  • Problem with stack based implementation of function 0x42 of int 0x13

    - by IceCoder
    I'm trying a new approach to int 0x13 (just to learn more about the way the system works): using stack to create a DAP.. Assuming that DL contains the disk number, AX contains the address of the bootable entry in PT, DS is updated to the right segment and the stack is correctly set, this is the code: push DWORD 0x00000000 add ax, 0x0008 mov si, ax push DWORD [ds:(si)] push DWORD 0x00007c00 push WORD 0x0001 push WORD 0x0010 push ss pop ds mov si, sp mov sp, bp mov ah, 0x42 int 0x13 As you can see: I push the dap structure onto the stack, update DS:SI in order to point to it, DL is already set, then set AX to 0x42 and call int 0x13 the result is error 0x01 in AH and obviously CF set. No sectors are transferred. I checked the stack trace endlessly and it is ok, the partition table is ok too.. I cannot figure out what I'm missing... This is the stack trace portion of the disk address packet: 0x000079ea: 10 00 adc %al,(%bx,%si) 0x000079ec: 01 00 add %ax,(%bx,%si) 0x000079ee: 00 7c 00 add %bh,0x0(%si) 0x000079f1: 00 00 add %al,(%bx,%si) 0x000079f3: 08 00 or %al,(%bx,%si) 0x000079f5: 00 00 add %al,(%bx,%si) 0x000079f7: 00 00 add %al,(%bx,%si) 0x000079f9: 00 a0 07 be add %ah,-0x41f9(%bx,%si) I'm using qemu latest version and trying to read from hard drive (0x80), have also tried with a 4bytes alignment for the structure with the same result (CF 1 AH 0x01), the extensions are present.

  • geo-indexing: efficiently calculating proximity based on latitude/longitude

    - by AnC
    My simple web app (WSGI, Python) supports text queries to find items in the database. Now I'd like to extend this to allow for queries like "find all items within 1 mile of {lat,long}". Of course that's a complex job if efficiency is a concern, so I'm thinking of a dedicated external module that does indexing for geo-coordinates - sort of like Lucene would for text. I assume a generic component like this already exists, but haven't been able to find anything so far. Any help would be greatly appreciated.

  • Make an iPhone InfoButton light/dark based on color behind it

    - by Paula
    How do I detect what color is under the InfoButton... so I can change the button from DARK to LIGHT? I set my view's color... but how do I tell if it's "kind of light" or "kind of dark"? Besides... I can't change the info-button from light to dark anyway. (read only) Ugh. Shouldn't Apple have some kind of a simple "cmdButton.doThisExtremelyCommonThingForMe = TRUE" statement? InfoButtons are useless if you can't even see them. (Or how would I put an image behind the button to make it stand-out more?)

  • Replace values in a dataframe based on another factor which contains NA's in R

    - by PaulHurleyuk
    I have a dataframe which contains (among other things) a numeric column with a concentration, and a factor column with a status flag. This status flag contains NA's. Here's an example df<-structure(list(conc = c(101.769, 1.734, 62.944, 92.697, 25.091, 27.377, 24.343, 55.084, 0.335, 23.280), status = structure(c(NA, NA, NA, NA, NA, NA, 2L, NA, 1L, NA), .Label = c("<LLOQ", "NR"), class = "factor")), .Names = c("conc", "status"), row.names = c(NA, -10L), class = "data.frame") I want to replace the concentration column with a string for some values of the flag column, or with the concentration value formatted to a certain number of significant digits. When I try this ifelse(df$status=="NR","NR",df$conc) The NA's in the status flag don't trigger either the true or false condition (and return NA) - as the documentation suggests it will. I could loop over the rows and use IF then else on each one but this seems inefficient. Am I missing something ? I've tried as.character(df$status) as well which doesn't work. My mojo must be getting low....

  • jqGrid - how to change title based on colModel sortable property

    - by Greg
    When the mouse hovers over each column I'd like the tooltip to indicate whether that column is sortable. I am able to change the title attribute with something like this: $("#List .ui-th-column").each(function(i) { var isSortable = i % 2; $(this).attr('title', isSortable ? "Not Sortable" : "Click header to sort."); }); I'd like to replace the demo expression 'i % 2' with a check of the colMode's sortable property, but I can't figure out how to get the value of the colModel's sortable property. colModel: [ { name: 'Name', index: 'Name', width: 100, sortable: true }, { name: 'Note', index: 'Note', width: 200, sortable: false } ] I've tried .getGridParam and .getColProp but I don't think the syntax I'm using is correct.

  • Fork or copy a users browser session in IE

    - by jmoeller
    Is it possible to fork a users session (or do something similar) in a Internet Explorer plugin? I want to process the page the user is on when they click a button in the toolbar. To avoid interrupting the users browsing, I'd like to "copy" everything so I can parse and process the page in the background. The processing can involve things such as loading the content of the result links on a Google search, if that's where the button was clicked. So - what I basically want is to imitate "Ctrl+N" but hide the window from the user, so they won't be interrupted. As you can see, if you fill out and submit the form on http://www.snee.com/xml/crud/posttest.html and press "Ctrl+N", everything posted will still appear in the new window, but it won't post the data twice. I was thinking of somehow copying the IWebBrowser2, but: I'm not sure if that's possible (I haven't been able to find any information on MSDN) I don't know if it copies the sessions as well. Creating a new instance of the IWebBrowser2 and simply navigating to the current URL isn't a valid solution as POST-variables of course doesn't get carried over.

  • Does UIWebView support javascript-based double-click events?

    - by Eric
    As usual, I'm trying to do something the easiest way possible, in this case implement a double-tap handler on a UIWebView like so: <div id="foo" ondblclick="clickHandler(this);" ... > It works fine in Safari and Firefox, and I know the code containing clickHandler is loading on the iPhone thanks to a now-annoying alert stmt at the end of loading. If I change ondblclick to onclick it works on both the device and the simulator. From reading similar queries it would seem that I need to intercept the taps in ... and then run my JavaScript code with the stringByEvaluatingJavaScriptFromString method, but then how do I know the JS id of the target? I no like that, would rather write a pure HTML/DOM/JS solution. Or since my app is about 80% web content, should I be using phonegap instead?

  • SQL Stored Queries - use result of query as boolean based on existence of records

    - by Christian Mann
    Just getting into SQL stored queries right now... anyway, here's my database schema (simplified for YOUR convenience): member ------ id INT PK board ------ id INT PK officer ------ id INT PK If you're into OOP, Officer Inherits Board Inherits Member. In other words, if someone is listed on the officer table, s/he is listed on the board table and the member table. I want to find out the highest privilege level someone has. So far my SP looks like this: DELIMITER // CREATE PROCEDURE GetAuthLevel(IN targetID MEDIUMINT) BEGIN IF SELECT `id` FROM `member` WHERE `id` = targetID; THEN IF SELECT `id` FROM `board` WHERE `id` = targetID; THEN IF SELECT `id` FROM `officer` WHERE `id` = targetID; THEN RETURN 3; /*officer*/ ELSE RETURN 2; /*board member*/ ELSE RETURN 1; /*general member*/ ELSE RETURN 0; /*not a member*/ END // DELIMITER ; The exact text of the error is #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT id FROM member WHERE id = targetID; THEN IF SEL' at line 4 I suspect the issue is in the arguments for the IF blocks. What I want to do is return true if the result-set is at least one -- i.e. the id was found in the table. Do any of you guys see anything to do here, or should I reconsider my database design into this:? person ------ id INT PK level SMALLINT

  • update variable based upon results from .NET backgroundworker

    - by Bruce
    I've got a C# program that talks to an instrument (spectrum analyzer) over a network. I need to be able to change a large number of parameters in the instrument and read them back into my program. I want to use backgroundworker to do the actual talking to the instrument so that UI performance doesn't suffer. The way this works is - 1) send command to the instrument with new parameter value, 2) read parameter back from the instrument so I can see what actually happened (for example, I try to set the center frequency above the max that the instrument will handle and it tells me what it will actually handle), and 3) update a program variable with the actual value received from the instrument. Because there are quite a few parameters to be updated I'd like to use a generic routine. The part I can't seem to get my brain around is updating the variable in my code with what comes back from the instrument via backgroundworker. If I used a separate RunWorkerCompleted event for each parameter I could hardwire the update directly to the variable. I'd like to come up with a way of using a single routine that's capable of updating any of the variables. All I can come up with is passing a reference number (different for each parameter) and using a switch statement in the RunWorkerCompleted handler to direct the result. There has to be a better way.

  • Lightweight PHP5 based template class/system

    - by Wizzard
    Hi there. Looking at using a template system for a new project, it's only a small site and don't want to use the overhead and 'complexity' of smarty. I don't really like template systems that force you to make use of another language just to make it easier for designers (apparently). Something like this http://www.namepros.com/code/517342-php5-template-class.html is what Im looking at but something which is a bit more robust and proven.

  • Change value of jquery variable based on a select box

    - by Nikos
    I have a jquery datepicker script and what I want to do is to change "minDate: 10" value by a select box. $(function() { $('#hotel').change(function() { // assign the value to a variable, so you can test to see if it is working var selectVal = $('#hotel :selected').val(); if( selectVal == "hotel_c" ) { var date = 10; } if( selectVal == "hotel_a" ) { var date = 15; } if( selectVal == "hotel_b" ) { var date = 6; } }); var dates = $('#from, #to').datepicker({ defaultDate: "+1w", changeMonth: true, dateFormat: 'yy-m-d', minDate: 10, numberOfMonths: 3, onSelect: function(selectedDate) { var option = this.id == "from" ? "minDate" : "maxDate"; var instance = $(this).data("datepicker"); var date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings); dates.not(this).datepicker("option", option, date); } }); });

  • Enabling browser caching via java

    - by Franz See
    Good day, I am using CacheFilter to filter a certain path to my server (which outputs an image stream to the response stream). And I've configured it in my web.xml as follows: <filter> <filter-name>imagesCache</filter-name> <filter-class>com.samaxes.cachefilter.presentation.CacheFilter</filter-class> <init-param> <param-name>privacy</param-name> <param-value>public</param-value> </init-param> <init-param> <param-name>expirationTime</param-name> <param-value>2592000</param-value> </init-param> </filter> ... <filter-mapping> <filter-name>imagesCache</filter-name> <url-pattern>/my/path/*</url-pattern> </filter-mapping> Using my firefox, if I access my url via the address bar, it hits the server the first time but uses the cache during succeeding calls. However, if the url is inside my page ( i.e. <img src="..."/> ), it seems to hit the server all the time. [EDIT] After a few more testing, accessing my image via the address bar does not work all the time. But caching does seem to work more often with it than . As to whether it really, I am not sure. Additional Info: my path is something like /my/path?then=some&query=strings. Notice that it doesn't have an extension (i.e. gif, png, jpeg ) but it's mimetype is set properly ( image/gif, image/png, image/jpeg ). I am not sure if the lack of extension or the presence of the query strings have any impact. (Also, another note. though my url have query strings, I am using the same uri + query string over and over again with my tests). Any ideas why? Thanks

  • How can I block based on URL (from address bar) in a safari extension

    - by PerilousApricot
    I'm trying to write an extension that will block access to (configurable) list of URLs if they are accessed more than N times per hour. From what I understand, I need to have a start script pass a "should I load this" message to a global HTML page (who can access the settings object to get the list of URLs), who will give a thumbs up/thumbs down message back to the start script to deny/allow loading. That works out fine for me, but when I use the usual beforeLoad/canLoad handlers, I get messages for all the sub-items that need to be loaded (images/etc..), which screws up the #accesses/hour limit I'm trying to make. Is there a way to synchronously pass messages back and forth between the two sandboxes so I can tell the global HTML page, "this is the URL in the window bar and the timestamp for when this request came in", so I can limit duplicate requests? Thanks!

  • WPF Visibility of a UI element based on combo selection

  • Restricting dynamically loaded classes and jars based on a security policy

    - by Max
    Hi, I would like to dynamically load a set of jars or classes (i.e. plugins loaded at runtime). At the same time, I would like to restrict what these plugins are able to do in the JVM. For a test case, I would like to restrict them to pretty much everything (right now I'm just allowing one System.getProperty value to be read). I am currently using a security policy file, but I'm having difficulty specifying a policy for one folder or package in my codeBase, but not another. Here is how my policy looks now: grant codeBase "file:/home/max/programming/java/plugin/plugins/" { permission java.util.PropertyPermission "java.version", "read"; }; grant codeBase "file:/home/max/programming/java/plugin/api/" { permission java.security.AllPermission; }; Where (for testing purposes), all files in the plugins package and folder are restricted, but the classes in the api folder are not. Is this possible? Do I have to create a custom class loader? Is there a better way to go about doing this? Thanks.

  • NoSQL DB for .Net document-based database (ECM)

    - by Dane
    I'm halfway through coding a basic multi-tenant SaaS ECM solution. Each client has it's own instance of the database / datastore, but the .Net app is single instance. The documents are pretty much read only (i.e. an image archive of tiffs or PDFs) I've used MSSQL so far, but then started thinking this might be viable in a NoSQL DB (e.g. MongoDB, CouchDB). The basic premise is that it stores documents, each with their own particular indexes. Each tenant can have multiple document types. e.g. One tenant might have an invoice type, which has Customer ID, Invoice Number and Invoice Date. Another tenant might have an application form, which has Member Number, Application Number, Member Name, and Application Date. So far I've used the old method which Sharepoint (used?) to use, and created a document table which has int_field_1, int_field_2, date_field_1, date_field_2, etc. Then, I've got a "mapping" table which stores the customer specific index name, and the database field that will map to. I've avoided the key-value pair model in the DB due to volume of documents. This way, we can support multiple document types in the one table, and get reasonably high performance out of it, and allow for custom document type searches (i.e. user selects a document type, then they're presented with a list of search fields). However, a NoSQL DB might make this a lot simpler, as I don't need to worry about denormalizing the document. However, I've just got concerns about the rest of the data around a document. We store an "action history" against the document. This tracks views, whether someone emails the document from within the system, and other "future" functionality (e.g. faxing). We have control over the document load process, so we can manipulate the data however it needs to be to get it in the document store (e.g. assign unique IDs). Users will not be adding in their own documents, so we shouldn't need to worry about ACID compliance, as the documents are relatively static. So, my questions I guess : Is a NoSQL DB a good fit Is MongoDB the best for Asp.Net (I saw Raven and Velocity, but they're still kinda beta) Can I store a key for each document, and then store the action history in a MSSQL DB with this key? I don't need to do joins, it would be if a person clicks "View History" against a document. How would performance compare between the two (NoSQL DB vs denormalized "document" table) Volumes would be up to 200,000 new documents per month for a single tenant. My current scaling plan with the SQL DB involves moving the SQL DB into a cluster when certain thresholds are reached, and then reviewing partitioning and indexing structures.

  • Network communication for a turn based board game

    - by randooom
    Hi all, my first question here, so please don't be to harsh if something went wrong :) I'm currently a CS student (from Germany, if this info is of any use ;) ) and we got a, free selectable, programming assignment, which we have to write in a C++/CLI Windows Forms Application. My team, two others and me, decided to go for a network-compatible port of the board game Risk. We divided the work in 3 Parts, namely UI, game logic and network. Now we're on the part where we have to get everything working together and the big question mark is, how to get the clients synchronized with each other? Our approach so far is, that each client has all information necessary to calculate and/or execute all possible actions. Actually the clients have all information available at all, aside from the game-initializing phase (add players, select map, etc.), which needs one "super-client" with some extra stuff to control things. This is the standard scenario of our approach: player performs action, the action is valid and got executed on the players client action is sent over the network action is executed on the other clients The design (i.e. no or code so far) we came up with so far, is something like the following pseudo sequence diagram. Gui, Controller and Network implement all possible actions (i.e. all actions which change data) as methods from an interface. So each part can implement the method in a way to get their job done. Example with Action(): On the player side's Client: Player-->Gui.Action() Gui-->Controller.Action() Controller-->Logic.Action (Logic.Action() == NoError)? Controller-->Network.Action() Network-->Parser.ParseAction() Network.Send(msg) On all other clients: Network.Recv(msg) Network-->Parser.Deparse(msg) Parser-->Logic.Action() Logic-->Gui.Action() The questions: Is this a viable approach to our task? Any better/easier way to this? Recommendations, critique? Our knowledge (so you can better target your answer): We are on the beginner side, in regards to programming on a somewhat larger projects with a small team. All of us have some general programming experience and basic understanding of the .Net Libraries and Windows Forms. If you need any further information, please feel free to ask.
