Vertex data split into separate buffers or one one structure?

- by kiba2

Is it better to have all vertex data in one structure like this: class MyVertex { int x,y,z; int u,v; int normalx, normaly, normalz; } Or to have each component (location, normal, texture coordinates) in separate arrays/buffers? To me it always seemed logical to keep the data grouped together in one structure because they'd always be the same for each instance of a shared vertex and that seems to be true for things like character models (ex: the normal should be an average of adjacent normals for smooth lighting). One instance where this doesn't seem to work is other kinds of meshes like say a cube where the texture coordinates for each may be the same but that causes them to be different where the vertices are shared. Does everybody normally keep them separate? Won't this make them less space efficient if there needs to be an instance of texture coordinates and normals for each triangle vertex (They won't be indexed)? Can OpenGL even handle this mixing of indexed (for location) vs non-indexed buffers in the same VBO?

Many ui panels needs interaction with same object

- by user877329

I am developing a tool for simulating systems like the Gray-Scott model (That is systems where spatial distribution depends on time). The actual model is loaded from a DLL or shared object and the simulation is performed by a Simulation object. There are at least two situations when the simulation needs to be destroyed: The user loads a new model The user changes the size of the domain To make sure nothing goes wrong, the current Model, Simulation, and rendering Thread are all managed by an ApplicationState object. But the two cases above are initiated from two different UI objects. Is it then ok to distribute a reference to the ApplicationState object to all panels that need to access at least one method on the ApplicationState object? Another solution would be to use aggregation so that the panel from which the user chooses model knows the simulation parameter panel. Also, the ApplicationState class seems somewhat clumsy, so I would like to have something else

How can I make zaz save its profile data?

- by RolandiXor - The Ice Man

I've been playing Zaz recently as a time waster and stress beater, but it seems not to be actively maintained, and is not saving profile data under Ubuntu 12.10. It's getting to be more stressful than fun, because it keeps crashing, and under Unity, Gnome Shell, KDE (in other words, any opengl enabled WM) it makes the GPU lockup. How can I make it save the profile data or create a profile that I can manually place my level info in? I'm tired of playing the same levels over and over and not being able to start from the ones I've already passed. I am still yet to find any info on fixing this. Any clues?

Iomega Home Media Network Hard Drive 1TB Cloud Edition failed, data recovery?

- by lonbon69

I have a Iomega Home Media Network Drive Cloud Edition 1TB that started clicking and then displayed a failure LED code Power LED and Red LED. I removed the SATA drive and inserted in a 'All in 1 HDD Docking Station' and connected to laptop by USB - Laptop has Win 7 OS. The dock is seen as drive E but cannot access and says 0% data etc. The drive does spin up when I power the dock. Web searches say the drive has EXT3 file system and to use Ubuntu to access drive. I have now setup a dual boot laptop but still do not see the drive using ubuntu. Is there something else I need to do to get it recognised etc. I really would like to recover the data, any suggestions please?

UK Data Breaches Up by 10 fold in 10 years.

- by TATWORTH

At http://www.v3.co.uk/v3-uk/news/2201863/uk-data-breaches-rocket-by-1-000-percent-over-past-five-years there is an interesting report on the increase in data breaches reported in the UK.A lot of this increase may simply a change in legislation that has made reporting a statutory obligation.Some questions to ask yourself:Are server logs checked for untoward activity?Do you have a reporting policy if something is amiss?Did you design security in for the start of your application design?Do you log for example failed logons?Do you run tools to check for code integrity?Is my defense, a strategy of defense in depth?Do you realise that 60% of hack attacks are internal?Whilst SQL Injection is a problem that affects practically all application code platforms, within Microsoft Applications do you run FXCOP? Do you run any of the other free tools for checking?

Is a blob more efficient than a varchar for data that can be ANY size?

- by BillyNair

When setting up a database I want to use the most efficient data type for potentially fairly long data. Currently my project is to store song titles and thoughts pertaining to that song. Some titles might be 5 characters or longer than 100 characters and the thoughts could run pretty long. Is it more efficient to use a varchar set to 8000 or to use a blob? Is using a blob the same as a varchar, in that there is a set size it is allocated regardless of what it holds? or is it just a pointer and it doesn't really use much space on the table? Is there a certain set size of a blob in KB or is it expandable?

Zelda-style top-down RPG. How to store tile and collision data?

- by Delerat

I'm looking to build a Zelda: LTTP style top-down RPG. I've read a lot on the subject and am currently going back and forth on a few solutions. I'm using C#, MonoGame, and Tiled. For my tile maps, these are the choices I can see in front of me: Store each tile as its own array. Each one having 3-4 layers, texture/animation, depth, flags, and maybe collision(depending on how I do it). I've read warning about memory issues going this route, and my biggest map will probably be 160x120 tiles. My average map however will be about 40x30. The number of tiles might cut in half if I decide to double my tile size, which is currently 16x16. This is the most appealing approach for me, as I feel like I would know how to save maps, make changes, and separate it into chunks for collision checks. Store the static parts of my tile map in multiple arrays acting as the different layers. Then I would just use entities for anything that wasn't static. All of the other tile data such as collisions, depth, etc., would be stored in their own layers as well I guess? This way just seems messy to me though. Regardless of which one I choose, I'm also unsure how to plan all of that other tile data. I could write a bunch of code that would know which integer represents what tile and it's data, but if I changed a tileset in Tiled and exported it again, all of those integers could potentially change and I'd have to adjust a whole bunch of code. My other issue is about how I could do collision. I want to at least support angled collision that slides you around the corners of objects like LTTP does, if not more oddball shapes as well. So do I: Store collision as a flag for binary collision. Could I get this to support angles? Would it be fine to store collision as an integer and have each number represent a certain angle of collision? Store a list of rectangles or other shapes and do collision that way? Sorry for the large two-part(three-part?) question. I felt like these needed to be asked together as I believe each choice influences the other.

How can I fix a very broken Ubuntu installation without losing data?

- by jredkai

Okay guys, I was installing a program (I do not remember the name). When I did sudo apt-get update I was given missing dependencies. It told me to sudo apt-get install -f which deleted just about every dependency needed for Ubuntu, now I cannot log in or anything, now in GRUB it actually says Debian instead of Ubuntu. I have tons of important data in that partition. Can I some how use the live cd to fix this problem??? I mean like re-install without losing data. Any help is greatly appreciated!!!

Does the direction of storage make us bad data citizens?

- by simonsabin

My career started at a company where we hardly had email, the network was a 10base2 affair with cables running all around the office. You used floppy disks and the thought of a GB of data was absurd. You had to look after every byte and only keep what you really needed. Whilst the cost of the spinning disks gradually falls the cost and size of flash storage continues to plummet. The new Crucial SSD is £380 for 1TB I can now keep 128GB of data on a SD card the size of my finger. It only costs...(read more)

How to visualize real time data on Android? [closed]

- by matarsak

I want to build and android app that visualizes real time data (2D animation). I set up a UDP channel that get the data, now I want to visualize it. I know that I can use OpenGL ES, but after a few weeks, I dont think that I'm able to learn that. What about Android Processing? Could it be used for an extensive visualization task like this? or is it limited in some way? I've heard it's not hard learn. Any other options?

How to export SSIS to Microsoft Excel without additional software?

- by Dr. Zim

This question is long winded because I have been updating the question over a very long time trying to get SSIS to properly export Excel data. I managed to solve this issue, although not correctly. Aside from someone providing a correct answer, the solution listed in this question is not terrible. The only answer I found was to create a single row named range wide enough for my columns. In the named range put sample data and hide it. SSIS appends the data and reads metadata from the single row (that is close enough for it to drop stuff in it). The data takes the format of the hidden single row. This allows headers, etc. WOW what a pain in the butt. It will take over 450 days of exports to recover the time lost. However, I still love SSIS and will continue to use it because it is still way better than Filemaker LOL. My next attempt will be doing the same thing in the report server. Original question notes: If you are in Sql Server Integrations Services designer and want to export data to an Excel file starting on something other than the first line, lets say the forth line, how do you specify this? I tried going in to the Excel Destination of the Data Flow, changed the AccessMode to OpenRowSet from Variable, then set the variable to "YPlatters$A4:I20000" This fails saying it cannot find the sheet. The sheet is called YPlatters. I thought you could specify (Sheet$)(Starting Cell):(Ending Cell)? Update Apparently in Excel you can select a set of cells and name them with the name box. This allows you to select the name instead of the sheet without the $ dollar sign. Oddly enough, whatever the range you specify, it appends the data to the next row after the range. Oddly, as you add data, it increases the named selection's row count. Another odd thing is the data takes the format of the last line of the range specified. My header rows are bold. If I specify a range that ends with the header row, the data appends to the row below, and makes all the entries bold. if you specify one row lower, it puts a blank line between the header row and the data, but the data is not bold. Another update No matter what I try, SSIS samples the "first row" of the file and sets the metadata according to what it finds. However, if you have sample data that has a value of zero but is formatted as the first row, it treats that column as text and inserts numeric values with a single quote in front ('123.34). I also tried headers that do not reflect the data types of the columns. I tried changing the metadata of the Excel destination, but it always changes it back when I run the project, then fails saying it will truncate data. If I tell it to ignore errors, it imports everything except that column. Several days of several hours a piece later... Another update I tried every combination. A mostly working example is to create the named range starting with the column headers. Format your column headers as you want the data to look as the data takes on this format. In my example, these exist from A4 to E4, which is my defined range. SSIS appends to the row after the defined range, so defining A4 to E68 appends the rows starting at A69. You define the Connection as having the first row contains the field names. It takes on the metadata of the header row, oddly, not the second row, and it guesses at the data type, not the formatted data type of the column, i.e., headers are text, so all my metadata is text. If your headers are bold, so is all of your data. I even tried making a sample data row without success... I don't think anyone actually uses Excel with the default MS SSIS export. If you could define the "insert range" (A5 to E5) with no header row and format those columns (currency, not bold, etc.) without it skipping a row in Excel, this would be very helpful. From what I gather, noone uses SSIS to export Excel without a third party connection manager. Any ideas on how to set this up properly so that data is formatted correctly, i.e., the metadata read from Excel is proper to the real data, and formatting inherits from the first row of data, not the headers in Excel? One last update (July 17, 2009) I got this to work very well. One thing I added to Excel was the IMEX=1 in the Excel connection string: "Excel 8.0;HDR=Yes;IMEX=1". This forces Excel (I think) to look at all rows to see what kind of data is in it. Generally, this does not drop information, say for instance if you have a zip code then about 9 rows down you have a zip+4, Excel without this blanks that field entirely without error. With IMEX=1, it recognizes that Zip is actually a character field instead of numeric. And of course, one more update (August 27, 2009) The IMEX=1 will succeed importing data with missing contents in the first 8 rows, but it will fail exporting data where no data exists. So, have it on your import connection string, but not your export Excel connection string. I have to say, after so much fiddling, it works pretty well.

SSRS 2005: How do I make available varbinary data for download in a report?

- by Angelo

Hi, SSRS newbie question here... I have a table where one column is varbinary(max) data. I would like to make a report that makes this data available for download as a hyperlink so the user can just click on the item and get a file download dialog for the binary data. In this particular case, the binary data happens to be the content of old pdf files, but that shouldn't matter. I tried searching around but I can't find any pointers on how to do this. It seems to me that it should be possible. There are ways to display images in a report using varbinary data, so it makes sense that one should be able to make arbitrary binary data downloadable on a report, right?

How do I identify and fix the cause of transaction log growth on SIMPLE recovery model databases?

- by Stuart B

I recently upgraded our SQL Server 2008 installations to service pack 2. One of our databases is on the simple recovery model, but its transaction log is growing extremely fast. The path I'm currently investigating is that we have a transaction somewhere out there stuck in active state. Here is why: select name, recovery_model_desc, log_reuse_wait_desc from sys.databases where name in ('SimpleDB') name recovery_model_desc log_reuse_wait_desc SimpleDB SIMPLE ACTIVE_TRANSACTION When I check my active transactions, I get the following. Note that I installed SP2 and restarted our server on 12/25 at around noonish. select transaction_id, name, transaction_begin_time, transaction_type from sys.dm_tran_active_transactions transaction_id name transaction_begin_time transaction_type 233 worktable 2010-12-25 12:44:29.283 2 236 worktable 2010-12-25 12:44:29.283 2 238 worktable 2010-12-25 12:44:29.283 2 240 worktable 2010-12-25 12:44:29.283 2 243 worktable 2010-12-25 12:44:29.283 2 245 worktable 2010-12-25 12:44:29.283 2 62210 tran_sp_MScreate_peer_tables 2010-12-25 12:45:00.880 1 55422856 user_transaction 2010-12-28 16:41:56.703 1 55422889 SELECT 2010-12-28 16:41:57.303 2 470 LobStorageProviderSession 2010-12-25 12:44:30.510 2 Note that according to the documentation a transaction_type of 1 means read/write, and 2 means read-only. So, my line of thinking is that the trans_sp_MScreate_peer_tables transaction is stuck for some reason and holding up transaction log truncation. Is this a plausible scenario? Correct me if my line of thinking is off, as I'm not a SQL Server expert. If this is correct, how do I erase that transaction so that my transaction log is truncated as usual?

Is there a format or service for resume/CV data?

- by Ben Dauphinee

I have noticed through the process of signing up for various freelance and job seeking or professional network sites that they all want your resume/CV data. And I am really getting tired of copy/pasting this data, especially since I have a website. Is there a standard format or service somewhere that I do not know about for this data? If not, does anyone want to help me build something like this out? I'm thinking a service similar to OpenID that allows you to maintain a central resume to have your data pulled from. No more filling in the same data over and over, and having to maintain the copies on any of the plethora of websites that have that data. Takers?

How can I remotely tell what brand/model internal SCSI card is installed in a machine?

- by edmicman

I am doing some consulting work for a previous employer upgrading and migrating old servers to new hardware. There is an existing file server (HP ProLiant DL380) that has an tape backup drive connected; it is using a SCSI interface and I'm pretty sure it's using an internal SCSI card. They are upgrading to a new server hardware (HP ProLiant DL160 G6). The old server is 2U, the new one 1U and we would want to move the tape drive to the new server, too. I'm trying to figure out if the SCSI card in the old server would be able to be installed in the new one or if we'll need to source a new card; mostly I don't know for sure the height of the card and if it's low-profile enough that it would fit in the new server. There is not much of a technical resource onsite and the old server is in-use anyway so I would like to avoid making a trip in myself or trying to have someone onsite pop open the case and tell me what card is there. It's running Windows Server 2003 - is there a way to tell from say Device Manager what make and model the SCSI card might be? Or any other system diagnostic program or something that would give me hardware info like that? Thanks for any info!

How best to convert CakePHP date picker form data to a PHP DateTime object?

'-' . $this->data['Mymodel']['mydatefield']['day']; $mydatefield = DateTime::createFromFormat('Y-m-d', $datestring); } There absolutly has to be a better way to do this - I just haven't found the CakePHP way yet... What I would like to do is: function add() { # ... (if we have some submitted data) $mydatefield = $this->data['Mymodel']['mydatefiled']; # obviously doesn't work }

Next, Previous Records Using Named Scope

- by keruilin

I have a model for which I want to retrieve the next record(s) and previous record(s). I want to do this via a named_scope on the model, and also pass in as an argument the X number of next/previous records to return. For example, let's say I have 5 records: Record1 Record2 Record3 Record4 Record5 I want to be able to call Model.previous or Model.previous(1) to return Record2. Similarly, I want to be able to call Model.next or Model.next(1) to return Record4. As another example I want to be able to call Model.previous(2) to return Record3. I think you get the idea. How can I accomplish this?

Why does this PHP script interfere with my CSS layout?

- by CT

This page uses $_GET to grab an asset id and query a mysql database and return some information. If 'id' does not match anything, no results are displayed but the page looks fine. If 'id' is null an error would occur at $id = $_GET["id"] or die(mysql_error()); When this occurs, they page layout is not displayed correctly. How do I fix this? Bonus question: How would I get a message like "No matching results found" or something when the id does not match any id in the database or is null.

How to think in data stores instead of databases?

- by Jim

As an example, Google App Engine uses data stores, not a database, to store data. Does anybody have any tips for using data stores instead of databases? It seems I've trained my mind to think 100% in object relationships that map directly to table structures, and now it's hard to see anything differently. I can understand some of the benefits of data stores (e.g. performance and the ability to distribute data), but some good database functionality is sacrificed (e.g. joins). Does anybody who has worked with data stores like BigTable have any good advice to working with them?

Showing a loading spinner only if the data has not been cached.

- by Aaron Mc Adam

Hi guys, Currently, my code shows a loading spinner gif, returns the data and caches it. However, once the data has been cached, there is a flicker of the loading gif for a split second before the data gets loaded in. It's distracting and I'd like to get rid of it. I think I'm using the wrong method in the beforeSend function here: $.ajax({ type : "GET", cache : false, url : "book_data.php", data : { keywords : keywords, page : page }, beforeSend : function() { $('.jPag-pages li:not(.cached)').each(function (i) { $('#searchResults').html('<p id="loader">Loading...<img src="../assets/images/ajax-loader.gif" alt="Loading..." /></p>'); }); }, success : function(data) { $('.jPag-current').parent().addClass('cached'); $('#searchResults').replaceWith($(data).find('#searchResults')).find('table.sortable tbody tr:odd').addClass('odd'); detailPage(); selectForm(); } });

How can I structure and recode messy categorical data in R?

- by briandk

I'm struggling with how to best structure categorical data that's messy, and comes from a dataset I'll need to clean. The Coding Scheme I'm analyzing data from a university science course exam. We're looking at patterns in student responses, and we developed a coding scheme to represent the kinds of things students are doing in their answers. A subset of the coding scheme is shown below. Note that within each major code (1, 2, 3) are nested non-unique sub-codes (a, b, ...). What the Raw Data Looks Like I've created an anonymized, raw subset of my actual data which you can view here. Part of my problem is that those who coded the data noticed that some students displayed multiple patterns. The coders' solution was to create enough columns (reason1, reason2, ...) to hold students with multiple patterns. That becomes important because the order (reason1, reason2) is arbitrary--two students (like student 41 and student 42 in my dataset) who correctly applied "dependency" should both register in an analysis, regardless of whether 3a appears in the reason column or the reason2 column. How Can I Best Structure Student Data? Part of my problem is that in the raw data, not all students display the same patterns, or the same number of them, in the same order. Some students may do just one thing, others may do several. So, an abstracted representation of example students might look like this: Note in the example above that student002 and student003 both are coded as "1b", although I've deliberately shown the order as different to reflect the reality of my data. My (Practical) Questions Should I concatenate reason1, reason2, ... into one column? How can I (re)code the reasons in R to reflect the multiplicity for some students? Thanks I realize this question is as much about good data conceptualization as it is about specific features of R, but I thought it would be appropriate to ask it here. If you feel it's inappropriate for me to ask the question, please let me know in the comments, and stackoverflow will automatically flood my inbox with sadface emoticons. If I haven't been specific enough, please let me know and I'll do my best to be clearer.

Is there a way to only backup a SQL 2005 database structure fully, but only the data in a certain se

- by TheSoftwareJedi

I have several schemas in my database, and the largest one ("large" meaning disk space consumed) is my "web" schema which is a denormalized copy of data in the operational schemas. This denormalized data is able to be reconstructed at anytime, and is merely there for extremely fast read purposes. Since the data is redundant, and VERY large - I'd like to exclude it from being backed up. I already have stored procedures that can regenerate all of the data in that schema in a couple of hours - for use in the event of a failure. I assume I can split the tables in this schema out to another data file or such (ideally even on another drive for faster reads), but is there a way to never have that data file backup, yet still in the event of a failure its structure could be restored (and other DDL stuff like procs, views, etc)? Somewhat related, can I also have these tables not do transaction logging, if I go to "Full" backup mode for the rest of the database?
