• can't make svn store password, even though the configuration is set to allow it

  - by davka

  did everything the book says, i.e. removed the authentication files from .subversion/auth, and explicitly set the relevant config parameters to 'yes' even though this is a default, and yet the shell svn commands ask for password each time. The repository is on cvsdude.com, the client is linux. I also use the subclipse plugin that caches the password ok. I vaguely remember that when I started working with it, the command asked interactively if I wanted to save clear password, and I said no. Can this choice be stored somewhere and take precedence over the configuration? Thanks!

• MySQL Accept Any Password

  - by George

  Suppose that I have a test server with a large group of test accounts. The test accounts have unknown passwords which are hard-coded into the application's reports and are stored encrypted in the mysql.users table. Is there any option or hack which can be used to make mysql accept any text as the "correct" password for an account? For example: Update mysql.user Set Password="*" where 1=1 Note: The above line wouldn't work because it would literally set the password to "*" and not the wildcard character. However, I am looking for a way to create a mysql account which would accept anything as a valid password. This machine is disconnected from the network and I have full access to the mysql database...

• Problem with deployment of windows application using setup wizard.

  - by Mike

  I have some xml files, which are used in my application. They are stored in the same folder with application , in subfolder DATA: "C:\MyProject\DATA\". To get the DATA folder path i use this code : static public string GetDataFolderPath() { string s = System.IO.Directory.GetCurrentDirectory().Replace(@"\bin\Debug", ""); int i = s.LastIndexOf(@"\"); s = s.Substring(0, i); i = s.LastIndexOf(@"\"); s= s.Substring(0, i); return s + @"\Data\"; } So when i want to deploy my application, i create a setup project, and add the DATA folder to Application folder. But after i install the program f.e. "C:\Project"(DATA folder- "C:\Project\DATA" i got the error: "folder C:\DATA is not found". What i need to change to make things working after deployment. Why it looks for the DATA folder on 1 level higher?

• Force memcached to write to all servers in pool

  - by Industrial

  Hi everyone, I have thought a bit on how to make sure that a particular key is distributed to ALL memcached servers in a pool. My current, untested solution is to make another instance of memcached, something like this: $cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50); foreach ($this->cluster() as $cluster) { @$this->tempMemcache = new Memcache; @$this->tempMemcache->connect($cluster['host'], $cluster['port']); @$this->tempMemcache->set($key, $value, $this->compress, $expireTime); @$this->tempMemcache->close(); } What is common sense to do in this case, when certain keys need to be stored on ALL servers for reliability?

  Hi, I am using the pdist command to find the distance between x and y coordinates stored in a matrix. X = [100 100; 0 100; 100 0; 500 400; 300 600;]; D = pdist(X,'euclidean') Which returns a 15 element vector. : [0.734979755525412 3.40039811339820 2.93175207511321 1.83879677592575 2.40127440268306 2.75251513299386 2.21488402640753 1.10610649500317 1.81674017301699 0.903207751535635 1.99116952754924 1.05069952386082 1.24122819418333 1.08583377275532 1.38729428638035] Is there a way to associate these distances with the coordinates they were derived from, i.e. store them in a matrix with the general row form: [Length xcoordinate1 ycoordinate1 xcoordinate2 ycoordinate2] Where there is a row for each length found?

• INSERT 0..n records into table 'A' based on content of table 'B' in MySql 5

  - by Robert Gowland

  Using MySql 5, I have a task where I need to update one table based on the contents of another table. For example, I need to add 'A1' to table 'A' if table 'B' contains 'B1'. I need to add 'A2a' and 'A2b' to table 'A' if table 'B' contains 'B2', etc.. In our case, the value in table 'B' we're interested is an enum. Right now I have a stored procedure containing a series of statements like: INSERT INTO A SELECT 'A1' FROM B WHERE B.Value = 'B1'; --Repeat for 'B2' -> 'A2a'; 'B2' -> 'A2b'; 'B3' -> 'A3', etc... Is there a nicer more DRY way of accomplishing this? Edit: There may be values in table 'B' that have no equivalent value for table 'A'.

• How to avoid Mercurial repo corruption when sharing a repository between Windows/Mac?

  - by Stabledog

  I have several projects which are shared between Windows and Mac. The dev machine is a Mac running Parallels: the files are stored on the Mac side, and the source is shared to the Windows side. This is very convenient, as I can switch back and forth between Windows and Mac tools rapidly without having to sync files. Recently I switched from Subversion to Mercurial, and now I'm having problems with the Mercurial repository becoming corrupt if I use the Windows tools to add/update, etc. I have to be very careful about which operations on the Windows side are safe (mainly the read-only stuff) and of course I forget rather regularly. Does anybody know why the corruption occurs? I thought Mercurial repositories were platform-agnostic. Any ideas how to prevent it without removing the Windows tools entirely?

• What the best way to convert from String to HashMap?

  - by eugenn

  I would like to serialize a Java HashMap to string representation. The HashMap will contains only primitive values like string and integer. After that this string will be stored to db. How to restore back the HashMap? Is it make sense to use BeanUtils and interface Converter or use JSON? For example: List list = new ArrayList(); list.add(new Long(1)); list.add(new Long(2)); list.add(new Long(4)); Map map = new HashMap(); map.put("cityId", new Integer(1)); map.put("name", "test"); map.put("float", new Float(-3.2)); map.put("ids", list); map.toString() -> {float=-3.2,ids=[1, 2, 4],name=test,cityId=1} map.toJSON -> {"float":-3.2,"ids":[1,2,4],"name":"test","cityId":1}

• Django & custom auth backend (web service) + no database. How to save stuff in session?

  - by Infinity

  I've been searching here and there, and based on this answer I've put together what you see below. It works, but I need to put some stuff in the user's session, right there inside authenticate. How would I store acme_token in the user's session, so that it will get cleared if they logged out? class AcmeUserBackend(object): # Create a User object if not already in the database? create_unknown_user = False def get_user(self, username): return AcmeUser(id=username) def authenticate(self, username=None, password=None): """ Check the username/password and return an AcmeUser.

• Reading a simple Avro file from HDFS

  - by John Galt... who

  I am trying to do a simple read of an Avro file stored in HDFS. I found out how to read it when it is on the local file system.... FileReader reader = DataFileReader.openReader(new File(filename), new GenericDatumReader()); for (GenericRecord datum : fileReader) { String value = datum.get(1).toString(); System.out.println("value = " value); } reader.close(); My file is in HDFS, however. I cannot give the openReader a Path or an FSDataInputStream. How can I simply read an Avro file in HDFS? EDIT: I got this to work by creating a custom class (SeekableHadoopInput) that implements SeekableInput. I "stole" this from "Ganglion" on github. Still, seems like there would be a Hadoop/Avro integration path for this. Thanks

• What's the best way to test MSSQL connection programmatically?

  - by backslash17

  I need to develop a single routine that will be fired each 5 minutes to check if a list of MSSQL servers (10 to 12) are up and running. I can try to obtain a simple query in each one of the servers but this means that I have to create a table, view or stored procedure in every server, even if I use any already made SP I need to have a registered user in each server too. The servers are not in the same phisical location so having those requirements would be a complex task. Is there a way to simply "ping" from c# one MSSQL server? Thanks in advance!

• Working with version control on a Drupal/CMS project

  - by Jens Ljungblad

  I was wondering how teams that develop sites using Drupal (or any other CMS) integrate version control, subversion, git or similar, into their workflow. You'd obviously want your custom code and theme files under version control but when you use a CMS such as Drupal a lot of the work consists of configuring modules and settings all of which is stored in the database. So when you are a team of developers, how do you collaborate on a project like this? Dumping the database into a file and putting that file under version control might work I guess, but when the site is live the client is constantly adding content which makes syncing a bit problematic. I'd love to know how others are doing this.

• Why I should use an N-Tier Approach When using an SqlDatasource is ALOT EASIER ?

  - by The_AlienCoder

  When it comes to web development I have always tried to work SMART not HARD. So for along time My Aproach to interacting with databases in my AspNet projects has been this : 1) Create my stored procedures 2) Drag an SQLDatasource control on my aspx page 3) Bind a DataList Control to my SQLDatasource 4) Insert, Update & Delete by using my Datalist or programmatically using built in SQLDatasource methods e.g MySqlDataSource.InsertParameters["author"].DefaultValue = TextBox1.Text; MySqlDataSource.Insert(); Recently however I got a relatively easy web project. So I decided to employ a 3-tier Model...But I got exhausted halfway and just didnt seem worth it ! It seemed like I was working too HARD for a project that could have been easily accomplished by a couple of SqlDataSource Controls. So Why Is the N-Tier Model better than my Approach? Has it anything to do with performance? What are the advantages of the ObjectDataSource control over the SqlDataSource Control?

• Why does my CLR function keep disappearing

  - by user208080

  Hi there. I am a rookie to SQL and here is my questions. I have some CLR sql functions and procedures. When I deploy the 1st one, everything is fine. But after the 2nd one deployed, the first one will disappear. Anyone can help me out? Thanks a lot Actually, I simply create a new SQL project in VS, adding a new function or stored procedure, click deploy, and I can see the new function in my SQL instance. Then I close that project and open a new one, repeat the above steps, OK, the 2nd function is there i my instance but the 1st one disappeared or be replaced and no longer queryable for use. Thank you for your reply. All these clr functions and procedures are in the same instance of the database.

• Windows 2008 unable to execute c# powershell app. Returning access exception.

  - by scope-creep

  Hi, Does anybody know why I can't access the folder where my powershell scripts are in windows 2008 Ent. When I try to create a script with textpad it craps out. When I try and execute a c# powershell app, which is stored on another win 2003 drive, it craps out with an access exception as well. I've set powershell execution policy to unrestricted for both normal users and admin users with 'run as admin' on powershell, but it doesn't seem to make a difference. There must be a policy setting, doesn't allow scripts access to a directory, but where, and how to set it. Any help would be appreciated. scope_creep

• Connecting to TFS via ASP.NET, jQuery and Phonegap

  - by Tony D.

  I want to develop a mobile application that would allow the user the ability to run a suite of automated test cases housed in TFS. This is something I thought of this morning so it's all still very preliminary. But I'm curious as to what would be the best route for something like this? Or if it's even possible? Because the mobile devices from the users will vary from iphones to droids, I would probably want to incorporate something like Phonegap for it's cross platform capabilities. My initial thought was to develop in ASP.net/C# (which would be stored on a remote server), and have jQuery make calls to that server. Not sure if that would be the most appropriate way of handling this. I'm not too familiar with JSON but I have seen it as a suggestion on various sites to handle the returned data. Any thoughts or suggestions are appreciated. Thanks.

• How do I use Ajax and Jquery to get an array from PHP and post it?

  - by Jared

  Hello, I am using a separate PHP file as a configuration file for everything else on a basic ecommerce site. $product1["short"] = "product one"; $product1["menuimgslideshowsrc"] = "image/product1.jpg"; When I hover over a button, I want to get $product1["menuimgslideshowsrc"] and swap it out with an IMG SRC. I can do the swapping no problem, I need to know how to get the information stored in $product1["menuimgslideshowsrc"]. I assume I would use Ajax, but I am open to other ideas. Thanks in advance.

• Looking for an array (vs linked list) hashtable implementation in C

  - by kingusiu

  hi, I'm looking for a hashtable implementation in C that stores its objects in (twodimensional) arrays rather than linked lists. i.e. if a collision happens, the object that is causing the collision will be stored in the next free row index rather than pushed to the head and first element of a linked list. plus, the objects themselves must be copied to the hashtable, rather than referenced by pointers. (the objects do not live for the whole lifetime of the program but the table does). I know that such an implementation might have serious efficiency drawbacks and is not the "standard way of hashing" but as I work on a very special system-architecture i need those characteristics. thanks

• Is there a work around for setAppCacheEnabled on WebView for an Android 2.1 application causing the

  - by Kevin

  We have an HTML 5.0 web application that we ported to Android. It's our intention to run this in a Native Wrapper. Our application uses the ApplicationCache to run offline. This works find when running under the browser. While being hosted in a WebView within a native application, after the last file is downloaded and stored in the ApplicationCache from the manifest the application is terminated and does a core dump. This appears to be a documented bug. http://code.google.com/p/android/issues/detail?id=7939 Has anyone doing anything similar found a work around for this issue?

• Whats the best to way convert a set of Java objects to another set of objects?

  - by HDave

  Basic Java question here from a real newbie. I have a set of Java objects (of class "MyClass") that implement a certain interface (Interface "MyIfc"). I have a set of these objects stored in a private variable in my class that is declared as follows: protected Set<MyClass> stuff = new HashSet<MyClass>(); I need to provide a public method that returns this set as a collection of objects of type "MyIfc". public Collection<MyIfc> getMyStuff() {...} How do I do the conversion? The following line gives me an error that it can't do the conversion. I would have guessed the compiler knew that objects of class MyClass implemented MyIfc and therefore would have handled it. Collection<MyIfc> newstuff = stuff; Any enlightenment is appreciated.

• Storing dates i Train schedule MYSQL

  - by App_beginner

  Hi I have created a train schedule database in MYSQL. There are several thousand routes for each day. But with a few exceptions most of the routes are similar for every working day, but differ on weekends. At this time I basically update my SQL tables at midnight each day, to get the departures for the next 24 hours. This is however very inconvenient. So I need a way to store dates in my tables so I don't have to do this every day. I tried to create a separate table where I stored dates for each routenumber (routenumbers are resetted each day), but this made my query so slow that it was impossible to use. Does this mean I would have to store my departure and arrival times as datetimes? In that case the main table containing routes would have several million entries. Or is there another way? My routetable looks like this: StnCode (referenced in seperate Station table) DepTime ArrTime Routenumber legNumber
