  • Unicode strings in my C# App are shown with question marks

    - by mrbamboo
    Hi, I have a header file in C++/CLR project, which contains some strings in different languages. arabic, english, german, chinese, french, japanese etc... I have a second project written in C#. Here I access the strings stored in the header file of the C++/CLR project. The encoding of the header file is Unicode - Codepage 1200 or UTF-8. the visual studio editor is able to display the strings correctly. At runtime I access these strings and assign them into a local String variable. Here I recognized that many strings are not shown correctly. Doesn't matter if I assign them or not. Accessing the original place (while debugging) shows me all the foreign strings with question marks. Especially chinese, just question marks. Example : "So?e St?ange ?ext in Ch?n?se" (This is not the best example, I know) What is the problem? I read that C# is by default UTF-16, My header file containing the strings is UTF-16 or UTF-8. I must be able to handle strings in different languages. What am I doing wrong?

  • Beginner SQL question: querying gold and silver tag badges in Stack Exchange Data Explorer

    - by polygenelubricants
    I'm using the Stack Exchange Data Explorer to learn SQL, but I think the fundamentals of the question is applicable to other databases. I'm trying to query the Badges table, which according to Stexdex (that's what I'm going to call it from now on) has the following schema: Badges Id UserId Name Date This works well for badges like [Epic] and [Legendary] which have unique names, but the silver and gold tag-specific badges seems to be mixed in together by having the same exact name. Here's an example query I wrote for [mysql] tag: SELECT UserId as [User Link], Date FROM Badges Where Name = 'mysql' Order By Date ASC The (slightly annotated) output is: as seen on stexdex: User Link Date --------------- ------------------- // all for silver except where noted Bill Karwin 2009-02-20 11:00:25 Quassnoi 2009-06-01 10:00:16 Greg 2009-10-22 10:00:25 Quassnoi 2009-10-31 10:00:24 // for gold Bill Karwin 2009-11-23 11:00:30 // for gold cletus 2010-01-01 11:00:23 OMG Ponies 2010-01-03 11:00:48 Pascal MARTIN 2010-02-17 11:00:29 Mark Byers 2010-04-07 10:00:35 Daniel Vassallo 2010-05-14 10:00:38 This is consistent with the current list of silver and gold earners at the moment of this writing, but to speak in more timeless terms, as of the end of May 2010 only 2 users have earned the gold [mysql] tag: Quassnoi and Bill Karwin, as evidenced in the above result by their names being the only ones that appear twice. So this is the way I understand it: The first time an Id appears (in chronological order) is for the silver badge The second time is for the gold Now, the above result mixes the silver and gold entries together. My questions are: Is this a typical design, or are there much friendlier schema/normalization/whatever you call it? In the current design, how would you query the silver and gold badges separately? GROUP BY Id and picking the min/max or first/second by the Date somehow? How can you write a query that lists all the silver badges first then all the gold badges next? Imagine also that the "real" query may be more complicated, i.e. not just listing by date. How would you write it so that it doesn't have too many repetition between the silver and gold subqueries? Is it perhaps more typical to do two totally separate queries instead? What is this idiom called? A row "partitioning" query to put them into "buckets" or something?

  • Mocking inter-method dependencies

    - by Zecrates
    I've recently started using mock objects in my tests, but I'm still very inexperienced with them and unsure of how to use them in some cases. At the moment I'm struggling with how to mock inter-method dependencies (calling method A has an effect on the results of method B), and whether it should even be mocked (in the sense of using a mocking framework) at all? Take for example a Java Iterator? It is easy enough to mock the next() call to return the correct values, but how do I mock hasNext(), which depends on how many times next() has been called? Currently I'm using a List.Iterator as I could find no way to properly mock one. Does Martin Fowler's distinction between mocks and stubs come into play here? Should I rather write my own IteratorMock? Also consider the following example. The method to be tested calls mockObject.setX() and later on mockObject.getX(). Is there any way that I can create such a mock (without writing my own) which will allow the returned value of getX to depend on what was passed to setX?

  • RSS feed created with PHP only shows the title in the feed reader

    - by James Simpson
    I am using the following PHP code to generate the XML for an RSS feed, but it doesn't seem to be working correctly. No short description is displayed in the feed reader, all I see is the title of the article. Also, all of the articles say they were published at the same time. This is the first time I have tried to setup an RSS feed, so I'm sure I've made several stupid mistakes. $result = mysql_query("SELECT * FROM blog ORDER BY id DESC LIMIT 10"); $date = date(DATE_RFC822); header('Content-type: text/xml'); echo ("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"); echo ("<rss version=\"2.0\">\n"); echo ("<channel>\n"); echo ("<lastBuildDate>$date</lastBuildDate>\n"); echo ("<pubDate>$date</pubDate>\n"); echo ("<title>my website name</title>\n"); echo ("<description><![CDATA[the description]]></description>\n"); echo ("<link>http://my-domain.com</link>\n"); echo ("<language>en</language>\n"); $ch=100; while ($a = mysql_fetch_array($result)) { $headline = htmlentities(stripslashes($a['subject'])); $posturl = $a[perm_link]; $content = $a['post']; $date = date(DATE_RFC822, $a['posted']); echo ("<item>\n"); echo ("<title>$headline</title>\n"); echo ("<link>$posturl</link>\n"); echo ("<description><![CDATA[$content]]></description>\n"); echo ("<guid isPermaLink=\"true\">$posturl</guid>\n"); echo ("<pubDate>$date2</pubDate>\n"); echo ("</item>\n"); } echo ("</channel>\n"); echo ("</rss>\n");

  • how to: dynamically load google ajax api into chrome extension content script

    - by Hoff
    Hi there, I'm trying to make use of google's ajax apis in a chorme extension's "content script". On a regular html page, I would just do this: <script src="http://www.google.com/jsapi"></script> <script> google.load("language", "1"); </script> But since I'm trying to load the tranlation library dynamically from js code, I've tried: script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.type = "text/javascript"; document.getElementsByTagName("head")[0].appendChild(script); google.load('language','1') but the last line throws the following error: Uncaught TypeError: Object # has no method 'load' Funny enough, when i enter the same "google.load('language','1')" in chrome's js console, it works as intended... I've also tried with jquery's .getScript() but the same problem persists... Does anybody have any clue what might be the problem and how it could be solved? Many thanks in advance! Martin

  • Career Plan: The one year plan. The three year plan.

    - by drelihan
    Hi Folks, I work as a developer however I only recently began developing full time having worked for 5 years in various roles. When it comes to career planning I think I pretty much agree with The Journeyman to Craftsman model coined in The Pragmatic Probrammer and used by Bob Martin. I see myself as a journeyman and I won't call myself a "good" (for want of a better word) until I re-evaluate my skills in 5 years time. However, as part of our careers we are encouraged to make one and three year plan with specific goals that we should hit. Unfortunately, my goal is this: Write clean code that solves a problem and is easy to maintain. From a technology point of view I want to know C++ and .net programming inside out(C#, WCF etc..) But that's it. That's my plan. Is this enough? So although there's a great discussion on what people should do with their career: http://stackoverflow.com/questions/11313/career-planning-any-tips My question is this: What's your one year plan? What's your three year plan? And am I being naive with my career? Thanks,

  • ClassCastException while using service

    - by Sebi
    I defined a local Service: public class ComService extends Service implements IComService { private IBinder binder = new ComServiceBinder(); public class ComServiceBinder extends Binder implements IComService.IServiceBinder { public IComService getService() { return ComService.this; } } public void test(String msg) { System.out.println(msg); } @Override public IBinder onBind(Intent intent) { return binder; } } The corresponding interface: public interface IComService { public void test(String msg); public interface IServiceBinder { IComService getService(); } } Then i try to bind the service in another activity in another application, where the same interface is available: bindService(new Intent("ch.ifi.csg.games4blue.gamebase.api.ComService"), conn, Context.BIND_AUTO_CREATE); and private ServiceConnection conn = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { Log.i("INFO", "Service bound " + name); comService = ((IComService.IServiceBinder)service).getService(); serviceHandler.sendEmptyMessage(0); } @Override public void onServiceDisconnected(ComponentName arg0) { Log.i("INFO", "Service Unbound "); } }; but the line comService = ((IComService.IServiceBinder)service).getService(); always throws a 05-02 22:12:55.922: ERROR/AndroidRuntime(622): java.lang.ClassCastException: android.os.BinderProxy I can't explain why, I followed the app sample on http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/LocalServiceBinding.html Any hints would be nice!

  • Switching AM/PM in ASP.NET AJAX MaskedEdit localization

    - by Greg
    The sample page for the MaskedEdit says "Tip: Type 'A' or 'P' to switch AM/PM". Are these keys hardcoded? Does the control automatically change itself for cultures that use 12-hour designators that don't start with A or P? Or is just broken for those? example: Arabic (Saudi Arabia) - AM: ? Arabic (Saudi Arabia) - PM: ? Chinese (Taiwan) - AM: ?? Chinese (Taiwan) - PM: ?? Greek (Greece) - AM: pµ Greek (Greece) - PM: µµ Korean (Korea) - AM: ?? Korean (Korea) - PM: ?? Albanian (Albania) - AM: PD Albanian (Albania) - PM: MD Persian (Iran) - AM: ?.? Persian (Iran) - PM: ?.? Vietnamese (Vietnam) - AM: SA Vietnamese (Vietnam) - PM: CH Afrikaans (South Africa) - PM: nm Punjabi (India) - AM: ????? Punjabi (India) - PM: ??? Syriac (Syria) - AM: ?.? Syriac (Syria) - PM: ?.? If this control doesn't handle this situation, does anyone know of a control that does?

  • how can I speed up insertion of many rows to a table via ADO.NET?

    - by jcollum
    I have a table that has 5 columns: AcctId (int), Address1 (varchar), Address2 (varchar), Person1 (varchar), Person2 (varchar) . I'm generating random data to insert into this table via a C# console application. I've tried doing this random data insert via SQL-Server and decided it was not a good solution -- SQL is not good at random on an each-row basis. Generating the random data -- 975k rows of it -- takes a minimal amount of time. It's in a List of custom objects. I need to take this random data and update many rows in the database with the new random data. I tried updating the rows one at a time, very slow because of the repeated searching of the List object in code. So I think the best approach is to put all the randomized data into a table in the database, then update all the other tables that use this data. I.e. UPDATE t SET t.Address1=d.Address1 FROM Table1 t INNER JOIN RandomizedData d ON d.AcctId = t.Acct_ID. The database is very un-normalized so this Acct data is sprinkled all over the place. I've got no control of the normalization. So, having decided to insert all of the randomized data into a single table, I set out to create insert scripts: USE TheDatabase Insert tmp_RandomizedData SELECT 1,'4392 EIGHTH AVE','','JENNIFER CARTER','BARBARA CARTER' UNION ALL SELECT 2,'2168 MAIN ST','HNGR F','DANIEL HERNANDEZ','SUSAN MARTIN' // etc another 98 times... // FYI, this is not real data! I'm building this INSERT script in batches of 100. It's taking on average 175 ms to run each insert. Does this seem like a long time? It's going to take about 35 mins to run the whole insert. The table doesn't have a primary key or any indexes. I was planning on adding those after all the data in inserted (thinking that that would be faster). Is there a better way to do this?

  • Overlay SVG diagrams on google maps

    - by ThibThib
    Hello I would like to add an overlay image on a google map. This image is a SVG file I have generated (python with svgfig). I am using the following code if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(48.8, 2.4), 12);     // ground overlay     var boundaries = new GLatLngBounds(new GLatLng(48.283188032632829, 1.9675270369830129), new GLatLng(49.187215000000002, 2.7771877478303999));     var oldmap = new GGroundOverlay("test.svg", boundaries); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.addOverlay(oldmap); } Surprisingly, it works with Safari 4, but it doesn't with Firefox (with Safari 3, the background is not transparent) Does anyone has an idea on how I could overlay a SVG ? Thanks PS1: I read some works like this or the source code of swa.ethz.ch/googlemaps, but it seems that they have to use javascript code to parse the SVG and add one by one all the elements (but I did not understood all the source...) PS2: The SVG is composed of different filled paths and circles, with transparency. If there is no solution to overlay my SVG, I can use 2 alternative solutions: rasterize the SVG convert the paths and circles in GPolygons But, I do not really like the 1st solution because of the poor quality of the bitmap and the time to generate it with antialiasing. And for the 2nd solutions, the arcs, ellipses and circles will have to be decomposed into small polylines. A lot of them will be necessary for a good result. But I have around 3000 arcs and circles to draw, so...

  • Patterns for non-layered applications

    - by Paul Stovell
    In Patterns of Enterprise Application Architecture, Martin Fowler writes: This book is thus about how you decompose an enterprise application into layers and how those layers work together. Most nontrivial enterprise applications use a layered architecture of some form, but in some situations other approaches, such as pipes and filters, are valuable. I don't go into those situations, focussing instead on the context of a layered architecture because it's the most widely useful. What patterns exist for building non-layered applications/parts of an application? Take a statistical modelling engine for a financial institution. There might be a layer for data access, but I expect that most of the code would be in a single layer. Would you still expect to see Gang of Four patterns in such a layer? How about a domain model? Would you use OO at all, or would it be purely functional? The quote mentions pipes and filters as alternate models to layers. I can easily imagine a such an engine using pipes as a way to break down the data processing. What other patterns exist? Are there common patterns for areas like task scheduling, results aggregation, or work distribution? What are some alternatives to MapReduce?

  • PHP Uploadprogress extension function always returning null, with no upload data.

    - by abhinavlal
    I am using php 5.3.2 with uploadprogress extension to get a progressbar during upload using zend framework. Even the demo provided with zend is not working. code in zend example - if (isset($_GET['uploadId'])) { set_include_path(realpath(dirname(__FILE__) . '/../../../library') . PATH_SEPARATOR . get_include_path()); require_once 'Zend/ProgressBar.php'; require_once 'Zend/ProgressBar/Adapter/JsPull.php'; require_once 'Zend/Session/Namespace.php'; $data = uploadprogress_get_info($_GET['uploadId']); $bytesTotal = ($data === null ? 0 : $data['bytes_total']); $bytesUploaded = ($data === null ? 0 : $data['bytes_uploaded']); $adapter = new Zend_ProgressBar_Adapter_JsPull(); $progressBar = new Zend_ProgressBar($adapter, 0, $bytesTotal, 'uploadProgress'); if ($bytesTotal === $bytesUploaded) { $progressBar->finish(); } else { $progressBar->update($bytesUploaded); } } uploadprogress_get_info always returns null. I thought something is wrong with my code so i downloaded the working sample available at http://labs.liip.ch/uploadprogresssimple/index.php but even in that case in uploadprogress_get_info always return null. My uploadprogress config values uploadprogress support enabled Version 1.0.1 uploadprogress.file.contents_template /tmp/upload_contents_%s uploadprogress.file.filename_template /tmp/upt_%s.txt uploadprogress.get_contents 1 While googling around i found uploadprogress extension has some issue with Suhosin Patch < 0.9.26 but i am using Suhosin Patch 0.9.9.1

  • 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.

  • PHP: Aggregate Model Classes or Uber Model Classes?

    - by sunwukung
    In many of the discussions regarding the M in MVC, (sidestepping ORM controversies for a moment), I commonly see Model classes described as object representations of table data (be that an Active Record, Table Gateway, Row Gateway or Domain Model/Mapper). Martin Fowler warns against the development of an anemic domain model, i.e. a class that is nothing more than a wrapper for CRUD functionality. I've been working on an MVC application for a couple of months now. The DBAL in the application I'm working on started out simple (on account of my understanding - oh the benefits of hindsight), and is organised so that Controllers invoke Business Logic classes, that in turn access the database via DAO/Transaction Scripts pertinent to the task at hand. There are a few "Entity" classes that aggregate these DAO objects to provide a convenient CRUD wrapper, but also embody some of the "behaviour" of that Domain concept (for example, a user - since it's easy to isolate). Taking a look at some of the code, and thinking along refactoring some of the code into a Rich Domain Model, it occurred to me that were I to try and wrap the CRUD routines and behaviour of say, a Company into a single "Model" class, that would be a sizeable class. So, my question is this: do Models represent domain objects, business logic, service layers, all of the above combined? How do you go about defining the responsibilities for these components?

  • AVAudioPlayer problem regarding song overlaping in iPhone

  • C# connect to domain SQL Server 2005 from non-domain machine

    - by user304582
    Hi, I asked a question a few days ago (http://stackoverflow.com/questions/2795723/access-to-sql-server-2005-from-a-non-domain-machine-using-windows-authentication) which got some interesting, but not usable suggestions. I'd like to ask the question again, but make clear what my constraints are: I have a Windows domain within which a machine is running SQL Server 2005 and which is configured to support only Windows authentication. I would like to run a C# client application on a machine on the same network, but which is NOT on the domain, and access a database on the SQL Server 2005 instance. I CANNOT create or modify OS or SQL Server users on either machine, and I CANNOT make any changes to permissions or impersonation, and I CANNOT make use of runas. I know that I can write Perl and Java applications that can connect to the SQL Server database using only these four parameters: server name, database name, username (in the form domain\user), and password. In C# I have tried various things around: string connectionString = "Data Source=server;Initial Catalog=database;User Id=domain\user;Password=password"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); and tried setting integrated security to true and false, but nothing seems to work. Is what I am trying to do simply impossible in C#? Thanks for any help, Martin

  • Which tools to use and how to find file descriptors leaking from Glassfish?

    - by cclark
    We release new code to production every week and Glassfish hasn't had any problems. This weekend we had to move racks at our hosting provider. There were not any code changes (they just powered off, moved, re-racked and powered on) but we're on a new network infrastructure and suddenly we're leaking file descriptors like a sieve. So I'm guessing there is some sort of connection attempting to be made which now fails due to a network change. I'm running Glassfish v2ur2-b04/AS9.1_02 on RHEL4 with an embedded IMQ instance. After the move I started seeing: [#|2010-04-25T05:34:02.783+0000|SEVERE|sun-appserver9.1|javax.enterprise.system.container.web|_ThreadID=33;_ThreadName=SelectorThread-?4848;_RequestID=c4de6f6d-c1d6-416d-ac6e-49750b1a36ff;|WEB0756: Caught exception during HTTP processing. java.io.IOException: Too many open files at sun.nio.ch.ServerSocketChannelImpl.accept0(Native Method) ...

I have no idea what these sockets are. I've undeployed my application so there is only a plain Glassfish instance running and I still see it leaking 12 file descriptors a minute. So I think this leak is in Glassfish or potentially IMQ. What approach should I take to tracking down these sockets of unknown protocol? What tools can I use (or flags can I pass to lsof) to get more information about where to look? thanks, chuck

  • Display pdf file inline in Rails app

    - by Martas
    Hi, I have a pdf file attachment saved in the cloud. The file is attached using attachment_fu. All I do to display it in the view is: <%= image_tag @model.pdf_attachment.public_filename %> When I load the page with this code in the browser, it does what I want: it displays the attached pdf file. But only on Mac. On Windows, browsers will display a broken image placeholder. Chrome's Developer Tools report: "Resource interpreted as image but transferred with MIME type application/pdf." I also tried sending the file from controller: in PdfAttachmentController: def send_pdf_attachment pdf_attachment = PdfAttachment.find params[:id] send_file pdf_attachment.public_filename, :type => pdf_attachment.content_type, :file_name => pdf_attachment.filename, :disposition => 'inline' end in routes.rb: map.send_pdf_attachment '/pdf_attachments/send_pdf_attachment/:id', :controller => 'pdf_attachments', :action => 'send_pdf_attachment' and in the view: <%= send_pdf_attachment_path @model.pdf_attachment %> or <%= image_tag( send_pdf_attachment_path @model.pdf_attachment ) %> And that doesn't display the file on Mac (I didn't try on Windows), it displays the path: pdf_attachments/send_pdf_attachment/35 So, my question is: what do I do to properly display a pdf file inline? Thanks martin

  • How Does One Make Scala Control Abstraction in Repeat Until?

    - by peter_pilgrim
    Hi I am Peter Pilgrim. I watched Martin Odersky create a control abstraction in Scala. However I can not yet seem to repeat it inside IntelliJ IDEA 9. Is it the IDE? package demo class Control { def repeatLoop ( body: = Unit ) = new Until( body ) class Until( body: = Unit ) { def until( cond: = Boolean ) { body; val value: Boolean = cond; println("value="+value) if ( value ) repeatLoop(body).until(cond) // if (cond) until(cond) } } def doTest2(): Unit = { var y: Int = 1 println("testing ... repeatUntil() control structure") repeatLoop { println("found y="+y) y = y + 1 } { until ( y < 10 ) } } } The error message reads: Information:Compilation completed with 1 error and 0 warnings Information:1 error Information:0 warnings C:\Users\Peter\IdeaProjects\HelloWord\src\demo\Control.scala Error:Error:line (57)error: Control.this.repeatLoop({ scala.this.Predef.println("found y=".+(y)); y = y.+(1) }) of type Control.this.Until does not take parameters repeatLoop { In the curried function the body can be thought to return an expression (the value of y+1) however the declaration body parameter of repeatUntil clearly says this can be ignored or not? What does the error mean?

    Hello i have a simple program that sorts a text file according to length of words per line this program works without problems in my xp based old machine now i run this program on my new win7/intel core i5 machine, it freezes whole system and back normal after it finishes it's work. i'v invastigated the code and found the line causing the freeze it was this specific line... caption := IntToStr(i) + '..' + IntTostr(ii); i'v changed it to caption := IntTostr(ii); //slow rate change and there is no freeze and then i'v changed it to caption := IntTostr(i); //fast rate change and it freeze again my main complete procedure code is var tword : widestring; i,ii,li : integer; begin tntlistbox1.items.LoadFromFile('d:\new folder\ch.txt'); tntlistbox2.items.LoadFromFile('d:\new folder\uy.txt'); For ii := 15 Downto 1 Do //slow change Begin For I := 0 To TntListBox1.items.Count - 1 Do //very fast change Begin caption := IntToStr(i) + '..' + IntTostr(ii); //problemetic line tword := TntListBox1.items[i]; LI := Length(tword); If lI = ii Then Begin tntlistbox3.items.Add(Trim(tntlistbox1.Items[i])); tntlistbox4.items.Add(Trim(tntlistbox2.Items[i])); End; End; End; end; any idea why ? and how to fix it? i use delphi 2007/win32

  • MS hotfix delayed delivery.

    - by MOE37x3
    I just requested a hotfix from support.microsoft.com and put in my email address, but I haven't received the email yet. The splash page I got after I requested the hotfix said: Hotfix Confirmation We will send these hotfixes to the following e-mail address: (my correct email address) Usually, our hotfix e-mail is delivered to you within five minutes. However, sometimes unforeseen issues in e-mail delivery systems may cause delays. We will send the e-mail from the “[email protected]” e-mail account. If you use an e-mail filter or a SPAM blocker, we recommend that you add “[email protected]” or the “microsoft.com” domain to your safe senders list. (The safe senders list is also known as a whitelist or an approved senders list.) This will help prevent our e-mail from going into your junk e-mail folder or being automatically deleted. I'm sure that the email is not getting caught in a spam catcher. How long does it normally take to get one of these hotfixes? Am I waiting for some human to approve it, or something? Should I just give up and try to get the file I need some other way? (Update: Replaced "[email protected]" with "(my correct email address)" to resolve Martín Marconcini's ambiguity.)

  • NASM - Load code from USB Drive

    - by new123456
    Hola, Would any assembly gurus know the argument (register dl) that signifies the first USB drive? I'm working through a couple of NASM tutorials, and would like to get a physical boot (I can get a clean one with qemu). This is the section of code that loads the "kernel" data from disk: loadkernel: mov si, LMSG ;; 'Loading kernel',13,10,0 call prints ;; ex puts() mov dl, 0x00 ;; The disk to load from mov ah, 0x02 ;; Read operation mov al, 0x01 ;; Sectors to read mov ch, 0x00 ;; Track mov cl, 0x02 ;; Sector mov dh, 0x00 ;; Head mov bx, 0x2000 ;; Buffer end mov es, bx mov bx, 0x0000 ;; Buffer start int 0x13 jc loadkernel mov ax, 0x2000 mov ds, ax jmp 0x2000:0x00 If it makes any difference, I'm running a stock Dell Inspiron 15 BIOS. Apparently, the correct value for me is 0x80. The BIOS loads the hard drives and labels them starting at 0x80 according to this answer. My particular BIOS decides to load the USB drive up as the first, for some reason, so I can boot from there.
