• 32-bit ODBC on Windows Server 2008 R2

  - by John Paul Cook

  Heterogeneous data access requires having the right drivers. If you have to use 32-bit ODBC drivers, you won’t find then when you start the Microsoft ODBC Administrator because it is 64-bit. The 32-bit ODBC Administrator is found here: C:\Windows\SysWOW64\odbcad32.exe You might want to make a shortcut for it to make it easy to find. You’ll need to use it when make 32-bit ODBC data connections. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!...(read more)

• Random map generation

  - by Thomas Owers

  I'm starting/started a 2D tilemap RPG game in Java and I want to implement random map generation. I have a list of different tiles, (dirt/sand/stone/grass/gravel etc) along with water tiles and path tiles, the problem I have is that I have no idea where to start on generating a map randomly. It would need to have terrain sections (Like a part of it will be sand, part dirt, etc.) Similar to how Minecraft is where you have different biomes and they seamlessly transform into each other. Lastly I would also need to add random paths into this as well going in different directions all over the map. I'm not asking anyone to write me all the code or anything, just piont me into the right direction please. tl;dr - Generate a tile map with biomes, paths and make sure the biomes seamlessly go into each other.

• Best Practice - XML To Excel

  - by MemLeak

  I've to read a big XML file with a lot of information. Afterwards I extract the needed information (~20 Points(columns) / ~80 relevant Data (rows, some of them with subdatasets) and write them out in a Excel File. My Question is how to handle the extraction (of unused Data) part, should I copy the whole file and delete the unused parts, and then write it to excel or is it a good approach to create Objects for each column? should I write the whole xml to excel and start to delete rows in excel? What would be performant and a acceptable solution?

• Pros and cons of using Grails compared to pure Groovy

  - by shabunc

  Say, you (by you I mean an abstract guy, any guy in your team) have experience of writing and building java web apps, know about filters, servlet mappings and so on, and so on. Also, let us assume you know pretty well any sql db, no matter which one exactly, whether it mysql, oracle or psql. At last, let pretend we know Groovy and its standard libraries, for example all that JsonBuilder and XmlSlurper stuff, so we don't need grails converters. The question is - what are benefits of using grails in this case. I'm not trying to start flame war, I'm just asking to compare - what are ups and downs of grails development compared to pure groovy one. For instance, off the top of my head I can name two pluses - automatic DB mapping and custom gsp tags. But when I want to write a modest app which provides small API for handling some well defined set of data, I'm totally OK with groovy's awesome SQL support. As for gsp, we does not use it at all, so we are not interested in custom tags as well.

• With respect to gnome-session, what is a "component"?

  - by Alistair Buxton

  Under /usr/share/gnome-session/sessions are files which describe the different types of sessions available from gnome-session. In these files is a list of required components, eg for shell: RequiredComponents=gnome-shell;gnome-settings-daemon; or for fallback: RequiredComponents=gnome-panel;gnome-settings-daemon; This appears to be a list of executables, but it is not. If I change gnome-panel to some other type of panel, the session does not start, and I see the following errors in ~/.xsession-errors: gnome-session[2003]: WARNING: Unable to find required component 'xfce4-panel' So my question: What is a component, how are they defined, and where does gnome-session look for them?

• How to change the default editor of a specific file type in JDeveloper

  - by [email protected]

  When you open a file in JDeveloper, the mode that is used as the default might not be what you as a developer want.  If, for example, every time you open a .jsp(x) file you click on the source tab at the bottom of the window so that you can edit the jsp(x) file in source code mode, you may want to consider changing the default editor for that file type.  This is easy to do in the JDeveloper tool preferences and can be a time saver in the long run, since some editors can take a while to start up and if you don't need them often, this would just be lost time.  Here are the steps:  From the JDeveloper menu, select Tools->Preferences...Select "File Types" in the tree component on the left side of the preferences dialog.Click on the "Default Editors" tab.Scroll to the file type you want to change.In the details section at the bottom of the dialog, use the "Default Editor" select list to change the default to your liking.

• What datastructure would you use for a collision-detection in a tilemap?

  - by Solom

  Currently I save those blocks in my map that could be colliding with the player in a HashMap (Vector2, Block). So the Vector2 represents the coordinates of the blog. Whenever the player moves I then iterate over all these Blocks (that are in a specific range around the player) and check if a collision happened. This was my first rough idea on how to implement the collision-detection. Currently if the player moves I put more and more blocks in the HashMap until a specific "upper bound", then I clear it and start over. I was fully aware that it was not the brightest solution for the problem, but as said, it was a rough first implementation (I'm still learning a lot about game-design and the data-structure). What data-structure would you use to save the Blocks? I thought about a Queue or even a Stack, but I'm not sure, hence I ask.

• Qt question: hard-coded shortcuts

  - by miLo

  I have asked this question on several places but I still can't figure it out. What I am trying to do is to have a QKeySequence(Qt::CTRL + Qt::Key_X, Qt::CTRL + Qt::Key_C) in a MainWindow with QTextEdit as a central widget. The problem is that I have a shorcut for Cut(Ctrl+X) and when I press Ctrl+X,Ctrl+C it doesn't work. When the focus is on diffrent widget the shorcut works perfectly. I tried with overriding the QWidget::keyPressEvent and QWidget::event but it is the same. I have one more question: if I have these two shorcuts Ctrl+X and Ctrl+XCtrl+C why I don't receive the signal activatedAmbigiously() when I press Ctrl+X? According to the Qt documentation When a key sequence is being typed at the keyboard, it is said to be ambiguous as long as it matches the start of more than one shortcut.

• How do I document my code?

  - by Brian Ortiz

  I'm a hobbyist programmer (with no formal education) looking to start doing small freelance jobs. One of the things that hobbyist programmers can get away with that those with a "real" job can't is lack of documentation. After all, you wrote it so you know how it works. I feel a little silly asking because it seems like such a basic thing, but how do I document my code? How should it be formatted? How should it be presented? (HTML pages? LaTeX?) What does/doesn't need to be documented? ...And maybe more specifics I haven't thought of. I mostly program in PHP but also C#.

• Project planning and customer tracking system

  - by Daniel Hollands

  First off, sorry if this is the wrong 'stack' site, but it seemed like a good place to start. I'm happy to report that my services as a web developer are starting to be in quite a lot of demand, and I have a few existing and potentially new customers all lining up - but I'm finding it very hard to keep track of everything. What I'm hoping for is some (preferably web-based) system which I can use to keep track of who my customers are, the various projects that I've got going on for them, and (if possible) the individual sub-tasks that make up each project. What would be even better is if the relevant customer was able to log into the site, and see the process of their projects. I do hope you know what I'm talking about, and that you'll be able to offer some suggestions of either web-base sites that offer something along these lines, or of some open source solution or something like that? Thank you

• How to list missing partitions?

  I have installed Ubuntu on one of my partition and Crunchbang on the other partition. As I wanted to make some continuous space, I moved Crunchbang partition and then checked fdisk output which looks like this Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc7996dfa Device Boot Start End Blocks Id System /dev/sda1 * 63 80324 40131 de Dell Utility /dev/sda4 81918 625139711 312528897 f W95 Ext'd (LBA) /dev/sda5 81920 211816447 105867264 83 Linux /dev/sda6 299100160 341043199 20971520 83 Linux /dev/sda7 341045248 625139711 142047232 7 HPFS/NTFS/exFAT I cannot see sda2 and sda3 partition.

• Setup Convergence Address Book DisplayName Lookup

  - by user13332755

  At Convergence Address Book the default lookup for 'Display Name' is the LDAP attribute 'cn', which leads into confusion if you start to setup 'displayName' LDAP attributes for your users. LDAP User Entry with diaplyName attribute: This behavior can be controlled by the configuration file xlate-inetorgperson.xml. Change the default value of XPATH abperson\entry\displayname from 'cn' to 'displayName'. <convergence_deploy_location>/config/templates/ab/corp-dir/xlate-inetorgperson.xml Note: In case the user has no 'displayName' attribute in LDAP you might noticed '...' at the user entry, if found via 'mail' attribute.

• How to make Jetty webserver listen on port 80?

  - by Jonas

  I would like to use Jetty as a webserver. I have edited the configuration file at /etc/default/jetty and set: # change to 0 to allow Jetty start NO_START=0 # Listen to connections from this network host # Use 0.0.0.0 as host to accept all connections. JETTY_HOST=0.0.0.0 Now I can reach the Jetty webserver at http://192.168.1.10:8080 but I would like to have Jetty listening on port 80. I have tried this setting in the same configuration file: # The network port used by Jetty JETTY_PORT=80 and then restart Jetty with sudo service jetty restart but it doesn't work. How can I change so that the Jetty webserver is listening on port 80?

• Unable to mount external hard drive

  Basically I my 12.10 update crashed halfway through, so I've had to start again and put all my data onto an external HDD.

• Kansas City Developer's Conference

  - by Brian Schroer

  I just found about about / registered for Saturday’s Kansas City Developer’s Conference, and am going to make the drive over from the right side of the state (Hey, no offense, KC – I’m just looking at a map, and St. Louis is on the right side, Kansas City’s on the left). (I’m sure the event’s been mentioned on geekswithblogs several times, but I’m on a “staycation” this week, getting cabin fever, and noticed @leebrandt’s tweet today.) I’m looking forward to some of the presentations in the Agile and Patterns tracks. I’m going to have to get up pretty early Saturday morning to descend from St. Louis to Kansas City (Again, no offense – St. Louis is just at a higher elevation*, that’s all), so if you see a tired-looking guy wandering around wearing a St. Louis Day of .NET shirt, please be nice. I’m not sure how much longer registration will be open, but here’s the link: http://kcdc.eventbrite.com/ *Not true – St. Louis is closer to sea level than Kansas City, but I’ll start my drive from the top of the Arch, OK?

• Why did the upgrade from 11.10 to 12.04 ruin my system?

  - by Jared

  After upgrading from Ubuntu 11.10 to 12.04, when I log in, everything is ruined. It's all black, blank white icons, blank black icons on the start menu, and well, nothing works. If I open up Chromium, it looks as though it's in high contrast mode. Is this a bug? Any ideas what could have happened? Can I get 11.10 back? Some photos (can't connect to network in Ubuntu so I had to take pictures with phone): http://i.stack.imgur.com/2dwKl.jpg http://i.stack.imgur.com/N4nA3.jpg http://i.stack.imgur.com/LNFje.jpg

• Is LightDM is broken? Autologin works

  - by Ben

  I recently upgraded my Mythbuntu box to 11.10. LightDM worked for a while and then I configured autologin on my user account. After some time, I've removed some packages to lean down the system. Now when I log out (from either Unity or Gnome Shell) I lose the X session, LightDM doesn't start back up. If I disable autologin through /etc/lightdm/lightdm.conf I get no login screen & no X. As I said, autologin works and gives me a Ubuntu Classic desktop. This is the only reference in dmesg to lightdm; [ 17.351023] type=1400 audit(1329530135.420:19): apparmor="STATUS" operation="profile_load" name="/usr/lib/lightdm/lightdm-guest-session-wrapper" pid=1097 comm="apparmor_parser" Can anyone help?

• Complex algorithm for complex problem

  - by Locaaaaa

  I got this question in an interview and I was not able to solve it. You have a circular road, with N number of gas stations. You know the ammount of gas that each station has. You know the ammount of gas you need to GO from one station to the next one. Your car starts with 0. The question is: Create an algorithm, to know from which gas station you must start driving. As an exercise to me, I would translate the algorithm to C#.

My adsense dashboard is stating I've received a few clicks; but across it still states my account earnings and balance at $0.00. When / How will I start seeing money earned to my account?

• How to position a sprite in a 2D animation skeleton?

  - by Paul Manta

  Given two joints that define a bone, I would like to know how to decide where, between those two joints, I should draw the sprite. This should be a fairly simple thing to solve, but there is one thing that I am not sure about. After I've determined the rotation of the sprite (which is the absolute angle the joints form with the x-axis), I also need to determine the origin point from where I need to start drawing the transformed image. So how should I position the sprite between the two joints? Should I make the center of the image be the midpoint between the two joints, or should I make one the of the joints be the origin? Do these things matter that much (could the wrong positioning make the sprite move oddly during the animation)?

• Running UBUNTU from a USB Flash drive on Acer

  - by Byron Blue

  I've made a bootable USB flash drive to run UBUNTU. The drive works fine on MOST laptops/computers I try: It does not want to start on my (favourite) Acer Aspire 5745 (Windows 7 64 bit). The opening screen has SYSLINUX 4.06 EDD 4.06-pre1 (...) and simply sits there. I was using UBUNTU 12.04.1 64 bit until I tried booting to the Acer this morning. I've tried booting to 10.04 as well (saw this as a fix on a discussion) with the same result. I really want to use the Acer for development and do not want to wipe my Windows 7 from the hard disk. Are there any solutions/answers?
