• Visual C++, CMap object save to blob column

  - by ilansch

  I have a MFC CMap object, each object stores 160K~ entries of long data. I need to store it on Oracle SQL. we decided to save it as a blob. since we do not want to make additional table. we also thought about saving it as local file and point the SQL column to that file, but we rather just keep it as blob on the server and clear the table every couple of weeks. The table has a sequential key as ID, and 2 column of time. I need to add the blob column in order to store on every row that CMap. Can you recommend a guide to do so (read/write Map to blob or maybe a clob) ? Thanks.

• How do I duplicate a Box2d simulation, mid-simulation?

  - by Whyte

  I want to serialize the state mid-game, send it over the network to an identical computer (same CPU, same OS, same binary), load it there, and have the two games run in tandem doing the exact same simulation, without one of them drifting off and going haywire. In short: I want pop-in, pop-out networking support on my HIGHLY physics-intensive game, where sending object coordinates every few seconds is impossible, due to having thousands of objects, and many clients. I tried this with Box2D, and saving an object's location/velocity/etc wasn't enough... there's internal state that's not accessible through any public methods. My current workaround is to force EVERY client to save its entire worldstate and reload it from scratch, whenever a new player connects... but this is obviously bad practice, because it hangs the game for everyone whenever someone new connects. However, it works, with zero desynchronization. So, anyone know of any other techniques that can help me? Or should I just kiss my project goodbye?

• How to implement custom texture formats in Android?

  - by random1337

  What I know: Android can load PNG, BMP, WEBP,... via BitmapFactory. What I want to achive: Load my own 2D file format (e.g. 1-bit texture with a 1-bit alpha channel) and output a RGBA8888 texture. Question: Is there any interface to achieve this?(or any other way) The resulting image is used as a texture for a 3D model. Why would you do that? Saving phone memory and download bandwidth while expanding the texture at runtime to RAM seems reasonable for very simple textures.

• Creating thumbnails with the same name as the pictures

  - by Duby

  Please, here is my little code for creating thumbnails of pictures saved in a folder named 'pictures', and saving them in another folder named 'thumbs'. ! /bin/bash for i in *.jpg do convert -thumbnail 100 pictures/$i thumbs/$i done However, there two things the program doesn't do: 1) It does not retain the name of the pictures in the thumbnail. For instance, I would want it to generate a thumbnail with the name pic.jpg for a picture named pic.jpg 2) Also, when I run the program, i don't want it to generate the thumbnail for a picture it has already generated its thumbnail, unless that picture has been modified. Any help will be very much appreciated. Thank you

• Data structure for file search

  - by poly

  I've asked this question before and I got a few answers/idea, but I'm not sure how to implement them. I'm building a telecom messaging solution. Currently, I'm using a database to save my transaction/messages for the network stack I've built, and as you know it's slower than using a data structure (hash, linkedlist, etc...). My problem is that the data can be really huge, and it won't fit in the memory. I was thinking of saving the records in a file and the a key and line number in a hash, then if I want to access some record then I can get the line number from the hash, and get it from the file. I don't know how efficient is this; I think the database is doing a way better job than this on my behalf. Please share whatever you have in mind.

• Best Way to Handle Meta Information in a SQL Database

  - by danielhanly.com

  I've got a database where I want to store user information and user_meta information. The reason behind setting it up in this way was because the user_meta side may change over time and I would like to do this without disrupting the master user table. If possible, I would like some advice on how to best set up this meta data table. I can either set it as below: +----+---------+----------+--------------------+ | id | user_id | key | value | +----+---------+----------+--------------------+ | 1 | 1 | email | [email protected] | | 2 | 1 | name | user name | | 3 | 1 | address | test address | ... Or, I can set it as below: +----+---------+--------------------+--------------------+--------------+ | id | user_id | email | name | address | +----+---------+--------------------+--------------------+--------------+ | 1 | 1 | [email protected] | user name | test address | Obviously, the top verison is more flexible, but the bottom version is space saving and perhaps more efficient, returning all the data as a single record. Which is the best way to go about this? Or, am I going about this completely wrong and there's another way I've not thought of?

• Help with off-game tasks

  - by peoro

  I love writing video games for fun, and often do that. I noticed, anyway, that most of the times implementing the gameplay itself doesn't take too much time to me (maybe because I already did that plenty times and know what and how to do for most of the things), but when I try to implement off-game stuff I get lost. By off-game I mean what is not gameplay: menus, cutscenes between levels, world map to choose levels, saving and loading status, managing replays ... Only tried to write a few of these a few times, but always failed; that's why I never really completed and distributed a game. Are these common problems? And where should I start to do this? Where could I find some books/guides about such stuff?

• Can't reset BackInTime snapshot path

  - by user87337

  I've been using BackInTime with Ubuntu 12.04. The disk I was saving to is no longer available. BackInTime insists that I bring it back. (It says "Can't find snapshots folder. If it is on a removable drive please plug it and then press OK") No matter what I've tried, I can't seem to get beyond this point. I've even tried removing BackInTime and re-installing it. The problem persists. How can I change the snapshots path without the missing disk? ---Jack

• Using PDO for Data Management

  - by edorahg

  This question is more a design oriented question than a code specific question. I am new to PHP and I am planning to use PDO as a data access layer. Say for instance I have a class called CITY. Now if I need to create an instance of this class, what is the best technique. Should have a singleton DB access class which is used to write and read data from the db layer. OR should I delegate it to the individual class object. For example if I invoke city.save() (city is a class), then the city class will handle the saving of that city object's data into the database. Excuse my ignorance but i have a java background and therefore trying to understand what is the best design principle for data management when using php.

• Synchronizing (updating) published files

  - by MucMug

  How can I update a published file and maintain the same URL? After saving an update of a published file on my desktop, it will automatically "synchronise" with the corresponding files at UbuntuOne (and it does). Problem is that the "new file", actually the updated file with the same name, is no longer published. Pressing the publish button results is a new URL. I now have to mail new URL's and change embedded links, as old URL will result in a failure to find the updated file (or indeed any file). I am not sure if it is a bug or a design flaw (maybe intentional?), but it seems strange to me.

• Replacement for Vern Buerg's list.com in 64 bit Windows 7

  - by Kevin

  I would like to find a replacement for list.com, specifically the ability to accept piped input. For example: p4 sync -n | list which accepts the output of the perforce command and displays the results in the viewer/editor for manipulation or saving. I know that I would send the output to a file and then open the file in the viewer/editor but I use it for temporary results. List.com doesn't work on 64 bit Windows 7.

• DPI for EMF files

  - by KrisTrip

  Do EMF files have a DPI that can be set? I have an application that allows saving an image in multiple formats (including EMF). I allow the user to specify the resolution/DPI for the image(s). However, I cannot find a way to do this for a MetaFile in C#. Is this possible or does EMF not have a DPI since it is a vector graphics format?

  Do you know a web service that's able let's say get a full list of cities in the world with names, short names like PAR for Paris and time zones? Or at least query by city name: Paris - timezone=+02:00, abbrev=PAR Also, what I see here: http://www.earthtools.org/webservices.htm#timezone offset The number of hours offset from UTC disregarding any correction for daylight saving time. That's not a desired result. Of course we need this correction!
