NAME
dbopen - database access methods
SYNOPSIS
#include <sys/types.h>
#include <limits.h>
#include <db.h>
#include <fcntl.h>
DB *dbopen(const char *file, int flags, int mode, DBTYPE type,
const void *openinfo);
DESCRIPTION
Note well:
This page documents interfaces provided in glibc up until version 2.1.
Since version 2.2, glibc no longer provides these interfaces.
Probably, you are looking for the APIs provided by the
libdb
library instead.
dbopen()
is the library interface to database files.
The supported file formats are btree, hashed and UNIX file oriented.
The btree format is a representation of a sorted, balanced tree structure.
The hashed format is an extensible, dynamic hashing scheme.
The flat-file format is a byte stream file with fixed or variable length
records.
The formats and file-format-specific information are described in detail
in their respective manual pages
btree(3),
hash(3),
and
recno(3).
dbopen()
opens
file
for reading and/or writing.
Files never intended to be preserved on disk may be created by setting
the
file
argument to NULL.
The
flags
and
mode
arguments are as specified to the
open(2)
routine, however, only the
O_CREAT,
O_EXCL,
O_EXLOCK,
O_NONBLOCK,
O_RDONLY,
O_RDWR,
O_SHLOCK,
and
O_TRUNC
flags are meaningful.
(Note, opening a database file
O_WRONLY
is not possible.)
The
type
argument is of type
DBTYPE
(as defined in the
<db.h>
include file) and
may be set to
DB_BTREE,
DB_HASH,
or
DB_RECNO.
The
openinfo
argument is a pointer to an access-method-specific structure described
in the access method's manual page.
If
openinfo
is NULL, each access method will use defaults appropriate for the system
and the access method.
dbopen()
returns a pointer to a
DB
structure on success and NULL on error.
The
DB
structure is defined in the
<db.h>
include file, and contains at
least the following fields:
typedef struct {
DBTYPE type;
int (*close)(const DB *db);
int (*del)(const DB *db, const DBT *key, unsigned int flags);
int (*fd)(const DB *db);
int (*get)(const DB *db, DBT *key, DBT *data,
unsigned int flags);
int (*put)(const DB *db, DBT *key, const DBT *data,
unsigned int flags);
int (*sync)(const DB *db, unsigned int flags);
int (*seq)(const DB *db, DBT *key, DBT *data,
unsigned int flags);
} DB;
These elements describe a database type and a set of functions performing
various actions.
These functions take a pointer to a structure as returned by
dbopen(),
and sometimes one or more pointers to key/data structures and a flag value.
- type
-
The type of the underlying access method (and file format).
- close
-
A pointer to a routine to flush any cached information to disk, free any
allocated resources, and close the underlying file(s).
Since key/data pairs may be cached in memory, failing to sync the file
with a
close
or
sync
function may result in inconsistent or lost information.
close
routines return -1 on error (setting
errno)
and 0 on success.
- del
-
A pointer to a routine to remove key/data pairs from the database.
-
The argument
flag
may be set to the following value:
-
- R_CURSOR
-
Delete the record referenced by the cursor.
The cursor must have previously been initialized.
-
delete
routines return -1 on error (setting
errno),
0 on success, and 1 if the specified
key
was not in the file.
- fd
-
A pointer to a routine which returns a file descriptor representative
of the underlying database.
A file descriptor referencing the same file will be returned to all
processes which call
dbopen()
with the same
file
name.
This file descriptor may be safely used as an argument to the
fcntl(2)
and
flock(2)
locking functions.
The file descriptor is not necessarily associated with any of the
underlying files used by the access method.
No file descriptor is available for in memory databases.
fd
routines return -1 on error (setting
errno),
and the file descriptor on success.
- get
-
A pointer to a routine which is the interface for keyed retrieval from
the database.
The address and length of the data associated with the specified
key
are returned in the structure referenced by
data.
get
routines return -1 on error (setting
errno),
0 on success, and 1 if the
key
was not in the file.
- put
-
A pointer to a routine to store key/data pairs in the database.
-
The argument
flag
may be set to one of the following values:
-
- R_CURSOR
-
Replace the key/data pair referenced by the cursor.
The cursor must have previously been initialized.
- R_IAFTER
-
Append the data immediately after the data referenced by
key,
creating a new key/data pair.
The record number of the appended key/data pair is returned in the
key
structure.
(Applicable only to the
DB_RECNO
access method.)
- R_IBEFORE
-
Insert the data immediately before the data referenced by
key,
creating a new key/data pair.
The record number of the inserted key/data pair is returned in the
key
structure.
(Applicable only to the
DB_RECNO
access method.)
- R_NOOVERWRITE
-
Enter the new key/data pair only if the key does not previously exist.
- R_SETCURSOR
-
Store the key/data pair, setting or initializing the position of the
cursor to reference it.
(Applicable only to the
DB_BTREE
and
DB_RECNO
access methods.)
-
R_SETCURSOR
is available only for the
DB_BTREE
and
DB_RECNO
access
methods because it implies that the keys have an inherent order
which does not change.
-
R_IAFTER
and
R_IBEFORE
are available only for the
DB_RECNO
access method because they each imply that the access method is able to
create new keys.
This is true only if the keys are ordered and independent, record numbers
for example.
-
The default behavior of the
put
routines is to enter the new key/data pair, replacing any previously
existing key.
-
put
routines return -1 on error (setting
errno),
0 on success, and 1 if the
R_NOOVERWRITE
flag
was set and the key already exists in the file.
- seq
-
A pointer to a routine which is the interface for sequential
retrieval from the database.
The address and length of the key are returned in the structure
referenced by
key,
and the address and length of the data are returned in the
structure referenced
by
data.
-
Sequential key/data pair retrieval may begin at any time, and the
position of the "cursor" is not affected by calls to the
del,
get,
put,
or
sync
routines.
Modifications to the database during a sequential scan will be reflected
in the scan, that is,
records inserted behind the cursor will not be returned
while records inserted in front of the cursor will be returned.
-
The flag value
must
be set to one of the following values:
-
- R_CURSOR
-
The data associated with the specified key is returned.
This differs from the
get
routines in that it sets or initializes the cursor to the location of
the key as well.
(Note, for the
DB_BTREE
access method, the returned key is not necessarily an
exact match for the specified key.
The returned key is the smallest key greater than or equal to the specified
key, permitting partial key matches and range searches.)
- R_FIRST
-
The first key/data pair of the database is returned, and the cursor
is set or initialized to reference it.
- R_LAST
-
The last key/data pair of the database is returned, and the cursor
is set or initialized to reference it.
(Applicable only to the
DB_BTREE
and
DB_RECNO
access methods.)
- R_NEXT
-
Retrieve the key/data pair immediately after the cursor.
If the cursor is not yet set, this is the same as the
R_FIRST
flag.
- R_PREV
-
Retrieve the key/data pair immediately before the cursor.
If the cursor is not yet set, this is the same as the
R_LAST
flag.
(Applicable only to the
DB_BTREE
and
DB_RECNO
access methods.)
-
R_LAST
and
R_PREV
are available only for the
DB_BTREE
and
DB_RECNO
access methods because they each imply that the keys have an inherent
order which does not change.
-
seq
routines return -1 on error (setting
errno),
0 on success and 1 if there are no key/data pairs less than or greater
than the specified or current key.
If the
DB_RECNO
access method is being used, and if the database file
is a character special file and no complete key/data pairs are currently
available, the
seq
routines return 2.
- sync
-
A pointer to a routine to flush any cached information to disk.
If the database is in memory only, the
sync
routine has no effect and will always succeed.
-
The flag value may be set to the following value:
-
- R_RECNOSYNC
-
If the
DB_RECNO
access method is being used, this flag causes
the sync routine to apply to the btree file which underlies the
recno file, not the recno file itself.
(See the
bfname
field of the
recno(3)
manual page for more information.)
-
sync
routines return -1 on error (setting
errno)
and 0 on success.
Key/data pairs
Access to all file types is based on key/data pairs.
Both keys and data are represented by the following data structure:
typedef struct {
void *data;
size_t size;
} DBT;
The elements of the
DBT
structure are defined as follows:
- data
-
A pointer to a byte string.
- size
-
The length of the byte string.
Key and data byte strings may reference strings of essentially unlimited
length although any two of them must fit into available memory at the same
time.
It should be noted that the access methods provide no guarantees about
byte string alignment.
ERRORS
The
dbopen()
routine may fail and set
errno
for any of the errors specified for the library routines
open(2)
and
malloc(3)
or the following:
- EFTYPE
-
A file is incorrectly formatted.
- EINVAL
-
A parameter has been specified (hash function, pad byte, etc.) that is
incompatible with the current file specification or which is not
meaningful for the function (for example, use of the cursor without
prior initialization) or there is a mismatch between the version
number of file and the software.
The
close
routines may fail and set
errno
for any of the errors specified for the library routines
close(2),
read(2),
write(2),
free(3),
or
fsync(2).
The
del,
get,
put,
and
seq
routines may fail and set
errno
for any of the errors specified for the library routines
read(2),
write(2),
free(3)
or
malloc(3).
The
fd
routines will fail and set
errno
to
ENOENT
for in memory databases.
The
sync
routines may fail and set
errno
for any of the errors specified for the library routine
fsync(2).
BUGS
The typedef
DBT
is a mnemonic for "data base thang", and was used
because no-one could think of a reasonable name that wasn't already used.
The file descriptor interface is a kludge and will be deleted in a
future version of the interface.
None of the access methods provide any form of concurrent access,
locking, or transactions.

Enterprise Search 2014
March 14, 2014 · 2 minute read · CommentsOne of the challenges in a large distributed enterprise is “finding stuff”. Sure we call it collaboration, knowledge management, or any number of other sophisticated terms but often it boils down to just finding stuff.
To compensate the organization reacts by saving multiple copies and versions of a file in many different locations: email, shared file systems, intranets, etc. Of course this compounds the issue and drives the desire to save “my copy” to “somewhere where I can find it”.
A CIO’s role is to figure out how to make this problem go away. So we start with good solid information management concepts:
- We need a taxonomy of our information
- We need to understand our “golden copies”, or master repositories
- We need the information to be very easily searched and discovered by our employees - wherever they are. This problem encompasses:
- Time zones
- Languages
- Geography and the associated latency
- Indexing/crawling many diverse data stores
- It needs to be so simple and easy that it naturally overcomes the employee’s desire save a personal copy.
- We must have mature data access and permissioning processes in place. Unleashing search on corporate systems where permissions aren’t managed well is a huge risk.
But even though these concepts are straightforward they are not easy. Many of us wished we could just “Google” our companies documents. Google understands this and has made enterprise search a product for some time now - it was first released in 2002! I was just taking a look at it recently and it has come a long way from where it started. Relevancy is the key however, and Google considers its relevancy calculation models to be a precious competitive differentiator and therefore keeps them opaque.
Many of us have tried to use Microsoft’s platform in the past but it was always a bit of a challenge to manage, and the results were a hodgepodge. It has also come a very long way with Microsoft’s FAST search technology and in SharePoint 2013 there is a mature approach to deploying search. This clarifies what had long been a confusing product line featuring many different kinds of search capability for SharePoint.
It is encouraging to see the progress and competition in this space. Someday soon corporate document/information search may be as simple as we are accustomed to on the web.

Using JSExplain
Table of Contents
0.0.1 TODO Generic explanatory text here
1 Overview
The JSExplain graphical user interface is presented in Figure 1. It allows the users to load JavaScript programs and execute them in our JavaScript interpreter. The users have at their disposal a mechanism for step-by-step execution with various levels of granularity, exposing all of the underlying details of the execution, as described in the official ECMAScript standard.
Figure 1: JSExplain User Interface
The user interface consists of six components, as shown in Figure 2. These components are:
- Program Selection, where users can choose the program that they wish to execute
- Current Program, where the program that is currently being executed is displayed
- Program Heap State, where the contents of the program heap at the current point in the execution of the program are displayed
- Navigation Panel, which allows the users to step through the program
- Interpreter, displaying the part of the interpreter code that is active at the current point in the execution of the program
- Interpreter State, where the state of the interpreter at the current point in the execution of the program is displayed
Figure 2: JSExplain User Interface Breakdown
2 Program Selection
This component allows the users to select the program that they wish to execute. This can be accomplished in two ways. First, one can click on the list of preset examples, which brings up the selection as shown in Figure 3, and there select the example one wishes to load. Alternatively, one can load a program from a file, by clicking on the "Choose file" button. After either of these procedures, the newly loaded program is displayed in the Current Program component.
Figure 3: Selecting preset examples
3 Current Program
This component serves to display the JavaScript program that we are
executing. The program is shown in its entirety, whereas the part of
the code that is currently being executed is highlighted in
yellow. For instance, in Figure 4, we can see
that the execution of the line x++
is in progress.
4 Program Heap State
This component displays the entire state of the program heap at the
current point in program execution. Illustratively, Figure
4 shows the heap state before the execution of
the command x++
, highlighted in the current program component. This
heap state is collapsed, in that object properties are not shown, but
rather just the objects themselves. At this point, three objects exist
in the heap: the global object, denoted by this, as well as the
lexical and variable environments.
Figure 4: Program heap, collapsed
Objects can be expanded by clicking on the text <Object>
, which is
present to the left of each object's name. This expands the object and
shows all of its properties. For instance, in Figure
5, one can see the expanded global object, with
all of its properties, such as Array
and String
, which are objects
themselves. Also, one can see that the global object has the property
x
, whose value is 1.

- Backward/Forward

6 TODO Interpreter

- JsInterpreter.pseudo
- JsInterpreter.ml
7 Interpreter State
The bottom part of the display is reserved for the component showing the current state of the interpreter, allowing the user an insight that is not commonly available, but which is very important in this setting. Similarly to the program heap, all of the objects and variables are shown, together with the values returned by functions. An example of such a state is shown below in Figure 6.

HAMLET (1996)
A film review by Jun Yan
Copyright 1996 Jun Yan
I think just about everyone knows what the story is, so I won't bother to reiterate it. Here is only my comments on Kenneth Branagh's production. I saw it in 70mm version. It didn't struck me as particularly large, but the color and the texture of the picture is incredibly beautiful, with equally stunning art design, costume and sound effect. The castle was most magnificent both exterior and interior. I cannot give higher praise to the richness of the color. Comparing to the famous version of Lawrence Olivier, this Hamlet is brighter, bolder, and more contemporary, and of course, more violent. I have mixed feelings about including all the sometimes unimportant details of the play into the film, characters who show up for 5 minutes and never seen again, and casting familiar movie stars (mostly American) in minor roles. All the important roles are performed, with good to great effect, by British actors, which makes it serious enough, but the cameos give me a feeling of watching a parody -- not that I dislike it. I think enough people have pointed out the flatness of Jack Lemmon as Marcellus, but Robin Williams gave me the most distraction. He's the material of a lead actor, and his mere presence can make American audience chuckle. He looks very self-conscious at the moment meant to be tragic (when we know that Hamlet doesn't know that he's about to be killed by a poisoned sword). And when he was stabbed to death, it has a rather strange effect. I would rather see this role played by a nameless actor. Other American actors are fairly good in their 10-min to half-hour play. Billy Crystal gave the appropriate touch to the gravedigger, but again I felt like watching a parody of Hamlet. When Billy pullled out a whole row of sculls and bones, I told me friend next to me: "This is not the royal clown's grave, it's John Wayne Gacy's backyard!" Then we both missed the famous speech by Hamlet holding the scull. I mean one scull is enough! The whole film struck me as very uneven and kind of strange as to what KB had been doing. Most parts are made excellently and acted beautifully. KB himself is adequate as the prince. Kate Winslet, IMHO, is better than any other Ophelia I've seen and has a slight edge over other actors in the whole movie. Claudius and Gertude are played well. All the major supporting actors are better than average and are given sufficient time on the screen so that we get to know not only the big players. I especially like the sympathy and explanation given to Ophelia's brother. But there are always sloppy details that bother me. The most laughable is the ghost of old Hamlet. I can't believe how cheesy the special effects are when the ground shakes and steam comes out and thunders roar. We laughed so hard at this point that we missed another speech about how great the old king was and how much he misses him. :) Now I see why Frankenstein was such a flop. KB's special effects are almost as good as Ed Wood's!   I felt a little insulted. The nude scenes of Ophelia and Hamlet having sex have offended many experts, but I thought it was credible in this particular time period in this film. Yet when Gertude describes Ophelia's death, I sat and waited for them to show the touching image of O's drowning and was disappointed with only one shot. I do NOT understand what was going on. It's such an unbalanced production that greatness and silliness co-exist. Did KB hire some really really incompetent filmmaker or was he having short attention span? This Hamlet looks, IMHO, more ruthless and cynical. The film looks quite violent and bloody. My fragile friend had to cover her eye when the camera repeatedly goes back to the pool of blood in the Queen's bedroom.  When the sword flies and nails Claudius, I had a strange feeling that KB would be interested in making something like "Reservoir Dogs." But I liked that scene very much. The death scene of Hamlet was OK, but it does not surpass Mel Gibson's death scene. This film is, as I said, a very unbalanced production. Because of Winslet's great performance (which has not been adequately recognized :P), I give it an A-.

This study is about the first impression of news websites in terms of their graphic design. First, you will be directed to several news websites (but only shown them for 3 seconds) and asked after each news website whether you think that the website looked appealing to you in terms of its layout and colouring (there is no right or wrong, we just want your first impression). After in total eight news websites you are directed back to the survey platform to answer a few more general questions. Then the study is finished and you will be redirected to Prolific.
The answers will be processed anonymously and the whole procedure takes about 10-15 minutes.
After successful completion of the study, we will review your participation and pay you XX$.
If you are interested in being informed about the results of this study, you can contact the researcher Paul Grassl (p.grassl@bsi.ru.nl).
If, for any reason, you do not feel comfortable answering the questions you are free to leave the study at any point, without having to give any reason for it and without any consequence (participation is voluntary). If you have any further questions, you can contact the researcher (through the email address provided above).
Additional notes:
- It is recommended to do the study on a PC/laptop/tablet instead of on a phone.
- Please do not use the back button during the study. If you want to leave the study at any moment, just close the window. Please note that you won't be granted any money without successfully completing the study though.

'Never felt so cheated': NCP's Supriya Sule opens up on rift with cousin Ajit Pawar
Status read, 'Party and family split', and was put up soon after BJP turned tables on rivals with faction of NCP breaking away under Ajit.
by GARGI CHAUDHRYMumbai: Hours after BJP's Devendra Fadnavis took oath as Chief Minister in the early hours of Saturday, with Ajit Pawar as his deputy, Sharad Pawar's daughter Supriya Sule had put up a WhatsApp status that pointed at a major rift within the Pawar family and the NCP.
The status read, “Party and family split”, and was put up soon after the BJP turned tables on rivals with a faction of NCP breaking away under Ajit Pawar — Sule’s cousin and Sharad Pawar's nephew.
In another status that followed soon after, she wrote: “Who do you trust in life...never felt so cheated in my life... defended him, loved him...look what I get in return."
The development brought a major twist in the Maharashtra political scenario as a day earlier it was senior Pawar who had announced that the new Maharashtra government would be led by Shiv Sena chief Uddhav Thackeray.

Now, we want to let the hero fire some bullets to kill the enemies, add the codes below to set the layer touch-enabled.
// cpp with cocos2d-x
this->setIsTouchEnabled(true);
Then we could receive the touch event now. Declare the callback function
void ccTouchesEnded(cocos2d::CCSet* touches, cocos2d::CCEvent* event);
in HelloWorldScene.h, and implement the function in HelloWorldScene.cpp.
// cpp with cocos2d-x
void HelloWorld::ccTouchesEnded(CCSet* touches, CCEvent* event)
{
// Choose one of the touches to work with
CCTouch* touch = (CCTouch*)( touches->anyObject() );
CCPoint location = touch->locationInView(touch->view());
location = CCDirector::sharedDirector()->convertToGL(location);
// Set up initial location of projectile
CCSize winSize = CCDirector::sharedDirector()->getWinSize();
CCSprite *projectile = CCSprite::spriteWithFile("Projectile.png",
CCRectMake(0, 0, 20, 20));
projectile->setPosition( ccp(20, winSize.height/2) );
// Determinie offset of location to projectile
int offX = location.x - projectile->getPosition().x;
int offY = location.y - projectile->getPosition().y;
// Bail out if we are shooting down or backwards
if (offX <= 0) return;
// Ok to add now - we've double checked position
this->addChild(projectile);
// Determine where we wish to shoot the projectile to
int realX = winSize.width
+ (projectile->getContentSize().width/2);
float ratio = (float)offY / (float)offX;
int realY = (realX * ratio) + projectile->getPosition().y;
CCPoint realDest = ccp(realX, realY);
// Determine the length of how far we're shooting
int offRealX = realX - projectile->getPosition().x;
int offRealY = realY - projectile->getPosition().y;
float length = sqrtf((offRealX * offRealX)
+ (offRealY*offRealY));
float velocity = 480/1; // 480pixels/1sec
float realMoveDuration = length/velocity;
// Move projectile to actual endpoint
projectile->runAction( CCSequence::actions(
CCMoveTo::actionWithDuration(realMoveDuration, realDest),
CCCallFuncN::actionWithTarget(this,
callfuncN_selector(HelloWorld::spriteMoveFinished)),

Ok, build and run, touch the screen(on the emulator? click the screen!), and enjoy the effect.


Man Arrested After Jewish Family Racially Abused On London Tube
by Charlie CocksedgeA man has been arrested in Birmingham in connection with a racist incident towards a Jewish family, which took place on the London Underground.
The suspect was reportedly taken into police custody on Saturday, November 23, after a video filmed the day before appeared to show a man reading anti-Jewish Bible verses to a Jewish family – a couple and their three young children – as they travelled on the Northern Line.
The video was filmed by a fellow commuter, who later shared it and appealed to anyone who might recognise the man to come forward.
Footage of the incident reportedly shows the man reading aloud from the Bible towards the family, as the father tries to distract his son.
One passenger tried to defend the family, asking the man to stop the anti-Semitic abuse, before the man threatens to punch him. A few moments later, another commuter tries to intervene, calmly questioning the man and asking him to stop the abusive behaviour.
The commuter, mum-of-two Asma Shuweikh, later told reporters she knew she had to confront the man, and she ‘wouldn’t hesitate to do it again’.
Asma said:
I would have loved more people to come up and say something because if everyone did, I do not think it would have escalated in the way that it did.
Being a mother-of-two, I know what it’s like to be in that situation and I would want someone to help if I was in that situation.
When he started talking to the child I thought, ‘no, I have to say something’. As a mother of two it’s appalling, I can’t sit back and watch that happen.
Asma added:
To be honest I thought it is my duty as a mother, as a practising Muslim, as a citizen of this country, to have to say something.
You can’t just sit back and watch that because I felt that it was just getting out of hand. It was really getting too much.
The footage was recorded by Chris Atkins, who later moved to swap seats with the family so they were further away from the man. Chris told BBC News: ‘It was the children that really got me and everyone else, he was just screaming at these children. It was horrific in every sense.’
Police say they have now arrested a man in Birmingham on suspicion of a racially-aggravated offence.

Light-Dark¶
A simple continuous domain.
Reference: Belief space planning assuming maximum likelihood observations.
Quoting from the original paper on problem description:
In the light-dark domain, a robot must localize its position in the plane before approaching the goal. The robot’s ability to localize itself depends upon the amount of light present at its actual position. Light varies as a quadratic function of the horizontal coordinate. Depending upon the goal position, the initial robot position, and the configuration of the light, the robot may need to move away from its ultimate goal in order to localize itself. Figure 1 illustrates the configuration of the light-dark domain used in our experiments. The goal position is at the origin, marked by an X in the figure. The intensity in the figure illustrates the magnitude of the light over the plane. The robot’s initial position is unknown.
Note that a variant of this domain appears in Online algorithms for POMDPs with continuous state, action, and observation spaces where the state and action spaces are discrete and the observation space is kept continuous. Here we do not implement this variant; You can implement it and create a pull request!
There is an implementation of a variant of LightDarkDomain in the JuliaPOMDP suite (repo).
BLQR planning implementation not complete yet.

| Class | ArkanisDevelopment::SimpleLocalization::LangSectionProxy |
| In: |
lib/lang_section_proxy.rb
|
| Parent: | Object |
This little thing is a big part of the magic of doing things behind Rails back. Basically it mimics an variable (ie. number, array, hash, …) by redirecting all calls to another variable of that kind. The target object will be accessed by the Language#[] accessor and therefore will always return the data for the currently selcted language without replacing the proxy object.
This is useful if Rails stors the target data only in a constant. With this proxy the constant can be replaced once (with a proxy) and will always return the language data of the currently selected language.
Reads the specified options and the accociated block and save them to instance variables.
Available options are:
:sections
Specifies the sections of the language file which contain the receiver. These sections will be used as parameters to the Language#[] method to actually get the receiver.
:orginal_receiver
Specify the original variable that is replaced by this proxy to store this variable inside the proxy. This is useful if you want to combine the language data with the original data. The variable specified here is accessable as the second variable of the attached block.
:lang_class
The class supplying the proxy with language data. Defaults to ArkanisDevelopment::SimpleLocalization::Language. You can for example write a mock class implementing the [] class method use and this option to make the proxy use this mock class. class LangMock def self.[](*sections) {:title => 'test data'} end end LangSectionProxy.new :lang_class => LangMock
If you want to combine the original data (supplied to the :orginal_receiver option) with the localized data in some way (ie. merging the old data with the localized data) you can specify a block. The block takes the localized data as the first parameter, the original data as the second parameter and should return the combined result.
data = {:a => 'first', :b => 'second', :c => 'third'} LangSectionProxy.new :sections => [:letter_to_word, :mapping], :original_data => data do |localized, original| original.merge localized end
# File lib/lang_section_proxy.rb, line 60 60: def initialize(options, &transformation) 61: default_options = {:sections => nil, :orginal_receiver => nil, :lang_class => ArkanisDevelopment::SimpleLocalization::Language} 62: options.reverse_merge! default_options 63: options.assert_valid_keys default_options.keys 64: 65: @sections = options[:sections] 66: @orginal_receiver = options[:orginal_receiver] 67: @lang_class = options[:lang_class] 68: @transformation = transformation 69: end
Gets the receiver from the language class and combines this data with the original data if wanted (a block was specified to the constructor).
# File lib/lang_section_proxy.rb, line 73 73: def receiver 74: receiver = @lang_class[*@sections] 75: if @transformation.respond_to?(:call) 76: receiver = @transformation.arity == 1 ? @transformation.call(receiver) : @transformation.call(receiver, @orginal_receiver) 77: end 78: receiver 79: end


In this document, a 'Query' may refer to a GraphQL query, subscription or mutation.
Query Generator Configuration
The query generator uses the imported schema to generate queries for the target endpoint.
If enabled, it may be configured with the following options.
Maximum Query Depth
The maximum depth of a generated query.
Lenient Maximum Query Depth
If enabled, this option prevents invalid queries by allowing additional depth for fields with no leaf types.
If disabled, Maximum Query Depth is enforced strictly, even if it means generating an invalid query.
Additional Query Depth
The value for this option is used only if the "Lenient Maximum Query Depth" option is enabled.
The maximum additional depth used to search for leaf-type fields.
If a leaf type is not found, the generated query may be invalid and a message is logged.
Maximum Arguments Depth
The maximum depth of specified arguments. This is useful when a field has an input object as an argument.
Specify Optional Arguments
If this option is selected then optional (nullable) arguments will be specified too.
Specify Arguments
Choose how the field arguments should be added in the generated query,
Inline
Using Variables
Both - each query will be sent twice, once with inline arguments and once with variables
Generate Query For
A separate query may be generated for either of the following in the provided schema,
each Leaf, that is, each scalar or enum;
each field under a root operation type (Query, Mutation or Subscription); or
each root operation type.
Request Method
The requests made to the endpoint can be of the following types:
A POST request with a JSON body (Content-Type: application/json)
A POST request with a GraphQL query in the body (Content-Type: application/graphql)
A GET request with the query appended to it in a query string


This page is a demonstration of the elements that can be formatted using Simple.css. Each section includes a code block on how to include it in your site’s design.
This may be a little basic for some people, but I wanted the barrier for entry to be as low as possible for this project.
Basic Typography
All the typography of Simple.css uses
rem
for
sizing. This means that accessibility is maintained for those who change
their browser font size. The
body
element
has a size of
1.15rem
which
makes all the standard font sizes slightly larger. This equates to
18.4px
for
paragraph text, instead of the standard
16px
.
The heading elements also have an increased top margin in order to break blocks of text up better.
Heading 1
Heading 2
Heading 3
Heading 4
Heading 5
Heading 6

This is a H2 header

This is some paragraph text.

Links & Buttons
Links are formatted very simply on Simple.css (shock horror). They use
the accent
CSS
variable and are underlined. There is a
:hover
effect
that removes the underline.
Buttons use the same
accent
CSS
variable for their colour. When hovering, there is an opacity effect.
I'm a hyperlink
<button>I'm a button</button>

<button>I'm a button with a link
</button>
Other typography elements
There are a number of other typography elements that you can use with Simple.css. Some of the common ones are:
- All the standard stuff, like bold, italic and underlined text.
-
Highlighting text using the
mark
element. -
Adding
inline code
using thecode
element. -
Displaying keyboard commands like ALT+F4 using the
kbd
element.
Bold text
Italic text
Underlined text
Highlighted text
Inline code
Alt+F4
Lists
We all love a good list, right? I know my wife does!
- Item 1
- Item 2
- Item 3
- Do this thing
- Do that thing
- Do the other thing
# Bulleted list

Item 1

Item 2

Item 3

# Numbered list

Do this thing

Do that thing

Do the other thing

Blockquotes
Sometimes you may want to quote someone else in your HTML. For this we
use the
blockquote
element. Here’s what a quote looks like with Simple.css:
Friends don’t spy; true friendship is about privacy, too.
– Stephen King

Friends don’t spy; true friendship is about privacy, too.

– Stephen King

Code blocks
Code blocks are different from the inline
code
element.
Code blocks are used when you want to display a block of code, like
this:
body {
color: var(--text);
background: var(--bg);
font-size: 1.15rem;
line-height: 1.5;
margin: 0;
}

body {
color: var(--text);
background: var(--bg);
font-size: 1.15rem;
line-height: 1.5;
margin: 0;
}

Navigation
The nav
menu
is deliberately designed to be extremely simple so that you can improve
on it as you see fit. Or, just leave it as is to have a good looking,
functional navigation menu.
There’s no JavaScript or checkbox CSS hacks here. It’s just a collection of simple “buttons” that wrap to the given width of the page:
The nav
menu
will also adapt to smaller screens automatically so that it doesn’t take
up too much space.
To add a
nav
menu, just
add the following to the

section of your site:

Home
About
Blog
Notes
Guestbook
Contact

Images
In Simple.css, images within the
main
element
are always full width and have rounded edges to them. The
figcaption
element is also formatted in Simple.css.  They’re especially useful when it
comes to things like FAQ pages. Many people invoke JavaScript, or
div
for life
when they use accordions. I don’t really understand why that is when
it’s available in plain old HTML:
Spoiler alert!
You smell. 🙂

Spoiler alert!

You smell. 🙂

Tables
Like lists, sometimes you may need to add a table to your webpage. In Simple.css tables automatically highlight every other row to make reading easier. Table header text is also bold. Here’s what they look like:
| Name | Number |
|---|---|
| Jackie | 012345 |
| Lucy | 112346 |
| David | 493029 |
| Kerry | 395499 |
| Steve | 002458 |

Name
Number

Jackie
012345

Lucy
112346

David
493029

Kerry
395499

Steve
002458

Forms
Forms are useful for all kinds of things on webpages. Contact forms, newsletter sign ups etc. Forms also look pretty good on Simple.css:


- Talks & Tutorial CfP begins: Feb 02
- Tutorial CfP ends: Mar 01
- Talks CfP ends: Mar 01
- Announcement of acceptance: Apr 30
Since one of the PyCon motivation is to help Python eduation and its advocation, by default your talks wil be recorded, edited and uploaded to pyvideo.org by the PyCon Taiwan committe. If you don’t want your talk being recorded, make sure you toggle the recording option off during the proposal submission. See more info about the recording release.
Note that speakers are required to buy the conference ticket as well. (see Everyone Pays Policy).

The Red Badge of Courage
by Stephen Crane
The Red Badge of Courage is an impressionistic novel by Stephen Crane about the meaning of courage, as it is narrated by Henry Fleming, a recruit in the American Civil War. It is one of the most influential American war stories ever written even though the author was born after the war and had never seen battle himself. Crane met and spoke with a number of veterans as a student and he created what is widely regarded as an unusually realistic depiction of a young man in battle.

Key2MyHeart is an installation by Luis Fernandez and Douwe Schmidt where you can use your heartbeat to generate a key to send and receive encrypted mail.
You can contact us by sending an email to<EMAIL_ADDRESS>The Key to my Heart is an interactive ritual where a human can obtain a new and verifiable digital identity in the form of a cryptographic key. A cryptographic key is a number generated in such a way that it can uniquely identify a human. To generate this digital identity we will use something that is unique to you: the beating of your heart.
Good keys are generated from random numbers. Computers are very bad at that so they need external sources of entropy. The heartbeat is a great, and very personal, source of random numbers. So we will help poor little computer by feeding human randomness into it.
Digital identities are very tricky, as the saying goes, on the internet nobody knows you are a dog... or a bot. There's an estimated 3 million bots on twitter interacting with humans and each other. But unlike all these bots, humans have a heart, they don't. To avoid any future misunderstanding as to who is who, we will create a large library of human signatures that are verified as human.
The public part of each key will be uploaded to a keyserver together with a recording of the heart. The private part of the key is given to the human to take home. The human can use this key to send encrypted email and also prove he or she is indeed human in digital contact.

Are you human or d'you make it up?

Are you human or d'you make it up?
(continues...)
Two lovely assistants dressed in white coats will hold a doppler to your heart.  The computer uses the beat of your heart to create your unique key. The speakers are just there for extra dramatic effect.
The key will be placed on a USB bracelet for maximum physical security and for you to take home. On the USB you will also find documentation and software to help you put the key to use. You will also receive a box of matches containing your revocation code as a QR code. You can use the revocation code to make your key invalid in case you loose it. You can use the matches to burn the code in case of an emergency.
A special magnifier attached to the screen allows the individual to confirm we delete any trace of the procedure and keys after he or she received the key to her heart.
This concludes the ritual of the creation of the Key to your Heart
.
With the little ritual of making keys in a very personal setting we want to raise awareness about the difficulties of secure communication. Each step in the procedure is questionable and provocates questions on trust and and pushes boundaries of intimacy. We hope to engage with partakers in a dialogue on privacy online and the challenges it poses.
The slow growth of a library with human generated keys, each one of them verified to belong to a human also raises the issue of singularity and what meassures we need to take to prevent a robot takeover. The wristband and the matches help to make the abstract more tangible and can function as a discussion object at a later date.

Earlier this year, I decided that I should travel more. I have an income now (of sorts), and Uni has given me the confidence to throw some clothes into a bag and scan Easyjet for imminent cheapies. I’ve been to a handful of places this year for longer stints (approx. a week), but I’m talking quick city breaks – where you can pile onto a plane Friday evening and be back Sunday night in time for lectures on Monday morning. University allows that flexibility. I get the feeling that when I start full time employment, I’ll no longer have as much leeway.
First was to go to Amsterdam, this past weekend. Coincidentally, it was also my 21st birthday on the Saturday, so what better way to make something of it!  It sits in the limbo period between people being at home, and people being at University, so it’s hard to get something with large numbers arranged. Me and two others went, it’s an easy number to manage.
The total cost (flights, accommodation and other initial costs) was roughly £180 for 3 nights, Friday to Monday. By the end we’d probably spent around £300 each, not a bad amount.
The first thing I noticed was the support for the English language. A good number of signs and notices were in English, with no Dutch equivalent. Every single person I spoke to spoke English flawlessly, and was happy to talk to you. Ashamedly, I don’t speak a word of Dutch, so this was certainly helpful, but it was just interesting to see the locals speaking English to their own compatriots as well - on the trams, in cafes, on the street. Unlike the French perhaps, who I’ve found can get a little catty when they discover you can’t speak their lingo.
The support for English tended to peak in what could be considered the “tourist” areas. When I went to Rotterdam and Den Haag on the Sunday, everyone still spoke it, but since these cities were more industrial and less commercial it was less relevant in the environment.
Amsterdam has a wide range of attractions, as anyone who has heard of what the city’s famous for will know. Naturally, we walked along the canals during the day, through the Red Light District at night, detected the distinctive smells wafting from the coffeeshops scattered around the city. Around De Wallen (where the RLD is), I expected to feel uneasy. Everything was either rammed into your face with potent neon lighting, or subtly lit with dark red lamps, with every other window containing a girl wearing next to nothing, posing. Sure, you’d get the guys in the long coats going to the windows to enquire about a “purchase”, but there was never any sign of crime, or bad behaviour. None. There were married couples walking around. Elderly folk. It was strange. I feel more uneasy out at night in my home town.
My impression as a tourist who does his own thing (i.e. with no tour guides or whatever) was that in general around Holland, there seems to be a system of tolerance and respect. There is prostitution and mild drug-taking in plain view, but it’s heavily policed, and regulated. Therefore, for those interested, there’s no need to make a crime out of it. When I took trains around the country, my ticket was not checked once, but I was told that the penalty for being caught freeloading would have been severe. I respected that. This just doesn’t happen in the UK. Everything is buried under policy and a lack of common sense, and you’re charged through the ear for it.
The nicest way to get around Amsterdam I found was a water-bike. A pedalo, basically. On the day of my birthday, we were peddling at a leisurely pace around the canals with full sun in the sky. It was lovely, and I got some great snaps out of it. It cost us 10 euros each for an hour and a half – well worth it. You can find them along the west side of the Central quarter, from outside the Rijksmuseum upwards.
Bicycles were everywhere. At all times of the day. Everywhere had a bike lane, and you better believe that they get right of way! It took some getting used to, having to look both ways for bikes, then stepping forward to do the same for cars. I got an angry bell my way several times.
To be honest, I didn’t have the time to go and visit the city’s many museums. On city breaks I prefer to walk around and see things – it’s also the cheaper option. And that certainly applied here – Amsterdam is an expensive place! One place, it was 6 euros for a beer. £4.80. And not even a pint. It’s in a pint glass, but you get 3/4 drink and 1/4 froth. Needless to say, the lads soon regretted their offer to buy the rounds on my birthday night. Other examples included 4 euros for a waffle and 3 for a cone of chips!
It’s expected though, as Amsterdam is both lovely and the country’s capital. It’s a tourist trap as well as a hub. As I mentioned previously, Rotterdam and Den Haag had less to see. Rotterdam has the world’s 3rd largest port and great modern architecture (because it was levelled in the war), and Den Haag has the parliament and royal buildings (and the International Court), but not a great deal else. I’m probably wrong, of course, but that was my first impression. As for Amsterdam, I felt like I only scratched the surface of it over the 3/4 days I was there. I would certainly go back.

The Gift (2000) 2 stars out of 4. Starring Cate Blanchett, Keanu Reeves, Giovanni Ribisi, Greg Kinnear, Katie Holmes, Hilary Swank, Gary Cole and J.K. Simmons. Screenplay by Billy Bob Thornton and Tom Epperson. Directed by Sam Raimi. Rated R.
With the exception of the performance of Cate Blanchett, The Gift is a major disappointment.
Written by actor-director Billy Bob Thornton and Tom Epperson, and directed by Sam Raimi, the movie crawls, the plot is flimsy and the suspense is minimal.
This is one of those Southern Gothic tales filled with eccentric and offbeat characters who seem to only exist below the Mason-Dixon line.
Supposedly Thornton based Blanchettís Annie Wilson, who is psychic, on his own mother who read fortunes.
Annie, a young widow with three boys, uses her gift to do readings for the locals in her rural Georgia town. At times, she has visions in which she sees future events as well as some that already have passed.
This gets her involved in the murder of Jessica King (Dawson Creekís Katie Holmes), a young, rich, spoiled local woman who is found strangled in a pond, a chain wrapped around her body.
Of course, the main suspect, Donnie Barksdale (Keanu Reeves) is a redneck, cheatiní, wife beater who has threatened Annie because she does readings for his abused spouse (Oscar-winner Hilary Swank), urging the poor woman to leave Donnie.
Now, since The Gift is part murder mystery, anyone with any film sense knows immediately Reeves is not the killer.
And so because the filmís main characters are sparse, the list of suspects is greatly narrowed, making the identity of the killer easy to determine. Is it Wayne Collins (Greg Kinnear), her school principal fiancé? Or is it David Duncan (Gary Cole), the county prosecutor with whom Jessica was having an affair? Or could it be Buddy Cole (Giovanni Ribisi), the local nut case who was sexually abused as a child by his father? Or maybe it was Valerie Barksdale (Swank), who knew her hubby was carryiní on with Jessica.
The Gift would have been a better movie if it had concentrated more on Annie Wilson and her interaction with the other townspeople ó some of whom think sheís a witch ó than forcing its audience to walk through this transparent labyrinth trying to guess who the killer really is.
For Blanchettís Annie is very reluctant about using her power, which it seems she considers more of a burden than a gift. Instead of telling people their futures, she tries to set them on the right path to determine their own destinies.
The Gift is partly redeemed by its Twilight Zone-like resolution, but overall it remains an unsatisfying endeavor.
Blanchettís Annie is an interesting individual. At times she is frightened by her gift, tentative about how to use it. Up front she tells her clients that she cannot solve their problems, only suggest the road they must take to reach their own resolution.
At times, though, the script undermines her. When she realizes Donnie, who has been convicted of Jessicaís death, is not guilty, she runs to the prosecutor, spills the beans about seeing him and Jessica catching a quickie in a closet, and insists he reopen the case.
She also visits Wayne, telling him of her feelings that Donnie has been railroaded. Not a smart thing to do since these two guys would now be considered suspects.
The performances in The Gift, other than Blanchettís, are rather uneven. Reeves plays Donnie as if auditioning for one of the deranged backwoodsmen from Deliverance; Ribisi gives another of his, ìHey look at me, I'm nutsî characterization for which he seems to be becoming typecast; Swank is totally wasted; while Kinnear plays Wayne as a rather passive, colorless lacking any real personality.
Only J.K. Simmons (best known as the racist inmate on HBOís Oz) is memorable as the easy-going county sheriff who is dubious of Annieís gift.
The scene in which he asks about a missing eclair while she is trying to give him information about the missing Jessica is priceless. If only more sequences in The Gift could have been so well written.
The Gift is a flawed movie that wastes the potential of its cast. It falls short as a character study, a thriller and a mystery.

I have several projects on the go all at different stages and I have then on different hdd partitions and regularly swap between them or reinstall for one reason or another. What I would like to do is reuse an EmonCMS API key across multiple installs, only one will ever be live at any given time.
Currently every time I do a fresh install or switch from one image to another I have to edit the oem_gateway.conf file on my forwarding pi. not a difficult job but if I could reuse the same key it would be great to not have to keep changing it.
Also are ALL emonCMS data files in one location, is there one location that if I mount a "data" partition to I can use the same database across several images?
Can local EmonCMS v8 API key be edited ?

Quick Start¶
A sample data field is provided in the samples directory. Following examples are using that file.
Plotting smoother degree distribution¶
>>> from DoaProcessor import DoaProcessor
>>> d = DoaProcessor('./samples/sample.csv',4)
>>> # You can tweak value of sigma to change the smoothness
>>> d.getPeakDegree(sigma=2,group='group-1')
Degree distribution plot will help you in understanding the directions for each speaker. For instance, the above figure shows that highly captured directions are around 0, 100, 180,300 degrees.
Extracting speaking time for each speaker¶
In order to extract the speaking time, you need to specify the corresponding degrees for each speaker. This knowledge can be gained from the sitting arrangement of speakers around microphone arrays. You can also learn about it by manually exploring the degree distribution.
>>> from DoaProcessor import DoaProcessor
>>> d = DoaProcessor('./samples/sample.csv',4)
>>> # manually setting directions for each user
>>> d.setDegreeForSpeaker(group='group-',[30,104,194,315])
>>> d.getSpeakingTime(plot=True,time='sec',group='group-1')
Generating social network¶
>>> from DoaProcessor import DoaProcessor
>>> d = DoaProcessor('./samples/sample.csv',4)
>>> # manually setting directions for each user
>>> d.setDegreeForSpeaker(group='group-',[30,104,194,315])
>>> d.drawNetowrk(group='group-1')

The most basic analogy that I can think of is thinking html as a structure of a house so basically html is used to build a house (website) and then css would be interiors and exteriors of the house so css makes html look pretty,modern,fancy etc depending on how you use it. Dom is almost like a house plan you can see how the house is built and you can modify delete move around the structure of the house without actually touching the actual structure of the house (html)
All of the elements on website is made out of box. Complicated looking websites are also made out of box as well but you need more boxes than the other simple website to create it Boxifying design means looking at websites and thinking it as a grid to place logos, images, text and many others.
Box model is basically boxes around the object such as texts and images. We call this margin, border and padding. This box allows people to give space around this objects and you can adjust size of the box as well. This box is not viewable on website but only on html. Think of this box model as a clear bubble around images and texts that keeps things away from other objects.

How to cite these notes, use annotations, and give feedback.
Note: These are working notes used for a course being taught at MIT. They will be updated throughout the Fall 2023 semester.
| Previous Chapter | Table of contents | Next Chapter |
These days, there is a lot of excitement around reinforcement learning
(RL), and a lot of literature available. The scope of what one might
consider to be a reinforcement learning algorithm has also broaden
significantly. The classic (and now updated) and still best introduction to
RL is the book by Sutton and Barto
My goal for this chapter is to provide enough of the fundamentals to get us all on the same page, but to focus primarily on the RL ideas (and examples) that are particularly relevant for manipulation. And manipulation is a great playground for RL, due to the need for rich perception, for operating in diverse environments, and potentially with rich contact mechanics. Many of the core applied research results have been motivated by and demonstrated on manipulation examples!
There are now a huge variety of RL toolboxes available online, with widely varying levels of quality and sophistication. But there is one standard that has clearly won out as the default interface with which one should wrap up their simulator in order to connect to a variety of RL algorithms: the Gym.
It's worth taking a minute to appreciate the difference in the OpenAI
Gym Environments
(gym.Env
) interface and the Drake System interface; I think it
is very telling. My goal (in Drake), is to present you with a rich and
beautiful interface to express and optimize dynamical systems, to expose
and exploit all possible structure in the governing equations. The goal in
Gym is to expose the absolute minimal details, so that it's possible to
easily wrap every possible system under the same common interface (it doesn't matter if it's a robot, an Atari game, or
even a compiler). Almost
by definition, you can wrap any Drake system as a Gym Environment.
An OpenAI Gym Environment is an incredibly simple wrapper around
simulators which offers a very
basic interface, most notably consisting of reset()
,
step()
, render()
. The
step()
method returns the current observations and the
one-step reward (as well as some additional termination conditions).
You can wrap any Drake simulation in an OpenAI gym environment, using
from manipulation.drake_gym import DrakeGymEnv
The DrakeGym
constructor takes a Simulator
as well as an input port
to associate with the actions, an output port to associate with the
observations, etc. For the reward, you can implement it as a simple function of the Simulator
Context
, or as another output port.
DrakeGym
is built around a Simulator
(not just a System
) or a function that produces a random
Simulator
because you might want to control the integrator
parameters or have each rollout contain the same robot in a different
environment, with potentially different numbers of objects. This would
mean that the underlying System
might have a different
number of states / ports. The notion of a function that can produce
simulators, referred to as a SimulatorFactory
, is core to
the stochastic
system modeling framework in Drake.
You can also use any Gym environment in the Drake ecosystem; you just won't be able to apply some of the more advanced algorithms that Drake provides. Of course, I think that you should use Drake for your work in RL, too (many people do), because it provides a the rich library of dynamical systems that are rigorously authored and tested, including a great physics engine for dealing with contact, and leaves open the option to put RL approaches head-to-head against more model-based alternatives. I admit I might be a little biased. At any rate, that's the approach we will take in these notes.
Some people might argue that the more thoughtfully you model your system, the more assumptions you have baked in, making yourself susceptible to "sim2real" gaps; but I think that's simply not the case. Thoughtful modeling includes making uncertainty models that can account for as narrow or broad of a class of systems as we aim to explore; good things happen when we can make the uncertainty models themselves structured. I think one of the most fundamental challenges waiting for us at the intersection of reinforcement learning and control is a deeper understanding of the class of models that is rich enough to describe the diversity and richness of problems we are exploring in manipulation (e.g. with RGB cameras as inputs) while providing somewhat more structure that we can exploit with stronger algorithms. Importantly, these models should continually expand and improve with data.
The OpenAI Gym provides an interface for RL environments, but doesn't provide the implementation of the actual RL algorithms. There are a large number of popular repositories for the algorithms, too. As of this writing, I would recommend Stable Baselines 3: it provides a very nice and thoughfully-documented set of implementations in PyTorch.
One other class of algorithms that is very relevant to RL but not specifically designed for RL is algorithms for black-box optimization. I quite like Nevergrad, and will also use that here.

You can find more details on the derivation and some basic analysis of these algorithms here.
rl/box_flipup.ipynb

This is a great time for theoretical RL + controls, with experts from controls embracing new techniques and insights from machine learning, and vice versa. As a simple example, we've increasingly come to understand that, even though the cost landscape for many classical control problems (like the linear quadratic regulator) is not convex in the typical policy parameters, we now understand that gradient descent still works for these problems (there are no local minima), and the class of problems/parameterizations for which we can make statements like this is growing rapidly.
For this exercise, you will implement a stochastic optimization scheme that does not require exact analytical gradients. You will work exclusively in . You will be asked to complete the following steps:
For this exercise, you will implement the vanilla REINFORCE algorithm on a box pushing task. You will work exclusively in . You will be asked to complete the following steps:

Development¶
Unit tests¶
Each file in rtd_lib
has a corresponding test file with prefix test_
placed in rtd_lib_test
folder.
To run all tests and asses code coverage (the share of code tested) using the coverage
package, run the following
command in terminal:
coverage run --source=./bio_rtd -m unittest discover bio_rtd_test; coverage report
To see the detailed coverage analysis (e.g. to discover non-covered lines), run:
coverage html
and open htmlcov/index.html
in web browser.
Running tests without code coverage:
python -m unittest discover bio_rtd_test
If you create a pull request, please add appropriate tests, make sure all tests succeed and keep complete (100 %) code coverage. If needed, also update the documentation.
Documentation¶
Dependencies (pip
packages):
sphinx
sphinx_autodoc_typehints
sphinx_rtd_theme

Thanks for submitting the idea, Bastian.
Although I think the Growl thing would work, it is pretty limited because most of the notification styles that Growl provides limit that amount of text that can be displayed to much less than the length of a set of lyrics for a song (the rest of the output is truncated).
So although it could be down with Growl, I think to be done well Synergy would need to provide a window/bezel of its own showing the lyrics which would handle the quantities of text required.
Marking as ASSIGNED.

Adding "REQUEST:" to the summary.

That amount of lines of text is a option in the growl pref. pane (in the visualisation options), and can be turned on or off, to display more than 5 lines in a notification (i think is off by default).
Adding that to the Synergy bezels would be great, but i still thinking in growl notifications, because in old computers (i have a g3) the bezels works a bit slow... but i will be happy anyways :P

I changed my mind, its a better idea to add the lyrics in a Synergy notification, because of you can create (i think) buttons to the bezel (like a rezise button, a close button, etc), and i tested again the Synergy bezels (without having Windowserver overloaded xD) and they worked cool.
