[gecode-users] Crash while freeing memory in connection with VS2010

Hi once again,
the code below compiles and links in both versions (so I assume I did not make an all too obvious modeling mistake) but it crashes in VS2010 in contrast to VS2008(Express).
The error seems to occur during the destruction of the linear expression. The debugger sets the break point to Heap::rfree(void* p) in heap.hpp in all three cases.
Can you reproduce it?
Thanks for help,
Alexander

After defining destination address and NAV amount to deliver, SPUR provides an address and the full amount to transfer including the specified fee.
Send the full amount to the SPUR given address and your NAVS will be delivered using NAVTech nodes.
Why is it anonymous?
We believe that you are familiar with NAVTech if you arrived here, otherwise please take a deeper look to technical details on their White Paper: http://navcoin.org/downloads
SPUR sends the transactions through NAVTech anon servers, making impossible to link originator of the transaction to destinatary.
Both the amount and the destination of the transaction are encrypted using KBPGP javascript library on your browser before leaving your computer, so even a MITM attack or being spied by your government/ISP wouldn't compromise your anonimity.
To further improve anonymity, we decided to launch SPUR only as a hidden service on TOR.
Please double check that the address you are accessing is the right one: http://4su7pqq6nyaecqoo.onion
Could any of the involved addresses be tracked or linked to the transaction?
Every address is unique and generated for each transaction and will be only used one time.
Why do I receive the amount in several transactions on the destiny address?
Dividing the amount in different transactions and addresses makes impossible to link directly the transaction amount with the destiny, increasing the anonymity.
Why SPUR?
SPUR is a perfect solution to send anonymous NAV transactions from all type of wallets or systems.
Without the need to set up the required servers or full nodes, and adding the extra security layer of TOR.
Additional security measures
In order to remove even the most minimal possibility of transfers tracking, we automatically remove any collected data from our servers 12 hours after the transaction has been done.
What kind of data do you exactly store?
We hold a little -sqlite- database with the following fields:
- Address where you will send the coins.
- Encrypted destination address.
- Original value.
- Fee.
- Expected value.
- Amount of coins received.
As already stated, the transaction in the db will be cleaned 12 hours after being initiated.
What happens if I send a different amount?
If the sent amount is lower, the anon transaction will not be executed.
You will see the reached amount on the screen and you can do another transfer to fulfill the full amount.
Please be aware that if the remaining amount is not delivered before the transaction operation expires, the money will not be returned.
You have 6 hours to do it.
If the amount is higher, only the amount requested will be delivered to destination.
Please ensure to send the exact amount.
What if I have a problem?
As we don't keep track of any transaction data and due to the ninja nature of NavTech, we won't be able to identify you and probably will be impossible to help you if anything goes wrong once the NAVCoins leave our servers.
If you think your coins are stuck on our servers, please contact us.


Executive with resort background takes helm of SeaWorld
ORLANDO, Fla. (AP) - An executive from the timeshare and resort industries is taking over as CEO of SeaWorld Entertainment.
The Orlando-based theme park company on Thursday said Sergio Rivera will be the next chief executive, and he’ll join the company’s board, starting next week.
He succeeds Gustavo “Gus” Antorcha, who stepped down in September, just months into his tenure as chief executive. Antorcha said in a resignation statement that he had a different approach than the board.
Rivera previously served as the president and CEO of ILG, Inc.’s vacation ownership segment.
Before that, Rivera worked for Starwood Hotels & Resorts Worldwide, where he was president of the Americas division.
The company also said Neha Jogani Narang will join the board.

CRWA's Flagging Program uses a system of color-coded flags to indicate whether or not the river's water quality is safe for boating at eleven boating locations between Watertown and Boston. Flag colors are based on E. coli and cyanobacteria (blue-green algae) levels:
CRWA estimates E. coli bacteria levels using models that take into account a variety of environmental factors including rainfall and river flow. CRWA collects water samples weekly to verify the model forecasts. Cyanobacteria monitoring is conducted every 1-2 weeks.
Note that the predictions are based only on the CRWA's predictive modeling of E. coli levels. Please see the CRWA's website for official flag determinations that incorporate CSO monitoring and cyanobacteria monitoring.

Pmw.RadioSelect() - a set of buttons, some of which may be selected
A radio select is a container megawidget which manages a number of buttons. The buttons may be laid out either horizontally or vertically. In single selection mode, only one button may be selected at any one time. In multiple selection mode, several buttons may be selected at the same time and clicking on a selected button will deselect it.
The buttons displayed can be either standard buttons, radio buttons or check buttons. When selected, standard buttons are displayed sunken and radio and check buttons are displayed with the appropriate indicator color and relief.
add()
method. If 'button', the default type is Tkinter.Button. If
'radiobutton', the default type is Tkinter.Radiobutton. If
'checkbutton', the default type is Tkinter.Checkbutton.
If 'radiobutton', single selection mode is automatically set. If 'checkbutton', multiple selection mode is automatically set. The default is 'button'.
invoke()
is called.
In single selection mode, the function is called with a single argument, which is the name of the selected button.
In multiple selection mode, the function is called with the first argument being the name of the button and the second argument being true if the button is now selected or false if it is now deselected. The default is None.
If None, a label component is not created. The default is None.
add()
method. If
there is no label component, then no frame component is
created and the hull component acts as the container. By default, this component is a Tkinter.Frame.
Button components are created dynamically by the add()
method. The default type of the buttons depends on the value
of the buttontype option.
Button components are created with a component group of Button.
index()
method.
getvalue()
method.
In multiple selection mode, return a list of the names of the currently selected buttons.
index()
method. The value returned by command is returned.
In single selection mode, select only the button specified by the string textOrList.
In multiple selection mode, select only the buttons specified by the list textOrList.

Ever wanted to have lobster and cocktails on a historic vessel permanently docked on the Hudson River? Look no further than the Frying Pan. This unusual bar setting is perfect for afternoon cocktails on a lazy summer weekend.
Price: $$$
For a classy rooftop bar with an insane view of the New York skyline check out 230 Fifth bar. With an extensive cocktail list and many bar snacks to choose from this place is a favourite for after work drinks.
Price: $$
For a classic dive bar atmosphere reminiscent of a college frat party this is a great bar for the 20 something tourist wanting to mingle with post-college Americans. Whether its beer pong or taking in one of the classic American sports games this place will surely make for a forgettable night :P

4DPop AppMaker is an helper tool for the generation of application and / or component. It allows, after setting, with just one click, generate your application or your component and perform a number of tedious, repetitive tasks.
| 1. | Create a folder "Components" beside the structure file of your database (".4db") |
| 2. | Place the folder "4DPop AppMAker.4dbase"* or an alias of the folder into the "Components" folder |
| 3. | Open your database. |
| 4. | If the componant 4DPop is installed a new button "AppMaker" will appear in the tool bar. |
*On Macintosh, the component is a package with a ".4dbase" extension and could not be visible depending on your display settings.
Click on the button "AppMaker" in the 4DPop's palette will start the compilation and generation of the current database taking into account the parameters defined in the current project (the file ~/myBase.4dbase/Preference/BuildApp/BuildApp.xml).
If this shortcut is already appreciable, the component also automates the tasks we have to repeat before and after each release.
You can access to parameters of "4DPop AppMaker" through the menu associated with the 4DPop palette's button (displayed by clicking on the arrow or with a long click). The menu offers two choices:
• The first page allow to start the generation when the settings were changed. Just click the big button, the action is equivalent to a single click on the button of the pallet. |
|
| • The second page allows you to fill the XML keys of the current file BuildApp.XML.
(~/myBase.4dbase/Preference/BuildApp/BuildApp.xml)
For each XML key listed on the left, the description is presented in the upper right part with an indication of the relevant platform(s) as icons . If the parameter has a meaning for the current platform, it is possible to change its value in the lower right panel. If the key is not relevant for the current platform, the data are displayed but not editable. A padlock symbol is displayed into the help area. The XML keys are underlined if there is data.

• The page "Preparations" allow to enter the name of a method of your database that will be run before compilation and generation. This method must return True if the generation process can continue. If the method returns False, the generation is canceled. Remember to declare your method "Shared between components and host database". The key/value pairs listed in the table allow you enter information which will be included in the file infoplist.strings (generated in all the language folders). On Macintosh, this file is used with the info.plist file in the root of the package. These two files allow to display the informations about the package. |
|
| • The page "Finishes" is used to specify files/folders to be copied or to be removed from the package after generation. The default generation done by 4D copies the file "mabase.4DC" and the folder "resources" but ignores some useful files. So we must integrate files by hand like the file "mabase.htm" for the help file or the folder "Macros v2" for exemble. Similarly the folder "resources" is entirety copied. You may want to delete from the released version the files or folders that only concerns the development stage.
You can also, on this page, enter the name of a method of your database to be launched at the end of the process. Again, remember to check"Shared between components and host database" |
|
• The last page is for setting some options:
|
Several methods are shared by the component.
These are utilities or entry points to be used by your database (principaly in the methods that are executed before and after generation if any).
These methods will be documented later. Here's a list:
Note: It is best to call these methods with the command EXECUTE METHOD in order to allow remove the component 4DPop AppMaker from your distributed database.
This component is provided in compiled version but you can find the source code in the "SOURCES" folder that is located inside the component folder.

 I had no idea what it was, but I knew I wanted to make something with it.
cutting boards are made by cutting a solid piece of wood into narrower strips, turning each of those strips up on their ends, and joining them together. This allows the inner grain to be displayed, and creates the elegant symmetry. Additionally, it helps provide a harder cutting surface that lasts much longer.
After everything was joined and shaped, the board took a few turns through the drum sander to remove any remaining wood glue runout and minimal surface deviance. I finished with several passes of hand sanding with a fine grit. I researched various sealing and finishing options and ended up choosing a mix of beeswax and mineral oil that gave the board a nice rich gold finish. I applied 4 coats to the board and let it rest for 24 hours before its initial use. I had to reapply the finish after a few days of use, but the second application has held up much more as it has permeated the wood.

Installation¶
PyVISA is a frontend to the VISA library. It runs on Python 2.7 and 3.4+.
You can install it using pip:
$ pip install -U pyvisa
Backend¶
In order for PyVISA to work, you need to have a suitable backend. PyVISA includes a backend that wraps the National Instruments’s VISA library. However, you need to download and install the library yourself (See NI-VISA Installation). There are multiple VISA implementations from different vendors. PyVISA is tested only against National Instruments’s VISA.
Warning
PyVISA works with 32- and 64- bit Python and can deal with 32- and 64-bit VISA libraries without any extra configuration. What PyVISA cannot do is open a 32-bit VISA library while running in 64-bit Python (or the other way around).
You need to make sure that the Python and VISA library have the same bitness
Alternatively, you can install PyVISA-Py which is a pure Python implementation of the VISA standard. You can install it using pip:
$ pip install -U pyvisa-py
Note
At the moment, PyVISA-Py implements only a limited subset of the VISA standard and does not support all protocols on all bus systems. Please refer to its documentation for more details.
Testing your installation¶
That’s all! You can check that PyVISA is correctly installed by starting up python, and creating a ResourceManager:
>>> import pyvisa
>>> rm = pyvisa.ResourceManager()
>>> print(rm.list_resources())
If you encounter any problem, take a look at the Miscellaneous questions. There you will find the solutions to common problem as well as useful debugging techniques. If everything fails, feel free to open an issue in our issue tracker
Using the development version¶
You can install the latest development version (at your own risk) directly form GitHub:
$ pip install -U https://github.com/pyvisa/pyvisa/zipball/master
Note
If you have an old system installation of Python and you don’t want to mess with it, you can try Anaconda. It is a free Python distribution by Continuum Analytics that includes many scientific packages.


import
statements.
Regular import
statements are unnecessary when not using imported classes and packages in the source file.
The same applies to imported static
fields and methods that aren't used in the source file.
Example:
import java.util.ArrayList;
public class Example {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
After the quick fix is applied:
public class Example {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}

To address a potential issue of damaging the intrinsic data discrimination by explicitly learning domain-aligned features, we propose a source-regularized, deep discriminative clustering method in order to directly uncover the intrinsic discrimination among target data, termed as Structurally Regularized Deep Clustering (SRDC). In SRDC, we also design useful ingredients to enhance target discrimination with clustering of intermediate network features, and to enhance structural regularization with soft selection of less divergent source examples. |
|
Unsupervised domain adaptation (UDA) is to make predictions for unlabeled data on a target domain, given labeled data on a source domain whose distribution shifts from the target one. Mainstream UDA methods learn aligned features between the two domains, such that a classifier trained on the source features can be readily applied to the target ones. However, such a transferring strategy has a potential risk of damaging the intrinsic discrimination of target data. To alleviate this risk, we are motivated by the assumption of structural domain similarity, and propose to directly uncover the intrinsic target discrimination via discriminative clustering of target data. We constrain the clustering solutions using structural source regularization that hinges on our assumed structural domain similarity. Technically, we use a flexible framework of deep network based discriminative clustering that minimizes the KL divergence between predictive label distribution of the network and an introduced auxiliary one; replacing the auxiliary distribution with that formed by ground-truth labels of source data implements the structural source regularization via a simple strategy of joint network training. We term our proposed method as Structurally Regularized Deep Clustering (SRDC), where we also enhance target discrimination with clustering of intermediate network features, and enhance structural regularization with soft selection of less divergent source examples. Careful ablation studies show the efficacy of our proposed SRDC. Notably, with no explicit domain alignment, SRDC outperforms all existing methods on three UDA benchmarks. |
|
|
|
The success of deep learning relies on a large amount of training data. However, collecting and annotating data for all domains and tasks is extremely expensive and time-consuming. We can utilize data from a label-rich source domain to solve the task on a label-scarce target domain. But there is a distribution discrepancy between the source and target data. So the model trained on source data cannot be readily applied to target data. How to address this issue? Unsupervised domain adaptation (UDA)! |
|
|
|
(a) Illustration of the assumption of structural domain similarity, including two concepts: domain-wise discrimination and class-wise closeness.
The orange line denotes the classifier trained on the labeled source data and the green one denotes the classifier trained on the labeled target data, i.e. the oracle target classifier.
(b) Illustration of damaging intrinsic structures of data discrimination on the target domain by the existing transferring strategy.
The dashed line denotes the source classifier adapting to the damaged discrimination of target data, which has a sub-optimal generalization.
(c) Illustration of our proposed uncovering strategy. Discriminative target clustering with structural source regularization uncovers intrinsic target discrimination.
|
|
We propose to use deep discriminative target clustering in the output space and feature space at the same time. This is a new dual clustering framework.
The clustering algorithm obtains pseudo labels of target data to supervise the model training by minimizing an objective of two terms.
The first term is the KL divergence between the network prediction label distribution and the introduced auxiliary distribution;
the second term is a regularization of cluster size balance.
|
|
Based on the structural similarity between the source and target domains indicated by the UDA assumption,
we propose the structural source regularization — replacing the auxiliary distribution with truth label distribution,
and using the labeled source data to train the same classifier network layers, namely joint network training.
|
|
R1: Ablation Study In the following table, we can observe that when any one of our designed components is removed, the performance degrades, verifying that (1) both feature discrimination and structural source regularization are effective for improving target clustering; (2) the proposed soft source sample selection scheme leads to better regularization. |
|
R2: Source Refinement In the following figure, we can observe that the source images with a canonical viewpoint have the higher weights than those with top-down, bottom-up, and side viewpoints, which is intuitive since all target images are shown only from a canonical viewpoint. The observation affirms the rationality of our proposed soft source sample selection scheme. The images on the left are randomly sampled from the target domain Amazon and those on the right are the top-ranked (the 3rd column) and bottom-ranked (the 4th column) samples from the source domain Webcam for three classes. Note that the red numbers are the computed source weights. |
|
R3: Comparison under Inductive UDA Setting In the following table, we can see that our proposed uncovering strategy SRDC achieves closer results to Oracle Model, verifying the motivation of this work and the efficacy of our proposed SRDC. |
|
R4: Feature Visualization In the following figure, We can qualitatively observe that compared to Source Model, the target domain features can be much better discriminated by SRDC, which is based on data clustering to uncover the discriminative data structures. The t-SNE visualization of embedded features on the target domain. |
|
R5: Confusion Matrix In the following figure, we can observe quantitative improvements from Source Model to SRDC, further confirming the advantages of SRDC. The confusion matrix on the target domain. |
|
R6: Convergence Performance In the following figure, We can observe that SRDC enjoys faster and smoother convergence performance than Source Model. |
|
Notably, with no explicit domain alignment, our proposed SRDC outperforms all existing methods on three UDA benchmark datasets. Results (%) on Office-31 (ResNet-50). Results (%) on ImageCLEF-DA (ResNet-50). Results (%) on Office-Home (ResNet-50). |

HACKERS A film review by Joe Clark Copyright 1996 Joe Clark
You mustn't think Hackers is a craven movie-studio attempt to cash in on the perceived popularity of la vie online. In fact, the word "Internet" comes up only once in the film's 105 minutes, and is uttered hammily at that. No, the film makes an honest attempt to view the komputer-kid subculture as a group of actual kids who dig computers, as opposed to geeks without life or love. And as in the computer biz itself, Hackers is remarkably generous about who can jack in.
Included in Hackers' fin-de-siecle family is Phantom Phreak (real name Ramon, played by Renoly Santiago), a Latino dude with hair like Molly Johnson who befriends the new kid in town, Dade Murphy (Jonnny Lee Miller). You don't need a rap sheet as long as your arm to be a somebody in the hacker circuit, and Dade's shutdown of 1,507 computers in a single day (at age 11!) means his reputation precedes him as he settles into a surprisingly shipshape New York high school. He's a godlike figure, one on an inevitable course toward union with the only grrrl hacker around, Kate Libby (Angelina Jolie).
Funny thing is, Phantom Phreak seems about as attached to heterosexuality as his handle is to the letter F. As usual, he's not explicitly queer, but he's certainly not explicitly straight. (This is 1995, and kids today are much less hung up about that gender shit.) All that matters is ability, and the rainbow cast has that in abundance. Even the lads with genuinely geeky tendencies have their day.
Hackers' plot-- about an evil hacker with a lot of corporate toys to play with who attempts to frame our hero and his posse for an act of ecological destruction-- strains credulity as much as the hopelessly inaccurate images displayed on various computer screens. Director Iain Softley is more interested in playing with surfaces and emphasizing the fluidity of identity and character in the online realm.
The way Phantom Phreak tags along with-- and nurtures-- Dade and Kate conjures memories of doting Sal Mineo in Rebel Without a Cause. Razor and Blade, two Japanese phone phreaks-cum-pirate-TV operators, cross-dress via smart men's clothes and more make-up than a geisha but suffer no hit to their street cred at all. There's a standing joke about wearing a dress, and indeed, the souped-up paramilitary costumes are another exemplar of the surfacing of fetish gear in pop culture. Watch Kate's dream sequence for the most heterosexually queer 60 seconds of the year. And look closely at Jonnny Lee Miller as he stares at his laptop; it's onto his face that Softley reflects some implausible but beautiful fractal-like graphics. Miller's moles and scratches and five-o'clock shadow and gloriously mismatched hair and eyebrow colours are a living canvas of their own.
 The respectful, even-handed treatment of a wide-open culture that old farts will never understand is what gives Hackers its currency. Here's hoping for a sequel, in which Ramon's sex life becomes rather less phantom and rather more phreaky.
The face as digital canvas
Experimental design can pop up in the unlikeliest places, as Iain Softley's 1995 film Hackers will attest. Art direction and set decoration and production design are old hat in feature films, but Softley's corny youth-oriented computer caper is that rarest of things, a motion picture featuring actual graphic design.
That only makes sense, seeing as how virtually every character in the flick has his or her eyes glued to a computer screen half the time. Fading '80s wunderkind [2]Neville Brody designed the various computer screens visible in the film, all of which vary in implausibility from modest to hopeless. (Though millions of moviegoers use computers, Hollywood hasn't figured out how to represent them realistically, even in computer-centric movies.) Softley uses a few obvious filmic techniques that show off the movie's graphic design: Unabashedly fake mattes, like the face of hero Dade Murphy (Jonny Lee Miller) superimposed on and dissolving into a "data soup" of swirling mathematical equations, fractals, helices, and amoebas; quick intercut images meant to link the virtual with the real, like an overhead view of New York City that morphs into a salmon- and teal-hued circuit board; a City of Text that models data as a forest of glowing skyscrapers.
However, the big graphic surprise is Softley's innovative second-order device of simply reflecting computer screens onto the actors' faces. We see big fractal blobs ringed by diffuse wiggling flames; snippets of blank photographic film, sprocket holes and all; sawtooth edges as though cut by pinking shears; Roy Lichtenstein-style patterns of dots. Nowhere are these projections more winsome than on Miller's face, where they mix with his moles and scratches and five-o'clock shadow and gloriously mismatched dyed hair and natural eyebrow colours to form a living canvas.
Despite its threadbare storyline, Hackers is a must-see as one view of a future in which graphics are quite literally a reflection of computers and popular culture and aren't restricted to the high-class gulag of coffee-table art books.

Contains a dynamic array implementation.
Any given dynamic array dynArr
should be treated as if there was a constant associated with it of type size_t
and value S, the size of one of its elements. Many functions declared in this file have a final parameter called elemSize
, of type size_t
. For every call to one of these functions that acts on dynArr
, elemSize
should be set to S. In short, the size of an element of a given dynamic array should be treated as if it was constant.
The following invariants should be adhered to:
ctls_DynArray::data
must be either NULL
or dynamically allocated.ctls_DynArray::data != NULL
:ctls_DynArray::capacity
must not be zero.ctls_DynArray::size
must not be greater than ctls_DynArray::capacity
.ctls_DynArray::data
points to must be exactly ctls_DynArray::capacity * S
bytes wide.ctls_DynArray::data
must point to the first element of dynArr
, and dynArr
's elements must be contiguous.As long as these invariants are adhered to, the user should feel free to modify a dynamic array's fields directly if he has good reason to. For example, this file does not contain a pop
function, but the same effect can be achieved by simply decrementing ctls_DynArray::size
.
A dynamic array's elements can be accessed via ctls_DynArray::data
.
Though a given dynamic array's elements are often all of the same type, there is no reason why they cannot be of different types, as long as each type has the same size.
FE_INEXACT
may be raised during a call to ctls_dyn_append()
, ctls_dyn_insert()
, or ctls_dyn_extend()
.
| bool ctls_dyn_append | ( | struct ctls_DynArray *restrict | dynArr, |
| const void *restrict | elem, | ||
| size_t | elemSize | ||

| dynArr | pointer to an initialized dynamic array |
| elem | pointer to the element that is to be added |
| elemSize | size of one of dynArr 's elements |
true
if operation succeeds, false
if notIntended as a substitute for adding an r-value of dynArr
's "type" to the end, as this is impossible with void pointers. Note that dynArr
and elem
are restrict
, and therefore the object elem
points to cannot already be contained in dynArr
.
| struct ctls_DynArray* ctls_dyn_copy | ( | struct ctls_DynArray *restrict | dest, |
| const struct ctls_DynArray *restrict | src, | ||
| size_t | elemSize | ||
| ) |
Copies the contents of one dynamic array into another.
| dest | pointer to the destination dynamic array; must be either initialized, zeroed out, or NULL |
| src | pointer to the source dynamic array |
| elemSize | the size of one of src 's elements |

if dest
was not NULL
. Otherwise, it points to a dynamically allocated dynamic array. On failure, returns NULL
.If the operation succeeds, the dynamic array accessible via the returned pointer has the same size, capacity, and element size as src
.
This is only a convenience function. Making a copy of a dynamic array can be performed manually, if desired. This should be done if, for instance, src
's elements are aggregates and must be deep copied.

Review: The Siege
Starring: Denzel Washington Annette Bening Bruce Willis???
Directed by: Edward Zwick
Reviewed by: Joy Wyse
The Siege is one of those movies that should have been better than it is. The concept is very good, but a very weak script keeps it from fulfilling its potential. Also, the casting of the `Stars' greatly affects the plot. To say that the movie stars Bruce Willis is a joke. He appears in exactly 18 scenes, briefly in an opening sequence, and then he doesn't appear again until the second half is well underway. When he does appear, he almost seems to be laughing at the audience, realizing how insignificant his role is. It is one of those roles usually played by a character actor.
The biggest problem seems to be that Hollywood simply doesn't want to make a woman the star of a film like this. If the story had been told from Annette Bening's point of view, it could have been a superior movie. As it is, the viewer is totally confused, even after it's explained. There is no way that I can spoil the ending by revealing what transpires. If anything, it will help you understand what you are seeing. We all know that our government isn't perfect, but we hope that it's better than any other country's way of life. We also know that the FBI, the CIA, the police, the Army, etc. don't tell each other what is happening, and each wants credit for anything good that occurs, but none of them want to take the blame.
The true question asked by The Siege is: What happens when a country such as the United States of America assists a government against their oppressors and then, suddenly withdraws that support? It also makes us take a serious look at constitutional law. As Americans we often take our rights for granted. If you can sift through the sieve [rather the siege] you will find a moral.
There has been a lot of press about ethnic groups who object to the way they are portrayed in the film. I don't think that they have seen the film yet because, it shows how ALL ethnic groups band together here in the USA when a wrong is being done. It is so reminiscent of what happened to the Orientals in California following the bombing of Pearl Harbor.
I do not want to see this movie again, although I might watch it on TV some night just to try to see if it makes sense to me now. I give it a C-.

About HSI
Hyperspectral imagery (HSI) records continuous spectrum information for each object pixel instead of a monochrome or color intensities. These spectrum information gives very detailed information about the material constitution of the imaged object and increases the inter-subject discrimination. Follwing figure shows an example of HSIs in material identification. As can be seen, though it is black in pixel 1 and pixel 2, their spectral reflectances are different especially from 571nm to 638nm.
About MHT
Material based Hyperspectral Tracking (MHT) aims to utilize hyperspectral imagery (HSI) to boost visual object tracking. This is the first large scale hyperspectral tracking dataset including 35 color sequences and 35 hyperspectral sequence. We carefully collect videos to include multiple target categories, diverse scenarios, rich activities and diverse content, etc.,to guarantee the generality and complexity of dataset. We believe this benchmark can not only complement the lack of investigating HSIs for object tracking but also drive the potential usability of HSIs in other computer vision problems, for example semantic segmentation and object detection.
MHT Benchmark
For each video in the dataset, we label the ground-truth by proving the bounding box annotation in the form of [x, y, width, height]
. Each video is also labeled with the challenging factors according to 11 attributes listed in~\cite{Wu2015}, including illumination variation (IV), scale variation (SV), occlusion (OCC), deformation (DEF), motion blur (MB), fast motion (FM), in-plane rotation (IPR), out-of-plane rotation (OPR), out-of-view, (OV), background clutters (BC), low resolution (LR). An overvirew of the dataset is shown as below. The full dataset can be downloaded on via Googledrive
Citation
@InProceedings{Xiong_2019_CVPR, author = {Fengchao Xiong, Jun Zhou, Kun Qian, Yuntao Qian}, title = {Spectral-spatial features for material based object tracking in hyperspectral video}, booktitle = {The IEEE Conference on Computer Vision and Pattern Recognition (CVPR)}, month = {June}, year = {2019} }
Evaluation
The same as OTB dataset, we conduct one-pass evaluation (OPE) to assess the performance of each tracker. Three evaluation metrics are adopted, namely, distance precision, overlap precision and area under curve of sucess plot to measure different tracking algorithms. The definitions of the three metrics can be seen in the paper.


Introducing Filters and Services
In this chapter, we will add two features to our app. First, we will get the recipe data from a service instead of hardcoding mock data into the app. Second, we will look at another handy tool in Angular’s toolbox - filters. When you’re finished, you will be able to use built in filters as well as create your own custom filters. You will also be able to read data from a server-side service like a real app.
The code
Here is the code for the next version of our Recipe Book app. Run the code in Dart Editor. Notice the text box and checkboxes at the top of the app. You can use these inputs to control which recipes are shown in the list. Start typing into the filter box and watch the list of visible recipes shrink to match your search criteria. Next, limit your results further by checking a few categories to limit to. Try using both filters together by typing in a search criteria and also limiting based on category. Lastly, clear the filters by pressing the “Clear Filters” button, and watch all your results re-appear.
Introducing filters
Filters let you change how your model data is displayed in the view without changing the model data itself. They do things like allow you to show parts of the model data, or display data in a particular format. You can also use Angular’s custom filters feature to create your own filters to do anything you want.
Built in filters
Angular has some built in filters that provide some handy functionality. Here is a list of all the currently implemented AngularDart filters
These are pretty self explanatory. The CurrencyFilter
formats numbers like money. The DateFilter
formats dates. The UppercaseFilter
and LowercaseFilters
do what you would expect. The LimitToFilter
limits the number of results for a list model object that will appear in the view.
In our app, we use the FilterFilter
. Like the LimitToFilter
, the FilterFilter
also limits the number of list model objects that will appear in the view. It chooses which items to display based on whether or not they satisfy the filter criteria.
Here is how we use the FilterFilter
.
First, we created a text input box and bound it through ng-model
to a property called nameFilterString
. As the user types into the text input box, it updates the model object’s nameFilterString
property.
<input id="name-filter" type="text" ng-model="ctrl.nameFilterString">
Next, we pipe the ng-repeat
criteria through the filter, and tell the filter to use ctrl.nameFilterString
as the property to check.

 ...

Lastly, we create a property on our RecipeBookController
to store the nameFilterString
property for the input.
String nameFilterString = "";
That’s all you need to start filtering your results.
Custom filters
Built in filters are nice, but what if you want to do something more specific. In our app, we also want to be able to reduce the number of recipes shown to those in a particular category. For this, we write a custom filter called CategoryFilter
.
A custom filter in Angular is simply a Dart class that declares a call
method with at least one argument:
call(valueToFilter, optArg1, ..., optArgN);
The first argument is the incoming model object to be filtered; in our case, it will be the recipe list. The remaining (0 or more) optional arguments (named optArgi
above) serve as input from the view, and they will be applied in some way to the valueToFilter
to perform the filtering. In our case, as will be explained below, we need only one optional parameter to let us weed out recipes from the incoming list that we don’t want to display.
The call
method should return the filtered value. In our case, it is a new recipe list that is a subset of the incoming recipe list.
Here is the call method from our CategoryFilter
:
call(recipeList, filterMap) { if (recipeList is List && filterMap is Map) { // If there is nothing checked, treat it as "everything is checked" bool nothingChecked = filterMap.values.every((isChecked) => !isChecked); if (nothingChecked) { return recipeList.toList(); } return recipeList.where((i) => filterMap[i.category] == true).toList(); } }
The filterMap
parameter deserves some further explanation. It’s the data that comes in off of the checkbox inputs. We will talk a little bit more about how checkboxes work in Angular in the next section.
Next, annotate the class to publish it as a filter:
@NgFilter(name: 'categoryfilter')
Add the new class to the bootstrapping code:
class MyAppModule extends Module { MyAppModule() { ... type(CategoryFilter) ... } }
and then use it from the view:

 Filter recipes by category  <input type="checkbox" ng-model="ctrl.categoryFilterMap[category]">{{category}}

Our view creates a checkbox input and label for each category. Angular stores each checkbox value as a boolean - true if checked, or false if not checked.
To create the checkboxes, we added a new piece of data to our app - a list of categories. We use the ng-repeat
Directive to iterate through the list and create a checkbox and label for each category. Inputs in Angular are bound to a model object with the ng-model
Directive. Here, we bind to a map called categoryFilterMap
. The map’s keys are the category names, and the values are true or false depending on whether or not they’re checked.
Next, we plug the custom filter in the same way we would plug in a built in filter:

Filter chaining
Our app uses a feature called filter chaining to apply more than one filter to the same view element. Below, we see the ng-repeat
Directive has three filters separated by pipes. This is how Angular applies multiple filters to a single ng-repeat
.

Introducing the Http
service
Our last example had the data hard coded in the app. In reality, you’d request data from a server side service. Angular provides a built in service called the Http
Service that handles making HTTP requests to the server. First lets look at the two new files we’ve added to the project: recipes.json and categories.json. These contain data that’s been serialized as a JSON string. We will use the Http
service to make an HTTP request to the web server to fetch this data. Let’s look at how to do this.
First, we declare a property on the RecipeBookController
class. Ours is called _http
. The Http
service is part of the core Angular package, so you don’t need to import anything new. Next, look at the RecipeBookController
’s constructor. We’ve added a parameter and assigned it to the _http
property. Angular instantiates the RecipeBookController
class using Dependency Injection. In the main method, you set up the injector with your app’s module where you included the code to construct a RecipeBookController
. The call to ngBootstrap
includes the AngularModule
, which contains injection rules for all of Angular’s core features, including the Http
service.
class RecipeBookController { Http _http; ... RecipeBookController(this._http) { _loadData(); } ... }
class MyAppModule extends Module { MyAppModule() { ... type(RecipeBookController); ... } } main() { ngBootstrap(module: new MyAppModule()); }
Next, let’s look at how to use the Http
service to fetch data from the server. Look at the changes we made to the _loadData
method. Here is the new code:
void _loadData() { recipesLoaded = false; ... _http.get('recipes.json') .then((HttpResponse response) { for (Map recipe in response.data) { recipes.add(new Recipe.fromJsonMap(recipe)); } recipesLoaded = true; }) .catchError((e) { recipesLoaded = false; message = ERROR_MESSAGE; }); ... }
Let’s look more closely at the call to the Http
service:
_http.get() .then((value) { // use value }) .catchError((e) { // handle error });
The Http
get
method returns a Dart Future. A Future is the promise of a value sometime in the future. It is at the core of asynchronous programming in Dart. In its simplest form, thethen()
method takes a single function argument. This function is invoked when the Future completes with a value (i.e., successfully), and is used to process the value returned from the Future. The catchError()
method also takes a function argument. This function will be invoked if an error is emitted by the Future.
The important thing to understand from this example is that Futures are asynchronous. Your app code will proceed while the data is loading from the server side. If you are connecting to a very slow service, it is possible that the app will finish loading before the data has been returned. The view should be prepared for this. In our case, we need two pieces of data before the app is useful:
List categories = []; List<Recipe> recipes = [];
Until the future has returned, your recipe book contains an empty list of recipes and an empty list of categories. Any part of your view that uses or displays recipes or categories will see an empty list. If you don’t want empty spots displaying on the app, you can surround portions of your view with statements that display a “Loading...” message until the data is ready.
In our app, we keep track of whether we have enough data to load the app by storing the load state for recipes and categories and conditionally displaying a load message, or the whole view, depending on whether the app is done loading enough data to be useful.

 {{ctrl.message}}

 ...

You can see the “Loading...” feature work by simulating a really slow loading data source. Put a breakpoint inside one of the then()
closures in the _loadData
method and load the app. Notice that while you’re stopped at the breakpoint, your app shows the “Loading...” message. Now get out of the breakpoint and notice that your app’s real view pops into place. Also notice that we changed the loaded state from false to true inside the asynchronous part of _loadData
(inside the then()
call’s argument). If we’d put it at the end of the _loadData
method outside of the asynchronous call, it would evaluate regardless of the state of the Future.
Angular features
ng-cloak
You probably noticed that in previous examples, when you first loaded your app, you briefly saw curly braces like {{someVar}}
before your app “popped” into place, and the correct values appeared. The ng-cloak
Directive combined with some CSS rules that you add to your app’s main CSS file allow you to avoid this blink. The blink happens between the time your HTML loads and Angular is bootstrapped and has compiled the DOM and has substituted in the real values for the uncompiled DOM values. While Angular is compiling the DOM, you can hide the page (or sections of it) by using ng-cloak
:
or
The CSS rule causes the view to be hidden:
[ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak { display: none !important; }
Once Angular is finished compiling the DOM, it secretly removes the ng-cloak
class or Directive from the DOM and allows your app to be visible.
Try it yourself
Now it’s your turn. Here are three ways in which you can extend the app version described in this chapter.
- Write a filter to convert degrees Fahrenheit (F) into degrees Celsius (C) in the recipe description. Round the resulting degrees Celsius to the nearest multiple of 5: e.g., 300 degrees F would become 150 C. (Hint: Dart has a
String
function namedcloak
that could be handy in this case.) - Write one or more filters (as necessary) to replace all the occurrences of “sugar” and “powdered sugar” by “maple syrup” both in the ingredients and the recipe description.
- Finally, pretend that you are cooking for a large party, and create a filter that will multiply all the amounts in the recipes. Hint: You’ll have to change the recipe model to include a more full featured “Ingredient” field that contains an amount, and then possibly a unit, and finally, an item name. Next, add a “multiplier” input that will allow the user to double, triple, or quadruple the recipe. Lastly, write a custom filter that multiplies each amount by the number specified in the multiplier input. Note: If your code fails with the error “5 $digest() iterations reached”, then read this explanation on StackOverflow. Also note the suggested workaround of piping ingredient values into a (custom)
toString
filter.

The adventure continues, as I persist in refactoring Net::SSH to take advantage of dependency injection, using Needle. This issue of the adventure will detail a snag in the refactoring, and some of my current thinking to overcome it.
I’m down to the last piece of the transport layer implementation. (For those that care, the transport layer is the lowest level of the SSH2 protocol, managing the sending and receiving of packets. This includes compression, encryption, and validation of packets.) This last piece is the Net::SSH::Transport::Session class.
The session is the piece that ties all the different parts of the transport layer together, sitting them all down at the table and making them work together. Specifically, the transport layer’s responsibilities include:
To accomplish these responsibilities, the session has dependencies on the following services:
outgoing_packet_stream
(for sending packets)incoming_packet_stream
(for receiving packets)kex_names
(for identifying the kex algorithm implementation to use)cipher_factories
(for returning cipher implementations appropriate for the selected cryptography backend)key_factories
(for returning key implementations)hmac_factories
(for returning hmac implementations)buffer_factories
(for returning buffer implementations)compression_algorithms
(for returning compression algorithm implementations)decompression_algorithms
(for returning decompression algorithm implementations)logs
(for obtaining a new logger reference)socket_factory
(for opening a network connection to the requested host/port)There may even be a few more, as I dig deeper into refactoring this beast.
The challenge is this: nearly every one of those services is needed in the session’s constructor. That means that injecting the dependencies as setters won’t work—they don’t get set soon enough. Every single one of these must be passed as an argument to the constructor.
Yech.
So, I’ve spent some time thinking about this. There are a few different ways to go about this.
The first option is to just do it the “academic” way. “The process recommends approach X, so I’ll do approach X.”
I don’t think anyone will blame me from balking at this. How many parameters does that mean the constructor takes? Eleven?!
transport.register( :session ) do |c,p| Net::SSH::Transport::Session.new( c.outgoing_packet_stream, c.incoming_packet_stream, c.kex_names, c.cipher_factories[c.crypto_backend], c.key_factories[c.crypto_backend], c.hmac_factories[c.crypto_backend], c.buffer_factories[c.crypto_backend], c.compression_algorithms, c.decompression_algorithms, c.logs.get(p.fullname), c.socket_factory ) end
No.
True, the burden of this could be mitigated somewhat by sending a hash to the constructor and injecting the parameters that way. That almost makes it look like setter injection, too:
transport.register( :session ) do |c,p| Net::SSH::Transport::Session.new( :outgoing_packet_stream => c.outgoing_packet_stream, :incoming_packet_stream => c.incoming_packet_stream, :kex_names => c.kex_names, :cipher_factory => c.cipher_factories[ c.crypto_backend ], ... ) end
A little better. I might at least consider such an approach. But there’s got to be a better way!
Constructor injection is fine-don’t get me wrong-but my personal preference is setter injection. When using constructor injection, it becomes hard to deal with many dependencies (as demonstrated above). Also, you can’t name the dependencies (unless you use a hash, which is too prone to typos).
So, another option I considered is to just use setter injection. The problem with this in this case, as I mentioned, is that the logic that needs the dependencies is in the constructor, which is called before the setters can be called.
The solution, then, is to put the construction logic that needs the dependencies in a separate method, which is invoked explicitly after the setters have been taken care of.
transport.register( :session ) do |c,p| session = Net::SSH::Transport::Session.new session.outgoing_packet_stream = c.outgoing_packet_stream session.incoming_packet_stream = c.incoming_packet_stream session.kex_names = c.kex_names session.cipher_factory = c.cipher_factories[ c.crypto_backend ] ... session.initialize_service end
I like this better, because I can use my beloved setter injection. However, having to invoke the “initialize_service” method explicitly feels a bit kludgy. It is also prone to error, since that step would be easy to forget. (Fortunately, it would only need to exist in a very few places in the code, so that’s not as big of a drawback as it could be, in this case.)
So the question that came to my mind was, “Should Needle handle this case?” Needle could, of course, be modified to check each newly instantiated service to see if it reponds to a special method name (like “initialize_service”), and if it does, invoke that method automatically. It could, but should it?
 This approach is, after all, supported by Copland and HiveMind. It works nicely in those frameworks. Upon reflection, though, I think it does not belong in Needle, and here’s why:
Copland and HiveMind try to be application frameworks. They try to do a lot of things, most of it magic, to make life easier for the developer. This makes those frameworks large and complex (which is not necessarily a bad thing).
The goal of Needle is to be a framework framework. That is to say, other frameworks may be built on top of Needle, adding complexity as needed. Needle itself should stay small, and relatively simple. This allows Needle to be fast as well, since the common case does not need (for example) to invoke an initialize_service
method and should not be slowed down by an unnecessary call to responds_to?
.
This means that developers using Needle directly may need to do a little more work (in some of the less common situations) than they would with other frameworks, like Copland. However, for most tasks, Needle will be at least as easy to use as those frameworks, and will scale much better, to boot.
If someone wanted to be able to add the automatic call to “initialize_service”, they could do it as a new service model. Or, as a new element in the instantiation pipeline, to use the terminology I described in Thoughts on Service Models.
So what approach will I take with the Transport::Session service? Not sure yet. It’ll be either the send-hash-to-constructor approach, or the setters-with-explicit-init approach. Tune in next time to hear the resolution to this dilemma…
