  • Java: how to read BufferedReader faster

    - by Cata
    Hello, I want to optimize this code: InputStream is = rp.getEntity().getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(is)); String text = ""; String aux = ""; while ((aux = reader.readLine()) != null) { text += aux; } The thing is that i don't know how to read the content of the bufferedreader and copy it in a String faster than what I have above. I need to spend as little time as possible. Thank you

  • How do I create a safe local development environment?

    - by docgnome
    I'm currently doing web development with another developer on a centralized development server. In the past this has worked alright, as we have two separate projects we are working on and rarely conflict. Now, however, we are adding a third (possible) developer into the mix. This is clearly going to create problems with other developers changes affecting my work and vice versa. To solve this problem, I'm thinking the best solution would be to create a virtual machine to distribute between the developers for local use. The problem I have is when it comes to the database. Given that we all develop on laptops, simply keeping a local copy of the live data is plain stupid. I've considered sanitizing the data, but I can't really figure out how to replace the real data, with data that would be representative of what people actually enter with out repeating the same information over and over again, e.g. everyone's address becomes 123 Testing Lane, Test Town, WA, 99999 or something. Is this really something to be concerned about? Are there tools to help with this sort of thing? I'm using MySQL. Ideally, if I sanitized the db it should be done from a script that I can run regularly. If I do this I'd also need a way to reduce the size of the db itself. (I figure I could select all the records created after x and whack them and all the records in corresponding tables out so that isn't really a big deal.) The second solution I've thought of is to encrypt the hard drive of the vm, but I'm unsure of how practical this is in terms of speed and also in the event of a lost/stolen laptop. If I do this, should the vm hard drive file itself be encrypted or should it be encrypted in the vm? (I'm assuming the latter as it would be portable and doesn't require the devs to have any sort of encryption capability on their OS of choice.) The third is to create a copy of the database for each developer on our development server that they are then responsible to keep the schema in sync with the canonical db by means of migration scripts or what have you. This solution seems to be the simplest but doesn't really scale as more developers are added. How do you deal with this problem?

  • How to replace a region in emacs with yank buffer contents?

    - by Mad Wombat
    When I use VIM or most modeless editors (Eclipse, NetBeans etc.) I frequently do the following. If I have similar text blocks and I need to change them all, I will change one, copy it (or use non-deleting yank), select next block I need and paste the changed version over it. If I do the same thing in emacs (select region and paste with C-y), it doesn't replace the region, it just pastes at the cursor position. What is the way to do this in emacs?

  • C++: Accessing std::map keys and values

    - by Jay
    How do you access an std::vector of the keys or values of an std::map? Thanks. Edit: I would like to access the actual elements, not just copies of their contents. essentially I want a reference, not a copy. This is essentially what I am wanting to do: std::map<std::string, GLuint> textures_map; // fill map glGenTextures( textures_map.size(), &textures_map.access_values_somehow[0] );

  • Can multiple wordpress's feed off one database?

    - by ThomasReggi
    I am a template designer and I want to create one wordpress with all generic posts, but I don't want to have to keep logging in and copy & pasteing the same wordpress posts everytime. Can I point multiple WP installs to one database? A harder way would be export a master db and importing it to each install. Before I go crazy and try to hack something together, does anyone have any advise? -Thanks in advance.

  • PHP / Windows - Opendir() fails opening subdirectories within symbolic linked directories

    - by John Himmelman
    Does anyone know a solution to this problem? I'm unable to open a subdirectory within a symboliclink'd directory. I've confirmed that the paths are correct (even copy & pasted the path into explorer, which parsed it fine). This is a strange, annoying, bug :|. Example: C:\folder\symbolic_link\dir1\dir2 - opening dir2 fails. C:\folder\symbolic_link\dir1 - works C:\folder\real_directory\dir1\dir2 - works C:\folder\real_directory\dir1 - works

  • Subversion: Change working directory's target repo

    - by Aiden Bell
    I know, other RCS are better, but... I have moved an SVN repository from file:///path/to/repo to http://host.name/svn/repo but there is a working directory (checkout out from file://) with changes that want commiting to the http location. How then, can I change the repo a working directory will commit to when issuing svn commit? I'd rather do that than checkout a new copy and sync changes locally. Also, handy to know for the future.

  • C# Windows Service Multiple Config Files

    - by Goober
    Quick Question Is it possible to have more than 1 config file in a windows service? Or is there some way I can merge them at run time? Scenario Currently I have two config files containing the below contents. After I build and install my Windows Service, I can't get my custom XML Parser class to read the content because it keeps pointing to the wrong config file, even though I am using a few lines of code to ensure it gets the right name of the config file I need to access. ALSO When I navigate to the folder in which the service is installed, there is only sign of the normal APP.Config file, and no sign of the custom config file. (I have even set the normal ones properties to "Do Not Copy" and the custom ones properties to "Copy Always"). Config File Determination Code string settingsFile = String.Format("{0}.exe.config", System.AppDomain.CurrentDomain.BaseDirectory + Assembly.GetExecutingAssembly().GetName().Name); CUSTOM CONFIG File <?xml version="1.0" encoding="utf-8" ?> <configuration> <servers> <SV066930> <add name="Name" value = "SV066930" /> <processes> <SimonTest1> <add name="ProcessName" value="notepad.exe" /> <add name="CommandLine" value="C:\\WINDOWS\\system32\\notepad.exe C:\\WINDOWS\\Profiles\\TA2TOF1\\Desktop\\SimonTest1.txt" /> </SimonTest1> </processes> </SV066930> </servers> </configuration> NORMAL APP.CONFIG File <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxx" /> </configSections> <connectionStrings> <add name="DB" connectionString="Data Source=etc......" /> </connectionStrings> </configuration>

  • Why SVN makes read-only my files after check out or update?

    - by eKek0
    Working with an standard configuration of the server, without any lock, my files are read-only after every check out or update to the working copy. I have to set them to be not read-only to continue working, but besides this shouldn't be happening, it's uncomfortable. Anybody knows how to avoid this behavior?

  • MySQL Query For Copying Contents Into Another Field, Same Row

    - by Rob Adler
    Is there a single query (subqueries in it are allowed) where I can copy the content of one field into another field, per row. Example: price, and priceBackup Records: 45.55 47.77 45.55 copies into priceBackup for that specific row, 47.77 copies into priceBackup for that specific row. I do have a primary key, auto increment on it under 'id'. Thanks guys!

  • Are there any tools to speed up Cocoa development?

    - by user262325
    I noticed that there is much repeated work to do when creating Cocoa source code. For example, if I set an instance for an object: NSMutableArray *infoArray; I need add code: @property (retain,nonatomic) NSMutableArray *infoArray; @synthesize infoArray; in - (void)dealloc { I also need add: [infoArray release]; Is there any tool that can automate this, perhaps by automatically paste or copy the source code and add the repeated code at right place?

  • What does Apache need to support both mysqli and PDO?

    - by Nathan Long
    I'm considering changing some PHP code to use PDO for database access instead of mysqli (because the PDO syntax makes more sense to me and is database-agnostic). To do that, I'd need both methods to work while I'm making the changeover. My problem is this: so far, either one or the other method will crash Apache. Right now I'm using XAMPP in Windows XP, and PHP Version 5.2.8. Mysqli works fine, and so does this: $dbc = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password); echo 'Connected to database'; $sql = "SELECT * FROM `employee`"; But this line makes Apache crash: $dbc->query($sql); I don't want to redo my entire Apache or XAMPP installation, but I'd like for PDO to work. So I tried updating libmysql.dll from here, as oddvibes recommended here. That made my simple PDO query work, but then mysqli queries crashed Apache. (I also tried the suggestion after that one, to update php_pdo_mysql.dll and php_pdo.dll, to no effect.) Test Case I created this test script to compare PDO vs mysqli. With the old copy of libmysql.dll, it crashes if $use_pdo is true and doesn't if it's false. With the new copy of libmysql.dll, it's the opposite. if ($use_pdo){ $dbc = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password); echo 'Connected to database<br />'; $sql = "SELECT * FROM `employee`"; $dbc->query($sql); foreach ($dbc->query($sql) as $row){ echo $row['firstname'] . ' ' . $row['lastname'] . "<br>\n"; } } else { $dbc = @mysqli_connect($hostname, $username, $password, $dbname) OR die('Could not connect to MySQL: ' . mysqli_connect_error()); $sql = "SELECT * FROM `employee`"; $result = @mysqli_query($dbc, $sql) or die(mysqli_error($dbc)); while ($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) { echo $row['firstname'] . ' ' . $row['lastname'] . "<br>\n"; } } What does Apache need in order to support both methods of database query?
