FAREWELL MY CONCUBINE is a story that spans fifty-three years, presenting the lives of two men against the historical backdrop of a country in upheaval. Initially banned in China but shown to international acclaim, Chen Kaige's film is one of the year's few true masterpieces. Deserving of its award at Cannes and of its prominent position in 1993's New York Film Festival, FAREWELL MY CONCUBINE is a motion picture experience that few will soon forget after leaving the theater.
In Beijing of 1924, the youthful Douzi and Shitou are brought together under the thumb of the strict master of a small acting troupe. It becomes quickly apparent that these are the most talented of the master's pupils, and he pushes them harder than his other students.  Douzi, now going by the name of Chen Dieyi (Leslie Cheung), and Shitou, called Duan Xiadlou (Zhang Fengyi), are major opera stars, and their production, "Farewell My Concubine" is nationally known. The two are inseparable, until the woman Juxian (Gong Li) comes between them.
FAREWELL MY CONCUBINE is neatly divided into eight chapters, including a prologue and epilogue in 1977 that bookend the story. Each section represents a different era in both Chinese history and the lives of the characters. The historical background--from the time of the Warlords through the Cultural Revolution, including the Japanese invasion of 1937 and the Communist takeover, is more than window dressing. It is integral to the plot, its thread as important to the overall weaving as any other.
The first portion of the film is devoted to the early lives of Dieyi and Xiadlou as they form an unshakable bond under the often-cruel punishments of their master. Years later, when we meet them again as well-known actors, the bond has only strengthened. These two are as close as men can be--yet Dieyi wishes for even greater intimacy.
The subject of homosexuality is only once overtly referred to in FAREWELL MY CONCUBINE, but its presence is at once subtle and obvious. While Xiadlou remains blissfully unaware of the nature of his friend's love for him, Dieyi is tortured by it. The introduction of Juxian, a prostitute who becomes the potential future wife of Xiadlou, creates a moral dilemma for Dieyi that he is never able to completely resolve.
Chen Kaige has done a fabulous job portraying these various relationships with depth, sensitivity, and realism. This is no occasionally melodramatic JOY LUCK CLUB, but a real and powerful illustration of human interaction that shows the layers of hatred and love built into the contact between the three principals (and especially the two friends). Just when you think you understand all the facets of the relationships, something else is uncovered. Character development of this sort is almost unheard-of in today's movies.
Dieyi is the most fascinating character. From the beginning, his sense of identity is confused. Not only is he attracted to men, but his role as a woman in "Farewell My Concubine" creates a certain ambivalence about his own gender. In childhood, the refrain of "I am a girl" is drilled into him so that he can effectively assume the role of the concubine in the opera but, as another character observes, the line between reality and acting has become blurred.  It's no wonder that his soul is so tortured.
Xiadlou is a more straightforward personality--at least on the surface. Nevertheless, through his ever-changing relationships with Dieyi and Juxian, he proves that apparent simplicity often hides strong currents. It is eventually one of his actions that propels this movie to its literal and emotional climax.
 Starting out as a wedge between the two friends, Juxian ends up a crucial element in their relationship.
It's no wonder that this film was initially banned in China (although the government eventually relented and there was one showing; more may be forthcoming). The Communist movement is not shown in a positive light. While not specifically a force for evil, Communist attitudes contribute to one of the movie's most emotionally-shocking scenes.
Those unfamiliar with twentieth-century Chinese history are in for something of a crash course. No film can ever hope to convey the complex mosaic of cultural upheaval caused by everything that happened between 1924 and 1977, but FAREWELL MY CONCUBINE does an excellent job presenting samples of the flavor. Americans viewing this picture will find some portions difficult to follow because of cultural differences, but they will ultimately gain more than they lose.
If there is a down side to FAREWELL MY CONCUBINE, it's that several scenes, as well as the motion picture as a whole, run on a little too long. This is a minor quibble, however, and one easily endured considering the high quality of the finished product. Better to cut judiciously than to hack out something important.
The only member of the cast likely to be known to (some) American viewers is Gong Li, whose credits include RAISE THE RED LANTERN and THE STORY OF QUI JU. She is, as usual, excellent, but no more so than her two co-stars, both of whom effectively realize difficult and complex personalities. For the supporting actors, there's not a weak performance to be found.
Sadly, there are some for whom this movie will turn out to be a dreadful bore. First and foremost, it requires more than two hours and thirty minutes of reading subtitles, which a disproportionate number of viewers find distracting (if not offensive). Secondly, while there are bursts of often-passionate action, the pace of FAREWELL MY CONCUBINE is leisurely, allowing time for characters and situations to breathe.
Certainly among the best films of 1993, FAREWELL MY CONCUBINE can stand up favorably to any of the other contenders. It is also, in my opinion, the best Chinese film ever to reach these shores. I haven't seen any of Chen Kaige's other films (I believe this is his fifth or sixth directorial effort, and the first to get widespread international distribution) but, on the strength of what he has accomplished with this picture, I'll be on the lookout for his next project. If it's half as good as FAREWELL MY CONCUBINE, it will still be a worthy effort.

Tcpreplay1 was designed to replay traffic previously captured in the pcap format back onto the wire for testing NIDS and other passive devices. Over time, it was enhanced to be able to test in-line network devices. However, a re-occurring feature request for tcpreplay is to connect to a server in order to test applications and host TCP/IP stacks. It was determined early on, that adding this feature to tcpreplay was far too complex, so I decided to create a new tool specifically designed for this.
Flowreplay is designed to replay traffic at Layer 4 or 7 depending on the protocol rather then at Layer 2 like tcpreplay does. This allows flowreplay to connect to one or more servers using a pcap savefile as the basis of the connections. Hence, flowreplay allows the testing of applications running on real servers rather then passive devices.
Flowreplay must be able to process multiple connections to one or more devices. There are two options:
Although using libpcap/libnet would allow more simultaneous connections and greater flexibility, there would be a very high complexity cost associated with it. With that in mind, I've decided to use sockets to send and receive data.
Because a pcap file can contain multiple simultaneous flows, we need to be able to support that too. The biggest problem with this is reading packet data in a different order then stored in the pcap file.
Reading and writing to multiple sockets is easy with select() or poll(), however a pcap file has it's data stored serially, but we need to access it randomly. There are a number of possible solutions for this such as caching packets in RAM where they can be accessed more randomly, creating an index of the packets in the pcap file, or converting the pcap file to another format altogether. Alternatively, I've started looking at libpcapnav5 as an alternate means to navigate a pcap file and process packets out of order.
Knowing when to start sending client traffic in response to the server will be "tricky". Without understanding the actual protocol involved, probably the best general solution is waiting for a given period of time after no more data from the server has been received. Not sure what to do if the client traffic doesn't elicit a response from the server (implement some kind of timeout?). This will be the basis for the default plug-in.
Dealing with IP fragmentation and TCP stream reassembly will be another really complex problem. We're basically talking about implementing a significant portion of a TCP/IP stack. One thought is to use libnids6 which basically implements a Linux 2.0.37 TCP/IP stack in user-space. Other solutions include porting a TCP/IP stack from Open/Net/FreeBSD or writing our own custom stack from scratch.
The biggest asynchronous problem, that pcap files are serial, has to be solved in a scaleable manner. Not much can be assumed about the network traffic contained in a pcap savefile other then Murphy's Law will be in effect. This means we'll have to deal with:
There are five major complications with flowreplay:
Missing packets in the pcap file will probably make that flow unplayable. There are proabably certain situation where we can make an educated guess, but this is far too complex to worry about for the first stable release.
That still leaves creating a basic TCP/IP stack in user space. The good news it that there is already a library which does this called libnids. As of version 1.17, libnids can process packets from a pcap savefile (it's not documented in the man page, but the code is there).
A potential problem with libnids though is that it has to maintain it's own state/cache system. This not only means additional overhead, but jumping around in the pcap file as I'm planning on doing to handle multiple simultaneous flows is likely to really confuse libnids' state engine. Also, libnids is licensed under the GPL, but I want flowreplay released under a BSD-like license; I need to research if the two are compatible in this way.
Possible solutions:
As earlier stated, one of the main goals of this project is to keep things single threaded to make coding plugins easier. One caveat of that is that any function which blocks will cause serious problems.
There are three major cases where blocking is likely to occur:
It is possible to do non-blocking IO on sockets by setting the O_NONBLOCK flag on a socket file descriptor using fcntl(2). Then all operations that would block will (usually) return with EAGAIN (operation should be retried later); connect(2) will return EINPROGRESS error. The user can then wait for various events via poll(2) or select(2).7If connect() returns EINPROGRESS, then we'll just have to do something like this:
if (getsockopt(conn->s, SOL_SOCKET, SO_ERROR, &e, &len) < 0) {
/* not yet */
if(errno != EINPROGRESS){ /* yuck. kill it. */
log_fn(LOG_DEBUG,"in-progress connect failed. Removing.");
return -1;
} else {
return 0; /* no change, see if next time is better */
}
}
/* the connect has finished. */
Note: It may not be totally right, but it works ok. (that chunk of code gets called after poll returns the socket as writable. if poll returns it as readable, then it's probably because of eof, connect fails. You must poll for both.
As stated before, the pcap file format really isn't well suited for flowreplay because it uses the raw packet as a container for data. Flowreplay however isn't interested in packets, it's interested in data streams8 which may span one or more TCP/UDP segments, each comprised of an IP datagram which may be comprised of multiple IP fragments. Handling all this additional complexity requires a full TCP/IP stack in user space which would have additional feature requirements specific to flowreplay.
Rather then trying to do that, I've decided to create a pcap preprocessor for flowreplay called: flowprep. Flowprep will handle all the TCP/IP defragmentation/reassembly and write out a file containing the data streams for each flow.
A flow file will contain three sections:
At startup, the file header is validated and the data stream indexes are loaded into memory. Then the first data stream header from each flow is read. Then each flow and subsequent data stream is processed based upon the timestamps and plug-ins.
Plug-ins will provide the ``intelligence'' in flowreplay. Flowreplay is designed to be a mere framework for connecting captured flows in a flow file with socket file handles. How data is processed and what should be done with it will be done via plug-ins.
Plug-ins will allow proper handling of a variety of protocols while hopefully keeping things simple. Another part of the consideration will be making it easy for others to contribute to flowreplay. I don't want to have to write all the protocol logic myself.
Each plug-in provides the logic for handling one or more services. The main purpose of a plug-in is to decide when flowreplay should send data via one or more sockets. The plug-in can use any non-blocking method of determining if it appropriate to send data or wait for data to received. If necessary, a plug-in can also modify the data sent.
Each time poll() returns, flowreplay calls the plug-ins for the flows which either have data waiting or in the case of a timeout, those flows which timed out. Afterwords, all the flows are processed and poll() is called on those flows which have their state set to POLL. And the process repeats until there are no more nodes in the tree.
Initially, flowreplay will ship with one basic plug-in called ``default''. Any flow which doesn't have a specific plug-in defined, will use default. The goal of the default plug-in is to work ``good enough'' for a majority of single-flow protocols such as SMTP, HTTP, and Telnet. Protocols which use encryption (SSL, SSH, etc) or multiple flows (FTP, RPC, etc) will never work with the default plug-in. Furthermore, the default plug-in will only support connectionsto a server, it will not support accepting connections from clients.
The default plug-in will provide no data level manipulation and only a simple method for detecting when it is time to send data to the server. Detecting when to send data will be done by a ``no more data'' timeout value. Basically, by using the pcap file as a means to determine the order of the exchange, anytime it is the servers turn to send data, flowreplay will wait for the first byte of data and then start the ``no more data'' timer. Every time more data is received, the timer is reset. If the timer reaches zero, then flowreplay sends the next portion of the client side of the connection. This is repeated until the the flow has been completely replayed or a ``server hung'' timeout is reached. The server hung timeout is used to detect a server which crashed and never starts sending any data which would start the ``no more data'' timer.
Both the ``no more data'' and ``server hung'' timers will be user defined values and global to all flows using the default plug-in.
Each plug-in will be comprised of the following:

Wisconsin board backs away from free speech restrictions
DARLINGTON, Wis. - A county board in southern Wisconsin has backed away from a plan to prosecute journalists over their reporting on a water quality study and discipline elected officials for how they handle information about the research.
The Lafayette County Board on Tuesday night put off a decision on how to release information about private wells contaminated with fecal matter.
The board shelved a resolution that said journalists would be prosecuted if they didn't quote a county news release verbatim when reporting on water quality. It also had threatened to punish officials who talked publicly without getting government permission.
The proposals drew criticism for violating First Amendment protections for freedom of speech.
The Journal Sentinel says county board Chairman Jack Sauer threatened to throw out critical members of the public at the meeting and accused attendees of being Democrats.

Orientation Changes in iOS 6
In a current project, I had the need to have one specific view controller present its view in landscape orientation only. Pre-iOS 6, I would have overridden the shouldAutoRotateToInterfaceOrientation
method and returned UIInterfaceOrientationLandscape
. In iOS 6, this method is deprecated. I began researching how orientation issues should be handled going forward, and here is the way I made my specific scenario work.
In iOS 6, the system queries the topmost visible view controller to see if it should rotate. The viewcontroller can override 2 methods to answer this query correctly:
supportedInterfaceOrientations:
shouldAutoRotate
It would seem simple enough to override these methods on each view controller that had special requirements for presentation to have them determine their orientation. The problem arose for me when I had a navigation controller thrown into the mix. Since technically the topmost view controller in a navigation stack is the navigation controller itself, iOS was ignoring the method overrides I had in place for the individual view controllers. It was sending the message directly to my UINavigationController, which did not provide the settings I needed.
I solved this issue by subclassing UINavigationController and overriding the previously mentioned methods, then passing the results from the navigation controller down into the top view controller via the topViewController
property. Here are the steps to accomplish this:
- Create a subclass of
UINavigationController
- Override the following methods:
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
-(NSUInteger)supportedInterfaceOrientations
-(BOOL)shouldAutorotate
- Return the result of each of these operations by passing in the value from the result of calling that method on the topViewControllerof the UINavigationController
- Implement any or all of those methods specific to your needs on your UIViewController subclasses
- Make sure you are using your
UINavigationController
subclass in place of the standardUINavigationController
- My project uses storyboards, so I simply specified my UINavigationController subclass in the Identity Inspector
Here is my implementation of the navigation controller subclass in its entirety:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
|
Then, in my specific view controller that needs to be launched in landscape, I overrode this method and returned the appropriate value:
1 2 3 4 |
|
That’s really all there was to it. The research to get this right took much longer than the implementation.
Please contact me with any questions, and good luck.

I decided to talk about Ruby classes and attributes because I believe this is subject difficult to grasp. Seeing is sometimes better than hearing, so let's compare two different ways of creating a "Refrigerator class.
For my comparison, I created two refrigerators with the same shelves and food inside.
What do we see?
If you look closely at the shorter way to create our Refrigerator class, we see that when we ask for what is in our refrigerator, one items is shown with a negative quantity (mushroom pack). This is because there is no control, the person has total liberty to make changes as he/she wants due to attribute accessor quality we have given.
On the other hand, the longer way to create the class includes methods and within one of the methods we are preventing someone from deleting more items than there are.
I did it by incorporing in my method: "if @top_shelf[item] < quantity puts "There is only #{top_shelf[item]} on the shelf"
Another thing worth mentioning is the way we are adding and deleting food items in the refrigerator as well how we are interrogating about the refrigerator's content.I personally find the class with method to be easier to understand, we don;t need to remember that we need sqaure bracket and an equal. But then, in these cases, we need to remember the name of the method and the number of arguments required. So, you can see, it is not perfect too...
Notes related to the first way to create a class.
Note 1: The refrigerator name is an attribute reader because nobody can change its name once created.
Note 2: These are attribute accessor meaning you can read or write what you want.
Note 3: We are creating an empty list having a key, the name of the food, and a variable, the quantity for the said food.
Note 4: In this instance, the key is the milk, the variable is the 2
Note 5: The program did exactly what the person said, even if it doesn't make sense to take out more than is in the refrigerator => there is no control in place
Notes related to the second way to create a class.
Note a: # They are attribute reader because nobody can change them once they have been created. You cannot change their name.
Note b: When we call the method add, we need to provide it with 3 arguments.
Note c: The case must have the name of the variable we are casing.
Note d: When we call the method delete, we need to provide it with 3 arguments.
Note e: The case must have the name of the variable we are casing.
Note f: We are calling the method add for our downstairs refrigerator.
Note g: We are calling the method delete for our downstairs refrigerator.
Note h: A message is printed for us but the program did not do anything else about it because we did not give any other instructions.

Search off Queensland coast for missing diver
by Sonia KohlbacherA search will resume for a spear fishing free diver who failed to resurface in waters near Bundaberg.
The man, 38, was reported missing by his boat's skipper about 8am on Saturday after diving off the a six-metre vessel about 14 nautical miles off Elliott Heads.
A search resumed at first light on Sunday after an aerial and water search failed to find the man earlier.

django-generic-images is a generic images pluggable django app.
This app provides image model (useful managers, methods and fields) that can be attached to any other Django model using generic relations. It also provides admin multi-image uploader (based on GearsUploader ) with client-side image resizing, animated progress bar and before-upload image previews.
Requirements: django 1.1 (or trunk).
django-composition is required if you want to use ImageCountField or UserImageCountField.
There is an image gallery app (django-photo-albums) based on django-generic-images.
$ pip install django-generic-images
or:
$ easy_install django-generic-images
or:
$ hg clone http://bitbucket.org/kmike/django-generic-images/
$ cd django-generic-images
$ python setup.py install
Then add ‘generic_images’ to your INSTALLED_APPS in settings.py and run
$ manage.py syncdb
If you want ImageCountField and UserImageCountField then follow installation instructions at http://bitbucket.org/daevaorn/django-composition/ to install django-composition.
For admin uploader to work generic_images folder from generic_images/media/ should be copied to project’s MEDIA_ROOT.
The idea is to provide an infrastructure for images that can be attached to any django model using generic relations.
Bases: generic_images.models.ReplaceOldImageModel, generic_utils.models.GenericModelBase
Abstract Image model that can be attached to any other Django model using generic relations.
Override this in proxy subclass to customize upload path. Default upload path is /media/images/<user.id>/<filename>.<ext> or /media/images/common/<filename>.<ext> if user is not set.
<filename> is returned by get_file_name() method. By default it is probable id of new image (it is predicted as it is unknown at this stage).
Simple abstract Model class with image field.
Bases: generic_images.models.BaseImageModel
Abstract Model class with image field. If the file for image is re-uploaded, old file is deleted.
Form for AttachedImage model to be used in inline admin
alias of _AttachedImageAdminForm
InlineModelAdmin for attached images. Adds multi-image uploader with progress bar, before-upload image previews and client-side resizing. Uploader is based on GearsUploader (http://bitbucket.org/kmike/gearsuploader/) project.
To make this work copy generic_images folder from generic_images/media/ to your MEDIA_ROOT. Then use AttachedImagesInline class for you inlines:
#admin.py
from django.contrib import admin
from generic_images.admin import AttachedImagesInline
class MyModelAdmin(admin.ModelAdmin):
inlines = [AttachedImagesInline]
admin.site.register(MyModel, MyModelAdmin)
Just before standard formset the following uploader is displayed:
Gears plugin is here
Message is displayed if Gears plugin is not available
User can select several files at once using Ctrl or Shift keys (Cmd on Mac) in standard OS file selection dialog. He can also remove images from selection by clicking on thumbnails. Several files can also be selected by opening file selection dialog several times.
User presses ‘Upload’ button and upload process begins
By default the ‘Resize ..’ checkbox is unchecked and the input field is blank. If it is unchecked then images are not resized before uploading. User can check it and set his max image width.
In order to set the default value and mark the checkbox as checked by default create customized AttachedImagesInline class using attachedimages_inline_factory() function. This function can also be used to change uploader language (language auto-discovering is not implemented):
from generic_images.admin import attachedimages_inline_factory
class MyModelAdmin(admin.ModelAdmin):
inlines = [attachedimages_inline_factory(lang='ru', max_width=1024)]
admin.site.register(MyModel, MyModelAdmin)
alias of _AttachedImagesInline
Bases: generic_utils.managers.GenericModelManager
Manager with helpful functions for attached images
Useful manager for models that have AttachedImage (or subclass) field and ‘injector=GenericIngector()’ manager.
Bases: django.forms.models.ModelForm
Simple form for AttachedImage model with image and caption fields.
django-generic-images provides fields for storing information about attached images count. Value is stored in model that images are attached to. Value is updated automatically when image is saved or deleted. Access to this value is much faster than additional “count()” queries.
Field with model’s attached images count. Value of this field is updated automatically when image is added or removed. Access to this field doesn’t produce additional ‘select count(*)’ query, data is stored in table.
Example 1:
from generic_images.fields import ImageCountField
class MyModel1(models.Model):
#... fields definitions
image_count = ImageCountField()
Example 2:
class MyModel2(models.Model):
#... fields definitions
image_count = ImageCountField(native=models.IntegerField(u'MyModel2 Images count', default=0))
Field that should be put into user’s profile (AUTH_PROFILE_MODULE). It will contain number of images that are attached to corresponding User.
This field is useful when you want to use something like ImageCountField for User model. It is not possible to add a field to User model without duck punching (monkey patching). UserImageCountField should be put into user’s profile (same model as defined in AUTH_PROFILE_MODULE). It will contain number of images that are attached to corresponding User. FK attribute to User model is considered 'user' by default, but this can be overrided using user_attr argument to UserImageCountField constructor. As with ImageCountField, UserImageCountField constructor accepts also native argument - an underlying field.
Recalculate all ImageCountField and UserImageCountField fields in object obj.
This should be used if auto-updating of these fields was disabled for some reason.
To disable auto-update when saving AttachedImage instance (for example when you need to save a lot of images and want to recalculate denormalised values only after all images are saved) use this pattern:
image = AttachedImage(...)
image.send_signal = False
image.save()
Base class for reusable apps. The approach is similar to django AdminSite. For usage case please check photo_albums app.
Make regex string for PluggableSite urlpatterns: prepend url with parent object’s url and app name.
See also: http://code.djangoproject.com/ticket/11559.
This method should return url patterns (like urlpatterns variable in urls.py). It is helpful to construct regex with make_regex() method. Example:
return patterns('photo_albums.views',
url(
self.make_regex('/'),
'show_album',
{'album_site': self},
name = 'show_album',
),
)
Use it in urls.py. Example:
urlpatterns += patterns('', url(r'^my_site/', include(my_pluggable_site.urls)),)
It is a function that returns decorator factory useful for PluggableSite views. This decorator factory returns decorator that do some boilerplate work and make writing PluggableSite views easier. It passes PluggableSite instance to decorated view, retreives and passes object that site is attached to and passes common context. It also passes and all the decorator factory’s keyword arguments.
For example usage please check photo_albums.views.
Btw, this decorator seems frightening for me. It feels that “views as PluggableSite methods” approach can easily make this decorator obsolete. But for now it just works.
Abstract base class for models that will be attached using generic relations.
RelatedInjector but for GenericForeignKey’s. Manager for selecting all generic-related objects in one (two) SQL queries. Selection is performed for a list of objects. Resulting data is aviable as attribute of original model. Only one instance per object can be selected. Example usage: select (and make acessible as user.avatar) all avatars for a list of user when avatars are AttachedImage’s attached to User model with is_main=True attributes.
Example:
from django.contrib.auth.models import User
from generic_images.models import AttachedImage
users = User.objects.all()[:10]
AttachedImage.injector.inject_to(users, 'avatar', is_main=True)
# i=0..9: users[i].avatar is AttachedImage objects with is_main=True.
# If there is no such AttachedImage (user doesn't have an avatar),
# users[i].avatar is None
One can reuse GenericInjector manager for other models that are supposed to be attached via generic relationship. It can be considered as an addition to GFKmanager and GFKQuerySet from djangosnippets for different use cases.
field_name is the attached object attribute name
All other kwargs will be passed as arguments to queryset filter function.
Example: you have a list of comments. Each comment has ‘user’ attribute. You want to fetch 10 comments and their authors with avatars. Avatars should be accessible as user.avatar:
comments = Comment.objects.all().select_related('user')[:10]
AttachedImage.injector.inject_to(comments, 'avatar', lambda obj: obj.user, is_main=True)
Manager with for_model method.
Manager that can emulate select_related fetching reverse relations using 1 additional SQL query.
field_name is the attached object attribute name
All other kwargs will be passed as arguments to queryset filter function.
For example, we need to prefetch user profiles when we display a list of comments:
# models.py
class UserProfile(models.Model):
user = models.ForeignKey(User, unique=True)
info = models.CharField(max_length=100)
objects = models.Manager()
injector = RelatedInjector(fk_field='user')
# views.py
def show_comments(request, obj_id):
...
comments = list(Comment.objects.for_model(obj).select_related('user'))
UserProfile.injector.inject_to(comments, '_profile_cache',
lambda comment: comment.user)
return direct_to_template('comment_list.html', {'comments': comments})
# in comment_list.html
{% for comment in comments %}

{{ comment.user }}

{{ comment.user.get_profile.info }}

{{ comment.comment|linebreaks }}
{% endfor %}
comment.user attribute will be selected using select_related and comment.user._profile_cache (exposed by get_profile method) will be selected by our injector. So there will be only 2 SQL queries for selecting all comments with users and user profiles.
TestCase for view testing

How do you calculate the best points to use?
We compute each points' expected positive improvement (see page 8 of this paper). To quote the paper:
"it offers an automatic tradeoff between exploitation (focusing on known good parts of the space) and exploration (gathering more information in unknown parts of the space)"
What about multiple objective values?
While it would be possible to model/optimize for multiple objective values, we believe that is is unnecessary. When it comes to making a decision, each of the multiple objectives will have to be combined together to rank the choices, hence that combination having to occur either way. We just require it to happen explicitly.
How can random search possibly be better than A/B testing?
A common complaint in our experience and those we have spoken to is that a majority of parameters tested are unimportant. By testing multiple parameters at the same time, one can explore the possible options for the important variables much more quickly.
Imagine there are 99999 useless parameters to test, and one good one. A grid search (A/B test) would have search through each parameter individually, while random search can search through values of the good parameter with every experiment.
For more information on the merits of random search, see this paper.
Why not just use random search then?
Because we can do better! Random search can be very dumb when it comes to searching through parameter space, since it doesn't take into account any history. By taking historic results into account, we can guide the search areas with known good behavior (to search more thoroughly and try to improve on our best) or areas that are poorly explored (since we have little to no information on how good those parameters would behave).
Initially, parameters will just be randomly spread out through the search space. After a bit of initial exploration is completed, we train a model to learn which areas of the search space are most promising. We then sample a very large number of points from the search space, evaluate which of those points would result in the largest expected improvement, and use the top few of those points as future parameters.
As an interesting side effect of this implementation, we can combine personalization and A/B testing into the same step, and optimize the variables that one would A/B test for based on user features.
- Start a new experiment, or enter the id of an existing one.
- Enter the schema for your dataset.
- Send GET requests to your experiment's sample url to get a set of parameters to use.
- Send POST requests with the _id of those parameters and the result of your objective function (with key _obj) to the same url.
That's it. The parameters should get better and better over time. Feel free to change the schema at any time (make sure each parameter has a unique name) and look at the visualizations to see the results so far.

public interface ControlService
Different implementations of the control service provide the mechanism
to execute methods of the control interfaces. For example
JMXControlService
registers the MBeans in the JMX platform MBean server.
The control service is intended to allow remote execution of a control interface
through any mechanism. The control service provides operations and attributes
similar to JMX. It does not provide notifications.
An instance of a control service MBean is defined by its:
A remote system should be able to specify an operation on an
control server MBean though its alias and type. For example
an application might be submitted with a fixed name
PumpAnalytics (as its alias)
to allow its JobMXBean
to be determined remotely using a combination of
JobMXBean.TYPE
and PumpAnalytics.
Control service implementations may be limited in their capabilities,
for example when using the JMX control service the full capabilities
of JMX can be used, such as complex types in a control service MBean interface.
Portable applications would limit themselves to a smaller subset of
capabilities, such as only primitive types and enums.
The method Controls.isControlServiceMBean(Class)
defines
the minimal supported interface for any control service.

MSR 1.0 is an XML Schema implementation derived from ISO Geographic Information - Metadata - Part 1: Fundamentals. It includes elements for describing spatial representations of resources. The XML schema was encoded using the encoding rules described in ISO/TS 19139:2007, Clause 8.
NOTE: The namespace URI of Metadata for Spatial Representation (MSR) Version: 1.0 doesn't reflect the version number of the XML Schema Implementation. The policy of ISO/TC 211 has evolved in order to reflect the versioning of the XML Schema Implementation as part of the namespace URI.
msr.xsd is the root XML Schema document, i.e., the XML Schema document to be referenced by XML documents containing XML elements in the msr 1.0 namespace or by XML Schema documents importing the msr 1.0 namespace. This XML schema includes (indirectly) all the implemented concepts of the msr namespace, but it does not contain the declaration of any types.
NOTE: The XML Schemca for msr 1.0 are available here as part of a zip archive regrouping all the XML Schema Implementations defined in ISO/TS 19139:2007. They are also available for remote access on the ISO ITTF Repository.
spatialRepresentation.xsd implements the UML conceptual schema defined in ISO 19115-1, 6.5.7. It was created using the encoding rules defined in ISO 19118 and extended in ISO 19139 and contains the following classes: MD_CellGeometryCode, MD_Dimension, MD_DimensionNameTypeCode, MD_GeometricObjectTypeCode, MD_GeometricObjects, MD_Georectified, MD_Georeferenceable, MD_GridSpatialRepresentation, MD_PixelOrientationCode, AbstractMD_SpatialRepresentation, MD_TopologyLevelCode, and MD_VectorSpatialRepresentation

One thing I found very interesting in Shereef's chat was his take on expectations of learning, and the frame of mind that they lead to. Shereef refers to this with a restaurant metaphor, talking about the way a consumer of looks at education; like a customer ordering a set of skills, they pay their money and consume the education. He compares this to the idea of a group of chefs, all of very different experiences, in a kitchen working together to create something. The concept that education as something we do together is something which I think is largely overlooked in mainstream education, instead the focus more often turns to specific skills or abilities which you (idividually) need to learn to pass a test or qualify for a specific standard. I really like EDA's ethos that this is a shared experience, primarily between you and your cohort, but also with the teaching staff of EDA and all of the other people who help along the way.
I feel that I have personally previously been a part of both types of environment, and while there are certainly some advantages of each, I far prefer the kitchen to the table. It's easy to work on a project by yourself, taking your experiences and skills and putting them into action but working with a group of strangers, all with different life experiences, different values and different priorties, can be extremely challenging. Learning these things about each other (especially in this kind of high intensity environment) will cause arguments and storms, but this is exactly why it's so useful. These differences which cause people to disagree and dispute are what allow us to look at challenges with a much wider scope, to see new angles on things we might not understand and to find the best approach to a problem. Of course I am nervous to throw myself headfirst into the arms of a dozen strangers, but all friends were once strangers.

Roberto’s mistakes hand Burnley 3-0 win over West Ham
by The Associated PressBURNLEY, England (AP) — Mistakes from West Ham goalkeeper Roberto handed Burnley a 3-0 win in the Premier League to end a losing run on Saturday.
Ashley Barnes scored in the 11th minute after Roberto failed to catch the ball at a corner.
Chris Wood put the ball in the net, only for video review to disallow it for offside, but scored soon after in the 44th after a poor pass in defense left West Ham exposed.
West Ham’s inconsistent stand-in for the injured Lukasz Fabianski, Roberto added an own-goal in the 54th, knocking the ball into his net at a corner.
After three straight losses, the win at Turf Moor returns Burnley to the top half of the table, while West Ham is on a seven-game run without a win in all competitions since beating Manchester United 2-0 on Sept. 22. The Hammers haven’t won away in the league since August.
There was another blow for West Ham in stoppage time as Manuel Lanzini was stretchered off with an apparent shoulder injury.

Mum praises teacher's great idea to end parents' Christmas present buying pressure
Steff Ravenhall's daughter returned from St Patrick's Roman Catholic Voluntary Aided School with a letter from her teacher that suggested a king-hearted alternative to Christmas gifts
by Hannah GrahamParents used to the pressure of finding the perfect gift for their children's teacher have praised her for requesting they do something "heart warming" instead.
Last week Steff Ravenhall's daughter Harriet Warring, 7, came home with a letter from her teacher Mrs Gardner.
Preempting the mountains of chocolates and red wines that would come her way, the teacher thanked parents for their "kind generosity" of Christmases gone by but asked that it be redirected this year, Chronicle Live reported.
"I would like to reduce your stress a little and ask that you don't buy me a gift," she wrote.
"I thoroughly enjoy teaching your children and my job is a pleasure to do."
This was no present ban however.
The deputy head and year two teacher urged parents at the St Patrick's Roman Catholic Voluntary Aided School in Dipton, County Durham to send an anonymous donation of no more than £2 to help those in need.
The request had a educational edge as well.
She said: "This half term we will be focusing on money in maths and the real meaning of Christmas in our RE lessons.
"With this in mind I would like the children to be involved in the social responsibility of giving and and kindness and plan to support a local family."
Once the envelopes had been received, the children would count up the cash inside and use it to buy an item from a local shop.
Steff, 26, was so impressed by the idea she shared a photo of the letter on Facebook in the hope of encouraging other schools to follow suit.
The mum said: "I just thought it was really heart-warming, and it obviously takes the pressure off, because you do worry about getting the teachers presents at this time of year.
"My daughter has been to a few different schools and it's always a topic of conversation for the parents, who is getting something, who is not going to bother, how much they're spending. Everyone just wants to get it right.
"The bit that got me the most was the fact that it was going to a local family. It's an important age, in year two, to be learning about the value of money, which is a really important lesson as well. And it teaches them that it's not just about receiving, it's about giving back.
"I've never seen another school do anything like this, lots of teachers will say to you 'oh, don't bother', but actually getting a letter saying 'here's what you can do instead' and there's a lesson kids are learning at the same time, that's what's really good about it."
The mum says she's already received messages online from teachers hoping to share the idea, and Steff's post has been shared hundreds of times on Facebook.
One woman commented: "This is an amazing idea and I wish other schools would do this!"
And another said: "This is a wonderful idea! Well done that teacher."

The link importing function of LinkX allows you to quickly add many links to the database. This document will provide an overview of the link importing process.
Import Data Format
To import links you will need to either place them in a text file or paste them into a text box in the link importing interface. In either case, the format needs to be the same. There should be only one link per line. Each line should have pipe (|) delimited data, with each field representing one piece of information about the link. The pieces may be in any order, but that order must remain the same throughout all of the links. For example:
user1@email.com|http://www.site1.com/index.html|Site #1 Title|Description of site #1|Roger user2@email.com|http://www.site2.com/main.html|Site #2 Title|Description of site #2|James user3@email.com|http://www.site3.com/index.php|Site #3 Title|Description of site #3|SusanThe above example has three links each with an e-mail address, site URL, site title, description, and submitter name. Once you have your links in the proper format, you can begin the importing process.
Control Panel Interface
To use the link importing feature access the Links > Import Links function from the control panel menu. This will load a page where you will be able to tell the software if you want to import from a file that you uploaded or if you want to paste your link data into the supplied text box. Each option is explained on the link importing interface. You will need to press the Analyze Input button if you have pasted data into the text box or the Analyze File button if you are importing from an uploaded text file.
After you press the correct Analyze button you will be taken to a page where you will see the first link split out into it's individual fields. On the left hand site of the Import Data section you will see drop down menus. From these menus you will need to select what each field represents. If one of the pieces of data for the link does not fit into any of the drop down menu options, select the IGNORE option. LinkX will ignore all the IGNORE fields when importing the links.
In addition to assigning each of the fields from the data you are importing, there are three additional items that you will need to setup. Each of those items are described below.

Select at least one category for the links to be placed in. This uses the Category Selector interfrace.
If you have included the category information in the import data, you do not need to select a category here
|
| Status | Select the status to assign to the imported links or 'From Import Data' if you have included the status in the import data. |
| Type | Select the type to assign to the imported links or 'From Import Data' if you have included the type in the import data. If you select Premium or Featured, enter an expiration date in the text input box following the drop down selection field. |
Including Categories in the Import Data
As of version 1.1.0 you can include categories directly in the import data rather than selecting the categories that the links will be imported into. This will allow you to import links into many different categories at once instead of having to import individually for each category. When including the categories in the import data, there are a few rules that you will need to follow:
For this example, assume that you have the following categories defined:
| Category | mod_rewrite URL |
| Algorithms | http://www.yoursite.com/algorithms/ |
| Algorithms / Sorting and Searching | http://www.yoursite.com/algorithms/sorting-and-searching/ |
| Algorithms / Compression | http://www.yoursite.com/algorithms/compression/ |
| Programming | http://www.yoursite.com/programming/ |
| Programming / C++ | http://www.yoursite.com/programming/c-plus-plus/ |
| Programming / C++ / Sorting and Searching | http://www.yoursite.com/programming/c-plus-plus/sorting-and-searching/ |
- Categories must always be provided as their full path. You cannot simply provide the name of a sub-category in the import data.
- Category names and mod_rewrite URLs are case-sensitive, so the categories that you include in your import data much match exactly
with the information stored in the LinkX database.
- The full path can either be the path as it appears in your mod_rewrite URLs or the path as it appears in the Manage Categories interface.
For example, if you were importing a link into the "Algorithms / Sorting and Searching" category, your import data could look like this:
<EMAIL_ADDRESS>/ Sorting and Searching|http://www.site1.com/... Or like this:user1@email.com|algorithms/sorting-and-searching|http://www.site1.com/... - You can import links into multiple categories during the import by providing a list of every category separated by a double-colon (::)
For example, to import a link into both the "Algorithms / Compression" and "Programming / C++" categories, you would use this:
<EMAIL_ADDRESS>/ Compression::Programming / C++|http://www.site1.com/... Or this for the mod_rewrite URL format:user1@email.com|algorithms/compression::programming/c-plus-plus|http://www.site1.com/...
Field Formats
Some of the items that you may want to import have specific formats that must be met in order for the galleries to be imported correctly. Each of those is discussed below.
| Status | Possible values: unconfirmed, pending, active, or disabled |
| Type | Possible values: regular, premium, or featured |
| Expires | YYYY-MM-DD HH:MM:SS |
| Date Added | YYYY-MM-DD HH:MM:SS |
| Date Modified | YYYY-MM-DD HH:MM:SS |


Cicada (formerly Yazoo) originally aimed to be a neural network simulator, missed by a mile, and ended up as a scripting language instead. As a nod to the original mission, our tutorial will be a program that lets a user create and train artificial neural networks, which are algorithms based on models of we think neurons in our brains work that are widely used for fuzzy tasks such as pattern-recognition. The time-consuming processes of simulating and training the networks will be written in C, for speed. (This code is also C++ compatible.) We will then write Cicada wrappers so that these networks can be controlled at the Cicada command prompt. Finally, we will write (and debug) a script to use these networks to ‘learn’ words that the user types at the command prompt.

SOUL SURVIVORS A film review by Steve Rhodes Copyright 2001 Steve Rhodes RATING (0 TO ****): * 1/2
SOUL SURVIVORS, written and directed by Steve Carpenter, the writer of BLUE STREAK and the upcoming OCEAN'S ELEVEN remake, is a by-the-numbers horror movie whose only real scare comes from the sudden blast of a starter's pistol at a swim meet. The story is one of those in which it's never clear, until the end, who is alive and who is dead and what is a dream and what isn't. Even the ending explanation leaves plenty of plot holes to ponder. Well, it would if the movie weren't so instantly forgettable.
Melissa Sagemiller (GET OVER IT), Wes Bentley (AMERICAN BEAUTY), Eliza Dushku (BRING IT ON) and Casey Affleck (AMERICAN PIE 2) play young lovers Cassie, Matt, Annabel and Sean. Students at Middleton College in the town of Middleton, undoubtedly smack dab in the middle of America, the four kids form two love triangles. One night, when an ominous full moon gives way to a torrential downpour, the kids drive and argue along a slippery and twisting mountain road. Not looking properly, they careen into another car of kids, and one or more of them are killed. After that we have numerous flashbacks to the events surrounding the accident as well as imaginary sightings of dead people and lots of non-existent blood.
Along the way people say trite little things to encourage the survivors. As Father Jude, Luke Wilson comforts one by saying, "It's difficult to be a survivor, but it's up to God who lives and who dies."
About the only reason to see SOUL SURVIVORS is if you are desperate for a guilty pleasure. Carpenter tosses in a few erotic scenes, but ones that are in no danger of threatening his film's PG-13 rating. The most explicit of these has two girls taking a shower together. Don't worry. They stay fully clothed at all times.
Question number eight on one of the student's quizzes contains the phrase, "Abandon all hope ye who enter in." This would be good advice for those who decide to see this movie.
SOUL SURVIVORS runs 1:25. It is rated PG-13 for "terror/violence, sexuality and some substance abuse," and would be acceptable for kids around 12 and up.
The film opens in nationwide release today, Friday, September 7, 2001. In the Silicon Valley, it is showing at the AMC and the Century theaters.

{% import 'headers.html' as headers %} {% import 'footers.html' as footers %} {% import 'algo.html' as algo %}
This article will cover sieving technique and it's complexity, showing it's use in solving primes-related problems. To approach those problems, first certain definitions shall be formulated:
For each integer \(a \in \{1, 2 \dots n\}\) determine, whether it is a prime number. Constraint: \(n \le 10^6\).
This algorithm contains depictions of absolute brutality. One can check whether \(a\) is prime by checking whether any integer \(x \in \{ 2,3, \dots, a_i-1\}\) is it's divisor: if it is, then \(a\) is not a prime. Solution relying on applying for each integer in a range this technique works in \(O(n^2)\).
If an integer \(x\) is divisible by \(d\), then either \(d \le \sqrt{x}\), or \(\frac{x}{d} \le \sqrt{x}\) - and so, to check whether \(a\) is prime, one needs to check only integers in \(\{ 2, 3, \dots \lfloor \sqrt{a} \rfloor \}\) whether they divide \(a\). That makes the algorithm run in \(O(n \sqrt{n})\)
Let sequence \(SIEVE\) of length \(n\) denote, whether integer is considered a prime. At the start of the process, \(SIEVE=(1, 1, 1, \dots, 1)\) - everything is considered prime. Then, two things happen:
At the end of this process, every prime number will be marked (\(SIEVE_p = 1\)), and composite not-marked - because it is divisible by some prime.
{{ algo.neo_algorithm(1, 'Sieve', 'Input format: One integer \(n\) is the size of the sieve.
\(n\)
Begin starts the sieve with a given limit. Next move moves forward current sieve, Previous move moves backward. This sieve has 2 optimizations: first, if an integer is marked as non-prime, then all numbers it could mark were already marked by it's divisor. Proof:
$$ a|b \land b|c \implies \exists_{k, l \in N} (ka=b \land lb=lka=c) \implies a|c $$
Secondly, for given \(x\), no composite number \(y \lt x^2\) has lowest divisor \(d \gt 1\) greater or equal to \(x\), which was shown in 2nd solution to this problem - and so, marking can start from \(x^2\)
It can be easily proven, that sieve, even without any optimizations works in \(O(n*\log(n))\): In each operation, one either searches for next prime number: sum of all searches is just linear walk from the beginning to the end of table, so it's linear; or marks numbers. Marking numbers works in \(O(n*\log(n))\), because sum of reciprocals of \(n\) first integers can be estimated by \(O(\log(n))\): when sieve marks numbers divisible by \(2\), it passes at most \(\frac{n}{2}\) numbers; when it marks numbers divisible by \(3\), it passes at most \(\frac{n}{3}\) numbers, etc. So, algorithm works in:
$$
{% for i in [2, 3, 5, 7, 11, 13] %}
\frac{n}{ {{i}} }+
{% endfor %}
...+\frac{n}{maxPrime}
\le
{% for i in range(2, 8) %}
\frac{n}{ {{i}} }
+
{% endfor %}
...+\frac{n}{n} \le $$
$$ \le
{% for i in range(1, 4) %}
{% set s=jipow(2, i) %}
{% for j in range(s) %}
\frac{n}{ {{s}} }
{% if (j!=s-1) %}
+
{% endif %}
{% endfor %}
+
{% endfor %}
...+\frac{n}{2^{\lfloor log_2(n) \rfloor}} \le
$$
$$
\le
{% for i in range(1, 4) %}
{% set s=jipow(2, i) %}
{{s}}*\frac{n}{ {{s}} }+
{% endfor %}
...+2^{\lfloor log_2(n) \rfloor} * \frac{n}{2^{\lfloor log_2(n) \rfloor}} =
\sum^{\lfloor log_2(n) \rfloor}_{i=1} i*\frac{n}{i}=
n*\sum^{\lfloor log_2(n) \rfloor}_{i=1}1=
n \lfloor log_2(n) \rfloor=O(n*\log(n))
$$
Furthermore, the second inequality in this proof also shows, that sum of amount of divisors over all integers in a set \(\{1, 2, 3, \dots n\}\) can be estimated by \(O(n*\log(n))\) - because every divisor \(d\) has exactly \(\lfloor \frac{n}{d} \rfloor\) integers divisible by it, and sum \(\sum_{i=1}^{n} \frac{n}{i}\) can be estimated by \(O(n*\log(n))\).
Let's say You have to find a factorization all integers \(a \in \{2, 3, \dots, n\}\), where \(n \le 10^6\), i.e. find it's representation as product of prime numbers. For example, \(2852=2*2*23*31\). First question, that should be addressed before solving problem itself - is such factorization unique?
One can prove, that each number \(x \in N^+\) has unique factorization: if \(x\) is shown as \(x=p_1^{q_1}p_2^{q_2} \dots p_n^{q_n}\), where \(p_i \in P \land q_i \in N \land p_i \lt p_{i+1}\) (it is always possible to show \(x\) in such manner - this will also be proven) and also as \(x=r_1^{s_1}r_2^{s_2} \dots r_m^{s_m}\), where \(r_i \in P \land s_i \in N^+ \land r_i \lt r_{i+1}\), then \(m=n \land \forall_i (p_i=r_i \land s_i=q_i)\). It may be wise to prove certain lemmas first:
First simple solution for finding all primes dividing a number \(x\) (and how many times they divide \(x\)) consists of checking, whether \(x\) is divisible by subsequent numbers in range \(\lt 2;\lfloor \sqrt{x} \rfloor \gt\) and dividing \(x\) by all its found divisors as many times, as \(x\) is divisible by them. Formally, let \(x'_1=x\) and let \(x'_h\) denote value of \(x\) after dividing \(x'_h\) by \(h\) as many times, as \(x'_{h-1}\) was divisible by \(h\). Notice, that:
Input format: One number \(x\) to factorize.
\(x\)
Marking each number with it's lowest divisor (instead of sole information whether it's prime) leads to solving this problem in the same way as problem above, in complexity \(O(n \log n)\): below is an animation of inner workings of such sieve and query mechanism (which works only after finishing sieve)
\(lpf(x)\) denotes least prime factor of \(x\) - for example, \(lpf(45) = lpf(3^2*5) = 3\)
Input format: One number \(n\) is the maximal number, for which a minimal divisor has to be found:
\(n\)
Input format: One number \(v\) is the value to factorize
\(v\)
'
, 'start_value':'24', 'kvargos':{} }, 'Enchanced sieve with factorization') }}
Apparently, one can prove, that sum of reciprocals of primes up o \(n\) can be estimated by \(O(n \log \log n)\): $$ \sum_{p \in P \land p \le n} \frac{1}{p} = O(n \log \log n) $$ Hence, one can estimate complexity of a sieve by \(O(n \log \log n)\).
Suppose, that You are given two integers \(a,b\), and thine aim is to determine for each number in range \(\lt a; b \gt\) whether it is prime. \(1 \le a \le b \le 10^{12}, b-a \le 10^6\)
Let \(S=\{a, a+1, \dots, b-1, b\}\). Notice, that element of \(S\) is prime if and only if it has no prime divisor in range \(\lt 1; \sqrt{b} \gt\). The idea is thus as follows:
Complexity is same as in case of standard sieve, proof is also identical.
Sieves allow solving multitude of problems, including among others finding Euler totient function or applying inclusion/exclusion principle on divisors. Example problems regarding sieves from codeforces: Empire Strikes Back, Morrowindows, Winter is Here

Schema Diff¶
Schema Diff is a feature that allows you to compare objects between two databases or two schemas. Use the Tools menu to access Schema Diff.
The Schema Diff feature allows you to:
Compare and synchronize the database objects (from source to target).
Visualize the differences between database objects.
List the differences in SQL statement for target database objects.
Generate synchronization scripts.
Note:
The source and target database servers must be of the same major version.
If you compare two schemas then dependencies won’t be resolved.
Click on Schema Diff under the Tools menu to open a selection panel. To compare databases choose the source and target servers, and databases. To compare schemas choose the source and target servers, databases, and schemas. After selecting the objects, click on the Compare button.
You can open multiple copies of Schema Diff in individual tabs simultaneously. To close a copy of Schema Diff, click the X in the upper-right hand corner of the tab bar. You can rename the panel title by right-clicking and select the “Rename Panel” option.
Use the Preferences dialog to specify following:
Schema Diff should open in a new browser tab. Set Open in new browser tab option to true.
Schema Diff should ignore the whitespaces while comparing string objects. Set Ignore whitespaces option to true.
Schema Diff should ignore the owner while comparing objects. Set Ignore owner option to true.
The Schema Diff panel is divided into two panels; an Object Comparison panel and a DDL Comparison panel.
The Schema Diff Object Comparison Panel¶
In the object comparison panel, you can select the source and target servers of the same major version, and databases to be compared. You can select any server listed under the browser tree whether it is connected or disconnected. If you select a server that is not connected then it will prompt you for the password before using the server.
Next, select the databases that will be compared. The databases can be the same or different (and within the same server or from different servers).
After you select servers, and databases, click on the Compare button to obtain the Comparison Result.
Use the drop-down lists of Database Objects to view the DDL statements.
In the upper-right hand corner of the object comparison panel is a Filter option that you can use to filter the database objects based on the following comparison criteria:
Identical – If the object is found in both databases with the same SQL statement, then the comparison result is identical.
Different – If the object is found in both databases but have different SQL statements, then the comparison result is different.
Source Only – If the object is found in source database only and not in target database, then the comparison result is source only.
Target Only – If the object is found in target database only and not in source database, then the comparison result is target only.
Click on any of the database objects in the object comparison panel to display the DDL Statements of that object in the DDL Comparison panel.
Schema Diff DDL Comparison Panel¶
The DDL Comparison panel displays three columns:
The first column displays the DDL statement of the object from the source database.
The second column displays the DDL statement of the object from the target database.
The third column displays the difference in the SQL statement of the target database object.
You can review the DDL statements of all the database objects to check for the differences in the SQL statements.
Also, you can generate the SQL script of the differences found in the target database object based on the SQL statement of the source database object. To generate the script, select the checkboxes of the database objects in the object comparison panel and then click on the Generate Script button in the upper-right hand corner of the object comparison panel.
Select the database objects and click on the Generate Script button to open the Query Tool in a new tab, with the difference in the SQL statement displayed in the Query Editor.
If you have clicked on the database object to check the difference generated in the DDL Comparison Panel, and you have not selected the checkbox of the database object, pgAdmin will open the Query Tool in a new tab, with the differences in the SQL statements displayed in the Query Editor.
You can also use the Copy button to copy the difference generated in the DDL Comparison panel.
Apply the SQL Statement in the target database to synchronize the databases.
