HexEdit Pro allows you to encrypt and decrypt all or part of a file by selecting the bytes and using the encryption or decryption command. It provides all the stream and block encryption algorithms available under the Windows "Crypto API" as well as a good internal encryption algorithm.
The Crypto API and CSPs
The Crypto API was introduced with Windows NT 4.0, mainly to address security issues to do with the growing use of the Internet. This API does not itself do anything but simply provides a standard way for Windows programs to talk with Cryptographic Service Providers (CSPs). CSPs are DLLs provided by third party software providers (although Microsoft provides the "Microsoft Base Cryptographic Provider v1.0" CSP).
Depending on the software you have installed on your computer, you will typically have a few CSPs, perhaps many, installed. Each CSP provides one or more encryption algorithms or ciphers. Different CSPs may provide different implementations of the same algorithms, but, in general, you should always decrypt using the same CSP and algorithm that you encrypted with. If you are encrypting on one machine and decrypting on another you must ensure the same CSP/algorithm is available on both machines.
If you are using Windows 95, and HexEdit Pro only shows one encryption algorithm (the HexEdit Pro internal algorithm) then the Crypto API is not available on your computer.
Algorithms
HexEdit Pro only supports use of the single-key or symmetric ciphers. (This is the traditional type of computer encryption where the same password or key is used to encrypt and decrypt.) HexEdit Pro does not support public-key ciphers, as these are only provided in the Crypto API for encryption of session keys. The Crypto API provides for two types of single-key cipher: block and stream.
Block encryption works by encrypting all the bits of a fixed size block at once. If the number of bytes to be encrypted is not a multiple of the block size then pad bytes will need to be added, hence block ciphers provided by the Crypto API increase the numbers of bytes when encrypting by up to 2 blocks. Hence, when encrypting in HexEdit Pro with a Crypto API block cipher the length of the selected bytes will increase after encryption, and decrease back to the original size after decryption. (This is not true for the HexEdit Pro internal algorithm - see below.) The Microsoft Base Cryptographic Provider v1.0 provides the RC2 block encryption algorithm.
Stream encryption, as its name suggests can take an unencrypted stream of data and produce an encrypted stream. Hence, unlike block encryption, you can encrypt any number of bytes with stream encryption. In HexEdit Pro, when you encrypt with a stream cipher, the encrypted length is the same as before encryption. The disadvantage of stream encryption is that the algorithms are typically not as secure, and implementations are slower than block encryption. The Microsoft Base Cryptographic Provider v1.0 provides the RC4 stream cipher.
The HexEdit Pro internal algorithm is a block cipher with a block size of 8 bytes (64 bits). As it does not provide padding of any incomplete last block it does not need to increase the length of the encrypted data. However, to encrypt or decrypt using this algorithm the length of the current selection must be a multiple of 8 bytes.
Passwords
The password is the "key" that is used to encrypt and decrypt. It does not matter how good your encryption algorithm is if you choose an easily guessed password. Hence a good password is at least 8 characters long, is not a common word or name in a common language, and should include some non-alphabetic characters.
HexEdit Pro has a minimum password length which defaults to 8. However, as encryption requirements vary this can be changed. For example, if you are only using HexEdit Pro for testing Crypto API functions then you might want to reduce the minimum required password length.
You can also mask your passwords using the "Mask password" check box. This is useful if anyone could possibly view your screen while you are entering the password. However, since you have no feedback about what you have typed, you have to enter a masked password twice to catch typos, otherwise you may not be able to decrypt your valuable data again.
Particular care must be taken with passwords and keystroke macros. If a password is entered while recording a macro, and the macro saved to file then the password is stored in the file for all to see. Typically, you would not enter a password while recording a macro, and to ensure that the user is prompted for a password when encrypting or decrypting you can record the "Clear Password" command in the macro; if no password has been entered since last cleared when the Encrypt or Decrypt command is invoked then HexEdit Pro will prompt for one.
Public Key Encryption
Another form of encryption that HexEdit Pro does not (yet) support is public key encryption. This has many excellent uses that I will not go into here. In this form of encryption the two keys (encryption/decryption) are not the same. One key (the public key) can be easily deduced from the other key (the private key) but it is computationally infeasible to deduce the private key from the public key. A common public key encryption algorithm is RSA.
Unfortunately, known public key algorithms are very slow compared to single-key algorithms. However, it is not necessary to encrypt all the data using public key encryption. The data itself can be encrypted using a single-key algorithm using a key that is itself encrypted using a public-key algorithm. This system of using two algorithms (a public key one and a single-key one) effectively gives the advantages of public key encryption at close to the speed of single-key encryption.
To do this the single-key encryption is performed using a randomly picked number for the encryption key. For example, to encrypt and send data, a random number is generated and encrypted using the public key encryption algorithm using the receiver's public key, and sent. Then the data itself is encrypted with the single-key algorithm using this random key. As the random value is generated and only used for only a short time, or session, it is called a session key.
The Crypto API uses public key encryption in this manner. That is public key encryption is only used to encrypt session keys for single-key encryption algorithms.

Michael Lewis has amassed quite a reputation on the back of his 2010 book The Big Short. I remember reading the book and listening to coverage on shows like This American Life's The Giant Pool of Money in 2010 to try and understand the financial crisis. This piece, however, has a lot to say about what Lewis missed in his book.
Lewis’ desire to satisfy his fan base’s craving for good guys led him to miss the most important story of our age: how a small number of operators used a nexus of astonishing leverage and camouflaged risk to bring the world financial system to its knees and miraculously walked away with their winnings.  Whether for his own profit or by accident, Lewis has denied the public the truth.
I can certainly understand the argument that Lewis was writing for a different audience (as perhaps Ezra Klein was in this piece, which was also rebuked) but I think after a cursory understanding is established, these kinds of nuanced complications are absolutely necessary for better policy building and informed decision making (including personal voting behavior) in the future.

In this article, we will explore how to make pagination links shorter and SEO friendly.
For more details about Pagination Framework, please see my other blog posts on
http://paginationspring.blogspot.com.
For SEO, we always want to make our URL search engine robot friendly. Make the following changes to our Controller:
public SeasonStatController() {
.
.
.
setRewriteUrl(true);
}
@RequestMapping(value={
URL1+"/bball-season-stat.do"
, URL2+"/bball-season-stat.do"
, URL3+"/bball-season-stat.do"
, URL4+"/bball-season-stat.do"
}, method = {RequestMethod.GET, RequestMethod.POST})
public ...
Running our example
Click "Download Zip" button on this page
https://github.com/paginationspring/pagination-example-spring4.
The content included full source code used in this example. Open command prompt and type run.bat (for window OS) or ./run.sh (for linux OS). Choose your application server and wait around 30 seconds for the server to startup.
After you start the server, go to http://localhost:8080/pagination-example-spring4
You can try navigating through page 1, 2… etc or sort a column. As you can see, the url is now shorter and friendlier.

As Madison Craft Beer Week marches on towards its close this weekend, the amount and variety of beer I've had has grown to an incredible level. This is one of the many times I wish I had an easy way to keep track of what I've drank (a la Trinker or Untappd), but I feel a little more legit that I don't. I also wish I had some way to easily keep track of plans/ideas I want to do in the near future (e.g. "Get growlers from Hydro Street"), but *coughcough*moreonthattocomesoon*cough*.
Anywho, in my own little celebration, I've been saving some high-quality beers to make pancakes out of this week, and I've been doing more than the usual one-post-per-week. Today's entry is a very special specialty brew out of Tyranena Brewing Company. Tyranena has their "Brewers Gone Wild" series, which are one-off experimental brews from their creative and talented brewers. I was at a beer tasting a few months ago and they were sampling the current batch, which was Benji's Imperial Smoked Porter with Chipotle.
|
|
|
Oh baby. Get excited.
|
These come in 4-packs, so you have to use them wisely. I had them for a few months before I cracked any open. The first one I had I don't recall the occasion, but the beer was much less enjoyable/flavorful than I remembered it from the tasting. I think it was too cold. The 2nd I took to Rochester to give to my beer buddy, Greg. This is the 3rd out of the pack, and I'm happy to report it was much more enjoyable this time around. A nice, rich, full-bodied Imperial Porter with just the lightest tinge of pepper spice on the finish. I learned taking larger mouthfuls gives you more of the pepper taste.
But enough about the beer, on to the pancakes!
Prep/Cooking:
|
|
|
Aww yeah WI Beer Expo glass. So sad that died :(
|
Benji's porter, in batter form, was nothing impressive. It kept a lot of the big-bodied flavor that were characteristic of the beer, but it lost some of the subtler tones, and the chipotle pepper all but disappeared. I didn't quite test out the "more of a mouthful" hypothesis about the flavor, though, as that would probably be a bit overwhelming. The pancakes came out pretty average - not too fluffy, not too flat, nothing really weird about them. They had a nice brown color to them thanks to the imperial porter.
Results:
|
|
|
Notice the amount of beer left in the glass goes down over time...
|
I wasn't sure what to expect with this beer. I've done a few other smoked pancakes in the past with mixed results - sometimes they come out burnt-y, sometimes they're delicious. Add the chipotle in here and I was a little apprehensive before digging into them. But, I forged on. For Science!
My apprehension was completely misplaced with this one, though. The malty deliciousness of the porter came through magnificently in these pancakes, giving them a rich, wholesome flavor. I'm not sure if it's a mixture of the smoke, the chipotle, or the malts, but they were almost savory. None of the three flavor tones really overpowered the other, but somehow a little batter, oil, and heat brought out that combination moreso than in liquid form.
The Ternary Scale:
|
|
|
Still disappointed by the waste of good pancake with the syrup
|
Pancakes: 2 - It's kind of hard for me to say "Go out and get these and make pancakes" given it's a once-in-a-lifetime sort of release (unless it's wildly popular, then maybe they'll make it again), but if you can get your hands on some, do it up. I know the Mason Lounge in Madison still has bottles...
Syrup: 0 - No way. The syrup actually made these worse. The savoriness of the smoke, chipotle, and malt was washed out by the sweet syrupy goodness (or, in this case, badness). What a waste.

Hey! Socket programming got you down? Is this stuff just a little too difficult to figure out from the man pages? You want to do cool Internet programming, but you don't have time to wade through a gob of structs trying to figure out if you have to call bind() before you connect(), etc., etc.
Well, guess what! I've already done this nasty business, and I'm dying to share the information with everyone! You've come to the right place. This document should give the average competent C programmer the edge s/he needs to get a grip on this networking noise.
This document has been written as a tutorial, not a reference. It is probably at its best when read by individuals who are just starting out with socket programming and are looking for a foothold. It is certainly not the complete guide to sockets programming, by any means.
Hopefully, though, it'll be just enough for those man pages to start making sense... :-)
The code contained within this document was compiled on a Linux PC using Gnu's gcc compiler. It should, however, build on just about any platform that uses gcc. Naturally, this doesn't apply if you're programming for Windows--see the section on Windows programming, below.
This official location of this document is at California State University, Chico, at http://www.ecst.csuchico.edu/~beej/guide/net/.
When compiling for Solaris or SunOS, you need to specify some extra command-line switches for linking in the proper libraries. In order to do this, simply add "-lnsl -lsocket -lresolv" to the end of the compile command, like so:
$ cc -o server server.c -lnsl -lsocket -lresolv |
If you still get errors, you could try further adding a "-lxnet" to the end of that command line. I don't know what that does, exactly, but some people seem to need it.
Another place that you might find problems is in the call to setsockopt(). The prototype differs from that on my Linux box, so instead of:
int yes=1; |
enter this:
char yes='1'; |
As I don't have a Sun box, I haven't tested any of the above information--it's just what people have told me through email.
I have a particular dislike for Windows, and encourage you to try Linux, BSD, or Unix instead. That being said, you can still use this stuff under Windows.
First, ignore pretty much all of the system header files I mention in here. All you need to include is:
#include <winsock.h> |
Wait! You also have to make a call to WSAStartup() before doing anything else with the sockets library. The code to do that looks something like this:
#include <winsock.h> { WSADATA wsaData; // if this doesn't work //WSAData wsaData; // then try this instead if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0) { fprintf(stderr, "WSAStartup failed.\n"); exit(1); } |
You also have to tell your compiler to link in the Winsock library, usually called wsock32.lib or winsock32.lib or somesuch. Under VC++, this can be done through the Project menu, under Settings.... Click the Link tab, and look for the box titled "Object/library modules". Add "wsock32.lib" to that list.
Or so I hear.
Finally, you need to call WSACleanup() when you're all through with the sockets library. See your online help for details.
Once you do that, the rest of the examples in this tutorial should generally apply, with a few exceptions. For one thing, you can't use close() to close a socket--you need to use closesocket(), instead. Also, select() only works with socket descriptors, not file descriptors (like 0 for stdin).
To get more information about Winsock, read the Winsock FAQ and go from there.
Finally, I hear that Windows has no fork() system call which is, unfortunately, used in some of my examples. Maybe you have to link in a POSIX library or something to get it to work, or you can use CreateProcess() instead. fork() takes no arguments, and CreateProcess() takes about 48 billion arguments. Welcome to the wonderful world of Win32 programming.
I'm generally available to help out with email questions so feel free to write in, but I can't guarantee a response. I lead a pretty busy life and there are times when I just can't answer a question you have. When that's the case, I usually just delete the message.
As a rule, the more complex the question, the less likely I am to respond. If you can narrow down your question before mailing it and be sure to include any pertinent information (like platform, compiler, error messages you're getting, and anything else you think might help me troubleshoot), you're much more likely to get a response.
If not, hack on it some more, try to find the answer, and if it's still elusive, then write me again with the information you've found and hopefully it will be enough for me to help out.
Now that I've badgered you about how to write and not write me, I'd just like to let you know that I fully appreciate all the praise the guide has received over the years. It's a real morale boost, and it gladdens me to hear that it is being used for good! :) Thank you!

When Have You Tested Enough?
@cwgem recently asked: ‘Curiously throwing this out there. For test driven development, what do you consider to be “enough testing”?’
To which I respond:
Yesterday I tweeted, “I only test the code I want to work. I trust my code the least, then my team’s, then libraries.”
Not sure I really answered your original question tho. In TDD the idea of ‘enough’ tests may be missing the point. I don’t claim to TDD all the time, or to do it perfectly when I do, but one of the things that has been an apparent focus of TDD to me is the focus on tests driving design.
More to the point, the purpose of TDD as I understand it is to express expectations as test code, which unlike documentation needs to stay in sync with the changing codebase. By driving out our object from tests we create simpler and more focused methods.
In example, last year I was working on calculator code for a client which had some wonky business logic. I drove out the code using tests, and came up with what I thought was an elegant design (a bunch of single-line methods) in a pretty quick cycle. However, I had misunderstood the requirements when I wrote the tests, and the client wasn’t happy.
I quickly found out how the requirements I had written down in tests differed from reality, changed the tests, then made each failing example go green. If I had designed this without tests behind it, I would have likely written some dense conditional logic, and when it failed to meet expectations it would have been faster to throw it away and try again than to refactor it. The design that tests encourage was better for dealing with change.
I have when writing tests for unfamiliar languages written tests for things like setting variables. It was the simplest thing that I could think to test and writing that test gave me the confidence and familiarity to be able to soldier bravely onward. However, I wouldn’t keep a test of that sort in the codebase. There is nothing too small to write a test for at least once, so that you can prove to yourself that your expectations match the reality of the execution of code.  The tests that I want in my test suite are ones which prove that the business logic of my application works, not that the language or libraries work.
Or more to the point, I only test the code I want to work. I want code which I trust the least to work the most, and I trust new code less than old code, changed code less than old code, my code less than my team’s code, and my team’s code less than library or framework code.

In order for this to work, you also need to modify your main.m to tell UIApplicationMain to use your delegate class (in this example, AppDelegate) as the principal class:
int retVal = UIApplicationMain(argc, argv, @"AppDelegate", @"AppDelegate");


With fetch
method it’s fairly easy to upload a file.
How to resume the upload after lost connection? There’s no built-in option for that, but we have the pieces to implement it.
Resumable uploads should come with upload progress indication, as we expect big files (if we may need to resume). So, as fetch
doesn’t allow to track upload progress, we’ll use XMLHttpRequest.
To resume upload, we need to know how much was uploaded till the connection was lost.
There’s xhr.upload.onprogress
to track upload progress.
Unfortunately, it won’t help us to resume the upload here, as it triggers when the data is sent, but was it received by the server? The browser doesn’t know.
Maybe it was buffered by a local network proxy, or maybe the remote server process just died and couldn’t process them, or it was just lost in the middle and didn’t reach the receiver.
That’s why this event is only useful to show a nice progress bar.
To resume upload, we need to know exactly the number of bytes received by the server. And only the server can tell that, so we’ll make an additional request.
First, create a file id, to uniquely identify the file we’re going to upload:
That’s needed for resume upload, to tell the server what we’re resuming.
If the name or the size or the last modification date changes, then there’ll be another fileId
.
Send a request to the server, asking how many bytes it already has, like this:
let response = await fetch("status", {
headers: {
"X-File-Id": fileId,
},
});
// The server has that many bytes
let startByte = +(await response.text());
This assumes that the server tracks file uploads by X-File-Id
header. Should be implemented at server-side.
If the file doesn’t yet exist at the server, then the server response should be 0
Then, we can use Blob
method slice
to send the file from startByte
:
xhr.open("POST", "upload", true);
// File id, so that the server knows which file we upload
xhr.setRequestHeader("X-File-Id", fileId);
// The byte we're resuming from, so the server knows we're resuming
xhr.setRequestHeader("X-Start-Byte", startByte);
xhr.upload.onprogress = (e) => {
console.log(`Uploaded ${startByte + e.loaded} of ${startByte + e.total}`);
};
// file can be from input.files[0] or another source
xhr.send(file.slice(startByte));
Here we send the server both file id as X-File-Id
, so it knows which file we’re uploading, and the starting byte as X-Start-Byte
, so it knows we’re not uploading it initially, but resuming.
The server should check its records, and if there was an upload of that file, and the current uploaded size is exactly X-Start-Byte
, then append the data to it.
Here’s the demo with both client and server code, written on Node.js.
It works only partially on this site, as Node.js is behind another server named Nginx, that buffers uploads, passing them to Node.js when fully complete.
But you can download it and run locally for the full demonstration:
[codetabs src=“upload-resume” height=200]
As we can see, modern networking methods are close to file managers in their capabilities – control over headers, progress indicator, sending file parts, etc.
We can implement resumable upload and much more.

| OptimisticLockingFailureException | Exception thrown on an optimistic locking violation. |
| PermissionDeniedDataAccessException | Exception thrown when the underlying resource denied a permission to access a specific element, such as a specific database table. |
| PessimisticLockingFailureException | Exception thrown on a pessimistic locking violation. |
| RecoverableDataAccessException | Data access exception thrown when a previously failed operation might be able to succeed if the application performs some recovery steps and retries the entire transaction or in the case of a distributed transaction, the transaction branch. |
| TransientDataAccessException | Root of the hierarchy of data access exceptions that are considered transient - where a previously failed operation might be able to succeed when the operation is retried without any intervention by application-level functionality. |
| TransientDataAccessResourceException | Data access exception thrown when a resource fails temporarily and the operation can be retried. |
| TypeMismatchDataAccessException | Exception thrown on mismatch between Java type and database type: for example on an attempt to set an object of the wrong type in an RDBMS column. |
| UncategorizedDataAccessException | Normal superclass when we can't distinguish anything more specific than "something went wrong with the underlying resource": for example, a SQLException from JDBC we can't pinpoint more precisely. |
Exception hierarchy enabling sophisticated error handling independent of the data access approach in use. For example, when DAOs and data access frameworks use the exceptions in this package (and custom subclasses), calling code can detect and handle common problems such as deadlocks without being tied to a particular data access strategy, such as JDBC.
All these exceptions are unchecked, meaning that calling code can leave them uncaught and treat all data access exceptions as fatal.
The classes in this package are discussed in Chapter 9 of Expert One-On-One J2EE Design and Development by Rod Johnson (Wrox, 2002).

Protocols
The following protocols are available globally.
-
A
TypeSafeCredentials
plugin for HTTP basic authentication. This protocol will be implemented by a Swift object defined by the user. The plugin must implement averifyPassword
function which takes a username and password as input and returns an instance ofSelf
on success ornil
on failure. This instance must contain the authenticationprovider
(defaults to “HTTPBasic”) and anid
, uniquely identifying the user. The users object can then be used in TypeSafeMiddlware routes to authenticate with HTTP basic.Usage Example:
See morepublic struct MyHTTPBasic: TypeSafeHTTPBasic { public var id: String static let users = ["John" : "12345", "Mary" : "qwerasdf"] public static let realm = "Login message" public static func verifyPassword(username: String, password: String, callback: @escaping (MyHTTPBasic?) -> Void) { if let storedPassword = users[username], storedPassword == password { callback(MyHTTPBasic(id: username)) } else { callback(nil) } } } struct User: Codable { let name: String } router.get("/protected") { (authedUser: MyHTTPBasic, respondWith: (User?, RequestError?) -> Void) in let user = User(name: authedUser.id) respondWith(user, nil) }
Declaration
Swift
public protocol TypeSafeHTTPBasic : TypeSafeCredentials

Oli Clive-Griffin
A lot of the time it's easy to get into an intellectual rut while programming and get lost in your own head. Self-awareness allows you to mediate your attention and approach a problem in an effective and efficient way.
Empathy allows us to connect with our fellow developers and work together productively. The productivity of two people working together is often greater than the sum of its parts.
Honestly, I thought it would be mostly useless and a waste of time. Although I still haven't loved it, there were some moments where I could see the value in what I was doing. For example, the values and identity activity caused a surprising amount of introspection.
A problem that was too common for me as I was doing the kata was simple syntax errors. These were errors that should have been able to be fixed with a simple look at the documentation but instead, took ages to find.
I often used console logging to isolate the problem, for example, by logging the results of functions to see if they had worked as expected. However, once I had the problem isolated, which was fairly quick, I spent too long just blindly trying solutions without checking to see whether the most basic aspect of the code - the syntax - was correct. Had I checked the documentation immediately after isolating the dysfunctional code, I might have saved an hour or so of blind and incredibly frustrating experimentation.
I will remember to make absolutely sure that my syntax is correct before trying other, more complex types of problem solving, because syntax errors are - at least for me - the most common, and most easily fixed problems i encounter while coding.
When solving the ‘where are you’ kata, I decided to use the array.find method. I wasn’t super familiar with the method syntax so after having a look at some examples in the documentation (I love examples) I copied and pasted an example into my code, replacing their variables with mine and paying attention to how this translated between the two contexts.
This was a very fast and satisfying way of gaining a just-in-time understanding of the syntax. I think it’s important to realise that for most programming problems, especially the most fundamental ones like the basic syntax of a method, there’s almost always information readily available through google. Instead of trying to know everything, we should accept that we are practically cyborgs, with a large part of our “knowledge” stored online and ready at hand at a moment’s notice.
I will continue to shamelessly consult google with my programming problems, embracing the concept of just-in-time learning.
Our core beliefs subtly, but very strongly influence everything we do, so when we know we can grow and improve, this is almost permission for our brains to do so. Understanding neuroplasticity is the key to a growth mindset which, in turn, is the key to improvement of any kind. We can also essentially hack the body into a state of neuroplasticity
raising the stakes helps to increase motivation, which in turn increases neuroplasticity
“neurons that fire together, wire together” repetitive practice takes advantage of neuroplasticity. This goes without saying, I will be practicing all the time
A website’s main purpose is to display information. But if the information isn’t displayed in a nice way, no-one is ever going to pay attention. Websites ideally are full of useful information, displayed in an aesthetically pleasing way that is intuitive, easy to read, and easy to navigate around.
Emotional intelligence is the ability to recognise, understand and channel your emotions and those of the people around you. It is the way we navigate through our human world, interacting with others, and understanding ourselves.
one of the most important uses of CSS is to position html elemtents on the page. we will be covering 4 of the most common types of css positioning
I want to start a tech startup(s).
Explain a situation where you have had an ethical decision to make. Discuss how you weighed up the values involved in that decision, the decision you made and the consequences of the action you took.
I honestly can't think of a serious ethical decision I've had to make recently. But rather a set of small ones. I've been working in my parents restaurant/cinema over the winter and the busiest days it gets really, really busy. Sometimes when I'd dropped the ball in some way or another - forgetting to put a customer's order through, forgetting to clean a cinema - I'd instinctively tell white lies to cover up for myself. After doing this a few times, I noticed what I was doing and was quite disappointed with myself. I'd always thought I was a radically honest person. but under stress, and when being held accountable by my workmates, I had allowed my standards to slip. since that, and especially since dwelling on this idea while doing this exercise, I've committed to being that same radically honest person I have been in the past


I have been studying Hacettepe University for 5 years as computer science student.
I live in Ankara
I am at this major since i am interested in programming.
Also i'm interested in artificial intelligence,computer
vision.This major can be enabled to learn them.
I love going to cinema and i love Marvel films.
My favourite marvel character is Iron Man and
i am fan of Robert Downey jr.

Planners¶
Python module for path planning algorithms on a 2D grid world.
-
algorithms.
planner_optimal
(world_state, robot_pose, goal_pose)¶ Optimal A* path planner with manhattan distance heuristic. Assumes admissible heuristic.
Parameters: - world_state – 2D matrix representing the world
- robot_pose – Tuple of robot pose
- goal_pose – Tuple of goal pose
Returns: Returns path, a list of tuples of (x, y) coordinates - Returns None if there is an error
-
algorithms.
planner_random
(world_state, robot_pose, goal_pose, max_step_number=10000)¶ Random walk path planner
Parameters: - world_state – 2D matrix representing the world
- robot_pose – Tuple of robot pose
- goal_pose – Tuple of goal pose
- max_step_number – Max number of iterations before terminating
Returns: Returns path, a list of tuples of (x, y) coordinates - Returns None if there is an error
Planners in this module compute a path from start_pose to goal_pose given a world represented by a 2D list, with 1’s denoting obstacles and 0’s denoting free space.
The random planner is implemented as a simple algorithm where random steps are taken from the start_pose until goal_pose is reached within max_step_number
steps. The last sqrt(max_step_number)
steps are stored in the list visited
, and if possible, the random walk refrains from visiting cells in this list. The planner returns a path, a list of coordinates to reach the goal_pose
from the start_pose
, if successful. If a feasible path is not calculated in max_step_number
steps, or the start or goal states are occupied, the planner will return None
.
The optimal planner is implemented as a A* Search algorithm. The planner returns a path if successful, and returns None
if it fails. The heuristic is selected as the manhattan distance, which is proven to be admissible in orthogonally connected grid worlds.
Simple Example¶
# Simple example for planner usage
# User can adjust parameters world, start_pose, and goal_pose to get results on planners
world = [[1, 1, 1, 0, 0, 0, 0],
[1, 1, 1, 0, 0, 1, 0],
[1, 0, 0, 0, 0, 1, 1],
[1, 0, 0, 1, 0, 0, 0],
[1, 1, 1, 0, 0, 0, 0],
[1, 0, 1, 1, 1, 1, 0],
[1, 0, 1, 0, 0, 1, 0],
[1, 0, 0, 1, 0, 0, 0],
[1, 0, 0, 0, 0, 0, 0],
[1, 1, 1, 1, 0, 0, 0]]
start_pose = (3, 1)
end_pose = (5, 1)
t = time.time()
optimal_path = planner_optimal(world, start_pose, end_pose)
print "Time elapsed: ", tools.sec_to_ms(time.time() - t), "ms"
print "Optimal path: ", optimal_path
print "Length: ", tools.path_length(optimal_path)
t = time.time()
random_path = planner_random(world, start_pose, end_pose)
print "Time elapsed: ", tools.sec_to_ms(time.time() - t), "ms"
print "Random path: ", random_path
print "Length: ", tools.path_length(random_path)
The above code will print:
Time elapsed: 0.618934631348 ms

- tiny.map.scen 21x30 map with relatively few open spaces. Similar to a generic indoor environment.
- dragonage.map.scen 49x49 map ripped from the video game Dragon Age: Origins. Similar to a generic outdoor environment.
- maze.map.scen 512x512 map with very complex corridors of width 1. Artificial environment for testing.
Each problem set contains hundreds of problems with valid start and goal positions, and a world map. The world map representation is slightly different, with .
denoting empty states. The world maps are converted to 1 and 0 representation with the tools.read_world_file()
function.
100 problems are picked randomly from each problem set, and path lengths and computation times are calculated. Means and standard deviations are reported for each problem set.
The A* algorithm can find the optimal path reasonably fast in all three problems. Even the complicated maze problem can be solved in about a second on average.
The random planner is only viable in tiny maps with narrow corridors. Compared to the A* algorithm, the random planner performed an order of magnitude worse. Even in the smallest map in the problem set, the mean path length is 357.88 compared to A*’s 14.92, and the computation speed is 7 times slower. The difference is even larger with the intermediate sized map, and the random planner completely fails to find a path in 100000 steps, thus, no results are provided on the random planner with the maze map.
Code Correctness¶
Optimality of the A* Algorithm has been verified by selecting many problems from the problem sets and comparing the path lengths computed with the planner with the values reported in the sets. All tests were passed. Since the problem sets are originally 8-connected, octile neighborhoods were allowed when testing this way.
Remarks on Complexity¶
The A* algorithm has a time and space complexity of O(b^d), where b is the branching factor, and d is the depth of the optimal path. The branching factor is 4 when the grid world is orthogonally connected. For configuration spaces with relatively few number of nodes, and static obstacles, A* is one of the most reliable algorithms when an admissible heuristic is used.
The random walk algorithm is stochastic by its nature. There is no guarantee that the goal will be found in a certain number of steps. However, the algorithm is probabilistically complete. As the number of steps taken approaches infinity, the probability of finding a solution approaches 1. The worst case scenario of this algorithm is unbounded, however an expected time for covering all nodes in the graph can be stated.
Let n be the number of nodes in the graph, and m be the number of connections. In an undirected graph, we would have a maximum of n(n-1) connections. In order to have an expected value of covering all the connections, we would have to visit each node n-1 times. Thus, the expected cover time would be n(n-1)(n-1), which can be stated as O(n^3). However, in an orthogonally connected grid world, the number of connections would be 4n, and the complexity can be stated as O(n^2).

Darrell Clarke's challenge to Walsall strikers
Walsall boss Darrell Clarke has challenged his strikers to improve their play with their backs to goal after his side’s 1-0 win away at Port Vale.
by Liam KeenForward Elijah Adebayo got the only goal of the game in the first minute of the second half.
A superb defensive display secured the three points but Clarke was unhappy with his team’s possession of the ball.
“We have to be better with our back to play, strikers look after the ball,” he said. “I can’t remember how many times we’ve given the ball away with our back to play.
“Just keep the ball, find the pass, make another movement. The basics of possession football.
“It’s something we have to look at and obviously improve on.
“Against Chelsea I thought for 70 minutes we were outstanding with the ball, moving it on the front foot.
“But it’s three points away from home which in this league is very hard to come by.
“We’ll take the positives, I know I’m just a miserable git but it’s just the way I am.”
Midfielder Stuart Sinclair returned to the side after missing eight games through an unspecified injury.
The experienced battler lasted the full 90 minutes at Vale Park and Clarke was pleased to have him back.
“It’s nice to have the beard running around isn’t it,” he added. “His heart and desire. It’s testament to the way he looks after himself to get 90 minutes.”
