  • Django internationalization for admin pages - translate model name and attributes

    - by geekQ
    Django's internationalization is very nice (gettext based, LocaleMiddleware), but what is the proper way to translate the model name and the attributes for admin pages? I did not find anything about this in the documentation: http://docs.djangoproject.com/en/dev/topics/i18n/internationalization/ http://www.djangobook.com/en/2.0/chapter19/ I would like to have "???????? ????? ??? ?????????" instead of "???????? order ??? ?????????". Note, the 'order' is not translated. First, I defined a model, activated USE_I18N = True in settings.py, run django-admin makemessages -l ru. No entries are created by default for model names and attributes. Grepping in the Django source code I found: $ ack "Select %s to change" contrib/admin/views/main.py 70: self.title = (self.is_popup and ugettext('Select %s') % force_unicode(self.opts.verbose_name) or ugettext('Select %s to change') % force_unicode(self.opts.verbose_name)) So the verbose_name meta property seems to play some role here. Tried to use it: class Order(models.Model): subject = models.CharField(max_length=150) description = models.TextField() class Meta: verbose_name = _('order') Now the updated po file contains msgid 'order' that can be translated. So I put the translation in. Unfortunately running the admin pages show the same mix of "???????? order ??? ?????????". I'm currently using Django 1.1.1. Could somebody point me to the relevant documentation? Because google can not. ;-) In the mean time I'll dig deeper into the django source code...

  • Streaming Media Player Tutorial Stops Unexpectedly. How Should I Debug (And Other Questions From A

    - by Danny
    Hello! I'm a fledgling in the Android and Eclipse ways. I was reading and downloaded the source code for a Streaming Media Player tutorial from Pocket Journey, here. However, when I try to run it through the "Run As..." or "Debug As..." features in Eclipse, the emulator reports: "Sorry! The application Android Tutorials (process com.pocketjourney.tutorials) has stopped unexpectedly. Please try again." Now, from stepping through the Tutorial 1 activity (for those of you that may be familiar with it), it seems something funky happens here: button.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Toast.makeText(Tutorial1.this, "Button Clicked",Toast.LENGTH_SHORT).show(); }}); My questions are: What's up with that line? Apparently, other comments haven't had this problem; am I missing some library that I should be downloading from someplace? How should I go about debugging this other than/in addition to stepping through code? I'm used to Visual Studio, which has a nice box with exception details for me to sift through and copy/paste to google with. Eclipse debugging showed a "No Source Code" page, or a list of exceptions. I've heard of something called LogCat; is that relevant here? Thanks in advance!

  • NAnt exec relative path

    - by stacker
    How can I assign to trunk.dir property a relative path to the trunk location? This is my nant.build file: <?xml version="1.0" encoding="utf-8"?> <project name="ProjectName" default="build" xmlns="http://nant.sf.net/release/0.85/nant.xsd"> <!-- Directories --> <property name="trunk.dir" value="C:\Projects\ProjectName" /><!-- I want relative path over here! --> <property name="source.dir" value="${trunk.dir}src\" /> <!-- Working Files --> <property name="msbuild.exe" value="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\msbuild.exe" /> <property name="solution.sln" value="${source.dir}ProjectName.sln" /> <!-- Called Externally --> <target name="compile"> <!-- Rebuild foces msbuild to clean and build --> <exec program="${msbuild.exe}" commandline="${solution.sln} /t:Rebuild /v:q" /> </target> </project>

  • Retrieving dll version info via Win32 - VerQueryValue(...) crashes under Win7 x64

    - by user256890
    The respected open source .NET wrapper implementation (SharpBITS) of Windows BITS services fails identifying the underlying BITS version under Win7 x64. Here is the source code that fails. NativeMethods are native Win32 calls wrapped by .NET methods and decorated via DllImport attribute. private static BitsVersion GetBitsVersion() { try { string fileName = Path.Combine( System.Environment.SystemDirectory, "qmgr.dll"); int handle = 0; int size = NativeMethods.GetFileVersionInfoSize(fileName, out handle); if (size == 0) return BitsVersion.Bits0_0; byte[] buffer = new byte[size]; if (!NativeMethods.GetFileVersionInfo(fileName, handle, size, buffer)) { return BitsVersion.Bits0_0; } IntPtr subBlock = IntPtr.Zero; uint len = 0; if (!NativeMethods.VerQueryValue(buffer, @"\VarFileInfo\Translation", out subBlock, out len)) { return BitsVersion.Bits0_0; } int block1 = Marshal.ReadInt16(subBlock); int block2 = Marshal.ReadInt16((IntPtr)((int)subBlock + 2 )); string spv = string.Format( @"\StringFileInfo\{0:X4}{1:X4}\ProductVersion", block1, block2); string versionInfo; if (!NativeMethods.VerQueryValue(buffer, spv, out versionInfo, out len)) { return BitsVersion.Bits0_0; } ... The implementation follows the MSDN instructions by the letter. Still during the second VerQueryValue(...) call, the application crashes and kills the debug session without hesitation. Just a little more debug info right before the crash: spv = "\StringFileInfo\040904B0\ProductVersion" buffer = byte[1900] - full with binary data block1 = 1033 block2 = 1200 I looked at the targeted "C:\Windows\System32\qmgr.dll" file (The implementation of BITS) via Windows. It says that the Product Version is 7.5.7600.16385. Instead of crashing, this value should return in the verionInfo string. Any advice?

  • 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...

  • How do I get Ctrl-Backspace to delete a word in vim within gnome-terminal?

    - by Michael Gundlach
    I'd like Ctrl-Backspace to delete the current word in vim insert mode. From within xterm I can pull this off via :inoremap <C-H> <C-W> but in gnome-terminal I cannot figure out a way to make it happen. When in vim insert mode, if I type control-v and then press backspace, I get ^H in xterm, and ^? in gnome-terminal. Unfortunately, :inoremap <C-?> <C-W> doesn't do the trick in gnome-terminal; control-backspace just erases a single character no matter what. Regarding ASCII codes: Gnome-terminal lets you change the backspace character under Edit - Profile Preferences - Compatibility. Unfortunately, no option works, as far as I can tell: whatever character I apply to Backspace via the settings, if I try mapping the character itself, like :inoremap <C-H> <C-W> then regular backspace and control-backspace both erase an entire word; and if I try mapping control plus that character, like :inoremap <C-^H> <C-W> then regular backspace and control-backspace just erase a single character.

  • Problem with DSL and Business Rules creation in Drools

    - by jillika iyer
    Hi, I am using Eclipse with the Drools plugin to create rules. I want to create business rules and main aim is to try and provide the user a set of options which he can use to create rules. For eg:If an Apple can have only 3 colors: I want to provide an option like a drop down so that the user can know before hand which are the options he can use in his rules. Is it possible? I am creating a dsl but unable to still provide the above functionality for a business rule. I am having an error implementing a basic dsl also. The code to add the dsl is as follows in my RuleRunner class() InputStream ruleSource = RuleRunner.class.getClassLoader().getResourceAsStream("/Rule1.dslr"); InputStream dslSource = RuleRunner.class.getClassLoader().getResourceAsStream("/sample-dsl.dsl"); //Load the rules , using DSL addRulesToThisPackage.addPackageFromDrl( new InputStreamReader(ruleSource),new InputStreamReader(dslSource)); I have both the sample-dsl .dsl and Rule1.dslr in my working directory. Error encountered at adding the dsl to the package (last line) Error stack: Exception in thread "main" java.lang.NullPointerException at java.io.Reader.<init>(Unknown Source) at java.io.InputStreamReader.<init>(Unknown Source) at com.org.RuleRunner.loadRuleFile(RuleRunner.java:96) at com.org.RuleRunner.loadRules(RuleRunner.java:48) at com.org.RuleRunner.runStatelessRules(RuleRunner.java:109) at com.org.RulesTest.main(RulesTest.java:41) my dsl file has basic mapping as per the online documentations. The dsl rule I created is: expander sample-dsl.dsl rule "A status changes B status" when There is an A - has an address There is a B - has name then - print updated A and Aaddress End I have created DSL in eclipse. Is the code I added for it to be loaded to my package correct?? Or am I missing something???? It seems like my program is unable to find the dsl? Please help. Can you point me towards the right direction to create a user friendly business rule ?? Thanks. J

  • Copy SQL Server data from one server to another on a schedule

    - by rwmnau
    I have a pair of SQL Servers at different webhosts, and I'm looking for a way to periodically update the one server using the other. Here's what I'm looking for: As automated as possible - ideally, without any involvement on my part once it's set up. Pushes a number of databases, in their entirely (including any schema changes) from one server to the other Freely allows changes on the source server without breaking my process. For this reason, I don't want to use replication, as I'd have to break it every time there's an update on the source, and then recreate the publication and subscription One database is about 4GB in size and contains binary data. I'm not sure if there's a way to export this to a script, but it would be a mammoth file if I did. Originally, I was thinking of writing something that takes a scheduled full backup of each database, FTPs the backups from one server to the other once they're done, and then the new server picks it up and restores it. The only downside I can see to this is that there's no way to know that the backups are done before starting to transfer them - can these backups be done synchronously? Also, the server being refreshes is our test server, so if there's some downtime involved in moving the data, that's fine. Does anybody out there have a better idea, or is what I'm currently considering the best non-replication way to go? Thanks for your help, everybody. UPDATE: I ended up designing a custom solution to get this done using BAT files, 7Zip,command line FTP, and OSQL, so it runs in a completely automatic way and aggregates the data from a dozen servers across the country. I've detailed the steps in a blog entry. Thanks for all your input!

  • jdbc query - date ranges as parameters

    - by pstanton
    Hi all, I'd like to write a single JDBC statement that can handle the equivalent of any number of NOT BETWEEN date1 AND date2 where clauses. By single query, i mean that the same SQL string will be used to create the JDBC statements and then have different parameters supplied. This is so that the underlying frameworks can efficiently cache the query (i've been stung by that before). Essentially, I'd like to find a query that is the equivalent of SELECT * FROM table WHERE mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? and at the same time could be used with fewer parameters: SELECT * FROM table WHERE mydate NOT BETWEEN ? AND ? or more parameters SELECT * FROM table WHERE mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? AND mydate NOT BETWEEN ? AND ? I will consider using a temporary table if that will be simpler and more efficient. thanks for the help!

  • Help getting MVVM ViewModel to bind to the View

    - by cw
    Okay guys, I'm new to this model and Silverlight in general. I have the following code (changed object names, so syntax/spelling errors ignore). public class ViewModel { ViewModelSource m_vSource; public ViewModel(IViewModelSource source) { m_vSource= source; m_vSource.ItemArrived += new Action<Item>(m_vSource_ItemArrived); } void m_vSource_ItemArrived(Item obj) { Title = obj.Title; Subitems = obj.items; Description = obj.Description; } public void GetFeed(string serviceUrl) { m_vFeedSource.GetFeed(serviceUrl); } public string Title { get; set; } public IEnumerable<Subitems> Subitems { get; set; } public string Description { get; set; } } Here is the code I have in my page's codebehind. ViewModel m_vViewModel; public MainPage() { InitializeComponent(); m_vViewModel = new ViewModel(new ViewModelSource()); this.Loaded += new RoutedEventHandler(MainPage_Loaded); this.DataContext = m_vViewModel; } void MainPage_Loaded(object sender, RoutedEventArgs e) { m_vViewModel.GetItems("http://www.myserviceurl.com"); } Finally, here is a sample of what my xaml looks like. <!--TitleGrid is the name of the application and page title--> <Grid x:Name="TitleGrid" Grid.Row="0"> <TextBlock Text="My Super Title" x:Name="textBlockPageTitle" Style="{StaticResource PhoneTextPageTitle1Style}"/> <TextBlock Text="{Binding Path=Title}" x:Name="textBlockListTitle" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid> I know I'm missing something, but I'm just not knowledgable enough which is why I'm asking you guys :) Is there anything I'm doing wrong here?

  • How can I place zeroes to the left of a given number to a maximum of 6 digits including the given nu

    - by Sergio Tapia
    I have this method that receives an ID number and downloads an HTML website according to that ID. Typically, an IMDB link is like this: http://www.imdb.com/title/tt0892791/ http://www.imdb.com/title/tt1226229/ http://www.imdb.com/title/tt0000429/ They all follow the 'tt' then 7 digits, with lack of digits turning into zeroes to fill out the left spaces. How can I accomplish this using C#? I'm kind of stumped. Here's my method: /// <summary> /// Find a movie page using its precise IMDB id. /// </summary> /// <param name="id">IMDB Movie ID</param> /// <returns>Returns an HtmlDocument with the source code included.</returns> public HtmlDocument ByID(string id) { string url = String.Format("http://www.imdb.com/title/tt{0}/", id); HtmlDocument page = downloader.Load(url); return page; } Thank you very much for your time, and if you are interested in helping out, you can check out the complete source code of TheFreeIMDB here: http://thefreeimdb.codeplex.com/

  • Help Modifying Generic REST Helper PHP Example Code to Support XML DOM

    - by Jennifer Baker
    Hi! I found this example PHP source code at HTTP POST from PHP, without cURL I need some help modifying the example PHP source to support XML DOM for manipulating a REST API. I thought that if I update the CASE statement for the XML section below from $r = simplexml_load_string($res); to $r = new DOMDocument(); $r->load($res); that it would work but it doesn't. :( Any help would be appreciated. function rest_helper($url, $params = null, $verb = 'GET', $format = 'xml') { $cparams = array( 'http' => array( 'method' => $verb, 'ignore_errors' => true ) ); if ($params !== null) { $params = http_build_query($params); if ($verb == 'POST') { $cparams['http']['content'] = $params; } else { $url .= '?' . $params; } } $context = stream_context_create($cparams); $fp = fopen($url, 'rb', false, $context); if (!$fp) { $res = false; } else { // If you're trying to troubleshoot problems, try uncommenting the // next two lines; it will show you the HTTP response headers across // all the redirects: // $meta = stream_get_meta_data($fp); // var_dump($meta['wrapper_data']); $res = stream_get_contents($fp); } if ($res === false) { throw new Exception("$verb $url failed: $php_errormsg"); } switch ($format) { case 'json': $r = json_decode($res); if ($r === null) { throw new Exception("failed to decode $res as json"); } return $r; case 'xml': $r = simplexml_load_string($res); if ($r === null) { throw new Exception("failed to decode $res as xml"); } return $r; } return $res; }

  • Find out which row caused the error

    - by Felipe Fiali
    I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query there was an error converting some varchar to datetime. It turned out to be that they had some sales dating '2009-02-29', an out-of-range date. And yes, I know. Why was that stored as varchar? Well, the source database has 3 columns for dates, 'Month', 'Day' and 'Year'. I have no idea why it's like that, but still, it is. But how the hell would I treat that, if the source is not trustable? I can't HANDLE exceptions, I really need that it comes up to another level with the original message, but I wanted to provide some more info, so that the user could at least try to solve it before calling us. So I thought about displaying to the user the row number, or some ID that would at least give him some idea of what record he'd have to correct. That's also a hard job because there will be times when the integration will run up to 80000 records. And in an 80000 records integration, a single dummy error message: 'The conversion of a varchar data type to a datetime data type resulted in an out-of-range datetime value' means nothing at all. So any idea would be appreciated. Oh I'm using SQL Server 2005 with Service Pack 3.

  • Raw types and subtyping

    - by Dmitrii
    We have generic class SomeClass<T>{ } We can write the line: SomeClass s= new SomeClass<String>(); It's ok, because raw type is supertype for generic type. But SomeClass<String> s= new SomeClass(); is correct to. Why is it correct? I thought that type erasure was before type checking, but it's wrong. From Hacker's Guide to Javac When the Java compiler is invoked with default compile policy it performs the following passes: parse: Reads a set of *.java source files and maps the resulting token sequence into AST-Nodes. enter: Enters symbols for the definitions into the symbol table. process annotations: If Requested, processes annotations found in the specified compilation units. attribute: Attributes the Syntax trees. This step includes name resolution, type checking and constant folding. flow: Performs data ow analysis on the trees from the previous step. This includes checks for assignments and reachability. desugar: Rewrites the AST and translates away some syntactic sugar. generate: Generates Source Files or Class Files. Generic is syntax sugar, hence type erasure invoked at 6 pass, after type checking, which invoked at 4 pass. I'm confused.

  • SQLiteDataAdapter Update method returning 0

    - by Lirik
    I loaded 83 rows from my CSV file, but when I try to update the SQLite database I get 0 rows... I can't figure out what I'm doing wrong. The program outputs: Num rows loaded is 83 Num rows updated is 0 The source code is: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); Console.WriteLine("Num rows loaded is " + ds.Tags.Rows.Count); InsertData(ds, tableName); } } } public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { using (new SQLiteCommandBuilder(sqliteAdapter)) { conn.Open(); Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } } Any hints on why it's not updating the correct number of rows?

  • 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.

  • Pros/cons of reading connection string from physical file vs Application object (ASP.NET)?

    - by HaterTot
    my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production). It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings. I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often). I was considering storing the connection string in Application["ConnectionString"]. So the code would be public static string GetConnectionString { if (Application["ConnectionString"] == null) { XmlDocument doc = new XmlDocument(); doc.Load(HttpContext.Current.Request.PhysicalApplicationPath + "bin/ServerEnvironment.xml"); XmlElement xe = (XmlElement) xnl[0]; switch (xe.InnerText.ToString().ToLower()) { case "local": connString = Settings.Default.ConnectionStringLocal; break; case "development": connString = Settings.Default.ConnectionStringDevelopment; break; case "production": connString = Settings.Default.ConnectionStringProduction; break; default: throw new Exception("no connection string defined"); } Application["ConnectionString"] = connString; } return Application["ConnectionString"].ToString(); } I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons? Do you think I'd see a small performance gain by implementing the function above? THANKS

  • Nothing gets displayed when debugging Microsoft Surface

    I am trying to write my first Microsoft Surface application, and am doing the development on the Surface unit itself. I successfully re-created the quick "Photos" application that is shown on the PDC Video, however, now that I'm trying to create my own app - nothing actually shows up when I run it. I'm mainly just adding ScatterViews right now - and they show up fine in the designer, but as soon as I hit F5 - the shell is shown on the surface - but none of the ScatterViews show up.

OleDbCommand dbCommand = new OleDbCommand(strSQL, excelConnection); OleDbDataAdapter dataAdapter = new OleDbDataAdapter(dbCommand); // create data table DataTable dTable = new DataTable(); dataAdapter.Fill(dTable); // bind the datasource // dataBingingSrc.DataSource = dTable; // assign the dataBindingSrc to the DataGridView // dgvExcelList.DataSource = dataBingingSrc; // dispose used objects if (dTable.Rows.Count > 0) MessageBox.Show("Count:" + dTable.Rows.Count.ToString()); dTable.Dispose(); dataAdapter.Dispose(); dbCommand.Dispose(); excelConnection.Close(); excelConnection.Dispose(); }

  • Are Fortran control characters (carriage control) still implemented in compilers?

    - by CmdrGuard
    In the book Fortran 95/2003 for Scientists and Engineers, there is much talk given to the importance of recognizing that the first column in a format statement is reserved for control characters. I've also seen control characters referred to as carriage control on the internet. To avoid confusion, by control characters, I refer to the characters "1, a blank (i.e. \s), 0, and +" as having an effect on the vertical spacing of output when placed in the first column (character) of a FORMAT statement. Also, see this text-only web page written entirely in fixed-width typeface : Fortran carriage-control (because nothing screams accuracy and antiquity better than prose in monospaced font). I found this page and others like it to be not quite clear. According to Fortran 95/2003 for Scientists and Engineers, failure to recall that the first column is reserved for carriage control can lead to horrible unintended output. Paraphrasing Dave Barry, type the wrong character, and nuclear missiles get fired at Norway. However, when I attempt to adhere to this stern warning, I find that gfortran has no idea what I'm talking about. Allow me to illustrate my point with some example code. I am trying to print out the number Pi: PROGRAM test_format IMPLICIT NONE REAL :: PI = 2 * ACOS(0.0) WRITE (*, 100) PI WRITE (*, 200) PI WRITE (*, 300) PI 100 FORMAT ('1', "New page: ", F11.9) 200 FORMAT (' ', "Single Space: ", F11.9) 300 FORMAT ('0', "Double Space: ", F11.9) END PROGRAM test_format This is the output: 1New page: 3.141592741 Single Space: 3.141592741 0Double Space: 3.141592741 The "1" and "0" are not typos. It appears that gfortran is completely ignoring the control character column. My question, then, is this: Are control characters still implemented in standards compliant compilers or is gfortran simply not standards compliant? For clarity, here is the output of my gfortran -v Using built-in specs.

  • Capistrano fails for multiple host deployments

    - by morris082
    I be at a loss here, and after scouring the seas (read: internet) for solutions I am left with none other than to hit up the stack. any help appreciated. I have capistrano running locally for deployments onto several different environments. (I'm on windows 7, fwiw). All was well until I needed to deploy to multiple :app servers during a single deployment. Usually I'm prompted for my ssh passphrase once when I call 'cap deploy'. I have ssh-agent running (git never pesters for my pass) but despite this Capistrano has always bugged me once each deployment. Regardless, it always worked when deploying to ONE host. Now, when I attempt to deploy to multiple servers at once, it asks for my passphrase what appears to be multiple times: (ips removed by ME) servers: ["redacted", "redacted"]<br /> Enter passphrase for ~/.ssh/id_rsa: Enter passphrase for ~/.ssh/id_rsa: So with the above I enter my passphrase but this doesn't work. It waits as little while, then spits out this error: connection failed for: <one of the server ips> (NoMethodError: undefined method `overwrite' for nil:NilClass) And that's the end of that. I can "passwordless" ssh into the servers I'm deploying on just fine. I'm pretty certain the ssh-agent is running since I can hit Git w/out entering my passphrase every time Using 'forward_agent' setting in cap deploy did not work. This is my role: role :app, "ip 1 removed", "ip 2 removed" If i set default_run_options[:max_hosts] = 1, it works OK but it asks for my passphrase for every single connection to each host I'm deploying to.. which ends up being a lot. Essentially I'm looking for any of the below (but not limited to): - "You're never going to fix that on windows" - "This is how you get REAL passwordless deployment in capistrano" - "Have you overlooked this setting/feature?" - "I have a rock that can fix anything, you may borrow it" Thanks!

  • How to get the actual address of a pointer in C?

    - by Airjoe
    BACKGROUND: I'm writing a single level cache simulator in C for a homework assignment, and I've been given code that I must work from. In our discussions of the cache, we were told that the way a small cache can hold large addresses is by splitting the large address into the position in the cache and an identifying tag. That is, if you had an 8 slot cache but wanted to store something with address larger than 8, you take the 3 (because 2^3=8) rightmost bits and put the data in that position; so if you had address 22 for example, binary 10110, you would take those 3 rightmost bits 110, which is decimal 5, and put it in slot 5 of the cache. You would also store in this position the tag, which is the remaining bits 10. One function, cache_load, takes a single argument, and integer pointer. So effectively, I'm being given this int* addr which is an actual address and points to some value. In order to store this value in the cache, I need to split the addr. However, the compiler doesn't like when I try to work with the pointer directly. So, for example, I try to get the position by doing: npos=addr%num_slots The compiler gets angry and gives me errors. I tried casting to an int, but this actually got me the value that the pointer was pointing to, not the numerical address itself. Any help is appreciated, thanks!

  • What is difference between my atoi() calls?

    - by Lucas
    I have a big number stored in a string and try to extract a single digit. But what are the differences between those calls? #include <iostream> #include <string> int main(){ std::string bigNumber = "93485720394857230"; char tmp = bigNumber.at(5); int digit = atoi(&tmp); int digit2 = atoi(&bigNumber.at(5)) int digit3 = atoi(&bigNumber.at(12)); std::cout << "digit: " << digit << std::endl; std::cout << "digit2: " << digit2 << std::endl; std::cout << "digit3: " << digit3 << std::endl; } This will produce the following output. digit: 7 digit2: 2147483647 digit3: 57230 The first one is the desired result. The second one seems to me to be a random number, which I cannot find in the string. The third one is the end of the string, but not just a single digit as I expected, but up from the 12th index to the end of the string. Can somebody explain the different outputs to me? EDIT: Would this be an acceptable solution? char tmp[2] = {bigNumber.at(5), '\0'}; int digit = atoi(tmp); std::cout << "digit: " << digit << std::endl;

  • connecting to MySQL using JDBC in eclipse

    - by Noona
    Hello, So I want to create a JDBC connection to MySQL server that is installed on my pc, here are the steps, I installed MySQL with the username and password "root", downloaded mysql-connector-java and from theere I coped the JAR "mysql-connector-java-5.1.12-bin" to "C:\Sun\SDK\jdk\jre\lib\ext", I then added it as an external JAR in my project in eclipse, now in my class I have this code: public void initialiseDatabase() { try { // Load the Driver class. Class.forName("com.mysql.jdbc.Driver"); //Create the connection using the static getConnection method databaseConnection = DriverManager.getConnection (databaseUrl+databaseName, dbUserName, dbPassword); sqlStatement = databaseConnection.createStatement(); } catch (SQLException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();} } (this is going to be psuedocode cause I am reading from a properties file and don't want the one helping me reading through long lines of code from main to figure out all the variables), where databaseUrl = "127.0.0.1" dbUserName = "root" dbPassword = "root" databaseName = "MySQL" //this one I am not sure of, do I need to create it or is it set inherenrly? now the MySQL server is up and running, but when I call the method initialiseDatabase the following exception is thrown: "java.sql.SQLException: No suitable driver found for rootroot at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at Proxy$JDBCConnection.initialiseDatabase(Proxy.java:721)" when line 721 is: sqlStatement = databaseConnection.createStatement(); Where have I gone wrong? thanks
