  • Automatic language transformation in editor or IDE [on hold]

    - by Rumca
    Are there any tools that are capable of editing code but in different language? To be more concrete, I want to parse java source file in editor, compile it to my language X, edit in X and compile back to java on save. Or edit pom.xml file using non-XML syntax. Which editor or IDE would be easiest to use for implementing such prototype? Option to transform only a snippet would be ideal to limit effort on parsing. For one example, Intellij IDEA can display anonymous class so it looks like lambda expression hiding some of boilerplate.

  • NDepend v4 has just been released!

    - by Vincent Maverick Durano
    Few months ago I blogged about the release of NDepend v3 Continuous Integration and Reporting Capabilities here. Recently, the NDepend team has released v4 which comes with code rules based on C# LINQ queries (CQLinq), this make code ruling so much more powerful and flexible. There are couple of new rules available like: http://www.ndepend.com/DefaultRules/webframe?Q_UI_layer_shouldn't_use_directly_DB_types.html http://www.ndepend.com/DefaultRules/webframe?Q_Types_with_disposable_instance_fields_must_be_disposable.html http://www.ndepend.com/DefaultRules/webframe?Q_Avoid_the_Singleton_pattern.html http://www.ndepend.com/DefaultRules/webframe?Q_Avoid_making_complex_methods_even_more_complex_(Source_CC).html v4 also provides NDepend.API and a dozen of open-source code tool developed with NDepend.API (the Power Tools) http://www.ndepend.com/API/webframe.html

  • Is it relevant to warn about truncating real constants to 32 bits?

    - by zneak
    I'm toying around with LLVM and looking at what it would take to make yet another strongly-typed language, and now that I'm around the syntax, I've noticed that it seems to be a pet peeve of strongly typed language to warn people that their constants won't fit inside a float: // both in Java and C# float foo = 3.2; // error: implicitly truncating a double into a float // or something along these lines Why doesn't this work in Java and C#? I know it's easy to add the f after the 3.2, but is it really doing anything useful? Must I really be that aware that I'm using single-precision reals instead of double-precision reals? Maybe I'm just missing something (which, basically, is why I'm asking). Note that float foo = [const] is not the same thing as float foo = [double variable], where requiring the cast seems normal to me.

  • SQL join from multiple tables

    - by Kenny Anderson
    Hi all We've got a system (MS SQL 2008 R2-based) that has a number of "input" database and a one "output" database. I'd like to write a query that will read from the output DB, and JOIN it to data in one of the source DB. However, the source table may be one or more individual tables :( The name of the source DB is included in the output DB; ideally, I'd like to do something like the following (pseudo-SQL ahoy) SELECT output.UID, output.description, input.data from output.dbo.description LEFT JOIN (SELECT input.UID, input.data FROM [output.sourcedb].dbo.datatable ) AS input ON input.UID=output.UID Is there any way to do something like the above - "dynamically" specify the database and table to be joined on for each row in the query?

  • Insert record into mysql db with Entity Framework

    - by sanfra1983
    Hi, the problem is that it will insert a new record in a mysql table, I have already done the mapping of the mysql db and I have already done tests returning data and everything works. Now I read from a file, where there are queries written, I have them run me back and the result of true or false based on the final outcome of single query written to the file. Txt; I did this: using (var w = new demotestEntities ()) ( foreach (var l listaqueri) ( var p = we.CreateQuery <category> (l); we.SaveChanges (); result = true; ) ) but it does not work, I sense that it returns no errors, but neither the result given written in the query. txt file is as follows: INSERT INTO category (id, name) VALUES (null, 'test2') anyone can help me?

  • Convert Google results object (pure js) to Python object

    - by colwilson
    So I'm trying to use Google Map suggest API to request place name suggestions. Unfortunately I can't find the docs for this bit. Here is an example URI: http://maps.google.com/maps/suggest?q=lon&cp=3&ll=55.0,-3.5&spn=11.9,1.2&hl=en&gl=uk&v=2 which returns: {suggestion:[{query:"London",... I want to use this in python (2.5). Now in proper JSON there would have been quotations around the keys like so: {"suggestion":[{"query":"London",... and I could have used simplejson or something, but as it is I'm a bit stuck. There are two possible solutions here; either I can get to the API code and find an option to return proper JSON, or I do that in python. Any ideas please.

  • Creating a user called 'root'

    - by pnp
    I am creating Virtual Machines using the ubuntu-vm-builder. The syntax goes something like this: ubuntu-vm-builder kvm precise \ --domain newvm \ --dest newvm \ --arch i386 \ --hostname hostnameformyvm \ --mem 256 \ --user john \ --pass doe \ --ip 192.168.0.12 \ --mask 255.255.255.0 \ --net 192.168.0.0 \ --bcast 192.168.0.255 \ --gw 192.168.0.1 \ --dns 192.168.0.1 \ --mirror http://archive.localubuntumirror.net/ubuntu \ --components main,universe \ --addpkg acpid \ --addpkg vim \ --addpkg openssh-server \ --addpkg avahi-daemon \ --libvirt qemu:///system ; I need to enable the 'root' user account after creating each of my VMs (and supply a password for it). I was just wondering whether I can take this short-cut of supplying the username (--user) as root in this command itself. If I supply username as root to create my VMs, am I creating/enabling the root user, or just creating a user named as root? p.s.: any better ways to achieve my task are also welcome. But I don't want to manually meddle with each VM after its creation

  • How to learn more XMPP/Jabber command

    - by user359277
    Hi, I am using ejabberd as a chatting server now. And I am writing a client to chat and register new user. Right now, I know some of the protocol to register a new account, like sending the following command to register new user: <iq type="set"><query xmlns="jabber:iq:register"><username>wfwfewegwegwewefg</username><password>wfwefwefwefwef</password></query></iq> My question is: I want to learn more command/protocol to talk to the server. So where can I learn more? For example, How can I ask the server if the user name exists or not. How can I ask the server to unregister a user. What is the key word I should search for? Should I search for Jabber XMPP protocol or what? Thanks

  • $ON_USER returning root instead of $USER

    - by Nathanel Titane
    Hello everybody! With Natty coming out soon, I've been at work updating my deployment and self-config script to make my desktop on 11.04 run and look the way I want it to. One bummer is that dbus seems to have changed and does not permit, in the same manner Lucid and Maverick did, the authentication of the current user by terminal call using grep and cat. Ideally, to run the script, I would sudo -s and then launch it as # chmod +x install && ./install Instead of returning my user name.. it now returns root and applies changes to the root profile and aborts whenever paths do not correspond. Here is my script header: #!/bin/bash ON_USER=$(echo ~ | awk -F'/' '{ print $1 $2 $3 }' | sed 's/home//g') export $(grep -v "^#" ~/.dbus/session-bus/`cat /var/lib/dbus/machine-id`-0) if sudo -u $ON_USER test -z "$DBUS_SESSION_BUS_ADDRESS" ; then eval `sudo -u $ON_USER dbus-launch --sh-syntax --exit-with-session` fi RELEASE=$(lsb_release -cs) How could I make it return the actual user now that natty is coming? Thanks for the help

  • How to create initializeDB() method for java database

    - by Holly
    I am working on a Java project for class and have not worked much with incorporating databases into Java. I can't find much on the initializeDB() method, but if I could get some help I would really appreciate it. Below is the code being used for the intializeDB() method: private void initializeDB() { try { // Load the JDBC driver System.out.println("Driver loaded"); // Establish a connection System.out.println("Database connected"); // Create a statement // Create a SQL Query string // Execute the query to create a recordset } catch (Exception ex) { ex.printStackTrace(); } }

  • Post High Score and Retrieve Position

    - by majman
    I'm not so savvy with MYSQL, so my apologies in advance is this is a dumb question. I've created a super basic PHP High Scores table. Upon inserting a new score into the DB Table, I'd like to retrieve the position of that score so that I can get 10 results with the persons score falling within that range. My INSERT Query looks something like: $stmt = $mysqli->prepare("INSERT INTO highscores (name, time, score) VALUES (?, ?, ?)"); $stmt->bind_param('sdi', $name, $time, $score); UPDATE - I'm looking for a way to do this with as few queries as possible. I recall reading something about getting an INSERT ID when making an insert, but I would then still have to make a second query to get those results.

  • Scalable way of doing self join with many to many table

    - by johnathan
    I have a table structure like the following: user id name profile_stat id name profile_stat_value id name user_profile user_id profile_stat_id profile_stat_value_id My question is: How do I evaluate a query where I want to find all users with profile_stat_id and profile_stat_value_id for many stats? I've tried doing an inner self join, but that quickly gets crazy when searching for many stats. I've also tried doing a count on the actual user_profile table, and that's much better, but still slow. Is there some magic I'm missing? I have about 10 million rows in the user_profile table and want the query to take no longer than a few seconds. Is that possible?

  • Is there a way to give a subquery an alias in Oracle 11g SQL?

    - by Matt Pascoe
    Is there a way to give a subquery in Oracle 11g an alias like: select * from (select client_ref_id, request from some_table where message_type = 1) abc, (select client_ref_id, response from some_table where message_type = 2) defg where abc.client_ref_id = def.client_ref_id; Otherwise is there a way to join the two subqueries based on the client_ref_id. I realize there is a self join, but on the database I am running on a self join can take up to 5 min to complete (there is some extra logic in the actual query I am running but I have determined the self join is what is causing the issue). The individual subqueries only take a few seconds to complete by them selves. The self join query looks something like: select st.request, st1.request from some_table st, some_table st1 where st.client_ref_id = st1.client_ref_id;

  • mysql data being inserted twice via php

    I can't for the life of me figure out why this function is causing multiple entries into my database table...

  • Filter objects within two seconds of one another using SQLAlchemy

    - by Arrieta
    Hello: I have two tables with a column 'date'. One holds (name, date) and the other holds (date, p1, p2). Given a name, I want to use the date in table 1 to query p1 and p2 from table two; the match should happen if date in table one is within two seconds of date in table two. How can you accomplish this using SQLAlchemy? I've tried (unsuccessfully) to use the between operator and with a clause like: td = datetime.timedelta(seconds=2) q = session.query(table1, table2).filter(table1.name=='my_name').\ filter(between(table1.date, table2.date - td, table2.date + td)) Any thoughts?

  • How to use SQL - INSERT...ON DUPLICATE KEY UPDATE?

    - by Probocop
    Hi, I have a script which captures tweets and puts them into a database. I will be running the script on a cronjob and then displaying the tweets on my site from the database to prevent hitting the limit on the twitter API. So I don't want to have duplicate tweets in my database, I understand I can use 'INSERT...ON DUPLICATE KEY UPDATE' to achieve this, but I don't quite understand how to use it. My database structure is as follows. Table - Hash id (auto_increment) tweet user user_url And currently my SQL to insert is as follows: $tweet = $clean_content[0]; $user_url = $clean_uri[0]; $user = $clean_name[0]; $query='INSERT INTO hash (tweet, user, user_url) VALUES ("'.$tweet.'", "'.$user.'", "'.$user_url.'")'; mysql_query($query); How would I correctly use 'INSERT...ON DUPLICATE KEY UPDATE' to insert only if it doesn't exist, and update if it does? Thanks

  • SQL Native Client 10 Performance miserable (due to server-side cursors)

    - by namezero
    we have an application that uses ODBC via CDatabase/CRecordset in MFC (VS2010). We have two backends implemented. MSSQL and MySQL. Now, when we use MSSQL (with the Native Client 10.0), retrieving records with SELECT is dramatically slow via slow links (VPN, for example). The MySQL ODBC driver does not exhibit this nasty behavior. For example: CRecordset r(&m_db); r.Open(CRecordset::snapshot, L"SELECT a.something, b.sthelse FROM TableA AS a LEFT JOIN TableB AS b ON a.ID=b.Ref"); r.MoveFirst(); while(!r.IsEOF()) { // Retrieve CString strData; crs.GetFieldValue(L"a.something", strData); crs.MoveNext(); } Now, with the MySQL driver, everything runs as it should. The query is returned, and everything is lightning fast. However, with the MSSQL Native Client, things slow down, because on every MoveNext(), the driver communicates with the server. I think it is due to server-side cursors, but I didn't find a way to disable them. I have tried using: ::SQLSetConnectAttr(m_db.m_hdbc, SQL_ATTR_ODBC_CURSORS, SQL_CUR_USE_ODBC, SQL_IS_INTEGER); But this didn't help either. There are still long-running exec's to sp_cursorfetch() et al in SQL Profiler. I have also tried a small reference project with SQLAPI and bulk fetch, but that hangs in FetchNext() for a long time, too (even if there is only one record in the resultset). This however only happens on queries with LEFT JOINS, table-valued functions, etc. Note that the query doesn't take that long - executing the same SQL via SQL Studio over the same connection returns in a reasonable time. Question1: Is is possible to somehow get the native client to "cache" all results locally use local cursors in a similar fashion as the MySQL driver seems to do it? Maybe this is the wrong approach altogether, but I'm not sure how else to do this. All we want is to retrieve all data at once from a SELECT, then never talk the server again until the next query. We don't care about recordset updates, deletes, etc or any of that nonsense. We only want to retrieve data. We take that recordset, get all the data, and delete it. Question2: Is there a more efficient way to just retrieve data in MFC with ODBC?

  • Can I make PDOStatement->fetchObject not use non-member variables?

    - by threendib
    Lets say I have a class like this: Class User { var $id var $name; } And I run a query using PDO in php like so: $stm = $db->prepare('select * from users where id = :id'); $r = $stm->execute(array(':id' => $id)); $user = $r->fetchObject('User'); If I vardump my user object it has all kinds of other fields in it that I have not defined in the User class. Obviously I could make my query specific so that it only gives me back the fields I need/want. But if I don't want to do that is there any way to make this work the way I want it to? I like the idea of fetchObject, because it's one line of code to create this object and set member variables for me. I just don't want it to set variables I haven't defined in my class.

The script below changes the background position of the list item when the mouse is over the link. dojo.query('a[class=main-menu-link]').forEach(function(linkTwo) { dojo.connect(linkTwo, "onmouseover", function(evt) { dojo.query('#main-menu ul li').forEach(function(linkThree) { dojo.style(linkThree, { "backgroundPosition": "right center", }); }); You can see it in action in the right hand side menu: http://www.mechanic-one.suburban-glory.com/ I'm trying to work out the best of way of giving it a smooth transition between the two states... I've been looking on the Dojo documentation page but I'm not sure what is the best way of approaching it.
