  • SQL command to get field of a maximum value, without making two select

    - by António Capelo
    I'm starting to learn SQL and I'm working on this exercise: I have a "books" table which holds the info on every book (including price and genre ID). I need to get the name of the genre which has the highest average price. I suppose that I first need to group the prices by genre and then retrieve the name of the highest.. I know that I can get the results GENRE VS COST with the following: select b.genre, round(avg(b.price),2) as cost from books b group by b.genre; My question is, to get the genre with the highest AVG price from that result, do I have to make: select aux.genre from ( select b.genre, round(avg(b.price),2) as cost from books b group by b.genre ) aux where aux.cost = (select max(aux.cost) from ( select b.genre, round(avg(b.price),2) as cost from books l group by b.genre ) aux); Is it bad practice or isn't there another way? I get the correct result but I'm not confortable with creating two times the same selection. I'm not using PL SQL so I can't use variables or anything like that.. Any help will be appreciated. Thanks in advance!

  • Domain Transfer Protection - need advice

    - by Jack
    Hey, I am about to purchase a domain name for a bit of money. I do not personally know the person who I am purchasing the domain name from, we have only chatted via email. The proposed process for the transfer is: The owner of the domain lowest the domain name security and emails me the domain password, I request the transfer After the request, I transfer the money via PayPal When the money has been cleared the current domain name owner confirms the transfer via the link that he receives in that email I wait for it to be transferred. The domain is currently registered with DirectNIC - http://www.directnic.com/ Is this the best practice? Seeing I am paying a bit of money for this domain name, I am worried that after the money has been cleared that I won't see the domain name or hear from the current domain name owner again. Is there a 'domain governing body' which I can report to if this is the case? Is the proposed transfer process the best solution? Any advice would be awesome. Thanks! Jack

  • vs10 not deploying all required files - then not over-writing updated files

    - by justSteve
    I'm in the habit of deploying to alternating folders (/inetpub/wwwroot/mySite & /inetpub/wwwroot/mySite2) so if something unexpected happens with the deploy i can quickly swap back to a previous version just by changing the path in IIS So i was deploying an MVC2 webapp to a empty folder figuring that VS would send up all the files it needs. Not even close. Initially, it didn't even upload a couple required nHibernate.dlls. Later, after manually copying files referenced in the thrown exceptions, i just copied all the files from the previous compile and then re-published over the top expecting VS to over-write the changed files. Failed that too. No reports of errors by VS....just failed to over-write a number of pre-existing (but changed/updated) files. Hard to believe these kinds of errors (and lack of feedback that errors were encountered) in a state of the art tool like VS. Clearly, I'm doing something wrong. I'm using VisualSVN for source control and connect to my colocated server via a VPN-based mapped network drive (so I can use FileSystem to publish). (both of which can complicate file properties) VS08 had more choices for which files it would send up - i found i needed to use the 'All files in source' on an initial deployment, the 'Replace Matching'. If I choose 'delete all existing...' I'd be back to square 1 and have to deploy with the 'All files in source project folder'. But VS10 doesn't have the 'All files in source project folder. I ended up manually copying the files - which seems not right in the extreme. Are these known issues others have to deal with? What's best practice for deploying a web-app? thx

  • archiving strategies and limitations of data in a table

    - by Samuel
    Environment: Jboss, Mysql, JPA, Hibernate Our web application will be catering to a large amount of users (~ 1,000,000) and there are a lots of child table where user specific data are stored (e.g. personal, health, forum contributions ...). What would be the best practice to archive user & user specific information. [a] Would it be wise to move the archived user & user specific information to their respective tables within the same database (e.g. user_archive, user_forum_comments_archive ...) OR [b] Would you just mark the database entries with a flag in the original table(s) and just query only non archived entries. We have a unique constraint on User.loginid, how do you handle this requirement if the users are archived via 1-[a] (i.e if a user with loginid 'samuel' gets moved into the archive table and if a new user gets added with the same name in the original table, how would you prevent this. What would be the best strategy to address the unique key constraints. We have a requirement to selectively archive records and bring it back if necessary, will you rely on database tools are would you handle this via your persistence APIs exposed by the JPA entity model.

  • How can I add a portrait layout on top of a landscape Camera SurfaceView?

    - by user319919
    I need a Camera SurfaceView for my application. The camera should be set to fixed landscape view which is done by setting android:screenOrientation="landscape" for the activity in the AndroidManifest.xml. After doing some experiments and Google researches trying to use setRotation(int) inside the camera preview implementation, I came to the conclusion, that it is obviously the common practice to get a preview with correct behaviour. Now the camera preview itself looks fine for landscape orientation. But I need to have an overlay that holds a bunch of buttons. Due to usability the user interface should be in portrait view (or even better orientation aware). There seemed no other option to me, but to fix the activity screenOrientation, so that the camera preview looks normal (in portrait mode the whole view is streched and rotated to the left) Is there a workaround to get my buttons back to portrait orientation? Or another overall approach to deal with the camera view? Parameters.setRotation(int) obvisouly didnt work. I am quite new to the Android plattform programming. Of course I dont know much about the programming tricks and workarounds yet. I did a lot of research over the last two weeks, but couldnt find the right solution so far.

  • What guidelines should be followed when using an unstable/testing/stable branching scheme?

    - by Elliot
    My team is currently using feature branches while doing development. For each user story in our sprint, we create a branch and work it in isolation. Hence, according to Martin Fowler, we practice Continuous Building, not Continuous Integration. I am interested in promoting an unstable/testing/stable scheme, similar to that of Debian, so that code is promoted from unstable = testing = stable. Our definition of done, I'd recommend, is when unit tests pass (TDD always), minimal documentation is complete, automated functional tests pass, and feature has been demo'd and accepted by PO. Once accepted by the PO, the story will be merged into the testing branch. Our test developers spend most of their time in this branch banging on the software and continuously running our automated tests. This scares me, however, because commits from another incomplete story may now make it into the testing branch. Perhaps I'm missing something because this seems like an undesired consequence. So, if moving to a code promotion strategy to solve our problems with feature branches, what strategy/guidelines do you recommend? Thanks.

  • Methods and properties in scheme - is object oriented programming possible in scheme?

    - by incrediman
    I will use a simple example to illustrate my question. In Java, C, or any other OOP language, I could create a pie class in a way similar to this: class Apple{ public String flavor; public int pieces; private int tastiness; public goodness(){ return tastiness*pieces; } } What's the best way to do that with Scheme? I suppose I could do with something like this: (define make-pie (lambda (flavor pieces tastiness) (list flavor pieces tastiness))) (define pie-goodness (lambda (pie) (* (list-ref pie 1) (list-ref pie 2)))) (pie-goodness (make-pie 'cherry 2 5)) ;output: 10 ...where cherry is the flavor, 2 is the pieces, and 5 is the tastiness. However then there's no type-safety or visibility, and everything's just shoved in an unlabeled list. How can I improve that? Sidenote: The make-pie procedure expects 3 arguments. If I want to make some of them optional (like I'd be able to in curly-brace languages like Java or C), is it good practice to just take the arguments in as a list (that is treat the arguments as a list - not require one argument which is a list) and deal with them that way?

  • Custom webserver caching

    - by Mark Kinsella
    I'm working with a custom webserver on an embedded system and having some problems correctly setting my HTTP Headers for caching. Our webserver is generating all dynamic content as XML and we're using semi-static XSL files to display it with some dynamic JSON requests thrown in for good measure along with semi-static images. I say "semi-static" because the problems occur when we need to do a firmware update which might change the XSL and image files. Here's what needs to be done: cache the XSL and image files and do not cache the XML and JSON responses. I have full control over the HTTP response and am currently: Using ETags with the XSL and image files, using the modified time and size to generate the ETag Setting Cache-Control: no-cache on the XML and JSON responses As I said, everything works dandy until a firmware update when the XSL and image files are sometimes cached. I've seen it work fine with the latest versions of Firefox and Safari but have had some problems with IE. I know one solution to this problem would be simply rename the XSL and image files after each version (eg. logo-v1.1.png, logo-v1.2.png) and set the Expires header to a date in the future but this would be difficult with the XSL files and I'd like to avoid this. Note: There is a clock on the unit but requires the user to set it and might not be 100% reliable which is what might be causing my caching issues when using ETags. What's the best practice that I should employ? I'd like to avoid as many webserver requests as possible but invalidating old XSL and image files after a software update is the #1 priority.

  • Java (or possibly other languages) learning path

    - by bgo
    I am familiar (as a self-learner) with C, python and php such that i can solve some problems involving simple steps (for example, i easily do calculations for physics lab reports with python which normally would take 4x-5x times longer with a calculator). The point here is, as doing such things, i learnt the idea / concepts of programming language and problem solving along with oop or fuctional programming etc. Recently i have started Java and, with the familiarity of other languages, i am doing well for starters but i need guidence. -I am thinking of learning syntax from sun java tutorials and then practicing with codingbat.com or similar sites. I need a reference book that i can study deeper aspects of the topics i am learning. What do you suggest about these? -The problem is (and always have been) the lack of practice. I need coding and problem-solving practices sources. I stuck at the point where i can't figure out what to do next. Can you suggest any source (possibly like codingbat)? If i could plan a learning trail, i can progress faster and efficiently. So i need ideas, comments, suggestions. Thanks in advance.

  • Should frontend and backend handled by different controllers?

    - by DR
    In my previous learning projects I always used a single controller, but know I wonder if that is good practice or even always possible. In all RESTful Rails tutorials the controllers have a show, an edit and an index view. If an authorized user is logged on, the edit view becomes available and the index view shows additional data manipulation controls, like a delete button or a link to the edit view. Now I have a Rails application which falls exactly into this pattern, but the index view is not reusable: The normal user sees a flashy index page with lots of pictures, complex layout, no Javascript requirement, ... The Admin user index has a completly different minimalistic design, jQuery table and lots of additional data, ... Now I'm not sure how to handle this case. I can think of the following: Single controller, single view: The view is split into two large blocks/partials using an if statement. Single controller, two views: index and index_admin. Two different controllers: BookController and BookAdminController None of this solutions seems perfect, but for now I'm inclined to use the 3rd option. What's the preferred way to do this?

  • Code Organization Connundrum: Web Project With Multiple Supporting DLLs?

    - by Code Sherpa
    Hi. I am trying to get a handle on the best practice for code organization within my project. I have looked around on the internet for good examples and, so far, I have seen examples of a web project with one or multiple supporting class libraries that it references or a web project with sub-folders that follow its namespace conventions. Assuming there is no right answer, this is what I currently have for code organization: MyProjectWeb This is my web site. I am referencing my class libraries here. MyProject.DLL As the base namespace, I am using this DLL for files that need to be generally consumable. For example, my class "Enums" that has all the enumerations in my project lives there. As does class MyProjectException for all exception handling. MyProject.IO.DLL This is a grouping of maybe 20 files that handle file upload and download (so far). MyProject.Utilities.DLL ALl my common classes and methods bunched up together in one generally consumable DLL. Each class follows a "XHelper" convention such as "SqlHelper, AuthHelper, SerializationHelper, and so on... MyProject.Web.DLL I am using this DLL as the main client interface. Right now, the majority of class files here are: 1) properties (such as School, Location, Account, Posts) 2) authorization stuff ( such as custom membership, custom role, & custom profile providers) My question is simply - does this seem logical? Also, how do I avoid having to cross reference DLLs from one project library to the next? For example, MyProject.Web.DLL uses code from MyProject.Utilities.DLL and MyProject.Utilities.DLL uses code from MyProject.DLL. Is this solved by clicking on properties and selecting "Dependencies"? I tried that but still don't seem to be accessing the namespaces of the assembly I have selected. Do I have to reference every assembly I need for each class library? Responses appreciated and thanks for your patience.

  • Adding a minimum display time for Silverlight splash screen.

    - by David
    When hosting a silverlight application on a webpage it is possible to use the splashscreensource parameter to specify a simple Silverlight 1.0 (xaml+javascript) control to be displayed while the real xap file is downloaded, and which can receive notification of the downloads progress through onSourceDownloadProgressChanged. If the xap file is in cache, the splash screen is not shown (and if the download only takes 1 second, the splash screen will only be shown for 1 second). I know this is not best practice in general, but I am looking for a way to specify a minimum display time for the splash screen - even if the xap cached or the download is fast, the splash screen would remain up for at least, let's say, 5 seconds (for example to show a required legal disclaimer, corporate identity mark or other bug). I do want to do it in the splash screen exclusively (rather then in the main xap) as I want it to be clean and uninterupted (for example a sound bug) and shown to the user as soon as they open the page, rather then after the download (which could take anywhere from 1 to 20+ seconds). I'd prefer not to accomplish this with preloading - replacing the splash screen with a full Silverlight xap application (with it's own loading screen), which then programmably loads and displays the full xap after a minimum wait time.

  • Python alignment of assignments (style)

    - by ikaros45
    I really like following style standards, as those specified in PEP 8. I have a linter that checks it automatically, and definitely my code is much better because of that. There is just one point in PEP 8, the E251 & E221 don't feel very good. Coming from a JavaScript background, I used to align the variable assignments as following: var var1 = 1234; var2 = 54; longer_name = 'hi'; var lol = { 'that' : 65, 'those' : 87, 'other_thing' : true }; And in my humble opinion, this improves readability dramatically. Problem is, this is dis-recommended by PEP 8. With dictionaries, is not that bad because spaces are allowed after the colon: dictionary = { 'something': 98, 'some_other_thing': False } I can "live" with variable assignments without alignment, but what I don't like at all is not to be able to pass named arguments in a function call, like this: some_func(length= 40, weight= 900, lol= 'troll', useless_var= True, intelligence=None) So, what I end up doing is using a dictionary, as following: specs = { 'length': 40, 'weight': 900, 'lol': 'troll', 'useless_var': True, 'intelligence': None } some_func(**specs) or just simply some_func(**{'length': 40, 'weight': 900, 'lol': 'troll', 'useless_var': True, 'intelligence': None}) But I have the feeling this work around is just worse than ignoring the PEP 8 E251 / E221. What is the best practice?

  • Creating a draft version of the page before publishing in Drupal 6?

    - by Marco
    I've been looking for a good way to handle revisions in Drupal, but I am yet to succeed. For some reason there is no built in way to save a draft (that I've found so far), and the modules I've tried so far do not seem to fully work. First I tried save_as_draft, which seemed to do almost what I wanted, and if I'm not mistaken, also handles CCK fields. Sadly it seems to be broken somehow, so I can't edit a page once I've saved it as a draft.. maybe I could fix it by going through the code, but that would not be my preferred solution. The other module I tried is aptly named draft, but from what I can tell, this module only handles the title and body fields, and does this in a way that appear odd to me. Is there some common practice to solve this? I couldn't imagine that nobody had to solve this before, but I haven't found any good solution to it yet. Clarification I need this functionality for already existing content, that is, I want to be able to create and edit a draft version of an already published page, while the "old" version would still be available to anonymous users.

  • Template Sort In C++

    - by wdow88
    Hey all, I'm trying to write a sort function but am having trouble figuring out how to initialize a value, and making this function work as a generic template. The sort works by: Find a pair =(ii,jj)= with a minimum value = ii+jj = such at A[ii]A[jj] If such a pair exists, then swap A[ii] and A[jj] else break; The function I have written is as follows: template <typename T> void sort(T *A, int size) { T min =453; T temp=0; bool swapper = true; while(swapper) { swapper = false; int index1 = 0, index2 = 0; for (int ii = 0; ii < size-1; ii++){ for (int jj = ii + 1; jj < size; jj++){ if((min >= (A[ii]+A[jj])) && (A[ii] > A[jj])){ min = (A[ii]+A[jj]); index1 = ii; index2 = jj; swapper = true; } } } if (!swapper) return; else { temp = A[index1]; A[index1] = A[index2]; A[index2] = temp; sort(A,size); } } } This function will successfully sort an array of integers, but not an array of chars. I do not know how to properly initialize the min value for the start of the comparison. I tried initializing the value by simply adding the first two elements of the array together (min = A[0] + A[1]), but it looks to me like for this algorithm it will fail. I know this is sort of a strange type of sort, but it is practice for a test, so thanks for any input.

  • heterogeneous comparisons in python3

    - by Matt Anderson
    I'm 99+% still using python 2.x, but I'm trying to think ahead to the day when I switch. So, I know that using comparison operators (less/greater than, or equal to) on heterogeneous types that don't have a natural ordering is no longer supported in python3.x -- instead of some consistent (but arbitrary) result we raise TypeError instead. I see the logic in that, and even mostly think its a good thing. Consistency and refusing to guess is a virtue. But what if you essentially want the python2.x behavior? What's the best way to go about getting it? For fun (more or less) I was recently implementing a Skip List, a data structure that keeps its elements sorted. I wanted to use heterogeneous types as keys in the data structure, and I've got to compare keys to one another as I walk the data structure. The python2.x way of comparing makes this really convenient -- you get an understandable ordering amongst elements that have a natural ordering, and some ordering amongst those that don't. Consistently using a sort/comparison key like (type(obj).__name__, obj) has the disadvantage of not interleaving the objects that do have a natural ordering; you get all your floats clustered together before your ints, and your str-derived class separates from your strs. I came up with the following: import operator def hetero_sort_key(obj): cls = type(obj) return (cls.__name__+'_'+cls.__module__, obj) def make_hetero_comparitor(fn): def comparator(a, b): try: return fn(a, b) except TypeError: return fn(hetero_sort_key(a), hetero_sort_key(b)) return comparator hetero_lt = make_hetero_comparitor(operator.lt) hetero_gt = make_hetero_comparitor(operator.gt) hetero_le = make_hetero_comparitor(operator.le) hetero_ge = make_hetero_comparitor(operator.gt) Is there a better way? I suspect one could construct a corner case that this would screw up -- a situation where you can compare type A to B and type A to C, but where B and C raise TypeError when compared, and you can end up with something illogical like a > b, a < c, and yet b > c (because of how their class names sorted). I don't know how likely it is that you'd run into this in practice.

  • Using "ocamlfind" to make the OCaml compiler and toplevel find (project specific) libraries

    - by CharlieP
    Hello, I'm trying to use ocamlfind with both the OCaml compiler and toplevel. From what I understood, I need to place the required libraries in the _tags file at the root of my project, so that the ocamlfind tool will take care of loading them - allowing me to open them in my modules like so : open Sdl open Sdlvideo open Str Currently, my _tags file looks like this : <*>: pkg_sdl,pkg_str I can apparently launch the ocamlfind command with the ocamlc or ocamlopt argument, provided I wan't to compile my project, but I did not see an option to launch the toplevel in the same manner. Is there any way to do this (something like "ocamlfind ocaml")? I also don't know how to place my project specific modules in the _tags file : imagine I have a module name Land. I am currently using the #use "land.ml" directive to open the file and load the module, but it has been suggested that this is not good practice. What syntax should I use in _tags to specify it should be loaded by ocamlfind (considering land.ml is not in the ocamlfind search path) ? Thank you, Charlie P. Edit : According to the first answer of this post, the _tags file is not to be used with ocamlfind. The questions above still stand, there is just a new one to the list : what is the correct way to specify the libraries to ocamlfind ?

  • User entered value validation and level of error catching

  • Core principles, rules, and habits for CS students

    - by Asad Butt
    No doubt there is a lot to read on blogs, in books, and on Stack Overflow, but can we identify some guidelines for CS students to use while studying? For me these are: Finish your course books early and read 4-5 times more material relative to your course work. Programming is the one of the fastest evolving professions. Follow the blogs on a daily basis for the latest updates, news, and technologies. Instead of relying on assignments and exams, do at least one extra, non-graded, small to medium-sized project for every programming course. Fight hard for internships or work placements even if they are unpaid, since 3 months of work 1 year at college. Practice everything, every possible and impossible way. Try doing every bit of your assignments project yourself; i.e. fight for every inch. Rely on documentation as the first source for help and samples, Google, and online forums as the last source. Participate often in online communities and forums to learn the best possible approach for every solution to your problem. (After doing your bit.) Make testing one of your habits as it is getting more important everyday in programming. Make writing one of your habits. Write something productive once or twice a week and publish it.

  • using pom for test scope dependencies

    - by IttayD
    Hi, Is it possible to create a pom file so it can be used inside another pom to add test scope dependencies? So in module E's pom.xml I have: <dependencies> <dependency> <groupId>com.example</artifactId> <artifactId>D</artifactId> <type>pom</type> <scope>test</scope> </dependency> </dependencies> So that if D's pom.xml contains dependencies on artifacts A, B, C, then these artifacts are in the compilation and execution classpath of E's tests. NOTE: the reason I want such a pom, and not rely on regular dependency resolution is that I have created a tests jar using maven-jar-plugin:test-jar and using that jar as a dependency causes maven to not use its transitive dependencies. (see http://jira.codehaus.org/browse/MNG-1378) UPDATE: this does not work for me (maybe because I'm trying to use it for the test scope): http://www.sonatype.com/books/mvnref-book/reference/pom-relationships-sect-pom-best-practice.html

  • Email function using templates. Includes via ob_start and global vars

    - by Geo
    I have a simple Email() class. It's used to send out emails from my website. <? Email::send($to, $subj, $msg, $options); ?> I also have a bunch of email templates written in plain HTML pierced with a few PHP variables. E.g. /inc/email/templates/account_created.php: <p>Dear <?=$name?>,</p> <p>Thank you for creating an account at <?=$SITE_NAME?>. To login use the link below:</p> <p><a href="https://<?=$SITE_URL?>/account" target="_blank"><?=$SITE_NAME?>/account</a></p> In order to have the PHP vars rendered I had to include the template into my function. But since include does not return the contents but rather just sends it directly to the output, I had to wrap it with the buffer functions: <? abstract class Email { public static function send($to, $subj, $msg, $options = array()) { /* ... */ ob_start(); include '/inc/email/templates/account_created.php'; $msg = ob_get_clean(); /* ... */ } } After that I realized that the PHP vars are not rendered as they are being inside of the function scope, so I had to globalize the variables inside of the template: <? global $SITE_NAME, $SITE_URL, $name; ?> <p>Dear <?=$name?>,</p> ... So the question is whether there is a more elegant solution to this? Mainly I am concerned about my workarounds using ob_start() and global. For some reason that seems to me odd. Or this is pretty much the common practice?

  • How can I get a static URL to a map image using the Google Static Maps API?

    - by Argote
    === BACKGROUND === Hello, so I've published a Web-App (still in "Beta") which uses the Flickr API to get information for the photos of a particular Flickr user and generates IPB code to post any of his/her images. While Flickr now gives you the IPB code to show the image and link back to the photo site directly on its site, my App also has the option of embeding the title, description, select EXIF data, location information, etc. into the post for the IPB forum. === PROBLEM === I've most recently added the option to integrate a Google Maps image of the photo's geolocation data into the post by using the Google Static Maps API. The problem is that the image URL I have is in the following form (including IPB [IMG] tags): [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] Which shows this example image (In practice the image size is user selectable): However, some IPB forums seem to not support dyamic image URLs which gives me a broken image, I'd like to replace the [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] with something like [IMG]http://maps.google.com/maps/api/staticmap/map0000001.png[/IMG] which should be supported by all IPB forums. Thanks in advance for your help. In case you're interested, the most recent "released" version of my Web-App can be found here: http://flickr.argote.mx/ (The changes I mention here are still on local development server).

  • How to name multiple versioned ServiceContracts in the same WCF service?

    - by Tor Hovland
    When you have to introduce a breaking change in a ServiceContract, a best practice is to keep the old one and create a new one, and use some version identifier in the namespace. If I understand this correctly, I should be able to do the following: [ServiceContract(Namespace = "http://foo.com/2010/01/14")] public interface IVersionedService { [OperationContract] string WriteGreeting(Person person); } [ServiceContract(Name = "IVersionedService", Namespace = "http://foo.com/2010/02/21")] public interface IVersionedService2 { [OperationContract(Name = "WriteGreeting")] Greeting WriteGreeting2(Person2 person); } With this I can create a service that supports both versions. This actually works, and it looks fine when testing from soapUI. However, when I create a client in Visual Studio using "Add Service Reference", VS disregards the namespaces and simply sees two interfaces with the same name. In order to differentiate them, VS adds "1" to the name of one of them. I end up with proxies called ServiceReference.VersionedServiceClient and ServiceReference.VersionedService1Client Now it's not easy for anybody to see which is the newer version. Should I give the interfaces different names? E.g IVersionedService1 IVersionedService2 or IVersionedService/2010/01/14 IVersionedService/2010/02/21 Doesn't this defeat the purpose of the namespace? Should I put them in different service classes and get a unique URL for each version?
