  • smallest filesize for transparent single pixel image

    - by zaf
    I'm looking for the smallest (in terms of filesize) transparent 1 pixel image. Currently I have a gif of 49 bytes which seems to be the most popular. But I remember many years ago having one which was less than 40 bytes. Could have been 32 bytes. Can anyone do better? Graphics format is no concern as long as modern web browsers can display it and respect the transparency.

  • hibernate3-maven-plugin: entiries in different maven projects, hbm2ddl fails

    - by Mike
    I'm trying to put an entity in a different maven project. In the current project I have: @Entity public class User { ... private FacebookUser facebookUser; ... public FacebookUser getFacebookUser() { return facebookUser; } ... public void setFacebookUser(FacebookUser facebookUser) { this.facebookUser = facebookUser; } Then FacebookUser (in a different maven project, that's a dependency of a current project) is defined as: @Entity public class FacebookUser { ... @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } Here is my maven hibernate3-maven-plugin configuration: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>2.2</version> <executions> <execution> <phase>process-classes</phase> <goals> <goal>hbm2ddl</goal> </goals> </execution> </executions> <configuration> <components> <component> <name>hbm2ddl</name> <implementation>jpaconfiguration</implementation> </component> </components> <componentProperties> <ejb3>false</ejb3> <persistenceunit>Default</persistenceunit> <outputfilename>schema.ddl</outputfilename> <drop>false</drop> <create>true</create> <export>false</export> <format>true</format> </componentProperties> </configuration> </plugin> Here is the error I'm getting: org.hibernate.MappingException: Could not determine type for: com.xxx.facebook.model.FacebookUser, at table: user, for columns: [org.hibernate.mapping.Column(facebook_user)] I know that FacebookUser is on the classpath because if I make facebook user transient, project compiles fine: @Transient public FacebookUser getFacebookUser() { return facebookUser; }

  • awk or perl file editing & manipulation

    - by paul44
    I have a standard passwd file & a usermap file - which maps unix name (eg jbloggs) with AD account name (eg bloggsjoe) in the format: jbloggs bloggsjoe jsmith smithjohn ... etc. How can I edit the passwd file to swap the original unix name with the AD account name so each line of the passwd file has the AD account name instead. Appreciate any help for a perl learner.

  • Java: Implement own message queue (threadsafe)

    - by derMax
    The task is to implement my own messagequeue that is thread safe. My approach: public class MessageQueue { /** * Number of strings (messages) that can be stored in the queue. */ private int capacity; /** * The queue itself, all incoming messages are stored in here. */ private Vector<String> queue = new Vector<String>(capacity); /** * Constructor, initializes the queue. * * @param capacity The number of messages allowed in the queue. */ public MessageQueue(int capacity) { this.capacity = capacity; } /** * Adds a new message to the queue. If the queue is full, it waits until a message is released. * * @param message */ public synchronized void send(String message) { //TODO check } /** * Receives a new message and removes it from the queue. * * @return */ public synchronized String receive() { //TODO check return "0"; } } If the queue is empty and I call remove(), I want to call wait() so that another thread can use the send() method. Respectively, I have to call notifyAll() after every iteration. Question: Is that possible? I mean does it work that when I say wait() in one method of an object, that I can then execute another method of the same object? And another question: Does that seem to be clever?

  • Codeigniter Pagination: Run the Query Twice?

    - by Frank
    I'm using codeigniter and the pagination class. This is such a basic question, but I need to make sure I'm not missing something. In order to get the config items necessary to paginate results getting them from a MySQL database it's basically necessary to run the query twice is that right? In other words, you have to run the query to determine the total number of records before you can paginate. So I'm doing it like: Do this query to get number of results $this->db->where('something', $something); $query = $this->db->get('the_table_name'); $num_rows = $query->num_rows(); Then I'll have to do it again to get the results with the limit and offset. Something like: $this->db->where('something', $something); $this->db->limit($limit, $offset); $query = $this->db->get('the_table_name'); if($query->num_rows()){ foreach($query->result_array() as $row){ ## get the results here } } I just wonder if I'm actually doing this right in that the query always needs to be run twice? The queries I'm using are much more complex than what is shown above.

  • How to read date from the form and calculate a timestamp

    - by Vafello
    I would like to calculate a timestamp based on the input date. I would like to calculate it from the user input (something like 12/12/2011) I guess I need a function that changes the format to something readable for php and then calculate timestamp for this date. Maybe I should use strtotime() function? Any ideas will be appreciated. $date = $_POST['date']; <input type="text" name="date" value="">

  • Web based printing from a Django application?

    - by lud0h
    Is there any recent developments in web based printing? I know using @media print in CSS, PDF based solution or iTextSharp but they are not really easy (except @media print) but alignment is little tricky if receipt contains barcodes or if I have to format for A5 etc., Is there anything new in HTML5 which will support this? I would like to print receipts from a Django based webapplication. Any tips? Thanks.

  • Extract Rules from InfoPath Form

    - by marr75
    Is there a way to automatically grab the rules, in their original, human readable format from an InfoPath 2007 form (probably the manifest.xsf file, they're not human readable here)? A commercial tool would be fine, even. We're looking to build a summary of the rules as they appear in the design form for easy browsing by a maintenance team.

  • DataGrid: dynamic DataTemplate for dynamic DataGridTemplateColumn

    - by Lukas Cenovsky
    I want to show data in a datagrid where the data is a collection of public class Thing { public string Foo { get; set; } public string Bar { get; set; } public List<Candidate> Candidates { get; set; } } public class Candidate { public string FirstName { get; set; } public string LastName { get; set; } ... } where the number of candidates in Candidates list varies at runtime. Desired grid layout looks like this Foo | Bar | Candidate 1 | Candidate 2 | ... | Candidate N I'd like to have a DataTemplate for each Candidate as I plan changing it during runtime - user can choose what info about candidate is displayed in different columns (candidate is just an example, I have different object). That means I also want to change the column templates in runtime although this can be achieved by one big template and collapsing its parts. I know about two ways how to achieve my goals (both quite similar): Use AutoGeneratingColumn event and create Candidates columns Add Columns manually In both cases I need to load the DataTemplate from string with XamlReader. Before that I have to edit the string to change the binding to wanted Candidate. Is there a better way how to create a DataGrid with unknown number of DataGridTemplateColumn? Note: This question is based on dynamic datatemplate with valueconverter

  • Java: Infinite loop using Scanner in.hasNextInt()

    - by Tomek
    Hi everyone, I am using the following code: while (invalidInput) { // ask the user to specify a number to update the times by System.out.print("Specify an integer between 0 and 5: "); if (in.hasNextInt()) { // get the update value updateValue = in.nextInt(); // check to see if it was within range if (updateValue >= 0 && updateValue <= 5) { invalidInput = false; } else { System.out.println("You have not entered a number between 0 and 5. Try again."); } } else { System.out.println("You have entered an invalid input. Try again."); } } However, if I enter a 'w' it will tell me "You have entered invalid input. Try Again." and then it will go into an infinite loop showing the text "Specify an integer between 0 and 5: You have entered an invalid input. Try again." Why is this happening? Isn't the program supposed to wait for the user to input and press enter each time it reaches the statement: if (in.hasNextInt()) Thanks in advance, Tomek

  • bind event handler on keydown listen function JavaScript jQuery

    - by user1644123
    I am trying to bind a handler to an event. The event is a keydown function. The handler will listen for hit variables to produce one of two conditions. The 1st condition (odd number of hits) will perform 1 function, the 2nd (even number of hits) will perform another function. To elaborate, the 1st function will scroll to one element, the 2nd will scroll to another element. My syntax may be the wrong approach, but it works for the 1st condition, but not the 2nd. I think I have the conditional statement in the wrong place. How can I rewrite this to work as intended? Thank you kindly, in advance! $(document).keydown(function(e) { switch (e.which) { case 37: break; case 38: break; case 39: break; case 40: //bottom arrow key var hits = 0; if (hits % 2 !== 0) { $('#wrap').animate({ scrollTop: $("#scrollToHere").offset().top }, 2800); } else { $('#wrap').animate({ scrollTop: $("#scroll2ToHere").offset().top }, 2800); } hits++; return false; break; } })? *I moved "var hits = 0;" to the top, but it only works! But is there a way I can reset the whole thing after every two hits? I want to reset because when there is a bug and if I press a 3rd time it scrolls to the very top of the page, where there is no element to make it scroll to the top. Why would it scroll to the top of the page if I never scripted it to do so?? *

  • HATEOAS - Discovery and URI Templating

    - by Paul Kirby
    I'm designing a HATEOAS API for internal data at my company, but have been having troubles with the discovery of links. Consider the following set of steps for someone to retrieve information about a specific employee in this system: User sends GET to http://coredata/ to get all available resources, returns a number of links including one tagged as rel = "http://coredata/rels/employees" User follows HREF on the rel from the first request, performing a GET at (for example) http://coredata/employees The data returned from this last call is my conundrum and a situation where I've heard mixed suggestions. Here are some of them: That GET will return all employees (with perhaps truncated data), and the client would be responsible for picking the one it wants from that list. That GET would return a number of URI templated links describing how to query / get one employee / get all employees. Something like: "_links": { "http://coredata/rels/employees#RetrieveOne": { "href": "http://coredata/employees/{id}" }, "http://coredata/rels/employees#Query": { "href": "http://coredata/employees{?login,firstName,lastName}" }, "http://coredata/rels/employees#All": { "href": "http://coredata/employees/all" } } I'm a little stuck here with what remains closest to HATEOAS. For option 1, I really do not want to make my clients retrieve all employees every time for the sake of navigation, but I can see how using URI templating in example two introduces some out-of-band knowledge. My other thought was to use the RetrieveOne, Query, and All operations as my cool URLs, but that seems to violate the concept that you should be able to navigate to the resources you want from one base URI. Has anyone else managed to come up with a good way to handle this? Navigation is dead simple once you've retrieved one resource or a set of resources, but it seems very difficult to use for discovery.

  • a question about rails general practice with REST, json, and ajax

    - by Nik
    Hi all, I have this question concerning REST I think: I have read a few rest tutorials and the feeling I get from them is that each action in a restful controller tends to be lean and almost single purpose: "Index gives off a collection of a model show gives off one model edit/new a prep place for changing/create a model update/create changes and makes new model deletes removes one model" After reading all these tutorials, rest seems to be to be a means to create an interface for a model, much like active resource type of thing. the mantra seems to be "controller provides data and data only and is also pretty convention over configuration, so expect projects_path to return a bunch of projects" I can understand that, and I like the cleanliness. But here's when I run into some trouble in reality in applying these guidelines: say three models, Project with attrib title, User with attrib name, and Location with attrib address. Say in views/users/index.html.erb, I want to use Ajax to fetch and display a project in a div#project_display when the user clicks on a project element, I know that I can use views/projects/show.js.rjs like this: page.replace_html 'project_display' "#{@project.name}" where in the projects_controller.rb def show @project = Project.find(params[:id]) repsond_to do |format| format.js and other formats... end end I have no problem in doing that for a couple of years now. BUT doesn't that mean that my JS response for the project#show action is LOCkED to present data to div#project_display element and show only whatever I that rjs template says it should show? That's very limiting and doesn't sound very "interface" like. I have never used JSON before or much XML, so I thought, maybe the JS response should send back raw stuff, like JSON and somehow the page on which the ajax request was called has the instruction on what do to with these raw data. That sounds a lot more flexible, doesn't it? Because look back at that exmpale, what if in the views/locations/index.html.erb, I want to do the exact same thing except I want to put the response in div#project_goes_here and the response should be #{project.name} I know this is a trivial change but that's the point: the RJS only allows one template at a time. So I think the JSON route is the way to go, but how does the already loaded page, the one that the ajax call came from, know when or how to "look forward" to incoming data? I read that PrototypeJS has this template thing, I wouldn't mind using it with JSON, but if you can demonstrate this or other means for displaying received-from-ajax data, I am all attention. Thank You

  • Alternate widgets and logic for ManyToManyField with Django forms

    - by Jaearess
    In my Django project, I have a simple ticket system. When creating a ticket, certain users have the ability to assign the ticket to other users, and to email the ticket to other users as well (this is used as an FYI for those users, so they're aware of the ticket, even though it's not assigned to them.) At the moment, the form for adding a ticket is simply the default Django form, with the "assigned_to" and "email_to" fields being ManyToManyFields, and therefore displayed as MultipleSelect widgets, each with a list of all users. Due to the relatively large number of users, and general awkwardness of the MultipleSelect widget, and alternate layout is now required. The desired layout is a pair of simple Select widgets side-by-side. The first has the option of "Assign to" or "Email to" and the second is a list of the users. Essentially, like this: [Assign to] [John Doe] [Email to] [Jane Roe] [Jack Smith], etc. Of course, since an arbitrary number of users can be assigned or emailed a ticket, there's a simple button that runs some Javascript to add another set of widgets, to allow the user to assign and email as many people as they need to. So far all of that is fairly simple and straight forward. However, the problem I have is using this widget setup/logic setup with Django forms. Instead of lists of users to assign to and email, instead we're getting back pairs of information, one a user and the other which list that user should be placed in. What I'm looking for, but have yet to find, is a way to offload the translation between how the user uses the form, and how Django understands the model to the form itself, so I don't have to manually do the processing of the data before passing it to the form in each place this form is used. Additionally, there's a review screen with the option to go back and change the form before submitting it, so a way to have the form translate both to and from this format would be extremely helpful.

  • Parse numbers in singe textbox for query

    - by Joshua Slocum
    I’ve built a webform in Visual Web Developer Express 2008 to help me with my work. I use a webform to run query requests that are emailed to me. The inputs are in this format 12312 12312 12312 12312 12312 12312 12312 12312 I enter the first number in a textbox and the second number in another textbox and click a button that runs a query and returns the results in a gridview(single row). string strConn, strSQL; strConn = AppConfig.Connection strSQL = 'select fields from table where FirstNum=:FirstNum and SecondNum=:SecondNum'; using (OracleConnection cn = new OracleConnection(strConn)) { OracleCommand cmd = new OracleCommand(strSQL, cn); cmd.Parameters.AddWithValue(":FirstNum", txtFirstNum.Text); cmd.Parameters.AddWithValue(":SeconNum", txtSecondNum.Text); cn.Open(); using (OracleDataReader rdr = cmd.ExecuteReader()) { dgResults.DataSource = rdr; dgResults.DataBind(); } cn.Close(); } I had an idea to help me speed up my work. I’d like to be able to past both numbers in a single textbox ( like this 12312 12312 ) and have the code parse out the nubmers for the query. Or even better would be to past all of them in a multiline textbox like this 12312 12312 12312 12312 12312 12312 12312 12312 And have them all parsed and the query run for each line and the results all output to one gridview. I’m just not sure how to approach this. Any suggestions would be appreciated. Thank you.

  • linux new/delete, malloc/free large memory blocks

    - by brian_mk
    Hi folks, We have a linux system (kubuntu 7.10) that runs a number of CORBA Server processes. The server software uses glibc libraries for memory allocation. The linux PC has 4G physical memory. Swap is disabled for speed reasons. Upon receiving a request to process data, one of the server processes allocates a large data buffer (using the standard C++ operator 'new'). The buffer size varies depening upon a number of parameters but is typically around 1.2G Bytes. It can be up to about 1.9G Bytes. When the request has completed, the buffer is released using 'delete'. This works fine for several consecutive requests that allocate buffers of the same size or if the request allocates a smaller size than the previous. The memory appears to be free'd ok - otherwise buffer allocation attempts would eventually fail after just a couple of requests. In any case, we can see the buffer memory being allocated and freed for each request using tools such as KSysGuard etc. The problem arises when a request requires a buffer larger than the previous. In this case, operator 'new' throws an exception. It's as if the memory that has been free'd from the first allocation cannot be re-allocated even though there is sufficient free physical memory available. If I kill and restart the server process after the first operation, then the second request for a larger buffer size succeeds. i.e. killing the process appears to fully release the freed memory back to the system. Can anyone offer an explanation as to what might be going on here? Could it be some kind of fragmentation or mapping table size issue? I am thinking of replacing new/delete with malloc/free and use mallopt to tune the way the memory is being released to the system. BTW - I'm not sure if it's relevant to our problem, but the server uses Pthreads that get created and destroyed on each processing request. Cheers, Brian.

  • deleted gen folder, eclipse isn't generating it now :(

    - by LuxuryMode
    I accidentally deleted my gen folder and now, predictably, my resources are all messed up. I just created a gen folder myself and tried to project clean - that didn't work. Tried right-clicking project and going to android tools fix project properties - didn't work. Tried unchecking build automatically...didn't work. cleaned, closed project, closed eclipse, restarted, etc, etc. Nothing is working and I keep seeing this error: gen already exists but is not a source folder. Convert to a source folder or rename it. EDIT - OK was able to generate R.java, but now I'm getting crazy stuff in the console: [2011-06-14 17:06:11 - fastapp] Conversion to Dalvik format failed with error 1 [2011-06-14 17:06:42 - fastapp] Dx trouble processing "java/awt/font/NumericShaper.class": Ill-advised or mistaken usage of a core class (java.* or javax.*) when not building a core library. This is often due to inadvertently including a core library file in your application's project, when using an IDE (such as Eclipse). If you are sure you're not intentionally defining a core class, then this is the most likely explanation of what's going on. However, you might actually be trying to define a class in a core namespace, the source of which you may have taken, for example, from a non-Android virtual machine project. This will most assuredly not work. At a minimum, it jeopardizes the compatibility of your app with future versions of the platform. It is also often of questionable legality. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine distribution, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message. If you go ahead and use "--core-library" but are in fact building an application, then be forewarned that your application will still fail to build or run, at some point. Please be prepared for angry customers who find, for example, that your application ceases to function once they upgrade their operating system. You will be to blame for this problem. If you are legitimately using some code that happens to be in a core package, then the easiest safe alternative you have is to repackage that code. That is, move the classes in question into your own package namespace. This means that they will never be in conflict with core system classes. JarJar is a tool that may help you in this endeavor. If you find that you cannot do this, then that is an indication that the path you are on will ultimately lead to pain, suffering, grief, and lamentation.

  • R: Why does read.table stop reading a file?

    - by Mike Dewar
    I have a file, called genes.txt, which I'd like to become a data.frame. It's got a lot of lines, each line has three, tab delimited fields: mike$ wc -l genes.txt 42476 genes.txt I'd like to read this file into a data.frame in R. I use the command read.table, like this: genes = read.table( genes_file, sep="\t", na.strings="-", fill=TRUE, col.names=c("GeneSymbol","synonyms","description") ) Which seems to work fine, where genes_file points at genes.txt. However, the number of lines in my data.frame is significantly less than the number of lines in my text file: > nrow(genes) [1] 27896 and things I can find in the text file: mike$ grep "SELL" genes.txt SELL CD62L|LAM1|LECAM1|LEU8|LNHR|LSEL|LYAM1|PLNHR|TQ1 selectin L don't seem to be in the data.frame > grep("SELL",genes$GeneSymbol) integer(0) it turns out that genes = read.delim( genes_file, header=FALSE, na.strings="-", fill=TRUE, col.names=c("GeneSymbol","synonyms","description"), ) works just fine. Why does read.delim work when read.table not? If it's of use, you can recreate genes.txt using the following commands which you should run from a command line curl -O ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/gene_info.gz gzip -cd gene_info.gz | awk -Ft '$1==9606{print $3 "\t" $5 "\t" $9}' > genes.txt be warned, though, that gene_info.gz is 101MBish.
