  • Does moving a file outside NTFS loose data in alertnate data streams?

    - by jay
    I have a lot of files on machine running Windows Server 2008 which I wanted to move to a Fedora machine. How can I keep the attributes stored in, for example, media files (date taken, rating, length, etc) while transfering it to outside the realm of NTFS's Alternate Data Streams. I'm aware that similar metadata exists in other file systems, but what happens when you move these files? And what's the best way to retain them in other file systems?

  • Best practice for organizing/storing character/monster data in an RPG?

    - by eclecto
    Synopsis: Attempting to build a cross-platform RPG app in Adobe Flash Builder and am trying to figure out the best class hierarchy and the best way to store the static data used to build each of the individual "hero" and "monster" types. My programming experience, particularly in AS3, is embarrassingly small. My ultra-alpha method is to include a "_class" object in the constructor for each instance. The _class, in turn, is a static Object pulled from a class created specifically for that purpose, so things look something like this: // Character.as package { public class Character extends Sprite { public var _strength:int; // etc. public function Character(_class:Object) { _strength = _class._strength; // etc. } } } // MonsterClasses.as package { public final class MonsterClasses extends Object { public static const Monster1:Object={ _strength:50, // etc. } // etc. } } // Some other class in which characters/monsters are created. // Create a new instance of Character var myMonster = new Character(MonsterClasses.Monster1); Another option I've toyed with is the idea of making each character class/monster type its own subclass of Character, but I'm not sure if it would be efficient or even make sense considering that these classes would only be used to store variables and would add no new methods. On the other hand, it would make creating instances as simple as var myMonster = new Monster1; and potentially cut down on the overhead of having to read a class containing the data for, at a conservative preliminary estimate, over 150 monsters just to fish out the one monster I want (assuming, and I really have no idea, that such a thing might cause any kind of slowdown in execution). But long story short, I want a system that's both efficient at compile time and easy to work with during coding. Should I stick with what I've got or try a different method? As a subquestion, I'm also assuming here that the best way to store data that will be bundled with the final game and not read externally is simply to declare everything in AS3. Seems to me that if I used, say, XML or JSON I'd have to use the associated AS3 classes and methods to pull in the data, parse it, and convert it to AS3 object(s) anyway, so it would be inefficient. Right?

  • Changing filesystem types "safely"

    - by warren
    Back in Windows 95 OSR2 (I believe), there was a conversion tool that would take your extant FAT16 partition and change it to FAT32 non-destructively (most of the time). Are there any tools like that now for going from one file system type to another in situ without destroying the data? For example, from etx3 to ext4? Or NTFS to XFS?

  • How to recover data from a partially overwritten partition

    - by shredder12
    By mistake, I configured a 900GB partition to be part of a 50GB raid. The sync is complete and my understanding is that only the first 50GB of the bigger partition is overwritten. How do I recover the rest of the data? When I try to mount this partition by identifying it as ext3, it mounts only the 50GB overwritten space. This partition was earlier divided into various logical volumes(all ext3 filesystems) through LVM. Any suggestions?

  • Using www-data through SSH

    - by Fluidbyte
    For development purposes I'm using www-data (on an ubuntu 11.10 server) to ssh in and fire git commands and basic stuff against the webroot. I don't have things like command history, coloring, etc like I do when I ssh in as any other user, so I'm curious how to get this working. I'm assuming I need a `.bashrc' file, but I'm not sure what to include or (more importantly since I could just copy the one from another user) where it goes.

  • Safely reboot prior to recovering data

    - by ELO
    What is the safest (without additional writing to the disk) way to power down computer whose deleted files you want to recover in order to boot from rescue medium? In case of a desktop computer, plugging off the power cord looks like the most direct solution, but are there possible side-effects, apart from losing unsaved data? More problematic seems the laptop, with removing the battery being the equivalent, but is it a good idea overall?

  • Should I keep investing into data structures and algorithms?

    - by Chiron
    These days, I'm investing heavily in data structures and algorithms and trying to solve some programming puzzles. I'm trying to code and solve with Java and Clojure. Am I wasting my time? should I invest more in technologies and frameworks that I already know in order to gain deeper knowledge (the ins and the outs) and be able to code with them more quickly? By studying data structures and algorithms, am I going to become a better programmer or those subjects are only important during college years?

  • Baby's first big CPP project - please help [closed]

    - by jamesson
    So, I need to do a few things to the code here; http://64.90.55.88/SynapseSource-Win.zip What I need to do 1)remove the opengl output window 2)Make it work with latest openni (http://75.98.78.94/default.aspx) - as far as I could tell it only works with a specific older version 3)Improve ram and cpu usage (assuming I don't get what I need from the first two changes) 4)Eventually rebuild it as an object in this sdk; http://cycling74.com/products/sdk/ I tried going through the documentation, but "the needle could not penetrate", alas. For example, I am still unclear about some basic things; a) what are the relative responsibilities of nite vs openni? b) which xml files are always used when the app launches, and what is their format? Many thanks in advance Joe Stavitsky

  • I deleted all files and folders (including hidden) from /home/username/ now in big trouble

    - by jeffery_the_wind
    I am logged into a remote ubuntu server, and I accidentally erased the entire /home/username/ directory for the current user. The only thing left is a hidden directory called .gvfs. I don't need anything of the Documents/Music/etc. Now it is not letting me cd into the /var/www/ directory, which has permissions 666 and it is owned by the current user. I am afraid to disconnect from my ssh session because I don't know if I will be able to get back on. Have I permanently created a problem? Is there a way I can replace the most important files to the /home/username/ directory? Thanks! ** EDIT ** Thanks everyone for the help. I figured the problem with cd into the /var/www/ was actually my permissions in the /var/www/ directory. It was set to 666, changed it to 755 and everything was good again. It doesn't look like anything systematic was ruined by deleting the contents of the user folder.

  • Problem with currency formats and big numbers [on hold]

    - by user132750
    I am working on a dollars to euros/euros to dollars converter in C#. I got the formula, $ times 0.73361 = euro, and I have checked Google with the answers. They were right, (1 dollar equals 0.73 euros). However, it stops working properly when the dollar input value is higher than $1363. This is what I get with $1364: $1364 = 1 000,64 €. I don't know what to do, will someone please help me? Thanks. decimal toEuro; Val.doy = "$" + decimal.Parse(richTextBox1.Text); //Ignore this, it's for the output form CultureInfo eu = new CultureInfo("fr-FR"); toEuro = decimal.Parse(richTextBox1.Text.Trim()); toEuro = toEuro * 0.73361m; richTextBox1.Clear(); Val.duh = toEuro.ToString("C2", eu);

  • How do I implement IDataServiceMetadataProvider and tell my Data Service to use that custom provider

    - by Pwninstein
    There's no obvious entry point for implementing a custom provider for an ADO.NET Data Service using IDataServiceMetadataProvider, and then telling a Data Service to use that provider. Has anyone had any luck in this area? I've tried implementing this interface on my Data Source class, but none of my breakpoints are hit. There is also no (obvious) way to set the provider from the Data Service's DataServiceConfiguration parameter passed in to the InitializeService function. Any help would be appreciated. Thanks!

  • Decode received multipart/form-data request in Cocoa

    - by Snej
    Hi: I wonder if there is any possibility to explicitly decode an incoming multipart/form-data POST request. Is there any lib to handle this safely? Several files are embedded in this request and I want to save these files individually. NSData *data = [(id)CFHTTPMessageCopyBody(request) autorelease]; Content-Type: multipart/form-data; boundary=0xKhTmLbOuNdArY The data content is: --0xKhTmLbOuNdArY Content-Disposition: form-data; name="file1"; filename="fileName1.extension" Content-Type: application/octet-stream; charset=utf-8 ......... --0xKhTmLbOuNdArY Content-Disposition: form-data; name="file2"; filename="fileName2.extension" Content-Type: application/octet-stream; charset=utf-8 ......... --0xKhTmLbOuNdArY--

  • JQuery Datatable Question: Centering column data after data insertion

    - by Chris
    I have a data table that is initially empty and is populated after a particular Javascript call. After the data is inserted into the table, I'd like to center all of the data in one of the columns. I tried specifying this at the initialization step in this way: dTable = $('#dt').datatable({ 'aoColumns': [ null, null, { "sClass" : "center" }] }); The data in the third column was not centered after the insertions were complete. I tried modifying aoColumns after the insertions and redrawing the table as well: dTable.fnSettings().aoColumns[2].sClass = "center"; dTable.fnDraw(); This did not work either. So my question is simply how should I go about telling the data table to center the data in the third column? Thanks in advance for your suggestions. Chris

  • using document.createDocumentFragment() child dom elements that contain jQuery.data

    - by taber
    I want to use document.createDocumentFragment() to create an optimized collection of HTML elements that contain ".data" coming from jQuery (v 1.4.2), but I'm kind of stuck on how to get the data to surface from the HTML elements. Here's my code: var genres_html = document.createDocumentFragment(); $(xmlData).find('genres').each(function(i, node) { var genre = document.createElement('a'); $(genre).addClass('button') .attr('href', 'javascript:void(0)') .html( $(node).find('genreName:first').text() ) .data('genreData', { id: $(node).find('genreID:first').text() }); genres_html.appendChild( genre.cloneNode(true) ); }); $('#list').html(genres_html); // error: $('#list a:first').data('genreData') is null alert($('#list a:first').data('genreData').id); What am I doing wrong here? I suspect it's probably something with .cloneNode() not carrying over the data when the element is appended to the documentFragment. Sometimes there are tons of rows so I want to keep things pretty optimized, speed-wise. Thanks!

  • Workflow for statistical analysis and report writing

    - by ws
    Does anyone have any wisdom on workflows for data analysis related to custom report writing? The use-case is basically this: Client commissions a report that uses data analysis, e.g. a population estimate and related maps for a water district. The analyst downloads some data, munges the data and saves the result (e.g. adding a column for population per unit, or subsetting the data based on district boundaries). The analyst analyzes the data created in (2), gets close to her goal, but sees that needs more data and so goes back to (1). Rinse repeat until the tables and graphics meet QA/QC and satisfy the client. Write report incorporating tables and graphics. Next year, the happy client comes back and wants an update. This should be as simple as updating the upstream data by a new download (e.g. get the building permits from the last year), and pressing a "RECALCULATE" button, unless specifications change. At the moment, I just start a directory and ad-hoc it the best I can. I would like a more systematic approach, so I am hoping someone has figured this out... I use a mix of spreadsheets, SQL, ARCGIS, R, and Unix tools. Thanks! PS: Below is a basic Makefile that checks for dependencies on various intermediate datasets (w/ ".RData" suffix) and scripts (".R" suffix). Make uses timestamps to check dependencies, so if you 'touch ss07por.csv', it will see that this file is newer than all the files / targets that depend on it, and execute the given scripts in order to update them accordingly. This is still a work in progress, including a step for putting into SQL database, and a step for a templating language like sweave. Note that Make relies on tabs in its syntax, so read the manual before cutting and pasting. Enjoy and give feedback! http://www.gnu.org/software/make/manual/html%5Fnode/index.html#Top R=/home/wsprague/R-2.9.2/bin/R persondata.RData : ImportData.R ../../DATA/ss07por.csv Functions.R $R --slave -f ImportData.R persondata.Munged.RData : MungeData.R persondata.RData Functions.R $R --slave -f MungeData.R report.txt: TabulateAndGraph.R persondata.Munged.RData Functions.R $R --slave -f TabulateAndGraph.R report.txt

  • Data Model Evolution

    - by redleafong
    Hey guys, When writing code I am seeing requirements to change data models (e.g. adding/changing/removing data members from a class). When these data models belong to an interface, it seems difficult to change without breaking the existing client codes. So I am wondering if there is any best practice of designing interfaces/data models in a way to minimize the impact during evolution. The closest thing I can find from google is data contract versioning. But that seems to be a .net specific topic. I am wondering if the same practice applies to the Java world, or there is a different or generic way to deal with data model evolution. Thanks

  • should jQuery data be chainable?

    - by pedalpete
    I'm trying to add multiple jQuery data entries to a single element. I suspected that the following would work jQuery('td.person#a'+personId).data('email',thisPerson.email).data('phone',thisPerson.phone); However, I am getting nothing but errors when I do this. jQuery('td.person#a'+personId).data('email',thisPerson.email); jQuery('td.person#a'+personId).data('phone',thisPerson.phone); is there another way to get more than one data entry on an element? Hopefully chained?

  • Using protocol buffers for a comprehensive data strategy for Windows Mobile devices

    - by Steve
    I have started reading some of the posts related to protocol buffers. The serialization method seems very appropriate for the transfer of data to and from web servers. Has anyone considered using a method like this to save and retrieve data on the mobile device itself? (i.e. a replacement for a traditional database / orm layer) Where would the data be persisted? How would the data be queried? Would it make sense to store the data in a traditional database (SqlCE or SqlLite) with a few "searchable" columns and then one column for the serialized data? Thoughts? Am I out on a limb here? Thank you!

  • Estimating the boundary of arbitrarily distributed data

    - by Dave
    I have two dimensional discrete spatial data. I would like to make an approximation of the spatial boundaries of this data so that I can produce a plot with another dataset on top of it. Ideally, this would be an ordered set of (x,y) points that matplotlib can plot with the plt.Polygon() patch. My initial attempt is very inelegant: I place a fine grid over the data, and where data is found in a cell, a square matplotlib patch is created of that cell. The resolution of the boundary thus depends on the sampling frequency of the grid. Here is an example, where the grey region are the cells containing data, black where no data exists. OK, problem solved - why am I still here? Well.... I'd like a more "elegant" solution, or at least one that is faster (ie. I don't want to get on with "real" work, I'd like to have some fun with this!). The best way I can think of is a ray-tracing approach - eg: from xmin to xmax, at y=ymin, check if data boundary crossed in intervals dx y=ymin+dy, do 1 do 1-2, but now sample in y An alternative is defining a centre, and sampling in r-theta space - ie radial spokes in dtheta increments. Both would produce a set of (x,y) points, but then how do I order/link neighbouring points them to create the boundary? A nearest neighbour approach is not appropriate as, for example (to borrow from Geography), an isthmus (think of Panama connecting N&S America) could then close off and isolate regions. This also might not deal very well with the holes seen in the data, which I would like to represent as a different plt.Polygon. The solution perhaps comes from solving an area maximisation problem. For a set of points defining the data limits, what is the maximum contiguous area contained within those points To form the enclosed area, what are the neighbouring points for the nth point? How will the holes be treated in this scheme - is this erring into topology now? Apologies, much of this is me thinking out loud. I'd be grateful for some hints, suggestions or solutions. I suspect this is an oft-studied problem with many solution techniques, but I'm looking for something simple to code and quick to run... I guess everyone is, really! Cheers, David
