thread on AnimeSuki or the Avisynth manual page for more information about VFR), but we will cover what you need to know about how Aegisub handles it.
Timecodes
Loading of Matroska timecode files (v1 and v2) is supported and useful if you have a VFRaC (Variable FrameRate assumed Constant; for example the frames of an VFR MKV stored in an AVI at a constant FPS, see the VFR thread linked above for details) video file but want the subs to sync to it. If you load a VFR file, Aegisub will automatically read the timecodes from it directly.
VFR and hardsubbing
As long as you're not encoding with GDSMux, the encoding environment your subtitling filter is working in (i.e. Avisynth, VirtualDub or mencoder) will assume that the world is CFR, and hence the input file is VFRaC. This is obviously a problem since it messes up subtitle synchronization. Aegisub provides a way around this through the Framerate Transformation export filter, which takes the framerate of the VFRaC input file and the timecodes, and then changes every time code and override tag in the script so it can be hardsubbed on the VFRaC video and still sync up perfectly after timecodes are applied. To prepare a script for hardsubbing, make sure you have the timecodes loaded, then go to the File menu and press Export. Untick everything except the Transform Framerate filter. Choose the Variable output mode. It needs to know the FPS of the video you're going to hardsub the subtitles on; if you have video loaded Aegisub will assume that's it and insert it in the box for you. Note: if you have a Matroska or other VFR file loaded, remember that the FPS value Aegisub reports might not be the same as the one of the video you are going to hardsub the subtitles on.
Anamorphic video
OR: How to get your subtitles to not look stretched
The following paragraphs assumes that you have a working knowledge of what anamorphic video is and how aspect ratios work. If you feel unsure, you may want to consult a gentle but fairly complete introduction.
Image stretching and subtitle rendering
An anamorphic image needs to be stretched to the proper aspect ratio before it is presented to the viewer. On a computer, this is usually done by the video renderer, and thereby lies a problem. Most subtitle renderers (including VSFilter, the current "standard" renderer) do the subtitle drawing on the image before it is stretched, and since the renderer is not aware of any aspect ratio issues, the subtitles will be stretched along with the image when the video is displayed to the viewer, and therefore they will look stretched. Aegisub does its subtitle rendering this way as well (since that way it will be WYSIWYG with most players); you can test how it looks by using the "Override aspect ratio" in the video menu.
Compensating for the stretching
Fortunately it's easy to compensate for the stretching, since you know by how much the image will be stretched (since you know its original dimensions and the display aspect ratio). You just calculate how many percent the image will be stretched in either the X or the Y direction, and then set the ScaleX or ScaleY parameter in the style (or use the \fscx or \fscy overrides) to the same amount but in the other direction.
Example: we have a 704x480 image that we know will be displayed as 16:9 (or 1.7777...:1). If we assume that the player will stretch the width but leave the height untouched, this means that the new width will be: (16 / 9) * 480 = 853.333... which in percent is: 853.333... / 704 = 1.212121... i.e. 121%. Hence, to compensate for this horizontal (X-direction) stretch we set ScaleY in all our styles to 121% to stretch the subtitles by the same amount, and after rendering they now no longer look stretched.
OR we can do the stretching in the other direction, assuming that the player changes the height of the image instead. Assuming the same image: 704 / (16 / 9) = 396 which corresponds to: 396 / 480 = 0.825 or 82.5%, which means we can compensate for the vertical (Y) compression by setting ScaleX to 82.5%.
Caveats
Both of the above methods give the subtitles the proper aspect ratio, but depending on how the player does the stretching, you may get subtle variations in subtitle size. Aegisub (and indeed most video players and renderers) always changes the image width and never the height, except if you pick the "custom" aspect ratio and specify a resolution. Note that if you use the Matroska container, you may specify the display resolution directly, but player support of this varies.
Note that some odd subtitle renderers (most notably Media Player Classic's builtin renderer) are actually a part of the video renderer and will do the subtitle rendering after anamorphic stretching, resulting in stretched subtitles and much annoyance. With MPlayer's libass renderer, you can actually specify whether subtitles should be drawn before or after stretching by using the -vf parameter to move the subtitle renderer in the filter chain.

public class CH
extends java.lang.Object
This CH class implements the recursive formula of Caporaso-Harris in "Counting plane curves of any genus" for computing the number of nodal curves on the projective plane.
The user needs to enter the maximal degree and the maximal number of
nodes one wants to compute for the curves.
The program will print the number of degree d curves on the projective
plane with r nodes (strictly speaking, geometric genus (d-1)*(d-2)/2 - r)
which satisfy tangency conditions (alpha, beta) with a given line for
1) d = the biggest 5 positive integers less or equal to max degree
(5 is the default number and can be changed by modifying the instance
variable printLast),
2) all nonnegative integers r less or equal to max number of nodes,
3) all valid tangency conditions alpha and beta
(valid = satisfy I(alpha)+I(beta) = d).
alpha : tangency conditions at assigned points.
beta : tangency conditions at unassigned points.
beta = (beta_1, beta_2,....).
The output numbers will be located at output/CH
All terms in the generating series satisfying total degree <= 5 and
weighted degree <= 10 will be written in files at output/genFunCH.
wdeg r = 0, wdeg b = 2, wdeg c = 3, .....

The Best Graphics Card Under $250: Nvidia GeForce GTX 1660 vs. AMD Radeon RX 590
by Erik KainThis story was written in collaboration with Forbes Finds . Forbes Finds covers products and experiences we think you’ll love. Featured products are independently selected and linked to for your convenience. If you buy something using a link on this page, Forbes may receive a small share of that sale.
If you’re on a budget, the good news is that there are a ton of PC gaming components that are very powerful and fast at the lower end of the price scale. While it’s easy to spend hundreds (or even thousands) on GPUs, CPUs and RAM, budget-minded gamers can cobble together a gaming rig for a fraction of the price.
Take, for instance, the graphics card market. At the high end of the scale, you can easily drop more than $1,000 for a fancy Nvidia GeForce RTX 2080 Ti. Or you can spend $700 or more on an AMD Radeon VII or Nvidia GeForce RTX 2080 Super.
But there are much less expensive graphics cards out there. I’ll take a look at two of the top contenders in the upper end of this market. Yes, you can find graphics cards for less than a $100, but these are going to struggle with modern games, even at 1080p.
On Team Green, we have the Nvidia GeForce GTX 1660. On Team Red, we have the AMD Radeon RX 590. These are comparably priced cards with similar specs. Here’s how they compare:
Nvidia GeForce GTX 1660
- Architecture: Turing
- Transistor Count: 6.6 billion
- Base Clock: 1,506MHz
- Video Memory: 6GB GDDR5
- Memory Interface/Bandwith: 192-bit / 192GBps
- Power Draw: 130 W
AMD Radeon RX 590
- Architecture: Polaris
- Transistor Count: 5.7 billion
- Base Clock: 1,469MHz
- Video Memory: 8GB GDDR5
- Memory Interface/Bandwith: 256-bit / 256GBps
- Power Draw: 175 W
Performance
As you can see, the specs here are fairly comparable. Probably the biggest difference between the two is power consumption, with the RX 590 drawing a great deal more power than the GTX 1660.
But a performance gap does exist. Across multiple benchmarks at various PC-hardware sites, the GeForce GTX 1660 consistently outperforms the Radeon RX 590. At 1080p, this can be anywhere from just 3 or 4 frames-per-second, to as much as 10 to 15 frames-per-second. Things are a wash at 4K, but neither of these cards will perform well at that resolution to begin with, barely making it out of the 20-30 fps realm on most games (except for legacy titles).
Overall, the GeForce GTX 1660 outperforms the Radeon RX 590 across the board, with only a few exceptions. Meanwhile, the two cards curently retail at very similar price points, with the Radeon RX 590 falling significantly in price in recent months.
Right now, you can purchase this EVGA GeForce GTX 1660 on Amazon for $230 and the Sapphire Radeon RX 590 for $203. This gives the RX 590 a slight price edge over the GTX 1660, though less than $30 should probably not make much of a difference. The frame-rate advantage may not be much, but the GTX 1660 draws less power, which will save you money in the long haul.
As of this writing, however, the RX 590 comes with a free game, as well, and it’s a good one: Devil May Cry 5, one of my favorites of 2019, and just a brilliant action game all around. If you don’t already own it, that makes the RX 590 an even better purchase. That game still runs $59.99 on Steam, but you can find it for closer to $30 elsewhere. Still, that’s $30 off the price of the card, bringing the gap between the two to closer to $60 and making the RX 590 a great deal more attractive in the process.
Verdict
For my money, I'd go with the GeForce GTX 1660—but I already own Devil May Cry 5, so I may be biased. Either way you go, both cards will run most everything you throw at them at 1080p at over 60 frames-per-second. They’ll even handle some 1440p gaming well. Just don’t count on either for 4K. For 4K gaming you’ll need much beefier GPUs.


Yes; that is what the example program did.
The data are written as a stream of bytes. There are no gaps or markers that say where one value ends and another begins. The example program did this:
dataOut.writeInt( 0 ); dataOut.writeDouble( 12.45 );
An examination of the file shows the 12 bytes. Remember that dumps such as this print characters to show the pattern in one byte.
The six zeros at the beginning of the line mean the
the first byte shown is byte zero of the file.
The "f's" the end of the line show that some bytes
of the double
could also be interpreted
as characters.

Collecting data on any system with the goal of revealing something important or actionable about it.
Structures whose character depends not only on the properties of the individual elements of which they are composed and also the relative frequency of occurrence, but also on the manner by which the individual elements are connected with each other.
The scientistic attitude is decidedly unscientific, as it involves a mechanical and uncritical application of habits of thoughts to fields different from those in which they were formed.
Social theories are self-fulfilling. People adapt their behaviours to what you measure them for.

Quick Edit Dashboard Help
These are the price tier {{tiers[0].tierName}}’s prices for all the commodities stored in the system.
- From this page each commodity’s' {{tiers[0].tierName}} can be individually edited. The price change is previewed in the window below the price input. Previewed prices that are different from what is stored are indicated by a different background color. These changed prices will be updated and retained when Update button is clicked.
- Each column header displaying the commodity name is also a button that will display the Edit Prices editing form for that commodity.
- The input field is limited to keep the price within the display’s limits. Most commonly, 0.00 - 9.99 for a 3 digit display with decimal setting of 2.
- Clicking the Detail button will display the other price tier prices on this page as well. Clicking the Detail button again will toggle them off. Only displayed if more than one price tier.
- Clicking the Reset button will reset the prices to state at last update and clear all unsaved changes.
- Clicking the Refresh button will refresh the data from the server.
Changes are retained when Update button is pressed. Not reversible!
Quick Edit Dashboard
Edit Prices Form Help
- Each price for each price tier may be edited here.
- Each commodity can be selected from the tabs along the top.
- The {{tiers[0].tierName}} is derived from the Quick Edit Dashboard but may also be edited here. A change here will also update the amounts on the Quick Edit Dashboard.
- The commodity’s other price tiers’ prices are derived by adding the offset amount in the input field to the {{tiers[0].tierName}}.
- A negative amount in the offset input field results in a price lower than the {{tiers[0].tierName}} (A discount.)
- The offset input field amount will be limited according to the assigned displays’ capability. Most commonly, between 0.00 and 9.99 for a 3-digit display with a 2-digit decimal setting.
- The Reset button resets the form to it’s condition just after the last Update.
Price changes are not saved until the Update button is clicked here or back on the Quick Edit Dashboard. Not reversible!
