THE ASTRONAUT'S WIFE (New Line) Starring: Johnny Depp, Charlize Theron, Joe Morton, Clea DuVall. Screenplay: Rand Ravich. Producer: Andrew Lazar. Director: Rand Ravich. MPAA Rating: R (sexual situations, profanity, violence, adult themes) Running Time: 106 minutes. Reviewed by Scott Renshaw.
In this summer of uniquely adult suspense fare like THE BLAIR WITCH PROJECT and THE SIXTH SENSE, THE ASTRONAUT'S WIFE initially seems like a promising companion piece. Writer/director Rand Ravich's tale begins with blissfully happy couple Spencer Armacost (Johnny Depp) and his wife Jillian (Charlize Theron) sharing a tender moment before Spencer's latest mission as a shuttle astronaut. That mission goes awry, however, sending Spencer and a fellow astronaut home unconscious after an unexplained communications failure during a spacewalk. Both men initially seem to come through the experience fine, but Jillian slowly begins to sense something amiss with Spencer after they move to New York City. She's even more troubled once she becomes pregnant with twins, and a former colleague of Spencer's (Joe Morton) shows up with some disturbing information.
There's certainly an aura of familiarity to the story, but that almost seems to work for the build-up of suspense. Charlize Theron's Mia Farrow-circa-ROSEMARY'S BABY hairstyle hardly seems coincidental, much like the mere casting of Theron after THE DEVIL'S ADVOCATE (Theron characters clearly need to stop moving to New York, encountering sinister forces and going insane). Everything about THE ASTRONAUT'S WIFE aims for an ever-growing sense of menace -- Ravich's odd camera angles, time-lapses and slow motions; cinematographer Allen Daviau's murky photography; production designer Jan Roelfs' sterile interiors. Technically, there's a lot to like about THE ASTRONAUT'S WIFE and the way it keeps a viewer unsteady and uneasy.
As a narrative however, nearly everything seems just ever-so-slightly off. The film feels like it starts too late, eventually revealing crucial pieces of Armacost family history that really should have been shown to us. Individual scenes flow smoothly, but the transitions between them are awkward and abrupt. Characters who seem like they should play a much more significant role flit in and out of the story inconsistently. Ravich doesn't seem entirely in control of the pace, letting the film ooze along eerily without ever knowing where to crank it up or tone it down. The familiar "devil inside" plot elements are played deadly straight, creating the impression that Ravich is taking his story far too seriously. Even the key moments of exposition drift by so deliberately they're gone before you have a chance to register that they might be important. THE ASTRONAUT'S WIFE spends 106 minutes convincing you that it's just about to turn into something compelling, then never does.
The performances and characters are certainly a significant part of the problem. Like the rest of the story, the characters feel incomplete. Depp plays the post-close encounter Spencer with a disquieting flatness, but we see too little of Spencer the good guy to make the transition unsettling. Theron has already proven in THE DEVIL'S ADVOCATE that she knows how to play frantic and tormented, but again there's a back-story missing from her performance (though it's dropped into the dialogue). Even the usually reliable Joe Morton is left adrift when his NASA operative turns up as an unshaven wacko with no sense of how he became one. Ravich keeps building THE ASTRONAUT'S WIFE as though the plight of the characters is going to elevate the genre story, when ultimately the characters don't mean a thing.
I must admit that I was startled to find THE ASTRONAUT'S WIFE remotely watchable when it appeared without preview screenings. The look of the film is nearly enough, combined with Theron's haunted stares, to make it linger in your head for a while. It just doesn't deliver on the most basic level, leaving you itchy and unsatisfied as though you had just watched a film that wasn't quite finished yet.  After you get through admiring the style of THE ASTRONAUT'S WIFE, all you're left with is a lot of empty space.
On the Renshaw scale of 0 to 10 alien damnations: 5.

Posting JSON data to the Django REST Framework with AJAX
This article will explore the challenges I faced recently while trying to make POST requests with JSON data to the Django REST Framework using jQuery’s AJAX function. After tracing down all of the error messages into the documentation for Django, Django REST Framework, jQuery and JavaScript and many Stack Overflow questions, I was finally able to see my “It worked!” alert pop up from the success
callback.
Context
This issue came up over the weekend while working on a JavaScript game I started several months ago. The game is a ‘dungeon crawler’ where the characters and environment are represented by Unicode emoji. In the initial version, you control a character who roams through a forest, slays a dragon that threatens a princess in distress, and then meet the King of the Land, hence the name of the game “King’s Encounter”. I wanted an easier way to design levels, and also wanted to let users create and share their own worlds and adventures.
The entire game state is stored in a JavaScript object. Here’s a simplified representation of the structure:
var game = {
"map":{
"0":[tree, tree, tree,],
"1":[tree, player, tree,],
"2":[tree, tree, tree,],
}
}
The UI lets users manipulate the values of each row in the game state’s map
property. The values of the row arrays are objects themselves, which contain information about which emoji they represent and how they interact with the player (for example, you can’t pass through a tree, so it has a 'wall':true
property).
I added a “Save Game” button, which when clicked would fire a POST or PUT request to create or update the user’s game design. On the homepage of my personal website I includes a simple AJAX POST, so I first copied it over as boilerplate code to modify.
$("#post-form").on('submit', function(event){
event.preventDefault();
var this_ = $(this)
var gb_endpoint = this_.attr("data-href")
$.ajax({
url: gb_endpoint,
type: "POST",
data: { message : $("#post-text").val(),
csrfmiddlewaretoken: '{{ csrf_token }}',
city: "some city",
state: "some state",
},
success: function(json){
$('#post-text').val('');
$('#post-form').blur();
var gb_num = $("#gb-num").text();
var new_gb_num = parseInt(gb_num) + 1
$("#gb-num").text(new_gb_num);
if (1 == 1){
var user = json.user
$('#guest-book-items').prepend('

From {% if user.is_authenticated %}{{ user }}{% else %}someone{% endif %} in the ' + json.city + ', ' + json.state + ' area | just now

' + json.message + '

')
}
},
});
Here’s the AJAX call that worked after lots of debugging:
$("#save-level").click(function(event){
event.preventDefault();
$.ajax({
type : "POST",
url : "/api/kings/save/",
csrfmiddlewaretoken: "{{ csrf_token }}",
data : JSON.stringify({game:scene}),
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
success: function(){
alert("Saved! It worked.");
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("some error " + String(errorThrown) + String(textStatus) + String(XMLHttpRequest.responseText));
}
});
});
Django REST Framework settings and API endpoints
Before I started writing the AJAX call, I looked in the Django REST Framework documentation for instructions on how to post JSON data. Here are the REST Framework settings I added to settings.py
:
REST_FRAMEWORK = {
'DEFAULT_RENDERER_CLASSES': (
'rest_framework.renderers.JSONRenderer',
),
'DEFAULT_PARSER_CLASSES': (
'rest_framework.parsers.JSONParser',
)
}
I’m not sure if this was completely necessary, but I think the JSONRenderer
helps with the serialization of Unicode data, since earlier attempts returned Unicode representation of emoji rather than the emoji themselves (e.g., U+1F600 instead of 😀).
I should also mention that I added a simple “Game” model in models.py
:
from django.contrib.postgres.fields import JSONField
class Game(models.Model):
game = JSONField()
Next I added the views and serializers for the API endpoint (/api/kings/save/
) for the POST request:
kings/api/views.py
from ..models import Game
from .serializers import GameSerializer
from rest_framework.generics import CreateAPIView, # ListAPIView
from rest_framework.views import APIView
from rest_framework.response import Response
class GameCreateAPIView(CreateAPIView):
queryset = Game.objects.all()
serializer_class = GameSerializer
def perform_create(self, serializer):
game = self.request.data
_ = serializer.save(game=game)
return Response(_)
# class GameListAPIView(ListAPIView):
# queryset = Game.objects.all()
# serializer_class = GameSerializer
kings/api/serializers.py
from rest_framework.serializers import ModelSerializer
from rest_framework import serializers
from ..models import Game
class GameSerializer(ModelSerializer):
class Meta:
model = Game
fields = [
'game'
]
Writing this view was the first big hurdle. I was under the impression that the JSON data was to be accessed in self.request.body
. The error message said You cannot access body after reading from request’s data stream, and there were some elaborate solutions that I didn’t think I would be able to implement.
This topic in the DRF documentation describes the .data
method for parsing requests.
Debugging the AJAX call and formatting JSON data
The next important clue came from a footnote in this section about requests:
Note: If a client sends malformed content, then accessing request.data may raise a ParseError. By default REST framework’s APIView class or @api_view decorator will catch the error and return a 400 Bad Request response. If a client sends a request with a content-type that cannot be parsed then a UnsupportedMediaType exception will be raised, which by default will be caught and return a 415 Unsupported Media Type response.
I resolved the 415
error by adding the following to the AJAX call.
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
One aspect of all of the debugging which was frustrating is that the sqlite3 database on my local environment does not support storing JSON data (as far as I know), so I committed and pushed code to my production server on Heroku (which uses PostgreSQL) for each step in the debug process. Eventually I realized that a 500
server error on my local environment meant that everything was working correctly except for the very last step: saving the Game
object.
At this point I thought I was pretty close. I could successfully POST data using the DRF web interface, and I got the following type of error messages (which were HTTP 400 Bad Request
) when I tried to post malformed data:
{
"detail": "JSON parse error - Expecting value: line 2 column 13 (char 14)"
}
To see what error message I was getting using AJAX, I found that jQuery makes the error message available in XMLHttpRequest.responseText
. I then added the following to the AJAX error
callback:
$.ajax({
...
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("some error " + String(errorThrown) + String(textStatus) + String(XMLHttpRequest.responseText));
}
});
This error message was saying:
ValueError: Expecting value: line 1 column 1 (char 0)
This led me to believe that there was an issue with the data
attribute being passed into the AJAX call. It was particularly difficult to figure out how to write the JSONified version of JavaScript object. SO posts had many different ways, and I eventually found that the following worked:
$.ajax({
...
data : JSON.stringify({game:scene}),
Since I named the JSONField()
field in my Game model game
, I believe that game
needed to be the “main attribute” of the JSON in the POST request. scene
is the name of the variable that held the JavaScript object I wanted to send. JSON.stringify()
was a little confusing, and there was lots of confusion online about what it returns. Here’s the MDN documentation that was helpful in figuring out JSON.stringify()
.
Cross-site Request Forgery issue when using AJAX with Django
At some point in all of this debugging I got a strange error message saying the CSRF Token was missing or incorrect. I had included csrfmiddlewaretoken: "{{ csrf_token }}",
in the AJAX call, and it wasn’t an issue I had experienced with making my other POST request with AJAX. I found this Stack Overflow answer with 143 votes and 90,322 views, and was pleased that the proposed solution worked just fine. It involves adding $.ajaxSetup()
before the AJAX call:
$.ajaxSetup({
beforeSend: function(xhr, settings) {
function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
// Only send the token to relative URLs i.e. locally.
xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
}
}
});
I won’t go into to much detail here, but you can read more about this issue which apparently also impacts Ruby on Rails as well. Here’s a link to a security post on the Django Project blog.
Finally, I pressing the Save Game
button gave me the long-awaited succss message: Saved! It worked.
Conclusion
I still have quite a bit of work to do before the “level-building” feature is complete for this game. Hopefully there are not as many issues in retrieving JSON data stored in the database.
It would probably make more sense to build this type of game with a JS backend and a NoSQL database, but it is good to know that Django + DRF + PostgreSQL can handle this.
A live demo of the level-building is available here: http://briancaffey.com/kings/kingsencounter/level_builder, and you can find a demo of the game here: http://briancaffey.com/kings/kingsencounter/. Here’s what the game looks like:
If you save your game, you can see the JSON in the list of all saved games using the DRF web UI: http://briancaffey.com/api/kings/games/. One of the very next things I need to do on the backend assign a unique URL to each Game
object and update that Game
model rather than creating new games with each request. This will involve something like UpdateAPIView
in the REST Framework.
Hopefully this article is helpful if you are struggling with making an AJAX POST request to DRF on the backend. Thanks for reading and feel free to leave a comment if you have any thoughts or questions or can point out something I can improve.


Re: Modular Park Sets by mdk_813 [park] UPDATE
So guys,
I've got a BIG one for you today:
The Modular Park Set by mdk_813
This set is so extensive, I decided to split it up into five parts. You can download all of them or you can select the parts that you want and leave out those which you do not need or want.
In total the sets contain 94 individual pieces that are grouped in 27 entries in the park menu. This might seem a bit overwhelming but I tried to group them logically, so don't worry.
----
Before we look closer at the different sets, here is some possibly useful advice about placing puzzle tiles, as I understand that this can get tedious:
It is usually a good idea to determine the rough shape of what you want to build by placing the corner pieces first. This helps in deciding which pieces need to be put in which spot. Then you continue with intersections and if provided endpieces. Finally, you place the straights. Following these steps could probably spare you from having to switch back and fourth between different pieces all the time
----
So, here is a rundown of what the sets contain:
- Modular Park pt.1 (Trees):
This Set can be considered the basic Starter Set. It contains simple 1x1-park lots. a lot with grass, some different trees and palms and a flowerbed.
The trees were originally made by Lobby and Theo, I simply adjusted the tree foundation in some of the lots. The grass, the palms and the flowerbed are mine. Actually, the palms can be also found in my palms and bushes plugin for the terrain menu which you can find here: viewtopic.php?f=58&t=3739
The concrete texture is modeled to align with Lobby's and Theo's concrete-park tiles, but it is infact a different texture generated by me. The palms come both on the grass texture and on the concrete texture. The latter allow you to use them between the lanes of avenues for example.

- Modular Park pt.2 (Parkway):
This Set contains a number o1x1-tiles that allow you to create parkways and squares. It uses the same concrete texture which blends in with the one by Lobby and Theo.
The slim parkway iincludes straights, straights with bench and lamp. corners, crossings and T-intersections.
The wider Square-pieces include Straights, straights with bench and lamp, outside and inside corners, T-Intersections and semi-T-Intersections (which open up to the left or the right respectively). All of these square-pieces allow you to place original park-tiles from the game next to them in order to create, as the name suggests, larger squares.

Legacy C in modern C++
[tl;dr] The integration of C
in C++
was designed a long time ago and the mechanisms are efficient but spartan, forcing the client code to take care to manage memory and data access. When integrating into modern C++
, where there is often a culture of good memory management and pointer manipulation, these mechanisms are not comfortable. There are solutions to interface C
code more cleanly, through OOP or or C++
smart pointers.

Table of Contents
Motivations
It has been a long time since the last time I wrote an article. Not for lack of an idea, I thought of this one shortly after the first article. But writing the first article took me a lot of time and energy, and basically it was too long to be useful. I think my PhD student background played a key factor at the time. I had an idea, a willingness to share something, and I reapplied the same rigid structure that I used in my scientific articles, which is clearly not science here. This blog should rather be used to say what goes through my head, even if it’s not as rigorous as my scientific work.
As of now, I have been a PhD for almost a year. I left a multinational company to join another one, and it works for me for now. I am working more on execution than simulation at the moment, but I have inherited a certain background in simulation that I would like to share.
Context
In the simulation business, reusability and compatibility are very important. A simulation model can have a very long lifetime, and today with MBSE approaches, a simulation model can exceed the lifetime of the component it simulates.
In this context, it is reasonable to be willing to create models that are as accessible as possible outside of the environment in which they were created, and as far as I am aware, the worst thing that can happen to a simulation model that is intended to be reused is to be developed in an exotic, or worse, specific language.
Introduction
In my PhD thesis, I had abstracted the problem by treating the model interface as a signature, implementable, and I think this compromise is a good way forward. Here is the compromise I propose: Implementing simulation models in a stable, portable language that can be trusted to be reused as is for decades to come, without modifying a single line of code, and in parallel, improving the simulator to take advantage of technical improvements. From my point of view, and if there is a guarantee that the simulation scheduling is mastered, which is what I propose in my thesis, then the best of both worlds will be made use of.
On the one hand there is a set of models on which it is possible to capitalize and keep an archive for analysis, and on the other hand the performance of the simulation is constantly improving.
From my point of view, there is only one language that offers confidence in reusability and compatibility, and that is C
, ANSI standard.
No matter what architecture is used, no matter what kind of embedded system, no matter how old it is, there is always a way to compile and run C89.
So the question is, why not develop everything in C89
since it’s so good?
This is a good question, unfortunately the C89
suffers from shortcomings when it comes to quickly implementing a complex architecture…
Specifically C89
does not offer the possibility to easily implement object-oriented or functional paradigms, and these are the paradigms that designers use, and they are right to do so.
I’m the first one to criticize the object-oriented, I think this paradigm is too far from reality, but I must admit that when I design a solution, I rely on it a lot, and it simplifies my job.
C++
is just one of those languages that implement the object-oriented paradigm, that’s the main difference with C
, and that’s where there is a huge divergence with C
.
Beyond the technical question of integration, how to integrate elements designed in one language with its paradigms in another language, with its own paradigms.
Discussions
When I took up the ROSACE
case study for my thesis, a lot of implementation work had already been done on it, including in C
.
I wanted to quickly reuse these C
elements, but in a much more modern solution.
I hesitated between C++
and python
, and in the end, it was C++
which answered best to the other needs of my thesis.
Integrating C in C++
Integrating C
code into C++
is technically incredibly simple, one just have to use:
extern "C"
Thus, for a function declaration in a C
header as following:
int old_func(int x);
This function can be used in C++
code as in C
code:
const auto X = old_func(42);
As long as the header is included such as in the following:
extern "C" {
#include <header.h>
}
Or if the header includes the following code:
#ifdef __cplusplus
extern "C" {
#endif
/* ...declarations ... */
#ifdef __cplusplus
}
#endif
Which is not always the case with legacy code.
But the question of reuse strategy comes up very quickly.
Two solutions emerge: either to take over the paradigms of the old language or to implement those of the new one.
Here in the integration of C89
in C++
(11 at the time of my thesis, but I will use C++20 in this article), it is either a question of choosing the procedural approach and reusing functions in the same way as one would do in C
, or using classes to encapsulate.
Thus, a declared C
structure:
struct old_struct {
int x;
};
typedef struct old_struct old_struct_t;
Can be manipulated in C++
as a native C++ struct
, i.e. with default constructor and all public members.
auto os = old_struct();
os.x = 42;
const auto X = os.x;
However, the use of C-structures is not just for packaging data, and there are sometimes associated functions that process these structures. Here let’s simply consider a getter and a setter on the x property:
void old_struct_set_x(old_struct_t *p_old_struct, int x);
int old_struct_get_x(const old_struct_t *p_old_struct);
The passage by reference does not exist in C
, it will be necessary to switch back to a way of calling the functions on these not so modern structures, directly inherited from C:
auto os = old_struct();
old_struct_set_x(&os, 42);
const auto X = old_struct_get_x(&os);
More complicated, if the legacy code contains private implementations, such as:
struct old_pimpl;
typedef struct old_pimpl old_pimpl_t;
In C++
, it will be necessary to manipulate all the allocation, initialization, destruction and manipulation functions as in C
.
Here let’s consider these functions:
Allocation and initialization:
old_pimpl_t *old_pimpl_new();
Finalization and destruction:
void old_pimpl_del(old_pimpl_t *p_old_pimpl);
Data manipulation:
void old_pimpl_set_x(old_pimpl_t *p_old_pimpl, int x);
int old_pimpl_get_x(const old_pimpl_t *p_old_pimpl);
The usage of the old private implementation is heavy:
auto p_op = old_pimpl_new();
old_pimpl_set_x(p_op, 42);
const auto X = old_pimpl_get_x(p_op);
old_pimpl_del(p_op);
Wrapped integration
The obvious solution to avoid inheriting the cumbersome use of C
is to adapt the old structures and interface with a single class.
For our old_struct
, the OldStructWrapper
class can be declared.
class OldStructWrapper final {
// ...
};
Aggregation with a public structure consists of a simple private declaration:
class OldStructWrapper final {
// ...
private:
old_struct os;
// ...
};
Data manipulation can be hidden behind methods to get the most out of C++
.
The client of the OldStructWrapper
class will not have to explicitly manipulate pointers and references:
class OldStructWrapper final {
// ...
public:
// ...
void set_x(int x) {
old_struct_set_x(&os, x);
}
// ...
};
The compiler may receive more complete information, such as the prohibition of not retrieving the result, or the purity of the method:
class OldStructWrapper final {
// ...
public:
// ...
[[nodiscard]] auto get_x() const -> int {
return old_struct_get_x(&os);
}
// ...
};
The OldStructWrapper
class can therefore be completely explicitly implemented:
/// Old struct wrapper
class OldStructWrapper final {
private:
old_struct os; ///< Old struct composition
public:
/// Old struct constructor
OldStructWrapper() = default;
/// Old struct destructor
~OldStructWrapper() = default;
/// Old struct copy constructor
OldStructWrapper(const OldStructWrapper &) = default;
/// Old struct copy assignment
/// \return Copy of other old struct wrapper
OldStructWrapper &operator=(const OldStructWrapper &) = default;
/// Old struct move constructor
OldStructWrapper(OldStructWrapper &&) = default;
/// Old struct move assignment
/// \return Old struct wrapper
OldStructWrapper &operator=(OldStructWrapper &&) = default;
/// Property x setter
/// \param x value to set
void set_x(int x) {
old_struct_set_x(&os, x);
}
/// Property x getter
/// \return x value
[[nodiscard]] auto get_x() const -> int {
return old_struct_get_x(&os);
}
};
There must be at least 3 lines of code to declare the class, 1 to associate the old structure and 2 lines for each function to be reused. The more lines there are in my code and the less I feel comfortable as a written line is a line to maintain, but it must be admitted here that the addition remains acceptable.
For private implementations, the work is more complex. For aggregation, the compiler can’t know the size in memory at compile time, so you have to use a pointer:
class OldPimplWrapper final {
private:
old_pimpl_t *p_op{nullptr};
// ...
};
The constructor and destructor must then be overridden to allocate the old private implementation and deallocate it:
class OldPimplWrapper final {
// ...
public:
OldPimplWrapper() : p_op{old_pimpl_new()} {};
~OldPimplWrapper() {
old_pimpl_del(p_op);
}
// ...
};
In addition, the copying of data from old private implementations has to be considered when copying the wrappers:
class OldPimplWrapper final {
// ...
public:
// ...
OldPimplWrapper(const OldPimplWrapper &other) : p_op{old_pimpl_new()} {
set_x(other.get_x());
}
OldPimplWrapper &operator=(const OldPimplWrapper &other) {
set_x(other.get_x());
return *this;
}
// ...
As well as moving the memory in the move constructor / assignment of the wrappers:
class OldPimplWrapper final {
// ...
public:
// ...
OldPimplWrapper(OldPimplWrapper &&other) noexcept: p_op{nullptr} {
p_op = other.p_op;
other.p_op = nullptr;
}
OldPimplWrapper &operator=(OldPimplWrapper &&other) noexcept {
p_op = other.p_op;
other.p_op = nullptr;
return *this;
}
// ...
};
Before being able to encapsulate the old functions as in the case of the public structure:
class OldPimplWrapper final {
// ...
public:
// ...
void set_x(int x) {
old_pimpl_set_x(p_op, x);
}
// ...
};
class OldPimplWrapper final {
// ...
public:
// ...
[[nodiscard]] auto get_x() const -> int {
return old_pimpl_get_x(p_op);
}
// ...
};
The OldPimplWrapper
class can therefore be completely explicitly implemented:
/// Old private implementation wrapper
class OldPimplWrapper final {
private:
p_old_pimpl_t p_op{nullptr}; ///< Pointer to old private implementation, null by default
public:
/// Old private implementation constructor
OldPimplWrapper() : p_op{old_pimpl_new()} {};
/// Old private implementation destructor
~OldPimplWrapper() {
old_pimpl_del(p_op);
}
/// Old private implementation copy constructor
/// \param other Old private implementation wrapper to copy
OldPimplWrapper(const OldPimplWrapper &other) : p_op{old_pimpl_new()} {
set_x(other.get_x());
}
/// Old private implementation copy assignment
/// \param other Old private implementation wrapper to copy
/// \return Copy of other
OldPimplWrapper &operator=(const OldPimplWrapper &other) {
set_x(other.get_x());
return *this;
}
/// Old private implementation move constructor
/// \param other Old private implementation wrapper to move
OldPimplWrapper(OldPimplWrapper &&other) noexcept: p_op{nullptr} {
p_op = other.p_op;
other.p_op = nullptr;
}
/// Old private implementation move assignment
/// \param other old private implementation wrapper to move
/// \return Other
OldPimplWrapper &operator=(OldPimplWrapper &&other) noexcept {
p_op = other.p_op;
other.p_op = nullptr;
return *this;
}
/// Property x setter
/// \param x value to set
void set_x(int x) {
old_pimpl_set_x(p_op, x);
}
/// Property x getter
/// \return x value
[[nodiscard]] auto get_x() const -> int {
return old_pimpl_get_x(p_op);
}
};
Here are at least 3 lines of code to declare the class, 1 to associate the old structure and 2 lines for each function to be reused, 1 line for the constructor, 2 for the destructor, at least 5 for copying and 6 for moving, unless they are explicitly deleted with the delete statement, which makes the class maintenance easier, but makes the client integration more complex. Thus, the main drawback of this solution is the more or less important quantity of code to add between the old library and the client, and the cost that this implies in code maintenance.
The end result is valuable, old private structures and implementations can be manipulated as simple classes:
auto os = OldStructWrapper();
os.set_x(42);
const auto X = os.get_x();
auto op = OldPimplWrapper();
op.set_x(42);
const auto X = op.get_x();
And copy / move constructor / assignment help the client with high level memory manipulation, especially for the fan of ‘}
’ as the best destructor.
OldStructWrapper os_cpy_1;
OldStructWrapper os_cpy_2;
{
auto os = OldStructWrapper();
os.set_x(42);
os_cpy_1 = os; // Copy assignment
os_cpy_2 = OldStructWrapper(os); // Copy constructor and move assignment
}
os_cpy_2.set_x(24);
const auto X_1 = os_cpy_1.get_x();
const auto X_2 = os_cpy_2.get_x();
OldPimplWrapper op_cpy_1;
OldPimplWrapper op_cpy_2;
{
auto op = OldPimplWrapper();
op.set_x(42);
op_cpy_1 = op; // Copy assignment
op_cpy_2 = OldPimplWrapper(op); // Copy constructor and move assignment
}
op_cpy_2.set_x(24);
const auto X_1 = op_cpy_1.get_x();
const auto X_2 = op_cpy_2.get_x();
Smart pointers integration
What has just been presented is an integration solution based on the use of classes to hide the complexity of memory management, while providing cleaner access to data manipulation.
Access to data manipulation is just a plus and the key is to improve memory management, and in modern C++
a native solution exists.
It is called smart pointers.
Smart pointers are one of the mechanics of RAII, whose objective is to create a notion of data ownership.
When the owner of a single pointer is destroyed (end of scope or end of life of an object), the single pointer is also destroyed, which is perfect for the fans of ‘}
’ as the best destuctor.
Use of smart pointers is very simple, the declaration of aliases can be done this way:
using UpOldStruct = std::unique_ptr<old_struct>;
Allocation and initialization can be even be done in a single instruction using standard library tools:
std::make_unique<T>(T *);
Such as in the following example:
auto up_os = std::make_unique<old_struct>();
old_struct_set_x(up_os.get(), 42);
const auto X = old_struct_get_x(up_os.get());
For the private implementation, the tools already exist to easily implement the use, the declaration for aliases is done as with a classical structure, specifying that we will provide a handle to the destructor:
using UpOldPimpl = std::unique_ptr<old_pimpl_t, void (*)(p_old_pimpl_t)>;
The creation is done by allocating the memory and providing the connection to the destuctor, and then manipulating the smart pointer like a classical structure pointer:
auto up_op = UpOldPimpl(old_pimpl_new(), old_pimpl_del);
old_pimpl_set_x(up_op.get(), 42);
const auto X = old_pimpl_get_x(up_op.get());
Note: as for now, make_unique
can not be used with destructor overloading.
The same can be done with shared pointers:
std::make_shared<T>(T *);
auto sp_os = std::make_shared<old_struct>();
old_struct_set_x(sp_os.get(), 42);
const auto X = old_struct_get_x(sp_os.get());
auto sp_op = std::shared_ptr<old_pimpl>(old_pimpl_new(), old_pimpl_del);
old_pimpl_set_x(sp_op.get(), 42);
const auto X = old_pimpl_get_x(sp_op.get());

The integration of C

was designed a long time ago and the mechanisms are efficient but spartan, forcing the client code to take care to manage memory and data access.
When integrating into modern C++
, where there is often a culture of good memory management and pointer manipulation, these mechanisms are not comfortable.
There are solutions to interface C

None of these solutions is perfect and all of them have limitations, but they have their advantages that we will summarize in the following paragraph.

| Wrappers | Consistent use, copy and move of memory can be managed, No explicit pointer manipulation for the customer | Additionnal code to implement and maintain |
| Smart pointers | Very little code to implement and maintain, consistent use of smart pointers, clean memory management | Difficult copy, requires the customer to manipulate pointers, make_unique instruction can not be used with private implementation structure |
Final word
For RROSACE
, the simulation model library was written in C89
, and the simulation framework in C++11
.
My first strategy was to use the least amount of code to lighten maintenance, so I preferred smart pointers. Before presenting my work and publishing the code, I revised my strategy and switched to wrapping, which has another implicit advantage, that of not having to explain the mechanics of smart pointers and RAII to the audience.

(Update: Rolling out again) Google Maps is testing a floating scrolling bar of category searches
by Rita El Khoury
Update 1: 2019/08/23 9:21am PDT
One year later, new look
Update 2: 2019/11/04 11:36pm PST
Rolling out
Google is always trying new things with the Maps app's interface, moving items from the side menu to the floating layers button, implementing different designs of the bottom bar in various regions, and lately just dabbling with more and more changes that fall in line with the new Material Design looks. And now we have a new change: a scrolling floating bar of category searches is showing up on the top of the screen.
We've only received one tip of this, so maybe it's a limited test. Reader Max tells us that he's seeing this bar on the latest Google Maps beta, but I can't reproduce it on my devices. The Layers button is moved to the left of the screen and the floating category bubbles can be swiped through to reveal more. The bubbles also look very "Material Design 2.0," if you will, so they may be coming along with the updated Maps that will have all those Assistant and social features announced at I/O.
Currently, six categories are showing up: restaurants, cafes, super markets, gas stations, pharmacies, and hospitals. (I can see the same when I tap the Explore button in the bottom bar on my devices, except hospitals is replaced by ATMs for me.) Tapping on any of the bubbles simply starts a search for it. So there's nothing new, functionality-wise.
Update 1: 2019/08/23 9:21am PDT by Rita El Khoury
One year later, new look
More than a year after first testing them, Google is bringing back these search filters. They look more modern now with cleaner lines, a thicker font, and greyscale icons. And since the filters are the same as the colored category icons in the Explore bottom sheet, those are now gone. Thanks, Bharath Keshav and Zachary Kew-Denniss!
End of Update
Update 2: 2019/11/04 11:36pm PST by Rita El Khoury
Rolling out
In familiar Google fashion, these floating search filters disappeared for a while and are now showing up again on most of our devices. Instead of three icons, though, we get eight (including your home or work location), followed by the catch-all More to find other categories. Thanks, Eduardo, Nick!
End of Update
Thanks:
Max

Sesame StreetSesame Street is the product of the Children's Television Workshop. It features Jim Henson's muppets and teaches children skills such as counting, learning the alphabet, where things come from and so forth. Since many parents regard Sesame Street as a babysitter, millions of children have grown up with Big Bird, Cookie Monster, Oscar the Grouch and the (obviously gay) Ernie and Bert.In 2002 Kami, the first HIV-positive Muppet, was introduced to promote education about HIV/AIDS in Africa and elsewhere. Members of the U.S. Congress took time out from their busy schedules to draft a letter of concern about the show.

6,000 Women Deserted by NRI Partners in Last 4 years
The 'Registration of Marriage of Non-Resident Indian Bill, 2019' empowers passport authorities to impound or revoke passport or travel documents of NRIs who fail to register their marriage within 30 days after getting married.
New Delhi: The ministry of external affairs received over 6,000 complaints of women deserted by their NRI spouses between January 2015 and October this year, minister of state for external affairs V Muraleedharan said in response to a query in the Lok Sabha.
About 1,498 complaints were received in 2017, 1510 in 2016 and 796 in 2015.
This is not a new situation in India. In fact, a sudden spurt in cases of NRI marriage frauds pushed the government to bring the Registration of Marriage or Non-Resident Indian Bill, 2019. It was introduced in the Rajya Sabha by former external affairs minister Sushma Swaraj early this year.
The ‘Registration of Marriage of Non-Resident Indian Bill, 2019’ empowers passport authorities to impound or revoke passport or travel documents of NRIs who fail to register their marriage within 30 days after getting married.
Currently, the Bill has been referred to Parliament’s standing committee on external affairs.
If an NRI man fails to register his marriage within the stipulated time, his passport can be impounded or revoked.
Also, it allows courts to attach properties, movable and immovable, of “proclaimed offenders” or people who fail to appear before courts despite warrants being issued against them.
The proposed law will be applicable to NRIs marrying Indian women within or even outside India, according to the bill.

or you could just use join on the array. like this
['hello','world','!!!'].join(' ') //return "hello world !!!"
or am i missing something?

@ionut: It ensures that the first time in the loop it will use an empty string, but use the glue for subsequent loops.

Hi,
Why do you declare tGlue = glue;
in the loop each time?

Excellent Work...
Well, I already developed one web 2.0 application (For Personal Use)... But Still having problems in mastering JavaScript (Especially JavaScript arrays)...
Bookmarked it for future reference.

@Itsacon: Thanks very much! There may be a few other functions out there like that that only work with true arrays, so it is very good to have your fix. FYI, I declared retVal, tGlue, and i with 'var' so they would not be globals. It is now fixed in git: http://github.com/kvz/phpjs/commit/e00889a7914df1e91640b7222d56eee30c20ec97

This is a follow-up on the discussion at the array_diff() function.
The implode function is currently incompatible with most of the array_xxx() functions. Those functions often return objects instead of Arrays, but the implode() function actively checks for Arrays, and returns objects un-imploded.
I made a slight alteration, parsing all object properties as well.
function implode(glue,pieces)
{
if(arguments.length == 1)
{
pieces = glue;
glue = '';
}
if(typeof(pieces)=='object')
{
if(pieces instanceof Array)
return pieces.join(glue);
else
{
retVal='', tGlue='';
for(i in pieces)
{
retVal += tGlue + pieces[i];
tGlue = glue;
}
return retVal;
}
}
else
{
return pieces;
}
}
I also made the function compatible with the PHP 4.3.0 alteration that made the glue parameter optional.

Today’s computers perform calculations and process information using the standard (or as a physicist would say, “classical”) model of computation, which dates back to Turing and von Neumann. In this model, all information is reducible to bits, which can take the values of either 0 or 1 – and all processing can be performed via simple logic gates (AND, OR, NOT, NAND) acting on one or two bits at a time. At any point in its computation, a classical computer’s state is entirely determined by the states of all its bits, so that a computer with \(n\) bits can exist in one of \(2^n\) possible states, ranging from \(00...0\) to \(11…1\).
The power of the quantum computer, meanwhile, lies in its much richer repertoire of states. A quantum computer also has bits. But instead of 0 and 1, its quantum bits, or qubits, can represent a 0, 1, or both at once, which is a property known as superposition. This on its own is no special thing, since a computer whose bits can be intermediate between 0 and 1 is just an analog computer, scarcely more powerful than an ordinary digital computer. However, a quantum computer takes advantage of a special kind of superposition that allows for * exponentially many* logical states at once, all the states from \(|00...0\rangle\) to \(|11…1\rangle\). This is a powerful feat, and no classical computer can achieve it. The vast majority of these quantum superpositions, and the ones most useful for quantum computation, are entangled—they are states of the whole computer that do not correspond to any assignment of digital or analog states of the individual qubits. While not as powerful as exponentially many classical computers, a quantum computer is significantly more powerful than any one classical computer – whether it be deterministic, probabilistic, or analog. For a few famous problems (such as factoring large numbers), a quantum computer is clearly the winner over a classical computer. A working quantum computer could factor numbers in a day that would take a classical computer millions of years.


Third World Cop (2000) Rating: 3.5 stars out of 5.0 stars
Cast: Paul Campbell, Mark Danvers, Carl Bradshaw, Audrey Reid, Winston Bell, Lenford Salmon, Desmond Ballentine (a.k.a. Ninjaman) Written by: Suzanne Fenn, Chris Browne, and Chris Salewicz Directed by: Chris Browne Running Time: 98 minutes
`We run tings. Tings don't run we.' -Sound advice from Capone (Paul Campbell) to his squaddie (or partner), Floyd (Winston Bell).
Jamaican film, shot entirely on video, featuring a standard cop movie plot mixed with a dash of John Woo-styled brotherhood morals (and a little gunplay).  When he arrives, he discovers that the ghetto where he grew up has gotten worse, thanks mainly to the crime boss Wonie (Jamaican film veteran Carl Bradshaw), so named because his left hand has been amputated and replaced by a grasping hook). Capone discovers that Wonie has been smuggling guns inside shipments of charity supplies for the area churches and, much to his disappointment, also finds out his childhood friend Ratty (Mark Danvers) has been helping him. Torn between doing his job and protecting his best friend, Capone must make some hard decisions in order to make things right again.
Directed deftly by first time Jamaican filmmaker Chris Browne (assistant director for such American films as How Stella Got Her Groove Back and Instinct), one hardly notices the film was shot on video after a while. Shots are handled so efficiently that they quickly take on the nuances of the aforementioned John Woo films, although the action isn't as hyperkinetic as most of Woo's films are. The action scenes are handled with a kind of flair though, and eventually begin to take on a life of their own (beyond the Hong Kong films that they are obviously patterned after). The make-up effects are particularly good in these scenes as well, with flawless squib work on display from the effects team.
The cast is superb and listening to their dialogue, spoken with thick Jamaican accents (half of which have to be subtitled because of their extensive use of slang), just adds to the interest. Paul Campbell, as the `loose cannon' Capone, essays his role perfectly, displaying the right amount of menace and compassion at the right times. Mark Danvers evokes sympathy as Ratty, the part-time gun smuggler who is also trying to help the community by building football fields and organizing block parties to bring people together. Unfortunately, Carl Bradshaw is given the least to do and his character as the crime boss seems ineffective (largely because his underlings seem to run all over him), but then again, that could be the way his character was intended to be portrayed.
The music in the film is composed of all reggae songs, and the soundtrack was produced by Grammy Award winning artists, Sly and Robbie (who have worked with the likes of The Rolling Stones, Maxi Priest, Bob Dylan, James Brown, Grace Jones, Herbie Hancock, Bootsy Collins, and Carly Simon among others). The end credit song, `We Run Tings', by the group Red Dragon, is pretty decent and carries on the theme of the movie established early on by the quote that opens this review. Oddly enough, Desmond Ballentine (who plays the character Deportee) is well known as a pioneer in the realm of `gangsta' reggae as the performer Ninjaman, and he doesn't contribute a single song to the film (that I could see), which is virtually unheard of here in the US.
At the time of this writing, Third World Cop has been put into limited theatrical release in the US, coming off of a six-month box-office breaking run in Jamaica, where it holds the position as highest grossing film of all time (bringing in $21 million in Jamaica, which is roughly $500,000 US). Palm Pictures (the company that released the offbeat, but entertaining Six-String Samurai) is the company releasing the film and considering that their main focus is the DVD market, I can imagine that a disc will be available once the film has left theaters. Chris Blackwell, founder of Palm Pictures, was also involved in the production of another Jamaican box-office smash in 1981 entitled Countryman, so I'd say he has a pretty good track record.
Overall, Third World Cop is a pretty entertaining homage to the films of John Woo, Ringo Lam, Tsui Hark, and many other action films by directors from Hong Kong. If action films are your thing and you don't mind intermittent subtitles, then you can't go wrong with this film. The performances and the story are solid (if only a little cliched) and the action is tight. I'm not sure what the other Jamaican films released in that country are like, but apparently Third World Cop's honors are well deserved.

Secure protocols for password-based user authentication are well-studied in the cryptographic literature but have failed to see wide-spread adoption on the Internet; most proposals to date require extensive modifications to the Transport Layer Security (TLS) protocol, making deployment challenging. Recently, a few modular designs have been proposed in which a cryptographically secure password-based mutual authentication protocol is run inside a confidential (but not necessarily authenticated) channel such as TLS; the password protocol is bound to the established channel to prevent active attacks. Such protocols are useful in practice for a variety of reasons: security no longer relies on users' ability to validate server certificates and can potentially be implemented with no modifications to the secure channel protocol library.
We provide a systematic study of such authentication protocols. Building on recent advances in modelling TLS, we give a formal definition of the intended security goal, which we call password-authenticated and confidential channel establishment (PACCE). We show generically that combining a secure channel protocol, such as TLS, with a password authentication protocol, where the two protocols are bound together using either the transcript of the secure channel's handshake or the server's certificate, results in a secure PACCE protocol.
Our prototype based on TLS is available as a cross-platform client-side Firefox browser extension as well as an Android application and a server-side web application that can easily be installed on deployed web browsers and servers.

Spawn (PG-13) ** (out of ****) Todd McFarlane's comic book sensation Spawn is prime fodder for a big-budget Hollywood movie treatment--there's a extravagantly costumed, supernaturally powered, sometimes homicidal hero, resurrected from the dead, whose primary enemy is none other than the devil himself. After years of topping comic sales charts, Spawn has indeed arrived to conquer the movie arena, but something is seriously lacking; for all its visual razzle dazzle, Mark Dippe's film is a mess--a misguided attempt to sanitize a concept whose most distinctive trait is its darkness. To Dippe and scripter Alan McElroy's credit, McFarlane's basic conceit remains intact: Spawn (Michael Jai White) was originally murdered government agent Al Simmons (Michael Jai White) who makes a pact with the devil to see beloved wife Wanda (Theresa Randle) one more time. In return, however, he must use his newfound supernatural powers to lead Hell's Army in its quest to destroy Heaven and Earth. Prodding Spawn into serving holding up his end of the bargain is the Clown (John Leguizamo, having a ball in a fat suit and heavy makeup), whose short, rotund exterior hides his true, horrific self as the demonic Violator; urging him to rebel against the dark side is Cogliostro (Nicol Williamson), a mysterious figure from the distant past. The above is a fairly accurate distillation of comic's basics, but the Spawn faithful know there is something deeper and richer behind the plot fundamentals--an overwhelming sense of despair and anguish. Spawn has a great costume, some nifty powers, and a killer instinct, but the key to the character is his emotional torment. Al's passionate love for Wanda is what drives him and also what cripples him. Merely seeing her is not enough, and being with her is an impossibility--not only because he's a severely burned undead hellspawn but because she has gone on with her life. Adding to his angst is the fact that in the five years that have passed between his death and rebirth, Wanda is remarried with a daughter, Cyan (Sydni Beaudoin), and her new husband is none other than Al's best friend, Terry Fitzgerald (D.B. Sweeney, putting a Caucasian face on a what is originally an African-American character). For reasons only known to him, the intense emotional content that McElroy successfully incorporated into the Spawn HBO animated series (which, I may add, is a much more satisfying translation) is all but completely absent in his script for the film. The only hints at Spawn's torment are a couple of anguished cries of "Wanda," and the rest of the time--which is nearly all of the time--he's merely angry and vengeful, no different from some heroes in any number of generic action films. The dilution of the emotion--and, in McElroy's most offensive move, having the normally brooding Spawn utter a couple of lame _one-liners_--are obvious attempts to make the character fit a more traditional mold and hence win an audience-friendly PG-13 rating. But this decision makes no sense, since it's Spawn's untraditional, dark, R-rated nature that made him so interesting to begin with. Dippe, making his feature directorial debut, is a seasoned special effects creator, so it should come as no surprise that Spawn is most impressive and imaginative--and most faithful--in the visual arena. The jarring opening credits, complete with shaky, distorted lettering and nearly subliminal glimpses of images, is highly reminiscent of Se7en's unsettling main titles (which is a good thing). The creative transitions between scenes, such as having flames and capes wipe across the frame, effectively recall the visual style of the comic, as do the characters' appearances. The Clown and his demonic alter ego, the Violator, are every bit as repellent in three-dimensions as they are on the page (even if, as part of the PG-13 compromise, he does not perform any of his trademark heart extractions), and Spawn is blessed with a wonderfully fluid, computer-generated cape, which, unfortunately, only materializes from time to time. McFarlane has said that the cape's sporadic appearance in the film (Spawn has his cape at all times in the comic and animated series) was a conscious decision, so Spawn would look less "superhero-y." Ironically, though, he looks more conventional without it. The true marvel is Dippe and visual effects supervisor Steve "Spaz" Williams's vision of hell, a stunningly organic blend of flame and rock--a true technical achievement. But that's the problem with Dippe's direction as a whole--it's _too_ technical. Attention was paid to the visuals and little else. The story, involving a biological weapon developed by Jason Wynn (Martin Sheen, all clenched teeth), the shady government agent responsible for Al's death, is weak and doesn't make complete sense; even the action scenes are clumsily handled, especially the climactic battle in hell, where the heavy editing makes the action hard to follow. But worst of all, there's no passion--no real connection to the characters (no fault to White or the other actors, who aren't really given much to work with in the script), no sense of urgency to the tale. The film is a feast for the eyes, yes, but there's none of the soul that gives the comic its power. In its comic and animated form, Spawn pushes the creative envelope; in this live-action, big-screen incarnation, Spawn plays it safe--much too safe; so safe that I'm certain people being introduced to Spawn with this movie will wonder just what all the fuss is about. At a recent comic book convention, producer Clint Goldman said with much confidence and certainty, "There _will_ be a sequel." Here's hoping that next time around the filmmakers will take a lesson from its hero in the comic and go for the kill.

55% off these wireless Marshall headphones
by https://www.facebook.com/LouderPosts/£120 off these super cool cans from the daddies of modern amplication
Black Friday might be days away but the sales have started now.
These Marshall Monitor wireless headphones should be a consideration for any rock fan looking for a new pair of bluetooth headphones.
Marshall pretty much invented the modern rock sound back in the 60s, working directly with artists like The Who's Pete Townshend or a young Eric Clapton. Since then, their amps and cabs (aka speakers) have been the first port of call for every rock act worth their salt. The logo and black leatherette-with-gold look is iconic.
But they haven't lasted more than 50 years based on looks alone.
These Marshall Monitor over-ears are designed with the same stellar attention to detail as seen in Marshall's stage audio equipment, and they possess impressive sound capabilities: full-bodied, with deep lows, mids that shine and crystal highs. They're comfortable, give you 30 hours of performance and look the bollocks (technical term).
Marshall Monitor bluetooth headphones: were £220, now £98 at Amazon
Soulful sound performance, big on comfort and with those iconic rock'n'roll good looks, this is a great chance to snap up premium headphones for a much more affordable price. Hell, they sure beat Beats. View Deal
